WHEREAS, the board of directors of Parent has approved and deems advisable and in the best interests of its stockholders this Agreement and the Merger (as defined below), upon the terms and subject to the conditions set forth in this Agreement;

WHEREAS, the respective boards of directors of each of U.S. Parent, Merger Sub and the Company have determined that it is advisable, fair to (in the case of the Company) and in the best interests of their respective stockholders for Parent to acquire the Company pursuant to a merger (the “Merger”) of Merger Sub with and into the Company pursuant to the DGCL upon the terms and subject to the conditions set forth in this Agreement, pursuant to which each outstanding share of common stock, par value $0.01 per share (the “Common Stock”), of the Company shall be converted into the right to receive cash, as set forth herein, all upon the terms and subject to the conditions of this Agreement;

WHEREAS, the board of directors of the Company (the “Company Board of Directors”) has (i) determined that this Agreement, the Merger and the other transactions contemplated hereby, taken together, are fair to, advisable and in the best interests of the Company and its stockholders (the “Company Stockholders”) and (ii) adopted resolutions approving this Agreement and the transactions contemplated hereby, including the Merger, declaring its advisability and recommending the adoption by the Company Stockholders of this Agreement, the Merger and the other transactions contemplated hereby; and

WHEREAS, the respective boards of directors of each of U.S. Parent and Merger Sub have (i) determined that this Agreement, the Merger and the other transactions contemplated hereby, taken together, are advisable and in the best interests of Merger Sub and U.S. Parent and (ii) adopted resolutions approving this Agreement and the transactions contemplated hereby, including the Merger, declaring its advisability and, in the case of the board of directors of Merger Sub, recommending the adoption by U.S. Parent, as sole stockholder of Merger Sub, of this Agreement, the Merger and the other transactions contemplated hereby; and immediately following execution of this Agreement, U.S. Parent, as the sole stockholder of Merger Sub, shall have adopted this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual promises herein made, and in consideration of the representations, warranties and covenants herein contained, the parties agree as follows:

ARTICLE I

THE MERGER

Section 1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company in accordance with the DGCL, whereupon the separate existence of Merger Sub shall cease and the Company shall continue as the Surviving Corporation under the Laws of the State of Delaware.

Section 1.2 Closing. Subject to the terms and conditions of this Agreement, the Closing will take place at the offices of Xxxxxxxx & Xxxxxxxx LLP, 0000 Xxxxxx Xxxxxxxxx, Xxxxx 000, XxXxxx, Xxxxxxxx 00000, at 10:00 a.m., local time, as soon as practicable but in no event later than the third Business Day after the satisfaction or waiver of the conditions (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) set forth in ARTICLE VI, or at another time, date or place as is agreed to in writing by the parties.

Section 1.3 Effective Time. Subject to the terms and conditions of this Agreement, on the Closing Date the parties hereto shall cause the Merger to be consummated by filing all necessary documentation, including a Certificate of Merger, with the Delaware Secretary, and Parent will deliver, or cause to be delivered, the Exchange Fund to the Paying Agent in the manner provided in Section 2.1. The Merger shall be effective upon filing of the Certificate of Merger with the Delaware Secretary, or on such later date as Parent and the Company agree and is specified therein (the time of such effectiveness being, the “Effective Time”).

Section 1.4 Effect of the Merger. The Merger shall have the effects set forth in the DGCL and other Applicable Law. Accordingly, without limiting the generality of the foregoing, from and after the Effective Time, the Surviving Corporation shall have all the properties, rights, privileges, powers, interests and franchises and shall be subject to all restrictions, disabilities, debts, duties and Liabilities of the Company and Merger Sub. The Surviving Corporation may, at any time after the Effective Time, take any action (including executing and delivering any document) in the name and on behalf of either the Company or Merger Sub in order to carry out and effectuate the transactions contemplated by this Agreement.

Section 1.5 Conversion of the Shares. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, U.S. Parent, Merger Sub, the Company or any of their respective securities holders:

(a) Except as provided in Section 1.5(b), each share of Common Stock issued and outstanding immediately prior to the Effective Time (the “Shares”) (excluding Appraisal Shares) shall be canceled and shall by virtue of the Merger and without any action on the part of the holder thereof be converted automatically into the right to receive $32.00 in cash, without interest (the “Merger Consideration”), upon surrender of the Certificate representing such Shares as provided in ARTICLE II. All such Shares, when so converted, shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a Certificate formerly representing such Shares shall cease to have any rights with respect thereto, except the

right to receive the Merger Consideration into which such Shares have been converted, as provided herein.

(b) Each Share that is owned by the Company (or any Subsidiary of the Company) as treasury stock or otherwise and each Share owned, directly or indirectly, by Parent immediately prior to the Effective Time shall be canceled and cease to exist 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 shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Section 1.6 Certificate of Incorporation; Bylaws.

(a) At the Effective Time, the certificate of incorporation of the Company, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation. Thereafter, subject to Section 5.10, the certificate of incorporation of the Surviving Corporation may be amended in accordance with its terms and as provided by Law.

(b) At the Effective Time, the bylaws of the Company as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation. Thereafter, subject to Section 5.10, the bylaws of the Surviving Corporation may be amended or repealed in accordance with their terms and the certificate of incorporation of the Surviving Corporation and as provided by Law.

Section 1.7 Officers and Directors of the Surviving Corporation. At the Effective Time (i) the directors of Merger Sub immediately prior to the Effective Time shall become the directors of the Surviving Corporation, and (ii) the officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, in each case until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified in accordance with and subject to Applicable Law and the certificate of incorporation and bylaws of the Surviving Corporation.

