RESOLUTION 22

(Authorisation to be given to the Board of Directors for the purpose of issuing
shares and/or negotiable securities giving access to the share capital and
issued by the Company reserved for members of a company savings or other plan)

The General Meeting, deliberating under the quorum and majority conditions
required for extraordinary general meetings, having considered the report of the
Board of Directors and the special report of the Statutory Auditors, and in
accordance with the provisions of Articles L.225-129 and following and
L.225-138-1 of the Commercial Code, and Articles L.443-1 and following of the
Employment Code:

1. Authorises the Board of Directors on its sole initiative and on one or more
occasions to issue shares or negotiable securities giving access to the share
capital reserved for employees who are members of one of the company savings
plans (or of any other structure or entity authorised by the laws and
regulations) of the Company or companies connected with the Company within the
meaning of Article L.225-180 of the Commercial Code and Article L.444-3 of the
Employment Code.

2. Resolves to cancel the preferential subscription right of shareholders to
subscribe for the shares or negotiable securities which may be issued pursuant
to this authorisation, in favour of such members, and to waive any right to the
shares which may be allocated free of charge based on this resolution.

3. Resolves to limit the maximum nominal amount of the increase in share capital
which may be carried out pursuant to this authorisation to 30 million euros.

4. Resolves that the subscription price of the shares or negotiable securities
giving access to the share capital of the Company shall be fixed under the
conditions provided by the applicable laws and regulations.

5. Authorises the Board of Directors, pursuant to the provisions of Article
L.443-5 4th paragraph of the Employment Code, to allocate to subscribers free of
charge, shares to be issued or already issued or any other securities to be
issued or already issued which give access to the authorised share capital.

The Board of Directors may choose either to allocate these shares and securities
in whole or in part in place of the maximum discounts provided above in respect
of the fixing of the issue price, or to charge the equivalent value of these
shares and securities to the additional amount, or to combine the two
possibilities.

6. Resolves that this delegated power shall cancel that conferred by the 19th
resolution of the General Meeting of shareholders dated 31 March 2004.

This delegated power given to the Board of Directors is valid for a period of 26
months with effect from the date of this General Meeting.

The General Meeting confers all necessary powers on the Board of Directors, with
the power to delegate such powers under the conditions provided by law and by
the by-laws, to fix the terms and conditions of implementation of the increase
in the share capital decided on pursuant to this resolution, to determine the
beneficiaries, to record the completion of the increases in share capital, to
amend the by-laws and to carry out the required formalities.EX-4.2

in the case of revolving credit borrowings or revolving advances under any Qualified Receivables
Financing, in which case interest expense will be computed based upon the average daily balance of
such Indebtedness during the applicable period) or issues, repurchases or redeems preferred equity
subsequent to the commencement of the period for which the Fixed Charge Coverage Ratio is being
calculated and on or prior to the date on which the event for which the calculation of the Fixed
Charge Coverage Ratio is made (the “Calculation Date”), then the Fixed Charge Coverage Ratio will
be calculated giving pro forma effect to such incurrence, assumption, guarantee, repayment,
repurchase, redemption, defeasance or other discharge of Indebtedness, or such issuance, repurchase
or redemption of preferred equity, and the use of the proceeds therefrom, as if the same had
occurred at the beginning of the applicable four-quarter reference period.

          In addition, for purposes of calculating the Fixed Charge Coverage Ratio, Asset Acquisitions,
dispositions, mergers, consolidations and discontinued operations (as determined in accordance with
GAAP), and any related financing transactions, that the specified Person or any of its Restricted
Subsidiaries has both determined to make and made after the date of this Indenture 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 Asset Acquisitions, dispositions, mergers, consolidations and discontinued operations (and the
change of any associated Fixed Charges and the change in Consolidated Cash Flow resulting
therefrom) had occurred on the first day of the four-quarter reference period, including any pro
forma expense and cost reductions and other operating improvements that have occurred or are
reasonably expected to occur, in the reasonable judgment of the chief financial officer of the
Company (regardless of whether these cost savings or operating improvements could then be reflected
in pro forma financial statements in accordance with Regulation S-X promulgated under the
Securities Act or any other regulation or policy of the SEC related thereto). Any Person that is a
Restricted Subsidiary on the Calculation Date will be deemed to have been a Restricted Subsidiary
at all times during such four-quarter period, and if, since the beginning of the four-quarter
reference period, any Person that subsequently became a Restricted Subsidiary or was merged with or
into the Company or any of its other Restricted Subsidiaries since the beginning of such period
shall have made any acquisition, Investment, 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 adjusted
giving pro forma effect thereto for such period as if such Asset Acquisition, disposition,
discontinued operation, merger or consolidation had occurred at the beginning of the applicable
four-quarter reference period. Any Person that is not a Restricted Subsidiary on the Calculation
Date will be deemed not to have been a Restricted Subsidiary at any time during such 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

-13-

 

has a remaining term in excess of 12 months). Interest on a Capital 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 Capital 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 operating expense reductions reasonably expected to result from any
acquisition or merger.

          “Fixed Charges” means, with respect to any specified Person for any period, the sum, without
duplication, of:

     (1) the consolidated interest expense of such Person and its Restricted Subsidiaries
for such period, whether paid or accrued, excluding amortization of debt issuance costs and
the expensing of any bridge or other financing fees, but including original issue discount,
non-cash interest payments, the interest component of any deferred payment obligations
(classified as Indebtedness under this Indenture), the interest component of all payments
associated with Capital Lease Obligations and net of the effect of all payments made or
received pursuant to Hedging Obligations in respect of interest rates; plus

Notes shall be in denominations of $1,000 and integral multiples thereof.

          The terms and provisions contained in the Notes will constitute, and are hereby expressly
made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution
and delivery of this Indenture, expressly agree to such terms and provisions and to be bound
thereby. However, to the extent any provision of any Note conflicts with the express provisions of
this Indenture, the provisions of this Indenture shall govern and be controlling.

hereto (including the Global Note Legend thereon and the “Schedule of
Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form
will be substantially in the form of Exhibit A hereto (but without the Global Note
Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached
thereto). Each Global Note will represent such of the outstanding Notes as will be specified
therein and each shall provide that it represents the aggregate principal amount of outstanding
Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding
Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect
exchanges and

redemptions. Any endorsement of a Global Note to reflect the amount of any increase
or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made
by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions
given by the Holder thereof as required by Section 2.06 hereof.

Regulation S Global Notes pursuant to Section 2.06 and the Applicable Procedures. Simultaneously
with the authentication of Unlegended Regulation S Global Notes, the Trustee shall cancel the
Legended Regulation S Global Note. The aggregate principal amount of the Regulation S Global Notes
may from time to time be increased or decreased by adjustments made on the records of the Trustee
and the Depositary or its nominee, as the case may be, in connection with transfers of interest as
hereinafter provided.

          (d) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating

signature will be conclusive evidence that the Note has been authenticated under this Indenture.

Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except
as provided in Section 2.07 hereof.

          The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes authentication

-36-

 

by such agent.
An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of
the Company.

Section 2.03 Registrar and Paying Agent.

          The Company will maintain an office or agency where Notes may be presented for registration of
transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for
payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer
and exchange. The Company may appoint one or more co-registrars and one or more additional paying
agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent. The Company may change any Paying Agent or Registrar without notice to
any Holder. The Company will notify the Trustee in writing of the name and address of any Agent
not a party to this Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries
may act as Paying Agent or Registrar.

          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.

          The Company initially appoints DTC to act as Depositary with respect to the Global Notes.

          The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act
as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

          The Company will require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the
Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on
the Notes, and will notify the Trustee of any default by the Company in making any such payment.
While any such default continues, the Trustee may require a Paying Agent to pay all money held by
it to the Trustee. 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 payment over to
the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate
and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying
Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will
serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

          The Trustee will preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of all Holders and shall otherwise comply with TIA

furnish to the Trustee at least seven 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 the Holders of Notes and the Company

or unable to continue to act as Depositary or that it is no longer a clearing agency
registered under the Exchange Act and in each case a successor Depositary is not appointed

PROCEDURES GOVERNING ITS EXCHANGE FOR CERTIFICATED NOTES, ARE AS SPECIFIED IN THE

          (h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests
in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note
has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be
returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any
time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or
transferred to a Person who will take delivery thereof in the form of a beneficial interest in
another Global Note or for Definitive Notes, the principal amount of Notes represented by such
Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the
Trustee or by the Depositary 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 Note, such other Global Note will be
increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

          (i) General Provisions Relating to Transfers and Exchanges.

          (1) To permit registrations of transfers and exchanges, the Company will execute and the
Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order
in accordance with Section 2.02 hereof or at the Registrar’s request.

          (2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to
a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any transfer tax or similar governmental charge
payable in connection therewith (other than any such transfer taxes or similar governmental charge
payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 4.10, 4.15 and 9.05 hereof).

          (3) The Registrar will not be required to register the transfer of or exchange of any Note
selected for redemption in whole or in part, except the unredeemed portion of any Note being
redeemed in part.

          (4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange
of Global Notes or Definitive Notes will be the valid obligations of the

-51-

 

Company, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the Global Notes or
Definitive Notes surrendered upon such registration of transfer or exchange.

          (5) Neither the Registrar nor the Company will be required:

     (A) to issue, to register the transfer of or to exchange any Notes during a period
beginning at the opening of business 15 days before the day of any selection of Notes for
redemption under Section 3.02 hereof and ending at the close of business on the day of
selection;

     (B) to register the transfer of or to exchange any Note selected for redemption in
whole or in part, except the unredeemed portion of any Note being redeemed in part; or

     (C) to register the transfer of or to exchange a Note between a record date and the
next succeeding interest payment date.

          (6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any
Agent and the Company may deem and treat the Person in whose name any Note is registered as the
absolute owner of such Note for the purpose of receiving payment of principal of and interest on
such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be
affected by notice to the contrary.

provisions of Section 2.02 hereof.

Section 2.07 Replacement Notes.

          If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue
and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if
the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond
must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of
them may suffer if a Note is replaced. The Company may charge for their expenses in replacing a
Note.

          Every replacement Note is an additional obligation of the Company and will be entitled to all
of the benefits of this Indenture equally and proportionately with all other Notes duly issued
hereunder.

-52-

 

Section 2.08 Outstanding Notes.

          The Notes outstanding at any time are all the Notes authenticated by the Trustee except for
those canceled by it, those delivered to it for cancellation, those reductions in the interest in a
Global Note effected by the Trustee in accordance with the provisions hereof, and those described
in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does
not cease to be outstanding because the Company or an Affiliate of the Company holds the Note;
however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be
outstanding for purposes of Section 3.07(a) hereof.

          If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the
Trustee and the Registrar receive proof satisfactory to it that the replaced Note is held by a
protected purchaser.

          If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to
be outstanding and interest on it ceases to accrue.

          If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a redemption date or maturity date, money sufficient to pay all principal, premium and
accrued interest with respect to the outstanding Notes payable on that date and is not prohibited
from paying such money to the Holders thereof pursuant to the terms of Section 10 hereof, then on
and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue
interest.

