                           CORE MATERIALS CORPORATION
                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.  PRESENTATION

         The accompanying unaudited financial statements have been prepared in
accordance with the instructions to Form 10Q and include all of the information
and disclosures required by accounting principles generally accepted in the
United States of America for interim reporting, which are less than those
required for annual reporting. In the opinion of management, the accompanying
unaudited financial statements contain all adjustments (all of which are normal
and recurring in nature) necessary to present fairly the financial position of
Core Materials Corporation ("Core Materials") at June 30, 2001, and the results
of operations and cash flows. The "Notes to Financial Statements", which are
contained in the 2000 Annual Report to shareholders, should be read in
conjunction with these Financial Statements. Certain reclassifications have been
made to prior year's amounts to conform to the classifications of such amounts
for 2001.

         Core Materials operates in the plastics market, specifically in the
production of high quality compression Sheet Molding Composite ("SMC")
fiberglass reinforced plastics. Core Materials produces and sells both SMC
compound and molded products for varied markets including the automotive and
trucking industries and recreational vehicles.


2. EARNINGS PER COMMON SHARE

          Basic earnings per common share are computed based on the weighted
average number of common shares outstanding during the period. Diluted earnings
per common share are computed similarly but include the effect of the exercise
of stock options under the treasury stock method. In calculating net income per
share for the three and six months ended June 30, 2001 and 2000, stock options
had no effect on the weighted average shares for the computation of diluted
income per share and consequently basic and diluted net income per share were

         When Core Materials Corporation enters into variable rate obligations
or purchases variable rate interest bearing assets, it considers the potential
effect of interest rate fluctuations on such instruments. In order to minimize
the effects of interest rate fluctuations on its operations, the Company may
enter into interest rate management arrangements.

         In conjunction with its variable rate Industrial Revenue Bond, Core
Materials entered into an interest rate swap agreement, which was designated as
a cash flow hedging instrument, with a commercial bank in June 1998. Under this
agreement, Core Materials pays a fixed rate of 4.89% to the bank and receives
76% of the 30-day commercial paper rate. The difference paid or received varies
as short-term interest rates change and is accrued and recognized as an
adjustment to interest expense. The swap term matches the payment schedule on
the IRB with final maturity in April 2013. While Core Materials is exposed to
credit loss on its interest rate swap in the event of non-performance by the
counterparty to the swap, management believes such non-performance is unlikely
to occur given the financial resources of the counterparty. The effectiveness of
the swap is assessed at each financial reporting date by comparing the
commercial paper rate of the swap to the benchmark rate underlying the variable
rate of the Industrial Revenue Bond.

         The Company adopted Statement of Financial Accounting Standards (SFAS)
No. 133, Accounting for Derivative Instruments and Hedging Activities, on
January 1, 2001. At January 1, 2001, the Company recorded the fair value of its
interest rate swap agreement of $159,000 as a long-term liability and $105,000
(net of deferred income tax benefit of $54,000) to accumulated other
comprehensive income (loss).

4. COMPREHENSIVE INCOME (LOSS)

         Comprehensive income (loss) represents net income (loss) plus the
results of certain non-shareowners' equity changes not reflected in the
Statement of Income. The components of comprehensive income (loss), net of tax,
are as follows:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

         Certain statements under this caption constitute "forward-looking
statements" which involve certain risks and uncertainties. Core Materials'
actual results may differ significantly from those discussed in the
forward-looking statements. Factors that may cause such a difference include,
but are not limited to: business conditions in the plastics, transportation,
recreation and consumer products industries, the general economy, competitive
factors, the dependence on three major customers, the recent efforts of Core
Materials to expand its customer base, new technologies, regulatory
requirements, labor relations, the loss or inability to attract key personnel,
the availability of capital and management's decisions to pursue new products or
businesses which involve additional costs, risks or capital expenditures.

                                    OVERVIEW

         On December 31, 1996, Core Materials acquired substantially all of the
assets and assumed certain liabilities of Columbus Plastics, a wholly owned
operating unit of International's truck manufacturing division since its
formation in late 1980.

         Core Materials manufactures high quality compression SMC fiberglass
reinforced parts. The demand for Core Materials' products is affected by
economic conditions in the United States and Canada. Core Materials'
manufacturing operations have a significant fixed cost component. Accordingly,
during periods of changing demands, the profitability of Core Materials'
operations may change proportionately more than revenues from operations.

