such terms in the Trust Indenture Act and in the Securities Act as in force at the date of the
execution of this Indenture. The words “herein”, “hereof”, “hereunder” and words of similar import
refer to this Indenture as a whole and not to any particular Article, Section or other Subdivision.
The terms defined in this Article include the plural as well as the singular.

     “1.625% Convertible Notes” means the Senior Subordinated Notes due 2034 issued by the Company
and guaranteed by the Guarantor, which bear interest at 1.625% per annum until March 15, 2009.

     “Agent Members” has the meaning specified in Section 2.05(b).

     “Affiliate” of any specified Person means any other Person directly or indirectly controlling

purposes of this definition, “control”, when used with respect to any specified Person means the
power to direct or cause the direction of the management and policies of such Person, directly or
indirectly, whether through the ownership of voting securities, by contract or otherwise, and the
terms “controlling” and “controlled” have meanings correlative to the foregoing.

     “beneficial holder” shall be determined in accordance with Rules 13d-3 and 13d-5 promulgated
by the Commission under the Exchange Act, or any successor provision thereto, except that a Person
shall be deemed to have “beneficial ownership” of all shares that such Person has the right to
acquire, whether such right is exercisable immediately or only after the passage of time.

2

 

     “Bid Solicitation Agent” means such Person (other than any Affiliate of the Company) as the
Company may designate as Bid Solicitation Agent from time to time, and shall initially mean the

such Board duly authorized to act for it hereunder.

     “Board Resolution” means a copy of one or more resolutions, certified by the Secretary or an

Directors of the Company and to be in full force and effect on the date of such certification,

     “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday
nor a day on which commercial banks are authorized or required by law, regulation or executive
order to close in The City of New York.

     “Capital Stock” of any Person means any and all shares (including ordinary shares or American
Depositary Shares), interests, participations or other equivalents, however designated of corporate
stock or other equity participations, including partnership interests, whether general or limited,
of such Person and any rights (other than debt securities convertible or exchangeable into an
equity interest), warrants or options to acquire an equity interest in such Person.

     “Cash Settlement Notice Period” means, in respect of any New Note tendered for conversion, the
five Business Day period following receipt of a Noteholder’s Notice of Conversion.

     “Commission” means the Securities and Exchange Commission, as from time to time constituted
under the Exchange Act, or, if at any time after the execution of this Indenture such Commission is
not existing and performing the duties now assigned to it under the Trust Indenture Act, then the
body performing such duties at such time.

     “Common Stock” means any stock of any class of the Company which has no preference in respect
of dividends or of amounts payable in the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Company and which is not subject to redemption by the Company.
Subject to the provisions of Section 14.08, however, shares issuable on conversion of New Notes
shall include only shares of the class designated as common stock of the Company at the date of
this Indenture (namely, the Common Stock, par value $0.01 per share) or shares of any class or
classes resulting from any reclassification or reclassifications thereof and which have no
preference in respect of dividends or of amounts payable in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Company and which are not subject to
redemption by the Company; provided that if at any time there shall

3

 

be more than one such resulting
class, the shares of each such class then so issuable on conversion shall be substantially in the
proportion which the total number of shares of such class resulting from all such reclassifications
bears to the total number of shares of all such classes resulting from all such reclassifications.
Following the event of a merger, consolidation or other similar transaction involving the Company
that is otherwise permitted hereunder in which

     Any Interest on any New Note which is payable, but is not punctually paid or duly provided
for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the Noteholder on the relevant Regular Record Date by virtue of his having been such
Noteholder, and such Defaulted Interest shall be paid by the Company, 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 New Notes (or their respective Predecessor Notes) are registered at the close of business
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 New Note and the date of the proposed payment (which
shall be not less than twenty-five (25) 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 (15) days and not less than
ten (10) days prior to the date of the proposed payment, and not less than ten (10) days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify
the

16

 

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 (10) 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 New Notes (or their
respective Predecessor Notes) are registered at the close of business 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 New 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 New Notes. The New 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 or any Vice President (whether or not designated by a number or
numbers, or word or words, added before or after the title “Vice President”). Only such New Notes
as shall bear thereon a certificate of authentication substantially in the form set forth on the
form of New Note attached as Exhibit A hereto, manually executed by the Trustee (or an
authenticating agent appointed by the Trustee as provided by Section 18.13), 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 New Note executed by the Company shall be
conclusive evidence that the New 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 New Notes shall cease to
be such officer before the New Notes so signed shall have
been authenticated and delivered by the Trustee, or disposed of by the Company, such New Notes
nevertheless may be authenticated and delivered or disposed of as though the person who signed such
New Notes had not ceased to be such officer of the Company, and any New Note may be signed on
behalf of the Company by such persons as, at the actual date of the execution of such New 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.

17

 

     Section 2.05. Exchange and Registration of Transfer of New Notes; Restrictions on Transfer.

     (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register
maintained in such office and in any other office or agency of the Company designated pursuant to
Section 4.02 being herein sometimes collectively referred to as the “Note Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of New Notes and of transfers of New Notes. The Note Register shall be in written
form or in any form capable of being converted into written form within a reasonably prompt period
of time. The Trustee is hereby appointed “Note Registrar” for the purpose of registering New Notes
and transfers of New Notes as herein provided. The Company may appoint one or more co-registrars
in accordance with Section 4.02.

     Upon surrender for registration of transfer of any New Note to the Note Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth in this Section
2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more New Notes of any authorized denominations and of
a like aggregate principal amount and bearing such restrictive legends as may be required by this
Indenture.

     New Notes may be exchanged for other New Notes of any authorized denominations and of a like
aggregate principal amount, upon surrender of the New Notes to be exchanged at any such office or
agency maintained by the Company pursuant to Section 4.02. Whenever any New Notes are so
surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the New Notes which the Noteholder making the exchange is entitled to receive bearing
registration numbers not contemporaneously outstanding.

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

     All New Notes presented or surrendered for registration of transfer or for exchange,
redemption, repurchase or conversion shall (if so required by the Company or the Note Registrar) be
duly endorsed, or be accompanied by a
written instrument or instruments of transfer in form satisfactory to the Company, duly
executed by the Noteholder thereof or his attorney duly authorized in writing.

     No service charge shall be made to any Noteholder for any registration, transfer or exchange
of New Notes, but the Company may require payment by the Noteholder of a sum sufficient to cover
any tax, assessment or other governmental

18

 

charge that may be imposed in connection with any
registration of transfer or exchange of New Notes.

     Neither the Company nor the Trustee nor any Note Registrar shall be required to exchange or
register a transfer of (a) any New Notes for a period of fifteen (15) days next preceding any
selection of New Notes to be redeemed, (b) any New Notes or portions thereof called for redemption
pursuant to Section 3.01 (c) any New Notes or portions thereof surrendered for conversion pursuant
to Article 14, (d) any New Notes or portions thereof tendered for repurchase (and not withdrawn)
pursuant to Section 3.05 or (e) any New Notes or portions thereof tendered for repurchase (and not
withdrawn) pursuant to Section 3.06.

     (b) The following provisions shall apply only to Global Notes:

     (i) Each Global Note authenticated under this Indenture shall be registered in the
name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee
thereof or Custodian therefor, and each such Global Note shall constitute a single Note
for all purposes of this Indenture.

     (ii) Notwithstanding any other provision in this Indenture, no Global Note may be
exchanged in whole or in part for New Notes registered, and no transfer of a Global Note
in whole or in part may be registered, in the name of any Person other than the Depositary
or a nominee thereof unless (A) the Depositary (i) has notified the Company that it is
unwilling or unable to continue as Depositary for such Global Note and a successor
depositary has not been appointed by the Company within ninety (90) days or (ii) has
ceased to be a clearing agency registered under the Exchange Act, (B) an Event of Default
has occurred and is continuing, (C) the Company, in its sole discretion, notifies the
Trustee in writing that it no longer wishes to have all the New Notes represented by
Global Notes or (D) any beneficial holder reasonably requests such exchange on terms
acceptable to the Company, the Trustee and the Depositary, which in the case of the
Trustee may include, in the Trustee’s sole discretion, among other things, the requirement
that (i) the Trustee and any Note Registrar receive (a) from the Company or the
Depositary, a written order, in either case requesting such exchange, and an Opinion of
Counsel (which upon receipt thereof the Trustee and such Note Registrar shall be fully
protected in relying) to the effect that (x) all securities laws in connection with such
exchange have been complied with and (y) such exchange is otherwise authorized or
permitted by this
Indenture; and (b) from such beneficial holder (x) an affidavit as to its beneficial
ownership interest in such Global Note and/or (y) an indemnity, reasonably satisfactory to
the Trustee and such Note Registrar, against any loss, liability or expense to the Trustee
and such Note Registrar to the

19

 

extent that the Trustee or Note Registrar acts upon such
order, affidavit and/or indemnity; and (ii) such exchange can be accomplished in a manner
that is practicable and not inconsistent with the rules of any applicable Depositary or
securities exchange upon which the New Notes may be listed for trading. Any Global Note
exchanged pursuant to clause (A) or (B) above shall be so exchanged in whole and not in
part and any Global Note exchanged pursuant to clause (C) or (D) above may be exchanged in
whole or from time to time in part as directed by the Company. Any New Note issued in
exchange for a Global Note or any portion thereof shall be a Global Note; provided that
any such New Note so issued that is registered in the name of a Person other than the
Depositary or a nominee thereof shall not be a Global Note.

     (iii) New Notes issued in exchange for a Global Note or any portion thereof pursuant
to clause (ii) above shall be issued in definitive, fully registered form, without
interest coupons, shall have an aggregate principal amount equal to that of such Global
Note or portion thereof to be so exchanged, shall be registered in such names and be in
such authorized denominations as the Depositary shall designate and shall bear any legends
required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the
Depositary to the Trustee, as Note Registrar.

     With regard to any Global Note to be 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 New 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 New 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 Trustee and any agent of the Company or the
Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing

20

 

herein shall prevent the Company, the Trustee or any agent of the Company 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 New Note.

     (vi) At such time as all interests in a Global Note have been redeemed, repurchased,
converted, canceled or exchanged for New 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, converted, canceled or exchanged for New 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.

     Section 2.06. Mutilated, Destroyed, Lost or Stolen New Notes. In case any New 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 New Note, bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated New Note, or in lieu
of and in substitution for the New Note so destroyed, lost or stolen. In every case, the applicant
for a substituted New Note shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them
harmless for any loss, 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 New 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 New Note and make
available for delivery such New Note.
Upon the issuance of any substituted New 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 New Note which
has matured or is

21

 

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 converted into Common Stock shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute New
Note, pay or authorize the payment of or convert or authorize the conversion of the same (without
surrender thereof except in the case of a mutilated New Note), as the case may be, if the applicant
for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to
such authenticating agent such security or indemnity as may be required by them to save each of
them harmless from any loss, 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 Conversion Agent evidence to their
satisfaction of the destruction, loss or theft of such New Note and of the ownership thereof.

     Every substitute New Note issued pursuant to the provisions of this Section 2.06 by virtue of
the fact that any New Note is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen New 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 New Notes duly
issued hereunder. To the extent permitted by law, all New 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 New 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 New Notes. Pending the preparation of New 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 New Notes
(printed or lithographed). Temporary New Notes shall be issuable in any authorized denomination,
and substantially in the form of the New Notes in certificated form, but with such omissions,
insertions and variations as may be appropriate for temporary New Notes, all as may be determined
by the Company. Every such temporary New 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 New Notes in certificated form.
Without unreasonable delay, the Company will execute and deliver to the Trustee or such
authenticating agent New Notes in certificated form and thereupon any or all temporary New Notes
may be surrendered in exchange therefor, at each office

22

 

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 New Notes an equal aggregate principal amount
of New 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 New Notes shall in all respects
be entitled to the same benefits and subject to the same limitations under this Indenture as New
Notes in certificated form authenticated and delivered hereunder.

     Section 2.08. Cancellation of New Notes. All New Notes surrendered for the purpose of
payment, redemption, repurchase, conversion, exchange or registration of transfer shall, if
surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion 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 New 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
New Notes in accordance with its customary procedures. If the Company shall acquire any of the New
Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the
Indebtedness represented by such New Notes unless and until the same are delivered to the Trustee
for cancellation.

     Section 2.09. CUSIP Numbers. The Company in issuing the New 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 New 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 New 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 of any change in the “CUSIP” and/or similar numbers.

ARTICLE 3

Redemption and Repurchase of New Notes

     Section 3.01. Company’s Right to Redeem. Prior to July 15, 2011, the New Notes will not be
redeemable at the Company’s option. At any time on or after July 15, 2011 and prior to Stated
Maturity, the Company, at its option, may redeem the New Notes, in whole or in part, in accordance
with the provisions of Section 3.02 and Section 3.03 on the Redemption Date (as defined below) for
a redemption price (the “Redemption Price”) in cash equal to 100%
of the principal amount of the New Notes to be redeemed together with accrued and

23

 

unpaid Interest on the New Notes redeemed to but excluding the Redemption Date.

     If the Redemption Date is an Interest Payment Date, Interest shall be paid on such Interest
Payment Date to the record holder on the relevant Record Date.

     Section 3.02. Notice of Optional Redemption; Selection of New 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 New Notes pursuant to Section 3.01, it shall fix a date for redemption (the
“Redemption Date”) and it or, at the written request of the Company received by the Trustee not
fewer than thirty (30) days prior (or such shorter period of time as may be acceptable to the
Trustee) to the Redemption Date, the Trustee in the name of and at the expense of the Company,
shall mail or cause to be mailed a notice of such redemption (a “Redemption Notice”) not fewer than
thirty (30) nor more than sixty (60) days prior to the Redemption Date to each Noteholder to be
redeemed 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
Noteholder designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other New Note.

     (b) Each such Redemption Notice shall specify the aggregate principal amount of New Notes to
be redeemed, the CUSIP, ISIN or similar number or numbers of the New Notes being redeemed, the
Redemption Date (which shall be a Business Day), the Redemption Price at which New Notes are to be
redeemed, the place or places of payment, that payment will be made upon presentation and surrender
of such New Notes, 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. The Redemption Notice shall also state the current Conversion Rate and the
date on which the right to convert such New Notes or portions thereof into Common Stock pursuant to
Section 14.01(a)(ii) shall expire. The Redemption Notice shall also specify, with respect to any
such conversions of New Notes, whether the Company elects to satisfy its Conversion Obligation
entirely in cash or in shares of Common Stock or, if the Company has made the irrevocable election
described below in Section 14.03(d), whether it elects to satisfy the portion of the Daily
Conversion Value in excess of $62.50 in cash or in shares of Common Stock. If fewer than all the
New Notes are to be redeemed, the Redemption Notice shall identify the New Notes to be redeemed
(including CUSIP, ISIN or similar numbers, if any). In case any New Note is to be
redeemed in part only, the Redemption Notice shall state the

24

 

portion of the principal amount
thereof to be redeemed and shall state that, on and after the Redemption Date, upon surrender of
such New Note, a 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 Trustee or with one or more Paying Agents (or,
if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as
provided in Section 4.04) an amount of money sufficient to redeem on the Redemption Date all the
New Notes (or portions thereof) so called for redemption (other than those theretofore surrendered
for conversion into Common Stock) at the appropriate Redemption Price; provided that if such
payment is made on the Redemption Date it must be received by the Trustee or Paying Agent, as the
case may be, by 11:00 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 Trustee or any 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 excluding, the Redemption Date.

     Notwithstanding the last sentence of Section 7.05, if any New Note called for redemption is
converted pursuant hereto prior to such Redemption Date, any money deposited with the Trustee or
any Paying Agent or so segregated and held in trust for the redemption of such New Note shall be
paid to the Company upon its written request, or, if then held by the Company, shall be discharged
from such trust. Whenever any New Notes are to be redeemed, the Company will give the Trustee
written notice in the form of an Officers’ Certificate not fewer than thirty (30) days (or such
shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date as to the
aggregate principal amount of New Notes to be redeemed.

     (d) If less than all of the outstanding New Notes are to be redeemed, the Trustee shall select
the New Notes or portions thereof of the Global Note or the New 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 New Note selected for partial
redemption is submitted for conversion in part after such selection, the portion of such New Note
submitted for conversion shall be deemed (so far as may be possible) to be from the portion
selected for redemption. The New Notes (or portions thereof) so selected shall be deemed duly
selected for redemption for all purposes hereof, notwithstanding that any such New Note is
submitted for conversion in part before the mailing of the Redemption Notice.

