SPECIAL MEETING OF STOCKHOLDERS

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Hi-Shear Technology Corporation Stockholder:

        Our board of directors, based, in part, on the unanimous recommendation of a special committee consisting of three independent directors, has unanimously approved a merger agreement and a merger pursuant to which Hi-Shear Technology Corporation will become a wholly-owned subsidiary of Chemring Group PLC.

        If the merger is completed, holders of our common stock will be entitled to receive $19.18 in cash, without interest and less applicable withholding taxes, for each share of our common stock that they own at the effective time of the merger. Receipt of the merger consideration will be a taxable transaction to our stockholders for U.S. federal income tax purposes.

        Our stockholders will be asked at a special meeting to approve and adopt the merger agreement and the merger. Based, in part, on the unanimous recommendation of the special committee, our board of directors has unanimously approved resolutions (i) approving the merger agreement and the merger, (ii) determining that the merger agreement and the terms and conditions of the merger are fair, advisable and in the best interests of Hi-Shear Technology Corporation and our stockholders, and (iii) directing that the merger and merger agreement be submitted for approval at a special meeting of our stockholders. In reaching this determination, our board of directors considered a variety of factors that are discussed in the attached proxy statement. Our board of directors unanimously recommends that all of our stockholders vote FOR the approval and adoption of the merger agreement and the merger.

        Our board of directors also unanimously recommends that our stockholders vote FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear Technology Corporation, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger.

        The affirmative vote of a majority of the issued and outstanding shares of our common stock is required to approve and adopt the merger agreement and the merger. Each holder of our common stock is entitled to one vote per share. Proxies returned to us that are properly signed and dated but not marked to indicate your voting preference, will be counted as votes FOR approval and adoption of the merger agreement and the merger, and FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear Technology Corporation for the aforementioned reasons. If you do not vote or do not instruct your broker, bank or other nominee to vote, it will have the same effect as voting against the proposal to approve and adopt the merger agreement and the merger, so please vote.

        As previously announced, our Annual Meeting of Stockholders originally scheduled to be held at 10:00 a.m. on October 30, 2009, has been postponed indefinitely.

        The date, time and place of the special meeting to consider and vote upon the proposal to approve and adopt the merger agreement and the merger are as follows:

November 19, 2009
2:00 p.m., local time
24225 Garnier Street, Torrance, California 90505-5355

        The proxy statement attached to this letter provides you with information about the special meeting of our stockholders and the proposed merger. We encourage you to read the entire proxy statement carefully.

        Your vote is very important. Whether or not you plan to attend the special meeting, if you are a holder of our common stock please take the time to vote by completing, signing, dating and mailing the enclosed proxy card to us. If you attend the special meeting, you may vote in person even if you previously returned your proxy.

QUESTIONS AND ANSWERS ABOUT THE MERGER

         The following questions and answers are provided for your convenience, and briefly address some commonly asked questions about the Hi-Shear Technology Corporation special meeting of stockholders, the merger agreement and the proposed merger. These questions and answers may not address all questions that may be important to you as a stockholder. You should carefully read this entire proxy statement, including each of the annexes, and the other documents to which we have referred you.

         Throughout this proxy statement, "Hi-Shear," "we" and "our" refer to Hi-Shear Technology Corporation, a Delaware corporation, "Chemring" refers to Chemring Group PLC, a company organized under the laws of England and Wales and "Merger Sub" refers to Parkway Merger Sub, Inc., a Delaware corporation. Also, we refer to the merger between Hi-Shear and Merger Sub as the "merger"; and the agreement and plan of merger, dated as of September 16, 2009, by and among Chemring, Merger Sub and Hi-Shear as the "merger agreement."

Q:    Why am I receiving the proxy materials?

        A:     We sent you this proxy statement and the enclosed proxy card because the board of directors of Hi-Shear is soliciting your proxy to vote at a special meeting of Hi-Shear stockholders in connection with a proposal to approve and adopt a merger agreement whereby Hi-Shear would become a wholly-owned subsidiary of Chemring. You may submit a proxy if you complete, date, sign and return the enclosed proxy card. You are also invited to attend the special meeting in person, although you do not need to attend the special meeting to have your shares voted at the special meeting.

Q:    What will I receive in the merger?

        A:     If the merger is completed, you will be entitled to receive $19.18 in cash, without interest and less any applicable withholding taxes, for each share of our common stock that you own at the effective time of the merger. For example, if you own 100 shares of our common stock, you will receive $1,918.00 in cash, less any applicable withholding taxes, in exchange for those shares.

Q:    What will happen in the merger with any options that I hold to acquire Hi-Shear common stock under the company's stock incentive plans?

        A:     Optionees will be entitled to receive cash for each share of our common stock subject to their options (whether or not vested), as of the effective time of the merger, in an amount equal to the difference between (i) the cash price of $19.18 to be paid with respect to our common stock in the merger and (ii) the exercise price per share of their options, less applicable withholding taxes.

Q:    How does Hi-Shear's board of directors recommend I vote?

        A:     Based, in part, on the unanimous recommendation of a special committee consisting of three independent directors, our board of directors has unanimously adopted resolutions approving the merger agreement and the merger, determining that the merger agreement and the terms and conditions of the merger are fair, advisable and in the best interests of Hi-Shear and our stockholders and directing that the merger agreement be submitted for approval at a special meeting of our stockholders. Our board of directors unanimously recommends that all of our stockholders vote FOR the approval and adoption of the merger agreement and the merger. The reasons for our board of directors' determination are set forth in detail in this proxy statement. Our board of directors also unanimously recommends that you vote FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger.

Q:    Who will own Hi-Shear after the merger?

        A:     After the merger, Hi-Shear will be a wholly-owned direct or indirect subsidiary of Chemring. As a result of the receipt of cash in exchange for Hi-Shear common stock, you will no longer benefit from any increase in Hi-Shear's value, nor will you acquire an ownership interest in Chemring.

Q:    What do I need to do now?

        A:    We urge you to read this proxy statement carefully, including its annexes, and to consider how the merger affects you. Then mail your completed, dated and signed proxy card in the enclosed return envelope as soon as possible so that your shares can be voted at the special meeting of our stockholders.

Q:    What happens if I do not return a proxy card?

        A:     If you fail to return your proxy card, your shares will not be counted for purposes of determining whether a quorum is present at the special meeting. In addition, the failure to return your proxy card will have the same effect as voting against the merger.

Q:    What happens if I return a proxy card that is not marked to indicate my voting preference?

        A:     Proxies returned to us that are properly signed and dated but not marked to indicate your voting preference will be counted as votes FOR approval and adoption of the merger agreement and the merger and FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger.

Q:    What vote is needed to approve and adopt the merger agreement?

        A:     The affirmative vote of a majority of the issued and outstanding shares of our common stock is required to approve and adopt the merger agreement. Each holder of our common stock is entitled to one vote per share. In connection with the transactions contemplated by the merger agreement, George W. Trahan, Hi-Shear's Chairman, Chief Executive Officer and President, entered into a stockholder agreement with Chemring and Merger Sub pursuant to which Mr. Trahan granted Chemring an irrevocable proxy to vote certain of his shares of Hi-Shear common stock comprising approximately 32.4% of our issued and outstanding common stock as of the record date, in favor of the merger agreement and the merger.

Q:    May I vote in person?

        A:     Yes. If your shares are not held in "street name" through a broker, bank or other nominee, you may attend the special meeting of our stockholders and vote your shares in person, rather than signing and returning your proxy card. If your shares are held in "street name," you must get a proxy from your broker, bank or other nominee in order to attend the special meeting and vote your shares in person.

Q:    Do I need to attend the special meeting in person?

        A:     No. You do not have to attend the special meeting in order to vote your shares of our common stock. Your shares can be voted at the special meeting without attending by mailing your completed, dated and signed proxy card in the enclosed return envelope.

Q:    May I change my vote after I have mailed my signed proxy card?

        A:     Yes. You may change your vote at any time before your proxy card is voted at the special meeting. You can do this in one of three ways. First, you can send a written, dated notice to our Secretary stating that you would like to revoke your proxy. Second, you can complete, date, and submit a new proxy card. Third, you can attend the meeting and vote in person. Your attendance alone will not revoke your proxy. If you have instructed a broker to vote your shares, you must follow directions received from your broker to change your instructions.

Q:    If my broker holds my shares in "street name," will my broker vote my shares for me?

        A:     Your broker will not be able to vote your shares without instructions from you. You should instruct your broker to vote your shares by following the procedures provided by your broker. Without instructions, your shares will not be voted, which will have the same effect as a vote against the merger.

Q:    Should I send in my Hi-Shear stock certificates now?

        A:     No. After the merger is completed, you will receive written instructions for exchanging your shares of our common stock for the merger consideration of $19.18 in cash, without interest and less applicable withholding taxes, for each share of our common stock that you own at the effective time of the merger, subject to the terms of the merger agreement.

Q:    When do you expect the merger to be completed?

        A:     We are working toward completing the merger as quickly as possible. We currently expect the merger to be completed in the fourth quarter of 2009. However, we cannot assure you when or if the merger will occur. In addition to stockholder approval, the other closing conditions contained in the merger agreement must be satisfied or waived. Either Chemring or Hi-Shear may terminate the merger agreement if the merger has failed to occur by March 1, 2010 and the terminating party has not caused that failure by its breach of the merger agreement.

Q:    What if the proposed merger is not completed?

        A:     If the merger is not completed, we will continue our current operations and our status as a publicly held company.

Q:    Am I entitled to appraisal rights?

        A:     Under Delaware law, Hi-Shear stockholders of record who do not vote in favor of the merger agreement and the merger and who properly deliver a written demand for appraisal prior to the vote on adoption of the merger agreement will be entitled to exercise appraisal rights in connection with the merger and obtain payment in cash for the judicially-determined fair value of their shares of Hi-Shear common stock if the merger is completed. The provisions of the Delaware General Corporation Law ("DGCL") relating to appraisal rights are attached as Annex C to this proxy statement. Failure to take all of the steps required under Delaware law may result in the loss of any appraisal rights. If holders of more than 10% of our outstanding common stock exercise their appraisal rights, then all of the conditions to closing will not be satisfied and Chemring will not be required to close the merger.

Q:    Will the merger be a taxable transaction for me?

        A:     If you are a U.S. taxpayer, your receipt of cash in the merger will be treated as a taxable sale of your Hi-Shear common stock for U.S. federal income tax purposes. In general, you will recognize gain or loss equal to the difference between (i) the amount of cash you receive in the merger in exchange for your shares of our common stock and (ii) the adjusted tax basis of your shares of our

common stock. You should consult your tax advisor on how specific tax consequences of the merger apply to you.

Q:    What other matters will be voted on at the special meeting?

        A:     Our stockholders are also being asked to vote at the special meeting in favor of adjourning the meeting, if adjournments are determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger proposal, by permitting the solicitation of additional proxies from our stockholders if there are not sufficient votes at the time of the special meeting to approve and adopt the merger proposal. In order to be approved, this proposal requires the approval of a majority of the votes represented in person or by proxy at the special meeting. Pursuant to Delaware law and our bylaws, only matters set forth in the notice of meeting may be considered at the special meeting of stockholders.

Q:    When is Hi-Shear going to have its 2009 Annual Meeting of Stockholders?

        A:     We originally scheduled the 2009 Annual Meeting of Stockholders to be held at 10:00 a.m. on October 30, 2009. The 2009 Annual Meeting has been postponed indefinitely. If the merger with Chemring is not completed, we will reschedule the 2009 Annual Meeting of Stockholders and notify stockholders of the date, time and location of the rescheduled meeting.

Q:    Who can help answer my questions?

        A:     If you would like additional copies, without charge, of this proxy statement or if you have questions about the merger, including the procedures for voting your shares, you should contact our proxy solicitor:

        Background and Reasons for the Merger.     A special committee of our board of directors, comprised of three independent directors, oversaw a process of investigating potential transactions with third parties to maximize value for our stockholders. This process began in November 2008 and culminated with the execution of the merger agreement on September 16, 2009. For a description of this process, including:

•

the solicitation of interest from a potential list of 72 sophisticated and knowledgeable parties (including both financial sponsors and strategic buyers),



•

the deliberations of the special committee and our board of directors in connection with that process and its results, and



•

the negotiations with Chemring,

see "The Merger—Background of the Merger."

        The special committee and our board of directors also considered the challenges we face as a "micro-cap" thinly traded public company and a smaller company than many of our competitors in the aerospace and defense industry.

        At a meeting of the special committee held on September 15, 2009, the special committee unanimously resolved to recommend that our board of directors approve the merger agreement and the merger with a subsidiary of Chemring. At a meeting of our board of directors held on the same date, our board of directors received the special committee's recommendation and unanimously determined to accept that recommendation, and to approve the merger agreement and the merger with a subsidiary of Chemring and recommend it to our stockholders. See "The Merger—Hi-Shear's Board of Directors' Recommendation."

        In making its determination and recommendation set forth above, our special committee considered, among other things, the following:

•

its knowledge of the current state of our business, including our financial condition, operations, business plans, management, competitive position and prospects;



•

the fact that the $19.18 per share merger consideration to be received by Hi-Shear stockholders represented a premium of approximately 61.4% over the closing price per share as reported on the NYSE Amex on September 15, 2009 (which was the date the special committee unanimously recommended to our board of directors, and our board of directors unanimously approved, the merger agreement with Chemring);



•

the opinion of Lazard to the special committee and our board of directors to the effect that, as of September 15, 2009, and based upon and subject to the assumptions, qualifications and limitations set forth in its written opinion of that date, the merger price of $19.18 per share in cash to be received by Hi-Shear stockholders pursuant to the merger agreement was fair, from a financial point of view, to such stockholders (the full text of Lazard's written opinion, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Lazard in connection with its opinion, is attached as Annex B to this proxy statement and should be read in its entirety in conjunction with the information contained in "The Merger—Financial Advisor's Opinion Regarding the Merger Consideration"), as well as the presentation Lazard made to the special committee on that date regarding the analyses performed in connection with its fairness opinion;



•

the fact that the merger consideration is all cash, which provides certainty of value to Hi-Shear stockholders compared to a transaction in which they would receive stock or other non-cash consideration;

8

Table of Contents

•

the experience, reputation and financial capabilities of Chemring, including Chemring's knowledge of the markets that Hi-Shear serves and the belief that Hi-Shear's customers would benefit from the continued service of Hi-Shear's experienced employees post-acquisition; and



•

its belief that our shares were unlikely to trade at prices substantially above their pre-merger announcement price for a significant period.

        The special committee also considered, among other things, its knowledge of the process that it had closely supervised to investigate potential transactions and ultimately negotiate the merger agreement with Chemring, including the fact that 72 parties (including both financial sponsors and strategic acquirors) were contacted, that 31 of those parties entered into confidentiality agreements with Hi-Shear, that 14 of those parties submitted preliminary indications of interest in acquiring Hi-Shear and three parties including Chemring, had submitted final proposals. In the course of its deliberations, the special committee considered a number of additional material positive factors and a number of additional potentially negative factors regarding the merger.

        Our special committee concluded that the potentially negative factors were substantially outweighed by the opportunity presented by the merger for our stockholders to monetize their Hi-Shear investment for $19.18 per share in cash within a relatively short period of time if the merger conditions were satisfied, which the special committee believed would maximize the value of their shares. Accordingly, the special committee unanimously concluded that the merger was in the best interests of our stockholders.

        In making its determination and recommendation set forth above, our board of directors considered the unanimous determination and recommendation of the special committee, having regard to the independence of its members, their business experience and their active role in overseeing, with the advice of experienced legal and financial advisors, the process of investigating potential transactions that led to the negotiation of the merger agreement with Chemring. In addition, our board of directors took account of the same considerations, including the same material positive and potentially negative factors, that the special committee had considered and reached the same conclusion as the special committee with respect to the benefits of the merger for our stockholders.

