2.6.          Effect on Capital Stock.  At the Effective Time, as a result of the Merger and without any action on the part of the Company, Merger Sub, the holder of any capital stock of the Company or the sole stockholder of Merger Sub:

(a)           Merger Consideration.  Each share (a “Share” and, collectively, the “Shares”) of Class A common stock, par value $0.004 per share, of the Company (the “Class A Common Stock”), and Class B common stock, par value $0.004 per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) issued and outstanding immediately prior to the Effective Time, other than (i) Shares to be cancelled pursuant to Section 2.6(d), (ii) Shares owned by Parent, Merger Sub or any other Subsidiary of Parent as of immediately prior to the Effective Time and (iii) Shares (the “Dissenting Shares”) that are, as of immediately prior to the Effective

3

Time, owned by stockholders (“Dissenting Stockholders”) who have perfected and not withdrawn a demand for, or lost their right to, appraisal pursuant to Section 262 of the DGCL with respect to such Shares (each Share referred to in clauses (i), (ii) or (iii) above being an “Excluded Share” and collectively, “Excluded Shares”), shall be converted into the right to receive $31.25 in cash (the “Per Share Merger Consideration” and the sum of all such payments, the “Total Common Stock Merger Consideration”), without interest.  Except as provided in Section 2.6(d), at the Effective Time, all of the Shares shall cease to be outstanding, shall automatically be cancelled and retired and shall cease to exist, and each certificate (a “Certificate”, it being understood that any reference herein to “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of Shares) which immediately prior to the Effective Time represented any Shares (other than Excluded Shares) shall thereafter represent only the right to receive the Per Share Merger Consideration multiplied by the number of such Shares, without interest.

(b)           Cancellation of Excluded Shares.  Each Excluded Share (other than any Shares that Parent elects to have converted into shares of capital stock of the Surviving Corporation pursuant to Section 2.6(d)) shall be cancelled and retired without payment of any consideration therefor and shall cease to exist, subject to the right of the Record Holder of any Dissenting Shares to receive the payment referred to in Section 2.7(f) with respect to such Dissenting Shares.

(c)           Merger Sub.  At the Effective Time, each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock, par value $0.01 per share, of the Surviving Corporation.

(d)           Treasury Shares; Shares Owned by Company Subsidiaries.  Any Share owned by the Company (whether held in treasury or otherwise) or any direct or indirect wholly-owned Subsidiary of the Company shall not represent the right to receive the Per Share Merger Consideration and shall be treated as an Excluded Share pursuant to Section 2.6(a) and Section 2.6(b), unless Parent elects in writing prior to the Effective Time for such Share to be converted in connection with the Merger into one share of a class of stock of the Surviving Corporation designated by Parent.

2.7.          Payment.

(a)           Paying Agent.  At the Effective Time, Parent shall deposit, or shall cause to be deposited, with a paying agent selected by Parent with the Company’s prior approval (such approval not to be unreasonably withheld) (the “Paying Agent”), for the benefit of the Record Holders of Shares, for exchange in accordance with this Article II through the Paying Agent, a cash amount in immediately available funds not less than the Total Common Stock Merger Consideration (such aggregate cash amount as deposited

4

with the Paying Agent being hereinafter referred to as the “Exchange Fund”).  If, after the Effective Time, a Dissenting Stockholder effectively withdraws its demand for, or loses its right to, appraisal pursuant to Section 262 of the DGCL with respect to any Dissenting Shares, Parent shall deposit, or shall cause to be deposited, with the Paying Agent additional funds in an amount equal to the product of (i) the number of Dissenting Shares for which the Dissenting Stockholder has withdrawn its demand for, or lost its right to, appraisal pursuant to Section 262 of the DGCL and (ii) the Per Share Merger Consideration.  If at any time the Exchange Fund shall be insufficient to make the aggregate payments contemplated by Section 2.6(a), Parent shall, or shall cause the Surviving Corporation to, promptly deposit such additional cash amounts in immediately available funds as is necessary to ensure that the Exchange Fund is maintained at a level sufficient for the Paying Agent to make such aggregate payments.

(b)           Payment Procedures.

(i)            Letter of Transmittal.  Promptly (and in any event within two Business Days) after the Effective Time, the Surviving Corporation shall cause the Paying Agent to mail to each Record Holder of Shares (other than Excluded Shares to the extent such Record Holder does not also hold Shares that are not Excluded Shares) a letter of transmittal in customary form and with such other provisions as Parent and the Company shall reasonably agree and instructions for use in surrendering the Certificates representing such Shares and determining the amount to which such Record Holder is entitled as a result of the Merger.

(ii)           Payment for Shares.  Upon delivery to the Paying Agent of such letter of transmittal by any Record Holder of Shares (other than Excluded Shares), duly completed and signed in accordance with its instructions, together with such other documents as may be reasonably required pursuant to such instructions and surrender of the Certificate (if any) that immediately prior to the Effective Time represented such Shares (or affidavit of loss in lieu thereof as provided in Section 2.7(e), or, if such Shares are held in book-entry or other uncertificated form, upon the entry through a book-entry transfer agent of the surrender of such Shares on a book-entry account statement), such Record Holder shall be entitled to receive from the Exchange Fund a cash amount in immediately available funds equal to the number of such Shares multiplied by the Per Share Merger Consideration, and, if applicable, the Certificate so surrendered shall forthwith be cancelled.  No interest will be paid or accrued on any amount payable as provided above.  Risk of loss of and title to any Certificate will pass only upon proper delivery as provided above.  In the event of a transfer of ownership of Shares that is not registered in the stock transfer books of the Company, a check for any cash to be delivered upon compliance with the procedures described above may be issued to the transferee if the applicable letter of transmittal and the Certificate representing such Shares is presented to the Paying Agent and is accompanied by

5

all documents reasonably required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid.  The Per Share Merger Consideration paid with respect to any Share in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Share.

(c)           Transfers.  From and after the Effective Time, the stock transfer books of the Company shall be closed and there shall be no transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time.  If, after the Effective Time, any Person presents to the Surviving Corporation, Parent or Paying Agent any Certificates or any transfer instructions relating to Shares cancelled in the Merger, such Person shall be given a copy of the letter of transmittal referred to in Section 2.7(b)(i) and instructed to comply with the instructions set forth therein in order to receive any cash to which such Person may be entitled with respect to such Shares pursuant to this Article II.

(d)           Termination of Exchange Fund.  Any portion of the Exchange Fund that remains unclaimed by the Record Holders of Shares on the date that is twelve (12) months after the Effective Time shall be delivered to the Surviving Corporation.  Any Record Holder of Shares (other than Excluded Shares) who has not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for payment of the Per Share Merger Consideration for such Shares upon compliance with the instructions in the form of letter of transmittal referred to in Section 2.7(b)(i), without any interest thereon.  Notwithstanding anything to the contrary herein, none of the Surviving Corporation, Parent, the Paying Agent or any other Person shall be liable to any Record Holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(e)           Lost, Stolen or Destroyed Certificates.  In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Record Holder claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Record Holder of a bond in customary amount and upon such terms as may be required by Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will issue a check in the amount equal to the number of Shares formerly represented by such lost, stolen or destroyed Certificate multiplied by the Per Share Merger Consideration, without any interest thereon.

