7.3 Acquisition Proposals; Change of Recommendation. <omitted> (d) No Change of Recommendation. <omitted> 
(ii) Notwithstanding anything to the contrary set forth in this Section 7.3, prior to the time the Requisite Company Vote is obtained, the Company Board may (A) effect a Change of Recommendation if (x)(1) a written Acquisition Proposal that the Company Board determines in good faith (after consultation with outside legal counsel) is bona fide and that did not arise from or in connection with a breach of the obligations set forth in this Section 7.3 is received by the Company after the date of this Agreement and is not withdrawn prior to the Change of Recommendation, and the Company Board determines in good faith, after consultation with outside legal counsel and a financial advisor of nationally recognized reputation, that such Acquisition Proposal constitutes a Superior Proposal or (2) an Intervening Event has occurred, and (y) the Company Board determines in good faith, after consultation with outside legal counsel and a financial advisor of nationally recognized reputation, that failure to effect a Change of Recommendation would reasonably be likely to be in violation of the directors’ fiduciary duties under applicable Law or (B) take action to terminate this Agreement pursuant to, and in accordance with, Section 9.3(b) to enter into an Alternative Acquisition Agreement with respect to a written Acquisition Proposal that the Company Board determines in good faith (after consultation with outside legal counsel) is bona fide and that did not arise from or in connection with a breach of the obligations set forth in this Section 7.3 and that the Company Board determines in good faith, after consultation with outside legal counsel and a financial advisor of nationally recognized reputation, that (1) such Acquisition Proposal constitutes a Superior Proposal and (2) failure to effect a Change of Recommendation would reasonably be likely to be in violation of the directors’ fiduciary duties under applicable Law; provided, however, that a Change of Recommendation or action to terminate this Agreement pursuant to Section 9.3(b) may not be made (i) unless the Company shall have complied in all material respects with its obligations under this Section 7.3 and (ii) unless and until the Company has given Parent written notice of such action four calendar days in advance (an “Initial Notice”), setting forth in writing that the Company Board intends to consider whether to take such action, the reasons with respect thereto and (I) in the case of a Superior Proposal, the material terms and conditions of such Superior Proposal and (II) in the case of an Intervening Event, a reasonable description of such Intervening Event (it being agreed that, in each case, the delivery of such notice by the Company shall not constitute a Change of Recommendation). After giving such Initial Notice and prior to effecting such Change of Recommendation or taking such action to terminate the Agreement pursuant to Section 9.3(b), the Company shall, and shall instruct its legal and financial advisors to, negotiate in good faith with Parent and its Representatives throughout such four (4) calendar days required to comply with Day period (to the extent Parent wishes to negotiate) to make such revisions to the terms of this Agreement such that the failure of the Company Board to effect a Change of Recommendation or to take such action to terminate this Agreement pursuant to Section 9.3(b) would no longer be reasonably be likely to be in violation of its fiduciary duties. At the end of the four (4) calendar day period, prior to taking action to effect a Change of Recommendation or taking action to terminate the Agreement pursuant to Section 9.3(b), the Company Board shall take into account any changes to the terms of this Agreement proposed by Parent in writing and any other information offered by Parent in writing in response to the Initial Notice, and shall have determined in good faith (after consultation with outside legal counsel) that (A) in the case of a Superior Proposal, the Superior Proposal continues to constitute a Superior Proposal, and (B) in the case of an Intervening Event, the failure to effect a Change of Recommendation in response to such Intervening Event would be in violation of the directors’ fiduciary duties under applicable Law, in each case, if such changes offered in writing were to be given effect. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 7.3(d) except that the obligation to give advance written notice with respect thereto as set forth in this Section 7.3(d) shall be reduced to three (3) calendar days.
