including copyrights and any moral rights recognized by law; and (3) any other

which would result in material harm to Allaire, Allaire shall have the right to
immediately terminate this Agreement by written notice given at any time after

     Premier Support Engineer. Allaire will answer support requests within 2
     hours (or will notify Customer in the event the answer time is expected to
     exceed 2 hours), and will use its reasonable efforts to correct any
     reported problem within 5 days, but does not guarantee that it can correct
     all of Customer's reported problems. Allaire's support hereunder is limited
     to the Allaire Products and shall include the following:

     . Direct access to a senior-level Allaire Support Engineer with anticipated
       2 hour response time

     . Unlimited support for two authorized pre-named contacts

     . Up to two scheduled two-day on-site visits by an Assigned Premier Support
       Engineer.

     . Five (5) day resolution to all incidents. Resolution shall be defined as:
           (a) Providing a reasonable solution to the incident, or
           (b) Providing a reasonable work-around to the incident, or
           (c) Determination by Allaire that the incident is an enhancement
               request and forwarding the request to Allaire Product Management,
               or
           (d) Escalation by Allaire of the incident/bug to Allaire Engineering
               for review.

     Allaire looks to its customers to help it identify the priority category
     associated with a given call. While Allaire knows the Allaire Products and
     the environment, it does not always know the impact a given incident is
     having on Customer's development efforts. The Technical Support department
     uses priority levels to gain focus on the incidents that have the greatest
     impact on its customers. This helps Allaire to insure closure of critical
     incidents in a timely fashion, and helps all users of Allaire Products. All
     reported incidents will be addressed in some fashion, but the highest
     priority incidents will be expedited through the resolution process.
     Allaire priority schedule is included below:

                                       19
<PAGE>
      Priority Level                  Description
     ---------------------------------------------------------------------------
       1  Development or production halted, or having a severe impact on
          Customer's ability to continue development.
     ---------------------------------------------------------------------------
       2  Development or production impacted, but can continue for a reasonable
          amount of time before problem becomes critical. Customer should notify
          Allaire if this incident becomes a Priority 1.
     ---------------------------------------------------------------------------
       3  Customer is letting Allaire know about a problem, feedback is not
          currently required. If the customer decides that additional feedback
          is needed, it should notify Allaire of this change in status .
     ---------------------------------------------------------------------------

     Customers may call Allaire's Technical Support department at any time to
     check the status of an open incident. Allaire Technical Support will also
     update customers when an incident has been transferred to another area of
     the company. Customer requests to re-prioritize an incident must be made to
     a member of the Allaire Support Team.

     Allaire will use commercially reasonable efforts to perform the support
     services provided for under this Agreement ("Services"), but it retains the
     right to determine whether to revise, enhance or otherwise modify the
     Allaire Products and which requested features, functionality and other
     changes will be made to the Allaire Products, and it does not warrant or
     guaranty that all claimed or actual defects or errors will be corrected.
     Information provided by Customer in connection with Allaire's performance.
     of the Services may be used without restriction by Allaire to support or
     enhance the Allaire Products.

3.   Allaire Engineering will use reasonable efforts to correct incidents which
     have been determined to be product bugs in a timely manner. Reported bugs
     will generally be addressed in a scheduled maintenance release by severity
     on a first come, first served basis. Severe bugs which fall outside of the
     scheduled maintenance release will be evaluated for correction on a case by
     case basis.

4.   Customer may add additional products to this Support Agreement for the
     remainder of this term, in accordance with Allaire's then-current Upgrade
     Price list. Customer may purchase such Upgrade by issuing a purchase order
     under the same terms referenced in paragraph 7 and paying the applicable
     fee.

     specifications in paragraph 7 and paying the applicable fee:

     .  Scheduled 7x24 coverage for the Allaire Products listed on the Support
        Schedule.

        Premier Support Engineer for specific period of time outside of Allaire
        business hours, which

<PAGE>

        must be reserved by Customer at least 2 weeks in
        advance. Use of this add-on is restricted to two pre-named authorized
        contracts. Customer purchases this option by submitting a purchase order
        under the terms specified in paragraph 7 and by paying the applicable
        retainer and per incident fees. Allaire will respond to a request for
        coverage within two hours of the request.

