WATTS WATER TECHNOLOGIES, INC.

5,000,000 Shares of Class A Common Stock

Underwriting Agreement

November 15, 2006

Ladies and Gentlemen:

Watts Water Technologies, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule I hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”) and J.P. Morgan Securities Inc. (“JPMSI”) is acting as book-running manager, an aggregate of 5,000,000 shares (the “Firm Shares”) of the Company’s Class A Common Stock, par value $0.10 per share (the “Stock”) and, at the option of the Underwriters, up to an additional 750,000 shares (the “Option Shares”) of Stock.  The Firm Shares and the Option Shares are herein referred to as the “Shares.”

The Company hereby confirms its agreement with the several Underwriters as follows:

1.     Registration Statement.  The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-124615), including a prospectus (the “Basic Prospectus”), relating to the Stock and other securities to be issued from time to time by the Company, and has filed or transmitted for filing with, or shall promptly hereafter file or transmit for filing with, the Commission a prospectus

supplement specifically relating to the sale of the Shares pursuant to Rule 424 under the Securities Act.  Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement.”  If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement.  As used herein, the term “Prospectus” means the Basic Prospectus, as amended or supplemented, and as supplemented by the prospectus supplement specifically relating to the sale of the Shares in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Shares; and the term “Preliminary Prospectus” means the Basic Prospectus, as supplemented by each prospectus supplement specifically relating to the sale of the Shares, that omitted the Rule 430 Information or other information to be included upon pricing in a form of prospectus filed with the Commission pursuant to Rule 424 under the Securities Act.  Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein.  Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the time when sales of the Shares were first made (the “Time of Sale”), the Company had prepared the following information: a Preliminary Prospectus dated November 7, 2006 (including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 as of the Time of Sale), and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed in Schedule II hereto (collectively, with the pricing information set out in Schedule II hereto, the “Time of Sale Information”).

2.     Purchase of the Shares by the Underwriters. (a) On the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, the Company agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase from the Company, at a price per share of $38.10 (the “Purchase Price”), the number of Firm Shares

2

set forth opposite the name of such Underwriter in Schedule I hereto under the heading “Number of Firm Shares to Be Purchased,” subject to adjustment in accordance with Section 10 and subject to adjustment among the Underwriters as JPMSI in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

In addition, the Company agrees to issue and sell the Option Shares to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Shares at the Purchase Price.  If any Option Shares are to be purchased, the number of Option Shares to be purchased by each Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Firm Shares set forth opposite the name of such Underwriter in  Schedule I hereto (or such number increased as set forth in Section 10) bears to the aggregate number of Firm Shares being purchased from the Company by the several Underwriters, subject, however, to such adjustments to eliminate any fractional shares as JPMSI in its sole discretion shall make.

The Underwriters may exercise the option to purchase the Option Shares at any time (but not more than once) on or before the thirtieth day following the date of this Agreement, by written notice from JPMSI to the Company.  Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date but shall not be earlier than the Closing Date nor later than the tenth full business day after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 10).  Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(b)  The Company understands that the Underwriters intend to make a public offering of the Shares as soon after the effectiveness of this Agreement as in the judgment of JPMSI is advisable, and initially to offer the Shares on the terms set forth in the Time of Sale Information and the Prospectus.  The Company acknowledges and agrees that the Underwriters may offer and sell Shares to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Shares purchased by it to or through any Underwriter.

(c)  Payment for the Shares shall be made by wire transfer in immediately available funds to the account specified by the Company to JPMSI against delivery of such Shares for the respective accounts of the several Underwriters through the facilities of The Depository Trust Company, with any transfer taxes payable in connection therewith duly paid by the Company.  The closing with respect to the Firm Shares shall be at the offices of Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017, at 10:00 A.M. New York City time on November 21, 2006, or at such other time or place on the same or such

3

other date, not later than the fifth business day thereafter, as JPMSI and the Company may agree upon in writing.  The closing with respect to any Option Shares shall be at the offices of Davis Polk & Wardwell on the date and at the time and place specified by JPMSI in the written notice of the Underwriters’ election to purchase such Option Shares.  The time and date of such payment for the Firm Shares is referred to herein as the “Closing Date,” and the time and date for such payment for any Option Shares, if other than the Closing Date, is herein referred to as the “Additional Closing Date.”

