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 JUNE 30, 2000 COMPARED TO THREE MONTHS ENDED JUNE 30, 1999:

Revenue for the three months ended June 30, 2000 was $6,257,000 compared to
$6,669,000 for the three months ended June 30, 1999, resulting in a $412,000
or a 6.2% decrease. The decrease was primarily the result of reduced revenues
on the ESM Receiver contract with the U.S. Navy.  This contract generated
18.1% of the revenue for the three months ended June 30, 1999 compared to
1.3% of the revenue for the three months ended June 30, 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 June 30, 2000 and 1999 was $6,632,000 and $13,900,000,
respectively.  This decrease is principally the result of delays in receiving
newly negotiated contract funding and the substantial completion of the ESM
Receiver contract.

Cost of revenue, as a percentage of revenue, decreased from 70.5% for the
three months ended June 30, 1999 to 65.2% for the three months ended June 30,
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 June 30, 2000, general and administrative expenses
increased from $1,075,000 to $1,396,000 resulting in a $321,000 or a 29.8%
increase compared to the three-month period ended June 30, 1999.  The
increase was due to an increase in severance costs in the current quarter.

Net interest income was $43,000 for the three months ended June 30, 2000,
compared to net interest income of $9,000 for the three months ended June 30,
1999. The increase was due to the absence of any outstanding debt in higher
daily cash equivalent balances during the current quarter.

                                        9
<PAGE>   10

Income tax expense consists of federal and state income tax.  The Company's
effective tax rate was 37.8% for the three months ended June 30, 2000,
compared to an effective tax rate of 38.7% for the three months ended June
30, 1999.  The rate varied from the statutory rate primarily due to state
taxes.

Net income for the three months ended June 30, 2000 decreased to $512,000,
compared to a net income of $551,000 for the three months ended June 30,
1999. The decrease of $39,000 was the result of the items discussed above.

NINE MONTHS ENDED JUNE 30, 2000 COMPARED TO NINE MONTHS ENDED JUNE 30, 1999:

Revenue for the nine months ended June 30, 2000 was $17,752,000 compared to
$20,207,000 for the nine months ended June 30, 1999, resulting in a
$2,455,000 or 12.1% decrease. The decrease was primarily the result of
reduced revenues on the ESM Receiver contract with the U.S. Navy.  This
contract generated 28.0% of the revenue for the nine months ended June 30,
1999, compared to 7.4% of the revenue for the nine months ended June 30,
2000.

Cost of revenue, as a percentage of revenue, decreased from 73.8% for the
nine months ended June 30, 1999 to 70.1% for the nine months ended June 30,
2000. The decrease primarily resulted from an improved mix of business and
productivity improvements in the operations.

For the nine months ended June 30, 2000, general and administrative expenses
increased from $3,191,000 to $3,216,000 or a .7% increase compared to the
nine-month period ended June 30, 1999. The increase is due to a one-time
severance cost of $461,500 recorded in the third quarter. Without
consideration of this one-time non-recurrent severance cost, the general and
administrative expense would have been $2,754,500, a decrease of 13.7%,
compared to the nine-month period ending June 30, 1999.

Net interest income was $86,000 for the nine months ended June 30, 2000,
compared to net interest expense of $61,000 for the nine months ended June
30,1999. 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 June 30, 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 37.7% for the nine months ended June 30, 2000,
compared to an effective tax rate of 38.8% for the nine months ended June 30,
1999.   The rate varied from the statutory rate primarily due to state taxes.

Net income for the nine months ended June 30, 2000 increased to $1,350,000,
compared to a net income of $1,241,000 for the nine months ended June 30,
1999.  The increase of $109,000 was the result of the items discussed above.

LIQUIDITY AND SOURCES OF CAPITAL

Cash flows used in operating activities were $582,000 for the nine months ended
June 30, 2000, compared to cash flows provided by operating activities of
$4,507,000 during the comparable nine-month period of fiscal year 1999. This
decrease was principally due to the payment 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 nine-month period ended
June 30, 2000 was $224,000, compared to net cash provided to the Company by
its investing activities of $1,133,000 during the first nine months of fiscal
year 1999. In the nine months ended June 30, 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 used by the Company in financing activities during the
nine-month period ended June 30, 2000 was $114,000, compared to net cash used
by the Company in financing activities of $2,229,000 during the comparable
nine-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 nine-month period ended June 30, 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 June 30, 2000, the Company was in compliance with the covenants contained
in the line of credit agreement, and there were no amounts outstanding
thereunder.

The Company currently 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.
