61,470,344 shares of Common Stock; options to purchase 108,517 shares of Common Stock; and restricted stock units with respect to 252,878 shares of Common Stock.

The maximum aggregate value was determined based upon the sum of (A) 61,470,344 shares of Common Stock multiplied by $1.85 per share; (B) options to purchase 108,517 shares of Common Stock multiplied by $1.3408 (which is the difference between $1.85 and the weighted average exercise price of $0.5092 per share); and (C) restricted stock units with respect to 252,878 shares of Common Stock multiplied by $1.85 per share. In accordance with Section 14(g) of the Securities Exchange Act of 1934, as amended, the filing fee was determined by multiplying 0.0000558 by the sum of the numbers in the preceding sentence.

The board of directors of Entrust, Inc., a Maryland corporation, has approved a merger agreement providing for the acquisition of Entrust by HAC Holdings, Inc., an entity controlled by a private equity fund associated with Thoma Bravo, LLC.

Our board of directors has determined that the merger is fair to and in the best interests of Entrust and its stockholders and recommends that you vote “FOR” the approval of the merger.

Your vote is very important. We cannot complete the merger unless the approval of the merger is approved by the affirmative vote of two-thirds of the votes entitled to be cast by the holders of the outstanding shares of Entrust Common Stock. The failure of any stockholder to vote on the proposal to approve the merger will have the same effect as a vote against the approval of the merger.

HAC Holdings, Inc., which we refer to as Newco, is a Delaware corporation that was formed solely for the purpose of acquiring Entrust and has not engaged in any business except for activities incidental to its formation and as contemplated by the Merger Agreement.

Upon the consummation of the Merger, Newco will be owned by a private equity fund associated with Thoma Bravo, LLC.

HAC Acquisition Corporation, which we refer to as Merger Sub, is a Maryland corporation that was organized solely for the purpose of completing the proposed Merger. Merger Sub is a wholly owned subsidiary of Newco and has not engaged in any business except for activities incidental to its formation and as contemplated by the Merger Agreement. Upon the consummation of the proposed Merger, Merger Sub will cease to exist and Entrust will continue as the Surviving Corporation.

The Agreement and Plan of Merger by and among NewCo, Merger Sub and the Company (the “Merger Agreement”) provides that Merger Sub will merge with and into the Company (the “Merger”). The Company will be the surviving corporation in the Merger (the “Surviving Corporation”) and will continue to do business as “Entrust, Inc.” following the Merger. In the Merger, each outstanding share of the Company’s Common Stock (other than shares owned by the Company, Newco or Merger Sub), will be cancelled and extinguished and converted into the right to receive $1.85 in cash, without interest and less any applicable withholding tax, which amount we refer to in this proxy statement as the merger consideration.

If the Merger is completed, you will be entitled to receive $1.85 in cash, without interest and less any applicable withholding taxes, for each share of the Company’s Common Stock owned by you. As a result of the Merger, Entrust will cease to be an independent, publicly traded company. You will not own any shares of the Surviving Corporation.

The special meeting will be held on —, 2009, starting at — a.m. local time, at —.

You will be asked to consider and vote upon the approval of the Merger, pursuant to which Merger Sub will merge with and into the Company.

You are entitled to vote at the special meeting if you owned shares of the Company’s Common Stock at the close of business on —, 2009, the record date for the special meeting. You will have one vote for each share of the Company’s Common Stock that you owned on the record date. As of the record date there were — shares of the

Company’s Common Stock outstanding and entitled to vote. The presence in person or by proxy of stockholders entitled to cast a majority of all votes entitled to be cast at the special meeting shall constitute a quorum for the purpose of considering the proposals.

The approval of the Merger requires the affirmative vote of two-thirds of the votes entitled to be cast by the holders of the outstanding shares of the Company’s Common Stock. Approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of a majority of the votes cast on the matter at the special meeting.

As of the record date, the directors and executive officers of the Company held —% in the aggregate of the shares of the Company’s Common Stock entitled to vote at the special meeting. In the aggregate, these shares represent —% of the voting power necessary to approve the Merger at the special meeting.

Any stockholder of record entitled to vote at the special meeting may authorize a proxy by telephone, the Internet, by returning the enclosed proxy card by mail, or by voting in person by appearing at the special meeting. If your shares of the Company’s Common Stock are held in “street name” by your broker, you should instruct your broker on how to vote your shares of the Company’s Common Stock using the instructions provided by your broker. If you do not provide your broker with instructions, your shares of the Company’s Common Stock will not be voted and that will have the same effect as a vote “AGAINST” the approval of the Merger. The persons named in the accompanying proxy will also have discretionary authority to vote on any adjournments or postponements of the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies.

Any stockholder of record who executes and returns a proxy card (or authorizes a proxy via telephone or the Internet) may revoke the proxy at any time before it is voted at the special meeting in any one of the following ways:

Upon the consummation of the Merger, each then outstanding Company option, including unvested Company options, shall be cancelled, and exchanged (A) in the case of any Company option that is vested in accordance with the terms of the applicable Company Stock Plan and has a per share exercise price less than $1.85, for the right to receive from the Surviving Corporation for each share of the Company’s Common Stock

subject to such Company option immediately prior to the consummation of the Merger, an amount (subject to any applicable withholding tax) in cash equal to the product of (x) the number of shares of the Company’s Common Stock subject to such Company option immediately prior to the consummation of the Merger and (y) the amount by which $1.85 exceeds the per share exercise price of such Company option, or (B) in the case of any Company option having a per share exercise price equal to or greater than $1.85 or any unvested Company option, without the payment of cash or issuance of other securities in respect thereof. Newco shall, or shall cause the Company to, pay to holders of eligible Company options the option consideration, without interest thereon, less applicable taxes required to be withheld with respect to these payments.

Upon the consummation of the Merger, each right of any kind to receive shares of the Company’s Common Stock or benefits measured by the value of a number of shares of the Company’s Common Stock, and each award of any kind consisting of shares of the Company’s Common Stock, in each case, granted under the Company Stock Plans (including restricted stock units, stock appreciation rights and performance stock units) other than Company Options (each of these awards is sometimes referred to in this proxy statement as a Company stock-based award), whether or not then vested, shall become fully vested and shall be converted automatically into the right to receive upon the consummation of the Merger an amount in cash in U.S. dollars equal to the product of (x) the total number of shares of the Company’s Common Stock subject to such Company stock-based award and (y) $1.85 (reduced, if applicable, by any exercise or base price applicable to such Company stock-based award) and each Company stock-based award shall be cancelled and shall only entitle the holder thereof to the payment described above.

The board of directors recommends that our stockholders vote “FOR” the approval of the Merger and “FOR” the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies. For a discussion of the material factors considered by the board of directors in reaching its conclusions, see “The Merger—Reasons for the Merger; Special Committee, Recommendation of Our Board of Directors” beginning on page 36.

Notwithstanding the financing arrangements that Newco has in place, the consummation of the Merger is not subject to any financing conditions (although funding of the equity and debt financings is subject to the satisfaction of the conditions set forth in the commitment letters under which the financings will be provided). See “The Merger Agreement—Financing” beginning page 73. The following arrangements are in place for the financing of the Merger, including the payment of related transaction costs, charges, fees and expenses:

Equity Financing. Newco and Merger Sub have received an equity commitment letter from Thoma Bravo Fund IX, L.P. (referred to in this proxy statement as the Investor) to provide equity financing in an aggregate amount sufficient to fully finance the Merger and other transactions contemplated by the Merger Agreement.

Debt Financing. Newco has received a debt commitment letter from Wells Fargo Foothill, LLC and Bank of Montreal (jointly referred to in this proxy statement as the Lenders), pursuant to which, and subject to the conditions of that letter, the Lenders have agreed to provide to the Company a $52 million senior secured credit facility.

Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the rules promulgated thereunder by the Federal Trade Commission (“FTC”), the Merger may not be completed until notification and report forms have been filed with the FTC and the Antitrust Division of the Department of Justice (“DOJ”), and the applicable waiting period has expired or been terminated.

If Newco terminates the Merger Agreement, at any time prior to the consummation of the Merger, because we failed to obtain the requisite stockholder approval at the meeting of the Company stockholders at which a vote is taken on the Merger, then we must pay to Newco an amount equal to the costs and expenses incurred by Newco and Merger Sub in connection with the negotiation of the Merger Agreement, up to a maximum amount of $1,000,000.

The Company is entitled to seek an injunction to prevent or restrain breaches or threatened breaches of the Merger Agreement, the equity commitment letter or the guarantee, and to enforce specifically the terms of the Merger Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of Newco and Merger Sub under the Merger Agreement, the equity commitment letter and the guarantee.

Upon the consummation of the Merger, Newco will be owned by a private equity fund associated with Thoma Bravo, LLC.

This proxy statement is being furnished to our stockholders as part of the solicitation of proxies by our board of directors for use at the special meeting to be held on —, 2009, starting at — a.m. local time, at the —, or at any postponement or adjournment thereof. The purpose of the special meeting is for our stockholders to consider and vote upon approval of the Merger of the Company substantially as set forth in the Merger Agreement (and to approve the adjournment of the special meeting, if necessary or appropriate to solicit additional proxies). Our stockholders must approve the Merger in order for the Merger to occur. If we do not receive the requisite vote of our stockholders to approve the Merger, the Merger will not occur. A copy of the Merger Agreement is attached to this proxy statement as Annex A. This proxy statement and the enclosed form of proxy are first being mailed to our stockholders on —, 2009.

We have fixed the close of business on —, 2009 as the record date for the special meeting, and only holders of record of the Company’s Common Stock on the record date are entitled to vote at the special meeting. On the record date, there were — shares of the Company’s Common Stock outstanding and entitled to vote. Each share of the Company’s Common Stock entitles its holder to one vote on all matters properly coming before the special meeting.

A majority of the total voting power of the Company’s Common Stock issued, outstanding and entitled to vote at the special meeting constitutes a quorum for the purpose of considering the proposals. Shares of the Company’s Common Stock represented at the special meeting but not voted, including shares of the Company’s Common Stock for which proxies have been received but for which stockholders have abstained, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business. In the event that a quorum is not present at the special meeting, it is expected that the meeting will be adjourned or postponed to solicit additional proxies.

Approval of the Merger requires the affirmative vote of the holders of two-thirds of the outstanding shares of the Company’s Common Stock. For the proposal to approve the Merger, you may vote FOR, AGAINST or ABSTAIN. Abstentions will not be counted as votes cast or shares voting on the proposal to approve the Merger, but will count for the purpose of determining whether a quorum is present. If you abstain, it will have the same effect as a vote “AGAINST” the approval of the Merger.

Under the rules of the NASDAQ, brokers who hold shares in “street name” for customers have the authority to vote on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are precluded from exercising their voting discretion with respect to approving non-routine matters such as the approval of the Merger and, as a result, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote those shares, referred to generally as “broker non-votes.” These “broker non-votes” will be counted for purposes of determining a quorum, but will have the same effect as a vote “AGAINST” the approval of the Merger.

On April 12, 2009, the Company and certain directors and officers, in their individual capacities, along with selected stockholders (including Empire Capital, Arcadia Opportunity Master Fund, Ltd. and certain affiliated entities), (referred to in this proxy statement as the selected stockholders), entered into voting agreements pursuant to which the selected stockholders agreed to vote in favor of the adoption and approval of the Merger Agreement, the Merger and the transactions contemplated by the Merger Agreement. In addition, the selected stockholders agreed not to directly or indirectly transfer their respective shares of the Company’s Common Stock

during the term of their respective voting agreement. As of —, 2009, the record date, the selected stockholders held and are entitled to vote, in the aggregate, — shares of the Company’s Common Stock, representing —% of the outstanding Company’s Common Stock. The selected stockholders include all directors and executive officers of the Company with the exception of director Douglas Schloss.

If you submit a proxy by returning a signed proxy card by mail, your shares will be voted at the special meeting as you indicate on your proxy card or by such other method. If you sign your proxy card without indicating your vote, your shares will be voted “FOR” the adoption of the Merger Agreement and “FOR” the adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies, and in accordance with the recommendations of our board of directors on any other matters properly brought before the special meeting for a vote.

If your shares of the Company’s Common Stock are held in “street name,” you will receive instructions from your broker, bank or other nominee that you must follow in order to have your shares voted. If you do not instruct your broker to vote your shares, it has the same effect as a vote against adoption of the Merger Agreement.

Proxies received at any time before the special meeting, and not revoked or superseded before being voted, will be voted at the special meeting. You have the right to change or revoke your proxy at any time before the vote taken at the special meeting:

Please do not send in your stock certificates with your proxy card. When the Merger is completed, a separate letter of transmittal will be mailed to you that will enable you to receive the merger consideration in exchange for your stock certificates.

Although it is not currently expected, the special meeting may be adjourned or postponed for the purpose of soliciting additional proxies. Any adjournment may be made without notice (if the adjournment is not for more than 20 days after the record date), other than by an announcement made at the special meeting of the time, date and place of the adjourned meeting. Whether or not a quorum exists, holders of a majority of the combined voting power of the Company’s Common Stock present in person or represented by proxy at the special meeting and entitled to vote thereat may adjourn the special meeting. Any signed proxies received by Entrust in which no voting instructions are provided on such matter will be voted “FOR” an adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies. Any adjournment or postponement of the special meeting for the purpose of soliciting additional proxies will allow Entrust’s stockholders 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.

This proxy solicitation is being made and paid for by Entrust on behalf of its board of directors. In addition, we have retained — to assist in the solicitation. We will pay — $— plus reasonable out-of-pocket expenses for their assistance. Our directors, officers and employees may also solicit proxies by personal interview, mail, e-mail,

telephone, facsimile or other means of communication. These persons will not be paid additional remuneration for their efforts.

Our board of directors and management team have been regularly evaluating our business and operations, our long-term strategic goals and alternatives, and our prospects as an independent company since our initial public offering in August 1998. Our board of directors and management team recognize that we operate in an industry that is highly competitive and subject to constant and rapid technological change, product obsolescence, price erosion, evolving standards and short life-cycles for certain products. Throughout the history of our Company, our board of directors and management team have regularly reviewed and assessed trends and conditions impacting the Company and the information security industry, changes in the marketplace and applicable law, the competitive environment and the future prospects of the Company.

As the information security industry has matured, the manner in which organizations view security and how it applies to their business has changed. Today, the information security industry is characterized by rapidly changing customer requirements and continual technological evolution. Many of the Company’s competitors are significantly larger than the Company and have greater market capitalizations and resources to develop new technologies and stay abreast of technological innovations in the marketplace. Recently, large information technology, or “IT,” vendors have become more focused on information security, and are beginning to offer free or discounted security solutions as part of a broader platform. Additionally, software security solutions are now being “bundled” by certain larger providers with other software and hardware solutions, which forces the Company to compete at a disadvantage against these types of “packaged bundles” of software solutions. Because the information security industry is still relatively young and has been subject to rapid change, it has historically been very difficult for participants in this industry, including the Company, to achieve and maintain profitability and revenue growth. For example, the Company was cash flow positive in fiscal year 2005, but operated at a net loss for fiscal years 2006, 2007 and 2008.

As part of its ongoing review of the Company and its position in the information security industry, our board of directors also regularly reviews the strategic alternatives available to the Company, including, among things, possible strategic combinations, acquisitions and divestitures. In the fall of 2005, as part of this ongoing review process, our board of directors and management team determined to pursue a strategy of growth pursuant to which the Company would seek to complete strategic acquisitions to expand its business. Thereafter, the Company successfully completed several acquisitions, which contributed to the Company’s increase in revenues for 2007 over the prior year.

Although the Company was able to increase its revenues in 2007, at the same time the information security industry continued to evolve rapidly. As large IT vendors and other competitors of the Company react to their customers’ desire for new security solutions, these companies have actively sought to provide security solutions by leveraging their existing product portfolios and customer base. Additionally, consolidation has continued to occur rapidly within the industry. In light of these market dynamics and pressures, our board of directors and management team has been actively evaluating ways for the Company to remain competitive and to continue to increase its revenues and financial performance. This evaluation is one of several factors considered by our board of directors as part of its ongoing review of strategic alternatives available to the Company.

As part of its ongoing review process, on July 27, 2007, our board of directors met and directed our management team to screen potential financial advisors to assist our board of directors with its evaluation of various strategic alternatives for the Company. Acting on this direction, our management team interviewed several financial advisors, narrowed the group of potential financial advisors down to two candidates, provided

the candidates with information about the Company so that each could submit proposals regarding the strategic direction of the Company to our board of directors and set up preliminary meetings between the two candidates and our board of directors.

On September 14, 2007, our board of directors met with the two potential financial advisors to evaluate strategic alternatives available to the Company. Our board of directors discussed, among other things, the Company’s current market position, the competitive landscape of the information security industry, the challenges currently facing the Company and challenges expected to arise in the future, and a preliminary framework for valuing the Company. As part of this discussion, our board of directors discussed various strategic alternatives available to the Company and the potential benefits and challenges associated with each, including the following: a strategic sale of the Company, a merger of equals, acquiring additional products, continuing to operate as a stand-alone entity, restructuring the Company’s business (including the possible divestiture of non-core assets) and a leveraged buyout transaction. Our board of directors instructed our management team to continue evaluating potential strategic alternatives available to the Company and assessing financial advisors.

On September 27, 2007, Robert Sayle of Thoma Bravo, a private equity firm, contacted F. William Conner, our Chief Executive Officer, expressing Thoma Bravo’s interest in exploring an acquisition of the Company and using the Company as a platform to make further strategic acquisitions. Mr. Conner, in turn, forwarded the email to David Rockvam, our Vice President Corporate Business Development. No other action was taken by Mr. Rockvam.

Between late September and late November 2007, members of our management team engaged in discussions with a financial advisor regarding a potential strategic transaction or other business combination, but these discussions did not result in an indication of interest or offer from the interested party.

On October 15, 2007, our board of directors convened a special meeting to review and discuss the strategic alternatives available to the Company with representatives of management and representatives of Lehman Brothers Inc. (“Lehman Brothers”). During this meeting, our board of directors approved the engagement of Lehman Brothers as the Company’s financial advisor to assist the Company in exploring various strategic alternatives available to the Company, including a sale of the Company (regardless of the identity of the buyer), a strategic merger or other business combination transaction, and continuing to execute on the Company’s existing business plan. Subsequently, on October 19, 2007, the Company executed a written engagement letter with Lehman Brothers.

Beginning on October 29, 2007 and in the weeks that followed, representatives from Lehman Brothers and our management team met several times to discuss strategic alternatives available for the Company and the likely universe of third parties who might be interested in a strategic merger or other business combination transaction involving the Company. Representatives of Lehman Brothers approached these third parties to gauge their interest in a possible strategic transaction involving the Company.

