ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT. AGREEMENT AND PLAN OF MERGER On November 8, 2006, Essex Corporation, a Virginia corporation ("ESSEX"), entered into a definitive Agreement and Plan of Merger (the "MERGER AGREEMENT") with Northrop Grumman Space & Mission Systems Corp., an Ohio corporation ("NORTHROP GRUMMAN"), and Eagle Transaction Corporation, a Virginia corporation and wholly owned subsidiary of Northrop Grumman ("MERGERCO"). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, MergerCo will be merged with and into Essex Corporation, with Essex continuing as the surviving corporation and a wholly owned subsidiary of Northrop Grumman (the "Merger"). Pursuant to the terms of the Merger Agreement, upon the effectiveness of the Merger, each issued and outstanding share of Essex common stock will be converted into the right to receive $24.00 in cash, without interest, and each outstanding Essex stock option, whether or not vested or exercisable, will be converted into the right to receive the excess, if any, of the $24.00 per share merger consideration over the per share exercise price of the stock option. In addition, Essex has agreed, among other things and subject to certain exceptions as described in the Merger Agreement, (i) to conduct its business in the ordinary course consistent with past practice during the interim period between the execution of the Merger Agreement and the consummation of the Merger, (ii) not to engage in certain transactions during such period, (iii) to cause a shareholder meeting to be held promptly to consider approval of the Merger Agreement, and (iv) subject to certain limited exceptions to permit the board of directors to comply with their fiduciary duties, not to enter into discussions or negotiations concerning, or to provide information in connection with, alternative business combination transactions. Consummation of the Merger is subject to a number of conditions, including approval by Essex's shareholders, absence of any law or order prohibiting the consummation of the Merger, expiration or termination of the applicable Hart-Scott Rodino Antitrust Improvements Act of 1976 waiting period, and certain other customary conditions. Under applicable Virginia law, approval by Essex's shareholders will require the affirmative vote of holders of at least 2/3 of the shares of Essex common stock entitled to vote. Pursuant to the terms of the Merger Agreement, Northrop Grumman and Essex each have certain termination rights. In the case of Northrop Grumman, it will have the right to terminate the Merger Agreement if, among other reasons, the Essex board of directors withdraws, modifies, qualifies or amends its recommendation of the Merger in a manner adverse to Northrop Grumman, and in the case of Essex, it will have the right to terminate the Merger Agreement if, among other reasons, it determines to enter into an unsolicited alternative business combination transaction that the board finds to be more favorable to Essex's shareholders than the Merger, after following certain procedures set forth in the Merger Agreement. Upon termination of the Merger Agreement under specified circumstances, Essex will be required to pay Northrop Grumman a termination fee of $22.5 million. Additionally, if the Merger cannot be closed or is delayed for longer than six months because of regulatory impediments (subject to the right of Northrop Grumman to extend the termination date for an additional 90 days), Northrop Grumman has agreed to reimburse Essex for out-of-pocket expenses (including reasonable legal fees and expenses) incurred in connection with the Merger of up to $1 million. In connection with entering into the Merger Agreement, three stockholders (Len Moodispaw, John Hannon, and Terry Turpin), who collectively own 11 percent of Essex's outstanding common stock and who are also members of the Essex's board of directors, have signed voting agreements with Northrop Grumman, agreeing to vote their shares in favor of the merger and in opposition to any competing acquisition proposals. In addition, the voting agreements provide that the stockholders may not transfer their shares (or any options or other similar rights with respect to Essex stock) to any other party during the term of the agreements. The term of the voting agreements extend until the earlier of the closing of the Merger or 6 months after the termination of the Merger Agreement for any reason.
