The Company shall have the right at any time during the term of the Securities to defer interest payments from time to time by extending the interest payment period for successive periods (each, an "Extension Period") not exceeding 20 consecutive quarters for each such period; PROVIDED, no Extension Period may extend beyond the maturity date of the Securities. At the end of each Extension Period, the Company shall be responsible for the payment of, and the Company shall pay all interest then accrued and unpaid (including Additional Interest and Liquidated Damages) together with interest thereon compounded quarterly at the rate specified for the Securities to the extent permitted by applicable law ("Compounded Interest"); PROVIDED, that during any Extension Period, the Company shall not, and shall not allow any of its Subsidiaries (other than, with respect to clause (i) below only, its wholly owned Subsidiaries) to, (i) declare or pay dividends on, make distributions with respect to, or redeem, purchase or acquire, or make a liquidation payment with respect to, any of its capital stock (except for (1) dividends or distributions in shares of Common Stock on Common Stock or on the Preferred Stock, (2) purchases or acquisitions of shares of Common Stock made in connection with any employee benefit plan of the Company or its subsidiaries in the ordinary course of business or pursuant to employment agreements with officers or employees of the Company or its subsidiaries entered into in the ordinary course of business, provided that such repurchases by the Company made from officers or employees of the Company or its subsidiaries pursuant to employment agreements shall be made at a price not to exceed market value on the date of any such repurchase and shall not exceed $1 million in the aggregate for all such employees and officers, (3) conversions or exchanges of shares of Common Stock of any one class into shares of Common Stock of another class or (4) purchases of fractional interests in shares of the Company's capital stock pursuant to the conversion or exchange provisions of any of the Company's securities being converted or exchanged), (ii) make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem, any debt securities issued by the Company that rank junior to or PARI PASSU with the Securities and (iii) make any guarantee payments with respect to the foregoing.

Upon the termination of any Extension Period and the payment of all amounts then due, the Company may commence a new Extension Period, subject to the above requirements. No interest during an Extension Period, except at the end thereof, shall be due and payable. If the Property Trustee is the sole holder of the Securities at the time the Company selects an Extension Period, the Company shall give notice to the Regular Trustees, the Property Trustee and the Trustee of its selection of such Extension Period at least one Business Day prior to the earlier of (i) the date the distributions on the Preferred Securities are payable or (ii) if the Preferred Securities are listed on the New York Stock Exchange, Inc. ("NYSE") or other stock exchange or quotation system, the date the Trust is required to give notice to the NYSE or other applicable self-regulatory organization or to holders of the Preferred Securities on the record date or the date such distributions are payable, but in any event not less than ten Business Days prior to such record date. -5- If the Property Trustee is not the sole holder of the Securities at the time the Company selects an Extension Period, the Company shall give the Holders and the Trustee notice of its selection of an Extension Period at least ten Business Days prior to the earlier of (i) the next succeeding Interest Payment Date or (ii) if the Preferred Securities are listed on the NYSE or other stock exchange or quotation system, the date the Company is required to give notice to NYSE or other applicable self-regulatory organization or to holders of the Securities on the record or payment date of such related interest payment, but in any event not less than two Business Days prior to such record date.

Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

The Company issued the Securities under an indenture, dated as of October 2, 1996 (the "Indenture"), between the Company and Wilmington Trust Company, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Trustee, the Company and the Holders, and of the terms upon which the Securities are, and are to be, authenticated and delivered. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) ("TIA") as in effect on the date of the Indenture. The Securities are subject to, and qualified by, all such terms, certain of which are summarized hereon, and Holders are referred to the Indenture and the TIA for a statement of such terms. The Securities are unsecured general obligations of the Company limited to $180,412,350 in aggregate principal amount (or $207,474,200 if the overallotment option is exercised). No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. (vii) OPTIONAL REDEMPTION.

