MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

To our Shareholders:

On December 11, 2018, Sparton Corporation (which we refer to as the “Company”), Striker Parent 2018, LLC (which we refer to as “Parent”), and Striker Merger Sub 2018, Inc., a wholly owned subsidiary of Parent (which we refer to as “Merger Sub”), entered into an Agreement and Plan of Merger (which we refer to as the “merger agreement”) that provides for Parent to acquire the Company. Upon the terms and subject to the conditions set forth in the merger agreement, Merger Sub will merge with and into the Company (which we refer to as the “merger”), so that the Company will be the surviving corporation in the merger and a wholly owned subsidiary of Parent. Parent and Merger Sub are owned by funds and accounts affiliated with Cerberus Capital Management, L.P., a private investment firm.

At the effective time of the merger (which we refer to as the “effective time”), each share of the Company’s common stock, par value $1.25 per share (which we refer to as “Company common stock”), issued and outstanding immediately prior to the effective time of the merger (except for shares of Company common stock held by (i) Parent, Merger Sub or any other wholly owned subsidiary of Parent or the Company or any wholly owned subsidiary of the Company and (ii) holders of Company common stock (which we refer to as “Company shareholders”) who have properly exercised dissenters’ rights) will be converted into the right to receive $18.50 in cash without interest (which we refer to as the “merger consideration”). The merger consideration represents a premium of:

On January 18, 2019, the most recent practicable date before the accompanying proxy statement was mailed to the Company shareholders, the closing price for Company common stock on the NYSE was $18.38 per share. We urge you to obtain current market quotations for Sparton Corporation (trading symbol “SPA”).

The Company will hold a special meeting of the Company shareholders (which we refer to as the “special meeting”) in connection with the merger. Company shareholders will be asked to vote to adopt the merger agreement and approve related matters, as described in the accompanying proxy statement. Adoption of the merger agreement requires the affirmative vote in person or by proxy of holders of at least two-thirds of the outstanding shares of Company common stock entitled to vote thereon.

The special meeting will be held on March 1, 2019, at 10:00 a.m., central time, at the offices of the Company, located at 425 North Martingale Road, Suite 1000, Schaumburg, Illinois 60173.

The board of directors of the Company has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to the Company shareholders and are in the best interests of the Company and the Company shareholders, declared advisable and approved the merger agreement and the execution, delivery and performance of the merger agreement and the transactions contemplated by the merger agreement, including the merger, and directed that a proposal for the adoption of the merger agreement be submitted to the Company shareholders for consideration at the special meeting. The board of directors of the Company recommends that the Company shareholders vote “FOR” the adoption of the merger agreement and “FOR” the other matters to be considered at the special meeting.

The accompanying proxy statement provides detailed information about the special meeting, the merger, the merger agreement, the documents related to the merger and other related matters. Please carefully read the entire proxy statement, including its annexes, and any documents incorporated in the proxy statement by reference. In particular, you should read the section entitled “Cautionary Statement Concerning Forward-Looking Statements” in this proxy statement for a description of the risks related to the proposed merger and the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the fiscal year ended July 1, 2018, and the other reports filed by the Company with the Securities and Exchange Commission and incorporated by reference into the proxy statement, for a description of the risks related to the Company’s business.

On behalf of the board of directors of the Company, thank you for your cooperation and continued support of the Company.

Sincerely,

/s/ Joseph J. Hartnett

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

To be held on March 1, 2019

NOTICE IS HEREBY GIVEN that Sparton Corporation, an Ohio corporation (which we refer to as the “Company”), will hold a special meeting of holders of shares of common stock of the Company (which we refer to as “Company common stock” and holders of which we refer to as “Company shareholders”) on March 1, 2019, at 10:00 a.m., central time, at 425 North Martingale Road, Suite 1000, Schaumburg, Illinois 60173 (which we refer to as the “special meeting”) to consider and vote upon the following matters:

The board of directors of the Company has fixed the close of business on January 18, 2019 as the record date for the special meeting. Only Company shareholders of record at that time are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement thereof. Adoption of the merger agreement requires the affirmative vote in person or by proxy of holders of at least two-thirds of the outstanding shares of Company common stock entitled to vote thereon. Approval of the compensation proposal and the adjournment proposal requires the affirmative vote of the holders of a majority of the shares of Company common stock present in person or represented by proxy at the special meeting.

The board of directors of the Company has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to the Company shareholders and are in the best interests of the Company and the Company shareholders, has declared advisable and approved the merger agreement and the execution, delivery and performance of the merger agreement and the transactions contemplated by the merger agreement, including the merger, has directed that a proposal for the adoption of the merger agreement be submitted to the Company shareholders for consideration at the special meeting, and unanimously recommends that the Company shareholders vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal.

Your vote is very important. We cannot complete the merger unless the Company shareholders approve the merger proposal.

If you have any questions about the merger or the accompanying proxy statement, would like additional copies of the proxy statement or need assistance voting your shares of Company common stock, please contact the Company’s proxy solicitor, Morrow Sodali LLC, 470 West Avenue, 3rd floor, Stamford, CT 06902, by telephone at (203) 658-9400 (for banks and brokerage firms) or (800) 662-5200 (for shareholders) or by email at spa.info@morrowsodali.com.

If you hold shares of Company common stock in your name as a shareholder of record and are voting by mail, please complete, sign, date and return the accompanying proxy card in the enclosed postage-paid return envelope. This will not prevent you from voting in person, but it will help to secure a quorum and avoid added solicitation costs. Any holder of record of shares of Company common stock who is present at the special meeting may vote in person instead of by proxy, thereby canceling any previous proxy. In any event, a proxy may be revoked at any time before the special meeting in the manner described in the accompanying proxy statement. Information and applicable deadlines for voting through the Internet or by telephone are set forth in the enclosed proxy card instructions. If you hold your stock in “street name” through a bank, broker or other holder of record, please follow the instructions on the voting instruction card furnished by the record holder.

Under Ohio law, Company shareholders who do not vote in favor of or consent to the adoption of the merger agreement will have dissenters’ rights to seek the fair cash value of their shares of Company common stock, but only if they submit a written demand to the Company for such fair cash value before the vote on the merger proposal and comply with the other Ohio law procedures explained in the accompanying proxy statement. Company shareholders who do not vote in favor of the merger proposal and who submit a written demand for payment of the fair cash value of their shares of Company common stock before the vote on the merger proposal and comply with the other Ohio law procedures will not receive the merger consideration.

The accompanying proxy statement provides a detailed description of the special meeting, the merger, the merger agreement, the documents related to the merger and other related matters. Please carefully read the entire proxy statement, including its annexes and any documents incorporated in the proxy statement by reference.

This proxy statement contains important information about the merger and the other proposals being voted on at the special meeting. You should read it carefully and in its entirety.

THE SPECIAL MEETING

This section contains information for the Company shareholders about the special meeting that the Company has called to allow the Company shareholders to consider and vote on the merger proposal and other matters. The Company is mailing this proxy statement to you, as a Company shareholder, on or about January 25, 2019. This proxy statement is accompanied by a notice of the special meeting and a form of proxy card that the Company board is soliciting for the Company at the special meeting and at any adjournments or postponements thereof.

Date, Time and Place of the Special Meeting

This proxy statement is being furnished to our shareholders as part of the solicitation of proxies by the Company board from the Company shareholders for use at the special meeting to be held on March 1, 2019, at 10:00 a.m., central time, at the offices of the Company, located at 425 North Martingale Road, Suite 1000, Schaumburg, Illinois 60173, or at any postponement or adjournment thereof.

Purpose of the Special Meeting

At the special meeting, you will be asked to consider and vote upon the following matters:

The Company shareholders must adopt the merger agreement by approving the merger proposal in order to consummate the merger. A copy of the merger agreement is attached as Annex A to this proxy statement. You are urged to read the merger agreement carefully in its entirety.

Recommendation of the Company Board of Directors

The Company board has unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to the Company shareholders and in the best interests of the Company and the Company shareholders and declared advisable and approved the merger agreement and the execution, delivery and performance of the merger agreement and the transactions contemplated by the merger agreement, including the merger. The Company board unanimously recommends that the Company shareholders vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal. See “The Merger—Recommendation of the Company Board of Directors; Reasons for the Merger” for a more detailed discussion of the Company board’s recommendation.

Record Date and Quorum

The Company board has fixed the close of business on January 18, 2019 as the record date for the determination of the Company shareholders entitled to notice of, and to vote at, the special meeting. As of the close of business on the record date, there were 9,834,723 shares of Company common stock outstanding and entitled to vote, held by approximately 263 holders of record. You will have one vote on each matter properly coming before the special meeting for each share of Company common stock that you owned on the record date.

The presence in person or by proxy of the holders of record of a majority of the outstanding voting shares of the Company as of the record date is necessary to constitute a quorum at the special meeting. All shares of Company common stock present in person or represented by proxy, including abstentions, will be treated as present for purposes of determining the presence or absence of a quorum for all matters voted on at the special meeting. Because, under applicable rules, brokers holding shares in “street name” do not have discretionary voting

21

authority with respect to any of the three proposals described in this proxy statement, if a beneficial owner of Company common stock held in “street name” does not give voting instructions to the broker that is the record holder of its, his or her shares, then those shares will not be counted as present in person or by proxy at the special meeting if no other proposals are brought before the special meeting.

Vote Required

Merger Proposal

Compensation Proposal

Adjournment Proposal

Voting, Proxies and Revocation

Attending the Special Meeting

All Company shareholders, including shareholders of record and shareholders who hold their shares through banks, brokers or other holders of record or through the 401(k) Plan, are invited to attend the special meeting. Shareholders of record can vote in person at the special meeting. If you are not a shareholder of record, you must obtain a legal proxy executed in your favor from the record holder of your shares to be able to vote in person at the special meeting. If you hold your shares in the 401(k) Plan, you may not vote in person at the special meeting. If you plan to attend the special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership. In addition, you must bring a form of personal photo identification with you in order to be admitted to the meeting. The Company reserves the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification.

22

Voting by Shareholders of Record

If you are a shareholder of record, you may vote your shares of Company common stock on matters presented at the special meeting in any of the following ways:

Voting of Shares Held in “Street Name”; Broker Non-Votes

If you are a beneficial owner of shares of Company common stock held in “street name,” you should receive instructions from your bank, broker or other holder of record that you must follow in order to have your shares of Company common stock voted. If you have not received such voting instructions or require further information regarding such voting instructions, contact your bank, broker or other holder of record. If your bank, broker or other holder of record holds your shares of Company common stock in “street name,” such record holder will vote your shares of Company common stock only if you provide instructions on how to vote by filling out the voter instruction form sent to you by such record holder with this proxy statement. Please note that, if you are a beneficial owner of shares of Company common stock held in “street name” and wish to vote in person at the special meeting, you must obtain a legal proxy executed in your favor from your bank, broker or other holder of record and present such legal proxy at the special meeting.

Under stock exchange rules, brokers who hold shares of Company common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, such record holders are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine.” “Broker non-votes” are shares held in “street name” by brokers that are present in person or represented by proxy at the special meeting, but for which the beneficial owner has not provided the record holder with instructions on how to vote on a particular proposal and such record holder does not have discretionary voting power with respect to such proposal. Under applicable rules, brokers holding shares in “street name” do not have discretionary voting authority with respect to any of the three proposals described in this proxy statement. If a beneficial owner of Company common stock held in “street name” does not give voting instructions to the applicable broker, then those shares will not be counted as present in person or by proxy at the special meeting. As the vote to approve the merger proposal is based on the total number of shares of Company common stock outstanding at the close of business on the record date, if you fail to issue voting instructions to your broker, it will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement.

Voting Shares of Company Common Stock Held Through the 401(k) Plan

If you participate in the Company’s 401(k) retirement savings plan (which we refer to as the “401(k) Plan”) and hold shares in your plan account, you may vote the number of shares credited to your account as of the record date. You should receive instructions from the 401(k) Plan trustee, Merrill Lynch, Pierce, Fenner & Smith (which we refer to as “Merrill Lynch”), on how to vote your shares of Company common stock held in the 401(k) Plan. You must provide Merrill Lynch with instructions on how to vote your shares. Only the trustee may vote your plan shares. You may not vote shares held in the 401(k) Plan by returning a proxy card directly to the Company or by voting in person at the special meeting.

23

If you do not instruct the 401(k) Plan trustee, Merrill Lynch, as to how to vote your shares held in the 401(k) Plan, Merrill Lynch may vote your shares in accordance with its fiduciary obligations under the Employee Retirement Income Security Act of 1974, as amended.

Voting of Proxies; Incomplete Proxies

If you submit a proxy, regardless of the method you choose to submit such proxy, the individuals named on the enclosed proxy card, and each of them, with full power of substitution, will vote your shares of Company common stock in the way that you indicate. When completing the Internet or telephone processes or the proxy card, you may specify whether your shares of Company common stock should be voted for or against, or abstain from voting, on all, some or none of the specific items of business to come before the special meeting.

All shares represented by valid proxies that the Company receives through this solicitation, and that are not revoked, will be voted in accordance with your instructions on the proxy card. If you properly sign your proxy card but do not mark the boxes showing how your shares of Company common stock should be voted on a matter, the shares of Company common stock represented by your proxy will be voted in accordance with the recommendations of the Company board, which, as of the date of this proxy statement, are “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal.

Deadline to Vote by Proxy

Please refer to the instructions on your proxy card or voting instruction card to determine the deadlines for submitting your proxy over the Internet or by telephone. If you choose to submit a proxy by mailing a proxy card, your proxy card should be mailed in the enclosed postage-paid return envelope and must be received by our Corporate Secretary by 5:00 p.m., central time, on February 28, 2019.

Revocation of Proxy

If you are a shareholder of record of shares of Company common stock, you may revoke a proxy by:

If you are a “street name” holder of shares of Company common stock, you may change your vote by submitting new voting instructions to your bank, broker or other holder of record or obtaining a legal proxy and voting in person at the special meeting. You must contact the record holder of your shares to obtain instructions as to how to change your proxy vote.

If you hold your shares of Company common stock in the 401(k) Plan, you should contact the plan trustee, Merrill Lynch, to obtain instructions as to how to change your proxy vote.

24

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed for the purpose of soliciting additional proxies if there are insufficient votes at the time of the special meeting to approve the merger proposal. In the event that there is present, in person or by proxy, sufficient favorable voting power to secure the vote of the Company shareholders necessary to approve the merger proposal, the Company does not anticipate that it will adjourn or postpone the special meeting, unless it is advised by counsel that such adjournment or postponement is necessary under applicable law to allow additional time for any disclosure. Any adjournment or postponement of the special meeting for the purpose of soliciting additional proxies will allow the Company shareholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned or postponed.

Solicitation of Proxies

The Company is soliciting your proxy in conjunction with the merger. The Company will bear the cost of soliciting proxies from you. In addition to solicitation of proxies by mail, the Company will request that banks, brokers and other holders of record send proxies and proxy materials to the beneficial owners of Company common stock and secure their voting instructions.

THE MERGER

This discussion of the merger is qualified in its entirety by reference to the merger agreement, which is attached to this proxy statement as Annex A. You should read the entire merger agreement carefully as it is the legal document that governs the merger.

Terms of the Merger

The Company board has unanimously approved the merger agreement and the execution, delivery and performance of the merger agreement and the transactions contemplated by the merger agreement, including the merger. Upon the terms and subject to the conditions set forth in the merger agreement, Merger Sub, a wholly owned subsidiary of Parent, will merge with and into the Company, so that the Company will be the surviving corporation in the merger and a wholly owned subsidiary of Parent. Upon the consummation of the merger, the separate corporate existence of Merger Sub will cease.

At the effective time, each share of Company common stock issued and outstanding immediately prior to the effective time (except for excluded shares) will be converted into the right to receive the merger consideration. For a discussion of the treatment of awards outstanding under the Company stock plans as of the effective time, see “The Merger Agreement—Treatment of Company Equity Awards.”

The Company shareholders are being asked to adopt the merger agreement. See “The Merger Agreement” for additional and more detailed information regarding the legal documents that govern the merger, including information about conditions to the consummation of the merger and provisions for terminating or amending the merger agreement.

Background of the Merger

Set forth below is a description of what we believe are the material aspects of the background and history of the merger. This description may not contain all the information that is important to you. The Company encourages you to read carefully the entirety of this proxy statement, including the merger agreement attached as Annex A to this proxy statement, for a more complete understanding of the merger.

This description begins in August 2015 with the Company’s exploration of strategic alternatives that led to a process in which the Company was marketed to potential acquirers and covers the background and history of the various events following that time and leading to the signing of the merger agreement, including, among other things, the signing and termination of a merger agreement (which we refer to as the “Ultra merger agreement”) with Ultra Electronics Holdings plc (which we refer to as “Ultra”). The section below entitled “—Initial Exploration of Strategic Alternatives; Transaction with Ultra,” which covers the start of such process until the signing of the Ultra merger agreement, is substantially identical to the section entitled “Background of the Merger” contained in the proxy statement filed by the Company in connection with the proposed merger with Ultra. For the background and history relating to the merger that arose following the signing of the Ultra merger agreement, please see the section below entitled”—Developments Following Execution of Ultra Merger Agreement,” beginning on page 59.

The Company board and Company management regularly review and assess the Company’s business strategies and objectives, and the Company board regularly reviews and discusses the Company’s performance, risks and opportunities, all with the goal of enhancing value for the Company’s shareholders.

Initial Exploration of Strategic Alternatives; Transaction with Ultra

In August 2015, the Company board, with the assistance of Company management, reviewed the status and performance of the Company’s previously announced strategic growth plan for 2015 through 2020 (which we

26

refer to as the “2020 Vision”) and, as a part of such review, considered the possibility of potential strategic and financial alternatives that might be available to the Company. As part of its review of the 2020 Vision, the Company board heard presentations from two nationally-recognized middle market investment banks regarding the 2020 Vision and the Company’s strategic alternatives. Neither investment bank had been retained by the Company to perform a review of the Company’s strategic alternatives and the investment banks based their analyses solely on publicly available information.

On September 2, 2015, the Company board held a telephonic meeting at which, as a result of its review of the 2020 Vision and in light of the possibility that Cary B. Wood, the President and Chief Executive Officer of the Company at such time, might have an interest in partnering with a potential financial buyer of the Company, the Company board created a special committee of independent directors of the Company board (which we refer to as the “special committee”). The Company board designated Joseph J. Hartnett, the Chairman of the Company board at such time, and directors James D. Fast, Charles R. Kummeth, David P. Molfenter, James R. Swartwout and Frank A. Wilson as the members of the special committee. The special committee was delegated the power of the Company board to, among other things, review the Company’s strategic alternatives and make a recommendation to the Company board regarding the Company’s strategic alternatives. The special committee was authorized to retain its own advisors, including financial advisors and legal counsel, to assist it in discharging its duties.

From September 2, 2015 through September 11, 2015, after seeking the input of the members of the special committee, Mr. Hartnett and Mr. Swartwout researched and reviewed and interviewed representatives of various law firms to identify potential legal counsel to be retained by the special committee to assist it in discharging its duties.

On September 18, 2015, the special committee held a telephonic meeting. Upon the recommendation of Messrs. Hartnett and Swartwout, the special committee voted to retain Mayer Brown LLP (which we refer to as “Mayer Brown”) to serve as its legal counsel.

On September 22, 2015, the special committee held a telephonic meeting at which representatives of Mayer Brown were present. During the meeting, representatives of Mayer Brown discussed the responsibilities the special committee had been charged with by the Company board and reviewed with the members of the special committee their fiduciary duties under applicable law. In addition, representatives of Mayer Brown discussed expected next steps in the process, including the retention by the special committee of a financial advisor to assist the special committee in exploring strategic alternatives. In addition, representatives of Mayer Brown discussed considerations in addressing any potential actions by Mr. Wood and other members of the Company management team to seek third-party support for a potential proposal to acquire control of the Company.

On September 30, 2015, Mr. Wood delivered to the Company board a preliminary, non-binding proposal contemplating that he and Michael W. Osborne, Senior Vice President, Corporate Development of the Company at such time, and certain unspecified financial partners would acquire the Company at an unspecified cash price. The proposal was subject to, among other things, obtaining financing, completion of due diligence with results satisfactory to the financial partners in their sole discretion and negotiation of definitive transaction agreements.

On October 2, 2015, the special committee held a telephonic meeting at which representatives of Mayer Brown were present. During the meeting, a representative of Mayer Brown outlined the terms of the September 30, 2015 proposal sent by Mr. Wood and the special committee discussed the contents of a proposed letter to be sent by the special committee responding to Mr. Wood. Mr. Hartnett also updated the special committee on the process that he and Mr. Swartwout had been following to identify a list of potential financial advisors for the special committee’s consideration, including an initial outreach process conducted by Mayer Brown to eight financial advisors on a “no-names” basis to gauge each financial advisor’s interest in potentially representing the special committee to assist it in exploring strategic alternatives and obtain background on each financial advisor’s expertise and experience for such an assignment. The special committee directed Messrs. Hartnett and Swartwout to continue the process of identifying potential financial advisors to represent the special committee.

27

On October 5, 2015, Mr. Hartnett, on behalf of the Company board and the special committee, sent to Mr. Wood a letter acknowledging receipt of Mr. Wood’s proposal dated September 30, 2015 and stating that because the special committee had not yet authorized the exploration of an acquisition of the Company, the Company would not be moving forward to entertain Mr. Wood’s proposal at that time. The letter went on to state that in the event that the special committee were to authorize an exploration of an acquisition of the Company, the special committee would notify Mr. Wood of such development. Ultimately, Mr. Wood never submitted another proposal to acquire the Company.

