policy of comprehensive general public liability (including coverage for bodily
injury, property damage, personal injury (employee and contractual liability
exclusions deleted), contractual liability, owner's protective liability and
broad form property damage) with (a) Tenant named as the insured thereunder and
(b) Landlord and any mortgagee (of which Landlord shall give Tenant notice)
named as additional insureds thereunder. Such insurance shall include coverage
for Tenant's indemnification obligations hereunder. The minimum limits of
liability under such policy shall be a combined single limit of not less than
Two Million Dollars ($2,000,000.00) with respect to each occurrence. Such

claims arising during the entire Term of this Agreement, regardless of when such
claims are made, either by obtaining an endorsement providing for an unlimited
extended reporting period in the event such policy is canceled or not renewed
for any reason whatsoever, or by obtaining new coverage with a retroactive date
the same as or earlier than the expiration date of the canceled or expired
policy. The limits of such insurance shall not, under any circumstances, limit
the liability of Tenant hereunder. Tenant, on its behalf and on behalf of its
insurer, hereby waives all rights of subrogation with respect to Landlord.

         11. TERMINATION. In addition to any and all other rights or remedies
provided in this Agreement or which Landlord may have at law, in equity, or
otherwise, in the event that Tenant fails to comply with any obligations imposed
upon Tenant hereunder, Landlord will have the right, after three (3) days'
notice to Tenant of any such non compliance and Tenant's failure to remedy same
within such period (or if such non compliance cannot be remedied within such
three (3) day period, Tenant's failure to commence a cure within such period and
diligently thereafter pursue such cure to completion), to terminate this
Agreement on the date specified by Landlord in such notice, and Tenant will
immediately quit and surrender the Premises as required hereby.

         12. ASSIGNMENT/OCCUPANCY. Tenant will not assign or sub lease its
rights or delegate its duties under this Agreement (whether by operation of law,
transfer of interest in Tenant or otherwise) or permit the Premises or any part
thereof to be occupied or used by any other person or entity.

         13. WAIVER OF TRIAL BY JURY. Tenant will and hereby waives trial by
jury in any action, proceeding or counterclaim brought by either of Tenant or
Landlord against the other on any matters whatsoever arising out of, or in any
way connected with, this Agreement. If Landlord commences any summary proceeding
against Tenant, Tenant will not interpose any counterclaim of whatever nature or
description in any such proceeding. Moreover, Tenant will not seek to
consolidate such proceeding with any other action, which may have been or may be
brought in any other court by Tenant.

         14. ACCESS. Landlord and its agents will have the right, from time to
time throughout the Term, to enter any portion of the Premises to examine the
same, to show the same to prospective purchasers, mortgagees or tenants of the
Building or any space therein, and to make such repairs, alterations,
improvements or additions as Landlord may deem necessary or desirable to the
Premises (or any other portion of the Building), including, but not limited to,
pipes, conduits and structural modifications, or to make repairs or perform any
work which Tenant is obligated to make or perform under this Agreement, at
Tenant's sole cost and expense, which Landlord is entitled to make or may elect
to perform following Tenant's failure to so repair or perform. None of the
foregoing shall give rise to any liability on the part of Landlord. Any work
performed or inspections or installations made pursuant to this Section shall be
made with reasonable diligence and in a manner designed to minimize interference
with Tenant's use of the Premises; provided, however, that Landlord will not be
obligated to employ contractors or labor at overtime or other premium pay rates
or incur any other overtime costs or expenses whatsoever.

         15. EXPIRATION OF THE AGREEMENT. Upon the expiration or earlier
termination of the Term of this Agreement, Tenant will quit and surrender the
Premises to Landlord vacant, broom clean, in good order and condition, ordinary
wear and tear excepted, and Tenant will remove all of its property therefrom.
Tenant acknowledges that possession of the Premises must be surrendered to
Landlord upon the expiration or earlier termination of this Agreement. The
provisions of this Section will survive the expiration or earlier termination of
the Term of this Agreement. If Tenant fails to fulfill its obligations under
this Section, Landlord shall have the right, in its sole discretion and without
prejudice to any other remedy it may have under this Agreement or at law, or so
much thereof as necessary, to satisfy Tenant's obligations under this Section at
Tenant's sole cost and expense.

