endorsements required by law, stock exchange or automated quotation system rule or regulation or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its
authentication. The Securities are being offered and sold by the Company pursuant to a Purchase Agreement dated March 24, 2008 (the “Purchase Agreement”) between the Company and the Purchaser, in transactions exempt from, or not
subject to, the registration requirements of the Securities Act. 
 (a) Restricted Global Securities. All of the Securities are
initially being offered and sold in reliance on exemptions from the registration requirements of the Securities Act and shall be issued initially in the form of one or more Restricted Global Securities, which shall be deposited on behalf of the
purchasers of the securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company (“DTC”, and such depositary, or any successor thereto, being hereinafter

TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES

Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security that has been authenticated and delivered by the Trustee.

Security) as a result of Payment-in-Kind Interest in an aggregate principal amount specified in such Company Order. The Company Order shall specify the amount of Securities to be authenticated, shall provide that all such Securities will be
represented by a Restricted Global Security and the date on which each original issue of Securities is to be authenticated. 
 (f) The
Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do
so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 (g) The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral
multiple thereof and, if PIK Interest is paid, in denominations of $1.00 or integral multiples of $1.00 (in each case in aggregate principal amount).

Paying Agent that is not also the Trustee.

this Indenture, provided that the Agent may be an Affiliate of 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 Agent not a
party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act

Paying Agent, it shall, before 12:00 p.m. (noon), New York City time, on each due date of the principal of, interest or Additional Interest on, any Securities, segregate the money and hold it as a separate trust fund. The Company at any time
may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums
so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money.

charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto; provided that this sentence shall not apply to any exchange pursuant to
Section 2.10, 2.12(a), 3.05, 4.02(e) or 11.05. 
 (b) Neither the Company, any Registrar nor the Trustee shall be required to exchange
or register a transfer of any Securities or portions thereof in respect of which a Fundamental Change Repurchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the
portion thereof not to be purchased).

the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange.

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.

their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them harmless, then, in the
absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its written request 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 principal amount, bearing a number not contemporaneously outstanding and the Guarantor shall execute a replacement Guarantee.

 (b) If 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, or converted pursuant to Article 4, the Company in its discretion may, instead of issuing a new Security, pay, purchase or convert such Security, as the case may be. 
 (c) Upon the issuance of any new Securities under this Section 2.07, 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 reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 
 (d) Every new Security or Guarantee issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security or Guarantee
shall constitute an original additional contractual obligation of the Company and the Guarantor, whether or not the mutilated, 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. 
 (e) The provisions of this
Section 2.07 are (to the extent lawful) 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.

for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding. 
 (b) If a
Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 (c) If a Paying Agent (other than the Company or an Affiliate of the Company) holds in respect of the outstanding Securities on a Fundamental Change
Repurchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if 

  

 15 

 
any) and accrued interest on Securities (or portions thereof) payable on that date, then on and after such Fundamental Change Repurchase Date or Final
Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding and cash interest on them shall cease to accrue.

owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and
that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. 
 Section 2.10 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities.
Temporary Securities shall be substantially in the form of definitive securities but may have variations that the Company with the consent of the Trustee considers appropriate for temporary Securities. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities. 
 Section 2.11
Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for transfer,
exchange, purchase, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, purchase, payment, conversion or cancellation and shall dispose of
the cancelled Securities in accordance with its customary procedures or deliver the canceled Securities to the Company upon its request therefor. All Securities which are purchased or otherwise acquired by the Company or any of its Subsidiaries
prior to the Final Maturity Date pursuant to Article 3 shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities or issue any new Securities to replace any such Securities or any Securities that
any Holder has converted pursuant to Article 4. 
 Section 2.12 Legend; Additional Transfer and Exchange Requirements.

 (a) If Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the
legends set forth on the forms of Securities attached as Exhibit A (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 

  

 16 

 
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 if requested by the Company or such Registrar, 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 under the Securities Act or that such Securities are not “restricted” within the meaning of Rule 144 under the Securities Act; provided that no such evidence need be supplied in
connection with the sale of such Security pursuant to a registration statement that is effective at the time of such sale. Upon (1) provision of such satisfactory evidence if requested, or (2) 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, at the written direction of the Company, 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 Legend shall be reinstated. 
 (b) 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 the foregoing 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. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance
with this Section 2.12. 
 (c) Subject to Section 2.12(b) and in compliance with Section 2.12(d), every Security shall be
subject to the restrictions on transfer provided in the Legend. Whenever any Restricted Security other than a Restricted Global Security is presented or surrendered for registration of transfer or in 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 A, 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 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to
sales thereof under Rule 144 under the Securities Act (or any successor provision). 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 or any
successor provision, by, if requested by the Company or the Registrar, an Opinion of Counsel reasonably acceptable to the Company and the Registrar and addressed to the Company and the Registrar, to the effect that the transfer of such Security has
been made in compliance with Rule 144 or such successor provision), be exchanged for a new 

  

 17 

 
Security, of like tenor and aggregate 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 offer and sale of the Securities under the Securities Act. The Trustee 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. 
 As used in Sections 2.12(c) and (d), the term “transfer” encompasses any sale,
pledge, transfer, hypothecation or other disposition of any Security. 
 (e) The provisions below shall apply only to Global Securities:

 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and
delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for purposes of this Indenture. 
 (2) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered, and no transfer of a Global Security in whole or in
part shall be 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 (A) 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 after receiving such notice or becoming aware that the Depositary has ceased to be a “clearing agency,” or (B) an Event of Default has occurred and is continuing with
respect to the Securities. Any Global Security exchanged pursuant to subclause (A) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to subclause (B) above 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 further 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. 
 (3) 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 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 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 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. 
  

 18 

 (4) Subject to clause (6) of this Section 2.12(e), the registered Holder may grant proxies and
otherwise authorize any Person, including Agent Members 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. 
 (5) In the event of the occurrence of any of the events specified in clause (2) of this Section 2.12(e), the Company will promptly make
available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 
 (6) Neither 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 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. 
 (7) At such time as all interests in a Global Security have been converted, cancelled or exchanged for Securities
in certificated form, such Global Security shall, upon receipt thereof, be cancelled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Securities Custodian, subject to Section 2.11 of
this Indenture. At any time prior to such cancellation, if any interest in a Global Security is converted, canceled or exchanged for Securities in certificated form, the principal amount of such Global Security shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Securities Custodian, be appropriately reduced, and an endorsement shall be made on such Global Security, by the Trustee or the Securities Custodian, at the direction of the
Trustee, to reflect such reduction. 
 (f) Until the expiration of the holding period applicable to sales thereof under Rule 144 under
the Securities Act (or any successor provision thereto), any stock certificate representing Common Stock issued upon conversion of any Security shall bear a legend in substantially the following form, unless such Common Stock has been sold pursuant
to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or transferred in compliance with Rule 144 under the Securities Act (or any successor
provision thereto), or such Common Stock has been issued upon conversion of Securities that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act or pursuant to Rule 144 under the
Securities Act (or any successor provision thereto), or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent:

 “THE SECURITIES REPRESENTED HEREBY (THE “SECURITIES”) HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) NOR REGISTERED OR QUALIFIED UNDER THE SECURITIES OR BLUE SKY LAWS OF ANY STATE. THE SECURITIES MAY ONLY BE SOLD (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF,
(B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON THE TRANSFEROR REASONABLY BELIEVES IS A QUALIFIED
INSTITUTIONAL BUYER, AS DEFINED IN RULE 144A, THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, OR (D) PURSUANT TO ANY
OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF
COUNSEL, CERTIFICATIONS AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THESE RESTRICTIONS SHALL APPLY UNTIL SUCH SECURITIES MAY BE RESOLD WITHOUT RESTRICTION PURSUANT TO RULE 144 UNDER THE ACT. 
 UNLESS PERMITTED UNDER CANADIAN SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY IN CANADA BEFORE AUGUST 2, 2008.

 Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the
conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the restrictive legend required by this section. The Trustee may reasonably rely on an Opinion of Counsel in order to
determine whether the legend is required upon transfer. 
 Section 2.13 CUSIP Numbers. The Company in issuing the Securities may
use one or more “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of purchase 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 purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase
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 
 PURCHASE 
 Section 3.01 Repurchase of Securities at Option of the Holder upon a Fundamental
Change. 
 (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security shall have the right, at the
option of the Holder, to require the Company to repurchase for cash all or any portion of the Securities of such Holder equal to $1,000 principal amount (or an integral multiple thereof), or if Payment-in-Kind Interest is paid, a minimum of $1.00 or
an integral multiple of $1.00, at the Fundamental Change Repurchase Price, on the date that is not less than 30 days nor more than 45 days after the date of the Fundamental Change Company Notice pursuant to subsection 3.01(b) (the
“Fundamental Change Repurchase Date”). 
 (b) As promptly as practicable following the date on which the Company publicly announces
such transaction, but in no event less than 20 days prior to the anticipated effective date of a Fundamental Change, the Company shall mail a written notice of the Fundamental Change and of the resulting repurchase right to the Trustee, Paying Agent
and to each Holder (and to beneficial owners as required by applicable law) (the “Fundamental Change Company Notice”). The Fundamental Change Company Notice shall include the form of a Fundamental Change Repurchase Notice to be completed
by the Holder and shall state: 
 (1) the events causing such Fundamental Change; 
 (2) the date (or expected date) of such Fundamental Change; 
 (3) the last date by which the Fundamental Change Repurchase Notice must be delivered to elect the repurchase option pursuant to this Section 3.01;

 (5) the Fundamental Change Repurchase Price; 
 (6) the Holder’s right to require the Company to purchase the Securities;

 (7) the name and address of each Paying Agent and Conversion Agent; 
 (8) the then effective Conversion Rate and any adjustments to the Conversion Rate resulting from such Fundamental Change; 
 (9) the procedures that the Holder must follow to exercise conversion rights under Article 4 and that Securities as to which a Fundamental Change
Repurchase Notice has been given may be converted into Common Stock pursuant to Article 4 of this Indenture only to the extent that the Fundamental Change Repurchase Notice has been withdrawn in accordance with the terms of this Indenture;

