      6.2   License. Customer will be entitled to use the Creations solely in
            connection with its authorized use of the Software, such right being
            embodied in, and subject to, Customer's license of the Software

            renew at the end of the initial term and any subsequent term for a

            Maintenance and Support at least ninety (90) days prior to the
            expiration of the then-current term. Termination of Maintenance and
            Support upon failure to renew will not affect Customer's license of
            the Software or the Creations.

            Baan will provide telephone assistance with respect to the

            Maintenance and Support at the Customer Site. In such event Customer

      7.5   Maintenance Fee. The Maintenance Fee for standard hours of service
            for each twelve (12) month period of Maintenance and Support will be
            19% of the total amount paid by Customer for the Customizations;
            provided that Customer has contracted for Maintenance and Support
            under the License Agreement. Such Maintenance Fee is in addition to
            the Maintenance Fee due under the License Agreement. Customer owes a
            percentage of the Maintenance Fee which corresponds to the number of
            months of the first term. The Maintenance Fee is due and payable in
            fill in advance within thirty (30) days after the date of Baan's
            invoice. Any amounts not paid within thirty (30) days will be
            subject to interest of one percent (1%) per month, which interest
            will be immediately due and payable. Each calendar year, the
            Maintenance Fee may be modified by Baan due to general price
            increases and/or general inflation increases which is reflected in
            the Consumer Price Index, but shall, for a period of four years from
            the Effective Date, in no event exceed five percent (5%) plus the
            increase in the Consumer Price Index for the applicable time period,

            Maintenance Fee, Customer may discontinue Maintenance and Support.
            If Customer elects not to renew Maintenance and Support, Customer
            may re-enroll only with Baan's consent and only upon payment of the

            of all Maintenance Fees that would have been paid had Customer not
            terminated Maintenance and Support.


                                      -3-


      7.6   Eligibility of Software/Responsibility of Customer. The provisions
            of Sections 6.6 and 6.7 of the License Agreement will be applicable
            to Maintenance and Support for Customizations, as if set forth in
            full in this Agreement.

      7.7   Assignment of Duties. Baan may assign its duties of Maintenance and
            Support to a third party, provided that Baan will remain responsible
            for the actions of such third party. Any such assignment is subject
            to Customers consent, which consent shall not be unreasonably
            withheld or delayed.

8 Limited Warranty and Limitation of Liability

      8.1   Baan warrants that for a period of ninety (90) days from Baan's
            completion of any Customizations, these Customizations will conform
            to the Functional Specifications. If the Customizations are
            demonstrated not to conform to such Functional Specifications, Baan
            will, at Baan's option, undertake to correct the Customizations so
            it conforms with such Functional Specifications, or, if the
            foregoing is not commercially practicable, terminate this Agreement
            and refund the fees paid for the Customizations pursuant to Section
            5.1. The foregoing are Customer's sole and exclusive remedies for
            breach of warranty. The warranty set forth above is made to and for
            the benefit of Customer only. The warranty will apply only if:

            (a)   the Customizations have been properly used at all times and in
                  accordance with the instructions for use; and

            (b)   no modification, alteration or addition has been made to the
                  Software and/or the Customizations, by persons other than Baan
                  or Baans authorized representative.

      8.2   Except as set forth above, Baan makes no warranties, whether
            express, implied, or statutory, regarding or relating to the
            Customizations, any Documentation, or any materials or services
            furnished or provided to Customer under this Agreement Baan
            specifically disclaims all implied warranties of merchantability and
            fitness for a particular purpose with respect to the Customizations,
            Documentation and said other materials and services, and with
            respect to the use of any of the foregoing. In addition, Baan
            disclaims any warranty with respect to, and will not be liable or
            otherwise responsible for, the operation of the Customizations if
            programs are made through the use of Baan Tools or non-Baan software
            that change, or are able to change, the data model of the
            Customizations.

      8.3   In no event will Baan be liable for any loss of profits, loss of
            use, business interruption, loss of data, cost of cover, or
            indirect, special, incidental, or consequential damages of any kind
            in connection with or arising out of the furnishing, performance or
            use of the Customizations, or the services, whether alleged as a
            breach of contract or tortious conduct, including negligence, even
            if Baan has been advised of the possibility of such damages. In
            addition, Baan will not be liable for any damages caused by delay in
            delivery or furnishing the Customizations or the services. Baan's
            liability under this Agreement for direct, indirect, special
            incidental and/or consequential damages of any kind, including,
            without limitation, restitution, will not, in any event, exceed the
            fees paid by Customer to Baan under Section 5.1 of this Agreement.

      8.4   Customer shall indemnify Baan against all claims by third parties
            related to (the performance of) this Agreement.

      8.5   The provisions of this Section 8 allocate risks under this Agreement
            between Customer and Baan. Baan's pricing reflects this allocation
            of risk and limitation of liabilities.

      8.6   No action arising out of any breach or claimed breach of this
            Agreement or the transactions contemplated by this Agreement may be
            brought by either party more than one (1) year after the cause of
            action has accrued. For purposes of this Agreement, a cause of
            action will be deemed to have accrued when a party knew or
            reasonably should have known of the breach or claimed breach.

      8.7   No employee, agent, representative, or affiliate of Baan has
            authority to bind Baan to any oral representations or warranty
            concerning the Software or the Services. Any written representation
            or warranty not expressly contained in this Agreement will not be
            enforceable.

            Sections 8, 9 and 13.14 of the License Agreement, all of which will
            survive termination of this Agreement, regardless of the reason for
            termination.
