OTHER PROVISIONS OF THIS AGREEMENT AND SHALL APPLY NOTWITHSTANDING THE FAILURE

9. INFRINGEMENT INDEMNITIES.

9.1 Exchange's Indemnity.

a. Indemnity. Except as provided below, Exchange shall defend
and indemnify VAR from and against any damages, liabilities, costs and expenses
(including reasonable attorneys' fees) finally awarded against VAR and arising
out of any claim that the Licensed Software infringes a valid United States
patent or copyright or misappropriates a trade secret of a third party;
provided, that (i) VAR shall have promptly provided Exchange written notice
thereof and reasonable cooperation, information, and assistance (at Exchange's
expense) in connection therewith, and (ii) Exchange shall have sole control and
authority with respect to the defense, settlement, or compromise thereof. If any
Licensed Software becomes or, in Exchange's opinion, is likely to become the

subject of any injunction preventing its use as contemplated herein, Exchange
may, at its option, (1) procure for the VAR (and End Users and Strategy
Affiliates) the right to continue using such Licensed Software, (2) replace or
modify such Licensed Software so that it becomes non-infringing without
substantially compromising its functionality, or, if (1) and (2) are not
reasonably available to Exchange, then (3) terminate VAR's Licenses and the
Sublicenses in respect of the allegedly infringing Licensed Software and pay to
VAR an amount not to exceed the depreciated value of the Licensed Software equal
to the license Fee paid by VAR for such Licensed Software depreciated on a
straight line basis over a three and one-half (3 1/2) year period. Exchange
shall have no obligation for any costs incurred by Licensee without Exchanges's
prior written authorization.

b. Exclusions. Exchange shall have no liability or obligation to
VAR hereunder with respect to any patent, copyright or trade secret infringement
claim based upon (i) use of the Licensed Software in an application or
environment or on a platform or with devices for which the Licensed Software was
not designed or contemplated, (ii) modifications, alterations, combinations or
enhancements of the Licensed Software not created or authorized by Exchange or
its authorized contractors or agents, (iii) use of a superseded version of the
Licensed Software if the infringement would have been avoided by using an Update
that Exchange provided to VAR; or (iv) any patent, copyright or trade secret in
which VAR (or any of its affiliates), or any End User or Strategy Affiliate, has
an interest. In accordance with Section 9.2, VAR shall indemnify and hold
Exchange harmless from all costs, damages and expenses (including reasonable
attorneys' fees) arising from any claim enumerated in clauses (i) through (iv)
above.

c. Entire Liability. The foregoing states the entire liability of
Exchange, and the sole and exclusive remedy of VAR, with respect to any claim of
infringement of patents, copyrights and trade secrets by the Licensed Software,
or any part thereof, or by its operation.

9.2 VAR's Indemnity.

a. Indemnity. VAR shall defend and indemnify Exchange from and
against any damages, liabilities, costs and expenses (including reasonable
attorneys' fees) arising out of any claim that any software, product or service
(including, but not limited to, any Value-Added Product) provided in connection
with any VAR System or the Service Bureau infringes a valid United States patent
or copyright or misappropriates a trade secret of a third party; provided, that
(i) Exchange shall have promptly provided VAR written notice thereof and
reasonable cooperation, information, and assistance (at VAR's expense) in
connection therewith, and (ii) VAR shall have sole control and authority with
respect to the defense, settlement, or compromise thereof.

b. Entire Liability. The foregoing states the entire liability of
VAR, and the sole and exclusive remedy of Exchange, with respect to any claim of
infringement of patents, copyrights and trade secrets by VAR's software,
products and services, or any part thereof, or by their operation.

9.3 Prompt Notice. The party seeking indemnification under this Section 9
will immediately inform the indemnifying party as soon as it becomes aware of
any threatened or actual liability claim by a third party. Any failure by the
party seeking indemnification under this Section 9 to promptly notify the
indemnifying party of a claim for which indemnification is sought, or to
cooperate in such claim, shall only relieve the indemnifying party of its
indemnity obligations hereunder to the extent that it is prejudiced by such
delay or failure to cooperate.

