15. Except as expressly set forth herein, the Loan Documents shall remain in full force and effect, and no amendment in respect of any term or condition of any Loan Document shall be deemed to be an amendment in respect of any other term or condition contained in any Loan Document.

16. This Amendment may be executed in any number of counterparts, each of which shall constitute an original but all of which when taken together shall constitute a single contract. It shall not be necessary in making proof of this Amendment to produce or account for more than one counterpart signed by the party to be charged. Delivery of an electronic counterpart to this Amendment (which may include electronic mail transmission (in printable format) or facsimile of a signed signature page of this Amendment) shall be as effective as delivery of an original counterpart.

17. THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE COMMONWEALTH OF MASSACHUSETTS, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.