         16. LIMITATION OF LIABILITY. Landlord's obligations under this
Agreement will not be binding upon Landlord after the sale, conveyance,
assignment or transfer by Landlord of its interest in the Building and in the
event of any such sale, conveyance, assignment or transfer, Landlord will be and
hereby is entirely freed and relieved of all covenants and obligations of
Landlord hereunder to the extent that such transferee assumes Landlord's
obligations under this Agreement, subject to the terms hereof. None of the
Landlord Parties (as defined in Section 24) will be liable for the performance
of Landlord's obligations under this Agreement. Tenant will look solely to
Landlord to enforce Landlord's obligations hereunder and will not seek any
damages against any of the Landlord Parties. Prior to any such sale, conveyance,
assignment or transfer, Landlord's liability for its obligations under this
Agreement will be limited to Landlord's equity interest in the Building and
Tenant will not look to any other property or assets

                                       6
<PAGE>

of Landlord or any of the Landlord Parties in seeking either to enforce

Landlord's failure to perform such obligations.

loss, cost, damage, expense and liability (including, without limitation, court

obligations; nor shall they supersede any inconsistent agreement of the parties
set forth in any other provision of this Agreement. The provisions of this
Section shall survive the expiration or sooner termination of this Agreement
with respect to any claims or liability occurring prior to such expiration or
termination.

         those fees to which Licensor is entitled within thirty (30) days after
         payment by the End-User. Unless otherwise stated herein, the parties
         agree that the party who receives a payment from an End-User for any
         fees described in Appendix A ("Receiving Party") shall pay the other
         party the other's share, as determined by this Agreement, of such fees
         within thirty (30) days of the Receiving Party's receipt of such fees

                            MISCELLANEOUS PROVISIONS

5.1      DELIVERY AND TITLE. The Software and Documentation shall at all times
         remain the sole and absolute property of the Licensor.

5.2      UPDATES. Licensor intends to provide Upgrades to the Software and
         Documentation as reasonably required to address issues and problems
         brought to its attention by the End-Users or the Licensee. An End-User
         will only be entitled to Updates if the End-User has entered into a
         Maintenance Agreement with Licensor and the End-User has satisfied all
         of it its payment obligations under the Maintenance Agreement. The
         timing of the Updates will be defined by the magnitude of the problem.
         Material defects will be addressed immediately and will receive the
         highest priority for coding, testing, and support resources.

5.3      UPGRADES. Licensor intends to provide Upgrades to the Software and
         Documentation in scheduled releases. These releases will be made
         available to Licensee with sufficient time for testing prior to their
         availability to the End-Users The Upgrades will be based in part on
         requests made by the End-Users and the Licensee. The Licensor
         recognizes the importance of these enhancements and will make its best
         effort to comply with all reasonable requests. Licensor retains the
         right to refuse any request that it feels would detract from the
         product's overall functionality or supportability.

5.4      SOFTWARE. Though it is desirable to maintain only one version of
         Software, it is unrealistic to assume that every installation will be
         identical. Therefore, one version will be maintained as the base
         Software and modifications will be applied to create the custom
         applications required by the market. The Licensor will maintain a copy
         of each version installed in the field for ongoing support. Given the
         number of potential versions, the Licensor will offer maintenance on
         customized versions for a period of three (3) years from the date of
         installation at an additional expense to the End-User. This maintenance
         expense will be negotiated between the Licensor and the End-User.
         Upgrades may be required due to releases of PEP+. The Licensee is
         required to evaluate the impact to the Software and Documentation with
         respect to information regarding the integration of the Software with
         PEP+, but it is the ultimate responsibility of the Licensor to keep the
         Documentation accurate and up to date. The Licensor will make all
         reasonable changes required by the modifications to PEP+ and coordinate
         their testing and implementation with the Licensee.

5.5      DOCUMENTATION. Within a reasonable time following completion of the
         standard documentation for a New Product to which Licensee has
         exercised its Option, but in no event later than thirty (30) days prior
         to the General Availability of such New Product, Licensor shall provide
         Licensee at least one (1) copy of all standard documentation relating
         to that New Product Within thirty (30) days of receipt of the
         documentation, Licensee may request revisions and/or additions to the
         documentation. Licensor has the sole discretion to accept and/or
         implement Licensee's proposed revisions or additions. However, if the
         documentation is, in Licensee's reasonable opinion, not sufficient to
         license the corresponding New Product, then Licensee may elect to not
         sell the corresponding New Product by notifying Licensor of such
         election in writing within later of thirty (30) days of Licensee's
         receipt of original or revised documentation. If no revisions and/or
         additions are requested or no written notification of election as made
         in response to receiving the original or revised documentation, the
         documentation will be deemed accepted by Licensee. If Licensee elects
         not to sell the corresponding New Product, Licensee tray subsequently
         elect to sell the corresponding New Product at any time during the term
         of this Agreement by notifying Licensor in writing. For the time period
         that Licensee elects not to sell the corresponding New Product,
         paragraph 2.2 will have no force or effect.