10. PROTECTION OF PROPRIETARY RIGHTS.

10. Definition. "Proprietary Materials" shall mean, with respect to
Exchange, all Licensed Software, Updates and enhancements, modifications and
translations thereof , with respect to VAR, all Value-Added Products, and with

repsect to both parties, any other information or data disclosed by either party
to the other, in written, graphic or machine readable form which by its nature
or type should reasonably be considered proprietary or confidential or which the
disclosing party labels as being proprietary or confidential. Each party
acknowledges that the other's Proprietary Materials are confidential and
constitute valuable assets of the discolosing party (or its third party
licensors). Proprietary Material does not include:

(i) Information which is or becomes available in the public domain
other than through disclosure by the receiving party (the
"Recipient") in breach of this Agreement);

(ii) Information disclosed or made available at any time to the
Recipient by a third party without breach of any relationship
of confidentiality to the disclosing party (the "Discloser");

(iii) Information independently developed by the Recipient without
use of the Proprietary Material of the Discloser;

(iv) Information which was already known to the Recipient, without
an obligation of confidentiality to the Discloser, at the time
of disclosure hereunder.

10.2 Confidentiality. Except for the specific rights granted by this
Agreement, Recipient shall not use, copy or disclose any Proprietary Material
without the written consent of the Discloser. Recipient shall hold all
Proprietary Materials in confidence, and use the highest commercially reasonable
degree of care to protect the Proprietary Materials, including at a minimum,
those precautions Recipient employs to protect its own confidential information,
but not less than a reasonable degree of care. Recipient shall not disclose the
Proprietary Materials except to its employees that have a need to know in
connection with Recipient's authorized uses under this Agreement and who have
agreed in writing not to disclose the Proprietary Materials. Recipient shall
bear the responsibility for any breaches of confidentiality by its employees.
Within ten (10) days after Discloser's request, and in its sole discretion,
Recipient shall either return to Discloser all originals and copies of any
Proprietary Materials and all information, records and materials developed
therefrom by Recipient, or destroy the same, other than such Proprietary
Materials as to which this Agreement expressly provides a continuing right to
Recipient to retain at the time of the request.

10.3 Proprietary Rights. Discloser (or its third party licensors) shall
retain all rights, title and interest in the Proprietary Materials, and
Recipient shall not take any action inconsistent with such title and ownership.
VAR, End Users and Strategy Affiliates shall not acquire any rights in
Exchange's Proprietary Materials, and Exchange shall not acquire any rights in
VAR's Proprietary Materials, except as express in this Agreement. VAR will keep
records of the number and location of all copies of Proprietary Materials and
make such records available to Exchange. Recipient shall not remove any
copyright or legal notices or proprietary rights notice included in any
Proprietary Material and shall reproduce all such notices on any copies of
Proprietary Material.

10.4 No Reverse Engineering. VAR shall not: (i) use any Licensed Software or
Documentation to create any software or documentation that is similar to or
competitive with any of the Licensed Software or Documentation; (ii) decompile,
disassemble, reverse compile, reverse assemble, reverse translate or otherwise
reverse engineer any Licensed Software, or use any similar means to discover the
source code of the Licensed Software or to discover the trade secrets therein,
or otherwise circumvent any technological measure that controls access to the
Licensed Software; or (iii) permit any third party to engage in any of the acts
proscribed in clauses (i) through (ii).

10.5 Notice. Recipient shall notify Discloser promptly of any unauthorized
possession, disclosure, or use of Proprietary Material or, in the case of VAR,
any violation of the confidentiality provisions included in any Sublicense
Agreement or Service Bureau Agreement of which VAR is aware. Recipient will take
such actions as Discloser may reasonably request (including instituting
appropriate legal proceedings) to enforce the confidentiality provisions of such
agreements and to prevent or remedy any further unauthorized possession,
disclosure or use of Proprietary Materials.

10.6 Remedies. Money damages will not be an adequate remedy if this Section
10 is breached and, therefore, Discloser shall, in addition to any other legal
or equitable remedies, be entitled to seek an injunction or similar equitable
relief against such breach or threatened breach without the necessity of posting
any bond.

