ARTICLE I

THE MERGER; CERTAIN RELATED MATTERS

Section 1.1 The Merger.

(a) 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, whereupon the separate existence of Merger Sub shall cease and the Company shall continue as

the surviving company (the "Surviving Company") and an indirect, wholly-owned Subsidiary of Parent.

(b) The Merger shall have the effects set forth in the applicable provisions of the DGCL. Without limiting the generality of the foregoing and subject thereto, at the Effective Time, all the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Company and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Company, all as provided under the DGCL and other applicable Law.

Section 1.2 Closing. The closing of the Merger (the "Closing") shall take place at 10:00 a.m., local time, on the second Business Day after the satisfaction or, to the extent permitted by applicable Law, waiver of the conditions set forth in Article VII (other than those conditions that, by their nature or terms, can only be satisfied at Closing, but subject to the satisfaction or, to the extent permitted by applicable Law, waiver of such conditions), at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, Four Times Square, New York, New York, unless another time, date or place is agreed to in writing by the parties. The date on which the Closing actually occurs is hereinafter referred to as the "Closing Date."

Section 1.3 Effective Time. Immediately following the Closing on the Closing Date, the parties shall cause the Merger to be consummated by filing a certificate of merger relating to the Merger (the "Certificate of Merger") with the Secretary of State of the State of Delaware, in such form as required by, and executed and acknowledged in accordance with, the applicable provisions of the DGCL (the date and time of such filing, or if another date and time is agreed to by the parties and specified in such filing, such specified date and time, being the "Effective Time").

Section 1.4 Certificate of Incorporation. At the Effective Time, the certificate of incorporation of the Company shall be amended and restated in its entirety as set forth in Exhibit A attached hereto, and as so amended, shall be the certificate of incorporation of the Surviving Company until thereafter changed or amended as provided by the DGCL or therein.

Section 1.5 Bylaws. Subject to Section 6.8(c), at the Effective Time, the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall become the bylaws of the Surviving Company, until thereafter changed or amended as provided by the DGCL, the certificate of incorporation of the Surviving Company and such bylaws.

Section 1.6 Directors. The directors of Merger Sub immediately prior to the Effective Time, from and after the Effective Time, shall be the directors of the Surviving Company, until the earlier of their death, resignation or removal or until their respective successors are duly elected and qualified.

Section 1.7 Officers. The officers of the Company immediately prior to the Effective Time, from and after the Effective Time, shall be the officers of the Surviving Company, until the earlier of their death, resignation or removal or until their respective successors are duly appointed and qualified.

ARTICLE II

CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

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 Company, Parent, Merger Sub or any holder of any shares of common stock, $0.01 par value per share, of the Company (the "Company Common Stock"):

(a) All shares of Company Common Stock that are held by the Company as treasury stock or that are owned by the Company (other than shares of Company Common Stock held either in a fiduciary or agency capacity that are beneficially owned by third parties), Parent, Merger Sub or any wholly-owned Subsidiary of the Company or Parent immediately prior to the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, shall cease to be outstanding and shall be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(b) Subject to Section 2.1(a), Section 2.2 and Section 2.3, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Company Restricted Shares, which shall be governed by Section 2.5(b)) shall be converted into and shall thereafter represent the right to receive an amount in cash equal to $55.00, without interest (the "Merger Consideration"). As of the Effective Time, all such shares of Company Common Stock shall cease to be outstanding, shall be automatically cancelled and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock (a "Certificate") or shares of Company Common Stock held in book-entry form ("Book-Entry Shares") shall cease to have any rights with respect thereto, except the right to receive, in accordance with this Section 2.1(b), the Merger Consideration upon surrender of such Certificate or of such Book-Entry Shares, without interest.

(c) Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time, without any action on the part of the holder thereof, shall be converted into and become one share of common stock of the Surviving Company, with the same rights, powers and privileges as the shares so converted, and shall constitute the only outstanding shares of capital stock of the Surviving Company.

Section 2.2 Certain Adjustments. Notwithstanding anything in this Agreement to the contrary, if, from the date of this Agreement until the Effective Time, the outstanding shares of Parent Common Stock or Company Common Stock shall have been changed into a different number of shares or a different class by reason of any reclassification, stock split (including a reverse stock split), recapitalization, split-up, combination, exchange of shares, readjustment or other similar transaction, or a stock dividend or stock distribution thereon shall be declared with a record date within said period, the Merger Consideration and any other similarly dependent items, including the Stock Option Exchange Ratio, as the case may be, shall be equitably adjusted to provide the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.

Section 2.3 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, shares ("Appraisal Shares") of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand and properly demands appraisal of such Appraisal Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL ("Section 262") shall not be converted into the right to receive the Merger Consideration as provided in Section 2.1(b), but rather the holders of Appraisal Shares shall be entitled to payment by the Surviving Company of the "fair value" of such Appraisal Shares in accordance with Section 262; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then the right of such holder to be paid the fair value of such holder's Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, the Merger Consideration as provided in Section 2.1(b), without interest. The Company shall give prompt notice to Parent of any demands received by the Company for appraisal of any shares of Company Common Stock, and Parent shall have the right to direct all negotiations and Proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent (which consent shall not be unreasonably withheld, delayed or conditioned), make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

Section 2.4 Exchange of Company Common Stock.

(a) Exchange Agent. At or prior to the Effective Time, Parent shall deposit with a nationally recognized financial institution selected by Parent with the Company's prior approval (which approval shall not be unreasonably withheld, delayed or conditioned) (the "Exchange Agent"), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article II, through the Exchange Agent, all of the cash sufficient to pay the aggregate Merger Consideration (the "Exchange Fund"). Parent shall cause the Exchange Agent to deliver the cash contemplated to be paid pursuant to Section 2.1 out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. Parent shall or shall cause the Surviving Company to promptly replace or restore the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Exchange Agent to make such payments under Section 2.1(b). Nothing contained in this Section 2.4(a) and no investment losses resulting from investment of the funds deposited with the Exchange Agent shall diminish the rights of any holder of Company Common Stock to receive the Merger Consideration.

(b) Exchange Procedures.

(i) Certificates. Parent shall instruct the Exchange Agent to mail (or in the case of The Depository Trust Company on behalf of "street" holders, deliver), as soon as reasonably practicable after the Effective Time, to each holder of record of a Certificate whose shares of Company Common Stock were converted into the right to receive the Merger Consideration pursuant to Section 2.1(b), (A) 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 Exchange Agent, and shall be in customary form

and have such other provisions as are reasonably satisfactory to both of the Company and Parent) and (B) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor, and Parent shall cause the Exchange Agent to pay and deliver in exchange thereof as promptly as practicable, the cash amount equal to (x) the number of shares of Company Common Stock represented by such Certificate multiplied by (y) the Merger Consideration, and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a Person other than the registered holder of such Certificate or establish to the satisfaction of Parent that such tax has been paid or is not applicable. Subject to Section 2.3, until surrendered as contemplated by this Section 2.4, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration. No interest shall be paid or accrue on any cash payable upon surrender of any Certificate.

(ii) Book-Entry Shares. Notwithstanding anything to the contrary contained in this Agreement, any holder of Book-Entry Shares shall not be required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent to receive the Merger Consideration that such holder is entitled to receive pursuant to this Article II. In lieu thereof, each holder of record of one or more Book-Entry Shares whose shares of Company Common Stock were converted into the right to receive the Merger Consideration pursuant to Section 2.1(b) shall, upon receipt by the Exchange Agent of an "agent's message" (or such other evidence, if any, of surrender as the Exchange Agent may reasonably request) be entitled to receive in exchange therefor, and Parent shall cause the Exchange Agent to pay and deliver as promptly as practicable the cash amount equal to (x) the number of shares of Company Common Stock represented by such Book-Entry Shares multiplied by (y) the Merger Consideration. No interest shall be paid or accrue on any cash payable upon surrender of any Book-Entry Shares.

(c) No Further Ownership Rights in Company Common Stock; Closing of Transfer Books. The Merger Consideration paid in accordance with the terms of this Article II upon the surrender of the Certificates or the Book-Entry Shares shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock (other than the right to receive the payments contemplated by this Article II). After the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Company of shares of Company Common Stock that were outstanding immediately prior to the

Effective Time. If, after the Effective Time, any Certificates formerly representing shares of Company Common Stock are presented to the Surviving Company or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock twelve (12) months after the Effective Time shall be delivered to Parent, upon demand, and any holder of Company Common Stock who has not theretofore complied with this Article II shall thereafter look only to Parent (subject to Section 2.4(e)) for payment of its claim for the Merger Consideration.

(e) No Liability . None of Parent, Merger Sub, the Surviving Company, the Exchange Agent or any other Person shall be liable to any Person in respect of any cash from the Exchange Fund (including any amounts delivered to Parent in accordance with Section 2.4(d)) properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificates or Book-Entry Shares shall not have been surrendered immediately prior to the date that such unclaimed funds would otherwise become subject to any abandoned property, escheat or similar Law, any unclaimed funds payable with respect to such Certificates or Book-Entry Shares shall, to the extent permitted by applicable Law, become the property of the Surviving Company, and any former holder of Company Common Stock who has not theretofore complied with this Section 2.4 shall thereafter look only to the Surviving Company for payment of its claim for Merger Consideration, without any interest thereon.

(f) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, to the extent customarily required by Parent, 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 Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration that would be payable in respect thereof pursuant to this Agreement had such lost, stolen or destroyed Certificate been surrendered as provided in this Article II.