     .  Extended hours for the Allaire Product(s) listed on the Support
        Schedule.
        ----------------------------------------------------------------

        Assigned Premiere Support Engineer for up to four consecutive hours
        during Allaire regular business days and up to eight consecutive hours
        during weekends and Allaire-recognized holidays, either of which must be
        reserved at least one week prior to scheduled coverage). Customer
        purchases this option by submitting a purchase order under the terms
        specified in paragraph 7 and by paying the applicable hourly charge.
        Allaire will respond to a request for coverage within two hours of the
        request.

7.   This Agreement shall not renew on an annual basis unless mutually agreed
     upon by both parties. In the event Customer desires to renew this
     Agreement, Customer shall issue a purchase order to Allaire thirty (30)
     days prior to the expiration of this Agreement and, provided Allaire
     notifies Customer that Allaire accepts Customer's purchase order, this
     agreement shall renew and Customer will be invoiced at Allaire's then
     current rates. Payment terms for renewals are net thirty (30) days from
     invoice date. Interest on late payments shall be charged at a rate of 1
     1/2% per month or the maximum allowable by law. Allaire reserves the right
     to cease providing services under this Agreement in the event of an overdue
     payment.

8.   Allaire warrants that the Services will be performed in the manner
     described in this Agreement by appropriately trained and qualified
     personnel using reasonable skill and diligence; provided, however, that
     Customer's sole remedy and Allaire's sole obligation in the event of a
     breach of the foregoing warranty shall be, at Allaire's option, for Allaire
     to either re-perform the non-conforming Services or to refund an
     appropriate portion of the fees paid by Customer for the non-conforming
     Services. EXCEPT FOR THE FOREGOING SENTENCE, ALLAIRE DOES NOT MAKE ANY
     GUARANTY, WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED (INCLUDING,
     WITHOUT LIMITATION, ANY WARRANTY AS TO QUALITY, PERFORMANCE,
     MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE), AND ALLAIRE
     EXPRESSLY DISCLAIMS ANY SUCH OTHER WARRANTY. Allaire's obligations under
     the foregoing warranty are subject to Allaire receiving written notice of
     the claimed non-conforming Services within ninety days of the date on which
     such Services were provided. THE FOREGOING IS CUSTOMER'S SOLE AND EXCLUSIVE
     REMEDY IN CONNECTION WITH THE SERVICES.

9.   ALLAIRE SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL,
     CONSEQUENTIAL, TORT OR COVER DAMAGES, INCLUDING, WITHOUT LIMITATION,
     DAMAGES RESULTING FROM LOSS OF PROFITS, DATA, BUSINESS OR GOODWILL, WHETHER
     OR NOT ADVISED OR AWARE OF THE POSSIBILITY OF SUCH DAMAGES. ALLAIRE'S
     AGGREGATE LIABILITY UNDER THIS AGREEMENT SHALL NOT EXCEED THE FEES PAID
     UNDER THIS AGREEMENT.

     not be modified in any way except in writing signed by both parties. Any
     variance from or addition to the terms of this Agreement contained in any
     purchase order or other notification will be of no effect. The invalidity
     or unenforceability of one or more provisions of this Agreement shall not

     this Agreement shall be construed in all respects as if such invalid or

other terms and conditions of this Agreement.

     5.4       The terms and conditions of this Agreement shall supercede any
conflicting terms and conditions appearing on any Purchase Order or invoice. All

----------------------------

     5.7       Nortel Networks shall keep true and accurate records of all
Contractual Products distributed, directly or through any channel, in accordance
with generally accepted accounting principles, consistently applied. No more
frequently than once per year, DeskTalk shall have the right (upon ten business
days prior notice) to have a certified public accountant selected by DeskTalk to
audit the records kept by Nortel Networks relating to the Contractual Product to
determine whether all license fees due have been paid. DeskTalk shall pay the
cost of such investigation, except in the event that such accountant finds that
royalties due for a period investigated have been underpaid by ten percent (1
0%) or more, in which case the entire cost of the investigation shall be borne
by Nortel Networks. Nortel Networks shall immediately pay to DeskTalk any
amounts discovered to be owed as a result of the investigation. If the annual
amount outstanding exceeds 15%, interest shall be paid at the rate of eighteen
percent (1 8%) per annum, calculated monthly from June 30 of the year the
underpayment occurred for each month the amount due was outstanding to the end
of the year the underpayment occurred.

