ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 16-10a-901, et. seq., of the Utah Revised Business Corporation Act
authorizes a court to award, or a corporation's board of directors to grant,
indemnity to directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933.
The E&S Bylaws require E&S to indemnify its directors and officers, including
circumstances in which indemnification is otherwise discretionary under Utah
law. E&S has entered into indemnification agreements with its directors
containing provisions which are in some respects broader than the specific
indemnification provisions contained in Utah law. The indemnification
agreements may require E&S, among other things, to indemnify its directors and
officers against certain liabilities that may arise by reason of their status
or service as directors or officers (other than liabilities arising from
willful misconduct of a culpable nature), to advance their expenses incurred
as a result of any proceeding against them as to which they could be
indemnified, and to obtain director and officer insurance, if available on
reasonable terms. E&S's Articles of Incorporation provide for indemnification
of its directors and officers to the maximum extent permitted by Utah law, and
E&S's Bylaws provide for indemnification of its directors, officers, employees
and other agents as permitted by Utah law.

    Re:  Merger Opinion

Ladies and Gentlemen:

      We have acted as counsel to Evans & Sutherland Computer Corporation, a
Utah corporation ("E&S"), in connection with the Agreement and Plan of Merger
dated April 22, 1998 (the "Agreement") by and among E&S, E&S Merger Corp. a Utah
corporation and wholly-owned subsidiary of E&S ("Merger Sub"), and
AccelGraphics, Inc., a Delaware corporation. Pursuant to the Agreement, AGI will
merge with and into Merger Sub (the "Merger") and Merger Sub will continue to be
a wholly-owned subsidiary of E&S.

      Our opinion regarding certain of the federal income tax consequences of
the Merger is required in connection with the filing with the Securities and
Exchange Commission of a registration statement (the "Registration Statement")
which includes the Joint Proxy Statement-Prospectus relating to the Merger. Our
opinion is also required pursuant to Section 7.01(f) of the Agreement as a
condition to the consummation of the Merger.

      Except as otherwise provided, capitalized terms referred to herein have
the meanings set forth in the Agreement. All section references, unless
otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the
"Code").

      For the purpose of rendering this opinion, we have examined and are
relying upon (without any independent investigation or review thereof) the truth
and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents:
<PAGE>
 
Evans & Sutherland Computer Corporation

Page 2


 
          1.  The Agreement;

          2.  The Registration Statement;

          3.  Representations made to us by E&S and Merger Sub in a Certificate
reproduced as Exhibit A hereto and representations made to us by AGI in a
Certificate reproduced as Exhibit B hereto (collectively the "Tax
Certificates"); and

          4.  Such other instruments and documents related to the formation, 
organization, and operation of AGI, E&S, and Merger Sub, and/or to the 
consummation of the Merger and the transactions contemplated thereby as we have 
deemed necessary or appropriate.

          In connection with rendering this opinion, we have assumed (without 
any independent investigation) that:

          1.  Original documents (including signatures) are authentic, documents
submitted to us as copies conform to the original documents, and there has been
(or will be by the Effective Time of the Merger) due execution and delivery of
all documents where due execution and delivery are prerequisites to
effectiveness thereof;

          2.  Any representation or statement referred to above made "to the 
knowledge of," "to the best of the knowledge," or otherwise similarly qualified 
is correct without such qualification.  As to all matters in which a person or 
entity making a representation referred to above has represented that such 
person or entity either is not a party to, does not have, or is not aware of, 
any plan, intention, understanding or agreement, there is in fact no such plan, 
intention, understanding or agreement;

          3.  All statements, descriptions and representations contained in any 
of the documents referred to herein or otherwise made to us are true and correct
in all material respects and will continue to be true and correct in all 
material respects as of the Effective Time of the Merger and all other relevant 
times, and no actions have been (or will be) taken which are inconsistent with 
such representations;

          4.  The Merger will be reported by E&S and AGI on their respective 
federal income tax returns in a manner consistent with the opinion set forth 
below;

          5.  The Merger will be consummated in accordance with the Agreement 
(and without any waiver, breach or amendment of any of the provisions thereof)
and will be effective under applicable state laws;
<PAGE>
 
Evans & Sutherland Computer Corporation

          6.   The stockholders of AGI will receive in the Merger E&S Common 
Stock having an aggregate fair market value as of the Effective Time that is not
less than 50% of the aggregate fair market value of all consideration received 
by stockholders of AGI in the Merger, and no transactions have occurred or will 
occur following the Effective Time of the Merger that would cause the continuity
of interest requirement as specified in Treasury Regulations Section 1.368-1(e) 
to be violated; and

          7.   The opinion of counsel to be issued by Venture Law Group, A 
Professional Corporation, to AGI has been delivered and not withdrawn.

          Based on our examination of the foregoing items and subject to the 
assumptions, exceptions, limitations, and qualifications set forth herein, we 
are of the opinion that if the Merger is consummated in accordance with the 
Agreement (and without any waiver, breach, or amendment of any of the provisions
thereof) and the statements set forth in the Tax Certificates are true and 
correct as of the Effective Time of the Merger, then, for federal income tax 
purposes, the Merger will qualify as a "reorganization" as defined in Section 
368(a) of the Code and that each of E&S, Merger Sub, and AGI will constitute a 
"party" to the reorganization within the meaning of Section 368(b) of the Code.

          In addition to the assumptions set forth above, this opinion is 
subject to the exceptions, limitations, and qualifications set forth below.

          1. This opinion represents and is based upon our best judgment
regarding the application of federal income tax laws arising under the Code,
existing judicial decisions, administrative regulations, and published rulings
and procedures. Our opinion is not binding upon the Internal Revenue Service or
the courts, and there is no assurance that the Internal Revenue Service will not
successfully assert a contrary position. Furthermore, no assurance can be given
that future legislative, judicial, or administrative changes, on either a
prospective or retroactive basis, would not adversely affect the accuracy of the
conclusions stated herein. Nevertheless, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
federal income tax laws.

          2.   This opinion addresses only the classification of the Merger as a
reorganization under Section 368(a) of the Code and the consequences of the 
Merger as described above, and does not address any other federal or any state, 
local, or foreign tax consequences that
<PAGE>
 
Evans & Sutherland Computer Corporation

may result from the Merger or any other transaction (including any 
transaction undertaken in connection with the Merger).


     3. No opinion is expressed as to any transaction other than the Merger as
described in the Agreement or to any transaction whatsoever, including the
Merger, if all the transactions described in the Agreement are not consummated
in accordance with the terms of the Agreement and without waiver or breach of
any material provision thereof or if all of the representations, warranties,
statements and assumptions upon which we relied are not true and accurate at all
relevant times. In the event any one of the statements, representations,
warranties, or assumptions upon which we have relied to issue this opinion is
incorrect, our opinion might be adversely affected and may not be relied upon.

     4. The opinion set forth herein is intended solely for the purpose of
including this opinion as an exhibit to the Registration Statement and is
intended solely for your benefit. It may not be relied upon for any other
purpose or by any other person or entity, and may not be made available to any
other person or entity without our prior written consent. We hereby consent to
the filing of this opinion as an exhibit to the Registration Statement and to
the use of our name under the heading "Material Federal Income Tax
Consequences."


                                            Yours truly,