(g) Investment. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent; provided that no losses on any investment made pursuant to this Section 2.4(g) shall affect the Merger Consideration payable to holders of Company Common Stock entitled to receive such consideration and following any such losses, Parent shall promptly cause to be provided additional funds to the Exchange Agent for the benefit of holders of shares of Company Common Stock entitled to receive such consideration in the amount of any such losses or if for any reason such funds are unavailable for payment to the holders of shares of Company Common Stock.

(h) Withholdings. Notwithstanding any provision contained herein to the contrary, each of Parent, the Surviving Company and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article II such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the "Code") or under any

provision of state, local or foreign tax Law. Any amount properly deducted or withheld pursuant to this Section 2.4(h) shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made. Parent shall pay, or shall cause to be paid, all amounts so deducted or withheld to the appropriate Taxing Authority within the period required under applicable Law.

Section 2.5 Treatment of Stock Plans.

(a) Treatment of Options. Subject to Section 2.2, at the Effective Time, each outstanding option to purchase shares of Company Common Stock (a "Company Option") granted under the Company Stock Plans, whether or not exercisable and whether vested or unvested, by virtue of the Merger and without any action on the part of the Company or the holder thereof, shall be converted into a stock option to acquire a number of shares of Parent Common Stock (rounded down to the nearest whole share) equal to the product of (i) the total number of shares of Company Common Stock subject to the Company Option immediately prior to the Effective Time times (ii) the Stock Option Exchange Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to (x) the exercise price applicable to such Company Option immediately prior to the Effective Time divided by (y) the Stock Option Exchange Ratio (each, a "Converted Option"). The "Stock Option Exchange Ratio" shall mean the Merger Consideration divided by the volume-weighted average price of the Parent Common Stock on the NYSE during the trading day on the Business Day preceding the Closing Date (the "Parent Common Stock Price"). Each Converted Option shall be subject to the same terms and conditions as applicable to the corresponding Company Option immediately prior to the Effective Time (taking into account any accelerated vesting of such Company Options in accordance with the terms thereof). For the avoidance of doubt, the exercise price of, and number of shares subject to, each Converted Option shall be determined as necessary to comply with Section 409A of the Code.

(b) Company Restricted Shares. Subject to Section 2.2, at the Effective Time, each outstanding award of shares of restricted Company Common Stock (each share, a "Company Restricted Share") granted under the Company Stock Plans, by virtue of the Merger and without any action on the part of the Company or the holder thereof, shall be converted into an award with respect to a number of restricted shares of Parent Common Stock equal to the product of (i) the total number of Company Restricted Shares subject to the award immediately prior to the Effective Time times (ii) the Stock Option Exchange Ratio (each, a "Converted Restricted Share Award"). Each Converted Restricted Share Award shall be subject to the same terms and conditions as applicable to the corresponding award of Company Restricted Shares immediately prior to the Effective Time (taking into account any accelerated vesting of such Company Restricted Shares in accordance with the terms thereof). Any fractional share of Parent Common Stock resulting from an aggregation of all Company Restricted Shares of a holder granted under a particular award agreement shall be rounded down to the nearest whole share. In lieu of any such fractional share, the holder of such Company Restricted Shares shall be entitled to an amount in cash equal to the product of (1) the amount of the fractional share times (2) the Parent Common Stock Price.

(c) Company Actions. At or prior to the Effective Time, the Company, the Board of Directors of the Company or the compensation committee of the Board of Directors

of the Company, as applicable, shall adopt any resolutions and take any actions which are reasonably necessary to effectuate the provisions of this Section 2.5. The Company shall take all reasonable actions necessary to ensure that from and after the Effective Time neither Parent nor the Surviving Company shall be required to deliver shares of Company Common Stock or other capital stock of the Company to any Person pursuant to or in settlement of Company Options, Company Restricted Shares or otherwise.

(d) Parent Actions. Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon exercise of the Converted Options and Converted Restricted Share Awards. Within two (2) Business Days following the Closing Date, Parent shall file a registration statement on Form S-8 (or any successor or other appropriate form) with respect to the shares of Parent Common Stock subject to such Converted Options and Converted Restricted Share Awards and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as Parent is subject to the reporting requirements pursuant to Section 13 or 15(d) of the Exchange Act and such Converted Options and Converted Restricted Share Awards remain outstanding. As soon as reasonably practicable following the Effective Time, but in no event later than two (2) Business Days following the Closing Date, Parent shall deliver to each holder of an outstanding Company Option or award of Company Restricted Shares at the Effective Time written notice describing the effect of the Merger on such Company Options and Company Restricted Shares.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as (x) disclosed in the Company SEC Documents filed with or furnished to the Securities and Exchange Commission (the "SEC") on or after January 1, 2009 and prior to the date of this Agreement (but excluding any risk factors or forward-looking disclosures set forth under the heading "Risk Factors" or under the heading "Special Note Regarding Forward-looking Statements," and any other disclosures that are cautionary, predictive or forward-looking in nature, in any such Company SEC Documents) or (y) set forth in the disclosure letter delivered by the Company to Parent and Merger Sub immediately prior to the execution and delivery of this Agreement (the "Company Disclosure Letter") (it being agreed that disclosure of any item in any section or subsection of the Company Disclosure Letter shall be deemed disclosure with respect to any section of this Agreement or any other section or subsection of the Company Disclosure Letter to which the relevance of such disclosure is reasonably apparent and that the mere inclusion of an item in such Company Disclosure Letter as an exception to a representation or warranty shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has had, would have or would reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect), and whether or not any particular representation or warranty refers to or excepts therefrom any specific Section of the Company Disclosure Letter, the Company represents and warrants to Parent and Merger Sub as follows:

Section 3.1 Corporate Organization.

(a) Each of the Company and its Subsidiaries is a corporation or other entity duly organized, validly existing and, to the extent applicable, in good standing under the Laws of the jurisdiction of its organization and has the requisite corporate or other entity power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted. Each of the Company and its Subsidiaries is duly licensed, qualified or otherwise authorized to do business, and, to the extent applicable, is in good standing, in each jurisdiction where 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, individually or in the aggregate, a Company Material Adverse Effect. The copies of the Amended and Restated Certificate of Incorporation (the "Company Charter") and the Second Amended and Restated Bylaws (the "Company Bylaws") of the Company made available to Parent are true, complete and correct copies of such documents as in effect as of the date of this Agreement.

(b) Section 3.1(b) of the Company Disclosure Letter lists all of the Subsidiaries of the Company and, for each such Subsidiary, the state of formation or incorporation and each jurisdiction in which such Subsidiary is qualified or licensed to do business.

Affiliate, investment banker, financial advisor, attorney, accountant or other representative retained by it or any of its Subsidiaries (collectively, "Representatives") acting on its behalf to, directly or indirectly, (i) solicit, initiate or knowingly encourage (including by way of furnishing information), or knowingly facilitate any inquiries or the making of any proposal which constitutes, or may reasonably be expected to lead to, any Acquisition Proposal, (ii) engage in any negotiations or discussions regarding any Acquisition Proposal or otherwise cooperate with, knowingly encourage or knowingly facilitate any effort by any Person that has made an Acquisition Proposal, (iii) grant any waiver or release under, or fail to enforce, any standstill or similar agreement with respect to any class of equity securities of the Company or any of its Subsidiaries to which the Company of any of its Subsidiaries is a party or by which any of them is bound, (iv) make any Recommendation Withdrawal (as defined below) other than in accordance with Section 6.3(b) or (v) enter into any agreement in principle, letter of intent, term sheet, merger agreement, acquisition agreement, option agreement or other similar instrument relating to an Acquisition Proposal; provided, however, that if, prior to obtaining Company Stockholder Approval and following the receipt of an unsolicited bona fide Superior Proposal, or an unsolicited bona fide written Acquisition Proposal which is reasonably expected to lead to a Superior Proposal, the Board of Directors of the Company determines in good faith, after consultation with outside legal counsel, that there is a reasonable probability that the failure to take action with respect to such Acquisition Proposal would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, the Company and its Representatives may, in response to such Acquisition Proposal, and subject to compliance with Section 6.3(c), (A) furnish information with respect to the Company to the Person making such Acquisition Proposal and its Representatives and financing sources pursuant to a confidentiality agreement (a copy of which shall be provided to Parent for informational purposes only) that contains provisions not less favorable in the aggregate to the Company than those contained in the Confidentiality Agreement; provided that (1) such confidentiality agreement may not include any provision calling for an exclusive right to negotiate with the Company and (2) to the extent not previously furnished to Parent, the Company furnishes Parent with all such nonpublic information delivered to such Person prior to or substantially concurrently with its delivery to such Person and (B) engage in discussions or negotiations with such Person regarding such Acquisition Proposal. It is agreed that any violation of the restrictions on the Company set forth in this Section 6.3 by any Representative of the Company or any of its Subsidiaries shall be a breach of this Section 6.3 by the Company.

