NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound hereby, Parent, Merger Sub and the Company hereby agree as follows:

ARTICLE I

The Merger

SECTION 1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), at the Effective Time Merger Sub shall be merged with and into the Company, and the separate corporate existence of Merger Sub shall thereupon cease, and the Company shall be the surviving corporation in the Merger (the “Surviving Corporation”).

SECTION 1.2 Closing. The closing of the Merger (the “Closing”) shall take place at the offices of Weil, Gotshal & ▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇

▇▇▇▇ ▇▇▇▇▇ at 10:00 a.m. (New York City time) on a date to be specified by the parties, following the satisfaction or waiver (to the extent permitted by applicable Law) of the conditions set forth in Article VI (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions at such time), that is the earlier of (a) any business day before or during the Marketing Period as may be specified by Parent on no less than three business days’ prior notice to the Company and (b) the final day of the Marketing Period, or such other date, time, or place as agreed to in writing by the parties hereto. The date on which the Closing actually occurs is referred to in this Agreement as the “Closing Date”.

SECTION 1.3 Effective Time. Subject to the provisions of this Agreement, as soon as practicable on the Closing Date the parties shall file with the Secretary of State of the State of Delaware a certificate of merger, executed in accordance with, and in such form as is required by, the relevant provisions of the DGCL (the “Certificate of Merger”). The Merger shall become effective upon the filing of the Certificate of Merger or at such later time as is agreed to by the parties hereto and specified in the Certificate of Merger (the time at which the Merger becomes effective is herein referred to as the “Effective Time”).

SECTION 1.4 Effects of the Merger. The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

SECTION 1.5 Certificate of Incorporation and By-laws of the Surviving Corporation. At the Effective Time, the certificate of incorporation and by-laws of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated as of the Effective Time to be in the form of (except with respect to the name of the Company) the certificate of incorporation and by-laws of Merger Sub, and as amended shall be the certificate of incorporation and by-laws of Surviving Corporation until thereafter amended as provided therein or by applicable Law (and subject to Section 5.9 hereof).

SECTION 1.6 Directors and Officers of the Surviving Corporation.

(a) Each of the parties hereto shall take all necessary action to cause the directors of Merger Sub immediately prior to the Effective Time to be the directors of the Surviving Corporation immediately following the Effective Time, until their respective successors are duly elected or appointed and qualified or their earlier death, resignation or removal in accordance with the certificate of incorporation and by-laws of the Surviving Corporation.

(b) The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation until their respective successors

are duly appointed and qualified or their earlier death, resignation or removal in accordance with the certificate of incorporation and by-laws of the Surviving Corporation.

ARTICLE II

Effect of the Merger on the Capital Stock of the Constituent Corporations; Exchange of Certificates; Company Stock Options

SECTION 2.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of common stock, par value $.01 per share, of the Company (“Company Common Stock”) or any shares of capital stock of Merger Sub:

(a) Capital Stock of Merger Sub. Each issued and outstanding share of capital stock of Merger Sub shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $.01 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. Any shares of Company Common Stock that are owned by the Company as treasury stock, and any shares of Company Common Stock owned by Parent or Merger Sub, shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange therefor.

(c) Conversion of Company Common Stock. Each issued and outstanding share of Company Common Stock (other than shares to be canceled in accordance with Section 2.1(b) and Dissenting Shares) shall thereupon be converted automatically into and shall thereafter represent the right to receive an amount in cash equal to $17.50, without interest (the “Merger Consideration”). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate, which immediately prior to the Effective Time represented any such shares of Company Common Stock (each, a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration to be paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.2(b), without interest.

SECTION 2.2 Exchange of Certificates.

(a) Paying Agent. Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent for the holders of shares of Company Common Stock in connection with the Merger (the “Paying Agent”) to receive, on terms reasonably acceptable to the Company, for the benefit of holders of shares of Company Common Stock, the aggregate Merger Consideration to which holders of shares of Company Common Stock shall become

entitled pursuant to Section 2.1(c). Parent shall deposit such aggregate Merger Consideration with the Paying Agent at or prior to the Effective Time. Such aggregate Merger Consideration deposited with the Paying Agent shall, pending its disbursement to such holders, be invested by the Paying Agent as directed by Parent in (i) short-term direct obligations of the United States of America, (ii) short-term obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, (iii) short-term commercial paper rated the highest quality by either ▇▇▇▇▇’▇ Investors Service, Inc. or Standard and Poor’s Ratings Services or (iv) money market funds investing solely in a combination of the foregoing. Parent shall promptly replace any funds deposited with the Paying Agent lost through any investment made pursuant to this paragraph.

(b) Payment Procedures. Promptly after the Effective Time (but in no event more than two business days thereafter), the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of Company Common Stock (i) a letter of transmittal (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 Paying Agent, and which shall be in such form and shall have such other customary provisions as Parent and the Company may reasonably agree) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions (and such other customary documents as may reasonably be required by the Paying Agent), the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration, without interest, for each share of Company Common Stock formerly represented by such Certificate, and the Certificate so surrendered shall forthwith be canceled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition of payment that (x) the Certificate so surrendered shall be properly endorsed or shall otherwise be in proper form for transfer and (y) the Person requesting such payment shall have paid any transfer and other taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate surrendered and shall have established to the reasonable satisfaction of the Surviving Corporation that such tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration as contemplated by this Article II, without interest.

(c) Transfer Books; No Further Ownership Rights in Company Stock. The Merger Consideration paid in respect of shares of Company Common Stock upon the surrender for exchange of Certificates in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such Certificates, and at the Effective Time, the stock transfer books of the Company shall be closed and

thereafter there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. From and after the Effective Time, the holders of Certificates that evidenced ownership of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock, except as otherwise provided for herein or by applicable Law. Subject to the last sentence of Section 2.2(e), if, at any time after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.

(d) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will pay, in exchange for such lost, stolen or destroyed Certificate, the applicable Merger Consideration to be paid in respect of the shares of Company Common Stock formerly represented by such Certificate, as contemplated by this Article II.

