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


Ladies and Gentlemen:

     1.  INTRODUCTION.  Illinois Power Securitization Limited Liability Company,
a special purpose Delaware limited liability company (the "Grantee") proposes to
cause and be sold to the underwriters named in Schedule II hereto (the
"Underwriters"), for whom you are acting as representatives (the
"Representatives"), the principal amount of the notes identified in Schedule I
hereto (the "Notes") to be issued.   If the firm or firms listed in Schedule II
hereto include only the firm or firms listed in Schedule I hereto, then the
terms "Underwriters" and "Representatives," as used herein, shall each be deemed
to refer to such firm or firms.

     Illinois Power Special Purpose Trust, a Delaware business trust (the "Note
Issuer") was formed pursuant to a declaration of trust, dated as of December 1,
1998,  by First Union Trust Company, National Association, a national banking
association, as Delaware Trustee (the "Delaware Trustee"), and Cynthia G.
Steward and Eric B. Weekes, each as a Beneficiary Trustee (the "Trust
Agreement"), and the Notes will be issued pursuant to an indenture, dated as of
December 1, 1998, as supplemented by a first supplemental indenture or Trust
Issuance Certificate (and as amended and supplemented from time to time, the
"Indenture"), by and between the Note Issuer and Harris Trust and Savings Bank,
a banking corporation organized under the laws of the State of Illinois, as
Indenture Trustee (the "Indenture Trustee").  The assets of the Note Issuer will
consist primarily of the Intangible Transition Property (whether created by the
Transitional Funding Order issued by the Illinois Commerce Commission (the
"ICC") on September 10, 1998 (the "1998 Funding Order") or any Subsequent
Funding Order) transferred 

<PAGE>

to the Note Issuer pursuant to the Sale Agreement (as hereinafter defined).  
Such Intangible Transition Property was, by virtue of the 1998 Funding Order, 
granted to and vested in the Grantee, whose sole member is Illinois Power 
Company (the "Company").  Pursuant to an agreement relating to the grant of 
Intangible Transition Property, dated as of December 1, 1998 (the "Grant 
Agreement"), by and between the Company and the Grantee, the Company has 
confirmed the absolute nature of the ownership of the Intangible Transition 
Property in the Grantee.  The Intangible Transition Property will be 
transferred to the Note Issuer by the Grantee pursuant to an Intangible 
Transition Property sale agreement, dated as of December 1, 1998 (the "Sale 
Agreement"), by and between the Grantee and the Note Issuer.  Other 
Intangible Transition Property may be granted to and vested in the Grantee 
pursuant to Subsequent Financing Orders and confirmed by Subsequent Grant 
Agreements and transferred to the Note Issuer by the Grantee pursuant to 
Subsequent Sale Agreements.  Pursuant to the Indenture, the Note Issuer has 
granted to the Indenture Trustee, as trustee for the benefit of the holders 
of the Notes, all of its right, title and interest in and to the Intangible 
Transition Property as security for the Notes.  The Intangible Transition 
Property will be serviced pursuant to an Intangible Transition Property 
servicing agreement, dated as of December 1, 1998 (as amended and 
supplemented from time to time, the "Servicing Agreement"), by and between 
the Company, as servicer, and the Grantee.  All of the Grantee's right, title 
and interest in and to the Grant Agreement, the Sale Agreement and the 
Servicing Agreement, among other things, will be transferred to the Note 
Issuer as Related Assets pursuant to the Sale Agreement.

     Capitalized terms used and not otherwise defined herein shall have the
meanings given to them in the Indenture, including Appendix A thereto.

     2.  REPRESENTATIONS AND WARRANTIES.  Each of the Company and the Grantee
represents and warrants to, and agrees with, each Underwriter as set forth below
in this Section 2.  Certain terms used in this Section 2 are defined in
paragraph (c) hereof.

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

                   (i)    The Grantee and the Notes meet the requirements for
            the use of Form S-3 under the Securities Act of 1933 (the "Act"),
            and the Grantee has filed with the Securities and Exchange
            Commission (the "SEC") a registration statement (the file number of
            which is set forth in Schedule I hereto) on such Form, including a
            basic prospectus, for registration under the Act of the offering and
            sale of the Notes.  The Grantee 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, has become effective. 
            The offering of the Notes is a Delayed Offering and, although the
            Basic Prospectus may not include all the information with respect to
            the Notes and the offering thereof required by the Act and the rules
            thereunder to be included in the Final Prospectus, the Basic

            information required by the Act and the rules thereunder to be 
            included therein as of the Effective Date. The Grantee 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 Notes and the offering 
            thereof.  As filed, such final prospectus supplement shall 
            include all required information with respect to the Notes 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

            has advised you, prior to the Execution Time, will be included or 
            made therein.

                   (ii)   The Grantee and the Notes meet the requirements for 
            the use of Form S-3 under the Act and the Grantee has filed with 
            the SEC a registration statement (the file number of which is set 
            forth in Schedule I hereto) on such Form, including a basic 
            prospectus, for registration under the Act of the offering and 
            sale of the Notes.  The Grantee 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 Notes 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 Grantee 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 Notes 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 Notes 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 Grantee has advised you, prior to the 
            Execution Time, will be included or made therein.

     registration statement at the effective date thereof.  A "Delayed 
     Offering" shall mean an offering of securities 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 securities so offered.  
     Whether the offering of the Notes is a Non-Delayed Offering or a Delayed 
     Offering shall be set forth in Schedule I hereto.

     reference in the Prospectus present fairly the financial position and
     results of operations of the Grantee and the Note Issuer, respectively, as
     of the respective dates and for the respective periods specified and,
     except as otherwise stated in the Prospectus, such financial statements
     have been prepared in conformity with generally accepted accounting
     principles applied on a consistent basis during the periods involved.

     perform its obligations under this Agreement, the Sale Agreement, the
     Indenture and the Notes.

            (g)    The Note Issuer is not in violation of the Trust Agreement,

     condition contained in any material contract, lease, note or other 
     instrument to which it is a party or by which it may be bound, or 
     materially in violation of any law, administrative regulation or 
     administrative, arbitration or court order, except in each case to such 
     extent as may be set forth in the Prospectus; and the execution and 
     delivery of the Sale Agreement, and the Indenture and the Notes, the 
     incurrence of the obligations set forth therein and the consummation of 
     the transaction therein contemplated will not conflict with or 
     constitute a breach of, or default under, the Trust Agreement or any 
     mortgage, contract, lease, note or other instrument to which the Note 
     Issuer is a party or by which it may be bound, or any law, 
     administrative regulation or administrative, arbitration or court order.

            (h)    There is no pending or threatened suit or proceeding before
     any court or governmental agency, authority or body or any arbitration
     involving the Company or any of its significant subsidiaries or the Note
     Issuer required to be disclosed in the Prospectus which is not adequately
     disclosed in the Prospectus.

     necessary action and duly qualified under the Trust Indenture Act; and the
     Indenture has been duly and validly executed and delivered and is a valid
     and enforceable instrument in accordance with its terms (subject to

     terms of this Agreement have been duly and validly authorized by the
     necessary action; the Notes, when duly executed, authenticated and
     delivered against payment of the agreed consideration therefor, will be
     valid and enforceable obligations in accordance with their terms, entitled
     to the benefits provided by the Indenture, and the holders of the Notes
     will be entitled to the payment of principal and interest as therein
     provided; and the Notes and the Indenture conform to the descriptions
     thereof contained in the Prospectus.

     Any certificate signed by any officer of the Company or the Grantee and

being herein called the "Closing Date").  Delivery of the Notes shall be made 
to the Representatives for the respective accounts of the several 
Underwriters against payment by the several Underwriters through the

     5.  COVENANTS.  

            (a)    COVENANTS OF THE GRANTEE.  The Grantee covenants and agrees
     with the several Underwriters that:

                   (i)    The Grantee will use commercially reasonable 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 Notes, the Grantee
            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 Grantee 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 Grantee will cause
            the Final Prospectus, properly completed, 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 Grantee will promptly advise the Representatives (i) when the
            Registration 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 Notes, 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 Grantee of any notification with
            respect to the suspension of the qualification of 

                                      7

<PAGE>

            the Notes for sale in any jurisdiction or the initiation or 
            threatening of any proceeding for such purpose.  The Grantee will 
            use commercially reasonable 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
            Notes 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 Grantee
            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 Grantee will cause Note
            Issuer to make generally available to the Noteholders and to the
            Representatives an earnings statement or statements of the Note
            Issuer which will satisfy the provisions of Section 11(a) of the Act
            and Rule 158 under the Act.

                   (iv)   The Grantee 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 Grantee 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 Grantee
            will pay the expenses of printing or other production of all
            documents relating to the offering.

                   (v)    The Grantee will arrange for the qualification of the
            Notes for sale under the laws of such jurisdictions as the
            Representatives may designate, will maintain such qualifications in
            effect so long as required for the distribution of the Notes and
            will arrange for the determination of the legality of the Notes for
            purchase by institutional investors; provided that in no event shall
            the Grantee 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 Notes, in any
            jurisdiction where it is not now so subject.

                   (vi)   Until the business date set forth on Schedule I
            hereto, the Grantee will not, without the consent of the
            Representatives, offer, sell or contract to sell, 

                                      8

<PAGE>

            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).

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

                   (viii) So long as any of the Notes are outstanding, the
            Grantee will furnish to the Representatives, to the extent not
            provided by the Company pursuant to clause (b)(iii) below, (i) as
            soon as available, a copy of each report of the Grantee or the Note
            Issuer filed with the SEC under the Exchange Act, or mailed to
            Noteholders, (ii) a copy of any filings made by the Grantee or the
            Note Issuer with the ICC pursuant to the 1998 Funding Order, and
            (iii) from time to time, any information concerning the Company, the
            Grantee, the Note Issuer, 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(m) of this Agreement is
            conditioned upon the furnishing of documents or the taking of other
            actions by the Grantee on or after the Closing Date, the Grantee
            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 commercially reasonable efforts
            to cause the Registration Statement, if not effective at the
            Execution Time, and any amendment thereto, to become effective.  The
            Company will use commercially reasonable efforts to prevent the
            issuance 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 apply the proceeds of the issuance
            and sale of the Notes for the purposes described in the Prospectus.

                   (iii)  Until the business date set forth on Schedule I
            hereto, the Company will not, without the consent of the
            Representatives, offer, sell or contract to sell, or otherwise
            dispose of, directly or indirectly, or announce the offering of, any

                                      9

<PAGE>

            asset-backed securities of a trust or other special purpose vehicle
            (other than the Notes).

                   (iv)   So long as any of the Notes 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 Company, the Grantee or the Note Issuer filed with the SEC under
            the Exchange Act, or mailed to Noteholders, (ii) a copy of any
            filings with the ICC by the Company, the Grantee or the Note Issuer
            pursuant to the 1998 Funding Order, and (iii) from time to time, any
            information concerning the Company, the Grantee or the Note Issuer,
            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(m) 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)   The Company recognizes and agrees that a substantial
            impairment of the rights of Holders with respect to the collection
            of IFCs and payments on the Notes, arising from a declaration of
            invalidity of the Amendatory Act and/or the Funding Law or for any
            other reason, occurring after the Company and its affiliates
            received the proceeds of such Notes, would not be equitable.  The
            Company agrees to take any and all actions reasonably necessary to
            preserve the rights of Holders with respect to payments on the Notes
            out of the amounts represented by IFCs or their equivalent,
            including, but not limited to, (i) making appropriate filings with
            the State of Illinois, the ICC or other regulatory bodies to defend,
            preserve and create on behalf of Holders the right to receive
            payments as provided in the Notes and (ii) so long as the 1998
            Funding Order remains in effect, continuing to deduct and pay over
            to the Servicer for the benefit of the Note issuer all IFCs and IFC
            Payments or equivalent revenues received by the Company
            notwithstanding any declaration of invalidity of the Amendatory Act
            and/or the Funding Law.

                   (vii)  The Initial IFC Tariff will be calculated in
            accordance with the 1998 Funding Order.

            (g)    The Representatives shall have received a certificate of the
     Grantee, signed by the Sole Member or any Manager of the Grantee, including
     the Independent Managers of the Grantee, dated the Closing Date, to the
     effect that the signers of such certificate have carefully examined the
     Registration Statement, the Final Prospectus, any supplement to the Final
     Prospectus and this Agreement and that:

                   (i)    the representations and warranties of the Grantee in
            this Agreement and in the Sale Agreement are true and correct in all
            material respects on and as of the Closing Date with the same effect
            as if made on the Closing Date, and the Grantee and the Note Issuer
            have complied with all the agreements and satisfied all the
            conditions on each of their part to be performed or satisfied at or
            prior to the Closing Date;

                   (ii)   no stop order suspending the effectiveness of the
            Registration Statement has been issued and no proceedings for that
            purpose have been 

                                      12

<PAGE>

            instituted or, to the Grantee's knowledge, threatened; and

                   (iii)  since the dates as of which information is given in
            the Final Prospectus (exclusive of any supplement thereto), there
            has been no material adverse change in (A) the condition (financial
            or other), prospects, earnings, business or properties of the
            Grantee or the Note Issuer, whether or not arising from transactions
            contemplated by the Final Prospectus in the ordinary course of
            business, or (B) the Intangible Transition Property or any right
            related thereto under the Funding Law or the 1998 Funding Order,
            except as set forth in or contemplated in the Final Prospectus
            (exclusive of any supplement thereto).

            (h)    The Representatives shall have received a certificate of the
     Company, signed by the Chief Executive Officer, the President or a
     Vice-President and the principal financial or accounting officer of the
     Company, dated the Closing Date, to the effect that the signers of such
     certificate have carefully examined the Registration Statement, the Final
     Prospectus, any supplement to the Final Prospectus and this Agreement and
     that:

                   (i)    the representations and warranties of the Company in
            this Agreement, the Grant Agreement, the Servicing Agreement, the
            Administration Agreement and the Remediation Agreement are true and
            correct in all material respects on and as of the Closing Date with
            the same effect as if made on the Closing Date, and the Company has
            complied in all material respects with all the agreements and
            satisfied all the conditions on its part to be performed or
            satisfied at or prior to the Closing Date; provided, however, that
            the execution of each certificate by any of said individuals on
            behalf of the Company shall not be deemed to be the expression of
            any legal opinion or opinions by any of said individuals;

                   (ii)   no stop order suspending the effectiveness of the
            Registration Statement has been issued and no proceedings for that
            purpose have been instituted or, to the Company's knowledge,
            threatened; and

                   (iii)  since the dates as of which information is given in
            the Final Prospectus (exclusive of any supplement thereto), there
            has been no material adverse change in (A) the condition (financial
            or other), prospects, earnings, business or properties of the
            Company and its subsidiaries taken as a whole, whether or not
            arising from transactions contemplated by the Final Prospectus or in
            the ordinary course of business, or (B) the Intangible Transition
            Property, except as set forth in or contemplated in the Final
            Prospectus (exclusive of any supplement thereto).

            (i)    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 

                                      13

<PAGE>

     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 its subsidiaries) 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 Intangible Transition 
     Property," "The Servicer" and "Description of the Notes" in the Final 
     Prospectus, agrees with the accounting records of the Company and its 
     subsidiaries, 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(9) of the Indenture.

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

     In addition, except as provided in Schedule I hereto, at the Execution
Time, PricewaterhouseCoopers LLP shall have furnished to the Representatives a
letter or letters, dated as of the Execution Time, in form and substance
satisfactory to the Representatives, to the effect set forth above. 

            (j)    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, the Grantee or
     the Note Issuer, or (ii) the Intangible Transition Property, the Notes, the
     1998 Funding Order or the Funding Law, the effect of which is, in the case
     of either (i) or (ii) above, 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 as contemplated by the
     Registration Statement (exclusive of any amendment thereof) and the Final
     Prospectus (exclusive of any supplement thereto).

            (k)    The Representatives shall have received on the Closing Date
     an opinion letter or letters, portions of which may be delivered by Schiff
     Hardin & Waite, counsel to the Company, the Grantee and the Note Issuer,
     and portions of which may be delivered by Richards, Layton & Finger, P.A.,
     special Delaware counsel to the Grantee and the Note Issuer, dated the
     Closing Date, in form and substance reasonably satisfactory to the
     Representatives, but subject to the qualifications, limitations,
     assumptions and analyses set forth therein (i) to the effect that a
     bankruptcy court would conclude that, if the Company is deemed to have
     received some interest in the Intangible Transition Property, that interest
     was transferred by the Company to the Grantee as an absolute transfer (as
     in a true sale), and no interest in or title to the Intangible Transition
     Property shall be part of 

                                      14

<PAGE>

     the Company's estate in the event of a bankruptcy petition by or against 
     the Company under the Bankruptcy Code; (ii) to the effect that a court 
     would not order the substantive consolidation of the assets and 
     liabilities of the Grantee with those of the Company in the event of a 
     bankruptcy, reorganization or other insolvency proceeding involving the 
     Company; (iii) to the effect a federal bankruptcy court or another 
     federal court would hold that Delaware law (and not United States 
     federal law) governs the determination of whether a voluntary bankruptcy 
     petition filed on behalf of the Grantee has been duly authorized; (iv) 
     to the effect that if properly presented to a Delaware court, a Delaware 
     court applying Delaware law would conclude that (A) pursuant to Section 
     2.7(b) of the Operating Agreement of the Grantee, in order for a person 
     to initiate any Event of Bankruptcy (as defined in the Operating 
     Agreement) with respect to the Grantee or take any action in furtherance 
     of any such Event of Bankruptcy, the affirmative vote of all of the 
     Managers (including the Independent Managers (as defined in the 
     Operating Agreement)) is required, and (B) such provision, contained in 
     Section 2.7(b) of the Operating Agreement, that requires the affirmative 
     vote of all of the Managers (including the Independent Managers), 
     constitutes a legal, valid and binding agreement of the Sole Member and 
     is enforceable against the Sole Member, in accordance with its terms; 
     and (v) the Operating 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.

            (l)    The Representatives shall have received on the Closing Date
     an opinion letter or letters of Schiff Hardin & Waite, counsel to the
     Company, the Grantee and the Note Issuer, dated the Closing Date, in form
     and substance reasonably satisfactory to the Representatives, to the effect
     that, but subject to the qualifications, limitations, assumptions and
     analysis therein set forth, including the assumption that any Impairment
     (as defined therein) would be substantial, a reviewing court, in a properly
     prepared and presented case: (i)  would conclude that, absent a
     demonstration by the State of Illinois (the "State") that an Impairment is
     necessary to further a significant and legitimate public purpose, the
     Noteholders (or the Indenture Trustee acting on their behalf) could
     challenge successfully under Article I, Section 10 of the United States
     Constitution  (the "Contract Clause") the constitutionality of any law
     passed by the State legislature determined by such court to limit, alter,
     impair or reduce the value of the Intangible Transition Property or the
     Charges (as defined therein) so as to cause an Impairment prior to the time
     that the Notes are fully paid and discharged; (ii) would conclude that any
     attempt by citizens of the State to initiate changes to the Amendatory Act
     determined by such court to limit, alter, impair or reduce the value of the
     Intangible Transition Property or the Charges would be invalid; (iii) would
     conclude that under the Funding Law the ICC would be prohibited from taking
     any action subsequent to the 1998 Funding Order becoming final determined
     by such court to reduce, postpone, impair or terminate the value of the
     Intangible Transition Property or the Charges; (iv) should conclude that
     permanent injunctive relief is available, pursuant to the Contract Clause,
     to prevent implementation of legislation hereafter passed by the Illinois
     legislature determined by such court to limit, alter, impair or reduce the
     value of the Intangible Transition Property or the Charges so as 

                                      15

<PAGE>

     to cause an Impairment; and although sound and substantial arguments 
     support the granting of preliminary injunctive relief, the decision to 
     do so will be in the discretion of the court requested to take such 
     action, which will be exercised on the basis of the considerations 
     discussed in such opinion; (v) in the event that a provision of the 
     Amendatory Act were hereafter declared to be invalid by a court, a 
     reviewing court should hold that the Intangible Transition Property 
     would remain valid and vested in the Grantee or its assignees and the 
     Noteholders would continue to be secured thereby; (vi) if a reviewing 
     court were to determine, after such a declaration, that the Intangible 
     Transition Property would remain valid and so vested and that the 
     Noteholders would continue to be secured thereby, such court should also 
     determine, for the same reasons, that the substance of the State Pledge 
     would continue in effect for the benefit of the Noteholders; (vii) a 
     reviewing court which determines that the substance of the State Pledge 
     continues in effect for the benefit of the Noteholders should also 
     determine, for the same reasons, that the ICC could not take any action 
     determined by such court to limit, alter, impair or reduce materially 
     the value of the Intangible Transition Property or the Charges, except 
     for such actions, if any, which could be taken by the State without 
     violating the State Pledge; and (viii) notwithstanding a judicial 
     declaration of the invalidity of the Amendatory Act, the 1998 Funding 
     Order would remain in effect and the Intangible Transition Property 
     would continue to be valid and enforceable, at least against the Company 
     and its successors and assigns (including a trustee in bankruptcy), 
     unless and until the 1998 Funding Order were modified by the ICC or a 
     court in subsequent proceedings initiated to vacate, amend or otherwise 
     modify the 1998 Funding Order; however, notwithstanding such a 
     declaration, it would be possible to seek a stay of any decision which 
     vacates, amends or otherwise modifies the 1998 Funding Order in a manner 
     adversely affecting the payment of the Charges pending appellate review 
     of such decision; and while sound and substantial arguments support the 
     granting of such a stay, the decision to do so will be in the discretion 
     of the court requested to take such an action, which will be exercised 
     on the basis of the factors discussed in such opinion.

            (m)    The Notes shall have been rated in the highest long-term
     rating category by each of the Rating Agencies and on or after the date
     hereof (i) no downgrade shall have occurred in the rating accorded to the
     debt securities of the Company by any Rating Agency, and (ii) no such
     organization shall have publicly announced that it has under surveillance
     or review, with possible negative implications, its rating of any of the
     Company's debt securities.

            (n)    On or prior to the Closing Date, the Grantee shall have
     delivered to the Representatives evidence, in form and substance reasonably
     satisfactory to the Representatives, of compliance with Section 2.10 of the
     Indenture, together with such reliance letters as the Representatives shall
     request.

            (o)    On or prior to the Closing Date, the Grantee shall have
     delivered to the Representatives evidence, in form and substance reasonably
     satisfactory to the Representatives, that appropriate filings have been,
     are being or will be made, as 

                                      16

<PAGE>

     applicable, pursuant to Section 3.08 of the Sale Agreement and in 
     accordance with the Funding Law and other applicable law reflecting the 
     Note Issuer's first priority perfected ownership interest in the 
     Intangible Transition Property.

            (p)    On or prior to the Closing Date, the Grantee shall have
     delivered to the Representatives evidence, in form and substance reasonably
     satisfactory to the Representatives, that appropriate filings have been,
     are being or will be made, as applicable, pursuant to Section 18-104(h) of
     the Funding Law.

            (q)    The Representatives shall have received an opinion, or
     reliance letter thereon, from Mayer Brown & Platt, tax counsel to the Note
     Issuer, substantially in the form of Exhibit 8.1 to the Registration
     Statement.  

            (r)    Prior to the Closing Date, the Company, the Grantee and the
     Note Issuer 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 Grantee and the Note Issuer in writing
or by telephone or telegraph confirmed in writing.

     The documents required to be delivered by this Section 6 shall be delivered
at the offices of Schiff Hardin & Waite, 7200 Sears Tower, Chicago, Illinois, on
the Closing Date.

     7.  EXPENSES.

            (a)    The Company and the Grantee will pay, or cause to be paid,
     all expenses incident to the performance of their respective obligations
     and those of the Note Issuer under this Agreement, including without
     limitation, (i) expenses incident to the word processing, printing,
     reproduction and distribution of the registration statement as originally
     filed with the SEC and each amendment thereto, Preliminary Final
     Prospectuses and the Final Prospectus (including any amendments and
     supplements thereto), (ii) the fees and disbursements of the Indenture
     Trustee, the Delaware Trustee, the Beneficiary Trustees and their
     respective counsel, (iii) the fees and disbursements of counsel to the
     Company, the Grantee, the Note Issuer, and  the independent public
     accountants of the Company, the Grantee and the Note Issuer, (iv) the fees
     charged by the Rating Agencies in connection with the rating of the Notes,
     (v) the fees of DTC in connection with the book-entry registration of the
     Notes, and (vi) expenses incurred in distributing Preliminary Final
     Prospectuses and the Final Prospectus (including any amendments and
     supplements thereto) by the Underwriters.  The Company and the 

                                      17

<PAGE>

     Grantee will also pay all reasonable fees and disbursements of 
     Underwriters' counsel, and will reimburse the Underwriters for any 
     expenses  incurred by the Underwriters pursuant to Section 5(a)(v) 
     hereof in connection with the qualification of the Notes for sale under 
     the laws of such jurisdictions in the United States as the 
     Representatives may designate, together with costs and expenses in 
     connection with any filing with the National Association of Securities 
     Dealers with respect with the transactions contemplated hereby.

            (b)    If the sale of the Notes 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 Grantee or the Note Issuer 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 Grantee 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 them in connection with the proposed purchase and sale of
     the Notes.

     8.  INDEMNIFICATION AND CONTRIBUTION.

            (a)    The Company and the Grantee will, jointly and severally,
     indemnify and hold harmless each Underwriter, the directors, officers,
     members, employees and agents of each Underwriter, and each person who
     controls any Underwriter 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
     Funding Law, 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, directly or indirectly, (i) the complete or partial judicial
     invalidation of the Amendatory Act and/or the Funding Law, or (ii) 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 Notes as originally filed or in any amendment thereof,
     or in the Basic Prospectus, any 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
     Grantee 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 Grantee or the Company by or on behalf of any Underwriter
     through the Representatives specifically for inclusion therein; 

                                      18

<PAGE>

     provided further, that, in the case of any indemnification under clause 
     (ii) above, with respect to any untrue statement or omission of material 
     fact made in any Preliminary Final Prospectus, the indemnity agreement 
     contained in this Section 8(a) shall not inure to the benefit of any 
     Underwriter or any person controlling such Underwriter from whom the 
     person asserting any such loss, claim, damage or liability purchased the 
     Notes that are the subject thereof, to the extent that any such loss, 
     claim, damage or liability of such Underwriter occurs under the 
     circumstance where it shall have been determined by a court of competent 
     jurisdiction by final and nonappealable judgment that (A) the Company or 
     the Grantee had previously furnished copies of the Final Prospectus to 
     the Representatives, (B) delivery of the Final Prospectus was required 
     by the Act to be made to such person, (C) the untrue statement or 
     omission of a material fact contained in the Preliminary Final 
     Prospectus was corrected in the Final Prospectus and (D) there was not 
     sent or given to such person, at or prior to the written confirmation of 
     the sale of such Notes to such person, a copy of the Final Prospectus.  
     This indemnity agreement will be in addition to any liability which the 
     Company and the Grantee may otherwise have.

            (b)    Each Underwriter severally agrees to indemnify and hold
     harmless the Company and the Grantee, each of their directors, each of
     their officers who signs the Registration Statement, and each person who
     controls the Company or the Grantee within the meaning of either the Act or
     the Exchange Act, to the same extent as the foregoing indemnity from the
     Company and the Grantee to each Underwriter, but only with reference to
     written information relating to such Underwriter furnished to the Grantee
     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 Grantee and
     the Company 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 

                                      19

<PAGE>

     indemnifying party shall not thereafter be responsible for the fees and 
     expenses of any 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 partes 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.  It is 
     understood that the indemnifying party shall not, in connection with any 
     proceeding or related proceedings in the same jurisdiction, be liable 
     for the reasonable fees and expenses of more than one separate firm for 
     all such indemnified parties.  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 (i) 
     includes an unconditional release of each indemnified party from all 
     liability arising out of such claim, action, suit or proceeding and (ii) 
     does not include a statement as to or an admission of fault, culpability 
     or failure to act, by or on behalf of any indemnified party.  The 
     indemnifying party shall not be liable for any settlement of any 
     proceeding effected without its written consent, which consent shall not 
     be unreasonably withheld.

            (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 Grantee 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 Grantee and one or more of the Underwriters may be subject in
     such proportion as is appropriate to reflect the relative benefits received
     by the Grantee and by the Underwriters from the offering of 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 Notes) be responsible for any amount in excess of the underwriting
     discount or commission applicable to the Notes purchased by such
     Underwriter hereunder.  If the allocation provided by the immediately
     preceding sentence is unavailable for any reason, the Company, the Grantee
     and the Underwriters shall 

                                      20

<PAGE>

     contribute in such proportion as is appropriate to reflect not only such 
     relative benefits but also the relative fault of the Company, the 
     Grantee and the Underwriters respectively in connection with the 
     statements or omissions which resulted in such Losses as well as any 
     other relevant equitable considerations.  Benefits received by the 
     Grantee shall be deemed to be equal to the total net proceeds from the 
     offering (before deducting expenses) of the Notes (which shall be equal 
     to the net proceeds from the sale of the Notes to the Note Issuer 
     (before deducting expenses)), and benefits received by the Underwriters 
     shall be 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 or the Grantee, or the Underwriters, as the case may be.  
     The Company, the Grantee 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 (d), 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 Grantee or the Company 
     within the meaning of either the Act or the Exchange Act, each officer 
     of the Grantee or the Company who shall have signed the Registration 
     Statement and each director of the Grantee or the Company shall have the 
     same rights to contribution as the Grantee or the Company, subject in 
     each case to the applicable terms and conditions of this paragraph (d). 
     The Underwriters' obligations in this paragraph (d) 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 Notes agreed to be purchased by such
Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the nondefaulting Underwriters shall be obligated severally to take
up and pay for (in the respective proportions which the amount of Notes set
forth opposite their names in Schedule II hereto bears to the aggregate amount
of Notes set forth opposite the names of all the remaining Underwriters) the
Notes which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate amount of
Notes which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Notes 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 Notes, and if such
nondefaulting Underwriters do not purchase all the Notes, this Agreement will
terminate without liability to any nondefaulting Underwriter, the Grantee 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 

                                      21


<PAGE>

and the Final Prospectus or in any other documents or arrangements may be 
effected.  Nothing contained in this Agreement shall relieve any defaulting 
Underwriter of its liability, if any, to the Grantee and the Company and any 
nondefaulting Underwriter for damages occasioned by its default hereunder.

     10.  TERMINATION.  This Agreement shall be subject to termination in the
absolute discretion of the Representatives, by notice given to the Company and
the Grantee prior to delivery of and payment for the Notes, if prior to such
time (i) there shall have occurred any change, or any development involving a
prospective change, in or affecting either (A) the business, properties or
financial condition of the Grantee or the Company or (B) the Intangible
Transition Property, the Notes, the 1998 Funding Order or the Funding Law, the
effect of which, in the judgment of the Representatives, materially impairs the
investment quality of the Notes or makes it impractical or inadvisable to market
the Notes, (ii) trading in the Company's Common Stock shall have been suspended
by the SEC or the New York Stock Exchange or trading in securities generally on
the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (iii) a banking moratorium
shall have been declared either by federal, New York State or Illinois State
authorities or (iv) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war or
other calamity or crisis 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 Notes as contemplated by the Final
Prospectus (exclusive of any supplement thereto).