Section 1.8 Company Stock Options.

(a) Prior to the Effective Time, each Company Stock Option under or pursuant to any Company Option Plans that is outstanding, unexercised and unexpired, prior to the Effective Time shall be accelerated in full so that each such Company Stock Option is fully vested and exercisable immediately prior to the Effective Time. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, U.S. Parent, Merger Sub, the Company or the holders of Company Stock Options, each Company Stock Option which is outstanding immediately prior to the Effective Time (whether vested, unvested, exercisable or not exercisable) shall be canceled and extinguished and automatically converted into the right to receive from the Surviving Corporation an amount in cash equal to the product obtained by multiplying (x) the aggregate number of Shares that were issuable upon exercise of such Company Stock Option immediately

prior to the Effective Time and (y) the Merger Consideration less the per share exercise price of such Company Stock Option (the “Option Consideration”) (it being understood and agreed that such exercise price shall not actually be paid to the Company by the holder of a Company Stock Option). In the event the Option Consideration to any holder of a Company Stock Option is equal to or less than zero, it shall be understood and agreed that any such Company Stock Option shall be canceled and extinguished immediately upon to the Effective Time without any payment. Parent shall, or shall cause the Surviving Corporation to, pay to holders of Company Stock Options the Option Consideration, less applicable Taxes required to be deducted and withheld from payments of the Option Consideration, as soon as practicable after the Effective Time and in any case within five Business Days thereafter.

(b) Except as otherwise agreed to by the parties, the Company Option Plans shall terminate as of the Effective Time and the provisions in any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Subsidiary thereof shall be canceled as of the Effective Time.

(c) The Company shall provide notice (in a form reasonably satisfactory to Parent) to each holder of an outstanding Company Stock Option describing the treatment of such Company Stock Option in accordance with this Section 1.8.

(d) Prior to the Effective Time, the Company shall take such actions as may be necessary or desirable to give effect to the transactions contemplated by this Section 1.8, including satisfaction of the requirements of Rule 16b-3(e) under the Exchange Act and, upon the reasonable written request of U.S. Parent, using its reasonable efforts to obtain consents from holders of Company Stock Options.

Section 1.9 Restricted Stock; Deferred Compensation Plan.

(a) If any Share outstanding immediately prior to the Effective Time (determined without regard to the effect of this Section 1.9(a)) is unvested or subject to a repurchase option or forfeiture in favor of the Company (any such shares, “Company Restricted Shares”), then, effective immediately prior to the Effective Time, such Company Restricted Shares shall be fully vested and any repurchase option or forfeiture restriction shall lapse, and shall, as of the Effective Time, be cancelled and be converted into the right to receive the Merger Consideration as provided in Section 1.5, less any amounts required to be deducted and withheld under any Applicable Law as a result of such vesting.

(b) Prior to the Effective Time, all accrued account balances under the Company’s Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) shall be distributed pursuant to Section 6.1 of such plan; provided, however, that prior to any such distribution, the Company shall adopt such amendments to the Deferred Compensation Plan as it may determine to be necessary or appropriate to permit such distributions to be made without incurring the additional tax or interest penalty imposed by Section 409A(1)(B) of the Code. Following and subject to the payment of all accrued account balances under the Deferred Compensation Plan, the Company shall take all actions necessary so that such plan shall terminate at the Effective Time.

Section 1.10 Appraisal Shares. Notwithstanding anything in this Agreement to the contrary (unless otherwise provided in this Section 1.10), any Appraisal Shares shall not be converted into the right to receive the Merger Consideration as provided in Section 1.5(a), but instead such holders of Appraisal Shares shall be entitled to payment of the fair value of such shares as determined to be due to the holders of such shares in accordance with the provisions of Section 262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the rights to appraisal under Section 262, or a court of competent jurisdiction shall determine that such holder is not entitled to an appraisal of such holder’s Shares under Section 262, then the right of such holder to be paid the fair value of such holder’s Shares under Section 262 shall cease, such Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 1.5(a), without interest, and such Shares will be deemed not to be “Appraisal Shares” hereunder. The Company shall serve prompt notice to Parent of any demands for appraisal of any of the Shares, attempted withdrawals of such demands and any other instruments served pursuant to Section 262 received by the Company. The Company shall give Parent the opportunity to direct all negotiations and proceedings with respect to demand for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for appraisal, offer to settle or settle any such demands or approve any withdrawal of any such demands.

ARTICLE II

EXCHANGE OF CERTIFICATES

Section 2.1 Paying Agent. Prior to the Effective Time, Parent shall appoint the Paying Agent to act as paying agent for the payment of the Merger Consideration upon surrender of the Certificates pursuant to this ARTICLE II. On the Closing Date, Parent shall deposit, or cause to be deposited, with the Paying Agent cash in an amount sufficient to pay the aggregate Merger Consideration (such cash being hereinafter referred to as the “Exchange Fund”) payable pursuant to Section 1.5(a) in exchange for outstanding Shares. Any income from investment of the Exchange Fund, which investment shall be in accordance with the instructions of Parent or U.S. Parent, will be payable solely to Parent or U.S. Parent, as applicable. Parent shall, or shall cause U.S. Parent or the Surviving Corporation to, pay all fees and expenses of the Paying Agent.

Section 2.2 Exchange Procedures.

