offer and sale of the Units have not been registered under the 1933
Act;

			
		(b) 	the Units must be held and
the Management Member must continue to bear the economic risk of the

the Units may never be so
registered;

			
		(c) 	there is no
established market for the Units and it is not anticipated that there

Section 1.02.    Additional Investment
Representations.    Each Management Member represents and
warrants that:

			
		(a) 	the Management
Member’s financial situation is such that such Management Member

Management Member’s current needs and personal contingencies,
and can afford to suffer a complete loss of the Management
Member’s investment in the Units;

Management Member’s knowledge and experience in financial and
business matters are such that the Management Member is capable of
evaluating the merits and risks of the investment in the
Units;

			
		(c) 	the Management Member understands that
the Units are a speculative investment which involves a high degree of
risk of loss of Management Member’s investment therein, there
are substantial restrictions on the transferability of the Units and,
on the date on which such Management Member acquires such Units and for
an indefinite period following such date, there will be no public
market for the Units and, accordingly, it may not be possible for the
Management Member to liquidate the Management Member’s
investment including in case of emergency, if at
all;

			
		(d) 	the terms of this Agreement provide that

prospects or other matters;

		(f) 	the Management Member
has been given the opportunity to examine all documents and to ask
questions of, and to receive answers from, the Company and its
representatives concerning the Company and its subsidiaries, the
acquisition of Nalco Company and certain Subsidiaries of Nalco
International S.A.S. by subsidiaries of the Company, the LLC Agreement,
the Company’s organizational documents and the terms and
conditions of the purchase of the Units and to obtain any additional
information which the Management Member deems necessary;

Section
2.01.    Transfer.    (a) Until the occurrence of a
Qualified IPO, except as required by law, no Management Member may

hypothecate, pledge, encumber, grant a security interest in, offer,
sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, lend,

Act; provided, that no Management Member shall make a Transfer
pursuant to this clause (iv) without the Company's prior, written
approval.

(c)    No Transfer by any Management Member may be
made pursuant to this Article II unless (i) the transferee has
agreed in writing to be bound by the terms and conditions of this
Agreement and the LLC Agreement (other than if the Transfer is
conducted in accordance with the Registration Rights Agreement or the
requirements of Rule 144 promulgated under the 1933 Act),
(ii) the Transfer complies in all respects with the applicable
provisions of this Agreement, (iii) the Transfer complies in all
respects with applicable federal and state securities laws, including
the 1933 Act and (iv) the Transfer is made in compliance with all

hereof.

(d) No Transfer by any Management Member may be
made pursuant to this Article II (except pursuant to an effective
registration statement under the 1933 Act) unless and until such
Management Member has first delivered to the Company an opinion of
counsel (reasonably acceptable in form and substance to the Company)
that neither registration nor qualification under the 1933 Act and
applicable state securities laws is required in connection with such
Transfer.

Section 2.02.    Call Option.    (a) If a
Management Member’s Services to the Company or any Subsidiary
terminate for any of the reasons set forth in clauses (i), (ii) or
(iii) below (each such event a ‘‘Termination
Event’’), the Company shall have the right but
not the obligation to purchase, from time to time after such
termination of Services, any Units held by such Management Member for a
period of 60 days (subject to extension as provided below) immediately
following the later of (A) the date of the Termination Event and (B)
the date that is six (6) months and one day after the date on which
such Management Member acquired such Unit (the later of (A) and (B),
the ‘‘First Purchase 

4

Date’’), and such
Management Member shall be required to sell to the Company, any or all
of such Units then held by such Management Member, at a price per Unit
equal to the applicable purchase price determined pursuant to Section
2.02(c):

(i) if such Management
Member’s Service with the Company and its Subsidiaries is
terminated due to the Disability or death of the Management
Member;

(ii) if such Management
Member’s Service with the Company and its Subsidiaries is
terminated by the Company and its Subsidiaries without Cause or by the
Management Member for any
reason;

(iii) if such Management
Member’s Service with the Company and its Subsidiaries is
terminated by the Company or any of its Subsidiaries for
Cause.

