Item 1.01 Entry into a Material Definitive Agreement.

On September 16, 2009, Hi-Shear Technology Corporation, a Delaware corporation (“Hi-Shear” or the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Chemring Group PLC, a company organized under the laws of England and Wales (“Chemring” or “Parent”) and Parkway Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Parent (“Merger Sub”).

The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company continuing as the surviving corporation and a wholly-owned subsidiary of Parent.  As of the effective time of the Merger, each outstanding share of common stock, par value $0.001 per share, of the Company (“Common Stock”) will be cancelled and converted into the right to receive an amount in cash equal to $19.18 per share, subject to the terms and conditions set forth in the Merger Agreement.  Parent will fund the aggregate cash consideration by utilizing a credit facility with Lloyds Banking Group plc.

Consummation of the Merger is not subject to a financing condition, but is subject to various other conditions, including approval of the Merger Agreement and the transaction contemplated therein by the Company’s stockholders, expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, and other customary closing conditions.

The Company has made various representations and warranties and agreed to certain covenants in the Merger Agreement, including covenants relating to the Company’s conduct of its business between the date of the Merger Agreement and the effective time of the Merger, public disclosures and other matters.

The Merger Agreement contains certain termination rights for both the Company and Parent.  The Merger Agreement provides that, upon termination under specified circumstances, the Company would be required to pay Parent a termination fee of $4 million.

The Merger Agreement has been approved by the Board of Directors of the Company, based, in part, upon the recommendation of a special committee of the Board that was established to consider strategic alternatives, and the Board has resolved to recommend that the stockholders of the Company vote in favor of the adoption and approval of the Merger Agreement and the transactions contemplated therein.  The Company’s President, Chief Executive Officer and Chairman, George W. Trahan, has entered into a Stockholder Agreement with Parent and Merger Sub whereby he granted an irrevocable proxy to Parent to vote certain shares of Common Stock in favor of the Merger, subject to the terms and conditions of the Stockholder Agreement.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached hereto as Exhibit 2.1, and is incorporated herein by reference.

2

The Merger Agreement has been included to provide investors and security holders with information regarding its terms.  It is not intended to provide any other factual information about the Company.  The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of that agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company, Parent or Merger Sub or any of their respective subsidiaries or affiliates.  Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 16, 2009, in connection with the Company’s entry into the Merger Agreement, Mr. Trahan entered into an amendment (the “Amendment”) to his Employment Agreement with the Company dated as of February 28, 2009 (the “Employment Agreement”).  Pursuant to the Amendment, Mr. Trahan will no longer be entitled to severance or continuing benefits under his Employment Agreement in the event that he is terminated, regardless of the reason for termination.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, which is attached hereto as Exhibit 10.1, and is incorporated herein by reference.

Item 8.01 Other Events.

On September 16, 2009, the Company issued a press release relating to the proposed Merger with Chemring.  A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
