necessary for a fair presentation of the results of the interim periods, have
been made. The results of operations for such interim periods are not
necessarily indicative of the results of operations for a full year. The
Unaudited Condensed Consolidated Financial Statements should be read in
conjunction with the Audited Consolidated Financial Statements and notes thereto
filed with the Company's Annual Report on Form 10-K for the year ended January
31, 2004, which was filed with the Securities and Exchange Commission on April
14, 2004.

     References to a particular year are to the Company's fiscal year, which is
the 52 or 53 week period ending on the Saturday closest to January 31st of the
following calendar year. For example, references to "Fiscal 2003" mean the
fiscal year ending January 31, 2004 and a reference to "Fiscal 2004" is a
reference to the fiscal year ending January 29, 2005. Certain reclassifications
have been made to prior year balances to conform with the current year
presentation.

     On March 9, 2004, the Company announced a three-for-two stock split on all
shares of its common stock that was effected in the form of a stock dividend.
Shareholders' equity has been restated to give retroactive recognition to the
stock split in prior periods and all share and per share amounts have been
restated to give effect to the stock split.

2. STOCK BASED COMPENSATION

     The Company periodically grants stock options to employees. Pursuant to
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees, the Company accounts for stock-based employee compensation
arrangements using the intrinsic value method. Accordingly, no compensation
expense has been recorded in the consolidated financial statements with respect
to option grants. The Company has adopted only the disclosure provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, Accounting for
Stock Based Compensation, as amended by SFAS No. 148, Accounting for Stock Based
Compensation -- Transition and Disclosure, an Amendment of FASB Statement No.
123. If compensation cost for the Company's stock based compensation plans had
been determined in accordance with the fair value method prescribed by SFAS No.
123, the Company's net income would have been:

     The weighted average fair value of the Company's stock options was
calculated using the Black-Scholes Option Pricing Model with the following
weighted average assumptions used for grants in their respective periods. For
the thirteen weeks ended May 1, 2004: no dividend yield; expected volatility of
70%; risk free interest rate of 2.72%; and expected life of 5 years. For the
thirteen weeks ended May 3, 2003: no dividend yield; expected volatility of 70%;
risk free interest rate of 2.81%; and expected life of 4.72 years. There were
480 thousand options granted during the thirteen weeks ended May 1, 2004 with a
weighted average fair value of $6.7 million. There were 744 thousand options
granted during the thirteen weeks ended May 3, 2003 with a weighted average fair
value of $3.9 million.

 NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

4. RECENT ACCOUNTING STANDARDS

     In December 2003, the Financial Accounting Standards Board ("FASB") issued
FAS No. 132 (Revised) ("FAS 132-R"), Employer's Disclosure about Pensions and
Other Postretirement Benefits. FAS 132-R retains disclosure requirements of the
original FAS 132 and requires additional disclosures relating to assets,
obligations, cash flows, and net periodic benefit cost. FAS 132-R is effective
for fiscal years ending after December 15, 2003, except that certain disclosures
are effective for fiscal years ending after June 15, 2004. Interim period
disclosures are effective for interim periods beginning after December 15, 2003.
The adoption of the disclosure provisions of FAS 132-R did not have a material
effect on the Company's condensed consolidated financial statements.

     In March 2004, the FASB published an Exposure Draft, Shares-Based Payment,
an amendment of FASB Statements No. 123 and 95. Under this FASB proposal, all
forms of share-based payment to employees, including employee stock options,
would be treated as compensation and recognized in the income statement. This
proposed statement would be effective for fiscal years beginning after December
15, 2004. The Company currently accounts for stock options under APB No. 25. The
pro-forma impact of expensing options is disclosed in Note 2.

5. EARNINGS PER SHARE

     The following table sets forth the computations of basic and diluted
earnings per share. Basic earnings per share have been computed based upon the
weighted average of common shares outstanding. Diluted earnings per share gives
effect to outstanding stock options.

