                             UNDERWRITING AGREEMENT


                                                              New York, New York
                                                                   July 22, 1999


To the Representatives named in Schedule I
   hereto of the Underwriters named in
   Schedule II hereto



Ladies and Gentlemen:

               1. Introduction. Massachusetts RRB Special Purpose Trust BEC-1, a
Delaware business trust to be formed (the "Trust"), will sell to the
underwriters named in Schedule II hereto (the "Underwriters"), for whom you (the
"Representatives") are acting as representatives, the principal amount of
Massachusetts RRB Special Purpose Trust BEC-1 Rate Reduction Certificates
identified in Schedule I hereto (the "Certificates"). If the firm or firms
listed in Schedule I hereto include only the firm or firms listed in Schedule II
hereto, then the terms "Underwriters" and "Representatives," as used herein,
shall each be deemed to refer to such firm or firms.

         The Trust will be formed pursuant to a Declaration of Trust to be dated
prior to the Closing Date (as hereinafter defined) (the "Declaration of Trust"),
by The Bank of New York (Delaware), as Delaware Trustee (the "Delaware
Trustee"), and the Massachusetts Development Finance Agency and the
Massachusetts Health and Educational Facilities Authority (each an "Agency,"
and, collectively, the "Agencies"), acting jointly as settlors thereunder
pursuant to Chapter 164 of the Massachusetts Acts of 1997 (the "Statute"). The
Certificates will be issued pursuant to a Certificate Indenture dated as of July
29, 1999 (the "Certificate Indenture"), between the Trust, the Delaware Trustee
and The Bank of New York, as Certificate Trustee (the "Certificate Trustee").
The assets of the Trust will consist solely of the BEC Funding LLC Notes (the
"Notes"), issued by BEC Funding LLC, a Delaware limited liability company (the
"Note
<PAGE>   2
Issuer"), and the payments received with respect thereto. The Notes will be
issued pursuant to a Note Indenture dated as of July 29, 1999 (the "Note
Indenture"), between the Note Issuer and The Bank of New York, as Note Trustee
(the "Note Trustee"), and purchased by the Trust pursuant to a Note Purchase
Agreement dated as of July 29, 1999 (the "Note Purchase Agreement"), between the
Note Issuer and the Trust. Each Class of Certificates will correspond to a Class
of Notes and will represent fractional undivided beneficial interests in such
underlying Class of Notes and the proceeds thereof. The Notes will be secured
primarily by, and will be payable from, the Transition Property described in the
Issuance Advice Letter. Such Transition Property will be sold to the Note Issuer
by Boston Edison Company, a Massachusetts corporation (the "Company"), pursuant
to a Transition Property Purchase and Sale Agreement dated as of July 29, 1999
(the "Sale Agreement"), between the Company, as Seller, and the Note Issuer. The
Transition Property will be serviced pursuant to a Transition Property Servicing
Agreement dated as of July 29, 1999 (as amended and supplemented from time to
time, the "Servicing Agreement"), between the Company, as Servicer, and the Note
Issuer.

         Capitalized terms used and not otherwise defined herein shall have the
respective meanings given to them in the Note Indenture.

               2. Representations and Warranties.

            (a) Each of the Company and the Note Issuer represents and warrants
        to, and agrees with, each Underwriter as set forth below in this Section
        2(a). Certain terms used in this Section 2(a) are defined in paragraph
        (iii) below.

                (i) If the offering of the Certificates is a Delayed Offering
            (as specified in Schedule I hereto), paragraph (a) below is
            applicable and, if the offering of the Certificates is a Non-Delayed
            Offering (as so specified), paragraph (b) below is applicable.

                (1) The Note Issuer, the Notes and the Certificates meet the
                    requirements for the use of Form S-3 under the Securities
                    Act of 1933 (the "Act"), and the Note Issuer has filed with
                    the Securities and Exchange Commission (the "SEC") a
                    registration statement (file number 333-74671) on such Form,
                    including a basic prospectus, for registration under the Act
                    of the offering and sale of the Certificates. The Note
                    Issuer may have filed one or more amendments thereto, and
                    may have used a Preliminary Final Prospectus, each of which
                    has previously been furnished to you. Such registration
                    statement, as so amended, and in the form heretofore
                    delivered to you, has become effective. The offering of the
                    Certificates is a Delayed Offering and, although the Basic
                    Prospectus may not include all the information with respect
                    to the Certificates and the offering thereof required by the
                    Act and


                                       2
<PAGE>   3
                    the rules thereunder to be included in the Final Prospectus,
                    the Basic Prospectus includes all such information required
                    by the Act and the rules thereunder to be included therein
                    as of the Effective Date. The Note Issuer will next file
                    with the SEC pursuant to Rules 415 and 424(b)(2) or (5) a
                    final supplement to the form of prospectus included in such
                    registration statement relating to the Certificates and the
                    offering thereof. As filed, such final prospectus supplement
                    shall include all required information with respect to the
                    Certificates and the offering thereof and, except to the
                    extent the Representatives shall agree in writing to a
                    modification, shall be in all substantive respects in the
                    form furnished to you prior to the Execution Time or, to the
                    extent not completed at the Execution Time, shall contain
                    only such specific additional information and other changes
                    (beyond that contained in the Basic Prospectus and any
                    Preliminary Final Prospectus) as the Note Issuer has advised
                    you, prior to the Execution Time, will be included or made
                    therein.

                (2) The Note Issuer, the Notes and the Certificates meet the
                    requirements for the use of Form S-3 under the Act and the
                    Note Issuer has filed with the SEC a registration statement
                    (file number 333-74671) on such Form, including a basic
                    prospectus, for registration under the Act of the offering
                    and sale of the Certificates. The Note Issuer may have filed
                    one or more amendments thereto, including a Preliminary
                    Final Prospectus, each of which has previously been
                    furnished to you. The Note Issuer will next file with the
                    SEC either (x) a final prospectus supplement relating to the
                    Certificates in accordance with Rules 430A and 424(b)(1) or
                    (4), or (y) prior to the effectiveness of such registration
                    statement, an amendment to such registration statement,
                    including the form of final prospectus supplement. In the
                    case of clause (x), the Note Issuer has included in such
                    registration statement, as amended at the Effective Date,
                    all information (other than Rule 430A Information) required
                    by the Act and the rules thereunder to be included in the
                    Final Prospectus with respect to the Certificates and the
                    offering thereof. As filed, such final prospectus supplement
                    or such amendment and form of final prospectus supplement
                    shall contain all Rule 430A Information, together with all
                    other such required information, with respect to the
                    Certificates and the offering thereof and, except to the
                    extent the Representatives shall agree in writing to a
                    modification, shall be in all substantive respects in the
                    form furnished to you prior to the Execution Time or, to the
                    extent not completed at the Execution Time, shall contain
                    only such specific additional information and other changes
                    (beyond that contained in the Basic Prospectus and any
                    Preliminary Final Prospectus) as the


                                       3
<PAGE>   4
                    Note Issuer has advised you, prior to the Execution Time,
                    will be included or made therein.

                (ii) On the Effective Date, the Registration Statement did or
            will, and when the Final Prospectus is first filed (if required) in
            accordance with Rule 424(b) and on the Closing Date, the Final
            Prospectus (and any supplement thereto) will, comply in all material
            respects with the applicable requirements of the Act, the Securities
            Exchange Act of 1934 (the "Exchange Act") and the Trust Indenture
            Act of 1939 (the "Trust Indenture Act") and the respective rules
            thereunder; on the Effective Date, the Registration Statement did
            not or will not contain any untrue statement of a material fact or
            omit to state any material fact required to be stated therein or
            necessary in order to make the statements therein not misleading; on
            the Effective Date and on the Closing Date the Note Indenture and
            the Certificate Indenture did or will comply in all material
            respects with the requirements of the Trust Indenture Act and the
            rules and regulations thereunder; and, on the Effective Date, the
            Final Prospectus, if not filed pursuant to Rule 424(b), did not or
            will not, and on the date of any filing pursuant to Rule 424(b) and
            on the Closing Date, the Final Prospectus (together with any
            supplement thereto) will not, include any untrue statement of a
            material fact or omit to state a material fact necessary in order to
            make the statements therein, in the light of the circumstances under
            which they were made, not misleading; provided, however, that
            neither the Note Issuer nor the Company makes any representations or
            warranties as to (i) that part of the Registration Statement which
            shall constitute the Statements of Eligibility and Qualification
            (Forms T-1) under the Trust Indenture Act of the Note Trustee and
            the Certificate Trustee or (ii) the information contained in or
            omitted from the Registration Statement or the Final Prospectus (or
            any supplement thereto) in reliance upon and in conformity with
            information furnished in writing to the Note Issuer by or on behalf
            of any Underwriter through the Representatives specifically for
            inclusion in the Registration Statement or the Final Prospectus (or
            any supplement thereto). No stop order suspending the effectiveness
            of the Registration Statement has been issued and no proceedings for
            that purpose have been instituted.

                (iii) The terms which follow, when used in this Agreement, shall
            have the meanings indicated. The term "the Effective Date" shall
            mean each date that the Registration Statement and any
            post-effective amendment or amendments thereto became or become

            of Certificates pursuant to Rule 415 which does not commence
            promptly after the effective date of a registration statement, with
            the result that only information required pursuant to Rule 415 need
            be included in such registration statement at the effective date
            thereof with respect to the Certificates so offered. Whether the
            offering of the Certificates is a Non-Delayed Offering or a Delayed
            Offering shall be set forth in Schedule I hereto.

               3. Purchase and Sale. Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Trust
will sell to each Underwriter, and each Underwriter agrees, severally and not
jointly, to purchase from the Trust, at the


                                       5
<PAGE>   6
purchase price for each class of Certificates set forth in Schedule II hereto,
the respective principal amount of each class of Certificates set forth opposite
the name of each Underwriter on Schedule II hereto. Simultaneously with the
execution and delivery of this Agreement, and as a condition precedent to the
effectiveness of this Agreement, the Agencies will deliver to the Company, the
Note Issuer and the Representatives an executed copy of the certificate attached
hereto as Appendix A.

               4. Delivery and Payment. Delivery of and payment for the
Certificates shall be made at 9:00 AM Eastern Standard Time on July 29, 1999 (or
such later date not later than five business days after such specified date as
the Representatives shall designate), which date and time may be postponed by
agreement between the Representatives and the Note Issuer or as provided in
Section 9 hereof (such date and time of delivery and payment for the
Certificates being herein called the "Closing Date"). Delivery of the
Certificates shall be made to the Representatives for the respective accounts of
the several Underwriters against payment by the several Underwriters through the
Representatives of the purchase price thereof to the Trust by wire transfer of
immediately available funds in U.S. dollars. Delivery of the Certificates shall
be made at such location as the Representatives shall reasonably designate at
least one business day in advance of the Closing Date. The Certificates to be so
delivered shall be initially represented by Certificates registered in the name
of Cede & Co., as nominee of The Depository Trust Company ("DTC"). The interests
of beneficial owners of the Certificates will be represented by book entries on
the records of DTC and participating members thereof. Definitive Certificates
will be available only under limited circumstances described in the Final
Prospectus.

            The Trust will have the Certificates available for inspection,
checking and packaging by the Representatives in New York, New York, not later
than 1:00 PM on the business day prior to the Closing Date.

               5. Covenants.

            (a) Covenants of the Note Issuer. The Note Issuer covenants and
        agrees with the several Underwriters that:

                (i) The Note Issuer will use its best efforts to cause the
            Registration Statement, if not effective at the Execution Time, and
            any amendment thereto, to become effective. Prior to the termination
            of the offering of the Certificates, the Note Issuer will not file
            any amendment of the Registration Statement or supplement (including
            the Final Prospectus or any Preliminary Final Prospectus) to the
            Basic Prospectus unless the Note Issuer has furnished you a copy for
            your review prior to filing and will not file any such proposed
            amendment or supplement to which you reasonably object. Subject to
            the foregoing sentence, the Note Issuer will cause the Final
            Prospectus, properly completed in a form approved by you, and any
            supplement thereto to be filed with the SEC pursuant to the
            applicable paragraph of Rule 424(b) within the time period
            prescribed and will provide evidence satisfactory to the
            Representatives of such timely filing. The Note Issuer will promptly
            advise the Representatives (i) when the Registration


                                       6
<PAGE>   7
            Statement, if not effective at the Execution Time, and any amendment
            thereto, shall have become effective, (ii) when the Final
            Prospectus, and any supplement thereto, shall have been filed with
            the SEC pursuant to Rule 424(b), (iii) when, prior to termination of
            the offering of the Certificates, any amendment to the Registration
            Statement shall have been filed or become effective, (iv) of any
            request by the SEC for any amendment of the Registration Statement
            or supplement to the Final Prospectus or for any additional
            information, (v) of the issuance by the SEC of any stop order
            suspending the effectiveness of the Registration Statement or the
            institution or threatening of any proceeding for that purpose and
            (vi) of the receipt by the Note Issuer of any notification with
            respect to the suspension of the qualification of the Certificates
            for sale in any jurisdiction or the initiation or threatening of any
            proceeding for such purpose. The Note Issuer will use its best
            efforts to prevent the issuance of any such stop order and, if
            issued, to obtain as soon as possible the withdrawal thereof.

                (ii) If, at any time when a prospectus relating to the
            Certificates is required to be delivered under the Act, any event
            occurs as a result of which the Final Prospectus as then
            supplemented would include any untrue statement of a material fact
            or omit to state any material fact necessary to make the statements
            therein in the light of the circumstances under which they were made
            not misleading, or if it shall be necessary to amend the
            Registration Statement or supplement the Final Prospectus to comply
            with the Act or the Exchange Act or the respective rules thereunder,
            the Note Issuer promptly will (i) prepare and file with the SEC,
            subject to the second sentence of paragraph (a) of this Section 5,
            an amendment or supplement which will correct such statement or
            omission or effect such compliance and (ii) supply any supplemented
            Prospectus to you in such quantities as you may reasonably request.

                (iii) As soon as practicable, the Note Issuer will use its
            reasonable efforts to cause the Trust to make generally available to
            the Certificateholders and the Representatives an earnings statement
            or statements of the Trust which will satisfy the provisions of
            Section 11(a) of the Act and Rule 158 under the Act.

                (iv) The Note Issuer will furnish to the Representatives and
            counsel for the Underwriters, without charge, copies of the
            Registration Statement (including exhibits thereto) and, so long as
            delivery of a prospectus by an Underwriter or dealer may be required
            by the Act, as many copies of any Preliminary Final Prospectus and
            the Final Prospectus and any supplement thereto as the
            Representatives may reasonably request. The Note Issuer shall
            furnish or cause to be furnished to the Representatives copies of
            all reports on Form SR required by Rule 463 under the Act. The Note
            Issuer will pay the expenses of printing or other production of all
            documents relating to the offering.

                (v) The Note Issuer will arrange for the qualification of the
            Certificates for sale under the laws of such jurisdictions as the
            Representatives may


                                       7
<PAGE>   8
            designate, will maintain such qualifications in effect so long as
            required for the distribution of the Certificates and will arrange
            for the determination of the legality of the Certificates for
            purchase by institutional investors; provided, however, that in no
            event shall the Note Issuer be obligated to qualify to do business
            in any jurisdiction where it is not now so qualified or to take any
            action that would subject it to service of process in suits, other
            than those arising out of the offering or sale of the Certificates,
            in any jurisdiction where it is not now so subject.

                (vi) Until 90 days after the date hereof, the Note Issuer will
            not, without the written consent of the Representatives, offer, sell
            or contract to sell, or otherwise dispose of, directly or
            indirectly, or announce the offering of, any asset-backed securities
            of a trust or other special purpose vehicle (other than the Notes
            and the Certificates).

                (vii) For a period from the date of this Agreement until the
            retirement of the Certificates or until such time as the
            Underwriters shall cease to maintain a secondary market in the
            Certificates, whichever occurs first, the Note Issuer will deliver
            to the Representatives the annual statements of compliance and the
            annual independent auditor's servicing reports furnished to the Note
            Issuer or the Note Trustee pursuant to the Servicing Agreement or
            the Note Indenture, as applicable, as soon as such statements and
            reports are furnished to the Note Issuer or the Note Trustee.

                (viii) So long as any of the Certificates are outstanding, the
            Note Issuer will furnish to the Representatives (i) as soon as
            available, a copy of each report of the Note Issuer or the Trust
            filed with the SEC under the Exchange Act, or mailed to
            Certificateholders, (ii) a copy of any filings with the
            Massachusetts Department of Transportation and Energy ("DTE")
            pursuant to the Financing Order, including, but not limited to, any
            Advice Letters, and (iii) from time to time, any information
            concerning the Company, the Note Issuer or the Trust, as the
            Representatives may reasonably request.

                (ix) To the extent, if any, that any rating necessary to satisfy
            the condition set forth in Section 6(r) of this Agreement is
            conditioned upon the furnishing of documents or the taking of other
            actions by the Note Issuer on or after the Closing Date, the Note
            Issuer shall furnish such documents and take such other actions.

            (b) Covenants of the Company. The Company covenants and agrees with
        the several Underwriters that, to the extent that the Note Issuer has
        not already performed such act pursuant to Section 5(a):

                (i) The Company will use its best efforts to cause the
            Registration Statement, if not effective at the Execution Time, and
            any amendment thereto, to become effective. The Company will use its
            best efforts to prevent the issuance


                                       8
<PAGE>   9
            by the SEC of any stop order suspending the effectiveness of the
            Registration Statement and, if issued, to obtain as soon as possible
            the withdrawal thereof.

                (ii) The Company will cause the proceeds from the sale of the
            Transition Property to be applied for the purposes described in the
            Prospectus under the caption "Use of Proceeds."

                (iii) Until 90 days after the date hereof, the Company will not,
            without the written consent of the Representatives, offer, sell or
            contract to sell, or otherwise dispose of, directly or indirectly,
            or announce the offering of, any asset-backed securities of a trust
            or other special purpose vehicle (other than the Notes and the
            Certificates).

                (iv) So long as any of the Certificates are outstanding and the
            Company is the Servicer, the Company will furnish to the
            Representatives (i) as soon as available, a copy of each report of
            the Trust filed with the SEC under the Exchange Act, or mailed to
            Certificateholders, (ii) a copy of any filings with the DTE pursuant
            to the Financing Order, including, but not limited to, any Advice
            Letters, and (iii) from time to time, any information concerning the
            Company, the Note Issuer or the Trust, as the Representatives may
            reasonably request.

                (v) To the extent, if any, that any rating necessary to satisfy
            the condition set forth in Section 6(r) of this Agreement is
            conditioned upon the furnishing of documents or the taking of other
            actions by the Company on or after the Closing Date, the Company
            shall furnish such documents and take such other actions.

                (vi) If, at any time when a prospectus relating to the
            Certificates is required to be delivered under the Act, any event
            occurs as a result of which the Final Prospectus as then
            supplemented would include any untrue statement of a material fact
            or omit to state any material fact necessary to make the statements
            therein in the light of the circumstances under which they were made
            not misleading, or if it shall be necessary to amend the
            Registration Statement or supplement the Final Prospectus to comply
            with the Act or the Exchange Act or the respective rules thereunder,
            the Company at the Note Issuer's expense promptly will (i) prepare
            and file with the SEC, subject to the second sentence of paragraph
            (a) of this Section 5, an amendment or supplement which will correct
            such statement or omission or effect such compliance and (ii) supply
            any supplemented Prospectus to you in such quantities as you may
            reasonably request.

               6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Certificates shall be subject to
the accuracy of the representations and warranties on the part of the Note
Issuer and the Company contained herein as of the Execution Time and the Closing
Date and on the part of the Company contained in Article III of the Sale
Agreement and in Section 6.01 of the Servicing Agreement as of the Closing Date,

cates pursuant to the provisions hereof, to the performance by the Note Issuer,
the Company and the Trust of their obligations hereunder to be performed on or
prior to the Closing Date and to the following additional conditions:

            (a) If the Registration Statement has not become effective prior to
        the Execution Time, unless the Representatives agree in writing to a
        later time, the Registration Statement will become effective not later
        than (i) 6:00 PM Eastern Standard Time, on the date of determination of
        the public offering price, if such determination occurred at or prior to
        3:00 PM Eastern Standard Time on such date, or (ii) 12:00 Noon Eastern
        Standard Time on the business day following the day on which the public
        offering price was determined, if such determination occurred after 3:00
        PM Eastern Standard Time on such date; if filing of the Final
        Prospectus, or any supplement thereto, is required pursuant to Rule
        424(b), the Final Prospectus, and any such supplement, shall have been
        filed in the manner and within the time period required by Rule 424(b);
        and no stop order suspending the effectiveness of the Registration
        Statement shall have been issued and no proceedings for that purpose
        shall have been instituted or threatened.

            (b) The Representatives shall have received opinions of counsel for
        the Company, portions of which may be delivered by Ropes & Gray, outside

        in-house counsel for the Company, each dated the Closing Date, in form
        and substance reasonably satisfactory to the Representatives, to the
        effect that:

                (i) the Company is a validly existing corporation in good
            standing under the laws of the jurisdiction in which it is chartered
            or organized and has all requisite corporate power and authority to
            own its properties, conduct its business as presently conducted and
            execute, deliver and perform its obligations under this Agreement,
            the Sale Agreement and the Servicing Agreement;

                (ii) the Sale Agreement and the Servicing Agreement have been
            duly authorized, executed and delivered, and constitute legal, valid
            and binding instruments enforceable against the Company in
            accordance with their terms (subject, as to enforcement of remedies,
            to applicable bankruptcy, reorganization, insolvency, moratorium or
            other laws or equitable principles affecting creditors' rights
            generally from time to time in effect);

                (iii) to the knowledge of such counsel, there is no pending or
            threatened action, suit or proceeding before any court or
            governmental agency, authority or body or any arbitrator involving
            the Company or any of its subsidiaries of a character required to be
            disclosed in the Registration Statement which is not adequately
            disclosed in the Final Prospectus, and there is no franchise,
            contract or other document of a character required to be described
            in the Registration Statement or Final Prospectus, or to be filed as
            an exhibit, which is not described or filed as required;


                                       10
<PAGE>   11
                (iv) this Agreement has been duly authorized, executed and
            delivered by the Company;

                (v) no consent, approval, authorization or order of any court or
            governmental agency or body is required to be obtained by the
            Company for the consummation of the transactions contemplated
            herein, except such as have been obtained under the Statute, the DTE
            Regulations (as defined in Section 1.01 of the Servicing Agreement)
            and the Act and such as may be required under the blue sky laws of
            any jurisdiction in connection with the purchase and distribution of
            the Certificates by the Underwriters and such other approvals
            (specified in such opinion) as have been obtained;

                (vi) neither the execution and delivery of this Agreement, the
            Sale Agreement, the Servicing Agreement, the Administration
            Agreement nor the consummation of the transactions contemplated by
            this Agreement, the Sale Agreement, the Servicing Agreement or the
            Administration Agreement nor the fulfillment of the terms of this
            Agreement, the Sale Agreement, the Servicing Agreement or the
            Administration Agreement by the Company, will (A) conflict with,
            result in any breach of any of the terms or provisions of, or
            constitute (with or without notice or lapse of time) a default under
            the articles of incorporation, bylaws or other organizational
            documents of the Company, or conflict with or breach any of the
            material terms or provisions of, or constitute (with or without
            notice or lapse of time) a default under, any indenture, material
            agreement or other material instrument filed as an Exhibit to the
            Company's Annual Report on Form 10-K for the fiscal year ended
            December 31, 1998, (B) result in the creation or imposition of any
            lien upon any properties of the Company pursuant to the terms of any
            such indenture, agreement or other instrument (other than as
            contemplated by the Basic Documents and Section 1H(e) of the
            Statute), or (C) violate any Massachusetts or federal law or any
            order, rule or regulation applicable to the Company of any
            Massachusetts or federal court or regulatory body, administrative
            agency or other governmental instrumentality having jurisdiction
            over the Company, or any of its properties; and

                (vii) upon the delivery of the fully executed Sale Agreement to
            the Note Issuer and the payment of the purchase price of the
            Transition Property by the Note Issuer to the Seller pursuant to the
            Sale Agreement, then (A) the transfer of the Transition Property by
            the Seller to the Note Issuer pursuant to the Sale Agreement conveys
            the Seller's right, title and interest in the Transition Property to
            the Note Issuer and will be treated under the laws of The
            Commonwealth of Massachusetts as an absolute transfer of all of the
            Seller's right, title, and interest in the Transition Property,
            other than for federal and state income tax purposes, (B) such
            transfer of the Transition Property is perfected, (C) such transfer
            has priority over any other assignment of the Transition Property,
            and (D) the Transition Property is free and clear of all liens
            created prior to its transfer to the Note Issuer pursuant to the
            Sale Agreement.

    In rendering such opinion, such counsel may rely (A) as to matters involving
    the application of laws of any jurisdiction other than The Commonwealth of
    Massachusetts or the United States, to the extent deemed proper and
    specified in such opinion, upon the opinion of other counsel of good
    standing believed to be reliable and who are satisfactory to counsel for the
    Underwriters and (B) as to matters of fact, to the extent deemed proper, on
    certificates of responsible officers of the Company. References to the Final
    Prospectus in this paragraph (b) include any supplements thereto at the
    Closing Date.

        (c) The Representatives shall have received opinions of counsel for the
    Note Issuer, portions of which may be delivered by Ropes & Gray, outside
    counsel for the Note Issuer, and portions of which may be delivered by
    in-house counsel for the Note Issuer, and portions of which may be delivered
    by Richards, Layton & Finger, P.A., special Delaware counsel for the Note
    Issuer, each dated the Closing Date, in form and substance reasonably
    satisfactory to the Representatives, to the effect that:

            (i) the Note Issuer has been duly formed and is validly existing in
        good standing as a limited liability company under the laws of the State
        of Delaware, with all necessary limited liability company power and
        authority to execute, deliver and perform its obligations under this

        Indenture, the Note Purchase Agreement, the Administration Agreement and
        the Fee and Indemnity Agreement have been duly authorized, executed and

        Financing Order of a character required to be described in the
        Registration Statement or Final Prospectus, or to be filed as an
        exhibit, which is not described or filed as required; and the statements
        included in the Final Prospectus under the headings "Energy Deregulation
        and New Massachusetts Market Structure" (to the extent the Statute is
        described), "Description of the Transition Property," "The Note Issuer,"

        any material fact required to be stated therein or necessary to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading or that the Final Prospectus as of its

        under the blue sky laws of any jurisdiction in connection with the
        purchase and distribution of the Certificates by the Underwriters and
        such other approvals (specified in such opinion) as have been obtained;

            (ix) neither the execution and delivery of this Agreement, Sale
        Agreement, the Servicing Agreement, the Note Indenture, the Note
        Purchase Agreement, the Administration Agreement or the Fee and

        Liability Company Agreement of the Note Issuer, or conflict with or
        breach any of the material terms or provisions of, or constitute (with
        or without notice or lapse of time) a default under, any indenture,

        instrumentality having jurisdiction over the Note Issuer, or any of its
        properties;

            (x) Upon the giving of value by the Note Trustee to the Note Issuer
        with respect to the Collateral, (I) the Note Indenture creates in favor
        of the Note Trustee a security interest in the rights of the Note Issuer
        in the Collateral, (II) such security interest is valid against the Note
        Issuer (subject to the rights of any third parties holding security
        interests in such Collateral perfected in the manner described in
        Sections 1H(d) and (e) of the Statute), and has attached and (III) such
        security interest is perfected; and

        Investment Company Act of 1940, as amended.

    In rendering such opinion, such counsel may rely (A) as to matters involving
    the application of laws of any jurisdiction other than The Commonwealth of
    Massachusetts, the State of Delaware or the United States, to the extent
    deemed proper and specified in such opinion, upon the opinion of other
    counsel of good standing believed to be reliable and who are satisfactory to
    counsel for the Underwriters and (B) as to matters of fact, to the extent
    deemed proper, on certificates of responsible officers of the Note Issuer
    and public officials. References to the Final Prospectus in this paragraph
    (c) include any supplements thereto at the Closing Date.

        (k) At the Closing Date, PricewaterhouseCoopers LLP shall have furnished
    to the Representatives (i) a letter or letters (which may refer to letters
    previously delivered to one or more of the Representatives), dated as of the
    Closing Date, in form and substance satisfactory to the Representatives,
    confirming that they are independent accountants within the meaning of the
    Act and the Exchange Act and the respective applicable published rules and
    regulations thereunder and stating in effect that they have performed
    certain specified procedures as a result of which they determined that
    certain information of an accounting, financial or statistical nature (which
    is limited to accounting, financial or statistical information derived from
    the general accounting records of the Company and the Note Issuer) set forth
    in the Registration Statement and the Final Prospectus, including
    information specified by the Underwriters and set forth under the captions
    "Prospectus Summary," "Description of the Transition Property," "The Seller
    and Servicer," "Description of the Notes" and "Description of the

    the Company and the Note Issuer, excluding any questions of legal
    interpretation, and (ii) the opinion or certificate, dated as of the Closing
    Date, in form and substance satisfactory to the Representatives, satisfying
    the requirements of Section 2.10(7) of the Note Indenture.

        References to the Final Prospectus in this paragraph (k) include any
    supplement thereto at the date of the letter.

        In addition, at the Execution Time, PricewaterhouseCoopers LLP shall
    have furnished to the Representatives a letter or letters, dated as of the

    to the effect set forth above.

        (l) Subsequent to the Execution Time or, if earlier, the dates as of
    which information is given in the Registration Statement (exclusive of any
    amendment thereof) and the Final Prospectus (exclusive of any supplement
    thereto), there shall not have been any change, or any development involving
    a prospective change, in or affecting either (i) the business, properties or
    financial condition of the Company or the Note Issuer or (ii) the Transition
    Property, the Notes, the Certificates, the Financing Order or the Statute,
    the effect of which is, in the judgment of the Representatives, so material
    and adverse as to make it impractical or inadvisable to proceed with the
    offering or delivery of the Notes


                                       22
<PAGE>   23
    or the Certificates as contemplated by the Registration Statement (exclusive
    of any amendment thereof) and the Final Prospectus (exclusive of any
    supplement thereto).

        (m) The Representatives shall have received on the Closing Date an
    opinion letter or letters of Ropes & Gray, counsel to the Company and the
    Note Issuer, dated the Closing Date, in form and substance reasonably
    satisfactory to the Representatives, (i) with respect to the
    characterization of the transfer of the Transition Property by the Company
    to the Note Issuer as a "true sale" for bankruptcy purposes and (ii) to the
    effect that a court would not order the substantive consolidation of the
    assets and liabilities of the Note Issuer with those of the Company in the
    event of a bankruptcy, reorganization or other insolvency proceeding
    involving the Company.

        (n) The Representatives shall have received on the Closing Date an
    opinion letter of Palmer & Dodge LLP, special counsel to the Agencies and
    the Trust, dated the Closing Date, in form and substance reasonably
    satisfactory to the Representatives, to the effect that a court would not
    order the substantive consolidation of the assets and liabilities of the
    Agencies with those of the Trust.

        (o) The Representatives shall have received on the Closing Date an
    opinion letter or letters of counsel for the Company, portions of which may

    of which may be delivered by in-house counsel for the Company, each dated
    the Closing Date, in form and substance reasonably satisfactory to the
    Representatives, to the effect that: (i) the Financing Order has been duly
    issued and authorized by the DTE and the Financing Order, giving effect to
    the Issuance Advice Letter, is effective; (ii) in reliance on the opinion of
    Krokidas & Bluestein LLP that the Certificates are "electric rate reduction
    bonds" under Section 1H(a) of the Statute, as of the issuance of the
    Certificates, the Certificates are entitled to the protections provided in
    Sections 1H(b)(3) and 1H(c)(4) of the Statute; (iii) the Financing Order is
    no longer subject to appeal by any person in state courts of The
    Commonwealth of Massachusetts; and (iv) the Servicer is authorized to file
    periodic RTC Charge adjustments to the extent necessary to ensure the timely
    recovery of revenues sufficient to provide for the payment of an amount
    equal to the sum of the periodic RRB payment requirements for the upcoming
    year, which includes indemnity obligations under the Basic Documents.

        (p) The Representatives shall have received on the Closing Date an
    opinion letter or letters of Palmer & Dodge LLP, special counsel for the
    Agencies and the Trust, dated the Closing Date, in form and substance
    reasonably satisfactory to the Representatives, to the effect that any state
    action (whether by legislative, DTE, citizen initiative or otherwise) to
    revoke or limit the Financing Order, the Issuance Advice Letter, the
    Transition Property or the RTC Charge in a manner which would substantially
    impair the rights of Certificateholders would be subject to a successful
    constitutional contracts clause defense.


                                       23
<PAGE>   24
        (q) The Representatives shall have received on the Closing Date an
    opinion letter or letters of Richards, Layton & Finger, P.A., special
    Delaware counsel to the Note Issuer, dated the Closing Date, in form and
    substance reasonably satisfactory to the Representatives, to the effect
    that: (i) if properly presented to a Delaware court, a Delaware court
    applying Delaware law, would conclude that (x) in order for a person to file
    a voluntary bankruptcy petition on behalf of the Note Issuer, the
    affirmative vote of the Note Issuer's Sole Member and the affirmative vote
    of all of the Directors (including the Independent Directors), as provided
    in Section 2.07(ii) of the LLC Agreement of the Note Issuer, is required,
    and (y) such provision, contained in Section 2.07(ii) of the LLC Agreement,
    that requires the affirmative vote of the Note Issuer's Sole Member and the
    affirmative vote of all of the Directors (including the Independent
    Directors) in order for a person to file a voluntary bankruptcy petition on
    behalf of the Note Issuer, constitutes a legal, valid and binding agreement
    of the Sole Member and is enforceable against the Sole Member, in accordance
    with its terms; and (ii) the LLC Agreement constitutes a legal, valid and
    binding agreement of the Sole Member thereunder, and is enforceable against
    the Sole Member in accordance with its terms.

        (r) The Notes and the Certificates shall have been rated in the highest
    long-term rating category by each of the Rating Agencies.

        (s) On or prior to the Closing Date, the Note Issuer shall have
    delivered to the Representatives evidence, in form and substance reasonably
    satisfactory to the Representatives, that appropriate filings have been or
    are being made in accordance with the Statute and other applicable law
    reflecting the grant of a security interest by the Note Issuer in the
    Collateral to the Note Trustee.

        (t) On or prior to the Closing Date, the Note Issuer shall have
    delivered to the Representatives evidence, in form and substance
    satisfactory to the Representatives, of the DTE's issuance of the Financing
    Order relating to the Transition Property and the Issuance Advice Letter.

        (u) Prior to the Closing Date, the Note Issuer, the Company and the
    Trust shall have furnished to the Representatives such further information,
    certificates, opinions and documents as the Representatives may reasonably
    request.

               If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to the Note Issuer
and the Trust in writing or by telephone or electronic mail confirmed in
writing.

               The documents required to be delivered by this Section 6 shall be
delivered at the office of Ropes & Gray, Boston, Massachusetts, on the Closing
Date.


                                       24

               7. Expenses. Upon the sale of the Certificates, the Note Issuer
will pay or cause to be paid all costs and expenses incident to the performance
of the obligations of the Company, the Note Issuer, the Trust and the
Underwriters hereunder and the Agencies under the Basic Documents, including,
without limiting the generality of the foregoing, all costs, taxes and expenses
incident to the issue and delivery of the Certificates to the Underwriters, all
fees, disbursements and expenses of the Company's, the Note Issuer's, the
Trust's, the Agencies' and the Underwriters' counsel and accountants, all costs
and expenses incident to the preparation, printing and filing of the
Registration Statement (including all exhibits thereto), any preliminary
prospectus, the Basic Prospectus, any Preliminary Final Prospectus, the Final
Prospectus and any amendments thereof or supplements thereto, all costs and
expenses incurred in connection with blue sky qualifications, examining the
legality of the Certificates for the investment and the rating of the
Certificates, all costs and expenses of the Note Trustee, the Certificate
Trustee and the Delaware Trustee, all costs and expenses incurred in the
acquisition or preparation of documents required to be delivered by the Company,
the Note Issuer, the Trust or the Agencies in connection with the closing of the
transactions contemplated hereby, all costs and expenses required in connection
with any filing with the National Association of Securities Dealers in
connection with the transactions contemplated hereby, and all costs and expenses
of the printing and distribution of all documents in connection with the
Certificates.

        If the sale of the Certificates provided for herein is not consummated
because any condition to the obligations of the Underwriters set forth in
Section 6 hereof is not satisfied, because of any termination pursuant to
Section 10 hereof or because of any refusal, inability or failure on the part of
the Company, the Note Issuer or the Trust to perform any agreement herein or
comply with any provision hereof other than by reason of a default (including
under Section 9) by any of the Underwriters, the Company and the Note Issuer
will, jointly and severally, reimburse the Underwriters upon demand for all
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by the Underwriters in connection with the
proposed purchase and sale of the Certificates.

               8. Indemnification and Contribution.

        (a) The Company and the Note Issuer will, jointly and severally,
    indemnify and hold harmless each Underwriter, the Trust and the Agencies,
    the directors, officers, members, employees and agents of each Underwriter,
    the Trust and the Agencies and each person who controls any Underwriter, the
    Trust and the Agencies within the meaning of either the Act or the Exchange
    Act against any and all losses, claims, damages or liabilities, joint or
    several, to which they or any of them may become subject under the Act, the
    Exchange Act or other Federal or state statutory law or regulation, at
    common law or otherwise, insofar as such losses, claims, damages or
    liabilities (or actions in respect thereof) arise out of or are based upon
    any untrue statement or alleged untrue statement of a material fact
    contained in the Registration Statement for the registration of the
    Certificates as originally filed or in any amendment thereof, or any
    omission or alleged omission to state therein a material fact required to be
    stated therein or necessary to make the statements therein not misleading,
    any untrue statement or alleged untrue statement of a material fact
    contained in the Basic Prospectus, any


                                       25
<PAGE>   26
    Preliminary Final Prospectus or the Final Prospectus, or in any amendment
    thereof or supplement thereto, or arise out of or are based upon the
    omission or alleged omission to state therein a material fact required to be
    stated therein or necessary to make the statements therein, in light of the
    circumstances under which they were made, not misleading, and will reimburse
    each such indemnified party, as incurred, for any legal or other expenses
    reasonably incurred by them in connection with investigating or defending
    any such loss, claim, damage, liability or action; provided, however, that
    neither the Company nor the Note Issuer will be liable in any such case to
    the extent that any such loss, claim, damage or liability arises out of or
    is based upon any such untrue statement or alleged untrue statement or
    omission or alleged omission made therein in reliance upon and in conformity
    with written information furnished to the Note Issuer or the Company by or
    on behalf of any Underwriter through the Representatives specifically for
    inclusion therein. This indemnity agreement will be in addition to any
    liability which the Company and the Note Issuer may otherwise have.

        (b) Each Underwriter severally agrees to indemnify and hold harmless the
    Company, the Note Issuer, the Trust and the Agencies, each of their
    directors, each of their officers (if any) who signs the Registration
    Statement, and each person who controls the Company or the Note Issuer
    within the meaning of either the Act or the Exchange Act, to the same extent
    as the foregoing indemnity from the Company and the Note Issuer to each
    Underwriter, but only with reference to written information relating to such
    Underwriter furnished to the Note Issuer or the Company by or on behalf of
    such Underwriter through the Representatives specifically for inclusion in
    the documents referred to in the foregoing indemnity. This indemnity
    agreement will be in addition to any liability which any Underwriter may
    otherwise have. The Note Issuer, the Company and the Agencies acknowledge
    that the statements set forth in the last paragraph of the cover page, under
    the heading "Underwriting" or "Plan of Distribution" in any Preliminary
    Final Prospectus or the Final Prospectus constitute the only information
    furnished in writing by or on behalf of the several Underwriters for
    inclusion in the documents referred to in the foregoing indemnity, and you,
    as the Representatives, confirm that such statements are correct.

        (c) Promptly after receipt by an indemnified party under this Section 8
    of notice of the commencement of any action, such indemnified party will, if
    a claim in respect thereof is to be made against the indemnifying party
    under this Section 8, notify the indemnifying party in writing of the
    commencement thereof; but the failure so to notify the indemnifying party
    (i) will not relieve it from liability under paragraph (a) or (b) above
    unless and to the extent it did not otherwise learn of such action and such
    failure results in the forfeiture by the indemnifying party of substantial
    rights and defenses and (ii) will not, in any event, relieve the
    indemnifying party from any obligations to any indemnified party other than
    the indemnification obligation provided in paragraph (a) or (b) above. The
    indemnifying party shall be entitled to appoint counsel of the indemnifying
    party's choice at the indemnifying party's expense to represent the
    indemnified party in any action for which indemnification is sought (in
    which case the indemnifying party shall not thereafter be responsible for
    the fees and expenses of any


                                       26
<PAGE>   27
    separate counsel retained by the indemnified party or parties except as set
    forth below); provided, however, that such counsel shall be reasonably
    satisfactory to the indemnified party. Notwithstanding the indemnifying
    party's election to appoint counsel to represent the indemnified party in an
    action, the indemnified party shall have the right to employ separate
    counsel (including local counsel), and the indemnifying party shall bear the
    reasonable fees, costs and expenses of such separate counsel if (i) the use
    of counsel chosen by the indemnifying party to represent the indemnified
    party would present such counsel with a conflict of interest, (ii) the
    actual or potential defendants in, or targets of, any such action include
    both the indemnified party and the indemnifying party and the indemnified
    party shall have reasonably concluded that there may be legal defenses
    available to it and/or other indemnified parties which are different from or
    additional to those available to the indemnifying party, (iii) the
    indemnifying party shall not have employed counsel reasonably satisfactory
    to the indemnified party to represent the indemnified party within a
    reasonable time after notice of the institution of such action or (iv) the
    indemnifying party shall authorize the indemnified party to employ separate
    counsel at the expense of the indemnifying party. An indemnifying party will
    not, without the prior written consent of the indemnified parties, settle or
    compromise or consent to the entry of any judgment with respect to any
    pending or threatened claim, action, suit or proceeding in respect of which
    indemnification or contribution may be sought hereunder (whether or not the
    indemnified parties are actual or potential parties to such claim or action)
    unless such settlement, compromise or consent includes an unconditional
    release of each indemnified party from all liability arising out of such
    claim, action, suit or proceeding.

        (d) In the event that the indemnity provided in paragraph (a) or (b) of
    this Section 8 is unavailable to or insufficient to hold harmless an
    indemnified party for any reason, the Company, the Note Issuer and the
    Underwriters agree to contribute to the aggregate losses, claims, damages
    and liabilities (including legal or other expenses reasonably incurred in
    connection with investigating or defending same) (collectively "Losses") to
    which the Company, the Note Issuer and one or more of the Underwriters may
    be subject in such proportion as is appropriate to reflect the relative
    benefits received by the Company, Note Issuer and the Underwriters,
    respectively, from the offering of the Certificates and the Notes; provided,
    however, that in no case shall any Underwriter (except as may be provided in
    any agreement among underwriters relating to the offering of the
    Certificates) be responsible for any amount in excess of the underwriting
    discount or commission applicable to the Certificates purchased by such
    Underwriter hereunder. If the allocation provided by the immediately
    preceding sentence is unavailable for any reason, the Company, the Note
    Issuer and the Underwriters shall contribute in such proportion as is
    appropriate to reflect not only such relative benefits but also the relative
    fault of the Company, the Note Issuer and of the Underwriters in connection
    with the statements or omissions which resulted in such Losses as well as
    any other relevant equitable considerations. Benefits received by the Note
    Issuer shall be deemed to be equal to the total net proceeds from the
    offering (before deducting expenses) of the Certificates (which shall be
    equal to the net proceeds from the sale of the Notes to the Trust (before
    deducting expenses)), and benefits received by the Underwriters shall be


                                       27
<PAGE>   28
    deemed to be equal to the total underwriting discounts and commissions, in
    each case as set forth on the cover page of the Final Prospectus. Relative
    fault shall be determined by reference to whether any alleged untrue
    statement or omission relates to information provided by the Company, the
    Note Issuer or the Underwriters. The Company, the Note Issuer and the
    Underwriters agree that it would not be just and equitable if contribution
    were determined by pro rata allocation or any other method of allocation
    which does not take account of the equitable considerations referred to
    above. Notwithstanding the provisions of this paragraph, no person guilty of
    fraudulent misrepresentation (within the meaning of Section 11(f) of the
    Act) shall be entitled to contribution from any person who was not guilty of
    such fraudulent misrepresentation. For purposes of this Section 8, each
    person who controls an Underwriter within the meaning of either the Act or
    the Exchange Act and each director, officer, employee and agent of an
    Underwriter shall have the same rights to contribution as such Underwriter,
    and each person who controls the Note Issuer or the Company within the
    meaning of either the Act or the Exchange Act, each officer of the Note
    Issuer or the Company who shall have signed the Registration Statement and
    each director of the Note Issuer or the Company shall have the same rights
    to contribution as the Note Issuer or the Company, subject in each case to
    the applicable terms and conditions of this paragraph. The Underwriters'
    obligations in this paragraph to contribute are several in proportion to
    their respective underwriting obligations and not joint.

               9. Default by an Underwriter. If any one or more Underwriters
shall fail to purchase and pay for any of the Certificates agreed to be
purchased by such Underwriter or Underwriters hereunder the Representatives may
in their discretion arrange for the Underwriters or another party or other
parties to purchase such Certificates on the terms contained herein. If within
36 hours after such default by any Underwriter the Representatives do not
arrange for the purchase of such Certificates, the nondefaulting Underwriters
shall be obligated severally to take up and pay for (in the respective
proportions which the amount of Certificates set forth opposite the names of all
the remaining Underwriters) the Certificates which the defaulting Underwriter or
Underwriters agreed but failed to purchase; provided, however, that in the event
that the aggregate amount of Certificates which the defaulting Underwriter or
Underwriters agreed but failed to purchase shall exceed 10% of the aggregate
amount of Certificates set forth in Schedule II hereto, the nondefaulting
Underwriters shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Certificates, and if such nondefaulting
Underwriters do not purchase all the Certificates, this Agreement will terminate
without liability to any nondefaulting Underwriter, the Note Issuer or the
Company. In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
seven days, as the Representatives shall determine in order that the required
changes in the Registration Statement and the Final Prospectus or in any other
documents or arrangements may be effected. Nothing contained in this Agreement

the Agencies prior to delivery of and payment for the Certificates, if prior to
such time there shall have occurred (i) any change, or any development involving
a prospective change, in or affecting (A) the business, properties or financial
condition of the Company or the Note Issuer, (B) the Transition Property, the
Notes, the Certificates, the Financing Order or the Statute, the effect of
which, in the judgment of the Representatives, materially impairs the investment
quality of the Certificates or makes it impractical or inadvisable to market the
Certificates; (ii) a suspension or material limitation in trading in securities
generally on the New York Stock Exchange; (iii) a suspension or material
limitation in trading in the securities of the Company; (iv) a general
moratorium on commercial banking activities shall have been declared either by
Federal, New York state or Massachusetts state authorities or (v) any outbreak
or escalation of hostilities involving the United States or the declaration by
the United States of a national emergency or war the effect of which on
financial markets is such as to make it, in the judgment of the Representatives,
impracticable or inadvisable to proceed with the offering or delivery of the
Certificates as contemplated by the Final Prospectus (exclusive of any
supplement thereto).

               11. Representations and Indemnities to Survive. The respective

         respect to the initial Payment Date or, if no payment has yet been
         made, interest on the outstanding principal balance will accrue from
         and including the Issuance Date to, but excluding, that Payment Date.

         Section 2.02. Form. The Notes and the Note Trustee's certificate of
authentication shall be in substantially the forms set forth in Exhibit B, with
such appropriate insertions, omissions, substitutions and other variations as
are required or permitted by this Note Indenture and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may, consistently herewith, be determined by the officers executing
such Notes, as evidenced by their execution of such Notes. Any portion of the
text of any Note may be set forth on the reverse thereof, with an appropriate
reference thereto on the face of the Note.

         The Notes shall be typewritten, printed, lithographed or engraved or
produced by any combination of these methods (with or without steel engraved
borders), all as determined by the officers executing such Notes, as evidenced
by their execution of such Notes.

         The terms of the Notes set forth in Exhibit B are part of the terms of
this Note Indenture.

         Section 2.03. Execution, Authentication and Delivery. The Notes shall
be executed on behalf of the Note Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Notes may be manual or
facsimile.

         Notes bearing the manual or facsimile signature of individuals who were
at any time Authorized Officers of the Note Issuer shall bind the Note Issuer,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Notes or did not hold
such offices at the date of such Notes.

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

         No Note shall be entitled to any benefit under this Note 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 Note Trustee by the manual signature of one of its authorized
signatories, 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. Temporary Notes. Pending the preparation of definitive
Notes, the Note Issuer may execute, and upon receipt of an Issuer Order the Note
Trustee shall authenticate and deliver, temporary Notes which are printed,
lithographed, typewritten, mimeographed or otherwise produced, of the tenor of
the definitive Notes in lieu of which they are issued and with such variations
not inconsistent with the terms of this Note Indenture as the officers executing
such Notes may determine, as evidenced by their execution of such Notes.

         If temporary Notes are issued, the Note Issuer will cause definitive
Notes to be prepared without unreasonable delay. After the preparation of
definitive Notes, the temporary Notes shall be exchangeable for definitive Notes
upon surrender of the temporary Notes at the office or agency of the Note Issuer
to be maintained as provided in Section 3.02, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Notes, the Note Issuer
shall execute and the Note Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Notes of Minimum Denominations.
Until so exchanged, the temporary Notes shall in all respects be entitled to the
same benefits under this Note Indenture as definitive Notes.

         Section 2.05. Registration; Registration of Transfer and Exchange. The
Note Issuer shall cause to be kept a register (the "Note Register") in which,
subject to such reasonable regulations as it may prescribe, the Note Issuer
shall provide for the registration of Notes and the registration of transfers of
Notes. The Note Trustee shall be "Note Registrar" for the purpose of registering
Notes and transfers of Notes as herein provided. Upon any resignation of any
Note Registrar, the Note Issuer shall promptly appoint a successor or, if it
elects not to make such an appointment, assume the duties of Note Registrar.

         If a Person other than the Note Trustee is appointed by the Note Issuer
as Note Registrar, the Note Issuer will give the Note Trustee prompt written
notice of the appointment of such Note Registrar and of the location, and any
change in the location, of the Note Register, and the Note Trustee shall have
the right to inspect the Note Register at all reasonable times and to obtain
copies thereof, and the Note Trustee shall have the right to rely upon a
certificate executed on behalf of the Note Registrar by a Responsible Officer
thereof as to the names and addresses of the Holders of the Notes and the
principal amounts and number of such Notes.

         Upon surrender for registration of transfer of any Note at the office
or agency of the Note Issuer to be maintained as provided in Section 3.02, the
Note Issuer shall execute, and the Note Trustee shall authenticate and the
Noteholder shall obtain from the Note Trustee, in the name of the designated
transferee or transferees, one or more new Notes in any Minimum Denominations,
of a like Class and aggregate principal amount.

         At the option of the Holder, Notes may be exchanged for other Notes in
any Minimum Denominations, of a like Class and aggregate principal amount, upon
surrender of the Notes to be exchanged at such office or agency. Whenever any
Notes are so surrendered for exchange, the Note Issuer shall execute, and the
Note Trustee shall authenticate and the Noteholder shall obtain from the Note
Trustee, the Notes which the Noteholder making the exchange is entitled to
receive.

                                       15
<PAGE>   22
         All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Note Issuer, evidencing the same debt, and
entitled to the same benefits under this Note Indenture, as the Notes
surrendered upon such registration of transfer or exchange.

