         "Fixed Charge Coverage Ratio" means, with respect to any Person for any

Receivables Financing, in which case interest expense shall be computed based
upon the average daily balance of such Indebtedness during the applicable
period) or issues or redeems Preferred Stock subsequent to the commencement of
the period for which the Fixed Charge Coverage Ratio is being calculated but

is made (the "Calculation Date"), then the Fixed Charge Coverage Ratio shall be
calculated giving pro forma effect to such Incurrence or redemption of
Indebtedness, or such issuance or redemption of Preferred Stock, as if the same
had occurred at the beginning of the applicable four-quarter period.

         For purposes of making the computation referred to above, Investments,
acquisitions, dispositions, mergers, consolidations and discontinued operations
(as determined in accordance with GAAP), in each case with respect to an
operating unit of a business, that Holdings or any of its Restricted
Subsidiaries has both determined to make and made after the Issue Date and
during the four-quarter reference period or subsequent to such reference period
and on or prior to or simultaneously with the Calculation Date shall be
calculated on a pro forma basis assuming that all such Investments,
acquisitions, dispositions, mergers, consolidations and discontinued operations
(and the change of any associated fixed charge obligations and the change in
EBITDA resulting therefrom) had occurred on the first day of the four-quarter
reference period. If since the beginning of such period any Person that
subsequently became a Restricted Subsidiary or was merged with or into Holdings
or any Restricted Subsidiary since the beginning of such period shall have made
any Investment, acquisition, disposition, merger, consolidation or discontinued
operation, in each case with respect to an operating unit of a business, that
would have required adjustment pursuant to this definition, then the Fixed
Charge Coverage Ratio shall be calculated giving pro forma effect thereto for
such period as if such Investment, acquisition, disposition, discontinued
operation, merger or consolidation had occurred at the beginning of the
applicable four-quarter period.

         For purposes of this definition, whenever pro forma effect is to be
given to any transaction, the pro forma calculations shall be made in good faith
by a responsible financial or accounting officer of the Company. If any
Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest on such Indebtedness shall be calculated as if the rate in
effect on the Calculation Date had been the applicable rate for the entire
period (taking into account any Hedging Obligations applicable to such
Indebtedness if such Hedging Obligation has a remaining term in excess of 12
months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at
an interest rate reasonably determined by a responsible financial or accounting
officer of the Company to be the rate of interest implicit in such Capitalized
Lease Obligation in accordance with GAAP. For purposes of making the computation
referred to above, interest on any Indebtedness under a revolving credit
facility computed on a pro forma basis shall be computed based upon the average
daily balance of such Indebtedness during the applicable period. Interest on
Indebtedness that may optionally be determined at an interest rate based upon a
factor of a prime or similar rate, a eurocurrency

                                      -14-

interbank offered rate, or other rate, shall be deemed to have been based upon
the rate actually chosen, or, if none, then based upon such optional rate chosen
as the Company may designate. Any such pro forma calculation may include
adjustments appropriate, in the reasonable determination of the Company as set
forth in an Officers' Certificate, to reflect (1) operating expense reductions
and other operating improvements or synergies reasonably expected to result from
any acquisition or merger (including, to the extent applicable, from the
Transactions) and (2) all adjustments used in connection with the calculation of
"Pro Forma Adjusted EBITDA" as set forth in footnote (h) to the "Notes to

Financial Information" in the Offering Memorandum to the extent such
adjustments, without duplication, continue to be applicable to such four-quarter
period.

basis in accordance with GAAP) to (2) EBITDA of such Person for the four full
fiscal quarters for which internal financial statements are available
immediately preceding such date on which such additional Indebtedness is
Incurred. In the event that Holdings or any of its Restricted Subsidiaries
Incurs or redeems any Indebtedness subsequent to the commencement of the period

shall be calculated on a pro forma basis assuming that all such Investments,
acquisitions, dispositions, mergers, consolidations and discontinued operations

the four-quarter reference period. If since the beginning of such period any
Person that subsequently became a Restricted Subsidiary or was merged with or
into Holdings or any Restricted Subsidiary since the beginning of such period
shall have made any Investment, acquisition, disposition, merger, consolidation
or discontinued operation, in each case with respect to an operating unit of a
business, that would have required adjustment pursuant to this definition, then
the Secured Indebtedness Leverage Ratio shall be calculated giving pro forma
effect thereto for such period as if such Investment, acquisition, disposition,
discontinued operation, merger or consolidation had occurred at the beginning of

given to any transaction, the pro forma calculations shall be made in good faith
by a responsible financial or accounting officer of the Company. Any such pro
forma calculation may include adjustments appropriate, in the reasonable
determination of the Company as set forth in an Officers' Certificate, to

hereby incorporated in and expressly made a part of this Indenture. The (i)
Initial Dollar Securities and the Trustee's certificate of authentication and
(ii) any Additional Dollar Securities (if issued as Transfer Restricted Dollar
Securities) and the Trustee's certificate of authentication shall each be
substantially in the form of Exhibit A hereto, which is hereby incorporated in
and expressly made a part of this Indenture. The (i) Initial Euro Securities and
the Trustee's certificate of authentication and (ii) any Additional Euro
Securities (if issued as Transfer Restricted Securities) and the Trustee's
certificate of authentication shall each be substantially in the form of Exhibit
B hereto, which is hereby incorporated in and expressly made a part of this
Indenture. The (i) Exchange Dollar Securities and the Trustee's certificate of
authentication and (ii) any Additional Dollar Securities issued other than as
Transfer Restricted Securities and the Trustee's certificate of authentication
shall each be substantially in the form of Exhibit C hereto, which is hereby
incorporated in and expressly made a part of this Indenture. The (i) Exchange
Euro Securities and the Trustee's certificate of authentication and (ii) any
Additional Euro Securities issued other than as Transfer Restricted Securities
and the Trustee's certificate of authentication shall each be substantially in
the form of Exhibit D hereto, which is hereby incorporated in and expressly made
a part of this Indenture. The Securities may have notations, legends or
endorsements required by law, stock exchange rule, agreements to which the
Company or any Guarantor is subject, if any, or usage (provided that any such
notation, legend or endorsement is in a form acceptable to the

                                      -37-

Company). Each Security shall be dated the date of its authentication. The
Securities shall be issuable only in registered form without interest coupons
and only in denominations of $1,000 in the case of Dollar Securities and
(euro)1,000 in the case of Euro Securities and any integral multiples thereof.

         SECTION 2.03. Execution and Authentication. The Trustee shall
authenticate and make available for delivery upon a written order of the Company
signed by one Officer (a) (i) Original Dollar Securities for original issue on
the date hereof in an aggregate principal amount of $665,000,000 and (ii)
Original Euro Securities for original issue on the date hereof in an aggregate
principal amount of (euro)200,000,000, (b) subject to the terms of this
Indenture, Additional Securities in an aggregate principal amount to be
determined at the time of issuance and specified therein and (c) the Exchange
Securities for issue in a Registered Exchange Offer pursuant to the Registration
Agreement for a like principal amount of Initial Securities exchanged pursuant
thereto or otherwise pursuant to an effective registration statement under the
Securities Act. Such order shall specify the amount of the Securities to be
authenticated, the date on which the original issue of Securities is to be
authenticated and whether the Securities are to be Initial Securities or
Exchange Securities. Notwithstanding anything to the contrary in the Indenture
or the Appendix, any issuance of Additional Securities after the Issue Date
shall be in a principal amount of at least $1,000 in the case of the Dollar
Securities and (euro)1,000 in the case of the Euro Securities, whether such
Additional Securities are of the same or a different series than the Original
Securities.

         One Officer shall sign the Securities for the Company by manual or
facsimile signature.

         If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

         A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

         The Trustee may appoint one or more authenticating agents reasonably
acceptable to the Company to authenticate the Securities. Any such appointment
shall be evidenced by an instrument signed by a Trust Officer, a copy of which
shall be furnished to the Company. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Registrar, Paying Agent or agent for service of notices and
demands.

         The Trustee is hereby authorized to enter into a letter of
representations with the Depository in the form provided by the Company and to
act in accordance with such letter.

                                      -38-

         SECTION 2.04. Registrar and Paying Agent. (a) The Company shall
maintain (i) an office or agency where Securities may be presented for
registration of transfer or for exchange (the "Registrar"), (ii) an office or
agency in the Borough of Manhattan, the City of New York, the State of New York
where Dollar Securities may be presented for payment (the "Dollar Paying
Agent"), (iii) an office or agency in the Borough of Manhattan, The City of New
York, the State of New York and London, England where Euro Securities may be
presented for payment (the "Euro Paying Agent") and (iv) so long as the Euro
Securities are listed on the Luxembourg Stock Exchange and if required by the
rules of the Luxembourg Stock Exchange, an office or agency in Luxembourg where
Euro Securities may be presented for payment (the "Luxembourg Paying Agent").
The Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company may have one or more co-registrars and one or more
additional paying agents. The term "Registrar" includes any co-registrars. The
Company shall maintain a co-registrar in London, England and, so long as the
Euro Securities are listed on the Luxembourg Stock Exchange and if required by
the rules of the Luxembourg Stock Exchange, in Luxembourg where Euro Securities
may be presented for registration of transfer or for exchange. The term "Paying
Agent" includes the Dollar Paying Agent, the Euro Paying Agent, the Luxembourg
Paying Agent (if any) and any additional paying agents. The Company initially
appoints the Trustee as (i) Registrar, Dollar Paying Agent and Euro Paying Agent
in connection with the Securities and (ii) the Securities Custodian with respect
to the Global Securities. The Company initially appoints The Bank of New York,
London Branch as co-registrar and Euro Paying Agent.

         (b) The Company shall enter into an appropriate agency agreement with
any Registrar or Paying Agent not a party to this Indenture, which shall
incorporate the terms of the TIA; provided that any such agency agreement with
the Luxembourg Paying Agent need not incorporate the provisions of the TIA. The
agreement shall implement the provisions of this Indenture that relate to such
agent. The Company shall notify the Trustee of the name and address of any such
agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee
shall act as such and shall be entitled to appropriate compensation therefor
pursuant to Section 7.07. The Company or any of its domestically organized
Wholly Owned Subsidiaries may act as Paying Agent or Registrar.

         (c) The Company may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Trustee; provided, however,
that no such removal shall become effective until (i) if applicable, acceptance
of an appointment by a successor as evidenced by an appropriate agreement
entered into by the Company and such successor Registrar or Paying Agent, as the
case may be, and delivered to the Trustee or (ii) notification to the Trustee
that the Trustee shall serve as Registrar or Paying Agent until the appointment
of a successor in accordance with clause (i) above. The Registrar or Paying
Agent may resign at any time upon written notice to the Company and the Trustee;
provided, however, that the Trustee may resign as Paying Agent or Registrar only
if the Trustee also resigns as Trustee in accordance with Section 7.08.

         SECTION 2.05. Paying Agent to Hold Money in Trust. Prior to each due
date of the principal of and interest on any Security, the Company shall deposit
with each Paying Agent (or if the Company or a Wholly Owned Subsidiary is acting
as Paying Agent,

                                      -39-

segregate and hold in trust for the benefit of the Persons entitled thereto) a
sum sufficient to pay such principal and interest when so becoming due. The
Company shall require each Paying Agent (other than the Trustee) to agree in
writing that a Paying Agent shall hold in trust for the benefit of Holders or
the Trustee all money held by a Paying Agent for the payment of principal of and
interest on the Securities, and shall notify the Trustee of any default by the
Company in making any such payment. If the Company or a Wholly Owned Subsidiary
of the Company acts as Paying Agent, it shall segregate the money held by it as
Paying Agent and hold it in trust for the benefit of the Persons entitled
thereto. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed by such Paying
Agent. Upon complying with this Section, a Paying Agent shall have no further
liability for the money delivered to the Trustee.

         SECTION 2.06. Holder Lists. The Trustee shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders. If the Trustee is not the Registrar, the Company
shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at
least five Business Days before each interest payment date and at such other
times as the Trustee may request in writing, a list in such form and as of such
date as the Trustee may reasonably require of the names and addresses of
Holders.

         SECTION 2.07. Transfer and Exchange. The Securities shall be issued in
registered form and shall be transferable only upon the surrender of a Security
for registration of transfer and in compliance with the Appendix. When a
Security is presented to the Registrar with a request to register a transfer,
the Registrar shall register the transfer as requested if its requirements
therefor are met. When Securities are presented to the Registrar with a request
to exchange them for an equal principal amount of Securities of other
denominations, the Registrar shall make the exchange as requested if the same
requirements are met. To permit registration of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Securities at the
Registrar's request. The Company may require payment of a sum sufficient to pay
all taxes, assessments or other governmental charges in connection with any
transfer or exchange pursuant to this Section. The Company shall not be required
to make, and the Registrar need not register, transfers or exchanges of
Securities selected for redemption (except, in the case of Securities to be
redeemed in part, the portion thereof not to be redeemed) or of any Securities
for a period of 15 days before a selection of Securities to be redeemed.

         Prior to the due presentation for registration of transfer of any
Security, the Company, the Guarantors, the Trustee, each Paying Agent and the
Registrar may deem and treat the Person in whose name a Security is registered
as the absolute owner of such Security for the purpose of receiving payment of
principal of and interest, if any, on such Security and for all other purposes
whatsoever, whether or not such Security is overdue, and none of the Company,
any Guarantor, the Trustee, a Paying Agent or the Registrar shall be affected by
notice to the contrary.

         Any Holder of a beneficial interest in a Global Security shall, by
acceptance of such beneficial interest, agree that transfers of beneficial
interests in such Global Security

                                      -40-

may be effected only through a book-entry system maintained by (a) the Holder of
such Global Security (or its agent) or (b) any Holder of a beneficial interest
in such Global Security, and that ownership of a beneficial interest in such
Global Security shall be required to be reflected in a book entry.

         All Securities issued upon any transfer or exchange pursuant to the
terms of this Indenture shall evidence the same debt and shall be entitled to
the same benefits under this Indenture as the Securities surrendered upon such
transfer or exchange.

         SECTION 2.08. Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a)
satisfies the Company or the Trustee within a reasonable time after such Holder
has notice of such loss, destruction or wrongful taking and the Registrar does
not register a transfer prior to receiving such notification, (b) makes such
request to the Company or the Trustee prior to the Security being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code
(a "protected purchaser") and (c) satisfies any other reasonable requirements of
the Trustee. If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Trustee to protect
the Company, the Trustee, a Paying Agent and the Registrar from any loss that
any of them may suffer if a Security is replaced. The Company and the Trustee
may charge the Holder for their expenses in replacing a Security (including,
without limitation, attorneys' fees and disbursements in replacing such
Security). In the event any such mutilated, lost, destroyed or wrongfully taken
Security has become or is about to become due and payable, the Company in its
discretion may pay such Security instead of issuing a new Security in
replacement thereof.

         Every replacement Security is an additional obligation of the Company.

         The provisions of this Section 2.08 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

         SECTION 2.09. Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding. Subject to Section 11.06, a Security does not cease
to be outstanding because the Company or an Affiliate of the Company holds the
Security.

         If a Security is replaced pursuant to Section 2.08 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee and the Company receive proof satisfactory to them that the
replaced Security is held by a protected purchaser. A mutilated Security ceases
to be outstanding upon surrender of such Security and replacement thereof
pursuant to Section 2.08.

                                      -41-

         If a Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal and interest payable on that date with respect to the Securities
(or portions thereof) to be redeemed or maturing, as the case may be, and no
Paying Agent is prohibited from paying such money to the Holders on that date
pursuant to the terms of this Indenture, then on and after that date such
Securities (or portions thereof) cease to be outstanding and interest on them
ceases to accrue.

         SECTION 2.10. Temporary Securities. In the event that Definitive
Securities are to be issued under the terms of this Indenture, until such
Definitive Securities are ready for delivery, the Company may prepare and the
Trustee shall authenticate temporary Securities. Temporary Securities shall be
substantially in the form of Definitive Securities but may have variations that
the Company considers appropriate for temporary Securities. Without unreasonable
delay, the Company shall prepare and the Trustee shall authenticate Definitive
Securities and make them available for delivery in exchange for temporary
Securities upon surrender of such temporary Securities at the office or agency
of the Company, without charge to the Holder. Until such exchange, temporary
Securities shall be entitled to the same rights, benefits and privileges as
Definitive Securities.

         SECTION 2.11. Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and each Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and shall dispose of canceled Securities in accordance with its
customary procedures or deliver canceled Securities to the Company pursuant to
written direction by an Officer. The Company may not issue new Securities to
replace Securities it has redeemed, paid or delivered to the Trustee for
cancellation. The Trustee shall not authenticate Securities in place of canceled
Securities other than pursuant to the terms of this Indenture.

         SECTION 2.12. Defaulted Interest. If the Company defaults in a payment
of interest on the Dollar Securities or the Euro Securities, the Company shall
pay the defaulted interest then borne by the Dollar Securities or the Euro
Securities, as the case may be (plus interest on such defaulted interest to the
extent lawful), in any lawful manner. The Company may pay the defaulted interest
to the Persons who are Holders on a subsequent special record date. The Company
shall fix or cause to be fixed any such special record date and payment date to
the reasonable satisfaction of the Trustee and shall promptly mail or cause to
be mailed to each affected Holder a notice that states the special record date,
the payment date and the amount of defaulted interest to be paid.

         SECTION 2.13. CUSIP Numbers, ISINs, etc. The Company in issuing the
Securities may use CUSIP numbers, ISINs and "Common Code" numbers (if then
generally in use) and, if so, the Trustee shall use CUSIP numbers, ISINs and
"Common Code" numbers in notices of redemption as a convenience to Holders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers, either as printed on the Securities or as
contained in any notice of a redemption, that reliance may be

                                      -42-

placed only on the other identification numbers printed on the Securities and
that any such redemption shall not be affected by any defect in or omission of
such numbers. The Company shall advise the Trustee of any change in the CUSIP
numbers, ISINs and "Common Code" numbers.

         SECTION 2.14. Calculation of Principal Amount of Securities. The
aggregate principal amount of the Securities, at any date of determination,
shall be the sum of (1) the principal amount of the Dollar Securities at such
date of determination plus (2) the U.S. Dollar Equivalent, at such date of
determination, of the principal amount of the Euro Securities at such date of
determination. With respect to any matter requiring consent, waiver, approval or
other action of the Holders of a specified percentage of the principal amount of
all the Securities (and not solely the Dollar Securities or the Euro Securities
as provided for in the proviso to the first sentence of Section 9.02(a)), such
percentage shall be calculated, on the relevant date of determination, by
dividing (a) the principal amount, as of such date of determination, of
Securities, the Holders of which have so consented by (b) the aggregate
principal amount, as of such date of determination, of the Securities then
outstanding, in each case, as determined in accordance with the preceding
sentence, Section 2.09 and Section 11.06 of this Indenture. Any such calculation
made pursuant to this Section 2.14 shall be made by the Company and delivered to
the Trustee pursuant to an Officers' Certificate.

                                   ARTICLE 3

                                   REDEMPTION

         SECTION 3.01. Redemption. The Securities may be redeemed, in whole, or
from time to time in part, subject to the conditions and at the redemption
prices set forth in Paragraph 5 of the form of Securities set forth in Exhibit
A, Exhibit B, Exhibit C and Exhibit D hereto, which are hereby incorporated by
reference and made a part of this Indenture, together with accrued and unpaid
interest to the redemption date.

         SECTION 3.02. Applicability of Article. Redemption of Securities at the
election of the Company or otherwise, as permitted or required by any provision
of this Indenture, shall be made in accordance with such provision and this
Article.

         SECTION 3.03. Notices to Trustee. If the Company elects to redeem
Dollar Securities and/or Euro Securities pursuant to the optional redemption
provisions of Paragraph 5 of the applicable Security, it shall notify the
Trustee in writing of (i) the Section of this Indenture pursuant to which the
redemption shall occur, (ii) the redemption date, (iii) the principal amount of
Dollar Securities and/or Euro Securities to be redeemed and (iv) the redemption
price. The Company shall give notice to the Trustee provided for in this
paragraph at least 40 days but not more than 60 days before a redemption date if
the redemption is pursuant to Paragraph 5 of the applicable Security, unless a
shorter period is acceptable to the Trustee. Such notice shall be accompanied by
an Officers' Certificate and Opinion of Counsel from the Company to the effect
that such redemption will comply with the conditions herein. If fewer than all
the Dollar Securities and/or Euro Securities are to be

                                      -43-

redeemed, the record date relating to such redemption shall be selected by the
Company and given to the Trustee, which record date shall be not fewer than 15
days after the date of notice to the Trustee. Any such notice may be canceled at
any time prior to notice of such redemption being mailed to any Holder and shall
thereby be void and of no effect.

         SECTION 3.04. Selection of Securities to Be Redeemed. In the case of
any partial redemption, selection of the Securities for redemption will be made
by the Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which such Securities are listed, or if such
Securities are not so listed, on a pro rata basis, by lot or by such other
method as the Trustee shall deem fair and appropriate (and in such manner as
complies with applicable legal requirements); provided that no Dollar Securities
of $1,000 or less, or Euro Securities of (euro)1,000 or less, shall be redeemed
in part. The Trustee shall make the selection from outstanding Securities not
previously called for redemption. The Trustee may select for redemption portions
of the principal of Securities that have denominations larger than $1,000 in the
case of Dollar Securities or (euro)1,000 in the case of Euro Securities,
respectively. Securities and portions of them the Trustee selects shall be in
amounts of $1,000 in the case of Dollar Securities or (euro)1,000 in the case of
Euro Securities or a whole multiple of $1,000 in the case of Dollar Securities
or (euro)1,000 in the case of Euro Securities, respectively. Provisions of this
Indenture that apply to Securities called for redemption also apply to portions
of Securities called for redemption. The Trustee shall notify the Company
promptly of the Securities or portions of Securities to be redeemed.

         SECTION 3.05. Notice of Optional Redemption. (a) At least 30 days but
not more than 60 days before a redemption date pursuant to Paragraph 5 of the
applicable Security, the Company shall mail or cause to be mailed by first-class
mail a notice of redemption to each Holder whose Securities are to be redeemed.

