Item 1.02 Termination of a Material Definitive Agreement.

     On January 12, 2005, Finisar Corporation (“Finisar”) issued a press release responding to a notice that it received on January 11, 2005 from Infineon Technologies AG (“Infineon”) purporting to terminate the purchase agreement between the parties dated October 11, 2004, which provides for the acquisition by Finisar of Infineon’s fiber optics business unit in exchange for approximately 110 million shares of Finisar common stock. The material terms of the purchase agreement were described in Finisar’s Form 8-K Report dated October 11, 2004, to which the purchase agreement was attached as Exhibit 2.7. As noted in the press release attached hereto as Exhibit 99.1, Infineon’s notice alleges, among other things, that the termination of the agreement was based on Finisar’s breach of the agreement. Finisar does not believe that such a breach has taken place. The reporting of this event under Item 1.02 does not constitute an acknowledgment by Finisar that the agreement has been properly terminated.

     In a press release issued by Infineon on January 11, 2005 regarding its purported termination of the agreement, Infineon stated that it will assess its legal options to recover damages by way of an arbitration proceeding in Germany. As noted in the press release attached hereto as Exhibit 99.1, Finisar intends to defend itself vigorously against any legal proceedings that may be instituted by Infineon and to assert appropriate claims for recovery of damages caused by Infineon. Finisar is unable at this time to provide information regarding the damages that may be claimed by either party in, or the possible outcome of, any legal proceeding that may arise in connection with the agreement.
