“Cooperation with Regulatory Approvals. Parent and the Company each will, and Parent and the Company will cause each of their respective Affiliates to, use reasonable best efforts to comply as promptly as practicable with all legal requirements which may be imposed on it under any applicable Antitrust Laws in connection with the transactions contemplated by this Agreement. Without limiting the generality of the preceding sentence, each of Parent and the Company shall cause each of their respective Affiliates to, as soon as practicable, submit applicable notification and report forms under the HSR Act within thirty (30) Business Days from the date of this Agreement, if such filing is required pursuant to the HSR Act and applicable regulations, and make any other appropriate filings with any Governmental Authority in connection with the transactions contemplated by this Agreement. Each of Parent and the Company will promptly and in good faith respond to all information requested of it by the U.S. Federal Trade Commission, U.S. Department of Justice, or any other Authority in connection with such notification and otherwise cooperate in good faith with each other and such Authorities. Each party will promptly furnish to the other such information and assistance as the other may reasonably request in connection with its preparation of any filing or submission that is necessary under the HSR Act and any other applicable Antitrust Laws and will use reasonable best efforts to cause the expiration or termination of the applicable waiting periods as soon as practicable, including, if appropriate, by requesting early termination of the HSR waiting period. Parent and the Company agree not to, and Parent and the Company agree to cause each of its Affiliates not to, extend any waiting period under the HSR Act and other applicable Antitrust Laws or enter into any agreement with any Governmental Authority to delay, or otherwise not to consummate as soon as practicable, any of the Transactions contemplated by this Agreement except with the prior written consent of the non-requesting party, which consent may be withheld in the sole discretion of the non-requesting party. Neither Parent nor the Company shall, and each shall use its reasonable best efforts to cause their respective Affiliates not to, directly or indirectly take any action, including, directly or indirectly, acquiring or investing in any Person or acquiring, leasing or licensing any assets, or agreement to do any of the foregoing, if doing so would reasonably be expected to impose any material delay in the obtaining of, or significantly increase the risk of not obtaining, any required approval under the HSR Act and any applicable Antitrust Laws. Without limiting the foregoing, Parent and the Company shall: (i) promptly inform the other of any communication to or from the U.S. Federal Trade Commission, the U.S. Department of Justice or any other Authority with respect to Antitrust Laws regarding the transactions contemplated by this Agreement; (ii) permit each other to review reasonably in advance any proposed substantive written communication to any such Authority and incorporate reasonable comments thereto; (iii) give the other prompt written notice of the commencement of any Action with respect to such transactions under Antitrust Laws; (iv) not agree to participate in any substantive meeting or discussion with any such Authority in respect of any filing, investigation or inquiry concerning this Agreement or the transactions contemplated by this Agreement with respect to Antitrust Laws unless, to the extent reasonably practicable, it consults with the other party in advance and, to the extent permitted by such Authority, gives the other party the opportunity to attend; (v) keep the other reasonably informed as to the status of any such Action; and (vi) promptly furnish each other with copies of all correspondence, filings (except for filings made under the HSR Act) and written communications (and memoranda setting forth the substance of all substantive oral communications) between such party and, and in the case of Parent, its Subsidiaries (if applicable) and their respective Representatives and advisors, on one hand, and any such Authority, on the other hand, in each case, with respect to this Agreement and the transactions contemplated by this Agreement with respect to Antitrust Laws; provided that materials required to be supplied pursuant to this section may be redacted (1) to remove references concerning the valuation of the Company, (2) as necessary to comply with contractual arrangements, (3) as necessary to comply with applicable Law, and (4) as necessary to address reasonable privilege or confidentiality concerns; provided further, that a party may reasonably designate any competitively sensitive material provided to another party under this Section 0 as “Outside Counsel Only”.”

(b) Section 8.9(a)(ii) of the Original Merger Agreement is hereby amended and restated to read in its entirety as follows:

“(ii) provide that Parent shall extend the Initial Extension Date up to six (6) times by an additional one month each time (for a total of up to 24 months to complete an initial business combination), unless the Closing shall have occurred, upon five days’ advance notice prior to the applicable deadline (the “Extension Proposal”).”

(c) Section 8.9(f) of the Original Merger Agreement is hereby amended and restated to read in its entirety as follows:

“(f) If the Extension Proposal is approved, Parent shall pay any additional amount or amounts into the Trust Account (such amount, the “Extension Fee”) at the time the Extension Proposal is approved and, following the Initial Extension Date, on a monthly basis until the earlier of the date that is six months following the Initial Extension Date or Agreement is terminated pursuant to Article X. Parent shall deliver an extension letter to the Trustee, notifying the Trustee of the approval of such Extension Proposal, signed on behalf of Parent by an executive officer of Parent, and (b) Parent shall deliver the aggregate amount necessary by wire transfer of immediately available funds to the Trustee, for deposit in the Trust Account in accordance with the extension letter and the Trust Agreement.”
