PURPOSE.  IN NO EVENT SHALL ONESOFT (OR ITS EMPLOYEES, AGENTS OR SUPPLIERS) BE
LIABLE FOR ANY DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
(INCLUDING WITHOUT LIMITATION LOST PROFIT), EVEN IF ADVISED OF THE POSSIBILITY
THEREOF, AND REGARDLESS OF WHETHER ANY CLAIM IS BASED UPON ANY AGREEMENT,
NEGLIGENCE, WARRANTY, STRICT LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY.
ONESOFT'S TOTAL LIABILITY UNDER THIS AGREEMENT SHALL BE LIMITED TO THE LESSER OF
THE AGGREGATE FEES RECEIVED BY ONESOFT FROM CUSTOMER HEREUNDER, NOTWITHSTANDING
ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

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

     any form, are and shall remain the sole and exclusive property of ONESOFT
     and shall be deemed its Confidential Information.

2.   Except as expressly provided in this Agreement, CUSTOMER does not acquire
     any right or license in ONESOFT's Software, Tools, and/or Objects.

3.   "Tools" means ONESOFT's proprietary information and know-how and used at
     any time by ONESOFT in the conduct of its business. This includes, by way
     of illustration but not limitation, technical information, designs,
     templates, software modules, processes, methodologies, systems used to

     programs, plans, and/or any other similar information including

     information, to oppose such process before making disclosure.

7.   Each party understands and agrees that any use or dissemination of any
     information or materials in violation of this Agreement will cause the
     other party irreparable harm, will leave such party with no adequate remedy
     at law, and thus will entitle such party to injunctive relief in addition
     to all other remedies available under law. A party that violates its
     obligations concerning Confidential Information, shall reimburse the other
     party for reasonable costs and expenses (including reasonable attorneys'
     fees) incurred in enforcing its rights with respect to such violation.

     decompile, reverse engineer, recreate, disassemble, or otherwise attempt to
     determine the makeup of the Software. Except as expressly set forth herein,
     this Paragraph H does not constitute a license to use Software, Software
     Products, Tools, or Objects, which CUSTOMER must separately license from
     ONESOFT as necessary.

9.   Nothing in this Agreement shall be deemed to limit CUSTOMER's rights to
     develop and market functionally comparable products to the ONESOFT Product,
     or to provide e-commerce solutions, provided CUSTOMER does not violate the
     terms and conditions of Sections F and H herein.

10.  Unless otherwise agreed in writing, nothing herein shall be deemed to

     service mark of ONESOFT. The CUSTOMER shall not remove or alter any pending
     and/or existing copyright and/or trade secret notice affixed to any
     software or documentation provided by or through ONESOFT, without the

I.   GENERAL PROVISIONS
     ------------------

1.   Rights under this Agreement shall not be assigned, sublicensed, encumbered
     by security interest or otherwise transferred or resold by CUSTOMER
     (whether by operation of law or otherwise) without the prior written
     consent of ONESOFT, and any purported assignment, sublicense, encumbrance
     or other transfer of such rights, in violation of this Agreement, shall be
     void. An , acquisition, or merger of CUSTOMER by or with any person or
     entity who is not a party to this Agreement shall be treated as an
     assignment of this Agreement that is subject to the provisions of the
     foregoing sentence. ONESOFT may assign its rights and obligations under
     this Agreement to any party acquiring all or substantially all of its
     business, regardless of the form of the transaction.

2.   This Agreement may only be amended by instrument in writing signed by both
     parties. Schedules attached hereto are to be considered such a writing, and
     are hereby incorporated herein, once they are signed by both parties.

3.   The failure of either party to require the strict performance of any
     provisions of this Agreement in any one or more instances, or to exercise
     its rights hereunder or at law or equity, shall not constitute a waiver of
     any provisions or rights under this Agreement, and such provisions and
     rights shall continue in full force and effect.

