                (Form of reverse side of bond of Series No. 10)

  This bond is one of the bonds of the Company issued and to be issued from
time to time under and in accordance with and all secured by the indenture of
mortgage or deed of trust dated May 1, 1947, executed and delivered by the
Company to Bank of America 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, 1994, executed
and delivered by the Company to said Bank of America Illinois and Robert J.
Donahue (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 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.
10 (hereinafter called the "bonds of Series No. 10" or the "bonds of said
Series"). The bonds of Series No. 10 have been issued to Bank One, Lexington,
N.A., Lexington, Kentucky, as trustee (said trustee or any successor trustee
being hereinafter referred to as the "County Trustee") under the Indenture of
Trust dated as of November 1, 1994 (the "County Indenture"), between the County
and the County Trustee, to secure payment of the Collateralized Solid Waste
Disposal Facilities Revenue Bonds (Kentucky Utilities Company Project) 1994
Series A (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 November 1, 1994 (the "Agreement"), between the Company and the
County.

  Except as provided in the next succeeding paragraph, upon an event of default
under Section 9.1 of the Agreement or an event of default under Section 9.01(a)
or (b) of the County Indenture, the bonds of Series No. 10 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 or dates 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 said Series. The Trustee shall, within 10 days after receiving
such Redemption Demand, mail a copy thereof by certified mail 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 said Series so demanded to be
redeemed (hereinafter called the "Demand Redemption Date"). Notice of the date
fixed as 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 the Demand Redemption Date may be any date up to and
including the earlier of (x) the 120th day after receipt by the Trustee of the
Redemption Demand or (y) November 1, 2024; 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 (x) the 120th day after receipt by the Trustee
of the Redemption Demand or (y) November 1, 2024. The Trustee shall mail notice
of the Demand Redemption Date (such notice being hereinafter called

                                     -54-


the "Demand Redemption Notice") to the County Trustee not more than 10 or less
than five days prior to the Demand Redemption Date. Notwithstanding the
foregoing, if any of the events of default described in the first sentence of
this paragraph is existing on November 1, 2024, 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. 10 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 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 said Series 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 effect any subsequent default or impair any right consequent
thereon.

  In the event that all the bonds outstanding under the Indenture shall, if not
already due, have become immediately due and payable, whether by declaration or
otherwise, and such acceleration shall not have been annulled, the bonds of
Series No. 10 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 pursuant to Article II, Section 2 of the supplemental indenture dated as
of November 1, 1994 referred to above 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, or upon provision for the payment thereof having been made in
accordance with Article VIII of the County Indenture, bonds of Series No. 10 in
a principal amount equal to the principal amount of the Revenue Bonds so
surrendered and cancelled shall be surrendered by the County Trustee to the
Trustee whereupon the bonds of said Series so surrendered shall be deemed fully
paid and the obligations of the Company thereunder shall be terminated, and
such bonds of said Series 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 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.

  AND WHEREAS, there is to be endorsed on each of the bonds of Series No. 10
(whether in temporary or definitive form) a certificate of the Trustee
substantially in the following form, to-wit:

                                     -55-
