(i) At the Effective Time, each then outstanding Company Option, including unvested Company Options, shall be cancelled, and (A) in the case of any Company Option that is vested in accordance with the terms of the applicable Company Stock Plan having a per share exercise price less than the Per Share Price, for the right to receive from the Surviving Corporation for each share of Company Common Stock subject to such Company Option immediately prior to the Effective Time, an amount (subject to any applicable withholding tax) in cash equal to the product of (x) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time and (y) the amount by which the Per Share Price exceeds the per share exercise price of such Company Option (the “Option Consideration”), or (B) in the case of any Company Option having a per share exercise price equal to or greater than the Per Share Price or any unvested Company Option, without the payment of cash or issuance of other securities in respect thereof. Parent shall, or shall cause the Company to, pay to holders of Company Options the Option Consideration, without interest thereon, less applicable Taxes required to be withheld with respect to such payments pursuant to this Section 2.7(e), as soon as reasonably practicable following the Effective Time. The cancellation of a Company Option as provided in the immediately preceding sentence shall be deemed a release of any and all rights the holder thereof had or may have had in respect of such Company Option.

(ii) Prior to the Effective Time, the Company shall take such actions as may be necessary to give effect to the transactions contemplated by this Section 2.7(e), including, but not limited to, satisfaction of the requirements of Rule 16b-3(e) under the Exchange Act.

(iii) Except as otherwise agreed to by the parties, (A) the Company Stock Plans shall terminate as of the Effective Time and the provisions in any other Employee Plan 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, and (B) the Company shall ensure that following the Effective Time no participant in the Company Option Plans or other Employee Plans shall have any right thereunder to acquire any equity securities of the Company, the Surviving Corporation or any Subsidiary thereof.

(iv) Prior to the Effective Time, the Company shall deliver to the holders of Company Options notices, in form and substance reasonably acceptable to Newco, setting forth such holders’ rights pursuant to this Agreement. The Company Board (or, if appropriate, any committee thereof administering the Company Option Plans) shall adopt such resolutions or take such other actions as may be required to effect the foregoing.

(a) Payment Agent. Prior to the Effective Time, Newco shall select a bank or trust company reasonably acceptable to the Company to act as the payment agent for the Merger (the “Payment Agent”).

(b) Exchange Fund. At the Effective Time, Newco shall deposit (or cause to be deposited) with the Payment Agent, for payment to the holders of shares of Company Common Stock pursuant to the provisions of this Article II, an amount of cash equal to the

aggregate consideration to which holders of Company Common Stock and holders of Company Stock-Based Awards and Company Options become entitled under this Article II. Until disbursed in accordance with the terms and conditions of this Agreement, Newco and the Surviving Corporation shall not permit such funds to be invested by the Payment Agent (such cash being referred to herein as the “Exchange Fund”). Any income from investment of the Exchange Fund, which shall be in accordance with the terms of this Agreement, will be payable to Newco or the Surviving Corporation, in Newco’s sole discretion.

(c) Payment Procedures. Promptly following the Effective Time, Newco and the Surviving Corporation shall cause the Payment Agent to mail to each holder of record (as of immediately prior to the Effective Time) of (i) a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented outstanding shares of Company Common Stock and (ii) uncertificated shares of Company Common Stock (the “Uncertificated Shares”) (A) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Payment Agent), and/or (B) instructions for use in effecting the surrender of the Certificates and Uncertificated Shares in exchange for the Per Share Price payable in respect thereof pursuant to the provisions of this Article II. Upon surrender of Certificates for cancellation to the Payment Agent or to such other agent or agents as may be appointed by Newco, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holders of such Certificates shall be entitled to receive in exchange therefor an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock represented by such Certificate, by (y) the Per Share Price (less any applicable withholding taxes payable in respect thereof), and the Certificates so surrendered shall forthwith be canceled. Upon receipt of an “agent’s message” by the Payment Agent (or such other evidence, if any, of transfer as the Payment Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the holders of such Uncertificated Shares shall be entitled to receive in exchange therefor an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock represented by such holder’s transferred Uncertificated Shares, by (y) the Per Share Price (less any applicable withholding taxes payable in respect thereof), and the transferred Uncertificated Shares so surrendered shall forthwith be canceled. The Payment Agent shall accept such Certificates and transferred Uncertificated Shares upon compliance with such reasonable terms and conditions as the Payment Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates and Uncertificated Shares on the Per Share Price payable upon the surrender of such Certificates and Uncertificated Shares pursuant to this Section 2.8. Until so surrendered, outstanding Certificates and Uncertificated Shares shall be deemed from and after the Effective Time, to evidence only the right to receive the Per Share Price, without interest thereon, payable in respect thereof pursuant to the provisions of this Article II.

(d) Transfers of Ownership. In the event that a transfer of ownership of shares of Company Common Stock is not registered in the stock transfer books or ledger of the Company, or if the Per Share Price is to be paid in a name other than that in which the Certificates or Uncertificated Shares surrendered in exchange therefor are registered in the stock transfer books or ledger of the Company, the Per Share Price may be paid to a Person other than

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

(e) Required Withholding. Each of the Payment Agent, Newco and the Surviving Corporation shall be entitled to deduct and withhold from any cash amounts payable pursuant to this Agreement to any holder or former holder of shares of Company Common Stock, Company Stock-Based Awards and Company Options such amounts as may be required to be deducted or withheld therefrom under U.S. federal or state, local or non-U.S. Tax laws. To the extent that such amounts are so deducted or withheld and paid over to the appropriate taxing authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Payment Agent, Newco, the Surviving Corporation or any other party hereto shall be liable to a holder of shares of Company Common Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

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

2.9 No Further Ownership Rights in Company Common Stock. From and after the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled, retired and cease to exist, and each holder of Uncertificated Shares or a Certificate theretofore representing any shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Per Share Price payable therefor in accordance with the provisions of Section 2.7. The Per Share Price paid in accordance with the

