         this Agreement and/or the Deposits. In case of any suit, proceeding,
         cause of action, demand or other claim to which Escrow Holder is or at
         any time may be a party, Indemnitors agree to pay, promptly upon Escrow

         or all of the Deposits, or if any dispute arises between or among
         Depositors and/or any other person or entity relating in any way to any

         this Agreement and such items and filing its complaint in interpleader,
         Escrow Holder shall be relieved of and released from all liability
         under the terms hereof as to the items so deposited. If the Court does
         not provide for reimbursement to Escrow Holder for its attorney fees,
         costs and expenses related to the interpleader action out of the
         interplead funds, then Escrow Holder shall have a claim enforceable by