         Any such notice shall identify the Dollar Securities and/or Euro
Securities to be redeemed and shall state:

                  (i) the redemption date;

                  (ii) the redemption price and the amount of accrued interest
         to the redemption date;

                  (iii) the name and address of a Paying Agent;

                  (iv) that Securities called for redemption must be surrendered
         to a Paying Agent to collect the redemption price, plus accrued
         interest;

                  (v) if fewer than all the outstanding Securities are to be
         redeemed, the certificate numbers and principal amounts of the
         particular Securities to be redeemed, the aggregate principal amount of
         Securities to be redeemed and the aggregate principal amount of
         Securities to be outstanding after such partial redemption;

                  (vi) that, unless the Company defaults in making such
         redemption payment or any Paying Agent is prohibited from making such
         payment pursuant to the terms of

                                      -44-

         this Indenture, interest on Securities (or portion thereof) called for
         redemption ceases to accrue on and after the redemption date;

                  (vii) the CUSIP number, ISIN and/or "Common Code" number, if
         any, printed on the Securities being redeemed; and

                  (viii) that no representation is made as to the correctness or
         accuracy of the CUSIP number or ISIN and/or "Common Code" number, if
         any, listed in such notice or printed on the Securities.

         (b) At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section.

         SECTION 3.06. Effect of Notice of Redemption. Once notice of redemption
is mailed in accordance with Section 3.05, Securities called for redemption
become due and payable on the redemption date and at the redemption price stated
in the notice. Upon surrender to any Paying Agent, such Securities shall be paid
at the redemption price stated in the notice, plus accrued interest to the
redemption date; provided, however, that if the redemption date is after a
regular record date and on or prior to the interest payment date, the accrued
interest shall be payable to the Holder of the redeemed Securities registered on
the relevant record date. Failure to give notice or any defect in the notice to
any Holder shall not affect the validity of the notice to any other Holder.

         SECTION 3.07. Deposit of Redemption Price. (a) With respect to any
Dollar Securities, prior to 10:00 a.m., New York City time, on the redemption
date, the Company shall deposit with the Dollar Paying Agent (or, if the Company
or a Wholly Owned Subsidiary is a Paying Agent, shall segregate and hold in
trust) money sufficient to pay the redemption price of and accrued interest on
all Dollar Securities or portions thereof to be redeemed on that date other than
Dollar Securities or portions of Dollar Securities called for redemption that
have been delivered by the Company to the Trustee for cancellation. On and after
the redemption date, interest shall cease to accrue on Dollar Securities or
portions thereof called for redemption so long as the Company has deposited with
the Dollar Paying Agent funds sufficient to pay the principal of, plus accrued
and unpaid interest on, the Dollar Securities to be redeemed, unless a Paying
Agent is prohibited from making such payment pursuant to the terms of this
Indenture.

         (b) With respect to the Euro Securities, prior to 10:00 a.m., London
time, on the redemption date, the Company shall deposit with the Euro Paying
Agent (or, if the Company or a Wholly Owned Subsidiary is a Paying Agent, shall
segregate and hold in trust) money sufficient to pay the redemption price of and
accrued interest on all Euro Securities or portions thereof to be redeemed on
that date other than Euro Securities or portions of Euro Securities called for
redemption that have been delivered by the Company to the Trustee for
cancellation. On and after the redemption date, interest shall cease to accrue
on Euro Securities or portions thereof called for redemption so long as the
Company has deposited with the Euro Paying Agent funds sufficient to pay the
principal of, plus accrued and unpaid

                                      -45-

interest on, the Euro Securities to be redeemed, unless the Euro Paying Agent is
prohibited from making such payment pursuant to the terms of this Indenture.

         SECTION 3.08. Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate for the Holder (at the Company's expense) a new Security equal in
principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE 4

                                    COVENANTS

         SECTION 4.01. Payment of Securities. The Company shall promptly pay the
principal of and interest, on the Securities on the dates and in the manner
provided in the Securities and in this Indenture. An installment of principal of
or interest shall be considered paid on the date due if on such date the Trustee
or any Paying Agent holds in accordance with this Indenture money sufficient to
pay all principal and interest then due and the Trustee or any Paying Agent, as
the case may be, are not prohibited from paying such money to the Holders on
that date pursuant to the terms of this Indenture.

         The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate borne by the Securities to the extent
lawful.

         SECTION 4.02. Reports and Other Information. Notwithstanding that
Holdings may not be subject to the reporting requirements of Section 13 or 15(d)
of the Exchange Act, or otherwise report on an annual and quarterly basis on
forms provided for such annual and quarterly reporting pursuant to rules and
regulations promulgated by the SEC, Holdings shall file with the SEC (and
provide the Trustee and Holders with copies thereof, without cost to each
Holder, within 15 days after it files them with the SEC),

                  (a) within 90 days after the end of each fiscal year (or such
         shorter period as may be required by the SEC), annual reports on Form
         10K (or any successor or comparable form) containing the information
         required to be contained therein (or required in such successor or
         comparable form),

                  (b) within 45 days after the end of each of the first three
         fiscal quarters of each fiscal year (or such shorter period as may be
         required by the SEC), reports on Form 10Q (or any successor or
         comparable form),

                  (c) promptly from time to time after the occurrence of an
         event required to be therein reported (and in any event within the time
         period specified for filing current reports on Form 8K by the SEC),
         such other reports on Form 8K (or any successor or comparable form),
         and

                                      -46-

                  (d) any other information, documents and other reports which
         Holdings would be required to file with the SEC if it were subject to
         Section 13 or 15(d) of the Exchange Act;

provided, however, that Holdings shall not be so obligated to file such reports
with the SEC if the SEC does not permit such filing, in which event Holdings
shall make available such information to prospective purchasers of Securities,
in addition to providing such information to the Trustee and the Holders, in
each case within 15 days after the time Holdings would be required to file such
information with the SEC if it were subject to Section 13 or 15(d) of the
Exchange Act; provided, further, that notwithstanding the foregoing (i) with
respect to the fiscal quarter ended September 30, 2003, Holdings may deliver to
the Trustee the report described in clause (b) above at any time on or prior to
December 31, 2003, (ii) with respect to the full fiscal year ending December 31,
2003, Holdings may deliver to the Trustee the report described in clause (a)
above at any time on or prior to April 30, 2004 and, in each case, such reports
may (x) exclude the guarantor footnote disclosure required under Rule 3-10 of
Regulation S-X and (y) indicate that the purchase accounting therein is
reflected on a preliminary basis and is subject to change and (iii) with respect
to reports that Holdings is not required to file with the SEC pursuant to the
immediately preceding proviso, if the Company and the Guarantors have not at
such time failed to comply with their obligations to consummate an exchange
offer (or a shelf registration, if applicable) pursuant to the Registration
Agreement, such reports need not include any financial statements for full
fiscal years ended on or prior to December 31, 2002 other than such financial
statements included in the Offering Memorandum.

         In the event that:

                  (i) the rules and regulations of the SEC permit Holdings and
         any direct or indirect parent company of Holdings to report at such
         parent entity's level on a consolidated basis and

                  (ii) such parent entity of Holdings is not engaged in any
         business in any material respect other than incidental to its
         ownership, directly or indirectly, of the capital stock of Holdings,

such consolidated reporting at such parent entity's level in a manner consistent
with that described in this Section 4.02 for Holdings shall satisfy this Section
4.02.

         Holdings and the Company shall also furnish to Holders, securities
analysts and prospective investors upon request the information required to be
delivered pursuant to Rule 144 and Rule 144A(d)(4) under the Securities Act (it
being acknowledged and agreed that, prior to the first date on which information
is required to be provided under this Section 4.02, the information contained in
the Offering Memorandum is sufficient for this purpose).

         Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained

                                      -47-

therein or determinable from information contained therein, including the
Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively (subject to Article 7 hereof) on
Officers' Certificates).

SECTION 4.03. Limitation on Incurrence of Indebtedness and Issuance of
Disqualified Stock and Preferred Stock. (a) (i) Holdings shall not, and shall
not permit any of its Restricted Subsidiaries to, directly or indirectly, Incur
any Indebtedness (including Acquired Indebtedness) or issue any shares of
Disqualified Stock; and (ii) Holdings shall not permit any of its Restricted
Subsidiaries to issue any shares of Preferred Stock; provided, however, that the
Company and Holdings and any Restricted Subsidiary that is a Guarantor may Incur
Indebtedness (including Acquired Indebtedness) or issue shares of Disqualified
Stock and the Company and Holdings and any Restricted Subsidiary that is a
Guarantor may issue shares of Preferred Stock, in each case if the Fixed Charge
Coverage Ratio of Holdings for the most recently ended four full fiscal quarters
for which internal financial statements are available immediately preceding the
date on which such additional Indebtedness is Incurred or such Disqualified
Stock or Preferred Stock is issued would have been at least 2.00 to 1.00
determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been Incurred, or the
Disqualified Stock or Preferred Stock had been issued, as the case may be, and
the application of proceeds therefrom had occurred at the beginning of such
four-quarter period.

         (b) The limitations set forth in Section 4.03(a) shall not apply to:

                  (i) the Incurrence by Holdings or its Restricted Subsidiaries
         of Indebtedness under the Credit Agreement and the issuance and
         creation of letters of credit and bankers' acceptances thereunder (with
         letters of credit and bankers' acceptances being deemed to have a
         principal amount equal to the face amount thereof) up to an aggregate
         principal amount of $1,950 million outstanding at any one time, less
         the amount of any such Indebtedness permanently retired with the Net
         Proceeds from any Asset Sale applied from and after the Issue Date to
         reduce the outstanding amounts pursuant to Section 4.06;

                  (ii) the Incurrence by the Company and the Guarantors of
         Indebtedness represented by (A) the Original Securities and the Senior
         Guarantees, as applicable, (B) the Exchange Securities issued in
         exchange for the Original Securities and the Senior Guarantees thereof,
         and (C) the Senior Subordinated Notes and the related guarantees, as
         applicable;

                  (iii) Indebtedness existing on the Issue Date (other than

         4.03(b));

                  (iv) Indebtedness (including Capitalized Lease Obligations)
         Incurred by Holdings or any of its Restricted Subsidiaries to finance

         equipment (whether through the direct purchase of assets or the Capital
         Stock of any Person owning such assets (but no other material assets))
         in an aggregate principal amount which, when aggregated with the

                                      -48-

         principal amount of all other Indebtedness then outstanding that was
         Incurred pursuant to this clause (iv), does not exceed 3% of Total
         Assets at the time of Incurrence;

                  (v) Indebtedness Incurred by Holdings or any of its Restricted
         Subsidiaries constituting reimbursement obligations with respect to

         compensation claims, health, disability or other employee benefits or
         property, casualty or liability insurance or self-insurance, or other
         Indebtedness with respect to reimbursement type obligations regarding
         workers' compensation claims; provided, however, that upon the drawing
         of such letters of credit, such obligations are reimbursed within 30
         days following such drawing;

                  (vi) Indebtedness arising from agreements of Holdings or a
         Restricted Subsidiary providing for indemnification, adjustment of
         purchase price or similar obligations, in each case, Incurred in
         connection with the disposition of any business, assets or a Subsidiary
         of Holdings in accordance with the terms of this Indenture, other than
         guarantees of Indebtedness Incurred by any Person acquiring all or any
         portion of such business, assets or Subsidiary for the purpose of
         financing such acquisition;

                  (vii) Indebtedness of Holdings to a Restricted Subsidiary;
         provided that any such Indebtedness is subordinated in right of payment
         to the obligations of Holdings under its Senior Guarantee; provided,
         further, that any subsequent issuance or transfer of any Capital Stock
         or any other event which results in any such Restricted Subsidiary
         ceasing to be a Restricted Subsidiary or any other subsequent transfer
         of any such Indebtedness (except to Holdings or another Restricted
         Subsidiary) shall be deemed, in each case, to be an Incurrence of such
         Indebtedness;

                  (viii) shares of Preferred Stock of a Restricted Subsidiary
         issued to Holdings or another Restricted Subsidiary; provided that any
         subsequent issuance or transfer of any Capital Stock or any other event
         which results in any Restricted Subsidiary that holds such shares of
         Preferred Stock of another Restricted Subsidiary ceasing to be a
         Restricted Subsidiary or any other subsequent transfer of any such
         shares of Preferred Stock (except to Holdings or another Restricted

                  (ix) Indebtedness of a Restricted Subsidiary to Holdings or
         another Restricted Subsidiary; provided that (1) any such Indebtedness
         is made pursuant to an intercompany note and (2) if a Guarantor Incurs

         such Indebtedness is subordinated in right of payment to the Senior
         Guarantee of such Guarantor; provided, further, that any subsequent
         issuance or transfer of any Capital Stock or any other event which
         results in any Restricted Subsidiary lending such Indebtedness ceasing
         to be a Restricted Subsidiary or any other subsequent transfer of any
         such Indebtedness (except to Holdings or another Restricted Subsidiary)
         shall be deemed, in each case, to be an Incurrence of such
         Indebtedness;

                                      -49-

                  (x) Hedging Obligations that are Incurred in the ordinary
         course of business (and not for speculative purposes): (1) for the
         purpose of fixing or hedging interest rate risk with respect to any
         Indebtedness that is permitted by the terms of this Indenture to be
         outstanding; (2) for the purpose of fixing or hedging currency exchange
         rate risk with respect to any currency exchanges; or (3) for the

         amount or liquidation preference of all other Indebtedness and
         Disqualified Stock then outstanding and Incurred pursuant to this
         clause (xii), does not exceed $175 million at any one time outstanding
         (it being understood that any Indebtedness Incurred under this clause
         (xii) shall cease to be deemed Incurred or outstanding for purposes of
         this clause (xii) but shall be deemed Incurred for purposes of Section
         4.03(a) from and after the first date on which Holdings, or the
         Restricted Subsidiary, as the case may be, could have Incurred such
         Indebtedness under Section 4.03(a) without reliance upon this clause
         (xii));

                  (xiii) any guarantee by the Company or a Guarantor of
         Indebtedness or other obligations of Holdings or any of its Restricted
         Subsidiaries so long as the Incurrence of such Indebtedness Incurred by
         Holdings or such Restricted Subsidiary is permitted under the terms of
         this Indenture; provided that if such Indebtedness is by its express
         terms subordinated in right of payment to the Securities or the Senior
         Guarantee of such Restricted Subsidiary, as applicable, any such
         guarantee of such Guarantor with respect to such Indebtedness shall be
         subordinated in right of payment to such Guarantor's Senior Guarantee
         with respect to the Securities substantially to the same extent as such
         Indebtedness is subordinated to the Securities or the Senior Guarantee
         of such Restricted Subsidiary, as applicable;

                  (xiv) the Incurrence by Holdings or any of its Restricted
         Subsidiaries of Indebtedness which serves to refund or refinance any
         Indebtedness Incurred as permitted under Section 4.03(a) and clauses
         (ii), (iii), (iv), (xv) and (xx) of this Section 4.03(b) or any
         Indebtedness issued to so refund or refinance such Indebtedness
         (subject to the following proviso, "Refinancing Indebtedness") prior to
         its respective maturity; provided, however, that such Refinancing
         Indebtedness:

                           (1) has a Weighted Average Life to Maturity at the
                  time such Refinancing Indebtedness is Incurred which is not
                  less than the remaining Weighted Average Life to Maturity of
                  the Indebtedness being refunded or refinanced;

                                      -50-

                           (2) has a Stated Maturity which is no earlier than
                  the Stated Maturity of the Indebtedness being refunded or
                  refinanced;

                           (3) to the extent such Refinancing Indebtedness
                  refinances Indebtedness junior to the Securities or the Senior
                  Guarantee of such Restricted Subsidiary, as applicable, such
                  Refinancing Indebtedness is junior to the Securities or the
                  Senior Guarantee of such Restricted Subsidiary, as applicable;

                           (4) is Incurred in an aggregate principal amount (or
                  if issued with original issue discount, an aggregate issue
                  price) that is equal to or less than the aggregate principal
                  amount (or if issued with original issue discount, the
                  aggregate accreted value) then outstanding of the Indebtedness
                  being refinanced plus premium and fees Incurred in connection
                  with such refinancing;

                           (5) shall not include (x) Indebtedness of a
                  Restricted Subsidiary of Holdings that is not the Company or a
                  Guarantor that refinances Indebtedness of the Company or a
                  Guarantor, or (y) Indebtedness of Holdings or a Restricted
                  Subsidiary that refinances Indebtedness of an Unrestricted
                  Subsidiary; and

                           (6) in the case of any Refinancing Indebtedness
                  Incurred to refinance Indebtedness outstanding under clause
                  (iv) or (xx) of this Section 4.03(b), shall be deemed to have
                  been Incurred and to be outstanding under such clause (iv) or
                  (xx) of this Section 4.03(b), as applicable, and not this
                  clause (xiv) for purposes of determining amounts outstanding
                  under such clauses (iv) and (xx) of this Section 4.03(b);

         provided, further, that subclauses (1) and (2) of this clause (xiv)
         shall not apply to any refunding or refinancing of any Secured
         Indebtedness;

                  (xv) Indebtedness or Disqualified Stock of Persons that are
         acquired by Holdings or any of its Restricted Subsidiaries or merged
         into a Restricted Subsidiary in accordance with the terms of this
         Indenture; provided, however, that such Indebtedness or Disqualified
         Stock is not Incurred in contemplation of such acquisition or merger or
         to provide all or a portion of the funds or credit support required to
         consummate such acquisition or merger; provided, further, however, that
         after giving effect to such acquisition and the Incurrence of such
         Indebtedness either:

                           (1) Holdings would be permitted to Incur at least
                  $1.00 of additional Indebtedness pursuant to the Fixed Charge
                  Coverage Ratio test set forth in Section 4.03(a); or

                           (2) the Fixed Charge Coverage Ratio would be greater
                  than immediately prior to such acquisition;

                                      -51-

                  (xvi) Indebtedness Incurred by a Receivables Subsidiary in a
         Qualified Receivables Financing that is not recourse to Holdings or any
         Restricted Subsidiary other than a Receivables Subsidiary (except for
         Standard Securitization Undertakings);

                  (xvii) Indebtedness arising from the honoring by a bank or
         other financial institution of a check, draft or similar instrument
         drawn against insufficient funds in the ordinary course of business;

         Days of its Incurrence;

                  (xviii) Indebtedness of Holdings or any Restricted Subsidiary
         supported by a letter of credit issued pursuant to the Credit
         Agreement, in a principal amount not in excess of the stated amount of
         such letter of credit;

                  (xix) Contribution Indebtedness;

                  (xx) (A) if Holdings could Incur $1.00 of additional
         Indebtedness pursuant to Section 4.03(a) after giving effect to such
         borrowing, Indebtedness of Foreign Subsidiaries not otherwise permitted
         hereunder or (B) if Holdings could not Incur $1.00 of additional
         Indebtedness pursuant to Section 4.03(a) after giving effect to such
         borrowing, Indebtedness of Foreign Subsidiaries of the Company Incurred
         for working capital purposes, provided, however, that the aggregate
         principal amount of Indebtedness Incurred under this clause (xx), when
         aggregated with the principal amount of all other Indebtedness then
         outstanding and Incurred pursuant to this clause (xx), does not exceed
         the greater of (x) $125 million and (y) 10% of the consolidated assets
         of the Foreign Subsidiaries; and

                  (xxi) Indebtedness of Holdings or any Restricted Subsidiary
         consisting of (x) the financing of insurance premiums or (y)
         take-or-pay obligations contained in supply arrangements, in each case,
         in the ordinary course of business.

         (c) Notwithstanding the foregoing, neither the Company nor any
Guarantor may Incur any Indebtedness pursuant to Section 4.03(b) if the proceeds
thereof are used, directly or indirectly, to repay, prepay, redeem, defease,
retire, refund or refinance any Subordinated Indebtedness unless such
Indebtedness shall be subordinated to the Securities or such Guarantor's Senior
Guarantee, as applicable, to at least the same extent as such Subordinated
Indebtedness. For purposes of determining compliance with this Section 4.03, in
the event that an item of Indebtedness meets the criteria of more than one of
the categories of permitted Indebtedness described in clauses (i) through (xxi)
above or is entitled to be Incurred pursuant to Section 4.03(a), Holdings shall,
in its sole discretion, classify or reclassify such item of Indebtedness in any
manner that complies with this Section 4.03 and such item of Indebtedness shall
be treated as having been Incurred pursuant to only one of such clauses or
pursuant to Section 4.03(a); provided that all Indebtedness under the Credit
Agreement outstanding on the Issue Date shall be deemed to have been Incurred
pursuant to clause (i) and Holdings shall not be permitted to reclassify all or
any portion of such Indebtedness. Accrual of interest, the accretion of accreted
value, the payment of interest in the form of additional Indebtedness with the
same terms, the payment of dividends on

                                      -52-

Preferred Stock in the form of additional shares of Preferred Stock of the same
class and increases in the amount of Indebtedness outstanding solely as a result
of fluctuations in the exchange rate of currencies shall not be deemed to be an
Incurrence of Indebtedness for purposes of this Section 4.03. Guarantees of, or
obligations in respect of letters of credit relating to, Indebtedness which are
otherwise included in the determination of a particular amount of Indebtedness
shall not be included in the determination of such amount of Indebtedness;
provided that the Incurrence of the Indebtedness represented by such guarantee
or letter of credit, as the case may be, was in compliance with this Section
4.03.

         SECTION 4.04. Limitation on Restricted Payments. (a)Holdings shall not,
and shall not permit any of its Restricted Subsidiaries to, directly or
indirectly:

                  (i) declare or pay any dividend or make any distribution on
         account of Holdings' or any of its Restricted Subsidiaries' Equity
         Interests, including any payment made in connection with any merger or
         consolidation involving Holdings (other than (A) dividends or
         distributions by Holdings payable solely in Equity Interests (other
         than Disqualified Stock) of Holdings; or (B) dividends or distributions

         distribution payable on or in respect of any class or series of
         securities issued by a Restricted Subsidiary other than a Wholly Owned
         Restricted Subsidiary, Holdings or a Restricted Subsidiary receives at
         least its pro rata share of such dividend or distribution in accordance
         with its Equity Interests in such class or series of securities);

                  (ii) purchase or otherwise acquire or retire for value any
         Equity Interests of Holdings, the Company or any direct or indirect
         parent company of Holdings or the Company;

                  (iii) make any principal payment on, or redeem, repurchase,
         defease or otherwise acquire or retire for value, in each case prior to
         any scheduled repayment or scheduled maturity, any Subordinated
         Indebtedness (other than the payment, redemption, repurchase,
         defeasance, acquisition or retirement of (A) Subordinated Indebtedness
         in anticipation of satisfying a sinking fund obligation, principal
         installment or final maturity, in each case due within one year of the
         date of such payment, redemption, repurchase, defeasance, acquisition
         or retirement and (B) Indebtedness permitted under clauses (vii) and
         (ix) of Section 4.03(b)); or

                  (iv) make any Restricted Investment

         any direct or indirect parent company of Holdings or the Company, as
         the case may be, or Restricted Subsidiaries of Holdings to Affiliates,
         in each case to the extent permitted by Section 4.07;

                  (xv) repurchases of Equity Interests deemed to occur upon

         of the Transactions or as contemplated by the Acquisition Documents
         (other than payments to any Permitted Holder or any Affiliate thereof);

provided, however, that at the time of, and after giving effect to, any

this Section 4.04(b), no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof.

