with respect to the Notes. If any term or provision contained in this Supplemental

 

 

Indenture shall conflict or be inconsistent with any term or provision of the Base Indenture,
the terms and provisions of this Supplemental Indenture shall govern with respect to the Notes.
For all purposes of this Supplemental Indenture, except as otherwise expressly provided or unless

such period (including amortization of original issue discount and bond premium, the
interest component of Capital Lease Obligations, and net payments and receipts (if any)
pursuant to interest rate Hedging Obligations (provided, however, that if interest rate
Hedging Obligations result in net benefits rather than costs, such benefits shall be
credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such net benefits
are otherwise reflected in Consolidated Net Income) and excluding amortization of deferred
financing fees, debt issuance costs, commissions, fees and expenses and expensing of any
financing fees); plus

     (2) consolidated capitalized interest of such Person and the Restricted Subsidiaries
for such period, whether paid or accrued; minus

Net Income of such Person and its Restricted Subsidiaries determined in accordance with GAAP;
provided, however, that there will not be included in such Consolidated Net Income:

that subject to the limitations contained in clauses (2) and (3) below, the Company’s equity in the

to the aggregate amount of cash actually distributed by such Person during such period to the
Company or a Restricted Subsidiary as a dividend or other distribution;

     (2) Net Income or loss of any Person for any period prior to the acquisition of such Person by

     “Fixed Charge Coverage Ratio” means with respect to any specified Person for any period, the
ratio of the Consolidated Cash Flow of such Person and its Restricted Subsidiaries for such period
to the Fixed Charges of such Person and its Restricted Subsidiaries for such period. In the event
that the specified Person or any of its Restricted Subsidiaries incurs, assumes, guarantees,
repays, repurchases or redeems any Indebtedness (other than ordinary working

11

 

capital borrowings) or issues, repurchases or redeems Disqualified Stock or preferred stock
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 or redemption of Indebtedness, or such issuance, repurchase or redemption of
Disqualified Stock or preferred stock, and the use of the proceeds therefrom as if the same had
occurred at the beginning of the applicable four-quarter reference period. For purposes of
calculating the Fixed Charge Coverage Ratio, the Existing Convertible Senior Notes shall be deemed
to be retired on the Issue Date.

related financing transactions, during the four-quarter reference period or subsequent to such

     (2) the Fixed Charges attributable to discontinued operations, as determined in accordance
with GAAP, and operations or businesses disposed of prior to the Calculation Date, will be
excluded, but only to the extent that the obligations giving rise to such Fixed Charges will not be
obligations of the specified Person or any of its Restricted Subsidiaries following the Calculation
Date.

     For purposes of this definition, whenever pro forma effect is to be given to an Investment,
acquisition, disposition, merger or consolidation and the amount of income or earnings relating
thereto, the pro forma calculations shall be determined in good faith by a responsible financial or
accounting officer of the Company and such pro forma calculations may include operating expense
reductions for such period resulting from the transaction which is being given pro forma effect
that (A) have been realized or (B) for which the steps necessary for realization have been taken

realization are reasonably expected to be taken within the twelve-month period following such
transaction and, in each case, including, but not limited to, (a) reduction in personnel expenses,
(b) reduction of costs related to administrative functions, (c) reduction of costs related to

adjustment or adjustments, (ii) in the case of items (B) or (C) above, that such adjustment or
adjustments are based on the reasonable good faith belief of the officer executing such Officer’s
Certificate at the time of such execution and (iii) that any related incurrence of Indebtedness is
permitted pursuant to this Supplemental Indenture. 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 the related hedge
has a remaining term in excess of twelve months).

12

 

     Interest on a Capital Lease Obligation shall be deemed to accrue at the 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.

also include a depository receipt issued by a bank (as defined in Section 3(a)(2) of the Securities
Act) as custodian with respect to any such Government Securities or a specific payment of principal
of or interest on any such Government Securities held by such custodian for the account of the
holder of such depository receipt; provided, however, that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to the holder of such

includes all Indebtedness of others secured by a Lien on any asset of the specified Person (whether
or not such Indebtedness is assumed by the specified Person), provided, however, that

14

 

the amount of such Indebtedness will be the lesser of (a) the Fair Market Value of such asset at
such date of determination and (b) the amount of such Indebtedness of such other Person and, to the
extent not otherwise included, the Guarantee by the specified Person of any Indebtedness of any
other Person. For the avoidance of doubt, Permitted Warrant Transactions shall not constitute
“Indebtedness”.

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

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

held under escrow arrangements in the ordinary course of business.

Notwithstanding anything in this Supplemental Indenture to the contrary, Indebtedness shall not
include, and shall be calculated without giving effect to, the effects of ASC 815 and related
interpretations to the extent such effects would otherwise increase or decrease an amount of
Indebtedness for any purpose under this Supplemental Indenture as a result of accounting for any
embedded derivatives created by the terms of such Indebtedness; and any such amounts that would
have constituted Indebtedness under this Supplemental Indenture but for the application of this

of the

15

 

Company sells or otherwise disposes of any Equity Interests of any direct or indirect
Subsidiary of the Company such that, after giving effect to any such sale or disposition, such
Person is no longer a Subsidiary of the Company, the Company will be deemed to have made an
Investment on the date of any such sale or disposition equal to the Fair Market Value of the Equity
Interests of such Subsidiary not sold or disposed of in an amount determined as provided in Section
4.03(c) hereof. The acquisition by the Company or any Subsidiary of the Company of a Person that
holds an Investment in a third Person will be deemed to be an Investment by the Company or such

by the acquired Person in such third Person in an amount determined as provided in Section 4.03(c)
hereof. Except as otherwise provided in this Supplemental Indenture, the amount of an Investment

Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of the Indenture.

Section 2.03 Notes in Global Form.

     Notes issued as a Global Note shall represent such of the outstanding Notes as shall be
specified therein and may provide that it shall represent the aggregate principal amount of
outstanding Notes from time to time endorsed thereon or otherwise notated on the books and records
of the Registrar 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 aggregate principal amount of any
increase or decrease in the amount of outstanding Notes represented thereby shall be made by the
Trustee in such manner and upon instructions given by the Holder thereof.

     Global Notes may be issued in either registered or bearer form and in either temporary or
permanent form. Permanent Global Notes will be issued in definitive form.

31

 

     The provisions of the last sentence of Section 2.02 hereof shall apply to any Note represented
by a Global Note if such Note was never issued and sold by the Company, and the Company delivers to
the Trustee the Note in global form together with written instructions with regard to the reduction
in the principal amount of Notes represented thereby, together with the written statement
contemplated by the last sentence of Section 2.02 hereof.

     Notwithstanding the provisions of this Section 2.03 and Section 2.14 hereof, payment of
principal of and any interest on any Global Note shall be made to the person or persons specified
therein.

     None of the Company, the Trustee, any Paying Agent or Registrar will have any responsibility
or liability for any aspect of the records relating to or payments made on account of beneficial
ownership interests of a Global Note or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

Section 2.04 Amount of Notes.

     On the Issue Date, the Trustee shall authenticate and deliver $400,000,000 aggregate principal
amount of 7.50% Senior Notes due November 15, 2019 and, at any time and from time to time
thereafter, the Trustee shall authenticate and deliver Notes for original issue in an aggregate
principal amount specified in a Company Order. Such order shall specify the amount of the Notes to
be authenticated and the date on which the original issue of Notes is to be authenticated and, in
the case of an issuance of Additional Notes pursuant to Section 2.16 hereof after the Issue Date,
shall certify that such issuance is in compliance with Section 4.02 hereof. The aggregate
principal amount of Notes which may be authenticated and delivered under this Supplemental
Indenture is unlimited, subject to compliance with Section 4.02 hereof. The Notes may have
notations, legends or endorsements required by law, stock exchange rules or usage. The Notes shall
be in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000.

     All Notes shall be substantially identical except as to the date from which interest shall
accrue and except as may otherwise be provided in any indenture supplemental hereto.

     If any of the terms of the Notes are established by action taken pursuant to a Board
Resolution, a copy of any appropriate record of such action shall be certified by the Secretary or
an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of
the Officer’s Certificate setting forth the terms of the Notes.

     The Notes, including any Additional Notes, shall be treated as a single class for all purposes
under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to
purchase.

Section 2.05 Registrar and Paying Agent.

     The Company shall maintain, with respect to the Notes, 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”) in the Borough of Manhattan, the City of New
York. The Registrar shall keep a register (the “Note Register”) of

32

 

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 shall notify the
Trustee in writing of the name and address of any Agent not a party to the Indenture. If the
Company fails to appoint or maintain another entity as Registrar of Paying Agent, the Trustee shall
act as such. The Company or any of its Restricted Subsidiaries may act as Paying Agent or
Registrar.

     The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with
respect to the Global Notes.

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

Section 2.06 Paying Agent to Hold Money in Trust.

     The Company shall 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 of, premium, 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 funds held by it relating to
the Notes to the Trustee. The Company at any time may require a Paying Agent to pay all funds held
by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Company or a Restricted Subsidiary) shall have no further liability for such funds. If the Company
or a Restricted Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all funds held by it as Paying Agent. Upon any Event of
Default under Sections 6.01(i) and (j) hereof relating to the Company, the Trustee shall serve as
Paying Agent for the Notes.

Section 2.07 Holder Lists.

     The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of all Holders and shall otherwise comply with TIA
§312(a). If the Trustee is not the Registrar, the Company shall furnish or cause to be furnished
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 and the Company shall otherwise
comply with TIA §312(a).

Section 2.08 Registration; Registration of Transfer and Exchange.

     Upon surrender for registration of transfer of any Notes at an office or agency of the Company
designated pursuant to Section 2.05 hereof or Section 3.2 of the Base Indenture for such purpose,
the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Notes of any authorized denominations, of a
like aggregate principal amount. The Company shall not charge a service

33

 

charge for any registration of transfer or exchange, but the Company may require payment of a
sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in
connection with the transfer or exchange of the Notes from the Holder requesting such transfer or
exchange (other than any exchange of a temporary Note for a permanent Note not involving any change
in ownership or any exchange pursuant to Sections 2.12 or 3.06 hereof, not involving any transfer).

     Notwithstanding any other provisions (other than the provisions set forth in the fourth
paragraph) of this Section 2.08 hereof, a Global Note representing all or a portion of the Notes
may not be transferred except as a whole by the Depositary to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such Depositary or by such
Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

     Each Global Note is exchangeable for Notes in certificated form only if (i) the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary for such Global Notes
or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act
and the Company fails within 90 days thereafter to appoint a successor Depositary, (ii) the Company
in its sole discretion determines that such Global Note shall be exchangeable or (iii) there shall
have occurred and be continuing a Default with respect to the Notes represented by such Global
Notes. In any such event the Company will issue, and the Trustee, upon receipt of a Company Order
for the authentication and delivery of certificated Notes, will authenticate and deliver Notes in
certificated form in exchange for such Global Note. In any such instance, an owner of a beneficial
interest in either Global Note will be entitled to physical delivery in certificated form of Notes
equal in principal amount to such beneficial interest and to have such Notes registered in its
name. Notes so issued in certificated form will be issued in denominations of $2,000 or any larger
amount that is an integral multiple of $1,000, and will be issued in registered form only, without
coupons.

     Upon the exchange of a Global Note for Notes in certificated form, such Global Note shall be
cancelled by the Trustee. All cancelled Notes held by the Trustee shall be disposed of by the
Trustee and, upon written request by the Company, a certificate of their disposal delivered to the
Company. Definitive Notes issued in exchange for a Global Note pursuant to this Section 2.08 shall
be registered in such names and in such authorized denominations as the Depositary for such Note in
global form, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee in writing. The Trustee shall deliver such Notes as instructed in writing by
the Depositary.

     At the option of the Holders of certificated Notes, certificated Notes may be exchanged for
other certificated Notes of any authorized denomination or denominations of like aggregate
principal amount and tenor, upon surrender of the certificated Notes to be exchanged at such office
or agency. Whenever any certificated Notes are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the certificated Notes which the Holder
making the exchange is entitled to receive.

34

 

     All Notes issued upon any registration of transfer or exchange of Notes shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under the
Indenture, as the Notes surrendered upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or for exchange shall be duly
endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company
and the Registrar duly executed, by the Holder thereof or his or her attorney duly authorized in
writing.

     The Company shall not be required (i) to issue, register the transfer of or exchange any Notes
during a period beginning 15 Business Days before any selection of Notes to be redeemed and ending
at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to
register the transfer of or exchange any Note so selected for redemption, in whole or in part,
except the unredeemed portion of any Note being redeemed in part.