  

 21 

 (10) the procedures that the Holder must follow to exercise rights under this Section 3.01;

 (11) the procedures for withdrawing a Fundamental Change Repurchase Notice; 
 (12) that, unless the Company fails to pay such Fundamental Change Repurchase Price, Securities covered by any Fundamental Change Repurchase Notice will
cease to be outstanding and interest and Additional Interest, if any, will cease to accrue on and after the Fundamental Change Repurchase Date; and 
 (13) the CUSIP number of the Securities. 
 At the Company’s request, the Trustee shall give such
Fundamental Change Company Notice in the Company’s name and at the Company’s expense; provided, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. If any of the Securities is in the
form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global Securities. 
 (c) A Holder may exercise its rights specified in Section 3.01(a) upon delivery of a written notice (which shall be in substantially the form
attached as Exhibit A under the heading “Fundamental Change Repurchase Notice” and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of
Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change Repurchase Notice”) to the Company or any Paying
Agent at any time prior to the close of business on the Business Day next preceding the Fundamental Change Repurchase Date, subject to extension to comply with applicable law. 
 (1) The Fundamental Change Repurchase Notice shall state: (A) the certificate number (if such Security is held other than in global form) of the
Security which the Holder will deliver to be purchased (or, if the Security is held in global form, any other items required to comply with the Applicable Procedures), (B) the portion of the principal amount of the Security which the Holder
will deliver to be purchased, in integral multiples of $1,000 or of $1.00, as applicable, and (C) that such Security shall be purchased as of the Fundamental Change Repurchase Date pursuant to the terms and conditions specified in the
Securities and in this Indenture. 
 (2) The delivery of a Security for which a Fundamental Change Repurchase Notice has been timely
delivered to any Paying Agent and not validly withdrawn prior to, on or after the Fundamental Change Repurchase Date (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of
the Fundamental Change Repurchase Price therefor. 
 (3) The Company shall only be obliged to purchase, pursuant to this Section 3.01,
a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000, or if Payment-in-Kind Interest is paid, $1.00 or an integral multiple of $1.00 (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). 
  

 22 

 (4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 3.01(c) shall have the right to withdraw such Fundamental Change Repurchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral
multiple thereof, or if Payment-in-Kind Interest is paid, a principal amount of $1.00 or an integral multiple thereof, at any time prior to the close of business on the Business Day prior to the Fundamental Change Repurchase Date by delivery of a
written notice of withdrawal to the Paying Agent in accordance with Section 3.02. 
 (5) A Paying Agent shall promptly notify the
Company of the receipt by it of any Fundamental Change Repurchase Notice or written withdrawal thereof. 
 (6) Anything herein to the
contrary notwithstanding, in the case of Global Securities, any Fundamental Change Repurchase Notice may be delivered or withdrawn and such Securities may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in
effect from time to time. 
 Section 3.02 Effect of Fundamental Change Repurchase Notice. 
 (a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Repurchase Notice from a Holder, the Holder of the Security in respect of
which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental Change Repurchase Notice is withdrawn as specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Repurchase Price with
respect to such Security, subject to the occurrence of the Fundamental Change Effective Date and an absence of an Event of Default, or a continuation thereof (other than a Default in the payment of the Fundamental Change Repurchase Price). Such
Fundamental Change Repurchase Price shall be paid to such Holder promptly following the later of (1) the Fundamental Change Repurchase Date (provided that the conditions in Section 3.01 have been satisfied) and (2) the time of
delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted into
shares of Common Stock pursuant to Article 4 on or after the date of the delivery of such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn in accordance with
Section 3.02(b) with respect to the Securities to be converted. 
 (b) A Fundamental Change Repurchase Notice may be withdrawn by means
of a written notice (which may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with
the Applicable Procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately prior to the Fundamental Change Repurchase Date, specifying (1) the principal amount
of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof, provided, however, that if Payment-in-Kind 

  

 23 

 
Interest is paid, the principal amount may equal $1.00 or an integral multiple of $1.00) with respect to which such notice of withdrawal is being submitted,
(2) if certificated Securities have been issued, the certificate number of the Security being withdrawn in whole or in withdrawable part (or if the Securities are not certificated, such written notice must comply with the Applicable Procedures)
and (3) the portion of the principal amount of the Security that will remain subject to the Fundamental Change Repurchase Notice, which portion must be a principal amount of $1,000 or an integral multiple thereof, provided, however, that if
Payment-in-Kind Interest is paid, the principal amount may equal a minimum of $1.00 or an integral multiple of $1.00. 
 Section 3.03
Deposit of Fundamental Change Repurchase Price. 
 (a) On or before 12:00 p.m. (noon) New York City time on the Business Day
following the applicable Fundamental Change Repurchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as
provided in Section 2.04) an amount of money (in immediately available funds if deposited on or after such Fundamental Change Repurchase Date), sufficient to pay the aggregate Fundamental Change Repurchase Price of all the Securities or
portions thereof that are to be purchased as of such Fundamental Change Repurchase Date. 
 (b) If a Paying Agent or the Trustee holds, in
accordance with the terms hereof, money sufficient to pay the Fundamental Change Repurchase Price of any Security for which a Fundamental Change Repurchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on the
Business Day following the applicable Fundamental Change Repurchase Date, such Security will cease to be outstanding, whether or not the Security is delivered to the Paying Agent or the Trustee, and interest and Additional Interest, if any, shall
cease to accrue, and the rights of the Holder in respect of the Security shall terminate (other than the right to receive the Fundamental Change Repurchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities
repurchased on or as soon as practicable after the Fundamental Change Repurchase Date. 
 (c) The Paying Agent will promptly return to the
respective Holders thereof any Securities with respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with this Indenture. 
 (d) If a Fundamental Change Repurchase Date falls after a Regular Record Date and on or before the related Interest Payment Date, then interest on the Securities payable on such Interest Payment Date will be payable
to the Holders in whose names the Securities are registered at the close of business on such Regular Record Date. 
 Section 3.04
Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.03 exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof that the Company
is obligated to purchase, then promptly after the Fundamental Change Repurchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company. 
  

 24 

 Section 3.05 Securities Purchased in Part. Any Security that is to be purchased only in part
shall be surrendered at the office of a Paying Agent, and promptly after the Fundamental Change Repurchase Date, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new
Security or Securities, of such authorized denomination or denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or any integral thereof, provided, however, that if Payment-in-Kind Interest is paid, the
principal amount may equal a minimum of $1.00 or an integral multiple of $1.00), in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 
 Section 3.06 Compliance with Securities Laws upon Purchase of Securities. In connection with any offer to purchase of Securities under
Section 3.01, the Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor to either such Rule), and any other tender offer rules, if applicable, under the Exchange Act, (b) file the related Schedule TO (or
any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit
the rights of the Holders and obligations of the Company under Sections 3.01 through 3.04 to be exercised in the time and in the manner specified therein. To the extent that compliance with any such laws, rules and regulations would result in a
conflict with any of the terms hereof, this Indenture is hereby modified to the extent required for the Company to comply with such laws, rules and regulations. 
 Section 3.07 Purchase of Securities in Open Market. The Company will surrender any Security purchased by the Company pursuant to this Article 3 to the Trustee for cancellation. Any securities
surrendered to the Trustee for cancellation will be canceled promptly in accordance with Section 2.11. The Company may repurchase Securities in the open market, by tender at any price or by negotiated transactions. 
 ARTICLE 4 
 CONVERSION 

Section 4.01 Conversion Privilege and Conversion Rate. 
 (a) Subject to and upon compliance with the provisions of this Article 4, at the option of the Holder thereof, any Security or portion thereof that is an integral multiple of $1,000 principal amount (or if
Payment-in-Kind interest is paid, in an integral multiple of $1,000) may be converted into fully paid and non-assessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at any time prior to the close of
business on the Business Day immediately preceding the Final Maturity Date, unless purchased by the Company at the Holder’s option, at the Conversion Rate in effect at such time, determined as hereinafter provided. 
 (b) Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security. 
 (c) A Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities into Common Stock,
and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 4. 
  

 25 

 (d) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(e) and
Section 4.06. 
 (e) By delivering the number of shares of Common Stock issuable on conversion to the Trustee, or to the Conversion
Agent, if the Conversion Agent is other than the Trustee, the Company will be deemed to have satisfied its obligation to pay the principal amount of the Securities so converted and its obligation to pay accrued and unpaid interest, and Additional
Interest if any, attributable to the period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than cancelled, extinguished or forfeited). 
 (f) Notwithstanding anything contained herein to the contrary, the Company shall not be obligated to deliver shares of Common Stock in connection with
any conversion of Securities to the extent such delivery would, in the Company’s reasonable judgment, after having received the advice of independent legal counsel (who may be the Company’s regularly engaged independent legal counsel),
constitute a violation of any Antitrust Laws; provided, however, that this Section 4.01(f) shall not limit the Company’s obligations under Section 7.5 of the Purchase Agreement. 
 Section 4.02 Conversion Procedure. 
 (a) To convert a Security, a Holder must (1) complete and manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent, (2) surrender the Security to a Conversion Agent,
(3) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (4) pay all transfer or similar taxes, if required pursuant to Section 4.04. The date on which the Holder satisfies all
of those requirements is the “Conversion Date.” Upon the conversion of a Security, the Company will pay the cash and deliver the shares of Common Stock, to the Trustee (or to the Conversion Agent, if the Conversion Agent is other than the
Trustee), as applicable, as promptly as practicable after the later of the Conversion Date and the date that all calculations necessary to make such payment and delivery have been made, but in no event later than five Business Days after the later
of those dates. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may be surrendered for conversion in accordance with the Applicable Procedures as in effect
from time to time. 
 (b) The person in whose name the shares of Common Stock are issuable upon conversion shall be deemed to be a holder of
record of such Common Stock on the Conversion Date; provided, however, that no surrender of a Security on any Conversion 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 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; provided further that such conversion shall be at the 

