CLARCOR Inc.
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
(Dollars in thousands, except per share data)
(Unaudited)

1.   CONSOLIDATED FINANCIAL STATEMENTS

     The November 30, 2003 consolidated balance sheet data was derived from
     CLARCOR's year-end audited financial statements, but does not include all
     disclosures required by accounting principles generally accepted in the
     United States of America. Certain information and footnote disclosures
     normally included in financial statements prepared in accordance with
     accounting principles generally accepted in the United States of America
     have been condensed or omitted.

     The consolidated condensed balance sheet as of February 28, 2004, the
     consolidated condensed statements of earnings and the consolidated
     condensed statements of cash flows for the periods ended February 28, 2004,
     and March 1, 2003, have been prepared by the Company without audit. The
     financial statements have been prepared on the same basis as those in the
     Company's November 30, 2003 annual report on Form 10-K. In the opinion of
     management, all adjustments (which include only normal recurring
     adjustments) necessary to present fairly the financial position, results of
     operations, and cash flows have been made. The results of operations for
     the period ended February 28, 2004 are not necessarily indicative of the
     operating results for the full year. Certain reclassifications have been
     made to conform prior years' data to the current presentation. These
     reclassifications had no effect on reported earnings.

2.   STOCK-BASED COMPENSATION

     The Company accounts for stock-based compensation using the intrinsic value
     method. If the Company had determined compensation expense for its
     stock-based compensation plans based on the fair value at the grant dates,
     the Company's pro forma net earnings and basic and diluted earnings per
     share (EPS) would have been as follows:

</TABLE>

5.   RELOCATION COSTS

     On January 8, 2004, the Company announced that the corporate headquarters
     will move to Nashville, TN in 2004. Costs for this move, which will largely
     be a one-time expense incurred primarily during the third quarter of fiscal
     2004, are still being finalized. Approximately $8 was accrued during the
     first quarter ended February 28, 2004 for employee termination benefits.
     These termination benefits, currently estimated at $100, are dependent upon
     the employees rendering service through the retention period and will be
     recognized ratably over the required service period. Relocation costs in
     total are not expected to exceed $0.07 per share. The Company expects to
     pay all significant relocation costs during fiscal year 2004.

6.   GUARANTEES AND WARRANTIES

     The Company has provided letters of credit totaling approximately $23,513
     to various government agencies, primarily related to industrial revenue
     bonds and to insurance companies

     and other entities in support of its obligations. The Company believes that
     no payments will be required resulting from these accommodation
     obligations.

     In the ordinary course of business, the Company also provides routine
     indemnifications and other guarantees whose terms range in duration and
     often are not explicitly defined. The Company does not believe these will
     have a material impact on the results of operations or financial condition
     of the Company.

     The Company has a majority ownership interest in a consolidated affiliate
     in which the Company has agreed, under certain conditions, to buy out the
     minority owners' interest for an amount estimated not to exceed $850.

     Warranties are recorded as a liability on the balance sheet and as charges
     to current expense for estimated normal warranty costs and, if applicable,
     for specific performance issues known to exist on products already sold.
     The expenses estimated to be incurred are provided at the time of sale and
     adjusted as needed, based primarily upon experience.

     Changes in the Company's warranty accrual during the quarter ended February
     28, 2004 are as follows:

     Amortization expense is estimated to be $759 in 2004, $755 in 2005, $721 in
     2006, $708 in 2007, and $653 in 2008.

8.   CONTINGENCIES

     The Company is involved in legal actions arising in the normal course of
     business. Additionally, the Company is party to various proceedings
     relating to environmental issues. The U.S. Environmental Protection Agency
     (EPA) and/or other responsible state agencies have designated the Company
     as a potentially responsible party (PRP), along with other companies, in
     remedial activities for the cleanup of waste sites under the federal
     Superfund statute.

     Although it is not certain what future environmental claims, if any, may be
     asserted, the Company currently believes that its potential liability for
     known environmental matters does not exceed its present accrual of $50.
     However, environmental and related remediation costs are difficult to
     quantify for a number of reasons, including the number of parties involved,
     the difficulty in determining the extent of the contamination, the length
     of time remediation may require, the complexity of the environmental
     regulation and the continuing advancement of remediation technology.
     Applicable federal law may impose joint and several liability on each PRP
     for the cleanup.