Restricted Subsidiaries. Holdings shall not permit any Unrestricted Subsidiary
to become a Restricted

                                      -59-

Subsidiary except pursuant to the definition of "Unrestricted Subsidiary." For
purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary,
all outstanding Investments by Holdings and its Restricted Subsidiaries (except
to the extent repaid) in the Subsidiary so designated shall be deemed to be
Restricted Payments in an amount determined as set forth in the last sentence of
the definition of "Investments." Such designation shall only be permitted if a
Restricted Payment in such amount would be permitted at such time and if such
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.
Notwithstanding the foregoing, Holdings may not at any time designate the
Company as an Unrestricted Subsidiary for any purpose under this Indenture or
the Securities.

         SECTION 4.05. Dividend and Other Payment Restrictions Affecting
Subsidiaries. Holdings shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or consensual restriction
on the ability of any Restricted Subsidiary to:

                  (a) (i) pay dividends or make any other distributions to
         Holdings or any of its Restricted Subsidiaries (1) on its Capital
         Stock; or (2) with respect to any other interest or participation in,
         or by, its profits; or (ii) pay any Indebtedness owed to Holdings or
         any of its Restricted Subsidiaries;

                  (b) make loans or advances to Holdings or any of its
         Restricted Subsidiaries; or

                  (c) sell, lease or transfer any of its properties or assets to
         Holdings or any of its Restricted Subsidiaries;

except in each case for such encumbrances or restrictions existing under or by
reason of:

                  (1) contractual encumbrances or restrictions in effect on the
         Issue Date, including pursuant to the Credit Agreement and the other
         Senior Credit Documents;

                  (2) this Indenture, the Securities, the Senior Subordinated
         Notes and the indenture relating to the Senior Subordinated Notes;

                  (3) applicable law or any applicable rule, regulation or
         order;

                  (4) any agreement or other instrument relating to Indebtedness
         of a Person acquired by Holdings or any Restricted Subsidiary which was
         in existence at the time of such acquisition (but not created in
         contemplation thereof or to provide all or any portion of the funds or
         credit support utilized to consummate such acquisition), which
         encumbrance or restriction is not applicable to any Person, or the
         properties or assets of any Person, other than the Person, or the
         property or assets of the Person, so acquired;

                  (5) any restriction with respect to a Restricted Subsidiary
         imposed pursuant to an agreement entered into for the sale or
         disposition of all or substantially all the

                                      -60-

         Capital Stock or assets of such Restricted Subsidiary pending the
         closing of such sale or disposition;

                  (6) Secured Indebtedness otherwise permitted to be Incurred
         pursuant to Sections 4.03 and 4.12 that limit the right of the debtor
         to dispose of the assets securing such Indebtedness;

                  (7) restrictions on cash or other deposits or net worth
         imposed by customers under contracts entered into in the ordinary
         course of business;

                  (8) customary provisions in joint venture agreements and other
         similar agreements entered into in the ordinary course of business;

                  (9) purchase money obligations for property acquired in the
         ordinary course of business that impose restrictions of the nature
         discussed in clause (c) above on the property so acquired;

                  (10) customary provisions contained in leases and other
         similar agreements entered into in the ordinary course of business that
         impose restrictions of the type described in clause (c) above on the
         property subject to such lease;

                  (11) any encumbrance or restriction of a Receivables
         Subsidiary effected in connection with a Qualified Receivables
         Financing; provided, however, that such restrictions apply only to such
         Receivables Subsidiary;

                  (12) other Indebtedness of any Restricted Subsidiary of
         Holdings (i) that is the Company or a Guarantor that is Incurred
         subsequent to the Issue Date pursuant to Section 4.03 or (ii) that is
         Incurred by a Foreign Subsidiary of Holdings subsequent to the Issue
         Date pursuant to clauses (iv), (xii) or (xx) of Section 4.03(b); or

                  (13) any encumbrances or restrictions of the type referred to
         in clauses (a), (b) and (c) above imposed by any amendments,
         modifications, restatements, renewals, increases, supplements,
         refundings, replacements or refinancings of the contracts, instruments
         or obligations referred to in clauses (1) through (12) above; provided
         that such amendments, modifications, restatements, renewals, increases,
         supplements, refundings, replacements or refinancings are, in the good
         faith judgment of the Company, no more restrictive with respect to such
         dividend and other payment restrictions than those contained in the
         dividend or other payment restrictions prior to such amendment,
         modification, restatement, renewal, increase, supplement, refunding,
         replacement or refinancing.

         SECTION 4.06. Asset Sales. (a) Holdings shall not, and shall not permit
any of its Restricted Subsidiaries to, cause or make an Asset Sale, unless (x)
Holdings or any of its Restricted Subsidiaries, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value (as determined in good faith by the Company) of the assets sold or
otherwise disposed of and (y) at least 75% of the consideration

                                      -61-

therefor received by Holdings or such Restricted Subsidiary, as the case may be,
is in the form of Cash Equivalents; provided that the amount of:

                  (i) any liabilities (as shown on Holdings' or such Restricted
         Subsidiary's most recent balance sheet or in the notes thereto) of
         Holdings or any Restricted Subsidiary of Holdings (other than
         liabilities that are by their terms subordinated to the Securities)
         that are assumed by the transferee of any such assets,

                  (ii) any notes or other obligations or other securities or
         assets received by Holdings or such Restricted Subsidiary of Holdings
         from such transferee that are converted by Holdings or such Restricted
         Subsidiary of Holdings into cash within 180 days of the receipt thereof
         (to the extent of the cash received), and

                  (iii) any Designated Non-cash Consideration received by
         Holdings or any of its Restricted Subsidiaries in such Asset Sale
         having an aggregate Fair Market Value, taken together with all other
         Designated Non-cash Consideration received pursuant to this clause
         (iii) that is at that time outstanding, not to exceed the greater of 1%
         of Total Assets and $50 million at the time of the receipt of such
         Designated Non-cash Consideration (with the Fair Market Value of each
         item of Designated Non-cash Consideration being measured at the time
         received and without giving effect to subsequent changes in value)

shall be deemed to be Cash Equivalents for the purposes of this Section 4.06(a).

         (b) Within 365 days after Holdings' or any Restricted Subsidiary of
Holdings' receipt of the Net Proceeds of any Asset Sale, Holdings or such
Restricted Subsidiary may apply the Net Proceeds from such Asset Sale, at its
option:

                  (i) to permanently reduce Obligations under the Credit
         Agreement (and, in the case of revolving Obligations, to
         correspondingly reduce commitments with respect thereto) or other Pari
         Passu Indebtedness (provided that if the Company or any Guarantor shall
         so reduce Obligations under other Pari Passu Indebtedness, the Company
         shall equally and ratably reduce Obligations under the Securities by
         making an offer (in accordance with the procedures set forth below for
         an Asset Sale Offer) to all Holders to purchase at a purchase price
         equal to 100% of the principal amount thereof, plus accrued and unpaid
         interest the pro rata principal amount of Securities) or Indebtedness
         of a Restricted Subsidiary that is not a Guarantor, in each case other
         than Indebtedness owed to Holdings or an Affiliate of Holdings,

                  (ii) to an investment in any one or more businesses (provided
         that if such investment is in the form of the acquisition of Capital
         Stock of a Person, such acquisition results in such Person becoming a
         Restricted Subsidiary of Holdings), or capital expenditures, in each
         case used or useful in a Similar Business, and/or

                  (iii) to make an investment in any one or more businesses
         (provided that if such investment is in the form of the acquisition of
         Capital Stock of a Person, such acquisition results in such Person
         becoming a Restricted Subsidiary of Holdings),

                                      -62-

         properties or assets that replace the properties and assets that are
         the subject of such Asset Sale.

Pending the final application of any such Net Proceeds, Holdings or such
Restricted Subsidiary of Holdings may temporarily reduce Indebtedness under a
revolving credit facility, if any, or otherwise invest such Net Proceeds in Cash
Equivalents or Investment Grade Securities. Any Net Proceeds from any Asset Sale
that are not applied as provided and within the time period set forth in the
first sentence of this Section 4.06(b) (it being understood that any portion of
such Net Proceeds used to make an offer to purchase Securities, as described in
clause (i) above, shall be deemed to have been invested whether or not such
offer is accepted) shall be deemed to constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $20 million, the Company shall make
an offer to all Holders of Securities (an "Asset Sale Offer") to purchase the
maximum principal amount of Securities that is an integral multiple of $1,000 or
(euro)1,000, as applicable, that may be purchased out of the Excess Proceeds at
an offer price in cash in an amount equal to 100% of the principal amount
thereof, plus accrued and unpaid interest to the date fixed for the closing of
such offer, in accordance with the procedures set forth in this Section 4.06.
The Company shall commence an Asset Sale Offer with respect to Excess Proceeds
within ten Business Days after the date that Excess Proceeds exceeds $20 million
by mailing the notice required pursuant to the terms of Section 4.06(f), with a
copy to the Trustee. To the extent that the aggregate amount of Securities
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company may use any remaining Excess Proceeds for general corporate purposes. If
the aggregate principal amount of Securities surrendered by Holders thereof
exceeds the amount of Excess Proceeds, the Trustee shall select the Securities
to be purchased in the manner described in Section 4.06(e). Upon completion of
any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

         (c) The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations to the extent
such laws or regulations are applicable in connection with the repurchase of the
Securities pursuant to an Asset Sale Offer. To the extent that the provisions of
any securities laws or regulations conflict with the provisions of this
Indenture, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations described
in this Indenture by virtue thereof.

         (d) Not later than the date upon which written notice of an Asset Sale
Offer is delivered to the Trustee as provided above, the Company shall deliver
to the Trustee an Officers' Certificate as to (i) the amount of the Excess
Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant
to which such Asset Sale Offer is being made and (iii) the compliance of such
allocation with the provisions of Section 4.06(b). On such date, the Company
shall also irrevocably deposit with the Trustee or with a paying agent (or, if
the Company or a Wholly Owned Restricted Subsidiary is acting as a Paying Agent,
segregate and hold in trust) an amount equal to the Excess Proceeds to be
invested in Cash Equivalents, as directed in writing by the Company, and to be
held for payment in accordance with the provisions of this Section 4.06. Upon
the expiration of the period for which the Asset Sale Offer remains open (the
"Offer Period"), the Company shall deliver to the Trustee for

                                      -63-

cancellation the Securities or portions thereof that have been properly tendered
to and are to be accepted by the Company. The Trustee (or a Paying Agent, if not
the Trustee) shall, on the date of purchase, mail or deliver payment to each
tendering Holder in the amount of the purchase price. In the event that the
Excess Proceeds delivered by the Company to the Trustee is greater than the
purchase price of the Securities tendered, the Trustee shall deliver the excess
to the Company immediately after the expiration of the Offer Period for
application in accordance with Section 4.06.

         (e) Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
at the address specified in the notice at least three Business Days prior to the
purchase date. Holders shall be entitled to withdraw their election if the
Trustee or the Company receives not later than one Business Day prior to the
Purchase Date, a telegram, telex, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of the Security which was delivered
by the Holder for purchase and a statement that such Holder is withdrawing his
election to have such Security purchased. If at the end of the Offer Period more
Securities are tendered pursuant to an Asset Sale Offer than the Company is
required to purchase, selection of such Securities for purchase shall be made by
the Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which such Securities are listed, or if such
Securities are not so listed, on a pro rata basis, by lot or by such other
method as the Trustee shall deem fair and appropriate (and in such manner as
complies with applicable legal requirements); provided that no Dollar Securities
of $1,000 or less or Euro Securities of (euro)1,000 or less shall be purchased
in part.

         (f) Notices of an Asset Sale Offer shall be mailed by first class mail,
postage prepaid, at least 30 but not more than 60 days before the purchase date
to each Holder of Securities at such Holder's registered address. If any
Security is to be purchased in part only, any notice of purchase that relates to
such Security shall state the portion of the principal amount thereof that is to
be purchased. So long as the Securities are listed on the Luxembourg Stock
Exchange, such notices shall also be published in a Luxembourg newspaper of
general circulation.

         (g) A new Security in principal amount equal to the unpurchased portion
of any Security purchased in part shall be issued in the name of the Holder
thereof upon cancellation of the original Security. On and after the purchase
date, unless the Company defaults in payment of the purchase price, interest
shall cease to accrue on Securities or portions thereof purchased.

         SECTION 4.07. Transactions with Affiliates. (a) Holdings shall not, and
shall not permit any of its Restricted Subsidiaries to, directly or indirectly,
make any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any transaction or series of transactions, contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of Holdings (each of the foregoing, an "Affiliate Transaction")
involving aggregate consideration in excess of $5.0 million, unless:

                                      -64-

                  (i) such Affiliate Transaction is on terms that are not
         materially less favorable to Holdings or the relevant Restricted
         Subsidiary than those that could have been obtained in a comparable
         transaction by Holdings or such Restricted Subsidiary with an unrelated
         Person; and

                  (ii) with respect to any Affiliate Transaction or series of
         related Affiliate Transactions involving aggregate consideration in
         excess of $20 million, the Company delivers to the Trustee a resolution
         adopted in good faith by the majority of the Board of Directors of the
         Company or Holdings, approving such Affiliate Transaction and set forth
         in an Officers' Certificate certifying that such Affiliate Transaction
         complies with clause (i) above.

         (b) The provisions of Section 4.07(a) shall not apply to the following:

                  (i) (A) transactions between or among Holdings and/or any of
         its Restricted Subsidiaries and (B) any merger of Holdings and any
         direct parent company of Holdings; provided that such parent company
         shall have no material liabilities and no material assets other than
         cash, Cash Equivalents and the Capital Stock of Holdings and such
         merger is otherwise in compliance with the terms of this Indenture and
         effected for a bona fide business purpose;

                  (ii) Restricted Payments permitted by Section 4.04;

                  (iii) the entering into of any agreement to pay, and the
         payment of, annual management, consulting, monitoring and advisory fees
         and expenses to the Sponsors in an aggregate amount in any fiscal year
         not to exceed the greater of (x) $10 million and (y) 2% of EBITDA of
         Holdings and its Restricted Subsidiaries for the immediately preceding
         fiscal year;

                  (iv) the payment of reasonable and customary fees paid to, and
         indemnity provided on behalf of, officers, directors, employees or
         consultants of Holdings or any Restricted Subsidiary or any direct or
         indirect parent company of Holdings or the Company;

                  (v) payments by Holdings or any of its Restricted Subsidiaries
         to the Sponsors made for any financial advisory, financing,
         underwriting or placement services or in respect of other investment
         banking activities, including, without limitation, in connection with
         acquisitions or divestitures, which payments are approved by a majority
         of the Board of Directors of the Company or Holdings in good faith;

                  (vi) transactions in which Holdings or any of its Restricted
         Subsidiaries, as the case may be, delivers to the Trustee a letter from
         an Independent Financial Advisor stating that such transaction is fair
         to Holdings or such Restricted Subsidiary from a financial point of
         view or meets the requirements of clause (i) of Section 4.07(a);

                                      -65-

                  (vii) payments or loans to employees or consultants in the
         ordinary course of business which are approved by a majority of the
         Board of Directors of the Company or Holdings in good faith;

                  (viii) any agreement (other than with the Sponsors) as in
         effect as of the Issue Date or any amendment thereto (so long as any
         such agreement together with all amendments thereto, taken as a whole,
         is not more disadvantageous to the Holders of the Securities in any
         material respect than the original agreement as in effect on the Issue
         Date) or any transaction contemplated thereby;

                  (ix) the existence of, or the performance by Holdings or any
         of its Restricted Subsidiaries of its obligations under the terms of,
         Acquisition Documents, any stockholders agreement (including any
         registration rights agreement or purchase agreement related thereto) to
         which it is a party as of the Issue Date and any amendment thereto or
         similar agreements which it may enter into thereafter; provided,
         however, that the existence of, or the performance by Holdings or any
         of its Restricted Subsidiaries of its obligations under, any future
         amendment to any such existing agreement or under any similar agreement
         entered into after the Issue Date shall only be permitted by this
         clause (ix) to the extent that the terms of any such existing agreement
         together with all amendments thereto, taken as a whole, or new
         agreement are not otherwise more disadvantageous to the Holders of the
         Securities in any material respect than the original agreement as in
         effect on the Issue Date;

                  (x) the payment of all fees and expenses related to the
         Transactions, including fees to the Sponsors, which are described in
         the Offering Memorandum;

                  (xi) (A) transactions with customers, clients, suppliers or
         purchasers or sellers of goods or services, in each case in the
         ordinary course of business and otherwise in compliance with the terms
         of this Indenture, which are fair to Holdings and its Restricted
         Subsidiaries in the reasonable determination of the Board of Directors
         or the senior management of the Company, and are on terms at least as
         favorable as might reasonably have been obtained at such time from an
         unaffiliated party or (B) transactions with joint ventures or
         Unrestricted Subsidiaries for the purchase or sale of chemicals,
         equipment and services entered into in the ordinary course of business
         and in a manner consistent with past practice;

                  (xii) any transaction effected as part of a Qualified
         Receivables Financing; and

                  (xiii) the issuance of Equity Interests (other than
         Disqualified Stock) of the Company or Holdings to any Permitted Holder
         or to any director, officer, employee or consultant of the Company or
         Holdings or any direct or indirect parent company of the Company or
         Holdings.

         SECTION 4.08. Change of Control. (a) Upon a Change of Control, each
Holder shall have the right to require the Company to repurchase all or any part
of such

                                      -66-

Holder's Securities at a purchase price in cash equal to 101% of the principal
amount thereof, plus accrued and unpaid interest, if any, to the date of
repurchase (subject to the right of the Holders of record on the relevant record
date to receive interest due on the relevant interest payment date), in
accordance with the terms contemplated in this Section 4.08; provided, however,
that notwithstanding the occurrence of a Change of Control, the Company shall
not be obligated to purchase any Securities pursuant to this Section 4.08 in the
event that it has exercised its right to redeem such Securities in accordance
with Article 3 of this Indenture. In the event that at the time of such Change
of Control the terms of the Bank Indebtedness restrict or prohibit the
repurchase of Securities pursuant to this Section 4.08, then prior to the
mailing of the notice to the Holders provided for in Section 4.08(b) but in any
event within 30 days following any Change of Control, the Company shall (i)
repay in full all Bank Indebtedness, or (ii) obtain the requisite consent, if
required, under the agreements governing the Bank Indebtedness to permit the
repurchase of the Securities as provided for in Section 4.08(b).

         (b) Within 30 days following any Change of Control, except to the
extent that the Company has exercised its right to redeem the Securities in
accordance with Article 3 of this Indenture, the Company shall mail a notice (a
"Change of Control Offer") to each Holder with a copy to the Trustee and, so
long as the Securities are listed on the Luxembourg Stock Exchange, publish such
notice in a Luxembourg newspaper of general circulation, stating:

                  (i) that a Change of Control has occurred and that such Holder
         has the right to require the Company to purchase all or a portion of
         such Holder's Securities at a purchase price in cash equal to 101% of
         the principal amount thereof, plus accrued and unpaid interest to the
         date of purchase (subject to the right of the Holders of record on the
         relevant record date to receive interest on the relevant interest
         payment date);

                  (ii) the circumstances and relevant facts and financial
         information regarding such Change of Control;

                  (iii) the repurchase date (which shall be no earlier than 30
         days nor later than 60 days from the date such notice is mailed); and

                  (iv) the instructions determined by the Company, consistent
         with this Section, that a Holder must follow in order to have its
         Securities purchased.

         (c) Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
at the address specified in the notice at least three Business Days prior to the
purchase date. The Holders shall be entitled to withdraw their election if the
Trustee or the Company receives not later than one Business Day prior to the
purchase date a telegram, telex, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of the Security which was delivered
for purchase by the Holder and a statement that such Holder is withdrawing his
election to have such Security purchased. Holders whose Securities are

                                      -67-

purchased only in part shall be issued new Securities equal in principal amount
to the unpurchased portion of the Securities surrendered.

         (d) On the purchase date, all Securities purchased by the Company under
this Section shall be delivered to the Trustee for cancellation, and the Company
shall pay the purchase price plus accrued and unpaid interest to the Holders
entitled thereto.

         (e) Notwithstanding the foregoing provisions of this Section, the
Company shall not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in Section
4.08(b) applicable to a Change of Control Offer made by the Company and
purchases all Securities validly tendered and not withdrawn under such Change of
Control Offer.

         (f) At the time the Company delivers Securities to the Trustee which
are to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
pursuant to and in accordance with the terms of this Section 4.08. A Security
shall be deemed to have been accepted for purchase at the time the Trustee,
directly or through an agent, mails or delivers payment therefor to the
surrendering Holder.

         (g) Prior to any Change of Control Offer, the Company shall deliver to
the Trustee an Officers' Certificate stating that all conditions precedent
contained herein to the right of the Company to make such offer have been
complied with.

         (h) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue thereof.

         SECTION 4.09. Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with Section 314(a)(4) of
the TIA.

         SECTION 4.10. Further Instruments and Acts. Upon request of the
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

                                      -68-

         SECTION 4.11. Future Guarantors. Holdings shall cause each Restricted
Subsidiary that is a Domestic Subsidiary (unless such Subsidiary is a
Receivables Subsidiary) that:

                  (a) guarantees any Indebtedness of Holdings or any of its
         Restricted Subsidiaries; or

                  (b) Incurs any Indebtedness or issues any shares of
         Disqualified Stock permitted to be Incurred or issued pursuant to
         clause (i) or (xii) of Section 4.03(b) or not permitted to be Incurred
         by such Section

to execute and deliver to the Trustee a supplemental indenture substantially in
the form of Exhibit F pursuant to which such Subsidiary shall guarantee payment
of the Securities.

         SECTION 4.12. Liens. (a) Holdings shall not, and shall not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, Incur or
suffer to exist any Lien on any asset or property of Holdings or such Restricted
Subsidiary of Holdings, or any income or profits therefrom, or assign or convey
any right to receive income therefrom, that secures any obligations of Holdings
or any of its Restricted Subsidiaries unless the Securities are equally and
ratably secured with (or on a senior basis to, in the case of obligations
subordinated in right of payment to the Securities) the obligations so secured
or until such time as such obligations are no longer secured by a Lien. The
preceding sentence shall not require Holdings or any Restricted Subsidiary of
Holdings to secure the Securities if the Lien consists of a Permitted Lien.

