                                                                  EXECUTION COPY

                  RESTRICTED STOCK AGREEMENT (this "Agreement") made as of this
22nd day of November, 2002 (the "Effective Date"), National Waterworks Holdings,
a Delaware corporation (the "Company"), and Edward E. Maczko, Jr. (the
"Executive"). Certain capitalized terms used herein are defined in Section 6
hereof and capitalized terms used herein and not otherwise defined shall have
the meanings ascribed to them in the Executive Restricted Stock Agreement (as
defined below).

                  In consideration of the mutual covenants contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

                  1.       PURCHASE AND SALE OF EXECUTIVE STOCK.

                  (a)      Upon execution of this Agreement and in connection
with the Closing, the Executive Subscription Agreement and payment of the
Original Purchase Price (as hereinafter defined), the Company will issue to the
Executive 23,794.90 shares of Class A Common Stock, par value $0.01 per share,
of the Company (the "Class A Common Stock"), for a purchase price of $0.0179 per
share (the "Original Purchase Price"). All of such shares of Common Stock
purchased by the Executive hereby are referred to herein as "Executive Stock."
To secure the Company's rights under the Repurchase Option in Section 3, the
Company will retain possession of the certificates representing the Executive
Stock.

                  (b)      The parties agree that the Fair Market Value of each
share of Executive Stock as of the date hereof is $0.0179. The Executive, in his
sole discretion, may make an effective election with the Internal Revenue
Service (the "IRS") under Section 83(b) of the Code and the regulations
promulgated thereunder in the form of EXHIBIT A attached hereto. The Executive
understands that under applicable law such election must be filed with the IRS
no later than thirty (30) days after any acquisition of the Executive Stock to
be effective. If the Executive files an effective election, the excess of the
Fair Market Value of the Executive Stock (which the IRS may assert is different
from the Fair Market Value determined by the parties) covered by such election
over the amount paid by the Executive for the stock shall be treated as ordinary
income received by the Executive, and the Company or its subsidiary, National
Waterworks, Inc. shall withhold from Executive's compensation all amounts
required under applicable law. If the Executive does not file an effective
election, future appreciation on the Executive Stock will generally be taxable
as ordinary income when such stock vests pursuant to this Agreement. The
foregoing is merely a brief summary of complex tax laws and regulations, and
therefore, the Executive is strongly advised to consult with his own tax
advisors.

                  (c)      In connection with the acquisition of the Executive
Stock hereunder, the Executive represents and warrants to the Company that:

                           (i)     the Executive Stock to be acquired by the
         Executive pursuant to this Agreement will be acquired for the
         Executive's own account, for

<PAGE>

         investment only and not with a view to, or intention of, distribution
         thereof in violation of the Securities Act, or any applicable state
         securities laws, and the Executive Stock will not be disposed of in
         contravention of the Securities Act or any applicable state securities
         laws or this Agreement or the Stockholders' Agreement;

                           (ii)    the Executive is a manager of the Company's
         subsidiary, National Waterworks, Inc., and has generally such knowledge
         and experience in business and financial matters and with respect to
         investments in securities of privately held companies so as to enable
         him to understand and evaluate the risks and benefits of his investment
         in the Executive Stock;

                           (iii)   the Executive has no need for liquidity in
         his investment in the Executive Stock and is able to bear the economic
         risk of his investment in the Executive Stock for an indefinite period
         of time and understands that the Executive Stock has not been
         registered or qualified under the Securities Act or any applicable
         state securities laws, by reason of the issuance of the Executive
         Stock in a transaction exempt from the registration and qualification
         requirements of the Securities Act or such state securities laws and,
         therefore, cannot be sold unless subsequently registered or qualified
         under the Securities Act or such state securities laws or an exemption
         from such registration or qualification is available;

                           (iv)    the Executive understands that the exemption
         from registration afforded by Rule 144 (the provisions of which are
         known to the Executive) promulgated under the Securities Act, depends
         on satisfaction of various conditions and that, if applicable, Rule 144
         may only afford the basis for sales under certain circumstances and
         only in limited amounts; and

                           (v)     the Executive has had an opportunity to ask
         questions and receive answers concerning the terms and conditions of
         the offering of the Executive Stock and has had full access to or been
         provided with such other information concerning the Company as he has
         requested.

