not later than the 90th day of such year. Such Performance Goals may be
expressed in terms of one or more of the following: (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

have been met. Performance Goals may include a threshold level of performance
below which no Bonus payment shall be made, levels of performance at which
specified percentages of the target Bonus shall be paid, and a maximum level of
performance above which no additional Bonus shall be paid. The Performance Goals
established by the Committee may be (but need not be) different for each Plan
Year and different Performance Goals may be applicable to different
Participants.

     4.   Bonuses.
          --------

     a. In General. For each Plan Year commencing with the Plan Year ending
December 31, 2005, the Committee shall, no later than the ninety (90) days
following commencement of such Plan Year, specify the Performance Goals
applicable to such Plan Year and the amount of the target Bonus for each
Participant with respect to such Plan Year. A Participant's target Bonus for
each Plan Year shall be expressed as a dollar amount or as a percentage of such
Participant's base salary for such Plan Year, provided that, if expressed as a
percentage of a Participant's base salary, the amount of such base salary for
purposes of the Plan may not be increased for such Plan Year after the date on
which the target Bonus is so established. Payment of a Bonus for a particular
Plan Year shall be made only if and to the extent the Performance Goals with
respect to such Plan Year are attained and, unless otherwise provided by the
Committee in its discretion in connection with terminations of employment, if a
participant's employment with the Company terminates for any reason other than
death or Disability during any Plan Year, then the participant will immediately
cease participation in the Plan and will not have the opportunity to earn a
Bonus for such Plan Year. The foregoing notwithstanding, if a Participant's
employment with the Company terminates by reason of death or Disability during
any Plan Year, the Committee, in its sole discretion, may determine to pay all
or a prorated portion of any Bonus relating to the Plan Year in which the
Participant's employment terminates. Unless such a determination is made, upon a
participant's termination of employment on account of death or Disability, the
participant shall immediately cease participation in the Bonus Plan and shall
not be entitled to earn a Bonus for such Plan Year. The actual amount of a Bonus
payable under the Plan shall be determined as a percentage of the Participant's
target Bonus, which percentage may vary depending upon the extent to which the
Performance Goals have been attained and may be less than, greater than, or
equal to the target Bonus. The Committee may, in its discretion, reduce or
eliminate the amount payable to any Participant, in each case based upon such
factors as the Committee may deem relevant, but shall not increase the amount
payable to any Participant for any Plan Year.

     b. Limitation on Bonuses. Notwithstanding anything to the contrary
contained in this Plan, the maximum Bonus which may be earned by any Participant
under the Plan in respect of any Plan Year shall not exceed $2,500,000.

     c. Time of Payment. All payments in respect of Bonuses granted under this
Section 4 shall be made no later than two and one-half months following the end
of the Plan Year. In the case of Participants who are Covered Employees, unless
otherwise determined by the Committee in connection with terminations of
employment such payments shall be made only after achievement of the Performance
Goals has been certified by the Committee in writing.

     d. Form of Payment. Payment of a Participant's Bonus for any Plan Year
shall be made in cash.

     5.   Administration.
          ---------------

     The Plan shall be administered by the Committee. The Committee shall have
the authority in its sole discretion, subject to and not inconsistent with the
express provisions of the Plan, to administer the Plan and to exercise all the
powers and authorities either specifically granted to it under the Plan or
necessary or advisable in the administration of the Plan, including, without
limitation, the authority to grant Bonuses; to determine the persons to whom and
the

                                       3
<PAGE>

time or times at which Bonuses shall be granted; to determine the terms,
conditions, restrictions and performance criteria relating to any Bonus; to make
adjustments in the Performance Goals in response to changes in applicable laws,
regulations, or accounting principles to the extent not inconsistent with Code
Section 162(m) and the regulations thereunder; to the extent provided in Section
4(a) hereof, to reduce the compensation payable upon attainment of Performance
Goals; to construe and interpret the Plan and any Bonus; to prescribe, amend and
rescind rules and regulations relating to the Plan; and to make all other
determinations deemed necessary or advisable for the administration of the Plan.

     The Committee shall consist of two or more persons each of whom is an
"outside director" within the meaning of Code Section 162(m). The Committee may
appoint a chairperson and a secretary and may make such rules and regulations
for the conduct of its business as it shall deem advisable, and shall keep
minutes of its meetings. All determinations of the Committee shall be made by a
majority of its members either present in person or participating by conference
telephone at a meeting or by unanimous written consent. The Committee may
delegate to one or more of its members or to one or more agents such
administrative duties as it may deem advisable, and the Committee or any person
to whom it has delegated duties as aforesaid may employ one or more persons to
render advice with respect to any responsibility the Committee or such person
may have under the Plan. All decisions, determinations and interpretations of
the Committee shall be final and binding on all persons, including the Company,
the Participant (or any person claiming any rights under the Plan from or
through any Participant) and any shareholder.

     No member of the Board or the Committee shall be liable for any action
taken or determination made in good faith with respect to the Plan or any Bonus
granted hereunder.

