Item 8.01. Other Events.
     On March 26, 2007, Agere Systems Inc. (“Agere”) issued a press release updating its revenue outlook for the second quarter of its fiscal year 2007. Agere announced that it expects revenues in the second quarter ending March, 2007 to be approximately 12 percent lower than the $372 million reported in the quarter ended December, 2006. In addition, Agere announced that it expects GAAP earnings per share to increase substantially versus the December, 2006 quarter, reflecting the sale of its facility in Orlando, Florida and continued strong expense control.
     LSI Logic Corporation (“LSI”), Atlas Acquisition Corp. and Agere are parties to an Agreement and Plan of Merger, dated as of December 3, 2006, pursuant to which Atlas Acquisition Corp., a wholly-owned subsidiary of LSI, will merge with and into Agere.
