the Global Note Legend and the Private Placement Legend and deposited with or on behalf of, and

equal to the outstanding principal amount at maturity of the Notes sold in reliance on Rule 144A.

          “Acquired Debt” means, with respect to any specified Person, Indebtedness of any other Person
existing at the time such other Person is merged with or into or became a Subsidiary of such

or controlled by or under direct or indirect common control with such specified Person. For
purposes of this definition, “control,” as used with respect to any Person, will mean the
possession, directly or indirectly, of the power to direct or cause the direction of the management
or policies of such Person, whether through the ownership of voting securities, by agreement or
otherwise; provided that beneficial ownership of 10% or more of the Voting Stock of a Person will
be deemed to be control. For purposes of this definition, the terms “controlling,” “controlled by”

          “Agent” means any Registrar or Paying Agent.

 

 

          “Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial

Restricted Subsidiaries or the sale by the Company or any Restricted Subsidiary
thereof of Equity Interests in any of its Subsidiaries (other than directors’
qualifying shares and shares issued to foreign nationals to the extent required
by applicable law).

Notwithstanding the preceding, the following items, which may constitute all or a portion of any

ARTICLE TWO

THE NOTES

Section 2.01. Form and Dating.

          (a) General. The Notes and the Trustee’s certificate of authentication shall be substantially
in the form of Exhibit A. The Notes may have notations, legends or endorsements required
by law, stock exchange rule or usage. Each Note shall be dated the date of its
authentication. The Notes shall be issued in registered form without interest coupons in
minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

28

 

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

          (b) Global Notes. Notes issued in global form shall be substantially in the form of
Exhibit A (and shall include the Global Note Legend thereon and the “Schedule of Exchanges
of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be
substantially in the form of Exhibit A (but without the Global Note Legend thereon and
without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global
Note shall represent such amount of the outstanding Notes as shall be specified therein and each
shall provide that it represents the aggregate principal amount of outstanding Notes from time to
time endorsed thereon and that the aggregate principal amount of outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in
the aggregate principal amount of outstanding Notes represented thereby shall be made by the
Trustee or, if the Custodian and the Trustee are not the same Person, by the Custodian at the
direction of the Trustee, in accordance with instructions given by the Holder thereof as required
by Section 2.07 hereof.

          (c) Regulation S Global Notes. Notes offered and sold in reliance on Regulation S shall be
issued initially in the form of the Regulation S Global Note, which shall be deposited on behalf of
the purchasers of the Notes represented thereby with the Trustee, as custodian for The Depository
Trust Company (“DTC”) in New York, New York, and registered in the name of the Depositary or the
nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or
Clearstream, duly executed by the Company and authenticated by the Trustee as hereinafter provided.
The aggregate principal amount of the Regulation S Global Notes may from time to time be increased
or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee,
as the case may be, in connection with transfers of interest as hereinafter provided.

          (d) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating
Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the
“General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall
be applicable to transfers of beneficial interests in the Regulation S Global Notes that are held
by Participants through Euroclear or Clearstream.

Section 2.02. Execution and Authentication.

          At least one Officer of the Company shall sign the Notes for the Company by manual or
facsimile signature.

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

29

 

          A Note shall not be valid until authenticated by the manual signature of the Trustee. Such
signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

          The aggregate principal amount of Notes that may be authenticated and delivered under this
Indenture is unlimited.

          The Company may, subject to Article Four of this Indenture and applicable law, issue
Additional Notes under this Indenture, including Exchange Notes. The Notes issued on the Issue
Date and any Additional Notes subsequently issued shall be treated as a single class for all
purposes under this Indenture.

          At any time and from time to time after the execution of this Indenture, the Trustee shall,
upon receipt of a written order of the Company signed by an Officer of the Company (an
“Authentication Order”), authenticate Notes for original issue in an aggregate principal amount
specified in such Authentication Order. The Authentication Order shall specify the amount of Notes
to be authenticated and the date on which the Notes are to be authenticated.

          The Trustee may appoint an authenticating agent acceptable to the Company, which acceptance
shall not be unreasonably withheld, to authenticate Notes. An authenticating agent may
authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An authenticating agent has
the same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 2.03. Methods of Receiving Payments on the Notes.

          If a Holder has given wire transfer instructions to the Company, the Company shall pay all
principal, interest and premium and Liquidated Damages, if any, on that Holder’s Notes in
accordance with those instructions. All other payments on Notes shall be made at the office or
agency of the Paying Agent and Registrar within the City and State of New York unless the Company
elects to make interest payments by check mailed to the Holders at their addresses set forth in the
register of Holders.

Section 2.04. Registrar and Paying Agent.

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

30

 

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

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

Section 2.05. 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 shall hold in trust for the benefit of Holders or the Trustee all money held by
the Paying Agent for the payment of principal, premium or Liquidated Damages, if any, or interest
on the Notes, and shall notify the Trustee of any default by the Company in making any such
payment. While any such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Company or one of its Subsidiaries) shall have no further liability for the money. If the Company
or one of its Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or
reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the
Notes.

Section 2.06. Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of all Holders and shall otherwise comply with TIA
Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at
least seven Business Days before each interest payment date and at such other times as the Trustee
may request in writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of the Holders of Notes and the Company shall otherwise comply
with TIA Section 312(a).

Section 2.07. Transfer and Exchange.

          (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole
except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, or by the Depositary
or any such nominee to a successor Depositary or a nominee of such successor Depositary. All
Global Notes shall be exchanged by the Company for Definitive Notes if (i) the Depositary notifies
the Company that it (A) is unwilling or unable to continue to act as Depositary for the Global
Notes or (B) has ceased to be a clearing agency registered under the Exchange Act and, in either
case, the Company fails to appoint a successor Depositary within 120 days after receiving such
notice; (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of Definitive Notes in exchange for Global Notes (in whole but not in part); provided
that in no event shall the Regulation S Global Note be exchanged by the Company for Definitive
Notes other than in accordance with Section 2.07(c)(ii); or (iii) there shall have occurred and be
continuing a Default or Event of Default with respect to the Notes. Upon the occurrence of any of
the preceding events in (i), (ii) or (iii) above, Definitive Notes shall be

31

 

issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in
whole or in part, as provided in Sections 2.08 and 2.11 hereof. Every Note authenticated and
delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this
Section 2.07 or Section 2.08 or 2.11 hereof, shall be authenticated and delivered in the form of,
and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as

interests in the Global Notes also shall require compliance with either subparagraph (i) or (ii)
below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

     (i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in
any Restricted Global Note may be transferred to Persons who take delivery thereof in the
form of a beneficial interest in the same Restricted Global Note in accordance with the

prior to the expiration of the Restricted Period, transfers of beneficial interests in the
Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a
U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted
Global Note may be transferred to Persons who take delivery thereof in the form of a
beneficial interest in an Unrestricted Global Note. No written orders or instructions shall
be required to be delivered to the Registrar to effect the transfers described in this
Section 2.07(b)(i).

     (ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In

regarding the Person in whose name such Definitive Note shall be registered to effect the
transfer or exchange referred to in (1) above; provided that in no event shall Definitive
Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S
Global Note other than in accordance with Section 2.07(c)(ii). Upon consummation of an
Exchange Offer by the Company in accordance with Section 2.07(f),

32

 

the requirements of this
Section 2.07(b)(ii) shall be deemed to have been satisfied upon receipt by the Registrar of
the instructions contained in the Letter of Transmittal delivered by the holder of such

amount of beneficial interests transferred pursuant to subparagraph (B) or (D) above.

A holder of a beneficial interest in a Restricted Global Note may exchange such beneficial

35

 

interest for an Unrestricted Definitive Note or may transfer such beneficial interest to a
Person who takes delivery thereof in the form of an Unrestricted Definitive Note only if:

has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be

time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or
transferred to a Person who shall take delivery thereof in the form of a beneficial interest in
another Global Note or for Definitive Notes, the principal amount of Notes represented by such
Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by
the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if
the beneficial interest is being exchanged for or transferred to a Person who shall take delivery
thereof in the form of a beneficial interest in another Global Note, such other Global Note shall
be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by
the Depositary at the direction of the Trustee to reflect such increase.

     (i) General Provisions Relating to Transfers and Exchanges.

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

     (ii) No service charge shall be made to a Holder of a beneficial interest in a Global
Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but
the Company may require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than any such transfer taxes or
similar governmental charge payable upon exchange or transfer pursuant to Sections 2.11,
3.06, 3.08, 4.10, 4.13 and 9.05).

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

     (iv)
All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of
Global Notes or Definitive Notes shall be the valid and legally
binding obligations of the Company, evidencing the same debt, and entitled to the same

43

 

benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such
registration of transfer or exchange.

          (v) Neither the Registrar nor the Company shall be required (A) to issue, to register
the transfer of or to exchange any Notes during a period beginning at the opening of
business 15 days before the day of any selection of Notes for redemption under Section 3.02
and ending at the close of business on the day of selection, (B) to register the transfer of
or to exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part, (C) to register the transfer of or to
exchange a Note between a record date and the next succeeding interest payment date or (D)

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

transfer or exchange may be submitted by facsimile and may be transmitted electronically.

Section 2.08. Replacement Notes.

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

in a Global Note effected by the Trustee in accordance with the provisions hereof, and those
described in this Section as not outstanding. Except as set forth in Section 2.10, a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds the

44

 

Note; however,
Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for
purposes of Section 3.07(b).

          (b) If a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser
or protected purchaser.

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

          (d) If the Paying Agent (other than the Company, a Subsidiary of the Company or an Affiliate
of any of the foregoing) holds, on a redemption date or maturity date, money 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 2.10. 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 any Guarantor, or by any Person
directly or indirectly controlling or controlled by or under direct or indirect common control with
the Company or any Guarantor, shall be considered as though not outstanding, except that for the
purposes 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 actually knows are so owned
shall be so disregarded.

Section 2.11. Temporary Notes.

