Item 1.01. Entry into a Material Definitive Agreement

Argon ST, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger dated as of June 30, 2010 (the “Merger Agreement”) with The Boeing Company, a Delaware corporation (“Parent”), and Vortex Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Parent has agreed to cause Merger Sub to commence a tender offer (the “Offer”) to purchase all of the outstanding shares of Common Stock, par value $0.01 per share, of the Company (the “Shares”), for $34.50 per Share (the “Offer Price”), net to the seller in cash, without interest thereon and subject to applicable withholding taxes.

The Merger Agreement provides that the Offer will commence within five business days after the date of the Merger Agreement, and will remain open for at least 20 business days (including the day on which the Offer is commenced). Pursuant to the Merger Agreement, after the consummation of the Offer, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving as a wholly owned subsidiary of Parent. Upon completion of the Merger, each Share outstanding immediately prior to the effective time of the Merger (excluding those Shares that are held by Parent, Merger Sub and the Company or any of the Company’s subsidiaries) will be canceled and converted into the right to receive the Offer Price in cash (without interest and subject to applicable withholding taxes). If Merger Sub holds 90% or more of the outstanding Shares immediately prior to the Merger, it may effect the Merger as a short-form merger pursuant to Delaware General Corporation Law. Otherwise, the Company may hold a special stockholders’ meeting to obtain stockholder approval of the Merger.

Subject to the terms and conditions of the Merger Agreement, the Company has granted Merger Sub an irrevocable one-time option (the “Top-Up Option”) to purchase an aggregate number of newly issued Shares that, when added to the number of Shares owned by Parent and Merger Sub at the time of such exercise, constitutes one Share more than 90% of the Shares then outstanding immediately after the issuance of the Top-Up Option Shares on a fully diluted basis, subject to applicable regulatory requirements and there being sufficient authorized Shares available for issuance. The Top-Up Option is exercisable only after Shares have been accepted for payment pursuant to the Offer.

Completion of the Offer is subject to customary conditions, including (i) that there shall have been validly tendered and not validly withdrawn prior to the expiration of the Offer, when added to the number of Shares already owned by Parent, a majority of the Shares outstanding (determined on a fully diluted basis), and (ii) the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

The Merger Agreement contains representations, warranties and covenants of the parties customary for transactions of this type. The Company has also agreed not to solicit or initiate discussions with third parties regarding other proposals to acquire the Company and it has agreed to certain restrictions on its ability to respond to such proposals, subject to the fulfillment of certain fiduciary requirements of the Company’s board of directors. The Merger Agreement also contains customary termination provisions for the Company and Parent and provides that, in connection with the termination of the Merger Agreement under specified circumstances involving competing transactions or a change in the Company’s board of directors’ recommendation, the Company may be required to pay Parent a termination fee of $28.0 million.

The Merger Agreement is attached to this Current Report on Form 8-K to provide the Company’s stockholders with information regarding the terms of the Merger Agreement and is not intended to modify or supplement any factual disclosures about the Company or Parent in the Company’s or Parent’s public reports filed with the Securities and Exchange Commission (the “SEC”). In particular, the Merger Agreement and this summary of terms are not intended to be, and should not be relied upon as, disclosures regarding any facts or circumstances relating to the Company or Parent. The representations and warranties have been negotiated with the principal purpose of (i) establishing the circumstances under which Merger Sub may have the right not to consummate the Offer, or Parent or the Company may have the right to terminate the Merger Agreement, and (ii) allocating risk between the parties, rather than establishing matters as facts. The

representations and warranties may also be subject to a contractual standard of materiality different from that generally applicable under federal securities laws.

The foregoing description of the Offer, Merger, and Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K and incorporated in this report by reference.

Concurrently with the execution and delivery of the Merger Agreement, each of Terry L. Collins, Victor F. Sellier and Thomas E. Murdock (including, in each case, certain affiliates thereof), together representing ownership of more than approximately 34.3% of the outstanding Shares, and approximately 31.2% of the Shares on a fully diluted basis, entered into a tender and voting agreement (collectively, the “Tender and Voting Agreements”) with Parent and Merger Sub whereby Messrs. Collins, Sellier and Murdock (and certain affiliates party to the Tender and Voting Agreements) committed, among other things, subject to the terms and conditions of the Tender and Voting Agreements, to tender all of their respective Shares in the Offer. The Tender and Voting Agreements automatically terminate upon the termination of the Merger Agreement or the occurrence of certain other events. The foregoing description of the Tender and Voting Agreements does not purport to be complete and is qualified in its entirety by reference to the Tender and Voting Agreements, which are filed as Exhibits 2.2, 2.3 and 2.4, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

Item 8.01. Other Events.

On June 30, 2010, the Company issued a press release, a copy of which is furnished as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference in this Current Report on Form 8-K, announcing the execution of the Merger Agreement.
