</TABLE>

(1)  Based upon the closing price of the common stock of the Company on June 30,
     1998, which price was $3.50 per share.

DIRECTOR COMPENSATION

     The Company does not pay any annual retainer or per meeting fees to its
directors, other than to Mr. John Forrest, who also served as an outside 
director of LSI.  Mr. Forrest is compensated at a rate of approximately $33,000 
annually.  The Company reimburses all of the directors for their out-of-pocket
expenses in connection with performing their duties as directors of the Company.
In addition, each non-employee director is granted options under the Directors'
Stock Option Plan to purchase shares of common stock.  In November 1997, Mr.
Rynearson and a former director, David Irwin, each received a grant under this
plan of 8,500 immediately vested options at an exercise price of $6.06 per
share.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
              
     Prior to the combination, the Compensation Committee of the
Company's Board of Directors consisted of Mr. Sam Smith, who was appointed as
Interim Chief Executive Officer of the Company on June 30, 1997, and Mr. David 
Irwin, until his resignation from his position as a director in February 1998.
Although the Company paid consultancy fees to Mr. Smith for his role as Interim
Chief Executive Officer, he was not at any time during the fiscal year ended
June 30, 1998, an employee of the Company. Upon completion of the combination
between Mizar and LSI, Mr. Forrest, Mr. Smith, and Mr. Rynearson were appointed
as members of the Compensation Committee. Messrs. Forrest, Rynearson and Irwin
were not at any time during the fiscal year ended June 30, 1998, officers or
employees of the Company. During fiscal 1998, no executive officer of the
Company served as a member of the board of directors or compensation committee
of any entity which has one or more executive officers serving as a member of
the Company's Board of Directors or Compensation Committee.

EMPLOYMENT AGREEMENTS

     Certain officers of the Company, including Mr. Yates, have entered into
employment contracts with the Company. These agreements define, among other
items, the terms of employment, remuneration, and notice periods for
termination.

     David Irwin, former President and CEO of the Company, who resigned in June
1997, had an employment agreement that provided for one year of compensation for
termination under certain circumstances.  The Company accrued approximately
$250,000 in the fiscal year ended 1997, related to Mr. Irwin's resignation from
the aforementioned positions.  Mr. Irwin served as a director of the Company
until his resignation from that position in February 1998.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders
of Loughborough Sound Images Limited

In our opinion, the consolidated balance sheet and the related consolidated
statements of operations, of changes in shareholders' deficit and of cash flows
present fairly, in all material respects, the financial position of Loughborough
Sound Images Limited and its subsidiaries at September 30, 1997 and the results
of their operations and their cash flows for each of the two years in the period
ended September 30, 1997, in conformity with accounting principles generally
accepted in the United States.  These financial statements (not presented
separately herein) are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits.  We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for the opinion expressed above.  We have not audited the consolidated financial
statements of Loughborough Sound Images Limited and its subsidiaries for any
period subsequent to September 30, 1997.
