          3.1  Software License.  Subject to the terms and conditions of this
               ----------------                                              
Agreement, for each Purchase Order issued by MCI and accepted by Genesys,
Genesys shall grant MCI a [*] (except as otherwise provided in Section 14.1),
[*] license to use the applicable Licensed Software in [*] solely on the
Designated CPU, [*] for the use by the number of Simultaneous Users for such
Designated CPU specified in the Purchase Order for the purposes of MCI's
business and the business(es) of its Affiliates.

          3.2  Delivery and Acceptance.
               ----------------------- 

          (A) Upon final acceptance by Genesys of a Purchase Order, MCI shall
pay the license fee referenced and in accordance with the payment schedule
specified in the Purchase Order or an exhibit or schedule thereto ("License
Fee").  The initial installation for the Licensed Software will be performed by
Genesys during MCI's normal working hours and will include the products and
services listed in the Purchase Order, to be provided according to the schedule
specified therein.  Genesys will notify MCI when installation of the Licensed
Software has been completed.  Genesys agrees to deliver, at the time of such
installation, Documentation in form and substance reasonably satisfactory to
MCI.  Following installation, unless otherwise specified in the Purchase Order,
MCI shall have a period of [*] days for inspection and testing of the Licensed
Software to determine conformance with the Applicable Specifications for the
Licensed Software (the "Acceptance Criteria"). The designation in any Purchase
Order of an acceptance period of less than [*] days shall not be effective
unless such Purchase Order is countersigned by an MCI representative of Director
level. If any feature or module of the Licensed Software is found not to
conform, MCI shall, within the inspection period, notify Genesys and provide a
detailed description of such defects. Following confirmation by Genesys of such
defects, Genesys will provide MCI with a corrected version of the Licensed
Software, and if Genesys fails to deliver such corrected version within a
reasonable time (not to exceed [*] days from MCI's notification to Genesys), MCI
will have the option of canceling the Purchase Order within the next [*]
business days. In the event MCI exercises such option, MCI shall return all
copies of the Licensed Software and the Documentation to Genesys; Genesys shall
promptly refund to MCI all amounts paid by MCI to Genesys pursuant to the
applicable Purchase Order, and neither party shall have any future obligations
or liability under that Purchase Order with respect to the relevant Licensed
Software. Such full refund and cancellation shall be MCI's sole and exclusive
remedy for rejection of the Licensed Software.

          (B) Upon acceptance by MCI of the Licensed Software pursuant to
Section 3.2(A) or if MCI fails to notify Genesys of any defects within the
inspection period specified therein, the Licensed Software shall be deemed
accepted.  MCI's sole remedy for correction of problems after acceptance shall
be under the Limited Warranty set forth in Article 5 below.

make a reasonable number of copies of Documentation for the use of MCI's
employees in their use of the Software.  MCI agrees to reproduce and include any
copyright or proprietary notices of Genesys on all copies, in whole or in Part,
of the Licensed Software or Documentation.

however, that MCI provides Genesys with written notice of such hardware
substitution, including information regarding the replacement hardware as
required for the Designated CPU in Exhibit A, within seven (7) days of such
replacement.

          3.5  No Other Rights.  This Agreement transfers to MCI neither title
               ---------------                                                
nor any proprietary or intellectual property rights to the Licensed Software,
Documentation or any copyrights, patents or trademarks embodied or used in
connection therewith, and except for the rights expressly granted herein, MCI
receives no other rights in or to the Licensed Software, Documentation and
intellectual property, either by implication, estoppel or otherwise.
Accordingly, MCI shall have no other rights with respect to the Licensed
Software other than the license expressly set forth herein.

               (6) Is identified by Owner as no longer proprietary or
          confidential.

          (B) In the event Recipient is required by law, regulation or court
order to disclose any of Owners Confidential Information, Recipient will
promptly notify Owner in writing prior to making any such disclosure in order to
facilitate Owner seeking a protective order or other appropriate remedy from the
proper authority.  Recipient agrees to cooperate with Owner in seeking such
order or other remedy.  Recipient further agrees that if Owner is not successful
in precluding the requesting legal body from requiring the disclosure of the
Confidential Information, it will furnish only that portion of the Confidential
Information which is legally required and will exercise all reasonable efforts
to obtain reliable assurances that confidential treatment will be accorded the
Confidential Information.

written request or the termination or expiration of this Agreement, and shall
not thereafter be retained or used in any form by Recipient.

