Red Hat®, Inc.

The merger will create an open source powerhouse to accelerate and support the rapidly growing adoption of Red Hat Linux and open source solutions in enterprise and Internet applications and a new generation of post-PC-centric computing. Red Hat expects the merger to close by January 27, 2000.

The transaction will be completed in a stock for stock merger in which Red Hat will issue up to 6,624,344 shares for all of the outstanding securities of Cygnus. The transaction will be accounted for under the pooling of interests method. The transaction is subject to approval by Cygnus' shareholders, the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary closing conditions. Matthew Szulik, the president of Red Hat, will lead the combined companies as president and CEO.

The merger will make Red Hat, Inc. the largest company in the world dedicated to providing open source technology, information and services, offering the full spectrum of open source software and support --- from enterprise deployments to embedded and handheld platforms.

"Cygnus has enormous experience and technology leadership in software development and embedded platforms," said Matthew Szulik, president of Red Hat, Inc. "The merger will create a single, worldwide source that lets developers rapidly create Linux applications for servers and small devices --- accelerating the adoption of open source technologies in enterprises worldwide."
