ITEM 1.01   ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

      On December 5, 2005, Mueller Streamline China, LLC and Mueller Streamline
Holding, S.L. (together, the "Company's Subsidiaries"), subsidiaries of Mueller
Industries, Inc. (the "Company"), received a business license from a Chinese
industry and commerce authority, establishing a joint venture between the
Company's Subsidiaries, Jiangsu Xingrong Hi-Tech Co., Ltd. ("XR") and Jiangsu
Baiyang Industries Ltd. ("BY"). That certain Equity Joint Venture Agreement,
among the Company's Subsidiaries, XR and BY (the "JV Agreement"), provides for a
joint venture named Jiangsu Mueller-Xingrong Copper Industries Limited (the
"Joint Venture"), to design, market and manufacture commercial copper tube and
related products for air conditioning applications. It is anticipated that such
products will be marketed and sold primarily in the People's Republic of China,
as well as complement the Company's U.S. product line.

      Pursuant to the terms and conditions of the JV Agreement, the Company's
Subsidiaries will contribute to the Joint Venture approximately U.S. $19,400,000
in cash, and XR and BY will collectively contribute the equivalent of
approximately U.S. $19,015,841 in machinery, equipment, land use rights and
other assets. Upon the consummation of such contributions, the Joint Venture
will be owned 50.5% by the Company's Subsidiaries and 49.5% by XR and BY
together.

      Among other conditions, no party to the Joint Venture had any obligation
to make contributions to the Joint Venture until the Joint Venture received the
business license from the Chinese industry and commerce authority, which was
received on December 5, 2005.

      The Joint Venture shall be governed by a five member board of directors,
of which three members shall be elected by the Company, through the Company's
Subsidiaries and two members shall be elected by XR and BY together.