          (a) Until certificates representing Notes are ready for delivery, the Company may prepare and
the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes.

and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

          (b) Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

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
canceled Notes in accordance with its procedures for the disposition of canceled securities in
effect as of the date of such disposition (subject to the record retention requirement of the
Exchange Act). Certification of the disposition of all canceled Notes shall be delivered to the
Company. The Company may not issue new Notes to replace Notes that it has paid or that have been
delivered to the Trustee for cancellation.

45

 

Section 2.13. Defaulted Interest.

          If the Company defaults in a payment of interest on the Notes, 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 and in Section 4.01. The Company shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date of the proposed
payment. The Company 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.

Section 2.14. CUSIP Numbers.

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

Notes called for redemption also apply to portions of Notes called for redemption.

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

          (vii) the paragraph of the Notes and/or Section of this Indenture pursuant to which the
Notes called for redemption are being redeemed;

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

          (ix) any conditions that must be satisfied prior to the Company becoming obligated to
consummate such redemption.

47

 

          (b) At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at the Company’s expense; provided, however, that the Company shall have delivered to the
Trustee, at least 45 days prior to the redemption date (or such shorter period of time as may be
acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice
and setting forth the information to be stated in such notice as provided in the preceding
paragraph.

Section 3.04. Effect of Notice of Redemption.

          Except as provided below, once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the redemption date at
the redemption price. Interest, if any, on Notes called for redemption ceases to accrue on and
after the redemption date, unless the Company defaults in making the applicable redemption payment.
Notwithstanding the foregoing, a notice of redemption may be conditional and the Company’s
obligation to redeem Notes may be subject to one or more conditions that the Company, in its sole
discretion, includes in such notice.

Section 3.05. Deposit of Redemption Price.

          (a) Prior to 12:00 p.m. (noon) Eastern Time on the redemption date, the Company shall deposit
with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and
accrued and unpaid interest and Liquidated Damages, if any, on all Notes to be redeemed on that
date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited
with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued and unpaid interest and Liquidated Damages, if any, on all Notes
to be redeemed.

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

Section 3.06. Notes Redeemed in Part.

          Upon cancellation of a Note that is redeemed in part, the Company shall issue and 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. Optional Redemption.

          (a) Except as set forth in clauses (b) and (c) of this Section 3.07, the Company shall not
have the option to redeem the Notes pursuant to this Section 3.07 prior to January 15,

48

 

2010. On or after January 15, 2010, the Company may redeem all or a portion of the Notes upon not less than 30
days’ nor more than 60 days’ notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest and Liquidated Damages, if any,
to the applicable redemption date, if redeemed during the twelve-month period beginning on January
15 of the years indicated below, subject to the rights of Holders on the relevant record date to
receive interest on the relevant interest payment date:

	 	 	 
	Year	 	Percentage
	 
	 	 
	2010
	 	104.500%
	 
	 	 
	2011
	 	102.250%
	 
	 	 
	2012 and thereafter
	 	100.000%

          (b) At any time prior to January 15, 2009, the Company may, on one or more occasions, redeem
up to 35% of the aggregate principal amount of Notes issued under this Indenture (including any
Additional Notes) at a redemption price of 109.000% of the principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, to the redemption date, with the net cash
proceeds of one or more Equity Offerings; provided that (1) at least 65% of the aggregate principal
amount of Notes issued under this Indenture on the Issue Date remains outstanding immediately after
the occurrence of such redemption (excluding Notes held by the Company or its Affiliates); and (2)
the redemption must occur within 180 days of the date of the closing of such Equity Offering.

          (c) At any time prior to January 15, 2010, the Company may redeem the Notes in whole or in
part, at the Make-Whole Price, plus accrued and unpaid interest and Liquidated Damages, if any, to
the redemption date. “Make-Whole Price” with respect to a Note means the greater of:

          (1) the sum of the outstanding principal amount and Make-Whole Amount of such Note; and

          (2) the redemption price of such Note on January 15, 2010, determined pursuant to this
Indenture (104.500% of the principal amount).

          “Make-Whole Amount” with respect to a Note means an amount equal to the excess, if any, of:

          (1) the present value of the remaining interest, premium, if any, and principal
payments due on such Note as if such Note were redeemed on January 15, 2010 computed using a
discount rate equal to the Treasury Rate plus 50 basis points, over

          (2) the outstanding principal amount of such Note.

          “Treasury Rate” means the yield to maturity at the time of the computation of United States
Treasury securities with a constant maturity (as compiled by and published in the most recent
Federal Reserve Statistical Release H.15(519), which has become publicly available

49

 

at least two business days prior to the date of the redemption notice or, if such Statistical Release is no
longer published, any publicly available source of similar market date) most nearly equal to the
then remaining maturity of the Notes assuming redemption of the Notes on January 15, 2010;
provided, however, that if the Make-Whole Average Life of such Notes is not equal to the constant
maturity of the United States Treasury security for which a weekly average yield is given, the
Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for
which such yields are given, except that if the Make-Whole Average Life of such Notes is less than
one year, the weekly average yield on actually traded United States Treasury securities adjusted to
a constant maturity of one year shall be used. “Make-Whole Average Life” means the number of years
(calculated to the nearest one-twelfth) between the date of redemption and January 15, 2010.

          (d) Any redemption pursuant to this Section 3.07 shall be made in accordance with the
provisions of Sections 3.01 through 3.06.

Section 3.08. Repurchase Offers.

          In the event that, pursuant to Section 4.10 or Section 4.13, the Company shall be required to
commence an offer to all Holders to purchase all or a portion of their respective Notes (a
“Repurchase Offer”), it shall follow the procedures specified in such Sections and, to the extent
not inconsistent therewith, the procedures specified below.

          The Repurchase Offer shall remain open for a period of no less than 30 days and no more than
60 days following its commencement, except to the extent that a longer period is required by
applicable law (the “Offer Period”). No later than three Business Days after the termination of
the Offer Period (the “Purchase Date”), the Company shall purchase the principal amount of Notes
required to be purchased pursuant to Section 4.10 or 4.13 hereof (the “Offer Amount”) or, if less
than the Offer Amount has been tendered, all Notes tendered in response to the Repurchase Offer.
Payment for any Notes so purchased shall be made in the same manner as interest payments are made.

          If the Purchase Date is on or after an interest 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 record date, and no additional interest shall
be payable to Holders who tender Notes pursuant to the Repurchase Offer.

          Upon the commencement of a Repurchase Offer, the Company shall send, by first class mail, a
notice to the Trustee and each of the Holders. The notice shall contain all instructions and
materials necessary to enable such Holders to tender Notes pursuant to the Repurchase Offer. The
Repurchase Offer shall be made to all Holders. The notice, which shall govern the terms of the
Repurchase Offer, shall state:

          (i) that the Repurchase Offer is being made pursuant to this Section 3.08 and Section
4.10 or Section 4.13 hereof, and the length of time the Repurchase Offer shall remain open;

          (ii) the Offer Amount, the purchase price and the Purchase Date;

50

 

           (iii) that any Note not tendered or accepted for payment shall continue to accrue
interest and Liquidated Damages, if any;

          (iv) that, unless the Company defaults in making such payment, any Note (or portion
thereof) accepted for payment pursuant to the Repurchase Offer shall cease to accrue
interest and Liquidated Damages, if any, after the Purchase Date;

          (v) that Holders electing to have a Note purchased pursuant to a Repurchase Offer may
elect to have Notes purchased equal to $2,000 and integral multiples of $1,000 in excess
thereof only;

          (vi) that Holders electing to have a Note purchased pursuant to any Repurchase Offer
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 at least three days before the Purchase Date;

          (vii) 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, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of the Note the Holder delivered for purchase and a
statement that such Holder is withdrawing his election to have such Note purchased;

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

          (ix) that Holders whose Notes were purchased only in part shall be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered (or
transferred by book-entry transfer).

          On the Purchase Date, the Company shall, to the extent lawful, accept for payment on a pro
rata basis to the extent necessary, the Offer Amount of Notes (or portions thereof) tendered
pursuant to the Repurchase Offer, or if less than the Offer Amount has been tendered, all Notes
tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes (or
portions thereof) were accepted for payment by the Company in accordance with the terms of this
Section 3.08. The Company, the Depositary or the Paying Agent, as the case may be, shall promptly
(but in any case not later than three days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of Notes tendered by such Holder, as the
case may be, and accepted by the Company for purchase, and the Company shall promptly issue a new
Note. The Trustee, upon written request from the Company shall authenticate and mail or deliver
such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly

51

 

mailed or delivered by the Company to the
respective Holder thereof. The Company shall publicly announce the results of the Repurchase Offer
on the Purchase Date.

          (c) In determining whether any Restricted Payment is permitted by this Section 4.07, the
Company may allocate or reallocate all or any portion of such Restricted Payment among the clauses
of the preceding paragraph (b) or among such clauses and the provisions of paragraph (a) of this
Section 4.07, provided that at the time of such allocation or reallocation, all such Restricted
Payments, or allocated portions thereof, would be permitted under the various provisions of this
Section 4.07.

          (d) The amount of all Restricted Payments shall be the Fair Market Value on the date of the
Restricted Payment of the asset(s) 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. The
Fair Market Value of any assets or securities (other than cash or Cash Equivalents) that are
required to be valued by this Section 4.07 will be determined by the Board of Directors of the
Company whose resolution with respect thereto will be delivered to the Trustee. The Board of
Directors’ determination must be based upon an opinion or appraisal issued by an Independent
Financial Advisor if such Fair Market Value exceeds $15.0 million.

