NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 30, 2000

NOTE A -- MANAGEMENT PLANS AND BASIS OF PRESENTATION

The Company reported a net loss of $9,535,000 and cash on hand decreased
$616,000 for the six months ended December 30, 2000. This compares to a net loss
of $3,774,000 in the six months ended January 1, 2000. Additionally, on February
13, 2001, the Company received waivers from its lenders for certain financial
and other covenants as to which the Company was not in compliance as of November
25, 2000 and December 30, 2000. Because a precondition to the effectiveness of
the February 13, 2001 waivers and amendments (relating to the payment of fees to
the Company's lenders) remained unsatisfied as of February 22, 2001, the lenders
under the Loan Agreement notified the Company that (1) specified defaults had
occurred and continued to occur under the Loan Agreement; (2) any further
advances under the Loan Agreement would only be made in the lenders' discretion;
(3) until further notice, all obligations outstanding under the Loan Agreement
would bear interest at a default rate from February 22, 2001; and (4) the
lenders were reserving all of their rights to assert and exercise remedies with
respect to any default in connection with the Loan Agreement.

In addition to strict compliance with the Loan Agreement, the lenders have
required that the Company provide to the lenders cash flow projections and other
specified information, and engage no later than March 7, 2001 a "crisis manager"
acceptable to the lenders.

As a result of the defaults under the Loan Agreement, the Company has classified
all of its indebtedness as a short-term obligation on the accompanying Balance
Sheet as of December 30, 2000.

As a result of the occurrence of the foregoing events of default, the lenders
under the Company's other credit facilities are not obligated to make additional
advances; are entitled to declare all amounts outstanding under the credit
facilities in default, including accrued interest or other obligations, to be
immediately due and payable; have the right to block payments on substantially
all of the Company's other long-term debt; and are entitled to proceed against
the collateral granted to them to secure the applicable debt. Cross defaults
under all of the Company's credit facilities have been triggered such that
substantially all of the Company's other long-term debt could be declared
immediately due and payable. In this event, the Company may not have sufficient
assets to repay in full all of its long-term debt.

As a result of the operating results and the covenant defaults described above,
the Company's ability to respond to changing business and economic conditions is
significantly restricted and its ability to secure additional financing is
unlikely. Management is unable to conclude that the Company's cash flows from
operations will be adequate to meet its anticipated cash requirements for the
foreseeable future. Management is exploring additional sources of capital and
seeking other accommodations from its lenders and suppliers to aid its
short-term cash requirements. However, there can be no assurance that other
sources of capital will be available or that the Company's lenders and suppliers
will accommodate the Company, or, if such alternate sources of capital are
available or such accommodations are offered, that they will be on terms
acceptable to the Company. If the Company is unable to obtain additional or


                                       6
<PAGE>   7


alternative financing or financial accommodations from its lenders and
suppliers, there can be no assurance that the Company will be able to continue
to meet its cash requirements, which may result in materially adverse
consequences on the Company's business, financial conditions or operations.
Under such circumstances, the Company would be required to substantially reduce
or discontinue its operations, file for bankruptcy or both.

In the fourth quarter of fiscal 1999, the Company began a comprehensive
restructuring of the Company's operations and businesses with a view towards
enhancing and focusing on the Company's operations that are believed to present
the best future profitability and growth potential. As a result of completing
the assessment of various strategic alternatives, the Company concluded that
discontinuing the Company's denim and industrial yarn operations was in the best
interest of the Company. The Company has concluded that it will focus on the
manufacturing and marketing of home furnishings as well as dyeing and finishing
fabrics for casual and career apparel. The Company believes that these
operations offer the most viable opportunity for improving future profitability.
The Company has completed a personnel and operational realignment of these
businesses to improve their future profit margins. Also, at the request of its
lenders, the Company engaged consultants in January of 2001 to provide
consulting services relating to the Company's turnaround and cost reduction
initiatives.

The Company believes that the initiatives discussed above will result in
improved margins and future profitability; however, such plans require
management to make estimates and assumptions regarding future operations. Actual
results could differ from those estimates.

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles applicable
to a going concern that contemplates continuity of operations and realization of
assets and liquidation of liabilities in the normal course of business. As a
result of the Company's debt structure, operating results and current economic
conditions, realization of assets and liquidation of liabilities are subject to
significant uncertainty. These matters, among others, raise substantial doubt
about the Company's ability to continue as a going concern.

