Dear Sirs

OVERDRAFT FACILITY

We Lloyds TSB Bank plc (the  "Bank") are pleased to offer to Evans &  Sutherland
Computer  Limited an overdraft  facility in such foreign  currencies and on such
accounts  as we may  from  time  to  time  agree  on  the  following  terms  and
conditions.

Amount
The  maximum  aggregate  amount  outstanding  under  the  facility  at any  time
(calculated  on the basis of  cleared  funds)  shall not  exceed  USD  3,000,000
although  prior to 1st August 2000 excesses will be permitted  provided that the
maximum aggregate amount owing at any time does not exceed USD 5,000,000.

For the  purpose  of  determining  whether  the  total  amount  owing  is at any
particular  time  within or in excess of the agreed  limit,  amounts  owing in a
currency other than US Dollars shall be notionally  converted into US Dollars on
the basis of the Bank's  exchange  rate for buying that currency with US Dollars
at that time.

Availability
Any amounts from time to time owing under the  facility are  repayable on demand
but it is the Bank's present intention to make the facility available until 30th
November 2000. All moneys from time to time owing to the Bank under the facility
shall be repaid no later  than this date or such  later date as may from time to
time be  advised  in  writing  by the Bank.  The  amounts  owing at any time may
include  interest or costs  debited to one or more of the accounts in accordance
with the terms of this letter.

The Bank  shall  have the  right at the  time of  making  demand  or at any time
thereafter  to convert all amounts then due and payable  under the facility into
sterling at the Bank's exchange rate for selling that currency  against sterling
at that time.  The Bank shall as soon as possible after such  conversion  advise
you of the sterling amount then owing.

Interest
Interest is  calculated on the cleared daily balance of each account and will be
payable on amounts owing up to the  aforesaid  limit at 1.75% per annum over the
Bank's  short term  offered  rate from time to time for the  relevant  currency.

Lloyds TSB Bank plc to:
Evans & Sutherland Computer Limited

                                       2

If at any time the Bank  allows the  amounts  owing to exceed the agreed  limit,
interest  will be  payable on the  excess at the  Bank's  unauthorised  currency
borrowing  rate from time to time  (currently  12% per  annum  above the  Bank's
relevant  short term offered  rate) for such  currency or currencies as the Bank
shall determine.

Interest  will be debited to the  relevant  account  or, in the case of interest
calculated in  accordance  with the previous  paragraph,  to such account as the
Bank shall determine, semi-annually in arrears (normally on the l0th of June and
December).  Interest  may also be debited  on the date upon  which the  facility
ceases to be available.

The Bank's short term  offered  rate for each  currency may vary from day to day
and upon request the Bank will advise you of the rates then applicable.

Interest  will be  calculated  on the basis of the actual number of days elapsed
and a 360 day  year or a 365 day  year as is in the  Bank's  reasonable  opinion
usual market practice for the relevant  currency.

Costs and Charges
A 30 sterling pound semi-annual charges will be payable on each currency account
in March and September.

An  arrangement  fee of USD 11,250 is payable.  This will be debited to your USD
account number 11119338 in the next few days.

All costs and expenses incurred by the Bank in creating, preserving or enforcing
the security  referred to below shall be debited to.

Security
It is a condition  of the facility  that  amounts  owing shall be secured by the
following.  Any security  which is not already in place is to be provided to the
Bank in a form acceptable to the Bank and, if so requested by the Bank, shall be
accompanied  by evidence of the value of the  security.  (a) an all moneys joint

principal  amount of USD 5,000,000  plus interest and other costs as detailed in
the guarantee, (b) a letter of negative pledge from you, (c) a letter of set off
dated  23rd April 1996 from you,  and (d) a standby  letter of credit  dated 2nd

Financial  Information
Whilst the facility remains  available you should provide to the Bank as soon as
possible  after  the end of the  period  to  which  they  relate  copies  of any
financial  infom1ation  that the Bank may from time to time reasonably  request,
including.  (a) your audited annual  accounts within 210 days of the end of your