(f)            Dissenting Shares.  No Person who, prior to the Effective Time, has perfected a demand for appraisal rights pursuant to Section 262 of the DGCL with respect to any Dissenting Shares shall be entitled to receive the Per Share Merger Consideration with respect to such Dissenting Shares unless and until such Person shall have effectively withdrawn (in accordance with Section 262(k) of the DGCL) or lost such Person’s right

6

to appraisal pursuant to the DGCL with respect to such Dissenting Shares.  Unless and until a Dissenting Stockholder shall have effectively so withdrawn or lost such Dissenting Stockholder’s right to appraisal pursuant to the DGCL with respect to such Dissenting Shares, such Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL with respect to such Dissenting Shares.  The Company shall give Parent (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law that are received by the Company relating to Company stockholders’ rights of appraisal and (ii) the opportunity to participate in all negotiations and proceedings which take place prior to the Effective Time with respect to demands for appraisal by Company stockholders 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.

(g)           Withholding Rights.  Each of Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to Record Holders of Shares or holders of Company Options or Company Restricted Stock Awards pursuant to this Agreement such Taxes as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”).  To the extent that amounts are so deducted and withheld by the Surviving Corporation, Parent or the Paying Agent, as the case may be, such deducted and withheld amounts (i) shall be remitted by Parent, the Surviving Corporation or the Paying Agent, as applicable, to the applicable Governmental Entity and (ii) shall be treated for all purposes of this Agreement as having been paid to the Record Holder of Shares in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or Paying Agent, as the case may be.

2.8.          Stock Options and Restricted Stock; Employee Stock Purchase Plan.

(a)           Treatment of Stock Options.  As of the Effective Time, each outstanding option to purchase Shares granted pursuant to any of the Company Option Plans (each, a “Company Option”) that is outstanding and unexercised immediately prior to the Effective Time (whether vested or unvested) shall automatically, by virtue of the Merger and without any action on the part of the holder of such Company Option, become fully vested and converted into the right to receive, immediately after the Effective Time (without interest thereon), a cash payment with respect thereto equal to the product of (x) the total number of Shares issuable upon exercise of such Company Option as of immediately prior to the Effective Time and (y) the excess, if any, of the Per Share Merger Consideration over the exercise price per Share under such Company Option (the “Option Cash Payment”, and the sum of all such payments, the “Total Option Cash Payments”).  As of the Effective Time, all Company Options shall automatically cease to

7

exist, and each holder of a Company Option shall cease to have any rights with respect thereto, except the right to receive the Option Cash Payment.

(b)           Treatment of Restricted Stock.  As of the Effective Time, each award of restricted stock granted pursuant to any of the Company Option Plans (each, a “Company Restricted Stock Award”) that is outstanding and unvested immediately prior to the Effective Time shall automatically, by virtue of the Merger and without any action on the part of the holder of such Company Restricted Stock Award, become fully vested and converted into the right to receive, immediately after the Effective Time, without interest thereon, a cash payment with respect thereto equal to the product of (x) the total number of Shares subject to such Company Restricted Stock Award as of immediately prior to the Effective Time and (y) the Per Share Merger Consideration (the “Restricted Stock Award Payment” and the sum of all such payments, the “Total Restricted Stock Award Payments”).  As of the Effective Time, all Company Restricted Stock Awards shall automatically cease to exist, and each holder of a Company Restricted Stock Award shall cease to have any rights with respect thereto, except the right to receive the Restricted Stock Award Payment.

(c)           Employee Stock Purchase Plan.  The Company shall take all actions necessary to ensure that (i) no offering period under the ESPP shall be commenced on or after July 1, 2011, (ii) no new participants may join the offering period in existence under the ESPP on or after the date of this Agreement and (iii) no participant may increase the amount of his or her salary deferrals with respect to such offering period. All outstanding purchase rights under the ESPP shall automatically be exercised, in accordance with the terms of the ESPP, at the end of the offering period that commences on or about April 1, 2011. The Company shall cause the ESPP to terminate with such purchase, and no further purchase rights shall be granted or exercised under the ESPP thereafter. If the Closing shall occur prior to the end of the offering period beginning on or about April 1, 2011, the Company shall cause a new exercise date to be set under the ESPP, which date shall be the Business Day immediately prior to the anticipated Closing Date.

(d)           Payments.  Promptly (and in any event within two Business Days) after the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) pay to (i) each holder of a Company Option the amount of the aggregate Option Cash Payment due and payable to such holder pursuant to Section 2.8(a), and (ii) each holder of a Company Restricted Stock Award the amount of the aggregate Restricted Stock Award Payment due and payable to such holder pursuant to Section 2.8(b).

(e)           Company Actions.  At or prior to the Effective Time, the Company, the Company Board and the Compensation Committee of the Company Board, as applicable, shall adopt such resolutions and take such actions  as are necessary to effectuate the foregoing provisions of this Section 2.8.

8

2.9.          Adjustments to Prevent Dilution.  In the event that, between the date of this Agreement and the Effective Time, the Company changes the number of Shares issued and outstanding as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer, or other similar transaction, the Per Share Merger Consideration shall be correspondingly adjusted to reflect such change and to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to the occurrence of such event, and as so adjusted shall, from and after the date of such event, be the Per Share Merger Consideration.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

Except as set forth in the corresponding sections or subsections of the disclosure schedule delivered to the Company by Parent on the date of this Agreement (the “Parent Disclosure Schedule”) (it being agreed and acknowledged that disclosure of any item in any section or subsection of the Parent Disclosure Schedule shall be deemed disclosure with respect to any other section or subsection to the extent the relevance of such item is reasonably apparent from the face of such disclosure), Parent and Merger Sub each hereby represents and warrants to the Company as follows:

4.1.          Organization, Standing and Power.  Each of Parent and Merger Sub is a corporation duly organized, validly existing and in good standing under the Laws of its jurisdiction of incorporation.  Each of Parent and Merger Sub has all requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as it is presently conducted and is qualified to do business and is in good standing as a foreign corporation or other legal entity in each jurisdiction where the ownership, leasing or operation of its assets or properties or conduct of its business requires such qualification, except where any such failure to be so qualified or in good standing would not, individually or in the aggregate, constitute a Parent Material Adverse Effect.  Parent has made available to the Company complete and correct copies of Parent’s and Merger Sub’s certificates of incorporation and by-laws (or similar governing instruments), each as amended to the date of this Agreement.

4.2.          Corporate Authority and Approval.  No vote of holders of capital stock of Parent is necessary to approve and adopt this Agreement, the Merger and the other transactions contemplated hereby.  Each of Parent and Merger Sub has all requisite corporate power and authority and has taken all corporate action necessary in order to

27

execute, deliver and perform its obligations under this Agreement and consummate the Merger and the other transactions contemplated by this Agreement, subject to adoption of this Agreement by Parent as the sole stockholder of Merger Sub, which shall occur (and evidence of which will be provided to the Company) immediately, and in any event on the date of the execution of this Agreement.  This Agreement has been duly executed and delivered by each of Parent and Merger Sub and constitutes a valid and binding agreement of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms, subject to the Bankruptcy and Equity Exception.

