          Inspection and notifies Seller of any deficiencies caused by a
          material misrepresentation on the part of Seller then Seller shall
          have the right for thirty (30) days after notice to cure any such
          deficiency. Unless cured by Seller or otherwise waived by Buyer, Buyer
          shall have the right to void this Agreement and receive a full refund
          of the $75,000.00 deposit.
