         (ii) Termination of Exclusivity. At any time that EncrypTix fails to
              --------------------------
meet the criteria to maintain exclusivity set forth in Section 2(b)(i), the

the exclusivity set forth in this Section 2(b) against all Third Parties and
Stamps, with the following limited exceptions:

               (A) Each of Stamps' existing (as of the Effective Date) non-
exclusive licenses, as set forth on Schedule 2(b)(iii)(A) attached hereto (the
                                             ------------
"Existing Agreements"), shall remain in full force and effect until its
expiration and the expiration of any renewal periods exercisable and exercised
by the respective licensees, and EncrypTix shall not be entitled to enforce its
exclusivity hereunder with respect to such Existing Agreements; provided that
                                                                --------

obligations under this Agreement or other agreements with EncrypTix and/or to
provide EncrypTix with technical support and maintenance services; (ii) use the
Stamps Technology and all Derivative Works thereof for all purposes outside of
the Travel and Events Fields of Use; and (iii) copy, reproduce and create
Derivative Works of the Stamps Technology (provided that copying pursuant to
this clause (iii) shall not occur to permit, or in connection with, commercial
exploitation of the technology by Stamps in the Travel and Events Fields of Use
while exclusivity continues for that field of use).

               (iv) Non-Exclusivity of Financial Services Field of Use;
                    ---------------------------------------------------
Potential Termination. The license granted to EncrypTix pursuant to Section 2(a)
---------------------
is a non-exclusive license of rights in and to the Stamps Technology in the
Financial Services Field of Use (except that, if an activity should exist that
is within both the Travel and Events Fields of Use an the Financial Services
Field of Use, the license will be exclusive as to that activity). Stamps may
terminate EncrypTix' license in the Financial Services Field of Use in the event
that EncrypTix: (i) fails to obtain no less than twenty million dollars
($20,000,000) of equity financing prior to the first anniversary of the
Effective Date; or (ii) fails at any time to continue as a going concern or to
maintain its ability to pay its debts as they become due.

               (v) Extension of Exclusivity in the Travel and Events Fields of
                   -----------------------------------------------------------
Use. Upon the expiration of the [***]* year period of exclusivity defined in
----
Section 2(b)(i), the license granted to EncrypTix pursuant to Section 2(a) shall
remain exclusive with respect to any exclusive field of use (i.e., the Travel
Field of Use or the Events Field of Use, or, if applicable, both of those fields
of use) for an additional [***]* (to the extent that such exclusivity was not
                           ---
theretofore terminated pursuant to Section 2(b)(i) or 2(b)(ii)) if, in [***]*,
                                                                        ---
EncrypTix shall have issued more than [***]* tickets in revenue-generating (for
                                       ---
EncrypTix) issuances in such field of use.

         (c) Sublicensed Matter.
             ------------------

               (i) To the extent that any of the Stamps Technology is acquired
by or licensed to Stamps from any Third Party licensor that is not under direct
or indirect common ownership with Stamps ("Third Party Technology"), the grant
of license or sublicense rights to EncrypTix with respect to all Third Party
Technology is subject to Stamps' right under its license from each respective
Third Party licensor (the "Primary License") to sublicense the Third Party
Technology, and, consistent with the rights granted to EncrypTix under Section
2.1(a) but subject to the further provisions in this paragraph, Stamps shall
grant to EncrypTix such rights as the Primary License permits. Unless EncrypTix
declines all rights under licenses of Third Party Technology as provided in the
following sentence, EncrypTix shall pay or reimburse Stamps for appropriately
prorated expenses and acquisition costs and any incremental royalties which
Stamps becomes obligated to pay to such Third Party licensor by reason of
EncrypTix' license or sublicense of, or exploitation of, the Third Party
Technology. In connection with future acquisitions of Third Party Technology,
Stamps will, to the extent consistent with any applicable confidentiality
requirements and its other contractual commitments, provide EncrypTix with (i) a
copy of such new license agreements and information on the subject technology
and (ii) a period of ten (10) business days to decline, by notice to Stamps, any
rights thereunder; in which case, notwithstanding the foregoing provisions of
this Section 2, EncrypTix shall have no rights to the Third Party Technology
licensed to Stamps thereunder.