On November 29, 2007, our board of directors held a regularly scheduled meeting. Also present were members of the Company’s management team, representatives from Lehman Brothers and a representative of Sullivan & Cromwell. The representatives of Lehman Brothers noted that the Company had received a verbal indication of interest from a potential strategic partner. Our board of directors discussed, among other things, the Company’s stock price and trading performance, the Company’s historical operating and financial results, economic and industry conditions generally, including industry consolidation, the significant challenges facing the Company in continuing to increase revenue and scale its business, the Company’s prospects as a stand-alone entity and other potential strategic alternatives available to the Company. After discussion, our board of directors instructed representatives of Lehman Brothers and the Company’s management team to consider in more depth the strategic alternatives available to the Company in comparison to the Company’s existing business plans and prospects and to continue discussions with third parties potentially interested in a strategic transaction with the Company. Our board of directors also instructed management to work with Lehman Brothers to prepare an

analysis of the strategic alternatives available to the Company, including a sale of the Company (regardless of the identity of the buyer), a strategic merger or other business combination transaction and continuing to execute on the Company’s existing business plans.

Earlier that same day, on November 29, 2007, Mr. Conner had discussions with a potential strategic partner regarding a possible strategic merger or other business combination and, after the board meeting, received a letter of interest from the potential strategic partner.

Following the November 29, 2007 meeting of our board of directors, our management team and representatives of Lehman Brothers had additional meetings to discuss the strategic alternatives available to the Company. Lehman Brothers continued to identify potential purchasers and, on behalf of the Company, coordinated efforts to negotiate confidentiality and standstill agreements with a number of parties.

Over the course of December 2007, management held meetings with and made presentations to the potentially interested parties identified by Lehman Brothers.

On or about January 5, 2008, as directed by our board of directors, Lehman Brothers contacted the potentially interested parties and requested that each provide a preliminary indication of interest by no later than January 23, 2008. During the period leading up to January 23, 2008, our management team continued to conduct management presentations for these potentially interested parties.

Pursuant to Lehman Brothers request, on January 23, 2008, certain of the interested parties delivered preliminary non-binding indications of interest for the acquisition of the Company and on January 24, 2008, our board of directors held a regularly scheduled meeting during which it reviewed the bids. Also present were members of the Company’s management team, representatives from Lehman Brothers and a representative of the Company’s outside legal counsel. The representatives of Lehman Brothers provided an update on discussions with third parties regarding a possible strategic transaction with the Company, reviewed the preliminary non-binding indications of interest that had been submitted by potentially interested parties and discussed possible next steps in the process. A representative of the Company’s outside legal counsel provided an overview of the duties applicable to the board of directors in the context of considering a proposed business combination transaction and also discussed potentially applicable regulatory matters. Our board of directors discussed, among other things, the Company’s stock price and trading performance, the Company’s historical operating and financial results, economic and industry conditions generally, including industry consolidation, the significant challenges facing the Company in continuing to increase revenue and scale its business, the Company’s prospects as a stand-alone entity and other potential strategic alternatives available to the Company. Our board of directors then instructed Lehman Brothers to continue the ongoing discussions with interested parties, with the goal of soliciting more favorable terms for, and more concrete indications of interest in, a business combination transaction with the Company.

At this meeting our board of directors also discussed the formal engagement of legal counsel in connection with the evaluation of a proposed business combination transaction and determined that both of the firms the Company significantly relied on for corporate matters were familiar with the Company, reputable, and highly qualified to advise them in this context, and instructed the Company’s management team to negotiate for competitive fee arrangements with the firms. Thereafter, our management team, at the direction of our board of directors, formally retained Wilson Sonsini Goodrich & Rosati, Professional Corporation, to assist the board of directors with its evaluation of various strategic alternatives available to the Company in February 2008.

Subsequent to the January 24 meeting of our board of directors, our management team and Lehman Brothers continued to conduct discussions with existing bidders and those potentially interested parties that had already been identified as well as other potentially interested parties, entered into additional confidentiality agreements and were successful in obtaining an additional indication of interest letter from an interested party and oral indications of interest from two other interested parties. Over the next several weeks, certain of these parties conducted due diligence on the Company.

On March 3, 2008, our board of directors held a regularly scheduled meeting. Also present were members of the Company’s management team, representatives from Lehman Brothers and representatives of Wilson Sonsini Goodrich & Rosati. The representatives of Lehman Brothers provided an update on discussions with third parties regarding a possible strategic transaction with the Company and indicated that there were four parties who continued to actively participate in the process. Lehman Brothers also provided the board of directors with a summary of data room activity levels. A representative of Wilson Sonsini Goodrich & Rosati reviewed with the board of directors certain potentially applicable regulatory laws and requirements. Representatives of Wilson Sonsini Goodrich & Rosati also reviewed the terms and conditions of a proposed merger agreement that would be sent to the potentially interested parties. A representative of Lehman Brothers reviewed with the board of directors a proposed bid letter that contained guidelines for submitting a proposal. After discussion, our board of directors authorized the representatives of Lehman Brothers to distribute the bid package, which indicated that proposals were due back on March 25, 2008, to the four active potentially interested parties.

Pursuant to the directive of our board of directors, on March 4, 2008, Lehman Brothers distributed the bid package to the four active potentially interested parties.

In the following weeks, certain of the potentially interested parties and their representatives continued to conduct due diligence on the Company and engage in discussions surrounding a possible business combination transaction involving the Company. Representatives of the Company and Lehman Brothers were actively involved in this process.

On March 25, 2008, the Company received a non-binding proposal from one of the four previously potentially interested parties.

On March 26, 2008, the Executive Committee of our board of directors convened a special meeting to review the non-binding proposal. Also present were representatives of the Company’s management, representatives of Lehman Brothers and Wilson Sonsini Goodrich & Rosati.

On March 30, 2008, our board of directors convened a special meeting to discuss the non-binding proposal through which a strategic buyer would purchase all of the Company’s capital stock in an all-cash transaction at a price of $3.00 per share. Also present at the March 30^th meeting were representatives of Lehman Brothers and Wilson Sonsini Goodrich & Rosati. Lehman Brothers reviewed the process to date, the preliminary indications of interest that had been submitted and the final round bid. The meeting participants then discussed the transaction economics and related matters, the relative stock performance of the Company and the proposed buyer, and our management team’s financial projections for the Company. Wilson Sonsini Goodrich & Rosati summarized the non-price terms of the draft definitive agreement delivered by the proposed buyer, including the expanded closing conditions, expanded representations and warranties, modifications to the definition of “material adverse effect” and the voting agreements. Our board of directors asked questions of Lehman Brothers and of Wilson Sonsini Goodrich & Rosati and, after discussion, determined to reject the proposal, to continue to pursue a stand-alone strategy and, to re-examine the possibility of a possible business combination transaction after a period of at least six months. Notwithstanding this determination, however, the board of directors continued to remain open to the prospect of a business combination transaction because of its concerns regarding the size of the Company and its ability to compete in its markets. Accordingly, the management team was instructed by the board of directors to remain open to overtures from third parties regarding potential strategic transactions.

During the period of time from April to September 2008, our management had informal discussions with several potential strategic partners, but without any resulting proposals for a strategic transaction or business combination.

In August 2008, director Jim Dennedy received a telephone call from a representative of a private equity party regarding a potential acquisition of the Company. Mr. Dennedy subsequently passed the information along to Mr. Conner.

On September 2, 2008, Mr. Conner received a follow-up communication from Robert Sayle of Thoma Bravo to the communication from Mr. Sayle of September 27, 2007 seeking to explore an acquisition of the Company.

On September 11, 2008, the independent members of our board of directors discussed the possibility of exploring a sale of the Company to a private equity firm and, on September 12, 2008, our lead independent director, Mr. Doug Schloss, instructed Mr. Conner to explore a potential sale to a private equity firm, including Thoma Bravo and the other party that had originally communicated with Mr. Dennedy in August 2008.

On September 15, 2008, Lehman Brothers publicly announced that it intended to file a petition under Chapter 11 of the United States Bankruptcy Code. On September 22, 2008, certain assets of Lehman Brothers, including its North American investment banking franchise, were acquired by Barclays Capital Inc. (“Barclays Capital”). As a result, the individuals who had been advising the Company were subsequently hired by Barclays Capital.

On September 17, 2008, members of our management team engaged in communications with a potential strategic buyer regarding a possible strategic transaction or other business combination, but these communications did not result in an indication of interest or offer from the interested party.

During September and October 2008, our management team had initial communications with Thoma Bravo and the additional private equity party regarding a potential acquisition of the Company.

On November 4, 2008, Mr. Sayle of Thoma Bravo delivered a preliminary non-binding indication of interest to acquire the Company in an all cash transaction for $1.75 per share of fully diluted Common Stock of the Company subject to the Company satisfying a minimum cash condition at closing. The proposal indicated that Thoma Bravo intended to finance the acquisition with a combination of equity and debt, with Thoma Bravo funding a significant portion of the equity and no financing contingencies. The proposal further required the Company to agree to a 25 business day exclusivity period from the date of execution of the letter of intent and indicated that the definitive agreement would contain a so-called “go shop” provision allowing the Company to solicit superior proposals for a specified period following the execution of the definitive agreement. In a subsequent communication between Mr. Rockvam of the Company and Mr. Sayles of Thoma Bravo, Mr. Sayles clarified that the definitive agreement would not have a financing contingency, that Thoma Bravo would deliver equity and debt commitment letters at the end of the exclusivity period demonstrating that it has the funds necessary to finance the acquisition and that its lenders could move quickly.

On November 5, 2008, members of the Executive Committee of the board of directors (consisting of directors F. William Conner, Douglas Schloss, Butler Derrick and Jerry Jones) convened a special meeting of the committee to discuss the status of the recent management meetings with Thoma Bravo and the other party. Also present at the meeting were representatives of Barclays Capital and Wilson Sonsini Goodrich & Rosati. The Executive Committee discussed the current business environment, the likelihood of private equity buyers to rely on leverage to finance deals and the attendant risks of debt financing to deal certainty, the status of the two private equity firms, the $1.75 per share valuation provided by Thoma Bravo, the likelihood of an emerging strategic buyer and revenue forecasts for the Company. A representative of Wilson Sonsini Goodrich & Rosati advised the Executive Committee regarding its role and that of the board of directors as a whole in evaluating the Company’s prospects as a stand-alone entity as opposed to pursuing a sale strategy. The Executive Committee determined to have a representative of Barclays Capital contact Thoma Bravo in order to seek additional time to respond to Thoma Bravo’s November 4^th letter to provide the Company’s board of directors with adequate time to properly review the proposal, to clarify that Thoma Bravo would be able to fully fund the proposed transaction in the event no debt financing is available and to inquire whether Thoma Bravo would remove the exclusivity requirement from the letter of intent.

On November 6, 2008, Mr. Conner communicated with the other party and inquired whether that entity was still planning on providing an indication of interest. The other party replied that it has prepared an informal email, which it subsequently provided to Mr. Conner. The informal email indicated that the other party would be

interested in acquiring the Company and its preliminary view that it would pay a premium to the Company’s current stock trading price of $—. Later that day, James D. Kendry, the Vice President and Chief Governance Officer of the Company, sent an email to the board of directors summarizing the two indications of interest.

On November 7, 2008, director Jim Dennedy (who had been designated to the board of directors as the nominee of Empire Capital Partners, L.P.) communicated his desire to be included in any sub-committee evaluating and making decisions regarding a potential transaction.

Based on discussions between representatives of Barclays Capital and Thoma Bravo in which the Barclay’s representative expressed the Company’s desire to have more time to respond to the Thoma Bravo letter of intent, on November 10, 2008, Thoma Bravo provided an updated letter of intent that revised the expiration date of the letter from November 11, 2008 to November 24, 2008.

Pursuant to further discussions between representatives of Barclays Capital and Thoma Bravo, on November 11, 2008, Thoma Bravo provided another update letter of intent clarifying that even though Thoma Bravo anticipates that it will finance a portion of the cash consideration with some level of debt capital, it is willing and prepared to finance the total consideration with equity capital if necessary.

On November 12, 2008, the Company received a written indication of interest from the other party.

On November 18, 2008, Empire Capital Partners, L.P. (“Empire”) filed an amendment to its Schedule 13D with the U.S. Securities and Exchange Commission, pursuant to which it announced that it and certain other investment funds, including Arcadia Capital Advisors, LLC, intended to “maximize the value of their investment” through various means more fully set forth in the Schedule 13D.

On November 19 and 20, 2008, our board of directors held a regularly scheduled meeting at which it discussed, among other matters, next steps with respect to the two preliminary indications of interest. Also attending the meeting were members of the Company management team and representatives of Barclays Capital. Barclays Capital discussed the two preliminary indications of interest with the board of directors. The Thoma Bravo written proposal consisted of all cash consideration of $1.75 per fully diluted share of Common Stock and the competing oral proposal from the other party was reported to be in the range of $1.70 to $1.80 per fully diluted share of Common Stock. The Thoma Bravo proposal indicated that the total consideration could be financed with equity and would not be subject to any financing contingencies. The competing proposal indicated that the equity capital would be funded from current funds under management. The meeting participants then discussed the transaction economics and related matters. The board of directors asked questions and then discussed advantages and disadvantages of the proposed transactions and whether to further explore the transactions. The board of directors further discussed its alternatives, including continuing to operate the business as a stand-alone public entity, a possible combination with other companies, a possible sale to a private company, timing, overall economic conditions, economic outlook for various time periods, the views of large stockholders, various strategies for possible transactions and potential transaction structures and other matters. The board of directors considered whether to contact any other potential bidders, whether private equity firms or other parties, at that time but determined not to do so because it believed that the private equity bidders would exhibit a lower level of commitment if they believed the deal was being further shopped, and also because of the increased possibility of a leak (and potential detrimental effects of a leak) by seeking and holding discussions with multiple third parties, the distraction to management (and the possible negative impact on the Company’s business and operations) by maintaining discussions with multiple third parties, and the expectation that any definitive agreement with Thoma Bravo would contain a “go shop” provision that would enable the Company to solicit alternative acquisition proposals after the definitive agreement was signed and announced. The board of directors also discussed the necessity of deal certainty, acknowledging that the Company could be severely harmed if a deal were announced but not closed and, further to this point, the board of directors discussed several recent failed deals for other corporations and the negative impact that those announced but failed deals had on stockholder value. The board of directors also determined that it should create a special committee to review

strategic alternatives available to the Company, including mergers and acquisitions, and, accordingly, created the “Strategic Planning Committee,” or the Committee, and appointed Jim Dennedy and Jerry Jones as members.

On November 21, 2008, Mr. Conner, the Strategic Planning Committee and representatives of Barclays Capital held a telephone conference to discuss the current proposals. The Committee discussed the timeline for the process and instructed management to direct all further communications with the bidders be channeled through Barclays Capital and Wilson Sonsini Goodrich & Rosati. Following this meeting, Barclays Capital contacted the two bidders and scheduled due diligence sessions and the parties began negotiating confidentiality agreements in order to provide access to the on-line data room with the goal of receiving hard offers on or before December 19, 2008.

On November 24, 2008, pursuant to the direction of our board of directors, the Company entered into an agreement with Empire pursuant to which the Company granted Empire certain board observer rights and additional time for Empire to include a stockholder proposal, under Rule 14a-8 promulgated under the Exchange Act of 1934, as amended, in the Company’s 2009 proxy, Mr. Conner agreed to resign as the chairperson of our board of directors and the Company agreed to take all actions necessary to appoint Michael McGrath as the new chairperson of our board of directors.

On November 25, 2008, at a meeting of our board of directors, the board of directors formally accepted the resignation of Mr. Conner as the chairperson of the board of directors and elected Mr. McGrath as chairperson. Additionally, the board of directors was updated as to the go-forward process adopted by the Strategic Planning Committee.

In response to Thoma Bravo’s indication of interest and in anticipation of future discussions, representatives of Wilson Sonsini Goodrich & Rosati and Barclays Capital, in consultation with the Strategic Planning Committee via email and via telephone conference on November 28, 2008, negotiated a confidentiality agreement with Thoma Bravo, and on November 30, 2008, the Company entered into a confidentiality agreement with Thoma Bravo to enable the parties to share information regarding a potential transaction. The confidentiality agreement expressly prohibits Thoma Bravo from contacting any actual or potential partners or other third parties who would or might provide equity, debt or other financing for a transaction without the Company’s consent except for those entities already agreed to by the Company and listed on an annex to the agreement. The confidentiality agreement also contained an 18-month “standstill” provision which, among other things, prevents Thoma Bravo and its representatives from acquiring the Company’s stock or participating in a proxy solicitation regarding the Company’s stock without the Company’s prior written consent. Barclays Capital then provided Thoma Bravo and its authorized representatives with access to the on-line data room. A similar confidentiality agreement was negotiated with and executed by the other bidder.

During November of 2008, the Company assembled additional non-public information in response to and in anticipation of requests from Thoma Bravo and made this information available to Thoma Bravo through an on-line data room. Throughout the remainder of 2008 and into 2009, the Company continued to supplement this on-line data room with additional non-public information, while also making available to Thoma Bravo certain non-public financial information regarding the Company’s financial condition and results of operations, as well as the Company’s financial budgets, plans and forecasts for future periods, to enable Thoma Bravo to refine its valuation analysis of the Company.

During this same period of time, our management team met with representatives of Thoma Bravo on several occasions to discuss the Company’s business, operations, plans, budgets and forecasts, and to answer questions posed by Thoma Bravo and its advisors regarding these matters, including a meeting on December 2, 2008 with two of Thoma Bravo’s potential financiers, Wells Fargo and Bank of Montreal, a meeting on December 8, 2008 to discuss competitive landscape and market size, and a meeting on December 9, 2008 to discuss specifics concerning the Company’s sales, marketing, services, research and development and financial operations. The Strategic Planning Committee, however, instructed management to refrain from engaging in any discussions with

Thoma Bravo regarding their personal role or involvement in a potential transaction or the surviving company following a transaction until such time as the Strategic Planning Committee authorized them to do so, and management complied with these instructions.

Similarly, during this same period of time, our management team met with representatives of the other bidder to discuss the Company’s business, operations, plans, budgets and forecasts, and to answer questions posed by it and its advisors regarding these matters, including a meeting on December 10, 2008 to provide details regarding the Company’s revenue sources, competitive landscape, cost of revenues, gross margins, operating costs and sales force overview.

As of December 2, 2008 and following his appointment as chairman of our board of directors, Mr. McGrath began to attend meetings and calls of the Strategic Planning Committee, beginning with a Strategic Planning Committee call on December 2, 2008 to discuss the due diligence process, confidentiality agreements and updates on discussions with Thoma Bravo and the other bidder.