  

 26 

 
Conversion Rate in effect on the Conversion Date 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. Except as set forth in this Indenture, no payment or adjustment will be made for dividends or distributions declared or made on shares of Common Stock issued upon conversion of a Security prior to
the issuance of such shares. 
 (c) Holders of Securities surrendered for conversion (in whole or in part) during the period from the close
of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date will receive the semi-annual interest payable on such Securities on the corresponding Interest Payment Date notwithstanding the
conversion. Upon surrender of any such Securities for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date, unless (1) such Securities have
been surrendered for conversion following the Regular Record Date immediately preceding the final interest payment date (April 15, 2013), (2) the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record
Date and on or prior to the Business Day following the corresponding Interest Payment Date, or (3) to the extent of overdue interest, if any, which exists at the time of the Conversion with respect to such Security, such Securities shall also
be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will be made for
accrued interest on a converted Security. 
 (d) Subject to Section 4.02(c), nothing in this Section shall affect the right of a Holder
in whose name any Security is registered at the close of business on a Regular Record Date to receive the interest payable on such Security on the related Interest Payment Date in accordance with the terms of this Indenture, the Securities and the
Registration Rights Agreement. If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the conversion, if any, (and the amount of any cash in lieu of fractional shares pursuant to
Section 4.03) shall be based on the aggregate principal amount of all Securities so converted. 
 (e) In the case of any Security which
is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, without service charge, a new Security or Securities of authorized denominations in an aggregate
principal amount equal to, and in exchange for, the unconverted portion of the principal amount of such Security. A Security may be converted in part, but only if the principal amount of such part is an integral multiple of $1,000 and the principal
amount of such Security to remain outstanding after such conversion is equal to $1,000 or any integral multiple of $1,000 in excess thereof. 
 Section 4.03 Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number
of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. In lieu of any fractional share,
the Company will pay an amount in cash for the current market value of the fractional share. The current market value of a fractional share shall be determined (calculated to 

  

 27 

 
the nearest 1/100th of a share) by multiplying the average of the Closing Price of the Common Stock on the Trading Day immediately preceding the Conversion
Date by such fractional share and rounding the product to the nearest whole cent. 
 Section 4.04 Taxes on Conversion. If a
Holder converts a Security, the Holder shall pay any transfer, stamp or similar taxes or duties related to the issue or delivery of shares of Common Stock upon such conversion. The Holder shall also pay any such tax with respect to cash received in
lieu of fractional shares. In addition, 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. The Conversion Agent may refuse to deliver the certificate
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 than the Holder’s
name. Nothing herein shall preclude any tax withholding required by law or regulation. 
 Section 4.05 Company to Provide Stock.

 (a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its
authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock. 
 (b) All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive or
similar rights and free of any lien or adverse claim as the result of any action by the Company. 
 (c) The Company will endeavor promptly to
comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities. 
 Section 4.06 Adjustment of Conversion Rate. 
 (a) The Conversion Rate shall be adjusted from time to time by the Company
as follows: 
 (1) If the Company shall pay a dividend or make a distribution on outstanding Common Stock in shares of Common Stock, the
Conversion Rate in effect immediately prior to the record date for the determination of shareholders entitled to receive such dividend or other distribution shall be increased so that the same shall equal the rate determined by the Company by
multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which the numerator shall be the sum of the number of shares of Common Stock outstanding at the close of business on such record date plus the total
number of shares of Common Stock constituting such dividend or other distribution and of which the denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date. Such adjustment shall be made
successively whenever any such dividend or distribution is made and shall become effective immediately after such record date. For the purpose of this clause (1), the number of shares of Common Stock at any time outstanding shall 

  

 28 

 
not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on Common Stock held in the treasury
of the Company. If any dividend or distribution of the type described in this clause is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared. 
 (2) If the Company shall subdivide its outstanding Common Stock into a greater number of shares, or
combine its outstanding Common Stock into a smaller number of shares, the Conversion Rate in effect immediately prior to the day upon which such subdivision or combination becomes effective shall be, in the case of a subdivision of Common Stock,
proportionately increased and, in the case of a combination of Common Stock, proportionately reduced. Such adjustment shall be made successively whenever any such subdivision or combination of the Common Stock occurs and shall become effective
immediately after the date upon which such subdivision or combination becomes effective. 
 (3) If the Company shall issue certain rights or
warrants to all or substantially all holders of its outstanding Common Stock entitling them (for a period expiring within 45 days after such issuance) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock)
at a price per share (or having a conversion price per share) less than the Current Market Price per share of Common Stock (as determined in accordance with clause (9) of this Section 4.06(a)) on the record date for the determination of
shareholders entitled to receive such rights or warrants, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to
such record date by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on such record date plus the number of additional shares of Common Stock that such rights or warrants entitle
holders thereof to subscribe for or purchase (or into which such convertible securities are convertible) and of which the denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date plus the
number of shares which the aggregate offering price of the total number of shares of Common Stock so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered for subscription or purchase, which
shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at
the Current Market Price per share of Common Stock on such record date. Such adjustment shall be made successively whenever any such rights or warrants (or convertible securities) are issued, and shall become effective immediately after such record
date. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. If such rights or warrants
are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if the record date for the determination of shareholders entitled to receive such rights or warrants had not been fixed. In
determining whether any rights or warrants entitle the shareholders to subscribe for or purchase shares of Common Stock at a price less than the Current Market Price per share of Common 

  

 29 

 
Stock and in determining the aggregate offering price of the total number of shares of Common Stock so offered, there shall be taken into account any
consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 (4) If the Company shall make a dividend or other distribution to all or substantially all holders of its Common Stock of Capital Stock, other than
Common Stock, or evidences of indebtedness or other assets of the Company, including securities (excluding (x) any issuance of rights or warrants for which an adjustment was made pursuant to Section 4.06(a)(3), (y) dividends or
distributions in connection with a reclassification, consolidation, merger, combination, sale or conveyance resulting in a change in the conversion consideration pursuant to Section 4.10, or pursuant to any Rights Plan or (z) any dividend
or distribution paid exclusively in cash for which an adjustment was made pursuant to Section 4.06(a)(6)) (the “Distributed Securities”), then in each such case (unless the Company distributes such Distributed Securities for
distribution to the Holders of Securities on such dividend or distribution date as if each Holder had converted such Security into Common Stock immediately prior to the record date with respect to such distribution) the Conversion Rate in effect
immediately prior to the record date fixed for the determination of shareholders entitled to receive such dividend or distribution shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect
immediately prior to such record date by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on such record date and of which the denominator shall be Current Market Price per share on such record date
less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) on
such record date of the portion of the Distributed Securities so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on such record date). Such
adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. In the event that such dividend or
distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 If the fair market value (as so determined) of the portion of the Distributed Securities so distributed applicable to one share of Common Stock is equal
to or greater than the Current Market Price per share of the Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of a Security shall have the right to receive upon conversion
the amount of Distributed Securities so distributed that such Holder would have received had such Holder converted each Security on such record date. If the Board of Directors determines the fair market value of any distribution for purposes of this
Section 4.06(a)(4) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock.

 Notwithstanding the foregoing, if the securities distributed by the Company to all holders of its Common Stock consist of Capital Stock
of, or similar equity interests in, a Subsidiary or 

  

 30 

 
other business unit of the Company (the “Spinoff Securities”), the Conversion Rate shall be adjusted, unless the Company makes an equivalent
distribution to the Holders of the Securities, so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the record date fixed for the determination of shareholders entitled to receive such distribution
by a fraction, the numerator of which shall be the sum of (A) the average Closing Price of one share of Common Stock over the ten consecutive Trading Day period (the “Spinoff Valuation Period”) commencing on and including the fifth
Trading Day after the date on which ex-dividend trading commences for such distribution on the New York Stock Exchange or such other U.S. national or regional exchange or market on which the Common Stock is then listed or quoted and (B) the
average of the Closing Prices over the Spinoff Valuation Period of the Spinoff Securities multiplied by the number of Spinoff Securities distributed in respect of one share of Common Stock and the denominator of which shall be the average Closing
Price of one share of Common Stock over the Spinoff Valuation Period, such adjustment to become effective immediately prior to the opening of business on the fifteenth Trading Day after the date on which ex-dividend trading commences; provided,
however, that the Company may in lieu of the foregoing adjustment elect to make adequate provision so that each Holder of Securities shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such Holder of
Securities would have received if such Securities had been converted on the record date with respect to such distribution. 
 (5) With
respect to any rights or warrants (the “Rights”) that may be issued or distributed pursuant to any rights plan that the Company implements after the date of this Indenture (a “Rights Plan”), to the extent that such Rights Plan is
in effect upon such conversion, the Holders of Securities will receive, with respect to the shares of Common Stock issued upon conversion, the Rights described therein (whether or not the Rights have separated from the Common Stock at the time of
conversion), subject to the limitations set forth in and in accordance with any such Rights Plan; provided that, if, at the time of conversion, however, the Rights have separated from the shares of Common Stock in accordance with the provisions of
the Rights Plan so that Holders would not be entitled to receive any rights in respect of the shares of Common Stock issuable upon conversion of the Securities as a result of the timing of the Conversion Date, the Conversion Rate will be adjusted as
if the Company distributed to all holders of Common Stock Distributed Securities constituting such rights as provided in the first paragraph of clause (4) of this Section 4.06(a), subject to appropriate readjustment in the event of the
expiration, termination, repurchase or redemption of the Rights. Any distribution of rights or warrants pursuant to a Rights Plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute
a distribution of rights or warrants pursuant to this Section 4.06(a). Other than as specified in this clause (5) of this Section 4.06(a), there will not be any adjustment to the Conversion Rate as the result of the issuance of any
Rights, the distribution of separate certificates representing such Rights, the exercise or redemption of such Rights in accordance with any Rights Plan or the termination or invalidation of any Rights. 
 (6) If the Company shall, by dividend or otherwise, at any time distribute (a “Triggering Distribution”) to all holders of its Common Stock a
payment consisting exclusively of cash (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary) the Conversion Rate shall be increased so that the same
shall equal the rate determined by multiplying such 

