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

This Form 10-Q contains certain forward-looking statements. For this purpose,
any statements contained in this Form 10-Q that are not statements of historical
fact may be deemed to be forward- looking statements. Without limiting the
foregoing, words such as "may," "will," "expect," "believe," "anticipate,"
"estimate" or "continue" or the negative or other variations thereof or
comparable terminology are intended to identify forward-looking statements.
These statements by their nature involve substantial risks and uncertainties,
and actual results may be materially different. It is not reasonably possible to
itemize all of the many factors and specific events that could affect the
outlook of the Company's operations. Some factors that could cause actual
results to differ materially include, but are not limited to, product demand and
market acceptance risks, commercialization and technological difficulties,
capacity and supply constraints or difficulties, general economic conditions,
business conditions in the testing and packaging industry, and competitive
factors.


Results of Operations

Sales for the quarter ended June 30, 1998, were $3,795,772 down 9 percent from
second quarter 1997 sales of $4,189,050. The decrease in second quarter sales is
primarily the result of decreases in the sales volume of the Company's
permeation and weighing products, offset somewhat by general price increases.

Sales for the six-month period ended June 30, 1998, decreased 11 percent to
$7,343,208, compared to $8,253,052 for the first six months of 1997. The 11
percent decrease is primarily due to decreases in the sales volume of the
Company's permeation and weighing products, offset somewhat by increases in the
sales volume of the Company's packaging products, and general price increases.

The Company's permeation product group sales totaled $2,577,852 in the second
quarter of 1998, compared to $2,920,507 in the second quarter of 1997. The group
accounted for 68 percent of the Company's total second quarter 1998 sales,
compared with 70 percent in the second quarter of 1997. Permeation product group
sales for the six-month period ended June 30, 1998, were $5,055,276, or 69
percent of total sales, versus $6,071,755, or 74 percent of sales for the same
period in 1997.

Gross profit for the quarter and the six-month period ended June 30, 1998, was
64 and 65 percent of sales, respectively. This compares with 68 percent for both
the quarter and six-month period ended June 30, 1997. The decrease in gross
profit margin was due to reduced economies of scale due to the decline in sales
volume.

Selling, general and administrative expenses were 43 percent of sales for the
second quarter of 1998, compared to 31 percent for the second quarter of 1997.
Selling, general and administrative expenses were 42 and 31 percent for the
six-month periods ending June 30, 1998 and 1997, respectively . The increase in
general and administrative expenses was primarily attributable to the litigation
fees incurred to protect confidential information of the Company. These expenses
are expected to be substantially reduced in the third quarter of 1998.


                                        5

<PAGE>


Research and development expenses as a percent of sales were 8 percent for the
quarter and 7 percent for the six-month period ended June 30, 1998, compared to
8 percent for the same periods in 1997. Continued research and development
expenditures are necessary as the Company develops new products to expand in its
niche markets. For the foreseeable future, the Company expects to allocate on an
annual basis approximately 6 to 9 percent of sales to research and development.

Investment income increased approximately $7,000 in the second quarter of 1998
as compared to the second quarter of 1997. For the six months ended June 30,
1998, investment income decreased approximately $221,000. The increase for the
second quarter is primarily the result of higher average investment balances in
1998. The decrease in investment income for the six-month period is primarily
the result of a one-time gain of approximately $235,000 realized on the sale of
equity securities in the first quarter of 1997.

The Company's provision for income taxes was 34 percent of income before income
taxes for the six-month period ending June 30, 1998. The Company reviews the tax
rate quarterly and may make adjustments to reflect changing estimates. Based on
current operating conditions and income tax laws, the Company expects the
effective tax rate for all of 1998 to be in a range of 33 to 35 percent.

Net income decreased 55 percent to $396,802 for the second quarter of 1998,
compared to $884,400 for the second quarter of 1997. Basic net income per share
was $.06 for the second quarter of 1998, compared to $.14 for the same period in
1997. For the six-month period ended June 30, 1998, net income decreased 51
percent to $896,373 compared to $1,844,657 for the six-month period ended June
30, 1997. Basic net income per share was $.14 and $.29 for the six-month periods
ended June 30, 1998, and 1997, respectively.


Liquidity and Capital Resources

The Company continues to maintain a strong financial position. Total cash,
temporary cash investments and marketable securities increased approximately
$273,000 during the six months ended June 30, 1998. The Company used cash
resources to pay dividends of approximately $645,000 during the first six months
of 1998.

The Company has no long-term debt or material commitments for capital
expenditures as of June 30, 1998. The Company's plant and equipment do not
require any major expenditures to accommodate a significant increase in
operating demands. The Company anticipates that a combination of its existing
cash, temporary cash investments and marketable securities, plus an expected
continuation of cash flow from operations, will continue to be adequate to fund
operations, capital expenditures and dividend payments in the foreseeable
future.


Year 2000 Compliance

The Company has considered the potential impact of Year 2000 issues on its
business, operations, and financial condition. The Company does not have a
comprehensive or formal Year 2000 plan for its operations. However, the
Company's analysis of its existing systems indicates a majority are Year 2000
compliant. Specific systems which are subject to Year 2000 exposure and require
remediation have been identified.



                                        6

<PAGE>


The Company has plans to upgrade and test these systems by June 30, 1999, and
believes that these systems will function properly with respect to dates in the
year 2000 and thereafter. The Company is primarily relying on its vendors to
implement Year 2000 compliance with respect to the third-party software sold or
used by the Company.

To date, the cost associated with Year 2000 readiness has been immaterial and
the Company anticipates that costs related to this issue will not have a
material impact on their financial condition. Some risks associated with the
year 2000 issue are beyond the ability of the Company to control, including the
extent to which the Company's suppliers and service providers identify and
remedy potential Year 2000 issues. As a result, the Company may incur unexpected
expenditures in connection with the Year 2000 compliance.