(b) Notwithstanding any other provision of this Agreement, including Section 6.1 and 6.2, but subject to compliance with this Section 6.3, prior to receipt of the Company Stockholder Approval, the Board of Directors of the Company or, if required to address any conflict of interest, any committee thereof, may, in response to any bona fide, unsolicited Acquisition Proposal, (i) withdraw (or modify or qualify in a manner adverse to Parent) the Company Board Recommendation or (ii) fail to include the Company Board Recommendation in the Proxy Statement (any action described in these clauses (i) or (ii) being referred to as a "Recommendation Withdrawal"), if (1) the Board of Directors of the Company concludes in good faith, after consultation with its outside financial advisors and outside legal counsel, that such Acquisition Proposal constitutes a Superior Proposal; (2) the Board of Directors of the Company concludes in good faith, after consultation with its outside legal counsel, that there is reasonable probability that the failure to make a Recommendation

Withdrawal would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law; (3) the Board of Directors of the Company making the Recommendation Withdrawal provides Parent five (5) Business Days prior written notice of its intention to take such action, which notice shall include the information with respect to such Superior Proposal that is specified in Section 6.3(c), as well as a copy of such Acquisition Proposal (it being agreed that neither the delivery of such notice by the Company nor any public announcement thereof that the Company determines it is required to make under applicable Law shall constitute a Recommendation Withdrawal unless and until the Company shall have failed at or prior to the end of the period referred to in clause (4) below (and, upon the occurrence of such failure, such notice and such public announcement shall constitute a Recommendation Withdrawal) to publicly announce that it (A) is recommending this Agreement and (B) has determined that such other Acquisition Proposal (taking into account in (A) any modifications or adjustments made to this Agreement to which Parent has agreed in writing and in (B) any modifications or adjustments made to such other Acquisition Proposal) is not a Superior Proposal and has publicly rejected such Acquisition Proposal); (4) during the four (4) Business Days following such written notice (or such shorter period as specified below), if requested by Parent, the Board of Directors of the Company effecting the Recommendation Withdrawal and its Representatives have negotiated with Parent regarding any revisions to the terms of this Agreement proposed by Parent in writing in response to such Superior Proposal and (5) the Board of Directors of the Company concludes in good faith, after consultation with its outside legal counsel and financial advisors (and taking into account any adjustment or modification of the terms of this Agreement to which Parent has agreed in writing), that the Acquisition Proposal continues to be a Superior Proposal and that there is reasonable probability that the failure to make a Recommendation Withdrawal would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law. Any change to the financial terms or other material terms of any Superior Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3; provided, however, that in the event that the Company seeks to make a Recommendation Withdrawal as provided above, the notice period and the period during which the Company and its Representatives are required, if requested by Parent, to negotiate with Parent regarding any revisions to the terms of this Agreement proposed in writing by Parent in response to such new Acquisition Proposal pursuant to clause (4) above shall expire on the later to occur of (x) three (3) Business Days after the Company provides written notice of such new Acquisition Proposal to Parent and (y) the end of the original four (4) Business Day period described in clause (4) above.

(c) In addition to the obligations of the Company set forth in Sections 6.3(a) and 6.3(b) the Company shall notify Parent in writing promptly, and in any event no later than 24 hours, after receipt by the Company or any of its Representatives of any Acquisition Proposal, any communication from or on behalf of a third party that such third party is considering making an Acquisition Proposal or any request for information relating to the Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries by any third party that may be considering making, or has made, an Acquisition Proposal. The Company shall advise Parent orally and in writing of the material terms and conditions of such Acquisition Proposal, communication or request, including the identity of the third party making such Acquisition Proposal, communication or request.

(d) Nothing in this Agreement shall prohibit or restrict the Board of Directors of the Company, based on events, developments or occurrences that arise after the date hereof (in each case other than involving or relating to an Acquisition Proposal), from effecting a Recommendation Withdrawal if the Board of Directors of the Company concludes in good faith, after consultation with its outside legal counsel, that there is reasonable probability that the failure to take such action would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, provided that (x) the Company shall (A) promptly notify Parent in writing of its intention to take such action, which notice includes a description in reasonable detail of the nature of such event, development or occurrence prompting the Recommendation Withdrawal (it being understood that such notice shall not be deemed to be or constitute a Recommendation Withdrawal) and (B) negotiate in good faith with Parent for three (3) Business Days following such notice regarding revisions to the terms of this Agreement proposed by Parent in writing in response to such event, development or occurrence, and (y) the Board of Directors of the Company shall not effect any Recommendation Withdrawal unless, after the three (3) Business Day period described in the foregoing clause (B), the Board of Directors of the Company concludes in good faith, after consultation with its outside legal counsel, that there is a reasonable probability that the failure to take such action would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law.

(e) Notwithstanding any Recommendation Withdrawal, except as required by Law, until termination of this Agreement in accordance with its terms (x) in no event may the Company (A) enter into any agreement in principle, letter of intent, term sheet, merger agreement, acquisition agreement, option agreement or other similar instrument relating to an Acquisition Proposal, (B) make, facilitate or provide information in connection with any SEC or other regulatory filings in connection with the transactions contemplated by any Acquisition Proposal or (C) seek any third-party consents in connection with the transactions contemplated by any Acquisition Proposal, and (y) the Company shall otherwise remain subject to all of its obligations under this Agreement.

(g) For purposes of this Agreement:

"Acquisition Proposal " means any proposal, offer or indication of interest from any Person (other than Parent or any of its Subsidiaries or Affiliates) relating to, or that could reasonably be expected to lead to, (i) any direct or indirect acquisition or purchase (including through reinsurance), in one transaction or a series of related transactions, of assets or liabilities (including equity securities of any Subsidiary of the Company) or businesses that constitute 15% or more of the assets or liabilities of the Company and its Subsidiaries, taken as a whole, or 15% or more of any class of equity securities of the Company, (ii) any tender offer or exchange offer that if consummated would result in any Person or group of Persons beneficially owning (which has the meaning under Section 13(d) of the Exchange Act) securities of the Company representing 15% or more of the aggregate voting power of all securities of the Company or (iii) any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, share exchange or similar transaction involving the Company or any of its Subsidiaries, in each case, pursuant to which any Person or the stockholders of any Person would own securities of the Company or of any resulting parent company of the Company representing 15% or more of the aggregate voting power of all securities of the Company or of any resulting parent company of the Company; and

"Superior Proposal" means a bona fide, unsolicited Acquisition Proposal (with all references to "15%" in the definition of Acquisition Proposal being deemed to be references to "50%") made that is on terms that the Board of Directors of the Company determines in good faith (after consulting with its financial advisor and outside legal counsel), and considering all relevant factors as the Board of Directors of the Company considers to be appropriate (including, but not limited to, the timing, ability to finance, financial and regulatory aspects and likelihood of consummation of such proposal, and any amendments to this Agreement proposed in writing by, and binding upon, Parent which is received prior to the Board of Directors of the Company's determination that a Superior Proposal exists), is more favorable from a financial point of view (taking into account the foregoing factors) to the stockholders of the Company than the Merger and the other transactions contemplated hereby, and which the Board of Directors of the Company determines is reasonably likely to be consummated and for which financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to be available by the Board of Directors of the Company.

Section 6.4 Access to Information. The Company shall, and shall cause each of its Subsidiaries to, afford the Representatives of Parent reasonable access during normal business hours to its and its Subsidiaries' properties, books, records, Contracts and personnel, and shall furnish, and shall cause to be furnished, as promptly as reasonably practicable to Parent consistent with its legal obligations and obligations pursuant to Contracts all other information concerning the Company and its Subsidiaries' business, properties and personnel as Parent may reasonably request, in each case as is reasonably necessary or appropriate to facilitate the Merger and the other transactions contemplated hereby; provided, however, that (i) the Company may restrict the foregoing access to the extent that any applicable Law or Governmental Entity requires it or its Subsidiaries to restrict access to any properties or information and (ii) Parent shall not have access to individual performance or evaluation records, medical histories or other information that in the reasonable opinion of the Company is sensitive or the disclosure of which

could reasonably be expected to subject it or any of its Subsidiaries to risk of liability or information that is subject to attorney-client privilege or other privilege; provided, further, that the Company may restrict the foregoing access to those Persons who have entered into or are bound by a confidentiality agreement with it and to the extent required by applicable Law or Contract to which the Company or its respective Subsidiaries is a party. All such access shall be subject to reasonable restrictions imposed from time to time with respect to the provision of privileged communications or any applicable confidentiality agreement with any Person. In conducting any inspection of any properties of the Company and its Subsidiaries, Parent and its Representatives shall not (i) interfere with the business conducted at such property or (ii) damage any property or any portion thereof. Prior to the Effective Time, Parent and its Representatives shall not have the right to conduct environmental sampling at any of the facilities or properties of the Company or any of its Subsidiaries.

The parties shall cooperate with the reasonable requests of each other in seeking to obtain as promptly as practicable any such Consents.

(b) Without limiting the foregoing, Parent and its Affiliates and the Company and its Affiliates shall take any and all actions necessary to avoid each and every impediment under any Health Care Law, Antitrust Law, insurance Law or other applicable Law that may be asserted by any Governmental Entity with respect to this Agreement, the Merger and the other transactions contemplated hereby so as to enable the Closing to occur as promptly as practicable, including, without limitation, any of the following actions requested by any Governmental Entity, or necessary or appropriate to (x) obtain all Consents and exemptions and secure the expiration or termination of any applicable waiting period under the HSR Act; (y) resolve any objections that may be asserted by any Governmental Entity with respect to the Merger and the other transactions contemplated hereby; and (z) prevent the entry of, and have vacated, lifted, reversed or overturned, any Order that would prevent, prohibit, restrict or delay the consummation of the Merger and the other transactions contemplated hereby:

(ii) agree to terminate any Contract or other business relationship of Parent or any of its Affiliates or the Company or any of its Affiliates as may be required to obtain any necessary clearance of any Governmental Entity or to obtain termination of any applicable waiting period under any Antitrust Laws or clearance under any Health Care Laws, insurance Laws or other applicable Laws; and

(iii) oppose fully and vigorously (x) any administrative or judicial action or proceeding that is initiated (or threatened to be initiated) challenging this Agreement, the Merger or the other transactions contemplated hereby and (y) any request for, the entry of, and seek to have vacated or terminated, any Order that could restrain, prevent or delay the consummation of the Merger and the other transactions contemplated hereby, including, in the case of either (x) or (y) by defending through litigation, any action asserted by any Person in any court or before any Governmental Entity, and vigorously pursuing all available avenues of administrative and judicial appeal.