     11.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective agreements,
representations, warranties, indemnities and other statements of the Company or
its officers, the Grantee or its officers, the Note Issuer or its officers and
of the Underwriters set forth in or made pursuant to this Agreement will remain
in full force and effect, regardless of any investigation made by or on behalf
of any Underwriter or of the Company, the Grantee, the Note Issuer or any of the
officers, directors or controlling persons referred to in Section 8 hereof, and
will survive delivery of and payment for the Notes.  The provisions of Sections
7 and 8 hereof shall survive the termination or cancellation of this Agreement
and the complete or partial judicial invalidation of the Amendatory Act and/or
the Funding Law.

     12.  NOTICES.  All communications hereunder will be in writing and may be
given by United States mail, courier service, telegram, telex, telemessage,
telecopy, telefax, cable or facsimile (confirmed by telephone or in writing in

communication shall be effective when delivered, or if mailed, three days after
deposit in the United States mail with proper postage for ordinary mail prepaid,
and if sent to the Representatives, to them at the address specified in Schedule
I hereto; and if sent to the Company, to it at Illinois Power Company, the sole

parties hereto, by notice to the others, may designate additional or

other person will have any right or obligation hereunder.

     14.  APPLICABLE LAW.  This Agreement will be governed by and construed in
accordance with the laws of the State of New York.

     15.  COUNTERPARTS.  This Agreement may be signed in any number of

                                  December 22, 1998




MERRILL LYNCH & CO. 
Merrill Lynch, Pierce, Fenner & Smith, Incorporated,
  as Representative of the Underwriters
New York, New York  

Ladies and Gentlemen:

          We address this letter to you individually and as Representatives 
of the Underwriters (the "Underwriters") named in Schedule II to the 
Underwriting Agreement dated December 10, 1998 (the "Underwriting Agreement") 
among you, Illinois Power Company, an Illinois corporation ("Illinois 
Power"), and Illinois Power Securitization Limited Liability Company, a 
Delaware limited liability company (the "Grantee").  The Underwriting 
Agreement provides for the sale on the date hereof by Illinois Power Special 
Purpose Trust, a Delaware business trust (the "Note Issuer"), to the 
Underwriters of $864,000,000 aggregate principal amount of Illinois Power 
Transitional Funding Trust Notes, Series 1998-1 (the "Notes").  This letter 
is delivered pursuant to Section 6(b) of the Underwriting Agreement.  
Capitalized terms not defined herein have the meanings specified in the 
Underwriting Agreement.

          We have acted as special counsel to Illinois Power, the Grantee and 
the Note Issuer (Illinois Power, the Note Issuer and the Grantee are referred 
to collectively as the "Companies") in connection with the issuance and sale 
of the Notes and the following related matters: (a) the 1998 Funding Order 
issued by the Illinois Commerce Commission (the "ICC") dated September 10, 
1998 in Docket No. 98-0488 creating the Intangible Transition Property and 
granting the same to the Grantee; (b) the Agreement Relating to Grant of 
Intangible Transition Property dated as of December 1, 1998 between Illinois 
Power and the Grantee (the "Grant Agreement"); (c) the Intangible Transition 
Property Sale Agreement dated as of December 1, 1998 (the "Sale Agreement") 
between the Note Issuer and the Grantee; (d) the Indenture dated as of

"Administration Agreement") among Illinois Power, as Administrator and the 
Grantee; (g) the Intangible Transition Property Servicing Agreement dated as

(the "Reconciliation Agreement"). The Grant Agreement, the Sale Agreement, 
the Indenture, the Certificate, the Remediation Agreement, the Administration 
Agreement and the Servicing Agreement are sometimes collectively referred to 
herein as the "Relevant Documents."

          We have also participated with officers and representatives of
Illinois Power, the Grantee and the Note Issuer, including independent public
accountants, other counsel and representatives of the Underwriters in the
preparation of the Registration Statement on Form S-3 (Registration No.
333-63537) and Amendments Nos. 1, 2 and 3 thereto, filed on October 27, 1998,
December 4, 1998 and December 9, 1998, respectively, with the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Securities Act"), which registration statement, as so amended,
became effective on December 10, 1998.  Such registration statement, as so
amended, at the time it became effective (including the documents then
incorporated by reference therein) is hereinafter referred to as the
"Registration Statement".  The prospectus forming a part of the Registration
Statement (including the documents incorporated by reference therein) is
hereinafter referred to as the "Basic Prospectus".  The Basic Prospectus, as the
same was supplemented to reflect the terms of the offering and sale of the Notes
by a prospectus supplement dated December 10, 1998 filed with the Commission on
December 11, 1998 pursuant to Rule 424(b) under the Securities Act (including
all documents incorporated by reference therein at the date hereof) is
hereinafter referred to as the "Final Prospectus."

          For the purposes of rendering the opinions expressed below we have 
relied, as to questions of fact material such opinions, upon the 
representations made in the Underwriting Agreement and Relevant Documents.  
In addition, we have examined and relied upon the originals, or copies 
certified or otherwise identified to our satisfaction, of such instruments 
and other certificates of public officials, officers and representatives of 
the Companies and such other persons, and we have made such investigations of 
law, as we have deemed appropriate as a basis for such opinions.  In our 
examination, we have assumed, without independent investigation, (i) the 
genuineness of the signatures of and legal capacity of all persons signing 
all such instruments and certificates, (ii) the authority of all persons 
signing on behalf of the parties thereto, (iii) the due organization, valid 
existence, good standing and authority of all entities signing all such 
instruments and certificates (other than the Companies), (iv) the due 
authorization, execution and delivery of all instruments and certificates by 
all the parties thereto (other than the Companies), (v) the authenticity of 
all documents submitted to us as originals, and (vi) the conformity to 
original documents of all documents submitted to us as certified, conformed, 
or photostatic copies.

          insolvency, moratorium, fraudulent conveyance or other similar laws
          of general applicability relating to or affecting the enforceability
          of creditors' rights and by the effect of general principles of

          thereto, provide a fair and accurate summary of such law or

               (vii)  (A) the lien of the Indenture in favor of the Holders
          of the Notes in the Intangible Transition Property attaches
          automatically; (B) such lien has been perfected in accordance with

          valid and enforceable against Illinois Power, the Grantee, the Note
          Issuer and all third persons,  including judgment lien creditors; 
          (D) such lien ranks prior to any other lien which subsequently
          attaches to the Intangible Transition Property; and (E) there are no
          other liens on the Intangible Transition Property which have
          attached prior to such lien; and

               (viii)  Neither Illinois Power nor the Note Issuer is an
          "investment company" or under the "control" of an "investment
          company" as such terms are defined under the Investment Company Act
          of 1940, as amended.

          In the course of the preparation of the Registration Statement and
the Final Prospectus we have considered the information set forth therein in the
light of the matters required to be set forth therein, and, as noted above, we
have participated in discussions with your representatives and officers and 
representatives of the Companies, including independent public accountants and
other counsel, during the course of which the contents of the Registration
Statement, the Final Prospectus, the documents incorporated by reference in the
Final Prospectus and related matters were discussed.  We have not independently
checked the accuracy or completeness of, or otherwise verified, and accordingly
are not passing upon, and do not assume any responsibility for, the accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Final Prospectus (except to the extent stated in paragraphs
(b)(iii) and the last clause of (c)(i) and (c)(iv) above); and we have relied as
to materially (with respect to non-legal matters), to a large extent, upon the
judgement of officers and representatives of the Companies.  However, as a
result of such consideration and participation, nothing has 

                                      A-8

<PAGE>

come to our attention that causes us to believe that the Registration 
Statement (except for the financial statements and other financial or 
statistical data included or incorporated by reference therein and the Form 
T-1, as to which we have not been asked to comment), at the effective date 
thereof, contained any untrue statement of a material fact or omitted to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading, or that the Final Prospectus (except for 
the operating statistics, financial statements and other financial or 
statistical data contained or incorporated by reference therein and the Form 
T-1, as to which we have not been asked to comment) as of its date contained, 
or as of the date hereof contains, any untrue statement of a material fact or 
omitted or omits to state a material fact necessary to make the statements 
therein, in the light of the circumstances under which they were made, not 
misleading.  

          The foregoing opinions are limited to the laws of Illinois and New
York, the Delaware Limited Liability Company Act and, to the extent specifically
referred to herein, the federal laws of the United States of America. We have,
with your consent, assumed the validity and continued effectiveness of the
Amendatory Act (including, without limitation, the Funding Law and the 1998
Funding Order); provided, however, that our opinion with respect to the
enforceability of the Remediation Agreement against Illinois Power is not so
qualified.  In that regard we refer you to our opinion of even date herewith
delivered pursuant to Section 6(l) of the Underwriting Agreement.  Further, we
have relied, with your consent, on the opinion dated today of Richards, Layton &
Finger delivered pursuant to Section 6(d) of the Underwriting Agreement and on
the opinion of Mayer, Brown & Platt delivered in the form of Exhibit 8.1 to the
Registration Statement.  We express no opinion as to the enforceability of any
provisions of the Grant Agreement or the Servicing Agreement pursuant to which
Illinois Power, the Grantee or the Servicer covenant to continue to deduct and
collect amounts equal to the IFC Charges and equivalent amounts, and to remit
those amounts to the Servicer or the Note Issuer, as the case may be,  if the
Funding Order were no longer in effect.  The opinion expressed in this letter
with respect to the enforceability of indemnification provisions are limited by
principles of public policy limiting their enforceability.  Such principles as
applied by a court might include a requirement that a creditor act reasonably
and in good faith.  In addition, certain remedial provisions of the Relevant
Documents may be unenforceable in whole or in part under the laws of the State
of Illinois, but the inclusion of such provisions does not affect the validity
of any Relevant Document taken as a whole, and the Relevant Documents, taken as
a whole, contain adequate provisions for the practical realization of the rights
and benefits intended to be afforded thereby.

          Any opinion or statement herein which is expressed to be "to our
knowledge" or is otherwise qualified by words of like import means that the
lawyers currently practicing law with this Firm who have had an active
involvement in advising Illinois Power, the Grantee or the Note Issuer with
regard to the authorization issuance and sale of the Notes have no current
conscious awareness of any facts or information contrary to such opinion or
statement; and, except as described above, we have undertaken no independent
investigation with respect to such facts or information.

            INDENTURE dated as of December 1, 1998, between ILLINOIS POWER 
SPECIAL PURPOSE TRUST, a Delaware business trust (the "Note Issuer"), and 
Harris Trust and Savings Bank, a banking corporation organized under the laws 
of the State of Illinois, as trustee (the "Indenture Trustee").

            In consideration of the mutual agreements herein contained, each 
party agrees as follows for the benefit of the other and each of the Holders:

                          RECITALS OF THE NOTE ISSUER

            The Note issuer has duly authorized the execution and delivery of 
this Indenture and the creation and issuance of Notes issuable in Series

in the respective Trust Issuance Certificate or Series Supplement, if any, 
relating to each such Series of Notes.

            The Notes shall be non-recourse obligations and shall be secured 
by and payable solely out of the proceeds of the Intangible Transition 
Property and the other Note Collateral.  If and to the extent that such 
proceeds of Intangible Transition Property and the other Note Collateral are 
insufficient to pay all amounts owing with respect to the Notes, then, except 
as otherwise expressly provided hereunder, the Holders of the Notes shall 
have no Claim in respect of such insufficiency against the Note Issuer, and 
the Holders, by their acceptance of the Notes, waive any such Claim.

            All things necessary to (a) make the Notes, when executed by the 
Note Issuer and authenticated and delivered by the Indenture Trustee 
hereunder and duly issued by the Note Issuer, valid obligations, and (b) make 
this Note Indenture a valid agreement of the Note Issuer, in each case, in 
accordance with their respective terms, have been done.

            NOW, THEREFORE, THIS INDENTURE WITNESSETH:

            That the Note Issuer, in consideration of the premises herein 
contained and of the purchase of the Notes by the Holders and of other good 
and lawful consideration, the receipt and sufficiency of which are hereby 
acknowledged, and to secure, equally and ratably without prejudice, priority 
or distinction, except as specifically otherwise set forth in this Indenture, 
the payment of the Notes, the payment of all other amounts due under or in 
connection with this Indenture and the performance and observance of all of 
the covenants and conditions contained herein or in such Notes, has hereby 
executed and delivered this Indenture and by these presents does hereby 
convey, grant and assign, transfer and pledge, in each case, in and unto the 
Indenture Trustee, its successors and assigns forever, for the benefit of the 
Holders, all and singular the property hereinafter described (hereinafter 
referred to as the "NOTE COLLATERAL"), to wit:

Closing Date, as Indenture Trustee for the benefit of the Holders of the 
Notes from time to time issued and outstanding, all of the Note Issuer's 
right, title and interest in and to (a) the Intangible Transition Property 
created under and pursuant to the 1998 Funding Order, and transferred by the 
Grantee to the Note Issuer pursuant to the Sale Agreement (including, to the 
fullest extent permitted by law, all revenues, collections, claims, rights,

Agreement, (f) the Collection Account, all subaccounts thereof and all 
amounts of cash or investment property on deposit therein or credited thereto 
from time to time, (g) any interest rate exchange agreement which is executed 
in connection with the issuance of Floating Rate Notes, if any, (h) all 
rights to compel the Servicer to file for and obtain adjustments to the IFCs

Order or any Subsequent Funding Order or any Tariff or Subsequent Tariff 
filed in connection therewith, (i) all present and future claims, demands,

with respect to the related Series (together with any interest earnings 
thereon), it being understood that such amounts described in clauses (i) and 
(iii) above shall not be subject to Section 3.17.

            The foregoing Grant is made in trust to secure the payment of

<PAGE>

further particular designations added or incorporated in such title for the

            (5)    the Scheduled Maturity Date;

            (6)    the Final Maturity Date;

            (7)    the Series Issuance Date;

                   Notes and the extent to which Section 2.11 should apply;


                                      5

<PAGE>

            (13)   any redemption provisions applicable to the Notes of such
                   Series and the price or prices at which and the terms and
                   conditions upon which Notes of such Series shall be redeemed
                   or purchased;

            (14)   to the extent applicable, the extent to which payments on the
                   Notes of the related Series are subordinate to or pari passu
                   in right of payment of principal and interest to other Notes;
                   and

            (15)   any other provisions expressing or referring to the terms and
                   conditions upon which the Notes of the applicable Series or
                   Class are to be issued under this Indenture that are not in
                   conflict with the provisions of this Indenture and as to
                   which the Rating Agency Condition is satisfied.

            SECTION 2.03. EXECUTION AUTHENTICATION AND DELIVERY.  The Notes 
shall be executed on behalf of the Note Issuer by any of its Responsible 
Officers. The signature of any such Responsible Officer on the Notes may be 
manual or facsimile.

            Notes bearing the manual or facsimile signature of individuals 
who were at any time Responsible 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 Indenture, the Note Issuer may deliver Notes executed by the 
Note Issuer to the Indenture Trustee pursuant to an Issuer Order for 
authentication; and the Indenture Trustee shall authenticate and deliver such 
Notes as in this Indenture provided and not otherwise.

            No Note shall be entitled to any benefit under this Indenture or 
be valid or obligatory for any purpose, unless there appears on such Note a 
certificate of authentication substantially in the form provided for therein 
executed by the Indenture 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 Indenture 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 
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 


                                      6

<PAGE>

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 Indenture Trustee shall authenticate and deliver in exchange 
therefor a like principal amount of Definitive Notes of authorized 
denominations. Until so delivered in exchange, the Temporary Notes shall in 
all respects be entitled to the same benefits under this Indenture as 
Definitive Notes.

            SECTION 2.05. REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE 
OF NOTES.  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 Indenture 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 Indenture Trustee is appointed by the 
Note Issuer as Note Registrar, the Note Issuer will give the Indenture 
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 Indenture Trustee shall have the right to inspect the Note Register at 
all reasonable times and to obtain copies thereof, and the Indenture Trustee 
shall have the right to rely conclusively 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 Indenture Trustee shall 
authenticate and the Holder shall obtain from the Indenture Trustee, in the 
name of the designated transferee or transferees, one or more new Notes in 
any Minimum Denominations, of the same Series (and, if applicable, Class) and 
aggregate principal amount.

            At the option of the Holder, Notes may be exchanged for other 
Notes in any Minimum Denominations, of the same Series (and, if applicable, 
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 Indenture Trustee shall 
authenticate and the Holder shall obtain from the Indenture Trustee, the 
Notes which the Holder making the exchange is entitled to receive.

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


                                      7

<PAGE>

            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 Indenture 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) such other guarantee program acceptable to the Indenture 
Trustee, and (b) such other documents as the Indenture 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 or Indenture Trustee 
may require payment of a sum sufficient to cover any tax or other 
governmental charge that may be imposed in connection with any registration 
of transfer or exchange of Notes, other than exchanges pursuant to Section 
2.04 or 9.06 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

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 found at any time 
or enforced by any Person, and shall be entitled to all the benefits of this 
Indenture equally and proportionately with any and all other Notes duly

interest at the applicable Note Interest Rate to the extent lawful) to the 
Persons who are Holders on a subsequent Special Record Date, which date shall 
be at least five Business Days prior to the Special Payment Date.  The Note 
Issuer shall fix or cause to be fixed any such Special Record Date and 
Special Payment Date, and, at least 20 days before any such Special Record 
Date, the Note Issuer shall mail to each affected Holder a notice that states 
the Special Record Date, the Special Payment Date and the amount of defaulted 
interest (plus interest on such defaulted interest) to be paid.

registration of transfer, exchange or redemption shall, if surrendered to any 
Person other than the Indenture Trustee, be delivered to the Indenture 
Trustee and shall be promptly canceled by the Indenture Trustee.  The Note

                   selected by, and in form and substance reasonably
                   satisfactory to, Illinois Power) to the effect that, for
                   federal income tax purposes, (i) such issuance of Notes, and

                   result in gross income to the Grantee, the Note Issuer or 
                   Illinois Power and (ii) such issuance will not materially

                   through the Clearing Agency and the Clearing Agency
                   Participants and shall be limited to those established by law
                   and agreements between such Holders and the Clearing Agency
                   and/or the Clearing Agency Participants. Unless and until
                   Definitive Notes are issued pursuant to Section 2.13, the
                   initial Clearing Agency will make book-entry transfers among
                   the Clearing Agency Participants and receive and transmit
                   distributions of principal and interest on the Book-Entry
                   Notes to such Clearing Agency Participants.

            SECTION 2.12. NOTICES TO CLEARING AGENCY.  Unless and until
Definitive Notes shall have been issued to Holders of such Series pursuant to
Section 2.13 or the applicable Trust Issuance Certificate or Series Supplement,
if any, relating to such Notes, whenever notice, payment, or other communication
to the holders of Book-Entry Notes of any Series is required under this
Indenture, the Indenture Trustee, the Servicer and the Paying Agent shall give
all such notices and communications specified herein to be given to Holders of
such Series to the Clearing Agency.

            SECTION 2.13. DEFINITIVE NOTES.  If (i)(A) the Administrator advises
the Indenture Trustee in writing that the Clearing Agency is no longer willing
or able to properly discharge its responsibilities under any Letter of
Representations and (B) the Administrator is unable to locate a qualified
successor Clearing Agency, (ii) the Administrator, at its option, advises the
Indenture Trustee in writing that, with respect to any Series, it elects to
terminate the book-entry system through the Clearing Agency or (iii) after the
occurrence of a Servicer Default, Holders holding Notes aggregating not less
than 50% of the aggregate Outstanding Amount of any Series of Notes maintained
as Book-Entry Notes advise the Indenture Trustee, the Administrator, 

                                      19
<PAGE>

the Note Issuer and the Clearing Agency (through the Clearing Agency 
Participants) in writing that the continuation of a book-entry system through 
the Clearing Agency is no longer in the best interests of the Holders of such 
Series, the Administrator shall notify the Clearing Agency, the Indenture 
Trustee and all such Holders of such Series in writing of the occurrence of 
any such event and of the availability of Definitive Notes of such Series to 
the Holders of such Series requesting the same. Upon surrender to the 
Indenture Trustee of the Global Notes of such Series by the Clearing Agency 
accompanied by registration instructions from such Clearing Agency for 
registration, the Indenture Trustee shall authenticate and deliver Definitive 
Notes of such Series.  None of the Note Issuer, the Note Registrar, or the 
Indenture 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 Notes of any 
Series, all references herein to obligations with respect to such Series 
imposed upon or to be performed by the Clearing Agency shall be deemed to be 
imposed upon and performed by the Indenture Trustee, to the extent applicable 
with respect to such Definitive Notes and the Indenture Trustee shall 
recognize the Holders of the Definitive Notes as Holders hereunder.

            SECTION 2.14. CUSIP NUMBER.  The Note Issuer in issuing any Note or
Series of Notes may use a "CUSIP" number and, if so used, the Indenture Trustee
shall use the CUSIP number in any notices to the Holders thereof as a
convenience to such Holders; PROVIDED, that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes and that reliance may be placed only on
the other identification numbers printed on the Notes. The Note Issuer shall
promptly notify the Indenture Trustee in writing of any change in the CUSIP
number with respect to any Note.

            SECTION 2.15. LETTER OF REPRESENTATIONS.  Notwithstanding anything
to the contrary in this Indenture or any Series Supplement or any Trust Issuance
Certificate, the parties hereto shall comply with the terms of each Letter of
Representations.

            SECTION 2.16. RELEASE OF NOTE COLLATERAL.  Subject to Section 
11.01, the Indenture Trustee shall release property from the lien of this 
Indenture only as specified in Section 8.02(d) or upon receipt of an Issuer 
Request accompanied by an Officer's Certificate, an Opinion of Counsel and 
Independent Certificates in accordance with TIA Sections 314(c) and 314(d)(l) 
or an Opinion of Counsel in lieu of such Independent Certificates to the 
effect that the TIA does not require any such Independent Certificates.

            SECTION 2.17. SPECIAL TERMS APPLICABLE TO SUBSEQUENT TRANSFERS OF
CERTAIN NOTES.

            (a)    Certain Series of Notes may not be registered under the
Securities Act, or the securities laws of any other jurisdiction. Consequently,
such Unregistered Notes shall not be transferable other than pursuant to an
exemption from the registration requirements of the Securities Act and
satisfaction of certain other provisions specified herein or in the related
Trust Issuance Certificate or Series Supplement, if any. Unless otherwise
provided in the related Trust 

                                      20
<PAGE>

Issuance Certificate or Series Supplement, if any, no sale, pledge or other 
transfer of any Unregistered Note (or interest therein) may be made by any 
Person unless either (i) such sale, pledge or other transfer is made to a 
"qualified institutional buyer" (as defined under Rule 144A under the 
Securities Act) or to an "institutional accredited investor" (as described in 
Rule 501(a)(l), (2), (3) or (7) under the Securities Act) and, if so 
requested by the Grantee or the Indenture Trustee, such proposed transferee 
executes and delivers a certificate to such effect in form and substance 
satisfactory to the Indenture Trustee and the Note Issuer, or (ii) such sale, 
pledge or other transfer is otherwise made in a transaction exempt from the 
registration requirements of the Securities Act, in which case (A) the 
Indenture Trustee shall require that both the prospective transferor and the 
prospective transferee  to the Indenture Trustee and the Note Issuer in 
writing the facts surrounding such transfer, which certification shall be in 
form and substance satisfactory to the Indenture Trustee and the Note Issuer, 
and (B) the Indenture Trustee shall require a written opinion of counsel 
(which shall not be at the expense of the Note Issuer, the Servicer or the 
Indenture Trustee) satisfactory to the Note Issuer and the Indenture Trustee 
to the effect that such transfer will not violate the Securities Act. Neither 
the Grantee, the Note Issuer, the Indenture Trustee nor the Servicer shall be 
obligated to register any Unregistered Notes under the Securities Act, 
qualify any Unregistered Notes under the securities laws of any state or 
provide registration rights to any purchaser or holder thereof

            (b)    Unless otherwise provided in the related Trust Issuance
Certificate or Series Supplement, the Unregistered Notes may not be acquired by
or for the account of a Benefit Plan and, by accepting and holding an
Unregistered Note, the Holder thereof shall be deemed to have represented and
warranted that it is not a Benefit Plan and, if requested to do so by the Note
Issuer or the Indenture Trustee, the Holder of an Unregistered Note shall
execute and deliver to the Indenture Trustee a certificate to such effect in
form and substance satisfactory to the Indenture Trustee and the Note Issuer.

            (c)    Unless otherwise provided in the related Trust Issuance
Certificate or Series Supplement, Unregistered Notes shall be issued in the form
of Definitive Notes, shall be in fully registered form and Sections 2.11 and
2.12 of this Indenture shall not apply thereto.

            (d)    Each Unregistered Note shall bear legends to the effect set
forth in subsections (a) and (b) (if subsection (b) is applicable) above.

            SECTION 2.18. TAX TREATMENT.  The Note Issuer and the Indenture
Trustee, by entering into this Indenture, and the Holders and any Persons
holding a beneficial interest in any Note, by acquiring any Note or interest
therein, (i) express their intention that the Notes qualify under applicable tax
law as indebtedness of Illinois Power secured by the Note Collateral and
(ii) agree to treat the Notes as indebtedness of Illinois Power secured by the
Note Collateral for the purpose of federal income, state and local income and
franchise taxes, and any other taxes imposed upon, measured by or based upon
gross or net income, unless other required by appropriate taxing authorities.

                                      21

            SECTION 2.19. STATE PLEDGE.  At the Closing Date, under the laws of
the State of Illinois and the United States in effect on the Closing Date, the
State of Illinois has agreed with the Holders, pursuant to Section 18-105(b) of
the Funding Law, as follows:

                   "(b)   The State pledges to and agrees with the
            holders of any transitional funding instruments who may enter
            into contracts with an electric utility, grantee, assignee or
            issuer pursuant to this Article XVIII that the State will not
            in any way limit, alter, impair or reduce the value of
            intangible transition property created by, or instrument
            funding charges approved by, a transitional funding order so
            as to impair the terms of any contract made by such electric
            utility, grantee, assignee or issuer with such holders or in
            any way impair the rights and remedies of such holders until
            the pertinent grantee instruments or, if the related
            transitional funding order does not provide for the issuance
            of grantee instruments, the transitional funding instruments
            and interest, premium and other fees, costs and charges
            related thereto, as the case may be, are fully paid and
            discharged. Electric utilities, grantees and issuers are
            authorized to include these pledges and agreements of the
            State in any contract with the holders of transitional
            funding instruments or with any assignees pursuant to this
            Article XVIII and any assignees are similarly authorized to
            include these pledges and agreements of the State in any
            contract with any issuer, holder or any other assignee.
            Nothing in this Article XVIII shall preclude the State of
            Illinois from requiring adjustments as may otherwise be
            allowed by law to the electric utility's base rates,
            transition charges, delivery services charges, or other
            charges for tariffed services, so long as any such adjustment
            does not directly affect or impair any instrument funding
            charges previously authorized by a transitional funding order
            issued by the [ICC]."

As a result of the foregoing pledge, the State of Illinois may not, except as
provided in the succeeding sentence, in any way limit, alter, impair or reduce
the value of the ITP or the IFCs in a manner substantially impairing this
Indenture or the rights and remedies of the Holders (and, consequently, may not
revoke, reduce, postpone or terminate any Funding Order or the rights of the
Holders to receive IFC Payments and all other proceeds of the 1998 Transition
Property), until the Notes, together with interest thereon, are fully paid and
discharged. Notwithstanding the immediately preceding sentence, the State of
Illinois would be allowed to effect a temporary impairment of the Holders'
rights if it could be shown that such impairment was necessary to advance a
significant and legitimate public purpose.

                                     ARTICLE III
                                      COVENANTS

            SECTION 3.01. PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST. 
The principal of and premium, if any, and interest on the Notes will be duly and
punctually paid in accordance with the terms of the Notes and this Indenture.
Amounts properly withheld under the Code or other tax laws by any Person from a
payment to any Holder of interest or principal or premium, if any, shall be
considered as having been paid by the Note Issuer to such Holder for all
purposes of this Indenture.

            SECTION 3.02. MAINTENANCE OF OFFICE OR AGENCY.  The Note Issuer will
maintain in Chicago, Illinois, an office or agency, Harris Trust and Savings
Bank, as Indenture Trustee, Corporate Trust Office, 311 West Monroe Street, 12th
Floor, Chicago, Illinois 60606, where Notes may be surrendered for registration
of transfer or exchange. The Note Issuer hereby initially appoints the Indenture
Trustee to serve as its agent for the foregoing purposes. The Note Issuer will
give prompt written notice to the Indenture 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 Indenture Trustee with the address thereof, such surrenders may be made at
the Corporate Trust Office of the Indenture Trustee, and the Note Issuer hereby
appoints the Indenture Trustee as its agent to receive all such surrenders.

            SECTION 3.03. MONEY FOR PAYMENTS TO BE HELD IN TRUST.  As provided
in Section 8.02(a), all payments of amounts due and payable with respect to any
Notes that are to be made from amounts withdrawn from the Collection Account
pursuant to Section 8.02(d) shall be made on behalf of the Note Issuer by the
Indenture Trustee or by another Paying Agent, and no amounts so withdrawn from
the Collection Account for payments with respect to any Notes shall be paid over
to the Note Issuer except as provided in this Section and Section 8.02.

            The Note Issuer will cause each Paying Agent other than the
Indenture Trustee to execute and deliver to the Indenture Trustee an instrument
in which such Paying Agent shall agree with the Indenture Trustee (and if the
Indenture 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 Indenture Trustee written notice of any default
     by the Note Issuer of which it has actual knowledge in the making of
     any payment required to be made with respect to the Notes;

                                      23
<PAGE>

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

            (iv)   immediately resign as a Paying Agent and forthwith pay
     to the Indenture Trustee all sums held by it in trust for the payment
     of Notes if at any time it determines that it has ceased to meet the
     standards required to be met by a Paying Agent at the time of such
     determination; and

            (v)    comply with all requirements of the Code and other tax
     laws 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 Indenture or for any other purpose, by Issuer
Order direct any Paying Agent to pay to the Indenture Trustee all sums held in
trust by such Paying Agent, such sums to be held by the Indenture Trustee upon
the same trusts as those upon which the sums were held by such Paying Agent; and
upon such payment by any Paying Agent to the Indenture Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

            Subject to applicable laws with respect to escheat of funds, any
money held by the Indenture 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 an 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
Indenture Trustee or such Paying Agent with respect to such trust money shall
thereupon cease; PROVIDED, HOWEVER, that the Indenture 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 Chicago, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Note Issuer. The Indenture Trustee may also adopt and
employ, at the expense of the Note Issuer, any other reasonable means of
notification of such repayment (including, but not limited to, 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 Indenture
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 business trust under the laws of the
State of Delaware (unless it 

                                      24
<PAGE>

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 Indenture, the Notes, the Note Collateral and each 
other instrument or agreement included in the Note Collateral.

            SECTION 3.05. PROTECTION OF NOTE COLLATERAL.  The Note Issuer will
from time to time execute and deliver all such supplements and amendments hereto
and all filings with the ICC pursuant to the Funding Order or to the Funding Law
and all 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
     the priority thereof) of this Indenture or carry out more effectively
     the purposes hereof,

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

            (iii)  enforce any of the Note Collateral;

            (iv)   preserve and defend title to the Note Collateral and the
     rights of the Indenture Trustee and the Holders in such Note
     Collateral against the Claims of all Persons and parties, including
     the challenge by any party to the validity or enforceability of any
     Funding Order, any Tariff, the Intangible Transition Property or any
     proceeding relating thereto and institute any action or proceeding
     necessary to compel performance by the ICC or the State of Illinois of
     any of its obligations or duties under the Funding Law, the State
     Pledge, or any Funding Order; or

            (v)    pay any and all taxes levied or assessed upon all or any
     part of the Note Collateral.