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

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

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

Except (i) as set forth in the disclosure schedule delivered by the Company to Newco on the date of this Agreement (the “Company Disclosure Letter”), or (ii) as disclosed in any Company SEC Reports filed by the Company with the SEC on or after December 31, 2007, and publicly available, prior to the date hereof (to the extent it is reasonably apparent that any such disclosure set forth in the Company SEC Reports would qualify the representations and warranties contained herein, and excluding (1) any exhibits thereto, (2) any items included therein that are incorporated by reference to Company SEC Reports filed prior to December 31, 2007 and (3) any risk factor disclosures or other cautionary, predictive or forward-looking disclosures contained therein), the Company hereby represents and warrants to Newco and Merger Sub as follows:

3.1 Organization; Good Standing. The Company is a corporation duly organized, validly existing and in good standing under Maryland Law, and has the requisite corporate power and authority to conduct its business as it is presently being conducted and to own, lease or operate its properties and assets, except where the failure to be in good standing would not have a Company Material Adverse Effect. The Company is duly qualified to do business and is in good standing in each jurisdiction where the character of its properties owned or leased or the nature of its activities make such qualification necessary (to the extent the “good standing” concept is applicable in the case of any jurisdiction outside the United States), except where the

failure to be so qualified or in good standing would not have, individually or in the aggregate, a Company Material Adverse Effect. The Company has delivered or made available to Newco complete and correct copies of the Charter and bylaws of the Company, each as amended to date. The Company is not in material violation of the Charter or its bylaws.

3.2 Corporate Power; Enforceability. The Company has the requisite corporate power and authority to execute and deliver this Agreement, to perform its covenants and obligations hereunder and, subject to receiving the Requisite Stockholder Approval, to consummate the Merger. The execution and delivery of this Agreement by the Company, the performance by the Company of its covenants and obligations hereunder and the consummation of the Merger have been duly authorized by all necessary corporate action on the part of the Company and no additional corporate proceedings on the part of the Company are necessary to authorize the execution and delivery of this Agreement by the Company, the performance by the Company of its covenants and obligations hereunder or, subject to the receipt of the Requisite Stockholder Approval, the consummation of the Merger. This Agreement has been duly executed and delivered by the Company and, assuming the due authorization, execution and delivery by Newco and Merger Sub, constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except that such enforceability (a) may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting or relating to creditors’ rights generally, and (b) is subject to general principles of equity.

(a) The Company Board has (i) determined that it is in the best interests of the Company and the Company Stockholders, and declared it advisable, to enter into this Agreement and consummate the Merger upon the terms and subject to the conditions set forth herein, (ii) approved the execution and delivery of this Agreement by the Company, the performance by this Company of its covenants and obligations hereunder and the consummation of the Merger upon the terms and conditions contained set forth herein, and (iii) resolved to recommend that the Company Stockholders approve the Merger in accordance with the applicable provisions of the MGCL (the “Company Board Recommendation”).

(b) The Company has received the opinion of Barclays Capital that, as of the date hereof and subject to the assumptions and qualifications set forth therein, the Per Share Price is fair from a financial point of view to the Company Stockholders, a copy of which opinion will be delivered to Newco solely for informational purposes after execution of this Agreement.

(c) Assuming that the representations of Newco and Merger Sub set forth in Section 4.7 are true and correct, the Company Board has taken all necessary actions such that the restrictions on business combinations set forth in Section 3-601 et. seq. of the MGCL and any other similar applicable “anti-takeover” law will not be applicable to the Merger.

3.4 Requisite Stockholder Approval. The affirmative vote of the holders of two-thirds the outstanding shares of Company Common Stock (the “Requisite Stockholder Approval”) is the only vote of the holders of any class or series of Company Capital Stock that is necessary under applicable law, the Charter and the Company’s bylaws to consummate the Merger.

3.5 Non-Contravention. The execution and delivery of this Agreement by the Company, the performance by the Company of its covenants and obligations hereunder and the consummation of the Merger do not and will not (i) violate or conflict with any provision of the Charter or bylaws of the Company, (ii) violate, conflict with, or result in the breach of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or result in the termination of, or accelerate the performance required by, or result in a right of termination or acceleration under, any Material Contract, (iii) assuming compliance with the matters referred to in Section 3.6 and, in the case of the consummation of the Merger, subject to obtaining the Requisite Stockholder Approval, violate or conflict with any law or order applicable to the Company or any of its Subsidiaries or by which any of their respective properties or assets are bound, or (iv) result in the creation of any lien upon any of the properties or assets of the Company or any of its Subsidiaries, except in the case of each of clauses (ii), (iii) and (iv) above, for such violations, conflicts, defaults, terminations, accelerations or liens which would not have, individually or in the aggregate, a Company Material Adverse Effect.

3.6 Requisite Governmental Approvals. No consent, approval, order or authorization of, filing or registration with, or notification to (any of the foregoing being referred to herein as a “Consent”), any Governmental Authority is required on the part of the Company in connection with the execution and delivery of this Agreement by the Company, the performance by the Company of its covenants and obligations hereunder or the consummation of the Merger, except (i) the filing and recordation of the Articles of Merger with the Maryland Department of Assessments and Taxation, (ii) such filings and approvals as may be required by any federal or state securities laws, including compliance with any applicable requirements of the Exchange Act, and (iii) compliance with any applicable requirements of the HSR Act and any applicable foreign Antitrust Laws.

Each outstanding Company Option has an exercise price equal to or greater than the fair market value of the underlying shares of Company Common Stock as of the date of grant. All outstanding shares of Company Common Stock have been, and all shares that may be issued pursuant to any Company Stock Plan will be, when issued in accordance with the respective terms thereof, duly authorized and validly issued and are (or, in the case of shares that have not yet been issued, will be) fully paid, nonassessable and free of preemptive rights.

of each Subsidiary of the Company. Each of the Subsidiaries of the Company is duly organized, validly existing and in good standing under the laws of the jurisdiction of its respective organization (to the extent the “good standing” concept is applicable in the case of any jurisdiction outside the United States). Each of the Subsidiaries of the Company has the requisite corporate power and authority to carry on its respective business as it is presently being conducted and to own, lease or operate its respective properties and assets, except where the failure to be in good standing would not have a Company Material Adverse Effect. Each of the Subsidiaries of the Company is duly qualified to do business and is in good standing in each jurisdiction where the character of its properties owned or leased or the nature of its activities make such qualification necessary (to the extent the “good standing” concept is applicable in the case of any jurisdiction outside the United States), except where the failure to be so qualified or in good standing would not have, individually or in the aggregate, a Company Material Adverse Effect.