4.   Neither party shall directly or indirectly solicit or offer employment to
     an employee or subcontractor of the other party during the term of this
     Agreement, and for *************** thereafter, unless otherwise agreed to
     by the respective party. For purposes of this Agreement, use of general
     advertising and independent employment agencies, if not directed at
     CUSTOMER's or ONESOFT employees, shall not constitute solicitation.

5.   If any provision of this Agreement is held to be invalid, the remaining
     provisions will continue to be valid and enforceable.

6.   ONESOFT shall be excused from performance hereunder to the extent that
     performance is prevented or delayed by causes beyond ONESOFT's reasonable
     control, including without limitation, Acts of God (fire, storm, floods,
     earthquakes, etc.), civil disturbances or disruption of telecommunications
     or other essential services.

7.   CUSTOMER shall not directly or indirectly export or re-export any services,
     software, equipment, technology or data supplied by ONESOFT under this
     Agreement to Afghanistan, the People's Republic of China or any Group Q, S,
     W, Y or Z country specified in Supplement 1 to Part 770 of the U.S. Export
     Administration Regulations. This provision and the assurances made herein
     shall survive termination of this Agreement whether in part or whole.

8.   Each party agrees to inform the other of any information made available to
     the other party that is classified or restricted data, agrees to comply
     with the security requirements imposed by any state or local government, or
     by the United States Government, and shall return all such material upon
     request. Each party warrants that its participation in this Agreement does
     not conflict with any contractual or other obligation of the party or
     create any conflict of interest prohibited by the U.S. Government or any
     other governmental authority, and shall promptly notify the other party if
     any such conflict arises during the term of this Agreement.

9.   Each party shall maintain commercially reasonable and adequate insurance
     protection covering its respective activities hereunder, including coverage
     for statutory worker's compensation, comprehensive general liability for
     bodily injury and tangible property damage, as well as adequate coverage
     for vehicles. Each party shall indemnify and hold the other harmless from
     liability for bodily injury, death and tangible property damage to the
     extent of the acts or omissions of such party, its officers, agents,
     employees or representatives acting within the scope of their work.

10.  The parties acknowledge that violation by a party of the provisions of
     Section H would cause irreparable harm to the other party that could not be
     adequately compensated for by monetary damages. In addition to other
     relief, it is agreed that temporary and permanent injunctive relief shall
     be available without necessity of posting bond to prevent any actual or
     threatened violation of such provisions or to enforce such provisions
     according to their terms.

                    ADDENDUM #1 TO ONESOFT COMMERCE PARTNER
                     JUMPSTART TRAINING PROGRAM AGREEMENT

     This Addendum to OneSoft Commerce Partner Jumpstart Training Program
Agreement is dated this 13/th/ day of September 1999 by and between OneSoft
Corporation ("OneSoft") and Compaq Computer Corporation ("Compaq"). This
Addendum shall amend the OneSoft Commerce Partner Jumpstart Training Program
entered between the parties dated August 25, 1999 ("Agreement") as follows:

     1.  Compaq, at its expense, shall ship to OneSoft a server on which OneSoft
         will install OneSoft's OneCommerce/TM/ 2.1 software ("Software"). Once
         the Software is installed, the server shall be returned to Compaq at
         OneSoft's expense.

     2.  Compaq shall be authorized to use the Software as specified in
         paragraph H.8 of the Agreement solely for evaluation purposes for ****
         days commencing on the date that Compaq is in receipt of the server on
         which the Software has been installed. Compaq is expressly prohibited
         from using the Software to develop websites for clients until the
         parties have entered into an agreement in which OneSoft extends Compaq
         a license to use the Software for additional purposes. Compaq's use of
         the Software for non-evaluation purposes shall constitute a material
         breach of the Jumpstart Training Program Agreement and its right to use
         the Software shall automatically be rescinded without further notice.

     3.  It is further stipulated and agreed that all other terms and conditions
         of said Agreement shall remain the same.
