delivered hereunder and duly issued by the Company, the valid obligations of the Company and the Guarantor, and to make this Indenture a valid and binding agreement of the Company, in accordance with
their and its terms, have been done. In addition, all things necessary to duly authorize the issuance of the Common Stock of the Company issuable upon the conversion of the Securities, and to duly

        For and in consideration of the premises and the purchase of the Securities by the Holders thereof, it is mutually covenanted and agreed, for the equal and
proportionate benefit of all Holders of the Securities, as follows:

otherwise;
and the terms "controlling" and "controlled" have meanings correlative to the foregoing.

respect of which the Average Sale Price is being calculated, or 

         (ii)  the
period (x) commencing on the date next succeeding the first public announcement of (a) the issuance of rights, warrants or options or (b) the
distribution, in each case, in respect of which the Average Sale Price is being calculated and (y) proceeding through the last full trading day prior to the Time of Determination with respect
to the rights, warrants or options or distribution in respect of which the Average Sale Price is being calculated (excluding days within such period, if any, which are not trading days), or 

        (iii)  the
period, if any, (x) commencing on the date next succeeding the Ex-Dividend Time with respect to the next preceding (a) issuance of

the last full trading day prior to the Time of Determination with respect to the rights, warrants or options or distribution in respect of which the Average Sale Price is being calculated (excluding
days within such period, if any, which are not trading days). 

        In
the event that the Ex-Dividend Time (or in the case of a subdivision, combination or reclassification, the effective date with respect thereto) with respect to a dividend,
subdivision, combination or reclassification to which Section 11.06(a), (b), (d) or (e) applies occurs during the period applicable for calculating
"Average Sale Price" pursuant to the definition in the preceding sentence, "Average Sale Price" shall be

1.05    Acts of Holders.    

        (a)   Any
request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and
evidenced by one or more instruments (which may take the form of an electronic writing or messaging or otherwise be in accordance with customary procedures of the Depositary or the Trustee) of
substantially similar tenor signed by such Holders in person or by their agent duly 

8

 

appointed
in writing (which may be in electronic form); and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the
Trustee and, when it is hereby expressly required, to the Company or the Guarantor. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent
(either of which may be in electronic form) shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee, the Company and the Guarantor, if made in the manner provided
in this Section. 

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

	(c)
	The

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

	(e)
	If
the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a
resolution of the Board of Directors, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other
Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or
after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite
proportion of outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the
outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture within six months after the record date.

endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication. 

        (a)    Global Securities.    Securities offered and sold within the United States to "qualified institutional buyers"
as defined in Rule 144A ("QIBs") in reliance on Rule 144A or in offshore transactions in reliance on Regulation S shall be issued,
initially in the form of a Global Security, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary and registered in the name of The Depository Trust
Company ("DTC") or the nominee thereof (such depositary, or any successor thereto, and any such nominee being hereinafter referred to as the
"Depositary") duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate Original Principal Amount of the
Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided. 

        (b)    Global Securities in General.    Except as provided in this Section 2.01, 2.06 or 2.12, owners of
beneficial interests in Global Securities will not be entitled to receive physical delivery of Certificated Securities. Each Global Security shall represent such of the outstanding Securities as shall
be specified therein and each shall provide that it shall represent the aggregate Original Principal Amount of outstanding Securities from time to time endorsed thereon and that the aggregate Original
Principal Amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions and conversions. 

        Any
adjustment of the aggregate Original Principal Amount of a Global Security to reflect the amount of any increase or decrease in the Original Principal Amount of outstanding
Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of
the Trustee and the Depositary. 

        (c)    Book-Entry Provisions.    This Section 2.01(c) shall apply only to Global Securities
deposited with or on behalf of the Depositary.

Trustee as custodian for such Depositary and (c) shall bear legends substantially to the following effect:

UNLESS
AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR THE INDIVIDUAL NOTES REPRESENTED HEREBY, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE
DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR
DEPOSITARY. 

UNLESS
THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE,
OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO
CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 

THIS
SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A ADOPTED UNDER THE SECURITIES ACT) OR
(B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S ADOPTED UNDER THE SECURITIES ACT; (2) AGREES THAT IT WILL NOT WITHIN
TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH SECURITY, EXCEPT (A) TO
THE ISSUER OR A SUBSIDIARY
THEREOF; (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A ADOPTED UNDER THE SECURITIES ACT (IF AVAILABLE); (C) TO PERSONS OTHER THAN U.S. PERSONS OUTSIDE THE UNITED
STATES IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 ADOPTED UNDER THE SECURITIES ACT OR ANOTHER AVAILABLE
EXEMPTION UNDER THE SECURITIES ACT (IF AVAILABLE), OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT; AND (3) AGREES THAT IT WILL, PRIOR TO ANY TRANSFER OF
THIS SECURITY WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY, FURNISH TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED PURSUANT
TO THE INDENTURE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION 

11

 

NOT
SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANING GIVEN TO THEM BY REGULATION S
UNDER THE SECURITIES ACT. IN ANY CASE, THE HOLDER HEREOF WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY HEDGING TRANSACTION WITH REGARD TO THIS SECURITY OR ANY COMMON STOCK ISSUABLE UPON CONVERSION
OF SUCH SECURITY, EXCEPT AS PERMITTED BY THE SECURITIES ACT. 

        (d)    Certificated Securities.    Securities not issued as interests in the Global Securities will be issued in
certificated form substantially in the form of Exhibit A-3 attached hereto. 

        (e)    U.S. Tax Legend.    All Securities shall bear the following legend: 

FOR
PURPOSES OF SECTIONS 1272, 1273 AND 1275 OF THE UNITED STATES INTERNAL REVENUE CODE OF 1986, AS AMENDED, THIS SECURITY IS ISSUED WITH ORIGINAL ISSUE DISCOUNT FOR UNITED STATES FEDERAL INCOME TAX
PURPOSES. THE ISSUE DATE IS MAY 20, 2003, AND THE YIELD TO MATURITY FOR PURPOSES OF ACCRUING ORIGINAL ISSUE DISCOUNT IS 6.625% PER ANNUM. 

        SECTION
2.02    Execution and Authentication.    The Notes shall be executed on behalf of the Company by any Officer
and the Guarantee endorsed thereon on behalf of the Guarantor by an Officer. The signature of the Officer of the Company on the Notes and of the Guarantor on the Guarantee may be manual or facsimile. 

        Securities
bearing the manual or facsimile signatures of an individual who was at the time of the execution of the Securities the proper Officer of the Company or the Guarantor, as the
case may be, shall bind the Company and the Guarantor, notwithstanding that such individual has ceased to hold such office prior to the authentication and delivery of such Securities or did not hold
such office at the date of authentication of such Securities. 

        No
Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication
substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory of the Trustee and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 

        The
Trustee shall authenticate and deliver Securities for original issue in an aggregate Original Principal Amount of up to $172,500,000 upon one or more Company Orders without any
further action by the Company. The aggregate Original Principal Amount of Securities outstanding at any time may not exceed the amount set forth in the foregoing sentence, except as provided in
Section 2.07. 

        The

12

 

        SECTION
2.03    Registrar, Paying Agent and Conversion Agent.    The Company shall maintain an office or agency where
Securities may be presented for registration of transfer or for exchange ("Registrar"), an office or agency where Securities may be presented for
purchase or payment ("Paying Agent"), an office or agency where all calculations in respect of the Securities shall be made
("Calculation Agent"), and an office or agency where Securities may be presented for conversion ("Conversion
Agent"). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars, one or more
additional paying agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent, including any named pursuant to Section 4.05. The term
Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.05. 

        The
Company shall enter into an appropriate agency agreement with any Registrar or co-registrar, Paying Agent or Conversion Agent (other than the Trustee). The agreement
shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a
Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate
compensation therefor pursuant to Section 7.07. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar. 

        The
Company initially appoints the Trustee as Calculation Agent, Registrar, Conversion Agent and Paying Agent in connection with the Securities. 

        SECTION
2.04    Paying Agent to Hold Money and Securities in Trust.    Except as otherwise provided herein, not later
than 10:00 a.m., New York City time, on each due date of payments in respect of any Security, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if
deposited on the due date) or Common Stock sufficient to make such payments when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the
Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money and Common Stock held by the Paying Agent for the making of payments in respect of the Securities and shall
notify the Trustee of any default by the Company in making any such payment. At any time during the continuance of any such default, the Paying Agent shall, upon the written request of the Trustee,
forthwith pay to the Trustee all money and Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall segregate the money and Common
Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and Common Stock held by it to the Trustee and to account for
any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money or Common Stock. 

        SECTION
2.05    Securityholder Lists.    The Trustee shall preserve in as current a form as is reasonably practicable
the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on
May 1 and November 1 a listing of Securityholders dated within 15 days of the date on which the list is furnished and at such other times as the Trustee 

13

 

may
request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. 

        SECTION
2.06    Transfer and Exchange.    

        (a)   Subject
to Section 2.12 hereof, upon surrender for registration of transfer of any Security, together with a written instrument of transfer satisfactory to the
Registrar duly executed by the Securityholder or such Securityholder's attorney duly authorized in writing, at the office or agency of the Company designated as Registrar or co-registrar
pursuant to Section 2.03, the Company shall execute, the Guarantor shall endorse and the Trustee upon receipt of a Company Order shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of any authorized denomination or denominations, of a like aggregate Original Principal Amount. The Company shall not charge a service charge for
any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the
registration of transfer or exchange of the Securities from the Securityholder requesting such registration of transfer or exchange. 

        Subject
to Section 2.12 hereof, at the option of the Holder, Securities may be exchanged for other Securities of any authorized denomination or denominations, of a like aggregate
Original Principal Amount, upon surrender of the Securities to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Securityholder or such
Securityholder's attorney duly authorized in writing, at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, the Guarantor shall endorse and the
Trustee upon receipt of a Company Order shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive. 

        The
Company shall not be required to make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be
redeemed in part, the portion thereof not to be redeemed) or any Securities in respect of which a Repurchase Notice or Fundamental Change Notice has been given and not withdrawn by the Holder thereof
in accordance with the terms of this Indenture (except, in the case of Securities to be purchased in part, the portion thereof not to be purchased) or any Securities for a period of 15 days
before the mailing of a notice of redemption of Securities to be redeemed. 

        (b)   Notwithstanding
any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a
Global Security, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Security shall be limited to transfers of such
Global Security in whole, or in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. 

        (c)   Successive
registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such registration shall be noted on
the register for the Securities. 

14

 

        (d)   Any
Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the
delivery by such Registrar of Securities upon registration of transfer or exchange of Securities. 

        (e)   No
Registrar shall be required to make registrations of transfer or exchange of Securities during any periods designated in the text of the Securities or in this
Indenture as periods during which such registration of transfers and exchanges need not be made. 

	(f)
	If
Securities are issued upon the registration of transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set forth on the form of
Security attached hereto as Exhibits A-1 and A-3 setting forth such restrictions (collectively, the "Legend"), or if a request
is made to remove the Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the
Registrar such satisfactory evidence, which shall include an Opinion of Counsel, as may be reasonably required by the Company and the Registrar, that neither the Legend nor the restrictions on
transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 or that such Securities are not "restricted" within the
meaning of Rule 144. Upon (i) provision of such satisfactory evidence or (ii) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a
registration statement that is effective at the time of such sale, the Trustee, upon receipt of a Company Order, shall authenticate and deliver a Security that does not bear the Legend. If the Legend
is removed from the face of a Security and the Security is subsequently held by an Affiliate of the Company, the Company shall use its reasonable best efforts to reinstate the Legend. 

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

        SECTION
2.07    Replacement Securities.    If (a) any mutilated Security is surrendered to the Trustee or
(b) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser within
the meaning of Article 8 of the Uniform Commercial Code (a "Protected Purchaser"), the Company shall execute, the Guarantor shall endorse and
upon receipt of a Company Order, the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of
like tenor and Original Principal Amount, bearing a number not contemporaneously outstanding. 

15

 

        In
case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3
hereof, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be. 

        Upon
the issuance of any new Securities under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the Trustee) in connection therewith. 

        Every
new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the
Company and the Guarantor, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder. 

        The
provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities. 

        SECTION
2.08    Outstanding Securities; Determinations of Holders' Action.    Securities outstanding at any time are
all the Securities authenticated by the Trustee, except for those cancelled by it, those paid pursuant to Section 2.10 and delivered to it for cancellation and those described in this
Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the
Holders of the requisite Original Principal Amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the
Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the
Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which a Responsible Officer of the Trustee actually knows to
be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination (including, without
limitation, determinations pursuant to Articles 6 and 9). 

        If
a Security is replaced pursuant to Section 2.07, the replaced Security ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to each of them
that the replaced Security is held by a Protected Purchaser unaware that such Security has been replaced, in which case the replacement security shall be deemed not to be outstanding. 

        If
the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day following the Repurchase Date or a Fundamental Change Redemption Date, or on
Stated Maturity, money or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then immediately after such Redemption Date, Repurchase Date, Fundamental Change
Redemption Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and the Accreted Principal Amount of such 

16

 

Securities,
shall cease to increase, and cash interest (if any) on such Securities shall cease to accrue; provided, that if such Securities are to be redeemed, notice of such redemption has been duly
given pursuant to this Indenture. 

        If
a Security is converted in accordance with Article 11, then from and after the time of conversion on the Conversion Date, such Security shall cease to be outstanding and the
Accreted Principal Amount of such Security shall cease to increase, and cash interest (if any) shall cease to accrue on such Security. 

        SECTION
2.09    Temporary Securities.    Pending the preparation of definitive Securities, the Company may execute,
the Guarantor may endorse and, upon Company Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in
any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities. 

        If
temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary
Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to
Section 2.03, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute, the Guarantor shall endorse and, upon Company
Order, the Trustee shall authenticate and deliver in exchange therefor a like Original Principal Amount of definitive Securities of authorized denominations. Until so exchanged the temporary
Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. 

        SECTION
2.10    Cancellation.    All Securities surrendered for payment, purchase by the Company pursuant to
Article 3, conversion, redemption or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled
by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated
and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new
Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 11. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the
Trustee. 

        SECTION
2.11    Persons Deemed Owners.    Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of
principal of the Security or the payment of any Redemption Price, Repurchase Price or Fundamental Change Redemption Price in respect thereof or cash interest thereon, for the purpose of conversion and
for all other purposes 

17

 

whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 

        SECTION
2.12    Global Securities.    

        (a)   Notwithstanding
any other provisions of this Indenture or the Securities, (A) transfers of a Global Security, in whole or in part, shall be made only in
accordance with Section 2.06 and Section 2.12(b)(i) below, (B) transfer of a beneficial interest in a Global Security for a Certificated Security shall comply with
Section 2.06 and Section 2.12(b)(i) below, and (C) transfers of a Certificated Security shall comply with Section 2.06 and Section 2.12(b)(ii) and
transfer of a Certificated Security for a Beneficial Interest in a Global Security shall comply with Section 2.06 and Section 2.12(b)(iii) below. 

        (b)    Transfer of Global Security.    A Global Security may not be transferred, in whole or in part, to any Person
other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that this Section 2.12(b)(i) shall not prohibit
any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the
Securities unless and until such Security has been registered in the name of such Person. Nothing in this Section 2.12(b)(i) shall prohibit or render ineffective any transfer of a
beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.12(b). 

        (i)    Restrictions on Transfer of a Beneficial Interest in a Global Security for a Certificated Security. A beneficial interest
in a Global Security may not be exchanged for a Certificated Security except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a request for transfer of a
beneficial interest in a Global Security in accordance with Applicable Procedures for a Certificated Security in the form satisfactory to the Trustee, together with: 

        (A)  so
long as the Securities are Restricted Securities, certification, in the form set forth in Exhibit B; 

        (B)  written
instructions to the Trustee to make, or direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to reflect a
decrease in the aggregate Original Principal Amount of the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be credited with
such decrease; and 

        (C)  if
the Company or Registrar so requests, an Opinion of Counsel or other evidence reasonably satisfactory to them as to the compliance with the restrictions set forth in
the Legend, 

then
the Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate Original
Principal Amount of Securities represented by the Global Security to be decreased by the aggregate Original Principal Amount of the Certificated Security 

18

 

to
be issued, shall authenticate and deliver such Certificated Security and shall debit or cause to be debited to the account of the Person specified in such instructions a beneficial interest in the
Global Security equal to the Original Principal Amount of the Certificated Security so issued. 

        (ii)   Transfer and Exchange of Certificated Securities. When Certificated Securities are presented to the Registrar with a
request: 

        (x)   to
register the transfer of such Certificated Securities; or 

        (y)   to
exchange such Certificated Securities for an equal Original Principal Amount of Certificated Securities of other authorized denominations, 

the
Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Securities surrendered
for registration of transfer or exchange: 

        (A)  shall
be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing; and 

        (B)  so
long as such Securities are Restricted Securities, such Securities are being transferred or exchanged pursuant to an effective registration statement under the
Securities Act or, if being transferred pursuant to clause (1), (2) or (3) below, are accompanied by the additional information and documents specified in each clause, as
applicable: 

        (1)   if
such Certificated Securities are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such
Holder to that effect; or 

        (2)   if
such Certificated Securities are being transferred to the Company, a certification to that effect; or 

        (3)   if
such Certificated Securities are being transferred pursuant to an exemption from registration (i) a certification to that effect (in the form set forth in
Exhibit B, if applicable) and (ii) if the Company or Registrar so requests, an opinion of counsel or other evidence reasonably satisfactory to them as to the compliance with the
restrictions set forth in the Legend. 

        (iii)  Restrictions on Transfer of a Certificated Security for a Beneficial Interest in a Global Security. A Certificated
Security may not be exchanged for a beneficial interest in a Global Security except upon satisfaction of the requirements set forth below. 

19

 

Upon
receipt by the Trustee of a Certificated Security, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 

        (A)  so
long as the Securities are Restricted Securities, certification, in the form set forth in Exhibit B, that such Certificated Security is being transferred to a
QIB in accordance with Rule 144A; and 

        (B)  written
instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Security to
reflect an increase in the aggregate Original Principal Amount of the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be
credited with such increase, 

then
the Trustee shall cancel such Certificated Security and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and
the Registrar, the aggregate Original Principal Amount of Securities represented by the Global Security to be increased by the aggregate Original Principal Amount of the Certificated Security to be
exchanged, and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Security equal to the Original Principal Amount of
the Certificated Security so cancelled. If no Global Securities are then outstanding, the Company shall issue and the Trustee, upon receipt of a Company Order, shall authenticate a new Global Security
in the appropriate Original Principal Amount. 

        (c)   Subject
to the succeeding paragraph, every Security shall be subject to the restrictions on transfer provided in the Legend including the requirement of the delivery of
an Opinion of Counsel, if so provided. Whenever any Restricted Security is presented or surrendered for registration of transfer or for exchange for a Security registered in a name other than that of
the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit B, dated the date of such surrender and signed by the Holder of such Security, as
to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed
certificate. 