Notwithstanding the foregoing, in the event that JPMSI elects to take delivery of any Shares in certificated form, payment for such Shares shall be made to the Company against delivery to JPMSI for the respective accounts of the several Underwriters of such Shares in definitive form registered in such names and in such denominations as JPMSI shall request in writing not later than two full business days prior to the Closing Date (in the case of the Firm Shares) or the Additional Closing Date (in the case of the Option Shares) with any transfer taxes payable in connection with the sale of such Shares duly paid by the Company, and the certificates for such Shares will be made available for inspection and packaging by JPMSI at the office of JPMSI set forth above not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(d)  The Company acknowledges and agrees that each of JPMSI, the Representatives and the Underwriters is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Shares and the other transactions contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person.  Additionally, neither JPMSI, any Representative nor any Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction.  The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and JPMSI, the Representatives and the Underwriters shall have no responsibility or liability to the Company with respect thereto.  Any review by JPMSI, the Representatives or the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of JPMSI, the Representatives and the Underwriters and shall not be on behalf of the Company.

(r)    Title to Intellectual Property.  The Company and its subsidiaries own or possess sufficient trademarks, trade names, patent rights, copyrights, domain names, licenses, approvals, trade secrets and other similar rights (collectively, “Intellectual Property Rights”) reasonably necessary to conduct their businesses as now conducted; and the expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Change.  Neither the Company nor any of its subsidiaries has received any notice of infringement or conflict with asserted Intellectual Property Rights of others, which infringement or conflict, if the subject of an unfavorable decision, would result in a Material Adverse Change.  The Company is not a party to or bound by any options, licenses or agreements with respect to the Intellectual Property Rights of any other person or entity that are required to be set forth in the Time of Sale Information and the Prospectus and are not described in all material respects.  None of the technology employed by the Company has been obtained or is being used by the Company in violation of any contractual obligation binding on the Company or, to the Company’s knowledge, any of its officers, directors or employees or otherwise in violation of the rights of any persons except for such violations as would not, individually or in the aggregate, result in a Material Adverse Change.

(w)  Compliance With Environmental Laws.  Except as otherwise disclosed in the Time of Sale Information and the Prospectus or as would not, individually or in the aggregate, result in a Material Adverse Change (i) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign law or regulation relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including without limitation, laws and regulations relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum and petroleum products (collectively, “Materials of Environmental Concern”), or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Materials of Environment Concern (collectively, “Environmental Laws”), which violation includes, but is not limited to, noncompliance with any permits or other governmental authorizations required for the operation of the business of the Company or its subsidiaries under applicable Environmental Laws, or noncompliance with the terms and conditions thereof; (ii) neither the Company nor any of its subsidiaries has received

12

any written communication, whether from a governmental authority, citizens group, employee or otherwise, that alleges that the Company or any of its subsidiaries is in violation of any Environmental Law; (iii) there is no claim, action, cause of action, investigation, proceeding, summons, request for information or written notice alleging potential liability arising under or in connection with any Environmental Laws, including, without limitation, those for investigatory costs, cleanup costs, governmental responses costs, natural resources damages, property damages, personal injuries, attorneys’ fees or penalties (collectively, “Environmental Claims”), pending or, to the best of the Company’s knowledge, threatened against the Company or any of its subsidiaries or any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law; and (iv) to the best of the Company’s knowledge, there are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release, emission, discharge, presence or disposal of any Material of Environmental Concern, that reasonably could result in a violation of any Environmental Law or form the basis of a potential Environmental Claim against the Company or any of its subsidiaries or against any person or entity whose liability for any Environmental Claim the Company or any of its subsidiaries has retained or assumed either contractually or by operation of law.

(x)    Costs of Environmental Compliance.  Except as otherwise disclosed in the Time of Sale Information and the Prospectus, there are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, individually or in the aggregate, result in a Material Adverse Change.

