                               EVANS & SUTHERLAND
                      1995 LONG-TERM INCENTIVE EQUITY PLAN

1.  Purpose

    This 1995 Long-Term Incentive Equity Plan (the "Plan") is intended to
promote the long-term success of Evans & Sutherland (the "Company") by providing
its officers and other employees with incentives to create excellent performance
and to continue in the employ of the Company, its subsidiaries, and affiliates.
By encouraging Plan participants to become shareholders of the Company and by
providing actual ownership through Plan awards, it is also intended that
participants will view the Company from an ownership perspective.

2.  Term

    The Plan shall terminate at the close of business on the fifth anniversary
of its approval by the Company's shareholders. After termination of the Plan, no
future awards may be granted but previously granted awards shall remain
outstanding in accordance with their applicable terms and conditions and the
terms and conditions of the Plan.

3.  Plan Administration

    A Committee (the "Committee") appointed by the Board shall be responsible
for administering the Plan. The Committee shall be comprised of persons, in such
numbers as the rules reference herein shall require at any given time, who shall
qualify to administer the Plan as contemplated by (a) Rule 16b-3 under the
Securities and Exchange Act of 1934 (the "1934 Act"), as now or hereafter
applicable to the Company, or any successor rules; and (b) Section 162(m) of the
Internal Revenue Code of 1986, as amended (the "Code"). The Committee shall have
full and exclusive power to interpret the Plan and to adopt such rules,
regulations and guidelines for carrying out the Plan as it may deem necessary or
proper, all of which power shall be executed in the best interests of the
Company and in keeping with the objectives of the Plan. This power includes but
is not limited to selecting award recipients, establishing all award terms and
conditions and adopting modifications, amendments and procedures, including
those contemplated by Section 15 of the Plan, as well as rules and regulations
governing awards under the Plan, and to make all other determinations necessary
or advisable for the administration of the Plan.

4. Eligibility

    Any employee of the Company shall be eligible to receive one or more awards
under the Plan. "Employee" shall also include any former employee of the Company
eligible to receive an assumed or replacement award as contemplated in Sections
5 and 8, and "Company" includes any entity that is directly or indirectly
controlled by the Company or any entity in which the Company has a significant
equity interest, as determined by the Committee.

5.  Shares of Common Stock Subject to the Plan

    Subject to the provisions of Section 6 of the Plan, the aggregate number of
shares of Common Stock ($.20 par value) of the Company ("shares") which may be
transferred to participants under the Plan shall be 350,000, plus any shares
available for grant on the date the Plan is approved by the Company's
shareholders, and any shares which subsequently become available to the extent
that outstanding stock options are terminated or canceled

                                       1
<PAGE>
 
under the Company's 1985 Stock Option Plan for Key Employees and the 1981 Stock
Bonus Plan (the "Prior Plans"). The aggregate number of shares that may be
issued under awards pursuant to Section 8(c) of the Plan and the aggregate
number of shares that may be covered by awards granted to any single individual
under the Plan shall not exceed 283,000 shares. The aggregate number of shares
that may be represented by incentive stock options ("ISOs") intended to comply
with Section 422 of the Code shall not exceed 850,000.

    Shares subject to awards under the Plan, which expire, terminate or are
canceled without exercise or vesting shall thereafter be available for the
granting of other awards. Any shares tendered, either actually or by
attestation, by a person as full or partial payment made to the Company, on or
after the effective date of the Plan in connection with any exercise of a stock
option or receipt of shares under the Plan or Prior Plans shall again be
available for grants under the Plan. Further, in instances where a stock
appreciation right ("SAR") or other award is settled in cash, the shares covered
by such award shall remain available for issuance under the Plan. Likewise, the
payment of cash dividends and dividend equivalents paid in cash in conjunction
with outstanding awards shall not be counted against the shares available for
issuance. Any shares that are issued by the Company, and any awards that are
granted through the assumption, or in substitution for, outstanding awards
previously granted by an acquired entity shall not be counted against the shares
available for issuance under the Plan.

    Any shares issued under the Plan may consist in whole or in part of
authorized and unissued shares or of treasury shares, and no fractional shares
shall be issued under the Plan. Cash may be paid in lieu of any fractional
shares in settlements of awards under the Plan.

6.  Adjustments and Reorganizations

    In the event of any stock dividend, stock split, combination or exchange of
shares, merger, consolidation, spin-off, recapitalization or other distribution
(other than normal cash dividends) of Company assets to shareholders, or any
other change affecting shares or share price, such proportionate adjustments, if
any, as the Committee in its discretion may deem appropriate to reflect such
change shall be made with respect to (a) the aggregate number of shares that may
be issued under the Plan, (b) each outstanding award made under the Plan, and
(c) the exercise price per share for any outstanding stock options, SARs or
similar awards under the Plan.

    In the event that the Company undergoes a change in control (as defined by
the Committee), or is liquidated or reorganized, or is not the surviving company
in a merger or consolidation with another company, and in the absence of the
surviving Company's assumption of outstanding awards made under the Plan, the
Committee may provide for appropriate adjustments, including the acceleration of
vesting, and settlements of such awards either at the time of award or at a
subsequent date.

7.  Fair Market Value

    Fair Market Value for all purposes under the Plan shall mean the closing
price of a share as reported daily in the Wall Street Journal or similar readily
available public source for the date in question. If no sales of shares were
made on such date, the closing price of a share as reported for the preceding
day on which sales of shares were made shall be used.

8.   Awards

    The Committee shall determine the type or types of award(s) to be made to
each participant. Awards may be granted singly, in combination or in tandem.
Awards also may

                                       2
<PAGE>
 
be made in combination or in tandem with, in replacement of, as alternatives 
to, or as the payment form for grants or rights under any other employee or 
compensation plan of the Company including the plan of any acquired entity. The
types of awards that may granted under the Plan are:

a)  Stock Options -- This is a grant of a right to purchase a specified number
    of shares during a specified period as determined by the Committee. The
    purchase price per share for each stock option shall be not less than 100%
    of Fair Market Value on the date of grant, except if a stock option is
    granted retroactively in tandem with or as a substitution for a SAR, the
    exercise price may be no lower than the Fair Market Value of a share on the
    date the SAR was granted. A stock option may be in the form of an ISO which,
    in addition to being subject to applicable terms, conditions and limitations
    established by the Committee, complies with Section 422 of the Code. The
    price at which shares may be purchased under a stock option shall be paid in
    full at the time of the exercise in cash or such other method permitted by
    the Committee, include (i) tendering (either actually or by attestation)
    shares, (ii) surrendering a stock award valued at Fair Market Value on the
    date of surrender, (iii) authorizing a third party to sell the shares (or a
    sufficient portion thereof) acquired upon exercise of a stock option and
    assigning the delivery to the Company of a sufficient amount of the sale
    proceeds to pay for all the shares acquired through such exercise, or (iv)
    any combination of the above.

    The Committee may grant stock options that provide for the award of a new
    stock option when the exercise price has been paid for by tendering shares
    to the Company. Such a stock option shall be limited to the number of shares
    tendered, with the stock option purchase price set at the then-current Fair
    Market Value, and shall not extend beyond the remaining term of the
    originally exercised option.

b)  SARs -- This is a right to receive a payment, in cash and/or shares, equal
    to the excess of the Fair Market Value of a specified number of shares on
    the date the SAR is exercised over the Fair Market Value on the date the SAR
    was granted as set forth in the applicable award agreement. Except if a SAR
    is granted retroactively in tandem with or in substitution for a stock
    option, the designated Fair Market Value in the applicable award agreement
    for the date of grant shall be no lower than the actual Fair Market Value of
    a share on such date of grant.

c)  Stock Awards -- This is an award made or denominated in shares or units
    equivalent in value to shares. All or part of any stock award may be subject
    to conditions and restrictions established by the Committee, and set forth
    in the award agreement, which may include but are not limited to continuous
    service with the Company, achievement of specific business objectives and
    other measurements of individual, business unit or Company performance.

9.  Dividends and Dividend Equivalents

    The Committee may provide that any awards under the Plan earn dividends or
dividend equivalents. Such dividends or dividend equivalents may be paid
currently or may be credited to a participant's account. Any crediting of
dividends or dividend equivalents may be subject to such restrictions and
conditions as the Committee may establish, including reinvestment in additional
shares or share equivalents.

10. Deferrals and Settlements

    Payment of awards may be in the form of cash, stock, other awards or
combinations thereof as the Committee shall determine, and with such
restrictions as it may impose. The Committee also may require or permit
participants to elect to defer the issuance of shares or the settlement of
awards in cash under such rules and procedures as it may establish under the
Plan. It also may provide that deferred settlements include the payment or
crediting of interest on the deferral amounts, or the payment or crediting of
dividend equivalents where the deferral amounts are denominated in shares.

11. Transferability and Exercisability

    Awards granted under the Plan shall be nontransferable or assignable other
than by will or the laws of descent and distribution, except that the Committee
may provide for the transferability of particular awards: (a) by gift or other
transfer of an award to (i) any trust or estate in which the original award
recipient or such participant's spouse or other immediate relative has a
substantial beneficial interest or (ii) a spouse or other immediate relative;
and (b) pursuant to a qualified domestic relations order (as defined by the
Code). However, any award so transferred shall continue to be subject to all the
terms and conditions contained in the instrument evidencing such award.