Section 2.09 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 shall issue
and, upon receipt of a Company Order, the Trustee shall authenticate a replacement Note. If
required by the Trustee or the Company, the Holder of such Note shall provide indemnity that is
sufficient, in the judgment of the Trustee or the Company, to protect the Company, the Trustee, any
Agent and any authenticating agent from any loss that any of them may suffer in connection with
such replacement. If required by the Company, such Holder shall reimburse the Company for its
reasonable expenses in connection with such replacement.

     Every replacement Note issued in accordance with this Section 2.09 shall be the valid
obligation of the Company, evidencing the same debt as the destroyed, lost or stolen Note, and
shall be entitled to all of the benefits of the Indenture equally and proportionately with all
other Notes duly issued hereunder.

Section 2.10 Outstanding Notes.

     The Notes outstanding at any time shall be the entire principal amount of Notes represented by
all of the Global Notes and Definitive Notes authenticated by the Trustee except for those
cancelled by it, those delivered to it for cancellation, those subject to reductions in beneficial
interests effected by the Trustee in accordance with the provisions hereof, and those described in
this Section 2.10 as not outstanding. Except as set forth in Section 2.11 hereof, a Note shall not
cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

     If a Note is replaced pursuant to Section 2.09 hereof, it shall cease to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide
purchaser.

     If the principal amount of any Note is considered paid under Section 3.1 of the Base
Indenture, it shall cease to be outstanding and interest on it shall cease to accrue.

35

 

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a Redemption Date, a Purchase Date or a maturity date, funds sufficient to pay Notes
payable on that date, then on and after that date such Notes shall be deemed to be no longer
outstanding and shall cease to accrue interest.

Section 2.11 Treasury Notes.

     In determining whether the Holders of the required principal amount of Notes have concurred in
any direction, waiver or consent, Notes owned by the Company, or by any Affiliate of the Company,
shall be disregarded and deemed not to be outstanding, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, waiver or consent, only
Notes that a Responsible Officer of the Trustee knows are so owned shall be so disregarded.

Section 2.12 Temporary Notes.

     Until certificates representing Notes are ready for delivery, the Company may prepare and,
upon receipt of a Company Order in accordance with Section 2.02 hereof, the Trustee shall
authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive
Notes but may have variations that the Company considers appropriate for temporary Notes and as
shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate Global Notes or Definitive Notes in exchange for
temporary Notes, as applicable. After preparation of Definitive Notes, the Temporary Note will be
exchangeable for Definitive Notes upon surrender of the Temporary Notes.

     Holders of temporary Notes shall be entitled to all of the benefits of the Indenture as
Holders of permanent Notes.

Section 2.13 Cancellation.

     The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and
Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for
registration of transfer, exchange, payment, replacement or cancellation and shall dispose of
cancelled Notes (subject to the record retention requirement of the Exchange Act or other
applicable laws) unless by written order, signed by an Officer of the Company, the Company directs
them to be returned to it.

     Certification of the disposal of all cancelled Notes shall be delivered to the Company from
time to time upon request. The Company may not issue new Notes to replace Notes that it has paid
or that have been delivered to the Trustee for cancellation.

Section 2.14 Payment of Interest; Defaulted Interest.

     Interest on any Note which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the person in whose name that Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record Date for such
interest.

36

 

     If the Company defaults in a payment of interest on the Notes which is payable (“Defaulted
Interest”), it shall 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. The Company shall notify the Trustee
in writing of the amount of Defaulted Interest proposed to be paid on each Notes and the date of
the proposed payment. The Company shall fix or cause to be fixed each such Special Record Date and
payment date, provided that no such Special Record Date shall 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) shall mail or cause to be mailed to Holders a notice that states the
Special Record Date, the related payment date and the amount of such interest to be paid.

     Subject to the foregoing provisions of this Section 2.14 and Section 2.08 hereof, each Note
delivered under the Indenture upon registration of transfer of or in exchange for or in lieu of any
other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried
by such other Note.

Section 2.15 CUSIP or ISIN Numbers.

     The Company in issuing the Notes may use “CUSIP” and/or “ISIN” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” and/or “ISIN” numbers in notices of redemption or
Offers to Purchase as a convenience to Holders; provided, however, that neither the Company nor the
Trustee shall have any responsibility for any defect in such “CUSIP” or “ISIN” numbers that appear
on any such notice and 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 or notice of an Offer to Purchase and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption or Offer to Purchase shall not
be affected by any defect in or omission of such numbers. The Company shall promptly notify the
Trustee if it becomes aware of any change in the “CUSIP” and/or “ISIN” numbers.

Section 2.16 Additional Notes.

     The Company shall be entitled, subject to its compliance with Section 4.02 hereof, to issue an
unlimited amount of Additional Notes under the Indenture which shall have identical terms as the
Initial Notes issued on the date hereof, other than with respect to the date of issuance and issue
price. The Initial Notes issued on the date hereof and any Additional Notes shall be treated as a
single class for all purposes under the Indenture, including directions, waivers, amendments,
consents, redemptions and Offers to Purchase.

     With respect to any Additional Notes, the Company shall set forth in a Board Resolution and an
Officer’s Certificate, a copy of each of which shall be delivered to the Trustee, the following
information:

     (a) the aggregate principal amount of such Additional Notes to be authenticated and delivered
pursuant to the Indenture; and

37

 

     (b) the issue price, the Issue Date and the CUSIP and/or ISIN number of such Additional Notes.

Section 2.17 Record Date.

     The record date for purposes of determining the identity of Holders of Notes entitled to vote
or consent to any action by vote or consent or permitted under the Indenture shall be determined as
provided for in TIA §316(c).

Section 2.18 Persons Deemed Owners.

     Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the person in whose name such Note is registered
as the owner of such Note for the purpose of receiving payment of principal of and (except as
otherwise specified as contemplated by the first paragraph of Section 2.04 hereof and subject to
Sections 2.07 and 2.13 hereof) interest on such Note and for all other purposes whatsoever, whether
or not such Note be overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

     None of the Company, the Trustee, any Paying Agent or the Registrar will have any
responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Note in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

Section 2.19 Computation of Interest.

     Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve
30-day months.

ARTICLE 3.

REDEMPTION AND PREPAYMENT

     Article 12 of the Base Indenture shall be superseded in its entirety by this Article 3 with
respect to, and solely for the benefit of the holders of, the Notes, provided that this Article 3
shall not become a part of the terms of any other series of Securities.

Section 3.01 Notices to Trustee.

     Except as set forth in Paragraph 5 of the form of the Notes set forth in Exhibit A,
the Company will not be entitled to redeem the Notes at its option prior to the Stated Maturity of
the Notes.

     If the Company elects to redeem Notes, it shall furnish to the Trustee, at least 30 days (or
such shorter period as may be acceptable to the Trustee) but not more than 60 days before a
Redemption Date, an Officer’s Certificate setting forth (a) the applicable section of this
Supplemental Indenture and the Note pursuant to which the redemption shall occur, (b) the

38

 

Redemption Date, (c) the principal amount of Notes to be redeemed and (d) the Redemption

Section 3.02 Selection of Notes to Be Redeemed.

     If less than all of the Notes are to be redeemed at any time, the Trustee shall select the
Notes to be redeemed among the Holders of the Notes in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed or, if the Notes are
not so listed, based on a method that most nearly approximates a pro rata basis, unless otherwise
required by law or depository requirements. In the event of partial redemption, the particular
Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the Redemption Date by the Trustee from the outstanding Notes not previously
called for redemption.

     The Trustee shall promptly notify the Company in writing of the Notes selected for redemption
and, in the case of any Note selected for partial redemption, the principal amount thereof to be
redeemed. No Notes of $2,000 or less shall be redeemed in part. Notes and portions of Notes
selected shall be in amounts of $2,000 or integral multiples of $1,000 in excess of $2,000; except
that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes
held by such Holder, even if not an integral multiple of $1,000, shall be redeemed. Except as
provided in the two preceding sentences, provisions of this Supplemental 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 prior to a Redemption Date, the Company shall mail
or cause to be mailed, by electronic transmission (for Notes held in book entry form) or first
class mail, a notice of redemption to each Holder whose Notes are to be redeemed at such Holder’s
registered address appearing in the Note Register, 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 pursuant to Article 8 hereof or a satisfaction and discharge pursuant to Article 11
hereof.

     The notice shall identify the Notes to be redeemed and shall state:

     (a) the Redemption Date;

     (b) the appropriate method for calculation of the Redemption Price, but need not include the
Redemption Price itself; the actual Redemption Price shall be set forth in an Officer’s Certificate
delivered to the Trustee no later than two (2) Business Days prior to the Redemption Date.

     (c) 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, if applicable, a new
Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation
of the original Note;

39

 

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

     (e) that Notes called for redemption must be surrendered to the Paying Agent to collect the
Redemption Price;

     (f) that, unless the Company defaults in making such redemption payment, interest on Notes
called for redemption ceases to accrue on and after the Redemption Date;

for redemption are being redeemed; and

     (h) that no representation is made as to the correctness of the CUSIP and/or ISIN numbers, if
any, listed in such notice or printed on the Notes.

     At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at its expense; provided, however, that the Company shall have delivered to the Trustee,
at least 45 days (or such shorter period allowed by the Trustee), prior to the Redemption Date, an
Officer’s Certificate requesting that the Trustee give such notice (in the name and at the expense
of the Company) 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, subject to the
satisfaction or waiver of any conditions precedent as provided for in the next sentence, Notes
called for redemption shall become irrevocably due and payable on the Redemption Date at the
Redemption Price. Notice of any redemption may, at the Company’s discretion, be subject to one or
more conditions precedent.

Section 3.05 Deposit of Redemption Price.

     On or prior to 11:00 a.m. Eastern time on any Redemption Date, the Company shall deposit with
the Trustee or with the Paying Agent (or, if the Company or any of its Restricted Subsidiaries is
the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price
of and, if applicable, accrued and unpaid interest on all Notes to be redeemed on that date. The
Trustee or the Paying Agent shall promptly, and in any event within two (2) Business Days after the
Redemption Date, 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 and
unpaid interest, if any, on, all Notes to be redeemed.

     If the Company complies with the provisions of the preceding paragraph, unless the Company
defaults in the payment of the Redemption Price, interest shall cease to accrue on the Notes or the
portions of Notes called for purchase or redemption on the applicable Redemption Date. If a Note
is redeemed on or after a Regular Record Date but on or prior to the related Interest Payment Date,
then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such Note
was registered at the close of business on such Regular Record Date. If any Note called for
redemption shall not be 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

40

 

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.

Section 3.06 Notes Redeemed in Part.

     Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon receipt
of a Company Order in accordance with Section 2.02 hereof, the Trustee shall authenticate for the
Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion
of the Note surrendered.

Section 3.07 Mandatory Redemption

     The Company shall not be required to make mandatory redemption or sinking fund payments with
respect to the Notes. The Company and its Subsidiaries may at any time and from time to time
purchase Notes in open market transactions, tender offers or otherwise.

     (a) In the event that, pursuant to Sections 4.05 or 4.09 hereof, the Company shall be required
to commence an Asset Sale Offer or a Change of Control Offer (each, an “Offer to Purchase”), it
shall follow the procedures specified below.

     (b) The Company shall commence the Offer to Purchase by sending, by first-class mail (or
electronic transmission), with a copy to the Trustee, to each Holder at such Holder’s address
appearing in the Note Register, a notice the terms of which shall govern the Offer to Purchase
stating:

     (1) that the Offer to Purchase is being made pursuant to this Section 3.08 and Sections
4.05 or 4.09 hereof, as the case may be, and, in the case of a Change of Control Offer, that

of Control and that a Change of Control Offer is being made pursuant to Section 4.09 hereof;

     (2) the principal amount of Notes required to be purchased pursuant to Sections 4.05 or
4.09 hereof, as the case may be (the “Offer Amount”), the purchase price set forth in
Sections 4.05 or 4.09 hereof, as applicable (the “Purchase Price”), the Offer Period and the

     (3) except as provided in clause (9), that all Notes timely tendered and not withdrawn
shall be accepted for payment;

     (4) that any Note not tendered or accepted for payment shall continue to accrue
interest;

     (5) that, unless the Company defaults in making such payment, any Note accepted for
payment pursuant to the Offer to Purchase shall cease to accrue interest after the Purchase
Date;

41

 

     (6) that Holders electing to have a Note purchased pursuant to an Offer to Purchase may
elect to have Notes purchased equal to $2,000 or in integral multiples of $1,000 in excess
of $2,000 only;

     (7) that Holders electing to have a Note purchased pursuant to any Offer to Purchase
shall be required to surrender the Note, with the form entitled “Option of Holder to Elect
Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the
Company, the Depositary, if appointed by the Company, or a Paying Agent at the address
specified in the notice before the close of business on the third Business Day before the
Purchase Date;

     (8) that Holders shall be entitled to withdraw their election if the Company, the
Depositary or the Paying Agent, as the case may be, receives, not later than the expiration
of the Offer Period, a telegram, facsimile transmission or letter setting forth the name of
the Holder, the principal amount of the Note (or portions thereof) the Holder delivered for
purchase and a statement that such Holder is withdrawing his election to have such Note
purchased;

     (9) that, in the case of an Asset Sale Offer, if the aggregate principal amount of
Notes surrendered by Holders exceeds the Offer Amount, the Company shall select the Notes to
be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the
Company so that only Notes in denominations of $2,000 or integral multiples of $1,000 in
excess of $2,000 shall be purchased); and

     (10) that Holders whose Notes were purchased in part shall be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered (or transferred by

(the “Purchase Date”), the Company shall purchase the Offer Amount or, if less than the Offer
Amount has been tendered, all Notes tendered in response to the Offer to Purchase. Payment for any
Notes so purchased shall be made in the same manner as interest payments are made.

