                 ENDWAVE ANNOUNCES EMPLOYEE OPTIONS ACCELERATION

    SUNNYVALE, Calif., Jan. 5 /PRNewswire-FirstCall/ -- Endwave Corporation
(Nasdaq: ENWV), a leading provider of high frequency RF modules for
telecommunications networks, defense electronics and homeland security systems,
today announced that its Board of Directors has accelerated the vesting of
certain unvested, "out-of-the-money" stock options previously awarded to
employees and officers that have exercise prices of $21.00 per share or higher.
As a result, options to purchase approximately 340,000 shares of Endwave stock
became exercisable immediately.

    As a result of the acceleration, options to purchase 338,995 shares of
Endwave's common stock, which would otherwise have vested over the next three
years, are now fully vested. This includes options to purchase 137,348 shares
held by executive officers, options to purchase 201,647 shares held by other
employees and no options held by non-employee directors. The options represent
approximately 26% of the total options presently outstanding. The total weighted
average option exercise price per share is $27.68.

    The primary purpose of the acceleration of vesting of these options was to
eliminate future compensation expense Endwave would otherwise recognize in its
statement of operations with respect to these options upon the adoption of
Financial Accounting Standards Board Statement No. 123 (revised 2004),
Share-Based Payment ("SFAS 123(R)"). SFAS 123(R), which was adopted by Endwave
on January 1, 2006, requires that compensation expense associated with stock
options be recognized in the company's statement of operations, rather than
disclosed as a footnote to Endwave's consolidated financial statements.

    As a result of the acceleration, Endwave expects to reduce the stock option
expense it otherwise would be required to record in connection with the
accelerated options by approximately $4.4 million over the next three years.