    In the event that a participant terminates employment with the Company to
assume a position with a governmental, charitable, educational or similar non-
profit institution, the Committee may subsequently authorize a third party,
including but not limited to a "blind" trust, to act on behalf of and for the
benefit of such participant regarding any outstanding awards held by the
participant subsequent to such termination of employment. If so permitted by the
Committee, a participant may designate a beneficiary or beneficiaries to
exercise the rights of the participant and receive any distribution under the
Plan upon the death of the participant.

12. Award Agreements

    Awards under the Plan shall be evidenced by agreements that set forth the
terms, conditions and limitations for each award which may include the term of
an award (except that in no event shall the term of any ISO exceed a period of
ten years from the date of its grant), the provisions applicable in the event
the participant's employment terminates, and the Company's authority to
unilaterally or bilaterally amend, modify, suspend, cancel or rescind any award.
The Committee need not require the execution of any such agreement, in which
case acceptance of the award by the participant shall constitute agreement to
the terms of the award.

13. Foreign Participation

    In order to assure the viability of awards granted to participants employed
in foreign countries, the Committee may provide for such special terms as it may
consider necessary or appropriate to accommodate differences in local law, tax
policy, or custom. Moreover, the Committee may approve such supplements to, or
amendments, restatements or alternative versions of the Plan as it may consider
necessary or appropriate for such purposes without thereby affecting the terms
of the Plan as in effect for any other purpose; provided, however, that no such
supplements, amendments, restatements or alternative versions shall increase the
share limitations contained in Section 5 of the Plan.

14. Plan Amendment

    The Plan may be amended by the Committee as it deems necessary or
appropriate to better achieve the purposes of the Plan, except that no such
amendment which would increase the number of shares available for issuance in
accordance with Sections 5 and 6 of the Plan or cause the Plan not to comply
with Rule16b-3 (or any successor rule) under the 1934 Act or Section 162(m) of
the Code shall be made without the approval of the Company's shareholders.

15. Tax Withholding

    The Company shall have the right to deduct from any settlement of an award
made under the Plan, including the delivery or vesting of shares, a sufficient
amount to cover withholding of any federal, state or local taxes required by
law, or to take such other action as may be necessary to satisfy any such
withholding obligations. The Committee may permit shares to be used to satisfy
required tax withholding and such shares shall be valued at the Fair Market
Value as of the settlement date of the applicable award.

16. Other Benefit and Compensation Programs

    Unless otherwise specifically determined by the Committee, settlements of
awards received by participants under the Plan shall not be deemed a part of a
participant's regular, recurring compensation for purposes of calculating
payments or benefits from any Company benefit plan, severance program or
severance pay law of any country. Further, the Company may adopt other
compensation programs, plans or arrangements as it deems appropriate or
necessary.

17. Unfunded Plan

    Unless otherwise determined by the Committee, the Plan shall be unfunded and
shall not create (or be construed to create) a trust or a separate fund or
funds. The Plan shall not establish any fiduciary relationship between the
Company and any participant or other person. To the extent any person holds any
rights by virtue of a grant awarded under the Plan, such rights (unless
otherwise determined by the Committee) shall be no greater than the rights of an
unsecured general creditor of the Company.

18. Use of Proceeds

    The cash proceeds received by the Company from the issuance of shares
pursuant to awards under the Plan shall be used for general corporate purposes.

19. Regulatory Approvals

    The implementation of the Plan, the granting of any award under the Plan,
and the issuance of shares upon the exercise or settlement of any award shall be
subject to the Company's procurement of all approvals and permits required by
regulatory authorities having jurisdiction over the Plan, the awards granted
under it or the shares issued pursuant to it.

20. Future Rights

    No person shall have any claim or rights to be granted an award under the
Plan, and no participant shall have any rights under the Plan to be retained in
the employ of the Company.

                                       5

21. Governing Law

    The validity, construction and effect of the Plan and any actions taken or
relating to the Plan shall be determined in accordance with the laws of the
State of Utah and applicable federal law.

22. Successors and Assigns

    The Plan shall be binding on all successors and assigns of a participant,
including, without limitation, the estate of such participant and the executor,
administrator or trustee of such estate, or any receiver or trustee in
bankruptcy or representative of the participant's creditors.

liabilities which arise from or with respect to the Purchased Assets or the
operation of the Business and are incurred in or attributable to the Pre-Closing
Tax Period, the non-payment of which would result in a Lien on any Purchased
Asset, would otherwise adversely affect the Business or would result in Buyer
becoming liable therefor.

    8.03. Tax Cooperation; Allocation of Taxes.
          ------------------------------------

    (a) Each Party agrees to furnish or cause to be furnished to the other
Parties, upon request, as promptly as practicable, such information and
assistance relating to the Purchased Assets and the Business as is reasonably
necessary for the filing of all Tax returns, and making of any election related
to Taxes, the preparation for any audit by any taxing authority, and the
prosecution or defense of any claim, suit or proceeding relating to any Tax
return. Each Party shall cooperate with the other Parties in the conduct of any
audit or other proceeding related to Taxes involving the Business and each shall
execute and deliver such powers of attorney and other documents as are necessary
to carry out the intent of this paragraph (a) of Section 8.03.

    (b)   All personal property taxes and similar ad valorem obligations levied
                                                  -- -------
with respect to the Purchased Assets for a taxable period which includes (but
does not end on) the Closing Date (collectively, the "Apportioned Obligations")
shall be apportioned between Seller and its Subsidiaries, on the one hand, and
Buyer, on the other hand, as of the Closing Date based on the number of days of
such taxable period included in the Pre-Closing Tax Period and the number of
days of such taxable period included in the Post-Closing Tax period. Seller
shall be liable for the amount of such taxes that is attributable to the Pre-
Closing Tax Period. Within 30 days after the Closing, Seller and Buyer shall
present a statement to the other setting forth the amount of reimbursement to
which each is entitled under this Section 8.03 (b) together with

                                     -26 -
<PAGE>
 
such supporting evidence as is reasonably necessary to calculate the proration
amount. The proration amount shall be paid by the Party owing it to the other
within 10 days after delivery of such statement. Thereafter, Seller shall notify
Buyer upon receipt of any bill for personal property taxes relating to the
Purchased Assets, part or all of which are attributable to the Post-Closing Tax
Period, and shall promptly deliver such bill to Buyer who shall pay the same to
the appropriate taxing authority, provided that if such bill covers the
Pre-Closing Tax Period, Seller shall also remit prior to the due date of payment
to Buyer payment for the amount of such bill that is attributable to the Pre-
Closing Tax Period. If either Seller or Buyer shall thereafter make a payment
for which it is entitled to reimbursement under this Section 8.03(b), the other
Party shall make such reimbursement promptly but in no event later than 30
days after presentation of a statement setting forth the amount of reimbursement
to which the presenting Party is entitled along with such supporting evidence as
is reasonably necessary to calculate the amount of reimbursement. Any payment
required under this Section 8.03(b) and not made within 30 days of delivery of
the statement shall bear interest at the rate per annum determined, from time to
time, under the provisions of law related to the late payment of the tax in
question for each day until paid.

    (c)   Any transfer, documentary, sales or use Taxes assessed upon the
transfer of the Purchased Assets to Buyer and any recording or filing fees with
respect thereto shall be shared equally by Seller and Buyer.

Plan or Benefit Arrangement which would increase the expense of maintaining such
Employee Plan or Benefit Arrangement above the level of the expense incurred in
respect thereof for the most recent fiscal year.

commence such engagements with Buyer are hereinafter collectively referred to as
the "Hired Consultants". Seller will not take any action that would impede,
     -----------------

policy previously provided to Buyer, provided, however, that for purposes of
                                     --------- --------
determining the amount of severance benefits to which a Hired Employee would be
entitled pursuant to this sentence and to Parent's vacation policies, such Hired
Employee shall be credited with his or her prior service with Seller. In
addition, as soon as practicable after the Closing Date, management of Parent
shall use reasonable efforts to obtain the approval of Parent's Board of
Directors for the waiver of the waiting period for the Hired Employees with
respect to Parent's employee stock purchase plan as in effect on the Closing
Date. The employees who accept and commence employment with Buyer are
hereinafter collectively referred to as the "Hired Employees". Seller will not
take any action that would impede, hinder, interfere or otherwise compete with
Buyer's effort to hire any Hired Employees. Buyer shall not assume
responsibility for any Hired Employee until such employee commences employment
with Buyer.

        11.04.  Procedures; No Waiver.
                ---------------------
        (a)     The Party seeking indemnification under Section 11.02 (the 
"Indemnified Party") agrees to give prompt notice to the Party against whom 
 -----------------
indemnity is sought (the "Indemnifying Party") of the assertion of any claim, 
                          ------------------
or the commencement of any suit, action or proceeding in respect of which 
indemnity may be sought under such Section. The Indemnifying Party may, and at 
the request of the Indemnified Party shall, participate in and control the 
defense of any such suit, action of proceeding at its own expense; provided, 
that if any claim against or affecting Buyer by a Person who is not a Party 
which seeks damages in excess of Seller's indemnification obligation as 
described in Section 11.03(b)(ii), Buyer shall have the right to control the

be liable hereunder for any settlement or compromise effected without its
consent of any claim, litigation or proceeding in respect of which indemnity may
be sought hereunder, which consent shall not be unreasonably withheld or
delayed.