Section 2.09 Treasury Notes.

          In determining whether the Holders of the required principal amount of Notes have concurred in
any direction, request, waiver or consent in the exercise of any discretion, power or authority
(whether contained in this Indenture or vested by operation of law) which the Trustee is required,
expressly or impliedly, to exercise in or by reference to the interests of the Holders or any of
them, Notes owned by the Company or 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, will be considered as though not outstanding, except that for the purposes of
determining whether the Trustee will be protected in relying on any such direction, waiver or
consent, only Notes that a Responsible Officer of the Trustee knows are so owned will be so
disregarded.

Section 2.10 Temporary Notes.

          Until certificates representing Notes are ready for delivery, the Company may prepare and the
Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary
Notes will be substantially in the form of certificated Notes but may have variations that the
Company considers appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate
definitive Notes in exchange for temporary Notes.

          Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

-53-

 

Section 2.11 Cancellation.

          The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and
Paying Agent will forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for
registration of transfer, exchange, payment, replacement or cancellation and will dispose of such
canceled Notes in its customary manner (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes will be delivered to the Company.
The Company may not issue new Notes to replace Notes that it has redeemed, purchased or paid or
that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, it will pay the defaulted
interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, in each case at the
rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and the date of the
proposed payment. The Company will fix or cause to be fixed each such special record date and
payment date; provided that no such special record date may be less than 10 days
prior to the related payment date for such defaulted interest. At least 15 days before the
special record date, the Company (or, upon the written request of the Company, the Trustee in the
name and at the expense of the Company) will mail or cause to be mailed to Holders a notice
prepared by the Company that states the special record date, the related payment date and the
amount of such interest to be paid.

Section 2.13 CUSIP Numbers and ISIN Numbers.

          The Company in issuing the Notes may use “CUSIP” numbers and “ISINs” (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers and “ISINs” in notices of redemption as a
convenience to Holders; provided that any such notice may state that no representation is made as
to the correctness of such numbers, either as printed on the Notes or as contained in any notice of
a redemption and that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or omission of such
numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP”
numbers or “ISINs.”

ARTICLE 3

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

          If the Company elects to redeem Notes pursuant to the optional redemption provisions of

     (2) the redemption date;

     (3) the principal amount of Notes to be redeemed;

          If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes
for redemption or purchase as follows:

     (1) if the Notes are listed on any national securities exchange, in compliance with the
requirements of the principal national securities exchange on which the Notes are listed; or

     (2) if the Notes are not listed on any national securities exchange, on a pro rata
basis, by lot or by such method as the Trustee shall deem fair and appropriate.

          In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or
purchased will be selected, unless otherwise provided herein, not less than 30 days nor more than
60 days prior to the redemption date by the Trustee from the outstanding Notes not previously
called for redemption.

          The Trustee will promptly notify the Company in writing of the Notes selected for redemption
and, in the case of any Note selected for partial redemption or purchase, the principal amount
thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $1,000 or whole
multiples of $1,000; provided that no Notes of $1,000 or less shall be redeemed in part. Except as
provided in the preceding sentence, provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption.

Section 3.03 Notice of Redemption.

          At least 30 days but not more than 60 days before a
redemption date, the Company will mail or cause to be mailed, by first class mail, a notice of
redemption to the Trustee and each Holder whose Notes are to be redeemed at its registered address,
except that redemption notices may be mailed more than 60 days prior to a redemption date if the
notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture pursuant to Articles 8 or 12 hereof.

          The notice will identify the Notes (including CUSIP numbers) to be redeemed and will state:

     (1) the redemption date;

-55-

 

     (2) the redemption price;

     (3) if any Note is being redeemed in part, the portion of the principal amount of such
Note to be redeemed and that, after the redemption date upon surrender of such Note, a new
Note or Notes in principal amount equal to the unredeemed portion will be issued upon
cancellation of the original Note or with respect to a Global Note a notation shall be made
on Schedule A thereto to reduce the principal amount of the Global Note to an amount equal
to the unredeemed portion of the Global Note surrendered;

     (4) the name and address of the Paying Agent;

     (5) that Notes called for redemption must be surrendered to the Paying Agent to collect
the redemption price;

     (6) that, unless the Company defaults in making such redemption payment, interest on
Notes (or portion thereof) called for redemption ceases to accrue on and after the
redemption date;

Notes called for redemption are being redeemed; and

     (8) that no representation is made as to the correctness or accuracy of the CUSIP
number, if any, listed in such notice or printed on the Notes.

          At the Company’s request, the Trustee will give the notice of redemption in the Company’s name
and at their expense; provided, however, that the Company has delivered to the Trustee, at least 45
days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided in this Section
3.03.

Section 3.04 Effect of Notice of Redemption.

          Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for
redemption become irrevocably due and payable on the redemption date at the redemption price. A
notice of redemption may not be conditional, except as set forth in Section 3.07(a) hereof.

Section 3.05 Deposit of Redemption Price.

          Prior to 10:00 a.m., New York City time, on the redemption date, the Company will deposit with
the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued
interest and Additional Interest, if any, on all Notes to be redeemed on that date. The Trustee or
the Paying Agent will promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and
accrued interest and Additional Interest, if any, on, all Notes to be redeemed.

-56-

 

          If the Company complies with the provisions of the preceding paragraph, on and after the
redemption date, interest will cease to accrue on the Notes or the portions of Notes called for
redemption. If a Note is redeemed on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest shall be paid to the Person in
whose name such Note was registered at the close of business on such record date. If any Note
called for redemption is not so paid upon surrender for redemption because of the failure of the
Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal,
from the redemption date until such principal is paid, and to the extent lawful on any
interest not paid on such unpaid principal, in each case at the rate provided in the Notes and
in Section 4.01 hereof.

Section 3.06 Notes Redeemed in Part.

          Upon surrender of a Note that is redeemed in part, the Company will issue and, upon receipt of
an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company
a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

Offering.

redeemable at the Company’s option prior to October 15, 2010; provided, however, the Company may

purchase or otherwise, so long as such acquisition does not violate the terms of this Indenture.

-66-

 

or restriction
is not applicable to any Person, or the properties or assets of any Person, other than the

contracts, instruments or obligations referred to above in clauses (1) through (15);
provided that such amendments or refinancings are not, in the good faith judgment of the

(including Acquired Debt), and the Company will not issue any Disqualified Stock and the Company
will not permit any of its Restricted Subsidiaries to issue any Disqualified Stock or preferred

Fixed Charge Coverage Ratio for the Company’s 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 such preferred equity is issued,
as the case may be, would have been at least 2.0 to 1.0, 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 the preferred equity had been issued, as the case may be, at

purchase price or cost of design, development, construction, installation or improvement of
property (real or personal and including Capital Stock), plant or equipment used in the
business of the Company or any of its Restricted Subsidiaries (in each case, whether through
the direct purchase of such assets or the Equity Interests of any Person owning such
assets), in an aggregate principal amount not to exceed, immediately after giving effect to
any such incurrence, the greater of (x) $35.0 million and (y) 5.0% of Total Assets;

     (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew,

     (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany
Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided,
however, that:

payee is not the Company or a Guarantor, such Indebtedness must be expressly
subordinated to the prior payment in full in cash of all Obligations then due with
respect to the Notes, in the case of the Company, or the Note Guarantee, in the case
of a Guarantor; and

     (B) (i) any subsequent issuance or transfer of Equity Interests that results in
any such Indebtedness being held by a Person other than the Company or a Restricted
Subsidiary of the Company, and (ii) any sale or other transfer of any such

of the Company, shall be deemed, in each case, to constitute an incurrence of such
Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that
was not permitted by this clause (6);

-69-

 

     (7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to

guarantee thereof shall be subordinated or pari passu, as applicable, to the same extent as
the Indebtedness so guaranteed;

     (10) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness in respect of workers’ compensation claims, payment obligations in connection

acquisition or merger or to provide all or a portion of the funds or credit support required
to consummate such acquisition or merger; provided further, however, that, for any such
Indebtedness, Disqualified Stock or preferred equity outstanding under this clause (12) in
excess of $10.0 million on the date such Person is

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

     (15) the incurrence by the Company or any of its Restricted Subsidiaries of additional
Indebtedness or the issuance of Disqualified Stock or preferred equity in an aggregate
principal amount (or accreted value, as applicable) or having an aggregate liquidation
preference at any time outstanding not to exceed $45.0 million (it being understood that any
Indebtedness, Disqualified Stock or preferred equity incurred pursuant to this clause (15)
shall cease to be deemed incurred or outstanding for purposes of this Section 4.09 from and
after the date on which the Company could have incurred such Indebtedness or Disqualified
Stock or preferred equity under Section 4.09(a) hereof without reliance upon this clause
(15));

     (16) the incurrence by the Company or any of its Restricted Subsidiaries of additional
Indebtedness arising out of advances on exports, advances on imports, advances on trade
receivables, factoring of receivables, customer prepayments and similar transactions in the
ordinary course of business and consistent with past practice;

     (17) the incurrence of additional Indebtedness by a Foreign Subsidiary in an aggregate
principal amount which does not exceed the greater of (a) $30.0 million or (b) 3.5% of the
Total Assets at any one time outstanding (which amount may, but need not, be incurred in
whole or in part under a Credit Facility);

     (18) Indebtedness of the Company or any of its Restricted Subsidiaries in respect of
the Management Notes; and

-71-

 

     (19) Contribution Indebtedness.

          For purposes of determining compliance with this Section 4.09, in the event that an item of
proposed Indebtedness, Disqualified Stock or preferred equity meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (19) above or is entitled to
be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify such item
of Indebtedness, Disqualified Stock or preferred equity on the date of its incurrence and will only
be required to include the amount and type of such Indebtedness, Disqualified Stock or preferred
equity in one of the above clauses, although the Company may divide and classify an item of
Indebtedness, Disqualified Stock or preferred equity in one or more of the types of Indebtedness,
Disqualified Stock or preferred equity and may later reclassify all or a portion of such item of
Indebtedness, Disqualified Stock or preferred equity, in any manner that complies with this Section
4.09. The accrual of interest or dividends, the accretion or amortization of original issue
discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with
the same terms, the reclassification of preferred equity as Indebtedness due to a change in
accounting principles, and the payment of dividends on Disqualified Stock or preferred equity in
the form of additional shares of the same class of Disqualified Stock or preferred equity will not
be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred
equity for purposes of this Section 4.09; provided, in each such case (other than preferred stock
that is not Disqualified Stock), that the amount of any such accrual, accretion or payment is
included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this
Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of
fluctuations in exchange rates or currency values.

          The amount of any Indebtedness outstanding as of any date will be:

     (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with
original issue discount;

     (2) the principal amount of the Indebtedness, in the case of any other Indebtedness;
and

     (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the
specified Person, the lesser of:

     (A) the Fair Market Value of such assets at the date of determination; and

     (B) the amount of the Indebtedness of the other Person.

Section 4.10 Asset Sales.

