     Washington. IST pioneered the development of laser heating technology in
     thermoluminescence dosimetry (TLD) systems for personal radiation
     protection. The technology has potential uses in radiation therapy, nuclear
     waste management, radiation processing, environmental and radiation-hard
     electronics applications in government, medicine and the nuclear industry.

D.   On February 15, 1996, the company consummated the purchase of certain
     assets of Turner Engineering Technology (Turner) of Roanoke, Texas. Turner
     specializes in accelerated test methods for determining the quality of
     semiconductor wafers at various stages of manufacturing. These test methods
     are designed to save semiconductor manufacturers money by providing process
     control feedback to allow optimization and continued semiconductor process
     improvement.

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results

        of Operations.
        --------------

                            (In Thousands of Dollars)

Results of Operations
- ---------------------

Third Quarter 1996 Compared with Third Quarter 1995
- ---------------------------------------------------

Net income for the third quarter of fiscal 1996 was $761, or $.10 per share,
which decreased from $1,494, or $.20 per share, in last year's quarter. The
decrease in earnings was the result of continued investments in a number of new
business initiatives. Net spending before taxes on new business was
approximately $2,900 in the third quarter of fiscal 1996 versus $1,700 in last
year's quarter.

Net sales of $29,403 increased 1 percent from $28,975 in the prior year's third
quarter. The slight increase resulted from continued strong demand for the
company's bench-top instruments offset by decreases in shipments of the
company's PC-based board level products and automatic parametric test systems.
The company also reported the first shipment of Quantox(TM), the company's oxide
monitoring system designed for semiconductor wafer manufacturers.
Geographically, sales within the United States and Europe increased while sales
to the Pacific Basin region were down. Orders for the third quarter of 1996 of
$27,489 decreased 6 percent from the prior year's quarter. The Instruments
business unit continued to do well; however, orders for the company's automatic
parametric test systems and PC-based boards were down. Backlog was reduced
$1,995 during the quarter to $10,626 at June 30, 1996.

Cost of goods sold as a percentage of net sales increased slightly to 38.7
percent from 38.4 percent. The effect of the company's hedging activities on
cost of goods sold for the quarter was to decrease cost of goods sold by 0.2
percentage points of net sales versus an increase of 0.4 percentage points in
the prior year's quarter. Cost of goods sold as a percentage of net sales is
expected to increase as shipments of Quantox increase.

Selling, general and administrative expenses of $11,985 for the third quarter
increased $336, or 3 percent from $11,649 in the prior year's quarter. Lower
general and administrative expenses were offset by higher marketing expenses.
Lower general and administrative expenses are the result of lower incentive
compensation costs due to lower than plan earnings. Higher marketing costs were
due to costs associated with the exploration of new business opportunities,
including the marketing of Quantox.

Product development expenses of $4,664, or 15.8 percent of net sales for the
quarter, increased $812, or 21 percent from $3,852, or 13.3 percent of net sales
in the prior year's quarter. This was due primarily to higher personnel and
related costs associated with the study and development of new products and
technologies.

Amortization expense increased $55 to $171 from $116 in last year's quarter.
This is due to the amortization of goodwill associated with the acquisitions
discussed in Notes C and D.

Nine Months Ended June 30, 1996 Compared with Nine Months Ended June 30, 1995
- -----------------------------------------------------------------------------

Net income of $3,391, or $.43 per share for the nine months ended June 30, 1996,
increased $233, or 7 percent from $3,158, or $.42 per share on a fully diluted
basis reported for the prior year. This was the result of higher sales during
the first nine months of fiscal 1996 versus 1995 offset somewhat by higher
expenses and a higher tax rate. Pretax net spending on new business initiatives
was approximately $3,100 higher during the nine months ended June 30, 1996 than
last year's nine month period.

Net sales of $89,245 increased $8,895, or 11 percent from $80,350 reported for
the nine month period last year. The increase was due mainly to increased sales
of the company's bench-top instruments and strong demand for the company's
products serving the semi conductor industry. Orders for the nine month period
were up 7 percent from the same period last year. The majority of the 
increase was due to the company's bench-top instruments, along with $2,226 in
orders for Quantox, partially offset by lower orders for the company's PC-based
board level products and automatic parametric test systems.

Cost of goods sold as a percentage of net sales decreased to 38.3 percent from
38.7 percent for the nine month period last year. The company's hedging
activities had no effect on cost of goods sold for the nine months ended June
30, 1996, versus an increase in cost of goods sold by 0.3 percentage points of
net sales in last year's nine month period. Cost of goods sold as a percentage
of net sales is expected to increase as shipments of Quantox increase.

Selling, general and administrative expenses of $36,263, or 40.6 percent of net
sales increased $3,052, or 9 percent from $33,211, or 41.3 percent of net sales
in the same period in the prior year, due primarily to higher marketing costs.
The increased marketing costs related to the market development and introduction
of Quantox and increased personnel and related costs.

Product development expenses of $13,096, or 14.7 percent of net sales for the
period, increased $2,348, or 22 percent from $10,748, or 13.4 percent of net
sales last year. This was due to increased personnel and developments costs
associated with the company's next generation parametric test system introduced
in the second quarter, the development of its new bench-top instruments products
and the exploration of other new business opportunities.

Amortization expense of $462, increased $114 from $348 last year. This is due to
the amortization of goodwill associated with the acquisitions discussed in Notes
C and D.

Financing expenses (net of investment income) decreased $222, or 29 percent
despite higher average debt levels during the period. This was due to lower
interest rates on the variable rate debt and the absence of certain fees related
to the pay-off of a higher interest rate loan in the prior year's second
quarter.

The effective tax rate was 28.0 percent for the nine month period compared with
25.0 percent for the prior year's period. The effective rate is less than the
statutory rate of 34 percent due to the utilization of foreign tax credits and
foreign sales corporation (FSC) benefits. The effective tax rate was higher in
1996 than in 1995 because of additional utilization of foreign tax credit
carryforwards in 1995.

Liquidity and Capital Resources
- -------------------------------

Cash used in operations was $1,045 for the third quarter. For the first nine
months, cash provided by operations was $675. Total debt of $11,392 at June 30,
1996, increased $5,279 since the beginning of the year. The increase in debt
funded the company's increase in capital spending and supported increased
working capital requirements due to higher sales. Through interest rate swap
agreements, the company has effectively fixed its long-term interest rate at
under 7 percent for $6,000 of debt. The balance of debt carries variable
interest rates based on U.S. prime, LIBOR or FIBOR. The debt-to-capital ratio at
June 30, 1996, was 22.0 percent.

The company expects to increase capital spending during 1996 and estimates
capital spending will total approximately $3,500 for the fourth quarter. The
increased spending is being used to expand production capacity and facilities.
The Company expects to finance capital spending through cash provided by
operations as well as utilizing its available lines of credit. At June 30, 1996,
the Company had available unused lines of credit with domestic and foreign banks
aggregating $20,103 of which $6,372 were short term and $13,731 were long term.
