                           THE WATTS INDUSTRIES, INC.
                        1986 INCENTIVE STOCK OPTION PLAN

                                                                  April 24, 1986

     The purpose of this Plan is to encourage and enable certain employees of
Watts Industries, Inc. (the "Company") and/or of any subsidiary of the Company,
as defined in the Internal Revenue Code of 1954, as amended (the "Code"), to
acquire an interest in the Company through the granting of options, as herein
provided, to acquire its Common Stock, $1.00 par value (the "Common Stock"),
which are intended to qualify as incentive stock options under the provisions of
the Code.

1.   SHARES OF STOCK SUBJECT TO THE PLAN

     The stock that may be issued and sold pursuant to options granted under the
Plan shall not exceed, in the aggregate, 3,000 shares of Common Stock of the
Company, which may be (i) authorized but unissued shares, (ii) treasury shares
or (iii) shares previously reserved for issuance upon the exercise of options
under the Plan, which options have expired or been terminated; provided,
however, that the number of shares subject to the Plan shall be subject to
adjustment as provided in Section 6.

2.   ELIGIBILITY

     Options will be granted only to persons who are key employees of the
Company or a subsidiary (as defined in the Code) and eligible to receive an
incentive stock option under the Code.

<Page>

Directors of the Company or a subsidiary who are not employees thereof are not
eligible to receive options under the Plan. The Board of Directors of the
Company (the "Board") acting by a majority of its disinterested Directors, shall
determine the employees to be granted options ("Optionees"), the number of
shares subject to each option, and the terms of the options (including, without
limitation, such provisions as to vesting and/or restrictions upon transfer as
may be included in the incentive stock option agreements approved in connection
with the granting of options) consistently with the provisions of this Plan. The
Board may appoint from its disinterested Directors a committee of three or more
persons who may exercise the powers of the Board in granting options under the
Plan. As used herein, a "disinterested" Director shall mean one who is not
presently eligible, and has not been eligible at any time within one year prior
to the granting of the options in question, to receive any option granted under
the Plan or any stock, stock options or stock appreciation rights under any
other plan of the Company or its affiliates.

3.   PRICE AND LIMITATION ON GRANT OF OPTIONS

     The purchase price of shares which may be purchased under each option shall
be at least equal to the fair market value per share of the outstanding Common
Stock of the Company at the time the option is granted as determined by the
Board acting in good faith (provided, however, that the price of shares which
may be purchased under any option granted to any employee who

                                        2
<Page>

owns more than 10% of the total combined voting power of all classes of stock of
the Company shall be at least equal to 110% of the fair market value per share
of the outstanding Common Stock of the Company at the time the option is granted
as determined by the Board of Directors acting in good faith), and the Board in
its discretion may set a higher price. The aggregate fair market value
(determined as of the time the option is granted) of the stock for which an
individual may be granted incentive stock options in any calendar year under
this Plan and all other plans of the Company and any parent or subsidiary of the
Company ( as defined in the Code) shall not exceed $100,000 plus any "unused
limit carryover" as that term is defined in Section 422A of the Code.

4.   PERIOD OF OPTION AND CERTAIN LIMITATIONS ON RIGHT TO EXERCISE

     Each option shall be exercisable at such time or times as the Board shall
from time to time determine, but in no event after the expiration of ten years
from the date such option is granted (provided, however, that no option granted
to any employee who owns more than 10% of the total combined voting power of all
classes of stock of the Company shall be exercisable more than five years after
the date such option is granted). The delivery of certificates representing
shares under any option will be contingent upon receipt by the Company from the
Optionee (or a purchaser acting in his stead in accordance with the provisions
of the option) of the full purchase price for such shares and the fulfillment of
any other requirements contained in the option as determined by the Board of

                                        3
<Page>

Directors or under applicable provisions of law; and until such receipt of the
purchase price and fulfillment of other requirements no Optionee or person
entitled to exercise the option shall be, or shall be deemed to be, a holder of
any shares subject to the option for any purpose.

5.   NON-TRANSFERABILITY OF OPTION

     Each option granted under the Plan shall provide that it is personal to the
Optionee, is not transferable by the Optionee in any manner otherwise than by
will or the laws of descent and distribution and is exercisable, during the
Optionee's lifetime, only by him. However, the rights and obligations of the
Company under the Plan and any option may be assigned by the Company to a
successor to the whole or any substantial part of its business provided that
such successor assumes in writing all of such rights and obligations.

6.   DILUTION OR OTHER ADJUSTMENTS

     The terms of the options and the number of shares subject to this Plan
shall be equitably adjusted in such manner as to prevent dilution or enlargement
of option rights in the following instances:

          (a)  the declaration of a dividend payable to the holders of Common
               Stock in stock of the same class;

          (b)  a split-up of the Common Stock or a reverse split thereof;

          (c)  a recapitalization of the Company under which shares of one or
               more different classes of stock are distributed in exchange for
               or upon the Common Stock

                                        4
<Page>

               without payment of any valuable consideration by the holders
               thereof.

The terms of any such adjustment shall be conclusively determined by the Board.

7.   SHAREHOLDER APPROVAL.

     The Plan is subject to the approval of the shareholders of the Company, and
although options may be granted prior to such approval, none may be exercised
until shareholder approval has been obtained. If such approval is not given
within twelve months after the date hereof, the Plan and all outstanding options
shall terminate and be null and void.

8.   ADMINISTRATION AND AMENDMENT OF THE PLAN

     The Plan shall be administered by the Board, or a committee thereof as
provided in Section 2, which shall effect the grant of options under the Plan,
determine the form of options to be granted in each case, and make any other
determination under or interpretation of any provision of the Plan and any
option. Any of the foregoing actions taken by the Board or such committee shall
be final and conclusive. The Board may amend and make such changes in and
additions to the Plan as it may deem proper and in the best interest of the
Company; provided, however, that no such action shall adversely affect or impair
any options theretofore granted under the Plan without the consent of the
applicable Optionee; and provided further, however, that no amendment (i)
increasing the maximum number of shares which may be issued under the Plan,
except as provided in Section 6,

                                        5
<Page>

(ii) extending the term of the Plan or any option, (iii) changing the minimum
exercise price of options to be granted under the Plan, or (iv) changing the
requirements as to eligibility for participation in the Plan, shall be adopted
without the approval of shareholder.

9.   EXPIRATION AND TERMINATION OF THE PLAN

     Options may be granted under the Plan at any time, or from time to time,
within ten years from the date the Plan is adopted or the date on which it is
approved by the shareholders of the Company, whichever is earlier, as long as
the total number of shares purchased under the Plan and subject to outstanding
options under the Plan does not exceed 3,000 shares of the Common Stock of the
Company, subject to adjustment as provided in Section 6. The Plan may be
abandoned or terminated at any time by the Board, except with respect to any
options then outstanding under the Plan.