6. REVOLVING CREDIT FACILITY

     The Amended and Restated Loan and Security agreement allows the Company to
borrow or obtain letters of credit up to an aggregate of $25 million (the
"Credit Facility") with letters of credit having a sub-limit of $15 million. The
Facility matures on September 30, 2005. Indebtedness under the Credit Facility
is collateralized by the assets of the Company. Borrowings under the Credit
Facility bear interest at the Company's option, either at (a) the lender's prime
rate or (b) the Euro Dollar Rate plus 1.25% to 1.75%, dependant upon the
Company's financial performance. Additionally, the Company must pay commitment
fees on any unused portion of the Credit Facility at an annualized rate of
0.375% on the difference between the loan aggregate of $25 million and the
borrowings (including outstanding letters of credit) at the preceding month-end.
There are no covenants in the Credit Facility requiring the Company

to achieve certain earnings levels and there are no capital spending
limitations. There are certain negative covenants under the Credit Facility,
including but not limited to, limitations on the Company's ability to incur
other indebtedness, encumber its assets, or undergo a change of control.
Additionally, the Company is required to maintain a ratio of 2:1 for the value
of the Company's inventory to the amount of the loans under the Credit Facility.
As of May 1, 2004, the Company was in compliance with all covenants under the
Credit Facility. On May 1, 2004 and January 31, 2004, the Company had $0 in
borrowings outstanding under the amended Credit Facility, and no stand-by or
commercial letters of credit had been issued under the facility.

7. RETIREMENT BENEFIT PLANS

     The Company has a qualified, defined benefit retirement plan with a 401(k)
salary deferral feature that covers substantially all of its employees who meet
certain requirements. Under the terms of the plan, employees may contribute up
to 14% of gross earnings and the Company will provide a matching contribution of
50% of the first 5% of gross earnings contributed by the participants. The
Company may, at its option, make additional contributions. The terms of the plan
provide for vesting in the Company's matching contributions to the plan over a
five-year service period with 50% vesting after year three, an additional 25%
vesting after year four, and participants will be fully vested after year five.
The Company expensed contributions for the retirement plan of $0.1 million for
the thirteen weeks ended May 1, 2004 and $0.1 million for the thirteen weeks
ended May 3, 2003.

     The Company maintains a supplemental executive retirement plan ("SERP")
which is a nonqualified defined benefit plan for certain officers. The plan is
noncontributory and provides benefits based on years of service and compensation
during employment. Pension expense is determined using various actuarial cost
methods to estimate the total benefits ultimately payable to officers and
allocates this cost to service periods. The pension plan is unfunded. The
actuarial assumptions used to calculate pension costs are reviewed annually.

     The components of net periodic pension benefit cost are as follows:

     The Company expects to make a contribution to the pension plan of
approximately $2.4 million in Fiscal 2004. This contribution will be made in
connection with the retirement of John S. Mills, our President and Chief
Operating Officer. No contributions have been made during the thirteen weeks
ended May 1, 2004.

     During the thirteen weeks ended May 1, 2004, the Company adopted the
"Aeropostale, Inc. Long-Term Incentive Deferred Compensation Plan". The plan is
a non-qualified, defined contribution plan established for the purpose of
providing long-term incentive to a select group of management. Participants in
this plan include all employees designated by the Company as Vice President or
other higher-ranking position who are not participants of the "Aeropostale, Inc.
Supplemental Executive Retirement Plan". This plan is unfunded.

     The Company will record annual unfunded monetary credits to each
participant's account based on compensation levels and years as a participant in
the plan. Annual interest credits will be applied to the balance of each
participant's account based upon established benchmarks. Each annual credit is
subject to a three year cliff vesting schedule. The participant's account will
be 100% vested upon retirement after completing five years of service and
attaining age 55.

     During the thirteen weeks ended May 1, 2004, the Company recorded an
expense of $0.2 million related to this plan.

8. GUARANTEES

     The Company has not provided any financial guarantees as of May 1, 2004.

9. STOCK REPURCHASE PROGRAM AND RESTRICTED STOCK AWARDS

     On November 20, 2003, the Company announced that its Board of Directors had
approved a stock repurchase program to acquire up to $35.0 million of
outstanding Common Stock. The stock repurchase program has been extended from
time to time and, on April 12, 2004, the Company's Board of Directors approved
the repurchase of an additional $35.0 million of outstanding Common Stock. This
additional authorization increased the total share repurchase program to $70.0
million. There is no expiration date for the program. The extent and timing of
repurchases will depend upon general business and market conditions, stock
prices, and requirements going forward. The repurchase program may be modified
or terminated by the Board of Directors at any time. During the thirteen weeks
ended May 1, 2004, the Company repurchased 828 thousand shares for $18.6
million. As of May 1, 2004, the Company purchased a total of 1.8 million shares
for $36.3 million, since the inception of the repurchase program.

