          (a)  Expect as specifically provided herein or otherwise
               permitted by the other party in writing,
               Licensee may disclose Proprietary Material of
               Licensor, and Licensor may disclose

               employees and agents required to have
               knowledge of same to perform their duties pursuant
               to this Agreement.  All Proprietary
               Material shall be protected with the same degree of
               care as each party protects its own
               Proprietary Material, and in no case less than a
               reasonable degree of care.

          (b)  Except as may be permitted under any subsequent
               agreement entered into by the parties
               or by this Agreement, upon the termination of this

               destroy all Proprietary Material in the
               other's possession or control.

          (c)  Licensee shall only sub-license (or otherwise

               Programs pursuant to a Standard License Agreement
               with Licensee.  Licensor shall have
               reasonable access to such agreements in accordance
               with Section 8 of this Agreement.  If
               a breach of any such Standard License Agreement
               occurs, Licensee shall use its best
               efforts to take corrective action to remedy the
               breach and shall, in addition, notify
               Licensor of the breach and the corrective action
               taken.  Licensee shall take all reasonable
               steps to protect Licensor's proprietary rights to,
               and the confidentiality of, the Licensed
               Programs.

          10.3 Exceptions -- The foregoing obligations of
confidentiality shall not apply with respect to either party's
Proprietary Material to the extent that such material:

          (a)  Is within or later falls within the public domain

               Proprietary Material; or

          (b)  Is, or becomes, available to the receiving party
               from third parties who in making such
               disclosure have breached no written confidentiality
               agreement; or

          (c)  Is previously known by either party; or

          (d)  Is independently developed by either party.

          10.4 Licensee Development of Competitive Products --
Licensee is a software developer with a large number of Licensee
Software products that it markets to the computer industry.  This
agreement does not preclude Licensee from developing additional
proprietary software, or entering into arrangements with third-
parties for third-party software, that may become competitive with
the Licensed Programs.  Licensor acknowledges and agrees that
development of competing software is not in violation of this
Agreement provided that the confidential and proprietary
provisions of this Agreement are not violated and no Proprietary
Materials or confidential materials disclosed to Licensee may be
used by Licensee in the development of computer software that may
be competitive with Licensed Programs.  The foregoing is subject

          11.3 Entire Warranty -- THE EXPRESS WARRANTIES CONTAINED
IN THIS SECTION ARE THE ONLY WARRANTIES GIVEN BY LICENSOR WITH
RESPECT TO THE SUBJECT MATTER OF THIS AGREEMENT.  NO OTHER
WARRANTIES, EXPRESSED OR IMPLIED, ARE MADE BY LICENSOR, INCLUDING

damages, or for any claim against Licensee by any other person,

indemnify and hold Licensee harmless against any cost, damages, or
attorney's fees incurred by Licensee as a result of such claim,
provided that Licensee notifies Licensor of such claim.  Licensor
may, at its option and expense, procure for Licensee the right to
continue using the Licensed Programs, or replace or modify same to
make them non-infringing in a manner which does not impair the
usefulness of the Licensed Programs to Licensee for its intended
purpose.  Licensor shall have no liability to Licensee under any
provision of this Agreement with respect to any claim of
infringement which is based upon Licensee's unauthorized use or
combination of the Licensed Programs with software which is not
designated as a technical prerequisite (e.g. operating system
software) for the Licensed Programs, or which is not supplied, or
otherwise approved for such use, by Licensor.

     12.  TERM OF AGREEMENT

written notice of termination, effective upon the date of its

care, neither Licensor or Licensee can terminate the License
Agreement.

          13.4 Bankruptcy -- If a receiver is appointed over the

reorganization proceeding or if either party makes an assignment

its sending.

termination is properly effected by Licensee pursuant to Sections

event that this Agreement is terminated pursuant to Sections 13.1
or 13.2, or terminated by Licensor pursuant to Sections 13.3 or
13.4, Licensee shall return to Licensor all Licensor Proprietary
Material and Documents.  If Licensor terminates this Agreement
pursuant to Sections 13.2, 13.3 and/or 13.4, or if this Agreement
terminates pursuant to Section 13.1, the Licensee shall have the
right, at Licensor's option, to (a) purchase maintenance as
defined in Section 6 at reasonable and competitive prices, or (b)

                    15.79% of the Microstation upgrade list price,
                    unless and until the parties mutually agree to

