        QINETIQ GROUP PLC COMPLETES CASH TENDER OFFER FOR ALL ISSUED AND
                    OUTSTANDING SHARES OF ANALEX CORPORATION

On January 22, 2007, QinetiQ Group plc ('QinetiQ') announced it had signed an
agreement to acquire Analex Corporation ('Analex') and on January 30, 2007
initiated a recommended cash tender offer for all issued and outstanding shares
of common stock, par value $0.02 per share (the 'Shares') of Analex at $3.70 per
Share, net to seller in cash, without interest and subject to applicable
withholding taxes (the 'Offer').

QinetiQ today announces the completion of the Offer by its indirect wholly owned
subsidiary, Apollo Merger Sub Inc. (the 'Purchaser'). The Offer expired at 12:00
midnight, New York City time, on March 12, 2007. The depositary for the Offer
has advised QinetiQ that, as of the expiration date of the Offer, approximately
40,104,126 Shares, including 105,088 Shares that were tendered pursuant to
guaranteed delivery procedures, were validly tendered and not withdrawn in the
Offer, representing in excess of 90% of Analex's Shares issued and outstanding.
All validly tendered Shares have been accepted for payment in accordance with
the terms of the Offer.

All the conditions to the acquisition have now been satisfied and QinetiQ
intends to complete the acquisition of Analex through a short-form merger as
soon as practicable. In the short-form merger, all outstanding Shares not
purchased by the Purchaser in the Offer will be converted into the right to
receive $3.70 per share in cash.