     (d) On or prior to the Purchase Date, the Company shall, to the extent lawful:

     (1) accept for payment (on a pro rata basis to the extent necessary in connection with
an Asset Sale Offer), the Offer Amount of Notes or portions of Notes properly tendered and
not withdrawn pursuant to the Offer to Purchase, or if less than the Offer Amount has been
tendered, all Notes tendered;

     (2) deposit with the Paying Agent funds in an amount equal to the Purchase Price in
respect of all Notes or portions of Notes properly tendered; and

42

 

     (3) deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officer’s Certificate stating the aggregate principal amount of Notes or
portions of Notes being purchased by the Company and that such Notes or portions thereof
were accepted for payment by the Company in accordance with the terms of this Section 3.08.

     (e) The Paying Agent (or the Company, if acting as the Paying Agent) shall promptly (but in
the case of a Change of Control, not later than 60 days from the date of the Change of Control)
deliver to each tendering Holder the Purchase Price. In the event that any portion of the Notes
surrendered is not purchased by the Company, the Company shall promptly execute and issue a new
Note in a principal amount equal to such unpurchased portion of the Note surrendered, and, upon
receipt of a Company Order in accordance with Section 2.02 hereof, the Trustee shall authenticate
and deliver (or cause to be transferred by book-entry) such new Note to such Holder, (it being
understood that, notwithstanding anything in this Supplemental Indenture or the Base Indenture to
the contrary, no Opinion of Counsel or Officer’s Certificate is required for the Trustee to
authenticate and deliver (or cause to be transferred by book-entry) such new Note), in a principal
amount equal to any unpurchased portion of the Note surrendered; provided, however, that each such
new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of
$2,000. Any Note not so accepted shall be promptly mailed or delivered by the Company to the
Holder thereof.

     (f) If the Purchase Date is on or after a Regular Record Date and on or before the related
Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a
Note is registered at the close of business on such Regular Record Date.

     (g) The Company shall comply, to the extent applicable, 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 Offer to Purchase. To the extent that
the provisions of any securities laws or regulations conflict with Sections 4.05 or 4.09 hereof, as
applicable, this Section 3.08 or other provisions of the Indenture, the Company shall comply with
applicable securities laws and regulations and shall not be deemed to have breached its obligations
under Sections 4.05 or 4.09 hereof, as applicable, this Section 3.08 or such other provision by
virtue of such compliance.

     Other than as specifically provided in this Section 3.08, any purchase pursuant to this
Section 3.08 shall be made in accordance with the provisions of Sections 3.01 through 3.06 hereof.

ARTICLE 4.

Section 4.01 SEC Reports.

     (a) Notwithstanding that the Company may not be subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, so long as the Notes are outstanding the Company will file
with the SEC (unless the SEC will not accept such filing) and provide the Trustee within 15 days
after the filing of the same, such annual and quarterly reports and such information, documents and
other reports specified in Sections 13 and 15(d) of the Exchange Act within the time periods
specified in the SEC’s rules and regulations; provided, however, that if the Company shall not be

shall be provided at the times specified in the SEC’s rules and regulations for a registrant that
is a non-accelerated filer, plus any grace period provided by Rule 12b-25 under the Exchange Act.
the Company will be deemed to have furnished such reports referred to in this section to the
Trustee and the Holders of the Notes if the Company has filed such reports with the SEC via the
EDGAR filing system or posted such reports on its website.

     (b) Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officer’s Certificates).

Section 4.02 Incurrence of Indebtedness and Issuance of Preferred Stock.

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly
liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness
(including Acquired Debt), and the Company will not issue any Disqualified Stock and will not
permit any of its Restricted Subsidiaries to issue any shares of preferred stock (including
Disqualified Stock) other than to the Company; provided, however, that the Company may incur
Indebtedness (including Acquired Debt) or issue Disqualified Stock and any Guarantor may incur
Indebtedness (including Acquired Debt) or issue preferred stock (including Disqualified Stock), if
the 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 preferred stock or Disqualified Stock is issued 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
preferred stock or Disqualified Stock had been issued, as the case may be, at the beginning of such
four-quarter period.

     (b) Section 4.02(a) hereof will not prohibit the incurrence of any of the following items of
Indebtedness (collectively, “Permitted Debt”):

Indebtedness, and letters of credit under one or more Credit Facilities; provided that the
aggregate principal amount of all Indebtedness and letters of credit of the Company and any
Restricted Subsidiary incurred pursuant to this clause (1) (with letters of credit being
deemed to have a principal amount equal to the face amount thereof) does not exceed the

44

 

greater of (a) $500.0 million and (b) 20.0% of Consolidated Total Assets (less the
aggregate principal amount of Indebtedness incurred by Securitization Subsidiaries and then
outstanding pursuant to clause (14));

     (2) the incurrence by the Company and any of the Restricted Subsidiaries of Existing

construction or improvement of property, plant or equipment used in the business of the
Company or such Restricted Subsidiary, in an aggregate principal amount, including all
Permitted Refinancing Indebtedness, Disqualified Stock and preferred stock incurred to
refund, refinance or replace any Indebtedness, Disqualified Stock and preferred stock
incurred pursuant to this clause (4), not to exceed the greater of (a) $62.5 million or (b)
2.5% of Consolidated Total Assets at any time outstanding;

     (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 serve to extend,
defease, renew, refund, refinance or replace Indebtedness (other than intercompany
Indebtedness) that was incurred under Section 4.02(a) hereof or clauses (2) (other than with
respect to the Existing Convertible Senior Notes), (3), (4), this clause (5), (13) or (18)
of this Section 4.02(b);

     (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 (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 and (ii) any subsequent sale or other transfer of any such Indebtedness to a
Person that is not either the Company or a Restricted Subsidiary 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);

     (7) the incurrence of Indebtedness of the Company or any of its Restricted Subsidiaries
consisting of guarantees, indemnities, holdbacks or obligations in respect of purchase price
adjustments in connection with the acquisition or disposition of assets, including, without
limitation, shares of Capital Stock of Restricted Subsidiaries or contingent payment
obligations incurred in connection with the acquisition of assets which are contingent on
the performance of the assets acquired, other than guarantees of Indebtedness incurred by
any Person acquiring all or any portion of such assets or shares of Capital Stock of such
Restricted Subsidiary for the purpose of financing such acquisition;

45

 

     (8) the incurrence of Indebtedness of the Company or any of its Restricted
Subsidiaries in respect of bid, appeal, surety and performance bonds, completion guarantees

requirements in the ordinary course of business or in respect of awards or judgments not
resulting in an Event of Default;

     (9) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
arising from the honoring by a bank or other financial institution of a check, draft or
similar instrument inadvertently drawn against insufficient funds, so long as such
Indebtedness is covered within 10 business days or arising in connection with endorsement of
instruments for deposit in the ordinary course of business;

employees and directors of the Company or any of its Restricted Subsidiaries incurred in the
ordinary course of business;

     (11) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging
Obligations; provided that such Hedging Obligations are entered into for bona fide hedging
purposes (and not for speculative purposes) of the Company or its Restricted Subsidiaries
(as determined in good faith by the Board of Directors or an Officer of the Company);

     (12) the Guarantee by the Company or any of the Restricted Subsidiaries of Indebtedness
of the Company or a Restricted Subsidiary that was permitted to be incurred by another
provision of this Section 4.02; provided that if the Indebtedness being guaranteed is
incurred by the Company and is subordinated to the Notes, then the Guarantee of such
Indebtedness by any of its Restricted Subsidiaries shall be subordinated to the same extent
as the Indebtedness guaranteed;

     (13) Indebtedness of a Restricted Subsidiary outstanding on the date on which such
Restricted Subsidiary was acquired by the Company or otherwise became a Restricted
Subsidiary (other than Indebtedness incurred as consideration in, or to provide all or any
portion of the funds or credit support utilized to consummate, the transaction or series of
transactions pursuant to which such Restricted Subsidiary became a subsidiary of the Company
or was otherwise acquired by the Company), provided that after giving effect thereto, (a)
the Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant
to the Fixed Charge Coverage Ratio test set forth in Section 4.02(a) hereof, or (b) the
Fixed Charge Coverage Ratio would be no worse than immediately prior thereto;

     (14) Indebtedness incurred by a Securitization Subsidiary in connection with a
Qualified Securitization Transaction that is not recourse with respect to the Company and
its Restricted Subsidiaries (other than pursuant to Standard Securitization Undertakings or
Limited Originator Recourse); provided, however, that in the event such Securitization
Subsidiary ceases to qualify as a Securitization Subsidiary or such Indebtedness becomes
recourse to the Company or any of its Restricted Subsidiaries (other than pursuant to

46

 

Standard Securitization Undertaking or Limited Originator Recourse), such Indebtedness
will, in each case, be deemed to be, and must be classified by the Company as, incurred at
such time (or at the time initially incurred) under one more of the other provisions of this
Section 4.02;

     (15) the incurrence by the Company or any Restricted Subsidiary of Indebtedness to the
extent the proceeds thereof are used to purchase Notes pursuant to a Change of Control Offer
or to defease or discharge Notes in accordance with the terms of this Supplemental
Indenture;

     (16) the incurrence by the Company or any Restricted Subsidiary of Indebtedness
consisting of (a) the financing of insurance premiums or (b) take or pay obligations in
supply agreements, in each case in the ordinary course of business;

     (17) Indebtedness in respect of secured or unsecured letters of credit incurred by the
Company or any Restricted Subsidiary in an aggregate principal amount not to exceed the
greater of (a) $100.0 million or (b) 4.0% of Consolidated Total Assets;

     (18) Contribution Indebtedness;

     (19) the incurrence by the Company or any Restricted Subsidiary of Indebtedness on
behalf of or representing Guarantees of any Permitted Joint Venture not to exceed the
greater of (a) $50.0 million or (b) 2.0% of Consolidated Total Assets;

consisting of obligations to make payments to current or former directors, officers,
employees or consultants, their respective Affiliates, heirs and executors with respect to
the cancellation, purchase or redemption of, Capital Stock of the Company or its Restricted
Subsidiaries to the extent permitted under Section 4.03(b)(4) hereof; and

     (21) the incurrence by the Company or any of its Restricted Subsidiaries of additional
Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time
outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance
or replace any Indebtedness incurred pursuant to this clause (21), not to exceed the greater
of (a) $125.0 million or (b) 5.0% of Consolidated Total Assets.

     (c) For purposes of determining compliance with this Section 4.02, in the event that an item
of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described
in clauses (1) through (21) of Section 4.02(b) hereof or is entitled to be incurred pursuant to
Section 4.02(a) hereof, the Company shall, in its sole discretion, classify (or later re-classify
in whole or in part), or divide (or later re-divide in whole or in part) such item of Indebtedness
(or any portion thereof) in any manner that complies with this Section 4.02 and such Indebtedness
will be treated as having been incurred pursuant to such clauses or Section 4.02(a) hereof, as the
case may be, designated by the Company . Accrual of interest or dividends, the accretion of
accreted value or liquidation preference and the payment of interest or dividends in the form of
additional Indebtedness or Disqualified Stock will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.02.

47

 

     (d) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement
governing such Indebtedness) is subordinated to any other Indebtedness of the Company or such
Restricted Subsidiary, as the case may be, unless made expressly subordinate to the Notes to the
same extent and in the same manner as such Indebtedness is subordinated pursuant to subordination
provisions that are most favorable to the Holders of any other Indebtedness of the Company or such
Restricted Subsidiary, as the case may be.

Section 4.03 Restricted Payments.

