Item 2.  Acquisition or Disposition of Assets.

        On April 27, 1998, the registrant, Blue Wave Systems Inc. (f/k/a Mizar,
Inc.), a Delaware corporation (the "Company"), completed an acquisition (the
"Acquisition") pursuant to which Loughborough Sound Images Limited, a company
registered in England and Wales ("LSI"), was acquired by the Company. In the
Acquisition, holders of LSI's ordinary shares and warrants and options
exercisable for ordinary shares of LSI received (or will receive upon conversion
or exercise of certain securities) a total of approximately 8,441,000 shares of
common stock, $.01 par value, of the Company (the "Common Stock"), which
represents approximately 60% of the outstanding shares of Common Stock, on a
fully diluted basis. The consideration for the purchase of the outstanding
capital of LSI was determined as a result of arms' length negotiation between
the Company and LSI, as more fully described in the Company's proxy statement
dated April 3, 1998. The Company's acquisition of LSI is being accounted for as
a pooling of interests.

        LSI designs, manufactures and markets a broad range of digital signal
processing products targeted at the embedded computing market. These products
are used by a wide variety of commercial and industrial customers in application
markets that include telecommunications, test and measurement, industrial
inspection and medical imaging. LSI has offices in the United Kingdom
(Loughborough, England), France (Paris), Germany (Munich) and in the United
States (Lexington, Massachusetts).

        None of the former LSI shareholders were affiliated with the Company as
of the time of the merger, although LSI was granted the right to designate three
nominees for director to the Board of Directors of the Company at the annual
meeting of the Company's stockholders held on April 27, 1998.

        Because the consideration for the ordinary shares and related options
tendered to the Company in the Acquisition consisted entirely of shares of
Common Stock and options of the Company exercisable for shares of Common Stock
("New Options"), the Company did not have any material funding requirements in
order to effect the Acquisition, except for the approximately $4 million paid to
redeem the outstanding preference shares of LSI at the closing of the 
Acquisition.

Item 5.  Other Events.

        In connection with the Acquisition, the Company amended its Certificate
of Incorporation to change its corporate name to "Blue Wave Systems Inc." The
combined operations of the Company and LSI will both operate under this new
name. In accordance with the share purchase agreement relating to the
Acquisition, Sam Smith resigned as interim Chief Executive Officer of the
Company and Simon Yates, the Managing Director of LSI, was elected as the
Company's President and Chief Executive Officer on April 27, 1998.

Item 7.  Financial Statements and Exhibits.

(a)  Financial statements of businesses acquired.

        (i)    Consolidated financial statements of LSI as of September 30, 1996
               and 1997, and for each of the three years in the period ended
               September 30, 1997, accompanied by the report of Price Waterhouse
               LLP thereon; and

        (ii)   Unaudited consolidated financial statements of LSI as of December
               31, 1997, and for the three months ended December 31, 1997.

(b)  Pro forma financial information. Unaudited pro forma combined financial
     statements of the Company and LSI as of December 31, 1997, and for each of
     the three years in the period ended June 30, 1997 (as to the Company) and
     September 30, 1997 (as to LSI), and for the six month periods ending
     December 31, 1996 and 1997.

(c)  Exhibits.

2.1     Share Purchase Agreement (the "Purchase Agreement") dated as of November
        17, 1997, between Mizar, Inc. and Loughborough Sound Images PLC.

2.2     Letter Agreement dated March 24, 1998 between Mizar, Inc. and
        Loughborough Sound Images Limited (f/k/a Loughborough Sound Images PLC),
        amending the Purchase Agreement.

Item 9.  Sales of Equity Securities Pursuant to Regulation S.

        In connection with the acquisition of the outstanding securities of LSI
on April 27, 1998, the Company issued 7,876,964 shares of Common Stock and New
Options exercisable for 564,001 shares of Common Stock to all of the former
holders of ordinary shares and securities exercisable for such shares. The
foregoing issuances were based upon the exchange ratio (the "Exchange Ratio") of
94.632 shares of Common Stock for each ordinary share of LSI transferred to the
Company (including shares issuable under options). In consideration for the
issuance of the approximately 8,441,000 shares of Common Stock (including shares
issuable under New Options), the Company received 100% of the outstanding
ordinary shares (including shares issuable under LSI's warrants, which were
converted immediately prior to the Acquisition) and options of LSI.

        The Company issued the shares of Common Stock and New Options under the
exemption provided by Regulation S of the Securities Act of 1933, as amended
("Regulation S"). In relying on the foregoing exemption, the Company considered,
among other matters, representations from the former shareholders of LSI that
such shareholders were not residents of the United States nor were they
otherwise a "United States person," as defined under applicable provisions of
Regulation 

                                       3
<PAGE>
 
S. The Company also imposed the relevant offering restrictions required by the
provisions of Regulation S and received the agreement of the persons receiving
Common Stock and New Options of the Company to refrain from transferring such
shares or options other than as permitted by Regulation S.

        The New Options that were issued by the Company to former holders of
LSI's options were issued in exchange for the LSI options that remained
outstanding on the date of closing of the Acquisition. The New Options have
substantially the same terms as the former LSI options, except that (i) the
holder of each New Option, upon its exercise in accordance with its terms, will
be entitled to receive that whole number of shares of Common Stock (rounded to
the nearest whole share) into which the number of ordinary shares of LSI subject
to such holder's LSI option would be exchanged for based upon the Exchange Ratio
and (ii) the exercise price per share of Common Stock under the New Options
shall be equal to the exercise price per share of the LSI ordinary shares
applicable to such LSI option immediately prior to the Acquisition, divided by
the Exchange Ratio, and converted into U.S. dollars. The New Options may be
exercised in full or in part at any time until January 31, 2003.

        There were no net proceeds to the Company resulting from the issuance of
the Common Stock and the New Options.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders
of Loughborough Sound Images Limited
 
  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of changes in shareholders' equity
(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, 1996 and 1997 and the results of their operations and their
cash flows for each of the three years in the period ended September 30, 1997,
in conformity with accounting principles generally accepted in the United
States. These financial statements 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.

and other income and expenses. Translation adjustments have been recorded as a
separate component of shareholders' equity.
 
  Principles of consolidation--The accompanying consolidated financial
statements include the accounts of LSI and its wholly-owned subsidiaries after
elimination of intercompany transactions and balances.
 
  Interim Financial Data--The interim financial data as of December 31, 1997
and for the three months ended December 31, 1996 and 1997 is unaudited;
however, in the opinion of management of the Company, the interim data
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair presentation of the results for the interim periods
presented.
 
  Restricted cash--In connection with the establishment of an employee stock
ownership plan ("ESOP"), the Company has guaranteed the debt of the ESOP. The
guarantee required the Company to place cash in escrow in an amount equal to
the debt. Such cash has been reflected as restricted cash in the accompanying
consolidated financial statements. See Notes 6 and 12.
 
  Inventories--Inventories are stated at the lower of cost (including direct
materials, labor and applied overhead) or market value using the first-in,
first-out method. The Company periodically reviews inventory items on hand to
determine that items are realizable and are included in current or future
products. The Company provides allowances, if necessary, to reduce inventory
to its realizable value.
 
  Property, plant and equipment--Property, plant and equipment, including
assets under capital lease, are carried at acquisition cost. Depreciation and
amortization are computed on the straight-line basis over the estimated
remaining useful lives of the assets (ranging from 5 to 25 years). Repair and
maintenance expenditures are charged to operations as incurred, and
expenditures for major renewals and betterments are capitalized. When units of
property are disposed, the cost and related accumulated depreciation are
removed from the accounts, and the resulting gains or losses are included in
operations.
 
  The Company applies Statement of Financial Accounting Standard No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of" to determine whether the carrying amount of long-lived
assets may not be recoverable. The Company has determined that no impairment
loss need be recognized for the period presented.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Income taxes--The Company uses the liability method of accounting for income
taxes. Deferred taxes are based on the estimated future tax effects of
differences between the financial statement and tax bases of assets and
liabilities.
 
  Revenue recognition--Sales, net of value added taxes, and related cost of
sales are recognized as products are shipped to customers.
 
  Research and development--Product development and engineering primarily
include research and development costs which are charged to expense as
incurred.
 
  Net income (loss) per share--Effective December 31, 1997, the Company
adopted Statement of Financial Accounting Standards No. 128, "Earnings per
Share" ("FAS 128"). This statement established a new methodology for
calculating earnings per share ("EPS"). All periods presented in the
accompanying consolidated financial statements have been restated to conform
with the requirements of FAS 128. See Note 9.
 
  Use of estimates--Financial statements prepared in conformity with generally
accepted accounting principles require management to make estimates and
assumptions about reported amounts of assets and liabilities, disclosure of
contingent assets and liabilities and reported amounts of revenues and
expenses. Management must also make estimates and judgments about future
results of operations related to specific elements of the business in
assessing recoverability of assets and recorded values of liabilities. Actual
results could differ from those estimates.
 
  Fair value of financial instruments--Management believes the recorded values
of financial instruments approximate their current fair values as such items
are current in nature and/or generally bear variable interest rates which
adjust yield to derive current market value.
 
  Stock-based compensation--Effective October 1, 1996, the Company adopted
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-
based Compensation" ("FAS 123"). This statement requires the fair value of
stock options and other stock-based compensation issued to employees to either
be included as compensation in the statement of operations, or the pro forma
effect on net income of such compensation expense to be disclosed in the notes
to the Company's consolidated statements. The Company has adopted FAS 123 on a
disclosure basis only and has opted to continue to apply the existing
accounting rules contained in Accounting Principles Board Opinion No. 25
"Accounting for Stock Issued to Employees" ("APB 25"). As such, implementation
of FAS 123 did not impact the Company's financial position or results of
operations.

7. CAPITAL STOCK
 
 General
 
  Effective April 10, 1997, the Company restated its Articles of Association
resulting in an authorized share structure as follows: (a) 7,500,000
preference shares with a par value of (Pounds) 0.75 per share; (b) 80,000
ordinary shares with a par value of (Pounds) 1 per share; and (c) 25,000 "B"
ordinary shares with a par value of (Pounds) 1 per share.
 
