Re:  Summa Metals Corporation Escrow Agreement


Acceptance Fee                                                        $1,500

Annual Administration Fee                                             $1,500

Out-of-pocket Expenses: 
     Expenses for extraordinary  services,  such as, but not limited to, travel,
     legal,  securities delivery,  and legal notice publication,  will be billed
     additionally.

Extraordinary Time Charges                     $200 per hour (see below)

Additional  Terms and Conditions:  
     Acceptance of the  appointment is subject to terms of the  transaction  and
     document provisions being satisfactory to the bank.

     The fees quoted in this letter apply to services ordinarily rendered in the
     administration  of an  Agency  Account.  They are  subject  to  reasonable
     adjustment  based on final review of  documents.  Fees can also be adjusted
     when  the   Agent  is  called   upon  to   undertake   unusual   duties  or
     responsibilities,  or as changes in law,  procedures,  or the cost of doing
     business  demand.  Services  in  addition  to and not  contemplated  in the
     agreement,  including but not limited to document amendments and revisions,
     non-standard cash and/or investment  transactions,  calculations,  notices,
     reports,  and default  administration  will be billed as Extraordinary Time
     Charges.

     Disbursements  under the document require 72 hours preparation;  exceptions
     from this  policy  may  result in the  application  of  Extraordinary  Time
     Charges.

     Unless otherwise indicated, the above fees provide for the establishment of
     one account.  Additional sub-accounts governed by the same escrow agreement
     may be established at an additional charge of $250 per account.

     The Acceptance Fee and the first year Annual  Administration Fee is payable
     upon execution of the escrow documents.  Annual Administration fees cover a
     full year in advance,  or any part  thereof,  and thus are not pro-rated in
     the year of termination.

     In  determining   the  general   schedule  of  fees,   BankOne  takes  into
     consideration  the  various  incidental  benefits  accruing  to it from the
     operation  of the  accounts.  Collected  funds must be on deposit  prior to
     disbursement  of  payments.  In  addition,  BankOne  has the  use of  funds
     transferred  to pay checks that have not yet been  presented for payment by
     the payee. No interest shall be paid to the client on these funds, it being
     understood  that the float on these funds is considered in the  calculation
     of our fees.