(b) If on the 61st day following the date of the
Termination Event, the Company has not purchased all of a terminated
Management Member’s Units, and the Company has not opted to
extend its 60 day election period pursuant to Section 2.02(d), the
Company shall on or before the 61st day provide written
notice to the Investor Groups of (i) its decision not to purchase some
or all of such Units and (ii) the number of such Management
Member’s Eligible Units (defined below) which the Company did
not purchase, and the Investor Groups shall have the right to purchase
and such Management Member shall be required to sell to the Investor
Group(s), any or all of the Units (the ‘‘Eligible
Units’’) then held by such Management Member at a
price per Unit equal to the applicable purchase price determined
pursuant to Section 2.02(c). The Investor Groups’ rights to
purchase such Eligible Units and each Management Member’s
corresponding obligation to sell such Eligible Units shall terminate on
the 120th day following the date of the Termination Event. Upon receipt
of the written notice described above, each Investor Group desiring to
purchase Units shall within 45 days of receipt of the Company’s
notice provide written notice to the Company, specifying that such
Investor Group is willing to purchase either (i) its pro rata
share of the Eligible Units (based upon the number of Units held by
such Investor Group relative to the total number of Units held by all
of the Investor Groups), (ii) a number of Eligible Units less than such
Investor Group’s pro rata share, or (iii) any and all
Units available to be purchased; provided, that the Investor
Groups shall, as much as reasonably practicable, consult with each
other and coordinate the exercise of rights such that all Eligible
Units are elected to be purchased. Upon receipt of the Investor
Groups’ respective notices, the Company will notify the
Management Member of the Investor Group(s)’ elections and the
Management Member will be obligated to sell (x) to the Investor Groups
making elections described in clauses (i) and (ii) of the preceding
sentence, the number of Eligible Units elected to be purchased by such
Investor Groups and (y) all remaining Eligible Units, if any, to the
Investor Groups making the election described in clause (iii) of the
preceding sentence to such Investor Group(s) on a pro rata basis
(based upon the number of Units held by such Investor Group relative to
the total number of Units held by all of the Investor Groups making
such election), but in no event more that any such Investor Groups
elected to purchase.

(c) In the event of a purchase by
the Company pursuant to Section 2.02(a) and/or the Investor Group(s)
pursuant to Section 2.02(b) (each a ‘‘Units
Buyer’’), the purchase price shall
be:

(i) in the case of a Termination
Event specified in Section 2.02(a)(i) or 2.02(a)(ii) a price per Unit
equal to the most recently determined Fair Market Value, and

(ii) in the case of a Termination Event
specified in Section 2.02(a)(iii), a price per Unit equal to the lesser
of (1) Fair Market Value and (2) Cost.

(d) The Units Buyer
may pay the purchase price for such Units (i) by delivery of
funds deposited into an account designated by the Management Member, a
bank cashier’s check, a certified check or a company check of
the Units Buyer for the purchase price; (ii) if the Units Buyer
is the Company and is prohibited from paying cash by financing or
liquidity constraints and is unable to pay the purchase price as
provided in clause (iii), by delaying the exercise of the purchase
right described under Section 2.02(a) until the earlier of (x) when the
financing restrictions lapse and (y) when the Company is able to pay
the purchase price as provided in clause (iii); or (iii) if the Units
Buyer is the Company and has the right to purchase such Units during
the period following a Qualified IPO 

5

(including in respect of a purchase that was
delayed pursuant to clause (ii)), by delivery of a number of shares of
Issuer Common Stock determined by dividing (A) the aggregate purchase
price of the Units being sold by such Management Member by (B) the
Public Share FMV as of the close of trading on the trading day
immediately prior to the delivery thereof to the Management Member.
Notwithstanding anything to the contrary in this Agreement, the Units
Buyer may deduct and withhold from the amounts otherwise payable
pursuant to this Agreement such amounts as necessary to
comply with the Internal Revenue Code of 1986, as amended
(the "Code"), or
any other provision of applicable law, with respect to
the making of such payment.