11. TERM; TERMINATION

11.1 Term. This Agreement shall commence on the Effective Date and continue
for a period of three and one-half (3 1/2) years thereafter. This Agreement may
be renewed for an additional term of equal duration, upon the mutual written

11.2 Termination. Notwithstanding the foregoing, this Agreement may be
terminated:

materially breaches a provision of this Agreement and the breaching party fails
to cure such breach within thirty (30) days of the receipt of notice of such
breach from the non-breaching party.

b. Bankruptcy. By either party, immediately in the event any assignment
is made by the other party for the benefit of creditors, the party admits in
writing its inability to pay debts as they come due, or if a receiver, trustee
in bankruptcy or similar officer shall be appointed to take charge of any or all
of the other party's property, or if the other party files a voluntary petition
under federal bankruptcy laws or similar state statutes or such a petition is
filed against the other party and is not dismissed within sixty (60) days.

11.3 Effects of Termination. Upon termination of this Agreement for any
reason, all rights, obligations and licenses of the parties hereunder shall

extinguished by termination, and such amounts (if not otherwise due on an
earlier date) shall be immediately due and payable on the termination date.

use any Licensed Software (except to fulfill Sublicense orders outstanding as of

copies of the (i) Licensed Software, (ii) Documentation, (iii) other Proprietary
Materials in the possession or under the control of VAR and (iv) render unusable

(Nondisclosure), 13 (Compliance with Laws), 14 (General) and this Section 11
shall survive any termination or expiration of this Agreement.

11.4 Sublicenses. Notwithstanding any of the foregoing, any expiration
or termination of this Agreement shall not have an impact on those Sublicense
Agreements issued under this Agreement, and all terms and conditions of such
Sublicense Agreements shall continue in full force and effect.

12. NONDISCLOSURE. Without first obtaining the written consent of the other
party, neither party shall disclose the terms and conditions of this Agreement,
except as may be required to implement and enforce the terms of this Agreement,
or as may be required by legal procedures or by law. No other information
exchanged between the parties shall be deemed confidential unless the parties
otherwise agree in writing. VAR shall not disclose the results of benchmark
tests or the statistical performance results of any other evaluation of the
Licensed Software to any third party without Exchange's prior written approval.

13. Compliance with Laws.

13.1 Export. VAR shall not export or re-export, directly or indirectly
(including via remote access), Licensed Software, Documentation or other
information or materials provided by Exchange hereunder, to any country for
which the United States or any other relevant jurisdiction requires any export
license or other governmental approval at the time of export without first
obtaining such license or approval. It shall be VAR's responsibility to comply
with the latest United States export regulations, and VAR shall defend and
indemnify Exchange from and against any damages, fines, penalties, assessments,
liabilities, costs and expenses (including reasonable attorneys' fees and court
costs) arising out of any claim that Licensed Software, Documentation, or other
information or materials provided by Exchange hereunder were exported or
otherwise accessed, shipped or transported in violation of applicable laws and
regulations.

13.2 Compliance with Laws of Other Jurisdictions. VAR shall comply in all
material respects with all laws, legislation, rules, regulations, and
governmental requirements with respect to the Licensed Software, and the
performance by VAR of its obligations hereunder, of any jurisdiction in or from
which VAR directly or indirectly causes the Licensed Software to be used or
accessed. In the event that this Agreement is required to be registered with any
governmental authority, VAR shall cause such registration to be made and shall
bear any expense or tax payable in respect thereof.

14. GENERAL

14.1 Force Majeure. In the event that either party is prevented from
performing, or is unable to perform, any of its obligations under this Agreement
due to any cause beyond the reasonable control of the party invoking this
provision, the affected party's performance shall be extended for the period of
delay or inability to perform due to such occurrence.

