     in future periods); plus

cash, between a willing seller and a willing and able buyer, neither of whom is
under undue pressure or compulsion to complete the transaction.

         "Fixed Charge Coverage Ratio" means, with respect to any Person for any
period, the ratio of EBITDA of such Person for such period to the Fixed Charges
of such Person for such period. In the event that Holdings or any of its
Restricted Subsidiaries Incurs or redeems any Indebtedness (other than in the
case of revolving credit borrowings or revolving advances under any Qualified
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
prior to the event for which the calculation of the Fixed Charge Coverage Ratio
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

                                      -13-

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 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 Unaudited Pro Forma
Statements of Operations" under "Unaudited Pro Forma Financial Information" in
the Offering Memorandum, to the extent such adjustments, without duplication,
continue to be applicable to such four-quarter period.

     of the Appendix in which any such Global Security may be exchanged in whole
     or in part for Additional Securities registered, or any transfer of such
     Global Security in whole or in part may be registered, in the name or names
     of Persons other than the depositary for such Global Security or a nominee
     thereof; and

         (5) if applicable, that such Additional Securities that are not

     Securities as set forth in Exhibit A or B, but shall be issued in the form

         If any of the terms of any Additional Securities are established by
action taken pursuant to a resolution of the Board of Directors, a copy of an
appropriate record of such action shall be certified by the Secretary or any
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Officers' Certificate or the indenture supplemental hereto

         SECTION 2.02. Form and Dating. Provisions relating to the Initial
Securities and the Exchange Securities are set forth in the Appendix, which is
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

notation, legend or endorsement is in a form acceptable to the 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

         SECTION 2.03. Execution and Authentication. The Trustee shall

signed by one Officer (a) (i) Original Dollar Securities for original issue on
the date hereof in an aggregate principal amount of $465,000,000 and (ii)

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

                                      -36-

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.

         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

                                      -37-

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, 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.

                                      -38-

         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 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

                                      -39-

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 13.06, 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.

         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

                                      -40-

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 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 13.06 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

                                      -41-

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 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.

                                      -42-

         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 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

                                      -43-

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 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),

                                      -44-

         (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

         (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,

                                      -45-

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 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 Subordinated
     Guarantees, as applicable, (B) the Exchange Securities issued in exchange
     for the Original Securities and the Senior Subordinated Guarantees thereof,
     and (C) the Senior Notes and the related guarantees, as applicable;

                                      -46-

         (iii) Indebtedness existing on the Issue Date (other than Indebtedness
     described in clauses (i) and (ii) of this Section 4.03(b));

         (iv) Indebtedness (including Capitalized Lease Obligations) Incurred by
     Holdings or any of its Restricted Subsidiaries to finance the purchase,
     lease or improvement of property (real or personal) or 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 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 letters
     of credit issued in the ordinary course of business, including, without
     limitation, letters of credit in respect of workers' 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 Subordinated 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 Subsidiary) shall be deemed, in each case,
     to be an issuance of shares of Preferred Stock;

         (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 to a Restricted Subsidiary that is not a Guarantor such
     Indebtedness is subordinated in right of payment to the Senior

                                      -47-

     Subordinated 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;

         (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 purpose of fixing or hedging
     commodity price risk with respect to any commodity purchases;

         (xi) obligations in respect of performance, bid and surety bonds and
     completion guarantees provided by Holdings or any Restricted Subsidiary in
     the ordinary course of business;

         (xii) Indebtedness or Disqualified Stock of Holdings or any Restricted
     Subsidiary of Holdings not otherwise permitted hereunder in an aggregate
     principal amount which, when aggregated with the principal 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

     provided that if such Indebtedness is by its express terms subordinated in
     right of payment to the Securities or the Senior Subordinated Guarantee of

     Guarantor with respect to such Indebtedness shall be subordinated in right
     of payment to such Guarantor's Senior Subordinated Guarantee with respect

     refund or refinance such Indebtedness (subject to the following proviso,

                                      -48-

                  (1) has a Weighted Average Life to Maturity at the time such

         additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
         test set forth in Section 4.03(a); 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

         (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
Subordinated 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

of additional Indebtedness with the same terms, the payment of dividends on
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:

     or distribution in accordance with its Equity Interests in such class or
     series of securities);

     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

     company to pay federal, state or local income taxes (as the case may be)
     imposed directly on such parent company to the extent such income taxes are
     attributable to the income of Holdings and its Restricted Subsidiaries
     (including, without limitation, by virtue of such parent company being the
     common parent of a consolidated or combined tax group of which Holdings
     and/or its Restricted Subsidiaries are members); provided, however, that in
     each case the amount of such payments in respect of any tax year does not
     exceed the amount that Holdings and its Restricted Subsidiaries would have
     been required to pay in respect of federal, state or local taxes (as the
     case may be) in respect of such year if Holdings and its Restricted
     Subsidiaries paid such taxes directly as a stand-alone taxpayer (or
     stand-alone group);

         (xiii) the payment of dividends, other distributions or other amounts
     by Holdings or the Company, if applicable:

         expenses (including franchise or similar taxes) required to maintain
         its corporate existence, customary salary, bonus and other benefits
         payable to officers and employees of any direct parent of Holdings or
         the Company, if applicable, and general corporate overhead expenses of
         any direct parent of Holdings or the Company, if applicable, in each
         case to the extent such fees and expenses are attributable to the
         ownership or operation of Holdings or the Company, if applicable, and
         their respective Subsidiaries; and

                  (B) dividends paid to any direct parent of Holdings or the
         Company, if applicable, in amounts equal to amounts required for any
         direct parent of Holdings or the Company, if applicable, to pay
         interest and/or principal on Indebtedness the proceeds of which have
         been contributed to Holdings or any of its Restricted Subsidiaries and
         that has been guaranteed by, or is otherwise considered Indebtedness
         of, Holdings Incurred in accordance with Section 4.03;

