the address of the Person entitled thereto as it appears in the Note Register or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. If a payment date is not a Business Day,
payment shall be made on the next succeeding Business Day, and no additional interest shall accrue thereon. The term “Record Date” with respect to any interest payment date shall mean the January 15 or July 15 preceding
the applicable February 1 or August 1 interest payment date, respectively. 
 Any interest on any Note which is payable, but is not
punctually paid or duly provided for, on any February 1 or August 1 (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Noteholder registered as such on the relevant Record Date, and such
Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
 (1) The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at 5:00 p.m., New York City time, on a special record date for the payment of such Defaulted
Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than

provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall be not more than fifteen calendar days
and not less than ten calendar days prior to the date of the proposed payment, and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment (unless, the Trustee shall consent to an earlier date). The
Trustee shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed,
first-class postage prepaid, to each holder at his address as it appears in the Note Register, not less than ten calendar days prior to such special record date (unless, the Trustee shall consent to an earlier date). Notice of the proposed payment
of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at 5:00 p.m., New York City
time, on such special record date and shall no longer be payable pursuant to the following clause (2) of this Section 2.03. 
 (2)
The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon
such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

 Section 2.04. Execution of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile
signature of an Officer. Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent
appointed by the Trustee as provided by Section 16.11), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by
the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. 
 In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the Company, and any
Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an
officer.

Noteholder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding. 
 All Notes issued
upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or
exchange. 
 All Notes presented or surrendered for registration of transfer or for exchange, redemption, repurchase or conversion shall (if
so required by the Company or the Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, and the Notes shall be duly executed by the Noteholder thereof or his
attorney duly authorized in writing.

 (ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and
no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (1) the Depositary (x) has notified the Company that it is unwilling or unable to continue
as Depositary for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act, and a successor depositary has not been appointed by the Company within ninety calendar days, (2) an Event of Default has
occurred and is continuing or (3) the Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have all the Notes represented by Global Notes. Any Global Note exchanged pursuant to clause (A) or
(B) above shall be so exchanged in whole and not in part and any Global Note exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Company. Any Note issued in exchange for a Global
Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note. 
 (iii) Securities issued in exchange for a Global Note or any portion thereof pursuant to clause (ii) above shall be issued in
definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations
as the Depositary shall designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Note Registrar. With regard to any Global Note to be exchanged in
part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the
portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Note issuable on such exchange

to or upon the written order of the Depositary or an authorized representative thereof. 
 (iv) In the event of the occurrence of any of the events specified in clause (ii) above, the Company will promptly make available to
the Trustee a reasonable supply of certificated Notes in definitive, fully registered form, without interest coupons. 
 (v)
Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the
name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for
all purposes whatsoever. Notwithstanding the foregoing, nothing 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 Note. 
 (vi) At such time as all interests in a Global Note have been redeemed, repurchased,
converted, canceled or exchanged for Notes in certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At
any time prior to such cancellation, if any interest in a Global Note is redeemed, repurchased, converted, canceled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing
procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such
reduction. 
 (c) Every Note (and all securities issued in exchange therefor or in substitution thereof) that bears or is required under this
Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Exhibit B, collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legend below and the legend set forth in Exhibit B) unless such restrictions on transfer shall be waived
by written consent of the Company, and the holder of each such Restricted Security, by such Note holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c), the term 

  

 23 

 
“transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

 Until the expiration of the holding period applicable to sales of Restricted Securities under Rule 144(k) under the Securities Act (or any
successor provision), any certificate evidencing Restricted Security shall bear a legend in substantially the following form (or as set forth in Exhibit B, in the case of Common Stock issued upon conversion of the Notes), unless such Restricted
Security 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 sold pursuant to Rule 144 under the Securities Act or any
similar provision then in force, or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee: 
 THIS NOTE AND ANY
COMMON STOCK ISSUABLE UPON THE CONVERSION OF THIS NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE
TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION. EACH PURCHASER OF THIS NOTE IS HEREBY NOTIFIED THAT THE SELLER OF THIS NOTE MAY BE RELYING ON THE EXEMPTION FROM THE
PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 
 THIS NOTE AND ANY COMMON STOCK ISSUABLE UPON THE CONVERSION OF THIS NOTE
MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT (A) (1) TO US OR ANY OF OUR SUBSIDIARIES, (2) FOR SO LONG AS THE NOTES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A TO A PERSON WHO THE TRANSFEROR REASONABLY BELIEVES
IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT ACQUIRING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (3) PURSUANT
TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, INCLUDING UNDER RULE 144 (IF AVAILABLE), (4) TO AN INSTITUTIONAL INVESTOR THAT IS AN ACCREDITED INVESTOR WITHIN THE MEANING OF RULE 501(A)(1), (2), (3) OR (7) OF REGULATION D
UNDER THE SECURITIES ACT PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT (IF AVAILABLE) OR (5) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, AND (B) IN ACCORDANCE 

  

 24 

 
WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES AND OTHER JURISDICTIONS. 
 THIS NOTE, ANY SHARES OF COMMON STOCK ISSUABLE UPON ITS CONVERSION AND ANY RELATED DOCUMENTATION MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME TO MODIFY THE
RESTRICTIONS ON RESALES AND OTHER TRANSFERS OF THIS NOTE AND ANY SUCH SHARES TO REFLECT ANY CHANGE IN APPLICABLE LAW OR REGULATION (OR THE INTERPRETATION THEREOF) OR IN PRACTICES RELATING TO THE RESALE OR TRANSFER OF RESTRICTED SECURITIES GENERALLY.
THE HOLDER OF THIS NOTE AND SUCH SHARES SHALL BE DEEMED BY THE ACCEPTANCE OF THIS NOTE AND ANY SUCH SHARES TO HAVE AGREED TO ANY SUCH AMENDMENT OR SUPPLEMENT. 
 Any Notes that are Restricted Securities and as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for removal of the foregoing legend set forth therein have
been satisfied may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear
the restrictive legend required by this Section 2.05(c). If such Restricted Security surrendered for exchange is represented by a Global Note bearing the legend set forth in this Section 2.05(c), the principal amount of the legended Global
Note shall be reduced by the appropriate principal amount and the principal amount of a Global Note without the legend set forth in this Section 2.05(c) shall be increased by an equal principal amount. If a Global Note without the legend set
forth in this Section 2.05(c) is not then outstanding, the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary. 
 (d) Any Restricted Securities, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or
any successor provision), purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements
of the Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144). 
 (e) The Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records,
or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than the Depositary)
of any notice (including any notice of redemption) or the payment of any amount, under or with respect 