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly:

     (1) declare or pay any dividend or make any other payment or distribution (A) on
account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including,
without limitation, any payment in connection with any merger or consolidation involving the
Company or any of its Restricted Subsidiaries) or (B) to the direct or indirect holders of
the Company’s or any Restricted Subsidiaries’ Equity Interests in their capacity as such
(other than dividends, payments or distributions (i) payable in Equity Interests (other than
Disqualified Stock) of the Company or (ii) to the Company or a wholly owned Restricted
Subsidiary or to all holders of Capital Stock of a Restricted Subsidiary on a pro rata
basis);

     (2) purchase, redeem or otherwise acquire or retire for value (including, without
limitation, in connection with any merger or consolidation involving the Company) any Equity
Interests of the Company or any of its Restricted Subsidiaries (other than (a) Equity
Interests of any wholly-owned Restricted Subsidiary of the Company or (b) purchases,
redemptions, defeasances or other acquisitions made by a Restricted Subsidiary on a pro rata
basis from all shareholders of such Restricted Subsidiary);

     (3) make any payment on or with respect to, or purchase, redeem, defease or otherwise
acquire or retire for value any Subordinated Obligations (excluding any intercompany
Indebtedness between or among the Company or any of its Restricted Subsidiaries), except a
payment of interest or principal at the Stated Maturity thereof or the payment, purchase,
redemption, defeasance or other acquisition or retirement for value of any such Subordinated
Obligations, in each case where the Stated Maturity is within one year of such payment,
purchase, redemption, defeasance or other acquisition or retirement for value; or

     (4) make any Restricted Investment (all such payments and other actions set forth in
these clauses (1) through (4) above being collectively referred to as “Restricted
Payments”),

unless, at the time of and after giving effect to such Restricted Payment:

     (A) no Default or Event of Default has occurred and is continuing or would
occur as a consequence thereof;

48

 

     (B) the Company would, at the time of such Restricted Payment and after giving
pro forma effect thereto as if such Restricted Payment had been made at the
beginning of the applicable four-quarter period, have been permitted to incur at
least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in Section 4.02(a) hereof; and

     (C) such Restricted Payment, together with the aggregate amount of all other
Restricted Payments made by the Company and the Restricted Subsidiaries after the
Issue Date (excluding Restricted Payments permitted by clauses (b)(2), (3), (4),
(5), (6), (7), (10), (11) and (12) of this Section 4.03), is less than the sum,
without duplication, of:

     (I) 50% of the Consolidated Net Income of the Company for the period
(taken as one accounting period) from the beginning of the first full fiscal
quarter during which the Issue Date falls to the end of the Company’s most
recently ended fiscal quarter for which internal financial statements are
available at the time of such Restricted Payment (or, if such Consolidated
Net Income for such period is a deficit, less 100% of such deficit), plus

     (II) 100% of the aggregate net cash proceeds (or the Fair Market Value
of property other than cash) received by the Company since the Issue Date as
a contribution to its common equity capital or from the issuance or sale of
Equity Interests of the Company (other than the issuance of Disqualified
Stock or any Permitted Warrant Transaction) or from the issuance or sale of
convertible or exchangeable Disqualified Stock or convertible or
exchangeable debt securities of the Company, in either case, that have been
converted into or exchanged for such Equity Interests of the Company (other
than Equity Interests or Disqualified Stock or debt securities sold to a
Subsidiary of the Company), plus

     (III) to the extent that any Restricted Investment that was made after
the Issue Date is (a) sold for cash or otherwise cancelled, liquidated or
repaid for cash, the cash proceeds received with respect to such Restricted
Investment (less the cost of disposition, if any) or (b) made in an entity
that subsequently becomes a Restricted Subsidiary, an amount equal to the
Fair Market Value of the Restricted Investments owned by the Company and the
Restricted Subsidiaries in such entity at the time such entity becomes a
Restricted Subsidiary, plus

     (IV) 100% of the aggregate net cash proceeds (or the Fair Market Value
of property other than cash) received by the Company since the
Issue Date by means of (a) the sale (other than to the Company or
a Restricted Subsidiary) of the Capital Stock of an Unrestricted Subsidiary
and (B) a distribution or dividend from an Unrestricted Subsidiary (other
than in each case to the extent such Investment constituted a Permitted

49

 

Investment), in each case to the extent that such amounts were not otherwise
included in the Consolidated Net Income for such period, plus

     (V) in case, after the date hereof, any Unrestricted Subsidiary has
been redesignated as a Restricted Subsidiary under the terms of this
Supplemental Indenture or has been merged, consolidated or amalgamated with
or into, or transfers or conveys assets to, or is liquidated into the
Company or a Restricted Subsidiary, an amount equal to the Fair Market
Value of the Restricted Investments owned by the Company and the
Restricted Subsidiaries in such Unrestricted Subsidiary at the time of the
redesignation, combination or transfer (or of the assets transferred or
conveyed, as applicable).

     (b) Notwithstanding any of the foregoing, and in the cases of clauses (6) and (12) below, so
long as no Default or Event of Default has occurred and is continuing or would be caused thereby,
the preceding provisions will not prohibit:

     (1) the payment of any dividend within 60 days after the date of declaration of the
dividend, if at the date of declaration the dividend payment would have complied with the
provisions of this Supplemental Indenture;

     (2) any Restricted Payments made out of the net cash proceeds of the substantially
concurrent sale (other than to a Restricted Subsidiary of the Company) of, Equity Interests
of the Company (other than Disqualified Stock); provided, however, that the amount of any
such net cash proceeds from such sale will be excluded from Section 4.03(a)(4)(C)(II)
hereof;

     (3) the redemption, repurchase, repayment, retirement, defeasance or other acquisition
of any Subordinated Obligations with the net cash proceeds from an incurrence of Permitted
Refinancing Indebtedness;

     (4) the redemption, repurchase or other acquisition or retirement for value of any
Equity Interests of the Company or any Restricted Subsidiary of the Company (a) held by any
current or former director, officer, employee or consultant of the Company or any of its
Restricted Subsidiaries and their Affiliates, heirs and executors pursuant to any management
equity subscription plan or agreement, stock option or stock purchase plan or agreement or
employee benefit plan as may be adopted by the Company or any of its Restricted Subsidiaries
from time to time or pursuant to any agreement with any director, officer, employee or
consultant of the Company or any of its Restricted Subsidiaries in existence on the Issue
Date or (b) from an employee of the Company or any of its Restricted Subsidiaries upon the
termination of such employee’s employment with the Company or any of its Restricted
Subsidiaries; provided, however, that the aggregate price paid for all such repurchased,
redeemed, acquired or retired Equity Interests in reliance on this clause (4) (other than
with respect to employees whose employment has terminated) may not exceed $7.5 million in
any calendar year, with any unused amounts in any calendar year being carried forward to the
immediately

50

 

succeeding calendar year and provided, further, that such amount in any calendar year
may be increased by an amount not to exceed (A) the cash proceeds from the sale of Equity
Interests (other than Disqualified Stock) of the Company, in each case to members of
management, directors or consultants of the Company or any of its Subsidiaries that occurs
after the Issue Date, provided that such cash proceeds utilized for redemptions, repurchases
or other acquisitions or retirements will be excluded from Section 4.03(a)(4)(C)(II) hereof
plus (B) the cash proceeds of “key man” life insurance policies received by the Company or
its Restricted Subsidiaries after the Issue Date (provided that the Company may elect to
apply all or any portion of the aggregate increase contemplated by clauses (A) and (B) above
in any calendar year, it being understood that the forgiveness of any debt by such Person
shall not be a Restricted Payment hereunder) less (C) the amount of any Restricted Payments
previously made pursuant to clauses (A) and (B) of this clause (4);

     (5) repurchases, acquisitions or retirements of Capital Stock of the Company deemed to
occur upon the exercise or vesting of stock options, warrants or restricted stock or similar
rights under employee benefit plans of the Company or its Subsidiaries if such Capital Stock
represents all or a portion of the exercise price thereof and repurchases, acquisitions or
retirements of Capital Stock or options to purchase Capital Stock in connection with the
exercise or vesting of stock options, warrants or restricted stock to the extent necessary
to pay applicable withholding taxes;

     (6) any Restricted Payments, so long as the Total Debt Ratio is no more than 2.0 to
1.0, both as of the date thereof (based on a computation period of the twelve calendar month
period most recently ended for which internal financial statements are available) and on a
pro forma basis after giving effect to such Restricted Payment;

     (7) payments of cash, dividends, distributions advances or other Restricted Payments by
the Company or any of its Restricted Subsidiaries to allow the payment of cash in lieu of
the issuance of fractional shares in connection with the exercise of warrants, options or
other securities convertible into or exchangeable for Capital Stock of the Company;
provided, however, that any such cash payment shall not be for the purpose of evading the
limitation of the covenant described under this subheading (as determined in good faith by
the Board of Directors of the Company);

     (8) the repurchase, redemption or other acquisition or retirement for value of any
Subordinated Obligations or Disqualified Stock pursuant to provisions similar to those
described under Sections 4.05 and 4.09 hereof; provided that a Change of Control Offer or
Asset Sale Offer, as applicable, has been made and all Notes tendered by Holders in
connection with a Change of Control Offer or Asset Sale Offer, as applicable, have been
repurchased, redeemed or acquired for value;

     (9) the declaration and payment of regularly scheduled or accrued dividends or
distributions to holders of any class or series of Disqualified Stock of the Company or any
preferred stock of any Restricted Subsidiary of the Company issued on or after the Issue

definition of Fixed Charges;

51

 

     (10) the making of cash payments in connection with any conversion of Permitted
Convertible Indebtedness in an aggregate amount since the Issue Date therefor not to exceed
the sum of (a) the principal amount of such Permitted Convertible Indebtedness plus (b) any
payments received by the Company or any of its Restricted Subsidiaries pursuant to the
exercise, settlement or termination of any related Permitted Bond Hedge Transaction;

     (11) any payments in connection with (including, without limitation, the purchase of) a
Permitted Bond Hedge Transaction and the settlement of any related Permitted Warrant
Transaction (a) by delivery of shares of the Company’s common stock upon net share
settlement of such Permitted Warrant Transaction or (b) by (i) set-off of such Permitted
Warrant Transaction against the related Permitted Bond Hedge Transaction and (ii) payment of
an amount due upon termination of such Permitted Warrant Transaction in common stock or
using cash received upon the exercise, settlement or termination of a Permitted Bond Hedge
Transaction upon any early termination thereof; and

     (12) other Restricted Payments in an aggregate amount since the Issue Date not to
exceed $350.0 million.

     (c) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on
the date of the Restricted Payment of the assets, property or securities proposed to be transferred
or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the
Restricted Payment. Not later than the date of making any Restricted Payment (other than those set
forth in clauses (1) through (12) of Section 4.03(b) hereof), in the case of any Restricted Payment
in an amount greater than $25.0 million, the Company will deliver to the Trustee an Officer’s
Certificate, setting forth any Fair Market Value determinations, stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations required by this
Section 4.03 were computed. If the Company or a Restricted Subsidiary makes a Restricted Payment
which at the time of the making of such Restricted Payment would in the good faith determination of
the Company be permitted under the provisions of this Supplemental Indenture, such Restricted
Payment shall be deemed to have been made in compliance with this Supplemental Indenture
notwithstanding any subsequent adjustments made in good faith to the Company’s financial statements
affecting Consolidated Net Income of the Company for any period.

Section 4.04 Liens.

     The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur or assume any consensual Liens (the “Initial Lien”) of any kind against
or upon any of their respective properties or assets, or any proceeds, income or profit therefrom
or assign or convey any right to receive income therefrom, except Permitted Liens, to secure any
Indebtedness of the Company unless prior to, or contemporaneously therewith, the Notes are equally
and ratably secured by a Lien on such property, assets, proceeds, income or profit; provided,
however, that if such Indebtedness is expressly subordinated to the Notes, the Lien securing such
Indebtedness will be subordinated and junior to the Lien securing the Notes with the same relative
priority as such Indebtedness has with respect to the Notes. Any Lien

52

 

created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall
provide by its terms that such Lien shall be automatically and unconditionally released and
discharged upon the release and discharge of the Initial Lien.

