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

The following discussion provides information which management believes is
relevant to an assessment and an understanding of the Company's operations and
financial condition. This discussion should be read in conjunction with the
condensed consolidated financial statements and accompanying notes.

Forward-looking Statements

       Statements in this filing which are not historical facts are forward-
looking statements under the provisions of the Private Securities Litigation
Reform Act of 1995. All forward-looking statements involve risks and
uncertainties. These statements are based upon numerous assumptions about future
conditions that could prove not to be accurate. Actual events, transactions or
results may materially differ from the anticipated events, transactions or
results described in such statements. The Company's ability to consummate such
transactions and achieve such events or results is subject to certain risks and
uncertainties. In addition to those specifically mentioned above, such risks and
uncertainties include, but are not limited to, the existence of demand for and
acceptance of the Company's products and services, regulatory approvals and
developments, economic conditions, the impact of competition and pricing,
results of financing efforts and other factors affecting the Company's business
that are beyond the Company's control. The Company undertakes no obligation and
does not intend to update or revise these forward-looking statements to reflect
future events or circumstances.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2000 COMPARED TO THREE MONTHS ENDED MARCH 31, 1999:

Revenue for the three months ended March 31, 2000 was $6,002,000 compared to
$7,515,000 for the three months ended March 31, 1999, resulting in a $1,513,000
or a 20.1% decrease. The decrease was primarily the result of reduced revenues
on the ESM Receiver contract with the U.S. Navy. This contract generated 28.6%
of the revenue for the three months ended March 31, 1999 compared to 5.7% of the
revenue for the three months ended March 31, 2000.

The total amount of negotiated backlog, including both unfilled firm orders for
the Company's products for which funding had been authorized and appropriated by
the customer, and firm orders for which funding had not been appropriated as of
March 31, 2000 and 1999 was $15,000,000 and $17,000,000 respectively. This
decrease is principally the result of reduced unappropriated backlog. The
Company is in negotiation for an additional authorization of approximately
$5,000,000 on a major subcontract with the U.S. Navy. However, there can be no
assurance that the negotiations will be successful.

Cost of revenue, as a percentage of revenue, decreased from 74.4% for the three
months ended March 31, 1999 to 69.9% for the three months ended March 31, 2000.
The decrease primarily resulted from continuing productivity improvements in the
operations and in the profit margins under current contracts.

For the three months ended March 31, 2000, general and administrative expenses
decreased from $1,225,000 to $1,023,000 resulting in a $202,000 or a 16.5%
decrease compared to the three month period ended March 31, 1999. The decrease
was due principally to shedding of inefficiencies in the current year.

                                       9
<PAGE>   10

Net interest income was $13,000 for the three months ended March 31, 2000,
compared to net interest expense of $24,000 for the three months ended March 31,
1999. The Company was able to utilize its improved operating performance and the
net proceeds from the sale of real estate on December 1, 1998, to reduce to zero
its outstanding balance on its line of credit throughout the three-month period
ended March 31, 2000, and earned interest on temporary cash investments.

Income tax expense consists of federal and state income tax. The Company's
effective tax rate was 37.3% for the three months ended March 31, 2000, compared
to an effective tax rate of 38.5% for the three months ended March 31, 1999. The
rate varied from the statutory rate primarily due to state taxes.

Net income for the three months ended March 31, 2000 increased to $498,000,
compared to a net income of $415,000 for the three months ended March 31, 1999.
The increase of $83,000 was the result of the items discussed above.

SIX MONTHS ENDED MARCH 31, 2000 COMPARED TO SIX MONTHS ENDED MARCH 31, 1999:

Revenue for the six months ended March 31, 2000 was $11,495,000 compared to
$13,538,000 for the six months ended March 31, 1999, resulting in a $2,043,000
or 15.1% decrease. The decrease was primarily the result of reduced revenues on
the ESM Receiver contract with the U.S. Navy. This contract generated 33.0% of
the revenue for the six months ended March 31, 1999 compared to 10.8% of the
revenue for the six months ended March 31, 2000.

Cost of revenue, as a percentage of revenue, decreased from 75.5% for the six
months ended March 31, 1999 to 72.9% for the six months ended March 31, 2000.
The decrease primarily resulted from an improved mix of business and
productivity improvements in the operations.

For the six months ended March 31, 2000, general and administrative expenses
decreased from $2,116,000 to $1,820,000 or a 14.0% decrease compared to the
six-month period ended March 31, 1999. The decrease was due principally to a
decrease in salaries and related benefit expense.

Net interest income was $43,000 for the six months ended March 31, 2000,
compared to net interest expense of $70,000 for the six months ended March
31,1999. The Company was able to utilize its improved operating performance and
the net proceeds from the sale of real estate on December 1, 1998, to pay down
its outstanding balance on its line of credit throughout the three-month period
ended March 31, 2000, and earned interest on temporary cash investments.

Income tax expense consists of federal and state income tax. The Company's
effective tax rate was 37.6% for the six months ended March 31, 2000, compared
to an effective tax rate of 38.9% for the six months ended March 31, 1999. The
rate varied from the statutory rate primarily due to state taxes.

Net income for the six months ended March 31, 2000 increased to $838,000,
compared to a net income of $691,000 for the six months ended March 31, 1999.
The increase of $147,000 was the result of the items discussed above.

LIQUIDITY AND SOURCES OF CAPITAL

Cash flows used in operating activities were $374,000 for the six months ended
March 31, 2000, compared to cash flows provided by operating activities of
$1,797,000 during the comparable six month period of fiscal year 1999. This
decrease was principally due to the prepayment of income taxes, an increase in
unbilled receivables, and terminating a deferred compensation plan, which
resulted in a payout to participants.

The net cash used for investing activities during the six-month period ended
March 31, 2000 was $274,000, compared to net cash provided to the Company by its
investing activities of $1,209,000 during the first six months of fiscal year
1999. In the six months ended March 31, 1999, the Company disposed of property
held for sale for $1,446,000. The current period expenditures were related to
the acquisition of property and equipment. The Company anticipates that it will
continue to incur capital expenditures at this approximate rate through the end
of the fourth quarter of fiscal year 2000.

The net cash provided by the Company in financing activities during the
six-month period ended March 31, 2000 was $73,000, compared to net cash used by
the Company in financing activities of $2,269,000 during the comparable
six-month period of fiscal year 1999. The 2000 activity was principally the
result of the proceeds of stock option exercises offset by the payment of
capital lease obligations. For the six month period ended March 31, 1999, the
net cash used was primarily devoted to reducing to zero the Company's line of
credit and satisfying the mortgage on the real estate which was sold. At March
31, 2000, the Company was in compliance with the covenants contained in the line
of credit agreement, and there were no amounts outstanding.

The Company believes that its existing funds, amounts generated by operations,
and amounts available for borrowings under its line of credit will be sufficient
to meet its working capital needs through the next 12 months.