4.3.          No Conflict; Required Filings and Consents.

(a)           The execution, delivery and performance of this Agreement by Parent and Merger Sub, and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated hereby, do not and will not (i) conflict with or violate the certificate of incorporation or by-laws of Parent or Merger Sub, or (ii) result in any breach or violation of or constitute a default under, or give rise to any right of termination, acceleration or other alteration in the rights under, any material Contract not otherwise terminable by either party thereto upon 90 days or less notice to which Parent or Merger Sub is a party or by which any of their respective properties, assets or rights are bound or (iii) assuming compliance with the matters set forth in Section 4.3(b), violate any provision of Law applicable to Parent or Merger Sub, except, in the case of clauses (ii) and (iii) above, for any such conflict, violation, breach, default, termination, acceleration, alteration or other occurrence that would not, individually or in the aggregate, constitute a Parent Material Adverse Effect.

(b)           The execution, delivery and performance of this Agreement by Parent and Merger Sub, and the consummation of the Merger and the other transactions contemplated hereby by Parent and Merger Sub, do not and will not require any consent, approval, authorization, waiver, registration, declaration or permit of, action by, filing with or notification to, any Governmental Entity, except for (i) the applicable requirements of the Exchange Act, and the rules and regulations promulgated thereunder, (ii) the applicable requirements of the HSR Act, and the rules and regulations promulgated thereunder, (iii) the applicable requirements of the NYSE, (iv) the filing with the Secretary of State of the State of Delaware of the Certificate of Merger as required by the DGCL, (v) the applicable requirements under the NISPOM, (vi) the applicable requirements under Title 22, Section 122.4 of the ITAR, (vii) the applicable requirements of the FAR, and (viii) any such consent, approval, authorization, waiver, registration, declaration, permit, action, filing or notification the failure of which to make or obtain would not, individually or in the aggregate, constitute a Parent Material Adverse Effect.

4.4.          Litigation.  There are no Actions pending or, to the Knowledge of Parent, threatened against Parent or Merger Sub, or outstanding Orders by which Parent or

28

Merger Sub are subject or bound that would, individually or in the aggregate, constitute a Parent Material Adverse Effect.

4.5.          Financing.

(a)           Parent has delivered to the Company true, complete and correct copies of (i) an executed commitment letter, dated as of the date hereof, between Parent and the Guarantors (the “Equity Commitment Letter”), pursuant to which the Guarantors has committed, subject to the terms and conditions thereof, to invest in Parent, directly or indirectly, the cash amounts set forth therein (the “Equity Financing”), (ii) an executed rollover commitment letter (the “Rollover Letter”) from the Rollover Stockholder to contribute to Parent, directly or indirectly and subject to the terms and conditions therein, the amount of Shares set forth therein (the “Rollover Investment”) and (iii) executed commitment letters, dated as of the date hereof, among Parent, Merger Sub and the counterparties thereto (the “Debt Commitment Letters” and, together with the Equity Commitment Letter, the “Financing Letters”), pursuant to which the counterparties thereto have committed, subject to the terms and conditions thereof, to lend the amounts set forth therein (the “Debt Financing” and, together with the Equity Financing, the “Financing”).  Parent has also delivered to the Company a true, complete and correct copy of any fee letter in connection with the Debt Commitment Letters (it being understood that any such fee letter provided to the Company may be redacted to omit the numerical amounts provided therein) (any such fee letter, a “Fee Letter”).

(b)           None of the Financing Letters nor the Rollover Letter has been amended or modified prior to the date of this Agreement (provided that the existence or exercise of the “flex” provisions contained in the Fee Letters shall not constitute an amendment or modification of the Financing Letters), and, as of the date hereof, the respective commitments contained therein have not been withdrawn, terminated or rescinded in any respect.  As of the date hereof, there are no other agreements, side letters or arrangements to which Parent or Merger Sub is a party relating to the funding or investing, as applicable, of the full amount of the Financing or the Rollover Investment other than (x) as expressly set forth in the Financing Letters and the Rollover Letter and delivered to the Company prior to the entry into force of this Agreement, and (y) the Fee Letters.

(c)           Assuming the accuracy in all material respects of the representations and warranties of the Company set forth in Section 3.2 of this Agreement as of the Closing Date and performance by the Company in all material respects of its obligations under Section 5.1, the amount of funds to be provided pursuant to the Financing Letters, if funded in accordance with the terms of the Financing Letters and the contribution contemplated by the Rollover Letter will be sufficient to (i) pay the Total Common Stock Merger Consideration and the amounts payable pursuant to Section 2.8, (ii) repay the principal and interest on all indebtedness outstanding under the Credit Facility, and

29

(iii) pay all fees and expenses required to be paid at the Closing by Parent or Merger Sub in connection with the Merger and the Financing.

(d)           As of the date hereof, the Financing Letters and the Rollover Letter are in full force and effect and constitute the legal, valid and binding obligations of Parent and Merger Sub, as applicable, and, to the Knowledge of Parent, the other parties thereto (subject to the Bankruptcy and Equity Exception).  Other than as expressly set forth in the Rollover Letter, Financing Letters, and any related Fee Letter, there are no conditions precedent or other contingencies related to the funding of the full net proceeds of the Financing (including any “flex” provisions) under any agreement relating to the Financing to which Parent or any of its Affiliates is a party.  The Rollover Letter contains all of the conditions precedent to the obligations of the parties thereunder to make the contribution to Parent described therein.  As of the date hereof, no event has occurred or circumstance exists which, with or without notice, lapse of time or both, would or would reasonably be expected to constitute a default or breach on the part of Parent or Merger Sub or, to the Knowledge of Parent, any of the other parties thereto, under the Financing Letters or the Rollover Letter.  Subject to satisfaction of the conditions set forth in Sections 6.1 and 6.2, as of the date of this Agreement, Parent has no reason to believe that it will be unable to satisfy on a timely basis any condition of closing to be satisfied by it contained in the Financing Letters.  As of the date hereof, Parent and Merger Sub have fully paid, or caused to be fully paid, all commitment or other fees which are due and payable on or prior to the date hereof pursuant to the terms of the Financing Letters.

4.6.          Limited Guarantee.  Concurrently with the execution of this Agreement, the Guarantors have delivered to the Company the duly executed Limited Guarantee.  The Limited Guarantee is in full force and effect and is the valid, binding and enforceable obligation of the Guarantors, subject to the Bankruptcy and Equity Exception.  As of the date hereof, no event has occurred which, with or without notice, lapse of time or both, would constitute a default on the part of the Guarantors under the Limited Guarantee.

4.7.          Capitalization of Merger Sub.  The authorized capital stock of Merger Sub consists solely of 1,000 shares of common stock, par value $0.01 per share, all of which were duly authorized and validly issued and are fully paid and nonassessable and not subject to preemptive rights.  All of the issued and outstanding capital stock of Merger Sub is, and at the Effective Time will be, owned by Parent or a direct or indirect wholly-owned Subsidiary of Parent.  Merger Sub has not conducted any business prior to the date hereof and has no, and prior to the Effective Time will have no, assets, liabilities or obligations of any nature other than those incident to its formation and pursuant to this Agreement and the Merger and the other transactions contemplated by this Agreement.