Section 4.05 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 sold, leased, transferred, conveyed or otherwise disposed of or Equity Interests of
any Restricted Subsidiary of the Company issued, sold, transferred, conveyed 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 or Cash Equivalents. For purposes of this
clause (2), each of the following will be deemed to be cash:

     (A) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s
most recent balance sheet or in the notes thereto, of the Company or any of its
Restricted Subsidiaries (other than contingent liabilities and liabilities that are
by their terms subordinated to the Notes) (A) that are assumed by the transferee of
any such assets and from which the Company or such Restricted Subsidiary have been
validly released by all creditors in writing, or (B) in respect of which neither the
Company nor any Restricted Subsidiary following such Asset Sale has any obligation;

     (B) any securities, notes or other obligations 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 90 days, to the
extent of the cash or Cash Equivalents received in that conversion; and

     (C) any Designated Non-cash Consideration received by the Company or any of its
Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value,
taken together with all other Designated Non-cash Consideration received pursuant to
this clause (c) not to exceed 5.0% of the Consolidated Total Assets at the time of
the receipt of such Designated Non-cash Consideration (determined based on the most
recently ended fiscal quarter for which internal financial statements are available
and with the Fair Market Value of each item of Designated Non-cash Consideration
being measured at the time received and without giving effect to subsequent changes
in value) shall be deemed to be cash for purposes of this paragraph and for no other
purpose.

     To the extent that the Fair Market Value of any Asset Sale exceeds 10.0% of Consolidated Total
Assets at the time of receipt of the Net Proceeds of any such Asset Sale (determined based on the
most recently ended fiscal quarter for which internal financial

53

 

statements are then available and with the Fair Market Value of each Asset Sale being measured
at the time of such Asset Sale), then, within 365 days after the receipt of any Net Proceeds from
any such Asset Sale, the Company or such Restricted Subsidiary may apply those Net Proceeds (but
shall only be required to apply that portion of the Net Proceeds from such Asset Sale that exceeds
10.0% of Consolidated Total Assets) at its option (or any portion thereof):

     (1) to permanently repay Indebtedness of the Company or any Restricted Subsidiary that
is secured by a Lien (other than Indebtedness owed to the Company or any Affiliate of the
Company) and, if such Indebtedness repaid is revolving credit Indebtedness, to
correspondingly reduce commitments with respect thereto; or

     (2) to make an Investment in any one or more businesses (provided that if such
Investment is in the form of the acquisition of Capital Stock of a Person, such acquisition
results in such Person becoming a Restricted Subsidiary), assets, or property or capital
expenditures, in each case (a) used or useful in a Permitted Business or (b) that replace
the properties and assets that are the subject of such Asset Disposition;

provided that a binding commitment to apply Net Proceeds as set forth in clauses (1) and (2) above
shall be treated as a permitted application of the Net Proceeds from the date of such commitment so
long as the Company or such Restricted Subsidiary enters into such commitment with the good faith
expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of
such commitment (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later
cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith,
then the Company or such Restricted Subsidiary shall be permitted to apply the Net Proceeds in any
manner set forth in clauses (1) and (2) above before the expiration of such 180-day period and, in
the event the Company or such Restricted Subsidiary fails to do so, then such Net Proceeds shall
constitute Excess Proceeds (as defined below). 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 Supplemental Indenture.

     Any Net Proceeds from Asset Sales that were required to be applied in accordance with the
first sentence of the immediately preceding paragraph and that are not so applied or invested as
provided in the preceding paragraph will constitute “Excess Proceeds”. When the aggregate amount
of Excess Proceeds exceeds $25.0 million, within 30 days thereof, the Company will make an offer
(an “Asset Sale Offer”) to all Holders to purchase the maximum principal amount of Notes and, if
the Company is required to do so under the terms of any other Indebtedness that is pari passu in
right of payment with the Notes, such other Indebtedness on a pro rata basis with the Notes, that
may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal
to 100% of principal amount plus accrued and unpaid interest, if any, to, but not including, the
date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of
the purchase of all properly tendered and not withdrawn Notes pursuant to an Asset Sale Offer, the
Company may use such remaining Excess Proceeds for any purpose not otherwise prohibited by this
Supplemental 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
will select the Notes and such other pari passu Indebtedness to

54

 

be purchased on a pro rata basis. 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 Supplemental Indenture, the Company will comply with the applicable securities
laws and regulations and will not be deemed to have breached its obligations under this Section
4.05 or Section 3.08 hereof by virtue of such compliance.

Section
4.06 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

     The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or permit to exist or become effective any consensual encumbrance or restriction
on the ability of any of its Restricted Subsidiaries to:

     (a) pay dividends or make any other distributions on its Capital Stock to the Company or any
of its Restricted Subsidiaries, or with respect to any other interest or participation in, or
measured by, its profits, or pay any Indebtedness owed to the Company or any of its Restricted
Subsidiaries;

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

     (c) transfer any of its properties or assets to the Company or any of its Restricted
Subsidiaries.

     However, the preceding restrictions will not apply to encumbrances or restrictions existing
under or by reason of:

     (1) agreements governing Existing Indebtedness as in effect on the Issue Date;

     (2) this Supplemental Indenture and the Notes;

     (3) applicable law or any applicable rule, regulation or order of, or arrangement with,
any regulatory body or agency;

     (4) any agreement or other instrument of (i) a Person acquired by the Company or any of
its Restricted Subsidiaries as in effect at the time of such acquisition (except to the
extent such encumbrance or restriction was created in connection with or in contemplation of
such acquisition) or (ii) any Unrestricted Subsidiary at the time it is designated or is
deemed to become a Restricted Subsidiary, which encumbrance or restriction is not applicable
to any Person, or the properties or assets of any Person, other than the Person or
Unrestricted Subsidiary, or the property or assets of the Person or Unrestricted Subsidiary,
so acquired or designated, as the case may be;

     (5) restrictions on cash or other deposits or net worth imposed by customers or
governmental regulatory bodies or required by insurance, surety or bonding

55

 

companies, in each case pursuant to contracts entered into in the ordinary course of
business;

     (6) customary non-assignment provisions in leases, licenses, sublicenses and other
contracts entered into in the ordinary course of business;

     (7) purchase money obligations for property acquired in the ordinary course of business
and Capital Lease Obligations that impose restrictions on that property of the
nature described in clause (c) of the first paragraph of this Section 4.06;

     (8) any agreement for the sale or other disposition of a Restricted Subsidiary or the
assets of a Restricted Subsidiary pending the closing of such sale or other disposition or
the sale or other disposition of its assets;

     (9) Permitted Refinancing Indebtedness; provided, however, that the restrictions
contained in the agreements governing such Permitted Refinancing Indebtedness are not
materially more restrictive, taken as a whole, than those contained in the agreements
governing the Indebtedness being refinanced (as determined in good faith by an officer of
the Company);

     (10) Liens securing Indebtedness otherwise permitted to be incurred under the
provisions of Section 4.04 hereof that limit the right of the debtor to dispose of the
assets subject to such Liens;

     (11) provisions with respect to the disposition or distribution of assets or property
in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale
agreements, agreements in respect of Permitted Market Investments and other similar
agreements (including agreements entered into in connection with a Restricted Investment);
provided that such provisions with respect to the disposition or distribution of assets or
property relate only to the assets or properties subject to such agreements;

     (12) other Indebtedness, Disqualified Stock or preferred stock permitted to be incurred
subsequent to the Issue Date under the provisions of Section 4.02 hereof; provided that such
incurrence will not materially impair the Company’s ability to make payments under the Notes
when due (as determined in good faith by an officer of the Company);

     (13) contractual requirements of a Restricted Subsidiary in connection with a Qualified
Securitization Transaction, provided that such restrictions apply only to such Restricted
Subsidiary; and

     (14) any amendment, modification, restatement, renewal, increase, supplement,
refunding, replacement or refinancing of an agreement referred to in clauses (1) through
(13) above, provided, however that such amendment, modification, restatement, renewal,
increase, supplement, refunding, replacement or refinancing is not materially more
restrictive, taken as a whole, than those prior to such amendment, modification,
restatement, renewal, increase, supplement, refunding, replacement or refinancing (as
determined in good faith by an officer of the Company).

56

 

For purposes of determining compliance with this Section 4.06, (i) the priority of any preferred
stock in receiving dividends or liquidating distributions prior to dividends or liquidating
distributions being paid on common stock shall not be deemed a restriction on the ability to make
distributions on Capital Stock and (2) the subordination of loans or advances made to the Company
or a Restricted Subsidiary to other Indebtedness incurred by the Company or any such Restricted
Subsidiary shall not be deemed a restriction on the ability to make loans or advances.

Section 4.07 Affiliate Transactions.

     (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
(each, an “Affiliate Transaction”), unless:

     (1) the Affiliate Transaction is on terms that are not less favorable in any material
respect 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 with respect to any Affiliate Transaction or
series of related Affiliate Transactions involving aggregate consideration in excess of
$50.0 million, a resolution of the Board of Directors of the Company set forth in an
Officer’s Certificate certifying that such Affiliate Transaction complies with this Section
4.07 and that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors of the Company.

     (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will
not be subject to the provisions of clause (a) of this Section 4.07:

     (1) transactions solely between or among the Company and/or any of its Restricted
Subsidiaries or solely among its Restricted Subsidiaries;

     (2) any issuances of Equity Interests (other than Disqualified Stock) to Affiliates of
the Company;

     (3) reasonable and customary fees, indemnification and similar arrangements, consulting
fees, employee salaries, bonuses or employment or severance agreements, compensation,
employee or consultant benefit arrangements or plans and incentive arrangements or plans
(including any amendments to the foregoing) with any officer, director or employee of the
Company or a Restricted Subsidiary entered into in the ordinary course of business or
approved in good faith by the Board of Directors of the Company;

     (4) any transactions made in compliance with Section 4.03 hereof;

     (5) loans (and cancellation of loans) and advances to directors, officers, employees or
consultants of the Company or any of its Restricted Subsidiaries entered

57

 

into in the ordinary course of business in accordance with the past practices of the
Company or any of its Restricted Subsidiaries or approved in good faith by the Board of
Directors of the Company;

     (6) any agreement as in effect as of the Issue Date or any amendment thereto so long as
any such amendment is not more disadvantageous to the Holders in any material respect than
the original agreement as in effect on the Issue Date;

     (7) any transaction effected as part of a Qualified Securitization Transaction;

     (8) transactions entered into by a Person prior to the time such Person becomes a
Restricted Subsidiary or is merged or consolidated into the Company or a Restricted
Subsidiary (provided such transaction is not entered into in contemplation of such event);

     (9) transactions permitted by, and complying with, the provisions of Section 5.01
hereof;

     (10) 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 such Person; and

     (11) any transaction in which the Company or any Restricted Subsidiary, as the case may
be, receives an opinion from a nationally recognized investment banking, appraisal or
accounting firm that such Affiliate Transaction is either fair, from a financial standpoint,
to the Company or such Restricted Subsidiary or meets the requirements of Section 4.07(a)(1)
hereof.

Section 4.08 Designation of Restricted and Unrestricted Subsidiaries.

     The Company’s Board of Directors may designate any of its Restricted Subsidiaries to be an
Unrestricted Subsidiary if that designation would not cause a Default. If any of the Company’s
Restricted Subsidiaries 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
newly designated Unrestricted Subsidiary shall be deemed to be an Investment made as of the time of
that designation and will either reduce the amount available for Restricted Payments under Section
4.03(a) hereof or be a Permitted Investment, as determined by the Company. Such designation of
such a Subsidiary or Person as an Unrestricted Subsidiary will be permitted only if the deemed
Investment would be permitted at the time the Restricted Subsidiary is designated as an
Unrestricted Subsidiary and, in any case, if that Subsidiary or Person otherwise satisfies the
requirements set forth in the definition of Unrestricted Subsidiary. The Company’s Board of
Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the
redesignation would not cause a default.

Section 4.09 Repurchase at the Option of Holders Upon a Change of Control.

     (a) Upon the occurrence of a Change of Control Event, the Company shall, within 30 days of a
Change of Control Event, make an offer (the “Change of Control Offer”) pursuant to

58

 

the procedures set forth in Section 3.08 hereof. Each Holder shall have the right to accept
such offer and require the Company to repurchase all or any portion (provided that no Notes of
$2,000 or less will be repurchased in part) of such Holder’s Notes pursuant to the Change of
Control Offer at a purchase price, in cash, equal to 101% of the aggregate principal amount of
Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased, to, but not
including, the Purchase Date (subject to the rights of Holders of Notes on the relevant record date
to receive interest due on the relevant interest payout date).

     (b) The Company will not be required to make a Change of Control Offer upon a Change of
Control if (i) 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 Supplemental Indenture applicable
to a Change of Control Offer by the Company and purchases all Notes properly tendered and not
withdrawn under the Change of Control Offer or (ii) notice of redemption has been given pursuant to
the indenture as described in Section 3.03 hereof, unless and until there is a default in payment
of the applicable Redemption Price. A Change of Control Offer may be made in advance of a Change
of Control Event and may be conditional upon the occurrence of a Change of Control Event, if a
definitive agreement is in place for the Change of Control Event at the time the Change of Control
Offer is made.

