provided in Section 2 of this Article III, directors shall be elected by a
plurality of the votes cast at the Annual Meeting of Stockholders and each
director so elected shall hold office until the next Annual Meeting of

death, resignation, disqualification, removal, or other causes shall be filled
by either (i) the affirmative vote of the holders of a majority of the voting
power of the then-outstanding shares of voting stock of this Corporation
entitled to vote generally in the election of directors, voting together as a
single class; or (ii) by the affirmative vote of a majority of the remaining
directors then in office, even though less than a quorum. Newly created
directorships resulting from any increase in the number of
directors shall, unless the Board of Directors determines by resolution that
any such newly-created directorship shall be filled by the stockholders, be
filled only by the affirmative vote of the directors then in office, even
though less than a quorum of the Board of Directors. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of directors in which the new directorship was
created or the vacancy occurred and until such director’s successor shall have
been elected and qualified.

 

Section 3. Duties and
Powers. The business and affairs of the Corporation shall be
managed by or under the direction of the Board of Directors which may exercise
all such powers of the Corporation and do all such lawful acts and things as

required to be exercised or done by the stockholders.

 

Section 4. Meetings. The Board of
Directors may hold meetings, both regular and special, either within or without
the State of Delaware. Regular meetings of the Board of Directors may be held
without notice at such time and at such place as may from time to time be

 

10

 

determined by the Board
of Directors. Special meetings of the Board of Directors may be called by the
Chairman, if there be one, or the President. Notice thereof stating the place,
date and hour of the meeting shall be given to each director either by mail not
less than forty-eight (48) hours before the date of the meeting, by telephone
or telegram on twenty-four (24) hours’ notice, or on such shorter notice as the
person or persons calling such meeting may deem necessary or appropriate in the
circumstances.

 

Section 5. Quorum. Except as
otherwise required by law or the Certificate of Incorporation, at all meetings
of the Board of Directors, a majority of the entire Board of Directors shall
constitute a quorum for the transaction of business and the act of a majority
of the directors present at any meeting at which there is a quorum shall be the
act of the Board of Directors. If a quorum shall not be present at any meeting
of the Board of Directors, the directors present thereat may adjourn the
meeting from time to time, without notice other than announcement at the
meeting of the time and place of the adjourned meeting, until a quorum shall be
present.

 

Section 6. Actions by Written Consent. Unless
otherwise provided in the Certificate of Incorporation, or these Bylaws, any
action required or permitted to be taken at any meeting of the Board of
Directors or of any committee thereof may be taken without a meeting, if all
the members of the Board of Directors or committee, as the case may be, consent
thereto in writing, and the writing or writings are filed with the minutes of
proceedings of the Board of Directors or committee.

 

Section 7. Meetings by Means of Conference Telephone. Unless
otherwise provided in the Certificate of Incorporation, members of the Board of
Directors of the Corporation, or any committee thereof, may participate in a
meeting of the Board of Directors or such committee by means of a conference
telephone or similar communications equipment by

 

11

 

means of which all
persons participating in the meeting can hear each other, and participation in
a meeting pursuant to this Section 7 shall constitute presence in person at
such meeting.

 

Section 8.
Committees. The Board of Directors may designate one or more
commit­tees, each committee to consist of one or more of the directors of the
Corporation. The Board of Directors may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of any such committee. In the absence or disqualification
of a member of a committee, and in the absence of a designation by the Board of
Directors of an alternate member to replace the absent or disqualified member,
the member or members thereof present at any meeting and not
disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any absent or disqualified member. Any
committee, to the extent permitted by law and provided in the resolution
establishing such committee, shall have and may exercise all the powers and
authority of the Board of Directors in the management of the business and
affairs of the Corporation, and may authorize the seal of the Corporation to be
affixed to all papers which may require it. Each committee shall keep regular
minutes and report to the Board of Directors when required.

directors may be paid their expenses, if any, of attendance at each meeting of
the Board of Directors and may be paid a fixed sum for attendance at each
meeting of the Board of Directors or a stated salary as director, payable in
cash or securities. No such payment shall preclude any director from serving
the Corporation in any other capacity and receiving compensation therefore.
Members of special or standing committees may be allowed like compensation for
attending committee meetings.

Section 10. Interested Directors. No contract
or transaction between the Corporation and one or more of its directors or
officers, or between the Corporation and any other corporation, partnership,
association, or other organization in which one or more of its directors or
officers are directors or officers or have a financial interest, shall be void
or voidable solely for this reason, or solely because the director or officer
is present at or participates in the meeting of the Board of Directors or
committee thereof which authorizes the contract or transaction, or solely
because the director or officer’s vote is counted for such purpose if (i) the
material facts as to the director or officer’s relationship or interest and as to the contract
or transaction are disclosed or are known to the Board of Directors or the
committee, and the Board of Directors or committee in good faith authorizes the
contract or transaction by the affirmative votes of a majority of the
disinterested directors, even though the disinterested directors be less than a
quorum; or (ii) the material facts as to the director or officer’s relationship
or interest and as to the contract or transaction are disclosed or are known to
the stockholders entitled to vote thereon, and the contract or transaction is
specifically approved in good faith by vote of the stockholders; or (iii) the
contract or transaction is fair as to the Corporation as of the time it is
authorized, approved or ratified by the Board of Directors, a committee thereof
or the stockholders. Common or interested directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee which authorizes the contract or transaction.

resignation, retirement or removal from office, of all books, papers, vouchers,
money and other property of whatever kind in the Assistant Treasurer’s
possession or under the Assistant Treasurer’s control belonging to the
Corporation.

 

Section 11. Other
Officers. Such other officers as the Board of Directors may
choose shall perform such duties and have such powers as from time to time may
be assigned to them by the Board of Directors. The Board of Directors may delegate
to any officer of the Corporation the power to choose such other officers and
to prescribe their respective duties and powers.

STOCK

 

Section 1. Issuance of
Shares Without Certificates.  The Corporation may issue some or all of the
shares of any or all of its classes or series without certificates.  Within a reasonable time after issuance or
transfer of uncertificated stock, the Corporation shall send or shall cause to
be sent to the registered owner thereof: (i) a written statement that the
Corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative participating, optional or other
special rights of each class of stock or series thereof and the qualifications,

case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such

be issued by the Corporation with the same effect as if such person were such
officer, transfer agent or registrar at the date of issue.