     Upon any redemption of less than all of the outstanding New Notes, the Company and the Trustee
may (but need not), solely for purposes of determining the pro rata allocation among such New Notes
as are unconverted and outstanding

25

 

at the time of redemption, treat as outstanding any New Notes
surrendered for conversion during the period of fifteen (15) days next preceding the mailing of a Redemption
Notice and may (but need not) treat as outstanding any New Note authenticated and delivered during
such period in exchange for the unconverted portion of any New Note converted in part during such
period.

     Section 3.03. Payment of New Notes Called for Redemption by the Company. If a Redemption
Notice has been given as provided in Section 3.02, the New Notes or portion of New Notes with
respect to which such notice has been given shall, unless converted 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 applicable Redemption Price, and on and after the Redemption Date (unless the
Company shall default in the payment of such New Notes at the Redemption Price) Interest on the New
Notes or portion of New Notes so called for redemption shall cease to accrue and, after the close
of business on the second Business Day immediately preceding the Redemption Date (unless the
Company shall default in the payment of such New Notes at the Redemption Price), such New Notes
shall cease to be convertible 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 New Notes except the right to receive the Redemption Price thereof. On
presentation and surrender of such New Notes at a place of payment in said Redemption Notice, the
said New Notes or the specified portions thereof shall be paid and redeemed by the Company at the
applicable Redemption Price; provided that if the applicable Redemption Date is 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 New Notes on the applicable Record Date instead of the
holders surrendering such New Notes for redemption on such date.

     Upon presentation of any New 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 New Notes, of authorized denominations, in principal amount equal to the
unredeemed portion of the New Notes so presented.

     Notwithstanding the foregoing, the Trustee shall not redeem any New Notes or mail any
Redemption Notice during the continuance of a default in payment of Interest on the New Notes. If
any New 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 New Note, if any, compounded semi-annually, and such New Note shall remain convertible into
Common Stock until the principal 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 New Notes.

26

 

     Section 3.04. Conversion Arrangement on Call for Redemption. In connection with any
redemption of New Notes, the Company may arrange for the purchase and conversion of any New Notes
called for
redemption by an agreement with one or more investment bankers or other purchasers to purchase
such New Notes by paying to the Trustee in trust for the Noteholders, on or prior to 11:00 a.m. New
York City time on the Redemption Date, an amount that, together with any amounts deposited with the
Trustee by the Company for the redemption of such New Notes, is not less than the Redemption Price
of such New Notes. Notwithstanding anything to the contrary contained in this Article 3, the
obligation of the Company to pay the Redemption Price of such New Notes shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, any New Notes not duly surrendered for conversion by the Noteholders
thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law,
acquired by such purchasers from such Noteholders and (notwithstanding anything to the contrary
contained in Article 14) surrendered by such purchasers for conversion, all as of immediately prior
to the close of business on the Business Day prior to the Redemption Date, subject to payment of
the above amount as aforesaid. The Trustee shall hold and pay to the Noteholders whose New Notes
are selected for redemption any such amount paid to it for purchase and conversion in the same
manner as it would moneys deposited with it by the Company for the redemption of New Notes.
Without the Trustee’s prior written consent, no arrangement between the Company and such purchasers
for the purchase and conversion of any New Notes shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and
the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability
or expense arising out of or in connection with any such arrangement for the purchase and
conversion of any New Notes between the Company and such purchasers, including the costs and
expenses incurred by the Trustee in the defense of any claim or liability arising out of or in
connection with the exercise or performance of any of its powers, duties, responsibilities or
obligations under this Indenture, except in the case of the Trustee’s negligence or willful
misconduct.

     Section 3.05. Repurchase of New Notes by the Company at Option of Noteholders upon a
Fundamental Change.

     (a) If a Fundamental Change shall occur at any time prior to Stated Maturity, each Noteholder
shall have the right, at such holder’s option, to require the Company to repurchase any or all of
such holder’s New 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 Company Notice,
which date shall be no more than thirty (30) Business Days after the date of the Fundamental Change
Company Notice (subject to extension to comply with applicable law) (the “Fundamental Change
Repurchase Date”). The Company

27

 

shall repurchase such New Notes at a price (the “Fundamental Change
Repurchase Price”) equal to 100% of the principal amount thereof plus any accrued and unpaid
Interest to but excluding the Fundamental Change Repurchase Date.

     (b) On or before the thirtieth (30th) 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 (5) 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 (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental
Change and of the repurchase right at the option of the Noteholders arising as a result thereof to
each Noteholder 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 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 Noteholder receives such notice. Each Fundamental Change Company
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, excluding accrued and unpaid Interest,

Interest that will be payable with respect to the New Notes on the Fundamental Change
Repurchase Date;

     (v) whether the Fundamental Change Repurchase Price will be paid in cash or shares of
Common Stock;

     (vi) if shares of Common Stock will be used to pay the Fundamental Change Repurchase
Price:

     (A) the method for valuing the shares of Common Stock to be delivered in
connection with the repurchase; and

28

 

     (B) that Noteholders will bear the market risk with respect to the value of
the shares of Common Stock to be delivered from the date the number of shares is
determined;

     (vii) the Fundamental Change Repurchase Date;

     (viii) the name and address of the Paying Agent and the Conversion Agent;

     (ix) that New Notes as to which a Fundamental Change Repurchase Notice has been given
by the holder may be converted only if the election has been withdrawn by the holder in
accordance with the terms of this Indenture; provided that the New Notes are otherwise
convertible in accordance with Section 14.01;

     (x) that the holder shall have the right to withdraw any New Notes surrendered prior
to the close of business on the Business Day immediately preceding the Fundamental Change
Repurchase Date (or any such later time as may be required by applicable law);

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

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

     (xiii) briefly, the conversion rights of the New Notes and whether, at the time of
such notice, the New Notes are eligible for conversion.

     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
New Notes pursuant to this Section 3.05.

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

     (i) delivery to the Trustee (or other Paying Agent appointed by the Company) by a
holder of a duly completed notice (a “Fundamental Change Repurchase Notice”) in the form
set forth on the reverse of the New Note at any time prior to the close of business on the
Business Day immediately preceding the Fundamental Change Repurchase Date (subject to
extension to comply with applicable law) stating:

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

29

 

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

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

     (ii) delivery or book-entry transfer of the New Notes to the Trustee (or other Paying
Agent appointed by the Company) simultaneously with or at any time after delivery of the
Fundamental Change Repurchase Notice (together with all necessary endorsements) at the
Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company) in
the City of Philadelphia, 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 3.05 only if the New
Notes so delivered or transferred to the Trustee (or other Paying Agent appointed by the
Company) shall conform in all respects to the description thereof in the related
Fundamental Change Repurchase Notice. All questions as to the validity, eligibility
(including time of receipt) and acceptance of any New Note for repurchase shall be
determined by the Company, whose determination shall be final and binding absent manifest
error.

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

     (d) The New Notes to be repurchased pursuant to this Section 3.05 shall be paid for in cash;
provided that upon the occurrence of a Fundamental Change that does not result in a Termination of
Trading, the New Notes to be repurchased may be paid for, at the election of the Company, in cash
or Common Stock, subject to the conditions set forth in clause (e) of this Section 3.05.

     (e) If the Company elects to pay the Fundamental Change Repurchase Price in Common Stock, the
number of shares of Common Stock to be paid will equal the quotient obtained by dividing (i) the
Fundamental Change Repurchase Price by (ii) 98% of the average Last Reported Sale Price of the
shares of Common Stock for the five consecutive Trading Day period immediately preceding the second
Business Day immediately preceding the Fundamental Change Repurchase Date, appropriately adjusted
to take into account the occurrence, during the period commencing on the first Trading Day during
the five Trading Day period and ending on the Fundamental Change Repurchase Date, of any event
described in Section 14.06, subject to the next succeeding paragraph. The Company shall designate,
in the Fundamental Change Company Notice

30

 

delivered pursuant to clause (b) of this Section 3.05,
whether it will repurchase the New Notes for cash or shares of Common Stock; provided that the
Company will pay cash in lieu of fractional shares of Common Stock. For purposes of determining
the existence of potential fractional interests, all New Notes subject to repurchase by the Company
held by a Noteholder shall be
considered together (no matter how many separate certificates are to be presented). The
Company may not change its election with respect to the consideration to be paid once the Company
has given its Fundamental Change Company Notice to holders except as set forth below in the event
of a failure to satisfy, prior to the close of business on the Business Day prior to the
Fundamental Change Repurchase Date, any condition to the payment of the Fundamental Change
Repurchase Price in shares of Common Stock.

     The Company shall, at least three Business Days prior to delivering the Fundamental Change
Company Notice, deliver an Officers’ Certificate to the Trustee specifying:

     (i) the manner of payment selected by the Company, and

     (ii) if the Company elects to pay the Fundamental Change Repurchase Price in shares
of Common Stock, that the conditions to such manner of payment set forth in this clause
(e) have been or will be complied with.

     The Company’s right to exercise its election to repurchase New Notes through the issuance of
shares of Common Stock shall be conditioned upon:

     (i) the Company’s giving a timely Fundamental Change Company Notice containing an
election to purchase all or a specified percentage of the New Notes with shares of Common
Stock as provided herein;

     (ii) the registration of such shares of Common Stock under the Securities Act and, if
required, the Exchange Act;

     (iii) the listing of such shares of Common Stock on a United States national
securities exchange or the quotation of such shares of Common Stock in an inter-dealer
quotation system of any registered United States national securities association, in each
case, if the Common Stock is then listed on a national securities exchange or quoted in an
inter-dealer quotation system;

     (iv) any necessary qualification or registration of such shares of Common Stock under
applicable state securities laws or the availability of an exemption from such
qualification and registration; and

31

 

     (v) the receipt by the Trustee of an (i) Officers’ Certificate stating that the terms
of the issuance of the shares of Common Stock are in conformity with this Indenture, (ii)
an Opinion of Counsel to the effect that the shares of Common Stock to be issued by the
Company in payment of the Fundamental Change Repurchase Price in respect of the New Notes
have been duly authorized and, when issued and delivered pursuant to the terms of
this Indenture in payment of the Fundamental Change Repurchase Price in respect of the New
Notes, will be validly issued, fully paid and non-assessable and (iii) an Officers’
Certificate, stating that the conditions to the issuance of the shares of Common Stock
have been satisfied.

     Such Officers’ Certificate shall also set forth the number of shares of Common Stock to be
issued for each $1,000 principal amount of New Notes and the Last Reported Sale Price of a share of
Common Stock on each Trading Day during the period commencing on the fifth Trading Day immediately
preceding but ending on the second Business Day prior to the applicable Fundamental Change
Repurchase Date. If the foregoing conditions are not satisfied prior to the close of business on
the Business Day immediately preceding the Fundamental Change Repurchase Date and the Company has
elected to repurchase the New Notes through the issuance of shares of Common Stock, the Company
shall pay the entire Fundamental Change Repurchase Price of the New Notes in cash.

     Promptly after determination of the actual number of shares of Common Stock to be issued upon
repurchase of New Notes, the Company shall be required to disseminate a press release through Dow
Jones & Company, Inc. or Bloomberg Business News containing this information or publish the
information on the Company’s web site or through such other public medium as the Company may use at
that time.

     All shares of Common Stock delivered upon repurchase of the New Notes shall be duly
authorized, validly issued, fully paid and non-assessable.

     If a holder of a repurchased New Note is paid in shares of Common Stock, the Company shall pay
any documentary, stamp or similar issue or transfer tax due on such issue of Common Stock.
However, the holder shall pay any such tax which is due because the holder requests the Common
Stock to be issued in a name other than the holder’s name. The Trustee (or other paying agent
appointed by the Company) may refuse to deliver the certificates representing the shares of Common
Stock being issued in a name other than the holder’s name until the Trustee (or other paying agent
appointed by the Company) receives a sum sufficient to pay any tax which will be due because the
shares of Common Stock are to be issued in a name other than the holder’s name. Nothing herein
shall preclude any income tax withholding required by law or regulations.

the Company to repurchase for cash all of such holder’s New Notes, or any portion of the principal
amount thereof that is an integral multiple of $1,000. The Company shall repurchase such New Notes
at a price (the “Company Repurchase Price”)
equal to 100% of the principal amount thereof plus any accrued and unpaid Interest to but
excluding the Company Repurchase Date.

     (a) On or before the twentieth (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 (5) 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

Note Register, and 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 Company Repurchase Price, excluding accrued and unpaid Interest, the
applicable Conversion Rate at the time of such notice (and any applicable adjustments to
the Conversion Rate) and, to the extent known at the time of such notice, the amount of
Interest that will be payable with respect to the New Notes on the Company Repurchase
Date;

     (ii) the Company Repurchase Date;

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

holder may be converted only if the election has been withdrawn by the holder in
accordance with the terms of this Indenture; provided that the New Notes are otherwise
convertible in accordance with Section 14.01;

33

 

     (vi) that the holder shall have the right to withdraw any New Notes surrendered prior
to the close of business on the Business Day immediately preceding the Company Repurchase
Date (or any such later time as may be required by applicable law);

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

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

     (ix) briefly, the conversion rights of the New Notes and whether, at the time of such
notice, the New Notes are eligible for conversion.

     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
New Notes pursuant to this Section 3.06.

     (b) New Notes shall be repurchased pursuant to this Section 3.06 at the option of the holder
upon:

     (i) delivery to the Trustee (or other Paying Agent appointed by the Company) by a
holder of a duly completed notice (a “Company Repurchase Election”) in the form set forth
on the reverse of the New Note at any time from the opening of business on the twentieth
(20th) Business Day preceding the Company Repurchase Date until the close of
business on the Business Day immediately preceding the Company Repurchase Date stating:

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

     (B) the portion of the principal amount of the New Notes that the holder
shall deliver to be repurchased, which portion must be $1,000 or an integral

Date pursuant to the terms and conditions specified in the New Notes and in the
Indenture; and

     (ii) delivery or book-entry transfer of the New Notes to the Trustee (or other Paying
Agent appointed by the Company) at any time after delivery of the Company Repurchase
Election (together with all necessary endorsements) at the Corporate Trust Office of the
Trustee (or other Paying Agent appointed by the Company) in the City of Philadelphia,

34

 

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 3.06 only if the New Notes so delivered or transferred to the Trustee (or
other Paying Agent appointed by the Company) 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 New Note for
repurchase shall be determined by the
Company, whose determination shall be final and binding absent manifest error.

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

     Section 3.07. [Reserved].

     Section 3.08. Conditions and Procedures for Repurchase at Option of Holders.

     (a) The Company shall repurchase from the holder thereof, pursuant to Section 3.05 or Section
3.06, a portion of a New 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 a New Note also
apply to the repurchase of any portion of such New Note. Upon presentation of any New 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 New Note or New
Notes, of any authorized denomination, in aggregate principal amount equal to the portion of the
New Notes presented not repurchased.

     (b) On or prior to a Repurchase Date, the Company will deposit with the Trustee or with one or
more Paying Agents (or, if the Company is acting as its own Paying Agent, set aside, segregate and
hold in trust as provided in Section 4.04) an amount of money or Common Stock, if permitted
hereunder, sufficient to repurchase on the Repurchase Date all the New Notes or portions thereof to
be repurchased on such date at the Repurchase Price; 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 11:00
a.m., New York City time, on such date.

     If the Trustee or other Paying Agent appointed by the Company, or the Company or an Affiliate
of the Company, if it or such Affiliate is acting as the Paying Agent, holds money or Common Stock,
if permitted hereunder, sufficient to pay the aggregate Repurchase Price of all the New Notes or
portions thereof that are to be repurchased on the Repurchase Date, then, on and after the Business
Day following such date (i) such New Notes will cease to be outstanding, (ii) Interest on such New
Notes will cease to accrue (whether or not book-entry

35

 

transfer of the New Notes has been made or
the New Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the
holders of such New Notes will terminate (other than the right to receive the Repurchase Price upon
transfer or delivery of the New Notes).