On December 5, 2008, the Strategic Planning Committee held a telephone conference in advance of meeting of the board of directors of the same day to discuss the status of the sale process. Later that same day, our board of directors convened a telephonic meeting to discuss the status of the sale process. Also attending were members of our management team, a representative of Wilson Sonsini Goodrich & Rosati and Peter Richards, the board observer appointed by Empire. Mr. Jones, as one of the members of the Strategic Planning Committee, described the status of due diligence and the substance of the proposed draft definitive agreement. The representative from Wilson Sonsini Goodrich & Rosati outlined the directors’ fiduciary duties in connection with their consideration of the preliminary acquisition proposals. The representative from Wilson Sonsini Goodrich & Rosati then described the structure and material terms of the draft definitive agreement to the board of directors, including the scope of the guarantee to provide the Company with a broader right of action in case of default by the acquisition subsidiary, the inclusion of a right to sue for specific performance, the inclusion of a right to seek recovery of any lost premium in the event the transaction does not close, the requirement of the purchaser to provide an equity commitment letter for the entire purchase price, and the inclusion of a “go-shop” provision to allow the Company to seek superior acquisition proposals after signing the definitive agreement. The board of directors approved the draft definitive agreement for distribution to the two bidders and confirmed the authority of the Strategic Planning Committee to negotiate further changes.

Shortly after the December 5^th meeting, Barclays Capital distributed the approved draft of the definitive agreement to the two private equity bidders. During the same time period, our management team continued to meet with representatives of Thoma Bravo to discuss the Company’s business, operations, plans, budgets and forecasts, and to answer questions posed by Thoma Bravo and its advisors regarding these matters. However, at the direction of the Strategic Planning Committee, management continued to refrain from engaging in any discussions with Thoma Bravo regarding their personal role or involvement in a potential transaction or the surviving company.

On December 9, 2008 and December 12, 2008, the Strategic Planning Committee held telephone conferences to discuss the status of the sale process, including updates on the progress of the initial due diligence by Thoma Bravo and the other bidder.

Throughout 2008, the Company has been implementing cost reduction plans, the beneficial financial effects of which had become more evident by the end of 2008. In discussions with management, the Strategic Planning Committee concluded on December 16, 2008 that the cost cutting measures that had commenced in 2008 should be included in the Company’s 2009 financial plan. Accordingly, management updated the 2009 financial plan to reflect the Company’s budgetary modifications and, between December 16, 2008 and December 19, 2008, members of the Strategic Planning Committee, Barclays Capital and our management team communicated with Thoma Bravo regarding the Company’s revised 2009 financial plan.

On December 23, 2008, Thoma Bravo delivered its bid package, including a non-binding letter of intent to acquire Entrust in an all cash transaction for $1.75 per share of Common Stock, together with a draft debt commitment letter on behalf of Wells Fargo Foothill, LLC and Bank of Montreal, who agreed to fund the entire debt financing in order to remove any syndication risk. The proposal indicated that Thoma Bravo intended to finance the acquisition with a combination of equity and debt but would not require a financing contingency in the definitive agreement. The proposal further indicated that there would be a minimum cash amount and required the Company to agree to a ten business day exclusivity period with Thoma Bravo, subject to automatic one week extensions. As part of its bid package, Thoma Bravo included a mark-up of the definitive agreement that Barclays Capital had provided on behalf of the Company. The definitive agreement delivered by Thoma Bravo included a number of changes, including additional closing conditions providing Thoma Bravo with the ability to not close the transaction in the event of a “material adverse effect” upon the Company or failure to obtain certain third party consent, additional termination rights for a Company “material adverse effect” or breach of the “no shop” provision, the elimination of the Company right to seek specific performance, limitations on the Company’s remedies (i.e., $5 million reverse break up fee as sole remedy) in the event of a breach by Merger Sub and its failure to close the proposed transaction, limitations on Thoma Bravo guarantee and no Company rights to enforce the equity or debt commitment letters.

On or about December 24, 2008, the other bidder with whom the Company had been having preliminary discussions contacted the Company to convey that it was no longer interested in exploring a transaction with the Company.

On December 26, 2008, the Strategic Planning Committee discussed the Thoma Bravo bid package with representatives of Barclays Capital and Wilson Sonsini Goodrich & Rosati. Wilson Sonsini Goodrich & Rosati discussed Thoma Bravo’s proposed terms for a transaction and expressed the need to seek significant improvements in certain terms relating to transaction certainty including the Company’s ability to specifically enforce the agreement, the scope of upstream guarantees to be provided by Thoma Bravo, the elimination of or change to the proposed reverse break-up fee, elimination of the additional closing conditions regarding Thoma Bravo’s right to not close the transaction in the event of a “material adverse effect” upon the Company or failure to obtain certain third party consent and Company rights to enforce the equity or debt commitment letters. The meeting participants then discussed the transaction economics and related matters and the Strategic Planning Committee asked questions regarding various matters of Barclays Capital and Wilson Sonsini Goodrich & Rosati. After discussion, the Strategic Planning Committee expressed concern regarding the $1.75 price per share, but determined that the terms of Thoma Bravo’s proposal were sufficient to warrant further discussion in light of the Company’s business and operational challenges, the Company’s long-term strategic goals and alternatives, the Company’s prospects as an independent company and the possibility that the Thoma Bravo proposal could result in a transaction that represented a premium to the Company’s current stock price. On that basis, the Strategic Planning Committee determined to continue negotiations with Thoma Bravo with the goals of seeking a higher price for the Company than that reflected in Thoma Bravo’s preliminary proposal and obtaining deal terms that would provide a high level of certainty of consummating the proposed acquisition. Following the meeting, Mr. Jones provided an email to the complete board of directors to keep it apprised of the latest developments and determinations by the Strategic Planning Committee.

On December 28, 2008, Barclays Capital distributed a list of open material issues from the bid letter and the draft definitive agreement to Thoma Bravo highlighting the Strategic Planning Committee’s continued focus on deal certainty, including the Company’s ability to enforce the financing commitments.

Following the December 26, 2008 Strategic Planning Committee discussion, the Strategic Planning Committee, together with Barclays Capital and Wilson Sonsini Goodrich & Rosati worked to refine the Company’s response to Thoma Bravo’s proposed terms for a transaction and on December 29, 2008, Wilson Sonsini Goodrich & Rosati delivered a written response to Thoma Bravo’s proposed terms for a transaction that, among other things, set forth the material provisions of the definitive agreement that would need to be amended in order to improve transaction certainty, and over the next week Wilson Sonsini Goodrich & Rosati and Kirkland & Ellis LLP discussed the proposed terms for a transaction.

On January 5, 2009, members of our management team held a call to review the Company’s preliminary financial results for the fourth quarter of 2008.

On January 6, 2009, Thoma Bravo provided Barclays Capital with a response to the material issues list and provided an updated letter of intent which would expire if not accepted by January 12, 2009. Thoma Bravo’s written response indicated some flexibility on the deal certainty issues that has been identified as critical by the Company’s board of directors, including providing the Company with the ability to seek specific performance as a remedy.

On January 7, 2009, our board of directors held a special meeting to discuss, among other things, the status of due diligence and to summarize the bid package presented by Thoma Bravo. Also attending the meeting were representatives of Barclays Capital and Wilson Sonsini Goodrich & Rosati. Barclays Capital summarized the status of the sales process. Barclays Capital then summarized its recent negotiations with Thoma Bravo and the terms of the Thoma Bravo bid, including the $1.75 per share all cash consideration, proposed equity commitment to fund the entire consideration and ten day exclusivity period. The meeting participants then discussed the transaction economics and related matters. Mr. Jones then updated the board of directors regarding the discussions that he and other members of the Special Committee have had with Barclays Capital, legal counsel and Thoma Bravo. The board of directors discussed whether Thoma Bravo was likely to increase its price in light of the increase in the price per share of the Company Common Stock, which had closed at $1.70 on the immediately preceding trading day. The representative from Wilson Sonsini Goodrich & Rosati outlined the directors’ duties in connection with their consideration of the preliminary acquisition proposals and then discussed the improvements made by Thoma Bravo to the draft agreement. The board of directors then discussed a number of factors relating to the proposal, including the fact that the current stock price may not be indicative due to its recent volatility, the cash position of the Company, the concerns expressed by large stockholders about operating plan risk, challenges, risks and opportunities attendant to the Company’s stand-alone operating plan, as well as the current state of the markets. After discussion, upon a motion duly made and seconded, the board of directors resolved to reject the price of $1.75 per share and instructed representatives of Barclays Capital to inform Thoma Bravo that $1.75 per share was insufficient consideration and also that the board of directors would only approve a definitive agreement with terms that provided for a high degree of deal certainty.

Between January 7, 2009 and the next meeting of the full board of directors on January 22, 2009, the Strategic Planning Committee had several calls to discuss the process and potential next steps with Thoma Bravo, including calls on January 9, January 10, January 13 and January 21, 2009. Additionally, during January 2009, Mr. Conner contacted a potential strategic partner to discuss its interest, if any, in a possible strategic merger or other business combination transaction with the Company. No proposal resulted from these discussions.

On January 9, 2009, Mr. McGrath communicated with representatives of Thoma Bravo who indicated that the $1.75 price per share was firm and also questioned the Company’s request for greater deal certainty. Mr. McGrath reiterated the Company’s desire for greater deal certainty and a higher price per share.

On January 23, 2009, our board of directors held a regularly scheduled meeting at which it discussed, among other matters, strategic alternatives for the Company. Also attending were representatives of Barclays Capital and Wilson Sonsini Goodrich & Rosati and, for a portion of the meeting, board observer, Peter Richards, appointed on behalf of Empire. The meeting participants then discussed the transaction economics and related matters. Mr. Jones noted that Thoma Bravo had been informed that its bid was rejected and the board of directors discussed various approaches and strategies to encourage Thoma Bravo to raise its bid, including informing it that the process may be opened up to additional parties after announcement of earnings. The board of directors instructed representatives of Barclays Capital to continue discussions with Thoma Bravo and seek to have the price per share in its proposal increased.

On February 2, 2009, the Strategic Planning Committee held a telephone conference to discuss the status of the sale process and emphasized the need of Thoma Bravo to improve its offer.

On February 4, 2009, following earlier discussions between Thoma Bravo and representatives of Barclays Capital, Thoma Bravo delivered an updated draft letter of intent in which it increased the price per share from $1.75 to $1.85 and a letter expiration date of February 6, 2009. Later that day, the Strategic Planning Committee held a telephone conference to discuss the updated offer, which was followed by a special meeting of our board of directors to discuss the status of negotiations with Thoma Bravo and the updated price per share. Representatives of our management team, Barclays Capital and Wilson Sonsini Goodrich & Rosati also attended this meeting. Barclays Capital began the meeting by relaying the message from Thoma Bravo that $1.85 was the highest price per share Thoma Bravo would be willing to pay. Barclays Capital then reviewed the latest Thoma Bravo bid received on February 4, 2009. The meeting participants then discussed the transaction economics and related matters, the board of directors asked questions of Barclays Capital and Wilson Sonsini Goodrich & Rosati, discussed the increased price per share and resolved to move forward with further negotiations at the $1.85 per share price.

On February 6, 2009, the Strategic Planning Committee, representatives of Barclays Capital and our management team discussed the Company’s updated operating plan that reflected the various cost restructuring measures that had been implemented and expected to be implemented, as well as the latest relevant economic, business and financial information concerning the Company and the industry in which it operates.

On February 16, 2009, our board of directors convened a special meeting to review the updated 2009 operating plan for the Company. Mr. Conner explained the framework for the plan and Mr. David Wagner reviewed the content of the plan with the board of directors. After discussion, the board of directors resolved to approve the 2009 operating plan and authorized Company management to provide the plan to Thoma Bravo.

On February 18, 2009, pursuant to the ongoing discussions between representatives of Barclays Capital and Thoma Bravo, Thoma Bravo delivered an updated draft letter of intent reiterating the price per share of $1.85, clarifying that Thoma Bravo was willing to offer specific performance as a remedy, but requiring that the Company reimburse Thoma Bravo in cash for the lesser of half its out of pocket expenses or $250,000 in the event the Company elects not to consummate a transaction with Thoma Bravo. Later that same day and the next day, the Strategic Planning Committee held telephone conference calls to discuss the negotiations with Thoma Bravo regarding the draft letter of intent.

In response to further discussions, Thoma Bravo again updated the draft letter of intent on February 19, 2009 to provide assurances that based on discussions to date, it was confident that the parties could reach final agreement on the terms of a definitive written agreement in a timely fashion. Later that day, our board of directors convened a meeting to discuss the status of negotiations with Thoma Bravo. Representatives of our management team, Barclays Capital and Wilson Sonsini Goodrich & Rosati also attended this meeting. Strategic Planning Committee member Jerry Jones updated the board of directors regarding the status of discussions with Thoma Bravo and summarized the open items on the draft letter of intent, including the minimum cash condition, expense reimbursement terms and restrictions on management employment discussions. The board of directors reviewed these and other matters relating to the letter of intent, including the timing of a possible transaction and the potential impact of announcing a deal on the Company’s customer relationships and forecasted revenues. Barclays Capital then reviewed with the board of directors the latest Thoma Bravo bid received on February 4, 2009. A representative from Wilson Sonsini Goodrich & Rosati next summarized the duties and standards applicable to the board of directors in the context of considering the proposed transaction with Thoma Bravo and also reviewed the process undertaken by the Company to date in evaluating strategic alternatives available to the Company. Mr. Conner then summarized for the board of directors the risks of continuing as a public stand-alone entity, including the competitive risks and costs and the risk associated with the two largest vertical markets of financial services and government. The meeting participants then discussed the transaction economics and related matters and the board of directors asked questions regarding various matters of Barclays Capital and Wilson

Sonsini Goodrich & Rosati. The board of directors then discussed a variety of factors relating to the proposed transaction including:

After discussion, our board of directors approved the draft letter of intent with Thoma Bravo, added director Michael McGrath to the Strategic Planning Committee and authorized the Strategic Planning Committee to execute the draft letter of intent with Thoma Bravo and to negotiate the definitive agreement.

On February 20, 2009, Strategic Planning Committee member Jerry Jones executed the letter of intent on behalf of the Company. The terms of the executed letter of intent included an exclusivity period of 10 business days, consideration of $1.85 per share of fully diluted Company Common Stock, a minimum cash condition and a maximum of $100,000 expense reimbursement provision.

During the following weeks, members of the Strategic Planning Committee met with management on numerous occasions, including on February 26, February 27, March 2, March 4 and March 6 to receive updates on the due diligence process and coordinated with legal counsel and Thoma Bravo to coordinate progress on the draft definitive agreement. Additionally, Kirkland & Ellis provided additional requests for due diligence and the Company continued to add material to the on-line data room.

On February 26, 2009, representatives of Kirkland & Ellis delivered a revised draft of the definitive agreement to Wilson Sonsini Goodrich & Rosati. The definitive agreement delivered by Kirkland & Ellis included a number of changes from the original draft circulated on behalf of the Company, including additional closing conditions providing Thoma Bravo with the ability to not close the transaction in the event of a “material adverse effect” upon the Company or failure to obtain certain third party consent, additional termination rights for a Company “material adverse effect” or breach of the “no shop” provision, limitations on the Company’s remedies (i.e., $5 million reverse break up fee as sole remedy) in the event of a breach by Merger Sub and its failure to close the proposed transaction, limitations on the Thoma Bravo guarantee and no Company rights to enforce the equity or debt commitment letters.

Over the next several weeks, Thoma Bravo continued its due diligence and legal counsel continued to address outstanding legal issues in the draft definitive agreement. Company management continued to meet with Thoma Bravo and its advisors to discuss due diligence issues but continued, at the direction of the Strategic Planning Committee, to refrain from any discussions regarding management compensation. However, in early March 2009, Thoma Bravo communicated to the Strategic Planning Committee that it viewed the risks associated with buying a company without management in place to be unacceptable, and therefore it would not move forward with a definitive agreement unless it had the opportunity to assure itself that Company management were committed to remaining with the Company after the closing of the proposed transaction. Accordingly, on March 2, 2009, the Strategic Planning Committee held a call with representatives of Barclays Capital and Wilson Sonsini Goodrich & Rosati to discuss both the latest draft of the definitive agreement and the scope of permissible communications between Thoma Bravo and Company management regarding management compensation.

On March 3, 2009, Thoma Bravo provided a summary of its general compensation philosophy to the Strategic Planning Committee, which the Strategic Planning Committee discussed with Wilson Sonsini Goodrich & Rosati and Barclays Capital. The Strategic Planning Committee then authorized Mr. Conner and Mr. Kendry to have a call with Thoma Bravo regarding its general compensation philosophy, provided that a representative of Wilson Sonsini Goodrich & Rosati would be present and that Thoma Bravo would not engage in discussions regarding specific terms of employment for Company management. Following the conference call between Thoma Bravo and Mesrrs. Conner and Kendry, Thoma Bravo advised the Strategic Planning Committee that it desired to provide written term sheets setting forth specific compensation information for members of the management team.

In early March 2009, Thoma Bravo continued its due diligence sessions with Company management and Kirkland & Ellis continued its legal due diligence review of the Company. On March 6, 2009, the Strategic Planning Committee determined to grant Thoma Bravo an extension of the exclusivity period by an additional 10 business days through March 20, 2009.

Over the course of the next 10 business days, the Strategic Planning Committee held several calls, including calls on March 10, March 11 and March 19, 2009, to discuss the status of the definitive agreement and Thoma Bravo’s request that it would not move ahead with the proposed transaction unless it were permitted to put in place more formal arrangements with Company management, including signed term sheets. With the exclusivity period expiring again on March 20, 2009, the Strategic Planning Committee held a call on March 19, 2009 and determined that Jerry Jones should act as the Company’s representative to directly engage with Thoma Bravo in order to negotiate open issues in the definitive agreement. Furthermore, in light of Thoma Bravo’s expressly stated reluctance to move forward with the proposed transaction without further direct communications with Company management regarding specific employment terms, the Strategic Planning Committee determined that Thoma Bravo could speak directly with Company management regarding specific future employment terms, but must provide any term sheets in advance to the Strategic Planning Committee and must conclude its discussions with Company management expeditiously.

On March 25, 2009, the Strategic Planning Committee determined that it would deliver a message to Thoma Bravo that Thoma Bravo had until 5p.m. PT on Friday, March 27, 2009 to make significant progress with Company management and to resolve certain material issues in the definitive agreement in order to continue further discussions. The Strategic Planning Committee then communicated to the board of directors the status of negotiations and the message intended to be communicated to Thoma Bravo, to which message the Committee received general supportive feedback from various members of our board of directors.