  

 25 

 
to such Notes. All notices and communications to be given to the Noteholders and all payments to be made to Noteholders under the Notes shall be given or
made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to
the customary procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this
Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members in any Global Indenture) other than to require delivery of such certificates and other documentation
or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in
its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange
and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case, the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in
the preceding paragraph, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Company may require the payment by the holder of a
sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been called for redemption
or has been properly tendered for repurchase on a Fundamental Change Repurchase Date (and not withdrawn) or has been tendered for repurchase on a Repurchase Date (and not withdrawn), as the case may be, or is to be converted pursuant to this
Indenture, shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof 

  

 26 

 
except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee
and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any Paying Agent or conversion agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof. 
 Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is
destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all
the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions
are exclusive with respect to the replacement or payment or conversion or redemption or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment or conversion or redemption or repurchase of negotiable instruments or other securities without their surrender. 
 Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating
agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the
Notes in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the
Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such
authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 6.02 and the Trustee or such authenticating
agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder. 
 Section 2.08. Cancellation of Notes. All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer shall, 

  

 27 

 
if surrendered to the Company or any paying agent to whom Notes may be presented for payment (the “Paying Agent”) or any conversion agent,
which shall initially be the Trustee, or any Note Registrar, be surrendered to the Trustee and promptly canceled by it or, if surrendered to the Trustee, shall be promptly canceled by it and no Notes shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as a
redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 
 Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices
of redemption as a convenience to Noteholders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the
“CUSIP” numbers. 
 ARTICLE 3 
 REDEMPTION AND REPURCHASE OF NOTES 
 Section 3.01. Optional Redemption of Notes. At any time on or after August 4, 2014 and prior to maturity, the Notes may be redeemed at the option of the Company, in whole or in part, upon notice as set forth in
Section 3.02, in cash at a redemption price equal to the principal amount of the Notes, plus accrued and unpaid interest (including contingent interest, if any) and additional interest, if any, to, but excluding, the date fixed for redemption.

 Section 3.02. Notice of Optional Redemption; Selection of Notes. In case the Company shall desire to exercise the right to
redeem all or, as the case may be, any part of the Notes pursuant to Section 3.01, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than five Business Days prior (or such shorter period of
time as may be acceptable to the Trustee) to the date the notice of redemption is to be mailed, the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such redemption not fewer than thirty calendar
days nor more than sixty calendar days prior to the redemption date to each holder of Notes so to be redeemed in whole or in part at its last address as the same appears on the Note Register; provided that if the Company makes such request of
the Trustee, it shall, together with such request, also give written notice of the redemption date to the Trustee, provided that the text of the notice shall be prepared by the Company. Such mailing shall be by first class mail. The notice, if
mailed in the manner herein 

  

 28 

 
provided, shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by
mail or any defect in the notice to the holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Concurrently with the mailing of any such notice of
redemption, the Company shall issue a press release announcing such redemption, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein
shall not affect the validity of the redemption notice or any of the proceedings for the redemption of any Note called for redemption. 
 Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers of the Notes being redeemed, (iii) the date fixed for redemption (which shall be a
Business Day), (iv) the redemption price at which Notes are to be redeemed, (v) the place or places of payment and that payment will be made upon presentation and surrender of such Notes, (iv) that interest accrued and unpaid to, but
excluding, the date fixed for redemption will be paid as specified in said notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue, (vii) that the holder has a right to convert the
Notes called for redemption, (viii) the Conversion Rate on the date of such notice and (ix) the time and date on which the right to convert such Notes or portions thereof pursuant to this Indenture will expire. If fewer than all the Notes
are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof
to be redeemed and shall state that, on and after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued. 
 Whenever any Notes are to be redeemed, the Company will give the Trustee written notice of the redemption date, together with an Officers’
Certificate as to the aggregate principal amount of Notes to be redeemed not fewer than thirty calendar days (or such shorter period of time as may be acceptable to the Trustee) prior to the redemption date. 
 On or prior to the redemption date specified in the notice of redemption given as provided in this Section 3.02, the Company will deposit with the
Paying Agent (or, if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 6.04) an amount of money in immediately available funds sufficient to redeem on the redemption date all the Notes
(or portions thereof) so called for redemption (other than those theretofore surrendered for conversion) at the appropriate redemption price, together with accrued interest to, but excluding, the redemption date; provided that if such payment
is made on the redemption date, it must be received by the Paying Agent, by 11:00 a.m., New York City time, on such date. The Company shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this
Section 3.02 in excess of amounts required hereunder to pay the 

  

 29 

 
redemption price and accrued interest to, but excluding, the redemption date. If any Note called for redemption is converted pursuant hereto prior to such
redemption date, any money deposited with the Paying Agent or so segregated and held in trust for the redemption of such Note shall be paid to the Company or, if then held by the Company, shall be discharged from such trust. 
 If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in
certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate. If any Note selected for redemption is submitted for conversion in part
after such selection, the portion of such Note submitted for conversion shall be deemed (so far as may be possible) to be the portion to be selected for redemption. The Notes (or portions thereof) so selected for redemption shall be deemed duly
selected for redemption for all purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the mailing of the notice of redemption. 
 Upon any redemption of less than all of the outstanding Notes, the Company and the Trustee may (but need not), solely for purposes of determining the pro rata allocation among such Notes that are unconverted and
outstanding at the time of redemption, treat as outstanding any Notes surrendered for conversion during the period of fifteen calendar days preceding the mailing of a notice of redemption and may (but need not) treat as outstanding any Note
authenticated and delivered during such period in exchange for the unconverted portion of any Note converted in part during such period. 
 Section 3.03. Payment of Notes Called for Redemption by the Company. If notice of redemption has been given as provided in Section 3.02, the Notes or portion of Notes with respect to which such notice has been given shall,
unless converted pursuant to the terms hereof, become due and payable on the date fixed for redemption and at the place or places stated in such notice at the redemption price, plus interest accrued to, but excluding, the redemption date, and unless
the Company shall default in the payment of such Notes at the redemption price, plus interest, if any, accrued to, but excluding, such date, interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after such
date and, after 5:00 p.m., New York City time, on the Trading Day immediately preceding the redemption date (unless the Company shall default in the payment of such Notes at the redemption price, together with interest accrued to such date) such
Notes shall cease to be convertible pursuant to this Indenture and, except as provided in Section 9.05 and Section 13.02, to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in
respect of such Notes except the right to receive the redemption price thereof plus accrued and unpaid interest to, but excluding, the redemption date. On presentation and surrender of such Notes at a place of payment in said notice specified, the
said Notes or the specified portions thereof shall be paid and redeemed by the Company at the redemption price, together with interest accrued thereon to, but excluding, the redemption date; provided that if the applicable 

