The Securities do not have the benefit of any sinking fund obligations. The Securities are subject to optional redemption by the Company in whole at any time, or in part from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed, plus interest accrued on such principal amount to the Redemption Date plus a Premium calculated as of the Redemption Date, as provided in the Third Supplemental Indenture dated as of November 13, 1998. Upon the occurrence of a Change of Control, the Company shall be required to make an Offer to Purchase all or a specified portion of the Securities at a purchase price in cash equal to 101% of the principal amount thereof on any Purchase Date plus accrued and unpaid interest, if any, to such Purchase Date. If the Company, any Restricted Subsidiary or any Eligible Joint Venture consummates an Asset Disposition, under certain circumstances, the Company shall be required to make an Offer to Purchase up to all or a specified portion of the Securities at a purchase price in cash equal to 100% of the principal amount thereof on any Purchase Date, plus accrued and unpaid interest, if any, to such Purchase Date, in an amount equal to any Net Cash Proceeds from such an Asset Disposition that are not used to reinvest in the business of the Company and/or repay in a permanent reduction of Debt of the Company or Debt of its Restricted Subsidiaries or Eligible Joint Ventures.

A-5 In the event of purchase, pursuant to an Offer to Purchase, of this Security in part only, a new Security or Securities for the portion hereof not purchased shall be issued in the name of the Holder hereof upon surrender of this Security to the Trustee for cancellation thereof. Following the Rating Event Date (and provided no Event of Default or Default shall exist on the Rating Event Date), substantially all the covenants contained in the Indenture (excluding the covenant relating to the Company's obligation to make an Offer to Purchase Securities upon the occurrence of a Change of Control) will cease to apply to the Securities. In their place, certain other covenants regarding restrictions on liens and the ability of the Company to merge or consolidate with or into any other Person, or to transfer or lease assets will apply to the Securities. The Indenture contains provisions for defeasance at any time of the entire Debt of the Company with respect to this Security or certain restrictive covenants and Events of Default with respect to this Security, including, without limitation, covenants relating to Offers to Purchase, in each case upon compliance with certain conditions set forth in the Indenture.

The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences in each case with respect to the Securities of such series. In addition, without the consent of any Holder of a Security, the Indenture and the Securities may be amended and supplemented to cure any ambiguity or inconsistency, make other changes that shall not adversely affect the rights of the Holders or certain other matters specified in the Indenture. Any such consent or waiver by the Holder 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. A-6 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver, or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to certain suits described in the Indenture, including any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein (or, in the case of any purchase of this Security required to be made pursuant to an Offer to Purchase, on or after the Purchase Date). 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 premium, if any) and interest on this Security at the times, place, manner and rate, and in the coin or currency, herein prescribed. 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 the Borough of Manhattan, The City of New York (which initially shall be the Corporate Trust Office of the Trustee), 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, shall be issued to the designated transferee or transferees. The Securities are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 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. A-7 A director, officer, employee, stockholder or incorporator of the Company shall not have any liability for any obligations of the Company under this Security or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting this Security waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of this Security.