          9.4  Terms.  The parties agree that the terms and conditions of this
               -----                                                          
Agreement shall be treated by each party as the Confidential Information of the
other party, and that neither party shall disclose the contents of this

                        ARTICLE 12 -- SOURCE CODE ESCROW

          12.1 Within thirty days of the signing of this Agreement and from time
to time thereafter, but not more than sixty days following any subsequent Update
of the Licensed Software, to secure MCI's rights hereunder Genesys shall place
copies of its then current source code and documentation (the "Escrow
Materials") for all the Licensed Software with Data Securities International,
Fort Knox Escrow Services, Inc. or another independent escrow agent mutually
satisfactory to MCI and Genesys on the standard terms and conditions of such
agent and in accordance with the following provisions of this Article 12.

          12.2 Release of the Escrow Materials to MCI shall be on terms and
conditions (including notice, redeposit and other provisions) to be agreed in
the escrow agreement, but such release shall be granted whenever:

          (A) Genesys is unable or unwilling to perform its maintenance and/or

custodian, trustee or liquidation of itself or of all or a substantial part of
its property, or its liquidation, reorganization or dissolution.

          12.3 MCI is hereby granted a license to use such Materials upon their
release to MCI only to perform and authorize the performance of such maintenance
and/or support, and for no other purpose.  Such escrow shall be established and
maintained at the expense and for the sole benefit of MCI.  Genesys warrants
that the Escrow Materials will accurately reflect the then current version of
the Licensed Software and will be sufficiently detailed and documented so as to
permit a reasonably competent computer professional conversant in the
languages(s) used by the Licensed Software to understand, maintain and modify
the Licensed Software.

          12.4 Any dispute or disagreement between the Parties arising out of
this Article 12 shall be resolved by arbitration in accordance with Section

sixty (60) days of the demand for arbitration, through no fault or act of delay
by MCI, the Escrow Materials shall be released to MCI notwithstanding the
pendency of any such arbitration.  At all time, the parties shall use their best
efforts to expedite the arbitration proceedings.  If the arbitrator(s)
ultimately find that under the terms of this Agreement release of the Escrow
Materials to MCI should not have occurred, MCI shall return the Escrow Materials
to the Escrow Agent.

          12.5 The obligations of Genesys under this Article 12 shall remain in
effect until the termination of the maintenance and support obligations of
Genesys.

                       ARTICLE 13 -- TERM AND TERMINATION

          13.1 Term and Termination.  MCI may terminate this Agreement or any
               --------------------                                          
license obtained hereunder upon ninety (90) days' prior written notice to

          13.2 Return of Materials.  Upon termination of any license for any
               -------------------                                          
reason, MCI shall immediately discontinue use of the relevant Licensed Software
and Documentation and within ten (10) days certify in writing to Genesys that
all copies of the Licensed Software and Documentation, in whole or in part, in
any form, have either been returned to Genesys or destroyed in accordance with
Genesys's instructions. Upon such termination Genesys shall immediately refund
to MCI any related unamortized prepayments made by MCI for maintenance and
support.

          13.3 Termination by Genesys.  Genesys may terminate a license granted
               ----------------------                                          
hereunder with respect to any one or more Purchase Orders if MCI commits any
material breach of the license grant set forth in Section 3 or the
confidentiality

                                      12


 
obligations in Section 9 above and fails to remedy such breach within thirty
(30) days after written notice by Genesys of such breach and such material
breach causes irreparable damage to Licensor or cannot adequately be remedied by
the payment of monetary damages by Genesys.

          13.4 Effect of Termination.  Notwithstanding any termination of this
               ---------------------                                          
Agreement, the following provisions shall survive: Articles 3 (except to the
extent Genesys terminates this Agreement as a result of MCI's material breach of
the license granted by such Article), 4 (to the extent of any amounts due and
owing as of such termination), 5, 7, 8, 9, 10, 11, 12 and 14.  All other rights
and licenses granted hereunder will cease upon termination.

assign or otherwise dispose of its rights or obligations hereunder, by operation
of law or otherwise, without the prior written consent of the other party.
Notwithstanding the foregoing, (i) MCI may transfer or assign its rights and
obligations, in whole or in part, to an Affiliate, provided that MCI shall,
however, notify Genesys of such transfer or assignment, and (ii) Genesys may
assign this Agreement as part of the sale of all or substantially all of its
assets or as part of any transaction resulting in a change in control of
Genesys, provided that Genesys shall notify MCI of such assignment and that MCI
shall have the option of terminating (without prejudice to other provisions of
this Agreement) any development obligations then in effect.