(y)   Compliance With ERISA.  The Company and its Significant Subsidiaries and any “employee benefit plan” (as defined under Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its Significant Subsidiaries or their “ERISA Affiliates” (as defined below) during the past three years are in compliance in all material respects with ERISA and all other law applicable to such plans.  “ERISA Affiliate” means, with respect to the Company or its Significant Subsidiaries, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or any such Significant Subsidiary is a member.  No “reportable event” (as defined under Section 4043 of ERISA), other than an event for which the notice

requirement is waived, has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its Significant Subsidiaries or any of their ERISA Affiliates during the past three years.  No “employee benefit plan” established or maintained by the Company, its Significant Subsidiaries or any of their ERISA Affiliates during the past three years has any accumulated funding deficiency (as defined under Section 302 of ERISA).  Neither the Company, its Significant Subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code, which has not been satisfied prior to the date hereof.  To the knowledge of the Company, each “employee benefit plan” established or maintained by the Company, its Significant Subsidiaries or any of their ERISA Affiliates during the past three years that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

(z)    Disclosure Controls.  The Company maintains an effective system of “disclosure controls and procedures” (as defined in Rule 13a-15(e) of the Exchange Act) that is designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, including controls and procedures designed to ensure that such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding required disclosure.  The Company has carried out evaluations of the effectiveness of its disclosure controls and procedures as required by Rule 13a-15 of the Exchange Act.

(aa) Accounting Controls.  The Company maintains a system of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that complies with the requirements of the Exchange Act and has been designed by, or under the supervision of, its principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, including, but not limited to internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorizations; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken

14

with respect to any differences.  The Company is not aware of any material weakness in its internal control over financial reporting.

(bb) Insurance.  Each of the Company and its Significant Subsidiaries are insured by recognized, financially sound and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for their businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and its Significant Subsidiaries against theft, damage, destruction, and acts of terrorism or vandalism.  The Company has no reason to believe that it or any of its Significant Subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Change.  Neither the Company nor any of its Significant Subsidiaries has been denied any insurance coverage which it has sought or for which it has applied.

(cc) No Unlawful Payments.  Neither the Company nor any of its Significant Subsidiaries nor, to the best of the Company’s knowledge, any employee or agent of the Company or any of its Significant Subsidiaries, has made any contribution or other payment to any official of, or candidate for, any federal, state or foreign office in violation of any law or of the character required to be disclosed in the Time of Sale Information and the Prospectus.

(dd) No Restrictions on Subsidiaries.  Except as disclosed in the Registration Statement, the Time of Sale Information and the Prospectus, no subsidiary of the Company is currently prohibited, directly or indirectly, under any agreement or other instrument to which it is a party or is subject, from paying any dividends to the Company, from making any other distribution on such subsidiary’s capital stock, from repaying to the Company any loans or advances to such subsidiary from the Company or from transferring any of such subsidiary’s properties or assets to the Company or any other subsidiary of the Company.

(ee) No Broker’s Fees.  There is no broker, finder or other party that is entitled to receive from the Company any brokerage or finder’s fee or other fee or commission as a result of any transactions contemplated by this Agreement.

(ff)   No Registration Rights.  No person has the right (which has not been waived) to require the Company or any of its subsidiaries to register any securities for sale under the Securities Act by reason of the filing of the Registration Statement with the Commission or the issuance of the Shares and the sale of the Shares.

15

(gg) No Stabilization.  The Company has not taken, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Shares.

(hh) Related Party Transactions.  There are no business relationships or related-party transactions involving the Company or any of its Significant Subsidiaries or any other person required to be described in the Time of Sale Information and the Prospectus which have not been described as required.

(ii)   Compliance with Sarbanes-Oxley Act.  The Company and its directors and officers, in their capacities as such, are in compliance in all material respects with the applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes-Oxley Act”), including Section 402 related to loans and Sections 302 and 906 related to certifications.

(jj)   The Company is not an ineligible issuer and is a well-known seasoned issuer, in each case as defined under the Securities Act, in each case at the times specified in the Securities Act in connection with the offering of the Shares.

4.     Further Agreements of the Company.  The Company covenants and agrees with each Underwriter that:

(a)   Required Filings.  The Company will file the final Prospectus with the Commission within the time periods specified by Rule 424(b) and Rule 430A, 430B, or 430C under the Securities Act, will file any Issuer Free Writing Prospectus to the extent required by Rule 433 under the Securities Act, and will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Shares; and the Company will furnish copies of the Prospectus and each Issuer Free Writing Prospectus (to the extent not previously delivered) to the Underwriters in New York City prior to 10:00 A.M., New York City time, on the business day next succeeding the date of this Agreement in such quantities as the Representatives may reasonably request.