        (d)   The
restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective
registration statement under the Securities Act or transferred in compliance with Rule 144 or, if earlier, upon the expiration of the holding period applicable to sales thereof under
paragraph (k) of Rule 144. Any Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such
Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a
transfer in compliance with Rule 144, by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable to the Company, addressed
to the 

20

 

Company,
the Trustee and the Registrar and in form acceptable to the Company, to the effect that the transfer of such Security has been made in compliance with Rule 144), be exchanged for a new
Security, of like tenor and aggregate Original Principal Amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement
registering the Securities under the Securities Act. The Trustee and the Registrar shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the
aforementioned opinion of counsel or registration statement. 

        (e)   As
used in the preceding two paragraphs of this Section 2.12, the term "transfer" encompasses any sale, pledge, transfer, hypothecation or other disposition of
any Security. 

        (f)    The
provisions of clauses (1), (2), (3), (4) and (5) below shall apply only to Global Securities: 

        (1)   Notwithstanding
any other provisions of this Indenture or the Securities, except as provided in Section 2.12(b)(i), a Global Security shall not be exchanged in
whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for Securities
registered in the names of any person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for
such Global Security or such Depositary has ceased to be a "clearing agency" registered under the Exchange Act, and a successor Depositary is not
appointed by the Company within 90 days or (ii) the Company elects to discontinue use of the system of book-entry transfer through DTC (or any successor depositary). Any
Global Security exchanged pursuant to clause (i) of this sub-section shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (ii)
of this sub-section may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall
be a Global Security; provided that any such Security so issued that is registered in the name of a person other than the Depositary or a nominee thereof shall not be a Global Security. 

        (2)   Securities
issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an
aggregate Original Principal Amount equal to that of such Global Security 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 the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar.
With regard to any Global Security to be exchanged in part, either such Global 

21

 

Security
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 Security, the Original 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 deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 

        (3)   Subject
to the provisions of clause (5) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members (as defined
below) and persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Indenture or the Securities. 

        (4)   In
the event of the occurrence of any of the events specified in clause (1) above, the Company will promptly make available to the Trustee a reasonable supply of
Certificated Securities in definitive, fully registered form, without interest coupons. 

        (5)   Neither
any members of, or participants in, the Depositary (collectively, the "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 Security registered in the name of the Depositary or any nominee thereof, or under any such
Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Guarantor, the Trustee and any agent of the Company or the Trustee as the absolute owner and
holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing 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 holder of any Security. 

        SECTION
2.13    CUSIP Numbers.    The Company in issuing the Securities may use "CUSIP" numbers (if then generally in
use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the
Securities, 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 numbers.

ARTICLE 3    
    
    REDEMPTION AND PURCHASES    
    

        SECTION
3.01    Right to Redeem; Notices to Trustee.    The Company, at its option, may redeem the Securities in
accordance with the provisions of paragraphs 6 and 8 of the Securities. Prior to May 15, 2010, the Company cannot redeem the Securities. Beginning on May 15, 2010, the Company may redeem
the Securities for cash in whole at any time, or in part from time to time. If the Company elects to redeem Securities pursuant to paragraph 6 of the Securities, it shall notify the Trustee in
writing of the Redemption Date, the Original Principal Amount of Securities to be redeemed, the Redemption Price and the amount of accrued and unpaid cash interest, if any, payable on the Redemption
Date. 

        The
Company shall give the notice to the Trustee provided for in this Section 3.01 by a Company Order, at least 45 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee). If fewer than all the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which
record date shall not be less than ten days after the date of notice to the Trustee. 

        SECTION
3.02    Selection of Securities to Be Redeemed.    If less than all the Securities are to be redeemed, the
Trustee shall select the Securities to be redeemed pro rata or by lot or by any other method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any
stock exchange on which the Securities are then listed). The Trustee shall make the selection at least 30 days but not more than 60 days before the Redemption Date from outstanding
Securities not previously called for redemption. 

        Securities
and any portions thereof that the Trustee selects shall be in Original Principal Amounts of $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply
to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be
redeemed. 

        If
any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted
portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be
treated by the Trustee as outstanding for the purpose of such selection. 

        SECTION
3.03    Notice of Redemption.    At least 30 days but not more than 60 days before a Redemption
Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed. 

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

        (1)   the
Redemption Date; 

23

 

        (2)   the
Redemption Price and accrued and unpaid cash interest, if any, payable on the Redemption Date; 

        (3)   the
Conversion Rate; 

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

        (5)   that
Securities called for redemption may be converted at any time before the close of business on the second Business Day immediately preceding the Redemption Date,
even if not otherwise convertible at such time; 

        (6)   that
Holders who want to convert Securities must satisfy the requirements set forth in paragraph 9 of the Securities; 

        (7)   that
Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and accrued and unpaid cash interest, if any; 

        (8)   if
fewer than all the outstanding Securities are to be redeemed, the certificate number and Original Principal Amounts of the particular Securities to be redeemed; 

        (9)   that,
unless the Company defaults in making payment of such Redemption Price and any cash interest which is due and payable, the Accreted Principal Amount will cease to
increase and cash interest (if any) will cease to accrue on and after the Redemption Date; 

        (10) the
CUSIP number of the Securities; and 

        (11) any
other information the Company wants to present. 

        At
the Company's request, the Trustee shall give the notice of redemption to Holders in the Company's name and at the Company's expense, provided that the Company makes such request at
least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date such notice of redemption must be mailed. 

        SECTION
3.04    Effect of Notice of Redemption.    Once notice of redemption is given, Securities called for
redemption become due and payable on the Redemption Date and at the Redemption Price (together with accrued and unpaid cash interest, if any, to but not including the date of redemption) stated in the
notice except for Securities which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price (together
with accrued and unpaid cash interest, if any, to but not including the date of redemption) stated in the notice. 

        SECTION
3.05    Deposit of Redemption Price.    Prior to 10:00 a.m. (New York City time), on any Redemption
Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to
pay the Redemption Price of, and any accrued and unpaid 

24

 

interest
to but not including the date of redemption with respect to, all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which on or prior
thereto have been delivered by the Company to the Trustee for cancellation or have been converted. The Paying Agent shall as promptly as practicable return to the Company any money not required for
that purpose because of conversion of Securities pursuant to Article 11. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such
trust. 

        SECTION
3.06    Securities Redeemed in Part.    Upon surrender of a Security that is redeemed in part, the Company
shall execute, the Guarantor shall endorse and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in Original Principal Amount to the
unredeemed portion of the Security surrendered. 

        SECTION
3.07    Conversion Arrangement on Call for Redemption.    In connection with any redemption of Securities, the
Company may arrange for the purchase and conversion of any Securities called for redemption by an agreement with one or more investment banks or other purchasers to purchase such Securities by paying
to the Trustee in trust for the Securityholders, on or prior to 10:00 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 Securities, is not less than the Redemption Price of, and any accrued and unpaid interest with respect to, such Securities. Notwithstanding anything to the contrary
contained in this Article 3, the obligation of the Company to pay the Redemption Prices of such Securities 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 Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent
permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 11 surrendered by such purchasers for conversion, all as of
immediately prior to the close of business on the second Business Day prior to the Redemption Date, subject to payment of the above amount as aforesaid. The Trustee shall hold and pay to the Holders
whose Securities 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
Securities. Without the Trustee's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Securities 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 Securities 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. 

        SECTION
3.08    Repurchase of Securities at Option of the Holder.    

        (a)   Securities
shall be purchased by the Company pursuant to the terms of the Securities at the option of the Holder on May 15, 2010, May 15, 2013 and
May 15, 2018 (each, a "Repurchase Date"), at a purchase price of 100% of the Accreted Principal Amount plus any accrued and unpaid interest (the
"Repurchase Price"), in each case, to, but excluding, such 

25

 

Repurchase
Date, subject to the provisions of Section 3.09. Beginning May 15, 2010, the Accreted Principal Amount of a Security will be equal to the Original Principal Amount of $1,000
increased daily by the rate of 6.625% per year. Repurchases of Securities under this Section 3.08 shall be made, at the option of the Holder thereof, upon: 

        (1)   delivery
to the Paying Agent by a Holder of a written notice (a "Repurchase Notice") during the period beginning at any
time from the opening of business on the date that is 20 Business Days prior to the applicable relevant Repurchase Date until the close of business on the third Business Day prior to such Repurchase
Date stating: 

        (A)  the
certificate numbers of the Securities which the Holder will deliver to be purchased, 

        (B)  the
portion of the Original Principal Amount of the Securities which the Holder will deliver to be purchased, which portion must be an Original Principal Amount of
$1,000 or an integral multiple thereof, 

        (C)  that
such Security shall be purchased as of the Repurchase Date pursuant to the terms and conditions specified in paragraph 7 of the Securities and in this
Indenture, and 

        (D)  in
the event the Company elects, pursuant to Section 3.09, to pay the Repurchase Price to be paid as of such Repurchase Date, in whole or in part, in shares of
Common Stock but such portion of the Repurchase Price shall ultimately be payable to such Holder entirely in cash because any of the conditions to payment of the Repurchase Price in Common Stock is
not satisfied prior to the close of business on such Repurchase Date, as set forth in Section 3.09(c), whether such Holder elects (i) to withdraw such Repurchase Notice as to some or all
of the Securities to which such Repurchase Notice relates (stating the Original Principal Amount and certificate numbers of the Securities as to which such withdrawal shall relate), or (ii) to
receive cash in respect of the entire Repurchase Price for all Securities (or portions thereof) to which such Repurchase Notice relates; and 

        (2)   delivery
or book-entry transfer of the Securities to Paying Agent at any time after delivery of the applicable Repurchase Notice (together with all necessary
endorsements) at the office of the Paying Agent, such delivery being a condition to receipt by the Holder of the Repurchase Price therefor; provided
that such Repurchase Price shall be so paid pursuant to this Section 3.08 only if the Security so delivered to Paying Agent shall conform in all respects to the description thereof in the
related Repurchase Notice. 

        If
the Company has elected to pay the Repurchase Price in whole or in part in shares of Common Stock, but is unable to deliver the shares of Common Stock, a Holder, in such Holder's
Repurchase Notice and in any written notice of withdrawal delivered by such Holder 

26

 

pursuant
to the terms of Section 3.10, may elect to withdraw the Repurchase Notice or to receive cash. If a Holder fails to indicate in its Repurchase Notice its election to receive cash or
Common Stock, the Holder shall be deemed to have elected to receive cash in respect of the entire Repurchase Price for all Securities subject to such Repurchase Notice. 

        The
Company shall purchase from the Holder thereof, pursuant to this Section 3.08, a portion of a Security, if the Original Principal Amount of such portion is $1,000 or an
integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security. 

        Any
purchase by the Company contemplated pursuant to the provisions of this Section 3.08 shall be consummated by the delivery of the consideration to be received by the Holder
promptly following the later of the Repurchase Date and the time of the book-entry transfer or delivery of the Security. 

        Notwithstanding
anything herein to the contrary, any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 3.08 shall have the right to withdraw
such Repurchase Notice at any time prior to the close of business on the Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.10. 

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

        SECTION
3.09    Company's Right to Elect Manner of Payment of Repurchase Price.    

        (a)   The
Securities to be repurchased on any Repurchase Date pursuant to Section 3.08 may be paid for, in whole or in part, at the election of the Company, in cash or
Common Stock or any combination of cash and Common Stock, subject to the conditions set forth in Sections 3.09(c) and (d). The Company shall designate, in the Company Repurchase Notice delivered
pursuant to Section 3.09(d), whether the Company will repurchase the Securities for cash or shares of Common Stock, or, if a combination thereof, the percentages of the Repurchase Price of
Securities in respect of which it will pay in cash or shares of Common Stock; provided that the Company will pay cash for fractional interests in shares of Common Stock. For purposes of determining
the existence of potential fractional interests, all Securities subject to repurchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be
presented). Each Holder whose Securities are repurchased pursuant to Section 3.08 shall receive the same percentage of cash or shares of Common Stock in payment of the Repurchase Price for such
Securities, except with regard to the payment of cash in lieu of fractional shares of Common Stock. The Company may not change its election with respect to the consideration (or components or
percentages of components thereof) to be paid once the Company has given its Company Repurchase Notice to Holders except pursuant to Section 3.09(c) in the event of a failure to satisfy, prior
to the close of business on the Business Day immediately preceding the Repurchase Date, any condition to the payment of the Repurchase Price, in whole or in part, in shares of Common Stock. 

27

 

        At
least three Business Days before each Company Repurchase Notice Date, the Company shall deliver an Officers' Certificate to the Trustee specifying: 

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

        (ii)   the
information required by Section 3.09(d) in the Company Repurchase Notice, 

        (iii)  if
the Company elects to pay the Repurchase Price, or a specified percentage thereof, in shares of Common Stock, that the conditions to such manner of payment set
forth in Section 3.09(c) have been or will be complied with, and 

        (iv)  whether
the Company desires the Trustee to give the Company Repurchase Notice required by Section 3.09(d). 

        (b)   At
the option of the Company, the Repurchase Price of Securities in respect of which a Repurchase Notice pursuant to Section 3.08 has been given, or a specified
percentage thereof, may be paid by the Company with cash. The Company Repurchase Notice, as provided in Section 3.09(d), shall be sent to Holders not less than 20 Business Days prior to such
Repurchase Date (the "Company Repurchase Notice Date"). 

        (c)   At
the option of the Company, the Repurchase Price of Securities in respect of which a Repurchase Notice pursuant to Section 3.08 has been given, or a specified
percentage thereof, may be paid by the Company by the issuance of a number of shares of Common Stock equal to the quotient obtained by dividing (i) the portion of the Repurchase Price to be
paid in shares of Common Stock by (ii) 97.5% of the average of the Closing Sale Price of the shares of Common Stock for the five-trading day period immediately preceding but ending
on the third Business Day prior to the applicable Repurchase Date, appropriately adjusted to take into account the occurrence, during the period commencing on the first of the trading days during the
five-trading day period and ending on the Repurchase Date, of any event described in Section 11.14, subject to the next succeeding paragraph. 

        The
Company will not issue fractional shares of Common Stock in payment of the Repurchase Price. Instead, the Company will pay cash based on the Closing Sale Price as of the applicable
Repurchase Date for all fractional shares. It is understood that if a Holder elects to have more than one Security purchased, the number of shares of Common Stock shall be based on the aggregate
Original Principal Amount of Securities to be purchased. 

        If
the Company elects to purchase the Securities by the issuance of shares of Common Stock or in any combination of cash and Common Stock, the Company Repurchase Notice, as provided in
Section 3.09(d), shall be sent to the Holders not later than the Company Repurchase Notice Date. 

        The
Company's right to exercise its election to purchase Securities through the issuance of shares of Common Stock shall be conditioned upon: 

28

 

        (i)    the
Company's giving a timely Company Repurchase Notice containing an election to purchase all or a specified percentage of the Securities with shares of Common Stock as
provided herein; 

        (ii)   the
registration of such shares of Common Stock under the Securities Act of 1933, as amended (the "Securities Act"), and
Securities Exchange Act of 1934, as amended (the "Exchange Act"), if required; 

        (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 

        (v)   the
receipt by the Trustee of an (A) Officers' Certificate stating that the terms of the issuance of the shares of Common Stock are in conformity with this
Indenture, (B) an Opinion of Counsel to the effect that the shares of Common Stock to be issued by the Company in payment of the Repurchase Price in respect of the Securities have been duly
authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Repurchase Price in respect of the Securities, will be validly issued, fully paid and
non-assessable and, to the best of such counsel's knowledge, free from preemptive rights under applicable state law or known material contracts and (c) an Officer's 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 Original Principal Amount of Securities and the Closing 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 third Business Day prior to the applicable Repurchase Date. If
the foregoing conditions are not satisfied prior to the close of business on the last day prior to the Repurchase Date and the Company has elected to repurchase the Securities through the issuance of
shares of Common Stock, the Company shall pay the entire Repurchase Price of the Securities in cash. 

        Promptly
after determination of the actual number of shares of Common Stock to be issued upon repurchase of Securities, 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 website or through such other public medium as the
Company may use at that time. 

        (d)   In
connection with any repurchase of Securities, the Company shall, no less than 20 Business Days prior to each Repurchase Date, give notice to Holders (with a copy to 

29

 

the
Trustee) setting forth information specified in this Section 3.09(d) (the "Company Repurchase Notice"). 

        Each
Company Repurchase Notice shall: 

        (1)   state
the Repurchase Price and the Repurchase Date to which the Company Repurchase Notice relates; 

        (2)   state
whether the Repurchase Price will be paid in cash, shares of Common Stock or a combination thereof, specifying the percentage of each; 

        (3)   if
shares of Common Stock will be used to pay all or part of the Repurchase Price, state: 

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

        (b)   that
Holders of the Securities 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; 

        (4)   include
a form of Repurchase Notice; 

        (5)   the
Conversion Rate; 

        (6)   state
the name and address of the Conversion Agent; 

        (7)   state
that Securities must be surrendered to the Paying Agent to collect the Repurchase Price; 

        (8)   if
the Securities are then convertible, state that Securities as to which a Repurchase Notice has been given may be converted only if the Repurchase Notice is withdrawn
in accordance with the terms of this Indenture; and 

        (9)   state
the CUSIP number of the Securities. 

Company
Repurchase Notices may be given by the Company or, at the Company's request, the Trustee shall give such Company Repurchase Notice in the Company's name and at the Company's expense. 

        (e)   All
shares of Common Stock delivered upon repurchase of the Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully
paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim created by the Company. 

        (f)    If
a Holder of a repurchased Security 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 

30

 

requests
the Common Stock to be issued in a name other than the Holder's name. The Paying Agent 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 Paying Agent 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. 

        (g)   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 Securities. 

        SECTION
3.10    Effect of Repurchase Notice.    Upon receipt by the Paying Agent of the Repurchase Notice specified in
Section 3.08, the Holder of the Security in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is validly withdrawn) thereafter be entitled to receive solely
the Repurchase Price with respect to such Security. Such Repurchase Price shall be paid to such Holder, subject to receipt of funds and/or Securities by the Paying Agent, promptly following the later
of (x) the Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in Section 3.08) and (y) the time of delivery of such Security to the Paying
Agent by the Holder thereof in the manner required by Section 3.08. Securities in respect of which a Repurchase Notice has been given by the Holder thereof may not be converted pursuant to
Article 11 hereof on or after the date of the delivery of such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn. 

        A
Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Repurchase Notice at any time prior to
the close of business on the Repurchase Date, specifying: 

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

        (2)   the
Original Principal Amount of the Security with respect to which such notice of withdrawal is being submitted, and 

        (3)   the
Original Principal Amount, if any, of such Security which remains subject to the original Repurchase Notice and which has been or will be delivered for purchase by
the Company. 

        A
written notice of withdrawal of a Repurchase Notice may be in the form set forth in the preceding paragraph or may be in the form of a conditional withdrawal contained in a Repurchase
Notice pursuant to the terms of Section 3.08(a)(1)(D). 

        SECTION
3.11    Deposit of Repurchase Price.    Prior to 10:00 a.m. (New York City Time) on the Business Day
following the Repurchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and
hold in trust as provided in Section 2.04) an amount of 

31

 

cash
(in immediately available funds if deposited on such Business Day) or Common Stock, if permitted hereunder, sufficient to pay the aggregate Repurchase Price of all the Securities or portions
thereof that are to be purchased as of the Repurchase Date. 