Section 4.08. Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to create
or permit to exist or become effective any consensual encumbrance or restriction on the ability of
any Restricted Subsidiary to:

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

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

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

58

 

          (b) However, the preceding restrictions in Section 4.08(a) shall not apply to encumbrances or
restrictions:

     (i) existing under, by reason of or with respect to any Credit Facility, Existing
Indebtedness, Capital Stock or any other agreements or instruments in effect on the Issue
Date and any amendments, modifications, restatements, renewals, extensions, supplements,
refundings, replacements or refinancings thereof, provided that the encumbrances and
restrictions in any such amendments, modifications, restatements, renewals, increases,
extensions, supplements, refundings, replacement or refinancings are, in the reasonable good
faith judgment of the Chief Executive Officer and the Chief Financial Officer of the
Company, no more restrictive, taken as a whole, than those contained in the Credit
Agreement, Existing Indebtedness, Capital Stock or such other agreements or instruments, as
the case may be, as in effect on the Issue Date;

     (ii) set forth in this Indenture, the Notes and the Subsidiary Guarantees or contained
in any other instrument relating to any other Indebtedness so long as the Board of Directors
of the Company determines that such encumbrances or restrictions are no more restrictive in
the aggregate than those contained in this Indenture;

     (iii) existing under, by reason of or with respect to applicable law, rule, regulation
or order;

     (iv) with respect to any Person or the property or assets of a Person acquired by the
Company or any of its Restricted Subsidiaries existing at the time of such acquisition,
which encumbrance or restriction is not applicable to any Person or the properties or assets
of any Person, other than the Person, or the property or assets of the Person, so acquired
and any amendments, modifications, restatements, renewals, increases, extensions,
supplements, refundings, replacements or refinancings thereof, provided that the
encumbrances and restrictions in any such amendments, modifications, restatements, renewals,
increases, extensions, supplements, refundings, replacement or refinancings are, in the
reasonable good faith judgment of the Chief Executive Officer and the Chief Financial
Officer of the Company, no more restrictive, taken as a whole, than those in effect on the
date of the acquisition;

     (v) Indebtedness Incurred or Capital Stock issued by any Restricted Subsidiary,
provided that the restrictions contained in the agreements or instruments governing such
Indebtedness or Capital Stock (a) either (i) apply only in the event of a
payment default or a default with respect to a financial covenant in such agreement or
instrument or (ii) shall not materially affect the Company’s ability to pay all principal,
interest and premium and Liquidated Damages, if any, on the Notes, as determined in good
faith by the Chief Executive Officer and the Chief Financial Officer of the Company, whose
determination shall be conclusive; and (b) are not materially more disadvantageous to the
Holders of the Notes than is customary in comparable financings (as determined by the Chief
Financial Officer of the Company, whose determination shall be conclusive);

59

 

     (vi) in the case of clause (iii) of Section 4.08(a):

     (1) that restrict in a customary manner the subletting, assignment or transfer
of any property or asset that is a lease, license, conveyance or contract or similar
property or asset;

     (2) existing by virtue of any transfer of, agreement to transfer, option or
right with respect to, or Lien on, any property or assets of the Company or any
Restricted Subsidiary thereof not otherwise prohibited by this Indenture;

     (3) purchase money obligations for property acquired in the ordinary course of
business and Capital Lease Obligations;

in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock
sale agreements and other similar agreements entered into with the approval of the
Company’s Board of Directors or in the ordinary course of business, which limitation
is applicable only to the assets that are the subject of such agreements;

     (5) any instrument governing secured Indebtedness; and

     (6) arising or agreed to in the ordinary course of business, not relating to
any Indebtedness, and that do not, individually or in the aggregate, detract from
the value of property or assets of the Company or any Restricted Subsidiary thereof
in any manner material to the Company or any Restricted Subsidiary thereof;

1

     (vii) existing under, by reason of or with respect to any agreement for the sale or
other disposition of all or substantially all of the Capital Stock of, or property and
assets of, a Restricted Subsidiary that restrict distributions by that Restricted Subsidiary
pending such sale or other disposition;

     (viii) Permitted Refinancing Indebtedness; provided 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;

     (ix) Liens permitted to be incurred under the provisions of Section 4.12 that limit the
right of the debtor to dispose of the assets subject to such Liens;

     (x) encumbrances or restrictions contained in agreements entered into in connection
with Hedging Obligations permitted from time to time under this Indenture; and

Section 4.09. Incurrence of Indebtedness.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
directly or indirectly, Incur any Indebtedness (including Acquired Debt); provided, however, that
the Company or any Guarantor may Incur Indebtedness (including Acquired Debt), 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 would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been Incurred at the beginning of such four-quarter period.

          (b) Section 4.09(a) will not prohibit the Incurrence of any of the following items of
Indebtedness (collectively, “Permitted Debt”):

     (i) the Incurrence by the Company or any Guarantor of additional Indebtedness under
Credit Facilities (including, without limitation, the Incurrence by the Company and the
Guarantors of Guarantees thereof) in an aggregate amount at any one time outstanding
pursuant to this clause (i) not to exceed a maximum amount equal to the greater of (A) $25.0
million or (B) 10.0% of the Consolidated Tangible Assets of the Company; provided, however,
that the maximum amount permitted to be outstanding under this clause (i) shall not be
deemed to limit additional Indebtedness under the Credit Facilities to the extent the
Incurrence of such additional Indebtedness is permitted pursuant to any of the other
provisions of this Section 4.09;

     (ii) the Incurrence of Existing Indebtedness;

     (iii) the Incurrence by the Company and the Guarantors of Indebtedness represented by
the Notes and the related Subsidiary Guarantees to be issued on the Issue Date and the
Exchange Notes and the related Subsidiary Guarantees to be issued pursuant to the
Registration Rights Agreement;

     (iv) the Incurrence by the Company or any Restricted Subsidiary of the Company of
Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money
obligations, in each case, Incurred for the purpose of financing all or any part of the
purchase price or cost of construction, installation, improvement,
deployment, refurbishment, modification or lease of property, plant or equipment or
furniture, fixtures and equipment, in each case used in the business of the Company or such
Restricted Subsidiary, in an aggregate amount, including all Permitted Refinancing
Indebtedness Incurred to refund, refinance or replace any Indebtedness Incurred pursuant to
this clause (iv), not to exceed the greater of (a) $10.0 million at any time outstanding or
(b) 5.0% of Consolidated Tangible Assets of the Company;

     (v) the Incurrence by the Company or any Restricted Subsidiary of the Company of
Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to
refund, refinance, replace, defease or discharge Indebtedness (other than intercompany
Indebtedness) that was permitted by this Indenture to be Incurred under Section 4.09(a) or
clauses (ii), (iii), (iv), (v), (ix) or (xiii) of this Section 4.09(b);

61

 

     (vi) the Incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness owing to and held by the Company or any of its Restricted
Subsidiaries; provided, however, that (1) 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 thereof and (2) any sale or other transfer of any such
Indebtedness to a Person that is not either the Company or a Restricted Subsidiary thereof,
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 (vi);

     (vii) the Guarantee by the Company or any of the Guarantors of Indebtedness of the
Company or a Restricted Subsidiary of the Company that was permitted to be Incurred by
another provision of this Section 4.09;

     (viii) the Incurrence by the Company or any of its Restricted Subsidiaries of Hedging
Obligations that are Incurred for the purpose of fixing, hedging or swapping interest rate,
commodity price or foreign currency exchange rate risk (or to reverse or amend any such
agreements previously made for such purposes), and not for speculative purposes, and that do
not increase the Indebtedness of the obligor outstanding at any time other than as a result
of fluctuations in interest rates, commodity prices or foreign currency exchange rates or by
reason of fees, indemnities and compensation payable thereunder;

     (ix) the Incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness in respect of workers’ compensation claims, self-insurance obligations,
bankers’ acceptances, performance bonds, completion bonds, bid bonds, appeal bonds and
surety bonds or other similar bonds or obligations, and any Guarantees or letters of credit
functioning as or supporting any of the foregoing;

     (x) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
constituting reimbursement obligations with respect to letters of credit issued in the
ordinary course of business; provided that, upon the drawing of such letters of credit or
the Incurrence of such Indebtedness, such obligations are reimbursed within one year
following such drawing or Incurrence;

     (xi) the Incurrence by the Company of Indebtedness to the extent that the net proceeds
thereof are promptly deposited to defease or to satisfy and discharge the Notes;

     (xii) the Incurrence by Foreign Subsidiaries of Indebtedness in an aggregate amount
outstanding at any one time not to exceed 15% of such Foreign Subsidiaries’ Consolidated
Tangible Assets; or

     (xiii) the Incurrence by the Company or any of its Restricted Subsidiaries of
additional Indebtedness in an aggregate amount at any time outstanding, including all
Permitted Refinancing Indebtedness Incurred to refund, refinance, defease, discharge or
replace any Indebtedness Incurred pursuant to this clause (xiii), not to exceed $10.0
million.

62

 

          (c) For purposes of determining compliance with this Section 4.09, in the event that any
proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt
described in clauses (i) through (xiii) of Section 4.09(b) above, or is entitled to be Incurred
pursuant to Section 4.09(a), the Company shall be permitted to divide and classify such item of
Indebtedness at the time of its Incurrence in any manner that complies with this Section 4.09. In
addition, any Indebtedness originally divided or classified as Incurred pursuant to clauses (i)
through (xiii) of Section 4.09(b) above may later be re-divided or reclassified by the Company such
that it will be deemed as having been Incurred pursuant to another of such clauses provided that
such re-divided or reclassified Indebtedness could be Incurred pursuant to such new clause at the
time of such re-division or reclassification. Notwithstanding the foregoing, Indebtedness under
the Credit Agreement outstanding on the Issue Date shall be deemed to have been Incurred on such
date in reliance on the exception provided by clause (i) of Section 4.09(b).

          (d) Notwithstanding any other provision of this Section 4.09, the maximum amount of
Indebtedness that may be Incurred pursuant to this Section 4.09 shall not be deemed to be exceeded
with respect to any outstanding Indebtedness due solely to the result of fluctuations in the
exchange rates of currencies.

