provisions of this Indenture, or as may be required by the Custodian, the Depositary or by the

Note to reflect the amount of any increase or decrease in the Principal Amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee,

payable to the Person to whom the Principal Amount is payable and (ii) the Interest payable upon

pursuant to such redemption or repurchase (unless the Redemption Date or the Repurchase Date, as
the case may be, is after a Regular Record Date and on or prior to the corresponding Interest
Payment Date, in which case the semi-annual payment of interest becoming due on such date shall be
payable to the holders of such Notes registered as such on the applicable Regular Record Date).

funds, if such Person is entitled to Interest on Notes with an aggregate Principal Amount in excess
of $2,000,000) (provided that at the Stated Maturity, Interest on any Note will be payable with the
Principal Amount at the Company’s office or agency in New York City) or (ii) on any Global Note by
wire transfer of immediately available funds to the account of the Depositary or its nominee.

Any Interest on any Note which is payable, but is not punctually paid or duly provided for, on
any December 15 or June 15 (herein called “Defaulted Interest”) shall forthwith cease to be payable
to the Noteholder on the relevant Regular Record Date by virtue of its having been such Noteholder,
and such Defaulted Interest shall be paid by the Company and the Issuer, at its election in each
case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Notes (or their respective Predecessor Notes) are registered at 5:00 p.m., New York City
time, on a “Special Record Date” for the payment of such Defaulted Interest, which shall be the
date fixed in the following manner. 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 (which
shall be not less than twenty-five days after the receipt by the Trustee of such notice, unless the
Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the
date of the proposed payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more
than fifteen days and not less than ten days prior to the date of the proposed payment, and not
less than ten days after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and
the Special Record Date therefor to be mailed, first-class postage prepaid, to each holder at his
address as it appears in the Note Register, not less than ten days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names
the Notes (or their respective Predecessor Notes) are registered at 5:00 p.m., New York City time,
on such Special Record Date and shall no longer be payable pursuant to the following clause (2) of
this Section 2.03.

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not
inconsistent with the requirements of any securities exchange or automated quotation system on
which the Notes may be listed or designated for issuance, and upon such notice as may be required
by such exchange or automated quotation system, if, after notice given by the Company to the
Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Trustee.

Section 2.04. Execution of Notes. The Notes shall be signed in the name and on behalf of the
Company by the manual or facsimile signature of its Chief Executive Officer, President, Chief
Operating Officer, Chief Financial Officer or any Vice President (whether or not designated by a

Notes as shall bear thereon a certificate of authentication substantially in the form set forth on
the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an
authenticating agent appointed by the Trustee as provided by Section 16.11), shall be entitled to
the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the
Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive
evidence that the Note so authenticated has been duly authenticated and delivered hereunder and
that the holder is entitled to the benefits of this Indenture.

In case any officer of the Company who shall have signed any of the Notes shall cease to be
such officer before the Notes so signed shall have been authenticated and delivered by the Trustee,
or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or
disposed of as though the person who signed such Notes had not ceased to be such officer of the
Company, and any Note may be signed on behalf of the Company by such persons as, at the actual date
of the execution of such Note, shall be the proper officers of the Company, although at the date of
the execution of this Indenture any such person was not such an officer.

exchanged in part, either such Global Note shall be so surrendered for exchange or, if the
Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global
Note, the Principal Amount thereof shall be reduced, by an amount equal to the portion
thereof to be so exchanged, by means of an appropriate adjustment made on the records of the
Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make
available for delivery the Note issuable on such exchange to or upon the written order of
the Depositary or an authorized representative thereof.

(iv) In the event of the occurrence of any of the events specified in clause (ii)
above, the Company will promptly make available to the Trustee a reasonable supply of
certificated Notes in definitive, fully registered form, without interest coupons.

(v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor
any other Persons on whose behalf Agent Members may act shall have any rights under this
Indenture with respect to any Global Note registered in the name of the Depositary or any
nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by
the Company, the Issuer, the Subsidiary Guarantors, the Trustee and any agent of the
Company, the Issuer, the Subsidiary Guarantors or the Trustee as the absolute owner and
holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Issuer, the Subsidiary Guarantors, the Trustee
or any agent of the Company, the Issuer, the Subsidiary Guarantors or the Trustee from
giving effect to any written certification, proxy or other authorization furnished by the
Depositary or such nominee, as the case may be, or impair, as between the Depositary, its
Agent Members and any other Person on whose behalf an Agent Member may act, the operation of
customary practices of such Persons governing the exercise of the rights of a beneficial
holder of any Note.

(vi) At such time as all interests in a Global Note have been redeemed, repurchased,
canceled or exchanged for Notes in certificated form, such Global Note shall, upon receipt
thereof, be canceled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Custodian. At any time prior to such cancellation,
if any interest in a Global Note is redeemed, repurchased, canceled or exchanged for Notes
in certificated form, the Principal Amount of such Global Note shall, in accordance with the
standing procedures and instructions existing between the Depositary and the Custodian, be
appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee
or the Custodian, at the direction of the Trustee, to reflect such reduction.

(c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set
forth in this Section 2.05(c) (together with any Common Stock issued upon exchange of the Notes
bearing such legend and required to bear the legend set forth in Exhibit B, collectively, the
“Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section
2.05(c) (including those set forth in the legend below) unless such restrictions on transfer shall
be waived by written consent of the Company, and the holder of each such Restricted Security, by
such holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used
in Section 2.05(c) and 2.05(d), the term “transfer” encompasses any sale, pledge, loan, transfer or
other disposition whatsoever of any Restricted Security or any interest therein.

Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under
the Securities Act (or any successor provision), any certificate evidencing such Note (and all
securities issued in exchange therefor or substitution thereof, other than Common Stock, if any,
issued upon exchange thereof, which shall bear the legend set forth in Exhibit B, if applicable)
shall bear a legend in substantially the following form, unless such Note has been sold pursuant to
a registration statement that has been declared effective under the Securities Act (and which
continues to be effective at the time of such transfer) or pursuant to Rule 144 under the
Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in
writing, with written notice thereof to the Trustee:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY
INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED
OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT
FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF:

(1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT (“RULE 144A”)) AND IS PURCHASING IN COMPLIANCE WITH RULE 144A UNDER
THE SECURITIES ACT;

(2) AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS
PURCHASED SECURITIES THAT IT WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS
SECURITY OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY OR ANY COMMON STOCK ISSUABLE UPON
EXCHANGE OF SUCH SECURITY EXCEPT (A) TO CSK AUTO, INC. (THE “ISSUER”) OR ANY SUBSIDIARY
THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE
SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER, (C) TO A
QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A OR (D) PURSUANT TO THE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT PROVIDED BY RULE 144 UNDER THE
SECURITIES ACT (IF AVAILABLE); AND

(3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED
(OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(B) OR 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE
EFFECT OF THIS LEGEND.

IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF
SUCH SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(B) ABOVE), THE HOLDER MUST CHECK THE
APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT
THIS CERTIFICATE TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED
TRANSFER IS PURSUANT TO CLAUSE 2(D) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
INFORMATION AS THE ISSUER OR THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS
BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER
OF THIS SECURITY PURSUANT TO CLAUSE 2(B) OR 2(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE
ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY.

Each stock certificate representing Common Stock issued upon exchange of a Note bearing the
legend set forth in this Section 2.05(c) shall bear a comparable legend as set forth in Exhibit B.

Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms or as to conditions for
removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such
Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be
exchanged for a new Note or Notes, of like tenor and aggregate Principal Amount, which shall not
bear the restrictive legend required by this Section 2.05(c). If the Restricted Security
surrendered for exchange is represented by a Global Note bearing the legend set forth in this
Section 2.05(c), the Principal Amount of the legended Global Note shall be reduced by the
appropriate Principal Amount and the Principal Amount of a Global Note without the legend set forth
in this Section 2.05(c) shall be increased by an equal Principal Amount. If a Global Note without
the legend set forth in this Section 2.05(c) is not then outstanding, the Company shall execute and
the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

(d) Any Note or Common Stock issued upon the exchange of a Note that, prior to the expiration
of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or
any successor provision), is purchased or owned by the Company, the Issuer or any Affiliate thereof
may not be resold by the Company, the Issuer or such Affiliate unless registered under the
Securities Act or resold pursuant to an exemption from the registration requirements of the
Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no
longer being “restricted securities” (as defined under Rule 144).

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

Neither the Trustee nor any agent of the Trustee shall have any responsibility for actions
taken or not taken by the Depositary.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its
written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate
and make available for delivery, a new Note, bearing a number not contemporaneously outstanding, in
exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so
destroyed, lost or stolen. In every case, the applicant for a substituted Note shall furnish to
the Company, to the Trustee and, if applicable, to such authenticating agent such security or
indemnity satisfactory to them to save each of them harmless for any loss, claim, damage,
liability, cost or expense caused by or connected with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or
theft of such Note and of the ownership thereof.

Following receipt by the Trustee or such authenticating agent, as the case may be, of
satisfactory security or indemnity and evidence, as described in the preceding paragraph, the
Trustee or such authenticating agent may authenticate any such substituted Note and make available
for delivery such Note. Upon the issuance of any substituted Note, the Company may require the
payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge
that may be imposed in relation thereto and any other expenses connected therewith. In case any
Note which has matured or is about to mature or has been called for redemption or has been tendered
for repurchase upon a Fundamental Change (and not withdrawn) or has been surrendered for repurchase
on a Repurchase Date (and not withdrawn) or is to be exchanged into cash or combination of cash and
Common Stock, as the case may be, shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substitute Note, pay or authorize the payment of or exchange or
authorize the exchange of the same (without surrender thereof except in the case of a mutilated
Note), as the case may be, if the applicant for such payment or exchange shall furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
satisfactory to them to save each of them harmless from any loss, claim, damage, liability, cost or
expense caused by or in connection with such substitution, and, in every case of destruction, loss
or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any
Paying Agent or Exchange Agent evidence to their satisfaction of the destruction, loss or theft of
such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the
fact that any Note is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the replacement or payment or
conversion or redemption or repurchase of mutilated, destroyed, lost or stolen Notes and shall
preclude any and all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment or conversion or
redemption or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the
Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon
the written request of the Company, authenticate and deliver temporary Notes (printed or
lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially
in the form of the Notes in certificated form, but with such omissions, insertions and variations
as may be appropriate for temporary Notes, all as may be determined by the Company. Every such
temporary Note shall be executed by the Company and authenticated by the Trustee or such
authenticating agent upon the same conditions and in substantially the same manner, and with the
same effect, as the Notes in certificated form. Without unreasonable delay, the Company will
execute and deliver to the Trustee or such authenticating agent Notes in certificated form and
thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or
agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating
agent shall authenticate and make available for delivery in exchange for such temporary Notes an
equal aggregate Principal Amount of Notes in certificated form. Such exchange shall be made by the
Company at its own expense and without any charge therefor. Until so exchanged, the temporary
Notes shall in all respects be entitled to the same benefits and subject to the same limitations
under this Indenture as Notes in certificated form authenticated and delivered hereunder.

Section 2.08. Cancellation of Notes. All Notes surrendered for the purpose of payment,
redemption, repurchase, exchange or registration of transfer shall, if surrendered to the Company
or any Paying Agent or any Note Registrar or any Exchange Agent, be surrendered to the Trustee and
promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and
no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of
this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary
procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as a
redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and
until the same are delivered to the Trustee for cancellation.

Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” or “ISIN”
numbers and/or similar numbers (if then generally in use), and, if so, the Trustee shall use
“CUSIP” and/or “ISIN” numbers in notices of redemption as a convenience to Noteholders; provided
that any such notice may state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Notes, and any such redemption
shall not be affected by any defect in or omission of such numbers. The Company will promptly
notify the Trustee in writing of any change in the “CUSIP” and/or similar numbers.

Section 2.10. Ranking. The indebtedness of the Company arising under or in connection with
this Indenture and every outstanding Note issued under this Indenture from time to time constitutes
and will constitute a direct and senior general obligation of the Company ranking equally with
other existing and future senior Indebtedness of the Company, and shall rank senior in right of
payment to existing and future Indebtedness of the Company and the Issuer that is expressly made
subordinate to the Notes by the terms of such Indebtedness. Additionally, the Notes shall
constitute Senior Debt for purposes of the Senior Subordinated Indenture, and the Notes shall be
deemed to be Designated Senior Debt (as defined in the Senior Subordinated Indenture) at such time
as there does not exist a Credit Agreement (as defined in the Senior Subordinated Indenture). For
purposes of this Section 2.10 only, “Indebtedness” means, without duplication, the principal or
face amount of (i) all obligations for borrowed money, (ii) all obligations evidenced by notes or
other similar instruments, (iii) all obligations in respect of letters of credit or bankers
acceptances or similar instruments (or reimbursement obligations with respect thereto), (iv) all
obligations to pay the deferred purchase price of property or services, (v) all obligations as
lessee which are capitalized in accordance with generally accepted accounting principles, and (vi)
all Indebtedness of others guaranteed by the Company or for which the Company is legally
responsible or liable (whether by agreement to purchase indebtedness of, or to supply funds or to
invest in, others).

ARTICLE 3

Redemption and Repurchase of Notes

Section 3.01. Company’s Right to Redeem. Prior to December 15, 2010, the Notes will not be
redeemable at the Company’s option. At any time on or after December 15, 2010, the Company, at its
option, may redeem the Notes, in whole or in part, in accordance with the provisions of Section
3.02, Section 3.03 and Section 3.04 on the Redemption Date for a redemption price in cash equal to
100% of the Principal Amount of the Notes to be redeemed (the “Redemption Price”), plus any accrued
and unpaid Interest on the Notes redeemed to, but not including, the Redemption Date. If the
Redemption Date is after a Regular Record Date and on or prior to the corresponding Interest
Payment Date, the Interest payable on such Interest Payment Date will be paid on the Redemption
Date to the holder on the Regular Record Date.

Section 3.02. Notice of Optional Redemption; Selection of Notes.

(a) In case the Company shall desire to exercise the right to redeem all or, as the case may
be, any part of the Notes pursuant to Section 3.01, it shall fix a date for redemption (the
“Redemption Date”) and it or, at its written request received by the Trustee not fewer than ten
Business Days prior (or such shorter period of time as may be acceptable to the Trustee) to the
date the notice (which notice shall be prepared by the Company) of such redemption (the “Redemption
Notice”) is to be mailed, the Trustee in the name of and at the expense of the Company, shall mail
or cause to be mailed (or, if The Depository Trust Company is the sole holder of Notes, sent via
electronic mail) the Redemption Notice not fewer than 35 calendar nor more than 60 calendar days
prior to the Redemption Date to each holder of Notes so to be redeemed as a whole or in part at its
last address as the same appears on the Note Register; provided that if the Company shall give such
notice, it shall also give written notice of the Redemption Date to the Trustee. Such mailing
shall be by first class mail. The notice, if mailed in the manner herein provided, shall be
conclusively presumed to have been duly given, whether or not the holder receives such notice. In
any case, failure to give such notice by mail or any defect in the notice to the holder of any Note
designated for redemption as a whole or in part shall not affect the validity of the proceedings
for the redemption of any other Note. Concurrently with the mailing of any such Redemption Notice,
the Company shall issue a press release announcing such redemption, the form and content of which
press release shall be determined by the Company in its sole discretion. The failure to issue any
such press release or any defect therein shall not affect the validity of the Redemption Notice or
any of the proceedings for the redemption of any Note called for redemption.

(b) Each such Redemption Notice shall specify:

(i) the aggregate Principal Amount of Notes to be redeemed;

(ii) the CUSIP, ISIN or similar number or numbers of the Notes being redeemed (if then
generally in use);

(iii) the Redemption Date (which shall be a Business Day);

(iv) the Redemption Price at which Notes are to be redeemed;

(v) the place or places of payment and that payment will be made upon presentation and
surrender of such Notes;

(vi) that Interest accrued to the Redemption Date will be paid as specified in said
notice, and that on and after said date Interest thereon or on the portion thereof to be
redeemed will cease to accrue;

(vii) that the holder has the right to exchange the Notes called for redemption;

(viii) the Exchange Rate on the date of such notice;

(ix) the time and the date on which the right to exchange such Notes or portions
thereof into Common Stock will expire; and

(x) that the Company will pay cash for fractional interests in shares of Common Stock,
if any, as provided in this Indenture.

If fewer than all the Notes are to be redeemed, the Redemption Notice shall identify the Notes to
be redeemed (including CUSIP, ISIN or similar numbers, if any). In case any Note is to be redeemed
in part only, the Redemption Notice shall state the portion of the Principal Amount thereof to be
redeemed and shall state that, on and after the Redemption Date, upon surrender of such Note, a new
Note or Notes in Principal Amount equal to the unredeemed portion thereof will be issued.