(c) Except as set forth in this Section 3.8, there are (i) no outstanding securities of, or other equity or voting interest in, any Subsidiary of the Company, (ii) no outstanding securities of any Subsidiary of the Company convertible into or exchangeable for shares of capital stock of, or other equity or voting interest in, any Subsidiaries of the Company, (iii) no outstanding options, warrants or other rights or arrangements obligating the Company or any of its Subsidiaries to acquire from any Subsidiaries of the Company, or that obligates or commits any Subsidiaries of the Company to issue, any capital stock of, or other equity or voting interest in, or any securities convertible into or exchangeable for shares of capital stock of, or other equity or voting interest in, any Subsidiaries of the Company, (iv) no obligations of any Subsidiaries of the Company to grant, extend or enter into any subscription, warrant, right, convertible or exchangeable security or other similar Contract relating to any capital stock of, or other equity or voting interest (including any voting debt) in, any Subsidiaries of the Company, (v) no outstanding restricted shares, restricted share units, stock appreciation rights, performance shares, contingent value rights, “phantom” stock or similar securities or rights that are derivative of, or provide economic benefits based, directly or indirectly, on the value or price of, any capital stock of, or other voting securities or ownership interests in, any Subsidiary of the Company (the items in clauses (i), (ii), (iii), (iv) and (v), together with the capital stock of the Subsidiaries of the Company, being referred to collectively as “Subsidiary Securities”), (vi) voting trusts, proxies or other similar agreements or understandings to which any Subsidiary of the Company is a party or by which any Subsidiary of the Company is bound with respect to the voting of any shares of capital stock of any Subsidiary of the Company, (vii) obligations or commitments of any character restricting the transfer of any shares of capital stock of any Subsidiary of the

3.9 Company SEC Reports. The Company has filed all forms, reports and documents with the SEC that have been required to be filed by it under applicable laws prior to the date hereof, and the Company will file prior to the Effective Time all forms, reports and documents with the SEC that are required to be filed by it under applicable laws prior to such time (all such forms, reports and documents, together with all exhibits and schedules thereto, the “Company SEC Reports”). Each Company SEC Report complied, or will comply, as the case may be, as of its filing date, in all material respects with the applicable requirements of the Securities Act or the Exchange Act, as the case may be, each as in effect on the date such Company SEC Report was, or will be, filed. True and correct copies of all Company SEC Reports filed prior to the date hereof have been furnished to Newco or are publicly available in the Electronic Data Gathering, Analysis and Retrieval (EDGAR) database of the SEC. As of its filing date (or, if amended or superseded by a filing prior to the date of this Agreement, on the date of such amended or superseded filing), each Company SEC Report did not and will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. None of the Company’s Subsidiaries is required to file any forms, reports or other documents with the SEC. No executive officer of the Company has failed to make the certifications required of him or her under Section 302 or 906 of the Sarbanes-Oxley Act with respect to any Company SEC Report, except as disclosed in certifications filed with the Company SEC Reports, and, at the time of filing or submission of each such certification, such certification was true and accurate.

There are no unconsolidated Subsidiaries of the Company. The Company’s financial statements referred to above accurately reflect all compensation expenses required to be reflected thereon as a result of any misdating or other inappropriate granting of any Company Options.

(b) The Company has established and maintains, adheres to and enforces a system of internal accounting controls which are sufficient to provide reasonable assurance

regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP, including policies and procedures that (i) require the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company and its Subsidiaries, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company and its Subsidiaries are being made only in accordance with appropriate authorizations of management and the Company Board and (iii) provide assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the assets of the Company and its Subsidiaries. Neither the Company nor, to the Knowledge of the Company, the Company’s independent auditors, has identified or been made aware of (A) any significant deficiency or material weakness in the system of internal accounting controls utilized by the Company and its Subsidiaries, in each case which has not been subsequently remediated, or (B) any fraud that involves the Company’s management or other employees who have a role in the preparation of financial statements or the internal accounting controls utilized by the Company and its Subsidiaries.

(c) The Company has adopted a code of ethics, as defined by Item 406(b) of Regulation S-K, for senior financial officers, applicable to its principal financial officer, comptroller or principal accounting officer, or Persons performing similar functions.

To the Knowledge of the Company, since the adoption of the code of ethics, there have been no violations of provisions of the Company’s code of ethics by any such Persons.

(d) Neither the Company nor any of its Subsidiaries is a party to any joint venture, partnership agreement or any similar Contract (including any Contract relating to any transaction, arrangement or relationship between or among the Company or any of its Subsidiaries, on the one hand, and any unconsolidated affiliate, including any structured finance, special purpose or limited purpose entity or Person, on the other hand (such as any arrangement described in Section 303(a)(4) of Regulation S-K of the SEC)) where the purpose or effect of such Contract is to avoid disclosure of any material transaction involving the Company or any its Subsidiaries in the Company’s consolidated financial statements.

3.11 No Undisclosed Liabilities. Neither the Company nor any of its Subsidiaries has any liabilities, other than (a) liabilities reflected or otherwise reserved against in the Audited Company Balance Sheet, (b) liabilities arising under this Agreement or incurred in connection with the transactions contemplated by this Agreement, (c) liabilities arising under executory Contracts to which the Company or any of its Subsidiaries is a party or otherwise bound, (d) liabilities incurred in the ordinary course of business consistent with past practice, and (e) liabilities that would not have a Company Material Adverse Effect.

(a) Since December 31, 2008 through the date hereof, except for actions expressly contemplated by this Agreement or disclosed in the Company SEC Reports filed since December 31, 2008 (other than (i) any exhibits thereto, (ii) any items included therein that are incorporated by reference to Company SEC Reports filed prior to December 31, 2007 and (iii)

any risk factor disclosures or other cautionary, predictive or forward-looking disclosures contained therein), the business of the Company and its Subsidiaries has been conducted, in all material respects, in the ordinary course consistent with past practice, and there has not been or occurred any Company Material Adverse Effect that is continuing.