         (b) No Guarantor shall directly or indirectly create, Incur or suffer
to exist any Lien on any asset or property of such Guarantor or any income or
profits therefrom, or assign or convey any right to receive income therefrom,
that secures any obligation of such Guarantor unless the Senior Guarantee of
such Guarantor is equally and ratably secured with (or on a senior basis to, in
the case of obligations subordinated in right of payment to such Guarantor's
Senior Guarantee) the obligations so secured or until such time as such
obligations are no longer secured by a Lien. The preceding sentence shall not
require any Guarantor to secure its Senior Guarantee if the Lien consists of a
Permitted Lien.

         SECTION 4.13. Maintenance of Office or Agency.

         (a) The Company shall maintain in the Borough of Manhattan, the City of
New York, in London, England and, so long as the Euro Securities are listed on
the Luxembourg Stock Exchange and the rules of such stock exchange so require,
in Luxembourg, an office or agency (which may be an office of the Trustee or an
affiliate of the Trustee or Registrar) where Securities may be surrendered for
registration of transfer or for exchange and where notices and demands to or
upon the Company in respect of the Securities and this Indenture may be served.
The Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and

                                      -69-

demands may be made or served at the corporate trust office of the Trustee as
set forth in Section 11.02.

         (b) The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York, in London, England and, so long as
the Euro Securities are listed on the Luxembourg Stock Exchange and the rules of
such stock exchange so require, in Luxembourg for such purposes. The Company
shall give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency.

         (c) The Company hereby designates the corporate trust office of the
Trustee or its Agent, in the Borough of Manhattan, The City of New York, and in
London, England and the office of the Luxembourg Paying Agent in Luxembourg, in
each case as such office or agency of the Company in accordance with Section
2.04.

                                SUCCESSOR COMPANY

         SECTION 5.01. When Company May Merge or Transfer Assets. (a) The
Company shall not consolidate or merge with or into or wind up into (whether or
not the Company is the surviving corporation), or sell, assign, transfer, lease,
convey or otherwise dispose of all or substantially all of its properties or
assets in one or more related transactions to, any Person unless:

                  (i) the Company is the surviving corporation or the Person
         formed by or surviving any such consolidation or merger (if other than
         the Company) or to which such sale, assignment, transfer, lease,
         conveyance or other disposition shall have been made is a corporation,
         partnership or limited liability company organized or existing under
         the laws of the United States, any state thereof, the District of
         Columbia, or any territory thereof (the Company or such Person, as the
         case may be, being herein called the "Successor Company");

                  (ii) the Successor Company (if other than the Company)
         expressly assumes all the obligations of the Company under this
         Indenture and the Securities pursuant to supplemental indentures or
         other documents or instruments in form reasonably satisfactory to the
         Trustee;

                  (iii) immediately after giving effect to such transaction (and
         treating any Indebtedness which becomes an obligation of the Successor
         Company or any of its Restricted Subsidiaries as a result of such
         transaction as having been Incurred by the Successor Company or such
         Restricted Subsidiary at the time of such transaction) no Default or
         Event of Default shall have occurred and be continuing;

                                      -70-

                  (iv) immediately after giving pro forma effect to such
         transaction, as if such transaction had occurred at the beginning of
         the applicable four-quarter period, either

                           (A) the Successor Company would be permitted to Incur
                  at least $1.00 of additional Indebtedness pursuant to the
                  Fixed Charge Coverage Ratio test set forth in Section 4.03(a);
                  or

                           (B) the Fixed Charge Coverage Ratio for the Successor
                  Company and its Restricted Subsidiaries would be greater than
                  such ratio for Holdings and its Restricted Subsidiaries
                  immediately prior to such transaction;

                  (v) each Guarantor, unless it is the other party to the
         transactions described above, shall have by supplemental indenture
         confirmed that its Senior Guarantee shall apply to such Person's
         obligations under this Indenture and the Securities; and

                  (vi) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger or transfer and such supplemental indentures (if
         any) comply with this Indenture.

         The Successor Company shall succeed to, and be substituted for, the
Company under this Indenture and the Securities. Notwithstanding the foregoing
clauses (iii) and (iv) of this Section 5.01, (a) any Restricted Subsidiary may
consolidate with, merge into or transfer all or part of its properties and
assets to the Company or to another Restricted Subsidiary, and (b) the Company
may merge with an Affiliate incorporated solely for the purpose of
reincorporating the Company in another state of the United States so long as the
amount of Indebtedness of the Company and its Restricted Subsidiaries is not
increased thereby.

         (b) Subject to the provisions of Section 10.02(b) (which govern the
release of a Senior Guarantee upon the sale or disposition of a Restricted
Subsidiary of Holdings that is a Guarantor), each Guarantor shall not, and the
Company shall not permit any Guarantor to, consolidate or merge with or into or
wind up into (whether or not such Guarantor is the surviving corporation), or
sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its properties or assets in one or more related
transactions to, any Person (other than any such sale, assignment, transfer,
lease, conveyance or disposition in connection with the Transactions described
in the Offering Memorandum) unless:

                  (i) such Guarantor is the surviving corporation or the Person
         formed by or surviving any such consolidation or merger (if other than
         such Guarantor) or to which such sale, assignment, transfer, lease,
         conveyance or other disposition shall have been made is a corporation,
         partnership or limited liability company organized or existing under
         the laws of the United States, any state thereof, the District of
         Columbia, or any territory thereof (such Guarantor or such Person, as
         the case may be, being herein called the "Successor Guarantor");

                  (ii) the Successor Guarantor (if other than such Guarantor)
         expressly assumes all the obligations of such Guarantor under this
         Indenture and such

                                      -71-

         Guarantors' Senior Guarantee pursuant to a supplemental indenture or
         other documents or instruments in form reasonably satisfactory to the
         Trustee;

                  (iii) immediately after giving effect to such transaction (and
         treating any Indebtedness which becomes an obligation of the Successor
         Guarantor or any of its Subsidiaries as a result of such transaction as
         having been Incurred by the Successor Guarantor or such Subsidiary at
         the time of such transaction) no Default or Event of Default shall have
         occurred and be continuing; and

                  (iv) the Successor Guarantor (if other than such Guarantor)
         shall have delivered or caused to be delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that such
         consolidation, merger or transfer and such supplemental indenture (if
         any) comply with this Indenture.

                  The Successor Guarantor shall succeed to, and be substituted
for, such Guarantor under this Indenture and such Guarantor's Senior Guarantee.
Notwithstanding the foregoing, (1) a Guarantor may merge with an Affiliate
incorporated solely for the purpose of reincorporating such Guarantor in another
state of the United States, so long as the amount of Indebtedness of the
Guarantor is not increased thereby, (2) Holdings may merge with the Company and
(3) a Guarantor may merge with another Guarantor or the Company.

                  Notwithstanding the foregoing, any Guarantor (other than
Holdings) may consolidate or merge with or into or wind up into, or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of its properties or assets (collectively, a "Transfer") to, any Restricted
Subsidiary of the Company that is not a Guarantor; provided that at the time of
each such Transfer the aggregate amount of all such Transfers since the Issue
Date shall not exceed 5% of the consolidated assets of the Company and the
Guarantors as shown on the most recent available balance sheet of Holdings and
the Restricted Subsidiaries after giving effect to each such Transfer and
including all Transfers occurring from and after the Issue Date (excluding
Transfers in connection with the Transactions described in the Offering
Memorandum).

                                   ARTICLE 6

                              DEFAULTS AND REMEDIES

         SECTION 6.01. Events of Default. An "Event of Default" occurs if:

                  (a) the Company defaults in any payment of interest on any
         Security when the same becomes due and payable, and such default
         continues for a period of 30 days,

                  (b) the Company defaults in the payment of principal or
         premium, if any, of any Security when due at its Stated Maturity, upon
         optional redemption, upon required repurchase, upon declaration or
         otherwise,

                  (c) the Company fails to comply with its obligations under
         Section 5.01,

                                      -72-

                  (d) Holdings or any of its Restricted Subsidiaries fails to
         comply with any of its obligations under the covenants set forth in
         Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.11 and 4.12 (in
         each case, other than a failure to purchase Securities when required
         under Section 4.06 or 4.08) and such failure continues for 30 days
         after the notice specified below,

                  (e) Holdings or any of its Restricted Subsidiaries fails to
         comply with any of its agreements in the Securities or this Indenture
         (other than those referred to in (a), (b), (c), or (d) above) and such
         failure continues for 60 days after the notice specified below,

                  (f) Holdings, the Company or any Significant Subsidiary fails
         to pay any Indebtedness (other than Indebtedness owing to Holdings or a
         Restricted Subsidiary of Holdings) within any applicable grace period
         after final maturity or the acceleration of any such Indebtedness by
         the holders thereof because of a default, in each case, if the total
         amount of such Indebtedness unpaid or accelerated exceeds $35 million
         or its foreign currency equivalent,

                  (g) Holdings, the Company or any Significant Subsidiary of
         Holdings pursuant to or within the meaning of any Bankruptcy Law:

                           (i) commences a voluntary case;

                           (ii) consents to the entry of an order for relief
                  against it in an involuntary case;

                           (iii) consents to the appointment of a Custodian of
                  it or for any substantial part of its property; or

                           (iv) makes a general assignment for the benefit of
                  its creditors or takes any comparable action under any foreign
                  laws relating to insolvency,

                  (h) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that:

                           (i) is for relief against Holdings, the Company or
                  any Significant Subsidiary of Holdings in an involuntary case;

                           (ii) appoints a Custodian of Holdings, the Company or
                  any Significant Subsidiary of Holdings or for any substantial
                  part of its property; or

                           (iii) orders the winding up or liquidation of
                  Holdings, the Company or any Significant Subsidiary of
                  Holdings;

         or any similar relief is granted under any foreign laws and the order
         or decree remains unstayed and in effect for 60 days,

                                      -73-

                  (i) Holdings, the Company or any Significant Subsidiary fails
         to pay final judgments aggregating in excess of $35 million or its
         foreign currency equivalent (net of any amounts which are covered by
         enforceable insurance policies issued by solvent carriers), which
         judgments are not discharged, waived or stayed for a period of 60 days
         following the entry thereof, or

                  (j) the Senior Guarantee of Holdings or any Senior Guarantee
         of a Significant Subsidiary ceases to be in full force and effect
         (except as contemplated by the terms thereof) or any Guarantor denies
         or disaffirms its obligations under this Indenture or any Senior
         Guarantee and such Default continues for 10 days after the notice
         specified below.

         The foregoing shall constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

         The term "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

         A Default under clause (d), (e) or (j) above shall not constitute an
Event of Default until the Trustee notifies the Company or the Holders of at
least 25% in principal amount of the outstanding Securities notify the Company
and the Trustee of the Default and the Company does not cure such Default within
the time specified in clauses (d), (e) or (j) above after receipt of such
notice. Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default". The Company shall deliver to
the Trustee, within five (5) Business Days after the occurrence thereof, written
notice in the form of an Officers' Certificate of any event which is, or with
the giving of notice or the lapse of time or both would become, an Event of
Default, its status and what action the Company is taking or proposes to take
with respect thereto.

         SECTION 6.02. Acceleration. If an Event of Default (other than an Event
of Default specified in Section 6.01(g) or (h) with respect to Holdings or the
Company) occurs and is continuing, the Trustee by notice to the Company or the
Holders of at least 25% in principal amount of outstanding Securities by notice
to the Company and the Trustee, may declare the principal of, premium, if any,
and accrued but unpaid interest on all the Securities to be due and payable.
Upon such a declaration, such principal and interest shall be due and payable
immediately. If an Event of Default specified in Section 6.01(g) or (h) with
respect to Holdings or the Company occurs, the principal of, premium, if any,
and interest on all the Securities shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holders. The Holders of a majority in principal amount of the Securities
by notice to the Trustee may rescind an acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing
Events of Default have been cured or waived except nonpayment of principal or

                                      -74-

interest that has become due solely because of acceleration. No such rescission
shall affect any subsequent Default or impair any right consequent thereto.

         In the event of any Event of Default specified in Section 6.01(f), such
Event of Default and all consequences thereof (excluding, however, any resulting
payment default) shall be annulled, waived and rescinded, automatically and
without any action by the Trustee or the Holders of the Securities, if within 20
days after such Event of Default arose the Company delivers an Officers'
Certificate to the Trustee stating that (x) the Indebtedness or guarantee that
is the basis for such Event of Default has been discharged or (y) the holders
thereof have rescinded or waived the acceleration, notice or action (as the case
may be) giving rise to such Event of Default or (z) the default that is the
basis for such Event of Default has been cured, it being understood that in no
event shall an acceleration of the principal amount of the Securities as
described above be annulled, waived or rescinded upon the happening of any such
events.

         SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy at law or in equity to
collect the payment of principal of or interest on the Securities or to enforce
the performance of any provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative.

         SECTION 6.04. Waiver of Past Defaults. Provided the Securities are not
then due and payable by reason of a declaration of acceleration, the Holders of
a majority in principal amount of the Securities by notice to the Trustee may
waive an existing Default and its consequences except (a) a Default in the
payment of the principal of or interest on a Security, (b) a Default arising
from the failure to redeem or purchase any Security when required pursuant to
the terms of this Indenture or (c) a Default in respect of a provision that
under Section 9.02 cannot be amended without the consent of each Holder
affected. When a Default is waived, it is deemed cured and the Company, the
Trustee and the Holders will be restored to their former positions and rights
under this Indenture, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

         SECTION 6.05. Control by Majority. The Holders of a majority in
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of any other Holder or that would involve the Trustee in personal
liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action

                                      -75-

under this Indenture, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

         SECTION 6.06. Limitation on Suits. (a) Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no Holder
may pursue any remedy with respect to this Indenture or the Securities unless:

                  (i) the Holder gives to the Trustee written notice stating
         that an Event of Default is continuing;

                  (ii) the Holders of at least 25% in principal amount of the
         Securities make a written request to the Trustee to pursue the remedy;

                  (iii) such Holder or Holders offer to the Trustee reasonable
         security or indemnity satisfactory to it against any loss, liability or
         expense;

                  (iv) the Trustee does not comply with the request within 60
         days after receipt of the request and the offer of security or
         indemnity; and

                  (v) the Holders of a majority in principal amount of the
         Securities do not give the Trustee a direction inconsistent with the
         request during such 60-day period.

         (b) A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over another Holder.

         SECTION 6.07. Rights of the Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and interest on the Securities held by such Holder, on
or after the respective due dates expressed or provided for in the Securities,
or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder.

         SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or any other obligor on the Securities for the whole amount then due and
owing (together with interest on overdue principal and (to the extent lawful) on
any unpaid interest at the rate provided for in the Securities) and the amounts
provided for in Section 7.07.

         SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for
reasonable compensation, expenses disbursements and advances of the Trustee
(including counsel, accountants, experts or such other professionals as the
Trustee deems necessary, advisable or appropriate)) and the Holders allowed in
any judicial proceedings relative to the Company or any Guarantor, their
creditors or their property, shall be entitled to participate as a member,
voting or otherwise, of any official committee of creditors appointed in such
matters and, unless prohibited by law or

                                      -76-

applicable regulations, may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other Person performing similar functions, and any
Custodian in any such judicial proceeding is hereby authorized by each Holder to
make payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 7.07.

         SECTION 6.10. Priorities. If the Trustee collects any money or property
pursuant to this Article 6, it shall pay out the money or property in the
following order:

                  FIRST: to the Trustee for amounts due under Section 7.07;

                  SECOND: to Holders for amounts due and unpaid on the
         Securities for principal, premium, if any, and interest, ratably,
         without preference or priority of any kind, according to the amounts
         due and payable on the Securities for principal and interest,
         respectively; and

                  THIRD: to the Company or, to the extent the Trustee collects
         any amount for any Subsidiary Guarantor, to such Subsidiary Guarantor.

         The Trustee may fix a record date and payment date for any payment to
the Holders pursuant to this Section. At least 15 days before such record date,
the Trustee shall mail to each Holder and the Company a notice that states the
record date, the payment date and amount to be paid.

         SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in principal amount of the Securities.

         SECTION 6.12. Waiver of Stay or Extension Laws. Neither the Company nor
any Guarantor (to the extent it may lawfully do so) shall at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Company and each Guarantor (to the extent that it may
lawfully do so) hereby expressly waive all benefit or advantage of any such law,
and shall not hinder, delay or impede the execution of any power herein granted
to the Trustee, but shall suffer and permit the execution of every such power as
though no such law had been enacted.

                                      -77-

                                   ARTICLE 7

                                     TRUSTEE

         SECTION 7.01. Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the circumstances
in the conduct of such person's own affairs.

         (b) Except during the continuance of an Event of Default:

                  (i) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, in the case of certificates or opinions
         required by any provision hereof to be provided to it, the Trustee
         shall examine the certificates and opinions to determine whether or not
         they conform to the requirements of this Indenture.

         (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                  (i) this paragraph does not limit the effect of paragraph (b)
         of this Section;

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Trust Officer unless it is proved that the
         Trustee was negligent in ascertaining the pertinent facts;

                  (iii) the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05; and

                  (iv) no provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur financial liability
         in the performance of any of its duties hereunder or in the exercise of
         any of its rights or powers.

         (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

         (e) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company.

                                      -78-

         (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

         (g) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

         SECTION 7.02. Rights of Trustee. (a) The Trustee may conclusively rely
on any document believed by it to be genuine and to have been signed or
presented by the proper person. The Trustee need not investigate any fact or
matter stated in the document.

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on the
Officers' Certificate or Opinion of Counsel.

         (c) The Trustee may act through agents and shall not be responsible for
the misconduct or negligence of any agent appointed with due care.

         (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith which it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute
willful misconduct or negligence.

         (e) The Trustee may consult with counsel of its own selection and the
advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Securities shall be full and complete authorization and
protection from liability in respect of any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

         (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, debenture,
note or other paper or document unless requested in writing to do so by the
Holders of not less than a majority in principal amount of the Securities at the
time outstanding, but the Trustee, in its discretion, may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if
the Trustee shall determine to make such further inquiry or investigation, it
shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney, at the expense of the Company and shall
incur no liability of any kind by reason of such inquiry or investigation.

         (g) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders pursuant to this Indenture, unless such Holders shall have
offered to the Trustee security or indemnity satisfactory to the Trustee against
the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction.

                                      -79-

         (h) The rights, privileges, protections, immunities and benefits given
to the Trustee, including its right to be indemnified, are extended to, and
shall be enforceable by, the Trustee in each of its capacities hereunder, and
each agent, custodian and other Person employed to act hereunder.

         SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent or Registrar may do the
same with like rights. However, the Trustee must comply with Sections 7.10 and
7.11.

         SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, any Senior Guarantee or the Securities, it shall not be
accountable for the Company's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Company or any Guarantor in
this Indenture or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication. The Trustee shall not be charged with knowledge of any Default
or Event of Default under Sections 6.01(c), (d), (e), (f), (i) or (j) or of the
identity of any Significant Subsidiary unless either (a) a Trust Officer shall
have actual knowledge thereof or (b) the Trustee shall have received notice
thereof in accordance with Section 11.02 hereof from the Company, any Guarantor
or any Holder.

         SECTION 7.05. Notice of Defaults. If a Default occurs and is continuing
and if it is actually known to the Trustee, the Trustee shall mail to each
Holder notice of the Default within the earlier of 90 days after it occurs or 30
days after it is actually known to a Trust Officer or written notice of it is
received by the Trustee. Except in the case of a Default in the payment of
principal of, premium (if any) or interest on any Security, the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is in the interests of the Holders.

         SECTION 7.06. Reports by Trustee to the Holders. As promptly as
practicable after each September 30 beginning with the September 30 following
the date of this Indenture, and in any event prior to September 30 in each year,
the Trustee shall mail to each Holder a brief report dated as of such September
30 that complies with Section 313(a) of the TIA if and to the extent required
thereby. The Trustee shall also comply with Section 313(b) of the TIA.

         A copy of each report at the time of its mailing to the Holders shall
be filed with the SEC and each stock exchange (if any) on which the Securities
are listed. The Company agrees to notify promptly the Trustee whenever the
Securities become listed on any stock exchange and of any delisting thereof.

         SECTION 7.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.

                                      -80-

The Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the
reasonable compensation and expenses, disbursements and advances of the
Trustee's agents, counsel, accountants and experts. The Company and each
Guarantor, jointly and severally shall indemnify the Trustee against any and all
loss, liability, claim, damage or expense (including reasonable attorneys' fees
and expenses) incurred by or in connection with the acceptance or administration
of this trust and the performance of its duties hereunder, including the costs
and expenses of enforcing this Indenture or Guarantee against the Company or a
Guarantor (including this Section 7.07) and defending itself against or
investigating any claim (whether asserted by the Company, any Guarantor, any
Holder or any other Person). The Trustee shall notify the Company of any claim
for which it may seek indemnity promptly upon obtaining actual knowledge
thereof; provided, however, that any failure so to notify the Company shall not
relieve the Company or any Guarantor of its indemnity obligations hereunder. The
Company shall defend the claim and the indemnified party shall provide
reasonable cooperation at the Company's expense in the defense. Such indemnified
parties may have separate counsel and the Company and the Guarantors, as
applicable shall pay the fees and expenses of such counsel; provided, however,
that the Company shall not be required to pay such fees and expenses if it
assumes such indemnified parties' defense and, in such indemnified parties'
reasonable judgment, there is no conflict of interest between the Company and
the Guarantors, as applicable, and such parties in connection with such defense.
The Company need not reimburse any expense or indemnify against any loss,
liability or expense incurred by an indemnified party through such party's own
willful misconduct, negligence or bad faith.

         To secure the Company's and the Guarantors' payment obligations in this
Section, the Trustee shall have a Lien prior to the Securities on all money or
property held or collected by the Trustee other than money or property held in
trust to pay principal of and interest on particular Securities.

         The Company's and the Guarantors' payment obligations pursuant to this
Section shall survive the satisfaction or discharge of this Indenture, any
rejection or termination of this Indenture under any bankruptcy law or the
resignation or removal of the Trustee. Without prejudice to any other rights
available to the Trustee under applicable law, when the Trustee incurs expenses
after the occurrence of a Default specified in Section 6.01(g) or (h) with
respect to Holdings or the Company, the expenses are intended to constitute
expenses of administration under the Bankruptcy Law.