         At the time of the acquisition of Columbus Plastics, International and
Core Materials entered into a Comprehensive Supply Agreement, which expires on
December 31, 2001. Under the terms of the Comprehensive Supply Agreement, Core
Materials became the primary supplier of International's original equipment and
service requirements for fiberglass reinforced parts using the SMC process. At
this time, there are no plans to renew this agreement. If the agreement expires
without an extension, Core Materials will supply products to International on a
purchase order basis, like it operates with all of its other customers. The
purchase orders typically provide volume commitments for four weeks at prices
previously negotiated. Customers can update their orders on a daily basis for
changes in demand that allow them to run their inventories on a "just-in-time"
basis.

RESULTS OF OPERATIONS

    THREE MONTHS ENDED JUNE 30, 2001 AS COMPARED TO THREE MONTHS ENDED JUNE 30,
    2000

    Net sales for the three months ended June 30, 2001, totaled $17,458,000
representing an approximate 25% decrease from the $23,208,000 reported for the
three months ended June 30, 2000. Sales to International decreased to $9,508,000
from $13,897,000 for the three months ended June 30, 2000. The primary reason
for the decrease was lower demand from International resulting from an industry
wide general decline in truck orders. Sales to Yamaha decreased for the three
months ended June 30, 2001 to $3,488,000 compared with $5,000,000 for the three
months ended June 30, 2000. The decrease in Yamaha sales is primarily the result
of lower demand due to the seasonal nature of the personal watercraft industry
and also due to the weaker general economic conditions, which has resulted in
lower sales by Yamaha to end-users.

    Sales to other customers for the three months ended June 30, 2001, increased
4% to $4,463,000 from $4,310,000 for the three months ended June 30, 2000. The
increase was primarily due to sales to Lear Corporation. The Company began
selling product to Lear in the first quarter of 2001, and sales for the three
months ended June 30, 2001, were $2,728,000. The Lear products consist of SMC
components that Lear assembles into seat bottoms and backs for a new sports
utility/pick-up truck recently introduced by an

                                       7
   8

automotive original equipment manufacturer. The Company saw a discontinuance of
its business relationship with Case/New Holland in the second quarter of 2001.
Sales to Case/New Holland totaled $980,000 compared to $2,158,000 for the three
months ended June 30, 2000. Also partially offsetting the gain in sales was the
discontinuance of business in 2000 with Caradon Doors and Windows, Peachtree
Division. For the three months ended June 30, 2000, sales to Caradon were
$762,000. Sales levels were also down to Volvo Trucks North America and other
various customers.

    Gross Margin was 13.8% of sales for the three months ended June 30, 2001,
compared with 14.7% for the three months ended June 30, 2000. The decrease in
gross margin as a percent of sales, from the prior year, is primarily due to
fixed costs associated with excess capacity, production inefficiencies
associated with reduced order flow, and new product start-ups, mostly affecting
the Columbus plant. However, improved productivity and a better product mix
resulted in gross margin improvement in the Gaffney plant compared to last
year.

    Selling, general and administrative expenses ("SG&A") totaled $1,711,000 for
the three months ended June 30, 2001, decreasing from $2,342,000 for the three
months ended June 30, 2000. The decrease from 2000 was due to lower salary and
benefit costs, primarily due to a reduction in personnel, and due to reductions
in supplies, outside services, travel and other expenses resulting from cost
containment activities and declining volumes.

     Interest expense totaled $502,000 for the three months ended June 30, 2001,
increasing from $422,000 for the three months ended June 30, 2000. The increase
in interest expense from 2000 is primarily due to interest expense being reduced
in 2000 by a higher amount of capitalized interest associated with assets being
constructed. Interest income totaled $104,000 for the three months ended June
30, 2001, increasing from $68,000 for the three months ended June 30, 2000 due
to increased funds available for investment.

    Income taxes for the three months ended June 30, 2001, are estimated to be
approximately 41% of total earnings before taxes. Actual tax payments will be
lower than the recorded expenses as Core Materials has substantial federal tax
loss carryforwards. These loss carryforwards were recorded as a deferred tax
asset. As the tax loss carryforwards are utilized to offset federal income tax
payments, Core Materials reduces the deferred tax asset as opposed to recording
a reduction in income tax expense. Projected future income tax payments related
to income earned for the three months ended June 30, 2001, are estimated to be
approximately $49,000 which reflects federal alternative minimum, state and
local taxes.

