        accordance with Section 1.3(c).

        (c) Escrow for Subsequent Installments. At the Closing, Purchaser shall
            -----------------------------------
        deposit with McGrigor Donald, as Escrow Agent, pursuant to the terms of
        a mutually agreeable Escrow Agreement among Purchaser, Seller and Escrow
        Agent (the "Escrow Agreement"), the amount of (Pounds)606,666 (the

        amount shall be satisfied to the extent possible by, at the discretion
        of Purchaser, a reduction in subsequent Earn-Out Payment(s).

        6. Except as set forth in this Amendment, the Agreement shall remain
unchanged and in full force and effect.