         Every Note presented or surrendered for registration of transfer or
exchange shall be duly endorsed by, or be accompanied by (a) a written
instrument of transfer in form satisfactory to the Note Trustee duly executed by
the Holder thereof or such Holder's attorney duly authorized in writing, with
such signature guaranteed by an institution which is a member of one of the
following recognized Signature Guaranty Programs: (i) The Securities Transfer
Agent Medallion Program (STAMP); (ii) The New York Stock Exchange Medallion
Program (MSP); (iii) The Stock Exchange Medallion Program (SEMP); or (iv) in
such other guarantee program acceptable to the Note Trustee, and (b) such other
documents as the Note Trustee may require.

         No service charge shall be made to a Holder for any registration of
transfer or exchange of Notes, but the Note 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 not involving any transfer.

         The preceding provisions of this Section notwithstanding, the Note
Issuer shall not be required to make and the Note Registrar need not register
transfers or exchanges of Notes selected for redemption or of any Note for a
period of 15 days preceding the due date for any payment with respect to the
Note.

         Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. If (i) any
mutilated Note is surrendered to the Note Trustee, or the Note Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any Note, and
(ii) there is delivered to the Note Trustee such security or indemnity as may be
required by it to hold the Note Issuer and the Note Trustee harmless, then, in
the absence of notice to the Note Issuer, the Note Registrar or the Note Trustee
that such Note has been acquired by a protected purchaser, the Note Issuer shall
execute and, upon its request, the Note Trustee shall authenticate and deliver,
in exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Note, a replacement Note of like Class, tenor and principal amount, bearing a
number not contemporaneously outstanding; provided, however, that if any such
destroyed, lost or stolen Note, but not a mutilated Note, shall have become or
within seven days shall be due and payable, or shall have been called for
redemption, instead of issuing a replacement Note, the Note Issuer may pay such
destroyed, lost or stolen Note when so due or payable or upon the Optional
Redemption Date or Mandatory Redemption Date, as applicable, without surrender
thereof. If, after the delivery of such replacement Note or payment of a
destroyed, lost or stolen Note pursuant to the proviso to the preceding
sentence, a protected purchaser of the original Note in lieu of which such
replacement Note was issued presents for payment such original Note, the Note
Issuer and the Note Trustee shall be entitled to recover such replacement Note
(or such payment) from the Person to whom it was delivered or any Person taking
such replacement Note from such Person to whom such replacement Note was
delivered or any assignee of such Person, except a protected purchaser, and
shall be entitled to recover upon the security or indemnity provided therefor to
the extent of any loss, damage, cost or expense incurred by the Note Issuer or
the Note Trustee in connection therewith.

                                       16
<PAGE>   23
         Upon the issuance of any replacement Note under this Section, the Note
Issuer may require the payment by the Holder of such Note of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the Note Trustee) connected therewith.

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

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

         Section 2.07. Persons Deemed Owner. Prior to due presentment for
registration of transfer of any Note, the Note Issuer, the Note Trustee and any
agent of the Note Issuer or the Note Trustee may treat the Person in whose name
any Note is registered (as of the day of determination) 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 Note Issuer, the Note Trustee nor any agent of the Note Issuer
or the Note Trustee shall be affected by notice to the contrary.

         Section 2.08. Payment of Principal and Interest; Interest on Overdue
Principal; Principal and Interest Rights Preserved.

         (a) Any installment of interest or principal payable on any Note which
is punctually paid or duly provided for by the Note Issuer on the applicable
Payment Date shall be paid to the Person in whose name such Note (or one or more
Predecessor Notes) is registered on the Record Date for such Payment Date, by
check mailed first-class, postage prepaid to such Person's address as it appears
on the Note Register on such Record Date, except that with respect to Notes
registered on the Record Date in the name of the Certificate Trustee payments
will be made by wire transfer in immediately available funds to the account
designated by the Certificate Trustee and except for the final installment of
principal payable with respect to such Note on a Payment Date which shall be

undelivered shall be held in accordance with Section 3.03 hereof.

         (b) The principal of each Note of each Class shall be paid, to the
extent funds are available therefor in the Collection Account, in installments
on each Payment Date specified in Section 2.01. Notwithstanding the foregoing,
the entire unpaid principal amount of the Notes shall be due and payable, if not
previously paid, on the date on which an Event of Default shall have occurred
and be continuing, if the Note Trustee or the Holders of the Notes representing
not less than a majority of the Outstanding Amount of the Notes have declared
the Notes to be immediately due and payable in the manner provided in Section
5.02. In such event, all payments of principal on the Notes shall be made pro
rata. The Note Trustee shall notify the Person in whose name a Note is
registered at the close of business on the Record Date preceding


                                       17
<PAGE>   24
the Payment Date on which the Note Issuer expects that the final installment of
principal of and interest on such Note will be paid. Such notice shall be mailed
no later than five days prior to such final Payment Date and shall specify that
such final installment will be payable only upon presentation and surrender of
such Note and shall specify the place where such Note may be presented and
surrendered for payment of such installment. Notices in connection with
redemptions of Notes shall be mailed to Noteholders as provided in Section
10.02.

         (c) If the Note Issuer defaults in a payment of interest on the Notes
when due, the Note Issuer shall be required to pay such defaulted interest (plus
interest on such defaulted interest at the applicable Note Interest Rate to the
extent lawful) to the Persons who are Noteholders on a subsequent special record
date, which date shall be at least five Business Days prior to the payment date.
The Note Issuer shall fix or cause to be fixed any such special record date and
payment date, and, at least 20 days before any such special record date, the
Note Issuer shall mail to each affected Noteholder a notice that states the
special record date, the payment date and the amount of defaulted interest (plus
interest on such defaulted interest) to be paid.

         Section 2.09. Cancellation. All Notes surrendered for payment,
registration of transfer, exchange or redemption shall, if surrendered to any
Person other than the Note Trustee, be delivered to the Note Trustee and shall
be promptly cancelled by the Note Trustee. The Note Issuer may at any time
deliver to the Note Trustee for cancellation any Notes previously authenticated
and delivered hereunder which the Note Issuer may have acquired in any manner
whatsoever, and all Notes so delivered shall be promptly cancelled by the Note
Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes
cancelled as provided in this Section, except as expressly permitted by this
Note Indenture. All cancelled Notes may be held or disposed of by the Note
Trustee in accordance with its standard retention or disposal policy as in
effect at the time.

                  statement filed with respect to such first priority lien shall

         Charge are sufficient to pay (a) assumed Operating Expenses when

         Section 3.01. Payment of Principal and Interest. The Note Issuer will
duly and punctually pay the principal of and interest on the Notes in accordance
with the terms of the Notes and this Note Indenture. Amounts properly withheld

Note Trustee of the location, and of any change in the location, of any such
office or agency. If at any time the Note Issuer shall fail to maintain any such
office or agency or shall fail to furnish the Note Trustee with the address

         The Note Issuer will cause each Paying Agent other than the Note
Trustee to execute and deliver to the Note Trustee an instrument in which such
Paying Agent shall agree with the Note Trustee (and if the Note Trustee acts as
Paying Agent, it hereby so agrees), subject to the provisions of this Section,
that such Paying Agent will:

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

                  (ii) give the Note Trustee and the Certificate Trustee notice
         of any Default by the Note Issuer (or any other obligor upon the Notes)
         of which it has actual knowledge in the making of any payment required
         to be made with respect to the Notes;

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

                  (iv) immediately resign as a Paying Agent and forthwith pay to
         the Note Trustee all sums held by it in trust for the payment of Notes
         if at any time it ceases to meet the standards required to be met by a
         Paying Agent at the time of its appointment; and

                  (v) comply with all requirements of the Code with respect to
         the withholding from any payments made by it on any Notes of any
         applicable withholding taxes imposed thereon and with respect to any
         applicable reporting requirements in connection therewith.

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

         Subject to applicable laws with respect to escheat of funds, any money
held by the Note Trustee or any Paying Agent in trust for the payment of any
amount due with respect to any Note and remaining unclaimed for two years after
such amount has become due and payable shall be discharged from such trust and
be paid to the Note Issuer on Issuer Request; and, subject to Section 11.16, the
Holder of such Note shall thereafter, as an unsecured general creditor, look
only to the Note Issuer for payment thereof (but only to the extent of the
amounts so paid to the Note Issuer), and all liability of the Note Trustee or
such Paying Agent with respect to such trust money shall thereupon cease;
provided, however, that the Note Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Note 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 of New York, notice that such

                                       25
<PAGE>   32
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 will be repaid to the Note Issuer. The Note
Trustee may also adopt and employ, at the expense of the Note Issuer, any other
reasonable means of notification of such repayment (including mailing notice of
such repayment to Holders whose Notes have been called but have not been
surrendered for redemption or whose right to or interest in moneys due and
payable but not claimed is determinable from the records of the Note Trustee or
of any Paying Agent, at the last address of record for each such Holder).

         Section 3.04. Existence. The Note Issuer will keep in full effect its
existence, rights and franchises as a limited liability company under the laws
of the State of Delaware (unless, subject to the provisions of Section 3.10
hereof, it becomes, or any successor Note Issuer hereunder is or becomes,
organized under the laws of any other State or of the United States of America,
in which case the Note Issuer will keep in full effect its existence, rights and
franchises under the laws of such other jurisdiction) and will obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Note Indenture, the Notes, the Collateral and each other
instrument or agreement included in the Collateral.

         Section 3.05. Protection of Collateral. The Note Issuer will from time
to time execute and deliver all such supplements and amendments hereto and all
such filings with the DTE pursuant to the Statute, financing statements,
continuation statements, instruments of further assurance and other instruments,
and will take such other action necessary or advisable to:

                  (i) maintain or preserve the lien and security interest (and

lien and security interest effective.

         (b) Prior to the effectiveness of any amendment to the Sale Agreement,
the Note Issuer shall furnish to the Note Trustee an Opinion of Counsel either

opinion of such counsel, no such action shall be necessary to preserve and

         Section 3.07. Performance of Obligations; Servicing; Commission
Filings.

         (a) The Note Issuer (i) will diligently pursue any and all actions to
enforce its rights under each instrument or agreement included in the Collateral
and (ii) will not take any action and will use its reasonable efforts not to
permit any action to be taken by others that would release any Person from any
of such Person's covenants or obligations under any such instrument or agreement
or that would result in the amendment, hypothecation, subordination, termination
or discharge of, or impair the validity or effectiveness of, any such instrument
or agreement, except, in each case, as expressly permitted in this Note
Indenture, the Sale Agreement, the Servicing Agreement or such other instrument
or agreement.

         (b) The Note Issuer may contract with other Persons to assist it in
performing its duties under this Note Indenture, and any performance of such
duties by a Person identified to the Note Trustee in an Officer's Certificate of
the Note Issuer shall be deemed to be action taken by the Note Issuer.
Initially, the Note Issuer has contracted with the Administrator and the
Servicer to assist the Note Issuer in performing its duties under this Note
Indenture.

         (c) The Note Issuer will punctually perform and observe all of its
obligations and agreements contained in this Note Indenture, the Basic Documents
and in the instruments and agreements included in the Collateral, including
filing or causing to be filed all filings with the DTE pursuant to the Statute,
UCC financing statements and continuation statements required to be filed by it
by the terms of this Note Indenture, the Sale Agreement and the Servicing
Agreement in accordance with and within the time periods provided for herein and
therein. Except as otherwise expressly permitted therein, the Note Issuer shall
not waive, amend, modify, supple-

                                       27
<PAGE>   34
ment or terminate any Basic Document or any provision thereof without the
written consent of the Note Trustee (which consent shall not be withheld if (i)
the Note Trustee shall have received an Officer's Certificate stating that such
waiver, amendment, modification, supplement or termination shall not adversely
affect in any material respect the interests of the Noteholders or the holders
of Certificates and (ii) the Rating Agency Condition shall have been satisfied
with respect thereto) or the Holders of at least a majority of the Outstanding
Amount of Notes.

         (d) If the Note Issuer shall have knowledge of the occurrence of a
Servicer Default under the Servicing Agreement, the Note Issuer shall promptly
give written notice thereof to the Note Trustee, the Certificate Trustee, the
Agencies and the Rating Agencies, and shall specify in such notice the action,
if any, the Note Issuer is taking with respect of such default. If a Servicer
Default shall arise from the failure of the Servicer to perform any of its
duties or obligations under the Servicing Agreement with respect to the
Transition Property, including the RTC Charge, the Note Issuer shall take all
reasonable steps available to it to remedy such failure.

         (e) As promptly as possible after the giving of notice to the Servicer,
the Note Trustee, the Certificate Trustee, the Agencies and the Rating Agencies
of termination of the Servicer's rights and powers pursuant to Section 7.01 of
the Servicing Agreement, the Note Issuer, subject to the approval of the DTE
pursuant to the Financing Order, shall appoint a successor Servicer (the
"Successor Servicer") with the Note Trustee's prior written consent thereto
(which consent shall not be unreasonably withheld), and such Successor Servicer
shall accept its appointment by a written assumption in a form acceptable to the
Note Issuer and the Note Trustee. A Person shall qualify as a Successor Servicer
only if such Person satisfies the requirements of the Servicing Agreement. If
within 30 days after the delivery of the notice referred to above, the Note
Issuer shall not have obtained such a new Servicer, the Note Trustee may
petition the DTE or a court of competent jurisdiction to appoint a Successor
Servicer. In connection with any such appointment, the Note Issuer may make such
arrangements for the compensation of such successor as it and such successor
shall agree, subject to the limitations set forth below and in the Servicing
Agreement, and in accordance and in compliance with Section 7.02 of the
Servicing Agreement, the Note Issuer shall enter into an agreement with such
successor for the servicing of the Transition Property (such agreement to be in
form and substance satisfactory to the Note Trustee).

         (f) Upon any termination of the Servicer's rights and powers pursuant
to the Servicing Agreement, the Note Trustee shall promptly notify the Note
Issuer, the Noteholders, the Certificate Trustee, the Agencies and the Rating
Agencies. As soon as a Successor Servicer is appointed, the Note Issuer shall
notify the Note Trustee, the Noteholders, the Certificate Trustee, the Agencies
and the Rating Agencies of such appointment, specifying in such notice the name
and address of such Successor Servicer.

         (g) Without derogating from the absolute nature of the assignment
granted to the Note Trustee under this Note Indenture or the rights of the Note
Trustee hereunder, the Note Issuer agrees that it will not, without the prior
written consent of the Note Trustee or the Holders of at least a majority in
Outstanding Amount of the Notes, amend, modify, waive, supplement, terminate or
surrender, or agree to any amendment, modification, supplement, termination,

                                       28
<PAGE>   35
waiver or surrender of, the terms of any Collateral or the Basic Documents, or
waive timely performance or observance of any material term by the Seller or the
Servicer under the Sale Agreement or the Servicing Agreement, respectively. If
any such amendment, modification, supplement or waiver shall be so consented to
by the Note Trustee or such Holders, the Note Issuer agrees to execute and
deliver, in its own name and at its own expense, such agreements, instruments,
consents and other documents as shall be necessary or appropriate in the
circumstances. The Note Issuer agrees that no such amendment, modification,
supplement or waiver shall adversely affect the rights of the Holders of the
Notes or Certificates Outstanding at the time of any such amendment,
modification, supplement or waiver, except as otherwise agreed to by the Holders
in accordance with the Basic Documents.

         (h) The Note Issuer shall file with the Commission such periodic
reports, if any, as are required from time to time under Section 13 of the
Exchange Act.

         (i) The Note Issuer shall make all filings required under the Statute
relating to the transfer of the ownership or security interest in the Transition
Property other than those required to be made by the Seller pursuant to the
Basic Documents.

         Section 3.08. Negative Covenants. So long as any Notes are Outstanding,
the Note Issuer shall not:

                  (i) except as expressly permitted by this Note Indenture,
         sell, transfer, exchange or otherwise dispose of any of the properties
         or assets of the Note Issuer, including those included in the
         Collateral, unless directed to do so by the Note Trustee in accordance
         with Article V;

                  (ii) claim any credit on, or make any deduction from the
         principal or interest payable in respect of, the Notes (other than
         amounts properly withheld from such payments under the Code) or assert
         any claim against any present or former Noteholder by reason of the
         payment of the taxes levied or assessed upon any part of the
         Collateral;

                  (iii) terminate its existence or dissolve or liquidate in
         whole or in part; or

                  (iv) (A) permit the validity or effectiveness of this Note
         Indenture to be impaired, or permit the lien of this Note Indenture to
         be amended, subordinated, terminated or discharged, or permit any
         Person to be released from any covenants or obligations with respect to
         the Notes under this Note Indenture except as may be expressly
         permitted hereby, (B) permit any lien, charge, excise, claim, security
         interest, mortgage or other encumbrance (other than the lien of this
         Note Indenture and any statutory lien under Section 1H(e) of the
         Statute) to be created by the Note Issuer on or extend to or otherwise
         arise upon or burden the Collateral or any part thereof or any interest
         therein or the proceeds thereof or (C) subject to any statutory lien
         under Section 1H(e) of the Statute, permit the lien of this Note
         Indenture not to constitute a valid first priority security interest in
         the Collateral.

the Legal Defeasance Option or the Covenant Defeasance Option, the Note Trustee,
on reasonable demand of and at the expense of the Note Issuer, shall execute
proper instruments acknowledging satisfaction and discharge of the obligations
that are terminated pursuant to such exercise.

         (c) Notwithstanding Sections 4.01(a) and 4.01(b) above, (i) rights of
registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments
of principal and interest, (iv) Sections 4.03 and 4.04, (v) the rights,
obligations and immunities of the Note Trustee hereunder (including the rights
of the Note Trustee under Section 6.07 and the obligations of the Note Trustee
under Section 4.03) and (vi) the rights of Noteholders as beneficiaries hereof
with respect to the property deposited with the Note Trustee payable to all or
any of them, shall survive until the Notes, as to which this Note Indenture or
certain obligations hereunder have been satisfied and discharged pursuant to
Section 4.01(a) or 4.01(b), have been paid in full. Thereafter, the obligations
in Sections 6.07 and 4.04 shall survive.

         Section 4.02. Conditions to Defeasance. The Note Issuer may exercise
the Legal Defeasance Option or the Covenant Defeasance Option of Notes only if:

                  (a) the Note Issuer irrevocably deposits or causes to be
         deposited in trust with the Note Trustee cash or U.S. Government
         Obligations for the payment of principal of and interest on each such
         Note to the Scheduled Maturity Date, Optional Redemption Date or
         Mandatory Redemption Date therefor, as applicable;

                  (b) the Note Issuer delivers to the Note Trustee a certificate
         from a nationally recognized firm of Independent accountants expressing
         its opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obligations plus
         any deposited cash without investment will provide cash at such times
         and in such amounts (but, in the case of the Legal Defeasance Option
         only, not more than such amounts) as will be sufficient to pay in
         respect of the Notes (i) subject to clause (ii), principal in
         accordance with the Expected Amortization Schedule therefor, (ii) if to
         be redeemed, the Optional Redemption Price or Mandatory Redemption

         due;

                  (c) in the case of the Legal Defeasance Option, 91 days pass
         after the deposit is made and during the 91-day period no Default
         specified in Section 5.01(v) or (vi) occurs which is continuing at the
         end of the period;

                  (d) no Default has occurred and is continuing on the day of
         such deposit and after giving effect thereto;

                  (e) in the case of an exercise of the Legal Defeasance Option,
         the Note Issuer shall have delivered to the Note Trustee an Opinion of
         Counsel stating that (i) the Note Issuer has received from, or there
         has been published by, the Internal Revenue Service a ruling, or (ii)
         since the date of execution of this Note Indenture, there has been a
         change in the applicable federal income tax law, in either case to the
         effect that, and based thereon such opinion shall confirm that, the
         Holders of the Notes will not recognize income, gain or loss for
         federal income tax purposes as a result of such legal defeasance and
         will be subject to federal income tax on the same amounts, in the same
         manner and at the same times as would have been the case if such legal
         defeasance had not occurred;

                  (f) in the case of an exercise of the Covenant Defeasance
         Option, the Note Issuer shall have delivered to the Note Trustee an
         Opinion of Counsel to the effect that the Holders of the Notes will not
         recognize income, gain or loss for federal income tax purposes as a
         result of such covenant defeasance and will be subject to federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such covenant defeasance had not
         occurred; and

                  (g) the Note Issuer delivers to the Note Trustee an Officer's
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the satisfaction and

                                       35
<PAGE>   42
         discharge of the Notes to the extent contemplated by this Article IV
         have been complied with.

         Before or after a deposit pursuant to this Section 4.02, the Note
Issuer may make arrangements satisfactory to the Note Trustee for the redemption
of such Notes at a future date in accordance with Article X.

         Section 4.03. Application of Trust Money. All moneys or U.S. Government
Obligations deposited with the Note Trustee pursuant to Section 4.01 or 4.02
hereof shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Note Indenture, to the payment, either directly
or through any Paying Agent, as the Note Trustee may determine, to the Holders
of the particular Notes for the payment or redemption of which such moneys have
been deposited with the Note Trustee, of all sums due and to become due thereon
for principal and interest, but such moneys need not be segregated from other
funds except to the extent required herein or in the Servicing Agreement or
required by law.

moneys then held by any Paying Agent other than the Note Trustee under the
provisions of this Note Indenture with respect to such Notes shall, upon demand
of the Note Issuer, be paid to the Note Trustee to be held and applied according
to Section 3.03 and thereupon such Paying Agent shall be released from all
further liability with respect to such moneys.

                                   ARTICLE V

                                    REMEDIES

         Section 5.01. Events of Default. "Event of Default", wherever used

<PAGE>   43
         covenant or agreement, a default in the observance or performance of
         which is elsewhere in this Section specifically dealt with), or any
         representation or warranty of the Note Issuer made in this Note
         Indenture or in any certificate or other writing delivered pursuant
         hereto or in connection herewith proving to have been incorrect in any
         material respect as of the time when the same shall have been made, and
         such default shall continue or not be cured, or the circumstance or
         condition in respect of which such misrepresentation or warranty was
         incorrect shall not have been eliminated or otherwise cured, for a
         period of 30 days after there shall have been given, by registered or
         certified mail, to the Note Issuer by the Note Trustee or to the Note
         Issuer and the Note Trustee by the Holders of at least 25 percent of
         the Outstanding Amount of the Notes, a written notice specifying such
         default or incorrect representation or warranty and requiring it to be
         remedied and stating that such notice is a "Notice of Default"
         hereunder; or

                  (v) the filing of a decree or order for relief by a court
         having jurisdiction in the premises in respect of the Note Issuer or
         any substantial part of the Collateral in an involuntary case under any
         applicable federal or state bankruptcy, insolvency or other similar law
         now or hereafter in effect, or appointing a receiver, liquidator,
         assignee, custodian, trustee, sequestrator or similar official of the
         Note Issuer or for any substantial part of the Collateral, or ordering
         the winding-up or liquidation of the Note Issuer's affairs, and such
         decree or order shall remain unstayed and in effect for a period of 60
         consecutive days; or

                  (vi) the commencement by the Note Issuer of a voluntary case
         under any applicable federal or state bankruptcy, insolvency or other
         similar law now or hereafter in effect, or the consent by the Note
         Issuer to the entry of an order for relief in an involuntary case under
         any such law, or the consent by the Note Issuer to the appointment or
         taking possession by a receiver, liquidator, assignee, custodian,
         trustee, sequestrator or similar official of the Note Issuer or for any
         substantial part of the Collateral, or the making by the Note Issuer of
         any general assignment for the benefit of creditors, or the failure by
         the Note Issuer generally to pay its debts as such debts become due, or
         the taking of action by the Note Issuer in furtherance of any of the
         foregoing.

         The Note Issuer shall deliver to a Responsible Officer of the Note
Trustee, the Certificate Trustee and the Rating Agencies, within five days after
an Authorized Officer has knowledge of the occurrence thereof, written notice in
the form of an Officer's Certificate of any event which with the giving of
notice and the lapse of time would become an Event of Default under clause (iv),
its status and what action the Note Issuer is taking or proposes to take with
respect thereto.

         Section 5.02. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default should occur and be continuing, then and in every such case the
Note Trustee or the Holders of Notes representing not less than a majority of
the Outstanding Amount of the Notes may declare all the Notes to be immediately
due and payable, by a notice in writing to the Note Issuer (and to the Note
Trustee if given by Noteholders), and upon any such declaration the unpaid
principal amount of the Notes, together with accrued and unpaid interest thereon
through the date of acceleration, shall become immediately due and payable.

                                       37
<PAGE>   44
         At any time after such declaration of acceleration of maturity has been
made and before a judgment or decree for payment of the money due has been
obtained by the Note Trustee as hereinafter in this Article V provided, the
Holders of Notes representing a majority of the Outstanding Amount of the Notes,
by written notice to the Note Issuer and the Note Trustee, may rescind and annul
such declaration and its consequences if:

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

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

                           (B) all sums paid or advanced by the Note Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Note Trustee and its agents
                  and counsel and all amounts due under the Fee and Indemnity
                  Agreement; and

                  (ii) all Events of Default, other than the nonpayment of the
         principal of the Notes that has become due solely by such acceleration,
         have been cured or waived as provided in Section 5.12.

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

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

         (a) The Note Issuer covenants that if (i) default is made in the
payment of any interest on any Note when the same becomes due and payable, and
such default continues for a period of five days, (ii) default is made in the
payment of the then unpaid principal of any Note on the Final Maturity Date for
such Note or (iii) default is made in the payment of the Optional Redemption
Price or Mandatory Redemption Price, as applicable, for any Note on the Optional
Redemption Date or Mandatory Redemption Date, as applicable, therefor, the Note
Issuer will, upon demand of the Note Trustee, pay to it, for the benefit of the
Holders of the Notes, the whole amount then due and payable on such Notes for
principal and interest, with interest upon the overdue principal and, to the
extent payment at such rate of interest shall be legally enforceable, upon
overdue installments of interest, at the respective rate borne by the Notes of
the applicable Class 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 Note
Trustee and its agents and counsel and an amount sufficient to cover all amounts
required to be paid by the Note Issuer under the Fee and Indemnity Agreement.

         (b) Subject to Section 11.16, in case the Note Issuer shall fail
forthwith to pay such amounts upon such demand, the Note Trustee, in its own
name and as trustee of an express trust, may institute a Proceeding for the
collection of the sums so due and unpaid, and may prosecute such Proceeding to
judgment or final decree, and may enforce the same against the Note Issuer or

                                       38
<PAGE>   45
other obligor upon such Notes and collect in the manner provided by law out of
the property of the Note Issuer or other obligor upon such Notes, wherever
situated, the moneys adjudged or decreed to be payable.

         (c) If an Event of Default occurs and is continuing, the Note Trustee
may, as more particularly provided in Section 5.04, in its discretion, proceed
to protect and enforce its rights and the rights of the Noteholders, by such
appropriate Proceedings as the Note Trustee shall deem most effective to protect
and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Note Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy or legal or
equitable right vested in the Note Trustee by this Note Indenture or by law.

         (d) In case there shall be pending, relative to the Note Issuer or any
other obligor upon the Notes or any Person having or claiming an ownership
interest in the Collateral, Proceedings under Title 11 of the United States Code
or any other applicable federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Note Issuer or its property or such other obligor or
Person, or in case of any other comparable judicial Proceedings relative to the
Note Issuer or other obligor upon the Notes, or to the creditors or property of
the Note Issuer or such other obligor, the Note Trustee, irrespective of whether
the principal of any Notes shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Note Trustee shall
have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such Proceedings or otherwise:

                  (i) to file and prove a claim or claims for the whole amount
         of principal and interest owing and unpaid in respect of the Notes and
         to file such other papers or documents as may be necessary or advisable
         in order to have the claims of (A) the Note Trustee (including any
         claim for reasonable compensation to the Note Trustee and each
         predecessor Note Trustee, and their respective agents, attorneys and
         counsel, and for reimbursement of all expenses and liabilities
         incurred, and all advances made, by the Note Trustee and each
         predecessor Note Trustee, except as a result of gross negligence or
         willful misconduct), (B) the Noteholders and (C) each Person for whom a
         claim may be made under the Fee and Indemnity Agreement, allowed in
         such Proceedings;

                  (ii) unless prohibited by applicable law and regulations, to
         vote on behalf of the Holders of Notes in any election of a trustee, a
         standby trustee or Person performing similar functions in any such
         Proceedings; and

                  (iii) to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute all amounts
         received with respect to the claims of the Noteholders and of the Note
         Trustee on their behalf;

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such Noteholders to make
payments to the Note Trustee, and, in the event that the Note Trustee shall
consent to the making of payments directly to such Noteholders,

                                       39
<PAGE>   46
to pay to the Note Trustee (or such other beneficiary of the Fee and Indemnity
Agreement) such amounts as shall be sufficient to cover reasonable compensation
and other amounts owing hereunder to the Note Trustee or such Person, each
predecessor Note Trustee and their respective agents, attorneys and counsel, and
all other reasonable expenses and liabilities incurred, and all advances made,
by the Note Trustee and each predecessor Note Trustee except as a result of
gross negligence or willful misconduct.

         (e) Nothing herein contained shall be deemed to authorize the Note
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof or to
authorize the Note Trustee to vote in respect of the claim of any Noteholder in
any such proceeding except, as aforesaid, to vote for the election of a trustee
in bankruptcy or similar Person.

         (f) All rights of action and of asserting claims under this Note
Indenture, or under any of the Notes, may be enforced by the Note Trustee
without the possession of any of the Notes or the production thereof in any
trial or other Proceedings relative thereto, and any such action or proceedings
instituted by the Note Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Note Trustee, each predecessor
Note Trustee and their respective agents and attorneys, shall be for the ratable
benefit of the Holders of the Notes.

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

         Section 5.04. Remedies; Priorities.

         (a) If an Event of Default shall have occurred and be continuing, the
Note Trustee may do one or more of the following (subject to Section 5.05):

                  (i) institute Proceedings in its own name and as trustee of an
         express trust for the collection of all amounts then payable on the
         Notes or under this Note Indenture with respect thereto, whether by
         declaration or otherwise, enforce any judgment obtained, and collect
         from the Note Issuer and any other obligor upon such Notes moneys
         adjudged due;

                  (ii) institute Proceedings from time to time for the complete
         or partial foreclosure of this Note Indenture with respect to the
         Collateral;

                  (iii) exercise any remedies of a secured party under the UCC
         or the Statute and take any other appropriate action to protect and
         enforce the rights and remedies of the Note Trustee and the Holders of
         the Notes; and

                                       40
<PAGE>   47
                  (iv) sell the Collateral or any portion thereof or rights or
         interest therein, at one or more public or private sales called and
         conducted in any manner permitted by law;

provided, however, that the Note Trustee may not sell or otherwise liquidate any
portion of the Collateral following an Event of Default, other than an Event of
Default described in Section 5.01(i), (ii) or (iii), unless (A) the Holders of
100 percent of the Outstanding Amount of the Notes consent thereto, (B) the
proceeds of such sale or liquidation distributable to the Noteholders are
sufficient to discharge in full all amounts then due and unpaid upon such Notes
for principal and interest after taking into account payment of all amounts due
prior thereto pursuant to the priorities set forth in Section 8.02(d) or (C) the
Note Trustee determines that the Collateral will not continue to provide
sufficient funds for all payments on the Notes as they would have become due if
the Notes had not been declared due and payable, and the Note Trustee obtains
the consent of Holders of 66-2/3 percent of the Outstanding Amount of the Notes.
In determining such sufficiency or insufficiency with respect to clause (B) and
(C), the Note Trustee may, but need not, obtain and conclusively rely upon an
opinion of an Independent investment banking or accounting firm of national
reputation as to the feasibility of such proposed action and as to the
sufficiency of the Collateral for such purpose.

         (b) If the Note Trustee collects any money pursuant to this Article V,
it shall pay out such money in accordance with the priorities set forth in
Section 8.02(d).

         Section 5.05. Optional Possession of the Collateral. If the Notes have
been declared to be due and payable under Section 5.02 following an Event of
Default and such declaration and its consequences have not been rescinded and
annulled, the Note Trustee may, but need not, elect to maintain possession of
the Collateral. It is the desire of the parties hereto and the Noteholders that
there be at all times sufficient funds for the payment of principal of and
interest on the Notes, and the Note Trustee shall take such desire into account
when determining whether or not to maintain possession of the Collateral. In
determining whether to maintain possession of the Collateral, the Note Trustee
may, but need not, obtain and conclusively rely upon an opinion of an
Independent investment banking or accounting firm of national reputation as to
the feasibility of such proposed action and as to the sufficiency of the
Collateral for such purpose.

         Section 5.06. Limitation of Suits. No Holder of any Note shall have any
right to institute any Proceeding, judicial or otherwise, with respect to this
Note Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

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

                  (ii) the Holders of not less than 25 percent of the
         Outstanding Amount of the Notes have made written request to the Note
         Trustee to institute such Proceeding in respect of such Event of
         Default in its own name as Note Trustee hereunder;

                  (iii) such Holder or Holders have offered to the Note Trustee
         indemnity satisfactory to it against the costs, expenses and
         liabilities to be incurred in complying with such request;

                                       41
<PAGE>   48
                  (iv) the Note Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity has failed to institute such
         Proceedings; and

                  (v) no direction inconsistent with such written request has
         been given to the Note Trustee during such 60-day period by the Holders
         of a majority of the Outstanding Amount of the Notes;

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 Note 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 Note Indenture, except in
the manner herein provided.

         In the event the Note Trustee shall receive conflicting or inconsistent
requests and indemnity from two or more groups of Holders of Notes, each
representing less than a majority of the Outstanding Amount of the Notes, the
Note Trustee in its sole discretion may determine what action, if any, shall be
taken, notwithstanding any other provisions of this Note Indenture.

         Section 5.07. Unconditional Rights of Noteholders To Receive Principal
and Interest. Notwithstanding any other provisions in this Note Indenture, the
Holder of any Note shall have the right, which is absolute and unconditional,
(a) to receive payment of (i) the interest, if any, on such Note on or after the
due dates thereof expressed in such Note or in this Note Indenture, (ii) the
unpaid principal, if any, of such Notes on or after the Final Maturity Date
therefor or (iii) in the case of redemption, receive payment of the unpaid
principal of and interest, if any, on such Note on or after the Optional
Redemption Date or Mandatory Redemption Date, as applicable, therefor and (b) to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

         Section 5.08. Restoration of Rights and Remedies. If the Note Trustee
or any Noteholder has instituted any Proceeding to enforce any right or remedy
under this Note Indenture and such Proceeding has been discontinued or abandoned
for any reason or has been determined adversely to the Note Trustee or to such
Noteholder, then and in every such case the Note Issuer, the Note Trustee and
the Noteholders shall, subject to any determination in such Proceeding, be
restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Note Trustee and the Noteholders shall
continue as though no such Proceeding had been instituted.

         Section 5.09. Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Note Trustee 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.

                                       42
<PAGE>   49
         Section 5.10. Delay or Omission Not a Waiver. No delay or omission of
the Note Trustee or any Noteholder to exercise any right or remedy accruing upon
any Default or Event of Default shall impair any such right or remedy or
constitute a waiver of any such Default or Event of Default or an acquiescence
therein. Every right and remedy given by this Article V or by law to the Note
Trustee or to the Noteholders may be exercised from time to time, and as often
as may be deemed expedient, by the Note Trustee or by the Noteholders, as the
case may be.

         Section 5.11. Control by Noteholders. The Holders of a majority of the
Outstanding Amount of the Notes (or, if less than all Classes are affected, the
affected Class or Classes) shall have the right to direct the time, method and
place of conducting any Proceeding for any remedy available to the Note Trustee
with respect to the Notes of such Class or Classes or exercising any trust or
power conferred on the Note Trustee with respect to such Class or Classes;
provided, however, that

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

                  (ii) subject to the express terms of Section 5.04, any
         direction to the Note Trustee to sell or liquidate the Collateral shall
         be by the Holders of Notes representing not less than 100 percent of
         the Outstanding Amount of the Notes;

                  (iii) if the conditions set forth in Section 5.05 have been
         satisfied and the Note Trustee elects to retain the Collateral pursuant
         to such Section, then any direction to the Note Trustee by Holders of
         Notes representing less than 100 percent of the Outstanding Amount of
         the Notes to sell or liquidate the Collateral shall be of no force and
         effect; and

                  (iv) the Note Trustee may take any other action deemed proper
         by the Note Trustee that is not inconsistent with such direction;

provided, however, that, subject to Section 6.01, the Note Trustee need not take
any action that it determines might involve it in liability or might materially
adversely affect the rights of any Noteholders not consenting to such action.

         Section 5.12. Waiver of Past Defaults. Prior to the declaration of the
acceleration of the maturity of the Notes as provided in Section 5.02, the
Holders of Notes of not less than a majority of the Outstanding Amount of the
Notes may waive any past Default or Event of Default and its consequences except
a Default (a) in payment of principal of or interest on any of the Notes or (b)
in respect of a covenant or provision hereof which cannot be modified or amended
without the consent of the Holder of each Note or of all Classes affected. In
the case of any such waiver, the Note Issuer, the Note Trustee and the Holders
of the Notes shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other Default
or impair any right consequent thereto.

         Upon any such waiver, such Default shall cease to exist and be deemed
to have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to

                                       43
<PAGE>   50
have been cured and not to have occurred, for every purpose of this Note
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereto.

         Section 5.13. Undertaking for Costs. All parties to this Note Indenture
agree, and each Holder of any Note by such Holder's acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Note Indenture, or in any
suit against the Note Trustee for any action taken, suffered or omitted by it as
Note Trustee, the filing by any party litigant in such suit of an undertaking to
pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to (a) any suit instituted by the Note Trustee, (b) any
suit instituted by any Noteholder, or group of Noteholders, in each case holding
in the aggregate more than 10 percent of the Outstanding Amount of the Notes or
(c) any suit instituted by any Noteholder for the enforcement of the payment of
(i) interest on any Note on or after the due dates expressed in such Note and in
this Note Indenture, (ii) the unpaid principal, if any, of any Note on or after
the Final Maturity Date therefor or (iii) in the case of redemption, the unpaid
principal of and interest on any Note on or after the Optional Redemption Date
or Mandatory Redemption Date, as applicable, therefor.

         Section 5.14. Waiver of Stay or Extension Laws. The Note Issuer
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead or in any manner whatsoever, claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, that may affect the covenants or the performance of
this Note Indenture; and the Note Issuer (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Note Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

         Section 5.15. Action on Notes. The Note Trustee's right to seek and
recover judgment on the Notes or under this Note Indenture shall not be affected
by the seeking, obtaining or application of any other relief under or with
respect to this Note Indenture. Neither the lien of this Note Indenture nor any
rights or remedies of the Note Trustee or the Noteholders shall be impaired by
the recovery of any judgment by the Note Trustee against the Note Issuer or by
the levy of any execution under such judgment upon any portion of the Collateral
or upon any of the assets of the Note Issuer.

         Section 5.16. Performance and Enforcement of Certain Obligations.

         (a) Promptly following a request from the Note Trustee to do so and at
the Note Issuer's expense, the Note Issuer agrees to take all such lawful action
as the Note Trustee may reasonably request to compel or secure the performance
and observance by the Seller and the Servicer, as applicable, of each of their
obligations to the Note Issuer under or in connection with the Sale Agreement
and the Servicing Agreement, respectively, in accordance with the terms thereof,
and

                                       44
<PAGE>   51
to exercise any and all rights, remedies, powers and privileges lawfully
available to the Note Issuer under or in connection with the Sale Agreement and
the Servicing Agreement, respectively, to the extent and in the manner directed
by the Note Trustee, including the transmission of notices of default on the
part of the Seller or the Servicer thereunder and the institution of legal or
administrative actions or proceedings to compel or secure performance by the
Seller or the Servicer of each of their obligations under the Sale Agreement and
the Servicing Agreement, respectively.

         (b) If an Event of Default has occurred, the Note Trustee may, and, at
the direction (which direction shall be in writing or by telephone (confirmed in
writing promptly thereafter)) of the Holders of 66-2/3 percent of the
Outstanding Amount of the Notes shall, subject to Article VI, exercise all
rights, remedies, powers, privileges and claims of the Note Issuer against the
Seller or the Servicer under or in connection with the Sale Agreement and the
Servicing Agreement, respectively, including the right or power to take any
action to compel or secure performance or observance by the Seller or the
Servicer of each of their obligations to the Note Issuer thereunder and to give
any consent, request, notice, direction, approval, extension or waiver under the
Sale Agreement or the Servicing Agreement, respectively, and any right of the
Note Issuer to take such action shall be suspended.

                                   ARTICLE VI

                                THE NOTE TRUSTEE

Section  6.01. Duties of Note Trustee.

         (a) If an Event of Default has occurred and is continuing, the Note
Trustee shall exercise the rights and powers vested in it by this Note Indenture
and use the same degree of care and skill in their exercise as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs.

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

                  (i) the Note Trustee undertakes to perform such duties and
         only such duties as are specifically set forth in this Note Indenture
         and no implied covenants or obligations shall be read into this Note
         Indenture against the Note Trustee; and

                  (ii) in the absence of bad faith on its part, the Note Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Note Trustee and conforming to the
         requirements of this Note Indenture; however, the Note Trustee shall
         examine the certificates and opinions to determine whether or not they
         conform to the requirements of this Note Indenture.

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

                                       45
<PAGE>   52
                  (i) this paragraph does not limit the effect of paragraph (b)
         of this Section;

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

                  (iii) the Note Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 5.11.

         (d) Every provision of this Note Indenture that in any way relates to
the Note Trustee is subject to paragraphs (a) , (b) and (c) of this Section.

         (e) The Note Trustee shall not be liable for interest on any money
received by it except as the Note Trustee may agree in writing with the Note
Issuer.

         (f) Money held in trust by the Note Trustee need not be segregated from
other funds except to the extent required by law or the terms of this Note
Indenture, the Sale Agreement or the Servicing Agreement.

         (g) No provision of this Note Indenture shall require the Note Trustee
to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayments
of such funds or indemnity satisfactory to it against such risk or liability is
not reasonably assured to it.

         (h) Every provision of this Note Indenture relating to the conduct or
affecting the liability of or affording protection to the Note Trustee shall be
subject to the provisions of this Section and to the provisions of the Trust
Indenture Act.

         (i) In the event that the Note Trustee is also acting as Paying Agent
or Note Registrar hereunder, this Article VI shall also be afforded to such
Paying Agent or Note Registrar.

Section  6.02. Rights of Note Trustee.

         (a) The Note Trustee may conclusively rely and shall be fully protected
in relying on any document believed in good faith by it to be genuine and to
have been signed or presented by the proper person. The Note Trustee need not
investigate any fact or matter stated in the document.

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

         (c) The Note Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents or
attorneys or a custodian or nominee, and the Note Trustee shall not be
responsible for any misconduct or negligence on the part of, or

                                       46
<PAGE>   53
for the supervision of, any such agent, attorney, custodian or nominee appointed
with due care by it hereunder.

         (d) The Note Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; provided, however, that the Note Trustee's conduct does not
constitute willful misconduct or gross negligence.

         (e) The Note Trustee may consult with counsel, and the advice or
opinion of counsel with respect to legal matters relating to this Note Indenture
and the Notes shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

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

         (g) The Note Trustee shall not be charged with knowledge of any Default
or Event of Default, unless either (1) a Responsible Officer of the Note Trustee
shall have actual knowledge of the Default or Event of Default, or (2) written
notice of such Default or Event of Default shall have been given to the Note
Trustee by the Note Issuer or by a Holder of the Notes.

Section  6.03. Individual Rights of Note Trustee. The Note Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Note Issuer or its affiliates with the same rights
it would have if it were not Note Trustee. Any Paying Agent, Note Registrar,
co-registrar or co-paying agent may do the same with like rights. However, the
Note Trustee must comply with Sections 6.11 and 6.12.

Section  6.04. Note Trustee's Disclaimer. The Note Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Note Indenture or the Notes, it shall not be accountable for the Note
Issuer's use of the proceeds from the Notes, and it shall not be responsible for
any statement of the Note Issuer in the Note Indenture or in any document issued
in connection with the sale of the Notes or in the Notes other than the Note
Trustee's certificate of authentication.

Section  6.05. Notice of Defaults. If a Default occurs and is continuing and if
it is actually known to a Responsible Officer of the Note Trustee, the Note
Trustee shall mail to the Agencies, each Holder of Notes and to the Rating
Agencies notice of the Default within 30 days after it occurs. Except in the
case of a Default in payment of principal of or interest on any Note, the Note
Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith after consultation with the Certificate Trustee
determines that withholding the notice is in the interests of Noteholders and
the Certificateholders.

                                       47
<PAGE>   54
Section  6.06. Reports by Note Trustee to Holders.

         (a) So long as the Note Trustee is the Note Registrar and Paying Agent,
it shall deliver to each Noteholder such information in its possession as may be
required to enable such Holder to prepare its federal and state income tax
returns.

         (b) On or prior to each Payment Date therefor, the Note Trustee will
deliver to each Holder of Notes on such Payment Date a statement as provided and
prepared by the Servicer which will include (to the extent applicable) the
following information as to the Notes with respect to such Payment Date or the
period since the previous Payment Date, as applicable:

                  (i) the amount of the distribution to Noteholders allocable to
         principal;

                  (ii) the amount of the distribution to Noteholders allocable
         to interest;

                  (iii) the aggregate outstanding Principal Balance of the
         Notes, after giving effect to payments allocated to principal reported
         under (i) above; and

                  (iv) the difference, if any, between the Principal Balance and
         the Projected Principal Balance as of such Payment Date, after giving
         effect to distributions to be made on such Payment Date.

         (c) The Note Issuer shall send a copy of each Certificate of Compliance
delivered to it pursuant to Section 3.03 of the Servicing Agreement and each
Annual Accountant's Report delivered to it pursuant to Section 3.04 of the
Servicing Agreement to the Note Trustee, the Noteholders and the Rating
Agencies.

         If the Note Trustee is also serving as the Certificate Trustee, it
shall also prepare the statements required to be delivered to Certificateholders
pursuant to Section 4.02(d) of the Certificate Indenture.

Section  6.07. Compensation and Indemnity. The Note Issuer shall pay to the Note
Trustee from time to time reasonable compensation for its services. The Note
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Note Issuer shall reimburse the Note Trustee
for all reasonable out-of-pocket expenses, disbursements and advances incurred
or made by it, including costs of collection, in addition to the compensation
for its services. Such expenses shall include the reasonable compensation and
expenses, disbursements and advances of the Note Trustee's agents, counsel,
accountants and experts. The Note Issuer shall indemnify, defend and hold
harmless the Note Trustee and any of its affiliates, officers, directors,
employees and agents (the "Indemnified Persons") from and against any and all
losses, claims, actions, suits, taxes, damages, expenses (including, without
limitation, legal fees and expenses) and liabilities (including liabilities
under state or federal securities laws) of any kind and nature whatsoever
(collectively, "Expenses"), to the extent that such Expenses arise out of or are
imposed upon or asserted against such Indemnified Persons with respect to the
creation, administration, operation or termination of this trust and the
performance by the Note Trustee of its duties hereunder, the failure of the Note
Issuer or any other Person (other than the Person being indemnified) to

                                       48
<PAGE>   55
perform its obligations hereunder or under any of the Basic Documents, or
otherwise in connection with the Basic Documents or the transactions
contemplated thereby, provided, however, that the Note Issuer is not required to
indemnify any Indemnified Person for any Expenses that result from the willful
misconduct or gross negligence of such Indemnified Person. The willful
misconduct or gross negligence of any Note Trustee shall not affect the rights
of any predecessor or successor Note Trustee hereunder. The Note Trustee shall
notify the Note Issuer as soon as is reasonably practicable of any claim for
which it may seek indemnity. Failure by the Note Trustee to so notify the Note
Issuer shall not relieve the Note Issuer of its obligations hereunder. The Note
Issuer shall defend the claim and the Note Trustee may have separate counsel and
the Note Issuer shall pay the fees and expenses of such counsel.

         The Note Issuer's payment obligations to the Note Trustee pursuant to
this Section shall survive the discharge of this Note Indenture or the earlier
resignation or removal of the Note Trustee. When the Note Trustee incurs
expenses after the occurrence of a Default specified in Section 5.01(v) or (vi)
with respect to the Note Issuer, the expenses are intended to constitute
expenses of administration under Title 11 of the United States Code or any other
applicable federal or state bankruptcy, insolvency or similar law.

         The Note Issuer acknowledges and agrees that under the Certificate
Indenture the Certificate Trustee shall pay the fees and expenses of, and shall
indemnify and hold harmless the Note Trustee and the Delaware Trustee, to the
extent that payments required to be made by the Note Issuer to the Note Trustee
under this Section 6.07 or to the Delaware Trustee under the Fee and Indemnity
Agreement, as the case may be, are not made by the Note Issuer when due.

Section  6.08. Replacement of Note Trustee. The Note Trustee may resign at any
time by so notifying the Note Issuer, provided, however, that no such
resignation shall be effective until either (a) the Collateral has been
completely liquidated and the proceeds of the liquidation distributed to the
Noteholders or (b) a successor trustee having the qualifications set forth in
Section 6.11 has been designated and has accepted such trusteeship. The Holders
of a majority in Outstanding Amount of the Notes may remove the Note Trustee by
so notifying the Note Trustee and may appoint a successor Note Trustee. The Note
Issuer shall remove the Note Trustee if:

                  (i) the Note Trustee fails to comply with Section 6.11;

                  (ii) the Note Trustee is adjudged a bankrupt or insolvent;

                  (iii) a receiver or other public officer takes charge of the
         Note Trustee or its property; or

                  (iv) the Note Trustee otherwise becomes incapable of acting.

         If the Note Trustee resigns or is removed or if a vacancy exists in the
office of Note Trustee for any reason (the Note Trustee in such event being
referred to herein as the retiring Note Trustee), the Note Issuer shall promptly
appoint a successor Note Trustee.

                                       49
<PAGE>   56
         A successor Note Trustee shall deliver a written acceptance of its
appointment to the retiring Note Trustee and to the Note Issuer. Thereupon the
resignation or removal of the retiring Note Trustee shall become effective, and
the successor Note Trustee shall have all the rights, powers and duties of the
Note Trustee under this Note Indenture. The successor Note Trustee shall mail a
notice of its succession to Noteholders and to the Rating Agencies. The retiring
Note Trustee shall promptly transfer all property held by it as Note Trustee to
the successor Note Trustee.

         If a successor Note Trustee does not take office within 60 days after
the retiring Note Trustee resigns or is removed, the retiring Note Trustee, the
Note Issuer or the Holders of a majority in Outstanding Amount of the Notes may
petition any court of competent jurisdiction for the appointment of a successor
Note Trustee.

         If the Note Trustee fails to comply with Section 6.11, any Noteholder
may petition any court of competent jurisdiction for the removal of the Note
Trustee and the appointment of a successor Note Trustee.

         Notwithstanding the replacement of the Note Trustee pursuant to this
Section, the Note Issuer's obligations under Section 6.07 shall continue for the
benefit of the retiring Note Trustee.

Section  6.09. Successor Note Trustee by Merger. If the Note Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Note Trustee. The successor Note Trustee
shall mail a notice of its merger, conversion or consolidation to the Rating
Agencies.

         In case at the time such successor or successors by merger, conversion
or consolidation to the Note Trustee shall succeed to the trusts created by this
Note Indenture any of the Notes shall have been authenticated but not delivered,
any such successor to the Note Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Note Trustee may authenticate such Notes
either in the name of any predecessor hereunder or in the name of the successor
to the Note Trustee; and in all such cases such certificates shall be valid for
all purposes hereunder and under the Notes.