     (c) Upon receipt by the Trustee (or other Paying Agent appointed by the Company) of a
Repurchase Election, the holder of the New Note in respect of which such Repurchase Election was
given shall (unless such notice
is validly withdrawn) thereafter be entitled to receive solely the Repurchase Price with
respect to such New Note. Such Repurchase Price shall be paid to such holder, subject to receipt
of funds and/or New Notes by the Trustee (or other Paying Agent appointed by the Company), promptly
(but in no event more than five (5) Business Days) following the later of (x) the Repurchase Date
with respect to such New Note (provided the holder has satisfied the conditions in Section 3.05(c)
or Section 3.06(b), as applicable) and (y) the time of book-entry transfer or delivery of such New
Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the
manner required by Section 3.06(a) or Section 3.06(b), as applicable. New Notes in respect of
which a Repurchase Election has been given by the holder thereof may not be converted pursuant to
Article 14 hereof on or after the date of the delivery of such Repurchase Election unless such
notice has first been validly withdrawn.

     (d) Notwithstanding anything herein to the contrary, any holder delivering to the office of
the Trustee (or other Paying Agent appointed by the Company) a Repurchase Election shall have the
right to withdraw such election, in whole or in part, at any time prior to the close of business 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 Trustee (or other Paying Agent
appointed by the Company) specifying:

     (i) the principal amount of the New Note with respect to which such notice of
withdrawal is being submitted,

     (ii) the certificate number, if any, of the New Note in respect of which such notice
of withdrawal is being submitted, or the appropriate Depositary information if the New
Note in respect of which such notice of withdrawal is being submitted is represented by a
Global Note, and

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

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

36

 

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

     If a Repurchase Election is given and then withdrawn pursuant to this Section 3.08(d) the
Company shall have no obligation to purchase the New Notes listed in such Repurchase Election.

     (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 New 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 New Notes.

     (f) There shall be no repurchase of any New Notes pursuant to Section 3.05 or Section 3.06 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 New Notes). The Paying Agent will promptly return to the respective holders
thereof any New 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 New Notes) in
which case, upon such return, the Repurchase Election with respect thereto shall be deemed to have
been withdrawn.

     (g) The Trustee (or other Paying Agent appointed by the Company) shall return to the Company
any cash that remains unclaimed as provided in Section 12.03, 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 3.08(b) exceeds the aggregate
Repurchase Price of the New 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 Trustee shall return any such excess to the
Company together with interest, if any, thereon.

     (h) In the case of a reclassification, change, consolidation, merger, binding share exchange,
combination, sale or conveyance to which Section 14.08 applies, in which the Common Stock of the
Company 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 Company 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

37

 

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), then the Person formed by
such consolidation or resulting from such merger or which acquires such assets, as the case may be,
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) modifying the provisions of this Indenture
relating to the right of holders of the New Notes to
cause the Company to repurchase the New Notes following a Fundamental Change, including
without limitation 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
Company (in lieu of the Company).

ARTICLE 4

Particular Covenants of the Company and the Guarantor

     Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it

this Indenture may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency not designated or appointed by

or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office.

     The Company may also from time to time designate co-registrars and one or more offices or
agencies where the New Notes may be presented or surrendered for any or all such purposes and may
from 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.

38

 

     The Company hereby initially designates the Trustee as Paying Agent, Note Registrar,
Custodian, Bid Solicitation Agent and Conversion Agent, and each of the Corporate Trust Office and
the office of agency of the Trustee in the City of Philadelphia shall be considered as one such
office or agency of the Company for each of the aforesaid purposes.

     So long as the Trustee is the Note Registrar, the Trustee agrees to mail, or cause to be
mailed, the notices set forth in Section 7.10 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 New 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:

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

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

     (iii) 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 of or Interest on the New
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 or Interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of any failure to take such action;

39

 

provided that if such deposit is made on the due date, such deposit shall be received by the Paying
Agent by 11:00 a.m., New York City time, on such date.

     (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of
the principal of or Interest on the New Notes, set aside, segregate and hold in trust for the
benefit of the holders of the New Notes a sum sufficient to pay such principal 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 New Notes) to make any payment of the
principal of or Interest on the New 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 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 or any Paying Agent to the Trustee,
the Company 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
in trust as provided in this Section 4.04 is subject to Section 12.02 and Section 12.03.

     The Trustee shall not be responsible for the actions of any other Paying Agents (including the
Company if acting as its own 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. [Reserved]

     Section 4.07. Stay, Extension and Usury Laws. The Company and the Guarantor covenant (to the
extent that they may lawfully do so) that they shall not at any time insist upon, plead, or in any

Indenture and the Company and the Guarantor (to the extent they may lawfully do so) hereby
expressly waive all benefit or advantage of any such law, and covenant that they 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.

cause to be furnished to the Trustee, semiannually, not more than fifteen (15) days after each
January 1 and July 1 in each year beginning with July 1, 2007, and at such other times as the
Trustee may request in writing, within thirty (30) days after receipt by the Company of any such
request (or such lesser time as the Trustee may reasonably request in order to enable it to timely
provide any notice to be provided by it hereunder), a list in such form as the Trustee may
reasonably require of the names and addresses of the holders of New Notes as of a date not more
than fifteen (15) days (or such other date as the Trustee may reasonably request in order to so
provide any such notices) prior to the time such information is furnished, except that no such list
need be furnished by the Company to the Trustee so long as the Trustee is acting as the sole Note
Registrar.

     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 New Notes contained in the most recent
list furnished to it as provided in Section 5.01 or maintained by the Trustee in its capacity as
Note Registrar or co-registrar in respect of the New Notes, if so acting. The Trustee may destroy
any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished.

     (b) The rights of Noteholders to communicate with other holders of New Notes with respect to
their rights under this Indenture or under the New 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 New
Notes made pursuant to the Trust Indenture Act.

     Section 5.03. Reports by Trustee.

     (a) Within sixty (60) days after July 15 of each year commencing with the year 2007, the
Trustee shall transmit to holders of New Notes such reports dated as of September 15 of the year in
which such reports are made concerning the Trustee and its actions under this Indenture as may be
required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant
thereto. In the event that no events have occurred under the applicable sections of the Trust

42

 

Indenture Act, the Trustee shall be under no duty or obligation to provide such reports.

     (b) A copy of such report shall, at the time of such transmission to holders of New Notes, be
filed by the Trustee with each stock exchange and automated quotation system upon which the New
Notes are listed and with the Company. The Company will promptly notify the Trustee in writing

provided pursuant to such Act, whether or not the New Notes are governed by such Act; provided that
any such information, documents or reports required to be filed with the Commission pursuant to
Section 13 or 15(d) of the
Exchange Act shall be filed with the Trustee within fifteen (15) 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 Trustee’s receipt of such shall not
constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

ARTICLE 6

Remedies of the Trustee and Noteholders on an Event of Default

this Indenture (other than a
covenant or agreement a default in whose performance or whose breach is elsewhere in this
Section 6.01 specifically dealt with) continued for a period of sixty (60) days after the date on
which written notice of such failure, requiring the Company or the Guarantor to remedy the same,
shall have been given to the Company or the Guarantor by the Trustee, or to the Company or the
Guarantor and a Responsible Officer of the Trustee by the holders of at least twenty-five percent
(25%) in aggregate principal amount of the New Notes at the time outstanding determined in
accordance with Section 8.04; or

     (i) default with respect to the Company’s or any of its Significant Subsidiaries’ Indebtedness
having a principal amount then outstanding, individually or in the aggregate, of at least $25.0
million, whether such Indebtedness now exists or is hereafter incurred, which default or defaults:

     (i) shall have resulted in such Indebtedness becoming or being declared due and
payable prior to the date on which it would otherwise have become due and payable and such
acceleration shall not have been rescinded or annulled within 60 days after the date of
such acceleration; or

     (ii) shall constitute the failure to pay such Indebtedness at the final stated
maturity thereof (after expiration of any applicable grace period); or

     (j) rendering of any final judgment or judgments for the payment of money in excess of $25.0

44

 

any period of sixty (60) consecutive days
during which a stay of enforcement shall not be in effect; or

     (k) commencement by the Company of a voluntary case or other proceeding seeking liquidation,
reorganization or other relief with respect to the Company 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 or any substantial part of
the property of the Company, or consent by the Company 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 or general assignment by the Company for the benefit of creditors, or failure
of the Company generally to pay its debts as they become due; or

     (l) commencement of an involuntary case or other proceeding against the Company seeking
liquidation, reorganization or other relief with respect to the Company 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 or any
substantial part of the property of the Company and such involuntary case or other proceeding shall
remain undismissed and unstayed for a period of sixty(60) consecutive days;

     then, and in each and every such case (other than an Event of Default specified in Section
6.01(k) or 6.01(l), unless the principal of all of the New Notes shall have already become due and
payable, either the Trustee or the holders of not less than twenty-five percent (25%) in aggregate
principal amount of the New 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 of all the New Notes and any Interest accrued 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 New Notes contained to the contrary notwithstanding.
If an Event of Default specified in Section 6.01(k) or Section 6.01(l) occurs, the principal of all
the New Notes and any Interest accrued thereon shall be immediately and automatically due and
payable without necessity of further action. This provision, however, is subject to the conditions
that if, at any time after the principal of the New 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, the Company shall pay or shall deposit with the
Trustee a sum sufficient to pay all matured installments of Interest upon all New Notes and the
principal of any and all New Notes which shall have become due otherwise than by acceleration (with
interest on overdue installments of Interest (to the extent that payment of such interest is
enforceable under applicable law) and on such principal at the rate borne by the New Notes, to the
date of such payment or deposit) and amounts due to the Trustee pursuant to Section 7.06, and if
any and

45

 

all defaults under this Indenture, other than the nonpayment of principal of and accrued
Interest on New Notes which shall have become due by acceleration, shall have been cured or waived
pursuant to Section 6.07, then and in every such case the holders of a majority in aggregate
principal amount of the New 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; 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.

     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 New 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 New Notes, and the Trustee shall continue as though no such
proceeding had been taken.

     Section 6.02. Payments of New Notes on Default; Suit Therefor. The Company covenants that
(a) in case default shall be made in the payment of any installment of Interest upon any of the New
Notes as and when
the same shall become due and payable, and such default shall have continued for a period of
thirty (30) days, or (b) in case default shall be made in the payment of the principal of any of
the New Notes as and when the same shall have become due and payable, whether at maturity of the
New Notes or in connection with any redemption, repurchase, acceleration, declaration or otherwise,
then, upon demand of the Trustee, the Company, or the Guarantor, in accordance with Article 15,
will pay to the Trustee, for the benefit of the holders of the New Notes, the whole amount that
then shall have become due and payable on all such New Notes for principal or Interest, as the case
may be, with interest upon the overdue principal 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 New Notes, and, in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other amounts due the Trustee under Section 7.06. Until such demand
by the Trustee, the Company may pay the principal of and Interest on the New Notes to the
registered holders, whether or not the New 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

46

 

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 New Notes and collect in
the manner provided by law out of the property of the Company or any other obligor on the New 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 or any other obligor on the New 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 or such other obligor, the property of the Company, or such other obligor, or in the
case of any other judicial proceedings relative to the Company or such other obligor upon the New
Notes, or to the creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the New 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 principal and Interest owing and unpaid in respect of the New 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 New 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.
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 New Notes may be entitled
to receive in such proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

47

 

     All rights of action and of asserting claims under this Indenture, or under any of the New
Notes, may be enforced by the Trustee without the possession of any of the New 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 New 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 New Notes, and it shall not be necessary to make any holders of
the New 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 New 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 of the outstanding New Notes shall not have become due and be
unpaid, to the payment of Interest on the New 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) upon the overdue installments of Interest at the rate borne by the New Notes, such
payments to be made ratably to the Persons entitled thereto;

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

48

 

     FOURTH: To the payment of the remainder, if any, to the Company, the Guarantor, or any other
Person lawfully entitled thereto.

     Section 6.04. Proceedings by Noteholder. No holder of any New 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 such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless
also the holders of not less than twenty-five percent (25%) in aggregate principal amount of the
New 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 reasonable security or indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for sixty (60) 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 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 New Note with every other
taker and holder and the Trustee, that no one or more holders of New 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 Noteholders, 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 New
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 New Note, the
right of any holder of any New Note to receive payment of the principal of (including any
Redemption Price or Repurchase Price pursuant to Article 3) and accrued Interest on such New Note
on or after the respective due dates expressed in such New Note, or to institute suit for the
enforcement of any such payment on or after such respective dates against the Company or any
Guarantor, shall not be impaired or affected without the consent of such holder.

     Anything in this Indenture or the New Notes to the contrary notwithstanding, the holder of any
New Note, without the consent of either the Trustee or the holder of any other New 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 conversion as provided herein.

49

 

     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 New 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
New 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.
Upon provision of indemnity reasonably satisfactory to the Trustee, the holders of a majority in
aggregate principal amount of the New 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 and (c) the Trustee may decline to take any action that would
benefit some Noteholders to the detriment of other Noteholders. The holders of a majority in
aggregate principal amount of the New Notes at the time outstanding determined in accordance with
Section 8.04 may, on behalf of the holders of all of the New 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 of, the New Notes, (ii) a failure by the Company to convert any New Notes into Common
Stock or cash, (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 3.05
or Company Repurchase Price pursuant to Section 3.06 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 New Notes then outstanding or

50

 

affected thereby. Upon any such waiver, the Company, the Guarantor,
the Trustee and the holders of the New 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 New 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 (90) days after a
Responsible Officer of the Trustee has 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 of or Interest on any of the New 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 New 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 New 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 of or Interest on any New Note on or after the due date expressed in such New Note or to
any suit for the enforcement of the right to convert any New 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

     (e) if any party fails to deliver a notice relating to an event the fact of which, pursuant to

Trustee may conclusively rely on its failure to receive such notice as reason to act as if no
such event occurred.

     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

Company or the holders of at least 10% in aggregate principal amount of the New Notes and such

     (i) the Trustee may request that the Company or the Guarantor 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

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 reasonably
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 also covenants 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

55

 

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 Guarantor, any holder or any other Person) of liability in
connection with the exercise or performance of any of its powers or duties hereunder. The
obligations of the Company 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 New 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 New Notes. The
obligation of the Company under this Section 7.06 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(k) or Section 6.01(l) with respect to the
Company, the Guarantor or any Significant Subsidiary 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

56

 

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 New 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 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 sixty (60) days after the mailing of such notice of
resignation to the Noteholders, the resigning Trustee may, upon ten (10) Business Days’ notice to
the Company and the Noteholders, appoint a successor identified in such notice or may 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 New Note or New Notes for at
least six (6) 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 New Note or New
Notes for at least six (6) 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,

57

 

     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 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 New
Note or New Notes for at least six (6) 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 sixty (60) 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 New 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 (10) 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 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, to the Guarantor, 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 and the Guarantor 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,

58

 

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 New 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 of the Company) shall mail or cause to be
mailed notice of the succession of such trustee hereunder to the holders of New Notes at their
addresses as they shall appear on the Note Register. If the Company fails to mail such notice
within ten (10) 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 New 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 New Notes so
authenticated; and in case at that time any of the New Notes shall not have been authenticated, any
successor to the Trustee or any authenticating agent appointed by such successor trustee may
authenticate such New 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 New Notes or in this Indenture;
provided that the right to adopt the certificate of authentication of any predecessor Trustee or
authenticate New 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 New

59

 

Notes), the Trustee shall be subject
to the provisions of the Trust Indenture Act regarding the collection of the claims against the
Company or the Guarantor (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 New 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 New 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 New 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 (15) 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 Section 7.01,
Section 7.02 and Section 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 New Notes shall be proved by the registry of such New 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 Guarantor, the Trustee, any
Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name such
New Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner
of such New Note (whether or not such New 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 of and Interest on such New
Note, for conversion of such New Note and for all other purposes; and neither the Company, nor the
Guarantor,

60

 

nor the Trustee nor any Paying Agent nor any Conversion Agent nor 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 New Note.

     Section 8.04 . Company-owned New Notes Disregarded. In determining whether the holders of
the requisite aggregate principal amount of New Notes have concurred in any direction, consent,
waiver or other action under this Indenture, New Notes which are owned by the Company, the
Guarantor or any other obligor on the New Notes or any Affiliate of the Company, the Guarantor or
any other obligor on the New 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
New Notes which a Responsible Officer knows are so owned shall be so disregarded. New 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 New Notes and that the pledgee is not the Company, any other obligor on the New Notes
or any Affiliate of the Company, the Guarantor 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 or any
Guarantor shall furnish to the Trustee promptly an Officers’ Certificate listing and
identifying all New Notes, if any, known by the Company or any Guarantor, as the case may be, 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 New 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 New Notes specified in this
Indenture in connection with such action, any holder of a New Note which is shown by the evidence
to be included in the New 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 8.01, revoke such action so far as concerns such New Note. Except as aforesaid, any
such action taken by the holder of any New Note shall be conclusive and binding upon such holder
and upon all future holders and owners of such New Note and of any New Notes issued in exchange or
substitution therefor, irrespective of whether any notation in regard thereto is made upon such New
Note or any New Note issued in exchange or substitution therefor.