4.8.          Solvency.  Assuming (i) the representations and warranties of the Company in this Agreement are true and correct in all material respects as of the Effective Time, (ii) that the most recent financial forecasts relating to the Company made

30

available to Parent by the Company prior to the date of this Agreement have been prepared in good faith and on assumptions that were reasonable at the time such forecasts were prepared and continue to be reasonable and (iii) satisfaction of the conditions to Parent’s obligation to consummate the Merger, after giving effect to the transactions contemplated by this Agreement (including the Financing, the Rollover Investment, the payment of the Total Common Stock Merger Consideration, the Total Option Cash Payments, the Total Restricted Stock Award Payments and all other amounts required to be paid in connection with the consummation of the Merger and the other transactions contemplated hereby, including payment of all related fees and expenses), the Surviving Corporation and its Subsidiaries taken as a whole will be Solvent at and as of the Effective Time and as of immediately after the Effective Time.

4.9.          Absence of Certain Agreements.  As of the date of this Agreement and except for the Rollover Letter and the Voting Agreement, neither Parent nor any of its Affiliates has entered into any Contract, or authorized, committed or agreed to enter into any Contract, pursuant to which (a) any stockholder of the Company would be entitled to receive consideration of a different amount or nature than the Per Share Merger Consideration in respect of its Shares or pursuant to which any stockholder of the Company agrees to vote to adopt this Agreement or the Merger, or agrees to vote against any Superior Proposal, or (b) any current employee of the Company has agreed to remain as an employee of the Company or any of its Subsidiaries following the Effective Time.

4.10.        Brokers.  No broker, finder, financial advisor, investment banker or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission or expense reimbursement in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of Parent or Merger Sub for which the Company could have any liability.

4.11.        No Other Representations or Warranties.

(a)           Except for the representations and warranties made by Parent and Merger Sub in this Article IV, none of Parent, Merger Sub or any other Person makes any express or implied representation or warranty with respect to Parent or Merger Sub or their respective businesses, assets, liabilities, condition (financial or otherwise) or prospects, and Parent and Merger Sub hereby disclaim any such other representations or warranties,   including with respect to any oral or written information furnished or made available to the Company, its Subsidiaries or any of their Affiliates or Representatives in the course of their negotiation of this Agreement or in the course of the Merger and the other transactions contemplated hereby, except for the representations and warranties made by Parent and Merger Sub in this Article IV.

(b)           Notwithstanding anything contained in this Agreement to the contrary, each of Parent and Merger Sub acknowledges and agrees that neither the Company nor

31

any other Person has made or is making any representations or warranties relating to the Company whatsoever, express or implied, beyond those expressly given by the Company in Article III, including any implied representation or warranty as to the accuracy or completeness of any information regarding the Company furnished or made available to Parent, Merger Sub or any of their Representatives.  Without limiting the generality of the foregoing, each of Parent and Merger Sub acknowledges that no representations or warranties are made with respect to any projections, forecasts, estimates, budgets or prospect information that may have been made available to Parent, Merger Sub or any of their Representatives.

(c)                                  Notwithstanding anything to the contrary contained in Section 5.2(b), at any time following the No Shop Period Start Date and prior to the time the Company Stockholder Approval is obtained, if the Company receives a bona fide, written Acquisition Proposal from any Person, (i) the Company and its Representatives may provide information (including non-public information and data) regarding, and afford access to, the business, properties, assets, books, records and personnel of, the Company and its Subsidiaries in response to a request therefor by such Person if the Company receives from such Person (or has received from such Person) an executed Acceptable Confidentiality Agreement and (ii) the Company and its Representatives may engage in, enter into, continue or otherwise participate in any discussions or negotiations with such Person with respect to such Acquisition Proposal, if and only to the extent that prior to taking any action described in clause (i) or (ii) above, (x) the Company Board determines in good faith (after consultation with outside legal counsel) that (A) failure to take such action would reasonably be expected to be inconsistent with the directors’ fiduciary duties to stockholders under applicable Law and (B) based on the information then

37

available and after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal either constitutes a Superior Proposal or would reasonably be expected to result in a Superior Proposal and (y) the Company shall give written notice to Parent of any such determination by the Company Board.  The Company shall promptly provide Parent with copies of any information or materials regarding the Company and its Subsidiaries provided or made available to such other Person which were not previously made available to Parent.

(d)                                 Except as set forth in this Section 5.2(d), the Company Board shall not (i) change, 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 fail to include the Company Recommendation in the Proxy Statement (any of the foregoing, a “Change of Recommendation”), (ii) authorize, adopt, approve, recommend or declare advisable, or propose to authorize, adopt, approve, recommend or declare advisable (publicly or otherwise), an Acquisition Proposal, or (iii) cause or permit the Company to enter into any Alternative Acquisition Agreement.  Notwithstanding anything to the contrary set forth in this Agreement, prior to the time the Company Stockholder Approval is obtained, the Company Board may (x) if an event, fact, development or occurrence that affects the business, assets or operations of the Company that is unknown to the Company Board as of the date of this Agreement becomes known to the Company Board (an “Intervening Event”), effect a Change of Recommendation or (y) if the Company receives a written Acquisition Proposal that the Company Board determines in good faith (after consultation with its financial advisor and outside legal counsel) constitutes a Superior Proposal, approve, recommend or declare advisable, and authorize the Company to enter into an Alternative Acquisition Agreement with respect to, such Superior Proposal and terminate this Agreement pursuant to Section 7.3(a) if, in the case of either of clause (x) or (y):

(i)                                     the Company Board determines in good faith, after consultation with outside legal counsel, that failure to do so would reasonably be expected to be inconsistent with its fiduciary duties to stockholders under applicable Law and the Company shall have complied with all of its obligations under this Section 5.2;

(ii)                                  the Company shall have provided prior written notice to Parent, at least four Business Days in advance, that it intends to effect a Change of Recommendation or terminate this Agreement pursuant to Section 7.3(a), which notice shall specify the basis for the Change of Recommendation or termination and, in the case of a Superior Proposal, the identity of the party making such Superior Proposal and the material terms thereof and include copies of all relevant documents relating to such Superior Proposal;

38

(iii)                               after providing such notice and prior to effecting such Change of Recommendation or terminating this Agreement pursuant to Section 7.3(a), the Company shall have, and shall have caused its Representatives to, negotiate with Parent and Merger Sub in good faith during such four Business Day period (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement as would permit the Company Board not to effect a Change of Recommendation or terminate this Agreement pursuant to Section 7.3(a); and

(iv)                              the Company Board shall have considered in good faith any changes to this Agreement offered in writing by Parent no later than 5:00 p.m., New York City time, on the fourth Business Day of such four Business Day period and shall have determined (x) in the event the Company Board’s determination pursuant to clause (d)(i) above is in response to a Superior Proposal, that such Superior Proposal would continue to constitute a Superior Proposal if such changes offered in writing by Parent were to be given effect; provided that, in the event of any material revisions to the Acquisition Proposal that the Company Board has determined to be a Superior Proposal, the Company shall be required to deliver a new written notice to Parent in respect of such modified Acquisition Proposal and to again comply with the requirements of this Section 5.2(d) with respect to such new written notice, except that the applicable time periods for purposes of this Section 5.2(d) with respect to such new written notice shall be reduced to two Business Days from the four Business Day period otherwise contemplated or (y) in the event the Company Board’s determination pursuant to clause (d)(i) above is in response to an Intervening Event, that such changes would not affect the Company’s Board determination of the need for a Change of Recommendation in response to such Intervening Event.