  

 31 

 
Conversion Rate in effect immediately prior to the close of business on the record date for such Triggering Distribution (a “Determination Date”)
by a fraction of which the numerator shall be such Current Market Price per share of the Common Stock on the Determination Date and the denominator of which shall be the Current Market Price per share of the Common Stock on the Determination Date
less the amount of such cash dividend or distribution applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on the Determination Date), such increase to become
effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. If the amount of cash dividend or distribution applicable to one share of Common Stock is equal to or greater than the
Current Market Price per share of the Common Stock on the Determination Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of a Security shall have the right to receive upon conversion the amount of cash
so distributed that such Holder would have received had such Holder converted each Security on such Determination Date. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the
Conversion Rate that would then be in effect if such divided or distribution had not been declared. 
 (7) If any tender offer made by the
Company or any of its Subsidiaries for all or any portion of Common Stock shall expire, then, if the tender offer shall require the payment to shareholders of consideration per share of Common Stock having a fair market value (determined as provided
below) that exceeds the Closing Price per share of Common Stock on the Trading Day next succeeding the last date (the “Expiration Date”) tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at
which such tenders could have been made on the Expiration Date is hereinafter sometimes called the “Expiration Time”), the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion
Rate in effect immediately prior to the close of business on the Expiration Date by a fraction of which the numerator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value as determined in good
faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) payable to shareholders based on the acceptance (up
to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and
(B) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the Closing Price per share of Common Stock on the Trading
Day next succeeding the Expiration Date and the denominator of which shall be the product of the number of shares of Common Stock outstanding (including Purchased Shares but excluding any shares held in the treasury of the Company) at the Expiration
Time multiplied by the Closing Price per share of the Common Stock on the Trading Day next succeeding the Expiration Date, such increase to become effective immediately prior to the opening of business on the day following the Expiration Date. In
the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the
Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon the number of shares actually purchased, if any. If the application of this clause (7) of Section 4.06(a) to any tender offer
would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this clause (7). 
  

 32 

 (8) For purposes of this Section 4.06, the term “tender offer” shall mean and include
both tender offers and exchange offers, all references to “purchases” of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to
exchange offers, and all references to “tendered shares” (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. 
 (9) For purposes of any computation under this Section 4.06, “Current Market Price” shall mean the average of the daily Closing Prices
per share of Common Stock for each of the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if 
 (A) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4),
(5), (6) or (7) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by dividing such Closing Price by the same fraction by which
the Conversion Rate is so required to be adjusted as a result of such other event; 
 (B) the “ex” date for any event (other than
the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4), (5), (6) or (7) occurs on or after the “ex” date for the issuance or
distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Closing Price by the reciprocal of the
fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; and 
 (C) the “ex” date for
the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to the immediately preceding clause (A) or (B) of this Section 4.06(a)(9), the Closing
Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined in good faith by the Board of Directors in a manner consistent with any determination
of such value for purposes of Section 4.06(a)(4) or (7), whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share
of Common Stock as of the close of business on the day before such “ex” date. 
 For purposes of any computation under
Section 4.06(a)(7), if the “ex” date for any event (other than the tender offer that is the subject of the adjustment pursuant to Section 4.06(a)(7)) that requires an adjustment to the Conversion Rate pursuant to
Section 4.06(a)(1), (2), (3), (4), (5) or (6) occurs on the date of the Expiration Time for the tender or exchange offer requiring such computation or on the Trading Day next following the Expiration Time, the Closing Price for each
Trading Day on and after the “ex” date for such other event shall be adjusted by 

  

 33 

 
dividing such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For
purposes of this Section 4.06(a)(9) the term “ex” date, when used: 
 (A) with respect to any issuance or distribution, means
the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution; 
 (B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such
exchange or in such market after the time at which such subdivision or combination becomes effective, and 
 (C) with respect to any tender
or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. 
 Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 4.06, such adjustments shall be made to the Current Market Price as may be necessary
or appropriate to effectuate the intent of this Section 4.06 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors and evidenced by an Officers’ Certificate delivered to the Trustee. 

(b) In any case in which this Section 4.06 shall require that an adjustment be made following a record date, a Determination Date or Expiration
Date, as the case may be, established for the purposes specified in this Section 4.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in
Section 4.08) issuing to the Holder of any Security converted after such record date, Determination Date or Expiration Date the shares of Common Stock and other Capital Stock of the Company issuable upon such conversion over and above the
shares of Common Stock and other Capital Stock of the Company (or other cash, property or securities, as applicable) issuable upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of any cash, property or
securities the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such cash, property or securities. If any
distribution in respect of which an adjustment to the Conversion Rate is required to be made as of the record date, Determination Date or Expiration Date therefore is not thereafter made or paid by the Company for any reason, the Conversion Rate
shall be readjusted to the Conversion Rate which would then be in effect if such record date had not been fixed or such record date, Determination Date or Expiration Date had not occurred. 
 (c) For purposes of this Section 4.06, “record date” shall mean, with respect to any dividend, distribution or other transaction or event
in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged or converted into any combination of cash, securities or other property,
the date fixed for determination of shareholders entitled to receive such cash, security or other property (whether or not such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  

 34 

 (d) If one or more event occurs requiring an adjustment be made to the Conversion Rate for a particular
period, adjustments to the Conversion Rate shall be determined by the Company’s Board of Directors to reflect the combined impact of such Conversion Rate adjustment events, as set out in this Section 4.06, during such period. 

Section 4.07 No Adjustment. 
 (a) No adjustment in the Conversion Rate shall be required if Holders may participate in the transactions set forth in Section 4.06 above (to the same extent as if the Securities had been converted into Common Stock immediately prior
to such transactions) without converting the Securities held by such Holders. 
 (b) No adjustment in the Conversion Rate shall be required
unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which would be required to be made but for this Section 4.07(b) shall be carried
forward and taken into account in any subsequent adjustment. The Company shall adjust for any carry forward amount upon conversion regardless of the 1% threshold. All calculations under this Article 4 shall be made to the nearest cent or to the
nearest one-ten thousandth of a share, as the case may be, with one half cent and 0.00005 of a share, respectively, being rounded upward. 
 (c) No adjustment in the Conversion Rate shall be required for issuances of Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for a change in the par value, or a change to no par value, of the Common
Stock. Except as expressly provided in Section 4.06, no adjustment in the Conversion Rate shall be required for issuances of Common Stock or any securities convertible into, exercisable into or exchangeable for Common Stock, including the
issuance of Common Stock or options to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company, upon the issuance of Common Stock pursuant to any option,
warrant or right, or exercise of any exchangeable or convertible security outstanding as of the Issue Date, and repurchases by the Company of Common Stock not expressly discussed in this Article 4. 
 (d) To the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash.

 Section 4.08 Notice of Adjustment. Whenever the Conversion Rate or conversion privilege is required to be adjusted pursuant to
this Indenture, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Failure to mail such
notice or any defect therein shall not affect the validity of any such adjustment. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Rate, the Trustee may assume without inquiry
that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect. 
  

 35 

 Section 4.09 Notice of Certain Transactions. In the event that there is a dissolution or
liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the proposed effective date. The Company shall mail such notice at least 10 days before such proposed effective date. Failure to mail such
notice or any defect therein shall not affect the validity of any transaction referred to in this Section 4.09. 
 Section 4.10
Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. If any of following events occur (each, a “Business Combination”): 
 (1) any recapitalization, reclassification or change of the Common Stock, other than changes resulting from a subdivision or a combination, 
 (2) a consolidation, merger or combination involving the Company, 
 (3) a sale, conveyance or lease to another corporation of all or substantially all of the property and assets of the Company, other than one or more of the Company’s subsidiaries, or 
 (4) any statutory share exchange, 
 in each case as a
result of which holders of Common Stock are entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for Common Stock, the Company or the successor or purchasing
corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so
comply) providing that the Holders of the Securities then outstanding will be entitled thereafter to convert such Securities into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination
thereof) which they would have owned or been entitled to receive upon such Business Combination had such Securities been converted into Common Stock immediately prior to such Business Combination. In the event holders of Common Stock have the
opportunity to elect the form of consideration to be received in such Business Combination, the Securities will be convertible into the weighted average of the kind and amount of consideration received by the holders of the Common Stock that
affirmatively make such an election. The Company may not become a party to any such transaction unless its terms are consistent with this Section 4.10. Such supplemental indenture shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article 4. If, in the case of any such Business Combination, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes
shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such Business Combination, then such supplemental indenture shall also be executed by such other corporation
and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions
providing for the repurchase rights set forth in Article 3 hereof. Notwithstanding anything contained in this Section, and for the avoidance of doubt, this Section shall not affect the right of a Holder to convert its Securities into
shares of Common Stock prior to the effective date of the Business Combination. 
  