     (ii) Stamps will maintain accurate records with regard to its obligations
and payments for Third Party Technology and the amounts due from EncrypTix in
connection with Third Party Technology. For the purpose verifying its payment
obligations in connection with Third Party Technology, EncrypTix (or its
representative) will have the right to conduct a reasonable inspection of the
portions of such records that are relevant to those EncrypTix' payment
obligations. Any such audit may be conducted after ten (10) business days prior
written notice to Stamps. EncrypTix shall bear the expense of any audit
conducted pursuant to this paragraph unless such audit shows overcharges in the
amounts reported as payable to Stamps or actually paid to Stamps by EncrypTix
for Third Party Technology for any quarterly period in excess of the greater of
(a) ten percent (10%) of the actual or reported amounts paid or payable to
Stamps for Third Party Technology for such period and (b) Five Thousand Dollars
($5,000.00), in which event Stamps shall bear the reasonable expenses of the
audit.

     (d) Additional Field of Use.  During the term of this license, EncrypTix
         -----------------------
shall have the right to petition Stamps to expand the license granted hereunder
to specific fields of use in addition to the Travel and Events Fields of Use and
the Financial Services Field of Use. Stamps shall consider such petitions in
good faith, however, any grant of additional fields of use (whether exclusive or
            -------
non-exclusive) will be at Stamps' sole discretion and for additional
compensation.

     (e) Restrictions.  EncrypTix shall not (and shall not allow any Third Party
         ------------
to): (i) decompile, disassemble, or otherwise reverse engineer or attempt to
reconstruct or discover any source code, underlying ideas, or algorithms of the
Stamps Technology by any means whatsoever (except to the extent that applicable
law prohibits reverse engineering restrictions), (ii) remove any product
identification, copyright, patent or other notices, (iii) except to the extent
expressly authorized in this Section 2, modify or incorporate into or with other
software or create a derivative work of any part of the Stamps Technology, or
(iv) sublicense or assign any rights hereunder to any Third Party (including
without limitation, end-user licenses) unless otherwise expressly permitted
under this Section 2.

     (f) Patent Markings and Copyright Notices.  EncrypTix shall reproduce on or
         -------------------------------------
within all products, software, webpages and other media incorporating the Stamps
Technology and on any related media all patent markings and copyright notices as
supplied by Stamps and such additional notices as may reasonably be requested by
Stamps.

     (g) Exception to License.  Notwithstanding anything else in this Agreement,
         --------------------
no license whatsoever is or will be conveyed or granted by this Agreement as to:

         (i) the source code version of any Stamps Technology that consist(s) of
[***]*, provided that nothing in this clause "i" limits EncrypTix's rights to
 ---
obtain object code versions of the foregoing;"

         (ii) a new version of, or a replacement for, an item of source code not
furnished to EncrypTix pursuant to the preceding clause "i" provided that Stamps
                                                            -------------
will consult with EncrypTix and may include in the license new source code that
would be included but for this restriction unless Stamps determines that it has
legitimate security or other reasons not to do so, and provided that nothing in
this clause "ii" limits EncrypTix's rights to obtain object code versions of the
foregoing; or

         (iii) as to which licensing and provision to EncrypTix as provided in
this Agreement would (A) violate applicable laws or regulations including,
without limitation, Postal Service or Department of Commerce laws or

or (ii) exercise, or attempt to exercise, any proprietary rights in the
Derivative Works, other than as expressly set forth herein and in any other
written agreement(s) that may be entered into by the Parties. To the extent that
any Derivative Works of the Stamps Technology are created by or for EncrypTix,
such Derivative Works shall be included in the license granted under Section 2

