other covenant, agreement, representation, warranty or provision herein contained or contained in any Sale Agreement, nor shall any waiver or any custom or practice which may evolve between the parties in the administration of the terms hereof or of any Sale Agreement, be construed to lessen the right of the Purchaser to insist upon the performance by the Seller in strict accordance with said terms.