(e)                                  Nothing contained in this Section 5.2 shall be deemed to prohibit the Company or the Company Board or any committee thereof from (i) complying with its disclosure obligations under U.S. federal or state Law with regard to an Acquisition Proposal, including taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) under the Exchange Act (or any similar communication to stockholders), or (ii) making any “stop-look-and-listen” communication to the stockholders of the Company pursuant to Rule 14d-9(f) under the Exchange Act (or any similar communications to the stockholders of the Company); provided that any such disclosure (other than a “stop-look-and-listen” communication or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed for all purposes of this Agreement to be a Change of Recommendation unless the Company Board expressly publicly reaffirms the Company Recommendation within four Business Days following any request by Parent (it being agreed that Parent may make only one such request with respect to any single such disclosure).

39

(f)                                    From and after the No Shop Period Start Date, the Company shall promptly (and, in any event, within 24 hours) notify Parent (orally and in writing) if any Acquisition Proposal is received by or any non-public information is requested from the Company or any of its Representatives, indicating the identity of the Person or group of Persons making such offer or proposal and 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 reasonably informed, on a reasonably current basis, of the status and terms of any such proposals or offers (including any amendments thereto) and the status of any discussions or negotiations, including any change in the Company’s intentions as previously notified.

(g)                                 The Company shall not, and shall cause its Subsidiaries not to, enter into any confidentiality agreement with any Person relating to a possible Acquisition Proposal subsequent to the date of this Agreement except for an Acceptable Confidentiality Agreement as permitted or required pursuant to this Section 5.2, and neither the Company nor any of its Subsidiaries shall enter into any agreement that prohibits the Company from providing to Parent any information provided or made available to any other Person pursuant to an Acceptable Confidentiality Agreement.

(h)                                 The Company acknowledges and agrees that any violation of the restrictions set forth in this Section 5.2 by any Representatives of the Company shall be deemed to be a breach of this Section 5.2 by the Company.

5.3.                              Proxy Statement; Schedule 13E-3

(a)                                  As promptly as practicable and in any event within fifteen Business Days after the date hereof, the Company shall prepare and file with the SEC a preliminary proxy statement relating to the Stockholders Meeting (together with any amendments thereof or supplements thereto, the “Proxy Statement”) and the Company and Parent shall jointly prepare and file the Schedule 13E-3 and the Company and Parent shall reasonably cooperate with each other in connection with the preparation of the foregoing.  The Company agrees that, assuming Parent’s compliance with the last sentence of this Section 5.3(a), the Proxy Statement and the Schedule 13E-3 (i) will comply in all material respects with the applicable provisions of the Exchange Act and the rules and regulations thereunder and (ii) will not, with respect to the Proxy Statement, on the date it is first mailed to stockholders of the Company and at the time of the Stockholders Meeting and, with respect to the Schedule 13E-3, the date it is first filed with the SEC, 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.  Notwithstanding the foregoing, the Company assumes no responsibility with respect to information supplied in writing by or on behalf of Parent or Merger Sub for inclusion or incorporation by reference in the Proxy Statement or the Schedule 13E-3.  Without limiting the generality of the foregoing,

40

each of Parent and Merger Sub shall cooperate with the Company in connection with the preparation and filing of the Proxy Statement and the Schedule 13E-3, including promptly furnishing to the Company in writing upon reasonable request any information relating to it as may be required to be set forth in the Proxy Statement or Schedule 13E-3 under applicable Law.  Parent shall ensure that such information supplied by it in writing for inclusion (or incorporation by reference) in the Proxy Statement and the Schedule 13E-3 will not, on the date it is first mailed to stockholders of the Company and at the time of the Company Stockholders Meeting or filed with the SEC (as applicable), 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 the light of the circumstances under which they were made, not misleading.

(b)                                 The Company shall promptly notify Parent of the receipt of all comments of the SEC with respect to the Proxy Statement or the Schedule 13E-3 and of any request by the SEC for any amendment or supplement thereto or for additional information and shall promptly provide to Parent copies of all correspondence between the Company or any of its Representatives and the SEC with respect to the Proxy Statement or the Schedule 13E-3.  The Company and Parent shall each use its reasonable best efforts to promptly provide responses to the SEC with respect to all comments received on the Proxy Statement or the Schedule 13E-3 from the SEC and to make any amendments or filings as may be necessary in connection therewith.  The Company shall cause the definitive Proxy Statement to be mailed promptly after the date the SEC staff advises that it has no further comments thereon or that the Company may commence mailing the Proxy Statement; provided that the Company shall not be required to mail the Proxy Statement prior to the No Shop Period Start Date.

(c)                                  Subject to applicable Law, the Company shall cooperate and provide Parent with a reasonable opportunity to review and comment on the draft of the Proxy Statement (including each amendment or supplement thereto), and the parties hereto shall cooperate and provide each other with a reasonable opportunity to review and comment on the draft Schedule 13E-3 (including each amendment or supplement thereto) and all responses to requests for additional information by and replies to comments of the SEC, prior to filing such with or sending such to the SEC, and the parties hereto will provide each other with copies of all such filings made and correspondence with the SEC.

5.4.                              Stockholders Meeting.

(a)                                  The Company will take, in accordance with applicable Law and its certificate of incorporation and by-laws, all reasonable action necessary to convene a meeting of holders of Shares (the “Stockholders Meeting”) within 35 days after the date of mailing of the Proxy Statement to consider and vote upon the adoption of this Agreement; provided that the Company may postpone or adjourn to a later date the Stockholders Meeting (i) with the consent of Parent, (ii) for the absence of a quorum, or

41

(iii) to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure that the Company has determined in good faith is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the Company’s stockholders prior to the Stockholders Meeting.

(b)                                 The Company shall postpone or adjourn to a later date the Stockholders Meeting on one occasion at the request of Parent.  Subject to the right of the Company Board to make a Change of Recommendation in accordance with Section 5.2(d), the Company Board shall recommend adoption of this Agreement by its stockholders at the Stockholders Meeting and shall take all reasonable lawful action to solicit such adoption of this Agreement.

(c)                                  The Company shall establish a record date for purposes of determining stockholders entitled to notice of and vote at the Stockholders Meeting (the “Record Date”) that is approximately 35 days prior to the date of the Stockholders Meeting.  Once the Company has established the Record Date, the Company shall not change such Record Date or establish a different record date for the Stockholders Meeting without the prior written consent of Parent, unless required to do so by applicable Law or the Company’s bylaws.  In the event that the date of the Stockholders Meeting as originally called is for any reason adjourned or postponed or otherwise delayed, the Company agrees that unless Parent shall have otherwise approved in writing, it shall implement such adjournment or postponement or other delay in such a way that the Company does not establish a new Record Date for the Stockholders Meeting, as so adjourned, postponed or delayed, except as required by applicable Law or the Company’s bylaws.  Without the prior written consent of Parent, the adoption of this Agreement shall be the only matter (other than procedural matters) that the Company shall propose to be acted on by the stockholders of the Company at the Stockholders Meeting.