          (e) The Company shall not Incur any Indebtedness that is subordinate in right of payment to
any other Indebtedness of the Company unless it is subordinate in right of payment to the Notes to
the same extent. The Company shall not permit any Guarantor to Incur any Indebtedness that is
subordinate in right of payment to any other Indebtedness of such Guarantor unless it is
subordinate in right of payment to such Guarantor’s Subsidiary Guarantee to the same extent. For
purposes of the foregoing, solely for the avoidance of doubt and without any other implication, no
Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the
Company or any Guarantor, as applicable, solely by reason of any Liens or Guarantees arising or
created in respect thereof or by virtue of the fact that the holders of any secured Indebtedness
have entered into intercreditor agreements giving one or more of such holders priority over the
other holders in the collateral held by them.

Section 4.10. Asset Sales.

          (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless:

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

     (ii) either (x) at least 75% of the consideration therefor received by the Company or
such Restricted Subsidiary is in the form of cash, Cash Equivalents or Replacement Assets or
a combination of the foregoing or (y) the Fair Market Value of the aggregate of all
consideration other than cash, Cash Equivalents or Replacement Assets for all Asset Sales
since the Issue Date would not exceed 10% of Consolidated Tangible Assets of the Company
after giving effect to such Asset Sales. For purposes of this Section 4.10(a)(ii), each of
the following shall be deemed to be cash:

63

 

     (A) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s
most recent consolidated balance sheet (or as would be shown on the Company’s
consolidated balance sheet as of the date of such Asset Sale) of the Company or any
Restricted Subsidiary (other than contingent liabilities, Indebtedness that is by
its terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by
the transferee of any such assets or Equity Interests pursuant to (1) a written
novation agreement that releases the Company or such Restricted Subsidiary from
further liability therefor or (2) an assignment agreement that includes, in lieu of
such a release, the agreement of the transferee or its parent company to indemnify
and hold harmless the Company or such Restricted Subsidiary from and against any
loss, liability or cost in respect of such assumed liability;

     (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 within 270 days after such Asset Sale, to the
extent of the cash received in that conversion; and

     (C) accounts receivables of a business retained by the Company or any of its
Restricted Subsidiaries following the sale of such business; provided that (i) such
accounts receivables are not more than 60 days past due and (ii) do not have a
payment date greater than 90 days from the date of the invoice creating such
accounts receivable.

     (iii) Any Asset Sale pursuant to a condemnation, appropriation or other similar taking,
including by deed in lieu of condemnation, or pursuant to the foreclosure or other
enforcement of a Permitted Lien or exercise by the related lienholder of rights with respect
thereto, including by deed or assignment in lieu of foreclosure shall not be required to
satisfy the conditions set forth in clauses (i) and (ii) of this Section 4.10(a).

     (iv) Notwithstanding the foregoing, the 75% limitation referred to in Section
4.10(a)(ii) shall be deemed satisfied with respect to any Asset Sale in which the cash or
Cash Equivalents portion of the consideration received therefrom, determined in
accordance with the foregoing provision on an after-tax basis, is equal to or greater than
what the after-tax proceeds would have been had such Asset Sale complied with the
aforementioned 75% limitation.

          (b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company or
its Restricted Subsidiaries may apply an amount equal to such Net Proceeds at its option:

     (i) to repay Indebtedness for borrowed money (other than Subordinated Indebtedness); or

     (ii) to make any capital expenditure or to purchase Replacement Assets (or enter into a
binding agreement to make such capital expenditure or to purchase such Replacement Assets;
provided that (A) such capital expenditure or purchase is

64

 

consummated within the later of
(x) 360 days after the receipt of the Net Proceeds from the related Asset Sale and (y) 180
days after the date of such binding agreement and (B) if such capital expenditure or
purchase is not consummated within the period set forth in subclause (A), the amount not so
applied will be deemed to be Excess Proceeds (as defined in Section 4.10(c))).

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

          (c) An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as
provided in Section 4.10(b) shall constitute “Excess Proceeds.” If on any date, the aggregate
amount of Excess Proceeds exceeds $10.0 million, then within 10 Business Days after such date, the
Company shall make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of
other Indebtedness that is pari passu with the Notes containing provisions similar to those set
forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of
assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be
equal to 100% of principal amount plus accrued and unpaid interest and Liquidated Damages, if any,
to the date of purchase, and will be payable in cash. If any Excess Proceeds remain unapplied after
consummation of an Asset Sale Offer, the Company and its Restricted Subsidiaries may use those
Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu
Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero.

          (d) Notwithstanding the foregoing, the sale, conveyance or other disposition of all or
substantially all of the assets of the Company and its Restricted Subsidiaries, taken as a whole,
will be governed by Sections 4.13 and 5.01 and not by this Section 4.10.

          (e) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and
any other securities laws and regulations thereunder to the extent such 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 Sales
provisions of this Indenture, or compliance with the Asset Sale provisions of this Indenture would
constitute a violation of any such laws or regulations, the Company shall comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations
under the Asset Sale provisions of this Indenture by virtue of such compliance.

Section 4.11. Transactions with Affiliates.

          (a) The Company shall not, and shall 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, make, amend, renew or extend

65

 

any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the
benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”), unless:

     (i) such Affiliate Transaction is on terms that are no less favorable to the Company or
the relevant Restricted Subsidiary than those that would have been obtained in a comparable
arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is
not an Affiliate of the Company; and

     (ii) the Company delivers to the Trustee:

     (1) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $5.0 million, a Board
Resolution set forth in an Officers’ Certificate certifying that such Affiliate
Transaction or series of related Affiliate Transactions complies with this Section
4.11 and that such Affiliate Transaction or series of related Affiliate Transactions
has been approved by a majority of the disinterested members of the Board of
Directors of the Company; and

     (2) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $15.0 million, an
opinion as to the fairness to the Company or such Restricted Subsidiary of such
Affiliate Transaction or series of related Affiliate Transactions from a financial
point of view issued by an Independent Financial Advisor.

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

     (i) transactions between or among the Company and/or its Restricted Subsidiaries;

     (ii) payment of reasonable and customary fees to, and reasonable and customary
indemnification and similar payments on behalf of, directors of the Company and its
Subsidiaries;

     (iii) any Permitted Investments or Restricted Payments that are permitted by the
provisions of Section 4.07;

     (iv) any issuance of Equity Interests (other than Disqualified Stock) of the Company,
or receipt of any capital contribution from any Affiliate of the Company;

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

     (vi) transactions pursuant to agreements or arrangements in effect on the Issue Date
and described in the Offering Memorandum, or any amendment, modification, or supplement
thereto or replacement thereof, as long as such agreement or arrangement, as so amended,
modified, supplemented or replaced, taken as a whole, is not more

66

 

disadvantageous to the
Company and its Restricted Subsidiaries than the original agreement or arrangement in
existence on the Issue Date;

     (vii) loans or advances to employees in the ordinary course of business not to exceed
$2.0 million in the aggregate at any one time outstanding; and

     (viii) any employment, consulting, service or termination agreement, employee benefit
plan or arrangement, reasonable and customary indemnification arrangements or any similar
agreement, plan or arrangement, entered into by the Company or any of its Restricted
Subsidiaries with officers, directors, consultants or employees of the Company or any of its
Subsidiaries and the payment of compensation to officers, directors, consultants and
employees of the Company or any of its Subsidiaries (including amounts paid pursuant to
employee benefit plans, employee stock option or similar plans), and any payments,
indemnities or other transactions permitted or required by bylaw, statutory provisions or
any of the foregoing agreements, plans or arrangements; so long as such agreement or payment
has been approved by a majority of the disinterested members of the Board of Directors of
the Company.

Section 4.12. Liens.

          The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create,
incur, assume or suffer to exist any Lien securing Indebtedness, upon any asset, now owned or
hereafter acquired, except Permitted Liens, unless the Notes are equally and ratably secured
(except that Liens securing Subordinated Indebtedness shall be expressly subordinate to any Lien
securing the Notes to at least the same extent such Subordinated Indebtedness is subordinate to the
Notes).

Section 4.13. Offer to Repurchase upon a Change of Control.

          (a) If a Change of Control occurs, each Holder of Notes shall have the right to require the
Company to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess
thereof) of that Holder’s Notes pursuant to an offer (a “Change of Control Offer”) on the terms set
forth in this Indenture. In the Change of Control Offer, the Company will offer payment (a “Change
of Control Payment”) in cash equal to not less than 101% of the aggregate principal amount of Notes
repurchased plus accrued and unpaid interest and Liquidated Damages, if any, to the date of
repurchase (the “Change of Control Payment Date,” which date shall be no earlier than the date of
such Change of Control). No later than 30 days following any Change of Control, the Company shall
mail a notice to each Holder describing the transaction or transactions that constitute the Change
of Control and offering to repurchase Notes on the Change of Control Payment Date specified in such
notice, which date shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed, pursuant to the procedures described in Section 3.08 (including the notice
required thereby). The Company shall comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Notes as a result of a Change
of Control. To the extent that the provisions of any securities laws or regulations conflict with
the Change of Control provisions of this

67

 

Indenture, or compliance with the Change of Control
provisions of this Indenture would constitute a violation of any such laws or regulations, the
Company shall comply with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under the Change of Control provisions of this Indenture by virtue of
such compliance.

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

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

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

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

          (c) The Paying Agent shall promptly mail or wire transfer to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate
and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new
Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

          (d) The Company shall publicly announce the results of the Change of Control Offer on or as
soon as practicable after the Change of Control Payment Date.

          (e) If Holders of not less than 95% in aggregate principal amount of the outstanding Notes
validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any
third party making a Change of Control Offer in lieu of the Company as described in this Section
4.13, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company
shall have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more
than 30 days following such purchase pursuant to the Change of Control Offer described in this
Section 4.13, to redeem all Notes that remain outstanding following such purchase at a redemption
price in cash equal to the applicable Change of Control Payment plus, to the extent not included in
the Change of Control Payment, accrued and unpaid interest, if any, and Liquidated Damages, if any
thereon, to the date of redemption.

          (f) Notwithstanding anything to the contrary in this Section 4.13, the Company shall 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 Section 4.13 and all other provisions of this Indenture applicable

Section 4.14. Designation of Restricted and Unrestricted Subsidiaries.