(a) As soon as practicable after the Effective Time, the Paying Agent shall mail to each holder of record of a Certificate or Certificates that, immediately prior to the Effective Time, represented outstanding Shares subsequently converted into the right to receive the Merger Consideration, as set forth in Section 1.5: (i) a letter of transmittal (a “Letter of Transmittal”) that (A) shall specify that delivery shall be effected and risk of loss and title to the Certificates shall pass only upon proper delivery of the Certificates to the Paying Agent (or an affidavit of loss in lieu thereof, together with any bond or indemnity agreement, as contemplated by Section 2.6) and (B) shall be in such form and have such other provisions as the Surviving Corporation may reasonably specify and the Company shall have reasonably approved and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the applicable Merger Consideration.

(b) Upon surrender of a Certificate for cancellation to the Paying Agent, together with a Letter of Transmittal, duly completed and executed, and any other documents reasonably required by the Paying Agent or the Surviving Corporation, (i) the holder of such Certificate shall be entitled to receive in exchange therefor a check representing the applicable amount of cash that such holder has the right to receive pursuant to Section 1.5 and (ii) the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on the cash payable upon surrender of the Certificates. Until surrendered as contemplated by this Section 2.2, each such Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration payable in respect of the Company Shares represented by such Certificate.

(c) In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, the appropriate amount of the Merger Consideration may be paid to a transferee if, as a condition of payment, the Certificate formerly representing such Shares is presented to the Paying Agent properly endorsed or accompanied by appropriate stock powers and otherwise in proper form for transfer and accompanied by all documents reasonably required by the Paying Agent to evidence and effect such transfer and to evidence that any applicable Taxes have been paid.

Section 2.3 No Further Ownership Transfers. All Merger Consideration paid upon the surrender for exchange of the Certificates formerly representing Shares in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Shares and, at the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this ARTICLE II, subject to Applicable Law in the case of Appraisal Shares.

Section 2.4 Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest and other income received with respect thereto) that remains undistributed to the former Company Stockholders on the date nine months after the Effective Time shall be delivered to Parent or U.S. Parent, as applicable, upon demand, and any former holder of Shares who has not theretofore received any applicable Merger Consideration to which such Company Stockholder is entitled under this ARTICLE II shall thereafter look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) for payment of claims with respect thereto and only as a general creditor thereof.

Section 2.5 No Liability. None of Parent, U.S. Parent, the Surviving Corporation or Merger Sub shall be liable to any former holder of Shares for any part of the Merger Consideration required to be delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts of Merger Consideration remaining unclaimed by former holders of any Shares as of immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Entity shall, to the extent permitted by Applicable Law, become the property of Parent or U.S. Parent, as applicable, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

Section 2.6 Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by and at the discretion of Parent, U.S. Parent, or the Surviving Corporation, the posting by such Person of a bond in such reasonable amount as Parent, U.S. Parent or the Surviving Corporation may direct, or the execution and delivery by such Person of an indemnity agreement in such form as Parent, U.S. Parent or the Surviving Corporation may direct, in each case as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate the appropriate amount of the Merger Consideration without interest.

Section 2.7 Withholding of Tax. Parent, U.S. Parent, the Surviving Corporation, any Affiliate thereof or the Paying Agent shall be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement to any holder of Shares or Company Stock Options such amounts as Parent, U.S. Parent, the Surviving Corporation, any Affiliate thereof or the Paying Agent are legally required to deduct and withhold with respect to the making of such payment under any provision of Law relating to Taxes. To the extent that amounts are so withheld by Parent, U.S. Parent, the Surviving Corporation, any Affiliate thereof or the Paying Agent, such withheld amounts shall be (a) paid over to the applicable Governmental Entity in accordance with Applicable Law or Order and (b) treated for all purposes of this Agreement as having been paid to the holder in respect of which such deduction and withholding was made.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as set forth in the Company SEC Reports filed with the SEC under the Exchange Act after January 1, 2008 and prior to the date of this Agreement (and without regard to any amendment thereto filed after the date of this Agreement) to the extent it is reasonably apparent from the disclosure or information contained in any such Company SEC Reports on its face, without further inquiry, that such information would be relevant to the applicable representation and warranty set forth in this ARTICLE III or as disclosed in the Company Disclosure Schedules (it being understood that any disclosure set forth with respect to any particular section of the Company Disclosure Schedules shall be deemed to be disclosed in reference to all other applicable sections of this ARTICLE III if the disclosure in respect of the particular section is sufficient on its face without further inquiry reasonably to inform Parent or U.S. Parent of the information required to be disclosed in respect of the other sections to avoid a breach under the representation and warranty corresponding to such other sections), the Company represents and warrants to Parent, U.S. Parent and Merger Sub as of the date of this Agreement as follows:

Section 3.1 Organization and Good Standing; Charter Documents.

conducted and (ii) is duly qualified or licensed to do business as a foreign corporation and is in good standing (with respect to jurisdictions that recognize such concept) in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except where the failure to be so qualified, licensed or in good standing, individually or in the aggregate, would not be reasonably likely to have a Company Material Adverse Effect.

(b) The copies of the Company Certificate of Incorporation and Company Bylaws that are filed as exhibits to the Company 10-K are complete and correct copies thereof as in effect on the date hereof. The Company is not in violation of any of the provisions of the Company Certificate of Incorporation or the Company Bylaws.