          The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an
Asset Sale unless:

     (1) The Company (or the Restricted Subsidiary, as the case may be) receives
consideration at the time of the Asset Sale at least equal to the Fair Market Value of the
assets or Equity Interests issued or sold or otherwise disposed of; and

     (2) at least 75% of the consideration received in the Asset Sale by the Company or such
Restricted Subsidiary is in the form of cash, Cash Equivalents or Marketable Securities.
For purposes of this provision, each of the following shall be deemed to be cash:

     (A) any liabilities of the Company or any Restricted Subsidiary of the Company
(other than contingent liabilities and liabilities that are by their terms
subordinated to the Notes or any Note Guarantee) that are assumed by the transferee
of any such assets and as a result of which, the Company or such Restricted
Subsidiary of the Company are released from any further liability in connection
therewith;

     (B) any securities, notes, other obligations or assets received by the Company
or any such Restricted Subsidiary from such transferee that are converted by the
Company or such Restricted Subsidiary into cash or Cash Equivalents within 180 days
of the receipt thereof, to the extent of the cash or Cash Equivalents received in
that conversion;

     (C) any Designated Non-cash Consideration received by the Company or any of its
Restricted Subsidiaries in such Asset Sale; provided that the aggregate Fair Market
Value of such Designated Non-cash Consideration, taken together with the Fair Market
Value at the time of receipt of all other Designated Non-cash Consideration received
pursuant to this clause (C), less the amount of Net Proceeds previously realized in
cash from prior Designated Non-cash Consideration is less than the greater of (x)
2.5% of Total Assets 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) and (y) $17.5 million; and

     (D) any Capital Stock or assets of the kind referred to in clause (2) or (4) of
the next paragraph of this Section 4.10.

          Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the
applicable Restricted Subsidiary, as the case may be) may:

-73-

 

     (a) apply such Net Proceeds, at its option:

     (1) to repay (w) Indebtedness and other Obligations constituting Senior
Indebtedness, (x) any Indebtedness that was secured by the assets sold in such Asset
Sale, (y) other pari passu Indebtedness (provided that the Company shall also
equally and ratably reduce Indebtedness under the Notes by making an offer (in
accordance with the procedures set forth below for an Asset Sale) to all Holders to
purchase at a purchase price equal to 100% of the principal amount thereof, plus
accrued and unpaid interest and Additional Interest, if any, the pro rata principal
amount of Notes), or (z) Indebtedness of a Restricted Subsidiary that is not a
Guarantor, in each case other than Indebtedness owed to any Parent, the Company or
any of their respective Affiliates;

     (2) to acquire all or substantially all of the assets of, or any Capital Stock
of, another Permitted Business; provided that in the case of any such acquisition of
Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the
Company;

     (3) to make a capital expenditure; or

     (4) to acquire other assets that are not classified as current assets under
GAAP and that are used or useful in a Permitted Business; or

     (b) enter into a binding commitment to apply the Net Proceeds pursuant to clause (a)
(2), (3) or (4) above, provided that such binding commitment shall be treated as a permitted
application of the Net Proceeds from the date of such commitment until the earlier of (x)
the date on which such acquisition or expenditure is consummated, and (y) the 180th day
following the expiration of the aforementioned 365 day period.

Pending the final application of any Net Proceeds, the Company may temporarily reduce revolving
credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this
Indenture.

          Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second
paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of
Excess Proceeds exceeds $15.0 million, within ten Business Days thereof, the Company will make an
offer to all Holders (an “Asset Sale Offer”) and all holders of other Indebtedness that is pari
passu with the Notes containing provisions similar to those set forth in this Indenture with
respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out
of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the
principal amount of the Notes and such other pari passu Indebtedness plus accrued and unpaid
interest and Additional Interest, if any, on the Notes and such other pari passu Indebtedness, to,
but excluding, the date of purchase and will be payable in cash. If any Excess Proceeds remain
after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and
other pari passu Indebtedness tendered into such Asset Sale Offer

-74-

 

exceeds the amount of Excess Proceeds, the Notes and such other pari passu Indebtedness to be
purchased shall be purchased on a pro rata basis based on the principal amount of Notes and such
other pari passu Indebtedness tendered. In such event, the Trustee shall select the Notes to be
purchased as provided in this Section 4.10. Upon completion of each Asset Sale Offer, the amount
of Excess Proceeds will be reset at zero.

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

          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 4.10. 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 Notes or portions thereof that have been properly tendered to and are to be accepted by the
Company. Upon receipt from the Company of the purchase price for the Notes accepted for payment,
the Trustee shall promptly (but in any case not later than the Business Day after the Trustee
receives such amounts) mail or deliver to each tendering Holder an amount equal to the purchase
price of the Notes tendered by such Holder and accepted by the Company for purchase. In the event
that the Excess Proceeds delivered by the Company to the Trustee is greater than the purchase price
of the Notes tendered, the Trustee shall deliver the excess to the Company immediately after the
expiration of the Offer Period for application in accordance with this Section 4.10.

          Holders electing to have a Note purchased shall be required to surrender the Note, with the
form entitled “Option of Holder to Elect Purchase” attached to the Note 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 Note which
was delivered by the Holder for purchase and a statement that such Holder is withdrawing his
election to have such Note purchased. If at the end of the Offer Period more Notes are tendered
pursuant to an Asset Sale Offer than the Company is required to purchase, selection of such Notes
for purchase shall be made by the Trustee in accordance with Section 3.02 hereof; provided that no
Notes of $1,000 or less shall be purchased in part.

          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 at such Holder’s registered
address. If any Note 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.

-75-

 

          A new Note in principal amount equal to the unpurchased portion of any Note purchased in part
shall be issued in the name of the Holder thereof upon cancellation of the original Note in
accordance with Section 2.02 hereof. On and after the purchase date, unless the Company defaults
in payment of the purchase price, interest shall cease to accrue on Notes or portions thereof
purchased.

Section 4.11 Transactions with Affiliates.

          (a) the Company will not, and will not permit any of its Restricted Subsidiaries to, 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, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of
the Company (each, an “Affiliate Transaction”), involving aggregate consideration in excess of $1.0
million, unless:

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

     (2) the Company delivers to the Trustee:

     (A) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $5.0 million, a
resolution of the Board of Directors of the Company certifying that such Affiliate
Transaction complies with this Section 4.11 and that such Affiliate Transaction has
been approved by a majority of the disinterested members, if any, of the Board of
Directors of the Company; and

     (B) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $25.0 million, an
opinion as to the fairness to the Company or such Restricted Subsidiary of such
Affiliate Transaction from a financial point of view issued by an accounting,
appraisal or investment banking firm of national standing.

          (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will
not be subject to the provisions of Section 4.11(a) hereof:

     (1) any employment agreement, employee benefit plan, officer or director
indemnification agreement or any similar arrangement entered into by the Company or any of
its Restricted Subsidiaries in the ordinary course of business or consistent with past
practice and payments pursuant thereto;

     (2) transactions (including a merger) between or among the Company and/or any of its
Restricted Subsidiaries;

-76-

 

     (3) transactions with a Person (other than an Unrestricted Subsidiary of the Company)
that is an Affiliate of the Company solely because the Company owns, directly or through a
Restricted Subsidiary, an Equity Interest in, or controls, such Person;

     (4) payment of reasonable fees to, and indemnity provided on behalf of, officers,
directors, employees or consultants of the Company or any of its Restricted Subsidiaries or
any Parent;

     (5) any issuance of Equity Interests (other than Disqualified Stock) of the Company to
Affiliates of the Company or to any director, officer, employee or consultant of the Company
or any Parent, and the granting and performance of registration rights;

     (6) Restricted Payments and Investments that do not violate Section 4.07 hereof;

     (7) the entering into any agreement to pay, and the payment of, customary annual
management, consulting, monitoring and advisory fees to the Equity Investors in an amount
not to exceed in any four quarter period the greater of (x) $2.5 million and (y) 2.0% of
Consolidated Cash Flow of the Company and its Restricted Subsidiaries for such period;

     (8) loans or advances to employees or consultants in the ordinary course of business or
consistent with past practice not to exceed $2.5 million in the aggregate at any one time
outstanding;

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

     (10) any transaction in which the Company or any of its Restricted Subsidiaries, as the
case may be, delivers to the Trustee a letter from an accounting, appraisal or investment
banking firm of national standing stating that such transaction is fair to the Company or
such Restricted Subsidiary from a financial point of view or that such transaction meets the
requirements of clause (1) of Section 4.11(a);

     (11) the existence of, or the performance by the Company or any of its Restricted
Subsidiaries of its obligations under the terms of, any acquisition agreements or members’
or stockholders agreement or related documents to which it is a party as of the date of this
Indenture and any amendment thereto or similar agreements which it may enter into
thereafter; provided, however, that the existence of, or the performance by the Company 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 date of this
Indenture shall only be permitted by this clause (11) to the extent that the terms of any
such existing agreement, together with all amendments thereto, taken as a whole, or such new
agreement are not, in the good faith judgment of the Company’s Board of Directors, otherwise
more disadvantageous to the Holders of the Notes taken as a whole than the original
agreement as in effect on the date of this Indenture;

-77-

 

     (12) transactions with Unrestricted Subsidiaries, customers, clients, suppliers, joint
venture partners or purchasers or sellers of goods or services, or lessors or lessees of
property, in each case in the ordinary course of business and otherwise in compliance with
the terms of this Indenture which are, in the aggregate (taking into account all the costs
and benefits associated with such transactions), materially no less favorable to the Company
or its Restricted Subsidiaries than those that would have been obtained in a comparable
transaction by the Company or such Restricted Subsidiary with an unrelated Person, in the
good faith judgment of the Company’s Board of Directors or senior management thereof, or are
on terms at least as favorable as might reasonably have been obtained at such time from an
unaffiliated party;

     (13) (x) guarantees of performance by the Company and its Restricted Subsidiaries of
Unrestricted Subsidiaries of the Company in the ordinary course of business, except for
guarantees of Indebtedness in respect of borrowed money, and (y) pledges of Equity Interests
of Unrestricted Subsidiaries of the Company for the benefit of lenders of Unrestricted
Subsidiaries of the Company;

     (14) if such Affiliate Transaction is with a Person in its capacity as a holder of
Indebtedness or Capital Stock of the Company or any Restricted Subsidiary where such Person
is treated no more favorably than the holders of Indebtedness or Capital Stock of the
Company or any Restricted Subsidiary;

     (15) transactions effected pursuant to agreements in effect on the Issue Date and any
amendment, modification or replacement of such agreement (so long as such amendment or
replacement is not, in the good faith judgment of the Company’s Board of Directors,
materially more disadvantageous to the Holders of the Notes, taken as a whole, than the
original agreement as in effect on the Issue Date);

     (16) payments to the Equity Investors made for any financial advisory, financing or
other investment banking activities, including without limitation, in connection with
acquisitions or divestitures, which payments are approved by a majority of the Company’s
Board of Directors; and

     (17) the issuance of Management Notes.

Section 4.12 Liens.