                  (d)      This Agreement constitutes the legal, valid and
binding obligation of the Executive, enforceable in accordance with its terms,
and the execution, delivery and performance of this Agreement by the Executive
does not and will not conflict with, violate or cause a breach of any agreement,
contract or instrument to which the Executive is a party or any judgment, order
or decree to which the Executive is subject. Upon your execution of this
Agreement, (i) the Executive represents that the Executive is not bound by any
employment contract, restrictive covenant or other restriction preventing the
Executive from entering into employment with or carrying out your
responsibilities for National Waterworks, Inc., or which is in any way
inconsistent with the terms of this Agreement; and (ii) the Executive and the
Company agree to terminate that certain Employment Security Agreement dated on
or about April 18, 2002 by and between the Executive and U.S. Filter
Distribution, Inc. ("Distribution") which has been assigned to the Company's
subsidiary, National Waterworks, Inc. The Company's issuance of the

<PAGE>

Executive Stock is contingent upon the execution of this Agreement
and the Company's standard Employee Noncompeition, NonDisclosure, and
Developments Agreement attached hereto as Exhibit B.

                  (e)      As an inducement to the Company to issue the
Executive Stock to the Executive and as a condition thereto, the Executive
acknowledges and agrees that:

                           (i)     neither the issuance of the Executive
         Stock to the Executive nor any provision contained herein shall
         entitle the Executive to remain in the employment of the Company and
         its Subsidiaries, if any, or affect the right of the Company to
         terminate the Executive's employment at any time for any reason; and

                           (ii)    except as provided in any other agreement
         between the Company and/or National Waterworks, Inc. and the Executive,
         the Company shall have no duty or obligation to disclose to the
         Executive, and the Executive shall have no right to be advised of, any
         material information regarding the Company and its Subsidiaries, if
         any, at any time prior to, upon or in connection with the forfeiture of
         the Executive Stock upon the termination of the Executive's employment
         with National Waterworks, Inc.

                  (f)      In connection with the issuance and sale by the
Company to the Executive of the Executive Stock, the Company represents and
warrants that:

                           (i)     the Company is a corporation duly organized,
         validly existing and in good standing under the laws of the
         jurisdiction of its incorporation and has all requisite corporate power
         and authority to own, lease and operate the assets used in its
         business, to carry on its business as presently conducted, to enter
         into this Agreement, to perform its obligations hereunder, and to
         consummate the transactions contemplated hereby;

                           (ii)    the Company has taken all corporate action
         necessary to authorize its execution and delivery of this Agreement,
         its performance of its obligations thereunder, and its consummation of
         the transactions contemplated thereby;

                           (iii)   this Agreement constitutes a valid and
         binding obligation of the Company, enforceable in accordance with its
         terms; and

                           (iv)    the Executive Stock, when issued in
         accordance with this Agreement, will be duly authorized and validly
         issued, fully paid and nonassessable and will be free of all
         Encumbrances created by or through the Company. For purposes of this
         clause, "Encumbrance" means any security interest, mortgage, lien,
         pledge, charge, easement, reservation, restriction, or similar right
         of any third party.

         "Vesting Date") as to that number of shares of the Executive Stock set
         forth opposite such Vesting Date:

</TABLE>

                           (ii)    Performance-Based Vesting - EBITDA. Six and
         one-quarter percent (6.25%) of the Executive Stock shall vest on each
         December 31st, commencing on December 31, 2003 and ending on December
         31, 2006 (each, a "Performance Vesting Date") provided that the Company
         generates EBITDA for such calendar year in an amount equal to the
         Minimum EBITDA set forth below. Notwithstanding the foregoing, in the
         event that the Company exceeds the Minimum EBITDA in any successor
         calendar year ending on or prior to December 31, 2006, the amount of
         such excess may be applied to any prior year in which the Company's
         EBITDA was less than the Minimum EBITDA for such year and, to the
         extent that adding such excess results in the Company's EBITDA for such
         period to exceed the Minimum EBITDA for such year, the Executive Stock
         subject to vesting on the last date of such year shall be deemed
         vested. Notwithstanding the foregoing, in the event that the Company
         exceeds the Minimum EBITDA in any calendar year ending on or prior to
         December 31, 2005, up to $5,000,000 of such excess may be applied to
         the Company's EBITDA for the calendar year immediately following such
         year only if the Company's EBITDA for such immediately following year
         is less than the Minimum EBITDA for such year and, to the extent that
         adding up to $5,000,000 of such excess results in the Company's EBITDA
         for such immediately following year to exceed the Minimum EBITDA for
         such year, the Executive Stock subject to vesting on the last date of
         such year shall be deemed vested.