The execution, delivery and performance by the Company of this Agreement, and the consummation by the Company of the Merger and the other transactions contemplated by this Agreement, have been duly authorized by the Company Board of Directors and no other corporate proceedings on the part of the Company, and no other votes or approvals of any class or series of capital stock of the Company, are necessary to authorize this Agreement or to consummate the Merger or the other transactions contemplated hereby (other than the adoption of this Agreement by the Company Stockholder Vote). This Agreement has been duly executed and delivered by the Company and, assuming the due authorization, execution and delivery by Parent and Merger Sub, constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as enforcement thereof may be limited against the Company by (i) bankruptcy, insolvency, reorganization, moratorium and similar Laws affecting or relating to the enforcement of creditors’ rights or remedies in general as from time to time in effect or (ii) the exercise by courts of equity powers.

(c) Assuming the accuracy of the representations and warranties of Parent, U.S. Parent and Merger Sub in Section 4.8, as of the date of this Agreement, the Company Board of Directors has taken all action required to be taken by it to render inapplicable to this Agreement, the Merger and the other transactions contemplated hereby, the restrictions on “business combinations” (as defined in Section 203 of the DGCL) as set forth in Section 203 of the DGCL and any and all other Anti-takeover Laws.

Section 3.3 Capitalization.

The Company is the owner of all outstanding shares of capital stock (or other equity interests) of each Subsidiary of the Company and all such shares are duly authorized, validly issued, fully paid and nonassessable. All of the outstanding shares of capital stock of each Subsidiary of the Company are owned by the Company free and clear of all Encumbrances. There are no outstanding Subsidiary Stock Rights.

Section 3.5 No Conflict; Required Filings and Consents.

matters described in such exceptions shall be taken into account in determining whether there has been a Company Material Adverse Effect for purposes of this Section 5.3(d).

(e) To the extent reasonably requested by U.S. Parent, the Company shall use its best efforts to work together with U.S. Parent to obtain assurances that, in accordance with the NISPOM, the Surviving Corporation will be granted National Interest Determinations required for authorizing continued access to proscribed or other classified or unclassified controlled information following the Effective Time to the extent necessary for the Surviving Corporation to continue to perform certain of the Company’s Government Contracts; provided, however, that the Company shall not be required to use or otherwise engage direct charge personnel in the furtherance hereof. For the avoidance of doubt, Parent, U.S. Parent and Merger Sub shall continue to be obligated to consummate the Merger on the terms contemplated by this Agreement and subject only to the satisfaction or waiver of the conditions set forth in ARTICLE VI, regardless of whether (x) Parent, U.S. Parent or Merger Sub receives DSS approval to operate under U.S. Parent’s SSA under the NISPOM or such other arrangement requested by DSS or (y) indications are received from any customer with respect to any Government Contract that such customer will not grant or support a favorable National Interest Determination to or for the benefit of the Company after the Merger in response to the request for such National Interest Determination (or similar determinations under any applicable national or industrial security regulations) in accordance with the NISPOM.

(f) Each of the Company, on the one hand, and Parent, U.S. Parent and Merger Sub, on the other, shall, to the extent permitted by Applicable Law and subject to all privileges (including the attorney client privilege), promptly (and in any event within two Business Days) notify the other party in writing of:

(i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement;

(ii) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement;

(iii) any actions, suits, claims, investigations or proceedings commenced or, to its Knowledge, threatened against, relating to or involving or otherwise affecting the Company or any of its Subsidiaries or Parent and any of its Subsidiaries, as the case may be, that, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to any of the representations and warranties contained herein, or that relate to the consummation of the transactions contemplated by this Agreement;

(iv) any inaccuracy of any representation or warranty contained in this Agreement at any time during the term hereof that would reasonably be expected to cause the conditions set forth in ARTICLE VI hereto not to be satisfied; and

(v) any failure of that party to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder.

(g) In the event that the Company earnings announcement for either the third quarter or fourth quarter of 2008 would be lower than the Company’s then published earnings guidance, the Company shall provide notice of such event to Parent at least two Business Days prior to the scheduled announcement of earnings for the Company’s third quarter or fourth quarter of 2008, as applicable. Any notice provided pursuant to this Section 5.3(g) shall be deemed “Evaluation Material” under the terms of the Confidentiality Agreement.

Section 5.4 Proxy Statement.

(a) As promptly as practicable after the date hereof, the Company shall, in consultation with U.S. Parent, prepare and file with the SEC preliminary proxy materials that shall constitute the Proxy Statement. The Company agrees that none of the information supplied by the Company or any of its Subsidiaries for inclusion in the Proxy Statement will, at the date first mailed to the Company Stockholders and at the time of the Company Stockholders Meeting or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Proxy Statement shall comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations thereunder. Notwithstanding the foregoing, the Company makes no representation or warranty with respect to the information supplied by or on behalf of Parent, U.S. Parent or Merger Sub or any of their respective Representatives that is contained in the Proxy Statement. Parent and U.S. Parent agree that none of the information supplied by them for inclusion in the Proxy Statement will, at the date first mailed to the Company Stockholders and at the time of the Company Stockholders Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(b) As promptly as practicable after comments are received from the SEC thereon and after the furnishing by the Company, Parent and U.S. Parent of all information required to be contained therein, the Company shall, in consultation with U.S. Parent, prepare and the Company shall file any required amendments and the definitive Proxy Statement with the SEC. The Company shall notify U.S. Parent promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information and shall consult with U.S. Parent regarding, and supply U.S. Parent with copies of, all correspondence between the Company or any of its Representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Proxy Statement. The Company shall use its reasonable best efforts to have the Proxy Statement cleared by the SEC as promptly as reasonably practicable and shall thereafter mail to the Company Stockholders as promptly as possible the Proxy Statement and all other proxy materials for such meeting. If at any time prior to the Company Stockholders Meeting there shall occur any event that should be set forth in an amendment or supplement to the Proxy Statement so that such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Company shall promptly prepare and mail to its stockholders such an amendment or supplement.