        (b)     If Seller used its best efforts to comply with a closing 
condition but is unable so to comply, and Buyer elects to waive such 
compliance, such waiver of such closing condition by Buyer shall limit their 
rights under Section 11.02 solely with respect to the matter waived.

        (c)     If the Indemnifying Party disputes its liability with respect 
to such claim or demand or the amount thereof (whether or not the Indemnifying 
Party desires to defend the

submitted to mediation in accordance with Section 13.09 hereof. Pending the
resolution of any dispute by the Indemnifying Party of its liability with
respect to any claim or demand, such claim or demand shall not be settled 
without the prior written consent of the Indemnifying Party, such consent not 
to be unreasonably withheld or delayed.

arising in connection with or relating to this Agreement or the making,

                             PATENT ASSIGNMENT AND

        This Agreement effective _______________, 1995, is made by and between 
Panametric Technology Corporation, a Massachusetts corporation (hereinafter, 
together with all subsidiary and affiliate companies which it now or hereinafter
owns or controls, "PTC"), and Evans & Sutherland Computer Corporation, a Utah 
corporation ("E&S").  

        WHEREAS, E&S and PTC are Parties to a certain Asset Purchase Agreement 
(the "Purchase Agreement") relating to the purchase and sale of certain assets 
of the Design Software Division of E&S, including the sale and assignment of 
Proprietary Rights (as defined in the Purchase Agreement);

        WHEREAS, the Parties desire to effect the assignment by E&S to PTC 
pursuant to the Purchase Agreement of all claims of all United States patents 
and all patent applications set forth in Appendix A to this Agreement, together 
                                         ----------
with any division, continuation, continuation-in-part, extension, revival and 
reissue thereof or any substitution therefor, and all corresponding patents and 
patent applications in other countries (the "Assigned Patents and Patent 
Rights"); and 

        WHEREAS, E&S has requested, and PTC desires to grant to E&S, a license 
under the Assigned Patents and Patent Rights, as well as a license to certain 
software included in the Proprietary Rights, such licenses to be limited in 
scope as set forth herein.

        NOW, THEREFORE, in consideration of the foregoing and of the mutual 
promises and covenants contained in this Agreement and in the Purchase
Agreement, in which this Agreement is incorporated and made a part, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, PTC and E&S hereby agree as follows:

        1.      Definitions.  The following terms shall have the meaning set 
                -----------
forth below.  Terms not otherwise defined herein shall have the meaning 
ascribed to them in the Purchase Agreement.

                "Exclusive Field of Use" means the design, development, 
                 ----------------------
modification, reproduction, use, distribution, sale, license and support of 
software products for applications consisting of mechanical (A) computer-aided 
engineering, design and manufacturing, (B) computer-aided styling and industrial
design and (C) kinematics and structural and thermal dynamics.  The Exclusive 
Field of Use shall also include any extensions of the foregoing that may develop
after the Closing as a result of general changes in the markets for such 
products.  

                "Restricted Field of Use" means the design, development, 
                 -----------------------
modification, reproduction, use, distribution, sale, license and support of 
hardware and software products for E&S's current simulation, graphics, 
entertainment and visualization businesses (other than those in the Exclusive 
Field of Use).  The Restricted Field of Use shall also include any
<PAGE>
 
                                     - 2 -


extensions of the foregoing that may develop after the Closing as a result of 
general changes in the markets for such products.

                "Licensed Software" means the CDRS and 3D Paint software, 
                 -----------------
including any and all copyrights therein, included in the Proprietary Rights and
conveyed by E&S to PTC pursuant to the Purchase Agreement.  For purposes of this
Agreement, the Licensed Software includes both source and object code for such 
software and supporting documentation therefor, such as code listings, 
flowcharts, schematics and programmer's notes, in each case as the same exist on
the Closing Date.

        2.      Assignment of Patent Rights.  E&S hereby assigns, remedies and 
                ---------------------------
releases unto PTC all right, title, interest, claim and demand in and to the 
Assigned Patents and Patent Rights.  For a period of two years following the 
Closing Date, PTC shall not, without the prior written consent of E&S, use or 
practice the Assigned Patents and Patent Rights within the Restricted Field of
Use. Notwithstanding the foregoing, PTC shall not be deemed to be in violation
of the preceding sentence if it shall use or practice the Assigned Patents and
Patent Rights in products that contain features or functionality that fall
within the Restricted Field of Use, provided that the resulting products are not
competitive with products of E&S within the Restricted Field of Use existing at
the Closing Date (including those products acquired by PTC pursuant to the
Purchase Agreement).

        3.      Grant-Back Patent License.  PTC hereby grants E&S a fully paid,

non-exclusive, perpetual, irrevocable, worldwide license to make, use, sell and 
offer to sell devices, methods, processes and products embodying the Assigned 
Patents and Patent Rights or any claimed elements thereof (or their 
equivalents), and otherwise to use and practice the Assigned Patents and Patent 
Rights, provided, however, that E&S shall not use or practice the Assigned 
Patents and Patent Rights within the Exclusive Field of Use.  Notwithstanding 
the foregoing, E&S shall not be deemed to be in violation of the foregoing 
sentence if it shall use the assigned Patents and Patent Rights in products that
contain features or functionality that fall within the Exclusive Field of Use, 
provided that the resulting products are not competitive with products of PTC 
within the Exclusive Field of Use existing at the Closing Date.  The license 
granted herein shall be effective for the life of the subject Assigned Patents 
and Patent Rights and shall terminate on the expiration date of the last of the 
subject Assigned Patents and Patent Rights to expire.  E&S shall not sublicense 
any rights granted hereunder for any purpose within the Exclusive Field of Use, 
but may do so in any other field of use.  

        4.      Software License.  PTC hereby grants to E&S a fully paid, 
                ----------------
perpetual, non-exclusive, worldwide right and license, but not within the 
Exclusive Field of Use, to use, modify, copy, execute, reproduce, sell, 
distribute, display and perform the Licensed Software or portions thereof, to 
port, translate and convert the Licensed Software or portions thereof to execute
on any operating platform, and to prepare products and works of authorship
(including "derivative works" within the meaning of such term in the Copyright
Act, 17 U.S.C. Section 101 et seq.) using, based on, derived from or
incorporating the Licensed Software or portions thereof. The foregoing grant of

<PAGE>
 
        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,

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

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

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.

     Teamed Programs:

     F16 Egypt WTT
     F16 Taiwan WTT

4.0  PARTIES INTENT
     --------------

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.

     services as a subcontractor to E&S.

4.3  DURATION OF MOA

     either party may reasonably request) to discuss market business issues with
     respect to selling of visual systems. Such discussions shall address recent
     successes and failures in the market, future potential opportunities, new
     markets to be jointly pursued, as well as the consideration of new products
     to be jointly developed in pursuit of new markets, and any other areas of
     general concern regarding the markets served.

B)   The parties hereto recognize the importance of the sharing of information
     for the marketing of visual systems and their integration into total
     training systems solutions. To that end, each party shall use its best
     efforts to provide accurate information to the other with respect to
     activities within the scope of the MOA and to protect the proprietary
     information of the other.

6.0  SUPPORT

                         ELIGIBILITY AND PARTICIPATION
                         -----------------------------

3.1.  GENERAL.
      --------

    This Plan is intended to be a "top hat plan" for purposes of the Act and, as
a result, the Plan will be unfunded and participation in the Plan shall be
limited to a "select group of management or highly compensated employees". From
this "select group", the compensation committee of the Board (the "Compensation
Committee") shall designate the Employees who are eligible to participate in
this Plan. All such designations shall be in the Compensation Committee's
unfettered discretion and no Employee shall have the right to participate in
this Plan until the Employee has been designated as an eligible Employee by the
Compensation Committee.

3.2.  APPLICATION TO PARTICIPATE.
      ---------------------------

    Each Employee who is designated as eligible to participate in the Plan by
the Compensation Committee may become a Participant by completing and signing an
enrollment form provided by, or acceptable to, the Plan Administrator and
delivering the form to the Plan Administrator. The Employee shall designate on
the form the amount of his Participant Deferrals and shall authorize the
reduction of his Earnings in an amount equal to his Participant Deferrals.

3.3.  TIMING OF PARTICIPATION.
      ------------------------

    After an Employee has been selected by the Compensation Committee to
participate in the Plan, the Employee will have 30 days to notify the Plan
Administrator whether he will participate in the Plan. If the Employee timely
notifies the Plan Administrator of his intent to participate in the Plan, the
Employee's participation will commence the first day of the calendar month after
the Plan Administrator is so notified. If the Employee does not timely notify
the Plan Administrator of his intent to participate in the Plan, the Employee
may commence participation as of the first day of any later Plan Year by
notifying the Plan Administrator prior to the first day of such Plan Year.

