            WHEREAS, EPIC is the developer and distributor of the computer

termed the "Licensed Program"); and

            WHEREAS, the Customer desires to license the Licensed Program;

            NOW, THEREFORE, in consideration of the mutual covenants and
agreements contained herein, the parties agree as follows:

            1. License. In consideration of the payment of the license fees set
forth herein, EPIC grants Customer a non-exclusive, non-transferable license,
without right of sublicense, to use the package of computer software identified
in Exhibit A in machine-readable form only, along with related user
documentation. The computer software and user documentation together constitute

            2. Scope of Rights. Customer may:

                        (a) Install the Licensed Program in Customer's own
facility at the locations specified in Exhibit A only;

                        (b) Use the Licensed Program in the configurations

            Except as specifically provided herein, EPIC reserves all rights in
and to the Licensed Program. Customer may not use or copy the Licensed program,
or any copy, adaptation, transcription, or merged portion thereof, except as
expressly authorized by this Agreement. Customer may not modify, disassemble or
decompile the Licensed Program without the prior written consent of EPIC;
provided, however, that if Customer's address set forth above is located within
a Member State of the European Community, then such activities shall be
permitted solely to the extent, if any, permitted by Article 6 of the Council
Directive of May 14, 1991 on the legal protection of computer programs, and

the license and this Agreement.

            3. Transfer of Rights. Customer's rights to use the Licensed Program
may not be transferred except to a successor in interest of Customer's entire
business who assumes the obligations of this Agreement in writing. Customer
agrees to notify EPIC of any such transfer within thirty (30) days of its

Agreement dated January 1, 1995.

            5. Taxes. Customer is solely responsible for payment of any taxes

liability arising from Customer's failure to report or pay such taxes.

            6. Support.

                        6.1 Support Agreement. The term and conditions of EPIC's

assistance with respect to such basic background information or any other

                                      -9-
   10
matters not directly related to the operation of the Licensed Program provide
that such fees are communicated in writing in advance and agreed to by Customer.

                        6.3 Hardware and Software. The Licensed Program is
designed for use with the hardware and accessories specified in Exhibit A.
Except as agreed otherwise in writing, EPIC assumes no responsibility under this

providing a proper environment and proper utilities for the computer system on
which the Licensed Program operates, including an uninterrupted power supply.

                        6.4 Conversion of Data Files. Customer is responsible
for converting its own data files for use with the Licensed Program.

            7. Title and Ownership. EPIC and its licensors shall own all right,
title and interest in and to the Licensed Program and all modifications and
enhancements thereof subject only to the rights and privileges expressly granted
hereunder. This Agreement does not provide Customer with title or ownership of
the Licensed Program but only a right of limited use.

            8. Confidentiality.

                        8.1 Confidentiality. The Licensed Program is a
commercially valuable, proprietary product of EPIC, the design and development
of which reflect the effort of skilled development experts and the investment of
considerable time and money. "Confidential Information" means (i) the Licensed
Program, in object and source code form, and any related technology, idea
algorithm or information contained therein, including without limitation design
techniques, and any trade secrets related to any of the foregoing; (ii) EPIC's
product plans, designs, costs, prices and names; non-published financial
information; marketing plans; business opportunities; personnel; research;
development or know-how; (iii) any information designated by the disclosing
party as confidential at the time of disclosure and reduced to writing and
designated as confidential in writing within thirty (30) days; and (iv) the
terms and conditions of this Agreement; provided, however, that "Confidential
Information" will not include information that: (a) is or becomes generally
known or available by publication, commercial use or to otherwise through no
fault of the receiving party; (b) is known and has been reduced to tangible form
by the receiving party at the time of disclosure and is not subject to
restriction; (c) is independently developed by the receiving party without use
of the disclosing party's Confidential Information; (d) is lawfully obtained
from a third party who has the right to make such disclosure; and (e) is
released for publication by the disclosing party.

                        Each party will protect the other's Confidential
Information from unauthorized dissemination and use with the same degree of care
that each such party uses to protect its own like information. Neither party
will use the other's Confidential Information for purposes other than those
necessary to directly further the purposes of this Agreement. Neither party will
disclose to third parties the other's Confidential information without the prior
written consent of the other party.

                        8.2 Restrictions Against Unauthorized Disclosure.
Customer may not or allow any third party, at any time, to (i) disclose or
disseminate the Licensed Program to any third party, or to any Customer employee
or consultant who does not need to obtain access thereto consistent with
Customer's rights under this Agreement; (ii) decompile, disassemble, reverse
engineer or attempt to reconstruct, identify or discover any source code,
underlying ideas, underlying user interface techniques, or algorithms of the
Licensed Program; (iii) provide, lease, lend, use for timesharing or service
bureau purposes, or otherwise use or allow others to use the Licensed Program
for the benefit of third parties; or (iv) modify, incorporate into or with other
software, or create a derivative work of any part of the Licensed Program.
Customer will devote its reasonable efforts to ensure that all of its employees,
consultants, independent contractors and all other persons afforded access to
the Licensed Program shall protect it against improper use, dissemination or
disclosure.

                        8.3 Remedies. If either party breaches any of its
obligations with respect to confidentiality and unauthorized use of the Licensed
Program hereunder, either party shall be entitled to equitable relief to protect
its interest therein, including but not limited to injunctive relief, as well as
money damages.

            9. Limited Warranty.

                        9.1 Product Warranty. EPIC warrants that the Licensed
Program shall be in substantial conformance with EPIC's published specifications
for the Licensed Program for a period of ninety (90) days following initial
delivery of the Licensed Program to Customer. EPIC does not warrant that the
Products will meet all of Customer's or Customer's customer's requirements nor
that the use of the Products will be uninterrupted or error free.

                        9.2 Defects not Covered by Warranty. EPIC's warranty

affect the Licensed Program; (ii) any alterations of or additions to the
Licensed Program performed by parties other than EPIC; (iv) use of the Licensed
Program in a manner for which it was not designed; (v) accident, negligence, or
misuse of the Licensed Program by any party other than EPIC personnel; or (vi)

Customer's exclusive remedy under the above warranties shall be to use its
reasonable efforts to correct reproducible errors that render the Licensed
Program nonconforming, provided that EPIC shall have no obligation to correct
all errors in the Licensed Program.

                        9.4 Disclaimer. EXCEPT FOR THE ABOVE EXPRESS LIMITED
WARRANTY, EPIC MAKES AND CUSTOMER RECEIVES NO WARRANTIES ON THE LICENSED
PROGRAM, EXPRESS, IMPLIED, STATUTORY, OR IN ANY OTHER

defend any suit or proceeding brought against Customer so far as based on a
claim that the Licensed Program, or any portion thereof, furnished by EPIC
constitutes an infringement of any patent, trademark, trade secret, copyright or
other third party property rights, if notified promptly in writing and given
authority, information and assistant (at EPIC's expense) for the defense of
same, and EPIC shall pay all damages and costs awarded therein against Customer.

constitute an infringement and the use of said Licensed Program or any portion
thereof, is enjoined, EPIC shall at its sole option and own expense, either

replace same with non-infringing program or modify it so it becomes
non-infringing, or remove said Licensed Program and refund the purchase price
and the transportation costs thereof.

            10. Limitation of Liability.

                        EXCEPT AS SET FORTH IN SECTION 9.5 ABOVE, IN NO EVENT