 

Section 3. Lost
Certificates. The Board of Directors may
direct a new certificate to be issued in place of any certificate theretofore
issued by the Corporation alleged to have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the person claiming the certificate
of stock to be lost, stolen or destroyed. When authorizing such issue of a new
certificate, the Board of Directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed certificate, or the owner’s legal representative, to advertise the
same in such manner as the Board of Directors shall require

 

19

 

and/or
to give the Corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the Corporation with respect to the
certificate alleged to have been lost, stolen or destroyed or the issuance of
such new certificate.

 

Section 4. Transfers. Stock of the Corporation shall be transferable in the manner
prescribed by law and in these Bylaws. Transfers of stock shall be made on the
books of the Corporation only by the person named in the certificate or by such
person’s attorney lawfully consti­tuted in writing and upon the surrender of
the certificate therefore, which shall be cancelled before a new certificate
shall be issued. No transfer of stock shall be valid as against the Corporation
for any purpose until it shall have been entered in the stock records of the
Corporation by an entry showing from and to whom transferred.

 

Section 5. Record Date.

 

(a)       In order that the Corporation may determine the stockholders entitled

thereof, the board of directors may fix a record date, which record date shall
not precede the date upon which the resolution fixing the record date is
adopted by the Board of Directors, and which record date shall not be more than
sixty nor less than ten days before the date of such meeting. If no record date
is fixed by the Board of Directors, the record date for determining
stockholders entitled to notice of or to vote at a meeting of stockholders
shall be at the close of business on the day next preceding the day on which
notice is given, or, if notice is waived, at the close of business on the day
next preceding the day on which the meeting is held. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; providing, however,
that the Board of Directors may fix a new record date for the adjourned
meeting.

 

20

 

(b)      In order that the Corporation may
determine the stockholders entitled to receive payment of any dividend or other
distribution or allotment of any rights or the stockholders entitled to
exercise any rights in respect of any change, conversion or exchange of stock,
or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record
date shall not precede the date upon which the resolution fixing the record
date is adopted, and which record date shall be not more than sixty days prior
to such action. If no record date is fixed, the record date for determining
stockholders for any such purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating thereto.

a person registered on its books as the owner of shares to receive dividends,
and to vote as such owner, and to hold liable for calls and assessments a
person registered on its books as the owner of shares, and shall not be bound
to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person, whether or not it shall have express or
other notice thereof, except as otherwise required by law.

ARTICLE VIII

 

INDEMNIFICATION

 

Section
I. Power to Indemnify in Actions, Suits or Proceedings other than Those by or
in the Right of the Corporation. Subject to Section 3 of this Article VIII, the Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the Corporation) by reason of the fact that such person is or was
a director or officer of the Corporation, or is or was a director or officer of
the Corporation serving at the request of the Corporation as a director or
officer, employee or agent of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorneys’ fees), judgments, fines

 

23

 

and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding if such person acted in good
faith and in a manner such person reasonably believed to be in the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person’s conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which such person reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any criminal
action or proceeding, had reasonable cause to believe that such person’s
conduct was unlawful.

 

Section
2. Power to Indemnify in Actions, Suits or Proceedings by or in the Right of
the Corporation. Subject to
Section 3 of this Article VIII, the Corporation shall indemnify any person who
was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that such person is or
was a director or officer of the Corporation, or is or was a director or
officer of the Corporation serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise against expenses
(including attorneys’ fees) actually and reasonably incurred by such person in
connection with the defense or settlement of such action or suit if such person
acted in good faith and in a manner such person reasonably believed to be in
the best interests of the Corporation; provided, that no indemnifica­tion
shall be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the Corporation unless and only to the
extent that the Court of Chancery or the court in which such action or suit was
brought shall

 

24

 

determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

 

Section 3. Authorization of
Indemnification. Any
indemnification under this Article VIII (unless ordered by a court) shall be
made by the Corporation only as authorized in the specific case upon a
determination that indemnification of the director or officer is proper in the
circumstances because such person has met the applicable standard of conduct
set forth in Section 1 or Section 2 of this Article VIII, as the case may be.
Such determination shall be made, with respect to a person who is a director or
officer at the time of such determination, (i) by a majority vote of the
directors who are not parties to such action, suit or proceeding, even though
less than a quorum, or (ii) by a committee of such directors designated by a
majority vote of such directors, even though less than a quorum, or (iii) if
there are no such directors, or if such directors so direct, by independent
legal counsel in a written opinion or (iv) by the stockholders. Such
determination shall be made, with respect to former directors and officers, by
any person or persons having the authority to act on the matter on behalf of
the Corporation. To the extent, however, that a present or former director or
officer of the Corpora­tion has been successful on the merits or otherwise in
defense of any action, suit or proceeding described above, or in defense of any
claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys’ fees) actually and reasonably incurred by such
person in connection therewith, without the necessity of authorization in the
specific case.

 

Section 4. Good Faith Defined. For purposes of any determination under Section 3 of this Article
VIII, a person shall be deemed to have acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
Corporation, or, with respect to any criminal action or proceeding, to have had
no reasonable cause to

 

25

 

believe
such person’s conduct was unlawful, if such person’s action is based on the
records or books of account of the Corporation or another enterprise, or on
information supplied to such person by the officers of the Corporation or
another enterprise in the course of their duties, or on the advice of legal
counsel for the Corporation or another enterprise or on information or records
given or reports made to the Corporation or another enterprise by an
independent certified public accountant or by an appraiser or other expert
selected with reasonable care by the Corporation or another enterprise. The
provisions of this Section 4 shall not be deemed to be exclusive or to limit in
any way the circumstances in which a person may be deemed to have met the
applicable standard of conduct set forth in Section 1 or 2 of this Article
VIII, as the case may be.