        See "The Merger—Reasons for the Merger."

        Hi-Shear's Board of Directors' Recommendation.     Based, in part, on the unanimous recommendation of a special committee of three independent directors, our board of directors has unanimously approved resolutions:

•

approving the merger agreement and the merger;



•

determining that the merger agreement and the terms and conditions of the merger are fair, advisable, and in the best interests of Hi-Shear and our stockholders;



•

directing that the merger agreement be submitted for approval at a special meeting of our stockholders; and



•

recommending that all of our stockholders vote for the approval and adoption of the merger agreement and the merger.

        See "The Merger—Reasons for the Merger" and "The Merger—Hi-Shear Board of Directors' Recommendation."

        Financial Advisor's Opinion Regarding the Merger Consideration.     In connection with the evaluation of the proposed merger by the special committee of our board directors and our board of directors, the special committee's financial advisor, Lazard Frères & Co. LLC ("Lazard"), rendered a written opinion to the special committee and our board of directors on September 15, 2009 that, as of such date and subject to the assumptions, qualifications and limitations set forth in its opinion, the merger

consideration of $19.18 in cash, without interest, per share of Hi-Shear common stock was fair, from a financial point of view, to the Hi-Shear stockholders. The full text of Lazard's written opinion, dated September 15, 2009, is attached to this proxy statement as Annex B. We encourage you to read this opinion carefully in its entirety for a description of the procedures followed, assumptions made, matters considered and limitations on the review taken. Lazard's opinion is addressed to the special committee and our board of directors and does not constitute a recommendation to any stockholder as to any matters relating to the merger.

        See "The Merger—Financial Advisor's Opinion Regarding the Merger Consideration."

        Interests of Hi-Shear's Executive Officers and Directors in the Merger.     In considering the recommendation of Hi-Shear's board of directors that Hi-Shear stockholders vote in favor of the proposal to approve and adopt the merger agreement and the merger, Hi-Shear stockholders should be aware that officers and directors of Hi-Shear may have interests in the merger that are different from, or in addition to, the interests of Hi-Shear stockholders generally. These interests include, among others, the acceleration of vesting and removal of restrictions with respect to stock options and other stock-based awards; and continuation of rights to indemnification and liability insurance. Hi-Shear's board of directors was aware of and considered these interests when it unanimously approved the merger agreement and the merger.

        As of the record date, directors and executive officers of Hi-Shear, and their affiliates, beneficially owned approximately 2,488,544 shares of Hi-Shear common stock, or approximately 36.3% of the issued and outstanding Hi-Shear common stock at that date.

        See "The Merger—Interests of Hi-Shear's Executive Officers and Directors in the Merger" and "The Special Meeting—Vote Required."

        Material United States Federal Income Tax Consequences of the Merger.     The exchange of shares of our common stock for the cash merger consideration will be a taxable transaction to our stockholders for U.S. federal income tax purposes. In general, each stockholder will recognize a gain or loss equal to the difference, if any, between the cash payment received and the stockholder's tax basis in the shares surrendered in the merger.

        See "The Merger—Material United States Federal Income Tax Consequences of the Merger."

        Tax matters can be complicated, and the tax consequences of the merger to you will depend on the facts of your own situation. You should consult your own tax advisor to fully understand the tax consequences of the merger to you.

        Appraisal Rights.     Under Delaware law, Hi-Shear stockholders of record who do not vote in favor of the merger agreement and the merger and who properly deliver a written demand for appraisal to Hi-Shear prior to the vote for adoption of the merger agreement will be entitled to exercise appraisal rights in connection with the merger and obtain payment in cash for the judicially-determined fair value of their shares of Hi-Shear common stock if the merger is completed. The provisions of the DGCL relating to appraisal rights are attached as Annex C to this proxy statement. Failure to take all of the steps required under Delaware law may result in the loss of any appraisal rights. If holders of more than 10% of our outstanding common stock exercise their appraisal rights, then all of the conditions to closing will not be satisfied and Chemring will not be required to close the merger.

        See "The Merger Agreement—Appraisal Rights."

        Delisting and Deregistration of Hi-Shear Common Stock.     If the merger is completed, our common stock will no longer be traded on the NYSE Amex and will be deregistered under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

        Regulatory Matters.     Under the Hart-Scott-Rodino Antitrust Improvements Act ("HSR Act"), Chemring and Hi-Shear cannot consummate the merger until each party has filed the required notification forms and, if requested, furnished additional information to the Federal Trade Commission and the Antitrust Division of the United States Department of Justice, and the specified waiting period expires or is terminated. On October 8, 2009 and October 9, 2009, Hi-Shear and Chemring, respectively, filed HSR Act notification forms with the Department of Justice and the Federal Trade Commission. The initial waiting period will expire on November 9, 2009 unless terminated earlier or extended by the issuance of a request for additional information and documentary material.

        As Chemring may be deemed to be a foreign person as defined by the Exon-Florio provision of the Defense Production Act of 1950 ("Exon-Florio"), the merger is subject to Exon-Florio, which provides for review of certain transactions by the inter-agency Committee on Foreign Investment in the United States ("CFIUS"). Chemring and Hi-Shear were required to file a joint voluntary notification to CFIUS concerning the merger. Chemring and Hi-Shear made such filing on October 9, 2009, and received an acknowledgement of receipt from the Department of Treasury on October 13, 2009. Under Exon-Florio, CFIUS may review the transaction for a period of 30 days, and, if warranted, may further investigate the transaction for an additional 45-day period.

        In addition, as the transaction will result in ownership and control of Hi-Shear by foreign persons as defined by the International Traffic in Arms Regulations ("ITAR"), Hi-Shear is required to notify the U.S. Department of State Directorate of Defense Trade Controls ("DDTC") under the provisions of 22 C.F.R. 122.4(b) at least 60 days in advance of the transaction. Hi-Shear filed its notice with DDTC on September 17, 2009. The parties thereafter are required to observe a 60-day waiting period before completing the merger. Certain precautionary measures may be required by DDTC prior to the transaction to avoid unauthorized exports of technical data or defense services controlled by ITAR.

        Litigation Related to the Merger.     On October 1, 2009, Francis Bartholomew filed a Class Action Complaint against Hi-Shear, our board of directors and Merger Sub in the Superior Court of the State of California, Los Angeles County. The Class Action Complaint alleges the defendants breached their fiduciary duties in connection with the Merger by purportedly failing to maximize shareholder value and/or to disclose all material information with respect to the transaction. On behalf of the public stockholders of Hi-Shear, Francis Bartholomew seeks an order enjoining the proposed transaction and/or an award of monetary damages. Hi-Shear believes the Class Action is without merit and intends to defend this matter vigorously. The defense of this litigation will require us to incur legal fees and costs. An unfavorable resolution of any such litigation surrounding the Merger could delay or prevent the consummation of the Merger, result in significant costs, or both.

Equity Plans

        Stock Options.     At the effective time of the merger, each then outstanding option to purchase our stock that was granted under the 1993 Stock Option Plan and the 2006 Stock Award Plan will be deemed fully vested and be cancelled, and each holder of such option will be entitled to receive in exchange for such option an amount in cash equal to the product of (i) the number of shares for which such option is exercisable and (ii) the excess of the per share price of $19.18 to be paid with respect to our common stock in the merger over the per share exercise price of such option, less any applicable tax withholdings. As of the record date, 28,719 options to purchase the common stock of Hi-Shear were issued and outstanding.

        Restricted Stock Units.     As of the record date, 8,860 restricted stock units were outstanding that are settleable in shares of our common stock. Under the terms of the merger agreement, as of the effective time of the merger, each outstanding restricted stock unit (whether vested or unvested) will be cancelled and be converted into the right to receive the per share price of $19.18 to be paid with

respect to our common stock in the merger, less any applicable tax withholdings, without any further restrictions.

Market Price and Dividend Data

        Our common stock is quoted on the NYSE Amex under the symbol "HSR." On September 15, 2009, the last full trading day prior to the public announcement of the proposed merger, our common stock closed at $11.88. On October 13, 2009, the last practicable trading day prior to the date of this proxy statement, our common stock closed at $19.12. We urge stockholders to obtain a current quotation of our common stock.

The Merger Agreement

        General.     The following is a summary of certain of the principal provisions of the merger agreement and is qualified in its entirety both by the more detailed description that appears later in this proxy statement and by the full text of the merger agreement contained in Annex A.

        The merger agreement contemplates the merger of a wholly-owned subsidiary of Chemring with and into Hi-Shear, with Hi-Shear surviving the merger. Upon completion of the merger, Hi-Shear will become a wholly-owned direct or indirect subsidiary of Chemring. The merger will become effective upon the later of (i) acceptance by the Delaware Secretary of State of our filing of a certificate of merger, or (ii) a subsequent time of effectiveness that we and Chemring agree to and specify in the certificate of merger. Upon completion of the merger, holders of our common stock will be entitled to receive $19.18 in cash, without interest and less applicable withholding taxes, in exchange for each share of our common stock held at the effective time of the merger.

        The merger agreement contains representations and warranties by Hi-Shear and by Chemring that are customary for agreements of this nature. The merger agreement also contains customary covenants, including Hi-Shear's covenant to carry on our business in the ordinary and usual course of business and in a manner consistent with past practices and to obtain Chemring's consent before engaging in certain activities. In addition, Hi-Shear has agreed to provide Chemring with notice of certain developments in its business.

        Acquisition Proposals by Third Parties.     We have agreed that, except as permitted by the merger agreement, we will not authorize or permit any of our officers, directors, employees, agents and representatives, including any investment banker, attorney or accountant retained by us to, directly or indirectly:

•

initiate, solicit, or knowingly encourage or facilitate any inquiries, proposals or offers with respect to any acquisition proposal (as defined in the merger agreement and described below in the section captioned "The Merger Agreement—Definitions of Acquisition Proposal and Superior Proposal");



•

engage or participate in any negotiations concerning, or furnish any nonpublic information relating to us to any third party in connection with, any acquisition proposal;



•

approve, endorse or recommend any acquisition proposal; or



•

approve, endorse or recommend, or execute or enter into any letter of intent, agreement in principle, merger agreement, acquisition agreement or other similar agreement relating to any acquisition proposal.

12

Table of Contents

        We have also agreed that we will immediately cease and terminate any existing activities, discussions or negotiations with any persons that were conducted by us prior to the date of the merger agreement with respect to any acquisition proposal.

        Even though we have agreed to the provisions described above relating to the non-solicitation of acquisition proposals, our board of directors may:

•

take and disclose to our stockholders a position with respect to a tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act; or



•

make any disclosure to our stockholders, if, based on advice from outside counsel, our board of directors determines in good faith that failing to do so would be reasonably likely to violate its fiduciary duty under applicable laws.

        Furthermore, notwithstanding the foregoing restrictions with respect to acquisition proposals by third parties, at any time prior to obtaining stockholder approval and adoption of the merger agreement and the merger, we or our board of directors, directly or indirectly through advisors, agents or other intermediaries, may furnish information concerning our businesses, properties or assets to any person or group including furnishing nonpublic information pursuant to an appropriate confidentiality agreement, and may engage in discussions and negotiations with such person or group concerning an acquisition proposal if, and only if:

•

such person or group has, after the date of execution of the merger agreement, submitted an unsolicited acquisition proposal which our board of directors determines in good faith is reasonably likely to result in a superior proposal (as defined in the merger agreement and described below in the section captioned "The Merger Agreement—Definitions of Acquisition Proposal and Superior Proposal"); or



•

our board of directors determines in good faith, based upon advice of outside counsel, that failing to do so would be reasonably likely to violate its fiduciary duties to our stockholders under applicable laws.

        Additionally, we have agreed with Chemring that neither the special committee nor our board of directors may (i) withdraw or modify, or qualify in a manner adverse to Chemring the recommendation of the special committee and our board of directors of the merger agreement or the transactions contemplated thereby, or (ii) approve or recommend, or permit Hi-Shear to enter into, any letter of intent, memorandum of understanding, acquisition agreement or similar agreement constituting or relating to any acquisition proposal unless:

•

we have received an acquisition proposal that our board of directors determined in good faith, based on advice of outside counsel, constitutes a superior proposal; or



•

our board of directors has determined in good faith, based upon advice of outside counsel, that failing to take such action would be reasonably likely to constitute a breach of its fiduciary duties to our stockholders under applicable laws.

        We have agreed that we will immediately advise Chemring of any proposal or inquiry received by us with respect to any acquisition proposal.

        Conditions to Completion of the Merger.     The merger will be completed only if certain conditions are satisfied or waived, including the following:

•

holders of a majority of our common stock must approve and adopt the merger agreement and the merger;



•

no court or other legal or regulatory order or statute, rule or regulation restricts or prohibits the merger;

        Termination of the Merger Agreement.     The merger agreement may be terminated, and the merger may be abandoned at any time prior to the effective time of the merger, by mutual written consent of the parties to the merger agreement, or by either Chemring or us:

•

if the merger has not been completed by March 1, 2010, provided that this right to terminate the merger agreement is not available to a party whose breach of the merger agreement has been the cause of, or resulted in, the failure of the closing to occur on or before March 1, 2010; or



•

if any court of competent jurisdiction or other governmental authority has issued a judgment, order, injunction, rule or decree, or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated by the merger agreement and such judgment, order, injunction, rule, decree or other action shall have become final and non-appealable.

        The merger agreement may be terminated, and the merger may be abandoned at any time prior to the effective time, by Chemring if our board of directors or any committee thereof has:

        Termination Fee.     The merger agreement requires that we pay Chemring an aggregate termination fee of $4,000,000 if the merger agreement is terminated either:

•

by us or Chemring because the merger had not been completed by March 1, 2010 (A) due to a delay resulting solely from our actions or (B) and prior to stockholder approval having been obtained, an acquisition proposal had been publicly disclosed, announced, commenced, submitted or made, and was not withdrawn at least five business days prior to the date of the special meeting of our stockholders to consider and vote upon the proposal to approve and adopt the merger agreement and the merger;



•

by Chemring because we breached or failed to perform any of our representations, warranties or covenants contained in the merger agreement and such breach or failure to perform gave rise to the failure of a condition to Chemring's obligation to complete the transaction and we failed to cure such breach or failure within 45 days following delivery of written notice of the same;

and in the case of either of the above, within 12 months after the merger agreement is terminated, we enter into a definitive agreement with respect to an acquisition proposal;

THE SPECIAL MEETING

        We are furnishing this proxy statement to our stockholders as part of the solicitation of proxies by our board of directors for use at the special meeting, and at any adjournments or postponements of the special meeting.

Date, Time and Place

        We will hold the special meeting at 24225 Garnier Street, Torrance, California 90505-5355 at 2:00 p.m., local time, on November 19, 2009.

Purpose of Special Meeting

        At the special meeting, we will ask holders of our common stock to approve and adopt the merger agreement and the merger. Based, in part, on the unanimous recommendation of a special committee consisting of three independent directors, our board of directors has unanimously approved resolutions approving the merger agreement and the merger, determining that the merger agreement and the terms and conditions of the merger are fair, advisable and in the best interests of Hi-Shear and our stockholders and directing that the merger and the merger agreement be submitted for approval and adoption at a special meeting of our stockholders. Our board of directors unanimously recommends that all of our stockholders vote FOR the approval and adoption of the merger agreement and the merger.

        Our board of directors also unanimously recommends that our stockholders vote FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger.