     It is the opinion of management, after consultation with legal counsel that
     additional liabilities, if any, resulting from these legal or environmental
     issues, are not expected to have a material adverse effect on the Company's
     financial condition or consolidated results of operations.

     In the event of a change in control of the Company, termination benefits
     may be required for certain executive officers and other key employees.

10.  NEW ACCOUNTING STANDARDS

     Effective January 12, 2004, the FASB issued FASB Staff Position No. 106-1,
     "Accounting and Disclosure Requirements Related to the Medicare
     Prescription Drug, Improvement and Modernization Act of 2003," (the Act).
     This Staff Position permits a sponsor of a postretirement health care plan
     that provides a prescription drug benefit to make a one-time election to
     defer accounting for the effects of the Act until authoritative guidance on
     accounting for subsidies provided by the Act is issued. The Act introduces
     a prescription drug benefit under Medicare as well as a federal subsidy to
     sponsors of retiree health care benefit plans. The Company does not
     anticipate that the Act will have a material effect on the measurement of
     the Company's postretirement obligations.

     On December 23, 2003, the FASB issued SFAS No. 132R, "Employers'
     Disclosures about Pensions and Other Postretirement Benefits." This
     Statement requires additional disclosures to be made by employers regarding
     pensions and other postretirement benefit plans, but does not change the
     measurement or recognition of those plans. The interim period disclosure
     requirements of the Statement are effective for interim periods beginning
     after December 15, 2003. The Company will adopt the interim provisions of
     this Statement beginning in the second quarter of 2004. All other
     provisions of this Statement will be adopted in the fourth quarter of 2004.

Part I - Item 2

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS: FIRST QUARTER OF 2004 COMPARED WITH FIRST QUARTER OF
2003.

CLARCOR reported record sales, operating profit and net earnings for the first
quarter of 2004. Sales increased 2.2%, operating profit increased 15.0% and net
earnings increased 21.5% over the same quarter in 2003.

Net sales of $175,272,000 increased from $171,494,000 reported for the first
quarter of 2003. Favorable currency translation, due to the weaker U.S. dollar,
improved sales by approximately $900,000.

The Engine/Mobile Filtration segment reported increased sales of 6.0% to
$70,800,000 from $66,776,000 in 2003. This increase was primarily due to
additional sales of heavy-duty filters through domestic aftermarket and national
account distribution and sales to railroads and railroad equipment maintenance
companies. International sales also increased, both in local currencies and U.S.
dollars. The favorable currency translation due to the weaker U.S. dollar
resulted in additional sales of approximately $400,000 for the quarter.

The Company's Industrial/Environmental Filtration segment recorded a 1.6%
overall decrease in sales to $88,962,000 for the 2004 quarter from $90,369,000
for the 2003 first quarter. The decreased sales level was primarily due to
reduced customer demand for HVAC filters used in building maintenance and for
air quality equipment. Sales increases were recorded for specialty process
liquid filters, both domestically and internationally. Approximately $500,000 of
sales for the quarter was related to favorable currency translation during the
2004 quarter.

The Packaging segment reported sales of $15,510,000 compared to $14,349,000 in
2003. Sales increases for the quarter were related to flat sheet metal
decorating and tooling charges billed to customers; however, these increases
were partially offset by reduced sales of plastic packaging and metal container
sales that were particularly strong in the first quarter of 2003.

Operating profit for the first quarter of 2004 was $17,813,000 compared to
$15,487,000 in 2003, a 15.0% increase. The operating profit increase resulted
primarily from the Engine/Mobile segment's sales growth, from continued cost
reduction programs throughout each of the business segments, and from
restructuring and integration programs in the Industrial/Environmental segment.

The Engine/Mobile Filtration segment recorded an operating profit increase of
13.7% to $14,425,000 from $12,686,000 in 2003. This increase resulted primarily
from sales growth, cost reduction programs and favorable capacity utilization.
The segment's operating margin was 20.4% compared to 19.0% recorded in the first
quarter of 2003.