         SECTION 7.08. Replacement of Trustee. (a) The Trustee may resign at any
time by so notifying the ompany. The Holders of a majority in principal amount
of the Securities may remove the Trustee by so notifying the Trustee and may
appoint a successor Trustee. The Company shall remove the Trustee if:

                  (i) the Trustee fails to comply with Section 7.10;

                  (ii) the Trustee is adjudged bankrupt or insolvent;

                                      -81-

                  (iii) a receiver or other public officer takes charge of the
         Trustee or its property; or

                  (iv) the Trustee otherwise becomes incapable of acting.

         (b) If the Trustee resigns, is removed by the Company or by the Holders
of a majority in principal amount of the Securities and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

         (c) A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to the Holders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the Lien
provided for in Section 7.07.

         (d) If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee or the Holders
of 10% in principal amount of the Securities may petition at the expense of the
Company any court of competent jurisdiction for the appointment of a successor
Trustee.

         (e) If the Trustee fails to comply with Section 7.10, unless the
Trustee's duty to resign is stayed as provided in Section 310(b) of the TIA, any
Holder who has been a bona fide holder of a Security for at least six months may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

         (f) Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

         SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

         In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
successor to the Trustee may authenticate such Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in
all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the
Trustee shall have.

                                      -82-

         SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of Section 310(a) of the TIA. The Trustee shall
have a combined capital and surplus of at least $100,000,000 as set forth in its
most recent published annual report of condition. The Trustee shall comply with
Section 310(b) of the TIA, subject to its right to apply for a stay of its duty
to resign under the penultimate paragraph of Section 310(b) of the TIA;
provided, however, that there shall be excluded from the operation of Section
310(b)(1) of the TIA any series of securities issued under this Indenture and
any indenture or indentures under which other securities or certificates of
interest or participation in other securities of the Company are outstanding if
the requirements for such exclusion set forth in Section 310(b)(1) of the TIA
are met.

         SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with Section 311(a) of the TIA, excluding any creditor
relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or
been removed shall be subject to Section 311(a) of the TIA to the extent
indicated.

                                   ARTICLE 8

                       DISCHARGE OF INDENTURE; DEFEASANCE

         SECTION 8.01. Discharge of Liability on Securities; Defeasance. This
Indenture shall be discharged and shall cease to be of further effect (except as
to surviving rights of registration of transfer or exchange of Securities, as
expressly provided for in this Indenture) as to all outstanding Securities:

                  (a) when (i) all the Securities theretofore authenticated and
         delivered (other than Securities pursuant to Section 2.08 which have
         been replaced or paid and Securities for whose payment money has
         theretofore been deposited in trust or segregated and held in trust by
         the Company and thereafter repaid to the Company or discharged from
         such trust) have been delivered to the Trustee for cancellation or (ii)
         all of the Securities (a) have become due and payable, (b) will become
         due and payable at their stated maturity within one year or (c) if
         redeemable at the option of the Company, are to be called for
         redemption within one year under arrangements satisfactory to the
         Trustee for the giving of notice of redemption by the Trustee in the
         name, and at the expense, of the Company, and the Company has
         irrevocably deposited or caused to be deposited with the Trustee funds
         (i) in respect of the Dollar Securities, cash in U.S. Dollars, U.S.
         Government Obligations or a combination thereof or (ii) in respect of
         the Euro Securities, cash in Euros, EU Government Obligations or a
         combination thereof in each case, in an amount sufficient in the
         written opinion of a firm of independent public accountants delivered
         to the Trustee (which delivery shall only be required if Government
         Obligations have been so deposited) to pay and discharge the entire
         Indebtedness on the Securities not theretofore delivered to the Trustee
         for cancellation, for principal of, premium, if any, and interest on
         the Securities to the date of deposit together with irrevocable
         instructions from the Company directing the Trustee to apply such funds
         to the payment thereof at maturity or redemption, as the case may be;

                                      -83-

                  (b) the Company and/or the Guarantors have paid all other sums
         payable under this Indenture; and

                  (c) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel stating that all conditions
         precedent under this Indenture relating to the satisfaction and
         discharge of this Indenture have been complied with.

         Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (i) all of its obligations under the Dollar Securities and/or the Euro
Securities and this Indenture (with respect to such Securities) ("legal
defeasance option") or (ii) its obligations under Sections 4.02, 4.03, 4.04,
4.05, 4.06, 4.07, 4.08, 4.11 and 4.12 and the operation of Section 5.01 and
Sections 6.01(c), 6.01(d), 6.01(f), 6.01(g) (with respect to Significant
Subsidiaries of the Company only), 6.01(h) (with respect to Significant
Subsidiaries of the Company only), 6.01(i) and 6.01(j) ("covenant defeasance
option"). The Company may exercise its legal defeasance option notwithstanding
its prior exercise of its covenant defeasance option. In the event that the
Company terminates all of its obligations under the Dollar Securities and/or the
Euro Securities and this Indenture (with respect to such Securities) by
exercising its legal defeasance option or its covenant defeasance option, the
obligations of each Guarantor under its Senior Guarantee of such Securities
shall be terminated simultaneously with the termination of such obligations.

         If the Company exercises its legal defeasance option, payment of the
Securities so defeased may not be accelerated because of an Event of Default. If
the Company exercises its covenant defeasance option, payment of the Securities
so defeased may not be accelerated because of an Event of Default specified in
Section 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (with respect to Significant
Subsidiaries of the Company only), 6.01(h) (with respect to Significant
Subsidiaries of the Company only), 6.01(i) or 6.01(j) or because of the failure
of the Company to comply with Section 5.01.

         Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

         (d) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.05 and 8.06 shall
survive such satisfaction and discharge.

         SECTION 8.02. Conditions to Defeasance. (a) The Company may exercise
its legal defeasance option or its covenant defeasance option only if:

                  (i) the Company irrevocably deposits in trust with the Trustee
         (x) in respect of the Dollar Securities, cash in U.S. Dollars, U.S.
         Government Obligations or a combination thereof or (y) in respect of
         the Euro Securities, cash in Euros, EU Government Obligations or a
         combination thereof in each case, in an amount sufficient or Government
         Obligations, the principal of and the interest on which will

                                      -84-

         be sufficient, or a combination thereof sufficient, to pay the
         principal of, and premium (if any) and interest on the applicable
         Securities when due at maturity or redemption, as the case may be,
         including interest thereon to maturity or such redemption date;

                  (ii) the Company delivers to the Trustee a certificate from a
         nationally recognized firm of independent accountants expressing their
         opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obligations plus
         any deposited money without investment will provide cash at such times
         and in such amounts as will be sufficient to pay principal, premium, if
         any, and interest when due on all the Securities to maturity or
         redemption, as the case may be;

                  (iii) 123 days pass after the deposit is made and during the
         123-day period no Default specified in Section 6.01(g) or (h) with
         respect to the Company occurs which is continuing at the end of the
         period;

                  (iv) the deposit does not constitute a default under any other
         agreement binding on the Company;

                  (v) the Company delivers to the Trustee an Opinion of Counsel
         to the effect that the trust resulting from the deposit does not
         constitute, or is qualified as, a regulated investment company under
         the Investment Company Act of 1940;

                  (vi) in the case of the legal defeasance option, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (1) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (2) since the date of this
         Indenture there has been a change in the applicable Federal income tax
         law, in either case to the effect that, and based thereon such Opinion
         of Counsel shall confirm that, the Holders will not recognize income,
         gain or loss for Federal income tax purposes as a result of such
         deposit and defeasance and will be subject to Federal income tax on the
         same amounts, in the same manner and at the same times as would have
         been the case if such deposit and defeasance had not occurred;

                  (vii) in the case of the covenant defeasance option, the
         Company shall have delivered to the Trustee an Opinion of Counsel to
         the effect that the Holders will not recognize income, gain or loss for
         Federal income tax purposes as a result of such deposit and defeasance
         and will be subject to Federal income tax on the same amounts, in the
         same manner and at the same times as would have been the case if such
         deposit and defeasance had not occurred; and

                  (viii)   the Company delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance and discharge of the Securities to be so
         defeased and discharged as contemplated by this Article 8 have been
         complied with.

                                      -85-

         (b) Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of such Securities at a future
date in accordance with Article 3.

         SECTION 8.03. Application of Trust Money. The Trustee shall hold in
trust money or Government Obligations (including proceeds thereof) deposited
with it pursuant to this Article 8. It shall apply the deposited money and the
money from Government Obligations through each Paying Agent and in accordance
with this Indenture to the payment of principal of and interest on the
Securities so discharged or defeased.

         SECTION 8.04. Repayment to Company. Each of the Trustee and each Paying
Agent shall promptly turn over to the Company upon request any money or
Government Obligations held by it as provided in this Article which, in the
written opinion of nationally recognized firm of independent public accountants
delivered to the Trustee (which delivery shall only be required if Government
Obligations have been so deposited), are in excess of the amount thereof which
would then be required to be deposited to effect an equivalent discharge or
defeasance in accordance with this Article.

         Subject to any applicable abandoned property law, the Trustee and each
Paying Agent shall pay to the Company upon written request any money held by
them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Holders entitled to the money must look to the Company
for payment as general creditors, and the Trustee and each Paying Agent shall
have no further liability with respect to such monies.

         SECTION 8.05. Indemnity for Government Obligations. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited Government Obligations or the principal and
interest received on such Government Obligations.

         SECTION 8.06. Reinstatement. If the Trustee or any Paying Agent is
unable to apply any money or Government Obligations in accordance with this
Article 8 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities so discharged or defeased shall be revived and
reinstated as though no deposit had occurred pursuant to this Article 8 until
such time as the Trustee or any Paying Agent is permitted to apply all such
money or Government Obligations in accordance with this Article 8; provided,
however, that, if the Company has made any payment of principal of or interest
on, any such Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money or Government Obligations held by the
Trustee or any Paying Agent.

                                      -86-

                                   ARTICLE 9

                             AMENDMENTS AND WAIVERS

         SECTION 9.01. Without Consent of the Holders. The Company and the
Trustee may amend this Indenture or the Securities without notice to or consent
of any Holder:

                  (i) to cure any ambiguity, omission, defect or inconsistency;

                  (ii) to comply with Article 5;

                  (iii) to provide for uncertificated Securities in addition to
         or in place of certificated Securities; provided, however, that the
         uncertificated Securities are issued in registered form for purposes of
         Section 163(f) of the Code or in a manner such that the uncertificated
         Securities are described in Section 163(f)(2)(B) of the Code;

                  (iv) to add additional Senior Guarantees with respect to the
         Securities or to secure the Securities;

                  (v) to add to the covenants of the Company or Holdings for the
         benefit of the Holders or to surrender any right or power herein
         conferred upon the Company or Holdings;

                  (vi) to comply with any requirement of the SEC in connection
         with qualifying or maintaining the qualification of, this Indenture
         under the TIA;

                  (vii) to make any change that does not adversely affect the
         rights of any Holder; or

                  (viii) to provide for the issuance of the Exchange Securities
         or Additional Securities, which shall have terms substantially
         identical in all material respects to the Initial Securities, and which
         shall be treated, together with any outstanding Initial Securities, as
         a single issue of securities.

         After an amendment under this Section 9.01 becomes effective, the
Company shall mail to Holders a notice briefly describing such amendment. The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.01.

         SECTION 9.02. With Consent of the Holders. (a) The Company and the
Trustee may amend this Indenture or the Securities with the written consent of
the Holders of at least a majority in principal amount of the Securities then
outstanding voting as a single class (including consents obtained in connection
with a tender offer or exchange for the Securities); provided, however, that if
any amendment, waiver or other modification will only affect the Dollar
Securities or the Euro Securities, only the consent of the Holders of at least a

                                      -87-

majority in principal amount of the then outstanding Dollar Securities or Euro
Securities (and not the consent of the Holders of at least a majority of all
Securities), as the case may be, shall be required. However, without the consent
of each Holder of an outstanding Security affected, an amendment may not:

                  (i) reduce the amount of Securities whose Holders must consent
         to an amendment,

                  (ii) reduce the rate of or extend the time for payment of
         interest on any Security,

                  (iii) reduce the principal of or change the Stated Maturity of
         any Security,

                  (iv) reduce the premium payable upon the redemption of any
         Security or change the time at which any Security may be redeemed in
         accordance with Article 3,

                  (v) make any Security payable in money other than that stated
         in such Security,

                  (vi) make any change in Section 6.04 or 6.07 or the second
         sentence of this Section 9.02,

                  (vii) expressly subordinate the Securities or any Senior
         Guarantee to any other Indebtedness of the Company or any Guarantor, or

                  (viii) modify the Senior Guarantees in any manner adverse to
         the Holders.

         It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

         (b) After an amendment under this Section 9.02 becomes effective, the
Company shall mail to the Holders a notice briefly describing such amendment.
The failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section 9.02.

         SECTION 9.03. Compliance with Trust Indenture Act. From the date on
which this Indenture is qualified under the TIA, every amendment, waiver or
supplement to this Indenture or the Securities shall comply with the TIA as then
in effect.

         SECTION 9.04. Revocation and Effect of Consents and Waivers. (a) A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date on which the Trustee receives an Officers'
Certificate

                                      -88-

from the Company certifying that the requisite principal amount of Securities
have consented. After an amendment or waiver becomes effective, it shall bind
every Holder. An amendment or waiver becomes effective upon the (i) receipt by
the Company or the Trustee of consents by the Holders of the requisite principal
amount of securities, (ii) satisfaction of conditions to effectiveness as set
forth in this Indenture and any indenture supplemental hereto containing such
amendment or waiver and (iii) execution of such amendment or waiver (or
supplemental indenture) by the Company and the Trustee.

         (b) The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall be valid or effective for more than 120
days after such record date.

         SECTION 9.05. Notation on or Exchange of Securities. If an amendment,
supplement or waiver changes the terms of a Security, the Company may require
the Holder of the Security to deliver it to the Trustee. The Trustee may place
an appropriate notation on the Security regarding the changed terms and return
it to the Holder. Alternatively, if the Company or the Trustee so determines,
the Company in exchange for the Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms. Failure to make the
appropriate notation or to issue a new Security shall not affect the validity of
such amendment, supplement or waiver.

         SECTION 9.06. Trustee to Sign Amendments. The Trustee shall sign any
amendment, supplement or waiver authorized pursuant to this Article 9 if the
amendment does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. If it does, the Trustee may but need not sign it. In
signing such amendment, the Trustee shall be entitled to receive indemnity
reasonably satisfactory to it and shall be provided with, and (subject to
Section 7.01) shall be fully protected in relying upon, an Officers' Certificate
and an Opinion of Counsel stating that such amendment, supplement or waiver is
authorized or permitted by this Indenture and that such amendment, supplement or
waiver is the legal, valid and binding obligation of the Company and the
Guarantors, enforceable against them in accordance with its terms, subject to
customary exceptions, and complies with the provisions hereof (including Section
9.03).

         SECTION 9.07. Payment for Consent. Neither Holdings nor any Affiliate
of Holdings shall, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder for
or as an inducement to any consent, waiver or amendment of any of the terms or
provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                      -89-

         SECTION 9.08. Additional Voting Terms; Calculation of Principal Amount.
Except as provided in the proviso to the first sentence of Section 9.02(a), all
Securities issued under this Indenture shall vote and consent together on all
matters (as to which any of such Securities may vote) as one class and no series
of Securities will have the right to vote or consent as a separate class on any
matter. Determinations as to whether Holders of the requisite aggregate
principal amount of Securities have concurred in any direction, waiver or
consent shall be made in accordance with this Article Nine and Section 2.14.

                                   ARTICLE 10

                                SENIOR GUARANTEES

         SECTION 10.01. Senior Guarantees. (a) Each Guarantor hereby jointly and
severally, irrevocably and unconditionally guarantees, as a primary obligor and
not merely as a surety, to each Holder and to the Trustee and its successors and
assigns (i) the full and punctual payment when due, whether at Stated Maturity,
by acceleration, by redemption or otherwise, of all obligations of the Company
under this Indenture (including obligations to the Trustee) and the Securities,
whether for payment of principal of, premium, if any, or interest on in respect
of the Securities and all other monetary obligations of the Company under this
Indenture and the Securities and (ii) the full and punctual performance within
applicable grace periods of all other obligations of the Company whether for
fees, expenses, indemnification or otherwise under this Indenture and the
Securities (all the foregoing being hereinafter collectively called the
"Guaranteed Obligations"). Each Guarantor further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from each such Guarantor, and that each such Guarantor shall
remain bound under this Article 10 notwithstanding any extension or renewal of
any Guaranteed Obligation.

         (b) Each Guarantor waives presentation to, demand of payment from and
protest to the Company of any of the Guaranteed Obligations and also waives
notice of protest for nonpayment. Each Guarantor waives notice of any default
under the Securities or the Guaranteed Obligations. The obligations of each
Guarantor hereunder shall not be affected by (i) the failure of any Holder or
the Trustee to assert any claim or demand or to enforce any right or remedy
against the Company or any other Person under this Indenture, the Securities or
any other agreement or otherwise; (ii) any extension or renewal of this
Indenture, the Securities or any other agreement; (iii) any rescission, waiver,
amendment or modification of any of the terms or provisions of this Indenture,
the Securities or any other agreement; (iv) the release of any security held by
any Holder or the Trustee for the Guaranteed Obligations or any Guarantor; (v)
the failure of any Holder or Trustee to exercise any right or remedy against any
other guarantor of the Guaranteed Obligations; or (vi) any change in the
ownership of such Guarantor, except as provided in Section 10.02(b).

         (c) Each Guarantor hereby waives any right to which it may be entitled
to have its obligations hereunder divided among the Guarantors, such that such
Guarantor's obligations would be less than the full amount claimed. Each
Guarantor hereby waives any right to which it may be entitled to have the assets
of the Company first be used and depleted as payment of the Company's or such
Guarantor's obligations hereunder prior to any amounts

                                      -90-

being claimed from or paid by such Guarantor hereunder. Each Guarantor hereby
waives any right to which it may be entitled to require that the Company be sued
prior to an action being initiated against such Guarantor.

         (d) Each Guarantor further agrees that its Senior Guarantee herein
constitutes a guarantee of payment, performance and compliance when due (and not
a guarantee of collection) and waives any right to require that any resort be
had by any Holder or the Trustee to any security held for payment of the
Guaranteed Obligations.

         (e) Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06,
the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Guarantor herein shall not be discharged or
impaired or otherwise affected by the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any remedy under this Indenture, the
Securities or any other agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of
the obligations, or by any other act or thing or omission or delay to do any
other act or thing which may or might in any manner or to any extent vary the
risk of any Guarantor or would otherwise operate as a discharge of any Guarantor
as a matter of law or equity.

         (f) Each Guarantor agrees that its Senior Guarantee shall remain in
full force and effect until payment in full of all the Guaranteed Obligations.
Each Guarantor further agrees that its Senior Guarantee herein shall continue to
be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal of or interest on any Guaranteed Obligation is
rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise.

         (g) In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Guaranteed Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Guaranteed Obligation, each Guarantor hereby
promises to and shall, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (i) the unpaid principal amount of such Guaranteed Obligations,
(ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the
extent not prohibited by applicable law) and (iii) all other monetary
obligations of the Company to the Holders and the Trustee.

         (h) Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any Guaranteed Obligations
guaranteed hereby until payment in full of all Guaranteed Obligations. Each
Guarantor further agrees

                                      -91-

that, as between it, on the one hand, and the Holders and the Trustee, on the
other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may
be accelerated as provided in Article 6 for the purposes of any Senior Guarantee
herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby,
and (ii) in the event of any declaration of acceleration of such Guaranteed
Obligations as provided in Article 6, such Guaranteed Obligations (whether or
not due and payable) shall forthwith become due and payable by such Guarantor
for the purposes of this Section 10.01.

         (i) Each Guarantor also agrees to pay any and all costs and expenses
(including reasonable attorneys' fees and expenses) incurred by the Trustee or
any Holder in enforcing any rights under this Section 10.01.

         (j) Upon request of the Trustee, each Guarantor shall execute and
deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

         SECTION 10.02. Limitation on Liability. (a) Any term or provision of
this Indenture to the contrary notwithstanding, the maximum aggregate amount of
the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not
exceed the maximum amount that can be hereby guaranteed without rendering this
Indenture, as it relates to such Guarantor, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

         (b) A Senior Guarantee as to any Subsidiary Guarantor shall terminate
and be of no further force or effect and such Subsidiary Guarantor shall be
deemed to be released from all obligations under this Article 10 upon:

                  (i) the sale, disposition or other transfer (including through
         merger or consolidation) of the Capital Stock (including any sale,
         disposition or other transfer following which the applicable Subsidiary
         Guarantor is no longer a Restricted Subsidiary), or all or
         substantially all the assets, of the applicable Subsidiary Guarantor if
         such sale, disposition or other transfer is made in compliance with
         this Indenture,

                  (ii) Holdings designating such Subsidiary Guarantor to be an
         Unrestricted Subsidiary in accordance with the provisions set forth
         under Section 4.04 and the definition of "Unrestricted Subsidiary,"

                  (iii) in the case of any Restricted Subsidiary which after the
         Issue Date is required to guarantee the Securities pursuant to Section
         4.11, the release or discharge of the guarantee by such Restricted
         Subsidiary of Indebtedness of Holdings or any Restricted Subsidiary of
         Holdings or such Restricted Subsidiary or the repayment of the
         Indebtedness or Disqualified Stock, in each case, which resulted in the
         obligation to guarantee the Securities, and

                                      -92-

                  (iv) in the case of clause (b)(i) above, such Subsidiary
         Guarantor being released from its guarantees, if any, of, and all
         pledges and security, if any, granted in connection with, the Credit
         Agreement and any other Indebtedness of Holdings or any Restricted
         Subsidiary of Holdings.

         A Senior Guarantee also shall be automatically released upon the
applicable Subsidiary ceasing to be a Subsidiary as a result of any foreclosure
of any pledge or security interest securing Bank Indebtedness or other exercise
of remedies in respect thereof or if such Subsidiary is released from its
guarantees of, and all pledges and security interests granted in connection
with, the Credit Agreement and any other Indebtedness of Holdings or any
Restricted Subsidiary of Holdings which results in the obligation to guarantee
the Securities.

         SECTION 10.03. Successors and Assigns. This Article 10 shall be binding
upon each Guarantor and its successors and assigns and shall inure to the
benefit of the successors and assigns of the Trustee and the Holders and, in the
event of any transfer or assignment of rights by any Holder or the Trustee, the
rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

         SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article 10 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 10 at law,
in equity, by statute or otherwise.

         SECTION 10.05. Modification. No modification, amendment or waiver of
any provision of this Article 10, nor the consent to any departure by any
Guarantor therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Trustee, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice or demand in the same, similar or other
circumstances.