  The preference shares and accrued dividends thereon rank first in
liquidation priority over all other equity shares and accrue first preference
cumulative dividends of 6% per annum beginning on April 1, 1998, such
dividends being payable in cash biannually on March 31 and September 30. The
preference shares also accrue a second preference cumulative dividend of 8%
per annum until March 31, 1998, and 2% per annum thereafter, such dividends
being payable in cash (or in at the election of the preference shareholders,
one additional preference share for each (Pounds) 1 in dividends due) on March
31 and September 30. The preference shares are, to the extent possible,
mandatorily redeemable on the earlier of (a) the sale of the Company, (b) the
sale of businesses or assets comprising more than 50% of the net assets, sales
or profits of the Company, (c) a public offering of the Company's shares, or
(d) as follows:

In addition, the consent or sanction of the holders of "B" ordinary shares is

certain actions, including but not limited to (a) the authorization or
issuance of additional shares or rights to acquire additional shares, (b)
reacquire shares or make distributions to shareholders other than in
accordance with the terms of shares issued, (c) reduce any uncalled liability,
(d) sell, lease or otherwise dispose of the whole or substantially all of its
business undertakings or assets, or (e) acquire another company.
 
 Preference Shares
 
  On April 10, 1997, the Company entered into an agreement with Boston
Holdings Limited ("BHL"), a subsidiary of BancBoston Capital Limited, to sell
to BHL at a subscription price of (Pounds)5,500,001 ($8,914,000), 5,500,000
preference shares, one "B" ordinary share, and warrants to acquire an
additional 20,115 "B" ordinary shares. The warrants are exercisable in whole
or in part through March 31, 2012 at a price determined by a formula but will
be between (Pounds)165 to (Pounds)212 per share. If a controlling interest in
the Company has not been sold privately or through a public offering by March
31, 2000, the exercise price of the warrants will be reduced by 5% to 10% per
year. Under the terms of the Company's Articles of Association, any proceeds
resulting from the exercises of the warrants must be used to redeem the
preference shares.
 
  The Company valued the warrants at (Pounds)360,000 ($583,000) and reflected
such amount of the proceeds noted above as an increase to additional paid-in
capital. In addition, the Company incurred $1,032,000 in costs ($827,000 cash
and the issuance of 601 ordinary shares valued at $205,000) to issue the
preference shares. Such amount has been reflected as a reduction of the
preference shares. Both the value of the warrants and the issuance costs are
being amortized to retained earnings over the estimated life of the warrants
and preference shares. The preference shares, net of the unamortized value of
the warrants and the issuance costs, has been reflected in the accompanying
consolidated financial statements as mandatorily redeemable preference shares.
 
 Share Options
 
  The Company granted options to directors and employees in 1993 to acquire
ordinary shares at an exercise price of (Pounds)22 per share which was
determined by the board of directors to be the per share fair value of the
Company's ordinary shares. Such options expire ten years after the date of
grant and are exercisable at any time after the third anniversary of the date
of grant. The Company also granted options in 1996 and 1997 to acquire
ordinary shares at an exercise price of (Pounds)22 per share which was
determined by the board of directors to be the per share fair value of the
Company's ordinary shares. These options are exercisable upon the (1) sale of
the Company, (2) sale of a majority ownership of the Company or (3) an initial
public offering of the Company's ordinary shares.
 
  The Company applies APB 25 to account for its share options. Accordingly, no
compensation cost has been recognized for grants of share options. Had
compensation cost for the share option grants been determined based on their
fair value, net income and net income available to ordinary shareholders for
the year ended September 30, 1996, would have been $328,000, and net income
per share would have been $5.26. There were no grants of share options in
1995, and the grants in 1997 were not significant. The fair value of option
grants in 1996 was estimated on the date of grant using the Black-Scholes
option pricing model with the following assumptions:--% dividend yield,--%
expected volatility, 5.72% risk-free interest rate, and an expected life of
three years.

9. EARNINGS PER SHARE
 
  Earnings per share have been calculated in accordance with the provisions of
FAS 128. All prior years' earnings per share data have been restated to
reflect the provisions of FAS 128. The implementation of this standard has
resulted in the presentation of a basic EPS calculation in the consolidated
financial statements as well as a diluted EPS calculation. Basic EPS is
computed by dividing net income (loss) available to ordinary shareholders by
the weighted average number of ordinary shares outstanding during each period.
Diluted EPS is computed by dividing net income (loss) available to ordinary
shareholders by the weighted average number of ordinary and ordinary share
equivalents outstanding (if dilutive), using the treasury stock method, during
each period. Ordinary share equivalents include share options and warrants.
Following is a reconciliation of the basic and diluted per share computations
(dollars in thousands, except per share amounts):

12. EMPLOYEE BENEFITS
 
 Employee Savings Plan
 
  The Company has an employee savings plan which allows for contributions by
the employees and the Company. The Company pays all general and administrative
expenses of the plan. During the years ended September 30, 1995, 1996 and
1997, the Company made contributions of $450,000, $430,000 and $409,000,
respectively.
 
 Employee Stock Ownership Plan
 
  In April of 1997, the Company established an employee stock ownership plan
(the "ESOP") for the benefit of employees of the Company. The ESOP borrowed
(Pounds)500,000 ($810,000) from a commercial bank and used the proceeds to
purchase 2,358 shares of the Company's ordinary shares from a director of the
Company at (Pounds)212 per share which was estimated to be the fair value of
the Company's ordinary shares. The Company has guaranteed the debt of the ESOP
and has placed in escrow cash in an equal amount of the debt. The Company has
reflected the guaranteed ESOP debt and a corresponding amount of guaranteed
ESOP obligations as a reduction of shareholders' equity in its consolidated
balance sheet at September 30, 1997. None of the shares acquired had been
allocated to the participants of the ESOP. Interest payments in 1997 were
$35,000.

 Litigation
 
  The Company is party to certain legal proceedings incidental to its
business. Certain claims arising in the ordinary course of business have been
filed or are pending against the Company. The Company accrues for claims that
are both probable and for which expected loss can be reasonably estimated.
Management believes that the resolution of any such claims will not materially
affect the financial position or results of operations of the Company.

operations principally designed, manufactured and sold products for the
videoconferencing industry. These activities operated as a distinct business
segment the results of which have been separately disclosed as discontinued
operations in the accompanying consolidated statements of operations. The VMG
operations were fully abandoned by September 30, 1997. Sales of VMG were
$189,000, $1,462,000 and $277,000 for the years ended September 30, 1995, 1996
and 1997, respectively.
 
15. SUBSEQUENT EVENT--MERGER WITH MIZAR, INC.
 
  On November 17, 1997, the Company and Mizar, Inc. ("Mizar") executed a
definitive agreement and plan of merger. The merger is contingent upon, among
other matters, the approval of the shareholders of the Company. The merger, if
completed, will be effected by Mizar issuing its common shares for each
ordinary share of the Company in accordance with the exchange ratio set forth
in the agreement and plan of merger. In addition, the warrants for the "B"
ordinary shares discussed in Note 7 will be exercised and the proceeds used to
redeem a portion of the preference shares, and outstanding options to purchase
ordinary shares of the Company will be exchanged for options to purchase Mizar
common stock based on the exchange ratio discussed above. The agreement
contains provisions for the payment of expenses up to a maximum of $1.3
million by either party if certain conditions are met and the transaction is
not completed.

UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
 
  The following unaudited pro forma combined condensed financial statements
assume a business combination between Mizar and LSI accounted for on a pooling
of interests basis. The pro forma combined condensed financial statements are
based on the respective historical financial statements and the notes thereto,
which are incorporated by reference or included elsewhere herein. The pro
forma combined balance sheet combines Mizar's December 31, 1997 unaudited
balance sheet with LSI's December 31, 1997 unaudited balance sheet. The pro
forma combined condensed statements of operations combine Mizar's historical
statements of operations for each of the three years in the period ended June
30, 1997 with the corresponding LSI historical statements of operations for
each of the three years in the period ended September 30, 1997. The pro forma
combined condensed statements of operations also combine Mizar's historical
unaudited statements of operations for the six months ended December 31, 1997
and 1996 with the corresponding LSI historical unaudited statements of
operations for the six months ended December 31, 1997 and 1996. The amounts
included as LSI historical amounts have been reclassified to conform to
classifications used by Mizar.
 
  The pro forma information is presented for illustrative purposes only and is
not necessarily indicative of the operating results or financial position that
would have occurred if the business combination had been consummated at the
beginning of the periods presented, nor is the pro forma financial information
necessarily indicative of future operating results or financial position.
 
  These pro forma combined condensed financial statements and the related
notes should be read in conjunction with the historical financial statements
and the related notes thereto of Mizar and LSI included elsewhere herein. See
"Index to Financial Statements."

               NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
 
  The unaudited pro forma combined financial statements give effect to the
business combination between Mizar, Inc. and Loughborough Sound Images, Ltd.
accounted for on a pooling-of-interests basis. The pro forma combined
financial statements are based on the respective historical financial
statements and the notes thereto. The pro forma combined balance sheet
combines Mizar's and LSI's balance sheet as of December 31, 1997. The pro
forma combined statements of operations combine Mizar's and LSI's historical
statements of operations for each of the three years in the period ended June
30, 1997, and September 30, 1997, respectively, and the unaudited statements
of operations for the six months ended December 31, 1997 and December 31,
1996. LSI's historical statements of operations for the years ended September
30, 1997 and 1996 include the same unaudited statement of operations
information for the quarter ended September 30, 1997 and 1996, which is
included in the six months ended December 31, 1997 and 1996.
 
  The pro forma information is presented for illustrative purposes only and is
not necessarily indicative of the operating results or financial position that
would have occurred if the business combination had been consummated at the
beginning of the periods presented nor is it necessarily indicative of future
operating results or financial position.
 
  These pro forma combined financial statements should be read in conjunction
with the historical financial statements and the related notes thereto of
Mizar and LSI included or incorporated elsewhere herein. See "Index to
Financial Statements."
 
  Adjustments to the pro forma combined statements of operations assume the
merger of Mizar and LSI was consummated on July 1, 1994. The adjustments to
the pro forma balance sheet assume the business combination was consummated on
December 31, 1997. The business combination has been accounted for using the
pooling-of-interests method of accounting. The following adjustments have been
provided in connection with the business combination in accordance with
Accounting Principles Board Opinion No. 16:
 
1) Reflecting the redemption of Preferred Shares held by Bank Holdings and the
   elimination of related interest expense. The amount of the redemption is
   $9,441,000 and is reflected as a reduction in marketable securities and as
   a reduction in the number of outstanding Preference Shares, retained
   earnings, and accrued liabilities.
 
2) The exercise of warrants for ordinary shares in LSI held by Bank Holdings.
   This adjustment is reflected as a $19,000 increase in common stock, a
   $5,360,000 increase in paid-in-capital and a $5,379,000 increase in
   marketable securities. The issuance of shares of Mizar Common Stock in
   exchange for the outstanding shares of LSI is reflected as a $59,000
   increase to common stock and a decrease in paid-in-capital.
 