         Licensee may request revisions and/or additions to such Documentation
         and the parties agree to work in good faith and at no cost to the other
         party to implement such reasonable requests for revisions and/or
         additions. In no event is Licensor required to accept and/or implement
         Licensee's requested revisions and/or additions to such Documentation.

         support.

5.7      MAINTENANCE. Primarily maintenance will be accomplished through Updates
         to the Software in an orderly and coordinated methodology. There may
         exist, from time to time, a need to make immediate modifications to an
         End-User's customized Software in order to correct problems to meet
         daily or monthly production schedules. In these circumstances, Licensor
         will make any/all changes required to put the customized Software back
         into production. These "fixes" are temporary in nature and are intended
         to be replaced through the Update process.

         Licensee shall not be responsible for providing any maintenance and
         shall not share in any maintenance revenues, unless indicated in
         Appendix A. Licensor shall provide all required maintenance and shall
         receive all maintenance revenues as described in Appendix A. The
         parties agree that Licensor shall be permitted to enter into
         Maintenance Agreements with End Users.

5.7.1    MAINTENANCE AGREEMENTS FOR PROSPECTIVE AND CURRENT END-USERS. Licensee
         agrees to present Licensor's standard Maintenance Agreement at the same
         time Licensee presents the Sublicense to prospective End-Users and to
         use its best efforts to obtain each prospective End-User's agreement to
         said Maintenance Agreement contemporaneous with obtaining each
         prospective End-User's agreement to the Sublicense.

         In addition, subsequent to the Effective Date and contemporaneous with
         the next renewal of any maintenance agreement between Licensee and each
         End-User existing as of the Effective Date, Licensee agrees to present
         Licensor's standard Maintenance Agreement to each such End-User.
         Moreover, Licensee shall use its best efforts to obtain such End-Users'
         agreement to said Maintenance Agreement, which shall include, without
         limitation, Licensee offering a reduced maintenance fee to such
         End-User(s) (reduced by the dollar amount Licensor will charge such
         End-User per the terms of Licensor's standard Maintenance Agreement for
         maintenance on the Software) and in conjunction with Licensee's
         presentation of Licensor's standard Maintenance Agreement to such
         End-User(s). The dollar amount Licensor shall charge such End-Users
         shall be calculated in accordance with Appendix A. Unless otherwise
         stated herein or agreed to by the parties, subsequent to the Effective
         Date, Licensee shall have no obligation to collect and remit to
         Licensor any Annual Maintenance fees.

         Notwithstanding the proceeding, as to End-Users existing as of the
         Effective Date who pay Licensee a maintenance fee based on the volume
         of transactions such End-Users process through Licensee's software
         ("Volume Eased End User"), Licensee shall use its best efforts to
         obtain from such Volume Based End-Users agreement to Licensor's
         standard Maintenance Agreement. Such standard Maintenance Agreements
         shall state that Licensor will not directly charge Volume Based
         End-Users for performing such maintenance and shall be presented by
         Licensee to such Volume Based End-Users contemporaneously with the next
         renewal of a maintenance agreement between Licensee and such Volume
         Based End-User(s). As a result, Licensee agrees to continue to collect
         and distribute to Licensor the Annual Maintenance fees as described in
         Appendix A for such Volume Based End-Users within thirty (30) days of
         Licensee's receipt of such fees.

         Licensee further agrees that all End-Users' agreement to Licensor's
         standard Maintenance Agreement shall be a condition precedent to any
         End-User's implementation of the Software.

         EXISTING AS OF THE EFFECTIVE DATE. The parties further acknowledge and
         agree that within thirty (30) days from the Effective Date, Licensee
         shall pay Licensor the amounts listed in Appendix B for all maintenance
         and license fees that have not already been remitted to Licensor and
         were due or collected by

                                       6

         Licensee in connection with all agreements for Software entered into by
         Licensee prior to the Effective Date ("Past Fees"). Licensee warrants
         that said amounts listed in Appendix B represent all of the Past Fees.
         Payment of the amounts listed on Appendix B shall constitute full and
         complete satisfaction of any and all maintenance and license fees owed

         End-User for purposes of, including, but not limited to, providing
         maintenance and obtaining maintenance fees.

         so by End-User, perform Consulting Services and Custom Code services
         for the End-User. Payment for those services shall be determined by the
         terms in section 4, ET SEQ herein and Appendix A attached hereto.

