Note 2 - Deferred Revenue

Revenues for sales and the associated cost of goods sold are recognized when
product is shipped and no significant obligation remains. Revenues for
maintenance service contracts are recognized on a monthly basis ratable over the
period of the contracts. Cash payments received and billings in advance of
revenue recognition are recorded as a liability and recognized as revenue is
earned over the life of the contracts.

Note 3 - Use of Estimates

The preparation of consolidated financial statements in conformity with general
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Note 4 - Interim Financial Information

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10Q. Accordingly, they
do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments (consisting of normal recurring items) considered
necessary for a fair presentation have been included. Operating results for the
interim period are not necessarily indicative of the results that may be
expected for the fiscal year. For further information, refer to the consolidated
financial statements and footnotes thereto included in the Company's annual
report on Form 10-K.

Note 5 - Earnings Per Share

The Financial Accounting Standard Board has issued Statement No. 128, "Earnings
per Share" which supersedes APB Opinion No. 15. Statement No. 128 requires the
presentation of basic and diluted earnings per share amounts. Diluted per share
amounts assume the conversion, exercise or issuance of all potential common
stock instruments unless the effect is to reduce a loss or increase the income
per common share from continuing operations. The Company has adopted Statement
No. 128 for the periods ended June 30, 2000. All prior earnings per share
amounts have been restated to conform to the new Statement.

The weighted average number of common shares and common share equivalents
outstanding during the three-month period used to compute basic and diluted
earnings per share is as follows:

                    GENERAL AUTOMATION, INC. AND SUBSIDIARIES

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

The discussion in this document contains trend analysis and other forward
looking statements within the meaning of Section 27A of the Securities Act of
1933 as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended. Actual results could differ materially from those projected in the
forward-looking statements throughout this document. Items which could affect
results expected include product acceptance, timely releases of new products,
liquidity and financial condition of the Company.

(1)   MATERIAL CHANGES IN FINANCIAL CONDITION:

At the quarter ended June 30, 2000 the financial condition of the Company
remains strained with signs of deterioration. The Company's net working capital
deficit grew from a negative $6.8 million at September 30, 1999 to a negative
$8.4 million at June 30, 2000. Total shareholder deficit also grew from $7.5
million at September 30, 1999 to a negative $8.7 million at June 30, 2000
reflecting the losses reported year to date.

The Company continues to consider fundamental balance sheet management and
improvement in all of the key financial ratios to be a high priority matter for
the immediate future. The Company has for all of fiscal 2000 been shifting the
focus of its core business from database software sales and related hardware
sales, to a new line of internally developed e-commerce, web-enabling computer
software sales. These products are designed to assist the multi-value customers,
or Pick base customers, to migrate to a web-enabled business strategy for their
future growth in the e-commerce arena. As these products are developed, the
Company's legacy business continues to decline as resources are shifted from
marketing the Pick database products, to the new technology discussed above. As
a result, revenues for the quarter ended June 30, 2000 as well as the year to
date revenues, continue to decline, reflected in the almost 50% decline in the
Company's accounts receivable. The decline in accounts receivable is the most
noteworthy of the change in balance sheet accounts.

Subsequent to the quarter ended June 30, 2000 the Company sold its multi-value
database business and technology to Pick Systems, Inc. of Irvine, CA. On August
2, 2000, General Automation, Inc. ("GA") sold its line of Pick-based database
management products and related assets for $2,500,000 in cash, a Promissory Note
in the principal amount of $500,000 and royalties in an amount equal to 20% of
certain sales made by Pick Systems during the twenty-four month period
commencing August 1, 2000. The Note does not bear interest and is due and
payable in full on December 31, 2000.

The assets sold to Pick Systems consisted of (a) the line of products previously
sold by GA under the names R83, R91, Mentor Operating Environment (MOE), Mentor
PC/OS, mv.Base, mv.Enterprise, mv.PRO, Sequoia PICK, Sequoia PRO, PICK O/A, CIE
PICK and PICK64+; (b) all intellectual property unique to those products,
including trademarks; (c) the service contracts related to those products; (d)
all accounts receivable derived from service contracts pertaining to those
products, and (e) certain other related assets. (see SEC Form 8-K dated August
14, 2000) (see SEC Form 8-K dated August 14, 2000. Management stated in that 8-K
filing that the proforma effect on the Company's financial statements will be
filed at a later date in an amended 8-K filing).

The Company's cash position, and cash-flow from operations continue to be a
concern for management. The Company managed to retire the $2.2 million in debt
owed to its primary lender, Comerica Bank, subsequent to the quarter ended June
30, 2000 from proceeds received from the sale of its database business to Pick
Systems (discussed above). However, the Company will need to raise cash from
outside sources, either through debt or equity transactions, in order to
maintain the liquidity necessary for daily operations. Management continues to
work with lenders and hopes to replace the credit line at Comerica Bank with
another lender, though no assurances can be made that those efforts will prove
successful.

(2)   MATERIAL CHANGES IN RESULTS OF OPERATIONS:

As discussed above, the Company has been shifting resources and efforts to
internally developed proprietary software and away from its database software
for fiscal 2000. As a result, the Company is reporting declines in its revenues
for the quarter ended June 30, 2000 to $4.8 million versus $7.3 million, and for
the nine months ended June 30, 2000 of $17.1 million versus $22.7 million. As
the Company continues to transition to its focus of selling proprietary
web-enabling software, Management expects this declining trend to continue until
those products are marketed and shipped. It is the Company's goal to complete
those marketing and sales efforts in the fourth quarter of fiscal 2000 and into
fiscal 2001, through the exact timing of delivery is uncertain.



                                       7
<PAGE>   8

Cost of sales and the related gross profit margins have remained relatively
unchanged between the comparative periods. On a going forward basis, management
expects those costs and gross margins will improve as high-margin software
sales begin to replace lower-margin hardware and service revenues. As
previously discussed, it is the intention of management to focus its future
business primarily towards software sales.

Costs and Expenses, though showing an increase for the quarter ended June 30,
2000 over the same quarter in 1999, are down for the nine months ended June 30,
2000 versus the nine months ended June 30, 1999. The significant increases for
the current periods are primarily centered in marketing costs (included in the
Selling & Administrative Expenses) and research & development. In previously
filed Forms 10-Q's for fiscal 2000 management indicated that the Company expects
to continue investing in technology and the marketing of that technology as it
enters the e-commerce economy. Management expects that trend to continue
throughout the remainder of fiscal 2000 and into 2001.

The Company is reporting a net operating loss of $1.0 million versus a profit of
$326K for the three months ended June 30, 2000. For the nine months ended June
30, 2000 the total operating loss is reported at $1.9 million versus a $1.1
million profit for the same period in 1999. Total net losses for the three and
nine months periods ended June 30, 2000 is reported at $1.3 ($0.10 per share)
and $2.6 million ($0.21 per share) respectively. Profits of $88K ($.01 per
share) and $417K ($0.04) were reported for the three and nine month comparable
periods in 1999. Management attributes the losses for the current periods to the
previously discussed revenue declines and increased marketing and R&D expense.