         (xiv) cash dividends or other distributions on Holdings' Capital Stock
     used to, or the making of loans to any direct or indirect parent of
     Holdings to, fund the payment of fees and expenses incurred in connection
     with the Transactions or owed by Holdings, the Company or any direct or
     indirect parent company of Holdings or the Company, as the

                                      -56-

     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 exercise of
     stock options if such Equity Interests represent a portion of the exercise
     price of such options;

         (xvi) purchases of receivables pursuant to a Receivables Repurchase
     Obligation in connection with a Qualified Receivables Financing;

         (xvii) the repurchase, redemption or other acquisition or retirement
     for value of any Subordinated Indebtedness pursuant to provisions similar
     to those described under Sections 4.06 and 4.08; provided that all
     Securities tendered by Holders in connection with a Change of Control Offer
     or Asset Sale Offer, as applicable, have been repurchased, redeemed or
     acquired for value; and

         (xviii) any payments made in connection with the consummation 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
Restricted Payment permitted under clauses (vi), (vii), (x), (xi) and (xvii) of
this Section 4.04(b), no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof.

         (c) As of the Issue Date, all of Holdings' Subsidiaries shall be
Restricted Subsidiaries. Holdings shall not permit any Unrestricted Subsidiary
to become a Restricted 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

                                      -57-

         (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 Notes and the indenture
     relating to the Senior 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 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;

                                      -58-

         (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 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:

                                      -59-

         (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 Senior Indebtedness, including the Senior
     Notes, or Pari Passu Indebtedness (provided that if the Company or any
     Guarantor shall so reduce Obligations under 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), 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; provided, however, prior to commencing an Asset Sale Offer
under this Indenture, the Company shall first comply with its "Asset Sale Offer"
obligations with respect to the indenture governing the Senior Notes in
accordance with the terms thereof as in effect on the Issue Date and any Net
Proceeds applied thereunder to repurchase Senior Notes shall cease to constitute
Excess Proceeds under this Indenture. 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

                                      -60-

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 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.

                                      -61-

         (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:

         (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

                                      -62-

     (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);

         (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

     including fees to the Sponsors, which are described in the Offering
     Memorandum;

                                      -63-

     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

         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 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 or other Senior Indebtedness,
including the Senior Notes, 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 and such Senior Indebtedness, or (ii) obtain the requisite consent,
if required, under the agreements governing the Bank Indebtedness and such
Senior 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;

                                      -64-

         (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 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

                                      -65-

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.

         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
     Subordinated 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 Subordinated 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 Subordinated Guarantee if the Lien consists of a
     Permitted Lien.

         SECTION 4.13. Limitation on Other Senior Subordinated Indebtedness. The
Company shall not, and shall not permit any Guarantor to, directly or
indirectly, Incur any Indebtedness (including Acquired Indebtedness) that is
subordinate in right of payment to any Indebtedness of the Company or any
Indebtedness of any such Guarantor, as the case may be, unless such Indebtedness
is either:

                                      -66-

         (i) pari passu in right of payment with the Securities or such
     Guarantor's Senior Subordinated Guarantee, as the case may be, or

         (ii) subordinate in right of payment to the Securities or such
     Guarantor's Senior Subordinated Guarantee, as the case may be.

         SECTION 4.14. 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 demands may be made
or served at the corporate trust office of the Trustee as set forth in Section
13.02.

         (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.

         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

                                      -67-

     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;

         (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 Subordinated 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 11.02(b) (which govern the
release of a Senior Subordinated 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

                                      -68-

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
     Guarantors' Senior Subordinated 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 Subordinated
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, whether or not such payment shall be
     prohibited by Article 10, 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,
     whether or not such payment shall be prohibited by Article 10,

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

         (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, 4.12 and 4.13 (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,

                                      -70-

         (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,

         (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 Subordinated Guarantee of Holdings or any Senior
     Subordinated 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 Subordinated 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.

                                      -71-

         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;
provided, however, that so long as any Bank Indebtedness remains outstanding, no
such acceleration shall be effective until the earlier of (1) five (5) Business
Days after the giving of written notice to the Company and the Representative
under the Credit Agreement and (2) the day on which any Bank Indebtedness is
accelerated. 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 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

                                      -72-

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 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

                                      -73-

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 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 of Senior Indebtedness of the Company to the extent
     required by Article 10 and to holders of Senior Indebtedness of the
     Guarantors to the extent required by Article 12;

         THIRD: to the 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

         FOURTH: 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

                                      -74-

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.

                                    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

                                      -75-

         (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.

         (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.

                                      -76-

         (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.

         (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 Subordinated 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 13.02 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.

                                      -77-

         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. 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 Company. 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;

                                      -78-

         (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.

                                      -79-

         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;

                                      -80-

         (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, 4.12 and 4.13 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 Subordinated 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 be sufficient, or a
     combination thereof sufficient, to pay the principal of, and premium (if
     any) and interest

                                      -81-

     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 and is not prohibited by Article 10;

         (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.

         (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.

                                      -82-

         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. Money and securities so held in trust are
not subject to Article 10 or 12.

         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.

                                   ARTICLE 9

                             AMENDMENTS AND WAIVERS

         SECTION 9.01. Without Consent of the Holders. (a) 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;

                                      -83-

         (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 make any change in Article 10 or Article 12 that would limit or
     terminate the benefits available to any holder of Senior Indebtedness of
     the Company or a Guarantor (or Representatives thereof) under Article 10 or
     Article 12, respectively;

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

         (vi) 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;

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

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

         (ix) 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.

         (b) An amendment under this Section 9.01 may not make any change that
adversely affects the rights under Article 10 or Article 12 of any holder of
Senior Indebtedness of the Company or a Guarantor then outstanding unless the
holders of such Senior Indebtedness (or any group or Representative thereof
authorized to give a consent) consent to such change.

