Item 1.01.    Entry into a Material Definitive Agreement.

Merger Agreement

        On May 15, 2011, Kratos Defense & Security Solutions, Inc., a Delaware corporation (the "Company"), Integral Systems, Inc., a Maryland corporation ("Integral Systems") (NASDAQ: ISYS), IRIS Merger Sub Inc., a Maryland corporation and a wholly-owned subsidiary of the Company, and IRIS Acquisition Sub LLC, a Maryland limited liability company and a wholly-owned subsidiary of the Company, entered into an Agreement and Plan of Merger (the "Merger Agreement"). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Integral Systems, and Integral Systems will continue as the surviving corporation and as a wholly-owned subsidiary of the Company (the "Merger"). The boards of directors of the Company and Integral Systems have unanimously approved the Merger Agreement and the transactions contemplated thereby.

        At the effective time of the Merger (the "Effective Time"), holders of Integral Systems common stock will be entitled to receive (i) $5.00 in cash, without interest, and (ii) 0.588 shares of the Company's common stock for each share of Integral Systems common stock they own (the "Merger Consideration").

        In addition, at the Effective Time, each Integral Systems stock option that has an exercise price less than $13.00 per share shall, if the holder thereof elects in writing, be cancelled in exchange for an amount in cash equal to the product of the total number of shares of Integral Systems common stock subject to such in-the-money option, multiplied by the aggregate value of the excess, if any, of $13.00 over the exercise price per share subject to such option, less the amount of any tax withholding. Each Integral Systems stock option that has an exercise price equal to or greater than $13.00 per share and each Integral Systems in-the-money option the holder of which does not make the election described in the preceding sentence shall be converted into an option to purchase Kratos common stock, with (i) the number of shares subject to such option adjusted to equal the number of shares of Integral Systems common stock subject to such out-of-the-money option multiplied by 0.9559, rounded up to the nearest whole share, and (ii) the per share exercise price under each such option adjusted by dividing the per share exercise price under such option by 0.9559, rounded up to the nearest whole cent. Each share of restricted stock granted under an Integral Systems equity plan or otherwise, whether vested or unvested, that is outstanding immediately prior to the completion of the Merger shall be cancelled and the holder thereof shall be entitled to receive an amount in cash equal to the product of the total number of restricted shares of Integral Systems common stock held by such holder, multiplied by $13.00, less the amount of any tax withholding. No fractional shares of Company common stock will be issued in the Merger. The Merger is intended to qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

        Completion of the Merger is subject to various customary conditions, including, among other things: (i) the approval of the stockholders of the Company and Integral Systems; (ii) subject to certain materiality exceptions, the accuracy of the representations and warranties made by each of the Company and Integral Systems and the compliance by each of the Company and Integral Systems with their respective obligations under the Merger Agreement; (iii) obtaining clearance under the Hart-Scott-Rodino Antitrust Improvements Act, as amended; and (iv) the declaration of the effectiveness by the Securities and Exchange Commission (the "SEC") of the Registration Statement on Form S-4 to be filed by the Company.

        The Merger Agreement contains customary representations, warranties and covenants, including covenants obligating the Company and Integral Systems to continue to conduct their respective businesses in the ordinary course and to cooperate on seeking regulatory approvals and providing access to each other's information. The Merger Agreement also contains a representation by the Company regarding the availability of funds to complete the transactions contemplated by the Merger Agreement, including the financing commitments described below, and a customary "no solicitation" provision pursuant to which, prior to the completion of the Merger, neither the Company nor Integral Systems is permitted to solicit or engage in discussions with any third party regarding another

---

acquisition proposal unless it has received an unsolicited proposal or offer that the recipient's board of directors determines is or could reasonably be expected to result in a "Superior Proposal".

        The Merger Agreement contains certain termination rights in favor of each of the Company and Integral Systems, including each party's right to terminate the Merger Agreement under certain circumstances in connection with the acceptance of a "Superior Proposal". In addition, the Merger Agreement provides that in connection with certain terminations of the Merger Agreement, depending on the circumstances surrounding the termination, one party may be required to pay the other a termination fee of $9,300,000.

        The foregoing summary of the Merger Agreement and the Merger does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and the terms of which are incorporated herein by reference.

        The Merger Agreement has been provided pursuant to applicable rules and regulations of the SEC in order to provide investors and stockholders with information regarding its terms. However, it is not intended to provide any other factual information about the Company, Integral Systems, their respective subsidiaries and affiliates, or any other party. In particular, the representations, warranties and covenants contained in the Merger Agreement have been made only for the purpose of the Merger Agreement and, as such, are intended solely for the benefit of the parties to the Merger Agreement. In many cases, these representations, warranties and covenants are subject to limitations agreed upon by the parties and are qualified by certain disclosures exchanged by the parties in connection with the execution of the Merger Agreement. Furthermore, many of the representations and warranties in the Merger Agreement are the result of a negotiated allocation of contractual risk among the parties and, taken in isolation, do not necessarily reflect facts about the Company, Integral Systems, their respective subsidiaries and affiliates or any other party. Likewise, any references to materiality contained in the representations and warranties may not correspond to concepts of materiality applicable to investors or stockholders. Finally, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement and these changes may not be fully reflected in the Company's public disclosures.

        AS A RESULT OF THE FOREGOING, INVESTORS AND STOCKHOLDERS ARE STRONGLY ENCOURAGED NOT TO RELY ON THE REPRESENTATIONS, WARRANTIES AND COVENANTS CONTAINED IN THE MERGER AGREEMENT, OR ON ANY DESCRIPTIONS THEREOF, AS ACCURATE CHARACTERIZATIONS OF THE STATE OF FACTS OR CONDITION OF THE COMPANY OR ANY OTHER PARTY. INVESTORS AND STOCKHOLDERS ARE LIKEWISE CAUTIONED THAT THEY ARE NOT THIRD-PARTY BENEFICIARIES UNDER THE MERGER AGREEMENT AND DO NOT HAVE ANY DIRECT RIGHTS OR REMEDIES PURSUANT TO THE MERGER AGREEMENT.

