          1)   The Bidders shall list subcontractors which will provide

          State of Nevada, as required by law.

6.   That if the Bidder does not provide the above submittals on or before the
     7th calendar day, or does not keep the bonds or insurance policies in
     effect or allows them to lapse, the Bidder will pay over to the Owner the
     amount of $2,500 per day as liquidated damages.

7.   That this Proposal is genuine and is not sham or collusive, or made in the
     interest of, or on behalf of any person not herein named, nor the Bidder in

     bidder.

8.   The Bidder further proposes and agrees that if his bid is accepted they
