D.       BILLING

         In consideration of the services rendered by Golden Access, Customer
         shall pay termination fees as outlined in Appendix B which may be
         adjusted from time to time at the discretion of Golden Access and the
         new rate table shall be effective upon 15 days notice, unless interim
         rate changes are necessary to improve Quality of Service.

         In order to secure payment for these services, the Customer agree to
         deposit prior to the performance of any services an amount of
         $2,500.00 to cover one times the estimated average monthly sales
         volume. This deposit shall be either as Cash, Certified Cheque, Bank
         transfer and/or an irrevocable Letter of Credit from a financial
         institution acceptable to Golden Access. Said deposit shall be subject
         to offset by Golden Access in the event payment of the outstanding
         account balance is not made after 7 days from receipt of invoice.
         Golden Access reserves the right to review the deposit from time to
         time and adjust the required amount necessary based upon invoiced
         amounts for previous billing periods.

         A bi-weekly financial settlement will take place between Golden Access
         and the Customer. This settlement will be based upon the CDR (Call
         Detail Records) produced by the Service which indicate the necessary
         accounting information required to calculate the amount due. Golden
         Access will prepare the invoice and a settlement report detailing each
         transaction from the CDRs collected by its Network Control Center.
         Should there be any discrepancies in the call detail reports, the
         items in question shall be deferred to a further review process. These
         discrepancies shall in no way delay the settlement process as a whole
         and will be treated as a separate deficiency to be reconciled within a
         period of 30 days. A 10% discount on the rates in Appendix B will be
         offered to the Customer for the first 3 months of this Agreement,
         after which time, the regular rates will apply unless there is a
         mutual agreement to extend the discount. The discount will be applied
         against the total due for each billing period.

         and shall be extended on an annual basis thereafter unless terminated

This agreement is entered into as of January 12, 2000 between Hertford

agreement (hereinafter "Party") agrees that for the purpose of evaluating a
potential business relationship, the parties will disclose and receive
information under the terms and conditions specified below:

NOW THEREFORE, the parties hereby agree as follows:

1.       All communications or data, in any form, which are disclosed by one
         Party or any of its subsidiary, parent or associate companies
         ("Disclosing Party") to the other Party or any of its subsidiary,
         parent or associate companies ("Receiving Party") and which are to be
         protected hereunder against unrestricted disclosure or competitive use
         by the Receiving Party shall be deemed to be "Confidential
         Information".

2.       All Confidential Information, if in writing or other tangible form,
         shall be labeled as "Confidential" at the time of its delivery, and,
         if oral, shall be identified as "confidential" prior to disclosure.

3.       Confidential Information of the Disclosing Party shall be treated as
         confidential and safeguarded hereunder by the Receiving Party for a
         period of two (2) years from the date of disclosure unless earlier
         waived in writing by the Disclosing Party.

4.       The Receiving Party agrees that (a) any Confidential Information
         disclosed hereunder shall be used by the Receiving Party solely for
         the purpose set forth above and (b) except as may be required by
         applicable law or legal process, the Receiving party will not disclose
         or disseminate such Confidential Information to anyone, except to
         those employees (including employees of its parent, subsidiaries and
         affiliates) and professional advisers who have the need to know such
         Confidential Information for the purpose for which it is disclosed,
         unless and until such time as such Confidential Information:

         a)       is available generally to the public, other than as a result
                  of a breach of this Agreement; or,

         b)       is disclosed lawfully to the Receiving Party by a third party
                  who is free lawfully to disclose the same; or,

         c)       is developed independently by the Receiving Party; or,

         d)       The applicable period of confidentiality pursuant to
                  paragraph 3 has ended.

         e)       is already in the possession of the Receiving Party and is
                  subject to an existing agreement of confidence between the
                  parties.

6.       The Receiving Party shall use reasonable safeguards against the
         unauthorized disclosure of confidential and proprietary information
         and shall advise all of its employees and professional advisers having
         access to Confidential Information of the obligations hereunder.

7.       Upon expiration of the period of confidentiality, or sooner upon
         written request of the Disclosing Party, all Confidential Information

         Disclosing Party or destroyed, at the option and instruction of the
         Disclosing Party.

8.       It is understood that this Agreement is not intended to, and does not,

         proceed with any relationship or other transaction.