Notwithstanding the foregoing, prior to the Company or any of its Subsidiaries voluntarily agreeing to or undertaking any action described in or contemplated by this Section 6.5(b) that would reasonably be expected to have a material impact on the business, activities or services of the Company or any of its Subsidiaries after the Closing, the Company shall obtain the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed. Nothing in this paragraph shall otherwise be deemed to affect or modify the obligations of the parties pursuant to this Section 6.5, including subsection (b) hereof.

(c) Neither the Company nor Parent shall, and each of them shall cause its Affiliates not to directly or indirectly, acquire, purchase, lease or license (or agree to acquire, purchase, lease or license), by merging with or into or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business or any

corporation, partnership, association or other business organization or division or part thereof, or any securities or collection of assets, if doing so would reasonably be expected to: (i) impose any material delay in the obtaining of, or materially increase the risk of not obtaining, any Consent, or exemption of any Governmental Entity necessary to consummate the Merger and the other transactions contemplated hereby or the expiration or termination of any applicable waiting period; (ii) materially increase the risk of any Governmental Entity entering an Order prohibiting the consummation of the Merger and the other transactions contemplated hereby; (iii) materially increase the risk of not being able to remove any such Order on appeal or otherwise; or (iv) prevent or materially delay the consummation of the Merger and the other transactions contemplated hereby.

(d) In furtherance of the foregoing, the parties shall as promptly as practicable following the date of this Agreement make all Filings with all Governmental Entities that may be or may become reasonably necessary, proper or advisable under this Agreement and applicable Law to consummate and make effective the Merger and the other transactions contemplated hereby, including: (i) filing, or causing to be filed, no later than fifteen (15) Business Days after the date of this Agreement, (A) "Form A Statements" or similar change of control applications with the insurance commissioners (or other applicable regulators) in each jurisdiction where required by applicable insurance Law seeking approval of Parent's acquisition of control of each of the Company Regulated Subsidiaries which results from the Merger; (ii) Parent filing, or causing to be filed no later than fifteen (15) Business Days after the date of this Agreement, any pre-acquisition notifications on "Form E" or similar market share notifications to be filed in each jurisdiction where required by applicable insurance Law with respect to the Merger and the other transactions contemplated hereby; (iii) not later than ten (10) Business Days following the date of this Agreement, the Company and Parent each making an appropriate filing of a notification and report form pursuant to the HSR Act with the Federal Trade Commission ("FTC") and the Antitrust Division of the United States Department of Justice ("DOJ") with respect to the Merger and the other transactions contemplated hereby and requesting early termination of the initial waiting period under the HSR Act; (iv) the Company and Parent each making any other filing that may be required under any other Antitrust Laws or by any Antitrust Authority; (v) not later than sixty (60) days prior to the Closing, the Company and Parent filing any required notices to CMS, with a separate notice to the CMS Medicare Drug Benefit Group and Central Office Medicare Advantage plan manager if applicable; and (vi) the Company and Parent making any other filing that may be required under any Health Care Laws or insurance or other applicable Law or by any Governmental Entity with jurisdiction over enforcement of any such Law.

(e) The Company and Parent shall, as promptly as practicable, (i) furnish each other and, upon request, any Governmental Entity, any information or documentation concerning themselves, their Affiliates, directors, officers, securityholders and Financing Sources, information or documentation concerning the Merger and the other transactions contemplated hereby and such other matters as may be requested and (ii) make available their respective personnel and advisers to each other and, upon request, any Governmental Entity, in connection with (A) the preparation of any statement, filing, notice or application made by or on their behalf to any Governmental Entity in connection with the Merger or the other transactions contemplated hereby or (B) any review or approval process.

(f) Subject to applicable Law relating to the sharing of information, each of the Company and Parent shall promptly notify the other of any Filing, communication or inquiry it or any of its Affiliates intends to make with or receives from any Governmental Entity relating to the matters that are the subject of this Agreement, and prior to submitting any Filing, substantive written communication, correspondence or other information or response by such party or any or its Representatives, on the one hand, to any Governmental Entity, or members of the staff of any Governmental Entity, on the other, subject to Section 6.4, the submitting party shall permit the other party and its counsel a reasonable opportunity to review in advance, and consider in good faith the comments of the other party provided in a timely manner, in connection with any such Filing, communication or inquiry. Parent, in consultation with the Company, shall take the lead in coordinating communications with any Governmental Entity and developing strategy for responding to any investigation or other inquiry by any Governmental Entity related to any of the Requisite Regulatory Approvals or other third-party Consents. Subject to Section 6.4 and the terms and conditions of the Confidentiality Agreement, the Company and Parent shall coordinate and cooperate fully with each other in exchanging such information and providing such assistance as the other party may reasonably request in connection with the foregoing (including in seeking early termination of any applicable waiting periods under the HSR Act). To the extent practicable under the circumstances, none of the parties hereto shall agree to participate in any substantive meeting or conference with any Governmental Entity, or any member of the staff of any Governmental Entity, in respect of any Filing, proceeding, investigation (including any settlement of the investigation), litigation, or other inquiry related to the Merger unless it consults with the other party in advance and, where permitted, allows the other party to participate. Neither party shall be required to comply with any of the foregoing provisions of this Section 6.5(f) to the extent that such compliance would be prohibited by applicable Law. The parties further covenant and agree not to voluntarily extend any waiting period associated with any Consent of any Governmental Entity or enter into any agreement with any Governmental Entity not to consummate the Merger and the other transactions contemplated hereby, except with the prior written consent of the other party hereto.

(g) Each of the Company and Parent may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 6.5 as "Antitrust Counsel Only Material." Such materials and the information contained therein shall be given only to the outside antitrust counsel of the recipient and, subject to any additional confidentiality or joint defense agreement the parties may enter into, will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (the Company or Parent, as the case may be) or its legal counsel. Notwithstanding anything to the contrary in this Section 6.5, materials provided to the other party or its outside counsel may be redacted (i) to remove references concerning valuation, (ii) as necessary to comply with contractual arrangements, (iii) as necessary to address reasonable attorney-client or other privilege or confidentiality concerns and (iv) to remove references concerning pricing and other competitively sensitive terms from an antitrust perspective in the Contracts of the Company, Parent and their respective Subsidiaries.

(h) Notwithstanding anything herein to the contrary, in no event shall Parent or its Affiliates or the Company or its Affiliates be required to agree to take or enter into any action which is not conditioned upon the Closing.

Section 6.6 Employee Matters.

(a) Until the first anniversary of the Effective Time (the "Benefits Continuation Period"), the Surviving Company shall provide, or cause to be provided, for those employees of the Company and its Subsidiaries who continue as employees of the Surviving Company or any of its Subsidiaries during all or a portion of the Benefits Continuation Period (the "Continuing Employees"), compensation (including base salary, bonus and other incentive compensation opportunities but excluding equity-based compensation) and employee benefits that in the aggregate shall not be any less favorable than the compensation and employee benefits provided by the Company or the applicable Subsidiary to the Continuing Employees immediately prior to the Effective Time. Nothing herein shall be deemed to be a guarantee of employment for any current or former employee of the Company or any of its Subsidiaries, or other than as provided in any applicable employment agreement or other Contract, to restrict the right of Parent or the Surviving Company to terminate the employment of any such employee.

(b) The Surviving Company shall (i) waive any applicable pre-existing condition exclusions and waiting periods with respect to participation and coverage requirements in any replacement or successor welfare benefit plan of the Surviving Company in which a Continuing Employee is eligible to participate following the Effective Time to the extent such exclusions or waiting periods were inapplicable to, or had been satisfied by, such Continuing Employee immediately prior to the Effective Time under the analogous Company Benefit Plan in which such Continuing Employee participated, (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Effective Time (to the same extent such credit was given under the analogous Company Benefit Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements and (iii) recognize service prior to the Effective Time with the Company or any of its Subsidiaries for purposes of eligibility to participate, vesting, determination of level of benefits and benefits accrual to the same extent such service was recognized by the Company or any of its Subsidiaries under the analogous Company Benefit Plan in which such Continuing Employee participated immediately prior to the Effective Time; provided, however, that the foregoing shall not apply to the extent it would result in any duplication of benefits for the same period of service; provided, further, that the Surviving Company shall not be obligated to provide credit for years of service for purposes of retirement eligibility vesting under any Parent equity-based compensation plan or for benefit accrual purposes under any defined benefit pension plan maintained by the Surviving Company or its Subsidiaries prior to the date on which the Continuing Employee actually becomes a participant in such plan.

(c) From and after the Effective Time, Parent shall honor, and shall cause its Subsidiaries to honor, in accordance with its terms, (i) each existing employment, change in control, severance and termination protection plan, policy or agreement of or between the Company or any of its Subsidiaries and any current or former officer, director or employee identified in Section 6.6(c)(i) of the Company Disclosure Letter, (ii) subject to Section 2.5, all obligations in effect as of the Effective Time under any Company Stock Plan or bonus or bonus

deferral plans, programs or agreements of the Company or any of its Subsidiaries identified in Section 6.6(c)(ii) of the Company Disclosure Letter and (iii) all obligations in effect as of the Effective Time pursuant to outstanding retention plans, programs or agreements identified in Section 6.6(c)(iii) of the Company Disclosure Letter, and all vested and accrued benefits under any Company Benefit Plan.

