HRLY Herley Industries, Inc. (MM)

Kratos Defense & Security Solutions, Inc. (Nasdaq:KTOS), a leading National Security Solutions provider, today announced that the initial offering period of its previously announced tender offer for the outstanding shares of Herley Industries, Inc. (Nasdaq:HRLY) has been completed successfully.

The depositary for the tender offer has advised Kratos that, as of the expiration of the initial offering period, midnight, Eastern Time, on Thursday, March 24, 2011 (the end of the day on Thursday), 13,225,532 shares representing approximately 93.7% of Herley's outstanding common stock were tendered and not withdrawn prior to the expiration of the initial offering period, including 302,994 shares representing approximately 2.1% of Herley's outstanding common stock which were tendered by notice of guaranteed delivery.  The tendered shares represent approximately 84.7% of Herley's outstanding common stock on a fully-diluted basis. All shares that were validly tendered and not withdrawn have been accepted for purchase and payment, and all holders of these shares will be paid promptly.

Kratos has commenced a subsequent offering period for 3 business days starting on March 25, 2011. The subsequent offering period will expire at midnight, Eastern Time, on March 29, 2011. During this subsequent offering period, Herley stockholders who did not previously tender their shares into the offer may do so and will promptly receive the same $19.00 per share cash consideration paid during the initial offering period. The guaranteed delivery procedures may not be used during the subsequent offering period and shares tendered during the subsequent offering period may not be withdrawn. In addition, shares tendered during the initial offering period may not be withdrawn.

After expiration of the subsequent offering period, Kratos expects to complete the acquisition of Herley through a short-form merger under Delaware law in which shares of Herley common stock not purchased in the tender offer will be converted into the right to receive $19.00 per share in cash, without interest.  Pursuant to the merger, Herley will become a wholly owned subsidiary of Kratos and shares of Herley's common stock will cease to be traded on the NASDAQ Global Select Market.
