Taxes (excluding taxes on SAP's income or franchise taxes) and related costs,
interest and penalties paid or payable by SAP in connection with this Agreement,
provided Licensee will not be required to indemnify SAP or hold SAP harmless

other party from disclosure to third parties as with its own proprietary and
confidential information. Except as expressly authorized by this Agreement,
neither party shall, without the other party's prior written consent, disclose,
provide, or make available any of the Proprietary Information of the other party
in any form to any person, except to its bona fide employees, officers,
directors, or third parties whose access is necessary to enable the disclosing
party to exercise its rights hereunder. Each party agrees that prior to
disclosing any Proprietary Information of the other party to any third party, it
will obtain from that third party a written acknowledgment that such third party
will be bound by the same terms as specified in this Section 6 with respect to
the Proprietary Information and naming the other party as a third party
beneficiary. Use by a party of the other party's Proprietary Information shall
in any event be solely for the purposes of this Agreement.

         6.3 Modifications and Extensions.

         (a) Licensee may make Modifications and Extensions to the Software,
other than third party software, for Use on the Designated Unit(s) under the
terms set forth in this section. Licensee shall register all Modifications to
the Software with SAP prior to making such Modifications. Licensee agrees to
insert in all copies of the Software as modified all copyright, trade secret, or
other notices thereon or therein as SAP may from time to time direct.

         (b) In the event Licensee without SAP's participation develops any
Modification or Extension (hereinafter referred to as "Licensee Extension" or
"Licensee Modification") to the Software, Licensee shall have all rights, title,
and interest in such Licensee Modification or Licensee Extension subject to
SAP's rights in the Software. Licensee agrees to offer SAP the first right to
negotiate a license to or assignment of such Licensee Modification or Licensee
Extension and the parties agree to negotiate such rights in good faith. Licensee
agrees that prior to SAP's termination or waiver of its first right to
negotiate, such Licensee Modification or Licensee Extension will be used solely
in connection with the business operations of Licensee and its Affiliates, and
that such Licensee Modification or Licensee Extension will not be marketed,
licensed or sublicensed, sold, assigned, or otherwise transferred or made
available to any third party or other entity.

         All notices concerning the SAP's first right to negotiate shall be
provided in writing to the attention of SAP's Vice President, Solutions and
Partner Support, Assistant General Counsel, and the Licensee's Chief Financial
Officer. Should Licensee desire to initiate such negotiation, Licensee shall
provide to SAP all documentation and material pertaining to such Licensee
Modification or Licensee Extension reasonably necessary to permit SAP to
determine if it desires to exercise its right to negotiate. SAP shall advise
Licensee of its decision in writing within one hundred and eighty (180) days
after receipt of all such information. In the event SAP declines, in writing, or
fails to exercise its right to negotiate, within the one hundred and eighty
(180) day period, Licensee shall be free to enter into an Agreement with a third
party. Licensee agrees that prior to the passing of one hundred and eighty (180)
days or SAP's waiver of its first right to negotiate, such Licensee Modification
or Licensee Extension will be used solely in connection with the business
operations of Licensee and its Affiliates, and that such Licensee Modification
or Licensee Extension will not be marketed, licensed, or sublicensed, sold,
assigned, or otherwise transferred or made available to any third party.

         (c) In the event SAP develops either independently, or jointly with
Licensee, any Modification or Extension to the licensed Software, such
Modification or Extensions and all rights associated therewith will be the
exclusive property of SAP and SAP AG, and Licensee will not grant, either
expressly or impliedly, any rights, title, interest, or licenses to such
Modifications or Extensions to any third party. Licensee shall be entitled to
Use such Modifications and Extensions developed for or with Licensee on the
Designated Unit(s) under the terms set forth in this Agreement. Licensee agrees
to assign all right, title and interest in and to jointly developed
Modifications and Extensions to SAP. Licensee agrees to execute, acknowledge and
deliver to SAP all documents and do all things necessary, at SAP's expense, to
enable SAP to obtain and secure such Modifications or Extensions throughout the
world. Licensee agrees to secure the necessary rights and obligations from
relevant employees, or third parties in order to satisfy the above obligations.