     (c) EncrypTix Technology. Except as provided in Section 5(b) and 5(d),
         --------------------
EncrypTix shall own all right, title and interest in and to all intellectual
property created by EncrypTix (the "EncrypTix Technology"). EncrypTix hereby
grants to Stamps a non-exclusive, fully paid-up, royalty free, perpetual,
irrevocable and worldwide license, with right to sublicense, to use, reproduce,
distribute, transmit, publicly perform and display, modify and create derivative
works of EncrypTix Technology developed during the Technology Transfer Term and
products embodying the EncrypTix Technology developed during the Technology
Transfer Term, and to make, use, offer for sale and sell products and services
that incorporate the EncrypTix Technology developed during the Technology
Transfer Term or modifications thereof, each for exploitation solely in the
Mailing and Shipping Field of Use. Stamps agrees that it will not, at any time
during or after this Agreement, (i) do anything which may adversely affect the
validity or enforceability of the EncrypTix Technology (including any act, or
assistance to any act, which would infringe or lead to the infringement of the
EncrypTix Technology), or (ii) exercise, or attempt to exercise, any proprietary
rights in the EncrypTix Technology, other than as expressly set forth herein and
in any other written agreement(s) that may be entered into by the Parties.

     (d) Co-Development. Any intellectual property resulting from co-development
         --------------
efforts of EncrypTix and Stamps that do not constitute Derivative Works of the
Stamps Technology shall be owned by the parties jointly (the "Joint
Technology"). Each of EncrypTix and Stamps hereby grants to the other party a
non-exclusive, fully paid-up, royalty free, perpetual, irrevocable and worldwide
license to use, reproduce, distribute, transmit, publicly perform and display,
sublicense, modify and create derivative works of the Joint Technology and
products embodying the Joint Technology, and to make, use, offer for sale and
sell products and services that incorporate Joint Technology or modifications

         --------
the Joint Technology in the Travel and Events Fields of Use, and Stamps shall
have the sole right to use and sublicense the Joint Technology in the Mailing
and Shipping Field of Use.

6. CONFIDENTIAL INFORMATION

     (a) Treatment of Confidential Information.  Stamps and EncrypTix recognize
         -------------------------------------
that, in connection with the preparation or performance of this Agreement, each
of them may disclose to the other its Confidential Information, or each may
obtain Confidential Information of the other through preparation of or
performance under this Agreement, including by the creation of materials and the
development of technology and techniques that are not generally known. Except as
permitted in connection with the license rights granted pursuant to this
Agreement, a party who obtains any Confidential Information of the other agrees
to maintain the confidential status of such Confidential Information, not to use
any such Confidential Information for any purpose other than the purpose for
which it was originally disclosed to the receiving party, to disclose such
Confidential Information only to those of its employees having a need to know
such information, and not to disclose any of such Confidential Information to
any Third Party other than consultants, contractors and advisors under a written
obligation to keep such information confidential and to use it only for the
purposes set forth above. Neither Stamps and EncrypTix shall disclose the
other's Confidential Information to any person except on a "need-to-know" basis.

     (b) Stamps Security Policies.  EncrypTix shall comply at all times with
         ------------------------
Stamps' security policies as they may be amended from time to time. Stamps shall
keep EncrypTix reasonably advised of Stamps security policies and changes
therein.

     (c) Required Disclosure.  The Parties recognize that each may be required
         -------------------
by law or order of a court or other governmental authority, SEC regulations, or
the like, to disclose the other's

                                       9
<PAGE>

Confidential Information, and that each shall endeavor to stop or limit such
disclosure and afford the other the opportunity to do so. Each party shall
immediately give the other party written notice of any anticipated disclosure
pursuant to this Section 6(c) and will provide reasonable assistance to the
other party, at the other party's expense, in resisting such disclosure. Without
limiting the foregoing, any party making filings with the Securities and
Exchange Commission shall include a copy of this Agreement only if and to the
extent required and shall withhold, or use its best efforts to prevent public
disclosure of, Schedule 2(g) hereto. In the case of filings made by EncrypTix,
EncrypTix shall also consult with Stamps, withhold Schedule 2(g) if possible,
seek confidential treatment of Schedule 2(g) if it cannot be withheld entirely,
and, to the extent necessary to secure confidential treatment of the material
therein that Stamps seeks to protect, redact such schedule.

     (d) Third-party Confidential Information. Any confidential information of a
         ------------------------------------
third party disclosed by a party to the other shall be considered Confidential
Information hereunder and shall be subject to such additional restrictions as
may be imposed by such third party on the discloser and communicated in writing
by the discloser to the recipient.