 

Section
5. Indemnification by a Court. Notwithstanding any contrary determination in the specific case under
Section 3 of this Article VIII, and notwithstanding the absence of any determi­nation
thereunder, any director or officer may apply to the Court of Chancery in the
State of Delaware for indemnification to the extent otherwise permissible under
Sections 1 and 2 of this Article VIII. The basis of such indemnification by a
court shall be a determination by such court that indemnification of the
director or officer is proper in the circumstances because such person has met
the applicable standards of conduct set forth in Section 1 or 2 of this Article
VIII, as the case may be. Neither a contrary determination in the specific case
under Section 3 of this Article VIII nor the absence of any determination
thereunder shall be a defense to such application or create a presumption that
the director or officer seeking indemnification has not met any applicable
standard of conduct. Notice of any application for indemnification pursuant to
this Section 5 shall be given to the Corporation promptly upon the filing of
such application. If successful, in whole or in part, the director or officer
seeking indemnification shall also be entitled to be paid the expense of
prosecuting such application.

 

26

 

Section 6. Expenses Payable
in Advance. Expenses incurred by a
director or officer in defending any civil, criminal, administrative or
investigative action, suit or proceeding shall be paid by the Corporation in
advance of the final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such director or officer to repay
such amount if it shall ultimately be determined that such person is not
entitled to be indemnified by the Corporation as authorized in this Article
VIII.

 

Section 7. Nonexclusivity of
Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by or
granted pursuant to this Article VIII shall not be deemed exclusive of any
other rights to which those seeking indemnification or advancement of expenses
may be entitled under the Certificate of Incorporation, any Bylaw, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action
in such person’s official capacity and as to action in another capacity while
holding such office, it being the policy of the Corporation that
indemnification of the persons specified in Sections 1 and 2 of this Article
VIII shall be made to the fullest extent permitted by law. The provisions of
this Article VIII shall not be deemed to preclude the indemnification of any
person who is not specified in Section 1 or 2 of this Article VIII but whom the
Corporation has the power or obligation to indemnify under the provisions of
the DGCL.

 

Section 8. Insurance. The Corporation may purchase and maintain insurance on behalf of any
person who is or was a director or officer of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise against any liability asserted against such
person and incurred by such person in any such capacity, or arising out of such
person’s status as such, whether or not the Corporation would have the power or
the obligation to indemnify such person against such liability under the
provisions of this Article

 

27

 

VIII.

 

Section 9. Certain Definitions. For purposes of this Article VIII, references to “the Corporation”
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors or officers, so that
any person who is or was a director or officer of such constituent corporation,
or is or was a director or officer of such constituent corporation serving at
the request of such constituent corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, shall stand in the same position
under the provisions of this Article VIII with respect to the resulting or
surviving corporation as such person would have with respect to such
constituent corporation if its separate existence had continued. For purposes
of this Article VIII, references to “fines” shall include any excise taxes
assessed on a person with respect to an employee benefit plan; and references
to “serving at the request of the Corporation” shall include any service as a
director, officer, employee or agent of the Corporation which imposes duties
on, or involves services by, such director or officer with respect to an
employee benefit plan, its participants or beneficiaries; and a person who
acted in good faith and in a manner such person reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner “not opposed to the best interests of
the Corporation” as referred to in this Article VIII.

 

Section 10. Survival of Indemnification and Advancement of Expenses. The indemnifi­cation and advancement of
expenses provided by, or granted pursuant to, this Article VIII shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director or officer and shall inure to the benefit of the heirs,
executors and

 

28

 

administrators
of such a person.

 

Section 11. Limitation on Indemnification. Notwithstanding anything contained in this
Article VIII to the contrary, except for proceedings to enforce rights to
indemnification (which shall be governed by Section 5 hereof), the Corporation
shall not be obligated to indemnify any director or officer in connection with
a proceeding (or part thereof) initiated by such person unless such proceeding
(or part thereof) was authorized or consented to by the Board of Directors of
the Corporation.

 

Section 12. Indemnification of Employees and Agents. The Corporation may, to the extent
authorized from time to time by the Board of Directors, provide rights to
indemnification and to the advancement of expenses to employees and agents of
the Corporation similar to those conferred in this Article VIII to directors
and officers of the Corporation.

 

ARTICLE IX

 

AMENDMENTS

 

Section 1. Amendments. These Bylaws may be altered, amended or repealed, in whole or in part,
or new Bylaws may be adopted by the stockholders or by the Board of Directors,
provided, however, that notice of such alteration, amendment, repeal or
adoption of new Bylaws be contained in the notice of the meeting of
stockholders or Board of Directors, as the case may be. All amendments must be
approved by either sixty-six and two-thirds percent (66 2/3%) of the
outstanding capital stock entitled to vote thereon or by a majority of the
entire Board of Directors then in office.

 

Section 2. Entire Board of Directors. As used in this Article IX and in these
Bylaws generally, the term “entire Board of Directors” means the total number
of directors which the Corpora­tion would have if there were no vacancies.

Company Order

 

November 20, 2007

 

The Bank of New York
Trust Company, N.A.

Two North LaSalle Street,
Suite 1020

Chicago, IL  60602

 

Ladies and Gentlemen:

 

Application is hereby
made to The Bank of New York Trust Company, N.A., a national banking
association, as trustee (the “Trustee”), under the Indenture dated as of June
1, 2006 (the “Indenture”), between Illinois Power Company, an Illinois
corporation (the “Company”), and the Trustee for the authentication and
delivery of $250,000,000 aggregate principal amount of the Company’s 6.125%
Senior Secured Notes due 2017 (the “Notes”), pursuant to the provisions of
Article II of the Indenture. Additional Notes without limitation as to amount,
and without the consent of the holders of the then Outstanding Notes, may also
be authenticated and delivered in the manner provided in Section 2.05 of the
Indenture. All capitalized terms not defined herein that are defined in the
Indenture shall have the same meaning as used in the Indenture.

