Illinois, formerly Continental Bank, National Association and formerly
Continental Illinois National Bank and Trust Company of Chicago, and
hereinafter referred to as the “Trustee”) and Edmond B. Stofft, as Trustees,
and the indentures supplemental thereto heretofore executed and delivered by
the Company to the Trustees under said indenture of mortgage, including the
indenture supplemental thereto dated November 1, 2005, executed and delivered
by the Company to said U.S. Bank National Association and Richard Prokosch
(successor Co-Trustee), as Trustees (collectively the “Trustees”), prior to the
authentication of this bond (said indenture of mortgage and said supplemental
indentures being hereinafter referred to, collectively, as the “Indenture”).  Reference to the Indenture and to all
supplemental indentures, if any, hereafter executed pursuant to the Indenture
is hereby made for a description of the property mortgaged and pledged, the
nature and extent of the security and the rights of the holders and registered
owners of said bonds and of the Trustees and of the Company in respect of such
security.  By the 


 


3





















 


terms of the Indenture,
the bonds to be secured thereby are issuable in series which may vary as to
date, amount, date of maturity, rate of interest, redemption provisions, medium
of payment and in other respects as in the Indenture provided.


 


This bond is one of a series of bonds of the Company
issued under the Indenture and designated as First Mortgage Bonds, Pollution
Control Series No. 19 (hereinafter called the “bonds of Series No. 19” or the “bonds
of said Series”).  The bonds of Series
No. 19 have been issued to the County Trustee under the County Indenture to
secure payment of the Environmental Facilities Revenue Bonds, 2005 Series B
(Kentucky Utilities Company Project) (the “Revenue Bonds”), issued by the
County under the County Indenture, the proceeds of which (other than any
accrued interest thereon) have been loaned to the Company pursuant to the
provisions of the Loan Agreement dated as of October 1, 2005 (the “Agreement”),
between the Company and the County.


 


Except as provided in the next succeeding paragraph,
in the event of a default under Section 9.1 of the Agreement or in the event of
a default in the payment of the principal of, premium, if any, or interest (and
such default in the payment of interest continues for the full grace period, if
any, permitted by the County Indenture and the Revenue Bonds) on the Revenue
Bonds, whether at maturity, by tender for purchase, by acceleration, by sinking
fund, redemption or otherwise, as and when the same becomes due, the bonds of
Series No. 19  shall be redeemable in whole upon receipt by the
Trustee of a written demand (hereinafter called a “Redemption Demand”) from the
County Trustee stating that there has been such a default, stating that it is
acting pursuant to the authorization granted by Section 9.02(c) of the County
Indenture, specifying the last date to which interest on the Revenue Bonds has
been paid (such date being hereinafter referred to as the “Initial Interest
Accrual Date”) and demanding redemption of the bonds of Series No. 19.  The Trustee shall, within 10 days after
receiving such Redemption Demand, mail a copy thereof to the Company marked to
indicate the date of its receipt by the Trustee.  Promptly upon receipt by the Company of such
copy of a Redemption Demand, the Company shall fix a date on which it will
redeem the bonds of Series No. 19 so demanded to be redeemed (hereinafter
called the “Demand Redemption Date”). 
Notice of the date fixed as and for the Demand Redemption Date shall be
mailed by the Company to the Trustee at least 30 days prior to such Demand
Redemption Date.  The date to be fixed by
the Company as and for the Demand Redemption Date may be any date up to and
including the earlier of (i) the 120th day after receipt by the Trustee of the
Redemption Demand or (ii) June 1, 2035, provided that if the Trustee shall not
have received such notice fixing the Demand Redemption Date within 90 days
after receipt by it of the Redemption Demand, the Demand Redemption Date shall
be deemed to be the earlier of (i) the 120th day after receipt by the Trustee
of the Redemption Demand or (ii) June 1, 2035. 
The Trustee shall mail notice of the Demand Redemption Date (such notice
being hereinafter called the “Demand Redemption Notice”) to the County Trustee
not more than 10 nor less than five days prior to the Demand Redemption
Date.  Notwithstanding the foregoing, if
a default to which this paragraph is applicable is existing on June 1, 2035,
such date shall be deemed to be the Demand Redemption Date without further
action (including actions specified in this paragraph) by the County Trustee,
the Trustee or the Company.  The bonds of
Series No. 19 shall be redeemed by the Company on the Demand Redemption Date,
upon surrender thereof by the County Trustee to the Trustee, at a redemption
price equal to the principal amount thereof plus accrued interest thereon at
the rate or rates then applicable to the Revenue Bonds or 


 


4





















 


determined under the
provisions of the County Indenture from the Initial Interest Accrual Date to
the Demand Redemption Date.  If a
Redemption Demand is rescinded by the County Trustee by written notice to the
Trustee prior to the Demand Redemption Date, no Demand Redemption Notice shall
be given, or, if already given, shall be automatically annulled, and interest
on the bonds of Series No. 19 shall cease to accrue, all interest accrued
thereon shall be automatically rescinded and cancelled and the Company shall
not be obligated to make any payments of principal of or interest on the bonds
of said Series; but no such rescission shall extend to or affect any subsequent
default or impair any right consequent thereon.