(b)   Delivery of Copies.  The Company will deliver, without charge, (i) to the Representatives, four conformed copies of the Registration Statement as originally filed and each amendment thereto, in each case excluding all exhibits and consents filed therewith and documents incorporated by reference therein; and (ii) during the Prospectus Delivery

16

Period, as many copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) as the Representatives may reasonably request.  As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters a prospectus relating to the Shares is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Shares by any Underwriter or dealer.

(c)   Amendments, Supplements and Issuer Free Writing Prospectuses.  Before preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement or the Prospectus, the Company will furnish to the Representatives and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement to which the Representatives reasonably object.

(d)   Notice to the Representatives.  The Company will advise the Representatives promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective; (ii) when any supplement to the Prospectus or any Issuer Free Writing Prospectus or any amendment to the Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (v) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Information or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; and (vi) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration

17

Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e)   Ongoing Compliance.  (i)  If during the Prospectus Delivery Period (A) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (B) it is necessary to amend or supplement the Prospectus to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law and (ii) if at any time prior to the Closing Date (A) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances, not misleading or (B) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(f)    Blue Sky Compliance.  The Company will qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Shares; provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

18

(g)   Earning Statement.  The Company will make generally available to its security holders and the Representatives as soon as practicable an earning statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the “effective date” (as defined in Rule 158) of the Registration Statement.

(h)   Clear Market.  For a period of 90 days after the date of the initial public offering of the Shares, the Company will not (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Stock or any securities convertible into or exercisable or exchangeable for Stock or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Stock or such other securities, in cash or otherwise, without the prior written consent of JPMSI, other than (A) the Shares, (B) the grant of options or other rights to purchase shares of Stock under existing employee stock option plans or employee stock purchase plans, and (C) any shares of Stock of the Company issued upon the exercise of options or other rights granted under existing employee stock option plans.  Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

(i)    Use of Proceeds.  The Company will apply the net proceeds from the sale of the Shares as described in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Use of Proceeds.”

(j)    No Stabilization.  The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Shares.

(k)   Reports.  So long as the Shares are outstanding, to the extent not otherwise available on EDGAR (as defined in Regulation S-T), the Company will furnish to the Representatives, as soon as they are available, copies of all reports or other communications (financial or other) furnished

19

to holders of the Shares, and copies of any reports and financial statements furnished to or filed with the Commission or any national securities exchange or automatic quotation system.

(l)    Record Retention.  The Company will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

5.     Certain Agreements of the Underwriters.  Each Underwriter hereby represents and agrees that:

(a)   It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 under the Securities Act, (ii) any Issuer Free Writing Prospectus listed in Schedule II hereto or prepared pursuant to Section 3(c) or Section 4(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”).

(b)   It is not subject to any pending proceeding under Section 8A of the Securities Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the Prospectus Delivery Period).

6.     Conditions to the Obligations of the Underwriters.  The several obligations of each of the Underwriters to purchase the Firm Shares on the Closing Date and the Option Shares, if any, on the Additional Closing Date, are subject to the accuracy, as of the Closing Date or each Additional Closing Date, as the case may be, of the representations and warranties of the Company contained herein, and to the performance by the Company of its covenants and other obligations hereunder and to the following additional conditions:

the Securities Act) and in accordance with Section 4(a); and all requests by the Commission for additional information shall have been complied with to the reasonable satisfaction of the Representatives.

(c)   No Downgrade.  Subsequent to the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded any securities or preferred stock of or guaranteed by the Company or any of its subsidiaries by any “nationally recognized statistical rating organization,” as such term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act and (ii) no such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its rating of any securities or preferred stock of or guaranteed by the Company or any of its subsidiaries (other than an announcement with positive implications of a possible upgrading).