 

The Notes will be
initially issued pursuant to Section 4(2) of the Securities Act of 1933, as
amended (the “Securities Act”), in the form of Global Notes registered in the
name of Cede & Co. (as nominee for The Depository Trust Company (“DTC”),
New York, New York, which will act as the Depositary for the Global Notes). Pursuant
to Section 2.05(c) of the Indenture, the Notes will have the terms set forth in
the form of Global Note attached hereto as Exhibit A and in the form of
definitive Note attached hereto as Exhibit B (which terms are incorporated by
reference in this Company Order). The Global Notes shall bear the depository
legend in substantially the form set forth in Exhibit A attached hereto. The
Notes will be issued only in denominations of $1,000 and in integral multiples
of $1,000 in excess thereof.

 

Initially, beneficial
interests in the Notes offered and sold to qualified institutional buyers (as
defined in Rule 144A under the Securities Act) (“QIBs”) in reliance upon Rule
144A under the Securities Act will be represented by one or more separate
Global Notes (each, a “Rule 144A Global Certificate”) registered in the name of
Cede & Co., as registered owner and as nominee for DTC and shall include
the non-registration and registration rights legends set forth in Exhibit A
attached hereto. Initially beneficial interests in the Notes offered and sold
to purchasers pursuant to Regulation S under the Securities Act will be
evidenced by one or more separate temporary Global Notes (each, a “Temporary
Regulation S Global Certificate”) and will be registered in the name of Cede
& Co., as registered owner and as nominee for DTC for the accounts of The
Euroclear System (“Euroclear”) or Clearstream Banking, Luxembourg, société
anonyme (“Clearstream”) and shall include the Regulation S and
registration rights legends set forth in Exhibit A attached hereto. Notes
offered and sold to institutional “accredited investors” (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act) who are not QIBs and who
are not purchasers pursuant to Regulation S under the Securities Act will be in
definitive form in the form attached hereto as Exhibit B and shall include
the non-registration and registration 

 

 

rights legends set forth therein. The Trustee and the Company will have
no responsibility or liability for any aspect of transfers of beneficial
interests in the Notes (which transfers will be conducted pursuant to the
customary procedures of DTC), any records of DTC of beneficial interests or any
transactions between DTC and its participants or between any such participants
and any other beneficial owners or for monitoring, supervising or reviewing of
any thereof.

 

Transfers of beneficial
interests in the Rule 144A Global Certificate will be subject to the
restrictions on transfer contained in the non-registration legend set forth in
Exhibit A hereto. Prior to the expiration of the period of
40 consecutive days beginning on and including the later of (x) the day on
which the offering of the Notes commences and (y) the original issue date of
the Notes (the “Distribution Compliance Period”), transfers of beneficial
interests in the Temporary Regulation S Global Certificate will be subject
to the restrictions on transfer contained in the Regulation S legend set
forth in Exhibit A hereto. At any time after the expiration of the
Distribution Compliance Period, upon receipt by the Trustee and the Company of
a certificate from Euroclear or Clearstream certifying that it has received
certification of non-U.S. beneficial ownership of a Temporary Regulation S
Global Certificate (or portion thereof) with respect to any Notes to be
exchanged, one or more separate permanent Global Notes (each, a “Permanent
Regulation S Global Certificate” and, together with each Temporary Regulation S
Global Certificate, each, a “Regulation S Global Certificate”) shall be duly
executed by the Company and authenticated by the Trustee as provided in the
Indenture, shall be registered in the name of Cede & Co., as registered
owner and as nominee for DTC, and shall include the registration rights legend
set forth in Exhibit A hereto and shall be deposited with the Trustee, as
custodian for DTC. The Trustee, as custodian for DTC, shall reflect by
endorsement thereon a decrease in the principal amount of the Temporary Regulation
S Global Certificate in an amount equal to the principal amount of such
Temporary Regulation S Global Certificate exchanged. Prior to the expiration of
the Distribution Compliance Period, beneficial interests in any Temporary
Regulation S Global Certificate may only be held through Euroclear or
Clearstream. After the expiration of the Distribution Compliance Period,
transfers of beneficial interests in the Permanent Regulation S Global
Certificate will not be subject to any restrictions.

 

In connection with any
transfer of Notes, the Trustee and the Company shall be under no duty to
inquire into, may conclusively presume the correctness of, and shall be fully
protected in relying upon the certificates and other information (set forth in
the form of definitive Note attached hereto as Exhibit B, for use in connection
with the transfer of the Notes in definitive form, or set forth in Exhibit A-1
attached hereto, for use in connection with the transfer of beneficial
interests between a Rule 144A Global Certificate and a Regulation S Global
Certificate or to a Note in definitive form, or otherwise) received from the
Holders and any transferees of any Notes regarding the validity, legality and
due authorization of any such transfer, the eligibility of the transferee to
receive such Note and any other facts and circumstances related to such
transfer. Transfers of beneficial interests between a Rule 144A Global
Certificate and a Regulation S Global Certificate, and other transfers relating
to beneficial interests in the Notes in global form, shall be reflected by
endorsements of the Trustee, as custodian for DTC, on the schedule attached to
such certificate.

 

The Company has entered
into a Registration Rights Agreement dated as of November 20, 2007 (the “Registration
Rights Agreement”) with the initial purchasers of the Notes pursuant 

 

2

 

to which the Notes that are issued and sold without registration (the “Private
Notes”) under the Securities Act may be exchanged for Notes that will be
registered under the Securities Act and that will otherwise have substantially
the same terms as the Private Notes (the “Exchange Notes”), except that such
Exchange Notes will be issued in the form of Global Note attached hereto as
Exhibit A and will bear all customary legends (except for the non-registration,
Regulation S and registration rights legends) or, in lieu of such exchange, the
Company has agreed to file a shelf registration statement for the resale of the
Notes (in which case any Notes so resold will be issued in the form of Global
Note attached hereto as Exhibit A and bear all customary legends (except
for the non-registration, Regulation S and registration rights legends)). The
Private Notes will be exchanged for Exchange Notes only pursuant to an
effective registration statement under the Securities Act and otherwise in
accordance with the Registration Rights Agreement and the Indenture. The
Private Notes and the Exchange Notes will constitute a single series of notes
under the Indenture. Exchange Notes shall be authenticated and delivered by the
Trustee at one time or from time to time upon the receipt by the Trustee of a
Company Order in principal amounts equal to the principal amounts of the
Private Notes surrendered in exchange therefor. In addition, upon the receipt
of such Company Order, the Trustee will take such actions as to effectuate the
exchange of any Private Notes for Exchange Notes in accordance with the
Registration Rights Agreement and the Indenture.

