                          MUELLER INDUSTRIES, INC.
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 (Unaudited)

General

     Certain information and footnote disclosures normally included in
annual financial statements prepared in accordance with accounting
principles generally accepted in the United States have been condensed or
omitted.  Results of operations for the interim periods presented are not
necessarily indicative of results which may be expected for any other
interim period or for the year as a whole.  This quarterly report on Form
10-Q should be read in conjunction with the Company's Annual Report on Form
10-K, including the annual financial statements incorporated therein.

     The accompanying unaudited interim financial statements include all
normal recurring adjustments which are, in the opinion of management,
necessary to a fair statement of the results for the interim periods
presented.  The six-month period ended July 2, 2005 contained 27 weeks
while the six-month period ended June 26, 2004 contained 26 weeks.

Note 1 - Earnings per Common Share and Stock-Based Compensation

     Basic per share amounts have been computed based on the average number
of common shares outstanding.  Diluted per share amounts reflect the
increase in average common shares outstanding that would result from the
assumed exercise of outstanding stock options, computed using the treasury
stock method.

     The Company accounts for its stock-based compensation plans using the
intrinsic value method prescribed in Accounting Principles Board Opinion
(APB) No. 25, "Accounting for Stock Issued to Employees", and related
Interpretations.  No stock-based employee compensation expense is reflected
in net income because the exercise price of the Company's incentive
employee stock options equals the market price of the underlying stock on
the date of grant.  The following table illustrates the effect on net
income and earnings per share if the Company had applied the fair value
recognition provisions of Statement of Financial Accounting Standards
(SFAS) No. 123, "Accounting for Stock-Based Compensation", to stock-based
employee compensation.

Note 2 - Commitments and Contingencies

     The Company is involved in certain litigation as either plaintiff or
defendant as a result of claims that have arisen in the ordinary course of
business which management believes will not have a material effect on the
Company's financial condition or results of operations.







                                     -10-


     The Company has been named as a defendant in several purported class
action complaints brought by direct and indirect purchasers alleging
anticompetitive activities with respect to the sale of copper plumbing
tubes in the United States.  Two such purported class actions were filed in
the United States District Court for the Western District of Tennessee (the
Federal Actions), four were filed in the Superior Court of the State of
California, County of San Francisco (the California Actions), one was filed
in the Circuit Court for Shelby County, Tennessee (the Tennessee Action),
and one was filed in the Superior Court of the Commonwealth of
Massachusetts, County of Middlesex (the Massachusetts Action, and with the
Federal Actions, the California Actions and the Tennessee Action, the
Actions).  Wholly owned Company subsidiaries, WTC Holding Company, Inc.,
Deno Holding Company, Inc., and Mueller Europe Ltd. are named in all of the
Actions, and Deno Acquisition Eurl is named in two of the Actions.  All of
the Actions, which are similar, seek declaratory (except for the
Massachusetts Action) and monetary relief.  Plaintiffs' motions to
consolidate and for appointment of lead counsel in the Federal Actions and
plaintiffs' motion to consolidate the California Actions have been granted.
On July 6, 2005, a motion to dismiss the Federal Actions for failure to state
a claim was granted as to WTC Holding Company, Inc. and Deno Holding Company,
Inc. and denied as to Mueller Industries, Inc.  Mueller Europe's motion to
dismiss the Federal Actions for lack of personal jurisdiction is pending.
The Company has not yet been required to respond to the complaints in the
California, Tennessee, and Massachusetts Actions.  The Company believes that
the claims for relief in the Actions are without merit and intends to defend
the Actions vigorously.

     Guarantees, in the form of letters of credit, are issued by the
Company generally to guarantee the payment of insurance deductibles,
retiree health benefits, and certain operating costs of a foreign
subsidiary.  The terms of the Company's guarantees are generally one year
but are renewable annually as required.  The maximum potential amount of
future payments the Company could have been required to make under its
guarantees at July 2, 2005 was $10.4 million.

Note 3 - Impairment Charge

     During the first quarter of 2004, the Company recognized a $3.9
million impairment charge related to its subsidiary, Overstreet-Hughes Co.,
Inc., of which $2.3 million was goodwill and the remainder was property,
plant, and equipment.  The results of Overstreet-Hughes, which manufactures
tubular components and assemblies primarily for the original equipment
manufacturer (OEM) air-conditioning market, had not met expectations.
Furthermore, Overstreet-Hughes' primary customer announced the closure of
its facility that consumes the majority of Overstreet-Hughes' output.
Consequently, the Company reduced its carrying cost in these long-lived
assets to its best estimate of fair value.  This estimate was determined
based on a discounted cash flow method.

