Carlisle Companies Incorporated Successfully Completes Tender Offer for Hawk Corporation

CHARLOTTE, NORTH CAROLINA, Dec. 1, 2010 — Carlisle Companies Incorporated (NYSE: CSL), and Hawk Corporation (NYSE Amex: HWK), today jointly announced the successful completion of the previously announced tender offer for all of the outstanding shares of Hawk Class A common stock (together with the associated preferred share purchase rights). The offer expired at 12:00 midnight, New York City time, at the end of the day on November 30, 2010.

On November 1, 2010, HC Corporation, a wholly owned subsidiary of Carlisle, commenced its tender offer to acquire all the outstanding shares of Hawk’s Class A common stock (together with the associated preferred share purchase rights) at a purchase price of $50.00 per share, net to the seller in cash, without interest, less any applicable withholding taxes. Based on a preliminary count by the depositary for the tender offer, a total of 7,321,448 shares of Hawk Class A common stock, including 312,450 shares tendered under guaranteed delivery procedures, representing approximately 94 percent of Hawk’s outstanding common stock, were validly tendered and not withdrawn in the tender offer. As of the expiration of the tender offer, Hawk had 7,759,063 shares of Class A common stock outstanding. All shares that were validly tendered and not withdrawn have been accepted for payment by HC Corporation in accordance with the terms of the tender offer and applicable law.

Carlisle, through its direct wholly owned subsidiary, HC Corporation, will acquire all of the remaining outstanding shares of Hawk Class A common stock by means of a merger under Delaware law. In the merger, each outstanding share of Hawk Class A common stock (other than shares to which the holder has properly exercised appraisal rights) will be converted into the right to receive $50.00 net to the seller in cash, without interest, less any applicable withholding taxes. As a result of the completion of the merger, Hawk’s Class A common stock will cease trading on the NYSE Amex. Carlisle expects that the merger will be implemented on an expedited basis pursuant to the short form merger procedure available under Delaware law.

Complete terms and conditions of the tender offer are set forth in the tender offer materials, including the offer to purchase and letter of transmittal, filed with the Securities and Exchange Commission by Carlisle and HC Corporation on November 1, 2010, with Carlisle’s tender offer statement on Schedule TO, as amended and supplemented.
