                                        mdbs
                           Micro Data Base Systems, Inc.
                        COOPERATIVE SALES SUPPORT AGREEMENT

This Agreement is between Fourth Shift Corporation (hereinafter referred to
as "Customer") and Micro Data Base Systems, Inc. (hereinafter referred to as
"mdbs").

WHEREAS:  Customer desires to enter into a Cooperative Sales Support
Agreement with mdbs; and

WHEREAS:  mdbs also desires to enter into a Cooperative Sales Support Agreement
with Customer; and

WHEREAS:  the parties intend to enter into an mdbs Business Partner Agreement.

NOW, THEREFORE, for due consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties agree as follows:

1.   ENTITLEMENTS AND OBLIGATIONS
     a)  mdbs and Customer will perform the cooperative sales support activities
         described in detail on Addendum I to this Agreement.
     b)  mdbs and Customer agree to bear their own expenses related to this
         Cooperative Sales Support Agreement unless otherwise specifically
         agreed.
     c)  For any breach of this or related Agreements, any discounts will end
         and current list prices shall apply.
     d)  In order to execute this Agreement, Customer must be a licensed end
         user of mdbs Development System software.
     e)  Customer agrees that the contents of this Agreement and its Addenda,
         and any extensions or modifications thereto, shall be held in strict
         confidence and not released to any third party without the prior
         written consent of mdbs, or as required by a court of competent
         jurisdiction.  This obligation shall survive termination of this
         Agreement.

2.   TERM
     a)  The term of this Agreement is July 1, 1997 through June 30, 1998.
     b)  If a Business Partner Agreement is in effect, any termination or
         expiration of this Agreement shall concurrently terminate the Business
         Partner Agreement, and Customer will no longer be entitled to the
         rights and privileges of Business Partner status.  mdbs shall have the
         right to terminate this Agreement in the event of a breach by Customer
         by giving Customer written notice of termination.  A breach by
         Customer under either the Business Partner Agreement or the Tailored
         Technical Services Agreement shall constitute a breach hereunder, and
         in such event mdbs shall have the right to terminate this Agreement
         upon written notice to Customer.  A breach or termination of any of
         Customer's End User or Runtime Distribution License Agreements shall
         also constitute a breach hereunder, and in such event mdbs shall have
         the right to terminate this Agreement upon written notice to Customer.
     c)  In the event that termination of this Agreement is the result of
         non-payment, violation of licensing agreements, or any other breach of
         applicable agreements, mdbs will be entitled to all available damages
         and remedies provided under all applicable agreements, and as
         otherwise provided by law, including reimbursement for reasonable
         attorney's fees and enforcement costs.

3.   MISCELLANEOUS
     a)  No employment, joint venture, partnership or agency relationship is
         created by this Agreement.  Customer has no right or authority to bind
         mdbs to any obligation or in any other manner.  This Agreement is
         governed by the laws of the State of Indiana, the United States and
         the Universal Copyright Convention.  Disputes, claims, and litigation
         under this Agreement shall be subject to the exclusive venue and
         jurisdiction of a court of competent authority in Tippecanoe County in
         Indiana.  This Agreement represents the entire agreement between the
         parties regarding the subject matter pertaining hereto; no verbal
         representations are binding; any amendment to this Agreement must be
         signed by both parties to be of any force or effect.
     b)  If any provision of this Agreement (or portion thereof) is determined
         to be invalid or unenforceable, the remaining provisions of this
         Agreement shall not be affected thereby and shall be enforceable as
         though said invalid or unenforceable provision (or portion thereof) is
         not contained in this Agreement.  The failure of either party to this
         Agreement to insist upon the strict performance of any of the
         provisions contained herein shall in no way constitute a waiver by
         either in the performance of or compliance with any of the terms and
         conditions set forth in this Agreement.
     c)  This Agreement may not be assigned without the prior written consent
         of mdbs, which such consent will not be unreasonably withheld.  mdbs
         reserves the right to assign this Agreement.
