ARTICLE I

DESCRIPTION OF THE SERIES AA mortgage bonds.

Section 1.               The Company hereby creates a new series
of Bonds to be known as “Mortgage Bonds, Senior Notes Series AA” (the “Series AA
Mortgage Bonds”). The Series AA Mortgage Bonds shall be executed,
authenticated and delivered in accordance with the provisions of, and shall in
all respects be subject to, all of the terms, conditions and covenants of the
Indenture, as supplemented and modified. The Series AA Mortgage Bonds
shall be issued in the name of the Senior Note Trustee under the Senior Note
Indenture to secure any and all of the Company’s obligations under the Senior
Notes and any other series of senior notes from time to time outstanding under
the Senior Note Indenture.

The Series AA Mortgage Bonds shall be dated as provided in Section 3.03
of Article Three of the Indenture. The Series AA Mortgage Bonds shall
mature on June 15, 2016, shall accrue interest from the dates set forth in
the Senior Notes and shall bear interest at the same rate of interest as the
Senior Notes. Interest on the Series AA Mortgage Bonds is payable on the
same dates as interest on the Senior Notes is paid, until the principal sum is
paid in full.

Upon any payment of the
principal of, premium, if any, and interest on, all or any portion of the
Senior Notes, whether at maturity or prior to maturity by redemption or
otherwise or upon provision for the payment thereof having been made in
accordance with Section 5.01(a) of the Senior Note Indenture, the Series AA Mortgage Bonds in
a principal amount equal to the principal amount of such Senior Notes shall, to
the extent of such payment of principal, premium, if any, and interest, be
deemed paid and the obligation of the Company thereunder to make such payment
shall be discharged to such extent and, in the case of the payment of 

 3
 

 

principal (and premium,
if any), such Series AA
Mortgage Bonds shall be surrendered to the Company for cancellation as
provided in Section 4.08 of the Senior Note Indenture. The Trustee may at
any time and all times conclusively assume that the obligation of the Company
to make payments with respect to the principal of, premium, if any, and
interest on the Senior Notes, so far as such payments at the time have become
due, has been fully satisfied and discharged pursuant to the foregoing sentence
unless and until the Trustee shall have received a written notice from the Senior
Note Trustee signed by one of its officers stating (i) the timely payment
of principal, or premium, if any, or interest on, the Senior Notes has not been
made, (ii) that the Company is in arrears as to the payments required to
be made by it to the Senior Note Trustee pursuant to the Senior Note Indenture,
and (iii) the amount of the arrearage.

ILLINOIS POWER COMPANY, a corporation organized and existing under the
laws of the State of Illinois (the “Company”), which term shall include any
successor corporation as defined in the Indenture hereinafter referred to, for
value received, hereby promises to pay to The Bank of New York Trust Company,
N.A., as trustee (the “Senior Note Trustee”) under the Indenture dated as of June 1,
2006 (the “Senior Note Indenture”), relating to the Company’s 6.25% Senior
Secured Notes due 2016 (the “Senior Notes”) in the aggregate principal amount
of $75,000,000, between the Company and the Senior Note Trustee, or registered
assigns, the principal sum of $75,000,000 on June 15, 2016, in any coin or
currency of the United States of America, which at the time of payment is legal
tender for public and private debts, and to pay interest thereon in like coin
or currency from the date of issuance (and thereafter from the dates set forth
in the Senior Notes), and at the same rate of interest as the Senior Notes. Interest
on overdue principal, premium, if any, and, to the extent permitted by law, on
overdue interest, shall be payable at the interest rate payable on the Senior
Notes. Interest on this Mortgage Bond is payable on the same dates as interest
on the Senior Notes is paid, until the principal sum of this Mortgage Bond is
paid in full. Pursuant to Article IV of the Senior Note Indenture, this
Mortgage Bond is issued to the Senior Note Trustee to secure any and all
obligations of the Company under the Senior Notes and any other series of
senior notes from time to time 

 4
 

 

outstanding under the Senior Note Indenture. Payment of principal of,
or premium, if any, or interest on, the Senior Notes shall constitute payments
on this Mortgage Bond as further provided herein and in the Supplemental
Indenture of June 1, 2006 (as hereinafter defined) pursuant to which this
Mortgage Bond has been issued. Both the principal of, premium, if any, and the
interest on, this Mortgage Bond are payable at the office of the Senior Note
Trustee.

