                     amortization, improvement or analogous fund, established in accordance
                     with the provisions of the Indenture hereinafter mentioned, may afford
                     additional security for the bonds of any particular series and except as
                     provided in Section 3 of Article VI of said Indenture) by an Indenture,
                     dated as of October 1, 1924, duly executed by the Company to Bankers Trust
                     Company, a corporation of the State of New York, as Trustee, to which
                     Indenture and all indentures supplemental thereto (including the
                     Supplemental Indenture dated as of July 15, 1989) reference is hereby made
                     for a description of the properties and franchises mortgaged and conveyed,
                     the nature and extent of the security, the terms and conditions upon which
                     the bonds are issued and under which additional bonds may be issued, and
                     the rights of the holders of the bonds and of the Trustee in respect of
                     such security (which Indenture and all indentures supplemental thereto,
                     including the Supplemental Indenture dated as of July 15, 1989, are
                     hereinafter collectively called the "Indenture"). As provided in the
                     Indenture, said bonds may be for various principal sums and are issuable
                     in series, which may mature at different times, may bear interest at
                     different rates and may otherwise vary as in said Indenture provided. With
                     the consent of the Company and to the extent permitted by and as provided
                     in the Indenture, the rights and obligations of the Company and of the
                     holders of the bonds and the terms and provisions of the Indenture, or of
                     any indenture supplemental thereto, may be modified or altered in certain
                     respects by affirmative vote of at least eighty-five percent (85%) in
                     amount of the bonds then outstanding, and, if the rights of one or more,
                     but less than all, series of bonds then outstanding are to be affected by
                     the action proposed to be taken, then also by affirmative vote of at least
                     eighty-five percent (85%) in amount of the series of bonds so to be
                     affected (excluding in every instance bonds disqualified from voting by
                     reason of the Company's interest therein as specified in the Indenture);
                     provided, however, that, without the consent of the holder hereof, no such
                     modification or alteration shall, among other things, affect the terms of
                     payment of the principal of or the interest on this bond, which in those
                     respects is unconditional.

                       The holders of the bonds of Series KKP No. 10, by their acceptance of
                     and holding thereof, consent and agree that bonds of any series may be
                     issued which mature on a date or dates later than October 1, 2024 and also
                     consent to the deletion from the first paragraph of Section 5 of Article
                     II of the Indenture of the phrase "but in no event later than October 1,
                     2024,". Such holders further agree that (a) such consent shall, for all
                     purposes of Article XV of the Indenture and without further action on the
                     part of such holders, be deemed the affirmative vote of such holders at
                     any meeting called pursuant to said Article XV for the purpose of
                     approving such deletion, and (b) such deletion shall become effective at
                     such time as not less than eighty-five per cent (85%) in principal amount
                     of bonds outstanding under the Indenture shall have consented thereto
                     substantially in the manner set forth in Section 4 of Part I of the
                     Supplemental Indenture dated as of July 15, 1989, or in writing, or by
                     affirmative vote cast at a meeting called pursuant to said Article XV, or
                     by any combination thereof.

                       This bond is redeemable upon the terms and conditions set forth in the
                     Indenture, including provision for redemption upon demand of the Monroe
                     Trust Indenture Trustee following the occurrence of an Event of Default
                     under the Monroe Trust Indenture and the acceleration of the principal of
                     the Monroe Revenue Bonds.
 
                       Under the Indenture, funds may be deposited with the Trustee (which
                     shall have become available for payment), in advance of the redemption
                     date of any of the bonds of Series KKP No. 10 (or portions thereof), in
                     trust for the redemption of such bonds (or portions thereof) and the
                     interest due or to become due thereon, and thereupon all obligations of
                     the Company in respect of such bonds (or portions thereof) so to be
                     redeemed and such interest shall cease and be discharged, and the holders
                     thereof shall thereafter be restricted exclusively to such funds for any
                     and all claims of whatsoever nature on their part under the Indenture or
                     with respect to such bonds (or portions thereof) and interest.
 
                       In case an event of default, as defined in the Indenture, shall occur,
                     the principal of all the bonds issued thereunder may become or be declared
                     due and payable, in the manner, with the effect and subject to the
                     conditions provided in the Indenture.
 
                       Upon payment of the principal of, or premium, if any, or interest on,
                     the Monroe Revenue Bonds, whether at maturity or prior to maturity by
                     redemption or otherwise or upon provision for the payment thereof having
                     been made in accordance with Article IX of the Monroe Trust Indenture,
                     bonds of Series KKP No. 10 in a principal amount equal to the principal
                     amount of such Monroe Revenue Bonds and having both a corresponding
                     maturity date and interest rate shall, to the extent of such payment of
                     principal, premium or interest, be deemed fully paid and the obligation of
                     the Company thereunder to make such payment shall forthwith cease and be
                     discharged, and, in the case of the payment of principal and premium, if
                     any, such bonds of said series shall be surrendered for cancellation or
                     presented for appropriate notation to the Trustee.
 
                       This bond is not assignable or transferable except as may be required to
                     effect a transfer to any successor trustee under the Monroe Trust
                     Indenture, or, subject to compliance with applicable law, as may be
                     involved in the course of the exercise of rights and remedies consequent
                     upon an Event of Default under the Monroe Trust Indenture. Any such
                     transfer shall be made by the registered holder hereof, in person or by
                     his attorney duly authorized in writing, on the books of the Company kept
                     at its office or agency in the Borough of Manhattan, The City and State of
                     New York, upon surrender and cancellation of this bond, and thereupon, a
                     new registered bond of the same series of authorized denominations for a
                     like aggregate principal amount will be issued to the transferee in
                     exchange therefor, and this bond with others in like form may in like
                     manner be exchanged for one or more new bonds of the same series of other
                     authorized denominations, but of the same aggregate principal amount, all
                     as provided and upon the terms and conditions set forth in the Indenture,
                     and upon payment, in any event, of the charges prescribed in the
                     Indenture.

                       No recourse shall be had for the payment of the principal of or the
                     interest on this bond, or for any claim based hereon or otherwise in
                     respect hereof or of the Indenture, or of any indenture supplemental
                     thereto, against any incorporator, or against any past, present or future
                     stockholder, director or officer, as such, of the Company, or of any
                     predecessor or successor corporation, either directly or through the
                     Company or any such predecessor or successor corporation, whether for
                     amounts unpaid on stock subscriptions or by virtue of any constitution,
                     statute or rule of law, or by the enforcement of any assessment or penalty
                     or otherwise howsoever; all such liability being, by the acceptance hereof
                     and as part of the consideration for the issue hereof, expressly waived
                     and released by every holder or owner hereof, as more fully provided in
                     the Indenture.
