      expiration of the Term of this Agreement. The Consultant shall receive interest
      on a monthly basis on any amount of deferred and accrued Retainer hereunder
      at
      an annual percentage rate of ten percent (12%).

     

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    
      	
            	
              3.

            	
              As
                of the date hereof, Section 15(g) shall be added to read as

      regarding the Consultant’s interpretation of or determinations under this
      Agreement, or any actual, threatened or contemplated litigation or legal,
      administrative or other proceeding involving any provision of this Agreement,
      the Corporation shall pay the Consultant for all legal fees, court costs, fees
      of experts and other costs expenses when reasonably incurred by the Consultant
      in connection with such contest or dispute. Such reimbursement shall be made
      as
      soon as practicable following their submission to the Corporation to the extent
      the Corporation receives reasonable written evidence of such fees and expenses.
