Pursuant to the terms of the Indenture, the Company desires to provide for the establishment of a new series of its Securities to be known as its 8 3/8% Junior Subordinated Deferrable Interest Debentures, Series A, Due June 30, 2044 (herein called the "QUIDS"), the form and substance of such QUIDS and the terms, provisions and conditions thereof to be set forth as provided in the Indenture and this First Supplemental Indenture. All things necessary to make this First Supplemental Indenture a valid agreement of the Company, and to make the QUIDS, when executed by the Company and authenticated and delivered by the Trustee, the valid obligations of the Company, have been done. NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH: For and in consideration of the premises and the purchase of the QUIDS by the holders thereof, and for the purpose of setting forth, as provided in the Indenture, the form and substance of the QUIDS and the terms, provisions and conditions thereof, it is mutually agreed, for the equal and proportionate benefit of all holders of the QUIDS, as follows: ARTICLE ONE GENERAL TERMS AND CONDITIONS OF THE QUIDS SECTION 101. There shall be and is hereby authorized a series of Securities designated the "8 3/8% Junior Subordinated Deferrable Interest Debentures, Series A, Due June 30, 2044" (the "QUIDS"), limited in aggregate principal amount to $100,000,000, which amount shall be as set forth in any written order of the Company for the authentication and delivery of the QUIDS. The QUIDS shall mature and the principal shall be due and payable together with all accrued and unpaid interest thereon on June 30, 2044, and shall be issued in the form of registered QUIDS without coupons, as set forth in Article Four hereof. SECTION 102. Except as provided in Section 104 herein, the QUIDS shall be issued in certificated form. Principal of and interest (and to the extent legally enforceable, interest on any overdue principal and on any overdue installment of interest) on the QUIDS issued in certificated form will be payable, the transfer of such QUIDS will be registrable and such QUIDS will be exchangeable for the QUIDS bearing identical terms and provisions at the office or agency of the Company in the Borough of Manhattan, The City and State of New York; PROVIDED, HOWEVER, that payment of interest may be made at the option of the Company by check mailed to the registered holder entitled thereto at such address as shall appear in the security register. SECTION 103. Each QUIDS will bear interest at the rate of 8 3/8% per annum from the original date of issuance until the principal thereof becomes due and payable, and on any overdue principal and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum, payable quarterly on March 31, June 30, September 30, and December 31 (each, an "Interest Payment Date"), commencing on June 30, 1995, to the person in whose name such QUIDS or any predecessor QUIDS is registered, at the close of business on the Business Day next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the holders on such regular record date, and may be paid to the registered holder in whose name the QUIDS (or one or more predecessor Securities) is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the holders of the QUIDS not less than 10 days prior to such special record date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any Securities exchange on which the QUIDS may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. Interest will accrue from the date of original issuance to, but not including, the relevant payment date. In the event that any date on which interest is payable on the QUIDS is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which 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. A "Business Day" means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York and any other Place of Payment are authorized or obligated by law to close. SECTION 104. The QUIDS shall be issuable in the form of one or more Global Securities. The Depositary for the QUIDS shall be The Depository Trust Company. SECTION 105.

ARTICLE THREE EXTENSION OF INTEREST PAYMENT PERIOD SECTION 301. The Company shall have the right, at any time during the term of the QUIDS, from time to time to extend the interest payment period of such QUIDS for up to 20 consecutive quarters (the "Extension Period"), at the end of which period the Company shall pay all interest accrued and unpaid thereon together with interest thereon at the rate specified for the QUIDS; PROVIDED that, during such Extension Period, the Company shall not declare or pay any dividend on, or redeem, purchase, acquire or make a liquidation payment or make any guarantee payment with respect to, any of its capital stock. Prior to the termination of any such Extension Period, the Company may further extend such Extension Period. Any Extension Period together, if extended, with all such previous and further extensions thereof, (i) shall terminate on an Interest Payment Date and (ii) shall not exceed 20 consecutive quarters or extend beyond the stated maturity of the QUIDS. Upon the termination of any Extension Period and upon the payment of all accrued and unpaid interest then due, the Company may select a new Extension Period, subject to the foregoing requirements. No interest during an Extension Period, except at the end thereof, shall be due and payable. SECTION 302. (a) The Company shall give the holders of the QUIDS and the Trustee written notice of its selection of such Extension Period not less than 10 Business Days prior to the earlier of (i) the next succeeding Interest Payment Date or (ii) the date the Company is required to give notice to holders of the QUIDS (or, if applicable, to the American Stock Exchange or other applicable self-regulatory organization) of the record or payment date of such interest payment, but in any event not less than two business days prior to such record date. (b) The quarter in which any notice is given pursuant to paragraph (a) of this Section shall constitute one of the 20 quarters which comprise the maximum Extension Period.
