of $50,000 to $200,000 from November 1, 2002, through March 30, 2003. At its
sole discretion, the Promisee may cease making such advances completely or may
cease for a time and then recommence making such advances. Prior to expenditure,
all loan proceeds made to ATI require the approval of the Promisee and the
signature of one of its authorized officers on ATI checks as a co-signer in this
regard. The Promisee is under no obligation to complete the full loan should it
so chose not to make any further advances. In the event that the Promisee does
not advance the full amount of the loan to ATI as referred to above, ATI is only
obligated to repay that amount actually lent and received by it from the
Promisee and any and all accrued interest regarding that sum.

     In the event the Promisor merges with, or acquires, ATI, the loan and this
note will be extinguished and the loan proceeds that have been advanced to ATI
will be deducted from the other consideration that the Promisee has pledged in
such acquisition 2 or merger or will be credited to it or its shareholders by
the issuance of additional shares of ATI's common stock in the appropriate
amounts.