(1 80) days following the date of Nortel Networks' receipt of DeskTalk's change
notification.

     8.5       Nortel Networks shall have the right to test all Contractual
Products free of charge.

     8.6       In no event shall payment for the Contractual Products by Nortel
Networks constitute a waiver of its right to have any non-conformity of the
Contractual Products to the specifications set forth in Annex 1 corrected in
accordance with the terms of DeskTalk's standard Warranty as described in the
DeskTalk Master Software License Agreement.

                       Support and Maintenance Services

DeskTalk shall provide all Support Services as set forth in this Annex 4 as
required per the DeskTalk Master Software License Agreement.

DeskTalk shall provide maintenance to Nortel Networks and its direct and
reseller end-users, consisting of post-sales telephone support and product bug
fixes and upgrades excluding changes in product functionality for a period of
fifteen (15) months from the date of receipt of Contractual Products by Nortel
Networks, except that the maintenance period shall be extended to eighteen (18)
months for the period September 1, 2000 through December 31, 2000. The fee for
such maintenance shall be in accordance with DeskTalk's current list price for
Silver maintenance.

Silver maintenance shall be listed as a separate line item charge on the invoice
from DeskTalk to Nortel Networks. Nortel Networks shall invoice its customers
for Silver maintenance at this same price, either as a separate line item or
bundled with its product sale. If the Nortel Networks direct or reseller end
user wishes to purchase a longer-period maintenance contract, the user shall be
forwarded directly to DeskTalk for said purchase. Annual maintenance renewals
shall be consummated by direct purchase order from the Nortel Networks direct or
reseller end user to DeskTalk.

Although DeskTalk provides 4 (four) distinct levels of product maintenance,
Nortel Networks will only be offering I (one), of which is the Silver
Maintenance Program as described below:

The Silver Maintenance Program, DeskTalk's standard maintenance contract,
provides unlimited Technical Support via the DeskTalk Support Center. The
DeskTalk Technical Support Center handles end user calls regarding perceived
product problems. The Technical Support Center provides, among others, the
following services:

 .    Receipt and logging of end user problem calls, including attempted problem
     classification as hardware, software or configuration issues.
 .    Attempted resolution of software problems by, if deemed appropriate:
     1.  Gathering and attempting to analyze debug information
     2.  Decoding of error messages and attempt to provide corrective action
         based on information provided
     3.  Verification of software release level and providing updates of
         DeskTalk products, if necessary
     4.  Liaison with DeskTalk Engineering, as needed for product defect
         resolution.

                              YEAR 2000 WARRANTY

1.   Definition of "Year 2000 Compliance"

"Year 2000 Compliance " shall mean that neither performance nor functionality is
affected by dates prior to, during and after the year 2000.

Warranty and Representation

DeskTalk warrants and represents that for so long as Nortel Networks or any end-
user has any right to use any of the Contractual Products that its Contractual
Product is "Year 2000 Compliant".

"Year 2000 Compliant" shall mean that neither performance nor functionality is
affected by dates prior to, during and after the year 2000 but before the year
203 1, and that the Contractual Products shall (i) process date and time related
data without causing any processing interruptions, abnormal terminations, or
changes in performance characteristics, and (ii) shall process and manipulate
all date and time related functions correctly.

