Red Hat Amends Stock and Debenture Repurchase Program

Raleigh

United States, September 29, 2008

Red Hat, Inc. (NYSE: RHT), the world's leading provider of open source solutions, today announced that its Board of Directors has amended the Company's previously announced program for the repurchase of its common stock and convertible debentures to increase by an additional $125.0 million the amount of debentures that may be purchased under the program.

The Company's Board of Directors also extended the duration of the repurchase program. As extended, the program will expire on the earlier of (i) November 30, 2008, or (ii) a determination by the Company's Board of Directors, Chief Executive Officer or Chief Financial Officer to discontinue the program.

Repurchases of common stock and convertible debentures may be effected, from time to time, either on the open market or in privately negotiated transactions, as applicable.

The timing and the amount of any repurchased common stock and any convertible debentures will be determined by the Company's management based on its evaluation of market conditions and other factors. Repurchases may also be made under a Rule 10b5-1 plan, which would permit repurchases when the Company might otherwise be precluded from doing so under insider trading laws. Any repurchased common stock will be available for use in connection with its stock plans and for other corporate purposes. All repurchased convertible debentures will be retired and cancelled.

The repurchase program will be funded using the Company's working capital. As of August 31, 2008, the Company had cash, cash equivalents and investments of approximately $1.43 billion.

Red Hat had approximately 191.7 million shares of common stock outstanding as of September 26, 2008.
