AGREEMENT AND PLAN OF MERGER, dated as of July 9, 2012 (this “Agreement”), among WELLPOINT, INC., an Indiana corporation (“Purchaser”), WELLPOINT MERGER SUB, INC., a Delaware corporation and an indirect wholly owned Subsidiary (as defined in Section 8.14(aa)) of Purchaser (“Merger Sub”), and AMERIGROUP CORPORATION, a Delaware corporation (“Company”).

WITNESSETH:

WHEREAS, the respective Boards of Directors (as defined in Section 8.14(f)) of Purchaser and Company deem it advisable and in the best interests of each corporation and its shareholders and stockholders, respectively, that Purchaser and Company engage in a business combination;

WHEREAS, the combination of Purchaser and Company shall be effected by the terms of this Agreement through a merger as outlined below;

WHEREAS, in furtherance thereof, the respective Boards of Directors of Purchaser, Merger Sub and Company have adopted or approved this Agreement, pursuant to which Merger Sub will be merged with and into Company on the terms and subject to the conditions set forth in this Agreement (the “Merger”), with each share of common stock, $0.01 par value, of Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (as defined in Section 1.3) (other than (a) Company Treasury Shares (as defined in Section 1.8(b)), (b) shares of Company Common Stock owned by Purchaser or Merger Sub, (c) shares of Company Common Stock owned by any Subsidiary of either Company or Purchaser (other than Merger Sub) and (d) Dissenting Shares (as defined in Section 1.9)) being converted into the right to receive $92.00 in cash, without interest;

WHEREAS, as a condition and inducement to Purchaser’s willingness to enter into this Agreement, concurrently with the execution and delivery of this Agreement, each of James G. Carlson, James W. Truess and Richard C. Zoretic has executed and delivered an employment agreement with Purchaser; and

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

THE MERGER

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

Section 1.2 Closing. Subject to the terms and conditions hereof, the closing of the Merger and the transactions contemplated by this Agreement (the “Closing”) will take place on the Business Day (as defined in Section 8.14(g)) after the satisfaction or waiver (subject to applicable Law (as defined in Section 8.14(o))) of the conditions set forth in Article VI (other than any such conditions which by their terms cannot be satisfied until the Closing Date (as defined below), which shall be required to be so satisfied or waived (subject to applicable Law) on the Closing Date) unless another time or date is agreed to in writing by the parties hereto (the actual time and date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of Linklaters LLP, 1345 Avenue of the Americas, New York, New York, unless another place is agreed to in writing by the parties hereto.

Section 1.3 Effective Time. At the Closing, the parties shall file a certificate of merger (the “Certificate of Merger”) in such form as is required by and executed in accordance with the relevant provisions of the DGCL. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such subsequent time as Purchaser and Company shall agree and as shall be specified in the Certificate of Merger (the date and time the Merger becomes effective being the “Effective Time”).

Section 1.4 Effects of the Merger. At and after the Effective Time, the Merger will have the effects set forth in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of Company and Merger Sub shall be vested in the Surviving Corporation, and all debts, liabilities and duties of Company and Merger Sub shall be the debts, liabilities and duties of the Surviving Corporation.

Section 1.5 Certificate of Incorporation. Subject to Section 5.6, at the Effective Time, the certificate of incorporation of 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 Corporation until thereafter changed or amended as provided by the DGCL or therein.

Section 1.6 Bylaws. Subject to Section 5.6, 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 Corporation, until thereafter changed or amended as provided by the DGCL, the certificate of incorporation of the Surviving Corporation and such bylaws.

Section 1.7 Directors and Officers of Surviving Corporation. The directors of Merger Sub as of the Effective Time shall serve as directors of the Surviving Corporation until the earliest of their death, resignation or removal or otherwise ceasing to be a director or until their respective successors are duly elected or appointed and qualified. The persons designated by the Board of Directors of Merger Sub prior to the Effective Time shall serve as the officers of the Surviving Corporation, until the earliest of their death, resignation or removal or otherwise ceasing to be an officer or until their respective successors are duly elected or appointed and qualified.

Section 1.8 Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of Company, Purchaser, Merger Sub or any holder of any shares of Company Common Stock:

(a) All shares of Company Common Stock that are held by Purchaser or Merger Sub immediately prior to the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, shall be canceled and shall cease to exist and no cash, shares of common stock, $0.01 par value, of Purchaser (“Purchaser Common Stock”) or other consideration shall be delivered in exchange therefor.

(b) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) shares of Company Common Stock that are held by Company as treasury stock (the “Company Treasury Shares”), (ii) shares of Company Common Stock beneficially owned by Purchaser or Merger Sub, (iii) shares of Company Common Stock beneficially owned by any Subsidiary of either Company or Purchaser (other than Merger Sub) and (iv) Dissenting Shares) shall be converted at the Effective Time into the right to receive $92.00 in cash, without interest (the “Merger Consideration”). Upon such conversion, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each Company Certificate (as defined in Section 1.10) or Book-Entry Share (as defined in Section 1.10) shall thereafter represent the right to receive the Merger Consideration upon the surrender of the Company Certificate or Book-Entry Share in accordance with the terms hereof.

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

(d) Each share of Company Common Stock beneficially owned by any Subsidiary of either Company or Purchaser (other than Merger Sub) immediately prior to the Effective Time shall be converted into such number of shares of stock of the Surviving Corporation such that each Subsidiary owns the same percentage of the outstanding capital stock of the Surviving Corporation immediately following the Effective Time as such Subsidiary owned in Company immediately prior to the Effective Time.

(e) Each of the Company Treasury Shares shall continue to be held as shares in the treasury of the Surviving Corporation.

Section 1.9 Dissenter’s Rights. Notwithstanding anything in this Agreement to the contrary, any shares of Company Common Stock outstanding immediately prior to the Effective Time and held by any Person (as defined in Section 8.14(w)) who has not voted in favor of the Merger, who is entitled to demand and who has properly demanded in writing appraisal for such shares in accordance with Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration pursuant to this Article I unless and until the holder thereof (“Dissenting Stockholder”) shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal of such shares of Company Common Stock held by such holder under Section 262 of the DGCL, and any Dissenting

Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL with respect to shares of Company Common Stock owned by such Dissenting Stockholder. If any Person who otherwise would be deemed a Dissenting Stockholder shall have failed to properly perfect or shall have effectively withdrawn or lost the right to dissent with respect to any shares of Company Common Stock, such shares of Company Common Stock shall thereupon be treated as though such shares of Company Common Stock had been converted into the right to receive the Merger Consideration pursuant to Section 1.8 hereof. Company shall give Purchaser (a) prompt notice of any written demands for appraisal, attempted withdrawals of such demands and any other instruments served pursuant to applicable Law received by Company relating to stockholders’ rights of appraisal and (b) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands for appraisal under the DGCL. Prior to the Effective Time, Company shall not, except with the prior written consent of Purchaser, make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal of any such demands.

Section 1.10 Paying Agent. Prior to the Effective Time, Purchaser shall appoint American Stock Transfer & Trust Company, LLC, or with Company’s prior approval (which approval shall not be unreasonably withheld, delayed or conditioned), another bank or trust, to act as paying agent (the “Paying Agent”) for the purpose of exchanging certificates (the “Company Certificates”) or shares of Company Common Stock held in book-entry form (“Book-Entry Shares”) which, in either case, immediately prior to the Effective Time evidenced shares of Company Common Stock, for the Merger Consideration.

Section 1.11 Company Stock Options and Other Stock Awards.

(a) Each stock option (the “Company Stock Options”) granted under the Amerigroup Corporation 2009 Equity Incentive Plan, the Amerigroup Corporation Amended and Restated 2005 Equity Incentive Plan, the Amerigroup Corporation 2003 Equity Incentive Plan and the Amerigroup Corporation 2000 Equity Incentive Plan (each, a “Company Stock Plan,” and collectively, the “Company Stock Plans”) that as of the Effective Time is outstanding and vested by its terms (including by reason of the transactions contemplated by this Agreement), shall be cancelled and converted into the right at the Effective Time to receive an amount (if positive), payable in cash, equal to the product of (i) the total number of shares of Company Common Stock subject to such Company Stock Option multiplied by (ii) the excess, if any, of the amount of the Merger Consideration over the per share exercise price of such Company Stock Option (with the aggregate amount of such payment rounded down to the nearest cent).

(b) Each Company Stock Option that as of the Effective Time is outstanding but unvested by its terms, shall be converted as of the Effective Time into a stock option to acquire a number of shares of Purchaser 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 Stock Option immediately prior to the Effective Time multiplied by (ii) the Equity Exchange Ratio (as defined below), at an exercise price per share (rounded up to the nearest whole cent) equal to (x) the exercise price applicable to such Company Stock Option immediately prior to the Effective Time divided by (y) the Equity Exchange Ratio (each, a “Converted Option”). The “Equity Exchange Ratio” shall mean the Merger Consideration divided by the volume-weighted average price of the Purchaser Common Stock on the New York

Stock Exchange Inc. (“NYSE”) for the five consecutive trading days ending on the last trading day preceding the Closing Date. The terms and conditions of the Converted Options shall otherwise remain the same as the terms and conditions (including vesting schedules) applicable to the Company Stock Options under the Company Stock Plan and award agreements pursuant to which such Company Stock Options were granted.