3.4.  DISCONTINUANCE OF PARTICIPATION.
      --------------------------------

      Once an Employee is designated as eligible to participate, he will remain
eligible for all future Plan Years unless the Compensation Committee
specifically discontinues his eligibility. In the exercise of its discretion,
the Compensation Committee may elect to discontinue an Employee's participation
in the Plan at any time and for any or no reason. If an Employee's participation
in the Plan is discontinued, the Employee will no longer be eligible to make
Participant Deferrals or to receive Matching Contributions. The Employee will
not be entitled to receive a distribution from his accounts, however, until the
occurrence of one of the events listed in Sections 8.1 through 8.5.
Notwithstanding the preceding sentence, the Plan Administrator, in its
discretion, may allow for the earlier distribution of the Participant's accounts
pursuant to Section 8.4.

              --------
during each Plan Year while he is a Participant. The amount payable to the
Participant as his current salary or wages shall then be reduced by an amount
equal to the Participant Deferrals. On the election form, the Participant may
designate different deferral percentages or amounts for different forms of
Earnings (e.g., base salary as opposed to bonuses). Participant Deferrals shall
be directed in a specified dollar amount or in whole percentage increments of
the type of Earnings to which the election relates.

      (b)     LIMITATIONS. A Participant shall not be permitted to make annual
              -----------
Participant Deferrals during in Plan Year in excess of ten percent (10%) of his
Earnings during such Plan Year. The Plan Administrator may adopt other limits
on the amount of Participant Deferrals in accordance with such uniform rules as
it may adopt from time to time.

4.2.  DESIGNATION AND CHANGE OF DESIGNATION OF PARTICIPANT
      ----------------------------------------------------
      DEFERRALS.
      ---------

      All designations or changes of designation of the amount of Participant
Deferrals to be elected shall be made on forms supplied by, or acceptable to,
the Plan Administrator, signed by the Participant and delivered to the Plan
Administrator. A designation shall be effective as of the first day of the next
Plan Year. A payroll deduction designation form shall be effective until it is
succeeded by another valid payroll deduction designation form or until the
Participant's right to make Participant Deferrals is otherwise suspended or
terminated.

Contribution on behalf of each eligible Participant in an amount equal to fifty
percent (50%) of the Participant's Participant Deferrals for the Plan Year;
provided, however, that Participant Deferrals in excess of 6% of the
Participant's Earnings shall be disregarded for this purpose. For the Plan Year

eligible Participant in any amount it so determines.

5.2.  ELIGIBLE PARTICIPANTS.
      ----------------------

    A separate Participant Deferral Account and a separate Matching Contribution
Account will be maintained for each Participant. Each account will be adjusted
as provided in this Article Six to reflect the crediting of interest at the
Interest Rate applicable for the Plan Year, the addition of Participant
Deferrals or Matching Contributions, and any distributions. The accounts are
bookkeeping accounts only.

6.3.  INTEREST.
      ---------

    As of each Valuation Date, the Plan Administrator shall credit interest at
the Interest Rate applicable for that Plan Year to the Matching Contributions
Accounts and the Participant Deferral Accounts. Interest will be credited on the
"adjusted account balance". For this purpose, the "adjusted account balance" is
the account balance as of the immediately preceding Valuation Date, plus (in the
case of the Participant Deferral Account) 50% of the Participant Deferrals made
since such Valuation Date, minus any withdrawals or distributions charged to the
account since the prior Valuation Date. The amount of interest to be credited
shall be prorated in a uniform manner if the period of time since the last
Valuation Date is less than one year.

6.4.  CHANGE OF CONTROL.
      ------------------

    Notwithstanding anything in this Plan to the contrary, in the event of a
Change of Control, the Employer shall immediately transfer to the Trust Fund an
amount of cash equal to the balance credited to each Participant's Matching
Contribution Account and Participant Deferrals Account as of the Change of
Control. Thereafter, the Employer shall contribute to the Trust Fund any
Participant Deferrals and Matching Contributions made by Participants and the
Employer after the Change of Control and such amounts shall be credited with the
applicable Interest Rate.

the manner provided in Sections 8.6 and 8.7.

    (b)     DEATH AFTER COMMENCEMENT OF BENEFITS. In the event that a former
            --------------------------------------                          
Participant shall die after the day on which his benefit payments commence, but
prior to the complete distribution of all amounts to which such Participant is
entitled under the provisions of this ARTICLE EIGHT, the Participant's
designated Beneficiary shall be entitled to receive any remaining amounts to
which the Participant would have been entitled had the Participant survived. The
Plan Administrator may require and rely upon such proofs of death and the right
of any Beneficiary to receive benefits pursuant to this Section 8.3 as the Plan
Administrator may reasonably determine, and its determination of death and the
right of such Beneficiary to receive payment shall be binding and conclusive
upon all persons whomsoever.

8.4.  OTHER SEPARATIONS FROM EMPLOYMENT.
      ----------------------------------

    A Participant who separates from employment for any reason, including
termination of employment following a Change in Control, but other than for
retirement, death, or Disability shall be entitled to distribution of his vested
interest in his accounts at the time and in the manner provided in Sections 8.6
and 8.7. In the exercise of its discretion, the Plan Administrator may also
elect to commence distributions while the Participant is employed if the
Participant's participation has been discontinued pursuant to Section 3.4.

8.5.  HARDSHIP DISTRIBUTIONS.
      -----------------------

    (a)     GENERAL RULE. A Participant or former Participant may request that a
            --------------                                                      
distribution of amounts credited to his Participant Deferrals Accounts be made
on the basis of hardship.

    (b)     LIMITATION ON DISTRIBUTIONS. In no event shall a hardship
            -----------------------------                            
distribution exceed the balance of the Participant's or former Participant's
Participant Deferrals Account, determined as of the Valuation Date immediately
preceding the date of the distribution, less any amounts distributed from or
charged to the Participant Deferrals Account since such Valuation Date. The Plan
Administrator may promulgate uniform rules regarding the effective date of any
distribution, minimum amounts to be distributed and the frequency of
distributions.

    (c)     HARDSHIP DEFINED. A distribution may be made pursuant to this
            ------------------                                           
Section due to a "hardship" only if the Participant satisfies the Plan
Administrator that the

                                       10
<PAGE>
 
Participant has an immediate and heavy financial need and that the distribution
is necessary in order to satisfy that need.

    (d)     IMMEDIATE AND HEAVY FINANCIAL NEED. The existence of an immediate
            ------------------------------------                             
and heavy financial need shall be determined on the basis of all of the relevant
facts and circumstances. As a general rule, a financial need shall not be deemed
to be immediate unless the expenses involved must be paid within sixty (60) days
from the date on which the request for the hardship distribution is being
considered. Also, as a general rule, a financial need shall not be considered to
be "heavy" unless the expenses exceed five percent (5%) of the Participant's
Earnings for the Plan Year prior to the P[an Year in which the request for the
hardship distribution is made. In addition, a hardship distribution may be made
only if the "need" that gives rise to the distribution request is for funeral
expenses of a spouse or lineal ascendant or descendant of the Participant, the
educational expenses of the Participant, the Participant's spouse, children or
descendants, or one of the reasons listed in subparagraphs (1) through (5) of
this paragraph (d), or some of the reasons periodically authorized in written
procedures or rules adopted by the Plan Administrator and communicated to the
Participants. A financial need shall not fail to qualify as immediate and heavy
merely because such need was reasonably foreseeable or voluntarily incurred by
the Participant. The following expenses or circumstances will be deemed to give
rise to an immediate and heavy financial need for purposes of this Section
regardless of whether the general standards set out above are satisfied:

        (1)    Medical expenses described in Section 213(d) of the Code incurred
     by the Participant, the Participant's spouse, or any dependents (as defined
     in Section 152 of the Code) of the Participant; or

        (2)    The purchase (excluding mortgage payments) of a principal
     residence for the Participant; or

        (3)    Payment of tuition, related educational fees and room and board
     expenses for the next year of post-secondary education for the Participant
     or the Participant's spouse, children or dependents; or

        (4)    The need to prevent the eviction of the Participant from his
     principal residence or foreclosure on the mortgage on the Participant's
     principal residence; or

        (5)    Any other circumstance or expense designated by the Commissioner
     of Internal Revenue as a deemed immediate and heavy financial need in any
     published revenue ruling, notice, or other document of general
     applicability.

The Plan Administrator may rely on any representations made by the Participant
concerning the Participant's intended use of funds distributed to the
Participant pursuant to this Section, the urgency of any intended expenditures
or any other relevant matters.

                                       11
<PAGE>
 
    (e)     NECESSITY. A distribution will be considered to be necessary to
            -----------                                                    
satisfy an immediate and heavy financial need of a Participant only if the need
may not be satisfied from other resources that are reasonably available to the
Participant and the distribution does not exceed the amount needed to satisfy
the need. The Plan Administrator shall consider all relevant facts and
circumstances in determining whether a hardship distribution is necessary in
order to satisfy an immediate and heavy financial need. Generally, a
distribution shall be deemed necessary if the Participant represents to the Plan
Administrator that the need cannot be relieved through reimbursement or
compensation by insurance or otherwise, by the reasonable liquidation of the
Participant's assets (to the extent that such liquidation would not itself cause
an immediate and heavy financial need), by cessation of elective pre-tax
contributions or after-tax contributions under any plan sponsored by the
Employer, or by other distributions or nontaxable loans under any Plan sponsored
by the Employer. A distribution will be deemed to be necessary to satisfy an
immediate and heavy financial need of a Participant if all of the following
requirements are satisfied, regardless of whether the general standards set
forth above are met:

    (1)    The distribution is not in excess of the amount of the immediate and
heavy financial need of the Participant; and

    (2)    The Participant has obtained all distributions, other than hardship
distributions, and all nontaxable loans currently available under all plans
maintained by the Employer.