          (a) The Board of Directors of the Company may designate any Restricted Subsidiary of the
Company to be an Unrestricted Subsidiary; provided that:

     (i) any Guarantee by the Company or any Restricted Subsidiary thereof of any
Indebtedness of the Subsidiary being so designated shall be deemed to be an Incurrence of
Indebtedness by the Company or such Restricted Subsidiary (or both, if applicable) at the
time of such designation, and such Incurrence of Indebtedness would be permitted under
Section 4.09;

     (ii) the aggregate Fair Market Value of all outstanding Investments owned by the
Company and its Restricted Subsidiaries in the Subsidiary being so designated (including any
Guarantee by the Company or any Restricted Subsidiary of any Indebtedness of such
Subsidiary) shall be deemed to be a Restricted Investment made as of the time of such
designation and such Investment would be permitted under Section 4.07;

     (iii) such Subsidiary does not hold any Liens on any property of, the Company or any
Restricted Subsidiary thereof;

     (iv) the Subsidiary being so designated:

     (1) is a Person with respect to which neither the Company nor any of its
Restricted Subsidiaries has any direct or indirect obligation (A) to subscribe for
additional Equity Interests or (B) to maintain or preserve such Person’s financial
condition or to cause such Person to achieve any specified levels of operating
results; and

     (2) has not guaranteed or otherwise directly or indirectly provided credit
support for any Indebtedness of the Company or any of its Restricted Subsidiaries,
except to the extent such Guarantee or credit support would be released upon such
designation; and

     (3) has at least one director on its Board of Directors that is not a director
or officer of the Company or any of its Restricted Subsidiaries and has at least one
executive officer that is not a director or officer of the Company or any of its
Restricted Subsidiaries; and

     (v) no Default or Event of Default would be in existence following such designation.

          (b) Any designation of a Restricted Subsidiary of the Company as an Unrestricted Subsidiary
shall be evidenced to the Trustee by filing with the Trustee the Board Resolution giving effect to
such designation and an Officers’ Certificate certifying that such designation complied with the
preceding conditions and was permitted by this Indenture. If, at any time, any Unrestricted
Subsidiary would fail to meet any of the preceding requirements described in subclauses (1) or (2)
of clause (iv) above it shall thereafter cease to be an Unrestricted Subsidiary

69

 

for purposes of
this Indenture and any Indebtedness of such Subsidiary shall be deemed to be Incurred or made by a
Restricted Subsidiary of the Company as of such date and, if such Indebtedness, Investments or
Liens are not permitted to be Incurred or made as of such date under this Indenture, the Company
shall be in default under this Indenture.

          (c) The Board of Directors of the Company may at any time designate any Unrestricted
Subsidiary to be a Restricted Subsidiary; provided that:

     (i) such designation shall be deemed to be an Incurrence of Indebtedness by a
Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
Subsidiary and such designation shall only be permitted if such Indebtedness is permitted
under Section 4.09; and

     (ii) no Default or Event of Default would be in existence following such designation.

Section 4.15. Payments for Consent.

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

Section 4.16. Subsidiary Guarantees.

          (a) If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic
Subsidiary on or after the Issue Date, then that newly acquired or created Domestic Subsidiary must
become a Guarantor and execute a supplemental indenture and deliver an Opinion of Counsel to the
Trustee within 15 Business Days of the date on which it was acquired or created; provided, however,
that a Domestic Subsidiary that owns net assets that have an aggregate fair market value (as
determined in good faith by the Board of Directors of the Company) of less than 5% of the
Consolidated Tangible Assets as of the end of the previous quarter, need not become a Guarantor.

          (b) However, if, as of the end of any fiscal quarter, the Domestic Subsidiaries that are not
Guarantors collectively own net assets that have an aggregate fair market value (as determined in
good faith by the Board of Directors of the Company) equal to or greater than 5% of the
Consolidated Tangible Assets, then the Company shall designate one or more of such non-Guarantor
Domestic Subsidiaries to become Guarantors such that after giving effect to such designation or
designations, as the case may be, the total net assets owned by all such remaining non-Guarantor
Domestic Subsidiaries will have an aggregate fair market value (as determined in good faith by the
Board of Directors of the Company) of less than 5% of the Consolidated Tangible Assets. Any such
Restricted Subsidiary so designated shall become a Guarantor and execute a supplemental indenture
(in substantially the form attached hereto as Exhibit E or in such other form as shall be
acceptable to the Trustee) and deliver an Opinion of Counsel to the Trustee within 15 Business Days
of the date on which it was designated.

issued or by which there may be secured or evidenced any Indebtedness for money borrowed by
the Company or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by
the Company or any of its Restricted Subsidiaries) whether such Indebtedness or Guarantee
now exists, or is created after the Issue Date, if that default:

72

 

     (A) is caused by a failure to make any payment when due at the final maturity
of such Indebtedness (a “Payment Default”); or

     (B) results in the acceleration of such Indebtedness prior to its express
maturity,

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

     (vii) failure by the Company or any of its Restricted Subsidiaries to pay final
judgments (to the extent such judgments are not paid or covered by insurance provided by a
reputable carrier that has the ability to perform and has acknowledged coverage in writing)
aggregating in excess of $15.0 million, which judgments are not paid, discharged or stayed
for a period of 60 days;

     (viii) except as permitted by this Indenture, any Subsidiary Guarantee shall be held in
any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be
in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor,
shall deny or disaffirm its obligations under its Subsidiary Guarantee;

     (ix) the Company, any Guarantor or any Significant Subsidiary of the Company (or any
Restricted Subsidiaries of the Company that together would constitute a Significant
Subsidiary of the Company) pursuant to or within the meaning of Bankruptcy Law:

     (A) commences a voluntary case,

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

     (C) makes a general assignment for the benefit of its creditors, or

     (D) generally is not paying its debts as they become due; and

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

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

     (B) appoints a custodian of the Company, any Guarantor or any Significant

Section 6.02. Acceleration.

          To the extent permitted by applicable law, in the case of an Event of Default specified in
clause (ix) or (x) of Section 6.01(a), with respect to the Company, any Restricted Subsidiary that
is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would
constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately by notice in writing to the Company
specifying the Event of Default.

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

          The Holders of a majority in aggregate principal amount of the Notes then outstanding by
written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an
acceleration and its consequences under the Indenture.

          The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, within
three Business Days after any Officer becomes aware of any Default or Event of Default, an
Officers’ Certificate specifying such Default or Event of Default and what action the Company is
taking or proposes to take with respect thereto.

Section 6.03. Other Remedies.

          (a) If an Event of Default occurs and is continuing, the Trustee may pursue any available
remedy to collect the payment of principal, premium, if any, interest, and Liquidated Damages, if
any, with respect to, the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

          (b) The Trustee may maintain a proceeding even if it does not possess any of the Notes or does
not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a
Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right
or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

74

 

Section 6.04. Waiver of Past Defaults.

          Holders of 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 this Indenture except a continuing Default or Event of Default
in the payment of interest or Liquidated Damages on, or the principal of, the Notes provided,
however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes
may rescind an acceleration and its consequences, including any related payment default that
resulted from such acceleration.

          Upon any such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right consequent thereon

Section 6.05. Control by Majority.

          The Holders of a majority in principal amount of the then outstanding Notes will have the
right to direct the time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee. However, the Trustee may refuse to follow any direction that conflicts
with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in
the giving of such direction and may take any other action it deems proper that is not inconsistent
with any such direction received from Holders of Notes.

Section 6.06. Limitation on Suits.

          (a) A Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

     (i) the Holder gives the Trustee written notice of a continuing Event of Default;

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

     (iii) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee
against any costs, liability or expense;

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

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

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

75

 

Section 6.07. Rights of Holders of Notes to Receive Payment.

          The limitations in Section 6.06 shall not apply to the right of any Holder of a Note to
receive payment of the principal of, premium or Liquidated Damages, if any, or interest on, such
Note or to bring suit for the enforcement of any such payment, on or after the due date expressed
in the Notes, which right shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(a)(i) or (a)(ii) occurs and is continuing,
the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount of principal of, premium, if any, interest, and Liquidated
Damages, if any, remaining unpaid on the Notes and interest on overdue principal and premium, if
any, and, to the extent lawful, interest and Liquidated Damages, if any, and such further amount as
shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim.

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

Section 6.10. Priorities.

          (a) If the Trustee collects any money pursuant to this Article Six, it shall pay out the money
in the following order:

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

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

     Third: to the Company or to such party as a court of competent jurisdiction shall
direct.

          (b) The Trustee may fix a record date and payment date for any payment to Holders of Notes
pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.

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

          The Trustee in its individual or any other capacity may become the owner or pledgee of Notes

same rights it would have if it were not Trustee. However, in the event that the Trustee acquires
any conflicting interest as described in the Trust Indenture Act of 1939 (as in effect at such
time), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue
as trustee (if this Indenture has been qualified under the Trust Indenture Act of 1939) or resign.
Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections
7.10 and 7.11.

Section 7.04. Trustee’s Disclaimer.

          The Trustee shall not be responsible for and makes no representation as to the validity or

days after it occurs. Except in the case of a Default or Event of Default relating to the payment
of principal, premium or interest or Liquidated Damages on any Note, the Trustee may

withhold the

report dated as of such reporting date that complies with TIA Section 313(a) (but if no event
described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date,

also transmit by mail all reports as required by TIA Section 313(c).

          (b) A copy of each report at the time of its mailing to the Holders of Notes shall be mailed
to the Company and filed with the SEC and each stock exchange on which the Notes are listed in
accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes
are listed on any stock exchange or any delisting thereof.

Section 7.07. Compensation and Indemnity.

          (a) The Company shall pay to the Trustee from time to time reasonable compensation for its
acceptance of this Indenture and services provided hereunder. The Trustee’s compensation shall not
be limited by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses
incurred or made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel
and any taxes and other expenses incurred by a trust created pursuant to Section 8.04.