 36 

 Section 4.11 Trustee’s Disclaimer. 
 (a) The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment
should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers Certificate and/or an Opinion of Counsel, including the Officers’ Certificate with
respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.08. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee
shall not be responsible for the Company’s failure to comply with any provisions of this Article 4. 
 (b) The Trustee shall not be
under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.10, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in
relying upon, the Officers’ Certificate and Opinion of Counsel, with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 12.04. 
 Section 4.12 Voluntary Increase. The Company from time to time may increase the Conversion Rate, to the extent permitted by law, by any
amount for any period of time if the period is at least 20 days, its Board of Directors has made a determination that this increase would be in the Company’s best interests, and the Company provides 15 days prior written notice to any increase
in the Conversion Rate to the Trustee and Holders. The Company may also make such an increase to the Conversion Rate as the Board of Directors determines would avoid or diminish U.S. federal income tax to holders of shares of Common Stock in
connection with a dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for U.S. federal income tax purposes. 
 ARTICLE 5 
 GUARANTEE 
 Section 5.01 Guarantee. 
 The
Guarantor, in accordance with this Article 5, hereby absolutely, fully, unconditionally and irrevocably guarantees to the Trustee and the Holders, as if the Guarantor were the principal debtor, the punctual payment and performance when due of all
Indenture Obligations (which for purposes of this Guarantee shall also be deemed to include all commissions, fees, charges, costs and other expenses (including reasonable legal fees and disbursements of one counsel) arising out of or incurred by the
Trustee or the Holders in connection with the enforcement of this Guarantee). 
 Section 5.02 Continuing Guarantee; No Right of
Set-Off; Independent Obligation. 
 (a) This Guarantee shall be a continuing guarantee of the payment and performance of all Indenture
Obligations and shall remain in full force and effect until the payment in full of all of the Indenture Obligations and shall apply to any ultimate balance due or remaining unpaid to the Trustee or the Holders in respect of the Indenture
Obligations; and this Guarantee shall not be considered as wholly or partially satisfied by the payment or liquidation at any time or from time to time of any sum of money for the time being due or remaining unpaid to the Trustee or 

  

 37 

 
the Holders. Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts which constitute part of the
Indenture Obligations and would be owed by the Company under this Indenture and the Securities but for the fact that they are unenforceable, reduced, limited, impaired, suspended or not allowable due to the existence of a bankruptcy, reorganization
or similar proceeding involving the Company. 
 (b) The Guarantor hereby guarantees that the Indenture Obligations will be paid to the
Trustee without set-off or counterclaim or other reduction whatsoever (whether for taxes, withholding or otherwise) in lawful currency of the United States of America. 
 (c) The Guarantor guarantees that the Indenture Obligations shall be paid strictly in accordance with their terms regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any
of such terms or the rights of the Holders of the Securities. 
 (d) The Guarantor’s liability to pay or perform or cause the
performance of the Indenture Obligations under this Guarantee shall arise forthwith after demand for payment or performance by the Trustee has been given to the Guarantor in the manner prescribed in Section 12.02 hereof.

time hereafter made by the Company to the Guarantor.

collectibility and is in no way conditioned or contingent upon any attempt to collect from or enforce performance or compliance by the Company or upon any event or condition whatsoever. 
 (g) The obligations of the Guarantor set forth herein constitute the full recourse obligations of the Guarantor enforceable against it to the full extent
of all its assets and properties.

the Guarantor hereunder; 
 5. the abstention from taking security from the Company, the Guarantor or any other Person or from
perfecting, continuing to keep perfected or taking advantage of any security;

 7. Trustee’s or the Holders’ acceptance of compositions from
the Company or the Guarantor; 
 8. the application by the Holders or the Trustee of all monies at any time and from time to
time received from the Company, the Guarantor or any other Person on account of any indebtedness and liabilities owing by the Company or any Guarantor to the Trustee or the Holders, in such manner as the Trustee or the Holders deems best and the
changing of such application in whole or in part and at any time or from time to time; 
 9. the release or discharge of the
Company or the Guarantor of the Securities or of any Person liable directly as surety or otherwise by operation of law or otherwise for the Securities, other than an express release in writing given by the Trustee, on behalf of the Holders, of the

Guarantor; 
 15. any failure, omission or delay on the part of the Company to conform or comply with any term of this
Indenture;

any discharge, termination, cancellation, distribution, irregularity, invalidity or unenforceability in whole or in part of this Indenture; 
 17. any other circumstance (including any statute of limitations) that might otherwise constitute a defense available to, or discharge of, the Company or the Guarantor; or 
 18. any modification, compromise, settlement or release by the Trustee, or by operation of law or otherwise, of the Indenture Obligations
or the liability of the Company or any other obligor under the Securities, in whole or in part, and any refusal of payment by the Trustee, in whole or in part, from any other obligor or other guarantor in connection with any of the Indenture
Obligations, whether or not with notice to, or further assent by, or any reservation of rights against, the Guarantor. 
 Section 5.04
Right to Demand Full Performance. 
 In the event of any demand for payment or performance by the Trustee from the Guarantor hereunder,
the Trustee or the Holders shall have the right to demand its full claim and to receive all dividends or other payments in respect thereof until the Indenture Obligations have been paid in full, and the Guarantor shall continue liable hereunder for
any balance which may be owing to the Trustee or the Holders by the Company under this Indenture and the Securities. The retention by the Trustee or the Holders of any security, prior to the realization by the Trustee or the Holders of its rights to
such security upon foreclosure thereon, shall not, as between the Trustee and the Guarantor, be considered as a purchase of such security, or as payment, satisfaction or reduction of the Indenture Obligations due to the Trustee or the Holders by the
Company or any part thereof. The Guarantor, promptly after demand, will reimburse the Trustee and the Holders for all costs and expenses of collecting such amount under, or enforcing this Guarantee, including, without limitation, the reasonable fees
and expenses of one counsel.

 Section 5.05 Waivers. 
 (a) The Guarantor hereby expressly waives (to the extent permitted by law) notice of the acceptance of this Guarantee and notice of the existence,
renewal, extension or the non-performance, non-payment, or non-observance on the part of the Company of any of the terms, covenants, conditions and provisions of this Indenture or the Securities or any other notice whatsoever to or upon the Company
or the Guarantor with respect to the Indenture Obligations, whether by statute, rule of law or otherwise. The Guarantor hereby acknowledges communication to it of the terms of this Indenture and the Securities and all of the provisions therein
contained and consents to and approves the same. The Guarantor hereby expressly waives (to the extent permitted by law) diligence, presentment, protest and demand for payment with respect to (i) any notice of sale, transfer or other disposition
of any right, title to or interest in the Securities by the Holders or in this Indenture, (ii) any release of the Guarantor from its obligations hereunder resulting from any loss by it of its rights of subrogation hereunder and (iii) any
other circumstances whatsoever that might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety or that might otherwise limit recourse against such Guarantor. 
 (b) Without prejudice to any of the rights or recourses which the Trustee or the Holders may have against the Company, the Guarantor hereby expressly
waives (to the extent permitted by law) any right to require the Trustee or the Holders to: 
 (1) enforce, assert, exercise,
initiate or exhaust any rights, remedies or recourse against the Company or any other Person under this Indenture or otherwise; 
 (2) value, realize upon, or dispose of any security of the Company or any other Person held by the Trustee or the Holders; 
 (3) initiate or exhaust any other remedy which the Trustee or the Holders may have in law or equity; or 
 (4)
mitigate the damages resulting from any default under this Indenture; 
 before requiring or becoming entitled to demand payment under this Guarantee.

 Section 5.06 The Guarantor Remain Obligated in Event the Company Is No Longer Obligated to Discharge Indenture Obligations.

 It is the express intention of the Trustee and the Guarantor that if for any reason the Company has no legal existence, is or becomes
under no legal obligation to discharge the Indenture Obligations owing to the Trustee or the Holders by the Company or if any of the Indenture Obligations owing by the Company to the Trustee or the Holders becomes irrecoverable from the Company by
operation of law or for any reason whatsoever, this Guarantee and the covenants, agreements and obligations of the Guarantors contained in this Article 5 shall nevertheless be binding upon the Guarantor, as principal debtor, until such time as all
such Indenture Obligations have been paid in full to the Trustee and all Indenture Obligations owing to the Trustee or the Holders by the Company have been discharged. 
  

 41 

 Section 5.07 Limitation on Guarantor Liability. 
 The Guarantor is a Subsidiary of the Company and, by its acceptance hereof, each Holder hereby confirms that it is the intention of all such parties that
the Guarantee by such 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. To effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the obligations of such Guarantor under its Guarantee shall be limited to the maximum amount which, after giving effect to all other
contingent and fixed liabilities of the Guarantor, will result in the obligations of such Guarantor under its Guarantee not constituting such fraudulent transfer or conveyance. 
 Section 5.08 Guarantee is in Addition to Other Security. 
 This Guarantee shall be in addition to and not in substitution for any other guarantees which the Trustee may now or hereafter hold in respect of the Indenture Obligations owing to the Trustee or the Holders by the
Company and (except as may be required by law) the Trustee shall be under no obligation to marshal in favor of the Guarantor any other guarantees or any moneys or other assets which the Trustee may be entitled to receive or upon which the Trustee or
the Holders may have a claim. 
 Section 5.09 No Bar to Further Actions. 
 Except as provided by law, no action or proceeding brought or instituted under this Article 5 and this Guarantee and no recovery or judgment in pursuance
thereof shall be a bar or defense to any further action or proceeding which may be brought under this Article 5 and this Guarantee by reason of any further default or defaults under this Article 5 and this Guarantee or in the payment of any of the
Indenture Obligations owing by the Company. 
 Section 5.10 Failure to Exercise Rights Shall Not Operate as a Waiver; No Suspension
of Remedies. 
 (a) No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, power,
privilege or remedy under this Article 5 and this Guarantee shall operate as a waiver thereof, nor shall any single or partial exercise of any rights, power, privilege or remedy preclude any other or further exercise thereof, or the exercise of any
other rights, powers, privileges or remedies. The rights and remedies herein provided for are cumulative and not exclusive of any rights or remedies provided in law or equity. 
 (b) Nothing contained in this Article 5 shall limit the right of the Trustee or the Holders to take any action to accelerate the maturity of the
Securities pursuant to Article 8 or to pursue any rights or remedies hereunder or under applicable law. 
  