Upon any payment of the
principal of, premium, if any, and
interest on, all or any portion of the Senior Notes, whether at maturity or
prior to maturity by redemption or otherwise or upon provision for the payment
thereof having been made in accordance with Section 5.01(a) of the
Senior Note Indenture, a principal amount of this Mortgage Bond equal to the
principal amount of such Senior Notes shall, to the extent of such payment of
principal, premium, if any, and interest, be deemed paid and the obligation of the
Company thereunder to make such payment shall be discharged to such extent and,
in the case of the payment of principal (and premium, if any), such Mortgage
Bonds shall be surrendered to the Company for cancellation as provided in Section 4.08
of the Senior Note Indenture. The Trustee (as hereinafter defined) may at any
time and all times conclusively assume that the obligation of the Company to
make payments with respect to the principal of,
premium, if any, and interest on, the Senior Notes, so far as such
payments at the time have become due, has been fully satisfied and discharged
pursuant to the foregoing sentence unless and until the Trustee shall have
received a written notice from the Senior Note Trustee signed by one of its
officers stating (i) that timely payment of principal of, premium, if any, or interest on, the
Senior Notes has not been made, (ii) that the Company is in arrears as to
the payments required to be made by it to the Senior Note Trustee pursuant to
the Senior Note Indenture, and (iii) the amount of the arrearage.

For purposes of Section 4.09 of the Senior Note Indenture, this
Mortgage Bond shall be deemed to be the “Related Series of Senior Note
Mortgage Bonds” in respect of the Senior Notes.

This Mortgage Bond shall not be entitled to any benefit under the
Indenture or any indenture supplemental thereto, or become valid or obligatory
for any purpose, until the form of certificate endorsed hereon shall have been
signed by or on behalf of BNY Midwest Trust Company, as successor trustee to
Harris Trust and Savings Bank, the Trustee under the Indenture, or a successor
trustee thereto under the Indenture (the “Trustee”).

The provisions of this Mortgage Bond are continued on the reverse
hereof and such continued provisions shall for all purposes have the same
effect as though fully set forth at this place.

[FORM OF REVERSE OF BOND]

This Mortgage Bond is one of a duly authorized issue of Mortgage Bonds
of the Company (the “Mortgage Bonds”) in unlimited aggregate principal amount,
of the series hereinafter specified, all issued and to be issued under and
equally secured by the General Mortgage Indenture and Deed of Trust (the “Indenture”),
dated as of November 1, 1992, executed by the Company to BNY Midwest Trust
Company, as successor trustee to Harris Trust and Savings Bank (the “Trustee”)
to which Indenture and all indentures supplemental thereto reference is hereby
made for a description of the properties mortgaged and pledged, the nature and
extent of the security, the rights of registered owners of the Mortgage Bonds
and of the Trustee in respect thereof, and the terms and conditions upon which
the Mortgage Bonds are, and are to be, secured. The Mortgage Bonds may be
issued in series, for various principal sums, may mature at different times,
may bear interest at different rates and may otherwise vary as provided in the
Indenture. This Mortgage Bond is one of a series designated as the Series AA
Mortgage Bonds of the Company, unlimited in aggregate principal amount, issued
under and secured by the Indenture and described in the Supplemental Indenture
dated as of June 1, 2006 (the “Supplemental Indenture of June 1, 2006”
), between the Company and the Trustee, supplemental to the Indenture.

This Series AA Mortgage Bond is subject to redemption in
accordance with the terms of Article II of the Supplemental Indenture of June 1,
2006.

As provided in Section 4.11
of the Senior Note Indenture, from and after the Release Date (as defined in
the Senior Note Indenture), the obligations of the Company with respect to the Series AA Mortgage Bonds
shall be deemed to be satisfied and discharged, the Series AA Mortgage Bonds shall cease to secure in any
manner any Senior Notes outstanding under the Senior Note Indenture, and,
pursuant to Section 4.08 of the Senior Note Indenture, the Senior Note
Trustee shall forthwith deliver the Series AA
Mortgage Bonds to the Company for cancellation.