(d) Parent shall cause the Surviving Company and each of its Subsidiaries, for a period commencing at the Effective Time and ending ninety (90) days thereafter, not to effectuate a "plant closing" or "mass layoff," as those terms are defined in WARN, affecting in whole or in part any site of employment, facility, or operating unit of the Surviving Company or any of its Subsidiaries without complying with all provisions of WARN.

(e) Notwithstanding any other provision of this Agreement to the contrary, subject to any agreements with Continuing Employees and applicable Law, Parent shall or shall cause the Surviving Company to provide Continuing Employees whose employment terminates during the Benefits Continuation Period with severance benefits no less favorable than the severance benefits that would have been provided pursuant to the terms of the Company's severance plans or commitments identified in Section 6.6(e) of the Company Disclosure Letter applicable to such Continuing Employee immediately prior to the Effective Time.

(f) Nothing contained in this Agreement, whether express or implied, (i) shall be treated as an amendment or other modification of any Company Benefit Plan, (ii) shall create any third-party beneficiary rights in any Person or (iii) subject to the requirements of this Section 6.6, shall limit the right of Parent or the Surviving Company or any of its Subsidiaries to amend, terminate or otherwise modify any Company Benefit Plan following the Closing Date.

Section 6.7 Expenses. Whether or not the Merger is consummated, all Expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such Expenses, except as provided in Section 6.14(c) and Section 6.14(d). As used in this Agreement, "Expenses" includes all out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, experts and consultants to a party and its Affiliates) incurred by a party or on its behalf in connection with or related to the authorization, preparation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby.

Section 6.8 Directors' and Officers' Indemnification and Insurance.

(a) From and after the Effective Time, Parent shall, and shall cause the Surviving Company to, to the fullest extent the Company would be permitted to do so by Law (including to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors), indemnify, defend and hold harmless (and promptly advance expenses from time to time as incurred to the fullest extent permitted by Law, provided, that the Person to whom expenses are advanced provides a reasonable and customary undertaking (which shall not include posting of any collateral) to repay such advances, if it is ultimately determined that such Person is not entitled to indemnification) the present and former

directors and officers of the Company or any of its Subsidiaries, any Person acting as director, officer, trustee, fiduciary, employee or agent of another entity or enterprise (including any Company Benefit Plan) at the request of the Company (each an "Indemnified Party") from and against any and all costs or expenses (including attorneys' fees, expenses and disbursements), judgments, fines, losses, claims, damages, penalties, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, regulatory or investigative, arising out of, relating to or in connection with any circumstances, developments or matters in existence, or acts or omissions occurring or alleged to occur prior to or at the Effective Time, including the approval of this Agreement and the Merger and the other transactions contemplated hereby or arising out of or pertaining to the Merger and the other transactions contemplated hereby, whether asserted or claimed prior to, at or after the Effective Time.

(b) Subject to the following sentence, prior to the Effective Time the Company shall, in consultation with Parent, purchase a six (6) year extended reporting period endorsement with respect to the Current Insurance (a "Reporting Tail Endorsement"), and the Surviving Company shall maintain this endorsement in full force and effect for its full term; provided that the aggregate cost for such Reporting Tail Endorsement does not exceed 300% of the current annual premium paid by the Company. To the extent purchased after the date of this Agreement and prior to the Effective Time, the Reporting Tail Endorsement shall be placed through such broker(s) and with such insurance carriers as may be specified by Parent and as are reasonably acceptable to the Company.

(c) Following the Effective Time, the Surviving Company shall, and Parent shall cause the Surviving Company to, maintain in effect the provisions in its certificate of incorporation and bylaws to the extent they provide for indemnification, advancement and reimbursement of expenses and exculpation of Indemnified Parties, as applicable, with respect to facts or circumstances occurring at or prior to the Effective Time, on the same basis as set forth in the Company Charter and the Company Bylaws in effect on the date of this Agreement, to the fullest extent permitted from time to time under applicable Law, which provisions shall not be amended except as required by applicable Law or except to make changes permitted by applicable Law that would enlarge the scope of the Indemnified Parties' indemnification rights thereunder.

(d) If Parent or the Surviving Company or any of their respective successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or Surviving Company or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, Parent shall cause proper provisions to be made prior to the consummation of any transaction of the type described in clause (i) or clause (ii) of this sentence so that the successors and assigns of Parent or the Surviving Company, as the case may be, shall assume all of the obligations set forth in this Section 6.8.

(e) From and after the Effective Time, Parent and the Surviving Company shall not, directly or indirectly, amend, modify, limit or terminate the advancement and reimbursement of expenses, exculpation, indemnification provisions of the agreements listed in Section 6.8(e) of the Company Disclosure Letter between the Company or any Subsidiary and

any of the Indemnified Parties, or any such provisions contained in the Surviving Company certificate of incorporation or bylaws to the extent such provision applies to Indemnified Parties.

(f) This Section 6.8 is intended for the irrevocable benefit of, and to grant third-party rights to, the Indemnified Parties and shall be binding on all successors and assigns of Parent and the Surviving Company. The obligations of Parent under this Section 6.8 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party unless the affected Indemnified Party shall have consented in writing to such termination or modification. It is expressly agreed that each Indemnified Party shall be a third-party beneficiary of this Section 6.8, and entitled to enforce the covenants contained in this Section 6.8. If any Indemnified Party makes any claim for indemnification or advancement of expenses under this Section 6.8 that is denied by Parent and/or the Surviving Company, and a court of competent jurisdiction determines that the Indemnified Party is entitled to such indemnification, then Parent or the Surviving Company shall pay such Indemnified Party's costs and expenses, including legal fees and expenses, incurred in connection with pursuing such claim against Parent and/or the Surviving Company. The rights of the Indemnified Parties under this Section 6.8 shall be in addition to, and not in substitution for, any rights such Indemnified Parties may have under the Company Charter and the Company Bylaws, the certificate of incorporation and bylaws (or comparable organizational documents) of any of the Company's Subsidiaries, including the Surviving Company, or under any applicable Contracts, insurance policies or Laws.

(g) 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 respective Subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 6.8 is not prior to or in substitution for any such claims under such policies.

Section 6.9 Public Announcements. Parent and the Company shall issue separate press releases announcing this Agreement and the transactions contemplated hereby, which press releases shall describe the Agreement and the transactions contemplated hereby in a manner reasonably satisfactory to the other party. Following such initial press releases, Parent and the Company shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other public statements or statements to employees or independent contractors of either party with respect to the Merger and the other transactions contemplated hereby and shall not issue any such press release or make any such public statement prior to such consultation, except as such party may reasonably conclude may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system; provided, however, that the restrictions set forth in this Section 6.9 shall not apply to any release or public statement (a) made or proposed to be made by the Company in accordance with Section 6.3 or (b) in connection with any dispute between the parties regarding this Agreement, the Merger or the other transactions contemplated hereby.

Section 6.10 Notification. The Company shall promptly notify Parent, and Parent shall promptly notify the Company, of (a) any notice or other communication received by such party from any Governmental Entity in connection with the Merger and the other

transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the Merger and the other transactions contemplated hereby, if the subject matter of such communication or the failure of such party to obtain such consent would reasonably be expected to have a Company Material Adverse Effect or a Parent Material Adverse Effect, (b) any matter (including a breach of any representation, warranty, covenant or agreement contained in this Agreement) that would reasonably be expected to lead to the failure to satisfy any of the conditions to Closing in Article VII and (c) any action, 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, in each case which relates to the Merger, the Financing or the other transactions contemplated hereby. This Section 6.10 shall not constitute a covenant or agreement for purposes of Section 7.2(b) or Section 7.3(b).

Section 6.11 State Takeover Laws. The Company and Parent shall each use reasonable best efforts to ensure that no Takeover Statute is or becomes applicable to this Agreement, the Merger or the other transactions contemplated hereby. If any Takeover Statute becomes applicable to this Agreement, the Merger or the other transactions contemplated hereby, the Company and Parent shall each use reasonable best efforts to ensure that the Merger and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such Law on this Agreement, the Merger and the other transactions contemplated hereby.

Section 6.12 Delisting. Each of the parties agrees to cooperate with the others in taking, or causing to be taken, all actions necessary to delist the Company Common Stock from the NYSE and terminate its registration under the Exchange Act; provided that such delisting and termination shall not be effective until after the Effective Time.

Section 6.13 Section 16(b). The Company and Parent shall take all steps reasonably necessary to cause the transactions contemplated hereby and any other dispositions of equity securities of the Company (including derivative securities) and acquisitions of equity securities of Parent (including derivative securities) in connection with the transactions contemplated hereby by each individual who is a director or executive officer of the Company or Parent to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 6.14 Financing.

