Management Members' Representations, Warranties and Agreements

         (a) Units Unregistered. Each Management Member acknowledges and
represents that such Management Member has been advised by the Company that:

                  (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 offer and sale of such Units are subsequently registered
         under the 1933 Act and all applicable state securities laws or an
         exemption from such registration is available and the Units may never
         be so registered;

                  (C) there is no established market for the Units and it is not
         anticipated that there will be any public market for the Units in the
         foreseeable future;








                  (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
                  REGISTRATION THEREUNDER. THE SECURITIES REPRESENTED BY THIS
                  CERTIFICATE ARE ALSO SUBJECT TO CERTAIN TRANSFER AND OTHER
                  RESTRICTIONS SET FORTH IN THE LIMITED LIABILITY COMPANY

                  CERTAIN OF ITS MEMBERS, THE MANAGEMENT MEMBERS AGREEMENTS,
                  DATED AS OF JUNE 11, 2004 AMONG NALCO LLC AND CERTAIN
                  MANAGEMENT MEMBERS NAMED THEREIN, THE REGISTRATION RIGHTS
                  AGREEMENT AMONG NALCO LLC AND CERTAIN OF ITS MEMBERS AND,
                  AMONG OTHER THINGS, MAY NOT BE OFFERED OR SOLD EXCEPT IN
                  COMPLIANCE WITH SUCH TRANSFER RESTRICTIONS. COPIES OF SUCH
                  LIMITED LIABILITY COMPANY AGREEMENT, SUCH MANAGEMENT MEMBERS
                  AGREEMENTS AND SUCH REGISTRATION RIGHTS AGREEMENT ARE ON FILE
                  WITH THE SECRETARY OF THE LIMITED LIABILITY COMPANY AND ARE
                  AVAILABLE WITHOUT CHARGE UPON WRITTEN REQUEST THEREFOR. THE
                  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.







         (b) 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.


Transfers; Acceleration

         (c) Transfer. (i) 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").

                  (A) 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.

                  (B) 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.







         (d) 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):

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

                  (2) 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;

                  (3) 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.

         (e) 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.

         (f) Tag-Along Right. (ii) 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.

                  (A) 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.

         include the disclosure or other use in any manner of Confidential
         Information.

                  (B) Except as required by law or except in connection with any
         proposed transfer in accordance with this Agreement or any transfer to
         a Management Permitted Transferee, the Management Member will not
         disclose to anyone, other

         Company, will execute an assignment or an agreement to assign solely in

shall be binding upon and inure to the benefit of the successors and assigns of

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

that the restrictions contained in this Agreement would in such case be
replicated in one or more management shareholders agreements governing the
Reclassified Securities to which the Management Members would become parties.

         (b) The Company may, at the discretion of the Board and in accordance
with applicable U.S. state and federal law (including the 1933 Act and the 1934
