(e) by the Company with respect to a particular Investor upon a breach of any representation, warranty, covenant or agreement on the part of such Investor set forth in this Agreement, or if any representation or warranty of such Investor shall have become untrue, such that the conditions set forth in Section 5.2(a) could not be satisfied by the date specified in paragraph (b) above;

This Agreement may not be amended or modified except by an instrument in writing signed by the Company and each of the Investors.

8.2 Survival of Representations, Warranties and Covenants, Assignability of Rights. All representations and warranties made herein and in the certificates, exhibits or schedules delivered or furnished in connection herewith shall terminate as of the earlier of (a) the Closing and (b) termination of this Agreement pursuant to Section 7.1. Except as otherwise provided in this Agreement, all covenants, agreements, representations and warranties shall inure to the benefit of the successors and assigns of the parties.

8.3 Governing Law. This Agreement shall be deemed to be a contract made under, and shall be construed in accordance with, the laws of the State of Delaware (without giving effect to principles of conflicts of law the effect of which would cause the application of domestic substantive laws of any other jurisdiction).