Section 4.10 Limitation on Issuances of Guarantees of Indebtedness.

     The Company will not permit any of its Restricted Subsidiaries, directly or indirectly, to
guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company
unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture in
the form included in Exhibit C attached hereto providing for the guarantee of the payment
of the Notes by such Restricted Subsidiary. The Subsidiary Guarantee will be (1) senior to such
Restricted Subsidiary’s Guarantee of or pledge to secure such other Indebtedness if such other
Indebtedness is subordinated in right of payment to the Notes; or (2) pari passu in right of
payment with such Restricted Subsidiary’s Guarantee of, or pledge to secure, such other
Indebtedness if such other Indebtedness is not subordinated in right of payment to the Notes.

     The Subsidiary Guarantee of a Guarantor will be automatically and unconditionally released:

     (1) in connection with any sale or other disposition 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 subsidiary
of the Company, if the sale or other disposition does not violate Section 4.05 hereof;

     (2) in connection with any sale or other disposition of all 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 subsidiary of the Company, if the sale or other disposition
does not violate Section 4.05 hereof;

59

 

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

     (4) if such Guarantor is dissolved or liquidated;

     (5) upon legal defeasance, covenant defeasance or satisfaction and discharge of the
Notes as provided below under Sections 8.02, 8.03 and 11.01 hereof; or

     (6) if such Guarantor is released or discharged from the underlying Guarantee of
Indebtedness giving rise to the execution of a Subsidiary Guarantee.

The form of Subsidiary Guarantee is attached hereto as Exhibit B. Notwithstanding the foregoing,
if the Company guarantees Indebtedness incurred by any of the Restricted Subsidiaries, such
Guarantee by the Company will not require any of its Restricted Subsidiaries to provide a
Subsidiary Guarantee for the Notes.

Section 4.11 Covenant Termination.

     Following the first day (such date, the “Covenant Termination Date”):

     (a) the Notes have an Investment Grade Rating; and

     (b) no Default has occurred and is continuing under the Indenture;

the Company and its Restricted Subsidiaries shall cease to be subject to the provisions of:

     (1) Section 4.02 hereof;

     (2) Section 4.03 hereof;

     (3) Section 4.05 hereof

     (4) Section 4.06 hereof;

     (5) Section 4.07 hereof; and

     (6) Section 4.10 hereof

(collectively, the “Terminated Covenants”). No Default, Event of Default or breach of any kind
shall be deemed to exist under the Indenture or the Notes with respect to the Terminated Covenants
based on, and none of the Company or any of its Subsidiaries shall bear any liability for, any
actions taken or events occurring after the Notes attain an Investment Grade Rating, regardless of
whether such actions or event would have been permitted if the applicable Terminated Covenants
remained in effect. The Terminated Covenants will not be reinstated even if the Company
subsequently does not satisfy the requirements set forth in clauses (a) and (b) above. After the
Terminated Covenants have been terminated, Company and its Restricted Subsidiaries shall remain
subject to the provisions of Section 4.09 hereof and the following Sections:

60

 

          (1) Section 4.01 hereof;

          (2) Section 4.04 hereof (other than the definition of “Permitted Liens” which shall
be replaced as set forth in the paragraph below); and

          (3) Section 5.01 hereof (other than the financial test set forth in clause (a)(4)
thereof).

     On the Covenant Termination Date, the definition of “Permitted Liens” set forth in Section
1.01 hereof shall be replaced in its entirety with the following definition:

“Permitted Liens” means:

     (1) Liens in favor of the Company or the Restricted Subsidiaries;

     (2) Liens on any property or assets of a Person existing at the time such Person is
merged with or into or consolidated with the Company or any Restricted Subsidiary of the
Company; provided that such Liens were in existence prior to such merger or consolidation
and not incurred in contemplation thereof and do not extend to any property or assets other
than those of the Person merged into and consolidated with the Company or the Restricted
Subsidiary;

     (3) Liens for taxes or other governmental charges not at the time delinquent or
thereafter payable without penalty or being contested in good faith by appropriate
proceedings and, in each case, for which it maintains adequate reserves;

     (4) Liens on any property or assets existing at the time of the acquisition thereof by
the Company or any Restricted Subsidiary of the Company; provided that such Liens were in
existence prior to the contemplation of such acquisition and do not extend to any other
property or assets of the Company or any Restricted Subsidiary of the Company;

     (5) Liens to secure the performance of statutory obligations, surety or appeal bonds,
government contracts, performance bonds or other obligations of a like nature incurred in
the ordinary course of business (such as (a) Liens of landlords, carriers, warehousemen,
mechanics and materialmen and other similar Liens imposed by law and (b) Liens in the form
of deposits or pledges incurred in connection with worker’s compensation, unemployment
compensation and other types of social security (excluding Liens arising under Employee
Retirement Income Security Act of 1974));

     (6) Liens existing on the Covenant Termination Date;

     (7) survey exceptions, easements or reservations of, or rights of others for, licenses,
rights-of-way, sewers, electric lines, telegraph and telephone lines and other similar
purposes, or zoning or other restrictions as to the use of real property that were not
incurred in connection with Indebtedness and that do not in the aggregate materially
adversely affect the value of said properties or materially impair their use in the
operation of the business of such Person;

61

 

     (8) Liens created for the benefit of (or to secure) the Notes (or any Subsidiary
Guarantees);

     (9) Liens arising from Uniform Commercial Code financing statement filings regarding
operating leases entered into by the Company and its Restricted Subsidiaries in the ordinary
course of business;

     (10) Liens securing Permitted Refinancing Indebtedness incurred to refinance
Indebtedness that was previously so secured as permitted by the indenture; provided that any
such Lien is limited to all or part of the same property or assets (plus improvements,
accessions, proceeds or dividends or distributions in respect thereof) that secured (or,
under the written arrangements under which the original Lien arose, could secure) the
Indebtedness being refinanced or is in respect of property that is the security for a
Permitted Lien hereunder;

     (11) Liens securing Hedging Obligations of the Company or any of its Restricted
Subsidiaries, which transactions or obligations are incurred for bona fide hedging purposes
(and not for speculative purposes) of the Company or its Restricted Subsidiaries (as
determined in good faith by the Board of Directors or senior management of the Company);

     (12) Liens to secure Indebtedness (including Acquired Debt, Capital Lease Obligations,
mortgage financings or purchase money obligations) incurred for the purpose of financing all
or any part of the purchase price, lease or cost of design, installation, construction or
improvement of property, plant or equipment used in the business of the Company or any
Restricted Subsidiary; provided that any such Lien (a) covers only the assets acquired,
constructed or improved with such Indebtedness and (b) is created within 270 days of such
acquisition, construction or improvement;

     (13) Liens required by any regulation, or order of or arrangement or agreement with any
regulatory body or agency, so long as such Liens do not secure Indebtedness;

     (14) Liens on assets transferred to a Securitization Subsidiary or on assets of a
Securitization Subsidiary, in either case, incurred in connection with a Qualified
Securitization Transaction; and

     (15) other Liens with respect to Indebtedness in an aggregate principal amount that
does not exceed the greater of (a) 20% of Consolidated Total Assets and (b) the amounts
available under clauses (2) and (14) of the definition of “Permitted Liens” in effect prior
to the Covenant Termination Date.

Section 4.12 Stay, Extension and Usury Laws.

     The Company covenants (to the extent that it may lawfully do so) that it shall not at any time
insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and

62

 

covenants that it shall not, by resort to any such law, hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the execution of every such
power as though no such law has been enacted.

ARTICLE 5.

SUCCESSORS

     Article 9 of the Base Indenture shall be superseded in its entirety by this Article 5 with
respect to, and solely for the benefit of the holders of, the Notes, provided that this Article 5
shall not become a part of the terms of any other series of Securities.

Section 5.01 Merger, Consolidation or Sale of Assets.

     (a) The Company may not, directly or indirectly, consolidate or merge with or into another
Person (whether or not the Company is the surviving Person) or sell, assign, transfer, convey,
lease or otherwise dispose of all or substantially all of its properties or assets in one or more
related transactions, to another Person, unless:

     (1) either:

     (A) the Company is the surviving Person or

     (B) the Person formed by or surviving any such consolidation or merger (if
other than the Company) or to which such sale, assignment, transfer, conveyance or
other disposition has been made is an entity organized or existing under the laws of
the United States of America, any state thereof or the District of Columbia;
provided that, if such entity is not a corporation, a co-obligor of the Notes is a
corporation;

     (2) the Person formed by or surviving any such consolidation or merger (if other
than the Company) or the Person to which such sale, assignment, transfer, conveyance or
other disposition has been made assumes, by supplemental indenture in a form reasonably
satisfactory to the Trustee, all the obligations of the Company under the Notes and the
Indenture;

     (3) immediately after such transaction no Default or Event of Default exists; and

     (4) the Company or the Person formed by or surviving any such consolidation or merger
(if other than the Company), or to which such sale, assignment, transfer, conveyance or
other disposition has been made will, on the date of such transaction after giving pro forma
effect thereto and any related financing transactions as if the same had occurred at the
beginning of the applicable four-quarter period, (a) be permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.02(a) hereof or (b) have a Fixed Charge Coverage Ratio that is no worse than the

Opinion of Counsel, each stating that such transaction or series of transactions and the
supplemental indenture, if any, in respect thereto comply with this Section 5.01.

     (b) The sale, assignment, transfer, lease, conveyance or other disposition of all or
substantially all of the properties or assets of one or more Subsidiaries of the Company, which
properties or assets, if held by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties or assets of the Company on a consolidated basis, shall be
deemed to be the transfer of all or substantially all of the properties or assets of the Company.

     (c) Section 5.01(a) hereof shall not apply to any sale, assignment, transfer, conveyance,
lease or other disposition of assets between or among the Company or any of its Restricted

the Company in another jurisdiction so long as the amount of Indebtedness of the Company and its
Restricted Subsidiaries is not increased thereby.

Section 5.02 Successor Corporation Substituted.

     The surviving Person shall succeed to, and be substituted for, and may exercise every right
and power of the Company under the Indenture; provided, however, that the predecessor entity shall
not be released from any obligations with respect to the payment of the Notes in the case of:

     (a) a sale, transfer, assignment, conveyance or other disposition (unless such sale, transfer,
assignment, conveyance or other disposition is of all or substantially all of the assets of the
Company, taken as a whole), or

ARTICLE 6.

DEFAULTS AND REMEDIES

Section 6.01 Events of Default.

     “Event of Default” with respect to the Notes of each series shall not have the meaning
assigned to such term by Section 5.1 of the Base Indenture. Each of the following constitutes an

Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after
the Issue Date, if that default:

     (1) is caused by a failure to pay principal of, or interest or premium, if any, on such
Indebtedness on or prior to the expiration of any grace period provided in such Indebtedness
on the date of such default (a “Payment Default”); or

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

in each case, the principal amount of any such Indebtedness, together with the principal amount of

65

 

     (3) if the default that is the basis for such Event of Default has been cured;

     (h) failure by the Company or any of its Restricted Subsidiaries to pay final non-appealable
judgments entered by a court or courts of competent jurisdiction aggregating in excess of $100.0
million, which judgments are not paid, discharged or stayed for a period of 60 days;

and such order or decree remains unstayed and in effect for 60 consecutive days.

     The Holders of at least a majority in aggregate principal amount of the Notes then outstanding
by notice to the Trustee may on behalf of the Holders of all of the Notes 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 on, or the principal of, the Notes.

66

 

     The Company shall within 5 days of becoming aware of any Default or Event of Default, deliver
to the Trustee a statement specifying such Default or Event of Default.

Section 6.02 Acceleration.

     In addition to the remedies set forth in Article 5 of the Base Indenture, the remedies of the
Trustee and the Holders set forth below shall apply with respect to the Notes.

     (a) If any Event of Default (other than those of the type described in Section 6.01(i) or (j)
hereof) occurs and is continuing, the Trustee may, and the Trustee upon the request of Holders of
25% in principal amount of the outstanding Notes shall, or the Holders of at least 25% in principal
amount of outstanding Notes may, declare the principal of all the Notes, together with all accrued
and unpaid interest, premium, if any, to be due and payable by notice in writing to the Company and
the Trustee specifying the respective Event of Default and that such notice is a notice of
acceleration, and the same shall become immediately due and payable.

     (b) In the case of an Event of Default specified in Section 6.01(i) or (j) hereof, all
outstanding Notes shall become due and payable immediately without any further action or notice on
the part of the Trustee or the Holders. Holders may not enforce the Indenture or the Notes except
as provided in the Indenture.