     On March 12, 2004, certain executives and directors of the Company were
awarded a total of 79 thousand shares of Restricted Stock, pursuant to
restricted stock agreements. The restricted stock awarded to employees vest at
the end of three years of continuous service with the Company. The restricted
stock awarded to directors vest pro-rata over a three year period, based upon
continuous service to the Company. The restricted stock awards are accounted for
as a component of stockholders' equity with respect to unamortized stock based
compensation. However, such shares are not considered outstanding. Total
compensation expense of $1.8 million is being amortized over the vesting period.
Amortization expense for the thirteen weeks ended May 1, 2004 totaled $0.1
million.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
                                 OF OPERATIONS
             (AMOUNT IN THOUSANDS, EXCEPT PER SHARE AND STORE DATA)

INTRODUCTION

     Aeropostale, Inc. is a mall-based specialty retailer of casual apparel and
accessories that targets both young women and young men aged 11 to 20. We
provide customers with a selection of high-quality, active-oriented, fashion
basic merchandise at compelling values in a high-energy store environment. We
maintain complete control over our proprietary brand by designing and sourcing
all of our own merchandise. Our products can be purchased only in our stores,
which sell Aeropostale merchandise exclusively, or organized sales events at
college campuses. As of May 1, 2004, we operated 489 stores in 42 states.

OVERVIEW

     We achieved total net sales of $167.7 million for the first quarter of
Fiscal 2004, an increase of $55.5 million or 49.5% from the prior year. This was
attributable to an increase of 25.8% in square footage growth of our store base,
coupled with an 18.9% comparable store sales gain. Our sales results reflect
growth in each of our three categories: women's, men's and accessories, which we
believe is attributable to our trend right merchandise assortment, increased
inventory levels to capitalize on sales opportunities and a general increase in
overall mall traffic levels.

     Our gross profit as a percentage of net sales improved from 27.0% last year
to 29.3% primarily as a result of leverage of occupancy costs and efficiencies
realized in our warehouse. The increase in gross profit as a percentage of net
sales was partially offset by a decrease in merchandise margin primarily as a
result of the discontinuation of one of the styles in our womens graphic tee
classification. Our selling, general and administrative expenses declined as a
percentage of sales from 24.0% to 23.3%. The improvement was primarily driven by
leverage of storeline and operational costs, partially offset by increased
marketing expenses and a one time executive retirement charge. As a result, our
operating profit as a percentage of net sales improved from 2.9% to 6.0%. Our
net income for the quarter increased 196.4% to $6.3 million, compared to $2.1
million for the same period last year, and our earnings per diluted share
increased 175.0% to $0.11.

     Cash balances at the end of the quarter were $104.1 million and we were
able to fund all of our growth and cash requirements from our cash on hand.
During the quarter, we purchased 828 thousand shares of our common stock at a
cost of $18.6 million.

  Thirteen weeks ended May 1, 2004 compared to thirteen weeks ended May 3, 2003.

     Net sales.  Our net sales were $167.7 million for the thirteen weeks ended
May 1, 2004, compared to $112.2 million for the thirteen weeks ended May 3,
2003, an increase of $55.5 million. Of this increase, comparable store sales
contributed $20.0 million and non-comparable store sales contributed $35.5
million. Comparable store sales increased by 18.9% for the thirteen weeks ended
May 1, 2004, compared to an increase of 1.8% for the thirteen weeks ended May 3,
2003. The comparable stores sales increase was driven by an increase in units
per transaction of 6.6% and an increase in the number of sales transactions of
15.9%. The average dollar unit decreased 3.7% primarily as a result of higher
comparable store sales in the accessories category, which carry lower price
points, as compared to apparel merchandise. Comparable sales increased in all
three categories -- young women's, young men's and accessories. The increase in
non-comparable store sales was primarily due to 102 more stores open at the end
of the thirteen weeks ended May 1, 2004, as compared to the comparable period
last year.

     Gross profit.  Our gross profit was $49.1 million for the thirteen weeks
ended May 1, 2004, compared to $30.3 million in the thirteen weeks ended May 3,
2003, an increase of $18.8 million. As a percentage of net sales, gross profit
increased to 29.3% from 27.0% in the comparable period last year. The increase
of 2.3% is attributable to 2.2% leverage of occupancy costs, 0.6% improvement in
distribution costs and 0.2% leverage of depreciation. This increase was
partially offset by 0.7% decrease in our merchandise margin primarily associated
with the discontinuation of one of the styles in our womens graphic tee
classification.