In particular:

Rule 1. - No value for current date will cause any interruption in operation.
Rule 2. - Date-based functionality must behave consistently for dates prior to,
during and after year 2000 but before the year 203 1, including but not limited
to accepting date input, providing date output, and performing ongoing
operations on dates and portions of dates including, but not limited to,
calculating, comparing and sequencing of dates (in both forward and backward
operations spanning century boundaries).
Rule 3. - In all interfaces and data storage, the century in any date must be
specified either explicitly or by unambiguous algorithms or inferencing rules in
a disclosed, defined and predetermined manner.
Rule 4. - The Contractual Products shall correctly handle leap year calculations
(including but not limited to identification of leap years, interval
calculations, day-in-year calculations, day-of-the-week calculations, and week-
of-the-year calculations);
Rule 5. - The Contractual Products correctly store, retrieve and provide output
of all date and time data in a manner that is unambiguous as to century.

DeskTalk shall immediately notify Nortel Networks of any and all date-related
bugs, errors or deficiencies in the Contractual Products.  For the purpose of
problem resolution, any such date related bugs, errors or deficiencies shall be
deemed to be bugs, errors or deficiencies of the highest priority level, and
shall be resolved according to the procedures provided for such priority level
whether or not Nortel Networks is purchasing Support Services.

                OEM VENDOR CHANGE NOTIFICATION FORM and PROCESS

1.0.0     OEM Vendor Change Notification (OVCN) Process

          For the purposes of use of this document within the Nortel Networks NA
          ----------------------------------------------------------------------
          Inc. / DeskTalk Systems, Inc. Pass-thru Reseller Agreement, all
          ---------------------------------------------------------------
          references to "OEM Supplier" shall refer to DeskTalk Systems, Inc.
          -----------------------------------------------------------------

          1.1.0  Overview

          An OEM Vendor Change Notification Form (OVCN) is initiated by the OEM
          Supplier. It is the process by which changes to OEM products supplied
          to Nortel Networks are proposed, evaluated, approved or denied.

          The OEM Supplier shall submit all proposed changes and samples to the
          Nortel Networks OEM coordinator and Optivity Product Manager for
          review and testing.

          The completed OVCN form may be e-mailed to Nortel Networks at oem
                                                                        ---
          coordinator@nortelnetworks.com and to the Optivity Product Manager,
          ------------------------------
          Kelly Small, (email address: ksmall@nortelnetworks.com).

          Additionally, all supporting documentation must be shipped to the
          Nortel Networks OEM Coordinator at the shipping address detailed
          below, along with a copy of the original OVCN form submitted.
          Questions about the OVCN process may be directed to the OEM
          Coordinator. (Note: There is only one OEM Coordinator for both East
          and West Coast managed OEMS)

          Shipping Address: OEM Coordinator, Nortel Networks, 4401 Great America
          Parkway, MS SC1-02, Santa Clara, CA 95052-8185

          1.2.0  Processing the OVCN

          Once the OVCN is received, the OEM Coordinator will send a letter or
          e-mail acknowledging receipt of the OVCN to the OEM Supplier. This
          letter/e-mail will contain the OVCN number assigned by Nortel Networks
          and will reference the OEM Supplier's Internal Tracking number.

          The OEM Supplier must wait for an approval letter before processing
          -------------------------------------------------------------------
          any of the proposed changes in the OVCN.
          ---------------------------------------

          The OVCN will be distributed to the appropriate Nortel Networks
          Contacts for review. If the OVCN is rejected, the OEM Coordinator will
          send a letter or e-mail to the OEM Supplier notifying that the OVCN
          has been rejected.

                                      21
<PAGE>

     If the OVCN is approved, and a Nortel Networks Engineering Change Order
     (ECO) is not needed, the OEM Coordinator will send a letter or e-mail to
     the OEM Supplier approving the OVCN.

     If a Nortel Networks ECO is needed, the OEM ECO (Engineering Change Order)
     process will start.  The OEM Coordinator will send a letter or e-mail to
     notify the OEM Supplier that a Nortel Networks ECO is in process and will
     give the ECO number if available at that time.  After the ECO is approved,
     the OEM Coordinator will send another email/letter notifying the OEM
     Supplier of the ECO's approval.

     The date the change is effective is an agreed date between the OEM Supplier
     and Nortel Networks.