(c) On or prior to the Redemption Date specified in the Redemption Notice given as provided in
this Section 3.02, the Company will deposit with the Paying Agent (or, if the Company, the Issuer
or a Subsidiary Guarantors is acting as Paying Agent, set aside, segregate and hold in trust as
provided in Section 4.04) an amount of money in immediately available funds sufficient to redeem on
the Redemption Date all the Notes (or portions thereof) so called for redemption (other than those
theretofore surrendered for exchange into Common Stock) at the Redemption Price plus accrued and
unpaid interest to, but excluding, the Redemption Date; provided that if such payment is made on
the Redemption Date, it must be received by the Paying Agent by 10:00 a.m., New York City time, on
such date. The Company shall be entitled to retain any interest, yield or gain on amounts
deposited with the Paying Agent pursuant to this Section 3.02(c) in excess of amounts required
hereunder to pay the Redemption Price and accrued interest to, but not including, the Redemption
Date. Subject to the last sentence of Section 7.05, if any Note called for redemption is exchanged
pursuant hereto prior to such Redemption Date, any money deposited with the Paying Agent or so
segregated and held in trust for the redemption of such Note shall be paid to the Company upon its
written request, or, if then held by the Company, the Issuer or any of the Subsidiary Guarantors,
shall be discharged from such trust.

Whenever any Notes are to be redeemed, the Company will give the Trustee written notice in the
form of an Officers’ Certificate as to the aggregate Principal Amount of Notes to be redeemed not
fewer than 10 Business Days (or such shorter period of time as may be acceptable to the Trustee)
prior to the mailing of the Redemption Notice to the holders.

(d) If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the
Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in
Principal Amounts of $1,000 or integral multiples thereof) by lot, on a pro rata basis or by
another method the Trustee deems fair and appropriate. If any Note selected for partial redemption
is submitted for exchange in part after such selection, the portion of such Note submitted for
exchange shall be deemed (so far as may be possible) to be from the portion selected for
redemption. The Notes (or portions thereof) so selected shall be deemed duly selected for
redemption for all purposes hereof, notwithstanding that any such Note is submitted for exchange in
part before the mailing of the Redemption Notice.

Upon any redemption of less than all of the outstanding Notes, the Company and the Trustee may
(but need not), solely for purposes of determining the pro rata allocation among such Notes as are
not exchanged and outstanding at the time of redemption, treat as outstanding any Notes surrendered
for exchange during the period of fifteen days next preceding the mailing of a Redemption Notice
and may (but need not) treat as outstanding any Note authenticated and delivered during such period
in exchange for the not exchanged portion of any Note exchanged in part during such period.

Section 3.03. Payment of Notes Called for Redemption by the Company. If notice of redemption
has been given as provided in Section 3.02, the Notes or portion of Notes with respect to which
such notice has been given shall, unless exchanged into Common Stock pursuant to the terms hereof,
become due and payable on the Redemption Date and at the place or places stated in such notice at
the Redemption Price plus interest accrued to, but not including, the Redemption Date. Interest on
the Notes or portion of Notes so called for redemption shall cease to accrue on and after the
Redemption Date (unless the Company shall default in the payment of the Redemption Price plus
interest accrued to, but not including, the Redemption Date) and after 5:00 p.m., New York City
time, on the second Trading Day immediately preceding the Redemption Date, such Notes shall cease
to be exchangeable into Common Stock and, except as provided in Section 7.05, to be entitled to any
benefit or security under this Indenture, and the holders thereof shall have no right in respect of
such Notes except the right to receive the Redemption Price plus interest accrued to, but not
including, the Redemption Date. On presentation and surrender of such Notes at a place of payment
in said notice specified, the said Notes or the specified portions thereof shall be paid and
redeemed by the Company at the Redemption Price plus interest accrued to, but not including, the
Redemption Date; provided that if the applicable Redemption Date is after the applicable Regular
Record Date and on or before an Interest Payment Date, the Interest payable on such Interest
Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on
the applicable Regular Record Date instead of the holders surrendering such Notes for redemption on
such date.

(a) Upon presentation of any Note redeemed in part only, the Company shall execute and the
Trustee shall authenticate and make available for delivery to the holder thereof, at the expense of
the Company, a new Note or Notes, of authorized denominations, in Principal Amount equal to the
unredeemed portion of the Notes so presented.

Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any Redemption
Notice during the continuance of a default in payment of Interest on the Notes. If any Note called
for redemption shall not be so paid upon surrender thereof for redemption, the principal shall,
until paid or duly provided for, continue to bear interest at the rate borne by the Note,
compounded semi-annually, and such Note shall remain exchangeable into cash or a combination of
cash and Common Stock, as the case may be, until the Principal Amount and Interest shall have been
paid or duly provided for. The Company will notify all of the holders if the Company redeems any
of the Notes.

Section 3.04. Repurchase of Notes by the Company at Option of Holders upon a Fundamental
Change.

(a) If a Fundamental Change shall occur at any time prior to Stated Maturity, each holder
shall have the right, at such holder’s option, to require the Company to repurchase for cash all or
a portion of such holder’s Notes, or any portion of the Principal Amount thereof that is equal to
$1,000 or an integral multiple of $1,000, on the date specified in the Fundamental Change
Repurchase Notice, which date shall be no more than 30 Business Days after the date of the
Fundamental Change Repurchase Notice (subject to extension to comply with applicable law) (the
“Fundamental Change Repurchase Date”). The Company shall repurchase such Notes at a price equal to
100% of the Principal Amount thereof (the “Fundamental Change Repurchase Price”) plus any accrued
and unpaid Interest on the Notes to, but not including, the Fundamental Change Repurchase Date. If
the applicable Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to
the corresponding Interest Payment Date, the Interest payable on such Interest Payment Date shall
be paid on such Interest Payment Date to the holders of record of such Notes on the applicable
record date instead of the holders surrendering such Notes for repurchase on such date.

(b) On or before the 30th calendar day after the occurrence of a Fundamental Change, the
Company, or at its written request the Trustee in the name of and at the expense of the Company
(which request must be received by the Trustee at least five Business Days prior to the date the
Trustee is requested to give notice as described below, unless the Trustee shall agree to a shorter
period), shall mail or cause to be mailed, by first class mail, to all holders of record on such
date a notice (which notice shall be prepared by the Company) (the “Fundamental Change Repurchase
Notice”) of the occurrence of such Fundamental Change and of the repurchase right at the option of
the holders arising as a result thereof to each holder of Notes at its last address as the same
appears on the Note Register, and the Company shall also provide notification thereof in the manner
contemplated by Section 14.01(c) to beneficial owners as required by applicable law; provided that
if the Company shall give such notice, it shall also give written notice of the Fundamental Change
to the Trustee and Paying Agent, if other than the Trustee, at such time as it is mailed to
Noteholders. Such notice, if mailed in the manner herein provided, shall be conclusively presumed
to have been duly given, whether or not the holder receives such notice. Each Fundamental Change
Repurchase Notice shall state, among other things:

(i) the events causing the Fundamental Change;

(ii) the date of the Fundamental Change;

(iii) the last date on which a holder may exercise the repurchase right;

(iv) the Fundamental Change Repurchase Price and, to the extent known at the time of
such notice, the amount of Interest that will be payable with respect to the Notes to, but
not including, the Fundamental Change Repurchase Date;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of the Paying Agent and the Exchange Agent, if the Notes are
then exchangeable in accordance with Section 14.01;

(vii) if the Notes are then exchangeable in accordance with Section 14.01, the
applicable Exchange Rate at the time of such notice (and any applicable adjustments to the
applicable Exchange Rate);

(viii) if the Notes are then exchangeable in accordance with Section 14.01, that Notes
as to which a Fundamental Change Repurchase Election has been given by the holder may be
exchanged only if the election has been withdrawn by the holder in accordance with the terms
of this Indenture;

(ix) that the holder shall have the right to withdraw any Notes surrendered prior to
5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental
Change Repurchase Date (or any such later time as may be required by applicable law);

(x) a description of the procedures which a Noteholder must follow to exercise such
repurchase right or to withdraw any surrendered Notes;

(xi) the CUSIP, ISIN or similar number or numbers of the Notes (if then generally in
use); and

(xii) briefly, the exchange rights of the holders of the Notes.

No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 3.04.

(c) Notes shall be repurchased pursuant to this Section 3.04 at the option of the holder upon:

(i) delivery to the Paying Agent by a holder of a duly completed notice (a “Fundamental
Change Repurchase Election”) in the form set forth on the reverse of the Note at any time
prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the
Fundamental Change Repurchase Date, which is subject to extension to comply with applicable
law, stating:

(A) if certificated notes have been issued, the certificate numbers of the
Notes which the holder shall deliver to be repurchased;

(B) the portion of the Principal Amount of the Notes that the holder shall
deliver to be repurchased, which portion must be $1,000 or an integral multiple
thereof; and

(C) that such Notes shall be repurchased by the Company as of the Fundamental
Change Repurchase Date pursuant to the terms and conditions specified in the Notes
and in the Indenture; and

(ii) delivery or book-entry transfer of the Notes to the Paying Agent simultaneously
with or at any time after delivery of the Fundamental Change Repurchase Election (together
with all necessary endorsements) at the Corporate Trust Office of the Paying Agent, such
delivery or transfer being a condition to receipt by the holder of the Fundamental Change
Repurchase Price therefor; provided that such Fundamental Change Repurchase Price shall be
so paid pursuant to this Section 3.04 only if the Notes so delivered or transferred to the
Paying Agent shall conform in all respects to the description thereof in the related
Fundamental Change Repurchase Election. All questions as to the validity, eligibility

If the Notes are not in certificated form, holders must provide notice of their election in
accordance with the appropriate procedures of the Depositary.

Section 3.05. Repurchase of Notes by the Company at Option of Holders on Specified Dates.

(a) On each of December 15, 2010, December 15, 2015 and December 15, 2020 (each, a “Company
Repurchase Date”), each holder shall have the right, at such holder’s option, to require the
Company to repurchase for cash all of such holder’s Notes, or any portion of the Principal Amount
thereof that is an integral multiple of $1,000. The Company shall repurchase such Notes at a price
equal to 100% of the Principal Amount thereof (the “Company Repurchase Price”) plus any accrued and

be payable to the holder of record on the corresponding Regular Record Date.

(b) On or before the 20th Business Day prior to each Company Repurchase Date, the Company, or
at its written request the Trustee in the name of and at the expense of the Company (which request
must be received by the Trustee at least five Business Days prior to the date the Trustee is
requested to give notice as described below, unless the Trustee shall agree to a shorter period),
shall mail or cause to be mailed, by first class mail, to all holders of record on such date a
notice (which notice shall be prepared by the Company) of such optional repurchase (the “Company
Repurchase Notice”) to each holder of Notes at its last address as the same appears on the Note
Register, and the Company shall also provide notification thereof in the manner contemplated by
Section 14.01(c) to beneficial owners as required by applicable law; provided that if the Company
shall give such notice, it shall also give written notice to the Trustee and Paying Agent, if other
than the Trustee, at such time as it is mailed to Noteholders. Such notice, if mailed in the
manner herein provided, shall be conclusively presumed to have been duly given, whether or not the
holder receives such notice. Each Company Repurchase Notice shall state, among other things:

(i) the last date on which a holder may exercise the repurchase right;

(ii) the Company Repurchase Price and, to the extent known at the time of such notice,
the amount of Interest that will be payable with respect to the Notes to, but not including,
the Company Repurchase Date;

(iii) the Company Repurchase Date;

(iv) the name and address of the Paying Agent and the Exchange Agent, if the Notes are
then exchangeable in accordance with Section 13.01;

(v) if the Notes are then exchangeable in accordance with Section 13.01, the applicable
Exchange Rate at the time of such notice (and any applicable adjustments to the applicable
Exchange Rate);

(vi) if the Notes are then exchangeable in accordance with Section 13.01, those Notes
as to which a Company Repurchase Election has been given by the holder may be exchanged only
if the election has been withdrawn by the holder in accordance with the terms of this
Indenture;

(vii) that the holder shall have the right to withdraw any Notes surrendered prior to
5:00 p.m., New York City time, on the Business Day immediately preceding the Company
Repurchase Date (or any such later time as may be required by applicable law);

(viii) a description of the procedures which a Noteholder must follow to exercise such
repurchase right or to withdraw any surrendered Notes;

(ix) the CUSIP, ISIN or similar number or numbers of the Notes (if then generally in
use); and

(x) briefly, the exchange rights of the holders of the Notes.

No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 3.05.

(c) Notes shall be repurchased pursuant to this Section 3.05 at the option of the holder upon:

(i) delivery to the Paying Agent by a holder of a duly completed notice (a “Company
Repurchase Election”) in the form set forth on the reverse of the Note at any time from 9:00
a.m., New York City time, on the 20th Business Day preceding the Company
Repurchase Date until 5:00 p.m., New York City time, on the Business Day immediately
preceding the Company Repurchase Date, stating:

(A) if certificated Notes have been issued, the certificate numbers of the
Notes which the holder shall deliver to be repurchased;

the Indenture; and

(ii) delivery or book-entry transfer of the Notes to the Paying Agent simultaneously
with or at any time after delivery of the Company Repurchase Election (together with all
necessary endorsements) at the Corporate Trust Office of the Paying Agent, such delivery or
transfer being a condition to receipt by the holder of the Company Repurchase Price
therefor; provided that such Company Repurchase Price shall be so paid pursuant to this
Section 3.05 only if the Notes so delivered or transferred to the Paying Agent shall conform
in all respects to the description thereof in the related Company Repurchase Election. All
questions as to the validity, eligibility (including time of receipt) and acceptance of any
Note for repurchase shall be determined by the Company, whose determination shall be final
and binding absent manifest error.

If the Notes are not in certificated form, holders must provide notice of their election in
accordance with the appropriate procedures of the Depositary.

Section 3.06. Conditions and Procedures for Repurchase at Option of Holders.

(a) At the request of the holder, the Company shall repurchase from such holder, pursuant to
Section 3.04 or Section 3.05, a portion of a Note, if the Principal Amount of such portion is
$1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of
all of a Note also apply to the repurchase of such portion of such Note. Upon presentation of any
Note repurchased in part only, the Company shall execute and the Trustee shall authenticate and
make available for delivery to the holder thereof, at the expense of the Company, a new Note or
Notes, of any authorized denomination, in aggregate Principal Amount equal to the portion of the
Notes presented not repurchased.

(b) On or prior to a Repurchase Date, the Company will deposit with the Paying Agent (or, if
the Company or the Issuer is acting as the Paying Agent, set aside, segregate and hold in trust as
provided in Section 4.04) an amount of money sufficient to repurchase on the Repurchase Date all
the Notes or portions thereof to be repurchased on such date at the Repurchase Price plus accrued
and unpaid Interest, if any, to, but not including, the Repurchase Date, if applicable; provided
that if such deposit is made on the Repurchase Date it must be received by the Trustee or Paying
Agent, as the case may be, by 10:00 a.m., New York City time, on such date.

If on the Repurchase Date the Trustee or other Paying Agent appointed by the Company (or, if
the Company or the Issuer is acting as the Paying Agent, the Company or the Issuer) holds money
sufficient to pay the aggregate Repurchase Price of all the Notes or portions thereof that are to
be repurchased plus accrued and unpaid Interest, if any, to, but not including, the Repurchase
Date, if applicable, then, on such Repurchase Date (i) such Notes will cease to be outstanding,
(ii) Interest on such Notes will cease to accrue (in the case of clauses (i) and (ii), whether or
not book-entry transfer of the Notes has been made or the Notes have been delivered to the Paying
Agent, as the case may be), and (iii) all other rights of the holders of such Notes will terminate
(other than the right to receive the Repurchase Price plus accrued and unpaid Interest, if any, to,
but not including, the Repurchase Date, if applicable upon book-entry transfer or delivery of the
Notes, as the case may be).

(c) Upon receipt by the Paying Agent of a Repurchase Election, the holder of the Note in
respect of which such Repurchase Election was given shall (unless such Repurchase Election is
validly withdrawn) thereafter be entitled to receive solely the Repurchase Price with respect to
such Note plus accrued and unpaid Interest, if any, to, but not including, the Repurchase Date, if
applicable. Such Repurchase Price plus accrued and unpaid Interest, if any, to, but not including,
the Repurchase Date, if applicable, shall be paid to such holder, subject to receipt of funds
and/or Notes by the Paying Agent, promptly following the later of (x) the Repurchase Date with
respect to such Note (provided the holder has satisfied the conditions in Section 3.04(c) or
Section 3.05(c), as applicable) and (y) the time of book-entry transfer or delivery of such Note to
the Paying Agent by the holder thereof in the manner required by Section 3.04(c) or Section
3.05(c), as applicable. Notes in respect of which a Repurchase Election has been given by the
holder thereof may not be exchanged pursuant to Article 14 hereof on or after the date of the
delivery of such Repurchase Election unless such Repurchase Election has first been validly
withdrawn.