(e) Termination of Fund. At any time following the first anniversary of the Closing Date, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) that had been made available to the Paying Agent and which have not been disbursed to holders of Certificates, and thereafter such holders shall be entitled to look only to Parent and the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the payment of any Merger Consideration that may be payable upon surrender of any Certificates held by such holders, as determined pursuant to this Agreement, without any interest thereon. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Authority shall become, to the extent permitted by applicable Law, the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(f) No Liability. Notwithstanding any provision of this Agreement to the contrary, none of the parties hereto, the Surviving Corporation or the Paying Agent shall be liable to any Person for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g) Withholding Taxes. Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to a holder of shares of Company Common Stock pursuant to this Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the “Code”), or under any provision of

state, local or foreign Tax Law. To the extent amounts are so withheld and paid over to the appropriate Government Authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. If any withholding obligation may be avoided by such holder providing information or documentation to Parent, the Surviving Corporation or the Paying Agent, such information shall be requested prior to any such withholding.

SECTION 2.3 Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by a stockholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (the “Dissenting Stockholders”), shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the “Dissenting Shares”), but instead such holder shall be entitled to receive such consideration as may be determined to be due to such Dissenting Stockholder pursuant to Section 262 of the DGCL (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the rights set forth in Section 262 of the DGCL), unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost rights to appraisal under the DGCL. If any Dissenting Stockholder shall have failed to perfect or shall have effectively withdrawn or lost such right, such holder’s shares of Company Common Stock shall thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the Merger Consideration for each such share of Company Common Stock, in accordance with Section 2.1, without any interest thereon. The Company shall give Parent (i) prompt notice of any written demands for appraisal of any shares of Company Common Stock, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to stockholders’ rights of appraisal, and (ii) the opportunity to control all negotiations and proceedings with respect to demands for appraisal under the DGCL.

SECTION 2.4 Company Stock Options and RSUs.

(a) At or prior to the Effective Time, the Company shall take all action necessary (including any necessary determinations and/or resolutions of the Board of Directors of the Company or a committee thereof) such that:

(i) Except as otherwise agreed by Parent and the holder thereof, each option outstanding immediately prior to the Effective Time (whether or not then vested or exercisable) that represents the right to acquire shares of Company Common Stock and was issued under a Company Stock Plan (each, an “Option”) shall at the Effective Time be cancelled and terminated and converted at the Effective Time into the

right to receive a cash amount equal to the Option Consideration for each share of Company Common Stock then subject to the Option. The Option Consideration shall be paid by the Surviving Corporation on the Closing Date. For purposes of this Agreement, “Option Consideration” means, with respect to any share of Company Common Stock issuable under a particular Option, an amount equal to the excess, if any, of (i) the Merger Consideration per share of Company Common Stock over (ii) the exercise price payable in respect of such share of Company Common Stock issuable under such Option.

(ii) Immediately prior to the Effective Time, except as otherwise agreed by Parent and the holder thereof, each restricted stock unit in respect of a share of Company Common Stock issued under a Company Stock Plan (collectively, the “RSUs”) which is subject only to time based vesting criteria shall vest in full and be converted into the right to receive the Merger Consideration in respect thereof, and the holder of such RSU shall be paid on the Closing Date, an aggregate amount of cash as the holder would have been entitled to receive had such RSU been vested in full and settled immediately before the Effective Time (the “RSU Consideration”).

(iii) The Surviving Corporation shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Section 2.4 to any holder of Options or RSUs such amount as the Surviving Corporation is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, or local Tax Law, and the Surviving Corporation shall make any required filings with and payments to Taxing authorities relating to any such deduction or withholding. To the extent that amounts are so deducted and withheld by the Surviving Corporation, such withheld amounts shall be treated for the purposes of this Agreement as having been paid to the holder of Options or RSUs in respect of which such deduction and withholding was made by the Surviving Corporation.

(b) The holders of RSUs that are subject to performance based vesting criteria have such rights as are conferred on them by the terms of their grants. Subject to such rights, the Company and Parent will work together in good faith to determine the appropriate treatment upon the Closing for such RSUs.

SECTION 2.5 Adjustments. Notwithstanding any provision of this Article II to the contrary, if between the date of this Agreement and the Effective Time the outstanding shares of Company Common Stock shall have been changed into a different number of shares or a different class by reason of the occurrence or record date of any stock dividend, subdivision, reclassification,

recapitalization, split, combination, exchange of shares or similar transaction, the Merger Consideration shall be appropriately adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or similar transaction.

ARTICLE III

Representations and Warranties of the Company

The Company represents and warrants to Parent and Merger Sub that except as disclosed (a) in the disclosure schedule delivered by the Company to Parent simultaneously with the execution of this Agreement (the “Company Disclosure Schedule”), or (b) other than in the case of the representations and warranties set forth in Sections 3.2(a) through (c), 3.16(a)(iii) and 3.18, in (or incorporated by reference in) the Company SEC Documents (as hereinafter defined) filed and publicly available prior to the date of this Agreement (the “Filed Company SEC Documents”) other than the Excluded Disclosures (it being understood that any matter disclosed in the Company Disclosure Schedule or in (or incorporated by reference in) such Company SEC Documents shall be deemed disclosed with respect to any section of this Article III to which the matter relates (except as specifically provided above) to the extent the relevance to each such section is readily apparent):

SECTION 3.1 Organization, Standing and Corporate Power.

(a) The Company is a corporation duly organized, validly existing and in good standing under the Laws of the State of Delaware and has all requisite corporate power and authority necessary to own or lease all of its properties and assets and to carry on its business as it is now being conducted. The Company is duly licensed or qualified to do business and is in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed, qualified or in good standing would not reasonably be expected to have a Material Adverse Effect (as defined below) on the Company. For purposes of this Agreement, “Material Adverse Effect” shall mean any change, event or occurrence which, individually or in the aggregate, does have or would reasonably be expected to have, a material adverse effect on the business, results of operations or financial condition of the Company and its Subsidiaries taken as a whole, other than changes, events, occurrences or effects (i) generally affecting (A) the industry in which the Company and its Subsidiaries operates, provided that such changes, events, occurrences or effects do not affect the Company and its Subsidiaries in a materially disproportionate manner as compared to other participants in such industry, or (B) the economy, credit or financial or capital markets, in the United States or elsewhere in the world, including changes in interest or exchange rates, or (ii) arising out of, resulting from or attributable to (A) changes in Law or in generally accepted accounting principles or in accounting standards, or changes in general legal, regulatory or political conditions, (B) the negotiation, execution, announcement or performance of this Agreement or the consummation of the Transactions, including the impact thereof on relationships, contractual or otherwise, with customers, suppliers, distributors, partners or employees, or any litigation arising from allegations of breach of fiduciary duty or