 


In the event that all of the bonds outstanding under
the Indenture shall have become immediately due and payable, whether by
declaration or otherwise, and such acceleration shall not have been annulled,
the bonds of Series No. 19 shall bear interest at the rate or rates applicable
to the Revenue Bonds from the Initial Interest Accrual Date, as specified in a
written notice to the Trustee from the County Trustee, and the principal of and
interest on the bonds of said Series from the Initial Interest Accrual Date
shall be payable in accordance with the provisions of Article X of the
Indenture.


 


Upon payment of the principal of and premium, if any,
and interest on the Revenue Bonds, whether at maturity or prior to maturity by
redemption or otherwise, and the surrender thereof to and cancellation thereof
by the County Trustee (other than any Revenue Bond that was cancelled by the
County Trustee and for which one or more other Revenue Bonds were delivered and
authenticated pursuant to the County Indenture in lieu of or in exchange or
substitution for such cancelled Revenue Bond), or upon provision for the
payment thereof having been made in accordance with the County Indenture, bonds
of Series No. 19 in a principal amount equal to the principal amount of the
Revenue Bonds so surrendered and cancelled or for the provision for which
payment has been made shall be deemed fully paid and the obligations of the
Company thereunder shall be terminated, and such bonds of Series No. 19 shall
be surrendered by the County Trustee to the Trustee and shall be cancelled by
the Trustee.  From and after the Release
Date (as defined below), the bonds of Series No. 19 shall be deemed fully paid,
satisfied and discharged and the obligations of the Company hereunder and
thereunder shall be terminated.   The
Release Date shall be the date that the Bond Insurer (as such term is defined
in the County Indenture), at the request of the Company, consents to the
release of the bonds of this Series, as security for the Revenue Bonds,
provided that in no event shall that date be later than the date as of which
all bonds issued under the Indenture prior to the date of initial issuance of
this bond (and excluding bonds of Series Nos. 11, 12, 13, 14, 15, 16, 17,
18 and 19) have been retired through payment, redemption or otherwise
(including those bonds “deemed to be paid” within the meaning of that term as
used in Article XII of the Indenture) at, before or after the maturity
thereof.  On the Release Date, the bonds
of Series No. 19 shall be surrendered by the County Trustee to the Trustee
whereupon the bonds of Series No. 19 so surrendered shall be cancelled by the
Trustee.


 


No recourse shall be had for the payment of the
principal of or interest on this bond, or for any claim based hereon, or
otherwise in respect hereof or of the Indenture or any indenture supplemental
thereto, to or against any incorporator, stockholder, officer or director,
past, present or future, of the Company, or of any predecessor or successor
corporation, either directly or through the Company or such predecessor or
successor corporation, under any constitution or 


 


5





















 


statute or rule of law,
or by the enforcement of any assessment or penalty, or otherwise, all such
liability of incorporators, stockholders, directors and officers being waived
and released by the registered owner hereof by the acceptance of this bond and
being likewise waived and released by the terms of the Indenture.


 


This bond is nontransferable except as may be required
to effect a transfer to any successor trustee under the County Indenture.  Any such transfer may be made by the
registered owner hereof, in person or by attorney duly authorized, at the
principal office or place of business of the Trustee under the Indenture, upon
the surrender and cancellation of this bond and the payment of any stamp tax or
other governmental charge, and upon any such transfer a new registered bond or
bonds without coupons, of the same series and for the same aggregate principal
amount, will be issued to the transferee in exchange herefor.

bonds of Series No. 19 (whether in temporary or definitive form) a certificate
of the Trustee substantially in the following form, to-wit:

America which at the time of payment is legal tender for public and private
debts.


 


The bonds of said Series shall be deemed fully paid,

extent and in the manner provided in Section 4 of this Article.


 


Section 3.  (a)  Except as provided in paragraph
(b) of this Section 3, in the event of a default under Section 9.1 of the
Agreement or in the event of a default in the payment of the principal of,

continues for the full grace period, if any, permitted by the County Indenture

Demand, rescission or notice shall be of no force or effect, unless it is
executed in the name of the County Trustee by one of its Vice-Presidents.


 


Section 4.  Upon payment of the principal of and premium,
if any, and interest on the Revenue Bonds, whether at maturity or prior to

date of initial issuance of the bonds of said Series (and excluding bonds of
said Series and First Mortgage Bonds, Pollution Control Series Nos. 11, 12, 13,
14, 15, 16, 17 and 18) have been retired through payment, redemption or

ARTICLE II.