On November 4, 2015, the special committee held a meeting at the Company’s corporate headquarters at which representatives of Mayer Brown were present. During the meeting, representatives of Mayer Brown discussed their observations regarding the joint venture agreement (which we refer to as the “ERAPSCO agreement”) between Sparton DeLeon Springs, LLC, a subsidiary of the Company (which we refer to as “SDS”) and UnderSea Sensor Systems, Inc., a subsidiary of Ultra (which we refer to as “USSI”) under which SDS and USSI are 50/50 partners in a joint venture (which we refer to as the “ERAPSCO JV”). The ERAPSCO JV allows SDS and USSI to combine their own unique and complementary backgrounds to jointly develop and produce U.S. derivative sonobuoy designs for the United States Navy (which we refer to as the “Navy”) as well as for foreign governments that meet Department of State licensing requirements. Representatives of Mayer Brown provided their views on, among other things, the provisions of the ERAPSCO agreement that restrict each party from certain transfers of their respective interests in the ERAPSCO JV, unless the party seeking to make such a transfer first offers the other party the opportunity to purchase such interest (which we refer to as the “ERAPSCO transfer provisions”). Mr. Hartnett also updated the special committee on the process that he and Mr. Swartwout had been following to identify a list of four financial advisors for the special committee to meet with and interview in-person in order to make a final selection of a financial advisor to advise the special committee. Mr. Hartnett described to the special committee the four financial advisors that he and Mr. Swartwout recommended for in-person meetings and, after discussion, the special committee approved their recommendation and directed Messrs. Hartnett and Swartwout to schedule in-person meetings with representatives of those financial advisors.

On November 18 and November 19, 2015, Messrs. Hartnett, Fast, Molfenter and Swartwout held in-person meetings in Rosemont, Illinois with representatives of each of the four financial advisors approved by the special committee. After discussion and consideration by Messrs. Hartnett, Fast, Molfenter and Swartwout, each of Wells Fargo Securities and a middle-market financial advisor (which we refer to as “Financial Advisor A”) were asked to submit a draft of a letter agreement pursuant to which it would be engaged to act as financial advisor to the special committee.

On November 30, 2015, Messrs. Hartnett, Fast, Molfenter and Swartwout conducted a conference call with representatives of Wells Fargo Securities to discuss Wells Fargo Securities’ draft form of engagement letter and requested that Wells Fargo Securities submit a revised draft engagement letter reflecting their comments and discussion.

On December 1, 2015, the special committee held a telephonic meeting at which representatives of Mayer Brown were present. During the meeting, Mr. Hartnett updated the special committee on activities related to the search for and engagement of a financial advisor for the special committee. The special committee supported the selection of Wells Fargo Securities and Financial Advisor A for continued consideration and authorized Messrs. Hartnett, Fast, Molfenter and Swartwout to continue their evaluation, including the negotiation of an acceptable form of engagement letter with each of Wells Fargo Securities and Financial Advisor A, until they were prepared to recommend a financial advisor to the special committee and submit a draft engagement letter for the recommended financial advisor for approval of the special committee.

On December 2, 2015, Wells Fargo Securities submitted to the special committee a revised draft of its engagement letter.

28

From December 3 through December 29, 2015, representatives of the Company, Wells Fargo Securities and Mayer Brown negotiated the terms of Wells Fargo Securities’ engagement letter to act as financial advisor to the special committee. During this period, Mr. Hartnett provided periodic updates to the special committee on the progress of the negotiations of the Wells Fargo Securities engagement letter and the engagement letter for Financial Advisor A, a revised draft of which was received on December 7, 2015.

On December 14, 2015, in light of the possibility that the special committee might retain Wells Fargo Securities to serve as its financial advisor, Mayer Brown sent to Mr. Hartnett a waiver letter containing an acknowledgement by the special committee that Mayer Brown has represented, and continues to represent, Wells Fargo Securities and its affiliates with respect to matters other than its representation of the special committee and the letter provided that the special committee consents to Mayer Brown continuing to represent the special committee, notwithstanding such representations of Wells Fargo Securities and its affiliates.

On December 29, 2015, on the recommendation of Messrs. Hartnett, Fast, Molfenter and Swartwout, the special committee approved the retention of Wells Fargo Securities to serve as its financial advisor to assist the special committee in exploring strategic alternatives and authorized Mr. Hartnett to execute the Wells Fargo Securities engagement letter that had been negotiated.

On December 31, 2015, the special committee, Wells Fargo Securities and the Company executed the Wells Fargo Securities engagement letter.

On January 5, 2016, representatives of Wells Fargo Securities attended a management presentation at the Company’s corporate headquarters. During the presentation, senior management of the Company reported on the state of the Company’s business and strategy, including the 2020 Vision and key value drivers the Company was pursuing.

On January 8, 2016, the special committee held a telephonic meeting at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities reviewed and discussed the Company’s business plan and strategy with the special committee. In addition, the representatives of Wells Fargo Securities reviewed and discussed with the special committee a preliminary list of companies that might potentially be interested in acquiring one or more of the Company’s operations in the event that the Company were to consider divesting part or all of its operations in the future. In addition, the special committee approved the waiver letter that Mayer Brown had sent Mr. Hartnett on December 14, 2015 and directed Mr. Hartnett to execute such waiver letter.

On January 10, 2016, Mr. Kummeth received a telephone call from a representative of a middle market private equity fund focused on the healthcare industry (which we refer to as “Party A”) inquiring about a potential “go-private” acquisition of the Company.

On January 13, 2016, Mr. Kummeth received a follow-up email from the representative of Party A that had contacted him on January 10, 2016 reiterating Party A’s interest in discussing a potential “go-private” acquisition transaction of the Company. In connection with such inquiry, Mr. Kummeth directed the representative of Party A to contact Mr. Hartnett, as chairman of the Company board. The representative of Party A contacted Mr. Hartnett by email later that day to express Party A’s interest in discussing a potential “go-private” acquisition of the Company.

On January 18, 2016, Mr. Hartnett responded by email to the representative of Party A that had sent him the email expressing Party A’s interest in discussing a potential “go-private” transaction of the Company. In his response, Mr. Hartnett thanked the representative of Party A for his email and indicated that the Company board continues to focus on the best path forward for creating value for the Company’s shareholders and that if there is an appropriate time for such a conversation with his organization, the Company board would keep Party A in mind.

29

On January 28, 2016, the special committee held a telephonic meeting at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, Messrs. Kummeth and Hartnett reported to the special committee their communications with the representative of Party A. The special committee also discussed the process for having Company management produce a five-year forecast that Wells Fargo Securities could use for purposes of assisting the special committee in evaluating strategic alternatives. The special committee decided that such forecast would be subject to the review of the special committee and would not be authorized for use by Wells Fargo Securities unless and until approved by the special committee.

On February 5, 2016, Mr. Wood resigned as the President and Chief Executive Officer of the Company and as a member of the Company board, effective as of such date and Mr. Osborne left the Company, also effective as of such date. Also on February 5, 2016, the Company board appointed Mr. Hartnett as interim President and Chief Executive Officer of the Company and Mr. Hartnett resigned as Chairman of the Company board and as a member of the audit committee of the Company board but remained on the Company board as a director and as a member of the special committee. Finally, on February 5, 2016, the Company board appointed Mr. Swartwout to serve as Chairman of the Company board.

On February 8, 2016, Rakesh Sharma, Chief Executive of Ultra, contacted Mr. Swartwout by telephone. During the call, Mr. Sharma expressed an interest in a potential acquisition of the Company’s sonobuoy business. Mr. Swartwout and Mr. Sharma discussed certain potential tax implications of such a transaction as well as matters relating to the Navy, ECP’s largest customer. Mr. Swartwout concluded by telling Mr. Sharma that if the Company were to consider such a transaction, the Company would contact Mr. Sharma first.

On February 9, 2016, a representative of an aerospace and defense company contacted Mr. Hartnett by email regarding a potential strategic transaction with the Company. Mr. Hartnett responded to such representative by email in which he indicated that the Company board continues to focus on the best path forward for creating value for the Company’s shareholders and that if there is an appropriate time for a conversation with his organization regarding a strategic transaction, the Company board would keep his organization in mind. Ultimately, this party did not execute a non-disclosure agreement with the Company or make a proposal to acquire the Company.

On March 8, 2016, the special committee held a meeting at the Company’s corporate headquarters at which representatives of Wells Fargo Securities and Mayer Brown were present, as well as Joseph G. McCormack, Senior Vice President and Chief Financial Officer of the Company and other members of the Company’s senior management. During the meeting, representatives of Wells Fargo Securities reviewed and discussed with the special committee the Company’s historical financial performance, and the historical prices at which its common stock had traded. In addition, the special committee, with the assistance of representatives of Wells Fargo Securities, reviewed and discussed management’s status quo financial forecast plan and the key considerations in evaluating the risks in achieving that plan. Also, representatives of Wells Fargo Securities provided preliminary financial analysis with respect to the Company and described certain strategic alternatives available to the Company, including continuing to execute management’s status quo financial forecast plan, and certain execution and process considerations related thereto, and a possible acquisition of the Company or its business segments by one or more third parties. Upon the conclusion of those discussions, the representatives of Wells Fargo Securities and Mr. McCormack and other members of the Company’s senior management left the meeting and the special committee adopted resolutions recommending to the Company board that the Company proceed to conduct a process (which we refer to as the “marketing process”) to identify parties interested in purchasing or engaging in a merger or other strategic transaction with (i) the Company, (ii) MDS or (iii) the Company as it would exist after a divestiture of MDS, and to identify and determine the price and other terms and conditions upon which any such parties would be willing to consummate any such transactions. The special committee also resolved to recommend to the Company board that the Company board establish a new committee (which we refer to as the “process committee”) comprised of Messrs. Hartnett, Molfenter and Swartwout to conduct the marketing process. The process committee would be assisted and advised by Wells Fargo Securities and Mayer Brown. Such committee would have authority, among other things, to negotiate and execute non-disclosure,

30

standstill and other preliminary agreements and to negotiate purchase agreements, merger agreements and other applicable definitive transaction agreements, except that the process committee would not have the power or authority to authorize the Company to enter into any sale or other business combination transaction or any agreement obligating the Company to consummate any such transaction. Finally, the special committee adopted a resolution to recommend to the Company board that the Company issue a press release announcing that the Company board is considering a range of strategic alternatives with the goal of identifying the best way to enhance shareholder value. Immediately following the adjournment of the meeting of the special committee, the Company board met and adopted resolutions implementing all of the special committee’s recommendations. While not all members of the Company board were members of the process committee, meetings of the process committee were open to all members of the Company board that would like to attend, and often members of the Company board that were not members of the process committee attended meetings of the process committee.

On March 10, 2016, Engine Capital, L.P., Norwood Capital Partners, LP and certain of their respective affiliates (which we collectively refer to as the “Engine Group”) filed a Schedule 13D with the SEC disclosing, in the aggregate, ownership of approximately 6.9% of the outstanding shares of Company common stock. In its Schedule 13D, the Engine Group stated that it had entered into an agreement to, among other things, undertake a plan of action at the Company aimed at enhancing shareholder value, which plan may include, but not be limited to, proposals relating to the Company’s operations, cost and capital allocation, strategic alternatives, the calling of special meetings, and/or reconstitution of the Company board.

On March 16, 2016, Mr. Swartwout contacted Mr. Sharma to inform him that later that day the Company would be issuing a press release announcing that the Company board had been exploring strategic alternatives, with the goal of identifying the best way to enhance shareholder value. Mr. Swartwout also told Mr. Sharma that the Company would like to begin discussions with Ultra in connection with a potential transaction and would like to provide confidential information to Ultra to facilitate those discussions. To that end, Mr. Sharma requested that the Company send to Ultra a draft of a non-disclosure agreement under which the Company would provide certain non-public information to Ultra to facilitate Ultra in making an acquisition proposal.

Later on March 16, 2016, the Company issued a press release announcing that the Company board had been exploring strategic alternatives, with the goal of identifying the best way to enhance shareholder value. The press release stated that Wells Fargo Securities had been retained as financial advisor and that Mayer Brown had been retained as legal advisor to assist in the process.

On March 17, 2016, at the request of the Company board, representatives of Wells Fargo Securities called representatives of Ultra to discuss exploring strategic alternatives with Ultra. During the call, as authorized by the Company board, the representatives of Wells Fargo Securities informed Ultra that a sale of ECP to Ultra might not be financially attractive to the Company, given the potential tax impact on the Company that would result from such a transaction. As directed by the Company board, the representatives of Wells Fargo Securities emphasized that the more straightforward course of action would be an acquisition of the Company in its entirety by Ultra, but the Company board was open to considering other alternatives if superior value could be achieved for the Company’s shareholders.

On March 18, 2016, the process committee held a telephonic meeting. During the meeting, the process committee reviewed and discussed a proposed preparation and marketing timeline, including the assembling of documents for the data room, the preparation of a carve-out audited financial statement for MDS and the preparation of a quality of earnings analysis that would present ECP and MDS as standalone businesses and address corporate costs.

On March 28, 2016, the process committee held a telephonic meeting during which it reviewed and approved a proposal from a nationally recognized accounting and advisory firm to perform a quality of earnings report for the Company and its subsidiaries and a proposal for the Company’s outside auditors to prepare audited carve-out financial statements for MDS.

31

On April 1, 2016, the process committee held a telephonic meeting during which it reviewed the progress of the preparation of the quality of earnings report for the Company and its subsidiaries and preparation of the audited carve-out financial statements for MDS.

On April 18, 2016, the process committee held a telephonic meeting during which it reviewed and approved certain proposed changes to the latest draft of the non-disclosure agreement received from Ultra and reviewed and discussed an updated timeline for the marketing process.

On April 22, 2016, as requested by the process committee, representatives of Wells Fargo Securities called representatives of Ultra to discuss the possibility of Ultra proposing to acquire the Company and the Company board’s process of exploring strategic alternatives. During the call, a representative of Ultra stated that Ultra was not interested in acquiring MDS, but that Ultra would be open to considering an acquisition of the entire Company.

On April 27, 2016, the Company issued a press release announcing that as part of its previously announced exploration of strategic alternatives, the Company board had authorized Wells Fargo Securities to conduct a process to identify parties interested in acquiring the entire Company.

On April 28, 2016, the Company board held a meeting at its corporate headquarters at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities updated the Company board on the status of the marketing process. The representatives of Wells Fargo Securities noted that Baker Tilly Virchow Krause, LLP had commenced work on a quality of earnings report for the Company and its subsidiaries. Representatives of Wells Fargo Securities also discussed the status of the five-quarter forecast and five-year projections being prepared by Company management as well as the current status of the confidential information package regarding the Company to be used in the initial stage of the marketing process. Wells Fargo Securities also reviewed and discussed the 15 potential strategic buyers and 20 potential financial buyers that had to date reached out to Wells Fargo Securities to express an interest in a potential strategic transaction with the Company.

On May 4, 2016, the Company announced that it had entered into an agreement with the Engine Group pursuant to which Alan L. Bazaar and John A. Janitz were appointed to the Company board. Under the agreement, the Engine Group agreed, among other things, to vote its Company shares in support of all of the Company’s director nominees, including both Messrs. Bazaar and Janitz, at the Company’s 2016 annual meeting of shareholders and to abide by customary standstill provisions until January 1, 2017. In addition, under the terms of the agreement, Mr. Janitz and Mr. Bazaar were each appointed to the process committee and the special committee, among other committee appointments.

On May 9, 2016, Ultra Electronics Limited, a subsidiary of Ultra, and the Company entered into a non-disclosure agreement.

On May 11, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of preparations for the marketing process and the timeline for the marketing process. After discussion, the process committee authorized Wells Fargo Securities to contact the 82 potential strategic buyers, including Ultra, that Wells Fargo Securities had identified to the process committee regarding a potential strategic transaction with the Company and to send interested parties a form of non-disclosure agreement approved by the process committee so that the Company could provide certain non-public information to interested parties to facilitate their making of acquisition proposals. In addition, a sub-committee comprised of Mr. Hartnett and Mr. Swartwout was formed to oversee and administer, with the advice of counsel, the negotiation and execution of non-disclosure agreements with potential buyers. The form of non-disclosure agreement approved by the process committee contained customary provisions, including standstill provisions that, for a period of eighteen months, prohibit the counterparty, without the prior written

32

consent of the Company board, from participating in a proposal for the Company either publicly or privately or from asking the Company to amend or waive such standstill provisions (often referred to as a “don’t ask, don’t waive” provision), except that the counterparty may ask the Company to amend or waive the standstill provisions (i) after the Company enters into a definitive agreement with respect to (or has recommended that Company shareholders accept or approve) a transaction involving the acquisition of all or a majority of the Company’s outstanding equity securities or all or substantially all of the Company’s assets and (ii) in order to make a proposal for the Company to the Company board on a confidential basis.

From May 2016 through July 2016, representatives of Wells Fargo Securities contacted the 81 potential strategic buyers, other than Ultra, which had already been contacted, and sent the process committee-approved form of non-disclosure agreement to the 46 strategic buyers that expressed an interest in exploring a strategic transaction with the Company.

On June 3, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities provided an update on the status of the confidential information package regarding the Company and its businesses (which we refer to as the “CIP”), the status of the strategic buyer outreach process authorized by the process committee and the timeline for the marketing process. After discussion, the process committee authorized Wells Fargo Securities to contact the 98 potential financial buyers that Wells Fargo Securities had identified to the process committee regarding a potential strategic transaction with the Company and to send any interested parties the process committee-approved form of non-disclosure agreement so that the Company could provide certain non-public information to interested parties to facilitate their making of acquisition proposals.

From June 2016 through July 2016, representatives of Wells Fargo Securities contacted the 98 potential financial buyers and sent the process committee-approved form of non-disclosure agreement to the 61 financial buyers that expressed an interest in exploring a strategic transaction with the Company.

On June 10, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. At the meeting, the process committee approved the final form of the CIP to be distributed to all prospective buyers that had executed a non-disclosure agreement with the Company.

On June 14, 2016, Mr. Hartnett attended the regularly scheduled meeting of the board of directors of the ERAPSCO JV at USSI’s offices in Columbia City, Indiana. Following the meeting, representatives of Ultra met with Mr. Hartnett and inquired about the Company board’s process of exploring strategic alternatives. Mr. Hartnett told the representatives of Ultra that Wells Fargo Securities would contact Ultra soon about participating in the marketing process. Representatives of Ultra inquired as to whether the marketing process only contemplated the Company board pursuing a sale of the entire Company, to which Mr. Hartnett responded that the Company board was committed to considering all potential transactions that might create value for the Company shareholders. Finally, a representative of Ultra stated that Ultra would expect that the Company would comply with the ERAPSCO transfer provisions as part of the marketing process. Mr. Hartnett responded that it was not clear at this stage of the marketing process whether the ERAPSCO transfer provisions would apply to any transaction the Company board might select to pursue but that in any event the Company would comply with all of its obligations under the ERAPSCO agreement.

On June 17, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process and reported that to date 19 strategic buyers and 15 financial buyers had executed non-disclosure agreements and received the CIP. In addition, at the meeting, the process committee approved the form of the letter (which we refer to as the “IOI letter”) to solicit initial indications of interest from potential buyers of ECP, MDS or the entire Company. The process committee authorized Wells Fargo Securities to send the approved form of letter to solicit initial

33

indications of interest from potential buyers of ECP, MDS or the entire Company to interested parties with a requested deadline for submissions of initial indications of interest due July 12, 2016.

During the week of June 20, 2016, as instructed, Wells Fargo Securities sent an IOI letter to all potential buyers that received the CIP and had not indicated that they were no longer interested in participating in the marketing process.

On June 24, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Mayer Brown were present. During the meeting, the process committee discussed information provided by Wells Fargo Securities on the status of the marketing process including that, to date, 21 strategic buyers and 28 financial buyers had executed non-disclosure agreements and received the CIP.

On June 29, 2016, the Company board held a meeting at the Company’s corporate headquarters at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities updated the Company board on the status of the marketing process and reported that to date, 83 strategic buyers and 101 financial buyers had been contacted, with 21 strategic buyers and 30 financial buyers executing non-disclosure agreements and receiving the CIP and IOI letter. In addition, 28 potential buyers were still negotiating non-disclosure agreements as of such date. In addition, during the meeting, the Company board discussed the advantages and disadvantages of four potential strategic alternative scenarios: (i) a buyer acquiring the entire Company, (ii) a buyer acquiring the entire Company and thereafter the buyer selling one of the Company’s business segments to a second buyer, (iii) a buyer acquiring one of the Company’s business segments and a second buyer then acquiring the Company, which would own the remaining business segment, with both transactions closing substantially simultaneously and (iv) a buyer acquiring one of the Company’s business segments and at a later time a second buyer acquiring the Company, which would own the remaining business segment. Finally, the Company board noted and considered that since Mr. Wood’s resignation on February 5, 2016, the membership of the Company board and the membership of the special committee were the same and that the responsibilities of special committee were, in effect, being discharged by the Company board. In light of such facts, the Company board adopted resolutions formally rendering the special committee inactive, but not dissolving the special committee so that it would be available in the future in the event the special committee needed to be reactivated later in the marketing process. The resolutions adopted by the Company board also charged the Company board with carrying out the duties previously delegated to the special committee, with Wells Fargo Securities and Mayer Brown to serve as advisors to the Company board, which arrangements were subsequently memorialized in amendments to such advisors’ respective engagement letters.

On July 8, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process and reported that to date 23 strategic buyers and 50 financial buyers had executed non-disclosure agreements and received the CIP, with 18 strategic buyers and 44 financial buyers continuing to participate in or not having affirmatively withdrawn from the marketing process.