        As
soon as practicable after the Repurchase Date the Company shall deliver to each Holder entitled to receive shares of Common Stock through the Paying Agent, a certificate for the
number of full shares of Common Stock issuable in payment of the Repurchase Price and cash in lieu of any fractional interests. The person in whose name the certificate for the shares of Common Stock
is registered shall be treated as a Holder of record of Common Stock on the Business Day following the Repurchase
Date. No payment or adjustment will be made for dividends on the shares of Common Stock the record date for which occurred on or prior to the Repurchase Date. 

        SECTION
3.12    Securities Repurchased in Part.    Upon presentation of any Security repurchased only in part, the
Company shall execute, the Guarantor shall endorse and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Security or
Securities, of any authorized denomination, in aggregate Original Principal Amount equal to the unrepurchased portion of the Securities presented. 

        SECTION
3.13    Repayment to the Company.    The Paying Agent shall return to the Company any cash or shares of Common
Stock that remain unclaimed, together with interest or dividends, if any, thereon, held by them for the payment of the Repurchase Price; provided that to the extent that the aggregate amount of cash
or shares of Common Stock deposited by the Company pursuant to Section 3.11 exceeds the aggregate Repurchase Price of the Securities or portions thereof which the Company is obligated to
purchase as of the Repurchase Date then, unless otherwise agreed in writing with the Company, promptly after the Business Day following the Repurchase Date, the Paying Agent shall return any such
excess to the Company together with interest or dividends, if any, thereon. 

        SECTION
3.14    Redemption of Securities at Option of the Holder upon Fundamental Change.    

        (a)   If
there shall occur a Fundamental Change at any time prior to the Stated Maturity of the Securities, then each Securityholder shall have the right, at such Holder's
option, to require the Company to redeem all of such Holder's Securities, or any portion thereof that is a multiple of $1,000 Original Principal Amount, on the date (the
"Fundamental Change Redemption Date") that is thirty (30) days after the date of the Fundamental Change Notice (as defined in
Section 3.14(b)) of such Fundamental Change (or, if such 30th day is not a Business Day, the next succeeding Business Day) at a redemption price (the "Fundamental Change
Redemption Price") equal to 100% of the Accreted Principal Amount thereof, together with accrued interest to, but excluding, the Fundamental Change Redemption Date; provided
that if such Fundamental Change Redemption Date is an Interest Payment Date, then the interest payable on such Interest Payment Date shall be paid to the Holders of record of the Securities on the
applicable Regular Record Date instead of the Holders surrendering the Securities for redemption on such date. Beginning May 15, 2010, the Accreted Principal Amount of a Security 

32

 

will
be equal to the Original Principal Amount of $1,000 increased daily by the rate of 6.625% per year. 

        Upon
presentation of any Security redeemed in part only, the Company shall execute, the Guarantor shall endorse and, upon Company's Order, the Trustee shall authenticate and make
available for delivery to the Holder thereof, at the expense of the Company, a new Security or Securities, of authorized denominations, in aggregate Original Principal Amount equal to the unredeemed
portion of the Securities presented. 

        A
"Fundamental Change" means the occurrence of any transaction or event (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization or otherwise) in connection with which all or substantially all of the Common Stock shall be exchanged for, converted into,
acquired for or constitutes solely the right to receive consideration which is not all or substantially all common stock that is (or, upon consummation of or immediately following such transaction or
event, which will be) listed on a United States national securities exchange or approved (or, upon consummation of or immediately following such transaction or event, which will be approved) for
quotation on the Nasdaq National Market or any similar United States system of automated dissemination of quotations of securities prices. 

        (b)   On
or before the tenth day after the occurrence of a Fundamental Change, the Company or at its written request (which 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 in writing to a shorter period), the Trustee, in the name of and
at the expense of the Company, shall mail or cause to be mailed to all Holders of record on the date of the Fundamental Change a notice (the "Fundamental Change
Notice") of the occurrence of such Fundamental Change and of the redemption right at the option of the Holders arising as a result thereof. Such notice shall be mailed in the
manner and with the effect set forth in Section 3.03 (without regard for the time limits set forth therein). If the Company shall give such notice, the Company shall also deliver a copy of the
Fundamental Change Company Notice to the Trustee at such time as it is mailed to Securityholders. Concurrently with the mailing of any Fundamental Change Notice, the Company shall issue a press
release announcing such Fundamental Change referred to in the Fundamental Change Notice, the form and content of which press release shall be determined by the Company in its sole discretion. The
failure to issue any such press release or any defect therein shall not affect the validity of the Fundamental Change Notice or any proceedings for the redemption of any Note which any Securityholder
may elect to have the Company redeem as provided in this Section 3.14. 

        Each
Fundamental Change Notice shall specify the circumstances constituting the Fundamental Change, the redemption right at the option of the Holders arising as a result of the
Fundamental Change, the Fundamental Change Redemption Date, the Fundamental Change Redemption Price, that the Holder must exercise the redemption right on or prior to the close of business on the
Fundamental Change Redemption Date (the "Fundamental Change Expiration Time"), that the Holder shall have the right to withdraw any Securities
surrendered prior to the Fundamental Change Expiration Time, a description of the procedure which a Securityholder must follow to exercise such redemption right and to withdraw any surrendered
Securities, the place or places where the Holder is to surrender such Holder's Securities, the amount of interest 

33

 

accrued
on each Security to (but excluding) the Fundamental Change Redemption Date and the CUSIP number or numbers of the Securities (if then generally in use). 

        No
failure of the Company to give the foregoing notices and no defect therein shall limit the Securityholders' redemption rights or affect the validity of the proceedings for the
redemption of the Securities pursuant to this Section 3.14. 

        (c)   For
a Security, other than a Global Security, to be so redeemed at the option of the Holder, 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 Security with a written notice elect repayment upon a Fundamental Change stating: 

        (1)   the
certificate number of the Security which the Holder will deliver to be purchased; 

        (2)   the
portion of the Original Principal Amount of the Security which the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof;
and 

        (3)   that
such Security shall be purchased pursuant to the terms and conditions specified in paragraph 7 of the Securities. 

together
with such Securities duly endorsed for transfer, on or before the Fundamental Change Expiration Time. All questions as to the validity, eligibility (including time of receipt) and acceptance
of any Security for redemption shall be determined by the Company, whose determination shall be final and binding absent manifest error. 

        (d)   Prior
to 10:00 am (New York City Time) on the Business Day following the Fundamental Change Redemption Date, the Company will deposit with the Paying Agent (or, if the
Company or a Subsidiary or an Affiliate of either of them is acting as Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money sufficient to redeem on
the Fundamental Change Redemption Date all the Securities to be redeemed on such date at the Fundamental Change Redemption Price; provided that if such payment is made on the Fundamental Change
Redemption Date it must be received by the Paying Agent by 10:00 a.m. New York City time, on such date. Payment for Securities surrendered for redemption (and not withdrawn) prior to the
Fundamental Change Expiration Time will be made promptly (but in no event more than five (5) Business Days) following the Fundamental Change Redemption Date by mailing checks for the amount
payable to the Holders of such Securities entitled thereto as they shall appear in the Security register. 

        (e)   In
the case of a reclassification, change, consolidation, merger, combination, sale or conveyance to which Section 11.14 applies, in which the Common Stock of the
Company is changed or exchanged as a result into the right to receive stock, securities or other property or assets (including cash), 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 such change or exchange becomes effective in excess of 50% of the aggregate fair
market 

34

  

value of such stock, securities or other property or assets (including cash) (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 Securities to cause the Company to repurchase the Securities following a Fundamental Change, including without limitation the applicable provisions of this Section 3.14
and the definitions of Common Stock and 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 and the common stock issued by such Person (in lieu of the Company and the Common Stock of the Company). 

        (f)    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 redemption rights of the Holders of Securities in the event of a Fundamental Change.

Certificates). 

        SECTION
4.03    Compliance Certificate.    The Company shall deliver to the Trustee within 120 days after the

presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 14.02. 

        The
Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time
to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York, for such purposes. 

        SECTION
4.06    Delivery of Certain Information.    At any time when the Company is not subject to Section 13

of the covenants and conditions of this Indenture to be performed by the Company or the Guarantor, as the case may be, such successor Person shall succeed to and be substituted for the Company or the
Guarantor, as the case may be, with the same effect as if it had been named herein as the party of this first part. Such successor Person thereupon may cause to be signed, and may issue either in its
own name or in the name of Northwest Airlines Corporation or Northwest Airlines, Inc., as the case may be, any or all of the Securities, issuable hereunder that theretofore shall not have been
signed by the Company or the Guarantor, as the case may be, and delivered to the Trustee; and, upon the order of such successor Person instead of the Company or the Guarantor, as the case may be, 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 Securities that
previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Securities that such successor Person thereafter shall cause to be signed and
delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter
issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale,
conveyance or lease, the Person named as the "Company" or the "Guarantor", as the case may be, in the first paragraph of this Indenture or any successor that shall thereafter have become such in the
manner prescribed in this Article 5 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
Securities and from its obligations under this Indenture. 

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

        SECTION
5.03    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 or lease and any such assumption comply with the provisions of this Article 5.

ARTICLE 6
  
    DEFAULTS AND REMEDIES    
    

        SECTION
6.01    Events of Default.    An "Event of Default" occurs if: 

        (1)   the
Company defaults in payment of any interest when due under the Securities and such default continues for 30 days; 

        (2)   the
Company defaults in the payment of the Original Principal Amount, the Accreted Principal Amount (or, if the Securities have been converted to semiannual coupon notes
following a Tax Event pursuant to Section 10.01 of the Indenture, the Restated Principal Amount), Redemption Price, Repurchase Price or Fundamental Change Redemption Price on any Security when
the same becomes due and payable; 

        (3)   the
Company or the Guarantor fails to comply with any of its agreements in the Securities or this Indenture (other than those referred to in clauses (1) and
(2) above) and such failure continues for 60 days after receipt by the Company of a Notice of Default; 

        (4)   the
Guarantee ceases to be in full force and effect or is declared null and void or the Guarantor denies that it has any further liability under the Guarantee, or gives
notice to such effect (other than by reason of the termination of this Indenture or the release of the Guarantee in accordance with the applicable supplemental indenture) and such condition continues
for 30 days after receipt by the Company of a Notice of Default; 

        (5)   the
Company or any of its Subsidiaries (including with limitation the Guarantor) pursuant to or under or within the meaning of any Bankruptcy Law: 

        (A)  commences
a voluntary case or proceeding; 

        (B)  consents
to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it; 

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

        (D)  makes

        (E)  files
a petition in bankruptcy or answer or consent seeking reorganization or relief; or 

        (F)  consents
to the filing of such petition or the appointment of or taking possession by a Custodian; or 

39

 

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

        (A)  is
for relief against the Company or any of its Subsidiaries (including with limitation the Guarantor) in an involuntary case or proceeding, or adjudicates the Company
or any of its subsidiaries insolvent or bankrupt; 

        (B)  appoints
a Custodian of the Company or any of its Subsidiaries (including with limitation the Guarantor) or for all or substantially all of their respective property; or 

        (C)  orders
the winding up or liquidation of the Company or any of its Subsidiaries (including with limitation the Guarantor); 

and
the order or decree remains unstayed and in effect for 90 days. 

        "Bankruptcy Law" means Title 11, United States Code, or any similar Federal or state law for the relief of debtors. 

        "Custodian" means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 

        A
Default under clause (3) or clause (4) above is not an Event of Default until the Trustee notifies the Company and the Guarantor, or the Holders of at least 25% in
aggregate Original Principal Amount of the Securities at the time outstanding notify the Company, the Guarantor and the Trustee, of the Default and the Company or the Guarantor does not cure such
Default (and such Default is not waived) within the time specified in clause (3) or clause (4) above after actual receipt of such notice. Any such notice must specify the Default, demand
that it be remedied and state that such notice is a "Notice of Default". 

        The
Company or the Guarantor shall deliver to the Trustee, within 30 days after it becomes aware of the occurrence thereof, written notice of any event which with the giving of
notice or the lapse of time, or both, would become an Event of Default under clause (3) or clause (4) above, its status and what action the Company or the Guarantor is taking or proposes
to take with respect thereto. 

        SECTION
6.02    Acceleration.    If an Event of Default (other than an Event of Default specified in
Section 6.01(5) or (6) in respect of the Company or the Guarantor) occurs and is continuing, the Trustee by written notice to the Company and the Guarantor, or the Holders of at least
25% in aggregate Original Principal Amount of the Securities at the time outstanding by notice to the Company, the Guarantor and the Trustee, may declare the Accreted Principal Amount through the date
of such declaration, and any accrued and unpaid cash interest (or if the Securities have been converted to semiannual coupon notes following a Tax Event, the Restated Principal Amount, plus accrued
interest) through the date of declaration on all the Securities to be immediately due and payable. Upon such a declaration, such Accreted Principal Amount, and such accrued and unpaid interest, if
any, shall be due and payable immediately. If an Event of Default specified in Section 6.01(5) or (6) occurs in respect of the Company or the 

40

 

Guarantor
and is continuing, the Accreted Principal Amount, and any accrued and unpaid interest (or, if the Securities have been converted to semiannual coupon notes following a Tax Event, the
Restated Principal Amount, plus accrued interest) on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any
Securityholders. The Holders of a majority in aggregate Original Principal Amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder)
may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of
the Accreted Principal Amount and any accrued and unpaid interest (or, if the Securities have been converted to semiannual coupon notes following a Tax Event, the Restated Principal Amount, plus
accrued interest) that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 7.07 have been paid. No such rescission shall affect any subsequent
Default or impair any right consequent thereto. 

        SECTION
6.03    Other Remedies.    If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of the Accreted Principal Amount on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 

        The
Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the
Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of
Default. Except as set forth in Section 2.07 hereof, no remedy is exclusive of any other remedy. All available remedies are cumulative. 

        SECTION
6.04    Waiver of Past Defaults.    Subject to Section 6.02, the Holders of a majority in aggregate
Original Principal Amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder), may waive an existing Default and its consequences
except (1) an Event of Default described in Section 6.01(1) or (2), (2) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of
each Securityholder affected or (3) a Default which constitutes a failure to convert any Security in accordance with the terms of Article 11. When a Default is waived, it is deemed
cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 6.04 shall be in lieu of Section 316(a)1(B) of the TIA and such
Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

        SECTION
6.05    Control by Majority.    The Holders of a majority in aggregate Original Principal Amount of the
Securities at the time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the
Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other
Securityholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it. This Section 6.05 shall be in lieu of Section 316(a)1(A) of
the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

41

  

        SECTION 6.06    Limitation on Suits.    A Securityholder may not pursue any remedy with respect to this Indenture
or
the Securities unless: 

        (1)   the
Holder gives to the Trustee written notice stating that an Event of Default is continuing; 

        (2)   the
Holders of at least 25% in aggregate Original Principal Amount of the Securities at the time outstanding make a written request to the Trustee to pursue the remedy; 

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

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

        (5)   the
Holders of a majority in aggregate Original Principal Amount of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the
request during such 60-day period. 

        A
Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other Securityholder. 

        SECTION
6.07    Rights of Holders to Receive Payment.    Notwithstanding any other provision of this Indenture, the
right of any Holder to receive payment of the Original Principal Amount, the Accreted Principal Amount (or if the Securities have been converted to semiannual coupon notes following a Tax Event
pursuant to Article 10, the Restated Principal Amount, plus accrued cash interest), Redemption Price, Repurchase Price, Fundamental Change Redemption Price or cash interest in respect of the
Securities held by such Holder, on or after the respective due dates expressed in the Securities or any Redemption Date, and to convert the Securities in accordance with Article 11, or to bring
suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder. 

        SECTION
6.08    Collection Suit by Trustee.    If an Event of Default described in Section 6.01(1) or
(2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or the Guarantor for the whole amount owing with respect to
the Securities and the amounts provided for in Section 7.07. 

        SECTION
6.09    Trustee May File Proofs of Claim.    In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company, the Guarantor or any other obligor upon the Securities or the
property of the Company, the Guarantor or of such other obligor or their creditors, the Trustee (irrespective of whether the Original Principal Amount, the Accreted Principal Amount, Restated
Principal Amount, Redemption Price, Repurchase Price, Fundamental Change Redemption Price or cash interest in respect of the Securities 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 on the Company or the Guarantor for the payment of 

42

 

any
such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise, 

        (a)   to
file and prove a claim for the whole amount of the Original Principal Amount, the Accreted Principal Amount, Restated Principal Amount, Redemption Price, Repurchase
Price, Fundamental Change Redemption Price or cash interest in respect of the Securities (or, if the Securities have been converted to semiannual coupon notes following a Tax Event, the Restated
Principal Amount, plus accrued interest), as the case may be, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel or any other amounts due the Trustee under Section 7.07) and of the Holders
allowed in such judicial proceeding, and 

        (b)   to
collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 

and
any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. 

        Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

        SECTION
6.10    Priorities.    If the Trustee collects any money pursuant to this Article 6, it shall pay out
the money in the following order: 

FIRST:
to the Trustee for amounts due under Section 7.07; 

SECOND:
to Securityholders for amounts due and unpaid on the Securities for the Original Principal Amount, the Accreted Principal Amount, Restated Principal Amount, Redemption Price, Repurchase Price,
Fundamental Change Redemption Price or cash interest (or, if the Securities have been converted to semiannual coupon notes following a Tax Event, the Restated Principal Amount, plus accrued cash
interest), as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and 

THIRD:
the balance, if any, to the Company or, to the extent the Trustee collects any amount pursuant to the Guarantee from the Guarantor, to the Guarantor. 

        The
Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee
shall mail to each Securityholder and the Company and the Guarantor a notice that states the record date, the payment date and the amount to be paid. 

43

 

        SECTION
6.11    Undertaking for Costs.    In any suit for the enforcement of any right or remedy under this Indenture
or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having
due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07 or a suit by Holders of more than 10% in aggregate Original Principal Amount of the Securities at the time outstanding. This Section 6.11 shall be in lieu of
Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. 

        SECTION
6.12    Waiver of Stay, Extension or Usury Laws.    Each of the Company and the Guarantor covenants (to the
extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or
other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company or the Guarantor from paying all or any portion of the Original Principal Amount, the
Accreted Principal Amount, Restated Principal Amount, Redemption Price, Repurchase Price, Fundamental Change Redemption Price or cash interest (or, if the Securities have been converted to semiannual
coupon notes following a Tax Event, the Restated Principal Amount, plus accrued interest), as contemplated herein, or which may affect the covenants or the performance of this Indenture; and each of
the Company and the Guarantor (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

        SECTION
7.01    Duties of Trustee.    

        (a)   If
an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care
and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. 

        (b)   Except

the
requirements of this Indenture, but in case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine
the certificates and opinions to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or other
facts stated therein.

held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee (acting in any capacity hereunder)

        SECTION
7.02    Rights of Trustee.    Subject to its duties and responsibilities under the provisions of

and this Indenture; 

46

 

        (j)    the
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall

so authorized in any such certificate previously delivered and not superseded. 

        SECTION
7.03    Individual Rights of Trustee.    The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates
with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11. 

        SECTION
7.04    Trustee's Disclaimer.    The Trustee makes no representation as to the validity or adequacy of this
Indenture or the Securities, it shall not be accountable for the Company's use or application of the proceeds from the Securities, it shall not be responsible for any statement in the registration
statement for the Securities under the Securities Act or in the Indenture or the Securities (other than its certificate of authentication), or the determination as to which beneficial owners are
entitled to receive any notices hereunder. 