 42 

 Section 5.11 Trustee’s Duties; Notice to Trustee. 
 (a) Any provision in this Article 5 or elsewhere in this Indenture allowing the Trustee to request any information or to take any action authorized by, or
on behalf of the Guarantor, shall be permissive and shall not be obligatory on the Trustee except as the Holders may direct in accordance with the provisions of this Indenture or where the failure of the Trustee to request any such information or to
take any such action arises from the Trustee’s negligence, bad faith or willful misconduct. 
 (b) The Trustee shall not be required to
inquire into the existence, powers or capacities of the Company, the Guarantor or the officers, directors or agents acting or purporting to act on their respective behalf. 
 Section 5.12 Successors and Assigns. 
 All terms, agreements and conditions of this Article 5 shall extend to and be binding upon the Guarantor and its successors and permitted assigns and shall inure to the benefit of and may be enforced by the Trustee and its successors and
assigns; provided, however, that the Guarantor may not assign any of its rights or obligations hereunder other than in accordance with Article 7 hereof. 
 Section 5.13 Release of Guarantee. 
 Concurrently with the payment in full of all of the
Indenture Obligations, the Guarantor shall be released from and relieved of its obligations under this Article 5. Upon the delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that the
transaction giving rise to the release of this Guarantee was made by the Company in accordance with the provisions of this Indenture and the Securities, the Trustee shall execute any documents reasonably required in order to evidence the release of
the Guarantor from its obligations under this Guarantee. If any of the Indenture Obligations are revived and reinstated after the termination of this Guarantee, then all of the obligations of the Guarantor under this Guarantee shall be revived and
reinstated as if this Guarantee had not been terminated until such time as the Indenture Obligations are paid in full, and the Guarantor shall enter into an amendment to this Guarantee, reasonably satisfactory to the Trustee, evidencing such revival
and reinstatement. 
 Section 5.14 Execution of Guarantee. 
 (a) To evidence the Guarantee, the Guarantor hereby agrees to execute the guarantee substantially in the form set forth in Exhibit B hereto, to be
endorsed on each Security authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of the Guarantor by one of its Chairman of the Board, its President, its Chief Executive Officer, its President, its Chief
Operating Officer, any Executive Vice President or Vice President, its Treasurer, its Assistant Treasurer, its Secretary or its Assistant Secretary. The signature of any of these officers on the Securities may be manual or facsimile.

Trustee authenticates a Security on which this Guarantee is endorsed, such Guarantee shall be valid nevertheless. 
 ARTICLE 6

 COVENANTS 
 Section 6.01 Payment of Securities. 
 (a) The Company shall promptly make all payments in respect of the Securities on
the dates and in the manner provided in the Securities and this Indenture. A payment of principal or interest or Additional Interest, if any, shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by
12:00 p.m. (noon), New York City time, on that date money, deposited by or on behalf of the Company sufficient to make the payment. Subject to Section 4.02, accrued and unpaid 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. Principal, Fundamental Change Repurchase Price, interest and Additional Interest, if any, in each case if payable, shall be considered paid on the applicable date due if on such date (or, in the case of Fundamental Change Repurchase
Price, on the Business Day following the applicable Fundamental Change Repurchase Date) the Trustee or the Paying Agent holds, in accordance with this Indenture, money sufficient to pay all such amounts then due. The Company shall, to the fullest
extent permitted by law, pay interest in immediately available funds on overdue principal amount and interest at the annual rate borne by the Securities compounded semiannually, 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. Payment-in-Kind Interest shall be considered paid on the date due if the Trustee is
directed on or prior to such date to issue Payment-in-Kind Securities or increase the principal amount of the applicable Securities, in each case in an amount equal to the amount of the applicable Payment-in-Kind Interest. 
 (b) Payment of the principal of and interest, if any, on the Securities shall be made at the office or agency of the Company maintained for that purpose
(which shall initially be at the address set forth in Section 2.03(c)) in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the
option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided further that a Holder with an aggregate principal amount in excess of $2,000,000
will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire transfer instructions
received by the Trustee will remain in effect until revoked by the Holder. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of
immediately available funds to the account of the Depositary or its nominee.

 Section 6.02 SEC and Other Reports. 
 The Company shall file in a timely fashion all reports and other information and documents which it is required to file with the SEC pursuant to
Section 13 or 15(d) of the Exchange Act (including its Annual Report on Form 10-K and its Quarterly Reports on Form 10-Q), and within 15 days after it files them with the SEC, the Company shall file copies of all such reports,
information and other documents with the Trustee; provided that any such reports, information and documents filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system shall be deemed to be filed with the
Trustee. In the event that the Company is no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall continue to provide the Trustee, the Holders and, upon request, beneficial owners of
Securities with reports containing substantially the same information as would be required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports will be provided at the
times the Company would have been required to provide reports had it continued to be subject to such reporting requirements. In addition, in such event the Company will (i) hold a quarterly conference call to discuss the quarterly and annual
information contained in the reports no later than five business days from the time the Company furnishes such information to the Trustee; (ii) no fewer than three business days prior to the date of the conference call required to be held in
accordance with clause (i) above, issue a press release to the appropriate wire services for broad dissemination in the United States and Canada announcing the time and date of such conference call and directing the beneficial owners of the
Securities, prospective investors and securities analysts to contact the investor relations office of the Company to obtain the reports and information and how to access such conference call; and (iii) either (x) maintain an unrestricted
public website on which the reports and conference call access details are posted; (y) maintain a non-public website to which beneficial owners of the Securities, prospective investors and securities analysts are given access and to which the
reports and conference call access details are posted or (z) distribute via e-mail such reports and conference call details to beneficial owners of the Securities, prospective investors and securities analysts who request to receive such
distributions. The Company also shall comply with the provisions of TIA Section 314(a). 
 (a) Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 Section 6.03 Compliance Certificates. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending December 31,
2008), an Officers’ Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and covenants on its part contained in this Indenture and stating whether or not the signer knows of any Default or Event of
Default. If such signer knows of such a Default or Event of Default, the Officers’ Certificate shall describe the Default or Event of Default and the efforts to remedy the same. For the purposes of this Section 6.03, compliance shall be
determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. 
  

 45 

 Section 6.04 Further Instruments and Acts. Upon request of the Trustee, the Company and the
Guarantor will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
 Section 6.05 Maintenance of Corporate Existence. Subject to Article 7, each of the Company and the Guarantor will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 6.06 Rule 144A
Information Requirement. So long as any Securities remain outstanding, the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, upon the request of any
Holder or beneficial holder of the Securities make available to such Holder or beneficial holder of Securities or any Common Stock issued upon conversion thereof which continue to be Restricted Securities in connection with any sale thereof and any
prospective purchaser of Securities or such Common Stock designated by such Holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act and it will take such further action as any Holder or
beneficial holder of such Securities or such Common Stock may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or Common Stock without registration under the
Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Whether a person is a beneficial holder shall be determined by the Company. 
 Section 6.07 Stay, Extension and Usury Laws. The Company and the Guarantor covenant (to the extent that they may lawfully do so) that they
shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company or the Guarantor from paying all or any
portion of the principal of or accrued but unpaid interest or Additional Interest, if any, on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of
this Indenture, and the Company and the Guarantor (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenant that they will not, by resort to any such law, hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
 Section 6.08 Payment of Additional Interest. If Additional Interest is payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an Officers’
Certificate to that effect stating (i) the amount of such Additional Interest that is payable, (ii) the reason why such Additional Interest is payable and (iii) the date on which such Additional Interest is payable. Unless and until a
Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to such Additional
Interest, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. The Trustee may conclusively rely on the correctness of the Additional Interest calculations provided by the Company without
investigation. 
  

 46 

 Section 6.09 Maintenance of Office or Agency. The Company will maintain an office or agency
of the Trustee, Registrar and Paying Agent where securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or purchase and where notices and demands to or upon the Company in respect of
the Securities and this Indenture may be served. The Corporate Trust Office shall initially be one such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any
change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.02. 
 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. 
 Section 6.10 Voting Rights. Without the consent of the Holders of not less than a majority in aggregate principal amount of the Securities then outstanding, voting as a class, (i) the Company will
not, and will not permit any of its Subsidiaries to, directly or indirectly, incur, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness if
after the incurrence of such Indebtedness the Company’s total Indebtedness, on a consolidated basis, would exceed $7,500, 000,000 and (ii) the Company will not pay any dividends on its Common Stock (other than a dividend paid solely in
shares of Common Stock).

 (b) Notwithstanding Section 8.01(a), no
Event of Default under clauses (4) or (5) of Section 8.01(a) shall occur until the Trustee notifies the Company in writing upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then
outstanding, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the Default
within the time specified in clause (4) or (5) of Section 8.01(a), as applicable, after receipt of such notice. A notice given pursuant to this Section 8.01 shall be given by registered or certified mail, must specify the
Default, demand that it be remedied and state that the notice is a Notice of Default. When any Default under this Section 8.01 is cured, it ceases. 
 (c) The Company will deliver to the Trustee, within five Business Days after becoming aware of the occurrence of a Default or Event of Default, written notice thereof. 
 The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Responsible Officer with
responsibility for this Indenture at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder or unless a Responsible Officer with responsibility for this Indenture acquires actual knowledge of
such Event of Default in the course of performing other duties pursuant to this Indenture. 
 Section 8.02 Acceleration. If an
Event of Default (other than an Event of Default specified in clause (6) or (7) of Section 8.01(a)) occurs and is continuing with respect to the Company or the Guarantor, the Trustee may, by notice to the Company, and shall upon the
written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the
Trustee, declare the principal amount and accrued and unpaid interest, if any, and accrued and unpaid Additional Interest, if any, through the date of declaration on all the Securities to be immediately due and payable. Upon such a declaration, such
principal amount and such accrued and unpaid interest, if any, and such accrued and unpaid Additional Interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 8.01(a)(6) or (7) occurs in respect
of the Company or the Guarantor or any of the Guarantor’s Subsidiaries and is continuing, the principal amount and accrued but unpaid interest, if any, and accrued and unpaid Additional Interest, if any, on all the 

  