On July 12, 2016, Wells Fargo Securities received initial indications of interest from seven strategic buyers, including Ultra, and 14 financial buyers. Nine of the initial indications of interest contained a proposal to acquire the entire Company, with indicative prices ranging from $18.00 to $28.00 per share of Company common stock. Six of the initial indications of interest contained a proposal to acquire ECP, with indicative prices ranging from $220 million to $275 million, on a cash-free, debt-free basis. Eight of the initial indications of interest contained a proposal to acquire MDS, with prices ranging from $90 million to $150 million, on a cash-free, debt-free basis. Ultra’s initial indication of interest contained a proposal to acquire the entire Company for $21.00 per share of Company common stock, which attributed a value of $60 million, on a cash-free, debt-free basis, to MDS and a value of $270 million, on a cash-free, debt-free basis, to ECP. In its initial indication of interest, Ultra also expressed a willingness to work with a potential buyer of MDS that had a higher valuation for MDS, if such a joint bid would result in a proposal that would be more attractive to the Company than Ultra’s proposal. Among

34

the initial indications of interest submitted, a non-U.S.based manufacturer of defense products (which we refer to as “Party B”) submitted a proposal to acquire the entire Company at a price range of $26.00 to $28.00 per share of Company common stock. Party B’s indication of interest also contained a proposal to acquire ECP for $250 million, on a cash-free, debt-free basis. Among the initial indications of interest submitted, an indication of interest was also submitted by a financial buyer (which we refer to as “Party C”) to acquire the entire Company at a price range of $25.00 to $28.00 per share of Company common stock. Party A did not submit an initial indication of interest.

On July 15, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities reviewed and discussed its preliminary financial analyses with respect to the Company and its two business segments. In addition, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process and provided a summary of the financial terms of the initial indications of interest received on July 12, 2016. Mr. McCormack also described for the process committee the tax basis analysis of the Company that had recently been completed. The tax basis analysis indicated that, given the Company’s low tax basis in ECP, a sale of ECP would result in significant tax liability to the Company. After a review and discussion with the assistance of representatives of Wells Fargo Securities, the process committee directed that the 13 potential buyers, including Ultra, that had proposed the highest values be invited to participate in the next stage of the marketing process, which would include management presentations.

On July 20, 2016, Wells Fargo Securities received an initial indication of interest from a strategic buyer to acquire ECP for $300 million, on a cash-free, debt-free basis.

On July 22, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including the schedule for management presentations to the potential buyers invited to participate in the next stage of the process. In addition, the process committee approved the potential buyer that submitted its initial indication of interest on July 20, 2016 for advancement to the next stage of the marketing process.

On July 23, 2016, Wells Fargo Securities received an initial indication of interest from a strategic buyer to acquire ECP for $320 million, on a cash-free, debt-free basis. The strategic buyer was invited to advance to the next stage of the marketing process.

On July 25, 2016, at the Company’s corporate headquarters, Mr. Hartnett and other members of Company management gave a management presentation to Ultra regarding the Company, its business segments and operations and its historical and projected financial performance.

From July 26, 2016 through August 12, 2016, Mr. Hartnett and other senior management of the Company gave 14 management presentations at the Company’s corporate headquarters to the other potential buyers that advanced to the next stage of the process.

On July 28, 2016, Wells Fargo Securities received a revised initial indication of interest from a strategic buyer that had not been invited to advance to the next stage in the marketing process. The strategic buyer’s revised proposal was to acquire ECP following the sale of MDS for $325 million on a debt-free basis. The strategic buyer was invited to advance to the next stage of the marketing process.

On July 29, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including the schedule for management presentations to the potential buyers invited to participate in the next stage of the process.

35

During the week of August 8, 2016, the 15 potential buyers still participating in the marketing process were granted access to limited due diligence materials regarding the Company and its businesses via an online virtual data room.

On August 12, 2016, Wells Fargo Securities sent to the 15 potential buyers still participating in the marketing process a letter requesting the submission by August 19, 2016 of revised indications of interests to acquire the entire Company or one of its business segments.

On August 19, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including with respect to the expected submission later in the day of revised indications of interest from the potential buyers participating in the marketing process.

On August 22, 2016, Mr. Hartnett spoke to Mr. Sharma by telephone regarding Ultra’s participation in the current stage of the marketing process and the next stages in the process.

From August 19 through August 23, 2016, Wells Fargo Securities received revised indications of interest from four strategic buyers, including Ultra, and seven financial buyers. Six of the revised indications of interest contained a proposal to acquire the entire Company, with prices ranging from $19.50 to $28.00 per share of Company common stock. Four of the revised indications of interest contained a proposal to acquire ECP, with prices ranging from $235 million on a cash-free, debt-free basis to $325 million, on a debt-free basis, which proposal was structured as an acquisition of the Company following a pre-closing divestiture of MDS. Two of the revised indications of interest contained a proposal to acquire MDS, with prices ranging from $92.5 million to $120 million, on a cash-free, debt-free basis. Ultra’s revised indication of interest contained a proposal to acquire the entire Company at a price of $26.00 per share of Company common stock, contingent upon a sale of MDS for $145 million. To the extent the sale price for MDS would be higher or lower than $145 million, the per share purchase price would be adjusted accordingly to account for the change in the Company’s implied enterprise value. Ultra also stated in its revised indication of interest that it reserved its rights under the ERAPSCO transfer provisions. Among the revised indications of interest submitted, Party B submitted a proposal to acquire the entire Company at a price range of $26.00 to $28.00 per share of Company common stock. Party B’s revised indication of interest also contained a proposal to acquire the Company’s ECP business segment for $250 million, on a cash-free, debt-free basis. Also, among the revised initial indications of interest submitted, Party C submitted a proposal to acquire the entire Company at a price of $26.00 per share of Company common stock.

On August 24, 2016, the Company board held a meeting at its offices at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities reviewed and discussed its preliminary financial analyses with respect to the Company and its two business segments. In addition, a representative of Wells Fargo Securities provided a summary of the revised indications of interest received from August 19, 2016 through August 23, 2016. The Company board discussed the revised indications of interest and noted, among other things, that Ultra’s revised indication of interest reflected a valuation of ECP that was $90 million lower than the highest revised indication of interest for that business segment and a valuation of MDS that was approximately $25 million higher than any other revised indication of interest for that business segment. Wells Fargo Securities also discussed with the Company board the upcoming stages of the marketing process for the parties that continued participating in the process, which would include access for potential buyers to an online virtual data room containing more complete information than that provided to date as well as submission by potential buyers of mark-ups of drafts of definitive transaction documents.

Later in the day on August 24, 2016, Wells Fargo Securities received a revised indication of interest for the acquisition of ECP for a price ranging from $200 million to $220 million, on a cash-free, debt-free basis.

36

On August 25, 2016, Mr. Hartnett spoke to Mr. Sharma by telephone. Mr. Hartnett told Mr. Sharma that based on the revised indications of interest that had been received, Ultra’s revised indication of interest reflected a valuation of ECP that was $90 million lower than the highest revised indication of interest for that business segment and a valuation of MDS that was approximately $25 million higher than that from any other revised indication of interest for that business segment. Mr. Hartnett encouraged Mr. Sharma to have Ultra raise its price to top all other potential buyers and requested that, if the Company decided to pursue an acquisition of the entire Company by another potential buyer, Ultra commit to work as a cooperative joint venture partner with that potential buyer after completion of the transaction. Mr. Sharma responded that Ultra would further consider its most recent indication of interest and would consider submitting a revised indication of interest in the coming days.

On August 30, 2016, Wells Fargo Securities received a revised indication of interest for the acquisition of MDS for $100 million, on a cash-free, debt-free basis.

On September 1, 2016, Ultra submitted to Wells Fargo Securities a revised indication of interest letter. Ultra’s revised indication of interest contained a proposal to acquire the entire Company at a price of $27.00 per share of Company common stock, contingent upon a sale of MDS for $125 million. To the extent the sale price for MDS would be higher or lower than $125 million, the per share purchase price would be adjusted accordingly to account for the change in the Company’s implied enterprise value. Ultra also stated in its revised indication of interest that it reserved its rights under the ERAPSCO transfer provisions.

On September 2, 2016, the process committee held a telephonic meeting at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the revised indications of interest received since the meeting of the Company board on August 24, 2016, including the revised indication of interest received from Ultra on September 1, 2016. After review and discussion with the assistance of representatives of Wells Fargo Securities, the process committee directed that the ten potential buyers, including Ultra, that had proposed the highest values be invited to participate in the next stage of the marketing process.

On September 7, 2016, as directed by the process committee Wells Fargo Securities sent to each of those potential buyers, including Ultra, a process letter that had been approved by the process committee requesting final proposals to acquire the entire Company or one of its business segments by October 7, 2016. The process letters indicated that for potential buyers that would be making proposals to acquire the entire Company or ECP, a form of merger agreement would be sent to them prior to October 7, 2016 for their review and comment and for potential buyers that would be making proposals for MDS, an indicative term sheet setting forth the material terms of an MDS acquisition would be sent to them prior to October 7, 2016 for their review and comment.

On September 12, 2016, a representative of Wells Fargo Securities spoke by telephone with a representative of RBC Capital Markets (which we refer to as “RBC”), a financial advisor to Ultra, regarding the due diligence process. As directed by the process committee, the representatives of Wells Fargo Securities provided RBC with certain information provided by the Company regarding the Company’s corporate cost structure and the likely liabilities that would remain in the Company if the Company were to divest MDS. The representative of RBC informed the representatives of Wells Fargo Securities that Ultra and the Company appeared to have different views on the applicability of the ERAPSCO transfer provisions to the marketing process and that it would be useful for Mr. Hartnett and Mr. Sharma to discuss this matter.

Also on September 12, 2016, additional due diligence materials were made available in the online virtual data room for each of the potential buyers that continued to participate in the process.

On September 13, 2016, Mr. Sharma sent Mr. Hartnett an email indicating that Ultra could not justify spending millions of dollars on due diligence expenses if it did not have exclusivity with the Company regarding a potential strategic transaction and that given the different views of the Company and Ultra as to the applicability

37

of the ERAPSCO transfer provisions to the marketing process, he would like to discuss the issue with Mr. Hartnett by telephone.

On September 14, 2016, Mr. Hartnett spoke with Mr. Sharma by telephone. They discussed the current state of the marketing process, including the fact that other potential buyers were offering higher value than Ultra for a strategic transaction, and their different views as to the applicability of the ERAPSCO transfer provisions to the marketing process. Mr. Hartnett and Mr. Sharma agreed that they would meet, together with their respective financial advisors, in Boston on September 19, 2016 to seek a resolution to the issue relating to the ERAPSCO transfer provisions.

On September 16, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including requests from certain buyers for additional information and site visits at the Company’s facilities. The process committee also discussed issues relating to Mr. Hartnett’s upcoming meeting on September 19, 2016 in Boston with Mr. Sharma and representatives of the Company’s and Ultra’s respective financial advisors.

On September 19, 2016, Mr. Hartnett and Mr. Sharma met in Boston, together with representatives of their respective financial advisors. During the meeting, Mr. Hartnett told Mr. Sharma that a sale of the entire Company was the most likely strategic transaction that would result from the marketing process. Mr. Sharma indicated Ultra’s strong preference that Ultra would only acquire the Company following a sale of MDS or, alternatively, that the Company sell MDS to a buyer and otherwise remain a public company. Mr. Sharma also requested exclusivity in order to remain in the marketing process, to which Mr. Hartnett responded that exclusivity for Ultra was not justified at this time, given the value Ultra had indicated it would be prepared to offer relative to other potential buyers. Mr. Hartnett and Mr. Sharma discussed their respective views on the applicability of the ERAPSCO transfer provisions to the marketing process. Mr. Hartnett indicated to Mr. Sharma that if the Company were to pursue a transaction for the Company or ECP to be acquired by a potential buyer other than Ultra, the Company would provide an opportunity for representatives of Ultra to meet with representatives of such potential buyer prior to the Company entering into a definitive transaction agreement with such potential buyer. Mr. Hartnett and Mr. Sharma agreed that they should consider amending the ERAPSCO agreement to clarify the application of the ERAPSCO transfer provisions to circumstances such as the marketing process, as well as modify other commercial points relating to issues that had arisen in the ERAPSCO JV since the last time the ERAPSCO agreement was amended. Although the Company and Ultra and their respective advisors subsequently negotiated a draft of an amendment of the ERAPSCO agreement, no such amendment or other agreement regarding the applicability of the ERAPSCO transfer provisions was ever executed by the Company, Ultra or their respective subsidiaries.

On September 21, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, Mr. Hartnett, with the assistance of a representative of Wells Fargo Securities summarized for the process committee the matters discussed at the meeting with representatives of Ultra and its financial advisor that they attended in Boston on September 19, 2016, including with respect to working with Ultra and its representatives to amend the ERAPSCO agreement.

On September 21, 2016, as directed by the process committee, Wells Fargo Securities sent to potential buyers that would be making proposals to acquire the entire Company or ECP, including Ultra, a form of merger agreement, which had been prepared by Mayer Brown and approved by the process committee, for their review and comment to be included in their proposals that were due on October 7, 2016. The draft proposed, among other things, (i) a “hell or high water” provision that required the proposed buyer to take any and all actions necessary to obtain antitrust approval for the merger (including offering and agreeing to divestitures with respect to its existing business or the Company’s business and/or litigating to resist or eliminate any order seeking to delay or prohibit the merger), (ii) a termination fee of 2% of the equity value of the transaction, (iii) a right for

38

the Company board to change its recommendation that the Company shareholders vote to adopt the merger agreement (even in the absence of a superior proposal) if the Company board determined in good faith, after consulting with its outside legal counsel, that the failure to do so would be inconsistent with the directors’ fiduciary duties to shareholders. The draft did not condition the closing of the merger on the parties obtaining any regulatory approval, other than clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (which we refer to as the “HSR Act”), or on the potential buyer obtaining financing.

On September 30, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including that several potential buyers continued to appear to be actively conducting due diligence, with Ultra and Party B appearing the most active to date. In addition, two bidders, including Party C, informed Wells Fargo Securities that they were no longer going to participate in the marketing process, while three other potential buyers appeared to only be performing limited due diligence.

On September 30, 2016, as directed by the process committee, Wells Fargo Securities sent to potential buyers, that would be making proposals to acquire MDS, an indicative term sheet, which had been prepared by Mayer Brown and approved by the process committee, setting forth the material terms of an MDS acquisition for their review and comment to be included in their proposals that were due on October 7, 2016. The indicative term sheet provided for, among other things, (i) a transaction for the sale of MDS that would close immediately prior to the consummation of a merger transaction pursuant to which another potential buyer would acquire the Company, (ii) a cash purchase price for MDS on a cash-free, debt-free basis, (iii) certain transition services and supply arrangements to be entered into with the Company, (iv) approval of the transaction by the Company shareholders and (v) the potential buyer to obtain representation and warranty insurance to provide coverage for claims relating to a breach of representation or warranty by the Company or any of its subsidiaries, with no liability of the Company or its subsidiaries for such claims. The indicative term sheet did not condition the closing of the transaction on the parties obtaining any regulatory approval other than clearance under the HSR Act or on the potential buyer obtaining financing.

On October 7, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including that Party C had re-engaged in the marketing process and was expected to submit a proposal on October 7, 2016.

From October 7, 2016 through October 10, 2016, Wells Fargo Securities received revised indications of interest from three potential buyers, including Party C. Two of the revised indications of interest contained proposals to acquire the entire Company and one revised indication of interest contained a proposal to acquire ECP. There were no revised indications of interest with a proposal to acquire MDS. Party C submitted a revised indication of interest containing a proposal to acquire the entire Company for $26.00 per share of Company common stock, with the other updated indication of interest containing a proposal at a price of $21.00 per share of Company common stock. Neither Party C nor the other potential buyer submitted a mark-up of the merger agreement with their updated indications of interest, but Party C included an issues list. The indication of interest containing a proposal to acquire ECP was at a price of $260 million, on a debt-free basis, which proposal was structured as an acquisition of the Company following a pre-closing divestiture of MDS, and did not contain a mark-up of the merger agreement, but did include an issues list.

On October 8, 2016, Mr. Hartnett and Mr. Sharma spoke by telephone. During the conversation, Mr. Sharma informed Mr. Hartnett that Ultra was no longer pursuing a strategic transaction with the Company, but that, given the ERAPSCO JV relationship, Ultra would like for the Company to provide an opportunity for representatives of Ultra to meet with representatives of any potential buyer of the Company or ECP prior to the Company entering into a definitive transaction agreement with such potential buyer.

39

On October 9, 2016, Mr. Hartnett sent Mr. Sharma an email confirming that the Company would provide an opportunity for representatives of Ultra to meet with representatives of any potential buyer of the Company or ECP prior to the Company entering into a definitive transaction agreement with such potential buyer.

On October 14, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including with respect to the three updated indications of interest that were received from October 7, 2016 through October 10, 2016. A representative of Wells Fargo Securities also noted that except for the three potential buyers that submitted a revised indication of interest and Party B, all other potential buyers had withdrawn from the marketing process. In that regard, an updated indication of interest from Party B was expected to be received later on October 14, 2016.

Later on October 14, 2016, Party B submitted an updated indication of interest containing a proposal to acquire the entire Company for $24.00 per share of Company common stock and a mark-up of the merger agreement.

On October 19, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including with respect to discussions with the potential buyers remaining in the marketing process. At the meeting, representatives of Wells Fargo Securities, noting that the number of potential buyers in the process had decreased from ten to four, with Party B and Party C appearing to be the potential buyers most interested in pursuing a potential strategic transaction with the Company, provided additional information regarding investment banking and lending relationships that it or its affiliates had with these remaining bidders. Among other things, a representative of Wells Fargo Securities highlighted for the process committee that (i) Wells Fargo Securities or an affiliate of Wells Fargo Securities is the lead bank for the current credit facility of a subsidiary of Party B and (ii) Wells Fargo Securities or an affiliate of Wells Fargo Securities is a participant in the current credit facility of a consultant that has been advising Party B in its evaluation of a strategic transaction with the Company and that might also provide equity financing to Party B in connection with any such transaction. Representatives of Wells Fargo Securities and Mr. McCormack then left the meeting. The process committee considered whether, in light of Wells Fargo Securities’ relationships with Party B and the consultant, the Company board should retain a second financial advisor in connection with its consideration of strategic alternatives. In response to a request from Party B, the process committee also authorized Wells Fargo Securities to provide Party B with the names of parties that might be interested in acquiring MDS following an acquisition of the entire Company by Party B. Party C had not made a similar request.

On October 24, 2016, as directed by the process committee, Wells Fargo Securities sent Party B and Party C a process letter requesting final proposals to acquire the entire Company to be submitted by November 4, 2016.

On October 28, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including with respect to discussions with Party B and Party C. A representative of Wells Fargo Securities informed the process committee that, as requested by Party B and with the consent of the process committee, Wells Fargo Securities had provided Party B with the names of parties that might be interested in acquiring MDS following an acquisition of the entire Company by Party B. A representative of Wells Fargo Securities stated that Party B was well along in its due diligence but that Party C, whose proposal contemplated obtaining financing from a fund that invests in special situation opportunities (which we refer to “Party D”) had a significant amount of due diligence to complete.

On November 2, 2016, the Company board held a meeting at its corporate headquarters at which representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo

40

Securities updated the process committee on the status of the marketing process, including with respect to discussions with Party B and Party C and the status of their respective due diligence to date. The Company board also discussed updating the then-current 5-year management forecast, such updated forecast to be discussed at a meeting of the Company board to be scheduled for November 8, 2016. The revised 5-year forecast would then be provided to potential buyers for the next round of proposals from Party B and Party C, the due date for which would be extended to November 15, 2016. The Company board noted that the revised 5-year forecast would likely reflect a downward adjustment of financial performance, as compared to the then-current 5-year forecast. After the representatives of Wells Fargo Securities left the meeting, a representative of Mayer Brown described for the Company board the potential conflicts of interest that Wells Fargo Securities might have as a result of the relationships with Party B that it disclosed, in light of Party B being one of only two bidders remaining in the marketing process, to the process committee on October 19, 2016. After discussion, the Company board decided to seek to identify a potential second financial advisor to assist it in the exploration of strategic alternatives.

On November 8, 2016, the Company board held a telephonic meeting at which members of Company management and representatives of Wells Fargo Securities and Mayer Brown were present. Company management presented and discussed a revised 5-year management forecast, which after discussion, the Company board approved, with certain changes, for distribution to Party B and Party C.

On November 14, 2016, the Company board held a telephonic meeting at which representatives of Mayer Brown were present. At the meeting, the Company board discussed the potential conflicts of interest of Wells Fargo Securities that were discussed by the Company board at its November 2, 2016 meeting, in light of Party B being one of only two bidders remaining in the marketing process. After discussion, the Company board decided to engage a second financial advisor to advise it in evaluating potential strategic alternatives available to the Company, including the marketing process, and provide a fairness opinion in the event the Company board decides to pursue a strategic transaction.

On November 15, 2016, Party C submitted a proposal to acquire the entire Company for $26.25 per share of Company common stock. The proposal contained a detailed list of due diligence requests and a letter from a national investment bank stating that it was “highly confident” that an acquisition of the Company could be financed in the then-current debt markets. Party C’s proposal also contained a mark-up of the merger agreement.

On November 16, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including with respect to the proposal received from Party C on November 15, 2016. The representative of Wells Fargo Securities stated that Wells Fargo Securities understood that Party C was an uncommitted family office fund with investors that included several prominent families in the United States. The process committee asked Wells Fargo Securities to follow up with Party C to obtain information regarding the identities of financing sources for Party C’s proposal. The process committee decided to not make a decision on how to proceed with Party C until it learned whether Party B would submit a proposal.

On November 17, 2016, Party B submitted a proposal to acquire the entire Company for $21.50 per share of Company common stock. The proposal contained a detailed list of due diligence requests and requested a meeting with Ultra to discuss the ERAPSCO JV and agree on maintaining the ERAPSCO JV without material change through 2023. Party B also requested exclusivity with the Company for 30 days and included in its proposal a form of the exclusivity agreement it was prepared to execute.

Also on November 17, 2016, Party C sent to Wells Fargo Securities a letter outlining its sources and uses of funds for its proposal that it submitted on November 15, 2016. Also in the letter, Party C indicated that it was important that it be permitted to engage with USSI to discuss the ERAPSCO agreement.

