CryoLife Exercises Right to Convert Preferred Stock into Common Stock

ATLANTA, GA… (June 4, 2007)… CryoLife, Inc. (NYSE:  CRY), a biomaterials, medical device and tissue processing company, announced today it is exercising its right to convert its 6% convertible preferred stock (Cusip # 228903209; NYSE: CRYPR) into the company's common stock on June 25, 2007. The preferred stock contains provisions that allow the company to convert its preferred stock into common stock if the common stock closes above $12.06 per share for any 20 trading days out of a consecutive 30 trading day period. This condition was satisfied at the close of trading on the New York Stock Exchange on June 4, 2007.

Each share of $50 convertible preferred stock is convertible into 6.2189 shares of the Company's common stock based on a conversion price of $8.04 per share. If any fractional shares of the Company's common stock result from a conversion, the Company will make a cash payment equal to the value of the fractional shares of common stock. As of June 4, 2007, there were 277,600 shares of preferred stock outstanding, convertible into 1,726,366 shares of common stock. All outstanding shares of the convertible preferred stock are held through the Depository Trust Company, whose nominee, Cede & Co., is the sole record holder of the shares. The conversion will take place effective June 25, 2007 at 5:00 p.m. Eastern Time. No action by beneficial holders is required. All inquiries should be addressed to Suzanne K. Gabbert, Corporate Secretary, at (678) 290-4327. Immediately following the effective date of the conversion, the convertible preferred stock will cease trading and will be delisted from the New York Stock Exchange.

The Company will also issue 69,054 shares of the Company's common stock, with a total value of $833,000 at $12.06 per share, to the preferred shareholders as a dividend make-whole payment, in lieu of cash, for the aggregate dividends on the preferred shares that the Company is obligated to pay through April 1, 2008. Upon conversion of the preferred stock, the Company anticipates taking a non-cash charge to earnings related to the derivative recorded for the dividend make-whole payment. The amount of this charge, which could be material, cannot be determined prior to June 25, 2007.