     Selling, general and administrative expenses.  Our selling, general and
administrative expenses were $39.1 million for the thirteen weeks ended May 1,
2004, compared to $27.0 million in the thirteen weeks ended May 3, 2003, an
increase of $12.1 million. This $12.1 million increase is primarily attributable
to a $7.3 million increase in payroll and benefit costs, $2.3 million increase
in operational costs, $1.4 million one time retirement charge and $1.1 million
increase in marketing expenses. As a percentage of sales, selling, general and
administrative expenses decreased to 23.3% from 24.0% during these periods. The
0.7% decrease was primarily attributable to 2.0% decrease in store line and
operational costs, offset by 0.8% one time retirement plan charge and 0.5%
increase in marketing expenses.

     Interest income, net.  Our net interest income was $0.3 million for the
thirteen weeks ended May 1, 2004, compared to net interest income of $0.2
million for the thirteen weeks ended May 3, 2003, primarily due to higher cash
balances.

     Income taxes.  Our effective tax rate was 39.0% for both the thirteen weeks
ended May 1, 2004 and May 3, 2003.

     Net income.  Our net income was $6.3 million for the thirteen weeks ended
May 1, 2004 compared to $2.1 million for the thirteen weeks ended May 3, 2003.
Diluted earnings per share increased 175.0% to $0.11 in the thirteen weeks ended
May 1, 2004 from $0.04 per diluted share in the thirteen weeks ended May 3,
2003.

    Liquidity and Capital Resources

     Our cash requirements are primarily for working capital, the construction
of new stores, the remodeling of existing stores, and the investment in our
information systems. Historically, these cash requirements have been met through
cash flow from operations and borrowings under our credit facility with Fleet
Retail Finance, Inc. At May 1, 2004, we had working capital of $128.5 million.

     The following table sets forth our cash flows for the period indicated:

</Table>

     Operating activities -- For the thirteen weeks ended May 1, 2004, we had a
net decrease in cash and cash equivalents of $34.3 million. Our cash used in
operations for the thirteen weeks ended May 1, 2004 was $3.7 million. The cash
used in operations was primarily for the purchase of inventory, the increase in
other current assets and the decrease in accrued and other liabilities.

     Investing activities -- Our cash used in investing activities for the
thirteen weeks ended May 1, 2004 was entirely used for capital expenditures.
These expenditures, consisting primarily of the construction of new stores,
remodeling of existing stores and investments in technology, were $12.2 million
for the thirteen weeks ended May 1, 2004. Our future capital requirements will
depend primarily on the number of new stores we open, the number of existing
stores we remodel and the timing of these expenditures. Projected

                                        12
<PAGE>

capital expenditures for Fiscal 2004 are approximately $45.5 million, to be used
primarily to fund new store openings, the remodeling of existing stores and
technology investments. Historically, we have financed such capital expenditures
with cash from operations and borrowings under our credit facility. We opened 30
new stores during the thirteen weeks ended May 1, 2004 and expect to open
approximately 65 additional stores in the remainder of Fiscal 2004.

     Financing activities -- Our cash used in financing activities for the
thirteen weeks ended May 1, 2004 was $18.4 million primarily used to finance our
share repurchase program. We also received proceeds of $0.2 million from the
exercise of stock options during this period. On March 9, 2004, our Board of
Directors authorized an additional $35.0 million in our share repurchase
program. This additional authorization brought the total share repurchase
program to $70.0 million. During the thirteen weeks ended May 1, 2004, we
repurchased 828 thousand shares for $18.6 million.

     As of May 1, 2004, we had $104.1 million in cash available to fund
operations and future store growth. In addition, we had $25.0 million available
for borrowings under our credit facility. We believe that cash flows from
operations, our current cash balance and funds available under our revolving
credit facility will be sufficient to meet our working capital needs, planned
capital expenditures, and share repurchases for Fiscal 2004.