Record Date; Stock Entitled to Vote; Quorum

        Only holders of record of our common stock at the close of business on October 9, 2009, which is the record date for the special meeting, are entitled to notice of and to vote at the special meeting. As of the record date, 6,855,791 shares of our common stock were issued and outstanding and held by approximately 1,683 holders of record. A quorum will be present at the special meeting if a majority of the shares of our common stock issued and outstanding and entitled to vote on the record date are represented in person or by proxy at the special meeting. Shares of our common stock represented at the special meeting but not voting, including shares of our common stock for which proxies have been received but for which stockholders have abstained, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business at the special meeting. Our bylaws provide that the holders of a majority of the shares of stock entitled to vote who are present in person or represented by proxy at the meeting have the power to adjourn the meeting, without notice other than the announcement at the meeting. However, if the adjournment is to a date that is more than 30 days after the original meeting date, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting must be given to each stockholder of record entitled to vote at the meeting.

Votes Required

        The proposal to approve and adopt the merger agreement and the merger requires the affirmative vote of the holders of a majority of the shares of our common stock issued and outstanding on the record date. If a holder of our common stock abstains from voting or does not vote, either in person or by proxy, it will have the effect of a vote against the merger proposal. If you hold your shares in "street name" through a broker, bank or other nominee, you must direct your broker, bank or other nominee

16

Table of Contents

to vote in accordance with the instructions you have received from your broker, bank or other nominee. Brokers, banks or other nominees who hold shares of our common stock in street name for customers who are the beneficial owners of those shares may not give a proxy to vote those customers' shares in the absence of specific instructions from those customers. These non-voted shares will have the effect of votes against the approval and adoption of the merger agreement and the merger.

        The proposal to approve any adjournments of the special meeting, if determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger, requires the affirmative vote of a majority of the shares of our common stock represented in person or by proxy at the special meeting, even if less than a quorum. Accordingly, not voting at the special meeting will have no effect on the outcome of this proposal, but abstentions will have the effect of a vote against this proposal. Holders of record of our common stock on the record date are entitled to one vote per share on each matter to be considered at the special meeting.

        As of the record date, directors and executive officers of Hi-Shear, and their affiliates, had the right to vote 2,488,544 shares of Hi-Shear common stock, or 36.3% of the issued and outstanding Hi-Shear common stock at that date. In connection with the transactions contemplated by the merger agreement, George W. Trahan, our Chairman, Chief Executive Officer and President, entered into a stockholder agreement with Chemring and Merger Sub pursuant to which Mr. Trahan granted Chemring an irrevocable proxy to vote certain of his shares of Hi-Shear common stock comprising approximately 32.4% of Hi-Shear's issued and outstanding common stock as of the record date, in favor of the merger agreement and the merger. Mr. Trahan also granted an irrevocable proxy to Thomas Mooney pursuant to the Buy-Sell and Voting Agreement and Irrevocable Proxy dated March 3, 2000, which provides that the Mooney Family Trust is entitled to vote one-half of the excess shares of Hi-Shear common stock beneficially owned by Mr. Trahan over the number of shares of Hi-Shear owned by the Mooney Family Trust. As of the record date, the Mooney Family Trust is entitled to vote approximately 247,719 of Mr. Trahan's shares of Hi-Shear common stock at the special meeting. The Mooney Family Trust is not entitled to vote any of the shares of common stock owned by Mr. Trahan as to which Mr. Trahan has granted a proxy to Chemring pursuant to the stockholder agreement described above.

Voting of Proxies

        All shares represented by properly executed proxies received in time for the special meeting will be voted at the special meeting in the manner specified by the holders thereof. Properly executed proxies that do not contain voting instructions will be voted FOR the approval and adoption of the merger agreement and the merger and FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger. No proxy that is specifically marked AGAINST approval and adoption of the merger agreement and the merger will be voted in favor of the adjournment proposal, unless it is specifically marked FOR the proposal to adjourn the special meeting to a later date.

        Pursuant to Delaware law and our bylaws, no matter other than the proposals to approve and adopt the merger agreement and the merger and to adjourn the meeting, if determined to be necessary by Hi-Shear, will be brought before the special meeting.

Revocability of Proxies

        The grant of a proxy on the enclosed form of proxy does not preclude a stockholder from voting in person at the special meeting. A stockholder may revoke a proxy at any time prior to its exercise by:

•

filing with our Secretary a duly executed revocation of proxy;



•

submitting a duly executed proxy to our Secretary bearing a later date; or



•

appearing at the special meeting and voting in person; however, attendance at the special meeting will not in and of itself constitute revocation of a proxy.

        If you have instructed your broker to vote your shares, you must follow directions received from your broker to change these instructions.

        Hi-Shear stockholders who require assistance should contact the persons at the address or phone number provided on page 5 of this proxy statement.

Solicitation of Proxies

        All costs related to the solicitation of proxies, including the printing and mailing of this proxy statement, will be borne by us. We have retained MacKenzie Partners, Inc. to aid in the solicitation of proxies and to verify records relating to the solicitation. MacKenzie Partners, Inc. will receive a fee for its services of $8,500 and reimbursement for reasonable out-of-pocket expenses. In addition, our directors, officers and employees may, without additional compensation, solicit proxies from stockholders by mail, telephone, facsimile, or in person. However, you should be aware that certain members of our board of directors and our officers have interests in the merger that are different from, or in addition to, yours. See "The Merger—Interests of Hi-Shear's Executive Officers and Directors in the Merger."

        To the extent necessary in order to ensure sufficient representation at the special meeting, Hi-Shear may request the return of proxy cards by telecopy. The extent to which these proxy soliciting efforts will be necessary depends entirely upon how promptly proxies are received. You should send in your proxy by mail without delay. We will also reimburse brokers and other custodians, nominees and fiduciaries for their expenses in sending these materials to you and getting your voting instructions.

Stock Certificates

        Stockholders should not send stock certificates with their proxies. A letter of transmittal with instructions for the surrender of our common stock certificates will be mailed to our stockholders as soon as practicable after completion of the merger.

THE MERGER
(Proposal 1)

Description of the Merger

        Based, in part, on the unanimous recommendation of a special committee consisting of three independent directors, the board of directors of Hi-Shear has unanimously approved a merger agreement and a merger whereby Hi-Shear will become a wholly-owned direct or indirect subsidiary of Chemring upon completion of the merger. If the merger agreement and the merger are approved and adopted by Hi-Shear stockholders, Merger Sub, a newly-formed merger subsidiary of Chemring will be merged with and into Hi-Shear, and Hi-Shear will be the surviving company in the merger. We strongly encourage you to read carefully the merger agreement in its entirety, a copy of which is attached as Annex A to this proxy statement, because it is the legal document that governs the merger.

        If the merger is completed, you will receive the cash merger consideration of $19.18, without interest and less applicable withholding taxes, in exchange for each share of Hi-Shear common stock that you own at the effective time of the merger.

        After the merger is completed, you will have the right to receive the merger consideration but you will no longer have any rights as a stockholder of Hi-Shear. You will receive your portion of the merger consideration after exchanging your stock certificates representing our common stock in accordance with the instructions contained in a letter of transmittal to be sent to you shortly after completion of the merger.

        Hi-Shear common stock is currently registered under the Exchange Act and is designated for trading on the NYSE Amex under the symbol "HSR." Following the merger, Hi-Shear common stock will be delisted from the NYSE Amex and will no longer be publicly traded, and the registration of Hi-Shear common stock under the Exchange Act will be terminated.

        Please see "The Merger Agreement" for additional and more detailed information regarding the merger agreement.

Background of the Merger

        The board of directors and management of Hi-Shear have continually engaged in a review of Hi-Shear's business plans and other strategic opportunities, including the evaluation of the market in which Hi-Shear competes, the possibility of pursuing strategic alternatives, such as acquisitions, and the possible sale of Hi-Shear, each with the view towards maximizing stockholder value.

        On November 18, 2008, our board of directors met at a special meeting of the board of directors. In light of the topics to be discussed, a representative of Gibson, Dunn & Crutcher LLP ("Gibson Dunn") was invited to participate in the meeting. At this meeting, George W. Trahan, Hi-Shear's Chairman, Chief Executive Officer and President, provided our board of directors with a general update on Hi-Shear's business and outlook. Mr. Trahan discussed in detail the opportunities and risks that Hi-Shear may face in light of the national banking crisis, capital availability and the new administration's approach to defense spending. Mr. Trahan informed our board of directors that he was confident about the fundamentals of Hi-Shear's business and Hi-Shear's near term prospects and outlook but also discussed the challenges that Hi-Shear faced as a small independent company. Mr. Trahan highlighted the difficulties of remaining an independent company in its industry and the challenges that Hi-Shear will face in the future in light of the greater capital resources of some of its competitors. Mr. Trahan provided examples of competitors with greater resources who were attempting to more aggressively compete with Hi-Shear, and noted that although they had been unsuccessful in taking Hi-Shear's market share to date, it was one of the risks that Hi-Shear faces if it remains a stand-alone company with limited capital resources. Our board of directors discussed the potential parties that may be interested in pursuing a strategic transaction with Hi-Shear, as well as financial advisors

that had sufficient experience in the aerospace and defense industry to assist Hi-Shear in a potential sale process. Gibson Dunn then led a discussion relating to the fiduciary duties of our board of directors under Delaware law in connection with the evaluation of potential strategic transactions.

        In light of the significant share holdings of board members Mr. Trahan and Mr. Thomas Mooney, Gibson Dunn recommended that our board of directors form a special committee of our board of directors to further evaluate whether a strategic transaction was in the best interests of Hi-Shear and its stockholders. Our board of directors determined to form a special committee in order to explore whether a strategic transaction was in the best interests of Hi-Shear and its stockholders, to negotiate the terms and conditions of such a transaction and to take other actions in connection with such a transaction on behalf of our board of directors, and appointed Mr. Jack Bunis as Chairman of the special committee and Mr. Lawrence Moreau and Mr. John Zaepfel to also serve on the special committee. Messrs. Bunis, Moreau and Zaepfel are all independent directors.

        On November 18, 2008, immediately following the meeting of our board of directors, the special committee met to discuss the advantages and disadvantages of exploring a potential strategic transaction and determined to proceed to gather information about whether to pursue such a transaction. In connection with this determination, the special committee asked Mr. Bunis to propose a slate of financial advisors for the special committee to interview. At this meeting, the special committee resolved to retain Gibson Dunn as counsel to the special committee.

        On December 5, 2008, the special committee held a telephonic meeting. A representative of Gibson Dunn was present at the meeting. At the meeting, Mr. Bunis updated the special committee on his search for the most qualified investment bank to retain as financial advisor to the special committee and the special committee discussed the appropriate criteria to use in selecting a financial advisor. Mr. Bunis recommended that the special committee consider a minimum of five investment banks in connection with the process of selecting the special committee's financial advisor.

        On December 19, 2008, the special committee held a meeting in order to interview several investment banking firms chosen to make presentations to the special committee in connection with the exploration of potential strategic transactions. A representative of Gibson Dunn was present at the meeting. After the conclusion of the presentations, the special committee discussed the merits of each presentation and determined to hold a meeting in early January 2009 to finalize their thoughts on the selection process.

        On January 12, 2009, the special committee held a telephonic meeting at which it decided to invite two of investment banks to make an additional presentation to the special committee in connection with the exploration of a potential strategic transaction. A representative of Gibson Dunn was present at the meeting.

        On February 3, 2009, the special committee held a meeting at which Mr. Trahan and a representative of Gibson Dunn were present. At this meeting, Gibson Dunn gave a presentation detailing the special committee's fiduciary duties in the context of exploring a strategic transaction. The two investment banks chosen to give additional presentations to the special committee were then given an opportunity make their presentations. A third investment bank was also invited to make a presentation at this meeting.

        On February 5, 2009, the special committee held a telephonic meeting at which the members of the special committee discussed the presentations given by the investment banks chosen to present to our board of directors. A representative of Gibson Dunn was present at the meeting. After discussion and deliberation, the special committee directed Gibson Dunn to begin negotiating an engagement with Lazard and asked Gibson Dunn to report back on its progress.

        On February 8, 2009, the special committee held a telephonic meeting at which a representative of Gibson Dunn was present, to review the terms of the fee proposal from Lazard. The special committee

20

discussed the fee proposal from Lazard and directed Gibson Dunn to further negotiate certain terms of the proposal, including negotiating an incentive-based fee that would create an incentive for Lazard to seek the highest price possible for Hi-Shear, and to report back to the special committee.

        On February 13, 2009, the special committee held a telephonic meeting at which a representative of Gibson Dunn was present. The special committee discussed in detail the terms of the proposed engagement of Lazard and approved the engagement of Lazard to act as the special committee's financial advisor in connection with the exploration of a potential strategic transaction. The special committee then discussed with Gibson Dunn the next steps in the process.

        On February 19, 2009, the special committee entered into a formal engagement letter with Lazard to act as its financial advisor in connection with the exploration of a potential strategic transaction.

        Following its engagement, as contemplated by its engagement letter, Lazard consulted with members of the special committee and Hi-Shear management to identify parties that may have an interest in a strategic transaction with Hi-Shear, developed preliminary procedures and timetables for implementing a strategic transaction and assisted Hi-Shear management in the preparation of certain written materials describing Hi-Shear.

        Between May 8, 2009 and June 3, 2009, Lazard contacted 71 potential buyers of which 44 were strategic acquirors and 27 were financial sponsors.

        Between May 12, 2009 and June 10, 2009, the special committee entered into non-disclosure agreements with 30 potential acquirors, including 18 financial sponsors and 12 strategic acquirors.

        On May 20, 2009, Lazard began distribution of a confidential information memorandum to each of the potential acquirors and a letter containing bid instructions. The bid instruction letter requested that interested parties submit preliminary indications of interest to Lazard on or before June 9, 2009.

        On June 9, 2009 and June 10, 2009, Lazard received 12 preliminary indications of interest from six financial sponsors and six strategic acquirors.

        On June 11, 2009, the special committee held a telephonic meeting with Mr. Trahan and representatives of Lazard and Gibson Dunn present. At this meeting, representatives of Lazard presented to the special committee the details of the 12 initial indications of interest received from participants in the auction process and fielded questions from the special committee regarding the various proposals. The special committee decided to take some time to give additional consideration to the indications of interest and to reconvene later in the day for further review and discussion.

        Later in the day on June 11, 2009, the special committee reconvened a telephonic meeting at which Mr. Trahan and representatives of Lazard and Gibson Dunn were again present. At the meeting, representatives of Lazard briefly reviewed the discussions held earlier in the day with the special committee. Representatives of Gibson Dunn reviewed with the special committee its fiduciary duties with respect to its evaluation of the indications of interest.

        After further discussion and consideration of the indications of interest, the special committee resolved to invite five of the strategic acquirors, including Chemring, to participate in the next round of the auction. These five parties were chosen due to the generally higher valuations these potential acquirors were willing to pay and each such party's ability to fund the acquisition with cash or existing loan facilities. The special committee then discussed, among other things, its proposed response to each of these five bidders, and Lazard discussed potential strategies to maximize stockholder value. At the conclusion of this discussion, the special committee instructed Lazard to provide these parties with access to an online due diligence data room and to arrange for each such party to attend a management presentation. The special committee also instructed Lazard to inform the other seven bidders that their bids were not sufficient to move forward in the process at that time, but that Lazard would be in contact with them if anything changed.

        Representatives of Lazard then discussed generally the timing and process by which the next stages of the auction process would be conducted and when the bidders participating in the next round of the auction would be invited to submit "best and final" bids. The special committee and representatives of Lazard and Gibson Dunn discussed establishing the second deadline for the "best and final" bids to occur some time in early August 2009.

