or conditions hereof shall be valid unless it is written and signed by the Party

            ------------
be finally determined to be invalid or unenforceable under applicable law by a
court of competent jurisdiction, that part or provision shall be ineffective to
the extent of such invalidity or unenforceability only, without in any way
affecting the remaining parts of said provision or the remaining provisions of
this Agreement.

     5.6    Assignment.  The Parties hereby warrant and represent that they have
            ----------
not assigned or in any way transferred or conveyed all or any portion of the

without which they would not have entered into it.

     5.7    Consultation. The Parties acknowledge that they have had the

     5.10   Governing Law.  This Agreement is made and entered into in the
            -------------
State of Georgia and will in all material respects be interpreted, enforced, and
governed under the laws of said state.

     5.11   Adverse Regulatory Determination. If any Regulatory Authority
            --------------------------------
determines, at any time, that this Agreement, in whole or in part, is unlawful
or unenforceable, or makes any other determination adversely affecting the
Agreement, any Service Agreement, any PTEK Entity or any successor or assign of
any PTEK Entity, then the Parties shall each exercise their best efforts within
a period of ninety (90) days commencing with the date of said Adverse Regulatory
Determination ("Cure Period") both to (i) comply therewith and (ii) to
                -----------
renegotiate in good faith to arrive at a new agreement reflecting to the fullest
extent permitted by law, the bargain struck between the Parties pursuant to this
Agreement or the applicable Service Agreement.

     5.12   Arbitration. The Parties shall attempt to resolve in good faith any
            -----------
disputes arising from this Agreement, including any Service Agreement.
Specifically, prior to instituting formal legal action, the Parties will refer
any dispute to authorized representatives for consideration and potential
resolution.  Initially, such representatives shall be Dan Mell for PTEK and
David Myers for MCI WorldCom.  In the event that the Parties cannot resolve a
dispute through this executive escalation mechanism, the dispute shall be
submitted to the American Arbitration Association ("AAA") for final and binding
                                                    ---
arbitration before a single arbitrator ("Arbitrator") conducted in accordance
                                         ----------
with the United States Arbitration Act, 9 U.S.C. 1-16 et seq. ("USAA").  The
                                                                ----
arbitration shall be held in Atlanta, Georgia.  The costs of arbitration,
including the fees and expenses of the Arbitrator, shall be shared equally by
the Parties.  Each party shall bear the cost and attorneys' fees of preparing
and presenting its own case.  Notwithstanding anything in this paragraph to the
contrary, including, but limited to, the AAA Rules of Commercial Arbitration
and/or the USAA, the Parties agree that the Arbitrator shall have the sole
authority to determine any and all procedures related to discovery in any
arbitration between the Parties, including, but not limited to, whether any
discovery will be permitted and the type of discovery that will be permitted.
Notwithstanding any choice of law provision in this Agreement, any controversy
whether an issue is arbitrable shall be determined by the Arbitrator and there
shall be no right of appeal from this ruling.  The Arbitrator shall have the
authority to grant injunctive relief, including temporary injunctive or
equitable relief, consistent with the laws controlling such remedies.  Except
for any claim based on actual fraud, the Arbitrator shall have no authority to
award punitive or exemplary damages and the parties expressly waive their right
to such damages.  Any decision of the Arbitrator is final and binding on the
Parties.  The Parties expressly agree they will take no action to vacate the
Arbitrator's decision.  The award may be enforced in any court of competent
jurisdiction.  All post-award proceedings shall be governed by the USAA.