         SECTION 10.06. Execution of Supplemental Indenture for Future
Guarantors. Each Subsidiary and other Person which is required to become a
Guarantor pursuant to Section 4.11 shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Exhibit F hereto pursuant to
which such Subsidiary or other Person shall become a Guarantor under this
Article 10 and shall guarantee the Guaranteed Obligations. Concurrently with the
execution and delivery of such supplemental indenture, the Company shall deliver
to the Trustee an Opinion of Counsel and an Officers' Certificate to the effect
that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary or other Person and that, subject to the
application of bankruptcy, insolvency, moratorium, fraudulent conveyance or
transfer and other similar laws relating to creditors' rights generally and to
the principles of equity, whether considered in a

                                      -93-

proceeding at law or in equity, the Senior Guarantee of such Guarantor is a
legal, valid and binding obligation of such Guarantor, enforceable against such
Guarantor in accordance with its terms and/or to such other matters as the
Trustee may reasonably request.

         SECTION 10.07. Non-Impairment. The failure to endorse a Senior
Guarantee on any Security shall not affect or impair the validity thereof.

imposed duties or incorporated provision shall control.

         SECTION 11.02. Notices. (a) Any notice or communication required or
permitted hereunder shall be in writing and delivered in person, via facsimile

                                    if to the Company or a Guarantor:

first class mail, to the Holder at the Holder's address as it appears on the
registration books of the Registrar and shall be sufficiently given if so mailed
within the time prescribed. So long as the Euro Securities are listed on the
Luxembourg Stock Exchange and it is required by the rules of the Luxembourg
Stock Exchange, such notice to the Holders of the Euro Securities will be

Luxembourg

                                      -94-

(which is expected to be the Luxemburger Wort) or, if such publication is not
practicable, in one other leading English language daily newspaper with general
circulation in Europe, such newspaper being published on each business day in
morning editions, whether or not it shall be published in Saturday, Sunday or
holiday editions.

         (c) Failure to mail a notice or communication to a Holder or any defect
in it shall not affect its sufficiency with respect to other Holders. If a
notice or communication is mailed in the manner provided above, it is duly
given, whether or not the addressee receives it, except that notices to the
Trustee are effective only if received.

         SECTION 11.03. Communication by the Holders with Other Holders. The
Holders may communicate pursuant to Section 312(b) of the TIA with other Holders
with respect to their rights under this Indenture or the Securities. The
Company, the Trustee, the Registrar and other Persons shall have the protection
of Section 312(c) of the TIA.

         SECTION 11.04. Certificate and Opinion as to Conditions Precedent. Upon
any request or application by the Company to the Trustee to take or refrain from
taking any action under this Indenture, the Company shall furnish to the Trustee
at the request of the Trustee:

                  (a) an Officers' Certificate in form reasonably satisfactory
         to the Trustee stating that, in the opinion of the signers, all
         conditions precedent, if any, provided for in this Indenture relating
         to the proposed action have been complied with; and

                  (b) an Opinion of Counsel in form reasonably satisfactory to
         the Trustee stating that, in the opinion of such counsel, all such
         conditions precedent have been complied with.

         SECTION 11.05. Statements Required in Certificate or Opinion. Each
certificate or opinion with respect to compliance with a covenant or condition
provided for in this Indenture (other than pursuant to Section 4.09) shall
include:

                  (a) a statement that the individual making such certificate or
         opinion has read such covenant or condition;

                  (b) a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (c) a statement that, in the opinion of such individual, he
         has made such examination or investigation as is necessary to enable
         him to express an informed opinion as to whether or not such covenant
         or condition has been complied with; and

                  (d) a statement as to whether or not, in the opinion of such
         individual, such covenant or condition has been complied with;
         provided, however, that with respect to matters of fact an Opinion of
         Counsel may rely on an Officers' Certificate or certificates of public
         officials.

                                      -95-

         SECTION 11.06. When Securities Disregarded. In determining whether the
Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company, any Guarantor or
by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any Guarantor shall be
disregarded and deemed not to be outstanding, except that, for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which the Trustee knows are so
owned shall be so disregarded. Subject to the foregoing, only Securities
outstanding at the time shall be considered in any such determination.

         SECTION 11.07. Rules by Trustee, Paying Agent and Registrar. The
Trustee may make reasonable rules for action by or a meeting of the Holders. The
Registrar and a Paying Agent may make reasonable rules for their functions.

         SECTION 11.08. Legal Holidays. If a payment date is not a Business Day,
payment shall be made on the next succeeding day that is a Business Day, and no
interest shall accrue on any amount that would have been otherwise payable on
such payment date if it were a Business Day for the intervening period. If a
regular record date is not a Business Day, the record date shall not be
affected.

         SECTION 11.09. GOVERNING LAW. THIS INDENTURE AND THE SECURITIES SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK.

         SECTION 11.10. No Recourse Against Others. No director, officer,
employee, incorporator or holder of any equity interests in the Company (other
than Holdings) or of any Guarantor or any direct or indirect parent corporation,
as such, shall have any liability for any obligations of the Company or the
Guarantors under the Securities or this Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder of
Securities by accepting a Security waives and releases all such liability.

         SECTION 11.11. Successors. All agreements of the Company and each
Guarantor in this Indenture and the Securities shall bind its successors. All
agreements of the Trustee in this Indenture shall bind its successors.

         SECTION 11.12. Multiple Originals. The parties may sign any number of
copies of this Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement. One signed copy is enough to prove this
Indenture.

         SECTION 11.13. Table of Contents; Headings. The table of contents,
cross-reference sheet and headings of the Articles and Sections of this
Indenture have been inserted for convenience of reference only, are not intended
to be considered a part hereof and shall not modify or restrict any of the terms
or provisions hereof.

                                      -96-

         SECTION 11.14. Indenture Controls. If and to the extent that any
provision of the Securities limits, qualifies or conflicts with a provision of
this Indenture, such provision of this Indenture shall control.

         SECTION 11.15. Severability. In case any provision in this Indenture
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby and such provision shall be ineffective only to the extent of
such invalidity, illegality or unenforceability.

         SECTION 11.16. Currency of Account; Conversion of Currency; Foreign
Exchange Restrictions. (a) U.S. Dollars are the sole currency of account and
payment for all sums payable by the Company and the Guarantors under or in
connection with the Dollar Securities, the Senior Guarantees of the Dollar
Securities or this Indenture to the extent it relates to the Dollar Securities,
including damages related thereto, and Euros are the sole currency of account
and payment for all sums payable by the Company and the Guarantors under or in
connection with the Euro Securities, the Senior Guarantees of the Euro
Securities or this Indenture to the extent it relates to the Euro Securities,
including damages related thereto. Any amount received or recovered in a
currency other than U.S. Dollars by a Holder of Dollar Securities or Euro by a
Holder of Euro Securities (whether as a result of, or of the enforcement of, a
judgment or order of a court of any jurisdiction, in the winding-up or
dissolution of the Company or otherwise) in respect of any sum expressed to be
due to it from the Company shall only constitute a discharge to the Company to
the extent of the U.S. Dollar or Euro amount, as the case may be, which the
recipient is able to purchase with the amount so received or recovered in that
other currency on the date of that receipt or recovery (or, if it is not
practicable to make that purchase on that date, on the first date on which it is
practicable to do so). If that U.S. Dollar or Euro amount is less than the U.S.
Dollar or Euro amount expressed to be due to the recipient under the applicable
Securities, the Company shall indemnify it against any loss sustained by it as a
result as set forth in Section 11.16(b). In any event, the Company and the
Guarantors shall indemnify the recipient against the cost of making any such
purchase. For the purposes of this Section 11.16, it will be sufficient for the
Holder of a Note to certify in a satisfactory manner (indicating sources of
information used) that it would have suffered a loss had an actual purchase of
U.S. Dollars or Euros, as the case may be, been made with the amount so received
in that other currency on the date of receipt or recovery (or, if a purchase of
U.S. Dollars or Euros, as applicable, on such date had not been practicable, on
the first date on which it would have been practicable, it being required that
the need for a change of date be certified in the manner mentioned above). The
indemnities set forth in this Section 11.16 constitute separate and independent
obligations from other obligations of the Company and the Guarantors, shall give
rise to a separate and independent cause of action, shall apply irrespective of
any indulgence granted by any Holder of the Securities and shall continue in
full force and effect despite any other judgment, order, claim or proof for a
liquidated amount in respect of any sum due under the Securities.

         (b) The Company and the Guarantors, jointly and severally, covenant and
agree that the following provisions shall apply to conversion of currency in the
case of the Securities, the Senior Guarantees and this Indenture:

                                      -97-

                  (1)      (A)      If for the purpose of obtaining judgment in,
                                    or enforcing the judgment of, any court in
                                    any country, it becomes necessary to convert
                                    into a currency (the "Judgment Currency") an
                                    amount due in any other currency (the "Base
                                    Currency"), then the conversion shall be
                                    made at the rate of exchange prevailing on
                                    the Business Day before the day on which the
                                    judgment is given or the order of
                                    enforcement is made, as the case may be
                                    (unless a court shall otherwise determine).

                           (B)      If there is a change in the rate of exchange
                                    prevailing between the Business Day before
                                    the day on which the judgment is given or an
                                    order of enforcement is made, as the case
                                    may be (or such other date as a court shall
                                    determine), and the date of receipt of the
                                    amount due, the Company and the Guarantors
                                    will pay such additional (or, as the case
                                    may be, such lesser) amount, if any, as may
                                    be necessary so that the amount paid in the
                                    Judgment Currency when converted at the rate
                                    of exchange prevailing on the date of
                                    receipt will produce the amount in the Base
                                    Currency originally due.

                  (2) In the event of the winding-up of the Company or any
         Guarantor at any time while any amount or damages owing under the
         Securities, the Senior Guarantees and this Indenture, or any judgment
         or order rendered in respect thereof, shall remain outstanding, the
         Company and the Guarantors shall indemnify and hold the Holders and the
         Trustee harmless against any deficiency arising or resulting from any
         variation in rates of exchange between (i) the date as of which the
         Applicable Currency Equivalent of the amount due or contingently due
         under the Securities, the Senior Guarantees and this Indenture (other
         than under this subsection (b)(2)) is calculated for the purposes of
         such winding-up and (ii) the final date for the filing of proofs of
         claim in such winding-up. For the purpose of this subsection (b)(2),
         the final date for the filing of proofs of claim in the winding-up of
         the Company or any Guarantor shall be the date fixed by the liquidator
         or otherwise in accordance with the relevant provisions of applicable
         law as being the latest practicable date as at which liabilities of the
         Company or such Guarantor may be ascertained for such winding-up prior
         to payment by the liquidator or otherwise in respect thereto.

         (c) The obligations contained in subsections (a), (b)(1)(B) and (b)(2)
of this Section 11.16 shall constitute separate and independent obligations from
the other obligations of the Company and the Guarantors under this Indenture,
shall give rise to separate and independent causes of action against the Company
and the Guarantors, shall apply irrespective of any waiver or extension granted
by any Holder or the Trustee or either of them from time to time and shall
continue in full force and effect notwithstanding any

                                      -98-

judgment or order or the filing of any proof of claim in the winding-up of the
Company or any Guarantor for a liquidated sum in respect of amounts due
hereunder (other than under subsection (b)(2) above) or under any such judgment
or order. Any such deficiency as aforesaid shall be deemed to constitute a loss
suffered by the Holders or the Trustee, as the case may be, and no proof or
evidence of any actual loss shall be required by the Company or any Guarantor or
the liquidator or otherwise or any of them. In the case of subsection (b)(2)
above, the amount of such deficiency shall not be deemed to be reduced by any
variation in rates of exchange occurring between the said final date and the
date of any liquidating distribution.

         (d) The term "rate(s) of exchange" shall mean the rate of exchange
quoted by Reuters at 10:00 a.m. (New York time) for spot purchases of the Base
Currency with the Judgment Currency other than the Base Currency referred to in
subsections (b)(1) and (b)(2) above and includes any premiums and costs of
exchange payable.

                                      -99-

         IN WITNESS WHEREOF, the parties have caused this Indenture to be duly
executed as of the date first written above.

         Security in an amount equal to the beneficial interest to be
         transferred or exchanged and (2) instructions given in accordance with
         the applicable rules and procedures of the Depository containing

         Global Dollar Security may be transferred to a Person who takes
         delivery thereof in the form of a beneficial interest in another
         Transfer Restricted Global Dollar Security and (y) a Transfer
         Restricted Global Euro Security may be transferred to a Person who

                  in the form attached to the applicable Security,

         and, in each such case, if the Registrar so requests or if the
         applicable rules and procedures of the Depository, Euroclear or
         Clearstream, as applicable, so require, an Opinion of Counsel in form
         reasonably acceptable to the Registrar to the effect that such exchange
         or transfer is in compliance with the Securities Act and that the
         restrictions on transfer contained herein and in the Restricted

                  Security for an Unrestricted Definitive Security, a
                  certificate from such Holder in the form attached to the
                  applicable Security; or

                           (2) if the Holder of such Transfer Restricted
                  Security proposes to transfer such Securities to a Person who
                  shall take delivery thereof in the form of an Unrestricted
                  Definitive Security, a certificate from such Holder in the
                  form attached to the applicable Security,

         and, in each such case, if the Registrar so requests, an Opinion of
         Counsel in form reasonably acceptable to the Company to the effect that
         such exchange or transfer is in compliance with the Securities Act and
         that the restrictions on transfer contained herein and in the
         Restricted Securities Legend are no longer required in order to
         maintain compliance with the Securities Act.

                  (iii) Unrestricted Definitive Securities to Unrestricted
         Definitive Securities. A Holder of an Unrestricted Definitive Security
         may transfer such Unrestricted Definitive Securities to a Person who
         takes delivery thereof in the form of an Unrestricted Definitive
         Security at any time. Upon receipt of a request to register such a
         transfer, the Registrar shall register the Unrestricted Definitive
         Securities pursuant to the instructions from the Holder thereof.

                  (iv) Unrestricted Definitive Securities to Transfer Restricted
         Securities. An Unrestricted Definitive Security cannot be exchanged
         for, or transferred to a Person who takes delivery thereof in the form
         of, a Transfer Restricted Security.

                                      -11-

         At such time as all beneficial interests in a particular Global
Security have been exchanged for Definitive Securities or a particular Global
Security has been redeemed, repurchased or canceled in whole and not in part,
each such Global Security shall be returned to or retained and canceled by the
Trustee in accordance with Section 2.11. At any time prior to such cancellation,
if any beneficial interest in a Global Security is exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Security or for Definitive Securities, the principal amount of
Securities represented by such Global Security shall be reduced accordingly and
an endorsement shall be made on such Global Security by the Trustee or by the
Depository or the Common Depository, as applicable, at the direction of the
Trustee to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Security, such other Global
Security shall be increased accordingly and an endorsement shall be made on such
Global Security by the Trustee or by the Depository or the Common Depository, as
applicable, at the direction of the Trustee to reflect such increase.

         (f) Legend.

of such Transfer Restricted Security if the Holder certifies in writing to the
Registrar that its request for such exchange was made in reliance on Rule 144
(such certification to be in the form set forth on the reverse of the Initial
Security).

                                      -13-

         (iii) After a transfer of any Initial Securities during the period of

Securities, all requirements pertaining to the Restricted Securities Legend on
such Initial Securities shall cease to apply and the requirements that any such
Initial Securities be issued in global form shall continue to apply.

         (iv) Upon the consummation of a Registered Exchange Offer with respect

Definitive Securities or a particular Global Security has been redeemed,
repurchased or canceled in whole and not in part, each such Global Security
shall be returned to or retained and canceled by the Trustee in accordance with
Section 2.11 of this Indenture. At any time prior to such cancellation, if any
beneficial interest in a Global Security is exchanged for or transferred to a
Person who will take delivery thereof in the form of a beneficial interest in
another Global Security or for Definitive Securities, the principal amount of
Securities represented by such Global Security shall be reduced accordingly and
an endorsement shall be made on such Global Security by the Trustee or by the
Depository or the Common Depository, as applicable, at the direction of the
Trustee to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Security, such other Global
Security shall be increased accordingly and an endorsement shall be made on such
Global Security by the Trustee or by the Depository or the Common Depository, as

shall execute and the Trustee shall authenticate, Definitive Securities and
Global Securities at the Registrar's request.

         (ii) No service charge shall be made for any registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any transfer tax, assessments, or similar governmental charge payable in
connection therewith (other than any

                                      -14-

such transfer taxes, assessments or similar governmental charge payable upon
exchanges pursuant to Sections 3.06, 4.06, 4.08 and 9.05 of this Indenture).

         (iii) Prior to the due presentation for registration of transfer of any

treat the person in whose name a Security is registered as the absolute owner of
such Security for the purpose of receiving payment of principal of and interest
on such Security and for all other purposes whatsoever, whether or not such
Security is overdue, and none of the Company, the Trustee, a Paying Agent or the
Registrar shall be affected by notice to the contrary.

         (iv) All Securities issued upon any transfer or exchange pursuant to
the terms of this Indenture shall evidence the same debt and shall be entitled
to the same benefits under this Indenture as the Securities surrendered upon
such transfer or exchange.

         (i) The Trustee shall have no responsibility or obligation to any
beneficial owner of a Global Security, a member of, or a participant in the
Depository or any other Person with respect to the accuracy of the records of

delivery to any participant, member, beneficial owner or other Person (other
than the Depository) of any notice (including any notice of redemption or
repurchase) or the payment of any amount, under or with respect to such
Securities. All notices and communications to be given to the Holders and all
payments to be made to the Holders under the Securities shall be given or made
only to the registered Holders (which shall be the Depository or its nominee in
the case of a Global Security). In addition, for so long as the Securities are
listed on the Luxembourg Stock Exchange and the rules of such securities
exchange so require, notices to the Holders of the Securities shall be published
in a newspaper having a general circulation in Luxembourg (which is expected to
be the Luxemburger Wort). The rights of beneficial owners in any Global Security
shall be exercised only through the Depository subject to the applicable rules
and procedures of the Depository. The Trustee may rely and shall be fully
protected in relying upon information furnished by the Depository with respect
to its members, participants and any beneficial owners.

         (ii) The Trustee shall have no obligation or duty to monitor, determine
or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest
in any Security (including any transfers between or among Depository
participants, members or beneficial owners in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

1.   Interest

         (a) NALCO COMPANY, a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Dollar Security at the rate per annum shown above. The Company shall pay
interest semiannually on May 15 and November 15 of each year, commencing May 15,
2004. Interest on the Dollar Securities shall accrue from the most recent date
to which interest has been paid or duly provided for or, if no interest has been
paid or duly provided for, from November 4, 2003 until the principal hereof is
due. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Dollar Securities, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.

         (b) Registration Rights Agreement. The Holder of this Dollar Security
is entitled to the benefits of a Registration Rights Agreement, dated as of
November 4, 2003, among the Company, the Guarantors and the Initial Purchasers.

2.   Method of Payment

         The Company shall pay interest on the Dollar Securities (except
defaulted interest) to the Persons who are registered Holders at the close of
business on the May 1 or November 1 next preceding the interest payment date
even if Dollar Securities are canceled after the record date and on or before
the interest payment date (whether or not a Business Day). The Holders must
surrender Securities to a Paying Agent to collect principal payments. The
Company shall pay principal, premium, if any, and interest in money of the
United States of America that at the time of payment is legal tender for payment
of public and private debts. Payments in respect of the Dollar Securities
represented by a Global Dollar Security (including principal, premium, if any,
and interest) shall be made by wire transfer of immediately available funds to
the accounts specified by The Depository Trust Company or any successor
depositary. The Company will make all payments in respect of a certificated
Dollar Security (including principal, premium, if any, and interest), at the
office of each Paying Agent, except that, at the option of the Company, payment
of interest may be made by mailing a check to the registered address of each
Holder thereof; provided, however, that payments on the Dollar Securities may
also be made, in the case of a Holder of at least $1,000,000 aggregate principal
amount of Dollar Securities, by wire transfer to a U.S. dollar account
maintained by the payee with a bank in the United States if such Holder elects
payment by wire transfer by giving written notice to the Trustee or a Paying
Agent to such effect designating such account no later than 30 days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

3.   Paying Agent and Registrar

         Initially, The Bank of New York, a New York banking corporation (the
"Trustee"), will act as Dollar Paying Agent and Registrar. The Company may
appoint and

                                      -5-

change any Paying Agent or Registrar without notice. The Company or
any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying
Agent or Registrar.

4.   Indenture

         The Company issued the Dollar Securities under an Indenture dated as of
November 4, 2003 (the "Indenture"), among the Company, the Guarantors and the
Trustee. The terms of the Dollar Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. (sections)77aaa-77bbbb) as in effect on the
date of the Indenture (the "TIA"). Terms defined in the Indenture and not
defined herein have the meanings ascribed thereto in the Indenture. The Dollar
Securities are subject to all terms and provisions of the Indenture, and the
Holders (as defined in the Indenture) are referred to the Indenture and the TIA
for a statement of such terms and provisions

         The Dollar Securities are senior unsecured obligations of the Company.
This Dollar Security is one of the Initial Dollar Securities referred to in the
Indenture. The Dollar Securities include the Initial Dollar Securities and any
Exchange Dollar Securities issued in exchange for Initial Dollar Securities
pursuant to the Indenture. The Initial Dollar Securities and any Exchange Dollar
Securities together with the Initial Euro Securities and any Exchange Euro
Securities are treated as a single class of securities under the Indenture. The
Indenture imposes certain limitations on the ability of Holdings and its
Restricted Subsidiaries to, among other things, make certain Investments and
other Restricted Payments, pay dividends and other distributions, incur
Indebtedness, enter into consensual restrictions upon the payment of certain
dividends and distributions by such Restricted Subsidiaries, issue or sell
shares of capital stock of Holdings and such Restricted Subsidiaries, enter into
or permit certain transactions with Affiliates, create or incur Liens and make
asset sales. The Indenture also imposes limitations on the ability of the
Company and each Guarantor to consolidate or merge with or into any other Person
or convey, transfer or lease all or substantially all of its property.

