      (a)   the 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 investment in the Units unless the

            1933 Act and all applicable state securities laws or an exemption
            from such registration is available and the Units may never be so

      (d)   a restrictive legend in the form set forth below shall be placed on
            the certificates representing the Units:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE
                  ORIGINALLY ISSUED ON ______________, HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND
                  MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE
                  REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION FROM

                  AGREEMENT AMONG NALCO LLC AND CERTAIN OF ITS MEMBERS AND,
                  AMONG OTHER THINGS, MAY NOT BE OFFERED OR SOLD EXCEPT IN

                  HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE,
                  AGREES TO BE BOUND BY ALL OF THE APPLICABLE PROVISIONS OF THE
                  AFORESAID AGREEMENTS.";

      (e)   a restrictive legend in the form set forth below shall be placed on
            the certificates representing the Units held by Georgia residents:

                  "THESE SECURITIES HAVE BEEN ISSUED OR SOLD IN RELIANCE ON
                  PARAGRAPH 13 OF CODE SECTION 10-5-9 OF THE "GEORGIA SECURITIES
                  ACT OF 1973," AND MAY NOT BE SOLD OR TRANSFERRED EXCEPT IN A
                  TRANSACTION WHICH IS EXEMPT UNDER SUCH ACT OR PURSUANT TO AN
                  EFFECTIVE REGISTRATION UNDER SUCH ACT."; and




      (f)   a notation shall be made in the appropriate records of the Company
            indicating that the Units are subject to restrictions on transfer
            and, if the Company should at some time in the future engage the
            services of a securities transfer agent, appropriate stop-transfer
            instructions may be issued to such transfer agent with respect to
            the Units.

            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 can afford to bear the economic risk of holding
            the Units for an indefinite period of time, has adequate means for
            providing for the 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;

      (b)   the 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 if the Management Member
            ceases to provide services to the Company and its Affiliates, the
            Company and its Affiliates have the right to repurchase the Units at
            a price which may be less than the Fair Market Value thereof;

      (e)   the Management Member understands and has taken cognizance of all
            the risk factors related to the purchase of the Units and, other
            than as set forth in this Agreement, no representations or
            warranties have been made to the Management Member or Management
            Member's representatives concerning the Units, the Company, the
            Subsidiaries or their respective 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; and

      (g)   all information which the Management Member has provided to the
            Company and the Company's representatives concerning the Management
            Member and the Management Member's financial position is complete
            and correct as of the date of this Agreement.

            Section 1.04.    Contingent Bonus. The Company shall cause one of
its Subsidiaries to pay a bonus to Management Members in the circumstances set
forth in Exhibit A.

                                   ARTICLE II

                             Transfers; Acceleration

            Section 2.01.    Transfer. (a) Until the occurrence of a Qualified
IPO, except as required by law, no Management Member may directly or indirectly,
sell, contract to sell, give, assign, 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, or otherwise transfer or dispose of any economic, voting or other rights
in or to (collectively, "Transfer") any Units except pursuant to (i) Article XI
of the LLC Agreement, (ii) Sections 2.02 or 2.04 hereof or (iii) a Transfer to a
Manager Permitted Transferee (each a "Permitted Transfer").

            (b)   Following a Qualified IPO and the expiration of any
underwriter or Company "lock-up" period (as provided for in Section 4(a) of the
Registration Rights Agreement or otherwise) applicable to such Qualified IPO,
each Management Member may only Transfer its Units pursuant to (i) a Permitted
Transfer, (ii) a Transfer pursuant to Section 2.03, (iii) a Transfer in
accordance with the Registration Rights Agreement or (iv) a Transfer conducted
in accordance with the requirements of Rule 144 promulgated under the 1933 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 applicable Company policies and restrictions (including
any trading "window periods" or other policies regulating insider trading);
provided, that the conditions to Transfer described in clause (i) above shall
not apply to a Transfer pursuant Article XI of the LLC Agreement or Sections
2.02, 2.03 or 2.04 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 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 (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 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. (a) 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 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.

contemplated that the restrictions contained in this Agreement would in such