                                      22

2.0.0     A GUIDE TO FILLING OUT THE OVCN FORM

          Other than the OVCN Number, the rest of the fields in the OVCN Form
          will be filled out by the OEM Supplier, not by Nortel Networks. Some
          of the fields may not be applicable in all cases. The OVCN is a tool
          for the OEM Supplier to provide as much information as is needed by
          Nortel Networks to approve/reject the change and generate an ECO when
          needed.

          2.1.0  OVCN Number:

          Nortel Networks will assign the OVCN Number after the OEM Supplier
          submits the OVCN. The OEM Supplier will be notified immediately of the
          OVCN Number in an e-mail/letter acknowledging receipt of the OVCN.

          2.2.0  Issue Date:

          The date when the OEM Supplier generates the OVCN

          2.3.0  Reason For Change:

          The reason why the OEM Supplier wants to initiate the change e.g.
          failure, lowering of costs, unavailability of parts, software change

          2.4.0  Description of Change:

          A short description of what the change is

          2.5.0  Order Numbers/Products Affected:

          The OEM Supplier should list the Nortel Networks model numbers or
          software revisions of products affected, providing Nortel Networks
          order numbers where applicable

          2.6.0  Part Numbers Affected:

          The OEM Supplier should list their affected assembly and sub-assembly
          part numbers and what the new part numbers will be. The OEM Supplier
          should also list the corresponding Nortel Networks part numbers that
          are affected. (The OEM Supplier should leave the Nortel Networks P/N
          field blank if they do not know the Nortel Networks Part Number for an
          affected OEM Part Number)

          2.7.0  Attachments/Sample:

          When applicable the OEM Supplier should send attachments and samples
          via email/regular mail to the OEM Coordinator. Any attachment/sample
          sent through regular mail should be accompanied by a hard copy of the
          OVCN. A good example here is a change to the Bill of Material (BOM).

                                  23
<PAGE>

          2.8.0  Release Strategy:

          How does the OEM Supplier recommend releasing the Change, e.g. Cut-in,
          RMA etc.

          2.9.0  Special Instructions:

          Any special instructions by the OEM Supplier regarding the change.

                       MASTER SOFTWARE LICENSE AGREEMENT

                            LICENSE # ____________

           DESKTALK SYSTEMS, INC. MASTER SOFTWARE LICENSE AGREEMENT
                      (This is a license and not a sale)

DESKTALK SYSTEMS, INC. ("Licensor") is entering into this Master Software
License Agreement ("Agreement") with the following organization or individual
("Customer"):

-------------------------------------------------------------------------------

who wishes to license software products ("Software" as defined below) from
Licensor subject to the terms and conditions of this Agreement and the terms of
any Product Order ("Order" as defined below) that Customer submits to Licensor
and Licensor accepts.

1.   DEFINITIONS

A.   Software.  Means a software program product licensed by Licensor in machine
     readable form, unless otherwise specified, as well as any related
     materials, including documentation that accompanies the Software licensed.

B.   Anniversary Date.  Means the annual recurrence of the Delivery Date of the
     Software.

C.   Delivery Date.  Means the date Software is shipped from Licensor to
     Customer.

D.   Maintenance.  Means the provision by Licensor, in exchange for payment by
     Customer of any applicable Maintenance fees, of (i) reasonable telephone
     support, (ii) any corrections, enhancements, and/or modifications to the
     licensed Software which are not separately priced or marketed by Licensor,
     and (iii) updated and published user documentation made generally available
     to Licensor's customer base.

E.   Orders.  Means requests for Software submitted by Customer in a form
     acceptable to Licensor.  Any Orders shall expressly incorporate the terms
     and conditions of this Agreement by indicating the Agreement number
     assigned by Licensor, be signed by Customer and accepted by Licensor.

