The Issuer or any of its Subsidiaries or any of its Affiliates may act as paying agent or registrar. 4. INDENTURE. The Issuer issued the Notes under an Amended and Restated Indenture, dated as of July 25, 1997, between the Issuer and the Trustee, as supplemented by an Amended and Restated First Supplemental Indenture, dated as of July 25, 1997 (collectively, the "Indenture"). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act of 1939"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act of 1939 for a statement of those terms. The Notes are general unsecured obligations of the Issuer, limited to $200 million aggregate principal amount. 5. REDEMPTION AT THE OPTION OF THE ISSUER. No sinking fund is provided for the Notes. The Notes will be subject to redemption at the option of the Issuer, in whole or in part, at any time and from time to time, upon not less than 30 nor more than 60 days' notice, at a redemption price equal to the sum of:(i) the principal amount of the Notes being redeemed plus accrued interest thereon to the redemption date; and (ii) the Make-Whole Amount (as defined below), if any, with respect to such Notes (the "Redemption Price"). If notice of redemption has been given as provided in Article Twelve of the Indenture and funds for the redemption of any Notes called for redemption shall have been made available on the redemption date referred to in such notice, such Notes will cease to bear interest on the date fixed for such redemption specified in such notice and the only right of the Holders of the Notes from and after the redemption date will be to receive payment of the Redemption Price upon surrender of such Notes in accordance with such notice. As used herein: "Make-Whole Amount" means, in connection with any optional redemption of any Notes by the Issuer pursuant to Article Twelve of the Indenture, the excess, if any, of: (a) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the date of redemption) that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third Business Day preceding the date notice of such redemption is given) from the respective dates on which such principal and interest would have been payable if such redemption had not been made, to the date of redemption; over (b) the aggregate principal amount of the Notes being redeemed. "Reinvestment Rate" means the yield on Treasury securities at a constant maturity corresponding to the remaining life (as of the date of redemption, rounded to the nearest month) to the stated maturity of the principal being redeemed (the "Treasury Yield") plus .20%. For purposes hereof, the Treasury Yield shall be equal to the arithmetic mean of the yields published in the Statistical Release (as defined below) under the heading "Week Ending" for "U.S. Government Securities-Treasury Constant Maturities" with a maturity equal to such remaining life; provided, that if no published maturity exactly corresponds with such remaining life, then the Treasury Yield shall be interpolated or extrapolated on a straight-line basis from the arithmetic means of the yields for the next shortest and next longest published maturities. For purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury Yield in the above manner, then the Treasury Yield shall be determined in the manner that most closely approximates the above manner, as reasonably determined by the Issuer. "Statistical Release" means the statistical release designated "H.15 (519)" or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination under the Indenture, then such other reasonably comparable index which shall be designated by the Issuer. If less than all the Notes are to be redeemed, the particular Notes or portions thereof to be redeemed shall be selected not more than 60 days and not less than 30 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption, either pro rata, by lot or by another method the Trustee shall deem fair and reasonable, and the aggregate principal amounts to be redeemed must be equal to $1,000 or any integral multiple thereof. 6. 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 Notes to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Notes to be redeemed on the Redemption Date, together with accrued interest thereon to the Redemption Date, is deposited with the Trustee or any paying agent prior to or on the Redemption Date, on and after such date interest shall cease to accrue on such Notes or portions thereof. 7. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in registered form, without coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000. A Holder may register the transfer of or exchange Notes in accordance with the Indenture. The registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Issuer shall not be required to exchange or register a transfer of (a) any Notes for a period of 15 days next preceding the first mailing or publication of notice of redemption of Notes to be redeemed, (b) any Notes selected, called or being called for redemption, in whole or in part, except, in the case of any Note to be redeemed in part, the portion thereof not so to be redeemed or (c) any Note if the Holder thereof has exercised its right, if any, to require the Issuer to repurchase such Note in whole or in part, except the portion of such Note not required to be repurchased. 8. PERSONS DEEMED OWNERS. The registered Holder of this Note may be treated as the owner of this Note for all purposes. 9. UNCLAIMED MONEY. The Trustee and each paying agent shall each return to the Issuer upon written request any money held by them for the payment of any amount with respect to the Notes that remains unclaimed for two years. After return to the Issuer, Holders entitled to the money must look to the Issuerfor payment as general creditors unless an applicable abandoned property law designates another person. 10. AMENDMENT; WAIVER. Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Notes may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding and (ii) certain defaults or noncompliance with certain provisions may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Notes at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Issuer and the Trustee may amend the Indenture or the Notes to cure any ambiguity, defect or inconsistency, or to comply with Article Nine of the Indenture, or to make any change that does not adversely affect the rights of any Holder of Notes. 11. DEFAULTS AND REMEDIES. Under the Indenture, Events of Default include, among others, (a) default in the payment of principal or premium, if any, when due; (b) default in the payment of any installment of interest when due, continued for 30 days; (c) default in the performance of any other covenant of the Issuer applicable to the Notes, continued for 60 days after written notice to the Issuer by the Trustee or to the Issuer and the Trustee, by the Holders of at least 25% in aggregate principal amount of the Notes then outstanding requiring the same to be remedied; (d) certain events of bankruptcy, insolvency or reorganization of the Issuer or any Restricted Subsidiary; and (e) default under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Issuer or any Restricted Subsidiary or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed of the Issuer or any Restricted Subsidiary resulting in the acceleration of such indebtedness, or any default in payment of such indebtedness (after expiration of any applicable grace periods and presentation of any debt instruments, if required), if the aggregate amount of all such indebtedness that has been so accelerated and with respect to which there has been such a default in payment shall exceed $10,000,000 and there has been a failure to obtain rescission or annulment of all such accelerations or to discharge all such defaulted indebtedness within 20 days after written notice of the type specified below. If any Event of Default shall occur and be continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Issuer (and to the Trustee, if given by the Holders), may declare the principal of all of the Notes and the interest, if any, accrued thereon to be due and payable immediately; provided, however, that the Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice in writing to the Issuer and the Trustee, may rescind andannul such declaration and its consequences if all defaults under such Indenture are cured or waived. No Holder of Notes then outstanding may institute any suit, action or proceeding with respect to, or otherwise attempt to enforce, such Indenture, unless (i) such Holder previously shall have given to the Trustee written notice of default and of the continuance thereof, (ii) the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding shall have made written request to the Trustee to institute such suit, action or proceeding and shall have offered to the Trustee such reasonable indemnity as it may require with respect thereto and (iii) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; provided that, the right of any Holder of any Note to receive payment of the principal of, premium, if any, or interest, if any, on such Note, on or after the respective due dates, or to institute suit for the enforcement of any such payment shall not be impaired or affected without the consent of such Holder. The Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes, provided that the Trustee may decline to follow such direction if the Trustee determines that such action or proceeding is unlawful or would involve the Trustee in personal liability. The Issuer is required to furnish to the Trustee annually a certificate as to compliance by the Issuer with all conditions and covenants under the Indenture. 12. TRUSTEE DEALINGS WITH THE ISSUER. Subject to certain limitations imposed by the Trust Indenture Act of 1939, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Issuer or its Affiliates and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee. 13. NO RECOURSE AGAINST OTHERS.