         After an amendment under this Section 9.01 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 9.01.

         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
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

                                      -84-

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 Article 10 or Article 12 that adversely affects
     the rights of any Holder under Article 10 or Article 12,

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

         (viii) modify the Senior Subordinated 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.

         An amendment under this Section 9.02 may not make any change that
adversely affects the rights under Article 10 or Article 12 of any holder of
Senior Indebtedness then outstanding unless the holders of such Senior
Indebtedness (or any group or Representative thereof authorized to give a
consent) consent to such change.

         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

                                      -85-

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 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.

                                      -86-

         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

                                  SUBORDINATION

         SECTION 10.01. Agreement to Subordinate. The Company agrees, and each
Holder by accepting a Security agrees, that the Indebtedness evidenced by the
Securities is subordinated in right of payment, to the extent and in the manner
provided in this Article 10, to the prior payment in full of all existing and
future Senior Indebtedness of the Company and that the subordination is for the
benefit of and enforceable by the holders of such Senior Indebtedness. The
Securities shall in all respects rank pari passu in right of payment with all
existing and future Pari Passu Indebtedness of the Company and shall rank senior
in right of payment to all existing and future Subordinated Indebtedness of the
Company; and only Indebtedness of the Company that is Senior Indebtedness of the
Company shall rank senior to the Securities in accordance with the provisions
set forth herein. For purposes of this Article 10, the Indebtedness evidenced by
the Securities shall be deemed to include any Registration Default Damages
payable pursuant to the provisions set forth in the Securities and the
Registration Agreement. All provisions of this Article 10 shall be subject to
Section 10.12.

         SECTION 10.02. Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of the Company to creditors upon a total or
partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

         (a) holders of Senior Indebtedness of the Company shall be entitled to
     receive payment in full in cash of such Senior Indebtedness (including
     interest accruing after, or which would accrue but for, the commencement of
     any such proceeding at the rate specified in the applicable Senior
     Indebtedness, whether or not a claim for such interest would be allowed)
     before Holders shall be entitled to receive any payment of principal of or
     interest on the Securities; and

         (b) until the Senior Indebtedness of the Company is paid in full in
     cash, any payment or distribution to which Holders would be entitled but
     for this Article 10 shall be made to holders of such Senior Indebtedness as
     their interests may appear, except that the Holders may receive and retain
     Permitted Junior Securities.

         SECTION 10.03. Default on Designated Senior Indebtedness. The Company
may not pay principal of, premium (if any) or interest on, the Securities or
make any deposit pursuant to the provisions described under Section 8.01 and may
not otherwise purchase, redeem or otherwise retire any Securities (except that
the Holders may receive and retain (a) Permitted

                                      -87-

Junior Securities and (b) payments made from the trust described under Article
8) (collectively, "pay the Securities") if:

         (1) a default in the payment of the principal of, premium, if any, or
     interest on any Designated Senior Indebtedness of the Company occurs and is
     continuing or any other amount owing in respect of any Designated Senior
     Indebtedness of the Company is not paid when due, or

         (2) any other default on Designated Senior Indebtedness of the Company
     occurs and the maturity of such Designated Senior Indebtedness of the
     Company is accelerated in accordance with its terms,

unless, in either case, the default has been cured or waived and any such
acceleration has been rescinded or such Designated Senior Indebtedness has been
paid in full in cash; provided, however, the Company may pay the Securities
without regard to the foregoing if the Company and the Trustee receive written
notice approving such payment from the Representative of the holders of such
Designated Senior Indebtedness with respect to which either of the events set
forth in clause (1) or (2) of this sentence has occurred and is continuing.
During the continuance of any default (other than a default described in clause
(1) or (2) of the preceding sentence) with respect to any Designated Senior
Indebtedness of the Company pursuant to which the maturity thereof may be
accelerated immediately without further notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, the Company may not pay the Securities for a period (a "Payment
Blockage Period") commencing upon the receipt by the Trustee (with a copy to the
Company) of written notice (a "Blockage Notice") of such default from the
Representative of the holders of such Designated Senior Indebtedness specifying
an election to effect a Payment Blockage Period and ending 179 days thereafter
(or earlier if such Payment Blockage Period is terminated (i) by written notice
to the Trustee and the Company from the Person or Persons who gave such Blockage
Notice; (ii) by repayment in full in cash of such Designated Senior
Indebtedness; or (iii) because the default giving rise to such Blockage Notice
is no longer continuing). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the
first sentence of this Section 10.03 and in Section 10.02(b)), unless the
holders of such Designated Senior Indebtedness or the Representative of such
holders shall have accelerated the maturity of such Designated Senior
Indebtedness or a payment default exists, the Company may resume payments on the
Securities after the end of such Payment Blockage Period. Not more than one
Blockage Notice may be given in any consecutive 360-day period, irrespective of
the number of defaults with respect to Designated Senior Indebtedness during
such period. In no event, however, may the total number of days during which any
Payment Blockage Period is in effect exceed 179 days in the aggregate during any
360 consecutive day period. For purposes of this Section 10.03, no default or
event of default that existed or was continuing on the date of the commencement
of any Payment Blockage Period with respect to the Designated Senior
Indebtedness initiating such Payment Blockage Period shall be, or be made, the
basis of the commencement of a subsequent Payment Blockage Period by the
Representative of such Designated Senior Indebtedness, whether or not within a
period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days (it
being understood that any subsequent action or any breach of any financial
covenants for a period commencing after the date of commencement of such Payment
Blockage

                                      -88-

Period that, in either case, would give rise to an event of default pursuant to
any provision of the Designated Senior Indebtedness under which an event of
default previously existed or was continuing shall constitute a new event of
default for this purpose).