5.5.                              Reasonable Best Efforts; Filings; Other Actions.

(a)                                  Upon the terms and subject to the conditions of this Agreement, and without limiting any express obligations of the parties hereunder, each party hereto shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary, proper or advisable on its part under this Agreement and applicable Laws to consummate and make effective the Merger and the other transactions contemplated hereby.  Notwithstanding anything to the contrary contained in this Agreement, all obligations of the Company, Parent and Merger Sub to obtain the Financing or any other financing for the Merger and the other transactions contemplated hereby shall be governed exclusively by Sections 5.12 and 5.13, and not this Section 5.5.  Without limiting the foregoing, promptly following the execution of this Agreement, each party hereto shall use its reasonable best efforts to make all registrations, filings, notifications and submissions

42

(i)                                     that are required to be submitted to the Defense Security Service of the United States Department of Defense or any other United States Cognizant Security Agency in respect of the transactions contemplated by this Agreement in accordance with Paragraph 2-302(b) of the NISPOM; and

(ii)                                  that are required to be submitted to the United Stated Department of State Directorate of Defense Trade Controls in respect of the transactions contemplated by this Agreement in accordance with the ITAR.

(c)                                  The Company, Parent and Merger Sub shall each use its reasonable best efforts to resolve such objections, if any, as may be asserted with respect to the Merger and the other transactions contemplated hereby under any Regulatory Law.  If any Action, including any Action by a private party, is instituted (or threatened to be instituted) challenging the Merger and the other transactions contemplated hereby as violative of any Regulatory Law, each of the Company, Parent and Merger Sub shall cooperate in all respects and use its respective reasonable best efforts to contest and resist any such Action and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other Order (whether temporary, preliminary or permanent) that is in effect and that restricts, prevents or prohibits consummation of the Merger and the other transactions contemplated hereby, including by pursuing all reasonable avenues of administrative and judicial appeal.

(d)                                 Each of the Company, Parent and Merger Sub shall (i) subject to any restrictions under any Regulatory Law, to the extent practicable, promptly notify each other of any communication to that party from any Governmental Entity (including the Federal Trade Commission and the Antitrust Division of the Department of Justice) with respect to this Agreement and the Merger and the other transactions contemplated hereby and permit the other party to review in advance any proposed written communication to any Governmental Entity in respect thereof, (ii) unless required by applicable Law, not

43

agree to participate in any meeting with any Governmental Entity in respect of any filings, investigation or other inquiry with respect to this Agreement and the Merger and the other transactions contemplated hereby unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate thereat, in each case to the extent practicable, (iii) subject to any restrictions under any Regulatory Law, furnish the other party with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between it and its Affiliates and their respective Representatives on the one hand, and any Governmental Entity or members of its staff on the other hand, with respect to this Agreement and the Merger and the other transactions contemplated hereby (excluding documents and communications which are subject to preexisting confidentiality agreements or to the attorney-client privilege or work product doctrine), and (iv) furnish the other party with such necessary information and reasonable assistance as such other party and its Affiliates may reasonably request in connection with their preparation of necessary filings, registrations or submissions of information to any Governmental Entity in connection with this Agreement and the Merger and the other transactions contemplated hereby, including without limitation any filings necessary or appropriate under the provisions of any Regulatory Law.

(e)                                  Notwithstanding anything in this Agreement to the contrary, Parent and Merger Sub shall take any and all action necessary, including but not limited to (i) selling or otherwise disposing of, or holding separate and agreeing to sell or otherwise dispose of, assets, categories of assets or businesses of the Company or its Subsidiaries; (ii) terminating existing relationships, contractual rights or obligations of the Company or its Subsidiaries; (iii) terminating any venture or other arrangement; (iv) creating any relationship, contractual rights or obligations of the Company or its Subsidiaries or (v) effectuating any other change or restructuring of the Company or its Subsidiaries (and, in each case, to enter into agreements or stipulate to the entry of an order or decree or file appropriate applications with any Governmental Entity in connection with any of the foregoing, and by consenting to such action by the Company, provided, in each case, that any such action shall be conditioned upon consummation of the Merger) (each a “Divestiture Action”) to ensure that no Governmental Entity enters any order, decision, judgment, decree, ruling, injunction (preliminary or permanent), or establishes any law, rule, regulation or other action preliminarily or permanently restraining, enjoining or prohibiting the consummation of the Merger, or to ensure that no Governmental Entity with the authority to clear, authorize or otherwise approve the consummation of the Merger, fails to do so by the Termination Date.  In the event that any action is threatened or instituted challenging the Merger as violative of any pre-merger notification requirement or other Regulatory Law, Parent shall take all action necessary, including but not limited to any Divestiture Action, to avoid or resolve such action.  Notwithstanding anything to the contrary in this Section 5.5, in no event shall this Section 5.5 require Parent or Merger Sub to take any action, including any Divestiture Action, that would reasonably be expected to result in a material adverse effect on the financial condition,

44

business, properties, assets or results of operations of the Company and its Subsidiaries, taken as a whole.

(f)                                    If any Divestiture Action agreed to by Parent requires action by or with respect to the Company or its Subsidiaries or its or their respective businesses or assets, and such action would constitute a breach of this Agreement, Parent hereby agrees to consent to the taking of such action by the Company or any of its Subsidiaries, and any such action may, at the discretion of the Company, be conditioned upon the consummation of the Merger.

(g)                                 Without limiting the generality of the foregoing, if applicable, the Company shall cooperate with and provide reasonable assistance to Parent in Parent’s efforts to obtain from DSS approval to operate the business of the Company from and after the Closing pursuant to a FOCI mitigation arrangement in accordance with the NISPOM.

(h)                                 The Company shall cooperate and provide such reasonable assistance to Parent and Merger Sub, and Parent and Merger Sub shall cooperate and provide such reasonable assistance to the Company, as may be reasonably required in the event that any Governmental Entity requires a novation of any Government Contract.  To the extent any Government Contract or Government Bid requires notification to a Governmental Entity with respect to the execution of this Agreement or the consummation of the Merger and the other transactions contemplated hereby, the Company shall use its reasonable best efforts to make all such notifications as promptly as practicable following the execution of this Agreement.

