Crestview, on behalf of itself and its Representatives and Affiliates, hereby irrevocably waives any Released Claims that Crestview or its Representatives or Affiliates may have against the Trust Account now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company or its Representatives or Affiliates and will not seek recourse against the Trust Account for any reason whatsoever (including for an alleged breach of any agreement with the Company or its Affiliates). Crestview agrees and acknowledges that such irrevocable waiver is material to this Subscription Agreement and specifically relied upon by the Company and its Affiliates to induce the Company to enter in this Subscription Agreement, and Crestview further intends and understands such waiver to be valid, binding and enforceable against Crestview and each of its Representatives and Affiliates under applicable law. To the extent Crestview or any of its Representatives or Affiliates commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to the Company or its Representatives or Affiliates, which proceeding seeks, in whole or in part, monetary relief against the Company or its Representatives or Affiliates, Crestview hereby acknowledges and agrees that Crestview’s and its Representatives’ and Affiliates’ sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit Crestview or its Representatives of Affiliates (or any person claiming on any of their behalves or in lieu of any of them) to have any claim against the Trust Account or any amounts contained therein.