         SECTION 10.04. Acceleration of Payment of Securities. If payment of the
Securities is accelerated because of an Event of Default, the Company or the
Trustee (provided, that the Trustee shall have received written notice from the
Company, on which notice the Trustee shall be entitled to conclusively rely)
shall promptly notify the holders of the Designated Senior Indebtedness of the
Company (or their Representative) of the acceleration.

         SECTION 10.05. When Distribution Must Be Paid Over. If a distribution
is made to the Holders that because of this Article 10 should not have been made
to them, the Holders who receive the distribution shall hold it in trust for
holders of Senior Indebtedness of the Company and pay it over to them as their
interests may appear.

         SECTION 10.06. Subrogation. After all Senior Indebtedness of the
Company is paid in full and until the Securities are paid in full, the Holders
shall be subrogated to the rights of holders of such Senior Indebtedness to
receive distributions applicable to Senior Indebtedness of the Company. A
distribution made under this Article 10 to holders of such Senior Indebtedness
which otherwise would have been made to the Holders is not, as between the
Company and the Holders, a payment by the Company on such Senior Indebtedness.

         SECTION 10.07. Relative Rights. This Article 10 defines the relative
rights of the Holders and holders of Senior Indebtedness of the Company. Nothing
in this Indenture shall:

         (a) impair, as between the Company and the Holders, the obligation of
     the Company, which is absolute and unconditional, to pay principal of and
     interest on the Securities in accordance with their terms; or

         (b) prevent the Trustee or any Holder from exercising its available
     remedies upon a Default, subject to the rights of holders of Senior
     Indebtedness of the Company to receive distributions otherwise payable to
     the Holders.

         SECTION 10.08. Subordination May Not Be Impaired by Company. No right
of any holder of Senior Indebtedness of the Company to enforce the subordination
of the Indebtedness evidenced by the Securities shall be impaired by any act or
failure to act by the Company or by its failure to comply with this Indenture.

         SECTION 10.09. Rights of Trustee and Paying Agent. Notwithstanding
Section 10.03, the Trustee or any Paying Agent may continue to make payments on
the Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 10. The Company, the Registrar, any Paying Agent, a Representative or a
holder of Senior Indebtedness of the Company may give the notice; provided,
however, that, if an issue of Senior Indebtedness of the Company has a
Representative, only the Representative may give the notice.

                                      -89-

         The Trustee in its individual or any other capacity may hold Senior
Indebtedness of the Company with the same rights it would have if it were not
Trustee. The Registrar and any Paying Agent may do the same with like rights.
The Trustee shall be entitled to all the rights set forth in this Article 10
with respect to any Senior Indebtedness of the Company which may at any time be
held by it, to the same extent as any other holder of such Senior Indebtedness;
and nothing in Article 7 shall deprive the Trustee of any of its rights as such
holder. Nothing in this Article 10 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07 or any other Section of this
Indenture.

         SECTION 10.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness
of the Company, the distribution may be made and the notice given to their
Representative (if any).

         SECTION 10.11. Article 10 Not to Prevent Events of Default or Limit
Right To Accelerate. The failure to make a payment pursuant to the Securities by
reason of any provision in this Article 10 shall not be construed as preventing
the occurrence of a Default. Nothing in this Article 10 shall have any effect on
the right of the Holders or the Trustee to accelerate the maturity of the
Securities.

         SECTION 10.12. Trust Monies Not Subordinated. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of
Government Obligations held in trust under Article 8 by the Trustee and
deposited at a time when permitted by the subordination provisions of this
Article 10 for the payment of principal of and interest on the Securities shall
not be subordinated to the prior payment of any Senior Indebtedness of the
Company or subject to the restrictions set forth in this Article 10, and none of
the Holders shall be obligated to pay over any such amount to the Company or any
holder of Senior Indebtedness of the Company or any other creditor of the
Company.

         SECTION 10.13. Trustee Entitled to Rely. Upon any payment or
distribution pursuant to this Article 10, the Trustee and the Holders shall be
entitled to rely (a) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.02
are pending, (b) upon a certificate of the liquidating trustee or agent or other
Person making such payment or distribution to the Trustee or to the Holders or
(c) upon the Representatives for the holders of Senior Indebtedness of the
Company for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of such Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article 10. In the event that the Trustee determines, in good faith,
that evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness of the Company to participate in any payment or distribution
pursuant to this Article 10, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of such
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and other facts
pertinent to the rights of such Person under this Article 10, and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all
actions or omissions of actions by the Trustee pursuant to this Article 10.

                                      -90-

         SECTION 10.14. Trustee to Effectuate Subordination. Each Holder by
accepting a Security authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination between the Holders and the holders of Senior Indebtedness of the
Company as provided in this Article 10 and appoints the Trustee as
attorney-in-fact for any and all such purposes.

         SECTION 10.15. Trustee Not Fiduciary for Holders of Senior
Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of the Company and shall not be liable to any
such holders if it shall mistakenly pay over or distribute to the Holders or the
Company or any other Person money or assets to which any holders of Senior
Indebtedness of the Company shall be entitled by virtue of this Article 10 or
otherwise.

         SECTION 10.16. Reliance by Holders of Senior Indebtedness on
Subordination Provisions. Each Holder by accepting a Security acknowledges and
agrees that the foregoing subordination provisions are, and are intended to be,
an inducement and a consideration to each holder of any Senior Indebtedness of
the Company, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Securities, to acquire and continue to hold, or to
continue to hold, such Senior Indebtedness and such holder of such Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Indebtedness.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Trustee or the Holders and without impairing or
releasing the subordination provided in this Article 10 or the obligations
hereunder of the Holders to the holders of the Senior Indebtedness of the
Company, do any one or more of the following: (i) change the manner, place or
terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness of the Company, or otherwise amend or supplement in any manner
Senior Indebtedness of the Company, or any instrument evidencing the same or any
agreement under which Senior Indebtedness of the Company is outstanding; (ii)
sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing Senior Indebtedness of the Company; (iii) release any
Person liable in any manner for the payment or collection of Senior Indebtedness
of the Company; and (iv) exercise or refrain from exercising any rights against
the Company and any other Person.