          The Company will not, and will not permit any of its Restricted Subsidiaries to, create,
incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind
securing Indebtedness (other than Permitted Liens) that ranks pari passu with or is subordinated to
the Notes or the Note Guarantees upon any of their property or assets, now owned or hereafter
acquired, unless all payments due under this Indenture and the Notes are secured on an equal and
ratable basis with the obligations so secured (or, in the case of subordinated Indebtedness,
contractually prior or senior thereto, with the same relative priority as the Notes shall have with
respect to such subordinated Indebtedness) until such time as such obligations are no longer
secured by a Lien.

-78-

 

Section 4.13 Business Activities.

     The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any
business other than Permitted Businesses, except to such extent as would not be material to the
Company and its Restricted Subsidiaries taken as a whole.

Section 4.14 Intentionally Omitted.

Section 4.15 Offer to Repurchase upon Change of Control.

     (a) Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of
Control Offer”) to each Holder of the Notes to repurchase all or any part (equal to $1,000 or an
integral multiple of $1,000) of that Holder’s Notes at a purchase price in cash equal to 101% of
the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional
Interest, if any, on the Notes repurchased to, but not including, the date of purchase, subject to
the rights of Holders on the relevant record date to receive interest due on the relevant interest
payment date (the “Change of Control Payment”). Within 30 days following any Change of Control,
except to the extent that the Company has exercised its right to redeem the Notes in accordance
with Article 3 of this Indenture, the Company will mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and stating:

     (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and
that all Notes properly tendered pursuant to such Change of Control Offer will be accepted
for payment;

     (2) the purchase price and the purchase date, which shall be no earlier than 30 days
and no later than 60 days from the date such notice is mailed (the “Change of Control
Payment Date”);

     (3) that any Note not tendered will continue to accrue interest;

     (4) that, unless the Company defaults in the payment of the Change of Control Payment,
all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue
interest after the Change of Control Payment Date;

     (5) that Holders electing to have any Notes purchased pursuant to a Change of Control
Offer will be required to surrender the Notes, with the form entitled “Option of Holder to
Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the
Trustee at the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date;

     (6) that Holders will be entitled to withdraw their election if the Trustee receives,
not later than the close of business on the second Business Day preceding the Change of
Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of Notes delivered for purchase, and a statement
that such Holder is withdrawing his election to have the Notes purchased; and

-79-

 

             (7) that Holders whose Notes are being purchased only in part will be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered, which
unpurchased portion must be equal to $1,000 in principal amount or an integral multiple
thereof.

             The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent those laws and regulations are
applicable in connection with the repurchase of the Notes as a result of a Change in Control. To
the extent that the provisions of any securities laws or regulations conflict with the provisions
of this Section 4.15 hereof, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached their obligations under this Section 4.15 by
virtue of such compliance.

     (b) On the Change of Control Payment Date, the Company will, to the extent lawful:

     (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the
Change of Control Offer;

     (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions of Notes properly tendered; and

     (3) deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officers’ Certificate stating the aggregate principal amount of Notes or
portions of Notes being purchased by the Company.

          The Paying Agent will promptly mail or wire transfer to each Holder properly tendered and so
accepted the Change of Control Payment for such Notes. The Company will execute and, upon receipt
of an Authentication Order in accordance with Section 2.02 hereof, the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in
principal amount to any unpurchased portion of the Notes surrendered, if any; provided, that each
new Note will be in a principal amount of $1,000 or an integral multiple of $1,000. Any Note so
accepted for payment will cease to accrue interest on and after the Change of Control Payment Date.
The Company will publicly announce the results of the Change of Control Offer on or as soon as
reasonably practicable after the Change of Control Payment Date.

             (c) Notwithstanding anything to the contrary in this Section 4.15, the Company will not be
required to make a Change of Control Offer upon a Change of Control if (1) 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 this Section 4.15 and purchases all Notes properly
tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has
been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the
applicable redemption price.

-80-

 

Section 4.16 Payments for Consent.

          The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder or as an
inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Notes unless such consideration is offered to be paid and is paid to all Holders that
consent, waive or agree to amend in the time frame set forth in the solicitation documents relating
to such consent, waiver or agreement.

Section 4.17 Additional Note Guarantees.

          If the Company or any of its Restricted Subsidiaries acquires or creates another wholly owned
Domestic Subsidiary on or after the date of this Indenture, then that newly acquired or created
Domestic Subsidiary, if such Subsidiary guarantees any Indebtedness of the Company (unless such
Subsidiary is a Receivables Subsidiary), shall become a Guarantor (which Note Guarantee shall be
senior to or pari passu with such Restricted Subsidiary’s guarantee of such other Indebtedness
unless such other Indebtedness is Senior Indebtedness, in which case the Note Guarantee may be
subordinated to the guarantee of such Senior Indebtedness to the same extent as the Notes are
subordinated to such Senior Indebtedness) and execute a supplemental indenture and deliver an
Opinion of Counsel satisfactory to the Trustee within 30 days of the date on which it guaranteed
such other Indebtedness; provided that any Domestic Subsidiary that constitutes an Immaterial
Subsidiary need not become a Guarantor until such time as it (i) ceases to be an Immaterial
Subsidiary or (ii) guarantees the Credit Agreement. The form of such supplemental indenture is
attached hereto as Exhibit E hereto.

Section 4.18 Designation of Restricted and Unrestricted Subsidiaries.

          The Board of Directors of the Company may designate any Restricted Subsidiary, other than the
Company, to be an Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value
of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the
Subsidiary designated as Unrestricted shall be deemed to be an Investment made as of the time of
the designation and will reduce the amount available for Restricted Payments under Section 4.07
hereof or under one or more clauses of such definition of Permitted Investments, as determined by
the Company. That designation will only be permitted if such Investment would be permitted at that
time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.
The Board of Directors of the Company may designate
any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not
cause a Default.

          Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced
to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of
Directors of the Company giving effect to such designation and an Officers’ Certificate certifying
that such designation complied with the preceding conditions and was permitted by Section 4.07
hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements
as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for
purposes of this Indenture and any Indebtedness of such Subsidiary

-81-

 

will be deemed to be incurred by
a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted
to be incurred as of such date under Section 4.09 hereof, the Company will be in Default of such
covenant. The Board of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be
deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any
outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be
permitted if (1) (x) the Company could incur such Indebtedness pursuant to the Fixed Charge
Coverage Ratio test, described in Section 4.09(a) hereof, or (y) the Fixed Charge Coverage Ratio
for the Company and its Restricted Subsidiaries would be greater than such ratio for the Company
and its Restricted Subsidiaries immediately prior to such designation, in each case on a pro forma
basis taking into account such designation; and (2) no Default or Event of Default would be in
existence following such designation.

Section 4.19 Changes in Covenants upon Notes Being Rated Investment Grade.

          If on any date following the Issue Date: (i) the Notes are assigned an Investment Grade
Rating from both of the Rating Agencies and (ii) no Default or Event of Default shall have occurred

beginning on that day, the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.15
and 4.18 hereof, and clause (4) of Section 5.01 shall terminate (provided that failure to provide
such notice shall not result in a Default or Event of Default or the Company having to comply with
such provisions).

     (1) default for 30 days in the payment when due of interest on, or Additional Interest,
if any, with respect to the Notes, whether or not such payment is prohibited by the
provisions described in Article 10 hereof;

principal of, or premium, if any, on the Notes, whether or not such payment is prohibited by

     (5) default under any mortgage, indenture or instrument under which there may be issued
or by which there may be secured or evidenced any Indebtedness for money borrowed by the
Company or any of its Significant Subsidiaries or group of Restricted Subsidiaries that
taken as a whole would constitute a Significant Subsidiary (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness
or guarantee now exists, or is created after the
date of this Indenture (but excluding Indebtedness owing to the Company or a Restricted
Subsidiary), if that default:

     (A) is caused by a failure to pay principal on such Indebtedness after the
expiration of the grace period provided in such Indebtedness upon the Stated
Maturity of such Indebtedness (a “Payment Default”); or

     (B) results in the acceleration of such Indebtedness prior to its Stated
Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a Payment Default
or the maturity of which has been so accelerated, aggregates $15.0 million or more;

jurisdiction aggregating in excess of $15.0 million (net of any amounts which are covered by
insurance or bonded), which judgments are not paid, waived, satisfied, discharged or stayed
for a period of 60 days;

     (7) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary
or any group of Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary pursuant to or within the meaning of Bankruptcy Law:

     (A) commences a voluntary case,

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

     (C) consents to the appointment of a custodian of it or for all or
substantially all of its property, or

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

     (A) is for relief against the Company or any of its Restricted Subsidiaries
that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together, would constitute a Significant Subsidiary in an involuntary case;

     (B) appoints a custodian of the Company or any of its Restricted Subsidiaries

ceases for any reason to be in full force and effect (other than in accordance with the
terms of such Note Guarantee and this Indenture), or any Guarantor, or any Person acting on
behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee and
such Default continues for 10 days.

Section 6.02 Acceleration.

          In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with
respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary
or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a
Significant Subsidiary, all outstanding Notes will become due and payable immediately without
further action or notice. If any other Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare
all the Notes to be due and payable immediately; provided that any such declaration of acceleration
shall not become effective until the earlier of (x) five Business Days after receipt of the
acceleration notice by the Bank Agent and the Company or (y) acceleration of the Indebtedness under
the Credit Agreement; provided further that such acceleration shall be automatically rescinded and
annulled without any further action required on the part of the Trustee or the Holders in the event
that any and all Events of Default specified in the acceleration notice under this Indenture shall
have been cured, waived or otherwise remedied as provided in this Indenture prior to the expiration
of the period referred to in the preceding clauses (x) and (y).

          Upon any such declaration, the Notes shall become due and payable immediately.

          The Holders of a majority in aggregate principal amount of the then outstanding Notes by
written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its
consequences, if the rescission would not conflict with any judgment or decree and if all existing
Events of Default (except nonpayment of principal, interest or premium or Additional Interest, if
any, that has become due solely because of the acceleration) have been cured or waived.

          In the event of any Event of Default specified in clause (5) of Section 6.01, such Event of
Default and all consequences thereof (excluding, however, any resulting payment default) will be
annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders
of the Notes, if within 30 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 Notes 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
to collect the payment of principal, premium and Additional Interest, if any, and interest on the
Notes or to enforce the performance of any provision of the Notes or this Indenture.

-86-

 

          The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note
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. All remedies are
cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

          Holders of not less than a majority in aggregate principal amount of the then outstanding
Notes by notice to the Trustee may on behalf of the Holders of all of the Notes rescind an
acceleration or waive an existing Default or Event of Default and its consequences hereunder,
except a continuing Default or Event of Default in the payment of the principal of, premium and
Additional Interest, if any, or interest on, the Notes (including in connection with an offer to
purchase). Upon any such rescission or waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon.

Section 6.05 Control by Majority.

          Holders of a majority in aggregate principal amount of the then outstanding Notes may direct
the time, method and place of conducting any proceeding for exercising any remedy available to the
Trustee or exercising any trust or power conferred on it. However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture that the Trustee
determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve
the Trustee in personal liability.

Section 6.06 Limitation on Suits.