  

 30 

 
redemption date is after the applicable Record Date and on or before an interest payment date, the interest payable on such interest payment date shall be
paid on such interest payment date to the holders of record of such Notes on the applicable Record Date instead of the holders surrendering such Notes for redemption on such date. 
 Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to the
holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented. 
 Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any notice of redemption during the continuance of a default in payment of
interest on the Notes. If any Note called for redemption shall not be so paid upon surrender thereof for redemption on the redemption date, as provided in this Section 3.03, the principal shall, until paid or duly provided for, bear interest
from and including the redemption date at a rate equal to 1% per annum above the rate borne by the Notes and such Note shall remain convertible pursuant to this Indenture until the redemption price and interest shall have been paid or duly
provided for. 
 Notes and portions of Notes that are to be redeemed pursuant to this Article 3 shall be convertible by the Holder thereof
until 5:00 p.m., New York City Time, on the Trading Day preceding the Redemption Date. 
 Section 3.04. Conversion Arrangement on Call for
Redemption. In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes by an agreement with one or more investment banks or other purchasers to purchase such Notes by paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable redemption price, together with interest accrued to, but excluding, the date fixed for redemption, of such Notes. Notwithstanding anything
to the contrary contained in this Article 3, the obligation of the Company to pay the redemption price of such Notes, together with interest accrued to, but excluding, the date fixed for redemption, shall be deemed to be satisfied and discharged to
the extent such amount is so paid by such purchasers. If such an agreement is entered into, a copy of which will be filed with the Trustee prior to the date fixed for redemption, any Notes not duly surrendered for conversion by the holders thereof
may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such holders and (notwithstanding anything to the contrary contained in Article 15) surrendered by such purchasers for conversion,
all as of immediately prior to 5:00 p.m., New York City time, on the date fixed for redemption (and the right to convert any such Notes shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of
the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the Trustee’s prior written consent, no arrangement

  

 31 

 
between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture. 
 Section 3.05. Repurchase at Option of Holders Upon a
Fundamental Change. (a) If there shall occur a Fundamental Change at any time prior to maturity of the Notes, then each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase all of such
holder’s Notes, or any portion thereof that is a multiple of $1,000 principal amount, in cash, on a date (the “Fundamental Change Repurchase Date”) specified by the Company, that is not less than 20 Business Days nor more than
35 Business Days after the date of the Company Repurchase Notice related to such Fundamental Change (or, if such day is not a Business Day, the next succeeding Business Day) at a repurchase price equal to 100% of the principal amount of the Notes
being repurchased, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date; provided that if such Fundamental Change Repurchase Date falls after a Record Date and on or prior to the corresponding interest payment
date, then the interest payable on such interest payment date shall be paid to the holders of record of the Notes on the applicable Record Date instead of the holders surrendering the Notes for repurchase on such date. 
 (b) On or before the tenth Business Day after the occurrence of a Fundamental Change, the Company shall mail or cause to be mailed to all holders of
record on the date of the Fundamental Change (and to beneficial owners as required by applicable law) a Company Repurchase Notice as set forth in Section 3.07 with respect to such Fundamental Change. The Company shall also deliver a copy of the
Company Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to Noteholders. Concurrently with the mailing of such Company Repurchase Notice, the Company shall issue a press release announcing such Fundamental Change
referred to in the Company Repurchase Notice, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of
the Company Repurchase Notice or any proceedings for the repurchase of any Note which any Noteholder may elect to have the Company redeem as provided in this Section 3.05. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity
of the proceedings for the repurchase of the Notes pursuant to this Section 3.05. 
 (c) For a Note to be so repurchased at the option
of the holder, the holder must deliver to the Paying Agent, prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date, (i) a written notice of repurchase (the “Repurchase
Notice”) in the form set forth on the reverse of the Note duly completed (if the Note is certificated) or stating the following (if the Note is represented by a Global Note): (A) the certificate number of the Note which the holder

  

 32 

 
will deliver to be repurchased or the appropriate Depositary procedures, (B) the portion of the principal amount of the Note which the holder will
deliver to be repurchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000 and (C) that such Note shall be repurchased as of the Fundamental Change Repurchase Date pursuant to the terms and conditions
specified in the Note and in this Indenture; together with (ii) such Notes duly endorsed for transfer (if the Note if certificated) or book entry transfer of such Note (if such Note is represented by a Global Note). The delivery of such Note to
the Paying Agent with, or at any time after delivery of, the Repurchase Notice (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the holder of the repurchase price therefore;
provided, however, that such repurchase price shall be so paid pursuant to this Section 3.05 only if the Notes so delivered to the Paying Agent shall conform in all respects to the description thereof in the Repurchase Notice. All
questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be determined by the Company, whose determination shall be final and binding absent manifest error. 
 (d) The Company shall repurchase from the holder thereof, pursuant to this Section 3.05, a portion of a Note, if the principal amount of such
portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note. 
 (e) The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. 

Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.05 shall be consummated by the delivery of the
consideration to be received by the holder promptly following the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note. Payment of the repurchase price for a Note for which a Repurchase
Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Notes, together with necessary endorsements, to the Paying Agent. 
 Section 3.06. Repurchase of Notes by the Company at Option of the Holder. (a) Each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase all of such
holder’s Notes, or any portion thereof that is a multiple of $1,000 principal amount, in cash, on August 1, 2014, August 1, 2017, and August 1, 2021 (each, a “Repurchase Date”), at a repurchase price of 100%
of the principal amount of the Notes being repurchased, plus accrued and unpaid interest (including contingent interest, if any) and additional interest, if any, to, but excluding, the Repurchase Date, subject to the provisions of Section 3.07
and subject to the satisfaction by the holder of the requirements set forth in Section 3.06(c). Payment of interest will be paid to the holder of record as of 5:00 p.m., New York City time, on the applicable Record Date. 
  

 33 

 (b) On or before the 20th Business Day prior to each Repurchase Date, the Company shall mail or cause to be mailed to all holders of record on such date (and to beneficial owners as
required by applicable law) a Company Repurchase Notice as set forth in Section 3.07. The Company shall also deliver a copy of the Company Repurchase Notice to the Trustee and the Paying Agent at such time as it is mailed to Noteholders.

 No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or
affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.06. 
 (c) For a Note to be so
repurchased at the option of the holder, the holder must deliver to the Paying Agent, during the period beginning at 9:00 a.m., New York City Time, on the date that is 20 Business Days prior to the applicable Repurchase Date and ending at 5:00 p.m.,
New York City Time, on the Business Day immediately preceding the applicable Repurchase Date, (i) a Repurchase Notice in the form set forth on the reverse of the Note duly completed (if the Note is certificated) or stating the following (if the
Note is represented by a Global Note): (A) the certificate number of the Note which the holder will deliver to be repurchased or the appropriate Depositary procedures, (B) the portion of the principal amount of the Note which the holder
will deliver to be repurchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000 and (C) that such Note shall be repurchased as of the Repurchase Date pursuant to the terms and conditions specified in the
Note and in this Indenture; together with (ii) such Notes duly endorsed for transfer (if the Note if certificated) or book entry transfer of such Note (if such Note is represented by a Global Note). The delivery of such Note to the Paying Agent
with, or at any time after delivery of, the Repurchase Notice (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the holder of the repurchase price therefore; provided,
however, that such repurchase price shall be so paid pursuant to this Section 3.06 only if the Notes so delivered to the Paying Agent shall conform in all respects to the description thereof in the Repurchase Notice. All questions as to
the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be determined by the Company, whose determination shall be final and binding absent manifest error. 
 (d) The Company shall repurchase from the holder thereof, pursuant to this Section 3.06, a portion of a Note, if the principal amount of such
portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note. 
 (e) The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. 

Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.06 shall be consummated by the delivery of the
consideration to be received by the holder promptly following the later of the Repurchase Date and the time of the 

  

 34 

 
book-entry transfer or delivery of the Note. Payment of the repurchase price for a Note for which a Repurchase Notice has been delivered and not withdrawn is
conditioned upon book-entry transfer or delivery of the Notes, together with necessary endorsements, to the Paying Agent.

of the delivery of such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn. 
  

 36 

 A Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office

Fundamental Change Repurchase Date or the Repurchase Date, the Company shall deposit with the Paying Agent or, if the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 6.04, an amount of cash (in
immediately available funds if deposited on the Fundamental Change Repurchase Date or the Repurchase Date, as the case may be), sufficient to pay the aggregate repurchase price of all the Notes or portions thereof that are to be repurchased as of
the Fundamental Change Repurchase Date or the Repurchase Date, as the case may be.

Repurchase Date the Paying Agent holds money sufficient to pay the repurchase price of the Notes that holders have elected to require the Company to repurchase in accordance with Section 3.05 or 3.06, as the case may be, then, on the
Fundamental Change Repurchase Date or the Repurchase Date, as the case may be, such Notes will cease to be outstanding, interest will cease to accrue and all other rights of the holders of such Notes will terminate, other than the right to receive
the repurchase price upon delivery or book-entry transfer of the Note. This will be the case whether or not book-entry transfer of the Note has been made or the Note has been delivered to the Paying Agent.

authenticate and make available for delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of any authorized denomination, in aggregate principal amount equal to the unrepurchased portion of the Notes presented.

 Section 3.11. Repayment to the Company. The Paying Agent shall return to the Company any cash that remains unclaimed, together with
interest, if any, thereon, held by them for the payment of the repurchase price; provided that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.09 exceeds the aggregate repurchase price of
the Notes or portions thereof which the Company is 

  

 37

 ARTICLE 4 
 SUBORDINATION OF NOTES 
 Section 4.01. Notes Subordinated To Senior
Indebtedness. The Company covenants and agrees, and the Trustee and each holder of the Notes by the acceptance thereof likewise covenant and agree, that all Notes shall be issued subject to the provisions of this Article 4; and each person
holding any Note, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees that all payments of the principal of, premium, if any, and interest on (and other obligations, if any, with respect to) the Notes by
the Company shall, to the extent and in the manner set forth in this Article 4, be subordinated and junior in right of payment to the prior payment in full in cash of all obligations arising under Senior Indebtedness. The Notes will be contractually
equal in right of payment to the Company’s other existing and future senior subordinated indebtedness, including the Company’s 1.375% Convertible Senior Subordinated Notes due 2025 and the Company’s 2.50% Convertible Senior
Subordinated Notes due 2024. 
 Section 4.02. No Payment On Notes In Certain Circumstances. 
 (a) No direct or indirect payment (other than in Junior Securities) by or on behalf of the Company of principal of, premium, if any, or interest on (and
other obligations, if any, with respect to) the Notes, whether pursuant to the terms of the Notes, upon acceleration, pursuant to an offer to repurchase, redemption or otherwise, will be made, if, at the time of such payment, there exists a default
in the payment of all or any portion of the obligations on any Designated Senior Indebtedness, whether at maturity, on account of mandatory redemption or prepayment, acceleration or otherwise, and such default shall not have been cured or waived in
writing or the benefits of this sentence waived in writing by or on behalf of the holders of such Designated Senior Indebtedness. In addition, during the continuance of any non-payment event of default with respect to any Designated Senior
Indebtedness pursuant to which the maturity thereof may be immediately accelerated by the holder or holders of such Designated Senior Indebtedness or may be accelerated by the holder or holders of such Designated Senior Indebtedness with the giving
of notice or the passage of time or both, and upon receipt by the Trustee of written notice (a “Payment Blockage Notice”) from the holder or holders of such Designated Senior Indebtedness or the trustee or agent acting on behalf of
the holders of such Designated Senior Indebtedness, then, unless and until such event of default has been cured or waived in writing or has ceased to exist or such Designated Senior Indebtedness has been discharged or repaid in full in cash (or such
payment shall be duly 

