“SECTION 6.19: Acquisition Proposals After Amendment.

(a)     The Company shall not, shall cause its subsidiaries and its and its subsidiaries’ directors, officers and employees not to, and shall instruct its and its subsidiaries’ Representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage, knowingly induce or knowingly facilitate (including by providing non-public information relating to the Company and its subsidiaries) the making of any Acquisition Proposal or any inquiry, offer or proposal that would reasonably be expected to lead to an Acquisition Proposal, (ii) engage or otherwise participate in any negotiations or discussions (other than, in response to a bona fide Acquisition Proposal or other inquiry, offer or proposal after the date of the Amendment that was not initiated, solicited, encouraged or facilitated in, and did not otherwise result from a, material violation of this Section 6.19, contacting such Person and its advisors for the purpose of clarifying the material terms of any such Acquisition Proposal or inquiry, offer or proposal and the likelihood and timing of consummation thereof) concerning, or provide access to its

3

properties, books and records or any confidential or nonpublic information or data to, any Person in connection with, relating to or for the purpose of encouraging or facilitating an Acquisition Proposal or any inquiry, offer or proposal that would reasonably be expected to lead to an Acquisition Proposal, (iii) approve, endorse or recommend, or propose publicly to approve, endorse or recommend, any Acquisition Proposal, or (iv) execute or enter into any Alternative Acquisition Agreement, and the Company shall not resolve or agree to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of any of the restrictions set forth in the preceding sentence by any Representatives of the Company or any of its subsidiaries shall be a breach of this Section 6.19(a) by the Company. The Company shall promptly (and in any event within twenty-four (24) hours) notify Parent orally and in writing of the receipt of any inquiries, proposals or offers, any requests for non-public information, or any requests for discussions or negotiations with the Company or any of its Representatives, in each case with respect to an Acquisition Proposal or any offer, inquiry or proposal that would reasonably be expected to lead to an Acquisition Proposal, which notice shall include a summary of the material terms and conditions of, and the identity of the Person making, such Acquisition Proposal, inquiry, proposal or offer, and, if applicable, copies of any such written requests, proposals or offers, including proposed agreements, and thereafter shall keep Parent reasonably informed, on a prompt basis (and in any event within twenty-four (24) hours), of any material developments regarding any Acquisition Proposals or any material change to the terms and status of any such Acquisition Proposal or the material aspects of any bid process established by the Company to review such proposals or offers. The Company agrees that neither it nor any of its subsidiaries shall terminate, waive, or amend to similar effect any existing standstill or similar agreement to which it or one of its subsidiaries is a party, except to the extent that prior to, but not after, obtaining the affirmative vote (in person or by proxy) of the holders of a majority of all of the outstanding shares of Company Common Stock entitled to vote thereon at the Second Stockholders Meeting, or any adjournment or postponement thereof, to adopt this Agreement (the “Second Company Requisite Vote”), after consultation with outside legal counsel, the Company Board determines that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law.

(b) Notwithstanding anything to the contrary in this Agreement, nothing contained herein shall prevent the Company or the Company Board from:

(i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act (or any similar communication to stockholders in connection with the making or amendment of a tender offer or exchange offer, in each case, to the extent legally required) or from making any other disclosure to stockholders if the Company Board determines in good faith that the failure to make such disclosure would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law (provided that neither the Company nor the Company Board may effect a Change of Second Recommendation unless expressly permitted by Section 6.19(c) or Section 6.21, and provided, further, that any such disclosure that has the substantive effect of withdrawing or adversely modifying the recommendation that the stockholders of the Company vote in favor of the adoption of this Agreement and the Merger (the “Second Recommendation”) shall be deemed to be a Change of Second Recommendation); provided, further, that the issuance by the Company or the Company Board of a “stop, look and listen” communication as

4

contemplated by Rule 14d-9(f) promulgated under the Exchange Act (or any similar communication to its stockholders) in which the Company has not indicated that the Company Board has changed the Second Recommendation shall not constitute a Change of Second Recommendation;

(ii) prior to, but not after, obtaining the Second Company Requisite Vote, providing access to its properties, books and records and providing any confidential or non-public information or data in response to a request therefor by a Person or group who has made a bona fide Acquisition Proposal after the date of the Amendment and was not initiated, solicited, encouraged or facilitated in, and did not otherwise result from a, material violation of this Section 6.19, if the Company Board (A) shall have determined in good faith, after consultation with its outside legal counsel and financial advisor, that such Acquisition Proposal constitutes or could reasonably be expected to lead to a Superior Proposal and (B) has received from the Person so requesting such information an executed Acceptable Confidentiality Agreement; provided that any such access, information or data has previously been provided to Parent or its Representatives or is provided to Parent prior to or substantially concurrently with the time such access, information or data is provided to such Person or group;

(iii) prior to, but not after, obtaining the Second Company Requisite Vote, engaging in any negotiations or discussions with any Person and its Representatives who has made a bona fide Acquisition Proposal after the date of the Amendment and was not initiated, solicited, encouraged or facilitated in, and did not otherwise result from a, material violation of this Section 6.19, if the Company Board shall have determined in good faith, after consultation with its outside legal counsel and financial advisor, that such Acquisition Proposal constitutes or could reasonably be expected to lead to a Superior Proposal; or

(iv) prior to, but not after, obtaining the Second Company Requisite Vote, making a Change of Second Recommendation (but only if permitted by Section 6.19(c) or Section 6.21).