Section  6.10. Appointment of Co-Trustee or Separate Trustee.

         (a) Notwithstanding any other provisions of this Note Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the Collateral may at the time be located, the Note Trustee
shall have the power and may execute and deliver all instruments to appoint one
or more Persons to act as a co-trustee or co-trustees, or separate trustee or
separate trustees, of all or any part of the Collateral, and to vest in such
Person or Persons, in such capacity and for the benefit of the Noteholders, such
title to the Collateral, or any part hereof, and, subject to the other
provisions of this Section, such powers, duties, obligations, rights and trusts
as the Note Trustee may consider necessary or desirable. No co-trustee or
separate trustee hereunder shall be required to meet the terms of eligibility as
a

                                       50
<PAGE>   57
successor trustee under Section 6.11 and no notice to Noteholders of the
appointment of any co-trustee or separate trustee shall be required under
Section 6.08 hereof.

         (b) Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                  (i) all rights, powers, duties and obligations conferred or
         imposed upon the Note Trustee shall be conferred or imposed upon and
         exercised or performed by the Note Trustee and such separate trustee or
         co-trustee jointly (it being understood that such separate trustee or
         co-trustee is not authorized to act separately without the Note Trustee
         joining in such act), except to the extent that under any law of any
         jurisdiction in which any particular act or acts are to be performed
         the Note Trustee shall be incompetent or unqualified to perform such
         act or acts, in which event such rights, powers, duties and obligations
         (including the holding of title to the Collateral or any portion
         thereof in any such jurisdiction) shall be exercised and performed
         singly by such separate trustee or co-trustee, but solely at the
         direction of the Note Trustee;

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

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

         (c) Any notice, request or other writing given to the Note Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Note Indenture

Section  8.02. Collection Account.

         (a) Prior to the Issuance Date, the Note Issuer shall open, at the Note
Trustee's Corporate Trust Office, or at another Eligible Institution, one or
more segregated trust accounts in the Note Trustee's name for the deposit of
Estimated RTC Charge Payments and other amounts remitted under the Servicing
Agreement (collectively, the "Collection Account"). The Note Trustee shall hold
the Collection Account for the benefit of Noteholders. The Collection Account
will consist of four subaccounts: a general subaccount (the "General
Subaccount"), a reserve subaccount (the "Reserve Subaccount"), an
overcollateralization subaccount (the "Overcollateralization Subaccount") and a
capital subaccount (the "Capital Subaccount"). All amounts in the Collection
Account not allocated to any other subaccount shall be allocated to the General
Subaccount. Prior to the initial Payment Date, all amounts in the Collection
Account (other than funds deposited into the Capital Subaccount, together with
interest earnings thereon) shall be allocated to the General Subaccount. All
references to the Collection Account shall be deemed to include reference to all
subaccounts contained therein. Withdrawals from and deposits to each of the
foregoing subaccounts of the Collection Account shall be made as set forth in
Section 8.02. The Collection Account shall at all times be maintained in an
Eligible Deposit Account and only the Note Trustee shall have access to the
Collection Account for the purpose of making deposits in and withdrawals from
the Collection Account in accordance with this Note Indenture. Funds in the
Collection Account shall not be commingled with any other moneys. Except as
provided in Section 8.03, all moneys deposited from time to time in the
Collection Account, all deposits therein pursuant to this Note Indenture, and
all investments made in Eligible Investments with such moneys, including all
income or other gain from such investments, shall be held by the Note Trustee in
the Collection Account as part of the Collateral as herein provided.

         (b) The Note Trustee shall have sole dominion and exclusive control
over all moneys in the Collection Account and shall apply such amounts therein
as provided in this Section 8.02. The Note Trustee shall also pay from the
Collection Account any amounts requested to be paid by the Servicer pursuant to
Section 4.03(b) of the Servicing Agreement.

         (c) All Estimated RTC Charge Payments and other remittances under the
Servicing Agreement shall be deposited in the General Subaccount as provided in
Section 4.03 of the Servicing Agreement. All deposits to and withdrawals from
the Collection Account and all allocations to the subaccounts of the Collection
Account shall be made by the Note Trustee in accordance with the written
instructions provided by the Servicer in the Semiannual Servicer Certificate or
as otherwise provided herein.

         (d) On any Business Day upon which the Note Trustee receives a written
request from the Administrator stating that any Operating Expense payable by the
Note Issuer (but only as described in clauses (i) through (iv) below) will
become due and payable prior to the next succeeding Payment Date, and setting
forth the amount and nature of such Operating Expenses, as well any supporting
documentation that the Note Trustee may reasonably request, the Note Trustee,
upon receipt of such information, will make payment of such Operating Expenses
on or before the date such payment is due from amounts on deposit in the General
Subaccount, the

                                       55
<PAGE>   62
Reserve Subaccount, the Overcollateralization Subaccount and the Capital
Subaccount, in that order and only to the extent required to make such payment.

         On each Payment Date, the Note Trustee shall apply, at the direction of
the Servicer, all amounts on deposit in the Collection Account, including all
net earnings thereon (other than on amounts in the Capital Subaccount), to pay
the following amounts, in accordance with the Semiannual Servicer Certificate,
in the following priority:

                  (i) all amounts owed by the Note Issuer to the Note Trustee
         (including indemnity payments and legal fees and expenses) shall be
         paid to the Note Trustee (subject to Section 6.07), all amounts owed by
         the Note Issuer to the Certificate Trustee, the Delaware Trustee , the
         Agencies and the Certificate Issuer under the Fee and Indemnity
         Agreement, as well as an amount sufficient to compensate the
         Certificate Trustee for all amounts payable by the Certificate Trustee
         under Section 6.16 of the Certificate Indenture, as described in the
         last paragraph of Section 6.07, shall be paid to the Certificate
         Trustee, the Delaware Trustee, the Agencies and the Certificate Issuer,
         as appropriate;

                  (ii) the Servicing Fee for such Payment Date and all unpaid
         Servicing Fees from prior Payment Dates shall be paid to the Servicer;

                  (iii) the Administration Fee and all unpaid Administration
         Fees from prior Payment Dates shall be paid to the Administrator;

                  (iv) so long as no Default or Event of Default shall have
         occurred and be continuing or would result from such payment, all other
         Operating Expenses shall be paid to the Persons entitled thereto;
         provided, however, that the amount of such other Operating Expenses
         paid by the Note Trustee from, but not including, the previous Payment
         Date to, and including, the current Payment Date shall not in the
         aggregate exceed $100,000;

                  (v) (A) any overdue Semiannual Interest (together with, to the
         extent lawful, interest on such overdue Semiannual Interest at the
         applicable Note Interest Rate) and (B) Semiannual Interest for such
         Payment Date shall be paid to the Noteholders;

                  (vi) (A) principal due and payable on the Notes as a result of
         an Event of Default or on the Final Maturity Date of the Notes, shall
         be paid to the Noteholders and (B) Semiannual Principal for such
         Payment Date shall be paid to the Noteholders;

                  (vii) unpaid Operating Expenses shall be paid to the Persons
         entitled thereto;

                  (viii) the amount, if any, by which the Required Capital Level
         with respect to all Outstanding Notes exceeds the amount in the Capital
         Subaccount (disregarding any interest earnings held in the Capital
         Subaccount which have not been remitted to the Note Issuer) as of such
         Payment Date shall be allocated to the Capital Subaccount;

                  (ix) the amount, if any, by which the Required
         Overcollateralization Level, with respect to all Outstanding Notes,
         exceeds the amount in the Overcollateralization

                                       56
<PAGE>   63
         Subaccount as of such Payment Date shall be allocated to the
         Overcollateralization Subaccount;

                  (x) the balance, if any, shall be allocated to the Reserve
         Subaccount for distribution on subsequent Payment Dates; and

                  (xi) after principal of and interest on all Notes, and all of
         the other foregoing amounts, have been paid in full, the balance, if
         any, shall be paid to the Note Issuer, free from the lien of this Note
         Indenture.

         (e) All payments of interest and all payments of principal pursuant to
clause (vi)(A) shall be made to such holders pro rata based on the respective
principal amounts of Notes held by such Holders. All payments of principal
pursuant to clause (vi)(B) above shall be made to the Holders of the Class then
entitled to payment, based upon the Expected Amortization Schedule in accordance
with the priority set forth in Section 2.01(c)(iii). Payments in respect of
principal of and interest on any Class of Notes will be made on a pro rata basis
among all the Noteholders of such Class.

         (f) If on any Payment Date, or for any amounts payable under clauses
(i) through (iv) above, on any Business Day, funds on deposit in the General
Subaccount are insufficient to make the payments contemplated by clauses (i)
through (vi) of Section 8.02(d) above, the Note Trustee shall (i) first, draw
from amounts on deposit in the Reserve Subaccount, (ii) second, draw from
amounts on deposit in the Overcollateralization Subaccount and (iii) third, draw
from amounts on deposit in the Capital Subaccount, in each case, up to the
amount of such shortfall in order to make the payments contemplated by clauses
(i) through (vi) of Section 8.02(d). In addition, if on any Payment Date funds
on deposit in the General Subaccount are insufficient to make the allocations
contemplated by clauses (viii) and (ix) above, the Note Trustee shall draw from
amounts on deposit in the Reserve Subaccount to make such allocations. If on any
Payment Date funds on deposit in the Collection Account are insufficient to make
the transfers contemplated by clause (v) above, the Note Trustee will allocate
the funds in the Collection Account among the classes pro rata.

         (g) On any Optional Redemption Date or Mandatory Redemption Date, the
Note Trustee shall pay to the Noteholders the Optional Redemption Price or
Mandatory Redemption Price, as the case may be.

         (h) On the last day of each month, if the amount in the Capital
Subaccount exceeds the Required Capital Level, the Note Trustee shall pay to the
Note Issuer, upon receipt of an Issuer Request, free from the lien of this Note
Indenture, all amounts in the Capital Subaccount in excess of the Required
Capital Level.

Section  8.03. General Provisions Regarding the Collection Account.

         (a) So long as no Default or Event of Default shall have occurred and
be continuing, all or a portion of the funds in the Collection Account shall be
invested in Eligible Investments and reinvested by the Note Trustee upon Issuer
Order; provided, however, that (i) such Eligible

                                       57
<PAGE>   64
Investments shall not mature later than the Business Day prior to the next
Payment Date, (ii) such Eligible Investments shall not be sold, liquidated or
otherwise disposed of at a loss prior to the maturity thereof and (iii) if such
Eligible Investments have a maturity of one month or less, such Eligible
Investments (or the provider thereof) must have a long-term unsecured debt
rating of at least A2 by Moody's (or the equivalent thereof by the other Rating
Agencies) or a short-term rating of at least P-1 by Moody's (or the equivalent
thereof by the other Rating Agencies), and if such Eligible Investments have a
maturity of greater than one month, such Eligible Investments (or the provider
thereof) must have a long-term unsecured debt rating of at least Aaa by Moody's
(or the equivalent thereof by the other Rating Agencies) and a short-term rating
of at least P-1 by Moody's (or the equivalent thereof by the other Rating
Agencies). All income or other gain from investments of moneys deposited in the
Collection Account shall be deposited by the Note Trustee in the Collection
Account, and any loss resulting from such investments shall be charged to the
Collection Account; provided, however, that all income or other gain from
investments of moneys deposited in the Capital Subaccount shall be retained in
the Capital Subaccount, and any loss resulting from such investments shall be
charged to the Capital Subaccount. The Note Issuer will not direct the Note
Trustee to make any investment of any funds or to sell any investment held in
the Collection Account unless the security interest Granted and perfected in
such account will continue to be perfected in such investment or the proceeds of
such sale, in either case without any further action by any Person, and, in
connection with any direction to the Note Trustee to make any such investment or
sale, if requested by the Note Trustee, the Note Issuer shall deliver to the
Note Trustee an Opinion of Counsel, reasonably acceptable to the Note Trustee,
to such effect. In no event shall the Note Trustee be liable for the selection
of Eligible Investments or for investment losses incurred thereon. The Note
Trustee shall have no liability in respect of losses incurred as a result of the
liquidation of any Eligible Investment prior to its stated maturity or the
failure of the Note Issuer to provide timely written investment direction. The
Note Trustee shall have no obligation to invest or reinvest any amounts held
hereunder in the absence of written investment direction pursuant to an Issuer
Order. If the rating of the Eligible Institution, which may be the Note
Trustee's Corporate Trust Office, falls below the rating requirements set forth
in clause (b)(i) of the definition of Eligible Institution, the Delaware
Trustee, on behalf of the Certificate Issuer, shall, within one month after
notice of such rating change, cause the Collection Account to be transferred to
an institution meeting the requirements set forth in clause (b)(i) of the
definition of "Eligible Institution."

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

         (c) If (i) the Note Issuer shall have failed to give written investment
directions for any funds on deposit in the Collection Account to the Note
Trustee by 11:00 a.m. Eastern Time (or such other time as may be agreed by the
Note Issuer and Note Trustee) on any Business Day; or (ii) a Default or Event of
Default shall have occurred and be continuing with respect to the Notes but the
Notes shall not have been declared due and payable pursuant to Section 5.02;
then the Note Trustee shall, to the fullest extent practicable, invest and
reinvest funds in the Collection

                                       58
<PAGE>   65
Account in one or more investments described under paragraph (g) of the
definition of Eligible Investments.

Section  8.04. Release of Collateral.

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

         (b) The Note Trustee shall, at such time as there are no Notes
Outstanding, release any remaining portion of the Collateral that secured the
Notes from the lien of this Note Indenture and release to the Note Issuer or any
other Person entitled thereto any funds then on deposit in the Collection
Account. The Note Trustee shall release property from the lien of this Note
Indenture pursuant to this Section 8.04(b) only upon receipt of an Issuer
Request accompanied by an Officer's Certificate, an Opinion of Counsel and (if
required by the Trust Indenture Act) Independent Certificates in accordance with
Trust Indenture Act Sections 314(c) and 314(d)(1) meeting the applicable
requirements of Section 11.01.

Section  8.05. Opinion of Counsel. The Note Trustee shall receive at least seven
days' notice when requested by the Note Issuer to take any action pursuant to
Section 8.04(a), accompanied by copies of any instruments involved, and the Note
Trustee shall also require, as a condition to such action, an Opinion of
Counsel, in form and substance reasonably satisfactory to the Note Trustee,
stating the legal effect of any such action, outlining the steps required to
complete the same, and concluding that all conditions precedent to the taking of
such action have been complied with and such action will not materially and
adversely impair the security for the Notes or the rights of the Noteholders in
contravention of the provisions of this Note Indenture; provided, however, that
such Opinion of Counsel shall not be required to express an opinion as to the
fair value of the Collateral. Counsel rendering any such opinion may rely,
without independent investigation, on the accuracy and validity of any
certificate or other instrument delivered to the Note Trustee in connection with
any such action.

Section  8.06. Reports by Independent Accountants. As of the Issuance Date, the
Note Issuer shall appoint a firm of Independent certified public accountants of
recognized national reputation for purposes of preparing and delivering the
reports or certificates of such accountants required by this Note Indenture. In
the event such firm requires the Note Trustee to agree to the procedures
performed by such firm, the Note Issuer shall direct the Note Trustee in writing
to so agree; it being understood and agreed that the Note Trustee will deliver
such letter of agreement in conclusive reliance upon the direction of the Note
Issuer, and the Note Trustee makes no independent inquiry or investigation to,
and shall have no obligation or liability in respect of, the sufficiency,
validity or correctness of such procedures. Upon any resignation by such firm
the Note Issuer shall provide written notice thereof to the Note Trustee and
shall promptly appoint a

                                       59
<PAGE>   66
successor thereto that shall also be a firm of Independent certified public
accountants of recognized national reputation. If the Note Issuer shall fail to
appoint a successor to a firm of Independent certified public accountants that
has resigned within 15 days after such resignation, the Note Trustee shall
promptly notify the Note Issuer of such failure in writing. If the Note Issuer
shall not have appointed a successor within 10 days thereafter the Note Trustee
shall promptly appoint a successor firm of Independent certified public
accountants of recognized national reputation; provided, however, that the Note
Trustee shall have no liability with respect to such appointment if the Note
Trustee acted with due care with respect thereto. The fees of such Independent
certified public accountants and its successor shall be payable by the Note
Issuer.

respective rights, limitations of rights, obligations, duties, liabilities and
immunities under this Note Indenture of the Note Trustee, the Note Issuer and
the Holders of the Notes shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments, and all
the terms and conditions of any such supplemental note indenture shall be and be
deemed to be part of the terms and conditions of this Note Indenture for any and
all purposes. If required by the Note Trustee, Notes may bear a notation in form
approved by the Note Trustee as to any matter provided for in such supplemental
note indenture. If the Note Issuer or the Note Trustee shall so determine, new

Issuer, to any such supplemental note indenture may be prepared and executed by
the Note Issuer and authenticated and delivered by the Note Trustee in exchange
for Outstanding Notes.

Section  9.05. Conformity with Trust Indenture Act. Every amendment of this Note
Indenture and every supplemental note indenture executed pursuant to this

Section  11.02. Form of Documents Delivered to Note Trustee. In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, only one such Person, or that they be so certified
or covered by only one document, but one such Person may certify or give an
opinion with respect to some matters and one or more other such Persons as to
other matters, and any such Person may certify or give an opinion as to such
matters in one or several documents.

         Any certificate or opinion of an Authorized Officer of the Note Issuer
may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his or her certificate or
opinion is based are erroneous. Any such certificate of an Authorized Officer or
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Servicer, the Seller, the Note Issuer or the Administrator, stating that the
information with respect to such factual matters is in the possession of the
Servicer, the Seller, the Note Issuer or the Administrator, unless such counsel
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to such matters are erroneous.

         Whenever in this Note Indenture, in connection with any application or
certificate or report to the Note Trustee, it is provided that the Note Issuer
shall deliver any document as a

                                       67
<PAGE>   74
condition of the granting of such application, or as evidence of the Note
Issuer's compliance with any term hereof, it is intended that the truth and
accuracy, at the time of the granting of such application or at the effective
date of such certificate or report (as the case may be), of the facts and
opinions stated in such document shall in such case be conditions precedent to
the right of the Note Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Note Trustee's right to rely upon the truth and accuracy
of any statement or opinion contained in any such document as provided in
Article VI.

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

waiver or other action provided by this Note 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 agents
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 Note Trustee, and, where it is hereby expressly required, to
the Note 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 Note Indenture and (subject to Section 6.01) conclusive
in favor of the Note Trustee and the Note Issuer, if made in the manner provided
in this Section.

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

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

Section  11.05. Notices to Noteholders; Waiver. Where this Note 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 such Noteholder's address as it appears on the Note Register, not
later

                                       70
<PAGE>   77
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. In any case where 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 that is mailed in the manner herein
provided shall conclusively be presumed to have been duly given.

         Where this Note 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 Note
Trustee but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such a 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 of Noteholders when such notice is required to be
given pursuant to any provision of this Note Indenture, then any manner of
giving such notice as shall be satisfactory to the Note Trustee shall be deemed
to be a sufficient giving of such notice.

         Where this Note Indenture provides for notice to the Rating Agencies,
failure to give such notice shall not affect any other rights or obligations
created hereunder, and shall not under any circumstance constitute a Default or
Event of Default.

Section  11.06. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof that is required to
be included in this Note Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control.

         The provisions of Trust Indenture Act Sections 310 through 317 that
impose duties on any person (including the provisions automatically deemed
included herein unless expressly excluded by this Note Indenture) are a part of
and govern this Note Indenture, whether or not physically contained herein.

Section  11.07. Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

Section  11.08. Successors and Assigns. All covenants and agreements in this
Note Indenture and the Notes by the Note Issuer shall bind its successors and
assigns, whether so expressed or not.

         All agreements of the Note Trustee in this Note Indenture shall bind
its successors.

Section  11.09. Severability. In case any provision in this Note 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  11.10. Benefits of Note Indenture. Nothing in this Note Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Noteholders, and any other party
secured hereunder, and any other Person with an

                                       71
<PAGE>   78
ownership interest in any part of the Collateral, any benefit or any legal or
equitable right, remedy or claim under this Note Indenture.

Section  11.11. Legal Holidays. In any case where the date on which any payment
is due shall not be a Business Day, then (notwithstanding any other provision of
the Notes or this Note Indenture) payment need not be made on such date, but may
be made on the next succeeding Business Day with the same force and effect as if
made on the date on which nominally due, and no interest shall accrue for the
period from and after any such nominal date.

Section  11.12. GOVERNING LAW. THIS NOTE INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS, WITHOUT REFERENCE
TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF
THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS. THE
PERFECTION OF ANY INTERESTS IN THE SECURITIES ACCOUNT AND THE SECURITIES
ENTITLEMENTS SHALL BE DETERMINED BY THE LAWS OF THE COMMONWEALTH OF
MASSACHUSETTS.

Section  11.13. Counterparts. This Note 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.

Section  11.14. Recording of Note Indenture. If this Note Indenture is subject
to recording in any appropriate public recording offices, such recording is to
be effected by the Note Issuer and at its expense accompanied by an Opinion of
Counsel (which may be counsel to the Note Trustee or any other counsel
reasonably acceptable to the Note Trustee) to the effect that such recording is
necessary either for the protection of the Noteholders or any other Person
secured hereunder or for the enforcement of any right or remedy granted to the
Note Trustee under this Note Indenture.

Section  11.15. Trust Obligation. No recourse may be taken, directly or
indirectly, with respect to the obligations of the Note Issuer or the Note
Trustee on the Notes or under this Note Indenture or any certificate or other
writing delivered in connection herewith or therewith, against (i) the Note
Trustee in its individual capacity, (ii) any owner of a beneficial interest in
the Note Issuer or (iii) any partner, owner, beneficiary, agent, officer,
director or employee of the Note Trustee in its individual capacity, any holder
of a beneficial interest in the Note Issuer or the Note Trustee or of any
successor or assign of the Note Trustee in its individual capacity, except as
any such Person may have expressly agreed (it being understood that the Note
Trustee has no such obligations in its individual capacity).

Section  11.16. No Recourse to Note Issuer. Notwithstanding any provision of
this Note Indenture or any Supplemental Note Indenture to the contrary,
Noteholders shall have no recourse against the Note Issuer, but shall look only
to the Collateral, with respect to any amounts due to the Noteholders hereunder.

Section  11.17. Inspection. The Note Issuer agrees that, on reasonable prior
notice, it will permit any representative of the Note Trustee, during the Note
Issuer's normal business hours, to

                                       72
<PAGE>   79
examine all the books of account, records, reports, and other papers of the Note
Issuer, to make copies and extracts therefrom, to cause such books to be audited
by Independent certified public accountants, and to discuss the Note Issuer's
affairs, finances and accounts with the Note Trustee's officers, employees, and
Independent certified public accountants, all at such reasonable times and as
often as may be reasonably requested. The Note Trustee shall and shall cause its
representatives to hold in confidence all such information except to the extent
disclosure may be required by law (and all reasonable applications for
confidential treatment are unavailing) and except to the extent that the Note
Trustee may reasonably determine that such disclosure is consistent with its
obligations hereunder. Notwithstanding anything herein to the contrary, the
foregoing shall not be construed to prohibit (i) disclosure of any and all
information that is or becomes publicly known, or information obtained by the
Note Trustee from sources other than the Note Issuer, provided such parties are
rightfully in possession of such information and do not have an obligation of
confidentiality, (ii) disclosure of any and all information (A) if required to
do so by any applicable statute, law, rule or regulation, (B) pursuant to any
subpoena, civil investigative demand or similar demand or request of any court
or regulatory authority exercising its proper jurisdiction, (C) in any
preliminary or final offering circular, registration statement or contract or
other document pertaining to the transactions contemplated by this Note
Indenture or the Basic Documents approved in advance by the Note Issuer or (D)
to any affiliate, independent or internal auditor, agent, employee or attorney
of the Note Trustee having a need to know the same, provided that such parties
agree to be bound by the confidentiality provisions contained in this Section
11.17, or (iii) any other disclosure authorized by the Note Issuer.

         IN WITNESS WHEREOF, the Note Issuer and the Note Trustee have caused

duly authorized and duly attested, all as of the day and year first above
written.

                                [REVERSE OF NOTE]


         This Class A-[ ] Note is one of a duly authorized issue of Notes of the
Note Issuer, designated as its BEC Funding LLC Notes (herein called the
"Notes"), issuable in one or more Classes, and further designated as a Class A-[
] Note (collectively with all other Class A-[ ] Notes of this issue, the "Class
A-[ ] Notes"), all issued under a Note Indenture dated as of [ ], 1999 (the
"Note Indenture"), between the Note Issuer and The Bank of New York, as Note
Trustee (the "Note Trustee," which term includes any successor trustee under the
Note Indenture), to which Note Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights and
obligations thereunder of the Note Issuer, the Note Trustee and the Holders of
the Notes. All terms used in this Class A-[ ] Note that are defined in the Note
Indenture, as supplemented or amended, shall have the meanings assigned to them
in the Note Indenture, as supplemented or amended.

         The Class A-[ ] Notes and the other Classes of Notes issued by the Note
Issuer are and will be equally and ratably secured by the collateral pledged as
security therefor, as provided in the Note Indenture.

         The principal of this Class A-[ ] Note shall be payable on each Payment
Date only to the extent that amounts in the Collection Account are available
therefor, and only until the outstanding principal balance thereof on such
Payment Date (after giving effect to all payments of principal, if any, made on
such Payment Date) has been reduced to the principal balance specified in the
Expected Amortization Schedule which is attached to the Note Indenture as
Schedule A, unless payable earlier either because (x) an Event of Default shall
have occurred and be continuing and the Note Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes
have declared the Notes to be immediately due and payable in accordance with
Section 5.02 of the Note Indenture, (y) the Note Issuer, at its option, shall
have called for the redemption of the Notes pursuant to Section 10.01 of the
Note Indenture or (z) the Note Issuer shall have called for the redemption of
the Notes pursuant to Section 10.04 of the Note Indenture if the Seller is
required to repurchase the Transition Property pursuant to Section 5.01(b) of
the Sale Agreement. However, actual principal payments may be made in lesser
than expected amounts and at later than expected times as determined pursuant to
Section 8.02 of the Note Indenture. The entire unpaid principal amount of this
Class A-[ ] Note shall be due and payable on the earlier of the Final Maturity
Date hereof, the optional Redemption Date, if any, and the Mandatory Redemption
Date, if any, herefor. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not then previously
paid, on the date on which an Event of Default shall have occurred and be
continuing and the Note Trustee or the Holders of the Notes representing not
less than a majority of the Outstanding Amount of the Notes have declared the
Notes to be immediately due and payable in the manner provided in Section 5.02
of the Note Indenture. All principal payments on the Class A-[ ] Notes shall be
made pro rata to the Class A-[ ] Noteholders entitled thereto based on the
respective principal amounts of the Class A-[ ] Notes held by them.

                                      B-4
<PAGE>   89
         Payments of interest on this Class A-[ ] Note due and payable on each
Payment Date, together with the installment of principal shall be made by check
mailed first-class, postage prepaid, to the Person whose name appears as the
Registered Holder of this Class A-[ ] Note (or one or more Predecessor Notes) on
the Note Register as of the close of business on the Record Date, except that
with respect to Notes registered on the Record Date in the name of the
Certificate Trustee, payments will be made by wire transfer in immediately
available funds to the account designated by the Certificate Trustee and except
for the final installment of principal payable with respect to this Class A-[ ]
Note on a Payment Date which shall be payable as provided below. Such checks
shall be mailed to the Person entitled thereto at the address of such Person as
it appears on the Note Register as of the applicable Record Date without
requiring that this Class A-[ ] Note be submitted for notation of payment. Any
reduction in the principal amount of this Class A-[ ] Note (or any one or more
Predecessor Notes) effected by any payments made on any Payment Date shall be
binding upon all future Holders of this Class A-[ ] Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not noted hereon. If funds are expected to be available, as
provided in the Note Indenture, for payment in full of the then remaining unpaid
principal amount of this Class A-[ ] Note on a Payment Date, then the Note
Trustee, in the name of and on behalf of the Note Issuer, will notify the Person
who was the Registered Holder hereof as of the Record Date preceding such
Payment Date by notice mailed no later than five days prior to such final
Payment Date and shall specify that such final installment will be payable only
upon presentation and surrender of this Class A-[ ] Note and shall specify the
place where this Class A-[ ] Note may be presented and surrendered for payment
of such installment.

         The Note Issuer shall pay interest on overdue installments of interest
at the Note Interest Rate to the extent lawful.

         As provided in the Note Indenture, the Class A-[ ] Notes may be
redeemed, in whole but not in part, at the option of the Note Issuer on any
Payment Date at the Optional Redemption Price if, after giving effect to
payments that would otherwise be made on such Payment Date, the Outstanding
Amount of the Notes has been reduced to less than five percent of the initial
principal balance thereof. In addition, as provided in the Note Indenture, if
the Seller is required to repurchase the Transition Property pursuant to Section
5.01(b) of the Sale Agreement, the Note Issuer will be required to redeem all
outstanding Notes, including the Class A-[ ] Notes, on or before the fifth
Business Day following the Repurchase Date (as defined in the Sale Agreement).

         As provided in the Note Indenture and subject to certain limitations
set forth therein, the transfer of this Class A-[ ] Note may be registered on
the Note Register upon surrender of this Class A-[ ] Note for registration of
transfer at the office or agency designated by the Note Issuer pursuant to the
Note Indenture, duly endorsed by, or accompanied by (a) a written instrument of
transfer in form satisfactory to the Note Trustee duly executed by the Holder
hereof or his attorney duly authorized in writing, with such signature
guaranteed by an institution which is a member of one of the following
recognized Signature Guaranty Programs: (i) The Securities

                                      B-5
<PAGE>   90
Transfer Agent Medallion Program (STAMP); (ii) The New York Stock Exchange
Medallion Program (MSP); (iii) The Stock Exchange Medallion Program (SEMP); or
(iv) in such other guarantee program acceptable to the Note Trustee, and (b)
such other documents as the Note Trustee may require, and thereupon one or more
new Class A-[ ] Notes of Minimum Denominations and in the same aggregate
principal amount will be issued to the designated transferee or transferees. No
service charge will be charged for any registration of transfer or exchange of
this Class A-[ ] Note, but the transferor may be required to pay a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any such registration of transfer or exchange, other than
exchanges pursuant to Section 2.04 of the Note Indenture not involving any
transfer.

         Each Noteholder, by acceptance of a Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Note Issuer or the Note Trustee on the Notes or under the Note Indenture
or any certificate or other writing delivered in connection therewith, against
(i) the Note Trustee in its individual capacity, (ii) any owner of a beneficial
interest in the Note Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director or employee of the Note Trustee in its individual capacity,
any holder of a beneficial interest in the Note Issuer or the Note Trustee or of
any successor or assign of the Note Trustee in its individual capacity, except
as any such Person may have expressly agreed (it being understood that the Note
Trustee has no such obligations in its individual capacity).

         Prior to the due presentment for registration of transfer of this Class
A-[ ] Note, the Note Issuer, the Note Trustee and any agent of the Note Issuer
or the Note Trustee may treat the Person in whose name this Class A-[ ] Note is
registered (as of the day of determination) as the owner hereof for the purpose
of receiving payments of principal of and interest on this Class A-[ ] Note and
for all other purposes whatsoever, whether or not this Class A-[ ] Note be
overdue, and neither the Note Issuer, the Note Trustee nor any such agent shall
be affected by notice to the contrary.

         The Note Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Note Issuer and the rights of the Holders of the Notes under
the Note Indenture at any time by the Note Issuer with the consent of the
Holders of Notes representing a majority of the Outstanding Amount of all Notes
at the time Outstanding of each Class to be affected. The Note Indenture also
contains provisions permitting the Holders of Notes representing specified
percentages of the Outstanding Amount of the Notes, on behalf of the Holders of
all the Notes, to waive compliance by the Note Issuer with certain provisions of
the Note Indenture and certain past defaults under the Note Indenture and their
consequences. Any such consent or waiver by the Holder of this Class A-[ ] Note
(or any one of more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Class A-[ ] Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu
hereof whether or not notation of such consent or waiver is made upon this Class
A-[ ] Note. The Note Indenture also permits the Note Trustee to amend or waive

                                      B-6
<PAGE>   91
certain terms and conditions set forth in the Note Indenture without the consent
of Holders of the Notes issued thereunder.

         The term "Note Issuer" as used in this Class A-[ ] Note includes any
successor to the Note Issuer under the Note Indenture.

         The Note Issuer is permitted by the Note Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Note
Trustee and the Holders of Notes under the Note Indenture.

         The Class A-[ ] Notes are issuable only in registered form in
denominations as provided in the Note Indenture, subject to certain limitations
therein set forth.

         This Class A-[ ] Note and the Note Indenture shall be construed in
accordance with the laws of The Commonwealth of Massachusetts, without reference
to its conflict of law provisions, and the obligations, rights and remedies of
the parties hereunder and thereunder shall be determined in accordance with such
laws.

         No reference herein to the Note Indenture and no provision of this
Class A-[ ] Note or of the Note Indenture shall alter or impair the obligation
of the Note Issuer, which is absolute and unconditional, to pay the principal of
and interest on this Class A-[ ] Note at the times, place, and rate, and in the
coin or currency herein prescribed.

         The Holder of this Class A-[ ] Note by the acceptance hereof agrees
that, notwithstanding any provision of the Note Indenture to the contrary, the
Holder shall have no recourse against the Note Issuer, but shall look only to
the Collateral, with respect to any amounts due to the Holder under this Class
A-[ ] Note.

precedent, if any, provided for in this Certificate Indenture relating to the
proposed action have been complied with and, if requested by the Certificate

         the definitions herein relating thereto;

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

                  (c) a statement that, in the opinion of each such signatory,
         such signatory has made such examination or investigation as is
         necessary to enable such signatory 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

         Section 1.03. Form of Documents Delivered to Certificate Trustee. In
any case where several matters are required to be certified by, or covered by an
opinion of, any specified Person, it is not necessary that all such matters be
certified by, or covered by the opinion of, only one such Person, or that they
be so certified or covered by only one document, but one such Person may certify
or give an opinion with respect to some matters and one or more other such
Persons as to other matters, and any such Person may certify or give an opinion
as to such matters in one or several documents.

         Any certificate or opinion of an Authorized Representative of the
Certificate Issuer may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless such officer
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate of an
Authorized Representative or Opinion of Counsel may be based, insofar as it
relates to factual matters, upon a certificate or opinion of, or representations
by, an officer or officers of the Servicer, the Seller, the Note Issuer or the
Administrator, stating that the information with respect to such factual matters
is in the possession of the Servicer, the Seller, the Note Issuer or the
Administrator, as the case may be, unless such officer or counsel knows, or in
the exercise of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

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


                                       12

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

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

         (c) The ownership of Certificates shall be proved by the Certificate
Register.

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

         (e) The Certificate Issuer may at its option by delivery of an
Officer's Certificate to the Certificate Trustee set a record date to determine
the Holders of any Class of Certificates entitled to give any consent, request,
demand, authorization, direction, notice, waiver or other Act. Notwithstanding
316(c) of the Trust Indenture Act, such record date shall be the record date
specified in such Officer's Certificate, which shall be the date not more than
30 days prior to the first solicitation of Certificateholders in connection
therewith. If such a record date is fixed, such consent, request, demand,
authorization, direction, notice, waiver or other Act may be given before or
after such record date, but only the Holders of Certificates of the applicable
Class at the close of business on such record date shall be deemed to be
Certificateholders of such Class for the purposes of determining whether Holders
of the requisite aggregate Outstanding Amount of Certificates of such Class have
authorized or agreed or consented to such consent, request, demand,
authorization, direction, notice, waiver or other Act, and for that purpose the
aggregate Outstanding Amount of Certificates of such Class shall be computed as
of such record date; provided, however, that no such consent, request, demand,
authorization, direction, notice, waiver or other Act by the Holders of
Certificates of such Class on such record date shall be


                                       13
<PAGE>   18
deemed effective unless it shall become effective pursuant to the provisions of
this Certificate Indenture not later than one year after the record date.

         (f) Except as otherwise provided in the definition of Outstanding,
Certificates of any Class owned by or pledged to any Person shall have an equal
and proportional benefit under the provisions of this Certificate Indenture,
without preference, priority or distinction as among all of the Certificates of
that Class.

Notes, as specified in Section 1(b) of the Note Purchase Agreement; and

         (f) The Rating Agency Condition shall have been satisfied with respect

         Section 2.03. Form, Denomination and Execution of Certificates. The
Certificates shall be issued in registered form without coupons and shall be
substantially in the form attached hereto as Exhibit A, with the following
filled in: (a) the designation of the Classes thereof, which shall be the same
designation as the related Class or Classes of Notes, (b) the Certificate number
or numbers thereof, (c) the date of authentication thereof, which shall be the
same as the Issuance Date of the related Class or Classes of Notes, and (d) the
Original Principal Amount thereof, which shall equal, in the aggregate, the
principal amount of the Notes; and with such omissions, variations and
insertions as are permitted by this Certificate Indenture, and may have such
letters, numbers or other marks of identification and such legends or
endorsements printed, lithographed or engraved thereon as may be required to
comply with the rules of any securities exchange on which any Class or Classes
of the Certificates may be listed or to conform to any usage in respect thereof,
or as may, consistently herewith, be prescribed by the Certificate Trustee or by
the Certificate Issuer (with the prior written approval of the Note Issuer), and
as evidenced by the execution and authentication of such Certificates.

         Except as provided in Section 2.12, the definitive Certificates of each
Class shall be printed, lithographed or engraved or produced by any combination
of these methods or may be produced in any other manner permitted by the rules
of any securities exchange on which the Certificates of such Class may be
listed, as evidenced by an order by an Authorized Representative of the
Certificate Issuer, relating to the authentication of such Certificates by the
Certificate Trustee.

         The Certificates of each Class shall be issued in not less than Minimum

         The Certificates shall be executed on behalf of the Certificate Issuer
by the Delaware Trustee by manual or facsimile signature of a Responsible

authorized to sign on behalf of the Certificate Issuer shall be validly issued
by the Certificate Issuer, notwithstanding that such individual has ceased to be
so authorized prior to the authentication and delivery of such Certificates or
did not hold such office at the date of such Certificates. No Certificate shall
be entitled to any benefit under this Certificate Indenture, or be valid for any
purpose, unless there appears on such Certificate a certificate of
authentication substantially in the form set forth in Exhibit A hereto, executed
by the Certificate Trustee (or any Authentication Agent) by manual signature,
and such certificate of authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication.


                                       17

         Section 2.04. Authentication of Certificates. The Certificate Trustee
shall duly authenticate and deliver Certificates of each Class in authorized
denominations equaling, in the aggregate for each Class of Certificates, the
aggregate initial principal amount of the Notes of such Class.

         Section 2.05. Temporary Certificates. Pending the preparation of
definitive Certificates of any Class, the Delaware Trustee on behalf of the
Certificate Issuer may execute, and the Certificate Trustee or any
Authentication Agent upon written order of the Certificate Issuer shall
authenticate and deliver, temporary Certificates of such Class that are printed,
lithographed, typewritten or otherwise produced, in any denomination, containing
substantially the same terms and provisions as set forth in Exhibit A, except
for such appropriate insertions, omissions, substitutions and other variations
relating to their temporary nature as the Certificate Issuer may determine, as
evidenced by the execution of such temporary Certificates by the Delaware
Trustee on behalf of the Certificate Issuer.

         If temporary Certificates of any Class are issued, the Certificate
Issuer will cause definitive Certificates of such Class to be prepared without
unreasonable delay. After the preparation of definitive Certificates of such
Class, the temporary Certificates shall be exchangeable for definitive
Certificates of such Class upon surrender of the temporary Certificates at the
Corporate Trust Office of the Certificate Trustee, or at the office or agency of
the Certificate Trustee maintained in accordance with Section 6.11, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Certificates, the Delaware Trustee on behalf of the Certificate Issuer
shall execute and the Certificate Trustee shall authenticate and deliver in
exchange therefor definitive Certificates (of the same Class as the temporary
Certificates surrendered) of authorized denominations of a like aggregate
Original Principal Amount. Until so exchanged, such temporary Certificates shall
in all respects be entitled to the same benefits under this Certificate
Indenture as definitive Certificates of the same Class.

         Section 2.06. Registration of Transfer and Exchange of Certificates.
The Certificate Trustee shall cause to be kept at the office of agency to be
maintained by it in accordance with the provisions of Section 6.11 a register
(the "Certificate Register") in which, subject to such reasonable regulations as
it may prescribe, the Certificate Trustee shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.
The Certificate Trustee shall initially be the registrar (the "Certificate
Registrar") for the purpose of registering Certificates and transfers and
exchanges of Certificates as herein provided.

         Subject to this Section 2.06, upon surrender for registration of
transfer of any Certificate at the Corporate Trust Office or such other office
or agency maintained by the Certificate Trustee in accordance with Section 6.11,
the Delaware Trustee on behalf of the Certificate Issuer shall execute, and the
Certificate Trustee shall authenticate and deliver, in the name of the
designated transferee, one or more new Certificates (of the same Class as the
Certificates surrendered for registration of transfer) in authorized
denominations of a like aggregate Original Principal Amount; provided, however,
that if any such surrendered Certificate shall have become or within 15 days
shall be due and payable or shall have been called for redemption, instead of
issuing a replacement Certificate, the Certificate Trustee may pay such
surrendered Certificate when so due and payable or upon the Special Distribution
Date without surrender thereof.


                                       18
<PAGE>   23
         At the option of a Certificateholder, Certificates may be exchanged for
other Certificates (of the same Class as the Certificates surrendered for
registration of exchange) of authorized denominations of a like aggregate
Original Principal Amount, upon surrender of the Certificates to be exchanged at
any such office or agency. Whenever any Certificates are so surrendered for
exchange, the Delaware Trustee on behalf of the Certificate Issuer shall
execute, and the Certificate Trustee shall authenticate and deliver the
Certificates that the Certificateholder making the exchange is entitled to
receive.

         Every Certificate presented or surrendered for registration of transfer
or exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Certificate Trustee and the Certificate
Registrar duly executed by the Certificateholder thereof or its attorney duly
authorized in writing.

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

         All Certificates surrendered for registration of transfer or exchange
shall be cancelled and subsequently destroyed by the Certificate Trustee in
accordance with its customary practices.

         Section 2.07. Certificateholders' Lists and Reports by Certificate
Trustee.

         (a) The Certificate Issuer To Furnish Certificate Trustee with Names
and Addresses of Certificateholders. The Certificate Registrar on behalf of the
Certificate Issuer will furnish or cause to be furnished to the Certificate
Trustee within 15 days after each Record Date, and at such other times as the
Certificate Trustee may request in writing, within 30 days after receipt by the
Certificate Issuer of any such request, a list, in such form as the Certificate
Trustee may reasonably require, of all information in the possession or control
of the Certificate Issuer as to the names and addresses of the
Certificateholders, in each case as of a date not more than 15 days prior to the
time such list is furnished; provided, however, that so long as the Certificate
Trustee is the sole Certificate Registrar, no such list need be furnished; and
provided further, however, that no such list need be furnished for so long as a
copy of the Certificate Register is being furnished to the Certificate Trustee
pursuant to Section 6.11.

         Upon the written request of any Certificateholder or Certificateholders
of record holding Certificates evidencing not less than ten percent of the
aggregate Outstanding Amount of Certificates, the Certificate Trustee shall
afford such Certificateholder or Certificateholders access during business hours
to the current list of Certificateholders for purposes of communicating with
other Certificateholders with respect to their rights under this Certificate
Indenture.

         (b) Preservation of Information. The Certificate Trustee shall
preserve, in as current a form as is reasonably practicable, the names and
addresses of Certificateholders contained in the most recent list furnished to
the Certificate Trustee as provided in Section 6.11 or Section 2.07(a), as the
case may be, and the names and addresses of Certificateholders received


                                       19
<PAGE>   24
by the Certificate Trustee in its capacity as Certificate Registrar, if so
acting. The Certificate Trustee may destroy any list furnished to it as provided
in Section 6.11 or Section 2.07(a), as the case may be, upon receipt of a new
list so furnished.

         (c) Communications Among Certificateholders. Certificateholders may
communicate pursuant to Section 312(b) of the Trust Indenture Act with other
Certificateholders with respect to their rights under this Certificate Indenture
or under the Certificates.

         (d) Reports by Certificate Trustee. To the extent that any of the
events described in Section 313(a) of the Trust Indenture Act shall have
occurred, within 60 days after December 31 of each year, commencing with the
year 1999, the Certificate Trustee shall transmit to the Certificateholders, as
provided in Section 313(c) of the Trust Indenture Act, a brief report dated as
of such December 31, if required by Section 313(a) of the Trust Indenture Act.
The Certificate Trustee also shall comply with Section 313(b) of the Trust
Indenture Act.

         A copy of each report at the time of its mailing to Certificateholders
shall be filed by the Certificate Trustee with the Commission and with each
stock exchange, if any, on which the Certificates are listed and of which
listing the Certificate Trustee has been informed. The Certificate Issuer shall
notify the Certificate Trustee if and when the Certificates are listed on any
stock exchange.

         (e) Reports by the Certificate Issuer. Pursuant to Section 314(a)(4) of
the Trust Indenture Act, the Certificate Issuer shall furnish to the Certificate
Trustee, not less often than annually and prior to January 31 of each year,
commencing January 31, 2000, a certificate prepared by the Delaware Trustee on
behalf of the Certificate Issuer as to the Certificate Issuer's compliance with
all conditions and covenants under this Certificate Indenture. For purposes of
this Section 2.07(e), such compliance shall be determined without regard to any
period of grace or requirement of notice provided under this Certificate
Indenture. In addition, the Certificate Trustee shall forward such Certificate
to the Certificateholders.

         (f) Protections. The Certificate Issuer, the Certificate Trustee and
the Certificate Registrar shall have the protection of Section 312(c) of the
Trust Indenture Act.

         Section 2.08. Mutilated, Destroyed, Lost or Stolen Certificates. If (a)
any mutilated Certificate is surrendered to the Certificate Registrar, or the
Certificate Registrar receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (b) there is delivered to the Certificate
Registrar and the Certificate Trustee such security, indemnity or bond as may be
required by them to save each of them harmless, then, in the absence of notice
to the Certificate Registrar or the Certificate Trustee that such Certificate
has been acquired by a bona fide purchaser, the Delaware Trustee, on behalf of
the Certificate Issuer shall execute, and the Certificate Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate (of the same Class as
the Certificate so mutilated, destroyed, lost or stolen) of like Original
Principal Amount. In connection with the issuance of any new Certificate under
this Section 2.08, the Certificate Trustee shall require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and


                                       20
<PAGE>   25
expenses of the Certificate Trustee and the Certificate Registrar) connected
therewith. Any duplicate Certificate issued pursuant to this Section 2.08 shall
constitute conclusive evidence of the same interest in the Certificate Issuer,
as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

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

         Section 2.09. Persons Deemed Owners. Prior to due presentation of a
Certificate for registration of transfer, the Certificate Trustee, the
Certificate Registrar and any Paying Agent of the Certificate Trustee may treat
the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions pursuant to Section 4.02
and for all other purposes whatsoever, and none of the Certificate Trustee, the
Certificate Registrar nor any Paying Agent of the Certificate Trustee shall be
affected by any notice to the contrary.

         Section 2.10. Cancellation. All Certificates surrendered for payment or
transfer or exchange shall, if surrendered to any party hereto other than the
Certificate Registrar, be delivered to the Certificate Registrar for
cancellation. No Certificates shall be authenticated in lieu of or in exchange
for any Certificates cancelled as provided in this Section, except as expressly
permitted by this Certificate Indenture. All cancelled Certificates held by the
Certificate Registrar shall be delivered to the Certificate Trustee and, in
accordance with Section 2.06, destroyed.

         Section 2.11. Limitation of Liability for Payments. All payments or
distributions made to Holders of Certificates under this Certificate Indenture
shall be made only from the Trust Property with respect to that Class of
Certificates and only to the extent that the Certificate Trustee shall have
sufficient income or proceeds from such Trust Property to make such payments in
accordance with the terms of Article IV of this Certificate Indenture. Each
Holder of a Certificate of any Class, by its acceptance of a Certificate of that
Class, agrees that it will look solely to the income and proceeds from the Trust
Property with respect to that Class to the extent available for distribution to
the Holder thereof as provided in this Certificate Indenture. It is expressly
understood and agreed by the parties hereto that (a) the Certificates are
executed, authenticated and delivered by the Delaware Trustee and the
Certificate Trustee, respectively, not individually or personally but solely in
their respective capacity as Delaware Trustee and Certificate Trustee in the
exercise of the powers and authority conferred and vested in them, and (b) under
no circumstances shall the Delaware Trustee or Certificate Trustee be personally
liable for the payment of any of the Certificates or any indebtedness or
expenses of the Trust or be liable for the breach or failure of any obligation,
representation, warranty or covenant made or undertaken by the Certificate
Issuer under this Certificate Indenture.

         Section 2.12. Book-Entry and Definitive Certificates.

         (a) The Certificates of any Class may be issued in the form of one or
more typewritten certificates representing the Book-Entry Certificates of that
Class, to be delivered to The Depository Trust Company, the initial Clearing
Agency, by, or on behalf of, the Certificate Issuer. In such case, the
Certificates of such Class delivered to The Depository Trust Company shall
initially be registered on the Certificate Register in the name of Cede & Co.,
the nominee of the initial Clearing Agency, and no Certificate Owner will
receive a definitive Certificate representing such Certificate Owner's interest
in the Certificate of such Class, except as provided in Section 2.12(c) below.
Unless and until definitive, fully registered Certificates ("Definitive
Certificates") of such Class have been issued pursuant to Section 2.12(c) below:

                  (i) the provisions of this Section 2.12 shall be in full force
         and effect with respect to the Certificates of such Class;

                  (ii) the Certificate Issuer, the Paying Agent, the Certificate
         Registrar and the Certificate Trustee may deal with the Clearing Agency
         for all purposes (including the making of distributions on the
         Certificates of such Class) as the authorized representative of the
         Certificate Owners of Certificates of such Class;

                  (iii) to the extent that the provisions of this Section 2.12
         conflict with any other provisions of this Certificate Indenture, the
         provisions of this Section 2.12 shall control;

                  (iv) the rights of Certificate Owners of Certificates of such
         Class shall be exercised only through the Clearing Agency and shall be
         limited to those established by law and agreements between such
         Certificate Owners and the Clearing Agency Participants; and until
         Definitive Certificates of such Class are issued pursuant to Section
         2.12(c) below, the Clearing Agency will make book-entry transfers among
         the Clearing Agency Participants and receive and transmit distributions
         of principal of and interest on the Certificates of such Class to such
         Clearing Agency Participants; and

                  (v) whenever this Certificate Indenture requires or permits
         actions to be taken based upon instructions or directions of
         Certificateholders holding Certificates of such Class representing a
         specified percentage of the aggregate Outstanding Amount of
         Certificates of such Class, the Clearing Agency shall be deemed to
         represent such percentage only to the extent that it has received
         instructions to such effect from Certificate Owners or Clearing Agency
         Participants owning or representing, respectively, Certificates
         representing such percentage of the aggregate Outstanding Amount of
         Certificates of such Class, and has delivered such instructions to the
         Certificate Trustee; the Certificate Trustee shall have no obligation
         to determine whether the Clearing Agency has in fact received any such
         instructions.

         (b) Whenever notice or other communication to the Holders of
Certificates of any Class issued in the form of Certificates representing
Book-Entry Certificates is required under this Certificate Indenture, unless and
until Definitive Certificates of such Class shall have been issued


                                       22
<PAGE>   27
pursuant to Section 2.12(c), the Certificate Trustee shall give all such notices
and communications specified herein to be given to Holders of Certificates of
such Class to the Clearing Agency.