(c) Parent shall furnish the Company with all information concerning Parent and its Affiliates required for use in the Proxy Statement, and Parent shall take such other action as the Company may reasonably request in connection with the preparation of the Proxy Statement, including any amendments or supplements thereto.

(d) The Company and Parent shall make any necessary filings with respect to the Merger under the Exchange Act and the rules and regulations thereunder.

(e) The Company shall use its reasonable best efforts to cause the Company Financial Advisor to consent to the inclusion of the Fairness Opinion in the Proxy Statement.

Section 5.5 Company Stockholders Meeting. The Company shall take all actions in accordance with Applicable Law, the Company Certificate of Incorporation, the Company Bylaws and the rules of Nasdaq to duly call, give notice of, convene and hold as promptly as practicable the Company Stockholders Meeting for the purpose of considering and voting upon the adoption of this Agreement. Subject to Section 5.6(c), to the fullest extent permitted by Applicable Law, the Company Board of Directors shall declare this Agreement advisable and recommend adoption of this Agreement and approval of the Merger by the Company Stockholders and include such recommendation in the Proxy Statement. Unless this Agreement has been duly terminated in accordance with the terms herein (including payment of any termination fees payable under ARTICLE VII), the Company shall, subject to the right of the Company Board of Directors to modify its recommendation in a manner adverse to Parent under certain circumstances as specified in Section 5.6(c), take all lawful action to solicit from the Company Stockholders proxies in favor of the proposal to adopt this Agreement and approve the Merger and shall take all other action necessary or advisable to secure the vote or consent of the Company Stockholders that are required by the rules of Nasdaq or the DGCL. In the event that subsequent to the date hereof, the Company Board of Directors determines that this Agreement is no longer advisable and makes a Change of Recommendation, the Company shall nevertheless submit this Agreement to the Company Stockholders for adoption at the Company Stockholders Meeting unless this Agreement shall have been terminated in accordance with ARTICLE VII prior to the Company Stockholders Meeting. Notwithstanding anything to the contrary contained in this Agreement, the Company, after consultation with Parent, may adjourn or postpone the Company Stockholders Meeting to the extent necessary to ensure that any legally required supplement or amendment to the Proxy Statement is provided to the Company Stockholders or, if as of the time for which the Company Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement), there are insufficient Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Company Stockholders Meeting.

Section 5.6 Acquisition Proposals.

(a) No Solicitation or Negotiation. The Company agrees that, except as expressly permitted by this Section 5.6, neither it nor any of its Subsidiaries nor any of the officers and directors of it or any of its Subsidiaries shall, and that it shall use its reasonable best efforts to instruct and cause its and its Subsidiaries’ Representatives not to, directly or indirectly:

(i) initiate, solicit or intentionally encourage any inquiries or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, any Acquisition Proposal (as defined below);

(ii) engage in, continue or otherwise participate in any discussions or negotiations regarding, or provide any non-public information or data to any Person relating to, any Acquisition Proposal; or

(iii) otherwise intentionally facilitate any effort or attempt to make an Acquisition Proposal.

Notwithstanding anything in the foregoing to the contrary, prior to the time that, but not after, the Company Stockholder Vote is obtained, if the Company has otherwise complied in all material respects with this Section 5.6 with respect to such Acquisition Proposal, the Company may (A) provide information in response to a request therefor by a Person who has made an unsolicited written Acquisition Proposal that the Company Board of Directors believes in good faith to be bona fide providing for the acquisition of more than 50% of the assets (on a consolidated basis) or total voting power of the equity securities of the Company if the Company receives from the Person so requesting such information an executed confidentiality agreement on terms not more favorable in all material respects to such other Person than those contained in the Confidentiality Agreement (except that such confidentiality agreement shall contain additional provisions that expressly permit the Company to comply with the provisions of this Section 5.6 and such confidentiality agreement need not prohibit the making of an Acquisition Proposal), and promptly discloses (and, if applicable, provides copies of) any such information to Parent to the extent not previously provided to Parent; (B) engage or participate in any discussions or negotiations with any Person who has made such an unsolicited bona fide written Acquisition Proposal of the type described in clause (A) above; or (C) after having complied with Section 5.6(c), approve, recommend, or otherwise declare advisable or propose to approve, recommend or declare advisable (publicly or otherwise) such an Acquisition Proposal, if and only to the extent that, (x) prior to taking any action described in clause (A) or (B) above, the Company Board of Directors determines in good faith (after consultation with its outside legal counsel) that failure to take such action would be inconsistent with the directors’ fiduciary duties under Applicable Law; (y) in each such case referred to in clause (A) or (B) above, the Company Board of Directors has determined in good faith based on the information then available (after consultation with the Company Financial Advisor and outside legal counsel) that such Acquisition Proposal either constitutes a Superior Proposal (as defined below) or is reasonably likely to result in a Superior Proposal; and (z) in the case referred to in clause (C) above, the Company Board of Directors determines in good faith (after consultation with the Company Financial Advisor and outside legal counsel) that such Acquisition Proposal is a Superior Proposal.