On March 26, 2009, on behalf of Thoma Bravo, Kirkland & Ellis delivered a revised draft of the definitive agreement to Wilson Sonsini Goodrich & Rosati. The draft agreement deleted certain carve outs regarding adverse effects caused by the announcement and pendency of the proposed transaction from the definition of Material Adverse Effect, made significant limiting revisions to the definition of “Minimum Closing Cash,” and

limited the Company’s proposals regarding deal certainty including its rights to seek specific enforcement. Thoma Bravo also delivered a letter requesting an additional period of exclusivity, but the letter was not executed.

On March 27, 2009, the Strategic Planning Committee received feedback of significant progress (from both Company management and legal counsel) on both discussions with management and on the draft definitive agreement with Thoma Bravo.

Between March 29, 2009 and April 12, 2009, Wilson Sonsini Goodrich & Rosati and Kirkland & Ellis exchanged drafts of the definitive agreement and the equity commitment letter, with significant progress beginning to be made during the week of April 3, 2009 in terms of narrowing the open issues.

On April 2, 2009, the Company and Thoma Bravo agreed to amend the confidentiality agreement in order to make the agreement mutual and allow the Company to conduct due diligence on the Thoma Bravo funds.

Throughout the weekend of April 4 and April 5 and over the week beginning on April 6, 2009, Barclays Capital and Wilson Sonsini Goodrich & Rosati, in frequent consultation with Mr. Jones of the Strategic Planning Committee, engaged in discussions with Thoma Bravo and Kirkland & Ellis in an effort to improve the non-price terms of the proposed transaction with Thoma Bravo. Drafts of the definitive transaction documents were circulated back and forth and on April 9, 2009, the Strategic Planning Committee convened a meeting to receive an update on the progress that had been made. Representatives from Barclays Capital and Wilson Sonsini Goodrich & Rosati attended the meeting. Wilson Sonsini Goodrich & Rosati began with an update regarding the proposed non-price terms of a transaction, and reported that Thoma Bravo’s legal advisors had tentatively agreed upon the material non-price terms of the proposed transaction, subject to the Strategic Planning Committee’s approval, other than certain representations and warranties in the Agreement. Barclays Capital then reported that it expected to be in a position to deliver a fairness opinion at the meeting of the board of directors to be convened later that afternoon. The Strategic Planning Committee members and a representative of Wilson Sonsini Goodrich & Rosati then summarized the material terms and conditions relating to the definitive agreement, including deal certainty terms, timing and the required stockholder vote. After discussion, the Strategic Planning Committee unanimously determined to recommend to the board of directors the terms and conditions of the definitive agreement, subject to the board of directors’ determination to approve the proposed merger.

Later that same day, our board of directors convened a meeting to consider the proposed transaction. Representatives from Barclays Capital and Wilson Sonsini Goodrich & Rosati attended the meeting, as well as Mr. Richards, the board observer from Empire Capital. After some administrative matters, Mr. Jones summarized the process and actions undertaken by the Strategic Planning Committee in its evaluation and negotiation of the proposed transaction. Thereafter, representatives from Barclays Capital reviewed Barclays Capital’s financial analysis of the proposed transaction and the go-shop process, and reported on the diligence review it had conducted on Newco. After discussion, a representative from Barclays Capital rendered Barclays Capital’s oral opinion (which was subsequently confirmed in writing) that, as of April 9, 2009 and based upon and subject to the qualifications, limitations and assumptions stated in its written opinion, from a financial point of view, the consideration to be offered to the stockholders of the Company in the proposed merger was fair to the stockholders. The observer from Empire Capital stated Empire’s support for the proposed merger and then he and the representatives from Barclays Capital left the meeting. Next, a representative of Wilson Sonsini Goodrich & Rosati reviewed the duties applicable to the board of directors in the context of the proposed transaction. After discussion of a variety of factors relating to the proposed merger, including the Company’s prospects, the terms of the definitive agreement, regulatory matters relating to the proposed merger and the impact of having less than unanimous board approval, the board of directors directed the Strategic Planning Committee and Wilson Sonsini Goodrich & Rosati to finalize any remaining open issues in the definitive agreement or otherwise relating to the proposed merger.

Following the April 9, 2009 meeting of the Special Committee, Wilson Sonsini Goodrich & Rosati continued discussions with Kirkland & Ellis to resolve the remaining issues that had not been agreed upon, including certain representations and warranties in the agreement and the requisite board vote required by Thoma Bravo.

On April 10, 2009, Mr. Jones of the Strategic Planning Committee communicated with Thoma Bravo and confirmed that Thoma Bravo would be willing to proceed with the transaction if approved by a majority of the Company’s board of directors.

Further to Mr. Jones’ discussion with Thoma Bravo, on April 11, 2009, Wilson Sonsini Goodrich & Rosati distributed a revised draft of the definitive agreement to Kirkland & Ellis.

On April 11, 2009, our board of directors convened a meeting to consider the proposed transaction. Representatives from Wilson Sonsini Goodrich & Rosati attended the meeting. Mr. Ringler reported that the respective legal advisors had closed all of the remaining material issues and that the definitive agreements for a transaction with Thoma Bravo had been fully negotiated and were ready for execution if and when the board of directors chose to proceed, subject to finalizing certain disclosure schedules and representations and warranties. Wilson Sonsini Goodrich & Rosati then described the terms and conditions of the definitive agreements for the proposed transaction with Thoma Bravo, including the equity commitment letters and guarantees from the equity participants and the debt commitment letters for the debt financing sources. After discussion of a variety of factors relating to the Merger, the board of directors approved the execution, delivery and performance of the Merger Agreement and the consummation of the Merger, with F. William Conner abstaining (in order to avoid any appearance of a conflict of interest resulting from his employment arrangements with Thoma Bravo) and Douglas Schloss voting against the Merger.

On April 12, 2009, on behalf of Thoma Bravo, Kirkland & Ellis delivered a revised draft of the definitive agreement for the proposed transaction to Wilson Sonsini Goodrich & Rosati, which reflected the material terms upon which the parties had earlier reached tentative agreement. Accordingly, representatives of Wilson Sonsini Goodrich & Rosati confirmed this draft of the definitive agreement as acceptable to the Company. Later that same day, the Company and Thoma Bravo executed the final merger agreement. Also on that day, Messrs. Conner, Kendry and Wagner each entered into letter agreements with Thoma Bravo regarding the terms of their respective employment following completion of the proposed transaction.

On April 13, 2009, the parties issued a press release announcing execution of the definitive merger agreement.

Reasons for the Merger; Strategic Planning Committee; Recommendation of Our Board of Directors

The Strategic Planning Committee, consisting solely of independent directors, and, acting with the advice and assistance of the Company’s independent legal and financial advisors, evaluated and actively participated in the negotiation of the Merger, including the terms and conditions of the Merger Agreement with Newco and Merger Sub. At the meeting held on April 9, 2009 described above, the Strategic Planning Committee unanimously recommended the terms of the Merger Agreement to the board of directors.

Our board of directors, at the meeting held on April 11, 2009 described above, (i) determined that the Merger is in the best interests of the Company and its stockholders, and declared it advisable to enter into the Merger Agreement and effect the Merger, (ii) approved the execution, delivery and performance of the Merger Agreement and the consummation of the transactions contemplated thereby, including the Merger, (iii) resolved to recommend that the stockholders approve the adoption of the Merger Agreement and directed that such matter

be submitted for consideration of the stockholders of the Company at the stockholders meeting and (iv) took all necessary actions so that, to the extent permitted by law, the provisions of Section 3-601 et. Seq. of the MGCL and any other similar applicable “anti-takeover” law will not be applicable to the Merger.

In the course of reaching its determination, our board of directors considered the following factors and potential benefits of the Merger:

Our board of directors also considered a variety of risks and other potentially negative factors concerning the Merger Agreement and the Merger, including the following:

The foregoing discussion summarizes the material factors considered by the board of directors in its consideration of the Merger. After considering these factors, the board of directors concluded that the positive factors relating to the Merger Agreement and the Merger outweighed the potential negative factors. In view of the wide variety of factors considered by the board of directors, and the complexity of these matters, the board of directors did not find it practicable to quantify or otherwise assign relative weights to the foregoing factors. In addition, individual members of the board of directors may have assigned different weights to various factors. The board of directors approved and recommends the Merger Agreement and the Merger based upon the totality of the information presented to and considered by it.

Our board of directors recommends that you vote “FOR” the approval of the Merger and “FOR” the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies.

The Company engaged Barclays Capital to act as its financial advisor with respect to pursuing strategic alternatives for the Company, including a possible sale of the Company. On April 9, 2009, Barclays Capital rendered its oral opinion (which was subsequently confirmed in writing on April 12, 2009) to the Company’s board of directors that, as of such date and based upon and subject to the qualifications, limitations and assumptions stated in its opinion, from a financial point of view, the Merger Consideration of $1.85 per share to be offered to the stockholders of the Company in the Merger was fair to such stockholders. April 9, 2009 was the last trading day before Barclays Capital delivered its written opinion.

The full text of Barclays Capital’s written opinion, dated as of April 12, 2009, is attached as Annex B to this Proxy Statement. Barclays Capital’s written opinion sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Barclays Capital in rendering its opinion. You are encouraged to read the opinion carefully in its entirety. The following is a summary of Barclays Capital’s opinion and the methodology that Barclays Capital used to render its opinion. This summary is qualified in its entirety by reference to the full text of the opinion.

Barclays Capital’s opinion, the issuance of which was approved by Barclays Capital’s Fairness Opinion Committee, is addressed to the board of directors of the Company, addresses only the fairness, from a financial point of view, of the consideration to be offered to the stockholders of the Company in the Merger and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Merger or any other matter. The terms of the Merger were determined through arm’s-length negotiations between the Company and HAC Holdings, Inc. and were approved by the Company’s board of directors. Barclays Capital did not recommend any specific form of consideration to the Company or that any specific form of consideration constituted the only appropriate consideration for the Merger. Barclays Capital was not requested to opine as to, and its opinion does not in any manner address, the Company’s underlying business decision to proceed with or effect the proposed transaction. In addition, Barclays Capital expressed no opinion on, and its opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the consideration to be offered to the stockholders of the Company in the Merger. No limitations were imposed by the Company’s board of directors upon Barclays Capital with respect to the investigations made or procedures followed by it in rendering its opinion.

In arriving at its opinion, Barclays Capital assumed and relied upon the accuracy and completeness of the financial and other information used by Barclays Capital without any independent verification of such information and further relied upon the assurances of management of the Company that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Management Projections, upon the advice of the Company, Barclays Capital assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and that the Company would perform substantially in accordance with such projections. In addition, for the purposes of Barclays Capital’s analysis and with the Company’s consent, Barclays Capital also relied on the Street Estimates. The Company agreed with the appropriateness of the use of, and Barclays Capital’s reliance upon, such Street Estimates in performing its analysis. Barclays Capital assumed no responsibility for and expressed no view as to any such projections or estimates or the assumptions on which they were based. In arriving at its opinion, Barclays Capital did not conduct a physical inspection of the properties and facilities of the Company and did not make or obtain any evaluations or appraisals of the assets or liabilities of the Company. In addition, prior to delivery of its written opinion Barclays Capital was not authorized by the Company to solicit, and did not solicit, any indications of interest from any third party with respect to the purchase of all or a part of the Company’s business. Barclays Capital’s opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, April 12, 2009. Barclays Capital assumed no responsibility for updating or revising its opinion based on events or circumstances that may have occurred after, April 12, 2009.

Barclays Capital assumed the accuracy of the representations and warranties contained in the merger agreement and all agreements related thereto. Barclays Capital also assumed, upon the advice of the Company, that all material governmental, regulatory and third party approvals, consents and releases for the proposed

transaction would be obtained within the constraints contemplated by the merger agreement and that the proposed transaction would be consummated in accordance with the terms of the merger agreement without waiver, modification or amendment of any term, condition or agreement thereof that would be material to Barclays Capital’s analyses. Barclays Capital did not express any opinion as to any tax or other consequences that might result from the proposed transaction, nor did its opinion address any legal, tax, regulatory or accounting matters, as to which Barclays Capital understood that the Company obtained such advice as it deemed necessary from qualified professionals.

In connection with rendering its opinion, Barclays Capital performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, Barclays Capital did not ascribe a specific range of values to the shares of the Company Common Stock but rather made its determination as to fairness, from a financial point of view, to the Company’s stockholders of the consideration to be offered to such stockholders in the Merger on the basis of various financial and comparative analyses. The preparation of a fairness opinion is a complex process and involves various determinations as to the most appropriate and relevant methods of financial and comparative analyses and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to summary description.

In arriving at its opinion, Barclays Capital did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor relative to all other analyses and factors performed and considered by it and in the context of the circumstances of the particular transaction. Accordingly, Barclays Capital believes that its analyses must be considered as a whole, as considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion.

The following is a summary of the material financial analyses used by Barclays Capital in preparing its opinion to the Company’s board of directors. Certain financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by Barclays Capital, the tables must be read together with the text of each summary, as the tables alone do not constitute a complete description of the financial analyses. In performing its analyses, Barclays Capital made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of the Company or any other parties to the Merger. None of the Company, HAC Holdings, Inc., HAC Acquisition Corporation, Barclays Capital, their respective affiliates or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of the businesses do not purport to be appraisals or reflect the prices at which the businesses may actually be sold.

In order to assess how the public market values shares of similar publicly traded companies, Barclays Capital reviewed and compared specific financial and operating data relating to the Company with selected companies that Barclays Capital, based on its experience in the security software industry, deemed comparable to the Company. The selected comparable companies were:

Barclays Capital calculated and compared various financial multiples and ratios of the Company and the selected comparable companies. As part of its selected comparable company analysis, Barclays Capital calculated and analyzed each company’s ratio of:

The enterprise value of each company was obtained by adding its short and long-term debt to the sum of the market value of its common equity, the value of any preferred stock (at liquidation value) and the book value of any minority interest, and subtracting its cash and cash equivalents. All of these calculations were performed, and based on publicly available financial data (including Wall Street research) and closing prices, as of April 6, 2009. The results of this selected comparable company analysis are summarized below:

Barclays Capital selected the comparable companies listed above because their businesses and operating profiles are reasonably similar to that of the Company. However, because of the inherent differences between the business, operations and prospects of the Company and those of the selected comparable companies, Barclays Capital believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, Barclays Capital also made qualitative judgments concerning differences between the business, financial and operating characteristics and prospects of the Company and the selected comparable companies that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between the Company and the companies included in the selected company analysis. Based upon these judgments, Barclays Capital selected a range of stock price/CY2009E cash EPS multiples of 10.0x to 13.0x and a range of stock price/CY2010E cash EPS multiples of 9.0x to 13.0x. Barclays Capital then applied such multiple ranges to the Company’s calendar year 2009 and calendar year 2010 estimated cash EPS, respectively, based on both

Management Projections and Street Estimates to calculate ranges of implied prices per share of the Company. The following summarizes the results of these calculations:

Barclays Capital noted that the Merger Consideration of $1.85 per share was within each range of implied values per share calculated using both Management Projections and Street Estimates, except that the Merger Consideration of $1.85 per share was below the range calculated using 2009 calendar year estimated cash EPS based on Management Projections.

Additionally, based upon the same qualitative judgments described above, Barclays Capital selected a range of enterprise value/CY2009E revenue multiples of 0.60x to 1.50x and a range of enterprise values/CY2010E revenue multiples of 0.50x to 1.40x. Barclays Capital then applied such multiple ranges to the Company’s calendar year 2009 and calendar year 2010 estimated revenue, respectively, based on both Management Projections and Street Estimates to calculate ranges of implied prices per share of the Company. The following summarizes the results of these calculations:

Barclays Capital noted that the Merger Consideration of $1.85 per share was within each range of implied values per share calculated using both Management Projections and Street Estimates.

In order to estimate the present value of the Company Common Stock, Barclays Capital performed a discounted cash flow analysis of the Company. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the “present value” of estimated future cash flows of the asset. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors.

To calculate the estimated enterprise value of the Company using the discounted cash flow method, Barclays Capital added (1) the Company’s projected after-tax unlevered free cash flows for fiscal years 2009 through 2013 based on both Management Projections and Street Estimates to (2) the “terminal value” of the Company as of December 31, 2013 based on both Management Projections and Street Estimates, and discounted such amount to its present value (as of April 6, 2009) using a range of selected discount rates. The after-tax unlevered free cash flows based on each of the Management Projections and Street Estimates were calculated by taking the tax-affected earnings before interest and tax expense (excluding amortization of purchased intangibles and including stock based compensation), adding depreciation and amortization and subtracting capital expenditures, and a restructuring charge related to a $16.4 million outstanding lease obligation (excluding any potential sublet recoveries per management) and adjusting for changes in working capital. The residual value of

the Company at the end of the forecast period, or “terminal value,” was estimated by selecting a range of terminal value multiples based on forward 12-month EBITDA of 5.0x to 8.0x and applying such range to EBITDA projections for the fiscal year ending 2014 based on both the Management Projections and Street Estimates. The range of discount rates of 13.0% to 17.0% was selected based on an analysis of the weighted average cost of capital of the Company. Barclays Capital then calculated a range of implied prices per share of the Company. The following summarizes the results of these calculations:

Barclays Capital noted that the Merger Consideration of $1.85 per share was within the ranges of implied values per share calculated using both Management Projections and Street Estimates.

Barclays Capital reviewed and compared the purchase prices and financial multiples paid in selected other transactions that Barclays Capital, based on its experience with merger and acquisition transactions, deemed relevant. As part of its selected precedent transaction analysis, Barclays Capital calculated and analyzed each target company’s:

Barclays Capital chose precedent transactions based on, among other things, the similarity of the applicable target companies in the transactions to the Company with respect to the size, mix, margins and other characteristics of their businesses. Barclays Capital reviewed the following transactions:

The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences in the business, operations, financial conditions and prospects of the Company and the companies included in the selected precedent transaction analysis. Accordingly, Barclays Capital believed that a purely quantitative selected precedent transaction analysis would not be particularly meaningful in the context of considering the Merger. Barclays Capital therefore made qualitative judgments concerning differences between the characteristics of the selected precedent transactions and the Merger which would affect the acquisition values of the selected target companies and the Company. The following table sets forth the results of such analysis:

Based upon the qualitative judgments described above and the TEV/forward revenue multiples (unadjusted) for the precedent transactions set forth above, Barclays Capital selected a range of TEV/forward revenue multiples of 1.00x to 3.00x and applied such range to the Company’s calendar year 2009 estimated revenue based on both Management Projections and Street Estimates to calculate ranges of implied prices per share of the Company. The following table sets forth the results of such calculations:

Barclays Capital noted that the Merger Consideration of $1.85 per share was within the ranges of implied values per share calculated using both Management Projections and Street Estimates.

