issued, by it at such times, for such considerations and upon such terms and

     EIGHTH: The Corporation reserves the right at any time and from time to
time substantially to change, alter, add to or diminish its purposes as
specified in these Amended Articles of Incorporation in any manner new or
hereafter permitted by law. Any such change in the purposes of the Corporation
if accomplished in a manner now or hereafter permitted by law shall be binding
and conclusive upon every shareholder of the Corporation as fully as if such

cash value of his shares or of any other rights of a dissenting shareholder.

     NINTH: No officer, director or shareholder of the Corporation shall be
disqualified by his office, membership on the Board of Directors or share

contracting with the Corporation as a vendor, purchaser, employee, agent or in
any other similar or dissimilar capacity nor shall any transaction, contract or
act of the Corporation be void or voidable or in any way affected or invalidated

Corporation, any firm of which he may be a member or any other corporation of
which he may be an officer, director or shareholder, is in any way interested in
such transaction, contract or act, provided the interest of such officer,
director or shareholder is disclosed to or known by the Board of Directors of
this Corporation or such members thereof as shall be present at any meeting at

such officer, director or shareholder be accountable or otherwise responsible to

for any gains or profits realized by him by reason of the fact that he, any firm
of which he is a member, or any other corporation of which he is an officer,
director or shareholder, is interested in any such transaction, contract or act.
Any such officer, director or shareholder, if he is a director, may be counted
in determining the existence of quorum at any meeting of the Board of Directors
of the Corporation which shall authorize or take action upon any such
transaction, contract or act and he may vote at any such meeting to authorize,
ratify or approve any such, transaction, contract or act to the same extent as
if he, any firm of which he is a member or any other Corporation of which he is
a officer, director or shareholder were not interested in such transaction,
contract or act.

     TENTH: These Amended Articles of Incorporation supersede the existing
Articles of Incorporation of the Corporation and all amendments thereto and may
be amended, altered or repealed, in whole or in part, at any time and from time
to time in the manner provided in these Amended Articles of Incorporation and by
law, and all rights conferred upon shareholders herein are granted subject to
this reservation.

     William A. Foley, President and Chief Executive Officer, and Daniel G.
Dunstan, Secretary, of LESCO, INC., an Ohio corporation (the "Corporation").
with its principal office located at 20005 Lake Road, Rocky River, Ohio 44116,
do hereby certify that the following resolution amending the Articles of
Incorporation was adopted by the Board of Directors of the Corporation at a
meeting of such Directors on May 18, 1994 and that pursuant to Article FOURTH of
the Corporation's Articles of Incorporation and Section 1701.06(12) of the Ohio

     RESOLVED: That Article "FOURTH" of the Corporation's Articles of

               C. Dividends and Distributions.

                    (1) Subject to any prior and superior rights of the holders
               of any series of Preferred Shares ranking prior and superior to
               the Series A Preferred Shares with respect to dividends, holders
               of Series A Preferred Shares shall be entitled, prior to the
               payment of any dividends on shares ranking junior to the Series A
               Preferred Shares, to receive, when, as, and if declared by the
               Board of Directors out of funds legally available for the
               purpose, quarterly dividends payable in cash on the last day of
               March, June, September, and December in each year (each such date
               being referred to herein as a "Quarterly Dividend Payment Date"),
               commencing on the first Quarterly Dividend Payment Date after the
               first issuance of Series A Preferred Shares, in an amount per
               share (rounded to the nearest cent) equal to the greater of (a)
               $1.00 and (b) subject to the provisions for adjustment
               hereinafter set forth, 100 times the aggregate per share amount
               of all cash dividends, and 100 times the aggregate per share
               amount (payable in kind) of all non-cash dividends or other
               distributions (other than a dividend payable in Common Shares or
               a subdivision of the outstanding Common Shares, by
               reclassification or otherwise), declared on the Common Shares
               since the immediately preceding Quarterly Dividend Payment Date
               or, with respect to the first Quarterly Dividend Payment Date,
               since the first issuance of any Series A Preferred Share or
               fraction thereof. In the event the Company at any time after May
               18, 1994 (the "Rights Declaration Date") (i) declares any
               dividend on Common Shares payable in Common Shares, (ii)
               subdivides the outstanding Common Shares, or (iii) combines the
               outstanding Common Shares into a smaller number of shares, the
               amount to which holders of Series A Preferred Shares entitled
               under clause (b) of the preceding sentence shall in each such
               case be adjusted by multiplying the amount to which they were
               entitled immediately prior to such event by a fraction the
               numerator of which is the number of Common Shares outstanding
               immediately after such event and the denominator of which is the
               number of Common Shares outstanding immediately prior to such
               event.

                    (2) The Company shall declare a dividend or distribution on
               the Series A Preferred Shares as provided in paragraph (1) of
               this section C immediately after it declares a dividend or
               distribution on the Common Shares (other than a dividend payable
               in Common Shares), except that, in the event no dividend or
               distribution has been declared on the Common Shares during the
               period between any Quarterly Dividend Payment Date and the next
               subsequent Quarterly Dividend Payment Date, subject to paragraph
               3 of this Section C, a dividend of $1.00 per share on the Series
               A Preferred Shares shall nevertheless be fully accrued as of such
               subsequent Quarterly Dividend Payment Date.