(d) Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent
a Repurchase Election shall have the right to withdraw such Repurchase Election, in whole or in
part, at any time prior to 5:00 p.m., New York City time, on the Business Day preceding the
Repurchase Date (or any such later time as may be required by applicable law) by delivery of a
written notice of withdrawal to the Paying Agent, specifying:

(i) if certificated Notes have been issued, the certificate numbers of the withdrawn
Notes;

(ii) the Principal Amount of the Note with respect to which such notice of withdrawal
is being submitted; and

(iii) the Principal Amount, if any, of such Note which remains subject to the original
Repurchase Election and which has been or will be delivered for repurchase by the Company.

If the Notes are not in certificated form, holders must provide notice of their withdrawal in
accordance with the appropriate procedures of the Depositary.

The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase
Election or written notice of withdrawal thereof.

(e) The Company will comply with the provisions of Rule 13e-4 and any other tender offer rules
under the Exchange Act to the extent then applicable in connection with the repurchase rights of
the holders of Notes in the event of a Fundamental Change or on any Company Repurchase Date. If
then required by applicable rules, the Company will file a Schedule TO or any other schedule
required in connection with any offer by the Company to repurchase Notes.

(f) There shall be no repurchase of any Notes pursuant to Section 3.04 or Section 3.05 if
there has occurred at any time prior to, and is continuing on, the Repurchase Date an Event of
Default (other than an Event of Default that is cured by the payment of the Repurchase Price with
respect to such Notes). The Paying Agent will promptly return to the respective holders thereof
any Notes (x) with respect to which a Repurchase Election has been withdrawn in compliance with
this Indenture or (y) held by it during the continuance of an Event of Default (other than a
default in the payment of the Repurchase Price with respect to such Notes) in which case, upon such
return, the Repurchase Election with respect thereto shall be deemed to have been withdrawn.

(g) The Paying Agent shall return to the Company any cash that remains unclaimed as provided
in Section 11.03, together with interest, if any, thereon, held by them for the payment of the
Repurchase Price; provided that to the extent that the aggregate amount of cash deposited by the
Company pursuant to Section 3.06(b) exceeds the aggregate Repurchase Price of the Notes or portions
thereof which the Company is obligated to purchase as of the Repurchase Date then, unless otherwise
agreed in writing with the Company, promptly after the Business Day following the Repurchase Date,
the Paying Agent shall return any such excess to the Company together with interest, if any,
thereon.

(h) In the case of (i) a reclassification, change, consolidation, merger, binding share
exchange, combination, sale or conveyance to which Section 14.06 applies, in which the Common Stock
of the Issuer is changed or exchanged as a result into the right to receive cash, securities or
other property, which includes shares of Common Stock of the Issuer or shares of common stock of
another Person that are, or upon issuance will be, traded on a United States national securities
exchange or approved for trading on an established automated over-the-counter trading market in the
United States and such shares constitute at the time such change or exchange becomes effective in
excess of 50% of the aggregate fair market value of such cash, securities or other property (as
determined by the Company, which determination shall be conclusive and binding) or (ii) a Public
Acquirer Change of Control in which the Company has made the election pursuant to Section 14.07 to
adjust the Exchange Rate and related exchange obligation, then the Company shall execute and
deliver to the Trustee a supplemental indenture (accompanied by an Opinion of Counsel that such
supplemental indenture complies with the Trust Indenture Act as in force at the date of execution
of such supplemental indenture and is authorized or permitted by this Indenture) modifying the
applicable provisions of this Article 3 and the definition of Fundamental Change, as appropriate,
as determined in good faith by the Company (which determination shall be conclusive and binding),
to make such provisions apply to such other Person if different from the Issuer (in lieu of the
Issuer).

time to time rescind such designations. The Company will give prompt written notice of any such
designation or rescission and of any change in the location of any such other office or agency.

The Company hereby initially designates the Trustee as Paying Agent, Note Registrar, Custodian
and Exchange Agent, and each of the Corporate Trust Office and the office of agency of the Trustee
and its affiliate located at 101 Barclay Street, 8W, New York, New York 10286 shall be considered

mailed, the notices set forth in Section 7.10(a) and the third paragraph of Section 7.11. If
co-registrars have been appointed in accordance with this Section, the Trustee shall mail such
notices only to the Company and the holders of Notes it can identify from its records.

Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided
in Section 7.10, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent
other than the Trustee, or if the Trustee shall appoint such a Paying Agent, the Company will cause
such Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section 4.04:

(1) that it will hold all sums held by it as such agent for the payment of the
Principal Amount of or Interest on the Notes (whether such sums have been paid to it by the
Company or by any other obligor on the Notes) in trust for the benefit of the holders of the
Notes;

(2) that it will give the Trustee notice of any failure by the Company (or by any other
obligor on the Notes) to make any payment of the Principal Amount of or Interest on the
Notes when the same shall be due and payable; and

(3) that at any time during the continuance of an Event of Default, upon request of the
Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Company shall, on or before each due date of the Principal Amount of or Interest on the
Notes, deposit with the Paying Agent a sum (in funds which are immediately available on the due
date for such payment) sufficient to pay such Principal Amount or Interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such
action; provided that if such deposit is made on the due date, such deposit shall be received by
the Paying Agent by 10:00 a.m., New York City time, on such date.

(b) If the Company or the Issuer shall act as Paying Agent, it will, on or before each due
date of the Principal Amount of or Interest on the Notes, set aside, segregate and hold in trust
for the benefit of the holders of the Notes a sum sufficient to pay such Principal Amount or
Interest so becoming due and will promptly notify the Trustee of any failure to take such action
and of any failure by the Company (or any other obligor under the Notes) to make any payment of the
Principal Amount of or Interest on the Notes when the same shall become due and payable.

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust by the Company, the Issuer or
any Paying Agent hereunder as required by this Section 4.04, such sums to be held by the Trustee
upon the trusts herein contained and upon such payment by the Company, the Issuer or any Paying
Agent to the Trustee, the Company, the Issuer or such Paying Agent shall be released from all
further liability with respect to such sums.

(d) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums

Company or the Issuer if acting as Paying Agent) and shall have no control of any funds held by
such other Paying Agents.

Section 4.05. Existence. Subject to Article 11, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence and rights (charter
and statutory); provided that the Company shall not be required to preserve any such right if the
Company shall determine that the preservation thereof is no longer desirable in the conduct of the
business of the Company and that the loss thereof is not disadvantageous in any material respect to
the Noteholders.

Section 4.06. Rule 144A Information Requirement. Within the period prior to the expiration of
the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any

13 or 15(d) under the Exchange Act, make available to any holder or beneficial holder of Notes or
any Common Stock issued upon exchange thereof which continue to be Restricted Securities in
connection with any sale thereof and any prospective purchaser of Notes or such Common Stock
designated by such holder or beneficial holder, the information required pursuant to Rule
144A(d)(4) under the Securities Act upon the request of any holder or beneficial holder of the
Notes or such Common Stock and it will take such further action as any holder or beneficial holder
of such Notes or such Common Stock may reasonably request, all to the extent required from time to
time to enable such holder or beneficial holder to sell its Notes or Common Stock without
registration under the Securities Act within the limitation of the exemption provided by Rule 144A,
as such Rule may be amended from time to time. Upon the request of any holder or any beneficial
holder of the Notes or such Common Stock, the Company and the Issuer will deliver to such holder a
written statement as to whether it has complied with such requirements.

Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law or other law which
would prohibit or forgive the Company from paying all or any portion of the Principal Amount of or
Interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in
force, or which may affect the covenants or the performance of this Indenture and the Company (to
the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law,
and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

Section 4.08. Compliance Certificate. The Company shall deliver to the Trustee, within one
hundred twenty calendar days after the end of each fiscal year of the Company (which fiscal year of
the Company presently ends on the Sunday nearest to January 31), a certificate signed by either the
principal executive officer, principal financial officer or principal accounting officer of the
Company, stating whether or not to the best knowledge of the signer thereof the Company or the
Issuer is in default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Company or the Issuer shall be in default, specifying all such
defaults and the nature and the status thereof of which the signer may have knowledge.

The Company will deliver to the Trustee, promptly upon becoming aware of (i) any default in
the performance or observance of any covenant, agreement or condition contained in this Indenture,
or (ii) any Event of Default, an Officers’ Certificate specifying with particularity such default
or Event of Default and further stating what action the Company or the Issuer has taken, is taking
or proposes to take with respect thereto.

Any notice required to be given under this Section 4.08 shall be delivered to a Responsible
Officer of the Trustee at its Corporate Trust Office.

Section 4.09. Additional Interest Notice. In the event that the Company is required to pay
Additional Interest to holders of Notes pursuant to the Registration Rights Agreement, the Company
will provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay
Additional Interest no later than fifteen calendar days prior to the proposed payment date for the
Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional
Interest to be paid by the Company on such payment date. The Trustee shall not at any time be
under any duty or responsibility to any holder of Notes to determine the Additional Interest, or
with respect to the nature, extent or calculation of the amount of Additional Interest when made,
or with respect to the method employed in such calculation of the Additional Interest.

Section 4.10. Future Guarantors. The Company shall cause each Person that becomes a Domestic
Subsidiary to execute and deliver to the Trustee promptly after such Person becomes a Domestic

Trustee may request in writing, within 30 calendar days after receipt by the Company of any such

Section 5.02. Preservation and Disclosure of Lists. (a) The Trustee shall preserve, in as
current a form as is reasonably practicable, all information as to the names and addresses of the
holders of Notes contained in the most recent list furnished to it as provided in Section 5.01 or

upon receipt of a new list so furnished.

(b) The rights of Noteholders to communicate with other holders of Notes with respect to their
rights under this Indenture or under the Notes, and the corresponding rights and duties of the
Trustee, shall be as provided by the Trust Indenture Act.

(c) Every Noteholder, by receiving and holding the same, agrees with the Company and the
Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held
accountable by reason of any disclosure of information as to names and addresses of holders of
Notes made pursuant to the Trust Indenture Act.

Section 5.03. Reports by Trustee. (a) Within 60 calendar days after February 1 of each year

when the Notes are listed on any stock exchange or automated quotation system or delisted
therefrom.

Section 5.04. Reports by Company. The Company shall file with the Trustee (and the Commission
if at any time after the Indenture becomes qualified under the Trust Indenture Act), and transmit
to holders of Notes, such information, documents and other reports and such summaries thereof, as

fifteen calendar days after the same is so required to be filed with the Commission. Delivery of
such reports, information and documents to the Trustee is for informational purposes only and the

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

or other proceeding seeking liquidation, reorganization or other relief with respect to the
Company, the Issuer or any Significant Subsidiary or its debts under any bankruptcy, insolvency or
other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of the Company, the Issuer or any Significant
Subsidiary or any substantial part of the property of the Company, the Issuer or any Significant
Subsidiary, or consent by the Company, the Issuer or any Significant Subsidiary to any such relief
or to the appointment of or taking possession by any such official in an involuntary case or other
proceeding commenced against the Company, the Issuer or any Significant Subsidiary, or general
assignment by the Company, the Issuer or any Significant Subsidiary for the benefit of creditors,
or failure of the Company, the Issuer or any Significant Subsidiary generally to pay its debts as
they become due; or

(k) commencement of an involuntary case or other proceeding against the Company, the Issuer or
any Significant Subsidiary seeking liquidation, reorganization or other relief with respect to the
Company, the Issuer or any Significant Subsidiary or its debts under any bankruptcy, insolvency or
other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver,
liquidator, custodian or other similar official of the Company, the Issuer or any Significant
Subsidiary or any substantial part of the property of the Company, the Issuer or any Significant
Subsidiary, and such involuntary case or other proceeding shall remain undismissed and unstayed for
a period of 60 calendar consecutive days;

then, and in each and every such case (other than an Event of Default specified in Section 6.01(j)
or Section 6.01(k)), unless the Principal Amount of all of the Notes shall have already become due
and payable, either the Trustee or the holders of not less than 25% in aggregate Principal Amount
of the Notes then outstanding hereunder determined in accordance with Section 8.04, by notice in
writing to the Company (and to the Trustee if given by Noteholders), may declare the Principal
Amount of all the Notes and the Interest accrued and unpaid thereon to be due and payable
immediately, and upon any such declaration the same shall become and shall be immediately due and
payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If
an Event of Default specified in Section 6.01(h) or Section 6.01(k) occurs, the Principal Amount of
all the Notes and the Interest accrued and unpaid thereon shall be immediately and automatically
due and payable without necessity of further action. If, however, at any time after the Principal
Amount of the Notes shall have been so declared due and payable, and before any judgment or decree
for the payment of the monies due shall have been obtained or entered as hereinafter provided, (a)
the Company shall pay or shall deposit with the Trustee a sum sufficient to pay (i) all matured
installments of Interest upon all Notes, (ii) the Principal Amount of any and all Notes which shall
have become due otherwise than by acceleration, (iii) interest on overdue installments of Interest
(to the extent that payment of such interest is enforceable under applicable law) and on such
Principal Amount at the rate borne by the Notes, to the date of such payment or deposit and (iv)
amounts due to the Trustee pursuant to Section 7.06, and (b) any and all defaults under this
Indenture, other than the nonpayment of Principal Amount of and accrued and unpaid Interest on
Notes which shall have become due by acceleration, shall have been cured or waived pursuant to ,
then and in every such case the holders of a majority in aggregate Principal Amount of the Notes
then outstanding on behalf of the holders of all of the Notes then outstanding, by written notice
to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and
annul such declaration and its consequences subject to Section 6.07; but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default or Event of
Default, or shall impair any right consequent thereon. The Company shall notify in writing a
Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default,
as provided in Section 4.08.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such waiver or rescission and
annulment or for any other reason or shall have been determined adversely to the Trustee, then and
in every such case the Company, the holders of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights, remedies and powers
of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding
had been taken.

Section 6.02. Payments of Notes on Default; Suit Therefor. The Company covenants that in the
case of an Event of Default pursuant to Section 6.01(a) or Section 7.01(b), then, upon demand of
the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, (i)
the whole amount that then shall have become due and payable on all such Notes for Principal Amount
or Interest, as the case may be, with interest upon the overdue Principal Amount and (to the extent
that payment of such interest is enforceable under applicable law) upon the overdue installments of
Interest at the rate borne by the Notes, from the required payment date, and (ii) in addition
thereto, any amounts due the Trustee under Section 7.06. Until such demand by the Trustee, the
Company may pay the Principal Amount of and Interest on the Notes to the registered holders,
whether or not the Notes are overdue.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in
its own name and as trustee of an express trust, shall be entitled and empowered to institute any
actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and
may prosecute any such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes and collect in the
manner provided by law out of the property of the Company or any other obligor on the Notes
wherever situated the monies adjudged or decreed to be payable.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the
Company, the Issuer or any Significant Subsidiary or any other obligor on the Notes under Title 11
of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee
in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Company, the Issuer or any Significant Subsidiary or such
other obligor, the property of the Company, the Issuer or any Significant Subsidiary or such other
obligor, or in the case of any other judicial proceedings relative to the Company, the Issuer or
any Significant Subsidiary or such other obligor upon the Notes, or to the creditors or property of
the Company, the Issuer or any Significant Subsidiary or such other obligor, the Trustee,
irrespective of whether the Principal Amount of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole
amount of the Principal Amount and Interest owing and unpaid in respect of the Notes, and, in case
of any judicial proceedings, 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 and of the Noteholders allowed in
such judicial proceedings relative to the Company or any other obligor on the Notes, its or their
creditors, or its or their property, and to collect and receive any monies or other property
payable or deliverable on any such claims, and to distribute the same after the deduction of any
amounts due the Trustee under Section 7.06, and to take any other action with respect to such
claims, including participating as a member of any official committee of creditors, as it
reasonably deems necessary or advisable, and, unless prohibited by law or applicable regulations,
and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or
similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses,
advances and disbursements, including counsel fees and expenses incurred by it up to the date of
such distribution. To the extent that such payment of reasonable compensation, expenses, advances
and disbursements out of the estate in any such proceedings 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, monies, securities and other property which the holders of the Notes may be entitled to
receive in such proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

All rights of action and of asserting claims under this Indenture, or under any of the Notes,
may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation
of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held
to represent all the holders of the Notes, and it shall not be necessary to make any holders of the
Notes parties to any such proceedings.

Section 6.03. Application of Monies Collected by Trustee. Any monies or other property
collected by the Trustee pursuant to this Article 6, or any monies or other property otherwise
distributable in respect of the Company’s obligations under this Indenture, shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution of such monies,
upon presentation of the several Notes, and stamping thereon the payment, if only partially paid,
and upon surrender thereof, if fully paid:

FIRST: To the payment of all amounts due the Trustee (including any predecessor Trustee) under
Section 7.06;

SECOND: In case the Principal Amount of the outstanding Notes shall not have become due and be
unpaid, to the payment of Interest on the Notes in default in the order of the maturity of the
installments of such Interest, with interest (to the extent that such interest has been collected
by the Trustee) as provided in Section 6.02 upon the overdue installments of Interest at the rate
borne by the Notes, such payments to be made ratably to the Persons entitled thereto;

THIRD: In case the Principal Amount of the outstanding Notes shall have become due, by
declaration or otherwise, and be unpaid, to the payment of the whole amount then owing and unpaid
upon the Notes for Principal Amount and Interest, with interest on the overdue Principal Amount and
(to the extent that such interest has been collected by the Trustee) upon overdue installments of
Interest, at the rate borne by the Notes, and in case such monies shall be insufficient to pay in
full the whole amounts so due and unpaid upon the Notes, then to the payment of such Principal
Amount and Interest without preference or priority of the Principal Amount over Interest, or of
Interest over the Principal Amount, or of any installment of Interest over any other installment of
Interest, or of any Note over any other Note, ratably to the aggregate of such Principal Amount and
accrued and unpaid Interest; and

FOURTH: To the payment of the remainder, if any, to the Company or any other Person lawfully
entitled thereto, as determined by a court of competent jurisdiction.