        SECTION
7.05    Notice of Defaults.    If a Default occurs and if it is known to a Responsible Officer of the Trustee,
the Trustee shall give to each Securityholder notice of the Default within 90 days after such Responsible Officer obtains knowledge of such Default unless such Default shall have been cured or
waived before the giving of such notice. Except in the case of a Default described in Section 6.01(1) or (2), the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in the interests of Securityholders. The second sentence of this Section 7.05 shall be in lieu of the proviso to
Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA. The Trustee shall not be deemed to have knowledge of a Default unless a
Responsible Officer of the Trustee has received written notice of such Default. 

        SECTION
7.05    Reports by Trustee to Holders.    Within 60 days after each April 15 beginning with the
April 15 following the date of this Indenture, the Trustee shall mail to each Securityholder a brief report dated as of such April 15 that complies with TIA Section 313(a), if
required by such Section 313(a). The Trustee also shall comply with TIA Section 313(b)(2). 

        A
copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each securities exchange, if any, on which the Securities are listed. The Company
agrees to promptly notify the Trustee whenever the Securities become listed on any securities exchange and of any delisting thereof. 

47

  

        SECTION 7.07    Compensation and Indemnity.    The Company and the Guarantor agrees: 

        (a)   to
pay to the Trustee from time to time such reasonable compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by
it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust); 

        (b)   to
reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of
this Indenture (including the reasonable compensation and the expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable
to its negligence or bad faith; and 

        (c)   to
indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, damage, claim, liability, cost or expense
(including reasonable attorney's fees and expenses and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the
Company or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. 

        To
secure the Company's and the Guarantor's payment obligations in this Section 7.07, the Holders shall have been deemed to have granted to the Trustee a lien prior to the
Securities on all money or property held or collected by the Trustee, except that held in trust to pay the Accreted Principal Amount, Redemption Price, Repurchase Price, Fundamental Change Redemption
Price, or cash interest, if any, as the case may be, on particular Securities. 

        The
Company's and the Guarantor's payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture and the resignation or removal of the Trustee.
When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(5) or (6), the expenses including the reasonable charges and expenses of its counsel, are intended
to constitute expenses of administration under any Bankruptcy Law. 

        SECTION
7.08    Replacement of Trustee.    The Trustee may resign by so notifying the Company; provided, however, no
such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a majority in aggregate Original Principal Amount of the
Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if: 

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

        (2)   the
Trustee is adjudged bankrupt or insolvent; 

48

 

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

        (4)   the
Trustee otherwise becomes incapable of acting. 

        If
the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint, by resolution of its Board of Directors, a
successor Trustee. 

        A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the
Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee,
subject to the lien provided for in Section 7.07. 

        If
a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in
aggregate Original Principal Amount of the Securities at the time outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee. 

        If
the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee. 

        SECTION
7.09    Successor Trustee by Merger.    If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all its corporate trust business or assets to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor
Trustee. 

        SECTION
7.10    Eligibility; Disqualification.    The Trustee shall at all times satisfy the requirements of TIA
Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of
condition. Nothing herein contained shall prevent the Trustee from filing with the Commission the application referred to in the penultimate paragraph of TIA Section 310(b). 

        SECTION
7.11    Preferential Collection of Claims Against Company.    The Trustee shall comply with TIA
Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein. 

 
 

ARTICLE 8
  
    DISCHARGE OF INDENTURE    
    

49

 

        SECTION
8.01    Discharge of Liability on Securities.    When (i) the Company delivers to the Trustee all
outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company or the
Guarantor irrevocably deposits with the Trustee, the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates) or the Conversion Agent cash or, if expressly permitted by the terms
of the Securities or the Indenture, Common Stock sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in
either case the Company or the Guarantor pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee
shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers' Certificate and
Opinion of Counsel and at the cost and expense of the Company. 

        SECTION
8.02    Repayment to the Company or the Guarantor.    The Trustee and the Paying Agent shall return to the
Company or, to the extent the Trustee collects any amount pursuant to the Guarantee from the Guarantor, to the Guarantor, upon written request any money or securities held by them for the payment of
any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company or the Guarantor, as the case may be, Holders
entitled to the money or securities must look to the Company or the Guarantor for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and
the Paying Agent shall have no further liability to the Securityholders with respect to such money or securities for that period commencing after the return thereof. 

 
 

ARTICLE 9
  
    AMENDMENTS    
    

        SECTION
9.01    Without Consent of Holders.    The Company and the Trustee may amend this Indenture or the Securities
without the consent of any Securityholder: 

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

        (2)   to
comply with Article 5 or Section 11.14; 

        (3)   in
exchange for Securityholders agreeing to waive their right to require the Company to purchase all or a portion of their Securities on a specified Repurchase Date, to
add additional Repurchase Dates on which Securityholders may require the Company to purchase all or a portion of their Securities at the applicable Repurchase Price and, in addition, to pay such
Securityholders additional cash payments in connection therewith; 

        (4)   to
secure the Company's or the Guarantor's obligations under the Securities and this Indenture; 

50

 

        (5)   to
add to the Company's or the Guarantor's covenants for the benefit of the Securityholders or to surrender any right or power conferred upon the Company or the
Guarantor; 

        (6)   to
make any change to comply with the TIA, or any amendment thereto, or to comply with any requirement of the SEC in connection with the qualification of the Indenture
under the TIA, or as necessary in connection with the registration of the Securities under the Securities Act; or 

        (7)   to
make any change that does not adversely affect the rights of any Holders (it being understood that any amendment described in clause (1) above made solely to
conform this Indenture to the final offering memorandum provided to investors in connection with the initial offering of the Securities will be deemed not to adversely affect the rights or interests
of Holders). 

        SECTION
9.02    With Consent of Holders.    With the written consent of the Holders of at least a majority in
aggregate Original Principal Amount of the Securities at the time outstanding, the Company, the Guarantor and the Trustee may amend this Indenture or the Securities. However, without the consent of
each Securityholder affected, an amendment to this Indenture or the Securities may not: 

        (1)   reduce
the percentage in Original Principal Amount of Securities whose Holders must consent to an amendment; 

        (2)   make
any change in the manner or rate of accretion of Accreted Principal Amount or cash interest, reduce the rate of cash interest referred to in paragraph 1 of
the Securities, or extend the time for payment of Accreted Principal Amount or cash interest on any Security; 

        (3)   reduce
the Original Principal Amount, Accreted Principal Amount or Restated Principal Amount or cash interest, with respect to any Security, or extend the Stated

        (4)   reduce
the Redemption Price, Repurchase Price or Fundamental Change Redemption Price of any Security; 

        (5)   make
any Security payable in money or securities other than that stated in the Security; 

        (6)   make
any change in Article 10 of the Indenture, or this Section 9.02, except to increase any percentage set forth therein; 

        (7)   make
any change that adversely affects the right to convert any Security; 

        (8)   make
any change that adversely affects the right to require the Company to purchase the Securities in accordance with the terms thereof and this Indenture; 

51

 

        (9)   impair
the right to institute suit for the enforcement of any payment with respect to, or conversion of, the Securities; or 

        (10) release
the Guarantor from any of its obligations under the Guarantee other than in accordance with the terms of this Indenture. 

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

        After
an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. 

        SECTION
9.03    Compliance with Trust Indenture Act.    Every supplemental indenture executed pursuant to this Article
shall comply with the TIA. 

        SECTION
9.04    Revocation and Effect of Consents, Waivers and Actions.    Until an amendment, consent, waiver or
other action by Holders becomes effective, a consent thereto by a Holder of a Security hereunder is a continuing consent by the Holder and every subsequent Holder of that Security or portion of the
Security that evidences the same obligation as the consenting Holder's Security, even if notation of the amendment, consent, waiver or other action is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent as to such Holder's Security or portion of the Security if the Trustee receives the notice of revocation before the date as of which the amendment,
consent, waiver or action is made effective. After an amendment, consent, waiver or action becomes effective, it shall bind every Securityholder. 

        SECTION
9.05    Notation on or Exchange of Securities.    Securities authenticated and delivered after the execution
of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Board of Directors, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for outstanding Securities. 

        SECTION
9.06    Trustee to Sign Supplemental Indentures.    The Trustee shall sign any supplemental indenture
authorized pursuant to this Article 9 if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but
need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall receive, and (subject to the provisions of Section 7.01) shall be fully protected in relying
upon, in addition to the documents required by Section 14.04, an Officers' Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. 

        SECTION
9.07    Effect of Supplemental Indentures.    Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; 

52

 

and
every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. 

 
 

ARTICLE 10
  
    SPECIAL TAX EVENT CONVERSION    
    

        SECTION
10.01    Optional Conversion to Semiannual Coupon Note upon Tax Event.    From and after the date (the
"Tax Event Date") of the occurrence of a Tax Event after May 15, 2010, the Company shall have the option to elect, in lieu of having Original
Principal Amount of the Securities accrete, to have interest accrue and be paid in cash at the rate of 6.625% per annum, on a Restated Principal Amount, per $1,000 Original Principal Amount (the
"Restated Principal Amount") equal to the accrued Accreted Principal Amount through the date the Company exercises the option provided for in this
Section 10.01
(the "Option Exercise Date"). Such interest shall be payable semiannually on May 15 and November 15 of each year to Holders of record at
the close of business on May 1 and November 1 immediately preceding such interest payment date. From and after the Option Exercise Date, interest will accrue from such date or such later
date to which interest has been paid or provided for. Within 15 days of the occurrence of a Tax Event, the Company shall deliver a written notice of such Tax Event by facsimile and first-class
mail to the Trustee and within 15 days of its exercise of such option the Company shall deliver a written notice of the Option Exercise Date by facsimile and first-class mail to the Trustee and
by first class mail to the Holders of the Securities. From and after the Option Exercise Date, (i) the Company shall be obligated to pay at Stated Maturity, in lieu of the Accreted Principal
Amount of a Security, the Restated Principal Amount thereof plus accrued and unpaid interest on such Security and (ii) "Accreted Principal Amount" or similar words, as used herein, shall mean
Restated Principal Amount plus accrued and unpaid interest with respect to any Security. Securities authenticated and delivered after the Option Exercise Date may, and shall if required by the
Trustee, bear a notation in a form approved by the Trustee as to the conversion of the Securities to semiannual coupon notes. No other changes to this Indenture shall result as a result of the events
described in this Section 10.01. 

 
 

ARTICLE 11
  
    CONVERSION    
    

        SECTION
11.01    Conversion Privilege.    A Holder of a Security may convert such Security into shares of Common Stock
at any time during the periods and subject to the conditions stated in paragraph 9 of the Securities, subject to the provisions of this Article 11. The number of shares of Common Stock
issuable upon conversion of a Security per $1,000 of Original Principal Amount thereof (the "Conversion Rate") shall be determined in accordance with
the provisions of paragraph 9 of the Securities. The initial number of shares of Common Stock issuable upon conversion of a Security per $1,000 of Original Principal Amount thereof shall equal
61.8047, subject to adjustment. 

53

 

        A
Holder may convert a portion of the Original Principal Amount of a Security if the portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to
conversion of all of a Security also apply to conversion of a portion of a Security. 

        The
Trustee (or other conversion agent appointed by the Company) shall, on behalf of the Company, determine on a daily basis whether the Securities shall be convertible as a result of
the occurrence of an event specified above and, if the Securities shall be convertible, the Trustee (or other conversion
agent appointed by the Company) shall promptly deliver to the Company and the Trustee (if the Trustee is not the conversion agent) written notice thereof. Whenever the Securities shall become
convertible pursuant to the foregoing condition, 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 under the Indenture, and the Company shall also publicly announce such information and publish it on the Company's website. Any notice so given shall be
conclusively presumed to have been duly given, whether or not the holder receives such notice. 

        SECTION
11.02    Conversion Procedure.    To convert a Security, a Holder must satisfy the requirements in
paragraph 9 of the Securities. The date on which the Holder satisfies all those requirements is the conversion date (the "Conversion Date").
Following the Conversion Date, the Company shall deliver to the Holder through the Conversion Agent, in accordance with Section 11.20, a certificate for the number of full shares of Common
Stock issuable upon the conversion (or, at the option of the Company, cash in lieu thereof) and cash in lieu of any fractional share determined pursuant to Section 11.03. The Company shall
determine such full number of shares and the amounts of the required cash with respect to any fractional share, and shall set forth such information in an Officers' Certificate delivered to the
Conversion Agent. The Conversion Agent shall have no duties under this paragraph unless and until it has received such certificate. 

        The
Person in whose name the certificate is registered shall be treated as a stockholder of record on and after the Conversion Date; provided,
however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons
entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the
Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock
transfer books are open; such conversion shall be at the Conversion Rate in effect on the date that such Security shall have been surrendered for conversion, as if the stock transfer books of the
Company had not been closed. Upon conversion of a Security, such Person shall no longer be a Holder of such Security. 

        Holders
may surrender a Security for conversion by means of book-entry delivery in accordance with paragraph 9 of the Security and the regulations of the applicable
book-entry facility. 

        No
payment or adjustment will be made for dividends on, or other distributions with respect to, any Common Stock except as provided in this Article 11. On conversion of a
Security, the increases in Accreted Principal Amount and accrued cash interest attributable to the 

54

 

period
from the Issue Date of the Security through the Conversion Date, with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid
in full to the Holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the Security being converted pursuant to the
provisions hereof; and the 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 the increases in Accreted Principal Amount and accrued cash interest through the Conversion Date, and the balance, if any, of such fair market value of such Common Stock (and any such
cash payment) shall be treated as issued in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof. Notwithstanding the foregoing, accrued cash interest will be
payable upon conversion of Securities made concurrently with or after acceleration of Securities following an Event of Default. 

        If
the Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon conversion shall be based on the aggregate Original Principal Amount of
the Securities converted. 

        A
Security surrendered for conversion based on (a) the Common Stock price may be surrendered for conversion until the close of business on May 15, 2023, (b) the
Security being called for redemption may be surrendered for conversion at any time prior to the close of business on the second Business Day immediately preceding the Redemption Date, even if it is
not otherwise convertible at such time, and (c) upon the occurrence of certain corporate transactions more fully described in paragraph 9 of the Security may be surrendered for
conversion at any time from and after the date which is 15 days prior to the anticipated effective date of such transaction until 15 days after the actual date of such transaction, and
if such day is not a Business Day, the next occurring Business Day following such day. 

        Upon
surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security in an authorized
denomination equal in Original Principal Amount to the unconverted portion of the Security surrendered. 

        SECTION
11.03    Fractional Shares.    The Company will not issue a fractional share of Common Stock upon conversion
of a Security. Instead, the Company will deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined, to the nearest
1/1,000th of a share, by multiplying the per share Closing Sale Price of the Common Stock, on the last trading day prior to the Conversion Date, by the fractional amount and rounding the
product to the nearest whole cent. 

        SECTION
11.04    Taxes on Conversion.    If a Holder converts a Security, the Company shall pay any documentary, stamp
or similar issue or transfer tax due on the issue of shares of Common Stock upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be
issued in a name other than the Holder's name and any income tax which is imposed on the Holder as a result of the conversion. The Conversion Agent may refuse to deliver the certificates representing
the Common Stock being issued in a name other than the Holder's name until
the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other 

55

 

than
the Holder's name. Nothing herein shall preclude the Company from any tax withholding or directing the withholding of any tax required by law or regulations. 

        SECTION
11.05    Company to Provide Stock.    The Company shall, prior to issuance of any Securities under this
Article 11, and from time to time as may be necessary, reserve out of its authorized Common Stock that is not outstanding a sufficient number of shares of Common Stock to permit the conversion
of the Securities. 

        All
shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable
and shall be free from preemptive rights and free of any lien or adverse claim created by the Company. 

        SECTION
11.06    Adjustment for Change in Capital Stock.    Except as set forth in Section 11.14, if, after the
Issue Date of the Securities, the Company: 

        (a)   pays
a dividend or makes a distribution on its Common Stock in shares of its Common Stock; 

        (b)   subdivides
its outstanding shares of Common Stock into a greater number of shares; 

        (c)   pays
a dividend or makes a distribution of its Common Stock in shares of its Capital Stock (other than Common Stock or rights, warrants or options for its Capital
Stock); 

        (d)   combines
its outstanding shares of Common Stock into a smaller number of shares; or 

        (e)   issues
by reclassification of its Common Stock any shares of its Capital Stock (other than rights, warrants or options for its Capital Stock); 

then
the conversion privilege and the Conversion Rate in effect immediately prior to such action shall be adjusted so that the Holder of a Security thereafter converted may receive the number of
shares or other units of Capital Stock of the Company which such Holder would have owned immediately following such action if such Holder had converted the Security immediately prior to such action. 

        The
adjustment shall become effective immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision,
combination or reclassification. 

        SECTION
11.07    Adjustment for Rights Issue.    Except as set forth in Sections 11.14 and 11.19, if, after the Issue
Date, the Company distributes any rights, warrants or options to all holders of its Common Stock entitling them, for a period expiring within 60 days after the record date for such
distribution, to purchase shares of Common Stock at a price per share less than the Closing Sale Price of the Common Stock as of the Time of Determination, the Conversion Rate shall be adjusted in
accordance with the formula: 

56

 

	R'	 	=	 	R (O + N)
 (O + [(N×P)/M)]

        where:

        R' =
the adjusted Conversion Rate. 

        R =
the current Conversion Rate. 

        O
= the number of shares of Common Stock outstanding on the record date for the distribution to which this Section 11.07 is being applied. 

        N =
the number of additional shares of Common Stock offered pursuant to the distribution. 

        P =
the offering price per share of the additional shares. 

        M =
the Average Sale Price, minus, in the case of (i) a distribution to which Section 11.06(b) applies or (ii) a distribution to which Section 11.08
applies, for which, in each case, (x) the record date shall occur on or before the record date for the distribution to which this Section 11.07 applies and (y) the
Ex-Dividend Time shall occur on or after the date of the Time of Determination for the distribution to which this Section 11.07 applies, the fair market value (on the record date
for the distribution to which this Section 11.07 applies) of: 

        (i)    the
Capital Stock of the Company distributed in respect of each share of Common Stock in such Section 11.06(b) distribution; and 

        (ii)   the
assets of the Company or debt securities or any rights, warrants or options to purchase securities of the Company distributed in respect of each share of Common
Stock in such Section 11.08 distribution. 

        The
Board of Directors shall determine fair market values for the purposes of this Section 11.07. 

        The
adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive the rights, warrants or options to which this
Section 11.07 applies. If all of the shares of Common Stock subject to such rights, warrants or options have not been issued when such rights, warrants or options expire, then the Conversion
Rate shall promptly be readjusted to the Conversion Rate which would then be in effect had the adjustment upon the issuance of such rights, warrants or options been made on the basis of the actual
number of shares of Common Stock issued upon the exercise of such rights, warrants or options. 

        No
adjustment shall be made under this Section 11.07 if the application of the formula stated above in this Section 11.07 would result in a value of R' that is equal to or
less than the value of R. 