        On June 22, 2009, an additional financial sponsor submitted a preliminary indication of interest. Because the price that this potential acquiror was willing to pay was significantly lower than the bidders chosen to move forward in the process, the special committee determined not to invite this party into the next round of the auction process.

        Between June 23, 2009 and July 1, 2009, each of the five remaining participants in the auction process attended in-person presentations of Hi-Shear's management.

        On July 10, 2009, a draft merger agreement prepared by Gibson Dunn pursuant to which a potential transaction would be consummated was distributed to each of the five participants in this stage of the auction process.

        On July 13, 2009, Lazard contacted an additional strategic acquiror ("Bidder D") to inquire as to whether it would be interested in participating in the auction process. This party was not previously contacted due to an ongoing dispute between Hi-Shear and affiliates of this party. However, due to settlement of the dispute and because of its perceived potential interest in acquiring Hi-Shear and the party's financial resources, the special committee instructed Lazard to admit this potential acquiror into the process.

        On July 14, 2009, the special committee held a telephonic meeting with representatives of Gibson Dunn and Lazard. At the meeting, representatives of Lazard presented an update on the progress of the auction process, including updates on the success of the management presentations, the status of the due diligence process of each participant and Lazard's overall impressions on which bidders were likely to submit competitive "best and final" bids. The special committee determined that the next meeting of the special committee would take place shortly after the bid deadline of August 3, 2009, at which meeting an evaluation of the "best and final" bids would occur.

        On July 29, 2009, in order to allow the remaining bidders additional time to complete their financial analyses and due diligence, the final bid deadline was extended until August 7, 2009.

        On August 7, 2009, two bidders, Chemring and another bidder ("Bidder B"), submitted "best and final" bids. These bids were distributed to the members of the special committee and a meeting of the special committee to discuss the final bids was set for August 10, 2009. On the morning of the next business day, August 10, 2009, a third "best and final" bid was submitted to Lazard by another of the remaining bidders ("Bidder C") and distributed by Lazard to the members of the special committee.

        On August 10, 2009, the special committee held a meeting with Mr. Trahan and representatives of Lazard and Gibson Dunn in attendance to discuss the "best and final" bids received by Lazard. Representatives of Lazard made a presentation to the special committee regarding the three bidders that submitted "best and final" bids. Chemring submitted a non-binding written bid to purchase all of the outstanding stock of Hi-Shear for an aggregate purchase price of $128.7 million in the aggregate for all outstanding shares of Hi-Shear, representing approximately $18.78 per share. All three of the bids included a markup of the merger agreement. Lazard noted that it had spoken with Chemring and Bidder B after each had submitted its final bid to inquire whether either party was willing to increase its bid. Representatives of Lazard then discussed the financial aspects of each "best and final" bid with the special committee and responded to questions from the special committee members. Representatives of Gibson Dunn discussed legal issues relating to the bidders' responses to the draft merger agreement. After discussion, the special committee instructed Lazard to go back to each of the bidders to confirm certain aspects of their proposals and to inquire whether they were willing to

22

increase their respective aggregate purchase prices and to report back to the special committee on the outcome of those discussions. The special committee indicated to Lazard and Gibson Dunn that, if Chemring would be willing to increase its bid and was the highest bidder, the special committee would consider entering into a short exclusivity period with Chemring in light of the combination of its bid, the lack of financing condition in its offer and the generally favorable terms of its responses to the terms of the draft merger agreement. The special committee instructed Gibson Dunn to negotiate the terms of the merger agreement with the ultimate high bidder.

        On August 11, 2009, Lazard contacted the final bidders, including Chemring to confirm various terms of their respective proposals and determine if there was any willingness to increase their bids.

        Also on August 11, 2009, Lazard received a preliminary indication of interest from Bidder D. The aggregate purchase price Bidder D appeared to be willing to pay was lower than the offer submitted by Chemring and was less definitive than the other bids. As a result, Bidder D's participation in the auction process was put on hold pending the outcome of the discussions with Chemring, Bidder B and Bidder C.

        On August 12, 2009, Lazard received a revised proposal from Chemring indicating that Chemring was willing to increase its bid to pay $131.8 million in the aggregate for all of the outstanding shares of Hi-Shear, representing $19.15 per share. The $19.15 per share bid was higher than the "best and final" offers received from Bidder B and Bidder C. In connection with their increased bid, Chemring requested that they receive an exclusivity period until September 11, 2009.

        On August 17, 2009, the special committee, on behalf of Hi-Shear, entered into an exclusivity agreement with Chemring that provided that the special committee would negotiate exclusively with Chemring until September 11, 2009.

        From August 17, 2009 through September 15, 2009, representatives of Lazard and Gibson Dunn, in conjunction with management and Mr. Bunis, worked with Chemring management and its outside corporate counsel, Seyfarth Shaw LLP ("Seyfarth"), to facilitate Chemring's due diligence process.

        On August 19, 2009, a representative of Gibson Dunn and Seyfarth participated in telephonic negotiations regarding the key issues presented by Chemring's markup of the merger agreement submitted by Chemring with its "best and final" bid.

        On August 21, 2009, representatives of Gibson Dunn and Seyfarth participated in further more detailed telephonic negotiations regarding the markup of the merger agreement.

        On August 31, 2009, Messrs. Bunis and Trahan spoke via teleconference with representatives of Gibson Dunn regarding various provisions of the merger agreement. Later in the day on August 31, 2009, Messrs. Bunis and Trahan had further telephonic discussions with representatives of Gibson Dunn and Lazard regarding the merger agreement.

        On the evening of August 31, 2009, representatives of Gibson Dunn forwarded a revised merger agreement to representatives of Seyfarth and Chemring containing revisions to the draft of the merger agreement that Chemring submitted with its "best and final" bid.

        On September 2, 2009, representatives of Chemring and Seyfarth traveled to Los Angeles to meet with Mr. Bunis and representatives of Lazard and Gibson Dunn to negotiate various provisions of the merger agreement, including the aggregate purchase price offered by Chemring. During this meeting, the parties decided that it was advantageous to extend the exclusivity period until September 15, 2009.

        From September 3, 2009 until the signing of the definitive merger agreement on September 15, 2009, Mr. Bunis and representatives of Lazard and Gibson Dunn negotiated various provisions of the merger agreement, including the aggregate purchase price offered by Chemring, with Chemring.

Representatives of Gibson Dunn and Seyfarth also continued to negotiate and exchange drafts of the merger agreement and the related disclosure schedules.

        On September 15, 2009, the special committee convened a meeting to consider whether the terms of the merger agreement and transactions contemplated thereby, including the merger, were advisable, fair and in the best interests of Hi-Shear stockholders and whether to recommend to our board of directors that our board of directors approve and adopt the merger, the merger agreement and the transactions contemplated thereby. Representatives of Gibson Dunn and Lazard were present at the meeting. Mr. Trahan was also initially present at this meeting.

        Representatives of Lazard reviewed with the special committee the auction process undertaken and the process of negotiating the merger agreement and the purchase price with Chemring. A representative of Gibson Dunn reviewed with the special committee the significant terms of the merger agreement and the steps and timing going forward should the special committee and our board of directors approve entry by Hi-Shear into the merger agreement.

        Representatives of Lazard then reviewed Lazard's financial analysis and rendered its oral opinion to the special committee, which opinion was subsequently confirmed in writing, that as of September 15, 2009, based upon and subject to the various factors, assumptions, procedures, limitations and qualifications set forth in such written opinion, the consideration, as understood by Lazard on September 15, 2009, of $19.15 for each outstanding share of Hi-Shear common stock to be received by stockholders of Hi-Shear pursuant to the merger was fair from a financial point of view to such holders (the full text of that opinion, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Lazard in connection with its opinion, is attached as Annex B to this proxy statement and should be read in its entirety in conjunction with the information contained in "The Merger—Financial Advisor's Opinion Regarding the Merger Consideration").

        Following these discussions and presentations, Mr. Trahan was excused from the meeting. After further discussion and careful consideration, the special committee unanimously determined that the merger was advisable, fair and in the best interests of Hi-Shear stockholders, and recommended to our board of directors that our board of directors approve and adopt the merger, the merger agreement and the transactions contemplated thereby.

        Immediately after the special committee meeting, our board of directors convened a meeting to consider whether to approve the merger agreement and transactions contemplated thereunder. After careful consideration, and on the unanimous recommendation of the special committee, our board of directors unanimously concluded that the merger and the other transactions contemplated by the merger agreement were advisable, fair and in the best interests of Hi-Shear stockholders, and that the executive officers were authorized and directed to submit the merger agreement and the transactions contemplated thereby to Hi-Shear stockholders for their approval. Our board of directors also authorized Mr. Bunis, Mr. Trahan, Lazard and Gibson Dunn to continue to negotiate the final terms of the merger agreement, including to see whether they could further increase the price.

        After the special committee and board meetings, on account of a correction in the total transaction consideration that Chemring had agreed to pay, the price per share was increased from $19.15 to $19.18. Representatives of Lazard then updated their fairness opinion to provide that the consideration of $19.18 for each outstanding share of Hi-Shear common stock to be received by stockholders of Hi-Shear pursuant to the merger was fair from a financial point of view to such holders (the full text of that opinion, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Lazard in connection with its opinion, is attached as Annex B to this proxy statement and should be read in its entirety in conjunction with the information contained in "The Merger—Financial Advisor's Opinion Regarding the Merger Consideration").

        Late in the evening on September 15, 2009 in Los Angeles and early in the morning on September 16, 2009 in the United Kingdom, the merger agreement was executed by Hi-Shear, Merger Sub and Chemring. On September 16, 2009, each of Chemring and Hi-Shear issued a press release announcing entry by Chemring and Hi-Shear into the definitive merger agreement.

Reasons for the Merger

        At the meeting of the special committee consisting of three independent directors held on September 15, 2009, the special committee unanimously resolved to recommend that our board of directors approve the merger with Chemring. At the meeting of our board of directors on the same date, our board of directors received the special committee's recommendation and determined to accept that recommendation, and to approve the merger with Chemring and recommend it to Hi-Shear stockholders. See "The Merger—Background of the Merger" and "The Merger—Hi-Shear Board of Directors' Recommendation."

        In making its determination and recommendation set forth above, the special committee considered, among other things:

•

its knowledge of the current state of our business, including our financial condition, operations, business plans, management, competitive position and prospects;



•

its familiarity with the challenges that Hi-Shear faces as a "micro-cap" thinly traded public company and a smaller company than many of our competitors in the aerospace and defense industry, as discussed in "The Merger—Background of the Merger";



•

its increasing costs and burden of compliance with the U.S. public company regulatory regime; and



•

its belief, based on its knowledge of, among other things, the matters enumerated above, that our shares were unlikely to trade at prices substantially above their pre-merger announcement price for a significant period.

        The special committee also considered, among other things, its knowledge of the process that it had closely supervised—through formal meetings, informal consultation, regular advice from legal and financial advisers and the continuous interaction between its chairman and those advisers—to investigate potential transactions and ultimately negotiate the merger agreement with Chemring, as described under "The Merger—Background of the Merger," including:

•

the substantial number of sophisticated and knowledgeable potential buyers (including 27 potential financial sponsors and 45 potential strategic acquirors) contacted by Lazard at the direction of the special committee to ascertain potential interest in acquiring Hi-Shear and the criteria for the selection of those third parties by the special committee;



•

the number of those potential buyers that had signed confidentiality agreements and received information about Hi-Shear, engaged in a due diligence investigation of us, submitted preliminary indications of interest and submitted definitive acquisition proposals;



•

the fact that 14 of the 72 third parties on the potential buyer list had submitted preliminary indications and Chemring and two additional third-parties had submitted a final proposal; and



•

the fact that Chemring's bid was the highest of the bids.

Table of Contents

        In the course of its deliberations, the special committee also considered, among other things, the following material positive factors regarding the merger:

•

the fact that the $19.18 per share merger consideration to be received by Hi-Shear stockholders represented a premium of approximately 61.4% over the closing price per share as reported on the NYSE Amex on September 15, 2009 (which was the date the special committee recommended to our board of directors, and our board of directors unanimously approved, the merger agreement with Chemring);



•

the opinion of Lazard to the special committee and our board of directors to the effect that, as of September 15, 2009, and based upon and subject to the assumptions, qualifications and limitations set forth in its written opinion of that date, the merger price of $19.18 per share in cash to be received by Hi-Shear stockholders pursuant to the merger agreement was fair, from a financial point of view, to such stockholders (the full text of Lazard's written opinion, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Lazard in connection with its opinion, is attached as Annex B to this proxy statement and should be read in its entirety in conjunction with the information contained in "The Merger—Financial Advisor's Opinion Regarding the Merger Consideration"), as well as the presentation Lazard made to the special committee on that date regarding the analyses performed in connection with its fairness opinion;



•

the fact that the merger consideration is all cash, which provides certainty of value to Hi-Shear stockholders compared to a transaction in which they would receive stock or other non-cash consideration;



•

the experience, reputation and financial capabilities of Chemring, including Chemring's knowledge of the markets that Hi-Shear serves and the belief that Hi-Shear's customers would benefit from the continued service of Hi-Shear's experienced employees post-acquisition;



•

the terms of the merger agreement, including the parties' representations, warranties and covenants, and the conditions to their respective obligations, which were negotiated on an arms-length basis and with the advice of legal and financial advisers;



•

the then current financial market conditions, and historical market prices, volatility and trading information with respect to our common stock, including the possibility that if we remained as an independent publicly-owned corporation, in the event of a decline in the market price of our common stock or the stock market in general, the price that might be received by holders of our common stock in the open market or in a future transaction might be less than the merger consideration;



•

historical and current information concerning our business, financial performance and condition, operations, technology, management and competitive position, and current industry, economic and market conditions, including our prospects, if we were to remain an independent company;



•

the likelihood that the merger will be consummated in light of the nature of the conditions to Chemring's obligation to complete the merger;



•

the absence of any financing condition to Chemring's obligation to consummate the merger;



•

the thin trading market and the relative lack of liquidity of Hi-Shear common stock, which would make it difficult for any large stockholder to sell its shares of common stock in the public market without depressing the market price of Hi-Shear common stock. The special committee and our board of directors believed that the proposed merger would permit all Hi-Shear stockholders to sell all of their shares at a significant premium to the recent trading price;

26

Table of Contents

•

the fact that the merger agreement and the transactions contemplated thereby were the product of extensive arms' length negotiations between representatives of Chemring and representatives of Hi-Shear;



•

the fact that appraisal rights would be available to Hi-Shear stockholders. For more information, see the section entitled "Appraisal Rights" beginning on page 10 of this proxy statement; and



•

the fact that the merger agreement permits our board of directors, where failing to do so would be reasonably likely to violate its fiduciary duties, to authorize us to participate in discussions and negotiations with, and furnish information to, third parties in connection with unsolicited bona fide written acquisition proposals and to change its recommendation in favor of the merger following receipt of a superior unsolicited bona fide written proposal for at least a majority of our issued and outstanding equity securities or 50% of our consolidated assets and, if our stockholders fail to approve and adopt the merger agreement, to potentially enter into a transaction with another acquirer, subject to the limitations described under "The Merger Agreement—Acquisition Proposals by Third Parties" and subject to the payment of a termination fee of $4,000,000 (such termination fee constituting approximately 3.0% of the aggregate merger consideration on a fully diluted basis).