     (e) Injunctive Relief. Each party agrees that if a court of competent
         -----------------
jurisdiction determines that one party has breached, or attempted or threatened
to breach, any of its confidentiality obligations to the other party or its
proprietary rights, such other party will be entitled to obtain appropriate
injunctive relief and other measures restraining further attempted or threatened
breaches of such obligations.

7. ENFORCEMENT AND DEFENSE

     (a) Control.
         -------

         (i) Stamps shall have the right, but not the obligation, to control the
investigation, enforcement, defense and settlement of any action with respect to
the Stamps Technology (including any action in which the ownership, validity, or
enforceability of any of the Stamps Technology is or may be put at issue or in
which any third party asserts or may assert that use of the Stamps Technology
(including Derivative Works prepared by or for EncrypTix pursuant to
authorization in this License Agreement) by Stamps or by EncrypTix infringes or
will infringe the intellectual property rights of one or more third parties)
provided that, with respect to copyrights and trade secrets only, and only for
--------
claims within the Travel and Events Fields of Use, EncrypTix shall have the
right, at its own cost and expense, to participate in such action with counsel
of its choice.  Except as provided in Section 2(c)(i), any settlement that (A)
grants to third parties any rights to the Stamps Technology in the Travel and
Events Fields of Use, or (B) that limits any of EncrypTix' rights in any
Licensed Fields of Use, shall be subject to EncrypTix' prior written consent,
which shall not be unreasonably withheld.

         (ii) If Stamps elects not to pursue any enforcement or defense of an
action referred to in the first sentence of the immediately preceding paragraph
"i", EncrypTix shall have the right to pursue such enforcement or defense on its
own, solely with respect the validity and use of the Stamps Technology in the
Licensed Fields of Use, including the settlement of any claims solely within the
Licensed Fields of Use. Any settlements that may affect the Stamps Technology
outside of the Licensed Fields of Use will require Stamps' prior written
consent, which shall not be unreasonably withheld.

     (b) Notice.  Each party shall provide the other prompt notice of any claims
         ------
of infringement of which such party becomes aware.

                                       10
<PAGE>

     (c) Assistance.  Each party will provide the other all assistance
         ----------
reasonably necessary to enforce or defend the Stamps Technology.

     (d) Sharing of Economics. If EncrypTix participates in an action with
         --------------------
respect to the Stamps Technology, then Stamps and EncrypTix will share equitably
the benefits (net of their respective burdens) of such enforcement action, such
sharing to reflect: (i) the total benefits received collectively by Stamps and
EncrypTix as a result of the action (including any appeals, etc.) and (ii) the
extent to which those benefits reflected the efforts and contributions made in
such action by Stamps or by EncrypTix respectively.

8. TERM AND TERMINATION

     (a) Term.  Unless earlier terminated under the provisions of this Section,
         ----
this Agreement shall remain in full force and effect perpetually.

     (b) Termination for Breach Generally.
         --------------------------------

         (i) Notwithstanding the provisions of Section 8(a), this Agreement may
be terminated by either party (A) following a determination by the arbitrator
pursuant to the expedited arbitration procedures set forth in Schedule 8(b),
that the Terminating Party (as defined in Schedule 8(b)) would be likely to
prevail at a full trial on the merits on the claim that the Responding Party (as
there defined) has committed a material breach of the Agreement, unless (i) the
breach is curable and (ii) the Responding Party provides notice of its intent to
cure it and such cure is effected within the time stated in paragraph "9" of
Schedule 8(b) or (B) after a judicial declaration or finding to the effect of
the determination referred to in clause "A" above (or that a material breach has
actually occurred) unless the breach is curable, a notice of intent to cure is
provided thereafter, and the breach is cured as described (and pursuant to the
time provisions referred to) in clause "A.ii" above. A breach involving an
improper release of any Stamps Technology is not effectively cured unless and
until (A) such improper release ends and (B) Stamps receives reasonable
assurances that it will not suffer substantial injury or loss as a consequence
of such improper release and reasonable assurances that such a breach will not
occur again.