(d)   No Material Adverse Change.  No event or condition of a type described in Section 3(g) hereof shall have occurred or shall exist, which event or condition is not described in the Time of Sale Information (excluding any amendment or supplement thereto) and the Prospectus (excluding any amendment or supplement thereto) and the effect of which in the judgment of JPMSI makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

(e)   Officer’s Certificate.  The Representatives shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, a certificate of the chief financial officer or chief accounting officer of the Company and one additional senior executive officer of the Company who is satisfactory to the Representatives (i) confirming that such officers have carefully reviewed the Registration Statement, the Time of Sale Information and the Prospectus and, to the best knowledge of such officers, the representations set forth in Sections 3(b) and 3(d) hereof are true and correct, (ii) confirming that the other representations and warranties of the Company in this Agreement are true and correct and that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at

21

(f)    Comfort Letters.  On the date of this Agreement and on the Closing Date or the Additional Closing Date, as the case may be, KPMG LLP shall have furnished to the Representatives at the request of the Company, letters, dated the respective dates of delivery thereof and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus; provided, that the letter delivered on the Closing Date or the Additional Closing Date, as the case may be shall use a “cut-off” date no more than three business days prior to such Closing Date or such Additional Closing Date, as the case may be.

(g)   Opinion of Counsel for the Company.  Wilmer Cutler Pickering Hale and Dorr LLP, counsel for the Company, shall have furnished to the Representatives at the request of the Company, their written opinion, dated the Closing Date or the Additional Closing Date, as the case may be, and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives, to the effect set forth in Exhibit A hereto.

(j)    No Legal Impediment to Issuance.  No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date or the Additional Closing Date, as the case may be, prevent the issuance or sale of the Firm Shares or the Option Shares, as the case may be; and no injunction or order

22

of any federal, state or foreign court shall have been issued that would, as of the Closing Date or the Additional Closing Date, as the case may be, prevent the issuance or sale of the Firm Shares or the Option Shares, as the case may be.

(k)   Good Standing.  The Representatives shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, satisfactory evidence of the good standing of the Company, Watts Regulator Co. and Anderson-Barrows Metals Corporation in their respective jurisdictions of organization and their good standing as foreign entities in such other jurisdictions as the Representatives may reasonably request, in each case in writing or any standard form of telecommunication from the appropriate Governmental Authorities of such jurisdictions.

7.     Indemnification and Contribution.

(a)   Indemnification of the Underwriters.  The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue

23

statement of a material fact contained in the Registration Statement, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through JPMSI expressly for use therein, it being understood and agreed that the only such information consists of the information relating to the Underwriters described as such in paragraph (b) below.

(b)   Indemnification of the Company.  Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through JPMSI expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following:  (i) the names and corresponding share amounts set forth in the table of Underwriters beneath the first paragraph under the caption “Underwriting” in the Prospectus; (ii) the second paragraph of text under such table, concerning the concession and reallowance figures; (iii) the paragraph of text beginning with the phrase “A prospectus supplement in electronic format . . .” under the caption “Underwriting” in the Prospectus; and (iv) the two paragraphs of text beginning with the phrase “In connection with this offering, the underwriters may engage in stabilizing transactions . . .” under the caption “Underwriting” in the Prospectus.

(c)   Notice and Procedures.  If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above,

24

such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 7.  If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of counsel related to such proceeding, as incurred.  In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred.  Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by JPMSI and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company.  The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment.  Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have

25

requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement.  No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)   Contribution.  If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares.  The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

26

(e)   Limitation on Liability.  The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above.  The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim.

(f)    Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(g)   Non-Exclusive Remedies.  The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8.     Effectiveness of Agreement.  This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9.     Termination.  This Agreement may be terminated in the absolute discretion of JPMSI, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (a) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (b) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (c) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; (d) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of JPMSI, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and

27

in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus, or (e) the representation in Section 3(b) is incorrect in any respect.

10.   Defaulting Underwriter.  (a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company on the terms contained in this Agreement.  If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms.  If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non defaulting Underwriters or the Company may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes.  As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule I hereto that, pursuant to this Section 10, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b)           If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)           If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Option Shares on the Additional Closing Date, as the case may be, shall terminate

28

without liability on the part of the non-defaulting Underwriters.  Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 and except that the provisions of Section 7 shall not terminate and shall remain in effect.

