Item 5. Other Events and Required FD Disclosure

On October 28, 2003, a wholly owned subsidiary of Applied Micro Circuits Corporation, a Delaware corporation (“AMCC”), merged with and into JNI Corporation, a Delaware corporation (“JNI”), with JNI being the surviving company. Upon consummation of the merger, JNI became a wholly owned subsidiary of AMCC. The merger was completed under the terms of the Agreement and Plan of Merger, dated as of August 28, 2003, between AMCC, JNI and Azure Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of AMCC. In the merger, each outstanding share of JNI common stock was converted into the right to receive $7.00 in cash, without interest. Additionally, in connection with the merger, AMCC assumed all outstanding stock options issued pursuant to JNI’s stock option plans, which became options to purchase shares of AMCC common stock. The total purchase price (including the value of assumed options and transaction costs) paid by AMCC in the transaction was approximately $209.2 million and was paid out of AMCC’s general corporate funds.

JNI is a provider of enterprise storage connectivity products. AMCC intends to continue JNI’s business and to integrate it with AMCC’s operations.

The foregoing description of the merger does not purport to be complete and is qualified in its entirety by reference to the complete text of the Agreement and Plan of Merger filed as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.