violation of Law relating to this Agreement or the Transactions, (C) acts of war, sabotage or terrorism, or any escalation or worsening of any such acts of war, sabotage or terrorism, (D) earthquakes, hurricanes, tornados or other natural disasters, (E) any action taken by the Company or its Subsidiaries that is required by this Agreement (including, without limitation, actions required under Section 2.4) or with Parent’s written consent or at Parent’s written request, (F) any decline in the market price, or change in trading volume, of the capital stock of the Company, or (G) any failure to meet any internal or public projections, forecasts or estimates of revenue or earnings in and of itself (for the avoidance of doubt, the exceptions in clauses (F) and (G) shall not prevent or otherwise affect a determination that the underlying cause of any such failure is a Material Adverse Effect).

(b) Each of the Company’s Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization except where the failure to be so organized, existing and in good standing does not have and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(c) The Company has made available to Parent complete and correct copies of the certificate of incorporation and by-laws of the Company, as amended to the date of this Agreement (the “Company Charter Documents”).

SECTION 4.4 Ownership and Operations of Merger Sub. Parent owns beneficially and of record all of the outstanding capital stock of Merger Sub. Merger Sub was formed solely for the purpose of engaging in the Transactions, has engaged in no other business activities and has conducted its operations only as contemplated hereby.

SECTION 4.5 Financing.

(a) Parent has delivered to the Company true, correct and complete copies, as of the date of this Agreement, of (i) executed commitment letters (the “Equity Funding Letters”) from Silver Lake Partners III, L.P. and TPG Partners V, L.P. (each, an “Equity Provider”, and collectively the “Equity Provider Group”) to provide, subject to the terms and conditions therein, equity financing in the aggregate amount set forth therein (being collectively referred to as the “Equity Financing”), and (ii) executed commitment letters and redacted forms of fee letters, dated as of the date of this Agreement, from ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Senior Funding, Inc., Citigroup Global Markets Inc., JPMorgan Securities Inc. and JPMorgan Chase Bank, N.A. (the “Debt Commitment Letters” and, together with the Equity Funding Letters, the “Financing 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”). As of the date hereof, none of the Equity Funding Letters or Debt Commitment Letters has been amended or modified, no such amendment or modification is contemplated, and the respective commitments contained in such letters have not been withdrawn or rescinded in any respect. Parent or Merger Sub has fully paid any and all commitment fees or other fees in connection with the Equity Funding Letters and the Debt Commitment Letters that are payable on or prior to the date hereof and, as of the date hereof, the Equity Funding Letters and the Debt Commitment Letters (or, if applicable, any alternative debt commitment letters entered into pursuant to Section 5.5(a)) are the valid, binding and enforceable obligations of Parent and Merger Sub, and to the Knowledge of Parent, the other parties thereto. Assuming the Financing is funded and assuming the accuracy of the representations and warranties set forth in Article 3 and performance by the Company of its obligations under Section 5.2, the net proceeds contemplated by the Equity Funding Letters and Debt Commitment Letters will, together with Company cash, in the aggregate be sufficient for Merger Sub and the Surviving Corporation to pay the aggregate Merger Consideration, Option

Consideration and RSU Consideration (and any other repayment or refinancing of debt contemplated by this Agreement or the Equity Funding Letters or the Debt Commitment Letters) and any other amounts required to be paid in connection with the consummation of the Transactions and to pay all related fees and expenses. 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 Parent or Merger Sub under the Equity Funding Letters or the Debt Commitment Letters; provided that Parent is not making any representation regarding the effect of the inaccuracy of the representations and warranties in Article 3. As of the date of this Agreement, Parent does not have 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 Parent or Merger Sub on the date of the Closing; provided that Parent is not making any representation regarding the inaccuracy of the representations and warranties set forth in Article 3, or the failure of the Company to perform its obligations hereunder. The Financing Letters contain all of the conditions precedent to the obligations of the parties thereunder to make Financing available to Parent on the terms therein.

Neither Parent, Merger Sub nor any member of the Equity Provider Group has caused or induced any Person to take any action that, if taken by Parent, Merger Sub or any member of the Equity Provider Group, would be a breach of, or would cause to be untrue, any of the representations in this Section 4.5(b).

SECTION 4.6 Guarantee. Concurrently with the execution of this Agreement, Parent has delivered to the Company duly executed limited guarantees of each of Silver Lake Partners III, L.P. and TPG Partners V, L.P. (collectively, the “Guarantors”) with respect to certain matters on the terms specified therein (the “Guarantee”). Each Guarantee is in full force and effect and is the valid, binding and enforceable obligation of the applicable Guarantor, and no event has occurred, which, with or without notice, lapse of time or both, would constitute a default on the part of such Guarantor under such Guarantee.

SECTION 4.7 Solvency. Neither Parent nor Merger Sub is entering into the Transactions with the intent to hinder, delay or defraud either present or future creditors. Immediately after giving effect to all of the Transactions, including the Financing, any alternative financing and the payment of the aggregate Merger Consideration, the Option

Consideration and the RSU Consideration under Section 2.4 and any other repayment or refinancing of debt that may be contemplated in the Commitment Letters, assuming (a) satisfaction of the conditions to Parent’s obligation to consummate the Merger as set forth herein, or the waiver of such conditions, and (b) the accuracy of the representations and warranties of the Company set forth in Article III hereof (for such purposes, such representations and warranties shall be true and correct in all material respects) and (c) any estimates, projections or forecasts of the Company and its Subsidiaries have been prepared in good faith based upon reasonable assumptions, and payment of all related fees and expenses, the Surviving Corporation will be Solvent. For purposes of this Section 4.7, the term “Solvent” with respect to the Surviving Corporation means that, as of any date of determination, (a) the amount of the fair saleable value of the assets of the Surviving Corporation and its Subsidiaries, taken as a whole, exceeds, as of such date, the sum of (i) the value of all liabilities of the Surviving Corporation and its Subsidiaries, taken as a whole, including contingent and other liabilities, as of such date, as such quoted terms are generally determined in accordance with the applicable federal Laws governing determinations of the solvency of debtors, and (ii) without duplication of liabilities in clause (i), the amount that will be required to pay the probable liabilities of the Surviving Corporation and its Subsidiaries, taken as a whole on its existing debts (including contingent liabilities) as such debts become absolute and matured; (b) the Surviving Corporation will not have, as of such date, an unreasonably small amount of capital for the operation of the business in which it is engaged or proposed to be engaged by Parent following such date; and (c) the Surviving Corporation will be able to pay its liabilities, including contingent and other liabilities, as they mature.