         (d) The parties hereto agree that the granting of any rights, title, or
interest to Licensee in any Modification or Extension shall not be construed by
the parties hereto, any court of law or equity, or any arbitration panel to mean
that SAP has granted or given up any rights, title, or interest in or to the SAP
Proprietary Information.

7.       PERFORMANCE WARRANTY.

         7.1 Warranty Period; Warranty. SAP warrants that the Software will in
all material respects conform to the functional specifications contained in the
Documentation for six months following Delivery (the "Warranty Period") when
Used without material alteration on the Designated Unit(s). SAP's warranty is
subject to Licensee providing SAP necessary access, including remote access, to
the Software. Licensee shall provide SAP with sufficient test time and support
on Licensee's Designated Unit(s) to correct any reported defect.

         7.2 Scope of Warranty.

         (a) The warranty set forth in this Section 7 shall not apply: (i) if
the Software is not used in accordance with the Documentation; or (ii) to any
Extensions or Modifications; or (iii) if the defect is caused by: a Modification
or Extension, Licensee, or a third-party software malfunction.

         (b) SAP does not warrant that the Software will operate uninterrupted
or that it will be free from minor defects or errors which do not materially
affect such performance or that the applications contained in the Software are
designed to meet all of Licensee's or its authorized Affiliates' business
requirements.

         7.3 Express Disclaimer. EXCEPT AS SET FORTH IN THIS AGREEMENT, SAP AND
ITS LICENSORS DISCLAIM, WITH RESPECT TO THIS AGREEMENT, ALL OTHER WARRANTIES
EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE EXCEPT TO THE EXTENT THAT
ANY WARRANTIES IMPLIED BY LAW CANNOT BE VALIDLY WAIVED.

8.       INDEMNIFICATION.

         8.1 SAP Representation. SAP represents that its licensors own the
Proprietary Information licensed by SAP hereunder, including all intellectual
property rights therein, and that SAP has all rights necessary to license, in
accordance with the terms of this Agreement, such Proprietary Information to
Licensee, and to otherwise perform its obligations under this Agreement.

         8.2 No Representation Regarding Combination Use. SAP and its licensors
make no representation with respect to the possibility of infringement by
Combination Use of the Software. The parties agree that SAP has no duty to
investigate nor to warn Licensee of any such possibility. "Combination Use"
means Use of the Software in conjunction with any of the following, unless such
Use is prescribed in the Documentation: (i) any software other than the Software
and Third Party Database Software; (ii) any apparatus other than a Designated
Unit; and/or (iii) any activities of Licensee or its authorized Affiliates not
licensed under this Agreement.

         8.3 Indemnification of Licensee. Except for Combination Use, SAP shall
indemnify Licensee against all claims, liabilities, and costs, including
reasonable attorneys' fees, reasonably incurred in connection with any claim
brought against Licensee in the Territory by third parties alleging that
Licensee's Use of the Software, Documentation and other SAP Proprietary
Information, excluding the Third Party Database Software and PTS On-Demand
Personal Navigation Software, and any other third party software that may be
licensed, infringes, misappropriates or creates, as applicable: (i) any United
States, Canadian, German or European Union patent; or (ii) a copyright; or (iii)
trade secret rights; or (iv) a trademark; or (v) unfair competition, provided
that, Licensee promptly notifies SAP in writing of any such claim and SAP is
permitted to control fully the defense, unless there is a conflict between SAP's
and Licensee's interests wherein Licensee shall have the ability to control its
own defense, and any settlement of such claim as long as such settlement shall
not include a financial obligation on Licensee. Licensee's failure to provide
the aforementioned prompt notice shall not excuse SAP's obligations to indemnify
Licensee hereunder unless such failure prejudices SAP's ability to indemnify
Licensee in accord with this Section 8. Licensee shall cooperate fully, at SAP's
expense, in the defense of such claim, and may appear, at its own expense,
through counsel reasonably acceptable to SAP, unless there is a conflict between
SAP's and Licensee's interests wherein Licensee shall have the ability to
control its own defense, at SAP's expense. SAP may, in its sole discretion,
settle any such claim on a basis requiring SAP to (i) substitute for the
Software or Documentation or other SAP Proprietary Information, excluding the
Third Party Database Software, PTS On-Demand Personal Navigation Software, and
any other third party software that may be licensed, alternative substantially
equivalent non-infringing programs and supporting documentation; or (ii) obtain
the right for continued use of the Software or Documentation or other SAP
Proprietary Information, excluding the Third Party Database Software, PTS
On-Demand Personal Navigation Software, and any other third party software that
may be licensed, that is the subject of the claim; or (iii) modify the
infringing Software or Documentation or other SAP Proprietary Information,
excluding the Third Party Database Software, PTS On-Demand Personal Navigation
Software, and any other third party software that may be licensed, to avoid the
claimed infringement, while maintaining at least equivalent functionality.