     Our secured revolving credit facility with Fleet provides us with up to $25
million (the "Credit Facility"). Borrowings bear interest at our option at
either (i) the rate per annum at which deposits on U.S. dollars are offered to
Fleet in the Eurodollar market, referred to as the Eurodollar Rate, plus 1.25%
to 1.75% or (ii) the base rate announced from time to time by Fleet. As of May
1, 2004, there were no amounts outstanding under the Credit Facility. The Credit
Facility contains certain negative covenants, including but not limited to,
limitations on the Company's ability to incur other indebtedness, encumber its
assets or undergo a change of control. Additionally, the Company is required to
keep a ratio of 2:1 of the value of the Company's inventory to the amounts
outstanding at any time under the Credit Facility. The Credit Facility has a
termination date of September 2005. There are fees for early termination.

     Events of default under the credit facility include, subject to grace
periods and notice provisions in certain circumstances, failure to pay principal
amounts when due, breaches of covenants, misrepresentation, default of leases or
other indebtedness, excess uninsured casualty loss, excess uninsured judgment or
restraint of business, business failure or application for bankruptcy,
indictment of or institution of any legal process or proceeding under federal,
state, municipal or civil statutes, legal challenges to loan documents, and a
change in control. If an event of default occurs, the lenders under the Credit
Facility will be entitled to take various actions, including the acceleration of
amounts due thereunder and requiring that all such amounts be immediately paid
in full as well as possession and sale of all assets that have been used as
collateral.

     We have not issued any letters of credit for the purchase of merchandise
inventory or any capital expenditures.

     There were no commercial commitments outstanding as of May 1, 2004.

     Off-Balance Sheet Arrangements

     The Company has not created, and is not party to, any special-purpose or
off-balance sheet entities for the purpose of raising capital, incurring debt or
operating the Company's business. The Company does not have any arrangements or
relationships with entities that are not consolidated into the financial
statements that are reasonably likely to materially affect the Company's
liquidity or the availability of capital resources.

     Critical Accounting Policies and Management Estimates

     Net sales.  Net sales consist of sales from comparable stores and
non-comparable stores. A store is not included in comparable store sales until
the first day of the fiscal month following the fourteenth full fiscal month of
sales. Non-comparable store sales include sales in the current fiscal year from
our stores opened during the previous fiscal year before they are considered
comparable stores and new stores opened during the current fiscal year. In
addition, all sales generated from stores that we have closed and through our
arrangements with colleges and universities for organized sales events are
included in non-comparable store sales.

     Cost of sales.  Cost of sales includes the cost of merchandise,
distribution and warehousing, freight from the distribution center and warehouse
to the stores, payroll for our design, buying and merchandising personnel and
store occupancy costs. Store occupancy costs include rent, contingent rents,
common area maintenance, real estate taxes, utilities, repairs, maintenance and
depreciation.

     Selling, general and administrative expenses.  Selling, general and
administrative expenses include selling, store management and corporate
expenses, including payroll and employee benefits, other than for our design,
buying and merchandising personnel, employment taxes, management information
systems, marketing, insurance, legal, store pre-opening and other corporate
level expenses. Store pre-opening expenses include store level payroll, grand
opening event marketing, travel, supplies and other store opening expenses.
Corporate level expenses are primarily attributable to our corporate offices in
New York, New York, and Wayne, New Jersey.

     Interest income, net.  Interest income, net of interest expense, includes
interest relating to our cash balances.

CRITICAL ACCOUNTING POLICIES

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires the
appropriate application of certain accounting policies, many of which require us
to make estimates and assumptions about future events and their impact on
amounts

                                        14
<PAGE>

reported in our financial statements and related notes. Since future events and
their impact cannot be determined with certainty, the actual results will
inevitably differ from our estimates. Such differences could be material to the
consolidated financial statements.

     We believe application of accounting policies, and the estimates inherently
required therein, are reasonable. These accounting policies and estimates are
constantly reevaluated, and adjustments are made when facts and circumstances
dictate a change. Historically, we have found our application of accounting
policies to be appropriate, and actual results have not differed materially from
those determined using necessary estimates.

     Our accounting policies are more fully described in Note 2 to the
consolidated financial statements in the Company's Annual Report on Form 10-K
for the fiscal year ended January 31, 2004. We have identified certain critical
accounting policies which require significant management estimates and are
described below.

     Merchandise inventory.  Inventory consists of finished goods and is valued
utilizing the cost method at lower of cost or market on a first-in, first-out
basis. In order to assess that our inventory is recorded properly at the lower
of cost or market, we make certain assumptions regarding future demand and net
realizable selling price. These assumptions are based on historical experience
and current information and can have a significant impact on current and future
operating results and financial position.