SECTION 4.9 Brokers and Other Advisors. No broker, investment banker, financial advisor or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the Transactions based upon arrangements made by or on behalf of Parent or any of its Subsidiaries except for Persons whose fees and expenses will be paid by Parent.

Notwithstanding anything to the contrary herein, (1) the Board of Directors of the Company may change, qualify, withdraw or modify, in any manner adverse to the Parent, the Company Board Recommendation if such Board determines in good faith for reasons not related to the receipt of a Takeover Proposal, after consultation with outside legal counsel, that the failure to take such action could reasonably be determined to be inconsistent with its fiduciary duties under applicable Law provided, however, that nothing in this clause (1) will relieve the Company of any of its obligations under the first sentence of Section 5.1(a), and/or (2) if the Board of Directors of the Company receives a Takeover Proposal that the Board of Directors of the Company determines in good faith, after consultation with independent financial advisors and outside legal counsel, constitutes a Superior Proposal, the Company may make a Company Adverse Recommendation Change or enter into a Company Acquisition Agreement with respect to such Superior Proposal if the Company concurrently terminates this Agreement pursuant to Section 7.1(d)(ii) provided however, that, except with respect to a Public Equity Superior Proposal (w) the Company has given Parent at least five (5) business days’ prior written notice of its intention to take such action (which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal) and has contemporaneously provided a copy of the relevant proposed transaction agreements with the party making such Superior Proposal and other material documents), (x) the Company has negotiated in good faith with Parent during such notice period to the extent Parent wishes to negotiate, to enable the Parent to propose changes to the terms of this Agreement, the Financing Letters and the Guarantees that would cause such Superior Proposal to no longer constitute a Superior Proposal, (y) the Board of Directors of the Company shall have considered in good faith any changes to this Agreement, the Financing Letters and the Guarantees proposed in writing by Parent and shall have determined that the Superior Proposal would continue to constitute a Superior Proposal if such changes were to be given effect, and (z) in the event of any material change to the material terms of such Superior Proposal, the Company shall, in each case, have delivered to Parent an additional notice and the notice period shall have recommenced; and provided, further that the Company has complied in all material respects with its obligations under this Section 5.3 and provided, further, that any

purported termination of this Agreement pursuant to this sentence shall be void and of no force or effect, unless the Company pays Parent the Termination Fee in accordance with Section 7.3 prior to or concurrently with such termination.

(f) Nothing in this Section 5.3 shall prohibit the Board of Directors of the Company from taking and disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act, or other applicable Law, if such Board determines, after consultation with outside legal counsel, that failure to so disclose such position could constitute a violation of applicable Law. In addition, it is understood and agreed that, for purposes of this Agreement (including Article VII), a factually accurate public statement by the Company that only describes the Company’s receipt of a Takeover Proposal and the operation of this Agreement with respect thereto, or any temporary “stop, look and listen” communication by the Board of Directors of the Company pursuant to Rule 14d.9(f) of the Exchange Act, or any similar temporary communication to the stockholders of the Company, shall not constitute a Company Adverse Recommendation Change or a withdrawal or modification, or proposal by the Board of Directors of the Company to withdraw or modify, such Board’s recommendation of this Agreement or the Transactions, or an approval or recommendation with respect to any Takeover Proposal.

(g) As used in this Agreement, “Takeover Proposal” shall mean any inquiry, proposal or offer from any Person (other than Parent and its Subsidiaries) relating to, in a single transaction or series of related transactions, any (A) acquisition of assets of the Company and its Subsidiaries (including securities of Subsidiaries, but excluding sales of assets in the ordinary course of business) equal to 20% or more of the Company’s consolidated assets or to which 20% or more of the Company’s revenues or earnings on a consolidated basis are attributable, (B) acquisition of 20% or more of the outstanding Company Common Stock, (C) tender offer or exchange offer that if consummated would result in any Person beneficially owning 20% or more of the outstanding Company Common Stock, (D) merger, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company or (E) any combination of the foregoing types of transactions if the sum of the percentage of consolidated assets, consolidated revenues or earnings and Company Common Stock involved is 20% or more; in each case, other than the Transactions.

(h) As used in this Agreement, “Superior Proposal” shall mean any bona fide written Takeover Proposal on terms which the Board of Directors of the Company determines in good faith, after consultation with the Company’s outside legal counsel and independent financial advisors, to be more favorable from a financial point of view to the holders of Company Common Stock than the Merger, taking into account all the terms and conditions of such proposal (including the likelihood and timing of consummation thereof), and this Agreement (including any changes to the terms of this Agreement proposed by Parent to the Company in writing in response to such proposal or otherwise), provided that for purposes of the definition of “Superior Proposal”, the

references to “20%” in the definition of Takeover Proposal shall be deemed to be references to “50%.”

SECTION 5.4 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each of the parties hereto shall cooperate with the other parties and use (and shall cause their respective Subsidiaries to use) their respective reasonable best efforts to promptly (i) take, or cause to be taken, all actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to Closing to be satisfied as promptly as practicable and to consummate and make effective, in the most expeditious manner practicable, the Transactions, including preparing and filing promptly and fully all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents (including any required or recommended filings under applicable Antitrust Laws), and (ii) obtain all approvals, consents, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the Transactions. For purposes hereof, “Antitrust Laws” means the ▇▇▇▇▇▇▇ Act, as amended, the ▇▇▇▇▇▇▇ Act, as amended, the HSR Act, the Federal Trade Commission Act, as amended, all applicable Foreign Antitrust Laws and all other applicable Laws issued by a Governmental Authority that are designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade or lessening of competition through merger or acquisition.