The Plan Administrator may rely upon any representations made by the Participant
pursuant to this paragraph.

8.6.  TIME OF DISTRIBUTION OF BENEFITS.
      ---------------------------------

    (a)     RETIREMENT. Payment to a Participant who is entitled to benefits
            ------------                                                    
under Section 8.1 normally shall commence within a reasonable time following the
year-end Valuation Date next following the Participant's termination of
employment.

    (b)     TERMINATION AND DISABILITY. Payment to a Participant who is entitled
            ----------------------------                                        
to benefits under Section 8.2 or Section 8.4 shall commence as soon as possible
after the year-end Valuation Date next following the Participant's termination
of employment.

    (c)     DEATH AFTER COMMENCEMENT OF PAYMENTS. In the event of the death of a
            --------------------------------------                              
Participant after the day on which his benefit payments commence but prior to
the complete distribution to such Participant of the benefits payable to him
under the Plan, any remaining benefits shall be distributed over a period that
does not exceed the period over which distribution was to be made prior to the
date of death of the Participant. Payments to the Beneficiaries entitled to
payments pursuant to Section 8.3 shall commence as soon as possible following
the death of the Participant.

                                       12
<PAGE>
 
    (d)     DEATH PRIOR TO COMMENCEMENT OF BENEFITS. In the event of the death
            -----------------------------------------                         
of the Participant prior to the day on which his benefit payments commence,
payments to the Participant's Beneficiary shall commence as soon as possible
following the Participant's death.

8.7.  METHOD OF DISTRIBUTION.
      -----------------------

    Unless a Participant requests a different distribution schedule and the Plan
Administrator, in its discretion, agrees to such proposed distribution,
distributions shall be made in one lump sum. If distributions are made in
installments, the remaining balance of the Participant's accounts will be
credited with interest in accordance with Section 6.3. The Plan Administrator,
in the exercise of its discretion, may elect to accelerate the distributions if
an installment payment option has been elected. The election made by the
Participant shall apply to all payments to the Participant or his Beneficiary.

8.8.  DESIGNATION OF BENEFICIARY.
      ---------------------------

    Each Participant shall have the right to designate, on forms supplied by, or
acceptable to, and delivered to the Plan Administrator, a Beneficiary or
Beneficiaries to receive his benefits hereunder in the event of the
Participant's death. For each Participant who is married, his Beneficiary shall
be deemed to be his spouse, unless the Participant's spouse consents to the
Participant's Beneficiary designation to the contrary. Such consent must be in
writing, must acknowledge the effect of the beneficiary designation and the
spouse's consent thereto. Subject to the foregoing, each Participant may change
his Beneficiary designation from time to time in the manner described above.
Upon receipt of such designation by the Plan Administrator, such designation or
change of designation shall become effective as of the date of the notice,
whether or not the Participant is living at the time the notice is received.
There shall be no liability on the part of the Employer, the Plan Administrator
or the Trustee with respect to any payment authorized by the Plan Administrator
in accordance with the most recent valid Beneficiary designation of the
Participant in its possession before receipt of a more recent and valid
Beneficiary designation. If no designated Beneficiary is living when benefits
become payable, or if there is no designated Beneficiary, the Beneficiary shall
be the Participant's spouse; or if no spouse is then living, such Participant's
issue, including any legally adopted child or children, in equal shares by right
of representation; or if no such designated Beneficiary and no such spouse or
issue, including any legally adopted child or children, is living upon the death
of a Participant, or if all such persons die prior to the full distribution of
such Participant's benefits, then the Beneficiary shall be the estate of the
Participant.

8.9.  PAYMENTS TO DISABLED.
      ---------------------

    If a person entitled to any payment hereunder shall be under a legal
disability, or in the sole judgment of the Plan Administrator shall otherwise be
unable to apply such payment to his own interest and advantage, the Plan
Administrator in the exercise of its discretion may make any such payment in any
one (1) or more of the following ways: (a) directly to such person, (b) to his
legal guardian or conservator, or (c) to his spouse or to any

                                       13
<PAGE>
 
person charged with the legal duty of his support, to be expended for his
benefit. The decision of the Plan Administrator shall in each case be final and
binding upon all persons in interest.

   8.10.  UNDERPAYMENT OR OVERPAYMENT OF BENEFITS.
          ----------------------------------------

    In the event that, through misstatement or computation error, benefits are
underpaid or overpaid, there shall be no liability for any more than the correct
benefit sums under the Plan. Overpayments may be deducted from future payments
under the Plan, and underpayments may be added to future payments under the
Plan. In lieu of receiving reduced benefits under the Plan, a Participant or
beneficiary may elect to make a lump sum repayment of any overpayment.

                          INALIENABILITY OF BENEFITS
                          --------------------------

9.1.  NO ASSIGNMENT PERMITTED.
      ------------------------

    (a)     GENERAL PROHIBITION. No Participant or Beneficiary, and no creditor
            ---------------------                                              
of a Participant or Beneficiary, shall have any right to assign, pledge,
hypothecate, anticipate, or in any way create a lien upon the Plan or the Trust
Fund. All payments to be made to Participants or their Beneficiaries shall be
made only upon their personal receipt or endorsement, except as provided in
Section 8.8, and no interest in the Plan or the Trust Fund shall be subject to
assignment or transfer or otherwise be alienable, either by voluntary or
involuntary act or by operation of law or equity, or subject to attachment,
execution, garnishment, sequestration, levy, or other seizure under any legal,
equitable or other process, or be liable in any way for the debts or defaults of
Participants and Beneficiaries.

    (b)     PERMITTED ARRANGEMENTS. This Section shall not preclude arrangements
            ------------------------                                            
for the withholding of taxes from benefit payments, arrangements for the
recovery of benefit overpayments, arrangements for the transfer of benefit
rights to another plan, or arrangements for direct deposit of benefit payments
to an account in a bank, savings and loan association or credit union (provided
that such arrangement is not part of an arrangement constituting an assignment
or alienation). Additionally, this Section shall not preclude arrangements for
the distribution of the benefits of a Participant or Beneficiary pursuant to the
terms and provisions of a "qualified domestic relations order" in accordance
with the following provisions of this ARTICLE NINE.

9.2.  QUALIFIED DOMESTIC RELATIONS ORDERS.
      ------------------------------------

    A "qualified domestic relations order" is an order described in Section
206(d)(3) of the Act that permits distribution of benefits in a distribution
mode provided under the Plan, does not require payment of increased benefits and
does not require payment of benefits allocated to a different alternate payee
under a prior qualified domestic relations order.

                                       14
<PAGE>
 
9.3.  PROCESSING QUALIFIED DOMESTIC RELATIONS ORDERS.
      -----------------------------------------------

    (a)     NOTICE. All decisions and determinations with respect to a domestic
            --------                                                           
relations order, including whether such order is a qualified domestic relations
order within the meaning of Section 206(d)(3) of the Act, shall be made by the
Plan Administrator within a reasonable time following its receipt of such order
and in accordance with such uniform and nondiscriminatory rules and procedures
as may be adopted by the Plan Administrator. Upon receipt of a domestic
relations order, the Plan Administrator shall notify the Participant or
Beneficiary whose benefits may be affected by such order of its receipt of such
order. The Plan Administrator shall also advise the Participant or Beneficiary
and the alternate payee named in the order of its rules and procedures relating
to the determination of the qualified status of such order.

    (b)     RETENTION OF PAYMENTS. If payment of benefits to the Participant or
            -----------------------                                            
Beneficiary has commenced at the time a domestic relations order is received by
the Plan Administrator or benefits become payable after receipt of such order,
the Plan Administrator shall segregate and hold the amounts which would be
payable to the alternate payee under the order if such order is ultimately
determined to be a qualified domestic relations order. If the Plan Administrator
determines that the order is a qualified domestic relations order within
eighteen (18) months of the segregation of benefits payable to the alternate
payee under such order, the Plan Administrator shall pay the segregated amounts
(plus any earnings thereon) as well as such future amounts as may be specified
in such order to the alternate payee. If the Plan Administrator determines that
the order is not a qualified domestic relations order or is unable to determine
whether such order is a qualified domestic relations order within the eighteen
(18) month period following the segregation of benefits, the Plan Administrator
shall pay the segregated amounts (plus any earnings thereon) to the Participant
or Beneficiary. A determination by the Plan Administrator after the close of
such eighteen (18) month period that the order is a qualified domestic relations
order shall be applied prospectively. All determinations of the Plan
Administrator hereunder with respect to the status of an order as a qualified
domestic relations order shall be binding and conclusive on all interested
parties, subject to the provisions of Section 10.4.

10.2.  ALLOCATION OF FIDUCIARY RESPONSIBILITY.
       ---------------------------------------

    The Plan Administrator is the named fiduciary with respect to the
administration of the Plan. It shall not be responsible for any fiduciary
functions or other duties assigned to the Trustee pursuant to this Plan or the
Trust Agreement.