         In the event that any preliminary injunction, temporary restraining
order or final injunction shall be obtained in the Territory restricting
Licensee's Use of the Software or Documentation or other SAP Proprietary
Information, excluding the Third Party Database Software, PTS On-Demand Personal
Navigation Software, and any other third party software that may be licensed,
SAP shall, at its sole option, either:

         (a) obtain the right for continued use of the Infringing Software or
Documentation or other SAP Proprietary Information, excluding the Third Party
Database Software, PTS On-Demand Personal Navigation Software, and any other
third party software that may be licensed; or

         (b) modify the infringing Software or Documentation or other SAP
Proprietary Information, excluding the Third Party Database Software, PTS
On-Demand Personal Navigation Software, and any other third party software that
may be licensed to avoid such infringement while obtaining at least equivalent
functionality; or

         (c) substitute for the Software or Documentation or other SAP
Proprietary Information, excluding the Third Party Database Software, PTS
On-Demand Personal Navigation Software, and any other third party software that
may be licensed alternative equivalent software and supporting documentation; or

         (d) after using best efforts to provide (a), (b), or (c) above, provide
a refund to Licensee of paid license fees for that part of the Software or
Documentation or other SAP Proprietary Information, excluding the Third Party
Database Software, PTS On-Demand Personal Navigation Software, and any other
third party software that may be licensed under claim of infringement, (unless
such part is a major integral function of the Software, in which case a full
refund of paid license fees would be reimbursable). All such refunds shall be
depreciated on a five (5) year straight line basis.

         8.4 SAP's Right to Commence Infringement Actions. SAP alone shall be
responsible for taking such actions which it determines are reasonably necessary
or desirable in its sole discretion in connection with any infringement or
alleged infringement by a third party of any portion of the Software and
Documentation. Licensee shall not undertake any action in response to any
infringement or alleged infringement of the Software and Documentation without
the prior written consent of SAP, which consent shall not be unreasonably
withheld. Licensee agrees to cooperate with and assist SAP, at SAP's expense, by
taking whatever action which SAP determines to be reasonably necessary or
desirable in connection with such defense. SAP agrees to reimburse Licensee for
reasonable legal fees and other expenses incurred in connection with any such
claim, suit, damage, or loss.

         8.5 SAP's Duty to Indemnify Licensee. THE PROVISIONS OF THIS SECTION 8
STATE THE SOLE, EXCLUSIVE, AND ENTIRE LIABILITY OF SAP AND ITS LICENSORS TO
LICENSEE, AND IS LICENSEE'S SOLE REMEDY, WITH RESPECT TO THE INFRINGEMENT OF
THIRD-PARTY INTELLECTUAL PROPERTY RIGHTS.

installation of the Software. THE SOFTWARE IS NOT SPECIFICALLY DEVELOPED OR
LICENSED HEREUNDER FOR USE IN ANY DIRECT AND ACTIVE OPERATIONS OF ANY EQUIPMENT
IN ANY NUCLEAR, AVIATION, MASS TRANSIT, OR MEDICAL APPLICATIONS, OR IN ANY OTHER
INHERENTLY DANGEROUS APPLICATIONS. THE PARTIES HERETO AGREE THAT USE OF THE