          (b) The Company and the Guarantors shall indemnify the Trustee and its agents against any and
all losses, liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the costs and expenses
of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07)
and defending itself against any claim (whether asserted by either of the Company or any Holder or
any other Person) or liability in connection with the exercise or performance of any of its powers
or duties hereunder, except to the extent any such loss, liability or expense may be attributable
to its negligence, bad faith or willful misconduct. The Trustee shall notify the Company and the
Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder unless the failure to
notify the Company impairs the Company’s ability to defend such claim. The Company shall defend
the claim and the Trustee shall cooperate in the defense. The Company need not pay for any
settlement made without its consent, which consent shall not be unreasonably withheld, conditioned
or delayed.

          (c) The obligations of the Company and the Guarantors under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture and resignation or removal of the Trustee.

80

 

          (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Notes on all money or property held or collected by the
Trustee, except that such Lien shall not apply to money and property held in trust to pay principal
and interest on particular Notes. Such Lien
shall survive the satisfaction and discharge of this Indenture and resignation or removal of
the Trustee.

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

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

Section 7.08. Replacement of Trustee.

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

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

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

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

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

     (iv) the Trustee becomes incapable of acting.

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

          (d) If a successor Trustee does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in
principal amount of the then outstanding Notes may petition at the expense of the Company any court
of competent jurisdiction for the appointment of a successor Trustee.

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

81

 

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

Section 7.09. Successor Trustee by Merger, Etc.

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

Section 7.10. Eligibility; Disqualification.

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

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

Section 7.11. Preferential Collection of Claims Against Company.

          The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in
TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section
311(a) to the extent indicated therein. The Trustee hereby waives any right to set off any claim
that it may have against the Company in any capacity (other than as Trustee and Paying Agent)
against any of the assets of the Company held by the Trustee; provided, however, that if the
Trustee is or becomes a
lender of any other Indebtedness permitted hereunder to be pari passu with the Notes, then
such waiver shall not apply to the extent of such Indebtedness.

DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance.

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

82

 

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 and all obligations of the Guarantors shall be deemed to have been discharged with respect to
their obligations under the Subsidiary Guarantees on the date the conditions set forth below are
satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the
Company and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes and Subsidiary Guarantees, respectively, which shall
thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other
Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense
of the Company, shall execute proper instruments acknowledging the same), except for the following
provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights
of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or
premium and Liquidated Damages, if any, on such Notes when such payments are due from the trust
referred to in Section 8.04, (b) the Company’s obligations pursuant to Sections 2.05, 2.07, 2.08,
2.11 and 4.02, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company’s and the Guarantors’ obligations in connection therewith and (d) the provisions of
this Article Eight related to Legal Defeasance. Subject to compliance with this Article Eight, the
Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its
option under Section 8.03 hereof.

Section 8.03. Covenant Defeasance.

          Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section
8.03, the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth
in Section 8.04 hereof, be released from their obligations under the covenants contained in
Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16 and 5.01(a)(iii) 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 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 and the Subsidiary Guarantees, the Company and the
Guarantors 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, but, except as specified above, the
remainder of this Indenture and such Notes and Subsidiary Guarantees shall be unaffected thereby.
In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this
Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, clauses
(iii) through (vii) of Section

83

 

6.01(a) shall not constitute Events of Default, and clause (ix) of Section 6.01(a) shall not
constitute an Event of Default with respect to the Subsidiaries of the Company only.

Section 8.04. Conditions to Legal or Covenant Defeasance.

          (a) The following shall be the conditions to the application of either Section 8.02 or 8.03 to
the outstanding Notes:

          (i) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a
combination thereof, in such amounts as will be sufficient, in the opinion of a nationally
recognized investment bank, appraisal firm or firm of independent public accountants, to pay
the principal of, or interest and premium and Liquidated Damages, if any, 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 a particular
redemption date;

          (ii) in the case of Legal Defeasance, the Company shall have delivered to the Trustee
an Opinion of Counsel reasonably acceptable to the Trustee confirming that (1) the Company
has received from, or there has been published by, the Internal Revenue Service a ruling or
(2) since 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, 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;

          (iii) in the case of Covenant Defeasance, the Company shall have delivered to the
Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the
Holders of the outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Covenant Defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the
case if such Covenant Defeasance had not occurred;

          (iv) no Default or Event of Default shall have occurred and be continuing (other than a
Default or Event of Default resulting from the borrowing of funds to be applied to such
deposit) either: (1) on the date of such deposit; or (2) insofar as Events of Default from
bankruptcy or insolvency events are concerned, at any time in the period ending on the 123rd
day after the date of deposit;

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

          (vi) in the case of Legal Defeasance, the Company must have delivered to the Trustee an
Opinion of Counsel to the effect that (1) assuming no intervening bankruptcy of the Company
or any Guarantor between the date of deposit and the 123rd day

84

 

following the deposit and assuming that no Holder is an “insider” of the Company under
applicable bankruptcy law, after the 123rd day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors’ rights generally, including Section 547
of the United States Bankruptcy Code and Section 15 of the New York Debtor and Creditor Law,
and (2) the creation of the defeasance trust does not violate the Investment Company Act of
1940;

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

          (viii) the Company must deliver to the Trustee an Officers’ Certificate, stating that
all conditions precedent set forth in clauses (i) through (vii) of this Section 8.04(a) have
been complied with; and

          (ix) the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of
Counsel may be subject to customary assumptions, qualifications and exclusions), stating
that all conditions precedent set forth in clauses (ii) and (iii) of this Section 8.04(a)
have been complied with.

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

          (a) Subject to Section 8.06, all money and non-callable Government Securities (including the
proceeds thereof) deposited with the Trustee pursuant to Section 8.04 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 this Indenture, to the payment, either directly or through any Paying Agent (including
the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of
all sums due and to become due thereon in respect of principal, premium and Liquidated Damages, if
any, and interest, but such money need not be segregated from other funds except to the extent
required by law.

          (b) The Company shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to
Section 8.04 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.

          (c) Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver
or pay to the Company from time to time upon the request of the Company any money or non-callable
Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.04(a)), are in excess
of the amount thereof that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

85

 

Section 8.06. Repayment to the Company.

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

Section 8.07. Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable
Government Securities in accordance with Section 8.02 or 8.03, 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 this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03
and, in the case of a Legal Defeasance, the Guarantors’ obligations under their respective
Subsidiary Guarantees shall be revised and reinstated as though no deposit had occurred pursuant to
Section 8.02, in each case until such time as the Trustee or Paying Agent is permitted to apply all
such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if
the Company makes any payment of principal of, premium or Liquidated Damages, if any, or interest
on any Note following the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the money held by the Trustee or
Paying Agent.

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01. Without Consent of Holders of Notes.

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

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

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

86

 

          (iii) to provide for the assumption of the Company’s or any Guarantor’s obligations to
Holders of Notes in the case of a merger or consolidation or sale of all or substantially
all of the Company’s or such Guarantor’s assets;

          (iv) to make any change that would provide any additional rights or benefits to the
Holders of Notes or that does not materially adversely affect the legal rights under this
Indenture of any such Holder;

          (v) to comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the Trust Indenture Act of 1939;

          (vi) to add any Subsidiary Guarantee or to effect the release of a Guarantor from its

comply with Section 4.16;

          (vii) to secure the Notes or any Subsidiary Guarantees or any other obligation under
this Indenture;

          (viii) to evidence and provide for the acceptance of appointment by a successor

recitation of a provision of this Indenture, the Subsidiary Guarantees or the Notes; or

          (x) to provide for the issuance of Additional Notes in accordance with this Indenture.

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

Section 9.02. With Consent of Holders of Notes.

          (a) Except as otherwise provided in this Section 9.02, the Company, the Guarantors and the
Trustee may amend or supplement this Indenture, the Notes or the Subsidiary Guarantees with the
consent of the Holders of at least a majority in principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Notes), and, subject to Sections 6.04 and 6.07, any existing Default or
Event of Default or compliance with any provision of this Indenture or the

87

 

Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority
in principal amount of the then outstanding Notes (including Additional Notes, if any) (including,
without limitation, consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes).

          (b) 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 indenture supplemental hereto. If a record date
is fixed, the Holders on such record date, or its 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 90 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.

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

          (d) It shall not be necessary for the consent of the Holders of Notes 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.

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

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

          (ii) reduce the principal of or change the fixed maturity of any Note or alter the
provisions, or waive any payment with respect to the redemption of the Notes; provided,
however, that solely for the avoidance of doubt, and without any other implication, any
purchase or repurchase of Notes, including pursuant to 4.10 and 4.13, shall not be deemed a
redemption of the Notes;

88

 

          (iii) reduce the rate of or change the time for payment of interest on any Note;

          (iv) waive a Default or Event of Default in the payment of principal of, or interest or
premium or Liquidated Damages, if any, on the Notes (except a rescission of acceleration of
the Notes by the Holders of at least a majority in aggregate principal amount of the then
outstanding Notes and a waiver of the payment default that resulted from such acceleration);

          (v) make any Note payable in money other than U.S. dollars;

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

          (vii) release any Guarantor from any of its obligations under its Subsidiary Guarantee
or this Indenture, except in accordance with the terms of this Indenture;

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

          (ix) amend or modify any of the provisions of this Indenture or the related definitions
affecting the ranking of the Notes or any Subsidiary Guarantee in any manner adverse to the
Holders of the Notes or any Subsidiary Guarantee; or

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

Section 9.03. Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be set forth in a document
that complies with the TIA as then in effect.

Section 9.04. Revocation and Effect of Consents.

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

Section 9.05. Notation on or Exchange of Notes.

          (a) The Trustee may place an appropriate notation about an amendment, supplement or waiver on
any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee
shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

89

 

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

Section 9.06. Trustee to Sign Amendments, Etc.

          The Trustee shall sign any amendment or supplement to this Indenture or any Note authorized
pursuant to this Article Nine 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 or Note until its Board of Directors approves it. In executing any
amendment or supplement or Note, the Trustee shall be entitled to receive and (subject to Section
7.01) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel
stating that the execution of such amendment or supplement is authorized or permitted by this
Indenture.