        In connection with the acquisition of Integral Systems, Kratos has been provided with firm commitments for a combination of bond and asset-based debt financing in an aggregate principal amount of up to $145 million by Jefferies Group, Inc. and Key Capital Corporation.

Kratos Voting Agreements with Key Integral Systems Stockholders

        Concurrently with the execution and delivery of the Merger Agreement, the directors and certain executive officers of Integral Systems (collectively, the "Key Integral Systems Stockholders") entered into voting agreements in favor of the Company (collectively, the "Kratos Voting Agreements"). Pursuant to the Kratos Voting Agreements, the Key Integral Systems Stockholders have agreed to vote, or cause to be voted, all shares of Integral Systems common stock beneficially owned by them in favor of the adoption of the Merger Agreement. In addition, the Key Integral Systems Stockholders have agreed to vote all such shares of Integral Systems common stock against any acquisition proposal related to Integral Systems or any other action involving Integral Systems that would in any manner interfere with or impede the Merger or the Merger Agreement.

---

        The Kratos Voting Agreements also provide that the Key Integral Systems Stockholders will not, among other things, sell, encumber, transfer or otherwise dispose of, or enter into any contract, option or other agreement with respect to the transfer of, any shares of Integral Systems common stock beneficially owned by them, or grant any proxies with respect to such shares. The Key Integral Systems Stockholders have also agreed not to take any actions that Integral Systems is prohibited from taking pursuant to the "no solicitation" provisions contained in the Merger Agreement.

        The Kratos Voting Agreements will terminate upon the earliest to occur of: (i) the termination of the Merger Agreement in accordance with its terms; (ii) the date on which the Merger becomes effective; and (iii) the date on which an amendment to the Merger Agreement is effected without the consent of the Key Integral Systems Stockholders that decreases the Merger Consideration or materially and adversely affects such Key Integral Systems Stockholders.

        The foregoing summary of the Kratos Voting Agreements and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the form of Kratos Voting Agreement, a copy of which is attached hereto as Exhibit 10.1 and the terms of which are incorporated herein by reference.

Forward-Looking Statements

        Certain statements in this Current Report on Form 8-K may constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements relate to a variety of matters, including but not limited to: the timing and anticipated completion of the proposed merger; and other statements that are not purely statements of historical fact. These forward-looking statements are made on the basis of the current beliefs, expectations and assumptions of the management of the Company and Integral Systems and are subject to significant risks and uncertainty. Investors are cautioned not to place undue reliance on any such forward-looking statements. All such forward-looking statements speak only as of the date they are made, and neither the Company nor Integral Systems undertakes any obligation to update or revise these statements, whether as a result of new information, future events or otherwise.

        Factors that could cause actual results to differ materially from the forward-looking statements contained herein include, but are not limited to: unexpected costs, charges or expenses resulting from the proposed merger; litigation or adverse judgments relating to the proposed merger; risks relating to the consummation of the contemplated merger, including the risk that the required stockholder approval might not be obtained in a timely manner or at all or that other closing conditions will not be satisfied; any difficulties associated with requests or directions from governmental authorities resulting from their reviews of the transaction; and any changes in general economic and/or industry-specific conditions. Additional factors that could cause actual results to differ materially from those described in the forward-looking statements are set forth in the Annual Report on Form 10-K of the Company for the year ended December 26, 2010, which was filed with the SEC on March 2, 2011, under the heading "Item 1A—Risk Factors" and in the Annual Report on Form 10-K of Integral Systems for the year ended September 24, 2010, which was filed with the SEC on December 8, 2010, under the heading "Item 1A—Risk Factors," and in subsequent reports on Forms 10-Q and 8-K and other filings made with the SEC by each of the Company and Integral Systems.

Important Merger Information and Additional Information and Where to Find It

        No statement in this Current Report on Form 8-K or in the attached exhibits constitutes an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval. In connection with the proposed merger, the Company and Integral Systems will file relevant materials with the SEC, including the filing by the Company of a Registration Statement on Form S-4 containing a joint proxy statement/prospectus. Investors are strongly urged to read the joint proxy statement/prospectus when it becomes available and other documents filed with the SEC by the Company and Integral Systems, because they will contain important information about the Company, Integral Systems and the proposed merger. The joint proxy statement/prospectus and other documents that will

        The Company, Integral Systems and their respective directors and certain of their executive officers may be considered participants in the solicitation of proxies in connection with the proposed merger. Information about the directors and executive officers of the Company is set forth in the Company's most recent definitive proxy statement, which was filed with the SEC on April 15, 2011. Information about the directors and executive officers of Integral Systems is set forth in Integral Systems' most recent definitive proxy statement, which was filed with the SEC on January 12, 2011. Certain directors and executive officers of the Company and Integral Systems may have direct or indirect interests in the proposed merger due to securities holdings, indemnification arrangements, vesting of options or rights to severance payments if their employment is terminated following the proposed merger.

        Section 2.1    Conversion of Securities.    At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent, Merger Sub or the holders of any of the following securities:

        (a)   Each share of common stock, par value $0.01 per share, of the Company (such shares, collectively, the "Company Shares") issued and outstanding immediately prior to the Effective Time, other than any Company Shares to be canceled pursuant to Section 2.1(b) and any Dissenting Shares, shall be converted into the right to receive (i) $5.00 in cash, without interest and (ii) 0.588 Parent Shares (such Parent Shares and cash, together with any cash in lieu of fractional Parent Shares to be paid pursuant to Section 2.5, the "Merger Consideration"), payable to the holder thereof, without interest, less any required withholding Taxes, and further subject to payment by Parent of cash in lieu of any fractional Parent Share pursuant to Section 2.5. All Company Shares that have been converted into the right to receive Merger Consideration as set forth in this Section 2.1(a) shall be automatically cancelled and shall cease to exist.

---

shall cease to exist without any conversion thereof, and no payment or distribution shall be made with respect thereto.