5.6.                              Access and Reports.

(a)                                  Subject to applicable Law and, with respect to any classified or controlled unclassified materials, to the compliance by Parent, Merger Sub and each of their respective Representatives’ with any security clearance requirements and procedures or export controls requirements (to the extent determined necessary or advisable by the Company in order to comply with applicable Law), from and after the date of this Agreement to the Effective Time, upon reasonable notice, the Company shall, and shall cause each of its Subsidiaries to, (i) afford to Parent, Merger Sub and each of their respective Representatives, reasonable access, during normal business hours, to its personnel, offices and other facilities, properties, books, contracts and records and (ii) furnish or cause to be furnished such information concerning the business, properties, assets, liabilities and personnel of the Company and its Subsidiaries as Parent, Merger Sub or their respective Representatives may reasonably request; provided that the foregoing shall not require the Company to provide access or information if such action would, in the reasonable judgment of the Company, (i) violate any Contract or any obligation or agreement with respect to confidentiality or nondisclosure owing to any

45

third-party (including any Governmental Entity) so long as the Company shall have used reasonable best efforts to obtain the consent of such third party to such inspection or disclosure, (ii) constitute a waiver of the attorney-client or other privilege held by the Company or any of its Subsidiaries if the Company shall have used reasonable best efforts to disclose such information in a way that would not waive such privilege or (iii) to the extent such information relates to individual performance or personnel evaluation records, medical histories or other personnel information, subject the Company or any of its Subsidiaries to potential material liability (provided that the parties shall cooperate in seeking a manner of disclosure of such information that would not reasonably be expected to result in potential material liability to the Company or any of its Subsidiaries).  Any access to the properties of the Company or any of its Subsidiaries granted pursuant to this Section 5.6(a) shall be subject to the Company’s reasonable security measures and insurance requirements, and shall not include the right to perform any invasive testing.

(b)                                 The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, (i) of any notice or other communication received by such party from any Governmental Entity in connection with the transactions contemplated by this Agreement or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement, if the subject matter of such communication or the failure of such party to obtain such consent could be material to the Company, the Surviving Corporation or Parent, (ii) of any Action commenced or, to such party’s knowledge, threatened against, relating to or otherwise affecting such party or any of its Subsidiaries in connection with, arising from or relating to this Agreement or the Merger and the other transactions contemplated hereby (“Transaction Litigation”) and (iii) if such party becomes aware of any facts or circumstances that such party believes do, or with the passage of time are reasonably likely to, constitute a breach of this Agreement by such party or the occurrence or non-occurrence of any event that, individually or in the aggregate, would reasonably be expected to cause any condition to the obligations of the other party hereto to effect the Merger or any of the other transactions contemplated by this Agreement not to be satisfied; provided that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of any party to effect the Merger under this Agreement.

5.7.                              Publicity.

(a)                                  The initial press release regarding the Merger shall be a joint press release by the Company and Parent and thereafter (unless the Company Board shall have effected a Change of Recommendation or in connection with Section 5.2(e), in which case the obligations set forth in this Section 5.7 shall not be applicable) the Company and Parent each shall consult with the other prior to issuing, and to the extent reasonably practicable under the circumstances give each other the opportunity to review and

46

comment upon, any press releases or otherwise making any public announcements with respect to the Merger or any of the other transactions contemplated by this Agreement and prior to making any filings with any third party and/or any Governmental Entity (including any national securities exchange or interdealer quotation service) with respect thereto, except that the limitations of this Section 5.7 shall not be applicable where such public announcements or filings are (a) required by Law or by applicable obligations pursuant to any listing agreement with or rules of any national securities exchange or interdealer quotation service, or (b) made at the request of any Governmental Entity.

(b)                                 Upon Parent’s request, (i) the Company and Parent shall cooperate to prepare, promptly following such request, a joint written presentation reasonably acceptable to both parties to Institutional Shareholder Services Inc. (and such other proxy voting advisory services reasonably requested by Parent) recommending this Agreement and the transactions contemplated hereby, including the Merger, and (ii) the Company shall request a meeting with each such proxy voting advisory service for purposes of obtaining its recommendation of the adoption of this Agreement by the Company’s stockholders.

5.8.                              Employee Benefits.

(a)                                  For a period of not less than one year following the Closing Date, the Surviving Corporation shall provide each individual who is a current employee of the Company or one of its Subsidiaries (including any current employee who is not actively at work on account of illness, disability or leave of absence) on the Closing Date (the “Affected Employees”), while employed by the Surviving Corporation or any of its Subsidiaries, with compensation and benefits that are no less favorable in the aggregate to the compensation and benefits provided to such Affected Employee as of the date of this Agreement (other than (i) equity compensation incentives, (ii) any compensation or benefits triggered in whole or in part by the consummation of the Merger and the other transactions contemplated hereby and (iii) cash incentives in respect of the Company’s fiscal year beginning on July 1, 2012).  Nothing contained in this Section 5.8 shall be deemed to grant any Affected Employee any right to continued employment after the Closing Date.

(b)                                 Parent will cause any employee benefit plans of Parent and its Subsidiaries (other than the Surviving Corporation and its Subsidiaries) in which the Affected Employees are entitled to participate after the Closing Date to take into account for purposes of eligibility, vesting and, under any plan providing severance benefits or paid time off, level of benefits, service by such employees as if such service were with Parent or its Subsidiaries, to the same extent such service was credited under a comparable Plan (except to the extent it would result in a duplication of benefits).

47

(c)           With respect to any employee benefit plans maintained by Parent and its Subsidiaries for the benefit of the Affected Employees following the Closing Date (“New Plans”), Parent will cause the Surviving Corporation and its Subsidiaries to (i) cause there to be waived any eligibility requirements or pre-existing condition limitations or waiting period requirements to the same extent waived under comparable Plans prior to the time coverage under the New Plans commences and (ii) give effect, in determining any deductible, co-insurance and maximum out-of-pocket limitations, amounts paid by such employees during the year in which coverage under the New Plans commences under comparable Plans.

(d)           From and after the Effective Time, Parent shall cause the Surviving Corporation and any successor thereto to assume, honor, fulfill and discharge the Company’s and its Subsidiaries’ obligations under the agreements or arrangements set forth on Schedule 5.8(d) of the Company Disclosure Schedule in accordance with the terms of such agreements or arrangements.

(e)           Nothing contained in this Section 5.8, whether express or implied, (i) shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement or (ii) is intended to confer upon any Person (including any current or former employee, director or consultant of the Company or any of its Subsidiaries) any rights as a third-party beneficiary of this Agreement.

5.9.          Expenses.  Except as otherwise provided in this Agreement, all costs and expenses incurred in connection with this Agreement and the Merger and the other transactions contemplated by this Agreement shall be paid by the party incurring such expense, without regard to whether the Merger and the other transactions contemplated by this Agreement are consummated.  The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, in connection with the transactions contemplated in Article II.

5.10.        Indemnification; Directors’ and Officers’ Insurance.

49

so that the successors and assigns of the Surviving Corporation shall assume all of the obligations set forth in this Section 5.10.

(d)           The provisions of this Section 5.10 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties.

5.12.        Financing.

(a)           Subject to the terms and conditions of this Agreement, each of Parent and Merger Sub shall not permit any amendment or modification to be made to, or any waiver of any provision or remedy under, the Financing Letters or the Rollover Letter, if such amendment, modification or waiver would, or would reasonably be expected to, (i) (A) with respect to the Financing Letters, reduce the aggregate amount of the Financing (unless the Rollover Investment is increased by a corresponding amount) or (B) with respect to the Rollover Letter, reduce the amount of Shares to be contributed (unless the Financing is increased by a corresponding amount), or (ii) impose new or additional conditions or other terms or otherwise expand, amend or modify any of the conditions to the receipt of the Financing or the contribution contemplated by the Rollover Letter or other terms in a manner that would reasonably be expected to (x)  materially delay or prevent the Closing Date or (y) make the timely funding of the Financing or the contribution contemplated by the Rollover Letter, or satisfaction of the conditions to obtaining the Financing or the contribution contemplated by the Rollover Letter, materially less likely to occur.  Any reference in this Agreement to (i) “Financing” shall

50

include the financing contemplated by the Financing Letters as amended or modified in compliance with this Section 5.12, (ii) the “Rollover Investment” shall include the financing contemplated by the Rollover Letter as amended or modified in compliance with this Section 5.12  and (iii) “Financing Letters”, “Rollover Letter” or “Debt Commitment Letter” shall include such documents as amended or modified in compliance with this Section 5.12(a).