</TABLE>

The Minimum EBITDA targets set forth above shall be appropriately adjusted by
the Company's Board of Directors for acquisitions made by the Company (whether
by purchase of assets, merger or otherwise) and such adjustments shall take into
account the pro forma annual EBITDA of any acquired business. For purposes of
clarity, EBITDA calculations shall not be reduced by the amounts paid by the
Company under that certain Management Agreement by and among the Company, J.P.
Morgan Partners, LLC and THL Managers V, LLC dated November 22, 2002.

                           (iii)   Performance-Based Vesting - Net Working
         Capital Percentage. Six and one-quarter percent (6.25%) of the
         Executive Stock shall vest on each December 31st, commencing on
         December 31, 2003 and ending on December 31, 2006 (each, a
         "Performance Vesting Date") provided that the Company achieves a Net
         Working Capital Ratio (as defined below) for such calendar year not to
         exceed the Maximum Net Working Capital Ratio set forth below.

by the Company's Board of Directors in the event that the Company acquires any
business(es) with an aggregate purchase price in excess of $10,000,000
(including any earnout components, etc.).

         "Net Working Capital Ratio" shall equal the simple average of the
Monthly Net Working Capital Ratios (as defined below) during such calendar year.
The "Monthly Net Working Capital Ratios" shall equal a fraction, the numerator
of which is the Net Working Capital (as defined below) calculated on the last
day of such calendar month, and the denominator of which is the product of
twelve (12) and the Net Sales (calculated in accordance with past practice)
generated by the Company during such calendar month. "Net Working Capital" shall
mean the excess of (i) the sum of the Company's accounts receivables and
inventory over (ii) the Company's accounts payable, each as calculated in
accordance with past practice.

<PAGE>

                  (b)      In the event the Executive ceases to be employed by
the Company or any of its Subsidiaries for any reason, then (i) all shares of
Executive Stock subject to clause (a)(i) above shall cease vesting effective as
of the Termination Date and, (ii) in the event that the Company achieves Minimum
EBITDA and/or achieves a Net Working Capital Ratio not to exceed the Maximum Net
Working Capital Ratio, as the case may be, with respect to the year in which
such termination occurs, the shares of Executive Stock subject to vesting with
respect to such year under clauses (a)(ii) or (a)(iii) multiplied by a fraction,
the numerator of which shall equal the number of whole months during such year
that the Executive remained employed with the Company and the denominator of
which is 12, shall be deemed vested as of the end of such year.

                  (c)      Notwithstanding the vesting terms set forth in clause
(a) above, upon a Termination Without Cause within twelve (12) months after the
consummation of a Sale, all Executive Stock subject to vesting pursuant to
clause (a)(i) above shall automatically and immediately vest.

                  (d)      Notwithstanding the vesting terms set forth in clause
(a) above, upon a Sale or Public Sale in which each of J.P Morgan Partners, LLC
and Thomas H. Lee Partners, L.P. and their affiliates receive aggregate
consideration or proceeds representing an amount which equals or exceeds the sum
of the amounts originally paid by J.P. Morgan Partners, LLC and Thomas H. Lee
Partners, L.P. and/or their affiliates with respect to the purchase of the
Company's equity securities on or about the Closing plus a rate of return on
such amounts equal to at least 25%, compounded annually, all Executive Stock
subject to vesting pursuant to clauses (a)(ii) and (a)(iii) shall automatically
and immediately vest.

                  (e)      Notwithstanding the vesting terms set forth in
clause (a) above, upon a Termination Without Cause within the first twelve (12)
months after the date hereof, 1.0417% of the Executive Stock for each whole
month that the Executive remained employed with the Company or its Subsidiary
shall automatically and immediately vest.

                  (f)      Notwithstanding the vesting terms set forth in
clause (a) above, if the Executive remains employed with the Company or any of
its Subsidiaries from the Effective Date through the eighth anniversary of the
Effective Date, all Executive Stock subject to vesting pursuant to clauses
(a)(ii) and (a)(iii) shall automatically and immediately vest on the eighth
anniversary of the Effective Date.

                  3.       REPURCHASE OF SHARES.

                  (a)      In the event that the Executive ceases to be
employed by the Company or any of its Subsidiaries for any reason, then all
shares of Executive Stock (whether held by the Executive or by one or more of
the Executive's transferees) which as of the date of termination:

                  (i)      have not vested pursuant to Section 2 hereof, will be
         subject to repurchase by the Company, at its option (the "Non-Vested
         Repurchase

<PAGE>

         Option"), for the lower of the Original Purchase Price of
         the Executive Stock and Fair Market Value

                  (ii)     have vested pursuant to Section 2 hereof, will be
         subject to repurchase, solely in the event that the Executive ceases
         to be employed by the Company or any of its Subsidiaries as a result
         of a Termination for Cause, by the Company, at its option (the "Vested
         Repurchase Option"), for the lower of Original Purchase Price of the
         Executive Stock and Fair Market Value.