         (c) If (i) the Clearing Agency advises the Certificate Trustee in
writing that the Clearing Agency is no longer willing or able to properly
discharge its responsibilities with respect to the Certificates of a Class, and
the Certificate Trustee or the Certificate Issuer is unable to locate a
qualified successor, (ii) the Certificate Issuer (with the prior written
approval of the Note Issuer) at its option advises the Certificate Trustee in
writing that it elects to terminate the book-entry system through the Clearing
Agency with respect to the Certificates of such Class or (iii) after the
occurrence of a Note Event of Default with respect to any Class of Certificates,
Certificate Owners representing beneficial interests aggregating at least a
majority of the Outstanding Amount of the Certificates advise the Clearing
Agency and the Certificate Trustee in writing that the continuation of a
book-entry system through the Clearing Agency is no longer in the best interests
of the Certificate Owners, then the Clearing Agency shall notify all Certificate
Owners and the Certificate Trustee of the occurrence of any such event and of
the availability of Definitive Certificates to Certificate Owners requesting the
same. Upon surrender to the Certificate Trustee of the typewritten certificate
or certificates representing the Book-Entry Certificates by the Clearing Agency,
accompanied by registration instructions, and upon written direction by the
Certificate Issuer, the Delaware Trustee shall execute on behalf of the
Certificate Issuer and the Certificate Trustee shall authenticate the Definitive
Certificates in accordance with the instructions of the Clearing Agency. None of
the Certificate Issuer, the Certificate Registrar or the Certificate Trustee
shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be fully protected in relying on, such
instructions. Upon the issuance of Definitive Certificates, the Certificate
Trustee shall recognize the Holders of the Definitive Certificates as
Certificateholders.

         Section 2.13. Tax Treatment.

         (a) It is the intention of the parties hereto that the Certificate
Issuer shall be treated as a "grantor trust" for federal income tax purposes and
all transactions contemplated by this Certificate Indenture will be reported
consistent with such treatment.

         (b) The provisions of this Certificate Indenture shall be construed,
and the affairs of the Certificate Indenture shall be conducted, so as to
achieve treatment of the Certificate Indenture as a "grantor trust" for federal
income tax purposes.

                                    COVENANTS

         Section 3.01. Compliance with Declaration of Trust. The Certificate
Issuer covenants and agrees to operate in strict conformity with the Declaration
of Trust, the terms of which are incorporated herein by reference, and shall not
amend the Declaration of Trust except as expressly permitted thereunder or in
any manner that would adversely affect the interests of the Certificateholders.

         This Certificate Indenture and the Declaration of Trust shall,
together, constitute the governing instrument of the Trust. To the extent that

conflict with respect to the issuance of the Certificates and the rights of the
holders thereof, this Certificate Indenture shall control.

not issue any additional Certificates hereunder, except pursuant to Section 2.06
and Section 2.08.

         Section 4.01. Certificate Accounts.

         (a) The Certificate Trustee shall establish and maintain, for the
Certificate Issuer, on behalf of the Holders of Certificates of each Class one
or more segregated trust accounts with respect to such Class (each, a
"Certificate Account"), which shall be non-interest bearing except as provided
in Section 4.04, in the corporate trust department of an Eligible Institution,
in the name of the Certificate Trustee for the benefit of such
Certificateholders. The Certificate Trustee shall hold each Certificate Account
in trust for the benefit of the Holders of Certificates of the corresponding
Class, and shall make or permit withdrawals therefrom only as provided in this
Certificate Indenture. On each day when a Payment or Special Payment (other than
a Special Payment that represents the proceeds of any sale pursuant to Article V
hereof by the Certificate Trustee of any Note) is made to the Certificate
Trustee, as holder of Notes of any Class, the Certificate Trustee upon receipt
shall immediately deposit the aggregate amount of such Payment or Special
Payment in the Certificate Account for the corresponding Class of Certificates.
Upon the sale of any Note by the Certificate Trustee pursuant to Article V and
the realization of any proceeds thereof, the Certificate Trustee shall deposit
the aggregate amount of such proceeds as a Special Payment in the Certificate
Account for the Class of Certificates corresponding to the Class of the Note so
sold.

         (b) The Certificate Trustee shall present to the Note Trustee for
payment each Note on its Final Maturity Date, or, in the case of any redemption
or repayment of such Note in full prior to its Final Maturity Date, on the
applicable Payment Date therefor.

         (c) The Certificate Trustee (or any Paying Agent other than the
Certificate Trustee) shall have sole dominion and exclusive control over all
monies in the Certificate Accounts and shall apply such amounts therein as
provided in this Article.

         Section 4.02. Distributions from Certificate Accounts.

         (a) On any Distribution Date, the Certificate Trustee shall distribute
out of the Certificate Account for the corresponding Class of Certificates, in
the manner described in Section 4.02(e), the entire amount of such Payment
deposited therein pursuant to Section 4.01(a); provided, however, that in the
event receipt of any such Payment is not confirmed by the Certificate Trustee by
1:00 p.m. (New York City time) on such Distribution Date, distribution thereof
shall


                                       24
<PAGE>   29
be made on the day receipt thereof is confirmed by the Certificate Trustee by
1:00 p.m. (New York City time) or, if receipt thereof is confirmed by the
Certificate Trustee after 1:00 p.m. (New York City time), on the following
Business Day. There shall be so distributed to each Holder of such Class of
Certificates on the Record Date with respect to such Distribution Date (other
than as provided in Section 9.01 with respect to a final distribution) such
Certificateholder's fractional undivided share (based on the aggregate
Outstanding Amount of Certificates of such Class held by such Certificateholder)
of the aggregate amount in the related Certificate Account. The foregoing
notwithstanding, if a Payment is not received by the Certificate Trustee by the
day that is five days after the related Payment Date, but is subsequently
received, it will be treated as a Special Payment pursuant to Section 4.02(b).

         The final distribution with respect to any Certificate, however, will
be made only upon presentation and surrender of such Certificate at the office
or agency of the Certificate Trustee specified in the notice given by the
Certificate Trustee with respect to such final payment. The Certificate Trustee
will provide notice of a final distribution to each Holder as of the date such
notice is given with respect to any Certificate as soon as practicable following
receipt of notice from the Note Trustee of a final payment on a corresponding
Note.

         (b) On each Special Distribution Date with respect to the distribution
of any Special Payment with respect to any Class of Notes, the Certificate
Trustee shall distribute out of the Certificate Account for the corresponding
Class of Certificates, in the manner described in Section 4.02(e), the entire
amount of such Special Payment deposited therein pursuant to Section 4.01(a) and
any income and earnings received from the investment of such Special Payment
pursuant to Section 4.04; provided, however, that in the event receipt of any
such Special Payment is not confirmed by the Certificate Trustee by 1:00 p.m.
(New York City time) on such Special Distribution Date, distribution thereof
shall be made on the day receipt thereof is confirmed by the Certificate Trustee
by 1:00 p.m. (New York City time) or, if receipt thereof is confirmed by the
Certificate Trustee after 1:00 p.m. (New York City time), on the following
Business Day. There shall be so distributed to each Holder of such Class of
Certificates on the Special Record Date with respect to such Special
Distribution Date (other than as provided in Section 9.01 with respect to a
final distribution) such Certificateholder's fractional undivided share (based
on the aggregate Outstanding Amount of Certificates of such Class held by such
Certificateholder) of the aggregate amount of such Special Payment and any
income and earnings received from the investment of such Special Payment
pursuant to Section 4.04.

         (c) The Certificate Trustee shall allocate amounts distributed to
Holders of Certificates of any Class on any Distribution Date or Special
Distribution Date as follows: (i) to the extent such amounts represent payments
of principal of the corresponding Class of Notes (including prepayments or
redemption price), or the proceeds of the sale of any such Note by the
Certificate Trustee pursuant to Article V (to the extent such proceeds exceed
the unpaid interest on the related class of Notes), such amounts shall be
allocated to principal of such Certificates and (ii) all other such amounts
shall be allocated to interest on such Certificates. The Certificate Trustee may
conclusively rely on the payment statement received by it from the Servicer
pursuant to the Servicing Agreement with any payment in respect of any Class of
Notes as to whether the amount so paid in respect of such Notes is in respect of
principal of or interest on


                                       25
<PAGE>   30
such Notes. If no statement is received, such payments received with respect to
any Class of Notes shall first be allocable to interest to the extent of any
interest accrued and payable on such Class of Notes, and then to principal.

         (d) The Certificate Trustee shall cause notice of each Special Payment
with respect to any Class of Notes to be mailed to each Holder of Certificates
of the corresponding Class at its address as it appears in the Certificate
Register. In the event of (i) the optional redemption of the Notes of any Class,
such notice shall be mailed not less than five days nor more than 25 days prior
to the Special Distribution Date on which any such Redemption Payment is
scheduled to be distributed, and (ii) the mandatory redemption of the Notes of
any Class, such notice shall be mailed not less than five days prior to the
Special Distribution Date on which any such Redemption Payment is scheduled to
be distributed. In the case of any other Special Payment, such notice shall be
mailed not less than 20 days prior to the Special Distribution Date on which any
Special Payment is scheduled to be distributed in respect of Certificates of
such Class stating such anticipated Special Distribution Date. Any such notice
mailed by the Certificate Trustee shall set forth:

                  (i) the Special Distribution Date or the Distribution Date, as
         applicable, and the Special Record Date or Record Date therefor, as
         applicable (except as otherwise provided in Section 9.01);

                  (ii) the amount of the Special Distribution for each $1,000
         Original Principal Amount of Certificates of the applicable Class and
         the amount thereof constituting principal and interest;

                  (iii) the reason for the Special Distribution; and

                  (iv) the total amount to be received on such date for each
         $1,000 Original Principal Amount of Certificates of the applicable
         Class but only, in the case of a Special Payment, if the related
         Special Distribution Date is also a Distribution Date.

         (e) Distributions to Holders of Certificates shall be by check sent by
first-class mail to the address of such Holder appearing on the Certificate
Register at the relevant Record Date or Special Record Date or, upon written
application of a Holder of Certificates of any Class in the Original Principal
Amount of $1,000,000 or more to the Certificate Trustee made at any time not
later than such Record Date or Special Record Date or continuing in effect from
a prior request, by wire transfer in immediately available funds to the account
of such Holder at such bank located in New York, New York having wire transfer
capability as may be designated by such Holder; provided, however, that the
final distribution in respect of any Certificate shall be made only as provided
in Section 9.01. The foregoing notwithstanding, any distributions made to Cede &
Co., as the nominee of the initial Clearing Agency, shall be made by wire
transfer of immediately available funds.

         Section 4.03. Statements to Certificateholders.

         (a) On each Distribution Date, Special Distribution Date or any other
date specified herein for distribution of any payments with respect to any Class
of Certificates, or as soon as practicable following such Distribution Date,
Special Distribution Date or other date (unless the Certificate Trustee is the
Note Trustee and the statement required below is provided by the Note Trustee no
later than two Business Days prior to such distribution), the Certificate
Trustee will send, with respect to each distribution, to Holders of Certificates
of such Class a statement with respect to such distribution to be made on such
Distribution Date, Special Distribution Date or other date, as the case may be,
setting forth the following information:

                  (i) the amount of such distribution to Holders of Certificates
         allocable to (A) principal and (B) interest, in each case per $1,000
         Original Principal Amount of each Class of Certificates;

                  (ii) the aggregate outstanding principal balance of the
         Certificates, after giving effect to payments allocated to principal
         reported under (i) above; and

                  (iii) the difference, if any, between the amount specified in
         (ii) above and the principal amount scheduled to be outstanding on such
         date according to the Expected Amortization Schedule.

In providing the foregoing statement, the Certificate Trustee may rely upon the
statements provided by the Note Trustee pursuant to Section 6.06 of the Note
Indenture. On each date on which the Certificate Trustee distributes any such
report to the Holders of the Certificates of any Class, the Certificate Trustee
shall also distribute such report to each Rating Agency.

         (b) Within a reasonable period of time after the end of each calendar
year but not later than the latest date permitted by law, the Certificate
Trustee shall furnish to each Person who at any time during such calendar year
was a Holder of any Class of Certificates and received a distribution thereon, a
statement containing the sum of the amounts determined pursuant to clause (a)
(i) above with respect to such Class of Certificates for such calendar year, or,
in the event such Person was a Holder of such Class of Certificates during a
portion of such calendar year, for the applicable portion of such year, and such
other items as are readily available to the Certificate Trustee and that a
Certificateholder shall reasonably request as necessary for the purpose of such
Certificateholder's preparation of its federal income tax returns.

         Section 4.04. Investment of Special Payment Moneys. Any money received
by the Certificate Trustee pursuant to Section 4.01(a) representing a Special
Payment that is not to be promptly distributed, to the extent practicable, shall
be invested in Eligible Investments at the written direction of the Servicer by
the Certificate Trustee pending distribution of such Special Payment pursuant to
Section 4.02. Any investment made pursuant to this Section 4.04 shall be in such
Eligible Investments maturing in not more than 60 days or such lesser time as is
required for the distribution of any such funds on a Special Distribution Date
pending the distribution of such funds to Certificateholders as described
herein. The Certificate Trustee shall hold any such Eligible Investments until
maturity. Such Eligible Investments (i) shall not mature later than the

                                       27
<PAGE>   32
Business Day immediately preceding the Special Distribution Date relating to
such invested funds, (ii) (A) if such Eligible Investments have a maturity of
one month or less, such Eligible Investments (or the provider thereof) must have
a long term unsecured debt rating of at least A2 by Moody's or a certificate of
deposit rating of at least P-1 by Moody's, and (B) if such Eligible Investments
have a maturity of greater than one month, such Eligible Investments (or the
provider thereof) must have a long term unsecured debt rating of at least Aaa by
Moody's and a certificate of deposit rating of at least P-1 by Moody's. The
Certificate Trustee shall have no liability with respect to any investment made
pursuant to this Section 4.04 (including any losses on such investments), other
than by reason of the willful misconduct or gross negligence of the Certificate
Trustee. All income and earnings from such investments shall be distributed, if
and as received, on such Special Distribution Date as part of such Special
Payment and shall be treated as payments of interest on the Certificates.

         If the rating of the Eligible Institution, which may be the Note
Trustee's Corporate Trust Office, fall below the rating requirements set forth
in clause (b)(i) of the definition of Eligible Institution, the Delaware
Trustee, on behalf of the Certificate Issuer, shall, within one month after
notice of such rating change, cause the Collection Account to be transferred to
an institution meeting the requirements set forth in clause (b)(i) of the
definition of Eligible Institution.

         Section 4.05. Reduction in Principal. Any reduction in the principal
amount of any Certificate effected by any distribution in respect of principal
thereof shall be binding upon all Holders of such Certificate and of any
Certificate issued upon the registration or transfer thereof or in lieu thereof,
whether or not noted thereon.

                                   ARTICLE V

                                    DEFAULTS

         Section 5.01. Events of Default.

         (a) If any Event of Default, other than a breach of the Commonwealth
Pledge by The Commonwealth of Massachusetts under the Statute and Section 10.01
hereunder, shall occur and be continuing, then, and in each and every case, the
Certificate Trustee may, and, upon the written direction of Holders representing
not less than a majority of the Outstanding Amount of the Certificates then
Outstanding, shall vote all the Notes in favor of declaring the unpaid principal
amount of all the Notes then outstanding and accrued interest thereon to be due
and payable in accordance with the provisions thereof. In addition, if a Note
Event of Default shall have occurred and be continuing, the Certificate Trustee
may, and, upon the written direction of Holders representing not less than a
majority of the Outstanding Amount of the Certificates then Outstanding, shall
vote all the Notes in favor of directing the Note Trustee as to the time, method
and place of conducting any proceeding for any remedy available to the Note
Trustee, including the sale of any or all of the Notes, without recourse to or
warranty by the Certificate Trustee or any Certificateholder, to any person or
entity, or of exercising any trust or power conferred on the Note Trustee under
the Note Indenture.

                                       28
<PAGE>   33
         (b) In addition, after a Note Event of Default shall have occurred and
be continuing, subject to Section 5.01(c), the Certificate Trustee may, and upon
the written direction of Holders of Certificates representing not less than a
majority of the Outstanding Amount of Certificates, by such officer or agent as
it may appoint, shall sell, convey, transfer and deliver any Note or Notes,
without recourse to or warranty by the Certificate Trustee or any
Certificateholder, to any Person, all upon such terms and conditions as the
Certificateholders may reasonably deem advisable and at such prices as the
Certificateholders may reasonably deem advisable, for cash. If the Certificate
Trustee so decides or is required to sell or otherwise dispose of the Notes
pursuant to this Section, the Certificate Trustee may, but is not obligated to,
take such of the actions described above as it may reasonably deem most
effectual to complete the sale or other disposition of the Notes, so as to
provide for the payment in full of all amounts due on the Certificates.

         (c) The foregoing provisions of Section 5.01(b) notwithstanding, the
Certificate Trustee shall not sell any Notes following the occurrence of any
Event of Default, other than a Note Event of Default described in Section
5.01(i), (ii) or (iii) of the Note Indenture, unless (i) the Certificate Trustee
determines that the amounts receivable from the Collateral are not sufficient to
pay in full the principal of and accrued interest on the Notes and all amounts
payable pursuant to clauses (i) through (iv) of Section 8.02(d) of the Note
Indenture and the Certificate Trustee obtains the written consent of Holders of
Certificates of each Class representing 66 2/3 percent of the aggregate
Outstanding Amount of the Certificates, or (ii) the Certificate Trustee obtains
the written consent of Holders of Certificates representing 100 percent of the
aggregate Outstanding Amount of the Certificates.

         Section 5.02. Incidents of Sale of Notes. Upon any sale of the Notes
made either under the power of sale given under this Certificate Indenture or
otherwise for the enforcement of this Certificate Indenture, the following shall
be applicable:

                  (a) Certificateholders and Certificate Trustee May Purchase
         Notes. Any Certificateholder, the Certificate Trustee in its individual
         or any other capacity or any other Person (other than the Seller) may
         bid for and purchase any of the Notes, and upon compliance with the
         terms of sale, may hold, retain, possess and dispose of such Notes in
         their own absolute right without further accountability.

                  (b) Receipt of Certificate Trustee Shall Discharge Purchaser.
         The receipt of the Certificate Trustee, on behalf of the Certificate
         Issuer, shall be a sufficient discharge to any purchaser for its
         purchase money, and, after paying such purchase money and receiving
         such receipt, such purchaser or its personal representative or assigns
         shall not be obliged to see to the application of such purchase money,
         or be in any way answerable for any loss, misapplication or
         nonapplication thereof.

                  (c) Application of Moneys Received upon Sale. Any moneys
         collected by the Certificate Issuer or the Certificate Trustee upon any
         sale made either under the power of sale given by this Certificate
         Indenture or otherwise for the enforcement of this Certificate
         Indenture, shall be applied as provided in Section 4.02.

         Section 5.03. Judicial Proceedings Instituted by Certificate Trustee;
Certificate Trustee May Bring Suit.

         (a) If there shall be a failure to make payment of the principal of or
interest on any Note, then the Certificate Trustee in its own name, and as
trustee of an express trust, as holder of such Note, if directed in writing by
the Holders of a majority of the Outstanding Amount of the Certificates but
subject to the provisions of Article VI, shall, to the extent permitted by and
in accordance with the terms of the Notes, be entitled and empowered to
institute any suits, actions or proceedings at law, in equity or otherwise,
including the power to make a demand on the Note Trustee to take action under
the Note Indenture to enforce the Notes, for the collection of the sums so due
and unpaid on the Note and may prosecute any such claim or proceeding to
judgment or final decree with respect to the whole amount of any such sums so
due and unpaid.

         (b) If there shall be a breach of the Commonwealth Pledge by The
Commonwealth of Massachusetts, then the Certificate Trustee, in its own name and
as trustee of an express trust, as holder of the Notes, shall be, to the extent
permitted by state and federal law, entitled and empowered to institute any
suits, actions or proceedings at law, in equity or otherwise, to enforce the
Commonwealth Pledge and to collect any monetary damages as a result of a breach
thereof, and may prosecute any such suit, action or proceeding to judgment or
final decree.

         Section 5.04. Control by Certificateholders. The Holders of a majority
of the Outstanding Amount of the Certificates (or, if less than all Classes are
affected, the affected Class or Classes) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Certificate Trustee, or exercising any trust or power conferred on the
Certificate Trustee under this Certificate Indenture, including any right of the
Certificate Trustee as holder of the Notes of the corresponding Class or
Classes, in each case unless a different percentage is specified herein;
provided, however, that:

                  (a) such direction shall not be in conflict with any rule of
         law or with this Certificate Indenture and would not involve the
         Certificate Trustee in personal liability or expense;

                  (b) the Certificate Trustee shall not determine that the
         action so directed would be unjustly prejudicial to the Holders of
         Certificates of such Class or Classes not taking part in such
         direction;

                  (c) the Certificate Trustee may take any other action deemed
         proper by the Certificate Trustee that is not inconsistent with such
         direction; and

                  (d) if a Note Event of Default with respect to such Class of
         Notes shall have occurred and be continuing, such direction shall not
         obligate the Certificate Trustee to vote more than a corresponding
         majority of the related Notes held by the Certificate Issuer in favor
         of declaring the unpaid principal amount of the Notes and accrued
         interest thereon to be due and payable or directing any action by the
         Note Trustee with respect to such Note Event of Default.

<PAGE>   35
         Section 5.05. Waiver of Past Defaults. Prior to the declaration of the
acceleration of the maturity of the Notes as provided in Section 5.01, the
Holders of Certificates of not less than a majority of the Outstanding Amount of
the Certificates may waive any past default or Note Event of Default and its
consequences except a default (a) in payment of principal of or interest on any
of the Notes, (b) in respect of a covenant or provision under the Note Indenture
that cannot be modified or amended without the consent of the Holder of each
Certificate or Classes affected or (c) in the deposit or distribution of any
Payment or Special Payment under Section 4.01 or in the distribution of any
payment under Section 4.02. Upon any such direction, the Certificate Trustee
shall vote such percentage of the Notes of the corresponding Class held by the
Certificate Trustee as corresponds to the percentage of the aggregate
Outstanding Amount of the Certificates of such Class held by Holders who
directed the Certificate Trustee to waive such default or Note Event of Default
hereunder.

         Upon any waiver that is effective under the terms of the Note Indenture
to waive such Note Event of Default, such Note Event of Default shall cease to
exist with respect to this Certificate Indenture, and, in the case of a default,
any Note Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Certificate Indenture and any written direction given
by the Certificate Trustee on behalf of such Certificateholders to the Note
Trustee or in respect of any Notes shall be annulled with respect thereto; but
no such waiver shall extend to any subsequent or other default or Note Event of
Default or impair any right consequent thereon.

         Section 5.06. Right of Certificateholders To Receive Payments Not To Be
Impaired. Anything in this Certificate Indenture to the contrary
notwithstanding, including Section 5.07 hereof, the right of any
Certificateholder to receive distributions of payments required pursuant to
Section 4.02 hereof on the Certificates when due, or to institute suit for the
enforcement of any such payment on or after the applicable Distribution Date,
Special Distribution Date or other date specified herein for the making of such
payment, shall not be impaired or affected without the consent of such
Certificateholder.

         Section 5.07. Certificateholders May Not Bring Suit Except Under
Certain Conditions. A Certificateholder shall not have the right to institute
any suit, action or proceeding at law or in equity or otherwise with respect to
this Certificate Indenture, for the appointment of a receiver or for the
enforcement of any other remedy under this Certificate Indenture, unless:

                  (a) such Certificateholder has previously given written notice
         to the Certificate Trustee of a continuing Note Event of Default with
         respect to the Class of Certificates held by such Holder;

                  (b) the Holders of not less than 25 percent of the Outstanding
         Amount of the Certificates have made written request to the Certificate
         Trustee to institute such action, suit or proceeding in respect of such
         Note Event of Default in its own name as Certificate Trustee hereunder;

                                       31
<PAGE>   36
                  (c) such Certificateholder or Certificateholders have offered
         to the Certificate Trustee indemnity satisfactory to it against the
         costs, expenses (including legal fees and expenses) and liabilities to
         be incurred in complying with such request;

                  (d) the Certificate Trustee for 60 days after its receipt of
         such notice, request and offer of indemnity has failed to institute
         such action, suit or proceedings; and

                  (e) no direction inconsistent with such written request has
         been given to the Certificate Trustee during such 60-day period by the
         Holders of a majority of the Outstanding Amount of the Certificates;

it being understood and intended that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue of, or by availing of, any
provision of this Certificate Indenture to affect, disturb or prejudice the
rights of any other Holders of Certificates or to obtain or to seek to obtain
priority or preference over any other Certificateholders or to enforce any right
under this Certificate Indenture, except in the manner herein provided. The
provisions of this Section 5.07 shall be deemed to modify, to the fullest extent
permitted by law, the rights of the Certificateholders under Section 3816 of the
Business Trust Statute.

         In the event the Certificate Trustee shall receive conflicting or
inconsistent requests and indemnity from two or more groups of Holders of
Certificates, each representing less than a majority of the Outstanding Amount
of the Certificates, the Certificate Trustee in its sole discretion may
determine what action, if any, shall be taken, notwithstanding any other
provisions of this Certificate Indenture.

         Section 5.08. Remedies Cumulative. No remedy given hereunder to the
Certificate Trustee or to any of the Certificateholders shall be exclusive of
any other remedy or remedies, and every such remedy shall be cumulative and in
addition to every other remedy given hereunder or now or hereafter given by
statute, law, equity or otherwise.

                             THE CERTIFICATE TRUSTEE

         Section 6.01. Notice of Defaults. As promptly as practicable after, and
in any event within 30 days after, receipt by a Responsible Officer of the
Certificate Trustee of written notice or actual knowledge of the occurrence of
any default (as such term is defined below) hereunder, the Certificate Trustee
shall transmit by mail to the Certificate Issuer, the Note Trustee and the
Holders of Certificates in accordance with Section 313(c) of the Trust Indenture
Act, notice of such default, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default hereunder with
respect to any Class of Certificates arising from a default under the Note
Indenture in the payment of the principal of or interest on any Note, the
Certificate Trustee shall be fully protected in withholding such notice if and
so long as a trust committee of Responsible Officers of the Certificate Trustee
in good faith determines that the withholding of such notice is in the interests
of the Holders of the Certificates. For the purpose

                                       32
<PAGE>   37
of this Section, the term "default" means any event that is, or after notice or
lapse of time or both would become, a Note Event of Default with respect to such
Class of Certificates.

         Section 6.02 Certain Rights of Certificate Trustee. Subject to the
provisions of Section 315 of the Trust Indenture Act:

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

                  (b) any request or direction of the Certificate Issuer
         mentioned herein shall be sufficiently evidenced by a Request,
         accompanied by evidence reasonably satisfactory to the Certificate
         Trustee that the Note Issuer has given its prior written approval of
         such request or direction;

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

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

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

                  (f) the Certificate Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or document;

                  (g) the Certificate Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through agents, attorneys, custodians or nominees and the
         Certificate Trustee shall not be responsible for any misconduct or
         negligence on the part of, or for the supervision of, any agent,
         attorney, custodian or nominee appointed with due care by it hereunder;

                                       33
<PAGE>   38
                  (h) the Certificate 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 Holders of Certificates relating
         to the time, method and place of conducting any proceeding for any
         remedy available to the Certificate Trustee, or exercising any trust or
         power conferred upon the Certificate Trustee, under this Certificate
         Indenture;

                  (i) the Certificate Trustee shall not be required to expend or
         risk its own funds in the performance of any of its duties hereunder,
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that repayment of such funds or
         indemnity satisfactory to it against such risk is not reasonably
         assured to it;

                  (j) the Certificate Trustee shall not be personally liable for
         any action taken or suffered or omitted to be taken by it in good faith
         and reasonably believed by it to be authorized or within the discretion
         or rights or powers conferred upon it by this Certificate Indenture;
         provided, however, that the Certificate Trustee's conduct does not
         constitute willful misconduct, gross negligence or bad faith;

                  (k) in the event that the Certificate Trustee is also acting
         as Paying Agent, Authenticating Agent or Certificate Registrar
         hereunder, the rights and protections afforded to the Certificate
         Trustee pursuant to this Article VI shall also be afforded to such
         Paying Agent, Authenticating Agent or Certificate Registrar;

                  (l) the Certificate Trustee shall not be charged with
         knowledge of an Event of Default unless a Responsible Officer obtains
         actual knowledge of such event or the Certificate Trustee receives
         written notice of such event from the Certificate Issuer, the Note
         Trustee, the Servicer or a majority of the Holders of Certificates of
         the Class or Classes so affected; and

                  (m) without limiting its rights under bankruptcy law, when the
         Certificate Trustee incurs expenses or renders services in connection
         with the insolvency or bankruptcy of any party hereto or with the Basic
         Documents to which it is a party, such expenses (including the fees and
         expenses of its counsel) and the compensation for such services are
         intended to constitute expenses of administration under any bankruptcy
         or insolvency law.

         Section 6.03. Not Responsible for Recitals or Issuance of Certificates.
The recitals contained herein and in the Certificates, except the execution
thereof and the certificates of authentication, shall not be taken as the
statements of the Certificate Trustee, and the Certificate Trustee assumes no
responsibility for their correctness. Except as set forth in Section 6.14, the
Certificate Trustee makes no representations as to the validity or sufficiency
of this Certificate Indenture, the Notes, any Basic Document or the
Certificates.

         Section 6.04. May Hold Certificates. The Certificate Trustee, any
Paying Agent, any Certificate Registrar or any of their Affiliates or any other
agent, in their respective individual or any other capacity, may become the
owner or pledgee of Certificates and, subject to Sections 310(b) and 311 of the
Trust Indenture Act, may otherwise deal with the Certificate Issuer, the Note
Issuer or

                                       34
<PAGE>   39
the Note Trustee with the same rights it would have if it were not Certificate
Trustee, Paying Agent, Certificate Registrar or such other agent.

         Section 6.05. Money Held in Trust. Money held by the Certificate
Trustee or the Paying Agent in trust hereunder need not be segregated from other
funds except to the extent required herein or by law and neither the Certificate
Trustee nor the Paying Agent shall have any liability for interest upon any such
moneys except as provided for herein.

         Section 6.06. Compensation and Reimbursement; Indemnification.

         (a) Pursuant to the Fee and Indemnity Agreement, the Note Issuer has
agreed to pay, or cause to be paid, to the Certificate Trustee from time to time
reasonable compensation for its services and to reimburse it for its reasonable
expenses.

         (b) Pursuant to the Fee and Indemnity Agreement, the Note Issuer shall
indemnify, defend and hold harmless the Certificate Trustee and any of the
affiliates, officers, directors, employees and agents of the Certificate Trustee
(the "Certificate Trustee Indemnified Persons") from and against any and all
losses, claims, actions, suits, taxes, damages, expenses and liabilities
(including liabilities under state or federal securities laws) of any kind and
nature whatsoever (collectively, "Certificate Trustee Expenses"), to the extent
that such Certificate Trustee Expenses arise out of or are imposed upon or
asserted against such Certificate Trustee Indemnified Persons with respect to
the creation, operation or termination of the Certificate Issuer, the execution,
delivery or performance of the Declaration of Trust or this Certificate
Indenture, as the case may be, or the transactions contemplated hereby, the
failure of the Note Issuer or any other person (other than the person being
indemnified) to perform its obligations under the Fee and Indemnity Agreement or
under any of the Basic Documents, or otherwise in connection with the Basic
Documents or the transactions contemplated thereby; provided, however, that the
Note Issuer shall not be required to indemnify any Certificate Trustee
Indemnified Person for any Certificate Trustee Expenses that result from the
willful misconduct or gross negligence of such Certificate Trustee Indemnified
Person. The obligations of the Note Issuer to indemnify the Certificate Trustee
Indemnified Persons shall survive the termination of the Fee and Indemnity
Agreement, this Certificate Indenture and the resignation or removal of the
Certificate Trustee.

         Notwithstanding anything to the contrary in this Certificate Indenture,
the Certificate Trustee shall have no recourse against the Certificate Issuer or
the Notes or payments thereon or proceeds thereof for payment of any amounts
required to be paid to the Certificate Trustee under this Section 6.06(b).

         Section 6.07. Corporate Certificate Trustee Required; Eligibility.

         (a) The Certificate Trustee shall at all times be eligible to act as a
trustee under Section 310(a) of the Trust Indenture Act, shall have a combined
capital and surplus of at least $50,000,000 and shall have a long-term debt
rating of at least A by Moody's and Standard & Poor's. If such entity publishes
reports of conditions at least annually, pursuant to law or to the requirements
of federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 6.07, the combined capital and
surplus of such

                                       35
<PAGE>   40
entity shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published.

         (b) In determining whether the Certificate Trustee has a conflicting
interest under Section 310(b) of the Trust Indenture Act and this Section, each
other Class of Certificates will be treated as having been issued under an
indenture other than this Certificate Indenture.

         (c) If at any time the Certificate Trustee shall cease to be eligible
in accordance with the provisions of this Section 6.07, the Certificate Trustee
shall resign immediately in the manner and with the effect specified in Section
6.08.

         Section 6.08. Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Certificate Trustee and no
appointment of a successor Certificate Trustee pursuant to this Article shall
become effective (i) until the acceptance of appointment by the successor
Certificate Trustee under Section 6.09 and (ii) other than in the case of
paragraph (b) below, unless a successor Certificate Trustee has been appointed
and has accepted such appointment and the Note Issuer and the Certificate Issuer
have received written confirmation from each of the Rating Agencies that no
lowering or withdrawal of the then current ratings of any Class of Certificates
will result from such appointment.

         (b) The Certificate Trustee may resign at any time in the case of a
conflicting interest as determined in accordance with Section 6.07(b) by giving
written notice thereof to the Certificate Issuer, the Authorized Agents, the
Note Issuer and the Note Trustee. If an instrument of acceptance by a successor
Certificate Trustee shall not have been delivered to the Certificate Issuer and
the Certificate Trustee within 30 days after the giving of such notice of
resignation, the resigning Certificate Trustee may petition any court of
competent jurisdiction for the appointment of a successor Certificate Trustee.

         (c) The Certificate Trustee may be removed at any time in the case of a
conflicting interest as determined in accordance with Section 6.07(b) by Act of
Certificateholders holding Certificates representing not less than 51 percent of
the Outstanding Amount of the Certificates delivered to the Certificate Trustee
and to the Certificate Issuer, the Note Issuer and the Note Trustee.

         (d) Upon 30 days' written notice, the Certificate Trustee (i) may
resign with respect to the Certificates as a whole by giving such written notice
to the Certificate Issuer, the Authorized Agents, the Note Issuer and the Note
Trustee or (ii) may be removed with respect to the Certificates as a whole by
Act of Certificateholders holding Certificates representing not less than a
majority of the Outstanding Amount of Certificates delivered to the Certificate
Issuer, the Note Issuer and the Note Trustee. If an instrument of acceptance by
a successor Certificate Trustee with respect to the Certificates as a whole
shall not have been delivered to the Certificate Issuer, the Note Issuer and the
Note Trustee within 90 days after the giving of such notice of resignation or
Act by the Certificateholders as a whole for removal of the Certificate Trustee,
the Certificate Issuer may petition any court of competent jurisdiction for the
appointment of a successor Certificate Trustee with respect to the Certificates
as a whole.

                                       36
<PAGE>   41
         (e) If at any time:

                  (i) the Certificate Trustee shall fail to comply with Section
         310 of the Trust Indenture Act after written request therefor by the
         Certificate Issuer or by any Holder of Certificates who has been a bona
         fide Holder of Certificates for at least six months; or

                  (ii) the Certificate Trustee shall cease to be eligible under
         Section 6.07 and shall fail to resign after written request therefor by
         the Certificate Issuer or by any Certificateholder; or

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

then, in any case, (x) the Certificate Issuer may remove the Certificate Trustee
or (y) any Holder of Certificates who has been a bona fide Holder of
Certificates for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Certificate Trustee and the appointment of a successor Certificate
Trustee.

         (f) If a Responsible Officer of the Certificate Trustee shall have
received written notice of an Avoidable Tax that has been or is likely to be
asserted, the Certificate Trustee shall promptly notify the Certificate Issuer
and the Note Issuer thereof and shall, within 30 days of such notification,
resign hereunder unless within such 30-day period the Certificate Trustee shall
have received notice that either the Certificate Issuer or the Note Issuer has
agreed to pay such tax. In such event, the Certificate Issuer (with the prior
written approval of the Note Issuer) shall promptly appoint a successor
Certificate Trustee in a jurisdiction where there are no Avoidable Taxes. As
used herein, an "Avoidable Tax" means a state or local tax: (i) upon (w) the
Certificate Issuer, (x) the Trust Property, (y) the Certificateholders or (z)
the Certificate Trustee for which the Certificate Trustee is entitled to seek
reimbursement from the Trust Property, and (ii) that would be avoided if the
Certificate Trustee were located in another state, or jurisdiction within a
state, within the United States. A tax shall not be an Avoidable Tax if either
the Certificate Issuer or the Note Issuer shall agree to pay, and shall pay,
such tax.

         (g) If the Certificate Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the
Certificate Trustee for any reason, the Certificate Issuer (with the prior
written approval of the Note Issuer and the Agencies) shall promptly appoint a
successor Certificate Trustee. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor
Certificate Trustee shall be appointed by Act of the Certificateholders
representing not less than a majority of the Outstanding Amount of the
Certificates delivered to the Certificate Issuer, the Note Trustee and the
retiring Certificate Trustee, the successor Certificate Trustee so appointed
shall, forthwith upon its acceptance of such appointment, become the successor
Certificate Trustee and supersede the successor Certificate Trustee appointed as
provided above. If no successor Certificate Trustee shall have been so appointed
as provided above and accepted appointment in the manner hereinafter

                                       37
<PAGE>   42
provided, any Holder of Certificates who has been a bona fide Holder of
Certificates for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Certificate Trustee.

         (h) The successor Certificate Trustee shall give notice of the
resignation and removal of the Certificate Trustee and appointment of the
successor Certificate Trustee by mailing written notice of such event by
first-class mail, postage prepaid, to the Holders as their names and addresses
appear in the Certificate Register and to each Rating Agency, the Certificate
Issuer and the Agencies. Each notice shall include the name of such successor
Certificate Trustee and the address of the corporate trust office of such
successor Certificate Trustee.

         (i) The Certificate Issuer shall notify the Rating Agencies and the
Agencies of any resignation and removal of the Certificate Trustee and
appointment of a successor Certificate Trustee under this Section 6.08.

         Section 6.09. Acceptance of Appointment by Successor. Every successor
Certificate Trustee appointed hereunder shall execute, acknowledge and deliver
to the Certificate Issuer and to the retiring Certificate Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Certificate Trustee shall become effective and such successor
Certificate Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring
Certificate Trustee; but, on request of the Certificate Issuer or the successor
Certificate Trustee, such retiring Certificate Trustee shall execute and deliver
an instrument transferring to such successor Certificate Trustee all the rights,
powers and trusts of the retiring Certificate Trustee and shall duly assign,
transfer and deliver to such successor Certificate Trustee all property and
money held by such retiring Certificate Trustee hereunder. Upon request of any
such successor Certificate Trustee, the Certificate Issuer, the retiring
Certificate Trustee and such successor Certificate Trustee shall execute and
deliver any and all instruments containing such provisions as shall be necessary
or desirable to transfer and confirm to, and for more fully and certainly
vesting in, such successor Certificate Trustee all such rights, powers and
trusts. No Certificate Trustee hereunder shall be liable for the acts or
omissions of any successor Certificate Trustee.

         No successor Certificate Trustee shall accept its appointment unless at
the time of such acceptance such successor Certificate Trustee shall be
qualified and eligible under this Article and any and all amounts due and
payable to the predecessor Certificate Trustee have been paid.

         Section 6.10. Merger, Conversion, Consolidation or Succession to
Business. Any corporation into which the Certificate Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Certificate Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Certificate Trustee, shall be the successor
of the Certificate Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.
In case any Certificates shall have been authenticated, but not delivered, by
the Certificate Trustee then in office, any successor by merger, conversion or
consolidation to such

                                       38
<PAGE>   43
authenticating Certificate Trustee may adopt such authentication and deliver the
Certificates so authenticated with the same effect as if such successor
Certificate Trustee had itself authenticated such Certificates.

         Section 6.11. Maintenance of Agencies.

         (a) There shall at all times be maintained in the Borough of Manhattan,
The City of New York, an office or agency where Certificates may be presented or
surrendered for registration of transfer or for exchange, and for payment
thereof and where notices and demands to or upon the Certificate Trustee on
behalf of the Certificate Issuer in respect of the Certificates or of this
Certificate Indenture may be served. At no time shall there be any other such
office or agency outside the United States. Such office or agency shall be
initially at The Bank of New York, 101 Barclay Street, Floor 12 East, New York,
New York 10286, Attention: Asset-Backed Finance Unit. Written notice of any
change of location thereof shall be given by the Certificate Trustee to the
Certificate Issuer, the Note Trustee, the Note Issuer, the Certificateholders,
the Agencies and the Rating Agencies. In the event that no such office or agency
shall be maintained or no such notice of location or of change of location shall
be given, presentations and demands may be made and notices may be served at the
Corporate Trust Office of the Certificate Trustee.

         (b) There shall at all times be a Certificate Registrar, an
Authentication Agent and a Paying Agent hereunder. Each such Authorized Agent
shall be a bank or trust company, shall be a entity organized and doing business
under the laws of the United States or any state, with a combined capital and
surplus of at least $50,000,000, shall have a long-term debt rating of at least
A by Moody's and by Standard & Poor's, shall be authorized under such laws to
exercise corporate trust powers and shall be subject to supervision by federal
or state authorities. The Certificate Trustee shall initially be the Paying
Agent, Authentication Agent, and, as provided in Section 2.06, Certificate
Registrar hereunder. Each Certificate Registrar, if other than the Certificate
Trustee, shall furnish to the Certificate Trustee, at stated intervals of not
more than six months, and at such other times as the Certificate Trustee may
request in writing, a copy of the Certificate Register.

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

         (d) Any Authorized Agent may at any time resign by giving written
notice of resignation to the Certificate Trustee, the Certificate Issuer and the
Note Trustee. The Certificate Issuer (with the prior written approval of the
Note Issuer) may, and at the request of the Certificate Trustee shall, at any
time terminate the agency of any Authorized Agent by giving written notice of
termination to such Authorized Agent, the Note Trustee and to the Certificate
Trustee. Upon

                                       39
<PAGE>   44
the resignation or termination of an Authorized Agent or in case at any time any
such Authorized Agent shall cease to be eligible under this Section (when, in
either case, no other Authorized Agent performing the functions of such
Authorized Agent shall have been appointed by the Certificate Trustee), the
Certificate Issuer (with the prior written approval of the Note Issuer) shall
promptly appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Certificate Trustee, to perform the functions of the
Authorized Agent who has resigned or whose agency has been terminated or who
shall have ceased to be eligible under this Section. The Certificate Issuer
shall give written notice of any such appointment made by it to the Certificate
Trustee and the Note Trustee; and in each case the Certificate Trustee shall
mail notice of such appointment to all Certificateholders as their names and
addresses appear on the Certificate Register.

         (e) Pursuant to the Fee and Indemnity Agreement, the Note Issuer has
agreed to pay, or cause to be paid, from time to time to each Authorized Agent
reasonable compensation for its services and to reimburse it for its reasonable
expenses; provided, however, that the Note Issuer shall have given prior consent
to the appointment of such Authorized Agent pursuant to the Fee and Indemnity
Agreement, and no Authorized Agent shall have any recourse against the
Certificate Issuer or the Trust Property for payment of such amounts.

         Section 6.12. Money for Certificate Payments To Be Held in Trust.

         (a) All moneys deposited with any Paying Agent for the purpose of any
payment on Certificates of any Class shall be deposited and held in trust for
the benefit of the Certificateholders of such Class entitled to such payment,
subject to the provisions of this Section. Moneys so deposited and held in trust
shall constitute a separate trust fund for the benefit of the Class of
Certificateholders with respect to which such money was deposited.

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

         (b) The Certificate Trustee will cause each Paying Agent other than the
Certificate Trustee to execute and deliver to the Certificate Trustee an
instrument in which such Paying Agent shall agree with the Certificate Trustee
(and, if the Certificate Trustee acts as Paying Agent, it hereby so agrees),
subject to the provisions of this Section, that such Paying Agent will:

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

                  (ii) give the Certificate Trustee notice of any default under
         this Certificate Indenture of which it has actual knowledge in the
         making of any payment required to be

                                       40
<PAGE>   45
         made by the Certificate Issuer (or any other obligor on the
         Certificates) with respect to the Certificates;

                  (iii) at any time during the continuance of such default, upon
         the written request of the Certificate Trustee, forthwith pay to the
         Certificate Trustee all sums held by it in trust for the payment of the
         Certificates if at any time it ceases to meet the standards required to
         be met by a Paying Agent at the time of its appointment; and

                  (iv) comply with all requirements of the Code with respect to
         the withholding from any payments made by it on any Certificates of any
         applicable withholding taxes imposed thereon and with respect to any
         applicable reporting requirements in connection therewith.

         Section 6.13. Registration of Notes in Certificate Trustee's Name. The
Certificate Trustee agrees that all Notes and Eligible Investments, if any,
shall be issued in the name of the Certificate Trustee or its nominee, on behalf
of the Certificate Issuer, and held by the Certificate Trustee, or, if not so
held, the Certificate Trustee or its nominee, on behalf of the Certificate
Issuer, shall be reflected as the owner of such Notes or Eligible Investments,
as the case may be, in the register of the issuer of such Notes or Eligible
Investments. In no event shall the Certificate Trustee invest in, or hold, Notes
or Eligible Investments in a manner that would cause the Certificate Trustee not
to have the ownership interest in such Notes or Eligible Investments under the
applicable provisions of the Uniform Commercial Code in effect in the location
where the Certificate Trustee holds such Notes or Eligible Investments or other
applicable law then in effect.

         Section 6.14. Representations and Warranties of Certificate Trustee.
The Certificate Trustee hereby represents and warrants that:

                  (a) the Certificate Trustee is validly existing as a state
         banking institution in good standing under the laws of the State of New
         York;

                  (b) the Certificate Trustee has full power, authority and
         legal right to execute, deliver and perform this Certificate Indenture
         and the Basic Documents to which the Certificate Trustee is a party and
         has taken all necessary action to authorize the execution, delivery,
         and performance by it of this Certificate Indenture and such Basic
         Documents; and

                  (c) when delivered by the Certificate Trustee, the
         Certificates will have been duly executed by the Delaware Trustee on
         behalf of the Certificate Issuer and duly authenticated by the
         Certificate Trustee.

         Section 6.15. Withholding Taxes; Information Reporting. The Certificate
Trustee, as trustee for the assets of a grantor trust, shall exclude and
withhold from each distribution of principal and interest and other amounts due
hereunder or under the Certificates any and all withholding taxes applicable
thereto as required by law. The Certificate Trustee agrees that it will act as
such withholding agent and, in connection therewith, whenever any present or
future taxes or similar

                                       41
<PAGE>   46
charges are required to be withheld with respect to any amounts payable in
respect of the Certificates, to withhold such amounts and timely pay the same to
the appropriate authority in the name of and on behalf of the
Certificateholders, that it will file any necessary withholding tax returns or
statements when due, and that, as promptly as possible after the payment
thereof, it will deliver to each Certificateholder appropriate documentation
showing the payment thereof, together with such additional documentary evidence
as such Certificateholders may reasonably request from time to time. The
Certificate Trustee agrees to file any other information reports as it may be
required to file with respect to taxes. For purposes of reporting on Internal
Revenue Service Form 1041 (and any statement attached thereto) or any successor
form thereto, the Certificate Trustee will separately set forth information
reported with respect to each Class of Certificates.

         Section 6.16. Obligations to Note Trustee and Delaware Trustee. It is
agreed by the parties hereto that the services of the Note Trustee and the
Delaware Trustee are an essential part of the transactions contemplated hereby.
Therefore, to the extent amounts payable under the Fee and Indemnity Agreement
to the Note Trustee and/or the Delaware Trustee are not paid when due, the
payment of such amounts shall be made by the Certificate Trustee and any amounts
so paid or to be paid by the Certificate Trustee shall constitute expenses of
the Certificate Trustee for which it is entitled to reimbursement under Section
6.06 of this Certificate Indenture and under Section 1(a) of the Fee and
Indemnity Agreement. Notwithstanding the foregoing, the Delaware Trustee and the
Note Trustee shall not have recourse against the Certificate Trustee with
respect to such amounts except to the extent the Certificate Trustee is
reimbursed under the Fee and Indemnity Agreement or realizes against the
Collateral under the Note Indenture or pursuant to any lien created by the
Statute or the Financing Order with respect to such amounts.

                                  ARTICLE VII

                       SUPPLEMENTAL CERTIFICATE INDENTURES

                  (b) to correct or supplement any provision herein or in any
         supplemental certificate indenture that may be defective or
         inconsistent with any other provision herein or in any supplemental
         certificate indenture or to make any other provisions with respect to
         matters or questions arising under this Certificate Indenture;
         provided, however, that any such action shall not adversely affect in
         any material respect the interests of the Certificateholders;

                  (d) to qualify, if necessary, this Certificate Indenture
         (including any supplemental certificate indenture) under the Trust
         Indenture Act, or under any similar federal statute hereafter enacted,
         and to add to this Certificate Indenture such other provisions as may
         be expressly permitted by the Trust Indenture Act, excluding, however,
         the provisions referred to in Section 316(a)(2) of the Trust Indenture
         Act as in effect at the date as of which this instrument was executed
         or any corresponding provision in any similar federal statute hereafter
         enacted.

         Section 7.02. Supplemental Certificate Indentures With Consent of
Certificateholders. With the consent of the Certificateholders holding
Certificates representing not less than a majority of the aggregate Outstanding
Amount of Certificates of each Class affected thereby, by Act of said
Certificateholders delivered to the Certificate Issuer, the Note Trustee and the
Certificate Trustee, the Certificate Issuer (with the prior written approval of
the Note Issuer) may, and the Certificate Trustee (subject to Section 7.03)

of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Certificate Indenture or of modifying in any manner the

this Certificate Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Certificateholder of each
Outstanding Certificate affected thereby:

                  (a) reduce in any manner the amount of, or delay the timing
         of, any receipt by the Certificate Trustee of payments on the Notes or

         any Holder of Certificates of any Class of the benefit of the ownership
         of the Notes of the corresponding Class in the Trust;

                  (c) reduce the percentage of the aggregate Outstanding Amount
         of the Certificates of any Class that is required for any such
         supplemental indenture, or reduce such percentage required for any
         waiver or consent (of compliance with certain provisions of this
         Certificate Indenture or certain defaults hereunder and their
         consequences) provided for in this Certificate Indenture;

                  (d) modify any of the provisions of this Section, except to
         increase any percentage set forth herein or to provide that certain
         other provisions of this Certificate Indenture cannot be modified or
         waived without the consent of the Holder of each Certificate affected
         thereby; or

                                       43
<PAGE>   48
                  (e) adversely affect the status of the Trust as a grantor
         trust for federal income tax purposes.

