     ------------------------------
     Franchisee acknowledges that all information that is disclosed to, or comes
     to the attention of Franchisee for purposes of the development or operation
     of any aspect of the PayPoint Network (herein "Information") is strictly
     confidential.  Franchisee agrees that Franchisee shall not use for any
     purpose other than Franchisee's use of the PayPoint Network or disclose
     said Information or knowingly permit Franchisee's employees or contractors
     to disclose said Information to any person outside Franchisor and
     Franchisee, or to any employee or contractor of Franchisor or Franchisee
     who does not have a specific need to know in performance of work hereunder.

     Franchisee acknowledges that participating Financial Institutions have a
     responsibility to their Cardholders to keep all records pertaining to
     Cardholders' banking transactions (herein "Cardholder Information")
     strictly confidential. Franchisee shall maintain the confidentiality of
     Cardholder Information.

     This paragraph shall not prevent the participating Financial Institutions
     from disclosing to their Cardholders information about such Cardholders'
     individual transactions.

     Franchisor agrees to use reasonable care to avoid disclosure of information
     relating to sales by Franchisee (herein "Sales Information") other than to
     Financial Institutions and other third parties who require access to Sales
     Information for purposes relating to Franchisee's use of or Franchisor's
     operation of the PayPoint Network.  Franchisor's obligation of non-
     disclosure shall not apply to any Sales Information which is or becomes
     available to the public other than through breach of this Addendum by
     Franchisor.  It is presently Franchisor's policy (which may be changed at
     any time by Franchisor at its sole option without notice) to destroy all
     records of Sales Information after two (2) years.  Franchisor's obligation
     of non-disclosure with respect to Sales Information shall terminate upon
     destruction of such Sales Information.

     The obligations of this Paragraph 16 shall survive termination of this
     Addendum.

17.  Service Mark License

     (a)  PayPoint, PayPoint Electronic Cashier, PayPoint Cashier, PayPoint
     Network, PayPoint and "Triangle" design, Electronic PayPoint, and the
     "Triangle" Design (hereinafter called "Marks") are service marks of
     Franchisor.

     (b)  During the term of this Addendum, Franchisor grants to Franchisee for
     use at Franchisee's Facility a non-exclusive license and right to use the
     marks in connection with the PayPoint Network as defined in Paragraph 3,
     but only so long as such services are performed using equipment approved by
     Franchisor and such equipment is maintained in good operating order and is
     operated in accordance with
<PAGE>

     Franchisor's training program and guidelines as promulgated from time to
     time by Franchisor.

     (c)  Franchisor shall have the right at all time to enter Franchisee's
     Facility for the purpose of inspecting the equipment used with the PayPoint
     Network, and to satisfy itself that services are being provided to the
     public according to Franchisor's standards.

     (d)  During the term of this Addendum, Franchisee shall be permitted to use
     and display the marks and other names and trade indicia used or authorized
     for use by Franchisor in connection with the PayPoint Network, but only in
     accordance with standards as set forth from time to time by Franchisor for
     the type of facility Franchisee is operating.  Franchisee shall only be
     permitted to use or display names, marks, symbols, or trade indicia
     belonging to participating Financial Institutions in conjunction with
     PayPoint equipment or on advertising upon Franchisor's prior approval, and
     such use and display is subject to whatever restrictions Franchisor or such
     institutions may prescribe.

     (e)  Franchisor expressly reserves the right to change, alter, modify, or
     withdraw the Marks, or any of them including the PayPoint name, at any time
     by giving Franchisee not less than thirty (30) days prior written notice
     thereof.  In the event of such change, alteration or modification,
     Franchisee agrees that it shall henceforth not use the mark or name which
     has been changed, altered, modified, or withdrawn. In the event the
     PayPoint name is changed, altered, modified, or withdrawn by Franchisor, it
     is agreed that the new name or Mark shall be substituted for "PayPoint
     Network" as it appears in this Addendum.

     (f)  Franchisee recognizes Franchisor's ownership and title to the Marks
     and shall not claim adversely to Franchisor any right, title, or interest
     thereto.  Particularly, Franchisee agrees, during and after the term of
     this Addendum, not to use, register or attempt to register as a trademark
     or as a trade or corporate name, or aid any third party in registering or
     attempting to register, any of the Marks or any marks, names, or symbols
     confusingly similar thereto, or incorporating one or more of the words in
     such marks or names as trademarks or service marks, or as trade or
     corporate names.