 

In connection with this
Company Order, there are delivered to you herewith the following:

 

1.               Certified copies of

promises to pay to CEDE & CO. or registered assigns, the principal amount
specified above on the Maturity Date set forth above, and to pay interest
thereon from and including the Original Issue Date specified above or from and

provided for in the immediately preceding sentence. For purposes of this Note,
the term “interest” shall be deemed to include interest provided for in the

such interest, which shall be May 1 or November 1, as the case may be, next
preceding such Interest Payment Date; provided, that the first Interest Payment
Date for any part of this Note, the Original Issue Date of which is after a
Regular Record Date but prior to the applicable Interest Payment Date, shall be
the Interest Payment Date following the next succeeding Regular Record Date;
and provided, that interest payable on the Maturity Date set forth above or, if
applicable, upon redemption or acceleration, shall be payable to the Person to
whom principal shall be payable. Except as otherwise provided in the Indenture,

punctually paid or
duly provided for will forthwith cease to be payable to the Holder on such
Regular Record Date and shall be paid to the Person in whose name this Note is
registered at the close of business on a Special Record Date for the payment of
such defaulted interest to be fixed by the Trustee, notice whereof shall be
given to Noteholders not more than fifteen days nor fewer than ten days prior
to such Special Record Date. Payment of the principal of and interest and
premium on this Note shall be payable pursuant to Section 2.12(a) of the
Indenture.

 

This Note is a Global
Note in respect of a duly authorized issue of 6.125% Senior Secured Notes due
2017 (the “NOTES OF THIS SERIES”, which term includes any Global Notes
representing such Notes) of the Company issued and to be issued under an
Indenture dated as of June 1, 2006 between the Company and The Bank of New
York Trust Company, N.A., as trustee (herein called the “TRUSTEE”, which term
includes any successor Trustee under the Indenture) and indentures supplemental
thereto (collectively, the “INDENTURE”). Under the Indenture, one or more
series of notes may be issued and, as used herein, the term “Notes” refers to
the Notes of this Series. Reference is hereby made to the Indenture for a more
complete statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Noteholders and of
the terms upon which the Notes are and are to be authenticated and delivered.
This Note has been issued in respect of the series designated on the first page
hereof, issued in the initial aggregate principal amount of $250,000,000.

 

The Notes will be secured
by mortgage bonds (the “SENIOR NOTE MORTGAGE BONDS”) delivered by the Company
to the Trustee for the benefit of the Holders of the Notes, issued under the
General Mortgage Indenture and Deed of Trust, dated as of November 1, 1992
between the Company and The Bank of New York Trust Company, N.A. (formerly BNY
Midwest Trust Company), as successor trustee (the “MORTGAGE TRUSTEE”), as
supplemented and modified (collectively, the “MORTGAGE”). Reference is made to
the Mortgage and the Indenture for a description of the rights of the Trustee
as holder of the Senior Note Mortgage Bonds, the property mortgaged and
pledged, the nature and extent of the security and the rights of the holders of
mortgage bonds, under the Mortgage and the rights of the Company and of the
Mortgage Trustee in respect thereof, the duties and immunities of the Mortgage
Trustee and the terms and conditions upon which the Senior Note Mortgage Bonds
are secured and the circumstances under which additional mortgage bonds may be
issued.

 

So long as any of the
Notes of this Series are outstanding, the Company will not optionally redeem,
purchase or otherwise retire in full its outstanding Mortgage Bonds not subject
to the release provisions of the Indenture, and, therefore, the Release Date
will not occur.

 

Each Note of this Series
shall be dated and issued as of the date of its authentication by the Trustee
and shall bear an Original Issue Date. Each Note of this Series issued upon
transfer, exchange or substitution of such Note shall bear the Original Issue
Date of such transferred, exchanged or substituted Note, as the case may be.

 

Interest on this Note
will accrue from and including the Original Issue Date specified above to, but
excluding, May 15, 2008, and thereafter, from and including each Interest
Payment Date to, but excluding, the next succeeding Interest Payment Date or
the Maturity Date, as the case may be.

 

A-4

 

Interest payments for
this Note shall be computed on the basis of a 360-day year consisting of twelve
30-day months. If any Interest Payment Date falls on a day that is not a
Business Day, the Interest Payment Date will be the next succeeding Business
Day (and without any interest or other payment in respect of any such delay). If
the Maturity Date of this Note or any redemption date falls on a day that is
not a Business Day, the payment of principal, premium, if any, and interest
will be made on the next succeeding Business Day, and no interest on such
payment shall accrue for the period from and after the Maturity Date or such
redemption date.

 

All or a portion of the
Notes of this Series may be redeemed at the option of the Company at any time
or from time to time. The redemption price for the Notes of this Series to be
redeemed on any redemption date will be equal to the greater of the following
amounts: (a) 100% of the principal amount of the Notes of this Series
being redeemed on the redemption date; or (b) the sum of the present values of
the remaining scheduled payments of principal and interest on the Notes of this
Series being redeemed on that redemption date (not including any portion of any
payments of interest accrued to the redemption date) discounted to the
redemption date on a semiannual basis at the Adjusted Treasury Rate (as defined
below) plus 30 basis points, as determined by the Reference Treasury Dealer (as
defined below); plus, in each case, accrued and unpaid interest thereon to the
redemption date. Notwithstanding the foregoing, installments of interest on
Notes of this Series that are due and payable on Interest Payment Dates falling
on or prior to a redemption date will be payable on the Interest Payment Date
to the Holder of this Note as of the close of business on the relevant Regular
Record Date. The redemption price will be calculated on the basis of a 360-day
year consisting of twelve 30-day months.

 

The Company shall mail
notice of any redemption at least 30 days but not more than 60 days before the
redemption date to each Holder of the Notes of this Series to be redeemed.
Unless the Company defaults in payment of the redemption price, on and after
the redemption date, interest will cease to accrue on the Notes of this Series
or portions thereof called for redemption.