     Finite-lived assets.  In evaluating the fair value and future benefits of
finite-lived assets, we perform an analysis of the anticipated undiscounted
future net cash flows of the related finite-lived assets and reduce their
carrying value by the excess, if any, of the result of such calculation. This
analysis includes factors such as future sales and projected profit margins. We
believe at this time that the finite-lived assets' carrying values and useful
lives continues to be appropriate.

NEW ACCOUNTING STANDARDS

     In December 2003, the FASB issued FAS No. 132 (Revised) ("FAS 132-R"),
Employer's Disclosure about Pensions and Other Postretirement Benefits. FAS
132-R retains disclosure requirements of the original FAS 132 and requires
additional disclosures relating to assets, obligations, cash flows, and net
periodic benefit cost. FAS 132-R is effective for fiscal years ending after
December 15, 2003, except that certain disclosures are effective for fiscal
years ending after June 15, 2004. Interim period disclosures are effective for
interim periods beginning after December 15, 2003. The adoption of the
disclosure provisions of FAS 132-R did not have a material effect on the
Company's condensed consolidated financial statements.

     In March 2004, the FASB published an Exposure Draft, Shares-Based Payment,
an amendment of FASB Statements No. 123 and 95. Under this FASB proposal, all
forms of share-based payment to employees, including employee stock options,
would be treated as compensation and recognized in the income statement. This
proposed statement would be effective for fiscal years beginning after December
15, 2004. The Company currently accounts for stock options under APB No. 25. The
pro-forma impact of expensing options is disclosed in Note 2 of Notes to
Unaudited Condensed Consolidated Financial Statements.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS AND RISK FACTORS

     This report on Form 10-Q contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Such forward-looking statements involve certain
risks and uncertainties, including statements regarding the company's strategic
direction, prospects and future results. Certain factors, including factors
outside of our control, may cause actual results to differ materially from those
contained in the forward-looking statements. All forward looking statements
included in this report are based on information available to us as of the date
hereof, and we assume no obligation to update or revise such forward-looking
statements to reflect events or circumstances that occur after such statements
are made. Such uncertainties and other risks are discussed

<PAGE>

in the Company's Form 10-K for the year ended January 31, 2004, filed with the
Securities and Exchange Commission on April 14, 2004.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company, in the normal course of doing business, is theoretically
exposed to interest rate change market risk. As borrowing patterns are seasonal,
the Company is not dependent on borrowing for the entire year. Therefore, a
sudden increase in interest rates (which under the Loan Agreement is dependent
on the prime rate) may, during peak borrowing, have a negative impact on
short-term results.

ITEM 4.  CONTROLS AND PROCEDURES

     (a) Explanation of disclosure controls and procedures:  The Company,
including its Chief Executive Officer and Chief Financial Officer, carried out
an evaluation, of the effectiveness of the design and operation of the Company's
disclosure controls and procedures pursuant to Exchange Act Rule 13a-14(c) and
15d-14(c) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). Based upon that evaluation, the Company's Chief Executive Officer along
with the Company's Chief Financial Officer concluded that as of the end of the
period covered by this report, the Company's disclosure controls and procedures
were effective to ensure that information it is required to disclose in its
filings with the SEC under the Exchange Act is recorded, processed, summarized
and reported, within the time periods specified in the SEC's rules and forms,
and to ensure that information that it is required to disclose in the reports
that it files under the Exchange Act is accumulated and communicated to its
management, including its principal executive officer and principal financial
officer, as appropriate to allow timely decisions regarding disclosure. It
should be noted, however, that the design of any system of controls is limited
in its ability to detect errors and there can, therefore, be no assurance that
any design will succeed in achieving its stated goals under all potential future
conditions, regardless of how remote.

     (b) Changes in internal controls:  During the period covered by this
quarterly report, there have been no changes to the Company's internal control
over financial reporting that have materially affected, or are reasonably likely
to materially affect the Company's internal control over financial reporting.

     Not applicable.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

     On November 20, 2003, the Company's Board of Directors authorized a share
repurchase program of its outstanding common stock in the amount of $35.0
million. On March 9, 2004, the Company announced that its Board of Directors had
approved an increase in its share repurchase program to acquire an additional
$35.0 million of its common stock. The additional authorization increased the
total share repurchase program to $70.0 million. The Company's purchases of
treasury stock for the thirteen weeks ended May 1, 2004 pursuant to the share
repurchase program are as follows (amounts in thousands, except for share price
data):
