Notwithstanding the foregoing, so long as the Holder of any Debentures is the Property Trustee, the payment of the principal of and interest (including Compounded Interest, if any) on such Debentures held by the Property Trustee will be made by wire transfer of immediately available funds at such place and to such account as may be designated by the Property Trustee. Payment of principal of the Debentures will only be made upon surrender of the Debentures to the Trustee. The Debentures will be denominated in Dollars and payment of principal and interest on the Debentures shall be made in Dollars. SECTION 2.4 GLOBAL DEBENTURE. ---------------- (a) In connection with a distribution of the Debentures to the holders of the Trust Securities pursuant to the Declaration: (i) The Debentures in certificated form may be presented to the Trustee by the Property Trustee in exchange for a global Debenture in an aggregate principal amount equal to the aggregate principal amount of all Outstanding Debentures of such series (a "Global Debenture"), to be registered in the name of the Depository, or its nominee, and delivered by the Trustee to the 6 Depository for crediting to the accounts of its participants pursuant to the instructions of the Regular Trustees. The Issuer upon any such presentation shall execute a Global Debenture in such aggregate principal amount and deliver the same to the Trustee for authentication and delivery in accordance with the Indenture and this First Supplemental Indenture. Payments on the Debentures issued as a Global Debenture will be made to the Depository. (ii) If any Preferred Securities are held in non book-entry certificated form, the Debentures in certificated form may be presented to the Trustee by the Property Trustee and any Preferred Security Certificate which represents Preferred Securities other than Preferred Securities held by the Depository or its nominee ("Non Book-Entry Preferred Securities") will be deemed to represent beneficial interests in Debentures presented to the Trustee by the Property Trustee having an aggregate principal amount equal to the aggregate liquidation amount of the Non Book-Entry Preferred Securities until such Preferred Security Certificates are presented to the Registrar for transfer or reissuance at which time such Preferred Security Certificates will be canceled and a Debenture, registered in the name of the holder of the Preferred Security Certificate or the transferee of the holder of such Preferred Security Certificate, as the case may be, with an aggregate principal amount equal to the aggregate liquidation amount of the Preferred Security Certificate canceled, will be executed by the Issuer and delivered to the Trustee for authentication and delivery in accordance with the Indenture and this First Supplemental Indenture. On issue of such Debentures, Debentures with an equivalent aggregate principal amount that were presented by the Property Trustee to the Trustee will be deemed to have been canceled. (b) Unless and until it is exchanged for Debentures in registered certificated form, a Global Debenture may be transferred, in whole but not in part, only by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository selected or approved by the Issuer or a nominee of such successor Depository. (c) If at any time the Depository for the Debentures notifies the Issuer that it is unwilling or unable to continue as Depository for the Debentures or if at any time the Depository for the Debentures shall no longer be registered or in good standing as a clearing agency under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, at a time at which the Depository is required to be so registered to act as Depository for the Debentures, and a successor Depository for such series is not appointed by the Issuer within 90 days after the Issuer receives such notice or becomes aware of such condition, as the case may be, the Issuer will execute, and, subject to Article 3 of the Indenture, the Trustee, upon written notice from the Issuer, will authenticate and deliver the Debentures in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Debenture in exchange for such Global Debenture. In addition, the Issuer, in its sole discretion, may at any 7 time determine that the Debentures shall no longer be represented by a Global Debenture. In such event the Issuer will execute, and subject to Article 3 of the Indenture, the Trustee, upon receipt of an Officers' Certificate evidencing such determination by the Issuer, will authenticate and deliver the Debentures in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the Global Debenture in exchange for such Global Debenture. Upon the exchange of the Global Debenture for such Debentures in definitive registered form without coupons, in authorized denominations, the Global Debenture shall be canceled by the Trustee. Such Debentures in definitive registered form issued in exchange for the Global Debenture shall be registered in such names and in such authorized denominations as the Depository, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such registered certificated Debentures in definitive form in exchange for the Global Debenture to