(c) For purposes hereof, all shares of restricted Company Common Stock, together with all other awards of shares of Company Common Stock subject to vesting or future issuance under any Company Stock Plan, including without limitation stock appreciation rights, restricted stock units, performance stock units and deferred stock awards (but not including Company Stock Options or awards under the Company ESPP (as defined in Section 4.1(b)(ii)), shall be referred to as “Other Stock Awards.”

(d) Each Other Stock Award that as of the Effective Time is outstanding and vested by its terms (including by reason of the transactions contemplated by this Agreement), shall be cancelled and converted into the right to receive an amount, payable in cash, equal to the product of (i) the total number of shares of Company Common Stock subject to such Other Stock Award multiplied by (ii) the Merger Consideration.

(e) Each Other Stock Award that as of the Effective Time is outstanding but unvested, shall be converted as of the Effective Time into a right or award with respect to a number of shares of Purchaser Common Stock (a “Converted Other Stock Award”) equal to the product of (i) the number of shares of Company Common Stock subject to such Other Stock Award multiplied by (ii) the Equity Exchange Ratio; provided that any fractional shares resulting from such multiplication shall be rounded down to the nearest whole share. The terms and conditions of the Converted Other Stock Award shall otherwise remain the same as the terms and conditions (including vesting schedules) applicable to the Other Stock Awards under the Company Stock Plan and award agreements pursuant to which such Other Stock Awards were granted.

(f) Effective as of immediately prior to the Effective Time but subject to the occurrence of the Closing, the “Offering Period” within the meaning of the Company ESPP shall terminate, shares of Company Common Stock shall be purchased under the Company ESPP on behalf of the respective Company ESPP participants on the same basis as if the Offering Period had expired on its originally scheduled date but treating the Closing Date as the “Exercise Date” within the meaning of the Company ESPP, and the shares of Company Stock so purchased shall be cancelled effective as of the Effective Time and converted into a right of each respective Company ESPP participant to receive from the Company an amount in cash equal to (A) the total number of shares of Company Common Stock purchased on his or her behalf in accordance with this Section 1.11(f) multiplied by (B) the Merger Consideration.

(g) At the Effective Time, all of the Converted Options and Converted Other Stock Awards shall be assumed in full by Purchaser. From and after the Effective Time, all references to Company in the Company Stock Plans and in any award agreements granting Company Stock Options or Other Stock Awards shall be deemed to refer to Purchaser. Purchaser shall take all actions with respect to the Company Stock Plans, and the Converted Options and Converted Other Stock Awards, that are necessary to implement the provisions of this Section

1.11, including all corporate action necessary to reserve for issuance a sufficient number of shares of Purchaser Common Stock for delivery upon exercise of the Converted Options or future issuance under the Converted Other Stock Awards. Purchaser shall take all actions reasonably necessary to cause the registration of the shares of Purchaser Common Stock subject to the Converted Options or Converted Other Stock Awards to become effective as part of a registration statement on Form S-8 (or any successor form, or if Form S-8 is not available, other appropriate forms) with respect to the shares of Purchaser Common Stock subject to the Converted Options or Converted Other Stock Awards promptly, but in any event within one (1) Business Day, following the Effective Time; and, thereafter, Purchaser shall deliver or make available to holders of Converted Options or Converted Other Stock Awards any applicable prospectus and shall use reasonable best efforts to maintain the effectiveness of such registration statement or registration statements, including the current status of any related prospectus, for so long as the Converted Options or Converted Other Stock Awards remain outstanding.

(h) Company and Purchaser shall take all steps reasonably necessary to cause the transactions contemplated hereby and any other dispositions of equity securities of Company (including derivative securities) and acquisitions of equity securities of Purchaser (including derivative securities) in connection with the transactions contemplated hereby by each individual who is a director or executive officer of Company or Purchaser to be exempt under Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended and including all rules and regulations promulgated thereunder (the “Exchange Act”).

(i) As soon as practicable after the Effective Time, Purchaser shall deliver or cause to be delivered to each holder of Converted Options or Converted Other Stock Awards an appropriate notice setting forth such holder’s rights pursuant to any Company Stock Plans, after giving effect to the transactions hereunder.

(j) Company, including the Board of Directors of Company and any committee or administrator acting on behalf of Company or the Board of Directors of Company, shall not hereafter take any action to accelerate the vesting or exercisability, or otherwise amend, modify or change the terms, of any Company Stock Options or Other Stock Awards. At or prior to the Effective Time, Company, the Board of Directors of the Company or any committee or administrator acting on behalf of Company or the Board of Directors of Company, as applicable, shall adopt any resolutions and take any actions which are reasonably necessary to effectuate the provisions of this Section 1.11. Company shall take all reasonable actions necessary to ensure that from and after the Effective Time neither Purchaser nor the Surviving Corporation shall be required to deliver shares of Company Common Stock or other capital stock of Company to any Person pursuant to or in settlement of Company Stock Options or Other Stock Awards.

(k) It is the intent of Purchaser and Company that the treatment of Company Stock Awards contemplated in this Section 1.11 be in a manner that is consistent with the requirements of Section 409A of the Code (as defined in Section 2.8). Any cash payment under this Section 1.11 will be subject to applicable Tax (as defined in Section 8.14(cc)) withholdings.

Section 1.12 Certain Adjustments. If, between the date hereof and the Effective Time, the outstanding Purchaser Common Stock or Company Common Stock shall have been changed into a different number of shares or different class by reason of any reclassification,

recapitalization, stock split, split-up, combination or exchange of shares or a stock dividend or dividend payable in any other securities shall be declared with a record date within such period, or any similar event shall have occurred, the Merger Consideration and the Equity Exchange Ratio and other similarly dependent terms shall be equitably adjusted to provide to the holders of Company Common Stock, Company Stock Options and Other Stock Awards the same economic effect as contemplated by this Agreement prior to such event.

ARTICLE II

EXCHANGE OF COMPANY COMMON STOCK

Section 2.1 Exchange Fund. At or prior to the Effective Time, Purchaser shall deposit with the Paying Agent, in trust for the benefit of holders of shares of Company Common Stock, cash in an amount sufficient to pay the aggregate Merger Consideration in respect of all shares of Company Common Stock outstanding immediately prior to the Effective Time. Any cash deposited with the Paying Agent shall hereinafter be referred to as the “Exchange Fund.” Purchaser shall cause the Paying Agent to deliver the cash contemplated to be paid pursuant to Section 1.8 out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. Purchaser shall promptly replace or restore or shall cause the prompt replacement or restoration of 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 Paying Agent to make such payments required under Section 1.8(b). Nothing contained in this Section 2.1 and no investment losses resulting from investment of the funds deposited with the Paying Agent shall diminish the rights of any holder of Company Common Stock to receive the Merger Consideration.

Section 2.2 Exchange Procedures.

(a) As soon as reasonably practicable after the Effective Time, Purchaser shall cause the Paying Agent to mail (or in the case of The Depository Trust Company on behalf of “street” holders, deliver) to each holder of record of a Company Certificate (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon delivery of the Company Certificates to the Paying Agent, and which letter shall be in customary form and have such other provisions as are reasonably satisfactory to both Company and Purchaser and (ii) instructions for effecting the surrender of such Company Certificates in exchange for the Merger Consideration. Upon surrender of a Company Certificate to the Paying Agent together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Paying Agent, the holder of such Company Certificate shall be entitled to receive in exchange therefor, and Purchaser shall cause the Paying 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 Company Certificate multiplied by (y) the Merger Consideration. No interest will be paid or will accrue on the Merger Consideration. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of Company, a check in the amount of the aggregate Merger Consideration that such holder has the right to receive pursuant to Section 1.8 may be issued and paid with respect to such Company Common Stock to such a transferee if the Company Certificate representing such shares of Company Common Stock is presented to the Paying Agent accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

(b) Notwithstanding anything to the contrary contained in this Agreement, any holder of Book-Entry Shares shall not be required to deliver a Company Certificate or an executed letter of transmittal to the Paying Agent to receive the Merger Consideration that such holder is entitled to receive pursuant to this Agreement. 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 1.8(b) shall, upon receipt by the Paying Agent of an “agent’s message” (or such other evidence, if any, of surrender as the Paying Agent may reasonably request) be entitled to receive in exchange therefor, and Purchaser shall cause the Paying 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.

Section 2.3 No Further Ownership Rights in Company Common Stock. All cash paid upon conversion of shares of Company Common Stock in accordance with the terms of Article I and this Article II shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the shares of Company Common Stock.

To the extent that amounts are so withheld by the Surviving Corporation, Purchaser or the Paying Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by the Surviving Corporation, Purchaser or the Paying Agent, as the case may be, and such amounts shall be delivered, or shall be caused to be delivered, by the Surviving Corporation, Purchaser or the Paying Agent, as the case may be, to the applicable taxing authority within the period required under applicable Law.