On November 18, 2016, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Mayer Brown were present. During the meeting, Mr. Hartnett updated the process committee

41

on the status of the marketing process, including with respect to the proposal received from Party B on November 17, 2016 and the letter received from Party C on November 17, 2016. After discussion, the process committee decided that Mr. Hartnett and a representative of Mayer Brown would have a conference call with representatives of Party C and its counsel for the purpose of determining the identities of the investors in Party C and the parties providing financing for Party C’s proposal and requesting that Party C submit written equity and debt commitments in connection with the financing of its proposal. Later on November 18, 2016, Mr. Hartnett and a representative of Mayer Brown had a telephone call with representatives of Party C and its counsel, after which Party C sent a letter to Wells Fargo Securities setting forth additional information identifying its sources of financing for its proposal.

On November 18, 2016, with the approval of the Company board, the Company entered into an agreement with Raymond James for Raymond James to serve as a second financial advisor to advise the Company board in evaluating potential strategic alternatives available to the Company, including the marketing process, and provide a fairness opinion in the event the Company board decides to pursue a strategic transaction.

C earlier that day. The process committee decided that Mr. Hartnett would contact Mr. Sharma to determine whether Ultra was amenable to entering into an agreement acceptable to Party C regarding the future conduct of the ERAPSCO JV in the event Party C acquires the Company.

Later on December 16, 2016, Mr. Hartnett spoke to Mr. Sharma by telephone. Mr. Sharma stated that he thought that Ultra and Party C were aligned on the future conduct of the ERAPSCO JV in the event Party C were to acquire the Company and that he thought an agreement reflecting that understanding could be executed. Mr. Sharma stated that he would send a draft of an amendment to the ERAPSCO agreement to reflect the relevant changed terms to memorialize this understanding.

On December 19, 2016, a representative of Ultra sent to Mr. Hartnett a draft of an amendment to the ERAPSCO agreement to reflect changes that Ultra proposed to the terms of the ERAPSCO agreement for the future conduct of the ERAPSCO JV in the event Party C were to acquire the Company.

On December 20, 2016, Mr. Hartnett spoke with a representative of Party C by telephone during which they discussed Ultra’s proposed amendment to the ERAPSCO agreement and they both agreed that Ultra’s proposed amendment was unworkable and did not provide the clarity that Party C sought regarding the future conduct of the ERAPSCO JV in the event Party C were to acquire the Company.

On December 26, 2016, Party C sent to Wells Fargo Securities a letter revising its November 15, 2016 proposal.

The feedback from a representative of Party C and its financial advisor was that Ultra’s proposed amendment to the ERAPSCO agreement appeared to indicate a lack of cooperation from Ultra with Party C with respect to the potential future of the ERAPSCO JV. The process committee, with the assistance of Wells Fargo Securities, Raymond James and Mayer Brown, also discussed whether it was likely that Ultra would react differently to Party B regarding the ERAPSCO JV, should a transaction with Party B be pursued. The process committee decided that Wells Fargo Securities and Raymond James should contact each of Party B and Party C and ask them to provide proposals assuming that there would be no changes to the ERAPSCO agreement or other agreement with Ultra prior to an acquisition of the Company and that the post-acquisition conduct of the ERAPSCO JV would be governed by the ERAPSCO agreement as currently in effect. Representatives of Mayer Brown would be available to discuss their views on the ERAPSCO agreement with representatives of Party B and Party C, to the extent such parties desired to have those discussions.

During the week of January 9, 2017, a representative of RBC contacted a representative of Wells Fargo Securities by telephone and stated that Ultra would not be comfortable with having Party B as a joint venture partner if Party B were to acquire the Company, given that Ultra and Party B are competitors in markets other than sonobuoys.

Mr. Hartnett reported that a meeting with Mr. Sharma, Mr. Hartnett and a representative of Party B would be held at Ultra’s corporate headquarters on January 30, 2017.

Mr. Sharma also acknowledged to Mr. Hartnett and the representatives of Party B that Ultra could not control whether Party B acquired the Company, but under the ERAPSCO agreement, Ultra, like the Company, had the right to terminate the agreement for convenience on 18 months notice and Ultra might exercise that right. Following the meeting, a representative of Party B spoke with Mr. Hartnett and requested a meeting with a representative of the Navy in order to discuss issues relating to the ERAPSCO JV in the event Party B were to acquire the Company.

On February 1, 2017, representatives of Wells Fargo Securities received a telephone call from a representative of an electronic medical device manufacturer (which we refer to as “Party F”).

The Company board discussed the remaining due diligence requests from Party C, including completion of a quality of earnings report and environmental due diligence and the Company board’s need to further understand the financing arrangements being proposed by Party C. The Company board also discussed Party B’s request to meet with representatives of the Navy and the closing condition in Party B’s draft of the merger requiring approval of the Committee on Foreign Investment in the United States (which we refer to as “CFIUS”). The Company board directed Wells Fargo Securities, Raymond James and Mayer Brown to follow-up with Party B and Party C to discuss these issues and decided to hold its next meeting after receipt of Party E’s proposal.

On February 12, 2017, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities and Raymond James updated the Company board on the status of the marketing process, including with respect to proposals from Party B and Party C that had been received on February 6, 2017, including advantages and disadvantages of each proposal, as well as the follow-up actions that the Company board’s advisors had taken as directed by the Company board at its last meeting. A representative of Raymond James stated that neither Party E nor Party F submitted a proposal. Party E stated that following its due diligence, any proposal it would submit would be less than $20.00 per share of Company common stock and

47

it did not view that its bid would be competitive. Party F indicated that it did not have the time and resources to submit a proposal and it believed the per share price it would propose would be low compared to other likely proposals. With regard to Party C’s proposal, Wells Fargo Securities and Raymond James had asked for copies of the equity backstop letter from Party D to support Party C’s bid. After initial resistance, Party C provided a copy of an equity backstop letter from Party D, which a representative of Raymond James described as a letter of support that lacked the terms and conditions of an equity commitment letter. The representative of Raymond James stated that he subsequently asked for details on the terms and conditions of the proposed Party D financing but to date had not received any additional information. As part of the discussion of Party B’s proposal, a representative of Mayer Brown described for the Company board the CFIUS approval process, as well as other defense-related governmental approvals that would be required in a transaction with Party B. After discussion, the Company board decided to pursue exclusivity with Party B and identified the following additional process points to be completed prior to the Company entering into an exclusivity agreement with Party B: (i) Mr. Hartnett would contact a representative of the Navy that oversees the sonobuoy program to discuss a potential acquisition of the Company by Party B, (ii) Mayer Brown would pursue discussions with Party B’s counsel to address key legal matters relating to a definitive agreement, including a reverse break-up fee if regulatory approvals are not obtained and (iii) Wells Fargo Securities and Raymond James would seek additional information from Party B with respect to its ability to finance an acquisition of the Company.

After discussion, the process committee decided that because the most recent price per share offered by Party C remained less than the price offered by Party B, Wells Fargo Securities and Raymond James should attempt to have Party C extend its deadline for obtaining exclusivity with the Company to February 22, 2017 and the Company should continue to seek to sign an exclusivity agreement with Party B.

On February 20, 2017, Party C sent a letter to the Company stating that it would increase its proposed price per share of Company common stock to $24.50, assuming Party C and the Company have entered into a mutually acceptable exclusive negotiation arrangement by February 22, 2017.

Representatives of Mayer Brown also described the status of negotiations of the exclusivity agreement with Party B’s counsel.

Later that day, Mr. Hartnett forwarded the letter to a representative of Party B.

the threat to terminate the ERAPSCO agreement contained in the most recent letter from Ultra. Representatives of Wells Fargo Securities and Raymond James updated the Company board on the status of discussions with Party C’s financial advisors, including with respect to the letter received from Party C earlier in the day and the equity financing to be provided by Party D for an acquisition of the Company by Party C. Given the recent developments reported to the Company board, including Ultra’s threat in its most recent letter to terminate the ERAPSCO agreement in the event that Party B were to be the acquirer of the Company and the significant reduction in Party C’s due diligence requests, the Company board, after discussion with its legal and financial advisors, decided to pursue an acquisition of the Company by Party C, instead of Party B, and grant Party C the 15 business day exclusivity period it requested in order to complete its due diligence and for the parties to work toward the signing of a definitive agreement for Party C to acquire the Company. After discussion, the Company board decided that Mr. Hartnett would contact Mr. Sharma to determine whether Ultra would find Party C an acceptable joint venture partner and representatives of Wells Fargo Securities and Raymond James would reach out to Party C and Party D to seek further information regarding Party C’s proposal, including details regarding the proposed financing arrangements and confirmatory due diligence requirements.

Later on March 13, 2017, Mayer Brown sent to counsel for Party C a draft of an exclusivity agreement. From March 13, 2017 through March 15, 2017, Mayer Brown, counsel for Party C and counsel for Party D negotiated the exclusivity agreement.

On March 15, 2017, the Company, Party C and Party D executed an exclusivity agreement providing for exclusivity through April 5, 2017.

From March 15, 2017 through April 5, 2017, Company management, Wells Fargo Securities and Raymond James had telephone calls with representatives of Party C and its financial advisors and Party D to discuss Party C and Party D’s due diligence review. During this period, representatives of Wells Fargo Securities and Raymond James also had telephone calls with representatives of Party C’s financial advisors and Party D to discuss the financing commitments Party C and Party D were putting in place for an acquisition of the Company. During that period, representatives of Mayer Brown had telephone calls with representatives of counsel to Party D to discuss the draft of the merger agreement.

On March 31, 2017, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities and Raymond James updated the Company board on the status of process with Party C and Party D, including with respect to Party C and Party D’s due diligence requests. A representative of Mayer Brown discussed the most significant issues on the merger agreement raised in discussions with Party D’s counsel and indicated that despite repeated requests, counsel for Party D had not committed to a time table for

50

delivering comments to the merger agreement or the disclosure schedules. With Party C and Party D’s period of exclusivity about to expire, the Company board decided that no extension would be granted until Party C and Party D first committed to a time table for delivering comments to the merger agreement and the disclosure schedules.

On April 5, 2017, representatives of Wells Fargo Securities and Raymond James spoke by telephone to representatives of Party C and its financial advisor and Party D. Representatives of Party D acknowledged that they had not completed their due diligence and were not in a position to provide a date by which they thought they would complete their due diligence. Representatives of Party D stated that during the exclusivity period they had met with representatives of Ultra to discuss the ERAPSCO JV. A representative of Party D stated that based on those discussions, Party C and Party D now believe that Ultra is of the view that Party C and Party D would not be acceptable joint venture partners and they believe that Ultra would not be a cooperative partner with Party C or Party D in the ERAPSCO JV in the event of an acquisition of the Company.

On April 7, 2017, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities and Raymond James updated the Company board on the recent discussions with Party C and its financial advisor and Party D. The Company board considered potential next steps in the marketing process, including (i) continuing with Party C and Party D without granting an extension of exclusivity, (ii) re-engaging with Party B, (iii) seeking to re-engage with other potential acquirers of the Company that had previously withdrawn from the marketing process, (iv) exploring whether to pursue a sale of MDS with a later potential sale of the Company, which would have continued as the owner of ECP, (v) approaching Ultra regarding a potential acquisition of the Company or (vi) concluding the marketing process without a strategic transaction. The Company board discussed and evaluated the various potential next steps and decided to simultaneously continue working with Party C and Party D without granting an extension of exclusivity and seek to re-start discussions with Party B. In addition, it was decided that Mr. Hartnett would contact Mr. Sharma to seek his feedback regarding his meeting with representatives of Party C and Party D.

On April 10, 2017, Mr. Hartnett spoke with Mr. Sharma regarding his discussion with representatives of Party C and Party D. After recounting the issues he had discussed with representatives of Party C and Party D, Mr. Sharma indicated that if Party C and Party D were to withdraw from the marketing process, Ultra would be interested in acquiring the Company.

On April 11, 2017, at the request of the Company board, a representative of Wells Fargo Securities spoke with Mr. Sharma regarding a potential acquisition of the Company by Ultra. During the discussion, Mr. Sharma stated that if Ultra were to acquire the Company, MDS would need to be divested prior to or at the same time that Ultra acquires the Company.

On April 12, 2017, a representative of Wells Fargo Securities spoke again with Mr. Sharma regarding a potential acquisition of the Company by Ultra. Mr. Sharma told the representative of Wells Fargo Securities that Ultra would have to update its financial analysis of the Company before responding with a proposed price per share of Company common stock and would require a period of exclusivity.

On April 14, 2017, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, Mr. Hartnett reported on the recent discussions he had had with Mr. Sharma. In addition, representatives of Wells Fargo Securities and Raymond James updated the Company board on the recent discussions with representatives of Party C and Party D in which Party C and Party D described their remaining due diligence and reiterated that the Company’s relationship with Ultra in the ERAPSCO JV caused them concerns because their discussions with representatives of Ultra did not demonstrate a clear willingness by Ultra to be a cooperative partner with the Company in the ERAPSCO JV following an acquisition of the Company by Party C and Party D. A representative of Wells Fargo Securities recounted the discussions with Mr. Sharma on April 11, 2017 and

51

April 12, 2017 in which Mr. Sharma indicated that Ultra would like to obtain updated financial information and obtain a period of exclusivity. A representative of Wells Fargo Securities also reported regarding a discussion with the financial advisor to Party B in which the financial advisor indicated that Party B would likely not pursue an acquisition of the Company, given the response from Ultra to the possibility of an acquisition of the Company by Party B, including Ultra’s threat to terminate the ERAPSCO agreement in the event of such an acquisition. After discussion, the Company board decided to explore a transaction for a potential acquisition of the Company by Ultra, including a potential contemporaneous divestiture of MDS.

On April 20, 2017, a representative of the Navy forwarded to Mr. Hartnett a copy of a letter received by the Secretary of Defense from Representative Jim Banks, member of the U.S. House of Representatives from the Third District in Indiana, requesting a briefing concerning the measures in place to ensure continuity of sonobuoy supply and the protection of sonobuoy intellectual property from contractors from “non-Five Eyes” nations who might seek to acquire all or a part of the ERAPSCO JV. The Navy asked the Company to provide certain information requested in Representative Banks’ letter, which would be incorporated into the Department of Defense’s response to Representative Banks’ information request.

On April 21, 2017, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. A representative of Wells Fargo Securities reported that Wells Fargo Securities was expecting a proposal from Ultra to acquire the Company later in the day, although Ultra’s financial advisors had said that the price per share of Company common stock would be less than $24.50. Representatives of Wells Fargo Securities and Raymond James reported that at this point Party C and Party D have said they would not be interested in pursuing an acquisition of the Company that did not include ECP, and Party B had not been in recent contact with the Company’s financial advisors.

Later in the day on April 21, 2017, Ultra sent an indication of interest to Wells Fargo Securities to acquire the Company for $23.50 per share of Company common stock. In its letter, Ultra stated that a sale of MDS would not be a condition to Ultra’s acquisition of the Company; however, the letter also stated that Ultra required assistance from the Company’s financial advisor in identifying parties that might be interested in acquiring MDS and that Ultra be permitted to negotiate with those parties. Ultra also requested six weeks of exclusivity with the Company.

On April 25, 2017, Guggenheim Securities, LLC (which we refer to as “Guggenheim”), financial advisor to Ultra, sent to Wells Fargo Securities its initial due diligence request list.

On April 26, 2017, the Company board held a meeting at its corporate headquarters at which Mr. McCormack was present and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present by telephone. A representative of Wells Fargo Securities reported that Party C and Party D had withdrawn from the marketing process, with a representative Party D indicating that if at a later time Party D were to pursue an acquisition of the Company, it would need to conduct an extensive due diligence process because they would need to proceed on the assumption that the ERAPSCO JV would be terminated in connection with an acquisition of the Company. The representative of Party D indicated that under such circumstances, an acquisition of the Company would be at a price per share for Company common stock below Party C and Party D’s current price of $24.50. Representatives of Raymond James and Wells Fargo Securities also reported on recent discussions with Party B’s financial advisor. Party B’s financial advisor informed Raymond James that Party B would consider submitting an updated proposal, which would assume a termination of the ERAPSCO JV in connection with an acquisition of the Company by Party B; however, any such proposal would be at a price per share for Company common stock below Party B’s current price of $24.50. Representatives of Raymond James and Wells Fargo Securities also described for the Company board Ultra’s indication of interest received on April 21, 2017 and noted that Ultra did not ascribe a separate value to MDS in its indication of interest. The Company board decided to have Wells Fargo Securities and Raymond James engage with Ultra’s financial advisor to determine how much value Ultra is ascribing to MDS in its indication of interest and wait to receive Party B’s next proposal.

52

Also on April 26, 2017, the Company sent to the Navy by email its response to the request for information it received from the Navy on April 20, 2017 in connection with Representative Banks’ letter to the Department of Defense.

On April 28, 2017, Ultra sent an updated indication of interest to Wells Fargo Securities that maintained the same terms as the April 21, 2017 indication of interest and ascribed a minimum value for MDS materially below other indications received by the Company from bidders for MDS.

On May 1, 2017, Ultra sent an updated indication of interest to Wells Fargo Securities that maintained the same terms as the April 28, 2017 indication of interest but instead provided for only a four week exclusivity period. The updated indication of interest also provided that Ultra would provide to the Company a list of open due diligence items by the end of the first week of exclusivity and that if a substantial majority of such items were not provided to Ultra by the end of the second week of exclusivity, the exclusivity period would be automatically extended for one to two weeks.

On May 1, 2017, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. A representative of Wells Fargo Securities provided the Company board with an update regarding the updated indication of interest letter from Ultra received earlier in the day. The Company board discussed Ultra’s request for exclusivity for a period of four to six weeks. Representatives of Wells Fargo Securities and Raymond James also reported that representatives of Party B had not replied to their inquiries about whether Party B was willing to submit a revised proposal to acquire the Company. After discussion, the Company board authorized Mr. Hartnett to negotiate an exclusivity agreement with Ultra.

On May 2, 2017, at the request of the Company board, representatives of Wells Fargo Securities and Raymond James sent to Guggenheim and RBC a draft of a document outlining a proposed four week process to allow Ultra to engage with potential MDS buyers before the execution of a merger agreement with the Company.

Later in the day on May 2, 2017, Mayer Brown sent to Arnold & Porter a draft of an exclusivity agreement. From May 2, 2017 through May 10, 2017, Mayer Brown and Arnold & Porter negotiated the exclusivity agreement.

On May 3, 2017, representatives of Wells Fargo Securities and Raymond James discussed with RBC and Guggenheim the proposed four week process to allow Ultra to engage with potential MDS buyers before the execution of a merger agreement with the Company, which process included, with the consent of the Company board, Wells Fargo Securities contacting potential MDS buyers that participated in the marketing process and providing confidential information to and obtaining initial indications of interest from potential MDS buyers and Ultra negotiating definitive purchase agreements with selected potential MDS buyers. Entry by the Company or Ultra into a definitive agreement to acquire MDS would not be a condition to the execution of a merger agreement or the closing of Ultra’s acquisition of the Company. From May 3, 2017 through July 7, 2017, representatives of Wells Fargo Securities, with the consent of the Company board, provided assistance to RBC and Guggenheim in exploring a potential sale of MDS.

On May 10, 2017, the Company and Ultra executed an exclusivity agreement providing for exclusivity through June 7, 2017, except that if by May 22, 2017 the Company shall not have provided Ultra a substantial majority of the due diligence items on a list to be provided by Ultra to the Company no later than May 15, 2017, the exclusivity period would be automatically extended to June 21, 2017. The exclusivity agreement contained provisions permitting the Company and its representatives and advisors to assist Ultra in the process of soliciting proposals from potential buyers of MDS.

On May 17, 2017, representatives of Wells Fargo Securities spoke by telephone with a representative of Guggenheim. The representative of Guggenheim stated that under the listing rules of the United Kingdom Listing Authority (which we refer to as the (“UKLA”), Ultra’s acquisition of the Company would be subject to the approval of Ultra’s shareholders.

On May 19, 2017, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities provided the process committee with an update regarding the solicitation of potential buyers of MDS. In addition, a representative of Wells Fargo Securities reported regarding the progress of Ultra’s due diligence review of the Company since the exclusivity agreement was entered into by the Company and Ultra. A representative of Wells Fargo Securities and a representative of Mayer Brown also reported to the process committee that Ultra’s financial advisor indicated that the approval of the transaction by Ultra’s shareholders would be a closing condition to the transaction. As there remained outstanding a substantial number of Ultra’s due diligence requests, the process committee expected that exclusivity would be extended to June 21, 2017, and exclusivity was so extended to that date.

On May 24, 2017, Arnold & Porter sent to Mayer Brown a revised draft of the merger agreement that had been provided to Ultra on September 21, 2016 in connection with Ultra’s participation in the marketing process.

On May 26, 2017, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. A representative of Wells Fargo Securities updated the process committee on the progress Ultra was making in its due diligence and the structure under which Ultra intended to raise funds to pay the purchase price in the transaction by doing an equity placement, to be completed on the date that the transaction is announced. Representatives of Wells Fargo Securities and Raymond James also reviewed with the process committee the seven initial indications of interest that been submitted for MDS by potential buyers. The purchase prices in such indications ranged from $39 million to $80 million for the sale of MDS, on a cash-free, debt-free basis. The representatives of Wells Fargo Securities and Raymond James told the process committee that, in light of the prices in the initial indications of interest for MDS, they had attempted to obtain from Ultra a higher price per share of Company common stock in the transaction. In response, Ultra refused to raise its price, stating that the MDS sale was not a condition to the transaction and that Ultra was taking the execution risk on selling MDS after it acquires the Company.

On May 31, 2017, a representative of Wells Fargo Securities received an email from an individual representing a publicly listed supplier of aerospace and defense products and systems (which we refer to as “Party G”) seeking to make a proposal to acquire the Company. In accordance with the terms of the exclusivity agreement, the Company notified Ultra of the receipt of this communication.