(d)           Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11.   Payment of Expenses.  (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the fees and expenses of the Company’s counsel and independent accountants; (iv) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (v) the cost of preparing stock certificates; (vi) the costs and charges of any transfer agent and any registrar; (vii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the NASD; (viii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) all expenses and application fees related to the listing of the Shares on the New York Stock Exchange.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Shares for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Shares for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12.   Persons Entitled to Benefit of Agreement.  This Agreement shall inure to the benefit of and be binding upon the parties hereto, and their respective successors and the officers and directors and any controlling persons referred to in Section 7.  Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.  No purchaser of Shares

29

from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13.   Survival.  The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14.   Certain Defined Terms.  For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

15.   Miscellaneous.  (a)  Authority of JPMSI.  Any action by the Representatives or the Underwriters hereunder may be taken by JPMSI on behalf of the Representatives and the Underwriters, and any such action taken by JPMSI shall be binding upon the Representatives and the Underwriters.

(c)           Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(d)           Counterparts.  This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

(e)           Amendments or Waivers.  No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

5.               The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

6.               The Registration Statement has been declared effective under the Securities Act, and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose are pending before or threatened by the Commission.

7.               Except as may be required under the Securities Act and the rules and regulations of the Commission thereunder and the Exchange Act and the rules and regulations of the Commission thereunder, no filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any United States federal or Massachusetts state governmental authority or agency is necessary for the issuance, sale and delivery of the Shares by the Company to the Underwriters pursuant to the Underwriting Agreement.

8.               The execution and delivery of the Underwriting Agreement by the Company and the consummation by the Company of the transactions contemplated thereby will not (a) conflict with or constitute a breach of any of the terms or provisions of, or a default under, the Certificate of Incorporation or By-laws of the Company or any agreement listed on Exhibit I hereto, or (b) to our knowledge, violate or conflict with any United States federal or Massachusetts state law, rule or regulation that in our experience is normally applicable in transactions of the type contemplated by the Underwriting Agreement, the Delaware General Corporation Law statute, or any judgment, order or decree specifically naming the Company or any Significant Subsidiary of which we are aware.

9.               The statements in the Time of Sale Information and the Prospectus (a) under the caption “Description of Class A Common Stock,” (b) in the first two sentences of the Risk Factor entitled “Certain indebtedness may limit our ability to pay dividends, incur additional debt and make acquisitions and other investments,” (c) in the third through sixth sentences of the Risk Factor entitled “Conversion and sale of a significant number of shares of our Class B common stock could adversely affect the market price of our Class A common stock” and (d) in the first sentence of the Risk Factor entitled “Our Class A common stock has insignificant voting power,” insofar as such statements constitute matters of law or legal conclusions or summarize the terms of agreements, are correct in all material respects.

The foregoing opinions are provided to you, as Representatives of the Underwriters, as a legal opinion only and not as a guaranty or warranty of the matters discussed herein.  These opinions are based upon currently existing statutes, rules, regulations and judicial decisions and are rendered as of the date hereof, and we disclaim any obligation to advise you of any change in any of the

2

foregoing sources of law or subsequent developments in law or changes in facts or circumstances that might affect any matters or opinions set forth herein.

In addition to the opinions provided above, we confirm to you as follows:  In the course of acting as counsel for the Company in connection with the preparation of the Registration Statement, the Time of Sale Information and the Prospectus, we have participated in conferences with officers and other representatives of the Company, representatives of and counsel for the Underwriters and representatives of the registered independent public accounting firm of the Company, during which the contents of the Registration Statement, the Time of Sale Information and the Prospectus were discussed.  While the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such that we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information or the Prospectus (except to the extent expressly set forth in paragraph 9 above), subject to the foregoing and based on such participation and discussions:

(a)                                  the Registration Statement, as of its effective date (including the information, if any, deemed pursuant to Rule 430A, 430B or 430C to be part of the Registration Statement at the time of effectiveness), the Prospectus, as of the date thereof, and the documents incorporated by reference into the Prospectus, when they became effective or were filed with the Commission (except for the financial statements, including the notes and schedules thereto, and other financial and accounting data included therein or omitted therefrom, as to which we express no view), appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act or the Exchange Act, as the case may be, and the applicable rules and regulations of the Commission thereunder;