     (c) The Holders of a majority in aggregate principal amount of the outstanding Notes by notice
to the Trustee and the Company may rescind and annul any declaration of acceleration if the
rescission would not conflict with any judgment or decree and if all existing Events of Default
have been cured or waived except nonpayment of principal, premium or interest that has become due
solely because of the acceleration. No such rescission shall affect any subsequent Default or
impair any right consequent thereto.

Section 6.03 Limitation on Suits.

     Except to enforce the right to receive payment of principal, premium, if any, or interest, if
any, when due, no Holder of a Note may pursue any remedy with respect to the Indenture or the Notes
unless:

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

     (b) 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;

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

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

     (e) 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.

ARTICLE 7.

TRUSTEE

Section 7.01 Rights and Duties of Trustee.

     The Trustee shall have the rights and duties set forth in the Base Indenture. In addition, if
an Event of Default has occurred and is continuing, (i) the Trustee shall exercise such of the
rights and powers vested in it by the Indenture, and use the 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 and (ii) the Trustee will be under no obligation to exercise any of the rights
or powers under the Indenture at the request or direction of any Holders of Notes unless such
Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against any
loss, liability or expense.

ARTICLE 8.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     Article 10 of the Base Indenture shall be superseded in its entirety by this Article 8 and
Article 11 with respect to, and solely for the benefit of the holders of, the Notes, provided that
this Article 8 and Article 11 shall not become a part of the terms of any other series of
Securities.

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

     The Company may, at its option and at any time, elect to have either Sections 8.02 or 8.03
hereof be applied to all outstanding Notes upon compliance with the conditions set forth in this
Article 8. Any such election shall be evidenced by a Board Resolution set forth in an Officer’s
Certificate.

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 shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be deemed to have been discharged from its obligations with respect to all outstanding
Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”)
and each Guarantor, if any, shall be released from all of its obligations under its Subsidiary
Guaranty. For this purpose, Legal Defeasance means that the Company shall be deemed to have paid
and discharged the entire Debt represented by the outstanding Notes, which shall thereafter be
deemed to be “outstanding” only for the purposes of Section
8.05 hereof and the other Sections of
the Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations
under the Notes and the 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
shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as
more fully set forth in such Section, payments in respect of the principal of, premium, if any, or
interest on such Notes when such payments are due, (b) the Company’s obligations with respect to
such Notes under Article 2 of this Supplemental

68

 

Indenture and Sections 3.1 and 3.2 of the Base Indenture, (c) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and the Company’s and the Guarantor’s, if any,
obligations in connection therewith and (d) this Article 8. If the Company exercises under Section
8.01 hereof the option applicable to this Section 8.02, subject to the satisfaction of the
conditions set forth in Section 8.04 hereof, payment of the Notes may not be accelerated because of
an Event of Default. 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 shall, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, be released from its obligations under the covenants contained in Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.09 and 4.10 hereof, and the operation of Section 5.01(a)(4) hereof, with
respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are
satisfied (hereinafter, “Covenant Defeasance”) and each Guarantor, if any, shall be released from
all of its obligations under its Subsidiary Guaranty with respect to such covenants in connection
with such outstanding Notes and the Notes shall 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 shall continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes shall not be deemed
outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Notes, the Company may omit to comply with and shall 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 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 shall not constitute a Default or an Event of Default under Section 6.01 hereof,
but, except as specified above, the remainder of the Indenture and such Notes shall be unaffected
thereby. If the Company exercises under Section 8.01 hereof the option applicable to this Section
8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, payment of
the Notes may not be accelerated because of an Event of Default specified in clause (c) (with
respect to the covenant contained in Section 5.01(a)(4) hereof), clause (d) (with respect to the
covenants contained in Section 4.02, 4.03, 4.05 and 4.09 hereof), clause (f) (with respect to the
covenants contained in Sections 4.04, 4.06, 4.07 and 4.10 hereof), and clauses (g), (h), (i) and
(j) (but in the case of (i) and (j) of Section 6.01 hereof, with respect to Significant
Subsidiaries only).

Section 8.04 Conditions to Legal or Covenant Defeasance.

     The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof
to the outstanding Notes.

     The Legal Defeasance or Covenant Defeasance may be exercised only if:

     (a) the Company irrevocably deposits with the Trustee, in trust, for the benefit of the
Holders of the Notes, cash in dollars, Government Securities, or a combination of cash in dollars
and Government Securities, in amounts as will be sufficient, in the opinion of a nationally

69

 

recognized firm of independent public accountants, to pay the principal of, or interest and
premium, if any, and interest on the outstanding Notes on the Stated Maturity or on the applicable
Redemption Date, as the case may be, and the Company must specify whether the Notes are being
defeased to maturity or to such particular Redemption Date;

     (b) in the case of Legal Defeasance, the Company shall deliver to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and
exclusions, (i) the Company has received from, or there has been published by, the Internal Revenue
Service a ruling or (ii) subsequent to the Issue Date, 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, subject to customary assumptions and exclusions, 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;

     (c) in the case of Covenant Defeasance, the Company has delivered to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and
exclusions, 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;

     (d) no Default or Event of Default has occurred and is continuing on the date of such deposit
(other than a Default or Event of Default resulting from the borrowing of funds to be applied to
make such deposit and the grant of any Lien securing such borrowing);

     (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of,
or constitute a default under, any material agreement or instrument (other than the Indenture) to
which the Company or any Subsidiary is a party or by which the Company or any Subsidiary is bound
(other than resulting from the borrowing of funds to be applied to make such deposit and the grant
of any Lien securing such borrowing);

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

     (g) the Company delivers to the Trustee an Officer’s 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.

			
	Section 8.05	 	Deposited Cash and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions.

     Subject to Section 8.06 hereof, all cash and 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

70

 

outstanding Notes shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Notes and the 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 all sums due and to become due thereon in respect of principal, premium, if any, and
interest but such cash and securities need not be segregated from other funds except to the extent
required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the cash or 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.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay
to the Company from time to time upon the request of the Company any cash or Government Securities
held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm
of independent certified public accountants expressed in a written certification thereof delivered
to the Trustee (which may be the certification delivered under Section 8.04(a) 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.

     The Trustee shall promptly, and in any event, no later than five (5) Business Days, pay to the
Company after request therefor, any excess money held with respect to the Notes at such time in
excess of amounts required to pay any of the Company’s Obligations then owing with respect to the
Notes.

     Any cash or Government Securities deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal, premium, if any, or interest on any Note
and remaining unclaimed for one year after such principal, premium, 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) shall
be discharged from such trust; and the Holder shall thereafter, as an unsecured creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such cash and securities, and all liability of the Company as trustee thereof, shall
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 cause to be published once, in The New
York Times and The Wall Street Journal (national edition), notice that such cash and securities
remains unclaimed and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such cash and
securities then remaining shall be repaid to the Company.

Section 8.07 Reinstatement.

     If the Trustee or Paying Agent is unable to apply any cash or. Government Securities in
accordance with Sections 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 obligations under the Indenture and the Notes shall be

71

 

revived and reinstated as though no deposit had occurred pursuant to Sections 8.02 or 8.03
hereof until such time as the Trustee or Paying Agent is permitted to apply all such cash and
securities in accordance with Sections 8.02 or 8.03 hereof, as the case may be; provided, however,
that, if the Company makes any payment of principal of, premium, if any, or interest on any Note
following the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders to receive such payment from the cash and securities held by the Trustee or Paying
Agent.

ARTICLE 9.

AMENDMENT, SUPPLEMENT AND WAIVER

     Article 8 of the Base Indenture shall be superseded in its entirety by this Article 9 with
respect to, and solely for the benefit of the holders of, the Notes, provided that this Article 9
shall not become a part of the terms of any other series of Securities.

Section 9.01 Without Consent of Holders of Notes.

     Notwithstanding Section 9.02 of this Supplemental Indenture, the Company and the Trustee may

Holders of Notes or that does not adversely affect the legal rights under the Indenture of
any such Holder;

be incurred by the Indenture; or

     (6) to comply with requirements of the SEC in order to effect or maintain the

of the “Description of Notes” in the Company’s prospectus related to the Notes to the extent
that such provision in the “Description of Notes” was intended to be a substantially
verbatim recitation of a provision of the Indenture, the Notes or the Guarantees.

Section 9.02 With Consent of Holders of Notes.

     Except as provided below in this Section 9.02, the Company and the Trustee may amend or
supplement the Indenture and the Notes with the consent of the Holders of at least a majority in
aggregate principal amount of the Notes then outstanding voting as a single class (including,
without limitation, consents obtained in connection with a purchase of or tender offer or exchange
offer for the Notes), and, subject to Section 6.01 hereof, any existing Default or Event of Default
or compliance with any provision of the Indenture, the Notes or any Subsidiary Guarantee may be
waived with the consent of the Holders of at least a majority in aggregate principal amount of the
Notes then outstanding voting as a single class (including, without limitation, consents obtained
in connection with a purchase of or tender offer or exchange offer for the Notes).

     Without the consent of each Holder affected, an amendment or waiver 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

default that resulted from such acceleration);

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

73

Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive
payments of principal of, or interest or premium, if any, on the Notes;

     (7) waive a redemption or repurchase payment with respect to any Note (including a
payment required by the provisions described under Sections 4.05 or 4.09 hereof;

     (8) make any change in the ranking of the Notes in a manner adverse to the Holders of
the Notes; or

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

     The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Persons entitled to consent to any supplemental indenture. If a record date is
fixed, the Holders on such record date, or their duly designated proxies, and only such Persons,
shall be entitled to consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided that unless such consent shall have become effective by
virtue of the requisite percentage having been obtained prior to the date which is 120 days after
such record date, any such consent previously given shall automatically and without further action
by any Holder be cancelled and of no further effect.

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

     After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Company shall mail to the Holder of each Note affected thereby to such Holder’s address appearing
in the Note Register a notice briefly describing the amendment, supplement or waiver. Any failure
of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such amended or supplemental indenture or waiver.

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Trustee to Sign Amendments, etc.

     The Trustee shall 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 amendment or supplemental indenture
until its Board of Directors approves it. In executing any amended or supplemental indenture, the
Trustee shall be provided with and (subject to Section 7.01 hereof) shall be fully protected in
relying upon an Officer’s Certificate and an Opinion of Counsel stating that the execution of such
amended or supplemental indenture is authorized or permitted by the Indenture and that such amended
or supplemental indenture is the legal, valid and binding obligations of the Company enforceable
against it in accordance with its terms, subject to customary exceptions

74

 

and that such amended or supplemental indenture complies with the provisions hereof (including
Section 9.03 hereof).

ARTICLE 10.

SUBSIDIARY GUARANTEES

Section 10.01 Subsidiary Guarantee.

     Subject to this Article 10, each Guarantor who becomes a party to this Supplemental Indenture
hereby unconditionally guarantee to each Holder of a Note authenticated and delivered by the
Trustee and to the Trustee and its successors and assigns: (a) the due and punctual payment of the
principal of, premium, if any, and interest on the Notes, subject to any applicable grace period,
whether at Stated Maturity, by acceleration, redemption or otherwise, the due and punctual payment
of interest on the overdue principal of and premium, if any, and, to the extent permitted by law,

such other obligations, that same shall 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

so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall 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.