        In the course of its deliberations, the special committee also considered, among other things, the following potentially negative factors regarding the merger:

•

the fact that Hi-Shear stockholders would not benefit from any potential future increase in our value beyond $19.18 per share;



•

the fact that gains from the sale of shares in the merger would be taxable to Hi-Shear stockholders for U.S. federal income tax purposes;



•

the restrictions that the merger agreement would impose on our ability to operate our business until the merger was completed or the merger agreement was terminated;



•

the possibility of disruption to our operations and personnel following the announcement of the execution of the merger agreement and the resulting potentially adverse effect on Hi-Shear if the merger were not to close;



•

the interests that our directors and our executive officers may have with respect to the merger in addition to their interests as stockholders generally, as described in "The Merger—Interests of Hi-Shear's Directors and Officers in the Merger;"



•

the fact that, under the merger agreement, our board of directors would not be entitled to terminate the merger agreement prior to March 1, 2010 in order to pursue a superior offer without paying Chemring the applicable termination fee; and



•

the fact that we may have to pay the $4,000,000 termination fee even if the merger agreement terminates pursuant to its terms on or after March 1, 2010, if, within 12 months thereafter, we enter into another transaction for the sale of more than a majority of our outstanding equity securities or 50% of our consolidated assets.

        The special committee concluded that these potentially negative factors were substantially outweighed by the opportunity presented by the merger for our stockholders to monetize their Hi-Shear investment for $19.18 per share in cash within a relatively short period of time if the merger conditions are satisfied, which the special committee believed would maximize the value of their shares and eliminate the risk that the inherent uncertainty affecting our future prospects and the financial markets as a whole could result in a diminution in the market value of their shares. Accordingly, the special committee concluded that the merger was in the best interests of our stockholders.

        In making its determination and recommendation set forth above, our board of directors considered the determination and recommendation of the special committee, having regard to the independence of its members, their business experience and their active role in overseeing, with the advice of experienced legal and financial advisors, the process of investigating potential transactions that led to the negotiation of the merger agreement with Chemring. In addition, our board of directors took into consideration that, while Mr. Trahan was not independent in the sense that he is the Chief Executive Officer and President of Hi-Shear, he is not affiliated with Chemring and that, as a significant Hi-Shear stockholder, his interests are generally aligned with Hi-Shear's stockholders as a whole. Our board of directors also took account of the same considerations, including the same material positive and potentially negative factors, that the special committee had considered and reached the same conclusion as the special committee with respect to the benefits of the merger for Hi-Shear stockholders.

        The preceding discussion of the factors considered by the special committee and our board of directors is not, and is not intended to be, exhaustive, but it does set forth the material factors considered. In light of the variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, neither the special committee nor our board of directors found it practicable to, and did not, quantify or otherwise attempt to assign relative weights to the various factors considered in reaching its determination, nor did it undertake to make any specific determination as to whether any particular factors (or any aspect of any particular factors) was favorable or unfavorable to its ultimate determination. Rather, each of the special committee and our board of directors reached its conclusion and recommendation based on its evaluation of the totality of the information presented, considered and analyzed. In considering the factors discussed above, individual directors may have ascribed differing significance to different factors.

Hi-Shear Board of Directors' Recommendation

        Upon the unanimous recommendation of the special committee consisting of three independent directors and after careful consideration, our board of directors has unanimously approved resolutions approving the merger and the merger agreement, determining that the merger agreement and the terms and conditions of the merger are fair, advisable and in the best interests of Hi-Shear and our stockholders and directing that the merger and the merger agreement be submitted for approval and adoption at a special meeting of our stockholders. Accordingly, our board of directors unanimously recommends that all of our stockholders vote FOR the approval and adoption of the merger agreement and the merger.

        Our board of directors also unanimously recommends that our stockholders vote FOR approval of adjournments of the special meeting, if determined to be necessary by Hi-Shear, to facilitate the approval and adoption of the merger agreement and the merger by permitting the solicitation of additional proxies if there are not sufficient votes at the time of the special meeting to approve and adopt the merger agreement and the merger. See "Adjournment of the Special Meeting (Proposal 2)."

Financial Advisor's Opinion Regarding the Merger Consideration

        Under an agreement dated February 19, 2009, the special committee retained Lazard to act as its investment banker. As part of this engagement, the special committee requested that Lazard evaluate the fairness, from a financial point of view, to Hi-Shear stockholders of the consideration to be received in the merger. Lazard has delivered to the special committee and our board of directors a written opinion dated September 15, 2009, that, as of that date, the consideration to be received in the merger by the holders of Hi-Shear common stock is fair, from a financial point of view, to the holders.

        The full text of the Lazard opinion is attached as Annex B to this proxy statement and is incorporated into this proxy statement by reference. The description of the Lazard opinion set forth in

this proxy statement is qualified in its entirety by reference to the full text of the Lazard opinion set forth in Annex B. Stockholders are urged to read the Lazard opinion in its entirety for a description of the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Lazard in connection with the opinion. Lazard's written opinion is directed to both the special committee and our board of directors and only addresses the fairness to the holders of Hi-Shear common stock of the consideration to be received in the merger from a financial point of view as of the date of the opinion. Lazard's written opinion does not address the merits of the underlying decision by Hi-Shear to engage in the merger or any other aspect of the merger and does not constitute a recommendation to any stockholder as to how the stockholder should vote on any matter relating to the merger. Lazard was not engaged by the special committee to, and did not, recommend the amount of consideration to be received in the merger. Lazard's opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Lazard as of, the date of the Lazard opinion. Lazard assumes no responsibility for updating or revising its opinion based on circumstances or events occurring after the date of the opinion. The following is only a summary of the Lazard opinion. You are urged to read the entire opinion.

        In the course of performing its review and analyses in rendering its opinion, Lazard:

•

analyzed certain historical business and financial information relating to Hi-Shear;



•

reviewed certain financial forecasts and other data provided by Hi-Shear relating to its businesses;



•

held discussions with members of the senior management of Hi-Shear with respect to the businesses and prospects of Hi-Shear and its strategic objectives;



•

reviewed public information with respect to certain other companies in lines of businesses Lazard believed to be generally comparable to the businesses of Hi-Shear;



•

reviewed the financial terms of certain business combinations involving the aerospace and defense and other industries generally;



•

reviewed the historical stock prices and trading volumes of Hi-Shear common stock; and



•

conducted such other financial studies, analyses and investigations as Lazard deemed appropriate.

        Lazard relied upon the accuracy and completeness of such information, and did not assume any responsibility for any independent verification of the foregoing information or any independent valuation or appraisal of any of the assets or liabilities of Hi-Shear, or concerning the solvency or fair value of Hi-Shear.

        With respect to financial forecasts, Lazard assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and judgments of management of Hi-Shear as to the future financial performance of Hi-Shear. Hi-Shear does not publicly disclose internal management financial forecasts of the type provided to Lazard for its evaluation analysis, and such financial forecasts were not prepared with a view towards public disclosure. These financial forecasts were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of management, including, without limitation, factors related to general economic and competitive conditions. Lazard assumed no responsibility for and expressed no view as to such forecasts or the assumptions on which they were based.

        Lazard noted that its opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to them as of, the date of the opinion. Lazard assumed no responsibility for updating or revising its opinion based on circumstances or events occurring after the date of the opinion. In rendering its opinion, Lazard assumed that the merger

would be consummated on the terms described in the merger agreement reviewed by Lazard, without any waiver of any material terms or conditions by Hi-Shear, and that obtaining the necessary regulatory approvals for the merger would not have an adverse effect on Hi-Shear. Lazard did not express any opinion as to any tax or other consequences that might result from the merger. Neither did Lazard's opinion address any legal, tax or accounting matters, as to which Lazard understood that the special committee and our board of directors obtained such advice as it deemed necessary from qualified professionals. Lazard's opinion did not address the merits of the underlying decision by Hi-Shear to engage in the merger and is not intended to constitute a recommendation to any stockholder of Hi-Shear as to how such holder should vote with respect to the merger or any matter relating thereto.

        The following is a brief transaction summary, along with material financial and comparative analyses, which Lazard deemed to be appropriate for this type of transaction and that were performed by Lazard in connection with rendering its opinion. These analyses included comparable public companies trading multiples, precedent transactions and discounted cash flow analyses. Lazard also performed several other analyses, including leveraged buyout and premiums paid for selected M&A transactions, for representative purposes only which were not directly considered as part of the evaluation.

        Transaction Overview.     Based upon the approximately 6.9 million fully-diluted shares of Hi-Shear common stock that were outstanding as of September 1, 2009 on a fully diluted basis (calculated pursuant to the treasury stock method), Lazard noted that the merger consideration of $19.18 per share implied an equity value of approximately $132.0 million. With approximately ($2.4) million of net debt (as of May 31, 2009 adjusted for the $5.1 million dividend payment per the 8-K dated July 16, 2009), Lazard noted that the merger consideration implied an enterprise value of approximately $129.6 million. Lazard also noted that the merger consideration of $19.18 per share of Hi-Shear common stock represented:

•

a premium of 61.4% over the closing price per share of Hi-Shear common stock on September 15, 2009 of $11.88;



•

a premium of 94.9% over the 60-trading average price per share of Hi-Shear common stock as of September 15, 2009 of $9.84;



•

a premium of 211.9% over the lowest intra-day trading price per share of Hi-Shear common stock on April 1, 2009 of $6.15, which was the lowest trading price of Hi-Shear common stock during the 52-week period ending September 15, 2009; and



•

a premium of 35.5% over the highest intra-day trading price per share of Hi-Shear common stock on August 11, 2009 of $14.15, which was the highest trading price of Hi-Shear common stock during the 52-week period ending September 15, 2009.

        Comparable Public Company Trading Analysis.     Lazard performed an analysis of comparable public companies by calculating certain financial multiples for selected public companies in the aerospace and defense industry that Lazard determined to be reasonably comparable to Hi-Shear. These comparable companies were as follows and were chosen because they are publicly traded companies whose principal line of businesses, products and technologies and end-markets is most similar to that of Hi-Shear. These companies included Ametek Inc., Chemring Group PLC, Ducommun Inc., Esterline Technologies Corp., Kaman Corp., Moog Inc., Teledyne Technologies Inc., TransDigm Group Inc. and Triumph Group Inc. While the selected group of comparable companies represents a mix of comparable public companies that encompasses Hi-Shear's primary attributes, no company, independently or as part of a set, is identical to Hi-Shear. As a result, Lazard made assumptions on various factors, including the overall economy, industry and business and referenced when determining the appropriate reference range.

        Using publicly available information and the share price for the selected comparable companies as of September 15, 2009, Lazard's analysis included comparing enterprise value (i.e., market value of common equity based on a diluted number of shares outstanding plus total debt less cash and equivalents) as a multiple of LTM EBITDA (earnings before interest, taxes, depreciation and amortization for the last 12 months). The results of this analysis is summarized as follows:

COMPARABLE COMPANIES MULTIPLES

        Using a reference range of 7.0x to 8.0x Hi-Shear's LTM EBITDA of approximately $10.6 million for fiscal period ending May 31, 2009, Lazard calculated an implied enterprise value range for Hi-Shear equal to approximately $74.0 million to $84.6 million, then subtracted net debt of approximately ($2.4) million to determine an implied equity value range for Hi-Shear equal to approximately $76.4 million to $87.0 million. After accounting for the vesting of in-the-money stock options (calculated pursuant to the treasury stock method), this analysis indicated a range of implied shares prices of Hi-Shear common stock of approximately $11.11 to $12.64, compared to the merger consideration of $19.18 per share. This range of implied share prices of Hi-Shear common stock represents premiums/(discounts) of (6.5%) and 6.4%, respectively, to the closing price per share of Hi-Shear common stock on September 15, 2009 of $11.88.

        Precedent Transactions Analysis.     Lazard performed an analysis of precedent transactions by calculating certain financial multiples paid for the acquisition of targets since 2006 in the aerospace and defense industry that Lazard determined to be reasonably comparable to Hi-Shear. These precedent transactions were as listed below and were chosen because the acquisition targets represented companies whose principal line of businesses, products and technologies and end-markets are most similar to that of Hi-Shear. These include the following:

        While the selected group of precedent transactions represents a mix of comparable public companies that encompasses Hi-Shear's primary attributes, no acquisition target, independently or as a whole, is identical to Hi-Shear. As a result, Lazard made assumptions on various factors, including the overall economy, industry and business and referenced when determining the appropriate reference range.

Table of Contents

        Using publicly available information as of September 15, 2009, Lazard analyzed the 13 transactions previously listed, comparing enterprise value (i.e., total consideration plus total debt less cash and equivalents) as a multiple of LTM EBITDA (earnings before interest, taxes, depreciation and amortization for the last 12 months) and as a multiple of LTM EBIT (earnings before interest and taxes). Both LTM EBITDA and LTM EBIT multiples were considered as part of the analysis given the robust range of LTM EBIT multiples for the selected range of precedent transactions. The results of this analysis is summarized as follows:

        Using a reference range of 7.0x to 9.0x Hi-Shear's LTM EBITDA of approximately $10.6 million for fiscal period ending May 31, 2009, Lazard calculated an implied enterprise value range for Hi-Shear equal to approximately $74.0 million to $95.1 million, then subtracted net debt of approximately ($2.4) million to determine an implied equity value range for Hi-Shear equal to approximately $76.3 million to $97.4 million. After accounting for the vesting of in-the-money stock options (calculated pursuant to the treasury stock method), this analysis indicated a range of implied shares prices of Hi-Shear common stock of approximately $11.11 to $14.18, compared to the merger consideration of $19.18 per share of Hi-Shear common stock. This range of implied share prices of Hi-Shear common stock represents premiums/(discounts) of (6.5%) and 19.3%, respectively, to the closing price per share of Hi-Shear common stock on September 15, 2009 of $11.88.

        Using a reference range of 8.0x to 9.0x Hi-Shear's LTM EBIT of approximately $10.1 million for fiscal period ending May 31, 2009, Lazard calculated an implied enterprise value range for Hi-Shear equal to approximately $81.0 million to $91.1 million, then subtracted net debt of approximately ($2.4) million to determine an implied equity value range for Hi-Shear equal to approximately $83.3 million to $93.5 million. After accounting for the vesting of in-the-money stock options (calculated pursuant to the treasury stock method), this analysis indicated a range of implied shares prices of Hi-Shear common stock of approximately $12.13 to $13.60, compared to the merger consideration of $19.18 per share of Hi-Shear common stock. This range of implied share prices of Hi-Shear common stock represents premiums of 2.1% and 14.5%, respectively, to the closing price per share of Hi-Shear common stock on September 15, 2009 of $11.88.

        Discounted Cash Flow Analysis.     Using management projections, Lazard performed a discounted cash flow analysis valuing Hi-Shear based on the present value of projected unlevered free cash flow for 2010 to 2012 and the present value of the terminal value in 2012, discounted to May 31, 2009. The analysis assumed a range of terminal year exit multiples of EBITDA of 7.0x to 8.0x and a range of discount rates of 12.5% to 14.5%, based on estimates relating to the weighted average cost of capital. These assumptions imply perpetuity growth rates of 4.7% to 7.5%.

        Lazard calculated an implied enterprise value range for Hi-Shear equal to approximately $123.7 million to $145.6 million, then subtracted net debt of approximately ($2.4) million to determine an implied equity value range for Hi-Shear equal to approximately $126.0 million to $147.9 million. After accounting for the vesting of in-the-money stock options (calculated pursuant to the treasury stock method), this analysis indicated a range of implied shares prices of Hi-Shear common stock of approximately $18.31 to $21.48, compared to the merger consideration of $19.18 per share of Hi-Shear common stock.

        Lazard performed a variety of financial and comparative analyses solely for the purpose of providing its opinion to the special committee and our board of directors that the consideration to be received in the merger was fair, from a financial point of view, to Hi-Shear stockholders. The preparation of a fairness opinion involves various determinations as to the most appropriate and

relevant methods of financial analysis and the application of these methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to a partial analysis or summary description. Accordingly, notwithstanding the separate analyses summarized above, Lazard believes that its analyses must be considered as a whole, and that selecting portions of the analyses or factors considered by it, without considering all such factors or analyses, or attempting to ascribe relative weights to some or all such analyses and factors, could create an incomplete view of the evaluation process underlying the Lazard opinion.