Purchaser has fully paid all commitment fees, and other amounts required to be paid on or prior to the date hereof in connection with the Financing.

include the Company Recommendation in the Proxy Statement or (iii) approve, adopt or recommend, or publicly propose to approve, adopt or recommend, any proposal or offer for an Alternative Transaction (any action in clauses (i), (ii) or (iii) above, a “Change in Company Recommendation”), and subject to compliance with this Section 5.1(b) and Section 7.1(h), terminate this Agreement in order to enter into a binding agreement providing for a Superior Proposal (as defined in Section 8.14(bb)), if: (A) the Board of Directors of Company reasonably determines in good faith after consultation with its outside financial advisors and outside counsel that such proposal or offer for an Alternative Transaction constitutes a Superior Proposal, (B) the Board of Directors of Company reasonably determines in good faith after consultation with its outside counsel that the failure to take such action is reasonably likely to be inconsistent with its fiduciary duties to the stockholders of Company under applicable Law, (C) the Board of Directors of Company, before effecting a Change in Company Recommendation or terminating this Agreement as provided above, gives Purchaser three (3) Business Days’ prior written notice (unless at the time such notice is otherwise required to be given there are less than three (3) Business Days prior to the Company Stockholders Meeting, in which case Company shall provide as much notice as is reasonably practicable) of its intention to do so (it being agreed that neither the delivery of such notice by Company nor any public announcement thereof that Company determines it is required to make under applicable Law shall constitute a Change in Company Recommendation unless and until the Company shall have failed at or prior to the end of the period referred to in clause (D) (and, upon the occurrence of such failure, such notice and such public announcement shall constitute a Change in Company Recommendation) to publicly announce that it (I) is recommending this Agreement and (II) has determined that such other Alternative Transaction (taking into account in (I) any modifications or adjustments made to this Agreement to which Parent has agreed in writing and in (II) any modifications or adjustments made to such other Alternative Transaction) is not a Superior Proposal and has publicly rejected such Alternative Transaction), (D) during such three (3) Business Day period (or such shorter period as specified below), Company, if requested by Purchaser, shall have engaged in good faith negotiations with Purchaser (including by making its officers and its financial and legal advisors reasonably available to negotiate) regarding any amendments to this Agreement proposed in writing by Purchaser in response to such Superior Proposal and (E) at the end of the period described in the foregoing clause (D), the Board of Directors of 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 Purchaser has agreed in writing), that such proposal continues to be a Superior Proposal and that the failure to make a Change in Company Recommendation or the failure to terminate this Agreement would be reasonably likely to be inconsistent with its fiduciary duties to the stockholders of Company under applicable Law. Any material amendment or modification to any Superior Proposal will be deemed to be a new proposal for purposes of this Section 5.1(b); provided, however, that in the event the Company seeks to make a Change in Company Recommendation as provided above, the notice period and the period during which the Company and its Representatives are required to negotiate, if requested by Purchaser, with Purchaser regarding any amendments to the terms of this Agreement proposed in writing by Purchaser in response to such new proposal pursuant to clause (D) above shall expire on the later to occur of (x) two (2) Business Days after Company provides written notice of such new proposal to Purchaser and (y) the end of the original three (3) Business Day period described in clause (D) above.

(c) Nothing contained in this Agreement shall prohibit Company from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act (including any “stop, look and listen” communication to the stockholders of Company) or (ii) making any required disclosure to the stockholders of Company if, in the good faith judgment of the Board of Directors of Company (after receiving the advice of its outside counsel), failure to make such disclosure is reasonably likely to be inconsistent with the fiduciary duties of the Board of Directors of Company to the stockholders of Company under applicable Law or (iii) informing any Person of the existence of the provisions contained in this Section 5.1 or Section 5.4.

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

Section 5.2 Access to Information.

(a) Upon reasonable notice, Company shall (and shall cause each of its Subsidiaries to) afford to the Representatives of Purchaser reasonable access during normal business hours, during the period prior to the Effective Time, to such of its properties, books, Contracts, commitments, records, officers and employees as Purchaser may reasonably request and, during such period, shall (and shall cause each of its Subsidiaries to) furnish as promptly as reasonably practicable to Purchaser consistent with its legal obligations and obligations pursuant to Contracts, all other information concerning Company and Company’s business, properties and personnel as Purchaser may reasonably request; provided, however, that Company may restrict the foregoing access to the extent that any applicable Law, treaty, rule or regulation requires such party to restrict access to any properties or information and that Purchaser shall not have access to individual performance or evaluation records, medical histories or other information that in the

reasonable opinion of 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; provided, further, that 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 Company or its 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 Company and its Subsidiaries, Purchaser and its Representatives shall not (i) unreasonably interfere with the business conducted at such property or (ii) damage any property or any portion thereof. Prior to the Effective Time, Purchaser and its Representatives shall not have the right to conduct environmental testing or sampling at any of the facilities or properties of Company or any of its Subsidiaries. Purchaser will hold any such information obtained pursuant to this Section 5.2(a) that is non-public in confidence to the extent required by, and in accordance with, the provisions of that certain Mutual Non-Disclosure Agreement, dated April 23, 2012, between Purchaser and Company (the “Confidentiality Agreement”), which shall remain in full force and effect in accordance with its terms.

(b) Prior to the Effective Time, Company and its Subsidiaries shall afford Purchaser reasonable access to its key employees for the purpose of discussing and documenting (if applicable) the terms and conditions upon which each such employee may continue his or her employment with Company and its Subsidiaries after the Effective Time.

Section 5.3 Reasonable Best Efforts.

(a) Upon the terms and subject to the conditions set forth in this Agreement, the parties shall, and shall cause their respective Subsidiaries to, use reasonable best efforts to (i) cause the conditions to Closing to be satisfied as promptly as practicable, (ii) as promptly as practicable, obtain all necessary Consents from, and provide all necessary notices to, Governmental Entities and third parties and (iii) take, or cause to be taken, all actions necessary, proper or advisable to comply promptly and fully with all legal requirements which may be imposed on such party or its Subsidiaries with respect to the Merger and the other transactions contemplated hereby and, subject to the conditions set forth in Article VI hereof, to consummate the Merger and the other transactions contemplated hereby, as promptly as practicable.

(b) Subject to Section 5.3(c) and without limiting the foregoing, Purchaser and its Affiliates and Company and its Affiliates shall take any and all actions necessary to avoid each and every impediment under any Health Care Law, Antitrust Law (as defined in Section 8.14(d)), insurance Law or other applicable Law or Order that may be asserted by or on behalf of any Governmental Entity with respect to this Agreement, the Merger and the other transactions contemplated hereby or that arises under or relates to any Contracts between Company and any Governmental Entity, so as to enable the Closing to occur as promptly as practicable, including, without limitation, any of the following actions requested by or on behalf of any Governmental Entity, or necessary or appropriate to (I) obtain all Consents under any Health Care Law, Antitrust Law, insurance Law or other applicable Law or Order and secure the expiration or termination of any applicable waiting period under the HSR Act or any other Antitrust Law; (II) resolve any objections that may be asserted by or on behalf of any Governmental Entity with

respect to the Merger and the other transactions contemplated hereby; and (III) 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:

(i) comply with all restrictions and conditions, if any, imposed, compelled, required or requested by any Governmental Entity in connection with granting any necessary Consent of any such Governmental Entity or in connection with the expiration or termination of any applicable waiting period under the HSR Act or any other Antitrust Laws or any clearance under any Health Care Laws, insurance Laws or other applicable Laws or Orders including: (I) proposing, negotiating, committing to and effecting, by consent decree, hold separate Order or otherwise, the sale, divestiture, disposition, license or other disposition of any Subsidiaries, operations, divisions, businesses, product lines, Contracts, customers or assets of Purchaser or any of its Affiliates (including Company or any of its Subsidiaries), (II) taking or committing to take such other actions that may limit or impact Purchaser’s or any of its Subsidiaries’ or Affiliates’ (including Company’s or any of its Subsidiaries’) freedom of action with respect to, or its ability to retain, any of Purchaser’s or any of its Subsidiaries’ or Affiliates’ (including Company’s or any of its Subsidiaries’) operations, divisions, businesses, products lines, Contracts, customers or assets and (III) entering into any Orders, settlements, undertakings, Contracts, consent decrees, stipulations or other agreements to effectuate any of the foregoing or in order to vacate, lift, reverse, overturn, settle or otherwise resolve any Order that prevents, prohibits, restricts or delays the consummation of the Merger and the other transactions contemplated hereby, in any case, that may be issued by any court or other Governmental Entity;

(ii) agree to (I) enter into, suspend, amend or terminate any Contract or other business relationship of Purchaser or any of its Subsidiaries or Affiliates or Company or any of its Subsidiaries or Affiliates (including any Contract with any Governmental Entity) and (II) any additional obligations relating to any Contract imposed by any Governmental Entity, in each case as may be required to obtain any necessary Consent of any Governmental Entity or to obtain expiration or termination of any applicable waiting period under the HSR Act or any other Antitrust Laws or clearance under any Health Care Laws, insurance Laws or other applicable Laws or Orders; and

(iii) oppose fully and vigorously (I) 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 (II) 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 (I) or (II) 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.