        (c)   Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time will remain outstanding as a share of common stock of the Surviving Corporation.

        (d)   If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of the Company or Parent, or securities convertible into or exchangeable into or exercisable for shares of such capital stock, shall occur as a result of any reclassification, recapitalization, stock split (including a reverse stock split) or subdivision or combination, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period (excluding, in each case, normal quarterly cash dividends), merger or other similar transaction, the Merger Consideration shall be equitably adjusted, without duplication, to reflect such change; provided, that nothing in this Section 2.1(d) shall be construed to permit the Company or Parent to take any action with respect to its securities that is prohibited by the terms of this Agreement.

        Section 2.2    Treatment of Options and Restricted Shares.    

        (a)   Except with respect to options under the Company ESPP (as defined below), the Company shall take all such action as may be required to fully vest each option or similar right (each, a "Company Stock Option") granted under any stock option, stock purchase or equity compensation plan, arrangement or agreement of the Company (the "Company Equity Plans") as of immediately prior to the Effective Time. If the holder so elects in writing, each In-The-Money Company Option shall be canceled at the Effective Time, in exchange for a payment by the Surviving Corporation, in cash, equal to the product of (i) the total number of Company Shares subject to such In-The-Money Option, multiplied by (ii) the aggregate value of the excess, if any, of (A) the Per Share Amount over (B) the exercise price per Company Share subject to such In-The-Money Option (with the aggregate amount of such payment to the holder to be rounded to the nearest cent), less the amount of any required withholding. To the extent that a holder of an In-The-Money Option does not elect (in a form reasonably acceptable to Parent) that a particular Company Stock Option be treated in the manner described in the prior sentence, that Company Stock Option shall instead be treated as an "Out-Of-The-Money Option" for all purposes.

        (b)   At the Effective Time, all rights with respect to Company Shares under each Out-Of-The-Money Option shall be converted into and become rights with respect to Parent Common Stock, and Parent shall assume each such Out-Of-The-Money Option. From and after the Effective Time, (i) each Out-Of-The-Money Option assumed by Parent may be exercised solely for shares of Parent Common Stock, (ii) the number of shares of Parent Common Stock subject to each such Out-Of-The-Money Option shall be equal to the number of Company Shares subject to such Out-Of-The-Money Option immediately prior to the Effective Time multiplied by 0.9559, rounding up to the nearest whole share, (iii) the per share exercise price under each such Out-Of-The-Money Option shall be adjusted by dividing the per share exercise price under such Out-Of-The-Money Option by 0.9559 and rounding up to the nearest cent, and (iv) any restriction on the exercise of any such Out-Of-The-Money Option shall continue in full force and effect and the term, exercisability, and other provisions of such Out-Of-The-Money Option shall otherwise remain unchanged (except that such Out-Of-The Money Option shall be fully vested pursuant to the first sentence of Section 2.2(a)); provided, however, that each Out-Of-The-Money Option assumed by Parent in accordance with this Section 2.2(b) shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, reverse stock split, reclassification, recapitalization or other similar transaction effected subsequent to the Effective Time.

        (c)   At the Effective Time, each share of restricted stock granted under a Company Equity Plan or otherwise (each, a "Company Restricted Share"), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be cancelled and the holder thereof shall be entitled to receive an amount in cash, without interest, equal to the product of (i) the number of Company Restricted Shares held by such holder, multiplied by (ii) the Per Share Amount (with the aggregate amount of such payment to the holder to be rounded to the nearest cent), less the amount of any required withholding.

        (d)   As soon as practicable following the date of this Agreement, the Company Board or the compensation committee of the Company Board will adopt such resolutions and take such other actions as may be required to provide that with respect to the Company's Employee Stock Purchase Plan (as amended from time to time prior to the date hereof, the "Company ESPP"): (i) participants in the Company ESPP may not alter their payroll deductions from those in effect on the date of this Agreement (other than to discontinue their participation in the Company ESPP); (ii) no offering period will be commenced after the date of this Agreement (it being understood that any offering period in effect on the date hereof may continue in accordance with its terms, subject to the next clause); (iii) the Company ESPP and all offering periods then in effect shall be terminated effective immediately prior to the Effective Time; and (iv) the amount of the accumulated contributions of each participant under the Company ESPP as of immediately prior to the Effective Time shall be refunded to such participant as promptly as practicable following the Effective Time, without interest.

        (e)   Prior to the Effective Time, the Company shall take all actions reasonably necessary to effect the measures contemplated by this Section 2.2, including but not limited to adoption of any resolutions, interpretations, plan amendments, offering to enter into the elections contemplated by Section 2.2(a) within a reasonable period of time prior to the Effective Date, seeking Company Board approval and/or seeking any consents, and to ensure that, on and after the Effective Time, no holder of an In-The-Money Option or Company Restricted Stock has any further rights with respect thereto (other than to receive the payments provided for in this Section 2.2) and that no holder of an Out-Of-The-Money Option has any further rights with respect thereto (other than the rights provided for in this Section 2.2) and that no Company ESPP participant has any further rights with respect thereto (other than the rights provided for in this Section 2.2).

        (f)    The Company shall take all actions necessary to ensure that, as of the Effective Time, (i) the Company Equity Plans shall terminate and (ii) no holder of Company Stock Options, Company Restricted Shares and no participant in any Company Equity Plan or any other employee incentive or benefit plan, program or arrangement or any non-employee director plan maintained by the Company shall have any rights to acquire, or other rights in respect of, the capital stock of the Company, the Surviving Corporation or any of their subsidiaries, except the conversion rights contemplated by Section 2.1 or this Section 2.2.

        (g)   Prior to the Effective Time, the Company shall deliver all notices required by the Company Equity Plans or contemplated by this Section 2.2 (which notices shall have been approved by Parent, in its reasonable discretion) to each holder of Company Stock Options and Company Restricted Shares, setting forth each holder's or participant's rights pursuant to the applicable Company Equity Plan and this Section 2.2 stating that such Company Stock Options or Company Restricted Shares, as applicable, shall be treated in the manner set forth in this Section 2.2.