                                      29
<PAGE>
 
3) The accrual of expenses related to the business combination of $2,500,000.
   This accrual is reflected as an increase in accounts payable and a reduction
   in retained earnings. This charge will be reflected as an expense in the
   first accounting period immediately following the consummation of the
   business combination.
 
4) Retained earnings has been decreased and paid in capital has been increased
   for a $3,500,000 compensation expense entry related to certain variable
   options of LSI. This non-cash charge will be reflected as an expense in the
   first accounting period immediately following the consummation of the
   combination.

LSI shall use its reasonable best efforts (a) to cause each of the registered
shareholders of LSI (collectively, the "LSI Shareholders") to accept an offer
made by Mizar to the LSI Shareholders by entering into a share exchange
agreement, in a mutually agreeable form, between such shareholder and Mizar (the
"Share Exchange Agreements"), which shall provide for each LSI Shareholder to
sell, assign, transfer, convey and deliver to Mizar, and for Mizar to purchase,
all right, title and interest in and to all of such shareholder's shares of LSI
Stock (as defined in Section 3.7 below), free and clear of all liens, security
interests, charges, encumbrances and rights of others and (b) to cause each
person holding Old Options (as defined in Section 2.4 below) (such persons shall
be collectively referred to herein as the "LSI Optionholders") to enter into an
option exchange agreement, in a mutually agreeable form, between such LSI
Optionholder and Mizar (the "Option Exchange Agreements"), which shall provide
for each LSI Optionholder either to exercise his Old Options for shares of LSI
Stock, which shall then be sold to Mizar, or to enter into a new option
agreement with Mizar as set forth in Section 2.4 below, at the option of such
LSI Optionholder. In addition, LSI shall use its reasonable best efforts to
cause Boston Holdings Limited ("Bank") to enter into an agreement, in a mutually
agreeable form, with LSI and Mizar (the "Bank Agreement," and together with the
Share Exchange Agreement and the Option Exchange Agreement, the "Exchange
Agreements"), which shall provide for (a) Bank to exercise all the Warrants (as
defined in Section 2.4 below) for shares of LSI Stock which shall then be
exchanged for shares of Mizar Common Stock, (b) LSI to use all of the proceeds
of such exercise to redeem Preferred Shares (as defined in Section 3.7 below),
and (c) Bank to sell any Preferred Shares not so redeemed (the "Remaining
Preferred Shares") to Mizar for an amount per share that is equal to the amount
payable upon redemption of the Remaining Preferred Shares. The Exchange
Agreements shall be mailed by 
<PAGE>
 
Mizar to the other parties to such agreements with such covering letters or
other documentation as may be necessary or desirable to comply with any relevant
provisions of United States and United Kingdom law. No such mailing shall be
made unless and until the parties shall have agreed on the form of all documents
referred to in this agreement as being "in a mutually agreeable form," and until
LSI shall have re-registered as a private company under section 53 Companies Act
1985 (the "Companies Act") and shall have received a certificate of change of
name from the Registrar of Companies confirming such re-registration. In
consideration for the shares of LSI Stock so acquired by Mizar, Mizar shall
issue and deliver 94.632 shares of common stock, $.01 par value, of Mizar
("Mizar Common Stock") in exchange for each share of LSI Stock transferred to
Mizar pursuant to an Exchange Agreement, as soon as practicable following the
satisfaction or permissible waiver of the conditions set forth in Articles 6 and
7 (the exchange of shares of Mizar Common Stock for shares of LSI Stock,
including shares issued at the Closing (as defined in Section 1.2 below) upon
the exercise of the Options and Warrants, shall be referred to herein as the
"Exchange").

        1.2. Closing. Consummation of the transactions contemplated by this
             -------
Agreement and the Exchange Agreements (the "Closing"), shall take place at the
executive offices of Mizar in Carrollton, Texas, commencing at 10:00 a.m., local
time, as soon as practicable after the last to be fulfilled or waived of the
conditions set forth in Articles 6 and 7, or at such other place, time and date
as shall be fixed by mutual agreement between Mizar and LSI. The day on which
the Closing shall occur shall be referred to herein as the "Closing Date." Each
party will use its reasonable best efforts to cause to be prepared, executed and
delivered the documents to be delivered pursuant to Articles 6 and 7 and all
other appropriate and customary documents as any party or its counsel may
reasonably request for the purpose of consummating the transactions contemplated
by this Agreement or the Exchange Agreements. LSI will use its reasonable best
efforts to facilitate the consummation of the transactions contemplated by the
Exchange Agreements at or prior to the Closing. All actions taken at the Closing
shall be deemed to have been taken simultaneously at the time the last of any
such actions is taken or completed.

        1.3. Tax Consequences. It is the intention of the parties hereto that no
             ----------------  
taxable income or gain shall be recognized by holders of LSI Stock upon the
Exchange under Section 135 of the TCGA.

        1.4. Pooling of Interests. It is the intention of the parties hereto
             --------------------
that the Exchange will be treated for financial reporting purposes in the United
States as a pooling of interests.

                                  ARTICLE 2.
             EXCHANGE OF SHARES; TREATMENT OF OPTIONS AND WARRANTS

        2.1. Warrants; Options; Exchange of Shares. On or before the Closing
             -------------------------------------
Date, as provided in the applicable Exchange Agreements, but subject to the
Closing, the Warrants shall be exercised, in accordance with their terms, into
shares of LSI Stock, and each outstanding Old Option shall be, at the option of
the holder, exercised or converted into an option for shares of 


                                       2
<PAGE>
 
Mizar Common Stock, as described in Section 2.4. Immediately after the
satisfaction or permissible waiver of the conditions set forth in Articles 6 and
7 at the Closing, and after giving effect to the foregoing, each of the shares
of LSI Stock that are outstanding and tendered to Mizar pursuant to the Exchange
Agreements (the "Converted Shares") shall be exchanged for 94.632 (such number
being referred to herein as the "Exchange Ratio") shares of Mizar Common Stock.

        2.2. Fractional Shares. No scrip or fractional shares of Mizar Common
             -----------------
Stock shall be issued in the Exchange. All fractional shares of Mizar Common
Stock to which an LSI Shareholder would otherwise be entitled at the Closing
Date pursuant to a Share Exchange Agreement shall be aggregated. If a fractional
share results from such aggregation, then such shareholder shall be entitled,
after the later of (a) the Closing Date or (b) the surrender of such
shareholder's Certificate (as defined in Section 2.5 below) or Certificates that
represent such shares, to receive from Mizar an amount in cash in lieu of such
fractional share. The amount of such cash payment shall be equal to such
fractional proportion of the Average Closing Price (as defined below) of a share
of the Mizar Common Stock. For purposes of this Agreement, "Average Closing
Price" shall mean the average per share closing price for the Mizar Common Stock
as reported on the Nasdaq National Market System (the "NMS") over the twenty
(20) trading days ending on the fifth full trading day prior to the Closing
Date. Mizar will make available to the Exchange Agent (as defined in Section 2.5
below) the cash necessary for the purpose of paying cash for fractional shares.

        2.3. Demand Rights. LSI shall use its reasonable best efforts to
             -------------
provide that LSI Shareholders who have not, immediately prior to the Closing
Date, tendered their shares of LSI Stock and accepted the Exchange, and with
respect of which Mizar has validly exercised its rights properly demanded in
accordance with the applicable provisions of Section 429, the Companies Act,
comply with the provisions of Part XIIIA of the Companies Act, and both LSI and
Mizar agree that they shall comply with the provisions of Part XIIIA of the
Companies Act.

        2.4. Stock Options.
             -------------  

             (a) On the Closing Date, LSI shall use its reasonable best
        efforts to provide that all share options (the "Old Options") then
        outstanding under LSI's share option plans (the "Option Plans"), shall,
        pursuant to the Option Exchange Agreements, be exercised for shares of
        LSI Stock (immediately prior to the Exchange), or exchanged in
        accordance with the Option Exchange Agreements for options for Mizar
        Common Stock ("New Options"), to the effect that (i) the holder of each
        such New Option, upon its exercise in accordance with its terms, shall
        be entitled to receive that whole number of shares of Mizar Common Stock
        (rounded to the nearest whole share) into which the number of shares of
        LSI Stock subject to the Old Option exchanged for such New Option would
        be converted based upon the Exchange Ratio, (ii) the exercise price per
        share of Mizar Common Stock under the New Options shall be equal to the
        exercise price per share of LSI Stock applicable to such Old Option
        immediately prior to the Exchange, divided by the Exchange Ratio, and
        converted into U.S. dollars using the average currency conversion rate
        for converting 


                                       3
<PAGE>
 
        British Pounds into U.S. dollars over the ten (10) days ending on the
        second day before the Closing Date (and rounded to the nearest cent),
        and (iii) all other terms and conditions of the New Options shall be
        substantially the same as under the Old Options, as more explicitly set
        forth in the Option Exchange Agreements. The terms of the New Options
        shall acknowledge the fact that a triggering event shall have occurred
        under the Old Options as a result of the Exchange. From and after the
        date of this Agreement, no additional options shall be granted by LSI
        under the Option Plans or otherwise.

               (b) It is intended that the New Options, as set forth herein,
        shall not give to any holder thereof any benefits in addition to those
        which such holder had prior to the conversion of the Old Options into
        New Options. Mizar shall take all corporate action necessary to reserve
        for issuance a sufficient number of shares of Mizar Common Stock for
        delivery upon exercise of the New Options. As soon as practicable after
        the Closing Date, Mizar shall file a registration statement, or an
        amendment to an existing registration statement, under the Securities
        Act of 1933, as amended (the "Securities Act"), on Form S-8 (or other
        successor form) with respect to the unissued shares of Mizar Common
        Stock subject to any unexercised New Options and shall use its best
        efforts to maintain the effectiveness of such registration statement for
        so long as such New Options remain outstanding. In addition, Mizar will
        cause the shares of Mizar Common Stock issuable under the New Options to
        be listed on the NMS.

               (c) Approval by the stockholders of Mizar of this Agreement shall
        constitute authorization and approval of any and all of the actions
        described in this Section 2.4.