On June 2, 2017, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. A representative of Mayer Brown discussed key issues raised by counsel for Ultra in its draft of the merger agreement. A representative of Mayer Brown also described the approach that Mayer Brown is taking in the revised draft of the merger agreement that it is preparing, including with respect to provisions related to certainty of closing, among other issues. A representative of Wells Fargo Securities reported on the progress Ultra has been making in its due diligence. He further reported that five of the seven parties that had provided indications of interest in acquiring MDS have been given access to the confidential information the Company has compiled in a virtual online data room and that they will be asked to provide more definitive proposals to the Company’s financial advisors and Ultra’s financial advisors, after additional due diligence has been performed.

On June 4, 2017, representatives of Wells Fargo Securities and Mayer Brown had a conference call with representatives of Guggenheim and RBC and Ultra’s U.K. counsel and outside accountants. During the call, the parties discussed the process and timing for completion of Ultra’s shareholder circular to be sent to its shareholders in connection with the shareholder meeting to be held for Ultra’s shareholders to vote on the transaction as well as the timing for such meeting. In addition, in connection with the preparation of Ultra’s shareholder circular, representatives of Ultra’s outside accountants and counsel described certain information that would be required to be provided to Ultra by the Company.

54

On June 6, 2017, Party G sent to a representative of Wells Fargo Securities a non-binding proposal to acquire the Company for $22.00 to $24.00 per share of Company common stock. In accordance with the terms of the exclusivity agreement, the Company notified Ultra of the receipt of this communication and provided Ultra a copy of the proposal.

On June 9, 2017, a representative of the Company spoke with a representative of Ultra. During the conversation, the representative of the Company described a potential breach by the Company of its financial covenants in its credit agreement for the test period ending on the last day of the Company’s fiscal quarter ending July 2, 2017. The representative of the Company told the representative of Ultra that the Company was working with its creditor banks to have any such potential breach, if it were to occur, waived by such banks.

Also on June 9, 2017, Mayer Brown sent to Arnold & Porter a revised draft of the merger agreement.

On June 12, 2017, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities and Mayer Brown were present. A representative of Wells Fargo Securities reported on progress Ultra and its representatives have made, detailing milestones that Ultra had indicated needed to be achieved prior to executing a merger agreement with the Company, including with respect to Ultra’s remaining due diligence requirements and its drafting and filing with the UKLA of a shareholder circular with respect to the meeting of Ultra shareholders that would be required to be convened to vote on approval of the transaction. The representative also reported that representatives of Ultra’s financial advisors indicated that Ultra currently expects to submit to the Company on June 23, 2017 a letter confirming its price for an acquisition of the Company and setting out its requirements to be satisfied before executing a merger agreement, which letter would be sent following a meeting of Ultra’s board of directors. A representative of Mayer Brown described for the process committee certain considerations and implications of the Company executing a merger agreement with Ultra concurrently with Ultra filing its shareholder circular with the UKLA instead of executing the merger agreement only after the shareholder circular has been approved by the UKLA for mailing to Ultra’s shareholders. The later the date that Ultra would be permitted to hold its shareholders meeting to vote on the transaction, the longer the opportunity the Ultra board would have to, in the exercise of its fiduciary duties, change its recommendation to its shareholders that they approve the transaction. After discussion, the Company board decided to seek to sign a merger agreement with Ultra as soon as possible, even if the shareholder circular shall not have been approved by the UKLA.

On June 13, 2017, at the direction of the process committee and with the consent of Ultra, a representative of Wells Fargo Securities sent to a representative of Party G an email stating that Party G’s proposal had been forwarded to the Company board and that once the Company board had a response to such proposal, Wells Fargo Securities would contact Party G.

He also reported that Ultra indicated that it would send a letter confirming its price per share of Company common stock prior to the process committee’s next meeting. A representative of Mayer Brown advised the process committee on key issues remaining to be resolved in merger agreement negotiations, including with respect to closing certainty and efforts to obtain regulatory approval. The process committee decided to extend the exclusivity period under the Company’s exclusivity agreement with Ultra to June 26, 2017 and authorized Mr. Hartnett to execute an amendment to the exclusivity agreement to grant such extension.

On June 21, 2017, representatives of Wells Fargo Securities and Mayer Brown had a conference call with representatives of Guggenheim, RBC and Ultra’s counsel. On the call, the participants discussed items remaining

55

to be resolved in the merger agreement, including with respect to (i) whether the Ultra shareholder meeting would be held prior to, contemporaneous with or after the Company shareholder meeting, (ii) whether Ultra would obtain the support of certain shareholders through undertakings under which such shareholders would agree to vote to approve the transaction at the Ultra shareholders meeting, (iii) the timing of the filing and the level of efforts in seeking approval of the UKLA for the Ultra shareholder circular to be sent to Ultra’s shareholders in connection with the Ultra shareholders meeting, (iv) Ultra’s level of efforts in pursuing and obtaining all governmental approvals, including clearances under the HSR Act and CFIUS, (v) whether Ultra would have the right to terminate the merger agreement if a governmental authority shall have filed an action seeking to restrain the transaction and (vi) the amounts of the termination fees to be paid by the Company and Ultra if the merger agreement were to be terminated under certain circumstances.

Later in the day on June 21, 2017, representatives of Mayer Brown had a conference call with representatives of Arnold & Porter to negotiate terms of the merger agreement.

On June 22, 2017, Mayer Brown sent to Arnold & Porter a draft of the disclosure schedules to the merger agreement.

Also on June 22, 2017, representatives of Wells Fargo Securities and Raymond James spoke by telephone with representatives of Guggenheim and RBC. During the call, representatives of Wells Fargo Securities and Raymond James, at the direction of the Company board, described a potential breach by the Company of its financial covenants in its credit agreement for the test period ending on the last day of the Company’s fiscal quarter ending July 2, 2017. The representatives of Guggenheim and RBC responded that they did not believe that Ultra would execute the merger agreement if the breach were not to be waived by the creditor banks under the credit agreement.

On June 23, 2017, MergerMarket published an article reporting that the Company and Ultra were in “deep sale discussions.”

On June 24, 2017, in response to the MergerMarket article, as required by the UKLA, Ultra issued a press release confirming it was in advanced discussions to acquire the Company.

On June 26, 2017, in response to the MergerMarket article and Ultra’s press release of June 24, 2017, the Company issued a press release confirming it was in discussions to be acquired by Ultra.

Also on June 26, 2017, Ultra sent to the Company its final offer to acquire the Company for $22.35 per share of Company common stock. Ultra’s final offer was conditioned upon, among other things, the Company’s lenders waiving the Company’s compliance with its debt covenants from signing to closing of the transaction. Ultra also requested that exclusivity be extended to July 10, 2017.

On June 26, 2017, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. A representative of Wells Fargo Securities described the final offer received from Ultra earlier in the day and explained that Ultra

56

believed that the outstanding debt of the company was $12 million higher than the amount it had been assuming for purposes of determining the enterprise value of the Company. In light of Ultra’s view that debt was higher than it previously assumed, Ultra reduced the price per share of Company common stock so that the enterprise value remained constant over the two different debt levels. The representative also reported on recent discussions with representatives of Ultra’s financial advisors regarding the recent actions and efforts of Company management to negotiate an amendment of the Company’s credit facilities and the expected timing for entering into an amendment with the necessary lenders thereunder as well as the final due diligence work that Ultra desires to complete before the execution of a merger agreement. The representative of Wells Fargo Securities also reviewed the five recently received revised indications of interest from potential buyers of MDS. The purchase prices in such indications ranged from $45 million to $80 million for the sale of MDS on a cash-free, debt-free basis. A representative of Mayer Brown updated the process committee on the status of merger agreement negotiations that Mayer Brown had been having with Arnold & Porter. After discussion, the process committee instructed Wells Fargo Securities and Raymond James to engage with Ultra’s financial advisors to seek to obtain a per share price for Company common stock of at least $23.50. The process committee decided to extend the period of exclusivity with Ultra to July 6, 2017.

During the meeting, a representative of Wells Fargo Securities reported that, as instructed by the Company board, Wells Fargo Securities and Raymond James had contacted Guggenheim and RBC to seek to obtain a higher per share price for Company common stock, stating that the level of the Company’s indebtedness was the same as the amount Ultra had assumed when Ultra’s price per share of Company common stock was $23.50. Ultra’s financial advisors told Wells Fargo Securities and Raymond James they would discuss the matter with Ultra.

On June 30, 2017, Arnold & Porter sent to Mayer Brown a revised draft of the merger agreement.

Also on June 30, 2017, Guggenheim sent to Wells Fargo Securities a final “package deal” reflecting a revised final offer to acquire the Company for $23.50 per share of Company common stock, which was contingent on the Company accepting Ultra’s position on four major open points in the merger agreement: (i) Ultra would have no obligation to make any divestitures or agree to any restrictions on its business in connection with obtaining governmental approvals for the transaction and Ultra would have no obligation to litigate if a governmental authority filed suit challenging the transaction, (ii) the amount of the termination fees payable by the Company or Ultra in certain circumstances would each be $7.5 million, (iii) the Ultra board of directors would have no obligation to hold a meeting of the Ultra shareholders to vote on the approval of the transaction if the Ultra board of directors shall have changed its recommendation that Ultra shareholders should vote to approve the transaction and (iv) Ultra would not be required to hold the Ultra shareholders meeting by a date certain specified in the merger agreement.

Also on June 30, 2017, the Company entered into an amendment to its credit facility that, among other things, waived any event of default that may have occurred solely as a result of the Company’s failure to comply with its leverage covenants in the credit agreement for the test period ending on the last day of the Company’s fiscal quarter ending June 2017 and changed the trailing 4-quarter EBITDA requirements that the Company and its subsidiaries are to maintain to $22,500,000 for the fiscal quarter ending June 2017; $20,000,000 for the fiscal quarter ending September 2017; and $22,000,000 for the fiscal quarter ending December 2017.

A representative of Mayer Brown described for the Company board the terms in the merger agreement that the Company had been requesting from Ultra and the positions Ultra was taking in its package deal. After discussion, the Company board decided to accept the four positions in Ultra’s package deal, subject to clarifying Ultra’s draft of the merger agreement to provide that if the Ultra shareholders meeting is not held by a date prior to the outside date of the merger agreement, the Company would have the right to terminate the merger agreement and receive a termination fee from Ultra, and subject to Mayer Brown and Arnold & Porter negotiating the remaining outstanding terms of the merger agreement.

Later on July 1, 2017, a representative of Wells Fargo Securities reported to a representative of Guggenheim the conditions under which the Company board would accept Ultra’s package deal and the representative of Guggenheim confirmed those conditions were acceptable to Ultra.

From July 2, 2017 through July 6, 2017, Mayer Brown and Arnold & Porter finalized the terms of the merger agreement and disclosure schedules.

On July 5, 2017, the Company board held a telephonic meeting at which representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present to, among other things, consider the proposed merger with Ultra at a price of $23.50 per share of Company common stock. A representative of Mayer Brown reviewed with the members of the Company board their fiduciary duties under applicable law. Representatives of Wells Fargo Securities and Raymond James then joined the meeting and, with Mr. Hartnett, reviewed the developments in the marketing process since the last meeting of the Company board on July 1, 2017 with respect to the proposed transaction with Ultra and the solicitation of indications of interest for MDS. At the request of the Company board, representatives of Wells Fargo Securities and Raymond James then reviewed with the Company board their respective preliminary financial analyses with respect to the Company and the proposed merger. Mayer Brown provided the Company board with both a written and an oral summary of the key terms of the merger agreement, noting any items in the merger agreement that remained to be resolved. A representative of Mayer Brown also described for the Company board the resolutions that the Company board would consider adopting at its next meeting. Following discussion and consideration of the proposed transaction with Ultra, the Company board unanimously determined to proceed with the merger, assuming satisfactory finalization of definitive transaction documentation.

On July 6, 2017, the Company board held a telephonic meeting at which representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present to, among other things, consider the proposed merger with Ultra. A representative of Mayer Brown reviewed with the Company board the resolution of the issues in the merger agreement that had been unresolved as of the time of the meeting of the Company board on July 5, 2017. At the request of the Company board, representatives of Wells Fargo Securities reviewed with the Company board Wells Fargo Securities’ financial analyses with respect to the Company and the proposed merger. Thereafter, at the request of the Company board, Wells Fargo Securities rendered its oral opinion to the Company board (which was subsequently confirmed in writing by delivery of Wells Fargo Securities’ written opinion dated July 6, 2017) to the effect that, as of July 6, 2017, and based upon and subject to certain assumptions, qualifications, limitations and other matters considered in connection with the preparation of the opinion, the merger consideration to be received by the holders of shares of the Company common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to such holders. At the request of the Company board, representatives of Raymond James confirmed the financial analysis they had presented to the Company board at its meeting on July 5, 2017. Thereafter, at the request of the Company board, Raymond James rendered its oral opinion to the Company board (which was subsequently confirmed in writing by delivery of Raymond James’ written opinion dated July 6, 2017) that based upon and subject to the factors, limitations and assumptions set forth therein, as of July 6, 2017, the merger consideration to be paid to the holders of shares of the Company common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. The Company board then unanimously (i) determined that the merger agreement and the transactions

58

contemplated by the merger agreement, including the merger, are fair to the Company shareholders and are in the best interests of the Company and the Company shareholders, (ii) authorized, declared advisable and approved the merger agreement and the transactions contemplated by the merger agreement, including the merger, (iii) directed that a proposal for the adoption of the merger agreement be submitted to the Company shareholders for consideration at the special meeting and (iv) resolved to recommend that the Company shareholders adopt the merger agreement.

Early in the morning of July 7, 2017, the Company, Ultra and Merger Sub executed the Ultra merger agreement and the Company issued a press release announcing entry into the Ultra merger agreement prior to the opening of trading on the NYSE that morning.

Developments Following Execution of Ultra Merger Agreement

On July 21, 2017, each of the Company and Ultra filed with the Department of Justice and the Federal Trade Commission a premerger notification and report form under the HSR Act with respect to the transaction contemplated by the Ultra merger agreement (which we refer to as the “HSR filings”). Under the HSR Act and the rules promulgated thereunder, the transaction contemplated by the Ultra merger agreement could not be consummated until the Company and Ultra had made the HSR filings and furnished the necessary information to the Department of Justice and the Federal Trade Commission and until a 30-day waiting period (or any extension of the waiting period) expired or was terminated.

On August 21, 2017, after discussions with the Department of Justice, Ultra withdrew its HSR filing and then re-filed it on August 23, 2017. As a result of the re-filing, a second 30-day waiting period under the HSR Act commenced on August 23, 2017.

On September 22, 2017, the Department of Justice delivered notices to each of Ultra and the Company pursuant to which the Department of Justice made a second request for information in connection with the Department of Justice’s review of the transaction contemplated by the Ultra merger agreement (which we refer to as the “second request”). As a result of the second request, the waiting period under the HSR Act was extended until 30 days after Ultra and the Company had substantially complied with the second request.

On October 5, 2017, the Company held a special meeting of the Company shareholders and the Company shareholders voted in favor of adopting the Ultra merger agreement.

On October 23, 2017, the Company, Ultra and the Department of Justice entered into a timing agreement pursuant to which, among other things, the Company and Ultra agreed not to consummate the transaction contemplated by the Ultra merger agreement until 90 days following the date on which both of them shall have certified compliance with the second request, unless the Department of Justice’s investigation shall have been closed sooner, subject to certain exceptions.

On March 5, 2018, the Company announced the termination by the Company and Ultra of the Ultra merger agreement as a result of the staff of the Department of Justice informing the parties that it intended to recommend that the Department of Justice block the transaction contemplated by the Ultra merger agreement. Under an agreement entered into by the parties to the Ultra merger agreement, the parties agreed to release each other from certain claims and liabilities arising out of or related to the Ultra merger agreement or the transactions contemplated thereby, including any termination fees. The Company’s announcement also stated that, as a result of the termination of the Ultra merger agreement, the Company would seek to re-engage with parties that previously expressed an interest in acquiring all or a part of the Company and that are in a position to expeditiously proceed to effect such a transaction.

Also on March 5, 2018, the Company announced that, during the Department of Justice’s review of the transaction contemplated by the Ultra merger agreement, the Navy expressed the view that instead of the

59

Company and Ultra proceeding with such transaction, each of the Company and Ultra should enhance its ability to independently develop, produce and sell sonobuoys and over time work toward the elimination of their use of the ERAPSCO JV for such activities.

In addition, on March 5, 2018, a representative of Party B contacted Mr. Hartnett by telephone and indicated that Party B was once again interested in exploring a potential acquisition of the Company. Mr. Hartnett told the representative of Party B that the Company’s financial advisors would be contacting parties that might be interested in an acquisition of a portion or all of the Company and that the Company’s financial advisors would contact Party B’s financial advisor to discuss Party B’s interest in a potential acquisition of the Company.

From March 5, 2018 through March 9, 2018, at the direction of the Company board, the Company’s financial advisors contacted representatives of parties that previously expressed an interest in an acquisition of a portion or all of the Company, including a representative of the financial advisor for Party B.

On March 6, 2018, a representative of Cerberus contacted a representative of Wells Fargo Securities by telephone expressing interest in a potential acquisition of the Company. The representative of Wells Fargo Securities told the representative of Cerberus that executing a transaction expeditiously was a priority for the Company and that he would convey to the Company board Cerberus’ interest in a potential acquisition of the Company.

On March 7, 2018, the Department of Justice delivered notices to each of Mayer Brown (we refer to the notice to Mayer Brown as the “DOJ notice”) and counsel for Ultra stating that the Department of Justice had opened an investigation into the ERAPSCO agreement as being in potential violation of Section 1 of the Sherman Act (which we refer to as the “DOJ investigation”). Such notices also requested that certain documents and electronic information be preserved by the Company, Ultra and their respective affiliates and counsel in connection with the DOJ investigation.

On March 9, 2018, a representative of Party B contacted Mr. Hartnett by telephone to reiterate that Party B was interested in exploring a potential acquisition of the Company.

On March 12, 2018, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, representatives of Wells Fargo Securities and Raymond James informed the Company board that, since the Company had issued its press release regarding the termination of the Ultra merger agreement on March 5, 2018, Wells Fargo Securities and Raymond James had discussions with 15 parties, including Cerberus and Party B and a U.S. based manufacturer of defense products (which we refer to as “Party H”), regarding a potential transaction involving the Company. Party H had signed a non-disclosure agreement as part of the marketing process prior to the signing of the Ultra merger agreement, but had withdrawn in the initial phase of the marketing process after submitting two prior indications of interest to acquire ECP. A representative of Wells Fargo Securities also noted that Party B had indicated that it would send an updated list of due diligence requests and that it would be prepared to submit a new indication of interest within two weeks after Party B receives responses to such requests. The Company board also discussed resuming the marketing process to identify parties interested in exploring an acquisition of a portion or all of the Company, the length of time such parties would need to complete their due diligence in connection with the renewed marketing process and the effect the renewed marketing process would have on the business and operations of the Company.

Later on March 12, 2018, Party B sent a letter to Wells Fargo Securities stating that Party B remained interested in potentially acquiring the Company and requested that the Company provide certain due diligence materials. In the letter, Party B indicated that it anticipated that it could submit a new indication of interest one to two weeks following its receipt of such information. Party B also stated in its letter that it would request exclusivity with the Company for a period of time that was not specified in the letter following submission of its indication of interest.

60

On March 13, 2018, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, the Company board and representatives of Wells Fargo Securities and Raymond James discussed the March 12, 2018 letter from Party B. Wells Fargo Securities and Raymond James also reviewed and discussed 13 potential acquirers, including Cerberus, Party B and Party H, that either had reached out to Wells Fargo Securities and Raymond James following the termination of the Ultra merger agreement to express an interest in a potential strategic transaction with the Company or may have an interest in such a transaction. The Company board and the representatives of Wells Fargo Securities and Raymond James also discussed the logistics and timing associated with the marketing process and the amount of due diligence new participants in the marketing process might require. The Company board noted that Party B had conducted a significant amount of due diligence in the initial process and thus could be in a position to sign a definitive agreement to acquire the Company more quickly than other potential bidders. The Company board authorized management to engage with Party B regarding a potential strategic transaction involving the Company and to negotiate and execute any supplements, amendments or modifications to Party B’s non-disclosure agreement with the Company as management deemed advisable. The Company board also discussed the option of pursuing a standalone business plan in the event that Party B was not able to move forward quickly with a potential transaction. Following such discussions, the Company board authorized the Company to resume the marketing process and authorized Wells Fargo Securities and Raymond James to contact the 13 potential buyers that Wells Fargo Securities and Raymond James had identified to the Company board. Of such 13 potential buyers, nine had received signed non-disclosure agreements and received the CIP and five had attended management presentations in the marketing process prior to the execution of the Ultra merger agreement.

On March 15, 2018, Party B and the Company entered into a standstill agreement which supplemented the non-disclosure agreement signed by Party B and the Company during the marketing process. The standstill agreement included standstill provisions which, for a period of eighteen months, prohibited Party B, without the prior written consent of the Company board, from acquiring any securities of the Company or participating in a proposal for the Company either publicly or privately or from asking the Company to amend or waive such standstill provisions (often referred to as a “don’t ask, don’t waive” provision), except that (i) all of the standstill restrictions would automatically terminate (other than Party B’s restriction from acquiring the Company’s securities) if the Company enters into a definitive agreement with respect to (or has recommended that Company shareholders accept or approve) a transaction involving the acquisition of all or a majority of the Company’s outstanding equity securities or all or substantially all of the Company’s assets and (ii) nothing in the standstill agreement or the non-disclosure agreement would prohibit Party B making to the Company board on a confidential basis one or more proposals for a strategic transaction involving the Company.

