                 FINISAR AND INFINEON MODIFY TERMS OF AGREEMENT

SUNNYVALE, Calif.--(Market Wire) October 11, 2004-- Finisar Corporation (NASDAQ:
FNSR) and Infineon Technologies AG, Munich (FSE/NYSE: IFX) announced today that
they have agreed to modify the terms of a previously announced agreement under
which Finisar is to acquire Infineon's Fiber Optics Business Unit based in
Berlin, Germany. The terms were modified in part due to the operating results
for this business unit during the past six months. Under the terms of the
modified agreement, Finisar will issue approximately 110 million shares of
Finisar common stock to Infineon compared to approximately 135 million shares
that would have been issuable under the original agreement. Following the
transaction, Infineon will hold a 33 percent equity interest in Finisar. In
addition, Infineon has agreed to provide financial assistance with respect to
the costs of restructuring the operations of the Fiber Optics Business Unit and
integrating those operations with Finisar's following the closing.

The transaction is subject to approval by Finisar's shareholders, applicable
regulatory approvals and other customary closing conditions. Jerry Rawls,
President and CEO of Finisar, and Frank Levinson, Chairman and Chief Technology
Officer of Finisar, who own an aggregate of approximately 16% of the outstanding
Finisar shares, have entered into agreements with Infineon to vote their shares
in favor of the transaction. The companies have already received the required
antitrust clearances in the U.S. and Europe.

As previously announced, the acquisition will involve the transfer of Infineon's
fiber optic development, manufacturing, and certain marketing activities and
approximately 1,200 employees. The Infineon Fiber Optics Business Unit develops,
manufactures and markets a broad range of fiber optic datacom and telecom
modules supporting the common MSA standards, BIDI components that allow
bi-directional transmission on a single fiber for fiber-to-the-home applications
(FTTH), and plastic optical fiber (POF) components that are used in automotive
applications, specifically, for entertainment and safety systems.

Pending the approval of Finisar's shareholders, the transaction is now expected
to close in the fourth calendar quarter of this year.

At closing, Mr. Thomas Seifert, CEO of Infineon's Memory Products Group, is
expected to join the Finisar Board of Directors.