(b) In furtherance and not in limitation of the foregoing, (i) each party hereto agrees to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the Transactions as promptly as practicable and in any event within ten business days of the date hereof and to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act and use its reasonable best efforts to take, or cause to be taken, all other actions consistent with this Section 5.4 necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act (including any extensions thereof) as soon as practicable; (ii) Parent agrees to file with the European Commission as promptly as reasonably practicable the Form CO, if any, required for the Transactions pursuant to the EC Merger Regulation and the Company agrees to provide Parent as promptly as practicable with such assistance as Parent reasonably requests for the purposes of filing such Form CO and, if such a filing is made, each party agrees to supply as promptly as practical any additional information and documentary material that may be required or requested by the European Commission and use its reasonable best efforts to take or cause to be taken all other actions consistent with this Section 5.4 necessary to obtain a decision from the European Commission declaring the Transactions compatible with the Common Market; and (iii) the Company and Parent shall each use its reasonable best efforts to (x) take all action necessary to ensure that no state takeover statute or similar Law is or becomes applicable to any of the Transactions and (y) if any state takeover statute or similar Law becomes applicable to any of the Transactions, take all action necessary to ensure that the Transactions may be

consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise minimize the effect of such Law on the Transactions.

(c) Each of the parties hereto shall use its reasonable best efforts to (i) cooperate in all respects with each other in connection with any filing or submission with a Governmental Authority in connection with the Transactions and in connection with any investigation or other inquiry by or before a Governmental Authority relating to the Transactions, including any proceeding initiated by a private party, and (ii) keep the other party informed in all material respects and on a reasonably timely basis of any material communication received by such party from, or given by such party to, the Federal Trade Commission, the Antitrust Division of the Department of Justice, the European Commission or any other Governmental Authority and of any material communication received or given in connection with any proceeding by a private party, in each case regarding any of the Transactions. Subject to applicable Laws relating to the exchange of information, each of the parties hereto shall have the right to review in advance, and to the extent practicable each will consult the other on, all the information relating to the other parties and their respective Subsidiaries, as the case may be, that appears in any filing made with, or written materials submitted to, any third party and/or any Governmental Authority in connection with the Transactions, other than “4(c) documents” as that term is used in the rules and regulations under the HSR Act.

(d) In furtherance and not in limitation of the covenants of the parties contained in this Section 5.4, each of the parties hereto shall use its reasonable best efforts to resolve such objections, if any, as may be asserted by a Governmental Authority with respect to the application of Antitrust Laws to the Transactions. Without limiting any other provision hereof, Parent and the Company shall each use its reasonable best efforts to (i) avoid the entry of, or to have vacated or terminated, any decree, decision, order or judgment that would restrain, prevent or delay the consummation of the Transactions, on or before the Walk-Away Date, including by defending through litigation on the merits any claim asserted in any court by any Person, and (ii) avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority with respect to the Transactions so as to enable the consummation of the Transactions to occur as soon as reasonably possible (and in any event no later than the Walk-Away Date). Notwithstanding anything to the contrary, Parent shall use its reasonable best efforts to take all such actions, including (y) proposing, negotiating, committing to and effecting, by consent decree, hold separate order, or otherwise, the sale, divestiture or disposition of such assets or businesses of Parent (or any of its subsidiaries) and (z) otherwise taking or committing to take actions that limit Parent or its subsidiaries’ freedom of action with respect to, or its ability to retain, one or more of its or its subsidiaries’ businesses, product lines or assets, in each case, as may be required in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order, or other decision or order in any suit or proceeding under Antitrust Laws, which would otherwise have the effect of preventing or materially delaying the consummation of the Transactions; provided, however, that Parent shall not be required to take any such actions which

would reasonably be expected to have a Material Adverse Effect. The Company shall take such of the foregoing actions as Parent may request; provided that any such action is conditioned upon the consummation of the Merger.

SECTION 5.5 Financing.

(a) Subject to the terms and conditions of this Agreement, each of Parent and Merger Sub shall use its reasonable best efforts to obtain the Financing on the terms and conditions described in the Financing Letters (or terms no less favorable to Parent or the Company (including with respect to the conditionality thereof)) and shall not permit any amendment or modification to be made to, or any waiver of any material provision or remedy under the Financing Letters, if such amendment, modification, waiver or remedy reduces the aggregate amount of the Financing or amends the conditions precedent to the Financing in a manner that would reasonably be expected to delay or prevent the Closing Date or make the funding of the Financing less likely to occur; provided that Parent and Merger Sub may replace and amend the Debt Commitment Letters so long as (i) the aggregate amount of the debt financing contemplated thereby is not decreased by an amount that exceeds the amount, if any, by which the aggregate amount of the equity financing contemplated by the Equity Financing Letters is increased, (ii) the terms are no less favorable to Parent or the Company, including with respect to conditionality thereof, and (iii) would not expand the conditions to the debt financing set forth in the Debt Commitment Letters as of the date hereof in a manner that would reasonably be expected to delay or prevent the Closing; and in any such event Parent 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 Debt Commitment Letters providing for such alternative financing and, if requested to do so, the Company shall within a reasonable time (and in no event more than 3 business days thereafter) inform Parent as to whether it agrees that such alternative financing is on terms no less favorable (including, with respect to the conditionality thereof) to the Company than the Financing Letters. For purposes of this Section 5.5, references to “Financing” shall include the financing contemplated by the Financing Letters as permitted to be amended, modified or replaced by this Section 5.5(a) and references to “Debt Commitment Letters” shall include such documents as permitted to be amended, modified or replaced by this Section 5.5(a). Each of Parent and Merger Sub shall use its reasonable best efforts (i) to maintain in effect the Financing Letters and to negotiate definitive agreements with respect to the Debt Commitment Letters on the terms and conditions (including the flex provisions) contained in the Debt Commitment Letters (or on terms no less favorable to Parent or Merger Sub than the terms and conditions (including flex provisions) in the Debt Commitment Letters), (ii) to satisfy all conditions applicable to it and within its control in such definitive agreements and consummate the Financing at or prior to the Closing, and (iii) to comply with its obligations under the Financing Letters. Parent shall keep the Company informed on a reasonably current basis and in reasonable detail of the status of its efforts to arrange the Financing and provide to the Company copies of all documents related to the Financing