 

“ADJUSTED TREASURY RATE”
means, with respect to any redemption date, the rate per annum equal to the
semiannual equivalent yield to maturity of the Comparable Treasury Issue,
assuming a price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) equal to the Comparable Treasury Price for such
redemption date.

 

“COMPARABLE TREASURY
ISSUE” means the United States Treasury security selected by the Reference
Treasury Dealer as having a maturity comparable to the remaining term of the
Notes of this Series to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
term of such Notes of this Series.

 

“COMPARABLE TREASURY
PRICE” means, with respect to any redemption date, (A) the average of the
Reference Treasury Dealer Quotations for such redemption date, after excluding
the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the
Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the
average of all such quotations, or (C) if only one Reference Treasury Dealer
Quotation is received, such quotation.

 

A-5

 

“REFERENCE TREASURY
DEALER” means (A) Barclays Capital Inc., BNP Paribas Securities Corp., J.P.
Morgan Securities Inc. or Lazard Capital Markets LLC or their respective
affiliates which are primary U.S. Government securities dealers in New York
City (each, a “Primary Treasury Dealer”), and their respective successors;
provided, however, that if any of the foregoing shall cease to be a Primary
Treasury Dealer, the Company shall substitute therefor another Primary Treasury
Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Trustee
after consultation with the Company.

 

“REFERENCE TREASURY
DEALER QUOTATIONS” means, with respect to each Reference Treasury Dealer and
any redemption date, the average, as determined by the Trustee, of the bid and
asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Trustee by such
Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third
Business Day preceding such redemption date.

 

The Company, at its
option, and subject to the terms and conditions provided in the Indenture, will
be discharged from any and all obligations in respect of the Notes of this
Series (except for certain obligations including obligations to register the
transfer or exchange of Notes of this Series, replace stolen, lost or mutilated
Notes of this Series, maintain paying agencies and hold monies for payment in
trust, all as set forth in the Indenture) if the Company deposits with the
Trustee money, U.S. Government Obligations which through the payment of interest
thereon and principal thereof in accordance with their terms will provide
money, or a combination of money and U.S. Government Obligations, in any event
in an amount sufficient, without reinvestment, to pay all the principal of and
any premium and interest on the Notes of this Series on the dates such payments
are due in accordance with the terms of the Notes of this Series.

 

If an Event of Default
shall occur and be continuing with respect to the Notes, the principal of and
interest on the Notes may be declared due and payable in the manner and with
the effect provided in the Indenture and, upon such declaration, the Trustee
shall demand the redemption of the Senior Note Mortgage Bonds to the extent
provided in the Indenture.

 

The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the
modifications of the rights and obligations of the Company and the rights of
the Noteholders under the Indenture at any time by the Company and the Trustee
with the consent of the Holders of a majority in aggregate principal amount of
the outstanding Notes. Any such consent or waiver by the Holder of this Note
shall be conclusive and binding upon such Holder and upon all future Holders of
this Note and of any Note issued upon the registration of transfer hereof or in
exchange therefor or in lieu thereof whether or not notation of such consent or
waiver is made upon this Note.

 

As set forth in and
subject to the provisions of the Indenture, no Holder of any Notes will have
any right to institute any proceeding with respect to the Indenture or for any
remedy thereunder unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default with respect to such Notes, the
Holders of a majority in aggregate principal amount of the outstanding Notes
affected by such Event of Default shall have made written request and offered
reasonable indemnity to the Trustee to institute such proceeding as Trustee and
the Trustee shall have failed to institute such proceeding within 60 days;
provided, 

 

A-6

 

however, that such
limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal of and any premium or interest on this
Note on or after the respective due dates expressed herein.

 

No reference herein to
the Indenture and to provisions of this Note or of the Indenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to
pay the principal of and any premium and interest on this Note at the times,
places and rates and the coin or currency prescribed in the Indenture.

 

As provided in the
Indenture and subject to certain limitations therein set forth, this Note may
be transferred only as permitted by the legend hereto and the provisions of the
Indenture.

 

The Indenture and the
Notes shall be governed by, and construed in accordance with, the laws of the
State of New York without regard to conflicts of law principles thereof.

 

Unless the certificate of
authentication hereon has been executed by the Trustee, directly or through an
Authenticating Agent by manual signature of an authorized officer, this Note
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

 

All terms used in this
Note that are defined in the Indenture shall have the meanings assigned to them
in the Indenture unless otherwise indicated herein.

to make our investment decision. We acknowledge that we have read and agree to
the matters stated under the caption NOTICE TO INVESTORS in such Offering

Memorandum and the undersigned agrees to be bound by, and not to resell, pledge
or otherwise transfer the Notes except in compliance with such restrictions and
conditions and the Securities Act of 1933, as amended (the “Securities Act”).

 

3.             We
understand that the offer and sale of the Notes have not been registered under

of any accounts for which we are acting as hereinafter stated, that if we sell

[FORM OF REVERSE OF NOTE]

 

ILLINOIS POWER COMPANY

6.125% SENIOR SECURED NOTE DUE 2017

 

This Note is one of a
duly authorized issue of 6.125% Senior Secured Notes due 2017 (the “NOTES OF
THIS SERIES”) of the Company issued and to be issued under an Indenture dated
as of June 1, 2006, between the Company and The Bank of New York Trust
Company, N.A., as trustee (herein called the “TRUSTEE”, which term includes any
successor Trustee under the Indenture) and indentures supplemental thereto
(collectively, the “INDENTURE”). Under the Indenture, one or more series of
notes may be issued and, as used herein, the term “Notes” refers to the Notes
of this Series. Reference is hereby made to the Indenture for a more complete
statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Noteholders and of
the terms upon which the Notes are and are to be authenticated and delivered.
This Note is one of the series designated on the face hereof, issued in the
initial aggregate principal amount of $250,000,000.