         It shall not be necessary for any Act of Certificateholders under this
Section to approve the particular form of any proposed supplemental certificate
indenture, but it shall be sufficient if such Act shall approve the substance
thereof. The Certificate Issuer shall give each Rating Agency five Business Days
prior written notice of any such proposed supplemental certificate indenture.
Promptly after the execution by the Certificate Issuer and the Certificate
Trustee of any supplemental certificate indenture pursuant to this Section, the
Certificate Trustee shall mail to the Holders of the Certificates to which such
supplemental certificate indenture relates a notice setting forth in general
terms the substance of such supplemental certificate indenture. Any failure of
the Certificate Trustee to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental
certificate indenture.

         Section 7.03. Documents Affecting Immunity or Indemnity. If in the
opinion of the Certificate Trustee any document required to be executed by it
pursuant to the terms of Section 7.01 or 7.02 adversely affects any interest,
right, duty, immunity or indemnity in favor of the Certificate Trustee under
this Certificate Indenture, the Certificate Trustee may in its discretion
decline to execute such document.

         Section 7.04. Execution of Supplemental Certificate Indentures. In
executing, or accepting the additional trusts created by, any supplemental
certificate indenture permitted by this Article or the modifications thereby of
the trusts created by this Certificate Indenture, the Certificate Trustee shall
be entitled to receive, and shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such supplemental certificate indenture
is authorized or permitted by this Certificate Indenture.

         Section 7.05. Effect of Supplemental Certificate Indentures. Upon the
execution of any supplemental certificate indenture under this Article, this
Certificate Indenture shall be modified in accordance therewith, and such
supplemental certificate indenture shall form a part of this Certificate
Indenture for all purposes; and every Holder of any Certificate theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

         Section 7.06. Conformity with Trust Indenture Act. Every supplemental
certificate indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act as then in effect.

         Section 7.07. Reference in Certificates to Supplemental Certificate
Indentures. Certificates authenticated and delivered after the execution of any
supplemental certificate indenture pursuant to this Article may bear a notation
in form approved by the Certificate Trustee as to any matter provided for in
such supplemental certificate indenture; and, in such case, suitable notation
may be made upon Outstanding Certificates after proper presentation and demand.

                                  ARTICLE VIII

               AMENDMENTS AND SUPPLEMENTS TO NOTES, NOTE INDENTURE
                            AND OTHER BASIC DOCUMENTS

         Section 8.01. Amendments and Supplements to Notes, Note Indenture and
Other Basic Documents. In the event that the Certificate Issuer or the
Certificate Trustee, as holder of the Notes of each Class in trust for the
benefit of the Holders of Certificates of the corresponding Class, receives a
request for a consent to any amendment, modification, waiver or supplement under
the Notes, the Note Indenture or any other Basic Document to which the
Certificate Issuer or the Certificate Trustee is a party, the Certificate Issuer
shall forward such request for consent to the Certificate Trustee, and the
Certificate Trustee shall forthwith send a notice of such proposed amendment,
modification, waiver or supplement, to each Holder of Certificates of such Class
registered on the Certificate Register as of such date. The Certificate Trustee
shall request from such Certificateholders directions as to (a) whether or not
the Certificate Trustee should take or refrain from taking any action that a
holder of such Note has the option to direct, (b) whether or not to give or
execute or direct the Certificate Issuer to give or execute any waivers,
consents, amendments, modifications or supplements as a holder of such Note and
(c) how to vote such Note if a vote has been called for with respect thereto;
provided, however, in the case of any change to the terms of, or modification
to, the Notes, the Certificateholders may not direct any such action to be taken
or direct whether or not to give or execute any such waiver, consent, amendment,
modification or supplement that is not pursuant to the original terms of the
Notes, unless the Certificate Trustee obtains an Opinion of Counsel at the
expense of the Certificate Issuer of independent tax counsel to the effect that
after any such action, waiver, consent, amendment, modification or supplement
the Trust will continue to be treated as a "grantor trust" for federal income
tax purposes. Provided such a request for Certificateholder direction shall have
been made, in directing any action or casting any vote or giving any consent as
the holder of the Notes, the Certificate Trustee shall vote or consent with
respect to such Notes in the same proportion as the Certificates of the
corresponding Class were actually voted by Acts of the Holders thereof delivered
to the Certificate Trustee prior to two Business Days before the Certificate
Trustee takes such action or casts such vote or gives such consent.

                                   ARTICLE IX

                           SATISFACTION AND DISCHARGE

         Section 9.01. Satisfaction and Discharge of Certificate Indenture. This
Certificate Indenture shall cease to be of further effect with respect to the
Certificates, and the Certificate Trustee, on reasonable demand of and at the
expense of the Certificate Issuer, shall execute proper instruments
acknowledging satisfaction and discharge of this Certificate Indenture with
respect to the Certificates, upon the distribution to all Holders of
Certificates and the Certificate Trustee of all amounts required to be
distributed to them pursuant to this Certificate Indenture and the disposition
of all property held as part of the Trust Property. The Certificate Issuer shall
pay or provide for the payment of all remaining liabilities of the Certificate
Trustee, but solely from amounts payable by the Note Issuer under the Fee and
Indemnity Agreement.

                                       45
<PAGE>   50
         Notice of any distribution pursuant to the paragraph above shall be
mailed promptly by the Certificate Trustee to Holders of Certificates then
outstanding. Such notice shall specify the Distribution Date or Special
Distribution Date, as the case may be, upon which the Holders of Certificates
may surrender their Certificates to the Certificate Trustee for payment of the
final distribution and cancellation. Such notice shall be mailed (a) if with
respect to a final distribution, as soon as practicable following receipt of
notice from the Note Trustee of a final payment on a corresponding Note, (b) if
with respect to a Special Payment other than a Special Payment constituting a
redemption, not earlier than the 60th day and not later than the 20th day next
preceding such final distribution or (c) if with respect to a Special Payment
constituting a redemption of Certificates resulting from a redemption of Notes,
then in accordance with the provisions of the relevant Section of Article IV
hereof. Such notice shall specify (a) the Distribution Date or Special
Distribution Date, as the case may be, upon which the proposed final payment of
the Certificates will be made upon presentation and surrender of such
Certificates at the office or agency of the Certificate Trustee therein
specified, (b) the amount of any such proposed final payment and (c) that the
Record Date otherwise applicable to such Distribution Date or the Special Record
Date otherwise applicable to such Special Distribution Date, as the case may be,
is not applicable, payments being made only upon presentation and surrender of
the Certificates at the office or agency of the Certificate Trustee therein
specified. The Certificate Trustee shall give such notice to the Certificate
Registrar at the time such notice is given to Holders of Certificates. Upon
presentation and surrender of such Certificates, the Certificate Trustee shall
cause to be distributed to the Holders thereof amounts distributable thereon on
such Distribution Date or Special Distribution Date, as the case may be,
pursuant to Section 4.02.

         In the event that all of the Holders of Certificates shall not
surrender their Certificates for cancellation within six months after the date
specified in the above mentioned written notice, the Certificate Trustee shall
give a second written notice to the remaining Holders of such Certificates to
surrender their Certificates for cancellation and receive the final distribution
with respect thereto. In the event that any money held by the Certificate
Trustee for the payment of distributions on the Certificates shall remain
unclaimed for two years (or such lesser time as the Certificate Trustee shall be
satisfied, after 60 days' notice from the Certificate Issuer (with the prior
written approval of the Note Issuer), is one month prior to the escheat period
provided under applicable law) after the final distribution date with respect
thereto, the Certificate Trustee shall pay such money to the Note Trustee for
deposit into the collection account relating to the related Notes or, if such
collection account no longer exists, to the Note Issuer and the Certificate
Trustee or Note Issuer shall give written notice thereof to the Note Trustee,
the Note Issuer and the Certificate Issuer.

                            MISCELLANEOUS PROVISIONS

         Section 10.1. Commonwealth Pledge; Certificates and Notes Not
Obligation of The Commonwealth of Massachusetts, Agencies or Seller.

                                       46
<PAGE>   51
         (a) The Certificate Issuer hereby finds and determines, and hereby
represents and warrants, that it constitutes a "special purpose trust" and a
"financing entity" under Section 1H(a) of the Statute, and that the Certificates
constitute "electric rate reduction bonds" under Section 1H(a) of the Statute
and that the Holders of the Certificates are entitled to the rights and benefits
thereunder. Pursuant to Section 1H(b)(3) of the Statute, The Commonwealth of
Massachusetts pledges and agrees with the Note Issuer, the Certificate Issuer
and the Holders of the Certificates (the "Commonwealth Pledge") as follows:

                  (b) [T]he [C]ommonwealth [of Massachusetts] does hereby pledge
                  and agree with the owners of the transition property and
                  holders of electric rate reduction bonds that the
                  [C]ommonwealth [of Massachusetts] shall not (i) alter the
                  provisions of this chapter which make the transition charges
                  imposed by the financing order irrevocable and binding or (ii)
                  limit or alter the reimbursable transition costs amounts,
                  transition property, financing orders, and all rights
                  thereunder until the electric rate reduction bonds, together
                  with the interest thereon, are fully met and discharged.

         (c) Further, the Certificate Issuer does hereby pledge and agree with
the Note Issuer and the Holders of the Certificates that it will not act in a
manner inconsistent with the Commonwealth Pledge and will not take any action
that would impair any rights of the Note Issuer or the Holders of the
Certificates or the Notes, the Transition Property or the Certificates. The
Certificate Issuer hereby further agrees to treat the Notes as debt of the Note
Issuer, secured by, among other things, the Transition Property and the equity
of the Note Issuer on deposit in the Capital Subaccount, for all purposes.

         (d) Each Certificate represents a fractional undivided beneficial
interest in a corresponding Class of Notes and the proceeds thereof. The
Certificates and the Notes do not represent an interest in or obligation of The
Commonwealth of Massachusetts, the Agencies, any other governmental agency or
instrumentality or the Seller or any of its affiliates, except for BEC Funding
LLC, which is an affiliate of Boston Edison. None of the Certificates, the Notes
or the underlying Transition Property will be guaranteed or insured by The
Commonwealth of Massachusetts, the Agencies, the Certificate Issuer or any other
governmental agency or instrumentality or by the Seller or its affiliates.

         Neither the full faith and credit nor the taxing power of The
Commonwealth of Massachusetts, the Agencies or any other governmental agency or
instrumentality is pledged to the payment of the principal of, purchase price
of, or interest on, the Certificates or the Notes, or to the payments in respect
of the Transition Property, nor are The Commonwealth of Massachusetts, the
Agencies or any other governmental agency or instrumentality in any manner
obligated to make any appropriation for the payment thereof.

         Section 10.2. Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder shall not operate to terminate this
Certificate Indenture, the Declaration of Trust or the Certificate Issuer, nor
entitle such Certificateholder's legal representatives or heirs to claim an
accounting or to take any action or commence any proceeding in any court for a
partition or

                                       47
<PAGE>   52
winding up of the Certificate Issuer, nor otherwise affect the rights,
obligations, and liabilities of the parties hereto or any of them.

         Section 10.03. No Recourse to Certificate Issuer. Notwithstanding any
provision of this Certificate Indenture or any supplemental certificate
indenture to the contrary, Holders shall have no recourse against the
Certificate Issuer or the Agencies, but shall look only to the Trust Property
with respect to any amounts due to the Holders hereunder and under the
Certificates.

         Section 10.04. Certificates Nonassessable and Fully Paid. Pursuant to
Section 3803(a) of the Business Trust Statute, Certificateholders shall be
entitled to the same limitation of personal liability extended to stockholders
of private corporations for profit organized under the General Corporation law
of the State of Delaware. Certificateholders shall not be personally liable for
obligations of the Certificate Issuer, the interests in the Certificate Issuer
represented by the Certificates shall be nonassessable for any losses or
expenses of the Certificate Issuer or for any reason whatsoever, and upon
authentication of the Certificates by the Certificate Trustee pursuant to
Section 2.04, the Certificates are and shall be deemed fully paid and
non-assessable. No Certificateholder shall have any right (except as expressly
provided herein) to vote or in any manner otherwise control the operation and
management of the Trust Property, the Certificate Issuer, or the obligations of
the parties hereto, nor shall anything set forth herein, or contained in the
terms of the Certificates, be construed so as to constitute the
Certificateholders from time to time as partners or members of an association.

         Section 10.05. Notices.

         (a) Unless otherwise specifically provided herein, all notices,
directions, consents and waivers required under the terms and provisions of this
Certificate Indenture shall be in English and in writing, and any such notice,
direction, consent or waiver may be given by United States mail, courier
service, facsimile transmission or electronic mail (confirmed by telephone,
United States mail or courier service in the case of notice by facsimile
transmission or electronic mail) or any other customary means of communication,
and any such notice, direction, consent or waiver shall be effective when
delivered, or if mailed, three days after deposit in the United States mail with
proper postage for ordinary mail prepaid,

         THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE
         TRUST OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT,
         AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR
         IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
         DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS
         IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER,
         PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
         IS WRONGFUL INASMUCH THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
         INTEREST HEREIN.

         This Certificate evidences a fractional undivided beneficial interest
in an Underlying Note (as defined below) of the corresponding class issued by
BEC Funding LLC, a Delaware limited liability company, and the proceeds thereof,
held by a trust or registered assigns, as more fully described herein.

         This Certificate does not represent an interest in or obligation of The
Commonwealth of Massachusetts, the Massachusetts Development Finance Agency or
the Massachusetts Health and Educational Facilities Authority (collectively, the
"Agencies"), any other governmental

                                      A-1
<PAGE>   59
agency or instrumentality or Boston Edison Company, a Massachusetts corporation
("Boston Edison"), or any of its affiliates. None of the Certificate, the
Underlying Note or the underlying Transition Property (as defined in the
Certificate Indenture) will be guaranteed or insured by The Commonwealth of
Massachusetts, either of the Agencies, the Trust (as defined below) or any other
governmental agency or instrumentality or by Boston Edison or its affiliates.

         Neither the full faith and credit nor the taxing power of The
Commonwealth of Massachusetts, either of the Agencies or any other governmental
agency or instrumentality is pledged to the payment of the principal of,
purchase price of, or interest on, this Certificate or the Underlying Note, or
to the payments in respect of the Transition Property, nor are The Commonwealth
of Massachusetts, either of the Agencies or any other governmental agency or
instrumentality in any manner obligated to make any appropriation for the
payment thereof.

         To the extent not otherwise defined herein, the capitalized terms used
herein have the meanings assigned to them in the Certificate Indenture.

         THIS CERTIFIES THAT CEDE & CO., as nominee for The Depository Trust
Company, for value received, is the registered owner of a Principal Amount
(stated above) of nonassessable, fully-paid, fractional undivided beneficial
interest in the related Underlying Note and the proceeds thereof held by
Massachusetts RRB Special Purpose Trust BEC-1 (the "Trust") or registered
assigns. The Trust is created pursuant to a Declaration of Trust dated as of
July 28, 1999 by The Bank of New York (Delaware), as Delaware Trustee (the
"Delaware Trustee"), and the Agencies, acting jointly as settlors thereunder
pursuant to Chapter 164 of the Massachusetts Acts of 1997 (the "Statute"). This
Certificate is issued under and is subject to the terms, provisions, and
conditions of, a Certificate Indenture dated as of July 29, 1999 (the
"Certificate Indenture"), by and among the Delaware Trustee, The Bank of New
York, as certificate trustee (the "Certificate Trustee"), and the Trust, a
summary of certain of the pertinent provisions of which is set forth below. This
Certificate is one of the duly authorized class of Certificates designated as
"Massachusetts RRB Special Purpose Trust BEC-1 Rate Reduction Certificates,
Class [ ]" (herein called the "Class [ ] Certificates"). The Class [ ]
Certificates are one of a class of Certificates issued under the Certificate
Indenture (such Class [ ] Certificates, together with other Classes of
Certificates issued on the date hereof under the Certificate Indenture being
herein called the "Certificates"). The holder of this Certificate (the
"Holder"), by virtue of its acceptance hereof, assents and agrees to be bound by
the terms of the Certificate Indenture. This Class [ ] Certificate represents a
fractional undivided beneficial interest in the note of the corresponding class
(the "Underlying Note") issued by BEC Funding LLC, as Note Issuer, together with
the payments on and proceeds of the Underlying Note. The Underlying Note is
secured by a security interest in the property right created under the Statute,
pursuant to the order of the Massachusetts Department of Telecommunications and
Energy, DTE-98-118, issued on April 2, 1999, as further clarified by the Order
on the Massachusetts Development Finance Agency's and the Massachusetts Health
and Educational Facilities Authority's Motion for Clarification dated May 21,
1999 (collectively, the "Financing Order"), representing the irrevocable right
of Boston Edison or its assignee to receive a certain

                                      A-2
<PAGE>   60
nonbypassable charge (as adjusted from time to time) from certain retail
customers of Boston Edison's distribution system, together with certain related
collateral, all as more fully described in the Note Indenture.

         The aggregate principal amount of all Certificates of all Classes
issued under the Certificate Indenture equals the aggregate principal amount of
the Underlying Notes of all Classes, and all such Certificates are and will be
equally secured by the pledge and covenants made therein, except as otherwise
expressly provided or permitted in the Certificate Indenture.

         Subject to and in accordance with the terms of the Certificate
Indenture, there will be distributed on each March 15 and September 15 of each
year or, if any such day is not a Business Day, the next succeeding Business Day
(each, a "Distribution Date"), commencing on March 15, 2000 to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day immediately preceding the related Distribution Date or, if
Definitive Certificates are issued, the last day of the immediately preceding
calendar month (each, a "Record Date"), such Holder's fractional undivided
interest in the payments made on the Underlying Note due on the related Payment
Date, the receipt of which has been confirmed by the Certificate Trustee.
Subject to and in accordance with the terms of the Certificate Indenture, in the
event that a Special Payment on the Underlying Note is received by the
Certificate Trustee, from funds then available to the Certificate Trustee, there
will be distributed on the applicable Special Distribution Date, to the Person
in whose name this Certificate is registered on the Record Date preceding the
Special Distribution Date, as applicable, such Holder's fractional undivided
share of such amount. The Special Distribution Date will be determined as
provided in the Certificate Indenture. The Certificate Trustee will mail notice
of each Special Payment and the related Special Distribution Date to the Holder
as provided in the Certificate Indenture.

         Distributions on this Certificate will be made as provided in the
Certificate Indenture by the Certificate Trustee by wire transfer or check
mailed to the Holder of record in the Certificate Register without the
presentation or surrender of this Certificate or the making of any notation
hereon, except that with respect to Certificates registered on the Record Date
in the name of the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Except as otherwise provided in
the Certificate Indenture and notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Certificate Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office of the Paying Agent or the office or agency
maintained for that purpose by the Certificate Trustee in The City of New York.

         (a) Subject to and in accordance with the terms of the Certificate
Indenture, the Trust has represented and warranted under the Certificate
Indenture that the Trust constitutes a "special purpose trust" and a "financing
entity" under Section 1H(a) of the Statute, and that the Certificates constitute
"electric rate reduction bonds" under Section 1H(a) of the Statute and that the
Holders are entitled to the rights and benefits thereunder. Pursuant to Section
1H(b)(3) of the

                                      A-3
<PAGE>   61
Statute, The Commonwealth of Massachusetts, has pledged and agreed with the Note
Issuer, the Trust and the Holders (the "Commonwealth Pledge") as follows:

                  (b) [T]he [C]ommonwealth [of Massachusetts] does hereby pledge
                  and agree with the owners of the transition property and
                  holders of electric rate reduction bonds that the
                  [C]ommonwealth [of Massachusetts] shall not (i) alter the
                  provisions of this chapter which make the transition charges
                  imposed by the financing order irrevocable and binding or (ii)
                  limit or alter the reimbursable transition costs amounts,
                  transition property, financing orders, and all rights
                  thereunder until the electric rate reduction bonds, together
                  with the interest thereon, are fully met and discharged.

         In addition, the Trust has pledged and agreed with the Note Issuer and
the Holders that it will not act in a manner inconsistent with the Commonwealth
Pledge and will not take any action that would impair any rights of the Note
Issuer or the Holders in the Notes, the Transition Property or the Certificates.

         Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon shall have been
executed by an authorized officer of the Certificate Trustee by manual
signature, this Certificate shall not be entitled to any benefit under the
Certificate Indenture or any other Basic Document or be valid for any purpose.

         THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE DOMESTIC LAW OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF
LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES
HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAW.

         Any reduction in the principal amount of any Certificate effected by
any distribution in respect of principal thereof shall be binding upon all
Holders of such Certificate and of any Certificate issued upon the registration
of transfer thereof or in exchange thereof or in lieu thereof, whether or not
noted thereon.

                  It is expressly agreed and understood by the parties hereto
that (a) this Certificate is executed by The Bank of New York (Delaware) and
authenticated and delivered by The Bank of New York, not individually or
personally but solely as Delaware Trustee and Certificate Trustee, respectively,
on behalf of the Trust in the exercise of the powers and authority conferred and
vested in them, (b) the representations, undertakings and agreements herein made
by the Delaware Trustee and Certificate Trustee on behalf of the Trust are made
and intended not as

                                      A-4
<PAGE>   62
personal representations, undertakings and agreements of either trustee, but are
made and intended for the purpose of binding only the Trust, (c) nothing herein
contained shall be construed as creating any liability on The Bank of New York
(Delaware) or The Bank of New York, individually or personally, to perform any
covenant either expressed or implied herein, except in their capacity as
Delaware Trustee and Certificate Trustee, respectively, all such liability being
expressly waived by all Persons, and (d) under no circumstances shall The Bank
of New York (Delaware) or The Bank of New York be personally liable for the
payment of any indebtedness or expenses of the Trust, or be personally liable
for the breach or failure of any obligation, representation, warranty or
covenant made or undertaken by the Trust under the Certificate Indenture.

<PAGE>   65
                        [FORM OF REVERSE OF CERTIFICATE]

                  The Certificates are limited in right of payment, all as more
specifically set forth on the face hereof and in the Certificate Indenture. All
payments or distributions made to Holders under the Certificate Indenture shall
be made only from the Trust Property and only to the extent that the Certificate
Trustee shall have sufficient income or proceeds from the Trust Property to make
such payments in accordance with the terms of the Certificate Indenture. Each
Holder, by its acceptance hereof, agrees that it will look solely to the income
and proceeds from the Trust Property to the extent available for distribution to
such Holder as provided in the Certificate Indenture. This Certificate does not
purport to summarize the Certificate Indenture and reference is made to the
Certificate Indenture for information with respect to the interests, rights,
benefits, obligations, proceeds, and duties evidenced hereby. A copy of the
Certificate Indenture may be examined during normal business hours at the
principal office of the Certificate Trustee, and at such other places, if any,
designated by the Certificate Trustee, by any Holder upon request.

                  The Certificate Indenture permits, with certain exceptions
therein provided, the amendment thereof and the modification of the rights of
the Holders under the Certificate Indenture at any time by the Trust and the
Certificate Trustee with the consent of the Holders holding Certificates
representing not less than a majority of the aggregate Outstanding Amount of
Certificates of each affected Class issued by the Trust. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Certificate
Indenture also permits the amendment thereof, in certain limited circumstances,
without the consent of the Holders of any of the Certificates.

                  As provided in the Certificate Indenture and subject to
certain limitations therein set forth, the transfer of this Certificate is
registerable in the Certificate Register upon surrender of this Certificate for
registration of transfer at the offices or agencies maintained by the
Certificate Trustee in its capacity as Certificate Registrar, or by any
successor Certificate Registrar, in the Borough of Manhattan, The City of New
York, duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Certificate Trustee and the Certificate Registrar duly
executed by the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of authorized denominations
evidencing the same aggregate fractional undivided beneficial interest in the
Underlying Note will be issued to the designated transferee or transferees.

                  The Certificates are issuable only as registered Certificates
without coupons in Minimum Denominations of $1,000 Original Principal Amount and
integral multiples thereof. As provided in the Certificate Indenture and subject
to certain limitations therein set forth, Certificates are exchangeable for new
Certificates of authorized denominations evidencing the

                                      A-8
<PAGE>   66
same aggregate fractional undivided beneficial interest in the Underlying Notes,
as requested by the Holder surrendering the same.

         THE HOLDER, BY PURCHASE OF THIS CERTIFICATE, WILL BE DEEMED TO
REPRESENT THAT SUCH PURCHASE WILL NOT RESULT IN A NON-EXEMPT PROHIBITED
TRANSACTION UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED, OR THE EMPLOYEE
RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED, AND, IN EACH CASE, THE RULES
AND REGULATIONS THEREUNDER.

                  No service charge will be made for any such registration of
transfer or exchange, but the Certificate Trustee shall require payment of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

                  The Certificate Trustee, the Certificate Registrar, and any
agent of the Certificate Trustee or the Certificate Registrar may treat the
person in whose name this Certificate is registered as the owner hereof for all
purposes, and neither the Certificate Trustee, the Certificate Registrar, nor
any such agent shall be affected by any notice to the contrary.

                  The obligations and responsibilities created by the
Certificate Indenture shall terminate with respect to the Certificates upon the
distribution to the Holders of all amounts required to be distributed to them
pursuant to the Certificate Indenture and the disposition of all property held
as part of the Trust Property, except certain indemnity obligations of the Note
Issuer to the Certificate Trustee under the Fee and Indemnity Agreement.

<PAGE>   4
         DECLARATION OF TRUST dated as of July 28, 1999 (as amended or restated
from time to time, the "Declaration"), by the Massachusetts Development Finance
Agency and the Massachusetts Health and Educational Facilities Authority, acting
jointly hereunder as settlors pursuant to Chapter 164 of the Massachusetts Acts
of 1997 (the "Statute") (each an "Agency," and, collectively, the "Agencies")
and The Bank of New York (Delaware), a Delaware banking corporation, acting
hereunder not in its individual or corporate capacity but solely as trustee
under the laws of the State of Delaware (the "Delaware Trustee").

                                    RECITALS

         Pursuant to the Statute, an electric company in The Commonwealth of
Massachusetts may obtain from the Massachusetts Department of Telecommunications
and Energy (the "DTE") a financing order (as defined in the Statute) permitting
such utility to recover a portion of its transition costs (as defined in the
Statute) through the issuance of electric rate reduction bonds (as defined in
the Statute). The Statute further empowers a special purpose trust (as defined
in the Statute) established by the Agencies to issue such electric rate
reduction bonds.

         Boston Edison Company, a Massachusetts corporation ("Boston Edison"),
has applied for and received a financing order from the DTE, and has requested
the Agencies to establish a special purpose trust to issue electric rate
reduction bonds.

         The Trust created hereby (the "Trust") shall constitute a special
purpose trust and shall be empowered to issue one series with one or more
classes of certificates constituting Massachusetts RRB Special Purpose Trust
BEC-1 Rate Reduction Certificates (the "Certificates"). All such Certificates
shall be issued pursuant to an indenture (the "Certificate Indenture"), by and
among the Delaware Trustee, the Trust and a trustee (the "Certificate Trustee"),
initially designated as The Bank of New York, and each class of Certificates
shall represent fractional undivided beneficial interests in the corresponding
class of BEC Funding LLC Notes (the "Notes") issued by BEC Funding LLC, a
special purpose limited liability company (the "Note Issuer") created by Boston
Edison. The Certificate Indenture and this Declaration shall together constitute
the governing instrument of the Trust. The Trust shall purchase the Notes from
the Note Issuer pursuant to a note purchase agreement (a "Note Purchase
Agreement") relating to the Notes. The Notes will be issued pursuant to an
indenture (the "Note Indenture"), by and between the Note Issuer and a trustee
(the "Note Trustee"), initially designated as The Bank of New York, and secured
by a pledge of and lien upon transition property (as defined in the Statute)
purchased by the Note Issuer from Boston Edison together with any other assets
of the Note Issuer. Boston Edison will service such transition property for the
benefit of the Note Issuer pursuant to a transition property servicing agreement
(the "Servicing Agreement"), between Boston Edison as servicer (in such
capacity, together with any successor servicer, the "Servicer") and the Note
Issuer. The Declaration, the Certificate Indenture, the Note Purchase Agreement,
the Note Indenture, the Servicing Agreement, the Fee and Indemnity Agreement
defined and described in Section 2.7 hereof, the Transition Property Purchase
and Sale Agreement between the Note Issuer and Boston Edison, as seller,
relating to the purchase and sale of the transition property described above,
the Administration Agreement between the Note Issuer and Boston Edison, as
administrator, relating to the administration of the


                                       1
<PAGE>   5
Note Issuer, and the Underwriting Agreement among the Note Issuer, Boston Edison
and certain underwriters, relating to the underwriting of the Certificates, are
herein collectively referred to as the "Basic Documents."



THE AGENCIES AND THE DELAWARE TRUSTEE AGREE AS FOLLOWS:



                                   ARTICLE 1

                   DEFINITIONS AND INCORPORATION BY REFERENCE

         SECTION 1.1 Definitions. All references herein to "the Declaration" or
"this Declaration" are to this Declaration of Trust, all references herein to
the "Trust" are to the trust created hereunder, and all references herein to
Articles, Sections, subsections, Schedules and Exhibits are to Articles,
Sections, subsections, Schedules and Exhibits of this Declaration, unless
otherwise specified. All capitalized terms used herein and not otherwise defined
shall have the meanings set forth in the Recitals hereto.

                                   ARTICLE 2

                                  ORGANIZATION

         SECTION 2.1 Creation of Trust. The Trust created hereby shall be known
as "Massachusetts RRB Special Purpose Trust BEC-1," in which name the Delaware
Trustee may conduct the business of the Trust, make and execute contracts and
other instruments on behalf of the Trust and sue and be sued on behalf of the
Trust. In addition, the Delaware Trustee may conduct the business of the Trust
in its own name, as trustee hereunder, to the extent deemed necessary or
appropriate by the Delaware Trustee, in its sole discretion; provided that the
Delaware Trustee may rely conclusively upon an opinion of counsel as to whether
any proposed action is necessary or appropriate. It is the intention that the
Trust shall constitute a not-for-profit business trust under the Delaware
Business Trust Act (being Chapter 38 of Title 12 of the Delaware Code, 12 Del.
C., Section 3801 et seq., as the same may be amended from time to time and any
successor statute) (the "Business Trust Act"), that the Certificate Indenture
shall be deemed a part of this Declaration and that this Declaration (together
with the Certificate Indenture) shall constitute the governing instrument of the
Trust. To the extent that the provisions of this Declaration and the Certificate
Indenture conflict with respect to the issuance of the Certificates and the
rights of the holders thereof, the Certificate Indenture shall control. The
Delaware Trustee and the Certificate Trustee shall file the Certificate of
Trust, substantially in the form attached hereto as Exhibit A, pursuant to
Section 3810 et seq. of the Business Trust Act in connection with the formation
of the Trust as a not-for-profit business trust under the Business Trust Act.
The fiscal year of the Trust shall be the calendar year.

         SECTION 2.2 Trust as Financing Entity. The Agencies hereby find and
determine, and hereby represent and warrant, that the Trust constitutes a
"special purpose trust" and a "financing


                                       2
<PAGE>   6
entity" within the meaning of the Statute, and that the Trust is being
established to issue "electric rate reduction bonds" within the meaning of the
Statute.

         SECTION 2.3 Situs of the Trust. The office of the Trust shall be in
care of the Delaware Trustee at the corporate trust office (the "Office") at
White Clay Center, Route 273, Newark, Delaware 19711 (although any notice,
direction, consent or waiver given to the Delaware Trustee hereunder may be
given in care of the address set forth in Section 7.3(a) hereof), which Office
shall be located in Delaware, or at such other address in Delaware as the
Delaware Trustee may designate by written notice to the Agencies, the
Certificate Trustee, the Note Issuer, the Note Trustee, the Servicer, and the
holders of the Certificates, and the Trust shall conduct its business in such
Office, separate and apart from that of the Agencies and their affiliates. If
and to the extent required pursuant to the provisions of the Business Trust Act,
all bank accounts of the Trust maintained by the Delaware Trustee, except those
bank accounts maintained by the Certificate Trustee, shall be located in the
State of Delaware. Any bank accounts of the Trust maintained by the Delaware
Trustee that are not required to be located in the State of Delaware by the
Business Trust Act may be maintained in Delaware or New York, or such other
location as is acceptable to the Agencies. The Trust shall not have any
employees in any state other than Delaware; provided, however, that nothing
herein shall restrict or prohibit the Delaware Trustee (in its individual
capacity but not as Delaware Trustee) from having employees within or without
the State of Delaware. If and to the extent required pursuant to the provisions
of the Business Trust Act, payments shall be received by the Trust only in
Delaware, and payments shall be made by the Trust only from Delaware, except as
otherwise provided in the Basic Documents. To the extent the Business Trust Act
does not require that payments be received in and paid from Delaware, to the
extent consistent with such act and the Basic Documents, payments may be
received and made by the Trust in and from Delaware, New York or such other
location as is acceptable to the Agencies. To the extent required pursuant to
the provisions of the Business Trust Act, the Delaware Trustee shall conduct the
Trust's activities from Delaware, sign documents on behalf of the Trust in
Delaware and maintain business records on behalf of the Trust in Delaware.

         SECTION 2.4 Purposes and Powers.

         (a) The Trust is constituted solely for the purpose of acquiring and
holding the Notes and issuing the Certificates, applying the proceeds of the
Notes to the payment of the Certificates and entering into and performing its
obligations under each of the Basic Documents to which it may be a party (which
functions the Delaware Trustee shall perform or cause to be performed on behalf
of the Trust), and, except as set forth herein, the Delaware Trustee is not
authorized or empowered to acquire any other investments or engage in any other
activities on behalf of the Trust and, in particular, the Delaware Trustee is
not authorized or empowered to do anything that would cause the Trust to fail to
qualify as a "grantor trust" for federal income tax purposes.

         (b) The Delaware Trustee shall have all rights and powers set forth
herein and, to the extent not inconsistent herewith, in the Business Trust Act
with respect to accomplishing the purposes of the Trust.


                                       3
<PAGE>   7
         SECTION 2.5 Trust Property.

               (a) The Agencies hereby assign, transfer, convey and set over to
the Delaware Trustee on behalf of the Trust the sum of $1.00. The Delaware
Trustee hereby acknowledges receipt of such amount in trust from the Agencies,
which amount shall constitute the initial trust property.

               (b) Upon issuance of the Certificates and purchase of the Notes,
the holders of the Certificates shall become the sole and exclusive beneficial
owners of the Trust estate established hereby. The Delaware Trustee hereby
declares that it shall hold the Notes, the security interest in the transition
property (as defined in the Statute) securing the Notes, any other assets
acquired directly or indirectly from the Note Issuer and the proceeds therefrom
(the "Trust Property") in trust as herein provided for the benefit of the
holders of the Certificates, subject to the rights of such holders under the
Certificate Indenture, from and after such date until termination of the Trust
as herein provided, or under the Basic Documents.

               (c) Legal title to the Trust Property shall be vested at all
times in the Trust as a separate legal entity except where applicable law in any
jurisdiction requires title to any part of the Trust Property to be vested in a
trustee or trustees, in which case title shall be deemed to be vested in the
Delaware Trustee, a co-trustee and/or a separate trustee, as the case may be.

         SECTION 2.6 Issuance of Certificates. The Trust shall execute and
deliver the Certificates only upon satisfaction of the terms of the Certificate
Indenture. The Certificates of each Class shall represent undivided beneficial
interests in the assets of the Trust consisting of the Notes of the
corresponding Class and payments thereon, and shall be issued in accordance with
the terms of the Certificate Indenture.

         SECTION 2.7 Organizational Expenses. The Delaware Trustee shall be
reimbursed, but solely from amounts payable by the Note Issuer under a fee and
indemnity agreement (the "Fee and Indemnity Agreement"), for organizational
expenses of the Trust as they may arise. The Delaware Trustee shall have no
recourse against the Agencies or against the Notes or the payments thereon and
proceeds thereof, for the reimbursement of such expenses.

         SECTION 2.8 No Liability of the Agencies or Agency Personnel. No
recourse shall be had by the Delaware Trustee for any claim based on this
Declaration, the Certificates, the Notes or the Basic Documents against any
member, director, officer, employee, agent or attorney of the Agencies unless
such claim is based upon the bad faith, fraud or deceit of such person. No
covenant, stipulation, obligation or agreement of the Agencies contained in this
Declaration shall be deemed to be a covenant, stipulation, obligation or
agreement of any present or future member, director, officer, employee or agent
of the Agencies in his or her individual capacity, and any member, director,
officer, employee, agent or attorney of the Agencies executing and delivering or
directing the execution and delivery of the Certificates shall not be liable
personally thereon or be subject to any personal liability or accountability by
reason of the issuance of the Certificates.

         SECTION 2.9 Independent Status. The Trust and each of the Agencies each
covenant and agree to hold itself out to the public under its own name as a
separate and distinct entity and


                                       4
<PAGE>   8
will each conduct its business so as not to mislead others as to its identity.
The Trust shall cause those financial statements and other records required by
law, or otherwise required, to be prepared and maintained separate and apart
from those of the Agencies.

         SECTION 2.10 Tax Treatment; Construction.

               (a) It is the intention of the parties hereto that the Trust
shall be treated as a "grantor trust" for federal income tax purposes and all
transactions contemplated by this Declaration will be reported consistently with
such treatment.

               (b) The provisions of this Declaration shall be construed, and
the affairs of the Trust shall be conducted, so as to achieve treatment of the
Trust as a "grantor trust" for federal income tax purposes. Accordingly,
notwithstanding any other provision hereof to the contrary, this Declaration
shall be construed to establish a class or classes of ownership interests, with
each class representing undivided beneficial interests in a separate specified
asset or set of assets of the Trust and facilitating the direct investment in
such assets by the holders of the Certificates. The assets of the Trust shall
consist of the Notes and other assets described in this Declaration, and the
Delaware Trustee shall have no power hereunder to vary the investment of the
holders of the Certificates.

                                   ARTICLE 3

                          DELIVERY OF CERTAIN DOCUMENTS

         SECTION 3.1 Documents Relating to Issuance of Certificates. The
Delaware Trustee is hereby directed to execute and deliver on behalf of the
Trust from time to time and as instructed in writing by the Agencies, all Basic
Documents to which the Trust or the Delaware Trustee may be a party, including
the Certificate Indenture, and any amendment or supplement thereto, the Note
Purchase Agreement, the Fee and Indemnity Agreement, the Underwriting Agreement,
and all other documents and instruments as may be necessary or desirable to
issue the Certificates pursuant to the provisions of the Certificate Indenture
and to purchase the Notes pursuant to the Note Purchase Agreement.

         SECTION 3.2 Compliance with Securities Laws. The Delaware Trustee is
hereby authorized to take such action as it may deem necessary or desirable to
comply with applicable state and federal securities laws in connection with the
offering, sale and issuance of the Certificates or the administration of the
Trust.

                                   ARTICLE 4

                              THE DELAWARE TRUSTEE

         SECTION 4.1 Appointment. For valuable consideration received, it is
mutually covenanted and agreed that the Delaware Trustee has been and by this
document is, appointed to serve as the trustee of the Trust in the State of
Delaware pursuant to Section 3807 of the Business Trust Act.

that, except as provided in Section 2.4 hereof, the duties and responsibilities
of the Delaware Trustee shall be limited to (a) executing and delivering on

into this Declaration against the Delaware Trustee.

         SECTION 4.3 Prohibited Actions. Except as otherwise expressed herein
and as permitted under the Basic Documents, the Delaware Trustee shall not (i)
take any action with respect to any election by the Trust to file an amendment
to this Declaration, (ii) amend, change, modify or terminate any Basic Document,
or (iii) sell the Notes, any other Trust Property or any interest therein.

         SECTION 4.4 Acceptance of the Trusts. By the execution hereof, the
Delaware Trustee accepts the trusts created hereinabove.

         SECTION 4.5 Limitation of Liability. Except as otherwise expressly
required by this Declaration, the Delaware Trustee shall not have any duty or
liability with respect to the administration of the Trust, the investment of the
Trust's property or the payment of dividends or other distributions of income or
principal to the holders of the Certificates. The Delaware Trustee shall not be
liable for the acts or omissions of the Certificate Trustee, nor shall the
Delaware Trustee be liable for supervising or monitoring the performance of the
duties and obligations of the Certificate Trustee. The Delaware Trustee shall
not be personally liable under any circumstances, except for its own willful
misconduct or gross negligence. In particular, but not by way of limitation:

               (a) the Delaware Trustee shall not be personally liable for any
error of judgment made in good faith by any officer within the corporate trust

creating any liability of The Bank of New York (Delaware), individually or

affiliates, such as The Bank of New York), attorneys, custodians or nominees
pursuant to agreements entered into with any of them, and the Delaware Trustee
shall not be liable for the default or misconduct or supervision of such agents,
attorneys, custodians or nominees if such agents, attorneys, custodians or
nominees shall have been selected by the Delaware Trustee in good faith and (ii)
may, at the expense of the Note Issuer, consult with attorneys, accountants and
other skilled persons to be selected in good faith and employed by it, and it
shall not be liable for anything done, suffered or omitted in good faith by it
in accordance with the advice or opinion of any such attorneys, accountants or
other skilled persons;

               (f) except as expressly provided in this Section 4.5, in
accepting and performing the trusts hereby created, the Delaware Trustee acts
solely as trustee for the Trust and not in its individual capacity, and all
persons having any claim against the Delaware Trustee by reason of the
transactions contemplated by this Declaration shall look only to the Trust's
property for payment or satisfaction thereof;

               (g) the Delaware Trustee's sole duty with respect to the custody,
safekeeping and physical preservation of the Trust Property shall be to deal
with such property in a manner similar to the manner in which the Delaware
Trustee deals with similar property for its own account, subject to the
protections and limitations on liability afforded to the Delaware Trustee under
this Declaration;

               (h) the Delaware Trustee shall have no duty or liability for or

               (k) the Delaware Trustee shall have the right at any time to seek
instructions concerning the administration of the Trust from any court of
competent jurisdiction.

         SECTION 4.6 Compensation and Reimbursement; Indemnification.

               (a) Pursuant to the Fee and Indemnity Agreement, the Note Issuer
has agreed to pay, or cause to be paid, to the Delaware Trustee from time to
time compensation for its services and to reimburse it for its reasonable
expenses hereunder. The Delaware Trustee shall have no recourse against the
Agencies or against the Notes, the payments received thereon or the proceeds
therefrom, for the payment of such compensation or for the reimbursement of such
expenses.

               (b) Pursuant to the Fee and Indemnity Agreement, the Note Issuer
has agreed to indemnify, defend and hold harmless the Delaware Trustee and any
of the affiliates, officers, directors, employees and agents of the Delaware
Trustee (the "Delaware Trustee Indemnified Persons") from and against any and
all losses, claims, actions, suits, taxes, damages, costs, expenses (including
the reasonable fees and expenses of its counsel) and liabilities (including
liabilities under state or federal securities laws) of any kind and nature
whatsoever (collectively, "Delaware Trustee Expenses"), to the extent that such
Delaware Trustee Expenses arise out of or are imposed upon or asserted against
such Delaware Trustee Indemnified Persons with respect to the creation,
operation or termination of the Trust, the execution, delivery or performance of
this Declaration or the transactions contemplated hereby; provided, however,
that the Note Issuer is not, and shall not be, required to indemnify any
Delaware Trustee Indemnified Person for any Delaware Trustee Expenses that
result from the willful misconduct or gross negligence of such Delaware Trustee
Indemnified Person. Pursuant to the Fee and Indemnity Agreement, the obligations
of the Note Issuer to indemnify the Delaware Trustee Indemnified Persons shall
survive the termination of this Declaration and the resignation or removal of
the Delaware Trustee. The Delaware Trustee is hereby authorized to execute the
Fee and Indemnity Agreement on behalf of the Trust and to enforce the terms
thereof on its own behalf and on behalf of the Trust.

               (c) Notwithstanding anything to the contrary in this Declaration,
the Delaware Trustee shall have no recourse against the Agencies or against the
Notes or the payments thereon and proceeds thereof, for payment of any amounts
required to be paid to the Delaware Trustee under the Fee and Indemnity
Agreement. The Delaware Trustee shall have a lien against the Transition
Property to secure payment of such amounts to the extent provided in the Statute
or the financing order issued pursuant thereto. The Note Issuer's obligations to
make payments of such amounts to the Delaware Trustee shall be subject to the
priorities set forth in Section 8.02 of the Note Indenture.

         SECTION 4.7 Resignation. The Delaware Trustee may resign upon 30 days'
prior written notice to the Certificate Trustee, the Agencies and the Trust;
provided, however, that a successor Delaware Trustee satisfactory to the
Agencies shall have been appointed and agreed to serve. If a successor Delaware
Trustee shall not have been appointed by the Agencies within such 30-day period,
the Delaware Trustee may apply to the Court of Chancery of the State of Delaware
for the appointment of a successor Delaware Trustee. Any successor Delaware
Trustee must satisfy the requirement of Section 3807(a) of the Business Trust
Act.

         SECTION 4.8 Representations and Warranties of Delaware Trustee. The
Bank of New York (Delaware) hereby represents and warrants to the other parties
hereto that:

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

               (b) It has full power, authority and legal right to execute,
deliver and perform this Declaration, and has taken all necessary action to
authorize the execution, delivery and performance by it of this Declaration.

               (c) The execution, delivery and performance by it of this
Declaration (i) do not violate any requirement of federal law or the law of the
State of Delaware governing its banking and trust powers or any order, writ,
judgment or decree of any court, arbitrator or governmental authority applicable
to it or any of its assets, (ii) do not violate any provision of its charter or
by-laws, and (iii) do not violate any provision of, or constitute, with or
without notice or lapse of time, a default under, or result in the creation or
imposition of any Lien on any properties included in the Trust pursuant to the
provisions of any mortgage, indenture, contract, agreement or other undertaking
to which it is a party, which violation, default or Lien could reasonably be
expected to have a materially adverse effect on its performance or its ability
to perform its duties as a Trustee under this Declaration or on the transactions
contemplated in this Declaration.

               (d) Its execution, delivery and performance of this Declaration
shall not require the authorization, consent or approval of, the giving of
notice to, the filing or registration with, or the taking of any other action in
respect of, any governmental authority or agency regulating the banking and
corporate trust activities of banks or trust companies in the jurisdiction in
which the Trust was formed (except for the filing of the Certificate of Trust
with the Secretary of State of the State of Delaware).

               (e) This Declaration has been duly executed and delivered by it
and, assuming due authorization, execution and delivery hereof by the other
parties hereto, constitutes the legal, valid and binding agreement of it,
enforceable against it in accordance with the terms of this Declaration, except
as enforceability may be limited by bankruptcy, insolvency, reorganization, and
other similar laws affecting the enforcement of creditors' rights in general and
by general principles of equity, regardless of whether such enforceability is
considered in a proceeding in equity or at law.

         SECTION 4.9 Reliance; Advice of Counsel.

               (a) The Delaware Trustee shall incur no liability to anyone in
acting upon any signature, instrument, notice, resolution, request, consent,
order, certificate, report, opinion, bond or other document or paper reasonably
believed by it to be genuine and reasonably believed by it to be signed by the
proper party or parties and need not investigate any fact or matter pertaining
to or in any such document. The Delaware Trustee may accept a certified copy of
a resolution of the board of directors or other governing body of any corporate
party as conclusive evidence that such resolution has been duly adopted by such
body and that the same is in full force and effect unless and until the Delaware
Trustee receives a certified copy of a resolution of such board of directors or
other body revoking the same. As to any fact or matter the method of the


                                       9
<PAGE>   13
determination of which is not specifically prescribed herein, the Delaware
Trustee may for all purposes hereof rely on a certificate, signed by the
president or any vice president or by the treasurer or other authorized officers
of the relevant party, as to such fact or matter, and such certificate shall
constitute full protection to it for any action taken or omitted to be taken by
it in good faith in reliance thereon.

               (b) In the exercise or administration of the trusts hereunder and
in the performance of its duties and obligations under this Declaration and the
Basic Documents, the Delaware Trustee: (i) may, at the expense of the Note
Issuer or any other party, to the extent provided in the Fee and Indemnity
Agreement, act directly or through its agents, attorneys, custodians or nominees
(including, if necessary, the granting of a power of attorney to any of its
officers not otherwise authorized to execute and deliver any Basic Document,
Certificate or other documents related thereto and to take any action in
connection therewith on behalf of the Delaware Trustee) pursuant to agreements
entered into with any of them, and the Delaware Trustee shall not be liable for
the conduct or misconduct of such agents, attorneys, custodians or nominees if
such agents, attorneys, custodians or nominees shall have been selected by the
Delaware Trustee with reasonable care; and (ii) may, at the expense of the Note
Issuer or any other party, to the extent provided in the Fee and Indemnity
Agreement, consult with counsel, accountants and other professionals to be
selected with reasonable care by it. The Delaware Trustee shall not be liable
for anything done, suffered or omitted in good faith by it in accordance with
the opinion or advice of any such counsel, accountant or other such persons
reasonably relied on and which, according to such opinion or advice, is not
contrary to this Declaration or any other Basic Document.

         SECTION 4.10 Delaware Trustee May Own Certificates. The Delaware
Trustee in its individual or any other capacity may become the owner or pledgee
of Certificates and may deal with Boston Edison, the Note Issuer, the Note
Trustee, the Certificate Trustee, the Servicer, the Agencies and their
respective affiliates and with the holders of the Certificates in transactions
in the same manner as the Delaware Trustee would have if it were not a trustee
under this Declaration.

has taken all action necessary, to execute and deliver this Declaration and to
fulfill its obligations under, and to consummate the transactions contemplated
by, this Declaration;

               (b) the making and performance by such Agency of this Declaration
and all documents required to be executed and delivered by it hereunder do not
and will not violate any law or regulation of the jurisdiction of its
organization or any other law or regulation applicable to it or violate any
provision of, or constitute, with or without notice or lapse of time, a default
under, or result in the creation or imposition of any lien on any properties
included in the Trust

<PAGE>   14
Property pursuant to, any mortgage, indenture, contract, agreement or other
undertaking to which such Agency is a party;

               (c) this Declaration has been duly executed and delivered by such
Agency and constitutes its legal, valid and binding obligation, enforceable in
accordance with its terms; and

               (d) to the best knowledge of such Agency, all consents, licenses,
approvals, authorizations, exemptions, registrations, filings, opinions and
declarations from or with any agency, department, administrative authority,
statutory corporation or judicial entity necessary for the validity or
enforceability of such Agency's obligations under this Declaration have been

class of all amounts required to be distributed to them pursuant to the
Certificate Indenture and the disposition of all property held as part of the
Trust Property with respect to such class of Certificates. Upon the redemption
of all classes of Certificates and at the election of the Agencies, the Trust
shall dissolve. The Agencies shall pay or provide for the payment of all
remaining liabilities of the Trust and the Delaware Trustee, but solely from
amounts payable to the Agencies under the Fee and Indemnity Agreement, and
thereupon the Delaware Trustee shall file a certificate of cancellation under
the Business Trust Act and the Trust shall terminate, and any fees associated

amount of each affected class of the Certificates as of the close of business on
the preceding Certificate payment date (which consent, whether given pursuant to
this Section 7.6 or pursuant to any other provision of this Declaration or the
Certificate Indenture, shall be conclusive and binding on such Certificate
holder and on all future holders of such Certificates and of any Certificates
issued upon the transfer thereof or in exchange thereof or in lieu thereof

of the provisions of this Declaration, or of modifying in any manner the rights
of the holders of the Certificates; provided, however, that no such amendment
shall (a) increase or reduce in any manner the amount of, or accelerate or delay
the timing of, payments that shall be required to be made on any Certificate
without the consent of the holder thereof; (b) adversely affect the rating of
any of the Certificates without the consent of the holders of all of the
outstanding principal amount of such affected Certificates; or (c) reduce the
aforesaid majority required to consent to any such amendment, without the
consent of all of the holders of the Certificates then outstanding. Prior to the
execution of any such amendment, supplement or consent, the Delaware Trustee
shall furnish written notification of the substance of such amendment,
supplement or consent to the rating agencies named in the Certificate Indenture.
After the execution of any such amendment, supplement or consent, the Delaware
Trustee shall furnish a copy thereof to the rating agencies named in the
Certificate Indenture.