Section 6.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue
of or by reference to any provision of this Indenture to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any other remedy
hereunder, unless (a) such holder previously shall have given to the Trustee written notice of an
Event of Default and of the continuance thereof, as hereinbefore provided, (b) the holders of not
less than 25% in aggregate Principal Amount of the Notes then outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such security or indemnity satisfactory to the
Trustee as it may require against the costs, expenses and liabilities to be incurred therein or
thereby, (c) the Trustee for 60 calendar days after its receipt of such notice, request and offer
of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and
(d) no direction inconsistent with such written request shall have been given to the Trustee
pursuant to Section 6.07; it being understood and intended, and being expressly covenanted by the
taker and holder of every Note with every other taker and holder and the Trustee, that no one or
more holders of Notes shall have any right in any manner whatever by virtue of or by reference to
any provision of this Indenture to affect, disturb or prejudice the rights of any other holder of
Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to
enforce any right under this Indenture, except in the manner herein provided and for the equal,
ratable and common benefit of all holders of Notes (except as otherwise provided herein). For the
protection and enforcement of this Section 6.04, each and every Noteholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any holder of any Note to receive payment of the Principal Amount of (including any Redemption
Price or Repurchase Price pursuant to Article 3) and accrued Interest on such Note on or after the
respective due dates expressed in such Note, or to institute suit for the enforcement of any such
payment on or after such respective dates against the Company, shall not be impaired or affected
without the consent of such holder.

Anything contained in this Indenture or the Notes to the contrary notwithstanding, the holder
of any Note, without the consent of either the Trustee or the holder of any other Note, in its own
behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable
to enforce, its rights of exchange as provided herein.

Section 6.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its
discretion, proceed to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either
by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

Section 6.06. Remedies Cumulative and Continuing. Except as provided in Section 2.06, all
powers and remedies given by this Article 6 to the Trustee or to the Noteholders shall, to the
extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other
powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings
or otherwise, to enforce the performance or observance of the covenants and agreements contained in
this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to
exercise any right or power accruing upon any default or Event of Default occurring and continuing
as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such
default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power
and remedy given by this Article 6 or by law to the Trustee or to the Noteholders may be exercised
from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The
holders of a majority in aggregate Principal Amount of the Notes at the time outstanding determined
in accordance with Section 8.04 shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee; provided that (a) such direction shall not be in conflict with any rule
of law or with this Indenture, (b) the Trustee may take any other action which is not inconsistent
with such direction, (c) the Trustee may decline to take any action that would benefit some
Noteholders to the detriment of other Noteholders and (d) the Trustee may decline to take any
action that would involve the Trustee in personal liability. The holders of a majority in
aggregate Principal Amount of the Notes at the time outstanding determined in accordance with
Section 8.04 may, on behalf of the holders of all of the Notes, waive any past default or Event of
Default hereunder and its consequences except (i) a default in the payment of Interest on, or the
Principal Amount of, the Notes, (ii) a failure by the Company to exchange any Notes into cash or a
combination of cash and Common Stock, as the case may be, (iii) a default in the payment of the
Redemption Price pursuant to Section 3.03, (iv) a default in the payment of the Fundamental Change
Repurchase Price pursuant to Section 3.04 or Company Repurchase Price pursuant to Section 3.05 or
(v) a default in respect of a covenant or provision hereof which under Article 10 cannot be
modified or amended without the consent of the holders of each or all Notes then outstanding or
affected thereby. Upon any such waiver, the Company, the Trustee and the holders of the Notes
shall be restored to their former positions and rights hereunder; but no such waiver shall extend
to any subsequent or other default or Event of Default or impair any right consequent thereon.
Whenever any default or Event of Default hereunder shall have been waived as permitted by this
Section 6.07, said default or Event of Default shall for all purposes of the Notes and this
Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to
any subsequent or other default or Event of Default or impair any right consequent thereon.

Section 6.08. Notice of Defaults. The Trustee shall, within ninety calendar days after a
Responsible Officer of the Trustee has actual knowledge of the occurrence of a default, mail to all
Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of
all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived
before the giving of such notice; provided that except in the case of default in the payment of the
Principal Amount of or Interest on any of the Notes, the Trustee shall be protected in withholding
such notice if and so long as a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the interests of the
Noteholders. For the purpose of this Section 6.08, the term “default” means any event which is, or
after notice or lapse of time or both would become, an Event of Default.

Section 6.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder
of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its
discretion, require, in any suit for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by
any party litigant in such suit of an undertaking to pay the costs of such suit and that such court
may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; provided that the provisions of this Section 6.09
(to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten
percent in Principal Amount of the Notes at the time outstanding determined in accordance with
Section 8.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the
Principal Amount of or Interest on any Note on or after the due date expressed in such Note or to
any suit for the enforcement of the right to exchange any Note in accordance with the provisions of
Article 14.

ARTICLE 7

The Trustee

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of
an Event of Default and after the curing of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under
the circumstances in the conduct of such person’s own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from liability for
its own negligent action, its own negligent failure to act or its own willful misconduct, except
that:

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all
Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express
provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be
liable except for the performance of such duties and obligations as are specifically set
forth in this Indenture and no implied covenants or obligations shall be read into this
Indenture and the Trust Indenture Act against the Trustee; and

(ii) in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely as to the truth of the statements and the correctness of the opinions
expressed therein, upon any certificates or opinions furnished to the Trustee and conforming
to the requirements of this Indenture; but, in the case of any such certificates or opinions
which by any provisions hereof are specifically required to be furnished to the Trustee, the
Trustee shall be under a duty to examine the same to determine whether or not they conform
to the requirements of this Indenture (but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein);

(b) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining
the pertinent facts;

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by
it in good faith in accordance with the written direction of the holders of not less than a
majority in Principal Amount of the Notes at the time outstanding determined as provided in Section
8.04 relating to the time, method and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

(d) the Trustee shall not be liable in respect of any payment (as to the correctness of
amount, entitlement to receive or any other matters relating to payment) or notice effected by the
Company, the Issuer or any Paying Agent or any records maintained by any co-registrar with respect
to the Notes; and

(e) if any party fails to deliver a notice relating to an event the fact of which, pursuant to
this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its
failure to receive such notice as reason to act as if no such event occurred.

(f) The Trustee shall not be deemed to have knowledge or notice of any default (as defined in
Section 6.08) or Event of Default hereunder unless a Responsible Officer of the Trustee shall have
received at the Corporate Trust Office written notice of such default or Event of Default from the
Company or the holders of at least 10% in aggregate Principal Amount of the Notes and such notice
refers to such default or Event of Default, the Notes and the Indenture.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur any liability in the performance of any of its duties or in the
exercise of any of its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is not assured to it.

Whether or not therein provided, every provision of this Indenture relating to the conduct or
affecting the liability of, or affording protection to, the Trustee shall be subject to the
provisions of this Section 7.01.

Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section
7.01:

(a) the Trustee may conclusively rely and shall be protected in acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, note,
coupon or other paper or document (whether in its original or facsimile form) believed by it in
good faith to be genuine and to have been signed or presented by the proper party or parties;

(b) any request, direction, order or demand of the Company, the Issuer or any Subsidiary
Guarantor mentioned herein shall be sufficiently evidenced by an Officers’ Certificate (unless
other evidence in respect thereof be herein specifically prescribed); and any resolution of the
Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or
an Assistant Secretary of the Company;

Counsel shall be full and complete authorization and protection in respect of any action taken or
omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the
provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or
indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred
therein or thereby;

(e) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, note or other paper or document, but the Trustee may make such further
inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the books,
records and premises of the Company, the Issuer and any Subsidiary Guarantor, personally or by
agent or attorney at the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation;

(f) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed by it
with due care hereunder;

(g) the Trustee shall not be liable for any action taken, suffered or omitted to be taken by
it in good faith and reasonably believed by it to be authorized or within the discretion or rights
or powers conferred upon it by this Indenture;

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

(i) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder;

(j) the Trustee may request that the Company, the Issuer and any Subsidiary Guarantor,
respectively deliver an Officers’ Certificate setting forth the names of individuals and/or titles
of officers authorized at such time to take specified actions pursuant to this Indenture, which
Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate,
including any person specified as so authorized in any such certificate previously delivered and
not superseded;

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

(l) the Trustee may consult with counsel of its selection and the advice of such counsel or
any Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; and

(m) the Trustee agrees to accept and act upon facsimile transmission of written instructions
or directions pursuant to this Indenture, it being understood that originals of such shall be
provided to the Trustee in a timely manner.

Section 7.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the
Notes (except in the Trustee’s certificate of authentication) and the Guarantees shall be taken as
the statements of the Company, the Issuer and the Subsidiary Guarantors, respectively, and the
Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee
shall not be accountable for the use or application by the Company of any Notes or the proceeds of
any Notes authenticated and delivered by the Trustee in conformity with the provisions of this
Indenture.

Section 7.04. Trustee, Paying Agents, Exchange Agents or Registrar May Own Notes. The
Trustee, any Paying Agent, any Exchange Agent or Note Registrar, in its individual or any other
capacity, may become the owner or pledgee of Notes with the same rights it would have if it were

monies received by the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received. Money held by the Trustee in trust hereunder need
not be segregated from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as may be agreed in
writing from time to time by the Company and the Trustee.

Section 7.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay
to the Trustee from time to time, and the Trustee shall receive, such compensation for all services
rendered by it hereunder in any capacity (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust) as mutually agreed to from time to
time in writing between the Company and the Trustee, and the Company will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made
by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable
compensation and the expenses and disbursements of its counsel and of all Persons not regularly in
its employ) except any such expense, disbursement or advance as may arise from its negligence,
willful misconduct or bad faith. The Company, the Issuer and the Subsidiary Guarantors, jointly
and severally, also covenant to indemnify the Trustee and any predecessor Trustee (or any officer,
director or employee of the Trustee), in any capacity under this Indenture and its agents and any
authenticating agent for, and to hold them harmless against, any and all loss, liability, damage,
claim or expense including taxes (other than taxes based on the income of the Trustee) incurred
without negligence, willful misconduct or bad faith on the part of the Trustee or such officers,
directors, employees and agent or authenticating agent, as the case may be, and arising out of or
in connection with the acceptance or administration of this trust or in any other capacity
hereunder, including the costs and expenses (including reasonable attorneys’ fees and expenses) of
defending themselves against any claim (whether asserted by the Company, the Issuer, the Subsidiary
Guarantors, any holder or any other Person) of liability in connection with the exercise or
performance of any of its powers or duties hereunder. The respective obligations of the Company,
the Issuer and the Subsidiary Guarantors under this Section 7.06 to compensate or indemnify the
Trustee and to pay or reimburse the Trustee for expenses (including reasonable attorneys’ fees and
expenses), disbursements and advances shall be secured by a lien prior to that of the Notes upon
all property and funds held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Notes. The obligation of the Company, the Issuer and the
Subsidiary Guarantors under this Section shall survive the resignation or removal of the Trustee
and the satisfaction and discharge or termination of this Indenture.

When the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(h) or Section 6.01(k) with respect to the
Company occurs, the expenses (including reasonable attorneys’ fees and expenses) and the
compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws.

Section 7.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section
7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or omitting any
action hereunder, such matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of bad faith or willful misconduct on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers’ Certificate delivered to the
Trustee.

Section 7.08. Conflicting Interests of Trustee. If the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture.

Section 7.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which
shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank
holding company system, its bank holding company shall have a combined capital and surplus of at
least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.10. Resignation or Removal of Trustee.

(a) The Trustee may at any time resign by giving written notice of such resignation to the
Company and to the holders of Notes. Upon receiving such notice of resignation, the Company shall
promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the
Company’s Board of Directors, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment 60 calendar days after the mailing of such notice of
resignation to the Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the
Company and the Noteholders, petition, at the expense of the Company, any court of competent
jurisdiction for the appointment of a successor trustee, or, if any Noteholder who has been a bona
fide holder of a Note or Notes for at least six months may, subject to the provisions of Section
6.09, on behalf of himself and all others similarly situated, petition any such court for the
appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may
deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with Section 7.08 after written request therefor
by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for
at least six months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 7.09 and shall fail to resign after written request therefor by the Company or by
any such Noteholder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation,

then, in any such case, the Company may remove the Trustee and appoint a successor trustee by
written instrument, in duplicate, executed by order of the Company’s Board of Directors, one copy
of which instrument shall be delivered to the Trustee so removed and one copy to the successor
trustee, or, subject to the provisions of Section 6.09, any Noteholder who has been a bona fide
holder of a Note or Notes for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor trustee; provided that if no successor Trustee shall have been
appointed and have accepted appointment 60 calendar days after either the Company or the
Noteholders has removed the Trustee, or the Trustee resigns, the Trustee so removed may petition,
at the expense of the Company, any court of competent jurisdiction for an appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

(c) The holders of a majority in aggregate Principal Amount of the Notes at the time
outstanding may at any time remove the Trustee and nominate a successor trustee which shall be
deemed appointed as successor trustee unless, within ten calendar days after notice to the Company
of such nomination, the Company objects thereto, in which case the Trustee so removed or any
Noteholder, or if such Trustee so removed or any Noteholder fails to act, the Company, upon the
terms and conditions and otherwise as in Section 7.10(a) provided, may petition any court of
competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 7.10 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 7.11.

Section 7.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 7.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section
7.06, execute and deliver an instrument transferring to such successor trustee all the rights and
powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company
shall execute any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of holders of particular Notes, to secure any
amounts then due it pursuant to the provisions of Section 7.06.

No successor trustee shall accept appointment as provided in this Section 7.11 unless, at the
time of such acceptance, such successor trustee shall be qualified under the provisions of Section
7.08 and be eligible under the provisions of Section 7.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.11, the
Company (or the former trustee, at the written direction and the expense of the Company) shall mail
or cause to be mailed notice of the succession of such trustee hereunder to the holders of Notes at
their addresses as they shall appear on the Note Register. If the Company fails to mail such
notice within ten (10) calendar days after acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 7.12. Succession by Merger. Any Person into which the Trustee may be merged or
converted or with which it may be consolidated, or any Person resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any Person succeeding to all or
substantially all of the corporate trust business of the Trustee (including any trust created by
this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of
any paper or any further act on the part of any of the parties hereto, provided that in the case of
any Person succeeding to all or substantially all of the corporate trust business of the Trustee,
such Person shall be qualified under the provisions of Section 7.08 and eligible under the
provisions of Section 7.09.

In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or any authenticating agent appointed by such successor trustee may
authenticate such Notes in the name of the successor trustee; and in all such cases such
certificates shall have the full force that is provided in the Notes or in this Indenture; provided
that the right to adopt the certificate of authentication of any predecessor Trustee or
authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or
successors by merger, conversion or consolidation.

Section 7.13. Preferential Collection of Claims. If and when the Trustee shall be or become a
creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of the claims against the Company
(or any such other obligor).

ARTICLE 8

The Noteholders

Section 8.01. Action by Noteholders. Whenever in this Indenture it is provided that the
holders of a specified percentage in aggregate Principal Amount of the Notes may take any action
(including the making of any demand or request, the giving of any notice, consent or waiver or the
taking of any other action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any instrument or any number
of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in
writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of
Noteholders duly called and held in accordance with the provisions of Article 9, or (c) by a
combination of such instrument or instruments and any such record of such a meeting of Noteholders.
Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes,
the Company or the Trustee may fix in advance of such solicitation, a date as the record date for
determining holders entitled to take such action. The record date shall be not more than fifteen
calendar days prior to the date of commencement of solicitation of such action.

Section 8.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 7.01,
7.02 and 9.05, proof of the execution of any instrument by a Noteholder or its agent or proxy shall
be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed
by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes
shall be proved by the registry of such Notes or by a certificate of the Note Registrar.

The record of any Noteholders’ meeting shall be proved in the manner provided in Section 9.06.

