The aggregate principal amount of the 8 3/4% Senior Notes shall be limited to $100,000,000; provided, however, that the authorized aggregate principal amount of the 8 3/4% Senior Notes may be increased above such amount by a Board Resolution to such effect.

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 shall either (i) be paid to the Person in whose name such 8 3/4% Senior Note (or one or more Predecessor Securities) is registered at the close of business on the Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of the 8 3/4% Senior Notes not less than 10 days prior to such Special Record Date, or (ii) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the 8 3/4% Senior Notes may be listed or traded, and upon such notice as may be required by such exchange or quotation system, all as more fully provided in the Indenture.

Such Global Securities shall bear the legends set forth in the form of 8 3/4% Senior Note contained herein. SECTION 2.09. Form of Securities. The 8 3/4% Senior Notes shall be substantially in the form contained in ARTICLE FIVE hereof. SECTION 2.10. Securities Registrar. The Trustee shall initially serve as Securities Registrar. SECTION 2.11. Defeasance and Discharge; Covenant Defeasance. Article Fourteen of the Indenture, including without limitation, Sections 1402 and 1403 thereof, shall apply to the 8 3/4% Senior Notes. SECTION 2.12. Sinking Fund Obligations. The Company has no obligation to redeem or purchase any 8 3/4% Senior Note pursuant to any sinking fund or analogous provisions (including payments made in cash in anticipation of future sinking fund obligations) or upon the happening of a specified event or, except as provided in Section 4.03 hereof, at the option of a Holder thereof. ARTICLE THREE Optional Redemption of the 8 3/4% Senior Notes SECTION 3.01. Redemption Price. The Company shall have the right to redeem the 8 3/4% Senior Notes, in whole or in part, at any time at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to (but excluding) the Redemption Date plus the Make-Whole Premium, if any (the "Redemption Price"). The amount of the Make-Whole Premium with respect to any 8 3/4% Senior Note (or portion thereof) to be redeemed will be equal to the excess, if any, of: (i) the sum of the present values, calculated as of the Redemption Date, of: (A) each interest payment that, but for such redemption, would have been payable on the 8 3/4% Senior Note (or portion thereof) being redeemed on each Interest Payment Date occurring after the Redemption Date (excluding any accrued and unpaid interest for the period prior to the Redemption Date); and (B) the principal amount that, but for such redemption, would have been payable at the Maturity Date of the 8 3/4% Senior Note (or portion thereof) being redeemed; over (ii) the principal amount of the 8 3/4% Senior Note (or portion thereof) being redeemed. The present values of interest and principal payments referred to in clause (i) above will be determined in accordance with generally accepted principles of financial analysis. Such present values will be calculated by discounting the amount of each payment of interest or principal from the date that each such payment would have been payable, but for the redemption, to the Redemption Date at a discount rate equal to the Treasury Yield (as defined below) plus 20 basis points. The Make-Whole Premium shall be calculated by an independent investment banking institution of national standing appointed by the Company; provided, that if the Company 7 fails to make such appointment at least 45 Business Days prior to the Redemption Date, or if the institution so appointed is unwilling or unable to make such calculation, such calculation shall be made by BNY Capital Markets, Inc., or, if such firm is unwilling or unable to make such calculation, by an independent investment banking institution of national standing appointed by the Trustee (in any such case, an "Independent Investment Banker"). SECTION 3.02. Make-Whole Premium. For purposes of determining the Make- Whole Premium, "Treasury Yield" means a rate of interest per annum equal to the weekly average yield to maturity of United States Treasury Notes that have a constant maturity that corresponds to the remaining term to maturity of the 8 3/4% Senior Notes, calculated to the nearest 1/12th of a year (the "Remaining Term"). The Treasury Yield shall be determined as of the third Business Day immediately preceding the applicable Redemption Date. The weekly average yields of United States Treasury Notes shall be determined by reference to the most recent statistical release published by the Federal Reserve Bank of New York and designated "H.15 (519) Selected Interest Rates" or any successor release (the "H.15 Statistical Release"). If the H.15 Statistical Release sets forth a weekly average yield for United States Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield shall be equal to such weekly average yield. In all other cases, the Treasury Yield shall be calculated by interpolation, on a straight-line basis, between the weekly average yields on the Unites States Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the United States Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields so calculated by interpolation shall be rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded upward. If weekly average yields for United States Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield shall be calculated by interpolation of comparable rates selected by the Independent Investment Banker. SECTION 3.03. Partial Redemption. If the 8 3/4% Senior Notes are only partially redeemed pursuant to this ARTICLE THREE, the 8 3/4% Senior Notes shall be redeemed pro rata or by lot or by any other method that the Trustee deems fair and appropriate. SECTION 3.04. Notice of Optional Redemption. If the Company elects to exercise its right to redeem all or some of the 8 3/4% Senior Notes pursuant to this ARTICLE THREE, the Company or the Trustee shall mail a notice of such redemption to each Holder of a 8 3/4% Senior Note that is to be redeemed not less than 30 days and not more than 60 days before the Redemption Date. 8 ARTICLE FOUR Covenants Applicable to the 8 3/4% Senior Notes SECTION 4.01. Limitation on Liens on Voting Securities of Subsidiaries. After the date hereof and so long as any of the 8 3/4% Senior Notes remain Outstanding, the Company shall not, and shall not permit any Subsidiary to, pledge or grant a security interest in, or permit any pledge, security interest or other lien upon, any Voting Securities of any Subsidiary owned directly or indirectly by the Company or any of its Subsidiaries to secure any Indebtedness, without making effective provision to secure the 8 3/4% Senior Notes equally and ratably with the other Indebtedness and any