Also, the Company's accompanying unaudited condensed consolidated financial
statements have been prepared in accordance with generally accepted accounting
principles for interim financial information and with the instructions to Form
10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included. Operating results for the thirteen and
twenty-six weeks ended December 30, 2000 are not necessarily indicative of the
results that may be expected for the year ending June 30, 2001. Certain fiscal
2000 balances have been reclassified to conform with the fiscal 2001
classifications. For further information, refer to the consolidated financial
statements and footnotes thereto included in the Company's annual report for the
year ended July 1, 2000.

NOTE B -- ACCOUNTING POLICIES ADOPTED IN CURRENT FISCAL YEAR

In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in Financial
Statements. SAB 101 draws upon the existing accounting rules and explains those
rules, by analogy, to other transactions that the existing rules do not
specifically address. SAB 101 is effective for all of the Company's fiscal
quarters of fiscal year 2001.

Financial Accounting Standards Board Statement No. 133, Accounting for
Derivative Instruments and Hedging Activities (SFAS 133), which the Company
adopted effective July 1, 2000, requires companies to recognize all of its
derivative instruments as either assets or liabilities in the statement of
financial position at fair value. The accounting for changes in the fair value
(i.e., gains or losses) of a derivative instrument depends on whether it has
been designated and qualifies as part of a hedging relationship and further, on
the type of hedging relationship. For those derivative instruments that are
designated and qualify as hedging instruments, a company must designate the
hedging instrument, based upon the exposure being hedged, as either a fair value
hedge, cash flow hedge or a hedge of a net investment in a foreign operation.
For derivative instruments not designated as hedging instruments, the gain or
loss is recognized in current earnings during the period of change.

The adoptions of SAB 101, effective October 1, 2000, and SFAS 133, effective
July 1, 2000, did not have a material effect on the Company's financial position
or operating results.

NOTE C -- INVENTORIES

NOTE E  -- SEGMENT INFORMATION

The Company has two reportable segments in its continuing operations: Consumer
Products and Apparel Fabrics. Each reportable segment is organized around
product similarities. The Consumer Products segment manufactures and sells a
complete line of muslin, percale and premium threadcount products for the
bedroom, including fashion-coordinated bedding sets and comforters marketed
under the Thomaston label, and offers home furnishing fabrics for sale to other
manufacturers of home furnishings. The Apparel Fabrics line is directed toward
dyeing and finishing heavier fabrics such as twill and other value-added
fabrics.

The profit performance measure for the Company's segments is defined as Internal
EBIT (earnings before interest and taxes). The aggregate of Internal EBIT for
the reportable segments differs from the Company's consolidated earnings before
interest and taxes by costs that are deemed to be non-operating in nature.

Allocations of corporate general and administrative expenses are used in the
determination of segment profit performance.

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

In the fourth quarter of fiscal 1999, the Company began a comprehensive
restructuring of its operations and businesses with a view towards enhancing and
focusing on the Company's operations which are believed to present the best
future profitability and growth potential. As a result of completing the
assessment of various strategic alternatives, the Company concluded that
discontinuing the Company's denim and industrial yarn operations, which were
unprofitable in recent years, was in the best interest of the Company. In
conjunction with the exit of these businesses, the Company's balance sheet at
December 30, 2000 includes assets held for sale in the amount of $2,684,000. Any
proceeds from the sale of these assets will be applied against outstanding term
loan obligations.

The Company has concluded that it will focus on the manufacturing and marketing
of home furnishings as well as dyeing and finishing fabrics for casual and
career apparel. The Company believes that these operations offer the most viable
opportunity for improving future profitability. The Company completed a
personnel and operational realignment of these businesses which it believes will
improve their future profit margins.

RESULTS OF OPERATIONS

Sales from continuing operations for the second fiscal quarter ended December
30, 2000 were $37,152,000 compared to sales of $37,195,000 for the second fiscal
quarter last year. For the twenty-six weeks ended December 30, 2000, sales were
down 5.3% to $73,785,000 when compared to sales of $77,919,000 for the
twenty-six weeks ended January 1, 2000. Sales in the Consumer Products area of
the Company were up slightly to $49,745,000 compared to sales of $49,308,000 for
the twenty-six weeks ended January 1, 2000. In the Apparel Fabrics area, a shift
in customer demand from heavier, bottom-weight, cotton fabrics to
lighter-weight, blended fabrics resulted in a sales decrease from $28,611,000
for the twenty-six weeks ended January 1, 2000 to $24,040,000 for the twenty-six
weeks ended December 30, 2000.