         (ii) The parties to this agreement will use their best efforts to agree
on the pre-approved arbitrators for purposes of Schedule 8(b) hereof within
fifteen calendar days after the date of this agreement and to list them on
Attachment B to Schedule 8(b) hereof. If at least four (4) such pre-approved
arbitrators are not so agreed upon in a specific order of priority as provided
in that Schedule before the time that one party or the other to this Agreement
delivers a written notice of material breach by the other party to such other
party (or within five business days thereafter, as to which the parties will use
their good faith efforts to agree), the requirement for an arbitrator's
determination prior to the commencement of a cure period and prior to a
termination of this Agreement for a material beach shall not apply. In that
event, if there actually has been a material breach by one party, the other
party may provide written notice thereof and terminate this agreement thirty
calendar days thereafter unless the breach is curable and is cured within that
thirty-day period.

         (iii) Nothing in Sections 8(a) or 8(b) shall limit the right of either
party to seek and obtain judicial relief including, without limitation: (a)
injunctive or other judicial relief to prevent or halt an improper disclosure,
release, or use of either party's Intellectual Property Rights; (b) damages or
other relief for a breach of this Agreement; and (c) a declaration that a
material breach has occurred.

                                       11
<PAGE>

     (c) Other Events of Early Termination.  Stamps may, in Stamps' sole and
         ---------------------------------
absolute discretion, terminate this Agreement immediately by notice to EncrypTix
in the event of any of the following events: (i) except to the extent that an
opportunity for cure may be available in accordance with the last sentence of
this paragraph and a cure may be effected as provided there, any sublicense by
EncrypTix of rights to any Stamps Competitor other than a sublicense by
EncrypTix in the ordinary course of its business of only client-side software to
such entity as an end user consistent with the rights of EncrypTix in Section 2
hereof; (ii) any assignment of rights (including a Change of Control) by
EncrypTix to any Stamps Competitor; (iii) a Change of Control of EncrypTix at a
valuation of that entire company, on a fully diluted basis, of less than [***]*
dollars; and (iv) to the extent permitted under law, in the event that (A) any
proceeding shall be instituted by or against EncrypTix seeking to adjudicate it
bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief or composition of it or its debts
under any law relating to bankruptcy, insolvency or reorganization or relief of
debtors, or seeking an entry of an order for relief or the appointment of a
receiver, trustee or other similar official for it or any substantial part of
its property (if such proceeding shall not have been dismissed without any such
relief within sixty days after such institution) or (B) EncrypTix shall take any
action to authorize any of the foregoing actions, or (C) EncrypTix shall be
unable at any time to pay its debts as they become due. In the case of clause
"i" above only, EncrypTix shall have an opportunity to cure the event allowing
termination if it provides notice to Stamps within twenty days after such
sublicense occurs; and such a cure shall be deemed to have been effected if,
within thirty (30) days after receipt of notice from Stamps that the licensee is
a Stamps Competitor, EncrypTix terminates such sublicense fully and effectively.

     (d) No Waiver or Release.  Termination of this Agreement by either party
         --------------------
shall not act as a waiver of any breach of this Agreement and shall not act as a
release of either party from any liability for breach of such party's
obligations under this Agreement. No termination of this Agreement shall affect
the stock ownership or other rights or privileges obtained by Stamps in the
organization and capitalization of EncrypTix or, except as provided in other
agreements between the parties, the rights of the parties under those
agreements.

     (e) Return of Confidential Information.  Within thirty (30) calendar days
         ----------------------------------
after termination of this Agreement, each party hereunder shall either deliver
to the other, or destroy, all copies of any materials provided hereunder in its
possession or under its control, and shall furnish to the other party an
affidavit signed by an officer of its company certifying that to the best of its
knowledge, such delivery or destruction has been fully effected.