  

 38 

 
provided for in a manner satisfactory to holders of Senior Indebtedness) or otherwise to the extent holders of Senior Indebtedness in their sole discretion
accept satisfaction of amounts due by settlement in other than cash or the benefits of these provisions have been waived in writing by the holders of such Designated Senior Indebtedness, no direct or indirect payment (other than in Junior
Securities) will be made by or on behalf of the Company of principal of, premium, if any, or interest on (and other obligations, if any, with respect to) the Notes, whether pursuant to the terms of the Notes, upon acceleration, pursuant to an offer
to repurchase, redemption or otherwise to such holders during a period (a “Payment Blockage Period”) commencing on the date of receipt of the Payment Blockage Notice by the Trustee and ending 179 days thereafter. The Trustee shall
deliver a copy of the Payment Blockage Notice to the Company promptly upon receipt thereof. 
 Notwithstanding anything in the subordination
provisions of this Indenture or the Notes to the contrary, (1) in no event will a Payment Blockage Period extend beyond 179 days from the date the Payment Blockage Notice in respect thereof was given and (2) not more than one Payment
Blockage Period may exist with respect to the Notes during any period of 360 consecutive calendar days. No default that existed or was continuing on the date of delivery of any Payment Blockage Notice (whether or not such event is with respect to
the same issue of Designated Senior Indebtedness) may be, or be made, the basis for a subsequent Payment Blockage Notice, unless such default has been cured or waived for a period of not less than 90 consecutive calendar days. 
 (b) In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee or any holder at a time when such payment is
prohibited by Section 4.02(a), such payment shall be received and held in trust for the benefit of, and shall be paid over or delivered to, the holders of Designated Senior Indebtedness or their respective representatives, or to the trustee or
trustees or agent or agents under any indenture or agreement pursuant to which any of such Designated Senior Indebtedness may have been issued or incurred, as their respective interests may appear, but only to the extent that, upon notice from the
Trustee to the holders of Designated Senior Indebtedness that such prohibited payment has been made, the holders of the Designated Senior Indebtedness (or their representative or representatives or a trustee or trustees) notify the Trustee in
writing of the amounts then due and owing on the Designated Senior Indebtedness, if any, and only the amounts specified in such notice to the Trustee shall be paid to the holders of Designated Senior Indebtedness. 
 Section 4.03. Payment Over Of Proceeds Upon Dissolution, Etc. 
 (a) Upon any payment or distribution of assets or securities of the Company of any kind or character, whether in cash, property or securities, to the creditors of the Company upon any dissolution or winding-up or
total liquidation or reorganization of the Company, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or other similar proceedings relating to the Company, any assignment for the benefit of 

  

 39 

 
creditors or any marshalling of the Company’s assets and liabilities, the holders of Senior Indebtedness shall be entitled to receive payment in full in
cash of all obligations due in respect of such Senior Indebtedness (including interest accruing after, or which would accrue but for, the commencement of any proceeding at the rate specified in the applicable Senior Indebtedness, whether or not a
claim for such interest would be allowed), or have provision made for such payment in a manner acceptable to holders of such Senior Indebtedness, before the holders of the Notes or the Trustee on behalf of such holders shall be entitled to receive
any payment by the Company of the principal of, premium, if any, or interest on (and other obligations, if any, with respect to) the Notes, or any payment by the Company to acquire any of the Notes for cash, property or securities, or any
distribution by the Company with respect to the Notes of any cash, property or securities (in each case, other than payments in Junior Securities). 
 (b) In the event that, notwithstanding the foregoing provision prohibiting such payment or distribution, any payment or distribution of assets or securities of the Company of any kind or character, whether in cash, property or securities
(in each case, other than Junior Securities), shall be received by the Trustee or any Paying Agent or any holder of Notes at a time when such payment or distribution is prohibited by Section 4.03(a) and before all obligations in respect of
Senior Indebtedness are paid in full in cash (or such payment shall be duly provided for in a manner satisfactory to the holders of Senior Indebtedness) or otherwise to the extent holders of Senior Indebtedness in their sole discretion accept
satisfaction of amounts due by settlement in other than cash, such payment or distribution shall be received and held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness (pro rata to such holders
on the basis of the respective amounts of Senior Indebtedness held by such holders) or their respective representatives, or to the trustee or trustees or agent or agents under any indenture or agreement pursuant to which any of such Senior
Indebtedness may have been issued or incurred, as their respective interests may appear, for application to the payment of Senior Indebtedness remaining unpaid until all such Senior Indebtedness has been paid in full in cash (or such payment shall
be duly provided for in a manner satisfactory to the holders of Senior Indebtedness) or otherwise to the extent holders of Senior Indebtedness in their sole discretion accept satisfaction of amounts due by settlement in other than cash after giving
effect to any prior or concurrent payment, distribution or provision therefor to or for the holders of such Senior Indebtedness. 
 The
consolidation of the Company with, or the merger of the Company with or into, another corporation or limited liability company or the liquidation or dissolution of the Company following the sale, conveyance, transfer or lease of the Company’s
and its subsidiaries’ property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided in Article 12 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Article 4 if such other corporation shall, as a part of such consolidation, merger, sale, conveyance, transfer or lease, comply with the conditions stated in Article 12. 
  