     The change in cumulative foreign currency translation adjustment
primarily relates to the Company's investment in its U.K., Mexican, and
Canadian subsidiaries and fluctuations in exchange rates between their
local currencies and the U.S. dollar.  During the first half of 2005, the
value of the British pound sterling decreased 8.1 percent compared to the
U.S. dollar, the value of the Canadian dollar decreased 0.9 percent
compared to the U.S. dollar, and the value of the Mexican peso increased
3.6 percent compared to the U.S. dollar.

     The Company previously disclosed in its financial statements for the
year ended December 25, 2004, that it expected to contribute approximately
$1.3 million to its pension plans and approximately $0.8 million to its
other postretirement benefit plans in 2005.  The Company now anticipates
contributions to its pension plans for the year to be approximately $2.4
million.  During the first six months of 2005, $1.2 million of
contributions have been made to certain pension plans and $0.4 million of
contributions have been made to other postretirement benefit plans.

Note 7 - Acquisitions and Investments

     On December 14, 2004, the Company acquired shares in seven companies
and inventory of another (collectively Mueller Comercial) for an aggregate
of $42.3 million, subject to closing adjustments, including $3.0 million
for a contingent earn-out payment held in escrow.  These operations include
pipe nipple manufacturing in Mexico and import distribution businesses
which product lines include malleable iron fittings and other plumbing
specialties.  The combined sales of Mueller Comercial are approximately $60
million annually.

     This acquisition was accounted for using the purchase method of
accounting.  The purchase price of Mueller Comercial has been preliminarily
allocated to the acquired assets based on their estimated fair market value
awaiting additional information including appraisals of long-lived assets.
Final allocations to the acquired assets and liabilities assumed, as well as
resolution of the contingent earn-out and the ultimate resolution of closing
adjustments to the purchase price, will result in future adjustments to
goodwill.

     During the first quarter of 2004 the Company recorded a $2.3 million
provision for certain federal income tax audit exposures related to the
Company's equity investment Conbraco Industries, Inc.  Upon resolution of
these matters in the second quarter of 2005, the Company reversed the
provision, which increased net income by approximately $1.5 million, or
4 cents per diluted share.

Note 8 - Recently Issued Accounting Standards

     In December 2004, the Financial Accounting Standards Board issued SFAS
No. 123(R), "Share-Based Payment", which is a revision of SFAS No. 123 and
supersedes APB No. 25.  SFAS No. 123(R) requires all share-based payments
to employees, including grants of employee stock options, to be valued at
fair value on the date of grant, and to be expensed over the applicable
vesting period.  Pro forma disclosure of the income statement effects of
share-based payments is no longer an alternative.  SFAS No. 123(R) provides
alternative methods of adoption which include prospective application and a
modified retroactive application.  The Company is currently evaluating the
financial impact, including the available alternatives of adoption, of SFAS
No. 123(R).  SFAS No. 123(R) also requires the benefits of tax deductions
in excess of recognized compensation cost to be reported as a financing
cash flow, rather than as an operating cash flow as required under current
literature.  This requirement will reduce net operating cash flows and
increase net financing cash flows in periods after adoption.  While the
Company cannot estimate what those amounts will be in the future (because
they depend on, among other things, when employees exercise stock options),


                                     -15-


the amount of operating cash flows recognized in the year ending December
25, 2004 for such excess tax deductions was $31.8 million.  The amount of
income tax benefit from exercise of stock options recognized in the first
half of 2005 and 2004 was $0.5 million and $9.7 million, respectively.  The
Company is required to adopt the provisions of SFAS No. 123(R) effective as
of the beginning of the first quarter of 2006.

Note 9 - Environmental Reserves

     The Company is subject to normal environmental standards imposed by
federal, state, local, and foreign environmental laws and regulations.  At
July 2, 2005, the Company had $9.2 million reserved for the environmental
remediation, post-closure monitoring, and related obligations.  The Company
periodically reassesses these amounts and estimates its obligations over
the foreseeable future based upon results on ongoing remediation and
monitoring programs, communications with regulatory agencies, and changes
in environmental law.  While additional costs are possible, the Company
believes that its reserve is adequate and amounts beyond that are not
reasonably estimable.  Costs of future expenditures for environmental
remediation obligations are not discounted to their present value.  Accrued
environmental liabilities are not reduced by potential insurance
reimbursements.  Based upon information currently available, management
believes that the outcome of pending environmental matters will not
materially affect the overall financial position and results of operations
of the Company.