57

  

        SECTION 11.08    Adjustment for Other Distributions.    (a) Subject to Section 11.08(b), if, after the
Issue Date of the Securities, the Company distributes to all holders of its Common Stock any of its assets excluding distributions of Capital Stock or equity interests referred to in
Section 11.08(b), or evidence of indebtedness or any rights, warrants or options to purchase securities of the Company (including securities or cash, but excluding (x) distributions of
Capital Stock referred to in Section 11.06 and distributions of rights, warrants or options referred to in Section 11.07 and (y) cash dividends or other cash distributions that
are paid out of consolidated current net earnings or earnings retained in the business as shown on the books of the Company unless such cash dividends or other cash distributions are Extraordinary
Cash Dividends), the Conversion Rate shall be adjusted, subject to the provisions of Section 11.08(c), in accordance with the formula: 

	 
	 	 
	 	 

	R'	 	=	 	R × M
 M - F

where:

        R' =
the adjusted Conversion Rate. 

        R =
the current Conversion Rate. 

        M =
the Average Sale Price, minus, in the case of a distribution to which Section 11.06(c) applies, for which (i) the record date shall occur on or before the record
date for the distribution to which this Section 11.08 applies and (ii) the Ex-Dividend Time shall occur on or after the date of the Time of Determination for the distribution
to which this Section 11.08 applies, the fair market value
(on the record date for the distribution to which this Section 11.08 applies) of any Capital Stock of the Company distributed in respect of each share of Common Stock in such
Section 11.06(c) distribution. 

        F =
the fair market value (on the record date for the distribution to which this Section 11.08 applies) of the assets, securities, rights, warrants or options to be
distributed in respect of each share of Common Stock in the distribution to which this Section 11.08 is being applied (including, in the case of cash dividends or other cash distributions
giving rise to an adjustment, all such cash distributed concurrently). 

        The
Board of Directors shall determine fair market values for the purposes of this Section 11.08. 

        The
adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive the distribution to which this Section 11.08
applies. 

        For
purposes of this Section 11.08, the term "Extraordinary Cash Dividend" shall mean any cash dividend or distribution with
respect to the Common Stock the amount of which, together with the aggregate amount of cash dividends on the Common Stock to be aggregated with such cash dividend in accordance with the provisions of
this paragraph, exceeds the threshold percentage set forth in item (i) below. For purposes of item (i) below, the 

58

 

"Ex-Dividend Measurement Period" with respect to a cash dividend on the Common Stock shall mean the 365 consecutive day period ending on the
date prior to the Ex-Dividend Time with respect to such cash dividend, and the "Relevant Cash Dividends" with respect to a cash dividend on
the Common Stock shall mean the cash dividends on the Common Stock with Ex-Dividend Times occurring in the Ex-Dividend Measurement Period. 

          (i)  If,
upon the date prior to the Ex-Dividend Time with respect to a cash dividend on the Common Stock, the aggregate amount of such cash dividend together
with the amounts of all Relevant Cash Dividends exceeds on a per share basis 5% of the Closing Sale Price of the Common Stock on the last trading day preceding the date of declaration by the Board of
Directors of the cash dividend or distribution with respect to which this provision is being applied, then such cash dividend together with all Relevant Cash Dividends, shall be deemed to be an
Extraordinary Cash Dividend and for purposes of applying the formula set forth above in this Section 11.08, the value of "F" shall be equal to (y) the aggregate amount of such cash
dividend together with the amount of all Relevant Cash
Dividends, minus (z) the aggregate amount of all Relevant Cash Dividends for which a prior adjustment in the Conversion Rate was previously made under this Section 11.08. 

In
making the determinations required by item (i) above, the amount of cash dividends paid on a per share basis and the amount of any Relevant Cash Dividends specified in item (i) above,
shall be appropriately adjusted to reflect the occurrence during such period of any event described in Section 11.06. 

        (b)   If,
after the Issue Date of the Securities, the Company pays a dividend or makes a distribution to all holders of its Common Stock consisting of Capital Stock of any
class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company, the Conversion Rate shall be adjusted in accordance with the formula: 

R' =
R × (1 + F/M) 

        where: 

        R' =
the adjusted Conversion Rate. 

        R =
the current Conversion Rate. 

        M =
the average of the Closing Sale Prices of the Common Stock for the ten (10) trading days commencing on and including the fifth trading day after the date on which
"ex-dividend trading" commences for such dividend or distribution on The New York Stock Exchange or such other national or regional exchange or market which such securities are then listed
or quoted (the "Ex-Dividend Date"). 

        F =
the fair market value of the securities distributed in respect of each share of Common Stock for which this Section 11.08(b) applies shall mean the number of securities
distributed in respect of each share of Common Stock multiplied by the average of the Closing 

59

 

Sale
Prices of those securities distributed for the ten (10) trading days commencing on and including the fifth trading day after the Ex-Dividend Date. 

        (c)   In
the event that, with respect to any distribution to which Section 11.08(a) would otherwise apply, the difference between "M-F" as defined in the
formula set forth in Section 11.08(a) is less than $1.00 or "F" is equal to or greater than "M", then the adjustment provided by Section 11.08(a) shall not be made and in lieu thereof
the provisions of Section 11.14 shall apply to such distribution. 

        SECTION
11.09    When Adjustment May Be Deferred.    No adjustment in the Conversion Rate need be made unless the
adjustment would require an increase or decrease of at least 1% in the Conversion Rate. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment
and all adjustments that are made and carried forward shall be taken in the aggregate in order to determine if the 1% threshold is met. 

        All
calculations under this Article 11 shall be made to the nearest cent or to the nearest 1/1,000th of a share, as the case may be. 

        SECTION
11.10    When No Adjustment Required.    No adjustment need be made for a transaction referred to in
Section 11.06, 11.07, 11.08 or 11.14 if Securityholders are to participate in the transaction on a basis and with notice that the Board of Directors determines to be fair and appropriate in
light of the basis and notice on which holders of Common Stock participate in the transaction. Such participation by Securityholders may include participation upon conversion provided that an
adjustment shall be made at such time as the Securityholders are no longer entitled to participate. 

        No
adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest. 

        No
adjustment need be made for a change in the par value or no par value of the Common Stock. 

        To
the extent the Securities become convertible pursuant to this Article 11 into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. 

        No
adjustment will be made pursuant to this Article 11 that would result, through the application of two or more provisions hereof, in the duplication of any adjustment. 

        SECTION
11.11    Notice of Adjustment.    Whenever the Conversion Rate is adjusted, the Company shall promptly mail to
Securityholders a notice of the adjustment. The Company shall file with the Trustee and the Conversion Agent such notice and a certificate from the Company's independent public accountants briefly
stating the facts requiring the adjustment and the manner of computing it. Upon receipt by it of such notice, and at the written request of the Company, the Conversion Agent will promptly mail such
notice to Securityholders at the Company's expense. The certificate shall be conclusive evidence that the adjustment is correct. Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate except to exhibit the same to any Holder desiring inspection thereof. 

60

 

        SECTION
11.12    Voluntary Increase.    The Company from time to time may increase the Conversion Rate by any amount
for any period of time. Whenever the Conversion Rate is increased, the Company shall mail to Securityholders and file with the Trustee and the Conversion Agent a notice of the increase. The Company
shall mail the notice at least 15 days before the date the increased Conversion Rate takes effect. The notice shall state the increased Conversion Rate and the period it will be in effect. 

        A
voluntary increase of the Conversion Rate does not change or adjust the Conversion Rate otherwise in effect for purposes of Section 11.06, 11.07 or 11.08 or 11.14. 

        SECTION
11.13    Notice of Certain Transactions.    If: 

        (a)   the
Company takes any action that would require an adjustment in the Conversion Rate pursuant to Section 11.06, 11.07 or 11.08 (unless no adjustment is to occur
pursuant to Section 11.10); or 

        (b)   the
Company takes any action that would require a supplemental indenture pursuant to Section 11.14; or 

        (c)   there
is a liquidation or dissolution of the Company; 

then
the Company shall mail to Securityholders and file with the Trustee and the Conversion Agent a notice stating the proposed record date for a dividend or distribution or the proposed effective
date of a subdivision, combination, reclassification, consolidation, merger, binding share exchange, transfer,
liquidation or dissolution. The Company shall file and mail the notice at least 15 days before such date. Failure to file or mail the notice or any defect in it shall not affect the validity of
the transaction. 

        SECTION
11.14    Reorganization of Company; Special Distributions.    If the Company is a party to a transaction
subject to Article 5 (other than a sale of all or substantially all of the assets of the Company in a transaction in which the holders of Common Stock immediately prior to such transaction do
not receive securities, cash, property or other assets of the Company or any other Person) or a merger or binding share exchange which reclassifies or changes its outstanding Common Stock, the Person
obligated to deliver securities, cash or other assets upon conversion of Securities shall enter into a supplemental indenture. If the issuer of securities deliverable upon conversion of Securities is
an Affiliate of the successor Company, that issuer shall join in the supplemental indenture. 

        The
supplemental indenture shall provide that the Holder of a Security may convert it into the kind and amount of securities, cash or other assets which such Holder would have received
immediately after the consolidation, merger, binding share exchange or transfer if such Holder had converted the Security immediately before the effective date of the transaction, assuming (to the
extent applicable) that such Holder (i) was not a constituent Person or an Affiliate of a constituent Person to such transaction; (ii) made no election with respect thereto; and
(iii) was treated alike with the plurality of non-electing Holders. The supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practical
to the adjustments provided for in this Article 11. The successor Company shall mail to Securityholders a notice briefly describing the supplemental indenture. 

61

 

        If
any such transaction constitutes a Fundamental Change, the Notes shall cease to be convertible after the fifteenth day following the transaction giving rise to such Fundamental
Change. 

        If
this Section applies, neither Section 11.06 nor 11.07 applies. 

        If
the Company makes a distribution to all holders of its Common Stock of any of its assets, or debt securities or any rights, warrants or options to purchase securities of the Company
that would otherwise result in an adjustment in the Conversion Rate pursuant to the provisions of Section 11.08, then, from and after the record date for determining the holders of Common Stock
entitled to receive the distribution, a Holder of a Security that converts such Security in accordance with the provisions of this Indenture shall upon such conversion be entitled to receive, in
addition to the shares of Common Stock into which the Security is convertible, the kind and amount of securities, cash or other assets comprising the distribution that such Holder would have received
if such Holder had converted the Security immediately prior to the record date for determining the holders of Common Stock entitled to receive the distribution. 

        SECTION
11.15    Company Determination Final.    Any determination that the Company or the Board of Directors must
make pursuant to Section 11.03, 11.06, 11.07, 11.08, 11.09, 11.10, 11.14 or 11.17 is conclusive. 

        SECTION
11.16    Trustee's Adjustment Disclaimer.    The Trustee has no duty to determine when an adjustment under
this Article 11 should be made, how it should be made or what it should be. The Trustee has no duty to determine whether a supplemental indenture under Section 11.14 need be entered into
or whether any provisions of any supplemental indenture are correct. The Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued
upon conversion of Securities. The Trustee shall not be responsible for the Company's failure to comply with this Article 11. Each Conversion Agent (other than the Company or an Affiliate of
the Company) shall have the same protection under this Section 11.16 as the Trustee. 

        SECTION
11.17    Simultaneous Adjustments.    In the event that this Article 11 requires adjustments to the
Conversion Rate under more than one of Sections 11.06, 11.07 or 11.08, and the record dates for the distributions giving rise to such adjustments shall occur on the same date, then such adjustments
shall be made by applying, first, the provisions of Section 11.06, second, the provisions of Section 11.08 and, third, the provisions of Section 11.07. 

        SECTION
11.18    Successive Adjustments.    After an adjustment to the Conversion Rate under this Article 11,
any subsequent event requiring an adjustment under this Article 11 shall cause an adjustment to the Conversion Rate as so adjusted. 

        SECTION
11.19    Rights Issued in Respect of Common Stock Issued Upon Conversion.    Each share of Common Stock issued
upon conversion of Securities pursuant to this Article 11 shall be entitled to receive the appropriate number of common stock or preferred stock purchase rights, as the case may be (the
"Rights"), if any, that all shares of Common Stock are entitled to receive in accordance with any rights agreement that may be in effect at the time of 

62

 

such
issuance (a "Rights Agreement") and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in
each case as may be provided by the terms of any such Rights Agreement. Provided that such Rights Agreement requires that each share of Common Stock issued by the Company (including those that might
be issued upon conversion of Securities) at any time prior to the distribution of separate certificates representing the Rights be entitled to receive such Rights, then, notwithstanding anything else
to the contrary in this Article 11, there shall not be any adjustment to the conversion privilege or Conversion Rate or any other term or provision of the Securities as a result of the issuance
of Rights, the distribution of separate certificates representing the
Rights, the exercise or redemption of such Rights in accordance with any such Rights Agreement, or the termination or invalidation of such Rights. Notwithstanding anything to the contrary herein,
nothing in this provision is intended to confer on the Common Stock issuable upon conversion of Securities any right that is different than the rights to which all shares of Common Stock of the
Company are entitled to receive. 

        SECTION
11.20    Company's Right to Elect to Pay Cash or Common Stock.    In lieu of delivery of Common Stock upon
notice of conversion of any Securities, the Company may elect to pay holders surrendering Securities an amount in cash per $1,000 Original Principal Amount per Security equal to the Average Sale Price
of Common Stock for the five consecutive trading days immediately following either (a) the date of notice of election to deliver cash as described below if the Company has not given notice of
redemption, or (b) the conversion date, in the case of conversion following the notice of redemption specifying that the Company intends to deliver cash upon conversion, in either case
multiplied by the Conversion Rate in effect on that date. The Company will inform the holders through the Trustee no later than two business days following the conversion date of its election to
deliver shares of Common Stock or to pay cash in lieu of delivery of Common Stock, unless the Company has already informed holders of its election in connection with its optional redemption of the
Securities pursuant to Section 3.01 herein. If the Company elects to deliver all of such payment in Common Stock, the Common Stock will be delivered through the Conversion Agent no later than
the fifth business day following the Conversion Date. If the Company elects to pay all or a portion of such payment in cash, the payment, including any delivery of Common Stock, will be made to
holders surrendering Securities no later than the tenth business day following the applicable conversion date. If an Event of Default (other than a default in a cash payment upon conversion of the
Securities) has occurred and is continuing, the Company may not pay cash upon conversion of any Security or portion of a Security (other than cash for fractional shares). 

 
 

ARTICLE 12
  
    PAYMENT OF INTEREST    
    

        SECTION
12.01    Interest Payments.    Interest on any Security that is payable, and is punctually paid or duly
provided for, on any applicable payment date shall be paid to the person in whose name that Security is registered at the close of business on the Regular Record Date or accrual date, as the case may
be, for such interest at the office or agency of the Company maintained for such purpose. Each installment of semiannual interest on any Security shall be paid in same-day funds by
transfer to an account maintained by the payee located inside the United States, if the Trustee shall have received proper wire transfer instructions from such 

63

 

payee
not later than the related Regular Record Date or accrual date, as the case may be, or, if no such instructions have been received, by check drawn on a bank in New York City mailed to the payee
at its address set forth on the Registrar's books. In the case of a permanent Global Security, semiannual interest payable on any applicable payment date will be paid to the Depositary, with respect
to that portion of such permanent Global Security held for its account by Cede & Co. for the purpose of permitting such party to credit the interest received by it in respect of such permanent
Global Security to the accounts of the beneficial owners thereof. 

        SECTION
12.02    Defaulted Interest.    Except as otherwise specified with respect to the Securities, any interest on
any Security that is payable, but is not punctually paid or duly provided for, within 30 days following any applicable payment date (herein called "Defaulted Interest", which term shall include
any accrued and unpaid interest that has accrued on such defaulted amount in accordance with paragraph 1 of the Securities), shall forthwith cease to be payable to the registered Holder thereof
on the relevant Regular Record Date or accrual date, as the case may be, by virtue of having been such Holder, and such Defaulted Interest may 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 Securities are registered at the close of business on a special record
date for the payment of such Defaulted Interest, which shall be 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 Security and the date of the proposed payment (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed 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 (the "Special Record Date") for the payment of such Defaulted Interest which shall be not more than
15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities at his address as it appears on the list of Securityholders maintained pursuant to
Section 2.05 not less than 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 mailed as
aforesaid, such Defaulted Interest shall be paid to the persons in whose names the Securities are registered at the close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (2). 

        (2)   The
Company may make payment of any Defaulted Interest on the Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on
which such Securities may be listed, and upon such 

64

 

notice
as may be required by such exchange, 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
12.03    Interest Rights Preserved.    Subject to the foregoing provisions of this Article 12 and
Section 2.06, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to quarterly interest
accrued and unpaid, and to accrue, which were carried by such other Security. 

 
 

ARTICLE 13
  
    GUARANTEE    
    

        SECTION
13.01    Unconditional Guarantee.    The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee the due and punctual payment of the Accreted Principal Amount of and cash interest with respect to, such Security, when and as the same shall become
due and payable, whether at maturity, by acceleration or redemption or otherwise, in accordance with the terms of such Security and of this Indenture. In case of the failure of the Company punctually
to pay any such Accreted Principal Amount of and cash interest payment, the Guarantor hereby agrees to cause any such payment to be made punctually when and as the same shall become due and payable,
whether at maturity, upon acceleration or redemption or otherwise, and as if such payment were made by the Company. 

        The
Guarantor hereby agrees that its obligations hereunder shall be as principal and not merely as surety, and shall be absolute and unconditional, irrespective of, and shall be
unaffected by, any invalidity, irregularity or failure to enforce the provisions of any such Security or this Indenture, or any waiver, modification, consent or indulgence granted to the Company with
respect thereto (unless the same shall also be provided the Guarantor), by the Holder of such Security or the Trustee, the recovery of any judgment against the Company or any action to enforce the
same, or any other circumstances which may otherwise constitute a legal or equitable discharge of a surety or guarantor. The Guarantor hereby waives diligence, presentment, demand of payment, filing
of claims with a court in the event of merger, insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to any such Security
or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged except by
payment in full of the Accreted Principal Amount of and cash interest in respect of, the Securities and the complete performance of all other obligations contained in the Securities. 

        The
Guarantor hereby irrevocably agrees that any claim or other rights that it may now or hereafter acquire against the Company that arise from the existence, payment, performance or
enforcement of the Company's obligations under the Securities or this Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, any
right to participate in any claim or remedy of the Holder of any Securities against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law,
including, without limitation, the right to take or receive from 

65

 

the
Company, directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such claim or other rights, shall be subordinated and postponed in
right of payment to the prior payment and performance in full of all of the Company's obligations under the Securities or this Indenture. If any amount shall be paid to the Guarantor in violation of
the preceding sentence and the obligations of the Company guaranteed by the Guarantor pursuant hereto shall not have been paid in full, such amount shall be deemed to have been paid to the Guarantor
for the benefit of, and held in trust for the benefit of, the Holders of Securities entitled to the benefit of this Guarantee, and shall forthwith be paid to the Trustee. 

        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, 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 significant 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 Securities are, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on the Securities, 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, for the purposes of the amounts due under the Guarantee, the Securities 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. The form of Guarantee is attached hereto as Exhibit A-2. 