(c) Notwithstanding anything to the contrary in this Section 5.3, Purchaser shall be required to agree to any terms or conditions that, if imposed, compelled, required or requested by a Governmental Entity, would (i) impose any limitations on Purchaser’s ownership

or operation of all or any portion of its or Company’s, or any of their respective Subsidiaries’, businesses or assets, or compel Purchaser or any of its Subsidiaries to dispose of or hold separate all or any portion of its or Company’s, or any of their respective Subsidiaries’, businesses or assets, (ii) impose any limitations on the ability of Purchaser to acquire or hold or to exercise full rights of ownership of the Company Common Stock or the capital stock of the Surviving Corporation, (iii) impose any obligations on Purchaser or any of its Subsidiaries or Company or any of its Subsidiaries to maintain places of business, aggregate employment levels or lines of business, (iv) require Purchaser or any of its Subsidiaries or Company or any of its Subsidiaries to make any payments to a Governmental Entity or (v) impose any other binding obligation, restriction, requirement, limitation, qualification, condition, remedy or other action on Purchaser or any of its Subsidiaries or Company or any of its Subsidiaries unless, in the case of any such term or condition described in clauses (i) through (v) above (A) would, or would be reasonably likely to have, individually or in the aggregate, a material adverse effect on Company and its Subsidiaries, taken as a whole, or a material adverse effect on Purchaser and its Subsidiaries, taken as a whole (a “Purchaser Regulatory Material Adverse Effect”) (it being agreed that in the case of measuring a Purchaser Regulatory Material Adverse Effect (I) “Subsidiaries” shall not include Company or its Subsidiaries, (II) Purchaser Regulatory Material Adverse Effect shall be the level of, and shall be measured as to, what would be reasonably likely to have a material adverse effect on Company and its Subsidiaries, taken as a whole, and not the level or measure of what would be reasonably likely to have a material adverse effect on Purchaser and its Subsidiaries, taken as a whole, and (III) the effect shall be with respect to Purchaser and its Subsidiaries) or (B) would, or would be reasonably likely to materially impair the benefits reasonably expected to be derived by Purchaser from the transactions contemplated by this Agreement, including the Merger (to the extent not mitigated through the resolution process set forth in Section 5.3(d) below, each of (A) and (B) above, a “Burdensome Term or Condition”); provided that (x) any obligation, restriction, requirement, limitation, qualification, condition, remedy or other action required by a United States federal Governmental Entity relating to Consents required to be obtained under the HSR Act and any other United States federal Antitrust Laws or in connection with the expiration or termination of any applicable waiting period under the HSR Act or any other United States federal Antitrust Law shall be deemed not to constitute and shall not be taken into account in determining whether a Burdensome Term or Condition shall have been imposed, compelled, required or requested and (y) in determining whether a Burdensome Term or Condition shall have been imposed, compelled, required or requested, neither Company nor Purchaser shall take into account effects resulting from or arising out of changes in the business plans or operations of (1) Purchaser or its Subsidiaries that have a material effect on Purchaser’s or its Subsidiaries’ ability to satisfy or comply with any obligation, restriction, requirement, request, limitation, qualification, condition, remedy or other action of any Governmental Entity required or requested in connection with the Merger or the other transactions contemplated by this Agreement or (2) Company or its Subsidiaries, which in any case under clause (1) or (2), are proposed or agreed to by Purchaser or its Subsidiaries to be effective on and after the Merger, but not changes in the business plans or operations imposed, compelled, required or requested by a Governmental Entity whose approval is required in connection with the Merger or the other transactions contemplated by this Agreement.

(d) Prior to Purchaser being entitled to invoke the actual or potential imposition of a Burdensome Term or Condition, Purchaser shall meet with Company in order to: (i) exchange and review Purchaser’s and Company’s views as to such obligation, restriction,

requirement, request, limitation, qualification, condition, remedy or other action; and (ii) discuss any potential approaches that would avoid such obligation, restriction, requirement, request, limitation, qualification, condition, remedy or other action or mitigate its impact.

(e) Neither Company nor Purchaser shall, and each of them shall cause its Affiliates not to directly or indirectly, enter into, amend or terminate any Contract, 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 or would reasonably be expected to: (i) impose any material delay in the obtaining of, or materially increase the risk of not obtaining, any Consent 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 under the HSR Act and any other Antitrust Laws; (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) prohibit or prevent or materially delay the consummation of the Merger and the other transactions contemplated hereby.

(f) In furtherance of the foregoing, the parties shall as promptly as practicable following the date hereof 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) not later than twenty (20) Business Days following the date hereof, Purchaser filing, or causing to be filed, “Form A Statements” or similar change of control applications, with the insurance commissioners or departments of health in each jurisdiction where required by applicable insurance Law or Health Care Law seeking approval of Purchaser’s acquisition of control of each of the Company Regulated Subsidiaries which results from the Merger; (ii) not later than twenty (20) Business Days following the date hereof, Purchaser filing, or causing to be filed, any pre-acquisition notifications on “Form E” or similar market share notifications to be filed in each jurisdiction where required by applicable insurance Laws with respect to the Merger and the other transactions contemplated hereby; (iii) not later than ten (10) Business Days following the date hereof, Company and Purchaser 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 waiting period under the HSR Act; (iv) Company and Purchaser each making any other Filing that may be required under any other Antitrust Laws or by any Antitrust Authority (as defined in Section 8.14(c)); (v) not later than sixty (60) days prior to the Closing, Company and Purchaser filing any required notices to the Centers for Medicare and Medicaid Services (“CMS”), with a separate notice to the CMS Medicare Drug Benefit Group and Central Office Medicare Advantage plan manager if applicable; and (vi) Company and Purchaser each promptly making any other Filing that may be required under any Health Care Laws or insurance or other applicable Laws or by any Governmental Entity with jurisdiction over enforcement of any such Law.

(g) Company and Purchaser shall, as promptly as practicable, (i) upon the reasonable request of the other party, furnish to such party and upon any request from a Governmental Entity, furnish to such Governmental Entity, any information or documentation concerning themselves, their Affiliates, directors, officers, securityholders and Financing Parties, 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 Filing 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.

(h) Subject to applicable Law relating to the sharing of information, each of Company and Purchaser 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 hand, subject to Section 5.2, the submitting party shall permit the other party and its counsel the opportunity to review as reasonably in advance as practicable under the circumstances, and consider in good faith the comments of the other party in connection with any such Filing, communication or inquiry. Subject to Section 5.2 and the terms and conditions of the Confidentiality Agreement, Company and Purchaser 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). Each such party shall promptly inform the other parties hereto of any oral communication with, and provide copies of written communications with, any Governmental Entity regarding any Filing. 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 unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, allows the other party to participate. Neither party shall be required to comply with any of the foregoing provisions of this Section 5.3(h) 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 (including under the HSR Act) or enter into any agreement with any Governmental Entity or other third party not to consummate the Merger and the other transactions contemplated hereby, except with the prior written consent of the other party hereto. Purchaser shall have responsibility for the filing fees associated with its “Form A Statements” or similar change of control applications and its “Form E” or similar market share notifications.

(i) Each of Company and Purchaser may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 5.3 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 mutually propose and 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 (Company or Purchaser, as the case may be) or its legal counsel. Notwithstanding anything to the contrary in this Section 5.3, 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 Company, Purchaser and their respective Subsidiaries.

(j) Notwithstanding anything herein to the contrary, in no event shall (i) Purchaser or its Affiliates or Company or its Affiliates be required to agree to take or enter into any action which is not conditioned upon the Closing or (ii) without limiting the provisions of subsections (a) through (c) of this Section 5.3, Company or its Affiliates agree to any obligation, restriction, requirement, limitation, qualification, condition, remedy or other action relating to Consents required to be obtained by the parties or their respective Subsidiaries in connection with the Merger without the prior written consent of Purchaser; provided that notwithstanding the foregoing (i) it is understood and agreed that any failure by Company or its Affiliates to agree to any such obligation, restriction, requirement, limitation, qualification, condition, remedy or other action by reason of Purchaser’s withholding its written consent from Company or its Affiliates to do so shall not constitute a breach of this Section 5.3 by Company and its Affiliates and (ii) Purchaser shall be required to provide its written consent to Company or its Affiliates agreeing to any such obligation, restriction, requirement, limitation, qualification, condition, remedy or other action to the extent it would not, individually, or together with any other such obligation, restriction, requirement, limitation, qualification, condition, remedy or other action, impose a Burdensome Term or Condition.