        The estimates contained in these analyses and the valuation ranges resulting from any particular analysis do not necessarily indicate actual values or predict future results or values, which may be significantly more or less favorable than those suggested by these analyses. Lazard did not assign any specific weight to any of the analyses described above and did not draw any specific conclusions from or with regard to any one method of analysis. In addition, analyses relating to the value of the businesses or securities are not appraisals and do not reflect the prices at which the businesses or securities may actually be sold or the prices at which their securities may trade. As a result, these analyses and estimates are inherently subject to substantial uncertainty. No company or transaction used in any of the analyses is identical to Hi-Shear or the merger. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning financial and operating characteristics of Hi-Shear and other factors that could affect the public trading values or the announced transaction values, as the case may be, of Hi-Shear and the companies to which the comparison is being made. Lazard's opinion and financial analyses were not the only factors considered by the special committee and our board of directors in their evaluation of the merger and should not be viewed as determinative of the views of the special committee and our board of directors or our management. Lazard has consented to the inclusion of and references to its opinion in this proxy statement. Under the terms of Lazard's engagement, Hi-Shear has agreed to pay Lazard an aggregate fee of approximately $4.5 million. A portion of the fee was payable upon Lazard's retention as financial advisor to the special committee and upon the rendering of its fairness opinion. The remainder of the fee is payable upon consummation of the transaction. Hi-Shear has agreed to reimburse Lazard for travel and other out-of-pocket expenses incurred in performing its services, including the fees and expenses of its legal counsel. In addition, Hi-Shear agreed to indemnify Lazard against certain liabilities, including liabilities under the federal securities laws relating to or arising out of Lazard's engagement. Lazard is an internationally recognized investment banking firm and is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, leveraged buyouts and valuations for real estate, corporate and other purposes. In the ordinary course of its business, Lazard and its affiliates may from time to time effect transactions and hold securities, including derivative securities, of Hi-Shear for its own account and for the accounts of its customers, and, accordingly, may at any time hold a long or short position in such securities. Lazard was selected to act as investment banker to the special committee and our board of directors because of its expertise and its reputation in investment banking and mergers and acquisitions and its independence with respect to the merger and the transactions contemplated by the merger agreement.

Interests of Hi-Shear's Executive Officers and Directors in the Merger

        In considering the recommendation of our board of directors with respect to the merger agreement and merger, you should be aware that some of our executive officers and directors may have interests in the merger that are in addition to, or different from the interests of Hi-Shear stockholders generally. Our board of directors was aware of and considered these interests in approving the merger agreement and the merger.

        Merger Proceeds and Other Payments to Be Received by Directors and Executive Officers.     Each of our directors and executive officers holds shares of our common stock, restricted stock units and/or

in-the-money stock options to purchase shares of our common stock. Shares of our common stock will be exchanged for the right to receive $19.18 per share in cash as described in this proxy statement. Options will be cancelled in exchange for a cash payment for each underlying share equal to the difference between (1) the cash price of $19.18 to be paid with respect to our common stock in the merger and (2) the exercise price per share of the options, less applicable withholding taxes. Restricted stock units will be cancelled and converted into the right to receive $19.18 per share. See "The Merger Agreement—Equity Plans".

        The following table sets forth the approximate cash proceeds that each of our executive officers and directors will receive, less any applicable withholding taxes, at the completion of the merger on the basis of the shares of Hi-Shear common stock, restricted stock units and in-the-money options to purchase shares of Hi-Shear common stock that they held as of October 9, 2009:

        For additional information regarding the nature of each director's and executive officer's beneficial ownership of our share of common stock, please see the information below under the caption "Security Ownership of Certain Beneficial Owners and Management."

        Employment with Chemring.     Upon the consummation of the Merger, at Chemring's request, George W. Trahan has agreed to serve as President and Treasurer of the surviving corporation until the expiration of his pre-existing employment agreement on February 28, 2010, or until his earlier termination by Chemring. Mr. Trahan is not entitled to severance or continuing benefits under his employment agreement in the event that he is terminated, regardless of the reason for termination. In addition, Jan L. Hauhe will serve as the Chief Financial Officer and Secretary of the surviving corporation.

        Special Committee and Board of Director Fees.     The schedule of director fees previously approved by our board provides for payments of $2,500 for the committee chairman and $2,000 for the other special committee members for attendance in person at any special board or committee meeting and $2,000 for the committee chairman and $1,500 for the other special committee members for telephonic attendance at any such meeting.

        Indemnification of Directors and Officers.     For a period of six years after the effective time of the merger, Chemring will cause Hi-Shear, as the surviving corporation in the merger, to indemnify and hold harmless those persons serving as directors and officers of Hi-Shear prior to the effective time of the merger, to the fullest extent permitted under applicable law. Prior to the effective time of the merger, Hi-Shear shall purchase a six-year prepaid "tail policy" providing substantially equivalent benefits as the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by Hi-Shear with respect to matters arising on or before the effective time of the merger, covering without limitation the transactions contemplated by the merger agreement. Chemring

shall cause such policy to be maintained in full force and effect for its entire term and cause all obligations of Hi-Shear thereunder to be honored by the surviving corporation.

Appraisal Rights

        In connection with the merger, record holders of Hi-Shear common stock will be entitled to appraisal rights if certain procedures are complied with and the merger is completed. Under Section 262 of the DGCL ("Section 262"), in lieu of receiving the merger consideration, Hi-Shear stockholders whose appraisal rights are properly demanded and perfected and not withdrawn or lost are entitled to have the "fair value" of their shares of Hi-Shear common stock at the effective time of the merger, exclusive of any element of value arising from the accomplishment or expectation of the merger, judicially determined and paid to them in cash by complying with the provisions of Section 262.

        The following is a brief summary of Section 262, which sets forth the procedures for demanding statutory appraisal rights. This summary is qualified in its entirety by reference to Section 262, a copy of the text which is attached to this proxy statement as Annex C.

        A Hi-Shear stockholder who desires to exercise appraisal rights must (a) not vote in favor of the merger agreement and the merger and (b) deliver a written demand for appraisal of such stockholder's shares to the Secretary of Hi-Shear before the vote to approve and adopt the merger agreement and the merger at the special meeting.

        A demand for appraisal must be executed by or for the Hi-Shear stockholder of record, fully and correctly, as the stockholder's name appears on the certificates representing the shares of Hi-Shear common stock. If shares of Hi-Shear common stock are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, such demand must be executed by the fiduciary. If shares of Hi-Shear common stock are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by all joint owners. An authorized agent, including an agent of two or more joint owners, may execute the demand for appraisal for a Hi-Shear stockholder of record; however, the agent must identify the record owner and expressly disclose that, in exercising the demand, the agent is acting as agent for the record owner. In addition, the Hi-Shear stockholder must continuously hold the shares of record from the date of making the demand through the effective time of the merger.

        A record owner, such as a broker, who holds shares of Hi-Shear common stock as a nominee for others may exercise appraisal rights with respect to the shares held for all or less than all beneficial owners of shares of Hi-Shear common stock as to which the holder is the record owner. In that case, the written demand must set forth the number of shares of Hi-Shear common stock covered by the demand. Where the number of shares of Hi-Shear common stock is not expressly stated, the demand will be presumed to cover all shares of Hi-Shear common stock issued and outstanding in the name of the record owner.

        Beneficial owners who are not record owners and who intend to exercise appraisal rights should instruct the record owner to comply strictly with the statutory requirements with respect to the exercise of appraisal rights before the vote on the approval and adoption of the merger agreement and the merger at the special meeting. Hi-Shear stockholders with shares held in "street name" who desire appraisal rights with respect to those shares must take such actions as may be necessary to ensure that a timely and proper demand for appraisal is made by the record owners of the shares. Shares of Hi-Shear common stock held through brokerage firms, banks and other financial institutions are frequently deposited with and held of record in the name of a nominee of a central security depositary. Any Hi-Shear stockholder desiring appraisal rights with respect to such stockholder's shares held through a brokerage firm, bank or other financial institution is responsible for ensuring that the demand for appraisal is made by the record holder and should instruct such firm, bank or institution that the demand for appraisal must be made by the record holder of the shares, which might be the

35

---

Table of Contents

nominee of a central security depositary if the shares of Hi-Shear common stock have been so deposited.

        As required by Section 262, a demand for appraisal must be in writing and must reasonably inform Hi-Shear of the identity of the record holder (which might be a nominee as described above) and of such holder's intention to seek appraisal of such shares.

        Hi-Shear stockholders of record who elect to demand appraisal of their shares must mail or deliver their written demand to: Hi-Shear Technology Corporation, 24225 Garnier Street, Torrance, California 90505-5355, Attention: Secretary. The written demand for appraisal should specify the Hi-Shear stockholder's name and mailing address, the number of shares owned, and that the stockholder is demanding appraisal of such stockholder's shares. The written demand must be received by Hi-Shear prior to the special meeting. Neither voting (in person or by proxy) against, abstaining from voting on or failing to vote on the proposal to approve and adopt the merger agreement and the merger will alone suffice to constitute a written demand for appraisal within the meaning of Section 262.

        In addition, Hi-Shear stockholders exercising appraisal rights must not vote their shares of Hi-Shear common stock in favor of approval and adoption of the merger agreement and the merger. Because a proxy that does not contain voting instructions will, unless revoked, be voted in favor of approval and adoption of the merger agreement and the merger, a Hi-Shear stockholder who votes by proxy and who wishes to exercise appraisal rights must vote against the approval and adoption of the merger agreement and the merger or abstain from voting on the approval and adoption of the merger agreement and the merger.

        Within 120 days after the effective time of the merger, either the surviving corporation or any Hi-Shear stockholder who has timely and properly demanded appraisal of such stockholder's shares and who has complied with the required conditions of Section 262 and is otherwise entitled to appraisal rights may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares of Hi-Shear common stock of all Hi-Shear stockholders who have properly demanded appraisal. If a petition for an appraisal is timely filed, after a hearing on such petition, the Delaware Court of Chancery will determine which Hi-Shear stockholders are entitled to appraisal rights and thereafter will appraise the shares owned by those stockholders, determining the fair value of the shares of Hi-Shear common stock exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest to be paid, if any, upon the amount determined to be the fair value. In determining fair value, the Delaware Court of Chancery is to take into account all relevant factors. In Weinberger v. UOP, Inc., et al. , the Delaware Supreme Court discussed the considerations that could be considered in determining fair value in an appraisal proceeding, stating that "proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court" should be considered and that "[f]air price obviously requires consideration of all relevant factors involving the value of a company." The Delaware Supreme Court stated that in making this determination of fair value the court must consider "market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which were known or which could be ascertained as of the date of merger which throw any light on future prospects of the merged corporation." The Delaware Supreme Court construed Section 262 to mean that "elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered." However, the Delaware Supreme Court noted that Section 262 provides that fair value is to be determined "exclusive of any element of value arising from the accomplishment or expectation of the merger."

        Hi-Shear stockholders considering seeking appraisal should bear in mind that the fair value of their shares of Hi-Shear common stock determined under Section 262 could be more than, the same as or less than the merger consideration they are entitled to receive pursuant to the merger agreement if

36

Table of Contents

they do not seek appraisal of their shares, and that opinions of investment banking firms as to fairness from a financial point of view are not necessarily opinions as to fair value under Section 262.

        The cost of the appraisal proceeding may be determined by the Delaware Court of Chancery and taxed upon the parties as the Delaware Court of Chancery deems equitable in the circumstances. Upon application by a Hi-Shear stockholder seeking appraisal rights, the Delaware Court of Chancery may order that all or a portion of the expenses incurred by such stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys' fees and the fees and expenses of experts, be charged pro rata against the value of all shares of Hi-Shear common stock entitled to appraisal. In the absence of such a determination, each party bears its own expenses.

        Except as explained in the last sentence of this paragraph, at any time within 60 days after the effective time of the merger, any Hi-Shear stockholder who has demanded appraisal shall have the right to withdraw such stockholder's demand for appraisal and to accept the merger consideration. After this sixty day period, the Hi-Shear stockholder may withdraw such stockholder's demand for appraisal only with the consent of the surviving corporation. If no petition for appraisal is filed with the Delaware Court of Chancery within 120 days after the effective time of the merger, Hi-Shear stockholders' rights to appraisal shall cease and all Hi-Shear stockholders shall be entitled only to receive the merger consideration. Inasmuch as the parties to the merger agreement have no obligation to file such a petition, and have no present intention to do so, any Hi-Shear stockholder who desires that such petition be filed is advised to file it on a timely basis. No petition timely filed in the Delaware Court of Chancery demanding appraisal shall be dismissed as to any Hi-Shear stockholders without the approval of the Delaware Court of Chancery, and that approval may be conditioned upon such terms as the Delaware Court of Chancery deems just.

        The foregoing is a brief summary of Section 262 that sets forth the procedures for demanding statutory appraisal rights. This summary is qualified in its entirety by reference to Section 262, a copy of the text of which is attached hereto as Annex C. Failure to comply with all the procedures set forth in Section 262 will result in the loss of a Hi-Shear stockholder's statutory appraisal rights under Delaware law.

Delisting and Deregistration of Hi-Shear Common Stock

        If the merger is completed, our common stock will no longer be traded on the NYSE Amex and will be deregistered under the Exchange Act.

Material United States Federal Income Tax Consequences of the Merger

        General.     The following discussion summarizes the material U.S. federal income tax consequences of the merger that are generally applicable to U.S. holders of our common stock upon an exchange of their shares of our common stock for cash in the merger. This summary is based upon current provisions of the Internal Revenue Code of 1986, as amended ("Code"), existing Treasury Regulations and current administrative rulings and court decisions, all of which are subject to change. Any change, which may or may not be retroactive, could materially alter the tax consequences expressed in this proxy statement. This discussion assumes that you hold our common stock as a capital asset for investment.

        This section does not discuss all of the U.S. federal income tax considerations that may be relevant to a particular stockholder in light of his or her individual circumstances or to stockholders subject to special treatment under the federal income tax laws, including, without limitation:

•

brokers or dealers in securities or foreign currencies;



•

traders;

        This summary does not address the tax consequences of the merger under state, local and foreign laws or under U.S. federal tax law other than income tax law. In addition, the following discussion does not address the tax consequences of transactions effectuated before, after, or at the same time as the merger, whether or not they are in connection with the merger, including, without limitation, the exercise or cancellation of options, warrants or similar rights to purchase stock.

an estate whose income is includible in gross income for U.S. federal income tax purposes, regardless of its source; or



•

a trust whose administration is subject to the primary supervision of a U.S. court and that has one or more U.S. persons who have the authority to control all substantial decisions of the trust.

        Consequences of the Merger to Our Stockholders.     The receipt of cash by a U.S. holder in exchange for our common stock in the merger will be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. holder will recognize capital gain or loss equal to the difference between the amount of cash received and the U.S. holder's adjusted tax basis in our common stock exchanged in the merger. Gain or loss will be calculated separately for each block of shares, with each block of shares consisting of shares acquired at the same cost in a single transaction. Such gain or loss will be long-term capital gain or loss if the U.S. holder held our common stock for more than one year as of the effective time of the merger. Certain limitations apply to the deductibility of capital losses by U.S. holders.