(b) Definitions. For purposes of this Agreement:

(i) “Acquisition Proposal” means (x) any proposal or offer with respect to a merger, joint venture, partnership, consolidation, dissolution, liquidation, tender offer, recapitalization, reorganization, share exchange, business combination or similar transaction involving the Company or any of its Subsidiaries and (y) any acquisition by any

Person of, or proposal or offer, which if consummated would result in any Person becoming the beneficial owner of, directly or indirectly, in one or a series of related transactions, 20% or more of the total voting power or of any class of equity securities of the Company or those of any of its Subsidiaries, or 20% or more of the consolidated total assets (including equity securities of its Subsidiaries) of the Company, in each case other than the transactions contemplated by this Agreement.

(ii) “Superior Proposal” means a bona fide Acquisition Proposal that would result in any Person becoming the beneficial owner, directly or indirectly, of more than 50% of the assets (on a consolidated basis) or more than 50% of the total voting power of the equity securities of the Company that the Company Board of Directors has determined in its good faith judgment is reasonably likely to be consummated in accordance with its terms, taking into account all legal, financial and regulatory aspects of the proposal and the Person making the proposal, and if consummated, would result in a transaction more favorable to the Company Stockholders from a financial point of view than the transaction contemplated by this Agreement (after taking into account any revisions to the terms of the transaction pursuant to Section 5.6(c) and the time likely to be required to consummate such Acquisition Proposal).

(c) No Change of Recommendation or Alternative Acquisition Agreement. The Company Board of Directors and each committee of the Company Board of Directors shall not:

(i) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify), in a manner adverse to Parent, the Company Recommendation with respect to the Merger; or

(ii) except as expressly permitted by, and after compliance with, Section 7.3(a) hereof, cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (other than a confidentiality agreement referred to in Section 5.6(a) entered into in compliance with Section 5.6(a)) (an “Alternative Acquisition Agreement”) relating to any Acquisition Proposal.

Notwithstanding anything to the contrary set forth in this Agreement, prior to the time, but not after, the Company Stockholder Vote is obtained, (x) in response to a Superior Proposal, the Company Board of Directors may withhold, withdraw, qualify or modify the Company Recommendation (or publicly propose or resolve to do so) or approve, recommend or otherwise declare advisable any Superior Proposal not solicited, entered into or agreed to in breach of this Section 5.6 and made after the date of this Agreement, if the Company Board of Directors determines in good faith, after consultation with outside legal counsel, that failure to do so would be inconsistent with its fiduciary obligations under Applicable Law (a “Change of Recommendation”); provided, however, that no such Change of Recommendation may be made until at least 72 hours following Parent’s receipt of notice from the Company advising that management of the Company currently intends to recommend to the Company Board of Directors that it take such action and the material terms of the Superior Proposal, including all required information under Section 5.6(f) (which period may run concurrently with the period contemplated in Section 7.3(a)) and (y) other than in response to a Superior Proposal, the

Company Board of Directors may withhold, withdraw, qualify or modify the Company Recommendation (or publicly propose or resolve to do so) if the Company Board of Directors determines in good faith, after consultation with outside legal counsel, that it is required by its fiduciary obligations to do so. In determining whether to make a Change of Recommendation in response to a Superior Proposal, the Company Board of Directors shall take into account any changes to the terms of this Agreement proposed by Parent and any other information provided by Parent. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 5.6(c).

(d) Certain Permitted Disclosure. Nothing contained in this Section 5.6 shall be deemed to prohibit the Company from complying with its disclosure obligations under United States federal or state Law; provided, however, that if such disclosure has the substantive effect of withdrawing or adversely modifying the Company Recommendation, such disclosure shall be deemed to be a Change of Recommendation and Parent shall have the right to terminate this Agreement as set forth in Section 7.4 (it being understood that any “stop, look or listen” communication that contains only the information set forth in Rule 14d-9(f) under the Exchange Act shall not be deemed a Change of Recommendation or be deemed to have the substantive effect of withdrawing or adversely modifying the Company Recommendation).

(e) Existing Discussions. The Company agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any Acquisition Proposal. The Company agrees that it will take the necessary steps to promptly inform the individuals or entities referred to in the first sentence of this Section 5.6(e) of the obligations undertaken in this Section 5.6; provided, however, that the filing of this Agreement with the SEC under the Exchange Act by the Company shall be deemed to promptly inform such individuals and entities for the purposes of this provision. To the extent that it has not done so prior to the date hereof, the Company also agrees that it will promptly request each Person that has heretofore executed a confidentiality agreement in connection with such Person’s consideration of acquiring the Company or any of its Subsidiaries to return or destroy all confidential information heretofore furnished to such Person by or on behalf of the Company or any of its Subsidiaries.

(f) Notice. The Company agrees that it will promptly (and, in any event, within 24 hours) notify Parent if any proposals or offers with respect to an Acquisition Proposal are received by, any such information is requested from, or any such discussions or negotiation are sought to be initiated or continued with, the Company or any of its Representatives indicating, in connection with such notice, the material terms and conditions of any proposals or offers (including, if applicable, copies of any written requests, proposals or offers, including proposed agreements) and thereafter shall keep Parent informed, on a reasonably current basis, of the status and terms of any such proposals or offers (including any amendments thereto).

Section 5.7 Public Announcements.