             A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

     (1) such Holder has previously given the Trustee written notice that an Event of
Default is continuing;

     (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes
make a written request to the Trustee to pursue the remedy;

     (3) such Holder or Holders offer and, if requested, provide to the Trustee security or
indemnity satisfactory to the Trustee against any loss, liability or expense;

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

     (5) during such 60-day period, Holders of a majority in aggregate principal amount of
the then outstanding Notes do not give the Trustee a direction inconsistent with such
request.

-87-

 

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to
receive payment of principal, premium and Additional Interest, if any, and interest on the Note, on
or after the respective due dates expressed in the Note (including in connection with an offer to
purchase), 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(1) or (2) hereof occurs and is continuing,
the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount of principal of, premium and Additional Interest, if any,
and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

          The Trustee is authorized to 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 the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property, shall be entitled to
participate as a member, voting or otherwise, of any official committee of creditors appointed in
such matter and shall be entitled and empowered to collect, receive and distribute any money or
other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such 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 to it for the reasonable and documented compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied
for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any
and all distributions, dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan of reorganization
or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

-88-

money or property in the following order:

     First: to the Trustee, its agents and attorneys for amounts due under Section 7.07
hereof, including payment of all compensation, expenses, disbursements and liabilities
incurred by the Trustee, its counsel and agents and the costs and expenses of collection;

premium and Additional Interest, if any, and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for principal,

     Third: to the Company or, to the extent the Trustee collects any amounts for any
Guarantor, to such Guarantor or to such party as a court of competent jurisdiction shall
direct in writing.

pursuant to this Section 6.10. 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 a 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 and
documented attorneys’ fees and expenses against any party litigant in the suit, having due regard
to the merits and good faith of the claims or defenses made by the party litigant. This Section
6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07

Section 7.01 Duties of Trustee.

             (a) The Trustee, prior to the occurrence of an Event of Default of which a Responsible Officer
of the Trustee shall have actual knowledge and after the curing of all such Events of Defaults
which may have occurred, undertakes to perform such duties and only such duties as are specifically
set forth in this Indenture. If an Event of Default of which a Responsible Officer of the Trustee
shall have actual knowledge has occurred and is continuing, the Trustee will exercise such of the
rights and powers vested in it by this Indenture, and use the

-89-

 

same degree of care and skill in its
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:

     (1) the duties of the Trustee will be determined solely by the express provisions of
this Indenture and the Trustee need perform only those duties that are specifically set

     (2) 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, with respect to certificates or opinions specifically required by any
provision hereof to be furnished to it, the Trustee will examine the certificates and
opinions to determine whether or not they conform to the requirements of this Indenture;
provided, however, that the Trustee shall not be responsible for the accuracy or content of
any resolution, certificate, statement, opinion, report, document, order or other instrument
furnished to it hereunder.

negligent failure to act, or its own willful misconduct, except that:

     (1) this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

     (2) the Trustee will not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the
pertinent facts; and

     (3) the Trustee will 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 hereof.

incur any liability for the performance of any of its duties hereunder or the exercise of any of
its rights or powers. The Trustee will be under no obligation to exercise any of its rights and
powers under this Indenture at the request of any Holders, unless such Holder has offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or expense.

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

or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits
to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee

Counsel will be full and complete authorization and protection from
liability in respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

          (c) The Trustee may execute any of the trusts or powers hereunder and perform any duties
hereunder either directly or through its attorneys and agents and will not be responsible for the

offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and
expenses that might be incurred by it in compliance with such request or direction.

          (g) in no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action;

Trustee, and such notice references the Notes and this Indenture;

          (i) the rights, privileges, protections, immunities and benefits given to the Trustee,

enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder;

shall not at any time be under any duty or responsibility to any Holders to determine whether the
Additional Interest is payable and the amount thereof.

Section 7.03 Individual Rights of Trustee.

          The Trustee in its individual or any other capacity may become the owner or pledgee of Notes
and may otherwise deal with the Company or any Affiliate of the Company with the same rights it
would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for permission to

withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted
by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the
exercise or performance of any of its powers or duties hereunder, except to the extent any such
loss, liability or expense may be attributable to its own negligence, bad faith or willful
misconduct. The Trustee will notify the Company promptly of any claim of which a Responsible
Officer has received written notice for which it may seek indemnity. Failure by the Trustee to so
notify the Company will not relieve the Company or any of the Guarantors of their obligations
hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in
the defense. The Trustee may have separate counsel and the Company and the Guarantors, as
applicable, will pay the reasonable and documented fees and expenses of such counsel provided,
however that the Company and any Guarantor 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. Neither the Company nor any Guarantor need pay for any
settlement made without its consent, which consent will not be unreasonably withheld.

-93-

 

          (c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the
satisfaction and discharge of this Indenture.

          (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the
Trustee will have a Lien prior to the Notes on all money or property held or collected by the
Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien
will survive the satisfaction and discharge of this Indenture.

          (e) When the Trustee incurs expenses or renders services after an Event of Default specified
in Section 6.01(7) or (8) hereof occurs, the expenses and the compensation for the services
(including the fees and expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law.

          (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable.

Section 7.08 Replacement of Trustee.

          (a) A resignation or removal of the Trustee and appointment of a successor Trustee will become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section
7.08.

          (b) The Trustee may resign in writing at any time and be discharged from the trust hereby
created by so notifying the Company. The Holders of a majority in aggregate principal amount of
the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in
writing. The Company may remove the Trustee if:

   (1) the Trustee fails to comply with Section 7.10 hereof;

   (2) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered
with respect to the Trustee under any Bankruptcy Law;

   (3) a custodian, receiver or public officer takes charge of the Trustee or its
property; or

   (4) the Trustee becomes incapable of acting.

          (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for
any reason, the Company will promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then
outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

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

-94-

 

          (e) If the Trustee, after written request by any Holder who has been a Holder for at least six
months, fails to comply with Section 7.10 hereof, such Holder may petition at the expense of the
Company any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

          (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will
become effective, and the successor Trustee will have all the rights, powers and duties of the
Trustee under this Indenture. The successor Trustee will mail a notice of its succession to
Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the
successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to
the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the
benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, Etc.

          If the Trustee consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation without any further
act will be the successor Trustee.

Section 7.10 Eligibility; Disqualification.

          There will at all times be a Trustee hereunder that is a corporation organized and doing
business under the laws of the United States of America or of any state thereof that is authorized
under such laws to exercise corporate trustee power, that is subject to supervision or examination
by federal or state authorities and that has a combined capital and surplus of at least $50.0
million as set forth in its most recent published annual report of condition.

          This Indenture will always have a Trustee who satisfies the requirements of TIA § 310(a)(1),
(2) and (5). The Trustee is subject to TIA § 310(b).

Section 7.11 Preferential Collection of Claims Against the Company.

          The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA §
311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent
indicated therein.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

          The Company may at any time, at the option of its Board of Directors evidenced by a resolution
set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied
to all outstanding Notes and Note Guarantees upon compliance with the conditions set forth below in
this Article 8.

-95-

 

Section 8.02 Legal Defeasance and Discharge.

          Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions
set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with
respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set
forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance
means that the Company and the Guarantors will be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will
thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all
their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee,
on demand of and at the expense of the Company, shall execute proper instruments acknowledging the
same), except for the following provisions which will survive until otherwise terminated or
discharged hereunder:

     (1) the rights of Holders of outstanding Notes to receive payments in respect of the
principal of, or interest or premium and Additional Interest, if any, on, such Notes when
such payments are due from the trust referred to in Section 8.04 hereof;

     (2) the Company’s obligations with respect to such Notes under Article 2 and Section
4.02 hereof;

     (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company’s and the Guarantors’ obligations in connection therewith; and

     (4) this Article 8.

          Subject to compliance with this Article 8, the Company may exercise its option under this
Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

          Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions
set forth in Section 8.04 hereof, be released from each of their obligations under the covenants
contained in Sections 4.03, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18
and 4.19 and clauses (3) and (4) of Section 5.01 hereof with respect to the outstanding Notes on
and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter,
“Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes
of any direction, waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all
other purposes hereunder (it being understood that such Notes will not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and
will have no liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any

-96-

 

reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other provision herein or in any
other document and such omission to comply will not constitute a Default or an Event of Default
under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such
Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise
under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(6)
hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

     In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02
or 8.03 hereof:

     (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination
thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized
investment bank, appraisal firm, or firm of independent public accountants, to pay the
principal of, premium and Additional Interest, if any, and interest on, the outstanding
Notes on the stated date for payment thereof or on the applicable redemption date, as the
case may be, and the Company must specify whether the Notes are being defeased to such
stated date for payment or to a particular redemption date;

     (2) in the case of an election under Section 8.02 hereof, the Company must deliver to
the Trustee an Opinion of Counsel (subject to customary exceptions and exclusions)
confirming that:

          (A) the Company has received from, or there has been published by, the Internal
Revenue Service a ruling; or

          (B) 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 of the outstanding Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;

     (3) in the case of an election under Section 8.03 hereof, the Company must deliver to
the Trustee an Opinion of Counsel (subject to customary exceptions and exclusions)
confirming that the Holders of the outstanding Notes will not recognize income, gain or loss
for federal income tax purposes as a result of such Covenant 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 Covenant Defeasance had not occurred;

-97-

 

     (4) no Default or Event of Default shall have occurred and be continuing on the date of
such deposit (other than a Default or Event of Default resulting from, or arising in
connection with, the borrowing of funds to be applied to such deposit and the grant of any
Lien securing such borrowing);

     (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under, any material agreement or instrument (other
than this Indenture) to which the Company or any of its Subsidiaries is a party or by which
the Company or any of its Subsidiaries is bound, including the Credit Agreement;

     (6) the Company is not prohibited from making payments in respect of the Notes by the
provisions described in Article 10 hereof;

     (7) the Company must deliver to the Trustee an Officers’ Certificate stating that the
deposit was not made by the Company with the intent of preferring the Holders over the other
creditors of the Company with the intent of defeating, hindering, delaying or defrauding any
creditors of the Company or others; and

     (8) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.

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

Section 8.05 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous
Provisions.

            Subject to Section 8.06 hereof, all money and non-callable Government Securities (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the
outstanding Notes will be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders
of such Notes of all sums due and to become due thereon in respect of principal, premium and
Additional Interest, if any, and interest, but such money need not be segregated from other funds
except to the extent required by law.

            The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or non-callable Government Securities deposited pursuant to Section
8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of the outstanding Notes.

            Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to
the Company from time to time upon the request of the Company any money or non-callable Government
Securities held by it as provided in Section 8.04 hereof which, in the

-98-

 

opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in
excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

          Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, premium or Additional Interest, if any, or interest on,
any Note and remaining unclaimed for two years after such principal, premium or Additional
Interest, if any, or interest has become due and payable shall be paid to the Company on its
request or (if then held by the Company) will be discharged from such trust; and the Holder of such
Note will thereafter be permitted to look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the expense of the
Company causes to be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which will not be less than 30 days from the date of such notification or
publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07 Reinstatement.