(a) From and after the date hereof, in a timely manner so as not to delay the Closing, Parent shall, and shall cause its Affiliates to, take, or cause to be taken, all actions, and to do, or cause to be done all things necessary, proper or advisable to consummate, no later than the date the Closing is required to occur pursuant to Section 1.2 hereof, the Financing contemplated by the Commitment Letter (or any Substitute Financing or other debt or equity financing), including without limitation, (i) complying with and maintaining in effect the Commitment Letter, (ii) negotiating and entering into definitive agreements with respect to the debt financing contemplated by the Commitment Letter including the terms and conditions contained in the Commitment Letter so that such agreements are in effect no later than the Closing, (iii) satisfying on a timely basis all the conditions to the financing contemplated by the Commitment Letter and the definitive agreements and (iv) accepting to the fullest extent all

"market flex" contemplated by the Commitment Letter (including the fee letter relating thereto and the definitive agreements). Parent shall, after obtaining knowledge thereof, give the Company prompt written notice of any (i) material breach or default (or any event or circumstance that, with or without notice, lapse of time or both, could reasonably be expected to give rise to any material breach or default) by any party to the Commitment Letter or any definitive document related to the Financing, (ii) actual or threatened withdrawal, repudiation or termination of the Financing by the Financing Sources, (iii) material written dispute or disagreement between or among Parent and any of the other parties to the Commitment Letter or any definitive document related to the Financing, (iv) amendment or modification of, or waiver under, the Commitment Letter or any related fee letters or (v) if for any reason Parent or Merger Sub believes in good faith that it will not be able to timely obtain all or any portion of the Financing on the terms, in the manner or from the sources contemplated by the Commitment Letter or the definitive documents related to the Financing. Parent shall keep the Company informed on a reasonably current basis of the status of its efforts to arrange the Financing contemplated by the Commitment Letter, including providing copies of all definitive agreements. Parent shall have the right from time to time to amend, replace, supplement or otherwise modify, or waive any of its rights under the Commitment Letter or the Financing arrangements, and/or substitute other debt or equity financing for all or any portion of the Financing from the same and/or alternative financing sources, provided that any such amendment, replacement, supplement or other modification to or waiver of any provision of the Commitment Letter or other Financing arrangements that amends the Financing and/or substitutes all or any portion of the Financing shall not (A) (x) include any conditions precedent that are in addition to or in the aggregate more onerous than or (y) expand upon or amend or otherwise modify in any way that is adverse to the Company or Parent the conditions precedent to the Financing as set forth in the Commitment Letter, (B) prevent or materially impede or materially delay the availability of the Financing and/or the consummation of the Merger and the transactions contemplated by this Agreement or (C) except in connection with any substitution or replacement of all or any portion of the Financing in accordance with this Section 6.14, release, repudiate, withdraw, consent to or otherwise result in the termination of the obligations of the Financing Sources under the Financing. In the event that new commitment letters are entered into in accordance with any amendment, replacement, supplement or other modification of the Commitment Letter permitted pursuant to this Section 6.14(a), such new commitment letters shall be deemed to be a part of the "Financing" and deemed to be the "Commitment Letter" for all purposes of this Agreement. Parent shall be permitted to reduce the amount of Financing in its reasonable discretion, provided that Parent shall not reduce the Financing to an amount committed below the amount that is required, together with the financial resources of Parent and Merger Sub, including cash on hand and marketable securities of Parent, the Company and their respective Subsidiaries that are committed to fund the Merger Consideration, to consummate the Merger and the transactions contemplated by this Agreement, and provided, further, that such reduction shall not (A) expand upon or amend in any way that is adverse to the Company the conditions precedent to the Financing as set forth in the Commitment Letter or (B) prevent or materially impede or materially delay the availability of the Financing and/or the consummation of the Merger and the transactions contemplated by this Agreement. If funds in the amounts set forth in the Commitment Letter, or any portion thereof, become unavailable, or it becomes reasonably likely that such funds will be unavailable to Parent on the terms and conditions set forth therein, Parent shall, and shall cause its Affiliates, as promptly as practicable following the occurrence of such

event to (i) notify the Company in writing thereof, (ii) obtain substitute financing (on terms and conditions that are not materially less favorable to Parent and Merger Sub, taken as a whole, than the terms and conditions as set forth in the Commitment Letter, taking into account any "market flex" provisions thereof) sufficient to enable Parent to consummate the Merger and the other transactions contemplated hereby in accordance with its terms (the "Substitute Financing") and (iii) obtain a new financing commitment letter that provides for such Substitute Financing and, promptly after execution thereof, deliver to the Company true, complete and correct copies of the new commitment letter and fee letter (in redacted form removing only the fee information) and related definitive financing documents with respect to such Substitute Financing. Upon obtaining any commitment for any such Substitute Financing, such financing shall be deemed to be a part of the "Financing" and any commitment letter for such Substitute Financing shall be deemed the "Commitment Letter" for all purposes of this Agreement.

(b) Notwithstanding anything contained in this Agreement to the contrary, Parent expressly acknowledges and agrees that Parent's and Merger Sub's obligations hereunder are not conditioned in any manner upon Parent or Merger Sub obtaining any financing. Each of (i) Parent's breach of any of its representations or warranties in Section 4.11 or Parent's or Merger Sub's breach of any of their respective obligations in this Section 6.14 that in either case results in the failure of Parent or Merger Sub to have sufficient cash available to pay the Merger Consideration on the date that the Closing is required to occur pursuant to Section 1.2 hereof and (ii) the failure, for any reason, of Parent and Merger Sub to have sufficient cash available on the date that the Closing is required to occur pursuant to Section 1.2 hereof and/or the failure to pay the Merger Consideration on the date that the Closing is required to occur pursuant to Section 1.2 hereof shall constitute a willful and intentional breach of this Agreement by Parent and Merger Sub.

(c) The Company shall, and shall cause its Subsidiaries to, at the sole expense of Parent, use its and their commercially reasonable efforts to provide such cooperation as may be reasonably requested by Parent in connection with the financing of the Merger and the other transactions contemplated hereby, if any, including using commercially reasonable efforts to (i) cause appropriate officers and employees to be available, on a customary and reasonable basis and upon reasonable notice, to meet with ratings agencies and prospective lenders and investors in presentations, meetings, road shows and due diligence sessions, (ii) provide reasonable assistance with the preparation of disclosure documents in connection therewith, including providing financial statements and other information relating to the Company and its Subsidiaries customarily included in such disclosure documents, and to the extent necessary, the audit and/or SAS 100 review, as appropriate thereof in accordance with GAAP and applicable Law by independent certified public accountants of Parent, (iii) provide Financing Sources with reasonable access to the properties, books and records of the Company and its Subsidiaries, execute and deliver any customary pledge or security documents or other customary definitive financing documents and certificates as may be reasonably requested by Parent and (iv) direct its independent accountants to provide customary and reasonable assistance to Parent and, solely if and to the extent that financial statements of the Company are required by Rule 3-05 and/or Article 11 of Regulation S-X to be included in the disclosure document referred to in clause (ii) above, to provide customary comfort letters and consents on customary terms and consistent with their customary practices; provided that the actions contemplated in the foregoing clauses (i)

ARTICLE VIII

TERMINATION

Section 8.1 Termination. This Agreement may be terminated and the Merger and the other transactions contemplated hereby may be abandoned at any time prior to the Effective Time, whether before or after obtaining the Company Stockholder Approval (with any termination by Parent also being an effective termination by Merger Sub):

(a)	by mutual written consent of Parent and the Company;

(b)	by either Parent or the Company, if:

(i) the Merger shall not have been consummated on or before the eight (8) month anniversary of the date hereof (the "Initial Outside Date"); provided, however, that if on the Initial Outside Date any of the conditions to Closing set forth in Section 7.1(b) or Section 7.1(c) shall not have been satisfied or duly waived by all parties but all other conditions to Closing set forth in Article VII shall be satisfied or capable of being satisfied, then the Initial Outside Date shall be extended to the ten (10) month anniversary of the date hereof if Parent or the Company notifies the other in writing on or prior to the Initial Outside Date of its election to extend the Initial Outside Date (as so extended, the " Outside Date"); provided, however, that the right to extend the Initial Outside Date or terminate this Agreement pursuant to this Section 8.1(b)(i) shall not be available to any party if its action or failure to act constitutes a material breach or violation of any of its covenants, agreements or other obligations hereunder or it has failed to perform fully its obligations under Section 6.14, and such material breach or violation or failure has been the principal cause

of and directly resulted in (1) the failure to satisfy the conditions to the obligations of the terminating party to consummate the Merger set forth in Article VII prior to the Initial Outside Date or the Outside Date or (2) the failure of the Closing to occur by Initial Outside Date or the Outside Date;

(ii) any Governmental Entity of competent jurisdiction shall have issued an Order or taken any other action permanently restraining, enjoining or otherwise prohibiting the Merger and such Order or other action shall have become final and non-appealable; provided, however, that the party seeking to terminate this Agreement pursuant to this Section 8.1(b)(ii) shall have complied with Section 6.5 of this Agreement; or

(iii) the Company Stockholder Approval shall not have been obtained upon a vote taken thereon at the Company Stockholders Meeting or at any adjournment or postponement thereof;

(i) if the Company shall have breached or failed to perform any of its representations, warranties, covenants or agreements contained in this Agreement, which breach or failure to perform (A) is incapable of being cured by the Company by the Outside Date or (B) if capable of being cured, has not been cured by the Company within forty-five (45) days following written notice to the Company from Parent or Merger Sub of such breach, and, in each case, would result in a failure of any condition set forth in Section 7.2(a) or Section 7.2(b); provided that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.1(c)(i) if it is then in material breach of any representation, warranty, covenant or agreement hereunder;

(ii) there shall have been a material and intentional breach of Section 6.2 or Section 6.3 (other than by Parent or Merger Sub); or

(iii) prior to obtaining the Company Stockholder Approval, if the Board of Directors of the Company or, if required to address any conflict of interest, any committee thereof, shall have effected a Recommendation Withdrawal; or

(d) by the Company, if Parent or Merger Sub shall have breached or failed to perform any of its representations, warranties, covenants or agreements contained in this Agreement, which breach or failure to perform (A) is incapable of being cured by Parent or Merger Sub, as the case may be, by the Outside Date or (B) if capable of being cured, has not been cured by Parent or Merger Sub, as the case may be, within forty-five (45) days following written notice to Parent or Merger Sub, as the case may be, from the Company of such breach, and, in each case, would result in a failure of any condition set forth in Section 7.3(a) or Section 7.3(b); provided that the Company shall not have the right to terminate this Agreement pursuant to this Section 8.1(d) if it is then in material breach of any representation, warranty, covenant or agreement hereunder.

