Item 1.01.    Entry into a Material Definitive Agreement

Approval of Annual Bonus Plan
-----------------------------

Effective as of December 26, 2004, Mueller Industries, Inc. (the "Company")
adopted, subject to the approval of the Company's stockholders, the Mueller
Industries, Inc. Annual Bonus Plan (the "Plan"). At the Company's 2005 Annual
Meeting of Stockholders on May 5, 2005 (the "2005 Annual Meeting"), the
Company's stockholders approved the Plan. The purpose of the Plan is to provide
annual performance-based bonus compensation to certain of the Company's
employees and to enable the Company to qualify bonuses it pays to executive
officers as "performance-based compensation" that will be fully deductible by
the Company, notwithstanding the $1,000,000 limit on deductible compensation
imposed on the Company by of Section 162(m) of the Internal Revenue Code of
1986, as amended, with respect to certain executive officers. The Company's
Chairman and Chief Executive Officer, and any other employee of the Company
chosen by the Company's Compensation Committee, are eligible to participate in
the Plan. To make an award under the Plan for any fiscal year, the Compensation
Committee of the Board of Directors must, no later than 90 days after the
beginning of such fiscal year, establish for each participant the performance
goals for the year and the amount, or formula for determining the amount, of
cash bonus to be paid to the participant based on achievement of the performance
goals for the year. The performance goals will consist of one or more targeted
levels of performance of the Company or any subsidiary, division or other unit
of the Company with respect to one or more of the following objective measures:
(a) pre-tax earnings; (b) earnings per share; (c) operating income; (d) net
sales; (e) total shareholder return; (f) net income; (g) funds from operations;
(h) funds from operations multiple; (i) earnings before interest expense, taxes,
depreciation and amortization ("EBITDA"); (j) pretax operating earnings after
interest expense and before bonuses, service fees and extraordinary or special
items; (k) operating margin; (l) return on equity; (m) return on capital; (n)
return on investment; (o) operating earnings; (p) working capital; (q) ratio of
debt to shareholders' equity; (r) market capitalization; (s) market
capitalization defined by the Company's line of credit; (t) growth in funds from
operations; (u) growth in net operating income; (v) return on invested capital;
(w) inventory levels or inventory turnover; (x) total net sales; (y) total gross
profit or total gross profit percentage; (z) operating cash flow or free cash
flow; (aa) economic value added; (bb) pre-interest and pre-tax expense return on
average invested capital, which may be expressed on a current value basis; (cc)
accounts receivable (measured in terms of days sales outstanding); (dd)
operating expenses; (ee) sales growth; (ff) profit before taxes or profit after
taxes less the Company's cost of capital; and/or (gg) net revenue. Any such
targets may relate to one or any combination of two or more of corporate groups,
units, divisions, affiliates or to individual performance. 2005 bonus awards
will be based on the achievement of EBITDA goals, excluding extraordinary items.
The maximum annual bonus that may be paid under the Plan to any participant in
any fiscal year is $2,500,000.


Amendments to the Karp and O'Hagan Employment Agreements.
---------------------------------------------------------

On February 17, 2005, the Board of Directors of the Company approved an
amendment to the Amended and Restated Employment Agreements between the Company
and Harvey Karp, Chairman of the Board, and William D. O'Hagan, Chief Executive
Officer (the "Karp Agreement" and the "O'Hagan Agreement," respectively), to
eliminate the annual discretionary




cash bonus to be paid to each executive and to provide that each executive shall
participate in the Plan. The effectiveness of these amendments was subject to
the approval of the Plan by the Company's stockholders at the 2005 Annual
Meeting. On May 5, 2005, the Company's stockholders approved the Plan and the
amendments became effective. The remaining terms and provisions of the Karp
Agreement and the O'Hagan Agreement remain unchanged and continue in full force
and effect.