(other than any ancillary documents subject to confidentiality agreements, including fee letters and engagement letters). In the event that all conditions in the Financing Letters (other than in connection with the Debt Financing, the availability of funding of any of the Equity Financing) have been satisfied or, upon funding will be satisfied, and taking into account the obligations of Parent and Merger Sub with respect to bridge financing, Parent and Merger Sub shall use their reasonable best 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 Merger and the other Transactions. In the event that (i) all conditions in Sections 6.1 and 6.2 have been satisfied (or, with respect to certificates to be delivered at the Closing, are capable of being satisfied upon the Closing) at the time when the Closing would have occurred but for the failure of the Equity Financing to be funded, (ii) the financing provided for by the Debt Commitment Letters (or, if alternative financing is being used in accordance with this Section 5.5, pursuant to the commitments with respect thereto) has been funded or will be funded at the Closing if the Equity Financing is funded at the Closing, and (iii) the Company has irrevocably confirmed that if the Equity Financing and the Debt Financing are funded such that the Closing pursuant to Article II could occur, the Company is willing to waive all conditions in Section 6.3, Parent shall enforce its rights under the Equity Funding Letters to cause the Equity Financing to be funded at the Closing. If any portion of the Debt Financing becomes unavailable on the terms and conditions (including the flex provisions) contemplated by the Debt Commitment Letters, (A) Parent and Merger Sub shall immediately notify the Company and (B) Parent and Merger Sub shall use their reasonable best efforts to arrange and obtain alternative financing from alternative sources in an amount sufficient to consummate the Transactions with terms and conditions not materially less favorable to Parent than the terms and conditions set forth in the Debt Commitment Letters (including the flex provisions) (as determined in the reasonable judgment of Parent) as promptly as practicable following the occurrence of such event but no later than the final day of the Marketing Period. Parent shall give the Company prompt notice of any material breach by any party to the Financing Letters or of any condition not likely to be satisfied, in each case, of which Parent or Merger Sub becomes aware or any termination of the Financing Letters. For the avoidance of doubt, in the event that (x) all or any portion of the Debt Financing structured as privately offered notes is not yet received by Parent or Merger Sub, (y) the conditions to closing in Article VI (other than the delivery of officers’ certificates contemplated in Sections 6.2(a), 6.2(b), 6.3(a) or 6.3(b)) shall have been satisfied or waived and (z) the bridge facilities contemplated by the Debt Commitment Letters (or alternative bridge financing obtained in accordance with this Agreement) are available in all material respects on the terms and conditions (including the flex provisions) described in the Debt Commitment Letters (or described in replacements thereof on terms and conditions no less favorable to Parent or Merger Sub or alternative financing thereof), then Parent shall cause the proceeds of such bridge financing (or replacement or alternative financing) to be used to replace such privately offered note financing no later than the final day of the Marketing Period. Parent and Merger Sub acknowledge and agree that the obtaining of the Financing, or any alternative financing, is not a condition to Closing. Notwithstanding anything contained

in this Section 5.5 or in any other provision of this Agreement, in no event shall Parent or Merger Sub be required (1) to amend or waive any of the terms or conditions hereof or (2) to consummate the Closing any earlier than the final day of the Marketing Period.

(b) Prior to the Closing Date, the Company shall provide to Parent and Merger Sub, and shall cause its Subsidiaries to provide, at Parent’s sole expense, and shall use reasonable best efforts to cause its Representatives, including legal and accounting, to provide, all cooperation reasonably requested by Parent and that is customary in connection with the arrangement of the Financing or any permitted replacement, amended, modified or alternative financing (collectively with the Financing, the “Available Financing”) and the other Transactions (provided that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries), including (i) furnishing Parent and Merger Sub and their Financing sources as promptly as practicable with financial and other pertinent information regarding the Company and its Subsidiaries as may be reasonably requested in writing by Parent, including all financial statements and financial and other data of the type required by Regulation S-X (other than Item 3-10 of Regulation S-X) and Regulation S-K under the Securities Act for registered offerings of debt securities, and of the type and form customarily included in offering documents used in private placements under Rule 144A of the Securities Act, to consummate the offerings of debt securities contemplated by the Available Financing at the time during the Company’s fiscal year such offerings will be made (information required to be delivered pursuant to this clause (i) being referred to as, the “Required Information”), (ii) participating in a reasonable number of meetings, presentations, road shows, due diligence sessions, drafting sessions and sessions with rating agencies in connection with the Available Financing, (iii) assisting with the preparation of materials for rating agency presentations, offering documents, private placement memoranda, bank information memoranda, prospectuses and similar documents required in connection with the Available Financing; provided that any private placement memoranda or prospectuses in relation to debt securities need not be issued by the Company or any of its Subsidiaries, and provided, further, that any private placement memoranda or prospectuses shall contain disclosure and financial statements reflecting the Surviving Corporation and/or its Subsidiaries as the obligor, (iv) using reasonable best efforts to obtain accountant’s comfort letters, legal opinions, surveys and title insurance reasonably requested by Parent, (v) taking all corporate actions, subject to the occurrence of the Effective Time, reasonably requested by Parent to permit the consummation of the Available Financing and to permit the proceeds thereof to be made available to the Surviving Corporation immediately after the Effective Time, (vi) executing and delivering any pledge and security documents, other definitive financing documents or other certificates, or documents as may be requested by Parent (including a certificate of the chief financial officer of the Company or any of its Subsidiaries with respect to solvency matters and consents of accountants for use of their reports in any material relating to the Available Financing) and (vii) facilitating the consummation of the Available Financing and the direct borrowing or incurrence of all proceeds of the Available Financing, by the Surviving Corporation immediately following the Effective Time; provided, however,

that, no obligation of the Company or any of its Subsidiaries under any certificate, document or instrument (other than the representation letter referred to above) shall be effective until the Effective Time and, none of the Company or any of its Subsidiaries shall be required to pay any commitment or other similar fee or incur any other liability in connection with the Available Financing prior to the Effective Time. The Company hereby consents to the use of its and its Subsidiaries’ logos in connection with the Available Financing; provided that such logos are used solely in a manner that is not intended to or reasonably likely to harm or disparage the Company or any of its Subsidiaries or the reputation or goodwill of the Company or any of its Subsidiaries. Parent shall promptly, upon request by the Company, reimburse the Company for all reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) incurred by the Company or any of its Subsidiaries in connection with the cooperation of the Company and its Subsidiaries contemplated by this Section 5.5 and shall indemnify and hold harmless the Company, its Subsidiaries and their respective Representatives from and against any and all losses, damages, claims, costs or expenses suffered or incurred by any of them in connection with the arrangement of the Financing and any information used in connection therewith, except with respect to any information provided by the Company or any of its Subsidiaries.