 50 

 
Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Securities. The
Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal
of the Securities which have become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities) on
overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent
jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 9.07 have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 
 Section 8.03 Other Remedies. 
 (a) If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect payment of the principal amount and accrued and unpaid interest,
if any, and accrued and unpaid Additional Interest, if any, on the Securities or to enforce the performance of any provision of the Securities, the Guarantee or this Indenture. 
 (b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder 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. No remedy is exclusive of any other
remedy. All available remedies are cumulative to the extent permitted by applicable law. 
 Section 8.04 Waiver of Defaults and
Events of Default. Subject to Sections 8.02, 8.07 and 11.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its
consequences, except an uncured Default or Event of Default in the payment of the principal of, premium, if any, or any accrued but unpaid interest on any Security, an uncured failure by the Company to convert any Securities into Common Stock or any
Default or Event of Default in respect of any provision of this Indenture, the Guarantee or the Securities which, under Section 11.02, cannot be modified or amended without the consent of the Holder of each Security affected. When a Default or
Event of Default is waived, it is cured and ceases to exist. 
 Section 8.05 Control by Majority. The Holders of a majority in
aggregate principal amount of the Securities then outstanding may direct the time method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is
offered security or indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
  

 51 

 Section 8.06 Limitations on Suits. 
 (a) A Holder may not pursue any remedy with respect to this Indenture, the Guarantee or the Securities (except actions for payment of overdue principal,
premium, if any, or interest or for the conversion of the Securities pursuant to Article 4) unless: 
 (1) the Holder gives to the
Trustee written notice of a continuing Event of Default; 
 (2) the Holders of at least 25% in aggregate principal amount of the then
outstanding Securities make a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to the Trustee
security or indemnity acceptable to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the request
within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) no direction inconsistent with such written
request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding. 
 (b) No Holder of a Security shall have any right under any provision of this Indenture, the Guarantee or the Securities to affect, disturb, or prejudice the rights of another Holder of a Security or to obtain a
preference or priority over another Holder of a Security. 
 Section 8.07 Rights of Holders to Receive Payment and to Convert.
Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of the principal amount, Fundamental Change Repurchase Price and interest, if any, or Additional Interest, if any, in respect of the
Securities held by such Holder, on or after the respective due dates expressed in the Securities and this Indenture, (whether upon repurchase or otherwise), and to convert such Security in accordance with Article 4, and to bring suit for the
enforcement of any such payment on or after such respective due dates or for the right to convert in accordance with Article 4, is, subject to compliance with the provisions of Section 8.06, absolute and unconditional and shall not be
impaired or affected without the consent of the Holder. 
 Section 8.08 Collection Suit by Trustee. If an Event of Default
described in clause (1) or (2) of Section 8.01(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole
amount owing with respect to the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel. 
 Section 8.09 Trustee may File Proofs of Claim. The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in

  

 52 

 
any judicial proceedings relative to the Company (or any other obligor on the Securities or the Guarantee), its creditors or its property and shall be
entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any Receiver in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.07, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation
or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt 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.

the Trustee collects any money pursuant to this Article 8, it shall pay out the money in the following order: 
 (1) First, to the
Trustee for amounts due under Section 9.07; 
 (2) Second, to Holders for amounts due and unpaid on the Securities for the principal
amount, interest, and Additional Interest, as applicable, ratably, without preference or priority of any kind, according to such respective amounts due and payable on the Holders’ Securities; and 
 (3) Third, the balance, if any, to the Company. 
 (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 8.10. 
 Section 8.11 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 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 (whether incurred before trial,
at trial, on appeal or in any bankruptcy or arbitration or other administrative proceeding), 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 8.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 8.07, or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding. This Section 8.11 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.

 ARTICLE 9 
 TRUSTEE 
 Section 9.01 Obligations of Trustee. 
 (a) If an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge has occurred and is continuing, the Trustee may (and
shall upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding and being furnished with indemnity acceptable to it) exercise such of the rights and powers vested in it by this
Indenture. If an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge has occurred and is continuing, the Trustee shall 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 his or her own affairs. 
 (b) Except during the continuance of an Event of Default of which a
Responsible Officer of the Trustee shall have actual knowledge, the Trustee need perform only those duties as are specifically set forth in this Indenture and no others. 
 This Section 9.01(b) shall be in lieu of Section 315(a) of the TIA and such Section 315(a) is hereby expressly excluded from this Indenture, as permitted by the TIA. 
 (c) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee, however, shall examine any certificates and opinions which by any provision hereof are specifically required
to be delivered to the Trustee to determine whether or not they conform on their face to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein 
 (d) The Trustee may not be relieved from liability for its own gross negligent action, its own gross negligent failure to act, or its own willful
misconduct, except that: 
 (1) this paragraph does not limit the effect of Section 9.01(b); 
 (2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was
grossly negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with this Indenture or a direction received by it pursuant to Section 8.05.

 (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties

hereunder or in the exercise of any of its rights or powers unless the Trustee shall have received adequate security or indemnity in its opinion against
potential costs and liabilities incurred by it relating thereto.

Trustee is subject to subsections (a), (b), (c), (d) and (e) of this Section 9.01.

interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 Section 9.02 Rights of Trustee. 
 (a) Subject to Section 9.01: 
 (1) The Trustee may rely conclusively and shall be protected in acting or refraining from
acting upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 
 (2) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel, which shall conform to
Section 12.04(b). The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. 
 (3) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys or
custodians, and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent, attorney or custodian appointed by the Trustee with due care. 
 (4) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or
powers. 
 (5) The Trustee may consult with counsel of its selection, and the advice or opinion of such counsel as to matters of law shall

any litigation hereunder or in relation hereto at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs,
expenses and liabilities which might be incurred by it in compliance with such request or direction.

paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if
the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company, and shall incur no
liability or additional liability of any kind by reason of such inquiry or investigation. 
 (8) The Trustee shall not be deemed to have
notice or knowledge of any Default or Event of Default, or Fundamental Change unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee
at the Corporate Trust Office, and such notice references the Securities and this Indenture. In the absence of receipt of such notice or actual knowledge, the Trustee may conclusively assume that there is no Default, Event of Default, or Fundamental
Change. 
 (9) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right
to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including, without limitation as Paying Agent, Registrar and Conversion Agent, and to each agent, custodian and other Person employed
to act hereunder. 
 (10) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of
any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 Section 9.03 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 an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 9.10 and 9.11. 
 Section 9.04 Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture, the Guarantee
or the Securities. It shall not be accountable for the Company’s use of the proceeds from the Securities and it shall not be responsible for any statement in the Securities other than its certificate of authentication. 
 Section 9.05 Notice of Default or Events of Default. If a Default or an Event of Default occurs and is continuing and if it is known to a
Responsible Officer of the Trustee, the Trustee shall mail to each Holder of a Security notice of all uncured Defaults or Events of Default known to it within 90 days after it occurs or, if later, within 15 days after it becomes known to the
Trustee. However, the Trustee may withhold the notice if and for so long as a committee of its Responsible Officers in good faith determines that withholding notice is in the interests of Holders of Securities, except in the case of a Default or an
Event of Default in payment of the principal of, or premium, if any, or interest on any Security when due or in the payment of any purchase obligation, or the Company’s failure to convert Securities when obligated to convert them. This
Section 9.05 is in lieu of section 315(b) of the TIA and such provision is expressly excluded from this Indenture as permitted by the TIA. 
  

 56 

 Section 9.06 Reports by Trustee to Holders. 
 (a) If a report is required by TIA Section 313, within 60 days after each March 15, beginning with the March 15 following the date of this
Indenture, the Trustee shall mail to each Holder of Securities a brief report dated as of such March 15 that complies with TIA Section 313(a). If required by TIA Section 313, the Trustee also shall comply with TIA Sections 313(b)(2),
(c) and (d).

extent required by the TIA, filed with the SEC, and each stock exchange, if any, on which the Securities are listed. The Company shall notify the Trustee whenever the Securities become listed on any stock exchange or listed or admitted to trading on
any quotation system and any changes in the stock exchanges or quotation systems on which the Securities are listed or admitted to trading and of any delisting thereof. 
 Section 9.07 Compensation and Indemnity. 
 (a) The Company shall pay to the Trustee from time to

counsel. 
 (b) The Company shall indemnify and hold harmless the Trustee or any predecessor Trustee (which for purposes of this
Section 9.07 shall include its officers, directors, employees and agents) for, and hold it harmless against, any and all loss, liability, claim, damage or expense including taxes (other than franchise taxes and taxes based upon, measured by or
determined by the income of the Trustee), incurred by it in connection with the acceptance or administration of its duties under this Indenture or any action or failure to act as authorized or within the discretion or rights or powers conferred upon
the Trustee hereunder including the reasonable costs and expenses of the Trustee and its counsel in defending (including reasonable legal fees and expenses whether incurred before trial, at trial, on appeal or in any bankruptcy or arbitration or
other administrative proceeding) itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee
for which it may seek indemnity. The Company need not pay for any settlement effected without its prior written consent, which shall not be unreasonably withheld.

 57 

 (d) To secure the Company’s payment obligations in this Section 9.07, the Trustee shall have a
senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee. The obligations of the Company under this Section 9.07 shall survive the satisfaction and discharge of this Indenture or
the resignation or removal of the Trustee. 
 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in
clause (6) or (7) of Section 8.01(a) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The provisions of this Section shall survive the
termination of this Indenture. 
 Section 9.08 Replacement of Trustee. 
 (a) The Trustee may resign by so notifying the Company. The Holders of a majority in aggregate principal amount of the Securities then outstanding may
remove the Trustee by so notifying the Trustee and the Company and may, with the Company’s written consent, appoint a successor Trustee. The Company may remove the Trustee at any time, so long as no Default or Event of Default has occurred and

the expense of the Company. 
 (d) If the Trustee fails to comply with Section 9.10, any Holder may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

liabilities that the retiring Trustee may have incurred while acting as Trustee) hereunder, 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. A successor Trustee shall mail notice of its succession to each Holder. 
 (f) A retiring Trustee shall not be
liable for the acts or omissions of any successor Trustee after its succession.

obligations under Section 9.07 shall continue for the benefit of the retiring Trustee. 
 Section 9.09 Successor Trustee by
Merger, etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business (including the administration of this Indenture) to, another corporation, the resulting, surviving or

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.