Cost of sales for the quarter just ended increased to 100.9% of sales or
$37,469,000. For the second quarter fiscal year 2000, cost of sales were 89.7%
of sales or $33,348,000. For the twenty-six weeks ended December 30, 2000, cost
of sales increased to 98.2% of sales or $72,470,000 compared to cost of sales of
89.3% of sales or $69,573,000 for the twenty-six weeks ended January 1, 2000.
During the twenty-six weeks ended December 30, 2000, the Company selectively
idled certain manufacturing facilities in order to better match inventory levels
with orders. Inventories have been reduced $12,061,000, or 32.4%, during the
twenty-six weeks ended December 30, 2000. However, this slowdown of
manufacturing also resulted in decreased manufacturing capacity utilization and
plant productivity and increased volume related negative operating variances.
Raw material prices have also increased during the twenty-six weeks ended
December 30, 2000 as compared to raw material prices during the twenty-six weeks
ended January 1, 2000.

Gross profit for the twenty-six weeks ended December 30, 2000 was 1.8% of sales
compared to 10.7% of sales for the twenty-six weeks ended January 1, 2000.


                                       11
<PAGE>   12

Selling, general and administrative expenses were 9.1% of sales for the thirteen
weeks and 9.2% of sales for the twenty-six weeks ended December 30, 2000. For
the thirteen weeks and twenty-six weeks ended January 1, 2000, selling, general
and administrative expenses were 10.1% and 10.0% of sales, respectively. The
Company's realignment of its operations has contributed to reductions in certain
selling, general and administrative expenses.

Other income for the quarter and twenty-six weeks ended December 30, 2000 was
$49,000 and $84,000, respectively, compared to $289,000 and $405,000 for the
comparable periods last year. Other income relates to miscellaneous equipment
sales, royalties and interest earned on the Company's short-term investments of
cash.

Interest expense and amortization of credit agreement fees totaled $2,166,000
during second quarter fiscal year 2001 and $4,471,000 for the twenty-six weeks
ended December 30, 2000. For the quarter and twenty-six weeks ended January 1,
2000, interest expense and amortization of credit agreement fees totaled
$2,341,000 and $4,483,000, respectively. This decrease was the result of lower
borrowings under the Company's various credit agreements. Excluding capitalized
leases, total debt at December 30, 2000 was $57,993,000, down $10,555,000 from
total debt at July 1, 2000 of $68,548,000.

Although the Company recorded a pre-tax loss from continuing operations for the
second quarter of fiscal year 2001, an income tax expense of $64,000 was also
recorded during this quarter. This expense is the result of a change in deferred
income taxes valuation allowance. During the twenty-six weeks ended January 1,
2000, the Company did not record an income tax benefit as a result of its
operating loss carry forward position.

For the second quarter fiscal year 2001, the Company sustained a loss from
continuing operations of $5,877,000 or $ .90 per basic and diluted share as
compared to a second quarter fiscal year 2000 loss from continuing operations of
$1,946,000 or $ .30 per basic and diluted share. For the twenty-six weeks ended
December 30, 2000, the Company sustained a loss from continuing operations of
$9,901,000 or $1.52 per basic and diluted share as compared to a loss from
continuing operations of $3,530,000 or $ .54 per basic and diluted share for the
twenty-six weeks ended January 1, 2000.

Discontinued operations income was $366,000 for the twenty-six weeks ended
December 30, 2000 and included curtailment income from the Company's employee
benefit plans. The Company recognized curtailment income of approximately
$518,000 during the first quarter of 2001 that resulted from finalizing the
calculations of the impact of the terminated employees from discontinued
operations upon the benefit plans obligations. For the twenty-six weeks ended
January 1, 2000, discontinued operations loss was $244,000, primarily as a
result of shutdown costs associated with closed facilities.