The Note Issuer hereby designates the Indenture Trustee its agent and
attorney-in-fact to execute any filings with the ICC, financing statements,
continuation statements or other instrument required by the Indenture Trustee
pursuant to this Section, it being understood that the Indenture Trustee shall
have no such obligation or any duty to prepare such documents.

            SECTION 3.06. OPINIONS AS TO NOTE COLLATERAL.  

            (a)     On the Series Issuance Date for each Series (including the
Closing Date), the Note Issuer shall furnish to the Indenture Trustee an Opinion
of Counsel either stating that, in the opinion of such counsel, such action has
been taken with respect to the recording and filing of this Indenture, any
indentures supplemental hereto, and any other requisite documents, and with

                                      25
<PAGE>

respect to the execution and filing of any filings with the ICC pursuant to 
the Funding Law and the applicable Funding Order and any financing statements 
and continuation statements, as are necessary to perfect and make effective 
the lien and security interest of this Indenture to the Note Collateral and 
reciting the details of such action, or stating that, in the opinion of such 
counsel, no such action is necessary to make such lien and security interest 
effective.

            (b)    On or before September 30 in each calendar year, while any
Series is outstanding, beginning on September 30, 1999, the Note Issuer shall

the opinion of such counsel, such action has been taken with respect to the
recording, filing, re-recording and refiling of this Indenture, any indentures

necessary to maintain the lien and security interest created by this Indenture
to the Note Collateral and reciting the details of such action or stating that
in the opinion of such counsel no such action is necessary to maintain such lien
and security interest. Such Opinion of Counsel shall also describe the
recording, filing, re-recording and refiling of this Indenture, any indentures
supplemental hereto and any other requisite documents and the execution and
filing of any filings with the ICC, financing statements and continuation
statements that will, in the opinion of such counsel, be required to maintain
the lien and security interest created by this Indenture to the Note Collateral
until September 30 in the following calendar year.

            (c)    Prior to the effectiveness of any Subsequent Sale Agreement
or any amendment to any Sale Agreement, the Note Issuer shall furnish to the
Indenture Trustee an Opinion of Counsel either (A) stating that, in the opinion
of such counsel, all filings, including filings with the ICC pursuant to the
Funding Law, or the Funding Order, have been executed and filed that are
necessary fully to preserve and protect the interest of the Note Issuer and the
Indenture Trustee in the Intangible Transition Property and the proceeds thereof
and the other Note Collateral, and reciting the details of such filings or
referring to prior Opinions of Counsel in which such details are given, or
(B) stating that, in the opinion of such counsel, no such action shall be
necessary to preserve and protect such interest.

            SECTION 3.07. PERFORMANCE OF OBLIGATIONS; SERVICING SEC 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
Note Collateral and (ii) will not take any action and will use its best 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 provided in
this Indenture, any Trust Issuance Certificate, any Series Supplement, the Sale
Agreement, any Subsequent Sale Agreement related to the applicable 

                                      26
<PAGE>

Note Collateral, the Servicing Agreement, the Administration 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 Indenture, and any performance of such
duties by a Person identified to the Indenture Trustee herein or in an Officer's
Certificate of the Note Issuer shall be deemed to be action taken by the Note
Issuer.

            (c)    The Note Issuer will punctually perform and observe all of
its obligations and agreements contained in this Indenture, the Basic Documents
and in the instruments and agreements included in the Note Collateral,
including, but not limited to, filing or causing to be filed all filings with
the ICC pursuant to the Funding Law or the Funding Order, all UCC financing
statements and continuation statements required to be filed by it by the terms
of this Indenture, the Sale Agreement, any Subsequent Sale Agreement and the
Servicing Agreement in accordance with and within the time periods provided for
herein and therein.

            (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 Indenture Trustee and the Rating Agencies,
and shall specify in such notice the response or action, if any, the Note Issuer
has taken or 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 Intangible
Transition Property or the IFCs, 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 of
termination to the Servicer and the Rating Agencies of the Servicer's rights and
powers pursuant to Section 7.01 of the Servicing Agreement, the Note Issuer
shall appoint a successor Servicer (the "Successor Servicer") with the Grantee'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 Grantee, the Note Issuer and the
Indenture 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 Successor Servicer, the Indenture Trustee may petition the
ICC 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 Servicer as it and such successor shall
agree, subject to the limitations set forth below and in the Servicing
Agreement.

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

                                      27
<PAGE>

            (g)    Without derogating from the absolute nature of the assignment
Granted to the Indenture Trustee under this Indenture or the rights of the
Indenture Trustee hereunder, the Note Issuer agrees that it will not, without
the prior written consent of the Indenture Trustee or the Holders of at least a
majority in Outstanding Amount of the Notes of all Series, amend, modify, waive,
supplement, terminate or surrender, or agree to any amendment, modification,
supplement, termination, waiver or surrender of, the terms of any Note
Collateral or the Basic Documents, or waive timely performance or observance by
Illinois Power, the Grantee or the Servicer under the Grant Agreement, any

     (i) subject to clause (ii), principal in accordance with the Expected
     Amortization Schedule therefor, (ii) if such Series is to be redeemed,
     the Optional Redemption Price therefor on the Optional Redemption Date

            (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

     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 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 of such Series 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 Indenture Trustee
     an Opinion of Counsel to the effect that the Holders of the Notes of

     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;

            (g)    the Note Issuer delivers to the Indenture Trustee an
     Officer's Certificate and an Opinion of Counsel, each stating that all
     conditions precedent to the satisfaction and discharge of the Notes of
     such Series to the extent contemplated by this Article IV have been
     complied with; and

            (h)    the Rating Agency Condition shall have been satisfied
     with respect to the exercise of any Legal Defeasance Option or
     Covenant Defeasance Option.

            Before or after a deposit pursuant to this Section 4.02 with respect
to any Series of Notes, the Note Issuer may make arrangements satisfactory to
the Indenture 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 Indenture Trustee pursuant to Section

applied according to Section 3.03 and thereupon such Paying Agent shall be
released from all further liability with respect to such moneys.

     this Indenture or in any certificate or other writing delivered

     Certificate or Series Supplement, if any.

            The Note Issuer shall deliver to a Responsible Officer of the
Indenture Trustee and the Rating Agencies, within five days after a Responsible
Officer of the Note Issuer has actual knowledge of the occurrence thereof,
written notice in the form of an Officer's Certificate of any event (i) which is
an Event of Default under clause (vii) or (ii) which with the giving of notice
and the lapse of time would become an Event of Default under clause (iv),
including, in each case, the status of such Event of Default 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 (other than an Event of Default under clause (vii) of
Section 5.01) should occur and be continuing with respect to any Series, then
and in every such case the Indenture Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes of
all Series may declare all the Notes to be immediately due and payable, by a
notice in writing to the Note Issuer (and to the Indenture Trustee if given by
Holders), and upon any such declaration the unpaid principal amount of the Notes
of all Series, together with accrued and unpaid interest thereon through the
date of acceleration, shall become immediately due and payable.

            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 Indenture Trustee as hereinafter in this Article V provided, the
Holders of Notes representing a majority of the Outstanding Amount of the Notes
of all Series, by written notice to the Note Issuer and the Indenture Trustee,
may rescind and annul such declaration and its consequences if:

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

                                       40
<PAGE>

                   (A)    all payments of principal of and premium, if any,
     and interest on all Notes of all Series 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 Indenture
     Trustee hereunder and the reasonable compensation, expenses,
     disbursements and advances of the Indenture Trustee and its agents and
     counsel; and

            (ii)   all Events of Default with respect to all Series, other
     than the nonpayment of the principal of the Notes of all Series 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 INDENTURE TRUSTEE.

            (a)     If an Event of Default under Section 5.01(i), (ii) or (iii)
has occurred and is continuing with respect to any Series, subject to Section
11.18, the Indenture 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,
subject to the limitations on recourse set forth herein, may enforce the same
and collect in the manner provided by law out of the Note Collateral and the
proceeds thereof, the whole amount then due and payable on the Notes of such
Series for principal, premium, if any, and interest, with interest upon the
overdue principal and premium, if any, 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 such Series or the applicable Class
of such Series and in addition thereto such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Indenture
Trustee and its agents and counsel.

            (b)    If an Event of Default (other than Event of Default under
clause (vii) of Section 5.01) occurs and is continuing with respect to any
Series, the Indenture 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 Holders of such Series, by such appropriate Proceedings as the
Indenture Trustee shall deem most effective to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to
enforce any other proper remedy or legal or equitable right vested in the
Indenture Trustee by this Indenture or by law.

                                       41
<PAGE>

            (c)    If an Event of Default under Section 5.01(v) or (vi) has
occurred and is continuing, the Indenture Trustee, irrespective of whether the
principal of any Notes of any Series shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the
Indenture Trustee shall have made any demand pursuant to the provisions of this
Section, shall be entitled and empowered, by intervention in any Proceedings
related to such Event of Default or otherwise:

            (i)    to file and prove a claim or claims for the whole amount
     of principal, premium, if any, 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 the Indenture
     Trustee (including any claim for reasonable compensation to the
     Indenture Trustee and each predecessor Indenture Trustee, and their
     respective agents, attorneys and counsel, and for reimbursement of all
     expenses and liabilities incurred, and all advances made, by the
     Indenture Trustee and each predecessor Indenture Trustee, except as a
     result of negligence or bad faith) and of the Holders 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 in
     bankruptcy, 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 Holders and of the
     Indenture 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 Holders to make
payments to the Indenture Trustee, and, in the event that the Indenture Trustee
shall consent to the making of payments directly to such Holders, to pay to the
Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Indenture Trustee and each
predecessor Indenture Trustee except as a result of negligence or bad faith.

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

            (e)    All rights of action and of asserting claims under this
Indenture, or under any of the Notes of any Series, may be enforced by the
Indenture Trustee without the possession 

                                       42
<PAGE>

of any of the Notes of such Series or the production thereof in any trial or 
other Proceedings relative thereto, and any such action or proceedings 
instituted by the Indenture 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 Indenture 
Trustee, each predecessor Indenture Trustee and their respective agents and 
attorneys, shall be for the ratable benefit of the Holders of the Notes of 
such Series.

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

            SECTION 5.04. REMEDIES; PRIORITIES.

            (a)    If an Event of Default (other than an Event of Default under
clause (vii) of Section 5.01) shall have occurred and be continuing with respect
to a Series, the Indenture 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 of such Series or under this Indenture with respect thereto,
     whether by declaration of acceleration or otherwise, and, subject to
     the limitations on recovery set forth herein, enforce any judgment
     obtained, and collect moneys adjudged due upon such Notes;

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

            (iii)  exercise any remedies of a secured party under the UCC
     or the Funding Law and take any other appropriate action to protect
     and enforce the rights and remedies of the Indenture Trustee and the
     Holders of the Notes of such Series; and

            (iv)   sell the Note 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 Indenture Trustee may not sell or otherwise
liquidate any portion of the Note Collateral following such an Event of Default,
other than an Event of Default described in Section 5.01(i), (ii) or (iii), with
respect to any Series unless (A) the Holders of 100 percent of the Outstanding
Amount of the Notes of all Series consent thereto, (B) the proceeds of such sale
or liquidation distributable to the Holders of all Series are sufficient to
discharge in full all amounts then due and unpaid upon such Notes for principal,
premium, if any, and interest after taking into account payment of all amounts
due prior thereto pursuant to the priorities set forth 

                                       43
<PAGE>

in Section 8.02(d) or (C) the Indenture Trustee determines that the Note 
Collateral will not continue to provide sufficient funds for all payments on 
the Notes of all Series as they would have become due if the Notes had not 
been declared due and payable, and the Indenture Trustee obtains the consent 
of Holders of 66-2/3 percent of the Outstanding Amount of the Notes of all 
Series. In determining such sufficiency or insufficiency with respect to 
clause (B) and (C), the Indenture 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 Note Collateral for such purpose

            (b)    If an Event of Default under clause (vii) of Section 5.01
shall have occurred and be continuing, the Indenture Trustee, for the benefit of
the Holders, shall be entitled and empowered to the extent permitted by
applicable law, to institute or participate in Proceedings reasonably necessary
to compel performance of or to enforce the State Pledge and to collect any
monetary damages incurred by the Holders or the Indenture Trustee as a result of
any such Event of Default, and may prosecute any such Proceeding to final
judgment or decree.

            (c)    If the Indenture 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 PRESERVATION OF THE NOTE COLLATERAL.  If the
Notes of all Series 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 Indenture Trustee may, but need not, elect to
maintain possession of the Note Collateral. It is the desire of the parties
hereto and the Holders that there be at all times sufficient funds for the
payment of principal of and premium, if any, and interest on the Notes, and the
Indenture Trustee shall take such desire into account when determining whether
or not to maintain possession of the Note Collateral. In determining whether to
maintain possession of the Note Collateral, the Indenture 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 Note Collateral for such
purpose.

            SECTION 5.06. LIMITATION OF SUITS.  No Holder of any Note of any
Series shall have any right to institute any Proceeding, judicial or otherwise,
with respect to this 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
     Indenture Trustee of a continuing Event of Default with respect to
     such Series;

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

                                       44
<PAGE>

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

            (iv)   the Indenture 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 Indenture Trustee during such 60-day period by the
     Holders of a majority of the Outstanding Amount of the Notes of all
     Series;

it being understood and intended that no one or more Holders of Notes shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Notes or to obtain or to seek to obtain priority or preference over
any other Holders or to enforce any right under this Indenture, except in the
manner herein provided.

            In the event the Indenture 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 of
all Series, the Indenture Trustee in its sole discretion may determine what
action, if any, shall be taken, notwithstanding any other provisions of this
Indenture.

            SECTION 5.07. UNCONDITIONAL RIGHTS OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM, IF ANY, AND INTEREST.  Notwithstanding any other provisions in this
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 the due dates thereof expressed in such Note or in this Indenture, (ii) the
unpaid principal, if any, of such Notes on the Final Maturity Date therefor or
(iii) in the case of redemption, receive payment of the unpaid principal and
premium, if any, and interest, if any, on such Note on the Optional Redemption
Date 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 Indenture
Trustee or any Holder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or
abandoned for any reason or has been determined adversely to the Indenture
Trustee or to such Holder, then and in every such case the Note Issuer, the
Indenture Trustee and the Holders 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 Indenture Trustee and
the Holders shall continue as though no such Proceeding had been instituted.

                                       45
<PAGE>

            SECTION 5.09. RIGHTS AND REMEDIES CUMULATIVE. No right or remedy
herein conferred upon or reserved to the Indenture Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

            SECTION 5.10. DELAY OR OMISSION NOT A WAIVER.  No delay or 
omission of the Indenture Trustee or any Holder 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 Indenture Trustee or to the Holders may be 
exercised from time to time, and as often as may be deemed expedient, by the 
Indenture Trustee or by the Holders, as the case may be.

            SECTION 5.11. CONTROL BY HOLDERS. The Holders of a majority of the
Outstanding Amount of the Notes of all Series (or, if less than all Series or
Classes are affected, the affected Series or Class or Classes) shall have the
right to direct the time, method and place of conducting any Proceeding for any
remedy available to the Indenture Trustee with respect to the Notes of such
Series or Class or Classes or exercising any trust or power conferred on the
Indenture Trustee with respect to such Series or Class or Classes; PROVIDED that

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

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

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

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

PROVIDED, HOWEVER, that, the Indenture Trustee's duties shall be subject to
Section 6.01, and the Indenture Trustee need not take any action that it
determines might involve it in liability or might materially adversely affect
the rights of any Holders 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 of all Series as provided in
Section 5.02, the Holders of Notes representing not less than a majority of the
Outstanding Amount of the Notes of all Series may waive any past Default or
Event of Default and its consequences except a Default (a) in payment of
principal of or premium, if any, 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 of all Series or Classes
affected. In the case of any such waiver, the Note Issuer, the Indenture 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 have been cured and not to have occurred,
for every purpose of this 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 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 Indenture, or in any suit
against the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to (a) any suit instituted by the
Indenture Trustee, (b) any suit instituted by any Holder, or group of Holders,
in each case holding in the aggregate more than 10 percent of the Outstanding
Amount of the Notes of a Series or (c) any suit instituted by any Holder 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 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 premium, if any, and interest on any
Note on or after the Optional Redemption Date 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 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 Indenture 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 Indenture Trustee's right to
seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the lien of this Indenture nor any
rights or remedies of the Indenture Trustee or the Holders shall be impaired by
the recovery of any judgment by the Indenture Trustee against the Note Issuer or
by the levy of any execution under such judgment upon any portion of the Note
Collateral or any other assets of the Note Issuer.

            SECTION 5.16. PERFORMANCE AND ENFORCEMENT OF CERTAIN OBLIGATIONS.

            (a)    Promptly following a request from the Indenture Trustee to do
so and at the Note Issuer's expense, the Note Issuer agrees to take all such
lawful action as the Indenture Trustee may request to compel or secure the
performance and observance by Illinois Power, the Grantee and the Servicer, as
applicable, of each of their obligations to the Note Issuer under or in
connection with the Grant Agreement or any Subsequent Grant Agreement, the Sale
Agreement, or any Subsequent Sale Agreement and the Servicing Agreement,
respectively, in accordance with the terms thereof, and to exercise any and all
rights, remedies, powers and privileges lawfully available to the Note Issuer
under or in connection with any such agreements, respectively, to the extent and
in the manner directed by the Indenture Trustee, including the transmission of
notices of default on the part of Illinois Power, the Grantee or the Servicer
thereunder and the institution of legal or administrative actions or proceedings
to compel or secure performance by Illinois Power, the Grantee or the Servicer
of each of their respective obligations under the Grant Agreement, any
Subsequent Grant Agreement, the Sale Agreement, any Subsequent Sale Agreement
and the Servicing Agreement, respectively.

            (b)    If an Event of Default has occurred and is continuing, the
Indenture 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 of all Series
shall, subject to Article VI, exercise all rights, remedies, powers, privileges
and claims of the Note Issuer against the Grantee or the Servicer under or in
connection with the Sale Agreement, any Subsequent 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 Grantee 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, any Subsequent Sale Agreement or the Servicing Agreement,
respectively, and any right of the Note Issuer to take such action shall be
suspended.

                                THE INDENTURE TRUSTEE

            SECTION 6.01. DUTIES OF INDENTURE TRUSTEE.

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

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

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

            (ii)   in the absence of bad faith on its part, the Indenture
     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 Indenture Trustee and conforming to the
     requirements of this Indenture; however, the Indenture Trustee shall
     examine the certificates and opinions to determine whether or not they
     conform to the requirements of this Indenture.

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

            (i)    this paragraph (c) does not limit the effect of
     paragraph (b) of this Section 6.01;

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

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

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

                                       49
<PAGE>

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

            (g)    No provision of this Indenture shall require the Indenture
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 Indenture relating to the conduct or
affecting the liability of or affording protection to the Indenture Trustee
shall be subject to the provisions of this Section and to the provisions of the
TIA.

            (i)    In the event that the Indenture Trustee is also acting as
Paying Agent or Note Registrar hereunder, the rights and protections of this
Article VI shall also be afforded to the Indenture Trustee in its capacity as
Paying Agent or Note Registrar.

            (j)    Except as expressly set forth in the Basic Documents, the
Indenture Trustee shall have no obligation to administer, service or collect
Intangible Transition Property or to maintain, monitor or otherwise supervise
the administration, servicing or collection of the Intangible Transition
Property.

            SECTION 6.02. RIGHTS OF INDENTURE TRUSTEE.

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

            (b)    Before the Indenture Trustee acts or refrains from acting, it
may require and shall be entitled to receive an Officer's Certificate or an
Opinion of Counsel that such action is required or permitted hereunder. The
Indenture Trustee shall not be liable for any action it takes or omits to take
in good faith in reliance on such Officer's Certificate or Opinion of Counsel.

            (c)    The Indenture 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 Indenture Trustee shall
not be responsible for any misconduct or negligence on the part of, or for the
supervision of, any such agent, attorney, custodian or nominee appointed with
due care by it hereunder.

            (d)    The Indenture 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, 

                                       50
<PAGE>

HOWEVER, that the Indenture Trustee's conduct does not constitute willful 
misconduct, negligence or bad faith.

            (e)    The Indenture Trustee may consult with counsel, and the
advice or opinion of counsel with respect to legal matters relating to this
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.

            SECTION 6.03. INDIVIDUAL RIGHTS OF INDENTURE TRUSTEE.  The Indenture
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 Indenture Trustee. Any Paying Agent,
Note Registrar, co-registrar or co-paying agent may do the same with like
rights. However, the Indenture Trustee must comply with Sections 6.11 and 6.12.

            SECTION 6.04. INDENTURE TRUSTEE'S DISCLAIMER.  The Indenture Trustee
shall not be responsible for and makes no representation as to the validity or
adequacy of this 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 Indenture or in any
document issued in connection with the sale of the Notes or in the Notes other
than the Indenture Trustee's certificate of authentication.

            SECTION 6.05. NOTICE OF DEFAULTS.  If a Default occurs and is
continuing with respect to any Series and if it is actually known to a
Responsible Officer of the Indenture Trustee, the Indenture Trustee shall mail
to each Holder of Notes of all Series notice of the Default within 90 days after
it occurs. Except in the case of a Default in payment of principal of and
premium, if any, or interest on any Note, the Indenture Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of Holders.  Except
as provided in the first sentence of this Section 6.05, in no event shall the
Indenture Trustee be deemed to have knowledge of a Default.

            SECTION 6.06. REPORTS BY INDENTURE TRUSTEE TO HOLDERS.

            (a)    So long as Notes are Outstanding and the Indenture Trustee is
the Note Registrar and Paying Agent, within the prescribed period of time for
tax reporting purposes after the end of each calendar year it shall deliver to
each relevant current or former Holder such information in its possession as may
be required to enable such Holder to prepare its Federal and state income tax
returns.

            (b)    With respect to each Series of Notes, on or prior to each
Payment Date or Special Payment Date therefor, the Indenture Trustee will
deliver to each Holder of such Notes on such Payment Date or Special Payment
Date a statement as provided and prepared by the 

                                       51
<PAGE>

Servicer which will include (to the extent applicable) the following 
information (and any other information so specified in the applicable Trust 
Issuance Certificate or Series Supplement, if any,) as to the Notes of such 
Series with respect to such Payment Date or Special Payment Date or the 
period since the previous Payment Date, as applicable:

            (i)    the amount of the payment to Holders allocable to
     principal, if any;

            (ii)   the amount of the payment to Holders allocable to
     interest;

            (iii)  the aggregate Outstanding Amount of such Notes, after
     giving effect to any payments allocated to principal reported under
     (i) above; and

            (iv)   the difference, if any, between the amount specified in
     subsection (iii) above and the Outstanding Amount specified in the
     related Expected Amortization Schedule.

            (c)    The Note Issuer shall send a copy of each of the Certificate
of Compliance delivered to it pursuant to Section 3.03 of the Servicing
Agreement and the Annual Accountant's Report delivered to it pursuant to Section
3.04 of the Servicing Agreement to the Rating Agencies. A copy of such
certificate and report may be obtained by any Holder by a request in writing to
the Indenture Trustee.

            SECTION 6.07. COMPENSATION AND INDEMNITY.  The Note Issuer shall pay
to the Indenture Trustee from time to time reasonable compensation for its
services. The Indenture 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 Indenture Trustee for all reasonable out-of-pocket expenses
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 Indenture Trustee's
agents, counsel, accountants and experts. The Note Issuer shall indemnify the
Indenture Trustee and its officers, directors, employees and agents against any
and all loss, liability or expense (including attorneys' fees and expenses)
incurred by it in connection with the administration of this trust and the
performance of its duties hereunder. The Indenture Trustee shall notify the Note
Issuer as soon as is reasonably practicable of any claim for which it may seek
indemnity. Failure by the Indenture 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 Indenture Trustee may have separate counsel and the
Note Issuer shall pay the fees and expenses of such counsel. The Note Issuer
need not reimburse any expense or indemnify against any loss, liability or
expense incurred by the Indenture Trustee through the Indenture Trustee's own
wilful misconduct, negligence or bad faith.

            The payment obligations to the Indenture Trustee pursuant to this
Section shall survive the discharge of this Indenture or the earlier resignation
or removal of the Indenture Trustee. When the Indenture Trustee incurs expenses
after the occurrence of a Default specified 

                                       52
<PAGE>

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.

            SECTION 6.08. REPLACEMENT OF INDENTURE TRUSTEE.  The Indenture
Trustee may resign at any time by so notifying the Note Issuer, provided that no
such resignation shall be effective until either (a) the Note Collateral has
been completely liquidated and the proceeds of the liquidation distributed to
the Holders 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 of all Series may remove the
Indenture Trustee by so notifying the Indenture Trustee and may appoint a
successor Indenture Trustee. The Note Issuer shall remove the Indenture Trustee
if:

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

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

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

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

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

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

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

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

                                       53
<PAGE>

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

            SECTION 6.09. SUCCESSOR INDENTURE TRUSTEE BY MERGER.  If the
Indenture 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 Indenture Trustee;
PROVIDED, however, that if such successor Indenture Trustee is not eligible
under Section 6.11, then the successor Indenture Trustee shall be replaced in
accordance with Section 6.08.

            In case at the time such successor or successors by merger,
conversion or consolidation to the Indenture Trustee shall succeed to the trusts
created by this Indenture any of the Notes shall have been authenticated but not
delivered, any such successor to the Indenture 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 Indenture Trustee may authenticate such
Notes either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Notes or in this Indenture
provided that the certificate of the Indenture Trustee shall have.

            SECTION 6.10. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.

            (a)    Notwithstanding any other provisions of this Indenture, at
any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the trust created by this Indenture or the Note Collateral
may at the time be located, the Indenture 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 trust created by this Indenture or the Note Collateral, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Holders, such title to the Note Collateral, or any part hereof, and, subject to
the other provisions of this Section, such powers, duties, obligations, rights
and trusts as the Indenture Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 6.11 and no notice to Holders
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 Indenture Trustee shall be conferred or imposed upon
     and exercised or performed by the Indenture Trustee and such separate
     trustee or co-trustee jointly (it being understood that such separate
     trustee or co-trustee is not authorized to act 

                                       54
<PAGE>

     separately without the Indenture 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 Indenture 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 Note 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 Indenture 
     Trustee;

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

            (iii)  the Indenture 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 Indenture
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 Indenture and
the conditions of this Article VI. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or
property specified in its instrument of appointment, either jointly with the
Indenture Trustee or separately, as may be provided therein, subject to all the
provisions of this Indenture, specifically including every provision of this
Indenture relating to the conduct of, affecting the liability of, or affording
protection to, the Indenture Trustee. Every such instrument shall be filed with
the Indenture Trustee.

            (d)    Any separate trustee or co-trustee may at any time constitute
the Indenture Trustee, its agent or attorney-in-fact with full power and
authority, to the extent not prohibited by law, to do any lawful act under or in
respect of this Indenture on its behalf and in its name. If any separate trustee
or co-trustee shall die, become incapable of acting, resign or be removed, all
of its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

            SECTION 6.11. ELIGIBILITY; DISQUALIFICATION.  The Indenture Trustee
shall at all times satisfy the requirements of TIA Section 310(a) and Section
26(a)(i) of the Investment Company Act of 1940. The Indenture Trustee shall have
a combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition and it shall have a long term debt
rating of A (or the equivalent thereof) or better by all of the Rating Agencies
from which a rating is available. The Indenture Trustee shall comply with TIA
Section 310(b), including the optional provision permitted by the second
sentence of TIA Section 310(b)(9); PROVIDED, HOWEVER, that there shall be
excluded from the operation of TIA Section 310(b)(1) any indenture or indentures
under which other securities of the Note Issuer are outstanding if the
requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

                                       55
<PAGE>

            SECTION 6.12. PREFERENTIAL COLLECTION OF CLAIMS AGAINST NOTE

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

            SECTION 8.01. COLLECTION OF MONEY.  Except as otherwise expressly 
provided herein, the Indenture Trustee may demand payment or delivery of,  
and shall receive and collect, directly and without intervention or 
assistance of any fiscal agent or other intermediary, all money and other 
property payable to or receivable by the Indenture Trustee pursuant to this 
Indenture. The Indenture Trustee shall apply all such money received by it as 
provided in this Indenture. Except as otherwise expressly provided in this 
Indenture, if any default occurs in the making of any payment or performance 
under any agreement or instrument that is part of the Note Collateral, the 
Indenture Trustee may take such action as may be appropriate to enforce such 
payment or performance, subject to Article VI, including the institution and 
prosecution of appropriate Proceedings. Any such action shall be without 
prejudice to any right to claim a Default or Event of Default under this 
Indenture and any right to proceed thereafter as provided in Article V.

            SECTION 8.02. COLLECTION ACCOUNT.

            (a)    Prior to the Series Issuance Date for the first Series of 
Notes issued hereunder, the Note Issuer shall open, at the Indenture 
Trustee's Corporate Trust Office, or at another Eligible Institution, one or 
more segregated trust accounts in the Indenture Trustee's name for the 
deposit of Actual IFC Collections (collectively, the "Collection Account"). 
The Collection Account will consist of four subaccounts: a general subaccount 
(the "General Subaccount"), a reserve subaccount (the "Reserve Subaccount"), 
a subaccount for the Overcollateralization Amount (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, up to the Required Capital Level for any Series of Notes) 
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(d) and (e). The Collection Account shall at all times be maintained in 
an Eligible Deposit Account and only the Indenture 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 Indenture. 
Funds in the Collection Account shall not be commingled with any other 
moneys. All moneys deposited from time to time in the Collection Account, all 
deposits therein pursuant to this 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 Indenture Trustee in the 
Collection Account as part of the Note Collateral as herein provided.


                                      58

<PAGE>

            (b)    The Indenture 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 Indenture Trustee 
shall also pay from the Collection Account any amounts requested to be paid 
by or to the Servicer pursuant to Section 6.06 of the Servicing Agreement.

            (c)    IFC Collections shall be deposited in the General 
Subaccount as provided in Section 6.11 of the Servicing Agreement. All 
deposits to and withdrawals from the Collection Account, all allocations to 
the subaccounts of the Collection Account shall be made by the Indenture 
Trustee in accordance with the written instructions provided by the Servicer 
in the Quarterly Servicer's Certificate.