On March 23, 2018, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Mayer Brown were present. During the meeting, Mr. Hartnett updated the Company board on the Company’s preliminary discussions with Party B regarding a potential strategic transaction with the Company and, based on a conversation he had with a representative of Party B, on Party B’s meeting with the Navy. The Company board then discussed the feasibility of resuming the marketing process to identify a beneficial strategic transaction expeditiously and the timing and logistics associated therewith. The Company board reactivated the process committee comprised of Messrs. Molfenter, Bazaar, Swartwout and Hartnett to conduct the marketing process. The process committee would be assisted and advised by Wells Fargo Securities, Raymond James and Mayer Brown and would have the authority, among other things, to negotiate and execute non-disclosure, standstill and other preliminary agreements and any amendments or modifications to any such agreements. The Company board and representatives of Mayer Brown discussed engaging a consultant in connection with a potential stand-alone business plan and the Company board determined that, in light of the commencement of the marketing process, the Company board would wait to engage such a consultant until it had further clarity on the results of the marketing process.

61

On March 27, 2018, Cerberus and the Company entered into a non-disclosure agreement which included standstill provisions substantially similar to the ones contained in the standstill agreement entered into by Party B and the Company on March 15, 2018.

On March 29, 2018, Party B sent an indication of interest to Wells Fargo Securities to acquire the Company for $23.50 per share of Company common stock. In its letter, Party B stated that its indication of interest was subject to the completion of confirmatory due diligence to Party B’s satisfaction, including being provided opportunities to meet with the Navy and Ultra regarding Party B’s potential acquisition of the Company and the ERAPSCO JV. Party B also requested 21 days of exclusivity with the Company.

On April 2, 2018, the process committee held a telephonic meeting at which representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the marketing process with 15 parties with which Wells Fargo Securities and Raymond James had discussions, including the timing and logistics associated therewith. The representative of Wells Fargo Securities also updated the process committee on preliminary discussions with Party B’s financial advisor regarding Party B’s March 29, 2018 proposal. After discussion, the process committee directed Wells Fargo Securities to deliver a process letter to each of the potential buyers participating in the marketing process.

On April 4, 2018, as directed by the process committee, Wells Fargo Securities (i) sent to each of the potential buyers participating in the marketing process a process letter requesting indications of interest to acquire the Company to be submitted by April 18, 2018 and (ii) provided each of the participants in the marketing process that had executed non-disclosure agreements access to limited due diligence materials regarding the Company and its businesses via an online virtual data room.

On April 6, 2018, the process committee held a telephonic meeting at which representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including that, to date, five strategic buyers and six financial buyers had executed non-disclosure agreements, amendments to existing non-disclosure agreements or standstill agreements each of which included standstill provisions substantially similar to the ones contained in the standstill agreement entered into by Party B and the Company on March 15, 2018. Such representative of Wells Fargo Securities also updated the process committee on discussions between Wells Fargo Securities and Party B’s financial advisor. Mr. Hartnett informed the process committee that a meeting among Mr. Hartnett, representatives of Party B and Ultra had been scheduled for April 13, 2018 at Ultra’s headquarters. The process committee then discussed Party B’s request for exclusivity and determined that such exclusivity would only be granted after Party B had completed all of its substantive due diligence.

Also on April 6, 2018, a representative of Party G that was employed by a significant shareholder of Party G contacted a representative of Wells Fargo Securities by telephone to express Party G’s interest in a potential acquisition of the Company.

From April 6, 2018 through April 13, 2018, representatives of Wells Fargo Securities and representatives of Party G (including employees of Party G’s significant shareholder) had several discussions regarding the marketing process and Party G’s interest in acquiring the Company.

On April 9, 2018, a representative of a potential strategic buyer contacted Mr. Hartnett by email to indicate that the strategic buyer may be interested in exploring a potential acquisition of the Company. Later that day, at the request of the Company, Wells Fargo Securities confirmed that the Company was interested in having such strategic buyer participate in the marketing process.

On April 11, 2018, Wells Fargo Securities sent such strategic buyer the form of non-disclosure agreement. After a series of discussions between Wells Fargo Securities and such strategic buyer, a representative of the strategic

62

buyer informed representatives of Wells Fargo Securities by email on April 16, 2018 that such strategic buyer would not be participating in the marketing process.

On April 11, 2018, as directed by the process committee, Wells Fargo Securities sent to Party B a form of merger agreement, which had been prepared by Mayer Brown and approved by the process committee. The draft was substantially similar to the Ultra merger agreement except that, among other things, (i) the provisions specific to Ultra (such as those relating to Ultra’s shareholder vote) were deleted, (ii) the parent termination fee would be payable if the merger agreement was terminated due to a failure to obtain requisite regulatory approvals and (iii) the amount of the parent termination fee would be two times the amount of the termination fee.

Between April 13, 2018 and April 17, 2018, members of Company management held telephonic meetings with several of the participants in the marketing process, including Cerberus and Party H, to discuss, among other things, the ERAPSCO JV and such participant’s interest in acquiring the Company and due diligence of the Company.

On April 13, 2018, Mr. Hartnett and representatives of Party B and Ultra held a meeting at Ultra’s corporate headquarters to discuss the ERAPSCO JV and their expectations for the future conduct of the ERAPSCO JV in the event Party B were to acquire the Company.

Also on April 13, 2018, a representative of Wells Fargo Securities sent the form non-disclosure agreement to a representative of Party G and encouraged Party G to proceed expeditiously as the marketing process had already commenced and other participants in the marketing process had already begun their due diligence review of the Company.

On April 16, 2018, the process committee held a telephonic meeting at which representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, Mr. Hartnett updated the process committee on the meeting with Party B and Ultra and informed the process committee that a meeting between Party B and the Navy had been scheduled for April 18, 2018. A representative of Wells Fargo Securities updated the process committee on the status of the marketing process and indicated that it was still anticipating that the potential buyers, including Party B, Party H and Cerberus, would deliver their indications of interest on or around April 18, 2018.

On April 17, 2018, Party G sent a mark-up of the form of non-disclosure agreement to Wells Fargo Securities.

On April 18, 2018, Mr. Hartnett and representatives of Party B held a meeting with the Navy regarding Party B’s potential acquisition of the Company.

Also on April 18, 2018, at the instruction of the Company, a representative of Wells Fargo Securities indicated to Party G that, given the role that the significant shareholder of Party G was playing in Party G’s consideration of a potential acquisition of the Company, the Company would require that such significant shareholder be a party to the non-disclosure agreement in order for Party G to participate in the marketing process.

Later on April 18, 2018, the Company determined not to allow Party G to participate in the marketing process in light of the fact that the participants in the marketing process were further along in their due diligence of the Company, that allowing Party G to catch up with other bidders could result in a delay of the marketing process and that executing a transaction expeditiously was a priority for the Company.

On April 18, 2018 and April 19, 2018, Wells Fargo Securities, on behalf of the Company, received indications of interest from four strategic buyers, including Party B (which updated its current indication of interest) and Party H, and one financial buyer, which was Cerberus. The initial indications of interest reflected indicative prices ranging from $21.00 to $23.50 per share of Company common stock. Cerberus’ indication of interest contained a proposal to acquire the entire Company for $23.50 per share of Company common stock and stated that (i) its

63

proposal was contingent on satisfactory completion of due diligence which it expected to complete within 30 days and (ii) it intended to acquire both ECP and MDS. Party B did not submit a new indication of interest letter, but Party B submitted a mark-up of the draft merger agreement sent to Party B on April 11, 2018 in which Party B, among other things, deleted the provisions providing that the parent termination fee would be payable if the merger agreement was terminated due to a failure to obtain requisite regulatory approvals. A representative of Party B also told representatives of Wells Fargo Securities and Raymond James that based on updated share count information in the Company’s dataroom, Party B’s price per share of Company common stock was $22.25. Party H submitted a proposal to acquire the entire Company at a price of $23.00 per share of Company common stock and stated that it expected that its due diligence would be completed and a merger agreement with the Company could be executed within 45 to 60 days.

Also on April 19, 2018, Wells Fargo Securities, on behalf of the Company, received an unsolicited indication of interest from Party G which contained a proposal to acquire the entire Company for $24.00 per share of Company common stock, which proposal was based solely on publicly available information.

On April 20, 2018, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities provided a summary of the financial terms of the six proposals received on April 18, 2018 and April 19, 2018, with indicative prices ranging from $21.00 to $24.00 per share of Company common stock, and a description of the extent of due diligence conducted by each potential buyer. As part of the summary, the representative of Wells Fargo Securities noted that Party G’s indicated price of $24.00 per share of Company common stock was based on publicly available information and that, taking into account additional information in the Company’s dataroom, which information was made available to the participants in the marketing process, Party G’s indicated price was equivalent to $22.48 per share of Company common stock. The Company board, with the assistance of representatives of Wells Fargo Securities and Mayer Brown, discussed the circumstances involving Party G and affirmed the Company’s decision to exclude Party G from the marketing process. Representatives of Mayer Brown described the changes made by Party B in its mark-up of the draft merger agreement. Mr. Hartnett also provided the Company board an update on his meeting with Party B and the Navy. Following such discussions, the Company board instructed Wells Fargo Securities to indicate to Party B that granting Party B exclusivity would be based on the following conditions: (i) Party B must confirm a price of $23.50 per share of Company common stock, (ii) Party B must agree that the merger agreement would include provisions providing that the parent termination fee would be payable if the merger agreement was terminated due to a failure to obtain requisite regulatory approvals and (iii) a discussion between Party B’s counsel and Mayer Brown must be held to discuss regulatory due diligence matters relating to Party B and the results of such discussion must not indicate any significant regulatory risk associated with a transaction for the Company to be acquired by Party B. The Company board also authorized Messrs. Swartwout and Hartnett to negotiate the terms of and execute an exclusivity agreement with Party B for an exclusivity period not to exceed 21 days, subject to satisfaction of the foregoing conditions.

On April 23, 2018, representatives of Party B’s financial advisor informed representatives of Wells Fargo Securities and Raymond James that Party B had determined that, after consideration of the due diligence information that had been provided to date, including with respect to the Company’s financial condition, the uncertainty of the future of the ERAPSCO JV and the anticipated difficulty in executing a post-acquisition divestiture of MDS, Party B’s board of directors decided that Party B would not be moving forward with a potential acquisition of the Company and would be withdrawing from the marketing process.

On April 25, 2018, the Company board held a meeting at which representatives of the Company’s senior management and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the Company board on the status of the marketing process. Wells Fargo Securities also discussed with the Company board Party B’s withdrawal from the marketing process and reviewed the financial terms of the proposals received from the five other potential buyers on April 18, 2018 and April 19, 2018. The representatives of Wells Fargo Securities and Raymond James

64

indicated that Party G’s proposal was less credible than those of other bidders because such bidders had access to additional due diligence materials of the Company and Party G had relied exclusively on publicly available information. Following this review, the Company board noted that Cerberus’ and Party H’s proposals reflected the highest prices proposed by all potential buyers in the marketing process and that Cerberus and Party H had been more active in their due diligence than the other potential buyers. The Company board then discussed information Wells Fargo Securities had provided to the Company board in advance of the meeting regarding business relationships between Wells Fargo Securities and Cerberus and Party H. A representative of Raymond James informed the Company board that Raymond James would provide the Company board disclosures regarding its relationships with Cerberus and Party H at a later point in time. After discussion, the Company board determined (i) to continue the marketing process, (ii) to allow Cerberus and Party H into the next stage of the marketing process and (iii) to allow Party H to contact a financial acquirer that owned and operated businesses in the contract manufacturing industry (which we refer to as “Party I”), with which Ultra had engaged in discussions to sell MDS prior to the termination of the Ultra merger agreement, as Party H had indicated that it did not intend to hold MDS and that Party H needed certainty with respect to how it would divest MDS if it were to acquire the Company.

On April 26, 2018, as directed by the Company board, Wells Fargo Securities sent to Cerberus and Party H a form of merger agreement, which had been prepared by Mayer Brown and approved by the process committee, for their review and comment to be included in their proposals.

On April 30, 2018, Wells Fargo Securities sent to Cerberus and Party H a process letter requesting final proposals to acquire the entire Company to be submitted by May 16, 2018.

On May 2, 2018, representatives of Company management held a due diligence call with representatives of Cerberus, Lowenstein Sandler LLP, transaction counsel to Cerberus (which we refer to as “Lowenstein Sandler”), and Blank Rome LLP, government contracts counsel to Cerberus (which we refer to as “Blank Rome”), to discuss matters relating to the ERAPSCO JV, including the DOJ investigation. Representatives of Wells Fargo Securities were also present on this call.

On May 3, 2018, at the Company’s corporate headquarters, Mr. Hartnett and other members of Company management gave a management presentation to Cerberus regarding the Company, its business segments and operations and its historical and projected financial performance.

On May 4, 2018, the process committee held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, Mr. Hartnett and a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including discussions with representatives of Cerberus and Party H, and Party H’s intent to engage Party I and possibly other third parties in connection with a potential sale of MDS.

On May 7, 2018 and May 8, 2018, at the Company’s facility in DeLeon Springs, Florida, members of Company management met with Cerberus for a site visit and to discuss the ERAPSCO JV, the Company’s business and historical operations and the Company’s projected financial performance. Mr. Hartnett attended such meeting by telephone.

On May 9, 2018, representatives of Cerberus, Mayer Brown, Lowenstein Sandler and Blank Rome had a conference call to further discuss the DOJ investigation.

On May 10, 2018, at the Company’s facility in DeLeon Springs, Florida, members of Company management gave a management presentation to Party H regarding the Company, its business segments and operations and its historical and projected financial performance and gave a tour of such facility. Mr. Hartnett attended such management presentation by telephone.

65

On May 14, 2018, the process committee held a telephonic meeting at which representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Wells Fargo Securities updated the process committee on the status of the marketing process, including progress made by Cerberus and Party H in their respective due diligence of the Company.

On May 16, 2018, Wells Fargo Securities received updated indications of interest from Cerberus and Party H. In addition, Party H’s indication of interest included its proposed mark-up of the form of merger agreement. Cerberus’ indication of interest contained a proposal to acquire the entire Company for $22.00 per share of Company common stock, reaffirmed its intention to acquire both ECP and MDS and requested 21 days of exclusivity. Party H’s indication of interest contained a proposal to acquire the entire Company for $23.50 per share of Company common stock and requested 30 days of exclusivity, but did not include any proposed plan with respect to a sale of MDS.

On May 17, 2018, Wells Fargo Securities received Cerberus’ proposed mark-up of the form of merger agreement.

On May 18, 2018, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, a representative of Mayer Brown described for the members of the Company board the business relationships with Cerberus and Party H that were disclosed by each of Wells Fargo Securities and Raymond James. After consideration of such disclosures, the Company board determined that such relationships would not be likely to impair the ability of Wells Fargo Securities and Raymond James to provide objective advice and concluded that it was appropriate for the Company board to continue to receive advice from such financial advisors. Following such discussion, a representative of Wells Fargo Securities provided a summary of the financial terms of Cerberus’ and Party H’s proposals received on May 16, 2018. The representative of Wells Fargo Securities also discussed the extent of due diligence performed by each of Cerberus and Party H and noted that Cerberus had performed substantially more due diligence than Party H to date. A representative of Mayer Brown then described the changes made by Cerberus and Party H in their respective mark-ups of the form of merger agreement and noted that Cerberus’ mark-up was far more extensive than that of Party H. After further discussion, the Company board determined that it was not the appropriate time to enter into exclusivity with either Cerberus or Party H. The Company board then instructed Wells Fargo Securities to (i) inform Cerberus and Party H that the Company would not provide exclusivity and press them to commit to a timeframe to executing a merger agreement with the Company, (ii) make a counterproposal to Cerberus to increase its price from $22.00 to $23.50 per share of Company common stock and (iii) press Party H to increase the pace of its due diligence and commit to a plan with respect to its potential sale of MDS. The Company board also instructed Mayer Brown to engage with counsel for Cerberus to negotiate the terms of the merger agreement.

Later on May 18, 2018, representatives of Wells Fargo Securities contacted representatives of Cerberus by telephone to relay the Company board’s counterproposal that Cerberus increase its price from $22.00 to $23.50 per share of Company common stock, which the representatives of Cerberus and Wells Fargo Securities discussed and the representatives of Cerberus said they would consider further. The representatives of Wells Fargo Securities also informed Cerberus that the Company board would not grant Cerberus exclusivity at such time and asked Cerberus to confirm whether it was willing to proceed on that basis, and the representatives of Cerberus indicated that they would consider proceeding on that basis.

Also on May 18, 2018, representatives of Wells Fargo Securities and Raymond James contacted representatives of Party H and Party H’s financial advisor and discussed the status of Party H’s due diligence and Party H’s plans with respect to a potential sale of MDS. In the course of their discussion, the representatives of Party H indicated that Party H was prepared to proceed expeditiously with their due diligence and execute a merger agreement within 30 days provided the results of due diligence are satisfactory. The representatives of Party H also indicated that Party H’s entering into a merger agreement to acquire the Company would not be contingent on finalizing the terms of a sale of MDS. The representatives of Wells Fargo Securities and Raymond James also

66

informed Party H that the Company board would not grant Party H exclusivity at such time and asked Party H to confirm whether it was willing to proceed on that basis, and the representatives of Party H indicated that they would consider proceeding on that basis.

On May 19, 2018, representatives of Mayer Brown had a conference call with representatives of Lowenstein Sandler to negotiate terms of the merger agreement. During the call, Mayer Brown and Lowenstein Sandler engaged in discussions and negotiations regarding, among other things, (i) the scope of each party’s representations and warranties in the merger agreement, including the Company’s representations and warranties with respect to government contracting matters and the ERAPSCO JV, (ii) financing matters, (iii) the circumstances in which a termination fee would become payable by the Company to Parent and the size of such fee and (iv) the circumstances in which a termination fee would become payable by Parent to the Company and the size of such fee.

On May 22, 2018, representatives of Cerberus contacted representatives of Wells Fargo Securities by telephone to inform them that Cerberus would not increase its price of $22.00 per share of Company common stock, but it was willing to proceed without being provided exclusivity.

On October 22, 2018, Lowenstein Sandler sent mark-ups of the merger agreement, the equity commitment letter and the limited guarantee to Mayer Brown.

On October 24, 2018, the Company board held a telephonic meeting at which Mr. McCormack and representatives of Wells Fargo Securities, Raymond James and Mayer Brown were present. During the meeting, the Company board, with the assistance of Mr. McCormack and representatives of Wells Fargo Securities and Raymond James, discussed a revision to the projections prepared by Company management and shared with Cerberus through the online virtual data room, which revision would reflect financial information relating to additional potential sonobuoy sales in connection the recent increase in the federal budget for sonobuoy purchases and potential Q-125A sonobuoy sales, in light of the Navy’s recent corrective action with respect to the range exclusion. The revision to the financial forecasts would result in an increase to the Company’s projected revenues, income and other related financial metrics. A representative of Wells Fargo Securities noted that, although not reflected in the projections available to Cerberus in the online virtual data room, the information that underlies the revision to the projections had already been provided to Cerberus prior to its October 5, 2018 proposal and that Cerberus was nearly complete with its financial due diligence. The Company board also discussed requesting that Cerberus increase its price in light of the revision to the projections and the potential delay associated with such a request. Representatives of Mayer Brown also discussed the status of the transaction documents, including the merger agreement, the limited guarantee and the equity commitment letter. After discussion, the Company board authorized Company management to make the revised projections available to Cerberus and determined that it would consider whether to request a higher price from Cerberus after such revised projections had been provided to Cerberus.

On October 29, 2018, representatives of Cerberus, Lowenstein Sandler and Mayer Brown had a conference call to further discuss the Company’s views as to the ERAPSCO transfer provisions and the Ultra consent.

After discussion, the Company board determined that it would permit Cerberus to seek the Ultra consent but would not permit Cerberus to seek any amendment to the ERAPSCO agreement. The Company board, with the assistance of its financial advisors, also considered whether to seek a price increase from Cerberus and determined that, in light of the recent revised projections prepared by Company management, Cerberus’ previous awareness of the information that was reflected in the recent revised projections, the Company’s recent financial performance, and the risks of a potential delay in signing the merger agreement, it would not seek such an increase from Cerberus.

A representative of Mayer Brown then described for the members of the Company board the business relationships with Cerberus that were disclosed by each of Wells Fargo Securities and Raymond James to the Company board in advance of the meeting.

The Company board recommends that you vote “FOR” the merger proposal.

Reasons for the Merger

Following the termination of the Ultra merger agreement on March 4, 2018, the Company board held 25 meetings and the process committee held 7 meetings at which the potential acquisition of the Company was discussed. The Company’s outside legal advisor, Mayer Brown, participated in portions of all of these meetings, and the Company’s financial advisors, Wells Fargo Securities and Raymond James, participated in portions of certain of these meetings.

At a meeting held on December 11, 2018, the Company board unanimously (i) determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to the Company shareholders and are in the best interests of the Company and the Company shareholders, (ii) declared advisable and approved the merger agreement and the execution, delivery and performance of the merger

81

agreement and the transactions contemplated by the merger agreement, including the merger, (iii) directed that a proposal for the adoption of the merger agreement be submitted to the Company shareholders for consideration at the special meeting and (iv) recommended that the Company shareholders adopt the merger agreement.

In reaching its decision to unanimously approve and recommend the adoption of the merger agreement and to recommend that the Company shareholders approve the merger proposal, the Company board consulted with Company management, as well as its legal and financial advisors, and considered numerous factors, including, but not limited to, the following material factors (not in any relative order of importance):

85

The foregoing discussion of the information and factors considered by the Company board is not intended to be exhaustive, but includes the material factors considered by the Company board. In view of the variety of factors considered in connection with its evaluation of the merger, the Company board did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination and recommendation. In addition, individual directors may have given different weights to different factors. The Company board did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determination.

The Company board based its recommendation on the totality of the information presented.

Portions of this explanation of the reasons for the merger and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the section entitled “Cautionary Statement Regarding Forward-Looking Statements.”