the Depository for delivery to the Persons in whose names such Debentures are so registered. SECTION 2.5 INTEREST. -------- (a) The Debentures will bear interest at the fixed rate of 6.68% per annum (the "Coupon Rate") from the original date of issuance or from the most recent Interest Payment Date to which interest has been paid or duly provided for 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 Coupon Rate, compounded quarterly, payable (subject to the provisions of Article IV) quarterly in arrears on March 31, June 30, September 30 and December 31 of each year (each, an "Interest Payment Date"), commencing on March 31, 1999. Interest on the Debentures (except defaulted interest) shall be paid to the Persons in whose name the Debentures are registered, at the close of business on the regular Record Date for such interest installment (including Debentures that are canceled after the Record Date and before the Interest Payment Date), which, with respect to any Debentures of which the Property Trustee is the Holder or with respect to a Global Debenture, shall be the close of business on the Business Day next preceding that Interest Payment Date. Notwithstanding the foregoing sentence, if the Preferred Securities are no longer in book-entry only form or if, pursuant to the Indenture and this First Supplemental Indenture the Debentures are distributed to the holders of the Trust Securities and are not represented by a Global Debenture, the Issuer may select a regular Record Date for such interest installment which shall conform to the rules of any securities exchange, interdealer quotation system or other organization on which the Debentures are listed and which shall be more than ten Business Days but less than 60 Business Days before the applicable Interest Payment Date. Notwithstanding the foregoing, any interest that is payable at maturity shall be payable to the Person to whom principal payable at maturity shall be payable. (b) The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full quarter on the basis of the actual number of days elapsed in such 90-day quarter. In the event that any date on which interest is payable on the Debentures is not a Business Day, then payment of 8 the 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, notwithstanding any provision of the Indenture to the contrary, 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. (c) If, at any time while the Property Trustee is the Holder of any Debentures, the Trust or the Property Trustee is required to pay any taxes, duties, assessment or governmental charges of whatever nature (other than withholding taxes) imposed by the United States, or any other taxing authority, then, in any case, the Company will pay as additional interest ("Additional Interest") on the Debentures held by the Property Trustee, such additional amounts as shall be required so that the net amounts received and retained by the Trust and the Property Trustee after paying such taxes, duties, assessments or other governmental charges will be equal to the amounts the Trust and the Property Trustee would have received had no such taxes, duties, assessments or other government charges been imposed. SECTION 2.6 AUTHORIZED DENOMINATIONS. The Debentures shall be issuable in ------------------------ denominations of $25 and integral multiples of $25 in excess thereof. SECTION 2.7 REDEMPTION.

The Depository Trust Company (or its nominee) ---------- shall act as the initial Depository for any Global Debenture which may be issued pursuant to this First Supplemental Indenture. ARTICLE III REDEMPTION OF THE DEBENTURES ---------------------------- SECTION 3.1 Special Event Redemption. If a Special Event has occurred and ------------------------ is continuing then, notwithstanding Section 3.2 hereof but subject to the provisions of Article XI of the Indenture, the Issuer shall have the right, upon not less than 30 days' nor more than 60 days' notice to the Holders of the Debentures, to redeem the Debentures, in whole or in part, for cash within 90 9 days following the occurrence of such Special Event at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon (including Compounded Interest, if any) to the date of such redemption (the "Redemption Price"). The Redemption Price shall be paid prior to 12:00 noon, New York time, on the date of such redemption or at such earlier time as the Issuer determines and specifies in the notice of redemption, provided the Issuer shall deposit with the Trustee an amount sufficient to pay the Redemption Price at least one hour prior to the time such Redemption Price is to be paid. SECTION 3.2 OPTIONAL REDEMPTION. Subject to the provisions of Section 3.3 ------------------- hereof and Article 11 of the Indenture, the Issuer shall have the right to redeem the Debentures, in whole or in part, at any time or from time to time, on or after February 3, 2004, at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon, (including Compounded Interest, if any), to the date of such redemption (the "Optional Redemption Price"). Any redemption pursuant to this paragraph will be made upon not less than 30 days nor more than 60 days notice to the Holder of the