Section 5.4 No Solicitation of Transactions. Company agrees that, from the date hereof until the earlier of the Effective Time or the date of termination of this Agreement, it shall not, and shall cause its Subsidiaries and its Subsidiaries’ Representatives retained by it or any of its Subsidiaries not to, directly or indirectly, solicit, initiate, knowingly encourage or knowingly facilitate, or furnish or disclose non-public information in furtherance of, any inquiries or the making of any proposal or offer which constitutes, or may reasonably be expected to lead to, any proposal or offer with respect to any Alternative Transaction, or negotiate or engage in discussions with any Person (other than Purchaser, Merger Sub or their respective Representatives) with respect to any Alternative Transaction; provided that, Company and its Representatives may contact any Person making such proposal and its Representatives to ascertain facts or clarify terms and conditions for the sole purpose of the Board of Directors of Company informing itself about such proposal and the Person that made it, and at any time prior to the adoption of this Agreement by Company’s stockholders (and in no event after the adoption of this Agreement by Company’s stockholders), Company may furnish information to, and negotiate or engage in discussions with, any party who delivers a bona fide written proposal for an Alternative Transaction which was made and not solicited, initiated, knowingly encouraged or knowingly facilitated by Company or its Representatives after the date hereof, if and so long as the Board of Directors of Company reasonably determines in good faith after consultation with its outside counsel that the failure to provide such information or engage in such negotiations or discussions is reasonably likely to be inconsistent with its fiduciary duties to the stockholders of Company under applicable Law and reasonably determines in good faith that such proposal is, or

is reasonably likely to lead to a Superior Proposal. Company shall notify Purchaser promptly (but in any event within 48 hours) of any such inquiries, proposals or offers received by, or any such discussions or negotiations sought to be initiated or continued with, Company or any of its Subsidiaries or any of its or its Subsidiaries’ Representatives, indicating the name of such Person and providing to Purchaser a summary of the material terms of such proposal or offer for an Alternative Transaction. Prior to providing any information or data to, or entering into any negotiations or discussions with, any Person, or making any such recommendation, in connection with a proposal or offer for an Alternative Transaction, Company shall receive from such Person an executed confidentiality agreement containing terms and provisions at least as restrictive to Company than those contained in the Confidentiality Agreement (it being understood, however, that such confidentiality agreement need not contain any obligation precluding discussions or negotiations relating to the proposal or offer from such Person and shall not contain any provision that requires exclusive negotiations with such Person). Company agrees that it will keep Purchaser informed, on a prompt basis, of the status and material terms of any such proposals or offers and the status of any material developments in respect of any such discussions or negotiations and that it will deliver to Purchaser a summary of any material changes to any such proposals or offers and all nonpublic information being furnished to such Person that was not previously provided to Purchaser. On the date hereof, Company agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Third Parties conducted prior to the date hereof with respect to any Alternative Transaction. Notwithstanding anything to the contrary contained herein, Company shall be permitted to terminate, amend, modify, waive or fail to enforce any provision of any confidentiality or standstill agreement to which it is a party if the Board of Directors of Company determines in good faith, after consultation with its outside legal counsel, that the failure to take such action is reasonably likely to be inconsistent with its fiduciary duties to the stockholders of Company under applicable Law and if Company terminates, similarly amends, waives, fails to enforce or similarly modifies the standstill provision in the Confidentiality Agreement.

Section 5.5 Employee Benefits Matters.

(a) From the Effective Time until the twelve (12) month anniversary of the Effective Time, the Surviving Corporation shall provide to those employees of Company or its Subsidiaries as of immediately prior to the Effective Time who continue as employees of Purchaser or its Subsidiaries (including the Surviving Corporation) after the Effective Time (the “Continuing Employees”) compensation and benefits that are, in the aggregate, substantially similar to or no less favorable than either (i) those provided to the employees of Company and its Subsidiaries as of the date hereof (to the extent disclosed on Schedule 3.2(w)(i)) or (ii) those generally provided to similarly situated employees of Purchaser. Nothing herein shall be deemed to be a guarantee of employment for any employee of Company or any of its Subsidiaries, or other than as provided in any applicable employment agreement or other Contract, to restrict the right of Purchaser or the Surviving Corporation to terminate the employment of any such employee.

(b) With respect to any employee benefit plan in which any Continuing Employees first become eligible to participate at or after the Effective Time (the “New Company Plans”), Purchaser shall: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to employees of Company or

its Subsidiaries under any health and welfare New Company Plans in which such employees may be eligible to participate after the Effective Time and cause deductibles, coinsurance or maximum out-of-pocket payments made by such employees during the applicable plan year in which such employee first participates in the applicable New Company Plan to reduce the amount of deductibles, coinsurance and maximum out-of-pocket payments under the New Company Plans to the extent taken account under the corresponding Company Plan in respect of the same plan year; and (ii) recognize service credited by Company or its Subsidiaries prior to the Effective Time for purposes of eligibility to participate and vesting credit (and, for purposes of severance and paid time off only, for purposes of determining the amount or level of benefit) in any New Company Plan in which such employees may be eligible to participate after the Effective Time; provided, however, that in no event shall any credit be given to the extent it would result in the duplication of benefits for the same period of service.

(c) Nothing contained in this Agreement, whether express or implied, shall (i) be treated as an amendment or other modification of any Company Plan or (ii) limit the right of Purchaser or the Surviving Corporation or any of its Subsidiaries to amend, terminate or otherwise modify any Company Plan following the Closing Date or to terminate any employee, (iii) confer upon any Person whether or not a party to this Agreement any right to employment, any right to compensation or benefits, or any other right of any kind or nature whatsoever.

(d) To the extent reasonably practicable, Company and Purchaser shall consult with each other prior to any material communications to employees or participants in the Company Plans regarding the impact of the transactions contemplated by this Agreement on Company’s compensation and benefit programs.

Section 5.6 Directors’ and Officers’ Indemnification and Insurance.

(a) The Surviving Corporation shall, and Purchaser shall cause the Surviving Corporation to indemnify, defend and hold harmless, and provide advancement of expenses to, the present and former directors, officers and employees of Company and its Subsidiaries (each such director, officer or employee an “Indemnified Person”), in each case to the fullest extent permitted by Law, including to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date hereof that increase the extent to which a corporation may indemnify its officers and directors or any Indemnified Person, 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 at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement, the performance of Company’s obligations hereunder and the consummation of the 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, the Surviving Corporation shall, and Purchaser shall cause the Surviving Corporation to, at no expense to the beneficiaries, purchase

as of the Effective Time a tail policy to the current policy of directors’ and officers’ liability insurance maintained by Company which tail policy shall be effective for a period from the Effective Time through and including the date six (6) years after the Closing Date (a “Reporting Tail Endorsement”) with respect to claims arising from facts or events that occurred on or before the Effective Time, and which tail policy shall contain coverage and amounts at least as favorable to the Indemnified Persons as the coverage currently provided by Company’s current directors’ and officers’ liability insurance policies (in the aggregate); provided, however, that in no event shall the Surviving Corporation be required to expend, for the entire tail policy, in excess of 300 per cent of the annual premium currently paid by Company for its current policies of directors’ and officers’ liability insurance (in the aggregate) (which premiums are hereby represented and warranted by the Company to currently be approximately $2,000,000 per annum); and, provided, further that, if the premium of such insurance coverage exceeds such amount, the Surviving Corporation after consultation with Company shall be obligated to obtain a policy or policies with the greatest coverage available for a cost not exceeding such amount. To the extent purchased after the date hereof and prior to the Effective Time, such insurance policies shall be placed through such broker(s) and with such insurance carriers as may be specified by Purchaser and as are reasonably acceptable to Company; provided that such insurance carrier has at least an “A” rating by A.M. Best with respect to directors’ and officers’ liability insurance and fiduciary liability insurance. Subject to both the proviso in the first sentence and to the second sentence of this Section 5.6(b), Company shall be permitted at its sole and exclusive option to purchase, after reasonable consultation with Purchaser, the Reporting Tail Endorsement (in lieu of the Surviving Corporation) prior to the Effective Time.

(c) The certificate of incorporation and bylaws of the Surviving Corporation shall include provisions for indemnification, advancement and reimbursement of expenses and exculpation of the Indemnified Persons on the same basis as set forth in the certificate of incorporation and bylaws of Company in effect on the date hereof. Following the Effective Time, the Surviving Corporation shall, and Purchaser shall cause the Surviving Corporation to, maintain in effect the provisions in its certificate of incorporation and bylaws providing for indemnification, advancement and reimbursement of expenses and exculpation of Indemnified Persons, as applicable, with respect to the facts or circumstances occurring at or prior to the Effective Time, 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 Persons’ indemnification rights thereunder.

(d) From and after the Effective Time, Purchaser and the Surviving Corporation 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 5.6(d) of the Company Disclosure Schedule between Company or any Subsidiary and any of the Indemnified Persons, or any such provisions contained in the Surviving Corporation certificate of incorporation or bylaws to the extent such provisions apply to Indemnified Persons.