               Microstation Review Upgrades-all Platforms
                    Version 5 $20 Per Copy ($100)
   

     c)   For software developers that are developing application
programs that run on top of the Licensed Programs, Licensee shall
have the right to grant a royalty free right to use the CLIPPER
and Windows NT versions of the Licensed Programs and Customer
Support Libraries.  NT product shall be for usage with OEM vendors
and strategic porting vendors interfacing with Licensee's
applications.  For participants in Licensor's ISD Program,
Licensee will not provide development copies of the Licensed
Programs.  All loans to application vendors will be subject to
Licensee's Marketing Loan Agreement, and all loans under this
program will be specifically for development purposes.  Licensee
agrees to provide, quarterly and upon request, Licensor a list of
companies it has provided development copies of the Licensed
Programs.  Licensee shall use its best discretion in the
allocation of these royalty-free development units.

     d)   Licensee agrees to sell DOS and MAC O/S versions of the
packaged Licensed Programs to Licensor at its current cost of
packaging.  The copies provided under this provision are to used
for Licensor's ISD program, for Licensor's Comprehensive Support
Program, loans to be technology journal editors and loans to
industry analysts.  The cost only versions (DOS and MAC) are not
to be sold by Licensor.

     e)   An upgrade program will be offered to Cadvance,
MacBravo, Personal Designer, Personal Machinist, Claris and
VersaCAD users.  The upgrade program will allow existing users of
the aforementioned competitive products to upgrade to Microstation
5.0.  The per copy royalty fee for this upgrade shall be $259
($1,500 list).  For sales through the dealer channel, upgrades for
more than twenty five units must be reviewed and approved by
Licensor, and for the direct channel, upgrades for more than 50
units must be reviewed by Licensor.  Where a competitive site
license is involved, the End User sit license invoice(s) will be
divided by $1,500 to determine the eligible number of upgrade
licenses.  Site license upgrades will also be  subject to the 25
and 50 units approval levels referenced above.  The upgrades are
to represented as for the End User's own use and not for resale.
This program is valid through June 30, 1994.  For the competitive
products being upgraded, End User must provide proof of purchase.

     f)   Licensee and Licensor from time to time will address
certain markets with  the idea of market penetration and this
philosophy will be known as the "Seed Program".  The intent of the
Seed Program is to penetrate the markets with a lower cost
product.  Seed Program copies are normally based on a previous
version of the Licensed Programs and for this reason, the End User
will not be allowed to upgrade Seed Program copies.  Licensee
agrees to undertake reasonable efforts to advise End Users that
the Seed Program copies are not upgradeable and to implement
systems to enforce this issue.  The original Microstation version
3 Seed Program is hereby terminated and Licensee will be allowed
to distribute existing Microstation version 3 Seed Program kits.
The new Seed Program will utilize Microstation version 4 and will
initially be targeted at Eastern Europe and the former Soviet
Union.  The local language versions of Seed Program products must
be sent to Licensor so that the resource files can be integrated
with the executable.  The integration will effectively lock the
resource file with the executable so that Seed Program products
cannot be converted to English.

     g)   For the U.S. Navy NAVFAC procurement, Licensee wants to
actively pursue the current installed AutoCAD customer base,
Licensee's intent is to encourage AutoCAD End Users to migrate to
the Microstation environment.  For the U.S. Navy NAVFAC End Users,
Licensor grants Licensee the royalty-free right to provide
Microstation upgrades to existing AutoCAD End Users.  The Navy
program shall be targeted at software upgrades and this free
upgrade offer is not to be part of a hardware sale, or the sale of
additional software.  This program will be valid through April 30,
1994, and after the initial term, Licensee and Licensor shall
discuss termination or extension of this program.  Where possible,
Licensee will obtain a copy of the AutoCAD main disk from the End
User.  Licensee will provide Licensor with a listing of the
upgrades provided and this will be provided with the quarterly
royalty report.

  
     h)   For the U.S. Navy NAVFAC procurement, the Microstation
royalty rate shall be $500 per copy and this fee shall be valid
for the term of the NAVFAC procurement.  Microstation upgrades
required under the NAVFAC procurements shall be made available at
the percentage rate outlined for upgrades in Section 1 of
Amendment #12.  Subject to End User review and approval, Licensee
intends to add the Licensed Programs (Microstation NT) as a
separate line item on the NAVFAC contract, and at this time, the
bid price will be 50% or less of list price.
   

     i)   Licensor shall have the right to sell the non-Clipper
versions of MicroCSL and shall retain all revenue generated by
these sales.