(a) The initial press release issued by the Company and U.S. Parent announcing the Merger and the transactions contemplated by this Agreement shall be a joint press release and in a form that is mutually acceptable to the Company and Parent. The initial press release issued by Parent announcing the Merger and the transactions contemplated by this

Agreement shall be in a form that is mutually acceptable to the Company and Parent. Thereafter, the Company, U.S. Parent and Parent shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or any of the transactions contemplated by the Transaction Documents and shall not issue any such press release or make any such public statement without the prior consent of the other party, which consent shall not be unreasonably withheld or delayed; provided, however, that a party may, without the prior consent of the other party, issue such press release or make such public statement as may be required by Law or Order or the applicable rules of Nasdaq or the London Stock Exchange or any listing agreement if it has used its reasonable best efforts to consult with the other party and to obtain such party’s consent but has been unable to do so prior to the time such press release or public statement is so required to be issued or made. Notwithstanding the foregoing, the restrictions contained in this Section 5.7 shall not apply to any Company communications regarding any Acquisition Proposal or a Change of Recommendation.

(b) Parent and the Company shall agree on the content of all general announcements made to the Company’s and its Subsidiaries’ employees regarding the execution of this Agreement and the transactions contemplated hereby (including any employee “Q&A,” group e-mails, group voicemail and any other form of communication).

Section 5.8 Litigation. Subject to Section 5.3(d), each of Parent, U.S. Parent, Merger Sub and the Company agrees to use its reasonable best efforts to defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging, or seeking damages or other relief as a result of, the Merger, this Agreement or the transactions contemplated by the Transaction Documents, including seeking to have any Order adversely affecting the ability of the parties to consummate the transactions contemplated by the Transaction Documents entered by any court or other Governmental Entity promptly vacated or reversed. Without limiting the foregoing, the Company shall provide Parent the opportunity to participate in the defense or settlement of any lawsuit or legal proceeding against the Company and its directors referred to in the first sentence of this Section 5.8 and no such settlement shall be agreed to without Parent’s prior written consent not to be unreasonably withheld, conditioned or delayed.

Section 5.9 Employee Benefit Matters.

(a) Parent shall cause the Surviving Corporation to honor and provide for payment of all accrued obligations and benefits under all Company Benefit Plans set forth, and identified as such, in the Company Disclosure Schedules (including employment or severance agreements between the Company and Persons who are or had been employees of the Company or any of its Subsidiaries at or prior to the Effective Time), all in accordance with their respective terms.

(b) For 12 months following the Effective Time, Parent will provide, or cause the Surviving Corporation to provide, each Company Employee with compensation (including bonus and incentive compensation opportunities other than equity compensation) and employee benefits (i) that, in the aggregate, are substantially similar in all material respects with the compensation and employee benefits provided to U.S. Parent’s similarly-situated employees as of the Closing Date, as the same may be modified or adjusted from time to time thereafter, or (ii) that are, in the aggregate, substantially similar in all material respects to the compensation

and employee benefits received by such Company Employees immediately prior to the Closing Date. Company Employees shall receive credit for past service with the Company for purposes of accrual of vacation time, determination of severance benefits, and for purposes of eligibility for participation and vesting under the applicable Parent Benefit Plans under which they become covered from and after the Effective Time; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits. In the event that, following the Closing but prior to the date of payment (the “Bonus Payment Date”) of annual performance bonuses for the fiscal year ending December 31, 2008 pursuant to the terms of the Company’s annual incentive plan as in effect on the date hereof (the “Company Incentive Plan”), a Company Employee’s employment with the Surviving Corporation and its Affiliates is terminated by the Surviving Corporation without “cause”, the Surviving Corporation shall, on the Bonus Payment Date, pay such Company Employee the annual performance bonus, if any, that would have been payable to such Company Employee pursuant to the Company Incentive Plan on the Bonus Payment Date had such Company Employee been employed by the Surviving Corporation on the Bonus Payment Date; provided, however, that such bonus, if any, shall be (x) based on the Company’s and the Surviving Corporation’s actual performance for the fiscal year ended December 31, 2008 and (y) pro-rata based on the number of days during the fiscal year ended December 31, 2008 that such Company Employee was actually employed by the Company or the Surviving Corporation.

(c) Parent shall use its reasonable best efforts to cause all actively-at-work or similar limitations, eligibility waiting periods and evidence of insurability requirements under any Parent Benefit Plan that is a group health plan to be waived with respect to such Company Employees and their eligible dependents, in each case, to the same extent as service with the Company or its Subsidiaries was taken into account under the comparable Company Benefit Plan, and cause credit to be provided for any co-payments, deductibles and offsets (or similar payments) made under Company Benefit Plans for the portion of the applicable plan year prior to the Effective Time for purposes of satisfying any applicable deductible, out-of-pocket or similar requirements under any Parent Benefit Plans in which they become eligible to participate after the Effective Time.

(d) Nothing contained in this Agreement, express or implied: (i) shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement, (ii) shall alter or limit the ability of Parent or any of its Subsidiaries or Affiliates to amend, modify or terminate any benefit plan, program, agreement or arrangement at any time assumed, established, sponsored or maintained by any of them, (iii) is intended to confer upon any Person any right to employment or continued employment for any period of time by reason of this Agreement, or any right to a particular term or condition of employment or (iv) is intended to confer upon any Person any other right as a third-party beneficiary of this Agreement.

Section 5.10 Directors’ and Officers’ Indemnification and Insurance.