 

The Notes will be secured
by mortgage bonds (the “SENIOR NOTE MORTGAGE BONDS”) delivered by the Company
to the Trustee for the benefit of the Holders of the Notes, issued under the
General  Mortgage Indenture and Deed of
Trust, dated as of November 1, 1992 between the Company and The Bank of
New York Trust Company, N.A. (formerly BNY Midwest Trust Company), as successor
trustee (the “MORTGAGE TRUSTEE”), as supplemented and modified (collectively,
the “MORTGAGE”). Reference is made to the Mortgage and the Indenture for a
description of the rights of the Trustee as holder of the Senior Note Mortgage
Bonds, the property mortgaged and pledged, the nature and extent of the
security and the rights of the holders of mortgage bonds, under the Mortgage
and the rights of the Company and of the Mortgage Trustee in respect thereof,
the duties and immunities of the Mortgage Trustee and the terms and conditions
upon which the Senior Note Mortgage Bonds are secured and the circumstances
under which additional mortgage bonds may be issued.

 

So long as any of the
Notes of this Series are outstanding, the Company will not optionally redeem,
purchase or otherwise retire in full its outstanding Mortgage Bonds not subject
to the release provisions of the Indenture, and, therefore, the Release Date
will not occur.

 

Each Note of this Series
shall be dated and issued as of the date of its authentication by the Trustee
and shall bear an Original Issue Date. Each Note of this Series issued upon
transfer, exchange or substitution of such Note shall bear the Original Issue
Date of such transferred, exchanged or substituted Note, as the case may be.

 

Interest on this Note
will accrue from and including the Original Issue Date specified above to, but
excluding, May 15, 2008, and thereafter, from and including each Interest
Payment Date to, but excluding, the next succeeding Interest Payment Date or
the Maturity Date, as the case may be.

 

Interest payments for
this Note shall be computed on the basis of a 360-day year consisting of twelve
30-day months. If any Interest Payment Date falls on a day that is not a
Business Day, the Interest Payment Date will be the next succeeding Business
Day (and without 

 

B-6

 

any interest or
other payment in respect of any such delay). If the Maturity Date of this Note
or any redemption date falls on a day that is not a Business Day, the payment
of principal, premium, if any, and interest will be made on the next succeeding
Business Day, and no interest on such payment shall accrue for the period from
and after the Maturity Date or such redemption date.

 

All or a portion of the
Notes of this Series may be redeemed at the option of the Company at any time
or from time to time. The redemption price for the Notes of this Series to be
redeemed on any redemption date will be equal to the greater of the following
amounts: (a) 100% of the principal amount of the Notes of this Series
being redeemed on the redemption date; or (b) the sum of the present values of
the remaining scheduled payments of principal and interest on the Notes of this
Series being redeemed on that redemption date (not including any portion of any
payments of interest accrued to the redemption date) discounted to the
redemption date on a semiannual basis at the Adjusted Treasury Rate (as defined
below) plus 30 basis points, as determined by the Reference Treasury Dealer (as
defined below); plus, in each case, accrued and unpaid interest thereon to the
redemption date. Notwithstanding the foregoing, installments of interest on Notes
of this Series that are due and payable on Interest Payment Dates falling on or
prior to a redemption date will be payable on the Interest Payment Date to the
Holder of this Note as of the close of business on the relevant Regular Record
Date. The redemption price will be calculated on the basis of a 360-day year
consisting of twelve 30-day months.

 

The Company shall mail
notice of any redemption at least 30 days but not more than 60 days before the
redemption date to each Holder of the Notes of this Series to be redeemed.
Unless the Company defaults in payment of the redemption price, on and after
the redemption date, interest will cease to accrue on the Notes of this Series
or portions thereof called for redemption.

 

“ADJUSTED TREASURY RATE”
means, with respect to any redemption date, the rate per annum equal to the
semiannual equivalent yield to maturity of the Comparable Treasury Issue,
assuming a price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) equal to the Comparable Treasury Price for such
redemption date.

 

“COMPARABLE TREASURY
ISSUE” means the United States Treasury security selected by the Reference
Treasury Dealer as having a maturity comparable to the remaining term of the
Notes of this Series to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
term of such Notes of this Series.

 

“COMPARABLE TREASURY PRICE”
means, with respect to any redemption date, (A) the average of the Reference
Treasury Dealer Quotations for such redemption date, after excluding the
highest and lowest such Reference Treasury Dealer Quotations, or (B) if the
Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the
average of all such quotations, or (C) if only one Reference Treasury Dealer
Quotation is received, such quotation.

 

“REFERENCE TREASURY
DEALER” means (A) Barclays Capital Inc., BNP Paribas Securities Corp., J.P.
Morgan Securities Inc. or Lazard Capital Markets LLC or their respective 

 

B-7

 

affiliates which
are primary U.S. Government securities dealers in New York City (each, a “Primary
Treasury Dealer”), and their respective successors; provided, however, that if
any of the foregoing shall cease to be a Primary Treasury Dealer, the Company
shall substitute therefor another Primary Treasury Dealer; and (B) any other
Primary Treasury Dealer(s) selected by the Trustee after consultation with the
Company.

 

“REFERENCE TREASURY
DEALER QUOTATIONS” means, with respect to each Reference Treasury Dealer and
any redemption date, the average, as determined by the Trustee, of the bid and
asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Trustee by such
Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third
Business Day preceding such redemption date.

 

The Company, at its
option, and subject to the terms and conditions provided in the Indenture, will
be discharged from any and all obligations in respect of the Notes of this
Series (except for certain obligations including obligations to register the
transfer or exchange of Notes of this Series, replace stolen, lost or mutilated
Notes of this Series, maintain paying agencies and hold monies for payment in
trust, all as set forth in the Indenture) if the Company deposits with the
Trustee money, U.S. Government Obligations which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money, or a combination of money and U.S. Government Obligations, in
any event in an amount sufficient, without reinvestment, to pay all the principal
of and any premium and interest on the Notes of this Series on the dates such
payments are due in accordance with the terms of the Notes of this Series.

 

If an Event of Default
shall occur and be continuing with respect to the Notes, the principal of and
interest on the Notes may be declared due and payable in the manner and with
the effect provided in the Indenture and, upon such declaration, the Trustee
shall demand the redemption of the Senior Note Mortgage Bonds to the extent
provided in the Indenture.