(b) Since December 31, 2008 through the date hereof, the Company has not taken any action that would be prohibited by Section 5.2 if proposed to be taken after the date hereof.

(a) For all purposes of and under this Agreement, a “Material Contract” shall mean any of the following:

(i) any “material contract” (as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC, other than those agreements and arrangements described in Item 601(b)(10)(iii)) with respect to the Company and its Subsidiaries, taken as whole;

(ii) any employment or consulting Contract (in each case, under which the Company has continuing obligations as of the date hereof) with any current or former executive officer or other employee of the Company or its Subsidiaries or member of the Company Board providing for an annual base salary in excess of $150,000;

Neither Newco, Merger Sub nor any of their respective Affiliates, partners, members, stockholders, directors, officers or employees own any shares of Company Common Stock.

4.8 Brokers. No agent, broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission payable by the Company in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of Newco or Merger Sub.

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

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

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

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

4.11 Management Arrangements. As of the date hereof, except as previously disclosed to the Company Board, there are no Contracts or any formal or informal arrangements or other

understandings (whether or not binding) between Newco, Merger Sub or any of their respective Affiliates, on the one hand, and any director or officer of the Company, on the other hand, relating to this Agreement, the Merger or any other transactions contemplated by this Agreement (including as to any investments to be made in, or contributions to be made to, Newco or Merger Sub), or to the Surviving Corporation or any of its Subsidiaries, businesses or operations (including as to continuing employment) from and after the Closing.

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

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

documents, estimates, projections, forecasts or other forward-looking information, business plans or other material provided or made available to Newco, Merger Sub or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, in “data rooms,” confidential information memoranda or management presentations in anticipation or contemplation of the Merger or any other transactions contemplated by this Agreement. Notwithstanding the foregoing, nothing in this Section 4.13 or this Agreement shall relieve any Person of liability for fraud or willful misconduct or prevent Newco and Merger Sub from relying on the representations and warranties of the Company set forth in this Agreement or the other agreements or certificates entered into or delivered by the Company in connection with this Agreement.

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

Newco and Merger Sub hereby acknowledge that there are uncertainties inherent in attempting to make such estimates, projections, forecasts and other forward-looking statements, as well as in such business plans, and that Newco and Merger Sub will have no claim against the Company or any of its Subsidiaries, or any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, or any other Person, with respect thereto. Accordingly, Newco and Merger Sub hereby acknowledge and agree that none of the Company or any of its Subsidiaries, nor any of their respective Affiliates, stockholders, directors, officers, employees, agents, representatives or advisors, nor any other Person, has made or is making any express or implied representation or warranty with respect to such estimates, projections, forecasts, forward-looking statements or business plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, forward-looking statements or business plans). Notwithstanding the foregoing, nothing in this Section 4.14 or this Agreement shall relieve any Person of liability for fraud or willful misconduct or prevent Newco and Merger Sub from relying on the representations and warranties of the Company set forth in this Agreement or the other agreements or certificates entered into or delivered by the Company in connection with this Agreement.

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

(e) Other than with respect to the Commitment Letters, neither Newco or Merger Sub, or any of their respective Affiliates, shall enter into any Contracts with any Person, or make or enter into any formal or informal arrangements or understanding (whether or not binding) with any Person, or have any discussions or other communications with any other Person, in any such case with respect to any actual or potential Acquisition Proposal involving the Company.

(a) Upon the terms and subject to the conditions set forth in this Agreement, Newco and Merger Sub, on the one hand, and (subject to the Company’s rights under Section 6.3, Section 6.4 and Section 6.5) the Company, on the other hand, shall take (or cause to be taken) all actions reasonably necessary, and do (or cause to be done), and assist and cooperate with the other party or parties hereto in doing, all things reasonably necessary, proper or advisable under applicable law or otherwise to consummate and make effective, in the most expeditious manner practicable, the Merger, including by:

(b) In addition to the foregoing, neither Newco or Merger Sub, on the one hand, nor the Company, on the other hand, shall take any action, or fail to take any action, that is intended to, or has (or would reasonably be expected to have) the effect of, preventing, impairing, delaying or otherwise adversely affecting the consummation of the Merger or the ability of such party to fully perform its obligations under this Agreement.

(c) The Company shall repatriate cash to bank accounts in the United States as reasonably requested by Newco and Merger Sub.

(d) Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, the Company shall be responsible for using (and causing its Subsidiaries to use) their respective reasonable best efforts to prepare and file the necessary notices, reports or other filings and to obtain the consents, approvals and authorizations identified or required to be

identified in Section 3.5 or Section 3.6 or in the related section of the Company Disclosure Letter (which, in the case of the consents, approvals and notifications identified or required to be identified in Section 3.6 or in the related section of the Company Disclosure Letter, are required to be obtained by the Company), and Newco and Merger Sub shall be responsible for using their respective commercially reasonable efforts to cooperate with the Company in preparing and filing such notices, reports or other filings and obtaining such consents, approvals and authorizations.

(e) Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, Newco and Merger Sub shall be responsible for using their respective reasonable best efforts to prepare and file the necessary notices, reports or other filings and to obtain the consents, approvals and authorizations identified or required to be identified in Section 4.3 or Section 4.4 or in a disclosure schedule relating thereto (which, in the case of the consents, approvals and notifications identified or required to be identified in Section 4.4 or in a disclosure schedule relating thereto, are required to be obtained by Newco and/or Merger Sub), and the Company shall be responsible for using its commercially reasonable efforts to cooperate with Newco and Merger Sub in preparing and filing such notices, reports or other filings and obtaining such consents, approvals and authorizations.

6.2 Antitrust Filings. Each of Newco and Merger Sub (and their respective Affiliates, if applicable), on the one hand, and the Company, on the other hand, shall (i) file with the FTC and the Antitrust Division of the DOJ a Notification and Report Form relating to this Agreement and the transactions contemplated hereby as required by the HSR Act within ten (10) calendar days following the execution and delivery of this Agreement, and (ii) file comparable pre-merger or post-merger notification filings, forms and submissions with any foreign Governmental Authority that are required by the other applicable Antitrust Laws in connection with the Merger.