(c) Notwithstanding anything in this Agreement to the contrary, if, at any time prior to, but not after, obtaining the Second Company Requisite Vote, the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel, in response to a bona fide Acquisition Proposal that was made after the date of the Amendment and was not initiated, solicited, encouraged or facilitated in, and did not otherwise result from a, material violation of this Section 6.19, that (A) such Acquisition Proposal constitutes a Superior Proposal taking into account any adjustment to the terms and conditions of this Agreement proposed by Parent and Merger Sub in response to such Acquisition Proposal and (B) the failure to take the action in (i) and/or (ii) below would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law, the Company or the Company Board may (and may resolve or agree to) (i) terminate this Agreement under Section 8.1(d)(ii) and enter into a definitive merger agreement, acquisition agreement or similar written agreement with respect to such Superior Proposal and/or (ii) effect a Change of Second Recommendation in accordance with clause (x)(A) of Section 6.21; provided, however, that, if the Company terminates the Agreement pursuant to Section 8.1(d)(ii), the Company pays to Parent the

5

Company Termination Fee required to be paid under Section 8.2(b)(i) concurrently with or prior to such termination; provided, further, that the Company will not be entitled to enter into such Alternative Acquisition Agreement and terminate this Agreement or effect a Change of Second Recommendation pursuant to clause (x)(A) of Section 6.21 unless (x) the Company delivers to Parent a Company Notice, advising Parent that the Company Board proposes to take such action and containing the material terms and conditions of the Superior Proposal that is the basis of the proposed action by the Company Board (including the identity of the party making such Superior Proposal and copies of any written proposals or offers, including proposed agreements) and (y) at or after the expiration of the Notice Period, the Company Board reaffirms in good faith (after consultation with its outside legal counsel and financial advisor and taking into account any adjustment to the terms and conditions of this Agreement proposed by Parent during the Notice Period) that such Acquisition Proposal continues to constitute a Superior Proposal and that the failure to take such action would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law. If requested by Parent, the Company will, and will cause its Representatives to, during the Notice Period, engage in good faith negotiations with Parent and its Representatives regarding any adjustments in the terms and conditions of this Agreement proposed by Parent so that such Acquisition Proposal would cease to constitute a Superior Proposal. The Company agrees to notify Parent promptly if it determines during such Notice Period not to terminate this Agreement and enter into the Alternative Acquisition Agreement referred to in the Company Notice. Any amendment to the financial terms or any other material amendment to the terms and conditions of a proposed Alternative Acquisition Agreement relating to a Superior Proposal will be deemed to be a new proposal or proposed Alternative Acquisition Agreement relating to a Superior Proposal for purposes of this Section 6.19(c) requiring a new Company Notice and an additional Notice Period; provided, however, that such additional Notice Period shall expire at 11:59 p.m., New York City time, on the second (2nd) Business Day immediately following the day on which the Company delivers such new Company Notice (it being understood and agreed that in no event shall any such additional two (2) Business Day Notice Period be deemed to shorten the initial four (4) Business Day Notice Period).

SECTION 6.20 Second Proxy Statement. The Company shall prepare and file with the SEC, as promptly as practicable after the date of the Amendment, a preliminary proxy statement to be sent to the stockholders of the Company in connection with the Second Stockholders Meeting (such proxy statement, as amended or supplemented, the “Second Proxy Statement”). Parent, Merger Sub and the Company will cooperate and consult with each other in the preparation of the Second Proxy Statement and any amendments or supplements thereto. Without limiting the generality of the foregoing, each of Parent and Merger Sub will furnish to the Company the information relating to it as required by the Exchange Act and the rules and regulations promulgated thereunder to be set forth in the Second Proxy Statement and provide such other assistance as may be reasonably requested by the Company. The Company shall use its reasonable best efforts to resolve all SEC comments, if any, with respect to the Second Proxy Statement as promptly as practicable after receipt thereof. The Company shall use its reasonable best efforts to cause the Second Proxy Statement at the date that it (and any amendment or supplement thereto) is first published, sent or given to the stockholders of the Company and at the time of the Second Stockholders Meeting, to comply as to form in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder and shall promptly notify Parent and Merger Sub of the receipt of any comments from the SEC with

6

respect to the Second Proxy Statement and any request by the SEC for any amendment to the Second Proxy Statement or for additional information. If at any time prior to the Second Stockholders Meeting any information relating to Parent or the Company, or any of their respective Affiliates, officers or directors, should be discovered by Parent or the Company, which should be set forth in an amendment or supplement to the Second Proxy Statement so that the Second Proxy Statement would not include any misstatement of a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party which discovers such information shall promptly notify the other Party and, to the extent required by applicable Law, the Company shall promptly file with the SEC and disseminate to the stockholders of the Company an appropriate amendment or supplement describing such information. Prior to filing or mailing the Second Proxy Statement (or any amendment or supplement thereto, other than in connection with a Change of Second Recommendation made in compliance with this Agreement), or responding to any comments of the SEC or its staff with respect thereto, the Company shall provide Parent a reasonable opportunity to review and to propose comments on such document or response and consider in good faith such comments proposed by Parent for inclusion therein.