          If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government
Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company’s and the Guarantors’ obligations under this
Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit
had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case
may be; provided, however, that, if the Company makes any payment of principal of, premium or
Additional Interest, if any, or interest on, any Note following the reinstatement of its
obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive
such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

          Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee
may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of
any Holder:

          (1) to cure any ambiguity, defect or inconsistency;

-99-

 

     (2) to provide for uncertificated Notes in addition to or in place of certificated
Notes;

     (3) to provide for the assumption of the Company’s or a Guarantor’s obligations to the
Holders of the Notes and Note Guarantees by a successor to the Company or such Guarantor
pursuant to Article 5 or Article 11 hereof;

     (4) to make any change that would provide any additional rights or benefits to the
Holders or that does not adversely affect the legal rights hereunder of any Holder;

     (5) to comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA;

     (6) to conform the text of this Indenture or the Notes to any provision of the
“Description of the Notes” section of the Offering Memorandum, to the extent that such
provision in that “Description of the Notes” was intended to be a verbatim recitation of a
provision of this Indenture, the Note Guarantees or the Notes;

     (7) to provide for the issuance of Additional Notes in accordance with the limitations
set forth in this Indenture as of the date hereof;

     (8) to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee
with respect to the Notes and to release Guarantors from the Note Guarantee in accordance
with the terms of this Indenture;

     (9) to comply with the rules of any applicable securities depositary; or

     (10) to provide for a successor Trustee in accordance with the terms of this Indenture
or to otherwise comply with any requirement of this Indenture.

          Upon the request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amended or supplemental indenture, and upon receipt by the
Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company
and the Guarantors in the execution of any amended or supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee will not be obligated to enter into
such amended or supplemental indenture that affects its own rights, duties or immunities under this
Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

          Except as provided below in this Section 9.02, the Company, the Guarantors and the Trustee may
amend or supplement this Indenture (including, without limitation, Sections 4.10 and 4.15 hereof)
and the Notes or the Note Guarantee with the consent of the Company and Holders of at least a
majority in aggregate principal amount of the then outstanding Notes voting as a single class
(including, without limitation, consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing
Default or Event of Default (other than a Default or Event of Default in the

-100-

 

payment of the
principal of, premium or Additional Interest, if any, or interest on, the Notes, except a payment
default resulting from an acceleration that has been rescinded) or compliance with any provision of
this Indenture or the Notes or the Note Guarantee may be waived with the consent of the Company and
Holders of a majority in aggregate principal amount of the then outstanding Notes (including,
without limitation, Additional Notes, if any) voting as a single class (including, without
limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding”
for purposes of this Section 9.02.

          Upon the request of the Company accompanied by a resolution of its Board of Directors
authorizing the execution of any such amended or supplemental indenture, and upon
the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the
Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of
such amended or supplemental indenture unless such amended or supplemental indenture directly
affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but will not be obligated to, enter into such amended or
supplemental Indenture.

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

          After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Company will mail to the Holders of Notes affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect
therein, will not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in
aggregate principal amount of the Notes then outstanding voting as a single class may waive
compliance in a particular instance by the Company with any provision of this Indenture or the
Notes or the Note Guarantees. However, without the consent of the Company and each Holder
affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any
Notes held by a non-consenting Holder):

     (1) reduce the principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver;

     (2) reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to the redemption of the Notes (other than provisions relating to
Sections 4.10 and 4.15 hereof);

     (3) reduce the rate of or change the time for payment of interest, including default
interest, on any Note;

     (4) waive a Default or Event of Default in the payment of principal of, or premium or
Additional Interest, if any, or interest on, the Notes (except a rescission of acceleration
of the Notes by the Holders of at least a majority in aggregate principal

-101-

 

amount of the then
outstanding Notes and a waiver of the payment default that resulted from such acceleration);

     (5) make any Note payable in money other than that stated in the Notes;

     (6) make any change in the provisions of this Indenture relating to waivers of past
Defaults or impair the rights of Holders to receive payments of principal of, or interest or
premium or Additional Interest, if any, on, the Notes;

     (7) waive a redemption payment with respect to any Note (other than a payment required
by Sections 4.10 or 4.15 hereof);

     (8) release any Guarantor that is a Significant Subsidiary from any of its obligations
under its Note Guarantee or this Indenture, except in accordance with the terms of this
Indenture;

     (9) impair the right to institute suit for the enforcement of any payment on or with
respect to the Notes or any Note Guarantees;

     (10) modify the subordination provisions of this Indenture in any manner adverse to the
Holders; or

     (11) make any change in the preceding amendment and waiver provisions.

Section 9.03 Compliance with Trust Indenture Act.

          Every amendment, supplement or waiver to this Indenture or the Notes will be set forth in an
amended or supplemental indenture that complies with the TIA as then in effect.

Section 9.04 Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a
Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of
the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation
before the date the amendment, supplement or waiver becomes effective. After an amendment,
supplement or waiver becomes effective in accordance with its terms, it thereafter binds every
Holder.

Section 9.05 Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment, supplement or waiver on any
Note and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

-102-

 

          Failure to make the appropriate notation or issue a new Note will not affect the validity and
effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, Etc.

          The Trustee will sign any amended or supplemental indenture authorized pursuant to this
Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until
the Board of Directors of the Company approves it. In executing any amended or supplemental
indenture, the Trustee will be provided with and (subject to Section 7.01 hereof) will be fully
protected in relying upon, in addition to the documents required by Section 13.04 hereof, an
Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or
supplemental indenture is authorized or permitted by this Indenture and that such amendment or
supplement is the legal, valid and binding obligation of the Company and the Guarantors,
enforceable against them in accordance with the its terms, subject to customary exceptions, and
complies with the provisions hereof (including Section 9.03).

ARTICLE 10

SUBORDINATION

Section 10.01 Agreement to Subordinate.

          The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness
evidenced by the Notes is subordinated in right of payment, to the extent and in the manner
provided in this Article 10, to the prior payment in full in cash or Cash Equivalents of all
Obligations due in respect of existing and future Senior Indebtedness. In addition, until all
Obligations due with respect to Senior Indebtedness are paid in full in cash or Cash Equivalents
(including, with respect to Senior Indebtedness, any interest accruing after the commencement of
any proceeding described in Section 10.02 at the rate specified in the applicable Designated Senior
Indebtedness, whether or not interest is an allowed claim enforceable against the Company in such
proceeding), any such distribution to which Holders would be entitled shall be made to the holders
of Senior Indebtedness (except that Holders may receive and retain Permitted Junior Securities and
payments made from any trust described under Articles 8 or 12 hereof).

Section 10.02 Liquidation; Dissolution; Bankruptcy.

          The holders of Senior Indebtedness shall be entitled to receive payment in full in cash or
Cash Equivalents of all Obligations due in respect of Senior Indebtedness (including with respect
to Designated Senior Indebtedness, any interest accruing after the commencement of any proceeding
described in this Section 10.02 at the rate specified in the applicable Designated Senior
Indebtedness whether or not interest is an allowed claim enforceable against the Company in such
proceeding) before the Holders shall be entitled to receive any payment on account of Senior
Subordinated Obligations or any payment to acquire any of the Notes for cash, properties or
securities, or any distribution with respect to the Notes of any cash, property, or securities
(except that Holders may receive and retain Permitted Junior Securities and payments made from

-103-

 

any trust described under Articles 8 and 12 hereof), in the event of any distribution to
creditors of the Company in (a) any liquidation or dissolution of the Company; (b) a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the Company or its
property; (c) an assignment for the benefit of its creditors; or (d) any marshaling of the
Company’s assets and liabilities.

Section 10.03 Default on Designated Senior Indebtedness.

     (a) The Company shall not make any payment in respect of any Senior Subordinated Obligations
(except in Permitted Junior Securities or from any trust described under Articles 8 and 12 hereof)
if:

     (i) a payment default on Designated Senior Indebtedness occurs and is continuing; or

     (ii) any other default (a “non-payment default”) occurs and is continuing on any series
of Designated Senior Indebtedness that permits holders of that series of Designated Senior
Indebtedness to accelerate its maturity and a Responsible Officer of the Trustee receives
actual notice of such default (a “Payment Blockage Notice”) from the trustee or other
representative for the holders of any Designated Senior Indebtedness, or the holders of at
least a majority of the outstanding principal amount of such Designated Senior Indebtedness.

     (b) Payments on the Notes may and shall be resumed:

     (i) in the case of a payment default in respect of Designated Senior Indebtedness, upon
the date on which such default is cured or waived; and

     (ii) in the case of a non-payment default in respect of Designated Senior Indebtedness,
upon the earlier of (x) the date on which such non-payment default is cured or waived or (y)
179 days after the date on which the applicable Payment Blockage Notice is received.

No new Payment Blockage Notice may be delivered unless and until 360 days have elapsed since the
delivery of the immediately prior Payment Blockage Notice and all scheduled payments of principal,
interest and premium and Additional Interest, if any, on the Notes that have come due have been
paid in full in cash.

          (c) No non-payment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment
Blockage Notice.

          (d) If the Trustee or any Holder receives a payment in respect of the Notes (except in
Permitted Junior Securities or from the trust described under Articles 8 or 12 hereof) when (i) the
payment is prohibited by this Article 10 and (ii) the Trustee or the Holder has actual knowledge
that the payment is prohibited, the Trustee or the Holder, as the case may be, shall
hold the payment in trust for the benefit of the holders of Senior Indebtedness. Upon the
proper written request of the holders of Senior Indebtedness, the Trustee or the Holder, as the
case may

-104-

 

be, shall deliver the amounts in trust to the holders of Senior Indebtedness or their
proper representative.

Section 10.04 Acceleration of Notes.

          If payment of the Notes is accelerated because of an Event of Default, the Company shall
promptly notify holders of Senior Indebtedness and the Trustee shall promptly notify the Bank Agent
of the acceleration.

Section 10.05 When Distribution Must Be Paid Over.

          In the event that the Trustee or any Holder receives any payment in respect of the Notes
(except in Permitted Junior Securities or from any trust described under Articles 8 or 12 hereof)
when (x) the payment is prohibited by this Article 10 and (y) a Responsible Officer of the Trustee
or such Holder, as applicable, has actual knowledge that such payment is prohibited by this Article
10, such payment shall be held by the Trustee or such Holder, as applicable, in trust for the
benefit of, and shall be paid forthwith over and delivered, upon written request, to the holders of
Senior Indebtedness as their interests may appear or their representative.

          With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform only
such obligations on the part of the Trustee as are specifically set forth in this Article 10, and
no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary
duty to the holders of Senior Indebtedness, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company or any other Person
money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this
Article 10, except if such payment is made as a result of the willful misconduct or gross
negligence of the Trustee.

Section 10.06 Notice by the Company.

     The Company shall promptly notify the Trustee and the Paying Agent in writing of any facts
known to the Company that would cause a payment of any Obligations with respect to the Notes to
violate this Article 10, but failure to give such notice shall not affect the subordination of the
Notes to the Senior Indebtedness as provided in this Article 10.

Section 10.07 Subrogation.

     After all Senior Indebtedness is paid in full and until the Notes are paid in full, Holders
shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Notes) to
the rights of holders of Senior Indebtedness to receive distributions applicable to Senior
Indebtedness to the extent that distributions otherwise payable to the Holders have been applied to
the payment of Senior Indebtedness. A distribution made under this Article 10 to holders of Senior
Indebtedness that otherwise would have been made to Holders is not, as between the Company and
Holders, a payment by the Company on the Notes.