(b)                                 no facts have come to our attention that have caused us to believe that (i) the Registration Statement, as of its effective date (including the information, if any, deemed pursuant to Rule 430A, 430B or 430C to be part of the Registration Statement at the time of effectiveness), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading (except as set forth in the parenthetical in clause (a) above), (ii) the Time of Sale Information, as of the Time of Sale, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except as set forth in the parenthetical in clause (a) above) or (iii) the Prospectus, as of its date or as of the date hereof, contained or contains an untrue statement

3

of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except as set forth in the parenthetical in clause (a) above); and

(c)                                  we are not aware of any action, proceeding or litigation pending, contemplated or threatened against the Company before any court or governmental or administrative agency or body that is required by the Securities Act or the rules and regulations thereunder to be described in the Registration Statement or the Prospectus that is not so described.

Exhibit B

Form of Opinion of the Company’s General Counsel

1.               All of the outstanding shares of Stock have been duly authorized and validly issued, are fully paid and non-assessable and, to my knowledge, have been issued in compliance with the registration and qualification requirements of federal securities laws.

2.               The description of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted and exercised thereunder, set forth in the Registration Statement, the Time of Sale Information and the Prospectus accurately summarizes in all material respects the information with respect to such plans, arrangements, options and rights, in each case insofar as such statements constitute summaries of matters of law or legal conclusions.

3.               To my  knowledge, neither the Company nor any Significant Subsidiary is in violation of its charter or by-laws or is in Default in the performance or observance of any obligation, agreement, covenant or condition contained in any material Existing Instrument, except in each such case for such violations or Defaults as would not, singly or in the aggregate, result in a Material Adverse Change.

4.               To my knowledge and other than as set forth in the Time of Sale Information and the Prospectus, there are no legal or governmental actions, suits or proceedings pending or threatened relating to environmental or discrimination matters which would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change.  To my knowledge, there is no existing or threatened or pending material labor dispute with the employees of the Company or any of its Significant Subsidiaries.

5.               To my knowledge, the descriptions of the Existing Instruments, and references thereto, contained in the Time of Sale Information and the Prospectus, in each case insofar as such statements constitute summaries of matters of law or legal conclusions, are accurate summaries in all material respects.

6.               To my knowledge, the Company and each Significant Subsidiary possess such valid and current certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct in all material respects their respective businesses, and, to my knowledge, neither the Company nor any Significant Subsidiary has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit which would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change.

To my knowledge, the Company and its subsidiaries own or possess sufficient Intellectual Property Rights reasonably necessary to conduct their business as now conducted; and the expected expiration of any of such Intellectual Property Rights would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change.  To my knowledge, neither the Company nor any of its Significant Subsidiaries has received any written notice of infringement or conflict with asserted Intellectual Property Rights of others, which would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change.  To my knowledge, the Intellectual Property Rights of the Company and each of its Significant Subsidiaries do not infringe or conflict with the asserted Intellectual Property Rights of others in a way which would, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change.  The Company is not a party to or bound by any options, licenses or agreements with respect to the Intellectual Property Rights of any other person or entity that are required to be set forth in the Time of Sale Information and the Prospectus and are not described in all material respects.  To my knowledge, none of the technology employed by the Company has been obtained or is being used by the Company in violation of any contractual obligation binding on the Company or any of its officers, directors or employees or otherwise in violation of the rights of any persons.

Form of Lock-Up Agreement

November 15, 2006

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Watts Water Technologies, Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule I to the Underwriting Agreement (the “Underwriters”), of shares of Class A Common Stock, $0.10 per share par value (together with the Class B Common Stock, $0.10 per share par value, the “Common Stock”), of the Company.  Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Common Stock, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of J.P. Morgan Securities Inc. on behalf of the Underwriters, the undersigned will not, during the period ending 90 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of,

directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.  In addition, the undersigned agrees that, without the prior written consent of J.P. Morgan Securities Inc. on behalf of the Underwriters, it will not, during the period ending 90 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.  Notwithstanding the foregoing, the executive officers and directors of the Company shall be entitled to sell, in the aggregate, up to 400,000 shares of Common Stock during the 90-day restricted period (including such period as it may be extended pursuant to the next paragraph).

Notwithstanding the paragraph above, if (1) during the last 17 days of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed by this Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement.  All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, the undersigned shall be released form all obligations under this Letter Agreement.  The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.