SECTION 6.21 Second Stockholders Meeting. The Company, acting through the Company Board (or a committee thereof), shall as promptly as practicable following confirmation by the SEC that the SEC has no further comments on the Second Proxy Statement, take all action necessary, including under the DGCL, to duly call, give notice of, convene and hold a meeting of its stockholders for the purpose of approving and adopting this Agreement (including any adjournment or postponement thereof, the “Second Stockholders Meeting”) and shall not, without the prior written consent of Parent, postpone, recess or adjourn such meeting; provided that the Company may postpone, recess or adjourn such meeting (i) if on the date on which the Second Stockholders Meeting is originally scheduled (as set forth in the Second Proxy Statement), the Company has not received proxies representing a sufficient number of Company Shares to obtain the Second Company Requisite Vote or there are insufficient Company Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Second Stockholders Meeting; or (ii) if the failure to postpone, recess or adjourn the Second Stockholders Meeting would reasonably be expected to be a violation of applicable Law for the distribution of any required amendment or supplement to the Second Proxy Statement to be timely provided to the holders of Company Shares; provided that the Second Stockholders Meeting shall not be postponed, recessed or adjourned pursuant to this proviso to a date that is more than thirty (30) days after the date on which the Second Stockholders Meeting was originally scheduled without the prior written consent of Parent. The Company shall (a) subject to Section 6.19(c), include in the Second Proxy Statement the Second Recommendation and (b) subject to Section 6.19(c), use its reasonable best efforts to obtain the Second Company Requisite Vote, including to actively solicit (or cause to be solicited) proxies necessary to obtain the Second Company Requisite Vote; provided that the Company Board may (i) fail to include the Second Recommendation in the Second Proxy Statement distributed to stockholders; (ii) approve, endorse or recommend, or propose publicly to approve, endorse or recommend, or otherwise declare advisable to the stockholders of the Company, an Acquisition Proposal; (iii) following the commencement of a tender offer or exchange offer that constitutes an Acquisition Proposal, fail to publish, send or give to its stockholders, pursuant to Rule 14e-2 under the Exchange Act, within the ten (10) Business Day period (as specified in Rule 14e-2 under the Exchange Act) after such tender offer or exchange offer is first published, sent or given, or

7

subsequently amended in any material respect, a statement recommending that stockholders reject such tender offer or exchange offer and affirming the Second Recommendation; or (iv) formally resolve to effect or publicly announce an intention to effect any of the foregoing, in each case prior to obtaining the Second Company Requisite Vote (a “Change of Second Recommendation”), if (x)(A) a bona fide Acquisition Proposal that was made after the date of the Amendment and was not initiated, solicited, encouraged or facilitated in, and did not otherwise result from a, material violation of Section 6.19 is made to the Company and is not withdrawn and the Company Board determines in good faith, after consultation with its financial advisor and outside legal counsel that such Acquisition Proposal constitutes a Superior Proposal or (B) there exists any event, development, circumstance, change, effect, condition or occurrence (other than an Acquisition Proposal) that was not known by the Company Board or, if known, the consequences of which were not known or reasonably foreseeable, as of the date of the Amendment, (y) the Company Board shall have determined in good faith, after consultation with its outside legal counsel, that the failure of the Company Board to effect a Change of Second Recommendation would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law and (z) (A) if such Change of Second Recommendation is made in response to an Acquisition Proposal, the Company complies with the provisions of Section 6.19(c) or (B) if such Change of Second Recommendation is not made in response to an Acquisition Proposal, the Company (x) delivers to Parent a written notice informing Parent that the Company Board proposes to take such action and the basis of the proposed action no less than four (4) Business Days before taking such action and (y) during such four (4) Business Day period, if requested by Parent, engages in good faith negotiations with Parent and its Representatives regarding any adjustments in the terms and conditions of this Agreement proposed by Parent so that such event, development, circumstance, change, effect, condition or occurrence would cease to warrant a Change of Second Recommendation. The Company shall keep Parent updated with respect to proxy solicitation results as reasonably requested by Parent. Notwithstanding anything to the contrary contained in this Agreement, if subsequent to the date of the Amendment the Company Board makes a Change of Second Recommendation, the Company nevertheless shall submit this Agreement to the holders of Company Shares for approval and adoption at the Second Stockholders Meeting unless and until this Agreement is terminated in accordance with its terms.”
