From and after the date hereof, each reference in the Securities Purchase Agreement to “this Agreement” or words of like import shall mean and be a reference to the Agreement (as defined in the Securities Purchase Agreement) as amended by this letter agreement and each reference in the Securities Purchase Agreement to “this Securities Purchase Agreement” or words of like import shall mean and be a reference to the Securities Purchase Agreement as amended by this letter agreement.

This letter agreement will be governed by and construed in accordance with the federal law of the United States if and to the extent such law is applicable, and otherwise in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State.