Section 8.03. Who Are Deemed Absolute Owners. The Company, the Issuer, any Subsidiary
Guarantor, the Trustee, any Paying Agent, any Exchange Agent and any Note Registrar may deem the
Person in whose name such Note shall be registered upon the Note Register to be, and may treat it
as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding
any notation of ownership or other writing thereon made by any Person other than the Company or any
Note Registrar) for the purpose of receiving payment of or on account of the Principal Amount of
and Interest on such Note, for exchange of such Note and for all other purposes; and none of the
Company, the Issuer, any Subsidiary Guarantor, the Trustee, any Paying Agent, any Exchange Agent or
any Note Registrar shall be affected by any notice to the contrary. All such payments so made to
any holder for the time being, or upon his order, shall be valid, and, to the extent of the sum or
sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such
Note.

Section 8.04. Company-owned Notes Disregarded. In determining whether the holders of the
requisite aggregate Principal Amount of Notes have concurred in any direction, consent, waiver or
other action under this Indenture, Notes which are owned by the Company or any other obligor on the
Notes or any Affiliate of the Company or any other obligor on the Notes shall be disregarded and
deemed not to be outstanding for the purpose of any such determination; provided that for the
purposes of determining whether the Trustee shall be protected in relying on any such direction,
consent, waiver or other action, only Notes which a Responsible Officer actually knows are so owned
shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the
Company, any other obligor on the Notes or any Affiliate of the Company or any such other obligor.
In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of
counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any,
known by the Company to be owned or held by or for the account of any of the above described
Persons, and, subject to Section 7.01, the Trustee shall be entitled to accept such Officers’
Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes
not listed therein are outstanding for the purpose of any such determination.

Section 8.05. Revocation of Consents, Future Holders Bound. At any time prior to (but not
after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by
the holders of the percentage in aggregate Principal Amount of the Notes specified in this
Indenture in connection with such action, any holder of a Note which is shown by the evidence to be
included in the Notes the holders of which have consented to such action may, by filing written
notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such
action taken by the holder of any Note shall be conclusive and binding upon such holder and upon
all future holders and owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note
issued in exchange or substitution therefor.

ARTICLE 9

(b) Subject to the provisions of Section 11.02 and 15.02(b), a Subsidiary Guarantor shall not
consolidate or merge with or into any other Person (whether or not affiliated with such Subsidiary
Guarantor), nor shall any Subsidiary Guarantor or its successor or successors be a party or parties
to successive consolidations or mergers, nor shall any Subsidiary Guarantor sell, convey, transfer
or lease all or substantially all the assets of such Subsidiary Guarantor, to any other Person
(whether or not affiliated with such Subsidiary Guarantor), unless:

(i) (x) the Subsidiary Guarantors is the surviving Person or (y) the resulting,
surviving or transferee Person is a corporation, limited liability company or partnership
organized and existing under the laws of the United States of America, any state thereof or
the District of Columbia and, upon any such consolidation, merger, sale, conveyance,
transfer or lease, expressly assumes, all obligations of such Subsidiary Guarantor under
this Indenture and, to the extent a party thereto, the Registration Rights Agreement by
supplemental indenture in form reasonably satisfactory to the Trustee, and by supplemental
agreement;

(ii) immediately after giving effect to the transaction described above, no Default or
Event of Default shall have occurred and be continuing; and

(iii) such Subsidiary Guarantor shall have delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel, if any, requested pursuant to Section 11.03.

Section 11.02. Successor to Be Substituted. (a) In case of any such consolidation, merger,
sale, conveyance, transfer or lease in which the Company or the Issuer, as the case may be, is not
the surviving Person 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 due and
punctual payment of the Principal Amount of and Interest on all of the Notes and the due and
punctual performance of all of the covenants and conditions of this Indenture to be performed or
satisfied by the Company or the Issuer, as the case may be, and by supplemental agreement, executed
and delivered to the Trustee, of all of the obligations of the Company or the Issuer, as the case
may be, under the Registration Rights Agreement, such successor Person shall succeed to and be
substituted for the Company or the Issuer, as the case may be, with the same effect as if it had
been named herein as the party of this first part. Such successor Person thereupon may cause to be
signed, and may issue either in its own name or in the name of CSK Auto, Inc. any or all of the
Notes, issuable hereunder that theretofore shall not have been signed by the Company and delivered
to the Trustee; and, upon the order of such successor Person instead of the Company and subject to
all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that
previously shall have been signed and delivered by the officers of the Company to the Trustee for
authentication, and any Notes that such successor Person thereafter shall cause to be signed and
delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the
same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Notes had been issued at the date
of the execution hereof. In the event of any such consolidation, merger, sale, conveyance,
transfer or lease, the Person named as the “Company” or “Issuer”, as the case may be, in the first
paragraph of this Indenture or any successor that shall thereafter have become such in the manner
prescribed in this Article 11 may be dissolved, wound up and liquidated at any time thereafter and
such Person shall be released from its liabilities as obligor and maker of the Notes and from its
obligations under this Indenture.

(b) In case of any such consolidation, merger, sale, conveyance, transfer or lease in which a
Subsidiary Guarantor is not the surviving Person 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 due and punctual performance and observance of all of the covenants and conditions
of this Indenture to be performed or satisfied by such Subsidiary Guarantor and by supplemental
agreement, executed and delivered to the Trustee, of all of the obligations of such Subsidiary
Guarantor under the Registration Rights Agreement to the extent a party thereto, such successor
Person shall succeed to and be substituted for such Subsidiary Guarantor, with the same effect as
if it had been named herein as a Subsidiary Guarantor as of the date of this Indenture. Such
successor Person thereupon may cause to be signed, and may issue either in its own name or in the
name of such Subsidiary Guarantor the Subsidiary Guarantee of such Subsidiary Guarantor, issuable
hereunder that theretofore shall not have been signed by such Subsidiary Guarantor and delivered to
the Trustee. All the Subsidiary Guarantees of the Subsidiary Guarantors so issued shall in all
respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantee of
the Subsidiary Guarantors theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution
hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in
the case of a lease), the applicable Person named as a “Subsidiary Guarantor” in this Indenture or
any supplemental indenture hereto or any successor that shall thereafter have become such in the
manner prescribed in this Article 11 may be dissolved, wound up and liquidated at any time
thereafter and such Person shall be released from its liabilities as obligor and maker of its
Subsidiary Guarantee and from its obligations under this Indenture and its Subsidiary Guarantee.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes
in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as
may be appropriate.

Section 11.03. Opinion of Counsel to Be Given Trustee. The Trustee shall receive an Officers’
Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or lease and any such assumption complies with the provisions of this
Article 11.

ARTICLE 12

the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by
Section 16.05 and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees
to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by
the Trustee and to compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Notes.

Section 12.02. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this
Indenture, all monies then held by any Paying Agent of the Notes (other than the Trustee) shall,
upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such
Paying Agent shall be released from all further liability with respect to such monies.

Section 12.03. Return of Unclaimed Monies. Subject to the requirements of applicable law, any
monies deposited with or paid to the Trustee for payment of the Principal Amount of or Interest on
Notes and not applied but remaining unclaimed by the holders of Notes for two years after the date
upon which the Principal Amount of or Interest on such Notes, as the case may be, shall have become
due and payable, shall be repaid to the Company by the Trustee on written demand and all liability
of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the
Notes shall thereafter look only to the Company for any payment that such holder may be entitled to
collect unless an applicable abandoned property law designates another Person.

ARTICLE 13

Immunity of Incorporators, Stockholders, Officers and Directors

Section 13.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment
of the Principal Amount of or Interest on any Note, or for any claim based thereon or otherwise in
respect thereof, and no recourse under or upon any obligation, covenant or agreement of the
Company, the Issuer or the Subsidiary Guarantors in this Indenture or in any supplemental indenture
or in any Note, or of the Issuer and the Subsidiary Guarantors under the Guarantees or because of
the creation of any indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of
the Company, the Issuer or the Subsidiary Guarantors or of any successor corporation, either
directly or through the Company, the Issuer or the Subsidiary Guarantors or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement
of any assessment or penalty or otherwise; it being expressly understood that all such liability is
hereby expressly waived and released as a condition of, and as a consideration for, the execution
of this Indenture and the issue of the Notes.

ARTICLE 14

Exchange of Notes

Section 14.01. Right to Exchange. (a) Subject to and upon compliance with the provisions of
this Indenture, at any time prior to 5:00 p.m., New York City time, on the Trading Day immediately
preceding the Stated Maturity, the holder of any Note shall have the right, at such holder’s
option, to exchange each $1,000 Principal Amount of the Notes, and integral multiples thereof, into
cash or a combination of cash and fully paid and non-assessable shares of Common Stock (as such
shares shall then be constituted) at the Exchange Rate in effect at such time, subject to Section
14.01(d), by surrender of the Note so to be exchanged in whole or in part, together with any
required funds, under the circumstances described in this Section 14.01 and in the manner provided
in Section 14.02. The Notes shall be exchangeable only during the following periods upon the
occurrence of one of the following events:

(i) during any fiscal quarter (and only during such fiscal quarter) commencing after
January 29, 2006, if the Last Reported Sale Price of the Common Stock for at least 20
Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day
of the preceding fiscal quarter is greater than or equal to 130% of the applicable Exchange
Price on such last Trading Day;

(ii) in the event that the Company calls any or all of the Notes for redemption, at any
time prior to 5:00 p.m., New York City time, on the second Trading Day immediately preceding
the Redemption Date at which time the right to exchange such Notes will expire, unless the
Company fails to pay the Redemption Price; provided that only those Notes that are called
for redemption may be exchanged following such an event; or

(iii) as provided in Section (b) of this Section 14.01.

(b) In addition, if:

(i) (A) the Issuer distributes to all or substantially all holders of Common Stock
rights or warrants entitling them to subscribe for or purchase (for a period expiring within
45 calendar days of the date of the distribution) shares of Common Stock at less than the
Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the
declaration date of the distribution, or (B) the Issuer distributes to all or substantially
all holders of Common Stock, assets, debt securities or rights to purchase securities of the
Issuer, which distribution has a per share value as determined by the Company’s Board of
Directors and set forth in a Company Board Resolution exceeding 15% of the Last Reported
Sale Price of the Common Stock on the Trading Day immediately preceding the declaration date
for such distribution, then, in either case, the Notes may be surrendered for exchange at
any time on and after the date that the Issuer gives notice to the holders of such
distribution, which shall be not less than 20 Business Days prior to the Ex-Dividend Date
for such distribution, until the earlier of 5:00 p.m., New York City time, on the Business
Day immediately preceding, but not including, the Ex-Dividend Date or the date the Issuer
publicly announces that such distribution will not take place; provided that no holder may
exchange Notes in accordance with this Section 14.01(b)(i) if the holder will otherwise
participate in such distribution without exchange as a result of holding the Notes;

(ii) the Issuer consolidates with or merges with or into another Person, is a party to
a binding share exchange or conveys, transfers, sells, leases or otherwise disposes of all
or substantially all of its assets, in each case pursuant to which the Common Stock would be
converted into (A) cash or property other than securities, or (B) cash, securities or other
property, provided that in the case of clause (B), such transaction also constitutes a
Fundamental Change, then the Notes may be surrendered for exchange at any time beginning 25
calendar days prior to the anticipated effective date of the transaction until and including
the date which is 25 calendar days after the actual effective date of the transaction (or if
such consolidation, merger, share exchange or transfer also constitutes a Fundamental
Change, until the Fundamental Change Repurchase Date corresponding to such Fundamental
Change). The Company’s Board of Directors shall determine the anticipated Effective Date of
the transaction, and such determination shall be conclusive and binding on the holders and
shall be publicly announced by the Company by publication on its Web site or through such
other public medium as it may use at that time not later than two Business Days prior to
such 25th calendar day;

(iii) a Fundamental Change of the type described in clause (i) of the definition of
Fundamental Change occurs, holders may surrender Notes for exchange at any time beginning on
the actual Effective Date of such Fundamental Change until and including the date which is
30 calendar days after the Effective Date of such transaction or if, later, until the
Fundamental Change Repurchase Date corresponding to such Fundamental Change.

(c) Whenever the Notes shall become exchangeable pursuant to this Section 14.01, the Company
or, at the Company’s request, and after the Company has prepared and delivered such notice to the
Trustee, the Trustee in the name and at the expense of the Company, shall notify the holders of the
event triggering such exchangeability in the manner provided in Section 16.03, and the Company
shall also publicly announce such information by publication on the Company’s Web site or through
such other public medium as it may use at such time. Any notice so given shall be conclusively
presumed to have been duly given, whether or not the holder receives such notice.

The Company or its designated agent shall determine on a daily basis during the last 20
Trading Days of each fiscal quarter (until such day, if any, as the Notes are determined to be
exchangeable) whether the Notes shall be exchangeable as a result of the occurrence of an event
specified in Section 14.01(a)(i) and, if the Notes shall be so exchangeable, the Company shall
promptly deliver to the Exchange Agent written notice thereof.

(d) A Note in respect of which a holder is electing to exercise its option to require
repurchase upon a Fundamental Change pursuant to Section 3.04 or repurchase pursuant to Section
3.05 may be exchanged only if such holder withdraws its election in accordance with Section
3.06(d). A holder of Notes is not entitled to any rights of a holder of Common Stock until such
holder has exchanged his Notes into Common Stock, and only to the extent such Notes are deemed to
have been exchanged to Common Stock under this Article 14.

(e) If a Noteholder elects to exchange its notes in connection with a specified corporate
transaction pursuant to Section 14.01(b) that occurs prior to December 15, 2010, and the corporate
transaction also constitutes a Fundamental Change as described in clause (i) or (ii) of the
definition thereof, subject to Section 14.07, the Exchange Rate shall be increased by an additional
number of shares of Common Stock (the “Additional Shares”) as described below, provided that if the
Stock Price is greater than $60.00 or less than $14.59 (subject in each case to adjustment as
described below), the number of Additional Shares shall be zero. Notwithstanding the foregoing, in
no event will the Exchange Rate be increased pursuant to this Section 14.01(e) to a rate that would
exceed 68.4501 shares, subject to adjustments in the same manner as the Exchange Rate as set forth
in Section 14.05 per $1,000 Principal Amount of Notes.

The number of Additional Shares will be determined by reference to the table attached as
Schedule A hereto, based on the actual effective date of such corporate transaction (the “Effective
Date”) and the Stock Price with respect to such corporate transaction; provided that if the Stock
Price is between two Stock Price amounts in the table or the Effective Date is between two
Effective Dates in the table, the number of Additional Shares will be determined by a straight-line
interpolation between the number of Additional Shares set forth for the higher and lower Stock
Price amounts and the two dates, as applicable, based on a 365-day year.

The Stock Prices set forth in the first row of the table in Schedule A hereto and set forth in
the first paragraph of this Section 14.01(e) will be adjusted as of any date on which the Exchange
Rate of the Notes is adjusted pursuant to Section 14.05. The adjusted Stock Prices will equal the
Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the
numerator of which is the Exchange Rate immediately prior to such adjustment and the denominator of
which is the Exchange Rate as so adjusted. The number of Additional Shares will be adjusted in the
same manner as the Exchange Rate as set forth in Section 14.05.

Any exchange of Notes occurring at a time when the Notes would be exchangeable in light of the
expected or actual occurrence of a Fundamental Change will be deemed to have occurred in connection
with such Fundamental Change notwithstanding the fact that a Note may then be exchangeable because
another condition to exchange has been satisfied.

Section 14.02. Exercise of Exchange Right; Issuance of Common Stock on Exchange; No Adjustment
for Interest or Dividends. In order to exercise the exchange right with respect to any Note in
certificated form, the Company must receive at the office or agency of the Company maintained for
that purpose or, at the option of such holder, the Corporate Trust Office, such Note with the
original or facsimile of the form entitled “Form of Exchange Notice” on the reverse thereof, which
is irrevocable, duly completed and manually signed, together with such Notes duly endorsed for
transfer. Such notice shall also state the name or names (with address or addresses) in which the
certificate or certificates for shares of Common Stock which shall be issuable on such exchange
shall be issued, and to whom the cash payable on such exchange shall be delivered, and shall be
accompanied by transfer or similar taxes, if required pursuant to Section 14.08, and funds equal to
the Interest payable on the next Interest Payment Date to which such holder of the Note is not
entitled, if required pursuant to this Section 14.02.

In order to exercise the exchange right with respect to any interest in a Global Note, the
beneficial holder must complete, or cause to be completed, the appropriate instruction form for
exchange pursuant to the Depositary’s book-entry exchange program, deliver, or cause to be
delivered, by book-entry delivery an interest in such Global Note, furnish appropriate endorsements
and transfer documents if required by the Company or the Trustee or Exchange Agent, and pay the
funds, if any, required by this Section 14.02 and any transfer taxes if required pursuant to
Section 14.08.