     Each Guarantor hereby agrees that its obligations with regard to its Subsidiary Guarantee
shall be joint and several, unconditional, irrespective of the validity or enforceability of the
Notes or the obligations of the Company under the Indenture, the absence of any action to enforce
the same, the recovery of any judgment against the Company or any other obligor with respect to the
Indenture, the Notes or the Obligations of the Company under the Indenture or the Notes, any action
to enforce the same or any other circumstances (other than complete performance) which might
otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor
further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies
accorded by applicable law to guarantors and agrees not to assert or take advantage of any such
claims, rights or remedies, including but not limited to: (a) any right to require any of the
Trustee, the Holders or the Company (each a “Benefited Party”), as a condition of payment or
performance by such Guarantor, to (1) proceed against the Company, any other guarantor (including
any other Guarantor) of the Obligations under the Subsidiary Guarantees or any other Person, (2)
proceed against or exhaust any security held from the Company, any such other guarantor or any
other Person, (3) proceed against or have resort to any balance of any deposit account or credit on
the books of any Benefited Party in favor of the Company or any other Person, or (4) pursue any
other remedy in the power of any Benefited Party whatsoever; (b) any defense arising by reason of
the incapacity, lack of authority or any disability or other defense of the Company including any
defense based on or arising out of the lack of validity or the unenforceability of the Obligations
under the Subsidiary Guarantees or any agreement or instrument relating thereto or by reason of the
cessation of the liability of the Company from any cause other than payment in full of the
Obligations under the Subsidiary Guarantees; (c) any

75

 

defense based upon any statute or rule of law which provides that the obligation of a surety
must be neither larger in amount nor in other respects more burdensome than that of the principal;
(d) any defense based upon any Benefited Party’s errors or omissions in the administration of the
Obligations under the Subsidiary Guarantees, except behavior which amounts to bad faith; (e)(1) any
principles or provisions of law, statutory or otherwise, which are or might be in conflict with the
terms of the Subsidiary Guarantees and any legal or equitable discharge of such Guarantor’s
obligations hereunder, (2) the benefit of any statute of limitations affecting such Guarantor’s
liability hereunder or the enforcement hereof, (3) any rights to set-offs, recoupments and
counterclaims and (4) promptness, diligence and any requirement that any Benefited Party protect,
secure, perfect or insure any security interest or lien or any property subject thereto; (f)
notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of
any action or inaction, including acceptance of the Subsidiary Guarantees, notices of Default under
the Notes or any agreement or instrument related thereto, notices of any renewal, extension or
modification of the Obligations under the Subsidiary Guarantees or any agreement related thereto,
and notices of any extension of credit to the Company and any right to consent to any thereof; (g)
to the extent permitted under applicable law, the benefits of any “One Action” rule and (h) any
defenses or benefits that may be derived from or afforded by law which limit the liability of or
exonerate guarantors or sureties, or which may conflict with the terms of the Subsidiary
Guarantees. Except to the extent expressly provided herein, including Sections 4.10, 8.02, 8.03
and 10.05, hereof, each Guarantor hereby covenants that its Subsidiary Guarantee shall not be
discharged except by complete performance of the obligations contained in its Subsidiary Guarantee
and the Indenture.

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

     Each Guarantor agrees that it shall 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, (x) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Section 6.02 hereof for the
purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby and (y) in the event
of any declaration of acceleration of such obligations as provided in Section 6.02 hereof, such
obligations (whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors shall 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 Subsidiary Guarantee.

Section 10.02 Limitation on Guarantor Liability.

     (a) Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is
the intention of all such parties that the guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent

76

 

Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any guarantee. To effectuate the foregoing intention, the Trustee, the
Holders and the Guarantors hereby irrevocably agree that each Guarantor’s liability shall be that
amount from time to time equal to the aggregate liability of such Guarantor under the guarantee,
but shall be limited to the lesser of (i) the aggregate amount of the Company’s obligations under
the Notes and the Indenture or (ii) the amount, if any, which would not have (1) rendered the
Guarantor “insolvent” (as such term is defined in the Federal Bankruptcy Code and in the Debtor and
Creditor Law of the State of New York) or (2) left it with unreasonably small capital at the time
its guarantee with respect to the Notes was entered into, after giving effect to the incurrence of
existing Indebtedness immediately before such time; provided, however, it shall be a presumption in
any lawsuit or proceeding in which a Guarantor is a party that the amount guaranteed pursuant to
the guarantee with respect to the Notes is the amount described in clause (i) above unless any
creditor, or representative of creditors of the Guarantor, or debtor in possession or Trustee in
bankruptcy of the Guarantor, otherwise proves in a lawsuit that the aggregate liability of the
Guarantor is limited to the amount described in clause (ii).

     (b) In making any determination as to the solvency or sufficiency of capital of a Guarantor in
accordance with the proviso of Section 10.02(a) hereof, the right of each Guarantor to contribution
from other Guarantors and any other rights such Guarantor may have, contractual or otherwise, shall
be taken into account.

Section 10.03 Execution and Delivery of Subsidiary Guarantee.

     To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Guarantor hereby
agrees that a notation of such Subsidiary Guarantee in substantially the form included in
Exhibit B attached hereto shall be endorsed by an Officer of such Guarantor on each Note
authenticated and delivered by the Trustee.

     Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 hereof
shall remain in full force and effect notwithstanding any failure to endorse on each Note a
notation of such Subsidiary Guarantee.

     The Company hereby agrees that it shall cause each Person that becomes obligated to provide a
Subsidiary Guarantee pursuant to Section 4.10 hereof to execute a supplemental indenture in the
form included in Exhibit C attached hereto, pursuant to which such Person provides the
guarantee set forth in this Article 10 and otherwise assumes the obligations and accepts the rights
of a Guarantor under the Indenture, in each case with the same effect and to the same extent as if
such Person had been named herein as a Guarantor. The Company also hereby agrees to cause each
such new Guarantor to evidence its guarantee by endorsing a notation of such Subsidiary Guarantee
on each Note as provided in this Section 10.03.

ARTICLE 11.

SATISFACTION AND DISCHARGE

     Article 10 of the Base Indenture shall be superseded in its entirety by Article 8 hereof and
this Article 11 with respect to, and solely for the benefit of the holders of, the Notes, provided

that Article 8 hereof and this Article 11 shall not become a part of the terms of any other
series of Securities.

Section 11.01 Satisfaction and Discharge.

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

     (a) either:

     (1) 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 been deposited in trust and
thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

     (2) 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, and the Company 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 dollars, U.S. Government Securities, or a combination of cash in dollars
and U.S. Government Securities, in such amounts as will be sufficient without consideration
of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes
not delivered to the Trustee for cancellation for principal, premium, if any, and accrued
interest to the date of maturity or redemption;

     (b) no Default or Event of Default (other than a Default of Event of Default resulting from
borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing)
has occurred and is continuing on the date of the deposit or will occur as a result of the deposit
and the deposit will not result in a breach or violation of, or constitute a default under, any
material agreement or instrument (other than resulting from the borrowing of funds to be applied to
make such deposit and the grant of any Liens securing such borrowing) to which the Company is a
party or by which the Company is bound;

     (c) the Company has paid or caused to be paid all sums payable by it under the Indenture; and

     (d) the Company has delivered irrevocable instructions to the Trustee to apply the deposited
money toward the payment of the Notes at maturity or the Redemption Date, as the case may be.

     In addition, the Company must deliver an Officer’s Certificate and an opinion of counsel to
the Trustee stating that all conditions precedent to satisfaction and discharge have been
satisfied.

Section 11.02 Deposited Cash and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions.

     Subject to Section 11.03 hereof, all cash and Government Securities (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 11.02, the “Trustee”) pursuant to Section 11.01 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes
and the 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, if any, and interest but such
cash and securities need not be segregated from other funds except to the extent required by law.

Section 11.03 Repayment to Company.

     Any cash or Government Securities deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any, or interest on, any
Note and remaining unclaimed for two years after such principal, and premium, 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) shall be discharged from such trust; and the Holder shall thereafter, as an unsecured
creditor, look only to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such cash and securities, and all liability of the Company as trustee
thereof, shall 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 cause to be published
once, in The New York Times and The Wall Street Journal (national edition), notice that such cash
and securities remains unclaimed and that, after a date specified therein, which shall not be less
than 30 days from the date of such notification or publication, any unclaimed balance of such cash
and securities then remaining shall be repaid to the Company.

(Back of Note)

7.50% Senior Notes due 2019

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

     1. Interest. AMERIGROUP Corporation, a Delaware corporation (the “Company”), promises to pay
interest on the principal amount of this Note at 7.50% per annum until maturity. The Company shall
pay interest semi-annually on May 15 and November 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
shall accrue from the most recent date to which interest has been paid on the Notes (or one or more
Predecessor Notes) or, if no interest has been paid, from November 16, 2011. Interest shall be
computed on the basis of a 360-day year of twelve 30-day months.

     2. Method of Payment. The Company shall pay interest on the Notes (except defaulted interest)
to the Persons in whose name this Note (or one or more Predecessor Notes) is registered at the
close of business on the May 1 or November 1 next preceding the Interest Payment Date, even if such
Notes are cancelled after such record date and on or before such Interest Payment Date, except as
provided in Section 2.14 of the Supplemental Indenture with respect to defaulted interest. The
Notes shall be payable as to principal, premium, if any, and interest at the office or agency of
the Company maintained for such purpose, or, at the option of the Company, payment of interest may
be made by check mailed to the Holders at their addresses set forth in the Note Register; provided,
however, that payment by wire transfer of immediately available funds shall be required with
respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes
the Holders of which shall have provided wire transfer instructions to the Company or the Paying
Agent. Such payment shall 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 Mellon Trust Company, N.A.,
the Trustee under the Indenture, shall 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 Restricted
Subsidiaries may act in any such capacity.

     4. Indenture. The Company issued the Notes under an Indenture dated as of November 16, 2011
(the “Base Indenture”) between the Company and the Trustee, as supplemented by a First Supplemental
Indenture dated as of November 16, 2011 (the “Supplemental Indenture” and, together with the Base
Indenture, the “Indenture”). The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15
U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to
the Indenture and such Act 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.

     5. Optional Redemption.

A-3

 

          (a) Except as set forth in clauses (b), (c) and (d) of this paragraph 5, the Notes shall not
be redeemable at the option of the Company.

          (b) At any time prior to November 15, 2014, 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, but excluding Notes held by the Company or its Subsidiaries), upon not less
than 30 nor more than 60 days’ notice, at a Redemption Price equal to 107.500% of the principal
amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the
applicable date of redemption (subject to the rights of Holders of Notes on the relevant record
date to receive interest due on the relevant interest payment date), with the net cash proceeds of
an Equity Offering by the Company; provided that:

     (1) at least 65% of the aggregate principal amount of Notes originally issued
under this Supplemental Indenture (calculated after giving effect to any issuance of
Additional Notes and excluding Notes held by the Company and its Subsidiaries)
remains outstanding immediately after the occurrence of each such redemption; and

     (2) the redemption occurs within 90 days of the date of the closing of such
Equity Offering.

          (c) At any time prior to November 15, 2015, the Company may on any one or more occasions
redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at a
Redemption Price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable
Premium as of, and accrued and unpaid interest, if any, to, but not including, the applicable date
of redemption (subject to the rights of Holders of Notes on the relevant record date to receive
interest due on the relevant interest payment date).

          (d) On or after November 15, 2015, the Company may on any one or more occasions redeem all or
a part of the Notes, at its option, 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, if any, on the Notes redeemed, to the applicable date of redemption, if redeemed
during the twelve-month period beginning on November 15 of the years indicated below, subject to
the rights of Holders on the relevant record date to receive interest due on the relevant interest
payment date:

	 	 	 	 	 
	Year	 	Percentage	 
	2015
	 	 	103.750	%
	2016
	 	 	101.875	%
	2017 and thereafter
	 	 	100.000	%

     (e) 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.
Any redemption pursuant to this Paragraph 5 shall be made pursuant to the provisions of Sections
3.01 through 3.06 of the Supplemental Indenture.

A-4

 

     6. Mandatory Redemption. The Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

     7. Repurchase at Option of Holder.

          (a) Upon the occurrence of a Change of Control, Article 3 and Section 4.09 of the Supplemental
Indenture shall apply to the extent applicable.

          (b) If the Company or any of its Restricted Subsidiaries consummates an Asset Sale, Article 3
and Section 4.05 of the Supplemental Indenture shall apply to the extent applicable.

     8. Notice of Redemption. Notice of redemption shall be mailed 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. Notes in denominations larger than $2,000 may be redeemed in part but only in
whole multiples of $1,000 in excess of $2,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof
called for redemption.

     9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in
denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. This Note shall
represent the aggregate principal amount of outstanding Notes from time to time endorsed hereon and
the aggregate principal amount of Notes represented hereby may from time to time be reduced or
increased, as appropriate, to reflect exchanges and redemptions. 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.

     10. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for
all purposes.

     11. Amendment, Supplement and Waiver. The Indenture or Notes may be amended or supplemented
as provided in the Indenture.

     12. Defaults and Remedies. The Events of Default relating to the Notes are defined in Section
6.01 of the Supplemental Indenture. If any Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in 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 described in the
Supplemental Indenture, all outstanding Notes shall become due and payable 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

A-5

 

the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payment of principal or interest) if it determines
that withholding notice is in their interest. The Holders of at least a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the
Holders of all of the Notes 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 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 within 5 days of
becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying
such Default or Event of Default.

     13. Trustee Dealings with Company. Subject to certain limitations, 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.

     14. No Recourse Against Others. No past, present or future director, officer, employee,
incorporator or stockholder of the Company or of any Guarantor, as such, shall have any liability
for any obligations of the Company or any Guarantor under the Indenture, the Notes, the Subsidiary
Guarantees, if any, 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.

     15. Authentication. This Note shall not be valid until authenticated by manual, facsimile or
electronic signature of the Trustee or an authenticating agent.

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

     17. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes
and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to
Holders. No representation is made as to the accuracy of such numbers either as printed on the