10.3.  POWERS OF THE PLAN ADMINISTRATOR.
       ---------------------------------

    (a)     GENERAL POWERS. The Plan Administrator shall have the power and
            ----------------                                               
discretion to perform the administrative duties described in this Plan or
required for proper administration of the Plan and shall have all powers
necessary to enable it to properly carry out such duties. Without limiting the
generality of the foregoing, the Plan Administrator shall have the power and
discretion to construe and interpret this Plan, to hear and resolve claims
relating to this Plan, and to decide all questions and disputes arising under
this Plan. The Plan Administrator shall determine, in its discretion, the
service credited to the Employees, the status and rights of a Participant, and
the identity of the Beneficiary or Beneficiaries entitled to receive any
benefits payable hereunder on account of the death of a Participant.

    (b)     BENEFIT PAYMENTS. Except as is otherwise provided hereunder, the
            ------------------                                              
Plan Administrator shall determine the manner and time of payment of benefits
under this Plan. All benefit disbursements by the Trustee shall be made upon the
instructions of the Plan Administrator.

    (c)     DECISIONS FINAL. The decision of the Plan Administrator upon all
            -----------------                                               
matters within the scope of its authority shall be binding and conclusive upon
all persons.

    (d)     REPORTING AND DISCLOSURE. The Plan Administrator shall file all
            --------------------------                                     
reports and forms lawfully required to be filed by the Plan Administrator with
any governmental agency or department, federal or state, and shall distribute
any forms, reports, statements or plan descriptions lawfully required to be
distributed to Participants and others by any governmental agency or department,
federal or state.

10.4.  CLAIMS.
       -------

    (a)     FILING OF CLAIM. A Participant or Beneficiary entitled to benefits
            -----------------                                                 
need not file a written claim to receive benefits. If an Employee, Participant,
Beneficiary, or any other person is dissatisfied with the determination of his
benefits, eligibility, participation, or any other right or interest under this
Plan, such person may file a written statement setting forth the basis of the
claim with the Plan Administrator in a manner prescribed by the Plan
Administrator. In connection with the determination of a claim, or in connection
with review of a denied claim, the claimant may examine this Plan and any other
pertinent documents generally available to Participants relating to the claim
and may submit comments in writing.

                                       16
<PAGE>
 
    (b)     NOTICE OF DECISION. A written notice of the disposition of any such
            --------------------                                               
claim shall be furnished to the claimant within thirty (30) days after the claim
is filed with the Plan Administrator, provided that the Plan Administrator may
have an additional period to decide the claim if it advises the claimant in
writing of the need for an extension and the date on which it expects to decide
the claim. The notice of disposition of a claim shall refer, if appropriate, to
pertinent provisions of this Plan, shall set forth in writing the reasons for
denial of the claim if the claim is denied (including references to any
pertinent provisions of this Plan), and where appropriate shall explain how the
claimant can perfect the claim.

    (c)     REVIEW. If the claim is denied, in whole or in part, the claimant
            --------                                                         
shall also be notified in writing that a review procedure is available.
Thereafter, within ninety (90) days after receiving the written notice of the
Plan Administrator's disposition of the claim, the claimant may request in
writing, and shall be entitled to, a review meeting with the Plan Administrator
to present reasons why the claim should be allowed. The claimant shall be
entitled to be represented by counsel at the review meeting. The claimant also
may submit a written statement of his claim and the reasons for granting the
claim. Such statement may be submitted in addition to, or in lieu of, the review
meeting with the Plan Administrator. The Plan Administrator shall have the right
to request of and receive from a claimant such additional information,
documents, or other evidence as the Plan Administrator may reasonably require.
If the claimant does not request a review meeting within ninety (90) days after
receiving written notice of the Plan Administrator's disposition of the claim,
the claimant shall be deemed to have accepted the Plan Administrator's written
disposition, unless the claimant shall have been physically or mentally
incapacitated so as to be unable to request review within the ninety (90) day
period.

    (d)     DECISION FOLLOWING REVIEW. A decision on review shall be rendered in
            ---------------------------                                         
writing by the Plan Administrator ordinarily not later than sixty (60) days
after review, and a written copy of such decision shall be delivered to the
claimant. If special circumstances require an extension of the ordinary period,
the Plan Administrator shall so notify the claimant. In any event, if a claim is
not determined within one hundred twenty (120) days after submission for review,
it shall be deemed to be denied.

    (e)     DECISIONS FINAL; PROCEDURES MANDATORY. To the extent permitted by
            ---------------------------------------                          
law, a decision on review by the Plan Administrator shall be binding and
conclusive upon all persons whomsoever. To the extent permitted by law,
completion of the claims procedures described in this Section shall be a
mandatory precondition that must be complied with prior to commencement of a
legal or equitable action in connection with the Plan by a person claiming
rights under the Plan or by another person claiming rights through such a
person. The Plan Administrator may, in its sole discretion, waive these
procedures as a mandatory precondition to such an action.

10.5.  CREATION OF COMMITTEE.
       ----------------------

    The Employer may appoint a committee to perform its duties as Plan
Administrator by the adoption of appropriate Board resolutions. The committee
shall consist of at least two (2) members, and they shall hold office during the
pleasure of the Board. The

                                       17
<PAGE>
 
committee members shall serve without compensation but shall be reimbursed for
all expenses by the Employer. The committee shall conduct itself in accordance
with the provisions of this ARTICLE TEN. The members of the committee may resign
with thirty (30) days notice in writing to the Employer and may be removed
immediately at any time by written notice from the Employer.

10.6.  CHAIRMAN AND SECRETARY.
       -----------------------

    The committee shall elect a chairman from among its members and shall select
a secretary who is not required to be a member of the committee and who may be
authorized to execute any document or documents on behalf of the committee. The
secretary of the committee or his designee shall record all acts and
determinations of the committee and shall preserve and retain custody of all
such records, together with such other documents as may be necessary for the
administration of this Plan or as may be required by law.

10.7.  APPOINTMENT OF AGENTS.
       ----------------------

    The committee may appoint such other agents, who need not be members of the
committee, as it may deem necessary for the effective performance of its duties,
whether ministerial or discretionary, as the committee may deem expedient or
appropriate. The compensation of any agents who are not Employees of the
Employer shall be fixed by the committee within any limitations set by the
Board.

10.8.  MAJORITY VOTE AND EXECUTION OF INSTRUMENTS.
       -------------------------------------------

    In all matters, questions, and decisions, the action of the committee shall
be determined by a majority vote of its members. They may meet informally or
take any ordinary action without the necessity of meeting as a group. All
instruments executed by the committee shall be executed by a majority of its
members or by any member of the committee designated to act on its behalf.

10.9.  ALLOCATION OF RESPONSIBILITIES AMONG COMMITTEE MEMBERS.
       -------------------------------------------------------

    The committee may allocate responsibilities among its members or designate
other persons to act on its behalf. Any allocation or designation, however, must
be set forth in writing and must be retained in the permanent records of the
committee.

10.10.  CONFLICT OF INTEREST.
        ---------------------

    No member of the committee who is a Participant shall take any part in any
action in connection with his participation as an individual. Such action shall
be voted or decided by the remaining members of the committee.

10.11.  OTHER FIDUCIARY CAPACITIES.

inapplicable. If and so long as any two (2) members of the committee also serve

                            SCOPE OF RESPONSIBILITY
                            -----------------------

11.1.  SCOPE OF RESPONSIBILITY.
       ------------------------

    (a)     GENERAL. The Employer, the Plan Administrator and the Trustee shall
            ---------                                                          
perform the duties respectively assigned to them under this Plan and the Trust
Agreement and shall not be responsible for performing duties assigned to others
under the terms and provisions of this Plan or the Trust Agreement. No inference
of approval or disapproval is to be made from the inaction of any party
described above or the employee or agent of any of them with regard to the
action of any other such party. Persons, organizations, or corporations acting
in a position of any fiduciary responsibility with respect to the Plan or the
Trust Fund may serve in more than one fiduciary capacity.

    (b)     ADVISORS. The Employer, the Plan Administrator, and the Trustee
            ----------                                                     
shall have authority to employ advisors, legal counsel, and accountants in
connection with the administration of the Plan and the Trust Fund, as set forth
in the Trust Agreement. To the extent permitted by applicable law, the Employer,
the Plan Administrator, and the Trustee shall not be liable for complying with
the directions of any advisors, legal counsel, or accountants appointed pursuant
to this Plan or the Trust Agreement.

    (c)     INDEMNIFICATION. To the extent permitted by law, the Employer shall
            -----------------                                                  
and does hereby jointly and severally indemnify and agree to hold harmless its
employees, officers, and directors who serve in fiduciary capacities with
respect to the Plan and the Trust Agreement from all loss, damage, or liability,
joint or several, including payment of expenses in connection with defense
against any such claim, for their acts, omissions, and conduct, and for the
acts, omissions, and conduct of their duly appointed agents, which acts,
omissions, or conduct constitute or are alleged to constitute a breach of such
individual's fiduciary or other responsibilities under the Act or any other law,
except for those acts, omissions, or conduct resulting from his own willful
misconduct, willful failure to act, or gross negligence; provided, however, that
if any party would otherwise be entitled to indemnification hereunder in respect
of any liability and such party shall be insured against loss as a result of
such liability by any insurance contract or contracts, such party shall be

                                       19
<PAGE>
 
entitled to indemnification hereunder only to the extent by which the amount of
such liability shall exceed the amount thereof payable under such insurance
contract or contracts.

