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: silicone and organic products. The

COMPARISON OF THE THREE MONTH PERIOD ENDED OCTOBER 1, 1999 VERSUS THE THREE
MONTH PERIOD ENDED OCTOBER 2, 1998

         NET SALES. Total net sales decreased 13.1%, from $30.9 million in 1998
to $26.8 million in 1999. Aerospace and Defense Products sales decreased 35.7%,
from $8.1 million in 1998 to $5.2 million in 1999, due to decreases in demand
for civil aerospace products, and deferral of demand for military products.
Flooring Products sales decreased 5.4%, from $13.4 million in 1998 to $12.7
million in 1999, due to lower demand. Commercial Products sales decreased 4.4%,
from $9.3 million in 1998 to $8.9 million in 1999, due to lower demand for
organic membrane products.

         COST OF SALES. Cost of sales decreased 7.8%, from $21.6 million in 1998
to $19.9 million in 1999. As a percentage of net sales, gross profit decreased
from 30.0% in 1998 to 25.8% in 1999. The decline in profitability was primarily
due to the decrease in sales volume of Aerospace and Defense Products.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 8.5%, from $4.3 million in 1998 to $4.6
million in 1999. As a percentage of net sales, selling, general and
administrative expenses increased from 13.8% to 17.3% in 1999. The increase in
spending was due to costs associated with the implementation of a new
information system. The increase in spending as a percentage of net sales was
due to the decrease in net sales.

         AMORTIZATION OF GOODWILL. Amortization of goodwill was unchanged, at
$0.5 million in 1998 and 1999.

         INCOME FROM OPERATIONS. As a result of the above factors, income from
operations decreased 60.5%, from $4.5 million in 1998 to $1.8 million in 1999.


                                       9

<PAGE>

         INTEREST EXPENSE. Interest expense decreased 4.2%, from $3.8 million in
1998 to $3.6 million in 1999.

         NET INCOME. As a result of the above factors, net income decreased from
$0.4 million in 1998 to a loss of $1.1 million in 1999.

COMPARISON OF THE NINE MONTH PERIOD ENDED OCTOBER 1, 1999 VERSUS THE NINE MONTH
PERIOD ENDED OCTOBER 2, 1998.

         NET SALES. Total net sales increased 3.5%, from $81.1 million in 1998
to $83.9 million in 1999. Aerospace and Defense Products sales decreased 15.1%,
from $26.1 million in 1998 to $22.1 million in 1999, due to decreases in demand
for civil aerospace products, which were partially offset by increases in demand
for military products. Flooring Products sales increased 17.5%, from $30.5
million in 1998 to $35.9 million in 1999, due to the acquisition of Mercer.
Commercial Products sales increased 5.8%, from $24.5 million in 1998 to $25.9
million in 1999, because of increased demand for the Company's organic
custom-mixed products and volume associated with new silicone hose products
introduced late in the second quarter of 1998.

         COST OF SALES. Cost of sales increased 5.9%, from $57.2 million in 1998
to $60.6 million in 1999. As a percentage of net sales, gross profit decreased
from 29.4% in 1998 to 27.8% in 1999. The decline in profitability was primarily
due to the decrease in sales volume of Aerospace and Defense Products in the
third quarter of 1999.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased 18.7%, from $11.2 million in 1998 to $13.3
million in 1999. As a percentage of net sales, selling, general and
administrative expenses increased from 13.9% to 15.9%. The increase in spending
was due to the acquisition of Mercer, and the costs associated with the
implementation of a new information system. The increase in percentage was also
due to the acquisition of Mercer, because Flooring Products have higher
distribution costs than the Company's other product groups.

         AMORTIZATION OF GOODWILL. Amortization of goodwill increased 66.8%,
from $0.9 million in 1998 to $1.5 million in 1999. The increase was due to the
acquisition of Mercer.

         INCOME FROM OPERATIONS. As a result of the above factors, income from
operations decreased 27.7%, from $11.7 million in 1998 to $8.5 million in 1999.

         INTEREST EXPENSE. Interest expense increased 10.7%, from $10.1 million
in 1998 to $11.1 million in 1999. The increase was due to the issuance of the
Floating-Rate Notes on April 21, 1998.

         NET INCOME. As a result of the above factors, net income decreased from
$1.0 million in 1998 to a loss of $1.6 million in 1999.

INCOME TAX PROVISION (BENEFIT)

         For the three month period ended October 1, 1999, the Company did not
book a tax provision due to operating loss. For the six month period ended July
2, 1999 the Company recorded an income tax benefit of $0.3 million. The
effective tax rate for the three and nine month periods ended October 2, 1998
differs from the federal statutory rate primarily due to state income taxes (net
of federal benefit).

LIQUIDITY AND CAPITAL RESOURCES

         CASH FLOW. The Company's principal uses of cash are to finance working
capital and capital expenditures related to asset acquisitions and internal
growth.

         CAPITAL REQUIREMENTS. The Company expects to spend approximately $2.5
million during 1999 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.

         SOURCES OF CAPITAL. Under a Loan and Security Agreement with Bank of
America, 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 option,
Eurodollar Rates plus a margin of 2.5% or 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 provides that a
change of control of the Company (as defined in the Credit Facility) will
constitute an event of default.