5.9      During the term of this Agreement and for a period of twelve (12)
         months thereafter, neither party shall solicit for employment (either
         as an employee or contractor) any of the other party's employees who
         performed any services related to this Agreement.

                                   SECTION 6

         least as protective as the precautions it uses to protect its own
         propriety computer programs, to protect the Software and Documentation
         from unauthorized copying, use, or disclosure. Licensee shall allow
         access to the Software and Documentation only to employees and
         contractors who are performing services for Licensee related to the
         purposes of the Agreement and who "need to know" the information
         contained in the Software and Documentation, and upon whom, both
         parties have imposed a legal duty to protect the Software and
         Documentation from unauthorized copying, use, or disclosure. Both
         parties agree to use their best efforts to prevent, prosecute, and
         enjoin any actual or threatened unauthorized copying, use, or
         disclosure of the Software and Documentation. Licensor agrees that it
         shall under take the same precautions identified above with respect to
         the Licensee's software, documentation, and other Confidential
         Information it gains access to through the relationship set forth
         herein.

6.2      CONTRACTS. Each party shall use its best efforts, to prevent,
         prosecute, and enjoin any unauthorized copying, distribution, reverse
         engineering, and reverse compiling of the Software, Documentation
         and/or PEP+, through appropriate restrictive contracts entered into by
         its employees, consultants, and other third parties having access
         thereto, and through the use of the Sublicenses with End-Users, and
         shall pursue appropriate actions to enforce such protection provisions.

         any determination, discovery, or notification that any person or entity

         protection or defense of any Intellectual Property Rights pertaining to
         the Software without the prior written approval of Licensor, provided
         that such inaction will not prejudice the protection or defense of any
         Intellectual Property Rights pertaining to the Software. Licensee's
         failure to provide such notice shall not lessen or otherwise diminish
         Licensor's indemnification obligations set forth herein.

         any claim to the extent such claim: (i) is based upon the combination,

         Documentation or by Licensor, or (ii) is based upon any alteration or
         modification of the Software not made by Licensor or its agents or
         subcontractor's, or is not authorized by Licensor or described in the
         applicable documentation.

9.6      INDEMNIFICATION BY LICENSOR FOR INFRINGEMENT CLAIMS. Licensor hereby
         represents and warrants that the Software and Documentation are owned

         shall indemnify, hold harmless, and defend Licensee against any patent,
         copyright, or trade secret infringement claim, action or suit,
         including, without limitation, all costs, attorneys fees, and other
         fees arising therefrom, against Licensee arising from authorized use or
         licensing of the Software or Documentation in accordance with this
         Agreement provided that Licensee shall (i) give Licensor written notice
         of any allegation of infringement as soon as practicable after it is
         received and (ii) permit Licensor, at its option, to control the

         cooperate with each other regarding the defense against such action or
         suit. In the event a court of competent jurisdiction makes a
         determination that any Software or Documentation infringes, Licensor,
         at its option and expense, shall: (a) modify the infringing portion of
         the Software or Documentation so as to make it noninfringing, so long

         any Software or Documentation infringes.

         established by this Agreement is of licensor and licensee, each to

         or custom shall be deemed to amend this Agreement. Performance of any

         agreement, nor will it enter into any other agreement, that would
         render it incapable of satisfactorily performing its obligations
         hereunder or that would place it in a position of conflict of interest
         or be inconsistent with its obligations hereunder

         and regulations of governmental bodies or agencies in its performance

         EXPRESSLY UNDERSTOOD AND AGREED THAT IN THE EVENT ANY REMEDY HEREUNDER
         IS DETERMINED TO HAVE FAILED OF ITS ESSENTIAL PURPOSE, ALL OTHER

         without the written consent of the other party. Neither party may
         delegate its duties hereunder without the prior written consent of the
         other party, which shall not be

                                       11
<PAGE>

         unreasonably withheld. Any attempt by either party to assign any of its

         consent of the other party shall be null and void.

10.8     GOVERNING LAW. This Agreement shall be construed and enforced in

10.10    NO WAIVER. Neither party shall, by mere lapse of time, without giving
         notice or taking other action hereunder, be deemed to have waived any
         breach by the other party of any of the provisions of this Agreement.
         Further, the waiver by either party of a particular breach of this
         Agreement by the other shall neither be construed as nor constitute a
         continuing waiver of such breach or of other breaches of the same or
         any other provision of this Agreement.

10.11    OTHER SOFTWARE AND SERVICES. Licensor offers other software and
         services at separate charges under applicable written standard
         agreements of Licensor. Licensee and Licensor agree that any such