                  (b)      In the event of Sale, then all shares of Executive
Stock (whether held by the Executive or by one or more of the Executive's
transferees) which, as of the date of such Sale, have not vested pursuant to
Sections 2(a)(ii) and (a)(iii) hereof, will be subject to repurchase by the
Company, at its option (the "Non-Vested Sale Repurchase Option"; and together
with the Non-Vested Repurchase Option and the Vested Repurchase Option, the
"Repurchase Option"), for the lower of the Original Purchase Price of the
Executive Stock and Fair Market Value.

                  (c)      The Repurchase Option shall be exercised by the
Company, or its designee, by delivering to the Executive a written notice of
exercise and a check in the amount of the Original Purchase Price or Fair Market
Value, as determined in accordance with Sections 3(a) and (b) above. Upon
delivery of such notice and payment of the purchase price as described above,
the Company, or its designee, shall become the legal and beneficial owner of the
shares of Executive Stock being repurchased and all rights and interest therein
or related thereto, and the Company, or its designee, shall have the right to
transfer to its own name the number of shares of Executive Stock being
repurchased without further action by the Executive or any of his transferees.
If the Company or its designee elect to exercise the repurchase rights pursuant
to this Section 3 and the Executive or his transferee fails to deliver the
shares of Executive Stock in accordance with the terms hereof, the Company, or
its designee, may, at its option, in addition to all other remedies it may have,
deposit the purchase price in an escrow account administered by an independent
third party (to be held for the benefit of and payment over to the Executive or
his transferee in accordance herewith), whereupon the Company shall by written
notice to the Executive cancel on its books the certificates(s) representing
such shares of Executive Stock registered in the name of the Executive and all
of the Executive's or his transferee's right, title, and interest in and to such
shares of Executive Stock shall terminate in all respects.

                  (d)      Each holder of the Executive Stock shall promptly
return to the Company share certificates representing shares of the Executive
Stock repurchased pursuant to Sections 3(a) and (b) hereof. In the event such
certificates represent more shares of the Executive Stock than are required to
be forfeited, the Company shall, without charge, deliver to such holder of the
Executive Stock a new certificate representing such excess.

                  (e)      In the event that Executive Stock is repurchased
pursuant to this Section 3, the Executive and his successors, assigns or
Representatives shall take (at the Company's expense) all steps necessary and
desirable to obtain all required third-party,

<PAGE>

governmental and regulatory consents and approvals and take all other
actions necessary and desirable to facilitate consummation of such
repurchase in a timely manner.

Executive Stock and by the Stockholders' Agreement as an Other Stockholder. Any
Transfer or attempted Transfer of any Executive Stock in violation of the
preceding sentence shall be void, and the Company shall not record such Transfer
on its books or treat any purported transferee of such Executive Stock as the
owner of such stock for any purpose.

                  (c)      The Executive agrees that so long as the Executive
owns shares of Executive Stock which have not vested pursuant to Section 2
hereof, the Executive shall be obligated to vote all of his, her or its shares
of Executive Stock which have not vested pursuant to Section 2 hereof in the
same manner and proportions as the votes cast by the holders of the Company's
voting capital stock not subject to such repurchase rights. If the Executive
fails or refuses to vote his, her or its shares of Executive Stock which have
not vested pursuant to Section 2 hereof as required by, or votes his, her or its
shares of Executive Stock which have not vested pursuant to Section 2 hereof in
contravention of this Section 5(c), then the Executive hereby grants to each of
the President and Treasurer of the Company, acting solely in his or her capacity
as such, an irrevocable proxy, coupled with an interest, to vote such shares in
accordance with Section 5(c).

jurisdiction in which enforcement is sought. Accordingly, if any particular
provision of this Agreement shall be adjudicated by a court of competent
jurisdiction to be invalid, prohibited or unenforceable for any reason, such
provision, as to such jurisdiction, shall be ineffective, without invalidating
the remaining provisions of this Agreement or affecting the validity or
enforceability of this Agreement or affecting the validity or enforceability of
such provision in any other jurisdiction. Notwithstanding the foregoing, if such

other jurisdiction.

under this Agreement shall not be assignable except in connection with a
permitted transfer of Executive Stock hereunder.