The Industrial/Environmental Filtration segment reported operating profit of
$3,252,000 in 2004 compared to $2,373,000 in 2003. Although sales were lower
overall for the quarter, cost reduction initiatives and restructuring and
integration programs benefited the segment's 2004 quarter. In addition,
increased sales of specialty process liquid filters, used primarily in aerospace
and aviation fuel systems, also improved operating profit. The segment's
operating margin improved to 3.7% compared to 2.6% in the 2003 quarter.

<PAGE>

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

           OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, Continued

The Packaging segment's operating profit in the 2004 quarter was $136,000
compared to $428,000 in 2003. The decrease resulted from reduced utilization of
facilities and unfavorable absorption related primarily to reduced plastic
product sales and metal container sales.

Net other income for the quarter of $585,000 included a gain of $720,000 related
to the sale of a building, interest expense of $118,000 and interest income of
$51,000. Net other expense in 2003 of $368,000 included interest expense of
$524,000 and interest income of $110,000. Interest expense was lower in 2004 due
to significantly lower debt balances during the 2004 quarter.

Earnings before income taxes and minority interests for the first quarter of
2004 totaled $18,398,000, compared to $15,119,000 in the comparable quarter last
year. The provision for income taxes in 2004 was $6,703,000 compared to
$5,516,000 in 2003. The effective rate was 36.4% in 2004 and 36.5% in 2003. The
Company expects that the overall effective tax rate for fiscal 2004 will be
approximately 36.5%.

Net earnings in the first quarter of the current year were $11,661,000, or $0.45
per share on a diluted basis. Net earnings in the first quarter of 2003 were
$9,596,000, or $0.38 per share on a diluted basis. Diluted average shares
outstanding were 25,813,606 at the end of the first quarter of 2004, an increase
of 1.8% from the average of 25,348,353 for the 2003 quarter.

LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities increased to $14,807,000 in first quarter
2004 compared to $13,218,000 in 2003, primarily due to increased net earnings.
In the first quarter of 2004, cash flows for investing activities totaled
$3,835,000 and included $5,242,000 used for plant asset additions offset by
$1,407,000 received from the sale of plant assets. In the 2003 quarter,
$3,017,000 was used for additions to plant assets. Cash flows used in financing
activities totaled $1,412,000 in 2004 and included $3,175,000 used for dividend
payments offset by $1,500,000 that was drawn on a line of credit. Cash flows
used in financing activities of $15,154,000 in 2003 included net repayments on
debt agreements of $12,264,000 and dividend payments of $3,052,000.

CLARCOR's current operations continue to generate cash and sufficient lines of
credit remain available to fund current operating needs, pay dividends, fund
planned capital expenditures, and provide for interest payments and required
principal payments related to the Company's debt agreements. At the end of the
first quarter of 2004, $1,500,000 was the outstanding balance on a $165 million
multicurrency revolving credit facility. The credit facility also includes a $40
million letter of credit line subline, against which $14,132,000 had been issued
at the end of the first quarter of 2004. Other long-term debt totaled
$17,553,000 at the end of the 2004 quarter and related principal payments in
2004 will be approximately $674,000. The Company is in compliance with all
covenants related to debt agreements.

The Company expects to continue to use future additional cash flow for
dividends, capital expenditures and acquisitions. Capital expenditures in fiscal
year 2004 are expected to be approximately $25 million to $30 million and will
be used primarily for normal facility improvements, productivity improvements,
improvements to technical centers, and to support new products. Early in the
second quarter of 2004, the Company acquired the operating assets of a small
engine filter company in England for approximately $5 million, subject to
finalization of assets acquired.

Off-Balance Sheet Arrangements - The Company's off-balance sheet arrangements
relate to various operating leases. Commitments for noncancelable leases in 2004
total approximately $8,229,000. The Company had no derivative, swap, hedge,
variable interest entity or special purpose entity agreements during 2004 or in
fiscal 2003.