14.2 Waiver. The waiver by either party of a breach or a default of any
provision of this Agreement by the other party shall not be construed as a
waiver of any succeeding breach of the same or any other provision, nor shall
any delay or omission on the part of either party to exercise or avail itself of
any right, power or privilege that it has, or may have hereunder, operate as a
waiver of any right, power or privilege by such party. No remedy referred to in
this Agreement is intended to be exclusive, but each shall be cumulative and in
addition to any other remedy referred to herein or otherwise available at law or
in equity.

14.3 No Agency; Independent Contractors. Nothing contained in this Agreement
shall be deemed to constitute either party as the agent or representative of the
other party, or both parties as joint venturers or partners for any purpose. VAR
shall have no authority to vary, alter or enlarge any of Exchange's obligations

hereunder or to make representations, warranties or guarantees on behalf of
Exchange. VAR shall make all agreements with End Users and Strategy Affiliates
in its own name and for its own account and risk, and shall establish its own
prices.

14.4 Governing Law; Jurisdiction & Venue. This Agreement shall be governed
by and construed in accordance with the laws of the State of New York, USA,
without regard to its choice of law provisions. In the event of any conflict
between foreign laws, rules and regulations and those of the United States, the
laws, rules and regulations of the United States shall govern. The United
Nations Convention on Contracts for the International Sale of Goods shall not
apply to this Agreement.

14.5 Entire Agreement; Amendment. This Agreement and the Appendices and
Exhibits attached hereto constitute the entire agreement between the parties
with regard to the subject matter hereof. No representation, promise, inducement
or statement of intention has been made by either party which is not set forth
in this Agreement and neither shall be bound by or liable for any alleged
representation, promise, inducement or statement of intention not so set forth.
No waiver, consent, modification or change of terms of this Agreement shall bind
either party unless in writing signed by both parties, and then such waiver,
consent, modification or change shall be effective only in the specific instance
and for the specific purpose given. Terms set forth in any purchase order of VAR
(or other similar document) that are in addition to or at variance with the
terms of this Agreement are specifically waived by VAR. All such terms are
considered by Exchange to be proposed material alterations of this Agreement and
are rejected. VAR's purchase order is only effective as VAR's unqualified
commitment to pay for a license to the Licensed Software upon the terms (and
only the terms) set forth herein.

14.6 Costs, Expenses and Attorneys' Fees. VAR shall reimburse Exchange for
all reasonable costs (including attorneys' fees) incurred by Exchange in
collecting late payments from VAR. If either party commences any action or
proceeding against the other party to enforce or interpret this Agreement, the
prevailing party in such action or proceeding shall be entitled to recover from
the other party the actual costs, expenses and attorneys' fees (including all
related costs and expenses), incurred by such prevailing party in connection
with such action or proceeding and in connection with obtaining and enforcing
any judgment or order thereby obtained.

14.7 Assignment. This Agreement, the Licenses and all of the other rights
and obligations hereunder, may not be assigned, in whole or in part by VAR,
without the prior written consent of Exchange. Any attempt by VAR to do so
without such consent shall be null and void ab initio. In the case of any
permitted assignment or transfer of or under this Agreement, this Agreement or
the relevant provisions shall be binding upon, and inure to the benefit of, the
successors, executors, heirs, representatives, administrators and assigns of the
parties hereto.

14.8 Notices. Any notice or communication from one party to the other shall
be in writing and either personally delivered or sent certified mail, postage
prepaid, return receipt requested, addressed to such other party at the address
specified in the first paragraph of this Agreement, or at such other address as
such party may from time to time designate in a notice to the other party. All
notices shall be in English and shall be effective upon receipt.

14.9 Non Solicitation. For the term of this Agreement and for a period of
twelve months after any expiration or termination of this Agreement, the parties
hereto do agree and affirm to refrain from any and all attempts to solicit or
recruit the employees of the other without the prior written approval of the
party whose employee is being considered for employment. This shall in no way,
however, be construed to restrict, limit or encumber the rights of any employee
granted by law.

14.10 Counterparts. This Agreement may be executed in multiple counterparts,
each of which shall be deemed an original, but all of which together shall

constitute one and the same instrument. In making proof of this Agreement, it
shall not be necessary to produce or account for more than one such counterpart.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their duly authorized officers or representatives as of the date
first written above.