2.   GRANT/MAINTENANCE

A.   License.  Upon issuance of an Order from Customer and acceptance of the
     Order by Licensor, Licensor grants Customer a perpetual, non- transferable,
     non-exclusive license, without the right to sub-license, to use the
     Software for Customers internal business purposes only.  Customer may
     install and use the Software for each user and server purchased from
     Licensor as indicated on the Orders.  Licensor retains all title to

                                      26
<PAGE>

     the licensed copy, and all copies thereof. No title to the license copy, or
     any intellectual property therein, is transferred to the Customer. Customer
     shall not (i) provide Software access to any non-affiliated entity of
     Customer, including, but not limited to, third-party individuals being
     provided services by Customer for payment (unless such party agrees to the
     terms hereof); or (ii) decompile, disassemble or otherwise reverse engineer
     the Software. Customer, solely to enable it to use the Software, may make
     archival copies of the Software's computer program, provided that any such
     copy shall include Licensor's copyright and any other proprietary notices.
     Customer shall have no other right to copy or distribute, in whole or in
     part, the Software. Any copy of the Software made by Customer is the
     exclusive property of the Licensor.

B.   Inspection.  No more than twice in any twelve month period, and upon
     reasonable notice to Customer, Licensor may audit the Software in use by
     Customer.

C.   Maintenance.  If Maintenance is purchased with the initial Order.
     Maintenance for year two (2) will be due on the Anniversary Date of the
     License and thereafter, shall automatically renew annually on the
     Anniversary Date for an additional one (1) year term at the then current
     Maintenance fees.  Customer may terminate Maintenance obligations by
     providing written notification to Licensor at least sixty (60) days prior
     to the next Anniversary Date.  Licensor may terminate its Maintenance
     obligations if Customer is in breach of this license and has failed to cure
     said breach after notice and an opportunity to cure, or if Licensor
     terminates its Maintenance program to its customers generally, or the
     Customer modifies the Software, and it is determined that the modification
     has caused the malfunction.

3.   LICENSE OF SYBASE SQL SERVER

A.   Duty to License.  Customer agrees and understands that it must purchase
     appropriate Sybase SQL Server licenses in order to utilize TREND Server,
     Poller, Expert Client, Reporting Client and TRENDweb (ad hoc feature)
     modules.

B.   Sybase Licenses Purchased with TREND.  In the event that Customer chooses
     to purchase Sybase Licenses from Licensor, then, and only then, the
     following additional terms and conditions shall apply to this license
     agreement:

     (i) You may use each copy of the Sybase Object Code (and accompanying
documentation) which were ordered by you ("Programs") solely for your internal
business purposes.  Each copy may be used on one Machine running the operating
system for which the license was ordered.  A "Machine" is a hardware system with
any number of processors running a single copy of the operating system on which
the Programs are running.  If such license is designated as a Networked License,
each copy of the Program may be accessed by any and all Seats that are licensed
to access the Program subject to the following restrictions: (i) Workplace Seats
licensed to access a particular Program may only access the Workplace level of
such Program, and (ii) Enterprise Seats licensed to access a particular Program
may access the Workplace and Enterprise levels of such Program.  However, if
such license is designated

                                      27
<PAGE>

as a Concurrent License, each copy of the Program may be accessed at any one
time by no more than the number of Seats licensed for that particular copy of
the Program. Whether a Networked License or a Concurrent License, use of other
software or hardware which reduces the number of Seats directly accessing the
Programs (sometimes called "multiplexing" or "pooling") does not reduce the
number of Seats required to be licensed, but rather the number of licensed Seats
must be equal to the number of distinct inputs to the multiplexing software or
hardware. If the license is designated as a Standalone Seat License, the copy of
the Program may only be accessed by the Machine on which it resides. A "Seat" is
a specific identifiable unique accessor of information such as a terminal, PC,
single user workstation or real time device. An "Application Deployment Seat is
a seat which can access the relevant Program solely for the purpose of running
the applications which you licensed from Licensor and extracting data on a read
only basis from the Licensor's application for use with other applications. A
license for a copy of a Program will allow you to use the indicated version or
instead any earlier version for which you already have a Primary Copy. If you
have licensed a Run-Time Program, the Program may only be used to run your
applications but it cannot be used to (i) develop or modify applications, or
(ii) perform other programming tasks. If an ODBC Driver has been licensed for a
particular operating system, then you may make and use an unlimited number of
copies of such Program running on such operating system. This license does not
entitle you to direct Sybase Maintenance. TRENDweb products are licensed as a
Run-Time Program only. TRENDweb Clients may be distributed to third parties
provided services by licensee.

