                          INDEPENDENT AUDITORS' REPORT

To The Board of Directors and Stockholders
NexStar Automation, Inc. and Subsidiary
Longmont, CO

We have audited the consolidated balance sheets of NexStar Automation, Inc. and
Subsidiary as of December 31, 1995 and 1994, and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1995. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of NexStar Automation,
Inc. and Subsidiary as of December 31, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995 in conformity with generally accepted accounting principles.

We have reviewed the accompanying balance sheet of NexStar Automation, Inc. and
consolidated subsidiary as of March 31, 1996 and the related statements of
operations and cash flows for the three months ended March 31, 1996 and 1995 for
the three months. These financial statements are the responsibility of the
Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying financial statements for them to be in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (AMOUNTS EXPRESSED IN UNITED STATES DOLLARS)

NOTE 1 - INTERIM  FINANCIAL STATEMENTS (UNAUDITED)

In the opinion of Nexstar Automation, Incorporated and Subsidiary (the
"Company"), the accompanying unaudited consolidated financial statements contain
all adjustments (consisting of only normal recurring accruals) necessary to
present fairly the financial position of the Company at March 31, 1996 and the
results of their operations and changes in cash flows for the three months ended
March 31, 1996 and 1995. The results of operations for the three months ended
March 31, 1996 and 1995 are not necessarily indicative of the results to be
expected for the full year.

NOTE 2 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company is engaged in the business of designing, assembling, customizing,
installing and supporting production automation systems, which typically
incorporate customized robotics. The Company's focus is directed toward the data
storage, medical/pharmaceutical and food processing industries. The Company
commenced operations on January 4, 1993.

In April of 1994, FBA Ventures Ltd. ("FBA") acquired all the issued and
outstanding common shares of NexStar Corporation ("NexStar") in exchange for
2,700,000 shares of common stock of FBA, of which 2,525,000 shares held in
escrow. For financial reporting purposes, the business combination was accounted
for as an additional capitalization of the Company (a reverse acquisition with
NexStar as the acquirer). NexStar is considered the surviving entity. The
historical financial statements prior to the merger are those of NexStar. The
stockholders of NexStar received 2,700,000 shares of FBA stock for an
approximate 58% interest in the new combined entity. FBA's only assets consisted
of cash and funds advanced to NexStar.

ESCROW AGREEMENT

According to the purchase agreement, 2,525,000 shares of FBA common stock are to
be placed in escrow with the Escrow Agent for the Shareholder. In September of
1994, 224,015 shares were released leaving 2,300,985 escrow shares as of
December 31, 1994. The shareholders may exercise all voting rights of these
shares with certain restrictions. Under the escrow agreement, the shares may be
released annually, on a pro rata basis based on the Company's cumulative cash
flow. In the event that any escrow shares are not released from escrow before
December 31, 2004, those escrow shares are to be canceled. The escrow shares are
presented as outstanding in these financial statements as management believes
they will all be released from escrow.

NOTE 2 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

PRINCIPLES OF CONSOLIDATION

The 1995 and 1996 consolidated financial statements include the accounts of
NexStar Automation, Inc. and Subsidiary, a Canadian corporation and its wholly
owned subsidiary NexStar Corporation (a Colorado corporation). All significant
intercompany balances and transactions have been eliminated in consolidation.

RECONCILIATION OF CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING
PRINCIPLES

The differences between generally accepted accounting principles used in Canada
(Canadian GAAP) and the United States (U.S. GAAP) do not significantly impact
the financial statements of the Company for all periods presented. All amounts
are expressed in United States dollars.

INVENTORY

Inventory is stated at the lower of cost or market and primarily consists of
purchased raw materials and work in process. Cost is determined using the
first-in, first-out (FIFO) method.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Replacements, renewals and
improvements are capitalized and costs for repairs and maintenance are expensed
as incurred. Depreciation is computed using the straight-line method over the
estimated useful lives of five years.

ORGANIZATION COSTS

Organization costs are all business start-up costs incurred by the Company.
These costs have been capitalized and are being amortized over a five-year
period.

DEFERRED OFFERING COSTS

Deferred offering costs represent costs incurred in connection with the
Company's proposed public offering in the United States. Deferred offering costs
will be offset against net proceeds, if successful, or expensed in operations if
the offering is unsuccessful.

REVENUE RECOGNITION

Revenue from automation projects is accounted for under the
percentage-of-completion method, using labor costs incurred to date in relation
to estimated total labor costs of the contracts to measure the stage of
completion. The cumulative effects of revisions of estimated total contract
costs and revenues are recorded in the period in which the facts requiring the
revision become known. When a loss is anticipated on a contract, the full amount
thereof is provided currently. The differences between amounts billed and
revenue recognized is shown as revenue in excess of billings and deferred
revenue on the accompanying balance sheets.

Totals of revenue earned billings on uncompleted contracts are as follows:

liquid cash investments with original maturity dates of three months or less to
be cash equivalents.

Actual results could differ from those estimates.

In fiscal 1994, the Company entered into $65,000 line-of-credit agreement with a
bank. During 1995, the line-of-credit was renewed to provide up to $150,000 of

line-of-credit were $0 and $52,700 at December 31, 1995 and 1994, respectively.
The line is collateralized by the Company's savings account and guaranteed by
the Company's President. The line accrues interest at 7%.

NOTE 7 - INCOME TAXES

Effective for the year ended December 31, 1994, the Company adopted the
provisions of Statement of Financial Accounting Standards No. 109 "Accounting
for Income Taxes" (SFAS 109) which requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
difference between the financial statements and tax basis of assets and
liabilities using the enacted tax rates in effect for the year in which the
difference is expected to reverse. The measurement of deferred tax assets is
reduced, if necessary, by the amount of any tax benefits that, based on
available evidence, are not expected to be realized.

are depreciation for tax purposes in excess of depreciation for financial
reporting purposes as well as other items being amortized for financial
reporting purposes which are currently deductible for tax purposes.