LIQUIDITY AND CAPITAL RESOURCES

Operating activities provided cash of $11,391,000 during the twenty-six weeks
ended December 30, 2000. During the twenty-six weeks ended January 1, 2000,
operating activities provided cash


                                       12
<PAGE>   13

of $5,404,000. Net cash used in investing activities amounted to $1,243,000
during the first half of fiscal 2001 compared to $689,000 used in the first half
of fiscal 2000. Capital expenditures are closely monitored as a result of the
Company's realignment of its operations. Financing activities used cash of
$10,764,000 during the first half of fiscal year 2001 as a result of net
repayments of indebtedness. During the first half of fiscal year 2000, financing
activities used funds of $4,776,000.

The Company's Loan and Security Agreement (the Loan Agreement) provides for
borrowing as follows:

-        Revolving advances equal to the lesser of $70,000,000 or a specified
         percentage of certain accounts receivable and inventory as defined in
         the Loan Agreement. At December 30, 2000, $27,066,000 was outstanding
         and $1,200,000 was available for borrowing under the revolving advances
         provisions. The revolving advances bear interest at the Reference Rate
         plus 1% or the Euro-dollar Rate plus 3.25%. The revolving advances are
         payable on July 27, 2004, and provide for an early termination penalty
         as specified in the Loan Agreement. The revolving advances are reduced
         by collections made through a lock box arrangement required under the
         terms and conditions of the Loan Agreement.

-        Tranche A Term Loan of $20,000,000 is payable in monthly installments
         of $333,333 through July 27, 2004 and bears interest at the Reference
         Rate plus 1.75% or the Euro-dollar Rate plus 3.75%.

-        Tranche B Term Loan of $5,000,000 is due July 27, 2004 and bears
         interest at 18.5% of which 15% is payable currently and 3.5% per annum
         is payable on the maturity date.

Borrowings under this Loan Agreement were used to reduce the existing Credit and
Security Agreement to $15,000,000 as discussed below and to repay the senior
notes payable and industrial revenue bonds.

On July 27, 1999, the Company entered into an Amended and Restated Credit and
Security Agreement (the Credit Agreement) which reduced the existing borrowings
to $15,000,000. Interest is accrued at a rate of 15% increasing at the rate of
1% per month to a rate of 20% effective January 1, 2000. Interest is payable
monthly at the Euro-dollar Rate plus 3.5% or the Base Rate plus 1.5%. The
difference in the interest accrued and the interest paid is added to the balance
of the borrowings. Borrowings under the Credit Agreement are due July 27, 2004
unless repaid prior to that date.

On May 31, 2000, the Company entered into a Promissory Note with a bank in the
amount of $10,000,000. Interest is paid monthly at a rate equal to the Prime
Rate plus 1.5%. Borrowings under the Promissory Note are payable monthly
beginning July 1, 2000 through May 31, 2020, unless repaid prior to that date.
Borrowings under this Promissory Note were used to reduce the amount outstanding
under the Credit Agreement by $9,043,000 and to repay $525,000 of the balance
outstanding under the Loan Agreement.


                                       13
<PAGE>   14

Borrowings under the Loan Agreement and Credit Agreement and Promissory Note are
secured by all assets and properties of the Company. The Loan Agreement, the
Credit Agreement and the Promissory Note contain various restrictions relating
to, among other things, maintaining a certain level of tangible net worth, a
minimum current ratio, a minimum debt to equity ratio, attainment of certain
amounts of earnings before interest, taxes, depreciation and amortization and
restrictions on capital expenditures.

The Company paid a portion of its real property tax obligations due on December
27, 2000. As a result, the Company is subject to interest on the unpaid amount
of these real property taxes. In addition to interest charges, any property
taxes remaining unpaid after March 27, 2001, will be subject to a late payment
penalty. If the Company does not pay in full its real property tax obligations,
the Company's applicable real properties may become encumbered by tax liens.

At the request of its lenders, the Company engaged in January of 2001 the firm
of Arthur Andersen to provide consulting services relating to the Company's
turnaround and cost reduction initiatives. Arthur Andersen has reported its
findings and recommendations to the Company's management, and at a recent
meeting of the board of directors, the Company's directors decided to
implement some of these recommendations by accepting the resignations of Neil
H. Hightower, President and Chief Executive Officer of the Company, George H.
Hightower, Jr., Executive Vice President and President of the Apparel Fabrics
Division, and H. Stewart Davis, Executive Vice President and President of the
Consumer Products Division. The board also elected A. William Ott as the acting
President and Chief Executive Officer of the Company. Mr. Hightower, Mr.
Hightower, Jr. and Mr. Davis continue to serve as directors of the Company. The
Company's management is studying other recommendations contained in Arthur
Andersen's report in the context of the Company's default on its credit
facilities and its discussions with its lenders.

