Meghji, Suleman E. Lunat, Brian Griffith, Andrew L. Farkas, Osbert Hood, and Philip Marber with respect to certain matters, including with respect to the persons listed on Exhibit A hereto, the transfer of shares of common stock of the Buyer (“Common Stock”) held of record by each of them (as further described on Exhibit A hereto, the “Founder Shares”), and (iii) that certain Waiver, Consent and Agreement to Forfeit Founder Shares, dated March 20, 2018, by and among the parties to the Merger Agreement (the “Waiver Agreement”).

Subsequent to the consummation of the transactions contemplated by the Merger (“Closing”), (i) M III LLC distributed Founder Shares to certain of its members and (ii) the parties hereto have agreed to amend the vesting provisions set forth in the Original Agreement.  This Amended and Restated Founder Shares Amendment Agreement amends and restates the Original Agreement to give effect to the foregoing.

(c)On or prior to the tenth anniversary of the date of this Agreement, all of such holder’s then-unvested Earnout Shares will immediately and irrevocably vest upon the occurrence of any of the following events that results in all of Buyer’s stockholders having the right to exchange their shares of Common Stock for consideration in cash, securities or other property which equals or exceeds $10.00 per share (as adjusted for stock splits, dividends, reorganizations, recapitalizations and the like):

	5.
	If the Earnout Shares have not vested on or prior to the ten-year anniversary of the date of the Merger Agreement, the Earnout Shares shall be forfeited to Buyer without consideration and with no further action required of any Person. Upon any such forfeiture, such Earnout Shares shall transfer to Buyer for cancellation and in exchange for no consideration.




		
	6.
	Prior to the vesting of any Earnout Shares hereunder, the holder of such Earnout Shares shall nevertheless retain the right to vote such Earnout Shares.




		
	7.
	Until all Earnout Shares have vested or been forfeited hereunder, an amount equal to any dividends or distributions that would have been payable to the holders of Earnout Shares if the Earnout Shares had vested prior to the record date for such dividends or distributions shall be withheld by the Buyer for the benefit of the holders of the Earnout Shares (the “Withheld Amount”).  If any securities of the Buyer or any other Person are included in the Withheld Amount, then any dividends or distributions in respect of or in exchange for any of such securities in the Withheld Amount, whether by way of stock splits or otherwise, shall be delivered to the Buyer and included in the “Withheld Amount”, and will be released to the Buyer or the holders of the Earnout Shares, as applicable, upon the release of the corresponding securities.  If and when the Earnout Shares vest in accordance with Section 1, the Buyer shall release to the holders of the Earnout Shares, the aggregate amount of the Withheld 













Amount  attributable to the Earnout Shares that have vested and, if applicable, shall continue to withhold any remaining Withheld Amount that is attributable to the Earnout Shares that have not yet vested until such Earnout Shares vest, in which case such remaining Withheld Amount shall be released to the holders of Earnout Shares. If all or any portion of the Earnout Shares are forfeited to the Buyer in accordance with Section 5, then the portion of the Withheld Amount attributable to the portion of the Earnout Shares that have been forfeited to the Buyer, as applicable, shall be forfeited to Buyer without consideration and with no further action required of any person. 


		
	8.
	This Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof.  This Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.




		
	9.
	No party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of each of the other parties hereto. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Agreement shall be binding on each of the parties hereto and their respective successors and assigns.




		
	10.
	This Agreement shall be construed and enforced in accordance with the internal laws of the State of Delaware without regard to the conflict of laws principles thereof. The parties hereto (a) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Agreement shall be brought and enforced in the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks jurisdiction, then in the applicable Delaware state court), or if under applicable Law exclusive jurisdiction of such action is vested in the federal courts, then the United States District Court for the District of Delaware, and irrevocably submits to such jurisdiction and venue, which jurisdiction and venue shall be exclusive, and (b) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.




		
	11.
	The parties agree that irreparable damage would occur in the event that the parties hereto do not perform the provisions of this Agreement in accordance with its terms or otherwise breach such provisions.  Accordingly, the parties acknowledge and agree that the parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at Law or in equity.  Each of the parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that the other parties have an adequate remedy at Law or an award of specific performance is not an appropriate remedy for any reason at Law or equity.  Any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.




		
	12.
	Any notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing and shall be sent by electronic mail (with recipient receipt acknowledgment), express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or facsimile transmission to Buyer and Seller at the addresses specified 













in the Merger Agreement and to the holders of Founder Shares at the addresses set forth on Exhibit A.


		
	13.
	This Agreement shall immediately terminate, without any further action by the parties hereto, at such time, if any, that the Merger Agreement is terminated in accordance with its terms.