         The Credit Facility contains a number of financial covenants that
require the Company to meet certain ratios and tests and also provides that a
change of control of the Company (as defined in the Credit Facility) will
constitute an event of default. As of the quarter ended October 1, 1999, the
Company was not in compliance with certain of these covenants. The Company
recently obtained a waiver from the bank for violations of the financial
covenants and the covenants have been amended for future periods.

         The Company anticipates that its principal use of cash during 1999 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, will be adequate to meet its anticipated
requirements for the foreseeable future for working capital, capital
expenditures and interest payments.

YEAR 2000 ISSUE

         GENERAL DESCRIPTION OF THE YEAR 2000 ISSUE AND THE NATURE AND EFFECTS
OF THE YEAR 2000 ON INFORMATION TECHNOLOGY (IT) AND NON-IT SYSTEMS

         The Year 2000 issue ("Year 2000 Issue") is the result of computer
programs being written using two digits rather than four to define the
applicable year. Any of the Company's computer programs or hardware that have
date-sensitive software or embedded chips may recognize a date using "00" as the
year 1900 rather than the Year 2000. This could result in a system failure or
miscalculation causing disruptions of operations, including, among other things,
a temporary inability to process transactions, send invoices, or engage in
similar normal business activities.

         Based on its assessments, the Company determined that it had to modify
or replace significant portions of its software and certain hardware so that
those systems will properly utilize dates beyond


                                       11

<PAGE>

December 31, 1999. The Company believes that with modifications or replacements
of existing software and certain hardware, the Year 2000 Issue can be mitigated.

         The Company's plan to resolve the Year 2000 Issue involves the
following three phases: assessment, remediation, and testing. The Company has
fully completed its assessment of all systems that could be significantly
affected by the Year 2000 Issue. The completed assessment indicated that most of
the Company's significant information technology systems could be affected,
particularly the general ledger, billing, and inventory systems. That assessment
also indicated that software and hardware (embedded chips) used in production
and manufacturing systems do not represent significant risks. The Company does
not believe that the Year 2000 presents a material exposure as it relates to the
Company's products.

         STATUS OF PROGRESS IN BECOMING YEAR 2000 COMPLIANT

         With respect to its information technology, the Company is 100%
complete on the remediation phase, with the completion of software and hardware
replacement as of August 28, 1999. Completion of the testing phase for all
significant information technology systems was completed as of September 30,
1999.

         The Company is utilizing both internal and external resources to
replace and test the software and hardware for resolution of the Year 2000
Issue. In conjunction with the Company's current $2.8 million information
technology systems re-engineering effort, approximately 50% of the total cost is
estimated to be related to the Year 2000 project. Most of the cost of the new
system has been funded through a lease.

         NATURE AND LEVEL OF IMPORTANCE OF THIRD PARTIES AND THEIR EXPOSURE TO
THE YEAR 2000 ISSUE

         The Company has no significant systems which would interface directly
with third party vendors. To date, the Company is not aware of any external
agent with a Year 2000 Issue that would materially impact the Company's results
of operations, liquidity, or capital resources. The Company has sent out
questionnaires to external agents during the first quarter of 1999 in an effort
to verify the external agents' Year 2000 readiness. However, the Company has no
means of ensuring that the external agents will be Year 2000 ready. The
inability of external agents to complete their Year 2000 resolution process in a
timely fashion could materially impact the Company. The effect of non-compliance
by external agents is not determinable.

         RISKS AND CONTINGENCY PLAN

         Management believes it has mitigated the Year 2000 Issue and it has not
developed a contingency plan. However, it is possible that disruptions to the
economy resulting from the Year 2000 Issue could adversely affect the Company.
The amount of potential liability and lost revenue cannot be reasonably
estimated at this time.

ITEM 3.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

         As reported by the Company in its Annual Report on Form 10-K for the
fiscal year ended January 1, 1999, the Company is exposed to market risks
related to fluctuations in interest rates on its $110 million aggregate
principal amount of fixed interest rate senior notes due 2007 ("Senior Notes")
and its $30 million aggregate principal amount of floating interest rate notes
due 2007 ("Floating-Rate Notes"). The Company does not currently use interest
rate swaps or other types of derivative financial instruments.

         For fixed rate debt such as the Senior Notes, changes in interest rates
generally affect the fair value of the debt instrument. For variable rate debt
such as the Floating-Rate Notes, changes in interest rates generally do not
affect the fair value of the debt instrument, but do affect earnings and cash
flows. The Company does not have an obligation to repay its Senior Notes prior
to maturity in 2007 and, as a result, interest rate risk and changes in fair
value should not have a significant impact on the Company. Management believes
that the interest rate on the Senior Notes approximates the current rates
available for similar types of financing and as a result the carrying amount of
the Senior Notes approximates fair value. The carrying value of the
Floating-Rate Notes approximates fair value as the interest rate is variable and
resets frequently. The Floating-Rate Notes bear interest at a rate per annum
equal to LIBOR plus 400 basis points and each one percentage point increase in
interest rates would result in an increase in interest expense of $300,000 per
year.

         Management does not believe that the future market rate risk related to
the Senior Notes and Floating-Rate Notes will have a material impact on the
Company's financial position, results of operations or liquidity.
