ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

     On April 30, 2009, Endwave Corporation (“Endwave”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Microsemi Corporation (“Microsemi”), pursuant to which Microsemi purchased Endwave’s defense and security business (the “Business”), including all of the outstanding capital stock of Endwave Defense Systems, Inc. (“EDSI”). As consideration, Microsemi assumed certain liabilities associated exclusively with the Business and paid $28 million in cash. The Purchase Agreement contains standard representations and warranties as to the Business that survive for two years following closing. In connection with the transaction, Endwave entered into an indemnification agreement pursuant to which Endwave agreed to indemnify Microsemi for environmental, product liability and IP infringement claims related to Endwave’s operation of the Business prior to the closing date, as well as for any other excluded liability, and Microsemi agreed to indemnify Endwave for any claim related to the operation of the Business following the closing date and for any other assumed liability, subject in some cases to a customary deductible and limitation on maximum damages.

     Concurrently with the closing of the acquisition, Endwave entered into a transition services agreement and an employee transition services agreement with Microsemi pursuant to which Endwave will provide to Microsemi for a limited period of time certain transitional services, including human resources, information technology and product supply services.