                                   ARTICLE 11

                         SENIOR SUBORDINATED GUARANTEES

         SECTION 11.01. Senior Subordinated 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

                                      -91-

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 11 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 11.02(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 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 Subordinated
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) The Senior Subordinated Guarantee of each Guarantor is, to the
extent and in the manner set forth in Article 12, subordinated and subject in
right of payment to the prior payment in full of the principal of and premium,
if any, and interest on all Senior Indebtedness of the relevant Guarantor and is
made subject to such provisions of this Indenture.

         (f) Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06,
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

                                      -92-

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.

         (g) Each Guarantor agrees that its Senior Subordinated Guarantee shall
remain in full force and effect until payment in full of all the Guaranteed
Obligations. Each Guarantor further agrees that its Senior Subordinated
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.

         (h) 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.

         (i) 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 and all
obligations to which the Guaranteed Obligations are subordinated as provided in
Article 12. Each Guarantor further agrees 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 Subordinated 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 11.01.

         (j) 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 11.01.

                                      -93-

         (k) 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 11.02. 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 Subordinated 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
11 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

         (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 Subordinated 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 11.03. Successors and Assigns. This Article 11 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

                                      -94-

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 11.04. 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 11 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 11 at law,
in equity, by statute or otherwise.

         SECTION 11.05. Modification. No modification, amendment or waiver of
any provision of this Article 11, 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 11.06. 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 11 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 proceeding at law or in
equity, the Senior Subordinated 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 11.07. Non-Impairment. The failure to endorse a Senior
Subordinated Guarantee on any Security shall not affect or impair the validity
thereof.

                                   ARTICLE 12

               SUBORDINATION OF THE SENIOR SUBORDINATED GUARANTEES

         SECTION 12.01. Agreement to Subordinate. Each Guarantor agrees, and
each Holder by accepting a Security agrees, that the obligations of a Guarantor
hereunder are subordinated in right of payment, to the extent and in the manner
provided in this Article 12, to the prior payment in full of all existing and
future Senior Indebtedness of such Guarantor and that the subordination is for
the benefit of and enforceable by the holders of such Senior Indebtedness of
such Guarantor. The obligations hereunder with respect to a Guarantor shall in
all respects rank pari passu in right of payment with all existing and future
Pari Passu

                                      -95-

Indebtedness of such Guarantor and shall rank senior in right of payment to all
existing and future Subordinated Indebtedness of such Guarantor; and only
Indebtedness of such Guarantor that is Senior Indebtedness of such Guarantor
shall rank senior to the obligations of such Guarantor in accordance with the
provisions set forth herein. For purposes of this Article 12, the Indebtedness
evidenced by the Securities shall be deemed to include any Registration Default
Damages payable pursuant to the provisions set forth in the Securities and the
Registration Agreement. All provisions of this Article 12 shall be subject to
Section 12.16.

         SECTION 12.02. Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of a Guarantor to creditors upon a total or
partial liquidation or a total or partial dissolution of such Guarantor or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to such Guarantor and its properties:

         (a) holders of Senior Indebtedness of such Guarantor shall be entitled
     to receive payment in full in cash of such Senior Indebtedness (including
     interest accruing after, or which would accrue but for, the commencement of
     any such proceeding at the rate specified in the applicable Senior
     Indebtedness, whether or not a claim for such interest would be allowed)
     before the Holders shall be entitled to receive any payment pursuant to any
     Guaranteed Obligations from such Guarantor; and

         (b) until the Senior Indebtedness of such Guarantor is paid in full in
     cash, any payment or distribution to which the Holders would be entitled
     but for this Article 12 shall be made to holders of such Senior
     Indebtedness as their interests may appear, except that the Holders may
     receive and retain Permitted Junior Securities.

         SECTION 12.03. Default on Designated Senior Indebtedness of a
Guarantor. A Guarantor may not make any payment pursuant to any of the
Guaranteed Obligations or otherwise purchase, redeem or otherwise retire any
Securities (except that the Holders may receive and retain (a) Permitted Junior
Securities and (b) payments made from the trust described under Article 8
(collectively, "pay its Senior Subordinated Guarantee") if:

         (1) a default in the payment of the principal of, premium, if any, or
     interest on any Designated Senior Indebtedness of such Guarantor occurs and
     is continuing or any other amount owing in respect of any Designated Senior
     Indebtedness of such Guarantor is not paid when due, or

         (2) any other default on Designated Senior Indebtedness of such
     Guarantor occurs and the maturity of such Designated Senior Indebtedness of
     such Guarantor is accelerated in accordance with its terms,

unless, in either case, the default has been cured or waived and any such
acceleration has been rescinded or such Designated Senior Indebtedness has been
paid in full in cash; provided, however, such Guarantor may pay its Senior
Subordinated Guarantee without regard to the foregoing if such Guarantor and the
Trustee receive written notice approving such payment from the Representative of
the holders of such Designated Senior Indebtedness with respect to which either
of the events set forth in clause (1) or (2) of this sentence has occurred and
is continuing. During the continuance of any default (other than a default
described in clause (1) or (2) of the