Additionally, based upon the same qualitative judgments described above and the TEV/forward revenue multiples (NASDAQ adjusted) for the precedent transactions set forth above, Barclays Capital selected a range of TEV/forward revenue multiples of 0.60x to 2.00x and applied such range to the Company’s calendar year 2009 estimated revenue based on both Management Projections and Street Estimates to calculate ranges of implied prices per share of the Company. The following table sets forth the results of such calculations:

Barclays Capital noted that the Merger Consideration of $1.85 per share was within the ranges of implied values per share calculated using both Management Projections and Street Estimates.

In order to assess the premium offered to the stockholders of the Company in the Merger relative to the premiums offered to stockholders in other transactions, Barclays Capital reviewed the premium paid in the all domestic technology transactions of companies valued between $100 million and $500 million from January 1, 2004 to April 6, 2009. For each transaction, Barclays Capital calculated the premium per share paid by the acquirer by comparing the announced transaction value per share to the target company’s historical average closing share price during the following periods: (i) the one trading day prior to announcement, (ii) 30 calendar

days prior to announcement, (iii) 60 calendar days prior to announcement, and (iv) 90 calendar days prior to announcement. The results of this transaction premium analysis are summarized below:

The reasons for and the circumstances surrounding each of the transactions analyzed in the transaction premium analysis were diverse and there are inherent differences in the business, operations, financial conditions and prospects of the Company and the companies included in the transaction premium analysis. Accordingly, Barclays Capital believed that a purely quantitative transaction premium analysis would not be particularly meaningful in the context of considering the Merger. Barclays Capital therefore made qualitative judgments concerning the differences between the characteristics of the selected transactions and the Merger which would affect the acquisition values of the target companies and the Company. Based upon these judgments and using the 1st and 3rd quartile premium to stock price, Barclays Capital selected a range of 10.0% to 50.0% for 1 day premiums paid, and 20.0% to 45.0% for 30, 60 and 90-calendar days premiums paid. Barclays Capital then applied the corresponding historical average price of the Company common stock as of April 6, 2009 to each of these ranges to calculate a range of implied prices per share of the Company. The following summarizes the results of these calculations:

Barclays Capital noted that on the basis of the transaction premium analysis, the Merger Consideration of $1.85 per share was within the ranges of implied values per share calculated.

To illustrate the trend in the historical trading prices of the Company Common Stock, Barclays Capital considered historical data with regard to the trading prices of the Company Common Stock. In particular, Barclays Capital noted that for the 52-week period from April 7, 2008 to April 6, 2009 the closing price of the Company Common Stock ranged from $1.01 to $3.37 per share and that the Merger Consideration of $1.85 per share was within such range.

In order to illustrate how the Merger Consideration compared with publicly available price targets Barclays Capital evaluated published equity research analysts’ projected 12-month price targets for the Company Common Stock. Based on the foregoing, Barclays Capital then calculated a range of the present values of the 12-month price targets of $1.48 to $3.65 using a discount rate of 15% and noted that the Merger Consideration of $1.85 per share was within such range.

Barclays Capital is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. The Company’s board of directors selected Barclays Capital because of its

familiarity with the Company and its qualifications, reputation and experience in the valuation of businesses and securities in connection with mergers and acquisitions generally, as well as substantial experience in transactions comparable to the Merger.

Barclays Capital is acting as financial advisor to the Company in connection with the proposed transaction. As compensation for its services in connection with the proposed transaction, the Company paid Barclays Capital a fee of $750,000 upon the delivery of Barclays Capital’s opinion. Upon completion of the Merger a fee of $2,500,000 will be payable against which the amounts paid for the opinion will be credited. In addition, the Company has agreed to reimburse Barclays Capital for its reasonable out-of-pocket expenses incurred in connection with the engagement and to indemnify Barclays Capital for certain liabilities that may arise out of its engagement by the Company and the rendering of Barclays Capital’s opinion. Barclays Capital may perform from time to time various investment banking and financial services for the Company and affiliates (including portfolio companies) of Thoma Bravo and expects to receive customary fees for such services.

In the ordinary course of its business, Barclays Capital actively trades in the equity securities (and any derivatives thereof) of the Company 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 (and any derivatives thereof).

In considering the recommendations of the board of directors, Entrust’s stockholders should be aware that certain of Entrust’s directors and executive officers have interests in the transaction that are different from, or in addition to, the interests of Entrust’s stockholders generally. These interests may present them with actual or potential conflicts of interest, and these interests, to the extent material, are described below. The board of directors was aware of these potential conflicts of interest and considered them, among other matters, in reaching its decisions to approve the Merger Agreement and the Merger and the recommendation that our stockholders vote in favor of approving the Merger.

As of the record date, there were approximately — shares of the Company’s Common Stock issuable pursuant to stock options granted under our equity incentive plans to our current executive officers and directors. Upon the consummation of the Merger, each then outstanding Company option, including unvested Company options, will be cancelled, and exchanged (A) in the case of any Company option that is vested in accordance with the terms of the applicable Company Stock Plan and has a per share exercise price less than $1.85, for the right to receive from the Surviving Corporation for each share of the Company’s Common Stock subject to such Company option immediately prior to the consummation of the Merger, an amount (subject to any applicable withholding tax) in cash equal to the product of (x) the number of shares of the Company’s Common Stock subject to such Company option immediately prior to the consummation of the Merger and (y) the amount by which $1.85 exceeds the per share exercise price of such Company option, or (B) in the case of any Company option having a per share exercise price equal to or greater than $1.85 or any unvested Company option, without the payment of cash or issuance of other securities in respect thereof. Newco will, or will cause the Company to, pay to holders of eligible Company options the option consideration described above, without interest thereon, less applicable taxes required to be withheld with respect to these payments.

Our directors and executive officers hold an aggregate of approximately — shares of the Company’s Common Stock issuable pursuant to stock options granted under our equity incentive plans as of —, 2009. All of these options have exercise prices greater than $1.85 per share and, accordingly, our directors and executive officers will receive no consideration in respect of these stock options as a result of the completion of the Merger.

As of the record date, there were approximately — Company stock-based awards (including approximately 207,264 restricted stock units, — performance share units and — restricted stock units) granted under our equity incentive plans to our current executive officers and directors. Upon the consummation of the Merger, each Company stock-based award that is outstanding, whether or not then vested, will become fully vested and will be converted automatically into the right to receive upon the consummation of the Merger an amount in cash in U.S. dollars equal to the product of (x) the total number of shares of the Company’s Common Stock subject to such Company stock-based award and (y) $1.85 (reduced, if applicable, by any exercise or base price applicable to the relevant Company stock-based award) and each Company stock-based award will be cancelled and will only entitle the holder to payment described above.

None of the stock appreciation rights have exercise or base prices less than $1.85 and, accordingly, our directors and executive officers will receive no consideration in respect of these Company stock-based awards as a result of the completion of the Merger. The following tables identify, for each of our directors and executive officers, the aggregate number of shares of our Common Stock subject to outstanding Company stock-based awards as of —, 2009 and the value of such Company stock-based awards that will become fully vested in connection with the Merger. The information in the table assumes that all such Company stock-based awards remain outstanding on the closing date of the Merger.

As of the date of this proxy statement, aside from the executive side letters noted below, we have not entered into any employment agreements with our management in connection with the Merger, nor amended or modified any existing employment agreements. Newco has informed us that it currently intends to retain members of our management team following the Merger, and that it anticipates that F. William Conner, our chief executive officer, will continue as chief executive officer. Prior to execution of the Merger Agreement and as

described above in “Background to the Merger,” Messrs. Conner, Wagner and Kendry had discussions with Newco regarding terms of employment following the Merger. Newco has informed us that it intends to establish equity-based incentive compensation plans for management of the Surviving Corporation, a substantial portion of which is likely to be allocated to key employees. The size of such equity based incentive compensation plans has not yet been determined and no awards have been made or promised. We understand that equity awards granted under these incentive compensation plans would generally vest over four years of continued employment and would entitle the recipients of the awards to share in the future appreciation of the Surviving Corporation.

Although it is likely that certain members of our management team will enter into new arrangements with Newco or its affiliates regarding employment (and severance arrangements) with, and the right to purchase or participate in the equity of, Newco (and/or a subsidiary thereof), there can be no assurance that the parties will reach agreement. These matters are subject to further negotiations and discussion and no terms or conditions have been finalized other than those described below. Entrust’s board of directors previously authorized reimbursement of management’s reasonable out-of-pocket legal expenses in connection with negotiating management’s arrangements with Newco and the Surviving Corporation.

Mr. Conner has entered into an executive side letter, which provides, in part, that subject to the consummation of the transactions contemplated by the Merger Agreement, Mr. Conner will enter into definitive agreements with Newco, pursuant to which his Severance and Change in Control Agreement, dated February 2, 2004 (which could potentially entitle Mr. Conner to receive cash payments and other benefits valued in excess of $3,000,000 following the consummation of the proposed Merger, as described in greater detail below), will be terminated in exchange for:

In addition to the terms noted in Mr. Conner’s side letter, the following is a summary of Mr. Conner’s employment terms:

Mr. Wagner has entered into an executive side letter, which provides, in part, that subject to the consummation of the transactions contemplated by the Merger Agreement, Mr. Wagner will enter into definitive agreements with Newco, pursuant to which his Severance and Change in Control Agreement, dated February 2, 2004 (which could potentially entitle Mr. Wagner to receive cash payments and other benefits valued in excess of $993,750 following the consummation of the proposed Merger, as described in greater detail below), will be terminated in exchange for:

In addition to the terms noted in Mr. Wagner’s side letter, the following is a summary of Mr. Wagner’s employment terms:

Mr. Kendry has entered into an executive side letter, which provides, in part, that subject to the consummation of the transactions contemplated by the Merger Agreement, Mr. Kendry will enter into definitive agreements with Newco, pursuant to which his Severance and Change in Control Agreement, dated February 2, 2004 (which could potentially entitle Mr. Kendry to receive cash payments and other benefits valued in excess of $937,500 following the consummation of the proposed Merger), will be terminated in exchange for:

In addition to the terms noted in Mr. Kendry’s side letter, the following is a summary of Mr. Kendry’s employment terms:

Each of our current executive officers have certain change in control and/or severance arrangements as described below.

The Surviving Corporation has agreed to indemnify, to the greatest extent permitted by law, each of our present and former officers, directors and employees against all expenses, losses and liabilities (and to comply with all of our obligations to advance funds for expenses) incurred in connection with any claim, action, suit proceeding or investigation arising out of, relating to, or in connection with, any act or omission in their capacity as an officer, director or employee occurring on or before the consummation of the Merger.

The Merger Agreement requires that we purchase, and that following the consummation of the Merger, the Surviving Corporation maintain, “tail coverage” directors’ and officers’ liability insurance policies containing the same coverage and in the same amount as the Company’s existing policies and with a claims period of at least six years from the consummation of the Merger for claims arising from facts or events that occurred on or prior to the consummation of the Merger.

To the extent that any of our executive officers remain employed by the Surviving Corporation, they will be entitled to receive compensation and benefits following the Merger. For a period of six months following the consummation of the Merger, the Surviving Corporation shall either:

All of the Company’s executive officers currently participate or are eligible to participate in the Company’s benefit plans, which include medical, dental, vision, prescription drug, life insurance, accidental death and dismemberment insurance, short term and long term disability, employee assistance program, flexible spending accounts, adoption assistance, long-term care insurance, 401(k) Plan, bonus plans and other welfare fringe benefit plans.

On April 12, 2009, the Company and certain directors and officers, in their individual capacities, along with selected stockholders (including Empire Capital and certain affiliated entities), (referred to in this proxy statement as the selected stockholders), entered into a voting agreement pursuant to which the selected stockholders agreed to vote in favor of the adoption and approval of the Merger Agreement, the Merger and the transactions contemplated by the Merger Agreement. In addition, the selected stockholders agreed not to directly or indirectly transfer their respective shares of the Company’s Common Stock during the term of the voting agreement. As of —, 2009, the record date, the selected stockholders held and are entitled to vote, in the aggregate, — shares of the Company’s Common Stock, representing —% of the outstanding Company’s Common Stock. The selected stockholders include all directors and executive officers of the Company with the exception of director Douglas Schloss.

The following is a summary of the material U.S. federal income tax consequences of the Merger to U.S. persons (as defined below) whose shares of the Company’s Common Stock are converted into the right to receive cash in the Merger. This summary does not purport to consider all aspects of U.S. federal income taxation that might be relevant to our stockholders. For purposes of this discussion, we use the term “U.S. person” to mean a beneficial owner of shares of the Company’s Common Stock that is, for U.S. federal income tax purposes:

If a partnership (including an entity treated as a partnership for U.S. federal income tax purposes) holds the Company’s Common Stock, the tax treatment of a partner generally will depend on the status of the partners and the activities of the partnership. A partner of a partnership holding the Company’s Common Stock should consult its tax advisor.

This discussion is based on current law, which is subject to change, possibly with retroactive effect. It applies only to beneficial owners who hold shares of the Company’s Common Stock as capital assets, and may not apply to shares of the Company’s Common Stock received in connection with the exercise of employee stock options or otherwise as compensation, stockholders who hold an equity interest, directly or indirectly, in Newco or the Surviving Corporation after the Merger, or to certain types of beneficial owners who may be subject to special rules (such as insurance companies, banks, tax-exempt organizations, financial institutions, broker-dealers, partnerships, S corporations or other pass-through entities, mutual funds, traders in securities who elect the mark-to-market method of accounting, stockholders subject to the alternative minimum tax, stockholders that have a functional currency other than the U.S. dollar, or stockholders who hold the Company’s Common Stock as part of a hedge, straddle or a constructive sale or conversion transaction). This discussion does not address the receipt of cash in connection with the cancellation of shares of stock appreciation rights, restricted stock units or

options to purchase shares of the Company’s Common Stock, or any other matters relating to equity compensation or benefit plans. This discussion also does not address the U.S. tax consequences to any stockholder who, for U.S. federal income tax purposes, is a non-resident alien individual, foreign corporation, foreign partnership or foreign estate or trust, and does not address any aspect of state, local or foreign tax laws.

Conversion of Shares of the Company’s Common Stock into the Right to Receive Cash Pursuant to the Merger Agreement. The exchange of shares of the Company’s Common Stock for cash in the Merger will be a taxable transaction for U.S. federal income tax purposes. In general, a stockholder whose shares of the Company’s Common Stock are converted into the right to receive cash in the Merger will recognize capital gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount of cash received with respect to such shares and the stockholder’s adjusted tax basis in such shares. Gain or loss will be determined separately for each block of shares (i.e., shares acquired at the same cost in a single transaction). Such gain or loss will be long-term capital gain or loss provided that a stockholder’s holding period for such shares is more than 12 months at the time of the consummation of the Merger. Long-term capital gains of individuals are eligible for reduced rates of taxation. There are limitations on the deductibility of capital losses.

Backup Withholding and Information Reporting. Backup withholding of tax may apply to cash payments to which a non-corporate stockholder is entitled under the Merger Agreement, unless the stockholder or other payee provides a taxpayer identification number, certifies that such number is correct, and otherwise complies with the backup withholding rules. Each of our stockholders should complete and sign the Substitute Form W-9 included as part of the letter of transmittal and return it to the paying agent, in order to provide the information and certification necessary to avoid backup withholding, unless an exemption applies and is established in a manner satisfactory to the paying agent.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowable as a refund or a credit against a stockholder’s U.S. federal income tax liability provided the required information is timely furnished to the Internal Revenue Service.

Cash received in the Merger will also be subject to information reporting unless an exemption applies.

The U.S. federal income tax consequences described above are not intended to constitute a complete description of all tax consequences relating to the Merger. Because individual circumstances may differ, each stockholder should consult the stockholder’s tax advisor regarding the applicability of the rules discussed above to the stockholder and the particular tax effects to the stockholder of the Merger in light of such stockholder’s particular circumstances, the application of state, local and foreign tax laws, and, if applicable, the tax consequences of the receipt of cash in connection with the cancellation of options, stock appreciation rights or restricted stock units to purchase shares of the Company’s Common Stock, including the transactions described in this proxy statement relating to our other equity compensation and benefit plans.

If the Merger is completed, our Common Stock will be delisted from the NASDAQ and deregistered under the Exchange Act and we will no longer file periodic reports with the SEC on account of our Common Stock.

On April 21, 2009 a purported stockholder class action and derivative petition was filed in the District Court of Dallas County, Texas in connection with the announcement of the proposed merger entitled Cooper, et al. v. Entrust, et al., Cause No. DC-09-04802. On or about April 22, 2009, a separate purported stockholder class action and derivative petition was filed in the District Court of Dallas County, Texas in connection with the announcement of the proposed merger entitled Sachs v. Entrust, Inc., Cause No. DC-09-04813. The suits name as

defendants the Company and its board of directors as well as Newco and Merger Sub. Plaintiffs purport to represent the stockholders of Entrust who are similarly situated with them. Among other things, the petitions allege that our directors, in approving the proposed Merger breached fiduciary duties owed to our stockholders because they failed to take steps to maximize the value to our public stockholders. The petitions further allege that the Company and Newco aided and abetted the alleged breach of fiduciary duties. The petitions seek class certification, damages and certain forms of equitable relief, including enjoining the consummation of the Merger. Counsel for the Company was informed on April 23, 2009 that the plaintiffs in both petitions intend to seek to consolidate the two actions. We believe that plaintiffs’ allegations are without merit and intend to vigorously defend this action. There can be no assurance, however, that we will be successful in our defense of the action.

This section of the proxy statement describes the material provisions of the Merger Agreement but does not purport to describe all of the terms of the Merger Agreement. The following summary is qualified in its entirety by reference to the complete text of the Merger Agreement, which is attached as Annex A to this proxy statement and incorporated into this proxy statement by reference. We urge you to read the full text of the Merger Agreement because it is the legal document that governs the Merger. It is not intended to provide you with any other factual information about us. Such information can be found elsewhere in this proxy statement and in the public filings we make with the SEC, as described in the section entitled “Where You Can Find More Information” beginning on page 90.

The Merger Agreement provides for the Merger of Merger Sub with and into Entrust upon the terms, and subject to the conditions, of the Merger Agreement. As the surviving corporation, the Company will continue to exist following the Merger (the Company is sometimes referred to herein as the Surviving Corporation). Upon consummation of the Merger, the directors of Merger Sub will be the initial directors of the Surviving Corporation and the officers of Merger Sub will be the initial officers of the Surviving Corporation. All Surviving Corporation officers will hold their positions until their successors are duly elected.

We, Newco or Merger Sub may terminate the Merger Agreement prior to the consummation of the Merger in some circumstances, whether before or after the approval by our stockholders of the Merger. Additional details on termination of the Merger Agreement are described in “—Termination of the Merger Agreement” beginning on page 79.

The Merger will be effective at the time the articles of merger are filed with the State Department of Assessments and Taxation of Maryland (or at a later time, not to exceed thirty (30) days from the date of filing, if agreed in writing upon by the parties). We expect to complete the Merger as promptly as practicable after our stockholders approve the Merger.