51

(B) material dispute or disagreement between or among any parties to any Financing Letters, Rollover Letter or any definitive document related to the Financing and (z) if for any reason Parent or Merger Sub believes in good faith that it will not be able to obtain all or any portion of the Financing or the Rollover Investment on the terms, in the manner or from the sources contemplated by the Financing Letters, the Rollover Letter or the definitive documents related to the Financing.

(c)           Subject to the terms and conditions of this Agreement, if any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letters, Parent shall use its reasonable best efforts to arrange to obtain alternative financing from alternative sources on terms and conditions not less favorable in the aggregate to Parent and Merger Sub than those contained in the Debt Commitment Letters and the related Fee Letter and in an amount at least equal to the Debt Financing or such unavailable portion thereof, as the case may be (the “Alternate Debt Financing”), and to obtain a new financing commitment letter with respect to such Alternate Debt Financing (the “New Debt Commitment Letters”), which shall replace the existing Debt Commitment Letters in whole or in part, a copy of which shall be promptly provided to the Company.  In the event any New Debt Commitment Letters are obtained, (i) any reference in this Agreement to the “Financing” or the “Debt Financing” shall mean the debt financing contemplated by the Debt Commitment Letters as modified pursuant to clause (ii) below and (ii) any reference in this Agreement to the “Financing Letters” or the “Debt Commitment Letters” shall be deemed to include the Debt Commitment Letters to the extent not superseded by a New Debt Commitment Letter at the time in question and any New Debt Commitment Letters to the extent then in effect.

(d)           Notwithstanding anything to the contrary contained in this Agreement, nothing contained in this Section 5.12 shall require, and in no event shall the reasonable best efforts of Parent or Merger Sub be deemed or construed to require, either Parent or Merger Sub to (i) bring any enforcement action against any source of the Equity Financing to enforce its respective rights under the Equity Commitment Letter or against the Rollover Stockholder to enforce its rights under the Rollover Letter except that Parent shall seek to enforce, including by bringing suit for specific performance, the Equity Commitment Letter and the Rollover Letter if and only if the Company seeks and is granted a decree of specific performance of the obligation to consummate the Merger after all conditions to the granting thereof set forth in Section 8.7(b) have been satisfied, (ii) seek the Equity Financing or the Rollover Investment from any source other than those counterparty to, or in any amount in excess of that contemplated by, the Equity Commitment Letter or the Rollover Letter, as applicable, or (iii) pay any fees in excess of those contemplated by the Financing Letters (whether to secure waiver of any conditions contained therein or otherwise).

(e)           Parent and Merger Sub each acknowledge and agree that the obtaining of the Financing or the Rollover Investment is not a condition to Closing.  For the avoidance

52

of doubt, if the Financing or the Rollover Investment has not been obtained, Parent and Merger Sub shall each continue to be obligated, subject to the satisfaction or waiver of the conditions set forth in Article VI, to consummate the Merger and the other transactions contemplated by this Agreement.  Notwithstanding the foregoing, the Company acknowledges and agrees that in the event the Merger and other transactions contemplated by this Agreement are not consummated, the Company’s sole and exclusive remedies are those set forth in Sections 7.5 and 8.7.

8.7.                              Specific Performance.

(a)                                  The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder in order to consummate this Agreement) in accordance with its specified terms or otherwise breach such provisions.  The parties acknowledge and agree that, prior to the valid termination of this Agreement pursuant to Article VII, the parties shall be entitled, in addition to any other remedy to which they are entitled at law or in equity, to an injunction, specific performance and other equitable

68

relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, except as provided in Section 8.7(b).

(b)                                 Notwithstanding Section 8.7(a), it is expressly agreed that the Company shall be entitled to seek specific performance of Parent’s obligation pursuant to the terms of this Agreement to cause the Rollover Investment to be made and the Equity Financing to be funded to fund the Merger and to consummate the Merger in the event that (i) all of the conditions set forth in Sections 6.1 and 6.2 have been satisfied (other than those conditions that by their terms are to be satisfied by actions taken at the Closing, each of which is capable of being satisfied at the Closing), (ii) the Debt Financing has been funded or will be funded at the Closing if the Equity Financing is funded at the Closing and the Rollover Investment is made at Closing, (iii) Parent and Merger Sub fail to complete the Closing in accordance with Section 1.2 and (iv) the Company has irrevocably confirmed in a written notice to Parent that if specific performance is granted and the Equity Financing and Debt Financing are funded and the Rollover Investment is made, then the Closing will occur.  For the avoidance of doubt, in no event shall the Company be entitled to enforce or seek to enforce specifically Parent’s obligation to cause the Rollover Investment to be made and the Equity Financing to be funded or to complete the Merger if the Debt Financing has not been funded (or will not be funded at the Closing if the Equity Financing is funded at the Closing and the Rollover Investment is made at the Closing).

(c)                                  Each party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that (i) there is adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or equity.  Any party seeking an injunction or injunctions to prevent breaches of this Agreement when expressly available pursuant to the terms of this Agreement and to enforce specifically the terms and provisions of this Agreement when expressly available pursuant to the terms of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

8.8.                              Entire Agreement.  This Agreement (including any exhibits hereto), the Company Disclosure Schedule, the Limited Guarantee and the Confidentiality Agreement, dated as of May 18, 2010, between Providence Equity Partners LLC and the Company (as the same may be amended, modified, supplemented or waived from time to time in accordance with its terms, the “Confidentiality Agreement”) constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties both written and oral, among the parties, with respect to the subject matter hereof.

8.9.                              No Third Party Beneficiaries.  Except (i) for the rights under Article II on and after the Effective Time of the holders of Shares, Company Options and Company

69

Restricted Stock Awards to receive payments therefor and (ii) as provided in Section 5.10, 5.13(e), 7.5 and 8.5 (each of which provisions is intended to be for the benefit of the Persons referred to therein, and may be enforced by any such Person), each of Parent and the Company hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other party hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein.  The parties hereto further agree that the rights of third party beneficiaries under Section 5.10 shall not arise unless and until the Effective Time occurs.  The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto.  Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 8.3 without notice or liability to any other Person.  Notwithstanding the foregoing, each Financing Source (and its Representatives) shall be express third party beneficiaries with respect to Sections 7.5(a),7.5(e) and 8.5.

8.10.                        Obligations of Parent and of the Company.  Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action.  Whenever this Agreement requires a Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Corporation to cause such Subsidiary to take such action.

8.11.                        Transfer Taxes.  All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including penalties and interest) imposed under applicable Law on the Parent and/or Merger Sub in connection with the Merger shall be paid by Parent and Merger Sub when due.