(e) Any Indemnified Person wishing to claim indemnification under paragraph (a) of this Section 5.6, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Purchaser and the Surviving Corporation thereof, but the failure to so notify shall not relieve the Surviving Corporation of any liability it may have to such

Indemnified Person if such failure does not materially prejudice the indemnifying party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Purchaser or the Surviving Corporation shall have the right to assume the defense thereof and neither Purchaser nor the Surviving Corporation shall be liable to such Indemnified Persons for any legal expenses of other counsel or any other expense subsequently incurred by such Indemnified Persons in connection with the defense thereof, except that if Purchaser or the Surviving Corporation elects not to assume such defense or counsel or the Indemnified Persons advise that there are issues which raise conflicts of interest between Purchaser or the Surviving Corporation and the Indemnified Persons, the Indemnified Persons may retain counsel satisfactory to them, and Purchaser shall and shall cause the Surviving Corporation to pay all reasonable fees and expenses of such counsel for the Indemnified Persons promptly as statements therefor are received; provided, however, the Surviving Corporation shall be obligated pursuant to this paragraph (e) to pay for only one firm of counsel for all Indemnified Persons in any jurisdiction, (ii) the Indemnified Persons will cooperate in the defense of any such matter and (iii) neither Purchaser nor the Surviving Corporation shall be liable for any settlement effected without its prior written consent; and provided, further, that neither Purchaser nor the Surviving Corporation shall have any obligation hereunder to any Indemnified Person if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Indemnified Person in the manner contemplated by paragraph (a) of Section 5.6 is prohibited by applicable Law.

(f) Notwithstanding anything herein to the contrary, if any claim, action, suit, proceeding or investigation (whether arising before, at or after the Effective Time) is made against any Indemnified Persons on or prior to the sixth (6^th) anniversary of the Effective Time, the provisions of this Section 5.6 shall continue in effect until the final disposition of such claim, action, suit, proceeding or investigation.

(g) The covenants contained in this Section 5.6 are intended to be for the irrevocable benefit of and to grant third-party rights to, and shall be enforceable by, each of the Indemnified Persons and their respective heirs and legal representatives and shall not be deemed exclusive of any other rights to which an Indemnified Person is entitled, whether pursuant to Law, Contract or otherwise and shall be binding on all successors and assigns of Purchaser and the Surviving Corporation. The obligations of Purchaser under this Section 5.6 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Person unless the affected Indemnified Person shall have consented in writing to such termination or modification. It is expressly agreed that each Indemnified Person shall be a third-party beneficiary of this Section 5.6, and entitled to enforce the covenants contained in this Section 5.6. If any Indemnified Person makes any claim for indemnification or advancement of expenses under this Section 5.6 that is denied by Purchaser and/or the Surviving Corporation, and a court of competent jurisdiction determines that the Indemnified Person is entitled to such indemnification, then Purchaser or the Surviving Corporation shall pay such Indemnified Person’s reasonable costs and expenses, including reasonable legal fees and expenses, incurred in connection with pursuing such claim against Purchaser and/or the Surviving Corporation. The rights of the Indemnified Persons under this Section 5.6 shall be in addition to, and not in substitution for, any rights such Indemnified Persons may have under the certificate of incorporation and the bylaws of Company, the certificate of incorporation and bylaws (or comparable organizational documents) of any of Company’s Subsidiaries or the certificate of

incorporation and bylaws of the Surviving Corporation or under any applicable Contracts, insurance policies or Laws and Purchaser shall, and shall cause the Surviving Corporation to, honor and perform under all indemnification agreements entered into by Company or any of its Subsidiaries.

(h) In the event that Purchaser, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, Purchaser shall cause proper provision to be made prior to consummation of any transaction of the type described in clauses (i) and (ii) of this sentence so that the successors or assigns of Purchaser or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 5.6. 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 Company or any of its respective Subsidiaries for any of their respective directors, officers, employees or other Indemnified Person, it being understood and agreed that the indemnification provided for in this Section 5.6 is not prior to or in substitution for any such claims under such policies.

Section 5.7 Notification of Certain Matters. Company shall use reasonable best efforts to give prompt notice to Purchaser, and Purchaser shall use reasonable best efforts to give prompt notice to Company, to the extent that either party (a) receives, to the Knowledge of Company, in case of notices or communications received by Company or, to the Knowledge of Purchaser, in the case of notices or communications received by Purchaser, any notice or other communication 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, individually or in the aggregate, a Material Adverse Effect on Company or a Material Adverse Effect on Purchaser, (b) acquires actual knowledge of 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 VI and (c) acquires actual knowledge of any action, suits, claims, investigations or proceedings commenced or, to such party’s Knowledge, threatened in writing 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; provided, however, that the delivery of any notice pursuant to this Section 5.7 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice. Section 5.7(b) (to the extent Section 5.7(b) relates to any breach of a representation or warranty of Company or Purchaser, as applicable) and Section 5.7(c) shall not constitute a covenant or agreement for purposes of Section 6.2(b) and 6.3(b).

Section 5.8 Public Announcements. Purchaser and Company shall develop a joint communications plan and each party shall (a) ensure that all press releases and other public statements and communications (including any communications that would require a filing under Rule 14a-12 of the Exchange Act) with respect to this Agreement and the transactions contemplated hereby shall be consistent with such joint communications plan and (b) unless

otherwise required by applicable Law, court process or by obligations pursuant to any listing agreement with or rules of any securities exchange, Purchaser and Company shall consult with each other for a reasonable time before issuing any press release or otherwise making any public statement or communication (including any communication that would require a filing under Rule 14a-12 of the Exchange Act), and Purchaser and Company shall mutually agree upon any such press release or public statement or communication, with respect to this Agreement or the transactions contemplated hereby. In addition to the foregoing, except to the extent disclosed in the Proxy Statement in accordance with the provisions of Section 5.1, neither Purchaser nor Company shall issue any press release or otherwise make any public statement or disclosure concerning the other party or the other party’s business, financial condition or results of operations without the consent of the other party. Notwithstanding anything herein to the contrary, the restrictions set forth in this Section 5.8 shall not apply to any release or public statement made or proposed to be made by Company in accordance with Section 5.4 or in connection with any dispute between the parties regarding this Agreement, the Merger or the other transactions contemplated hereby.

Section 5.9 Transition Team. Promptly following execution of this Agreement, the parties shall establish a transition planning team (the “Transition Team”) comprised of an equal number of Representatives of Purchaser and Company. Subject to applicable Law, the Transition Team shall be responsible for facilitating a transition and integration planning process to facilitate the successful combination of the operations of Purchaser and Company. Subject to applicable Law, the Transition Team shall be responsible for developing, and monitoring the development of, and deliverables due under, an action plan for the combination of the businesses. This Section 5.9 shall not constitute a covenant or agreement for purposes of Section 6.2(b) or Section 6.3(b).

Section 5.10 Takeover Statutes. Company and Purchaser shall each use reasonable best efforts to, if any takeover statute or similar statute or regulation of any state becomes or may become applicable to this Agreement, the Merger or any other transactions contemplated by this Agreement, grant such approvals and take such actions as are necessary so that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such statute or regulation on this Agreement, the Merger and the other transactions contemplated by this Agreement.

Section 5.11 Withholding Certificate. Immediately prior to Closing, Company shall deliver to Purchaser a certificate, substantially in the form provided for in Sections 1.1445-2(c)(3) and 1.897-2(h) of the Treasury Regulations, establishing that the Company is not a “United States real property holding corporation” within the meaning of Section 897(c)(2) of the Code, and has not been such a United States real property holding corporation within the five (5) year period ending on the Closing Date.

Section 5.12 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 5.13 Stockholder Litigation. Company shall promptly advise Purchaser orally and in writing of any stockholder litigation against Company and/or its directors relating to this Agreement, the Merger and/or the transactions contemplated by this Agreement and shall keep Purchaser fully informed regarding any such stockholder litigation. Company shall give Purchaser the opportunity to consult with Company regarding the defense or settlement of any such stockholder litigation, shall give due consideration to Purchaser’s advice with respect to such stockholder litigation and shall not settle any such litigation prior to such consultation and consideration, provided, however, that Company will not, without Purchaser’s prior written consent (which consent shall not be unreasonably withheld or delayed), settle any such stockholder litigation.

Section 5.14 Financing.