         9.3 Limitation of Liability. ANYTHING TO THE CONTRARY HEREIN
NOTWITHSTANDING, EXCEPT FOR DAMAGES RESULTING FROM UNAUTHORIZED USE OR
DISCLOSURE OF THE PROPRIETARY INFORMATION, UNDER NO CIRCUMSTANCES SHALL SAP, ITS

PATENT, COPYRIGHT, TRADE SECRET RIGHT, TRADEMARK OR CLAIM OF UNFAIR COMPETITION)
OR BE LIABLE IN ANY AMOUNT FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL, OR INDIRECT
DAMAGES, LOSS OF GOOD WILL OR BUSINESS PROFITS, WORK STOPPAGE, DATA LOSS,
COMPUTER FAILURE OR MALFUNCTION, OR EXEMPLARY OR PUNITIVE DAMAGES. The
provisions of the Agreement allocate the risks between SAP and Licensee. The
License Fees reflect this allocation of risk and the limitations of liability
herein.

<PAGE>   13


DAMAGES IS INTENDED BY THE PARTIES TO BE SEVERABLE AND INDEPENDENT OF ANY OTHER
PROVISION AND TO BE ENFORCED AS SUCH.

10.      ASSIGNMENT.

         Licensee may not, without SAP's prior written consent, assign,
delegate, sublicense, pledge, or otherwise transfer this Agreement, except as
specifically authorized in Section 2.2 of this Agreement, or any of its rights
or obligations under this Agreement, or the SAP Proprietary Information, to any
party, including any Affiliate. Any permitted assignment of this Agreement shall
provide that the provisions of this Agreement shall continue in full force and
effect and that Licensee shall guaranty the performance of its assignee and
shall remain liable for all obligations hereunder. SAP may assign this Agreement
to SAP America, Inc. or SAP AG. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
permitted assigns.

         Notwithstanding the foregoing, Licensee shall have the right to assign
this Agreement (excluding all third-party software) to any entity which acquires
all or substantially all of Licensee's operating assets, or, in the event
Licensee is merged or reorganized pursuant to any plan of merger or
reorganization, subject to the condition that Licensee provides SAP with: (1) a
statement, signed on behalf of the Assignee, that such Assignee agrees to abide
by the terms of this Agreement; (2) evidence, satisfactory to SAP, of such
Assignee's corporate authority to enter into this Agreement; and (3) financial
information showing that such Assignee has a minimum net worth, sufficient in
SAP'S reasonable judgment, to allow Assignee to perform its obligations under
this Agreement.

11.      GENERAL PROVISIONS.

         11.1 Rights to Injunctive Relief. Both parties acknowledge that
remedies at law may be inadequate to provide SAP or Licensee with full
compensation in the event of Licensee's material breach of Sections 2, 6, 10 or
11.5, or SAP's material breach of Section 6 with respect to Licensee Proprietary
Information, and that the non-breaching party shall therefore be entitled to
seek injunctive relief in the event of any such material breach.

         11.2 Severability. If any provision of this Agreement is determined to
be invalid or unenforceable, it will be deemed to be modified to the minimum
extent necessary to be valid and enforceable. If it cannot be so modified, it
will be deleted and the deletion will not affect the validity or enforceability
of any other provision unless, as a result, the rights of either party are
materially diminished or the obligations and burdens of either party are
materially increased so as to be unjust or inequitable.

         11.3 No Waiver. If either party should waive any breach of any
provision of this Agreement, it shall not thereby be deemed to have waived any
preceding or succeeding breach of the same or any other provision hereof.


SAP CONFIDENTIAL                       13

         11.4 Counterparts. This Agreement may be signed in two counterparts,
each of which shall be deemed an original and which shall together constitute
one Agreement.