     6.  General Provisions.
         -------------------

     a. Compliance with Legal Requirements. The Plan and the granting of
Bonuses, and the other obligations of the Company under the Plan shall be
subject to all applicable federal and state laws, rules and regulations, and to
such approvals by any regulatory or governmental agency as may be required.

     b. No Right To Continued Employment. Nothing in the Plan or in any Bonus
granted shall confer upon any Participant the right to continue in the employ of
the Company or any of its Subsidiaries or to be entitled to any remuneration or
benefits not set forth in the Plan or to interfere with or limit in any way the
right of the Company to terminate such Participant's employment.

     c. Withholding Taxes. The Company or Subsidiary employing any Participant
shall deduct from all payments and distributions under the Plan any taxes
required to be withheld by federal, state or local governments.

     d. Amendment and Termination of the Plan. The Board may at any time and
from time to time alter, amend, suspend, or terminate the Plan in whole or in
part; provided, however, that no amendment which requires shareholder approval
in order for the Plan to continue to comply with Code Section 162(m) shall be
effective unless the same shall be approved by the requisite vote of the
shareholders of the Company. Additionally, the Committee may make such
amendments as it deems necessary to comply with other applicable laws, rules and
regulations. Notwithstanding the foregoing, no amendment shall affect adversely
any of the rights of any Participant, without such Participant's consent, under
any Bonus theretofore granted under the Plan.

                                       4

<PAGE>

     e. Participant Rights. No Participant shall have any claim to be granted
any Bonus under the Plan, and there is no obligation for uniformity of treatment
among Participants.

     f. Unfunded Status of Bonuses. The Plan is intended to constitute an
"unfunded" plan for incentive compensation. With respect to any payments which
at any time are not yet made to a Participant pursuant to a Bonus, nothing
contained in the Plan or any Bonus shall give any such Participant any rights
that are greater than those of a general creditor of the Company.

     g. Governing Law. The Plan and the rights of all persons claiming hereunder
shall be construed and determined in accordance with the laws of the State of
Delaware without giving effect to the choice of law principles thereof.

     h. Effective Date. The Plan shall first be effective with respect to the
2005 Plan Year, but only if the Plan shall have been approved at the 2005 annual
meeting by the requisite vote approval of the shareholders of the Company.

     i. Interpretation. The Plan is designed and intended to comply with Code
Section 162(m), to the extent applicable, and all provisions hereof shall be
construed in a manner to so comply.

     j. Term. No Bonus may be granted under the Plan with respect to any Plan
Year after the Plan Year ending December 26, 2009, unless the Plan is reapproved
by the stockholders of the Company at the Company's 2010 Annual Meeting of
Stockholders. The Plan shall remain in effect until it has been terminated
pursuant to Section 6(d) hereof. The Plan must be reapproved by the stockholders
of the Company every five years in compliance with Treasury Regulation
1.162-27(e)(4)(vi).

                             SECOND AMENDMENT TO THE
                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT
                         DATED AS OF SEPTEMBER 17, 1997
                                     BETWEEN
                    HARVEY KARP AND MUELLER INDUSTRIES, INC.

     WHEREAS, Harvey Karp ("Executive") and Mueller Industries, Inc. (the
"Company") have entered into an Amended and Restated Employment Agreement
effective as of September 17, 1997, as amended on June 21, 2004, (the
"Agreement"); and

     WHEREAS, the parties now desire to amend the Agreement to eliminate the
discretionary cash bonus to be paid to the Executive each calendar year or part
thereof while the Executive is employed and provide that, in lieu thereof, the
Executive shall participate in the Company's performance-based Mueller
Industries, Inc. Annual Bonus Plan (the "Plan") while the Executive is employed.

     NOW, THEREFORE, in consideration of the promises and of the mutual
covenants herein contained, effective as of the date of the Company's 2005
Annual Meeting of Stockholders, the Agreement is hereby amended as follows (this
amendment is hereinafter referred to as the "Second Amendment").

     1. The text of Section 3(a)(ii) of the Agreement, is hereby deleted in its
entirety.

     2. Sections 3(b) and 3(c) are restated as Sections 3(c) and 3(d),
respectively, and a new Section 3(b) is added as follows:

        (b) The Executive shall be entitled to participate in the
        Company's Annual Bonus Plan (the "Bonus Plan") each year
        during which the Executive is employed and may be eligible to
        earn a performance-based cash bonus (a "Performance-Based
        Bonus") under the terms and conditions of such plan. Any
        Performance-Based Bonus and/or annual discretionary bonus
        earned, as applicable, by the Executive prior to
        implementation of the Bonus Plan is hereafter referred to as a
        "Bonus".

     3. Should the Company's stockholders fail to approve the Plan at the
Company's 2005 Annual Meeting of Stockholders on May 5, 2005, then the Plan
shall cease to be effective and this Second Amendment shall not take effect, and
the Agreement shall be deemed to remain unchanged and continue in full force and
effect.

     4. Except as expressly amended by this Second Amendment, the remaining
terms and provisions of the Agreement shall remain unchanged and continue in

which shall be deemed an original but all of which together shall constitute one

Second Amendment by its duly authorized representative and Executive has
executed this Second Amendment as of the 17th day of February, 2005.