 40 

 Section 4.04. Subrogation. Upon the payment in full in cash (or such payment shall be duly
provided for in a manner satisfactory to the holders of Senior Indebtedness) or otherwise to the extent holders of Senior Indebtedness in their sole discretion accept satisfaction of amounts due by settlement in other than cash of all Senior
Indebtedness, the holders of the Notes shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, cash equivalents, property or securities of the Company made on such Senior Indebtedness
until the principal of, premium, if any, and interest on the Notes shall be paid in full in cash or the Notes are no longer outstanding; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, cash equivalents, property or securities to which the holders of the Notes or the Trustee on their behalf would be entitled except for the provisions of this Article 4, and no payment over pursuant to the provisions of this
Article 4 to the holders of Senior Indebtedness by holders of the Notes or the Trustee on their behalf shall, as between the Company, its creditors other than holders of Senior Indebtedness, and the holders of the Notes, be deemed to be a payment by
the Company to or on account of the Senior Indebtedness. It is understood that the provisions of this Article 4 are and are intended solely for the purpose of defining the relative rights of the holders of the Notes, on the one hand, and the holders
of the Senior Indebtedness, on the other hand. 
 If any payment or distribution to which the holders of the Notes would otherwise have been
entitled but for the provisions of this Article 4 shall have been applied, pursuant to the provisions of this Article 4, to the payment of all amounts payable under Senior Indebtedness, then and in such case, the holders of the Notes shall be
entitled to receive from the holders of such Senior Indebtedness any payments or distributions received by such holders of Senior Indebtedness in excess of the amount required to make payment in full in cash of such Senior Indebtedness (or to duly
provide for such payment in a manner satisfactory to the holders of Senior Indebtedness) or otherwise to the extent holders of Senior Indebtedness in their sole discretion accept satisfaction of amounts due by settlement in other than cash.

 Section 4.05. Obligations Of Company Unconditional. Nothing contained in this Article 4 or elsewhere in this Indenture or in the
Notes is intended to or shall impair, as among the Company and the holders of the Notes, the obligation of the Company, which is absolute and unconditional, to pay to the holders of the Notes the principal of, premium on and interest on the Notes as
and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Notes and creditors of the Company other than the holders of the Senior Indebtedness, nor
shall anything herein or therein prevent the holder of any Note or the Trustee on their behalf from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 4
of the holders of the Senior Indebtedness in respect of cash, cash equivalents, property or securities of the Company received upon the exercise of any such remedy. 
  

 41 

 Without limiting the generality of the foregoing, nothing contained in this Article 4 shall restrict the
right of the Trustee or the holders of Notes to take any action to declare the Notes to be due and payable prior to their stated maturity pursuant to Section 8.01 or to pursue any rights or remedies hereunder; provided, however,
that all Senior Indebtedness then due and payable shall first be paid in full in cash (including Post-Petition Interest), or have provision made for such payment in a manner satisfactory to the holders of such Senior Indebtedness, before the holders
of the Notes or the Trustee are entitled to receive any direct or indirect payment from the Company of principal of, premium and interest on (and other obligations, if any, with respect to) the Notes. 
 Section 4.06. Notice To Trustee. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit
the making of any payment to or by the Trustee in respect of the Notes pursuant to the provisions of this Article 4. Unless the Trustee has failed to give notice of its change of address pursuant to Section 16.03 hereof, the Trustee shall not
be charged with knowledge of the existence of any event of default with respect to any Senior Indebtedness or of any other facts which would prohibit the making of any payment to or by the Trustee unless and until the Trustee shall have received
notice in writing at its Corporate Trust Office to that effect signed by an Officer of the Company, or by a holder of Senior Indebtedness or trustee or agent therefor; and prior to the receipt of any such written notice, the Trustee subject to the
provisions of Article 9 shall, be entitled to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 4.06 at least two Business Days prior to the date upon which
by the terms of this Indenture any moneys shall become payable for any purpose (including, without limitation, the payment of the principal of, premium, if any, or interest on any Note), then, regardless of anything herein to the contrary, the
Trustee shall have full power and authority to receive any moneys from the Company and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after
such prior date. Nothing contained in this Section 4.06 shall limit the right of the holders of Senior Indebtedness to recover payments as contemplated by Section 4.03 or from any holder under Section 4.02(b). The Trustee shall be
entitled to conclusively rely on the delivery to it of a written notice by a Person representing himself or itself to be a holder of any Senior Indebtedness (or a trustee on behalf of, or agent or other representative of, such holder) to establish
that such notice has been given by a holder of such Senior Indebtedness or a trustee or agent or representative on behalf of any such holder. A holder of Senior Indebtedness and any trustee, agent or other representative on behalf of such holder
shall be entitled to deliver all notices required by this Section 4.06 or otherwise pursuant to this Article 4 to the address of the Trustee set forth herein unless such holder or the trustee, agent or representative of such holder shall have
received actual written notice of a change of address of the Trustee. 
 In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in 

  

 42 

 
any payment or distribution pursuant to this Article 4, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee
as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 4, and if such
evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 Section 4.07. Trustee’s Relation To Senior Indebtedness. The Trustee and any Paying Agent shall be entitled to all the rights set forth in this Article 4 with respect to any Senior Indebtedness which may
at any time be held by it in its individual or any other capacity to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee or any Paying Agent of any of its rights as such holder.

 With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article 4, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Indebtedness (except as provided in Section 4.02(b) and 4.03(b)). The Trustee shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to holders of
Notes or to the Company or to any other person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 4 or otherwise. 
 Section 4.08. Subordination Rights Not Impaired By Acts Or Omissions Of The Company Or Holders Of Senior Indebtedness. No right of any present or
future holders of any Senior Indebtedness to enforce subordination as provided herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company with the terms of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. The provisions of this Article 4 are intended to be for the
benefit of, and shall be enforceable directly by, the holders of Senior Indebtedness. 
 Section 4.09. Holders Authorize Trustee To
Effectuate Subordination Of Notes. Each holder of Notes by his acceptance of such Notes authorizes and expressly directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in
this Article 4, and appoints the Trustee his attorney-in-fact for such purposes, including, in the event of any dissolution, winding-up, total liquidation or reorganization of the Company (whether in bankruptcy, insolvency, receivership,
reorganization or similar proceedings or upon an assignment for the benefit of creditors or otherwise) tending towards liquidation of the business and assets of the Company, the 