            (d)    On each Payment Date for any Series of Notes, the 
Indenture Trustee shall apply all amounts on deposit in the Collection 
Account, including all net earnings thereon, to pay the following amounts, in 
accordance with the Quarterly Servicer's Certificate, in the following 
priority:

            (i)    all amounts owed by the Note Issuer to the Indenture
     Trustee (including legal fees and expenses) shall be paid to the
     Indenture Trustee (subject to Section 6.07) and all amounts owed to
     the Delaware Trustee in connection with its acting as Trustee under
     the Trust Agreement shall be paid to the Delaware Trustee, as
     appropriate;

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

            (iii)  the Administration Fee and all unpaid Administration
     Fees, if any, 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 accrued and unpaid Operating Expenses shall be paid to the
     Persons entitled thereto or, if such have been previously paid by the
     Note Issuer, to the Note Issuer in reimbursement thereof; PROVIDED
     that the amount paid on each Payment Date pursuant to this clause (iv)
     shall not exceed $100,000;

            (v)    any overdue Quarterly Interest (together with, to the
     extent lawful, interest on such overdue Quarterly Interest at the
     applicable Note Interest Rate) and then Quarterly Interest for such
     Payment Date with respect to each Series of Notes shall be paid to the
     Holders of such Series of Notes;

            (vi)   principal due and payable on the Notes of any Series as
     a result of an Event of Default or on the Final Maturity Date of the
     Notes of such Series, shall be paid to the Holders of such Series of
     Notes;


                                      59

<PAGE>

            (vii)  Quarterly Principal for such Payment Date with respect
     to each Series of Notes shall be paid to the Holders of such Series of
     Notes;

            (viii) unpaid Operating Expenses shall be paid to the Persons
     entitled thereto or, if such have been previously paid by the Note
     Issuer, to the Note Issuer or as it directs in reimbursement thereof;

            (ix)   the amount, if any, by which the Required Capital Level
     with respect to all Outstanding Series of Notes exceeds the amount in
     the Capital Subaccount as of such Payment Date shall be allocated to
     the Capital Subaccount;

            (x)    the amount, if any, by which the Required
     Overcollateralization Level with respect to all Outstanding Series of
     Notes exceeds the amount in the Overcollateralization Subaccount as of
     such Payment Date shall be allocated to the Overcollateralization
     Subaccount;

            (xi)   funds up to the amount of net earnings on amounts in the
     Collection Account for the prior quarter without cumulation shall be
     paid to the Note Issuer, free from the lien of this Indenture;

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

            (xiii) after principal of and premium, if any, and interest on
     all Notes of all Series, and all of the other foregoing amounts, have
     been paid in full, the balance (including all amounts then held in the
     Overcollateralization Subaccount, the Capital Subaccount and the
     Reserve Subaccount), if any, shall be paid to the Note Issuer, free
     from the lien of this Indenture.

All payments to the Holders of a Series pursuant to clauses (v), (vi) and 
(vii) above or, in the case of clause (vi), if there is more than one Series 
of Notes outstanding all payments to the Holders of all Series, shall be made 
to such Holders pro rata based on the respective principal amounts of Notes 
of such Series held by such Holders, unless, in the case of a Series 
comprised of two or more Classes, the Trust Issuance Certificate or Series 
Supplement, if any, for such Series provides otherwise. Payments in respect 
of principal of and premium, if any, and interest on any Class of Notes will 
be made on a pro rata basis among all the Holders of such Class,

            (e)    If on any Payment Date funds on deposit in the General 
Subaccount are insufficient to make the payments contemplated by clauses (i) 
through (vii) of Section 8.02(d) above, the Indenture 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 (vii) 


                                      60

<PAGE>

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 (ix) and (x) above, the Indenture Trustee shall draw from amounts 
on deposit in the Reserve Subaccount to make such allocations notwithstanding 
the fact that on such Payment Date the allocation contemplated by clause 
(viii) above may not have been fully satisfied.

            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 
Indenture Trustee upon Issuer Order; PROVIDED, HOWEVER, that (i) such 
Eligible Investments shall not mature later than the Business Day prior to 
the next Payment Date for the related Series of Notes and (ii) such Eligible 
Investments shall not be sold, liquidated or otherwise disposed of at a loss 
prior to the maturity thereof. All income or other gain from investments of 
moneys deposited in the Collection Account shall be deposited by the 
Indenture Trustee in the Collection Account, and any loss resulting from such 
investments shall be charged to the Collection Account. The Note Issuer will 
not direct the Indenture 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 
Indenture Trustee to make any such investment or sale, if requested by the 
Indenture Trustee, the Note Issuer shall deliver to the Indenture Trustee an 
Opinion of Counsel, acceptable to the Indenture Trustee, to such effect. In 
no event shall the Indenture Trustee be liable for the selection of Eligible 
Investments or for investment losses incurred thereon. The Indenture 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 or the Servicer to provide timely written 
investment direction. The Indenture 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.

            (b)    Subject to Section 6.01(c), the Indenture 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 Indenture Trustee's 
failure to make payments on such Eligible Investments issued by the Indenture 
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 Indenture Trustee by 11:00 a.m. Eastern Time (or such other time as may 
be agreed by the Note Issuer and Indenture Trustee) on any Business Day; or 
(ii) a Default or Event of Default shall have occurred and be continuing with 
respect to the Notes of any Series but the Notes of such Series shall not 
have been declared due and payable pursuant to Section 5.02, then the 
Indenture Trustee shall, to the fullest extent practicable, invest and 
reinvest funds in the Collection Account in one or more investments which 


                                      61

<PAGE>

qualify as investments in money market funds described under paragraph (d) of 
the definition of Eligible Investments.

            (d)    The parties hereto acknowledge that the Servicer may, 
pursuant to the Servicing Agreement, direct the investment (including 
investment in Eligible Investments) of moneys in the Collection Account on 
behalf of the Note Issuer.

            SECTION 8.04. RELEASE OF NOTE COLLATERAL.

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

            (b)    The Indenture Trustee shall, at such time as there are no 
Notes Outstanding, release any remaining portion of the Note Collateral that 
secured the Notes from the lien of this Indenture and release to the Note 
Issuer or any other Person entitled thereto any funds then on deposit in the 
Collection Account. The Indenture Trustee shall release property from the 
lien of this 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 TIA) Independent Certificates in accordance 
with TIA Sections 314(c) and 3 14(d)(1) meeting the applicable requirements 
of Section 11.01.

            SECTION 8.05. OPINION OF COUNSEL.  The Indenture 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 Indenture Trustee shall also require, as a 
condition to such action, an Opinion of Counsel, in form and substance 
satisfactory to the Indenture 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 Holders in contravention of the provisions 
of this Indenture; PROVIDED, HOWEVER, that such Opinion of Counsel shall not 
be required to express an opinion as to the fair value of the Note 
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 Indenture Trustee in connection with any such 
action.

            SECTION 8.06. REPORTS BY INDEPENDENT ACCOUNTANTS.  As of the 
Closing 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 Indenture and the related Trust Issuance Certificates or 
Series 


                                      62

<PAGE>

Supplements, if any. In the event such firm requires the Indenture Trustee to 
agree to the procedures performed by such firm, the Note Issuer shall direct 
the Indenture Trustee in writing to so agree; it being understood and agreed 
that the Indenture Trustee will deliver such letter of agreement in 
conclusive reliance upon the direction of the Note Issuer, and the Indenture 
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 Indenture Trustee and 
shall promptly appoint a 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 Indenture 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 Indenture Trustee shall promptly 
appoint a successor firm of Independent certified public accountants of 
recognized national reputation; PROVIDED that the Indenture Trustee shall 
have no liability with respect to such appointment if the Indenture 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.

of each Series or Class affected thereby:

            (i)    change the date of payment of any installment of
     principal of or premium, if any, or interest on any Note, or reduce
     the principal amount thereof; the interest rate thereon or premium, if
     any, with respect thereto, change any Optional Redemption Price,
     change the provisions of this Indenture and the related applicable
     Trust Issuance Certificate or Series Supplement, if any, relating to
     the application of collections on, or the proceeds of the sale of; the
     Note Collateral to payment of principal of or premium, if any, or
     interest on the Notes, or change any place of payment where, or the
     coin or currency in which, any Note or the interest thereon is
     payable, or impair the right to institute suit for the enforcement of
     the provisions of this Indenture requiring the application of funds
     available therefor, as provided in Article V, to the payment of any
     such amount due on the Notes on or after the respective due dates
     thereof (or, in the case of optional redemption, on or after the
     Optional Redemption Date);

            (ii)   reduce the percentage of the Outstanding Amount of the
     Notes or of a Series or Class thereof; the consent of the Holders of
     which is required for any such supplemental indenture, or the consent
     of the Holders of which is required for any waiver of compliance with
     certain provisions of this Indenture or certain defaults hereunder and
     their consequences provided for in this Indenture;

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

            (iv)   reduce the percentage of the Outstanding Amount of the

     amendments to any provisions of this Indenture;


                                      65

<PAGE>

            (vi)   modify any of the provisions of this Indenture in such
     manner as to affect the calculation of the amount of any payment of
     interest, principal or premium, if any, due on any Note on any Payment
     Date (including the calculation of any of the individual components of
     such calculation);

            (vii)  permit the creation of any lien ranking prior to or on a
     parity with the lien of this Indenture with respect to any part of the
     Note Collateral or, except as otherwise permitted or contemplated
     herein, terminate the lien of this Indenture on any property at any
     time subject hereto or deprive the Holder of any Note of the security
     provided by the lien of this Indenture; or

            (viii) cause any material adverse federal income tax
     consequences to Illinois Power, the Grantee, the Note Issuer, the
     Delaware Trustee, the Indenture Trustee or the then existing Holders.

            The Indenture Trustee may in its discretion determine whether or 
not any Notes of a Series or Class would be affected by any supplemental 
indenture and any such determination shall be conclusive upon the Holders of 
all Notes of such Series or Class, whether theretofore or thereafter 
authenticated and delivered hereunder. The Indenture Trustee shall not be 
liable for any such determination made in good faith.

            It shall not be necessary for any Act of Holders under this 
Section to approve the particular form of any proposed supplemental 
indenture, but it shall be sufficient if such Act shall approve the substance 
thereof

            Promptly after the execution by the Note Issuer and the Indenture 
Trustee of any supplemental indenture pursuant to this Section, the Note 
Issuer shall mail to the Rating Agencies and the Holders of the Notes to 
which such supplemental indenture relates a notice setting forth in general 
terms the substance of such supplemental indenture. Any failure of the 
Indenture Trustee to mail such notice, or any defect therein, shall not, 
however, in any way impair or affect the validity of any such supplemental 
indenture.

            SECTION 9.03. EXECUTION OF SUPPLEMENTAL INDENTURES.  In 
executing, or permitting the additional trusts created by, any supplemental 
indenture permitted by this Article IX or the modifications thereby of the 
trusts created by this Indenture, the Indenture Trustee shall be entitled to 
receive, and subject to Sections 6.01 and 6.02, shall be fully protected in 
relying upon, an Opinion of Counsel stating that the execution of such 
supplemental indenture is authorized or permitted by this Indenture. The 
Indenture Trustee may, but shall not be obligated to, enter into any such 
supplemental indenture that affects the Indenture Trustee's own rights, 
duties, liabilities or immunities under this Indenture or otherwise.

            SECTION 9.04. EFFECT OF SUPPLEMENTAL INDENTURE.  Upon the 
execution of any supplemental indenture pursuant to the provisions hereof; 
this Indenture shall be and be deemed 


                                      66

<PAGE>

to be modified and amended in accordance therewith with respect to each 
Series or Class of Notes affected thereby, and the respective rights, 
limitations of rights, obligations, duties, liabilities and immunities under 
this Indenture of the Indenture 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 indenture shall be and be 
deemed to be part of the terms and conditions of this Indenture for any and 
all purposes.

            SECTION 9.05. CONFORMITY WITH TRUST INDENTURE ACT.  Every 
amendment of this Indenture and every supplemental indenture executed 
pursuant to this Article IX shall conform to the requirements of the Trust 
Indenture Act as then in effect so long as this Indenture shall then be 
qualified under the Trust Indenture Act.

            SECTION 9.06. REFERENCE IN NOTES TO SUPPLEMENTAL INDENTURES.  
Notes authenticated and delivered after the execution of any supplemental 
indenture pursuant to this Article IX may, and if required by the Indenture 
Trustee shall, bear a notation in form approved by the Indenture Trustee as 
to any matter provided for in such supplemental indenture. If the Note Issuer 
or the Indenture Trustee shall so determine, new Notes so modified as to 
conform, in the opinion of the Indenture Trustee and the Note Issuer, to any 
such supplemental indenture may be prepared and executed by the Note Issuer 
and authenticated and delivered by the Indenture Trustee in exchange for 
Outstanding Notes.

                              REDEMPTION OF NOTES

            SECTION 10.01. OPTIONAL REDEMPTION BY NOTE ISSUER.  The Note 
Issuer may, at its option, redeem all, but not less than all, of the Notes of 
a Series (a) on any Payment Date if, after giving effect to payments that 
would otherwise be made on such Payment Date, the Outstanding Amount of any 
such Series of Notes has been reduced to less than five percent of the 
initial principal balance thereof; or (b) if and to the extent specified in 
the related Trust Issuance Certificate or Series Supplement, if any, on any 
Payment Date on or prior to December 31, 2004, from the proceeds of the 
issuance and sale of the Notes of any other Series. In addition, a Series of 
Notes shall be subject to redemption if and to the extent provided in the 
related Trust Issuance Certificate or Series Supplement, if any. In no event, 
however, shall any Notes be redeemable unless the Rating Agency Condition 
shall be satisfied with respect to each Rating Agency other than Moody's, to 
which prior written notice of such redemption shall have been given, with 
respect to any Notes which remain Outstanding after such redemption.  The 
redemption price in any case shall be equal to the outstanding principal 
amount of the Notes to be redeemed plus accrued and unpaid interest thereon 
at the Note Interest Rate to the Optional Redemption Date (such price being 
called the "Optional Redemption Price"). If the Note Issuer shall elect to 
redeem the Notes of a Series pursuant to this Section 10.01, it shall furnish 
written notice (which notice shall state all items listed in Section 10.02) 
of such election to the Indenture Trustee and the 


                                      67

<PAGE>

Rating Agencies not more than 50 and not less than 25 days prior to the 
Optional Redemption Date and shall deposit with the Indenture Trustee not 
later than one Business Day prior to the Optional Redemption Date the 
Optional Redemption Price of the Notes to be redeemed whereupon all such 
Notes shall be due and payable on the Optional Redemption Date upon the 
furnishing of a notice complying with Section 10.02 hereof to each Holder of 
the Notes of such Series pursuant to this Section 10.01.

            SECTION 10.02. FORM OF OPTIONAL REDEMPTION NOTICE.  Unless 
otherwise specified in the Trust Issuance Certificate or Series Supplement, 
if any, relating to a Series of Notes, notice of redemption under Section 
10.01 hereof shall be given by the Indenture Trustee by first-class mail, 
postage prepaid, mailed not less than five days nor more than 25 days prior 
to the applicable Optional Redemption Date to each Holder of Notes to be 
redeemed, as of the close of business on the Record Date preceding the 
applicable Optional Redemption Date at such Holder's address appearing in the 
Note Register.

            All notices of redemption shall state:

            (1)    the Optional Redemption Date;

            (2)    the Optional Redemption Price;

            (3)    the place where such Notes are to be surrendered for payment
                   of the Optional Redemption Price (which shall be the office
                   or agency of the Note Issuer to be maintained as provided in
                   Section 3.02 hereof);

            (4)    the CUSIP number, if applicable; and

            (5)    the principal amount of Notes to be redeemed.

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

            SECTION 10.03. NOTES PAYABLE ON OPTIONAL REDEMPTION DATE. Notice 
of redemption having been given as provided in Section 10.02 hereof; the 
Notes to be redeemed shall on the Optional Redemption Date become due and 
payable at the Optional Redemption Price and (unless the Note Issuer shall 
default in the payment of the Optional Redemption Price) no interest shall 
accrue on the Optional Redemption Price for any period after the date to 
which accrued interest is calculated for purposes of calculating the Optional 
Redemption Price.

                                 MISCELLANEOUS

            SECTION 11.01. COMPLIANCE CERTIFICATES AND OPINIONS, ETC.

            (a)    Upon any application or request by the Note Issuer to the 
Indenture Trustee to take any action under any provision of this Indenture, 
the Note Issuer shall furnish to the Indenture Trustee (i) an Officer's 
Certificate stating that all conditions precedent, if any, provided for in 
this Indenture relating to the proposed action have been complied with, (ii) 
an Opinion of Counsel stating that in the opinion of such counsel all such 
conditions precedent, if any, have been complied with and (iii) (if required 
by the TIA) an Independent Certificate from a firm of certified public 
accountants meeting the applicable requirements of this Section, except that, 
in the case of any such application or request as to which the furnishing of 
such documents is specifically required by any provision of this Indenture, 
no additional certificate or opinion need be furnished.

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

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

            (ii)   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;

            (iii)  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

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

            (b)    (i)    Prior to the deposit of any Note Collateral or 
other property or securities with the Indenture Trustee that is to be made 
the basis for the release of any property or securities subject to the lien 
of this Indenture, the Note Issuer shall, in addition to any obligation 
imposed in Section 11.01(a) or elsewhere in this Indenture, furnish to the 
Indenture Trustee an Officer's Certificate certifying or stating the opinion 
of each person signing such certificate as to the fair value (within 90 days 
of such deposit) to the Note Issuer of the Note Collateral or other property 
or securities to be so deposited.


                                      69

<PAGE>

                   (ii)   Whenever the Note Issuer is required to furnish to 
the Indenture Trustee an Officer's Certificate certifying or stating the 
opinion of any signer thereof as to the matters described in clause (i) 
above, the Note Issuer shall also deliver to the Indenture Trustee an 
Independent Certificate as to the same matters, if the fair value to the Note 
Issuer of the securities to be so deposited and of all other such securities 
made the basis of any such withdrawal or release since the commencement of 
the then-current fiscal year of the Note Issuer, as set forth in the 
certificates delivered pursuant to clause (i) above and this clause (ii), is 
ten percent or more of the Outstanding Amount of the Notes of all Series, but 
such a certificate need not be furnished with respect to any securities so 
deposited, if the fair value thereof to the Note Issuer as set forth in the 
related Officer's Certificate is less than the lesser of (A) $25,000 or (B) 
one percent of the Outstanding Amount of the Notes of all Series.

                   (iii)  Whenever any property or securities are to be 
released from the lien of this Indenture other than pursuant to Section 
8.02(d), the Note Issuer shall also furnish to the Indenture Trustee an 
Officer's Certificate certifying or stating the opinion of each person 
signing such certificate as to the fair value (within 90 days of such 
release) of the property or securities proposed to be released and stating 
that in the opinion of such person the proposed release will not impair the 
security under this Indenture in contravention of the provisions hereof

                   (iv)   Whenever the Note Issuer is required to furnish to 
the Indenture Trustee an Officer's Certificate certifying or stating the 
opinion of any signatory thereof as to the matters described in clause (iii) 
above, the Note Issuer shall also furnish to the Indenture Trustee an 
Independent Certificate as to the same matters if the fair value of the 
property or securities and of all other property with respect to such Series, 
or securities released from the lien of this Indenture (other than pursuant 
to Section 8.02(d) hereof) since the commencement of the then-current 
calendar year, as set forth in the certificates required by clause (iii) 
above and this clause (iv), equals 10 percent or more of the Outstanding 
Amount of the Notes of all Series, but such certificate need not be furnished 
in the case of any release of property or securities if the fair value 
thereof as set forth in the related Officer's Certificate is less than the 
lesser of (A) $25,000 or (B) one percent of the then Outstanding Amount of 
the Notes of all Series.

                   (v)    Notwithstanding Section 2.16 or any other provision 
of this Section 11.01, the Indenture Trustee may (A) collect, liquidate, sell 
or otherwise dispose of the Intangible Transition Property and the other Note 
Collateral as and to the extent permitted or required by the Basic Documents 
and (B) make cash payments out of the Collection Account as and to the extent 
permitted or required by the Basic Documents.

            SECTION 11.02. FORM OF DOCUMENTS DELIVERED TO INDENTURE 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 


                                      70

<PAGE>

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 a Responsible 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 a Responsible 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 Grantee, 
the Note Issuer or the Administrator, stating that the information with 
respect to such factual matters is in the possession of the Servicer, the 
Grantee, 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 Indenture, in connection with any application or 
certificate or report to the Indenture Trustee, it is provided that the Note 
Issuer shall deliver any document as a 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 Indenture 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 Indenture, they may, but need not, be consolidated and 
form one instrument.

            SECTION 11.03. ACTS OF HOLDERS.

            (a)    Any request, demand, authorization, direction, notice, 
consent, waiver or other action provided by this Indenture to be given or 
taken by Holders may be embodied in and evidenced by one or more instruments 
of substantially similar tenor signed by such Holders 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 Indenture 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 Holders signing such instrument or instruments. Proof of 
execution of any such instrument or of a writing appointing any such agent 
shall be sufficient for any purpose of this Indenture and (subject to Section 
6.01) conclusive in favor of the Indenture Trustee and the Note Issuer, if 
made in the manner provided in this Section.


                                      71

<PAGE>

            (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 Indenture 
Trustee deems sufficient.

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

            (d)    Any request, demand, authorization, direction, notice, 
consent, waiver or other action by the Holder of any Notes shall bind the 
Holder of every Note 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 Indenture Trustee or the Note Issuer in reliance thereon, 
whether or not notation of such action is made upon such Note.

            SECTION 11.04. NOTICES, ETC. TO INDENTURE TRUSTEE, NOTE ISSUER 
AND RATING AGENCIES.

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

                   (i)    the Indenture Trustee by any Holder or by the
     Note Issuer shall be sufficient for every purpose hereunder if made,
     given, furnished or filed in writing by facsimile transmission,
     first-class mail or overnight delivery service to or with the
     Indenture Trustee at its Corporate Trust Office, or

                   (ii)   the Note Issuer by the Indenture Trustee or by
     any Holder shall be sufficient for every purpose hereunder if in
     writing and mailed, first-class, postage prepaid, to the Note Issuer
     addressed to: Illinois Power Special Purpose Trust, Attention: Eric B.
     Weekes or at any other address previously furnished in writing to the
     Indenture Trustee by the Note Issuer. The Note Issuer shall promptly
     transmit any notice received by it from the Holders to the Indenture
     Trustee.

            (b)    Notices required to be given to the Rating Agencies by the 
Note Issuer or the Indenture Trustee shall be in writing, personally 
delivered or mailed by certified mail, return receipt requested to (i) in the 
case of Moody's, to: Moody's Investors Service, Inc., ABS Monitoring 
Department, 99 Church Street, New York, New York 10007, (ii) in the case of 
Standard & Poor's, to: Standard & Poor's Corporation, 26 Broadway (10th 
Floor), New York, New York 10004, Attention of Asset Backed Surveillance 
Department, (iii) in the case of Fitch IBCA, to Fitch IBCA, Inc., One State 
Street Plaza, New York, New York 10004, Attention: ABS Surveillance, and (iv) 
in the case of Duff & Phelps, to Duff & Phelps Credit Rating Co., 17 State 
Street, 12th Floor, New York, New York 10004, Attention: Asset- Backed 
Monitoring Group.

            SECTION 11.05. NOTICES TO HOLDERS WAIVER.  Where this 
Indenture provides for notice to Holders 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 Holder affected 


                                      72

<PAGE>

by such event, at such Holder's address as it appears on the Note Register, 
not later than the latest date, and not earlier than the earliest date, 
prescribed for the giving of such notice. In any case where notice to Holders 
is given by mail, neither the failure to mail such notice nor any defect in 
any notice so mailed to any particular Holder shall affect the sufficiency of 
such notice with respect to other Holders, and any notice that is mailed in 
the manner herein provided shall conclusively be presumed to have been duly 
given.

            Where this Indenture provides for notice in any manner, such 
notice may be waived in writing by any Person entitled to receive such 
notice, either before or after the event, and such waiver shall be the 
equivalent of such notice. Waivers of notice by Holders shall be filed with 
the Indenture Trustee but such filing shall not be a condition precedent to 
the validity of any action taken in reliance upon such 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 Holders when such notice is 
required to be given pursuant to any provision of this Indenture, then any 
manner of giving such notice as shall be satisfactory to the Indenture 
Trustee shall be deemed to be a sufficient giving of such notice.

            Where this 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 Indenture by any of the provisions of 
the Trust Indenture Act, such required provision shall control.

            The provisions of TIA Sections 310 through 317 that impose duties 
on any person (including the provisions automatically deemed included herein 
unless expressly excluded by this Indenture) are a part of and govern this 
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 Indenture and the Notes by the Note Issuer shall bind its 
successors and assigns, whether so expressed or not. All agreements of the 
Indenture Trustee in this Indenture shall bind its successors.


                                      73

            SECTION 11.09. SEPARABILITY.  In case any provision in this 
Indenture or in the Notes shall be invalid, illegal or unenforceable, the 
validity, legality, and enforceability of the remaining provisions shall not 
in any way be affected or impaired thereby.

            SECTION 11.10. BENEFITS OF INDENTURE.  Nothing in this Indenture 
or in the Notes, express or implied, shall give to any Person, other than the 
parties hereto and their successors hereunder, and the Holders, and any other 
party secured hereunder, and any other Person with an ownership interest in 
any part of the Note Collateral, any benefit or any legal or equitable right, 
remedy or claim under this 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 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 INDENTURE SHALL BE CONSTRUED 
IN ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS, 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.

            SECTION 11.13. COUNTERPARTS.  This 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 INDENTURE.  If this 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 Indenture Trustee or 
any other counsel reasonably acceptable to the Indenture Trustee) to the 
effect that such recording is necessary either for the protection of the 
Holders or any other Person secured hereunder or for the enforcement of any 
right or remedy granted to the Indenture Trustee under this 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 Indenture Trustee on the Notes or under this Indenture or any certificate 
or other writing delivered in connection herewith or therewith, against (i) 
the Indenture Trustee or the Delaware Trustee in its respective individual 
capacity, (ii) any owner of a beneficial interest in the Note Issuer 
(including the Grantee and Illinois Power) or (iii) any partner, owner, 
beneficiary, agent, officer, or employee of the Indenture Trustee or the 
Delaware Trustee in its respective individual capacity, any holder of a 
beneficial interest in the Indenture Trustee or of any successor or assign of 
any of them in their respective individual or corporate capacities, except as 
any such Person may have expressly 


                                      74

agreed (it being understood that none of the Indenture Trustee, the Delaware 
Trustee, the Grantee and Illinois Power have any such obligations in their 
respective individual or corporate capacities).

            SECTION 11.16. NO RECOURSE TO NOTE ISSUER.  Notwithstanding any 
provision of this Indenture or any Trust Issuance Certificate or any Series 
Supplement to the contrary, Holders shall have no recourse against the Note 
Issuer, but shall look only to the Note Collateral with respect to any 
amounts due to the Holders hereunder and under the Notes.

            SECTION 11.17. INSPECTION.   The Note Issuer agrees that, on 
reasonable prior notice, it will permit any representative of the Indenture 
Trustee, during the Note Issuer's normal business hours, to 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 Issuer's officers, employees, 
and Independent certified public accountants, all at such reasonable times 
and as often as may be reasonably requested. The Indenture 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 Indenture 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 Indenture Trustee from sources 
other than the Note Issuer, provided such parties are rightfully in 
possession of such information, (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 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 Indenture 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.

            SECTION 11.18. NO PETITION.  The Indenture Trustee, by entering 
into this Indenture, and each Holder, by accepting a Note (or interest 
therein) issued hereunder, hereby covenant and agree that they shall not, 
prior to the date which is one year and one day after the termination of the 
Indenture, acquiesce, petition or otherwise invoke or cause the Grantee,  the 
Note Issuer or the Delaware Trustee to invoke the process of any court or 
government authority for the purpose of commencing or sustaining a case 
against the Grantee, the Note Issuer or the Delaware Trustee under any 
insolvency law or appointing a receiver, liquidator, assignee, trustee, 
custodian, sequestrator or other similar official of the Grantee, the Note 
Issuer or the Delaware Trustee or any substantial part of its respective 
property, or ordering the winding up or liquidation of the affairs of the 
Grantee, the Note Issuer or the Delaware Trustee.

            This Series [     ], Class [ - ] Note is one of a duly authorized
issue of Notes of the Note Issuer (herein called the "Notes"), issued and to be
issued in one or more Series, which Series are issuable in one or more Classes,
and the Series [     ] Notes consists of [seven] Classes, including this Class 
[ - ] Note (herein called the "Class [ - ] Notes"), all issued and to be issued
under an Indenture dated as of December 1, 1998 (the "Indenture"), between the
Note Issuer and Harris Trust and Savings Bank, as Indenture Trustee (the
"Indenture Trustee," which term includes any successor trustee under the
Indenture), to which 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 Indenture Trustee and the Holders of the
Notes. All terms used in this Class [ - ] Note that are defined in the
Indenture, as supplemented or amended, shall have the meanings assigned to them
in the Indenture.

            The Class [ - ] Notes, the other Classes of Series [     ] Notes
(all of such Classes being referred to herein as "Series [     ] Notes") and any
other Series of Notes issued by the Note Issuer are and will be equally and
ratably secured by the Note Collateral pledged as security therefor as provided
in the Indenture.

            The principal of this Class [  ] 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
the preceding Payment Date (after giving effect to all payments of principal, if
any, made on the preceding Payment Date) has been reduced to the principal
balance specified in the Expected Amortization Schedule which is attached to the
related Trust Issuance Certificate or Series Supplement, if any, as Schedule A,
unless payable earlier either because (x) an Event of Default shall have
occurred and be continuing and the Indenture Trustee or the Holders of Notes
representing not less than a majority of the Outstanding Amount of the Notes of
all Series have declared the Notes of all Series to be immediately due and
payable in accordance with Section 5.02 of the Indenture or (y) the Note Issuer,
at its option, shall have called for the redemption of the Series [     ] Notes
pursuant to Section 10.01 of the Indenture. 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 Indenture.  The entire unpaid
principal amount of this Class [ - ] Note shall be due and payable on the
earlier of the Final Maturity Date hereof and the Optional Redemption Date, if
any.  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
Indenture Trustee or the Holders of the Notes representing not less than a
majority of the Outstanding Amount of the Notes of all Series have declared the
Notes of all Series to be immediately due and payable in the manner provided in
Section 5.02 of the Indenture.  All

more Predecessor Notes) on the Note Register as of the close of business on the

provided below.  Such checks shall be mailed to the Person entitled thereto at

Date, then the Indenture 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 [ - ] Note
and shall specify the place where this Class [ - ] 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 Indenture, the Class [ - ] 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 Class
[ - ] Notes has been reduced to less than five percent of the initial principal
balance thereof.

            This Note is a transitional funding instrument as such term is
defined in the Funding Law.  Principal and interest due and payable on this Note
are payable from and secured primarily by intangible transition property created
and established by a transitional funding order 

                                      A-6

<PAGE>

obtained from the Illinois Commerce Commission pursuant to the Funding Law.  
Intangible transition property consists of the right to impose and collect 
certain charges (defined in the Funding Law as "instrument funding charges") 
to be included in regular electric utility bills of existing and future 
electric service customers of Illinois Power Company, an Illinois electric 
utility.

            The Funding Law provides that: "The State [of Illinois] pledges to
and agrees with the holders of any transitional funding instruments who may
enter into contracts with an electric utility, grantee, assignee or issuer
pursuant to this Article XVIII [of the Public Utility Act] that the State [of
Illinois] will not in any way limit, alter, impair or reduce the value of
intangible transition property created by, or instrument funding charges
approved by, a transitional funding order so as to impair the terms of any
contract made by such electric utility, grantee, assignee or issuer with such
holders or in any way impair the rights and remedies of such holders until the
pertinent grantee instruments or, if the related transitional funding order does
not provide for the issuance of grantee instruments, the pertinent transitional
funding instruments and interest, premium and other fees, costs and charges
related thereto, as the case may be, are fully paid and discharged.  Electric
utilities, grantees and issuers are authorized to include these pledges and
agreements of the State [of Illinois] in any contract with the holders of
transitional funding instruments or with any assignees pursuant to this Article
XVIII [of the Public Utility Act] and any assignees are similarly authorized to
include these pledges and agreements of the State [of Illinois] in any contract
with any issuer, holder or any other assignee.  Nothing in this Article XVIII
[of the Public Utility Act] shall preclude the State of Illinois from requiring
adjustments as may otherwise be allowed by law to the electric utility's base
rates, transition charges, delivery services charges, or other charges for
tariffed services, so long as any such adjustment does not directly affect or
impair any instrument funding charges previously authorized by a transitional
funding order issued by the [Illinois Commerce] Commission."