Debentures, at the Optional Redemption Price. The Optional Redemption Price shall be paid prior to 12:00 noon, New York time, on the date of such redemption or at such earlier time as the Issuer determines and specifies in the notice of redemption, provided that the Issuer shall deposit with the Trustee an amount sufficient to pay the Optional Redemption Price at least one hour prior to the time such Optional Redemption Price is to be paid. SECTION 3.3 PARTIAL REDEMPTION. ------------------ (a) If a partial redemption of the Debentures would result in the delisting of the Preferred Securities issued by the Trust from any national securities exchange, interdealer quotation system or other organization on which the Preferred Securities are then listed, the Issuer shall not be permitted to effect such partial redemption and may only redeem the Debentures in whole. (b) The Issuer may not redeem fewer than all of the Outstanding Debentures unless all accrued and unpaid interest on the Debentures has been paid as of the Interest Payment Date next preceding the Redemption Date. (c) If the Debentures are only partially redeemed pursuant to Section 3.2, 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 Debenture, the Depository shall determine, in accordance with its procedures, the principal amount of such Debentures credited to each of its participant accounts to be redeemed. 10 ARTICLE IV EXTENSION OF INTEREST PAYMENT PERIOD ------------------------------------ SECTION 4.1 EXTENSION OF INTEREST PAYMENT PERIOD. The Issuer shall have ------------------------------------ the right, at any time and from time to time during the term of the Debentures, to defer payments of interest on the Debentures by extending the interest payment period of the Debentures for a period not exceeding 20 consecutive quarters (the "Extended Interest Payment Period"), during which Extended Interest Payment Period no interest shall be due and payable; provided that no Extended Interest Payment Period may extend beyond the Maturity Date. To the extent permitted by applicable law, interest, the payment of which has been deferred because of the extension of the interest payment period pursuant to this Section 4.1, will bear interest thereon at the Coupon Rate compounded quarterly for each quarter of the Extended Interest Payment Period ("Compounded Interest"). At the end of the Extended Interest Payment Period, the Issuer shall pay all interest accrued and unpaid on the Debentures, including any Compounded Interest (all such interest the "Deferred Interest") that shall be payable to the Holders of the Debentures in whose names the Subordinated Debentures are registered in the Register as of the Record Date relating to the Interest Payment Date that corresponds to the end of such Extended Interest Payment Period. Before the termination of any Extended Interest Payment Period, the Issuer may further extend such period, provided that such period together with all such previous and further extensions thereof shall not exceed 20 consecutive quarters or extend beyond the Maturity Date. Upon the termination of any Extended Interest Payment Period and upon the payment of all Deferred Interest then due, the Issuer may commence a new Extended Interest Payment Period, subject to the foregoing requirements. No interest shall be due and payable during an Extended Interest Payment Period, except at the end thereof, but the Issuer may prepay at any time all or any portion of the Deferred Interest accrued during an Extended Interest Payment Period. SECTION 4.2 NOTICE OF EXTENSION. ------------------- (a) If the Property Trustee is the only registered Holder of the Debentures at the time the Issuer selects an Extended Interest Payment Period, the Issuer shall give written notice to the Trustee, the Regular Trustees and the Property Trustee of its selection of such Extended Interest Payment Period one Business Day before the earlier of (i) the next succeeding date on which Distributions on the Trust Securities are payable, or (ii) the date the Regular Trustees, on behalf of the Trust, are required to give notice of the record date, or the date such Distributions are payable, to holders of the Preferred Securities (or any national securities exchange or self-regulatory organization on which the Preferred Securities are listed). (b) If the Property Trustee is not the only Holder of the Debentures at the time the Issuer selects an Extended Interest Payment Period, the Issuer shall give the Trustee, the Property Trustee and the Holders of the Debentures written notice of its selection of such Extended Interest Payment Period 10 Business Days before the earlier of (i) the next succeeding Interest Payment Date, or (ii) the date the Issuer is required to give notice of the 11 record or payment date of such interest payment to the New York Stock Exchange or other applicable self-regulatory organization or to Holders of the Debentures. (c) The quarter in which any notice is given pursuant to paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the 20 quarters permitted in the maximum Extended Interest Payment Period permitted under Section 4.1. SECTION 4.3 LIMITATION OF TRANSACTIONS.