On or after the Redemption Date, interest will cease to accrue on the Securities, or portion thereof, called for redemption. (viii) OPTIONAL REDEMPTION UPON TAX EVENT. The Securities are subject to redemption in whole (but not in part), at any time within 90 days thereafter, if a Tax Event (as defined in the Declaration) shall occur and be continuing, at the applicable redemption price set forth above (or, for the period commencing on the date of issuance of the Securities through October 4, 1997 and the twelve month periods commencing October 5, 1997 and October 5, 1998, the product of 106.750%, 106.075% and 105.400%, respectively, times $50), in each case -7- plus accrued but unpaid interest, including Additional Interest, Compounded Interest and Liquidated Damages, if any, to the Redemption Date. Any redemption pursuant to this Section 8 will be made upon not less than 30 nor more than 60 days' notice. (ix) NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Securities to be redeemed at his address of record. The Securities in denominations larger than $50 may be redeemed in part but only in integral multiples of $50. In the event of a redemption of less than all of the Securities, the Securities will be chosen for redemption by the Trustee in accordance with the Indenture. On and after the Redemption Date, interest ceases to accrue on the Securities or portions of them called for redemption. If this Security is redeemed subsequent to a Regular Record Date with respect to any Interest Payment Date specified above and on or prior to such Interest Payment Date, then any accrued interest will be paid to the person in whose name this Security is registered at the close of business on such record date. (x) REDEMPTION. The Securities will mature on October 1, 2016, and may be redeemed, in whole or in part, at any time after October 5, 1999 as set forth above or at any time in certain circumstances upon the occurrence of a Tax Event as set forth above. Upon the repayment of the Securities, whether at maturity or upon redemption, the proceeds from such repayment or payment shall simultaneously be applied to redeem Trust Securities having an aggregate liquidation amount equal to the Securities so repaid or redeemed at the applicable redemption price together with accrued and unpaid distributions through the date of redemption; PROVIDED, that holders of the Trust Securities shall be given not less than 30 nor more than 60 days notice of such redemption. Upon the repayment of the Securities at maturity or upon any acceleration, earlier redemption or otherwise, the proceeds from such repayment will be applied to redeem the Preferred Securities, in whole, upon not less than 30 nor more than 60 days' notice. There are no sinking fund payments with respect to the Securities. (xi) CONVERSION. The Holder of any Security has the right, exercisable at any time prior to the close of business (New York time) on the Business Day immediately preceding the date of repayment of such Security whether at maturity or upon redemption (either at the option of the Company or pursuant to a Tax Event), to convert the principal amount thereof (or any portion thereof that is an integral multiple of $50) into the number of shares of Common Stock obtained by dividing $50 per Security by the applicable conversion price (initially $28.75 per share of Common Stock for each Security) (equivalent to a conversion rate of 1.739 shares per share of Common Stock of the Company per Security), subject to adjustment under certain circumstances as set forth in the Indenture. To convert a Security, a Holder must (1) complete and sign a conversion notice substantially in the form attached hereto, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements or transfer documents if required by the Security Registrar or Conversion Agent and (4) pay any transfer or similar tax, if required. Upon conversion, no adjustment or payment will be made for interest or dividends, but if any Holder surrenders a Security for conversion after the close of business on the Regular Record Date for the payment of -8- an installment of interest and prior to the opening of business on the next Interest Payment Date, then, notwithstanding such conversion, the interest payable on such Interest Payment Date will be paid to the registered Holder of such Security on such Regular Record Date. In such event, such Security, when surrendered for conversion, need not be accompanied by payment of an amount equal to the interest payable on such Interest Payment Date on the portion so converted. The number of shares issuable upon conversion of a Security is determined by dividing the principal amount of the Security converted by the conversion price in effect on the Conversion Date. No fractional shares will be issued upon conversion but a cash adjustment will be made for any fractional interest. The Outstanding principal amount of any Security shall be reduced by the portion of the principal amount thereof converted into shares of Common Stock. (xii) REGISTRATION RIGHTS. The holders of the Preferred Securities, the Securities, the Guarantee and the shares of Common Stock of the Company issuable upon conversion of the Securities (collectively, the "REGISTRABLE SECURITIES") are entitled to the benefits of a Registration Rights Agreement, dated as of October 2, 1996, among the Company, the Trust and the Initial Purchasers (the "Registration Rights Agreement"). Pursuant to the Registration Rights Agreement, the Company has agreed for the benefit of the holders of Registrable Securities that (i) it will, at its cost, within 75 days after the date of issuance of the Registrable Securities, file a shelf registration statement (the "Shelf Registration Statement") with the Commission with respect to resales of the Registrable Securities, (ii) it will use its reasonable efforts to cause, such Shelf Registration Statement to be declared effective by the Commission within 135 days after the date of issuance of the Registrable Securities and (iii) the Company will use its reasonable efforts to maintain such Shelf Registration Statement continuously effective under the Securities Act until the third anniversary of the effectiveness of the Shelf Registration Statement or such earlier date as is provided in the Registration Rights Agreement. Reference is made to the Registration Rights Agreement for a description of, among other things, the circumstances under which a "Registration Default" may be declared if such Shelf Registration Statement is not filed or is not declared effective within a specified period of time, and additional interest "Liquidated Damages" may accrue and by payable on the Securities as a result of such a Registration Default. (xiii) REGISTRATION, TRANSFER, EXCHANGE AND DENOMINATIONS. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in New York, New York or Wilmington, Delaware, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. The Securities are issuable only in registered form without coupons in denominations of $50 and integral multiples thereof. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior -9- to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. In the event of redemption or conversion of this Security in part only, a new Security or Securities for the unredeemed or unconverted portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. (xiv) PERSONS DEEMED OWNERS. Except as provided in Section 4 hereof, the registered Holder of a Security may be treated as its owner for all purposes. (xv) UNCLAIMED MONEY. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent shall pay the money back to the Company at its written request. After that, holders of Securities entitled to the money must look to the Company for payment unless an abandoned property law designates another Person and all liability of the Trustee and such Paying Agent with respect to such money shall cease. (xvi) DEFAULTS AND REMEDIES. The Securities shall have the Events of Default as set forth in Section 501 of the Indenture. Subject to certain limitations in the Indenture, if an Event of Default occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in aggregate principal amount of the then Outstanding Securities by notice to the Company and the Trustee, may declare all the Securities to be due and payable immediately. The holders of a majority in principal amount of the Securities then Outstanding by written notice to the Trustee may rescind an acceleration and its consequences if the rescission is prior to a judgment or decree for the payment of the money due has been obtained by the Trustee as provided in the Indenture and if all existing Events of Default have been cured or waived except nonpayment of principal and/or interest that has become due solely because of the acceleration. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. Subject to certain limitations, holders of a majority in principal amount of the then Outstanding Securities issued under the Indenture may direct the Trustee in its exercise of any trust or power. The Company must furnish annually compliance certificates to the Trustee. The above description of Events of Default and remedies is qualified by reference to, and subject in its entirety by, the more complete description thereof contained in the Indenture. (xvii) AMENDMENTS, SUPPLEMENTS AND WAIVERS. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder -10- of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. (xviii) TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or any other capacity may become the owner or pledgee of the Securities and may otherwise deal with the Company or an Affiliate with the same rights it would have, as if it were not Trustee, subject to certain limitations provided for in the Indenture and in the TIA. Any Agent may do the same with like rights. (xix) NO RECOURSE AGAINST OTHERS. A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder of the Securities by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. (xx) GOVERNING LAW. THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS THEREOF. (xxi) AUTHENTICATION. The Securities shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent.