61

may, from time to time, and at any time enter into an indenture or indentures supplemental hereto
for one or more of the following purposes:

     (a) to make provision with respect to the conversion rights of the holders of New Notes
pursuant to the requirements of Section 14.08 or the repurchase obligations of the Company pursuant
to the requirements of Section 3.08(h).

64

 

     (b) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the New

     (c) to evidence the assumption by a successor Person of the obligations of the Company or the
Guarantor pursuant to Article 11;

     (d) to add to the Events of Default and covenants of the Company or the Guarantor such further
Events of Default and covenants for the benefit of the holders of New Notes, and to make the
occurrence, or the occurrence and continuance, of a default in any such additional covenants a
default or an Event of Default permitting the enforcement of all or any of the several remedies
provided in this Indenture as herein set forth or to surrender any power conferred upon the Company
or any Guarantor; provided that in respect of any such additional covenant such supplemental
indenture may provide for a particular period of grace after default (which period may be shorter
or longer than that allowed in the case of other defaults) or may provide for an immediate
enforcement upon such default or may limit the remedies available to the Trustee upon such default;

     (e) to establish the forms or terms of the New Notes;

     (f) to cure any ambiguity or correct any error in this Indenture;

     (g) to evidence the acceptance of appointment hereunder by a successor Trustee with respect to
the New Notes;

     (h) to modify, eliminate or add to the provisions of this Indenture to such extent as shall be
necessary to qualify or maintain the qualification of this Indenture under the Trust Indenture Act,
or under any similar federal statute hereafter enacted;

     (i) to increase the Conversion Rate;

     (j) to facilitate the discharge of the New Notes;

     (k) to facilitate the registration of the New Notes; or

     (l) to make other changes to the Indenture or forms or terms of the New Notes, provided no
such change individually or in the aggregate with all other such changes has or will have a
material adverse effect on the interests of the Noteholders.

     Upon the written request of the Company and the Guarantor accompanied by a copy of each Board
Resolution and Member Action authorizing the execution of any supplemental indenture, the Trustee
is hereby authorized to join with the Company and the Guarantor in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations that may

65

 

be
therein contained and to accept the conveyance, transfer and assignment of any property thereunder,
but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental
indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise.

     Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed
by the Company, the Guarantor, and the Trustee without the consent of the holders of any of the New
Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02.

     Section 10.02 . Supplemental Indenture with Consent of Noteholders. With the consent
(evidenced as provided in Article 8) of the holders of at least a majority in aggregate principal
amount of the New Notes at the time outstanding, the Company and the Guarantor, when authorized by
Board Resolution and Member Action, and the Trustee may, from time to time and at any time, enter
into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or any supplemental
indenture or of modifying in any manner the rights of the holders of the New Notes; provided that
no such supplemental indenture shall (A) extend the Stated Maturity of any New Note, or (B) reduce
the rate or extend the time for payment of Interest thereon, or (C) reduce the principal amount
thereof, or (D) reduce any amount payable on redemption or repurchase thereof, or (E) impair the
right of any Noteholder to institute suit for the payment thereof, or (F) make the principal
thereof or Interest thereon payable in any coin or currency other than that provided in the New
Notes, or (G) affect the obligation of the Company to redeem any New Note on a Redemption Date in a
manner adverse to the holders of New Notes, or (H) affect the obligation of the Company to
repurchase any New Note upon the happening of a Fundamental Change in a manner adverse to the
holders of New Notes, or (I) affect the obligation of the Company to repurchase any New Note on a
Company Repurchase Date in a manner adverse to the holders of New Notes, or (J) impair the right to
convert the
New Notes into Common Stock subject to the terms set forth herein,
including Section 14.08, or
(K) reduce the number of shares of Common Stock, the amount of cash or the amount of other property
receivable upon conversion, in each case, without the consent of the holder of each New Note so
affected, or (L) modify any of the provisions of this Section 10.02 or Section 6.07, except to
increase any such percentage or to provide that certain other provisions of this Indenture cannot
be modified or waived without the consent of the holder of each New Note so affected, or (M) reduce
the quorum or voting requirements set forth in Article 9 or (N) reduce the aforesaid percentage of
New Notes, the holders of which are required to consent to any such supplemental indenture, without
the consent of the holders of all New Notes then outstanding.

     Upon the written request of the Company and the, accompanied by a copy of each Board
Resolution and Member Action authorizing the execution of any

66

 

such supplemental indenture, and upon
the filing with the Trustee of evidence of the consent of Noteholders as aforesaid, the Trustee
shall join with the Company and the Guarantor in the execution of such supplemental indenture
unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under
this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

     It shall not be necessary for the consent of the Noteholders under this Section 10.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

     Section 10.03 . Effect of Supplemental Indenture. Any supplemental indenture executed
pursuant to the provisions of this Article 10 shall comply with the Trust Indenture Act, as then in
effect, provided that this Section 10.03 shall not require such supplemental 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 or the Indenture has been qualified under
the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to
such supplemental 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 or the Indenture has
been qualified under the Trust Indenture Act. Upon the execution of any supplemental indenture
pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitation of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Company, the Guarantor and the
holders of New Notes shall thereafter be determined, exercised and enforced hereunder, subject in
all respects to such modifications and amendments and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes.

     Section 10.04 . Notation on New Notes. New Notes authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this Article 10 may bear a
notation in form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company or the Trustee shall so determine, New Notes so modified as to conform,
in the opinion of the Trustee and the Board of Directors of the Company, to any modification of
this Indenture contained in any such supplemental indenture may, at the Company’s expense, be
prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly
appointed by the Trustee pursuant to Section 18.13) and delivered in exchange for the New Notes
then outstanding, upon surrender of such New Notes then outstanding.

67

 

     Section 10.05 . Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee.
Prior to entering into any supplemental indenture, the Trustee shall be provided with an Officers’
Certificate of the Company and an Opinion of Counsel as conclusive evidence that any supplemental
indenture executed pursuant hereto complies with the requirements of this Article 10 and is
otherwise authorized or permitted by this Indenture.

ARTICLE 11

Consolidation, Merger, Sale, Conveyance and Lease

     Section 11.01 . Company or Guarantor May Consolidate on Certain Terms. Subject to the
provisions of Section 11.02, the Company shall not consolidate with or merge with or into any other
Person or Persons (whether or not affiliated with the Company), nor shall the Company or any of its
successors be a party or parties to successive consolidations or mergers, nor shall the Company
sell, convey, transfer or lease the property and assets of the Company substantially as an
entirety, to any other Person (whether or not affiliated with the Company), unless: (i) the Company
is the surviving Person, or the resulting, surviving or transferee Person, if other than the
Company is a corporation organized and existing under the laws of the United States of America, any
state thereof or the District of Columbia; (ii) upon any such consolidation, merger, sale,
conveyance, transfer or lease, the due and punctual payment of the principal of and Interest on all
of the New Notes, according to their tenor and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed by the Company shall be
expressly assumed, by supplemental indenture satisfactory in form to the Trustee, executed and
delivered to the Trustee by the Person (if other than the Company) formed by such consolidation, or
into which the Company shall have been merged, or by the Person that shall have acquired or leased
such property, and such supplemental indenture shall provide for the applicable conversion rights
set forth in Section 14.08; and (iii) immediately after giving effect to the transaction described
above, no Event of Default, and no event which, after notice or passage of time or both, would
become an Event of Default, shall have happened and be continuing.

     Section 11.02 . Successor to Be Substituted. In case of any such consolidation, merger,
sale, conveyance, transfer or lease 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 of and Interest on all of the New Notes
and the due and punctual performance of all of the covenants and conditions of this Indenture to be
performed by the Company, such successor Person shall succeed to and be substituted for the
Company, with the same effect as if it had been named herein as the party of this first part. Such
successor Person thereupon may

68

 

cause to be signed, and may issue either in its own name, or in the
name of the Company, any or all of the New 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 New Notes that previously shall have been signed and delivered by
the officers of the Company to the Trustee for authentication, and any New Notes that such
successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose.
All the New Notes so issued shall in all respects have the same legal rank and benefit under this
Indenture as the New Notes theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such New 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”, 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 New Notes and from its obligations under this Indenture.

     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 New 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

Satisfaction and Discharge of Indenture

     Section 12.01 . Discharge of Indenture. When (a) the Company shall deliver to the Trustee
for cancellation all New Notes theretofore authenticated (other than any New Notes that have been
destroyed, lost or stolen and in lieu of or in substitution for which other New Notes shall have
been authenticated and
delivered) and not theretofore canceled, or (b) all the New Notes not theretofore canceled or
delivered to the Trustee for cancellation shall have become due and payable and the Company shall
deposit with the Trustee or with one or more Paying Agents (or, if the Company is acting as its own
Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04), in trust, funds
sufficient to pay all amounts due and owing on New Notes (other than any New Notes that shall have
been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other New
Notes shall have been authenticated and delivered) not

69

 

theretofore canceled or delivered to the
Trustee for cancellation, and if in either case the Company shall also pay or cause to be paid all
other sums payable hereunder by the Company (including Common Stock, as applicable), then this
Indenture shall cease to be of further effect (except as to (i) remaining rights of registration of
transfer, substitution and exchange and conversion of New Notes, (ii) rights hereunder of
Noteholders to receive payments of principal of and Interest on the New Notes and the other rights,
duties and obligations of Noteholders, as beneficiaries hereof with respect to the amounts, if any,
so deposited with the Trustee and (iii) the rights, obligations and immunities of the Trustee
hereunder, including those pursuant to Section 7.06), and the Trustee, on written demand of the
Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section
18.06 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 New 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 New 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 of or Interest on New
Notes and not applied but remaining unclaimed by the holders of New Notes for two years after the
date upon which the principal of or Interest on such New Notes, as the case may be, shall have
become due and payable, shall be repaid to the Company by the Trustee on demand and all liability
of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the New
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, Shareholders, Members, Officers and Directors

     Section 13.01 . Indenture, New Notes and Guarantee Solely Corporate or Limited Liability
Company Obligations, as the Case May Be. No recourse for the payment of the principal of or
Interest on any New Note, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any

70

 

obligation, covenant or agreement of the Company or the Guarantor in
this Indenture or in any supplemental indenture or in any New Note, or because of the creation of
any Indebtedness represented thereby, or for any of the obligations of the Guarantor under the
Guarantee, shall be had against any incorporator, shareholder, member, employee, agent, officer,
director or subsidiary, as such, past, present or future, of the Company, the Guarantor, or of any
successor corporation or limited liability company, either directly or through the Company, the
Guarantor or any successor corporation or limited liability company, 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, the issue
of the New Notes, and the issue of the Guarantee.

ARTICLE 14

Conversion of New Notes

     Section 14.01 . Right to Convert.

     (a) Subject to and upon compliance with the provisions of this Indenture including Section
14.03 hereof, prior to July 15, 2034, the holder of any New Note shall have the right, at such
holder’s option, to convert the principal amount of the New Note, or any portion of such principal
amount which is an integral multiple of $1,000 at the Conversion Rate in effect at such time, by
surrender of the New Note so to be converted 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. Settlement of conversions in cash or shares of Common Stock, or a combination thereof,
shall be made as set forth in Section 14.03 hereof. The New Notes shall be convertible only during
the following periods upon the occurrence of one of the following events:

     (i) during any calendar quarter commencing after the quarter ended March 31, 2007 and
before the Business Day immediately prior to the Stated Maturity (and only during such
calendar quarter) if the Last Reported Sale Price for the Common Stock for at least twenty
(20) Trading Days during the period of thirty (30) consecutive Trading Days ending on the
last Trading Day of the previous calendar quarter is greater than or equal to 120% of the
Conversion Price on such last Trading Day;

     (ii) in the event that the Company calls any or all of the New Notes for redemption,
at any time prior to the close of business on the second Business Day immediately
preceding the Redemption Date (unless the Company fails to pay the Redemption Price);
provided that only those

71

 

New Notes that are called for redemption may be converted
following such an event;

     (iii) during the five (5) consecutive Business Day period after any five (5)
consecutive Trading Day period in which the Trading Price per New Note, as determined
following a request by a holder in accordance with the procedures described below, for
each day of that period was less than 98% of the product of the Conversion Rate and the
Last Reported Sale Price of the Common Stock such day (the “98% Trading Exception”);
provided, however, that if on the date of any conversion pursuant to the 98% Trading
Exception that is on or after July 15, 2029, the Last Reported Sale Price of the Common
Stock on the Trading Day immediately prior to the Conversion Date is greater than 100% of
the Conversion Price, then Noteholders surrendering New Notes for conversion will receive,
in lieu of shares of Common Stock based on the Conversion Rate, shares of Common Stock
with a value equal to the principal amount of New Notes being converted (a “Principal
Value Conversion”). Shares of Common Stock delivered upon a Principal Value Conversion
will be valued at the greater of the effective Conversion Price as of the eighth day prior
to the Conversion Date and the Last Reported Sale Price as of the Conversion Date and will
be delivered no later than the third Business Day following the determination of the Last
Reported Sale Price; or

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

     In connection with any conversion pursuant to (iii), the Trustee shall have no obligation to
obtain the bids necessary for the Company to determine the Trading Price of the New Notes unless
the Company has requested it to do so, and the Company shall have no obligation to make such
request unless a holder provides the Company with reasonable evidence that the Trading Price per
New Note is less than 98% of the product of the Last Reported Sale Price of the Common Stock and
the Conversion Rate. At such time, the Company will instruct the Trustee to obtain the bids (in
the manner described in the definition of Trading Price) beginning on the next Trading Day and on
each successive Trading Day until the Trading Price per New Note is greater than or equal to 98% of
the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate.

     The Company or its designated agent shall determine on a daily basis during the time period
specified in Section 14.01(a)(i) and (iii) whether the New Notes shall be convertible as a result
of the occurrence of an event specified in clause (i) or (iii) above and, if the New Notes shall be
so convertible, the
Company shall promptly deliver to the Trustee (or other Conversion Agent appointed by the
Company) written notice thereof. Whenever the New Notes

72

 

shall become convertible pursuant to this
Section 14.01, the Company or, at the Company’s request, the Trustee in the name and at the expense
of the Company, shall notify the holders of the event triggering such convertibility in the manner
provided in Section 18.03, 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 Trustee shall be entitled at its sole discretion to consult with the Company and to
request the assistance of the Company in connection with the Trustee’s duties and obligations
pursuant to Section 14.01 hereof, and the Company agrees, if requested by the Trustee, to cooperate
with, and provide assistance to, the Trustee in carrying out its duties under this Section 14.01;
provided, however, that nothing herein shall be construed to relieve the Trustee of its duties
pursuant to Section 14.01 hereof.

     (b) In addition, if:

     (i) the Company distributes to all holders of Common Stock rights or warrants
entitling them to subscribe for or purchase (for a period expiring within 45 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 Company distributes to all holders of Common Stock assets, debt
securities or rights to purchase securities of the Company, which distribution has a per
share value as determined by the Board of Directors of the Company and set forth in a
Board Resolution exceeding 5% 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 New Notes may be surrendered for conversion at any time on and after the
date that the Company 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 the close of business on the Business Day immediately preceding, but not
including, the Ex-Dividend Date or the date the Company publicly announces that such
distribution will not take place; provided that no holder may exercise this right to
convert if the holder will otherwise participate in such distribution without conversion;

     (ii) the Company consolidates with or merges with or into another Person or is a
party to a binding share exchange, in each case pursuant to which the Common Stock is
converted into cash or property other than securities, then the New Notes may be
surrendered for conversion at any time from and after the date which is fifteen (15) days

73

 

prior to the anticipated effective date of the transaction until and including the
date which is fifteen (15) days after the actual effective date of the transaction. The
Board of Directors of the Company 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 (2) Business Days prior
to the 15th day prior to the anticipated effective date of the transaction. If New Notes
are not surrendered pursuant to this paragraph for conversion, at the effective time of
the transaction, the right to convert the New Notes into Common Stock will be changed into
a right to convert the New Notes into the kind and amount of, cash, securities or other
property that a Noteholder would have received if such holder had converted such holder’s
New Notes immediately prior to the applicable Record Date for such transaction.