         11.5 Export Control Notice. Regardless of any disclosure made by
Licensee to SAP of an ultimate destination of the Software, Documentation,
Third-Party Database Software, and other provided SAP Proprietary Information
Licensee acknowledges that the Software, Documentation, Proprietary Information,
and the Third-Party Database Software are being released or transferred to
Licensee in the United States and are therefore subject to the U.S. export
control laws. Licensee acknowledges its exclusive obligation to ensure that its
exports from the United States are in compliance with the U.S. export control
laws. Licensee shall also be responsible for complying with all applicable
governmental regulations of any foreign countries with respect to the use of the
Proprietary Information by its Affiliates outside of the United States. Licensee
agrees that it will not submit the Software to any government agency for
licensing consideration or other regulatory approval without the prior written
consent of SAP. Licensee shall defend, indemnify, and hold SAP and is licensors
harmless from and against any and all claims, judgments, awards, and costs
(including reasonable legal fees) arising out of Licensee's noncompliance with
applicable U.S. or foreign law with respect to the use or transfer of the SAP
Proprietary Information outside the United States by Licensee and its
Affiliates.

         11.6 Confidential Terms and Conditions. Licensee shall not disclose the
terms and conditions of this Agreement, except as required by law including
without limitation applicable securities laws, and the pricing contained therein
to any third-party. Neither party shall use the name of the other party in
publicity, advertising, or similar activity, without the prior written consent
of the other, except that both parties consent to the other's inclusion of its
name in customer or provider listings, as appropriate, which may be published as
part of a party's marketing efforts.

         11.7 Governing Law. This Agreement shall be governed by and construed
under the Commonwealth of Virginia law without reference to its conflicts of law
principles. In the event of any conflicts between foreign law, rules, and
regulations, and United States of America law, rules, and regulations, United
States of America law, rules, and regulations shall prevail and govern. The
United Nations Convention on Contracts for the International Sale of Goods shall
not apply to this agreement.

         11.8 Escrow of Source Code.

         1. SAP warrants that the source code for the Software, together with
related Documentation as it is or becomes available, has been deposited in an
escrow account maintained at Data Securities International Inc., Burlington, MA

         2. SAP will from time to time deposit into the escrow account copies of
source code for Releases and Versions of the Software and related Documentation.

         (a) The existence of any one or more of the following circumstances,
uncorrected for more than thirty (30) days: entry of an order for relief under
Title 11 of the United States Code; the making by SAP of a general assignment
for the benefit of creditors; the appointment of a general receiver or trustee
in bankruptcy of SAP's business or property; or action by SAP under any state
insolvency or similar law for the purpose of its bankruptcy, reorganization, or
liquidation; unless within the specified thirty (30) day period, SAP (including
its receiver or trustee in bankruptcy) provides to Licensee adequate assurances,
reasonably acceptable to Licensee, of its continuing ability and willingness to
fulfill its maintenance obligations under this Agreement;

         (b) SAP has ceased its on-going business operations or that portion of
its business operations relating to the sale, licensing and maintenance of the
Software; or

         (c) Failure of SAP to carry out the material maintenance obligations,
by termination of maintenance services by SAP or otherwise, imposed on it
pursuant to this Agreement after reasonable opportunity has been provided to SAP
America, Inc. and SAP AG to perform such obligations.

         4. In no event shall Licensee have the right to access the applicable
deposited materials if SAP America, Inc. or SAP AG perform SAP's maintenance
obligations under this Agreement.

         5. In the event of release under this Agreement, Licensee agrees that
it will treat and preserve the deposited materials as a trade secret of SAP AG
in accordance with the same precautions adopted by Licensee to safeguard its own
trade secrets against unauthorized use and disclosure and in all cases at least
with a reasonable degree of care. Release under this provision shall not extend
Licensee any greater rights or lesser obligations than are otherwise provided or
Imposed under this Agreement. This provision shall survive any termination of
this Agreement.

         11.10 Force Majeure. Any delay or nonperformance of any provision of
this Agreement (other than for the payment of amounts due hereunder) caused by
conditions beyond the reasonable control of the performing party shall not

provision, if any, shall be deemed to be extended for a period equal to the
duration of the conditions preventing performance.