ARTICLE TEN

SUBSIDIARY GUARANTEES

Section 10.01. Guarantee.

          (a) Subject to this Article Ten, each of the Guarantors hereby, jointly and severally, and
fully and unconditionally guarantees to each Holder of a Note authenticated and delivered by the
Trustee and to the Trustee and its successors and assigns, irrespective of the validity and
enforceability of, this Indenture, the Notes or the obligations of the Company hereunder or
thereunder, that: (i) the principal of, premium, if any, and interest and Liquidated Damages, if
any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest
and Liquidated Damages, if any, on the Notes, if lawful (subject in all cases to any applicable
grace period provided herein), and all other obligations of the Company to the Holders or the
Trustee hereunder or thereunder will be promptly paid in full, all in accordance with the terms
hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or
any of such other obligations, the same will be promptly paid in full when due in accordance with
the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.
Failing payment when due of any amount so guaranteed 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.

          (b) The Guarantors hereby agree that, to the maximum extent permitted under applicable law,
their obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the
recovery of any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or defense of a
Guarantor. Subject to Section 6.06, to the maximum extent permitted under applicable law, each
Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest, notice and all demands whatsoever and

90

 

covenants that this Subsidiary Guarantee shall not be discharged except by complete
performance of the obligations contained in the Notes and this Indenture.

          (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in
relation to any of the Company or the Guarantors, any amount paid by any of them to the Trustee or
such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated
in full force and effect.

          (d) 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, to the maximum extent
permitted by applicable law, 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 Article Six 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 Article Six 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.

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

Section 10.03. Guarantors May Consolidate, Etc., on Certain Terms.

          (a) Except as provided in Section 10.04 hereof, each Guarantor may not sell or otherwise
dispose of all or substantially all of its assets to, or consolidate with or merge with or into
(regardless of whether such Guarantor is the surviving Person), another Person, other than the
Company or another Guarantor, unless:

91

 

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

          (ii) either:

     (A) the Person acquiring the property in any such sale or disposition or the
Person formed by or surviving any such consolidation or merger (if other than the
Guarantor) is organized or existing under the laws of the United States, any state
thereof or the District of Columbia and assumes all the obligations of that
Guarantor under this Indenture, its Subsidiary Guarantee and the Registration Rights
Agreement pursuant to a supplemental indenture satisfactory to the Trustee; or

     (B) such sale or other disposition or consolidation or merger complies with
Section 4.10.

          (b) In case of any such consolidation, merger, sale or conveyance and upon the assumption by
the successor Person, by supplemental indenture, executed and delivered to the Trustee and
satisfactory in form to the Trustee, of the Subsidiary Guarantee and the due and punctual
performance of all of the covenants and conditions of this Indenture to be performed by a
Guarantor, such successor Person shall succeed to and be substituted for a Guarantor with the same
effect as if it had been named herein as a Guarantor.

          (c) Except as set forth in Article Five, and notwithstanding clauses (i) and (ii) of Section
10.03(a), nothing contained in this Indenture or in any of the Notes shall prevent any
consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall
prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an
entirety to the Company or another Guarantor.

Section 10.04. Release of Guarantor.

          (a) The Subsidiary Guarantee of a Guarantor will be released: (i) 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 Restricted Subsidiary of the Company, if the sale or other
disposition does not violate Section 4.10; (ii) in connection with any sale or other disposition of
all of the Capital Stock of a Guarantor to a Person that is not (either before or after giving
effect to such transaction) a Restricted Subsidiary of the Company, if the sale of all such Capital
Stock of that Guarantor complies with Section 4.10; (iii) if the Company properly designates any
Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary under this Indenture; or
(iv) upon Legal Defeasance or satisfaction and discharge of this Indenture as provided under
Article Eight and Section 11.01, respectively. Upon delivery by the Company to the Trustee of an
Officers’ Certificate and an Opinion of Counsel to the effect that one of the foregoing
requirements has been satisfied and the conditions to the release of a Guarantor under this Section
10.04 have been met, the Trustee shall execute any documents reasonably required in order to
evidence the release of such Guarantor from its obligations under its Subsidiary Guarantee.

92

 

          (b) Any Guarantor not released from its obligations under its Subsidiary Guarantee shall
remain liable for the full amount of principal of and interest and Liquidated Damages, if any, on
the Notes and for the other obligations of any Guarantor under this Indenture as provided in this
Article Ten.

Section 10.05. Execution and Delivery of Notation of Subsidiary Guarantee.

          (a) To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Guarantor
hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as
Exhibit F hereto will be endorsed by an Officer of such Guarantor on each Note
authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of
such Guarantor by one of its Officers.

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

          (c) If an Officer whose signature is on this Indenture or on the Subsidiary Guarantee no
longer holds that office at the time the Trustee authenticates the Note on which a Subsidiary
Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

          (d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, will
constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the
Guarantors.

SATISFACTION AND DISCHARGE

Section 11.01. Satisfaction and Discharge.

          (a) This Indenture shall be discharged and shall cease to be of further effect as to all Notes
issued hereunder, when:

          (i) either:

     (A) all Notes that have been authenticated (except lost, stolen or destroyed
Notes that have been replaced or paid and Notes for whose payment money has
theretofore been deposited in trust and thereafter repaid to the Company) have been
delivered to the Trustee for cancellation; or

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

93

 

          the Trustee for cancellation for principal, premium and Liquidated Damages, if any, and accrued
interest to the date of maturity or redemption;

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

          (iii) such deposit will not result in a breach or violation of, or constitute a default
under, any material agreement or instrument (other than this Indenture) to which the Company
or any Guarantor is a party or by which the Company or any Guarantor is bound;

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

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

               (b) In addition, the Company must deliver to the Trustee (a) an Officers’ Certificate, stating
that all conditions precedent set forth in clauses (i) through (v) of Section 11.01(a) above have
been satisfied, and (b) an Opinion of Counsel (which Opinion of Counsel may be subject to customary
assumptions and qualifications), stating that all conditions precedent set forth in clauses (iii)
and (v) of Section 11.01(a) above have been satisfied; provided that the Opinion of Counsel with
respect to clause (iii) of Section 11.01(a) above may be to the knowledge of such counsel.

               (c) Notwithstanding the above, the Trustee shall pay to the Company from time to time upon its
request any cash or Government Securities held by it as provided in this section which, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written
certification delivered to the Trustee, are in excess of the amount thereof that would then be
required to be deposited to effect a satisfaction and discharge under this Article Eleven.

               (d) After the conditions to discharge contained in this Article Eleven have been satisfied,
and the Company has paid or caused to be paid all other sums payable hereunder by the Company, the
Trustee upon written request shall acknowledge in writing the discharge of the obligations of the
Company and the Guarantors under this Indenture (except for those surviving obligations specified
in Section 11.04).

Section 11.02. Deposited Money and Government Securities to Be Held in Trust; Other
Miscellaneous Provisions.

               Subject to Section 11.03 hereof, all money and non-callable Government Securities (including
the proceeds thereof) deposited with 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 this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as Paying Agent) as the Trustee

94

 

may determine, to the Holders of such Notes of all sums due and to become due thereon in
respect of principal, premium and Liquidated Damages, if any, and interest, but such money need not
be segregated from other funds except to the extent required by law.

Section 11.03. Repayment to the Company.

               Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, premium and Liquidated Damages, if any, or interest on
any Note and remaining unclaimed for two years after such principal, and premium or Liquidated
Damages, 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 of such Note
shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, 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 or The Wall Street Journal (national edition), notice that such money
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 money then
remaining shall be repaid to the Company.

Section 11.04. Survival.

Trustee for the benefit of the Holders pursuant to Section 11.01(a) hereof, prior to the date of
maturity or redemption, as the case may be, the following provisions of this Indenture shall
survive until otherwise terminated or discharged hereunder:

principal of, premium, if any, interest and Liquidated Damages, if any, on such Notes when
such payments are due from the trust;

4.02 hereof;

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

Section 11.05. Reinstatement.

               If the Trustee or Paying Agent is unable to apply any Government Securities in accordance with
Section 11.02 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 this Indenture and the Notes shall be revived and reinstated as though
no deposit had occurred pursuant to Section 11.01(a)(2) hereof until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section 11.02 hereof;
provided, however, that, if the Company makes any payment of

95

 

principal of, premium, if any, interest and Liquidated Damages, if any, on any Note following
the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders
of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Section 12.14. Acts of Holders.

               (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by the Holders may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such Holders in person or by
agents duly appointed in writing; and, except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments are delivered to the Trustee and, where
it is hereby expressly required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the
Holders signing such instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this Indenture and
conclusive in favor of the Trustee and the Company if made in the manner provided in this Section
12.14.

               (b) The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to such witness, notary or officer the execution
thereof. Where such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The
fact and date of the execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which the Trustee deems sufficient.

               (c) Notwithstanding anything to the contrary contained in this Section 12.14, the principal
amount and serial numbers of Notes held by any Holder, and the date of holding the same, shall be
proved by the register of the Notes maintained by the Registrar as provided in Section 2.04.

               (d) If the Company shall solicit from the Holders of the Notes any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by
or pursuant to a resolution of its Board of Directors, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding
TIA Section 316(c), such record date shall be the record date specified in or pursuant to such
resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation
of Holders generally in connection therewith or the date of the most recent list of Holders
forwarded to the Trustee prior to such solicitation pursuant to Section 2.06 and not later than the
date such solicitation is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of
the then outstanding Notes have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the then
outstanding Notes shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed effective

100

 

unless it shall become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.

               (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the
Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note
issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance
thereon, whether or not notation of such action is made upon such Note.

               (f) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder
with regard to any particular Note may do so itself with regard to all or any part of the principal

[Reverse Side of Note]

ALLIS-CHALMERS ENERGY INC.