                    (3) Dividends shall, begin to accrue and be cumulative on
               outstanding Series A Preferred Shares from the Quarterly Dividend
               Payment Date next preceding the date of issue of the Series A
               Preferred Shares, unless the date of issue of the Series A
               Preferred Shares is prior to the record date for the First
               Quarterly Dividend Payment Date, in which case dividends on the
               Series A Preferred Shares shall begin to accrue from the date of
               issue of the Series A


                                       2
<PAGE>

          Preferred Shares, or unless the date of issue is a Quarterly Dividend
          Payment Date or is a date after the record date for the determination
          of holders of Series A Preferred Shares entitled to receive a
          Quarterly Dividend and before such Quarterly Dividend Payment Date, in
          either of which events such dividends shall begin to accrue and be
          cumulative from such Quarterly Dividend Payment Date.

               (4) Accrued but unpaid dividends shall not bear interest.
          Dividends paid on the Series A Preferred Shares in an amount less than
          the total amount of such dividends at the time accrued and payable on
          the Series A Preferred Share shall be allocated pro rata on a
          share-by-share basis among all the Series A Preferred Shares at the
          time outstanding. The Board of Directors may fix a record date for the
          determination of holders of Series A Preferred Shares entitled to
          receive payment of a dividend or distribution declared thereon, which
          record date shall be no more than 60 days prior to the date fixed for
          the payment thereof.

               D. Liquidation. Dissolution, or Winding Up.

               (1) Upon any liquidation, dissolution, or winding up of the
          Company, no distribution shall be made to the holders of shares
          ranking junior (either as to dividends or upon liquidation,
          dissolution, or winding up) to the Series A Preferred Shares unless,
          prior thereto, the holders of Series A Preferred Shares have received
          $10.00 per share, plus an amount equal to accrued and unpaid dividends
          and distributions on the Series A Preferred Shares, whether or not
          declared, to the date of such payment (the "Series A Liquidation
          Preference"). Following the payment of the full amount of the Series A
          Liquidation Preference, no additional distributions shall be made to
          the holders of Series A Preferred Shares unless, prior, thereto, the
          holders of Common Shares have received an amount per share (the
          "Common Adjustment") equal to the quotient obtained by dividing (i)
          the Series A Liquidation Preference by (ii) 100 (as appropriately
          adjusted in accordance with paragraph (3) of this section D to reflect
          events such as stock splits, stock dividends and recapitalizations
          with respect to the Common Shares), such number, as adjusted, being
          hereinafter referred to as the "Adjustment Number". Following the
          payment of the full amount of the Series A Liquidation Preference and
          the Common Adjustment in respect of all outstanding Series A Preferred
          Shares and Common Shares, respectively, holders of Series A Preferred
          Shares and holders of Common Shares shall receive their ratable and
          proportionate share, on a per share basis, of the remaining assets to
          be distributed in the ratio that the Adjustment Number bears to 1.0
          with respect to such Series A Preferred Shares and Common Shares,
          respectively.

               (2) In the event, however, that there are not sufficient assets
          available to permit the payment in full of the Series A Liquidation
          Preference and the liquidation preference of all other series of
          Preferred Shares, if any, that rank on a parity with the Series A
          Preferred Shares, such remaining assets shall be distributed ratably
          to the holders of such parity shares in proportion to their respective
          liquidation preferences. Similarly, in the event there are not
          sufficient


                                        3

<PAGE>

          assets available to permit payment in full of the Common Adjustment,
          such remaining assets shall be distributed ratably to the holders of
          Common Shares.

               (3) In the event the Company at any time after the Rights
          Declaration Date (i) declares any dividend on Common Shares payable in
          Common Shares, (ii) subdivides the outstanding Common Shares, or (iii)
          combines the outstanding Common Shares into a smaller number of
          shares, then the Adjustment Number in effect immediately prior to such
          event shall in each such case be adjusted by multiplying such
          Adjustment Number by a fraction the numerator of which is the number
          of Common Shares outstanding immediately after such event and the
          denominator of which is the number of Common Shares outstanding
          immediately prior to such event.

               E. Conversion on Merger, Consolidation, etc. In case the Company
          enters into any merger, consolidation, combination, or other
          transaction in which Common Shares are exchanged or changed into other
          shares or securities, cash, or other property, each Series A Preferred
          Share shall in any such case at the same time be similarly exchanged
          or changed in an amount per share (subject to the provision for
          adjustment hereinafter set forth) equal to 100 times the aggregate
          amount of shares, securities, cash or other property (payable in
          kind), as the case may be, into which or For which each Common Share
          is changed or exchanged. In the event the Company at any time after
          the Rights Declaration Date (i) declares any dividend on Common Shares
          payable in Common Shares, (ii) subdivides the outstanding Common
          Shares, or (iii) combines the outstanding Common Shares into a smaller
          number of shares, the amount set forth in the preceding sentence With
          respect to the-exchange or change of Series A Preferred Shares shall
          in each such case be adjusted by multiplying such amount by a
          fraction, the numerator of which is the number of Common Shares
          outstanding immediately after such event and the denominator of which
          is the number of Common Shares, outstanding immediately prior to such
          event.

               F. Redemption. The outstanding Series A Preferred Shares shall
          not be redeemable.

               G. Condition to Issuance of Any Other Series. The Amended
          Articles of Incorporation of the Company shall not be further amended
          to provide for the issuance of any other series of Preferred Shares
          without the affirmative vote of the


                                        4

          holders of at least two-thirds of the outstanding Series A Preferred
          shares; voting separately as a class.