  

 43 

 
filing of a claim for the unpaid balance of its or his Notes in the form required in those proceedings. 
 Section 4.10. This Article Not To Prevent Events Of Default. The failure to make a payment on account of principal of, or premium, if any, or
interest on the Notes by reason of any provision of this Article 4 shall not be construed as preventing the occurrence of an Event of Default specified in clauses (a) or (b) of Section 8.01. 
 Section 4.11. Trustee’s Compensation And Rights To Indemnification Not Prejudiced. Nothing in this Article 4 shall apply to amounts due to
the Trustee, or its rights to indemnification, pursuant to other sections in this Indenture. 
 Section 4.12. No Waiver Of Subordination
Provisions. Without in any way limiting the generality of Section 4.08, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the holders of the Notes, without
incurring responsibility to the holders of the Notes and without impairing or releasing the subordination provided in this Article 4 or the obligations hereunder of the holders of the Notes to the holders of Senior Indebtedness, do any one or more
of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew, alter or amend, Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is
outstanding or secured; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (c) release any Person liable in any manner for the collection of Senior Indebtedness;
and (d) exercise or refrain from exercising any rights against the Company and any other Person. 
 Section 4.13. Subordination
Provisions Not Applicable To Money Held In Trust For Holders; Payments May Be Paid Prior To Dissolution. All funds deposited in trust with the Paying Agent pursuant to and in accordance with Article 13 when permitted pursuant to Article 4 shall
be for the sole benefit of the holders and shall not be subject to this Article 4. 
 Nothing contained in this Article 4 or elsewhere in
this Indenture shall prevent (i) the Company, except under the conditions described in this Article 4, from making payments of principal of, premium, if any, and interest on the Notes or from depositing with the Paying Agent any moneys for such
payments or from effecting a termination of the Company’s obligations under the Notes and this Indenture as provided in Article 13, or (ii) the application by the Trustee of any moneys deposited with it or any Paying Agent for the purpose
of making such payments of principal of, premium, if any, and interest on the Notes, to the holders entitled thereto unless at least two Business Days prior to the date upon which such payment becomes due and payable, the Trustee shall have received
the written notice provided for in Section 4.02(b) or in Section 4.06. The Company shall give prompt written notice to the Trustee of any dissolution, winding-up, liquidation or reorganization of the Company. 
  

 44 

 Section 4.14. Acceleration Of Notes. If payment of the Notes is accelerated because of an Event of
Default, the Company shall promptly notify holders of the Senior Indebtedness of the acceleration. 
 Section 4.15. Certain Conversions
and Repurchases Not Deemed Payment. For the purposes of this Article 4 only, the issuance and delivery of Junior Securities, if any, upon conversion of Notes in accordance with, and the payment, issuance or delivery of cash, property or
securities upon conversion of a Note as a result of any transaction pursuant to, Section 15.01 shall not be deemed to constitute a payment or distribution on account of the principal of, premium, if any, or interest on Notes or on account of
the purchase or other acquisition of Notes. For the purposes of this Article 4, the term “Junior Securities” means (a) Common Stock of the Company, or (b) securities of the Company that are subordinated in right of payment
to all Senior Indebtedness that may be outstanding at the time of issuance or delivery of such securities to at least the same extent as, or to a greater extent than, the Notes are so subordinated as provided in this Article 4. Nothing contained in
this Article 4 or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors (other than holders of Senior Indebtedness) and the Noteholders, the right, which is absolute and unconditional, of the
holder of any Note to convert such Note in accordance with Section 15.01. 
 ARTICLE 5 
 CONTINGENT INTEREST 
 Section 5.01. Contingent Interest. Beginning with the six-month interest period commencing August 4, 2014, the Company will pay contingent interest during any six-month interest period if the Trading Price of the Notes for each
of the five Trading Days ending on the second Trading Day immediately preceding the first day of the applicable six-month interest period equals or exceeds 120% of the principal amount of the Notes. During any six-month interest period when
contingent interest is payable, the contingent interest payable on each $1,000 principal amount of Notes shall equal 0.25% of the average Trading Price of $1,000 principal amount of Notes during the five Trading Days immediately preceding the first
day of the applicable six-month interest period used to determine whether contingent interest must be paid. 
 The Trustee’s sole
responsibility pursuant to Section 5.01 hereof shall be to obtain the Trading Price of the Notes for each of the five Trading Days immediately preceding the first day of the applicable six-month interest period and to provide such information
to the Company. The Company shall determine whether holders are entitled to receive contingent interest, and if so, provide notice pursuant to Section 5.03. Notwithstanding any term contained in this Indenture or any other document to the
contrary, the Trustee shall have no responsibilities, duties or obligations for or with respect to (i) determining whether the Company must pay contingent interest or (ii) determining the amount of contingent interest, if any, payable by
the Company. 
  

 45

period shall be paid on the applicable interest payment date to the Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the corresponding Record Date. Contingent interest due under this Article 5 shall be

the Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of
reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment
shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb
or prejudice the rights of any other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable
and common benefit of all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 8.04, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law

dates expressed in such Note or in the event of redemption or repurchase, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of
such holder. 
 Anything contained in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the
consent of either the Trustee or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein. 
 Section 8.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its discretion, proceed to protect and enforce
the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

 Section 8.06. Remedies Cumulative and Continuing. Except as provided in Section 2.06, all powers and remedies given by
this Article 8 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon
any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 8.04,
every power and remedy given by this Article 8 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders. 
 Section 8.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal amount
of the Notes at the time outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided that
(a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action which is not inconsistent with such direction, (c) the Trustee may decline to take any action that
would 

  

