                         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 - DEFERRED REVENUE

    Deferred revenue of $175,000 at June 30, 1997 represents advance payments
received from customers.  The anticipated shipment date for these customer
orders is the third quarter of 1997.

NOTE 3 - EQUITY

    In 1997 and 1996, the Company established stock option plans (the "Plans")
for certain management and directors, pursuant to which the Company issued
750,000 and 1,100,000 options, respectively.  In March 1997, the Company issued
89,954 shares of its Common Stock, par value $.001 ("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.  In June 1997, the Company
issued 13,462 shares of its Common Stock in exchange for accrued salary
totalling approximately $42,000.

NOTE 4 - 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 and $175,000 for the three and six months ended June 30, 1997.

NOTE 5 - 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.

NOTE 6 - SUBSEQUENT EVENT

    In August 1997 the Company entered into an agreement to acquire Hicklin
Engineering, Inc., a leading developer and manufacturer of transmission and
drive-train component dynamometers and test systems, in exchange for 400,000
shares of the Company's Common Stock.  The acquisition is expected to be closed
in August 1997.

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 $7,895 for the six months ended June 30, 1997
decreased $1,267 or 13.8% as compared with net sales of $9,162 for the six
months ended June 30, 1996.  The decrease in the current year period was due
principally to the lower volume of large press drive sales, combined with lower
net selling prices at Dynamatic Corporation ("Dynamatic"), a wholly-owned   
subsidiary of the Company, as compared with the prior year period.  This
decrease was partially offset by sales of the Company's emissions testing
products in the six months ended June 30, 1997. Net sales of $3,784 in the
second quarter of 1997 decreased $252 or 6.2% as compared with net sales of
$4,036 in the second quarter of 1996.  The decrease was due primarily to lower
sales volume in the traditional Dynamatic product lines, combined with lower
net selling prices, partially offset by sales of the Company's emission testing
products in the current year quarter.

        GROSS INCOME.  Consolidated gross income of $2,539 or 32.2% to sales
for the six months ended June 30, 1997 decreased 32.1% compared with
consolidated gross income of $3,737 or 40.8% to sales for the six months ended
June 30, 1996.  In the second quarter of 1997, consolidated gross income of
$1,145 or 30.3% to sales decreased 20.0% compared with consolidated gross
income of $1,431 or 35.5% to sales in the second quarter of 1996.  The decrease
is primarily due to lower sales volume in the current year periods which
resulted in higher unabsorbed burden and lower net selling prices in the
current year periods.

         SELLING AND ADMINISTRATIVE EXPENSE.  Selling and administrative
expense, as a percent to net sales, increased to 39.7% and 36.1% for the second
quarter and first six months of 1997, compared to 30.0% and 28.5% for the
second quarter and first six months of 1996, respectively.  The increase is
principally due to lower net sales combined with higher selling expenses
relative to the Company's emission testing products.

         RESEARCH AND DEVELOPMENT EXPENSE.  Research and development expense of
$252 or 3.2% to sales for the six months ended June 30, 1997 increased $22 or
9.6% as compared with $230 or 2.5% to sales in the six months ended June 30,
1996.  Research and development expenses are primarily 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 June 30, 1997, the Company's working capital was approximately
$2,467, 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 fund inventory requirements for the Company's emission testing
products, the issuance of Common Stock and the exchange of accrued salaries and
fees for shares of the Company's Common Stock.  At June 30, 1997, the Company
had approximately $100 available under its existing line-of-credit
arrangements.