(a) For a period of six years after the Effective Time, each of Parent, U.S. Parent and the Surviving Corporation shall, jointly and severally, indemnify and hold harmless all past and present officers and directors of the Company for acts or omissions occurring at or prior to the Effective Time, including acts or omissions occurring in connection with the transactions contemplated herein, to the fullest extent (x) permitted by the DGCL; (y) provided

under the Company Certificate of Incorporation and the Company Bylaws in effect on the date hereof (and shall also advance expenses as incurred in defense of any action, suit or proceeding to the fullest extent permitted under the DGCL; provided, that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification); or (z) provided pursuant to each indemnification agreement in existence as of the date hereof; provided, that such indemnification under (x) and (y) shall be subject to any limitation imposed from time to time under the DGCL. Parent shall cause the certificate of incorporation and the bylaws of the Surviving Corporation to contain provisions with respect to exculpation, indemnification and advancement of expenses that are at least as favorable to the indemnified parties as those contained in the Company Certificate of Incorporation and the Company Bylaws as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified for a period of not less than six years from the Effective Time in any manner that would adversely affect the rights thereunder of individuals who, immediately prior to the Effective Time, were directors, officers, employees or agents of the Company, except to the extent such a modification is required by the DGCL.

(b) For a period of six years from the Effective Time, Parent and U.S. Parent shall cause the Surviving Corporation to maintain in effect (or Parent may instead elect to maintain pursuant to Parent’s policy or policies) for the benefit of the Company’s current directors and officers an insurance and indemnification policy that provides coverage for acts or omissions occurring prior to the Effective Time that is substantially equivalent to the Company’s existing policy on terms with respect to coverage in the aggregate no less favorable than those of such policy in effect on the date hereof, or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that the Surviving Corporation shall not be required to pay an annual premium for such insurance in excess of 300% of the last annual premiums paid prior to the date hereof (which premiums the Company has disclosed to Parent), and provided, further, that, if the premium for such coverage exceeds such amount, Parent or the Surviving Corporation shall purchase a policy with the greatest coverage available for such annual premium.

(c) This Section 5.10 shall survive the consummation of the Merger, is intended to benefit the Company, the Surviving Corporation and each indemnified party, shall be binding on all successors and assigns of the Surviving Corporation, U.S. Parent and Parent, and shall be enforceable by the indemnified parties. The provisions of this Section 5.10 are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs, and his or her representatives and are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by law, charter, statute, bylaw, contract or otherwise.

(d) Parent shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by the persons referred to in this Section 5.10 in connection with their enforcement of their rights provided in this Section 5.10.

(e) In the event Parent, U.S. Parent or the Surviving Corporation 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 all or substantially all 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 Parent or the Surviving Corporation, as the case may be, shall expressly assume and succeed to the obligations set forth in this Section 5.10.

Section 5.11 Financing. Parent shall use its reasonable best efforts to (i) enter into the Draft Commitment Letter; (ii) arrange for the Financing on the terms and conditions described in the Draft Commitment Letter; (iii) enter into definitive agreements with respect to the Financing, which agreements shall be in effect as promptly as practicable after the date hereof; (iv) satisfy all conditions precedent applicable to Parent in such definitive agreements; and (v) consummate the Financing no later than the Financing Date. Parent may, in its sole discretion, obtain or seek to obtain substitute or replacement Financing from one or more alternative lenders. In the event that any portion of the Financing becomes unavailable on the terms and conditions contemplated in the Draft Commitment Letter, Parent shall obtain any such unavailable portion from alternative sources as promptly as practicable following the occurrence of such event but in no event later than the Financing Date. Parent shall promptly provide the Company with the material documentation evidencing any replacement or alternative sources of financing and shall give the Company notice within 48 hours of any material breach by any party to the Draft Commitment Letter or any termination of the Draft Commitment Letter. Parent shall keep the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to enter into the Draft Commitment Letter and to arrange for the Financing (or replacements thereof). For the avoidance of doubt, if the Draft Commitment Letter is not entered into or the Financing (or any replacement or alternative financing) has not been obtained, Parent, U.S. Parent and Merger Sub shall continue to be obligated to consummate the Merger on the terms contemplated by this Agreement and subject only to the satisfaction or waiver of the conditions set forth in ARTICLE VI.

(b) In the event that:

(i) a bona fide Acquisition Proposal shall have been made to the Company or any of its Subsidiaries or to its stockholders generally or any Person shall have publicly announced an intention (whether or not conditional) to make a bona fide Acquisition Proposal with respect to the Company or any of its Subsidiaries (and such Acquisition Proposal or publicly announced intention shall not have been publicly withdrawn without qualification at least (A) 30 Business Days prior to the date of termination (with respect to any termination pursuant to Section 7.2(a)) and (B) 10 Business Days prior to the date of the Company Stockholders Meeting (with respect to termination pursuant to Section 7.2(b))) and thereafter this Agreement is terminated by either Parent or the Company pursuant to (x) Section 7.2(a) (Outside Termination Date), provided that none of Parent, U.S. Parent or Merger Sub has materially breached this Agreement, or (y) Section 7.2(b) (No Stockholder Approval);

Section 7.7 Amendment. This Agreement may be amended by the parties in writing by action of their respective boards of directors at any time before or after the Company Stockholder Vote has been obtained and prior to the filing of the Certificate of Merger with the Delaware Secretary; provided, however, that, after the Company Stockholder Vote shall have been obtained, no such amendment, modification or supplement shall be made which by Applicable Law requires further approval by the Company Stockholders without obtaining such approval.

Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Section 7.9 Notice. The party desiring to terminate this Agreement pursuant to Sections 7.2, 7.3 or 7.4 shall give written notice of such termination to the other party in accordance with Section 8.2, specifying the provision or provisions hereof pursuant to which such termination is effected.