DEFAULTS ON CREDIT FACILITIES

On February 13, 2001, the Company received waivers executed by its lenders
relating to certain financial and other covenants as to which the Company was
not in compliance as of December 30, 2000. Because a precondition to the
effectiveness of the February 13, 2001 waivers and amendments (relating to the
payment of fees to the Company's lenders) remained unsatisfied as of February
22, 2001, the lenders under the Loan Agreement notified the Company that (1)
specified defaults had occurred and continued to occur under the Loan Agreement;
(2) any further advances under the Loan Agreement would only be made in the
lenders' discretion; (3) until further notice, all obligations outstanding under
the Loan Agreement would bear interest at a default rate from February 22, 2001;
and (4) the lenders were reserving all of their rights to assert and exercise
remedies with respect to any default in connection with the Loan Agreement.

In addition to strict compliance with the Loan Agreement, the lenders have
required that the Company provide to the lenders cash flow projections and other
specified information, and engage no later than March 7, 2001 a "crisis manager"
acceptable to the lenders.

As a result of the defaults under the Loan Agreement, the Company has classified
all of its indebtedness as a short-term obligation on the Company's balance
sheet as of December 30, 2000.

As a result of the occurrence of the foregoing events of default, the lenders
under the Company's other credit facilities are not obligated to make additional
advances; are entitled to declare all amounts outstanding under the credit
facilities in default, including accrued interest or other obligations, to be
immediately due and payable; have the right to block payments on substantially
all of the Company's other long-term debt; and are entitled to proceed against
the collateral granted to them to secure the applicable debt. Cross defaults
under all of the


                                       14
<PAGE>   15

Company's credit facilities have been triggered such that substantially all of
the Company's other long-term debt could be declared immediately due and
payable. In this event, the Company may not have sufficient assets to repay in
full all of its long-term debt.

As a result of the defaults described above, the Company's ability to respond to
changing business and economic conditions and to secure additional financing is
unlikely. Management is unable to conclude that the Company's cash flow from
operations will be adequate to meet its anticipated cash requirements for the
foreseeable future. Management is exploring additional sources of capital and
seeking other accommodations from its lenders and suppliers to aid its
short-term cash requirements. However, there can be no assurance that other
sources of capital will be available or that the Company's lenders and suppliers
will accommodate the Company, or, if such alternate sources of capital are
available or such accommodations are offered, that they will be on terms
acceptable to the Company. If the Company is unable to obtain additional or
alternative financing or financial accommodations from its lenders and
suppliers, there can be no assurance that the Company will be able to continue
to meet its cash requirements, which may result in materially adverse
consequences on the Company's business, financial conditions or operations.
Under such circumstances, the Company would be required to substantially reduce
or discontinue its operations, file for bankruptcy or both.

WARRANTS TO LENDERS

As previously disclosed, the Company has issued warrants to its lenders in
connection with the Credit Agreement. The warrants permit the lenders to
purchase Class A and Class B common shares of the Company for nominal
consideration. The warrants are currently exercisable and may be exercised
through December 31, 2004. Although the lenders have not indicated to the
Company that they intend to exercise the warrants, if they elect to exercise all
of their warrants, the lenders would receive an interest equal to 10% of the
outstanding equity of the Company in each class, on a fully diluted basis.

ASSETS HELD FOR SALE

The Company's management intends to utilize the proceeds from the sale of the
assets held for sale to reduce outstanding term loan obligations. Management
believes, based on current appraisals, that $3,835,000 could be realized from
the sale of these assets, including $2,684,000 from the assets related to
discontinued operations. However, actual results could differ significantly from
these estimates. During the twenty-six weeks ended December 30, 2000, the
Company sold $1,596,000 of assets held for sale and used the proceeds to reduce
outstanding term loan obligations.

INVENTORIES

Inventories at December 30, 2000 and July 1, 2000 were $25,175,000 and
$37,236,000, respectively. Improvements in supply-chain inventory control
systems, the selective idling of certain manufacturing facilities and the
selling off of inventories associated with discontinued operations have resulted
in decreased inventory levels at December 30, 2000 as compared to inventory
levels at July 1, 2000. Total inventory turns on an average annualized rate were
5.7


                                       15
<PAGE>   16

times for the first six months of fiscal 2001 as compared to 3.7 times for the
first six months of fiscal 2000.