        2.5.   Exchange Agent.
               --------------

               (a) Mizar shall authorize Securities Transfer Corp., or such
        other firm as is reasonably acceptable to LSI, to serve as exchange
        agent hereunder (the "Exchange Agent"). Promptly after the Closing Date,
        Mizar shall deposit or shall cause to be deposited in trust with the
        Exchange Agent (i) certificates representing the number of whole shares
        of Mizar Common Stock to which the holders of LSI Stock are entitled
        pursuant to the Exchange Agreements and Section 2.1(a), and (ii) cash
        sufficient to pay for fractional shares then known to Mizar, if
        applicable (such cash amounts and certificates being hereinafter
        referred to as the "Exchange Fund"). The Exchange Agent shall, pursuant
        to irrevocable instructions received from Mizar, deliver the number of
        shares of Mizar Common Stock and pay the amounts of cash required under
        this Article 2 with respect to each Converted Share out of the Exchange
        Fund. Any cash needed from time to time by the Exchange Agent to make
        payments for fractional shares shall be provided by Mizar and shall
        become part of the Exchange Fund. The Exchange Fund shall not be used
        for any other purpose, except as provided in this Agreement, or as
        otherwise agreed to by Mizar and LSI prior to the Closing Date.

                                       4
<PAGE>
 
               (b) As soon as practicable after the Closing Date, the Exchange
        Agent shall mail and otherwise make available to each LSI Shareholder
        who, as of the Closing Date, was a record holder of an outstanding
        certificate or certificates, which immediately prior to the Closing Date
        represented shares of LSI Stock (the "Certificates"), a stock transfer
        form or other appropriate documents of transfer and instructions for
        their use in effecting the surrender of the Certificates for payment
        therefor and exchange thereof, which transfer documents shall comply
        with all applicable rules of the NMS.

               (c) Delivery of Certificates shall be effected, and risk of loss
        and title to the Certificates shall pass, only upon proper delivery of
        the Certificates to the Exchange Agent, and the form of transfer
        documents shall so reflect. Upon surrender to the Exchange Agent of a
        Certificate, together with such transfer documents duly executed, the
        holder of such Certificate shall be entitled to receive in exchange
        therefor one or more certificates as requested by the holder (properly
        issued, executed and countersigned, as appropriate) representing that
        number of whole shares of Mizar Common Stock to which such holder of LSI
        Stock shall have become entitled pursuant to the provisions of this
        Article 2, and the Certificate so surrendered shall forthwith be
        canceled.

               (d) Mizar shall pay any stamp duty transfer taxes or other
        transfer taxes under the laws of the United Kingdom and the United
        States required by reason of the transfer to Mizar of LSI Stock or the
        issuance of a certificate representing shares of Mizar Common Stock if
        such certificate is issued in the name of the person in whose name the
        Certificate surrendered in exchange therefor is registered. If any
        portion of the consideration to be received pursuant to this Article 2
        upon exchange of a Certificate is to be issued or paid to a person other
        than the person in whose name the Certificate surrendered in exchange
        therefor is registered, it shall be a condition of such issuance and
        payment that the Certificate so surrendered shall be properly endorsed
        or otherwise in proper form for transfer and that the person requesting
        such exchange shall pay in advance any stamp duty transfer or other
        taxes required by reason of the issuance of a certificate representing
        shares of Mizar Common Stock to such other person, or establish to the
        satisfaction of the Exchange Agent that such tax has been paid or that
        no such tax is applicable. From the Closing Date until surrender in
        accordance with the provisions of this Section 2.5, each Certificate
        shall represent for all purposes only the right to receive the
        consideration provided in Sections 2.1 and 2.2. No dividends that are
        otherwise payable on Mizar Common Stock will be paid to persons entitled
        to receive Mizar Common Stock until such persons surrender their
        Certificates. After such surrender, there shall be paid to the person in
        whose name Mizar Common Stock shall be issued any dividends on such
        Mizar Common Stock that have a record date on or after the Closing Date
        and prior to such surrender. In no event shall the persons entitled to
        receive such dividends, if any, be entitled to receive interest on such
        dividends.

               (e) In the case of any lost, mislaid, stolen or destroyed
        Certificates, the holder thereof may be required, as a condition
        precedent to the delivery to such holder of the 

                                       5
<PAGE>
 
        consideration described in this Article 2, to deliver to Mizar a bond in
        such reasonable sum as Mizar may direct as indemnity against any claim
        that may be made against the Exchange Agent, Mizar or LSI with respect
        to the Certificate alleged to have been lost, mislaid, stolen or
        destroyed.

               (f) After the Closing Date, there shall be no transfers on the
        share register of LSI of the shares of LSI Stock that were outstanding
        immediately prior to the Closing Date.

        2.6.   Adjustments. If, between the date of this Agreement and the
               -----------
Closing Date, (i) the outstanding shares of LSI Stock or Mizar Common Stock
shall have been changed into a different number of shares or a different class
by reason of any reclassification, recapitalization, split-up, combination,
exchange of shares, or readjustment or a stock dividend thereon shall be
declared with a record date within such period, or (ii) Mizar or LSI shall have
issued additional shares of its capital stock (except upon conversion or
exercise of outstanding convertible securities or options or warrants), or
options or warrants to purchase capital stock, or securities convertible into
capital stock (except for issuances of options by Mizar or LSI that are
consented to by the Managing Director of LSI and the chief executive officer of
Mizar and issuances of any New Options), then the consideration to be received
pursuant to Section 2.1(a) hereof by the holders of shares of LSI Stock shall be
adjusted to accurately reflect such change.

                                   ARTICLE 3.
                      REPRESENTATIONS AND WARRANTIES OF LSI

        fully paid, nonassessable and free of preemptive rights.

               (c) To LSI's knowledge, there are no voting trusts, shareholder

        3.8.   Financial Statements and Records of LSI. LSI has made available
               ---------------------------------------
to Mizar true, correct and complete copies of the following financial statements
(the "LSI Financial Statements"):

               (a) the audited consolidated balance sheet and profit and loss
        account of LSI and its subsidiaries as of September 30, 1995 and 1996
        and for the years then ended, including the notes thereto, in both cases
        examined by and accompanied by the report of Price Waterhouse, LP
        (collectively, the "LSI Year-End Statements"); and

               (b) the unaudited consolidated management account and balance
        sheet of LSI and its subsidiaries as of September 30, 1997, with any

<PAGE>
 
The LSI Financial Statements present fairly, in all material respects, the
financial position of LSI and/or its subsidiaries, as the case may be, as of the
dates thereof and the results of operations and cash flows thereof for the
periods then ended, in each case in conformity with the legal requirements and
generally accepted accounting principles relevant to such entity's place of
incorporation, consistently applied, except as noted therein. Since September
30, 1996, there has been no change in accounting principles applicable to, or
methods of accounting utilized by, LSI and/or such LSI Subsidiary, as the case
may be, except as noted in the LSI Financial Statements. The books and records
of LSI have been and are being maintained in accordance with good business
practice, reflect only valid transactions and are complete and correct in all
material respects.

        3.9.   Absence of Certain Changes. Since September 30, 1997, LSI and the
               --------------------------
LSI Subsidiaries have not, except as otherwise set forth on the LSI Disclosure
Schedule:

        3.11.  Tax Returns; Taxes. Each of LSI and the LSI Subsidiaries (a) have
               ------------------
duly filed all material local and foreign tax returns and reports required to be
filed by it, including those with respect to advance corporation tax, capital
gains tax, corporation tax, excise duties, income tax (including "Pay as You
Earn"), inheritance tax, insurance premium tax, National Insurance

deficiency, delinquency or default for any tax, assessment or governmental
charge has been claimed, proposed or assessed against LSI or the LSI
Subsidiaries, nor has LSI or the LSI Subsidiaries received notice of any such

Subsidiaries have no material tax liabilities other than those reflected on LSI
Balance Sheet and those arising in the ordinary course of business since the
date thereof. LSI will make available to Mizar true, complete and correct copies
of LSI's tax returns for the last five years and make available such other tax
returns requested by Mizar. The income tax liabilities of LSI and the LSI

        3.12. Material Contracts. LSI has furnished or made available to Mizar
              ------------------
accurate and complete copies of the LSI Material Contracts applicable to LSI or
the LSI Subsidiaries. Except as set forth on the LSI Disclosure Schedule, there
is not under any of the LSI Material Contracts any existing breach, default or
event of default by LSI or any LSI Subsidiary nor event that with notice or
lapse of time or both would constitute a breach, default or event of default by
LSI or the LSI Subsidiaries, other than breaches, defaults or events of default
which would not have an LSI Material Adverse Effect nor does LSI know of, and
LSI has not received notice of, or made a claim with respect to, any breach or
default by any other party thereto which would, severally or in the aggregate,
have an LSI Material Adverse Effect. As used herein, the term "LSI Material
Contracts" shall mean all (i) employee benefit plans, share option schemes or
agreements and employment, consulting or similar contracts, (ii) contracts that
involve remaining aggregate payments by LSI or an LSI Subsidiary in excess of
$100,000 (or equivalent based on applicable exchange rate) or which have a
remaining term in excess of one year and (iii) insurance policies.

        3.13. Litigation and Government Claims. There is no pending suit,
              --------------------------------
claim, action or litigation, or administrative, arbitration or other proceeding
or governmental investigation or inquiry against LSI or the LSI Subsidiaries to
which their businesses or assets are subject which would, severally or in the
aggregate, reasonably be expected to result in an LSI Material Adverse Effect.

contemplated which would, severally or in the aggregate, have an LSI Material
Adverse Effect. Neither LSI nor the LSI Subsidiaries is subject to any judgment,
decree, injunction, rule or order of any court, or, to the knowledge of LSI, any
governmental restriction applicable to LSI or the LSI Subsidiaries which is
reasonably likely (i) to have an LSI Material Adverse Effect or (ii) to cause a
material limitation on Mizar's ability to own and operate the business of LSI
(as it is currently operated) after the Closing.

        3.14. Compliance With Laws. LSI and the LSI Subsidiaries each have all 
              --------------------
material authorizations, approvals, licenses and orders to carry on their
respective businesses as they are now being conducted, to own or hold under
lease the properties and assets they own or hold under lease and to perform all
of their obligations under the agreements to which they are a party, except for
instances which would not have an LSI Material Adverse Effect. LSI and the LSI
Subsidiaries have been and are, to the knowledge of LSI, in compliance with all
applicable laws, regulations and administrative orders of any country, state or
municipality or of any subdivision of any thereof to which their respective
businesses, ownership of assets and their employment of labor or their use or
occupancy of properties or any part thereof are subject, the violation of which
would have an LSI Material Adverse Effect.

        party, including without limitation (i) all severance, employment,
        consulting or similar contracts, (ii) all material agreements and
        contracts with "change of control" provisions or similar provisions and
        (iii) all indemnification agreements or arrangements with directors or
        officers.

        material respects with all laws respecting employment and employment
        practices, terms and conditions of employment, wages and hours, and is
        not engaged in any unfair labor or unlawful employment practice. There
        is no unlawful employment practice discrimination charge pending before
        any competent court or tribunal. Except as would not have an LSI
        Material Adverse Effect, there is no unfair labor practice charge or
        complaint against LSI or the LSI Subsidiaries pending before any
        competent court or tribunal. There is no labor strike, dispute, slowdown
        or stoppage actually pending or, to the knowledge of LSI, threatened
        against or involving or affecting LSI or the LSI Subsidiaries and no
        representation question exists with respect to their respective
        employees. Except as would not have an LSI Material Adverse Effect, no
        grievances or arbitration proceeding is pending and no written claim
        therefor exists. There is no collective bargaining agreement or trade
        union recognition agreement that is binding on LSI or the LSI
        Subsidiaries.