Note 10 - Income Taxes

     The Company's effective tax rate for the first half of 2005 was 31.6
percent compared with 32.3 percent for the same period of last year.  The
current period rate is less than the expected federal rate due primarily to
income in foreign jurisdictions that is taxed at rates lower than the U.S.
federal rate and reductions to valuation reserves, totaling approximately
$1.2 million, related to the resolution of certain income tax exposures and
the recognition of U.K. net operating loss carryforwards.

Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations

General Overview

     Mueller Industries, Inc. is a leading manufacturer of copper tube and
fittings; brass and copper alloy rod, bar, and shapes; aluminum and brass
forgings; aluminum and copper impact extrusions; plastic fittings and
valves; refrigeration valves and fittings; and fabricated tubular products.
The Company also resells imported brass and plastic plumbing valves,
malleable iron fittings, steel nipples, faucets, and plumbing specialty
products.  Mueller's operations are located throughout the United States,
and in Canada, Mexico, and Great Britain.

     The Company's businesses are managed and organized into two segments:
Standard Products Division (SPD) and Industrial Products Division (IPD).
SPD manufactures and sells copper tube, copper and plastic fittings, and
valves.  Outside of the United States, SPD manufactures and sells copper
tube in Europe.  SPD sells these products to wholesalers in the HVAC
(heating, ventilation, and air-conditioning), plumbing, and refrigeration
markets, to distributors to the manufactured housing and recreational
vehicle industries, and to building material retailers.  IPD manufactures
and sells brass and copper alloy rod, bar, and shapes; aluminum and brass
forgings; aluminum and copper impact extrusions; refrigeration valves and
fittings; fabricated tubular products; and gas valves and assemblies.  IPD
sells its products primarily to original equipment manufacturers (OEMs),
many of which are in the HVAC, plumbing, and refrigeration markets.

     New housing starts and commercial construction are important
determinants of the Company's sales to the HVAC, refrigeration and plumbing
markets because the principal end use of a significant portion of the
Company's products is in the construction of single and multi-family
housing and commercial buildings.  Repairs and remodeling projects are also
important drivers of underlying demand for these products.

      Profitability of certain of the Company's product lines depends upon
the "spreads" between the cost of raw material and the selling prices of
its completed products.  The open market prices for copper cathode and
scrap, for example, influence the selling price of copper tubing, a
principal product manufactured by the Company.  The Company attempts to
minimize the effects on profitability from fluctuations in material costs
by passing through these costs to its customers.  The Company's earnings
and cash flow are dependent upon these spreads that fluctuate based upon
market conditions.

     Earnings and profitability are also subject to market trends such as
substitute products and imports.  Plastic plumbing systems are the primary
substitute product; these products represent an increasing share of
consumption.  Imports of copper tubing from Mexico have increased in recent
years, although U.S. consumption is still predominantly supplied by U.S.
manufacturers.

Results of Operations

     During the second quarter of 2005, the Company's net sales were $410.5
million, which compares with net sales of $380.8 million over the same
period of 2004.  Net sales were $812.2 million in the first half of 2005
compared with $726.8 million in the same period of 2004.  The increase in
net sales is attributable to higher selling prices and acquired businesses,
offset by lower volume.  The average price of copper was approximately 22
percent higher in the first half of 2005 compared with the same period of
2004.  During the second quarter of 2005, the Company's core manufacturing
businesses shipped 182.2 million pounds of product compared to 198.5
million pounds in the same quarter of 2004.  The Company shipped 371.6
million pounds of product in the first half of 2005 compared with 396.1
million in the same period of 2004.  This decrease was due primarily to
lower copper tube shipments.

     Cost of goods sold increased from $303.7 million in the second quarter
of 2004 to $345.7 million in the same period of 2005.  This increase was
primarily attributable to higher material costs.  Gross profit decreased to
$64.8 million from $77.1 million due primarily to lower shipments and lower
margins on copper tube.  Inventories valued using the LIFO method totaled
$33.4 million at July 2, 2005 and $36.5 million at December 25, 2004.  At
July 2, 2005 and December 25, 2004, the approximate FIFO cost of such
inventories was $67.7 million and $64.4 million, respectively.