(e)    Notwithstanding anything to
the contrary elsewhere herein, the Company shall not be obligated to
purchase any Units at any time pursuant to this Section 2.02,
regardless of whether it has delivered a notice of its election to
purchase any such Units, (i) to the extent that (A) the purchase
of such Units (together with any other purchases of Units pursuant to
Sections 2.02 or 2.03 hereof, or pursuant to similar provisions in any
other agreements with other investors of which the Company has at such
time been given or has given notice) or (B) in the event of an election
to purchase such Units with shares of Issuer Common Stock, the issuance
of such shares by the IPO Entity, the purchase of such shares by the
Company or the distribution of such shares to the Management Member
would result (x) in a violation of any law, statute, rule,
regulation, policy, order, writ, injunction, decree or judgment
promulgated or entered by any governmental authority applicable to the
Company or any of its Subsidiaries or any of its or their assets
(including any unavailability of a registration statement or exemption
from registration necessary to allow delivery of shares of Issuer
Common Stock to the Management Member), (y) after giving effect
thereto (including any dividends or other distributions or loans from a
Subsidiary of the Company to the Company in connection therewith), in a
Financing Default or (z) in the Company being required to disgorge any
profit to the IPO Entity pursuant to Section 16(b) of the 1934 Act,
(ii) if immediately prior to such purchase of Units, issuance of
Issuer Common Stock or purchase of shares of Issuer Common Stock, as
the case may be, there exists a Financing Default which prohibits such
issuance or purchase (including any dividends or other distributions or
loans from a Subsidiary of the Company to the Company in connection
therewith), or (iii) if the Company does not have funds
available to effect such purchase of Units or Issuer Common Stock. The
Company shall within 30 days of learning of any such fact so notify the
Management Member that it is not obligated to purchase such Units and
has deferred its right to make such purchase until such violation,
potential liability under the 1933 Act or 1934 Act, Financing Default
or unavailability of funds would not result therefrom or has ceased.
The Company agrees to use commercially reasonable efforts to cure any
such Financing Default that is curable. To the extent that, pursuant to
this Section 2.02(e), the Company is not obligated to pay for a
Management Member's Units in accordance with one of the payment
methods described in the first sentence of Section 2.02(d), the Company
shall, except as otherwise permitted by this Section 2.02(e), be
required to pay for such Units pursuant to an alternate method of
payment described in the first sentence of Section 2.02(d).

(f)    Notwithstanding anything to the contrary contained in this
Section 2.02, any Units which the Company has elected to purchase from
a Management Member, but which in accordance with Section 2.02(e) are
not purchased at the applicable time provided in this Section 2.02,
shall be purchased by the Company on the tenth Business Day after such
date or dates that it is no longer permitted to defer purchasing such
Units under Section 2.02(e), and the Company shall give such Management
Member five Business Days prior notice of any such
purchase.

Section 2.03.    Put Right.    (a) Subject
to the Call Right described in Section 2.02, following a Qualified IPO
and for so long as no Termination Event pursuant to Section
2.02(a)(iii) shall have occurred with respect to a Management Member,
such Management Member shall have the right, but not the obligation, to
sell (the ‘‘Put Right’’)
beginning on the later of (x) the first date immediately following the
expiration of any Company or underwriter
‘‘lock-up’’ period applicable to such
Qualified IPO and (y) the date that is at least six (6) months and one
day after, the Sale Date ( the later of (x) and (y) shall be referred
to as the ‘‘First Put Date’’), and
the Company shall be required to purchase from such Management Member,
a number of such Management Member's Units as determined by such
Management Member, at a price per Unit equal to the Fair Market Value
as of the date the 

6

Management Member exercises such Put Right.
For the avoidance of doubt, subject to the Call Right described in
Section 2.02, a Management Member shall remain entitled to the Put
Right following a Termination Event pursuant to Sections 2.02(a)(i) or
(ii) with respect to such Management Member.

(b)    Each
Management Member who desires to sell any of his or her Units following
the applicable First Put Date shall send written notice to the Company
of his or her intention to sell such Units pursuant to this Section
2.03. Subject to the exercise of any Call Right pursuant to Section
2.02, the closing of the purchase shall take place at the principal
office of the Company on a date specified by the Company no later than
30 days after the giving of such notice.