    Net income for the three months ended June 30, 2001, was $176,000 or $.02
per basic and diluted share, a decrease of $239,000 over the net income for the
three months ended June 30, 2000, of $415,000 or $.04 per basic and diluted
share. The Company has approximately $18 million of operating tax loss
carryforwards that are available to offset income taxes on future earnings.
These tax loss carryforwards do not begin to expire until the year 2007. If the
benefit of the Company's operating tax loss carryforwards were recorded as a
reduction in income tax expense, which is reflective of the actual cash
treatment, net income for the three months ended June 30, 2001, would have been
increased by $75,000, or $.01 per diluted share, to a total of $251,000, or $.03
per diluted share. The comparable 2000 net income would have been increased by
$178,000, or $.02 per diluted share, to a total of $593,000, or $.06 per diluted
share.

    SIX MONTHS ENDED JUNE 30, 2001 AS COMPARED TO SIX MONTHS ENDED JUNE 30, 2000

    Net sales for the six months ended June 30, 2001, totaled $36,558,000
representing an approximate 26% decrease from the $49,120,000 reported for the
six months ended June 30, 2000. Sales to International decreased to $19,494,000
from $31,333,000 for the six months ended June 30, 2000. The primary reason for
the decrease was lower demand from International resulting from an industry wide
general decline in truck orders. Sales to Yamaha decreased slightly for the six
months ended June 30, 2001 to $9,118,000 compared with $9,646,000 for the six
months ended June 30, 2000. The decrease in Yamaha sales is primarily due to the
general economic conditions and its impact on the personal watercraft industry
as noted above.

    Sales to other customers for the six months ended June 30, 2001, decreased
slightly to $7,945,000 from $8,141,000 for the six months ended June 30, 2000.
The decrease in sales was primarily the result of the Company discontinuing its
business relationships with Caradon Doors and Windows, Peachtree Division, and
Case/New Holland as discussed above. Sales to Caradon totaled $1,245,000 for the
six months ended June 30, 2000. Sales to Case/New Holland were $3,170,000 for
the six months ended June 30, 2001, compared to $4,257,000 for the same period
in 2000. Also contributing to the decrease were declines in sales to Volvo
Trucks North America and other various customers. Partially offsetting these
amounts was new business with Lear Corporation, which totaled $3,054,000 in
sales for the six months ended June 30, 2001.

                                       8
   9
    Gross margin was 13.2% of sales for the six months ended June 30, 2001,
compared with 16.0% for the six months ended June 30, 2000. The decline in gross
margin percentage is primarily due to the reasons noted above. Additionally, the
Company experienced higher energy costs resulting from an increase in natural
gas prices.

    SG&A totaled $3,738,000 for the six months ended June 30, 2001, decreasing
from $5,017,000 for the six months ended June 30, 2000. The decrease from the
2000 amount is primarily due to the reasons noted above for the three months.

    Income taxes for the six months ended June 30, 2001, are estimated to be
approximately 41% of total earnings before taxes. Actual tax payments will be
lower than the recorded expenses as Core Materials has substantial federal tax
loss carryforwards. These loss carryforwards were recorded as a deferred tax
asset. As the tax loss carryforwards are utilized to offset federal income tax
payments, Core Materials reduces the deferred tax asset as opposed to recording
a reduction in income tax expense. Projected future income tax payments related
to income earned for the six months ended June 30, 2001, are estimated to be
approximately $50,000 which reflects federal alternative minimum, state and
local taxes.

    Net income for the six months ended June 30, 2001, was $179,000 or $.02 per
basic and diluted share, a decrease of $1,058,000 compared to the net income for
the six months ended June 30, 2000, of $1,237,000 or $.13 per basic and diluted
share. The Company has approximately $18 million of operating tax loss
carryforwards that are available to offset income taxes on future earnings.
These tax loss carryforwards do not begin to expire until the year 2007. If the
benefit of the Company's operating tax loss carryforwards were recorded as a
reduction in income tax expense, which is reflective of the actual cash
treatment, net income for the six months ended June 30, 2001, would have been
increased by $76,000, or $.01 per diluted share, to a total of $255,000, or $.03
per diluted share. The comparable 2000 net income would have been increased by
$529,000, or $.05 per diluted share, to a total of $1,766,000, or $.18 per
diluted share.

LIQUIDITY AND CAPITAL RESOURCES

         Core Materials' primary cash requirements are for operating expenses
and capital expenditures. These cash requirements have historically been met
through a combination of cash flow from operations, equipment leasing, issuance
of Industrial Revenue Bonds and bank lines of credit.