     Depreciation and amortization expense was $10.4 million in the second
quarter of 2005 compared with $10.2 million during the second quarter of
2004.  Selling, general, and administrative expense was $29.1 million for
the second quarter of 2005 compared with $28.2 million for the same period
of 2004.  Year-to-date selling, general, and administrative expense was $59.5
million for 2005 compared with $54.9 million for the same period of 2004.
The increase is primarily attributable to businesses acquired in the latter
half of 2004.

     During the first quarter of 2004, the Company recognized a $3.9
million impairment charge related to its subsidiary, Overstreet-Hughes Co.,
Inc., of which $2.3 million was goodwill and the remainder was property,
plant, and equipment.  The results of Overstreet-Hughes, which manufactures
tubular components and assemblies primarily for the OEM air-conditioning
market, had not met expectations.  Furthermore, Overstreet-Hughes' primary
customer announced the closure of its facility that consumes the majority
of Overstreet-Hughes' output.  Consequently, the Company reduced its
carrying cost in these long-lived assets to its best estimate of fair value.
This estimate was determined based on a discounted cash flow method.

     For the second quarter of 2005, operating income at SPD was $23.2
million which compares with $37.2 million in the same period of 2004.  This
decrease is primarily attributable to reduced profitability in copper tube
as a result of lower volumes and narrowed spreads, partially offset by
contributions of acquired businesses.

     Operating income at IPD was $7.3 million in the second quarter of 2005
compared with $6.3 million in the second quarter of 2004.  Profitability
reductions in the brass rod business due to lower volumes and spreads were
offset by improvements in other product lines.


                                     -18-


     Interest expense for the second quarter of 2005 totaled $4.8 million,
compared with $0.2 million for the same period of 2004.  For the first half
of 2005, interest expense was $9.9 million compared with $0.4 million for
the same period of 2004.  The increase in the second quarter and first half
of 2005 is primarily attributable to the Subordinated Debentures issued as
part of the Special Dividend during the fourth quarter of 2004.

     Other income, net was $4.8 million for the first half of 2005 and $3.8
million for the same period of 2004.  During the first quarter of 2004, the
Company completed the sale of certain undeveloped land that resulted in
recognizing a gain of $5.2 million.  The proceeds realized from sale were
$5.2 million.  Also during the first quarter of 2004, the Company
recognized a $3.3 million loss related to its equity interest in Conbraco
Industries, Inc.  The loss related primarily to certain federal income tax
audit exposures of Conbraco that were assessed during the first quarter of
2004; Conbraco settled these matters in the second quarter of 2005 and,
consequently, the Company reversed a loss accrual that resulted in a $2.3
million gain.

     The Company's effective tax rate for the first half of 2005 was 31.6
percent compared with 32.3 percent for the same period of last year.  The
current period rate is less than the expected federal rate due primarily to
income in foreign jurisdictions that is taxed at rates lower than the U.S.
federal rate and reductions to valuation reserves, totaling approximately
$1.2 million, related to the resolution of certain income tax exposures and
the recognition of U.K. net operating loss carryforwards.  The lower rate in
the first quarter of 2004 is primarily attributable to the recognition of a
capital loss carryforward related to the sale of land that had a tax basis
significantly less than the realized proceeds.


Liquidity and Capital Resources

     Cash provided by operating activities in the first half of 2005
totaled $34.5 million, which is primarily attributable to net income,
depreciation and amortization, and an increase in liabilities partially
offset by increased receivables and increased inventories.  Fluctuations in
the cost of copper and other raw materials affect the Company's liquidity.
Changes in material costs directly impact components of working capital,
primarily inventories and accounts receivable.  During the first half of
2005, the average COMEX copper price was approximately $1.50 per pound,
which represents a 22 percent increase over the average price during the
first half of 2004.  This rise in the price of cathode has also resulted in
sharp increases in the open market price for copper scrap and, to a lesser
extent, the price of brass scrap.

     During the first half of 2005, cash used for investing activities was
$8.3 million, consisting primarily of $8.9 million for capital expenditures
reduced by $0.6 million proceeds from sales of properties.  The Company
also used $4.0 million for financing activities during the first half,
consisting primarily of the payment of dividends, partially offset by the
proceeds from stock option exercises.