        Section 2.3    Exchange and Payment.    

        (a)   Prior to the Effective Time, Merger Sub shall enter into an agreement with the Company's transfer agent to act as agent for the stockholders of the Company in connection with the Merger (the "Paying Agent") to receive the Merger Consideration to which stockholders of the Company shall become entitled pursuant to this Article II. Promptly, and in no event later than 1

Business Day after the Effective Time, Parent shall deposit (or cause to be deposited) with the Paying Agent (i) stock certificates representing Parent Shares and (ii) cash, in each case in an aggregate amount equal to the number of Parent Shares and amount of cash into which Company Shares have been converted in accordance with Section 2.1(a). Prior to the Effective Time, Parent will provide to the Company written certification from the commitment parties under the Commitment Letters that they will release funds after the Effective Time. In addition, Parent shall deposit with the Paying Agent, as necessary from time to time at or after the Effective Time, cash in lieu of any fractional shares payable pursuant to Section 2.5 and any dividends or other distributions payable pursuant to Section 2.6. All Parent Shares, cash and dividends and distributions deposited with the Paying Agent pursuant to this Section 2.3(a) shall hereinafter be referred to as the "Payment Fund". The Payment Fund shall not be used for any purpose other than to fund payments due pursuant to this Article II, except as provided in this Agreement.

        (b)   Promptly after the Effective Time and in any event not later than the fifth Business Day following the Effective Time, the Surviving Corporation shall cause to be mailed to each holder of record of an outstanding certificate or outstanding certificates that immediately prior to the Effective Time represented outstanding Company Shares ("Company Certificates") that were converted into the right to receive the Merger Consideration with respect thereto pursuant to Section 2.1(a), (A) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates held by such person shall pass, only upon proper delivery of the Company Certificates to the Paying Agent and shall be in customary form and contain such other provisions as Parent or the Paying Agent may reasonably specify) and (B) instructions for use in effecting the surrender of Company Certificates in exchange for the Merger Consideration payable with respect thereto pursuant to Section 2.2. Upon surrender of a Company Certificate to the Paying Agent, together with such letter of transmittal, duly completed and validly executed, and such other documents as the Paying Agent may reasonably require, the holder of such Company Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Company Share formerly represented by such Company Certificate (subject to deduction for any required withholding Tax), and such Company Certificate shall forthwith be canceled. Promptly following the Effective Time (but in no event later than 5 Business Days following the Effective Time), to the extent consistent with the Paying Agent's standard procedures, Parent shall cause the Paying Agent to issue and deliver the Merger Consideration to holders of uncertificated Company Shares represented by book-entry (the "Book-Entry Company Shares") (either directly or through the Depository Trust Company), without each holder of Book-Entry Company Shares being required to deliver a Company Certificate or any executed letter of transmittal to the Paying Agent, and such Book-Entry Company Shares shall forthwith be cancelled. No interest will be paid or accrued on any Merger Consideration payable to holders of Company Certificates or Book-Entry Company Shares. In the event of a transfer of ownership of Company Shares that is not registered in the transfer records of the Company, the Merger Consideration may be issued to a transferee if the Company Certificate representing such Company Shares is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 2.3, each Company Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration or the right to demand to be paid the "fair value" of the shares represented thereby as contemplated by Section 2.7, as applicable.

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

Merger Consideration payable upon due surrender of their Company Certificates and Book-Entry Company Shares. The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, in connection with the exchange of Company Shares for the Merger Consideration.

        (d)   All cash paid and Parent Shares issued upon the surrender for exchange of Company Certificates or Book-Entry Company Shares in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the Company Shares, formerly represented by such Company Certificates or Book-Entry Company Shares. After the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Company Shares that were outstanding prior to the Effective Time. If, after the Effective Time, Company Certificates are presented to the Surviving Corporation for transfer or transfer is sought for Book-Entry Company Shares, such Company Certificates or Book-Entry Company Shares shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth in, this Article II.

        (e)   The Paying Agent shall invest the cash included in the Payment Fund as directed by Parent on a daily basis; provided that (i) no such investment or losses thereon shall affect the Merger Consideration payable to the holders of Company Shares and following any losses Parent shall promptly provide additional funds to the Paying Agent for the benefit of the stockholders of the Company in the amount of any such losses and (ii) such investments shall be in short-term obligations of the United States of America with maturities of no more than 30 days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America. Any interest or income produced by such investments will be payable to the Surviving Corporation or Parent, as Parent directs.

        (f)    None of Parent, the Company, the Surviving Corporation or the Paying Agent or any other person shall be liable to any person in respect of Parent Shares, any dividends or distributions with respect thereto, any cash in lieu of fractional shares or any cash from the Payment Fund, in each case properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

        (g)   In the event that any Company Certificate shall have been lost, stolen or destroyed, upon the holder's compliance with the replacement requirements established by the Paying Agent, including, if necessary, the posting by the holder of a bond in a reasonable and customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to the Company Certificate, the Paying Agent will deliver in exchange for the lost, stolen or destroyed Company Certificate the applicable Merger Consideration payable in respect of the Company Shares represented by such Company Certificate pursuant to this Article II.

        (h)   Any portion of the Merger Consideration made available to the Paying Agent pursuant to Section 2.3(a) to pay for Company Shares for which appraisal rights have been perfected as described in Section 2.7 shall be returned to Parent, upon demand.

        Section 2.4    Withholding Rights.    Notwithstanding anything in this Agreement to the contrary, Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Company Shares, Company Stock Options, Company Restricted Shares or otherwise pursuant to this Agreement any amount as may be required to be deducted and withheld with respect to the making of such payment under applicable Tax laws. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

        Section 2.5    Fractional Shares.    No certificates or scrip representing a fractional Parent Share shall be issued upon the surrender for exchange of Company Certificates or Book-Entry Company Shares evidencing Company Shares, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. In lieu thereof, upon surrender of the applicable Company Certificates or Book-Entry Company Shares, Parent shall pay each holder of Company Shares an amount in cash equal to the product obtained by multiplying (a) the fractional share interest in Parent to which such holder (after taking into account all Company Shares held at the Effective Time) would otherwise be entitled, by (b) the Average Parent Trading Price.