        3.17.  Intellectual Property. LSI and the LSI Subsidiaries own or have
               ---------------------

trade names, service marks, service names, copyrights, applications therefor and
licenses or other rights in respect thereof ("LSI Intellectual Property") used
or held for use in connection with the business of LSI or the LSI Subsidiaries,
without any known conflict with the rights of others, except for such conflicts
as do not have an LSI Material Adverse Effect. Neither LSI nor any of the LSI
Subsidiaries have received any notice from any other person pertaining to or
challenging the right of LSI or the LSI Subsidiaries to use any LSI Intellectual
Property or any trade secrets, proprietary information, inventions, know-how,
processes and procedures owned or used or licensed to LSI or the LSI
Subsidiaries, except with respect to rights the loss of which, individually or
in the aggregate, would not have an LSI Material Adverse Effect. The LSI
Intellectual Property represents all of the proprietary rights necessary to
operate the respective businesses of LSI and the LSI Subsidiaries.

        of business), and all of such properties and all assets purchased by LSI
        since the date of the LSI Balance Sheet are free and clear of any lien,

                   (ii)  statutory liens incurred in the ordinary course of
               business that are not yet due and payable or the validity of

                   (iv)  other liens, claims or encumbrances that, in the
               aggregate, do not materially subtract from the value of, or
               materially interfere with, the present use of, the LSI Real
               Estate.

        Except for those assets acquired since the date of the LSI Balance
        Sheet, all properties and assets material to the present operations of

        hazardous wastes or substances

the SEC required to be filed by it pursuant to the federal securities laws and
the SEC rules and regulations thereunder, each of which complied as to form, at

               (a) the balance sheets of Mizar as of June 30, 1997 and June 30,
        1996, and the related statements of income, stockholders' equity and

utilized by, Mizar, except as noted in Mizar Financial Statements. The books and
records of Mizar have been and are being maintained in accordance with good
business practice, reflect only valid transactions, are complete and correct in
all material respects, and present fairly in all material respects the basis for
the financial position and results of operations of Mizar set forth in Mizar

        charge or complaint against Mizar pending before the National Labor

        such properties and all assets purchased by Mizar since the date of the
        Mizar Balance Sheet are free and clear of any lien, claim or

               proceedings;

                      (iii)  landlord liens contained in leases entered in the
               ordinary course of business; and

<PAGE>
 
                      (iv)   other liens, claims or encumbrances that, in the
               aggregate, do not materially subtract from the value of, or
               materially interfere with, the present use of, the Mizar Real
               Estate.

        Except for those assets acquired since the date of the Mizar Balance
        Sheet, all properties and assets material to the present operations of
        Mizar are owned or leased by Mizar and are reflected on the Mizar

        by generally accepted accounting principles.

        been received by Mizar. No such condemnation, requisition or taking is
        threatened or contemplated to Mizar's actual knowledge, and there are no
        pending public improvements which may result in special assessments
        against or which may otherwise materially and adversely affect the Mizar
        Real Estate. To the actual knowledge of Mizar, the Mizar Real Estate has
        not been used for deposit or disposal of hazardous wastes or substances
        in violation of any past or current law in any material respect and

        to emissions, discharges and releases of hazardous or toxic materials
        into the environment, except as would not cause a Mizar Material Adverse
        Effect. To Mizar's actual knowledge, no hazardous or toxic material (as
        defined in Section 3.18) exists in any structure located on, or exists

        such returns, reports, filings and amendments at Mizar's offices prior
        to the filing thereof, which review shall not interfere with the timely
        filing of such returns.

        In connection with the continued operation of the business of Mizar
between the date of this Agreement and the Closing Date, Mizar shall confer in

LSI Material Adverse Effect or a Mizar Material Adverse Effect.

        5.4. Inspection and Access to Information.
             ------------------------------------

        information which is generally available to the public) concerning the
        other parties hereto acquired pursuant to the transactions contemplated
        hereby in the event that the Exchange is not consummated. Each of the

        so obtained for any purpose other than in connection with the Exchange.
        All files, records, documents, information, data and similar items
        relating to the confidential information of LSI, whether prepared by

        exclusive property of LSI and shall be promptly delivered to LSI upon
        termination of this Agreement. All files, records, documents,

        meeting of the stockholders of Mizar in connection with the Exchange

        registration statement, in the form it is declared effective by the SEC,
        together with any and all amendments and supplements thereto and all
        information incorporated by reference therein, is referred to herein as
        the "Registration Statement") under and pursuant to the provisions of
        the Securities Act for the purpose of registering Mizar Common Stock to
        be issued in the Exchange. Mizar will use its best efforts to receive
        and respond to the comments of the SEC and to have the Registration
        Statement declared effective as promptly as practicable, and Mizar shall
        promptly mail to its stockholders the Proxy Statement in its definitive
        form contained in the Registration Statement.

             (b) Each of Mizar and LSI agrees to provide as promptly as
        practicable to the other such information concerning its business and
        financial statements and affairs as, in the reasonable judgment of the

        Registration Statement and the Proxy Statement or in any amendments or
        supplements thereto, and to cause its counsel and auditors to cooperate
        with the other's counsel and auditors in the preparation of the
        Registration Statement and the Proxy Statement.

             (c) Each of the parties shall use their best efforts to ensure
        that at the time the Registration Statement becomes effective, as such
        Registration Statement is then amended 


                                      29
<PAGE>
 
        or supplemented, at the time the Proxy Statement is mailed to Mizar's
        stockholders and at the Closing Date, such Registration Statement and
        Proxy Statement (i) will not, with respect to such party, contain any
        untrue statement of a material fact, or omit to state any material fact
        required to be stated therein as necessary, in order to make the
        statements made by such party therein, in light of the circumstances
        under which they were made, not misleading or necessary and (ii) will
        comply in all material respects with the provisions of the Securities
        Act and Exchange Act, as applicable, and the rules and regulations
        thereunder; provided, however, no representation is made by Mizar or LSI
        with respect to statements made in the Registration Statement and Proxy
        Statement based on information supplied by the other party expressly for
        inclusion or incorporation by reference in the Proxy Statement or

        5.6. Affiliates. At least 30 days prior to the Closing Date, LSI shall
             ----------
deliver to Mizar a letter identifying all persons who are, as of the date
thereof, "affiliates" of LSI for purposes of Rule 145 under the Securities Act,
and shall provide an updated letter identifying any such persons on the Closing
Date. LSI shall use its reasonable efforts to cause each person who is
identified as an "affiliate" in the letter dated the Closing Date to deliver to
Mizar on or prior to the Closing Date a written statement, in form satisfactory
to Mizar and LSI, that such person will not offer to sell, transfer or otherwise
dispose of any of the shares of Mizar Common Stock issued to such person
pursuant to the Exchange, (i) except in accordance with the applicable
provisions of the Securities Act and the rules and regulations thereunder and
(ii) until such time as financial results covering at least 30 days of combined
operations of Mizar and LSI (the "Combined Financials") have been published.
Mizar hereby covenants to file a Form 8-K or 10-Q (as applicable) satisfying
such publication requirement as soon as practicable after the completion of any
month which contains at least 30 days of combined operations. Furthermore, Mizar
shall use its reasonable best efforts to cause each person who is an "affiliate"
of Mizar to deliver a letter to Mizar agreeing that such person will not offer
to sell, transfer or otherwise dispose of any shares of Mizar Common Stock
commencing 30 days prior to the Exchange until such time as the Combined
Financials have been published. Mizar shall be entitled to place legends on any
certificates of Mizar Common Stock issued to such affiliates to restrict the
transfer of such shares as set forth above.

        5.7. Stockholders' Meeting. Mizar will take all action necessary in
             ---------------------
accordance with applicable law and its governing corporate documents to convene
a meeting of its stockholders as promptly as practicable to consider and vote

             -------------------
Date, Mizar will file a listing application with the NMS to approve for listing,
subject to official notice of issuance, the shares of Mizar Common Stock to be
issued in the Exchange. Mizar shall use its reasonable 


                                      30
<PAGE>
 
efforts to cause the shares of Mizar Common Stock to be issued in the Exchange
to be approved for listing on the NMS, subject to official notice of issuance,
prior to the Closing Date.

        5.9. Reasonable Efforts; Further Assurances; Co-operation. Subject to
             ----------------------------------------------------
the other provisions of this Agreement, the parties hereto shall each use their
reasonable efforts to perform their obligations herein and to take, or cause to
be taken or do, or cause to be done, all things reasonably necessary, proper or
advisable under applicable law to obtain all regulatory approvals and satisfy
all conditions to the obligations of the parties under this Agreement and to
cause the Exchange and the other transactions contemplated herein to be carried
out promptly in accordance with the terms hereof and shall cooperate fully with
each other and their respective officers, directors, employees, agents, counsel,
accountants and other designees in connection with any steps required to be
taken as a part of their respective obligations under this Agreement, including
without limitation:

             (a) LSI and Mizar shall promptly make their respective filings
        and submissions and shall take, or cause to be taken, all actions and
        do, or cause to be done, all things reasonably necessary, proper or
        advisable under applicable laws and regulations to (i) comply with the
        provisions of the Securities Act, Exchange Act and the Takeover Code,
        and (ii) obtain any other required approval of any other federal, state
        or local governmental agency or regulatory body with jurisdiction over
        the transactions contemplated by this Agreement.

             (b) In the event any claim, action, suit, investigation or other
        proceeding by any governmental body or other person is commenced which
        questions the validity or legality of the Exchange or any of the other
        transactions contemplated hereby or seeks damages in connection
        therewith, the parties agree to cooperate and use all reasonable efforts
        to defend against such claim, action, suit, investigation or other
        proceeding and, if an injunction or other order is issued in any such
        action, suit or other proceeding, to use all reasonable efforts to have
        such injunction or other order lifted, and to cooperate reasonably
        regarding any other impediment to the consummation of the transactions
        contemplated by this Agreement.