Unaudited Prospective Financial Information

The Company does not as a matter of course make public projections as to future performance, revenues, earnings or other financial results due to, among other reasons, the inherent uncertainty and unpredictability of the underlying assumptions and estimates. However, the Company is including in this proxy statement a summary of certain unaudited prospective financial information that was provided to the Company board for use in connection with its evaluation of the proposed merger and to the Company financial advisors, who were authorized to rely upon such projections, including for Wells Fargo Securities’ and Raymond James’ use in providing financial advice to the Company board. The inclusion of this information should not be regarded as an indication that any of the Company, Cerberus, Parent, Merger Sub, Wells Fargo Securities, Raymond James, their respective representatives or any other recipient of this information considered, or now considers, it necessarily to be predictive of actual future results (which may be significantly more or less favorable), or that it should be construed as financial guidance, and it should not be relied on as such. None of the Company, Cerberus, Parent, Merger Sub, Wells Fargo Securities, Raymond James or any other person assumes responsibility if future results are materially different from those discussed in this proxy statement. In addition, analyses relating to the value of the Company’s business do not purport to be appraisals or reflect the prices at which the Company’s business may actually be sold. Company management directed Wells Fargo Securities and Raymond James to use the unaudited prospective financial information with respect to the Company that was provided by Company management in connection with the preparation of the financial analyses Wells

86

Fargo Securities and Raymond James reviewed and discussed with the Company board at its meeting on December 11, 2018 and the preparation of Wells Fargo Securities’ and Raymond James’ opinions to the Company board rendered at that meeting.

While presented with numeric specificity, the unaudited prospective financial information reflects numerous estimates and assumptions made with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to the Company’s business, all of which are difficult to predict and many of which are beyond the Company’s control. The unaudited prospective financial information reflects both assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. The Company can give no assurance that the unaudited prospective financial information and the underlying estimates and assumptions will be realized. In addition, since the unaudited prospective financial information covers multiple years, such information by its nature becomes less predictive with each successive year. Furthermore, the unaudited prospective financial information should not be construed as commentary by Company management as to how Company management expects the Company’s actual results to compare to Wall Street research analysts’ estimates, as to which the Company expresses no view.

Actual results may differ materially from those set forth below, and important factors that may affect actual results and cause the unaudited prospective financial information to be inaccurate include, but are not limited to, risks and uncertainties relating to the Company’s business, industry performance, general business and economic conditions, customer requirements, competition and adverse changes in applicable laws, regulations or rules. For other factors that could cause actual results to differ, please see the section entitled “Cautionary Statement Concerning Forward-Looking Statements” in this proxy statement and the sections entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 2018 Annual Report, its Quarterly Report on Form 10-Q for the quarter ended September 30, 2018 and the other reports filed by the Company with the SEC.

The unaudited prospective financial information does not take into account any circumstances or events occurring after the date it was prepared. The Company can give no assurance that, had the unaudited prospective financial information been prepared as of the date of this proxy statement, similar estimates and assumptions would be used. The Company does not intend to, and disclaims any obligation to, make publicly available any update or other revision to the unaudited prospective financial information to reflect circumstances existing since its preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the assumptions underlying the unaudited prospective financial information are shown to be in error, or to reflect changes in general economic or industry conditions. The unaudited prospective financial information does not take into account the possible financial and other effects on the Company of the merger and does not attempt to predict or suggest future results of the combined company. The unaudited prospective financial information does not give effect to the merger, including the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the merger, the potential synergies that may be achieved by the combined company as a result of the merger or the effect of any business or strategic decisions or actions which would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger. Further, the unaudited prospective financial information does not take into account the effect on the Company of any possible failure of the merger to occur. None of the Company, Wells Fargo Securities, Raymond James or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any Company shareholder or other person regarding the Company’s ultimate performance compared to the information contained in the unaudited prospective financial information or that the forecasted results will be achieved. The summary of the unaudited prospective financial information included below is being provided solely because it was made available to the Company board, Cerberus, Parent, and Wells Fargo Securities and Raymond James, financial advisors to the Company, and not to influence your decision as to whether to vote for the merger proposal.

87

The Company board, Cerberus, Parent, Wells Fargo Securities and Raymond James were provided with unaudited prospective financial information with respect to the Company prepared by Company management for the fiscal years 2019 through 2023, and calendar years 2018 (“CY 2018E”) and 2019 (“CY 2019P”). The following table summarizes selected unaudited prospective financial data for the fiscal years 2019 through 2023, and CY 2018 and CY 2019, prepared based on historical data available to the Company as of September 30, 2018, for each of MDS, ECP, corporate, and on a consolidated basis.

88

The unaudited prospective financial information was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with accounting principles generally accepted in the United States of America, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither the Company’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the unaudited prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability. The independent registered public accountant reports incorporated by reference into this proxy statement relate to the Company’s historical financial information. They do not extend to the unaudited prospective financial information and should not be read to do so.

In light of the foregoing, and considering that the special meeting will be held after the unaudited prospective financial information was prepared, as well as the uncertainties inherent in any forecasted information, Company shareholders are cautioned not to place unwarranted reliance on such information, and the Company urges all Company shareholders to review the Company’s most recent SEC filings for a description of the Company’s reported financial results. See “Where You Can Find More Information.”

Opinion of Raymond James & Associates, Inc.

The Company retained Raymond James as financial advisor on November 18, 2016. Pursuant to that engagement, the Company board requested that Raymond James evaluate the fairness, from a financial point of view, to the Company’s shareholders of the merger consideration to be received by such shareholders pursuant to the merger agreement.

At the December 11, 2018 meeting of the Company’s board, representatives of Raymond James rendered its oral opinion to the Company board (which was subsequently confirmed in writing by delivery of Raymond James’ written opinion dated the same date), that, as of the date of such opinion, the merger consideration to be received by Company shareholders in the merger pursuant to the merger agreement was fair, from a financial point of view, to Company shareholders based upon market, economic, financial and other circumstances and conditions existing and disclosed to Raymond James as of December 10, 2018 and based upon and subject to the qualifications, assumptions and other matters considered in connection with the preparation of its opinion.

The full text of the written opinion of Raymond James is attached as Annex B-1 to this proxy statement. The summary of the opinion of Raymond James set forth in this proxy statement is qualified in its entirety by reference to the full text of such written opinion. Company shareholders are urged to read this opinion in its entirety.

89

Raymond James provided its opinion for the information of the Company board (solely in its capacity as such) in connection with, and for purposes of, its consideration of the merger and its opinion only addresses whether the merger consideration to be received by Company shareholders in the merger pursuant to the merger agreement was fair, from a financial point of view, to such shareholders. The opinion of Raymond James does not address any other term or aspect of the merger agreement or the merger contemplated thereby. The Raymond James opinion does not constitute a recommendation to the Company board or to any Company shareholder as to how the Company board, such Company shareholder or any other person should vote or otherwise act with respect to the merger or any other matter.

In connection with its review of the proposed merger and the preparation of its opinion, Raymond James, among other things:

With the Company’s consent, Raymond James assumed and relied upon the accuracy and completeness of all information supplied by or on behalf of the Company, or otherwise reviewed by or discussed with Raymond James, and Raymond James did not undertake any duty or responsibility to, nor did Raymond James, independently verify any of such information. Raymond James did not make or obtain an independent appraisal of the assets or liabilities (contingent or otherwise) of the Company. With respect to the Projections and any other information and data provided by the Company to or otherwise reviewed by or discussed between Raymond James and the Company, Raymond James, with the Company’s consent, assumed that the Projections

90

and such other information and data were reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of management of the Company and Raymond James relied upon the Company to advise Raymond James promptly if any information previously provided by the Company became inaccurate or was required to be updated during the period of Raymond James’s review. Raymond James expressed no opinion with respect to the Projections or the assumptions on which they were based. Raymond James assumed that the final form of the merger agreement would be substantially similar to the draft agreement reviewed by Raymond James, and that the merger would be consummated in accordance with the terms of the merger agreement without waiver or amendment of any conditions thereto. Furthermore, Raymond James assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the merger agreement were true and correct and that each party will perform all of the covenants and agreements required to be performed by it under the merger agreement without being waived. Raymond James also relied upon and assumed, without independent verification, that (i) the merger would be consummated in a manner that complies in all respects with all applicable international, federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the merger would be obtained and that no delay, limitations, restrictions or conditions would be imposed or amendments, modifications or waivers made that would have an effect on the merger or the Company that would be material to its analysis or opinion.

Raymond James expressed no opinion as to the underlying business decision to effect the merger, the structure or tax consequences of the merger, or the availability or advisability of any alternatives to the merger. The Raymond James opinion is limited to the fairness, from a financial point of view, of the merger consideration to be received by the Company shareholders. Raymond James expressed no opinion with respect to any other reasons (legal, business, or otherwise) that may support the decision of the Company board to approve or consummate the merger. Furthermore, no opinion, counsel or interpretation was intended by Raymond James on matters that require legal, accounting or tax advice. Raymond James assumed that such opinions, counsel or interpretations had been or would be obtained from appropriate professional sources. Furthermore, Raymond James relied, with the consent of the Company, on the fact that the Company was assisted by legal, accounting and tax advisors, and, with the consent of the Company relied upon and assumed the accuracy and completeness of the assessments by the Company and its advisors, as to all legal, accounting and tax matters with respect to the Company and the merger.

In formulating its opinion, Raymond James considered only the merger consideration to be received by the Company shareholders, and Raymond James did not consider, and its opinion did not address, the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company, or such class of persons, in connection with the merger whether relative to the merger consideration or otherwise. Raymond James was not requested to opine as to, and its opinion did not express an opinion as to or otherwise address, among other things: (1) the fairness of the merger to the holders of any class of securities, creditors or other constituencies of the Company, or to any other party, except and only to the extent expressly set forth in the last sentence of its opinion or (2) the fairness of the merger to any one class or group of the Company’s or any other party’s security holders or other constituents vis-à-vis any other class or group of the Company’s or such other party’s security holders or other constituents (including, without limitation, the allocation of any consideration to be received in the merger amongst or within such classes or groups of security holders or other constituents). Raymond James expressed no opinion as to the impact of the merger on the solvency or viability of the Company or the ability of the Company to pay its obligations when they come due.

Material Financial Analyses

The following summarizes the material financial analyses reviewed by Raymond James with the Company board at its meeting on December 11, 2018, which material was considered by Raymond James in rendering its opinion. No company or transaction used in the analyses described below is identical or directly comparable to the Company or the contemplated merger.

91

Selected Companies Analysis. Raymond James analyzed the relative valuation multiples of fifteen publicly-traded companies, consisting of eight Electronic Manufacturing Services (“EMS”) companies and seven Defense Electronics (“DE”) companies, that it deemed relevant, including:

Electronic Manufacturing Services:

Defense Electronics:

The two independent data sets were compiled and applied to each operating segment of the Company. The EMS data set of companies was compiled for the MDS business, while the DE data set of companies was compiled for the ECP business. The EBITDA multiples derived from each data set were weighted based on each segment’s respective percentage contribution to its corresponding period’s Management EBITDA and applied to the total Management EBITDA for the respective period to reach a weighted conclusion. For the calendar year ending December 31, 2018, 75.5% was weighted to the ECP business and 24.5% was weighted to the MDS business. For the calendar year ending December 31, 2019, 69.5% was weighted to the ECP business and 30.5% was weighted to the MDS business. Given Raymond James’ understanding of the Company’s business and the relative significance of the two operating businesses, in Raymond James’ professional judgment, weighting the respective businesses in this manner was an appropriate and reasonable way to value the enterprise. Management EBITDA is a term utilized by the Company management and is defined as earnings before interest, taxes, depreciation, and amortization plus adjustments for facilities consolidation, earnouts, goodwill, and other one-time, and non-recurring items provided by the Company management.

Raymond James calculated various financial multiples for each company, including enterprise value (market value plus debt, plus preferred stock, plus minority interests, less cash and equivalents) compared to EBITDA,

92

using publicly available consensus research EBITDA estimates for the selected companies for calendar years ending December 31, 2018 and 2019, referred to as CY2018E and CY2019P. The estimates published by research analysts were not prepared in connection with the merger or at the request of Raymond James and may or may not prove to be accurate. Raymond James reviewed the mean, median, minimum and maximum relative valuation multiples of the selected public companies and compared them to corresponding valuation multiples for the Company implied by the merger consideration. The results of the selected public companies analysis are summarized below:

Furthermore, Raymond James applied the mean, median, minimum and maximum relative valuation multiples for each of the metrics to the Company’s actual and projected financial results and determined the implied equity price per share of Company common stock and then compared those implied equity values per share to the merger consideration of $18.50 per share. The results of this are summarized below:

93

Selected Transaction Analysis. Raymond James analyzed publicly available information relating to selected acquisitions of companies in the EMS and DE sectors, with transaction enterprise values below one billion dollars that closed during the last eight years and prepared a summary of the relative valuation multiples paid in these transactions. The selected transactions used in the analysis were:

Electronic Manufacturing Services:

94

Defense Electronics:

The two independent data sets were compiled for each operating segment of the Company. The EMS data set of transactions was compiled for the MDS business, while the DE data set of transactions was compiled for the ECP business. The EBITDA multiples derived from each data set were weighted based on each segment’s respective percentage contribution to the trailing twelve months (“TTM”) Management EBITDA (MDS TTM as of September 30, 2018 at 21.4% and ECP TTM as of September 30, 2018 at 78.6%) and applied to the total TTM Management EBITDA to reach a weighted conclusion. Given Raymond James’ understanding of the Company’s business and the relative significance of the two operating businesses, in Raymond James’ professional

95

judgment, weighting the respective businesses in this manner was an appropriate and reasonable way to value the enterprise.

Raymond James examined valuation multiples of transaction enterprise value compared to the target companies’ EBITDA, in each case for twelve months ended prior to closing of the transaction, where such information was publicly available. Raymond James reviewed the mean, median, minimum and maximum relative valuation multiples of the selected transactions and compared them to corresponding valuation multiples for the Company implied by the merger consideration. Furthermore, Raymond James applied the mean, median, minimum and maximum relative valuation multiples to the Company’s actual TTM EBITDA to determine the implied equity price per share and then compared those implied equity values per share to the merger consideration of $18.50 per share. The results of the selected transactions analysis are summarized below:

Discounted Cash Flow Analysis. Raymond James analyzed the discounted present value of the Company’s projected free cash flows beginning September 30, 2018 through the end of fiscal year 2019 and continuing through the end of fiscal year 2023 on a standalone basis. Raymond James calculated unlevered free cash flows, defined as earnings before interest, after taxes, plus depreciation, plus amortization, less capital expenditures, less investment in working capital.

The discounted cash flow analysis was based on the Projections. Consistent with the periods included in the Projections, Raymond James used fiscal year 2023 as the final year for the analysis and utilized two methodologies for comparison purposes to calculate a terminal value: (i) applied multiples ranging from 9.0x to 11.0x, selected by Raymond James upon the application of its professional judgment and expertise, to fiscal year 2023 EBITDA in order to derive a range of terminal values for the Company in 2023 and (ii) applied perpetual growth rates ranging from 2.0% to 4.0%, selected by Raymond James upon the application of its professional judgment and expertise, to fiscal year 2023 unlevered free cash flow in order to derive a range of terminal values for the Company in 2023.

96

The projected unlevered free cash flows and terminal values were discounted using rates ranging from 11.0% to 13.0%, which range was selected, upon the application of Raymond James’s professional judgment and expertise, to reflect the weighted average after-tax cost of debt and equity capital associated with executing the Company’s business plan. This range was selected based on Raymond James’ experience and judgment and an estimate of the Company’s weighted average cost of capital. The resulting range of present enterprise values was adjusted by the Company’s net debt (the face amount of total debt and preferred stock and book value of non-controlling interests less the amount of cash and cash equivalents, as reflected on its most recent publicly available balance sheet) and divided by the number of diluted shares outstanding in order to arrive at a range of present values per share of Company common stock. Raymond James reviewed the range of per share prices derived in the discounted cash flow analysis and compared them to the price per share for Company common stock implied by the merger consideration. The results of the discounted cash flow analysis are summarized below:

Additional Considerations. The preparation of a fairness opinion is a complex process and is not susceptible to a partial analysis or summary description. Raymond James believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering the analyses taken as a whole, would create an incomplete view of the process underlying its opinion. In addition, Raymond James considered the results of all such analyses and did not assign relative weights to any of the analyses, but rather made qualitative judgments as to the significance and relevance of each analysis and factor, so the ranges of valuations resulting from any particular analysis described above should not be taken to be the view of Raymond James as to the actual value of the Company.

In performing its analyses, Raymond James made numerous assumptions with respect to industry performance, general business, economic and regulatory conditions and other matters, many of which are beyond the control of the Company. The analyses performed by Raymond James are not necessarily indicative of actual values, trading values or actual future results which might be achieved, all of which may be significantly more or less favorable than suggested by such analyses. Such analyses were provided to the Company board (solely in its capacity as such) and were prepared solely as part of the analysis of Raymond James of the fairness, from a financial point of view, to the Company shareholders of the merger consideration to be received by such shareholders in connection with the proposed merger pursuant to the merger agreement. The analyses do not purport to be appraisals or to reflect the prices at which companies may actually be sold, and such estimates are inherently subject to uncertainty. The opinion of Raymond James was one of many factors taken into account by the Company board in making its determination to approve the merger.

Neither Raymond James’ opinion nor the analyses described above should be viewed as determinative of the Company board’s or Company management’s views with respect to the Company, Cerberus and its affiliates, or the merger. Raymond James provided advice to the Company with respect to the proposed transaction. Raymond James did not, however, recommend any specific amount of consideration to the Company board or that any specific merger consideration constituted the only appropriate consideration for the merger. The Company placed no limits on the scope of the analysis performed, or opinion expressed, by Raymond James.

97

The Raymond James opinion was necessarily based upon market, economic, financial and other circumstances and conditions existing and disclosed to it on December 10, 2018, and any material change in such circumstances and conditions may affect the opinion of Raymond James, but Raymond James does not have any obligation to update, revise or reaffirm that opinion. Raymond James relied upon and assumed, without independent verification, that there had been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to Raymond James that would be material to its analyses or its opinion, and that there was no information or any facts that would make any of the information reviewed by Raymond James incomplete or misleading in any material respect.

During the two years preceding the date of Raymond James’ written opinion, Raymond James has not been engaged by, performed services for or received any compensation from the Company other than any amounts that were paid to Raymond James under the engagement letter, as it was amended in connection with the current transaction, described in this proxy statement pursuant to which Raymond James was retained as a financial advisor to the Company board to assist in reviewing strategic alternatives. During the two years preceding the date of Raymond James’ written opinion, Raymond James has not been engaged by, performed services for or received any compensation from Cerberus or its affiliates except as follows and as further described in Raymond James’ written opinion, the full text of which is attached as Annex B-1 to this proxy statement: Raymond James received fees of approximately $2.8 million in connection with the sale of a Cerberus portfolio company, Raymond James’s fixed income group earned fees of approximately $163,000 in connection with participation in mortgage-backed underwritings sponsored by a subsidiary of Cerberus, Raymond James’s fixed income institutional sales has earned commissions of $868,000 since January 1, 2016 for trading with various Cerberus funds or accounts, and Raymond James Bank (“RJ Bank”) directly or indirectly holds or recently held certain loan positions regarding Cerberus-affiliated entities which may have provided fees to RJ Bank during the duration of the loan.

For services rendered in connection with the delivery of its opinion, the Company paid Raymond James a customary investment banking fee of $400,000 upon delivery of its opinion. The Company will also pay Raymond James a customary fee for advisory services in connection with the merger of $600,000, $500,000 of which is contingent upon the closing of the merger. The Company also agreed to reimburse Raymond James for its expenses incurred in connection with its services, including the fees and expenses of its counsel, and will indemnify Raymond James against certain liabilities arising out of its engagement. For services rendered in connection with the delivery of an opinion and advisory services in connection with the Ultra transaction, the Company paid Raymond James customary fees totaling $400,000 in July 2017.

The Company retained Raymond James as its financial advisor in connection with the proposed merger based on Raymond James’ experience and reputation. Raymond James is actively involved in the investment banking business and regularly undertakes the valuation of investment securities in connection with public offerings, private placements, business combinations and similar transactions. In the ordinary course of business, Raymond James may trade in the securities of the Company and Cerberus affiliated companies 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. Raymond James may provide investment banking, financial advisory and other financial services to the Company and / or Cerberus and / or its affiliated companies or other participants in the merger in the future, for which Raymond James may receive compensation.

Opinion of Wells Fargo Securities, LLC

On December 11, 2018, Wells Fargo Securities rendered its oral opinion to the Company board (which was subsequently confirmed in writing by delivery of Wells Fargo Securities’ written opinion dated the same date) that, based upon and subject to the procedures followed, qualifications, assumptions and other matters considered in connection with the preparation of its opinion, as of December 11, 2018, the merger consideration to be received by Company shareholders in the merger pursuant to the merger agreement was fair, from a financial point of view, to Company shareholders.

98

Wells Fargo Securities’ opinion was for the information and use of the Company board (in its capacity as such) in connection with its evaluation of the merger. Wells Fargo Securities’ opinion only addressed the fairness, from a financial point of view, to Company shareholders of the merger consideration to be received by such shareholders in the merger pursuant to the merger agreement and did not address any other aspect or implication of the merger. The summary of Wells Fargo Securities’ opinion in this proxy statement is qualified in its entirety by reference to the full text of its written opinion, which is attached as Annex B-2 to this proxy statement and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Wells Fargo Securities in connection with the preparation of its opinion. However, neither Wells Fargo Securities’ written opinion nor the summary of its opinion and the related analyses set forth in this proxy statement is intended to be, and they do not constitute, advice or a recommendation to the Company board or any holder of Company common stock as to how any such holder should vote or act on any matter relating to the proposed merger.

