Item 1.01. Entry into a Material Definitive Agreement.

      On February 8, 2005, the Board of Directors of Watts Water Technologies,
Inc. (the "Company") amended and restated the Watts Water Technologies, Inc.
Management Stock Purchase Plan (the "MSPP"). Several of the amendments to the
MSPP were made in order to bring the MSPP into compliance with Section 409A of
the Internal Revenue Code of 1986, as amended ("Section 409A"). The material
amendments are summarized below:

1.    Restricted Stock Units ("RSU's") that are awarded under the MSPP will now
      be valued on the third business day after the Company releases its
      year-end earnings.

2.    MSPP participants' elections to defer an annual bonus under the MSPP must
      now be made by December 31 of the year before the year in which the bonus
      will be earned, unless the bonus qualifies as "performance-based
      compensation" in which case the election must be made by June 30 of the
      year in which the bonus will be earned.

3.    MSPP participants will be permitted to make distribution election changes
      under the MSPP until December 31, 2005, however, beginning January 1,
      2006, MSPP participants will only be permitted to make election changes at
      least 12 months before a scheduled distribution from the MSPP and any such
      election change must extend the deferral period for a minimum of five
      years.

4.    The vesting schedule under the MSPP has been clarified to provide that
      vesting occurs incrementally over a three-year period.

5.    Distributions of amounts deferred under the MSPP may not be accelerated
      other than as permitted under Section 409A in connection with a "change in
      control" of the Company.

6.    There is now a six-month waiting period for distributions made to any "key
      employee" of the Company in connection with his or her termination of
      employment.

      The summary description of the MSPP is qualified in its entirety by
reference to the full text of the amended and restated MSPP as attached hereto
as Exhibit 10.1 and by this reference made a part hereof.

Item 1.01. Entry into a Material Definitive Agreement.

      On February 8, 2005, the Board of Directors of the Company amended and
restated the Watts Water Technologies, Inc. Executive Incentive Bonus Plan (the
"Bonus Plan"). Several of the amendments were made in order to change the goals
assigned to participants in the Bonus Plan and to change the method for
determining the percentage of a participant's maximum potential bonus percentage
to be received by such participant. The material amendments are summarized
below:

1.    A participant may now be assigned a subset of the economic value added
      goal, including without limitation a working capital objective or a cash
      flow objective.

2.    The inventory turns goal has been replaced with an earnings objective.

3.    In the event a participant achieves more than 100% of the target assigned
      to a bonus goal, that participant will be eligible to receive an
      additional bonus up to 200% of the percentage weight allocated to such
      bonus goal, up to a maximum of 200% of such participant's maximum
      potential bonus percentage.

      The summary description of the Bonus Plan is qualified in its entirety by
reference to the full text of the amended and restated Bonus Plan as attached
hereto as Exhibit 10.2 and by this reference made a part hereof.



Item 1.01. Entry into a Material Definitive Agreement.

      On February 8, 2005, the Board of Directors of the Company approved an
increase in the amount of the additional annual retainer payable to the Chair of
the Audit Committee from $5,000 to $10,000. A summary of the total compensation
payable to non-employee directors of the Company as determined by the Board of
Directors on May 4, 2004 and revised as described above on February 8, 2005 is
attached hereto as Exhibit 10.3 and by this reference made a part hereof.
