Section 6.1. Acquisition Proposals. <omitted> provided, further, that the Company will not be entitled to effect such Change of Recommendation or terminate this Agreement in accordance with Section 8.1(d)(ii) unless (x) the Company delivers to Parent a written notice (a “Company Notice”), at least four calendar days before the Board of Directors (or a duly authorized committee thereof) takes such action, advising Parent that the Board of Directors (or a duly authorized committee thereof) proposes to take such action and containing the material details of such Intervening Event or the material terms and conditions of the Superior Proposal (and shall have provided to Parent a copy of the available proposed transaction agreement to be entered into in respect of such Superior Proposal), as applicable, that is the basis of the proposed action of the Board of Directors (or a duly authorized committee thereof) and (y) at or after 5:00 p.m., New York City time, on the fourth (4t h) calendar day immediately following the day on which the Company delivered the Company Notice (such period from the time the Company Notice is provided until 5:00 p.m. New York City time on the fourth (4t h) calendar day immediately following the day on which the Company delivered the Company Notice, the “Notice Period”), the Board of Directors (or a duly authorized committee thereof) shall have determined in good faith (after consultation with its outside counsel and financial advisors and taking into account any changes to the terms of this Agreement agreed to in writing by Parent during the Notice Period) that the failure to make a Change of Recommendation or to terminate this Agreement pursuant to Section 8.1(d)(ii) would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, or in the case of an Acquisition Proposal, such Acquisition Proposal continues to constitute a Superior Proposal; provided, however, that any amendment to the financial terms or other material terms or conditions (including the provision of financing) of such Acquisition Proposal (which, after taking into account any changes offered and agreed to in writing by Parent during the Notice Period, ceased to constitute a Superior Proposal) that would reasonably be likely to result in such Acquisition Proposal again constituting a Superior Proposal, shall require a new Company Notice and an additional two (2) Business Day Notice Period. If requested by Parent, the Company will, and will cause its Subsidiaries and direct its or their Representatives to, during the Notice Period, engage in good faith negotiations with Parent and its Representatives to make such adjustments to the terms and conditions of this Agreement so that, (A) in the case of an Acquisition Proposal, such Acquisition Proposal would cease to constitute a Superior Proposal, and (B) in the case of an Intervening Event, the failure of the Board of Directors (or a duly authorized committee thereof) to make a Change of Recommendation would not be reasonably likely to be inconsistent with its fiduciary duties under applicable Law.