            As a result of the foregoing pledge, the State of Illinois may not,
except as provided in the succeeding sentence, in any way limit, alter, impair
or reduce the value of such intangible transition property or such instrument
funding changes in a manner substantially impairing the Note Indenture or the
rights and remedies of the Holders, until the Notes, together with interest
thereon, are fully paid and discharged.  Notwithstanding the immediately
preceding sentence, the State of Illinois would be allowed to effect a temporary
impairment of the Holders' rights if it could be shown that such impairment was
necessary to advance a significant and legitimate public purpose.

            As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Class [- ] Note may be registered on the
Note Register upon surrender of this Class  [ - ] Note for registration of
transfer at the office or agency designated by the Note Issuer pursuant to the
Indenture, duly endorsed by, or accompanied by (a) a written instrument of
transfer in form satisfactory to the Indenture 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 Program 
(MSP); (iii) The Stock Exchange Medallion Program (SEMP); or (iv) in such 
other guarantee program acceptable to the Indenture Trustee, and (b) such 
other documents as the Indenture Trustee may require, and thereupon one or 
more new Class [ - ] 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 [ - ] 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 or 9.06 of the Indenture not 
involving any transfer.

            Each Note holder, 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 Indenture Trustee on the Notes or under
the Indenture or any certificate or other writing delivered in connection
therewith, against (i) the Indenture Trustee or the Delaware Trustee in its
respective individual capacity, (ii) any owner of a beneficial interest in the
Note Issuer (including the Grantee and Illinois Power) or (iii) any partner,
owner, beneficiary, agent, officer or employee of the Indenture Trustee or the
Delaware Trustee in its respective capacity, any holder of a beneficial interest
in the Delaware Trustee or the Indenture Trustee or of any successor or assign
of the Indenture Trustee or the Delaware Trustee in any of their individual or
corporate capacities except as any such Person may have expressly agreed (it
being understood that none of the Indenture Trustee, the Delaware Trustee, the
Grantee and Illinois Power has any such obligations in their respective
individual or corporate capacities).

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

            The 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 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 Series or Class to be affected.  The Indenture also contains
provisions permitting the Holders of Notes representing specified percentages of
the Outstanding Amount of the Notes of all Series, on behalf of the Holders of
all the Notes, to waive compliance by the Note Issuer with certain provisions of
the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Class [ - ] Note
(or any one of more Predecessor Notes) shall be conclusive and binding upon such
Holder and upon all future Holders of this Class [ - ] 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 

                                      A-8

<PAGE>

upon this Class [ -  ] Note.  The Indenture also permits the Indenture 
Trustee to amend or waive certain terms and conditions set forth in the 
Indenture without the consent of Holders of the Notes issued thereunder.

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

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

            The Class [ - ] Notes are issuable only in registered form in
denominations as provided in the Indenture and the related Trust Issuance
Certificate or Series Supplement, if any, subject to certain limitations therein
set forth.

            This Class [ - ] Note, the Indenture and the related Trust Issuance
Certificate or Series Supplement, if any, shall be construed in accordance with
the laws of the State of Illinois, 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 Indenture and no provision of this Class
[ - ] Note or of the 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 [ - ] Note at the times, place, and rate, and in the coin
or currency-herein prescribed.

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

            The Note Issuer and the Indenture Trustee, by entering into this
Indenture, and the Holders and any Persons holding a beneficial interest in any
Class [ - ] Note, by acquiring any Class [ - ] Note or interest therein, (i)
express their intention that the Class [ - ] Notes qualify under applicable tax
law as indebtedness of Illinois Power secured by the Note Collateral and (ii)
unless otherwise required by appropriate taxing authorities, agree to treat the
Class [ - ] Notes as indebtedness of Illinois Power secured by the Note
Collateral for the purpose of federal income, state and local income and
franchise taxes, and any other taxes imposed upon, measured by or based upon
gross or net income.

                                  ARTICLE II

            CONVEYANCE OF 1998 TRANSITION PROPERTY AND RELATED ASSETS

     SECTION 2.01. CONVEYANCE OF 1998 TRANSITION PROPERTY AND RELATED ASSETS. 
 In consideration of the Note Issuer's delivery of $864,000,000 (less 
underwriting discounts and original issue discount) to or upon the order of 
the Grantee, the Grantee irrevocably sells, transfers, assigns, sets over and 
otherwise conveys to the Note Issuer, without recourse (subject to the 
obligations herein), all of its right, title and interest in, to and under:


                                       2

<PAGE>

     (a)    the 1998 Transition Property (such sale, transfer, assignment, 
set over and conveyance of the 1998 Transition Property includes, to the 
fullest extent permitted by the Funding Law, the assignment of all revenues, 
collections, claims, rights, payments, money or proceeds of or arising from 
the IFCs pursuant to the 1998 Funding Order and the 1998 Initial Tariff), 
including, without limitation, any contractual rights to collect IFCs from 
Customers and Allocable IFC Revenue Amounts; and

     (b)    the Related Assets.  

     Such sale, transfer, assignment, set over and conveyance is expressly 
stated to be a sale and absolute transfer, and pursuant to Section 18-108 of 
the Funding Law, shall be treated as an absolute transfer (as in a true 
sale), and not as a pledge or other financing, of the 1998 Transition 
Property.  The previous sentence is the express statement referred to in 
Section 18-108 of the Funding Law.  To the extent that, notwithstanding the 
Funding Law, the Application and the 1998 Funding Order, the foregoing sale, 
transfer, assignment, set over and conveyance is held not to be an absolute 
transfer (as in a true sale) as contemplated under Section 18-108 of the 
Funding Law, then such sale, transfer, assignment, set over and conveyance 
shall be treated as a pledge of the 1998 Transition Property and the Grantee 
shall be deemed to have granted a security interest to the Note Issuer in the 
1998 Transition Property.  The Grantee takes the position that it has no 
rights in the 1998 Transition Property to which such a security interest 
could attach because it has sold, transferred, assigned, set over or 
otherwise conveyed all rights in, to and under the 1998 Transition Property 
to the Note Issuer pursuant to Section 18-108 of the Funding Law.

     The Grantee makes the following representations and warranties, as of 
the Closing Date, on which the Note Issuer has relied in acquiring the 1998 
Transition Property and Related Assets. These representations and warranties

1998 Transition Property and Related Assets to the Note Issuer, the pledge 
thereof to the Indenture Trustee pursuant to the Indenture and the issuance 
of the Notes.

     SECTION 3.01. ORGANIZATION AND GOOD STANDING. The Grantee is duly 
organized and validly existing as a limited liability company in good

had at all relevant times, and has, the requisite power, authority and legal 
right to own the 1998 Transition Property and Related Assets.

     SECTION 3.02. DUE QUALIFICATION.  The Grantee is duly qualified to do 
business as a limited liability company 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

qualify would not be reasonably likely to have a material adverse effect on 
the Grantee's business, operations, assets, revenues or properties).

     SECTION 3.03. POWER AND AUTHORITY.  The Grantee has the requisite power 
and authority to execute and deliver this Agreement and to carry out its

assignment to the Note Issuer by all necessary company action; and the 
execution, delivery and performance of this Agreement have been duly 
authorized by the Grantee by all necessary company action.

     SECTION 3.04. BINDING OBLIGATION.  This Agreement constitutes a legal, 
valid and binding obligation of the Grantee enforceable against the Grantee 
in accordance with its terms, subject to applicable insolvency, 
reorganization, moratorium, fraudulent transfer and other similar laws 
relating to or affecting creditors' rights generally from time to time in 
effect and to general principles of equity (including, without limitation, 
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, result in any breach of any of the terms and provisions 
of, or constitute (with or without notice or lapse of time) a default under, 
the Operating Agreement or Certificate of Formation of the Grantee, or any 
indenture, agreement or other instrument to which the Grantee is a party or 
by which it shall be bound; (ii) result in the creation or imposition of any 
Lien upon any of its properties pursuant to the terms of any such indenture, 
agreement or other instrument; or (iii) violate any law or any order, rule or 
regulation applicable to the Grantee of any court or of any Federal or state 
regulatory body, administrative agency or other governmental instrumentality 
having jurisdiction over the Grantee or its properties.

     SECTION 3.06. NO PROCEEDINGS.  There are no proceedings or 
investigations pending or, to the Grantee's knowledge, threatened, before any 
court, Federal or state regulatory body, administrative agency or other 
governmental instrumentality having jurisdiction over the Grantee 


                                       5

<PAGE>

or its properties involving or relating to the Grantee or the Note Issuer or, 
to the Grantee's knowledge, any other Person: (i) asserting the invalidity of 
the Funding Law, this Agreement, any of the other Basic Documents or the 
Notes, (ii) seeking to prevent the issuance of the Notes 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 could 
reasonably be expected to materially and adversely affect the Grantee's 
performance of its obligations under, or the validity or enforceability of 
this Agreement, any of the other Basic Documents or the Notes, or (iv) which 
could reasonably be expected to adversely affect the Federal or state income 
tax attributes of the Notes.

     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 Grantee's execution and delivery of this Agreement, the 
Grantee's performance of the transactions contemplated hereby or the 
Grantee's fulfillment of the terms hereof except those that have been 
obtained or made.

     SECTION 3.08. THE 1998 TRANSITION PROPERTY AND RELATED ASSETS.

     (a)    INFORMATION.  At the Closing Date, all information provided by 
the Grantee to the Note Issuer with respect to the 1998 Transition Property 
(including the 1998 Funding Order and the 1998 Initial Tariff) and the 
Related Assets is correct in all material respects.

     (b)    TITLE.  It is the intention of the parties hereto that the 
transfer and assignment herein contemplated constitute a sale and absolute 
transfer of the 1998 Transition Property and Related Assets from the Grantee 
to the Note Issuer and that no beneficial interest in or title to the 1998 
Transition Property and Related Assets shall be part of the Grantee's estate 
in the event of the filing of a bankruptcy petition by or against the Grantee 
under any bankruptcy law.  No portion of the 1998 


                                       6

<PAGE>

Transition Property and Related Assets has been sold, transferred, assigned, 
pledged or otherwise conveyed by the Grantee to any Person other than the 
Note Issuer.  At the Closing Date, immediately prior to the sale hereunder, 
the Grantee owns the 1998 Transition Property and Related Assets, free and 
clear of all Liens and rights of any other Person, and no encumbrances, 
offsets, defenses or counterclaims exist or have been asserted with respect 
thereto.

     (c)    TRANSFER FILINGS.  At the Closing Date, the 1998 Transition 
Property and Related Assets have been validly transferred, assigned and sold 
from the Grantee to the Note Issuer, the Note Issuer owns all the 1998 
Transition Property and Related Assets, free and clear of all Liens and 
rights of any other Person (other than Liens created pursuant to the 
Indenture), and all filings to be made by the Grantee (including filings with 
the ICC under the Funding Law) necessary in any jurisdiction to give the Note 
Issuer a first priority perfected ownership interest in the 1998 Transition 
Property and Related Assets have been made.  No further action is required 
under Illinois law to maintain such first priority perfected ownership 
interest in the 1998 Transition Property.  No further action, other than any 
filings or other steps required to be taken with respect to proceeds or on 
account of events occurring after the date hereof by Sections 9-103, 9-304, 
9-306, 9-402(7) or 9-403(2)- (3) of the UCC, is required to maintain such 
first priority perfected ownership interest in the Related Assets.

     (d)    STATE PLEDGE.  The State of Illinois has agreed with the Holders, 
pursuant to Section 18-105(b) of the Funding Law, as follows:

            "(b) The State pledges to and agrees with the holders of any
     transitional funding instruments who may enter into contracts with an
     electric utility, grantee, assignee or issuer pursuant to this Article
     XVIII that the State will not in any way limit, alter, impair or
     reduce the value of intangible transition property created by, or
     instrument funding charges approved by, a transitional funding order
     so as to impair the terms of any contract made by such electric
     utility, grantee, assignee or issuer with such holders or in any way
     impair the 


                                       7

<PAGE>

     rights and remedies of such holders until the pertinent grantee 
     instruments or, if the related transitional funding order does not 
     provide for the issuance of grantee instruments, the pertinent
     transitional funding instruments and interest, premium and other costs
     and charges related thereto, as the case may be, are fully paid and
     discharged. Electric utilities, grantees and issuers are authorized to
     include these pledges and agreements of the State in any contract with
     the holders of transitional funding instruments or with any assignees
     pursuant to this Article XVIII and any assignees are similarly
     authorized to include these pledges and agreements of the State in any
     contract with any issuer, holder or any other assignee. Nothing in
     this Article XVIII shall preclude the State of Illinois from requiring
     adjustments as may otherwise be allowed by law to the electric
     utility's base rates, transition charges, delivery services charges,
     or other charges for tariffed services, so long as any such adjustment
     does not directly affect or impair any instrument funding charges
     previously authorized by a transitional funding order issued by the
     [ICC]."

As a result of the foregoing pledge, the State of Illinois may not, except as 
provided in the succeeding sentence, in any way reduce, postpone, impair or 
terminate the 1998 Transition Property in a manner substantially impairing 
the Indenture or the rights and remedies of the Holders (and consequently, 
may not revoke, reduce, postpone or terminate the 1998 Funding Order or the 
rights of the Holders to receive IFC Payments and all other proceeds of the 
1998 Transition Property), until the Notes, together with interest thereon, 
are fully paid and discharged.  Notwithstanding the immediately preceding 
sentence, the State would be allowed to effect a temporary impairment of the 
Holders' rights if it could be shown that a temporary impairment was 
necessary to advance a significant and legitimate public purpose.

     (e)    1998 FUNDING ORDER AND TARIFFS; OTHER APPROVALS.  (i) The 1998 
Funding Order pursuant to which the 1998 Transition Property has been created 
has been duly entered by the ICC, is valid and binding, is Final and is in 
full force and effect; (ii) the 1998 Initial Tariff is in full force and 
effect and is not subject to modification by the ICC except as provided under 
the Funding Law; (iii) as of the issuance of the Notes, the Notes are 
entitled to the protections provided in Section 18-104(c) of the Funding Law 
and, accordingly, the 1998 Funding Order, the 1998 Transition Property 


                                       8

<PAGE>

and the IFCs are not revocable by the ICC; (iv) the ICC may not reduce, 
postpone, impair or terminate the 1998 Transition Property, the 1998 Funding 
Order or the IFCs; (v) the process by which the 1998 Funding Order was 
adopted and approved and the 1998 Initial Tariff was filed, and the 1998 
Funding Order and the 1998 Initial Tariff themselves, comply with all 
applicable laws, rules and regulations and the ICC may not revoke, amend or 
otherwise change the 1998 Initial Tariff in any manner which would defeat the 
expectations of the Holders to receive IFC Payments on a timely basis; and 
(vi) 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 grant of the 1998 Transition Property, except those that have been 
obtained or made.

     (f)    ASSUMPTIONS.  At the Closing Date, the assumptions used in 
calculating the IFCs are reasonable and made in good faith.

     (g)    CREATION OF 1998 TRANSITION PROPERTY.  Upon the effectiveness of 
the 1998 Initial Tariff: (i) all of the 1998 Transition Property constitutes 
a current property right vested in the Grantee; (ii) the 1998 Transition 
Property includes, without limitation, (A) the right, title and interest in 
and to the IFCs authorized under the 1998 Funding Order, as adjusted from 
time to time, (B) the right, title and interest in and to all revenues, 
collections, claims, payments, money or proceeds of or arising from the IFCs 
set forth in the 1998 Initial Tariff, and (C) all rights to compel Illinois 
Power, as Servicer (or any successor), to file for and obtain adjustments to 
the IFCs pursuant to the 1998 Funding Order; and (iii) the Grantee is 
entitled to impose and collect the IFCs described in the 1998 Funding Order 
and the 1998 Initial Tariff in an aggregate amount equal to the principal 
amount of the Notes, all interest thereon, all amounts required to be 
deposited in the Reserve Subaccount, 


                                       9

<PAGE>

the Overcollateralization Subaccount and the Capital Subaccount, and all 
related fees, costs and expenses in respect of the Notes until they have been 
paid in full, subject only to the $1.634 billion limitation set forth in the 
1998 Funding Order as the maximum dollar amount of 1998 Transition Property 
created thereunder.

     (h)    PROPERTY OF GRANTEE.  To the fullest extent permitted by the 
Funding Law and all other applicable law, the 1998 Transition Property and 
the right to impose and collect IFCs contemplated thereunder constitute 
property rights of the Grantee and its assigns, including the Note Issuer and 
its assigns (including the Indenture Trustee on behalf of the Holders), which 
property has been placed beyond the reach of Illinois Power and its 
creditors, as in a true sale, and which property rights may not be limited, 
altered, impaired, reduced or otherwise terminated by any subsequent actions 
of Illinois Power or any third party and which shall, to the full extent 
permitted by law, be enforceable against Illinois Power, its successors and 
assigns, and all other third parties (including judicial lien creditors) 
claiming an interest therein by or through Illinois Power or its successors 
and assigns.

     (i)    NATURE OF REPRESENTATIONS AND WARRANTIES.  The representations 
and warranties set forth in this SECTION 3.08, insofar as they involve 
conclusions of law, are made not on the basis that the Grantee purports to be 
a legal expert or to be rendering legal advice, but rather to reflect the 
parties' good faith understanding of the legal basis on which the parties are 
entering into this Agreement and the other Basic Documents and the basis on 
which the Holders are purchasing the Notes, and to reflect the parties' 
agreement that, if such understanding turns out to be incorrect or 
inaccurate, the Grantee will be obligated to indemnify the Note Issuer and 
its permitted assigns, and that the Note Issuer and its permitted assigns 
will be entitled to enforce any rights and remedies 


                                      10

<PAGE>

under the documents, on account of such inaccuracy to the same extent as if 
the Grantee had breached any other representations or warranties hereunder.

                                  ARTICLE IV

                            COVENANTS OF THE GRANTEE

     SECTION 4.01. CORPORATE EXISTENCE.  So long as any of the Notes are 
outstanding, the Grantee (a) will keep in full force and effect its 
existence, rights and franchises as a limited liability company under the 
laws of the State of Delaware (unless it becomes, or any successor Grantee 
hereunder is or becomes, organized under the laws of any other State or of 
the United States of America, in which case the Grantee will keep in full 
effect its existence, rights and franchises under the laws of such other 
jurisdiction), (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 Basic Documents to which the Grantee is 
a party and each other instrument or agreement necessary or appropriate to 
the proper administration of this Agreement and the transactions contemplated 
hereby and (c) at all times hereafter, the Grantee will not elect nor cause 
nor permit the Note Issuer to elect to be classified as an association 
taxable as a corporation for federal income tax purposes.

     SECTION 4.02. NO LIENS.  Except for the conveyances hereunder, the 
Grantee will not sell, pledge, assign or transfer to any other Person, or 
grant, create, incur, assume, suffer to exist or otherwise assert any Lien 
on, any of the 1998 Transition Property or Related Assets, or any interest 
therein, and the Grantee shall defend the right, title and interest of the 
Note Issuer and the Indenture 

 
                                      11

<PAGE>

Trustee in, to and under the 1998 Transition Property and Related Assets, 
against all claims of third parties claiming through or under the Grantee.

     SECTION 4.03. DELIVERY OF COLLECTIONS.  If the Grantee receives 
collections in respect of the IFCs or the proceeds thereof, or in replacement 
therefor, including, without limitation, any Allocable IFC Revenue Amounts, 
the Grantee agrees to hold such payments in trust for the Servicer and to pay 
the Servicer all payments received by the Grantee in respect thereof as soon 
as practicable after receipt thereof by the Grantee, but in no event later 
than two Business Days after such receipt.

     SECTION 4.04. NOTICE OF LIENS.  The Grantee shall notify the Note Issuer 
and the Indenture Trustee in writing promptly after becoming aware of any 
Lien on any of the 1998 Transition Property or Related Assets other than the 
conveyances hereunder and under the Indenture.

     SECTION 4.05. COMPLIANCE WITH LAW.  The Grantee shall comply with its 
organizational or governing documents and all laws, treaties, rules, 
regulations and determinations of any governmental instrumentality applicable 
to it, to the extent that failure to so comply would not materially adversely 
affect the Note Issuer's or the Indenture Trustee's interests in the 1998 
Transition Property or Related Assets or under any of the Basic Documents or 
the Grantee'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 THE 1998 TRANSITION PROPERTY, RELATED 
ASSETS AND THE NOTES.

     (a)    So long as any of the Notes are outstanding, the Grantee shall 
indicate in its financial statements that the Note Issuer and not the Grantee 
owns the 1998 Transition Property and the Related Assets.


                                      12

<PAGE>

     (b)    So long as any of the Notes are outstanding, the Grantee shall 
not own or purchase any Notes.

     (c)    The Grantee agrees that upon its sale of the 1998 Transition 
Property and Related Assets to the Note Issuer pursuant to this Agreement, 
(i) to the fullest extent permitted by law, including applicable ICC 
Regulations, the Note Issuer shall have all of the rights of the owner of the 
1998 Transition Property (including all of the rights originally held by the 
Grantee with respect to the 1998 Transition Property and Related Assets), 
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 or third party collection agent, including any ARES, in respect 
of the 1998 Transition Property, notwithstanding any objection or direction 
to the contrary by the Grantee and (ii) any payment by any Customer or third 
party collection agent, including any ARES, to the Note Issuer (or to the 
Servicer for the benefit of the Note Issuer) shall discharge such Customer's 
or third party's obligations in respect of the 1998 Transition Property to 
the extent of such payment, notwithstanding any objection or direction to the 
contrary by the Grantee.

     (d)    So long as any of the Notes are outstanding, (i) except with 
respect to federal and other applicable taxes, the Grantee shall not make any 
statement or reference in respect of the 1998 Transition Property or the 
Related Assets that is inconsistent with the ownership interest of the Note 
Issuer therein, and (ii) the Grantee shall not take any action in respect of 
the 1998 Transition Property or the Related Assets except as otherwise 
contemplated by the Basic Documents.

     SECTION 4.07. PROTECTION OF TITLE.  The Grantee shall execute and file 
such filings, including filings with the ICC pursuant to the Funding Law, 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, 


                                      13

<PAGE>

and protect the interests of the Note Issuer in the 1998 Transition Property 
and Related Assets, including all filings required under the Funding Law 
relating to the transfer of the ownership or security interest in the 1998 
Transition Property by the Grantee to the Note Issuer.  The Grantee 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, promptly 
following such filing.  The Grantee shall institute any action or proceeding 
necessary to compel performance by the ICC or the State of Illinois of any of 
their obligations or duties under the Funding Law, the 1998 Funding Order, 
the 1998 Initial Tariff or any amendatory tariff filed pursuant to Section 
18-104(k) of the Funding Law, and the Grantee 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 protect the Note Issuer and 
the Holders 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 will be payable by the Grantee. The Grantee designates the Note 
Issuer as its agent and attorney-in-fact to execute any filings with the ICC, 
financing statements, continuation statements or other instruments required 
by the Note Issuer pursuant to this Section, it being understood that the 
Note Issuer shall have no obligation to execute any such instruments.

     SECTION 4.08. NONPETITION COVENANTS.  Notwithstanding any prior 
termination of this Agreement or the Indenture, but subject to the ICC's 
right to order the sequestration and payment of revenues arising with respect 
to the 1998 Transition Property notwithstanding any bankruptcy, 
reorganization or other insolvency proceedings with respect to Illinois 
Power, the Grantee, the Note Issuer or any other grantee or assignee of the 
1998 Transition Property pursuant to Section 18-


                                      14

<PAGE>

107(c)(4) of the Funding Law, the Grantee shall not, prior to the date which 
is one year and one day after the termination of the Indenture, acquiesce, 
petition or otherwise invoke or cause or join with any other Person to invoke 
the process of any court or governmental authority for the purpose of 
commencing or sustaining a case against the Note Issuer under any Federal or 
state bankruptcy, insolvency or similar law or appointing a receiver, 
liquidator, assignee, trustee, custodian, sequestrator or other similar 
official of or for 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 
Grantee 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 1998 Transition Property or Related Assets; provided that no such 
tax need be paid if the Grantee or one of its subsidiaries is contesting the 
same in good faith by appropriate proceedings promptly instituted and 
diligently conducted and if the Grantee or such subsidiary has established

     AGREEMENT RELATING TO GRANT OF INTANGIBLE TRANSITION PROPERTY (as the 
same may be hereafter amended, supplemented or otherwise modified from time 
to time, this "Agreement") dated as of December 1, 1998, between ILLINOIS 
POWER COMPANY, an Illinois corporation ("Illinois Power"), and ILLINOIS POWER 
SECURITIZATION LIMITED LIABILITY COMPANY, a Delaware limited liability 
company (the "Grantee").

     WHEREAS, Illinois Power filed the Application with the ICC pursuant to 
Section 18-103 of the Funding Law requesting the issuance of a transitional 
funding order;

     WHEREAS, Illinois Power requested in the Application that the 
transitional funding order (i) establish, create and grant rights, in favor

Section 18-102 of the Funding Law) in the aggregate amount of $1,634,000,000; 
and (ii) establish and create "instrument funding charges" as defined in 
Section 18-102 of the Funding Law, granting the right to impose and receive 
certain non-bypassable charges expressed in cents per kilowatt hour from and 
after the effective date of the associated tariff;

     WHEREAS, the ICC issued the 1998 Funding Order on September 10, 1998, 
which created and established the intangible transition property requested by 
Illinois Power in the Application;

     WHEREAS, the 1998 Funding Order granted to and vested in the Grantee, as 
current and original property rights, and not by assignment from Illinois 
Power, all right, title and interest to impose and receive the IFCs 
authorized by and under the 1998 Funding Order and all related revenues, 
collections, claims, payments, money or proceeds thereof, including all 
right, title and interest of the Grantee in, to and under the 1998 Funding 
Order; and

     WHEREAS, the Grantee has agreed (i) to transfer the 1998 Transition 
Property to the Note Issuer pursuant to the Sale Agreement, and (ii) to pay 
Illinois Power the net proceeds received by the Grantee from the Note Issuer 
in connection with such transfer; 

                                       
<PAGE>

     NOW, THEREFORE, in consideration of the premises and the mutual 
covenants herein contained, the parties hereto agree as follows:

                                   ARTICLE I

                                  DEFINITIONS

     SECTION 1.01. DEFINITIONS.  Capitalized terms used herein and not 
otherwise defined herein have the meanings assigned to them in that certain 
Indenture (including Appendix A thereto) dated as of the date hereof, between

and Savings Bank, as the Indenture Trustee, as the same may be amended, 
supplemented or otherwise modified from time to time.

     SECTION 1.02. OTHER DEFINITIONAL PROVISIONS.

     (a)    "AGREEMENT" shall have the meaning set forth in the preamble 
hereto.

     (b)    Non-capitalized terms used herein which are defined in the Public 
Utilities Act shall, as the context requires, have the meanings assigned to 
such terms in the Public Utilities Act, but without giving effect to 
amendments to the Public Utilities Act after the date hereof which have a 
material adverse effect on the Note Issuer or the Holders.

     (c)    All terms defined in this Agreement shall have the defined 
meaning when used in any certificate or other document made or delivered 
pursuant hereto unless otherwise defined therein.

     (d)    The words "hereof" "herein," "hereunder" and words of similar

well as to the feminine and neuter forms of such terms.

                                       
                                   ARTICLE II

                          GRANT OF TRANSITION PROPERTY

     SECTION 2.01. GRANT OF TRANSITION PROPERTY.  In consideration of 
Illinois Power's actions in requesting that the 1998 Transition Property be 
created and vested in the Grantee, the Grantee agrees to remit to Illinois 
Power the net proceeds remitted to it by the Note Issuer from the sale of the 
Notes.  To the extent that, notwithstanding the Funding Law, the Application 
and the 1998 Funding Order, applicable law provides that Illinois Power has 
any interest in the 1998 Transition Property or any part thereof, Illinois 
Power hereby, effective upon the effectiveness of the 1998 Initial Tariff, 
sells, transfers, assigns, sets over and otherwise conveys to the Grantee 
without recourse (subject to the obligations herein) all of Illinois Power's 
right, title and interest, if any, in, to and under the 1998 Transition 
Property, whether such 1998 Transition Property is fixed, contingent, 
liquidated, unliquidated, material or immaterial and such sale, transfer, 
assignment, set over and conveyance shall include, to the fullest extent 
permitted by the Funding Law, the assignment of all revenues, collections, 
claims, rights, payments, money or proceeds of or arising from the IFCs 
pursuant to the 1998 Funding Order and the 1998 Initial Tariff, including, 
without limitation, any contractual rights to collect IFCs from Customers and 
Allocable IFC Revenue 

                                       3
<PAGE>

Amounts).  Such sale, transfer, assignment, set over and conveyance by 
Illinois Power is expressly stated to be a present absolute transfer, and 
pursuant to Section 18-108 of the Funding Law, shall be treated as a present 
absolute transfer (as in a true sale), and not as a pledge or other 
financing, of the 1998 Transition Property. The previous sentence is the 
express statement referred to in Section 18-108 of the Funding Law.  To the 
extent that, notwithstanding the Funding Law, the Application and the 1998 
Funding Order, Illinois Power is deemed to have any interest in the 1998 
Transition Property or any part thereof under applicable law, and if the 
foregoing sale, transfer, assignment, set over and conveyance is held not to 
be an absolute transfer (as in a true sale) as contemplated under Section 
18-108 of the Funding Law, then such sale, transfer, assignment, set over and 
conveyance shall be treated as a pledge of the 1998 Transition Property and 
Illinois Power shall be deemed to have granted a security interest to the 
Grantee in the 1998 Transition Property and the proceeds thereof.


                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF ILLINOIS POWER

     Illinois Power makes the following representations and warranties, as of 
the Closing Date, on which the Grantee has relied in selling the 1998

or any part thereof, the sale, transfer, assignment, set over and conveyance 
by Illinois Power contemplated hereby, (iii) the sale, transfer, assignment, 
set over and conveyance of the 1998 Transition Property and Related Assets to 
the Note

business, operations, assets, revenues or properties).

     SECTION 3.03. POWER AND AUTHORITY.  Illinois Power has the requisite 
power and authority to execute and deliver this Agreement and to carry out

<PAGE>

subject to applicable insolvency, reorganization, moratorium, fraudulent 
transfer and other similar laws relating to or affecting creditors' rights 
generally from time to time in effect and to general principles of equity 
(including, without limitation, 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, result in any breach of any of the terms and provisions 
of, or constitute (with or without notice or lapse of time) a default under, 
the Articles of Incorporation or by-laws of Illinois Power, or any indenture, 
agreement or other instrument to which Illinois Power is a party or by which 
it shall be bound; (ii) result in the creation or imposition of any Lien upon 
any of its properties pursuant to the terms of any such indenture, agreement 
or other instrument; or (iii) violate any law or any order, rule or 
regulation applicable to Illinois Power of any court or of any Federal or 
state regulatory body, administrative agency or other governmental 
instrumentality having jurisdiction over Illinois Power or its properties.