Basic Document) and of evidencing the authorization of the execution thereof by
holders of the Certificates shall be subject to such reasonable requirements as
the Delaware Trustee may prescribe to the extent not inconsistent with the
provisions of the Basic Documents.

the execution of such amendment is authorized or permitted by this Declaration
and (ii) such execution will not adversely affect the treatment of the Trust as
a "grantor trust" for federal income tax purposes.

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

shall be binding upon, and inure to the benefit of the Agencies, the Trust and
the Delaware Trustee and their respective successors and permitted assigns, all

ordering the winding up or liquidation of the affairs of the Trust.

Sections herein are for convenience of reference only and shall not define or
limit any of the terms or provisions hereof.

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT
REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH

         This Class A-1 Note is one of a duly authorized issue of Notes of the
Note Issuer, designated as its BEC Funding LLC Notes (herein called the
"Notes"), issued and to be issuable in one or more Classes, and further
designated as a Class A-1 Note (collectively with all other Class A-1 Notes of
this issue, the "Class A-1 Notes"), all issued and to be issued under a Note
Indenture dated as of July 29, 1999 (the "Note Indenture"), between the Note
Issuer and The Bank of New York, as Note Trustee (the "Note Trustee," which term
includes any successor trustee under the Note Indenture), to which Note
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights and obligations thereunder of the Note
Issuer, the Note Trustee and the Holders of the Notes. All terms used in this
Class A-1 Note that are defined in the Note Indenture, as supplemented or
amended, shall have the meanings assigned to them in the Note Indenture, as
supplemented or amended.

         The Class A-1 Notes and the other Classes of Notes issued by the Note
Issuer are and will be equally and ratably secured by the collateral pledged as
security therefor, as provided in the Note Indenture.

         The principal of this Class A-1 Note shall be payable on each Payment
Date only to the extent that amounts in the Collection Account are available
therefor, and only until the outstanding principal balance thereof on such
Payment Date (after giving effect to all payments of principal, if any, made on
such Payment Date) has been reduced to the principal balance specified in the
Expected Amortization Schedule which is attached to the Note Indenture as
Schedule A, unless payable earlier either because (x) an Event of Default shall
have occurred and be continuing and the Note Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes
have declared the Notes to be immediately due and payable in accordance with
Section 5.02 of the Note Indenture, (y) the Note Issuer, at its option, shall
have called for the redemption of the Notes pursuant to Section 10.01 of the
Note Indenture or (z) the Note Issuer shall have called for the redemption of
the Notes pursuant to Section 10.04 of the Note Indenture if the Seller is
required to repurchase the Transition Property pursuant to Section 5.01 of the
Sale Agreement. However, actual principal payments may be made in lesser than
expected amounts and at later than expected times as determined pursuant to
Section 8.02 of the Note Indenture. The entire unpaid principal amount of this
Class A-1 Note shall be due and payable on the earlier of the Final Maturity
Date hereof, the optional Redemption Date, if any, and the Mandatory Redemption
Date, if any, herefor. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not then previously
paid, on the date on which an Event of Default shall have occurred and be
continuing and the Note Trustee or the Holders of the Notes representing not
less than a majority of the Outstanding Amount of the Notes have declared the
Notes to be immediately due and payable in the manner provided in Section 5.02
of the Note Indenture. All principal payments on the Class A-1 Notes shall be
made pro rata to the Class A-1 Noteholders entitled thereto based on the
respective principal amounts of the Class A-1 Notes held by them.

<PAGE>   6
         Payments of interest on this Class A-1 Note due and payable on each
Payment Date, together with the installment of principal shall be made by check
mailed first-class, postage prepaid, to the Person whose name appears as the
Registered Holder of this Class A-1 Note (or one or more Predecessor Notes) on
the Note Register as of the close of business on the Record Date, except that
with respect to Notes registered on the Record Date in the name of the
Certificate Trustee, payments will be made by wire transfer in immediately
available funds to the account designated by the Certificate Trustee and except
for the final installment of principal payable with respect to this Class A-1
Note on a Payment Date which shall be payable as provided below. Such checks
shall be mailed to the Person entitled thereto at the address of such Person as
it appears on the Note Register as of the applicable Record Date without
requiring that this Class A-1 Note be submitted for notation of payment. Any
reduction in the principal amount of this Class A-1 Note (or any one or more
Predecessor Notes) effected by any payments made on any Payment Date shall be
binding upon all future Holders of this Class A-1 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not noted hereon. If funds are expected to be available, as
provided in the Note Indenture, for payment in full of the then remaining unpaid
principal amount of this Class A-1 Note on a Payment Date, then the Note
Trustee, in the name of and on behalf of the Note Issuer, will notify the Person
who was the Registered Holder hereof as of the Record Date preceding such
Payment Date by notice mailed no later than five days prior to such final
Payment Date and shall specify that such final installment will be payable only
upon presentation and surrender of this Class A-1 Note and shall specify the
place where this Class A-1 Note may be presented and surrendered for payment of
such installment.

         The Note Issuer shall pay interest on overdue installments of interest
at the Note Interest Rate to the extent lawful.

         As provided in the Note Indenture, the Class A-1 Notes may be redeemed,
in whole but not in part, at the option of the Note Issuer on any Payment Date
at the Optional Redemption Price if, after giving effect to payments that would
otherwise be made on such Payment Date, the Outstanding Amount of the Notes has
been reduced to less than five percent of the initial principal balance thereof.
In addition, as provided in the Note Indenture, if the Seller is required to
repurchase the Transition Property pursuant to Section 5.01 of the Sale
Agreement, the Note Issuer will be required to redeem all outstanding Notes,
including the Class A-1 Notes, on or before the fifth Business Day following the
Repurchase Date (as defined in the Sale Agreement).

         As provided in the Note Indenture and subject to certain limitations
set forth therein, the transfer of this Class A-1 Note may be registered on the
Note Register upon surrender of this Class A-1 Note for registration of transfer
at the office or agency designated by the Note Issuer pursuant to the Note
Indenture, duly endorsed by, or accompanied by (a) a written instrument of
transfer in form satisfactory to the Note Trustee duly executed by the Holder
hereof or his attorney duly authorized in writing, with such signature
guaranteed by an institution which is a member of one of the following
recognized Signature Guaranty Programs: (i) The Securities Transfer Agent
Medallion Program (STAMP); (ii) The New York Stock Exchange Medallion

<PAGE>   7
Program (MSP); (iii) The Stock Exchange Medallion Program (SEMP); or (iv) in
such other guarantee program acceptable to the Note Trustee, and (b) such other
documents as the Note Trustee may require, and thereupon one or more new Class
A-1 Notes of Minimum Denominations and in the same aggregate principal amount
will be issued to the designated transferee or transferees. No service charge
will be charged for any registration of transfer or exchange of this Class A-1
Note, but the transferor may be required to pay a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any such
registration of transfer or exchange, other than exchanges pursuant to Section
2.04 of the Note Indenture not involving any transfer.

         Each Noteholder, by acceptance of a Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Note Issuer or the Note Trustee on the Notes or under the Note Indenture
or any certificate or other writing delivered in connection therewith, against
(i) the Note Trustee in its individual capacity, (ii) any owner of a beneficial
interest in the Note Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director or employee of the Note Trustee in its individual capacity,
any holder of a beneficial interest in the Note Issuer or the Note Trustee or of
any successor or assign of the Note Trustee in its individual capacity, except
as any such Person may have expressly agreed (it being understood that the Note
Trustee has no such obligations in its individual capacity).

         Prior to the due presentment for registration of transfer of this Class
A-1 Note, the Note Issuer, the Note Trustee and any agent of the Note Issuer or
the Note Trustee may treat the Person in whose name this Class A-1 Note is
registered (as of the day of determination) as the owner hereof for the purpose
of receiving payments of principal of and interest on this Class A-1 Note and
for all other purposes whatsoever, whether or not this Class A-1 Note be
overdue, and neither the Note Issuer, the Note Trustee nor any such agent shall
be affected by notice to the contrary.

         The Note Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Note Issuer and the rights of the Holders of the Notes under
the Note Indenture at any time by the Note Issuer with the consent of the
Holders of Notes representing a majority of the Outstanding Amount of all Notes
at the time Outstanding of each Class to be affected. The Note Indenture also
contains provisions permitting the Holders of Notes representing specified
percentages of the Outstanding Amount of the Notes, on behalf of the Holders of
all the Notes, to waive compliance by the Note Issuer with certain provisions of
the Note Indenture and certain past defaults under the Note Indenture and their
consequences. Any such consent or waiver by the Holder of this Class A-1 Note
(or any one of more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Class A-1 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Class A-1
Note. The Note Indenture also permits the Note Trustee to amend or waive certain
terms and conditions set forth in the Note Indenture without the consent of
Holders of the Notes issued thereunder.

         The term "Note Issuer" as used in this Class A-1 Note includes any
successor to the Note Issuer under the Note Indenture.

         The Note Issuer is permitted by the Note Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Note
Trustee and the Holders of Notes under the Note Indenture.

         The Class A-1 Notes are issuable only in registered form in
denominations as provided in the Note Indenture, subject to certain limitations
therein set forth.

         This Class A-1 Note and the Note Indenture shall be construed in
accordance with the laws of The Commonwealth of Massachusetts, without reference
to its conflict of law provisions, and the obligations, rights and remedies of
the parties hereunder and thereunder shall be determined in accordance with such
laws.

         No reference herein to the Note Indenture and no provision of this
Class A-1 Note or of the Note Indenture shall alter or impair the obligation of
the Note Issuer, which is absolute and unconditional, to pay the principal of
and interest on this Class A-1 Note at the times, place, and rate, and in the
coin or currency herein prescribed.

         The Holder of this Class A-1 Note by the acceptance hereof agrees that,
notwithstanding any provision of the Note Indenture to the contrary, the Holder
shall have no recourse against the Note Issuer, but shall look only to the
Collateral, with respect to any amounts due to the Holder under this Class A-1
Note.

                                [REVERSE OF NOTE]


         This Class A-2 Note is one of a duly authorized issue of Notes of the
Note Issuer, designated as its BEC Funding LLC Notes (herein called the
"Notes"), issued and to be issuable in one or more Classes, and further
designated as a Class A-2 Note (collectively with all other Class A-2 Notes of
this issue, the "Class A-2 Notes"), all issued and to be issued under a Note
Indenture dated as of July 29, 1999 (the "Note Indenture"), between the Note
Issuer and The Bank of New York, as Note Trustee (the "Note Trustee," which term
includes any successor trustee under the Note Indenture), to which Note
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights and obligations thereunder of the Note
Issuer, the Note Trustee and the Holders of the Notes. All terms used in this
Class A-2 Note that are defined in the Note Indenture, as supplemented or
amended, shall have the meanings assigned to them in the Note Indenture, as
supplemented or amended.

         The Class A-2 Notes and the other Classes of Notes issued by the Note
Issuer are and will be equally and ratably secured by the collateral pledged as
security therefor, as provided in the Note Indenture.

         The principal of this Class A-2 Note shall be payable on each Payment
Date only to the extent that amounts in the Collection Account are available
therefor, and only until the outstanding principal balance thereof on such
Payment Date (after giving effect to all payments of principal, if any, made on
such Payment Date) has been reduced to the principal balance specified in the
Expected Amortization Schedule which is attached to the Note Indenture as
Schedule A, unless payable earlier either because (x) an Event of Default shall
have occurred and be continuing and the Note Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes
have declared the Notes to be immediately due and payable in accordance with
Section 5.02 of the Note Indenture, (y) the Note Issuer, at its option, shall
have called for the redemption of the Notes pursuant to Section 10.01 of the
Note Indenture or (z) the Note Issuer shall have called for the redemption of
the Notes pursuant to Section 10.04 of the Note Indenture if the Seller is
required to repurchase the Transition Property pursuant to Section 5.01 of the
Sale Agreement. However, actual principal payments may be made in lesser than
expected amounts and at later than expected times as determined pursuant to
Section 8.02 of the Note Indenture. The entire unpaid principal amount of this
Class A-2 Note shall be due and payable on the earlier of the Final Maturity
Date hereof, the optional Redemption Date, if any, and the Mandatory Redemption
Date, if any, herefor. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not then previously
paid, on the date on which an Event of Default shall have occurred and be
continuing and the Note Trustee or the Holders of the Notes representing not
less than a majority of the Outstanding Amount of the Notes have declared the
Notes to be immediately due and payable in the manner provided in Section 5.02
of the Note Indenture. All principal payments on the Class A-2 Notes shall be
made pro rata to the Class A-2 Noteholders entitled thereto based on the
respective principal amounts of the Class A-2 Notes held by them.

<PAGE>   15
         Payments of interest on this Class A-2 Note due and payable on each
Payment Date, together with the installment of principal shall be made by check
mailed first-class, postage prepaid, to the Person whose name appears as the
Registered Holder of this Class A-2 Note (or one or more Predecessor Notes) on
the Note Register as of the close of business on the Record Date, except that
with respect to Notes registered on the Record Date in the name of the
Certificate Trustee, payments will be made by wire transfer in immediately
available funds to the account designated by the Certificate Trustee and except
for the final installment of principal payable with respect to this Class A-2
Note on a Payment Date which shall be payable as provided below. Such checks
shall be mailed to the Person entitled thereto at the address of such Person as
it appears on the Note Register as of the applicable Record Date without
requiring that this Class A-2 Note be submitted for notation of payment. Any
reduction in the principal amount of this Class A-2 Note (or any one or more
Predecessor Notes) effected by any payments made on any Payment Date shall be
binding upon all future Holders of this Class A-2 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not noted hereon. If funds are expected to be available, as
provided in the Note Indenture, for payment in full of the then remaining unpaid
principal amount of this Class A-2 Note on a Payment Date, then the Note
Trustee, in the name of and on behalf of the Note Issuer, will notify the Person
who was the Registered Holder hereof as of the Record Date preceding such
Payment Date by notice mailed no later than five days prior to such final
Payment Date and shall specify that such final installment will be payable only
upon presentation and surrender of this Class A-2 Note and shall specify the
place where this Class A-2 Note may be presented and surrendered for payment of
such installment.

         The Note Issuer shall pay interest on overdue installments of interest
at the Note Interest Rate to the extent lawful.

         As provided in the Note Indenture, the Class A-2 Notes may be redeemed,
in whole but not in part, at the option of the Note Issuer on any Payment Date
at the Optional Redemption Price if, after giving effect to payments that would
otherwise be made on such Payment Date, the Outstanding Amount of the Notes has
been reduced to less than five percent of the initial principal balance thereof.
In addition, as provided in the Note Indenture, if the Seller is required to
repurchase the Transition Property pursuant to Section 5.01 of the Sale
Agreement, the Note Issuer will be required to redeem all outstanding Notes,
including the Class A-2 Notes, on or before the fifth Business Day following the
Repurchase Date (as defined in the Sale Agreement).

         As provided in the Note Indenture and subject to certain limitations
set forth therein, the transfer of this Class A-2 Note may be registered on the
Note Register upon surrender of this Class A-2 Note for registration of transfer
at the office or agency designated by the Note Issuer pursuant to the Note
Indenture, duly endorsed by, or accompanied by (a) a written instrument of
transfer in form satisfactory to the Note Trustee duly executed by the Holder
hereof or his attorney duly authorized in writing, with such signature
guaranteed by an institution which is a member of one of the following
recognized Signature Guaranty Programs: (i) The Securities Transfer Agent
Medallion Program (STAMP); (ii) The New York Stock Exchange Medallion

<PAGE>   16
Program (MSP); (iii) The Stock Exchange Medallion Program (SEMP); or (iv) in
such other guarantee program acceptable to the Note Trustee, and (b) such other
documents as the Note Trustee may require, and thereupon one or more new Class
A-2 Notes of Minimum Denominations and in the same aggregate principal amount
will be issued to the designated transferee or transferees. No service charge
will be charged for any registration of transfer or exchange of this Class A-2
Note, but the transferor may be required to pay a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any such
registration of transfer or exchange, other than exchanges pursuant to Section
2.04 of the Note Indenture not involving any transfer.

         Each Noteholder, by acceptance of a Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Note Issuer or the Note Trustee on the Notes or under the Note Indenture
or any certificate or other writing delivered in connection therewith, against
(i) the Note Trustee in its individual capacity, (ii) any owner of a beneficial
interest in the Note Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director or employee of the Note Trustee in its individual capacity,
any holder of a beneficial interest in the Note Issuer or the Note Trustee or of
any successor or assign of the Note Trustee in its individual capacity, except
as any such Person may have expressly agreed (it being understood that the Note
Trustee has no such obligations in its individual capacity).

         Prior to the due presentment for registration of transfer of this Class
A-2 Note, the Note Issuer, the Note Trustee and any agent of the Note Issuer or
the Note Trustee may treat the Person in whose name this Class A-2 Note is
registered (as of the day of determination) as the owner hereof for the purpose
of receiving payments of principal of and interest on this Class A-2 Note and
for all other purposes whatsoever, whether or not this Class A-2 Note be
overdue, and neither the Note Issuer, the Note Trustee nor any such agent shall
be affected by notice to the contrary.

         The Note Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Note Issuer and the rights of the Holders of the Notes under
the Note Indenture at any time by the Note Issuer with the consent of the
Holders of Notes representing a majority of the Outstanding Amount of all Notes
at the time Outstanding of each Class to be affected. The Note Indenture also
contains provisions permitting the Holders of Notes representing specified
percentages of the Outstanding Amount of the Notes, on behalf of the Holders of
all the Notes, to waive compliance by the Note Issuer with certain provisions of
the Note Indenture and certain past defaults under the Note Indenture and their
consequences. Any such consent or waiver by the Holder of this Class A-2 Note
(or any one of more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Class A-2 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Class A-2
Note. The Note Indenture also permits the Note Trustee to amend or waive certain
terms and conditions set forth in the Note Indenture without the consent of
Holders of the Notes issued thereunder.

         The term "Note Issuer" as used in this Class A-2 Note includes any
successor to the Note Issuer under the Note Indenture.

         The Note Issuer is permitted by the Note Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Note
Trustee and the Holders of Notes under the Note Indenture.

         The Class A-2 Notes are issuable only in registered form in
denominations as provided in the Note Indenture, subject to certain limitations
therein set forth.

         This Class A-2 Note and the Note Indenture shall be construed in
accordance with the laws of The Commonwealth of Massachusetts, without reference
to its conflict of law provisions, and the obligations, rights and remedies of
the parties hereunder and thereunder shall be determined in accordance with such
laws.

         No reference herein to the Note Indenture and no provision of this
Class A-2 Note or of the Note Indenture shall alter or impair the obligation of
the Note Issuer, which is absolute and unconditional, to pay the principal of
and interest on this Class A-2 Note at the times, place, and rate, and in the
coin or currency herein prescribed.

         The Holder of this Class A-2 Note by the acceptance hereof agrees that,
notwithstanding any provision of the Note Indenture to the contrary, the Holder
shall have no recourse against the Note Issuer, but shall look only to the
Collateral, with respect to any amounts due to the Holder under this Class A-2
Note.

         This Class A-4 Note is one of a duly authorized issue of Notes of the
Note Issuer, designated as its BEC Funding LLC Notes (herein called the
"Notes"), issued and to be issuable in one or more Classes, and further
designated as a Class A-4 Note (collectively with all other Class A-4 Notes of
this issue, the "Class A-4 Notes"), all issued and to be issued under a Note
Indenture dated as of July 29, 1999 (the "Note Indenture"), between the Note
Issuer and The Bank of New York, as Note Trustee (the "Note Trustee," which term
includes any successor trustee under the Note Indenture), to which Note
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights and obligations thereunder of the Note
Issuer, the Note Trustee and the Holders of the Notes. All terms used in this
Class A-4 Note that are defined in the Note Indenture, as supplemented or
amended, shall have the meanings assigned to them in the Note Indenture, as
supplemented or amended.

         The Class A-4 Notes and the other Classes of Notes issued by the Note
Issuer are and will be equally and ratably secured by the collateral pledged as
security therefor, as provided in the Note Indenture.

         The principal of this Class A-4 Note shall be payable on each Payment
Date only to the extent that amounts in the Collection Account are available
therefor, and only until the outstanding principal balance thereof on such
Payment Date (after giving effect to all payments of principal, if any, made on
such Payment Date) has been reduced to the principal balance specified in the
Expected Amortization Schedule which is attached to the Note Indenture as
Schedule A, unless payable earlier either because (x) an Event of Default shall
have occurred and be continuing and the Note Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes
have declared the Notes to be immediately due and payable in accordance with
Section 5.02 of the Note Indenture, (y) the Note Issuer, at its option, shall
have called for the redemption of the Notes pursuant to Section 10.01 of the
Note Indenture or (z) the Note Issuer shall have called for the redemption of
the Notes pursuant to Section 10.04 of the Note Indenture if the Seller is
required to repurchase the Transition Property pursuant to Section 5.01 of the
Sale Agreement. However, actual principal payments may be made in lesser than
expected amounts and at later than expected times as determined pursuant to
Section 8.02 of the Note Indenture. The entire unpaid principal amount of this
Class A-4 Note shall be due and payable on the earlier of the Final Maturity
Date hereof, the optional Redemption Date, if any, and the Mandatory Redemption
Date, if any, herefor. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not then previously
paid, on the date on which an Event of Default shall have occurred and be
continuing and the Note Trustee or the Holders of the Notes representing not
less than a majority of the Outstanding Amount of the Notes have declared the
Notes to be immediately due and payable in the manner provided in Section 5.02
of the Note Indenture. All principal payments on the Class A-4 Notes shall be
made pro rata to the Class A-4 Noteholders entitled thereto based on the
respective principal amounts of the Class A-4 Notes held by them.

<PAGE>   33
         Payments of interest on this Class A-4 Note due and payable on each
Payment Date, together with the installment of principal shall be made by check
mailed first-class, postage prepaid, to the Person whose name appears as the
Registered Holder of this Class A-4 Note (or one or more Predecessor Notes) on
the Note Register as of the close of business on the Record Date, except that
with respect to Notes registered on the Record Date in the name of the
Certificate Trustee, payments will be made by wire transfer in immediately
available funds to the account designated by the Certificate Trustee and except
for the final installment of principal payable with respect to this Class A-4
Note on a Payment Date which shall be payable as provided below. Such checks
shall be mailed to the Person entitled thereto at the address of such Person as
it appears on the Note Register as of the applicable Record Date without
requiring that this Class A-4 Note be submitted for notation of payment. Any
reduction in the principal amount of this Class A-4 Note (or any one or more
Predecessor Notes) effected by any payments made on any Payment Date shall be
binding upon all future Holders of this Class A-4 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not noted hereon. If funds are expected to be available, as
provided in the Note Indenture, for payment in full of the then remaining unpaid
principal amount of this Class A-4 Note on a Payment Date, then the Note
Trustee, in the name of and on behalf of the Note Issuer, will notify the Person
who was the Registered Holder hereof as of the Record Date preceding such
Payment Date by notice mailed no later than five days prior to such final
Payment Date and shall specify that such final installment will be payable only
upon presentation and surrender of this Class A-4 Note and shall specify the
place where this Class A-4 Note may be presented and surrendered for payment of
such installment.

         The Note Issuer shall pay interest on overdue installments of interest
at the Note Interest Rate to the extent lawful.

         As provided in the Note Indenture, the Class A-4 Notes may be redeemed,
in whole but not in part, at the option of the Note Issuer on any Payment Date
at the Optional Redemption Price if, after giving effect to payments that would
otherwise be made on such Payment Date, the Outstanding Amount of the Notes has
been reduced to less than five percent of the initial principal balance thereof.
In addition, as provided in the Note Indenture, if the Seller is required to
repurchase the Transition Property pursuant to Section 5.01 of the Sale
Agreement, the Note Issuer will be required to redeem all outstanding Notes,
including the Class A-4 Notes, on or before the fifth Business Day following the
Repurchase Date (as defined in the Sale Agreement).

         As provided in the Note Indenture and subject to certain limitations
set forth therein, the transfer of this Class A-4 Note may be registered on the
Note Register upon surrender of this Class A-4 Note for registration of transfer

Note, but the transferor may be required to pay a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any such
registration of transfer or exchange, other than exchanges pursuant to Section
2.04 of the Note Indenture not involving any transfer.

         Each Noteholder, by acceptance of a Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Note Issuer or the Note Trustee on the Notes or under the Note Indenture
or any certificate or other writing delivered in connection therewith, against

interest in the Note Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director or employee of the Note Trustee in its individual capacity,
any holder of a beneficial interest in the Note Issuer or the Note Trustee or of
any successor or assign of the Note Trustee in its individual capacity, except
as any such Person may have expressly agreed (it being understood that the Note
Trustee has no such obligations in its individual capacity).

         Prior to the due presentment for registration of transfer of this Class
A-4 Note, the Note Issuer, the Note Trustee and any agent of the Note Issuer or
the Note Trustee may treat the Person in whose name this Class A-4 Note is

of receiving payments of principal of and interest on this Class A-4 Note and
for all other purposes whatsoever, whether or not this Class A-4 Note be
overdue, and neither the Note Issuer, the Note Trustee nor any such agent shall
be affected by notice to the contrary.

         The Note Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Note Issuer and the rights of the Holders of the Notes under
the Note Indenture at any time by the Note Issuer with the consent of the
Holders of Notes representing a majority of the Outstanding Amount of all Notes
at the time Outstanding of each Class to be affected. The Note Indenture also
contains provisions permitting the Holders of Notes representing specified
percentages of the Outstanding Amount of the Notes, on behalf of the Holders of
all the Notes, to waive compliance by the Note Issuer with certain provisions of
the Note Indenture and certain past defaults under the Note Indenture and their
consequences. Any such consent or waiver by the Holder of this Class A-4 Note
(or any one of more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Class A-4 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Class A-4
Note. The Note Indenture also permits the Note Trustee to amend or waive certain
terms and conditions set forth in the Note Indenture without the consent of
Holders of the Notes issued thereunder.

                                [REVERSE OF NOTE]


         This Class A-5 Note is one of a duly authorized issue of Notes of the
Note Issuer, designated as its BEC Funding LLC Notes (herein called the
"Notes"), issued and to be issuable in one or more Classes, and further
designated as a Class A-5 Note (collectively with all other Class A-5 Notes of
this issue, the "Class A-5 Notes"), all issued and to be issued under a Note
Indenture dated as of July 29, 1999 (the "Note Indenture"), between the Note
Issuer and The Bank of New York, as Note Trustee (the "Note Trustee," which term
includes any successor trustee under the Note Indenture), to which Note
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights and obligations thereunder of the Note
Issuer, the Note Trustee and the Holders of the Notes. All terms used in this
Class A-5 Note that are defined in the Note Indenture, as supplemented or
amended, shall have the meanings assigned to them in the Note Indenture, as
supplemented or amended.

         The Class A-5 Notes and the other Classes of Notes issued by the Note
Issuer are and will be equally and ratably secured by the collateral pledged as
security therefor, as provided in the Note Indenture.

         The principal of this Class A-5 Note shall be payable on each Payment
Date only to the extent that amounts in the Collection Account are available
therefor, and only until the outstanding principal balance thereof on such
Payment Date (after giving effect to all payments of principal, if any, made on
such Payment Date) has been reduced to the principal balance specified in the
Expected Amortization Schedule which is attached to the Note Indenture as
Schedule A, unless payable earlier either because (x) an Event of Default shall
have occurred and be continuing and the Note Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes
have declared the Notes to be immediately due and payable in accordance with
Section 5.02 of the Note Indenture, (y) the Note Issuer, at its option, shall
have called for the redemption of the Notes pursuant to Section 10.01 of the
Note Indenture or (z) the Note Issuer shall have called for the redemption of
the Notes pursuant to Section 10.04 of the Note Indenture if the Seller is
required to repurchase the Transition Property pursuant to Section 5.01 of the
Sale Agreement. However, actual principal payments may be made in lesser than
expected amounts and at later than expected times as determined pursuant to
Section 8.02 of the Note Indenture. The entire unpaid principal amount of this
Class A-5 Note shall be due and payable on the earlier of the Final Maturity
Date hereof, the optional Redemption Date, if any, and the Mandatory Redemption
Date, if any, herefor. Notwithstanding the foregoing, the entire unpaid
principal amount of the Notes shall be due and payable, if not then previously
paid, on the date on which an Event of Default shall have occurred and be
continuing and the Note Trustee or the Holders of the Notes representing not
less than a majority of the Outstanding Amount of the Notes have declared the
Notes to be immediately due and payable in the manner provided in Section 5.02
of the Note Indenture. All principal payments on the Class A-5 Notes shall be
made pro rata to the Class A-5 Noteholders entitled thereto based on the
respective principal amounts of the Class A-5 Notes held by them.


                                       5
<PAGE>   42
         Payments of interest on this Class A-5 Note due and payable on each
Payment Date, together with the installment of principal shall be made by check
mailed first-class, postage prepaid, to the Person whose name appears as the
Registered Holder of this Class A-5 Note (or one or more Predecessor Notes) on
the Note Register as of the close of business on the Record Date, except that
with respect to Notes registered on the Record Date in the name of the
Certificate Trustee, payments will be made by wire transfer in immediately
available funds to the account designated by the Certificate Trustee and except
for the final installment of principal payable with respect to this Class A-5
Note on a Payment Date which shall be payable as provided below. Such checks
shall be mailed to the Person entitled thereto at the address of such Person as
it appears on the Note Register as of the applicable Record Date without
requiring that this Class A-5 Note be submitted for notation of payment. Any
reduction in the principal amount of this Class A-5 Note (or any one or more
Predecessor Notes) effected by any payments made on any Payment Date shall be
binding upon all future Holders of this Class A-5 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not noted hereon. If funds are expected to be available, as
provided in the Note Indenture, for payment in full of the then remaining unpaid
principal amount of this Class A-5 Note on a Payment Date, then the Note
Trustee, in the name of and on behalf of the Note Issuer, will notify the Person
who was the Registered Holder hereof as of the Record Date preceding such
Payment Date by notice mailed no later than five days prior to such final
Payment Date and shall specify that such final installment will be payable only
upon presentation and surrender of this Class A-5 Note and shall specify the
place where this Class A-5 Note may be presented and surrendered for payment of
such installment.

         The Note Issuer shall pay interest on overdue installments of interest
at the Note Interest Rate to the extent lawful.

         As provided in the Note Indenture, the Class A-5 Notes may be redeemed,
in whole but not in part, at the option of the Note Issuer on any Payment Date
at the Optional Redemption Price if, after giving effect to payments that would
otherwise be made on such Payment Date, the Outstanding Amount of the Notes has
been reduced to less than five percent of the initial principal balance thereof.
In addition, as provided in the Note Indenture, if the Seller is required to
repurchase the Transition Property pursuant to Section 5.01 of the Sale
Agreement, the Note Issuer will be required to redeem all outstanding Notes,
including the Class A-5 Notes, on or before the fifth Business Day following the
Repurchase Date (as defined in the Sale Agreement).

         As provided in the Note Indenture and subject to certain limitations
set forth therein, the transfer of this Class A-5 Note may be registered on the
Note Register upon surrender of this Class A-5 Note for registration of transfer
at the office or agency designated by the Note Issuer pursuant to the Note
Indenture, duly endorsed by, or accompanied by (a) a written instrument of
transfer in form satisfactory to the Note Trustee duly executed by the Holder
hereof or his attorney duly authorized in writing, with such signature
guaranteed by an institution which is a member of one of the following
recognized Signature Guaranty Programs: (i) The Securities Transfer Agent
Medallion Program (STAMP); (ii) The New York Stock Exchange Medallion


                                       6
<PAGE>   43
Program (MSP); (iii) The Stock Exchange Medallion Program (SEMP); or (iv) in
such other guarantee program acceptable to the Note Trustee, and (b) such other
documents as the Note Trustee may require, and thereupon one or more new Class
A-5 Notes of Minimum Denominations and in the same aggregate principal amount
will be issued to the designated transferee or transferees. No service charge
will be charged for any registration of transfer or exchange of this Class A-5
Note, but the transferor may be required to pay a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any such
registration of transfer or exchange, other than exchanges pursuant to Section
2.04 of the Note Indenture not involving any transfer.

         Each Noteholder, by acceptance of a Note, covenants and agrees that no
recourse may be taken, directly or indirectly, with respect to the obligations
of the Note Issuer or the Note Trustee on the Notes or under the Note Indenture
or any certificate or other writing delivered in connection therewith, against
(i) the Note Trustee in its individual capacity, (ii) any owner of a beneficial
interest in the Note Issuer or (iii) any partner, owner, beneficiary, agent,
officer, director or employee of the Note Trustee in its individual capacity,
any holder of a beneficial interest in the Note Issuer or the Note Trustee or of
any successor or assign of the Note Trustee in its individual capacity, except
as any such Person may have expressly agreed (it being understood that the Note
Trustee has no such obligations in its individual capacity).

         Prior to the due presentment for registration of transfer of this Class
A-5 Note, the Note Issuer, the Note Trustee and any agent of the Note Issuer or
the Note Trustee may treat the Person in whose name this Class A-5 Note is
registered (as of the day of determination) as the owner hereof for the purpose
of receiving payments of principal of and interest on this Class A-5 Note and
for all other purposes whatsoever, whether or not this Class A-5 Note be
overdue, and neither the Note Issuer, the Note Trustee nor any such agent shall
be affected by notice to the contrary.

         The Note Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Note Issuer and the rights of the Holders of the Notes under
the Note Indenture at any time by the Note Issuer with the consent of the
Holders of Notes representing a majority of the Outstanding Amount of all Notes
at the time Outstanding of each Class to be affected. The Note Indenture also
contains provisions permitting the Holders of Notes representing specified
percentages of the Outstanding Amount of the Notes, on behalf of the Holders of
all the Notes, to waive compliance by the Note Issuer with certain provisions of
the Note Indenture and certain past defaults under the Note Indenture and their
consequences. Any such consent or waiver by the Holder of this Class A-5 Note
(or any one of more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Class A-5 Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Class A-5
Note. The Note Indenture also permits the Note Trustee to amend or waive certain
terms and conditions set forth in the Note Indenture without the consent of
Holders of the Notes issued thereunder.

         The term "Note Issuer" as used in this Class A-5 Note includes any
successor to the Note Issuer under the Note Indenture.

         The Note Issuer is permitted by the Note Indenture, under certain
circumstances, to merge or consolidate, subject to the rights of the Note
Trustee and the Holders of Notes under the Note Indenture.

         The Class A-5 Notes are issuable only in registered form in
denominations as provided in the Note Indenture, subject to certain limitations
therein set forth.

         This Class A-5 Note and the Note Indenture shall be construed in
accordance with the laws of The Commonwealth of Massachusetts, without reference
to its conflict of law provisions, and the obligations, rights and remedies of
the parties hereunder and thereunder shall be determined in accordance with such
laws.

         No reference herein to the Note Indenture and no provision of this
Class A-5 Note or of the Note Indenture shall alter or impair the obligation of
the Note Issuer, which is absolute and unconditional, to pay the principal of
and interest on this Class A-5 Note at the times, place, and rate, and in the
coin or currency herein prescribed.

         The Holder of this Class A-5 Note by the acceptance hereof agrees that,
notwithstanding any provision of the Note Indenture to the contrary, the Holder
shall have no recourse against the Note Issuer, but shall look only to the
Collateral, with respect to any amounts due to the Holder under this Class A-5
Note.

in an Underlying Note (as defined below) of the corresponding class issued by
BEC Funding LLC, a Delaware limited liability company, and the proceeds thereof,
held by a trust or registered assigns, as more fully described herein.

         This Certificate does not represent an interest in or obligation of The
Commonwealth of Massachusetts, the Massachusetts Development Finance Agency or
the Massachusetts Health and Educational Facilities Authority (collectively, the
"Agencies"), any other governmental agency or instrumentality or Boston Edison
Company, a Massachusetts corporation ("Boston Edison"), or any of its
affiliates. None of the Certificate, the Underlying Note or the underlying

         Neither the full faith and credit nor the taxing power of The
Commonwealth of Massachusetts, either of the Agencies or any other governmental
agency or instrumentality is pledged to the payment of the principal of,
purchase price of, or interest on, this Certificate or the Underlying Note, or
to the payments in respect of the Transition Property, nor are The Commonwealth
of Massachusetts, either of the Agencies or any other governmental agency or

         THIS CERTIFIES THAT CEDE & CO., as nominee for The Depository Trust
Company, for value received, is the registered owner of a Principal Amount
(stated above) of nonassessable, fully-paid, fractional undivided beneficial
interest in the related Underlying Note and the proceeds thereof held by
Massachusetts RRB Special Purpose Trust BEC-1 (the "Trust") or registered
assigns. The Trust is created pursuant to, and this Certificate is issued under
and is subject to the terms, provisions and conditions of, a Declaration of
Trust dated as of July 28, 1999 by The Bank of New York (Delaware), as Delaware
trustee (the "Delaware Trustee"), and the Agencies, acting jointly as settlors
thereunder pursuant to Chapter 164 of the Massachusetts Acts of 1997 (the
"Statute"). This Certificate is issued under and is subject to the terms,
provisions, and conditions of, a Certificate Indenture dated as of July 29, 1999
(the "Certificate Indenture"), by and among the Delaware Trustee, The Bank of
New York, as certificate trustee (the "Certificate Trustee"), and the Trust, a
summary of certain of the pertinent provisions of which is set forth below. This
Certificate is one of the duly authorized class of Certificates designated as
"Massachusetts RRB Special Purpose Trust BEC-1 Rate Reduction Certificates,
Class A-1" (herein called the "Class A-1 Certificates"). The Class A-1
Certificates are one of a class of Certificates issued under the Certificate
Indenture (such Class A-1 Certificates, together with other Classes of
Certificates issued on the date hereof under the Certificate Indenture being
herein called the "Certificates"). The holder of this Certificate (the
"Holder"), by virtue of its acceptance hereof, assents and agrees to be bound by
the terms of the Certificate Indenture. This Class A-1 Certificate represents a
fractional undivided beneficial interest in the note of the corresponding class
(the "Underlying Note") issued by BEC Funding LLC, as Note Issuer, together with
the payments on and proceeds of the Underlying Note. The Underlying Note is
secured by a security interest in the property right created under the Statute,
pursuant to the order of the Massachusetts Department of Telecommunications and
Energy, DTE-98-118, issued on April 2, 1999, as further clarified by the Order
on the Massachusetts Development Finance Agency's and the Massachusetts Health
and Educational Facilities Authority's Motion for Clarification dated May 21,
1999 (collectively, the "Financing Order"), representing the irrevocable right
of Boston Edison or its assignee to receive a certain nonbypassable charge (as
adjusted from time to time) from certain retail customers of Boston Edison's
distribution system, together with certain related collateral, all as more fully
described in the Note Indenture.

         To the extent not otherwise defined herein, the capitalized terms used
have the meanings assigned to them in the Certificate Indenture.

         The aggregate principal amount of all Certificates of all Classes
issued under the Certificate Indenture equals the aggregate principal amount of
the Underlying Notes of all Classes, and all such Certificates are and will be
equally secured by the pledge and covenants made therein, except as otherwise
expressly provided or permitted in the Certificate Indenture.

         Subject to and in accordance with the terms of the Certificate
Indenture, there will be distributed on each March 15 and September 15 of each
year or, if any such day is not a Business Day, the next succeeding Business Day
(each, a "Distribution Date"), commencing on March 15, 2000 to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day immediately preceding the related Distribution Date or, if
Definitive Certificates are issued, the last day of the immediately preceding
calendar month (each, a "Record Date"), such Holder's fractional undivided
interest in the payments made on the Underlying Note due on the related Payment
Date, the receipt of which has been confirmed by the Certificate Trustee.
Subject to and in accordance with the terms of the Certificate Indenture, in the
event that a Special Payment on the Underlying Note is received by the
Certificate Trustee, from funds then available to the Certificate Trustee, there
will be distributed on the applicable Special Distribution Date, to the Person
in whose name this Certificate is registered on the Record Date preceding the
Special Distribution Date, as applicable, such Holder's fractional undivided
share of such amount. The Special Distribution Date will be determined as
provided in the Certificate Indenture. The Certificate Trustee will mail notice
of each Special Payment and the related Special Distribution Date to the Holder
as provided in the Certificate Indenture.

         Distributions on this Certificate will be made as provided in the
Certificate Indenture by the Certificate Trustee by wire transfer or check
mailed to the Holder of record in the Certificate Register without the
presentation or surrender of this Certificate or the making of any notation
hereon, except that with respect to Certificates registered on the Record Date
in the name of the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Except as otherwise provided in
the Certificate Indenture and notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Certificate Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office of the Paying Agent or the office or agency
maintained for that purpose by the Certificate Trustee in The City of New York.

         (a) Subject to and in accordance with the terms of the Certificate
Indenture, the Trust has represented and warranted under the Certificate
Indenture that the Trust constitutes a "special purpose trust" and a "financing
entity" under Section 1H(a) of the Statute, and that the Certificates constitute
"electric rate reduction bonds" under Section 1H(a) of the Statute and that the
Holders are entitled to the rights and benefits thereunder. Pursuant to Section
1H(b)(3) of the Statute, The Commonwealth of Massachusetts, has additionally
pledged and agreed with the Note Issuer, the Trust and the Holders (the
"Commonwealth Pledge") as follows:

                  (b) [T]he [C]ommonwealth [of Massachusetts] does hereby pledge
                  and agree with the owners of the transition property and
                  holders of electric rate reduction bonds that the
                  [C]ommonwealth [of Massachusetts] shall not (i) alter the
                  provisions of this chapter which make the transition charges
                  imposed by the financing order irrevocable and binding or (ii)
                  limit or alter the reimbursable transition costs amounts,
                  transition property, financing orders, and all rights
                  thereunder until the electric rate reduction bonds, together
                  with the interest thereon, are fully met and discharged.

                                       3
<PAGE>   4
         In addition, the Trust has pledged and agreed with the Note Issuer and
the Holders of the Certificates that it will not act in a manner inconsistent
with the Commonwealth Pledge and will not take any action that would impair any
rights of the Note Issuer or the Holders in the Notes, the Transition Property
or the Certificates.

         Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon shall have been

         IS WRONGFUL INASMUCH THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
         INTEREST HEREIN.

         This Certificate evidences a fractional undivided beneficial interest
in an Underlying Note (as defined below) of the corresponding class issued by
BEC Funding LLC, a Delaware limited liability company, and the proceeds thereof,
held by a trust or registered assigns, as more fully described herein.

         This Certificate does not represent an interest in or obligation of The
Commonwealth of Massachusetts, the Massachusetts Development Finance Agency or
the Massachusetts Health and Educational Facilities Authority (collectively, the
"Agencies"), any other governmental agency or instrumentality or Boston Edison
Company, a Massachusetts corporation ("Boston Edison"), or any of its
affiliates. None of the Certificate, the Underlying Note or the underlying
Transition Property (as defined in the Certificate Indenture) will be guaranteed
or insured by The Commonwealth of Massachusetts, either of the Agencies, the
Trust (as defined below) or any other governmental agency or instrumentality or
by Boston Edison or its affiliates.
<PAGE>   9
         Neither the full faith and credit nor the taxing power of The
Commonwealth of Massachusetts, either of the Agencies or any other governmental
agency or instrumentality is pledged to the payment of the principal of,
purchase price of, or interest on, this Certificate or the Underlying Note, or
to the payments in respect of the Transition Property, nor are The Commonwealth
of Massachusetts, either of the Agencies or any other governmental agency or
instrumentality in any manner obligated to make any appropriation for the
payment thereof.

         THIS CERTIFIES THAT CEDE & CO., as nominee for The Depository Trust
Company, for value received, is the registered owner of a Principal Amount
(stated above) of nonassessable, fully-paid, fractional undivided beneficial
interest in the related Underlying Note and the proceeds thereof held by
Massachusetts RRB Special Purpose Trust BEC-1 (the "Trust") or registered
assigns. The Trust is created pursuant to, and this Certificate is issued under
and is subject to the terms, provisions and conditions of, a Declaration of
Trust dated as of July 28, 1999 by The Bank of New York (Delaware), as Delaware
trustee (the "Delaware Trustee"), and the Agencies, acting jointly as settlors
thereunder pursuant to Chapter 164 of the Massachusetts Acts of 1997 (the
"Statute"). This Certificate is issued under and is subject to the terms,
provisions, and conditions of, a Certificate Indenture dated as of July 29, 1999
(the "Certificate Indenture"), by and among the Delaware Trustee, The Bank of
New York, as certificate trustee (the "Certificate Trustee"), and the Trust, a
summary of certain of the pertinent provisions of which is set forth below. This
Certificate is one of the duly authorized class of Certificates designated as
"Massachusetts RRB Special Purpose Trust BEC-1 Rate Reduction Certificates,
Class A-2" (herein called the "Class A-2 Certificates"). The Class A-2
Certificates are one of a class of Certificates issued under the Certificate
Indenture (such Class A-2 Certificates, together with other Classes of
Certificates issued on the date hereof under the Certificate Indenture being
herein called the "Certificates"). The holder of this Certificate (the
"Holder"), by virtue of its acceptance hereof, assents and agrees to be bound by
the terms of the Certificate Indenture. This Class A-2 Certificate represents a
fractional undivided beneficial interest in the note of the corresponding class
(the "Underlying Note") issued by BEC Funding LLC, as Note Issuer, together with
the payments on and proceeds of the Underlying Note. The Underlying Note is
secured by a security interest in the property right created under the Statute,
pursuant to the order of the Massachusetts Department of Telecommunications and
Energy, DTE-98-118, issued on April 2, 1999, as further clarified by the Order
on the Massachusetts Development Finance Agency's and the Massachusetts Health
and Educational Facilities Authority's Motion for Clarification dated May 21,
1999 (collectively, the "Financing Order"), representing the irrevocable right
of Boston Edison or its assignee to receive a certain nonbypassable charge (as
adjusted from time to time) from certain retail customers of Boston Edison's
distribution system, together with certain related collateral, all as more fully
described in the Note Indenture.

         To the extent not otherwise defined herein, the capitalized terms used
have the meanings assigned to them in the Certificate Indenture.

         The aggregate principal amount of all Certificates of all Classes
issued under the Certificate Indenture equals the aggregate principal amount of
the Underlying Notes of all Classes, and all such Certificates are and will be
equally secured by the pledge and covenants made therein, except as otherwise
expressly provided or permitted in the Certificate Indenture.

         Subject to and in accordance with the terms of the Certificate
Indenture, there will be distributed on each March 15 and September 15 of each
year or, if any such day is not a Business Day, the next succeeding Business Day
(each, a "Distribution Date"), commencing on March 15, 2000 to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day immediately preceding the related Distribution Date or, if
Definitive Certificates are issued, the last day of the immediately preceding
calendar month (each, a "Record Date"), such Holder's fractional undivided
interest in the payments made on the Underlying Note due on the related Payment
Date, the receipt of which has been confirmed by the Certificate Trustee.
Subject to and in accordance with the terms of the Certificate Indenture, in the
event that a Special Payment on the Underlying Note is received by the
Certificate Trustee, from funds then available to the Certificate Trustee, there
will be distributed on the applicable Special Distribution Date, to the Person
in whose name this Certificate is registered on the Record Date preceding the
Special Distribution Date, as applicable, such Holder's fractional undivided
share of such amount. The Special Distribution Date will be determined as
provided in the Certificate Indenture. The Certificate Trustee will mail notice
of each Special Payment and the related Special Distribution Date to the Holder
as provided in the Certificate Indenture.

         Distributions on this Certificate will be made as provided in the
Certificate Indenture by the Certificate Trustee by wire transfer or check
mailed to the Holder of record in the Certificate Register without the
presentation or surrender of this Certificate or the making of any notation
hereon, except that with respect to Certificates registered on the Record Date
in the name of the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Except as otherwise provided in
the Certificate Indenture and notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Certificate Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office of the Paying Agent or the office or agency
maintained for that purpose by the Certificate Trustee in The City of New York.

         (c) Subject to and in accordance with the terms of the Certificate
Indenture, the Trust has represented and warranted under the Certificate
Indenture that the Trust constitutes a "special purpose trust" and a "financing
entity" under Section 1H(a) of the Statute, and that the Certificates constitute
"electric rate reduction bonds" under Section 1H(a) of the Statute and that the
Holders are entitled to the rights and benefits thereunder. Pursuant to Section
1H(b)(3) of the Statute, The Commonwealth of Massachusetts, has additionally
pledged and agreed with the Note Issuer, the Trust and the Holders (the
"Commonwealth Pledge") as follows:

                  (d) [T]he [C]ommonwealth [of Massachusetts] does hereby pledge
                  and agree with the owners of the transition property and
                  holders of electric rate reduction bonds that the
                  [C]ommonwealth [of Massachusetts] shall not (i) alter the
                  provisions of this chapter which make the transition charges
                  imposed by the financing order irrevocable and binding or (ii)
                  limit or alter the reimbursable transition costs amounts,
                  transition property, financing orders, and all rights
                  thereunder until the electric rate reduction bonds, together
                  with the interest thereon, are fully met and discharged.

                                       3
<PAGE>   11
         In addition, the Trust has pledged and agreed with the Note Issuer and
the Holders of the Certificates that it will not act in a manner inconsistent
with the Commonwealth Pledge and will not take any action that would impair any
rights of the Note Issuer or the Holders in the Notes, the Transition Property
or the Certificates.

         Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon shall have been
executed by an authorized officer of the Certificate Trustee by manual
signature, this Certificate shall not be entitled to any benefit under the
Certificate Indenture or any other Basic Document or be valid for any purpose.

         THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE DOMESTIC LAW OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF
LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES
HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAW.

         Any reduction in the principal amount of any Certificate effected by
any distribution in respect of principal thereof shall be binding upon all
Holders of such Certificate and of any Certificate issued upon the registration
of transfer thereof or in exchange thereof or in lieu thereof, whether or not
noted thereon.