(c) In no event shall Parent, Merger Sub or any member of the Equity Provider Group (i) retain any financial advisor on an exclusive basis other than (x) advisors to which the Board of Directors of the Company or the Company consents (which consent shall not be unreasonably withheld, delayed or conditioned) or (y) Affiliates of any member of the Equity Provider Group or (ii) enter into any agreement, arrangement or understanding, with any bank or investment bank or other potential provider of debt or equity financing on an exclusive basis (or otherwise on terms that could reasonably be expected to prevent such provider from providing or seeking to provide such financing to any third party in connection with a transaction relating to the Company or its Subsidiaries), in connection with the Merger or the Transactions. Notwithstanding the foregoing in clause (ii) of this Section 5.5(c), but subject to the other terms of this Agreement, including Section 5.4, Parent may seek and obtain equity commitments and equity financing with respect to the Parent Equity Share from (A) the partners of Silver Lake Partners III, L.P. and TPG Partners V, L.P. (“Parent Limited Partners”), the parties set forth in Section 5.5 of the Company Disclosure Schedule and their affiliates and other Persons consented to by the Company and (B) after the No-Shop Period Start Date, other Persons; provided that, (1) such other Persons are not, and their respective Affiliates are not, and do not subsequently become, lenders under the Debt Commitment Letters (or any alternative debt financing) on an exclusive basis and are not Excluded Parties that the Company has identified to Parent, and (2) doing so does not (y) expand in any respect upon the conditions precedent and other contingencies to the Financing set forth in the Financing Letters as of the date hereof or (z) prevent, impair or delay in any respect the availability of the Financing under the Financing Letters or the consumption of the Merger and other Transactions. For purposes of this Agreement, “Parent Equity Share” means the amount of equity financing committed to be provided by the Equity Providers pursuant to the Equity

Funding Letters. Neither Parent, Merger Sub nor any member of the Equity Provider Group shall cause or induce any Person to take any action that, if taken by Parent, Merger Sub or any member of the Equity Provider Group, would be a breach of, or would otherwise not be permitted by, this Section 5.5(c).

SECTION 5.6 Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by Parent and the Company. Except with respect to any Company Adverse Recommendation Change or any action taken pursuant thereto, and in accordance with Section 5.3 and Article VII, so long as this Agreement is in effect, neither the Company nor Parent shall issue or cause the publication of any press release or other public announcement (to the extent not previously issued or made in accordance with this Agreement) with respect to the Merger, this Agreement or the other Transactions without the prior consent of the other party (which consent shall not be unreasonably withheld or delayed), except as may be required by Law, applicable fiduciary duties or by any applicable listing agreement with a national securities exchange as determined in the good faith judgment of the party proposing to make such release (in which case such party shall not issue or cause the publication of such press release or other public announcement without prior consultation with the other party).

SECTION 5.7 Access to Information; Confidentiality. Subject to applicable Laws relating to the exchange of information, the Company shall afford to Parent and Parent’s representatives reasonable access during normal business hours to the Company’s officers, employees, agents, properties, books, Contracts and records and the Company shall furnish promptly to Parent such information concerning its business, personnel, assets, liabilities and properties as Parent may reasonably request (other than any publicly available document filed by it pursuant to the requirements of Federal or state securities Laws); provided that Parent and its representatives shall conduct any such activities in such a manner as not to interfere unreasonably with the business or operations of the Company; provided, however, that the Company shall not be obligated to provide such access or information if the Company determines, in its reasonable judgment, that doing so would violate applicable Law or a Contract or obligation of confidentiality owing to a third-party, waive the protection of an attorney-client privilege, or expose the Company to risk of liability for disclosure of sensitive or personal information. Without limiting the foregoing, in the event that the Company does not provide access or information in reliance on the preceding sentence, it shall use its reasonable best efforts to communicate, to the extent feasible, the applicable information in a way that would not violate the applicable Law, Contract or obligation or risk waiver of such privilege. Without limiting the generality of this Section 5.7, from the date of this Agreement until the Effective Time, the Company will furnish to the Parent promptly after becoming available, monthly financial statements including an unaudited balance sheet, income statement and statement of cash flows for each month through the Closing Date, as well as any update of its outlook for the quarter or the balance of the fiscal year, as it may prepare for management’s internal use. Until the Effective Time, the information provided will be subject to the terms of the letter agreement, dated as of May 7, 2007,

between Parent and Silver Lake Management Company, L.L.C. and TPG Capital, L.P. (as it may be amended from time to time, the “Confidentiality Agreement”), and, without limiting the generality of the foregoing, Parent shall not, and shall cause its representatives not to, use such information for any purpose unrelated to the consummation of the Transactions.

SECTION 5.8 Notification of Certain Matters. The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (i) any notice or other communication received by such party from any Governmental Authority in connection with the Transactions or from any Person alleging that the consent of such Person is or may be required in connection with the Transactions, if the subject matter of such communication or the failure of such party to obtain such consent could be material to the Company, the Surviving Corporation or Parent and (ii) any actions, suits, claims, investigations or proceedings commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries which relate to the Transactions.

SECTION 5.9 Indemnification and Insurance.

