RESPONSIBLE OFFICER:      President and Chief Executive Officer

PROCEDURE:

     I.   CONFLICT OF INTEREST

          Associates shall ethically handle all actual or apparent conflicts of
          interest between personal and professional relationships. To the
          extent reasonable, possible conflicts of interest and apparent
          conflicts of interest should be avoided. When an Associate, or members
          of their immediate family, interferes or appears to interfere in any
          way with the interest of the Company, a conflict of interest can
          arise. These conflicts may materialize under several circumstances,

               or competitor;

          B.   Owning a financial interest in, or serving in a business capacity
               with, an outside enterprise that does or wishes to do business
               with, or is a competitor of the Company;

          C.   Serving as an intermediary for the benefit of a third party in
               transactions involving the Company;

          D.   Using confidential Company information or other Company assets
               for personal profit, conducting business for another enterprise
               during Company working hours or using Company property to conduct
               business for another enterprise; or

          E.   Employment in addition to employment with the Company (Refer to
               #C-49 Employment in Addition to LESCO).

          from the Company's suppliers, potential suppliers, customers or
          potential customers. It is the Company's policy to discourage the
          receipt of gifts either directly or indirectly by Associates as any
          gift may be misconstrued as an attempt to influence business
          decisions.

     V.   DISCRIMINATION AND HARASSMENT

          harassment, intimidation and coercion on any basis prohibited by law

           posting in the Company's website.

     X.   VIOLATIONS OF THE CODE

          A.   Reporting Violations of the Code

               1.   Each Associate shall comply with the letter and the spirit
                    of the Code of Business Conduct and with the policies and
                    procedures of the Company, and shall report any suspected
                    violations promptly to: the Company's Chief Financial
                    Officer or the persons or confidential integrity hotline
                    identified in the Company's Corporate Policy #C-069, Policy
                    for Reporting Integrity Issues.

               2.   The Company shall not take adverse employment action against
                    an Associate in retaliation for any reports of suspected
                    violations made in good faith or for participating in an
                    investigation, hearing, court proceeding or another
                    administrative inquiry in connection with or as a result of
                    a report of a suspected violation. This Code of Business
                    Conduct is intended to encourage reporting of suspected
                    violations by Associates and presumes that Associates will
                    act in good faith and will not make false accusations. An
                    Associate who knowingly or recklessly makes statements or
                    disclosures that are not in good faith may be subject to
                    discipline, which may include termination. Associates who
                    report suspected violations of this Code pursuant to this
                    Code can and will continue to be held to the Company's
                    general job performance standards. Therefore, an Associate
                    against whom legitimate adverse employment actions have been
                    taken or are proposed to be taken for reasons other than
                    prohibited retaliatory actions, such as poor job performance
                    or misconduct by the Associate, is prohibited from using
                    this Code as a defense against the Company's lawful actions.

                    For purposes of this policy:


                    (1)  Good Faith - Good faith is evident when the report is
                         made without malice or consideration of personal
                         benefit and the Associate has a


                                       3

Exhibit 14                                              Corporate Policy #C-039
                                                 Issue Date:  December 15, 2003


                         reasonable basis to believe the report is true;
                         provided, however, a report does not have to be proven
                         to be true to be made in good faith. Good faith is
                         lacking when the disclosure is known to be malicious,
                         false or frivolous.

                    (2)  Adverse Employment Action - Examples of adverse
                         employment action include, but are not limited to,
                         demotion, suspension, termination, transfer to a lesser
                         position, denial of promotions, denial of benefits,
                         threats, harassment, denial of compensation and
                         privileges as a result of the employee's report of
                         wrongdoing, or any manner of discrimination against an
                         Associate in the terms and conditions of employment
                         because of any other lawful act done by the employee
                         pursuant to this policy or Section 806 of the
                         Sarbanes-Oxley Act of 2002.

               3.   In order to facilitate implementation of this Code of
                    Business Conduct and Ethics, Associates have a duty to
                    cooperate fully with the investigation process and to
                    maintain the confidentiality of investigative information
                    unless specifically authorized to disclose such information.

          B.   Discipline for Violation of the Code

               1.   After a full and impartial investigation concerning
                    violations, Associates who have been found to violate this
                    policy will be subject to disciplinary action, up to and
                    including termination.

               2.   Based on the nature of the violations, Associates may also
                    be prosecuted to the full extent of the law violated.
