                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE 1 - BASIS OF PRESENTATION

    In the opinion of the management of the Company, the accompanying
consolidated financial statements reflect all adjustments (consisting only of
normally recurring accruals) which are necessary for a fair presentation of the
Company's results of operation and changes in financial position for the interim
periods presented. These financial statements should be read in conjunction with
the Company's annual report on Form 10-KSB for the year ended December 31, 1996.


NOTE 2 - EQUITY

    In 1997 and 1996, the Company established stock option plans (the "Plans")
for certain management and directors, pursuant to which the Company granted
750,000 and 1,100,000 options, respectively. In March 1997, the Company issued
89,954 shares of its Common Stock, par value $.001 per share ("Common Stock") 
upon the exercise of a portion of the options under the Plans in exchange for 
accrued salaries and fees totaling approximately $345,000.

NOTE 3 - EARNINGS PER SHARE

     Earnings (loss) per share is computed on the basis of the weighted average
number of common shares outstanding during the periods. The assumed exercise of
all outstanding stock options has been excluded from the computation of
earnings (loss) per share because the result was antidilutive. Also, the 
computation of earnings (loss) per share includes preferred stock dividends of
$87,500 for the three months ended March 31, 1997.

NOTE 4 - NEW ACCOUNTING PRONOUNCEMENTS

     In March 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128 ("SFAS 128") "Earnings Per Share." The
Company will implement the disclosure requirements of SFAS 128 as required.

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


         ALL AMOUNTS USED HEREIN ARE IN THOUSANDS.



RESULTS OF OPERATIONS

    NET SALES. Net sales of $4,111 for the three months ended March 31, 1997
decreased $1,015 or 19.8% as compared with net sales of $5,126 for the three
months ended March 31, 1996. The decrease in the current year period was due
principally to the lower volume of large press drive sales, combined with
decreased net selling prices at the Company's Dynamatic subsidiary as compared
with the prior year period.

    GROSS INCOME. Consolidated gross income of $1,395 or 33.9% to sales for the
first quarter of 1997 decreased 39.5% compared with consolidated gross income of
$2,306 or 45.0% to sales for the first quarter of 1996. The decrease is
primarily due to lower sales in the current year quarter which resulted in
higher unabsorbed burden and lower net selling prices in the current year
period.

    SELLING AND ADMINISTRATIVE EXPENSE. Selling and administrative expense, as a
percent to net sales, increased to 32.8% to sales in the first quarter of 1997
as compared with 27.6% to sales in the prior year quarter. The increase is
principally due to lower net sales, partially offset by a slight decrease in
administrative expenses.

    RESEARCH AND DEVELOPMENT EXPENSE.  Research and development expense of $138
or 3.4% to sales in the current year quarter increased $70 or 102.9% as compared
with $68 or 1.3% to sales in the prior year quarter. The


<PAGE>   6



increase is primarily a result of expenditures relative to development of the
Company's emission testing products.

LIQUIDITY AND CAPITAL RESOURCES

    The Company has financed its operating requirements and capital expenditures
through cash flows from operations and financing arrangements.

    At March 31, 1997, the Company's working capital was approximately $2,226,
compared to working capital of approximately $1,077 at December 31, 1996. This
increase is principally due to borrowings on long-term debt which were used to
reduce current liabilities and the exchange of accrued salaries and fees for
shares of the Company's Common Stock. At March 31, 1997, the Company had
approximately $63 available under its existing line-of-credit arrangements.


                           PART II. OTHER INFORMATION


ITEM 2.  CHANGES IN SECURITIES.

     Effective March 10, 1997, the Company granted to certain officers,
directors and employees options to purchase a total of 750,000 shares of the
Company's Common Stock at a price of $6.00 per share. The options are
exercisable at any time during the five years after grant. During the first
quarter of 1997, two officers exercised options to purchase a total of 39,856
shares of Common Stock in exchange for approximately $129,500 in accrued
salary. In addition, three directors who were owed approximately $216,000 in
legal fees and consulting fees exercised options to purchase a total of 50,098
shares of Common Stock in exchange for such fees owed.