        SECTION
13.02    Severability.    In case any provision of any Guarantee shall be invalid, illegal or unenforceable,
the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

        SECTION
13.03    Priority of Guarantees.    The Guarantee issued by the Guarantor shall be senior unsecured
obligations of the Guarantor, ranking pari passu with all other existing and future senior unsecured indebtedness of the Guarantor, if any. 

        SECTION
13.04    Limitation of Guarantor's Liability.    The Guarantor and by its acceptance hereof each Holder
confirms that it is the intention of all such parties that the guarantee by the Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy
Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To
effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the obligations of the Guarantor under its Guarantee shall be limited to the maximum amount that will
not, after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the obligations of the Guarantor under its Guarantee constituting such fraudulent transfer or
conveyance. 

        SECTION
13.05    Subrogation.    The Guarantor shall be subrogated to all rights of Holders against the Company in
respect of any amounts paid by the Guarantor pursuant to the provisions of Section 13.01; provided, however, that, if an Event of Default has
occurred and is continuing, the Guarantor shall not be entitled to enforce or receive any payments arising out of, 

66

 

or
based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Securities shall have been paid in full. 

        SECTION
13.06    Reinstatement.    The Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree)
that the Guarantee provided for in Section 13.01 shall continue to be effective or be reinstated, as the case may be, (a) if at any time, payment, or any part thereof, of any obligations
or interest thereon is rescinded or must otherwise be restored by a Holder to the Company upon the bankruptcy or insolvency of the Company or the Guarantor and (b) at any time the Guarantor
(and each Person who becomes a Guarantor) guarantees any indebtedness or obligations of the Company. 

        SECTION
13.07    Release of the Guarantor.    Concurrently with the discharge of the Securities under
Section 8.01, the Guarantor shall be released from all its obligations under its Guarantee under this Article 13. 

        So
long as no Default exists or with notice or lapse of time or both, would exist, the Guarantee issued by the Guarantor shall be automatically and unconditionally released and
discharged upon (a) any sale,
exchange, transfer to any Person that is not an Affiliate of the Company of all of the Capital Stock of the Guarantor owned by the Company, which transaction is otherwise in compliance with the
Indenture or (b) any release or discharge of all guarantees by the Guarantor of any indebtedness or obligations of the Company other than the Guarantees of the Securities. 

        SECTION
13.08    Benefits Acknowledged.    The Guarantor acknowledges that it will receive direct and indirect
benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

[FORM OF REVERSE SIDE OF NOTE]
  6.625% Senior Convertible Note due 2023    
    

	1.
	Interest.

        The
Company promises to pay interest in cash on the Original Principal Amount of this Note at the rate of 6.625% per year from the Issue Date, or from the most recent date to which
interest has been paid or provided for, until May 15, 2010. During such period, the Company will pay cash interest semiannually in arrears on each Interest Payment Date to Holders of record at
the close of business on each Regular Record Date immediately preceding such Interest Payment Date. Each payment of cash interest on the Securities will include interest accrued through the day
immediately preceding the most recent Interest Payment Date (or the Repurchase Date, Redemption Date, the Fundamental Change Redemption Date or, in certain circumstances, the Conversion Date, as the
case may be). Any payment required to be made on any day that is not a Business Day will be made on the next succeeding Business Day. The interest rate will be calculated using a 360-day
year composed of twelve 30-day months. 

        Beginning
May 15, 2010, this Security shall not bear interest, except as specified in this paragraph or in paragraph 11 hereof. From such date, the Original Principal
Amount shall commence increasing daily by the rate of 6.625% to produce the Accreted Principal Amount. The Accreted Principal Amount will compound seminannually, not daily. At Stated Maturity, the
Holder of this Security will receive $2,333.32 for each $1,000 Original Principal Amount of Securities, which is the fully Accreted Principal Amount of this Security on such date, unless the Security
has been earlier redeemed or converted, which for each $1,000 Original Principal Amount will be equal to such Original Principal Amount of $1,000 per Security increased daily by 6.625% per year as
provided in the Indenture. The yield will be calculated using a 360-day year composed of twelve 30-day months. If the Accreted Principal Amount hereof or any portion of such
Accreted Principal Amount is not paid when due (whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to
paragraph 6 hereof, upon the date set for payment of the Repurchase Price or Fundamental Change Redemption Price pursuant to paragraph 7 hereof or upon the Stated Maturity of this
Security) or if installments of cash interest due hereon are not paid when due in accordance with this paragraph, then in each such case the overdue amount shall, to the extent permitted by law, bear
interest at 6.625% per year, as the case may be, in effect following the date such overdue amount was due, compounded seminannually, which interest shall accrue from the date such
overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. The accrual of such
interest on overdue amounts shall be in lieu of, and not in addition to, any subsequent increase in the Accreted Principal Amount. 

        Interest
on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security is registered
at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. Each installment of interest on any Security shall be paid in
same-day funds by transfer to an account maintained by the payee located inside the United States. 

A-1-5

 
	2.
	Method
of Payment. 

        Subject
to the terms and conditions of the Indenture, the Company will make payments in respect of Accreted Principal Amount, Redemption Prices, Repurchase Prices, Fundamental Change
Redemption Prices and at Stated Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. In addition, the Company will pay cash interest
from the Issue Date until May 15, 2010, as more fully described in paragraph 1 hereof. The Company will pay any cash amounts in money of the United States that at the time of payment is
legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money. 

	3.
	Paying
Agent, Conversion Agent and Registrar. 

        Initially,
U.S. Bank National Association (the "Trustee") will act as Paying Agent, Conversion Agent and Registrar. The Company may
appoint and change any Paying Agent, Conversion Agent and Registrar or co-registrar without notice, other than notice to the Trustee except that the Company will maintain at least one
Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their
Affiliates may act as Paying Agent, Conversion Agent, Registrar or co-registrar. 

	4.
	Indenture.

        The
Company issued the Securities pursuant to an Indenture dated as of May 20, 2003 (the "Indenture"), among the Company, the
Guarantor and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Securities themselves and the Trust Indenture Act
of 1939, as in effect from time to time (the "TIA"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the
Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a statement of those terms. 

        The
Securities are unsecured and unsubordinated obligations of the Company limited to $172,500,000 aggregate Original Principal Amount (subject to Section 2.07 of the Indenture).
The Indenture does not limit other indebtedness of the Company, secured or unsecured.

and unpaid interest from the date of such conversion to but not including the Redemption Date; but in no event will this Security be redeemable before May 15, 2010.

2010, May 15, 2013 and May 15, 2018 at a Repurchase Price equal to 100% of the Accreted Principal Amount of such Securities on the applicable Repurchase Date plus accrued and unpaid
interest, if any, to but not including the Repurchase Date, upon delivery of a Repurchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the
date that is 20 Business Days prior to such Repurchase Date until the close of business on the third Business Day prior to such Repurchase Date and upon delivery of the Securities to the Paying Agent
by the Holder as set forth in the Indenture. 

        The
Repurchase Price may be paid, at the option of the Company, in cash or by the issuance and delivery of shares of Common Stock of the Company, or in any combination thereof in
accordance with the Indenture. 

A-1-7

 

        If
prior to a Repurchase Date this Security has been converted to a semiannual coupon note following the occurrence of a Tax Event, the Repurchase Price will be equal to the Restated
Principal Amount plus accrued and unpaid cash interest from the date of conversion to the Repurchase Date but not including the Repurchase Date as provided in the Indenture. 

        At
the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or a portion of the Securities in integral
multiples of $1,000 Original Principal Amount held by such Holder no later than 30 Business Days after the occurrence of a Fundamental Change of the Company for a Fundamental Change Redemption Price
equal to 100% of the Accreted Principal Amount of such Securities plus accrued and unpaid cash interest, if any, to but not including the Fundamental Change Redemption Date, which Fundamental Change
Redemption Price shall be paid in cash. 

        A
third party may make the offer and purchase of the Securities in lieu of the Company in accordance with the Indenture. 

        Holders
have the right to withdraw any Repurchase Notice or Fundamental Change Redemption Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in
accordance with the provisions of the Indenture. 

        If
cash (and/or securities if permitted under the Indenture) sufficient to pay the Repurchase Price or Fundamental Change Redemption Price, as the case may be, of all Securities or
portions thereof to be purchased as of the Repurchase Date or the Fundamental Change Redemption Date, as the case may be, is deposited with the Paying Agent on the Business Day following the
Repurchase Date or the Fundamental Change Redemption Date, as the case may be, the Accreted Principal Amount shall cease to increase, and cash interest, if any, shall cease to accrue on such
Securities (or portions thereof) on such Repurchase Date or Fundamental Change Redemption Date, as the case may be, and the Holder thereof shall have no other rights as such (other than the right to
receive the Repurchase Price or Fundamental Change Redemption Price, as the case may be, if any, upon surrender of such Security). 

	8.
	Notice
of Redemption. 

        Notice
of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder's
registered address. If money sufficient to pay the Redemption Price of, and accrued and unpaid cash interest, if any, with respect to, all Securities (or portions thereof) to be redeemed on the
Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on such Redemption Date, the Accreted Principal Amount shall cease to increase, and accrued cash interest, if
any, shall cease to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of Original Principal
Amount may be redeemed in part but only in integral multiples of $1,000 of Original Principal Amount. 

	9.
	Conversion.

        Conversion Based on Common Stock Price.    Subject to the provisions of this paragraph 9 and notwithstanding the fact
that any other condition to conversion described below has not been satisfied, Holders may convert the Securities into Common Stock on a Conversion Date in any 

A-1-8

 

fiscal
quarter commencing after June 30, 2003 if the Closing Sale Price of the Common Stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading
day of such preceding fiscal quarter is greater than the conversion trigger price per share. The "conversion trigger price" for any fiscal quarter shall
be 120% of the accreted conversion price per share (as defined below) of Common Stock on the last trading day of such preceding fiscal quarter. If the foregoing condition is satisfied, then the
Securities will be convertible at any time of the option of the Holder, through their maturity. 

        The
"accreted conversion price per share" of Common Stock as of any day equals the quotient of: 

	•
	the
Accreted Principal Amount on that day, divided by

	•
	the
number of shares of Common Stock issuable upon conversion of $1,000 Original Principal Amount of Securities on that day. 

        Conversion Based on Trading Price of Securities.    Subject to the provisions of this paragraph 9 and notwithstanding the
fact that any other condition to conversion described below has not been satisfied, Holders may convert the Securities into Common Stock during each of the five Business Day period after any five
consecutive trading day period in which the Trading Price per $1,000 Original Principal Amount of the Securities for each day of such five day period was less than 98% of the product of the Closing
Sale Price on the applicable date and the number of shares of Common Stock issuable upon conversion of $1,000 Original Principal Amount of the Securities. Upon conversion, the Company has the right to
deliver cash or a combination of cash and Common Stock. 

        The
"Trading Price" means, on any date, the average of the secondary market bid quotations for the Securities obtained by the Trustee for
$10,000,000 Original Principal Amount of Securities at approximately 3:30 p.m., New York City time, on such date from three independent nationally recognized securities dealers selected by the
Company; provided that if at least three such bids cannot reasonably be obtained by the Trustee, but two bids are obtained, then the average of the two bids shall be used, and if only one such bid can
reasonably be obtained by the Trustee, one bid shall be used; and provided further that if the Trustee cannot reasonably obtain at least one bid for $10,000,000 Original Principal Amount of Notes from
a nationally recognized securities dealer or in the Company's reasonable judgment, the bid quotations are not indicative of the secondary market value of the Notes, then the Trading Price per $1,000
Original Principal Amount of Notes shall be deemed to be less than 98% of the product of (a) the number of shares of Common Stock issuable upon conversion of $1,000 Original Principal Amount of
Notes and (b) the Closing Sale Price on such date. 

        The
Trustee (or other conversion agent appointed by the Company) shall have no obligation to determine the Trading Price unless the Company has requested such a determination; and the
Company shall have no obligation to make such request unless a holder provides it with reasonable evidence that the Trading Price per $1,000 Original Principal Amount of Securities would be less than
98% of the product of the Closing Sale Price of Common Stock and the number of shares of Common Stock issuable upon conversion of $1,000 Original Principal Amount of Securities. If such evidence is
provided, the Company shall 

A-1-9

 

instruct
the Trustee (or other conversion agent) to determine the Trading Price of the Securities beginning on the next trading day and on each successive trading day until the Trading Price per
$1,000 Original Principal Amount of Securities is greater than 98% of the product of the Closing Sale Price and the number of shares issuable upon conversion of $1,000 Original Principal Amount of the
Securities. 

        Conversion upon Redemption.    Subject to the provisions of this paragraph 9 and notwithstanding the fact that any other
condition described herein to conversion has not been satisfied, a Holder may convert into Common Stock a Security or portion of a Security which has been called for redemption pursuant to
paragraph 6 hereof, provided such Securities are surrendered for conversion prior to the close of business on the second Business Day immediately preceding the Redemption Date. 

        Conversion Upon Certain Distributions.    Subject to the provisions of this paragraph 9 and notwithstanding the fact that
any other condition to conversion has not been satisfied, in the event that the Company declares a dividend or distribution described in Section 11.07 of the Indenture, or a dividend or a
distribution described in Section 11.08 of the Indenture where, the fair market value, per share, of such dividend or distribution per share of Common Stock, as determined in the Indenture,
exceeds 15% of the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of declaration for such dividend or distribution, the Securities may be surrendered for
conversion beginning on the date the Company gives notice to the Holders of such right, which shall not be less than 20 days prior to the Ex-Dividend Time for such dividend or
distribution, and Securities may be surrendered for conversion at any time thereafter until the close of business on the
Business Day prior to the Ex-Dividend Time or until the Company announces that such dividend or distribution will not take place. No adjustment to the Conversion Rate or the ability of the
Holders to convert this Security will be made if the Company provides, as permitted in the Indenture, for Holders to participate in the transaction without conversion or in other cases specified in
the Indenture. 

        Conversion Upon Occurrence of Certain Corporate Transactions.    Subject to the provisions of this paragraph 9 and
notwithstanding the fact that any other condition described herein to conversion has not been satisfied, in the event the Company is a party to a consolidation, merger or binding share exchange
pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 11.14 of the Indenture, the Securities may be surrendered for conversion at
any time from and after the date which is 15 days prior to the date announced by the Company as the anticipated effective time until 15 days after the actual effective date of such
transaction, and at the effective time of such transaction the right to convert a Security into Common Stock will be deemed to have changed into a right to convert it into the kind and amount of cash,
securities or other property which the holder would have received if the holder had converted its Security into Common Stock immediately prior to the transaction. If such transaction also constitutes
a Fundamental Change, a Holder will be able to require the Company to redeem all or a portion of such Holder's Notes pursuant to Paragraph 7 and Section 3.14 of the Indenture. In
addition, if such transaction constitutes a Fundamental Change, the Notes will cease to be convertible after the fifteen day following the actual effective date of the transaction giving rise to such
Fundamental Change. 

A-1-10

 

        A
Security in respect of which a Holder has delivered a Repurchase Notice or Fundamental Change Redemption Notice exercising the option of such Holder to require the Company to purchase
such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture. 

        The
initial Conversion Rate is 61.8047 shares of Common Stock per $1,000 Original Principal Amount of each Security, subject to adjustment for certain events described in the Indenture.
The Company will deliver cash or a check in lieu of any fractional share of Common Stock. The ability to surrender Securities for conversion will expire at the close of business on May 15,
2023. 

        In
the event the Company exercises its option pursuant to Section 10.01 of the Indenture to have, in lieu of having the Accreted Principal Amount increase, interest accrue on the
Security following a Tax Event, the Holder will be entitled on conversion to receive the same number of shares of Common Stock such Holder would have received if the Company had not exercised such
option.

in the Accreted Principal Amount and cash interest will not be paid on Securities that are converted; provided, however that, prior to May 15, 2010, Securities
surrendered for conversion during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date
shall be entitled to receive such interest payable on such Securities on the corresponding Interest Payment Date and (except Securities to be redeemed within this period or on the next Interest
Payment Date beginning on May 15, 2010 and thereafter) Securities surrendered for conversion during such periods must be accompanied by payment of an amount equal to the interest with respect
thereto that the registered Holder is to receive. 

        To
exercise its conversion right, a Holder must (1) complete and manually sign the conversion notice (or complete and manually sign a facsimile of such notice) and deliver such
notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the
Company or the Trustee and (4) pay any transfer or similar taxes, if required. 

        A
Holder may convert a portion of a Security if the Original Principal Amount of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment will be made for
dividends on the Common Stock except as provided in the Indenture. On conversion of a Security, increases in the Accreted Principal Amount or cash interest (or interest if the Company has exercised
its option provided for in paragraph 11 hereof) attributable to the period from the Issue Date (or, if the Company has exercised the option referred to in paragraph 11 hereof, the later
of (x) the date of such exercise and (y) the date on which interest was last paid) through the Conversion Date shall not be cancelled, extinguished or forfeited, but rather shall be
deemed to be paid in full to the Holder thereof through the delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the Security being
converted pursuant to the terms hereof; and the 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 increases in the Accreted Principal Amount or cash interest (or interest, if the Company has exercised its option provided for in paragraph 11 hereof) 

A-1-11

 

accrued
through the Conversion Date, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of
the Security being converted pursuant to the provisions hereof. 

        The
Conversion Rate will be adjusted for dividends or distributions on Common Stock payable in Common Stock or other Capital Stock of the Company; subdivisions, combinations or certain
reclassifications of Common Stock; distributions to all holders of Common Stock of certain rights to purchase Common Stock for a period expiring within 60 days of the record date for such
distribution at less than the Closing Sale Price of the Common Stock at the Time of Determination; and distributions to such holders of assets or debt securities of the Company or certain rights to
purchase securities of the Company (excluding certain cash dividends or distributions). However, no adjustment need be made if Securityholders may participate in the transaction or in certain other
cases. The Company from time to time may voluntarily increase the Conversion Rate. 

        If
the Company is a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of its assets, or upon certain distributions described in the
Indenture, the right to convert a Security into Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or another person. 

        The
Conversion Rate will not be adjusted for increases in the Accreted Principal Amount or accrued cash interest. 

	10.
	Conversion
Arrangement on Call for Redemption. 

        Any
Securities called for redemption, unless surrendered for conversion before the close of business on the Redemption Date, may be deemed to be purchased from the Holders of such
Securities at an amount not less than the Redemption Price, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to
convert them into Common Stock of the Company and to make payment for such Securities to the Trustee in trust for such Holders. 

	11.
	Tax
Event. 

        From
and after the date (the "Tax Event Date") of the occurrence of a Tax Event after May 15, 2010, the Company shall have the
option to elect, in lieu of having Accreted Principal Amount increase, to have interest accrue and be paid in cash at the rate of 6.625% per annum, on a Restated Principal Amount, per $1,000 Original
Principal Amount (the "Restated Principal Amount") equal to the accrued Accreted Principal Amount through the Tax Event Date or the date the Company
exercises the option provided for in this paragraph 11, whichever is later (the "Option Exercise Date"). Such interest shall be payable
semiannually on May 15 and November 15 of each year to Holders of record at the close of business on May 1 and November 1 immediately preceding such interest payment date.
Interest will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from the Option Exercise Date. 

A-1-12

 
	12.
	Defaulted
Interest. 

        Except
as otherwise specified with respect to the Securities, any Defaulted Interest on any Security shall forthwith cease to be payable to the registered Holder thereof on the relevant
Regular Record Date or accrual date, as the case may be, by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 12.02 of the
Indenture. 

