The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. (d) The Company shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, consummate any Asset Sale, unless (i) the Company (or such Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by the Board of Directors (including as to the value of all noncash consideration) and set forth in an Officers' Certificate delivered to the Trustee) of the assets or Equity Interests issued or sold or otherwise disposed of and (ii) at least 75% of the consideration therefor is in the form of cash and/or Cash Equivalents or Qualified Consideration, and (iii) the Net Cash Proceeds received by the Company (or such Restricted Subsidiary, as the case may be) from such Asset Sale are applied within 360 days following the receipt of such Net Cash Proceeds, to the extent the Company (or such Restricted Subsidiary, as the case may be) elects, (a) to the redemption or repurchase of outstanding Indebtedness (I) that is either (A) secured Indebtedness or (B) Indebtedness of the Company that ranks equally with the Notes but has a maturity date that is prior to the maturity date of the Notes, in either case other than Subordinated Indebtedness or (II) that is Indebtedness of a Restricted Subsidiary and/or (b) to reinvest such Net Cash Proceeds (or any portion thereof) in properties or assets (including Equity Interests of a person that will become a Restricted Subsidiary as a result of such investment) that will be used in a Permitted Business. The balance of such Net Cash Proceeds, after the application of such Net Cash Proceeds as described in the immediately preceding clauses (a) and (b), shall constitute "Excess Proceeds." (e) When the aggregate amount of Excess Proceeds equals or exceeds $10 million (taking into account income earned on such Excess Proceeds), the Company shall be required to make a pro rata offer to all Holders and pari passu Indebtedness with comparable provisions requiring such Indebtedness to be purchased with the proceeds of such Asset Sale (an "Asset Sale Offer") to purchase the maximum principal amount or accreted value in the case of Indebtedness issued with an original issue discount of Notes and pari passu Indebtedness that may be purchased out of the Excess Proceeds, at a purchase price in cash in an amount equal to 100% of the principal amount thereof or the accreted value thereof, as applicable, plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), in accordance with the procedures set forth in Article 3 of the Indenture and the agreements governing such pari passu Indebtedness. To the extent that any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture.

Upon completion of such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero for purposes of the first sentence of this paragraph. 8. NOTICE OF REDEMPTION.

Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company or a Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. (c) Holders may not directly enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. (d) The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of all the Holders waive any existing Default or Event of Default and its consequences under the Indenture, except a continuing Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes. (e) The Company shall be required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company shall be required upon becoming aware of any Default or Event of Default to deliver to the Trustee a statement specifying such Default or Event of Default. The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal of, premium, if any, or interest on, the Notes) if it determines that withholding notice is in their interest. 13. TRUSTEE DEALINGS WITH COMPANY.

No director, officer, employee, -------------------------- incorporator or stockholder of the Company, as such, will have any liability for any obligations of the Company with respect to the Notes or the Indenture, or for any claim based on, or in respect or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note will waive and release any and all such liability. Such waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under federal securities laws and it is the view of the Commission that such a waiver is against public policy. 15. AUTHENTICATION.
