As of July 13, 2011, there was outstanding $48,301,000 aggregate principal amount of the Debentures. All capitalized terms used but not specifically defined in this Notice of Redemption shall have the meanings given to such terms in the Indenture and the Debentures.

The Redemption Price will become due and payable on the Redemption Date, and unless the Company defaults in making payment of the Redemption Price, interest on the Debentures will cease to accrue on and after the Redemption Date. Payment of the Redemption Price will be made on or after the Redemption Date upon presentation and surrender of the Debentures to the Trustee, which will be acting as the Paying Agent, as follows:

The Trustee has informed the Company that, as of the date of this Notice of Redemption, all custodians and beneficial holders of the Debentures hold the Debentures through Depository Trust Company (“DTC”) accounts and that there are no certificated Debentures in non-global form. Accordingly, all Debentures surrendered for redemption hereunder will be delivered through the transmittal procedures of DTC and redeemed in accordance with the procedures of DTC.

Holders of the Debentures have the right to exchange their Debentures into the Guarantor’s common stock, par value $0.01 per share, subject to the terms, conditions and adjustments specified in the Indenture and the Debentures; however, Debentures may only be surrendered for exchange prior to 5:00 p.m., New York City time, on August 16, 2011, the second Business Day immediately prior to the Redemption Date. In addition, holders of record as of August 1, 2011 will not be entitled to the regularly scheduled August 15, 2011 interest payment if they surrender their Debentures for exchange prior to 5:00 p.m., New York City time, on August 15, 2011. The Debentures are currently exchangeable at an Exchange Price of $30.9857 per share and an Exchange Rate of 32.2730 shares of the Guarantor’s common stock per $1,000 principal amount of Debentures.
