Section 6.4           Acquisition Proposals. <omitted> (d)    <omitted> Notwithstanding the foregoing, at any time prior to the receipt of the Company Stockholder Approval, the Company Board (or any committee thereof) may effect a Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 8.3(a) and enter into a Company Acquisition Agreement, if: (i) the Company notifies Parent, in writing, at least four Business Days (the “Superior Proposal Notice Period”) before making a Company Adverse Recommendation Change or terminating the Agreement pursuant to Section 8.3(a) and entering into a Company Acquisition Agreement, of its intention to take such action with respect to a Superior Proposal (which notice shall not, by itself, constitute a Company Adverse Recommendation Change), which notice shall state expressly that the Company has received an Alternative Proposal that the Company Board (or a committee thereof) has determined in good faith, after consulting with outside legal counsel and its financial advisor, constitutes a Superior Proposal and that the Company Board (or a committee thereof) intends to effect a Company Adverse Recommendation Change; (ii) the Company attaches to such notice the most current version of the proposed agreement reflecting the Superior Proposal and any material documents related thereto, and summarizes in reasonable detail any material terms and conditions of such Superior Proposal that are not reflected in the proposed agreement with respect to such Superior Proposal and the identity of the third party making such Superior Proposal; (iii) during the Superior Proposal Notice Period, the Company negotiates with Parent in good faith, and causes its Representatives to negotiate with Parent in good faith, to make such adjustments in the terms and conditions of this Agreement so that such Alternative Proposal ceases to constitute a Superior Proposal, if Parent, in its discretion, proposes in good faith to make such adjustments (it being agreed that in the event that, after commencement of the Superior Proposal Notice Period, there is any material revision to the terms of a Superior Proposal, including any revision in price, the Superior Proposal Notice Period shall be extended, if applicable, to ensure that at least three Business Days remain in the Superior Proposal Notice Period subsequent to the time the Company notifies Parent of any such material revision); and (iv) the Company Board (or a committee thereof) determines in good faith, after consulting with outside legal counsel and its financial advisor, that such Alternative Proposal continues to constitute a Superior Proposal after taking into account any adjustments made by Parent during the Superior Proposal Notice Period to the terms and conditions of this Agreement.

Section 6.4           Acquisition Proposals. <omitted> (e)          Notwithstanding anything to the contrary in Section 6.4(a)-(d), but subject to Section 6.4 and the last sentence of this Section 6.4(e), prior to the receipt of the Company Stockholder Approval, the Company Board (or a committee thereof) may effect a Company Adverse Recommendation Change if : (i) an Intervening Event occurs, (ii) the Company Board (or such committee) determines in good faith, after consulting with outside legal counsel and its financial advisor that the failure to effect such Company Adverse Recommendation Change would breach its fiduciary duties under applicable Law, (iii) prior to effecting the Company Adverse Recommendation Change, the Company promptly notifies Parent, in writing, at least two Business Days (the “Company Adverse Recommendation Notice Period”) before taking such action of the Company Board’s (or such committee’s) intent to consider such action (which notice shall not, by itself, constitute a Company Adverse Recommendation Change), and which notice shall include a reasonably detailed description of the underlying facts giving rise to the Intervening Event, and the reasons the Company Board (or such committee) proposes to take such action; (iv) the Company shall, and shall cause its Representatives to, during the Company Adverse Recommendation Notice Period, negotiate with Parent in good faith to make such adjustments in the terms and conditions of this Agreement so that the underlying facts giving rise to the Intervening Event, and the reasons the Company Board (or such committee) proposes to take such action, cease to constitute circumstances causing the Company Board to propose making a Company Adverse Recommendation Change, if Parent, in its discretion, proposes in good faith to make such adjustments; and (v) the Company Board (or such committee) determines in good faith, after consulting with outside legal counsel and its financial advisor and taking into account any adjustments made by Parent during the Company Adverse Recommendation Notice Period, that the failure to effect such Company Adverse Recommendation Change would breach its fiduciary duties under applicable Law. The Company acknowledges and hereby agrees that any Company Adverse Recommendation Change effected (or proposed to be effected) in response to or in connection with any Alternative Proposal may be made solely and exclusively pursuant to Section 6.4(d) only, and may not be made pursuant to this Section 6.4(e), and any Company Adverse Recommendation Change may only be made pursuant to this Section 6.4 and no other provisions of this Agreement. For purposes of this Agreement, an “Intervening Event” means any event, change, effect, development or occurrence, or any consequence thereof, that becomes known to the Company Board after the date of this Agreement that (i) was not known, (or if known, the consequences of which were not reasonably foreseeable), to the Company Board as of or prior to the date of this Agreement and did not result from a breach of this Agreement by the Company and (ii) does not relate to or involve an Alternative Proposal.