     (f) Survival of Certain Provisions.  Notwithstanding the termination of
         ------------------------------
the Agreement for any reason, the provisions of Sections 5; 6; 8(e) and (f); 9;
10; and 11(c), (d), (e), (h), (i) and (k) of this Agreement shall survive such
termination indefinitely. In addition, any obligations which expressly or by
their nature are to continue after termination of the Agreement shall survive
and remain in effect.

provided that at least one of them is commercially reasonable: (i) procure for
-------------
EncrypTix the right to continue using the Stamps Technology; (ii) modify the
Stamps Technology to perform its intended function without infringing Third

     (f) Exception.  The provisions of Sections 9(c) and (d) shall not apply (i)
         ---------
if the Stamps Technology is modified by EncrypTix or EncrypTix' designee (which
includes Stamps acting as required by EncrypTix under the Incubation Agreement)
(it being agreed that a Derivative Work prepared by EncrypTix or its designee
shall be deemed "modified" Stamps Technology notwithstanding that such
Derivative Work may fall within the definition of "Stamps Technology"), but
solely to the extent the alleged Infringement is caused by such modification;
(ii) if the Stamps Technology is combined with products, processes or materials
by or for EncrypTix but solely to the extent the alleged Infringement is caused
by such combination; (iii) to the extent that the allegedly Infringing activity
continues after Stamps has provided EncrypTix modifications that would have
avoided the alleged Infringement; or (iv) to the extent that the alleged
Infringement is based on a United States patent [***]*.
                                                 ---

     (g) Limited Remedy. Without limiting the effect of Section 10(b) hereof, in
         --------------
no event shall EncrypTix have any right to recover from Stamps any amount
representing lost profits or lost business value of EncrypTix that might result
from (i) EncrypTix being precluded from using any of the Stamps Technology in
the Licensed Fields of Use because of conflicting proprietary rights of one or
more Third Parties or (ii) the invalidity of any of the Stamps Technology.

LIMITATIONS OF LIABILITY

                                 Schedule 8(b)

                        Expedited Arbitration Procedures
                        --------------------------------

The following procedures are applicable solely for an expedited confirmation for
a material breach of the Agreement for purposes of Section 8(b).

     1.   A party desiring to terminate the Agreement for a material breach (the
          "Terminating Party") by the other party shell deliver a Demand for
          Expedited Determination ("Demand") to each of the following:

          a.   The opposite party to the Agreement (the "Responding Party"), and

          b.   Each of the individuals identified on Attachment B to this
               Schedule (the "Pre-Approved Arbitrators").

     2.   The Demand shall be executed by the Terminating Party and shall:

          a.   State that the Terminating Party demands an expedited
               determination regarding whether the Responding Party has
               committed a material breach of the Agreement and that this
               expedited determination is to be made under Section 8 of the
               Agreement and pursuant to the procedures set forth in this
               Schedule 8(b),

          b.   Provide reasonable notice of the events and circumstances
               believed to amount to the material breach, and

          c.   Be accompanied by (i) a Notice to Pre-Approved Arbitrators (the
               "Notice") which shall include, without limitation, substantially
               the statements set forth on Attachment A to this Schedule and
               (ii) a copy of this Agreement and its Schedules.

     3.   A single arbitrator shall decide the matter, and that person shall be
          the "available" Pre-Approved Arbitrator (as "available" is defined in
          the Notice) listed highest on Attachment B to this Schedule who
          responds to the parties as provided and within the time stated in the
          Notice. The parties to this Agreement agree to pay (initially in equal
          amounts but subject to an award of fees and costs to the prevailing
          party as provided below) the normal or customary charges of the
          arbitrator, to advance promptly and in equal amounts an aggregate
          amount requested by the arbitrator as a retainer (which shall be
          refundable if and to the extent not used), to replenish such retainer
          as used to the extent such arbitrator may request, and to execute such
          reasonably customary submission agreement as the arbitrator may
          request.

     4.   The arbitrator shall convene a hearing to determine the following
          issue: whether the Terminating Party would be likely to prevail at a
          full trial on the merits on the claim that the Responding Party has
          committed a material breach of the Agreement. The determination of the
          arbitrator shall be based upon the evidence and argument presented
          during the hearings as well as any written briefs and evidence that
          may be submitted to him/her (and the adverse party) prior to the
          hearing. The arbitrator shall select a date or dates for the hearing
          that are no less than ten days and no more than 20 days after delivery
          of the Demand. The hearing shall last not more than two full days, and
          the parties shall split equally the time available to them for the
          presentation of evidence. The
<PAGE>

     arbitrator shall also state in writing whether he believes that the
     position of one party in and in connection with the arbitration was
     significantly more justified and correct than that of the other party. If
     so, the party identified as having had the more justified and correct
     position shall be deemed the "prevailing party," and the arbitrator's
     statement so identifying such party shall amount to an award of the
     reasonable costs and fees incurred by such party in connection with the
     arbitration, which shall be paid by the other party within thirty days
     after delivery to it of reasonable summary documentation thereof.

