No failure on the part of Azur to exercise any power, right, privilege or remedy under this Voting Agreement, and no delay on the part of Azur in exercising any power, right, privilege or remedy under this Voting Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. Azur shall not be deemed to have waived any claim available to Azur arising out of this Voting Agreement, or any power, right, privilege or remedy of Azur under this Voting Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of Azur; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

5.16 Independence of Obligations. The covenants and obligations of Stockholder set forth in this Voting Agreement shall be construed as independent of any other contract between Stockholder, on the one hand, and the Company or Azur, on the other. The existence of any claim or cause of action by Stockholder against the Company or Azur shall not constitute a defense to the enforcement of any of such covenants or obligations against Stockholder. Nothing in this Voting Agreement shall limit any of the rights or remedies of Azur under the Merger Agreement, or any of the rights or remedies of Azur or any of the obligations of Stockholder under any agreement between Stockholder and Azur or any certificate or instrument executed by Stockholder in favor of Azur; and nothing in the Merger Agreement or in any other such agreement, certificate or instrument, shall limit any of the rights or remedies of Azur or any of the obligations of Stockholder under this Voting Agreement.

5.17 Other Capacities. Notwithstanding any provision of this Voting Agreement to the contrary, nothing in this Voting Agreement shall limit or restrict Stockholder from acting in good faith in Stockholder’s capacity as a director or officer of the Company (it being understood that this Voting Agreement shall apply to Stockholder solely in Stockholder’s capacity as a stockholder of the Company).