 


Section 1.  The bonds of Series No. 19 shall be executed
on behalf of the Company and sealed with the corporate seal of the Company, all
in the manner provided in or permitted by Section 6 of Article I of the
Indenture, as follows:


 


(a)           bonds
of said Series executed on behalf of the Company by its President or a
Vice-President and by its Secretary or an Assistant Secretary may be so
executed by the manual or facsimile signature of such President or
Vice-President and of such Secretary or Assistant Secretary, as the case may
be, of the Company, or of any person or persons who shall have been such
officer or officers, as the case may be, of the Company on or subsequent to the
date of this supplemental indenture, notwithstanding that he or they may have
ceased to be such officer or officers of the Company at the time of the actual
execution, authentication, issue or delivery of any of such bonds, and any such
manual or facsimile signature or signatures of such officer or officers of the
Company, as above provided, on any such bonds shall constitute execution of
such bonds on behalf of the Company by such officer or officers of the Company
for the purposes of the Indenture, as hereby modified and amended, and shall be
valid and effective for all purposes, provided that
all bonds of said Series shall always be executed on behalf of the Company by
the manual or facsimile signature of its President or a Vice-President and of
its Secretary or an Assistant Secretary, as above provided, and provided, further, that none of such bonds shall be
executed on behalf of the Company by the manual or facsimile signature of the
same officer or person acting in more than one capacity; and


 


(b)           such
corporate seal of the Company may be facsimile, and the bonds of said Series on
which such facsimile seal of the Company shall be affixed, impressed, imprinted
or reproduced shall be deemed to be sealed with the corporate seal of the
Company for the purposes of the Indenture as hereby modified and amended, and such
facsimile seal shall be valid and effective for all purposes.


 


ARTICLE III.


 


Section 10 of Article III of the Indenture is hereby
further amended to provide that the Company agrees to observe and comply with
the provisions of said section as so amended hereby so long as the bonds of
Series No. 19 are outstanding.  The bonds
outstanding on the date hereof to which said Section 10 applies are Series P,
No. 10, Series S, and Nos. 11, 12, 13, 14, 15, 16, 17 and 18.


 


No covenant to provide a maintenance and renewal fund
is made in respect of the bonds of Series No. 19.  The absence of such a covenant shall not,
however, limit the right of the Company to use, apply or certify bonds of
Series No. 19 to comply with, or to satisfy its obligations under, any provision
of the Indenture (including, without limitation, the provisions of Section 1 of
Article VII of the Indenture).


 


The bonds of Series No. 19 are intended to be used as
collateral for and to secure payment of the Revenue Bonds, as hereinabove
provided, and, accordingly, the bonds of Series 


 


10





















 


No. 19 shall be dated as of the date of issuance of
the Revenue Bonds and shall bear interest from the Initial Interest Accrual
Date, as hereinabove provided, notwithstanding anything to the contrary
contained in the Indenture with respect to the dating of bonds and the date
from which interest on bonds shall accrue.


 


ARTICLE IV.


 


Section 1.  Capitalized terms used in this Article IV and
not otherwise defined in this Indenture shall have the meanings set forth in
the County Indenture.


 


Section 2.  Subsequent to the issuance of the Revenue
Bonds, the Company shall not be required to establish compliance with the net
earnings requirements of Section 5 of Article II of the Indenture in connection
with any Conversion of Interest Rate Mode on the Revenue Bonds or any change in
length of Long Term Rate Period.  So long
as the Revenue Bonds operate in any Interest Rate Mode other than the Long Term
Rate where the Long Term Rate Period ends on the day prior to the final
maturity of the Revenue Bonds, the Company shall include, for purposes of any
required calculation of such net earnings requirement (as such requirement
shall then be in effect), interest on the bonds of said Series at an annual
rate of 14%.  If at any time the interest
rate on the Revenue Bonds is a Long Term Rate where the Long Term Rate Period
ends on the day prior to the final maturity of the Revenue Bonds, the Company
may include, for purposes of any calculation of such net earnings requirement,
interest on the bonds of said Series at the Long Term Rate then borne by the
Revenue Bonds.


 


ARTICLE V.


 


Section 1.  The provisions of this supplemental indenture
shall be effective from and after the execution hereof; and the Indenture, as
hereby modified and amended, shall remain in full force and effect.


 


Section 2.  Each holder or registered owner of a bond of
any series not now outstanding which shall be authenticated by the Trustee and
issued by the Company under the Indenture (as hereby amended) subsequent to the
execution of this supplemental indenture and of any coupon pertaining to any
such bond, by the acquisition, holding or ownership of such bond and coupon,
thereby consents and agrees to, and shall be bound by, the provisions of this
supplemental indenture.


 


Section 3.  Each reference in the Indenture, or in this
supplemental indenture, to any article, section, term or provision of the
Indenture shall mean and be deemed to refer to such article, section, term or
provision of the Indenture, as hereby modified and amended, except where the
context otherwise indicates.


 


Section 4.  All the covenants, provisions, stipulations
and agreements in this supplemental indenture contained are and shall be for
the sole and exclusive benefit of the parties hereto, their successors and
assigns, and of the holders and registered owners from time to time of the
bonds and of the coupons issued and outstanding from time to time under and
secured by the Indenture, as hereby modified and amended.