     (ii) The Programs may not be transferred, sold, assigned, or otherwise
conveyed (whether by operation of law or otherwise) to another party without
Sybase's prior written consent.  Provided that you are entitled to maintenance
and support and are current in your payment of support fees, you may transfer a
Program to a different operating system subject to Sybase transfer policies and
payment of all applicable fees, as specified in Sybase's then current price
list.  Transfer of a Program outside the country in which it was originally
delivered to you is not permitted without Sybase's prior written consent and is
subject to compliance with all applicable export restrictions.  You may not use
the Programs for timesharing, rental or service bureau purposes.  Results of
benchmark or other performance tests run on the Programs may not be disclosed to
any third party without Sybase's prior written consent.

4.   FEES

All license fees and Maintenance fees and, if applicable, Sybase License fees
are due and payable within thirty (30) days after the invoice date.  Customer
shall pay all applicable shipping charges, and sales, use, personal property, or
similar taxes, tariffs or governmental charges, exclusive of Licensor's net
income and corporate franchise taxes.  Service charges of the lesser of the
maximum amount permitted by law or one and one-half percent (1-1/2%) per month
will accrue on all accounts past due by more than thirty (30) days.

5.   OWNERSHIP

                                      28
<PAGE>

A.   Title.  Licensor owns all proprietary rights, including patent copyright,
     trade secret, trademark and other proprietary rights, in and to the
     Software and any corrections, bug fixes, enhancements, updates or other
     modifications, including custom modifications made by Licensor, to the
     Software.

B.   Transfers.  Under no circumstances shall Customer sell, license, publish,
     display, distribute or otherwise transfer to a third party the Software and
     any copy thereof, in whole or in part, without licensor's prior written
     consent.  Except Customer may assign this agreement to any wholly-owned
     subsidiary, or to any Successor of all or substantially all of its business
     or assets.

6.   CONFIDENTIAL INFORMATION

Licensor represents that the Software contains proprietary information,
including trade secrets, know-how and confidential information, and that is the
exclusive property of Licensor.  During the period this Agreement is in effect
and at all times after its termination, Customer and its employees and agents
shall maintain the confidentiality of this information and not sell, license,
publish, display, distribute, disclose or otherwise make available this
information to any third party or use such information except as authorized by
this Agreement.  Customer shall not disclose any such proprietary information
concerning the Software, including any flow charts, logic diagrams, user manuals
and screens, to persons not an employee of Customer without the prior written
consent of Licensor.

7.   LIMITED WARRANTY AND LIMITATION OF REMEDY

A.   For thirty days from the date of the initial shipment of the Software to
     Customer, Licensor warrants that the Software, when used in accordance with
     the Licensor's specifications therefor, will operate in all material
     respects in conformity with the published manuals for that Software, and
     the Software media shall be free from defects.  In the event of failure to
     meet the foregoing limited warranty, Customers sole remedy, at Licensor's
     option, shall be replacement of the defective Software or a refund of the
     license fees actually paid to Licensor for the affected Software.  This
     limited warranty gives Customers specific legal rights.  Customer may have
     other rights, which vary among states/provinces.  Some states/provinces do
     not allow limitation on the duration of implied warranties so the above
     limitation may not apply.

B.   THE WARRANTY IN THIS AGREEMENT REPLACES ALL OTHER WARRANTIES EXPRESS OR
     IMPLIED, INCLUDING ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
     PARTICULAR PURPOSE.  LICENSOR DISCLAIMS AND EXCLUDES ALL OTHER WARRANTIES.
     IN NO EVENT WILL LICENSOR'S LIABILITY OF ANY KIND INCLUDE ANY SPECIAL,
     INCIDENTAL OR CONSEQUENTIAL DAMAGES, INCLUDING LOST PROFITS, EVEN IF
     LICENSOR HAS KNOWLEDGE OF THE POTENTIAL LOSS OR DAMAGE.  NO WARRANTY IS
     MADE THAT ALL ERRORS IN THE SOFTWARE WILL BE CORRECTED, OR THAT THE
     SOFTWARE