     j)   As previously outlined in a letter agreement dated April
22, 1993, Licensee may be required to deliver multiple versions of
the Licensed Programs to a single End User.  The requirement for
multiple version delivery is caused by the availability schedule
of Microstation version 5.  In this scenario, Licensee would
deliver version 4 of Microstation to a End User that purchased the
version 5 product and as version 5 becomes available, Licensee
will deliver the version 5 upgrade.  This upgrade situation is
currently only valid for the Microstation version 5 (DOS) release
and this situation should be cleared by December 15, 1993.  For
all deliveries of this type, Licensee shall pay Licensor the
version 4 royalty and this is based on the fact that Licensee must
deliver multiple kits.

     k)   Licensee plans to deliver the Licensed Programs based on
two (2) packaging schemes.  The first package scheme will include
the license, product serial number, media and documentation.  The
second package scheme will include only a license and serial
number, and this packaging scheme will be termed "Right to Run"
(RTR).  The second package scheme is targeted at large volume End
Users.  RTR list prices will be approximately $35 less than the
full packaged product.

2.   The following shall be added as a new Section 4.8.

4.8  "Try and Buy"-The purpose of this program is to
encourage large customers to make additional use of the Licensed
Programs.  The following points form an outline of the program.

          a)   This is a marketing program and is not intended to
alter licensing terms.

          b)   An End User must own a minimum of one hundred (100)
copies of Microstation version 5 to participate.

          c)   Each End User must sign a one year contract
agreeing to terms of the program.

          d)   During the term of the contract, Licensee will loan
the End User one copy of Microstation for each Microstation
license purchased.

          e)   As part of the contract, the End User must agree to
keep detailed usage records for all loaned products, and at a
minimum, the records must include peak daily concurrent usage.

and

          f)   At the end of the  contract term, the End User must
either purchase the loaned products or return them.  The End User
would be expected to purchase licenses to support its peak usage
level.

Licensee and Licensor agree to review this program on or before
October 15, 1994 and at that time, decide whether to extend or
terminate this program.

3.   The following shall be added as a new Section 4.9.

4.9  Major Account Migration Program(MAMP)-Licensee and
Licensor agree that a program must be put in place to address the
AutoCAD installed base.  The purpose of this program will be to
convince existing AutoCAD End Users to switch to Microstation.
This program shall have the following as its basis.

          a)   The End User must be an existing AutoCAD user to
participate.

          b)   The program will require a one year contract and
each contract will cover a single site, and also be for a single
term.

          c)   For each copy of Microstation purchased, Licensee
will loan the End User up to five additional copies of
Microstation.  The total number of loaned and purchased copies of
Microstation cannot exceed the total number of installed AutoCAD
copies.

          d)   The End User must have a minimum of one hundred
(100) copies of AutoCAD to participate.

          e)   the End User must agree to provide Licensee with
detailed Microstation usage reports and these reports must show
peak concurrent usage for each day of the most recent quarterly
period.

          f)   It is intended that the loan copies would be used
only where copies of AutoCAD would normally be used.

          g)   This program shall be valid through October 15,
1994, and on or before this date, Licensee and Licensor agree to
review the success of the MAMP.  If the MAMP is terminated,
Licensee shall have the right to continue to service existing MAMP
participants under the terms outlined herein, and this shall be
valid through the end of the participants' one year terms.

and

          h)   At the end of the contract term, the End User will
be required to either purchase the loaned copies or return them.
All purchases must be made during the agreement term.

4.   The following shall be added as a new Section 4.10.

4.10 Licensee may from time to time work with competitive
developers to upgrade an existing customer base and this program
shall be called the Cooperative Migration Program(CMP).  Under the
CMP, Licensee will offer to upgrade an existing competitive
customer base to the current version of the Licensed Programs.
The upgrades will carry a list price of $1,500 and a royalty rate
of $259.  The current participants in this program are IEZ and
DOGS.  Additional CMP participants may be added by mutual
agreement between Licensee and Licensor.

5.   The PlotLib license extended to Licensee based on Amendment
#12 dated July 30, 1993 shall be extended to cover I/EMS version
3.x (UNIX).  Other limitations still apply.

6.   Licensee has begun marketing Microstation version 5 product.
Licensor and Licensee agree that Microstation version 4 product
should be made available to End Users for at least nine (9) months
from the release date of version 5.

7.   A new product, Microstation Express, was outlined in
Amendment #12 date July 30, 1993.  Due to market conditions,
Licensee and Licensor have agreed to suspend marketing activities
until final product content is defined.  All reference to
Microstation Express is hereby deleted.

All other terms and conditions of the April 17, 1987 Software
License Agreement and as amended May 11, 1988, July 28, 1988,
August 30, 1988; August 4, 1989; May 23, 1990; November 20, 1991;