Unless otherwise agreed by the parties to the Merger Agreement, the parties are required to close the Merger no later than the first business day after the satisfaction or waiver of the last to be satisfied or waived of the conditions described under “—Conditions to the Merger” beginning on page 75.

If the Merger is completed, each share of the Company’s Common Stock issued and outstanding immediately prior to the consummation of the Merger will be entitled to receive $1.85 in cash (which we sometimes refer to in this proxy statement as the Per Share Price or in the aggregate as the merger consideration), without interest and less any applicable withholding taxes.

After the Merger is effective, each holder of a certificate representing any shares of our Common Stock will no longer have any rights with respect to the shares, except for the right to receive the merger consideration.

Upon the consummation of the Merger, each then outstanding Company option, including unvested Company options, will be cancelled, and exchanged (A) in the case of any Company option that is vested in accordance with the terms of the applicable Company Stock Plan and has a per share exercise price less than $1.85, for the right to receive from the Surviving Corporation for each share of the Company’s Common Stock

Upon the consummation of the Merger, except as otherwise agreed to by Newco and a holder of a Company stock-based award, each right of any kind, contingent or accrued, to receive shares of the Company’s Common Stock or benefits measured by the value of a number of shares of the Company’s Common Stock, and each award of any kind consisting of shares of the Company’s Common Stock, in each case, granted under the Company Stock Plans (including restricted stock units, stock appreciation rights and performance stock units), other than Company Options, whether or not then vested, shall become fully vested and shall be converted automatically into the right to receive upon the consummation of the Merger an amount in cash in U.S. dollars equal to the product of (x) the total number of shares of the Company’s Common Stock subject to such Company stock-based award and (y) $1.85 (reduced, if applicable, by any exercise or base price applicable to such Company stock-based award) and each Company stock-based award shall be cancelled and shall only entitle the holder to the payment described above.

The effect of the Merger upon our other employee benefit plans is described under “—Employee Benefits” beginning on page 83.

Newco will designate a payment agent reasonably acceptable to us to make payment of the merger consideration as described above. Upon the consummation of the Merger, Newco will deposit, or Newco will cause to be deposited, with the payment agent the funds appropriate to pay the merger consideration to the stockholders, holders of Company stock-based awards and holders of stock options.

Promptly following the consummation of the Merger, Newco and the Surviving Corporation will cause the payment agent to send you a letter of transmittal and instructions advising you how to surrender your certificates and uncertificated shares in exchange for an amount in cash equal to the product obtained by multiplying the aggregate number of shares of the Company’s Common Stock represented by your certificate(s) or the uncertificated shares, as the case may be, and the Per Share Price (less any applicable withholding taxes payable in respect thereof). The payment agent will pay you your merger consideration after you have surrendered your certificates for cancellation to the payment agent together with the letter of transmittal duly completed and validly executed, or upon receipt of an “agent’s message” by the payment agent in the case of a book-entry transfer or uncertificated shares. Interest will not be paid or accrue in respect of the merger consideration. YOU SHOULD NOT FORWARD YOUR STOCK CERTIFICATES TO THE PAYMENT AGENT WITHOUT A LETTER OF TRANSMITTAL, AND YOU SHOULD NOT RETURN YOUR STOCK CERTIFICATES WITH THE ENCLOSED PROXY.

If any portion of the cash deposited with the payment agent remains undistributed within six (6) months following the consummation of the Merger, this undistributed cash will be delivered to the Surviving Corporation upon demand, subject to any applicable unclaimed property laws. Any unclaimed amounts in existence two (2) years after the consummation of the Merger, or at such earlier date as these amounts would become property of any government entity, will become the property of the Surviving Corporation free and clear of any prior claims or interest.

If you want the payment agent to pay some or all of your portion of the merger consideration to someone other than you, as the registered owner of a stock certificate or of uncertificated shares, you must have your certificate(s) properly endorsed or otherwise in proper form for transfer, and you must pay any transfer or other taxes payable by reason of the transfer or establish to the paying agent’s reasonable satisfaction that the taxes have been paid or are not required to be paid.

In the event that you have lost your certificate, or if it has been stolen or destroyed, the payment agent will only issue to you your portion of the merger consideration in exchange for such lost, stolen or destroyed certificates upon the making of an affidavit of that fact. Newco may, in its sole discretion and as a condition precedent to the payment of your portion of the merger consideration, require that you deliver a bond in an amount that directs as indemnity against any claim that may be made against Newco, the Surviving Corporation or the payment agent with respect of the lost, stolen or destroyed certificate.

The Merger Agreement contains representations and warranties made by us to Newco and Merger Sub and representations and warranties made by Newco and Merger Sub to us. The assertions embodied in those representations and warranties were made solely for purposes of the Merger Agreement and may be subject to important qualifications and limitations agreed by the parties in connection with negotiating its terms. Moreover, some of those representations and warranties may not be accurate or complete as of any particular date because they are subject to a contractual standard of materiality or a “Company Material Adverse Effect” (defined below) different from that generally applicable to public disclosures to stockholders or used for the purpose of allocating risk between the parties to the Merger Agreement rather than establishing matters of fact. For the foregoing reasons, you should not rely on the representations and warranties contained in the Merger Agreement as statements of factual information.

In the Merger Agreement, the Company, Newco and Merger Sub each made representations and warranties relating to, among other things:

In the Merger Agreement, Newco and Merger Sub also each made representations and warranties relating to:

Many of the Company’s representations and warranties are qualified by a material adverse effect standard. For purposes of the Merger Agreement, “Company Material Adverse Effect” is defined to mean any change, event, violation, inaccuracy, effect or circumstance (each, an “Effect”) that, individually or taken together with all other Effects that have occurred prior to the date of determination of the occurrence of the Company Material Adverse Effect, is or would reasonably be expected to be materially adverse to the business, financial condition or results of operations of the Company and our subsidiaries, taken as a whole, other than:

except in the case of the first seven (7) bullets above, to the extent such Effect has not had a disproportionate impact on the Company relative to other companies in the industries in which the Company and its subsidiaries conduct business.

We have agreed in the Merger Agreement that, until the consummation of the Merger, and unless the Merger Agreement is terminated pursuant to the termination provisions described hereinafter, we will (or will cause our subsidiaries to):

We have also agreed that, until the consummation of the Merger, except as expressly contemplated by the Merger Agreement and as set forth in the Company Disclosure Letter or approved by Newco (which approval will not be unreasonably withheld, delayed or conditioned), we and our subsidiaries will not:

Upon the terms and conditions set forth in the Merger Agreement, each of the parties to the Merger Agreement has agreed to take, or cause to be taken, all actions reasonably necessary, and to do, or cause to be done, and assist and cooperate with the other party or parties in doing, all things reasonably necessary, proper or advisable under applicable law to consummate the Merger in the most expeditious manner reasonably practicable, including using reasonable best efforts to cause the conditions of the Merger to be satisfied.

In the event that any state anti-takeover or other similar law is or becomes applicable to any of the transactions contemplated by the Merger Agreement, the parties have agreed to use their respective reasonable best efforts to ensure that the transactions contemplated by the Merger Agreement may be consummated as promptly as practicable on the terms and subject to the conditions set forth in the Merger Agreement and otherwise to minimize the effect of such law on the Merger.

Newco and Merger Sub have agreed to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to obtain the equity financing, including:

Furthermore, neither Newco nor Merger Sub will amend or agree to amend any term of the equity commitment letter without our prior written consent.

Newco and Merger Sub have agreed to use their respective commercially reasonable efforts to obtain the debt financing on the terms and conditions set forth in the debt commitment letter, or terms not materially less favorable to Newco or the Company, including:

Newco and Merger Sub may not amend or agree to amend any term of the debt commitment letter without the prior written consent of the Company if such amendment reduces the aggregate amount of the debt financing or amends the conditions precedent to the Debt Financing in a manner that could reasonably be expected to delay or prevent the closing date or make the funding of the debt financing less likely to occur.

However, Newco and Merger Sub may replace or amend the debt commitment letter so long as:

Prior to the consummation of the Merger, the Company has agreed to provide, or cause each of its subsidiaries to provide, and use its commercially reasonable efforts to cause its representatives, to provide, all cooperation reasonably requested by Newco in connection with the arrangement of the Debt Financing, including:

Notwithstanding the aforementioned restrictions, at all times during the period commencing as of 11:59 p.m., Eastern time, on May 13, 2009 (the “No-Shop Period Start Date”) and continuing until the approval of the Merger by our stockholders, we may participate or engage in discussions or negotiations with, furnish non-public information to, or afford access to the business, properties, assets, books, records or other non-public information, or to the personnel, of the Company or any of its subsidiaries pursuant to an Acceptable Confidentiality Agreement to:

We will promptly (within 24 hours) notify Newco in the event we receive an Acquisition Proposal, including the identity of the person making such Acquisition Proposal and material terms and conditions thereof and any request for information relating to the Company (including non-public information) or for access to the properties, book or records of the Company by any third party that has made an Acquisition Proposal, or receipt of an amendment to a previously disclosed Acquisition Proposal (including the terms of such amendment). We will promptly (within 24 hours) inform Newco of any change in the price, structure or form of consideration or terms and conditions of such Acquisition Proposal.

Promptly (and in any event, within 24 hours) upon the determination by our board of directors that an Acquisition Proposal constitutes a Superior Proposal, we shall notify Newco that the board has received a Superior Proposal, specifying in detail the terms and conditions of such Superior Proposal and the identity of the person making such Superior Proposal. The Company has agreed to, during the three (3) business day period following Newco’s receipt of a notice of a Superior Proposal, negotiate in good faith with Newco and to give Newco the opportunity to match or better such Superior Proposal.

An “Acceptable Confidentiality Agreement” means an agreement that is either (i) in effect as of the execution and delivery of the Merger Agreement or (ii) executed, delivered and effective after the execution, delivery and effectiveness of the Merger Agreement, in either case containing provisions that require any counter-party(ies) thereto (and any of its(their) representatives named therein) that receive material non-public information of or with respect to the Company to keep such information confidential, provided that such confidentiality provisions are no less restrictive in the aggregate to such counter-party(ies) (and any of its(their) representatives named therein) than the terms of the confidentiality agreement entered into by the Company and Newco. For the avoidance of doubt, an “Acceptable Confidentiality Agreement” need not contain any “standstill” or other similar provisions.

An “Acquisition Proposal” means any offer or proposal (other than an offer or proposal by Newco or Merger Sub) to engage in an Acquisition Transaction.

An “Acquisition Transaction” means any transaction or series of related transactions (other than the Merger) involving:

(i) any direct or indirect purchase or other acquisition by any person or “group” (as defined in or under Section 13(d) of the Exchange Act), whether from the Company and/or any other person(s), of shares of the Company’s Common Stock representing more than twenty percent (20%) of the Company’s Common Stock outstanding after giving effect to the consummation of such purchase or other acquisition, including pursuant to a tender offer or exchange offer by any person or “group” that, if consummated in accordance with its terms, would result in such person or “group” beneficially owning more than twenty percent (20%) of the Company’s Common Stock outstanding after giving effect to the consummation of such tender or exchange offer;

(ii) any direct or indirect purchase or other acquisition by any person or “group” (as defined in or under Section 13(d) of the Exchange Act) of more than twenty percent (20%) of the consolidated assets of the Company and its subsidiaries taken as a whole (measured by the fair market value thereof as of the date of such sale, transfer, acquisition or disposition); or

(iii) any merger, consolidation, business combination, recapitalization, reorganization, liquidation, dissolution or other similar transaction involving the Company pursuant to which any person or “group” (as defined in or under Section 13(d) of the Exchange Act), other than the Company stockholders (as a group) immediately prior to the consummation of such transaction, would hold shares of the Company’s Common Stock representing more than twenty percent (20%) of the Company’s Common Stock outstanding after giving effect to the consummation of such transaction.

A “Superior Proposal” means any written Acquisition Proposal for an Acquisition Transaction on terms that the Company board of directors shall have determined in good faith (after consultation with its financial advisor and outside legal counsel) would be more favorable to the Company stockholders (in their capacity as such) than the Merger; provided, however, that for purposes of the reference to an “Acquisition Proposal” in the definition of a “Superior Proposal,” all references to “twenty percent (20%) in the definition of “Acquisition Transaction” shall be references to “fifty percent (50%).”

A competing acquisition transaction has the same meaning as an “Acquisition Transaction” defined above except that all references therein to “twenty percent (20%)” shall be references to “fifty percent (50%).

Except as set forth below, all fees and expenses incurred in connection with the Merger Agreement will be paid by the party or parties incurring the expense whether or not the Merger is consummated.

The parties have agreed that in no event the Company will be required to pay the termination fee on more than one occasion, whether or not the termination fee may be payable under more than one provision of the Merger Agreement at the same time or at different times.

For a period of six (6) years following the consummation of the Merger, the Surviving Corporation shall cause the charters and bylaws of the Surviving Corporation to contain provisions with respect to indemnification, exculpation and advancement of expenses that are at least as favorable as the indemnification, exculpation and advancement of expenses set forth in the charters and bylaws of the Company as of the date of the Merger Agreement, and such provisions shall not be repealed, amended or otherwise modified in any manner except as required by applicable law.

In addition, for a period of six (6) years following the consummation of the Merger, the Surviving Corporation shall indemnify and hold harmless each current or former director and officer of the Company from and against any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, proceeding, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such claim, proceeding, investigation or inquiry arises directly or indirectly out of or pertains directly or indirectly to (i) any action or omission or alleged action or omission in an indemnified person’s capacity as a director, officer, employee or agent of the Company or any of its subsidiaries or other affiliates (regardless of whether such action or omission, or alleged action or omission, occurred prior to, at or after the consummation of the Merger), or (ii) any of the transactions contemplated by the Merger Agreement.

Moreover, during the period of six (6) years following the consummation of the Merger, the Surviving Corporation will (and Newco will cause the Surviving Corporation to) maintain in effect the Company’s current directors’ and officers’ liability insurance, or D&O Insurance, in respect of acts or omissions occurring at or prior to the consummation of the Merger, covering each person covered by the D&O Insurance.

For a period of six (6) months following the consummation of the Merger, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) either:

The Surviving Corporation has agreed to grant any continuing employee credit for all service with the Company and its subsidiaries prior to the consummation of the Merger for purposes of eligibility to participate, vesting and, solely for purposes of vacation accrual and severance pay, benefit entitlement. However, such service need not be credited under any equity-based or non-qualified deferred compensation plan or arrangement or to the extent that it would result in duplication of coverage or benefits. In addition, each Continuing Employee will be immediately eligible to participate in any new employee benefit plans sponsored by the Surviving Corporation and its subsidiaries to the extent coverage under any such new plan replaces coverage in the plan year in which the consummation of the Merger occurs under an old plan in which the continuing employee was previously participating. Moreover, for each new plan providing medical, dental, pharmaceutical, or vision benefits to any continuing employee, the Surviving Corporation shall use commercially reasonable efforts to cause all waiting periods, pre-existing condition exclusions, evidence of insurability requirements and actively-at-work or similar requirements of such new plan to be waived in the plan year in which the consummation of the Merger occurs for such continuing employee and his or her covered dependents to the extent waived or satisfied under the corresponding old plan as of the consummation of the Merger, and the Surviving Corporation shall use commercially reasonable efforts to cause any eligible expenses incurred by such continuing employee and his or her covered dependents during the portion of the plan year of the old plan ending on the date such employee’s participation in the corresponding new plan begins in the plan year in which the consummation of the Merger occurs to be given full credit under such new plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such continuing employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such new plan.

Finally, any vacation or paid time off accrued but unused by a continuing employee as of immediately prior to the consummation of the Merger shall be credited to such continuing employee following the consummation of the Merger to the extent reflected as a working capital liability on the Company’s balance sheet.

The parties may amend the Merger Agreement at any time, except that after our stockholders have approved the Merger, there shall be no amendment that by law requires further approval by our stockholders without such approval having been obtained. All amendments to the Merger Agreement must be in a writing signed by us, Newco and Merger Sub.

At any time before the consummation of the Merger, each of the parties to the Merger Agreement may, by written instrument and to the extent legally allowed:

The Company is entitled to seek an injunction to prevent or restrain breaches or threatened breaches of the Merger Agreement, the equity commitment letter or the guarantee, or to enforce specifically the terms of the Merger Agreement to prevent breaches or threatened breaches of, and to enforce compliance with, the covenants and obligations of Newco and Merger Sub under the Merger Agreement, the equity commitment letter and the guarantee. The Company also has the right to cause Newco and Merger Sub to fully enforce the terms of the equity commitment letter against the investor to the fullest extent permissible under the equity commitment letter and applicable laws and to cause the Merger to be consummated.

If the Merger is consummated, we will not have public stockholders and there will be no public participation in any future meeting of stockholders. However, if the Merger is not completed or if we are otherwise required to do so under applicable law, we would hold a 2010 annual meeting of stockholders, or 2010 Annual Meeting.

If a stockholder of the Company wishes to present a proposal before the 2010 Annual Meeting, but does not wish to have the proposal considered for inclusion in the Company’s proxy statement and proxy card, such stockholder must also give written notice to the Secretary of the Company at the address noted above. The Secretary must receive such notice not less than 60 days nor more than 90 days prior to the 2010 Annual Meeting; provided that, in the event that less than 70 days’ notice or prior public disclosure of the date of the 2010 Annual Meeting is given or made, notice by the stockholder must be received not later than the close of business on the 10th day following the date on which such notice of the date of the meeting was mailed or such public disclosure was made, whichever occurs first. If a stockholder fails to provide timely notice of a proposal to be presented at the 2010 Annual Meeting, the proxies designated by the board of directors of the Company will have discretionary authority to vote on any such proposal.

(d) Transfers of Ownership. In the event that a transfer of ownership of shares of Company Common Stock is not registered in the stock transfer books or ledger of the Company, or if the Per Share Price is to be paid in a name other than that in which the Certificates or Uncertificated Shares surrendered in exchange therefor are registered in the stock transfer books or ledger of the Company, the Per Share Price may be paid to a Person other than the Person in whose name the Certificate or Uncertificated Shares so surrendered is registered in the stock transfer books or ledger of the Company only if such Certificate is properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid to Newco (or any agent designated by Newco) any transfer or other Taxes required by reason of the payment of the Per Share Price to a Person other than the registered holder of such Certificate or Uncertificated Shares, or established to the satisfaction of Newco (or any agent designated by Newco) that such transfer or other Taxes have been paid or are otherwise not payable.