                                      29
<PAGE>

     FUNCTIONALITY MEETS YOUR REQUIREMENTS.  CUSTOMER ACKNOWLEDGES ITS
     RESPONSIBILITY TO (I) REGULARLY BACK UP DATA MAINTAINED ON ANY COMPUTER
     SYSTEM USING THE PROGRAMS AND (11) ADEQUATELY TEST PRIOR TO DEPLOYMENT EACH
     PRODUCTION VERSION OF THE SOFTWARE IN A CONFIGURATION WHICH REASONABLY
     SIMULATES YOUR PLANNED PRODUCTION ENVIRONMENT.

C.   Licensor will not be liable for any loss or damage caused by delay in
     furnishing the Software or any other performance under this Agreement.

D.   License Key Managed.  Customer understands and acknowledges that the
     Software requires a key to operate.

8.   TERM AND TERMINATION

The terms of this Agreement shall continence on the date it is executed by
Licensor and shall continue in effect until terminated as provided herein.  Any
License for Software may be terminated by Licensor in the event that Customer is
in default of any material terms of this Agreement provided Licensor provides
notice of the violation and Customer fails to remedy the default within thirty
days of said notice.  Upon termination Customer shall return the Software to
Licensor.  The provisions of Sections 4, 5, 6, 9, 10, 11 and 12 shall survive
the termination of this Agreement.

9.   RESTRICTION ON EXPORT AND RE-EXPORT

Customer agrees to comply with all export and re-export restrictions and
regulations imposed by the government of the United States, Customer agrees not
to export the Software to any countries listed on Exhibit "All.  Exhibit "A" may
be amended from time to time by Licensor.  This section shall survive the
expiration or termination of this licensing agreement.

10.  U.S. GOVERNMENT RESTRICTED RIGHTS/CIVILIAN AGENCY RESTRICTED RIGHTS

If this license is acquired under a U.S. Government contract use, duplication,
or disclosure by the U.S. Government is subject to restrictions as set forth in
DFARS 252.227-7013(c)(ii) for Department of Defense contracts and as set forth
in FAR 52.22719(a)-(d) for civilian agency contracts.  Licensor reserves all
unpublished rights under the copyright laws of the United States.

11.  INDEMNIFICATION

Licensor warrants that it has the right to license any Software licensed
hereunder.  Licensor hereby agrees to indemnify and hold harmless Customer, its
directors, officers, employees and agents and defend any action brought against
same with respect to any claim, demand, cause of action, debt or liability,
including attorneys' fees, to the extent that it is based upon a claim that the
Software, as produced by Licensor, infringes or violates any patents,
copyrights, trade

                                      30
<PAGE>

secrets, licenses or other property rights of any third party: provided that (i)
Customer gives prompt written notice to Licensor of any suit, and (ii) Licensor
shall have sole control of the defense of any action or claim and all
negotiations for settlement or compromise thereof Customer may elect to
participate in any such action with an attorney of its own choice and at its own
expense. In the event Customer is precluded by a court of competent jurisdiction
from using the Software as a result of the infringement by Licensor of any
patent, trademark, trade secret, or copyright of a third party, Licensor may, in
its reasonable discretion (i) obtain the right to use the Software for the
Customer, or (ii) replace or modify the Software so that it no longer infringes,
or (iii) if neither of the above is commercially reasonable then Licensor may
terminate this Agreement for the affected Software with a pro-rata refund of the
License fees paid by the Customer for the affected Software based on a useful
life of three years. If Customer does not timely notify Licensor, as required
herein, Customer's rights under this section shall terminate.

12.  GENERAL PROVISIONS

     and exclusive statement of the agreement between the parties (other than

     parties relating to this agreement.

B.   Amendment.  This agreement may not be modified, altered or amended except
     by written instrument duly executed by the authorized representatives of
     each of the parties.

     any right provided for in this agreement shall not be deemed a waiver of
     any further right under this agreement.

     unenforceable under any applicable statute or rule of law, it is to that
     extent to be deemed omitted.  The remainder of the agreement shall be valid
