         1.       BASIS OF PRESENTATION

         The accompanying condensed consolidated financial statements of the
Company have been prepared without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information
and footnote disclosures normally included in financial statements prepared
in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to such rules and regulations. The condensed
consolidated balance sheet as of December 31, 1999 was derived from audited
financial statements. The accompanying condensed consolidated financial
statements should be read in conjunction with the audited consolidated
financial statements and notes thereto included in the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 1999.

         The financial information included herein reflects all adjustments
(consisting of normal recurring adjustments) which are, in the opinion of
management, necessary for a fair presentation of the results for the interim
period. The results of operations for the three and six months ended June 30,
2000 are not necessarily indicative of the results to be expected for the
full year. Certain prior year reclassifications have been made in order to
conform to current year presentation.

         The Company uses a 52 to 53-week fiscal year ending on the Friday
closest to December 31. The Company also follows a thirteen-week quarterly
cycle. The six-month periods ended on June 30, 2000 and July 2, 1999.

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

         The following discussion should be read in conjunction with the
Company's Unaudited Condensed Consolidated Financial Statements and Notes
thereto included elsewhere in this Quarterly Report on Form 10-Q.

         This Report contains certain forward-looking statements and information
relating to the Company that are based on the beliefs of management as well as
assumptions made by and information currently available to management. The words
"anticipates," "believes," "estimates," "expects," "plans," "intends," and
similar expressions, as they relate to the Company or its management, are
intended to identify forward-looking statements. Such statements reflect the
current views of the Company, with respect to future events and are subject to
certain risks, uncertainties and assumptions, that could cause actual results to
differ materially from those expressed in any forward-looking statement,
including, without limitation: competition from other manufacturers in the
Company's aerospace, flooring or commercial product lines, loss of key
employees, general economic conditions and adverse factors impacting the
aerospace industry such as changes in government procurement policies. Should
one or more of these risks or uncertainties materialize, or should the
underlying assumptions prove incorrect, actual results may vary materially from
those described herein as anticipated, believed, estimated or expected. The
Company does not intend to update these forward-looking statements.

RESULTS OF OPERATIONS

         The Company operates within one industry segment, elastomer products,
and is organized into two business segments: BurkeMercer and Engineered
Polymers. The Company's products are organized into three product groups:
Aerospace and Defense Products, which produces precision silicone seals and
other products used on commercial and military aircraft; Flooring Products,
which produces and distributes rubber and vinyl cove base and other floor
covering accessory products; and Commercial Products, which produces various
intermediate and finished silicone and organic rubber products.

         The following table sets forth certain income statement information for
the Company for the three month period ended June 30, 2000 compared to the three

</TABLE>


COMPARISON OF THE THREE-MONTH PERIOD ENDED JUNE 30, 2000 VERSUS THE THREE-MONTH
PERIOD ENDED JULY 2, 1999.

         NET SALES. Total net sales decreased 4.3%, from $28.4 million for the
three-month period ended July 2, 1999 to $27.2 million for the same period in
2000. Aerospace and Defense Products sales decreased 16.0%, from $7.8 million
for the three-month period ended July 2, 1999 to $6.6 million for the same
period in 2000, due to a decrease in demand for commercial and military
products. Flooring Products net sales decreased 2.1% from $12.2 million for the
three-month period ended July 2, 1999 to $11.9 million for the same period in
2000, due to lower demand for vinyl flooring and cove base products. Commercial
Products sales increased 3.2%, from $8.4 million for the three-month period
ended July 2, 1999 to $8.7 million for the same period in 2000. The increase in
sales as compared to the prior year was the result of stronger demand for
commercial silicone specialty products.

         COST OF SALES. Cost of sales decreased 6.2%, from $20.2 million for the
three-month period ended July 2, 1999 to $19.0 million for the same period in
2000. As a percentage of net sales, gross profit increased from 28.8% for the
three-month period ended July 2, 1999 to 30.1% for the same period in 2000. The
improved gross profit percentage was due to an improved sales mix resulting from
a greater proportion of net sales of higher margin Flooring and Commercial
Products in the three-month period.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 24.1%, from $4.2 million for the three-month
period ended July 2, 1999 to $5.2 million for the same period in 2000. As a
percentage of net sales, selling, general and administrative expenses increased
from 14.7% for the three-month period ended July 2, 1999 to 19.1% for the same
period in 2000. The increase in expenses was due to increased shipping and
warehousing costs and one-time expenses associated with the recent management
reorganization within the Company.

         AMORTIZATION OF GOODWILL. Amortization of goodwill was $0.5 million for
the three-month period ended June 30, 2000, which was unchanged from the same
period in 1999.

                                       9

         INCOME FROM OPERATIONS. As a result of the above factors, income from
operations decreased 28.2%, from $3.5 million for the three-month period ended
July 2, 1999 to $2.5 million for the same period in 2000.

         INTEREST EXPENSE. Interest expense increased from $3.8 million for the
three-month period ended July 2, 1999 to $4.0 million for the same period in
2000. The increase is due to the Company's use of its Credit Facility during the
quarter, and the interest expense associated with the capital lease for the
Company's new computer system which was entered into in March of 1999.