                                      -96-

preceding sentence) with respect to any Designated Senior Indebtedness of a
Guarantor pursuant to which the maturity thereof may be accelerated immediately
without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, such Guarantor
may not pay its Senior Subordinated Guarantee for a period (a "Guarantee Payment
Blockage Period") commencing upon the receipt by the Trustee (with a copy to
such Guarantor and the Company) of written notice (a "Guarantee Blockage
Notice") of such default from the Representative of the holders of such
Designated Senior Indebtedness specifying an election to effect a Guarantee
Payment Blockage Period and ending 179 days thereafter (or earlier if such
Guarantee Payment Blockage Period is terminated (i) by written notice to the
Trustee, such Guarantor and the Company from the Person or Persons who gave such
Guarantee Blockage Notice; (ii) by repayment in full in cash of such Designated
Senior Indebtedness; or (iii) because the default giving rise to such Guarantee
Blockage Notice is no longer continuing). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this Section 12.03 and in Section 12.02(b)),
unless the holders of such Designated Senior Indebtedness or the Representative
of such holders shall have accelerated the maturity of such Designated Senior
Indebtedness or a payment default exists, such Guarantor may resume payments on
its Senior Subordinated Guarantee after the end of such Guarantee Payment
Blockage Period (including any missed payments). Not more than one Guarantee
Blockage Notice may be given with respect to a Guarantor in any consecutive
360-day period, irrespective of the number of defaults with respect to
Designated Senior Indebtedness during such period. In no event, however, may the
total number of days during which any Guarantee Payment Blockage Period is in
effect exceed 179 days in the aggregate during any 360 consecutive day period.
For purposes of this Section 12.03, no default or event of default that existed
or was continuing on the date of the commencement of any Guarantee Payment
Blockage Period with respect to the Designated Senior Indebtedness initiating
such Guarantee Payment Blockage Period shall be, or be made, the basis of the
commencement of a subsequent Guarantee Payment Blockage Period by the
Representative of such Designated Senior Indebtedness, whether or not within a
period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days (it
being understood that any subsequent action or any breach of any financial
covenants for a period commencing after the date of commencement of such
Guarantee Payment Blockage Period that, in either case, would give rise to an
event of default pursuant to any provision of the Designated Senior Indebtedness
under which an event of default previously existed or was continuing shall
constitute a new event of default for this purpose).

         SECTION 12.04. Demand for Payment. If payment of the Securities is
accelerated because of an Event of Default and a demand for payment is made on a
Guarantor pursuant to Article 11, the Company, the Guarantor or the Trustee
(provided that the Trustee shall have received written notice from the Company
or such Guarantor, on which notice the Trustee shall be entitled to conclusively
rely) shall promptly notify the holders of the Designated Senior Indebtedness of
such Guarantor (or the Representative of such holders) of such demand.

         SECTION 12.05. When Distribution Must Be Paid Over. If a payment or
distribution is made to the Holders that because of this Article 12 should not
have been made to them, the Holders who receive the payment or

                                      -97-

distribution shall hold such payment or distribution in trust for holders of the
Senior Indebtedness of the relevant Guarantor and pay it over to them as their
respective interests may appear.

         SECTION 12.06. Subrogation. After all Senior Indebtedness of a
Guarantor is paid in full and until the Securities are paid in full in cash, the
Holders shall be subrogated to the rights of holders of Senior Indebtedness of
such Guarantor to receive distributions applicable to Senior Indebtedness of
such Guarantor. A distribution made under this Article 12 to holders of Senior
Indebtedness of such Guarantor which otherwise would have been made to the
Holders is not, as between such Guarantor and the Holders, a payment by such
Guarantor on Senior Indebtedness of such Guarantor.

         SECTION 12.07. Relative Rights. This Article 12 defines the relative
rights of the Holders and holders of Senior Indebtedness of a Guarantor. Nothing
in this Indenture shall:

         (a) impair, as between a Guarantor and the Holders, the obligation of a
     Guarantor which is absolute and unconditional, to make payments with
     respect to the Guaranteed Obligations to the extent set forth in Article
     11; or

         (b) prevent the Trustee or any Holder from exercising its available
     remedies upon a default by a Guarantor under its obligations with respect
     to the Guaranteed Obligations, subject to the rights of holders of Senior
     Indebtedness of such Guarantor to receive distributions otherwise payable
     to the Holders.

         SECTION 12.08. Subordination May Not Be Impaired by a Guarantor. No
right of any holder of Senior Indebtedness of a Guarantor to enforce the
subordination of the obligations of such Guarantor hereunder shall be impaired
by any act or failure to act by such Guarantor or by its failure to comply with
this Indenture.

         SECTION 12.09. Rights of Trustee and Paying Agent. Notwithstanding
Section 12.03, the Trustee or any Paying Agent may continue to make payments on
the Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 12. A Guarantor, the Registrar or co-registrar, a Paying Agent, a
Representative or a holder of Senior Indebtedness of a Guarantor may give the
notice; provided, however, that if an issue of Senior Indebtedness of a
Guarantor has a Representative, only the Representative may give the notice.

         The Trustee in its individual or any other capacity may hold Senior
Indebtedness of a Guarantor with the same rights it would have if it were not
Trustee. The Registrar and co-registrar and any Paying Agent may do the same
with like rights. The Trustee shall be entitled to all the rights set forth in
this Article 12 with respect to any Senior Indebtedness of a Guarantor which may
at any time be held by it, to the same extent as any other holder of Senior
Indebtedness of such Guarantor; and nothing in Article 7 shall deprive the
Trustee of any of its rights as such holder. Nothing in this Article 12 shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
7.07 or any other Section of this Indenture.

                                      -98-

         SECTION 12.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness
of a Guarantor, the distribution may be made and the notice given to their
Representative (if any).

         SECTION 12.11. Article 12 Not to Prevent Events of Default or Limit
Right to Accelerate. The failure of a Guarantor to make a payment on any of its
obligations by reason of any provision in this Article 12 shall not be construed
as preventing the occurrence of a default by such Guarantor under such
obligations. Nothing in this Article 12 shall have any effect on the right of
the Holders or the Trustee to make a demand for payment on a Guarantor pursuant
to Article 11.