	13.
	Denominations;
Transfer; Exchange. 

        The
Securities are in fully registered form, without coupons, in denominations of $1,000 of Original Principal Amount and integral multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required
by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities in respect of which a Repurchase Notice or Fundamental Change Redemption Notice has been given and not withdrawn (except, in the case of a Security to be
purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed. 

	14.
	Persons
Deemed Owners. 

        The
registered Holder of this Security may be treated as the owner of this Security for all purposes. 

	15.
	Unclaimed
Money or Securities. 

        The
Trustee and the Paying Agent shall return to the Company or, to the extent the Trustee collects any amount pursuant to the Guarantee from the Guarantor, to the Guarantor, upon
written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, subject to applicable unclaimed property laws.
After return to the Company or the Guarantor, as the case may be, Holders entitled to the money or securities must look
to the Company or the Guarantor for payment as general creditors unless an applicable abandoned property law designates another person. 

	16.
	Amendment;
Waiver. 

        Subject
to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in
aggregate Original Principal Amount of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Original
Principal Amount of the Securities at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend
the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 or Section 11.14 of the Indenture, to secure the Company's
obligations under this Security or to add to the Company's or the Guarantor's covenants for the benefit of 

A-1-13

 

the
Securityholders or to surrender any right or power conferred, in exchange for Holders agreeing to waive their right to require the Company to purchase all or a portion of their Securities on a
specified Repurchase Date, to add additional Repurchase Dates on which Holders may require the Company to purchase all or a portion of their Securities at the applicable Repurchase Price and, in
addition, to pay such Holders additional cash payments in connection therewith, to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA, or as
necessary in connection with the registration of the Securities under the Securities Act or to make any change that does not adversely affect the rights of any Holders. 

	17.
	Defaults
and Remedies. 

        Under
the Indenture, Events of Default include (i) the Company defaults in payment of interest when due under the Securities and such default continues for 30 days;
(ii) default in payment of the Original Principal Amount, the Accreted Principal Amount (or, if the Securities have been converted to semiannual coupon notes following a Tax Event, the Restated
Principal Amount), Redemption Price, Repurchase Price or Fundamental Change Redemption Price, as the case may be, in respect of the Securities when the same becomes due and payable;
(iii) failure by the Company or the Guarantor to comply with other agreements in the Indenture or the Securities, subject to notice and lapse of time; (iv) if the Guarantee provided
pursuant to Article 13 of the Indenture with respect to the Securities ceases to be in full force and effect or is declared null and void or the Guarantor denies that it has any further
liability under the Guarantee, or gives notice to such effect (other than by reason of the termination of this Indenture or the release of the Guarantee in accordance with the applicable supplemental
indenture) and such condition shall have continued for a period of 30 days after receipt by
the Company of a Notice of Default; and (v) certain events of bankruptcy or insolvency affecting the Company or certain of its subsidiaries. A Default under clause (iii) or
clause (iv) above is not an Event of Default until the Trustee notifies the Company and the Guarantor, or the Holders of at least 25% in aggregate Original Principal Amount of the Securities at
the time outstanding notify the Company, the Guarantor and the Trustee, of the Default and the Company or the Guarantor does not cure such Default (and such Default is not waived) within the time
specified in clause (iii) or clause (iv) above after actual receipt of such notice. 

        Securityholders
may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives
indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate Original Principal Amount of the Securities at the time outstanding may direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i)
or (ii) above) if it determines that withholding notice is in their interests. 

	18.
	Trustee
Dealings with the Company or the Guarantor. 

        Subject
to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may 

A-1-14

 

otherwise
deal with the Company or the Guarantor or their Affiliates with the same rights it would have if it were not Trustee. 

	19.
	No
Recourse Against Others. 

        A
director, officer, employee, agent, representative, stockholder or equity holder, as such, of the Company shall not have any liability for any obligations of the Company under the
Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder shall waive and release all such
liability. The waiver and release shall be part of the consideration for the issue of the Securities. 

	20.
	Authentication.

        This
Security shall not be valid until an authorized signatory of the Trustee manually signs the Trustee's Certificate of Authentication on the other side of this Security.

        SECTION
2.    Shelf Registration.    

        (a)   The
Company and the Guarantor shall prepare and file or cause to be prepared and filed with the SEC no later than a date which is ninety (90) days after the Issue
Date (the "Filing Deadline Date") a Registration Statement for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act (a "Shelf Registration
Statement") registering the resale from time to time by Holders of all of the Registrable Securities (the "Initial Shelf Registration Statement"). The Initial Shelf Registration Statement shall be on
Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by such Holders in accordance with the methods of distribution reasonably
elected by the Holders and set forth in the Initial Shelf Registration Statement; provided that in no event will such method(s) of distribution take the
form of an underwritten offering of the Registrable Securities without the prior agreement of the Company. The Company and the Guarantor shall use their reasonable best efforts to cause the Initial
Shelf Registration Statement to be declared effective under the Securities Act no later than the date (the "Effectiveness Deadline Date") that is one-hundred and eighty (180) days
after the Issue Date, and to keep, subject to Section 3(i)(A) hereof, the Initial Shelf Registration Statement (or any Subsequent Shelf Registration Statement) continuously effective under the
Securities Act until the expiration of the Effectiveness Period. Each Holder that became a Notice Holder on or prior to the date ten (10) Business Days prior to the time that the Initial Shelf
Registration Statement became effective shall be named as a selling security holder in the Initial Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to
deliver such Prospectus to purchasers of Registrable Securities in accordance with applicable law (other than laws not generally applicable to all such Holders). Notwithstanding the foregoing, no
Holder shall be entitled to have the Registrable Securities held by it covered by such Shelf Registration Statement unless such Holder has provided a Notice and Questionnaire in accordance with
Section 2(d) and is in compliance with Section 4. Neither the Company nor the Guarantor shall permit any of its security holders (other than the Holders of Registrable Securities) to
include any of the Company's or the Guarantor's securities in the Shelf Registration Statement (or any subsequent Shelf Registration Statement). 

        (b)   If
the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during the 

5

 

Effectiveness
Period, the Company and the Guarantor shall use their best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within thirty
(30) days of such cessation of effectiveness amend the Shelf Registration Statement in a manner reasonably expected by the Company and the Guarantor to obtain the withdrawal of the order
suspending the effectiveness thereof, or file an additional Shelf Registration Statement covering all of the securities that as of the date of such filing are Registrable Securities (a "Subsequent
Shelf Registration Statement"). If a Subsequent Shelf Registration Statement is filed, the Company and the Guarantor shall use reasonable efforts to cause the Subsequent Shelf Registration Statement
to become effective as promptly as is reasonably practicable after such filing or, if filed during a Deferral Period, after the expiration of such Deferral Period, and to keep such Registration
Statement (or subsequent Shelf Registration Statement), subject to Section 3(i)(A) hereof, continuously effective until the end of the Effectiveness Period. 

        (c)   The
Company and the Guarantor shall supplement and amend the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the
registration form used by the Company and the Guarantor for such Shelf Registration Statement, if required by the Securities Act or, to the extent to which the Company does not reasonably object, as
reasonably requested by the Initial Purchaser or by the Trustee on behalf of the registered Holders. 

        (d)   Each
Holder of Registrable Securities agrees that if such Holder wishes to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus,
it will do so only in accordance with this Section 2(d) and Section 3(i) and Section 4. Each Holder of Registrable Securities wishing to sell Registrable Securities
pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company at least five (5) Business Days prior to any intended distribution
of Registrable Securities under the Shelf Registration Statement. From and after the date the Initial Shelf Registration Statement is declared effective, the Company and the Guarantor shall, as
promptly as is reasonably practicable after the date a fully completed and legible Notice and Questionnaire is received by the Company, (i) if required by applicable law, file with the SEC a
post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment
to any document incorporated therein by reference or file any other document required by the SEC so that the Holder delivering such Notice and Questionnaire is named as a selling security holder in
the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Registrable Securities in accordance with
applicable law (other than laws not generally applicable to all Holders of Registrable Securities wishing to sell Registrable Securities pursuant to the Shelf Registration Statement and related
Prospectus) and, if the Company and the Guarantor shall file a post-effective amendment to the Shelf Registration Statement, use reasonable efforts to cause such
post-effective amendment to be declared effective under the Securities Act as promptly as is reasonably practicable; (ii) provide such Holder copies of any documents filed pursuant
to Section 2(d)(i); and (iii) notify such Holder as promptly as is reasonably practicable after the effectiveness under the Securities Act of any post-effective amendment
filed pursuant to Section 2(d)(i); provided that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so
inform the 

6

 

Holder
delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with
Section 3(i), provided further that if under applicable law the Company and the Guarantor have more than one option as to the type or manner of
making any such filing, they will make the required filing or filings in the manner or of a type that is reasonably expected to result in the earliest availability of the Prospectus for effecting
resales of Registrable Securities. Notwithstanding anything contained herein to the contrary, the Company and the Guarantor shall be under no obligation to name any Holder that is not a Notice Holder
as a selling security holder in any Registration Statement or related Prospectus; provided, however, that any Holder that becomes a Notice Holder
pursuant to the provisions of Section 2(d) of this Agreement (whether or not such Holder was a Notice Holder at the time the Registration Statement was initially declared effective) shall be
named as a selling security holder in the Registration Statement or related Prospectus subject to and in accordance with the requirements of this Section 2(d). 

        (e)   The
parties hereto agree that the Holders of Registrable Securities will suffer damages, and that it would not be feasible to ascertain the extent of such damages with
precision, if (i) the Initial Shelf Registration Statement has not been filed on or prior to the Filing Deadline Date, (ii) the Initial Shelf Registration Statement has not been declared
effective under the Securities Act on or prior to the Effectiveness Deadline Date, or (iii) the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in
respect of such period pursuant to Section 3(i) hereof (each of the events of a type described in any of the foregoing clauses (i) through (iii) is individually referred to
herein as an "Event," and the Filing Deadline Date in the case of clause (i), the Effectiveness Deadline Date in the case of clause (ii), and the date on which the aggregate duration of
Deferral Periods in any period exceeds the number of days permitted by Section 3(i) hereof in the case of clause (iii), being referred to herein as an "Event Date"). Events shall
be deemed to continue until the "Event Termination Date," which shall be the following dates with respect to the respective types of Events: the date the Initial Shelf Registration Statement is filed
in the case of an Event of the type described in clause (i), the date the Initial Shelf Registration Statement is declared effective under the Securities Act in the case of an Event of the type
described in clause (ii), and termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods in a period set forth in Section 3(i) to be
exceeded in the case of the commencement of an Event of the type described in clause (iii). 

        Accordingly,
commencing on (and including) any Event Date and ending on (but excluding) the next date after an Event Termination Date (an "Additional Amount Accrual Period"), the Company
and the Guarantor agree to pay an additional amount (the "Additional Amount"), payable on the Additional Amount Payment Dates to Record Holders of then outstanding Securities that are Registrable
Securities or of then outstanding shares of Underlying Common Stock issued upon conversion of Securities that are Registrable Securities, as the case may be, accruing, for each portion of such
Additional Amount Accrual Period beginning on and including an Additional Amount Payment Date (or, in respect of the first time that the Additional Amount is to be paid to Holders on a Additional
Amount Payment Date as a result of the occurrence of any particular Event, from the Event Date) and ending on but excluding the first to occur of (A) the date of the end of the Additional
Amount Accrual Period or (B) the next Additional Amount Payment Date, at a rate per annum equal 

7

 

to
one-quarter of one percent (0.25%) for the first ninety (90)-day period from the Event Date, and thereafter at a rate per annum equal to one-half of one percent
(0.50%) of the aggregate Applicable Principal Amount of such Notes, the aggregate Applicable Conversion Price of the shares of Underlying Common Stock and the Restated Principal Amount of the
Semi-annual Coupon Notes, as the case may be, in each case determined as of the Business Day immediately preceding the next Additional Amount Payment Date; provided that any Additional
Amount accrued with respect to any Security or portion thereof called for redemption on a redemption date or converted into Underlying Common Stock on a conversion date or to Semi-annual
Coupon Notes prior to the Additional Amount Payment Date shall, in any such event, be paid instead to the Holder who submitted such Security or portion thereof for redemption or conversion on the
applicable redemption date or conversion date, as the case may be, on such date (or promptly following the conversion date, in the case of conversion). Notwithstanding the foregoing, no Additional
Amounts shall accrue as to any Registrable Security from and after the earlier of (x) the date such security is no longer a Registrable Security and (y) expiration of the Effectiveness
Period. The rate of accrual of the Additional Amount with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Events.
Following the cure of all Events requiring the payment by the Company and/or the Guarantor of Additional Amounts to the Holders of Registrable Securities pursuant to this Section, the accrual of
Additional Amounts will cease (without in any way limiting the effect of any subsequent Event requiring the payment of the Additional Amount by the Company and/or the Guarantor). 

        The
Trustee, subject to the applicable provisions of the Indenture, shall be entitled on behalf of Holders of Securities, Underlying Common Stock or Semi-annual Coupon Notes,
to seek any available remedy for the enforcement of this Agreement, including for the payment of any Additional Amount. Notwithstanding the foregoing, the parties agree that the sole monetary damages
payable for a violation of the terms of this Agreement with respect to which additional amounts are expressly provided shall be such Additional Amount. Nothing shall preclude a Notice Holder or Holder
of Registrable Securities from pursuing or obtaining specific performance or other equitable relief with respect to this Agreement. 

        All
of the Company's and the Guarantor's obligations set forth in this Section 2(e) that are outstanding with respect to any Registrable Security at the time such security ceases
to be a Registrable Security shall survive until such time as all such obligations with respect to such security have been satisfied in full (notwithstanding termination of this Agreement pursuant to
Section 8(k)). 

        The
parties hereto agree that the Additional Amounts provided for in this Section 2(e) constitute a reasonable estimate of the damages that may be incurred by Holders of
Registrable Securities by reason of the failure of the Shelf Registration Statement to be filed or declared effective or available for effecting resales of Registrable Securities in accordance with
the provisions hereof. 

8

 

        SECTION
3.    Registration Procedures.    In connection with the registration obligations of the Company and the
Guarantor under Section 2 hereof, the Company and the Guarantor shall: 

        (a)   Before
filing any Registration Statement or Prospectus or any amendments or supplements (other than supplements that do nothing more substantive than name one or more
Notice Holders as selling security holders) thereto with the SEC, furnish to the Initial Purchaser copies of all such documents proposed to be filed and use reasonable efforts to reflect in each such
document when so filed with the SEC such comments as the Initial Purchaser reasonably shall propose within three (3) Business Days of the delivery of such copies to the Initial Purchaser. 

        (b)   Prepare
and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such Registration
Statement continuously effective for the applicable period specified in Section 2(a); cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and use reasonable efforts to comply with the provisions of the Securities Act
applicable to it with respect to the disposition of all securities covered by such Registration Statement during the Effectiveness Period in accordance with the intended methods of disposition by the
sellers thereof set forth in such Registration Statement as so amended or such Prospectus as so supplemented. 

        (c)   As
promptly as reasonably practicable give notice to the Notice Holders and the Initial Purchaser (i) when any Prospectus, Prospectus supplement, Registration
Statement or post-effective amendment to a Registration Statement has been filed with the SEC and, with respect to a Registration Statement or any post-effective amendment,
when the same has been declared effective, (ii) of any request, following the effectiveness of the Initial Shelf Registration Statement under the Securities Act, by the SEC or any other federal
or state governmental authority for amendments or supplements to any Registration Statement or related Prospectus or for additional information, (iii) of the issuance by the SEC or any other
federal or state governmental authority of any stop order or injunction suspending or enjoining the use of any Prospectus or the effectiveness of any Registration Statement or the initiation or
threatening of any proceedings for that purpose, (iv) of the receipt by the Company or the Guarantor of any notification with respect to the suspension of the qualification or exemption from
qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (v) of the occurrence of (but not the nature
of or details concerning) a Material Event (provided, however, that no notice by the Company or the Guarantor shall be required pursuant to this clause (v) in the event that either the Company
and the Guarantor promptly file a Prospectus supplement to update the Prospectus or the Company files a Current Report on Form 8-K or other appropriate Exchange Act report
that is incorporated by reference into the Registration Statement, which, in either case, contains the requisite information with respect to such Material Event that results in such Registration
Statement no longer containing any untrue statement of material fact or omitting to state a material fact necessary to make the statements contained therein not misleading) and (vi) of the
determination by the Company and the Guarantor that a post-effective amendment to a Registration Statement will 

9

 

be
filed with the SEC, which notice may, at the discretion of the Company and the Guarantor (or as required pursuant to Section 3(i)), state that it constitutes a Deferral Notice, in which
event the provisions of Section 3(i) shall apply. 

        (d)   Use
reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or the lifting of any suspension of the
qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in either case at the earliest possible
moment or, if any such order or suspension is made effective during any Deferral Period, at the earliest possible moment after the expiration of such Deferral Period. 

        (e)   If
reasonably requested by the Initial Purchaser or any Notice Holder, as promptly as reasonably practicable incorporate in a Prospectus supplement or
post-effective amendment to a Registration Statement such information as the Initial Purchaser or such Notice Holder shall, on the basis of an opinion of nationally recognized counsel
experienced in such matters, determine to be required to be included therein by applicable law and make any required filings of such Prospectus supplement or such post-effective amendment
as required by applicable law; provided that neither the Company nor the Guarantor shall not be required to take any actions under this
Section 3(e) that are not, in the reasonable opinion of counsel for the Company and the Guarantor, in compliance with applicable law. 

        (f)    As
promptly as reasonably practicable after the filing of such documents with the SEC, furnish to each Notice Holder and the Initial Purchaser, upon their request and
without charge, at least one (1) conformed copy of the Registration Statement and any amendment thereto, including financial statements, but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference and all exhibits (unless requested in writing to the Company by such Notice Holder or the Initial Purchaser, as the case may be). 

        (g)   During
the Effectiveness Period (except during such periods that a Deferral Notice is outstanding and has not been revoked), deliver to each Notice Holder in connection
with any sale of Registrable Securities pursuant to a Registration Statement, without charge, as many copies of the Prospectus or Prospectuses relating to such Registrable Securities and any amendment
or supplement thereto as such Notice Holder may reasonably request; and the Company and the Guarantor hereby consent (except during such periods that a Deferral Notice is outstanding and has not been
revoked) to the use of such Prospectus or each amendment or supplement thereto by each Notice Holder in connection with any offering and sale of the Registrable Securities covered by such Prospectus
or any amendment or supplement thereto in the manner set forth therein. 

        (h)   Subject
to Section 3(i), prior to any public offering of the Registrable Securities pursuant to the Shelf Registration Statement, use reasonable efforts to
register or qualify or cooperate with the Notice Holders in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for
offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Notice Holder reasonably requests in writing (which request may be 

10

 

included
in the Notice and Questionnaire), it being agreed that no such registration or qualification will be made unless so requested; prior to any public offering of the Registrable Securities
pursuant to the Shelf Registration Statement, use reasonable efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period in connection
with such Notice Holder's offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption therefrom) and do any and all other acts or things necessary to enable
the disposition in such
jurisdictions of such Registrable Securities in the manner set forth in the relevant Registration Statement and the related Prospectus; provided that
neither the Company nor the Guarantor will be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it is not otherwise qualified or
(ii) take any action that would subject it to general service of process in suits or to taxation in any such jurisdiction where it is not then so subject. 

