               Contract.

                    reasonable notice to inspect (and copy - at its cost and
                    subject to entering into any agreement reasonably required
                    by the Buyer to preserve the confidential nature of such

               Independent Accountant shall be borne by which of the Buyer or
               the Seller was the person whose calculation was not determined
               the more reasonable by the Independent Accountant.

          (e)  Upon final resolution by the parties of the Net Profit and
               Revenue calculations, the Buyer and Seller shall execute a
               Release Notice in accordance with the Escrow Agreement.