        Section 2.6    Distributions With Respect to Unexchanged Company Shares.    No dividends or other distributions with respect to Parent Shares issuable with respect to Company Shares shall be paid to the holder of any unsurrendered Company Certificates or Book-Entry Company Shares until those Company Certificates or Book-Entry Company Shares are surrendered as provided in this Article II. Upon surrender, there shall be issued and/or paid to the holder of the Parent Shares issued in exchange therefor, without interest, (a) at the time of surrender, the dividends or other distributions payable with respect to those Parent Shares with a record date on or after the date of the Effective Time and a payment date on or prior to the date of this surrender and not previously paid and (b) at the appropriate payment date, the dividends or other distributions payable with respect to those Parent Shares with a record date on or after the date of the Effective Time but with a payment date subsequent to surrender.

        Section 2.7    Appraisal Rights.    

        (a)   So long as the Company Common Stock is listed on the Global Select Market of NASDAQ (i) on the record date for the determination of stockholders entitled to vote on the Merger with respect to mergers other than mergers pursuant to Section 3-106 of the MGCL or (ii) the date notice is given or waived under Section 3-106 of the MGCL in connection with a merger of a ninety percent (90%) owned subsidiary with or into its parent as the case may be (as applicable, the "Appraisal Date"), no stockholder of the Company shall have any rights under Title 3, Subtitle 2 of the MGCL as a result of the transactions contemplated by this Agreement.

        (b)   If the Company Common Stock is not listed on the Global Select Market of NASDAQ on the Appraisal Date, Company Shares that are issued and outstanding immediately prior to the Effective Time and that are held by stockholders who have not voted in favor of or consented to the Merger and shall have delivered a written demand for appraisal of such Company Shares in the time and manner provided in Section 3-203 of the MGCL and shall not have failed to perfect or shall not have effectively withdrawn or lost their rights to appraisal and payment under the MGCL (the "Dissenting Shares") shall not be converted into the right to receive the Merger Consideration, but shall be entitled to receive the consideration as shall be determined pursuant to Title 3, Subtitle 2 of the MGCL; provided, however, that if such holder shall have failed to perfect or shall have effectively withdrawn or lost his, her or its right to appraisal and payment under the MGCL, such holder's Company Shares shall thereupon be deemed to have been converted, at the Effective Time, into the right to receive the Merger Consideration set forth in Section 2.1(a), without any interest thereon.

        (c)   The Company shall give Parent (i) prompt notice of any written objection to the transactions contemplated by this Agreement or any demands for appraisal pursuant to Section 3-203 of the MGCL received by the Company, withdrawals of such demands, and any other instruments served pursuant to the MGCL and received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the MGCL.

of this Section 5.7(a). The Company acknowledges and agrees that any violation of the restrictions set forth in the preceding sentence by any Representative of the Company or any of its subsidiaries shall be deemed to constitute a breach of this Section 5.7(a) by the Company.

        (c)   Notwithstanding anything to the contrary in Sections 5.7(a) or (b), prior to the receipt of the Company Stockholder Approval, if the Company receives an unsolicited Company Alternative Proposal which did not result from or arise in connection with a breach of Section 5.7(a) and the Company Board determines, in good faith, after consultation with its outside counsel and financial advisors, that such Company Alternative Proposal is or could reasonably be expected to lead to a Company Superior Proposal and the Company Board, or any committee thereof, determines in good faith, after consultation with outside legal counsel, that failure to take such action could reasonably be expected to be a breach of the directors' duties under applicable Law, the Company may (i) furnish non-public information with respect to the Company and its subsidiaries to the person making such Company Alternative Proposal and its Representatives pursuant to a confidentiality agreement on terms substantially similar to those contained in the Confidentiality Agreement (except for such changes specifically necessary in order for the Company to be able to comply with its obligations under this Agreement and it being understood that the Company may enter into a confidentiality agreement without a standstill provision) and (ii) participate in discussions or negotiations with such person and its Representatives regarding such Company Alternative Proposal; provided, however, that the Company shall concurrently therewith provide or make available to Parent any material non-public information concerning the Company or any of its subsidiaries that is provided to the person making such Company Alternative Proposal or its Representatives which was not previously provided or made available to Parent.

Notwithstanding the foregoing, if, prior to receipt of the Company Stockholder Approval, the Company Board determines in good faith, after consultation with outside counsel, that failure to effect a Company Change of Recommendation could reasonably be expected to be a breach of their duties as directors under applicable Law, the Company Board or any committee thereof may effect a Company Change of Recommendation in response to (1) a Company Superior Proposal or (2) any material event, development, circumstance, occurrence or change in circumstances or facts not related to a Company Alternative Proposal that was not known to the Company Board as of the date of this Agreement (a "Company Intervening Event"); provided, however, that the Company shall not be entitled to effect a Company Change of Recommendation unless (A) the Company shall have first provided prior written notice (a "Proposal Notice") to Parent that it is prepared to make a Company Change of Recommendation which notice shall, if the basis for the proposed action by the Company Board is related to a Company Superior Proposal, contain a description of the material terms and conditions of such Company Superior Proposal, including a copy of the definitive agreement in the form to be entered into (if any), or, if the basis for the proposed action by the Company Board is related to a Company Intervening Event, contain a description of the event, development, circumstance, occurrence or change in circumstances or facts giving rise to such proposed action and (B) Parent does not make, within

37

three Business Days after the receipt of such notice, a proposal (a "Subsequent Parent Proposal") that would, in the good faith judgment of the Company Board (after consultation with outside counsel and, in the case of a Company Superior Proposal, the Company's financial advisor), cause such Company Intervening Event to no longer form the basis for the Company Board to effect a Company Change of Recommendation or cause the offer previously constituting a Company Superior Proposal to no longer constitute a Company Superior Proposal, as the case may be. If Parent has made a Subsequent Parent Proposal and there is any material change made to the financial terms or to other material terms of the Company Superior Proposal prior to the Company's making a Company Change of Recommendation or terminating this Agreement pursuant to Section 7.1(c)(iii), the Company shall provide to Parent a new Proposal Notice and Parent shall have a period of 48 hours after the receipt of such new Proposal Notice to make another proposal, which will be otherwise subject to the provisions of this Section 5.7(d).