                  (e)      Governing Law. THIS AGREEMENT WILL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING
EFFECT TO ANY CHOICE OF LAW OR CONFLICTS PROVISION OR RULE (WHETHER OF THE STATE
OF DELAWARE, OR ANY OTHER JURISDICTION), THAT WOULD CAUSE THE LAWS OF ANY
JURISDICTION OTHER THAN THE STATE OF DELAWARE TO BE APPLIED. IN FURTHERANCE OF
THE FOREGOING, THE INTERNAL LAW OF THE STATE OF NEW YORK WILL CONTROL THE
INTERPRETATION AND CONSTRUCTION OF THIS AGREEMENT, EVEN IF UNDER SUCH
JURISDICTION'S CHOICE OF LAW OR CONFLICT OF LAW ANALYSIS, THE SUBSTANTIVE LAW OF
SOME OTHER JURISDICTION WOULD ORDINARILY APPLY.

PROCESS REQUIRED BY ANY SUCH COURT SHALL CONSTITUTE VALID AND LAWFUL SERVICE OF

specifically to recover damages and costs (including reasonable attorney's fees)

                            /s/ Edward E. Maczko, Jr.

                                                                  EXECUTION COPY

                  RESTRICTED STOCK AGREEMENT (this "Agreement") made as of this
22nd day of November, 2002 (the "Effective Date"), National Waterworks Holdings,
a Delaware corporation (the "Company"), and Ron Hood (the "Executive"). Certain
capitalized terms used herein are defined in Section 6 hereof and capitalized
terms used herein and not otherwise defined shall have the meanings ascribed to
them in the Executive Restricted Stock Agreement (as defined below).

                  In consideration of the mutual covenants contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

                  1.       PURCHASE AND SALE OF EXECUTIVE STOCK.

                  (a)      Upon execution of this Agreement and in connection
with the Closing, the Executive Subscription Agreement and payment of the
Original Purchase Price (as hereinafter defined), the Company will issue to the
Executive 23,794.90 shares of Class A Common Stock, par value $0.01 per share,
of the Company (the "Class A Common Stock"), for a purchase price of $0.0179 per
share (the "Original Purchase Price"). All of such shares of Common Stock
purchased by the Executive hereby are referred to herein as "Executive Stock."
To secure the Company's rights under the Repurchase Option in Section 3, the
Company will retain possession of the certificates representing the Executive
Stock.

                  (b)      The parties agree that the Fair Market Value of each
share of Executive Stock as of the date hereof is $0.0179. The Executive, in his
sole discretion, may make an effective election with the Internal Revenue
Service (the "IRS") under Section 83(b) of the Code and the regulations
promulgated thereunder in the form of EXHIBIT A attached hereto. The Executive
understands that under applicable law such election must be filed with the IRS
no later than thirty (30) days after any acquisition of the Executive Stock to
be effective. If the Executive files an effective election, the excess of the
Fair Market Value of the Executive Stock (which the IRS may assert is different
from the Fair Market Value determined by the parties) covered by such election
over the amount paid by the Executive for the stock shall be treated as ordinary
income received by the Executive, and the Company or its subsidiary, National
Waterworks, Inc. shall withhold from Executive's compensation all amounts
required under applicable law. If the Executive does not file an effective
election, future appreciation on the Executive Stock will generally be taxable
as ordinary income when such stock vests pursuant to this Agreement. The
foregoing is merely a brief summary of complex tax laws and regulations, and
therefore, the Executive is strongly advised to consult with his own tax
advisors.

                  (c)      In connection with the acquisition of the Executive
Stock hereunder, the Executive represents and warrants to the Company that:

                           (i)     the Executive Stock to be acquired by the
         Executive pursuant to this Agreement will be acquired for the
         Executive's own account, for

<PAGE>

         investment only and not with a view to, or intention of, distribution
         thereof in violation of the Securities Act, or any applicable state
         securities laws, and the Executive Stock will not be disposed of in
         contravention of the Securities Act or any applicable state securities
         laws or this Agreement or the Stockholders' Agreement;

                           (ii)    the Executive is a manager of the Company's
         subsidiary, National Waterworks, Inc., and has generally such knowledge
         and experience in business and financial matters and with respect to
         investments in securities of privately held companies so as to enable
         him to understand and evaluate the risks and benefits of his investment
         in the Executive Stock;

                           (iii)   the Executive has no need for liquidity in
         his investment in the Executive Stock and is able to bear the economic
         risk of his investment in the Executive Stock for an indefinite period
         of time and understands that the Executive Stock has not been
         registered or qualified under the Securities Act or any applicable
         state securities laws, by reason of the issuance of the Executive
         Stock in a transaction exempt from the registration and qualification
         requirements of the Securities Act or such state securities laws and,
         therefore, cannot be sold unless subsequently registered or qualified
         under the Securities Act or such state securities laws or an exemption
         from such registration or qualification is available;