5.   No later than five (5) calendar days before the hearing, each party may
     deliver to the other party a request for immediate production of such
     documents and/or other evidence or information as the requesting party
     believes are readily available to the other party and are important for
     preparation or presentation at the hearing. The requested documents shall
     be produced three (3) days prior to the hearing. The failure of either
     party to produce such available materials as are so requested by the other
     party shall not be grounds for sanctions but may be taken into
     consideration by the arbitrator to the extent, if any, that he/she believes
     it relevant.

6.   Not later than twenty-four (24) hours before the hearing, each party may
     file with the arbitrator and serve on the adverse party a brief and any
     supporting evidence, including declarations or documentary materials.

7.   The arbitrator's decision shall not be admissible in evidence or disclosed
     in any judicial proceeding; provided, however, that this provision shall
     not apply to any notice of the claimed breach (which shall not include the
     Demand) nor any action taken to cure the claimed breach.

8.   To the extent they are consistent with the provisions of the Agreement
     (including this Schedule and its attachments), the arbitration shall be
     conducted under and pursuant to the Commercial Arbitration Rules of the AAA
     (the "AAA Rules") (but need not be administered by the AAA except as
     hereinafter provided). In the event that the procedures in this Schedule
     and the attachments hereto fail to produce an arbitrator able to proceed
     with the arbitration or fail in another respect(s) to permit the expedited
     determination to be made as contemplated in the Agreement, a single
     arbitrator shall be appointed by the AAA and the proceeding shall be
     conducted under the AAA Rules consistent, to the extent possible, with the
     provisions of this Schedule. (The parties shall request that the AAA select
     as the arbitrator a single person having experience in technology or
     technology licensing disputes or in disputes involving computer software.)
     The arbitration conducted by the AAA shall be for the limited purposes
     specified in paragraph 4 hereof and shall be decided within 30 days. Once
     an arbitrator is selected, the timing of the arbitration and the procedures
     for the arbitration shall be as specified in paragraphs 4 through 7 hereof.

9.   If the arbitrator determines that the Terminating Party would be likely to
     prevail at a full trial on the merits on the claim that the Responding
     Party committed a material breach of the Agreement, and if the breach is
     curable, the Responding Party may decide whether to cure the confirmed
     breach and, if it is and such party provides notice to the Terminating
     Party within two (2) business days after receipt of the arbitrator's
     decision that it has elected to effect such a cure, shall have thirty (30)
     calendar days from the decision of the arbitrator to cure the breach.

10.  If the arbitrator determines that there was a material breach of this
     Agreement, the parties hereby express their willingness to have the
     arbitrator comment upon and offer suggestions as to whether the breach is
     curable and, if so, how the cure may be effected. Any such statements,
     however, shall be non- binding and inadmissible for any purposes in any
     separate proceedings. In no event,

                                       2
<PAGE>

     absent the written consent of both parties, shall there be continuing
     proceedings or additional hearings before the arbitrator on the nature or
     adequacy of the cure.

These expedited procedures are intended to allow either party to the Agreement
to terminate the Agreement without undue delay in the event of a material breach
by the other party while giving the other party the benefit of an outside
person's review of the matter prior to the termination and, if the breach is
curable, an opportunity to cure. These procedures are intended to be summary in
nature and non-exclusive. A party believing that the opposite party has
committed a material breach may institute judicial proceedings (for damages
and/or for declaratory, equitable, and/or other relief): (a) at the same time as
utilizing these summary procedures or (b) after trying unsuccessfully to utilize
these procedures or having begun but not having completed use of these
procedures or (c) after and notwithstanding an adverse determination by the
arbitrator in an expedited arbitration under these procedures. The doctrines of
collateral estoppel and res judicata shall be inapplicable to the findings,
rulings, and all other aspects of these summary proceedings.