        (e)   The Company promptly (and in any event within 48 hours) shall advise Parent orally and in writing of (i) any written Company Alternative Proposal, (ii) any written request for non-public information relating to the Company or its subsidiaries, other than requests for information not reasonably expected to be related to a Company Alternative Proposal, and (iii) any written inquiry or request for discussion or negotiation regarding a Company Alternative Proposal, including in each case the identity of the person making any such Company Alternative Proposal or indication or inquiry and the material terms of any such Company Alternative Proposal or indication or inquiry. The Company shall keep Parent fully informed on a current basis of the status of, and any material changes or proposed material changes to, the terms of any such Company Alternative Proposal and the status of discussions and negotiations thereto.

        (f)    Nothing contained in this Agreement shall prohibit the Company or the Company Board from (i) disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or (ii) making any required disclosure to the Company's stockholders if, in the good faith judgment of the Company Board, after consultation with its outside legal counsel, the failure to disclose such information would reasonably be expected to violate the obligations of the Company's directors under applicable Law.

        (g)   As used in this Agreement, "Company Alternative Proposal" shall mean any inquiry, proposal or offer from any person or group of persons other than Parent or one of its subsidiaries for (i) a merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving an acquisition of the Company (or any subsidiary or subsidiaries of the Company whose business constitutes 20% or more of the net revenues, net income or assets of the Company and its subsidiaries, taken as a whole) or (ii) the acquisition in any manner, directly or indirectly, of over 20% of the equity securities or consolidated total assets of the Company and its subsidiaries, in each case other than the Merger and the LLC Merger.

        (h)   As used in this Agreement, "Company Superior Proposal" shall mean any Company Alternative Proposal on terms which the Company Board determines in good faith, after consultation with the Company's outside legal counsel and financial advisors, and taking into consideration, among other things, all of the terms, conditions, impact, timing, likelihood of consummation and all legal, financial, regulatory and other aspects of such Company Alternative Proposal and this Agreement, would result in a transaction that is more favorable to the holders of Company Shares from a financial point of view than the transactions provided for in this Agreement; provided that for purposes of the definition of "Company Superior Proposal," the references to "20%" in the definition of Company Alternative Proposal shall be deemed to be references to "50%").

Parent acknowledges and agrees that any violation of the restrictions set forth in the preceding sentence by any Representative of Parent or any of its subsidiaries shall be deemed to constitute a breach of this Section 5.8(a) by Parent.

        (b)   Parent shall, shall cause each of its subsidiaries to, and shall direct each of its Representatives to, immediately cease any solicitations, discussions or negotiations with any person (other than the parties hereto) that has made or indicated an intention to make a Parent Alternative Proposal, in each case that exist as of the date hereof.

        (c)   Notwithstanding anything to the contrary in Sections 5.8(a) or (b), prior to the receipt of the Parent Stockholder Approval, if Parent receives an unsolicited Parent Alternative Proposal which did not result from or arise in connection with a breach of Section 5.8(a) and the Parent Board determines, in good faith, after consultation with its outside counsel and financial advisors, that such Parent Alternative Proposal is or could reasonably be expected to lead to a Parent Superior Proposal (without regard to the first proviso in the definition thereof) and the Parent Board, or any committee thereof, determines in good faith, after consultation with outside legal counsel, that failure to take such action could reasonably be expected to be a breach of the directors' duties under applicable Law, Parent may (i) furnish non-public information with respect to Parent and its subsidiaries to the person making such Parent Alternative Proposal and its Representatives pursuant to a confidentiality agreement on terms substantially similar to those contained in the Confidentiality Agreement (except for such changes specifically necessary in order for Parent to be able to comply with its obligations under this Agreement and it being understood that Parent may enter into a confidentiality agreement without a standstill provision) and (ii) participate in discussions or negotiations with such person and its Representatives regarding such Parent Alternative Proposal; provided, however, that Parent shall concurrently therewith provide or make available to the Company any material non-public information concerning Parent or any of its subsidiaries that is provided to the person making such Parent Alternative Proposal or its Representatives which was not previously provided or made available to the Company.

        (d)   Neither the Parent Board nor any committee thereof shall (i) withdraw or modify in a manner adverse to the Company, or publicly propose to withdraw or modify in a manner adverse to the Company, the Parent Recommendation or (ii) approve or recommend, or publicly propose to approve, endorse or recommend, any Parent Alternative Proposal (any action described in clauses (i) and (ii) being referred to as a "Parent Change of Recommendation"). Notwithstanding the foregoing, if, prior to receipt of the Parent Stockholder Approval, the Parent Board determines in good faith, after consultation with outside counsel, that failure to effect a Parent Change of

39

---

Recommendation could reasonably be expected to be a breach of their duties as directors under applicable Law, the Parent Board or any committee thereof may effect a Parent Change of Recommendation in response to (1) a Parent Superior Proposal or (2) any material event, development, circumstance, occurrence or change in circumstances or facts not related to a Parent Superior Proposal that was not known to the Parent Board as of the date of this Agreement (a "Parent Intervening Event"); provided, however, that Parent shall not be entitled to effect a Parent Change of Recommendation unless (A) Parent shall have first provided a Proposal Notice to the Company that it is prepared to make a Parent Change of Recommendation which notice shall contain a description of the event, development, circumstance, occurrence or change in circumstances or facts giving rise to such proposed action, including the material terms of a Parent Superior Proposal, if any, and (B) the Company does not make, within three Business Days after the receipt of such notice, a proposal (a "Subsequent Company Proposal") that would, in the good faith judgment of the Parent Board (after consultation with outside counsel and, in the case of a Parent Superior Proposal, Parent's financial advisor), cause such Parent Intervening Event or Parent Superior Proposal to no longer form a basis for the Parent Board to effect a Parent Change of Recommendation under this Section 5.8(d). Any material changes with respect to such event, development, circumstance, occurrence or change in circumstances or facts mentioned above occurring prior to Parent's effecting a Parent Change of Recommendation shall require Parent to provide to the Company a new Proposal Notice and the Company shall have a period of 48 hours after the receipt of such new Proposal Notice to make another proposal, which will be otherwise subject to the provisions of this Section 5.8(d).

