Item 1.01 Entry into a Material Definitive Agreement

On April 1, 2011, Watts Water Technologies, Inc. (the "Company") and Watts Industries Deutschland GmbH, an indirect wholly-owned subsidiary of the Company ("Watts Germany"), entered into a share and asset sale and purchase agreement (the "Sale and Purchase Agreement") with Danfoss International A/S (the "Seller") and Danfoss A/S (the "Seller Parent"). Pursuant to the Sale and Purchase Agreement, Watts Germany will purchase all of the outstanding share capital (the "Danfoss Shares") of Danfoss Socla S.A.S., a wholly-owned subsidiary of the Seller ("Danfoss Socla"), and the related water controls business (the "Danfoss Assets") of entities controlled directly or indirectly by the Seller Parent (the Danfoss Shares, together with the Danfoss Assets, the "Danfoss Business"). Danfoss Socla is a manufacturer of water protection valves and flow control solutions for the water market and the heating, ventilation and air conditioning market. Danfoss Socla is based in France and its products are distributed worldwide for municipal, industrial, commercial and residential use. 

Under the terms of the Sale and Purchase Agreement, Watts Germany has the option, in its sole discretion on or before the later of (i) April 22, 2011 and (ii) the third business day after the date on which certain confirmatory due diligence is completed, to purchase certain assets of the Seller Parent's Shanghai affiliate (the "Shanghai Purchase Option"). If Watts Germany exercises the Shanghai Purchase Option, Watts Germany will pay an aggregate of EUR 120.0 million (approximately $170.0 million based on the current exchange rate of Euro to U.S. Dollars), subject to working capital and related adjustments, for the Danfoss Business. If Watts Germany does not exercise the Shanghai Purchase Option, Watts Germany will pay an aggregate of EUR 117.0 million (approximately $165.8 million based on the current exchange rate of Euro to U.S. Dollars), subject to working capital and related adjustments, for the Danfoss Business. The Company intends to fund the transaction with Euro-based borrowings under the Company’s credit facility and cash on hand.

The terms of the Sale and Purchase Agreement were determined on the basis of arm’s-length negotiations.  Neither the Company nor Watts Germany has previously had any material relationship with Danfoss Socla, the Seller or the Seller Parent.

The Sale and Purchase Agreement provides for customary representations, warranties and covenants by Watts Germany, the Company, the Seller and the Seller Parent, as well as a five-year non-compete and a two-year non-solicitation applicable to the Seller Parent and its affiliates.  Certain of the Seller’s and the Seller Parent’s indemnity obligations in favor of Watts Germany and the Company apply only with respect to aggregate liabilities in excess of specified thresholds, are subject to caps and are effective only for specified periods of time.  The consummation of the acquisition is subject to customary closing conditions.

A copy of the Sale and Purchase Agreement is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference as though fully set forth herein.  The foregoing summary of the Sale and Purchase Agreement and the transactions contemplated thereby is qualified in its entirety by the complete text of the Sale and Purchase Agreement.  The Sale and Purchase Agreement has been included to provide information regarding its terms.  It is not intended to provide any other factual information about the Company or the Danfoss Business.  Such information can be found in the public filings the Company makes with the Securities and Exchange Commission, which are available without charge at www.sec.gov and in the Investor Relations section of the Company’s website at www.wattswater.com.
