1.Definitions; References. Unless otherwise specifically defined herein, each capitalized term used herein but not otherwise defined herein shall have the meaning assigned to such term in the TRA.

2.TRA Acceleration. The Parties agree that the consummation of the transactions contemplated by the Merger Agreement will give rise to a “Change of Control” as defined in the TRA (such Change of Control, the “MA Change of Control”), and that the TRA Holder has elected (a) to waive its right to receive an Early Termination Option Notice, (b) to irrevocably terminate the TRA and (c) to accept payment of the Termination Payment in full satisfaction of all amounts to which it is entitled under the TRA, including, without limitation, the Early Termination Payment and the other amounts it is entitled to receive.