                  It is expressly agreed and understood by the parties hereto
that (a) this Certificate is executed by The Bank of New York (Delaware) and
authenticated and delivered by The Bank of New York, not individually or
personally but solely as Delaware Trustee and Certificate Trustee, respectively,
on behalf of the Trust in the exercise of the powers and authority conferred and

by the Delaware Trustee and Certificate Trustee on behalf of the Trust are made
and intended not as personal representations, undertakings and agreements of
either trustee, but are made and intended for the purpose of binding only the
Trust, (c) nothing herein contained shall be construed as creating any liability
on The Bank of New York (Delaware) or The Bank of New York, individually or
personally, to perform any covenant either expressed or implied herein, except
in their capacity as Delaware Trustee and Certificate Trustee, respectively, all
such liability being expressly waived by all Persons, and (d) under no
circumstances shall The Bank of New York (Delaware) or The Bank of New York be
personally liable for the payment of any indebtedness or expenses of the Trust,

         THIS CERTIFIES THAT CEDE & CO., as nominee for The Depository Trust

(stated above) of nonassessable, fully-paid, fractional undivided beneficial
interest in the related Underlying Note and the proceeds thereof held by
Massachusetts RRB Special Purpose Trust BEC-1 (the "Trust") or registered
assigns. The Trust is created pursuant to, and this Certificate is issued under
and is subject to the terms, provisions and conditions of, a Declaration of
Trust dated as of July 28, 1999 by The Bank of New York (Delaware), as Delaware
trustee (the "Delaware Trustee"), and the Agencies, acting jointly as settlors
thereunder pursuant to Chapter 164 of the Massachusetts Acts of 1997 (the
"Statute"). This Certificate is issued under and is subject to the terms,
provisions, and conditions of, a Certificate Indenture dated as of July 29, 1999
(the "Certificate Indenture"), by and among the Delaware Trustee, The Bank of
New York, as certificate trustee (the "Certificate Trustee"), and the Trust, a
summary of certain of the pertinent provisions of which is set forth below. This
Certificate is one of the duly authorized class of Certificates designated as
"Massachusetts RRB Special Purpose Trust BEC-1 Rate Reduction Certificates,
Class A-3" (herein called the "Class A-3 Certificates"). The Class A-3
Certificates are one of a class of Certificates issued under the Certificate
Indenture (such Class A-3 Certificates, together with other Classes of
Certificates issued on the date hereof under the Certificate Indenture being
herein called the "Certificates"). The holder of this Certificate (the
"Holder"), by virtue of its acceptance hereof, assents and agrees to be bound by
the terms of the Certificate Indenture. This Class A-3 Certificate represents a
fractional undivided beneficial interest in the note of the corresponding class
(the "Underlying Note") issued by BEC Funding LLC, as Note Issuer, together with
the payments on and proceeds of the Underlying Note. The Underlying Note is
secured by a security interest in the property right created under the Statute,
pursuant to the order of the Massachusetts Department of Telecommunications and
Energy, DTE-98-118, issued on April 2, 1999, as further clarified by the Order
on the Massachusetts Development Finance Agency's and the Massachusetts Health
and Educational Facilities Authority's Motion for Clarification dated May 21,
1999 (collectively, the "Financing Order"), representing the irrevocable right
of Boston Edison or its assignee to receive a certain nonbypassable charge (as
adjusted from time to time) from certain retail customers of Boston Edison's
distribution system, together with certain related collateral, all as more fully
described in the Note Indenture.

         To the extent not otherwise defined herein, the capitalized terms used
have the meanings assigned to them in the Certificate Indenture.

issued under the Certificate Indenture equals the aggregate principal amount of
the Underlying Notes of all Classes, and all such Certificates are and will be
equally secured by the pledge and covenants made therein, except as otherwise
expressly provided or permitted in the Certificate Indenture.

         Subject to and in accordance with the terms of the Certificate
Indenture, there will be distributed on each March 15 and September 15 of each
year or, if any such day is not a Business Day, the next succeeding Business Day
(each, a "Distribution Date"), commencing on March 15, 2000 to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day immediately preceding the related Distribution Date or, if
Definitive Certificates are issued, the last day of the immediately preceding
calendar month (each, a "Record Date"), such Holder's fractional undivided
interest in the payments made on the Underlying Note due on the related Payment
Date, the receipt of which has been confirmed by the Certificate Trustee.
Subject to and in accordance with the terms of the Certificate Indenture, in the
event that a Special Payment on the Underlying Note is received by the
Certificate Trustee, from funds then available to the Certificate Trustee, there
will be distributed on the applicable Special Distribution Date, to the Person
in whose name this Certificate is registered on the Record Date preceding the

hereon, except that with respect to Certificates registered on the Record Date
in the name of the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Except as otherwise provided in
the Certificate Indenture and notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Certificate Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office of the Paying Agent or the office or agency
maintained for that purpose by the Certificate Trustee in The City of New York.

         (e) Subject to and in accordance with the terms of the Certificate
Indenture, the Trust has represented and warranted under the Certificate
Indenture that the Trust constitutes a "special purpose trust" and a "financing
entity" under Section 1H(a) of the Statute, and that the Certificates constitute
"electric rate reduction bonds" under Section 1H(a) of the Statute and that the
Holders are entitled to the rights and benefits thereunder. Pursuant to Section
1H(b)(3) of the Statute, The Commonwealth of Massachusetts, has additionally
pledged and agreed with the Note Issuer, the Trust and the Holders (the
"Commonwealth Pledge") as follows:

                  (f) [T]he [C]ommonwealth [of Massachusetts] does hereby pledge
                  and agree with the owners of the transition property and
                  holders of electric rate reduction bonds that the
                  [C]ommonwealth [of Massachusetts] shall not (i) alter the
                  provisions of this chapter which make the transition charges
                  imposed by the financing order irrevocable and binding or (ii)
                  limit or alter the reimbursable transition costs amounts,
                  transition property, financing orders, and all rights
                  thereunder until the electric rate reduction bonds, together
                  with the interest thereon, are fully met and discharged.

<PAGE>   18
         In addition, the Trust has pledged and agreed with the Note Issuer and
the Holders of the Certificates that it will not act in a manner inconsistent
with the Commonwealth Pledge and will not take any action that would impair any
rights of the Note Issuer or the Holders in the Notes, the Transition Property
or the Certificates.

         Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

THE DOMESTIC LAW OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF
LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES
HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAW.

any distribution in respect of principal thereof shall be binding upon all
Holders of such Certificate and of any Certificate issued upon the registration
of transfer thereof or in exchange thereof or in lieu thereof, whether or not
noted thereon.

such liability being expressly waived by all Persons, and (d) under no

New York, as certificate trustee (the "Certificate Trustee"), and the Trust, a
summary of certain of the pertinent provisions of which is set forth below. This
Certificate is one of the duly authorized class of Certificates designated as
"Massachusetts RRB Special Purpose Trust BEC-1 Rate Reduction Certificates,
Class A-4" (herein called the "Class A-4 Certificates"). The Class A-4
Certificates are one of a class of Certificates issued under the Certificate
Indenture (such Class A-4 Certificates, together with other Classes of
Certificates issued on the date hereof under the Certificate Indenture being
herein called the "Certificates"). The holder of this Certificate (the
"Holder"), by virtue of its acceptance hereof, assents and agrees to be bound by
the terms of the Certificate Indenture. This Class A-4 Certificate represents a
fractional undivided beneficial interest in the note of the corresponding class
(the "Underlying Note") issued by BEC Funding LLC, as Note Issuer, together with
the payments on and proceeds of the Underlying Note. The Underlying Note is
secured by a security interest in the property right created under the Statute,
pursuant to the order of the Massachusetts Department of Telecommunications and
Energy, DTE-98-118, issued on April 2, 1999, as further clarified by the Order
on the Massachusetts Development Finance Agency's and the Massachusetts Health
and Educational Facilities Authority's Motion for Clarification dated May 21,
1999 (collectively, the "Financing Order"), representing the irrevocable right
of Boston Edison or its assignee to receive a certain nonbypassable charge (as
adjusted from time to time) from certain retail customers of Boston Edison's
distribution system, together with certain related collateral, all as more fully
described in the Note Indenture.

         To the extent not otherwise defined herein, the capitalized terms used
have the meanings assigned to them in the Certificate Indenture.

         The aggregate principal amount of all Certificates of all Classes
issued under the Certificate Indenture equals the aggregate principal amount of
the Underlying Notes of all Classes, and all such Certificates are and will be
equally secured by the pledge and covenants made therein, except as otherwise
expressly provided or permitted in the Certificate Indenture.

         Subject to and in accordance with the terms of the Certificate
Indenture, there will be distributed on each March 15 and September 15 of each
year or, if any such day is not a Business Day, the next succeeding Business Day
(each, a "Distribution Date"), commencing on March 15, 2000 to the Person in
whose name this Certificate is registered at the close of business on the last

Definitive Certificates are issued, the last day of the immediately preceding

interest in the payments made on the Underlying Note due on the related Payment
Date, the receipt of which has been confirmed by the Certificate Trustee.
Subject to and in accordance with the terms of the Certificate Indenture, in the
event that a Special Payment on the Underlying Note is received by the
Certificate Trustee, from funds then available to the Certificate Trustee, there
will be distributed on the applicable Special Distribution Date, to the Person
in whose name this Certificate is registered on the Record Date preceding the
Special Distribution Date, as applicable, such Holder's fractional undivided
share of such amount. The Special Distribution Date will be determined as
provided in the Certificate Indenture. The Certificate Trustee will mail notice
of each Special Payment and the related Special Distribution Date to the Holder
as provided in the Certificate Indenture.

         Distributions on this Certificate will be made as provided in the
Certificate Indenture by the Certificate Trustee by wire transfer or check
mailed to the Holder of record in the Certificate Register without the
presentation or surrender of this Certificate or the making of any notation
hereon, except that with respect to Certificates registered on the Record Date
in the name of the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Except as otherwise provided in
the Certificate Indenture and notwithstanding the above, the final distribution
on this Certificate will be made after due notice by the Certificate Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office of the Paying Agent or the office or agency
maintained for that purpose by the Certificate Trustee in The City of New York.

Indenture, the Trust has represented and warranted under the Certificate

specifically set forth on the face hereof and in the Certificate Indenture. All

therein provided, the amendment thereof and the modification of the rights of
the Holders under the Certificate Indenture at any time by the Trust and the
Certificate Trustee with the consent of the Holders holding Certificates
representing not less than a majority of the aggregate Outstanding Amount of
Certificates of each affected Class issued by the Trust. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Certificate
Indenture also permits the amendment thereof, in certain limited circumstances,
without the consent of the Holders of any of the Certificates.

                  As provided in the Certificate Indenture and subject to
certain limitations therein set forth, the transfer of this Certificate is

successor Certificate Registrar, in the Borough of Manhattan, The City of New

satisfactory to the Certificate Trustee and the Certificate Registrar duly
executed by the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of authorized denominations
evidencing the same aggregate fractional undivided beneficial interest in the
Underlying Note will be issued to the designated transferee or transferees.

                  The Certificates are issuable only as registered Certificates
without coupons in Minimum Denominations of $1,000 Original Principal Amount and
integral multiples thereof. As provided in the Certificate Indenture and subject
to certain limitations therein set forth, Certificates are exchangeable for new

fractional undivided beneficial interest in the Underlying Notes, as requested
by the Holder surrendering the same.

setting over and conveyance is hereby expressly stated to be a sale and,
pursuant to Section 1H(f)(1) of Chapter 164 of the Massachusetts General Laws,
shall be treated as an absolute transfer of all of the Seller's right, title and
interest in (as in a true sale), and not as a pledge or other financing of, the
Transition Property. If such sale, transfer, assignment, setting over and
conveyance is held by any court of competent jurisdiction not to be a true sale
as provided in Section 1H(f)(1) of Chapter 164 of the Massachusetts General
Laws, then such sale, transfer, assignment, setting over and conveyance shall be
treated as the creation of a security interest in the Transition Property and,
without prejudice to its position that it has absolutely transferred all of its
rights in the Transition Property to the Note Issuer, the Seller hereby grants a
security interest in the Transition Property to the Note Issuer (the "Back-Up
Security Interest").

              ARTICLE III. REPRESENTATIONS AND WARRANTIES OF SELLER

         Subject to Section 3.09 hereof, the Seller makes the following
representations and warranties, as of the Closing Date, on which the Note Issuer
has relied in acquiring the Transition Property.

requisite corporate power and authority to own the Transition Property.

         Section 3.02. Due Qualification. The Seller is duly qualified to do
business as a foreign corporation in good standing, and has obtained all
necessary licenses and approvals, in all jurisdictions in which the ownership or
lease of property or the conduct of its business shall require such
qualifications, licenses or approvals (except where the failure to so qualify or
obtain such licenses and approvals would not be reasonably likely to have a
material adverse effect on the Seller's business, operations, assets, revenues
or properties).

         Section 3.03. Power and Authority. The Seller has the requisite
corporate power and authority to execute and deliver this Agreement and to carry
out its terms; and the execution, delivery and performance of this Agreement
have been duly authorized by all necessary corporate action on the part of the
Seller.

         Section 3.04. Binding Obligation. This Agreement constitutes a legal,
valid and binding obligation of the Seller enforceable against it in accordance
with its terms, subject to applicable insolvency, reorganization, moratorium,
fraudulent transfer and other laws relating to or affecting creditors' or
secured parties' rights generally from time to time in effect and to general
principles of equity (including concepts of materiality, reasonableness, good
faith and fair dealing), regardless of whether considered in a proceeding in
equity or at law.

         Section 3.05. No Violation. The consummation of the transactions
contemplated by this Agreement and the fulfillment of the terms hereof do not:
(i) conflict with or result in any breach of any of the terms and provisions of,
nor constitute (with or without notice or lapse of time) a default under, the
articles of organization or by-laws of the Seller, or any material indenture,
agreement or other instrument to which the Seller is a party or by which it is
bound; (ii) result in the creation or imposition of any Lien upon any of the
Seller's properties pursuant to the terms of any such indenture, agreement or
other instrument (other than any Lien that may be granted under the Basic
Documents or any Lien created pursuant to Section 1H(e) of Chapter 164 of the
Massachusetts General Laws); or (iii) violate any existing law or any existing
order, rule or regulation applicable to the Seller of any court or of any
federal or state regulatory body, administrative agency or other governmental
instrumentality having jurisdiction over the Seller or its properties.

         Section 3.06. No Proceedings. There are no proceedings pending and, to
the Seller's knowledge, there are no proceedings threatened and, to the Seller's
knowledge, there are no investigations pending or threatened, before any court,
federal or state regulatory body, administrative agency or other governmental
instrumentality having jurisdiction over the Seller or its properties involving
or relating to the Seller or the Note Issuer or, to the Seller's knowledge, any
other Person: (i) asserting the invalidity of this Agreement, any of the other
Basic Documents, the Notes or the Certificates, (ii) seeking to prevent the
issuance of the Notes or the Certificates or the consummation of any of the
transactions contemplated by this Agreement or any of the other Basic Documents,
(iii) seeking any determination or ruling that might materially and adversely
affect the performance by the Seller of its obligations under, or the validity
or enforceability of, this Agreement, any of the other Basic Documents, the
Notes or the Certificates or (iv) seeking to adversely affect the federal or
state income tax classification of the Notes or the Certificates as debt.

         Section 3.07. Approvals. No approval, authorization, consent, order or
other action of, or filing with, any court, federal or state regulatory body,
administrative agency or other governmental instrumentality is required in
connection with the execution and delivery by the Seller of this Agreement, the
performance by the Seller of the transactions contemplated hereby or the
fulfillment by the Seller of the terms hereof, except those that have been
obtained or made and those that the Seller, in its capacity as Servicer under
the Servicing Agreement, is required to make in the future pursuant to the
Servicing Agreement.

         Section 3.08. The Transition Property.

         (a) Title. It is the intention of the parties hereto that the transfer
and assignment herein contemplated constitute a sale of the Transition Property
from the Seller to the Note Issuer and that no interest in, or title to, the
Transition Property shall be part of the Seller's estate in the event of the
filing of a bankruptcy petition by or against the Seller under any bankruptcy
law. No portion of the Transition Property has been sold, transferred, assigned
or pledged by the Seller to any Person other than the Note Issuer. On the
Closing Date, immediately upon the sale hereunder, the Seller has transferred,
sold and conveyed the Transition Property to the Note Issuer, free and clear of
all Liens, except for any Lien created pursuant to Section 1H(e) of Chapter 164
of the Massachusetts General Laws and any Lien that may be granted under the
Basic Documents, and pursuant to Section 1H(f)(1) of Chapter 164 of the
Massachusetts General Laws such transfer shall be treated as an absolute
transfer of all of the Seller's right, title and interest (as in a true sale),
and not as a pledge or other financing of, the Transition Property.

         (b) Transfer Filings. On the Closing Date, immediately upon the sale
hereunder, the Transition Property has been validly transferred and sold to the
Note Issuer, the Note Issuer shall own all such Transition Property free and
clear of all Liens (except for any Lien created pursuant to Section 1H(e) of
Chapter 164 of the Massachusetts General Laws and any Lien that may be granted
under the Basic Documents) and all filings to be made by the Seller (including
filings with the DTE under the Statute) necessary in any jurisdiction to give
the Note Issuer an ownership interest (subject to any Lien created pursuant to
Section 1H(e) of Chapter 164 of the Massachusetts General Laws and any Lien that
may be granted under the Basic Documents) in the Transition Property have been
made. No further action is required to maintain such ownership interest (subject
to any Lien created pursuant to Section 1H(e) of Chapter 164 of the
Massachusetts General Laws and any Lien that may be granted under the Basic
Documents). Filings have also been made to the extent required by Massachusetts
General Laws Chapter 106, Sections 9-403(2)-(3), 9-306, 9-402(7) and 9-103 to
perfect the Back-Up Security Interest granted by the Seller to the Note Issuer
(subject to any Lien created pursuant to Section 1H(e) of Chapter 164 of the
Massachusetts General Laws and any Lien that may be granted under the Basic
Documents).

         (c) Financing Order and Issuance Advice Letter; Other Approvals. On the
Closing Date, under the laws of The Commonwealth of Massachusetts and the United
States in effect on the Closing Date, (i) the Financing Order pursuant to which
the Transition Property has been created is in full force and effect; (ii) the
Certificateholders are entitled to the protections of the Statute and,
accordingly, the Financing Order is not revocable by the DTE; (iii) The
Commonwealth of Massachusetts may not alter the provisions of the Statute that
make the RTC Charge irrevocable and binding, limit or alter the Transition
Property or the Financing Order, and all rights thereunder, in a manner that
would substantially impair the rights of the Certificateholders, absent a
demonstration by The Commonwealth of Massachusetts that an impairment is
narrowly-tailored and is necessary to advance an important public interest, such
as a "great public calamity" until the Certificates, together with interest
thereon, are fully met and

                                       -8-
<PAGE>   12
discharged; (iv) the DTE may not, either by rescinding, altering or amending the
Financing Order, in any way reduce or impair the value of the Transition
Property either directly or indirectly by taking reimbursable transition costs
amounts into account when setting other rates for the Seller, in a manner that
would substantially impair the rights of Certificateholders, absent a
demonstration by The Commonwealth of Massachusetts that an impairment is
narrowly-tailored and is necessary to advance an important public interest,
such as a "great public calamity", until the Certificates, together with
interest thereon, are fully met and discharged; (v) the process by which the
Financing Order was adopted and approved, and the Financing Order and Issuance
Advice Letter themselves, comply with all applicable laws, rules and
regulations; (vi) the Issuance Advice Letter has been filed in accordance with
the Financing Order; and (vii) no other approval, authorization, consent, order
or other action of, or filing with, any court, Federal or state regulatory body,
administrative agency or other governmental instrumentality is required in
connection with the creation or sale of the Transition Property, except those
that have been obtained or made.

         (d) Assumptions. On the Closing Date, based upon the information
available to the Seller on the Closing Date, the assumptions used in calculating
the initial RTC Charge are reasonable and are made in good faith.
Notwithstanding the foregoing, the Seller makes no representation or warranty
that the assumptions used in calculating such RTC Charge will in fact be
realized.

         (e) Creation of Transition Property. Upon the effectiveness of the
Financing Order and the Issuance Advice Letter: (i) all of the Transition
Property constitutes an existing property right; (ii) the Transition Property
includes the right, title and interest in and to all revenues, collections,
claims, payments, money, or proceeds of or arising from the RTC Charge, as
adjusted from time to time pursuant to the Financing Order, and all rights to
obtain adjustments to the RTC Charge pursuant to the Financing Order; and (iii)
the owner of the Transition Property is legally entitled to collect payments in
respect of the RTC Charge in the aggregate sufficient to pay the interest on and
principal of the Notes, to pay the fees and expenses of servicing the Notes and
the Certificates, to replenish the Capital Subaccount to the Required Capital
Level and to fund the Overcollateralization Subaccount to the Required
Overcollateralization Level until the Notes and the Certificates are paid in
full. Notwithstanding the foregoing, the Seller makes no representation or
warranty that any amounts actually collected in respect of the RTC Charge will
in fact be sufficient to meet payment obligations with respect to the Notes and
the Certificates.

         (f) Prospectus. As of the date hereof, the information describing the
Seller in "The Seller and Servicer" section of the prospectus dated July 26,
1999 offering the Notes and the Certificates is correct in all material
respects.

         Section 3.09. Limitations on Representations and Warranties. Without
prejudice to any of the other rights of the parties, the Seller will not be in
breach of any representation or warranty as a result of a change in law by means
of a legislative enactment, constitutional amendment or

                                       -9-
<PAGE>   13
voter initiative. Notwithstanding anything to the contrary in this Agreement,
the Seller makes no representation or warranty that any amounts actually
collected in respect of the RTC Charge will in fact be sufficient to meet
payment obligations with respect to the Notes and the Certificates or that the
assumptions used in calculating the RTC Charge will in fact be realized nor
shall the Seller be obligated to reduce, or accept a reduction of, any rates or
charges to which it would otherwise be entitled in respect of services rendered
or to be rendered to Customers in order to permit the payment of the RTC Charge.

                       ARTICLE IV. COVENANTS OF THE SELLER

         Section 4.01. Corporate Existence. So long as any of the Notes are
outstanding, the Seller (a) will keep in full force and effect its existence,
rights and franchises as a corporation under the laws of the jurisdiction of its
organization and (b) will obtain and preserve its qualification to do business,
in each case to the extent that in each such jurisdiction such existence or
qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the other Basic Documents to which the Seller
is a party and each other instrument or agreement necessary or appropriate to
the proper administration of this Agreement and the transactions contemplated
hereby.

         Section 4.02. No Liens. Except for the conveyances hereunder or any
Lien under Section 1H(e) of Chapter 164 of the Massachusetts General Laws or for
the benefit of the Note Issuer, the Seller will not sell, pledge, assign or
transfer, or grant, create, or incur any Lien on, any of the Transition
Property, or any interest therein, and the Seller shall defend the right, title
and interest of the Note Issuer and the Note Trustee in, to and under the
Transition Property against all claims of third parties claiming through or
under the Seller. Boston Edison Company, in its capacity as Seller, will not at
any time assert any Lien against, or with respect to, any of the Transition
Property.

         Section 4.03. Delivery of Collections. If the Seller receives any
payments in respect of the RTC Charge or the proceeds thereof when it is not

received by it in respect thereof as soon as practicable after receipt thereof
by it.

         Section 4.04. Notice of Liens. The Seller shall notify the Note Issuer
and the Note Trustee promptly after becoming aware of any Lien on any of the
Transition Property, other than the conveyances hereunder, any Lien under the
Basic Documents or any Lien under Section 1H(e) of Chapter 164 of the
Massachusetts General Laws or for the benefit of the Note Issuer.

         Section 4.05. Compliance with Law. The Seller hereby agrees to comply
with its organizational and governing documents and all laws, treaties, rules,
regulations and determinations of any governmental instrumentality applicable to
it, except to the extent that failure to so comply would not adversely affect
the Note Issuer's or the Note Trustee's interests in the Transition Property or
under any of the other Basic Documents to which the Seller is party or

                                      -10-
<PAGE>   14
the Seller's performance of its obligations hereunder or under any of the other
Basic Documents to which it is party.

         Section 4.06. Covenants Related to Notes and Transition Property.

         (a) So long as any of the Notes are outstanding, the Seller shall treat
the Notes as debt of the Note Issuer and not of the Seller, except for financial
accounting or tax reporting purposes.

         (b) So long as any of the Notes are outstanding, the Seller shall
indicate in its financial statements that it is not the owner of the Transition
Property.

         (c) So long as any of the Notes or Certificates are outstanding, the
Seller shall not own or purchase any Notes or Certificates.

         (d) The Seller agrees that, upon the sale by the Seller of the
Transition Property to the Note Issuer pursuant to this Agreement, (i) to the
fullest extent permitted by law, including applicable DTE Regulations, the Note
Issuer shall have all of the rights originally held by the Seller with respect
to the Transition Property, including the right (subject to the terms of the
Servicing Agreement) to exercise any and all rights and remedies to collect any
amounts payable by any Customer in respect of the Transition Property,
notwithstanding any objection or direction to the contrary by the Seller and
(ii) any payment by any Customer to the Note Issuer shall discharge such
Customer's obligations in respect of the Transition Property to the extent of
such payment, notwithstanding any objection or direction to the contrary by the
Seller.

         (e) So long as any of the Notes are outstanding, (i) the Seller shall
not make any statement or reference in respect of the Transition Property that
is inconsistent with the ownership interest of the Note Issuer (other than for
financial accounting or tax reporting purposes), and (ii) the Seller shall not
take any action in respect of the Transition Property except solely in its
capacity as the Servicer thereof pursuant to the Servicing Agreement or as
otherwise contemplated by the Basic Documents.

         Section 4.07. Protection of Title. The Seller shall execute and file
such filings, including filings with the DTE pursuant to the Statute and Uniform
Commercial Code continuation statements, and cause to be executed and filed such
filings, all in such manner and in such places as may be required by law fully
to preserve, maintain and protect the ownership interest of the Note Issuer in
the Transition Property, including all filings required under the Statute
relating to the transfer of the ownership interest in the Transition Property by
the Seller to the Note Issuer and the continued perfection of such ownership
interest. The Seller shall deliver (or cause to be delivered) to the Note Issuer
file-stamped copies of, or filing receipts for, any document filed as provided
above, as soon as available following such filing. The Seller shall institute
any action or proceeding necessary to compel performance by the DTE or The
Commonwealth of Massachusetts of any of their obligations or duties under the
Statute or the Financing Order, and the Seller agrees to take such legal or
administrative actions, including

                                      -11-
<PAGE>   15
defending against or instituting and pursuing legal actions and appearing or
testifying at hearings or similar proceedings, as may be reasonably necessary to
protect the Note Issuer, the Noteholders, the Certificateholders and the
Agencies from claims, state actions or other actions or proceedings of third
parties which, if successfully pursued, would result in a breach of any
representation set forth in Article III. The costs of any such actions or
proceedings shall be payable from RTC Charge Collections as an Operating Expense
in accordance with the priorities set forth in Section 8.02(d) of the Note
Indenture. The Seller's obligations pursuant to this Section 4.07 shall survive
and continue notwithstanding the fact that the payment of Operating Expenses
pursuant to Section 8.02(d) of the Note Indenture may be delayed (it being
understood that the Seller may be required to advance its own funds to satisfy
its obligations hereunder).

         Section 4.08. Nonpetition Covenants. Notwithstanding any prior
termination of this Agreement or the Note Indenture, but subject to the DTE's
right to order the sequestration and payment of revenues arising with respect to
the Transition Property notwithstanding any bankruptcy, reorganization or other
insolvency proceedings with respect to the Seller pursuant to Section 1H(d)(5)
of the Statute, the Seller shall not, prior to the date which is one year and
one day after the termination of the Note Indenture, petition or otherwise
invoke or cause the Note Issuer to invoke the process of any court or government
authority for the purpose of commencing or sustaining a case against the Note
Issuer under any Federal or state bankruptcy, insolvency or similar law,
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or
other similar official of the Note Issuer or any substantial part of the
property of the Note Issuer, or ordering the winding up or liquidation of the
affairs of the Note Issuer.

         Section 4.09. Taxes. So long as any of the Notes are outstanding, the
Seller shall, and shall cause each of its subsidiaries to, pay all material
taxes, assessments and governmental charges imposed upon it or any of its
properties or assets or with respect to any of its franchises, business, income
or property before any penalty accrues thereon if the failure to pay any such
taxes, assessments and governmental charges would, after any applicable grace
periods, notices or other similar requirements, result in a lien on the
Transition Property; provided that no such tax need be paid if the Seller or one
of its subsidiaries is contesting the same in good faith by appropriate
proceedings promptly instituted and diligently conducted and if the Seller or
such subsidiary has established appropriate reserves as shall be required in
conformity with generally accepted accounting principles.

         Section 4.10. Additional Sales of Transition Property. So long as any
of the Notes are outstanding, the Seller shall not sell any transition property
(as defined in the Statute) to secure another issuance of electric rate
reduction bonds (as defined in the Statute) if it would cause the then existing

         Section 4.11. Issuance Advice Letter. The Seller hereby agrees not to
withdraw the filing of the Issuance Advice Letter with the DTE.

                              ARTICLE V. THE SELLER

         Section 5.01. Liability of Seller; Indemnities.

         (a) The Seller shall be liable in accordance herewith only to the
extent of the obligations specifically undertaken by the Seller under this
Agreement.

         (b) (i) In the event of a breach by the Seller of any representation
and warranty specified in Sections 3.08(c) or 3.08(e) that has a material
adverse effect on the Certificateholders, the Seller shall repurchase the
Transition Property from the Note Issuer at a purchase price equal to the then
outstanding principal amount of the Notes and all accrued and unpaid interest
thereon, excluding any premium or penalty of any kind (the "Repurchase Price"),
as of the Repurchase Date; provided, however, that the Seller shall not be
obligated to repurchase the Transition Property if (A) within 90 days after the
date of occurrence thereof such breach is cured or the Seller takes remedial
action such that there is not and will not be a material adverse effect on the
Certificateholders as a result of such breach and (B) either (1) if the Seller
had, immediately prior to the breach, a long term debt rating of at least "A3"
by Moody's and "BBB" by S&P or the equivalent of "BBB" by any other Rating
Agency, and the Seller enters into a binding agreement with the Note Issuer to
pay any amounts necessary so that all interest payments due on the Notes during
such 90-day period will be paid in full, or (2) if the Seller does not have such
long term debt ratings, the Seller deposits, within two Business Days after such
breach, an amount in escrow with the Note Trustee sufficient, taking into
account amounts on deposit in the Collection Account which will be available for
such purpose, to pay all interest payments which will become due on the Notes
during such 90-day period.

                  (ii) In the event of a breach by the Seller of any
representation and warranty specified in Sections 3.01, 3.03, 3.04, 3.05,
3.08(a) or 3.08(b) that has a material adverse effect on the Certificateholders,
if within 90 days after the date of occurrence thereof such breach has not been
cured or the Seller has not taken remedial action such that there is not and
will not be a material adverse effect on the Certificateholders as a result of
such breach, then the Seller shall repurchase the Transition Property from the
Note Issuer for the Repurchase Price on the Repurchase Date.

                  (iii) Notwithstanding any other provision of this Agreement,
upon the payment by the Seller of the Repurchase Price pursuant to this Section
5.01(b), neither the Note Issuer nor any other Person shall have any other
claims, rights or remedies against the Seller under, arising from or with
respect to this Agreement, except as set forth in Section 5.01(h).

         (c) The Seller shall indemnify the Note Issuer, the Note Trustee, the
Certificate Trustee, the Delaware Trustee, the Agencies, the Certificate Issuer,
the Noteholders and the Certificateholders for, and defend and hold harmless
each such Person from and against, any and all taxes (other than taxes imposed
on Noteholders or Certificateholders solely as a result of their

                                      -13-
<PAGE>   17
ownership of Notes or Certificates, respectively) that may at any time be
imposed on or asserted against any such Person under existing law as of the
Closing Date as a result of the sale of the Transition Property to the Note
Issuer, including any sales, gross receipts, general corporation, tangible
personal property, privilege or license taxes; provided, however, that the
Noteholders and the Certificateholders shall be entitled to enforce their rights
against the Seller under this Section 5.01(c) solely through a cause of action
brought for their benefit by the Note Trustee or the Certificate Trustee, as the
case may be.

         (d) The Seller shall indemnify the Note Issuer, the Note Trustee, the
Certificate Trustee, the Delaware Trustee, the Agencies, the Certificate Issuer,
the Noteholders and the Certificateholders for, and defend and hold harmless
each such Person from and against, any and all taxes that may be imposed on or
asserted against any such Person under existing law as of the Closing Date as a
result of the issuance and sale by the Note Issuer of the Notes, the issuance
and sale by the Trust of the Certificates or the other transactions contemplated
herein, including any sales, gross receipts, general corporation, tangible
personal property, privilege or license taxes; provided, however, that the
Noteholders and the Certificateholders shall be entitled to enforce their rights
against the Seller under this Section 5.01(d) solely through a cause of action
brought for their benefit by the Note Trustee or the Certificate Trustee, as the
case may be. The Seller shall be reimbursed for any payments under this Section
5.01(d) from RTC Charge Collections as an Operating Expense in accordance with
the priorities set forth in Section 8.02(d) of the Note Indenture.

         (e) The Seller shall indemnify the Note Issuer, the Noteholders and the
Certificateholders for, and defend and hold harmless each such Person from and
against, any and all liabilities, obligations, losses, actions, suits, claims,
damages, payments, costs or expenses of any kind whatsoever (collectively,
"Losses") that may be imposed on, incurred by or asserted against each such
Person as a result of (i) the Seller's willful misconduct or gross negligence in
the performance of its duties or observance of its covenants under this
Agreement, or (ii) the Seller's breach in any material respect of any of its
representations and warranties contained in this Agreement (other than the
representations and warranties specified in Sections 3.01, 3.03, 3.04, 3.05,
3.08(a), 3.08(b), 3.08(c) or 3.08(e), the breach of which are subject to the
repurchase obligation set forth in Section 5.01(b)), except in the case of both

misconduct or gross negligence of such indemnified person or resulting from a
breach of a representation and warranty made by such indemnified person in any
of the Basic Documents that gives rise to the Seller's breach; provided,
however, that the Noteholders and the Certificateholders shall be entitled to
enforce their rights against the Seller under this indemnification solely
through a cause of action brought for their benefit by the Note Trustee or the
Certificate Trustee, as the case may be; provided, further, that the Seller may,
at its election and in full satisfaction of its obligations under this Section
5.01(e), repurchase the Transition Property at the Repurchase Price, in which
case neither the Note Issuer nor any other Person shall have any other claims,
rights or remedies against the Seller under, arising from or with respect to
this Agreement, except as set forth in Section 5.01(h).

                                      -14-

5.01(h) shall include reasonable fees and out-of-pocket expenses of
investigation and litigation (including reasonable attorneys' fees and
expenses), except as otherwise provided in this Agreement.

         (g) Without prejudice to any of the other rights of the parties, the
Seller will not be in breach of any representation or warranty as a result of a
change in law by means of a legislative enactment, constitutional amendment or
voter initiative. Notwithstanding anything to the contrary in this Agreement,
the Seller makes no representation or warranty that any amounts actually
collected in respect of the RTC Charge will in fact be sufficient to meet
payment obligations with respect to the Notes and the Certificates or that the
assumptions used in calculating the RTC Charge will in fact be realized nor
shall the Seller be obligated to reduce, or accept a reduction of, any rates or
charges to which it would otherwise be entitled in respect of services rendered
or to be rendered to customers in order to permit the payment of the RTC Charge.

         (h) The Seller shall indemnify and hold harmless the Note Trustee, the
Delaware Trustee, the Certificate Trustee, the Certificate Issuer, the Agencies
and any of their respective affiliates, officers, directors, employees and
agents (each an "Indemnified Person") against any and all Losses incurred by any
of such Indemnified Persons as a result of (i) the Seller's willful misconduct
or gross negligence in the performance of its duties or observance of its
covenants under this Agreement or (ii) the Seller's breach in any material
respect of any of its representations and warranties contained in this
Agreement, except in the case of both clauses (i) and (ii) to the extent of
Losses either resulting from the willful misconduct or gross negligence of such
Indemnified Person or resulting from a breach of a representation or warranty
made by such Indemnified Person in any of the Basic Documents that gives rise to
the Seller's breach. The Seller shall not be required to indemnify an
Indemnified Person for any amount paid or payable by such Indemnified Person in
the settlement of any action, proceeding or investigation without the written
consent of the Seller, which consent shall not be unreasonably withheld.
Promptly after receipt by an Indemnified Person of notice of its involvement in
any action, proceeding or investigation, such Indemnified Person shall, if a
claim for indemnification in respect thereof is to be made against the Seller
under this Section 5.01(h), notify the Seller in writing of such involvement.
Failure by an Indemnified Person to so notify the Seller shall relieve the
Seller from the obligation to indemnify and hold harmless such Indemnified
Person under this Section 5.01(h) only to the extent that the Seller suffers
actual prejudice as a result of such failure. With respect to any action,
proceeding or investigation brought by a third party for which indemnification
may be sought under this Section 5.01(h), the Seller shall be entitled to assume
the defense of any such action, proceeding or investigation. Upon assumption by
the Seller of the defense of any such action, proceeding or investigation, the
Indemnified Person shall have the right to participate in such action or
proceeding and to retain its own counsel. The Seller shall be entitled to
appoint counsel of the Seller's choice at the Seller's expense to represent the
Indemnified Person in any action, proceeding or investigation for which a claim
of indemnification is made against the Seller under this Section 5.01(h) (in
which case the Seller shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by

                                      -15-
<PAGE>   19
the Indemnified Person except as set forth below); provided, however, that such
counsel shall be reasonably satisfactory to the Indemnified Person.
Notwithstanding the Seller's election to appoint counsel to represent the
Indemnified Person in an action, proceeding or investigation, the Indemnified
Person shall have the right to employ separate counsel (including local
counsel), and the Seller shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the Seller to
represent the Indemnified Person would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the Indemnified Person and the Seller and the Indemnified
Person shall have reasonably concluded that there may be legal defenses
available to it that are different from or additional to those available to the
Seller, (iii) the Seller shall not have employed counsel reasonably satisfactory
to the Indemnified Person to represent the Indemnified Person within a
reasonable time after notice of the institution of such action or (iv) the
Seller shall authorize the Indemnified Person to employ separate counsel at the
expense of the Seller. Notwithstanding the foregoing, the Seller shall not be
obligated to pay for the fees, costs and expenses of more than one separate
counsel for the Indemnified Persons other than local counsel. The Seller will
not, without the prior written consent of the Indemnified Person, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought under this Section 5.01(h) (whether or not the
Indemnified Person is an actual or potential party to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of the Indemnified Person from all liability arising out of such claim, action,
suit or proceeding.

         (i) The remedies of the Note Issuer, the Noteholders and the
Certificateholders provided in this Agreement are each such Person's sole and
exclusive remedies against the Seller for breach of its representations and
warranties in this Agreement.

         (j) For purposes of this Section 5.01, the term "Agencies" shall
include the Executive Office for Administration and Finance of The Commonwealth
of Massachusetts.

         Section 5.02. Merger or Consolidation of, or Assumption of the
Obligations of, Seller. Any Person (a) into which the Seller may be merged or
consolidated, (b) that may result from any merger or consolidation to which the
Seller shall be a party or (c) that may succeed to the properties and assets of
the Seller substantially as a whole, which Person in any of the foregoing cases
executes an agreement of assumption to perform every obligation of the Seller
hereunder, shall be the successor to the Seller under this Agreement without
further act on the part of any of the parties to this Agreement; provided,
however, that (i) if the Seller is the Servicer, no Servicer Default, and no
event which, after notice or lapse of time, or both, would become a Servicer
Default shall have occurred and be continuing, (ii) the Seller shall have
delivered to the Note Issuer and the Note Trustee an Officers' Certificate
stating that such consolidation, merger or succession and such agreement of
assumption comply with this Section and that all conditions precedent, if any,
provided for in this Agreement relating to such transaction have been complied
with, (iii) the Seller shall have delivered to the Note Issuer and the Note
Trustee an Opinion of Counsel either (A) stating that, in the opinion of such
counsel, all filings to be made by the

                                      -16-
<PAGE>   20
Seller, including filings with the DTE pursuant to the Statute, have been
executed and filed that are necessary to fully preserve and protect the interest
of the Note Issuer in the Transition Property and reciting the details of such
filings, or (B) stating that, in the opinion of such counsel, no such action
shall be necessary to preserve and protect such interests and (iv) the Rating
Agencies shall have received prior written notice of such transaction. When any
Person acquires the properties and assets of the Seller substantially as a whole
and becomes the successor to the Seller in accordance with the terms of this
Section 5.02, then upon satisfaction of all of the other conditions of this
Section 5.02, the Seller shall automatically and without further notice be
released from all of its obligations hereunder.

         Section 5.03. Limitation on Liability of Seller and Others. The Seller
and any director, officer, employee or agent of the Seller may rely in good
faith on the advice of counsel or on any document of any kind, prima facie
properly executed and submitted by any Person, respecting any matters arising
hereunder.

                      ARTICLE VI. MISCELLANEOUS PROVISIONS

         Section 6.01. Amendment. This Agreement may be amended by the Seller
and the Note Issuer, with ten Business Days' prior written notice given to the
Rating Agencies and the prior written consent of the Note Trustee, but without
the consent of any of the Noteholders, to cure any ambiguity, to correct or
supplement any provisions in this Agreement or for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions in
this Agreement or of modifying in any manner the rights of the Noteholders;
provided, however, that such action shall not, as evidenced by an Officer's
Certificate delivered to the Note Issuer and the Note Trustee, adversely affect
in any material respect the interests of any Noteholder.

         This Agreement may also be amended from time to time by the Seller and
the Note Issuer, with ten Business Days' prior written notice given to the
Rating Agencies and the prior written consent of the Note Trustee and the prior
written consent of the Holders of Notes evidencing not less than a majority of
the Outstanding Amount of the Notes affected thereby, for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement or of modifying in any manner the rights of the Noteholders.

         It shall not be necessary for the consent of Noteholders pursuant to
this Section to approve the particular form of any proposed amendment or
consent, but it shall be sufficient if such consent shall approve the substance
thereof.

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

                  underlying the calculation of the RTC Charge, including energy
                  usage volume, the rate of charge-offs and estimated expenses
                  and fees of the Note Issuer and the Certificate Issuer to the

                  such updated assumptions; and (D) determine the RTC Charge to

                  Anniversary True-Up Letter with the DTE no later than March 15

                  file a Routine True-Up Letter at least 15 days before the end
                  of any calendar quarter or Payment Date at such times as it
                  may reasonably determine to meet the Required Debt Service for
                  the then current Remittance Period.

                           (iii) The Servicer shall take all reasonable actions
                  and make all reasonable efforts to secure any Periodic
                  Adjustments.

                  (c) Non-Routine Periodic Adjustments.

                           (i) Whenever the Servicer determines that the
                  existing model for calculating the RTC Charge should be
                  amended or revised, subject to the consent of the Note Issuer
                  under the conditions set forth in Section 3.18 of the Note
                  Indenture, the Servicer shall file a Non-Routine True-Up
                  Letter with the DTE designating the adjustments to such model
                  and any corresponding adjustments to the RTC Charge
                  (collectively, a "Non-Routine Periodic Adjustment"), subject
                  to the review and approval of the DTE pursuant to the
                  Financing Order.

                           (ii) The Servicer shall take all reasonable actions
                  and make all reasonable efforts to secure any Non-Routine
                  Periodic Adjustments.

                            (iii) The Servicer shall implement any resulting
                  adjustments to the model and any resulting revised RTC Charge
                  as of the effective date of the Non- Routine True-Up Letter.

                  (d) Reports.

                           (i) Notification of Advice Letter Filings and
                  Periodic Adjustments. Whenever the Servicer files an Advice
                  Letter with the DTE, the Servicer shall send a copy of such
                  filing to the Note Issuer, the Note Trustee, the Certificate

                  Periodic Adjustment requested in any such Advice Letter filing
                  does not become effective on the applicable date as provided
                  by the Financing Order, the Servicer shall notify the Note
                  Issuer, the Note Trustee, the Certificate Trustee and the

                  Notes are outstanding, not later than fifteen (15) days after
                  the end of each month after the Certificates are issued
                  (excluding July, 1999), or if such day is not a Servicer
                  Business Day, the next succeeding Servicer Business Day, the
                  Servicer shall deliver a written report substantially in the

                  Notes are outstanding, not later than the Servicer Business
                  Day immediately preceding each Payment Date, the Servicer
                  shall deliver a written report substantially in the form of
                  Exhibit D hereto (the "Semiannual Servicer Certificate") to
                  the Note Issuer, the Note Trustee, the Certificate Trustee and

                  Rating Agencies, upon request, any publicly available reports
                  filed by the Servicer with the DTE (or otherwise made publicly
                  available by the Servicer) relating to TPSs and any other
                  non-confidential and non-proprietary information relating to
                  TPSs reasonably requested by the Rating Agencies.

         Section 4.02 Limitation of Liability.

                  (a) The Note Issuer and the Servicer expressly agree and
         acknowledge that:

                           (i) In connection with any Periodic Adjustment, the

                  agent hereunder.

                           (ii) Neither the Servicer nor the Note Issuer shall
                  be responsible in any manner for, and shall have no liability
                  whatsoever as a result of, any action, decision, ruling or
                  other determination made or not made, or any delay (other than
                  any delay resulting from the Servicer's failure to file the
                  applications required by Section 4.01 in a timely and correct
                  manner or other material breach by the Servicer of its duties
                  under this Agreement that materially and adversely affects the
                  Periodic Adjustments), by the DTE in any way related to the
                  Transition Property or in connection with any Periodic
                  Adjustment or Non-Routine Periodic Adjustment, the subject of
                  any filings under Section 4.01, any proposed Periodic

                  Adjustment or Non-Routine Periodic Adjustment, or the approval
                  of the RTC Charge and the adjustments thereto.

                           (iii) The Servicer shall have no liability whatsoever
                  relating to the calculation of the RTC Charge and the
                  adjustments thereto (including any Non- Routine Periodic
                  Adjustment), including as a result of any inaccuracy of any of
                  the assumptions made in such calculation regarding expected
                  energy usage volume, the rate of charge-offs, estimated
                  expenses and fees of the Note Issuer and the Certificate
                  Issuer, so long as the Servicer has not acted in a grossly
                  negligent manner in connection therewith, nor shall the
                  Servicer have any liability whatsoever as a result of any
                  Person, including the Noteholders or the Certificateholders,
                  not receiving any payment, amount or return anticipated or
                  expected in respect of any Note or Certificate generally,
                  except only to the extent that the Servicer is liable under
                  Section 6.02 of this Agreement.

                  (b) Notwithstanding the foregoing, this Section 4.02 shall not
         relieve the Servicer of any liability under Section 6.02 for any
         misrepresentation by the Servicer under Section 6.01 or for any breach
         by the Servicer of its obligations under this Agreement.

         Section 4.03 Remittances; Reconciliations.

                  (a) Subject to Section 4.03(b) below, on each Servicer
         Business Day commencing 45 days after the date of this Agreement, the
         Servicer shall cause to be made within two (2) Servicer Business Days
         of deemed receipt a wire transfer of immediately available funds to the
         General Subaccount of the Collection Account in an amount equal to the
         Estimated RTC Charge Payments (as calculated in accordance with Annex I
         hereto) received on such day and on any prior day that was not a
         Servicer Business Day for which a Remittance has not previously been
         made (taking into account the Weighted Average Days Outstanding in
         effect from time to time). Prior to or simultaneous with each
         Remittance to the General Subaccount of the Collection Account pursuant
         to this Section, the Servicer shall provide written notice to the Note
         Trustee of each such Remittance (including the exact dollar amount to
         be remitted).

                  (b) On or before each March 1, the Servicer shall calculate
         the amount of any Remittance Shortfall or Remittance Excess
         attributable to the prior Reconciliation Period and (A) if a Remittance
         Shortfall exists, the Servicer shall make a supplemental wire transfer
         of immediately available funds to the General Subaccount of the
         Collection Account on the next Servicer Business Day following such
         calculation in the amount of such Remittance Shortfall, or (B) if a
         Remittance Excess exists, the Servicer may elect to either reduce the
         amount of Remittances to be made to the Note Issuer on succeeding
         Servicer Business Days or receive a payment or payments on succeeding
         Payment Dates from the Note Issuer equal to the amount of such
         Remittance Excess until the balance of

                                       13
<PAGE>   18
         the Remittance Excess has been reduced to zero. The Servicer shall
         deliver a written report setting forth in reasonable detail the
         calculation of any Remittance Excess or Remittance Shortfall to the
         Note Issuer, the Note Trustee, the Certificate Trustee and the Rating
         Agencies.

                  (c) The Servicer agrees and acknowledges that it will remit
         Estimated RTC Charge Payments in accordance with this Section 4.03
         without any surcharge, fee, offset, charge or other deduction except
         (i) as set forth in Section 4.03(b) above and (ii) for late fees
         permitted by Section 6.06.


                       ARTICLE V. THE TRANSITION PROPERTY

         Section 5.01 Custody of Transition Property Records. To assure uniform
quality in servicing the Transition Property and to reduce administrative costs,
the Note Issuer hereby revocably appoints the Servicer, and the Servicer hereby
accepts such appointment, to act as the agent of the Note Issuer and the Note
Trustee as custodian of any and all documents and records that the Servicer
shall keep on file, in accordance with its customary procedures, relating to the
Transition Property, including copies of the Financing Order and Advice Letters
relating thereto and all documents filed with the DTE in connection with any
Periodic Adjustment or Non- Routine Periodic Adjustment and computational
records relating thereto (collectively, the "Transition Property Records"),
which are hereby constructively delivered to the Note Trustee, as pledgee of the
Note Issuer with respect to all Transition Property.

         Section 5.02 Duties of Servicer as Custodian.

                  (a) Safekeeping. The Servicer shall hold the Transition
         Property Records on behalf of the Note Issuer and maintain such
         accurate and complete accounts, records and computer systems pertaining
         to the Transition Property Records on behalf of the Note Issuer and the
         Note Trustee as shall enable the Note Issuer to comply with this
         Agreement and the Note Indenture. In performing its duties as custodian
         the Servicer shall act with reasonable care, using that degree of care
         and diligence that the Servicer exercises with respect to comparable
         assets that the Servicer services for itself or, if applicable, for
         others. The Servicer shall promptly report to the Note Issuer and the
         Note Trustee any failure on its part to hold the Transition Property
         Records and maintain its accounts, records and computer systems as
         herein provided and promptly take appropriate action to remedy any such
         failure. Nothing herein shall be deemed to require an initial review or
         any periodic review by the Note Issuer or the Note Trustee of the
         Transition Property Records. The Servicer's duties to hold the
         Transition Property Records on behalf of the Note Issuer set forth in
         this Section 5.02, to the extent such Transition Property Records have
         not been previously transferred to a successor Servicer pursuant to
         Article VII, shall terminate one year and one day after the earlier of
         the date on which (i)

                                       14
<PAGE>   19
         the Servicer is succeeded by a successor Servicer in accordance with
         Article VII hereof and (ii) no Notes are outstanding.

                  (b) Maintenance of and Access to Records. The Servicer shall
         maintain at all times records and accounts that permit the Servicer to
         identify RTC Charges billed. The Servicer shall maintain the Transition
         Property Records in Boston, Massachusetts or at such other office as
         shall be specified to the Note Issuer and the Note Trustee by written
         notice at least 30 days prior to any change in location. The Servicer
         shall make available for inspection to the Note Issuer and the Note
         Trustee or their respective duly authorized representatives, attorneys
         or auditors the Transition Property Records at such times during normal
         business hours as the Note Issuer or the Note Trustee shall reasonably
         request and which do not unreasonably interfere with the Servicer's
         normal operations. Nothing in this Section 5.02(b) shall affect the
         obligation of the Servicer to observe any applicable law (including any
         DTE Regulations) prohibiting disclosure of information regarding the
         Customers, and the failure of the Servicer to provide access to such
         information as a result of such obligation shall not constitute a
         breach of this Section 5.02(b).

                  (c) Release of Documents. Upon instruction from the Note
         Trustee in accordance with the Note Indenture, the Servicer shall
         release any Transition Property Records to the Note Trustee, the Note
         Trustee's agent or the Note Trustee's designee, as the case may be, at
         such place or places as the Note Trustee may designate, as soon as
         practicable.