         Cash provided by operations for the six months ended June 30, 2001,
totaled $5,733,000. Net income contributed $179,000 with depreciation and
amortization adding another $1,073,000. Adding positive operating cash flows was
an increase in accounts payable of $2,971,000, primarily related to timing
effects. Also increasing cash flows was a decrease in prepaid and other assets
of $1,710,000 due to the collection of the outstanding receivable relating to
the sale-leaseback transaction, which occurred at the end of 2000. In addition,
accrued and other liabilities added $955,000 in positive cash flow, which was
primarily due to an increase in the accrual for interest charges on the
long-term debt to International. Decreasing the operating cash flow was an
increase in accounts receivable of $932,000, which was primarily due to new
business started with Lear Corporation. Also decreasing operating cash flows was
an increase in inventory of $318,000 due to production for Lear Corporation
reaching full volumes.

         Investing activities negatively affected cash flow by $643,000 for the
six months ended June 30, 2001. Capital expenditures totaled $923,000 primarily
related to the acquisition of machinery and equipment. Offsetting these
expenditures were proceeds from maturities on Core Materials' mortgage-backed
security investment of $260,000.

         Financing activities reduced cash flow by $160,000 due to principal
repayments on the $7,500,000 Industrial Revenue Bond that was issued in 1998.

         At June 30, 2001, Core Materials had cash on hand of $7,642,000 and an
available line of credit of $7,500,000. As of June 30, 2001, Core Materials was
in compliance with all three of its financial debt covenants for its line of
credit, its letter of credit securing the industrial revenue bond and certain
equipment leases. The covenants relate to maintaining certain financial ratios.
Management expects Core Materials to remain in compliance for the remainder of
2001. However, if a material adverse change in the financial

                                       9
   10

position of the Company should occur, Core Materials' liquidity and ability to
obtain further financing to fund future operating and capital requirements could
be negatively impacted.

NEW ACCOUNTING PRONOUNCEMENTS

         In July 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 141, "Business Combinations," to establish
accounting and reporting requirements for business combinations. Previously, the
purchase method or the pooling method of accounting for business combinations
was acceptable depending on certain criteria being met or not. This new standard
requires the use of the purchase method of accounting for all business
combinations. This statement is effective for the Company beginning June 20,
2001. The Company is currently assessing the impact of SFAS No. 141, and the
Company does not anticipate this statement to have a material effect on its
results of operations and its financial position.

         Also in July 2001, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets". This statement applies to intangibles and goodwill acquired
after June 30, 2001, as well as goodwill and intangibles previously acquired.
Under this statement, goodwill, as well as other intangibles determined to have
an infinite life, will no longer be amortized; however, these assets will be
reviewed for impairment on a periodic basis. This statement is effective for the
Company for the fiscal year beginning after December 15, 2001. The Company is
currently assessing the impact of SFAS No. 142, and the Company does not
anticipate this statement to have a material effect on its results of operations
and its financial position.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Core Materials' primary market risk results from fluctuations in
interest rates. Core Materials is also exposed to changes in the price of
commodities used in its manufacturing operations. The Company does not hold any
material market risk sensitive instruments for trading purposes.

         Core Materials has the following four items that are sensitive to a
change in interest rates: (1) Long-term debt consisting of an Industrial Revenue
Bond ("IRB") with a balance at June 30, 2001, of $6,620,000. Interest is
variable and is computed weekly; the average interest rate charged for the six
months ended June 30, 2001, was 3.63%, and the maximum interest rate that may be
charged at any time over the life of the IRB is 10%. In order to minimize the
effect of the interest rate fluctuation, Core Materials has entered into an
interest rate swap arrangement under which Core Materials pays a fixed rate of
4.89% to a bank and receives 76% of the 30 day commercial paper rate; (2)
Long-term Secured Note Payable with a balance as of June 30, 2001, of
$19,920,000 at a fixed interest rate of 8%; (3) 7% mortgage-backed security
which matures in November 2025. Such security is recorded at cost and is
considered held to maturity as Core Materials has the intent and ability to hold
such security to maturity; and (4) Revolving line of credit, which bears
interest at LIBOR plus three and one-quarter percent or prime plus one-quarter
percent as elected by Core Materials.

         Assuming a hypothetical 20% change in short-term interest rates in both
the six month period ended June 30, 2001 and 2000, interest expense would not
change significantly, as the interest rate swap agreement would generally offset
the impact.