The Company will deliver the Settlement Amount to exchanging holders on the second Business
Day immediately following the last day of the Cash Settlement Averaging Period, or in the case of
an optional redemption pursuant to Section 3.02, the Redemption Date. Subject to compliance with
any restrictions on transfer if shares issuable on exchange are to be issued in a name other than
that of the Noteholder (as if such transfer were a transfer of the Note or Notes (or portion
thereof) so exchanged), the Company shall issue and shall deliver through the Exchange Agent to
such Noteholder at the office or agency maintained by the Company for such purpose pursuant to
Section 4.02, a check or cash in respect of the lesser of the aggregate Principal Amount of Notes
being exchanged and the Exchange Value in respect of such Notes, calculated by the Company as
provided in Section 14.03 and a certificate or certificates for the number of full shares of Common
Stock, if any, issuable upon the exchange of such Note or Notes (or portion thereof) so exchanged
as determined by the Company as provided in Section 14.03, or if the Common Stock is eligible for
transfer through The Depository Trust Company, the Company shall make a book-entry transfer of such
number of shares of Common Stock through The Depository Trust Company, and a check or cash in
respect of any fractional interest in respect of any share of Common Stock arising upon such
exchange. In case any Note of a denomination greater than $1,000 shall be surrendered for partial
exchange, and subject to Section 2.03, the Company shall execute and the Trustee shall authenticate
and deliver to the holder of the Note so surrendered, without charge to him, a new Note or Notes in
authorized denominations in an aggregate Principal Amount equal to the unexchanged portion of the
surrendered Note.

Each exchange shall be deemed to have been effected as to any such Note (or portion thereof)
on the date on which the requirements set forth above in this Section 14.02 have been satisfied as
to such Note (or portion thereof) (such date, the “Exchange Date”), and the Person in whose name
any certificate or certificates for shares of Common Stock shall be issuable upon such exchange
shall be deemed to have become on said date the holder of record of the shares represented thereby;
provided that any such surrender on any date when the stock transfer books of the Company shall be
closed shall constitute the Person in whose name the certificates are to be issued as the record
holder thereof for all purposes on the next succeeding day on which such stock transfer books are
open, but such exchange shall be at the Exchange Rate in effect on the date upon which such Note
shall be surrendered.

Any Note or portion thereof surrendered for exchange during the period from 5:00 p.m., New
York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the corresponding
Interest Payment Date shall be accompanied by payment, in immediately available funds or other
funds acceptable to the Company, of an amount equal to the Interest otherwise payable on such
Interest Payment Date on the Principal Amount being exchanged; provided that no such payment need
be made (1) if the Company has specified a Redemption Date that is after a Regular Record Date and
on or prior to the third Trading Day after the corresponding Interest Payment Date, (2) if the
Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and
on or prior to the Trading Day after the corresponding Interest Payment Date or (3) to the extent
of any overdue Interest, if any overdue Interest exists at the time of exchange with respect to
such Note. Except as provided above in this Section 14.02, no payment or other adjustment shall be
made for Interest accrued on any Note exchanged or for dividends on any shares issued upon the
exchange of such Note as provided in this Article 14.

Upon the exchange of an interest in a Global Note, the Exchange Agent, or the Custodian at the
direction of the Exchange Agent, shall make a notation on such Global Note as to the reduction in
the Principal Amount represented thereby. The Company shall notify the Trustee in writing of any
exchanges of Notes effected through any Exchange Agent other than the Trustee.

Upon the exchange of a Note, that portion of the accrued but unpaid Interest with respect to
the exchanged Note shall not be cancelled, extinguished or forfeited, but rather shall be deemed to
be paid in full to the holder thereof through delivery of cash or a combination of cash and the
Common Stock, as the case may be (together with the cash payment in lieu of fractional shares, if
any) in exchange for the Note being exchanged pursuant to the provisions hereof; and cash or a
combination of cash and shares of Common Stock, as the case may be (together with any such cash
payment in lieu of fractional shares) shall be treated as issued, to the extent thereof, first in
exchange for and in satisfaction of the Company’s obligation to pay the Principal Amount of the
exchanged Note and the accrued but unpaid Interest, and the balance, if any, of such fair market
value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for
and in satisfaction of the right to exchange the Note being exchanged pursuant to the provisions
hereof.

Section 14.03. Payment Upon Exchange; Cash Payments in Lieu of Fractional Shares. (a) Upon
receipt of a notice of exchange, the Company will deliver to holders in respect of each $1,000
Principal Amount of Notes being exchanged a settlement amount (the “Settlement Amount”) consisting
of (i) cash equal to the lesser of $1,000 and the Exchange Value and (ii) to the extent the
Exchange Value exceeds $1,000, a number of shares equal to the sum of, for each day of the 20
Trading Day Cash Settlement Averaging Period, (A) 5% of the difference between the Exchange Value
and $1,000, divided by (B) the Last Reported Sale Price of the Common Stock for such day.

(b) If more than one Note shall be surrendered for exchange at one time by the same holder,
the number of full shares that shall be issuable upon exchange, if any, shall be computed on the
basis of the aggregate principal amount of Notes so surrendered. No fractional shares of Common
Stock shall be issued upon exchange of Notes. If any fractional share of Common Stock would be
issuable upon the exchange of any Note or Notes, the Company shall make an adjustment and payment
therefor in cash to the holder of Notes at a price equal to the average of the Last Reported Sale
Price of the Common Stock over the Cash Settlement Averaging Period.

Section 14.04. Exchange Rate. Each $1,000 Principal Amount of the Notes shall be exchangeable
into the number of shares of Common Stock specified in the form of Note (herein called the
“Exchange Rate”) attached as Exhibit A hereto (initially 49.8473 shares), subject to adjustment as
provided in this Article 14.

Section 14.05. Adjustment of Exchange Rate. The Exchange Rate shall be adjusted from time to
time by the Company as follows:

(a) If the Issuer issues shares of Common Stock as a dividend or distribution on shares of the
Common Stock, or effects a share split or share combination, the Exchange Rate will be adjusted
based on the following formula:

	 	 	 	 	 	 	 
	ER’=

	 	ER0
	 	×
	 	OS’
	 
	 	 	 	 	 	 
	
 
	 	OS0
	 	

	 	

	 	 	 	 	 
	where,

ER0

ER’

	 	

=

=
	 	

the Exchange Rate in effect immediately prior to such event

the Exchange Rate in effect immediately after such event

	 	 	 	OS0 = the number of shares of Common Stock outstanding immediately prior
to such event	 

	 	 	 	OS’ = the number of shares of Common Stock outstanding immediately after
such event.	 

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the
Business Day following the date fixed for such determination. If any dividend or distribution of
the type described in this Section 15.05(a) is declared but not so paid or made, the Exchange Rate
shall again be adjusted to the Exchange Rate that would then be in effect if such dividend or
distribution had not been declared.

(b) If the Issuer issues to all or substantially all holders of its Common Stock any rights or
warrants entitling such holders for a period of not more than 45 calendar days to subscribe for or
purchase shares of Common Stock, at a price per share less than the Last Reported Sale Price of
Common Stock on the Business Day immediately preceding the date of announcement of such issuance,
the Exchange Rate will be adjusted based on the following formula:

	 	 	 
	ER’=ER0 ×

	 	OS0 + X
	 
	 	 
	
 
	 	OS0 + Y

	 	 	 	 	 
	where,

ER0

ER’

	 	

=

=
	 	

the Exchange Rate in effect immediately prior to such event

the Exchange Rate in effect immediately after such event

	 	 	 	OS0 = the number of shares of Common Stock outstanding immediately prior
to such event	 

	 	 	 	X = the total number of shares of Common Stock issuable pursuant to such
rights or warrants	 

	 	 	 	Y = the number of shares of Common Stock equal to the aggregate price
payable to exercise such rights divided by the average of the Last Reported
Sale Prices of Common Stock over the ten consecutive Trading Day period ending
on the Business Day immediately preceding the Stock Record Date for the
issuance of such rights or warrants.	 

Such adjustment shall be successively made whenever any such rights or warrants are issued and
shall become effective immediately after 9:00 a.m., New York City time, on the Business Day
following the date fixed for such determination. To the extent that shares of Common Stock are not
delivered prior to the expiration of such rights or warrants, the Exchange Rate shall be readjusted
to the Exchange Rate that would then be in effect had the adjustments made upon the issuance of
such rights or warrants been made on the basis of delivery of only the number of shares of Common
Stock actually delivered. If such rights or warrants are not so issued, the Exchange Rate shall
again be adjusted to be the Exchange Rate that would then be in effect if such date fixed for the
determination of stockholders entitled to receive such rights or warrants had not been fixed.

In determining whether any rights or warrants entitle the holders to subscribe for or purchase
shares of Common Stock at less than such Last Reported Sale Price, and in determining the aggregate
offering price of such shares of Common Stock, there shall be taken into account any consideration
received by the Issuer for such rights or warrants and any amount payable on exercise or conversion
thereof, the value of such consideration, if other than cash, to be determined by the Company’s
Board of Directors.

(c) If the Issuer distributes shares of its capital stock, evidences of its indebtedness or
other assets or property of the Issuer to all or substantially all holders of the Common Stock,
excluding:

(i) dividends or distributions and rights or warrants referred to in clause (a) or (b)
above; and

(ii) dividends or distributions paid exclusively in cash;

then the Exchange Rate will be adjusted based on the following formula:

	 	 	 
	ER’=ER0 ×

	 	SP0
	 
	 	 
	
 
	 	SP0 – FMV

where,

	 	 	 	ER0 = the Exchange Rate in effect immediately prior to such distribution	 

	 	 	 	ER’ = the Exchange Rate in effect immediately after such distribution	 

	 	 	 	SP0 = the average of the Last Reported Sale Prices of the Common Stock
over the ten consecutive Trading Day period ending on the Business Day
immediately preceding the ex-date for such distribution	 

	 	 	 	FMV = the fair market value (as determined by the Company’s Board of
Directors) of the shares of capital stock, evidences of indebtedness, assets or
property distributed with respect to each outstanding share of Common Stock on
the Stock Record Date for such distribution.	 

Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the
Business Day following the date fixed for the determination of stockholders entitled to receive
such distribution.

With respect to an adjustment pursuant to this clause (c) where there has been a payment of a
dividend or other distribution on the Common Stock or shares of capital stock of any class or
series, or similar equity interest, of or relating to a subsidiary or other business unit (a
“Spin-Off”) the Exchange Rate in effect immediately before 5:00 p.m., New York City time, on the
Stock Record Date fixed for determination of stockholders entitled to receive the distribution will
be increased based on the following formula:

	 	 	 
	ER’=ER0 ×

	 	FMV0 + MP0
	 
	 	 
	
 
	 	MP0

where,

	 	 	 	ER0 = the Exchange Rate in effect immediately prior to such distribution	 

	 	 	 	ER’ = the Exchange Rate in effect immediately after such distribution	 

	 	 	 	FMV0 = the average of the Last Reported Sale Prices of the capital stock
or similar equity interest distributed to holders of Common Stock applicable to
one share of Common Stock over the first ten consecutive Trading Day period
after the effective date of the Spin-Off	 

	 	 	 	MP0 = the average of the Last Reported Sale Prices of Common Stock over
the first ten consecutive Trading Day period after the effective date of the
Spin-Off.	 

Such adjustment shall occur on the tenth Trading Day from, and including, the effective date of
the Spin-Off.

(d) If the Issuer makes any cash dividend or distribution during any of the Issuer’s quarterly
fiscal period to all or substantially all holders of Common Stock, the Exchange Rate will be
adjusted based on the following formula:

	 	 	 
	ER’=ER0 ×

	 	SP0
	 
	 	 
	
 
	 	SP0 – C

where,

	 	 	 	ER0 = the Exchange Rate in effect immediately prior to the Stock Record
Date for such dividend or distribution	 

	 	 	 	ER’ = the Exchange Rate in effect immediately after the Stock Record Date
for such dividend or distribution	 

	 	 	 	SP0 = the average of the Last Reported Sale Prices of the Common Stock
over the ten consecutive Trading Day period ending on the Business Day
immediately preceding the ex-date for such dividend or distribution	 

	 	 	 	C = the amount in cash per share the Issuer dividends or distributes to
holders of Common Stock.	 

Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the
date for such determination.

(e) If the Issuer or any of its subsidiaries purchases shares of Common Stock pursuant to a
tender or exchange offer which involves an aggregate per share consideration that exceeds the Last
Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which
tenders or exchanges may be made pursuant to such tender or exchange offer (such last date, the
“Expiration Time”), the Exchange Rate will be adjusted based on the following formula:

	 	 	 
	ER’=ER0 ×

	 	AC + (SP’×OS’)
	 
	 	 
	
 
	 	OS0 × SP’

where,

	 	 	 	ER0 = the Exchange Rate in effect on the date such tender or exchange
offer expires	 

	 	 	 	ER’ = the Exchange Rate in effect on the day next succeeding the date such
tender or exchange offer expires	 

	 	 	 	AC = the aggregate value of all cash and any other consideration (as
determined by the Company’s Board of Directors) paid or payable for shares
purchased in such tender or exchange offer	 

	 	 	 	OS0 = the number of shares of Common Stock outstanding immediately prior
to the date such tender or exchange offer expires	 

	 	 	 	OS’ = the number of shares of Common Stock outstanding immediately after
the date such tender or exchange offer expires	 

	 	 	 	SP’ = the average of the Last Reported Sale Prices of Common Stock over the
ten consecutive Trading Day period commencing on the Trading Day next
succeeding the date such tender or exchange offer expires.	 

If the Issuer is obligated to purchase shares pursuant to any such tender or exchange offer, but
the Issuer is permanently prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Exchange Rate shall again be adjusted to be the Exchange Rate that
would then be in effect if such tender or exchange offer had not been made.

If, however, the application of the foregoing formula would result in a decrease in the Exchange
Rate, no adjustment to the Exchange Rate will be made.

(f) Notwithstanding the foregoing provisions of this Section 14.05, no adjustment shall be
made thereunder, nor shall an adjustment be made to the ability of a holder of a Note to exchange,
for any distribution described therein if the holder will otherwise participate in the distribution
without exchange of such holder’s Notes.

(g) The Company may (but is not required to) make such increases in the Exchange Rate, in
addition to those required by clauses (a) through (e) of this Section 14.05 as the Company’s Board
of Directors considers to be advisable to avoid or diminish any income tax to holders of Common
Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares
(or rights to acquire shares) or any similar event treated as such for income tax purposes.

To the extent permitted by applicable law, the Company from time to time may increase the
Exchange Rate by any amount for any period of at least 20 days if the Company’s Board of Directors
shall have made a determination that such increase would be in the best interests of the Company,
which determination shall be conclusive.

(h) All calculations under this Article 14 shall be made by the Company and shall be made to
the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be.
The Company will not be required to make an adjustment in the Exchange Rate unless the adjustment
would require a change of at least 1% in the Exchange Rate. However, the Company will carry forward
any adjustments that are less than 1% of the Exchange Rate and make such carried forward
adjustments, regardless of whether aggregate adjustment is less than 1% within one year of the
first such adjustment carried forward, upon redemption, upon a Fundamental Change or upon the
Stated Maturity.

To the extent the Notes become exchangeable into cash, assets or property (other than capital
stock of the Issuer or securities to which Section 14.06 or 14.07 applies), no adjustment shall be
made thereafter pursuant to this Section 14.05 as to the cash, assets or property.

(i) Whenever the Exchange Rate is adjusted as herein provided, the Company shall promptly file
with the Trustee and any Exchange Agent other than the Trustee an Officers’ Certificate setting
forth the Exchange Rate after such adjustment and setting forth a brief statement of the facts
requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Exchange Rate and may assume that the last Exchange Rate of which it has
knowledge is still in effect. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Exchange Rate setting forth the adjusted Exchange Rate
and the date on which each adjustment becomes effective.

The Company or, at the Company’s request after the Company has prepared and delivered such
notice to the Trustee, the Trustee in the name and at the expense of the Company, shall notify the
holders of the adjustment to the Exchange Rate in the manner provided in Section 16.03, and the
Company shall also publicly announce such information by publication on the Company’s Web site or
through such other public medium as it may use at such time. Any notice so given shall be
conclusively presumed to have been duly given, whether or not the holder receives such notice.
Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(j) In any case in which this Section 14.05 provides that an adjustment shall become effective
immediately after (1) a record date or Stock Record Date for an event, (2) the date fixed for the
determination of stockholders entitled to receive a dividend or distribution pursuant to Section
14.05(a), (3) a date fixed for the determination of stockholders entitled to receive rights or
warrants pursuant to Section 14.05(b) or (4) the Expiration Time for any tender or exchange offer
pursuant to Section 14.05(e), (each a “Determination Date”), the Company may elect to defer until
the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the
holder of any Note exchanged after such Determination Date and before the occurrence of such
Adjustment Event, the additional shares of Common Stock or other securities issuable upon such
exchange by reason of the adjustment required by such Adjustment Event over and above the Common
Stock issuable upon such exchange before giving effect to such adjustment and (y) paying to such
holder any amount in cash in lieu of any fraction pursuant to Section 14.03. For purposes of this
Section 14.05(j), the term “Adjustment Event” shall mean:

(i) in any case referred to in clause (1) hereof, the occurrence of such event,

(ii) in any case referred to in clause (2) hereof, the date any such dividend or
distribution is paid or made,

(iii) in any case referred to in clause (3) hereof, the date of expiration of such
rights or warrants, and

(iv) in any case referred to in clause (4) hereof, the date a sale or exchange of
Common Stock pursuant to such tender or exchange offer is consummated and becomes
irrevocable.