Section 8.2 Effect of Termination. In the event of any termination of this Agreement as provided in Section 8.1, the obligations of the parties shall terminate and there shall be no liability on the part of any party with respect thereto, except for the confidentiality provisions of Section 6.4 and the provisions of Section 3.23, Section 4.12, Section 6.7, Section 6.14(d), this Section 8.2, Section 8.3 and Article IX, each of which shall survive the termination of this Agreement and remain in full force and effect; provided, however, that neither Parent nor the Company shall be released from any liabilities or damages (including, in the case of claims by the Company, as contemplated by Section 9.5(b)(ii)) arising out of any (i) fraud, (ii) willful and intentional breach of any representation or warranty or (iii) willful and intentional breach of any covenant or agreement contained in this Agreement (including as provided in Section 6.14(b)) prior to such termination.

Section 8.3 Termination Fee.

(a) In the event that this Agreement is terminated by Parent pursuant to Section 8.1(c)(ii) or Section 8.1(c)(iii), or is terminated pursuant to Section 8.1(b)(iii) where the Company has effected a Recommendation Withdrawal, then the Company shall promptly, but in no event later than two (2) Business Days after the date of such termination, pay or cause to be paid to Parent (or its designees) an amount in cash equal to $115,000,000 (the "Termination Fee") by wire transfer of immediately available funds to an account designated in writing by Parent.

(b) In the event that this Agreement is terminated:

(i) (A) by Parent or the Company pursuant to Section 8.1(b)(i) or (B) by Parent pursuant to Section 8.1(c)(i) and, in each case, an Acquisition Proposal was publicly proposed or announced or otherwise communicated to the Board of Directors of the Company by any Person after the date of this Agreement, or

(ii) by Parent or the Company pursuant to Section 8.1(b)(iii) and an Acquisition Proposal was publicly proposed, announced or otherwise known prior to the Company Stockholders Meeting and the Company has not effected a Recommendation Withdrawal;

then (x) the Company shall pay or cause to be paid to Parent (or its designees) an amount in cash equal to 50% of the Termination Fee (A) as a pre-condition to termination if the Company is the party seeking such termination or (B) promptly, but in no event later than two Business Days after the date of such termination by Parent and (y) if the Company enters into a definitive agreement with respect to, or consummates, any Acquisition Proposal within twelve (12) months after such termination of this Agreement, then, on the date of such entering into a definitive agreement or consummation, the Company shall pay or cause to be paid to Parent (or its designees) the remaining 50% of the Termination Fee by wire transfer of immediately available funds to an account designated in writing by Parent. For purposes of clause (y) this Section 8.3(b), each reference to "15%" in the definition of "Acquisition Proposal" shall be deemed to be a reference to "50%."

(c) The parties agree and understand that, except as contemplated by the last paragraph of Section 8.3(b), in no event shall the Company be required to pay the Termination Fee on more than one occasion. Notwithstanding anything to the contrary in this Agreement, (i) if Parent receives the Termination Fee from the Company pursuant to this Section 8.3, then, except in the case of fraud, such payment shall be the sole and exclusive remedy of Parent and Merger Sub against the Company and its Subsidiaries and their respective former, current or future officers, directors, partners, stockholders, managers, members, Affiliates and Representatives and none of the Company, any of its Subsidiaries or any of their respective former, current or future officers, directors, partners, stockholders, managers, members, Affiliates or Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby and (ii) if Parent or Merger Sub receives any payments from the Company in respect of any breach of this Agreement, and thereafter Parent is entitled to receive the Termination Fee under this Section 8.3, the amount of such Termination Fee shall be reduced by the aggregate amount of any payments made by the Company to Parent or Merger Sub in respect of any such breaches of this Agreement. The parties acknowledge that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated hereby, and that, without these agreements, the parties would not enter into this Agreement, and that any amounts payable pursuant to this Section 8.3 do not constitute a penalty. Accordingly, if the Company fails promptly to pay any amount due to Parent pursuant to this Section 8.3, it shall also pay any costs and expenses incurred by Parent or Merger Sub in connection with a legal action to enforce this Agreement that results in a judgment against the Company for such amount, together with interest on the amount of any unpaid fee, cost or expense at the publicly announced prime rate of Citibank, N.A. from the date such fee, cost or expense was required to be paid to (but excluding) the payment date.

Section 8.4 Procedure for Termination. Termination of this Agreement prior to the Effective Time shall not require the approval of the stockholders of the Company. A terminating party shall provide written notice of termination to the other parties specifying the Section or Sections pursuant to which such party is terminating the Agreement. If more than one provision in Section 8.1 is available to a terminating party in connection with a termination, a terminating party may rely on any or all available provisions in Section 8.1 for any termination.

Section 9.3 Interpretation; Construction.

(a) When a reference is made in this Agreement to a Section, clause, Annex, Exhibit or Schedule, such reference shall be to a Section or clause of or Annex or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. The phrase "the date of this Agreement" and terms of similar import, shall be deemed to refer to the date first written above. Whenever the content of this Agreement permits, the masculine gender shall include the feminine and neuter genders, and a reference to singular or plural shall be interchangeable with the other.

(b) References to any agreement or contract are to that agreement or contract as amended, modified or supplemented from time to time in accordance with the terms hereof and thereof. References to any Person include the successors and permitted assigns of that Person. References to any statute are to that statute, as amended from time to time, and to the rules and regulations promulgated thereunder. References to "$" and "dollars" are to the currency of the United States. References from or through any date mean, unless otherwise specified, from and including or through and including, respectively. The words "hereby," "herein," "hereof," "hereunder" and words of similar import refer to this Agreement as a whole (including any Schedules delivered herewith) and not merely to the specific section, paragraph or clause in which such word appears. Whenever the words "include," or "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation."

(c) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(d) No summary of this Agreement or any Exhibit attached hereto or Schedule delivered herewith prepared by or on behalf of any party shall affect the meaning or interpretation of this Agreement or any such Exhibit or Schedule.

(e) Subject to the introductory language to Article III and Article IV, each party to this Agreement has or may have set forth information in its respective disclosure letter in a section of such disclosure letter that corresponds to the section of this Agreement to which it relates. The fact that any item of information is disclosed in a disclosure letter to this

Agreement shall not constitute an admission by such party that such item is material, that such item has had or would have a Company Material Adverse Effect or Parent Material Adverse Effect, as the case may be, or that the disclosure of such be construed to mean that such information is required to be disclosed by this Agreement.

Section 9.4 Counterparts; Effectiveness. This Agreement may be executed in any number of counterparts, including by facsimile or by email with .pdf attachments, each of which shall be deemed to be an original but all of which shall constitute one and the same instrument. This Agreement shall become effective when each party has received counterparts thereof signed and delivered (by electronic communication, facsimile or otherwise) by all of the other parties.

Section 9.5 Entire Agreement; No Third-Party Beneficiaries.

(a) This Agreement, the Company Disclosure Letter, the Parent Disclosure Letter, the Exhibits attached hereto and the Confidentiality Agreement constitute the entire agreement, and supersede all prior agreements, understandings, representations and warranties, both written and oral, among the parties with respect to the subject matter hereof and thereof. Each party hereto agrees that, except for the representations and warranties contained in this Agreement, neither Parent and Merger Sub, nor the Company makes any other representations or warranties, and each hereby disclaims any other representations or warranties, express or implied, or as to the accuracy or completeness of any other information made by, or made available by, itself or any of its Representatives, with respect to, or in connection with, the negotiation, execution or delivery of this Agreement or the transactions contemplated hereby, notwithstanding the delivery or disclosure to the other or the other's Representatives of any documentation or other information with respect to any one or more of the foregoing.

(b) This Agreement shall be binding upon and inure solely to the benefit of each party except for: (i) only following the Effective Time, the right of the Company's stockholders to receive the Merger Consideration in respect of shares of Company Common Stock pursuant to Section 2.1, (ii) the right of the Company on behalf of its stockholders to pursue damages (including claims for damages based on loss of the economic benefits of the transaction to the Company's stockholders), which right is hereby expressly acknowledged and agreed by Parent and Merger Sub, (iii) the right of the Indemnified Parties to enforce the provisions of Section 6.8 only and (iv) the right of the Financing Sources to enforce the provisions of Section 9.10 and Section 9.12. The third-party beneficiary rights referenced in clause (ii) of the preceding sentence may be exercised only by the Company (on behalf of its stockholders as their agent) through actions expressly approved by the Board of Directors of the Company, and no stockholder of the Company whether purporting to act in its capacity as a stockholder or purporting to assert any right (derivatively or otherwise) on behalf of the Company, shall have any right or ability to exercise or cause the exercise of any such right.

(c) The representations and warranties in this Agreement are the product of negotiations among the parties and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties in accordance with Section 9.9 without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the

parties of risks associated with particular matters regardless of the Knowledge of any of the parties. Consequently, Persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 9.6 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Merger or the other transactions contemplated hereby are not affected in any manner materially adverse to any party. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the Merger and the other transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 9.7 Assignment . Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void. This Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

Section 9.8 Modification or Amendment. Subject to the provisions of applicable Laws, at any time prior to the Effective Time, the parties hereto may modify or amend this Agreement, by written agreement executed and delivered by duly authorized officers of the respective parties.