             (c) Each party shall give prompt written notice to the other of
        (i) the occurrence, or failure to occur, of any event which occurrence
        or failure would be likely to cause any representation or warranty of
        LSI or Mizar, as the case may be, contained in this Agreement to be
        untrue or inaccurate in any material respect at any time from the date
        hereof to the Closing Date or that will or may result in the failure to
        satisfy the Conditions specified in Article 6 or 7 and (ii) any failure
        of LSI or Mizar, as the case may be, to comply with or satisfy any
        covenant, condition or agreement to be complied with or satisfied by it
        hereunder.

             (d) Mizar and LSI shall take all actions that the parties deem
        necessary or advisable for purposes of obtaining duly executed Exchange
        Agreements from each of the 


                                      31
<PAGE>
 
        LSI Shareholders, LSI Optionholders and Bank, and to cause the
        consummation of the transactions contemplated thereby at the Closing.

        5.10.    Public Announcements. The timing and content of all
                 --------------------
announcements regarding any aspect of this Agreement or the Exchange to the
financial community, government agencies, employees or the general public shall
be mutually agreed upon in advance (unless Mizar or LSI is advised by counsel
that any such announcement or other disclosure not mutually agreed upon in
advance is required to be made by law or the Takeover Code or applicable NMS
rule and then only after making a reasonable attempt to comply with the
provisions of this Section).

        5.11.    No Solicitations.
                 ----------------

        (a)      From the date hereof until the Closing Date or until this
Agreement is terminated or abandoned as provided in this Agreement, neither LSI
nor the LSI Subsidiaries shall directly or indirectly (i) solicit, initiate or
take part in discussions with, (ii) enter into negotiations or agreements with,
or (iii) furnish any information to, any corporation, partnership, person or
other entity or group (other than Mizar, an affiliate of Mizar or their
authorized representatives pursuant to this Agreement) concerning any formal or
informal proposal for a merger, sale of substantial assets, sale of shares of
stock or securities or other takeover or business combination transaction (an
"Acquisition Proposal") involving LSI or the LSI Subsidiaries, and LSI will
instruct its officers, directors, advisors and its financial and legal
representatives and consultants not to take any action contrary to the foregoing
provisions of this sentence; provided, however, that LSI may furnish (on terms
including confidentiality terms, substantially similar to those set forth in
that certain Letter of Intent between LSI and Mizar) information concerning its
business, properties or assets to a corporation, partnership, person or other
entity or group (a "Potential Acquirer") if (i) LSI's Board of Directors
determines that such Potential Acquirer is reasonably likely to submit a bona
fide offer to consummate an Acquisition Proposal on terms that would yield such
a higher value to LSI's stockholders if provided with confidential information
about LSI, and (ii) after consultation with counsel, LSI's Board of Directors
determines that the failure to provide such confidential information would
constitute a breach of its fiduciary duty to stockholders of LSI. Following
receipt of a bona fide offer from a Potential Acquirer proposing an Acquisition
Proposal, which offer the Board of Directors of LSI determines would likely
yield a higher value to the stockholders of LSI than will the Exchange, LSI may
with respect to such Potential Acquirer, negotiate and take any of the actions
otherwise prohibited by this Section 5.11 if, in the opinion of the Board of
Directors of LSI after consultation with counsel, the failure to negotiate with
such Potential Acquirer would constitute a breach by the Board of Directors of
its fiduciary duty to the stockholders of LSI. In the event LSI shall determine
to provide any information as described above, or shall receive any offer
relating to an Acquisition Proposal, (i) it shall promptly notify Mizar (a
"Notice of Proposal") as to the fact that information is to be provided or that
on offer relating to an Acquisition Proposal has been received and shall furnish
to Mizar the identity of the recipient of such information or the proponent of
such offer or proposal, if applicable, and, if an offer or proposal has been
received, a description of the material terms thereof, and (ii) Mizar shall be
permitted to take the same actions taken by LSI pursuant to this provision with


                                      32
<PAGE>
 
respect to any Potential Acquirer of Mizar, notwithstanding the fact that such
actions may otherwise be prohibited by this Section 5.11. LSI may enter into a
definitive agreement for an Acquisition Proposal with a Potential Acquirer with
which it is permitted to negotiate pursuant to this Section 5.11; provided,
however, that at least one business day prior to LSI's execution thereof LSI
shall have provided Mizar written notice (a "Notice Agreement") indicating LSI's
intent to enter into such agreement and describing all the material terms of
such agreement. Following the execution of such a definitive agreement, LSI or
Mizar may terminate this Agreement in accordance with Article IX hereof, subject
to the fee and expense reimbursement provisions of Section 9.2. LSI will notify
Mizar promptly in writing if LSI becomes aware that any inquiries or proposals
are received by, any information is requested from or any negotiations or
discussions are sought to be initiated with, LSI with respect to an Acquisition
Proposal, and LSI shall promptly deliver to Mizar any written inquiries or
proposals received by LSI relating to an Acquisition Proposal. LSI will notify
Mizar promptly if LSI becomes aware that any inquiries or proposals are received
by, any information is requested from or any negotiations or discussions are
sought to be initiated with, LSI or the LSI Subsidiaries with respect to an
Acquisition Proposal, and LSI shall promptly deliver to Mizar any written
inquiries or proposals received by LSI relating to an Acquisition Proposal. Each
time, if any, that the Board of Directors of LSI determines that it must enter
into negotiations with, or furnish any information that is not publicly
available to, any Potential Acquirer (other than Mizar, an affiliate of Mizar or
their authorized representatives) concerning any Acquisition Proposal, LSI will
give Mizar prompt notice of such determination (which shall include a copy of
the non-public information which LSI has delivered to such Potential Acquirer).

        (b) From the date hereof until the Closing Date or until this Agreement
is terminated or abandoned as provided in this Agreement, Mizar shall not
directly or indirectly (i) solicit, initiate or take part in discussions with,
(ii) enter into negotiations or agreements with, or (iii) furnish any
information that is not publicly available to, any corporation, partnership,
person or other entity or group (other than LSI, an affiliate of LSI or their
authorized representatives pursuant to this Agreement) concerning any
Acquisition Proposal involving Mizar, and Mizar will instruct its officers,
directors, advisors and its financial and legal representatives and consultants
not to take any action contrary to the foregoing provisions of this sentence;
provided, however, that Mizar may furnish (on terms including confidentiality
terms, substantially similar to those set forth in that certain Letter of Intent
between LSI and Mizar) information concerning its business, properties or assets
to a Potential Acquirer if (i) Mizar's Board of Directors is advised by its
financial advisor that such Potential Acquirer has the financial wherewithal to
consummate an Acquisition Proposal that would yield a higher value to Mizar's
stockholders than will the Exchange, (ii) Mizar's Board of Directors determines
that such Potential Acquirer is reasonably likely to submit a bona fide offer to
consummate an Acquisition Proposal on terms that would yield such a higher value
to Mizar's stockholders if provided with confidential information about Mizar,
and (iii) after consultation with counsel, Mizar's Board of Directors determines
that the failure to provide such confidential information would constitute a
breach of its fiduciary duty to stockholders of Mizar. Following receipt of a
bona fide offer from a Potential Acquirer proposing an Acquisition Proposal,
which offer the Board of Directors of Mizar determines would likely 


                                      33
<PAGE>
 
yield a higher value to the stockholders of Mizar than will the Exchange, Mizar
may with respect to such Potential Acquirer, negotiate and take any of the
actions otherwise prohibited by this Section 5.11 if, in the opinion of the
Board of Directors of Mizar after consultation with counsel, the failure to
negotiate with such Potential Acquirer would constitute a breach by the Board of
Directors of its fiduciary duty to the stockholders of Mizar. In the event Mizar
shall determine to provide any information as described above, or shall receive
any offer relating to an Acquisition Proposal, (i) it shall promptly notify LSI
(a "Notice of Proposal") as to the fact that information is to be provided or
that on offer relating to an Acquisition Proposal has been received and shall
furnish to LSI the identity of the recipient of such information or the
proponent of such offer or proposal, if applicable, and, if an offer or proposal
has been received, a description of the material terms thereof, and (ii) LSI
shall be permitted to take the same actions taken by Mizar pursuant to this
provision with respect to any Potential Acquirer of LSI, notwithstanding the
fact that such actions may otherwise be prohibited by this Section 5.11. Mizar
may enter into a definitive agreement for an Acquisition Proposal with a
Potential Acquirer with which it is permitted to negotiate pursuant to this
Section 5.11; provided, however, that at least one business day prior to Mizar's
execution thereof Mizar shall have provided LSI a Notice Agreement indicating
Mizar's intent to enter into such agreement and describing all the material
terms of such agreement. Following the execution of such a definitive agreement,
LSI or Mizar may terminate this Agreement in accordance with Article IX hereof,
subject to the fee and expense reimbursement provisions of Section 9.2. Mizar
will notify LSI promptly in writing if Mizar becomes aware that any inquiries or
proposals are received by, any information is requested from or any negotiations
or discussions are sought to be initiated with, Mizar with respect to an
Acquisition Proposal, and Mizar shall promptly deliver to LSI any written
inquiries or proposals received by Mizar relating to an Acquisition Proposal.
Each time, if any, that the Board of Directors of Mizar determines that it must
enter into negotiations with, or furnish any information that is not publicly
available to, any Potential Acquirer (other than LSI, an affiliate of LSI or
their authorized representatives) concerning any Acquisition Proposal, Mizar
will give LSI prompt notice of such determination (which shall include a copy of
the non-public information which Mizar has delivered to such Potential
Acquirer).

     5.12. Boards of Directors.
           -------------------

     LSI and Mizar shall use their reasonable best efforts to agree on a
mutually acceptable Board of Directors for each of LSI and Mizar. Both current
Boards of Directors shall take all action necessary to cause the Board of
Directors of Mizar and LSI, as applicable, on or before the Closing Date, to be
increased or decreased as necessary, and shall take all such other actions as
they deem necessary, to cause the persons so chosen to be appointed to the Mizar
and LSI Boards of Directors. If Mizar and LSI are unable to agree on the persons
to serve as the foregoing directors before the Closing Date, then two persons
shall be chosen by the present Board of Directors of Mizar (the "Mizar
Nominees"), and three persons shall be chosen by the present Board of Directors
of LSI (the "LSI Nominees"), and both LSI and Mizar shall use their reasonable
best efforts to cause the Mizar Nominees and the LSI Nominees to be elected as
directors of Mizar to replace the existing Board of Directors for a term
expiring at the first annual meeting of stockholders of Mizar following the
Closing Date. The current Board of Directors of

                                       34
<PAGE>
 
LSI shall nominate a person, who shall be chosen by the new Board of Directors
of Mizar, to serve on the LSI Board of Directors until his successor is duly
elected and qualified, and the current Board of Directors of LSI shall resign
effective at the time of such persons appointment.