         NET LOSS. As a result of the above factors, net loss increased from
$0.2 million for the three-month period ended July 2, 1999 to a loss of $1.5
million for the same period in 2000.


COMPARISON OF THE SIX-MONTH PERIOD ENDED JUNE 30, 2000 VERSUS THE SIX-MONTH
PERIOD ENDED JULY 2, 1999.

         NET SALES. Total net sales decreased 3.9%, from $57.1 million for the
six-month period ended July 2, 1999 to $54.9 million for the same period in
2000. Aerospace and Defense Products sales decreased 16.1%, from $16.9 million
for the six-month period ended July 2, 1999 to $14.2 million for the same period
in 2000, due to decreases in demand for commercial and military products.
Flooring Products net sales increased 1.2%, from $23.1 million for the six-month
period ended July 2, 1999 to $23.4 million for the same period in 2000, due to
higher demand for both vinyl and rubber flooring and cove base products.
Commercial Products sales increased 1.4%, from $17.0 million for the six-month
period ended July 2, 1999 to $17.2 million for the same period in 2000. The
increase in sales as compared to the prior year was the result of higher demand
for the Company's commercial silicone specialty products.

         COST OF SALES. Cost of sales decreased 4.5%, from $40.7 million for the
six-month period ended July 2, 1999 to $38.9 million for the same period in
2000, due primarily to the decrease in net sales. As a percentage of net sales,
gross profit increased from 28.7% for the six-month period ended July 2, 1999 to
29.2% for the same period in 2000. The increase in gross profit percentage was
due to an improved sales mix resulting from a higher proportion of net sales of
the higher margin Flooring and Commercial Products in the six month period. The
improved sales mix helped offset the impact of the year on year reduction in net
sales of Aerospace and Defense products, which have a high proportion of fixed
operating expenses.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 18.7%, from $8.7 million for the six-month
period ended July 2, 1999 to $10.3 million for the same period in 2000. As a
percentage of net sales, selling, general and administrative expenses increased
from 15.2% for the six-month period ended July 2, 1999 to 18.8% for the same
period in 2000. The increase in expenses was due to increased shipping and
warehousing costs and one-time costs associated with the recent management
reorganization within the Company.

         AMORTIZATION OF GOODWILL. Amortization of goodwill was $1.0 million for
the six-month period ended June 30, 2000, which was unchanged from the same
period in 1999.

         INCOME FROM OPERATIONS. As a result of the above factors, income from
operations decreased 30.2%, from $6.7 million for the six-month period ended
July 2, 1999 to $4.7 million for the same period in 2000.

                                     10

<PAGE>

         INTEREST EXPENSE. Interest expense increased from $7.5 million for the
six-month period ended July 2, 1999 to $7.9 million for the same period in 2000.
The increase is due to the debt service associated with the Company's use of its
Credit Facility during the quarter, and the interest expense associated with the
capital lease for the Company's new computer system which was entered into in
March of 1999.

         NET LOSS. As a result of the above factors, net loss increased from
$0.5 million for the six-month period ended July 2, 1999 to a loss of $3.3
million for the same period in 2000.

INCOME TAX PROVISION (BENEFIT)

         For the three and six month periods ended June 30, 2000, the Company
did not record an income tax provision due to operating losses.

LIQUIDITY AND CAPITAL RESOURCES

         CASH FLOW. The Company's principal uses of cash are to finance working
capital, capital expenditures for property, plant and equipment, internal growth
and debt service.

         CAPITAL REQUIREMENTS. The Company expects to spend approximately $2.0
million during 2000 on capital expenditures not directly related to
acquisitions. Cash flow from operations, to the extent available, may also be
used to fund a portion of any acquisition expenditures. The Company anticipates
that its principal use of cash during 2000 will be working capital requirements,
capital expenditures and debt service requirements. Based upon current and
anticipated levels of operations, the Company believes that its cash flow from
operations, together with amounts available under the Credit Facility (described
below), will be adequate to meet its anticipated requirements for the
foreseeable future for working capital, capital expenditures and interest
payments.

         SOURCES OF CAPITAL. Under a Loan and Security Agreement with
NationsBank, N.A., as administrative agent, and other lending institutions party
thereto, the Company has a borrowing capacity of $25.0 million (the "Credit
Facility"). The Credit Facility matures in August 2002. Interest on loans under
the Credit Facility bear interest at rates based upon either, at the Company's
options, Eurodollar Rates plus a margin of 2.5% or upon the Prime Rate. Loans
under the Credit Facility are secured by security interests in substantially all
of the assets of the Company and are guaranteed by any and all current or future
subsidiaries of the Company, which guarantees are secured by substantially all
of the assets of such subsidiaries. The Credit Facility contains customary
covenants restricting the Company's ability to, among other things, incur
additional indebtedness, create liens or other encumbrances, pay dividends or
make other restricted payments, make investments, loans and guarantees or sell
or otherwise dispose of a substantial portion of assets to, or merge or
consolidate with, another entity. The Credit Facility also contains a number of
financial covenants that will require the Company to meet certain ratios and
tests and provide that a change of control of the Company (as defined in the
Credit Facility) will constitute an event of default.

ITEM 3.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

         As reported by the Company in its Annual Report on Form 10-K for the