Section 9.9 Extension; Waiver. The conditions to each of the parties' obligations to consummate the Merger are for the sole benefit of such party and may be waived by such party in whole or in part to the extent permitted by applicable Laws. At any time prior to the Effective Time, the parties may, to the extent permitted by applicable Law, (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights, nor shall any single or partial exercise by any party to this Agreement of any of its rights under this Agreement preclude any other or further exercise of such rights or any other rights under this Agreement.

Section 9.10 Governing Law and Venue; Waiver of Jury Trial; Specific Performance.

(a) This Agreement shall be deemed to be made in and in all respects shall be interpreted, construed and governed by and enforced in accordance with the Laws of the State of Delaware without regard to the conflicts of laws rules thereof.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE MERGER OR THE OTHER TRANSACTIONS CONTEMPLATED HEREBY, INCLUDING, BUT NOT LIMITED TO, ANY DISPUTE ARISING OUT OF OR RELATING IN ANY WAY TO THE COMMITMENT LETTER OR THE PERFORMANCE THEREOF. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10.

It is accordingly agreed that, except where this Agreement is terminated in accordance with Section 8.1, the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to specifically enforce the terms and provisions of this Agreement (including Section 6.14 (Financing)) and any other agreement or instrument executed in connection herewith and to thereafter cause the Merger to be consummated, in each case, if the conditions set forth in Section 7.1 and Section 7.2 have been satisfied or waived (other than conditions which by their nature cannot be satisfied until Closing, but subject to the satisfaction or waiver of those conditions at Closing), without proof of actual damages, and each party further agrees to waive any requirement for the securing or posting of any bond in connection with such remedy. Any action or proceeding for any such remedy shall be brought exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), and each party waives any requirement for the securing or posting of any bond in connection with any such remedy. The parties further agree that (x) by seeking the remedies provided for in this Section 9.10(c), 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, including monetary damages in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 9.10(c) are not available or otherwise are not granted and (y) nothing contained in this Section 9.10(c) shall require any party to institute any proceeding for (or limit any party's right to institute any

proceeding for) specific performance under this Section 9.10(c) before exercising any termination right under Section 8.1 (and pursuing damages after such termination) nor shall the commencement of any action pursuant to this Section 9.10(c) or anything contained in this Section 9.10(c) restrict or limit any party's right to terminate this Agreement in accordance with the terms of Section 8.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

(d) Each of the parties hereto (i) irrevocably consents to the service of the summons and complaint and any other process in any action or proceeding relating to the transactions contemplated hereby, on behalf of itself or its property, in accordance with Section 9.2 or in such other manner as may be permitted by Law, of copies of such process to such party, and nothing in this Section 9.10(d) shall affect the right of any party to serve legal process in any other manner permitted by Law, (ii) irrevocably and unconditionally consents and submits itself and its property in any action or proceeding to the exclusive general jurisdiction of the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) in the event any dispute arises out of this Agreement or the transactions contemplated hereby, or for recognition and enforcement of any judgment in respect thereof, (iii) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iv) agrees that any actions or proceedings arising in connection with this Agreement or the transactions contemplated hereby shall be brought, tried and determined only in the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), (v) 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 (vi) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated hereby in any court other than the aforesaid courts. Each of Parent, Merger Sub and the Company agrees that a final judgment in any action or proceeding in such court 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 Law.

Section 9.11 Obligation of Parent and of the Company. Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires a Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause such Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Company to cause such Subsidiary to take such action.

Section 9.12 Financing Sources Arrangements. Notwithstanding anything contained herein to the contrary, including Section 9.10, each of the parties hereto agrees (a) that it will not bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against any of the Financing Sources in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including but not limited to, any dispute arising

INDEMNIFICATION

Section 1. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved (including, without limitation, as a witness) in any

A-2

actual or threatened action, suit, or proceeding, whether civil, criminal, administrative, or investigative (hereinafter a "proceeding"), by reason of the fact that he or she is or was a director, officer, employee or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, limited liability company, joint venture, trust, or other enterprise, including service with respect to an employee benefit plan (hereinafter an "Indemnitee"), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while so serving, shall be indemnified and held harmless by the Corporation to the full extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), or by other applicable law as then in effect, against all expense, liability, and loss (including attorneys' fees and related disbursements, judgments, fines, excise taxes, and penalties under the Employee Retirement Income Security Act of 1974, as amended from time to time ("ERISA"), penalties, and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such Indemnitee in connection therewith, and such indemnification shall continue as to a person who has ceased to be a director, officer, employee, agent, partner, member or trustee and shall inure to the benefit of his or her heirs, executors, and administrators. Each person who is or was serving as a director, officer, employee or agent of a subsidiary of the Corporation shall be deemed to be serving, or have served, at the request of the Corporation. Any indemnification (but not advancement of expenses) under this Article IX (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, as the same exists or hereafter may be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment). Such determination shall be made with respect to a person who is a director or officer at the time of such determination (a) by a majority vote of the directors who were not parties to such proceeding (the "Disinterested Directors"), even though less than a quorum, (b) by a committee of Disinterested Directors designated by a majority vote of Disinterested Directors, even though less than a quorum, (c) if there are no such Disinterested Directors, or if such Disinterested Directors so direct, by independent legal counsel in a written opinion, or (d) by the stockholders.

Section 2. Advancement of Expenses. Expenses (including attorneys' fees, costs, and charges) incurred by an Indemnitee in defending a proceeding shall be paid by the Corporation in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that such Indemnitee is not entitled to be indemnified by the Corporation as authorized in this Article IX. The majority of the Disinterested Directors (or a committee thereof) may, in the manner set forth above, and upon approval of such Indemnitee, authorize the Corporation's counsel to represent such person in any proceeding, whether or not the Corporation is a party to such proceeding.

Section 3. Procedure for Indemnification. Any indemnification or advance of expenses (including attorneys' fees, costs, and charges) under this Article IX shall be made

A-3

promptly, and in any event within thirty days upon the written request of the Indemnitee (and, in the case of advance of expenses, receipt of a written undertaking by or on behalf of Indemnitee to repay such amount if it shall ultimately be determined that Indemnitee is not entitled to be indemnified therefore pursuant to the terms of this Article IX). The right to indemnification or advances as granted by this Article IX shall be enforceable by the Indemnitee in any court of competent jurisdiction, if the Corporation denies such request, in whole or in part, or if no disposition thereof is made within thirty days. Such person's reasonable costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses (including attorney's fees, costs, and charges) under this Article IX where the required undertaking, if any, has been received by the Corporation) that the claimant has not met the standard of conduct set forth in the DGCL, as the same exists or hereafter may be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, its independent legal counsel, and its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, as the same exists or hereafter may be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), nor the fact that there has been an actual determination by the Corporation (including its Board of Directors, its independent legal counsel, and its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 4. Other Rights; Continuance of Right to Indemnification. The indemnification and advancement of expenses provided by this Article IX shall not be deemed exclusive of any other rights to which a person seeking indemnification or advancement of expenses may be entitled under any law (common or statutory), bylaw, agreement, vote of stockholders or Disinterested Directors, or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding office or while employed by or acting as agent for the Corporation, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the estate, heirs, executors, and administers of such person. All rights to indemnification under this Article IX shall be deemed to be a contract between the Corporation and each director, officer, employee or agent of the Corporation who serves or served in such capacity at any time while this Article IX is in effect. Any repeal or modification of this Article IX or any repeal or modification of relevant provisions of the DGCL or any other applicable laws shall not in any way diminish any rights to indemnification of such person or the obligations of the Corporation arising hereunder with respect to any proceeding arising out of, or relating to, any actions, transactions, or facts occurring prior to the final adoption of such modification or repeal. For the purposes of this Article IX, references to "the Corporation" include all constituent corporations absorbed in a consolidation or merger as well as the resulting or surviving corporation, so that any person who is or was a director, officer, employee or agent of such a constituent corporation or is or was

A-4

serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise shall stand in the same position under the provisions of this Article IX, with respect to the resulting or surviving corporation, as he or she would if he or she had served the resulting or surviving corporation in the same capacity.

Section 5. Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a director, officer, employee or agent of the Corporation or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise against any expense, liability, or loss asserted against him or her and incurred by him or her in any such capacity, whether or not the Corporation would have the power to indemnify such person against such expense, liability, or loss under the DGCL.

Section 6. Reliance. Persons who after the date of the adoption of this provision become or remain directors, officers, employees or agents of the Corporation or who, while a director, officer, employee or agent of the Corporation, become or remain a director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advancement of expenses, and other rights contained in this Article IX in entering into or continuing such service. The rights to indemnification and to the advance of expenses conferred in this Article IX shall apply to claims made against an Indemnitee arising out of acts or omissions that occurred or occur both prior and subsequent to the adoption hereof.

Section 7. Savings Clause. If this Article IX or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each person entitled to indemnification under the first paragraph of this Article IX as to all expense, liability, and loss (including attorneys' fees and related disbursements, judgments, fines, ERISA excise taxes and penalties, other penalties, and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification is available to such person pursuant to this Article IX to the full extent permitted by any applicable portion of this Article IX that shall not have been invalidated and to the full extent permitted by applicable law.

ARTICLE X

AMENDMENT

The Corporation reserves the right to amend this Certificate of Incorporation in any manner permitted by the DGCL and all rights and powers conferred herein on stockholders, directors and officers, if any, are subject to this reserved power.