other Indebtedness similarly entitled to be equally and ratably secured. This covenant shall not apply, however, to: (1) any pledge, security interest or other encumbrance upon any Voting Securities of any Subsidiary existing as of May 25, 2000; (2) the creation or existence of any pledge, security interest or other encumbrance upon any Voting Securities of any Subsidiary (a) created at the time of the Company's and/or a Subsidiary's acquisition (including acquisition through merger or consolidation) of such Voting Securities or within 24 months after the Company's and/or a Subsidiary's acquisition of such Voting Securities to secure all or a portion of the purchase price for such Voting Securities, (b) existing on such Voting Securities at the time of the Company's and/or a Subsidiary's acquisition of such Voting Securities or (c) created solely to secure obligations incurred to finance the refurbishment, improvement, installation, development or construction of any asset of the Company or any Subsidiary, which obligations are incurred no later than 24 months after completion of such refurbishment, improvement, installation, development or construction, or (3) any extension, renewal or refunding of any pledge, security interest or other encumbrance described in clauses (1) and (2). For purposes of this Section 4.01, "Indebtedness" means all indebtedness, whether or not represented by bonds, debentures, notes or other securities, created or assumed by the Company or any Subsidiary for the repayment of borrowed money. All indebtedness for borrowed money secured by a lien upon property owned by the Company or any Subsidiary and upon which indebtedness for borrowed money the Company or such Subsidiary customarily pays interest, although the Company or such Subsidiary has not assumed or 9 become liable for the payment of such indebtedness for borrowed money, shall for purposes of this Section 4.01 be deemed to be Indebtedness of the Company or such Subsidiary. All indebtedness for borrowed money of others guaranteed as to payment of principal by the Company or any Subsidiary or in effect guaranteed by the Company or such Subsidiary through a contingent agreement to purchase such indebtedness for borrowed money shall be deemed for purposes of this Section 4.01 to be Indebtedness of the Company or such Subsidiary, but no other contingent obligation of the Company or any Subsidiary in respect of indebtedness for borrowed money or other obligations incurred by others shall for purposes of this Section 4.01 be deemed to be Indebtedness of the Company or such Subsidiary. In case the Company or any Subsidiary shall propose to pledge, mortgage, hypothecate or grant a security interest in any Voting Securities of any Subsidiary to secure any Indebtedness, other than as permitted by clauses (1), (2) and (3) in the second preceding paragraph, the Company will prior thereto give written notice thereof to the Trustee, and the Company will prior to or simultaneously with such pledge, mortgage, hypothecation or grant of security interest, by supplemental indenture executed to the Trustee (or to the extent legally necessary to another trustee or an additional or separate trustee), in a form reasonably satisfactory to the Trustee, effectively secure (for so long as such other Indebtedness shall be so secured) all the 8 3/4% Senior Notes equally and ratably with such Indebtedness and with any other Indebtedness for borrowed money similarly entitled to be equally and ratably secured. SECTION 4.02. Limitation on Issuance or Disposition of Voting Securities of Restricted Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary to, issue, sell, assign, transfer or otherwise dispose of, directly or indirectly, any Voting Securities of any Restricted Subsidiary (except to the Company or to one or more Restricted Subsidiaries or for the purpose of qualifying directors); provided, however, that this covenant shall not apply if: (1) all or any part of such Voting Securities are issued, sold, assigned, transferred or otherwise disposed of in a transaction for consideration that is at least equal to the fair value of such Voting Securities, as determined by the Board of Directors acting in good faith, or (2) the issuance, sale, assignment, transfer or other disposition is required to comply with the order of a court or regulatory authority of competent jurisdiction, other than an order issued at the Company's or a Restricted Subsidiary's request. SECTION 4.03. Put Right of Holders Upon a Change of Control Triggering Event. In the event that there occurs a Change of Control Triggering Event, each Holder of 8 3/4% Senior Notes shall have the right, at such Holder's option, to require the Company to purchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder's 10 8 3/4% Senior Notes during the Repurchase Period, at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but excluding) the Repurchase Date (the "Repurchase Price"). The Company shall mail or cause to be mailed notice of the occurrence of a Change of Control Triggering Event (the "Change of Control Triggering Event Notice") to the Trustee and to each Holder of the 8 3/4% Senior Notes within 30 days following any Change of Control Triggering Event. The Change of Control Triggering Event Notice shall state: (i) that a Change of Control Triggering Event has occurred; (ii) that all 8 3/4% Senior Notes tendered during the Repurchase Period will be accepted for repurchase; (iii) the date by which the repurchase right must be exercised, which date is the last day of the Repurchase Period; (iv) the Repurchase Price; and (v) the procedure which a Holder of 8 3/4% Senior Notes must follow to exercise the repurchase right. To exercise this repurchase right, a Holder of 8 3/4% Senior Notes must deliver during the Repurchase Period a written notice to the Company (or an agent designated by the Company for such purpose in the Change of Control Triggering Event Notice) of the Holder's exercise of such right (the "Repurchase Notice"), together with the 8 3/4% Senior Note with respect to which the repurchase right is being exercised, duly endorsed for transfer to the Company. The Repurchase Notice shall be irrevocable, must be received by the Company prior to the last day of the Repurchase Period and shall state the name in which the 8 3/4% Senior Note is registered on the Securities Register and the principal amount of the 8 3/4% Senior Note to be repurchased. The Company shall repurchase the 8 3/4% Senior Note with respect to which this repurchase right is being exercised on the fifth Business Day after receipt of the Repurchase Notice (the "Repurchase Date"). 8 3/4% Senior Notes repurchased pursuant to this Section 4.03 shall be delivered to the Trustee and canceled as provided in Section 310 of the Indenture.