     (g)  All use of the Marks by Franchisee shall inure exclusively to the
     benefit of Franchisor and Franchisor may utilize such use in registering or
     defending such Marks.  Franchisee agrees to cooperate with Franchisor in
     providing evidence or testimony relative to or supporting Franchisee's use
     of said Marks.  Any registrations obtained by Franchisee contrary to
     Section (f) shall be held in trust for Franchisor and assigned by
     Franchisee to Franchisor upon Franchisor's request.
<PAGE>

     (h)  Upon termination of this Addendum or the Contract Dealer Gasoline
     Agreement, the undertakings and duties of Franchisee in Sections (f) and
     (g) shall survive and Franchisee shall cease using and remove the Marks and
     any names, marks, symbols, or trade indicia of participating Financial
     Institutions as set forth in Paragraph 14 of this Addendum.

18.  Force Majeure
     -------------
     No failure, delay or default in performing any obligation hereunder shall
     constitute default or breach of this Addendum to the extent that it arises
     from causes beyond the control and without fault or neglect of the party
     otherwise chargeable with failure, delay or default, including but not
     limited to:  action or inaction of governmental, civil or military
     authority; strike, lockout or other labor dispute; war, riot or civil
     commotion; theft, fire, flood, earthquake, natural disaster; or default of
     a common carrier.

     The party wishing to rely on this paragraph to excuse failure, delay or
     default shall, when the cause arises, give the other party prompt written
     notice of the facts constituting same, and when the cause ceases to exist,
     give prompt notice to the other party.

19.  Assignment
     ----------
     Franchisee shall not assign any of its rights or delegate any of its
     obligations pertaining to the PayPoint Network without the prior written
     consent of Franchisor. Any assignment or delegation made without such prior
     written consent shall be void and any assignment or delegation to which
     Franchisor consents must be in conjunction with an assignment of the
     Contract Dealer Gasoline Agreement.

     Franchisor or participating Financial Institutions to the retail prices
     charged or the quantity or quality of goods sold or services rendered by
     Franchisee to Cardholders or to customers of Franchisee.

                  Retailer Resolution of Cardholder Disputes
                  ------------------------------------------

PayPoint Network

     A cardholder dispute is initiated when a financial institution is notified
of its cardholders complaint.  If a cardholder informs a Franchisee that a
problem exists with a transaction made at the retail facility prior to the date
of the complaint, the Franchisee should inform the cardholder that the complaint
should be taken to the cardholder's financial institution.  All resolutions must
originate at the cardholder's financial institution.

     Examples of complaints:

     a)   Cardholder was charged twice for a purchase.

     b)   Cardholder never made the purchase, he/she was billed far by his/her
          financial institution.

Procedure for resolution of cardholder complaints by the PayPoint Network:

     1)   Cardholder disputes a transaction and notifies financial institution.

     2)   Financial institution then notifies the Franchisor switch of the
          problem.

     3)   The switch researches its records and makes every effort to find the
          disputed transaction in order to resolve the problem.

     4)   However, if the switch is unable to find the disputed transaction in
          the records maintained at the switch, the Franchisee will be notified
          via telephone. The switch contact person will provide the Franchisee
          with the data furnished by the financial institution and request a
          copy of the cardholder receipt and/or a copy of the Management Report
          Printer (MRP) report showing the disputed transaction information.

     5)   This telephone request will be immediately followed by a written
          request - a copy of the PayPoint Network Retailer Transaction
          Information Request form containing all the required transaction
          information. This form will be mailed to the Franchisee within one (1)
          working day of the telephone call. A copy of this form is attached.

     6)   The Franchisee will have only three (3) working days after receipt of
          the request to research the transaction and send the requested
          information to the financial institution listed on the form.
<PAGE>

     7)   The Franchisee is subject to chargeback of the transaction amount in
          question if the requested information is not sent within three (3)
          working days.

     8)   The Franchisee must send a copy of the completed PayPoint Network
          Retailer transaction Information Request form along with a copy of the
          customer receipt and/or MRP report (the same information furnished to
          the financial institution) to the Franchisor switch within one (1)
          working day of sending the information to the financial institution.