                                ARTICLE TWELVE
                                --------------
                       AMENDMENT, MERGER AND TERMINATION
                       ---------------------------------

12.1.  AMENDMENT.
       ----------

    The Employer shall have the right at any time, by an instrument in writing
duly executed, acknowledged and delivered to the Plan Administrator and the
Trustee, to modify, alter or amend this Plan, in whole or in part, prospectively
or retroactively; provided, however, that the duties and liabilities of the Plan
Administrator and the Trustee hereunder shall not be substantially increased
without their written consent; and provided further that the amendment shall not
reduce any Participant's interest in the Plan, calculated as of the date on
which the amendment is adopted. If the Plan is amended by the Board after it is
adopted by an Affiliate, unless otherwise expressly provided, it shall be
treated as so amended by such Affiliate without the necessity of any action on
the part of the Affiliate.

12.2.  MERGER OR CONSOLIDATION OF EMPLOYER.
       ------------------------------------

    The Plan shall not be automatically terminated by the Employer's acquisition
by or merger into any other employer, but the Plan shall be continued after such
acquisition or merger if the successor employer elects and agrees to continue
the Plan and to become a party to the Trust Agreement. All rights to amend,
modify, suspend, or terminate the Plan shall be transferred to the successor
employer, effective as of the date of the merger and provided specifically that
the successor employer shall not have the right to amend the Plan to reduce any
Participant's interest in the Plan, calculated as of the date on which any
amendment is adopted.

12.3.  TERMINATION OF PLAN OR DISCONTINUANCE OF CONTRIBUTIONS.
       -------------------------------------------------------

    It is the expectation of the Employer that this Plan and the payment of
contributions hereunder will be continued indefinitely. However, continuance of
the Plan is not assumed as a contractual obligation of the Employer, and the
right is reserved at any time to terminate this Plan or to reduce, temporarily
suspend, or discontinue contributions hereunder, provided that any such
termination, reduction, suspension, or discontinuance of contributions shall not
reduce any Participant's interest in the Plan, calculated as of the date such
action is taken.

12.4.  LIMITATION OF EMPLOYER LIABILITY.
       ---------------------------------

    The adoption of this Plan is strictly a voluntary undertaking on the part of
the Employer and shall not be deemed to constitute a contract between the
Employer and any Employee or Participant or to be consideration for, an
inducement to, or a condition of the

                                       20
<PAGE>
 
employment of any Employee. A Participant, Employee, or Beneficiary shall not
have any right to retirement or other benefits except to the extent provided
herein.

                               ARTICLE THIRTEEN
                               ----------------
                              GENERAL PROVISIONS
                              ------------------

13.1.  LIMITATION ON PARTICIPANTS' RIGHTS.
       -----------------------------------

    Participation in the Plan shall not give any Employee the right to be
retained in the Employer's employ or any right or interest under the Plan or in
the Trust Fund other than as herein provided. The Employer reserves the right to
dismiss any Employee without any liability for any claim either under the Plan
or against the Trust Fund, except to the extent herein provided, or against the
Employer.

13.2.  STATUS OF PARTICIPANTS AS UNSECURED CREDITORS.
       ----------------------------------------------

    All benefits under the Plan shall be unsecured obligations of the Employer
and, except for the assets placed in the Trust Fund as provided in this Plan, no
assets of the Employer will be segregated from the general assets of the
Employer for the payment of benefits under this Plan. To the extent that any
person acquires the right to receive payments under this Plan, such right shall
be no greater than the right of any unsecured general creditor of the Company.

13.3.  STATUS OF TRUST FUND.
       ---------------------

    The Trust Fund is being established to assist the Employer in meeting its
obligations to the Participants and to provide the Participants with a measure
of protection in certain limited instances. In certain circumstances described
in the Trust Agreement, the assets of the Trust Fund will be used for the
benefit of the Employer's creditors. Benefit payments due under this Plan shall
either be paid from the Trust Fund or from the Employer's general assets as
directed by the Employer.

13.4.  UNIFORM ADMINISTRATION.
       -----------------------

    Whenever in the administration of the Plan any action is required by the
Plan Administrator, such action shall be uniform in nature as applied to all
persons similarly situated.

13.5.  HEIRS AND SUCCESSORS.
       ---------------------

    All of the provisions of this Plan shall be binding upon all persons who
shall be entitled to any benefits hereunder, and their heirs and legal
representatives.

13.6.  EMPLOYER-OWNED LIFE INSURANCE.
       ------------------------------

    (a)     EMPLOYER OWNS ALL RIGHTS. In the event that, in its discretion, the
            --------------------------                                         
Employer purchases a life insurance policy or policies insuring the life of any
Participant to allow the Employer to informally finance and/or recover, in whole
or in part, the cost of providing benefits under this Plan, neither the
Participant nor any Beneficiary shall have any rights whatsoever in such policy
or policies. The Employer shall be the sole owner and beneficiary of any such
policy or policies and shall possess and may exercise all incidents of
ownership, except in the event that the Employer establishes and transfers such
policy or policies to the Trust Fund.

    (b)     PARTICIPANT COOPERATION. If the Employer decides to purchase a life
            -------------------------                                          
insurance policy or policies on any Participant, the Employer will so notify
each Participant. Each Participant shall consent to being insured for the
benefit of the Employer and shall take whatever actions may be necessary to
enable the Employer to timely apply for and acquire such life insurance and to
fulfil the requirements of the insurance carrier relative to the issuance
thereof as a condition of eligibility to participate in the Plan.

    IN WITNESS WHEREOF, the Employer has caused this Plan to be executed by its
duly authorized representative on this __ day of _____________, 1995.

        DEFINITIONS. When a word or phrase shall appear in this Plan with the

date two years prior to such change.

    2.7      "COMPANY" means Evans & Sutherland. Computer Corporation, a Utah

            -----------------------                                            
who need not be members of the committee, as it may deem necessary for the
effective performance of its duties, whether ministerial or discretionary, as
the committee may deem expedient or appropriate. The compensation of any agents
who are not employees of the Company shall be fixed by the committee within any
limitations set by the Board.

    10.8    MAJORITY VOTE AND EXECUTION OF INSTRUMENTS. In all matters,
            --------------------------------------------               
questions, and decisions, the action of the committee shall be determined by a
majority vote of its members. They may meet informally or take any ordinary
action without the necessity of meeting as a group. All instruments executed by
the committee shall be executed by a majority of its members or by any member of
the committee designated to act on its behalf.

    10.9    ALLOCATION OF RESPONSIBILITIES AMONG COMMITTEE MEMBERS. The
            --------------------------------------------------------

persons to act on its behalf. Any allocation or designation, however, must be
set forth in writing and must be retained in the permanent records of the
committee.

    10.10 CONFLICT OF INTEREST. No member of the committee who is a Participant
          ----------------------

individual. Such action shall be voted or decided by the remaining members of
the committee.

    10.11    OTHER FIDUCIARY CAPACITIES. The members of the committee may also
             ----------------------------                                     
serve in any other fiduciary capacity, and, specifically, all or some members of
the committee may serve as Trustee. Notwithstanding any other provision of this
Plan, if and so long as any two (2) members of the committee also serve as
Trustee, any provision of this Plan or the Trust Agreement which requires a
direction, certification, notification, or other communication from the Plan
Administrator to the Trustee shall be inapplicable. If and so long as any two
(2) members of the committee also serve as Trustee, any action taken by either
the committee or the Trustee shall be deemed to be taken by the appropriate
party.

    10.12  AUTHORITY TO ESTABLISH A TRUST. The Company shall have the right at
           --------------------------------                                   
any time to establish a trust to which the Company may transfer from time to
time certain assets to be used by the Trustee to satisfy some or all of the
Company's obligations and liabilities under the Plan. All assets held by the
Trust Fund shall be subject to the claims of the Company's creditors in the
event of the Company's Insolvency (as defined in the Trust Agreement).

    10.13  PREPAYMENT. The Plan Administrator may, in its sole and absolute
           ------------                                                    
discretion, prepay all or any part of the monthly installments remaining to be
paid to the Participant or the Beneficiary under this Plan. The amount of such
prepayment shall equal the Actuarial Equivalent of the remaining monthly
installments being prepaid, as determined by the Plan Administrator using an
independent actuary, and receipt thereof by the Participant or Beneficiary shall
be in full satisfaction of all remaining obligations of the Company under the
Plan.

                            SCOPE OF RESPONSIBILITY
                            -----------------------

    11.1  SCOPE OF RESPONSIBILITY.
          ------------------------

    (a)      GENERAL. The Company, the Plan Administrator and the Trustee shall
             ---------                                                         
perform the duties respectively assigned to them under this Plan and the Trust
Agreement and shall not be responsible for performing duties assigned to others
under the terms and provisions of this Plan or the Trust Agreement. No inference
of approval or disapproval is to be made from the inaction of any party
described above or the employee or agent of any of them with regard to the
action of any other such party. Persons, organizations, or corporations acting
in a position of any fiduciary responsibility with respect to the Plan or the
Trust Fund may serve in more than one fiduciary capacity.