                                     -19-


     During the first quarter of 2004, the Chairman of the Company's Board
of Directors, Mr. Harvey L. Karp, exercised options to purchase 900,000
shares of Company stock.  As provided in Mr. Karp's option agreement, the
Company withheld the number of shares, at their fair market value,
sufficient to cover the minimum withholding taxes incurred by the exercise.
These shares withheld have been classified as acquisition of treasury stock
on the Company's Consolidated Statement of Cash Flows.  The income tax
benefit of $9.7 million from the exercise of stock options was recognized
as a direct addition to additional paid-in-capital and, therefore, had no
effect on the Company's earnings.

     The Company has a $150 million unsecured line-of-credit (Credit
Facility) which expires in November 2007.  At July 2, 2005, there were no
outstanding borrowings under the Credit Facility.  Approximately $10.3
million in letters of credit were backed by the Credit Facility at the end
of the quarter.  At July 2, 2005 the Company's total debt was $315.2
million or 46 percent of its total capitalization.

     Covenants contained in the Company's financing obligations require,
among other things, the maintenance of minimum levels of working capital,
tangible net worth, and debt service coverage ratios.  At July 2, 2005, the
Company was in compliance with all of its debt covenants.

     The Company declared and paid a regular quarterly cash dividend of ten
cents per common share in the first and second quarters of 2005.  Payment
of dividends in the future is dependent upon the Company's financial
condition, cash flows, capital requirements, earnings, and other factors.
On May 1, 2005 the Company began making semi-annual interest payments of
approximately $9.2 million on its 6% Subordinated Debentures.

     Management believes that cash provided by operations and currently
available cash of $69.1 million will be adequate to meet the Company's
normal future capital expenditures and operational needs.  The Company's
current ratio was 2.5 to 1 at July 2, 2005.

     The Company's Board of Directors has authorized the repurchase until
October 2005 of up to ten million shares of the Company's common stock
through open market transactions or through privately negotiated
transactions.  The Company has no obligation to purchase any shares and may
cancel, suspend, or extend the time period for the purchase of shares at
any time.  Any purchases will be funded primarily through existing cash and
cash from operations.  The Company may hold any shares purchased in
treasury or use a portion of the repurchased shares for employee benefit
plans, as well as for other corporate purposes.  Through July 2, 2005, the
Company has repurchased approximately 2.4 million shares under this
authorization.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

     The Company is exposed to market risk from changes in raw material
costs, energy costs, and foreign currency exchange.  To reduce such risks,
the Company may periodically use financial instruments.  All hedging
transactions are authorized and executed pursuant to policies and
procedures.  Further, the Company does not buy or sell financial instruments
for trading purposes.

Cost and Availability of Raw Materials and Energy

     Copper and brass represent the largest component of the Company's
variable costs of production.  The cost of these materials is subject to
global market fluctuations caused by factors beyond the Company's control.
Significant increases in the cost of metal, to the extent not reflected in
prices for the Company's finished products, or the lack of availability
could materially and adversely affect the Company's business, results of
operations and financial condition.

     The Company occasionally enters into forward fixed-price arrangements
with certain customers.  The Company may utilize forward contracts to hedge
risks associated with forward fixed-price arrangements.  The Company may
also utilize forward contracts to manage price risk associated with
inventory.  Gains or losses with respect to these positions are deferred in
stockholders' equity as a component of comprehensive income and reflected
in earnings upon the sale of inventory.  Periodic value fluctuations of the
contracts generally offset the value fluctuations of the underlying fixed-
price transactions or inventory.  During the second quarter, the Company
entered into forward contracts to purchase approximately $1.1 million of
copper.  As of July 2, 2005, the Company held open forward contracts to
purchase approximately $1.2 million of copper through December 2005.

     Futures contracts may also be used to manage price risk associated
with natural gas purchases.  Gains and losses with respect to these
positions are deferred in stockholders' equity as a component of
comprehensive income and reflected in earnings upon consumption of natural
gas.  Periodic value fluctuations of the contracts generally offset the
value fluctuations of the underlying natural gas prices.  At July 2, 2005,
the Company had no open forward contracts to purchase natural gas.

Foreign Currency Exchange Rates

     Foreign currency exposures arising from transactions include firm
commitments and anticipated transactions denominated in a currency other
than an entity's functional currency.  The Company and its subsidiaries
generally enter into transactions denominated in their respective
functional currencies.  Foreign currency exposures arising from transactions
denominated in currencies other than the functional currency are not
material; however, the Company may utilize certain forward fixed-rate
contracts to hedge such transactional exposures.  Gains and losses with
respect to these positions are deferred in stockholders' equity as a
component of comprehensive income and reflected in earnings upon collection
of receivables.  At July 2, 2005, the Company had no open forward contract
to exchange foreign currency.