Each of Newco and Merger Sub (and their respective Affiliates, if applicable), on the one hand, and the Company, on the other hand, shall promptly inform the other of any communication from any Governmental Authority regarding any of the transactions contemplated by this Agreement in connection with such filings. If any party hereto or Affiliate thereof shall receive a request for additional information or documentary material from any Governmental Authority with respect to the transactions contemplated by this Agreement pursuant to the HSR or any other Antitrust Laws applicable to the Merger with respect to which any such filings have been made, then such party shall make (or cause to be made), as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request.

(a) As soon as practicable following the date hereof (and in any event within ten (10) Business Days), the Company shall prepare and file with the SEC, the Proxy Statement for use in connection with the solicitation of proxies from the Company Stockholders for use at the Company Stockholder Meeting. If the Company determines that it is required to file with the SEC any Other Required Company Filing under applicable law, the Company shall promptly prepare and file with the SEC such Other Required Company Filing. If Newco, Merger Sub or any of their respective Affiliates determine that they are required to file any Other Required Newco Filing under applicable law, then Newco, Merger Sub and their respective Affiliates, if applicable, shall promptly prepare and file with the SEC such Other Required Newco Filing. The Company shall cause the Proxy Statement and any Other Required Company Filing to comply as to form and substance in all material respects with the applicable requirements of the Exchange Act and the rules of the SEC and Nasdaq. Newco and Merger Sub shall cause any Other Required Newco Filing to comply as to form and substance in all material respects with the applicable requirements of the Exchange Act and the rules of the SEC. The Company, Newco and Merger Sub, as the case may be, shall furnish all information concerning the Company, on the one hand, and Newco and Merger Sub (and their respective Affiliates, if applicable), on the other hand, as the other may reasonably request in connection with the preparation and filing with the SEC of the Proxy Statement, any Other Required Company Filing and any Other Required Newco Filing. If at any time prior to the Company Stockholder Meeting, any information relating to the Company, Newco or Merger Sub, or any of their respective partners, members, stockholders, directors, officers or other Affiliates, should be discovered by the Company, Newco or Merger Sub which should be set forth in an amendment or supplement to the Proxy Statement, any Other Required Company Filing or any Other Required Newco Filing, as the case may be, so that the Proxy Statement, any Other Required Company Filing or Other Required Newco Filing, as the case may be, would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other, and an appropriate amendment or supplement to the Proxy Statement or the applicable Other Required Company Filing or Other Required Newco Filing describing such information shall be promptly prepared and filed with the SEC and, to the extent required by applicable law or the SEC or its staff, disseminated to the Company Stockholders.

(b) Subject to applicable law, the Company shall use reasonable best efforts to cause the Proxy Statement to be disseminated to the Company Stockholders as promptly as practicable following the filing thereof with the SEC and confirmation from the SEC that it will not comment on, or that it has no additional comments on, the Proxy Statement, any Other Required Company Filing and any Other Required Newco Filing.

(c) Unless the Company Board or any authorized committee thereof shall have effected a Company Board Recommendation Change pursuant to the terms of Section 6.5(a), (i) the Company and its Affiliates, on the one hand, and Newco, Merger Sub and their respective Affiliates, on the other hand, shall not file with the SEC the Proxy Statement, any Other Required Company Filing or any Other Required Newco Filing, as the case may be, or any amendment or supplement thereto, and (ii) the Company and its Affiliates, on the one hand, and Newco, Merger Sub and their respective Affiliates, on the other hand, shall not correspond or otherwise communicate with the SEC or its staff with respect to the Proxy Statement, any

Other Required Company Filing or any Other Required Newco Filing, as the case may be, in any such case referenced in the preceding clause (i) or (ii) without providing the other a reasonable opportunity to review and comment thereon or participate therein, as the case may be.

(d) Unless the Company Board or any authorized committee thereof shall have effected a Company Board Recommendation Change pursuant to the terms of Section 6.5(a), the Company, on the one hand, and Newco and Merger Sub, on the other hand, shall advise the other, promptly after it receives notice thereof, of any receipt of a request by the SEC or its staff for an amendment or revisions to the Proxy Statement, any Other Required Company Filing or any Other Required Newco Filing, as the case may be, any receipt of comments from the SEC or its staff on the Proxy Statement, any Other Required Company Filing or any Other Required Newco Filing, as the case may be, or any receipt of a request by the SEC or its staff for additional information in connection therewith.

(e) Unless the Company Board or any authorized committee thereof shall have effected a Company Board Recommendation Change in accordance with the terms of Section 6.5(a), the Company shall include the Company Board Recommendation in the Proxy Statement and, if applicable, any Other Required Company Filings.

(a) The Company shall establish a record date for, call, give notice of, convene and hold a meeting of the Company Stockholders (or any adjournment or postponement thereof, the “Company Stockholder Meeting”) as promptly as reasonably practicable following the date hereof (and in any event, subject to the immediately following proviso, no later than thirty (30) calendar days immediately following the date on which the SEC confirms that it will not comment on, or that it has no additional comments on, the Proxy Statement, any Other Required Company Filing and any Other Required Newco Filing) for the purpose of voting to approve the Merger in accordance with the MGCL; provided, however, nothing herein shall prevent the Company from postponing or adjourning the Company Stockholder Meeting if (i) there are holders of insufficient shares of the Company Common Stock present or represented by a proxy at the Company Stockholder Meeting to constitute a quorum at the Company Stockholder Meeting, (ii) the Company is required to postpone or adjourn the Company Stockholder Meeting by applicable law, order or a request from the SEC or its staff, or (iii) the Company Board or any authorized committee thereof shall have determined in good faith (after consultation with outside legal counsel) that it is necessary or appropriate to postpone or adjourn the Company Stockholder Meeting, including in order to (A) give Company Stockholders sufficient time to evaluate any information or disclosure that the Company has sent to Company Stockholders or otherwise made available to Company Stockholders by issuing a press release, filing materials with the SEC or otherwise (including in connection with any Company Board Recommendation Change), or (B) to enable the additional time to solicit proxies from Company Stockholders.