    (b)      ADVISORS. The Company, the Plan Administrator, and the Trustee
             ----------                                                    
shall have authority to employ advisors, legal counsel, accountants, and
actuaries in connection with the administration of the Plan and the Trust Fund,
as set forth in the Trust Agreement. To the extent permitted by applicable law,
the Company, the Plan Administrator, and the

                                       11
<PAGE>
 
Trustee shall not be liable for complying with the directions of any advisors,
legal counsel, or accountants appointed pursuant to this Plan or the Trust
Agreement.

    (c)       INDEMNIFICATION. To the extent permitted by law, the Company shall
              -----------------                                                 
and does hereby jointly and severally indemnify and agree to hold harmless its
employees, officers, and directors who serve in fiduciary capacities with
respect to the Plan and the Trust Agreement from all loss, damage, or liability,
joint or several, including payment of expenses in connection with defense
against any such claim, for their acts, omissions, and conduct, and for the
acts, omissions, and conduct of their duly appointed agents, which acts,
omissions, or conduct constitute or are alleged to constitute a breach of such
individual's fiduciary or other responsibilities under ERISA or any other law,
except for those acts, omissions, or conduct resulting from his own willful
misconduct, willful failure to act, or gross negligence; provided, however, that
if any party would otherwise be entitled to indemnification hereunder in respect
of any liability and such party shall be insured against loss as a result of
such liability by any insurance contract or contracts, such party shall be
entitled to indemnification hereunder only to the extent by which the amount of
such liability shall exceed the amount thereof payable under such insurance
contract or contracts.

                                  ARTICLE 12
                                  -----------
                       AMENDMENT, MERGER AND TERMINATION
                       ---------------------------------

    12.1  AMENDMENT.
          ---------
    The Company shall have the right at any time, by an instrument in writing
duly executed, acknowledged and delivered to the Plan Administrator and the
Trustee, to modify, alter or amend this Plan; provided, however, that the duties
and liabilities of the Plan Administrator and the Trustee hereunder shall not be
substantially increased without their written consent; and provided further that
the amendment shall not reduce any Participant's interest in the Plan,
calculated as of the date on which the amendment is adopted.

    12.2  MERGER OR CONSOLIDATION OF COMPANY.
          -----------------------------------
    The Plan shall not be automatically terminated by the Company's acquisition
by or merger into any other employer, but the Plan shall be continued after such
acquisition or merger if the successor employer elects and agrees to continue
the Plan and to become a party to the Trust Agreement. All rights to amend,
modify, suspend, or terminate the Plan shall be transferred to the successor
employer, effective as of the date of the merger and provided specifically that
the successor employer shall not have the right to amend the Plan to reduce any
Participant's interest in the Plan, calculated as of the date on which any
amendment is adopted.

   12.3  TERMINATION OF PLAN OR DISCONTINUANCE OF CONTRIBUTIONS.
         -------------------------------------------------------

    It is the expectation of the Company that this Plan will be continued
indefinitely. However, continuance of the Plan is not assumed as a contractual
obligation of the Company, and the right is reserved at any time to terminate
this Plan or to reduce, temporarily suspend, or discontinue contributions
hereunder, provided that any such termination, reduction, suspension, or
discontinuance of contributions shall not reduce any Participant's interest in
the Plan, calculated as of the date such action is taken.

    12.4  LIMITATION OF COMPANY LIABILITY.
          --------------------------------

    The adoption of this Plan is strictly a voluntary undertaking on the part of
the Company and shall not be deemed to constitute a contract between the Company
and any Employee or Participant or to be consideration for, an inducement to, or
a condition of the employment of any employee. A Participant, employee, or
Beneficiary shall not have any right to retirement or other benefits except to
the extent provided herein.

                                  ARTICLE 13
                                  -----------

                          COMPANY-OWNED LIFE INSURANCE
                          ----------------------------

    13.1     COMPANY OWNS ALL RIGHTS. In the event that, in its discretion, the
             -------------------------                                         
Company purchases a life insurance policy or policies insuring the life of any
Participant to allow the Company to informally finance and/or recover, in whole
or in part, the cost of providing the benefits hereunder, neither the
Participant nor any Beneficiary shall have any rights whatsoever therein. The
Company shall be the sole owner and beneficiary of any such policy or policies
and shall possess and may exercise all incidents of ownership therein, except
that the Company may transfer such policies to the Trust Fund in the event of a
Change of Control.

    13.2     PARTICIPANT COOPERATION. If the Company decides to purchase a life
             -------------------------                                         
insurance policy or policies on any Participant, the Company will so notify each
Participant. Each Participant shall consent to being insured for the benefit of
the Company and shall take whatever actions may be necessary to enable the
Company to timely apply for and acquire such life insurance and to fulfill the
requirements of the insurance carrier relative to the issuance thereof as a
condition of eligibility to participate in the Plan.

    13.3     PARTICIPANT MISREPRESENTATION. If: (a) any Participant is required
             -------------------------------                                   
by this Plan to submit information to any insurance carrier; and (b) the
Participant makes a material misrepresentation in any application for such
insurance; and (c) as a result of that material misrepresentation the insurance
carrier is not required to pay all or any part of the proceeds provided under
that insurance, then the Participant's (or the Participant's Beneficiary's)
rights

                                       13

to any benefits under this Plan may be, at the sole discretion of the Board,
reduced or forfeited.

                                 MISCELLANEOUS
                                 -------------

    14.1     NONALIENATION OF BENEFITS. No right or benefit under this Plan
             ---------------------------                                   
shall be subject to anticipation, alienation, sale, assignment, pledge,
encumbrance, or charge, and any attempt to anticipate, alienate, sell, assign,
pledge, encumber, or charge any right or benefit under this Plan shall be void.
No such right or benefit shall in any manner be liable for or subject to the
debts, contracts, liabilities, or torts of the person entitled thereto.

    14.2     UNSECURED COMPANY LIABILITY. The obligation of the Company to make
             -----------------------------                                     
payments to a Participant under this Plan shall constitute an unsecured
liability of the Company. Such payments shall be made from the general funds of
the Company, and the Company shall not be required to establish or maintain any
special or separate fund, to purchase or acquire life insurance on a
Participant's life, or otherwise to segregate assets to assure that such
payments shall be made. Neither a Participant nor any other person shall have
any interest in any particular asset of the Company by reason of its obligation
hereunder, and the right of any of them to receive payments under this Plan
shall be no greater than the right of any other unsecured general creditor of
the Company.

    14.3     NO EMPLOYMENT AGREEMENT. Neither the execution of this Plan or any
             -------------------------                                         
SERP Agreement nor any other action taken by the Company pursuant to this Plan
shall beheld or construed to confer on a Participant any legal right to be
continued as an employee of the Company or to restrict the right of the Company
to terminate his employment.

    14.4     DESIGNATION OF BENEFICIARY. Each Participant shall file with the
             ----------------------------                                    
Company a notice in writing, in a form acceptable to the Board, designating one
or more Beneficiaries to whom payments becoming due by reason of or after his
death shall be made. Participants shall have the right to change the Beneficiary
or Beneficiaries so designated from time to time; provided, however, that no
such change shall become effective until received in writing and acknowledged by
the Company.

    14.5     PAYMENT TO INCOMPETENTS. The Company shall make the payments
             -------------------------                                   
provided herein directly to the Participant or Beneficiary entitled thereto or,
if such Participant or Beneficiary has been determined by a court of competent
jurisdiction to be mentally or physically incompetent, then payment shall be
made to the duly appointed guardian, committee, or other authorized
representative of such Participant or Beneficiary. The Company shall have the
right to make payment directly to a Participant or Beneficiary until it has
received actual notice of the physical or mental incapacity of such Participant

                                       14

or Beneficiary and actual notice of the appointment of a duly authorized
representative of his estate.

    14.6     BINDING EFFECT. Obligations incurred by the Company pursuant to
             ----------------                                               
this Plan shall be binding upon and inure to the benefit of the Company, its
successors, and assigns, and the Participant, his Beneficiaries, personal
representatives, heirs, and legatees.

    14.7     ENTIRE PLAN. This document and any amendments hereto contain all
             -------------                                                   
the terms and provisions of the Plan and shall constitute the entire Plan, nay
other alleged terms or provisions being of no effect.

    14.8  ENFORCEABILITY. If any term or condition of this Plan shall be invalid
          ----------------                                                      
or unenforceable to any extent or in any application, then the remainder of the
Plan, and such term or condition except to such extent or in such application,
shall to be affected thereby, and each and every term and condition of the Plan
shall be valid and enforced to the fullest extent and in the broadest
application permitted by law.

    15.1     GOVERNING LAW. This Plan shall be construed and governed in
             ---------------                                            
accordance with the laws of the State of Utah to the extent not preempted by
Federal law.

    15.2     GENDER. The masculine gender, where appearing in the Plan, shall be

deemed to include the feminine gender, and the singular may include the plural,
unless the context clearly indicates to the contrary.

    15.3     HEADINGS, ETC. All headings used in this Plan are for convenience
             ---------------
