Section 5.09 Reasonable Best Efforts. <omitted> (d) Without limiting the generality of Parent’s undertakings pursuant to this  Section 5.09, Parent agrees to use its reasonable best efforts including by promptly taking any and all steps necessary to avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Entity or any other Person so as to enable the parties to consummate the transactions contemplated by this Agreement as promptly as reasonably practicable (and in no event later than the Outside Date), including proposing, negotiating, committing to and effecting, by consent decree, order, hold separate orders, or otherwise the sale, divestiture or disposition of any of its assets, properties or businesses or of the assets, properties or businesses to be acquired by it pursuant to this Agreement as are required to be divested in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other Order in any suit or proceeding, which would otherwise have the effect of materially delaying or preventing the consummation of the transactions contemplated by this Agreement from occurring prior to the Outside Date. In addition, Parent shall use its reasonable best efforts including by defending through Legal Action on the merits any claim asserted in any Governmental Entity by any party in order to avoid entry of, or to have vacated or terminated, any Order (whether temporary, preliminary or permanent) that would prevent the consummation of the Closing from occurring prior to the Outside Date. Notwithstanding anything herein to the contrary, (i) the Company shall not take or agree to take any actions described in this Section 5.09(d) without the prior written approval of Parent and (ii) neither Parent nor the Company shall be required to take or agree to take any action (including any disposition, licensing, holding separate or conduct remedy) or to limit or agree to limit Parent’s freedom of action or that of the Company or of any Subsidiary in any respect unless (x) such agreement, action or limitation would not reasonably be expected to, individually or in the aggregate, result in a Substantial Detriment and (y) the effectiveness of any such agreement, action or limitation is conditioned upon the Closing. “Substantial Detriment” means a material adverse effect on the Company and its Subsidiaries, taken as a whole, Parent, or the pro forma Parent (together with the Company and its Subsidiaries) (but assuming for this purpose that Parent or the pro forma Parent is the size, and has the aggregate financial and operating metrics, of the Company and its Subsidiaries, taken as a whole).