(g) Distribution of Exchange Fund to the Surviving Corporation. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates or Uncertificated Shares on the date that is six (6) months after the Effective Time shall be delivered to the Surviving Corporation upon demand, and any holders of shares of Company Common Stock that were issued and outstanding immediately prior to the Merger who have not theretofore surrendered their Certificates or Uncertificated Shares representing such shares of Company Common Stock for exchange pursuant to the provisions of this Section 2.8 shall thereafter look for payment of the Per Share Price payable in respect of the shares of Company Common Stock represented by such Certificates or Uncertificated Shares solely to the Surviving Corporation (subject to abandoned property, escheat or other similar laws), as general creditors thereof, for any claim to the applicable Per Share Price to which such holders may be entitled pursuant to the provisions of this Article II. Any amounts remaining unclaimed by holders of any such Company Common Stock two (2) years after the Effective Time or at such earlier date as is immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Authority shall, to the extent permitted by applicable law, become the property of the Surviving Corporation free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

The Per Share Price paid in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of the Company Common Stock. From and after the Effective Time, there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time, other than transfers to reflect, in accordance with customary settlement procedures, trades effected prior to the Effective Time. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.

2.10 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Payment Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Per Share Price payable in respect thereof pursuant to Section 2.7; provided, however, that Newco may, in its sole discretion and as a condition precedent to the payment of such Per Share Price, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Newco, the Surviving Corporation or the Payment Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.11 Necessary Further Actions. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger Sub, the directors and officers of the Company and Merger Sub shall take all such lawful and necessary action.

Each of Newco and Merger Sub has been formed solely for the purpose of engaging in the transactions contemplated hereby and, prior to the Effective Time, neither Newco nor Merger Sub will have engaged in any other business activities and will have incurred no liabilities or obligations other than as contemplated by this Agreement.

(a) Newco and Merger Sub have delivered to the Company a complete and accurate copy, as of the date of this Agreement, of (i) an executed commitment letter (the “Equity Commitment Letter”) from Thoma Bravo Fund IX, L.P. (the “Investor”) to provide, subject to the terms and conditions therein, equity financing in an aggregate amount sufficient to fully finance the Merger and other transactions contemplated by this Agreement (the “Equity Financing”), and (ii) an executed commitment letter, dated as of the date of this Agreement, from Wells Fargo Foothill, LLC and Bank of Montreal (the “Debt Commitment Letter” and, together with the Equity Commitment Letter, the “Commitment Letters”) to provide, subject to the terms and conditions therein, debt financing in an aggregate amount set forth therein (being collectively referred to as the “Debt Financing”, and together with the Equity Financing collectively referred to as the “Financing”).

(b) As of the date hereof, the Commitment Letters have not been amended or modified, and the commitments set forth in the Commitment Letters have not been withdrawn or rescinded in any respect. The Commitment Letters, in the form so delivered to the Company on the date hereof, are in full force and effect and each constitutes a legal, valid and binding obligation of Newco and, to the knowledge of Newco, the other parties thereto for so long as it remains in full force and effect. There are no conditions precedent or other contingencies related to the funding of the full amount of the Financing, other than as expressly set forth in the Commitment Letters. Subject to the conditions set forth in the Equity Commitment Letter, the aggregate proceeds of the Equity Financing contemplated by the Equity Commitment Letter, together with the available cash of the Company, will be sufficient to enable Newco and Merger Sub to consummate the Merger upon the terms contemplated by this Agreement, to make all payments contemplated by this Agreement in connection with the Merger (including payment of all amounts payable under Article II of this Agreement in connection with or as a result of the Merger) and to pay all fees and expenses associated therewith. As of the date of this Agreement, no event has occurred which, with or without notice, lapse of time or both, would constitute a default or breach on the part of Newco or Merger Sub under any term or condition of the Commitment Letters other than to the extent that any term or condition requires any action by, or otherwise relates to, the Company or any of its Subsidiaries. Assuming the accuracy of the Company’s representations and warranties contained herein, as of the date of this Agreement, neither Newco nor Merger Sub has any reason to believe that any of the conditions to the Financing will not be satisfied or that the Financing will not be available to Newco or Merger Sub on the date of the Closing. Newco has fully paid any and all commitment and other fees that have been incurred and are due and payable on or prior to the date hereof in connection with the Commitment Letters.

(c) As of the date hereof, none of Newco, Merger Sub or any of their respective Affiliates is a party to any Contracts, or has made or entered into any formal or informal arrangements or other understandings (whether or not binding), with any Company Stockholder that is not an officer or employee of the Company or one of its Subsidiaries concerning any investments to be made in, or contributions to be made to, Newco or Merger Sub in connection with the Merger and/or any other transactions contemplated by this Agreement other than as set forth in the Commitment Letters.

4.11 Management Arrangements. As of the date hereof, except as previously disclosed to the Company Board, there are no Contracts or any formal or informal arrangements or other understandings (whether or not binding) between Newco, Merger Sub or any of their respective Affiliates, on the one hand, and any director or officer of the Company, on the other hand, relating to this Agreement, the Merger or any other transactions contemplated by this Agreement (including as to any investments to be made in, or contributions to be made to, Newco or Merger Sub), or to the Surviving Corporation or any of its Subsidiaries, businesses or operations (including as to continuing employment) from and after the Closing.

4.12 Solvency. As of the Effective Time and immediately after giving effect to all of the transactions contemplated by this Agreement, including the Merger and the payment of the aggregate merger consideration pursuant hereto, and payment of all related fees and expenses of Newco, Merger Sub, the Company and their respective Subsidiaries in connection therewith, (i) the amount of the “fair saleable value” of the assets of each of the Surviving Corporation and its Subsidiaries will exceed (A) the value of all liabilities of the Surviving Corporation and such Subsidiaries, including contingent and other liabilities, and (B) the amount that will be required to pay the probable liabilities of the Surviving Corporation and such Subsidiaries on their existing debts (including contingent liabilities) as such debts become absolute and matured, (ii) each of the Surviving Corporation and its Subsidiaries will not have an unreasonably small amount of capital for the operation of the businesses in which it is engaged or proposed to be engaged, and (iii) each of the Surviving Corporation and its Subsidiaries will be able to pay its liabilities, including contingent and other liabilities, as they mature. For purposes of the foregoing, “not have an unreasonably small amount of capital for the operation of the businesses in which it is engaged or proposed to be engaged” and “able to pay its liabilities, including contingent and other liabilities, as they mature” means that such Person will be able to generate enough cash from operations, asset dispositions or refinancing, or a combination thereof, to meet its obligations as they become due.

4.13 No Other Company Representations or Warranties. Except for the representations and warranties set forth in Article III, Newco and Merger Sub hereby acknowledge and agree that (a) neither the Company or any of its Subsidiaries, nor any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, nor any other Person, has made or is making any other express or implied representation or warranty with respect to the Company or any of its Subsidiaries or their respective business or operations, including with respect to any information provided or made available to the Newco, Merger Sub or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, and (b) neither the Company or any of its Subsidiaries, nor or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, nor any other Person, will have or be subject to any liability or indemnification obligation or other obligation of any kind or nature to Newco, Merger Sub or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, resulting from the delivery, dissemination or any other distribution to Newco, Merger Sub or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, or the use by Newco, Merger Sub or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, of any such information provided or made available to any of them by the Company or any of its Subsidiaries, or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, including any information, documents, estimates, projections, forecasts or other forward-looking information, business plans or other material provided or made available to Newco, Merger Sub or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, in “data rooms,” confidential information memoranda or

management presentations in anticipation or contemplation of the Merger or any other transactions contemplated by this Agreement. Notwithstanding the foregoing, nothing in this Section 4.13 or this Agreement shall relieve any Person of liability for fraud or willful misconduct or prevent Newco and Merger Sub from relying on the representations and warranties of the Company set forth in this Agreement or the other agreements or certificates entered into or delivered by the Company in connection with this Agreement.

4.14 Non-Reliance on Company Estimates, Projections, Forecasts, Forward-Looking Statements and Business Plans.

Nothing herein or in the Debt Commitment Letter shall adversely affect the

obligation of Newco and Merger Sub to ensure that the Equity Financing contemplated by the Equity Commitment Letter is sufficient to fully finance the Merger and the other transactions contemplated by this Agreement.

(b) Neither Newco nor Merger Newco shall amend, alter, or waive, or agree to amend, alter or waive (in any case whether by action or inaction), any term of the Debt Commitment Letter without the prior written consent of the Company if such amendment, alteration or waiver reduces the aggregate amount of the Debt Financing or amends the conditions precedent to the Debt Financing in a manner that would reasonably be expected to delay or prevent the Closing Date or make the funding of the Debt Financing less likely to occur; provided, however, that Newco and Merger Sub may replace and/or amend the Debt Commitment Letter so long as (i) the terms are not materially less favorable to Newco or the Company, including with respect to conditionality thereof, and (ii) the conditions to the Debt Financing set forth in the Debt Commitment Letter as of the date hereof would not be materially expanded in a manner that would reasonably be expected to delay or prevent the Closing; and in any such event Newco shall disclose to the Company its intention to obtain such alternative financing, shall keep the Company informed of the terms thereof and shall deliver to the Company final drafts of the commitment letter (the “New Debt Commitment Letter”) providing for such alternative financing and, if requested to do so, the Company shall within a reasonable time (and in no event more than three (3) Business Days thereafter) inform Newco as to whether it agrees that such alternative financing is on terms not materially less favorable (including, with respect to the conditionality thereof) to the Company than the Debt Commitment Letter. If the Company so agrees, the term “Debt Financing” as used herein shall be deemed to mean the Debt Financing contemplated by the Debt Commitment Letter to the extent not so superseded at the time in question and the New Debt Commitment Letter to the extent then in effect. Newco shall promptly (and in any event within one Business Day) notify the Company of the expiration or termination (or attempted or purported termination, whether or not valid) of the Debt Commitment Letter.

(c) Prior to the Effective Time, the Company shall (and the Company shall cause each of its Subsidiaries to) provide, and shall use its commercially reasonable efforts to cause its Representatives, to provide, all cooperation reasonably requested by Newco in connection with the arrangement of the Debt Financing, including (i) assisting with the preparation of materials for bank information memoranda and similar documents required in connection with the Debt Financing; provided, however, that any such memoranda and similar documents need not be issued by the Company or its Subsidiaries; provided, further, that, any such memoranda shall contain disclosure and financial statements with respect to the Company and its Subsidiaries reflecting the Company and its Subsidiaries as the obligor, (ii) executing and delivering customary guarantee, pledge and security documents and related officer certificates or other documents as may be reasonably requested by Newco (including certificates of the chief financial officer of the Company or its Subsidiaries with respect to solvency and other customary matters for use in their reports in any materials relating to the Debt Financing) and otherwise reasonably facilitating the guaranteeing of obligations and the pledging of collateral, (iii) furnishing Newco and its financing sources with financial and other pertinent information regarding the Company and its Subsidiaries as may be reasonably requested by Newco or its financing sources, including information related to the Company or its Subsidiaries required by regulatory authorities including under applicable “know your customer” and anti money laundering rules and regulations, including the Patriot Act, and (iv) permitting the prospective lenders involved in the Debt Financing to evaluate and appraise the Company’s and its Subsidiaries’ current assets and liabilities, cash management and accounting systems, policies and procedures relating thereto for the purpose of establishing collateral arrangements; provided, however, that the notwithstanding the foregoing, no obligations of the Company, its Subsidiaries or their Representatives under any such agreement, certificate, document or instrument shall be effective until the Effective Time; provided, further, that nothing herein shall require such cooperation to the extent it would interfere unreasonably with the business or operations of the Company or its Subsidiaries; and provided, further, that neither the Company nor any of its Subsidiaries shall be required to pay any commitment fee or similar fee or incur any liability with respect to the Debt Financing prior to the Effective Time. Newco shall, promptly upon request by the Company, reimburse the Company for all reasonable and documented out-of-pocket costs incurred by the Company in

connection with such cooperation. The Company and each of its Subsidiaries hereby consent to the use of its logos in connection with the Debt Financing, provided that such logos are used solely in a manner that is not intended to nor reasonably likely to harm or disparage the Company or its Subsidiaries or the reputation or goodwill of the Company or its Subsidiaries.

6.8 Anti-Takeover Laws. In the event that any state anti-takeover or other similar law is or becomes applicable to any of the transactions contemplated by this Agreement, the Company, Newco and Merger Sub shall use their respective reasonable best efforts to ensure that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms and subject to the conditions set forth in this Agreement and otherwise to minimize the effect of such law on this Agreement and the transactions contemplated hereby.

6.9 Access. At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article VIII and the Effective Time, the Company shall afford Newco and its financial advisors, business consultants, legal counsel, accountants and other agents and representatives reasonable access during normal business hours, upon reasonable notice, to the properties, books and records and personnel of the Company; provided, however, that the Company may restrict or otherwise prohibit access to any documents or information to the extent that (a) any applicable law or regulation (including any laws or regulations relating to security clearances) requires the Company to restrict or otherwise prohibit access to such documents or information, (b) access to such documents or information would give rise to a material risk of waiving any attorney-client privilege, work product doctrine or other applicable privilege applicable to such documents or information, or (c) access to a Contract to which the Company or any of its Subsidiaries is a party or otherwise bound would violate or cause a default under, or give a third party the right to terminate or accelerate the rights under, such Contract (provided that the Company and Newco shall cooperate in good faith to design and implement alternative procedures to enable Newco to evaluate any such Contracts without causing a violation or default thereunder or giving any third party a right to terminate or accelerate the rights thereunder); and provided further, that nothing in this Section 6.9 or elsewhere in this Agreement shall be construed to require the Company or its Representatives to prepare any reports, analyses, appraisals, opinions or other information. Any investigation conducted pursuant to the access contemplated by this Section 6.9 shall be conducted in a manner that does not unreasonably interfere with the conduct of the business of the Company and its Subsidiaries or create a risk of damage or destruction to any property or assets of the Company or any of its Subsidiaries. Any access to the Company’s properties shall be subject to the Company’s reasonable security measures and insurance requirements and shall not include the right to perform invasive testing. The terms and conditions of the Confidentiality Agreement shall apply to any information obtained by Newco or any of its financial advisors, business consultants, legal counsel, accountants and other agents and representatives in connection with any investigation conducted pursuant to the access contemplated by this Section 6.9.

6.10 Section 16(b) Exemption. The Company shall take all actions reasonably necessary to cause the transactions contemplated by this Agreement and any other dispositions of equity securities of the Company (including derivative securities) in connection with the transactions contemplated by this Agreement by each individual who is a director or executive officer of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

(a) The Surviving Corporation and its Subsidiaries shall honor and fulfill in all respects the obligations of the Company and its Subsidiaries under any and all indemnification agreements between the Company or any of its Subsidiaries and any of their respective current or former directors and officers and any person who becomes a director or officer of the Company or any of its Subsidiaries prior to the Effective Time (the “Indemnified Persons”). In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation and its Subsidiaries shall (and the Surviving Corporation shall cause its Subsidiaries to) cause the charters and bylaws (and other similar

organizational documents) of the Surviving Corporation and its Subsidiaries to contain provisions with respect to indemnification, exculpation and the advancement of expenses that are at least as favorable as the indemnification, exculpation and advancement of expenses provisions set forth in the Charter and bylaws (or other similar organizational documents) of the Company and its Subsidiaries as of the date hereof, and during such six-year period such provisions shall not be repealed, amended or otherwise modified in any manner except as required by applicable law.

(b) Without limiting the generality of the provisions of Section 6.11(a), during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall indemnify and hold harmless each Indemnified Person from and against any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, proceeding, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such claim, proceeding, investigation or inquiry arises directly or indirectly out of or pertains directly or indirectly to (i) any action or omission or alleged action or omission in such Indemnified Person’s capacity as a director, officer, employee or agent of the Company or any of its Subsidiaries or other Affiliates (regardless of whether such action or omission, or alleged action or omission, occurred prior to, at or after the Effective Time), or (ii) any of the transactions contemplated by this Agreement; provided, however, that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Person delivers to the Surviving Corporation a written notice asserting a claim for indemnification under this Section 6.11(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In the event of any such claim, proceeding, investigation or inquiry, (i) the Surviving Corporation shall have the right to control the defense thereof after the Effective Time (it being understood that, by electing to control the defense thereof, subject to the terms and conditions of this Section 6.11(b) (including, without limitation, the right of the Surviving Corporation to dispute that an Indemnified Person is entitled to indemnification pursuant to this Section 6.11), the Surviving Corporation will be deemed to have waived any right to object to the Indemnified Person’s entitlement to indemnification hereunder with respect thereto), (ii) each Indemnified Person shall be entitled to retain his or her own counsel, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry, (iii) the Surviving Corporation shall only be required to pay the reasonable fees and expenses of any counsel if the Surviving Corporation elects not to control the defense of any such claim, proceeding, investigation or inquiry, other than any fees and expenses of such separate counsel that are incurred prior to the date upon which the Surviving Corporation effectively assumes control of such defense (which, notwithstanding the foregoing, shall be borne and paid for by the Surviving Corporation) and (iv) no Indemnified Person shall be liable for any settlement effected without his or her prior express written consent. Notwithstanding anything to the contrary set forth in this Section 6.11(b) or elsewhere in this Agreement, neither the Surviving Corporation nor any of its Affiliates (including Newco) shall settle or otherwise compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, proceeding, investigation or inquiry for which indemnification may be sought by an Indemnified Person under this Agreement unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Persons from all liability arising out of such claim, proceeding, investigation or inquiry. Notwithstanding anything to the contrary set forth in this Section 6.11(b) or elsewhere in this Agreement, in no event shall the Surviving Corporation or any of its Affiliates (including Newco) have any obligation to indemnify and hold harmless any Indemnified Person with respect to any claim, proceeding, investigation, inquiry or other matter if such indemnification is prohibited by applicable law.

(c) During the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) maintain in effect the Company’s current directors’ and officers’ liability insurance (“D&O Insurance”) in respect of acts or omissions occurring at or prior to the Effective Time, covering each person covered by the D&O Insurance, on terms with respect to the coverage and amounts that are equivalent to those of the D&O Insurance; provided, however, that in satisfying its obligations under this Section 6.11(c), the Surviving Corporation shall not be obligated to pay annual premiums in excess of two hundred percent (200%) of the amount paid by the Company for coverage for its last full fiscal year (such two hundred percent

(200%) amount, the “Maximum Annual Premium”) (which premiums the Company represents and warrants to be as set forth in Section 6.11(c) of the Company Disclosure Letter); provided, however, that that if the annual premiums of such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase a six-year “tail” prepaid policy on the D&O Insurance at a price not to exceed the Maximum Annual Premium. In the event that the Company elects to purchase such a “tail” policy prior to the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) maintain such “tail” policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other obligations of the Surviving Corporation (and Newco) under the first sentence of this Section 6.11(c) for so long as such “tail” policy shall be maintained in full force and effect.

(d) If the Surviving Corporation (or Newco) or any of its successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation shall assume all of the obligations of the Surviving Corporation (or Newco) set forth in this Section 6.11.

