limitations below:  
  

	 	(1)	 the maximum aggregate liability of each of the Seller Parties to the Investor for any indemnification under
this Agreement shall not exceed the aggregate amount equal to one hundred percent (100%) of the Purchase Price actually paid by the Investor. 

  
 31

thereof nor the waiver of any other right, power or remedy available to such Party. Without limiting the foregoing, the Parties hereto acknowledge and agree irreparable harm may occur for which money damages would not be an adequate remedy in the