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

     (d) Upon the occurrence of a Make-Whole Fundamental Change as defined in Section 14.07, and
notwithstanding whether any other condition to Holders’ conversion rights is also satisfied at such
time, the New Notes may be surrendered for conversion at any time from and after the Effective Date
(as defined in Section 14.07) of such Make-Whole Fundamental Change until and including the date
thirty (30) calendar days after such Effective Date, or, if such Make-Whole Fundamental Change also
constitutes a Fundamental Change, Holders shall have the right to cause the Company to repurchase
the New Notes pursuant to Section 3.05, until the related Fundamental Change Repurchase Date. The
Board of Directors of the Company 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 ten (10) calendar days prior to the anticipated
effective date of the Make-Whole Fundamental Change.

     Section 14.02 . Exercise of Conversion Privilege; No Adjustment for Interest or Dividends.
In order to exercise the conversion privilege with respect to any New 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 New Note with the original or facsimile
of the form entitled “Form of Notice of Conversion” on the reverse thereof, duly completed and
manually signed, together with the appropriate endorsements and transfer documents, and accompanied
by the funds, if any, required by this Section 14.02. Such notice (a “Notice of Conversion”) 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 conversion, if any, shall be issued, and
shall be accompanied by transfer or similar taxes, if required
pursuant to Section 14.09.

     In order to exercise the conversion privilege with respect to any interest in a Global Note,
the beneficial holder must complete, or cause to be completed, the appropriate instruction form for
conversion pursuant to the Depositary’s book-entry conversion 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 Conversion

74

 

Agent, and pay the
funds, if any, required by this Section 14.02 and any transfer taxes if required pursuant to
Section 14.09.

     As promptly as practicable after satisfaction of the requirements for conversion set forth
above, but no later than the fifth Business Day following receipt by the Company of a Notice of
Conversion, subject to Section 14.03 and subject also to compliance with any restrictions on
transfer if shares issuable on conversion are to be issued in a name other than that of the
Noteholder (as if such transfer were a transfer of the New Note or New Notes (or portion thereof)
so converted), the Company shall issue and shall deliver, or cause the Conversion Agent to deliver,
to such Noteholder at the office or agency maintained by the Company for such purpose pursuant to
Section 4.02, a certificate or certificates for the number of full shares of Common Stock issuable
upon the conversion of such New Note or portion thereof, if any, as determined by the Company in
accordance with the provisions of this Article 14 and a check or cash in respect of any cash
amounts due upon conversion, calculated by the Company as provided in Section 14.03. In case any
New Note of a denomination greater than $1,000 shall be surrendered for partial conversion, and
subject to Section 2.03, the Company shall execute and the Trustee shall authenticate and deliver
to the holder of the New Note so surrendered, without charge to him, a New Note or New Notes in
authorized denominations in an aggregate principal amount equal to the unconverted portion of the
surrendered New Note.

     Each conversion shall be deemed to have been effected as to any such New 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 New Note (or portion thereof) (such date, the “Conversion Date”), and the
Person in whose name any certificate or certificates for shares of Common Stock, if any, shall be
issuable upon such conversion shall be deemed to have become immediately prior to the close of
business on said date the holder of record of the shares represented thereby.

     Any New Note or portion thereof surrendered for conversion during the period from the close of
business on any Regular Record Date to the opening of business on the immediately following
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 converted; 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
prior to the next Interest Payment Date, (2) if the Company has specified a Repurchase Date
following a Fundamental Change that is after a Regular Record Date and on or prior to the next
Interest Payment Date or (3) to the extent of any overdue Interest, if any overdue Interest exists
at the time of conversion with respect to such New Note. Except as provided above in this Section
14.02, no payment or other adjustment

75

 

shall be made for Interest accrued on any New Note converted
or for dividends on any shares issued upon the conversion of such New Note as provided in this
Article 14.

     Upon the conversion of an interest in a Global Note, the Trustee (or other Conversion Agent
appointed by the Company), or the Custodian at the direction of the Trustee (or other Conversion
Agent appointed by the Company), 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
conversions of New Notes effected through any Conversion Agent other than the Trustee.

     Upon the conversion of a New Note, that portion of the accrued but unpaid Interest with
respect to the converted New 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 the Common
Stock (together with the cash payment, if any in lieu of fractional shares) in exchange for the New
Note being converted pursuant to the provisions hereof; and the cash or fair market value of such
shares of Common Stock (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 converted New Note and the accrued but
unpaid Interest to, but not including the Conversion Date, and the balance, if any, of such fair
market value of such cash or Common Stock (and any such cash payment) shall be treated as issued in
exchange for and in satisfaction of the right to convert the New Note being converted pursuant to
the provisions hereof.

     Section 14.03 . Payment and Delivery Due upon Conversion; Payment of Cash in Lieu of Common
Stock.

     (a) As set forth in this Section 14.03, the Company shall settle its obligation (the
“Conversion Obligation”) in respect of any conversion of New Notes, subject to the notice
requirements set forth in clause (b) below, (i) entirely in shares of Common Stock pursuant to
clause (c) below (plus cash in lieu of fractional shares), (ii) entirely in cash pursuant to clause
(d) below or (iii) in a combination of cash and shares of Common Stock, if any, pursuant to clause
(e) below upon the Company’s irrevocable election to do so. Settlement in cash or in shares of
Common Stock, as applicable, will occur on the third Business Day following the final day of the
Observation Period, unless settlement in Common Stock (plus cash in lieu of fractional shares)
pursuant to clause (c) below shall apply, in which case settlement will occur on the third Business
Day following the final day of the Cash Settlement Notice Period (for conversions prior to a
Redemption Notice) or on the third Business Day following the Conversion Date (for conversions
after a Redemption Notice).

76

 

     (b) Unless the Company elects to satisfy the Conversion Obligation for any New Note tendered
for conversion in cash (including, following its irrevocable election as described below in Section
14.03(e), the portion of the Daily Conversion Value in excess of $62.50) pursuant to this clause
(b), settlement of the Conversion Obligation shall occur in Common Stock pursuant to
clause (c) below (or, following its irrevocable election as described below in Section
14.03(e), cash and shares of Common Stock).

     (i) If the Company elects to satisfy such Conversion Obligation in cash (including,
following its irrevocable election described in Section 14.03(e) below, the portion of the
Daily Conversion Value in excess of $62.50) it shall notify each Noteholder tendering such
New Notes through the Trustee of such election at any time on or before the related Cash
Settlement Notice Period. If the Company timely makes such election, each such tendering
Noteholder may retract the Notice of Conversion at any time during the Conversion
Retraction Period. For the avoidance of doubt, no such retraction can be made (and a
Notice of Conversion shall be irrevocable) if the Company does not elect to deliver cash
in lieu of shares of Common Stock (other than cash in lieu of fractional shares).

     (ii) Notwithstanding clause (i) above, if the Company elects to redeem the New Notes,
it shall not send individual notices of its election to satisfy its Conversion Obligation
in cash as set forth above. Instead, the Company shall specify in its Redemption Notice,
whether it elects to satisfy its Conversion Obligation entirely in cash or in shares of
Common Stock or, if the Company has made the irrevocable election described below in
Section 14.03(e) below, whether it shall satisfy the portion of the Daily Conversion Value
in excess of $62.50 in cash or in shares of Common Stock. The elections so specified in
the Redemption Notice shall apply to all conversions following the date of such Redemption
Notice. On and after the date of its Redemption Notice and its specification of mode of
settlement, conversions will not be retractable and any Notice of Conversion shall be
irrevocable.

     (c) Unless the Company has elected, pursuant to clause (b) above, to settle its Conversion
Obligation in cash, or the Company has made the irrevocable election described in Section 14.03(e)
below, the Company shall deliver, for each $1,000 principal amount of New Notes, a number of shares
of Common Stock equal to the Conversion Rate (plus cash in lieu of any fractional shares) in the
manner set forth this Article 14.

     (d) If the Company elects to satisfy its Conversion Obligation entirely in cash pursuant to
clause (b) above, it shall pay, for each $1,000 principal amount of New Notes, an amount in cash
equal to the product of (x) the

77

 

arithmetic average of the Daily VWAP for each Trading Day of the
related Observation Period and (y) the applicable Conversion Rate.

     (e) At any time prior to the Stated Maturity, the Company may irrevocably elect, in its sole
discretion without the consent of the Noteholders, by notice to the Trustee and to the Noteholders
to satisfy in cash up to 100% of the principal amount of the New Notes converted after the date of
such election and,
to the extent the Daily Settlement Amounts exceed $62.50 as described below, cash or shares of
the Common Stock at its election. If the Company makes such an election, upon any conversion it
shall deliver, in respect of each $1,000 principal amount of New Notes converted, an amount (the
“Settlement Amount”) of cash and shares of Common Stock, if any, equal to the aggregate amount of
cash and shares of Common Stock for the Daily Settlement Amounts for each of the 16 Trading Days of
the related Observation Period.

     Section 14.04 . Fractional Shares. No fractional shares of Common Stock or scrip
certificates representing fractional shares shall be issued upon conversion of New Notes. If more
than one New Note shall be surrendered for conversion at one time by the same holder, the number of
full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the New Notes (or specified portions thereof to the extent permitted hereby) so
surrendered. If any fractional share of stock would be issuable upon the conversion of any New
Note or New Notes, the Company shall make an adjustment and payment therefor in cash to the
Noteholders at the Last Reported Sale Price on the last Trading Day immediately preceding the day
on which the New Notes (or specified portions thereof) are deemed to have been converted.

     Section 14.05 . Conversion Rate. Each $1,000 principal amount of the New Notes shall be
convertible into the number of shares of Common Stock specified in the form of New Note (herein
called the “Conversion Rate”) attached as Exhibit A hereto (initially 37.9561 shares), subject to
adjustment as provided in this Article 14.

     Section 14.06 . Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company as follows:

     (a) If the Company 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 Conversion Rate will be
adjusted based on the following formula:

	 	 	 	 	 
	CR’=CR0

	 	x
	 	     OS’
	 

	 	 	 	 
	 

	 	 	 	     OS0

     where,

78

 

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such event
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion 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 the opening of business on the
Business Day following the date fixed for such determination. The Company will not pay any
dividend or make any distribution on shares of Common Stock held in treasury by the Company. If
any dividend or distribution of the type described in this Section 14.06(a) is declared but not so
paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be
in effect if such dividend or distribution had not been declared.

     (b) If the Company issues to all or substantially all holders of its Common Stock any rights
or warrants entitling them for a period of not more than 45 days to subscribe for or purchase
shares of Common Stock, or securities convertible into shares of Common Stock, at a price per share
or a conversion price per share less than the Last Reported Sale Price of shares of Common Stock on
the Business Day immediately preceding the time of announcement of such issuance, the Conversion
Rate will be adjusted based on the following formula (provided that the Conversion Rate will be
readjusted to the extent that such rights or warrants are not exercised prior to their expiration):

	 	 	 	 	 
	CR’=CR0

	 	x
	 	     OS0 + X
	 

	 	 	 	 
	 

	 	 	 	     OS0 + Y

     where,

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such event
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion 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

79

 

	 	 	 	 	 
	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 for the ten consecutive Trading Days prior to the Business Day
immediately preceding the Ex-Dividend Date with respect to the issuance of such
rights.

     Such adjustment shall be successively made whenever any such rights or warrants are issued and
shall become effective immediately after the opening of business on the Business Day following the
date fixed for such determination.
The Company shall not issue any such rights, options or warrants in respect of shares of
Common Stock held in treasury by the Company. To the extent that shares of Common Stock are not
delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted
to the Conversion 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 Conversion Rate shall
again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the
determination of shareholders 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 the Last Reported Sale Price of shares of Common Stock on the
Business Day immediately preceding the time of announcement of such issuance, and in determining
the aggregate offering price of such shares of Common Stock, there shall be taken into account any
consideration received by the Company 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 Board of Directors of the Company.

     (c) If the Company distributes shares of its Capital Stock, evidences of its Indebtedness or
other assets or property of the Company to all or substantially all holders of the Common Stock,
excluding:

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

     (ii) dividends or distributions paid exclusively in cash referred to in clause (d)
below;

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

	 	 	 	 	 
	CR’=CR0

	 	x
	 	     SP0
	 

	 	 	 	 
	 

	 	 	 	     SP0 - FMV

80

 

     where,

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to such distribution
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after such distribution
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale Prices of the Common Stock for the
ten days prior to the Business Day
immediately preceding the Ex-Dividend Date with respect to such
distribution
	 
	 	 	 	 
	FMV

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

     Such adjustment shall become effective immediately prior to the opening of business on the
Business Day following the date fixed for the determination of shareholders entitled to receive
such distribution.

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

	 	 	 	 	 
	CR’=CR0

	 	x
	 	     SP0
	 

	 	 	 	 
	 

	 	 	 	     SP0 - C

     where,

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior to the Record Date for
such distribution
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after the Record Date for such

distribution
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale Prices of our Common Stock for the
ten consecutive Trading Days prior to the Business Day immediately preceding the
Ex-Dividend Date with respect to such distribution
	 
	 	 	 	 
	C

	 	=
	 	the amount in cash per share the Company distributes to holders of Common
Stock.

81

 

     Such adjustment shall become effective immediately prior to the opening of business on the
Business Day following the date fixed for the determination of shareholders entitled to receive
such distribution.

     (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for the Common Stock, to the extent that the cash and value of any other
consideration included in the payment per share of Common Stock 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 (the
“Expiration Time”), the Conversion Rate will be increased based on the following formula:

	 	 	 	 	 
	CR’=CR0

	 	x
	 	      AC + (SP’ x OS’)
	 

	 	 	 	 
	 

	 	 	 	      OS0 - SP’

     where,

	 	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect on
the date such tender or exchange offer expires
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion 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 Board of Directors of the Company) 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 for the ten
consecutive Trading Days commencing on the Trading Day next succeeding the date such
tender or exchange offer expires.

     If the Company is obligated to purchase shares pursuant to any such tender or exchange offer,
but the Company is permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the

82

 

Conversion Rate shall again be adjusted to be the Conversion 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
Conversion Rate, no adjustment to the Conversion Rate will be made.

     Except as stated herein, the Company will not adjust the Conversion Rate for the issuance of
shares of Common Stock or any securities convertible into or exchangeable for shares of Common
Stock or the right to purchase shares of Common Stock or such convertible or exchangeable
securities.

     (f) [Reserved]

     (g) Notwithstanding the foregoing provisions of this Section 14.06, no adjustment shall be
made thereunder, nor shall an adjustment be made to the ability of a holder of a New Note to
convert, for any distribution described therein if the holder will otherwise participate in the
distribution without conversion of such holder’s New Notes.

     (h) The Company may (but is not required to) make such increases in the Conversion Rate, in
addition to those required by clauses (a) through (e) of this Section 14.06 as the Board of
Directors of the Company 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
Conversion Rate by any amount for any period of at least twenty (20) days if the Board of Directors
of the Company shall have made a determination that such increase would be in the best interests of
the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased
pursuant to the preceding sentence, the Company shall mail to holders of record of the New Notes a
notice of the increase at least fifteen (15) days prior to the date the increased Conversion Rate
takes effect, and such notice shall state the increased Conversion Rate and the period during which
it will be in effect.

     (i) No adjustment to the Conversion Rate need be made:

     (i) upon the issuance of any shares of Common Stock pursuant to any present or future
plan providing for the reinvestment of dividends or interest payable on securities of the
Company and the investment of additional optional amounts in shares of Common Stock under
any plan;

83

 

     (ii) upon the issuance of any shares of Common Stock or options or rights to purchase
those shares pursuant to any present or future employee, director or consultant benefit
plan or program of or assumed by the Company or any of its Subsidiaries;

     (iii) upon the issuance of any shares of Common Stock pursuant to any option,
warrant, right, or exercisable, exchangeable or convertible security not described in
subclause (ii) above and outstanding as of the date the New Notes were first issued;

     (iv) if the Noteholders may participate in the transaction that would otherwise give
rise to an adjustment pursuant to this Section 14.06;

     (v) for a change in the par value of the Common Stock; or

     (vi) for accrued and unpaid Interest.

     (j) No adjustment to the Conversion Rate shall be required pursuant to this Section 14.06
until the earlier of (1) such time as the Company shall have mailed or caused to be mailed a
Redemption Notice to be made pursuant to Section 3.02, or (2) such adjustment would require an
increase or decrease of at least 1.0% in the Conversion Rate; provided, however, that any
adjustments which by reason of this clause (j) of Section 14.06 are not required to be made, shall
be carried forward and taken into account in any subsequent adjustment.