In case an Event of Default, as defined in the Indenture, shall occur,
the principal of all Mortgage Bonds at any such time outstanding under the
Indenture may be declared or may become due and payable, upon the conditions
and in the manner and with the effect provided in the Indenture. The Indenture
provides that such declaration may be rescinded under certain circumstances.

ARTICLE II

REDEMPTION.

Section 1.           The Series AA Mortgage Bonds
are not redeemable except on the date, in the principal amount and for the
redemption price that correspond to the redemption date for, the principal
amount to be redeemed of, and the redemption price for, the Senior Notes, and
except as set forth in Section 2 of this Article II.

In the event that
the Company redeems any Senior Notes prior to maturity in accordance with the
provisions of the Senior Note Indenture, the Senior Note Trustee shall on the
same date deliver to the Company the Series AA Mortgage Bonds in principal
amount corresponding to the Senior Notes so redeemed, as provided in Section 4.08
of the Senior Note Indenture. The Company agrees to give the Trustee notice of
any such redemption of the Senior Notes on or before the date fixed for any
such redemption.

Section 2.           Upon
the occurrence of an Event of Default under the Senior Note Indenture (as
defined therein) and the acceleration of the Senior Notes, the Series AA
Mortgage Bonds shall be redeemable in whole upon receipt by the Trustee (with a
copy to the Company) of a written demand (hereinafter called a “Redemption
Demand”) from the Senior Note Trustee stating that there has occurred under the
Senior Note Indenture both an Event of Default and a declaration of
acceleration of payment of principal, accrued interest and premium, if any, on
the Senior Notes specifying the last date to which interest on such Senior
Notes has been paid (such date being hereinafter referred to as the “Initial
Interest Accrual Date”) and demanding redemption of the Series AA Mortgage
Bonds. The Company waives any right it may have to prior notice of such
redemption under the Indenture. Upon surrender of the Series AA Mortgage
Bonds by the Senior Note Trustee to the Trustee, the Series AA Mortgage
Bonds shall be redeemed at a redemption price equal to the principal amount
thereof plus accrued interest thereon from the Initial Interest Accrual Date to
the redemption date; provided, however, that in the event of a rescission or
annulment of acceleration of the Senior Notes pursuant to the last paragraph of
Section 8.01(a) of the Senior Note Indenture, then any Redemption
Demand shall thereby be deemed to be rescinded by the Senior Note Trustee
although no such rescission or annulment shall extend to or affect any
subsequent default or impair any right consequent thereon.

ARTICLE III

ISSUE OF THE SERIES AA MORTGAGE BONDS.

Section 1.               The Company hereby exercises the right
to obtain the authentication of $75,000,000 principal amount of additional
Bonds pursuant to the terms of Section 4.04 of the Indenture, all of which
shall be Series AA Mortgage Bonds. Except as provided below in connection
with the Release Date (as defined in the Senior Note Indenture), the principal
amount of the Series AA Mortgage Bonds outstanding from time to time shall
always be equal to the principal amount of the Senior Notes which are
outstanding from time to time under the Senior Note Indenture and to the extent
the Senior Note Trustee holds Series AA Mortgage Bonds in excess of such
principal amount, such Series AA Mortgage Bonds shall be deemed cancelled
and retired and no longer outstanding under the Indenture.

Section 2.               Such Series AA Mortgage Bonds may
be authenticated and delivered prior to the filing for recordation of this
Supplemental Indenture.

 8
 

 

Section 3.               For purposes of Section 4.09
of the Senior Note Indenture, the Series AA Mortgage Bonds shall be deemed to be the “Related
Series of Senior Notes Mortgage Bonds” in respect of the Senior Notes.

Section 4.               As provided in Section 4.11
of the Senior Note Indenture, from and after the Release Date (as defined in
the Senior Note Indenture), the obligations of the Company with respect to the Series AA Mortgage Bonds
shall be deemed to be satisfied and discharged, the Series AA Mortgage Bonds shall cease to secure in any
manner any Senior Notes outstanding under the Senior Note Indenture, and,
pursuant to Section 4.08 of the Senior Note Indenture, the Senior Note
Trustee shall forthwith deliver the Series AA
Mortgage Bonds to the Company for cancellation.

