Item 2. Identity and Background.

(a)-(c) and (f): The name of the person filing this statement is Mercury Computer Systems, Inc., a Massachusetts corporation (“Mercury”). The principal executive offices of Mercury are located at 201 Riverneck Road, Chelmsford, Massachusetts 01824. Mercury designs, manufactures and markets commercially-developed, high-performance embedded, real-time digital signal and image processing sub-systems and software for specialized defense and commercial computing markets.

In military reconnaissance and surveillance platforms, Mercury’s sub-systems process real-time radar, video, sonar and signals intelligence data. Mercury provides microwave products for enhanced communications capabilities in military and commercial applications.

Pursuant to Rule 13d-4 of the Act, Mercury expressly declares that the filing of this Schedule 13D shall not be construed as an admission that any person is, for the purposes of Section 13(d) and/or Section 13(g) of the Act or otherwise, the beneficial owner of any securities covered by this Schedule 13D held by any other person.

Attached hereto as Schedule I, and incorporated herein by reference, is additional information required by this Item 2(a)-(c) and (f) with respect to each executive officer and director of Mercury as of the date hereof.

(d) During the last five years, neither Mercury, nor to the best knowledge of Mercury, has any of the persons listed on Schedule I, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, neither Mercury, nor to the best knowledge of Mercury, has any of the persons listed on Schedule I, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

On June 8, 2012, Micronetics, Mercury and Wildcat Merger Sub Inc. (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, and subject to the conditions thereof, (i) Mercury will acquire all of the outstanding shares of Micronetics common stock for $14.80 per share in cash, without interest, and (ii) Merger Sub will be merged with and into Micronetics with Micronetics continuing as the surviving corporation and a wholly owned subsidiary of Mercury (the “Merger”). The anticipated aggregate amount of funds required by Mercury to consummate the Merger is approximately $73.1 million taking into account the purchase of all outstanding shares of Micronetics common stock, payments to holders of vested options and payments of related transaction fees and expenses.

Concurrently with the execution and delivery of the Merger Agreement, and as a condition and inducement to the willingness of Mercury and Merger Sub to enter into the Merger Agreement, each of Micronetics’ Chief Executive Officer, President, and Chief Financial Officer, each of Micronetics’ directors and one holder of approximately 12.5% of the outstanding shares of Micronetics common stock have entered into a voting agreement (each a “Voting Agreement” and collectively the “Voting Agreements”) covering a total of 915,975 shares of Micronetics common stock legally or beneficially held by such signatories. Under the Voting Agreements, each signatory has agreed to vote his or her shares in favor of the Merger and against any proposal made in opposition to or in competition with the Merger. The Voting Agreements provide that they will terminate upon the earlier of the effective time of the Merger and any termination of the Merger Agreement.

Neither Mercury nor Merger Sub paid any additional consideration to the signatories of the Voting Agreements (or their respective affiliates) to induce such signatories to entire into the Voting Agreements.

The foregoing description of the Merger Agreement and the Voting Agreements does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement and the form of Voting Agreement, copies of which are filed as Exhibits hereto.

During the term of the Voting Agreements, each signatory thereto has also granted an irrevocable proxy appointing Mercury or any designee of Mercury to vote each signatory’s shares of Micronetics’ common stock with respect to the matters described in clauses (i), (ii) and (iii) of the preceding paragraph.