(e) The obligations set forth in this Section 6.11 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Person (or any other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives)) without the prior written consent of such affected Indemnified Person or other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives). Each of the Indemnified Persons or other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives) are intended to be third party beneficiaries of this Section 6.11, with full rights of enforcement against the Surviving Corporation (and Newco) as if a party thereto. The rights of the Indemnified Persons (and other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives)) under this Section 6.11 shall be in addition to, and not in substitution for, any other rights that such persons may have under the charters, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Company or any of its Subsidiaries, or applicable law (whether at law or in equity).

(f) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 6.11 is not prior to or in substitution for any such claims under such policies.

(a) From and after the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) honor the Employee Plans set forth on Schedule 6.12 (the “Continuing Plans”) in accordance with their terms as in effect immediately prior to the Effective Time, provided that nothing in this sentence shall prohibit the Surviving Corporation from amending or terminating any such Employee Plans, arrangements or agreements in accordance with their terms or if otherwise required by applicable law.

(b) The Surviving Corporation or one of its Subsidiaries shall (and Newco shall cause the Surviving Corporation or one of its Subsidiaries to), offer employment by the Surviving Corporation or one of its Subsidiaries to all employees of the Company and its Subsidiaries as of the Effective Time by taking such actions as required under applicable law, including by offering to enter into an offer letter and/or related agreement (or similar document as appropriate) with such employees. For a period of six months following

the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) either (i) maintain for the benefit of each Continuing Employee the Continuing Plans (but excluding equity based benefits, any bonus or incentive plans, and individual employment agreements) at benefit levels that are no less than those in effect at the Company or its Subsidiaries on the date of this Agreement other than equity based benefits, any bonus or incentive plans, and individual employment agreements, or (ii) provide compensation, and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) to each Continuing Employee that, taken as a whole, are no less favorable in the aggregate than the compensation and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) provided to such Continuing Employee immediately prior to the Effective Time (“Comparable Plans”), or (iii) provide some combination of (i) and (ii) above such that each Continuing Employee receives compensation and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) that, taken as a whole, are no less favorable in the aggregate than the compensation and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) provided to such Continuing Employee immediately prior to the Effective Time.

(c) To the extent that a Continuing Plan or Comparable Plan is made available to any Continuing Employee on or following the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) cause to be granted to such Continuing Employee credit for all service with the Company and its Subsidiaries prior to the Effective Time for purposes of eligibility to participate, vesting and, solely for purposes of vacation accrual and severance pay, benefit entitlement; provided, however, that such service need not be credited under any equity-based or non-qualified deferred compensation plan or arrangement or to the extent that it would result in duplication of coverage or benefits. In addition, and without limiting the generality of the foregoing: (i) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all employee benefit plans sponsored by the Surviving Corporation and its Subsidiaries (other than the Continuing Plans or Comparable Plans) (such plans, collectively, the “New Plans”) to the extent coverage under any such New Plan replaces coverage in the plan year in which the Effective Time occurs under a Continuing Plan in which such Continuing Employee participates immediately before the Effective Time (such plans, collectively, the “Old Plans”); and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical, or vision benefits to any Continuing Employee, the Surviving Corporation shall use commercially reasonable efforts to cause all waiting periods, pre-existing condition exclusions, evidence of insurability requirements and actively-at-work or similar requirements of such New Plan to be waived in the plan year in which the Effective Time occurs for such Continuing Employee and his or her covered dependents to the extent waived or satisfied under the corresponding Old Plan as of the Effective Time, and the Surviving Corporation shall use commercially reasonable efforts to cause any eligible expenses incurred by such Continuing Employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such employee’s participation in the corresponding New Plan begins in the plan year in which the Effective Time occurs to be given full credit under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan. Any vacation or paid time off accrued but unused by a Continuing Employee as of immediately prior to the Effective Time shall be credited to such Continuing Employee following the Effective Time to the extent reflected as a working capital liability on the Company’s balance sheet.

(d) No provision of this Agreement shall be deemed to (i) guarantee employment for any period of time for, or preclude the ability of Newco or the Surviving Corporation or any of their Affiliates to terminate, any Continuing Employee at any time and for any or no reason, or (ii) subject to the limitations and requirements specifically set forth in this Section 6.12, require Newco or the Surviving Corporation to continue any Continuing or Comparable Plan or prevent the amendment, modification or termination thereof after the Effective Time, or (iii) create any third-party beneficiary rights or obligations in any Person (including any Continuing Employee or any dependent or beneficiary thereof) other than the parties to this Agreement.

6.13 Obligations of Merger Sub. Newco shall take all action necessary to cause Merger Sub and the Surviving Corporation to perform their respective obligations under this Agreement and to consummate the transactions contemplated hereby upon the terms and subject to the conditions set forth in this Agreement.

(a) At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article VIII and the Effective Time, the Company shall give prompt notice to Newco and Merger Sub upon becoming aware that any representation or warranty made by it in this Agreement has become untrue or inaccurate in any material respect, or of any failure of the Company to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of the Company set forth in this Agreement or the conditions to the obligations of Newco and Merger Sub to consummate the transactions contemplated by this Agreement or the remedies available to the parties hereunder; and provided further, that the terms and conditions of the Confidentiality Agreement shall apply to any information provided to Newco pursuant to this Section 6.14(a).

(b) At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article IX and the Effective Time, Newco shall give prompt notice to the Company upon becoming aware that any representation or warranty made by Newco or Merger Sub in this Agreement has become untrue or inaccurate in any material respect, or of any failure of Newco or Merger Sub to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of Newco or Merger Sub set forth in this Agreement or the conditions to the obligations of the Company to consummate the transactions contemplated by this Agreement or the remedies available to the parties hereunder; and provided further, that the terms and conditions of the Confidentiality Agreement shall apply to any information provided to the Company pursuant to this Section 6.14(b).

6.15 Public Statements and Disclosure. Neither the Company, on the one hand, nor Newco and Merger Sub, on the other hand, shall issue any public release or make any public announcement or disclosure concerning this Agreement or the Merger without the prior written consent of the other party(ies) (which consent shall not be unreasonably withheld, delayed or conditioned), except as such release, announcement or disclosure may be required by applicable law or the rules or regulations of any applicable securities exchange or regulatory or Governmental Authority to which the relevant party is subject or submits, wherever situated, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other party(ies) hereto reasonable time to comment on such release or announcement in advance of such issuance (it being understood that the final form and content of any such release or announcement, as well as the timing of any such release or announcement, shall be at the final discretion of the disclosing party); provided, however, that the restrictions set forth in this Section 6.15 shall not apply to any release, announcement or disclosure made or proposed to be made by the Company pursuant to Section 6.5.

6.16 Company Stockholder, Director and Management Arrangements. Except to the extent expressly authorized by the Company Board or any authorized committee thereof in advance, prior to the Effective Time, none of Newco, Merger Sub or any of their respective Affiliates shall enter into any Contract, and none of Newco, Merger Sub or any of their respective Affiliates shall make or enter into any formal or informal arrangements or other understandings (whether or not binding), with any Company Stockholder, or any director or officer of the Company, relating (i) to this Agreement, the Merger or any other transactions contemplated by this Agreement, including as to any investment to be made in, or contributions to be made to, Newco or Merger Sub, or (ii) to the Surviving Corporation or any of its Subsidiaries, businesses or operations (including as to continuing employment) from and after the Closing.

Notwithstanding anything set forth herein to the contrary, the institution of any Legal Proceeding by the Company (or its Affiliates) against Newco, Merger Sub, the Guarantor, the Investor or any of their respective Affiliates shall not preclude, limit or otherwise impair the ability of Newco and Merger Sub to consummate the Merger and the other transactions contemplated hereby during the pendency of such Legal Proceeding. If Newco and Merger Sub consummate the Merger and the other transactions contemplated hereby at any time during which any Legal Proceeding is pending between the Company and Newco, Merger Sub, the Guarantor, the Investor or any of their respective Affiliates in connection with this Agreement or any of the transactions contemplated hereby, the Company (and its Affiliates) shall agree to dismiss any such Legal Proceeding with prejudice effective as of the Effective Time. During the pendency of any such Legal Proceeding, the Company shall not take any action, or omit to take any action, that is intended (or would reasonably be expected) to preclude, limit or otherwise impair the ability of Newco and Merger Sub to consummate the Merger and the other transactions contemplated hereby.

(i) In the event that (A) this Agreement is validly terminated pursuant to Section 8.1(c) or Section 8.1(d), (B) following the execution and delivery of this Agreement and prior to the termination of this Agreement pursuant to Section 8.1(c) or Section 8.1(d), a Competing Acquisition Transaction shall have been publicly announced and not withdrawn or otherwise abandoned, and (C) within one year following the termination of this Agreement pursuant to Section 8.1(c) or Section 8.1(d), either the Competing Acquisition Transaction referenced in the immediately preceding clause (B) is consummated or the Company enters into a definitive agreement providing for the Competing Acquisition Transaction referenced in the immediately preceding clause (B) and, whether or not during such one-year period, such Competing Acquisition Transaction is subsequently consummated, then the Company shall pay to Newco the Company Termination Fee (less any cash amounts previously paid pursuant to Section 8.3(b)(iv)), by wire transfer of immediately available funds to an account or accounts designated in writing by Newco, concurrently with the consummation of such Competing Acquisition Transaction.

(ii) In the event that this Agreement is validly terminated pursuant to Section 8.1(f), the Company shall pay to Newco the Company Termination Fee, by wire transfer of immediately available funds to an account or accounts designated in writing by Newco, within two (2) Business Days following the occurrence of such termination.

9.5 Entire Agreement. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Company Disclosure Letter and the Guarantee, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof; provided, however, the Confidentiality Agreement shall not be superseded, shall survive any termination of this Agreement and shall continue in full force and effect until the earlier to occur of (a) the Effective Time and (b) the date on which the Confidentiality Agreement expires in accordance with its terms or is validly terminated by the parties thereto. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, NEITHER NEWCO AND MERGER SUB,ON THE ONE HAND, NOR THE COMPANY, ON THE OTHER HAND, MAKES ANY REPRESENTATIONS OR WARRANTIES TO THE OTHER, AND EACH PARTY HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, OR AS TO THE ACCURACY OR COMPLETENESS OF ANY OTHER INFORMATION, MADE (OR MADE AVAILABLE BY) BY ITSELF OR ANY OF ITS REPRESENTATIVES, WITH RESPECT TO, OR IN CONNECTION WITH, THE NEGOTIATION, EXECUTION OR DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO THE OTHER OR THE OTHER’S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING.

9.6 Third Party Beneficiaries. This Agreement is not intended to, and shall not, confer upon any other Person any rights or remedies hereunder, except (a) as set forth in or contemplated by the terms and provisions of Section 6.11, (b) prior to the Effective Time, for the right of holders of shares of the Company Common Stock to pursue claims for damages (including damages based on loss of the economic benefits of the transaction to Company Stockholders) and other relief (including equitable relief) for any breach of this Agreement by Newco or Merger Sub, whether or not this Agreement has been validly terminated pursuant to Article VIII, which right is hereby expressly acknowledged and agreed by Newco and Merger Sub, and (c) from and after the Effective Time, the rights of holders of shares of the Company Common Stock to receive the merger consideration set

forth in Article II. The rights granted pursuant to clause (b) of this Section 9.6 shall only be enforceable on behalf of Company Stockholders by the Company in its sole and absolute discretion, as agent for the Company Stockholders, it being understood and agreed that any and all interests in such claims shall attach to such shares of the Company Common Stock and subsequently transfer therewith and, consequently, any damages, settlements or other amounts recovered or received by the Company with respect to such claims (net of expenses incurred by the Company in connection therewith) may, in the Company’s sole and absolute discretion, be (A) distributed, in whole or in part, by the Company to the holders of shares of Company Common Stock of record as of any date determined by the Company or (B) retained by the Company for the use and benefit of the Company on behalf of its stockholders in any manner the Company deems fit. In addition, the Company hereby agrees that it will only accept the payment of any damages awarded pursuant to claims brought under clause (b) of this Section 9.6 if Newco and Merger Sub are found to be in breach of their respective obligations to consummate the Merger under Article II of this Agreement and a court of competent jurisdiction has declined to specifically enforce the obligations of Newco and Merger Sub to consummate the Merger pursuant to a claim for specific performance brought against Newco and Merger Sub pursuant to Section 9.8(b) and applicable law.

9.7 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

(b) The parties hereto hereby agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties hereto acknowledge and hereby agree that in the event of any breach or threatened breach by the Company, on the one hand, or Newco and Merger Sub, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Equity Commitment Letter or the Guarantee, the Company, on the one hand, and Newco and Merger Sub, on the other hand, shall be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement, the Equity Commitment Letter and the Guarantee by the other (as applicable), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement, the Equity Commitment Letter and the Guarantee, and this right shall include the right of the Company to cause Newco and Merger Sub to fully enforce the terms of the Equity Commitment letter against the Investor to the fullest extent permissible pursuant to the Equity Commitment Letter and applicable laws and to thereafter cause the Merger to be consummated. Newco and Merger Sub hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by Newco or Merger Sub, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of Newco and Merger Sub under this Agreement. The parties hereto further agree that (x) by seeking the remedies provided for in this Section 9.8(b), a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement, the Equity Commitment Letter or the Guarantee (including monetary damages) in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 9.8(b) are not available or

otherwise are not granted, and (y) nothing set forth in this Section 9.8(b) shall require any party hereto to institute any proceeding for (or limit any party’s right to institute any proceeding for) specific performance under this Section 9.8(b) prior or as a condition to exercising any termination right under Article VIII (and pursuing damages after such termination), nor shall the commencement of any Legal Proceeding pursuant to this Section 9.8(b) or anything set forth in this Section 9.8(b) restrict or limit any party’s right to terminate this Agreement in accordance with the terms of Article VIII or pursue any other remedies under this Agreement, the Equity Commitment Letter or the Guarantee that may be available then or thereafter. Notwithstanding anything set forth herein to the contrary, from and after the Effective Time, none of the Company, its Affiliates, or their respective current or former directors, officers or employees shall be entitled to seek or recover monetary or other damages or relief (including equitable relief) against Newco, the Surviving Corporation, the Guarantor, the Investor or any of their respective Affiliates in connection with this Agreement or the transactions contemplated hereby, except for claims to receive merger consideration pursuant to Section 9.6(c). If any Legal Proceedings seeking monetary or other damages or relief (including equitable relief) instituted by the Company or its Affiliates against Newco, Merger Sub, the Guarantor, the Investor or any of their respective Affiliates are pending as of the Effective Time, the Company shall cause such Legal Proceedings to be dismissed with prejudice as of the Effective Time.

We understand that Entrust, Inc. (the “Company”) intends to enter into a transaction with HAC Holdings, Inc. (“Newco”), pursuant to which, among other things (i) HAC Acquisition Corporation, a wholly owned subsidiary of Newco (“Merger Sub”), will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Newco, and (ii) at the effective time of the Merger each share of common stock, par value $0.01 per share, of the Company (“Company Common Stock”) that is outstanding immediately prior to the effective time of the Merger (other than shares of Company Common Stock that are held by the Company as treasury stock or owned by Newco or Merger Sub, or by any direct or indirect wholly-owned subsidiary of Newco or Merger Sub) will be canceled and extinguished and automatically converted into the right to receive cash in an amount equal to $1.85 (the “Consideration”). The terms and conditions of the proposed transaction are set forth in more detail in the Agreement and Plan of Merger, dated as of the date hereof, among Newco, Merger Sub and the Company (the “Agreement”).

We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company’s stockholders of the Consideration to be offered to such stockholders in the Merger. We have not been requested to opine as to, and our opinion does not in any manner address, the Company’s underlying business decision to proceed with or effect the proposed transaction. In addition, we express no opinion on, and our opinion does not in any manner address, the fairness of the amount or the nature of any compensation to any officers, directors or employees of any parties to the proposed transaction, or any class of such persons, relative to the consideration to be offered to the stockholders of the Company in the Merger.

In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the proposed transaction, (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including its Annual Report on Form 10-K for the fiscal year ended December 31, 2008, (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including financial projections of the Company prepared by management of the Company (the “Management Projections”), (4) published estimates of independent research analysts with respect to the future financial performance of the Company for calendar years 2009 and 2010, and extrapolations of such estimates for calendar years 2011 through 2014 prepared by management of the Company (collectively, the “Street Estimates”), and price targets of the Company published by such independent research analysts, (5) a trading history of the Company Common Stock from April 6, 2007 to April 6, 2009 and a comparison of that trading history with those of other companies that we deemed relevant, (6) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant, and (7) a

comparison of the financial terms of the proposed transaction with the financial terms of certain other transactions that we deemed relevant. In addition, we have had discussions with the management of the Company concerning its business, operations, assets, liabilities, financial condition and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate.

In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without any independent verification of such information and have further relied upon the assurances of the management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the Management Projections, upon the advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and that the Company will perform substantially in accordance with such projections. In addition, for the purposes of our analysis and with your consent, we have also relied on the Street Estimates. You have agreed with the appropriateness of the use of, and our reliance upon, such Street Estimates in performing our analysis. We assume no responsibility for and we express no view as to any such projections or estimates or the assumptions on which they are based. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. In addition, you have not authorized us to solicit, and we have not solicited, any indications of interest from any third party with respect to the purchase of all or a part of the Company’s business. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. We assume no responsibility for updating or revising our opinion based on events or circumstances that may occur after the date of this letter.

We have assumed the accuracy of the representations and warranties contained in the Agreement and all agreements related thereto. We have also assumed, upon the advice of the Company, that all material governmental, regulatory and third party approvals, consents and releases for the proposed transaction will be obtained within the constraints contemplated by the Agreement and that the proposed transaction will be consummated in accordance with the terms of the Agreement without waiver, modification or amendment of any term, condition or agreement thereof that would be material to our analyses. We do not express any opinion as to any tax or other consequences that might result from the proposed transaction, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that the Company has obtained such advice as it deemed necessary from qualified professionals.

Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Consideration to be offered to the stockholders of the Company in the Merger is fair to such stockholders.

We have acted as financial advisor to the Company in connection with the proposed transaction and will receive fees for our services, a portion of which is payable upon rendering this opinion and a substantial portion of which is contingent upon the consummation of the proposed transaction. In addition, the Company has agreed to reimburse our expenses and indemnify us for certain liabilities that may arise out of our engagement. We may perform from time to time various investment banking and financial services for the Company and affiliates (including portfolio companies) of Thoma Bravo and expect to receive customary fees for such services. In the ordinary course of our business, we actively trade in the equity securities (and any derivatives thereof) of the Company for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities (and any derivatives thereof).

This opinion, the issuance of which has been approved by our Fairness Opinion Committee, is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the proposed transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the proposed transaction.