(a) From and after the Effective Time, Parent shall, and shall cause the Company and the Surviving Corporation to, (i) indemnify and hold harmless each individual who at the Effective Time is, or at any time prior to the Effective Time was, a director or officer of the Company or of a Subsidiary of the Company (each, an “Indemnitee” and, collectively, the “Indemnitees”) with respect to all claims, liabilities, losses, damages, judgments, fines, penalties, costs (including amounts paid in settlement or compromise) and expenses (including fees and expenses of legal counsel) in connection with any claim, suit, action, proceeding or investigation (whether civil, criminal, administrative or investigative), whenever asserted, based on or arising out of, in whole or in part, (A) the fact that an Indemnitee was a director or officer of the Company or such Subsidiary or (B) acts or omissions by an Indemnitee in the Indemnitee’s capacity as a director, officer, employee or agent of the Company or such Subsidiary or taken at the request of the Company or such Subsidiary (including in connection with serving at the request of the Company or such Subsidiary as a director, officer, employee, agent, trustee or fiduciary of another Person (including any employee benefit plan)), in each case under (A) or (B), at, or at any time prior to, the Effective Time (including any claim, suit, action, proceeding or investigation relating in whole or in part to the Transactions), to the fullest extent permitted under applicable Law, and (ii) assume all obligations of the Company and such Subsidiaries to the Indemnitees in respect of indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time as provided in (x) the Company Charter Documents and the organizational documents of such Subsidiaries as currently in effect and (y) the indemnification agreements listed on Section 5.9 of the Company Disclosure Schedule, which shall survive the Transactions and continue in full force and effect in accordance with their respective terms. Without limiting the foregoing, Parent, from and after the Effective Time until six years from the Effective Time, shall cause, unless otherwise required by law, the certificate of incorporation and by-laws of the Surviving

Corporation to contain provisions no less favorable to the Indemnitees with respect to limitation of liabilities of directors and officers and indemnification than are set forth as of the date of this Agreement in the Company Charter Documents, which provisions shall not be amended, repealed or otherwise modified in a manner that would adversely affect the rights thereunder of the Indemnitees. In addition, from and after the Effective Time, Parent shall, and shall cause the Company and the Surviving Corporation to, pay any expenses (including fees and expenses of legal counsel) of any Indemnitee under this Section 5.9 (including in connection with enforcing the indemnity and other obligations referred to in this Section 5.9) as incurred to the fullest extent permitted under applicable Law, provided that the person to whom expenses are advanced provides an undertaking to repay such advances to the extent required by applicable Law.

(b) An Indemnitee shall have the right, but not the obligation, to assume and control the defense of any litigation, claim or proceeding relating to any acts or omissions covered under this Section 5.9 (each, a “Claim”) with counsel selected by the Indemnitee, which counsel shall be reasonably acceptable to Parent; provided, however, that Parent (i) shall be permitted to participate in the defense of such Claim at its own expense, (ii) shall not be liable for any settlement effected without Parent’s written consent and (iii) shall not be liable for the fees and expenses of more than one counsel in addition to any local counsel. Each of Parent, the Company, the Surviving Corporation and the Indemnitees shall cooperate in the defense of any Claim and shall provide access to properties and individuals as reasonably requested and furnish or cause to be furnished records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith. Nothing in this Section 5.9(b) shall relieve Parent of its indemnity and other obligations set forth in Section 5.9(a) except to the extent provided in clause (ii) above.

(c) For the six-year period commencing immediately after the Effective Time, Parent shall maintain in effect the Company’s current directors’ and officers’ liability insurance covering acts or omissions occurring at or prior to the Effective Time with respect to those persons who are currently (and any additional persons who prior to the Effective Time become) covered by the Company’s directors’ and officers’ liability insurance policy on terms and scope with respect to such coverage, and in amount, not less favorable to such individuals than those of such policy in effect on the date hereof (or Parent may substitute therefor policies, issued by reputable insurers, of at least the same coverage with respect to matters occurring prior to the Effective Time, including a “tail” policy); provided, however, that, if the aggregate annual premiums for such insurance shall exceed 300% of the current aggregate annual premium, then Parent shall provide or cause to be provided a policy for the applicable individuals with the best coverage as shall then be available at an annual premium of 300% of the current aggregate annual premium; provided that any such replacement or substitution of insurance policies shall not result in gaps in coverage and; provided further, however, that at no time shall such coverage be less

than the directors’ and officers’ liability insurance coverage then provided by Parent to its directors and officers.

(b) For all purposes (including purposes of vesting, eligibility to participate and level of benefits) under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Company Employee after the Effective Time (including the Company Plans) (the “New Plans”), each Company Employee shall be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent as such Company Employee was entitled, before the Effective Time, to credit for such service under any similar Company employee benefit plan in which such Company Employee participated or was eligible to participate immediately prior to the Effective Time, provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, (i) each Company Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is replacing comparable coverage under a Company Plan in which such Company Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Company Employee, Parent shall cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Company Employee and his or her covered dependents, to the extent such conditions were inapplicable or waived under the comparable Old Plans of the Company or its Subsidiaries in which such Company Employee participated immediately prior to the Effective Time. Parent shall cause any eligible expenses incurred by any Company Employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such Company Employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Company 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.

(c) From and after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries to honor all obligations under the Company Plans and compensation and severance arrangements and agreements in accordance with their terms as in effect immediately before the Effective Time, provided that, subject to the requirements of Section 5.12(a), nothing herein shall prohibit the Surviving

Corporation from amending or terminating any particular Company Plan to the extent permitted by its terms or applicable Law.

Notwithstanding the foregoing, it is explicitly agreed that the Company shall be entitled to seek specific performance of Parent’s obligation to cause the Equity Financing to be funded to fund the Merger in the event that (i) all conditions in Sections 6.1 and 6.2 have been satisfied (or, with respect to certificates to be delivered at the Closing, are capable of being satisfied upon the Closing) at the time when the Closing would have occurred but for the failure of the Equity Financing to be funded, (ii) the financing provided for by the Debt Commitment Letters (or, if alternative financing is being used in accordance with Section 5.5, pursuant to the commitments with respect thereto) has been funded or will be funded at the Closing if the Equity Financing is funded at the Closing, and (iii) the Company has irrevocably confirmed that if specific performance is granted and the Equity Financing and Debt Financing are funded, then the Closing pursuant to Article II will occur. For the avoidance of doubt, (1) under no circumstances will the Company be entitled to monetary damages in excess of the amount of the Parent Termination Fee and (2) while the Company may pursue both a grant of specific performance of the type provided by the preceding sentence and the

payment of the Parent Termination Fee under Section 7.1(b), under no circumstances shall the Company be permitted or entitled to receive both a grant of specific performance of the type contemplated by the preceding sentence and any money damages, including all or any portion of the Parent Termination Fee.