     SECTION 3.06. NO PROCEEDINGS.  There are no proceedings or 
investigations pending or, to Illinois Power's knowledge, threatened, before 
any court, Federal or state regulatory body, administrative agency or other 
governmental instrumentality having jurisdiction over Illinois Power or its 
properties involving or relating to Illinois Power or the Grantee or to 
Illinois Power's knowledge, any other Person: (i) asserting the invalidity of 
the Funding Law, this Agreement, any of the other Basic Documents or the 
Notes, (ii) seeking to prevent the grant of the 1998 Transition Property to

determination or ruling that could

                                       6
<PAGE>

reasonably be expected to materially and adversely affect Illinois Power's 
performance of its obligations under, or the validity or enforceability of, 
this Agreement, any of the other Basic Documents or the Notes, or (iv) which 
could reasonably be expected to adversely affect the Federal or state income 
tax attributes of the Notes.

     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 Illinois Power's execution and delivery of this Agreement, 
Illinois Power's performance of the transactions contemplated hereby or 
Illinois Power's fulfillment of the terms hereof, except those that have been 
obtained or made (it being understood that Illinois Power nonetheless has 
ongoing legal obligations to make future filings with the ICC relating to 
Illinois Power's use of proceeds from the transactions contemplated hereby 
and the final terms of each Series of Notes issued pursuant to the Indenture).

     SECTION 3.08. THE 1998 TRANSITION PROPERTY.

     (a)    INFORMATION.  All information provided by Illinois Power to the 
Grantee with respect to the 1998 Transition Property (including the 1998 
Funding Order and the 1998 Initial Tariff) is correct in all material 
respects.

     (b)    TITLE.  It is the intention of the parties hereto that the 
vesting of the 1998 Transition Property in the Grantee as contemplated by the 
1998 Funding Order shall be irrevocable and enforceable against Illinois 
Power and its successors and that no interest in or title to the 1998 
Transition Property shall be part of Illinois Power's estate in the event of 
the filing of a bankruptcy petition by or against Illinois Power under any 
bankruptcy law. Accordingly, Illinois Power reaffirms that it has no right, 
title or interest in and to the 1998 Transition Property and any sale, 

                                       7
<PAGE>

transfer, assignment, set over and conveyance which may nonetheless be 
contemplated by Section 2.01 hereof shall constitute an absolute transfer to 
the Grantee, within the meaning of Section 18-108 of the Funding Law, of any 
right, title and interest Illinois Power may otherwise have had in the 1998 
Transition Property (or any part thereof) created by, under and pursuant to 
the 1998 Funding Order, such transfer is irrevocable and enforceable against 
Illinois Power and its successors, and no interest in or title to the 1998 
Transition Property shall be part of Illinois Power's estate in the event of 
the filing of a bankruptcy petition by or against Illinois Power under any 
bankruptcy law.  No portion of the 1998 Transition Property has been sold, 
transferred, assigned, pledged or otherwise conveyed by Illinois Power to any 
Person other than the Grantee.  Immediately prior to the transactions 
contemplated hereunder, Illinois Power's right, title and interest in and to 
all of its rights to payment under Applicable Rates is free and clear of all 
Liens and rights of any other Person, and no offsets, defenses or 
counterclaims exist or have been asserted with respect thereto. 

     (c)    TRANSFER FILINGS.  The 1998 Transition Property has been validly 
granted and vested in the Grantee pursuant to the 1998 Funding Order and, to 
the extent applicable, this Agreement, and the Grantee owns all right, title 
and interest to the 1998 Transition Property, free and clear of all Liens and 
rights of any other Person (other than Liens created pursuant to the Sale 
Agreement and the Indenture), and all filings to be made by Illinois Power 
(including filings with the ICC under the Funding Law) necessary in any 
jurisdiction to give the Grantee a first priority perfected ownership 
interest in the 1998 Transition Property, free and clear of all Liens, have 
been made.  No further action is required under Illinois law to maintain such 
ownership interest in the 1998 Transition Property.  No further action, other 
than any filings or other steps required to be taken with respect to proceeds 
or on account of events occurring after the date hereof by Sections 9-103, 
9-304, 9-306, 

                                       8
<PAGE>

9-402(7) or 9-403(2)-(3) of the UCC, is required to maintain such first 
priority perfected ownership interest in the Related Assets.

     (d)    STATE PLEDGE.  The State of Illinois has agreed with the Holders, 
pursuant to Section 18-105(b) of the Funding Law, as follows:

            "(b)   The State pledges to and agrees with the holders of any
     transitional funding instruments who may enter into contracts with an
     electric utility, grantee, assignee or issuer pursuant to this Article
     XVIII that the State will not in any way limit, alter, impair or reduce the
     value of intangible transition property created by, or instrument funding
     charges approved by, a transitional funding order so as to impair the terms
     of any contract made by such electric utility, grantee, assignee or issuer
     with such holders or in any way impair the rights and remedies of such
     holders until the pertinent grantee instruments or, if the related
     transitional funding order does not provide for the issuance of grantee
     instruments, the pertinent transitional funding instruments and interest,
     premium and other fees, costs and charges related thereto, as the case may
     be, are fully paid and discharged.  Electric utilities, grantees and
     issuers are authorized to include these pledges and agreements of the State
     in any contract with the holders of transitional funding instruments or
     with any assignees pursuant to this Article XVIII and any assignees are
     similarly authorized to include these pledges and agreements of the State
     in any contract with any issuer, holder or any other assignee.  Nothing in
     this Article XVIII shall preclude the State of Illinois from requiring
     adjustments as may otherwise be allowed by law to the electric utility's
     base rates, transition charges, delivery services charges, or other charges
     for tariffed services, so long as any such adjustment does not directly
     affect or impair any instrument funding charges previously authorized by a
     transitional funding order issued by the [ICC]."

As a result of the foregoing pledge, the State of Illinois may not, except as 
provided in the succeeding sentence, in any way reduce, postpone, impair or 
terminate the 1998 Transition Property in a manner substantially impairing 
the Indenture or the rights and remedies of the Holders (and consequently, 
may not revoke, reduce, postpone or terminate the 1998 Funding Order or the 
rights of the Holders to receive IFC Payments and all other proceeds of the 
1998 Transition Property), until the Notes, together with interest thereon, 
are fully paid and discharged.  Notwithstanding the immediately preceding 
sentence, the State would be allowed to effect a temporary impairment of the 

                                       9
<PAGE>

Holders' rights if it could be shown that a temporary impairment was 
necessary to advance a significant and legitimate public purpose.

     (e)    1998 FUNDING ORDER AND TARIFFS; OTHER APPROVALS.  (i) Illinois 
Power was authorized to file the Application, (ii) Illinois Power filed the 
Application with the ICC on June 24, 1998, in proper form, requesting the 
issuance of a transitional funding order; (iii) the 1998 Funding Order and 
1998 Initial Tariff established, created and granted rights in and to 
intangible transition property in an aggregate amount of $1.634 billion, and 
the 1998 Transition Property and the right to impose and collect IFCs 
constitute current and original property rights vested in the Grantee to the 
fullest extent permitted by law; (iv) the 1998 Funding Order has been duly 
entered by the ICC, is valid and binding, is Final and is in full force and 
effect; (v) the 1998 Initial Tariff is in full force and effect, is valid and 
binding, and is not subject to modification by the ICC except as provided 
under the Funding Law; (vi) as of the issuance of the Notes, the Notes are 
entitled to the protections provided in Section 18-104(c) of the Funding Law 
and, accordingly, the 1998 Funding Order, the 1998 Transition Property and 
the IFCs are not revocable by the ICC; (vii) the ICC may not reduce, 
postpone, impair or terminate the 1998 Transition Property, the 1998 Funding 
Order or the IFCs; (viii) the process by which the 1998 Funding Order was 
adopted and approved and the 1998 Initial Tariff was filed, and the 1998 
Funding Order and the 1998 Initial Tariff themselves, comply with all 
applicable laws, rules and regulations and the ICC may not revoke, amend or 
otherwise change the 1998 Initial Tariff in any manner which would defeat the 
expectations of the Holders to receive IFC Payments on a timely basis; and 
(ix) 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 and grant of the 1998 

                                       10
<PAGE>

Transition Property, except those that have been obtained or made and those 
filings described in Section 3.07.

     (f)    ASSUMPTIONS.  The assumptions used in calculating the IFCs are 
reasonable and made in good faith.

     (g)    CREATION OF 1998 TRANSITION PROPERTY.  Upon the effectiveness of 
the 1998 Initial Tariff: (i) all of the 1998 Transition Property constitutes 
a current property right vested in the Grantee; (ii) the 1998 Transition 
Property includes, without limitation, (A) the right, title and interest in 
the IFCs authorized under the 1998 Funding Order, as adjusted from time to 
time, (B) the right, title and interest in all revenues, collections, claims, 
payments, money or proceeds of or arising from the IFCs set forth in the 1998 
Initial Tariff, and (C) all rights to compel Illinois Power, as Servicer (or 
any successor), to file for and obtain adjustments to the IFCs pursuant to 
the 1998 Funding Order; and (iii) the Grantee is entitled to impose and 
collect the IFCs described in the 1998 Funding Order and the 1998 Initial 
Tariff in an aggregate amount equal to the principal amount of the Notes, all 
interest thereon, all amounts required to be deposited in the Reserve 
Subaccount, the Over-collateralization Subaccount and the Capital Subaccount, 
and all related fees, costs and expenses in respect of the Notes until they 
have been paid in full, subject only to the $1.634 billion limitation set 
forth in the 1998 Funding Order as to the maximum dollar amount of 1998 
Transition Property created thereunder.

     (h)    PROPERTY OF GRANTEE.  To the fullest extent permitted by the 
Funding Law and all other applicable law, the 1998 Transition Property and 
the right to impose and collect IFCs contemplated thereunder constitute 
current property rights of the Grantee and its assigns, including the Note 
Issuer and its assigns (including the Indenture Trustee on behalf of the 
Holders), which property has been 

                                       11
<PAGE>

placed beyond the reach of Illinois Power and its creditors, as in a true 
sale, and which property rights may not be limited, altered, impaired, 
reduced or otherwise terminated by any subsequent actions of Illinois Power 
or any third party and which shall, to the full extent permitted by law, be 
enforceable against Illinois Power, its successors and assigns, and all other 
third parties (including judicial lien creditors) claiming an interest 
therein by or through Illinois Power or its successors and assigns.

     (i)    NATURE OF REPRESENTATIONS AND WARRANTIES.  The representations 
and warranties set forth in this SECTION 3.08, insofar as they involve 
conclusions of law, are made not on the basis that Illinois Power purports to 
be a legal expert or to be rendering legal advice, but rather to reflect the 
parties' good faith understanding of the legal basis on which the parties are 
entering into this Agreement and the other Basic Documents and the basis on 
which the Holders are purchasing the Notes, and to reflect the parties' 
agreement that, if such understanding turns out to be incorrect or 
inaccurate, Illinois Power will be obligated to indemnify the Grantee and its 
permitted assigns, and that the Grantee and its permitted assigns will be 
entitled to enforce any rights and remedies under the documents, on account 
of such inaccuracy to the same extent as if Illinois Power had breached any 
other representations or warranties hereunder.


                                   ARTICLE IV

                           COVENANTS OF ILLINOIS POWER

     SECTION 4.01. CORPORATE EXISTENCE.  So long as any of the Notes are 
outstanding, Illinois Power (a) will keep in full force and effect its 
existence, rights and franchises as a corporation under the laws of the State 
of Illinois (unless it becomes, or any successor to Illinois 

                                       12
<PAGE>

Power hereunder is or becomes, organized under the laws of any other State or 
of the United States of America, in which case Illinois Power will keep in 
full effect its existence, rights and franchises under the laws of such other 
jurisdiction), (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, and any of the other Basic Documents to 
which Illinois Power is a party and each other instrument or agreement 
necessary or appropriate to the proper administration of this Agreement and 
the transactions contemplated hereby and (c) at all times hereafter, neither 
Illinois Power nor any successor will cause or permit the Grantee or the Note 
Issuer to elect to be classified as an association taxable as a corporation 
for federal income tax purposes.

     SECTION 4.02. NO LIENS.  Except for the conveyances hereunder, Illinois 
Power (i) will not sell, pledge, assign or transfer to any other Person, or 
grant, create, incur, assume, suffer to exist or otherwise assert any Lien 
on, any of the 1998 Transition Property or any interest therein, (ii) will 
not at any time assert any Lien against or with respect to any of the 1998 
Transition Property in its capacity as Servicer or otherwise, (iii) will not 
seek to limit, alter, impair, reduce or otherwise terminate the property 
rights of the Grantee or any assignee of the Grantee, and (iv) shall defend 
the right, title and interest of the Grantee or the Note Issuer in, to and 
under the 1998 Transition Property against all claims of third parties 
claiming through or under Illinois Power.

     SECTION 4.03. DELIVERY OF COLLECTIONS.  If Illinois Power receives 
collections in respect of the IFCs or the proceeds thereof, or in replacement 
therefor, including, without limitation, any Allocable IFC Revenue Amounts, 
Illinois Power agrees to hold such payments in trust for the Servicer and to 
pay the Servicer all payments received by Illinois Power in respect thereof 
as soon

                                       13
<PAGE>

as practicable after receipt thereof by Illinois Power, but in no event later 
than two Business Days after such receipt.

     SECTION 4.04. NOTICE OF LIENS.  Illinois Power shall notify the Grantee, 
the Note Issuer and the Indenture Trustee in writing promptly after becoming 
aware of any Lien on any of the 1998 Transition Property other than the 
conveyances hereunder, under the Sale Agreement and under the Indenture.

     SECTION 4.05. COMPLIANCE WITH LAW.  Illinois Power shall comply with its 
organizational or governing documents and all laws, treaties, rules, 
regulations and determinations of any governmental instrumentality applicable 
to it, to the extent that failure to so comply would materially adversely 
affect the Note Issuer's or the Indenture Trustee's interests in the 1998 
Transition Property or under any of the Basic Documents, or Illinois Power's 
performance of its obligations hereunder or under any of the other Basic 
Documents to which it is party.  Without limiting the foregoing, Illinois 
Power shall comply with applicable laws and regulations regarding its use of 
proceeds received hereunder, including all applicable provisions of the 
Funding Law and the 1998 Funding Order.

      SECTION 4.06. COVENANTS RELATED TO THE 1998 TRANSITION PROPERTY AND THE 
NOTES.

     (a)    So long as any of the Notes are outstanding, Illinois Power shall 
indicate in its financial statements that it is not the owner of the 1998 
Transition Property.

     (b)    So long as any of the Notes are outstanding, Illinois Power shall 
not own or purchase any Notes.

     (c)    Illinois Power agrees that upon the creation and grant of the 
1998 Transition Property to the Grantee pursuant to the 1998 Funding Order 
and, to the extent applicable, this Agreement, (i) 

                                       14
<PAGE>

to the fullest extent permitted by law, including applicable ICC Regulations, 
the Grantee shall have all of the rights of the owner of the 1998 Transition 
Property (including all of the rights originally held by Illinois Power, if 
any, with respect to the 1998 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 or third 
party collection agent, including any ARES, in respect of the 1998 Transition 
Property, notwithstanding any objection or direction to the contrary by 
Illinois Power and (ii) any payment by any Customer or third party collection 
agent, including any ARES, to the Grantee (or to the Servicer for the benefit 
of the Grantee) shall discharge such Customer's or third party's obligations 
in respect of the 1998 Transition Property to the extent of such payment, 
notwithstanding any objection or direction to the contrary by Illinois Power.

     (d)    So long as any of the Notes are outstanding, (i) except with 
respect to federal and other applicable taxes, Illinois Power shall not make 
any statement or reference in respect of the 1998 Transition Property that is 
inconsistent with the ownership interest of the Grantee, and (ii) Illinois 
Power shall not take any action in respect of the 1998 Transition Property 
except solely in its capacity as the Servicer under the Servicing Agreement 
or as otherwise contemplated by the Basic Documents.

     (e)    So long as any of the Notes are outstanding, Illinois Power shall 
not, except as required by applicable law, initiate any material changes to 
its policies and procedures pertaining to credit (including requirements for 
deposits from Customers), billing, collections (including procedures for 
disconnection of service for non-payment) and restoration of service after 
disconnection, and shall not initiate any changes in any ICC tariffs relating 
to the foregoing matters 

                                       15
<PAGE>

which are likely to materially and adversely affect Illinois Power's ability 
to make timely recovery of amounts billed to Customers.

     (f)    If Illinois Power determines that the aggregate dollar amount of 
IFCs to be imposed and collected is reasonably likely to exceed the maximum 
dollar amount of Intangible Transition Property authorized by the 1998 
Funding Order and any Subsequent Funding Orders and any Notes remain 
outstanding, Illinois Power shall make a good faith effort to take any and 
all subsequent regulatory action with the ICC reasonably necessary to obtain 
an order permitting the creation of additional Intangible Transition Property 
in an amount sufficient to pay such Notes in full.

     SECTION 4.07. PROTECTION OF TITLE.  Illinois Power shall execute and 
file such filings, including filings with the ICC pursuant to the Funding 
Law, 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 interests of the Grantee or the Note Issuer in the 1998 
Transition Property, including all filings required under the Funding Law 
relating to the grant of the 1998 Transition Property to the Grantee.  
Illinois Power shall deliver (or cause to be delivered) to the Grantee 
file-stamped copies of, or filing receipts for, any document filed as 
provided above, promptly following such filing. Illinois Power shall 
institute any action or proceeding necessary to compel performance by the ICC 
or the State of Illinois of any of their obligations or duties under the 
Funding Law, the 1998 Funding Order, the 1998 Initial Tariff or any 
amendatory tariff filed pursuant to Section 18-104(k) of the Funding Law, and 
Illinois Power 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 protect the Grantee or the Note Issuer from claims, state actions or other 
actions or proceedings of third parties which, if successfully 

                                       16
<PAGE>

pursued, would result in a breach of any representation set forth in Article 
III hereof. The costs of any such actions or proceedings will be payable by 
Illinois Power. Illinois Power designates the Grantee as its agent and 
attorney-in-fact to execute any filings with the ICC or other instruments 
required by the Grantee pursuant to this Section, it being understood that 
the Grantee shall have no obligation to execute any such instruments.

     SECTION 4.08. NONPETITION COVENANTS.  Notwithstanding any prior 
termination of this Agreement or the Indenture, but subject to the ICC's 
right to order the sequestration and payment of revenues arising with respect 
to the 1998 Transition Property notwithstanding any bankruptcy, 
reorganization or other insolvency proceedings with respect to Illinois 
Power, the Grantee or any other grantee or assignee of the 1998 Transition 
Property pursuant to Section 18-107(c)(4) of the Funding Law, Illinois Power 
shall not, prior to the date which is one year and one day after the 
termination of the Indenture, acquiesce, petition or otherwise invoke or 
cause or join with any other Person to invoke the process of any court or 
governmental authority for the purpose of commencing or sustaining a case 
against the Grantee or the Note Issuer under any Federal or state bankruptcy, 
insolvency or similar law or appointing a receiver, liquidator, assignee, 
trustee, custodian, sequestrator or other similar official of or for the 
Grantee or the Note Issuer or any substantial part of the property of the 
Grantee or the Note Issuer, or ordering the winding up or liquidation of the 
affairs of the Grantee or the Note Issuer.

     SECTION 4.09. TAXES.  So long as any of the Notes are outstanding, 
Illinois Power 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 

                                       17
<PAGE>

such taxes, assessments and governmental charges would, after any applicable 
grace periods, notices or other similar requirements, result in a lien on the 
1998 Transition Property; PROVIDED that no such tax need be paid if Illinois 
Power or one of its subsidiaries is contesting the same in good faith by 
appropriate proceedings promptly instituted and diligently conducted and if 
Illinois Power or such subsidiary has established appropriate reserves as 
shall be required in conformity with generally accepted accounting principles.

     SECTION 4.10. CONTRACTS FOR NON-TARIFFED SERVICES.  Neither Illinois 
Power nor any successor thereto shall enter into any contract with any 
Customer obligated (or who would, but for such contract, be obligated) to pay 
IFCs if, as a result thereof, such Customer would not receive tariffed 
services, unless the contract provides that the Customer will pay an amount 
to the Grantee or its assigns or to Illinois Power, as Servicer, as 
applicable, equal to the amount such Customer would pay in IFCs if the 
services provided under such contract were tariffed services, and that the 
Grantee, or if Notes have been issued pursuant to the 1998 Funding Order, the 
Note Issuer, shall be a third-party beneficiary of such provision of such 
contract.  Any revenues received by Illinois Power or such successor from any 
such contract services shall, to the extent of the authorized amount of the 
IFCs included therein (or deemed included therein pursuant to the 1998 
Funding Order and this Section), be deemed to be proceeds of, and included 
in, the 1998 Transition Property.

     SECTION 4.11. PRESERVATION OF RIGHT OF NOTEHOLDERS TO RECEIVE PAYMENT.  
In addition to any obligations of Illinois Power under the Servicing 
Agreement, Illinois Power recognizes and agrees that any impairment of the 
rights of Holders with respect to the collection of IFCs and payments on the 
Notes, arising from a repeal of, modification of or supplement to or 
declaration of invalidity of the Amendatory Act and/or the Funding Law 
occurring after Illinois Power and its 


                                      18

<PAGE>

Affiliates received the proceeds of such Notes, would not be equitable.  
Illinois Power agrees, in consideration of the receipt of such proceeds, to 
take any and all actions reasonably necessary to preserve the rights of 
Holders with respect to payments on the Notes out of the payments represented 
by IFCs or their equivalent, including, but not limited to, (i) making 
appropriate filings with the State of Illinois, the ICC or other regulatory 
bodies to defend, preserve and create on behalf of Holders the right to 
receive payments as provided in the Notes, (ii) defending against or 
instituting and pursuing legal actions and appearing or testifying at 
hearings or similar proceedings, as may be necessary to block or overturn any 
attempts to cause a repeal of, modification of or supplement to or judicial 
invalidation of the Amendatory Act or any Funding Order or the rights of 
holders of Intangible Transition Property by legislative enactment or 
otherwise that would be adverse to the Grantee, the Note Issuer or any 
Holders, and (iii) unless otherwise expressly prohibited by applicable law or 
judicial or regulatory order in effect at such time, continuing to deduct and 
pay over to the Servicer for the benefit of the Note Issuer all IFCs and IFC 
Payments or equivalent revenues received by Illinois Power notwithstanding 
any repeal of, modification of or supplement to or declaration of invalidity 
of the Amendatory Act, the Funding Law and/or the Funding Order.

                                     ARTICLE V

Indenture Trustee and the Delaware Trustee and each of their respective 
officers, directors, employees and agents for, and defend and hold harmless 
each such Person from and against, any and all taxes (i) that may at any 


                                      19

<PAGE>

time be imposed on or asserted against any such Person as a result of the 
grant of the 1998 Transition Property to the Grantee, or (ii) that may be 
imposed on or asserted against any such Person under existing law as of the 
Series Issuance Date as a result of the Grantee's ownership and assignment of 
the 1998 Transition Property, the Note Issuer's issuance and sale of the 
Notes, or the other transactions contemplated herein, including, in each 
case, any sales, gross receipt, general corporation, tangible personal 
property, privilege or license taxes (but excluding any taxes imposed as a 
result of a failure of such Person to properly withhold or remit taxes 
imposed with respect to payments on any Notes).

     (b)    Illinois Power shall indemnify the Grantee, the Note Issuer, the 
Indenture Trustee, the Delaware Trustee and the Holders and each of their 
respective officers, directors, employees and agents for, and defend and hold 
harmless each such Person from and against, any and all amounts of principal 
and interest on the Notes not paid when due in accordance with their terms 
and the amount of any deposits to the Note Issuer required to have been made 
in accordance with the terms of the Basic Documents which are not made when 
so required and any and all liabilities, obligations, claims, actions, suits 
or payments, of any kind whatsoever that may be imposed on or asserted 
against any such Person, together with any reasonable costs and expenses 
incurred by such Person (collectively, "Losses"), as a result of Illinois 
Power's breach of any of its representations, warranties or covenants 
contained in this Agreement.

upon all or any part of the Grantee's property or assets based on existing 
law as of the Closing Date.

     (d)    Indemnification under Sections 5.01(a) through 5.01(c) shall 
survive the termination of this Agreement and shall include reasonable fees 
and expenses of investigation and litigation (including reasonable attorneys' 
fees and expenses).

     SECTION 5.02. MERGER OR CONSOLIDATION OF OR ASSUMPTION OF THE 
OBLIGATIONS OF ILLINOIS POWER.  Any Person (a) into which Illinois Power may 
be merged or consolidated, (b) which may result from any merger or 
consolidation to which Illinois Power shall be a party or (c) which may 
succeed to the properties and assets of Illinois Power substantially as a 
whole, which Person in any of the foregoing cases executes an agreement of 
assumption to perform every obligation of Illinois Power hereunder, shall be 
the successor to Illinois Power under this Agreement without further act on 
the part of any of the parties to this Agreement; PROVIDED, HOWEVER, that (i) 
immediately after giving effect to such transaction, no representation or 
warranty made pursuant to Article III shall have been breached and (if 
Illinois Power 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) Illinois Power shall have delivered to 
the Grantee, the Note Issuer, the Delaware Trustee and the Indenture Trustee 
an Officers' Certificate and an Opinion of Counsel each 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) 
Illinois Power shall have delivered to the Grantee, the Note Issuer and the 
Indenture Trustee an Opinion of Counsel either (x) stating that, in the 
opinion of such counsel, all filings to be made by Illinois Power, including 
filings with the ICC pursuant to the Funding Law, have been executed and 
filed that are necessary to fully preserve and protect the interest of the 
Grantee in the 1998 Transition Property and reciting the details of such 
filings, or (y) 


                                      21

<PAGE>

stating that, in the opinion of such counsel, no such action shall be 
necessary to preserve and protect such interests, (iv) the Rating Agencies 
shall have received prior written notice of such transaction and (v) Illinois 
Power shall have delivered to the Grantee, the Note Issuer, the Delaware 
Trustee and the Indenture Trustee an opinion of independent tax counsel (as 
selected by, and in form and substance reasonably satisfactory to, Illinois

     SECTION 2.01. APPOINTMENT OF SERVICER; ACCEPTANCE OF APPOINTMENT.  Subject
to Section 6.05 and Article 7, the Grantee appoints the Servicer, and the
Servicer accepts such appointment, to perform the Servicer's obligations

<PAGE>

as the servicing agent and custodian for the Grantee with respect to the 
Intangible Transition Property and the Intangible Transition Property 
Records.  The Servicer shall not take any action that is not authorized by

practices, or that shall impair the rights of the Grantee in the Intangible 
Transition Property, in each case unless such action is required by 
applicable law.

                                    ARTICLE III

                                   BILLING SERVICES

     SECTION 3.01. DUTIES OF SERVICER.  The Servicer, as agent for the Grantee,
shall have the following duties:

     (a)    DUTIES OF SERVICER GENERALLY.  The Servicer's duties in general
shall include management, servicing and administration of the Intangible
Transition Property (including maintaining records of the cumulative total of
IFCs and verifying that such amount has not exceeded the dollar amount of
Intangible Transition Property established by the ICC pursuant to a Funding
Order);  on or before the date of issuance of any Series of Notes, filing with
the ICC the filing required by Section 18-107(c)(1) of the Funding Law to
perfect the lien of the Indenture Trustee in the Intangible Transition Property;
making such filings and initiating such proceedings with the ICC as may be
required to ensure that the dollar amount of Intangible Transition Property
authorized by the Funding Orders is adequate for the payment in full of all
principal of and interest on the Notes; obtaining meter reads, calculating
usage, billing, collections and posting of all payments in respect of the
Intangible Transition Property; responding to inquiries by Customers, the ICC or
any federal, local or other state governmental authorities with respect to the

                                      6

<PAGE>

delivering Bills to Customers and ARES, investigating and handling 
delinquencies, processing and depositing collections and making periodic 
remittances; furnishing periodic reports to the Grantee, the Note Issuer, the 
Indenture Trustee and the Rating Agencies; and taking all necessary action in 
connection with Adjustments as set forth herein.  Certain of the duties set 
forth above may be performed by ARES pursuant to ARES Service Agreements.  
The Servicer shall be allowed to perform its duties hereunder either directly 
or by or through agents, attorneys, custodians, nominees or (with prior 
written notice to the Rating Agencies) by delegating all or a portion of its 
duties to any third parties; PROVIDED, however, that, notwithstanding any 
such delegation of duties, the Servicer shall remain liable for the 
performance of all its duties and obligations pursuant to the terms of this 
Agreement and the other Basic Documents and such delegation shall not relieve 
the Servicer of its liability and responsibility with respect to such duties 
or obligations.  The fees and expenses of any such persons to whom the 
Servicer may delegate duties shall be as agreed between the Servicer and such 
third parties from time to time, and, except for such fees and expenses which 
are expressly reimbursable hereunder, such third-party fees and expenses 
shall be payable solely by the Servicer out of its Servicing Fee and neither 
the Grantee nor any assignee thereof shall have any responsibility therefor. 
Anything to the contrary notwithstanding, the duties of the Servicer set 
forth in this Agreement shall be qualified in their entirety by any ICC 
Regulations as in effect at the time such duties are to be performed.  
Without limiting the generality of this Section 3.01(a), in furtherance of 
the foregoing, the Servicer shall also have, and shall comply with, the 
duties and responsibilities relating to data acquisition, usage and bill 
calculation, billing, customer service functions, collections, payment 
processing and remittance set forth in Annex I hereto, including without 
limitation payment of all Allocable IFC Revenue Amounts described therein.

     (b)    REPORTING FUNCTIONS.

                   (i)    MONTHLY SERVICER'S CERTIFICATE.  On or before the
            tenth calendar day of each month (or, if such date is not a Servicer
            Business Day, on the next Servicer Business Day), the Servicer shall
            prepare and deliver to the Grantee, the Note Issuer, the Indenture
            Trustee and the Rating Agencies a written report substantially in
            the form of EXHIBIT A hereto (a "Monthly Servicer's Certificate")
            setting forth certain information relating to IFC Payments received
            by the Servicer during the immediately preceding Billing Period.

                   (ii)   NOTIFICATION OF LAWS AND REGULATIONS.  The Servicer
            shall immediately notify the Grantee, the Note Issuer, the Indenture
            Trustee and the Rating Agencies in writing of any laws or ICC
            Regulations hereafter promulgated that have a material adverse
            effect on the Servicer's ability to perform its duties under this
            Agreement.

                   (iii)  OTHER INFORMATION.  Upon the reasonable request of the
            Grantee, the Note Issuer, the Indenture Trustee or any Rating
            Agency, the Servicer shall provide to the Grantee, the Note Issuer,
            Indenture Trustee or the Rating Agencies, as the case may be, any
            public financial information in respect of the Servicer, or any
            material information regarding the Intangible Transition Property to
            the extent it is reasonably available to the Servicer, as may be
            reasonably necessary and permitted by law, to enable the Grantee,
            the Note Issuer, the Indenture Trustee or the Rating Agencies to
            monitor the Servicer's performance hereunder.  In addition, so long
            as any of the Notes of any Series are outstanding, the Servicer
            shall provide the Grantee, the Note 

                                      8

<PAGE>

            Issuer and the Indenture Trustee, within a reasonable time after 
            written request therefor, any information available to the 
            Servicer or reasonably obtainable by it that is necessary to 
            calculate the IFCs applicable to each class of Customer.