(b) Unless the Company Board or any authorized committee thereof shall have effected a Company Board Recommendation Change pursuant to the terms of Section 6.5(a), the Company shall solicit from the Company Stockholders proxies in favor of the approval of the Merger in accordance with Maryland Law, submit the Merger for approval of the Company Stockholders at the Company Stockholder Meeting and use its reasonable best efforts to secure the Requisite Stockholder Vote at the Company Stockholder Meeting.

(a) Neither the Company Board nor any committee thereof shall withhold, withdraw, amend or modify in a manner adverse to Newco in any material respect, or publicly propose to withhold, withdraw, amend or modify in a manner adverse to Newco in any material respect, the Company Board Recommendation (a “Company Board Recommendation Change”); provided, however, that a “stop, look and listen” communication by the Company Board or any authorized committee thereof to the Company Stockholders pursuant to Rule 14d-9(f) of the Exchange Act, or any substantially similar communication, shall not be deemed to be a Company Board Recommendation Change; and provided further, that notwithstanding the foregoing or anything to the contrary set forth in this Agreement (including the provisions of Section 6.1), at any time prior to the receipt of the Requisite Stockholder Approval, the Company Board and/or any authorized committee thereof may effect a Company Board Recommendation Change if the Company Board and/or any authorized committee thereof shall have determined in good faith (after consultation with outside legal counsel) that the failure to effect a Company Board Recommendation Change would reasonably be expected to be a breach of its fiduciary duties under applicable law.

(b) Nothing in this Agreement shall prohibit the Company Board or any authorized committee thereof from (i) taking and disclosing to the Company Stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act or complying with the provisions of Rule 14d-9 promulgated under the Exchange Act, and (ii) making any disclosure to the Company Stockholders that the Company Board or any authorized committee thereof shall have determined to make in good faith (after consultation with its outside legal counsel) in order to comply with its fiduciary duties under applicable law; provided, however, that, in either such case, any such statement(s) or disclosures made by the Company Board or any authorized committee thereof shall be subject to the terms and conditions of this Agreement, including the provisions of Article VIII.

(a) Newco and Merger Sub shall take (or cause to be taken) all actions, and do (or cause to be done) all things, necessary, proper or advisable to obtain the Equity Financing contemplated by the Equity Commitment Letter, including (i) maintaining in effect the Equity Commitment Letter, (ii) satisfying on a timely basis all conditions applicable to Newco and Merger Sub set forth in the Equity Commitment Letter that are within their control, (iii) consummating the Equity Financing contemplated by the Equity Commitment Letter at or prior to the Closing (and in any event prior to the Termination Date), and (iv) subject to the immediately following sentence of this Section 6.6(a), fully enforcing the Investor’s obligations (and the rights of Newco and Merger Sub) under the Equity Commitment Letter, including (at the request of the Company) by filing one or more lawsuits against the Investor to fully enforce the Investor’s obligations (and the rights of Newco and Merger Sub) thereunder or assigning the rights of Newco and Merger Sub to bring such lawsuits to the Company so as to enable the Company to file such lawsuits against the Investor on behalf of Newco and Merger Sub.

(b) Neither Newco nor Merger Newco shall amend, alter, or waive, or agree to amend, alter or waive (in any case whether by action or inaction), any term of the Equity Commitment Letter without the prior written consent of the Company. Newco shall promptly (and in any event within one Business Day) notify the Company of (i) the expiration or termination (or attempted or purported termination, whether or not valid) of the Equity Commitment Letter, or (ii) any refusal by the Investor to provide, any stated intent by the Investor to refuse to provide, or any expression of concern or reservation by the Investor regarding its obligation and/or ability to provide, the full financing contemplated by the Equity Commitment Letter.

(a) Newco and Merger Sub shall use their respective commercially reasonable efforts to obtain the Debt Financing on the terms and conditions set forth in the Debt Commitment Letter (or terms not materially less favorable to Newco or the Company (including with respect to the conditionality thereof)), including (i) maintaining in effect the Debt Commitment Letter and negotiating definitive agreements with respect to the Debt Commitment Letter on the terms and conditions set forth in the Debt Commitment Letter (or on terms not materially less favorable to Newco or Merger Sub than the terms and conditions in the Debt Commitment Letter), (ii) satisfying on a timely basis all conditions applicable to Newco and Merger Sub set forth in such definitive agreements that are within their reasonable control, and (iii) consummating the Debt Financing contemplated by the Debt Commitment Letter at or prior to the Closing (and in any event prior to the Termination Date). In the event that all conditions in the Debt Commitment Letter (other than the availability of funding of any of the Equity Financing) have been satisfied or, upon funding will be satisfied, Newco and Merger Sub shall use their commercially reasonable efforts to cause such lenders and the other Persons providing such Debt Financing to fund on the Closing Date the Debt Financing required to consummate the transactions contemplated by this Agreement and otherwise enforce its rights under the Debt Commitment Letter. Nothing herein or in the Debt Commitment Letter shall adversely affect the obligation of Newco and Merger Sub to ensure that the Equity Financing contemplated by the Equity Commitment Letter is sufficient to fully finance the Merger and the other transactions contemplated by this Agreement.

