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