EXHIBIT 99.5

                                AMENDMENT TO THE

                            MUELLER INDUSTRIES, INC.

                             2002 STOCK OPTION PLAN

     WHEREAS, the Board of Directors of Mueller Industries, Inc. (the "Company")
has resolved to amend the Company's 2002 Stock Option Plan (the "Plan") to
clarify that the anti-dilution adjustment language of Section 7(a) of the Plan
includes the authority to make adjustments for extraordinary dividends declared
on the Company's common stock, par value $0.01 per share, whether payable in the
form of cash, stock or any other form of consideration;

     NOW, THEREFORE, the Plan is hereby amended as follows (this amendment is
hereinafter referred to as the "Amendment"):

     1. The first sentence of Section 7(a) of the Plan, entitled Adjustment Upon
Changes in Capitalization, is hereby replaced in its entirety by the following:

          "In the event that (i) the outstanding shares of Common Stock or
          capital structure of the Company are changed by reason of
          reorganization, merger, consolidation, recapitalization,
          reclassification, stock split, reverse stock split, combination or
          exchange of shares and the like, or dividends payable in shares of
          Common Stock, or (ii) an extraordinary dividend is declared by the
          Company on the Common Stock, whether payable in the form of cash,
          stock or any other form of consideration (including debentures), the
          Committee shall make such appropriate adjustment to the aggregate
          number of shares of Common Stock available under the Plan, the number
          of shares of Common Stock subject to Options that may be granted to
          any person in any one year, and the number of shares of Common Stock
          and price per share of Common Stock subject to outstanding Options, as
          determined by the Committee, in its sole discretion, to be
          appropriate."

     2. Except as expressly amended by this Amendment, the remaining terms and
provisions of the Plan shall remain unchanged and continue in full force and
effect.

     IN WITNESS WHEREOF, the Company has caused its name to be ascribed to this
Amendment by its duly authorized representative as of the 1st day of September,
2004.

                                          MUELLER INDUSTRIES, INC.