(b) Neither Newco nor Merger Newco shall amend, alter, or waive, or agree to amend, alter or waive (in any case whether by action or inaction), any term of the Debt Commitment Letter without the prior written consent of the Company if such amendment, alteration or waiver reduces the aggregate amount of the Debt Financing or amends the conditions precedent to the Debt Financing in a manner that would reasonably be expected to delay or prevent the Closing Date or make the funding of the Debt Financing less likely to occur; provided, however, that Newco and Merger Sub may replace and/or amend the Debt Commitment Letter so long as (i) the terms are not materially less favorable to Newco or the Company, including with respect to conditionality thereof, and (ii) the conditions to the Debt Financing set forth in the Debt Commitment Letter as of the date hereof would not be materially expanded in a manner that would reasonably be expected to delay or prevent the Closing; and in any such event Newco shall disclose to the Company its intention to obtain such alternative financing, shall keep the Company informed of the terms thereof and shall deliver to the Company final drafts of the commitment letter (the “New Debt Commitment Letter”) providing

for such alternative financing and, if requested to do so, the Company shall within a reasonable time (and in no event more than three (3) Business Days thereafter) inform Newco as to whether it agrees that such alternative financing is on terms not materially less favorable (including, with respect to the conditionality thereof) to the Company than the Debt Commitment Letter. If the Company so agrees, the term “Debt Financing” as used herein shall be deemed to mean the Debt Financing contemplated by the Debt Commitment Letter to the extent not so superseded at the time in question and the New Debt Commitment Letter to the extent then in effect. Newco shall promptly (and in any event within one Business Day) notify the Company of the expiration or termination (or attempted or purported termination, whether or not valid) of the Debt Commitment Letter.

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

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

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

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

(a) The Surviving Corporation and its Subsidiaries shall honor and fulfill in all respects the obligations of the Company and its Subsidiaries under any and all

indemnification agreements between the Company or any of its Subsidiaries and any of their respective current or former directors and officers and any person who becomes a director or officer of the Company or any of its Subsidiaries prior to the Effective Time (the “Indemnified Persons”). In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation and its Subsidiaries shall (and the Surviving Corporation shall cause its Subsidiaries to) cause the charters and bylaws (and other similar organizational documents) of the Surviving Corporation and its Subsidiaries to contain provisions with respect to indemnification, exculpation and the advancement of expenses that are at least as favorable as the indemnification, exculpation and advancement of expenses provisions set forth in the Charter and bylaws (or other similar organizational documents) of the Company and its Subsidiaries as of the date hereof, and during such six-year period such provisions shall not be repealed, amended or otherwise modified in any manner except as required by applicable law.

(b) Without limiting the generality of the provisions of Section 6.11(a), during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall indemnify and hold harmless each Indemnified Person from and against any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, proceeding, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such claim, proceeding, investigation or inquiry arises directly or indirectly out of or pertains directly or indirectly to (i) any action or omission or alleged action or omission in such Indemnified Person’s capacity as a director, officer, employee or agent of the Company or any of its Subsidiaries or other Affiliates (regardless of whether such action or omission, or alleged action or omission, occurred prior to, at or after the Effective Time), or (ii) any of the transactions contemplated by this Agreement; provided, however, that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Person delivers to the Surviving Corporation a written notice asserting a claim for indemnification under this Section 6.11(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In the event of any such claim, proceeding, investigation or inquiry, (i) the Surviving Corporation shall have the right to control the defense thereof after the Effective Time (it being understood that, by electing to control the defense thereof, subject to the terms and conditions of this Section 6.11(b) (including, without limitation, the right of the Surviving Corporation to dispute that an Indemnified Person is entitled to indemnification pursuant to this Section 6.11), the Surviving Corporation will be deemed to have waived any right to object to the Indemnified Person’s entitlement to indemnification hereunder with respect thereto), (ii) each Indemnified Person shall be entitled to retain his or her own counsel, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry, (iii) the Surviving Corporation shall only be required to pay the reasonable fees and expenses of any counsel if the Surviving Corporation elects not to control the defense of any such claim, proceeding, investigation or inquiry, other than any fees and expenses of such separate counsel that are incurred prior to the date upon which the Surviving Corporation effectively assumes control of such defense (which, notwithstanding the foregoing, shall be borne and paid for by the Surviving Corporation) and (iv) no Indemnified Person shall be liable for any settlement effected without his or her prior express written consent. Notwithstanding

anything to the contrary set forth in this Section 6.11(b) or elsewhere in this Agreement, neither the Surviving Corporation nor any of its Affiliates (including Newco) shall settle or otherwise compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, proceeding, investigation or inquiry for which indemnification may be sought by an Indemnified Person under this Agreement unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Persons from all liability arising out of such claim, proceeding, investigation or inquiry. Notwithstanding anything to the contrary set forth in this Section 6.11(b) or elsewhere in this Agreement, in no event shall the Surviving Corporation or any of its Affiliates (including Newco) have any obligation to indemnify and hold harmless any Indemnified Person with respect to any claim, proceeding, investigation, inquiry or other matter if such indemnification is prohibited by applicable law.

(c) During the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) maintain in effect the Company’s current directors’ and officers’ liability insurance (“D&O Insurance”) in respect of acts or omissions occurring at or prior to the Effective Time, covering each person covered by the D&O Insurance, on terms with respect to the coverage and amounts that are equivalent to those of the D&O Insurance; provided, however, that in satisfying its obligations under this Section 6.11(c), the Surviving Corporation shall not be obligated to pay annual premiums in excess of two hundred percent (200%) of the amount paid by the Company for coverage for its last full fiscal year (such two hundred percent (200%) amount, the “Maximum Annual Premium”) (which premiums the Company represents and warrants to be as set forth in Section 6.11(c) of the Company Disclosure Letter); provided, however, that that if the annual premiums of such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase a six-year “tail” prepaid policy on the D&O Insurance at a price not to exceed the Maximum Annual Premium. In the event that the Company elects to purchase such a “tail” policy prior to the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) maintain such “tail” policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other obligations of the Surviving Corporation (and Newco) under the first sentence of this Section 6.11(c) for so long as such “tail” policy shall be maintained in full force and effect.

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

(e) The obligations set forth in this Section 6.11 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Person (or any other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives)) without the prior written consent of such affected Indemnified Person or other person who is a beneficiary under the D&O Insurance or

the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives). Each of the Indemnified Persons or other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives) are intended to be third party beneficiaries of this Section 6.11, with full rights of enforcement against the Surviving Corporation (and Newco) as if a party thereto. The rights of the Indemnified Persons (and other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 6.11(c) (and their heirs and representatives)) under this Section 6.11 shall be in addition to, and not in substitution for, any other rights that such persons may have under the charters, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Company or any of its Subsidiaries, or applicable law (whether at law or in equity).