     (k) 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.

     (l) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate
setting forth the Conversion 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 Conversion Rate and may assume that the last Conversion 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 Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to the holder of each New Note at his last address appearing on
the Note Register provided for in Section 2.05, within twenty (20) days after execution of such
Officers’ Certificate. Failure to deliver such notice shall not affect the legality or validity of
any such adjustment.

84

 

     (m) In any case in which this Section 14.06 provides that an adjustment shall become effective
immediately after (i) a Record Date for an event, (ii) the date fixed for the determination of
shareholders entitled to receive a dividend or distribution pursuant to Section 14.06(a), (c), or
(d), (iii) a date fixed for the determination of shareholders entitled to receive rights or
warrants pursuant to Section 14.06(b), or (iv) the Expiration Time for any tender or exchange offer
pursuant to Section 14.06(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 New Note converted after such Determination Date and before the occurrence of such
Adjustment Event, the additional shares of Common Stock or other securities issuable upon such
conversion by reason of the adjustment required by such Adjustment Event over and above the Common
Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such
holder any amount in cash in lieu of any fractional shares of Common Stock pursuant to Section
14.04. For purposes of this (m), 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.

     (n) For purposes of this Section 14.06, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractional shares of Common Stock. The
Company will not pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

     (o) If, in connection with any adjustment to the Conversion Rate as set forth in this Section
14.06 a Noteholder shall be deemed for U.S. federal tax purposes to have received a distribution,
the Company may set off any withholding tax it is required to collect with
respect to any such deemed distribution against cash payments of interest in accordance with the
provisions of Article 2 hereof or from cash and shares of Common Stock, if any, otherwise
deliverable to a Noteholder upon a conversion of New Notes in

85

 

accordance with the provisions of
Section 14.03 hereof or a redemption or repurchase of a New Note in accordance with the provisions
of Article 3 hereof.

     Section 14.07.
Adjustment Upon Certain Fundamental Changes.

     (a) If the Effective Date (as defined below), of a transaction or event described in clause
(b) of the definition of Fundamental Change (without giving effect to subsection (i) of that
definition) occurs on or prior to July 15, 2011 (such transaction or event, a “Make-Whole
Fundamental Change”), and a Holder elects to convert its New Notes at any time during the time
period for conversion set forth in Section 14.01(d) (notwithstanding whether any other condition to
Holders’ conversion rights is also satisfied at such time), then the Conversion Rate for such New
Notes shall be increased by an additional number of shares of Common Stock (the “Additional
Shares”) as described below.

     (b) The number of Additional Shares shall be determined by reference to the table attached as
Schedule A to this Indenture, based on the actual effective date of such Make-Whole Fundamental
Change (the “Effective Date”) and the Stock Price; provided that if the Stock Price is between two
Stock Price amounts set forth in such table or the Effective Date is between two Effective Dates in
the table, the number of Additional Shares shall 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; provided further that if the Stock Price
exceeds $65.00 per share (subject to adjustment as set forth in clause (c) below) or less than
$21.37 per share (subject to adjustment as set forth in clause (c) below), then no Additional
Shares will be added to the Conversion Rate.

     (c) The Stock Prices set forth in the first column of the table in Schedule A hereto shall be
adjusted as of any date on which the Conversion Rate of the New Notes is adjusted pursuant to
Section 14.06. 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 Conversion Rate immediately prior to such adjustment and the denominator of which is the
Conversion Rate as so adjusted. The number of Additional Shares to be added to the Conversion Rate
will be adjusted in the same manner as the Conversion Rate as set
forth in Section 14.06.

     Section 14.08. Effect of Reclassification, Consolidation, Merger or Sale. If any of the
following events occur, namely (i) any reclassification or change of the outstanding shares of
Common Stock (other than a subdivision or combination to which Section 14.06(a) applies), (ii) any
consolidation, merger, binding share exchange or combination of the Company 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 or conveyance of
all or substantially all of the properties and assets of the Company to any other Person, in each
case 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 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 New Note shall be convertible into the kind and
amount of cash, securities or other property receivable 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 conversion of such New 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 14.08 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 adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article 14.

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

86

 

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

     If
this Section 14.08 applies to any event or occurrence, Section 14.06 shall not apply.

     Section 14.09 . Taxes on Shares Issued. The issuance of stock certificates on conversions of
New Notes shall be made without charge to the converting 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 New Note converted, 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 14.10 . Reservation of Shares, Shares to Be Fully Paid; Compliance with Governmental
Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out
of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock
to provide for the conversion of the New Notes from time to time as such New Notes are presented
for conversion.

     Before taking any action which would cause an adjustment increasing the Conversion Rate to an
amount that would cause the Conversion Price to be reduced below the then par value, if any, of the
shares of Common Stock issuable upon conversion of the New Notes, the Company 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 Conversion Rate.

     The Company covenants that all shares of Common Stock which may be issued upon conversion of
New Notes will upon issue be fully paid and non-assessable by the Company and free from all taxes,
liens and charges with respect to the issue thereof.

     The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of New Notes hereunder require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly and lawfully issued upon
conversion, the Company 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.

87

 

     The Company further covenants that, if at any time the Common Stock shall be listed on the New
York Stock Exchange, National Association of Securities Dealers Automated Quotation System or any
other national securities exchange or automated quotation system, the Company 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 conversion of the New Notes.

     Section 14.11 . Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to the Company or any Noteholders to determine
the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion
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 Conversion 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 conversion of any
New Note; and the Trustee and any other Conversion Agent make no representations with respect
thereto. Neither the Trustee nor any Conversion 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 New Note for the purpose of conversion 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
Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 14.08 relating either to the kind or amount of shares of
stock or securities or property (including cash) receivable by Noteholders upon the conversion of
their New Notes after any event referred to in such Section 14.08 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 14.12 . Notice to Holders Prior to Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 14.06; or

88

 

     (b) the Company 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 Company (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 Company is a party and for which approval of any shareholders of the Company 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 Company;

     the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at
his address appearing on the Note Register provided for in Section 2.05, as promptly as possible
but in any event at least ten (10) 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 14.13 . Shareholders. If the Company adopts or subsequently amends a shareholder
rights plan and if the rights provided for in such plan have separated from the shares of Common
Stock in accordance with the provisions of the applicable shareholder rights agreement so that the
holders of the New Notes would not be entitled to receive any rights in respect of Common Stock
issuable upon conversion of the New Notes, the conversion rate will be adjusted as if the Company
distributed to all holders of Common Stock shares of the Company’s Capital Stock, evidences of
Indebtedness or assets (including securities but excluding rights or warrants to purchase Common
Stock issued to all holders of Common Stock, Common Stock issued as a dividend or distribution on
Common Stock and cash distributions), subject to readjustment upon the subsequent expiration,
termination or redemption of the rights. In lieu of any such adjustment, the Company may amend any
such future shareholder rights agreement to provide that upon conversion of the New Notes the
holders will receive, in addition to the

89

 

Common Stock issuable upon such conversion, the rights
which would have attached to such Common Stock if the rights had not become separated from the
Common Stock under such applicable shareholder rights agreement.

ARTICLE 15

Guarantee

     Section 15.01 . Guarantee. Except as otherwise provided herein, the Guarantor hereby fully
and unconditionally guarantees to each holder of a New Note authenticated and delivered by the
Trustee, and to the Trustee on behalf of such Noteholder, the due and punctual payment of the
principal of and Interest on such New Note and all other obligations of the Company under this
Indenture when and as the same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, upon a Repurchase Date or otherwise, in accordance with the
terms of such New Note and of this Indenture (collectively, the “Indenture Obligations”). The
Guarantor hereby fully and unconditionally also guarantees to the Trustee the due and punctual
payment of all obligations of the Company to the Trustee under this Indenture. In case of the
failure of the Company punctually to make any such payment, the Guarantor hereby agrees to cause
such payment to be made punctually when and as the same shall become due and payable, whether at
the Stated Maturity, by acceleration, call for redemption, upon a Repurchase Date or otherwise, and
as if such payment were made by the Company.

     The Guarantor agrees that its obligations hereunder shall be absolute and unconditional,
irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such New
Note or this Indenture, the absence of any action to enforce the same or any release, amendment,
waiver or indulgence granted to the Company or the Guarantor or any consent to depart from any
requirement of any other guarantee of all or any of the New Notes or any other circumstances which
might otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor. The Guarantor hereby waives to the fullest extent permitted by law the benefits of
diligence, presentment, demand for payment, any requirement that the Trustee or any of the
Noteholders protect, secure, perfect or insure any security interest in or other lien on any
property subject thereto or exhaust any right or take any action against the Company or any other
Person or any collateral, filing of claims with a court in the event of insolvency or bankruptcy of
the Company, any right to require a proceeding first against the Company, protest or notice with
respect to such New Note or the Indebtedness evidenced thereby and all demands whatsoever, and
covenants that the Guarantee will not be discharged in respect of such New Note except by complete
performance of the payment obligations contained in such New Note and in the Guarantee. The
Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default,
the

90

 

Trustee or any of the Noteholders are prevented by applicable law from exercising their
respective rights to accelerate the maturity of the New Notes, to collect Interest on the New
Notes, or to enforce or exercise any other right or remedy with respect to the New Notes, the
Guarantor agrees to the fullest extent permitted by law to pay to the Trustee for the account of
the Noteholders, upon demand therefor, the amount that would otherwise have been due and payable
had such rights and remedies been permitted to be exercised by the Trustee or any of the
Noteholders.

     The Guarantor shall be subrogated to all rights of the holders of the New Notes upon which its
Guarantee is endorsed against the Company in respect of any amounts paid by the Guarantor on
account of such New Note pursuant to the provisions of its Guarantee or this Indenture; provided,
however, that the Guarantor shall not be entitled to enforce or to receive any payment arising out
of, or based upon, such right of subrogation until the principal of and Interest, if any, on all
New Notes issued hereunder shall have been paid in full.

     The Guarantee shall remain in full force and effect and continue to be effective should any
petition be filed by or against the Company for liquidation or reorganization, should the Company
become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee
be appointed for all or any part of the Company’s assets, and shall, to the fullest extent
permitted by law, continue to be effective or be reinstated, as the case may be, if at any time
payment and performance of the New Notes is, pursuant to applicable law, rescinded or reduced in
amount, or must otherwise be restored or returned by any Noteholder, whether as a “voidable
preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not
been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or
returned, the New Notes shall, to the fullest extent permitted by law, be reinstated and deemed
reduced only by such amount paid and not so rescinded, reduced, restored or returned.

     Any term or provision of any Guarantee to the contrary notwithstanding, the aggregate amount
of the obligations guaranteed hereunder shall be reduced to the extent necessary to prevent such
Guarantee from violating or becoming
voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

     Section 15.02 . Execution and Delivery of Guarantee. The Guarantee to be endorsed on the New
Notes shall include the terms and shall be substantially in the form of the Guarantee set forth in
Exhibit A. The Guarantor hereby agrees to execute its Guarantee, in substantially the form set
forth in Exhibit A, to be endorsed on each New Note authenticated and delivered by the Trustee.

91

 

     The Guarantee shall be executed on behalf of the Guarantor by any one of the Guarantor’s Chief
Executive Officer, Chief Operating Officer, President, Chief Financial Officer, Chief Credit
Officer, Chief Legal Officer, Managing Director, Chief Accounting Officer, any Vice President
(whether or not designated by a number or numbers or word or words added before or after the title
“Vice President”), Secretary or Controller or other person duly authorized by Member Action on
behalf of the Guarantor. The signature of any or all of these persons on the Guarantee may be
manual or facsimile.

     A Guarantee bearing the manual or facsimile signature of individuals who were at any time the
proper officers of the Guarantor shall bind the Guarantor, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and delivery of the New
Note on which the Guarantee is endorsed or did not hold such offices at the date of the Guarantee.

     The delivery of any New Note by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee endorsed thereon on behalf of the Guarantor.

     Section 15.03 . Release of Guarantee. Notwithstanding anything in this Article 15 to the
contrary, concurrently with the payment in full of (i) the principal of and Interest on the New
Notes and (ii) all other obligations of the Company under this Indenture, the Guarantor shall be
released from and relieved of its obligations under this Article 15. Upon the delivery by the
Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that the
transaction giving rise to the release of the Guarantee was made by the Company in accordance with
the provisions of this Indenture and the New Notes, the Trustee shall execute any documents
reasonably required in order to evidence the release of the Guarantor from its obligations under
the Guarantee. If any of the obligations to pay the principal of and Interest on the New Notes and
all other obligations of the Company are revived and reinstated after the termination of the
Guarantee, then all of the obligations of the Guarantor under the Guarantee shall be revived and
reinstated as if the Guarantee had not been terminated until such time as the principal of and
Interest on the New Notes are paid in full, and the Guarantor shall enter into an amendment to the
Guarantee, reasonably satisfactory to the Trustee, evidencing such revival and reinstatement.

ARTICLE 16

Subordination of the New Notes

Section 16.01 . Agreement of Subordination.

     The Company covenants and agrees, and each Noteholder issued hereunder by its acceptance
thereof likewise covenants and agrees, that all New

92

 

Notes shall be issued subject to the provisions
of this Article 16; and each Person holding any New Note, whether upon original issue or upon
transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions.

     The payment of the principal of, and the cash portion of the Conversion Obligation as set
forth in Section 14.03, and any Interest on, all New Notes (including, but not limited to, the
Fundamental Change Repurchase Price with respect to the New Notes subject to purchase in accordance
with pursuant to Section 3.05) issued hereunder shall, except to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the prior payment in
full, in cash or other payment satisfactory to the holders of all of the Company’s other existing
and future Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred.
The New Notes shall rank senior in right of payment to all of the Company’s Indebtedness, whether
outstanding at the date of this Indenture or thereafter incurred, that provides for its
subordination to the New Notes, including any guarantee issued by the Company of Indebtedness
incurred by the Guarantor in connection with the TP Securities outstanding as of the date of this
Indenture. The New Notes shall rank equal in right of payment to all of the Company’s
Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred, which
provides for equal ranking with the New Notes, including Indebtedness issued by the Company in
connection with the Contemporaneous Exchange Offer.

     No provision of this Article 16 shall prevent the occurrence of any default or Event of
Default hereunder.

Section 16.02 . Payments to Holders.

     (a) No payment shall be made with respect to the principal of (including any Redemption Price
or Repurchase Price pursuant to Article 3) and Interest on, the New Notes, except payments and
distributions made by the Trustee as permitted by the first or second paragraph of Section 16.07,
if:

     (i) a default in the payment of Senior Indebtedness occurs and is continuing beyond
any applicable period of grace (a “Payment Default”),

     (ii) the Company receives written notice of such Payment Default by the holders of
such Senior Indebtedness, or any trustee therefor, and

     (iii)
unless and until such Payment Default shall have been cured or waived
or shall have ceased to exist.

     Promptly upon receiving notice of a Payment Default, and subject to Section 16.07, the Company
shall deliver to the Trustee an Officers’ Certificate specifying with particularity such Payment
Default and further stating what action the Company has taken, is taking or proposes to take with
respect thereto. The Company hereby covenants and agrees that it shall resume payments on and

93

 

distributions in respect of the New Notes upon the date on which such Payment Default is cured or
waived or ceases to exist. Promptly upon becoming aware that a Payment Default has been cured or
waived or ceased to exist, and subject to Section 16.07, the Company shall deliver to the Trustee
an Officers’ Certificate specifying that a Payment Default no longer exists and that payments in
respect of principal (including any Redemption Price or Repurchase Price pursuant to Article 3 and
Interest (including, if any, Defaulted Interest) shall resume.

     (b) In the event of a bankruptcy, insolvency or other proceeding described in clause (k) or
(l) of the definition of Event of Default in Section 6.01 (each such event, if any, herein
sometimes referred to as a “Proceeding”), all Senior Indebtedness (including any interest thereon
accruing after the commencement of any such proceedings) of the Company shall first be paid in full
before any payment or distribution, whether in cash, securities or other property, shall be made to
any Noteholder on account thereof. Any payment or distribution, whether in cash, securities or
other property (other than securities of the Company or any other entity provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to the extent provided
in these subordination provisions with respect to the Indebtedness evidenced by the New Notes or
the Guarantee, to the payment of all Senior Indebtedness of the Company at the time outstanding and
to any securities issued in respect thereof under any such plan of reorganization or readjustment),
which would otherwise (but for these subordination provisions) be payable or deliverable in respect
of the New Notes shall be paid or delivered directly to the holders of Senior Indebtedness of the
Company in accordance with the priorities then existing among such holders until all Senior
Indebtedness (including any interest thereon accruing after the commencement of any Proceeding) of
the Company shall have been paid in full.