         SECTION 12.12. Trustee Entitled to Rely. Upon any payment or
distribution pursuant to this Article 12, the Trustee and the Holders shall be
entitled to rely (a) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 12.02
are pending, (b) upon a certificate of the liquidating trustee or agent or other
Person making such payment or distribution to the Trustee or to the Holders or
(c) upon the Representatives for the holders of Senior Indebtedness of a
Guarantor for the purpose of ascertaining the Persons entitled to participate in
such payment or distribution, the holders of the Senior Indebtedness of a
Guarantor and other Indebtedness of a Guarantor, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article 12. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness of a Guarantor to participate
in any payment or distribution pursuant to this Article 12, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness of such Guarantor held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and other facts pertinent to the rights of such Person
under this Article 12, and, if such evidence is not furnished, the Trustee may
defer any payment to such Person pending judicial determination as to the right
of such Person to receive such payment. The provisions of Sections 7.01 and 7.02
shall be applicable to all actions or omissions of actions by the Trustee
pursuant to this Article 12.

         SECTION 12.13. Trustee to Effectuate Subordination. Each Holder by
accepting a Security authorizes and directs the Trustee on his or her behalf to
take such action as may be necessary or appropriate to acknowledge or effectuate
the subordination between the Holders and the holders of Senior Indebtedness of
each of the Guarantors as provided in this Article 12 and appoints the Trustee
as attorney-in-fact for any and all such purposes.

         SECTION 12.14. Trustee Not Fiduciary for Holders of Senior Indebtedness
of a Guarantor. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of a Guarantor and shall not be liable to any
such holders if it shall mistakenly pay over or distribute to the Holders or the
relevant Guarantor or any other Person, money or assets to which any holders of
Senior Indebtedness of such Guarantor shall be entitled by virtue of this
Article 12 or otherwise.

         SECTION 12.15. Reliance by Holders of Senior Indebtedness of a
Guarantor on Subordination Provisions. Each Holder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a

                                      -99-

consideration to each holder of any Senior Indebtedness of a Guarantor, whether
such Senior Indebtedness was created or acquired before or after the issuance of
the Securities, to acquire and continue to hold, or to continue to hold, such
Senior Indebtedness and such holder of Senior Indebtedness shall be deemed
conclusively to have relied on such subordination provisions in acquiring and
continuing to hold, or in continuing to hold, such Senior Indebtedness.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of a Guarantor may, at any time and from time
to time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Trustee or the Holders and without impairing or
releasing the subordination provided in this Article 12 or the obligations
hereunder of the Holders to the holders of the Senior Indebtedness of a
Guarantor, do any one or more of the following: (i) change the manner, place or
terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness of a Guarantor, or otherwise amend or supplement in any manner
Senior Indebtedness of a Guarantor, or any instrument evidencing the same or any
agreement under which Senior Indebtedness of a Guarantor is outstanding; (ii)
sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing Senior Indebtedness of a Guarantor; (iii) release any
Person liable in any manner for the payment or collection of Senior Indebtedness
of a Guarantor; and (iv) exercise or refrain from exercising any rights against
such Guarantor and any other Person.

         SECTION 12.16. Trust Monies Not Subordinated. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of
Government Obligations held in trust under Article 8 by the Trustee and
deposited at a time when permitted by the subordination provisions of this
Article 12 for the payment of principal of and interest on the Securities shall
not be subordinated to the prior payment of any Senior Indebtedness of any
Guarantor or subject to the restrictions set forth in this Article 12, and none
of the Holders shall be obligated to pay over any such amount to a Guarantor or
any holder of Senior Indebtedness of a Guarantor or any other creditor of a
Guarantor.

                                  MISCELLANEOUS

         SECTION 13.01. Trust Indenture Act Controls. If and to the extent that
any provision of this Indenture limits, qualifies or conflicts with the duties
imposed by, or with another provision (an "incorporated provision") included in
this Indenture by operation of, Sections 310 to 318 of the TIA, inclusive, such
imposed duties or incorporated provision shall control.

                                     -100-

         SECTION 13.02. Notices. (a) Any notice or communication required or

                       if to the Company or a Guarantor:

                       1601 W. Diehl Road

                       The Bank of New York
                       101 Barclay Street, Fl. 21W

The Company or the Trustee by notice to the other may designate additional or
different addresses for subsequent notices or communications.

         (b) Any notice or communication mailed to a Holder shall be mailed,
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
published in English in a leading newspaper having general circulation in
Luxembourg (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 13.03. 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.

                                     -101-

         SECTION 13.04. 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 13.05. 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.

         SECTION 13.06. 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 13.07. 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 13.08. 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

                                     -102-

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 13.09. 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 13.10. 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 13.11. 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 13.12. 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 13.13. 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.

         SECTION 13.14. 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 13.15. 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 13.16. 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 Subordinated 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 Subordinated
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

                                     -103-

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 13.16(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 13.16, 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 13.16 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 Subordinated Guarantees and this Indenture:

         (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.

                                     -104-

         (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
     Subordinated 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 Subordinated 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 13.16 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 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.

                                     -105-

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

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
applicable, at the direction of the Trustee to reflect such increase.

         (h) Obligations with Respect to Transfers and Exchanges of Securities.

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
Security, the Company, the Trustee, a Paying Agent or 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
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) No Obligation of the Trustee.

         (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
the Depository or its nominee or of any participant or member thereof, with
respect to any ownership interest in the Securities or with respect to the
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). 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).

                                      A-5

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. 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 subordinated 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
subordinated basis pursuant to the terms of the Indenture.