Company cause to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any unclaimed balance of such money
then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 
  

 60 

 Section 10.04 Reinstatement. If the Trustee or any Paying Agent is unable to apply any money
in accordance with Section 10.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s
obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01 until such time as the Trustee or such Paying Agent is permitted to apply all such money in
accordance with Section 10.02; provided, however, that if the Company has made any payment of the principal of or interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the

 62 

 (c) After an amendment, supplement or waiver under this Section 11.02 becomes effective, the Company
shall promptly mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity
of any such amendment, supplement or waiver.

supplement of this Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or supplement.

such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 
 (b) After an amendment, supplement or waiver becomes effective, it shall bind every Holder of a Security. 
 Section 11.05 Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may
require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. 
 Section 11.06 Trustee to Sign Amendments, etc. The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 11 if the amendment or supplemental indenture does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with and,
subject to Section 9.01, shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not
sign an amendment or supplemental indenture until the Board of Directors approves it. 
 Section 11.07 Effect of Supplemental
Indentures. Upon the execution of any supplemental indenture under this Article 11, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every

 [FORM OF REVERSE SIDE OF SECURITY] 
 ABITIBIBOWATER INC. 
 8% CONVERTIBLE SENIOR NOTES DUE 2013 
  

	 	1.	INTEREST 

 AbitibiBowater Inc., a Delaware corporation (the
“Company”, which term shall include any successor corporation under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rates set forth below. Interest on the Securities shall be
payable entirely in cash (“Cash Interest”); provided that if the Board of Directors of the Company determines in good faith that the Company will not have sufficient cash resources on hand to pay Cash Interest on the Securities at the time
of the relevant Interest Payment Date (as defined below), the Company may pay interest on the Securities entirely by increasing the principal amount of this Security or issuing new Securities (“Payment-in-Kind Interest” or “PIK
Interest”) as set forth below. Cash Interest will accrue at a rate of 8% per annum. Payment-in-Kind Interest will accrue at a rate of 10% per annum. If the Company elects to pay Payment-in-Kind Interest, the Company shall
(i) increase the principal amount of this Security in an aggregate principal amount equal to the amount of Payment-in-Kind Interest for the applicable interest period (rounded to the nearest whole dollar) or (ii) issue new Securities
(“Payment-in-Kind Securities” or “PIK Securities”) in an aggregate principal amount equal to the amount of Payment-in-Kind Interest for the applicable interest period (rounded up to the nearest whole dollar) to the Holder of this
Security on the relevant record date. This Security will bear interest on the increased principal amount thereof from and after the applicable Interest Payment Date on which a payment of Payment-in-Kind Interest is made. Interest shall accrue on
Payment-in-Kind Securities issued from and including the date such Securities are issued. All Securities issued under the Indenture, including any Payment-in-Kind Securities, shall be issued on the same terms, shall constitute part of the same
series and shall vote together as one series on all matters with respect to the Securities. The Company shall elect the form of interest payment with respect to each interest period by delivering a notice to the Trustee at least ten Business Days
prior to the applicable Interest Payment Date; provided, however, that in respect of the first full interest period during which the initial purchasers of the Securities own less than 90% of the Securities, and in respect of all subsequent interest
periods, such notice must be delivered to the Trustee at least ten Business Days prior to the beginning of such interest period. The Trustee shall promptly deliver a corresponding notice to the Holders of this Security. In the absence of such an
election or proper notification of such election to the Trustee, interest will be payable according to the election for the previous interest period. The Company will make any payments of PIK Interest in respect of the Securities represented by
Global Securities by increasing the principal amount of such Global Securities. The Company will make any payments of PIK Interest in respect of Securities represented by Certificated Securities by issuing PIK Securities in the form of Certificated
Securities and delivering them to Holders. 
 The Company will pay interest semi-annually in arrears on October 15 and April 15 of
each year (each, an “Interest Payment Date”), beginning on October 15, 2008. Each payment of interest will include interest accrued for the period commencing on and including the immediately preceding Interest Payment Date, provided
that the first interest payment on October 15, 2008, will include interest from April 1, 2008 through the day before the relevant 

  

 A-4 

 
Interest Payment Date (or purchase date, as the case may be). Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Any
payment required to be made on a day that is not a Business Day shall be made on the next succeeding Business Day. Any reference herein to interest accrued or payable as of any date shall include any Additional Interest accrued or payable on such
date as provided in the Registration Rights Agreement. 
 No sinking fund is provided for the Securities. 
  

	 	2.	METHOD OF PAYMENT 

 The Company shall pay interest on this
Security (except defaulted interest) to the person who is the Holder of this Security at the close of business on April 1 or October 1, as the case may be, (each, a “Regular Record Date”) next preceding the related Interest
Payment Date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and
private debts. The Company may pay principal and interest in respect of any Certificated Security by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by
wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the Payment Date. The Company may mail an interest check to the
Holder’s registered address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of
the Depositary or its nominee. 
 Any wire transfer instructions received by the Trustee will remain in effect until revoked by the Holder.

  

	 	3.	PAYING AGENT, REGISTRAR AND CONVERSION AGENT 

 Initially,
The Bank of New York Trust Company, N.A. (the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any
Paying Agent, Registrar or Conversion Agent without notice to the Holder. The Company or any of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent or Registrar. 
  

	 	4.	INDENTURE, LIMITATIONS 

 This Security is one of a duly
authorized issue of Securities of the Company designated as its 8% Convertible Senior Notes Due 2013 (the “Securities”), issued under an Indenture dated as of April 1, 2008 (together with any supplemental indentures thereto, the
“Indenture”), between the Company, the Guarantor and the Trustee. The terms of this Security include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this security is referred to the Indenture and said Act for a statement of them. Capitalized terms not defined herein have the meaning
ascribed to such terms in the Indenture. 
  

 A-5 

 The Securities are unsecured, senior obligations of the Company limited to $350,000,000 aggregate
principal amount plus any amount in respect of PIK Interest thereon. 
  

	 	5.	PURCHASE OF SECURITIES AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE 

 If a Fundamental Change occurs prior to the Final Maturity Date, at the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase for cash, subject
to certain exceptions described in the Indenture all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000, or if Payment-in-Kind Interest is paid, a minimum of $1.00 or an
integral multiple of $1.00) of the Securities held by such Holder on a date specified by the Company that is not less than 30 nor more than 45 days after the date of the Fundamental Change Company Notice, at a purchase price equal to 110% of the
principal amount thereof together with accrued and unpaid interest, if any, and accrued and unpaid Additional Interest, if any, to, but excluding, the Fundamental Change Repurchase Date. The Holder shall have the right to withdraw any Fundamental
Change Repurchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000, or if Payment-in-Kind Interest is paid, $1.00 and an integral multiple of $1.00) at any time prior to the close of business on the Business
Day next preceding the Fundamental Change Repurchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 
  

	 	6.	CONVERSION 

 Subject to and upon compliance with the
provisions of the Indenture, a Holder may surrender for conversion any Security that is $1,000 principal amount or integral multiples thereof. 
  

	 	7.	RESERVED 

  

	 	8.	DENOMINATIONS, TRANSFER, EXCHANGE 

 The Securities are in
registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount, or if Payment-in-Kind Interest is paid, a minimum of $1.00 or an integral multiple of $1.00 (in each case in aggregate
principal amount). A Holder may register the transfer of 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
or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 
  

	 	9.	PERSONS DEEMED OWNERS 

 The Holder of a Security may be
treated as the owner of it for all purposes. 
  

	 	10.	UNCLAIMED MONEY 

 If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and any Paying Agent will pay the money back to the Company at its written request, 

  

 A-6 

 
subject to applicable unclaimed property law and the provisions of the Indenture. After that, Holders entitled to money must look to the Company for payment
as general creditors unless an applicable abandoned property law designates another person. 
  

	 	11.	AMENDMENT, SUPPLEMENT AND WAIVER 

 Subject to certain
exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and an existing Default or Event of Default and its
consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without the
consent of or notice to any Holder, the Company, the Guarantor and the Trustee may amend or supplement the Indenture or the Securities as provided in the Indenture. 
  

	 	12.	SUCCESSOR ENTITY

 Notwithstanding the above, no Event of Default under clauses (4) or (5) above shall occur until
the Trustee notifies the Company in writing upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, or the Holders of at least 25% in aggregate principal amount of the Securities
then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within the time specified in clause (4) or (5), as applicable, after receipt of such
notice. 
 If an Event of Default (other than an Event of Default specified in clause (6) or (7) above) occurs and is continuing with respect to
the Company or the Guarantor the Trustee may, by notice to the Company and shall upon the written direction of the Holders of at least 25% in aggregate principal amount of the Securities then outstanding, or the Holders of at least 25% in aggregate
principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, and accrued and unpaid Additional Interest, if any, through the date of
declaration on all the Securities to be immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, and such accrued and unpaid Additional Interest, if any, shall be due and payable
immediately. If an Event of Default specified in clauses (6) or (7) occurs in respect of the Company, the Guarantor or any of the Guarantor’s Subsidiaries and is continuing, the principal amount and accrued but unpaid interest, if
any, and accrued and unpaid Additional Interest, if any, 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 Holders of Securities. The Holders of a majority in
aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which
have become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities) on overdue installments of
interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all
payments due to the Trustee and any predecessor Trustee under the Indenture have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. Holders may not enforce the Indenture or the Securities except
as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then
outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if and so long as it determines that withholding
notice is in their interests. The Company is required to file periodic certificates with the Trustee as to the Company’s compliance with the Indenture and knowledge or status of any Default. 
  

	 	14.	TRUSTEE DEALINGS WITH THE COMPANY 

 The Bank of New York
Trust Company, N.A., the initial Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the
Company or an Affiliate of the Company, as if it were not the Trustee.
