Dear Sirs

OVERDRAFT AND OTHER FACILITIES

We Lloyds TSB Bank plc (the “Bank”) are pleased to continue to offer to Evans & Sutherland Computer Limited a US dollars overdraft facility on accounts numbered 11119338 AND 11397885 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 US$2,500,000.

Availability

The Bank’s present intention is to make the facility available until 31st December 2004 and 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 Bank may, nevertheless, terminate the facility at any time and may, at such time or at any time thereafter, demand immediate payment of all amounts owing under or in connection with the facility. The amounts owing at any time may include interest, costs or charges which have been 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 in US dollars 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 US dollars.

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’ short term offered rate) for US dollars.

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, quarterly in arrears (normally on the 24th of each of February, May, August and November or on the next working day). Interest may also be debited on the date upon which the facility ceases to be available.

	Continuation of a letter from
	Lloyds TSB Bank plc to:
	Evans & Sutherland Computer
	Limited

The Bank’s short term offered rate for US dollars may vary from day to day and upon request the Bank will advise you of the rate then applicable.

Interest will be calculated on the basis of the actual number of days elapsed and a 360 day year.

Costs and Charges

Transaction charges will be payable on each account quarterly in accordance with the Bank’s Standard Business Tariff, a copy of which has already been provided to you. We will be pleased to forward a further copy of the tariff leaflet if one is required. In addition further charges will be payable for other services provided, as shown in the tariff leaflet or as otherwise advised by the Bank from time to time.

These charges will be debited to the relevant account. Charges may be varied by the Bank at any time and notice of changes will be advised to you.

A renewal fee of $18,750 is payable. This will be debited to account number 01232434 in the next few days.

All costs and expenses incurred by the Bank in preserving or enforcing the security referred to below shall be debited to account number 01232434 under advice to you.

Security

It is a condition of the facility (and of the other facilities referred to below) that amounts owing shall be secured by the following.

(a) an all moneys guarantee dated 14th June 2000 from Evans & Sutherland Computer Corporation for a principal amount of £5,000,000 plus interest and other costs as detailed in the guarantee,

(b) a Letter of Negative Pledge dated 19th June 2000 from the Company, and

It is also a condition of the BIGs facility detailed in the Schedule of Other Facilities that the liability outstanding at any time be secured by a deposit agreement incorporating a charge dated 6^th November 2000 from the Company over cash deposits in an aggregate amount equal to such liability outstanding at the relevant time.

Financial Information

Whilst the facility and/or any of the other facilities remain 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 information that the Bank may from time to time reasonably request, including:

(a) your audited annual accounts within 7 months of the end of your financial year,

(b) your monthly management accounts within 30 days of the end of each month, and

(d) the annual 10-K report of Evans & Sutherland Computer Corporation within 4 months of the end of their financial year.

You should also provide to the Bank, at least 10 days prior to the commencement of each quarter, a copy of your cashflow and budget for the quarter then commencing.

Other Facilities

In addition to the overdraft facility we are pleased to offer to you the facilities detailed in the Schedule of Other Facilities. Except when reference is made to another agreement, each additional facility will be available upon such terms and conditions as shall from time to time be specified by the Bank. The facilities may be cancelled by the Bank at any time, but it is the Bank’s present intention to keep the facilities in place for the period of availability of the overdraft facility and your liability in respect of any utilisation may extend beyond such period of availability.

Amounts outstanding in connection with the indemnity line, the negotiations facility, and the TravelLink facility may be in sterling and/or any other currency. For the purpose of determining whether there is sufficient availability within the specified limit for any particular utilisation, amounts outstanding in a currency other than sterling shall be notionally converted into sterling on the date of the proposed utilisation on the basis of the rate at which the Bank would sell the relevant currency for sterling at that time.

If upon termination of the overdraft facility (or earlier cancellation of any of these additional facilities) there are any contingent liabilities existing under or in connection with these additional facilities an amount equal to the value of such contingent liabilities shall, upon any request from the Bank, be deposited with the Bank with the intent that such deposit shall be held by the Bank as security for those liabilities and that such documentation and other things (including the payment of any associated costs) as the Bank may require in order to perfect such security shall be completed.

For the purposes of the above, 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 in connection with any of these additional facilities in a currency other than sterling 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 the sterling amount then owing.

The Bank may debit any amount owing in connection with these additional facilities to your account with the Bank whether or not that would cause the account to become overdrawn or the agreed overdraft limit on the account to be breached.

Other Terms of Offer

This letter is for the benefit of the contracting parties only and shall not confer any benefit on or be enforceable by a third party.

Please confirm your acceptance of the facilities offered by returning the attached duplicate of this letter with the acknowledgement signed in accordance with the bank mandate currently held by the Bank. If such confirmation is not received by the Bank (at the address given at the heading of this letter) by 8th April 2004 the offer will lapse.

Yours faithfully

For and on behalf of Lloyds TSB Bank plc

SCHEDULE OF OTHER FACILITIES

The following additional facilities are available:

1 an indemnity line of £500,000 to cover bonds, indemnities and guarantees (“BIGs”) issued by the Bank or its correspondents on your behalf. The total value of all BIGs that may be outstanding at any one time may not exceed the limit detailed above.

Please note that the total liability of the Bank under certain customs and excise guarantees is twice the amount quoted on the guarantee.

The Bank shall be under no obligation to issue any BIG unless the terms of the BIG and the expiry date of the BIG (or means by which the Bank can terminate its liability) are acceptable to the Bank. The Bank is to be indemnified to its complete satisfaction for its liability in connection with each BIG issued.

2 a negotiations facility of £1,000,000 to cover the negotiation by the Bank of cheques and bills of exchange payable abroad with recourse to you. The limit detailed above is the maximum total amount of proceeds paid to you in respect of cheques and bills of exchange which the Bank anticipates at any point in time may be unpaid by the drawer thereof. For this purpose the Bank will assume payment after 30 days if not actually advised of payment or non-payment, but this shall not prejudice the Bank’s right of recourse to you (and the right of the Bank to debit any unpaid amount to your account with the Bank and to re-calculate any interest on the account as if such amount had never been credited to the account) if advice of non-payment is received at any time thereafter.

3 an open credit facility of £6,000 to cover arrangements to cash your cheques at other banks or at branches of the Bank other than the account holding branch. The limit detailed above is the maximum value of cheques that may be cashed during such periods as may from time to time be advised by the Bank. The limit is currently available as follows:

£3,000 on any one day at Preston Branch.

£3,000 on any one day at Roffey Branch.

4 a BACS facility of £175,000 to cover computerised sterling payment instructions that may be delivered direct by you or through an agreed intermediary to BACS Limited. The limit detailed above is the maximum total value of such instructions for payment during any one month.

5 a LloydsLink payments facility under and subject to the terms and conditions set out in a separate agreement to cover the transfer of funds from agreed accounts by automated means initiated by you. The following limit applies to the facility:

£400,000; the maximum total value of LloydsLink transactions that have been initiated through the PC Pay module, but have not been debited to the agreed accounts (“three day value payments”).

6 a TravelLink facility of £5,000 under and subject to the terms and conditions set out in an agreement dated 31st December 2000 to cover foreign currency and travellers cheques ordered from the Bank by automated means initiated by you. The above limit is the maximum aggregate value of such orders that may be made on any two consecutive business days.