                                     -21-


     The Company's primary foreign currency exposure arises from foreign-
denominated revenues and profits and their translation into U.S. dollars.
The primary currencies to which the Company is exposed include the Canadian
dollar, the British pound sterling, the Euro, and the Mexican peso.  The
Company generally views as long-term its investments in foreign
subsidiaries with a functional currency other than the U.S. dollar.  As a
result, the Company generally does not hedge these net investments.


Item 4.  Controls and Procedures

     The Company maintains disclosure controls and procedures designed to
ensure information required to be disclosed in Company reports filed under
the Securities Exchange Act of 1934, as amended (the Exchange Act), is
recorded, processed, summarized, and reported within the time periods
specified in the Securities and Exchange Commission's rules and forms.
Disclosure controls and procedures are designed to provide reasonable
assurance that information required to be disclosed in Company reports
filed under the Exchange Act is accumulated and communicated to management,
including the Company's Chief Executive Officer and Chief Financial Officer,
as appropriate, to allow timely decisions regarding required disclosure.

     The Company's management, under the supervision and with the
participation of the Company's Chief Executive Officer and Chief Financial
Officer, has evaluated the effectiveness of the Company's disclosure
controls and procedures as of the end of the period covered by this report.
Based upon that evaluation, the Company's Chief Executive Officer and Chief
Financial Officer concluded that the disclosure controls and procedures are
effective.

     There were no changes in the Company's internal control over financial
reporting during the Company's fiscal quarter ending July 2, 2005, that
have materially affected, or are reasonably likely to materially affect,
the Company's internal control over financial reporting.

     The Company has identified deficiencies in the internal controls over
financial reporting of the business (currently known as Mueller Comercial)
acquired by the Company in December 2004.  While the Company's assessment
of these internal controls and procedures is continuing, at this time the
Company intends to change such controls by, among other things, (i)
preparing monthly financial statements on a timely basis, (ii) implementing
routine preventative and detective control procedures and (iii)
implementing additional disclosure controls and procedures.  In addition
to these modifications, accounting and finance staff resources will be
increased at these operations.  In light of the relative size and
magnitude of Mueller Comercial to the Company's consolidated financial
statements, the Company does not believe that the deficiencies identified
have materially affected, or are reasonably likely to materially affect,
the Company's internal control over financial reporting.

Part II.  Other Information

Item 1.  Legal Proceedings

Copper Tube Antitrust Litigation

     The Company has been named as a defendant in several purported class
action complaints brought by direct and indirect purchasers alleging
anticompetitive activities with respect to the sale of copper plumbing
tubes in the United States.  Two such purported class actions were filed in
the United States District Court for the Western District of Tennessee (the
Federal Actions), four were filed in the Superior Court of the State of
California, County of San Francisco (the California Actions), one was filed
in the Circuit Court for Shelby County, Tennessee (the Tennessee Action),
and one was filed in the Superior Court of the Commonwealth of
Massachusetts, County of Middlesex (the Massachusetts Action, and with the
Federal Actions, the California Actions and the Tennessee Action, the
Actions).  Wholly owned Company subsidiaries, WTC Holding Company, Inc.,
Deno Holding Company, Inc., and Mueller Europe Ltd. are named in all of the
Actions, and Deno Acquisition Eurl is named in two of the Actions.  All of
the Actions, which are similar, seek declaratory (except for the
Massachusetts Action) and monetary relief.  Plaintiffs' motions to
consolidate and for appointment of lead counsel in the Federal Actions and
plaintiffs' motion to consolidate the California Actions have been granted.
On July 6, 2005, a motion to dismiss the Federal Actions for failure to state
a claim was granted as to WTC Holding Company, Inc. and Deno Holding Company,
Inc. and denied as to Mueller Industries, Inc.  Mueller Europe's motion to
dismiss the Federal Actions for lack of personal jurisdiction is pending.
The Company has not yet been required to respond to the complaints in the
California, Tennessee, and Massachusetts Actions.  The Company believes that
the claims for relief in the Actions are without merit and intends to defend
the Actions vigorously.

Other Matters

     The Company is aware of investigations of competition in markets in
which it participates, or has participated in the past, in Europe and
Canada.  The Company has not been fined as a result of any such
investigations and does not anticipate any material adverse effect on its
business or financial condition as a result of those other investigations.
