                                AND SUBSIDIARIES

              Notes to Condensed Consolidated Financial Statements

1.  The financial information furnished herein has not been audited by
    independent accountants; however, in the opinion of management, all
    adjustments (only consisting of normal recurring accruals) necessary for a
    fair presentation of the results of operations for the three month period
    ending September 30, 1998 have been included.

2.  On May 22, 1997, Watson General Corporation (Watson) completed the private
    placement of $7 million 10% Senior Subordinated Notes Due 2002 and 7,304,520
    shares of its common stock (the Private Placement). In connection with the
    valuation of the common stock issued in the transaction, an original issue
    discount of $1,000,000 was recorded. Approximately $17,000 of the discount
    is amortized into interest expense monthly.

    Interest on the Senior Subordinated Notes is 10% per annum for the first
    year, payable quarterly, and increases by one percent each year during the
    term of the Notes. As of September 30, 1998 the interest rate was 11%. At
    the option of the Company, interest payments due can be converted to debt
    under the same terms as the original principal. During the quarter ended
    September 30, 1998, the Company converted interest due of $212,000 to long
    term debt. In addition, if on the earlier of (i) the third anniversary of
    the date of the Securities Purchase Agreement or such other date thereafter
    designated by the Investors, (ii) the date of a stock offering or (iii) a
    sale of the Company (the "Adjustment Date"), the Company's cumulative
    adjusted earnings before taxes, depreciation and amortization ("EBTDA") fail
    to meet specific projections provided by the Company to the Investors,
    additional interest is payable in the form of warrants to the Investors. If
    the resulting actual percentage of EBTDA per share is less than 70% of the
    projected amount, an adjustment to interest expense is calculated and
    warrants are issued in an amount equal to the additional interest expenses
    divided by the fair market value of the common stock on the Adjustment Date.
    The adjusted interest rate cannot exceed 29.76%. Due to the lower than
    expected performance in fiscal 1998, the Company determined it was unlikely
    to meet these projections in the future. Accordingly, the Company recorded
    interest expense on the Senior Subordinated Notes at a rate of 29.76% as of
    the beginning of the agreement and reflected the adjustment as a change in
    accounting estimate. Therefore interest in the first quarter of 1998 is
    accrued at 10% while interest for the first quarter of fiscal year 1999 is
    recorded at 29.76%. The Company reflected additional interest as warrants to
    be issued.

    On December 17, 1997, the Company obtained $3.75 million in financing from
    BankBoston and used the proceeds to, among other things, acquire all of the
    outstanding common stock of Advanced Tank Certification, Inc. (ATC),
    pursuant to stock purchase agreements between the Company and all of the
    shareholders of ATC. The ATC acquisition was accounted for using the
    purchase method. 

3.  Inventory consists of tank gauge equipment and is accounted for using the 
    weighted average method.

4.  Included in interest expense on the Statements of Operations is amortization
    of the original issue discount and deferred debt costs. These amounts are
    shown as depreciation and amortization on the Statements of Cash Flows.

5.  Certain amounts for the prior period have been reclassified to conform to
    the current quarter presentation.

6.  Due to the Company's loss position, diluted net loss per share is the same
    as basic earnings per share as the result would be antidilutive.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

Results of Operations:

In the first quarter of fiscal 1999 the Company reported a net loss of $743,000
or $0.04 per share as compared to a net loss of $554,000 or $0.03 per share in
the prior year. Sales for the quarter were $1,523,000 compared with $1,560,000
in the prior year. The 2% decrease in sales from the same quarter in the prior
year is due primarily to the sale of Toxguard Fluid Technologies, Inc.
("Toxguard") which was divested as part of the Company's strategic plan in
January 1998. Toxguard's revenue represented approximately 13% of the Company's
total revenues in the same period of the prior year. Although revenues
decreased, gross margins remained relatively consistent compared to the same
period of prior year. This is due to an expected corresponding decrease in cost
of sales. The Company's strategic plan calls for it to reposition itself in
pursuit of its most significant market opportunity, leak detection/monthly
monitoring of underground storage tanks.


Included in the loss of $743,000 for the quarter is $558,000 of interest expense
related to the Senior Subordinated Notes (see Note 2 of the Notes to
Consolidated Financial Statements). Of the total interest, $212,000 was 
converted to long term debt and $346,000 represents warrants to be issued.

The Company's depreciation and amortization decreased 7% compared to the same
period in prior year due to the write off of certain proprietary software during
the prior fiscal year. Selling, general and administrative expenses decreased by
34% due to the reduction of expenses incurred in the prior year related to the
merger of USTMAN Industries, Inc. and Watson General Corporation and the
Advanced Tank Certification, Inc. acquisition. These expenses consisted
primarily of fees for relocating offices, severance of terminated employees,
exit costs, attorneys' fees, and accounting fees. Management believes the
selling, general and administrative expenses will continue throughout the fiscal
year at the lower level.

The Company's sales depend in part upon its customers' decisions as to when and
how to implement measures to meet the December 22, 1998 Environmental Protection
Agency ("EPA") underground storage tank compliance requirements. These
requirements require, among other things, some form of permanent monthly
monitoring of underground storage tanks. The Company believes that the market
for its services may accelerate as compliance deadlines approach.

Financial Condition and Liquidity:

At September 30, 1998 the Company's current liabilities exceeded current assets
by $695,000 compared to $636,000 at June 30, 1998. This is a result of the
current portion of long term debt on the BankBoston term loan. The Company's
business does not require material ongoing capital expenditures. The Company's
management believes that it has adequate resources for the next twelve months
of operations.                                                            

Except for historical information contained herein, the statements in this
report are forward-looking statements that are made pursuant to the safe harbor
provisions of the Private Securities Litigation Reform Act of 1995.
Forward-looking statements involve known and unknown risks and uncertainties
which may cause the actual results in future periods to differ materially from
forecasted results. These risks and uncertainties include, among other things,
product demand, customers' strategies regarding the December 22, 1998 EPA
compliance requirements, and market competition.