9.0% Senior Notes due 2014

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

          1. Interest. The Company promises to pay interest on the principal amount of this Note at
9.0% per annum until maturity and shall pay the Liquidated Damages, if any, payable pursuant to
Section 5 of the Registration Rights Agreement referred to below. The Company shall pay interest
and Liquidated Damages, if any, semi-annually in arrears on January 15 and July 15 of each year, or
if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest
Payment Date”). Interest on overdue principal and interest and Liquidated Damages, if any, will
accrue at the applicable interest rate on the Notes. Interest on the Notes will accrue from the
most recent date to which interest has been paid or, if no interest has been paid, from the date of
issuance; provided that if there is no existing Default in the payment of interest, and if this
Note is authenticated between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date;
provided further that the first Interest Payment Date shall be July 15, 2006. The Company shall
pay interest on overdue principal at the rate borne by the Notes, and it shall pay interest on
overdue installments of interest at the same rate to the extent lawful. Interest shall be computed
on the basis of a 360-day year comprised of twelve 30-day months. If an Interest Payment Date
falls on a day that is not a Business Day, the interest payment to be made on such Interest Payment
Date will be made on the next succeeding Business Day with the same force and effect as if made on
such Interest Payment Date, and no additional interest will accrue as a result of such delayed
payment.

          2. Method of Payment. The Company shall pay interest on the Notes (except defaulted interest)
and Liquidated Damages, if any, to the Persons who are registered Holders of Notes at the close of
business on the January 1 or July 1 next preceding the Interest Payment Date, even if such Notes
are canceled after such record date and on or before such Interest Payment Date, except as provided
in Section 2.13 of the Indenture with respect to defaulted interest. The Notes will be payable as
to principal, premium, Liquidated Damages, if any, and interest at the office or agency of the
Paying Agent and Registrar within the City and State of New York, or, at the option of the Company,
payment of interest and Liquidated Damages, if any, may be made by check mailed to the Holders at
their addresses set forth in the register of Holders; provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and interest, premium and
Liquidated Damages, if any, on, all Global Notes and all other Notes the Holders of which will have
provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in
such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts.

A-6

 

          3. Paying Agent and Registrar. Initially, the Trustee under the Indenture shall act as Paying
Agent and Registrar. The Company may change any Paying Agent or Registrar without prior notice to
any Holder. The Company or any of its Subsidiaries may act in any such capacity.

          4. Indenture. The Company issued the Notes under an Indenture dated as of January 18, 2006
among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939,
as amended. 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. The Indenture pursuant to which this Note is issued provides that an unlimited
aggregate principal amount of Additional Notes may be issued thereunder.

          5. Optional Redemption. (a) Except as set forth in paragraphs 5(b) and (c) below, the
Company shall not have the option to redeem the Notes prior to January 15, 2010. On or after
January 15, 2010 the Company may redeem all or a portion of the Notes upon not less than 30 days’
nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest and Liquidated Damages, if any, to the
applicable redemption date, if redeemed during the twelve-month period beginning on January 15 of
the years indicated below, subject to the rights of Holders on the relevant record date to receive
interest on the relevant Interest Payment Date:

	 	 	 	 	 
	Year

	 	Percentage

	2010

	 	 	104.500	%
	2011

	 	 	102.250	%
	2012 and thereafter

	 	 	100.000	%

          (b) At any time prior to January 15, 2009, the Company may, on one or more occasions, redeem
up to 35% of the aggregate principal amount of Notes issued under the Indenture (including any
Additional Notes) at a redemption price of 109.000% of the principal amount thereof, plus accrued
and unpaid interest and Liquidated Damages, if any, to the redemption date, with the net cash
proceeds of one or more Equity Offerings; provided that (1) at least 65% of the aggregate principal
amount of Notes issued under the Indenture on the Issue Date remains outstanding immediately after
the occurrence of such redemption (excluding Notes held by the Company or its Affiliates); and (2)
the redemption must occur within 180 days of the date of the closing of such Equity Offering.

          (c) At any time prior to January 15, 2010, the Company may redeem the Notes, in whole or in
part, at the Make-Whole Price, plus accrued and unpaid interest and Liquidated Damages, if any, to
the redemption date. “Make-Whole Price” with respect to a Note means the greater of:

          (1) the sum of the outstanding principal amount and Make-Whole Amount of such Note; and

A-7

 

          (2) the redemption price of such Note on January 15, 2010, determined pursuant to the
Indenture (104.500% of the principal amount).

          “Make-Whole Amount” with respect to a Note means an amount equal to the excess, if any, of:

          (1) the present value of the remaining interest, premium, if any, and principal payments due
on such Note as if such Note were redeemed on January 15, 2010 computed using a discount rate equal
to the Treasury Rate plus 50 basis points, over

          (2) the outstanding principal amount of such Note.

          “Treasury Rate” means the yield to maturity at the time of the computation of United States
Treasury securities with a constant maturity (as compiled by and published in the most recent
Federal Reserve Statistical Release H.15(519), which has become publicly available at least two
business days prior to the date of the redemption notice or, if such Statistical Release is no
longer published, any publicly available source of similar market date) most nearly equal to the
then remaining maturity of the Notes assuming redemption of the Notes on January 15, 2010;
provided, however, that if the Make-Whole Average Life of such Notes is not equal to the constant
maturity of the United States Treasury security for which a weekly average yield is given, the
Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a
year) from the weekly average yields of United States Treasury securities for which such yields are
given, except that if the Make-Whole Average Life of such Notes is less than one year, the weekly
average yield on actually traded United States Treasury securities adjusted to a constant maturity
of one year shall be used. “Make-Whole Average Life” means the number of years (calculated to the
nearest one-twelfth) between the date of redemption and January 15, 2010.

          6. Repurchase at Option of Holder. (a) If a Change of Control occurs, each Holder of Notes
shall have the right to require the Company to repurchase all or any part (equal to $2,000 and
integral multiples of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer (a
“Change of Control Offer”) on the terms set forth in the Indenture. In the Change of Control
Offer, the Company will offer a payment (a “Change of Control Payment”) in cash equal to not less
than 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of repurchase (the “Change of Control Payment Date,”
which date shall be no earlier than the date of such Change of Control). No later than 30 days
following any Change of Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering to repurchase Notes
on the Change of Control Payment Date specified in such notice, which date shall be no earlier than
30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures
required by the Indenture and described in such notice.

          (b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales,
within 10 Business Days of each date on which the aggregate amount of Excess Proceeds exceeds $10.0
million, the Company shall make an offer (an “Asset Sale Offer”) to all Holders of Notes and all
holders of other Indebtedness that is pari passu with the Notes

A-8

 

containing provisions similar to those set forth in the Indenture with respect to offers to
purchase or redeem with the proceeds of sales of assets, in accordance with Section 4.10 of the
Indenture, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be
equal to 100% of principal amount plus accrued and unpaid interest and Liquidated Damages, if any,
to the date of purchase, and will be payable in cash, all in accordance with the procedures set
forth in the Indenture. If any Excess Proceeds remain unapplied after consummation of an Asset
Sale Offer, the Company and its Restricted Subsidiaries may use those Excess Proceeds for any
purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and
other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased
on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive
notice of an Asset Sale Offer from the Company prior to any related purchase date and may elect to
have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase”
attached to this Note. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds
shall be reset at zero.

          7. Denominations, Transfer, Exchange. The Notes are in registered form without interest
coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. 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 is not required to transfer or exchange
any Note selected for redemption. Also, the Company is not required to (1) to issue, to register
the transfer of or to exchange any Notes during a period beginning at the opening of business 15
days before the day of any selection of Notes for redemption under Section 3.02 under the Indenture
and ending at the close of business on the day of selection, (2) to register the transfer of or to
exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part, (3) to register the transfer of or to exchange a Note between a
record date and the next succeeding interest payment date or (4) to register the transfer of or to
exchange a Note tendered and not withdrawn in connection with a Change of Control Offer or an Asset
Sale Offer. Transfer may be restricted as provided in the Indenture.

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

          9. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes
may be amended or supplemented with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing
default or compliance with any provision of the Indenture or the Notes may be waived with the
consent of the Holders of a majority in principal amount of the then outstanding Notes (including,
without limitation, consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes). Without the consent of any Holder of a Note, the Indenture or the Notes may be
amended or supplemented to, among other things, cure any

A-9

 

ambiguity, defect or inconsistency, or make any change that does not adversely affect the
legal rights under the Indenture of any such Holder.

          10. Defaults and Remedies. To the extent permitted by applicable law, in the case of an Event
of Default arising from events of bankruptcy or insolvency specified in clause (ix) or (x) of
Section 6.01(a) of the Indenture, with respect to the Company, any Restricted Subsidiary that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would
constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately by notice in writing to the Company
specifying the Event of Default. Holders of the Notes may not enforce the Indenture or the Notes
except as provided in the Indenture. Subject to certain limitations, Holders of a majority in
principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders of the Notes notice of any Default or Event of
Default (except a Default or Event of Default relating to the payment of principal, premium or
interest or Liquidated Damages) if and so long as a committee of its Responsible Officers in good
faith determines that withholding the notice is in the interests of the Holders of the Notes. The
Holders of 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 or Liquidated Damages on, or the principal of, the Notes. The Holders
of a majority in principal amount of the then outstanding Notes will have the right to direct the
time, method and place of conducting any proceeding for exercising any remedy available to the
Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the
Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in
good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of
such direction and may take any other action it deems proper that is not inconsistent with any such
direction received from Holders of Notes.

          11. Trustee Dealings with Company. The Trustee in its individual or any other capacity may
become the owner or pledgee of Notes and may become a creditor of, or otherwise deal with the
Company or any of its Affiliates, with the same rights it would have if it were not Trustee.

          12. No Recourse Against Others. No director, officer, employee, incorporator, stockholder,
member, manager or partners of the Company or any Guarantor, as such, shall have any liability for
any obligations of the Company or the Guarantors under the Notes, the Indenture, the Subsidiary
Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of Notes by accepting a Note waives and releases all such liability. This