     5.13. Corporate Government of the Companies After the Exchange. The
           --------------------------------------------------------
Board of Directors of Mizar and LSI shall take all actions necessary after the
Closing to do the following, including obtaining any necessary approvals of
their stockholders prior to the Closing:

           (a)   The Certificate of Incorporation of Mizar, as in effect on the
     Closing Date, shall continue in full force and effect, except that it shall
     be amended to change the corporate name of Mizar to a name mutually agreed
     upon by LSI and Mizar.

           (b)   The Bylaws of Mizar, as in effect as of the Closing Date, shall
     continue in full force and effect.

           (c)   The members of the Board of Directors of each of Mizar and LSI
     shall be as determined under Section 5.12. The officers of Mizar and LSI
     shall be the persons holding such offices as of the Closing Date.

     5.14. Pooling. From and after the date hereof and until the Closing
           -------
Date, neither Mizar nor LSI, nor any of their respective subsidiaries or other
affiliates, shall (i) knowingly take any action, or knowingly fail to take any
action, that would jeopardize the treatment of the Exchange as a "pooling of
interest" for accounting purposes or (ii) knowingly take any action, or
knowingly fail to take any action, that would jeopardize qualification of the
Exchange as a tax free transaction under the TCGA. In addition, both Mizar and
LSI shall use their reasonable best efforts to cause Mizar to obtain, prior to
the Closing Date, a letter from Arthur Andersen, dated the Closing Date and
addressed to Mizar, stating substantially to the effect that, based on such
firm's review of this Agreement and the other procedures set forth in such
letter, such firm concurs that the Exchange will qualify as a pooling of
interests transaction under Opinion 16 of the Accounting Principles Board.

           ---------------
action, suit, proceeding or investigation, whether civil, criminal or
administrative, including, without limitation, any such claim, action, suit,
proceeding or investigation in which any of the present or former officers or
directors of LSI, the LSI Subsidiaries or Mizar (collectively, the "Managers")
is, or is threatened to be, made a party by reason of the fact that he or she is
or was a stockholder, director, officer, employee or agent of LSI, the LSI
Subsidiaries or Mizar, or is or was serving at the request of LSI, the LSI
Subsidiaries or Mizar as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, whether
before or after the Closing Date, then (i) LSI and Mizar shall indemnify and
hold harmless, as and to the full extent permitted by applicable law (including
by advancing expenses promptly as statements therefor are received), each such
Manager against any losses, claims, damages, liabilities, costs, expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any such claim, action, suit, proceeding or investigation, and
in the event of any such claim, action, suit, proceeding or investigation
(whether arising before or after the Closing Date), (ii) if LSI or Mizar have
not promptly assumed the defense of such matter, the Managers may retain counsel
satisfactory to them, and LSI, and Mizar, shall pay all fees and expenses of
such counsel for the Managers promptly, as statements therefor are received, and
(iii) LSI, and Mizar, will use their respective best efforts to assist in the
vigorous defense of any such matter; provided that neither LSI nor Mizar shall
be liable for any settlement effected without its prior written consent (which
consent shall not be unreasonably withheld). Upon the determination that Mizar
is not liable for any such indemnification claims, the Manager will reimburse
Mizar and LSI, as applicable, for any fees, expenses and costs incurred by Mizar
or LSI in connection with the defense of such claims. Any Manager wishing to
claim indemnification under this Section 8.1, upon learning of any such claim,
action, suit, proceeding or investigation, shall immediately notify LSI and
Mizar thereof (provided that the failure to give such notice shall not affect
any obligations hereunder, except to the extent that the indemnifying party is
actually and materially prejudiced thereby). Mizar and LSI agree that all rights
to indemnification existing in favor of the Managers as in effect as of the date
hereof shall survive the Exchange. Mizar further covenants not to amend or
repeal any provisions of the governing charter documents of Mizar or of LSI in
any manner which would adversely affect the indemnification or exculpatory
provisions contained therein. The provisions of this Section 8.1 are intended to
be for the benefit of, and shall be enforceable by, each indemnified party and
his or her heirs and representatives.

delivered to LSI) (the "Indemnified Parties") to cover the Managers; provided,

however, that Mizar may substitute for such Mizar policies, policies with at
- -------
least the same coverage containing terms and conditions which are no less
advantageous to the Managers and provided that said substitution does not result
in any gaps or lapses in coverage with respect to matters occurring prior to the
Closing Date. The provisions of this Section 8.2 are intended to be for the
benefit of, and shall be enforceable by, each Manager and his or her heirs and
representatives.

     due to the failure of the terminating party to perform or observe the
     covenants, agreements, and conditions hereof to be performed or observed by
     it at or before the Closing Date; provided, that the non-breaching party's
     cause of action resulting from such failure to perform or to observe the

     Board of Directors as to its fiduciary duties to its stockholders such

Gentlemen:

        Reference is made to that certain Share Purchase Agreement, dated as of
November 17, 1997 (the "Agreement"), between Mizar, Inc., a Delaware corporation
("Mizar"), and Loughborough Sound Images Limited, a company registered in
England and Wales ("LSI"). Capitalized terms used herein shall have the
respective meanings set forth in the Agreement.

        In connection with the transactions contemplated by the Agreement, and
in consideration of the mutual covenants and agreements contained herein and for
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the parties hereto agree as follows:

        1. Subject to the terms and conditions contained herein, LSI hereby
waives Mizar's requirement under the Agreement to cause the Registration
Statement to become effective and consents to Mizar's withdrawal of the
Registration Statement.

        2. Subject to the terms and conditions contained herein, LSI hereby
waives the requirement that the shares of Mizar Common Stock to be issued in the
Exchange be approved for listing on the NMS as of the Closing Date; provided,
however, that Mizar covenants to cause such shares to be so approved for listing
on or before the effective date of the Registration Statement (as defined on
Schedule 1 hereto).

        3. LSI and Mizar hereby mutually consent to the extension of the
termination date in Section 9.1(b) from March 31, 1998 to April 30, 1998.

        4. Mizar hereby grants, effective from and after Closing, to the holders
of LSI capital stock (and their transferees and assigns) the registration rights
set forth on Schedule I hereto with respect to the shares of Mizar Common Stock
to be issued in the Exchange.

        5. For the purpose of enforcing the obligations set forth in paragraph 4
hereof, each of the holders of LSI capital stock (and their transferees and
assigns) shall be deemed a third party beneficiary of this Agreement.

        6. Mizar hereby represents and warrants that, (i) assuming that each of
the LSI shareholders are not U.S. persons or acquiring Mizar Common Stock on
behalf of any U.S. person, the issuance of shares of Mizar Common Stock to the
LSI stockholders in the Exchange is exempt from registration under the
Securities Act of 1933, as amended and (ii) Mizar is eligible to register the
shares of its Common Stock issued to the LSI stockholders for resale by them on
a continuous or delayed basis pursuant to a Registration Statement on Form S-3.

        7. Mizar agrees that it will deliver to LSI the opinion of its legal
counsel in form acceptable to counsel for LSI as to the matters described in
clause (i) of paragraph 6 above, in the form set forth on Schedule II hereto.

        Please indicate your acceptance of the foregoing terms by your execution
in the space provided below.

        Very truly yours,

                                                                      Schedule I

                               Registration Rights

      1. Upon the demand after the Closing of holders of at least 500,000 shares
of Mizar Common Stock to be issued in the Exchange, Mizar shall prepare and file
with the Securities and Exchange Commission ("SEC") a Registration Statement
("Registration Statement") under the Securities Act of 1933, as amended (the
"1933 Act") on Form S-3, or if for any reason Mizar is not then eligible to file
a Form S-3, then on Form S-1 registering all of the shares of Mizar Common Stock
issued in the Exchange (the "Registrable Securities") for resale to the public.

      In addition, each time prior to the "Termination Date" (defined below)
that Mizar decides to file a Registration Statement under the 1933 Act (other
than on Forms S-4 or S-8 or any successor form for the registration of
securities issued or to be issued in connection with a merger or acquisition or
employee benefit plan) covering the offer and sale by it or other holders of
Mizar's securities who may demand registration of such securities of any of its
securities for money, Mizar shall give written notice thereof to all holders of
Registrable Securities. Mizar shall include in such Registration Statement such
shares of Registrable Securities for which it has received written requests to
register such shares within 30 days after such written notice has been given. If
the Registration Statement is to cover an underwritten offering, such
Registrable Securities shall be included in the underwriting on the same terms
and conditions as the securities otherwise being sold through the underwriters.
If the managing underwriter(s) in any underwritten offering shall advise Mizar
in writing that the inclusion of all of the shares of Registrable Securities and
any other Mizar Common Stock requested to be registered would have an adverse
effect on the proposed distribution of the securities to be issued by Mizar in
such public offering, then the number of shares of Registrable Securities and
other Mizar Common Stock to be included in the offering (except for shares to be
issued by Mizar in an offering initiated by Mizar) shall be reduced to such
smaller number with the participation in such offering by the holders of
Registrable Securities to have priority over the participation by other holders
of Mizar Common Stock. In connection with any of the foregoing Registration
Statements, Mizar will as expeditiously as possible:

                  (a) use its best efforts to cause such Registration Statement
      to become effective and remain effective so that the Registrable
      Securities may be offered and sold on a continuous or delayed basis in
      accordance with Rule 415 under the 1933 Act, until the earlier of three
      years after the Closing Date or such time as all of the Registrable
      Securities have been sold by the holders of the Registrable Securities
      (the "Holders") under such Registration Statement or pursuant to Rule 144
      under the 1933 Act or until all such Registrable Securities are eligible
      for resale under the 1933 Act without volume limitations set forth in Rule
      144 (the "Termination Date");
<PAGE>
 
                  (b) prepare and file with the SEC such amendments and
      post-effective amendments to the Registration Statement, and such
      supplements to the Prospectus, as may be requested by the Holders, or as
      may be required by the 1933 Act or rules and regulations thereunder to
      keep the Registration Statement effective until all Registrable Securities
      covered by such Registration Statement are sold in accordance with the
      intended plan of distribution set forth in such Registration Statement or
      the prospectus forming a part thereof (the "Prospectus");

