               provided,  however,  NOVA shall use its best efforts to make such
               payments  within  fifteen  (15)  days  following  the end of each
               month. For example,  amounts payable to MSP for Referred Merchant
               revenues collected for March Transactions shall be paid to MSP by
               April 30,  but NOVA will  attempt to pay such  revenues  by April
               15).

         B.    Pass-Through  of Certain Fees.  NOVA and Member reserve the right
               to pass through to MSP certain  fees or penalties  imposed by any
               Credit Card  Association as a result of the  activities,  acts or
               omissions  of MSP.  Additionally,  MSP agrees to pay promptly any
               fees or penalties  imposed by the Credit Card  Associations  with
               respect to MSP's  registration as a service  provider for Member.
               MSP acknowledges that NOVA and Member, in their discretion and in
               accordance  with the terms of the Merchant  Agreements,  may pass
               through to Referred  Merchants  any fees or  expenses  related to
               implementing  changes to  software/hardware  requirements  deemed
               necessary  by the  Credit  Card  Associations  or  other  service
               providers.

5.       DUE CARE AND LIABILITY

MSP  hereby  agrees  to  indemnify  and  hold  NOVA,  Member,  the  Credit  Card
Associations,  the  Referred  Merchants  and  the  members  of the  Credit  Card
Associations  harmless from and against any claim,  demand,  loss,  financial or
otherwise,  damage,  liability  or cost  (including  reasonable  legal  fees and
expenses), caused by or in any way arising from: (i) any failure by MSP to fully
comply with the Rules and all other rules, regulations,  policies and procedures
of NOVA,  Member,  MasterCard,  VISA and any other similar Credit Card licensor;
(ii) any  breach or  default  by MSP of this  Agreement  or any other  agreement
between MSP and (a) NOVA,  (b) Member or (c) any  Referred  merchant;  (iii) any
negligent  or  wrongful  act of MSP in  performing  or failing  to  perform  the
obligations  hereunder;  or (iv) any  termination of this Agreement  pursuant to
Section 8 hereunder.  The obligations of MSP hereunder are not intended to cover
typical credit losses  (including  chargebacks)  incurred by NOVA or Member as a
result of Referred  Merchants'  refusal or inability to pay,  unless such credit
losses are  incurred by NOVA or Member as a result of any act or omission or MSP
described in (i) - (iv) above.

         F.    Dispute Resolution. Any controversy, dispute or claim arising out
               of, or in connection with this Agreement must be settled by final
               and  binding  arbitration  to be  held  in  Atlanta,  Georgia  in
               accordance with the rules of the American Arbitration Association
               ("AAA"),  as may be amended from time to time (the "AAA  Rules").
               Judgment upon award rendered by the arbitrators may be entered in
               any  court:  (i)  having   jurisdiction   thereof,   (ii)  having
               jurisdiction  over the party against whom enforcement  thereof is
               sought,  or (iii)  having  jurisdiction  over  any such  party's
               assets.  The procedures and law applicable during the arbitration
               of any  controversy,  dispute or claim will be both the AAA Rules
               and  the  internal  substantive  laws  of the  State  of  Georgia
               (excluding, and without regard to, its or any other

<PAGE>
               jurisdiction's  rules  concerning  any conflict of laws).  In any
               arbitration  pursuant  to this  Agreement,  the award of decision
               must be  rendered  by at least a  majority  of the  members of an
               arbitration  panel  consisting of three (3) members,  one of whom
               will be appointed by each of the parties hereto.  All arbitrators
               must be persons who are not employees, agents or former employees
               or agents of any  party.  In the  event  that any of the  parties
               hereto  fails to appoint an  arbitrator  within  thirty (30) days
               after  submission of the dispute to arbitration,  such arbitrator
               will be appointed by the AAA in accordance with the AAA Rules.

         G.       Force Majeure.  Neither party shall be liable to the other for
                  any failure or delay in its  performance  of this Agreement in
                  accordance  with its terms if such failure or delay arises out
                  of  causes  beyond  the  control  and  without  the  fault  or
                  negligence of such party.

         H.       Waiver.  Any waiver or delay by any party  hereto in asserting
                  or exercising any right,  shall not constitute a waiver of any
                  further  or other  rights of said  party.  If any part of this
                  Agreement   shall   be  held  to  be   invalid,   illegal   or
                  unenforceable, the validity, legality or enforceability of the
                  remainder of the Agreement shall not in any way be affected or
                  impaired thereby.

         1.       Attorney's  Fees. In the event any party hereto is determined,
                  in connection with a final and binding arbitration pursuant to
                  Section 6.F above, to have breached this  Agreement,  then the
                  non-defaulting  party shall be  entitled  to recover  expenses
                  incurred  in  enforcing  the  provisions  of  this  Agreement,
                  including reasonable attorneys' fees and costs.

         J.       Severability,  If any  provision  of this  Agreement  is found
                  illegal,  invalid  or  unenforceable,  such  finding  will not
                  affect any other provision hereunder.  This Agreement shall be
                  deemed modified to the extent necessary to render  enforceable
                  the provisions hereunder, and to comply with the Rules.