                   (iv)   PREPARATION OF REPORTS TO BE FILED WITH THE SEC.  The
            Servicer shall prepare any reports required to be filed by the
            Grantee or the Note Issuer under the securities laws, including a
            copy of each Quarterly Servicer's Certificate described in Section
            4.01(c)(ii), the annual Certificate of Compliance described in
            Section 3.03, and the Annual Accountant's Report described in
            Section 3.04.

     SECTION 3.02. SERVICING AND MAINTENANCE STANDARDS.  On behalf of the
Grantee, the Servicer shall (i) manage, service, administer and make collections
in respect of the Intangible Transition Property with reasonable care and in
accordance with the Servicing Standard and applicable law, including all
applicable ICC Regulations and guidelines, using the same degree of care and
diligence that the Servicer exercises with respect to similar assets for its own
account and, if applicable, for others; (ii) follow customary standards,
policies and procedures for the industry in performing its duties as Servicer;
(iii) use all reasonable efforts, consistent with its customary servicing
procedures, to enforce, and maintain rights in respect of, the Intangible
Transition Property; (iv) comply with all laws and regulations applicable to and
binding on it relating to the Intangible Transition Property, (v) make all
required submissions and provide all required notifications to the ICC with
respect to any Adjustments, and (vi) maintain facilities sufficient to enable
the Servicer to post IFC Payments to customer accounts within two Servicer
Business Days of receipt of payment by the Servicer, in accordance with Annex I
hereto.  The Servicer shall be responsible for the imposition, collection and
remittance of IFCs in accordance with Annex I hereto, 

                                      9

<PAGE>

the inclusion of IFCs in all Bills, and the deduction of IFCs from tariffed 
charges and all other charges from which the IFCs are to be deducted and 
stated separately, including, without limitation, all charges under any 
contracts with Customers who would, but for such contract, be paying 
Applicable Rates, where such contract provides that the Customer will pay an 
amount each billing period to the Grantee or the Note Issuer, or to the 
Servicer, equal to the amount of IFCs that would have been billed if the 
services provided under such contract were subject to Applicable Rates.  The 
Servicer shall follow such customary and usual practices and procedures as it 
shall deem necessary or advisable in its servicing of all or any portion of 
the Intangible Transition Property, which, in the Servicer's judgment, may 
include the taking of legal action.  Without limiting the foregoing, if the 
Servicer determines at any time that the aggregate dollar amount of IFCs to 
be imposed is reasonably likely to exceed the maximum dollar amount of 
Intangible Transition Property authorized by the 1998 Transitional Funding 
Order and any Subsequent Funding Orders to be imposed and collected and any 
Notes remain outstanding, the Servicer shall make a good faith effort to take 
any and all subsequent regulatory action with the ICC to obtain an order 
expressly authorizing a larger dollar amount of Intangible Transition 
Property in an amount sufficient to pay such Notes in full.

     SECTION 3.03. CERTIFICATE OF COMPLIANCE.  The Servicer shall deliver to 
the Grantee, the Note Issuer, the Indenture Trustee and the Rating Agencies 
on or before September 30 of each year, commencing September 30, 1999 to and 
including the September 30 succeeding the Retirement of the Notes, an 
Officer's Certificate substantially in the form of EXHIBIT B hereto (a 
"Certificate of Compliance"), stating that: (i) a review of the activities of 
the Servicer during the twelve months ended the preceding June 30 (or, in the 
case of the first Certificate of Compliance to be delivered on or before 
September 30, 1999, the period of time from the Closing Date until June 30, 
1999) and 

                                      10

<PAGE>

of its performance under this Agreement has been made under such officer's 
supervision, and (ii) to such officer's knowledge, based on such review, the 
Servicer has fulfilled all of its obligations in all material respects under 
this Agreement throughout such twelve months (or, in the case of the 
Certificate of Compliance to be delivered on or before September 30, 1999, 
the period of time from the Closing Date until June 30, 1999), or, if there 
has been a default in the fulfillment of any such material obligation, 
specifying each such material default known to such officer and the nature 
and status thereof.

     SECTION 3.04. ANNUAL REPORT BY INDEPENDENT PUBLIC ACCOUNTANTS.

     (a)    The Servicer, at its own expense in consideration of the Servicing
Fee paid to it, shall cause a firm of independent certified public accountants
(which may provide other services to the Servicer or Illinois Power) to prepare,
and the Servicer shall deliver to the Grantee, the Note Issuer, the Indenture
Trustee and the Rating Agencies a report addressed to the Servicer (the "Annual
Accountant's Report"), which may be included as part of the Servicer's customary
auditing activities, for the information and use of the Grantee, the Note
Issuer, the Indenture Trustee and the Rating Agencies, on or before September 30
of each year, beginning September 30, 1999 to and including the September 30
succeeding the Retirement of the Notes, to the effect that such firm has
performed certain procedures in connection with the Servicer's compliance with
its obligations under this Agreement during the preceding twelve months ended
June 30 (or, in the case of the first Annual Accountant's Report to be delivered
on or before September 30, 1999, the period of time from the Closing Date until
June 30, 1999), identifying the results of such procedures and including any
exceptions noted.  If such accounting firm requires the Indenture Trustee to
agree or consent to the procedures performed by such firm, the Grantee shall
direct the Note Issuer to direct the Indenture 

                                      11

<PAGE>

Trustee in writing to so agree; it being understood and agreed that the 
Indenture Trustee will deliver such letter of agreement or consent in 
conclusive reliance upon the direction of the Note Issuer, and the Indenture 
Trustee will not make any independent inquiry or investigation as to, and 
shall have no obligation or liability in respect of the sufficiency, validity 
or correctness of such procedures.

     (b)    The Annual Accountant's Report shall also indicate that the
accounting firm providing such report is independent of the Servicer within the
meaning of the Code of Professional Ethics of the American Institute of
Certified Public Accountants.

     SECTION 3.05. OBLIGATIONS.  The Servicer acknowledges and agrees that to
the fullest extent permitted by applicable law, its obligations under this
Agreement shall remain in effect notwithstanding any breach of the State Pledge,
whether or not contested, or subsequent invalidation of the Funding Law or any
Funding Order and/or any tariff or tariffs filed in connection therewith, and
that no such breach of the State Pledge or invalidation shall act to excuse the
Servicer from liability for any failure to perform its covenants hereunder,
including but not limited to its obligation to remit IFCs and equivalent amounts
for the benefit of the Holders, on account of any legal inability stemming from
such breach of the State Pledge or invalidation.


                                     ARTICLE IV
                                           
SERVICES RELATED TO ADJUSTMENTS AND MONITORING OF THIRD-PARTY COLLECTORS

     SECTION 4.01. ADJUSTMENTS.  From time to time, until the Retirement of the
Notes, the Servicer shall identify the need for Adjustments and shall take all
reasonable action to obtain and implement such Adjustments, all in accordance
with the following:

                                      12

<PAGE>

     (a)    EXPECTED AMORTIZATION SCHEDULE.  The initial Expected Amortization
Schedule is attached hereto as SCHEDULE 4.01(a).  In connection with the Note
Issuer's issuance of any additional Series of Notes after the Closing Date, the
Servicer, on or prior to the Series Issuance Date therefor, shall revise the
Expected Amortization Schedule to add the requisite information for each new
Series of Notes and set forth, as of each Payment Date through the scheduled
Retirement of the Notes, the aggregate principal amounts of the Notes of all
Series, including such additional Series, expected to be outstanding on such
Payment Date.  The Servicer shall also, in accordance with the requirements (if
any) set forth in any Series Supplement or Trust Issuance Certificate and
otherwise in a manner reasonably acceptable to the Grantee, revise the Expected
Amortization Schedule to reflect any required prepayments on account of the
receipt of Allocable IFC Revenue Amounts or any other required or permitted
prepayments affecting such schedule.  If the Expected Amortization Schedule is
revised as set forth above, the Servicer shall send a copy of such revised
Expected Amortization Schedule to the Grantee, the Note Issuer, the Indenture
Trustee and the Rating Agencies promptly thereafter.

     (b)    ADJUSTMENTS

                   (i)    ADJUSTMENTS AND FILINGS.  Within the month following
            the end of each Reconciliation Period, the Servicer shall:  (A)
            update the data and assumptions underlying the calculation of the
            IFCs, including revenue from Applicable Rates for each class of
            Customers, projected electricity usage during the next Applicable
            Period for each such class and including interest and estimated
            expenses and fees of the Grantee and the Note Issuer to be paid
            during such period, and the rate of delinquencies and write-offs;
            (B) determine the Required Debt Service and Debt 

                                      13

<PAGE>

            Service Billing Requirement for the next Applicable Period based 
            on such updated data and assumptions; (C) determine the IFCs to 
            be allocated to each class of Customers during the next 
            Applicable Period based on such Debt Service Billing Requirement 
            and the terms of the applicable Funding Orders and the Tariffs 
            filed pursuant thereto (including, without limitation, the terms 
            requiring that if the forecasted revenues from Applicable Rates 
            for any customer class are projected to be less then the IFCs 
            allocated to that class, the deficiency will be ratably allocated 
            to other classes); (D) make all required notice and other filings 
            with the ICC to reflect the revised IFCs, including any 
            Amendatory Tariffs required under Section 18-104(k) of the 
            Funding Law if the resulting IFCs for any class of Customer will 
            exceed an amount per kilowatt-hour greater than the amount per 
            kilowatt-hour authorized for such class of Customer in the 
            applicable Funding Order; and (E) take all reasonable actions and 
            make all reasonable efforts to effect such Adjustment and to 
            enforce the provisions of the Funding Law which limit the ICC's 
            authority to review any such Amendatory Tariff.

                   (ii)   In the case of any Adjustment, the Servicer shall
            implement the revised IFCs, if any, as of the next Adjustment Date.

     (c)    REPORTS.

                   (i)    NOTIFICATION OF AMENDATORY TARIFF FILINGS AND
            ADJUSTMENTS.  Whenever the Servicer files an Amendatory Tariff with
            the ICC or implements revised IFCs with notice to the ICC but
            without filing an Amendatory Tariff or revisions to a Tariff as
            contemplated by any applicable Funding Order, the Servicer 

                                      14

<PAGE>

            shall send a copy of such filing or notice (together with a copy 
            of all notices and documents which, in the Servicer's reasonable 
            judgment, are material to the adjustments effected by such 
            Amendatory Tariff, revised Tariff or notice) to the Grantee, the 
            Note Issuer, the Indenture Trustee and the Rating Agencies 
            concurrently therewith.

                   (ii)   QUARTERLY SERVICER'S CERTIFICATE.  Not later than five
            Servicer Business Days prior to each Payment Date, the Servicer
            shall deliver a written report substantially in the form of EXHIBIT
            D hereto (the "Quarterly Servicer's Certificate") to the Grantee,
            the Note Issuer, the Indenture Trustee and the Rating Agencies.

                   (iii)  REPORTS TO CUSTOMERS.

                          (A)    After each revised IFC has gone into effect
                   pursuant to a Adjustment, the Servicer shall, to the extent
                   and in the manner and time frame required by applicable ICC
                   Regulations, if any, cause to be prepared and delivered to
                   Customers any required notices announcing such revised IFCs.

                          (B)    In addition, at least once each year, the
                   Servicer shall (to the extent that it does not include the
                   notice described below in the Bills regularly sent to
                   Customers) cause to be prepared and delivered to Customers a
                   notice stating, in effect, that the IFCs are owned by the
                   Grantee or any assignee thereof and not Illinois Power.  Such
                   notice shall be included either as an insert to or in the
                   text of the Bills delivered to such Customers or shall be
                   delivered to Customers by electronic means or such other
                   means as the 

                                      15

<PAGE>

                   Servicer or the Applicable ARES may from time to time use 
                   to communicate with their respective customers.

                          (C)    Except to the extent that applicable ICC
                   Regulations make the Applicable ARES responsible for such
                   costs or the Applicable ARES has otherwise agreed to pay such
                   costs, the Servicer shall pay from its own funds all costs of
                   preparation and delivery incurred in connection with clauses
                   (A) and (B) above, including but not limited to printing and
                   postage costs as the same may increase or decrease from time
                   to time.

                   (iv)   ARES REPORTS.  The Servicer shall provide to the
            Rating Agencies, upon request, any publicly available reports filed
            by the Servicer with the ICC (or otherwise made publicly available
            by the Servicer) relating to ARES and any other non-confidential and
            non-proprietary information relating to ARES reasonably requested by
            the Rating Agencies.

     SECTION 4.02. LIMITATION OF LIABILITY.

     (a)    The Grantee and the Servicer expressly agree and acknowledge that:

                   (i)    In connection with any Adjustment, the Servicer is
            acting solely in its capacity as the servicing agent hereunder.

                   (ii)   Neither the Servicer nor the Grantee 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 Amendatory Tariffs
            required by Section 4.01 in a timely and correct manner or other
            breach by the Servicer of its 

                                      16

<PAGE>

            duties under this Agreement), by the ICC in any way related to 
            the Intangible Transition Property or in connection with any 
            Adjustment, the subject of any filings under Section 4.01, any 
            proposed Adjustment, or the approval of any revised IFCs.

                   (iii)  The Servicer shall have no liability whatsoever
            relating to the calculation of any revised IFCs, including as a
            result of any inaccuracy of any of the assumptions made in such
            calculation regarding expected energy usage volume and the rate of
            delinquencies and write-offs, so long as the Servicer has acted in
            good faith and 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 Holders, not
            receiving any payment, amount or return anticipated or expected or
            in respect of any Note generally, except only to the extent that the
            same is caused by the Servicer's gross negligence, willful
            misconduct, bad faith, or reckless disregard of its obligations and
            duties under this Agreement.

     (b)    Notwithstanding the foregoing, this Section 4.02 shall not relieve
the Servicer of liability for any misrepresentation by the Servicer under
Section 6.01 or for any breach by the Servicer of its other obligations under
this Agreement.

     SECTION 4.03. MONITORING OF THIRD-PARTY COLLECTORS.  From time to time,
until the Retirement of the Notes, the Servicer shall, in accordance with the
Servicing Standard, implement such procedures and policies as are necessary to
ensure that the obligations of all Third-Party Collectors to remit IFC Payments
are properly enforced in accordance with the terms and provisions of the
Tariffs.  Such procedures and policies shall include the following:

                                      17

<PAGE>

     (a)    MAINTENANCE OF RECORDS AND INFORMATION.  In addition to any actions
required by ICC Regulations or other applicable law, the Servicer shall:

                   (i)    maintain adequate records for promptly identifying and
            contacting each such Third-Party Collector (including any ARES) and
            for monitoring whether such Third-Party Collector is subject to the
            Seven-Day Remittance Option, the Fifteen-Day Remittance Option, or
            the Alternative Remittance Requirement;

                   (ii)   maintain records of end-user Customers which are
            billed by Third-Party Collectors to permit prompt reversion to
            dual-billing in the event of default by a Third-Party Collector;

                   (iii)  create and periodically update a record of the current
            short-term and long-term unsecured debt ratings, if any, of each
            Third-Party Collector which is responsible for billing IFCs directly
            to end-user Customers and is obligated to remit IFC Payments whether
            or not actually collected from end-user Customers (and, where the
            IFC payment obligations of any Third-Party Collector are guaranteed
            by another entity, the ratings of such other entity);

                   (iv)   create and periodically update, for each Third-Party
            Collector which is responsible for billing IFCs directly to end-user
            Customers and has elected the Fifteen-Day Remittance Option or is
            otherwise obligated to remit IFCs whether or not IFC Payments are
            actually collected from end-user Customers, estimates of one month's
            estimated IFC collections and, in the case of any such Third-Party
            Collector which does not have an unsecured debt rating of at least
            BBB- or the equivalent, 

                                      18

<PAGE>

            maintain a deposit or comparable credit security equal to such one 
            month's estimated IFC Collections as provided in the Tariffs.

     The Servicer shall update the records described in clauses (iii) and (iv)
     above no less frequently than (A) monthly in the case of any such
     Third-Party Collector with expected monthly IFC billings of greater than or
     equal to $5,000,000 and (B) quarterly in each other case. 

     (b)    MONITORING OF PERFORMANCE AND PAYMENT.  In addition to any actions
required by ICC Regulations or other applicable law, the Servicer shall
undertake to do the following:

                   (i)    The Servicer shall require each Third-Party Collector
            which has elected the Fifteen-Day Remittance Option or is otherwise
            obligated to remit IFC Payments whether or not actually collected
            from end-user Customers to pay all undisputed and disputed IFCs
            billed to such Third-Party Collector, in accordance with the
            provisions of the 1998 Initial Tariff and each Subsequent Tariff. 
            The Service shall monitor payment compliance for each Third-Party
            Collector which has elected the Fifteen-Day Remittance Option or is
            otherwise obligated to remit IFC Payments whether or not actually
            collected from end-user Customers.

                   (ii)   The Servicer shall, for each Third-Party Collector
            which is responsible for billing IFCs directly to end-user Customers
            and has elected the Seven-Day Remittance Option or is otherwise
            liable to make IFC Payments only to the extent of collections
            actually received from end-user Customers, compare (x) actual IFC
            Collections from such Third-Party Collector to (y) estimated IFC
            Collections therefrom.  Such comparisons shall be made no less
            frequently than:

                                      19

<PAGE>

                          (A)    Every five Servicer Business Days, in the case
                   of any such Third-Party Collector with expected monthly IFC
                   billings of greater than or equal to $5,000,000;

                          (B)    Monthly in the case of any such Third-Party
                   Collector with expected monthly IFC billings of less than
                   $5,000,000 but greater than or equal to $1,000,000; and

                          (C)    Quarterly in each other case.

            If the discrepancy between actual IFC Collections and estimated IFC
            Collections from any such Third-Party Collector, in the reasonable
            judgment of the Servicer based upon historical experience and any
            other information reasonably available thereto, indicates an actual
            or impending default in such Third-Party Collector's remittance of
            IFC Collections, the Servicer shall promptly notify such Third-Party
            Collector in an attempt to determine the source of discrepancy.  If,
            following such notice, the source of any material discrepancy cannot
            be identified, the Servicer shall, in accordance with ICC
            Regulations and other applicable law and the Servicing Standard,
            take such steps as it reasonably determines are necessary to verify
            whether or not the applicable Third-Party Collector is in default.

                   (iii)  The Servicer shall, consistent with its customary
            billing practices, bill each Third-Party Collector who is obligated
            to pay IFCs on behalf of end-user Customers for all IFCs owed by
            such end-user Customers served thereby in accordance with the
            billing cycle otherwise applicable to such end-user Customers.

                                      20

<PAGE>

     (c)    ENFORCEMENT.  The Servicer shall, in accordance with the terms of
the 1998 Initial Tariff and each Subsequent Tariff, ensure that each Third-Party
Collector remits the undisputed portions of the IFCs or IFC Payments which it is
obligated to remit to the Servicer and remits payment of the disputed amount
under protest (or makes some other suitable and agreeable financial
arrangements) pending a hearing on the matter.  In the event of any default by
any Third-Party Collector, the Servicer shall enforce all rights set forth in,
and take all other steps permitted by, the 1998 Initial Tariff or any Subsequent
Tariff or other ICC Regulations as it determines, in accordance with the
Servicing Standard, are reasonably necessary to ensure the prompt payment of
IFCs by such Third-Party Collector and to preserve the rights of the Holders
with respect thereto, including, where appropriate, taking such steps as it is
permitted to take under applicable law to terminate the right of any Third-Party
Collector to bill and collect IFCs or petitioning the ICC to impose such other
remedies or penalties as may be available under the circumstances.  In the event
any disputed IFCs billed are resolved in favor of a Third-Party Collector and
the Servicer becomes liable for the payment of interest in respect of IFCs paid
under protest or any other penalty, the Servicer agrees that it will pay such
interest or penalty from the Servicing Fee paid to it or its other funds and
shall not deduct such interest or penalty amounts from IFC Collections.

     (d)    CREDIT AND COLLECTION POLICIES.

                   (i)    The Servicer shall, to the full extent permitted under
            the 1998 Funding Order or any Subsequent Funding Order, as
            applicable, impose such terms with respect to credit and collection
            policies applicable to Third-Party Collectors as may be reasonably
            necessary to prevent the then current rating of the Notes from being
            downgraded.  The Servicer shall, in accordance with and to the
            extent permitted by 

                                      21

<PAGE>

            Section 16-118(b) of the Public Utilities Act and the terms of the 
            1998 Funding Order and any subsequent Funding Order, include and 
            impose the above-described terms in all tariffs filed under 
            Section 16-118(b) of the Public Utilities Act which would allow 
            ARES or other utilities to issue single bills to Illinois Power's 
            Customers for services provided by such ARES or other utility 
            and services provided by Illinois Power.  The Servicer shall 
            periodically review the need for modified or additional terms
            based upon, among other things, (i) the relative amount of IFC
            Payments received through Third-Party Collectors relative to the
            Debt Service Billing Requirement, (ii) the historical payment and
            default experience of each ARES and (iii) such other credit and
            collection policies to which the ARES are subject, and will set out
            any such modified or additional terms in a supplemental tariff filed
            with the ICC.

                          THE INTANGIBLE TRANSITION PROPERTY

     SECTION 5.01. CUSTODY OF INTANGIBLE TRANSITION PROPERTY RECORDS.  To assure
uniform quality in servicing the Intangible Transition Property and to reduce
administrative costs, the Grantee revocably appoints the Servicer, and the
Servicer accepts such appointment, to act as the agent of the Grantee, the Note
Issuer and the Indenture Trustee as custodian of any and all documents and
records that the Grantee shall keep on file, in accordance with its customary
procedures, relating to the Intangible Transition Property, including copies of
each Funding Order and all Tariffs relating thereto, and all documents filed
with the ICC in connection with any Adjustment (collectively, the 

                                      22

<PAGE>

"Intangible Transition Property Records"), which are hereby constructively 
delivered to the Note Issuer, as transferee of the Grantee (or, in the case 
of the Subsequent Intangible Transition Property, will as of the applicable 
Subsequent Sale Date be constructively delivered to the Note Issuer, as 
transferee of the Grantee) with respect to all Intangible Transition Property.

     SECTION 5.02. DUTIES OF SERVICER AS CUSTODIAN.

     (a)    SAFEKEEPING.  The Servicer shall hold the Intangible Transition
Property Records on behalf of the Grantee, the Note Issuer and the Indenture
Trustee, and maintain such accurate and complete accounts, records and computer
systems pertaining to the Intangible Transition Property Records as shall enable
the Grantee to comply with this Agreement and the Sale Agreement, and as shall
enable the Note Issuer to comply with the Sale Agreement and the Indenture. 
Except with respect to the commingling of IFC Collections expressly permitted
hereunder, the Servicer shall keep all of the Intangible Transition Property
separate and apart from its other assets, and shall maintain records with
respect to the Intangible Transition Property (including all IFC Collections) in
a manner that facilitates the identification and segregation of such assets from
those of the Servicer.  The Servicer shall, in accordance with the remittance
procedures described in Annex I hereto, maintain records sufficient to permit
the IFC Collections to be accounted for separately from the funds with which
they may be commingled, so that the dollar amounts of IFC Collections commingled
with the Servicer's funds may be properly identified and traced.  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 Grantee, the Note Issuer, the
Indenture Trustee and the Rating Agencies any failure on its part to hold the
Intangible Transition Property Records and 

                                      23

<PAGE>

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 
Grantee, the Note Issuer or the Indenture Trustee of the Intangible 
Transition Property Records.  The Servicer's duties to hold the Intangible 
Transition Property Records on behalf of the Grantee, the Note Issuer and the 
Indenture Trustee set forth in this Section 5.02, to the extent such 
Intangible Transition Property Records have not been previously transferred 
to a successor Servicer pursuant to Article VII, shall terminate three years 
after the earlier of the date on which (i) the Servicer is succeeded by a 
successor Servicer in accordance with Article VII hereof and (ii) no Notes of 
any Series are Outstanding.

     (b)    MAINTENANCE OF AND ACCESS TO RECORDS.   The Servicer shall maintain
the Intangible Transition Property Records at 500 South 27th Street, Decatur,
Illinois 62525, or at such other office as shall be specified to the Grantee,
the Note Issuer and the Indenture Trustee by written notice at least 30 days
prior to any change in location.  The Servicer shall permit the Grantee, the
Note Issuer and the Indenture Trustee or their respective duly authorized
representatives, attorneys or auditors to inspect, audit and make copies of and
abstracts from the Servicer's records regarding the Intangible Transition
Property and the IFCs (including all the Intangible Transition Property
Records), at such times during normal business hours as the Grantee, the Note
Issuer or the Indenture 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 ICC 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).

                                      24

<PAGE>

     (c)    DEFENDING INTANGIBLE TRANSITION PROPERTY AGAINST CLAIMS.  The
Servicer shall institute any action or proceeding necessary to compel
performance by the ICC or the State of Illinois of any of their obligations or
duties under the Funding Law, any Funding Order or any Tariff 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 or
judicial invalidation of, the Amendatory Act, the Funding Law or any Funding
Order or the rights of holders of Intangible Transition Property, or the
promulgation of any ICC Regulations, by legislative action or otherwise, that
would be adverse to the Grantee, the Note Issuer or any Holders.  The Servicer
shall continue to impose IFCs (or equivalent amounts), collect IFCs (or
equivalent amounts), and remit IFCs (or equivalent amounts), in accordance with
this Agreement and to ensure that the IFCs (or equivalent amounts) are
calculated and adjusted in accordance with the provisions hereof and that such
amounts as so adjusted from time to time are deducted from Illinois Power's
Applicable Rates and other charges in accordance with the Basic Documents
continuing until the Retirement of the Notes, in each such case unless otherwise
prohibited by law or by any court or regulatory order in effect at such time. 
The Servicer shall advance its own funds in order to institute any actions or
proceedings described above, PROVIDED, HOWEVER, that the costs of any such
action or proceeding shall be payable from IFC Collections as an Operating
Expense in accordance with the priorities set forth in Section 8.02(d) of the
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 Indenture may be delayed (it being
understood that the Servicer may be required to advance its own funds to satisfy
its obligations hereunder).

                                      25

<PAGE>

     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 Intangible Transition Property Records upon its
receipt of written instructions signed by a Responsible Officer of the Indenture
Trustee.

     SECTION 5.04. CUSTODIAN'S INDEMNIFICATION.  The Servicer as custodian shall
indemnify the Grantee, the Note Issuer, the Delaware Trustee, the Indenture
Trustee and the Holders and each of their respective officers, directors,
employees and agents for, and defend and hold harmless each such Person from and
against, any and all liabilities, obligations, losses, damages, payments and
claims, and reasonable costs or expenses, of any kind whatsoever (collectively,
"Losses") that may be imposed on, incurred by or asserted against any such
Person as the result of any improper act or omission in any way relating to the
maintenance and custody by the Servicer, as custodian, of the Intangible
Transition Property Records; PROVIDED, HOWEVER, that the Servicer shall not be
liable for any portion of any such amount resulting from the willful misconduct,
bad faith or gross negligence of the Grantee, the Note Issuer, the Delaware
Trustee, the Indenture Trustee or any Holders.

     Indemnification under this Section shall survive resignation or removal of
the Indenture Trustee or the Delaware Trustee and shall include reasonable
out-of-pocket fees and expenses of investigation and litigation.

     SECTION 5.05. 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.  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 

                                      26

<PAGE>

terminated under Section 7.01, the appointment of such Servicer as custodian 
shall be terminated by the Indenture Trustee or by the Holders of Notes 
evidencing not less than twenty-five percent (25%) of the Outstanding Amount 
of the Notes of all Series in the same manner as the Indenture Trustee or 
such Holders may terminate the rights and obligations of the Servicer under 
Section 7.01.

     SECTION 5.06. GENERAL INDEMNIFICATION OF INDENTURE TRUSTEE AND DELAWARE
TRUSTEE.  The Servicer agrees to indemnify and hold harmless the Indenture
Trustee and the Delaware Trustee and their respective directors, officers,
employees and agents from and against any and all Losses incurred by or asserted
against any such Person as a result of or in connection with the transactions
contemplated by this Agreement or any other Basic Document, other than any Loss
incurred by reason or result of the gross negligence or willful misconduct of
the Indenture Trustee or the Delaware Trustee; PROVIDED, HOWEVER, that the
foregoing indemnity is extended to the Indenture Trustee and the Delaware
Trustee solely in their respective capacities as trustees and not for the
benefit of the Holders or any other Person.  The obligations of the Servicer set
forth herein shall survive the termination of this Agreement or the earlier
resignation or removal of the Indenture Trustee under the Indenture or the
Delaware Trustee under the Trust Agreement.


                                     ARTICLE VI

                                     THE SERVICER

Transition Property pursuant to a Subsequent Sale Agreement, and as of such
other dates as expressly provided in this Section 6.01, on which the 

                                      27

<PAGE>

Grantee is deemed to have relied in entering into this Agreement.  The

the Sale Agreement and the pledge thereof to the Indenture Trustee pursuant 
to the Indenture.

     (a)    ORGANIZATION AND GOOD STANDING.  The Servicer is duly organized and

     (b)    DUE QUALIFICATION.  The Servicer is duly qualified to do business as

and approvals in, all jurisdictions in which the ownership or lease of property
or the conduct of its business (including the servicing of the Intangible
Transition Property as required by this Agreement) shall require such
qualifications, licenses or approvals (except where the failure to so qualify
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 Intangible Transition Property).

     (c)    POWER AND AUTHORITY.  The Servicer has the requisite 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

<PAGE>

     (d)    BINDING OBLIGATION.  This Agreement constitutes a legal, valid and
binding obligation of the Servicer enforceable in accordance with its terms,
subject to applicable insolvency, reorganization, moratorium, fraudulent
transfer and other similar laws relating to or affecting creditors' rights
generally from time to time in effect and to general principles of equity
(including, without limitation, 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,

incorporation or bylaws of the Servicer, or any indenture, agreement or other
instrument to which the Servicer is a party or by which it shall be bound; (ii)
result in the creation or imposition of any Lien upon any of its properties

Servicer or its properties.

     (f)    NO PROCEEDINGS. Except as set forth on Schedule 6.01(f), there are
no proceedings or investigations pending or, to the Servicer's knowledge,
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 Grantee
or, to the Servicer's knowledge, any other Person: (i) asserting the invalidity
of this Agreement, or any of the other Basic Documents or the Notes, (ii)
seeking to prevent the issuance of the Notes or the consummation of any of the

the Servicer and which could reasonably be expected to adversely affect the 
Federal or state income tax attributes of the Notes.

administrative agency or other governmental instrumentality is required in
connection with the Servicer's execution and delivery of this Agreement, the
Servicer's performance of the transactions contemplated hereby or the Servicer's
fulfillment 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 IV hereof.

     (h)    CALCULATIONS AND ASSUMPTIONS.  The calculations and assumptions used
by the Servicer in calculating the IFCs in effect from time to time are
reasonable and made in good faith.

     (i)    REPORTS AND CERTIFICATES.  Each report and certificate delivered in
connection with a Tariff will constitute a representation and warranty by the
Servicer that each such report or certificate, as the case may be, is true and
correct; PROVIDED, HOWEVER, that to the extent any such report or certificate is
based in part upon or contains assumptions, forecasts or other predictions of
future events, the representation and warranty of the Servicer with respect
thereto will be limited to the representation and warranty that such
assumptions, forecasts or other predictions of future events are reasonable
based upon historical performance and other pertinent information.

its reckless disregard of its obligations and duties under this Agreement, or
(ii) the Servicer's breach of any of its representations or warranties in this
Agreement.