        (e)   Parent promptly (and in any event within 48 hours) shall advise the Company orally and in writing of (i) any written Parent Alternative Proposal, (ii) any written request for non-public information relating to Parent or its subsidiaries, other than requests for information not reasonably expected to be related to a Parent Alternative Proposal, and (iii) any written inquiry or request for discussion or negotiation regarding a Parent Alternative Proposal, including in each case the identity of the person making any such Parent Alternative Proposal or indication or inquiry and the material terms of any such Parent Alternative Proposal or indication or inquiry.

would result in a transaction that is more favorable to the holders of Parent Shares from a financial point of view than the transactions provided for in this Agreement; provided, however, that such Parent Alternative Proposal is conditioned, expressly by its terms or otherwise, on the Merger not being consummated in accordance with the terms of this Agreement; provided that for purposes of the definition of "Parent Superior Proposal," the references to "20%" in the definition of Parent Alternative Proposal shall be deemed to be references to "50%").

        (b)   As of and after the Effective Time, Parent will, or will cause the Surviving Corporation or the Surviving Company to, give Company Employees full credit for purposes of eligibility and vesting and benefit accruals (but only for the purpose of determining vacation and severance entitlements), under any employee compensation and incentive plans, benefit (including vacation and severance) plans, programs, policies and arrangements maintained for the benefit of Company Employees as of and after the Effective Time by Parent, its subsidiaries or the Surviving Corporation for the Company Employees' service with the Company, its subsidiaries and their predecessor entities (each, a "Parent Plan") to the same extent recognized by the Company immediately prior to the Effective Time.

harmless, to the fullest extent to which such persons are entitled to be indemnified and held harmless under the MGCL as of the date of this Agreement, each present (as of the Effective Time) and former officer, director or employee of the Company and its subsidiaries (the "Indemnified Parties"), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys' fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to (i) the fact that an Indemnified Party is or was an officer, director, employee, fiduciary or agent of the Company or any of its subsidiaries or is or was serving at the request of the Company or any of its subsidiaries as a director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise or non-profit entity or (ii) matters existing or occurring at or prior to the Effective Time (including this Agreement and the transactions and actions contemplated hereby), whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under applicable Law. In the event of any such claim, action, suit, proceeding or investigation, (x) each Indemnified Party will be entitled to advancement of expenses incurred in the defense of any claim, action, suit, proceeding or investigation from the Surviving Corporation and the Surviving Company to the fullest extent to which such Indemnified Party is entitled to such payment as of the date of this Agreement; provided that any person to whom expenses are advanced provides an undertaking, if and only to the extent required by the MGCL or the Charter or Bylaws, to repay such advances if it is ultimately determined that such person is not entitled to indemnification, (y) neither Parent, the Surviving Corporation nor the Surviving Company shall settle, compromise or consent to the entry of any judgment in any proceeding or threatened action, suit, proceeding, investigation or claim (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, proceeding, investigation or claim or such Indemnified Party otherwise consents, and (z) the Surviving Corporation or the Surviving Company shall cooperate in the defense of any such matter.

        (b)   All rights to indemnification, expenses and exculpation existing in favor of the former or present directors and officers for their acts and omissions occurring prior to the Effective Time, as provided in the Charter and Bylaws as in effect on the date of this Agreement, shall survive the Merger and the LLC Merger and shall be observed by Parent, the Surviving Corporation and the Surviving Company to the fullest extent permitted by Law for a period of 6 years from the Effective Time.

        (c)   Parent shall maintain, or shall cause the Surviving Corporation or the Surviving Company to maintain, at no expense to the beneficiaries, in effect for 6 years from the Effective Time the current policies of the directors' and officers' liability insurance maintained by the Company (the "Existing D&O Policies") (provided that Parent, the Surviving Corporation or the Surviving Company may substitute therefor policies of at least the same coverage containing terms and conditions which are not less advantageous to any beneficiary thereof) with respect to matters existing or occurring at or prior to the Effective Time; provided, that in no event shall the aggregate costs of such insurance policies exceed in any one year during such 6 year period 300% of the current aggregate annual premiums paid by the Company for such purpose (which aggregate annual premiums with respect to such period are hereby represented and warranted by the Company to be in the amount set forth in Section 5.10(c) of the Company Disclosure Schedule), it being understood that Parent, the Surviving Corporation or the Surviving Company shall nevertheless be obligated to provide such coverage, with respect to each year during such 6 year period, as may be obtained for such 300% annual amount. Parent may, if requested by the Company prior to Closing, cause to be acquired a 6 year tail policy for the Indemnified Parties currently covered by the Existing D&O Policies that is consistent with the first sentence of this

42

---

paragraph (c). Any such policy shall be prepaid at the Effective Time and shall be non-cancelable. Parent agrees to honor and perform under, and to cause the Surviving Corporation and the Surviving Company to honor and perform under, all indemnification agreements with Indemnified Parties entered into by the Company or any of its subsidiaries prior to the date of this Agreement.

        (d)   Notwithstanding anything herein to the contrary, if any claim, action, suit, proceeding or investigation (whether arising before, at or after the Effective Time) is made against any Indemnified Party on or prior to the sixth anniversary of the Effective Time, the provisions and benefits of this Section 5.10 shall continue in full effect until the final disposition of such claim, action, suit, proceeding or investigation.