        Backup Withholding.     A U.S. holder may be subject to federal income tax backup withholding at the rate of 28% with respect to a payment of cash in the merger unless the U.S. holder:

•

is a corporation or comes within certain other exempt categories (including financial institutions, tax-exempt organizations and non-U.S. stockholders) and, when required, demonstrates this fact; or



•

provides a correct taxpayer identification number and certifies, under penalties of perjury, that the U.S. holder is not subject to backup withholding, and otherwise complies with applicable requirements of the backup withholding rules.

        To prevent backup withholding and possible penalties, you should complete and sign the substitute Form W-9 included in the letter of transmittal, which will be sent to you if the merger is completed. Any amount withheld under these rules may be credited against the U.S. holder's U.S. federal income tax liability, provided the required information is furnished to the IRS.

        Stockholders other than U.S. holders may be required to establish a basis for exemption from backup withholding on an appropriate Form W-8 (including a Form W-8BEN, W-8ECI, W-8EXP and W-8IMY), as applicable. If withholding is made and results in an overpayment of taxes by a non-U.S. holder, a refund may be obtained, provided that the required information is furnished to the IRS.

         We strongly urge you to consult your own tax advisor as to the specific tax consequences to you of the merger, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws, in view of your particular circumstances.

THE MERGER AGREEMENT

        The following summary of the material terms of the merger agreement is qualified in its entirety by reference to the complete text of the merger agreement, which is incorporated by reference in this proxy statement and attached to this proxy statement as Annex A. The merger agreement has been included to provide you with information regarding its terms. It is not intended to provide you with any other factual information about Hi-Shear. Such information can be found elsewhere in this proxy statement and in other public filings made by Hi-Shear with the Securities and Exchange Commission, which are available without charge at www.sec.gov or as more fully described in the section titled "Where You Can Find Additional Information." Our stockholders are urged to read the full text of the merger agreement in its entirety.

        Effective Time.     Unless the parties agree otherwise, the completion of the merger will occur as soon as practicable but in no event later than the third business day following the satisfaction or waiver of all of the closing conditions contained in the merger agreement or at such other time as the parties may agree. The merger will become effective upon the later of (i) acceptance by the Delaware Secretary of State of the parties' filing of a certificate of merger, or (ii) a subsequent time of effectiveness that the parties agree to in writing and specify in the certificate of merger.

        Effect of Merger.     Subject to the terms and conditions of the merger agreement and in accordance with Delaware law, upon the completion of the merger, Merger Sub, a wholly-owned subsidiary of Chemring and a party to the merger agreement, will merge with and into Hi-Shear. The separate corporate existence of Merger Sub will cease, and Hi-Shear will survive the merger as a wholly-owned direct or indirect subsidiary of Chemring (and is therefore sometimes referred to in this proxy statement as the "surviving corporation"). The surviving corporation will be a privately held corporation, and you will cease to have any ownership interest in the surviving corporation or any rights as a stockholder.

        Merger Consideration.     Immediately prior to the effective time of the merger, any shares of Hi-Shear common stock held by Hi-Shear itself or by Chemring or Merger Sub will be automatically canceled and cease to exist and no consideration will be paid for such shares. At the effective time of the merger, each other outstanding share of our common stock will be canceled and automatically converted into the right to receive $19.18 in cash, without interest and less any applicable withholding taxes. The per share merger consideration will be equitably adjusted in the event of any reclassification, recapitalization, stock split (including a reverse stock split) or subdivision or combination, exchange or readjustment of shares, or any stock dividend or stock distribution (excluding, in each case, normal quarterly dividends) that occurs prior to the effective time of the merger.

        Dissenting Shares.     Pursuant to the terms of the merger agreement, shares of Hi-Shear common stock outstanding immediately prior to the effective time of the merger and held by a holder who has not voted in favor of the merger agreement and the merger and who is entitled to demand and properly demands appraisal of such shares pursuant to Section 262 of the DGCL will not be converted into or be exchangeable for the right to receive the $19.18 per share merger consideration otherwise payable with respect to such shares, unless and until such holder fails to perfect or withdraws or otherwise loses his, her or its right to appraisal and payment under the DGCL. If, after the effective time of the merger, any such holder fails to perfect or withdraws or loses his, her or its right to appraisal, such holder's shares will be treated as if they had been converted as of the effective time of the merger into the right to receive $19.18 per share in cash, without interest and less applicable withholding taxes. Hi-Shear has agreed to give Chemring prompt notice of any demands received by us for appraisal of shares of Hi-Shear common stock pursuant to the DGCL and the opportunity to participate in all negotiations and proceedings with respect to such demands. Hi-Shear has also agreed that prior to the effective time of the merger, we will not, except with the prior written consent of Chemring, make any payment with respect to, or settle or offer to settle, any such demands.

Table of Contents

        Treatment of Stock Options and Restricted Stock Units.     As of the record date, 28,719 options to purchase the common stock of Hi-Shear were issued and outstanding. At the effective time of the merger, each outstanding option to purchase our common stock (whether vested or unvested) will be deemed fully vested and be cancelled, and each holder of such option will be entitled to receive in exchange for such option an amount in cash equal to the product of (i) the number of shares for which such option is exercisable and (ii) the excess of the per share price of $19.18 to be paid with respect to our common stock in the merger over the exercise price of such option for each share represented by such option, without interest and less any applicable tax withholdings.

        As of the record date, 8,860 unvested restricted stock units of Hi-Shear were outstanding that are settleable in shares of our common stock. Under the terms of the merger agreement, as of the effective time, each outstanding restricted stock unit (whether vested or unvested) will be cancelled and be converted into the right to receive the per share price of $19.18 to be paid with respect to our common stock in the merger, without interest and less any applicable tax withholdings.

        Exchange of Stock Certificates.     Prior to the effective time of the merger, Chemring will enter in an agreement with a bank or trust company reasonably acceptable to us to act as paying agent to receive the merger consideration. As promptly as practicable following the effective time of the merger and in any event no later than the first business day thereafter, Chemring will deposit, or cause to be deposited, with the paying agent cash amounts sufficient to enable the paying agent to pay the aggregate merger consideration to the holders of shares of our common stock.

        The merger agreement provides that promptly after the completion of the merger, but in no event later than three business days thereafter, Chemring and the surviving corporation will cause the paying agent to mail to each record holder of (i) certificates ("Certificates") representing outstanding shares of our common stock or (ii) uncertified shares of our common stock represented by book entry ("Book Entry Shares") which, in each case, were converted into the right to receive a portion of the merger consideration, a letter of transmittal and instructions for use in surrendering Certificates and/or Book Entry Shares in exchange for the merger consideration. No stockholder should surrender any of his, her or its Certificates until the stockholder receives the letter of transmittal and other materials for such surrender. Upon surrender of a Certificate or Book Entry Share to the paying agent, together with a letter of transmittal, duly completed and executed in accordance with the instructions, the holder of such Certificate or Book Entry Share will be entitled to receive the per share merger consideration for each share formerly represented by such Certificate or Book Entry Share, without any interest and less any applicable withholding tax. Each of the paying agent, the surviving corporation, and Chemring will be entitled to deduct and withhold from the merger consideration such amounts as may be required to be deducted or withheld under applicable tax laws.

        After the effective time of the merger, there will be no further transfers of our common stock. In the event that merger consideration is to be delivered in the name of a person other than the person in whose name any Certificate is registered, it will be a condition of payment that the Certificate so surrendered will be properly endorsed or otherwise in proper form for transfer, that the signatures on such Certificate or any related stock power will be properly guaranteed and that the person requesting payment will pay any related transfer or other taxes, or that such person establish to the satisfaction of the surviving corporation that such taxes have been paid or are not applicable.

        If your Certificate has been lost, stolen or destroyed, the paying agent will deliver to you the applicable merger consideration for the shares represented by that Certificate if:

•

you make an affidavit (in a form and substance reasonably acceptable to Chemring) claiming such Certificate has been lost, stolen or destroyed; and

41

---

Table of Contents

•

if required by Chemring, you post a bond in such amount as Chemring or the paying agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the surviving corporation with respect to such Certificate.

         You should not send any of your Certificates now and should send them only pursuant to instructions set forth in the letters of transmittal to be mailed to our stockholders promptly after the completion of the merger. In all cases, the merger consideration will be paid only in accordance with the procedures set forth in the merger agreement and such letters of transmittal.

        The merger agreement provides that one year after the completion of the merger, the paying agent will deliver to the surviving corporation upon its demand any funds made available to the paying agent which have not been claimed by the former holders of our common stock, and that any holders of Certificates or Book Entry Shares who have not complied with the above-described procedures to receive payment of the merger consideration during such one year period may thereafter look only to Chemring and the surviving corporation, as general unsecured creditors thereof with respect to the portion of the merger consideration payable upon due surrender of their Certificates or Book Entry Shares.

        Representations and Warranties.     The merger agreement contains representations and warranties of Hi-Shear and Chemring customary for agreements of this nature with regard to their respective businesses, financial condition and other facts pertinent to the merger.

        Definition of Material Adverse Effect.     Several of the representations and warranties made by us and Chemring in the merger agreement and certain conditions to Chemring's performance of its obligations under the merger agreement are qualified by reference to whether the item in question would have a "material adverse effect" on us or Chemring, as the case may be.

        The merger agreement provides that a "material adverse effect," with respect to Hi-Shear, means any event, change, circumstance, effect or state of facts that is, or would reasonably be expected to be, materially adverse to, or has had or would reasonably be expected to have a material adverse effect on (i) our business, condition (financial or otherwise) or results of operations or (ii) our ability to timely perform, in all material respects, our obligations under the merger agreement or to consummate the transactions contemplated thereby. However, except to the extent otherwise set forth below, "material adverse effect" does not include the effect of any circumstance, change, development, event or state of facts arising out of or attributable to any of the following:

        (a)   the industry and markets in which Hi-Shear operates generally;

        (b)   general economic or political conditions (including those affecting the securities markets);

        (c)   the public announcement or pendency of the merger agreement or the consummation of the transaction contemplated thereby (including any loss of customers or employees or any labor disputes or employee strikes, slowdowns, job actions or work stoppages or labor union activities);

        (d)   our the failure to meet projections of earnings, revenues or other financial measures (whether such projections were made by us or independent third parties), in and of itself;

        (e)   any change in our stock price or trading volume, in and of itself;

        (f)    any litigation arising from the negotiation, execution, announcement or pendency of merger agreement or the consummation of the transactions contemplated thereby (including litigation against us or any of our officers or directors alleging breach of their fiduciary duties);

        (g)   acts of war (whether or not declared), sabotage or terrorism, military actions or the escalation thereof or other force majeure events (such as natural disasters, acts of God or other

45

Table of Contents

events not within our reasonable control) occurring after the date of execution of the merger agreement;

        (h)   any changes in applicable laws, regulations or accounting rules; or

        (i)    the taking of any action required by the merger agreement or specifically consented to in writing by Chemring or Merger Sub.

        In the cases of paragraphs (a), (b), (g) and (h) above, to the extent such circumstance, change, development, event or state of facts has had a materially disproportionate effect on Hi-Shear in comparison to other companies in the same industry as Hi-Shear, such circumstance, change, development, event or state of facts will be considered in the determination of the occurrence of a "material adverse effect."

        Acquisition Proposals by Third Parties.     We have agreed that we will not authorize or permit any of our officers, directors, employees, agents and representatives, including any investment banker, attorney or accountant retained by us to, directly or indirectly:

•

initiate, solicit, or knowingly encourage or facilitate any inquiries, proposals or offers with respect to any acquisition proposal (as defined in the merger agreement and described below in the section captioned "The Merger Agreement—Definitions of Acquisition Proposal and Superior Proposal");



•

engage or participate in any negotiations concerning, or furnish any nonpublic information relating to us to any third party in connection with, any acquisition proposal;



•

approve, endorse or recommend any acquisition proposal; or



•

approve, endorse or recommend, or execute or enter into any letter of intent, agreement in principle, merger agreement, acquisition agreement or other similar agreement relating to any acquisition proposal.

        We have also agreed that we will immediately cease and terminate any existing activities, discussions or negotiations with any persons that were conducted by us prior to the date of the merger agreement with respect to any acquisition proposal.

        Even though we have agreed to the provisions described above relating to the non-solicitation of acquisition proposals, our board of directors may:

•

take and disclose to our stockholders a position with respect to a tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act; or



•

make any disclosure to our stockholders, if, based on advice from outside counsel, our board of directors determines in good faith that failing to do so would be reasonably likely to violate its fiduciary duty under applicable laws.

        Furthermore, notwithstanding the foregoing restrictions with respect to acquisition proposals by third parties, at any time prior to obtaining stockholder approval and adoption of the merger agreement and the merger, we or our board of directors, directly or indirectly through advisors, agents or other intermediaries, may furnish information concerning our businesses, properties or assets to any person or group including furnishing nonpublic information pursuant to an appropriate confidentiality agreement, and may engage in discussions and negotiations with such person or group concerning an acquisition proposal if, and only if:

•

such person or group has, after the date of execution of the merger agreement, submitted an unsolicited acquisition proposal which our board of directors determines in good faith is reasonably likely to result in a superior proposal (as defined in the merger agreement and

46

---

Table of Contents

described below in the section captioned "The Merger Agreement—Definitions of Acquisition Proposal and Superior Proposal"); or

•

our board of directors determines in good faith, based upon advice of outside counsel, that failing to do so would be reasonably likely to violate its fiduciary duties to our stockholders under applicable laws.

        We have agreed that we will immediately advise Chemring of any proposal or inquiry received by us with respect to any acquisition proposal.

        Additionally, we have agreed with Chemring that neither the special committee nor our board of directors may (i) withdraw or modify, or qualify in a manner adverse to Chemring the recommendation of the special committee and our board of directors of the merger agreement or the transactions contemplated thereby, or (ii) approve or recommend, or permit Hi-Shear to enter into, any letter of intent, memorandum of understanding, acquisition agreement or similar agreement constituting or relating to any acquisition proposal unless:

•

we have received an acquisition proposal that our board of directors determined in good faith, based on advice of outside counsel, constitutes a superior proposal; or



•

our board of directors has determined in good faith, based upon advice of outside counsel, that failing to take such action would be reasonably likely to constitute a breach of its fiduciary duties to our stockholders under applicable laws.

        However, no such action may be taken by us in response to a superior proposal until after the fourth business day following Chemring's receipt of written notice from us advising Chemring that our board of directors intends to take such action and specifying the terms and conditions of such superior proposal. Furthermore, in determining whether to take such action in response to a superior proposal, our board of directors must take into account any changes to the terms of the merger agreement proposed by Chemring in response to our intention to take such action or otherwise, in determining whether such third party acquisition proposal still constitutes a superior proposal.

        Definitions of Acquisition Proposal and Superior Proposal.     For purposes of the merger agreement (and this summary), "acquisition proposal" means, any inquiry, proposal or offer from any person or group of persons for (A) a merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving an acquisition of Hi-Shear or (B) the acquisition in any manner, directly or indirectly, of 15% or more of the equity securities or consolidated total assets of Hi-Shear (excluding inventory sold or proposed to be sold in the ordinary course of business consistent with past practice), in each case other than the merger.

        For purposes of the merger agreement (and this summary), "superior proposal" mean any acquisition proposal (provided that for purposes of this definition references to "15% or more" in the definition of "acquisition proposal" shall be deemed to be references to "greater than 50%") (A) on terms which the our board of directors determines in good faith, based upon advice of outside counsel, to be more favorable from a financial point of view to our stockholders, taking into account all the terms and conditions of such proposal, and the merger agreement, (B) that, in the good faith reasonable judgment of our board, based upon advice of outside counsel, is reasonably capable of being completed, taking into account all financial, regulatory, legal and other aspects of such proposal, and (C) is not subject to any due diligence conditions.

