                         Report of Independent Auditors

Plan Administrator
LESCO, Inc. Stock Investment and
   Salary Savings Plan and Trust

We have audited the accompanying statements of net assets available for benefits
of LESCO, Inc. Stock Investment and Salary Savings Plan and Trust as of December
31, 2001 and 2000, and the related statement of changes in net assets available
for benefits for the year ended December 31, 2001. These financial statements
are the responsibility of the Plan's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2001 and 2000, and the changes in its net assets available for
benefits for the year ended December 31, 2001 in conformity with accounting
principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2001 is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. This supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                                                           /s/ Ernst & Young LLP

         LESCO, Inc. Stock Investment and Salary Savings Plan and Trust

                          Notes to Financial Statements

                         December 31, 2001 and 2000 and
                          Year ended December 31, 2001

1. DESCRIPTION OF THE PLAN

The LESCO, Inc. Stock Investment and Salary Savings Plan and Trust (the Plan) is
a defined contribution plan covering substantially all employees of LESCO, Inc.
(the Company). The Plan is subject to the provisions of the Employee Retirement
Income Security Act of 1974 (ERISA).

The following description of the Plan provides only general information.
Participants should refer to the plan document for a more complete description
of the Plan's provisions.

CONTRIBUTIONS

An employee electing to become a participant in the Plan authorizes a payroll
deduction from eligible earnings for contributions to the Plan in accordance
with the Plan document and the Internal Revenue Code (the Code). A participant
may direct contributions to be invested in any or all of the investment options
offered by the Plan.

The Plan provides that the Company shall contribute to the Plan an amount equal
to 25% of the first 10% of eligible earnings that a participant contributes to
the Plan. The Company may contribute an additional amount to the Plan at its
discretion either in the form of cash or employer stock which would be allocated
to each active participant's account based on the participant's annual
compensation. There were no discretionary contributions during 2001. Employer
contributions are allocated among the investment options offered by the Plan
according to the participant's election.

The Plan provides for the acceptance of rollover contributions from other plans
qualified under the Code.

VESTING

Participant and Company matching contributions are fully vested immediately.
Company discretionary contributions vest at the rate of 10% per year for the
first four years following contribution and 20% per year thereafter, until fully
vested. All contributions are fully vested when the participant reaches age 65.
Upon termination of employment with the Company, the nonvested portion of the
participant's account is forfeited. Forfeited account balances are allocated
amongst active participants.

                    Notes to Financial Statements (continued)


1. DESCRIPTION OF PLAN (CONTINUED)

PARTICIPANT ACCOUNTS

Individual accounts are maintained for participants which are adjusted for
contributions and allocation of Plan earnings. Plan earnings are allocated to
participant accounts in proportion to the value of account balances.

LOANS

Participants may borrow from their fund accounts up to an amount equal to the
lesser of $50,000 or 50% of the value of their vested account balance at the
date the loan is made. Loans are secured by the balance in the participant's
account and bear interest at the prime rate in effect at the date of the loan,
plus one percent. Loan terms range from one to five years, or up to 30 years if
used for the purchase of a primary residence. Repayment of loan principal and
interest is made through payroll deductions over the term of the loan.

PAYMENT OF BENEFITS

A participant is entitled to receive the vested full value of his or her account
at age 65, upon death or disability prior to retirement, or upon termination of
employment. Upon retirement or termination, the participant may elect to receive
the distribution in a lump sum or a series of installments.

PLAN TERMINATION

Although it has not expressed an intent to do so, the Company has the right to
discontinue its contributions to the Plan at any time and to terminate the Plan
subject to the provisions of ERISA. In the event of termination of the Plan, all
participants' accounts become fully vested, and will be distributed to the
participants according to the directions of the Plan Advisory Committee
administering the Plan.

ADMINISTRATIVE EXPENSES

All significant accounting and administrative fees are paid by the Company at
the Company's discretion. Expenses not paid by the Company are paid out of Plan
assets.

                    Notes to Financial Statements (continued)

2. SIGNIFICANT ACCOUNTING POLICIES

The Plan's financial statements are reported on the accrual basis of accounting.

Investments are stated at fair value. The investment in LESCO, Inc. Common
Stock, which is traded on a national securities exchange, is valued at the last
reported sales price on the last business day of the year. The shares of
registered investment companies are valued at quoted market prices which
represent the net asset values of shares held by the Plan at year-end. The
investment in the common trust fund is valued based on the redemption price of
units in the fund, which is based on the market values of the underlying assets
of the fund. Participant loans are valued at their outstanding balances, which
approximate fair value.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
that affect the amounts reported in the financial statements and accompanying
notes. Actual results may differ from these estimates.

3. INVESTMENTS

The Plan's investments are held by a bank-administered trust fund. Net realized
and unrealized (depreciation) appreciation in the fair value of investments for
the year ended December 31, 2001 is as follows:

Common stock                                       $    (2,374,186)
Shares of registered investment companies               (2,884,042)
Common trust fund                                          320,736

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated January 16, 1996, stating that the Plan is qualified under Section 401(a)
of the Code and, therefore, the related trust is exempt from taxation. Once
qualified, the Plan is required to operate in conformity with the Code to
maintain its qualification. The Plan administrator believes the Plan is being
operated in compliance with the applicable requirements of the Code and
therefore, believes that the Plan is qualified and the related trust is tax
exempt.