The following table summarizes the Company's fixed cash obligations for the
various future years ending November 30:

</TABLE>

While changes in customer demand for the Company's products will affect
operating cash flow, the Company is not aware of any known trends, demands or
reasonably likely events that would materially affect cash flow from operations
in the future. It is likely that cash flow from operations for fiscal 2004 will
be lower than the prior fiscal year due to additional investments in working
capital that may be required to support increased operations in fiscal 2004. In
addition, a higher level of capital expenditures is expected in fiscal 2004 than
in the prior year. It is possible that business acquisitions or dispositions
could be made in the future that may affect operating cash flows and may require
changes in the Company's debt and capitalization.

The Company's financial position at the end of the first quarter reflected cash
and short-term investments of $18,150,000, an increase from $8,348,000 at
year-end 2003. As mentioned previously, subsequent to the end of the first
quarter, approximately $5 million of cash was used for a small asset
acquisition. At the end of the first quarter 2004 compared to year-end 2003,
accounts receivable were reduced by $4,394,000 primarily due to lower sales in
the first quarter of 2004 compared to the fourth quarter of 2003. Inventories
increased $3,958,000 from the year-end level due to inventory requirements for
increased shipments expected for the remainder of 2004. The changes in accounts
receivable and inventories at the end of the first quarter were consistent with
the normal seasonality changes between fiscal quarters. The current ratio at the
end of the first quarter was 2.5 compared to 2.3 at the end of fiscal 2003. The
ratio of total debt to total capitalization was 4.8% at the end of the 2004
first quarter compared to the year-end 2003 level of 4.5%. At the end of the
first quarter 2004, CLARCOR had 25,372,273 shares of common stock outstanding.

OTHER MATTERS

Market Risk

The Company's interest expense on long-term debt is sensitive to changes in
interest rates. In addition, changes in foreign currency exchange rates may
affect assets, liabilities and commitments that are to be settled in cash and
are denominated in foreign currencies. Market risks are also discussed in the
Company's Annual Report and Form 10-K for the year ended November 30, 2003 (the
"Annual Report") in the Financial Review on page 10.

Critical Accounting Policies

The Company's critical accounting policies, including the assumptions and
judgments underlying them, are disclosed in the Company's Annual Report in the
Financial Review on page 10 and in the Notes to the Consolidated Financial
Statements on pages 16-24 and in the Notes to the Consolidated Condensed
Financial Statements included herein. These policies have been consistently
applied in all material respects and address such matters as revenue
recognition, depreciation methods, inventory valuation, asset impairment
recognition, business combination accounting and pension and postretirement
benefits. While the estimates and judgments associated with the application of
these policies may be affected by different assumptions or conditions, the
Company believes the estimates and judgments associated with the reported
amounts are appropriate in the circumstances.

Recent Accounting Pronouncements

Effective January 12, 2004, the FASB issued FASB Staff Position No. 106-1,
"Accounting and Disclosure Requirements Related to the Medicare Prescription
Drug, Improvement and Modernization Act of 2003," (the Act). This Staff Position
permits a sponsor of a postretirement health care plan that provides a
prescription drug benefit to make a one-time election to defer accounting for
the effects of the Act until authoritative guidance on accounting for subsidies
provided by the Act is issued. The Act introduces a prescription drug benefit
under Medicare as well as a federal subsidy to sponsors of retiree health care
benefit plans. The Company does not anticipate that the Act will have a material
effect on the measurement of the Company's postretirement obligations.

On December 23, 2003, the FASB issued SFAS No. 132R, "Employers' Disclosures
about Pensions and Other Postretirement Benefits." This Statement requires
additional disclosures to be made by employers regarding pensions and other
postretirement benefit plans, but does not change the measurement or recognition
of those plans. The interim period disclosure requirements of the Statement are
effective for interim periods beginning after December 15, 2003. The Company
will adopt the interim provisions of this Statement beginning in the second
quarter of 2004. All other provisions of this Statement will be adopted in the
fourth quarter of 2004.

Outlook

Stronger sales growth for the Company overall is expected for the remainder of
2004. Continued sales growth is expected for the Engine/Mobile segment as a
result of continued improvement in aftermarket distribution, increased sales to
OEM dealers and sales of new products. Sales are expected to increase for the
Industrial/Environmental segment as the economy improves and additional facility
maintenance occurs. The Total Filtration Program is also expected to benefit
from the completion of the conversion of a group of 20 company-owned branches
from selling primarily HVAC filtration products to selling the Company's entire
range of liquid and air filter products. Sales and operating profit growth are
expected for the Packaging segment for 2004.