ARTICLE IV

Global
Management Incentive Plan

Section 4.3(b), as amended June 15,
2006

4.3           Determination of Amounts Payable Under Performance
Awards. The potential amount payable under a Performance Award
granted to a Participant for a Fiscal Year, if any, shall be determined by the
Committee in its sole discretion based upon the attainment of Performance Goals
established by the Committee.

(a)           Amount
of Performance Award. A Participant’s Performance Award under the
Plan shall be calculated by multiplying the Participant’s Bonus Percentage (as
determined under this section 4.3) times the Participant’s Base Salary.

(i)                                     Mid-Year
Period Performance Awards. A Mid-Year Period Performance Award shall be based
solely on Mid-Year Financial Goals. The maximum amount that may be paid under a
Mid-Year Period Performance Award is 50% of the target amount applicable to the
Financial Goals. If the planned PBT for the Mid-Year Period is $0 or less, no
Mid-Year Period Performance Award relating to the PBT Goal shall be awarded.

(ii)                                  Year-End
Period Performance Awards. A Year-End Period Performance Award shall be based
on achievement of Financial and the Business Goals. A Year-End Period
Performance Award shall be determined by calculating a Participant’s
Performance Award for the Fiscal Year and subtracting the amount of the
Participant’s Mid-Year Period Performance Award, if any.

(b)           Bonus Percentage. Until the Board or
Committee determines otherwise, the following Target Bonus Percentages shall
apply to the Participants who hold the following positions:

	
  Target Bonus

  55

  	
  %

  	
   

  	
  Other Participants

  	
   

  

 

As soon as
administratively practicable after the relevant Award Period, the Committee
will ascertain the extent to which the Performance Goals applicable to
Performance Awards made for that Award Period have been achieved. The Company
shall retain with the records of the Company documentation of its conclusions,
and the

 

basis
for its conclusions, concerning the extent to which Performance Goals were
achieved. Subject to Sections 4.5 and 4.6, if the Committee certifies that
a Participant has achieved his Performance Goals he shall be entitled to
receive a Performance Award with respect to such Performance Goals in an amount
determined as follows:

(i)                                     PBT Goals. A Participant’s Bonus
Percentage will increase or decrease based on the attainment of the relevant
PBT Goal in accordance with the following schedule:

The Threshold
Performance Level must be must be attained for a Participant to be entitled to
receive a Performance Award based on the Financial Goals. If the Threshold
Performance Level is attained, a Participant will earn 25% of their Target
Bonus as it relates to that portion of their Performance Award. The portion of
a Performance Award based on a PBT Goal is earned separately from the
attainment of the ROI Goal. The maximum payout under a Performance Award is two
times (2X) the Target Bonus.

If the relevant annual PBT
Goal as submitted to and approved by the Board is $0 or less, the following rules shall
apply:

(1)           the PBT Goal must be
earned before any Performance Award related to the relevant PBT Goal is paid,
and

(2)           the maximum payout
is the Target Bonus.

(ii)           ROI
Goals. The portion of a Performance Award based on the ROI Goal will
increase or decrease based on the attainment of the relevant ROI Goal, as
determined by the Board or the Committee. The Threshold Performance Level must
be attained for a Participant to be entitled to receive a Performance Award
based on the ROI Goal. If the Threshold Performance Level is attained, a
Participant will earn 25% of their Target Bonus as it relates to that portion
of their Performance Award. The portion of a Performance Award based on an ROI
Goal is earned separately from the attainment of the PBT Goal(s). The maximum
payout under a Performance Award is two times (2X) the Target Bonus.

 

The Target Performance
Level for ROI will be equal to the ROI planned in the Profit Plan, but the
Threshold and Overachievement Performance Levels for ROI will be set by the
Board.

If the planned ROI is 0%
or less, the Committee may:

(1)           eliminate the ROI
goal and replace it by increasing the weighting of the PBT goal, or

(2)           establish a ROI target
higher than the planned percentage, and establish related Threshold and
Overachievement levels.

(iii) Business Goals. The portion of a
Performance Award based on a Business Goal is earned separately from the
attainment of the Financial Goals unless the Financial Goals are exceeded. If
the Financial Goals are exceeded, the portion of the Performance Award based on
the Business Goals will be calculated based on the level of achievement of the
Financial Goals.