-105-

 

Section 10.08 Relative Rights.

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

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

     (ii) affect the relative rights of Holders of Notes and creditors of the Company other
than their rights in relation to holders of Senior Indebtedness; or

     (iii) prevent the Trustee or any Holder of Notes from exercising its available remedies
upon a Default or Event of Default, subject to the rights of holders and owners of Senior
Indebtedness to receive distributions and payments otherwise payable to Holders.

          If the Company fails because of this Article 10 to pay principal of or interest on a Note on
the due date, the failure is still a Default or Event of Default.

Section 10.09 Subordination May Not Be Impaired by the Company.

          No right of any holder of Senior Indebtedness to enforce the subordination of the Indebtedness
evidenced by the Notes shall be impaired by any act or failure to act by the Company or any Holder
or by the failure of the Company or any Holder to comply with this Indenture.

Section 10.10 Rights of Trustee and Paying Agent.

          Notwithstanding this Article 10 or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts that would prohibit the making of any
payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make
payments on the Notes, unless the Trustee shall have received at its Corporate Trust Office at
least two Business Days prior to the date of such payment written notice of facts
that would cause the payment of any Obligations with respect to the Notes to violate this
Article 10. Only the Company may give the notice. Nothing in this Article 10 shall impair the
claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.

          The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same
rights it would have if it were not Trustee. Any Agent may do the same with like rights.

Section 10.11 Authorization to Effect Subordination.

          Each Holder, by the Holder’s acceptance of the Notes, authorizes and directs the Trustee on
such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the
subordination as provided in this Article 10, and appoints the Trustee to act as such Holder’s
attorney-in-fact for any and all such purposes. If the Trustee does not file a proper

-106-

 

proof of
claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at
least 30 days before the expiration of the time to file such claim, the lenders under the Credit
Agreement are hereby authorized to file an appropriate claim for and on behalf of the Holders.

ARTICLE 11

NOTE GUARANTEES

Section 11.01 Guarantee.

          (a) Subject to this Article 11, each of the Guarantors hereby, jointly and severally,
unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and
to the Trustee and its successors and assigns, irrespective of the validity and enforceability of
this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

     (1) the principal of, premium and Additional Interest, if any, and interest on, the
Notes will be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of and interest on the Notes,
if any, if lawful, and all other obligations of the Company to the Holders or the Trustee
hereunder or thereunder will be promptly paid in full or performed, all in accordance with
the terms hereof and thereof; and

     (2) in case of any extension of time of payment or renewal of any Notes or any of such
other obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated maturity, by
acceleration or otherwise.

          Failing payment when due of any amount so guaranteed or any performance so guaranteed for
whatever reason, the Guarantors will be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of
collection.

          (b) The Guarantors hereby agree that their obligations hereunder are unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with
respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the Company, protest,
notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged
except by complete performance of the obligations contained in the Notes and this Indenture.

          (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Company, the Guarantors or any custodian, trustee, liquidator or other similar official

-107-

 

acting in
relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such
Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force
and effect.

          (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation
to the Holders in respect of any obligations guaranteed hereby until payment in full of all
obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on
the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes
of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any
declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations
(whether or not due and payable) will forthwith become due and payable by the Guarantors for the
purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any
non-paying Guarantor so long as the exercise of such right does not impair the rights of the
Holders under the Note Guarantee.

Section 11.02 Limitation on Guarantor Liability.

          Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the
intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any
Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors
hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum
amount that will, after giving effect to such maximum amount and all
other contingent and fixed liabilities of such Guarantor that are relevant under such laws,
and after giving effect to any collections from, rights to receive contribution from or payments
made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor
under this Article 11, result in the obligations of such Guarantor under its Note Guarantee not
constituting a fraudulent transfer or conveyance.

Section 11.03 Intentionally Omitted.

Section 11.04 Guarantors May Consolidate, Etc., on Certain Terms.

          Except as otherwise provided in this Section 11.04, no Guarantor may sell or otherwise dispose
of all or substantially all of its assets to, or consolidate with or merge with or into (whether or
not such Guarantor is the surviving Person) another Person, other than the Company or another
Guarantor, unless:

     (1) immediately after giving effect to such transaction, no Default or Event of Default
exists; and

     (2) either:

          (a) the Person acquiring the property in any such sale or disposition or the
Person formed by or surviving any such consolidation or merger assumes all

-108-

 

the
obligations of that Guarantor under this Indenture, its Note Guarantee and the
Registration Rights Agreement on the terms set forth herein or therein, pursuant to
a supplemental indenture in the form attached hereto as Exhibit E; or

          (b) in the case of any such sale or disposition (including by way of any such
consolidation or merger), the Net Proceeds of such sale or other disposition are
applied in accordance with the applicable provisions of this Indenture.

          In case of any such consolidation, merger, sale or conveyance and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the Trustee, of the Note
Guarantee and the due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Guarantor, such successor Person will succeed to and be
substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.
All the Note Guarantees so issued will in all respects have the same legal rank and benefit under
this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all of such Note Guarantees had been issued at the date of the
execution hereof.

          Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b)
above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or
merger of a Guarantor with or into the Company or another Guarantor, or will
prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially
as an entirety to the Company or another Guarantor.

Section 11.05 Releases.

The Note Guarantee of a Guarantor will be released:

     (1) in connection with any sale, disposition or transfer of all or substantially all of
the assets of that Guarantor (including by way of merger or consolidation) to a Person that
is not (either before or after giving effect to such transaction) the Company or a
Restricted Subsidiary of the Company, if the sale, disposition or transfer does not violate
the first paragraph of Section 4.10 hereof;

     (2) in connection with any sale, disposition or transfer of the Capital Stock of that
Guarantor to a Person that is not (either before or after giving effect to such transaction)
the Company or a Restricted Subsidiary of the Company, if (x) after giving effect to such
sale, disposition or transfer, such Person is no longer a Subsidiary of the Company and (y)
the sale, disposition or transfer does not violate the first paragraph of Section 4.10
hereof;

     (3) if the Company designates any Restricted Subsidiary that is a Guarantor to be an
Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

     (4) upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and
discharge of this Indenture in accordance with Article 12 hereof; or

-109-

 

     (5) upon the release of such Guarantor’s guarantee under the Credit Agreement or such
other Indebtedness requiring such Guarantor to provide a Note Guarantee as provided in
Section 4.17 hereof.

          Any Guarantor not released from its obligations under its Note Guarantee as provided in this
Section 11.05 will remain liable for the full amount of principal of and interest and premium and
Additional Interest, if any, on the Notes and for the other obligations of any Guarantor under this
Indenture as provided in this Article 11.

Section 11.06 Subordination of Note Guarantee

          Payments under the Note Guarantees shall be subordinated to the prior payment in full of all
Senior Indebtedness of such Guarantor, including Senior Indebtedness incurred after the date of
this Indenture, on the same basis as the payments by the Company on the Notes are subordinated to
the prior payment in full of Senior Indebtedness of the Company. For the purposes of the foregoing
sentence, the Trustee and the Holders shall have the right to receive and/or retain payments by any
of the Guarantors only at such times as they may receive and/or retain payments in respect of the
Notes pursuant to this Indenture, including Article 10.

ARTICLE 12

SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

          This Indenture will be discharged and will cease to be of further effect as to all Notes
issued hereunder, when:

          (1) either:

          (a) all Notes that have been authenticated, except lost, stolen or destroyed
Notes that have been replaced or paid and Notes 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, have been delivered to the Trustee for
cancellation; or

          (b) all Notes that have not been delivered to the Trustee for cancellation have
become due and payable by reason of the mailing of a notice of redemption or
otherwise or will become due and payable within one year by the mailing of a notice
of redemption or otherwise, and the Company or any Guarantor has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust solely
for the benefit of the Holders, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, without
consideration of any reinvestment of interest, to pay and discharge the entire
Indebtedness (including all principal, premium and

-110-

 

          Additional Interest, if any, and
accrued interest to the date of maturity or redemption) on the Notes not delivered
to the Trustee for cancellation;

          (2) no Default or Event of Default shall have occurred and be continuing on the date of
such deposit or shall occur as a result of such deposit and such deposit will not result in
a breach or violation of, or constitute a default under, any other instrument to which the
Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other
than due to the borrowing of funds to effect such deposit);

          (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it
under this Indenture; and

          (4) the Company has delivered irrevocable instructions to the Trustee under this
Indenture to apply the deposited money toward the payment of the Notes at maturity or on the
redemption date, as the case may be.

In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the
Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

          Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited
with the Trustee pursuant to subclause (b) of clause (1) of this Section 12.01, the provisions of
Sections 12.02 and 8.06 hereof will survive such satisfaction and discharge. In addition, nothing
in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by
their terms, survive the satisfaction and discharge of this Indenture.

Section 12.02 Application of Trust Money.

          Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee
pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and
interest for whose payment such money has been deposited with the Trustee; but such money need not
be segregated from other funds except to the extent required by law.

          If the Trustee or Paying Agent is unable to apply any money or Government Securities in
accordance with Section 12.01 hereof 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 and any Guarantor’s obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof;
provided that if the Company has made any payment of principal of, premium or Additional Interest,
if any, or interest on, any Notes because of the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Notes to receive such payment from the
money or Government Securities held by the Trustee or Paying Agent.

[Reverse of Note]

91/8% Senior Subordinated Notes due 2015

          Capitalized terms used herein have the meanings assigned to them in the Indenture referred to
below unless otherwise indicated.

          (1) INTEREST. Chart Industries, Inc., a Delaware corporation (the “Company”), promises to pay
interest on the principal amount of this Note at 91/8% per annum from October 17, 2005 until maturity
and shall pay the Additional Interest, if any, payable pursuant to Section 8 of the Registration
Rights Agreement referred to below. The Company will pay interest and Additional Interest, if any,
semi-annually in arrears on April 15 and October 15 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on
the Notes will accrue from the most recent date to which interest has been paid or, if no interest
has been paid, from October 17, 2005 until the principal hereof is due. The first Interest Payment
Date shall be April 15, 2006. The Company will pay interest on overdue principal at the rate borne
by the Notes, and it shall pay interest on overdue installments of interest at the same rate to the
extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

          (2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest)
and Additional Interest, if any, to the Persons who are registered Holders of Notes at the close of
business on the April 1 or October 1 next preceding the Interest Payment Date, even if such Notes
are canceled after such record date and on or before such Interest Payment Date, except as provided
in Section 2.12 of the Indenture with respect to defaulted interest. If a Holder has given wire
transfer instructions to the Paying Agent on behalf of the Company, the Paying Agent will remit all
principal, interest and premium and Additional Interest, if any, on that Holder’s Notes in
accordance with these instructions. All other payments on the Notes will be made by mailing a
check to the registered address of each Holder thereof. Such payment will be in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts.

          (3) PAYING AGENT AND REGISTRAR. Initially, The Bank of New York, as the Trustee, will act as
Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to
any Holder. The Company or any of its Subsidiaries may act in any such capacity.