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

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

(b) The Surviving Corporation or one of its Subsidiaries shall (and Newco shall cause the Surviving Corporation or one of its Subsidiaries to), offer employment by the Surviving Corporation or one of its Subsidiaries to all employees of the Company and its Subsidiaries as of the Effective Time by taking such actions as required under applicable law, including by offering to enter into an offer letter and/or related agreement (or similar document as appropriate) with such employees. For a period of six months following the Effective Time, the Surviving Corporation shall (and Newco shall cause the Surviving Corporation to) either (i) maintain for the benefit of each Continuing Employee the Continuing Plans (but excluding equity based benefits, any bonus or incentive plans, and individual employment agreements) at benefit levels that are no less than those in effect at the Company or its Subsidiaries on the date of this Agreement other than equity based benefits, any bonus or incentive plans, and individual employment agreements, or (ii) provide compensation, and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) to each Continuing Employee that, taken as a whole, are no less favorable in the aggregate than the compensation and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) provided to such Continuing Employee immediately prior to the Effective Time (“Comparable Plans”), or (iii) provide some combination of (i) and (ii) above such that each Continuing Employee receives compensation and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) that, taken

as a whole, are no less favorable in the aggregate than the compensation and benefits (other than equity based benefits, any bonus or incentive plans, and individual employment agreements) provided to such Continuing Employee immediately prior to the Effective Time.

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

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

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

(b) The parties hereto hereby agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties hereto acknowledge and hereby agree that in the event of any breach or threatened breach by the Company, on the one hand, or Newco and Merger Sub, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Equity Commitment Letter or the Guarantee, the Company, on the one hand, and Newco and Merger Sub, on the other hand, shall be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement, the Equity Commitment Letter and the Guarantee by the other (as applicable), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement, the Equity Commitment Letter and the Guarantee, and this right shall include the right of the Company to cause Newco and Merger Sub to fully enforce the terms of the Equity Commitment letter against the Investor to the fullest extent permissible pursuant to the Equity Commitment Letter and applicable laws and to thereafter cause the Merger to be consummated. Newco and Merger Sub hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by Newco or Merger Sub, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of Newco and Merger Sub under this Agreement. The parties hereto further agree that (x) by seeking the remedies provided for in this Section 9.8(b), a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement, the Equity Commitment Letter or the Guarantee (including monetary damages) in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 9.8(b) are not available or otherwise are not granted, and (y) nothing set forth in this Section 9.8(b) shall require any party hereto to institute any proceeding for (or limit any party’s right to institute any proceeding for) specific performance under this Section 9.8(b) prior or as a condition to exercising any termination right under Article VIII (and pursuing damages after such termination), nor shall the commencement of any Legal Proceeding pursuant to this Section 9.8(b) or anything set forth in this Section 9.8(b) restrict or limit any party’s right to terminate this Agreement in accordance with the terms of Article VIII or pursue any other remedies under this Agreement, the Equity Commitment Letter or the Guarantee that may be available then or thereafter. Notwithstanding anything set forth herein to the contrary, from and after the Effective Time, none of the Company, its Affiliates, or their respective current or former directors, officers or employees shall be entitled to seek or recover monetary or other damages or relief (including equitable relief) against

Newco, the Surviving Corporation, the Guarantor, the Investor or any of their respective Affiliates in connection with this Agreement or the transactions contemplated hereby, except for claims to receive merger consideration pursuant to Section 9.6(c). If any Legal Proceedings seeking monetary or other damages or relief (including equitable relief) instituted by the Company or its Affiliates against Newco, Merger Sub, the Guarantor, the Investor or any of their respective Affiliates are pending as of the Effective Time, the Company shall cause such Legal Proceedings to be dismissed with prejudice as of the Effective Time.

9.9 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.

9.10 Consent to Jurisdiction. Each of the parties hereto (a) irrevocably consents to the service of the summons and complaint and any other process in any action or proceeding relating to the transactions contemplated by this Agreement, the Equity Commitment Letter and the Guarantee, for and on behalf of itself or any of its properties or assets, in accordance with Section 9.10 or in such other manner as may be permitted by applicable law, and nothing in this Section 9.10 shall affect the right of any party to serve legal process in any other manner permitted by applicable law, (b) irrevocably and unconditionally consents and submits itself and its properties and assets in any action or proceeding to the exclusive general jurisdiction of the State courts located within the State of Delaware (or, only if a State court located in the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware) in the event any dispute or controversy arises out of this Agreement, the Equity Commitment Letter, the Guarantee or the transactions contemplated hereby or thereby, the Equity Commitment Letter, the Guarantee, or for recognition and enforcement of any judgment in respect thereof, (c) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (d) agrees that any actions or proceedings arising in connection with this Agreement, the Equity Commitment Letter, the Guarantee or the transactions contemplated hereby or thereby shall be brought, tried and determined only in the state courts of the State of Delaware (or, only if the Delaware Court of Chancery state courts of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware), (e) waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same and (f) agrees that it will not bring any action relating to this Agreement, the Equity Commitment Letter, the Guarantee or the transactions contemplated hereby or thereby in any court other than the aforesaid courts. Each of Newco, Merger Sub and the Company agrees that a final judgment in any action or proceeding in such courts as provided above shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law.

9.11 WAIVER OF JURY TRIAL. EACH OF NEWCO, COMPANY AND MERGER SUB HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE COMMITMENT LETTER, THE GUARANTEE OR THE ACTIONS OF NEWCO, COMPANY OR MERGER SUB IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF OR THEREOF.

9.12 Company Disclosure Letter References. The parties hereto agree that the disclosure set forth in any particular section or subsection of the Company Disclosure Letter shall be deemed to be an exception to (or, as applicable, a disclosure for purposes of) (i) the representations and warranties (or covenants, as applicable) of the Company that are set forth in the corresponding section or subsection of this Agreement, and (ii) any other representations and warranties (or covenants, as applicable) of the Company that are set forth in this Agreement, but in the case of this clause (ii) only if the relevance of that disclosure as an exception to (or a disclosure for purposes of) such other representations and warranties (or covenants, as applicable) is reasonably apparent on the face of such disclosure.

9.13 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart.