As a result of the anticipated overall sales growth for the Company combined
with continued cost control efforts for the remainder of the year, it is
expected that diluted earnings per share for 2004 will be in the $2.25 to $2.40
range. This range does not include estimated costs of approximately

$0.07 per share related to moving the Company's headquarters to Nashville, TN.
The majority of these costs are expected to be incurred and paid during the
third quarter of fiscal 2004.

Continued emphasis on cost reductions and price changes within each business
unit are expected to offset costs that have recently been increasing for energy
and for purchased materials, primarily metal products. These costs for the
Company may change significantly based on future changes in the U.S. and world
economies. Capital investments will continue to be made in each segment's
facilities to improve productivity and to support new products. While the
Company fully anticipates that sales and profits will improve as a result of
sales initiatives and cost reductions, the Company has developed contingency
plans to reduce discretionary spending if unfavorable economic conditions
persist.

CLARCOR continues to assess acquisition opportunities, primarily in related
filtration businesses. It is expected that these acquisitions would expand the
Company's market base, distribution coverage and product offerings. The assets
of a small engine filter company were acquired early in the second quarter of
2004. This acquisition will not materially affect operating results for 2004.

FORWARD-LOOKING INFORMATION IS SUBJECT TO RISK AND UNCERTAINTY

Certain statements quoted in the body of this report, and statements in the
"Outlook" section of this report are forward-looking. These statements involve
risk and uncertainty. Actual future results and trends may differ materially
depending on a variety of factors including: the volume and timing of orders
received during the period; the mix of changes in distribution channels through
which the Company's products are sold; the success of the Company's Total
Filtration Program; the timing and acceptance of new products and product
enhancements by the Company or its competitors; changes in pricing, labor
availability and related costs, product life cycles, raw material costs,
insurance, pension, energy costs, and purchasing patterns of distributors and
customers; competitive conditions in the industry; business cycles affecting the
markets in which the Company's products are sold; the effectiveness of plant
conversions, plant expansions and productivity improvement programs; the
management of both growth and acquisitions; the cost of the relocation of the
Company's corporate offices; the cost of compliance with recently enacted
regulatory requirements such as Sarbanes-Oxley Rule Section 404; the fluctuation
in interest rates, primarily LIBOR, which affect the cost of borrowing under its
revolving credit facility; the fluctuation in foreign and U.S. currency exchange
rates; extraordinary events such as litigation, acquisitions or divestitures
including related charges; market disruptions caused by domestic or
international conflicts; and economic conditions generally or in various
geographic areas. All of the foregoing matters are difficult to forecast. The
future results of the Company may fluctuate as a result of these and the other
risk factors detailed from time to time in the Company's Securities and Exchange
Commission reports.

Due to the foregoing items it is possible that in some future quarters the
Company's operating results will be below the expectation of some stock market
analysts and investors. In such event, the price of CLARCOR common stock could
be materially adversely affected.

Part I -  Item 3. Quantitative and Qualitative Disclosure About Market Risk.

          The information required hereunder is set forth on Page 14 of the
          Quarterly Report under the captions "Management's Discussion and
          Analysis - Other Matters - Market Risk."

Part I -  Item 4. Controls and Procedures.

          The Company has established disclosure controls and procedures which
          are designed to ensure that information required to be disclosed in
          reports filed or submitted under the Securities Exchange Act of 1934
          are recorded, processed, summarized, and reported within the time
          periods specified in the Securities and Exchange Commission's rules
          and forms. Norman E. Johnson, Chairman of the Board, President, and
          Chief Executive Officer and Bruce A. Klein, Vice President - Finance
          and Chief Financial Officer, evaluated the effectiveness of the
          Company's disclosure controls and procedures as of February 28, 2004.
          Based on their evaluation, they concluded that the Company's
          disclosure controls and procedures were effective in achieving the
          objectives for which they were designed. No change in the Company's
          internal control over financial reporting occurred during the
          Company's most recent fiscal quarter ended February 28, 2004 that has
          materially affected, or is reasonably likely to materially affect, the
          Company's internal control over financial reporting.