     (c) In the event of any Proceeding, after payment in full of all sums owing with respect to
Senior Indebtedness of the Company, the Noteholders, together with the holders of any obligations
of the Company ranking pari passu with the New Notes, shall be entitled to be paid from the
remaining assets of the Company the amounts at the time due and owing on account of unpaid
principal of and any premium and Interest on the New Notes and such other obligations before any
payment or other distribution, whether in cash, property or otherwise, shall be made on account of
any equity or membership interests or any obligations of the Company ranking junior to the New
Notes and such other obligations. If, notwithstanding the foregoing, any payment or distribution
of any character or any security, whether in cash, securities or other property (other than
securities of the Company or any other entity provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the Indebtedness evidenced by the New Notes, to the
payment of all Senior Indebtedness of the Company at the time outstanding and to any securities
issued in respect thereof under any such

94

 

plan of reorganization or readjustment) shall be received
by the Trustee or any Noteholder in contravention of any of the terms hereof and before all Senior
Indebtedness of the Company shall have been paid in full, such payment or distribution or security
shall be received in trust for the benefit of, and shall be paid over or delivered and transferred
to, the holders of the Senior Indebtedness of the Company at the time outstanding in accordance
with the priorities then existing among such holders for application to the payment of all Senior
Indebtedness of the Company remaining unpaid, to the extent necessary to pay all such Senior
Indebtedness (including any interest thereon accruing after the commencement of any Proceeding) of
the Company in full. In the event of the failure of the Trustee or any Noteholder to endorse or
assign any such payment, distribution or security, each holder of Senior Indebtedness of the
Company is hereby irrevocably authorized to endorse or assign the same.

     (d) Upon any payment or distribution of assets of the Company referred to in this Article 16,
the Trustee and the Noteholders shall be entitled to conclusively rely upon any order or decree
entered by any court of competent jurisdiction in which such Proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for
the benefit of creditors, agent or other Person making such payment or distribution, delivered to
the Trustee or to the Noteholders, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 16.

     (e) The Trustee and the Noteholders, at the expense of the Company, shall take such reasonable
action (including the delivery of this Indenture to an agent for any holders of Senior Indebtedness
of the Company or consent to the filing of a financing statement with respect hereto) as may, in
the opinion of counsel designated by the holders of a majority in principal amount of the Senior
Indebtedness of the Company at the time outstanding, be necessary or appropriate to assure the
effectiveness of the subordination effected by these provisions.

     (f) The provisions of this Section 16.02 shall not impair any rights, interests, remedies or
powers of any secured creditor of the Company in respect of any security interest the creation of
which is not prohibited by the provisions of this Indenture.

     (g) The securing of any obligations of the Company, otherwise ranking on a parity with the New
Notes or the Guarantee or ranking junior to the New Notes or Guarantee, shall not be deemed to
prevent such obligations from
constituting, respectively, obligations ranking on a parity with the New Notes or the
Guarantee or ranking junior to the New Notes or the Guarantee.

95

 

     Section 16.03. Payment Permitted If No Default.

     Nothing contained in this Article 16 or elsewhere in this Indenture or in any of the New Notes
shall prevent (a) the Company, at any time, except during the pendency of the conditions described
in paragraph (a) of Section 16.02 or of any Proceeding referred to in Section 16.02, from making
payments at any time of principal of and any premium or Interest on the New Notes or (b) the
application by the Trustee of any monies deposited with it hereunder to the payment of or on
account of the principal of and any premium or Interest on the New Notes or the retention of such
payment by the Noteholders, if, at the time of such application by the Trustee, it did not have
knowledge (in accordance with Section 16.07 that such payment would have been prohibited by the
provisions of this Article 16, except as provided in Section 16.07.

     Section 16.04. Provisions Solely to Define Relative Rights.

     The provisions of this Article 16 are and are intended solely for the purpose of defining the
relative rights of the Noteholders on the one hand and the holders of Senior Indebtedness of the
Company on the other hand. Nothing contained in this Article 16 or elsewhere in this Indenture or
in the New Notes is intended to or shall (a) impair, as between the Company and the Noteholders,
the obligations of the Company, which are absolute and unconditional, to pay to the Noteholders the
principal of and any premium and Interest on the New Notes as and when the same shall become due
and payable in accordance with their terms, (b) affect the relative rights against the Company of
the Noteholders and creditors of the Company other than their rights in relation to the holders of
Senior Indebtedness of the Company or (c) prevent the Trustee or the Holder of any New Note from
exercising all remedies otherwise permitted by applicable law upon default under this Indenture,
including filing and voting claims in any Proceeding, subject to the rights, if any, under this
Article 16 of the holders of Senior Indebtedness of the Company to receive cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder.

     Section 16.05. Subrogation of New Notes.

     Subject to the payment in full of all amounts due or to become due on all Senior Indebtedness
of the Company, or the provision for such payment in cash or cash equivalents or otherwise in a
manner satisfactory to the holders of Senior Indebtedness of the Company, the Noteholders shall be
subrogated to the extent of the payments or distributions made to the holders of such Senior
Indebtedness pursuant to the provisions of this Article 16 (equally and ratably with the holders of
all Indebtedness of the Company that by its express terms is subordinated to Senior Indebtedness of
the Company to substantially the same extent as the New Notes are subordinated to the Senior
Indebtedness of the Company and are
entitled to like rights of subrogation by reason of any payments or distributions

96

 

made to
holders of such Senior Indebtedness of the Company) to the rights of the holders of such Senior
Indebtedness of the Company to receive payments and distributions of cash, property and securities
applicable to such Senior Indebtedness of the Company until the principal of and any premium and
interest on the New Notes shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of the Company of any cash, property or
securities to which the Noteholders or the Trustee would be entitled except for the provisions of
this Article 16, and no payments made pursuant to the provisions of this Article 16 to the holders
of Senior Indebtedness of the Company by Noteholders or the Trustee, shall, as among the Company,
its creditors other than holders of Senior Indebtedness of the Company, and the Noteholders, be
deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness
of the Company.

     Section 16.06. Authorization to Effect Subordination.

     Each Noteholder by his or her acceptance thereof authorizes and directs the Trustee on his or
her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the
subordination provided in this Article 16 and appoints the Trustee his or her attorney-in-fact for
any and all such purposes.

     Section 16.07. Notice to Trustee.

     (a) The Company shall give prompt written notice to a Responsible Officer of the Trustee of
any fact known to the Company that would prohibit the making of any payment to or by the Trustee in
respect of the New Notes. Notwithstanding the provisions of this Article 16 or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts
that would prohibit the making of any payment to or by the Trustee in respect of the New Notes,
unless and until a Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder of Senior Indebtedness or from any trustee, agent or representative
therefor; provided, that if the Trustee shall not have received the notice provided for in this
Section 16.07 at least two Business Days prior to the date upon which by the terms hereof any
monies may become payable for any purpose (including, the payment of the principal of and any
premium on or interest on any New Note), then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such monies and to
apply the same to the purpose for which they were received and shall not be affected by any notice
to the contrary that may be received by it within two Business Days prior to such date.

     (b) The Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself or herself to be a holder of Senior Indebtedness of the Company (or a
trustee, agent, representative or

97

 

attorney-in-fact therefor) to establish that such notice has been
given by a holder
of Senior Indebtedness of the Company (or a trustee, agent, representative or attorney-in-fact
therefor). In the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior Indebtedness of the Company
to participate in any payment or distribution pursuant to this Article 16, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness of the Company held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent to the rights of such
Person under this Article 16, and if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the right of such Person to receive
such payment.

     Section 16.08. Rights of Trustee as Holder of Senior Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article 16 with respect to any Senior Indebtedness of the Company that may at any time be held by
it, to the same extent as any other holder of Senior Indebtedness of
the Company, and nothing in this Indenture
shall deprive the Trustee of any of its rights as such holder.

     Section 16.09. No Waiver of Subordination Provisions.

     (a) No right of any present or future holder of any Senior Indebtedness of the Company to
enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by
any act or failure to act on the part of the Company or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or
be otherwise charged with.

     (b) Without in any way limiting the generality of paragraph (a) of this Section 16.09, the
holders of Senior Indebtedness of the Company may, at any time and from to time, without the
consent of or notice to the Trustee or the Noteholders, without incurring responsibility to such
Noteholders and without impairing or releasing the subordination provided in this Article 16 or the
obligations hereunder of such Noteholders to the holders of Senior Indebtedness of the Company, do
any one or more of the following:

     (i) change the manner, place or terms of payment or extend the time of payment of, or
renew or alter, such Senior Indebtedness, or otherwise amend or supplement in any manner
such Senior Indebtedness or any instrument evidencing the same or any agreement under
which such Senior Indebtedness is outstanding;

98

 

     (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing such Senior Indebtedness;

     (iii) release any Person liable in any manner for the payment of such Senior
Indebtedness; and

     (iv) exercise or refrain from exercising any rights against the Company and any other
Person.

     Section 16.10. Certain Conversions Deemed Payment.

     For the purposes of this Article 16 only, (1) the issuance and delivery of junior securities
upon conversion of New Notes in accordance with Section 14.03 shall not be deemed to constitute a
payment or distribution on account of the principal of, or premium, if any, the cash portion of the
principal of, if any, or Interest on, New Notes or on account of the purchase or other acquisition
of New Notes, and (2) the payment, issuance or delivery of cash (except in satisfaction of
fractional shares pursuant to Section 14.03), property or securities (other than junior securities)
upon conversion of a New Note shall be deemed to constitute payment on account of the principal of
such New Note. For the purposes of this Section 16.10, the term “junior securities” means (a)
shares of capital stock of any class or series of the Company or (b) securities of the Company
which are subordinated in right of payment to all Senior Indebtedness of the Company which may be
outstanding at the time of issuance or delivery of such securities to substantially the same extent
as, or to a greater extent than, the New Notes are so subordinated as provided in this Article 16.
Nothing contained in this Article 16 or elsewhere in this Indenture or in the New Notes is intended
to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness

benefit of, and shall be paid over or delivered and transferred to, the holders of the Senior
Indebtedness of the Guarantor at the time outstanding in accordance with the priorities then
existing among such holders for application to the payment of all Senior Indebtedness of the
Guarantor remaining unpaid, to the extent necessary to pay all such Senior Indebtedness (including
any interest thereon accruing after the commencement of any Proceeding) of the Guarantor in full.
In the event of the failure of the Trustee or any Noteholder to endorse or assign any such payment,
distribution or security, each holder of Senior Indebtedness of the Guarantor is hereby irrevocably
authorized to endorse or assign the same.

manner satisfactory to the holders of Senior Indebtedness of the Guarantor, the Noteholders shall
be subrogated to the extent of the payments or distributions made to the holders of such Senior
Indebtedness pursuant to the provisions of this Article 17 (equally and ratably with the holders of
all Indebtedness of the Guarantor that by its express terms is subordinated to Senior Indebtedness
of the Guarantor to substantially the same extent as the New Notes are subordinated to the Senior
Indebtedness of the Guarantor and are entitled to like rights of subrogation by reason of any
payments or distributions made to holders of such Senior Indebtedness) to the rights of the holders
of such Senior Indebtedness to receive payments and distributions of cash, property and securities
applicable to such Senior Indebtedness until the principal of and any premium and interest on the

Indebtedness of the Guarantor by Noteholders or the Trustee, shall, as among the Guarantor, its

104

 

     (a) The Guarantor shall give prompt written notice to a Responsible Officer of the Trustee of
any fact known to the Guarantor that would prohibit the making of any payment to or by the Trustee
in respect of the New Notes. Notwithstanding the provisions of this Article 17 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts that would prohibit the making of any payment to or by the Trustee in respect of the New
Notes, unless and until a Responsible Officer of the Trustee shall have received written notice
thereof from the Guarantor or a holder of Senior Indebtedness or from any trustee, agent or
representative therefor; provided, that if the Trustee shall not have received the notice provided
for in this Section 17.07 at least two Business Days prior to the date upon which by the terms

power and authority to receive such monies and to apply the same to the purpose for which they were
received and shall not be affected by any notice to the contrary that may be received by it within
two Business Days prior to such date.

     (b) The Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself or herself to be a holder of Senior Indebtedness of the Guarantor (or a
trustee, agent, representative or attorney-in-fact therefor) to establish that such notice has been
given by a holder of Senior Indebtedness of the Guarantor (or a trustee, agent, representative or
attorney-in-fact therefor). In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of
the Guarantor to participate in any payment or distribution pursuant to this Article 17, the
Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee
as to the amount of Senior Indebtedness of the Guarantor held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 17, and if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial determination as to
the right of such Person to receive such payment.

     The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article 17 with respect to any Senior Indebtedness of the Guarantor that may at any time be held by
it, to the same extent as any other holder of Senior Indebtedness of the Guarantor, and nothing in
this Indenture shall deprive the Trustee of any of its rights as such holder.

     Section 17.09. No Waiver of Subordination Provisions.

105

 

     (a) No right of any present or future holder of any Senior Indebtedness of the Guarantor to
enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by
any act or failure to act on the part of the Guarantor or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Guarantor with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or
be otherwise charged with.

Noteholders and without impairing or releasing the subordination provided in this Article 17 or the
obligations hereunder of such Noteholders to the holders of Senior Indebtedness of the
Guarantor, do any one or more of the following:

     (i) change the manner, place or terms of payment or extend the time of payment of, or

Indebtedness; and

     (iv) exercise or refrain from exercising any rights against the Guarantor and any
other Person.

     For the purposes of this Article 17 only, (1) the issuance and delivery of junior securities
upon conversion of New Notes in accordance with Section Section 14.03 shall not be deemed to
constitute a payment or distribution on account of the principal of, or premium, if any, the cash
portion of the principal of, if any, or Interest on, New Notes or on account of the purchase or
other acquisition of New Notes, and (2) the payment, issuance or delivery of cash (except in
satisfaction of fractional shares pursuant to Section 14.03), property or securities (other than
junior securities) upon conversion of a New Note shall be deemed to constitute payment on account
of the principal of such New Note. For the purposes of this Section 17.10, the term “junior
securities” means (a) shares of capital stock of any class or series of the Guarantor or (b)
securities of the Guarantor which are subordinated in right of payment to all Senior Indebtedness

substantially the same extent as, or to a greater extent than, the New Notes are so subordinated as
provided in this Article 17. Nothing contained in this Article 17 or elsewhere in this Indenture
or in the New Notes is intended to or shall impair, as among the Guarantor, its creditors other
than holders of Senior Indebtedness
of the Guarantor and the Noteholders, the right, which is
absolute and unconditional, of any Noteholder to convert New Notes in accordance with Article 14.

     Section 17.11. Article Applicable to Paying Agents.

     If at any time any Paying Agent other than the Trustee shall have been appointed by the
Guarantor and be then acting hereunder, the term “Trustee” as used in this Article 17 shall in such
case (unless the context otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as
fully for all intents and purposes as if such Paying Agent were named in this Article 17 in
addition to or in place of the Trustee.

     Section 17.12. Senior Indebtedness Entitled to Rely.

     The holders of Senior Indebtedness of the Guarantor shall have the right to rely upon this
Article 17, and no amendment or modification of the provisions contained herein shall diminish the
rights of such holders unless such holders shall have agreed in writing thereto.

     Section 17.13. Trustee Not Fiduciary for Holders of Senior Indebtedness.

     The Trustee, in its capacity as trustee under this Indenture, shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness of the Guarantor and shall not be liable to
any such holders if it shall in good faith mistakenly pay over or distribute to Noteholders or to
the Guarantor or to any other Person cash, property or securities to which any holders of Senior
Indebtedness of the Guarantor shall be entitled by virtue of this Article 17 or otherwise.

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 Noteholders as the names and addresses of such Noteholders 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 Section 7.02, Section 7.03, Section 7.04 and Section 8.03 and this Section
18.02 shall be applicable to any authenticating agent.

     Section 18.14. 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 18.15. Severability. In case any provision in this Indenture or in the New 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.