(a) Purchaser 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 the Financing or any Substitute Financing (as defined below) as promptly as possible following the date hereof, including, (i) complying with and maintaining in effect the Commitment Letter, (ii) negotiating and entering into definitive agreements with respect to the Financing including the terms and conditions contained in the Commitment Letter so that such agreements are in effect no later than the Closing, (iii) satisfying as soon as possible and on a timely basis all the conditions to the Financing and the definitive agreements related thereto, (iv) accepting to the fullest extent all “market flex” contemplated by the Commitment Letter (or any fee letter relating thereto) and (v) enforcing its rights under the Commitment Letter in the event of a breach by the Financing Parties that could reasonably be expected to impede or delay Closing. In the event that all conditions to the Commitment Letter have been satisfied or, upon funding shall be satisfied, Purchaser and its Affiliates shall use their best efforts to cause the Financing Parties to fund on the Closing Date the Financing, to the extent the proceeds thereof are required to consummate the Merger and the other transactions contemplated hereby (including by taking enforcement action to cause the Financing Parties to fund such Financing). Purchaser shall, after obtaining Knowledge thereof, give Company prompt written notice of any (A) 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 breach or default) by a Financing Party or any party to any definitive document related to the Financing, (B) actual or threatened withdrawal, repudiation or termination of the Financing by the Financing Parties, (C) material dispute or disagreement between or among any parties to the Commitment Letter or any definitive document related to the Financing, (D) amendment or modification of, or waiver under, the Commitment Letter or any related fee letters or (E) change, circumstance or event which causes Purchaser or Merger Sub to believe 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 Financing Parties or sources contemplated by the definitive documents related to the Financing. Purchaser shall keep 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 related to the Financing. Other than as permitted pursuant to the immediately following sentence, neither Purchaser nor its Affiliates shall materially amend, modify, terminate, assign or agree to any waiver under the Commitment Letter or any related fee letters without the prior written approval of Company that would (I) reduce the aggregate amount of the Financing (including by increasing the amount of fees to be paid or original issue discount) or (II) impose

new or additional conditions or otherwise expand, amend or modify any of the conditions to the Financing, or otherwise expand, amend or modify any other provision of the Commitment Letter or the related fee letters in a manner that would reasonably be expected to (1) delay or prevent or make less likely the funding of the Financing (or satisfaction of the conditions to the Financing) on the Closing Date or (2) adversely impact the ability of Purchaser or Merger Sub, as applicable, to enforce its rights against the Financing Parties or any other parties to the Commitment Letter or the definitive agreements with respect thereto. Notwithstanding the foregoing, Purchaser shall be permitted to reduce the amount of Financing by an amount equal to the net cash proceeds received by Purchaser from any offering of (i) debt or equity securities issued by Purchaser or (ii) syndicated term loans of or guaranteed by Purchaser or any of its Subsidiaries, in each case, after the date hereof and prior to the Closing Date (provided that the funding of the Merger Consideration is described as a use of proceeds in any prospectus or term loan agreement, as applicable, related to such offering) (“Offering Proceed”), provided that Purchaser shall not reduce the Financing to an amount committed below the amount that is required, together with the financial resources of Purchaser and Merger Sub, including cash on hand and marketable securities of Purchaser, 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. 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 5.14, 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. Purchaser shall promptly deliver to Company copies of any termination, amendment, modification, waiver or replacement of the Commitment Letter or any fee letters. 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 may become unavailable to Purchaser on the terms and conditions set forth therein, in each case, other than as a result of receipt of Offering Proceeds, Purchaser shall, and shall cause its Affiliates, as promptly as practicable following the occurrence of such event to (x) notify Company in writing thereof, (y) obtain substitute financing (on terms and conditions that are not materially less favorable to Purchaser 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 Purchaser to consummate the Merger and the other transactions contemplated hereby in accordance with its terms (the “Substitute Financing”) and (z) obtain a new financing commitment letter that provides for such Substitute Financing and, promptly after execution thereof, deliver to Company true, complete and correct copies of the new commitment letter and the related fee letters (in redacted form reasonably satisfactory to the Persons providing such Substitute Financing removing only the fee information, expense information and successful syndication 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. Notwithstanding the foregoing, neither Purchaser nor any of its Affiliates shall enter into, or agree to enter into, any new commitments for any

financing that would result in a reduction of the commitments set forth in the Commitment Letter unless the conditions precedent of such new commitments are not materially less favorable to Purchaser and its Affiliates than the conditions precedent set forth in the Commitment Letter as in effect on the date hereof.

(b) Notwithstanding anything contained in this Agreement to the contrary, Purchaser expressly acknowledges and agrees that Purchaser’s and Merger Sub’s obligations hereunder are not conditioned in any manner upon Purchaser or Merger Sub obtaining the Financing, any Substitute Financing or any other financing. Purchaser’s breach of any of its representations or warranties in Section 3.1(f), Purchaser’s or Merger Sub’s breach of any of their respective obligations in this Section 5.14, the failure, for any reason, of Purchaser and Merger Sub to have sufficient cash available on the Closing Date to pay the Merger Consideration in accordance with Article II hereof (and any other amounts that may have to be paid pursuant to Section 1.11) and/or the failure to so pay the Merger Consideration on the Closing Date, in each case, shall constitute a willful and intentional breach of this Agreement by Purchaser and Merger Sub.

(c) For the period from the date hereof and the Closing, Company shall provide and shall use its commercially reasonable efforts to cause each of its Representatives, including legal, tax, regulatory and accounting, to provide, all cooperation reasonably requested by Purchaser in connection with the Financing (provided that such requested cooperation does not unreasonably interfere with the ongoing operations of Company and its Subsidiaries), including (i) as promptly as reasonably practicable providing information (financial or otherwise) relating to Company to the Persons providing the Financing (the “Financing Parties”) (including information to be used in the preparation of an information package regarding the business, operations, financial projections and prospects of Purchaser and Company customary or reasonably necessary for the completion of such Financing) to the extent reasonably requested by Purchaser to assist in preparation of customary offering or information documents to be used for the completion of the Financing, (ii) participating in a reasonable number of meetings (including customary one-on-one meetings with the lead arrangers for such Financing), presentations, road shows, drafting sessions, due diligence sessions (including accounting) and sessions with the rating agencies at times and at locations reasonably acceptable to Company, (iii) reasonably assisting in the preparation of (A) any customary offering documents, bank information memoranda, prospectuses and similar documents, which contain, to the extent reasonably available, all financial statements and other data required to be included therein, and all other data (including selected financial data) that the SEC would require in a registered offering or that would be necessary for an investment bank to receive customary “comfort” (including “negative assurance” comfort) from independent accountants in connection with a registered offering and (B) materials for rating agency presentations, (iv) reasonably cooperating with the marketing efforts for the Financing, (v) providing customary authorization letters to the Financing Parties authorizing the distribution of information to prospective lenders and containing a representation to the Financing Parties that the public side versions of such documents, if any, do not include material non-public information about Company or their respective Affiliates or securities, (vi) providing audited financial statements of Company covering the three (3) fiscal years of Company ended at least seventy-five (75) days prior to the Closing Date, unaudited financial statements (excluding footnotes) for any fiscal quarter of Company ended after the date of the most recent audited financial statements and at least forty-five (45) days prior to the Closing

Date, in each case to the extent then available, and (vii) cooperating reasonably with Financing Parties’ due diligence, to the extent customary and reasonable and to the extent not unreasonably interfering with the business of Company; provided that until the Closing occurs, Company shall (A) have no liability or any obligation under any agreement or document related to the Financing or (B) not be required to incur any other liability in connection with the Financing unless simultaneously reimbursed or reasonably satisfactorily indemnified by Purchaser. Parent shall, promptly upon request by Company, reimburse Company for all reasonable and documented out-of-pocket costs and expenses (including reasonable attorneys’ fees) incurred by Company or any of its Subsidiaries in connection with the cooperation of Company and its Subsidiaries contemplated by this Section 5.14 (without duplication of any reimbursement pursuant to the preceding sentence). Parent and Merger Sub shall, on a joint and several basis, indemnify and hold harmless Company and its Subsidiaries and their respective representatives from and against any and all liabilities, losses, damages, claims, costs, expenses (including attorneys’ fees), interest, awards, judgments and penalties suffered or incurred in connection with any Financing or other securities offering of Parent and/or its Subsidiaries or any assistance or activities provided in connection therewith.

(d) Purchaser shall pay, or cause to be paid, as the same shall become due and payable, all fees and other amounts that become due and payable prior to the Closing Date under the Commitment Letter or the related fee letters, including without limitation the fees described in the fee letter dated July 9, 2012 among Credit Suisse AG, Credit Suisse Securities (USA) LLC and Purchaser.

(e) Purchaser shall not permit the borrowing availability under that certain credit agreement, dated as of September 30, 2010, among Purchaser, Bank of America N.A. and certain other parties thereto (as amended, restated, supplemented, extended or replaced from time to time, the “Existing Credit Agreement”) to be less than $1,300,000,000 at any time prior to the Closing. Purchaser shall take all actions reasonably necessary to ensure that the Existing Credit Agreement remains in full force and effect and shall not enter into or permit any amendments, waivers or other modifications to the Existing Credit Agreement that would reasonably be likely to (i) cause the revolving loans under the Existing Credit Agreement to be unavailable to Purchaser on the Closing Date or (ii) result in the borrowing availability under the Existing Credit Agreement being less than $1,300,000,000 at any time on or prior to the Closing Date; provided that, notwithstanding the foregoing, Purchaser shall be permitted to reduce such borrowing availability by an amount equal to any Offering Proceeds received by Purchaser in excess of those required to reduce the amount of the Financing commitments to zero, provided that Purchaser shall not reduce such borrowing availability to an amount below the amount that is required, together with the financial resources of Purchaser and Merger Sub, including cash on hand and marketable securities of Purchaser, Company and their respective Subsidiaries that are committed to fund the Merger Consideration, to consummate the Merger and the transactions contemplated by this Agreement.