In arriving at its opinion, Wells Fargo Securities:

In connection with its review, Wells Fargo Securities did not independently verify any of the foregoing information, and Wells Fargo Securities assumed and relied upon such information being complete and accurate in all respects. Wells Fargo Securities was advised, and at the Company’s direction assumed, that the Projections were reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company. At the Company’s direction, Wells Fargo Securities further assumed that the Projections were a reasonable basis on which to evaluate the Company and the merger and used and relied upon such forecasts for purposes of its analyses and opinion. Wells Fargo Securities expressed no view or opinion with respect to the Projections or the assumptions upon which they were based.

For purposes of its analyses and opinion, at the Company’s direction, Wells Fargo Securities assumed that, in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on the Company or the contemplated benefits of the merger. Wells Fargo Securities also assumed that the merger would be consummated in compliance with all applicable laws and regulations and in accordance with the terms of the merger agreement without waiver, modification or amendment of any term, condition or agreement thereof material to its analyses or opinion. In addition, Wells Fargo Securities was not requested to make, and did not make, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of the Company, nor was Wells Fargo Securities furnished with any such evaluations or appraisals. With the Company board’s consent, Wells Fargo Securities further assumed that the final form of the merger agreement, when

99

executed by the parties thereto, would conform to the draft reviewed by Wells Fargo Securities in all respects material to its analyses and opinion.

Wells Fargo Securities’ opinion only addressed the fairness, from a financial point of view, to the holders of Company common stock of the merger consideration to be received by such holders in the merger pursuant to the merger agreement and did not address any other aspect or implication (financial or otherwise) of the merger, or any other agreement, arrangement or understanding entered into in connection with the merger or otherwise, including, without limitation, the fairness of the amount or nature of, or any other aspect relating to, any compensation or consideration to be received by or otherwise payable to any officers, directors or employees of any party to the merger, or class of such persons, relative to the merger consideration or otherwise. Furthermore, Wells Fargo Securities did not express any advice or opinion regarding matters that require legal, regulatory, accounting, insurance, tax, environmental, executive compensation or other similar professional advice. Wells Fargo Securities assumed that the Company had or would obtain such advice or opinions from appropriate professional sources.

Wells Fargo Securities’ opinion was necessarily based upon information made available to Wells Fargo Securities as of the date of its opinion and financial, economic, market and other conditions as they existed and could be evaluated on the date of its opinion. Wells Fargo Securities did not undertake, and was under no obligation, to update, revise, reaffirm or withdraw its opinion, or otherwise comment on or consider events occurring or coming to its attention after the date of its opinion. Wells Fargo Securities’ opinion did not address the relative merits of the merger as compared to any alternative transactions or strategies that might have been available to the Company, nor did it address the underlying business decision of the Company board or the Company to proceed with or effect the merger. Wells Fargo Securities did not express any opinion as to the prices at which shares of Company common stock may be purchased or sold at any time.

Under the terms of its engagement, neither Wells Fargo Securities’ opinion nor any other advice or services rendered by it in connection with the proposed merger or otherwise, should be construed as creating, and Wells Fargo Securities will not be deemed to have, any fiduciary, agency or similar duty to the Company board, the Company, Parent, any security holder or creditor of the Company or Parent or any other person, regardless of any prior or ongoing advice or relationships. Under the terms of its engagement, Wells Fargo Securities was retained by the Company as an independent contractor and the opinion and other advice rendered by Wells Fargo Securities were provided solely for the use and benefit of the Company board (in its capacity as such) in connection with its evaluation of the proposed merger. As a matter of state law, Wells Fargo Securities believes the opinion and other advice of Wells Fargo Securities may not be used or relied upon by any other person without its prior written consent. See e.g., Joyce v. Morgan Stanley, 538 F.3d 797 (7th Cir. 2008), HA2003 Liquidating Trust v. Credit Suisse Secs. (USA) LLC, 517 F.3d 454 (7th Cir. 2008) and Collins v. Morgan Stanley Dean Witter, 224 F.3d 496 (5th Cir. 2000). By limiting the foregoing statement to matters of state law, Wells Fargo Securities is not, and should not be deemed to be, admitting that Wells Fargo Securities has any liability to any persons with respect to its advice or opinion under the federal securities laws. Furthermore such statement is not intended to affect the rights and responsibilities of the Company board under governing state law or the federal securities laws. Any claims under the federal securities laws against Wells Fargo Securities or the Company board will be subject to adjudication by a court of competent jurisdiction.

Financial Analyses

In connection with rendering its opinion to the Company board, Wells Fargo Securities performed a variety of analyses, including those described below. The summary of Wells Fargo Securities’ analyses is not a complete description of the analyses underlying Wells Fargo Securities’ opinion. The preparation of such an opinion is a complex process involving various quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytical methods employed and the adaptation and application of these methods to the unique facts and circumstances presented. As a consequence, neither Wells Fargo Securities’ opinion nor its underlying analyses is readily susceptible to summary description. Wells Fargo Securities arrived

100

at its opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any individual analysis, methodology or factor. Accordingly, Wells Fargo Securities believes that its analyses and the following summary must be considered as a whole and that selecting portions of its analyses, methodologies and factors, without considering all analyses, methodologies and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying Wells Fargo Securities’ analyses and opinion.

In performing its analyses, Wells Fargo Securities considered general business, economic, industry and market conditions, financial and otherwise, and other matters as they existed on, and could be evaluated as of, the date of its opinion. No company, transaction or business used in Wells Fargo Securities’ analyses for comparative purposes is identical to the Company or the proposed merger and an evaluation of the results of those analyses is not entirely mathematical. The financial analyses performed by Wells Fargo Securities were performed for analytical purposes only and are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold, which may depend on a variety of factors, many of which are beyond the control of the Company.

While the results of each analysis were taken into account in reaching its overall conclusion with respect to fairness, Wells Fargo Securities did not make separate or quantifiable judgments regarding individual analyses. Much of the information used in, and accordingly the results of, Wells Fargo Securities’ analyses are inherently subject to substantial uncertainty.

Wells Fargo Securities’ opinion was only one of many factors considered by the Company board in evaluating the proposed merger. Neither Wells Fargo Securities’ opinion nor its analyses were determinative of the merger consideration or of the views of the Company board or management with respect to the merger or the merger consideration. The type and amount of consideration payable in the merger were determined through negotiation between the Company and Parent, and the decision to enter into the merger agreement was solely that of the Company board.

The following is a summary of the material financial analyses performed by Wells Fargo Securities in connection with the preparation of its opinion and reviewed with the Company board on December 11, 2018. The order of the analyses summarized below does not represent relative importance or weight given to those analyses by Wells Fargo Securities. The analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the analyses. Considering the data in the tables below without considering the full narrative description of the analyses, as well as the methodologies underlying, and the assumptions, qualifications and limitations affecting, each analysis, could create an incomplete view of Wells Fargo Securities’ analyses.

For purposes of its analyses, Wells Fargo Securities reviewed a number of financial metrics, including the following:

101

Unless the context indicates otherwise, (i) enterprise values used in the selected companies analyses described below were calculated using the market price of the common stock of the selected companies listed below as of December 7, 2018, (ii) the relevant values for the selected transactions analysis described below were calculated on an enterprise value basis based on the consideration proposed to be paid in the selected transactions, and (iii) the estimates of the future financial performance of the Company relied upon for the financial analyses described below were based on the Projections, and estimates of the future financial performance for the selected companies listed below were based on certain publicly available research analyst estimates for those companies.

Selected Companies Analysis. Wells Fargo Securities reviewed certain data for selected companies with publicly traded equity securities that Wells Fargo Securities deemed relevant. The selected companies were selected because they were deemed similar to the Company’s ECP or MDS businesses in one or more respects.

The financial data reviewed included:

The selected companies for the Company’s ECP business and the corresponding and median Enterprise Value to CY 2019E Adj. EBITDA multiples for the selected companies were:

The selected companies for the Company’s MDS business and the corresponding and median Enterprise Value to CY 2019E Adj. EBITDA multiples for the selected companies were:

102

The corresponding and the mean, median, high and low share price to CY 2019E Adj. EPS multiples for all of the selected companies identified above were:

Taking into account the results of the selected companies analysis, Wells Fargo Securities added the amount that resulted from applying a multiple range of 8.3x to 9.3x to CY 2019E Adj. EBITDA for the Company’s ECP business to the amount that resulted from applying a multiple range of 4.3x to 5.3x to CY 2019E Adj. EBITDA for the Company’s MDS business and deducted the amount that resulted from applying a multiple range of 7.1x to 8.1x (reflecting a weighted average multiple based on the relative contribution of the Company’s ECP and MDS businesses, respectively, to the Company’s CY 2019E Adj. EBITDA) to CY 2019E Adj. EBITDA attributable to the Company’s unallocated corporate overhead. Wells Fargo Securities also applied a multiple range of 14.0x to 16.0x to CY 2019E Adj. EPS for the Company. The selected companies analysis indicated implied valuation reference ranges per share of Company common stock of $11.36 to $13.99 based on the Company’s CY 2019E Adj. EBITDA and $8.66 to $9.90 based on the Company’s CY 2019E Adj. EPS. Wells Fargo Securities noted that the merger consideration to be paid in the merger pursuant to the merger agreement is $18.50 per share of Company common stock.

Selected Transactions Analysis. Wells Fargo Securities considered certain financial terms of certain transactions involving target companies that Wells Fargo Securities deemed relevant. The selected transactions were selected because they involved target companies that were deemed similar to the Company’s ECP or MDS businesses in one or more respects.

The financial data reviewed included Enterprise Value as a multiple of Adjusted EBITDA for the last twelve months prior to the announcement of the applicable transaction for which data was publicly available, or “LTM Adj. EBITDA.”

103

The selected transactions for the Company’s ECP business and the corresponding and mean and median Enterprise Value to LTM Adjusted EBITDA multiples, to the extent publicly available, for the selected transactions were:

The selected transactions for the Company’s MDS business and the corresponding and mean and median Enterprise Value to LTM Adjusted EBITDA multiples, to the extent publicly available, for the selected transactions were:

Taking into account the results of the selected transactions analysis, Wells Fargo Securities added the amount that resulted from applying a multiple range of 9.5x to 10.5x to Adjusted EBITDA for the last twelve months

104

ended September 30, 2018 for the Company’s ECP business to the amount that resulted from applying a multiple range of 6.0x to 7.0x to Adjusted EBITDA for the last twelve months ended September 30, 2018 for the Company’s MDS business and deducted the amount that resulted from applying a multiple range of 8.8x to 9.8x (reflecting a weighted average multiple based on the relative contribution of the Company’s ECP and MDS businesses, respectively, to the Company’s LTM Adjusted EBITDA) to Adjusted EBITDA for the last twelve months ended September 30, 2018 attributable to the Company’s unallocated corporate overhead. The selected transactions analysis indicated an implied valuation reference range per share of Company common stock of $24.00 to $27.55. Wells Fargo Securities noted that the merger consideration to be paid in the merger pursuant to the merger agreement is $18.50 per share of Company common stock.

Discounted Cash Flow Analysis. Wells Fargo Securities also performed a discounted cash flow analysis with respect to the Company. Wells Fargo Securities calculated the estimated net present value of the projected unlevered, after-tax free cash flows of the Company based on the Projections. For purposes of the discounted cash flow analyses, Wells Fargo Securities applied discount rates (selected based on Wells Fargo Securities’ experience and judgment and an estimate of the Company’s weighted average cost of capital) ranging from 11.5% to 12.5% and terminal value multiples (selected based on Wells Fargo Securities’ experience and judgment) ranging from 8.5x to 10.0x to management estimates of fiscal year 2023 Adjusted EBITDA, referred to as “Management EBITDA” in the unaudited financial information provided above beginning on page 86. The discounted cash flow analysis indicated an implied valuation reference range per share of Company common stock of $15.48 to $19.51. Wells Fargo Securities noted that the merger consideration to be paid in the merger pursuant to the merger agreement is $18.50 per share of Company common stock.

Other Matters

The Company retained Wells Fargo Securities as its financial advisor in connection with the proposed merger based on Wells Fargo Securities’ experience and reputation. Wells Fargo Securities is regularly engaged to provide investment banking and financial advisory services in connection with mergers and acquisitions, financings, and financial restructurings. Wells Fargo Securities became entitled to an opinion fee of $750,000 upon the rendering of its opinion. Wells Fargo Securities will also become entitled to receive a transaction fee, currently estimated to be approximately $2.25 million, based on the implied value of the proposed merger, upon the closing of the merger against which the opinion fee and certain advisory fees will be creditable to the extent previously paid. In addition, the Company agreed to reimburse Wells Fargo Securities for certain expenses and to indemnify Wells Fargo Securities and certain related parties against certain liabilities that may arise out of Wells Fargo Securities’ engagement. In addition, Wells Fargo Securities acted as financial advisor to the Company board in connection with the transaction contemplated by the Ultra merger agreement, which agreement was terminated without consummation of the Ultra transaction, for which Wells Fargo Securities received aggregate fees of approximately $900,000 for providing certain advice and its opinion in connection therewith.

Wells Fargo Securities is a trade name of Wells Fargo Securities, LLC, an investment banking subsidiary and affiliate of Wells Fargo & Company. Wells Fargo Securities and its affiliates provide a wide range of investment and commercial banking advice and services, including financial advisory services, securities underwritings and placements, securities sales and trading, brokerage advice and services, and commercial loans. Wells Fargo Securities and its affiliates may in the future provide investment and commercial banking advice and services to, and may otherwise seek to expand their business and commercial relationships with the Company and certain of its affiliates for which Wells Fargo Securities and its affiliates would expect to receive compensation. Wells Fargo Securities and its affiliates have in the past provided investment and commercial banking advice and services to Cerberus (which we refer to together with its portfolio companies and other entities affiliated or associated with Cerberus as the “Cerberus Group”) and certain members of the Cerberus Group, including among other things, during the past two years, having provided certain debt and equity underwriting and real estate related advisory services to portfolio companies in the Cerberus Group that are unrelated to the merger and having acted as co-manager in connection with credit facilities of members of the Cerberus Group, for which Wells Fargo Securities and its affiliates have received compensation of approximately $19.5 million. Wells Fargo

105

Securities and its affiliates are also lenders to or participants in one or more of the credit facilities of the Company and its affiliates and of certain members of the Cerberus Group, including CIP VI. With respect to the credit facility of CIP VI, prior to the execution of the merger agreement, Wells Fargo Securities understood after discussions with representatives of Cerberus and informed the Company board that the members of the Cerberus Group did not intend to finance the merger by making borrowings under such facility. Wells Fargo Securities and its affiliates may in the future otherwise seek to expand its business and commercial relationships with members of the Cerberus Group, for which Wells Fargo Securities and its affiliates would expect to receive compensation. In the ordinary course of business, Wells Fargo Securities and its affiliates may trade or otherwise effect transactions in the securities or other financial instruments (including bank loans or other obligations) of the Company, Cerberus and/or their respective affiliates 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 or financial instruments. Wells Fargo Securities and its affiliates have adopted policies and procedures designed to preserve the independence of their research and credit analysts whose views may differ from those of the members of the team of investment banking professionals involved in preparing Well Fargo Securities’ opinion. The issuance of Wells Fargo Securities’ opinion was approved by an authorized committee of Wells Fargo Securities.

Financing of the Merger

The obligations of Parent and Merger Sub to complete the merger are not contingent upon the receipt of any financing.

Financing

CIP VI, which is an affiliate of Cerberus, and Parent have entered into the equity commitment letter, pursuant to which CIP VI committed to purchase securities of Parent for $280 million in cash substantially contemporaneously with the consummation of the merger. Such commitment amount is subject to reduction if Parent does not require the entire amount to pay the aggregate merger consideration and all amounts required to be paid with respect to the Company’s equity awards, to repay or refinance the indebtedness of the Company to the extent required in connection with the transactions contemplated by the merger agreement, and to pay the fees and expenses of Parent, Merger Sub and the surviving corporation in connection with the merger and the transactions contemplated by the merger agreement (which we refer to, collectively, as the “required payments”).

CIP VI’s obligation to make the investment pursuant to the equity commitment letter is subject to (a) the valid execution and delivery of the merger agreement by all parties to the merger agreement and the merger agreement not having been terminated, (b) the satisfaction, or waiver by Parent, of each of the conditions to Parent’s obligations to consummate the transactions contemplated by the merger agreement set forth in the merger agreement and (c) the substantially contemporaneous consummation of the merger in accordance with the terms of the merger agreement.

The equity commitment letter will terminate upon, among other events, the closing of the merger, valid termination of the merger agreement, the Company’s bringing certain legal proceedings against CIP VI or certain of its affiliates relating to the equity commitment letter, the merger agreement, the limited guarantee or any of the transactions contemplated thereby, or the payment of all the obligations of CIP VI under the limited guarantee.

The equity commitment letter provides, among other things, that (a) if the Company becomes entitled to specific performance under the merger agreement to cause Parent to obtain the equity financing, then the Company is an express third party beneficiary of Parent’s rights under the equity commitment letter solely for the purpose of causing the investment to be made pursuant to its terms and (b) the Company is an express third party beneficiary of the confidentiality provisions of the equity commitment letter. In addition, the merger agreement provides that Parent and Merger Sub will maintain in effect the equity commitment letter in accordance with its terms and subject to its conditions, or on such other terms as are permitted by the merger agreement or agreed to in writing by the Company.

106

In the merger agreement, Parent and Merger Sub have represented that the equity financing, when funded in accordance with its terms, will provide Parent with funds sufficient to satisfy, or cause to be satisfied, the required payments.

Parent also plans to finance a portion of the amounts required to complete the merger through a debt financing, which is expected to take the form of a revolving credit facility and a term loan facility. Subject to customary terms, the Company has agreed to, and to cause its subsidiaries to, provide Parent with customary cooperation as reasonably requested by Parent or Merger Sub to assist them in arranging such debt financing.

Limited Guarantee

To induce the Company to enter into the merger agreement, CIP VI executed the limited guarantee, dated as of December 11, 2018, in favor of the Company. Under the limited guarantee, subject to the limitations described therein, CIP VI has absolutely, irrevocably and unconditionally guaranteed to the Company the due and punctual payment of Parent’s obligations under the merger agreement to (a) pay the Parent termination fee under the circumstances provided in the merger agreement, (b) pay all reasonable out-of-pocket costs, fees and expenses (including reasonable legal fees and expenses) incurred by the Company in connection with the enforcement of Parent’s obligation to pay the Parent termination fee pursuant to the merger agreement, and (c) reimburse the Company for certain expenses and indemnify the Company against certain losses in connection with the Company’s financing cooperation covenants under the merger agreement (collectively, the “Obligations”). CIP VI is also obligated to pay all reasonable out-of-pocket costs, fees and expenses (including reasonable legal fees and expenses) incurred by the Company in connection with the enforcement of CIP VI’s obligation to satisfy the Obligations (the “Reimbursement”). CIP VI’s liability under clause (a) above shall not exceed $9,250,000, and its liability under clauses (b) and (c) above and with respect to the Reimbursement is subject to a maximum of $1,500,000.

The limited guarantee terminates upon the earliest of (a) the consummation of the transactions contemplated by the merger agreement, (b) the date on which all of the Obligations are fully satisfied and the Reimbursement is fully paid in accordance with the terms of the merger agreement or the limited guarantee, (c) the date on which the Company initiates certain legal proceedings related to the limited guarantee against certain affiliates of CIP VI (other than Parent or Merger Sub), and (d) the date that is 90 days after the merger agreement is terminated in accordance with its terms, except that, in the case of clause (d), the limited guarantee will not terminate at the end of such 90-day period if the Company has commenced a legal proceeding to enforce its rights with respect to the Obligations or the Reimbursement in which case the limited guarantee will terminate upon the earliest of (i) a final non appealable resolution of such proceeding by the relevant court and the payment or satisfaction of all of the obligations imposed by such court or (ii) a written agreement by CIP VI and the Company resolving such claims.

Interests of the Company’s Executive Officers and Directors in the Merger

In considering the recommendation of the Company board with respect to the merger, you should be aware that the Company’s directors and executive officers have certain interests in the merger that may be different from, or in addition to, the interests of the other Company shareholders. The Company board was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the merger, and in determining to recommend to Company shareholders that they vote for the merger proposal and thereby approve the transactions contemplated by the merger agreement, including the merger. These interests are described below.

The amounts described below are estimates based on multiple assumptions that may or may not actually occur, including assumptions described in this proxy statement, and do not reflect certain compensation actions that may occur before the consummation of the merger. As a result, the actual amounts, if any, to be received by the executive officers and non-employee directors may materially differ from the amounts set forth below. All dollar amounts have been rounded to the nearest whole dollar.

107

Treatment of Company Equity Awards

The restricted stock, restricted stock units and stock options (which we collectively refer to as the “Company equity awards”) held by the Company’s employees, including the Company’s executive officers, and by directors of the Company immediately prior to the effective time will be cancelled in exchange for a cash payment in the same manner as those Company equity awards held by other employees of the Company. As described further in the section titled “The Merger Agreement—Treatment of Company Equity Awards,” such awards will be subject to the following treatment:

All stock options held by the Company’s named executive officers, other executive officers and directors that are vested or are scheduled to be vested or accelerated in connection with the merger as of the date of this proxy statement have an exercise price greater than $18.50 per share and, therefore, no named executive officers, other executive officers or directors will receive compensation for their stock options in connection with the merger. In addition, as of the date of this proxy statement no restricted shares under Company stock plans are outstanding. Further information regarding the named executive officers may be found in “—Golden Parachute Compensation” beginning on page 115.

108

The table below sets forth certain information (without subtraction of applicable withholding taxes) of the Company RSUs held by the Company’s executive officers and directors for which vesting will be accelerated in connection with the merger.

The Company’s Employment Arrangements with Named Executive Officers

Each of the Company’s named executive officers is party to an employment agreement with the Company (each, an “employment agreement” and, collectively, the “employment agreements”). A brief summary of the employment agreements of named executive officers and potential payments upon termination or change in control is set out below.

On December 11, 2018, the Company board approved the grant of a discretionary bonus to Mr. Hartnett in the amount of $385,000.