         To guarantee the due and punctual payment of the principal and
interest, on the Dollar Securities and all other amounts payable by the Company
under the Indenture and the Dollar Securities when and as the same shall be due
and payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Dollar Securities and the Indenture, the Guarantors have, jointly
and severally, unconditionally guaranteed the Guaranteed Obligations on a senior

prices (expressed as a percentage of principal amount), plus accrued and unpaid

of the years set forth below:

                  YEAR                                   REDEMPTION PRICE
                  ----                                   ----------------
                  2007                                       103.875%
                  2008                                       101.938%
                  2009 and thereafter                        100.000%

         In addition, prior to November 15, 2007, the Company may redeem the
Dollar Securities at its option, in whole at any time or in part from time to
time, upon not less than 30 nor more than 60 days' prior notice mailed by
first-class mail to each Holder's registered address, at a redemption price
equal to 100% of the principal amount of the Dollar Securities redeemed plus the
Applicable Premium as of, and accrued and unpaid interest, to, the applicable
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

         Notwithstanding the foregoing, at any time and from time to time on or
prior to November 15, 2006, the Company may redeem in the aggregate up to 35% of
the original aggregate principal amount of the Dollar Securities (calculated
after giving effect to any issuance of Additional Dollar Securities) with the
net cash proceeds of one or more Equity Offerings (1) by the Company or (2) by
Holdings or any direct or indirect parent of Holdings or the Company, in each
case, to the extent the net cash proceeds thereof are contributed to the common
equity capital of the Company or used to purchase Capital Stock (other than
Disqualified Stock) of the Company from it, at a redemption price equal to
107.75% of the principal amount thereof plus, accrued and unpaid interest, to
the redemption date (subject to the right of the Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date); provided, however, that at least 65% of the original aggregate principal
amount of the Dollar Securities (calculated after giving effect to any issuance
of Additional Dollar Securities) must remain outstanding after each such
redemption; and provided, further, that such redemption shall occur within 90
days after the date on which any such Equity Offering is consummated upon not
less than 30 nor more than 60 days' notice mailed to each Holder of Securities
being redeemed and otherwise in accordance with the procedures set forth in the
Indenture.

6.   Sinking Fund

         The Dollar Securities are not subject to any sinking fund.

7.   Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Dollar Securities to be redeemed at his, her or its registered address. Dollar
Securities in denominations larger than $1,000 may be redeemed in part but only
in whole multiples of $1,000. If money sufficient to pay the redemption price of
and accrued and unpaid interest on all Dollar Securities (or portions thereof)
to be redeemed on the redemption date is deposited with a Paying Agent on or
before the redemption date and certain other conditions are satisfied, on and
after such date, interest ceases to accrue on such Dollar Securities (or such
portions thereof) called for redemption.

                                      -7-

8.   Repurchase of Dollar Securities at the Option of Holders
     upon Change of Control and Asset Sales

         Upon the occurrence of a Change of Control, each Holder shall have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of such Holder's Dollar Securities at a
purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of repurchase (subject to the
right of the Holders of record on the relevant record date to receive interest
due on the relevant interest payment date), as provided in, and subject to the
terms of, the Indenture.

         In accordance with Section 4.06 of the Indenture, the Company will be
required to offer to purchase Dollar Securities upon the occurrence of certain
events.

9.   Denominations; Transfer; Exchange

         The Dollar Securities are in registered form, without coupons, in
denominations of $1,000 and whole multiples of $1,000. A Holder shall register
the transfer of or exchange of Dollar Securities in accordance with the
Indenture. Upon any registration of transfer or exchange, the Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Dollar Securities selected for redemption (except, in the case of a
Dollar Security to be redeemed in part, the portion of the Dollar Security not
to be redeemed) or to transfer or exchange any Dollar Securities for a period of
15 days prior to a selection of Dollar Securities to be redeemed.

10.  Persons Deemed Owners

         The registered Holder of this Dollar Security shall be treated as the
owner of it for all purposes.

11.  Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee and a Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, the Holders entitled to the money must
look to the Company for payment as general creditors and the Trustee and a
Paying Agent shall have no further liability with respect to such monies.

12.  Discharge and Defeasance

                  Subject to certain conditions, the Company at any time may
terminate some of or all its obligations under the Dollar Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal of, and interest on the Dollar
Securities to redemption, or maturity, as the case may be.

                                      -8-

13.      Amendment, Waiver

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the outstanding
Securities (voting as a single class) and (ii) any past default or compliance
with any provisions may be waived with the written consent of the Holders of at
least a majority in principal amount of the outstanding Securities; provided,
however, that if any amendment, waiver or other modification will only affect
the Dollar Securities or the Euro Securities, only the consent of the Holders of
at least a majority in principal amount of the then outstanding Dollar
Securities or Euro Securities (and not the consent of the Holders of at least a
majority of all Securities), as the case may be, shall be required. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Holder, the Company and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply
with Article 5 of the Indenture; (iii) to provide for uncertificated Securities
in addition to or in place of certificated Securities; (iv) to add Senior
Guarantees with respect to the Securities; (v) to add additional covenants of
the Company or Holdings for the benefit of the Holders or to surrender rights
and powers conferred on the Company; (vi) to comply with the requirements of the
SEC in order to effect or maintain the qualification of the Indenture under the
TIA; (vii) to make any change that does not adversely affect the rights of any
Holder; or (viii) to provide for the issuance of the Exchange Securities or
Additional Securities.

14.  Defaults and Remedies

         If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of Holdings or the
Company) and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Securities, in each case, by notice to the
Company, may declare the principal of, premium, if any, and accrued but unpaid
interest on all the Securities to be due and payable. If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of
Holdings or the Company occurs, the principal of, premium, if any, and interest
on all the Securities shall become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. Under
certain circumstances, the Holders of a majority in principal amount of the
outstanding Securities may rescind any such acceleration with respect to the
Securities and its consequences.

         If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense and certain other conditions are complied with. Except to
enforce the right to receive payment of principal, premium (if any) or interest
when due, no Holder may pursue any remedy with respect to the Indenture or the
Securities unless (i) such Holder has previously given the Trustee notice that
an Event of Default is continuing, (ii) the Holders of at least 25% in principal
amount of the outstanding Securities have requested the Trustee in writing to
pursue the remedy, (iii) such Holders have offered the Trustee reasonable
security or indemnity against any loss, liability or expense, (iv) the Trustee
has not complied with such request within 60 days after the receipt of the
request and the offer of

                                      -9-

security or indemnity and (v) the Holders of a majority in principal amount of
the outstanding Securities have not given the Trustee a direction inconsistent
with such request within such 60-day period. Subject to certain restrictions,
the Holders of a majority in principal amount of the outstanding Securities are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability. Prior to taking any action under the
Indenture, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

15.  Trustee Dealings with the Company

         Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16.  No Recourse Against Others

         No director, officer, employee, incorporator or holder of any equity
interests in the Company (other than Holdings) or of any Guarantor or any direct
or indirect parent corporation, as such, shall have any liability for any
obligations of the Company or the Guarantors under the Securities, the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder of Securities by accepting a Security waives and
releases all such liability.

17.  Authentication

         This Dollar Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Dollar Security.

18.   Abbreviations

         Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

19.  Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK.

                                      -10-

20.  CUSIP Numbers, ISINs and Common Codes

         The Company has caused CUSIP numbers and ISINs and, in the case of the
Euro Securities, Common Codes, to be printed on the Securities and has directed
the Trustee to use CUSIP numbers and ISINs and, in the case of the Euro
Securities, Common Codes, in notices of redemption as a convenience to the
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Securities or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

         THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON WRITTEN
REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH HAS IN IT
THE TEXT OF THIS SECURITY.

1.   Interest

         (a) NALCO COMPANY, a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Euro Security at the rate per annum shown above. The Company shall pay interest
semiannually on May 15 and November 15 of each year, commencing May 15, 2004.
Interest on the Euro Securities shall accrue from the most recent date to which
interest has been paid or duly provided for or, if no interest has been paid or
duly provided for, from November 4, 2003 until the principal hereof is due.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Euro Securities, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.

         (b) Registration Rights Agreement. The Holder of this Euro Security is
entitled to the benefits of a Registration Rights Agreement, dated as of
November 4, 2003, among the Company, the Guarantors and the Initial Purchasers
named therein.

2.   Method of Payment

         The Company shall pay interest on the Euro Securities (except defaulted
interest) to the Persons who are registered Holders at the close of business on
the May 1 or November 1 next preceding the interest payment date even if Euro
Securities are canceled after the record date and on or before the interest
payment date. The Holders must surrender Euro Securities to a Paying Agent to
collect principal payments. The Company shall pay principal, premium, if any,
and interest in money of a member state of the European Union that at the time
of payment is legal tender for payment of public and private debts. Payments in
respect of the Euro Securities represented by a Global Security (including
principal, premium, if any, and interest) shall be made by wire transfer of
immediately available funds to the accounts specified by The Depository Trust
Company or any successor depositary. The Company will make all payments in
respect of a certificated Euro Security (including principal, premium, if any,
and interest), at the office of a Paying Agent, except that, at the option of
the Company, payment of interest may be made by mailing a check to the
registered address of each Holder thereof; provided, however, that payments on
the Euro Securities may also be made, in the case of a Holder of at least
(Euro)1,000,000 aggregate principal amount of Euro Securities, by wire transfer
to a Euro account maintained by the payee with a bank in member state of the
European Union if such Holder elects payment by wire transfer by giving written
notice to the Trustee or a Paying Agent to such effect designating such account
no later than 30 days immediately preceding the relevant due date for payment
(or such other date as the Trustee may accept in its discretion).

3.   Paying Agent and Registrar

         Initially, The Bank of New York, London Branch will act as Euro Paying
Agent. The Company may appoint and change any Paying Agent or Registrar without
notice. The

                                      -5-

Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent or Registrar.

4.   Indenture

         The Company issued the Euro Securities under an Indenture dated as of
November 4, 2003 (the "Indenture"), among the Company, the Guarantors and The
Bank of New York, a New York banking corporation (the "Trustee"). The terms of
the Euro Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss.
77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA"). Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Euro Securities are subject to all terms and
provisions of the Indenture, and the Holders (as defined in the Indenture) are
referred to the Indenture and the TIA for a statement of such terms and
provisions

         The Euro Securities are senior unsecured obligations of the Company.
This Euro Security is one of the Initial Euro Securities referred to in the
Indenture. The Euro Securities include the Initial Euro Securities and any
Exchange Euro Securities issued in exchange for Initial Euro Securities pursuant
to the Indenture. The Initial Euro Securities and any Exchange Euro Securities
together with the Initial Dollar Securities and the Exchange Dollar Securities
are treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of Holdings and its Restricted
Subsidiaries to, among other things, make certain Investments and other
Restricted Payments, pay dividends and other distributions, incur Indebtedness,
enter into consensual restrictions upon the payment of certain dividends and
distributions by such Restricted Subsidiaries, issue or sell shares of capital
stock of Holdings and such Restricted Subsidiaries, enter into or permit certain
transactions with Affiliates, create or incur Liens and make asset sales. The
Indenture also imposes limitations on the ability of the Company and each
Guarantor to consolidate or merge with or into any other Person or convey,
transfer or lease all or substantially all of its property.

         To guarantee the due and punctual payment of the principal and interest
on the Euro Securities and all other amounts payable by the Company under the
Indenture and the Euro Securities when and as the same shall be due and payable,
whether at maturity, by acceleration or otherwise, according to the terms of the
Euro Securities and the Indenture, the Guarantors have, jointly and severally,
unconditionally guaranteed the Guaranteed Obligations on a senior basis pursuant
to the terms of the Indenture.

5.   Optional Redemption.

         Except as set forth in the following two paragraphs, the Euro
Securities shall not be redeemable at the option of the Company prior to
November 15, 2007. Thereafter, the Euro Securities shall be redeemable at the
option of the Company, in whole at any time or in part from time to time, upon
on not less than 30 nor more than 60 days' prior notice, at the following
redemption prices (expressed as a percentage of principal amount), plus accrued
and unpaid interest to the redemption date (subject to the right of the Holders
of record on the relevant record date to receive interest due on the relevant
interest payment date), if redeemed during the 12-month period commencing on
November 15 of the years set forth below:

                                      -6-

                  YEAR                               REDEMPTION PRICE
                  ----                               ----------------
                  2007                                   103.875%
                  2008                                   101.938%
                  2009 and thereafter                    100.000%

         In addition, prior to November 15, 2007, the Company may redeem the
Euro Securities, at its option, in whole at any time or in part from time to
time, upon not less than 30 nor more than 60 days' prior notice mailed by
first-class mail to each Holder's registered address, at a redemption price
equal to 100% of the principal amount of the Euro Securities redeemed plus the
Applicable Premium as of, and accrued and unpaid interest to, the applicable
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

         Notwithstanding the foregoing, at any time and from time to time on or
prior to November 15, 2006, the Company may redeem in the aggregate up to 35% of
the original aggregate principal amount of the Euro Securities (calculated after
giving effect to any issuance of Additional Euro Securities) with the net cash
proceeds of one or more Equity Offerings (1) by the Company or (2) by Holdings
or any direct or indirect parent of Holdings or the Company, in each case, to
the extent the net cash proceeds thereof are contributed to the common equity
capital of the Company or used to purchase Capital Stock (other than
Disqualified Stock) of the Company from it, at a redemption price equal to
107.75% of the principal amount thereof, plus accrued and unpaid interest to the
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that at least 65% of the original aggregate principal amount
of the Euro Securities (calculated after giving effect to any issuance of
Additional Euro Securities) must remain outstanding after each such redemption;
and provided, further, that such redemption shall occur within 90 days after the
date on which any such Equity Offering is consummated upon not less than 30 nor
more than 60 days' notice mailed to each Holder of Securities being redeemed and
otherwise in accordance with the procedures set forth in the Indenture.

6.   Sinking Fund

         The Euro Securities are not subject to any sinking fund.

7.   Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of Euro
Securities to be redeemed at his, her or its registered address. Euro Securities
in denominations larger than (Euro)1,000 may be redeemed in part but only in
whole multiples of (Euro)1,000. If money sufficient to pay the redemption price
of and accrued and unpaid interest on all Euro Securities (or portions thereof)
to be redeemed on the redemption date is deposited with a Paying Agent on or
before the redemption date and certain other conditions are satisfied, on and
after such date interest ceases to accrue on such Euro Securities (or such
portions thereof) called for redemption.

                                      -7-

8.   Repurchase of Euro Securities at the Option of the Holders
     upon Change of Control and Asset Sales

         Upon the occurrence of a Change of Control, each Holder shall have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of such Holder's Euro Securities at a
purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of repurchase (subject to the
right of the Holders of record on the relevant record date to receive interest
due on the relevant interest payment date), as provided in, and subject to the
terms of, the Indenture.

         In accordance with Section 4.06 of the Indenture, the Company will be
required to offer to purchase Euro Securities upon the occurrence of certain
events.

9.   Denominations; Transfer; Exchange

         The Euro Securities are in registered form, without coupons, in
denominations of (Euro)1,000 and whole multiples of (Euro)1,000. A Holder shall
register the transfer of or exchange of Euro Securities in accordance with the
Indenture. Upon any registration of transfer or exchange, the Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Euro Securities selected for redemption (except, in the case of a
Euro Security to be redeemed in part, the portion of the Euro Security not to be
redeemed) or to transfer or exchange any Euro Securities for a period of 15 days
prior to a selection of Securities to be redeemed.

10.  Persons Deemed Owners

         The registered Holder of this Euro Security shall be treated as the
owner of it for all purposes.

11.  Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee and a Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, the Holders entitled to the money must
look to the Company for payment as general creditors and the Trustee and a
Paying Agent shall have no further liability with respect to such monies.

12.  Discharge and Defeasance

                  Subject to certain conditions, the Company at any time may
terminate some of or all its obligations under the Securities and the Indenture
if the Company deposits with the Trustee money or EU Government Obligations for
the payment of principal of, and interest on the Securities to redemption, or
maturity, as the case may be.

                                      -8-

13.  Amendment, Waiver

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the outstanding
Securities (voting as a single class) and (ii) any past default or compliance
with any provisions may be waived with the written consent of the Holders of at
least a majority in principal amount of the outstanding Securities; provided,
however, that if any amendment, waiver or other modification will only affect
the Dollar Securities or the Euro Securities, only the consent of the Holders of
at least a majority in principal amount of the then outstanding Dollar
Securities or Euro Securities (and not the consent of the Holders of at least a
majority of all Securities), as the case may be, shall be required. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Holder, the Company and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply
with Article 5 of the Indenture; (iii) to provide for uncertificated Securities
in addition to or in place of certificated Securities; (iv) to add Senior
Guarantees with respect to the Securities; (v) to add additional covenants of
the Company or Holdings for the benefit of the Holders or to surrender rights
and powers conferred on the Company; (vi) to comply with the requirements of the
SEC in order to effect or maintain the qualification of the Indenture under the
TIA; (vii) to make any change that does not adversely affect the rights of any
Holder; or (viii) to provide for the issuance of the Exchange Securities or
Additional Securities.

14.  Defaults and Remedies

         If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of Holdings or the
Company) and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Securities, in each case, by notice to the
Company, may declare the principal of, premium, if any, and accrued but unpaid
interest on all the Securities to be due and payable. If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of
Holdings or the Company occurs, the principal of, premium, if any, and interest
on all the Securities shall become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. Under
certain circumstances, the Holders of a majority in principal amount of the
outstanding Securities may rescind any such acceleration with respect to the
Securities and its consequences.

         If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense and certain other conditions are complied with. Except to
enforce the right to receive payment of principal, premium (if any) or interest
when due, no Holder may pursue any remedy with respect to the Indenture or the
Securities unless (i) such Holder has previously given the Trustee notice that
an Event of Default is continuing, (ii) the Holders of at least 25% in principal
amount of the outstanding Securities have requested the Trustee in writing to
pursue the remedy, (iii) such Holders have offered the Trustee reasonable
security or indemnity against any loss, liability or expense, (iv) the Trustee
has not complied with such request within 60 days after the receipt of the
request and the offer of

                                      -9-

security or indemnity and (v) the Holders of a majority in principal amount of
the outstanding Securities have not given the Trustee a direction inconsistent
with such request within such 60-day period. Subject to certain restrictions,
the Holders of a majority in principal amount of the outstanding Securities are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability. Prior to taking any action under the
Indenture, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

15.  Trustee Dealings with the Company

         Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16.  No Recourse Against Others

         No director, officer, employee, incorporator or holder of any equity
interests in the Company (other than Holdings) or of any Guarantor or any direct
or indirect parent corporation, as such, shall have any liability for any
obligations of the Company or the Guarantors under the Securities, the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder of Securities by accepting a Security waives and
releases all such liability.

17.  Authentication

         This Euro Security shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Euro Security.

18.  Abbreviations

         Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

19.  Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK.

                                      -10-

20.      CUSIP Numbers, ISINs and Common Codes

         The Company has caused CUSIP numbers and ISINs and, in the case of the
Euro Securities, Common Codes, to be printed on the Securities and has directed
the Trustee to use CUSIP numbers and ISINs and, in the case of the Euro
Securities, Common Codes, in notices of redemption as a convenience to the
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Securities or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

         THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON WRITTEN
REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH HAS IN IT
THE TEXT OF THIS SECURITY.

                           7 3/4% Senior Note due 2011

1.   Interest

         NALCO COMPANY, a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Dollar Security at the rate per annum shown above. The Company shall pay
interest semiannually on May 15 and November 15 of each year, commencing May 15,
2004. Interest on the Dollar Securities shall accrue from the most recent date
to which interest has been paid or duly provided for or, if no interest has been
paid or duly provided for, from November 4, 2003 until the principal hereof is
due. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Dollar Securities, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.

2.   Method of Payment

         The Company shall pay interest on the Dollar Securities (except
defaulted interest) to the Persons who are registered Holders at the close of
business on the May 1 or November 1 next preceding the interest payment date
even if Dollar Securities are canceled after the record date and on or before
the interest payment date (whether or not a Business Day). The Holders must
surrender Dollar Securities to a Paying Agent to collect principal payments. The
Company shall pay principal, premium, if any, and interest in money of the
United States of America that at the time of payment is legal tender for payment
of public and private debts. Payments in respect of the Dollar Securities
represented by a Global Security (including principal, premium and interest)
shall be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company or any successor depositary. The
Company will make all payments in respect of a certificated Dollar Security
(including principal, premium, if any, and interest), at the office of a Paying
Agent, except that, at the option of the Company, payment of interest may be
made by mailing a check to the registered address of each Holder thereof;
provided, however, that payments on the Dollar Securities may also be made, in
the case of a Holder of at least $1,000,000 aggregate principal amount of Dollar
Securities, by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire transfer
by giving written notice to the Trustee or a Paying Agent to such effect
designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in
its discretion).

3.   Paying Agent and Registrar

         Initially, The Bank of New York, a New York banking corporation (the
"Trustee"), will act as Dollar Paying Agent and Registrar. The Company may
appoint and change any Paying Agent or Registrar without notice. The Company or
any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying
Agent or Registrar.

                                      -4-

4.   Indenture

         The Company issued the Dollar Securities under an Indenture dated as of
November 4, 2003 (the "Indenture"), among the Company, the Guarantors and the
Trustee. The terms of the Dollar Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date
of the Indenture (the "TIA"). Terms defined in the Indenture and not defined
herein have the meanings ascribed thereto in the Indenture. The Securities are
subject to all terms and provisions of the Indenture, and the Holders (as
defined in the Indenture) are referred to the Indenture and the TIA for a
statement of such terms and provisions.

         The Dollar Securities are senior unsecured obligations of the Company.
This Security is one of the Exchange Dollar Securities referred to in the
Indenture. The Dollar Securities include the Initial Dollar Securities, the
Additional Dollar Securities and any Exchange Dollar Securities issued in
exchange for the Initial Dollar Securities pursuant to the Indenture. The
Initial Dollar Securities and Exchange Dollar Securities together with the
Initial Euro Securities, and any Exchange Euro Securities are treated as a
single class of securities under the Indenture. The Indenture imposes certain
limitations on the ability of Holdings and its Restricted Subsidiaries to, among
other things, make certain Investments and other Restricted Payments, pay
dividends and other distributions, incur Indebtedness, enter into consensual
restrictions upon the payment of certain dividends and distributions by such
Restricted Subsidiaries, issue or sell shares of capital stock of Holdings and
such Restricted Subsidiaries, enter into or permit certain transactions with
Affiliates, create or incur Liens and make Asset Sales. The Indenture also
imposes limitations on the ability of the Company and each Guarantor to
consolidate or merge with or into any other Person or convey, transfer or lease
all or substantially all of its property.

         To guarantee the due and punctual payment of the principal and
interest, if any, on the Dollar Securities and all other amounts payable by the
Company under the Indenture and the Dollar Securities when and as the same shall
be due and payable, whether at maturity, by acceleration or otherwise, according
to the terms of the Dollar Securities and the Indenture, the Guarantors have,
jointly and severally, unconditionally guaranteed the Guaranteed Obligations on
a senior basis pursuant to the terms of the Indenture.