ARTICLE VII

TERMINATION AND AMENDMENT

Section 7.1 Termination. This Agreement may be terminated and the Merger contemplated hereby may be abandoned at any time prior to the Effective Time, whether before or after the approval by the stockholders of Company referred to in Section 5.1(b):

(a) By mutual written consent of Purchaser, Merger Sub and Company;

(b) By Purchaser or Company, if the Merger shall not have been consummated on or before June 9, 2013 (the “Initial Outside Date”); provided, however, that if on June 9, 2013 one or more of the conditions to Closing set forth in Sections 6.1(a) or 6.1(b) shall have not been satisfied or duly waived by the party entitled to the benefit of such condition

but all other conditions to Closing have been satisfied (or, in the case of conditions that by their terms are to be satisfied at the Closing, shall be capable of being satisfied on June 9, 2013), then the Initial Outside Date shall, at the option of Purchaser or Company, be extended to and including September 9, 2013 (as so extended, the “Outside Date”), if Purchaser or Company notifies the other party in writing on or prior to June 9, 2013 of its election to so extend the Initial Outside Date; and provided, further, that the right to extend the Initial Outside Date or to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to any party if such party’s action or failure to act has been the principal cause of or resulted in (i) the failure to satisfy the conditions to the obligations of the terminating party to consummate the Merger set forth in Article VI on or before the Initial Outside Date or the Outside Date or (ii) the failure of the Closing to occur by the Initial Outside Date or the Outside Date;

(d) By either Purchaser or Company, if the required approval of the stockholders of Company of the adoption of this Agreement shall not have been obtained by reason of the failure to obtain the Required Company Vote at the Company Stockholders Meeting or at any adjournment or postponement thereof;

(e) By either Purchaser or Company, if any court or other Governmental Entity of competent jurisdiction shall have issued an Order or ruling or taken any other action restraining, enjoining or otherwise prohibiting the Merger and such Order, ruling or other action is or shall have become final and nonappealable; provided that the party seeking to terminate the Agreement pursuant to this Section 7.1(e) shall have complied with Section 5.3;

(f) By Company, if prior to the Closing Date there shall have been a breach of any representation, warranty, covenant or agreement on the part of Purchaser or Merger Sub contained in this Agreement or any representation or warranty of Purchaser or Merger Sub shall have become untrue after the date hereof, which breach or untrue representation or warranty (i) would, individually or in the aggregate with all other such breaches and untrue representations and warranties, give rise to the failure of a condition set forth in Sections 6.3(a) or 6.3(b) and (ii) is incapable of being cured prior to the Closing Date by Purchaser or is not cured within forty-five (45) days of notice of such breach;

(g) By Purchaser, if prior to the Closing Date there shall have been a breach of any representation, warranty, covenant or agreement on the part of Company contained in this Agreement or any representation or warranty of Company shall have become untrue after the date hereof, which breach or untrue representation or warranty (i) would, individually or in the aggregate with all other such breaches and untrue representations and warranties, give rise to the failure of a condition set forth in Sections 6.2(a) or 6.2(b) and (ii) is incapable of being cured prior to the Closing Date by Company or is not cured within forty-five (45) days of notice of such breach; and

(h) By Company in order to concurrently enter into an agreement for an Alternative Transaction that constitutes a Superior Proposal, if prior to or concurrently with such termination, Company pays the Termination Fee (as defined in Section 7.3(b)) due under Section 7.3(b).

In the event of the termination of this Agreement pursuant to Section 7.1, the obligations of the parties under this Agreement shall terminate and there shall be no liability on the part of any party hereto, except for the obligations in the confidentiality provisions of Section 5.2, and all of the provisions of Section 3.1(i), Section 3.2(bb), Section 5.14(b), this Section 7.2, Section 7.3 and Article VIII; provided, however, that no party hereto shall be relieved or released from any liabilities or damages arising out of fraud or such party’s willful and intentional breach of any provision of this Agreement (including Sections 3.1(f) and 5.14 as provided in Section 5.14).

Section 7.3 Fees and Expenses

(a) If this Agreement is terminated pursuant to:

(i) Section 7.1(c) or 7.1(h);

(ii) Section 7.1(b) and (A) a vote of the stockholders of Company contemplated by this Agreement at the Company Stockholders Meeting to obtain the Required Company Vote has not occurred and (B) a proposal with respect to an Alternative Transaction shall have been publicly proposed or announced or otherwise submitted to the Board of Directors of Company by any Person and not irrevocably withdrawn after the date hereof and prior to the date of termination of this Agreement; or

(iii) Section 7.1(d), if a proposal with respect to an Alternative Transaction shall have been publicly proposed or announced or otherwise publicly disclosed and not irrevocably withdrawn prior to the date of the Company Stockholders Meeting,

then, (x) in the case of a termination contemplated by Section 7.3(a)(i), Company shall pay to Purchaser within one (1) Business Day following termination of this Agreement the Termination Fee by wire transfer in immediately available funds to an account specified by Purchaser and (y) in the case of a termination contemplated by Section 7.3(a)(ii) or Section 7.3(a)(iii), if, in each case, Company, within twelve (12) months after such termination either consummates an Alternative Transaction or enters into a definitive agreement with respect to an Alternative Transaction, Company shall pay to Purchaser the Termination Fee simultaneously with such consummation or entering into such definitive agreement, as the case may be, by wire transfer of immediately available funds to an account specified by Purchaser. For purposes of the foregoing clause (y), each reference to “15 per cent” in the definition of Alternative Transaction shall be deemed to be a reference to “50 per cent.”

(b) As used in this Agreement, “Termination Fee” shall mean an amount in cash equal to $146,000,000; provided, however, that if this Agreement is terminated (i) by Purchaser pursuant to Section 7.1(c) or (ii) by Company because pursuant to Section 7.1(h), in each case, in connection with the execution by Company of a binding agreement with an Excluded Party (as defined below) providing for a Superior Proposal, then “Termination Fee” shall mean an amount in cash equal to $73,000,000. “Excluded Party” means a Person from

whom Company received, during the period commencing on the date hereof and ending at 11:59 p.m., New York time, on the thirtieth (30^th) day following the date hereof (the “Excluded Period”), a bona fide written proposal with respect to an Alternative Transaction, which the Board of Directors of Company determined in good faith, prior to the end of the Excluded Period, was or was reasonably likely to lead to, a Superior Proposal.

(c) Except as otherwise specifically provided herein, each party shall bear its own expenses in connection with this Agreement and the transactions contemplated hereby.

(d) Each of Purchaser and Company agrees that the provisions contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement, that the damages resulting from the termination of this Agreement as set forth in Section 7.3(a) of this Agreement are uncertain and incapable of accurate calculation and that the amounts payable by Company pursuant to Section 7.3(a) hereof are reasonable forecasts of the actual damages which may be incurred by Purchaser under such circumstances. The amounts payable pursuant to Section 7.3(a) hereof constitute liquidated damages and not a penalty. Notwithstanding anything to the contrary in this Agreement, (i) if Purchaser receives or is entitled to receive any amounts payable pursuant to Section 7.3(a), such payment shall be the sole and exclusive remedy of Purchaser and Merger Sub against Company and its Subsidiaries and their respective former, current or future officers, directors, partners, stockholders, managers, members, Affiliates and other Representatives and none of Company, any of its Subsidiaries or any of their respective former, current or future officers, directors, partners, stockholders, managers, members, Affiliates or other Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement and (ii) if Purchaser or Merger Sub receives any payments from Company in respect of any breach of this Agreement, and thereafter Purchaser is entitled to receive any amounts payable pursuant to Section 7.3(a), any such amounts payable pursuant to Section 7.3(a) shall be reduced by the aggregate amount of any payments made by Company to Purchaser or Merger Sub in respect of any such breaches of this Agreement. If Company fails to pay to Purchaser any amounts due under Section 7.3(a) in accordance with the terms hereof, Company shall pay the costs and expenses (including reasonable legal fees and expenses) of Purchaser in connection with any action, including the filing of any lawsuit or other legal action, taken to collect payment that results in a judgment against Company for such amounts due under Section 7.3(a).

(e) Any amounts not paid when due pursuant to this Section 7.3 shall bear interest from the date such payment is due until the date paid at a rate equal to the prime rate as published in The Wall Street Journal in effect on the date of such payment.

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 hereof” 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.

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 disclosure schedule delivered herewith) and not merely to the specific section, paragraph or clause in which such word appears. Whenever the words “include,” “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 the negotiating and drafting of 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 provisions of this Agreement.

Section 8.4 Counterparts. This Agreement may be executed in one or more 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, it being understood that all the parties need not sign the same counterpart.

Section 8.5 Entire Agreement; No Third-Party Beneficiaries.

(a) This Agreement, including the schedules 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 Purchaser and Merger Sub, nor 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.

The third-party beneficiary rights referenced in clause (ii) of the preceding sentence may be exercised only by Company (on behalf of its stockholders as their agent) through actions expressly approved by the Board of Directors of Company, and no stockholder of Company whether purporting to act in its capacity as a stockholder or purporting to assert any right (derivatively or otherwise) on behalf of 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 8.9 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 hereof or as of any other date.
