For and in consideration of SPAC entering into this Agreement and discussions with Consultant regarding the Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Consultant hereby agrees on behalf of itself and its affiliates that, notwithstanding anything to the contrary in this Agreement, neither Consultant nor any of its affiliates does now or shall at any time hereafter have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make any claim against the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result of, in connection with or relating in any way to, this Agreement or any proposed or actual business relationship between SPAC or its representatives, on the one hand, and Consultant or its representatives, on the other hand, or any other matter, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (collectively, the “Released Claims”). Consultant on behalf of itself and its affiliates hereby irrevocably waives any Released Claims that Consultant or any of its affiliates may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with SPAC or its representatives and will not seek recourse against the Trust Account (including any distributions therefrom) for any reason whatsoever (including for an alleged breach of this Agreement or any other agreement with SPAC or its affiliates). Consultant agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by SPAC and its affiliates to induce SPAC to enter into this Agreement, and Consultant further intends and understands such waiver to be valid, binding and enforceable against Consultant and each of its affiliates under applicable law.
