The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on this Debenture is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Debenture (or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the regular record date for such interest installment, which, subject to the following sentence, shall be the close of business on the business day next preceding such Interest Payment Date. If pursuant to Section 305 of the Indenture this series of Debentures is no longer represented by a Global Security, the Company may select a regular record date for such interest installment which shall be any date at least one Business Day before an Interest Payment Date.

The principal of and the interest on this Debenture shall be payable at the office or agency of the Trustee maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at such address as shall appear in the Security Register. The indebtedness evidenced by this Debenture is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, as defined in the Indenture, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions. The indebtedness evidenced by this Debenture is entitled to the benefits of a Support Agreement, dated as of April 4, 1989, as amended as of May 15, 1989, December 10, 1990, and February 14, 1991 (as such Agreement may be hereafter amended, modified or supplemented from time to time in accordance with the terms and conditions of the Indenture, the "Support Agreement") between the Company and NIPSCO Industries, Inc.

The Support Agreement also provides that any Lender to the Company shall have the right to demand that the Company enforce its rights against Industries under the Support Agreement as described in the previous sentence, and in the event that the Company fails to require Industries to perform -2- such obligations or the Company defaults in the timely payment of principal of or any premium or interest on any Debt owed to a Lender, such Lender may proceed directly against Industries to enforce the Company's rights against Industries under the Support Agreement or to obtain payment of such defaulted principal, premium or interest owed to such Lender. The Support Agreement provides that in no event may any Lender, on default of the Company or Industries or upon failure by the Company or Industries to comply with the Support Agreement, have recourse to or against the stock or assets of Northern Indiana Public Service Company ("Northern Indiana") or any interest of the Company or Industries therein. Notwithstanding this limitation, the Support Agreement provides that funds available to Industries to satisfy any obligations under the Support Agreement will include cash dividends paid by Northern Indiana to Industries.

The Support Agreement may be amended or terminated at any time by the agreement of Industries and the Company, provided that (i) no amendment regarding the terms described above may be made unless all Lenders consent in advance and in writing to such amendment, (ii) no amendment regarding any other term of the Support Agreement may be made in a manner that adversely affects the rights of Lenders unless all affected Lenders consent in advance and in writing to such amendment, and (iii) no termination shall be effective until such time as all Debt (including the Debentures) shall have been paid in full. This Debenture shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee. Unless the Certificate of Authentication hereon has been executed by the Trustee referred to on the reverse side hereof, this Debenture shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. The provisions of this Debenture are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place. -3- IN WITNESS WHEREOF, the Company has caused this instrument to be executed.

Any redemption pursuant to this paragraph will be made upon not less than 30 nor more than 60 days' notice at the Optional Redemption Price. If the Debentures are only partially redeemed by the Company pursuant to an Optional Redemption, the Debentures will be redeemed pro rata or by lot or by any other method utilized by the Trustee; provided that if, at the time of redemption, the Debentures are registered as a Global Security, the Depositary shall determine by lot the principal amount of such Debentures held by each Debentureholder to be redeemed. In the event of redemption of this Debenture in part only, a new Debenture or Debentures of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

Before the termination of any such Extended Interest Payment Period, the Company may further extend such Extended Interest Payment Period, provided that such Extended Interest Payment Period, together with all previous and further extensions thereof, shall not exceed 20 consecutive quarters or extend beyond the maturity of the Debentures. At the termination of any such Extended Interest Payment Period and upon the payment of all accrued and unpaid interest and any additional amounts then due, the Company may commence a new Extended Interest Payment Period.