          (4) INDENTURE. The Company issued the Notes under an Indenture dated as of October 17, 2005
(the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by reference to the TIA.
Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the
Indenture. The Notes are subject to all the terms and provisions of the Indenture, and Holders are
referred to the Indenture and the TIA for a statement of such terms. To the extent any provision
of this Note conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling.

A-5

 

          The Notes are unsecured senior subordinated obligations of the Company. This Note is one of
the Initial Notes referred to in the Indenture. The Notes include the Initial Notes, any
Additional Notes and any Exchange Notes issued in exchange for Initial Notes or Additional Notes
pursuant to the Indenture. The Initial Notes, any Additional Notes and any Exchange Notes are
treated as a single class of securities under the Indenture. The Indenture imposes certain
limitations on the ability of the Company 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 the Company
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 Notes and all
other amounts payable by the Company under the Indenture and the Notes when and as the same shall
be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of
the Notes and the Indenture, the Guarantors have, jointly and severally, unconditionally guaranteed
the Obligations of the Company under the Notes on an unsecured senior subordinated basis pursuant
to the terms of the Indenture.

          (5) SUBORDINATION. The Notes and the Note Guarantees are general senior subordinated
unsecured obligations of the Company and the Guarantors, subordinated in right of payment to the
prior payment in full, in cash or Cash Equivalents, of all Obligations due in respect of existing
or future Senior Indebtedness of the Company or a Guarantor, as applicable, as set forth in
Articles 10 and 11, respectively, of the Indenture. Each Holder by its acceptance hereof agrees to
be bound by such provisions and authorizes and expressly directs the Trustee, on its behalf, to
take such action as may be necessary or appropriate to effectuate the subordination provided for in
the Indenture and appoints the Trustee its attorney-in-fact for such purposes.

          (6) OPTIONAL REDEMPTION.

          (a) Except as set forth in subparagraphs (b) and (c) of this Paragraph 6, the Company will not
have the option to redeem the Notes prior to October 15, 2010. On or after October 15, 2010, the
Company may redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice,
at the redemption prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest and Additional Interest, if any, on the Notes to be redeemed to, but
not including, the applicable redemption date, if redeemed during the twelve-month period beginning
on October 15 of the years indicated below, subject to the rights of Holders on the relevant record
date to receive interest on the relevant interest payment date:

A-6

 

	 	 	 	 	 
	Year	 	Percentage
	2010

	 	 	104.563	%
	2011

	 	 	103.042	%
	2012

	 	 	101.521	%
	2013 and thereafter

	 	 	100.000	%

          Unless the Company defaults in the payment of the redemption price, interest will cease to
accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

          (b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 6, at any time prior
to October 15, 2008, the Company may on any one or more occasions redeem up to 35% of the aggregate
principal amount of Notes issued under the Indenture (including any Additional Notes issued after
the Issue Date) at a redemption price of 109.125% of the principal amount thereof, plus accrued and
unpaid interest and Additional Interest, if any, to, but not including the redemption date, with
the net cash proceeds of one or more Equity Offerings; provided that (1) at least 65% in aggregate
principal amount of the Notes issued under the Indenture (excluding Notes held by the Company and
its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and (2)
that such redemption occurs within 180 days of the date of the closing of such Equity Offering.

          (c) At any time prior to October 15, 2010, the Company may also redeem all or a part of the
Notes, 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 Notes
to be redeemed, plus the Applicable Premium as of, and accrued and unpaid interest and Additional
Interest, if any, to, but not including, the date of redemption, subject to the rights of Holders
on the relevant record date to receive interest due on the relevant interest payment date.

          (7) MANDATORY REDEMPTION. The Company is not required to make mandatory redemption or sinking
fund payments with respect to the Notes.

          (8) 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 whose Notes are to be
redeemed at its registered address, except that redemption notices may be mailed more than 60 days
prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or
a satisfaction or discharge of the Indenture. Notes in denominations larger than $1,000 may be
redeemed in part but only in whole multiples of $1,000. Unless the Company defaults in the payment
of the redemption price, interest will cease to accrue on the Notes or portions thereof called for
redemption on the applicable redemption date.

          (9) REPURCHASE AT THE OPTION OF HOLDER.

          (a) If there is a Change of Control, the Company will make an offer (a “Change of Control
Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an

A-7

 

integral multiple of $1,000) of that Holder’s Notes at a purchase price in cash equal to 101%
of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and
Additional Interest, if any, on the Notes repurchased to, but not including, the date of purchase,
subject to the rights of Holders on the relevant record date to receive interest due on the
relevant interest payment date. Within 30 days following any Change of Control, the Company will
mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as
required by the Indenture.

          (b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales,
within ten Business Days of each date on which the aggregate amount of Excess Proceeds exceeds
$15.0 million, the Company will make an offer to all Holders of Notes and all holders of other
Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in
the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an
"Asset Sale Offer”) pursuant to Section 4.10 of the Indenture to purchase the maximum principal
amount of Notes and such other pari passu Indebtedness 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 and Additional Interest, if any, thereon to, but excluding, the date of
purchase, in accordance with the procedures set forth in the Indenture. To the extent that, any
Excess Proceeds remain after the consummation of an Asset Sale Offer, the Company may use those
Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu
Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an
offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase
date and may elect to have such Notes purchased by completing the form entitled “Option of Holder
to Elect Purchase” attached to the Notes.

          (10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered
and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require
a Holder, among other things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note
selected for redemption, except for the unredeemed portion of any Note being redeemed in part.
Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record date and the
corresponding Interest Payment Date.

          (11) PERSONS DEEMED OWNERS. The registered Holder of a Note shall be treated as its owner for
all purposes.

          (12) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the
Notes or the Note Guarantees may be amended or supplemented with the consent of the Company and
Holders of at least a majority in aggregate principal amount of the then outstanding Notes,
including Additional Notes, if any, voting as a single

A-8

 

class, and any existing Default or Event or Default or compliance with any provision of the
Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Notes, including Additional Notes,
if any, voting as a single class. Without the consent of any Holder of a Note, the Indenture or
the Notes or the Note Guarantees may be amended or supplemented (i) to cure any ambiguity, defect
or inconsistency, (ii) to provide for uncertificated Notes in addition to or in place of
certificated Notes, (iii) to provide for the assumption of the Company’s or a Guarantor’s
obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation or
sale of all or substantially all of the Company’s or such Guarantor’s assets, as applicable, (iv)
to make any change that would provide any additional rights or benefits to the Holders or that does
not adversely affect the legal rights under the Indenture of any such Holder, (v) to comply with
the requirements of the SEC in order to effect or maintain the qualification of the Indenture under
the TIA, (vi) to conform the text of the Indenture, the Note Guarantees or the Notes to any
provision of the “Description of the Notes” section of the Company’s Offering Memorandum dated
September 30, 2005, to the extent that such provision in that “Description of the Notes” was
intended to be a verbatim recitation of a provision of the Indenture, the Note Guarantees or the
Notes, (vii) to provide for the issuance of Additional Notes in accordance with the limitations set
forth in the Indenture; (viii) to allow any Guarantor to execute a supplemental indenture to the
Indenture and/or a Note Guarantee with respect to the Notes and to release Guarantors from the Note
Guarantee in accordance with the terms of the Indenture; (ix) to comply with the rules of any
applicable securities depositary; or (x) to provide for a successor Trustee in accordance with the
terms of the Indenture or to otherwise comply with any requirement of the Indenture.

          (13) DEFAULTS AND REMEDIES. If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare
all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an
Event of Default arising from certain events of bankruptcy or insolvency with respect to the
Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of
Restricted Subsidiaries of the Company that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes will become due and payable immediately without further action or
notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in aggregate principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power. The Holders of a
majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may,
on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default
or Event of Default and its consequences under the Indenture except a continuing Default or Event
of Default in the payment of interest or premium or Additional Interest, if any, on, or the
principal of, the Notes. The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required, upon becoming aware of any
Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event
of Default.

          (14) DISCHARGE AND DEFEASANCE. Subject to certain conditions, the Company at any time may
terminate some or all of its obligations under the Notes, the Note Guarantees and the Indenture if
the Company deposits with the Trustee money or Government Securities for the payment of principal
of and interest on the Notes to redemption or maturity, as the case may be.

A-9

 

          (15) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may
make loans to, accept deposits from, and perform services for the Company or its Affiliates, and
may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

          (16) NO RECOURSE AGAINST OTHERS. No past, present or future director, manager, officer,
employee, incorporator, stockholder or member of the Company, any Parent or any Subsidiary, as
such, will have any liability for any obligations of the Company or the Guarantors under the Notes,
the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Notes.

          (17) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature
of the Trustee or an authenticating agent.

convenience to Holders. No representation is made as to the accuracy of such numbers either as
printed on the Notes or as contained in any notice of redemption, and reliance may be placed only
on the other identification numbers placed thereon.

WITNESSETH

          WHEREAS, the Company and the existing Guarantors have heretofore executed and delivered to the
Trustee an indenture (as amended, supplemented or otherwise modified, the “Indenture”), dated as of
October 17, 2005 providing for the issuance of
91/8% Senior Subordinated Notes due 2015 (the
“Notes”);

          WHEREAS, Section 4.17 of the Indenture provides that under certain circumstances the New
Guarantor shall execute and deliver to the Trustee a supplemental indenture pursuant to which the
New Guarantor shall unconditionally guarantee all of the Company’s Obligations under the Notes and
the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

          WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee, the Company and the existing
Guarantors are authorized to execute and deliver this Supplemental Indenture.

          NOW, THEREFORE, in consideration of the foregoing and for other good and valuable
consideration, the receipt of which is hereby acknowledged, the New Guarantor, the Company and the
Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes
as follows:

          1. DEFINED TERMS. Defined terms used herein without definition shall have the meanings
assigned to them in the Indenture.

          2. AGREEMENT TO GUARANTEE. The New Guarantor hereby agrees, jointly and severally with all
existing Guarantors (if any), to provide an unconditional guarantee on the terms and subject to the
conditions set forth in Article 11 of the Indenture and to be bound by all other applicable
provisions of the Indenture, including the provisions relating the subordination of such guarantee
set forth in Article 10, and the Notes and to perform all of the obligations and agreements of a
Guarantor under the Indenture.

          3. NO RECOURSE AGAINST OTHERS. No past, present or future director, manager, officer,
employee, incorporator, stockholder or member of the Company, any parent entity of the Company or

creation. Each Holder by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for issuance of the Notes. The waiver may not be
effective to waive liabilities under the federal securities laws.

provided in Section 13.02 of the Indenture.

          5. RATIFICATION OF INDENTURE; SUPPLEMENTAL INDENTURES PART OF INDENTURE. Except as expressly
amended hereby, the Indenture is in all respects ratified and confirmed and all the terms,
conditions and provisions thereof shall remain in full force and effect. This Supplemental

or hereafter authenticated and delivered shall be bound hereby.

          6. GOVERNING LAW. THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

          7. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture.
Each signed copy shall be an original, but all of them together represent the same agreement.

          8. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not