 

The Indenture permits,
with certain exceptions as therein provided, the amendment thereof and the
modifications of the rights and obligations of the Company and the rights of
the Noteholders under the Indenture at any time by the Company and the Trustee
with the consent of the Holders of a majority in aggregate principal amount of
the outstanding Notes. Any such consent or waiver by the Holder of this Note
shall be conclusive and binding upon such Holder and upon all future Holders of
this Note and of any Note issued upon the registration of transfer hereof or in
exchange therefor or in lieu thereof whether or not notation of such consent or
waiver is made upon this Note.

 

As set forth in and
subject to the provisions of the Indenture, no Holder of any Notes will have
any right to institute any proceeding with respect to the Indenture or for any
remedy thereunder unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default with respect to such Notes, the
Holders of a majority in aggregate principal amount of the outstanding Notes
affected by such Event of Default shall have made written request and offered
reasonable indemnity to the Trustee to institute such proceeding as Trustee and
the Trustee shall have failed to institute such proceeding within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the 

 

B-8

 

enforcement of
payment of the principal of and any premium or interest on this Note on or
after the respective due dates expressed herein.

 

No reference herein to
the Indenture and to provisions of this Note or of the Indenture shall alter or
impair the obligation of the Company, which is absolute and unconditional, to
pay the principal of and any premium and interest on this Note at the times,
places and rates and the coin or currency prescribed in the Indenture.

 

As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of
this Note is registrable in the Note register. Upon surrender of this Note for
registration or transfer at the corporate trust office of the Trustee or such
other office or agency as may be designated by the Company in the Borough of
Manhattan, the City and State of New York, or Chicago, Illinois, endorsed by or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Note registrar, duly executed by the Holder hereof or the
attorney in fact of such Holder duly authorized in writing, one or more new
Notes of this Series of like tenor and of authorized denominations and for the
same aggregate principal amount will be issued to the designated transferee or
transferees.

 

The Notes of this Series
are issuable only in registered form, without coupons, in denominations of
$1,000 and integral multiples of $1,000 thereof. As provided in the Indenture
and subject to certain limitations therein set forth, Notes of this Series are
exchangeable for a like aggregate principal amount of Notes of this Series of
like tenor and of a different authorized denomination, as requested by the
Holder surrendering the same.

 

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

 

Prior to due presentment
of this Note for registration of transfer, the Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name this
Note is registered as the owner thereof for all purposes, whether or not this
Note is overdue, and neither the Company, the Trustee nor any such agent shall
be affected by notice to the contrary.

 

The Indenture and the
Notes shall be governed by, and construed in accordance with, the laws of the
State of New York without regard to conflicts of law principles thereof.

 

All terms used in this
Note that are defined in the Indenture shall have the meanings assigned to them
in the Indenture unless otherwise indicated herein.

[FORM OF INSTITUTIONAL ACCREDITED INVESTOR CERTIFICATE]*

 

[Transferor
Name and Address]

 

Ladies
and Gentlemen:

 

In
connection with our proposed purchase of 6.125% Senior Secured Notes due 2017
(the “Notes”) issued by Illinois Power Company d/b/a AmerenIP (the “Issuer”),
we confirm that:

 

1.             We
have received a copy of the Offering Memorandum (the “Offering Memorandum”)
relating to the Notes and such other information as we deem necessary in order
to make our investment decision. We acknowledge that we have read and agree to
the matters stated under the caption NOTICE TO INVESTORS in such Offering
Memorandum.

 

2.             We
understand that any subsequent transfer of the Notes is subject to certain
restrictions and conditions set forth in the indenture relating to the Notes
(the “Indenture”) and as set forth under NOTICE TO INVESTORS in the Offering
Memorandum and the undersigned agrees to be bound by, and not to resell, pledge
or otherwise transfer the Notes except in compliance with such restrictions and
conditions and the Securities Act of 1933, as amended (the “Securities Act”).

 

3.             We
understand that the offer and sale of the Notes have not been registered under
the Securities Act, and that the Notes may not be offered or sold except as
permitted in the following sentence. We agree, on our own behalf and on behalf
of any accounts for which we are acting as hereinafter stated, that if we sell
any Notes, we will do so only (A) to the Issuer, (B) so long as the Notes are
eligible for resale pursuant to Rule 144A under the Securities Act (“Rule 144A”),
to a person whom we reasonably believe is a “qualified institutional buyer”
within the meaning of Rule 144A that purchases for its own account or for the
account of a qualified institutional buyer to whom notice is given that the
resale, pledge or other transfer is being made in reliance on Rule 144A, (C) to
an institutional “accredited investor” (as defined below) that, prior to such
transfer, furnishes to the Trustee (as defined in the Indenture) a signed
letter containing certain representations and agreements relating to the
restrictions on transfer of the Notes (substantially in the form of this
letter), (D) in an offshore transaction in accordance with Rule 904 of
Regulation S under the Securities Act, (E) pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (if available), or
(F) in accordance with another applicable exemption from the registration
requirements of, or in a transaction not subject to, the Securities Act or
pursuant to an effective registration statement under the Securities Act, and
we further agree to provide to any person purchasing any of the Notes from us a
notice advising such purchaser that resales of the Notes are restricted as
stated herein.

 

*  Include this
form only in a Private Note.

4.             We
understand that, on any proposed resale of any Notes, we will be required to
furnish to the Trustee and the Issuer such certification and other information
as the Trustee and the Issuer may reasonably require to confirm that the
proposed sale complies with the foregoing restrictions. We further understand
that the Notes purchased by us will bear a legend to the foregoing effect.

 

5.             We
are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2),
(3) or (7) under the Securities Act) and have such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of our investment in the Notes, and we and any accounts for which we are
acting are each able to bear the economic risk of our or its investment.

 

6.             We
are acquiring the Notes purchased by us for our own account or for one or more
accounts (each of which is an institutional “accredited investor”) as to each
of which we exercise sole investment discretion in each case for investment and
not with a view to, or for offer or sale in connection with, any distribution
in violation of the Securities Act.

 

You,
the Issuer and the Trustee are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceeding or official inquiry
with respect to the matters covered hereby.

 

	
   

  	
  Very
  truly yours,