     Section 18.16. Tax Treatment. The parties agree to treat the issuance of the New Notes in
exchange for the Old Notes as constituting a significant modification of the Old Notes for U.S.
federal income tax purposes.

FORM OF REVERSE OF NEW NOTE

CAPITALSOURCE INC.

4% SENIOR SUBORDINATED CONVERTIBLE DEBENTURE DUE 2034

     This New Note is one of a duly authorized issue of New Notes of the Company, designated as its
Senior Subordinated Convertible Debentures due 2034 (herein called the “New Notes”), limited in
aggregate principal amount to $[330,000,000], issued and to be issued under and pursuant to an
Indenture dated as of March [     ], 2007 (herein called the “Indenture”), among the Company and
CapitalSource Finance LLC, as guarantor (herein called the “Guarantor”), and Wells Fargo Bank,
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 Guarantor and the
holders of the New Notes.

     In case an Event of Default shall have occurred and be continuing, the principal of and
accrued Interest on all New Notes may be declared by either the Trustee or the holders of not less
than 25% in aggregate principal amount of the New Notes then outstanding, and upon said declaration
shall 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 and the Trustee, with the consent of
the holders of at least a majority in aggregate principal amount of the New 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 New Notes; provided that no such supplemental
indenture shall (A) extend the Stated Maturity of any New Note, or (B) reduce the rate or extend
the time for payment of Interest thereon, or (C) reduce the principal amount thereof, or (D) reduce
any amount payable on redemption or repurchase thereof, or (E) impair the right of any holder to
institute suit for the payment thereof, or (F) make the principal thereof or Interest thereon
payable in any coin or currency other than that provided in the New Notes, or (G) affect the
obligation of the Company to redeem any New Note on a Redemption Date in a manner adverse to the
holders of New Notes, or (H) affect the obligation of the Company to repurchase any New Note upon
the happening of a Fundamental Change in a manner adverse to the holders of New Notes, or (I)
affect the obligation of the Company to repurchase any New Note on a Company Repurchase Date in a
manner adverse to the holders of New Notes, or (J) impair the right to convert the New Notes into
Common Stock subject to the

A-4

 

terms set
forth in the Indenture, including Section 14.08 thereof, or (K) reduce the number of
shares of Common Stock, the amount of cash or the amount of other property receivable upon
conversion, in each case, without the consent of the holder of each New Note so affected, or (L)
modify any of the provisions of Section 10.02 of the Indenture or Section 6.07 thereof, except to
increase any such percentage or to provide that certain other provisions of this Indenture cannot
be modified or waived without the consent of the holder of each New Note so affected, or (M) reduce
the quorum or voting requirements set forth in Article 9 of the Indenture or (N) reduce the
aforesaid percentage of New Notes, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of all New Notes then outstanding.
Subject to the provisions of the Indenture, the holders of a majority in aggregate principal amount
of the New Notes at the time outstanding may on behalf of the holders of all of the New Notes waive
any past default or Event of Default under the Indenture and its consequences except (A) a default
in the payment of Interest on or the principal of any of the New Notes, (B) a failure by the
Company to convert any New Notes into Common Stock, cash or a combination of cash and Common Stock
of the Company, (C) a default in the payment of the Redemption Price pursuant to Article 3 of the
Indenture, (D) a default in the payment of the Company Repurchase Price or Fundamental Change
Repurchase Price pursuant to Article 3 of the Indenture, or (E) a default in respect of a covenant
or provision of the Indenture which under Article 10 of the Indenture cannot be modified or amended
without the consent of the holders of each or all New Notes then outstanding or affected thereby.
Any such consent or waiver by the holder of this New 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 New Note and any New Notes which may be issued in exchange or substitution hereof,
irrespective of whether or not any notation thereof is made upon this New Note or such other New
Notes.

     No reference herein to the Indenture and no provision of this New Note or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and Interest on this New Note at the place, at the respective times, at the rate
and in the coin or currency herein prescribed.

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

     The New 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

A-5

 

any registration or exchange of New Notes, New Notes may be exchanged for a like aggregate
principal amount of New Notes of any other authorized denominations.

     At any time on or after July 15, 2011 and prior to maturity, the New Notes may be redeemed at
the option of the Company, in whole or in part, in cash or shares of Common Stock, or a combination
of cash and shares of Common Stock, upon mailing a notice of such redemption not less than 30 days
but not more than 60 days before the Redemption Date to the holders of New Notes at their last
registered addresses, all as provided in the Indenture, at a Redemption Price equal to 100% of the
principal amount of New Notes being redeemed plus accrued and unpaid Interest to, but excluding,
the Redemption Date; provided that if the applicable Redemption Date is 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 New Notes on the applicable Record Date instead of the holders
surrendering such New Notes for redemption on such date.

     In no event will any New Note be redeemable at the option of the Company before July 15, 2011.

     The Company may not give notice of any redemption of the New Notes if a default in the payment
of Interest on the New Notes has occurred and is continuing.

     The New 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 New Notes, each holder
shall have the right, at such holder’s option, to require the Company to repurchase this New Note
for cash, or subject to certain conditions, Common Stock, on a Fundamental Change Repurchase Date,
specified by the Company, which shall be no later than 30 Business Days after notice thereof, at a
Fundamental Change Repurchase Price equal to at least 100% of the principal amount thereof,
together with accrued Interest to, but excluding, the Fundamental Change Repurchase Date. The
Company shall mail to all holders of record of the New 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
day after the occurrence of such Fundamental Change. For a New Note to be so repurchased at the
option of the holder, the Company must receive at the office or agency of the Company maintained
for that purpose in accordance with the terms of the Indenture, such New Note with the form
entitled “Form of Fundamental Change Repurchase Notice” on the reverse thereof duly completed,
together with such New Note, duly endorsed for transfer at any time prior to the close of business
on the Business Day immediately preceding the Fundamental Change Repurchase Date.

A-6

 

     Subject to the terms and conditions of the Indenture, the Company shall become obligated to
repurchase, at the option of the holder, all or any portion of the New Notes held by such holder on
July 15, 2011, July 15, 2014, July 15, 2019, July 15, 2024, and July 15, 2029 in integral multiples
of $1,000 at a Company Repurchase Price of 100% of the principal amount, plus any accrued and
unpaid Interest on such New Note to but excluding the Company Repurchase Date. To exercise such
right, a holder shall deliver to the Company such New Note with the form entitled “Form of Company
Repurchase Election” on the reverse thereof duly completed, together with the New Note, duly
endorsed for transfer, at any time from the opening of business on the 20th Business Day prior to
such Company Repurchase Date until the close of business on the Business Day immediately preceding
the Company Repurchase Date, and shall deliver, or arrange for book-entry transfer of, the New
Notes to the Trustee (or other Paying Agent appointed by the Company) as set forth in the
Indenture.

     The Company Repurchase Price to be paid on any of July 15, 2011, July 15, 2014, July 15, 2019,
July 15, 2024 and July 15, 2029 shall be paid in cash and the Fundamental Change Repurchase Price
to be paid on any Fundamental Change Repurchase Date shall be paid in cash or Common Stock, subject
to the terms and conditions of the Indenture.

     Holders have the right to withdraw any Repurchase Election by delivering to the Trustee (or
other Paying Agent appointed by the Company) a written notice of withdrawal up to the close of
business on the Business Day immediately preceding the Repurchase Date, all as provided in the
Indenture.

     If money or Common Stock, if allowed under the Indenture, sufficient to pay the Repurchase
Price with respect to all New Notes or portions thereof to be repurchased as of any Repurchase Date
is deposited with the Trustee (or other Paying Agent appointed by the Company), then on and after
such Repurchase Date, such New Notes will cease to be outstanding, Interest will cease to accrue on
such New Notes (or portions thereof), and the holder thereof shall have no other rights as such
other than the right to receive the Repurchase Price upon surrender of such New Note.

     Subject to the occurrence of certain events and in compliance with the provisions of the
Indenture, prior to the Stated Maturity of the New Notes, the holder hereof has the right, at its
option, to convert each $1,000 principal amount of the New Notes into 37.9561 shares of the Common
Stock (a Conversion Price of approximately $26.35 per share), as such shares shall be constituted
at the date of conversion and subject to adjustment from time to time as provided in the Indenture,
upon surrender of this New Note with the form entitled “Form of Notice of Conversion” on the
reverse hereof duly completed, 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

A-7

 

Trust Office, and, unless the shares issuable on conversion are to be issued in the same name
as this New 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 convert the New Notes as specified
above in accordance with the Indenture.

     If the Company (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 convert a New Note into shares of
Common Stock will be changed into a right to convert it into the kind or amount of cash, securities
or other property receivable upon such event, in each case in accordance with the Indenture.

     No adjustment in respect of Interest on any New Note converted or dividends on any shares
issued upon conversion of such New Note will be made upon any conversion except as set forth in the
next sentence. If this New Note (or portion hereof) is surrendered for conversion during the
period from the close of business on any Record Date for the payment of Interest to the opening of
business on the immediately following Interest Payment Date, this New Note (or portion hereof being
converted) 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 converted; provided that no such payment shall be required (1) if the
Company has specified a Redemption Date that is after a Record Date and prior to the next Interest
Payment Date, (2) if the Company has specified a Repurchase Date following a Fundamental Change
that is after a Record Date and on or prior to the next Interest Payment Date or (3) to the extent
of any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect
to such New Note.

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

     A New 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 converted 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 New 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 New Notes of authorized denominations for an equal aggregate principal amount will be issued to
the

A-8

 

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 Guarantor, the Trustee, any authenticating agent, any Paying Agent, any
Conversion Agent and any Note Registrar may deem and treat the registered holder hereof as the
absolute owner of this New Note (whether or not this New 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 on or account of the principal hereof and the
Interest hereon, for the conversion hereof and for all other purposes, and neither the Company nor
the Trustee nor any other authenticating agent nor any Paying Agent nor other Conversion Agent nor
any Note Registrar shall be affected by any notice to the contrary. All payments made to or upon

Exhibit 10.1

SECOND AMENDMENT TO

CREDIT AGREEMENT

     THIS SECOND AMENDMENT TO CREDIT AGREEMENT (this “Second Amendment”) is entered into on
the 2nd day of March, 2007, but effective as of July 19, 2005 (the “Second Amendment
Closing Date”), by and among NRP (OPERATING) LLC, a Delaware limited liability company
(the “Borrower”), the banks and other financial institutions listed on the signature pages
hereto (together with each other person who becomes a Lender, collectively the “Lenders”)
including CITIBANK, N.A., a national banking association, as a Lender.

Preliminary Statement

     WHEREAS, Borrower, Administrative Agent and the Lenders are parties to that certain Credit
Agreement dated as of October 29, 2004, as amended by that certain First Amendment to Credit
Agreement dated as of November 9, 2005 (as same may be further amended, restated, increased and
extended, the “Credit Agreement”), under and subject to the terms of which the Lenders have
committed to make Revolving Loans and issue Letters of Credit to Borrower; and

     WHEREAS, Borrower has now requested that the Lenders modify the Credit Agreement to change
certain terms thereof; and

     WHEREAS, Borrower and the Lenders wish to execute this Second Amendment to evidence such
agreement;

     NOW, THEREFORE, in consideration of the mutual covenants herein contained and for other good
and valuable consideration, the receipt and adequacy of which are hereby acknowledged, Borrower and
the Lenders hereby agree as follows (all capitalized terms used herein and not otherwise defined
shall have the meanings as defined in the Credit Agreement):

     Section 1. Amendment to Section 6.16. Section 6.16 of the Credit Agreement is hereby
amended by deleting said Section in its entirety and replacing same with the following:

     “SECTION 6.16. Changes to the Note Purchase Agreement. The Borrower will not agree to, and
will not permit any amendment to the Note Purchase Agreement which would (i) make the
covenants in Section 10 of the Note Purchase Agreement more restrictive on the Borrower than
the corresponding financial covenants in Section 6.17 and Section 6.18
hereof or (ii) make the events of default in Section 11 of the Note Purchase Agreement more
restrictive on the Borrower than the Events of Default hereunder, in each case, without the
consent of the Required Lenders; provided, however, that in no event shall the covenants set
forth in Section 10 of the Note Purchase Agreement and the events of default set forth in
the Note Purchase Agreement as in effect on the date hereof be deemed to be more restrictive
than the corresponding covenants set

-1-

 

forth in Section 6.17 and Section 6.18 and the Events of Default hereunder.
If there is in existence a Default or Event of Default, the Borrower will not make any
voluntary prepayments of principal or interest on the notes outstanding under the Note
Purchase Agreement.”

     Section 2. Representations True; No Default. Borrower represents and warrants that:

     (a) this Second Amendment has been duly authorized, executed and delivered on its behalf; the
Credit Agreement, as amended hereby, together with the other Loan Documents to which Borrower is a
party, constitute valid and legally binding agreements of Borrower enforceable in accordance with
their terms;

     (b) the representations and warranties of Borrower contained in Article III of the Credit
Agreement are true and correct in all material respects on and as of the date hereof as though made
on and as of the date hereof; and

     (c) after giving effect to this Second Amendment, no Default or Event of Default under the
Credit Agreement has occurred and is continuing.

     Section 3. Expenses, Additional Information. Borrower shall pay to the Agent all
reasonable expenses incurred in connection with the execution of this Second Amendment, including
all reasonable expenses incurred in connection with any previous negotiation and loan
documentation. Borrower shall furnish to the Agent and Lenders all such other documents, consents
and information relating to Borrower as the Agent or any Lender may reasonably require to
accomplish the purposes hereof.

     Section 4. Effectiveness. This Second Amendment shall become effective on the Second
Amendment Closing Date when, and only when:

     (a) Borrower, Administrative Agent and the Lenders shall have executed and delivered to the
Administrative Agent a counterpart of this Second Amendment;

     (b) each of the representations and warranties made by the Borrower and each Guarantor in or
pursuant to the Loan Documents shall be true and correct in all material respects;

     (c) no event shall have occurred with respect to the Parent, the Borrower and its
Subsidiaries, taken as a whole, which, in the reasonable opinion of the Lenders, has had, or could
reasonably be expected to have, a Material Adverse Effect; and

     (d) Administrative Agent or any Lender or counsel to the Administrative Agent shall
receive such other instruments or documents as they may reasonably request.

     The Administrative Agent shall notify the Borrower and the Lenders of the Second Amendment
Closing Date upon the satisfaction of all of the foregoing conditions, and such notice shall be
conclusive and binding. Notwithstanding the foregoing, the rights and obligations of the parties
hereunder shall not become effective unless each of the foregoing conditions is satisfied (or
waived pursuant to Section 9.02 of the Credit Agreement) at or prior to

-2-

 

5:00 p.m., Houston, Texas time, on March 30, 2007 (and, in the event such conditions are not
so satisfied or waived, this Second Amendment shall be null and void and of no further force and
effect.

     Section 5. Miscellaneous Provisions.

     (a) From and after the execution and delivery of this Second Amendment, the Credit Agreement
shall be deemed to be amended and modified as herein provided, and except as so amended and
modified the Credit Agreement shall continue in full force and effect.

     (b) The Credit Agreement and this Second Amendment shall be read and construed as one and the
same instrument.

     (c) Any reference in any of the Loan Documents to the Credit Agreement shall be a reference to
the Credit Agreement as amended by this Second Amendment.

     (d) This Second Amendment shall be construed in accordance with and governed by the laws of
the State of New York and of the United States of America.

     (e) This Second Amendment may be signed in any number of counterparts and by different parties
in separate counterparts and may be in original or facsimile form, each of which shall be deemed an
original but all of which together shall constitute one and the same instrument.

     (f) The headings herein shall be accorded no significance in interpreting this Second
Amendment.

     Section 6. Binding Effect. This Second Amendment shall be binding upon and inure to
the benefit of Borrower, Lenders and the Agent and their respective successors and assigns, except
that Borrower shall not have the right to assign its rights hereunder or any interest herein.

     Section 7. Final Agreement of the Parties. This Second Amendment may not be
contradicted by evidence of prior, contemporaneous, or subsequent oral agreements. There are no
unwritten oral agreements between the parties hereto.

[The remainder of this page intentionally left blank.]

ACKNOWLEDGMENT OF GUARANTORS

     Each of the undersigned Guarantors hereby confirms that each Loan Document (as the same may be
amended or amended and restated, as the case may be, pursuant to and in connection with this Second
Amendment) to which it is a party or otherwise bound remains in full force and effect and will
continue to secure, to the fullest extent possible, the payment and performance of all