(c)    At the closing
of a purchase pursuant to a Put Right, the Company will pay to the
Management Member the purchase price for such Units (determined in
accordance with Section 2.03(a)) by delivery of a number of shares of
Issuer Common Stock determined by dividing (A) the aggregate purchase
price of the Units being sold by such Management Member by (B) the
Public Share FMV as of the close of trading on the trading day
immediately prior to the delivery thereof to the Management Member.

(d)    Notwithstanding anything to the contrary elsewhere herein,
the Company shall not be obligated to purchase any Units at any time
pursuant to this Section 2.03 (i) to the extent that (A) the
purchase of such Units (together with any other purchases of Units
pursuant to Sections 2.02 or 2.03 hereof, or pursuant to similar
provisions in any other agreements with other investors of which the
Company has at such time been given or has given notice) or (B) the
issuance of shares by the IPO Entity or the purchase of such shares by
the Company would result (x) in a violation of any law, statute,
rule, regulation, policy, order, writ, injunction, decree or judgment
promulgated or entered by any governmental authority applicable to the
Company or any of its Subsidiaries or any of its or their assets
(including any unavailability of a registration statement or exemption
from registration necessary to allow delivery of shares of Issuer
Common Stock to the Management Member(s)), (y) after giving
effect thereto, in a Financing Default or (z) in the Company being
required to disgorge any profit to the IPO Entity pursuant to Section
16(b) of the 1934 Act or (ii) if immediately prior to such
purchase of Units, issuance of Issuer Common Stock or purchase of
shares of Issuer Common Stock, as the case may be, there exists a
Financing Default which prohibits any such issuance or purchase. The
Company agrees to use commercially reasonable efforts to cure any such
Financing Default that is curable. To the extent that the Company is
not obligated to pay for any Units as described in the first sentence
of Section 2.03(c) pursuant to the terms of this Section 2.03(d), the
Company shall promptly notify any Management Member that has delivered
a notice of exercise of a Put Right that it is not obligated to
purchase such Units and has deferred its right to make such purchase
until such violation, potential liability under the 1933 Act or 1934
Act or Financing Default would not result therefrom or has ceased.

(e)    Notwithstanding anything to the contrary contained in this
Section 2.03, any Units which a Management Member has elected to sell
to the Company, but which in accordance with Section 2.03(d) are not
purchased at the applicable time provided in this Section 2.03, shall
be purchased by the Company on the tenth Business Day after such date
or dates that it is no longer permitted to defer purchasing such Units
under Section 2.03(d), and the Company shall give such Management
Member five Business Days prior notice of any such
purchase.

Section 2.04.    Tag-Along Right. If,
at any time prior to a Qualified IPO, one or more Sponsor Members
propose to Transfer, in a single transaction or a series of related
transactions, a number of Units representing at least 30% of the
Sponsor Members’ aggregate Initial Equity Stakes (as defined in
the LLC Agreement) to any Person (other than a Transfer to a Permitted
Transferee (as defined in the LLC Agreement) of any such Sponsor Member
and other than a Transfer in accordance with the Registration Rights
Agreement and other than to another Sponsor Member) (a
‘‘Tag-Along Purchaser’’),
then, unless such transferring Sponsor Member(s) are entitled to give
and do give a Drag-Along Sale Notice (as defined in the LLC Agreement)
and no other Sponsor Member(s) has elected to purchase its pro
rata share of such Units pursuant to Section 2.04(a) of the Sponsor
Agreement, the Company shall first provide written notice to each of
the Management Members, which notice (the
‘‘Tag-Along Notice’’) shall
state: (i) the maximum number of Units proposed to be