(k) For purposes of this Section 14.05, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Issuer but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.
The Issuer will not pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Issuer. The Issuer shall not issue any such rights, options or warrants in respect
of shares of Common Stock held in treasury by the Issuer.

Section 14.06. Effect of Reclassification, Consolidation, Merger or Sale. If any of the
following events occur (i) any reclassification or change of the outstanding shares of Common Stock
(other than a subdivision or combination to which Section 14.05(c) applies), (ii) any
consolidation, merger, binding share exchange or combination of the Issuer with another Person as a
result of which holders of Common Stock shall be entitled to receive cash, securities or other
property with respect to or in exchange for such Common Stock, or (iii) any sale, lease, conveyance
or other transfer of all or substantially all of the properties and assets of the Issuer to any
other Person as a result of which holders of Common Stock shall be entitled to receive cash,
securities or other property with respect to or in exchange for such Common Stock, then the Issuer
and the Company or the successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at
the date of execution of such supplemental indenture) providing that each Note shall be
exchangeable into the kind and amount of cash, securities or other property (and in the same
proportion) receivable (the “Applicable Consideration”) upon such reclassification, change,
consolidation, merger, binding share exchange, combination, sale or conveyance by a holder of a
number of shares of Common Stock issuable upon exchange of such Notes (assuming, for such purposes,
a sufficient number of authorized shares of Common Stock are available to exchange all such Notes)
immediately prior to such reclassification, change, consolidation, merger, binding share exchange,
combination, sale or conveyance assuming such holder of Common Stock did not exercise his rights of
election, if any, as to the kind or amount of cash, securities or other property receivable upon
such reclassification, change, consolidation, merger, binding share exchange, combination, sale or
conveyance (provided that, if the kind or amount of cash, securities or other property receivable
upon such reclassification, change, consolidation, merger, binding share exchange, combination,
sale or conveyance is not the same for each share of Common Stock in respect of which such rights
of election shall not have been exercised (“non-electing share”), then for the purposes of this
Section 14.06 the kind and amount of cash, securities or other property receivable upon such
reclassification, change, consolidation, merger, binding share exchange, combination, sale or
conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). Such supplemental indenture shall provide for
provisions and adjustments which shall be as nearly equivalent as may be practicable to the
provisions and adjustments provided for in this Article 14.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each holder of Notes, at its address appearing on the Note Register provided for in Section 2.05 of
this Indenture, within 20 calendar days after execution thereof. Failure to deliver such notice
shall not affect the legality or validity of such supplemental indenture.

In addition, any issuer of securities included in the Applicable Consideration shall execute
an amendment to the Registration Rights Agreement (to the extent any Transfer Restricted Securities
(as defined therein) remain outstanding) to make the provisions thereof apply to such securities.

The above provisions of this Section shall similarly apply to successive reclassifications,
changes, consolidations, mergers, binding share exchanges, combinations, sales and conveyances.

For purposes of determining the Exchange Value as provided in Section 14.04 the following
provisions shall apply: (i) if the Applicable Consideration includes securities for which the price
can be determined in a manner contemplated by the definition of “Last Reported Sale Price,” then
the value of such securities shall be determined in accordance with the principles set forth in the
“Last Reported Sale Price;” (ii) if the Applicable Consideration includes other property (other
than securities or cash), then the value of such property shall be the fair market value of such
property as determined by the Company’s Board of Directors in good faith; and (iii) if the
Applicable Consideration includes cash, then the value of such cash shall be the amount thereof.

If this Section 14.06 applies to any event or occurrence, Section 14.05 shall not apply.
Notwithstanding this Section 14.06, if a Public Acquirer Change of Control occurs and the Company
elects to adjust the Exchange Rate and its exchange obligation pursuant to, and in compliance with,
Section 14.07, the provisions of Section 14.07 shall apply to such Public Acquirer Change of
Control instead of this Section 14.06.

Section 14.07. Exchange After a Public Acquirer Change of Control.

(a) In the event of a Public Acquirer Change of Control, the Company may, in lieu of
increasing the Exchange Rate by Additional Shares pursuant to Section 14.01(e), elect (subject to
the satisfaction of the provisions of this Section 14.07) to adjust the Exchange Rate and the
related exchange obligation such that from and after the Effective Date of such Public Acquirer
Change of Control, holders will be entitled to exchange their Notes, in accordance with Section
14.02 hereof (subject to the satisfaction of the requirements of Section 14.01) into a number of
shares of Public Acquirer Common Stock by adjusting the Exchange Rate in effect immediately before
the Public Acquirer Change of Control by multiplying it by a fraction:

(i) the numerator of which will be (A) in the case of a share exchange, consolidation,
merger or binding share exchange, pursuant to which the Common Stock is converted into cash,
securities or other property, the average value of all cash and any other consideration (as
determined by the Company’s Board of Directors in the manner contemplated by Section 14.06)
paid or payable per share of Common Stock or (B) in the case of any other Public Acquirer
Change of Control, the average of the Last Reported Sale Prices of the Common Stock for the
five consecutive Trading Days prior to but excluding the Effective Date of such Public
Acquirer Change of Control, and

(ii) the denominator of which will be the average of the Last Reported Sale Prices of
the Public Acquirer Common Stock for the five consecutive Trading Days commencing on the
Trading Day next succeeding the Effective Date of such Public Acquirer Change of Control.

(b) In order to make the election pursuant to this Section 14.07, the Company and the issuer
of the Public Acquirer Common Stock shall execute with the Trustee a supplemental indenture (which
shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental
indenture) providing that each Note shall be exchangeable into Public Acquirer Common Stock and
execute an amendment to the Registration Rights Agreement (to the extent any Transfer Restricted
Securities (as defined therein) remain outstanding) to make the provisions thereof apply to the
Public Acquirer Common Stock. Such supplemental indenture shall provide for provisions and
adjustments which shall be as nearly equivalent as may be practicable to the provisions and
adjustments provided for in this Article 14.

(c) The Company will notify holders of its election by providing notice as set forth in
Section 14.01(c) promptly after making the election pursuant to this Section 14.07.

Section 14.08. Taxes on Shares Issued. The issue of stock certificates on exchanges of Notes
shall be made without charge to the exchanging Noteholder for any documentary, stamp or similar
issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required
to pay any such tax which may be payable in respect of any transfer involved in the issue and
delivery of stock in any name other than that of the holder of any Note exchanged, and the Company
shall not be required to issue or deliver any such stock certificate unless and until the Person or
Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

Section 14.09. Reservation of Shares, Shares to Be Fully Paid; Compliance with Governmental
Requirements; Listing of Common Stock. (a) The Issuer shall reserve and provide, free from
preemptive rights, out of its authorized but unissued shares or shares held in treasury by the
Issuer, sufficient shares of Common Stock to provide for exchange of the Notes from time to time
and shall contribute such shares to the Company for delivery to holders upon exchange of the Notes.
The Issuer further agrees that it will not engage in any transactions (including, without
limitation, making any dividends or distributions, issuing any rights or warrants, or making any
tender offer) which would require an adjustment to the Exchange Rate as provided in this Section
14.09 until the Issuer has complied with the provisions of the immediately preceding sentence.

(b) Before taking any action which would cause an adjustment increasing the Exchange Rate to
an amount that would cause the Exchange Price to be reduced below the then par value, if any, of
the shares of Common Stock issuable upon exchange of the Notes, the Issuer will take all corporate
action which may, in the opinion of its counsel, be necessary in order that the Company may validly
and legally issue shares of such Common Stock at such adjusted Exchange Rate.

(c) The Company and the Issuer covenant that all shares of Common Stock which may be issued
upon exchange of Notes shall have been duly authorized and upon issue and delivery in accordance
with the terms of this Indenture shall be validly issued, fully paid and non-assessable by the
Issuer and free from all taxes, liens and charges with respect to the issue thereof.

The Company and the Issuer covenant that, if any shares of Common Stock to be provided for the
purpose of exchange of Notes hereunder require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly issued upon exchange,
the Company and the Issuer will in good faith and as expeditiously as possible, to the extent then
permitted by the rules and interpretations of the Commission (or any successor thereto), endeavor
to secure such registration or approval, as the case may be. In connection with any transaction
referred to in Sections 14.06 or 14.07, the Company and any other Person required to issue common
stock upon exchange of a Note shall take such actions as are required so that Section 3(a)(9) or
another exemption under the Securities Act can be relied upon in connection with such exchange of
the Notes to permit such exchange without requiring registration thereof under the Securities Act
or provide for the registration of such exchange under the Securities Act.

The Issuer further covenants that, if at any time the Common Stock shall be listed on the New
York Stock Exchange, Nasdaq National Market or any other national securities exchange or automated
quotation system, the Issuer will, if permitted by the rules of such exchange or automated
quotation system, list and keep listed, so long as the Common Stock shall be so listed on such
exchange or automated quotation system, all Common Stock issuable upon exchange of the Notes;
provided that if the rules of such exchange or automated quotation system permit the Issuer to
defer the listing of such Common Stock until the first exchange of the Notes into Common Stock in
accordance with the provisions of this Indenture, the Issuer covenants to list such Common Stock
issuable upon exchange of the Notes in accordance with the requirements of such exchange or
automated quotation system at such time.

Section 14.10. Responsibility of Trustee. The Trustee and any other Exchange Agent shall not
at any time be under any duty or responsibility to the Company or any holder of Notes to determine
the Exchange Rate or whether any facts exist which may require any adjustment of the Exchange Rate,
or with respect to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture provided to be employed,
in making the same. The Trustee and any other Exchange Agent shall not be accountable with respect
to the validity or value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at any time be issued or delivered upon the exchange of any Note;
and the Trustee and any other Exchange Agent make no representations with respect thereto. Neither
the Trustee nor any Exchange Agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of Common Stock or stock certificates or other securities or
property or cash upon the surrender of any Note for the purpose of exchange or to comply with any
of the duties, responsibilities or covenants of the Company contained in this Article 14. Without
limiting the generality of the foregoing, neither the Trustee nor any Exchange Agent shall be under
any responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 14.06 relating either to the kind or amount of shares of
stock or securities or property (including cash) receivable by Noteholders upon the exchange of
their Notes after any event referred to in such Section 14.06 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence
of the correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate (which the Company shall be obligated to file with the Trustee prior to the execution
of any such supplemental indenture) with respect thereto.

Section 14.11. Notice to Holders Prior to Certain Actions. In case:

(a) The Issuer shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Exchange Rate pursuant to Section 14.05; or

(b) The Issuer shall authorize the granting to the holders of all or substantially all of its
Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other
rights or warrants; or

(c) of any reclassification or reorganization of the Common Stock of the Issuer (other than a
subdivision or combination of its outstanding Common Stock, or a change in par value, or from par
value to no par value, or from no par value to par value), or of any consolidation or merger to
which the Issuer is a party and for which approval of any stockholders of the Issuer is required,
or of the sale or transfer of all or substantially all of the assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Issuer or
the Company;

the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at
his address appearing on the Note Register provided for in Section 2.05 of this Indenture, as
promptly as possible but in any event at least ten (10) calendar days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to such dividend,
distribution or rights are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding
up. Failure to give such notice, or any defect therein, shall not affect the legality or validity
of such dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

Section 14.12. Stockholder Rights Plan. To the extent that the Issuer has a rights plan in
effect upon exchange of the Notes, the Noteholder will receive, in addition to the Common Stock, if
any, the rights under the rights plan, unless prior to any exchange, the rights have separated from
the Common Stock, in which case the Exchange Rate will be adjusted at the time of separation as if
the Issuer distributed to all holders of Common Stock, shares of the Issuer’s capital stock,
evidences of indebtedness or assets as described in Section 14.04(c) above, subject to readjustment
in the event of the expiration, termination or redemption of such rights. In lieu of any such
adjustment, the Issuer may amend such applicable stockholder rights agreement to provide that upon
exchange of the Notes the holders will receive, in addition to the Common Stock issuable upon such
exchange, the rights which would have attached to such Common Stock if the rights had not become
separated from the Common Stock under such applicable stockholder rights agreement.

ARTICLE 15

Guarantees

Section 15.01. Guarantees. (a) Subject to the provisions of this Article 15, the Issuer and
the Subsidiary Guarantors hereby irrevocably and unconditionally guarantee, jointly and severally,
on a senior basis to each holder and to the Trustee and its successors and assigns (i) the full and
punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise,
of all obligations of the Company under this Indenture (including obligations to the Trustee) and
the Notes, whether for payment of principal of or interest on the Notes, delivery of the Settlement
Amount and all other monetary obligations of the Company under this Indenture and the Notes and
(ii) the full and punctual performance within applicable grace periods of all other obligations of
the Company whether for fees, expenses, indemnification or otherwise under this Indenture and the
Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).
Subject to Section 15.02, the Issuer and the Subsidiary Guarantors further agree that the
Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further
assent from either the Issuer or the Subsidiary Guarantors, and that the Issuer and the Subsidiary
Guarantors shall remain bound under this Article 15 notwithstanding any extension or renewal of any
Guaranteed Obligation.

(b) To the extent permitted by law, the Issuer and the Subsidiary Guarantors waive
presentation to, demand of payment from and protest to the Company of any of the Guaranteed
Obligations and also waive notice of protest for nonpayment. The Issuer and the Subsidiary
Guarantors waive notice of any default under the Notes or the Guaranteed Obligations. The
obligations of the Issuer and the Subsidiary Guarantors hereunder shall not be affected by (i) the
failure of any holder or the Trustee to assert any claim or demand or to enforce any right or
remedy against the Company or any other Person under this Indenture, the Notes or any other
agreement or otherwise; (ii) any extension or renewal of any thereof; (iii) any rescission, waiver,
amendment or modification of any of the terms or provisions of this Indenture, the Notes or any
other agreement; (iv) the release of any security held by any holder or the Trustee for the
Guaranteed Obligations or any of them; (v) the failure of any holder or the Trustee to exercise any
right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in
the ownership of the Issuer or the Subsidiary Guarantors, except as provided in Section 15.02(b).

(c) The Issuer and each Subsidiary Guarantor agrees that its Guarantee constitutes a guarantee
of payment, performance and compliance when due (and not a guarantee of collection) and waives any
right to require that any resort be had by any holder or the Trustee to any security held for
payment of the Guaranteed Obligations.

(d) Except as expressly set forth in Section 15.02, the obligations of the Issuer and the
Subsidiary Guarantors hereunder shall not be subject to any reduction, limitation, impairment or
termination for any reason, including any claim of waiver, release, surrender, alteration or
compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or
termination whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of the Issuer and the Subsidiary Guarantors herein shall not be discharged or impaired
or otherwise affected by the failure of any holder or the Trustee to assert any claim or demand or
to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Guaranteed Obligations, or by any other act or thing or omission or delay to do
any other act or thing which may or might in any manner or to any extent vary the risk of the
Issuer or the Subsidiary Guarantors or would otherwise operate as a discharge of the Issuer or the
Subsidiary Guarantors as a matter of law or equity.

(e) The Issuer and each Subsidiary Guarantors agree that its respective Guarantee shall remain
in full force and effect until payment in full of all the Guaranteed Obligations. The Issuer and
each Subsidiary Guarantors further agrees that its Guarantee shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or
interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any holder or
the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

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

(g) The Issuer and each Subsidiary Guarantors agree that it shall not be entitled to any right
of subrogation in relation to the holders in respect of any Guaranteed Obligations guaranteed
hereby until payment in full of all Guaranteed Obligations. The Issuer and each Subsidiary
Guarantors further agree that, as between it, on the one hand, and the holders and the Trustee, on
the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated
as provided in Article 6 for the purposes of its Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed
hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as
provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith
become due and payable by the Issuer and the Subsidiary Guarantors or the Company for the purposes
of this Section 15.01.

(h) The Issuer and the Subsidiary Guarantors also agree to pay any and all costs and expenses
(including reasonable attorneys’ fees and expenses) incurred by the Trustee or any holder in
enforcing any rights under this Section 15.01.

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

Section 15.02. Limitation on Liability. (a) Any other term or provision of this Indenture to
the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed
hereunder by each Subsidiary Guarantors shall not exceed the maximum amount that can be hereby
guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantors, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.

(b) A Subsidiary Guarantee shall terminate and be of no further force in effect and the
Subsidiary Guarantors shall be deemed to be released from all obligations under this Article 15
(without any further action by the Trustee or the holders) upon (i) the sale or other disposition
of all or substantially all of the assets of the Subsidiary Guarantors (including by way of any
merger or consolidation) or (ii) the sale or other disposition of all of the capital stock of a
Subsidiary Guarantor, in each case, other than the sale or other disposition to the Issuer or a
Subsidiary of the Issuer. At the request of the Company, the Trustee shall execute and deliver an
appropriate instrument evidencing such release (in the form provided by the Company).