ADJOURNMENT OF THE SPECIAL MEETING
(Proposal 2)

        We are submitting a proposal for consideration at the special meeting to authorize the named proxies to approve any adjournments of the special meeting if there are not sufficient votes to approve and adopt the merger agreement and the merger at the time of the special meeting or any adjournment or postponement of that meeting. Even though a quorum may be present at the special meeting or any such adjournment or postponement, it is possible that we may not have received sufficient votes to approve and adopt the merger agreement and the merger by the time of the special meeting or such adjournment or postponement. In that event, we would need to adjourn the special meeting in order to solicit additional proxies. The adjournment proposal relates only to an adjournment of the special meeting for purposes of soliciting additional proxies to obtain the requisite stockholder approval to adopt the merger agreement and the merger. Any other adjournment of the special meeting (e.g., an adjournment required because of the absence of a quorum) would be voted upon pursuant to the discretionary authority granted by the proxy.

        The proposal to approve one or more adjournments of the special meeting requires the affirmative vote of holders of a majority of the shares of our common stock present or represented at the special meeting and entitled to vote on the proposal.

        To allow the proxies that have been received by us at the time of the special meeting to be voted for an adjournment, if determined to be necessary by Hi-Shear, we are submitting a proposal to approve one or more adjournments, and only under those circumstances, to you for consideration. Our board unanimously recommends that you vote "FOR" the adjournment proposal so that proxies may be used for that purpose, should it become necessary. Properly executed proxies will be voted "FOR" the adjournment proposal, unless otherwise indicated on the proxies. If the special meeting is adjourned for 30 days or less, we are not required to give notice of the time and place of the adjourned meeting unless our board fixes a new record date for the special meeting.

        The adjournment proposal relates only to an adjournment of the special meeting occurring for purposes of soliciting additional proxies for approval and adoption of the merger agreement and the merger in the event that there are insufficient votes to approve and adopt the merger agreement and the merger. Our board retains full authority to the extent set forth in our bylaws and Delaware law to adjourn the special meeting for any other purpose, or to postpone the special meeting before it is convened, without the consent of any of our stockholders.

        (b)   At the Effective Time, each restricted stock unit or similar right (each, a " Company RSU ") to purchase Shares granted under any Company Equity Plan, whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be canceled and, in exchange therefor, Parent shall pay or cause the Surviving Corporation to pay to each former holder of each such canceled Company RSU as soon as practicable following the Effective Time, an amount in cash, without interest, equal to the Per Share Merger Consideration per Share underlying such Company RSU.

        (c)   Prior to the Effective Time, the Company shall use its commercially reasonable efforts to obtain all consents and make all amendments, if any, to the terms of the Company Equity Plans and each outstanding Company Stock Option and Company RSU award agreement, and shall take all other actions within its control that are necessary to give effect to the provisions of this Section 3.2 .

connection with the exchange of Shares for the Merger Consideration and other amounts contemplated by Section 3.1 and Section 3.2 .

        (b)   As promptly as practicable following the Effective Time and in any event not later than the third Business Day thereafter, Parent and the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of (i) an outstanding certificate or outstanding certificates (" Certificates ") that immediately prior to the Effective Time represented outstanding Shares or (ii) uncertificated Shares represented by book-entry (" Book-Entry Shares ") which, in each case, were converted into the right to receive the Per Share Merger Consideration with respect thereto pursuant to Section 3.1(a) , (A) a form of letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares held by such Person shall pass, only upon proper delivery of the Certificates to the Paying Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the letter of transmittal) and (B) instructions for use in effecting the surrender of Certificates or Book-Entry Shares in exchange for the Merger Consideration payable with respect thereto pursuant to Section 3.1(a) . Upon surrender of a Certificate or Book-Entry Share to the Paying Agent, together with such letter of transmittal, duly completed and validly executed, and such other documents as the Paying Agent may reasonably require, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the Per Share Merger Consideration for each Share formerly represented by such Certificate or Book-Entry Share, and such Certificate or Book-Entry Share shall forthwith be canceled. No interest shall be paid or shall accrue on any cash payable upon surrender of any Certificate or Book-Entry Share. In the event that the Merger Consideration is to be paid to a Person other than the Person in whose name any Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer, that the signatures on such Certificate or any related stock power shall be properly guaranteed and that the Person requesting such payment shall pay any transfer or other Taxes required by reason of such payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such Taxes have been paid or are not applicable. Until surrendered as contemplated by this Section 3.3 , each share represented by a Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender or transfer the Per Share Merger Consideration payable in respect of each Share theretofore represented by such Certificate or Book-Entry Share, as applicable, pursuant to Section 3.1(a) , without any interest thereon.

        (c)   All cash paid upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates or Book-Entry Shares. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for transfer or transfer is sought for Book-Entry Shares, such Certificates or Book-Entry Shares shall be canceled and exchanged as provided in this Article III , subject to applicable Law in the case of Dissenting Shares.

        (d)   The Paying Agent shall invest any cash included in the Payment Fund as directed by Parent in investments that are customary for transactions of similar nature and size as the Merger. If for any reason (including investment losses) the cash in the Payment Fund is insufficient to fully satisfy all of the payment obligations to be made in cash by the Paying Agent hereunder (but subject to Section 3.4 ), Parent shall promptly deposit (or cause to be deposited) cash into the Payment Fund in an amount which is equal to the deficiency in the amount of cash required to

fully satisfy such cash payment obligations. Any interest and other income resulting from such investments shall be payable to the Surviving Corporation.

        (e)   At any time following the date that is twelve (12) months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) which have been made available to the Paying Agent and which have not been disbursed to holders of Certificates or Book-Entry Shares, and thereafter such holders shall be entitled to look to Parent and the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the portion of the Merger Consideration payable upon due surrender of their Certificate or Book-Entry Shares.

        (f)    If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit, in form and substance reasonably acceptable to Parent, of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Paying Agent, the posting by such Person of a bond in such amount as Parent or the Paying Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect thereof pursuant to this Agreement.

        Section 3.4     Withholding Rights.     Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Shares, Company Stock Options and Company RSUs or otherwise pursuant to this Agreement, such amounts as Parent, the Surviving Corporation or the Paying Agent is or are required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

        Section 3.5     Dissenting Shares.     Notwithstanding anything in this Agreement to the contrary, Shares issued and outstanding immediately prior to the Effective Time that are held by any holder who has not voted in favor of the Merger and who is entitled to demand and properly demands appraisal of such Shares pursuant to Section 262 of the DGCL (" Dissenting Shares ") shall not be converted into the right to receive the Merger Consideration, unless and until such holder shall have failed to perfect, or shall have effectively withdrawn or lost, such holder's right to appraisal under the DGCL. Dissenting Shares shall be treated in accordance with Section 262 of the DGCL. If any such holder fails to perfect or withdraws or loses any such right to appraisal, each such Share of such holder shall thereupon be converted into and become exchangeable only for the right to receive, as of the later of the Effective Time and the time that such right to appraisal has been irrevocably lost, withdrawn or expired, the Merger Consideration in accordance with Section 3.1(a) . The Company shall serve prompt notice to Parent of any demands for appraisal of any Shares, attempted withdrawals of such notices or demands and any other instruments received by the Company relating to rights to appraisal, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands.

        Section 6.12     Indemnification, Exculpation and Insurance.     

        (a)   Without limiting any additional rights that any Indemnified Party may have under any agreement or Company Plan, for a period of six (6) years from the Effective Time, Parent shall cause the Surviving Corporation to indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time, a director or officer of the Company or any of its Subsidiaries (the " Indemnified Parties "), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys' fees and disbursements (collectively, " Costs "), arising out of or relating to any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, based as a whole or in part on or arising out of or relating as a whole or in part to the fact that the Indemnified Party is or was an officer, director, employee, fiduciary or agent of the Company or any of its Subsidiaries or a trustee (or the like) of any Company Plan, whether pertaining to any matters existing or occurring at or prior to the Effective Time and whether asserted or claimed prior to, at or after the Effective Time (the " Indemnified Liabilities "), including all Indemnified Liabilities based as a whole or in part on, or arising as a whole or in part out of, or relating to this Agreement, to the fullest extent permitted under applicable Law.

the defense of any such claim, action, suit, proceeding or investigation from Parent or the Surviving Corporation to the fullest extent permitted under applicable Law in effect on the date hereof within ten (10) Business Days of receipt by Parent or the Surviving Corporation from the Indemnified Party of a request therefore, provided, that any Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification.

        (b)   Except as may be required by applicable Law, Parent, Merger Sub and the Company agree that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Indemnified Party as provided in the certificate of incorporation or bylaws (or comparable organizational documents) of the Company or in any indemnification agreement between such Indemnified Party and the Company shall survive the Merger and continue in full force and effect, and shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party.

        (c)   Prior to the Effective Time, the Company shall purchase a six-year prepaid "tail policy" on terms and conditions (in both amount and scope) providing substantially equivalent benefits as the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by the Company with respect to matters arising on or before the Effective Time, covering without limitation the transactions contemplated hereby. Such policy, including the amount to be paid therefor, shall be subject to approval by Parent, which approval shall not be unreasonably withheld, conditioned or delayed. If such prepaid tail policy has been obtained by the Company prior to the Effective Time, Parent shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations of the Company thereunder to be honored by the Surviving Corporation.

        (d)   Notwithstanding anything herein to the contrary, if any Action (whether arising prior to, at or after the Effective Time) is instituted against any Indemnified Party on or prior to the sixth anniversary of the Effective Time, the provisions of this Section 6.12 shall continue in effect until the final disposition of such Action.

        (e)   The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise. The provisions of this Section 6.12 shall survive the consummation of the Merger and, notwithstanding any other provision of this Agreement, expressly are intended to benefit, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives.

        (f)    In the event that the Surviving Corporation or Parent or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation or Parent, as the case may be, shall succeed to the obligations set forth in this Section 6.12 .

        Section 6.13     Rule 16b-3.     Prior to the Effective Time, the Company shall take such steps as may be reasonably necessary or advisable hereto to cause dispositions of Company equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

        Section 6.14     Public Announcements.     The initial press releases issued by each party announcing this Agreement will be in a form that is mutually acceptable to Parent and the Company. Thereafter, each of Parent and Merger Sub, on the one hand, and the Company, on the other hand, shall, to the

A-34

extent reasonably practicable, consult with each other before issuing, and give each other a reasonable opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the Merger and the other transactions contemplated hereby and shall not issue any such press release or make any public announcement prior to such consultation and review, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system.

        Section 6.15     Non-Solicitation of Employees.     If this Agreement is terminated prior to the Effective Time, Parent will not and will cause its Affiliates not to, for a period of three (3) years thereafter, without the prior written consent of the Company, solicit (other than a solicitation by general advertisement) any person who is an employee of the Company, at the date hereof or at any time hereafter that precedes such termination, to terminate his or her employment with the Company. Parent agrees that any remedy at law for any breach by Parent (whether in connection with its own actions or those of its Affiliates) of this Section 6.15 would be inadequate, and that the Company would be entitled to injunctive relief in such a case. If it is ever held that this restriction on Parent is too onerous and is not necessary for the protection of the Company, Parent agrees that any court of competent jurisdiction may impose such lesser restrictions which such court may consider to be necessary or appropriate to properly protect the Company.

        Section 6.16     Obligations of Parent and Merger Sub.     Parent shall take all action necessary to cause Merger Sub to perform its obligations under this Agreement and to consummate the Merger on and subject to the terms and conditions set forth in this Agreement.

        Section 6.17     Stockholder Litigation.     The Company shall give Parent the opportunity to participate (at Parent's expense) in the defense or settlement of any stockholder Action against the Company and its directors relating to the Merger or the other transactions contemplated by this Agreement; provided, however, that no such settlement shall be agreed to without Parent's prior written consent, which consent shall not be unreasonably withheld or delayed, except that Parent shall not be obligated to consent to any settlement which does not include full release of Parent and its Affiliates or which imposes an injunction or other equitable relief upon Parent or any of its Affiliates (including, after the Effective Time, the Surviving Corporation).

        Section 6.18     Closing Cash and Related Matters.     The Company agrees that (a) it shall use commercially reasonable efforts to cause its cash and cash equivalents at and after November 30, 2009 to be not less than $2,950,000 (reduced by the payment after the date hereof of any expenses of the transactions contemplated hereby), and (b) except as otherwise agreed by Parent in its sole discretion, at and as of the Closing the Company shall have no indebtedness for borrowed money and its assets shall not be subject to any Liens relating to indebtedness for borrowed money.

        Section 6.19     Title Policies.     The Company shall obtain policies of title insurance in an amount not less than $5,000,000 insuring the Company's fee simple title to the Owned Real Property, subject only to standard exceptions expressly not to include any Liens other than Permitted Liens.

        (d)   Notwithstanding anything to the contrary in this Agreement, the Company acknowledges and agrees on behalf of itself and its Affiliates that the Termination Fee is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent and Merger Sub in the circumstances in which the Termination Fee is payable for the efforts and resources expended and opportunity forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. The Company acknowledges and hereby agrees that the provisions of this Section 8.3 are an integral part of the transactions contemplated by this Agreement, and that, without such provisions, Parent would not have entered into this Agreement.

        Section 8.4     Frustration of Conditions.     The right to terminate this Agreement pursuant to Section 8.1(c)(ii) or 8.1(d)(ii) shall not be available if the failure of the party so requesting termination for failure to fulfill any obligation under this Agreement shall have been the cause of the failure of such condition to be satisfied on or prior to such date.

Dear Members of the Special Committee and the Board of Directors:

        We understand that Hi-Shear Technology Corporation, a Delaware corporation ("Company"), and Chemring Group PLC, a company organized under the laws of England and Wales ("Buyer"), and Parkway Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Buyer ("Merger Sub"), propose to enter into an Agreement and Plan of Merger, dated as of September 16, 2009 (the "Agreement"), pursuant to which Buyer will acquire Company (the "Transaction"). Pursuant to the Transaction, Merger Sub will be merged with and into Company and each outstanding share of the common stock, par value $0.001 per share of the Company ("Company Common Stock") (other than shares held by (i) the Company, the Buyer, Merger Sub, or any wholly owned subsidiary of the Company and (ii) those persons who demand an appraisal of their shares (collectively, "Excluded Holders")) will be converted into the right to receive $19.18 in cash (the "Consideration"). The terms and conditions of the Transaction are more fully set forth in the Agreement.

        You have requested our opinion as of the date hereof as to the fairness, from a financial point of view, to holders of Company Common Stock (other than Excluded Holders) of the Consideration to be paid to such holders in the Transaction.

        In connection with this opinion, we have:

        We have assumed and relied upon the accuracy and completeness of the foregoing information, without independent verification of such information. We have not conducted any independent valuation or appraisal of any of the assets or liabilities (contingent or otherwise) of Company or concerning the solvency or fair value of Company, and we have not been furnished with such valuation or appraisal. With respect to the financial forecasts that we have reviewed, we have assumed, with the consent of Company, that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Company as to the future financial

The issuance of this opinion was approved by the Opinion Committee of Lazard Frères & Co. LLC.

Annex C

SECTION 262 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

§ 262. Appraisal Rights.

        (a)   Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

        (b)   Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

        (1)   Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

        (2)   Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

        a.     Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

        b.     Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

        c.     Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

        d.     Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

        (3)   In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

Table of Contents

        (c)   Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

        (d)   Appraisal rights shall be perfected as follows:

        (1)   If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

        (2)   If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be

C-2

Table of Contents

not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

        (e)   Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person's own name, file a petition or request from the corporation the statement described in this subsection.

        (f)    Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

        (g)   At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

        (h)   After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all

relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

        (i)    The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

        (j)    The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

        (k)   From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

        (l)    The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
