                       CONFIDENTIAL SETTLEMENT AGREEMENT

        THIS CONFIDENTIAL SETTLEMENT AGREEMENT ("Agreement") is entered into
this 13th day of September, 1995 by and between THOMSON TRAINING AND SIMULATION
LIMITED ("TTSL"), Gatwick Road, Crawley, West Sussex RH10 2RL, United Kingdom
and THOMSON-CSF. S.A. ("TCSF"), 173, Boulevard Haussmann - 75415 Paris Cedex 08,

Arlington Downs Road, Arlington, Texas 76011 (collectively, "HUGHES") and EVANS
& SUTHERLAND COMPUTER CORPORATION ("E&S"), 600 Korans Drive, Salt Lake City,
Utah 84108.

        WHEREAS. on or about October 11, 1986, E&S entered into a working
agreement (the "Working Agreement") with Rediffusion Simulation Limited
("Rediffusion"), a corporation existing under the laws of the United Kingdom;
and

        WHEREAS, Rediffusion was subsequently acquired by HAC, which changed
Rediffusion's name to Hughes Rediffusion Simulation Limited; and

        WHEREAS, as of January 15, 1991, E&S and Rediffusion amended the Working
Agreement; and

        WHEREAS, Rediffusion was acquired from HAC by a subsidiary of TCSF on or
about December 31, 1993, and TCSF subsequently changed Rediffusion's name to
TTSL; and

 
        WHEREAS, certain disputes have arisen between E&S, Thomson and HAC with
regard to said Working Agreement, and other matters.

    NOW, THEREFORE, for good and valuable consideration, the receipt and legal
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

       1.   Hughes Payment to E&S. On the effective date of this Agreement, 
            ---------------------
HAC shall pay to E&S the sum of Three Million Seven Hundred Fifty Thousand
($3,750,000) by wire transfer to the account and financial institution
designated by E&S.

        2.   Agreement between E&S and HTI. On the effective date of this
             -----------------------------
Agreement, E&S and HTI shall enter into a separate agreement pursuant to which
E&S and HTI will agree (a) to team on certain projects for U.S. and foreign
(other than the U.K. MOD or other U.K. platform) military sales, (b) to continue
with discussions regarding the implementation of a technology exchange program
in connection with such projects, (c) to otherwise work together and (d) to
continue to be bound by the confidentiality restrictions in paragraph 4.1 of the
Working Agreement, notwithstanding termination of such Working Agreement, such
separate agreement to be subject to such other terms and conditions as may be
separately negotiated by E&S and HTI. Such separate agreement shall be an
independent obligation of E&S and of HTI and shall not, after its execution and
delivery on the effective date of this Agreement, be considered part of this
Agreement. In no event shall Thomson have any liability or obligation to either
E&S or Hughes in the event of any breach by either E&S or HTI of any obligation
under such separate agreement between E&S and HTI.

        3.    Agreement between E&S and TTSL. On the effective date of
              ------------------------------
this Agreement, E&S and TTSL shall enter into a separate agreement pursuant to
which E&S and TTSL will

                                       2

 
agree (a) that the Working Agreement, as amended and supplemented, and the
Rediffusion Simulation Limited OEM Volume Purchase Agreement (Oct. 1, 1986),
Rediffusion Simulation Limited Basic Ordering Agreement (Oct. 1, 1986), Evans &
Sutherland Computer Corporation OEM Volume Purchase Agreement (Oct. 1, 1986),
and Evans & Sutherland Computer Corporation Basic Ordering Agreement (Oct. 1,
1986) has each been effectively terminated and is no longer effective, except
for the provisions of paragraph 4.1 of the Working Agreement which shall
continue to be binding upon E&S and TTSL, (b) to work in good faith to
resolve all support claims and other issues raised by customers of TTSL or of
E&S ("Current Customers") that purchased E&S "cgi equipment" (as defined in the
Working Agreement) or to whom E&S sold TTSL display systems under the terms of
the Working Agreement, (c) to meet to jointly explore in good faith the
possibility of establishing a new business relationship in an effort to reach
agreement to provide needed products and services to civil customers on a
mutually acceptable pricing basis and (d) to meet and negotiate in good faith a
new working arrangement with regard to addressing a method for E&S and TTSL to
jointly market their products and services to the "civil market" as defined in
the Working Agreement, as well as other markets, and (e) to jointly prepare and
issue a press release regarding the relationship between E&S and TTSL, such
separate agreement to be subject to such other terms and conditions as may be
separately negotiated by E&S and TTSL. Such separate agreement shall be an
independent obligation of E&S and of TTSL and shall not, after its execution and
delivery on the effective date of this Agreement, be considered part of this
Agreement. In no event shall Hughes have any

                                       3

 
liability or obligation to either E&S or TTSL in the event of any breach by 
either such party of any obligation under such separate agreement between E&S
and TTSL.

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

     and (2) for which the developing party has at least two purchase agreements
     and (3) for which the developing party has produced a demonstrable
     prototype unit.

 B)  The term "visual system program" shall mean applications where (1) the
     simulator is a vehicle (air, land, or water) or weapon system simulator and
     (2) the simulator is used for the purpose of training and (3) the images
     computed by the system depict terrain, natural and cultural featured,

     required to operate and maintain the products. Such items shall include
     maintenance services, field engineering, documentation, manual, training
     and spare parts.

 D)  The term "support" shall mean those items required to provide a deliverable
     product or service that best meets the intended use. Such support would

3.0  TEAMED PROGRAMS
     ---------------

     Except as provided hereunder, HTI will consider only E&S visual systems for
     the listed Team Programs and market accordingly to the end customer. Except
     as provided hereunder, E&S will not respond to requests from other
     systems/simulator suppliers and will market accordingly. In the event the
     end customer indicates its desire for a different visual system or a
     different simulator system supplier before release of initial bid package,
     then HTI and E&S will meet to discuss an alternate pursuit strategy and, by
     mutual agreement, dissolve the teaming arrangement on that specific
     program. The agreement to separate must be in writing, signed by authorized
     agents of each company and be on a program by program basis.

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

4.1  BEST EFFORT PROGRAMS
     --------------------

     With regard to the following programs, HTI will make every effort to use
     E&S visual system products and services wherever E&S has a competitive and
     suitable product which is acceptable to the end customer. Similarly, E&S
     will make every effort to team with HTI wherever HTI has a competitive and
     suitable product which is acceptable to the end customer. The intent is to
     allow both parties the flexibility of conducting business on a non-
     exclusive basis, other than for the specified Teamed Programs delineated in
     Paragraph 3.0.