                           (iv)    the Executive understands that the exemption
         from registration afforded by Rule 144 (the provisions of which are
         known to the Executive) promulgated under the Securities Act, depends
         on satisfaction of various conditions and that, if applicable, Rule 144
         may only afford the basis for sales under certain circumstances and
         only in limited amounts; and

                           (v)     the Executive has had an opportunity to ask
         questions and receive answers concerning the terms and conditions of
         the offering of the Executive Stock and has had full access to or been
         provided with such other information concerning the Company as he has
         requested.

                  (d)      This Agreement constitutes the legal, valid and
binding obligation of the Executive, enforceable in accordance with its terms,
and the execution, delivery and performance of this Agreement by the Executive
does not and will not conflict with, violate or cause a breach of any
agreement, contract or instrument to which the Executive is a party or any
judgment, order or decree to which the Executive is subject. Upon your
execution of this Agreement, (i) the Executive represents that the Executive is
not bound by any employment contract, restrictive covenant or other restriction
preventing the Executive from entering into employment with or carrying out
your responsibilities for National Waterworks, Inc., or which is in any way
inconsistent with the terms of this Agreement; and (ii) the Executive and the
Company agree to terminate that certain Employment Security Agreement dated on
or about April 18, 2002 by and between the Executive and U.S. Filter
Distribution, Inc. ("Distribution") which has been assigned to the Company's
subsidiary, National Waterworks, Inc. The Company's issuance of the

<PAGE>

Executive Stock is contingent upon the execution of this Agreement and the
Company's standard Employee Noncompeition, NonDisclosure, and Developments
Agreement attached hereto as Exhibit B.

                  (e)      As an inducement to the Company to issue the
Executive Stock to the Executive and as a condition thereto, the Executive
acknowledges and agrees that:

                           (i)     neither the issuance of the Executive Stock
         to the Executive nor any provision contained herein shall entitle the
         Executive to remain in the employment of the Company and its
         Subsidiaries, if any, or affect the right of the Company to terminate
         the Executive's employment at any time for any reason; and

                           (ii)    except as provided in any other agreement
         between the Company and/or National Waterworks, Inc. and the Executive,
         the Company shall have no duty or obligation to disclose to the
         Executive, and the Executive shall have no right to be advised of, any
         material information regarding the Company and its Subsidiaries, if
         any, at any time prior to, upon or in connection with the forfeiture of
         the Executive Stock upon the termination of the Executive's employment
         with National Waterworks, Inc.

                  (f)      In connection with the issuance and sale by the
Company to the Executive of the Executive Stock, the Company represents and
warrants that:

                           (i)     the Company is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and authority to own, lease
and operate the assets used in its business, to carry on its business as
presently conducted, to enter into this Agreement, to perform its obligations
hereunder, and to consummate the transactions contemplated hereby;

                           (ii)    the Company has taken all corporate action
necessary to authorize its execution and delivery of this Agreement, its
performance of its obligations thereunder, and its consummation of the
transactions contemplated thereby;

                           (iii)   this Agreement constitutes a valid and
binding obligation of the Company, enforceable in accordance with its terms; and

                           (iv)    the Executive Stock, when issued in
accordance with this Agreement, will be duly authorized and validly issued,
fully paid and nonassessable and will be free of all Encumbrances created by or
through the Company. For purposes of this clause, "Encumbrance" means any
security interest, mortgage, lien, pledge, charge, easement, reservation,
restriction, or similar right of any third party.

the Company's Board of Directors for acquisitions made by the Company (whether

by the Company's Board of Directors in the event that the Company acquires any
business(es) with an aggregate purchase price in excess of $10,000,000
(including any earnout components, etc.).