7

Transferred (the
‘‘Tag-Along Securities’’);
(ii) the purchase price per Unit (the ‘‘Tag-Along
Price’’) for the Tag-Along Securities and
(iii) any other material terms and conditions of such sale,
including the proposed transfer date (which date will be within 60
business days after the termination of the Election Period (defined
below), subject to extension for any required regulatory approvals).
Each of the Management Members that has been provided with the
Tag-Along Notice (each, a ‘‘Tag-Along
Manager’’) shall have the right to sell to such
Tag-Along Purchaser, upon the terms set forth in the Tag-Along Notice,
up to the aggregate number of Units which are held by such Tag-Along
Manager multiplied by a fraction, the numerator of which is the
aggregate number of Units proposed to be sold by the transferring
Sponsor Member as reflected in the Tag-Along Notice and the denominator
of which is the total number of Units which are held by the
transferring Sponsor Member. If the number of Units elected to be sold
by the Tag-Along Managers and any other individuals identified from
time to time on Exhibit A to the LLC Agreement, the transferring
Sponsor Member and any other Sponsor Members electing to participate in
such sale is greater than the number of Tag-Along Securities specified
in the Tag-Along Notice, the number of Units being sold by each such
seller shall be reduced such that the applicable seller shall be
entitled to (and obligated to) sell only their pro rata share of
Units (based on the aggregate number of Units held by such seller to
the total number of Units held by all of such electing sellers). The
transferring Sponsor Member(s), the Sponsor Members electing to
participate in such sale and the Tag-Along Manager(s) exercising their
rights pursuant to this Section 2.04 shall effect the sale of the
Tag-Along Securities, and such Tag-Along Manager(s) shall sell the
number of Tag-Along Securities required to be sold by such Tag-Along
Manager(s) pursuant to this Section 2.04(a) within 60 business days
after the expiration of the Election Period, subject to extension for
any required regulatory approvals.

(b)    The tag-along rights
provided by this Section 2.04 must be exercised by any Tag-Along
Manager wishing to sell its Units within 10 business days
following the date of delivery of the Tag-Along Notice (the
‘‘Election Period’’), by
delivery of a written notice to the Company indicating such Tag-Along
Manager’s wish to irrevocably exercise its rights and specifying
the number of Units (up to the maximum number of Units owned by such
Tag-Along Manager requested to be purchased by such Tag-Along
Purchaser) it wishes to sell; provided that any Tag-Along
Manager may waive its rights under this Section 2.04 prior to the
expiration of such 10-business day period by giving written notice to
the Company, which will be distributed by the Company to the
transferring Sponsor Member(s). The failure of a Tag-Along Manager to
respond within such 10-business day period shall be deemed to be a
waiver of such Tag-Along Manager’s rights under this Section
2.04.

(c) In connection with any sale pursuant to this
Section 2.04, each Tag-Along Manager shall make to the Tag-Along
Purchaser the same representations, warranties, covenants, indemnities
and agreements as the transferring Sponsor Member(s) makes in
connection with the proposed transfer (except that in the case of
representations, warranties, covenants, indemnities and agreements
pertaining specifically to the transferring Sponsor Member(s), a
Tag-Along Manager shall make the comparable representations,
warranties, covenants, indemnities and agreements); provided
that all representations, warranties and indemnities shall be made by
the transferring Sponsor Member(s) and such Tag-Along Manager severally
and not jointly and that the liability of the transferring Sponsor
Member(s) and such Tag-Along Manager thereunder shall be borne by each
of them on a pro rata basis. The Tag-Along Managers shall
receive the same type and amount of consideration (and rights) per Unit
as is paid or delivered to the transferring Sponsor Member(s) in the
sale pursuant to Section 2.04(a).

(d) No Transfer of any
Unit pursuant to this Section 2.04 shall be effective unless and until
the applicable transferee agrees to be bound by all of the terms and
conditions of the LLC Agreement.

Section 2.05. Fair
Market Value.    Either the Board or the compensation committee
of the Board shall undertake in good faith to determine the Fair Market
Value of the Units no less frequently than annually and on a quarterly
basis if necessary in connection with a Transfer of Units to the
Company pursuant to Section 2.02 or Section 2.03 of this Agreement.
Such determination shall be made in the sole discretion of the Board or
the compensation committee of the Board, as the case may
be.