     (c)    For purposes of Section 6.02(b), in the event of the termination of

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.

     (d)    Indemnification under Section 6.02 shall survive any repeal of,
modification of, supplement to, or judicial invalidation of, the Funding Law or

Trustee or the Delaware Trustee or the termination of this Agreement and shall
include reasonable out-of-pocket fees and expenses of investigation and
litigation (including reasonable attorneys' fees and expenses incurred by any
indemnified party).

     (e)    Except to the extent expressly provided in this Agreement or the

releases and discharges the Grantee, the Note Issuer, the Delaware Trustee 
and the Indenture Trustee and each of their respective officers, directors 
and agents (collectively, the "Released Parties") from any and all actions, 
claims and demands whatsoever, whenever arising, which the Servicer, in its 
capacity as Servicer or otherwise, shall or may have against any such Person 
relating to the Intangible Transition Property or the Servicer's activities 
with respect thereto other than any actions, claims and demands arising out 
of the willful misconduct, bad faith or gross negligence of the Released 
Parties.

     SECTION 6.03. 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, or, with respect to its obligations as
Servicer, 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 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
Grantee, the Note Issuer, the Indenture Trustee and the Rating Agencies an
Officers' Certificate and an Opinion of Counsel each stating that such

Servicer shall have delivered to the Grantee, the Note Issuer, the Indenture
Trustee and the Rating Agencies an Opinion 

                                      32

<PAGE>

of Counsel either (A) stating that, in the opinion of such counsel, all 
filings to be made by the Servicer, including filings with the ICC pursuant 
to the Funding Law, have been executed and filed that are necessary to 
preserve and protect fully the interests of the Grantee in the Intangible 
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 Servicer shall have given 
the Rating Agencies prior written notice of such merger or consolidation.  
Notwithstanding anything herein to the contrary, the execution of the 
foregoing agreement of assumption and compliance with clauses (i), (ii) and 
(iii) above shall be conditions to the consummation of the transactions 
referred to in clauses (a), (b) or (c) above.

     SECTION 6.04. LIMITATION ON LIABILITY OF SERVICER AND OTHERS.  Neither the
Servicer nor any of the directors or officers or employees or agents of the
Servicer shall be liable to the Grantee, the Note Issuer, the Indenture Trustee,
the Delaware Trustee, the Holders or any other Person, except as provided under
this Agreement, 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 such person against
any liability that would otherwise be imposed by reason of willful misconduct,
bad faith or gross negligence in the performance of the Servicer's duties or by
reason of reckless disregard of the Servicer's obligations and duties.  The
Servicer and any director or officer or employee or agent of the Servicer may
rely in good faith on the advice of counsel reasonably acceptable to the
Indenture Trustee or on any document of any kind, PRIMA FACIE properly executed
and submitted by any Person, respecting any matters arising under this
Agreement.

hereby imposed on it as Servicer 

                                      33

<PAGE>

under this Agreement unless either (a) the Servicer determines that the 
performance of its duties under this Agreement shall no longer be permissible 
under applicable law (disregarding any breach of the State Pledge that is 
being contested or subsequent invalidation of the Funding Law, any Funding 
Order and/or any Tariff or Tariffs filed in connection therewith), or (b) the 
Rating Agency Condition shall have been satisfied and, in either such case, 
to the extent required under any Funding Order, the ICC shall have approved 
such resignation.  Notice of any such determination permitting Illinois 
Power's resignation shall be given to the Grantee, the Note Issuer, the 
Indenture 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 shall be 
evidenced by an Opinion of Counsel to such effect delivered to the Grantee, 
the Note Issuer and the Indenture Trustee concurrently with or promptly after 
such notice.  No such resignation shall become effective until a successor 
Servicer shall have assumed Illinois Power's responsibilities and obligations 
in accordance with Section 7.02.  Illinois Power shall not terminate the 
Administration Agreement prior to the repayment in full of all Notes.

     SECTION 6.06. SERVICING COMPENSATION.  

     (a)    In consideration for its services hereunder, until the Retirement of
the Notes, the Servicer shall receive a fee (the "Servicing Fee") quarterly on
each Payment Date in an amount (i) equal to $540,000 for so long as IFCs are
billed concurrently with charges or otherwise billed to Customers or (ii) not to
exceed $3,240,000 if IFCs are not billed concurrently with charges otherwise
billed to Customers but, instead, are billed separately to Customers.  The
Servicer shall also be entitled to retain as additional compensation (i) any
interest earnings on IFC Payments received by the Servicer and invested by the
Servicer pursuant to Section 6(d) of Annex I hereto during each 

                                      34

<PAGE>

Collection Period prior to remittance to the Collection Account and (ii) all 
late payment charges, if any, collected from Customers or ARES.  So long as 
the Servicer is billing Customers for charges for electric service or any 
Applicable Rates, the Servicer will bill IFCs to such Customers concurrently 
with such other charges and such Applicable Rates.

     (b)    The Servicer shall receive, in accordance with Section 8.02 of the
Indenture, the Servicing Fee set forth in Section 6.06(a) above on each Payment
Date in accordance with the priorities set forth in Section 8.02(d) of the
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)    Except as provided in Section 5.02(c), the Servicer shall be
required to pay from its own account all expenses incurred by it 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 and
any expenses incurred in connection with reports to Holders) out of the
compensation retained by or paid to it pursuant to this Section 6.06, and shall
not be entitled to any extra payment or reimbursement therefor.

     SECTION 6.07. COMPLIANCE WITH APPLICABLE LAW.  The Servicer covenants and
agrees, in servicing the Intangible Transition Property, to comply with all laws
applicable to, and binding upon, the Servicer and relating to such Intangible
Transition Property the noncompliance with which would have a material adverse
effect on the value of the Intangible Transition Property; PROVIDED, HOWEVER,
that the foregoing is not intended to, and shall not, impose any liability on
the Servicer for 

                                      35

<PAGE>

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
INTANGIBLE TRANSITION PROPERTY.  The Servicer shall provide to the Grantee, the
Note Issuer, the Indenture Trustee and the Holders access to the Intangible
Transition Property Records in such cases where the Grantee, the Note Issuer,
the Indenture Trustee and the Holders 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 offices of
the Servicer.  Nothing in this Section shall affect the Servicer's obligation to
observe any applicable law (including any ICC 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, unless such person is Illinova Corporation or a
wholly-owned subsidiary thereof, the Rating Agency Condition shall have been
satisfied in connection therewith; PROVIDED FURTHER that the Servicer shall
remain obligated and be liable to the Grantee, the Note Issuer, the Indenture
Trustee and the Holders for the servicing and administering of the Intangible
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 Intangible Transition Property; and
PROVIDED FURTHER, HOWEVER, that nothing herein (including, without limitation,
the Rating Agency Condition) shall 


                                      36


<PAGE>

preclude the execution by the Servicer of an ARES Service Agreement with any 
ARES pursuant to applicable ICC Regulations. The fees and expenses of such 
Person shall be as agreed between the Servicer and such Person from time to 
time and none of the Grantee, the Note Issuer, the Indenture Trustee, the 
Holders or any other Person shall have any responsibility therefor or right 
or claim thereto.  No such appointment shall constitute a Servicer 
resignation under Section 6.05.

     SECTION 6.10. NO SERVICER ADVANCES.  The Servicer shall not make any
advances of interest or principal on the Notes.

     SECTION 6.11. REMITTANCES.

     (a)    Subject to clause (b) below, on each Servicer Business Day, the
Servicer shall remit to the General Subaccount of the Collection Account the
total IFC Payments collected by the Servicer from or on behalf of Customers on
the second preceding Servicer Business Days (the "Daily Remittance"), which
Daily Remittance shall be determined according to the procedures set forth in
Annex I.  Prior to or accompanying each remittance to the General Subaccount of
the Collection Account pursuant to this Section, the Servicer shall provide
written notice to the Indenture Trustee of each such remittance (including the
exact dollar amount to be remitted).

     (b)    Notwithstanding the foregoing clause (a), unless a Servicer Default
has occurred and is continuing or if the Rating Agency Condition is not
satisfied, during any period in which the Servicer maintains a short-term rating
of A-1 or better by Standard & Poor's, P-1 or better by Moody's, (if rated by
Duff & Phelps) D-1 or better by Duff & Phelps and (if rated by Fitch IBCA) F-1
or better by Fitch IBCA, the Servicer shall no longer be required to make Daily
Remittances, and, in lieu thereof, the Servicer shall, on each Monthly
Remittance Date, cause to be made a wire 

                                       37

<PAGE>

transfer of immediately available funds equal to the Aggregate Remittance 
Amount for the applicable Billing Period to the General Subaccount of the 
Collection Account.

     (c)    The Servicer agrees and acknowledges that it holds all IFC Payments
collected by it for the benefit of the Grantee or the Note Issuer, as
applicable, and that all such amounts shall be remitted by the Servicer in
accordance with this Section without any surcharge, fee, offset, charge or other
deduction except for late fees permitted by Section 6.06.  The Servicer shall
not make any claim to reduce its obligation to remit all IFC Payments collected
by it in accordance with this Agreement except for late fees permitted by
Section 6.06.

     (d)    Unless otherwise instructed in writing by the Note Issuer, the
Servicer, on behalf of the Note Issuer, shall be responsible for selecting
Eligible Investments in which the funds in the Collection Account shall be
invested pursuant to Section 8.03 of the Indenture.

     SECTION 6.12. COMPLIANCE WITH SERVICING STANDARD; CHANGES IN ICC TARIFFS. 
The Servicer shall, with respect to its duties hereunder, comply at all times
with the Servicing Standard, and, so long as any of the Notes are outstanding,
shall not initiate any material changes with respect to its policies and
procedures pertaining to credit (including requirements for deposits from
Customers), billing, collections (including procedures for disconnection of
service for non-payment) and restoration of service after disconnection, and
shall not, except as required by applicable law, initiate any changes in any ICC
tariffs relating to the foregoing which are reasonably likely to materially and
adversely affect the Servicer's ability to make timely recovery of amounts
billed to Customers.  Notwithstanding the foregoing, the Servicer may, in its
own discretion, waive any late payment charge or any other fee or charge
relating to delinquent payments, if any, and may waive, vary or modify any terms
of payment of any amounts payable by a Customer, in each case, if such 

                                       38

<PAGE>

waiver or action (a) would be in accordance with the Servicer's customary 
practices or those of any successor Servicer with respect to comparable 
assets that it services for itself, (b) would not materially adversely affect 
the Holders and (c) would comply with applicable law.  In addition, the 
Servicer may write off any amounts that it deems uncollectible in accordance 
with its customary practices.

                                    ARTICLE VII

                                       DEFAULT

     SECTION 7.01. SERVICER DEFAULT.  If any one of the following events (a
"Servicer Default") shall occur and be continuing:

     (a)    any failure by the Servicer to deposit in the Collection Account on
behalf of the Grantee any required remittance that shall continue unremedied for
a period of three Business Days after written notice of such failure is received
by the Servicer from the Grantee, the Note Issuer or the Indenture Trustee or
after discovery of such failure by a Responsible Officer of the Servicer; or

     (b)    any failure on the part of the Servicer or Illinois Power, as the
case may be, duly to observe or to perform in any material respect any other
covenant or agreement of the Servicer or Illinois Power (as the case may be) set
forth in this Agreement (including Section 4.01) or any other Basic Document to
which it is a party, which failure shall (i) materially and adversely affect the
rights of the Holders and (ii) continue unremedied for a period of 30 days after
the date on which written notice of such failure, requiring the same to be
remedied, shall have been given (A) to the Servicer or Illinois Power (as the
case may be) by the Grantee or the Note Issuer or (B) to the Servicer or
Illinois Power (as the case may be) by the Indenture Trustee or by the Holders
of Notes 

                                       39

<PAGE>

evidencing not less than twenty-five percent (25%) of the Outstanding Amount 
of the Notes of all Series; or

     (c)    any representation or warranty made by the Servicer in this
Agreement shall prove to have been incorrect when made, which has a material
adverse effect on the Grantee, the Note Issuer or the Holders and which material
adverse effect continues unremedied for a period of 60 days after the date on
which written notice thereof requiring the same to be remedied, shall have been
delivered to the Servicer by the Grantee, the Note Issuer or the Indenture
Trustee; or

     (d)    an Insolvency Event occurs with respect to the Servicer or Illinois
Power; then, and in each and every case, so long as the Servicer Default shall
not have been remedied, either the Indenture Trustee, or the Holders of Notes
evidencing not less than twenty-five percent (25%) of the Outstanding Amount of
the Notes of all Series, by notice (a "Termination Notice") then given in
writing to the Servicer and the Rating Agencies (and to the Indenture Trustee if
given by the Holders) 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 ICC for sequestration
and payment of revenues arising with respect to the Intangible Transition
Property: (1) the Holders and the Indenture Trustee as beneficiaries of the lien
provided under Section 18-107(c) of the Funding Law; (2) the Grantee or its
assignees; (3) the Note Issuer; or (4) pledges or transferees of the Intangible
Transition Property.  On or after the receipt by the Servicer of a Termination
Notice, all authority and power of the Servicer under this Agreement, whether
with respect to the Notes, the Intangible Transition Property, the IFCs 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, 

                                       40

<PAGE>

the Indenture Trustee is 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 Intangible Transition 
Property Records and related documents, or otherwise.  The predecessor 
Servicer shall cooperate with the successor Servicer, the Grantee, the Note 
Issuer and the Indenture 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 
(i) 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 Intangible Transition Property or the IFCs, and (ii) any and all 
Intangible Transition Property Records.  All reasonable out-of-pocket costs 
and expenses (including attorneys' fees and expenses) incurred in connection 
with transferring the Intangible 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 Servicing Fee, 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 a
successor Servicer with the Grantee's prior 

                                       41

<PAGE>

written consent thereto (which consent shall not be unreasonably withheld), 
and the successor Servicer shall accept its appointment by a written 
assumption in form acceptable to the Grantee and the Note Issuer and provide 
prompt notice of such assumption to the Indenture Trustee and the Rating 
Agencies.  If within 30 days after the delivery of the Termination Notice, 
the Note Issuer shall not have obtained such a new Servicer, the Indenture 
Trustee may petition the ICC 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 and ICC 
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 Grantee 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 of all Series may,
on behalf of all Holders, 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 deposits to the Collection Account in accordance with
this Agreement, which waiver shall require the consent of all Holders.  Upon any
such waiver of a past default, such default shall cease to exist, and any
Servicer Default arising 

                                       42

<PAGE>

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 Grantee, the Note Issuer, the Indenture Trustee and the Rating Agencies,
promptly after having obtained knowledge thereof, but in no event later than
five Business Days thereafter, written notice in an Officer's 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.

     (a)    This Agreement may be amended in writing by the Servicer and the
Grantee with five Business Days' prior written notice given to the Rating
Agencies and the prior written consent of the Indenture Trustee, but without the
consent of any of the Holders or Holders, 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 Holders;
PROVIDED, HOWEVER, that such action shall not, as evidenced by an Officer's
Certificate delivered to the Grantee, the Note Issuer, the Delaware Trustee and
the Indenture Trustee, adversely affect in any material respect the interests of
any Holder.

     This Agreement may also be amended in writing from time to time by the
Servicer and the Grantee with prior written notice given to the Rating Agencies
and the prior written consent of the 

                                       43

<PAGE>

Indenture Trustee and the prior written consent of the Holders of Notes 
evidencing not less than a majority of the Outstanding Amount of the Notes of 
all Series, for the purpose of adding any provisions to or changing in any 
manner or eliminating any of the provisions of this Agreement or of modifying 
in any manner the rights of the Holders; PROVIDED, HOWEVER, that no such 
amendment shall (a) increase or reduce in any manner the amount of, or 
accelerate or delay the timing of, IFC Collections, or the timing of 
adjustments to IFCs, or (b) reduce the aforesaid percentage of the 
Outstanding Amount of the Notes, the Holders of which are required to consent 
to any such amendment, without the consent of the Holders of all the 
outstanding Notes.

     Promptly after the execution of any such amendment and the requisite
consents, the Grantee shall furnish written notification of the substance of
such amendment to the Note Issuer, the Indenture Trustee and each of the Rating
Agencies.

     It shall not be necessary for the consent of Holders 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 its consent to any amendment to this Agreement, the Indenture
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 Indenture Trustee may, but shall not be obligated to, enter into
any such amendment which affects the Indenture Trustee's own rights, duties,
indemnities or immunities under this Agreement or otherwise.

     (b)    Notwithstanding Section 8.01(a) or anything to the contrary in this
Agreement, the Servicer and the Grantee may amend Annex I to this Agreement in
writing with prior written notice given to the Indenture Trustee and the Rating
Agencies, but without the consent of the Indenture 

                                       44

<PAGE>

Trustee, any Rating Agency or any Holder, solely to address changes to the 
Servicer's method of calculating IFC Payments received as a result of changes 
to the Servicer's current computerized customer information system; PROVIDED 
that any such amendment shall not have a material adverse effect on the 
Holders.

     SECTION 8.02. MAINTENANCE OF RECORDS.  The Servicer shall maintain accounts
and records as to the Intangible Transition Property accurately and in
accordance with its standard accounting procedures and in sufficient detail to
permit reconciliation between IFC Payments received by the Servicer and IFC
Collections from time to time deposited in the Collection Account.

     SECTION 8.03. NOTICES.  All demands, notices and communications upon or to
the Servicer, the Grantee, the Note Issuer, the Indenture Trustee or the Rating
Agencies under this Agreement shall be in writing and personally delivered, sent

Federal or state bankruptcy, insolvency or similar law or appointing a

expressly waived by the parties who are signatories to this Agreement and by 
any Person claiming by, through or under such parties and (d) under no

payment of any indebtedness or expenses of the Note Issuer or the Holders, 
respectively, or be personally liable for the breach or failure of any 
obligation, representation, warranty or covenant made or undertaken by the 
Delaware Trustee or the Indenture Trustee, respectively, under this 
Agreement; PROVIDED, HOWEVER, that this provision shall not protect First

                                       ANNEX I
                                         TO
                                SERVICING AGREEMENT

     The Servicer agrees to comply with the following servicing procedures:

     SECTION 1.    DEFINITIONS.

     (a)    Capitalized terms used herein and not otherwise defined shall have
the meanings set forth in the Servicing Agreement.

     (b)    Whenever used in this Annex I, the following words and phrases shall
have the following meanings:

            "APPLICABLE MDMA" means with respect to each Customer, the meter
data management agent providing meter reading services for that Customer's
account.

            "BILLED IFCS" means the amounts of IFCs billed to Customers, whether
billed directly to such Customers by the Servicer or indirectly through an
Applicable ARES pursuant to Consolidated ARES Billing.

            "CONSOLIDATED ARES BILLING" means the billing option available to
Customers served by an ARES pursuant to which such ARES will be responsible for
billing and collecting all charges to Customers electing such billing option,
including the IFCs, all in accordance with applicable ICC Regulations.

            "IFC CUSTOMER CLASS" means the separate classes of Customers for IFC
billing purposes set forth in any Tariffs.

            "LEVELIZED PAYMENT PLAN" means a billing plan offered by the
Servicer which, if elected by a Customer, provides for monthly charges to such
Customer on its Bills which are calculated as 1/12th of the amount billed (or
which would have been billed to the Customer based on actual usage) during the
preceding twelve months, with the Customer being charged or credited (as the
case may be), at the time billing to the Customer under the Levelized Payment
Plan terminates, for the difference between the amounts billed to the Customer
pursuant to the Levelized Payment Plan and the amount that would have been
billed to the Customer based on actual usage.

            "SERVICER POLICIES AND PRACTICES" means, with respect to the
Servicer's duties under this Annex I, the policies and practices of the Servicer
applicable to such duties that the Servicer follows with respect to comparable
assets that it services for itself.

     SECTION 2.    DATA ACQUISITION.

     (a)    INSTALLATION AND MAINTENANCE OF METERS.  Except to the extent that
an ARES is responsible for such services pursuant to an ARES Service Agreement,
the Servicer shall cause to 

                                       I-1

<PAGE>

be installed, replaced and maintained meters in such places and in such 
condition as will enable the Servicer to obtain usage measurements for each 
Customer at least once every Billing Period.

     (b)    METER READING.  At least once each Billing Period, the Servicer
shall obtain usage measurements from the Applicable MDMA for each Customer;
PROVIDED, HOWEVER, that the Servicer may determine any Customer's usage on the
basis of estimates in accordance with applicable ICC Regulations.

     (c)    COST OF METERING.  Neither the Grantee nor the Note Issuer shall be
obligated to pay any costs associated with the metering duties set forth in this
Section 2, including, but not limited to, the costs of installing, replacing and
maintaining meters, nor shall the Grantee or the Note Issuer be entitled to any
credit against the Servicing Fee for any cost savings realized by the Servicer
or any ARES as a result of new metering and/or billing technologies.

     SECTION 3.    USAGE AND BILL CALCULATION.

     The Servicer shall obtain a calculation of each Customer's usage (which may
be based on data obtained from such Customer's meter read or on usage estimates
determined in accordance with applicable ICC Regulations) at least once each
Billing Period and shall determine therefrom each Customer's individual IFCs to
be included on such Customer's Bill; PROVIDED, HOWEVER, that in the case of
Customers served by an ARES under the Consolidated ARES Billing option, the
Applicable ARES, rather than the Servicer, may determine such Customer's
individual IFCs to be included on such Customer's Bills based on billing factors
provided by the Servicer, and, in such case, the Servicer shall deliver to the
Applicable ARES such billing factors as are necessary for the Applicable ARES to
calculate such Customers' respective IFCs as such charges may change from time
to time pursuant to Adjustments.

     SECTION 4.    BILLING.

     The Servicer shall implement the IFCs as of the Closing Date and shall
thereafter bill each Customer or the Applicable ARES for the respective
Customer's outstanding current and past due IFCs accruing through December 31,
2008, or such longer period during which the Notes may remain outstanding, all
in accordance with the following:

     (a)    FREQUENCY OF BILLS; BILLING PRACTICES.  In accordance with the
Servicer's then-existing Servicer Policies and Practices for its own charges, as
such Servicer Policies and Practices may be modified from time to time, the
Servicer shall generate and issue a Bill to each Customer, or, in the case of a
Customer who has elected Consolidated ARES Billing, to the Applicable ARES, for
such Customer's respective IFCs once every applicable Billing Period, at the
same time, with the same frequency and on the same Bill as that containing the
Servicer's own charges to such Customer or ARES, as the case may be.  In the
event that the Servicer makes any material modification to these practices, it
shall notify the Grantee, the Note Issuer, the Indenture Trustee, and the Rating
Agencies prior to the effectiveness of any such modification; PROVIDED, HOWEVER,
that the Servicer may not make any modification that will materially adversely
affect the Holders.

                                       I-2

<PAGE>

     (b)    FORMAT.

            (i)    Each Bill to a Customer shall contain the charge
corresponding to the respective IFCs owed by such Customer for the applicable
Billing Period.  The IFCs and related credits shall each appear as a separate
line-item on each Bill.

            (ii)   In the case of each Customer that has elected Consolidated
ARES Billing, the Servicer shall deliver to the Applicable ARES itemized charges
for such Customer setting forth such Customer's IFCs and related credits, each
as a separate line-item.

            (iii)  The Servicer shall conform to such requirements in respect of
the format, structure and text of Bills delivered to Customers and ARES as
applicable ICC Regulations shall from time to time prescribe.  To the extent
that Bill format, structure and text are not prescribed by the Public Utilities
Act or by applicable ICC Regulations, the Servicer shall, subject to clauses (i)
and (ii) above, determine the format, structure and text of all Bills in
accordance with its reasonable business judgment, its Servicer Policies and
Practices with respect to its own charges and prevailing industry standards.

     (c)    ALLOCATIONS OF IFCS.  IFCs and related credits shall be deducted
from all amounts constituting Applicable Rates and from all charges to Customers
from which IFCs must be deducted pursuant to the Funding Orders, whether or not
such Applicable Rates or charges are computed on a cents per kilowatt hours
basis, according to some other usage-based calculation, on a fixed basis, or in
any other fashion or by any combination of the foregoing.  If the IFC calculated
for any Customer for any Billing Period exceeds the amount of its otherwise
Applicable Rates, then the Bill to such Customer shall reflect an IFC and
related credit each equal to the total amount of such Applicable Rates.

     (d)    DELIVERY.  The Servicer shall deliver all Bills to Customers (i) by
United States Mail in such class or classes as are consistent with the Servicer
Policies and Practices followed by the Servicer with respect to its own charges
to its customers or (ii) by any other means, whether electronic or otherwise,
that the Servicer may from time to time use to present its own charges to its
customers.  In the case of Customers that have elected Consolidated ARES
Billing, the Servicer shall deliver all Bills to the Applicable ARES by such
means as are prescribed by applicable ICC Regulations, or if not prescribed by
applicable ICC Regulations, by such means as are mutually agreed upon by the
Servicer and the Applicable ARES and are consistent with ICC Regulations.  The
Servicer or an ARES, as applicable, shall pay from its own funds all costs of
issuance and delivery of all Bills, including but not limited to printing and
postage costs as the same may increase or decrease from time to time.

     SECTION 5.    CUSTOMER SERVICE FUNCTIONS.

     The Servicer shall handle all Customer inquiries and other Customer service
matters according to the same procedures it uses to service Customers with
respect to its own charges.

                                       I-3

     SECTION 6.    COLLECTIONS; PAYMENT PROCESSING; REMITTANCE.

     (a)    COLLECTION EFFORTS, POLICIES, PROCEDURES.

            (i)    The Servicer shall use reasonable efforts to collect all
Billed IFCs from Customers and Third-Party Collectors (including ARES) as and
when the same become due and shall follow such collection procedures as it
follows with respect to comparable assets that it services for itself or others,
including with respect to the following:

            (A)    The Servicer shall prepare and deliver overdue notices to
                   Customers and ARES in accordance with applicable ICC
                   Regulations and Servicer Policies and Practices.

            (B)    The Servicer shall apply late payment charges to outstanding
                   Customer and ARES balances in accordance with applicable ICC
                   Regulations.  All late payment charges and interest collected
                   shall be payable to and retained by the Servicer as a
                   component of its compensation under the Agreement, and the
                   Note Issuer shall have no right to share in the same.

            (C)    The Servicer shall deliver verbal and written final notices
                   of delinquency and possible disconnection in accordance with
                   applicable ICC Regulations and Servicer Policies and
                   Practices.

            (D)    The Servicer shall adhere to and carry out disconnection
                   policies in accordance with the Public Utilities Act and
                   applicable ICC Regulations and Servicer Policies and
                   Practices.

            (E)    The Servicer may employ the assistance of collection agents
                   to collect any past-due IFCs in accordance with the
                   applicable ICC regulations and Servicer Policies and
                   Practices and the Tariffs.

            (F)    The Servicer shall apply Customer and ARES deposits to the
                   payment of delinquent accounts in accordance with applicable
                   ICC Regulations and Servicer Policies and Practices and
                   according to the priorities set forth in Section 6(b)(ii),
                   (iii) and (iv) of this Annex I.

            (ii)   The Servicer shall not waive any late payment charge or any
other fee or charge relating to delinquent payments, if any, or waive, vary or
modify any terms of payment of any amounts payable by a Customer, in each case
unless such waiver or action: (A) would be in accordance with the Servicer's
customary practices or those of any successor Servicer with respect to
comparable assets that it services for itself and for others; (B) would not
materially adversely affect the rights of the Holders; and (C) would comply with
applicable law; PROVIDED, HOWEVER, that notwithstanding anything in the
Agreement or this Annex I to the contrary, the Servicer is authorized 

                                       I-4

<PAGE>

to write off any Billed IFCs, in accordance with its Servicer Policies and 
Practices, that have remained outstanding for 180 days or more.

            (iii)  The Servicer shall accept payment from Customers and
Third-Party Collectors in respect of Billed IFCs in such forms and methods and
at such times and places as it accepts for payment of its own charges.  The
Servicer shall accept payment from ARES in respect of Billed IFCs in such forms
and methods and at such times and places as the Servicer and each ARES shall
mutually agree in accordance with applicable ICC Regulations, and the Servicer
shall give prompt written notice to the Rating Agencies of any such agreements.

     (b)    PAYMENT PROCESSING; ALLOCATION; PRIORITY OF PAYMENTS.

            (i)    The Servicer shall post all payments received to Customer
accounts as promptly as practicable, and, in any event, substantially all
payments shall be posted no later than (A) one Servicer Business Day after
receipt by the Servicer if payment is made directly to the Servicer by a
Customer, (B) two Servicer Business Days after receipt by a Thirty-Party
Collector (other than an ARES or another electric utility) acting as agent for
the Servicer, or (C) two Servicer Business Days after receipt by the Servicer
from an ARES or another electric utility.

            (ii)   Subject to clause (iii) below, the Servicer shall apply
payments received to each Customer's or Applicable ARES' account in proportion
to the charges contained on the outstanding Bill to such Customer or Applicable
ARES.

            (iii)  Any amount collected by the Servicer that represent partial
payments of the total Bill to a Customer or ARES shall be allocated to amounts
owed to the Note Issuer and Illinois Power, regardless of age, pro rata in
proportion to their respective percentages of the total amount of their combined
outstanding charges on such Bill.

            (iv)   The Servicer shall hold all over-payments for the benefit of
the Note Issuer and Illinois Power and shall apply such funds to future Bill
charges in accordance with clauses (ii) and (iii) above as such charges become
due.

            (v)    For Customers on a Levelized Payment Plan, the Servicer shall
treat IFC Payments received from such Customers as if such Customers had been
billed for their respective IFCs in the absence of the Levelized Payment Plan;
partial payment of a Levelized Payment Plan payment shall be allocated according
to clause (iii) above and overpayment of a Levelized Payment  Plan payment shall
be allocated according to clause (iv) above.

     (c)    ACCOUNTS; RECORDS.

            The Servicer shall maintain accounts and records as to the 
Intangible Transition Property accurately and in accordance with its standard 
accounting procedures and in sufficient detail (i) to permit reconciliation 
between payments or recoveries with respect to the Intangible Transition 
Property and the amounts from time to time remitted to the Collection Account 
in respect  

                                       I-5

<PAGE>

of the Intangible Transition Property and (ii) to permit the IFC Collections 
held by the Servicer to be accounted for separately from the funds with which 
they may be commingled, so that the dollar amounts of IFC Collections 
commingled with the Servicer's funds may be properly identified and traced.

     (d)    INVESTMENT OF IFC PAYMENTS RECEIVED.

            Prior to remittance on the applicable Monthly Remittance Date (or,
to the extent remittances are required more frequently under the Indenture,
prior to each Daily Remittance) the Servicer may invest IFC Payments received at
its own risk and for its own benefit, and such investments and, so long as the
Servicer complies with its obligations under the immediately preceding section
(c), such funds shall not be required to be segregated from the other investment
and funds of the Servicer.

     (e)    CALCULATION OF COLLECTIONS

            (i)    For purposes of Section 6.11 of the Agreement and Section
6(g) of this Annex, the IFC Payments collected by the Servicer on any Servicer
Business Day shall be the sum of (A) the IFC Payments posted to Customer
accounts of the Servicer on the second preceding Servicer Business Day in
accordance with Section 6(b) of this Annex and (B) any Allocable IFC Revenue
Amounts, determined in accordance with Section 6(f) of this Annex, received by
the Servicer on such second preceding Servicer Business Day.

            (ii)   All calculations of collections shall be made in good faith.