         "Net Working Capital Ratio" shall equal the simple average of the
Monthly Net Working Capital Ratios (as defined below) during such calendar year.
The "Monthly Net Working Capital Ratios" shall equal a fraction, the numerator
of which is the Net Working Capital (as defined below) calculated on the last
day of such calendar month, and the denominator of which is the product of
twelve (12) and the Net Sales (calculated in accordance with past practice)
generated by the Company during such calendar month. "Net Working Capital" shall

inventory over (ii) the Company's accounts payable, each as calculated in

<PAGE>

                  (b)      In the event the Executive ceases to be employed by
the Company or any of its Subsidiaries for any reason, then (i) all shares of
Executive Stock subject to clause (a)(i) above shall cease vesting effective as
of the Termination Date and, (ii) in the event that the Company achieves Minimum
EBITDA and/or achieves a Net Working Capital Ratio not to exceed the Maximum Net
Working Capital Ratio, as the case may be, with respect to the year in which
such termination occurs, the shares of Executive Stock subject to vesting with
respect to such year under clauses (a)(ii) or (a)(iii) multiplied by a fraction,
the numerator of which shall equal the number of whole months during such year
that the Executive remained employed with the Company and the denominator of
which is 12, shall be deemed vested as of the end of such year.

                  (c)      Notwithstanding the vesting terms set forth in
clause (a) above, upon a Termination Without Cause within twelve (12) months
after the consummation of a Sale, all Executive Stock subject to vesting
pursuant to clause (a)(i) above shall automatically and immediately vest.

                  (d)      Notwithstanding the vesting terms set forth in
clause (a) above, upon a Sale or Public Sale in which each of J.P Morgan

aggregate consideration or proceeds representing an amount which equals or
exceeds the sum of the amounts originally paid by J.P. Morgan Partners, LLC and
Thomas H. Lee Partners, L.P. and/or their affiliates with respect to the
purchase of the Company's equity securities on or about the Closing plus a rate
of return on such amounts equal to at least 25%, compounded annually, all
Executive Stock subject to vesting pursuant to clauses (a)(ii) and (a)(iii)
shall automatically and immediately vest.

month that the Executive remained employed with the Company or its Subsidiary

                  (f)      Notwithstanding the vesting terms set forth in
clause (a) above, if the Executive remains employed with the Company or any of

Effective Date, all Executive Stock subject to vesting pursuant to clauses
(a)(ii) and (a)(iii) shall automatically and immediately vest on the eighth
anniversary of the Effective Date.

                  3.       REPURCHASE OF SHARES.

                  (a)      In the event that the Executive ceases to be
employed by the Company or any of its Subsidiaries for any reason, then all
shares of Executive Stock (whether held by the Executive or by one or more of
the Executive's transferees) which as of the date of termination:

                           (i)     have not vested pursuant to Section 2 hereof,
         will be subject to repurchase by the Company, at its option (the
         "Non-Vested Repurchase

<PAGE>

         Option"), for the lower of the Original Purchase Price of the Executive
         Stock and Fair Market Value

                           (ii)    have vested pursuant to Section 2 hereof,
         will be subject to repurchase, solely in the event that the Executive
         ceases to be employed by the Company or any of its Subsidiaries as a
         result of a Termination for Cause, by the Company, at its option (the
         "Vested Repurchase Option"), for the lower of Original Purchase Price
         of the Executive Stock and Fair Market Value.

                  (b)      In the event of Sale, then all shares of Executive
Stock (whether held by the Executive or by one or more of the Executive's
transferees) which, as of the date of such Sale, have not vested pursuant to
Sections 2(a)(ii) and (a)(iii) hereof, will be subject to repurchase by the
Company, at its option (the "Non-Vested Sale Repurchase Option"; and together
with the Non-Vested Repurchase Option and the Vested Repurchase Option, the
"Repurchase Option"), for the lower of the Original Purchase Price of the
Executive Stock and Fair Market Value.

                  (c)      The Repurchase Option shall be exercised by the
Company, or its designee, by delivering to the Executive a written notice of
exercise and a check in the amount of the Original Purchase Price or Fair Market
Value, as determined in accordance with Sections 3(a) and (b) above. Upon
delivery of such notice and payment of the purchase price as described above,
the Company, or its designee, shall become the legal and beneficial owner of the
shares of Executive Stock being repurchased and all rights and interest therein
or related thereto, and the Company, or its designee, shall have the right to
transfer to its own name the number of shares of Executive Stock being
repurchased without further action by the Executive or any of his transferees.
If the Company or its designee elect to exercise the repurchase rights pursuant
to this Section 3 and the Executive or his transferee fails to deliver the
shares of Executive Stock in accordance with the terms hereof, the Company, or
its designee, may, at its option, in addition to all other remedies it may have,
deposit the purchase price in an escrow account administered by an independent
third party (to be held for the benefit of and payment over to the Executive or
his transferee in accordance herewith), whereupon the Company shall by written
notice to the Executive cancel on its books the certificates(s) representing
such shares of Executive Stock registered in the name of the Executive and all
of the Executive's or his transferee's right, title, and interest in and to such
shares of Executive Stock shall terminate in all respects.

