Section 6.4    No Solicitation by the Company and Company Change in Recommendation <omitted> (d)        Notwithstanding anything  to  the  contrary  contained  in  this Agreement,  at  any  time  prior to  the  receipt  of  the  Company Stockholder Approval,  the  Company  Board, upon  the  recommendation  of  the  Special  Committee,  may  make  a  Company Change in Recommendation in response to a Company Intervening Event if  <omitted> (ii) (A) the Company shall have provided Parent with at least four (4) Business Days written notice prior to making any such Company Change in Recommendation, which notice shall describe the Company Intervening Event in reasonable detail and which notice shall not itself constitute a Company Change in Recommendation and (B) if requested by Parent in good faith, during such four (4) Business Day period after providing such notice, negotiate in good faith with respect to any revisions to the terms of this Agreement proposed by Parent so that a Company Change in Recommendation would no longer be necessary and (iii) after giving effect to the revisions contemplated by the foregoing clause (ii) if any, after consultation with financial advisors and outside counsel, the Company Board, upon the recommendation of the Special Committee, shall have determined in good faith that failure to make the Company Change in Recommendation in response to such Company Intervening Event, would reasonably be expected to be inconsistent with the Company Board’s fiduciary duties under applicable Law. For the avoidance of doubt, the provisions of this Section 6.4(d) shall also apply to any material change in the event, occurrence or fact relating to such Company Intervening Event and require a new notice from the Company pursuant to Section 6.4(d), except that the references to four (4) Business Days in this Section 6.4(d) shall be deemed to be two (2) Business Days.

Section 6.4    No Solicitation by the Company and Company Change in Recommendation <omitted> (f)    Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be entitled to make a Company Change in Recommendation pursuant to Section 6.4(e) or terminate this Agreement pursuant to Section 8.1(h) unless (x) the Company shall have provided to Parent four (4) Business Days prior written notice (the “Company Superior Proposal Notice”), which notice shall not constitute a Company Change in Recommendation, advising Parent that the Company intends to take such action (and the material terms and conditions of any such Company Superior Proposal), the identity of the Person making such Company Acquisition Proposal and copies of all definitive or proposed agreements or other material documents submitted in connection therewith and (y):   ( i )     during the four (4) Business Day period, if requested in writing by Parent in good faith, the Company and its Representatives shall have engaged in good faith negotiations with Parent regarding changes to the terms of this Agreement intended by Parent to cause such Company Acquisition Proposal to no longer constitute a Company Superior Proposal; and   (ii)    the Company Board shall have considered any adjustments to this Agreement that may be proposed in writing by Parent (the “Parent Proposed Changed Terms”) no later than 11:59 p.m., New York City time, on the fourth (4th) Business Day of such four (4) Business Day period and, upon the recommendation of the Special Committee, shall have determined in good faith (after consultation with its financial advisors and outside counsel) that the Company Superior Proposal would continue to constitute a Company Superior Proposal if such Parent Proposed Changed Terms were to be given effect, and that the failure to make the Company Change in Recommendation or terminate this Agreement pursuant to Section 8.1(h) would reasonably be expected to be inconsistent with the fiduciary obligations of the Company Board under applicable Law.   For the avoidance of doubt, any (1) material revisions to the terms of a Company Superior Proposal or (2) material revisions to a Company Acquisition Proposal that the Company Board had determined no longer constitutes a Company Superior Proposal, shall constitute a new Company Acquisition Proposal and shall in each case require the Company to deliver to Parent a new Company Superior Proposal Notice, except that the references to four (4) Business Days in this Section 6.4(f) shall be deemed to be two (2) Business Days.
