1.01     Entry into a Material Definitive Agreement.

         On August 29, 2006, Emulex Corporation, a Delaware corporation
("Emulex"), Shasta Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of Emulex ("Merger Sub"), and Sierra Logic, Inc., a Delaware
corporation ("Sierra Logic") entered into an Agreement and Plan of Merger (the
"Agreement") whereby, upon the terms and subject to the conditions set forth in
the Agreement, Merger Sub will be merged with and into Sierra Logic at the
effective time (the "Merger"). Following the Merger, the separate corporate
existence of Merger Sub will cease, and Sierra Logic shall continue as a wholly
owned subsidiary of Emulex. Under the terms of the Agreement, Emulex will
acquire Sierra Logic for a transaction value of up to approximately $180 million
in cash plus assumed debt, assumed Sierra Logic stock options, and the issuance
of employee equity incentive compensation. A portion of the cash consideration
payable to the Sierra Logic shareholders will be retained in escrow for
indemnification of Emulex, if applicable. The board of directors and
shareholders of Sierra Logic have approved the Merger, and it is expected to be
completed on or near September 30, 2006, subject to certain closing conditions,
including regulatory approval.

         The foregoing description of the Merger does not purport to be
complete and is qualified in its entirety by reference to the Agreement and
Plan of Merger attached as Exhibit 2.1 to this Current Report on Form 8-K.

         A copy of the press release announcing the transaction is furnished as
Exhibit 99.1 hereto, and shall not be deemed "filed" for purposes of Section 18
of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by
reference in any filing under the Securities Exchange Act of 1934 or the
Securities Act of 1933, whether made before or after the date hereof and
irrespective of any general incorporation language in any filings.