                  (c) deliver to the Holders, without charge, as many copies of
      each Prospectus as the Holders may reasonably request (Mizar hereby
      consenting to the use of each such Prospectus by the Holders in connection
      with the offering and sale of the Registrable Securities covered by such
      Prospectus) and a reasonable number of copies of the then-effective
      Registration Statement and any post-effective amendments thereto and any
      supplements to the Prospectus, including financial statements and
      schedules, all documents incorporated therein by reference and all
      exhibits (including those incorporated by reference);

                  (d) register or qualify or cooperate with the Holders and
      their counsel in connection with the registration or qualification of such
      Registrable Securities for offer and sale under the securities or blue sky
      laws of such jurisdictions as the Holders may reasonably designate in
      writing and do anything else necessary or advisable to enable the
      disposition in such jurisdictions of the Registrable Securities covered by
      the Registration Statement; provided that Mizar shall not be required to
      qualify generally to do business in any jurisdiction where it is not then
      so qualified or to take any action which would subject it to general
      service of process in any such jurisdiction where it is not then so
      subject;

                  (e) cause all such Registrable Securities to be listed on each
      securities exchange or automated quotation system on which similar
      securities issued by Mizar are then listed;

                  (f) advise each Holder, promptly after it shall receive notice
      or obtain knowledge thereof, of the issuance of any stop order by the SEC
      suspending the effectiveness of such Registration Statement or the
      initiation or threatening of any proceeding for such purpose and promptly
      use its reasonable best efforts to prevent the issuance of any stop order
      or to obtain its withdrawal if such stop order should be issued;

                  (g) at least three days prior to the filing of any amendment
      or supplement to such Registration Statement or prospectus or any document
      that is to be incorporated by reference into such Registration Statement
      or prospectus, furnish a copy thereof to each seller of such Registrable
      Shares;

                                       4
<PAGE>
 
              (h) notify the Holders at any time when a prospectus relating to
      such Registration Statement is required to be delivered under the 1933
      Act, of the happening of any event as a result of which the prospectus
      included in such Registration Statement, as then in effect, includes an
      untrue statement of a material fact or an omission to state a material
      fact required to be stated in a Registration Statement or Prospectus or
      necessary to make the statements in a Registration Statement or Prospectus
      not misleading (hereafter, a "Misstatement"). At the request of any such
      Holder, Mizar will promptly prepare (and, when completed, give notice to
      each Holder of Registrable Securities) a supplement or amendment to such
      prospectus so that, as thereafter delivered to the purchasers of such
      Registrable Securities, such prospectus will not contain an untrue
      statement of a material fact or omit to state any fact necessary to make
      the statements contained therein not misleading; provided that upon such
      notification by Mizar, each Holder of the Registrable Securities will not
      offer or sell Registrable Securities until Mizar has notified such Holder
      that it has prepared a supplement or amendment to such prospectus and
      delivered copies of such supplement or amendment to such Holder;

              (i) provide a transfer agent and registrar for all of the
      Registrable Shares not later than the effective date of such S-3
      Registration Statement; and

              (j) in connection with any underwritten offering enter into such
      customary agreements (including underwriting agreements in customary form)
      and take all such other actions as a majority of the Holders of the
      Registrable Securities being sold in such offering, or the underwriters,
      if any, reasonably request in order to expedite or facilitate the
      disposition of the Registrable Securities.

      2.      Based upon the written opinion of Mizar's securities law counsel,
Mizar may, by written notice to the Holders, for a period not to exceed 30 days,
suspend the Registration Statement and require that the Holders cease sales of
the Registrable Securities thereunder, if (i) Mizar is engaged in negotiations
or preparations for any transaction that Mizar desires to keep confidential for
valid business reasons, and (ii) Mizar determines in good faith that the public
disclosure requirements imposed on Mizar as a result of the Registration
Statement would require public disclosure of such negotiations or preparations;
provided, however, that Mizar may not exercise this right on more than one
occasion. Mizar will thereafter promptly prepare (and, when completed, give
notice to each Holder of Registrable Securities) a supplement or amendment to
such prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus will not contain an untrue statement of
a material fact or omit to state any fact necessary to make the statements
contained therein not misleading. Each Holder, in the event Mizar is issuing
shares of beneficial interest to the public in an underwritten offering, agrees,
if requested by the managing underwriter or underwriters for such 

                                       3
<PAGE>
 
underwritten offering, not to effect any public sale or distribution of
Registrable Securities or any securities convertible into or exchangeable or
exercisable for such Registrable Securities, including a sale pursuant to Rule
144 (or any similar provision then in force) under the 1933 Act or under any
other registration statement other than one pertaining to such underwritten
offering, during the 14 days prior to, and during the 90-day period beginning
on, the effective date of such underwritten offering, provided, however, that no
Holder shall be required to refrain from selling Registrable Securities more
than once in any twelve-month period.

      3. Mizar agrees to indemnify, to the extent permitted by law, each Holder
of Registrable Shares, its officers and directors and each person who controls
such Holder (within the meaning of the 1933 Act) against all losses, claims,
damages, liabilities and expenses (including attorneys' fees) caused by any
untrue or alleged untrue statement of material fact contained in any
Registration Statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any
information furnished in writing to Mizar by such Holder expressly for use
therein or by such Holder's failure to deliver a copy of the Registration
Statement or prospectus or any amendments or supplements thereto after Mizar has
furnished such Holder with a sufficient number of copies of the same. In
connection with the S-3 Registration Statement, each Holder of Registrable
Securities will furnish to Mizar in writing such information and affidavits as
Mizar reasonably requests for use in connection with any such registration
statement or prospectus. In addition, in consideration for the Registration
Rights granted to them hereby, each Holder will agree in writing with Mizar
that, to the extent permitted by law, such Holder will indemnify Mizar, its
directors and officers and each Person who controls Mizar (within the meaning of
the 1933 Act) against any losses, claims, damages and liabilities resulting from
any untrue statement of material fact contained in the S-3 Registration
Statement, prospectus or preliminary prospectus or any amendment thereof or
supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading, but only to the extent such untrue statement or omission is
contained in any information or affidavit so furnished in writing by such
Holder; provided that the obligation to indemnify will be individual to each
Holder and will be limited to the net amount of proceeds received by such Holder
from the sale of Registrable Securities pursuant to the S-3 Registration
Statement. Any person entitled to indemnification herein will (i) be required to
give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability 

                                       4
<PAGE>
 
for any settlement made by the indemnified party without its consent (but such
consent will not be unreasonably withheld). An indemnifying party who is not
entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim. The indemnification provided for under this Agreement
will remain in full force and effect regardless of any investigation made by or
on behalf of the indemnified party or any officer, director or controlling
person of such indemnified party and will survive the transfer of securities.
Mizar also agrees to make such provisions as are reasonably requested by any
indemnified party for contribution to such party in the event Mizar's
indemnification is unavailable for any reason.

      4. Mizar shall bear all expenses of the Registration Statement and all
other expenses incident to Mizar's compliance with this Agreement, which shall
include, without limitation, all registration and filing fees and expenses of
compliance with securities or blue sky laws, printing expenses, messenger and
delivery expenses, and fees and disbursements of counsel for Mizar and one
counsel for all of the Holders, and all independent certified public accountants
and other Persons retained by Mizar, Mizar's internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal and accounting duties), the expense of any annual audit or
quarterly review, the expense of any liability insurance for Mizar and its board
of directors and the expenses and fees for listing the securities to be
registered on each securities exchange on which similar securities issued by
Mizar are then listed but which shall not include any selling commissions or
underwriting discounts.

Gentlemen:

      We are counsel for Mizar, Inc., a Delaware corporation ("Mizar"), and are
representing it in connection with the transactions contemplated by the terms of
that certain Share Purchase Agreement, dated November 17, 1997 (the "Purchase
Agreement"), by and between Mizar and Loughborough Sound Images Limited, a
company registered in England and Wales ("LSI"), and the letter agreement dated
March 24, 1998 (the "Letter Agreement"), between Mizar and LSI. Capitalized
terms used herein shall have the definition given to such terms in the Purchase
Agreement. We have been requested by Mizar to render this opinion letter
pursuant to paragraph 7 of the Letter Agreement.

      For purposes of this opinion letter, we have examined and relied upon the
originals, or copies certified or otherwise identified to our satisfaction, of
such corporate documents and records of Mizar and certificates of public
officials and other documents, and have received such information, including
written certificates, from officers and representatives of Mizar, as we have
deemed necessary or appropriate to enable us to express the opinions expressed
below. In each case where we have relied upon such corporate documents,
information, or certificates, we believe such reliance is reasonable and have no
knowledge that the information provided is false, misleading, or otherwise
should not be relied upon.

      Based upon the foregoing, and subject to the assumptions, limitations, and
qualifications set forth below, we are of the opinion that:

      1.          The issuance to the LSI Shareholders of the shares of Mizar
                  Common Stock that are to be issued under the terms of the
                  Purchase Agreement (the "Shares"), when effected in accordance
                  with the terms thereof and of the Letter Agreement, is exempt
                  from registration under the Securities Act of 1933, as amended
                  (the "Securities Act").

      2.      The Shares, when issued in accordance with the terms of the Letter
              Agreement and the Purchase Agreement, will be duly and validly
              issued, fully paid and non-assessable.

      The opinions expressed herein are subject to the following assumptions,
limitations, and qualifications:

      A.      For purposes of the opinion rendered in paragraph 1, we have
assumed that (a) no offer or sale of the Shares is made to a person in the
United States, nor will any offer or sale be made for the account or benefit of
a person in the United States, (b) to Mizar's knowledge, each of the LSI
Shareholders are outside of the United States, and (c) Mizar implements the
appropriate "offering restrictions" required under the provisions of Regulation
S of the Securities Act.

      B.      For purposes of the opinions rendered herein, we have also assumed
(a) the genuineness of all signatures other than the signatures of
representatives of Mizar, (b) the authenticity of all documents submitted to us
as originals, (c) the conformity to authentic original documents of all
documents submitted to us as certified, conformed, or photostatic copies, (d)
the due authorization, execution, and delivery of all documents referred to in
this opinion by the parties to such documents other than Mizar, and (e) the
accuracy of all factual recitations contained in certificates or similar
documents examined by us.

      C.      The opinions expressed in this letter are based upon the law in
effect on the date hereof, and we assume no obligation to revise or supplement
this opinion should such law be changed by legislative action, judicial
decision, or otherwise.

      This opinion letter is being furnished to you solely for your benefit and
only with respect to the transactions recited herein. Accordingly, it may not be
relied upon by, or quoted in any manner or delivered to, any person or entity
without, in each instance, our prior written consent.

                                               Very truly yours,

                                      -2-