RAW MATERIALS

The Company's primary raw material is cotton. As a commodity, cotton is traded
on established markets and periodically experiences price fluctuations. The
Company monitors the cotton market and buys its cotton from brokers. The Company
has not had and does not currently anticipate any difficulty in obtaining
cotton.

In order to assure a continuous supply of cotton, the Company enters into cotton
purchase contracts for several months in advance of delivery which either
provide for (1) fixed quantities to be purchased at a pre-determined price or
(2) fixed quantities to be purchased at a price to be determined (at a later
date). When the Company sells its product to its customers, the cost of cotton
under existing cotton purchase contracts is taken into account in calculating
the price for the Company's product. The Company generally attempts to match
product sales contracts with fixed price cotton purchase contracts and uses
market price cotton contracts to anticipate future needs and subsequent product
sales contracts. To the extent prices are sometimes fixed in advance of
shipment, the Company may benefit from its cotton purchase contracts to the
extent prices thereafter rise, or incur increased cost to the extent prices
thereafter fall.

INTERNATIONAL TRADE

In December 1993, 117 countries reached an agreement under the General Agreement
on Tariffs and Trade (GATT) that would cover new areas of trade, further cut
tariffs and strengthen multilateral free-trade rules by creating a World Trade
Organization (WTO) as its successor. This agreement was ratified by the United
States Congress and went into effect on July 1, 1995. As part of this new
agreement, the Multifiber Arrangement (MFA) under which textile and apparel
trade had been controlled, will be phased out along with its import quotas over
a 10-year period. Tariffs on textiles will be cut by an average of 11.6% over 10
years. Under the agreement, the least import-sensitive products are now
quota-free, and from now until 2005, products which will have more of an effect
on the U. S. market will be on the phase-out schedule.

The WTO agreement contains some provisions which may have a favorable impact on
the textile industry. An assembly rule of origin amendment makes it illegal for
a non-WTO member country to assemble garments from pieces cut in a member
country and then export the garments as originating in the country where they
were cut. Additionally, the agreement preserves the authority of the President
of the United States to control imports from non-WTO countries such as Taiwan or
China. China is currently negotiating its membership application with the WTO,
and if the application is accepted and China is admitted to the WTO, the Chinese
market share of apparel imports is expected to increase significantly over the
phase-in period.

Although the WTO agreement may reduce the cost of certain imported textiles, the
Company believes that upgraded technology resulting in increased productivity
and lower costs will enable it to compete in a global market.


                                       16

The recently enacted amendment to the Caribbean Basin Economic Recovery Act
accords, for a specified transition period, the same preferential tariff and
quota treatment given certain textile and apparel articles imported from North
American Free Trade Agreement (NAFTA) countries to such articles that are
imported from certain Caribbean countries. In order to qualify for the
preferential tariff and quota treatment, however, apparel goods that are shipped
back to the United States must be sewn in eligible Caribbean countries using
U.S. yarn and fabrics. The Company believes that this new legislation will allow
it to compete favorably with Asian countries for market share in the apparel
area.

RECENT DEVELOPMENTS

The Company's Class A Common Stock did not maintain the minimum bid price
criteria set forth by the Marketplace Rules of the Nasdaq SmallCap Market (the
"Rules"), and the Company's Class B Common Stock did not maintain the minimum
market value of public float criteria set forth by the Rules. As a result, the
Nasdaq Stock Market ("Nasdaq") delisted the Company's Class A and Class B Common
Stock on December 4, 2000. As a result of the delisting, the Company's shares
are no longer traded on the SmallCap Market, but instead are traded on the
over-the-counter bulletin board system.

Discussion and Analysis of Financial Condition and Results of Operations"
constitute forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. Such forward-looking statements
involve known and unknown risks, uncertainties and other factors which may cause
the actual results, performance or achievements of the Company to be materially
different from any future results, performance or achievements express or
implied by such forward-looking statements. Such factors include, among other
things, business conditions, volatility of commodities markets, ability to
control operating costs, developing successful new products and maintaining

operations that the Company has retained subsequent to its restructuring
efforts. A failure by the Company to obtain capital in the future on terms that

grow, its remaining business lines may have a material adverse effect on the
Company's business, financial condition or results of operations.