        (i)    Upon
(A) the issuance by the SEC of a stop order suspending the effectiveness of the Shelf Registration Statement or the initiation of proceedings with respect to
the Shelf Registration Statement under Section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any fact (a "Material Event") as a result of which
any Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not
misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under
which they were made, not misleading (including, in any such case, as a result of the non-availability of financial statements), or (C) the occurrence or existence of any
development, event, fact, situation or circumstance relating to the Company or the Guarantor that, in the discretion of the Company and the Guarantor, makes it appropriate to suspend the availability
of the Shelf Registration Statement and the related Prospectus, (i) in the case of clause (B) above, subject to the next sentence, as promptly as practicable prepare and file a
post-effective amendment to such Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference or file any other required document that
would be incorporated by reference into such Registration Statement and Prospectus so that such Registration Statement does not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements therein not misleading, and such Prospectus does not contain any untrue statement of a material fact or omit to state
any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, as thereafter delivered to the purchasers of the Registrable
Securities being sold thereunder, and, in the case of a post-effective amendment to a Registration Statement, subject to the next sentence, use reasonable efforts to cause it to be
declared effective as promptly as is reasonably practicable, and (ii) give notice to the Notice Holders that the availability of the Shelf Registration Statement is suspended (a "Deferral
Notice") and, upon receipt of any Deferral Notice, each Notice Holder agrees not to sell any Registrable Securities pursuant to the Registration Statement until such Notice Holder's receipt of copies
of the supplemented or amended Prospectus provided for in clause (i) above, or until it is advised in writing by the Company that the Prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. The Company and the Guarantor will use reasonable efforts to ensure that the use of the
Prospectus may be resumed (x) in the case of clause (A) above, as 

11

 

promptly
as is practicable, (y) in the case of clause (B) above, as soon as, in the sole judgment of the Company and the Guarantor, public disclosure of such Material Event would not be
prejudicial to or contrary to the interests of the Company or the Guarantor or, if necessary to avoid unreasonable burden or expense, as soon as reasonably practicable thereafter and (z) in the
case of clause (C) above, as soon as, in the discretion of the Company and the Guarantor, such suspension is no longer
appropriate. So long as the period during which the availability of the Registration Statement and any Prospectus is suspended (the "Deferral Period") does not exceed thirty (30) days during
any three (3) month period or ninety (90) days during any twelve (12) month period, neither the Company nor the Guarantor shall not incur any obligation to pay Additional Amounts
pursuant to Section 2(e). 

        (j)    If
reasonably requested in writing in connection with a disposition of Registrable Securities pursuant to a Registration Statement, make reasonably available for
inspection during reasonable business hours by a representative for the Notice Holders of such Registrable Securities and any broker-dealers, attorneys and accountants retained by such Notice Holders,
all relevant financial and other records, pertinent corporate documents and properties of the Company, the Guarantor and their respective subsidiaries, and cause the appropriate executive officers,
directors and designated employees of the Company, the Guarantor and their respective subsidiaries to make reasonably available for inspection during normal business hours all relevant information
reasonably requested by such representative for the Notice Holders or any such broker-dealers, attorneys or accountants in connection with such disposition, in each case as is customary for similar
"due diligence" examinations; provided, however, that such persons shall first agree in writing with the Company or the Guarantor, as the case may be,
that any information that is reasonably designated by the Company or the Guarantor, as the case may be, in writing as confidential at the time of delivery of such information shall be kept
confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement, unless (i) disclosure of such information is required by court or
administrative order or is necessary to respond to inquiries of regulatory authorities; (ii) disclosure of such information is required by law (including any disclosure requirements pursuant to
federal securities laws in connection with the filing of any Registration Statement or the use of any Prospectus referred to in this Agreement), (iii) such information becomes generally
available to the public other than as a result of a disclosure or failure to safeguard by any such person or (iv) such information becomes available to any such person from a source other than
the Company or the Guarantor, as the case may be, and such source is not bound by a confidentiality agreement or otherwise obligated to keep such information confidential; and provided further that
the foregoing inspection and information gathering shall, to the greatest extent possible, be coordinated on behalf of all the Notice Holders and the other parties entitled thereto by the counsel
referred to in Section 5. 

        (k)   Comply
with all applicable rules and regulations of the SEC and make generally available to its security holders earning statements (which need not be audited)
satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than forty-five
(45) days after the end of any twelve (12)-month period (or ninety (90) days after the end of any twelve (12)-month period if such period is a fiscal year) commencing on the first day of
the first 

12

 

fiscal
quarter of the Company commencing after the effective date of a Registration Statement, which statements shall cover said twelve (12)-month periods. 

        (l)    Cooperate
with each Notice Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities sold pursuant to a Registration
Statement, and cause such Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names as such Notice Holder may request in writing at least two
(2) Business Days prior to any sale of such Registrable Securities. 

        (m)  Provide
a CUSIP number for all Registrable Securities covered by each Registration Statement not later than the effective date of such Registration Statement and provide
the Trustee for the Notes and the transfer agent for the Common Stock with certificates for the Registrable Securities that are in a form eligible for deposit with The Depository Trust Company. 

        (n)   Make
a reasonable effort to provide such information as is required for any filings required to be made with the National Association of Securities Dealers, Inc. 

        (o)   Upon
(i) the filing of the Initial Shelf Registration Statement and (ii) the effectiveness of the Initial Shelf Registration Statement, announce the same,
in each case by release to Businesswire, Reuters Economic Services, Bloomberg Business News or any other means of dissemination reasonably expected to make such information known publicly. 

        (p)   Take
all actions necessary, or reasonably requested by the holders of a majority of the Registrable Securities being sold, in order to expedite or facilitate disposition
of such Registrable Securities; provided that neither the Company nor the Guarantor shall be required to take any action in connection with an underwritten offering without its consent. 

        (q)   Cause
the Indenture to be qualified under the TIA not later than the effective date of any Registration Statement; and in connection therewith, cooperate with the
Trustee to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the TIA and execute, and use reasonable efforts to cause the
Trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely
manner. 

        SECTION
4.    Holder's Obligations.    Each Holder agrees, by acquisition of the Registrable Securities, that no
Holder of Registrable Securities shall be entitled to sell any of such Registrable Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto, unless such Holder has
furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(d) hereof (including the information required to be included in such Notice and Questionnaire) and the
information set forth in the next sentence. Each Notice Holder agrees promptly to furnish to the Company in writing all information required to be disclosed in order to make the information previously
furnished to the Company by such Notice Holder not misleading, any other information regarding such Notice Holder and the distribution of such Registrable Securities as may be required to be 

13

 

disclosed
in the Registration Statement under applicable law or pursuant to SEC comments and any information otherwise required by the Company to comply with applicable law or regulations. Each Holder
further agrees, following termination of the Effectiveness Period, to notify the Company, within ten (10) Business Days of a request, of the amount of Registrable Securities sold pursuant to
the Registration Statement and, in the absence of a response, the Company may assume that all of the Holder's Registrable Securities were so sold. 

        SECTION
5.    Registration Expenses.    The Company and the Guarantor shall bear all fees and expenses incurred in
connection with the performance by the Company and the Guarantor of their obligations under Sections 2 and 3 of this Agreement whether or not any of the Registration Statements are declared effective.
Such fees and expenses shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (x) with respect to filings required to
be made with the National Association of Securities Dealers, Inc. and (y) of compliance with federal and state securities or Blue Sky laws to the extent such filings or compliance are
required pursuant to this Agreement (including, without limitation, reasonable fees and disbursements of the counsel specified in the next sentence in connection with Blue Sky qualifications of the
Registrable Securities under the laws of such jurisdictions as the Notice Holders of a majority of the Registrable Securities being sold pursuant to a Registration Statement may designate)),
(ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities in a form eligible for deposit with The Depository Trust Company),
(iii) duplication expenses relating to copies of any Registration Statement or Prospectus delivered to any Holders hereunder, (iv) fees and disbursements of counsel for the Company and
the Guarantor in connection with the Shelf Registration Statement, and (v) reasonable fees and disbursements of the Trustee and its counsel and of the registrar and transfer agent for the
Common Stock. In addition, the Company and the Guarantor shall bear or reimburse the Notice Holders for the fees and disbursements of one firm of legal counsel for the Holders, which shall, upon the
written consent of the Initial Purchaser (which shall not be unreasonably withheld), be another nationally recognized law firm experienced in securities law matters designated by the Company. In
addition, the Company and the Guarantor shall pay their respective internal expenses (including, without limitation, all salaries and expenses of officers and employees performing legal or accounting
duties), and their respective expenses for any annual audit, the fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange on which the same
securities of the Company or the Guarantor, as the case may be, are then listed and the fees and expenses of any person, including special experts, retained by the Company or the Guarantor, as the
case may be. 

        SECTION
6.    Indemnification; Contribution.    

        (a)   The
Company and the Guarantor agree to indemnify and hold harmless the Initial Purchaser and each Holder of Registrable Securities and each person, if any, who controls
the Initial Purchaser or any holder of Registrable Securities within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, as follows: 

14

 

          (i)  against
any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were made, not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any
preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading; 

         (ii)  against
any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or
any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue
statement or omission, provided that (subject to Section 6(d) below) any such settlement is effected with the prior written consent of the Company; and 

        (iii)  subject
to Section 6(c) below, against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in
investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; 

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any
untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Initial Purchaser,
such Holder of Registrable Securities (which also acknowledges the indemnity provisions herein) or any person, if any, who controls the Initial Purchaser or any such Holder of Registrable Securities
expressly for use in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); provided
further that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense (1) arising from an offer or sale of Registrable Securities
occurring during a Deferral Period, if a Deferral Notice was given to such Notice Holder or (2) if the Holder fails to deliver at or prior to the written confirmation of sale, the most recent
Prospectus, as amended or supplemented, and such
Prospectus, as amended or supplemented, would have corrected such untrue statement or omission or alleged untrue statement or omission of a material fact and the delivery thereof was required by law. 

        (b)   In
connection with any Shelf Registration Statement in which a Holder, including, without limitation, the Initial Purchaser, of Registrable Securities is participating,
in furnishing information relating to such Holder of Registrable Securities to 

15

 

the
Company in writing expressly for use in such Registration Statement, any preliminary prospectus, the Prospectus or any amendments or supplements thereto, the holders of such Registrable Securities
agree, severally and not jointly, to indemnify and hold harmless the Initial Purchaser and each person, if any, who controls the Initial Purchaser within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act and the Company, the Guarantor and each person, if any, who controls the Company or the Guarantor within the meaning of either such Section,
against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished to the Company or the Guarantor by or on behalf of such Holder of Registrable Securities (which also acknowledges the
indemnity provisions herein) or any person, if any, who controls any such Holder of Registrable Securities expressly for use in the Registration Statement (or any amendment thereto) or such
preliminary prospectus or the Prospectus (or any amendment or supplement thereto). 

        The
Initial Purchaser agrees to indemnify and hold harmless the Company, the Guarantor, the Holders of Registrable Securities, and each person, if any, who controls the Company, the
Guarantor or any Holder of Registrable Securities within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon
and in conformity with written information furnished to the Company by or on behalf of the Initial Purchaser expressly for use in the Registration Statement (or any amendment thereto) or such
preliminary prospectus or the Prospectus (or any amendment or supplement thereto). 

        (c)   Each
indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action or proceeding commenced against it in respect of
which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially
prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of these indemnity provisions. The indemnifying party, upon request
of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such
proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain a separate firm
as its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually
agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and
representation of both parties by the same counsel would be 

16

 

inappropriate
due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction, be liable for (A) the reasonable fees and expenses of more than one firm (in addition to any local counsel) for
the Initial Purchaser, Holders of Registrable Securities, and all persons, if any, who control the Initial Purchaser or Holders of Registrable Securities within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act or (B) the reasonable fees and expenses of more than one firm (in addition to any local counsel) for the Company, the Guarantor,
their respective directors, and each person, if any, who controls the Company or the Guarantor within the meaning of either such Section, and that all such reasonable fees and expenses shall be
reimbursed as they are incurred. In the event a separate firm is retained for the Initial Purchaser, Holders of Registrable Securities, and control persons of the Initial Purchaser and Holders of
Registrable Securities, such firm shall be designated in writing by the Initial Purchaser. In the event a separate firm is retained for the Company and the Guarantor, and such directors, officers and
control persons of the Company and the Guarantor, such firm shall be designated in writing by the Company and the Guarantor. No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation,
proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 

        (d)   If
at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying
party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into
more than sixty (60) days after receipt by such indemnifying party of aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least
forty-five (45) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement; provided that an indemnifying party shall not be liable for any such settlement effected without its
consent if such indemnifying party (1) reimburses such indemnified party in accordance with such request to the extent it considers such request to be reasonable and (2) provides written
notice to the indemnified party describing any unpaid balance it believes is unreasonable and the reasons therefor, in each case prior to the date of such settlement. 

        (e)   If
the indemnification to which an indemnified party is entitled under this Section 6 is for any reason unavailable to or insufficient although applicable in
accordance with its terms to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, in such proportion as is appropriate 

17

 

to
reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such
losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. 

        The
relative fault of the Company and/or the Guarantor on the one hand and the holders of the Registrable Securities or the Initial Purchaser on the other hand shall be determined by
reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the
Company and/or the Guarantor or by the holder of the Registrable Securities or the Initial Purchaser and the parties' relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. 

        The
parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6(e) were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred to above in this Section 6(e). The aggregate amount of losses, liabilities, claims, damages, and expenses
incurred by an indemnified party and referred to above in this Section 6(e) shall be deemed to include any out-of-pocket legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. 

        Notwithstanding
the provisions of this Section 6, neither the Holder of any Registrable Securities nor the Initial Purchaser shall be required to indemnify or contribute any
amount in excess of the amount by which the total price at which the Registrable Securities sold by such Holder of Registrable Securities or by the Initial Purchaser, as the case may be, and
distributed to the public were offered to the public exceeds the amount of any damages that such Holder of Registrable Securities or the Initial Purchaser has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. 

        No
person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty
of such fraudulent misrepresentation. 

        For
purposes of this Section 6(e), each person, if any, who controls the Initial Purchaser or any holder of Registrable Securities within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchaser or such holder, and each person, if any, who controls the Company or the
Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. 

        SECTION
7.    Information Requirements.    The Company and the Guarantor covenants that, if at any time before the end
of the Effectiveness Period the Company is not subject to the reporting requirements of the Exchange Act, it will cooperate with any Holder 

18

 

of
Registrable Securities and take such further reasonable action as any Holder of Registrable Securities may reasonably request in writing (including, without limitation, making such reasonable
representations as any such Holder may reasonably request), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities
Act within the limitations of Rule 144 and Rule 144A under the Securities Act and customarily taken in connection with sales pursuant to such exemptions. Upon the written request of any
Holder of Registrable Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such filing requirements, unless such a statement has been included in
the Company's most recent annual or quarterly report required to be filed and filed pursuant to Section 13 or Section 15(d) of the Exchange Act. Notwithstanding the foregoing, nothing in
this Section 7 shall be deemed to require the Company to register any of its securities under any section of the Exchange Act. 

        SECTION
8.    Miscellaneous    

        (a)    No Conflicting Agreements.    The Company is not, and the Guarantor is not, as of the date hereof, a party to,
nor shall they, on or after the date of this Agreement, enter into, any agreement with respect to the Company's securities that conflicts with the rights granted to the Holders of Registrable
Securities in this Agreement. The Company and the Guarantor represent and warrant that the rights granted to the Holders of Registrable Securities hereunder do not in any way conflict with the rights
granted to the holders of the Company's or the Guarantor's securities under any other agreements. 

        (b)    Amendments and Waivers.    The provisions of this Agreement, including the provisions of this sentence, may not
be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company and the Guarantor have obtained the written consent of
Holders of a majority of the then outstanding Underlying Common Stock constituting Registrable Securities (with Holders of Notes or Semi-annual Coupon Notes deemed to be the Holders, for
purposes of this Section, of the number of outstanding shares of Underlying Common Stock into which such Notes or Semi-annual Coupon Notes are or would be convertible or exchangeable as of
the date on which such consent is requested). Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders of Registrable
Securities may be given by Holders of at least a majority of the Registrable Securities being sold by such Holders pursuant to such Registration Statement;  provided that the provisions of this sentence
may not be amended, modified, or supplemented except in accordance with the provisions of the immediately
preceding sentence. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or thereafter shall be bound by any such amendment,
modification, supplement, waiver or consent effected pursuant to this Section 8(b), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or
consent appears on the Registrable Securities or is delivered to such Holder. 

19

 

        (c)    Notices.    All notices and other communications provided for or permitted hereunder shall be made in writing
by hand delivery, by telecopier, by courier guaranteeing overnight delivery or by first-class mail, return receipt requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after being deposited with such courier, if made by overnight courier, or (iv) on the date
indicated on the notice of receipt, if made by first-class mail, to the parties as follows:

        (d)    Approval of Holders.    Whenever the consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company, the Guarantor or their Affiliates (other than the Initial Purchaser or subsequent Holders of Registrable Securities if
such subsequent Holders are deemed to be such affiliates solely by reason of their holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was
given by the Holders of such required percentage. 

        (e)    Successors and Assigns.    This Agreement shall inure to the benefit of and be binding upon the successors and
assigns of each of the parties hereto and, without requiring any express assignment, shall inure to the benefit of and be binding upon each Holder of any Registrable Securities;  provided that nothing
herein shall be deemed to permit any assignment, transfer of other disposition of Registrable Securities in violation of the terms
of the Purchase Agreement. If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be subject to
all of the terms of this Agreement and by taking and holding such Registrable Securities, such person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and
provisions of this Agreement. 

        (f)    Counterparts.    This Agreement may be executed in any number of counterparts and by the parties hereto in

NEW YORK. 

        (i)    Severability.    If any term, provision, covenant or restriction of this Agreement is held to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or
invalidated thereby, and the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term,
provision, covenant or restriction, it being intended that all of the rights and privileges of the parties hereto shall be enforceable to the fullest extent permitted by law. 

21

 

        (j)    Entire Agreement.    This Agreement is intended by the parties hereto as a final expression of their agreement
and is intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted
by the Company and the Guarantor with respect to the Registrable Securities. Except as provided in the Purchase Agreement, there are no restrictions, promises, warranties or undertakings, other than
those set forth or referred to herein, with respect to the registration rights granted by the Company and the Guarantor with respect to the Registrable Securities. This Agreement supersedes all prior
agreements and undertakings among the parties hereto with respect to such registration rights. 

        (k)    Termination.    This Agreement and the obligations of the parties hereunder shall terminate upon the expiration
of the Effectiveness Period, except for (i) any liabilities or obligations under Section 4, 5 or 6 hereof and the obligations to make payments of and provide for Additional Amounts under
Section 2(e) hereof to the extent such damages accrue prior to the end of the Effectiveness Period, each of which shall remain in effect in accordance with its terms.