                  (d)      Each holder of the Executive Stock shall promptly
return to the Company share certificates representing shares of the Executive
Stock repurchased pursuant to Sections 3(a) and (b) hereof. In the event such
certificates represent more shares of the Executive Stock than are required to
be forfeited, the Company shall, without charge, deliver to such holder of the
Executive Stock a new certificate representing such excess.

                  (e)      In the event that Executive Stock is repurchased
pursuant to this Section 3, the Executive and his successors, assigns or
Representatives shall take (at the Company's expense) all steps necessary and
desirable to obtain all required third-party,

<PAGE>

governmental and regulatory consents and approvals and take all other actions
necessary and desirable to facilitate consummation of such repurchase in a
timely manner.

                  4.       LEGEND.

that the shares of Executive Stock are subject to and restricted by the
Stockholders' Agreement and with respect to such shares of Executive Stock, the
Executive shall be an "Other Stockholder" as such term is used in the

                  (c)      The Executive agrees that so long as the Executive
owns shares of Executive Stock which have not vested pursuant to Section 2
hereof, the Executive shall be obligated to vote all of his, her or its shares
of Executive Stock which have not vested pursuant to Section 2 hereof in the
same manner and proportions as the votes cast by the holders of the Company's
voting capital stock not subject to such repurchase rights. If the Executive
fails or refuses to vote his, her or its shares of Executive Stock which have
not vested pursuant to Section 2 hereof as required by, or votes his, her or its
shares of Executive Stock which have not vested pursuant to Section 2 hereof in
contravention of this Section 5(c), then the Executive hereby grants to each of
the President and Treasurer of the Company, acting solely in his or her capacity

parties hereto that the provisions of this Agreement be enforced to the fullest
extent permissible under the laws and public policies applied in each
jurisdiction in which enforcement is sought. Accordingly, if any particular
provision of this Agreement shall be adjudicated by a court of competent
jurisdiction to be invalid, prohibited or unenforceable for any reason, such
provision, as to such jurisdiction, shall be ineffective, without invalidating
the remaining provisions of this Agreement or affecting the validity or
enforceability of this Agreement or affecting the validity or enforceability of
such provision in any other jurisdiction. Notwithstanding the foregoing, if such
provision could be more narrowly drawn so as not to be invalid, prohibited or
unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so
narrowly drawn, without invalidating the remaining provisions of this

Executive Stock); provided that the rights and obligations of the Executive
under this Agreement shall not be assignable except in connection with a
permitted transfer of Executive Stock hereunder.

                  (e)      Governing Law. THIS AGREEMENT WILL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING

OF DELAWARE, OR ANY OTHER JURISDICTION), THAT WOULD CAUSE THE LAWS OF ANY
JURISDICTION OTHER THAN THE STATE OF DELAWARE TO BE APPLIED. IN FURTHERANCE OF
THE FOREGOING, THE INTERNAL LAW OF THE STATE OF NEW YORK WILL CONTROL THE
INTERPRETATION AND CONSTRUCTION OF THIS AGREEMENT, EVEN IF UNDER SUCH
JURISDICTION'S CHOICE OF LAW OR CONFLICT OF LAW ANALYSIS, THE SUBSTANTIVE LAW OF
SOME OTHER JURISDICTION WOULD ORDINARILY APPLY.

                  (f)      Jurisdiction and Venue. SUBJECT TO THE TERMS OF THIS

HERSELF AND IN RESPECT OF ITS, HIS OR HER PROPERTY WITH RESPECT TO SUCH ACTION.

PROCESS REQUIRED BY ANY SUCH COURT SHALL CONSTITUTE VALID AND LAWFUL SERVICE OF
PROCESS AGAINST THEM,

any such Person granted rights hereunder whether or not such Person is a
signatory hereto shall be entitled to enforce its rights under this Agreement
specifically to recover damages and costs (including reasonable attorney's fees)
for any breach of any provision of this Agreement and to exercise all other
rights existing in its favor. The parties hereto agree and acknowledge that
money damages may not be an adequate remedy for any breach of the provisions of
this Agreement and that any party and any such Person granted rights hereunder
whether or not such Person is a signatory hereto may in its sole discretion
apply to any court of law or equity of competent jurisdiction for specific
performance and/or other injunctive relief (without posting any bond or deposit)
in order to enforce or prevent any violations of the provisions of this
Agreement.

                  (h)      Amendment and Waiver. The provisions of this
Agreement may be amended and waived only with the prior written consent of the
Company and the Executive and no course of conduct or failure or delay in