        (e)   This covenant is intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives. The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to Law, contract or otherwise.

        (f)    In the event that the Surviving Corporation, the Surviving Company or Parent or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or a majority of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation, the Surviving Company or Parent, as the case may be, shall succeed to the obligations set forth in Section 5.9 and this Section 5.10.

Nothing in this Voting Agreement is intended to confer on any Person (other than Parent and its successors and assigns) any rights or remedies of any nature.

        6.9    Specific Performance.    The parties agree that irreparable damage would occur in the event that any of the provisions of this Voting Agreement or the Proxy were not performed in accordance with its specific terms or were otherwise breached.

        6.14    Headings.    The descriptive headings contained in this Voting Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Voting Agreement.

        6.15    Waiver.    Subject to the remainder of this Section 6.15, at any time prior to the Expiration Date, any party hereto may: (a) extend the time for the performance of any of the obligations or other acts of the other parties to this Voting Agreement; (b) waive any inaccuracy in or breach of any representation, warranty, covenant or obligation of the other party in this Voting Agreement or in any document delivered pursuant to this Voting Agreement; and (c) waive compliance with any covenant, obligation or condition for the benefit of such party contained in this Voting Agreement. No failure on the part of Parent to exercise any power, right, privilege or remedy under this Voting Agreement, and no delay on the part of Parent in exercising any power, right, privilege or remedy under this Voting Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. Parent shall not be deemed to have waived any claim available to Parent arising out of this Voting Agreement, or any power, right, privilege or remedy of Parent under this Voting Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of Parent; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

        6.16    Independence of Obligations.    The covenants and obligations of Stockholder set forth in this Voting Agreement shall be construed as independent of any other contract between Stockholder, on the one hand, and the Company or Parent, on the other. The existence of any claim or cause of action by Stockholder against the Company or Parent shall not constitute a defense to the enforcement of any of such covenants or obligations against Stockholder. Nothing in this Voting Agreement shall limit any of the rights or remedies of Parent under the Merger Agreement, or any of the rights or remedies of Parent or any of the obligations of Stockholder under any agreement between Stockholder and Parent or any certificate or instrument executed by Stockholder in favor of Parent; and nothing in the Merger Agreement or in any other such agreement, certificate or instrument, shall limit any of the rights or remedies of Parent or any of the obligations of Stockholder under this Voting Agreement.

        6.17    Other Capacities.    Notwithstanding any provision of this Voting Agreement to the contrary, nothing in this Voting Agreement shall limit or restrict Stockholder from acting in good faith in Stockholder's capacity as a director or officer of the Company (it being understood that this Voting Agreement shall apply to Stockholder solely in Stockholder's capacity as a stockholder of the Company).

        (b)   The parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting party shall not be applied in the construction or interpretation of this Voting Agreement.

        (c)   As used in this Voting Agreement, the words "include" and "including," and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words "without limitation."

        (d)   Except as otherwise indicated, all references in this Voting Agreement to "Sections" and "Exhibits" are intended to refer to Sections of this Voting Agreement and Exhibits to this Voting Agreement.

IRREVOCABLE PROXY

        The undersigned stockholder (the "Stockholder") of Integral Systems, Inc., a Maryland corporation (the "Company"), hereby irrevocably (to the fullest extent permitted by law) appoints and constitutes Kratos Defense & Security Solutions, Inc., a Delaware corporation ("Parent"), and Eric DeMarco and Deanna Lund, solely in their capacities as executive officers of Parent, and each of them, the attorneys and proxies of the Stockholder, with full power of substitution and resubstitution, to the full extent of the Stockholder's rights with respect to the outstanding shares of capital stock of the Company owned of record by the Stockholder as of the date of this proxy, which shares are specified on the final page of this proxy, and any and all other shares or securities issued or issuable in respect thereof on or after the date hereof and prior to the date this proxy terminates. (The shares of the capital stock of the Company and other securities referred to in the immediately preceding sentence are referred to as the "Shares.") Upon the execution of this proxy, all prior proxies given by the Stockholder with respect to any of the Shares are hereby revoked, and the Stockholder agrees that no subsequent proxies inconsistent with this Proxy will be given with respect to any of the Shares.

        This proxy is irrevocable, is coupled with an interest and is granted in connection with, and as security for, the Voting Agreement, dated as of the date hereof, between Parent and the Stockholder (the "Voting Agreement"), and is granted in consideration of Parent entering into the Agreement and Plan of Merger, dated as of the date hereof, among Parent, Iris Merger Sub Inc., a wholly-owned subsidiary of Parent, Iris Acquisition Sub LLC, a wholly-owned subsidiary of Parent, and the Company (the "Merger Agreement"). This proxy will terminate on the Expiration Date (as defined in the Voting Agreement). Capitalized terms used but not otherwise defined in this Irrevocable Proxy have the meanings assigned to such terms in the Merger Agreement.

        Prior to the Expiration Date, the attorneys and proxies named above will be empowered, and may exercise this proxy, to vote any Shares owned by the undersigned, at any meeting of the stockholders of the Company, however called, or at any adjournment or postponement thereof and on every action or approval by written consent of the stockholders of the Company:

        (a)   in favor of the approval of the Merger Agreement and the Merger;

        (b)   against any Company Alternative Proposal; and

        (c)   against any other action, agreement, proposal or transaction involving the Company or any of its subsidiaries which other action, agreement, proposal or transaction would compete with, interfere with, impede, frustrate, prevent, burden or nullify the Merger or the Merger Agreement.

        The Stockholder may vote the Shares on all other matters not referred to in this proxy, and the attorneys and proxies named above may not exercise this proxy with respect to such other matters.

        This proxy shall be binding upon the heirs, estate, executors, personal representatives, successors and assigns of the Stockholder (including any transferee of any of the Shares).

        Any term or provision of this proxy that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this proxy or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. Upon such determination that any term or provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this proxy so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.