(iii) required by law to be disclosed; provided that in
connection with sub-clause (iii), the Management Member shall give
prompt written notice to the Company of such requirement, disclose no
more information than is so required, and cooperate with any attempts

consent of the Board. This Agreement shall be binding upon and inure to
the benefit of the successors and assigns of the parties pursuant to
this paragraph.

Section 5.02.    Conversion; Restructuring;
Recapitalization; Reorganization.    (a) In connection with a
Qualified IPO, pursuant to Section 4.06 of the LLC Agreement, the Units

that the restrictions contained in this Agreement would in such case be

become parties.

(b) The Company may, at the
discretion of the Board and in accordance with applicable U.S. state

Members immediately prior to such Restructuring Event. It is

agree:

1.    Consulting Relationship.    Subject to
the terms and conditions set forth herein, the Company shall retain
Consultant to perform the following services for a period of up to two
years: supervise the completion of pending SAP rollout and other

any benefits, medical insurance, worker’ compensation or
compensation benefits that are available to employees of the Company
either by plan, agreement or policy, and the Company shall not withhold
any taxes or other amounts from the amounts paid hereunder or otherwise
treat Consultant as if he were an employee. Consultant’s rights
to payments and other amounts from the Company shall be limited to
those contractual rights provided in this Agreement.

2.    Performance.    During the Term, Consultant will
serve the Company faithfully and to the best of his ability and will
devote his full business time, energy, experience and talents to the
business of the Company, provided that Consultant has pending part-time
commitments (which will not interrupt his performance of the Services)
which he is permitted to complete on or before October
31,  2004. At his option, Consultant, upon thirty (30) days
advance written notice to the Company may reduce his service level
hereunder by up to 50% (the ‘‘Reduced

3.    Term.    Subject
to: the extension for purposes of the Management Equity Plan described
in Section 4 below, the term of this Agreement shall begin upon the

Agreement by providing notice to Consultant (‘‘At Will

termination.

Agreements’’). Consultant may purchase $200,000 in A
Units subject to the Management Equity Plan, by executing the
Management Equity Plan Agreements, making the payment to Nalco LLC for
$200,000 and executing this Agreement (the ‘‘Consultant A
Units’’). (b) Consultant acknowledges that the Management
Equity Plan was initially created for employees of the Company and that
the Management Equity Plan Agreements refer to the participants as
employees of the Company, but that notwithstanding any such references
Consultant shall not be an employee of the Company or Nalco LLC and
shall not have any rights as an employee by reason of his participation
in the Management Equity Plan or his execution of the Management Equity
Plan Agreements. (c) In the event that Consultant elects Reduced
Services pursuant to Section 2 during the Term, the Company shall have
the option to purchase from Consultant a pro-rata percentage of the
Consultant A Units at their then fair market value (as determined
pursuant to the Management Equity Plan) where such pro-rata percentage
equals the percentage reduction in Services elected by Consultant.
Further, in the event Consultant elects to terminate this Agreement at
his will during the Term, the Company shall have the option to purchase
all of the Consultant A Units at their then fair market value. (d)
These call options are in addition to the call options in the

Company in the event of certain conditions, including an imposition of
a certain tax on A Units and continued service to the Company on

Bonus’’). In the event that the certain tax described in
the Contingent Bonus is imposed upon Consultant, the Company shall
continue to pay Consultant $1 per month for the period July

Agreement shall be extended during that Interim Period to permit
Consultant the opportunity to receive the Contingent Bonus on or about

contained herein shall not in any way be affected or impaired, and the

disbursements (including the costs of the American Arbitration
Association and the arbitrator) related to such matter or issue
provided that the party is successful overall on a material portion of
the arbitration, provided, however, the Company shall only be
entitled to an award of legal fees and disbursements if the resolution
of any such contest or dispute includes a finding that
Consultant's claims in such contest or dispute were frivolous or
brought in bad faith.

Agreement: Modification.    This Agreement constitutes the
entire agreement of the parties hereto with respect to the subject
matter hereof, supersedes all prior agreements and undertakings, both