          14.2 Captions.  The captions used in this Agreement are included for
               --------                                                       
convenience only and shall not be considered part of this Agreement for any
purpose.

          14.3 Governing Law.  This Agreement shall be governed, construed and
               -------------

to conflict of laws principles.

          14.4 Dispute Resolution.  Any dispute arising out of or related to
               ------------------                                           
this Agreement, which cannot be resolved by negotiation, shall be settled by
binding arbitration in accordance with the J.A.M.S/ENDISPUTE arbitration Rules
and Procedures ("Endispute Rules"), as amended by this Agreement. The costs of
arbitration, including the fees and expenses of the arbitrator, shall be shared
equally by the parties unless the arbitration award provides otherwise. Each
party shall bear the cost of preparing and presenting its case. The parties
agree that this provision and the arbitrator's authority to grant relief shall
be subject to the United States Arbitration Act, 9 U.S.C. 1-16 et seq. ("USAA"),
the provisions of the Agreement, and the ABA-AAA Code of Ethics for Arbitrators
in Commercial Disputes. The parties agree that the arbitrator shall have no
power or authority to make awards or issue orders of any kind except as
expressly permitted by this Agreement, and in no event shall the arbitrator

                                      13


 
have the authority to make any award that provides for punitive or exemplary
damages. The arbitrator's decision shall follow the plain meaning of the
relevant documents, and shall be final and binding. The award may be confirmed
and enforced in any court of competent jurisdiction. All post-award proceedings
shall be governed by the USAA. The location of such a proceeding shall be
mutually agreed by the parties or if agreement cannot be reached, then the
location chosen by the arbitrator. This provision shall not preclude either
party seeking injunctive relief as permitted hereunder in any court of competent
jurisdiction. Unless the parties otherwise agree, all arbitration proceedings
shall take place in San Francisco, California.

          14.5 Jurisdiction.  The federal and state courts within San Francisco,
               ------------                                                     
California, shall have exclusive jurisdiction with respect to any action sought
by either party to enforce Section 14.4 above. Each party hereto expressly
consents to the personal jurisdiction of, and venue in, such courts and service
of process being effected upon it by registered mail and sent to the address set
forth at the beginning of this Agreement.

          14.6 Independent Contractors.  The relationship of Genesys and MCI
               -----------------------                                      
established by this Agreement is that of independent contractors, and nothing
contained in this Agreement shall be construed (i) to give either party the
power to direct or control the day-to-day activities of the other or (ii) to
constitute the parties as  partners, joint venturers, co-owners or otherwise as
participants in a joint or common undertaking.

          14.7 Severability.  If any provision of this Agreement is held to be
               ------------                                                   
invalid by a court of competent jurisdiction, then the remaining provisions
shall nevertheless remain in full force and effect.  The parties further agree
to negotiate in good faith a substitute, valid and enforceable provision that
most nearly effects the parties' intent and to be bound by mutually agreed
substitute provision.

          14.8 No Waiver.  The failure of either party to enforce at any time
               ---------                                                     
any of the provisions of this Agreement shall not be deemed to be a waiver of
the right of such party thereafter to enforce any such provisions.

          14.9 Force Majeure.  Except for the obligation to make payments,
               -------------                                              
nonperformance of either party shall be excused to the extent that performance
is rendered impossible by strike, fire, flood, governmental acts or orders or
restrictions, failure of suppliers, or any other reason where failure to perform
is beyond the reasonable control of the nonperforming party.

          14.10  Notices.  Any required notices hereunder shall be given in
                 -------                                                   
writing at the address of each party set forth above, or to such other in the
manner contemplated herein, and shall be deemed served when delivered or, if
delivery is not accomplished by reason or some fault of the addressee, when
tendered.

regulations of other applicable U.S. Government organizations.