Section 15.03. Successors and Assigns. This Article 15 shall be binding upon the Issuer and
any Subsidiary Guarantor and their successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the holders and, in the event of any transfer or
assignment of rights by any holder or the Trustee, the rights and privileges conferred upon that
party in this Indenture and in the Notes shall automatically extend to and be vested in such
transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 15.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or
the holders in exercising any right, power or privilege under this Article 15 shall operate as a
waiver thereof, nor shall a single or partial exercise thereof preclude any other or further
exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the
holders herein expressly specified are cumulative and not exclusive of any other rights, remedies
or benefits which either may have under this Article 15 at law, in equity, by statute or otherwise.

Section 15.05. Modification. No modification, amendment or waiver of any provision of this
Article 15, nor the consent to any departure by the Issuer or any Subsidiary Guarantor therefrom,
shall in any event be effective unless the same shall be in writing and signed by the Trustee, and
then such waiver or consent shall be effective only in the specific instance and for the purpose
for which given. No notice to or demand on the Issuer or any Subsidiary Guarantor in any case shall
entitle the Issuer or any Subsidiary Guarantor to any other or further notice or demand in the
same, similar or other circumstances.

Section 15.06. Execution of Supplemental Indenture for Future Guarantors. Each Person which is
required to become a Guarantor pursuant to Section 4.10, shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Exhibit C hereto pursuant to which such Subsidiary
or other Person shall become a Guarantor under this Article 15 and shall guarantee the Guaranteed
Obligations. Concurrently with the execution and delivery of such supplemental indenture, the
Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the
effect that such supplemental indenture has been duly authorized, executed and delivered by such
Subsidiary or other Person and that, subject to the application of bankruptcy, insolvency,
moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights
generally and to the principles of equity, whether considered in a proceeding at law or in equity,
the Guarantee of such Subsidiary Guarantor is a legal, valid and binding obligation of such
Subsidiary Guarantor, enforceable against such Subsidiary Guarantor in accordance with its terms
and/or to such other matters as the Trustee may reasonably request.

Section 16.08. Trust Indenture Act. This Indenture is hereby made subject to, and shall be

require this Indenture or the Trustee to be qualified under the Trust Indenture Act prior to the
time such qualification is in fact required under the terms of the Trust Indenture Act, nor shall
it constitute any admission or acknowledgment by any party to the Indenture that any such
qualification is required prior to the time such qualification is in fact required under the terms
of the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in an indenture qualified under the Trust
Indenture Act, such required provision shall control.

Section 16.09. No Security Interest Created. Except as provided in Section 7.06, nothing in
this Indenture or in the Notes, expressed or implied, shall be construed to constitute a security
interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and

delivery of Notes in connection with the original issuance thereof and transfers and exchanges of
Notes hereunder, including under Sections 2.04, 2.05, 2.06, 2.07, 3.02 and 3.06, as fully to all
intents and purposes as though the authenticating agent had been expressly authorized by this
Indenture and those Sections to authenticate and deliver Notes. For all purposes of this
Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to
be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such
authenticating agent shall at all times be a Person eligible to serve as trustee hereunder pursuant
to Section 7.09.

Any corporation into which any authenticating agent may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, consolidation or conversion
to which any authenticating agent shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of any authenticating agent, shall be the successor
of the authenticating agent hereunder, if such successor corporation is otherwise eligible under
this Section 16.11, without the execution or filing of any paper or any further act on the part of
the parties hereto or the authenticating agent or such successor corporation.

Any authenticating agent may at any time resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Company.
Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee shall either
promptly appoint a successor authenticating agent or itself assume the duties and obligations of
the former authenticating agent under this Indenture and, upon such appointment of a successor
authenticating agent, if made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of a successor
authenticating agent to all holders of Notes as the names and addresses of such holders appear on
the Note Register.

The Company agrees to pay to the authenticating agent from time to time such reasonable
compensation for its services as shall be agreed upon in writing between the Company and the
authenticating agent.

The provisions of Sections 7.02, 7.03, 7.04 and 8.03 and this Section 16.11 shall be
applicable to any authenticating agent.

Section 16.12. Execution in Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original, but such counterparts shall together constitute
but one and the same instrument.

Section 16.13. Severability. In case any provision in this Indenture or in the Notes shall be
invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

The Bank of New York Trust Company, N.A. hereby accepts the trusts in this Indenture declared
and provided, upon the terms and conditions herein above set forth.

Section 16.14. Force Majeure. In no event shall the Trustee be responsible or liable for any
failure or delay in the performance of its obligations hereunder arising out of or caused by,
directly or indirectly, forces beyond its control, including, without limitation, strikes, work
stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural
catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications
or computer (software and hardware) services; it being understood that the Trustee shall use
reasonable efforts which are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

Company, N.A., as trustee (herein called the “Trustee”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Issuer, the
Subsidiary Guarantors and the holders of the Notes. The Company may issue an unlimited Principal
Amount of Additional Notes as provided in the Indenture having identical terms and conditions as
the Notes. Any Additional Notes will be part of the same issue as the Notes and will vote on all
matters with the holders of the Notes.

The payment by the Company of the principal of and interest on the Notes is fully and
unconditionally guaranteed by the Issuer and the Subsidiary Guarantors on a senior basis pursuant
to the terms of the Indenture.

In case an Event of Default shall have occurred and be continuing, the Principal Amount of and
accrued Interest on all Notes may be declared by either the Trustee or the holders of not less than
25% in aggregate Principal Amount of the Notes then outstanding, and upon said declaration shall
become, or may as provided in the Indenture automatically become, due and payable, in the manner,
with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Company, the Issuer, the Subsidiary
Guarantors and the Trustee, with the consent of the holders of at least a majority in aggregate
Principal Amount of the Notes at the time outstanding, to execute supplemental indentures adding
any provisions to or changing in any manner or eliminating any of the provisions of the Indenture
or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes,
subject to the exceptions set forth in Section 10.02 of the Indenture. Subject to the provisions
of the Indenture, the holders of a majority in aggregate Principal Amount of the Notes at the time
outstanding may on behalf of the holders of all of the Notes waive any past default or Event of
Default under the Indenture and its consequences, subject to the exceptions set forth in the
Indenture. Any such consent or waiver by the holder of this Note (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such holder and upon all future holders and
owners of this Note and any Notes which may be issued in exchange or substitution hereof,
irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, the Issuer or the Subsidiary Guarantors, which are
absolute and unconditional, to pay the Principal Amount of and Interest on this Note at the place,
at the respective times, at the rate and in the coin or currency herein prescribed.

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

The Notes are issuable in fully registered form, without interest coupons, in denominations of
$1,000 Principal Amount and any multiple of $1,000. At the office or agency of the Company
referred to on the face hereof, and in the manner and subject to the limitations provided in the
Indenture, without payment of any service charge but with payment of a sum sufficient to cover any
tax, assessment or other governmental charge that may be imposed in connection with any
registration or exchange of Notes, Notes may be exchanged for a like aggregate Principal Amount of
Notes of any other authorized denominations.

At any time on or after December 15, 2010, the Notes may be redeemed at the option of the
Company, in whole or in part, in cash upon mailing a notice of such redemption not less than 35
calendar days but not more than 60 calendar days before the Redemption Date to the holders of Notes
at their last registered addresses, all as provided in the Indenture, at a Redemption Price equal
to 100% of the Principal Amount of notes being redeemed plus accrued and unpaid Interest to, but
not including, the Redemption Date; provided that if the applicable Redemption Date is after a
Regular Record Date and on or prior to the corresponding Interest Payment Date, Interest will be
paid on the Redemption Date to the holder on the applicable record date. In no event will the
Notes be redeemable at the option of the Company before December 15, 2010. The Company may not
give notice of any redemption of the Notes if a default in the payment of Interest on the Notes has
occurred and is continuing.

The Notes are not subject to redemption through the operation of any sinking fund.

If a Fundamental Change occurs at any time prior to maturity of the Notes, the holders will
have the right to require the Company to repurchase all or any portion of the Notes on a
Fundamental Change Repurchase Date specified by the Company, which shall be no later than 30
Business Days after notice thereof, in integral multiples of $1,000 Principal Amount at a
Fundamental Change Repurchase Price equal to 100% of the Principal Amount thereof, together with
accrued Interest to, but not including, the Fundamental Change Repurchase Date; provided that if
the applicable Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to
the corresponding Interest Payment Date, the Interest payable on such Interest Payment Date shall
be paid on such Interest Payment Date to the holders of record of such Notes on the applicable
record date instead of the holders surrendering such Notes for repurchase on such date. The Company
shall mail to all holders of record of the Notes a notice of the occurrence of a Fundamental Change
and of the repurchase right arising as a result thereof on or before the 30th calendar day after
the occurrence of such Fundamental Change. To exercise such right, a holder must deliver to the
Paying Agent such Notes with the form entitled “Form of Fundamental Change Repurchase Election” on
the reverse thereof duly completed, together with such Notes, duly endorsed for transfer (or if
such Notes are Global Notes, book-entry transfer of such Notes) at any time prior to 5:00 p.m., New
York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date.

Subject to the terms and conditions of the Indenture, the holders will have the right to
require the Company to repurchase all or any portion of the Notes on December 15, 2010, December
15, 2015 and December 15, 2020 in integral multiples of $1,000 Principal Amount at a Company
Repurchase Price of 100% of the Principal Amount, plus any accrued and unpaid Interest on such Note
to, but not including, the Company Repurchase Date; provided that the Interest payable on the
applicable Company Repurchase Date shall be paid on such Interest Payment Date to the holders of
record of such Notes on the applicable record date instead of the holders surrendering such Notes
for repurchase on such date. To exercise such right, a holder must deliver to the Paying Agent
such Notes with the form entitled “Form of Company Repurchase Election” on the reverse thereof duly
completed, together with such Notes, duly endorsed for transfer (or if such Notes are Global Notes,
book-entry transfer of such Notes) at any time from 9:00 a.m., New York City time, on the date that
is 20 Business Days prior to such Company Repurchase Date until 5:00 p.m., New York City time, on
the Business Day immediately preceding the Company Repurchase Date.

The Company Repurchase Price to be paid on any of December 15, 2010, December 15, 2015 and
December 15, 2020 and the Fundamental Change Repurchase Price to be paid on any Fundamental Change
Repurchase Date shall be paid in cash, subject to the terms and conditions of the Indenture.

Holders have the right to withdraw any Repurchase Election by delivering to the Paying Agent a
written notice of withdrawal up to 5:00 p.m., New York City time, on the Business Day immediately
preceding the Repurchase Date, all as provided in the Indenture.

If on the Repurchase Date the Trustee or other Paying Agent appointed by the Company (or, if
the Company or the Issuer is acting as the Paying Agent, the Company or the Issuer) holds money
sufficient to pay the aggregate Repurchase Price of all the Notes or portions thereof that are to
be repurchased plus accrued and unpaid Interest, if any, to, but not including, the Repurchase
Date, if applicable, then, on such Repurchase Date (i) such Notes will cease to be outstanding,
(ii) Interest on such Notes will cease to accrue (in the case of clauses (i) and (ii), whether or
not book-entry transfer of the Notes has been made or the Notes have been delivered to the Paying
Agent, as the case may be), and (iii) all other rights of the holders of such Notes will terminate
(other than the right to receive the Repurchase Price plus accrued and unpaid Interest, if any, to,
but not including, the Repurchase Date, if applicable upon book-entry transfer or delivery of the
Notes, as the case may be).

Subject to the occurrence of certain events and in compliance with the provisions of the
Indenture, on or prior to the Trading Day preceding the Stated Maturity, the holder hereof has the
right, at its option, to exchange, in accordance with the terms and provisions of the Indenture,
each $1,000 principal amount of this Note into 49.8473 shares of Common Stock (an Exchange Price of
approximately $20.06 per share) as such shares shall be constituted at the date of exchange and
subject to adjustment from time to time as provided in the Indenture, upon surrender of this Note
(in certificated form) with the form entitled “Form of Exchange Notice” on the reverse hereof duly
completed and manually signed, to the Company at the office or agency of the Company maintained for
that purpose in accordance with the terms of the Indenture, or at the option of such holder, the
Corporate Trust Office together with any funds required pursuant to the terms of the Indenture,
and, unless the shares issuable on exchange are to be issued in the same name as this Note, duly
endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly
executed by, the holder or by his duly authorized attorney. The Company will notify the holder
thereof of any event triggering the right to exchange the Notes as specified above in accordance
with the Indenture. In order to exercise the exchange right with respect to any interest in a
Global Note, the holder must complete and deliver the appropriate instruction form pursuant to the
Depositary’s book-entry exchange program, together with any funds required pursuant to the terms of
the Indenture, deliver by book-entry delivery an interest in such Global Note, furnish appropriate
endorsements and transfer documents if required pursuant to the terms of the Indenture. Upon
exchange, the Company will deliver cash equal to the lesser of the aggregate principal amount of
Notes being exchanged and the Exchange Value, and shares of Common Stock in respect of the
remainder, if any, of the Exchange Value as provided in the Indenture.

If the Issuer (i) is a party to a consolidation, merger, statutory share exchange or
combination, (ii) reclassifies the Common Stock, or (iii) sells or conveys its properties and
assets substantially as an entirety to any Person, the right to exchange a Security into shares of
Common Stock may be changed into a right to exchange it into the kind or amount of cash, securities
or other property receivable upon such event, in each case in accordance with the Indenture.

In addition, following certain corporate transactions as set forth in Section 14.01(b) of the
Indenture that occur prior to December 15, 2010 and that also constitute a Fundamental Change, the
Exchange Rate will be increased by the number of Additional Shares of Common Stock in certain
circumstances as provided in the Indenture. In certain circumstances involving a Public Acquirer
Change of Control, the Company may elect, in lieu of increasing the Exchange Rate by the number of
Additional Shares of Common Stock, to provide for the exchange of the Notes into shares of the
Public Acquirer Common Stock as set forth in Section 14.07 of the Indenture.

No adjustment in respect of Interest on any Note exchanged (other than the payment of
Additional Interest, if any) or dividends on any shares issued upon exchange of such Note will be
made upon any exchange except as set forth in the next sentence. If this Note (or portion hereof)
is surrendered for exchange during the period from 5:00 p.m., New York City time, on any record
date for the payment of Interest to 9:00 a.m., New York City time, on the immediately following
Interest Payment Date, this Note (or portion hereof being exchanged) must be accompanied by
payment, in immediately available funds or other funds acceptable to the Company, of an amount
equal to the Interest otherwise payable on such Interest Payment Date on the Principal Amount being
exchanged; provided that no such payment shall be required (1) if the Company has specified a
Redemption Date that is after a record date and on or prior to the corresponding Interest Payment
Date, (2) if the Company has specified a Fundamental Change Repurchase Date that is after a record
date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue
Interest, if any overdue Interest exists at the time of exchange with respect to such Note.

No fractional shares will be issued upon any exchange, but an adjustment and payment in cash
will be made, as provided in the Indenture, in respect of any fraction of a share which would
otherwise be issuable upon the surrender of any Note or Notes for exchange.

A Note in respect of which a holder is exercising its right to require repurchase upon a
Fundamental Change or repurchase on a Repurchase Date may be exchanged only if such holder
withdraws its election to exercise such right in accordance with the terms of the Indenture.

Upon due presentment for registration of transfer of this Note at the office or agency of the
Company maintained for that purpose in accordance with the terms of the Indenture, a new Note or
Notes of authorized denominations for an equal aggregate Principal Amount will be issued to the
transferee in exchange thereof, subject to the limitations provided in the Indenture, without
charge except for any tax, assessment or other governmental charge imposed in connection therewith.

The Company, the Issuer, the Subsidiary Guarantors, the Trustee, any authenticating agent, any
Paying Agent, any Exchange Agent and any Note Registrar may deem and treat the registered holder
hereof as the absolute owner of this Note (whether or not this Note shall be overdue and
notwithstanding any notation of ownership or other writing hereon made by anyone other than the
Company or any Note Registrar) for the purpose of receiving payment hereof, or on account hereof,
for the exchange hereof and for all other purposes, and neither the Company nor the Trustee nor any
other authenticating agent nor any Paying Agent nor other Exchange Agent nor any Note Registrar
shall be affected by any notice to the contrary. All payments made to or upon the order of such
registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for
monies payable on this Note.

No recourse for the payment of the Principal Amount of or Interest on any Note, or for any
claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company, the Issuer or the Subsidiary Guarantors in the Indenture or
in any supplemental indenture or in any Note, or of the Issuer and the Subsidiary Guarantors under
the Guarantees or because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such,
past, present or future, of the Company, the Issuer or the Subsidiary Guarantors or of any
successor corporation, either directly or through the Company, the Issuer or the Subsidiary
Guarantors or any successor corporation, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood
that all such liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of the Indenture and the issue of the Notes.

Terms used in this Note and defined in the Indenture are used herein as therein defined.