                  (d) Defending Transition Property Against Claims. The
         Servicer, on behalf of the Noteholders and the Certificateholders,
         shall institute any action or proceeding necessary to compel
         performance by the DTE or The Commonwealth of Massachusetts of any of
         their obligations or duties under the Statute, the Financing Order or
         any Advice Letter, and the Servicer agrees to take such legal or
         administrative actions, including defending against or instituting and
         pursuing legal actions and appearing or testifying at hearings or
         similar proceedings, as may be reasonably necessary to block or
         overturn any attempts to cause a repeal of, modification of or
         supplement to the Statute or the Financing Order or the rights of
         holders of Transition Property by legislative enactment, voter
         initiative or constitutional amendment that would be adverse to
         Certificateholders. The costs of any such action shall be payable from
         RTC Charge Collections as an Operating Expense in accordance with the
         priorities set forth in Section 8.02(d) of the Note Indenture. The
         Servicer's obligations pursuant to this Section 5.02 shall survive and
         continue notwithstanding the fact that the payment of Operating
         Expenses pursuant to Section 8.02(d) of the Note Indenture may be
         delayed (it being understood that the Servicer may be required to
         advance its own funds to satisfy its obligations hereunder).

         Section 5.03 Instructions; Authority to Act. For so long as any Notes
remain outstanding, the Servicer shall be deemed to have received proper
instructions with respect to the

                                       15
<PAGE>   20
Transition Property Records upon its receipt of written instructions signed by a
Responsible Officer (as defined in the Note Indenture) of the Note Trustee.

         Section 5.04 Effective Period and Termination. The Servicer's
appointment as custodian shall become effective as of the Closing Date and shall
continue in full force and effect until terminated pursuant to this Section
5.04. If any Servicer shall resign as Servicer in accordance with the provisions
of this Agreement or if all of the rights and obligations of any Servicer shall
have been terminated under Section 7.01, the appointment of such Servicer as
custodian shall terminate upon appointment of a successor Servicer, subject to
the approval of the DTE, and acceptance by such successor Servicer of such
appointment.

         Section 5.05 Monitoring of Third-Party Suppliers. From time to time,
until the Retirement of the Notes, the Servicer shall, using the same degree of
care and diligence that it exercises with respect to payments owed to it for its
own account, implement such procedures and policies as are necessary to properly
enforce the obligations of each TPS to remit RTC Charges, in accordance with the
terms and provisions of the Financing Order, the TPS Service Agreement and
Schedule A to Annex I hereto.

         Section 5.06 Monitoring and Collecting Exit Charges. The Servicer
shall, using the same degree of care and diligence that it exercises with
respect to payments owed to it for its own account, bill and collect any exit
charges to which it may be entitled pursuant to Section 1G(g) of Chapter 164 of
the Massachusetts General Laws, and shall remit that portion of the exit charges
representing (or allocable to) the RTC Charge together with the Estimated RTC
Charge Payments for a particular billing date.


                            ARTICLE VI. THE SERVICER

         Section 6.01 Representations and Warranties of Servicer. The Servicer
makes the following representations and warranties, as of the Closing Date, on
which the Note Issuer is deemed to have relied in entering into this Agreement
relating to the servicing of the Transition Property.

                  (a) Organization and Good Standing. The Servicer is duly
         organized and validly existing as a corporation in good standing under
         the laws of The Commonwealth of Massachusetts, with the requisite
         corporate power and authority to own its properties as such properties
         are currently owned and to conduct its business as such business is now
         conducted by it, and has the requisite corporate power and authority to
         service the Transition Property and to hold the Transition Property
         Records as custodian.

                  (b) Due Qualification. The Servicer is duly qualified to do
         business as a foreign corporation in good standing, and has obtained
         all necessary licenses and approvals, in all jurisdictions in which the
         ownership or lease of property or the conduct

                                       16
<PAGE>   21
         of its business (including the servicing of the Transition Property as
         required by this Agreement) shall require such qualifications, licenses
         or approvals (except where the failure to so qualify or obtain such
         licenses and approvals would not be reasonably likely to have a
         material adverse effect on the Servicer's business, operations, assets,
         revenues or properties or adversely affect the servicing of the
         Transition Property).

                  (c) Power and Authority. The Servicer has the requisite
         corporate power and authority to execute and deliver this Agreement and
         to carry out its terms; and the execution, delivery and performance of
         this Agreement have been duly authorized by all necessary corporate
         action on the part of the Servicer.

                  (d) Binding Obligation. This Agreement constitutes a legal,
         valid and binding obligation of the Servicer enforceable against it in
         accordance with its terms, subject to applicable insolvency,
         reorganization, moratorium, fraudulent transfer and other laws relating
         to or affecting creditors' rights generally from time to time in effect
         and to general principles of equity (including concepts of materiality,
         reasonableness, good faith and fair dealing), regardless of whether
         considered in a proceeding in equity or at law.

                  (e) No Violation. The consummation of the transactions
         contemplated by this Agreement and the fulfillment of the terms hereof
         do not: (i) conflict with or result in any breach of any of the terms
         and provisions of, nor constitute (with or without notice or lapse of
         time) a default under, the articles of organization or by-laws of the
         Servicer, or any material indenture, agreement or other instrument to
         which the Servicer is a party or by which it is bound; (ii) result in
         the creation or imposition of any Lien upon any of the Servicer's
         properties pursuant to the terms of any such indenture, agreement or
         other instrument; nor violate any existing law or any existing order,
         rule or regulation applicable to the Servicer of any court or of any
         federal or state regulatory body, administrative agency or other
         governmental instrumentality having jurisdiction over the Servicer or
         its properties, so as to adversely affect the Servicer, the Noteholders
         or the Certificateholders.

                  (f) No Proceedings. There are no proceedings pending and, to
         the Servicer's knowledge, there are no proceedings threatened and, to
         the Servicer's knowledge, there are no investigations pending or
         threatened, before any court, federal or state regulatory body,
         administrative agency or other governmental instrumentality having
         jurisdiction over the Servicer or its properties involving or relating
         to the Servicer or the Note Issuer or, to the Servicer's knowledge, any
         other Person: (i) asserting the invalidity of this Agreement; (ii)
         seeking to prevent the consummation of any of the transactions
         contemplated by this Agreement; or (iii) seeking any determination or
         ruling that might materially and adversely affect the performance by
         the Servicer of its obligations under, or the validity or
         enforceability of, this Agreement.

                                       17
<PAGE>   22
                  (g) Approvals. No approval, authorization, consent, order or
         other action of, or filing with, any court, federal or state regulatory
         body, administrative agency or other governmental instrumentality is
         required in connection with the execution and delivery by the Servicer
         of this Agreement, the performance by the Servicer of the transactions
         contemplated hereby or the fulfillment by the Servicer of the terms
         hereof, except those that have been obtained or made and those that the
         Servicer is required to make in the future pursuant to Article III or
         IV hereof.

         Section 6.02 Indemnities of Servicer.

                  (a) The Servicer shall be liable in accordance herewith only
         to the extent of the obligations specifically undertaken by the
         Servicer and as expressly provided under this Section 6.02.

                  (b) The Servicer shall indemnify the Note Issuer, the
         Noteholders and the Certificateholders for, and defend and hold
         harmless each such Person from and against, any and all liabilities,
         obligations, losses, damages, payments, claims, costs or expenses of
         any kind whatsoever (collectively, "Losses") that may be imposed on,
         incurred by or asserted against any such Person as a result of (i) the
         Servicer's willful misconduct or gross negligence in the performance of
         its duties or observance of its covenants under this Agreement
         (including the Servicer's willful misconduct or gross negligence
         relating to the maintenance and custody by the Servicer, as custodian,
         of the Transition Property Records) or (ii) the Servicer's breach in
         any material respect of any of its representations or warranties in
         this Agreement; provided, however, that the Servicer shall not be
         liable for any Losses resulting from the willful misconduct or gross
         negligence of any such indemnified person; and, provided, further, that
         the Noteholders and the Certificateholders shall be entitled to enforce
         their rights and remedies against the Servicer under this Section
         6.02(b) solely through a cause of action brought for their benefit by
         the Note Trustee or the Certificate Trustee, as the case may be; and;
         provided, further, that the Servicer shall not be liable for any
         Losses, regardless of when incurred, after the Notes and the
         Certificates have been paid in full, except as provided in Section
         6.02(c).

                  (c) The Servicer shall indemnify and hold harmless the Note
         Trustee, the Delaware Trustee, the Certificate Trustee, the Certificate
         Issuer and the Agencies and any of their respective affiliates,
         officers, directors, employees and agents (each an "Indemnified
         Person") for, and defend and hold harmless each such Person from and
         against, any and all Losses imposed on, incurred by or asserted against
         any of such Indemnified Persons as a result of: (i) the Servicer's
         willful misconduct or gross negligence in the performance of its duties
         or observance of its covenants under this Agreement (including the
         Servicer's willful misconduct or gross negligence relating to the
         maintenance and custody by the Servicer, as custodian, of the
         Transition Property Records) or (ii) the Servicer's breach in any
         material respect of any of its representations

                                       18
<PAGE>   23
         or warranties in this Agreement; provided, however, that the Servicer
         shall not be liable for any Losses resulting from the willful
         misconduct or gross negligence of such Indemnified Person or resulting
         from a breach of a representation or warranty made by such Indemnified
         Person in any of the Basic Documents that gives rise to the Servicer's
         breach. The Servicer shall not be required to indemnify an Indemnified
         Person for any amount paid or payable by such Indemnified Person in the
         settlement of any action, proceeding or investigation without the
         written consent of the Servicer, which consent shall not be
         unreasonably withheld. Promptly after receipt by an Indemnified Person
         of notice of its involvement in any action, proceeding or
         investigation, such Indemnified Person shall, if a claim for
         indemnification in respect thereof is to be made against the Servicer
         under this Section 6.02(c), notify the Servicer in writing of such
         involvement. Failure by an Indemnified Person to so notify the Servicer
         shall relieve the Servicer from the obligation to indemnify and hold
         harmless such Indemnified Person under this Section 6.02(c) only to the
         extent that the Servicer suffers actual prejudice as a result of such
         failure. With respect to any action, proceeding or investigation
         brought by a third party for which indemnification may be sought under
         this Section 6.02(c), the Servicer shall be entitled to assume the
         defense of any such action, proceeding or investigation. Upon
         assumption by the Servicer of the defense of any such action,
         proceeding or investigation, the Indemnified Person shall have the
         right to participate in such action or proceeding and to retain its own
         counsel. The Servicer shall be entitled to appoint counsel of the
         Servicer's choice at the Servicer's expense to represent the
         Indemnified Person in any action, proceeding or investigation for which
         a claim of indemnification is made against the Servicer under this
         Section 6.02(c) (in which case the Servicer shall not thereafter be
         responsible for the fees and expenses of any separate counsel retained
         by the Indemnified Person except as set forth below); provided,
         however, that such counsel shall be reasonably satisfactory to the
         Indemnified Person. Notwithstanding the Servicer's election to appoint
         counsel to represent the Indemnified Person in an action, proceeding or
         investigation, the Indemnified Person shall have the right to employ
         separate counsel (including local counsel), and the Servicer shall bear
         the reasonable fees, costs and expenses of such separate counsel if (i)
         the use of counsel chosen by the Servicer to represent the Indemnified
         Person would present such counsel with a conflict of interest, (ii) the
         actual or potential defendants in, or targets of, any such action
         include both the Indemnified Person and the Servicer and the
         Indemnified Person shall have reasonably concluded that there may be
         legal defenses available to it that are different from or additional to
         those available to the Servicer, (iii) the Servicer shall not have
         employed counsel reasonably satisfactory to the Indemnified Person to
         represent the Indemnified Person within a reasonable time after notice
         of the institution of such action or (iv) the Servicer shall authorize
         the Indemnified Person to employ separate counsel at the expense of the
         Servicer. Notwithstanding the foregoing, the Servicer shall not be
         obligated to pay for the fees, costs and expenses of more than one
         separate counsel for the Indemnified Persons other than local counsel.
         The Servicer will not, without the prior written consent of the
         Indemnified Person, settle or compromise or consent to the entry of any
         judgment with respect to any pending or threatened claim,

                                       19
<PAGE>   24
         action, suit or proceeding in respect of which indemnification may be
         sought under this Section 6.02(c) (whether or not the Indemnified
         Person is an actual or potential party to such claim or action) unless
         such settlement, compromise or consent includes an unconditional
         release of the Indemnified Person from all liability arising out of
         such claim, action, suit or proceeding.

                  (d) Indemnification under Sections 6.02(b) and 6.02(c) shall
         include reasonable fees and out-of-pocket expenses of investigation and
         litigation (including reasonable attorneys' fees and expenses), except
         as otherwise provided in this Agreement.

                  (e) For purposes of Section 6.02(b) and 6.02(c), in the event
         of the termination of the rights and obligations of Boston Edison
         Company (or any successor thereto pursuant to Section 6.04) as Servicer
         pursuant to Section 7.01, or a resignation by such Servicer pursuant to
         this Agreement, such Servicer shall be deemed to be the Servicer
         pending appointment of a successor Servicer pursuant to Section 7.02.

                  (f) For purposes of this Section 6.02, the term "Agencies"
         shall include the Executive Office for Administration and Finance of
         The Commonwealth of Massachusetts.

         Section 6.03 Limitation on Liability of Servicer and Others. Except as
otherwise provided under this Agreement, neither the Servicer nor any of the
directors, officers, employees or agents of the Servicer shall be liable to the
Note Issuer or any other Person for any action taken or for refraining from the
taking of any action pursuant to this Agreement or for errors in judgment;
provided, however, that this provision shall not protect the Servicer or any
director, officer, employee or agent of the Servicer against any liability that
would otherwise be imposed by reason of willful misconduct or gross negligence
in the performance of duties under this Agreement. The Servicer and any
director, officer, employee or agent of the Servicer may rely in good faith on
the advice of counsel reasonably acceptable to the Note Trustee or on any
document of any kind, prima facie properly executed and submitted by any Person,
respecting any matters arising under this Agreement.

         Except as provided in this Agreement, the Servicer shall not be under
any obligation to appear in, prosecute or defend any legal action relating to
the Transition Property.

         Section 6.04 Merger or Consolidation of, or Assumption of the
Obligations of, Servicer. Any Person (a) into which the Servicer may be merged
or consolidated, (b) which may result from any merger or consolidation to which
the Servicer shall be a party or (c) which may succeed to the properties and
assets of the Servicer substantially as a whole, which Person in any of the
foregoing cases executes an agreement of assumption to perform every obligation
of the Servicer hereunder, shall be the successor to the Servicer under this
Agreement without further act on the part of any of the parties to this
Agreement; provided, however, that (i) immediately after giving

                                       20
<PAGE>   25
effect to such transaction, no Servicer Default and no event which, after notice
or lapse of time, or both, would become a Servicer Default shall have occurred
and be continuing, (ii) the Servicer shall have delivered to the Note Issuer and
the Note Trustee an Officers' Certificate stating that such consolidation,
merger or succession and such agreement of assumption comply with this Section
and that all conditions precedent provided for in this Agreement relating to
such transaction have been complied with, (iii) the Servicer shall have
delivered to the Note Issuer and the Note Trustee an Opinion of Counsel either
(A) stating that, in the opinion of such counsel, all statutory filings to be
made by the Servicer, including filings with the DTE pursuant to the Statute,
have been executed and filed that are necessary to preserve and protect fully
the interests of the Note Issuer in the Transition Property and reciting the
details of such filings or (B) stating that, in the opinion of such counsel, no
such action shall be necessary to preserve and protect such interests and (iv)
the Rating Agencies shall have received prior written notice of such
transaction. When any Person acquires the properties and assets of the Servicer
substantially as a whole and becomes the successor to the Servicer in accordance
with the terms of this Section 6.04, then upon satisfaction of all of the other
conditions of this Section 6.04, the Servicer shall automatically and without
further notice be released from all its obligations hereunder.

         Section 6.05 Boston Edison Company Not to Resign as Servicer. Subject
to the provisions of Section 6.04, Boston Edison Company shall not resign from
the obligations and duties hereby imposed on it as Servicer under this Agreement
except upon either (a) a determination that the performance of its duties under
this Agreement shall no longer be permissible under applicable law or (b)
satisfaction of the following: (i) the Rating Agency Condition shall have been
satisfied (except that with respect to Moody's it shall be sufficient to provide
ten days prior notice) and (ii) the DTE shall have approved such resignation.
Notice of any such determination permitting the resignation of Boston Edison
Company shall be communicated to the Note Issuer, the Note Trustee, the
Certificate Trustee and the Rating Agencies at the earliest practicable time
(and, if such communication is not in writing, shall be confirmed in writing at
the earliest practicable time) and any such determination that the performance
of Boston Edison Company's duties under this Agreement shall no longer be
permissible under applicable law shall be evidenced by an Opinion of Counsel to
such effect delivered by Boston Edison Company to the Note Issuer, the Note
Trustee and the Certificate Trustee concurrently with or promptly after such
notice. No such resignation shall become effective until a successor Servicer
shall have assumed the responsibilities and obligations of Boston Edison Company
in accordance with Section 7.02.

         Section 6.06 Servicing Compensation.

                  (a) In consideration for its services hereunder, until the
         Retirement of the Notes, the Servicer shall receive an annual fee (the
         "Servicing Fee") in an amount equal to (i) five one-hundredth of one
         percent (0.05%) of the initial principal balance of the Notes for so
         long as Boston Edison Company or any successor Servicer bills the RTC
         Charge concurrently with other charges for services or (ii) up to one
         and one-quarter percent (1.25%) of the initial principal balance of the
         Notes if the RTC Charge is being

                                       21
<PAGE>   26
         billed separately to Customers (which amount shall be determined by a
         separate agreement between the Note Issuer and the Servicer). The
         Servicing Fee shall be payable in semiannual installments on each
         Payment Date. The Servicer also shall be entitled to retain as
         additional compensation (i) any interest earnings on Estimated RTC
         Charge Payments deemed received by the Servicer and invested by the
         Servicer pursuant to Section 6(c) of Annex I hereto prior to remittance
         to the Collection Account and (ii) all late payment charges, if any,
         collected from Customers or TPSs.

                  (b) The Servicing Fee set forth in Section 6.06(a) above and
         expenses provided for in Section 6.06(c) below shall be paid to the
         Servicer by the Note Trustee, on each Payment Date in accordance with
         the priorities set forth in Section 8.02(d) of the Note Indenture, by
         wire transfer of immediately available funds from the Collection
         Account to an account designated by the Servicer. Any portion of the
         Servicing Fee not paid on such date shall be added to the Servicing Fee
         payable on the subsequent Payment Date.

                  (c) The Note Issuer shall pay all expenses incurred by the
         Servicer in connection with its activities hereunder (including any
         fees to and disbursements by accountants, counsel, or any other Person,
         any taxes imposed on the Servicer (other than taxes based on the
         Servicer's net income) and any expenses incurred in connection with
         reports to Noteholders and Certificateholders, subject to the
         priorities set forth in Section 8.02(d) of the Note Indenture).

         Section 6.07 Compliance with Applicable Law. The Servicer covenants and
agrees, in servicing the Transition Property, to comply in all material respects
with all laws applicable to, and binding upon, the Servicer and relating to such
Transition Property the noncompliance with which would have a material adverse
effect on the value of the Transition Property; provided, however, that the
foregoing is not intended to, and shall not, impose any liability on the
Servicer for noncompliance with any law that the Servicer is contesting in good
faith in accordance with its customary standards and procedures.

         Section 6.08 Access to Certain Records and Information Regarding
Transition Property. The Servicer shall provide to the Noteholders, the Note
Trustee and the Certificate Trustee access to the Transition Property Records in
such cases where the Noteholders, the Note Trustee and the Certificate Trustee
shall be required by applicable law to be provided access to such records.
Access shall be afforded without charge, but only upon reasonable request and
during normal business hours at the respective offices of the Servicer. Nothing
in this Section shall affect the obligation of the Servicer to observe any
applicable law (including any DTE Regulation) prohibiting disclosure of
information regarding the Customers, and the failure of the Servicer to provide
access to such information as a result of such obligation shall not constitute a
breach of this Section.

         Section 6.09 Appointments. The Servicer may at any time appoint any
Person to perform all or any portion of its obligations as Servicer hereunder;
provided, however, that the Rating Agency Condition shall have been satisfied in
connection therewith (except that with respect to Moody's it shall be sufficient
to provide ten days prior notice); and, provided, further, that the Servicer
shall remain obligated and be liable under this Agreement for the servicing and
administering of the Transition Property in accordance with the provisions
hereof without diminution of such obligation and liability by virtue of the
appointment of such Person and to the same extent and under the same terms and
conditions as if the Servicer alone were servicing and administering the
Transition Property; and, provided, further, however, that nothing herein
(including the Rating Agency Condition) shall preclude the execution by the
Servicer of a TPS Service Agreement with any TPS pursuant to applicable DTE
Regulations. Notwithstanding anything to the contrary in this Agreement, the
parties hereto acknowledge and agree that the initial Servicer has appointed
Cash Management Services to process U.S. mail payments from Customers and that
such appointment is hereby permitted hereunder. The fees and expenses of any
such Person shall be as agreed between the Servicer and such Person from time to
time and none of the Note Issuer, the Note Trustee, the Noteholders or any other
Person shall have any responsibility therefor or right or claim thereto. Any
such appointment shall not constitute a Servicer resignation under Section 6.05.

         Section 6.10 No Servicer Advances. Except with respect to Remittances
of Estimated RTC Charge Payments, the Servicer shall not make any advances of
interest on or principal of the Notes or the Certificates.

         Section 6.11 Maintenance of Operations. The Servicer agrees to continue
to operate its distribution system to provide service to its customers so long
as it is acting as the Servicer under this Agreement.


                              ARTICLE VII. DEFAULT

         Section 7.01 Servicer Default. If any one of the following events (each
a "Servicer Default") shall occur and be continuing:

                  (a) any failure by the Servicer to remit to the Collection
         Account on behalf of the Note Issuer any required Remittance that shall
         continue unremedied for a period of five (5) Business Days after
         written notice of such failure is received by the Servicer from the
         Note Issuer or the Note Trustee; or

                  (b) any failure on the part of the Servicer duly to observe or
         to perform in any material respect any other covenants or agreements of
         the Servicer set forth in this Agreement, which failure shall (a)
         materially and adversely affect the rights of the Noteholders or
         Certificateholders and (ii) continue unremedied for a period of 60 days
         after the date on which written notice of such failure, requiring the
         same to be remedied, shall have been given (A) to the Servicer by the
         Note Issuer or (B) to the Servicer by the

                                       23
<PAGE>   28
         Note Trustee or by the Holders of Notes evidencing not less than 25
         percent of the Outstanding Amount of the Notes; or

                  (c) any representation or warranty made by the Servicer in
         this Agreement shall prove to have been incorrect in any material
         respect when made, which has a material adverse effect on the
         Noteholders or Certificateholders and which material adverse effect
         continues unremedied for a period of 60 days after written notice of
         such failure is received by the Servicer from the Note Issuer or the
         Note Trustee; or

                  (d) an Insolvency Event occurs with respect to the Servicer;

         then, and in each and every case, so long as the Servicer Default shall
         not have been remedied, either the Note Trustee, or the Holders of
         Notes evidencing not less than 25 percent of the Outstanding Amount of
         the Notes, by notice then given in writing to the Servicer (and to the
         Note Trustee if given by the Noteholders) (a "Termination Notice") may
         terminate all the rights and obligations (other than the obligations
         set forth in Section 6.02 hereof) of the Servicer under this Agreement.
         In addition, upon a Servicer Default described in Section 7.01(a), each
         of the following shall be entitled to apply to the DTE for
         sequestration and payment of revenues arising with respect to the
         Transition Property: (1) the Certificateholders and the Certificate
         Trustee as beneficiary of any statutory lien permitted by the Statute;
         (2) the Note Issuer or its assignees; (3) the Certificate Issuer or (4)
         pledgees or transferees, including transferees under Section 1H(f) of
         the Statute, of the Transition Property. On or after the receipt by the
         Servicer of a Termination Notice, and subject to the approval of the
         DTE, all authority and power of the Servicer under this Agreement,
         whether with respect to the Notes, the Transition Property, the RTC
         Charge or otherwise, shall, without further action, pass to and be
         vested in such successor Servicer as may be appointed under Section
         7.02; and, without limitation, the Note Trustee is hereby authorized
         and empowered to execute and deliver, on behalf of the predecessor
         Servicer, as attorney-in-fact or otherwise, any and all documents and
         other instruments, and to do or accomplish all other acts or things
         necessary or appropriate to effect the purposes of such Termination
         Notice, whether to complete the transfer of the Transition Property
         Records and related documents, or otherwise. The predecessor Servicer
         shall cooperate with the successor Servicer, the Note Issuer and the
         Note Trustee in effecting the termination of the responsibilities and
         rights of the predecessor Servicer under this Agreement, including the
         transfer to the successor Servicer for administration by it of all cash
         amounts that shall at the time be held by the predecessor Servicer for
         remittance, or shall thereafter be received by it with respect to the
         Transition Property or the RTC Charge. In case a successor Servicer is
         appointed as a result of a Servicer Default, all reasonable costs and
         expenses (including reasonable attorneys' fees and expenses) incurred
         in connection with transferring the Transition Property Records to the
         successor Servicer and amending this Agreement to reflect such
         succession as Servicer pursuant to this Section shall be paid by the
         predecessor Servicer upon presentation of reasonable documentation of
         such costs and expenses.

         Section 7.02 Appointment of Successor.

                  (a) Upon the Servicer's receipt of a Termination Notice
         pursuant to Section 7.01 or the Servicer's resignation or removal in
         accordance with the terms of this Agreement, the predecessor Servicer
         shall continue to perform its functions as Servicer under this
         Agreement, and shall be entitled to receive the requisite portion of
         the Servicing Fee and reimbursement of expenses as provided herein,
         until a successor Servicer shall have assumed in writing the
         obligations of the Servicer hereunder as described below. In the event
         of the Servicer's termination hereunder, the Note Issuer shall appoint,
         subject to the approval of the DTE, a successor Servicer with the Note
         Trustee's prior written consent thereto (which consent shall not be
         unreasonably withheld), and the successor Servicer shall accept its
         appointment by a written assumption in form reasonably acceptable to
         the Note Issuer and the Note Trustee. If within 30 days after the
         delivery of the Termination Notice, the Note Issuer shall not have
         obtained such a new Servicer, the Note Trustee may petition the DTE or
         a court of competent jurisdiction to appoint a successor Servicer under
         this Agreement. A Person shall qualify as a successor Servicer only if
         (i) such Person is permitted under DTE Regulations to perform the
         duties of the Servicer, (ii) the Rating Agency Condition shall have
         been satisfied and (iii) such Person enters into a servicing agreement
         with the Note Issuer having substantially the same provisions as this
         Agreement.

                  (b) Upon appointment, the successor Servicer shall be the
         successor in all respects to the predecessor Servicer and shall be
         subject to all the responsibilities, duties and liabilities arising
         thereafter relating thereto placed on the predecessor Servicer and
         shall be entitled to the Servicing Fee and all the rights granted to
         the predecessor Servicer by the terms and provisions of this Agreement.

         Section 7.03 Waiver of Past Defaults. The Holders of Notes evidencing
not less than a majority of the Outstanding Amount of the Notes may, on behalf
of all Noteholders, waive in writing any default by the Servicer in the
performance of its obligations hereunder and its consequences, except a default
in making any required Remittances to the Collection Account in accordance with
this Agreement. Upon any such waiver of a past default, such default shall cease
to exist, and any Servicer Default arising therefrom shall be deemed to have
been remedied for every purpose of this Agreement. No such waiver shall extend
to any subsequent or other default or impair any right consequent thereto.

         Section 7.04 Notice of Servicer Default. The Servicer shall deliver to
the Note Issuer, the Note Trustee, the Certificate Trustee, the Certificate
Issuer, the Agencies and the Rating Agencies, promptly after having obtained
knowledge thereof, but in no event later than five Business Days thereafter,
written notice in an Officers' Certificate of any event which with the giving of
notice or lapse of time, or both, would become a Servicer Default under Section
7.01(a) or (b).

                     ARTICLE VIII. MISCELLANEOUS PROVISIONS

         Section 8.01 Amendment. This Agreement may be amended in writing by the
Servicer and the Note Issuer with ten Business Days' prior written notice given
to the Rating Agencies and the prior written consent of the Note Trustee (which
consent shall not be unreasonably withheld), but without the consent of any of
the Noteholders, to cure any ambiguity, to correct or supplement any provisions
in this Agreement or for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions in this Agreement or of
modifying in any manner the rights of the Noteholders; provided, however, that
such action shall not, as evidenced by an Officer's Certificate delivered to the
Note Issuer and the Note Trustee, adversely affect in any material respect the
interests of any Noteholder or Certificateholder.

         This Agreement may also be amended in writing from time to time by the
Servicer and the Note Issuer with ten Business Days' prior written notice given
to the Rating Agencies and the prior written consent of the Note Trustee (which
consent shall not be unreasonably withheld) and the prior written consent of the
Holders of Notes evidencing not less than a majority of the Outstanding Amount
of the Notes, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Agreement or of modifying in
any manner the rights of the Noteholders; provided, however, that any amendment
of the provisions of Sections 4.01 or 4.03 of this Agreement shall satisfy the
Rating Agency Condition (except that with respect to Moody's it shall be
sufficient to provide ten days prior notice).

         It shall not be necessary for the consent of Noteholders pursuant to
this Section to approve the particular form of any proposed amendment or
consent, but it shall be sufficient if such consent shall approve the substance
thereof.

         The Note Issuer shall promptly provide each of the Rating Agencies with
a copy of any amendment to this Agreement.

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

         Section 8.02 Maintenance of Accounts and Records.

                  (a) The Servicer shall maintain accounts and records as to the
         Transition Property accurately and in accordance with its standard
         accounting procedures and in sufficient detail to permit reconciliation
         between RTC Charge Collections and Deemed RTC Charge Payments.

                  (b) The Servicer shall permit the Note Trustee and its agents
         at any time during normal business hours, upon reasonable notice to the
         Servicer and to the extent it does not unreasonably interfere with the
         Servicer's normal operations, to inspect, audit and make copies of and
         abstracts from the Servicer's records regarding the Transition Property
         and the RTC Charge. Nothing in this Section 8.02(b) shall affect the
         obligation of the Servicer to observe any applicable law (including any
         DTE Regulation) prohibiting disclosure of information regarding the
         Customers, and the failure of the Servicer to provide access to such
         information as a result of such obligation shall not constitute a
         breach of this Section 8.02(b).

         Section 8.03 Notices. Unless otherwise specifically provided herein,
all notices, directions, consents and waivers required under the terms and
provisions of this Agreement shall be in English and in writing, and any such
notice, direction, consent or waiver may be given by United States mail, courier
service, facsimile transmission or electronic mail (confirmed by telephone,
United States mail or courier service in the case of notice by facsimile
transmission or electronic mail) or any other customary means of communication,
and any such notice, direction, consent or waiver shall be effective when
delivered, or if mailed, three days after deposit in the United States mail with
proper postage for ordinary mail prepaid:

         shall be designated by written notice to the other parties.

         Section 8.04 Assignment. Notwithstanding anything to the contrary
contained herein, except as provided in Section 6.04 and as provided in the
provisions of this Agreement concerning the resignation of the Servicer, this
Agreement may not be assigned by the Servicer.

         Section 8.05 Limitations on Rights of Third Parties. The provisions of
this Agreement are solely for the benefit of the Servicer, the Note Issuer, the

expressly referred to herein and such Persons shall have the right to enforce
the relevant provisions of this Agreement, except that the Noteholders and the
Certificateholders shall be entitled to enforce their rights against the

benefit by the Note Trustee or the Certificate Trustee, as the case may be.
Nothing in this Agreement, whether express or implied, shall be construed to
give to any other Person any legal or equitable right, remedy or claim in the
Transition Property or under or in respect of this Agreement or any covenants,
conditions or provisions contained herein.

         Section 8.06 Severability. Any provision of this Agreement that is

unenforceable such provision in any other jurisdiction.

         Section 8.07 Separate Counterparts. This Agreement may be executed by
the parties hereto in separate counterparts, each of which when so executed and

Sections herein are for convenience of reference only and shall not define or
limit any of the terms or provisions hereof.

rights and remedies of the parties hereunder shall be determined in accordance
with such laws.

         Section 8.10 Assignment to Note Trustee. The Servicer hereby
acknowledges and consents to the collateral assignment of any or all of the Note

the holders of the Notes and to the further assignment of the Note Trustee's

the benefit of the holders of the Certificates.

the Transition Property notwithstanding any bankruptcy, reorganization or other
insolvency proceedings with respect to the debtor, pledgor or transferor of the
Transition Property pursuant to Sections 1H(d)(5) and 1H(e) of the Statute, the
Servicer shall not, prior to the date which is one year and one day after the

otherwise invoke or cause the Note Issuer or the Trust to invoke the process of
any court or governmental authority for the purpose of commencing or sustaining

ADVICE ____________

DEPARTMENT OF TELECOMMUNICATIONS AND ENERGY (THE "DEPARTMENT") OF THE
COMMONWEALTH OF MASSACHUSETTS

SUBJECT:  Periodic RTC Charge True-Up Mechanism Advice Filing

Pursuant to D.T.E. Docket No. 98-118 (the "Financing Order"), Boston Edison
Company ("Boston Edison") as servicer of the RRBs or any successor Servicer and
on behalf of the trustee as assignee of the special purpose entity (the "SPE")
may apply for adjustment to the RTC Charge on each anniversary of the date of
the Financing Order and at such additional intervals as may be provided for in
the Financing Order. Any capitalized terms not defined herein shall have the
meanings ascribed thereto in the Financing Order.

PURPOSE

This filing establishes the revised RTC Charge to be assessed and collected from
all classes of retail users of Boston Edison's distribution system within the
geographic service territory as in effect on July 1, 1997, whether or not energy
is purchased from Boston Edison or any TPS, and whether or not such distribution
system is being operated by Boston Edison or a successor distribution company.
The RTC Charge is a usage-based component of the transition charge on each
retail user's monthly bill and may include in the future a component of any exit
fee collected pursuant to G.L. c. 164, Section 1G(g) until the Total RRB Payment
Requirements are discharged in full. In the Financing Order, the Department
authorized Boston Edison to file Routine True-Up Letters prior to each
anniversary of the date of the Financing Order and at such additional intervals,
if necessary, as provided for in the Financing Order. Boston Edison, or a
successor Servicer, is authorized to file periodic RTC Charge adjustments to the
extent necessary to ensure the timely recovery of revenues sufficient to provide
for the payment of an amount equal to the sum of the Periodic RRB Payment
Requirements (as defined in the Financing Order) for the upcoming year, which
may include indemnity obligations of the SPE in the RRB transaction documents
for SPE officers and directors, trustee fees, liabilities of the special purpose
trust and liabilities to the underwriters related to the underwriting of the
RRBs. Routine True-Up Letter filings are those where Boston Edison uses the
methodology approved by the Department in the Financing Order to adjust upward
or downward the existing RTC Charge. Using the methodology approved by the
Department in the Financing Order, this filing modifies the variables used in
the RTC Charge calculation and provides the resulting modified RTC Charge. Table
I shows the revised assumptions for each of the variables used in calculating
the
<PAGE>   40
RTC Charge for retail users. The assumptions underlying the current RTC Charges
were filed in an Issuance Advice Letter, dated July 28, 1999.

Table I below shows the current assumptions for each of the variables used in
the RTC Charge calculation.

Charge adjustments shall be filed prior to the anniversary of the Financing
Order or more frequently, if necessary, with the resulting changes to be

Issuer on the date of this Agreement that the following statements are true and
correct:

                  a. The Note Issuer has been duly formed and is validly
existing and in good standing as a limited liability company under the laws of
the State of Delaware and has the limited liability power and authority to carry

<PAGE>   4
                  c. The Note Indenture has been duly authorized by the Note
Issuer and, on the Issuance Date, will have been validly executed and delivered
by the Note Issuer. When the Note Indenture has been duly executed and delivered

the Note Issuer, enforceable against the Note Issuer in accordance with its
terms except as (i) the enforceability thereof may be limited by bankruptcy,
insolvency, moratorium, reorganization, fraudulent transfer and other laws
relating to or affecting creditors' rights generally and (ii) the availability
of equitable remedies may be limited by equitable principles of general
applicability. On the Issuance Date, the Note Indenture will conform in all
material respects to the requirements of the Trust Indenture Act, and the rules
and regulations of the Commission applicable to an indenture which is qualified
thereunder.

                  d. The Notes have been duly authorized and, on the Issuance
Date, will have been validly executed and delivered by the Note Issuer. When the

Certificate Issuer in accordance with the terms of this Agreement, the Notes
will be entitled to the benefits of the Note Indenture and will be valid and
binding obligations of the Note Issuer, enforceable in accordance with their
terms except as (i) the enforceability thereof may be limited by bankruptcy,
insolvency, moratorium, reorganization, fraudulent transfer and other laws
relating to or affecting creditors' rights generally and (ii) the availability
of equitable remedies may be limited by equitable principles of general
applicability.

                  e. No Default or Event of Default under the Note Indenture
would occur as a result of the sale of the Notes pursuant to the terms hereof.

                  f. The execution, delivery and performance of this Agreement
and the other Basic Documents by the Note Issuer, compliance by the Note Issuer
with all provisions hereof and thereof and the consummation of the transactions
contemplated hereby and thereby will not (i) require any consent, approval,
authorization or other order of, or qualification with, any court or
governmental body or agency (except such as has been obtained or may be required
under the laws of The Commonwealth of Massachusetts, the Statute, the Securities
Act, or the securities or blue sky laws of the various states), (ii) conflict
with or constitute a material breach of any of the terms or provisions of, or a
default under, the limited liability company agreement of the Note Issuer, (iii)
violate or conflict in any material respect with any applicable law or any rule,
regulation, judgment, order or decree of any court or any governmental body or
agency having jurisdiction over the Note Issuer or its property, (iv) result in
the imposition or creation of a lien under, any agreement or instrument to which
the Note Issuer is a party or by which the Note Issuer or its respective
property is bound, except as may be created or imposed under the Basic Documents
and any statutory lien under Section 1H(e) of the Statute.

                  g. To the best knowledge of the Note Issuer, there are no
legal or governmental proceedings pending or threatened to which the Note Issuer
is or reasonably could be a party or to which any of its property is or
reasonably could be subject, which might result, singly or in the aggregate, in
a material adverse effect on the enforceability of the Notes.

                  h. The Note Issuer is not and, after giving effect to the
offering and sale of the Notes and the application of the net proceeds thereof
as described in the Registration Statement, will not be, an "investment
company," as such term is defined in the Investment Company Act of 1940, as
amended.

                  i. The Note Issuer is not and, after giving effect to the
offering and sale of the Notes and the application of the net proceeds thereof
as described in the Registration Statement, will not be, a "holding company," as
such term is defined in the Public Utilities Holding Company Act of 1935, as
amended.

                  j. The Note Issuer has not taken any action that might cause
this Agreement or the issuance or sale of the Notes to violate Regulation T (12
C.F.R. Part 220), Regulation U (12 C.F.R. Part 221) or Regulation X (12 C.F.R.
Part 224) of the Board of Governors of the Federal Reserve System.

                  k. Since the date as of which information is given in the
Registration Statement and other than as set forth in the Registration Statement
(exclusive of any amendments or supplements thereto subsequent to the date of
this Agreement), (i) there has not occurred any material adverse change in the
assets, business, management or operations of the Note Issuer and (ii) other
than the Notes and as contemplated by the Basic Documents, the Note Issuer has
not incurred any material liability or obligation, direct or contingent.

4.   COVENANTS

         The Note Issuer covenants and agrees that, until payment in full of the
Notes, unless the Delaware Trustee, on behalf of the Certificate Issuer, shall
otherwise give prior written consent, the Note Issuer shall perform all
covenants in this Section 4.

                  a. To advise the Delaware Trustee, as the representative of
the Certificate Issuer, the Agencies and the Certificate Trustee promptly and,
if requested by the Delaware Trustee, on behalf of the Certificate Issuer, the
Agencies or the Certificate Trustee, confirm such advice in writing, of the
issuance by the Commission or any state securities commission of any stop order
or an order suspending the qualification or exemption from qualification of any
Note or Certificate for offering or sale in any jurisdiction in which the
Certificates have been offered or the initiation of any proceeding by the
Commission, any state securities commission or any other federal or state
regulatory authority for such purpose. The Note Issuer shall use its best
efforts to prevent the issuance of any stop order or order suspending the
qualification or exemption of any Note or Certificate under the Securities Act,
or any state securities or blue sky laws and, if at any time the Commission or
any state securities commission or other federal or state regulatory authority
shall issue a stop order or an order suspending the qualification or exemption
of any Note or Certificate under the Securities Act or any state securities or
blue sky laws, the Note Issuer shall use its reasonable efforts to obtain the
withdrawal or lifting of such order at the earliest possible time.

                  b. To the extent permitted by applicable law, not to claim
voluntarily the benefit of any usury laws against the holders of any Notes. To
the extent permitted by applicable law, to

                                       4

the Certificate Issuer, the Agencies, or the Certificate Trustee, to provide, or
cause to be provided, to the Delaware Trustee as the representative of the
Certificate Issuer, the Agencies or the Certificate Trustee, as applicable, a

Indenture.

the Administrator and the Note Issuer with the written consent of the Note
Trustee, but without the consent of any of the Noteholders or

consents, the Administrator shall furnish written notification of the substance
of such amendment to the Note Trustee and each of the Rating Agencies.

         Approval by Noteholders of the substance of any proposed amendment or
consent shall constitute sufficient consent of the Noteholders pursuant to this
Section, and it shall not be necessary that Noteholders approve of the
particular form of any amendment or consent.

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

         Section 5.08 Successors and Assigns. This Agreement may not be assigned
by the Administrator unless such assignment is previously consented to in
writing by the Note Issuer and the Note Trustee and is subject to the
satisfaction of the Rating Agency Condition in respect thereof. An assignment
with such consent and satisfaction, if accepted by the assignee, shall bind the
assignee hereunder in the same manner as the Administrator is bound hereunder.
Notwithstanding the foregoing, this Agreement may be assigned by the
Administrator without the consent of the Note Issuer and the Note Trustee to a
corporation or other organization that is a successor (by merger, consolidation
or purchase of assets) to the Administrator, provided that such successor
organization executes and delivers to the Note Issuer and the Note Trustee an
agreement in which such corporation or other organization agrees to be bound

Administrator is bound hereunder and the Rating Agency Condition is satisfied.

the Certificateholders shall be entitled to enforce their rights and remedies
against the Administrator under this agreement solely through a cause of action
brought for their benefit by the Note Trustee or the Certificate Trustee, as the
case may be, and nothing in this Agreement, whether express or implied, shall be
construed to give to any other Person any legal or equitable right, remedy or
claim in the Transition Property or under or in respect of this Agreement or any
covenants, conditions or provisions contained herein, except for the indemnities
specifically provided in Section 5.15. The Persons listed in this section as
having the benefit of this Agreement and the indemnified Persons listed in

remaining provisions hereof and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

termination of this Agreement or the Note Indenture, but subject to the DTE's
right to order the sequestration and payment of revenues arising with respect to
the Transition Property notwithstanding any bankruptcy, reorganization or other
insolvency proceedings with respect to the Seller of the Transition Property

to the date which is one year and one day after the termination of the Note
Indenture with respect to the Note Issuer, petition or otherwise invoke or cause
the Note Issuer or the Trust to invoke the process of any court or government
authority for the purpose of commencing or sustaining a case against the Note
Issuer or the Trust under any Federal or state bankruptcy, insolvency or similar

against the Administrator under this indemnification solely through a cause of
action brought for their benefit by the Note Trustee or the Certificate Trustee,

any such tax.

         (d) Notwithstanding anything herein to the contrary, if the Certificate
Trustee shall have entered into a fee agreement in writing with the Certificate
Issuer with respect to the
<PAGE>   3
Certificate Trustee's compensation for services under the Certificate Indenture,

Delaware Trustee, arising out of or in connection with the acceptance or
administration of the Trust Property under the Declaration of Trust (other than
any tax attributable to the Delaware Trustee's compensation for serving as
such), including any costs and expenses incurred in contesting the imposition of

         (c) Notwithstanding anything herein to the contrary, if the Delaware
Trustee shall have entered into a fee agreement in writing with the Certificate
Issuer with respect to its compensation for services under the Declaration of
Trust and the Certificate Indenture, the terms of such other fee agreement shall
control and the provisions of this Agreement shall not entitle the Delaware
Trustee to greater compensation than that due and owing pursuant to such fee
agreement.

         Section 3. Indemnity and Contribution.

         (a) The Note Issuer hereby covenants and agrees to indemnify, defend
and hold harmless the Delaware Trustee, the Certificate Trustee, the Certificate

nature whatsoever (collectively, "Expenses"), to the extent that such Expenses
arise out of or are imposed upon or asserted against such Indemnified Persons
with respect to the creation, operation or termination of the Certificate
Issuer, the execution, delivery or performance of the Declaration of Trust or
the Certificate Indenture, as the case may be, or the transactions contemplated
thereby, the failure of the Note Issuer or any other person (other than the
person being indemnified) to perform its obligations hereunder or under any of
the Basic Documents, or otherwise in connection with the Basic Documents or the
transactions contemplated thereby; provided, however, that the Note Issuer is
not required to indemnify any Indemnified Person for any Expenses that result
from the


                                       2

<PAGE>   4
willful misconduct or gross negligence of such Indemnified Person and provided,
further that it is understood and agreed that the Certificate holders may only
exercise their rights and remedies hereunder through the Certificate Trustee and
no Certificate holder shall have any right to pursue any cause of action to
enforce its rights and remedies hereunder except through the Certificate
Trustee. For purposes of this indemnification, the references to the "Agencies"
shall include the Executive Office of Administration and Finance of The
Commonwealth of Massachusetts. The obligations of the Note Issuer to indemnify
the Indemnified Persons as provided herein shall survive the termination of the
Declaration of Trust, the termination, satisfaction or discharge of the
Certificate Indenture and the resignation or removal of the Delaware Trustee or
the Certificate Trustee. The Indemnified Persons are entitled to the benefit of
this Agreement and shall have the right to enforce the provisions hereof. The
Indemnified Persons shall have a lien against the Transition Property to secure
payment of such Expenses to the extent provided in the Statute or the financing
order issued pursuant thereto. The Note Issuer's obligations to make payments of
such Expenses shall be subject to the priorities set forth in Section 8.02 of
the Note Indenture.

         (b) If the indemnity provided in paragraph (a) of this Section 3 is
unavailable to or insufficient to hold harmless an Indemnified Person for any
reason, the Note Issuer and such Indemnified Person agree to contribute to the
aggregate Expenses to which the Note Issuer and such Indemnified Person may be
subject in such proportion as is appropriate to reflect the relative benefits
received by the Note Issuer and such Indemnified Person, respectively, from the
offering of the Certificates and the Notes; provided, however, that in no case
shall any Indemnified Person be responsible for any amount in excess of the fees
or other amounts received by such Indemnified Person in connection with the
Basic Documents and the issuance of the Notes and the Certificates. If the
allocation provided by the immediately preceding sentence is unavailable for any
reason, the Note Issuer and the Indemnified Person shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Note Issuer and such Indemnified Person, respectively,
in connection with the actions or omissions giving rise to such Expenses as well
as any other relevant equitable considerations; provided, however, that in no
case shall any Indemnified Person be responsible for any amount in excess of the
fees or other amounts received by such Indemnified Person in connection with the
Basic Documents and the issuance of the Notes and the Certificates. The Note
Issuer and the Indemnified Persons agree that it would not be just and equitable
if contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above.

         Section 4. Payment. All amounts owed by the Note Issuer to the
Certificate Trustee, the Delaware Trustee, the Trust, any Authorized Agent or
the Agencies under the Declaration of Trust or the Certificate Indenture, as the
case may be, shall be paid to the Certificate Trustee, the Delaware Trustee, the
Trust, any Authorized Agent or the Agencies, as appropriate, pursuant to the
Declaration of Trust or the Certificate Indenture, as the case may be, or, if a
fee agreement or fee schedule has been provided to the Note Issuer, payment
shall be made in accordance with said agreement or schedule, or if not otherwise
provided, such amount shall be paid directly to the Certificate Trustee, the
Delaware Trustee, the Trust, any Authorized Agent or the Agencies, as
appropriate, until the Note Issuer is otherwise notified by the Certificate
Trustee, the Delaware Trustee, the Trust, such Authorized Agent or such Agency;
provided, however, that

                                       3

<PAGE>   5
notwithstanding anything to the contrary in this Agreement or in any fee
agreement or fee schedule, not later than 30 days following the selection of a
successor Delaware Trustee pursuant to the provisions of Section 4.7 of the
Declaration of Trust, the Note Issuer shall pay to the appropriate parties all
amounts described in this Section 4 which have accrued through the date of
selection of such successor Delaware Trustee; and, provided, further, that
notwithstanding anything to the contrary in this Agreement or in any fee
agreement or fee schedule, each of the parties to this Agreement agrees that the
Note Issuer's obligations to make payments to it shall be subject to the
priorities set forth in Section 8.02 of the Note Indenture and the Note Issuer
shall have no obligation to make any payment except to the extent consistent
with Section 8.02 of the Note Indenture. The Note Issuer hereby irrevocably
directs the Note Trustee to pay such amounts from monies on deposit in the
Collection Account as provided pursuant to Section 8.02 of the Note Indenture.

         Section 5. Notices. Unless otherwise specifically provided herein, all
notices, directions, consents and waivers required under the terms and
provisions of this Agreement shall be in English and in writing, and any such
notice, direction, consent or waiver may be given by United States mail, courier
service, telegram, telex, telemessage, telecopy, telefax, cable or facsimile
(confirmed by telephone or in writing in the case of notice by telegram, telex,
telemessage, telecopy, telefax, cable or facsimile) or any other customary means
of communication, and any such notice, direction, consent or waiver shall be

                             ISSUANCE ADVICE LETTER

                                  July 28, 1999


ADVICE DTE 98-118

DEPARTMENT OF TELECOMMUNICATIONS AND ENERGY (THE "DEPARTMENT") OF THE
COMMONWEALTH OF MASSACHUSETTS

SUBJECT: Issuance Advice Letter for Electric Rate Reduction Bonds ("RRBs")
Pursuant to DTE Docket No. 98-118 (the "Financing Order"), Boston Edison Company
("Boston Edison") hereby transmits for filing, on or about the pricing date of
this series of RRBs, the initial RTC Charge for such series. This Issuance
Advice Letter is for the RRB series Massachusetts RRB Special Purpose Trust
BEC-1 Rate Reduction Certificates classes A-1, A-2, A-3, A-4 and A-5. Any
capitalized terms not defined herein shall have the meanings ascribed thereto in
the Financing Order.

PURPOSE
This filing establishes the following:

(a)      the actual terms of the RRBs being issued;

(b)      confirmation of ratepayer savings;

(c)      the initial RTC Charge for retail users;

(d)      the identification of the Transition Property to be sold to a special
         purpose entity (the "SPE"); and

(e)      the identification of the SPE;

BACKGROUND

In the Financing Order, the Department authorized Boston Edison to file an
Issuance Advice Letter when pricing terms for a series of RRBs have been
established. This Issuance Advice Letter filing incorporates the methodology for
determining the RTC Charge approved and authorized by the Department in the
Financing Order to establish the initial RTC Charge for a series of RRBs and
establishes the initial RTC Charge to be assessed and collected from all classes
of retail users of Boston Edison's distribution system within the geographic
service territory as in effect on July 1, 1997, whether or not energy is
purchased from Boston Edison or any TPS, and whether or not such distribution
system is being operated by Boston Edison or a successor distribution company.
The RTC Charge is a portion, which may become all, of the transition charge
approved by the Department. The RTC Charge is a usage-based component of the
transition charge on each retail user's monthly bill, and may include in the
future a component of any exit fee collected pursuant to M.G.L. c. 164, Section
1G(g) until the Total RRB Payment Requirements are discharged in full.