5. Optional Redemption

         Except as set forth in the following two paragraphs, the Dollar

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

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:

                  YEAR                                 REDEMPTION PRICE
                  ----                                 ----------------

                  2008                                     104.438%
                  2009                                     102.958%
                  2010                                     101.479%
                  2011 and thereafter                      100.000%

         In addition, prior to November 15, 2008, 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
108.875% 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

                                      A-7

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.

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. Subordination

         The Dollar Securities and Senior Subordinated Guarantees are
subordinated to Senior Indebtedness, as defined in the Indenture. To the extent
provided in the Indenture, Senior Indebtedness must be paid before the
Securities and Senior Subordinated Guarantees may be paid. The Company and each
Guarantor agrees, and each Holder by accepting a Dollar Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

10. 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.

11. Persons Deemed Owners

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

12. 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

                                      A-8

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.

13. 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.

14. 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
Subordinated 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; (viii) to make any change in the subordination
provisions of the Indenture that would limit or terminate the benefits available
to any holder of Senior Indebtedness of the Company (or any Representative
thereof) under such subordination provisions; or (x) to provide for the issuance
of the Exchange Securities or Additional Securities.

15. 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

                                      A-9

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 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.

16. 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.

17. 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.

18. 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.

                                      A-10

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

Act).

20. Governing Law

21. CUSIP Numbers, ISINs and Common Codes

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

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. 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

                                      B-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.
(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 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 subordinated 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 subordinated
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, 2008. 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:

                                      B-6

                  YEAR                                 REDEMPTION PRICE
                  ----                                 ----------------

                  2008                                     104.500%
                  2009                                     103.000%
                  2010                                     101.500%
                  2011 and thereafter                      100.000%

         In addition, prior to November 15, 2008, 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
109.000% 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.

                                      B-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. Subordination

         The Euro Securities and Senior Subordinated Guarantees are subordinated
to Senior Indebtedness, as defined in the Indenture. To the extent provided in
the Indenture, Senior Indebtedness must be paid before the Euro Securities and
Senior Subordinated Guarantees may be paid. The Company and each Guarantor
agrees, and each Holder by accepting a Euro Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

10. 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.

11. Persons Deemed Owners

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

12. 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.

                                      B-8

13. 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.

14. 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
Subordinated 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; (viii) to make any change in the subordination
provisions of the Indenture that would limit or terminate the benefits available
to any holder of Senior Indebtedness of the Company (or any Representative
thereof) under such subordination provisions; or (ix) to provide for the
issuance of the Exchange Securities or Additional Securities.

15. 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.

                                      B-9

         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 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.

16. 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.

17. 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.

18. 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.

                                      B-10

19. 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).

20. Governing Law

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

21. 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.

                     8 7/8% Senior Subordinated Note due 2013

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.

                                      C-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. (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
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 subordinated 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 subordinated 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, 2008. 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:

                                      C-5

                  YEAR                                REDEMPTION PRICE
                  ----                                ----------------

                  2008                                    104.438%
                  2009                                    102.958%
                  2010                                    101.479%
                  2011 and thereafter                     100.000%

         In addition, prior to November 15, 2008, 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
108.875% 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.

                                      C-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. Subordination

         The Dollar Securities and Senior Subordinated Guarantees are
subordinated to Senior Indebtedness, as defined in the Indenture. To the extent
provided in the Indenture, Senior Indebtedness must be paid before the
Securities and Senior Subordinated Guarantees may be paid. The Company and each
Guarantor agrees, and each Holder by accepting a Dollar Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

10. 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 of 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.

11. Persons Deemed Owners

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

12. 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.

                                      C-7

13. 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.

14. 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
Subordinated 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; (viii) to make any change in the subordination
provisions of the Indenture that would limit or terminate the benefits available
to any holder of Senior Indebtedness of the Company (or any Representative
thereof) under such subordination provisions; or (ix) to provide for the
issuance of the Exchange Securities or Additional Securities.

15. 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.

                                      C-8

         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 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.

16. 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.

17. 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.

18. 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.

                                      C-9

19. 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).

20. Governing Law

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

21. 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

                [FORM OF REVERSE SIDE OF EXCHANGE EURO SECURITY]

                      9 % Senior Subordinated Note due 2013

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.

                                      D-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.
(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 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 subordinated 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 subordinated 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, 2008. 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:

                                      D-5

                  YEAR                                REDEMPTION PRICE
                  ----                                ----------------

                  2008                                    104.500%
                  2009                                    103.000%
                  2010                                    101.500%
                  2011 and thereafter                     100.000%

         In addition, prior to November 15, 2008, 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
109.000% 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.

                                      D-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 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. Subordination

         The Euro Securities and Senior Subordinated Guarantees are subordinated
to Senior Indebtedness, as defined in the Indenture. To the extent provided in
the Indenture, Senior Indebtedness must be paid before the Euro Securities and
Senior Subordinated Guarantees may be paid. The Company and each Guarantor
agrees, and each Holder by accepting a Euro Security agrees, to the
subordination provisions contained in the Indenture and authorizes the Trustee
to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

10. 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.

11. Persons Deemed Owners

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

12. 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.

                                      D-7

13. 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.

14. 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
Subordinated 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; (viii) to make any change in the subordination
provisions of the Indenture that would limit or terminate the benefits available
to any holder of Senior Indebtedness of the Company (or any Representative
thereof) under such subordination provisions; or (ix) to provide for the
issuance of the Exchange Securities or Additional Securities.

15. 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.

                                      D-8

         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 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.

16. 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.

17. 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.

18. 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.

                                      D-9

19. 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).

20. Governing Law

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

21. 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.

Ladies and Gentlemen:

         This certificate is delivered to request a transfer of $/(euro)[ ]
principal amount of the [8 7/8% Senior Subordinated Notes due 2013] [9% Senior
Subordinated Notes due 2013] (the "Securities") of NALCO COMPANY (the

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

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

                                      E-1

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.
