QINETIQ GROUP PLC EXTENDS CASH TENDER OFFER FOR ALL ISSUED

AND OUTSTANDING SHARES OF ANALEX CORPORATION

Fairfax, VA, February 28, 2007 – QinetiQ Group plc (“QinetiQ”) announced today that Apollo Merger Sub Inc., an indirect wholly owned subsidiary of QinetiQ (the “Purchaser”), has extended the expiration date of its cash tender offer for all outstanding shares of common stock, par value $0.02 per share (the “Shares”), of Analex Corporation (“Analex”) at $3.70 per Share, net to the seller in cash, without interest (and subject to applicable withholding taxes) (the “Offer”) until midnight, New York City time, on March 12, 2007. QinetiQ also announced that as of midnight on February 27, 2007, approximately 13,032,024 Shares had been tendered and not withdrawn, representing approximately 31.6% of Analex’s Shares issued and outstanding and issuable upon conversion of warrants, preferred stock and convertible notes. In addition, a group of Analex’s major stockholders has pledged to tender a number of Shares issuable upon conversion of warrants, preferred stock and convertible notes equal to approximately 59% of Analex’s Shares issued and outstanding and issuable upon conversion of warrants, preferred stock and convertible notes. To date, approximately 90.7% of voting stock has been tendered or pledged and not withdrawn.

QinetiQ confirmed that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 applicable to the Offer had expired as of February 14, 2007, which satisfied one of the conditions necessary for the consummation of the pending acquisition. QinetiQ further confirmed that, as expected, other regulatory conditions necessary for the consummation of the pending acquisition have not yet been satisfied so that it cannot yet complete its Offer. QinetiQ expects to be able to complete its Offer in March 2007, pending receipt of required regulatory clearances.

This announcement is not an offer to purchase Shares or a solicitation of an offer to sell Shares. The Offer is being made solely by the Offer to Purchase and the related Letter of Transmittal. The Offer to Purchase dated January 30, 2007, the Letter of Transmittal, as amended, and related materials may be obtained free of charge by directing such requests to MacKenzie Partners, Inc., 105 Madison Avenue, New York, NY 10016, or by calling MacKenzie Partners, Inc. toll free at (800) 322-2885.

Investors and stockholders of Analex should read the Tender Offer Statement on Schedule TO, as amended, the Offer to Purchase and any other documents relating to the Offer that are filed with the United States Securities and Exchange Commission (“SEC”) because they contain important information about the tender offer.