5.   Optional Redemption

         Except as set forth in the following two paragraphs, the Dollar
Securities shall not be redeemable at the option of the Company prior to
November 15, 2007. Thereafter, the Dollar Securities shall be redeemable at the
option of the Company, in whole at any time or in part from time to time, upon
on not less than 30 nor more than 60 days' prior notice, at the following
redemption prices (expressed as a percentage of principal amount), plus accrued
and unpaid interest, if any, to the redemption date (subject to the right of the
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), if redeemed during the 12-month period
commencing on November 15 of the years set forth below:

                                      -5-

                  YEAR                                   REDEMPTION PRICE
                  ----                                   ----------------
                  2007                                       103.875%
                  2008                                       101.938%
                  2009 and thereafter                        100.000%

         In addition, prior to November 15, 2007, the Company may redeem the
Dollar Securities at its option, in whole at any time or in part from time to
time, upon not less than 30 nor more than 60 days' prior notice mailed by
first-class mail to each Holder's registered address, at a redemption price
equal to 100% of the principal amount of the Dollar Securities redeemed plus the
Applicable Premium as of, and accrued and unpaid interest to, the applicable
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

         Notwithstanding the foregoing, at any time and from time to time on or
prior to November 15, 2006, the Company may redeem in the aggregate up to 35% of
the original aggregate principal amount of the Dollar Securities (calculated
after giving effect to any issuance of Additional Dollar Securities), with the
net cash proceeds of one or more Equity Offerings (1) by the Company or (2) by
Holdings or any direct or indirect parent of Holdings or the Company, in each
case, to the extent the net cash proceeds thereof are contributed to the common
equity capital of the Company or used to purchase Capital Stock (other than
Disqualified Stock) of the Company from it, at a redemption price equal to
107.75% of the principal amount thereof plus accrued and unpaid interest to the
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that at least 65% of the original aggregate principal amount
of the Dollar Securities (calculated after giving effect to any issuance of
Additional Dollar Securities) must remain outstanding after each such
redemption; and provided, further, that such redemption shall occur within 90
days after the date on which any such Equity Offering is consummated upon not
less than 30 nor more than 60 days' notice mailed to each Holder of Securities
being redeemed and otherwise in accordance with the procedures set forth in the
Indenture.

6.   Sinking Fund

         The Dollar Securities are not subject to any sinking fund.

7.   Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of
Dollar Securities to be redeemed at his, her or its registered address. Dollar
Securities in denominations larger than $1,000 may be redeemed in part but only
in whole multiples of $1,000. If money sufficient to pay the redemption price of
and accrued and unpaid interest on all Dollar Securities (or portions thereof)
to be redeemed on the redemption date is deposited with a Paying Agent on or
before the redemption date and certain other conditions are satisfied, on and
after such date interest ceases to accrue on such Dollar Securities (or such
portions thereof) called for redemption.

                                      -6-

8.   Repurchase of Dollar Securities at the Option of the Holders
     upon Change of Control and Asset Sales

         Upon the occurrence of a Change of Control, each Holder shall have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of such Holder's Dollar Securities at a
purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of repurchase (subject to the
right of the Holders of record on the relevant record date to receive interest
due on the relevant interest payment date), as provided in, and subject to the
terms of, the Indenture.

         In accordance with Section 4.06 of the Indenture, the Company will be
required to offer to purchase Dollar Securities upon the occurrence of certain
events.

9.   Denominations; Transfer; Exchange

         The Dollar Securities are in registered form without coupons in
denominations of $1,000 and whole multiples of $1,000. A Holder shall register
the transfer of or exchange of Dollar Securities in accordance with the
Indenture. Upon any registration of transfer or exchange, the Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Dollar Securities selected for redemption (except, in the case of a
Dollar Security to be redeemed in part, the portion of the Dollar Security not
to be redeemed) or to transfer or exchange any Dollar Securities for a period of
15 days prior to a selection of Dollar Securities to be redeemed.

10.  Persons Deemed Owners

         The registered Holder of this Dollar Security shall be treated as the
owner of it for all purposes.

11.  Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee and a Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, the Holders entitled to the money must
look to the Company for payment as general creditors and the Trustee and a
Paying Agent shall have no further liability with respect to such monies.

12.  Discharge and Defeasance

         Subject to certain conditions, the Company at any time may terminate
some of or all its obligations under the Dollar Securities and the Indenture if
the Company deposits with the Trustee money or U.S. Government Obligations for
the payment of principal and interest on the Securities to redemption, or
maturity, as the case may be.

                                      -7-

13.  Amendment, Waiver

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the outstanding
Securities (voting as a single class) and (ii) any past default or compliance
with any provisions may be waived with the written consent of the Holders of at
least a majority in principal amount of the outstanding Securities; provided,
however, that if any amendment, waiver or other modification will only affect
the Dollar Securities or the Euro Securities, only the consent of the Holders of
at least a majority in principal amount of the then outstanding Dollar
Securities or Euro Securities (and not the consent of the Holders of at least a
majority of all Securities), as the case may be, shall be required. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Holder, the Company and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply
with Article 5 of the Indenture; (iii) to provide for uncertificated Securities
in addition to or in place of certificated Securities; (iv) to add Senior
Guarantees with respect to the Securities; (v) to add additional covenants of
the Company or Holdings for the benefit of the Holders or to surrender rights
and powers conferred on the Company; (vi) to comply with the requirements of the
SEC in order to effect or maintain the qualification of the Indenture under the
TIA; (vii) to make any change that does not adversely affect the rights of any
Holder; or (viii) to provide for the issuance of the Exchange Securities or
Additional Securities.

14.  Defaults and Remedies

         If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of Holdings or the
Company) and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Securities, in each case, by notice to the
Company, may declare the principal of, premium, if any, and accrued but unpaid
interest on all the Securities to be due and payable. If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of
Holdings or the Company occurs, the principal of, premium, if any, and interest
on all the Securities shall become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. Under
certain circumstances, the Holders of a majority in principal amount of the
outstanding Securities may rescind any such acceleration with respect to the
Securities and its consequences.

         If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense and certain other conditions are complied with. Except to
enforce the right to receive payment of principal, premium (if any) or interest
when due, no Holder may pursue any remedy with respect to the Indenture or the
Securities unless (i) such Holder has previously given the Trustee notice that
an Event of Default is continuing, (ii) the Holders of at least 25% in principal
amount of the outstanding Securities have requested the Trustee in writing to
pursue the remedy, (iii) such Holders have offered the Trustee reasonable
security or indemnity against any loss, liability or expense, (iv) the Trustee
has not complied with such request within 60 days after the receipt of the
request and the offer of

                                      -8-

security or indemnity and (v) the Holders of a majority in principal amount of
the outstanding Securities have not given the Trustee a direction inconsistent
with such request within such 60-day period. Subject to certain restrictions,
the Holders of a majority in principal amount of the outstanding Securities are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability. Prior to taking any action under the
Indenture, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

15.  Trustee Dealings with the Company

         Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16.  No Recourse Against Others

         No director, officer, employee, incorporator or holder of any equity
interests in the Company (other than Holdings) or of any Guarantor or any direct
or indirect parent corporation, as such, shall have any liability for any
obligations of the Company or the Guarantors under the Securities, the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder of Securities by accepting a Security waives and
releases all such liability.

17.  Authentication

         This Dollar Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Dollar Security.

18.  Abbreviations

         Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

19.  Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,

20.  CUSIP Numbers, ISINs and Common Codes

         The Company has caused CUSIP numbers and ISINs and, in the case of the
Euro Securities, Common Codes to be printed on the Securities and has directed
the Trustee to use CUSIP numbers and ISINs and, in the case of the Euro
Securities, Common Codes, in notices of redemption as a convenience to the
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Securities or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

         THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON WRITTEN
REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH HAS IN IT
THE TEXT OF THIS SECURITY.

                           7 3/4% Senior Note due 2011

1.   Interest

         NALCO COMPANY, a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Security at the rate per annum shown above. The Company shall pay interest
semiannually on May 15 and November 15 of each year, commencing May 15, 2004.
Interest on the Euro Securities shall accrue from the most recent date to which
interest has been paid or duly provided for or, if no interest has been paid or
duly provided for, from November 4, 2003 until the principal hereof is due.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Euro Securities, and it shall pay interest on overdue installments of
interest at the same rate to the extent lawful.

2.   Method of Payment

         The Company shall pay interest on the Euro Securities (except defaulted
interest) to the Persons who are registered Holders at the close of business on
the May 1 or November 1 next preceding the interest payment date even if Euro
Securities are canceled after the record date and on or before the interest
payment date (whether or not a Business Day). The Holders must surrender Euro
Securities to a Paying Agent to collect principal payments. The Company shall
pay principal, premium, if any, and interest in money of a member state of the
European Union that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of the Euro Securities represented by a
Global Euro Security (including principal, premium and interest) shall be made
by wire transfer of immediately available funds to the accounts specified by The
Depository Trust Company or any successor depositary. The Company will make all
payments in respect of a certificated Euro Security (including principal,
premium, if any, and interest), at the office of a Paying Agent, except that, at
the option of the Company, payment of interest may be made by mailing a check to
the registered address of each Holder thereof; provided, however, that payments
on the Euro Securities may also be made, in the case of a Holder of at least
(Euro)1,000,000 aggregate principal amount of Euro Securities, by wire transfer
to a Euro account maintained by the payee with a bank in a member state of the
European Union if such Holder elects payment by wire transfer by giving written
notice to the Trustee or a Paying Agent to such effect designating such account
no later than 30 days immediately preceding the relevant due date for payment
(or such other date as the Trustee may accept in its discretion).

3.   Paying Agent and Registrar

         Initially, The Bank of New York, London Branch, will act as Euro Paying
Agent and Registrar. The Company may appoint and change any Paying Agent or
Registrar without notice. The Company or any of its domestically incorporated
Wholly Owned Subsidiaries may act as Paying Agent or Registrar.

                                      -4-

4.   Indenture

         The Company issued the Securities under an Indenture dated as of
November 4, 2003 (the "Indenture"), among the Company, the Guarantors and The
Bank of New York, a New York banking corporation (the "Trustee"). The terms of
the Euro Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss.
77aaa-77bbbb) as in effect on the date of the Indenture (the "TIA"). Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Euro Securities are subject to all terms and
provisions of the Indenture, and the Holders (as defined in the Indenture) are
referred to the Indenture and the TIA for a statement of such terms and
provisions.

         The Euro Securities are senior unsecured obligations of the Company.
This Euro Security is one of the Exchange Euro Securities referred to in the
Indenture. The Euro Securities include the Initial Euro Securities, the
Additional Euro Securities and any Exchange Euro Securities issued in exchange
for the Initial Euro Securities pursuant to the Indenture. The Initial Euro
Securities and Exchange Euro Securities together with the Initial Dollar
Securities and any Exchange Dollar Securities are treated as a single class of
securities under the Indenture. The Indenture imposes certain limitations on the
ability of Holdings, and its Restricted Subsidiaries to, among other things,
make certain Investments and other Restricted Payments, pay dividends and other
distributions, incur Indebtedness, enter into consensual restrictions upon the
payment of certain dividends and distributions by such Restricted Subsidiaries,
issue or sell shares of capital stock of Holdings, and such Restricted
Subsidiaries, enter into or permit certain transactions with Affiliates, create
or incur Liens and make asset sales. The Indenture also imposes limitations on
the ability of the Company and each Guarantor to consolidate or merge with or
into any other Person or convey, transfer or lease all or substantially all of
its property.

         To guarantee the due and punctual payment of the principal and
interest, if any, on the Euro Securities and all other amounts payable by the
Company under the Indenture and the Securities when and as the same shall be due
and payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Euro Securities and the Indenture, the Guarantors have, jointly and
severally, unconditionally guaranteed the Guaranteed Obligations on a senior
basis pursuant to the terms of the Indenture.

5.   Optional Redemption

         Except as set forth in the following two paragraphs, the Euro
Securities shall not be redeemable at the option of the Company prior to
November 15, 2007. Thereafter, the Euro Securities shall be redeemable at the
option of the Company, in whole at any time or in part from time to time, upon
on not less than 30 nor more than 60 days' prior notice, at the following
redemption prices (expressed as a percentage of principal amount), plus accrued
and unpaid interest to the redemption date (subject to the right of the Holders
of record on the relevant record date to receive interest due on the relevant
interest payment date), if redeemed during the 12-month period commencing on
November 15 of the years set forth below:

                                      -5-

                  YEAR                                 REDEMPTION PRICE
                  ----                                 ----------------
                  2007                                     103.875%
                  2008                                     101.938%
                  2009 and thereafter                      100.000%

         In addition, prior to November 15, 2007, the Company may redeem the
Euro Securities, at its option, in whole at any time or in part from time to
time, upon not less than 30 nor more than 60 days' prior notice mailed by
first-class mail to each Holder's registered address, at a redemption price
equal to 100% of the principal amount of the Euro Securities redeemed plus the
Applicable Premium as of, and accrued and unpaid interest to, the applicable
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

         Notwithstanding the foregoing, at any time and from time to time on or
prior to November 15, 2006, the Company may redeem in the aggregate up to 35% of
the original aggregate principal amount of the Euro Securities (calculated after
giving effect to any issuance of Additional Euro Securities), with the net cash
proceeds of one or more Equity Offerings (1) by the Company or (2) by Holdings
or any direct or indirect parent of Holdings or the Company, in each case, to
the extent the net cash proceeds thereof are contributed to the common equity
capital of the Company or used to purchase Capital Stock (other than
Disqualified Stock) of the Company from it, at a redemption price equal to
107.75% of the principal amount thereof, plus accrued and unpaid interest to the
redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that at least 65% of the original aggregate principal amount
of the Euro Securities (calculated after giving effect to any issuance of
Additional Euro Securities) must remain outstanding after each such redemption;
and provided, further, that such redemption shall occur within 90 days after the
date on which any such Equity Offering is consummated upon not less than 30 nor
more than 60 days' notice mailed to each Holder of Securities being redeemed and
otherwise in accordance with the procedures set forth in the Indenture.

6.   Sinking Fund

         The Euro Securities are not subject to any sinking fund.

7.   Notice of Redemption

         Notice of redemption will be mailed by first-class mail at least 30
days but not more than 60 days before the redemption date to each Holder of Euro
Securities to be redeemed at his, her or its registered address. Securities in
denominations larger than (Euro)1,000 may be redeemed in part but only in whole
multiples of (Euro)1,000. If money sufficient to pay the redemption price of and
accrued and unpaid interest on all Euro Securities (or portions thereof) to be
redeemed on the redemption date is deposited with a Paying Agent on or before
the redemption date and certain other conditions are satisfied, on and after
such date interest ceases to accrue on such Euro Securities (or such portions
thereof) called for redemption.

                                      -6-

8.   Repurchase of Euro Securities at the Option of the Holders
     upon Change of Control and Asset Sales

         Upon the occurrence of a Change of Control, each Holder shall have the
right, subject to certain conditions specified in the Indenture, to cause the
Company to repurchase all or any part of such Holder's Securities at a purchase
price in cash equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the date of repurchase (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant interest payment date), as provided in, and subject to the terms of,
the Indenture.

         In accordance with Section 4.06 of the Indenture, the Company will be
required to offer to purchase Euro Securities upon the occurrence of certain
events.

9.   Denominations; Transfer; Exchange

         The Euro Securities are in registered form, without coupons, in
denominations of (Euro)1,000 and whole multiples of (Euro)1,000. A Holder shall
register the transfer of or exchange of Euro Securities in accordance with the
Indenture. Upon any registration of transfer or exchange, the Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes required by law or
permitted by the Indenture. The Registrar need not register the transfer of or
exchange any Euro Securities selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Euro Security not to be
redeemed) or to transfer or exchange any Euro Securities for a period of 15 days
prior to a selection of Euro Securities to be redeemed.

10.  Persons Deemed Owners

         The registered Holder of this Euro Security shall be treated as the
owner of it for all purposes.

11.  Unclaimed Money

         If money for the payment of principal or interest remains unclaimed for
two years, the Trustee and a Paying Agent shall pay the money back to the
Company at its written request unless an abandoned property law designates
another Person. After any such payment, the Holders entitled to the money must
look to the Company for payment as general creditors and the Trustee and a
Paying Agent shall have no further liability with respect to such monies.

12.  Discharge and Defeasance

                  Subject to certain conditions, the Company at any time may
terminate some of or all its obligations under the Euro Securities and the
Indenture if the Company deposits with the Trustee money or EU Government
Obligations for the payment of principal and interest on the Securities to
redemption, or maturity, as the case may be.

                                      -7-

13.  Amendment, Waiver

         Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in aggregate principal amount of the outstanding
Securities (voting as a single class) and (ii) any past default or compliance
with any provisions may be waived with the written consent of the Holders of at
least a majority in principal amount of the outstanding Securities; provided,
however, that if any amendment, waiver or other modification will only affect
the Dollar Securities or the Euro Securities, only the consent of the Holders of
at least a majority in principal amount of the then outstanding Dollar
Securities or Euro Securities (and not the consent of the Holders of at least a
majority of all Securities), as the case may be, shall be required. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Holder, the Company and the Trustee may amend the Indenture or the Securities
(i) to cure any ambiguity, omission, defect or inconsistency; (ii) to comply
with Article 5 of the Indenture; (iii) to provide for uncertificated Securities
in addition to or in place of certificated Securities; (iv) to add Senior
Guarantees with respect to the Securities; (v) to add additional covenants of
the Company or Holdings for the benefit of the Holders or to surrender rights
and powers conferred on the Company; (vi) to comply with the requirements of the
SEC in order to effect or maintain the qualification of the Indenture under the
TIA; (vii) to make any change that does not adversely affect the rights of any
Holder; or (viii) to provide for the issuance of the Exchange Securities, or
Additional Securities.

14.  Defaults and Remedies

         If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of Holdings or the
Company) and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the outstanding Securities, in each case, by notice to the
Company, may declare the principal of, premium, if any, and accrued but unpaid
interest on all the Securities to be due and payable. If an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of
Holdings or the Company occurs, the principal of, premium, if any, and interest
on all the Securities shall become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders. Under
certain circumstances, the Holders of a majority in principal amount of the
outstanding Securities may rescind any such acceleration with respect to the
Securities and its consequences.

         If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense and certain other conditions are complied with. Except to
enforce the right to receive payment of principal, premium (if any) or interest
when due, no Holder may pursue any remedy with respect to the Indenture or the
Securities unless (i) such Holder has previously given the Trustee notice that
an Event of Default is continuing, (ii) the Holders of at least 25% in principal
amount of the outstanding Securities have requested the Trustee in writing to
pursue the remedy, (iii) such Holders have offered the Trustee reasonable
security or indemnity against any loss, liability or expense, (iv) the Trustee
has not complied with such request within 60 days after the receipt of the
request and the offer of

                                      -8-

security or indemnity and (v) the Holders of a majority in principal amount of
the outstanding Securities have not given the Trustee a direction inconsistent
with such request within such 60-day period. Subject to certain restrictions,
the Holders of a majority in principal amount of the outstanding Securities are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability. Prior to taking any action under the
Indenture, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion against all losses and expenses caused by taking or not
taking such action.

15.  Trustee Dealings with the Company

         Subject to certain limitations imposed by the TIA, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16.  No Recourse Against Others

         No director, officer, employee, incorporator or holder of any equity
interests in the Company (other than Holdings) or of any Guarantor or any direct
or indirect parent corporation, as such, shall have any liability for any
obligations of the Company or the Guarantors under the Securities, the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder of Securities by accepting a Security waives and
releases all such liability.

17.  Authentication

         This Euro Security shall not be valid until an authorized signatory of
the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Euro Security.

18.  Abbreviations

         Customary abbreviations may be used in the name of a Holder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

19.  Governing Law

         THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK.

20.  CUSIP Numbers, ISINs and Common Codes

         The Company has caused CUSIP numbers and ISINs and, in the case of the
Euro Securities, Common Codes, to be printed on the Securities and has directed
the Trustee to use CUSIP numbers and ISINs and, in the case of the Euro
Securities, Common Codes, in notices of redemption as a convenience to the
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Securities or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

         THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON WRITTEN
REQUEST AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH HAS IN IT
THE TEXT OF THIS SECURITY.

Nalco Company

c/o The Bank of New York
101 Barclay Street, Fl. 21 W
New York, New York  10286

Ladies and Gentlemen:

         This certificate is delivered to request a transfer of $/(Euro)[ ]
principal amount of the 7 3/4% Senior Notes due 2011 (the "Securities") of NALCO
COMPANY (the "Company").

         Upon transfer, the Securities would be registered in the name of the
new beneficial owner as follows:

Name:________________________

Address:_____________________

Taxpayer ID Number:__________

         The undersigned represents and warrants to you that:

         1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Securities, and we are acquiring the Securities not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Securities,
and we invest in or purchase securities similar to the Securities in the normal
course of our business. We, and any accounts for which we are acting, are each
able to bear the economic risk of our or its investment.

         2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor
account for which we are purchasing Securities to offer, sell or otherwise
transfer such Securities prior to the date that is two years after the later of
the date of original issue and the last date on which the Company or any
affiliate of the Company was the owner of such Securities (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to the Company,
(b) pursuant to a registration statement that has been declared effective under
the Securities Act, (c) in a transaction complying with the requirements of Rule
144A under the Securities Act ("Rule 144A"), to a person we reasonably believe
is a qualified institutional buyer under Rule 144A (a "QIB") that is

purchasing for its own account or for the account of a QIB and to whom notice is
given that the transfer is being made in reliance on Rule 144A, (d) pursuant to
offers and sales that occur outside the United States within the meaning of
Regulation S under the Securities Act, (e) to an institutional "accredited
investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act that is purchasing for its own account or for the account of such
an institutional "accredited investor," in each case in a minimum principal
amount of Securities of $250,000, or (f) pursuant to any other available
exemption from the registration requirements of the Securities Act, subject in
each of the foregoing cases to any requirement of law that the disposition of
our property or the property of such investor account or accounts be at all
times within our or their control and in compliance with any applicable state
securities laws. The foregoing restrictions on resale will not apply subsequent
to the Resale Restriction Termination Date. If any resale or other transfer of
the Securities is proposed to be made pursuant to clause (e) above prior to the
Resale Restriction Termination Date, the transferor shall deliver a letter from
the transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act and that it is acquiring such Securities for
investment purposes and not for distribution in violation of the Securities Act.
Each purchaser acknowledges that the Company and the Trustee reserve the right
prior to the offer, sale or other transfer prior to the Resale Restriction
Termination Date of the Securities pursuant to clause (d), (e) or (f) above to
require the delivery of an opinion of counsel, certifications or other
information satisfactory to the Company and the Trustee.

Dated:                                 TRANSFEREE:                             ,