 58 

 
benefit some Noteholder to the detriment of other Noteholders and (d) the Trustee may decline to take any action that would involve the Trustee in
personal liability. The holders of a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf of the holders of all of the Notes, waive any past default or Event of Default hereunder and its consequences
except (i) a default in the payment of the principal of, premium, if any, or interest on the Notes, (ii) a failure by the Company to convert any Notes as required by this Indenture, (iii) a default in the payment of the
redemption price on the redemption date pursuant to Article 3, (iv) a default in the payment of the repurchase price on the Fundamental Change Repurchase Date or the Repurchase Date pursuant to Article 3 or (v) a default in respect of a
covenant or provisions hereof which under Article 11 cannot be modified or amended without the consent of the holders of all Notes then outstanding or each Note affected thereby. Upon any such waiver, the Company, the Trustee and the holders of the
Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder
shall have been waived as permitted by this Section 8.07, said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent thereon. 
 Section 8.08. Notice of Defaults.
The Trustee shall, within ninety calendar days after a Responsible Officer of the Trustee has knowledge of the occurrence of a default, mail to all Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of
all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; provided that except in the case of default in the payment of the principal of, or premium, if any, or
interest on any of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in
the interests of the Noteholders. 
 Section 8.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each
holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and
expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 8.09 (to the extent permitted by law)
shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten percent in principal amount of the Notes at the time outstanding determined in
accordance with Section 10.04, or to any suit instituted by any Noteholder for the enforcement of the 

  

 59 

 
payment of the principal of, or premium, if any, or interest on any Note on or after the due date expressed in such Note or to any suit for the enforcement
of the right to convert any Note in accordance with the provisions of Article 15. 
 ARTICLE 9 
 THE TRUSTEE 
 Section 9.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. 
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred: 
 (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust
Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust
Indenture Act against the Trustee; and 
 (ii) in the absence of bad faith and willful misconduct on the part of the Trustee,
the Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the
case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of
this Indenture; 
 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of
the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts; 
 (c) the Trustee shall not be liable with respect to any
action taken or omitted to be taken by it in good faith in accordance with the written direction of the holders of not 

  

 60 

 
less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 10.04 relating to the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section;

 (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other
matters relating to payment) or notice effected by the Company or any Paying Agent (other than the Trustee) or any records maintained by any co-registrar (other than the Trustee) with respect to the Notes; 
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee,
the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred unless a Responsible Officer of the Trustee has actual knowledge thereof or unless the Trustee has otherwise received written
notice thereof; and 
 (g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless a Responsible Officer
of the Trustee has actual knowledge thereof or unless the Trustee shall have been notified in writing of such Event of Default by the Company or a holder of Notes. 
 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
 Section 9.02. Reliance on Documents, Opinions, etc. Except as otherwise provided in Section 9.01: 
 (a) the Trustee may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, debenture, note, coupon or other paper or document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 

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

 61 

 (c) the Trustee may consult with counsel of its own selection and any advice or Opinion of Counsel shall
be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in reliance on and in accordance with such advice or Opinion of Counsel; 
 (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of
any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee reasonable security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby; 
 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee may make such further inquiry or investigation into such facts or matters as it
may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; 
 (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys
and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder; 
 (g) the Trustee shall not be liable for any action taken, suffered or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon
it by this Indenture; 
 (h) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without
limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; 
 (i) the Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such
certificate previously delivered and not superseded; and 
 (j) any permissive right or authority granted to the Trustee shall not be
construed as a mandatory duty. 
 Section 9.03. No Responsibility for Recitals, etc. The recitals contained herein and in the Notes
(except in the Trustee’s certificate of authentication) shall be taken as 

  

 62 

 
the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the
provisions of this Indenture. 
 Section 9.04. Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The Trustee, any
Paying Agent, any conversion agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, Paying Agent, conversion agent or Note Registrar.

 Section 9.05. Monies to be Held in Trust. Subject to the provisions of Section 13.02, all monies received by the
Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law.
Except as otherwise provided herein, the Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee. 
 Section 9.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to
time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the
provisions of this Indenture (including the reasonable compensation and the reasonable expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its
negligence, willful misconduct, recklessness or bad faith. The Company also covenants to indemnify the Trustee and any predecessor Trustee (or any officer, director or employee of the Trustee), in any capacity under this Indenture and any
authenticating agent for, and to hold them harmless against, any and all loss, liability, damage, claim or reasonable expense including taxes (other than taxes based on the income of the Trustee) incurred without negligence, willful misconduct,
recklessness or bad faith on the part of the Trustee or such officers, directors, employees or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity
hereunder, including the reasonable costs and expenses of defending themselves against any claim (whether asserted by the Company, any holder or any other Person) of liability in the premises. The obligations of the Company under this
Section 9.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for reasonable expenses, disbursements and 

  

 63 

 
advances shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in
trust for the benefit of the holders of particular Notes. The obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture. 
 When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 8.01(e) or (f) with respect to the Company occurs, the expenses
and the compensation for the services are intended to constitute reasonable expenses of administration under any bankruptcy, insolvency or similar laws. 
 Section 9.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 9.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or
desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, bad faith,
recklessness or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee. 
 Section 9.08. Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
 Section 9.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the
Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least
$50,000,000). If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.09, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 9.10. Resignation or Removal of
Trustee. 
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the holders of
Notes. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty calendar days after the mailing of such notice of resignation to the 

  

 64 

 
Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Noteholders, appoint a successor identified in such notice
or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the
provisions of Section 8.094, on behalf of itself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee. 
 (b) In case at any time any of the following shall occur: 
 (i) the Trustee shall fail to comply with Section 9.08 after written request therefor by the Company or by any Noteholder who has
been a bona fide holder of a Note or Notes for at least six months; or 
 (ii) the Trustee shall cease to be eligible in
accordance with the provisions of Section 9.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder; or 
 (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; 
 then, in any such case, the Company may
remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to the provisions of Section 8.094, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee; provided that if no successor Trustee shall have been appointed and have accepted appointment sixty calendar days after either the Company or the Noteholders has removed
the Trustee, or the Trustee resigns, the Trustee so removed may petition, at the expense of the Company, any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may
deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The holders of a majority in aggregate principal amount
of the Notes at the time outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless, within ten calendar days after notice to the Company of such nomination, the
Company objects thereto, in which case the Trustee so removed or any Noteholder, or if such Trustee so removed or any Noteholder fails to act, the Company, upon the terms and conditions and otherwise as in 

  

 65 

 
Section 9.10(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 9.10 shall
become effective upon acceptance of appointment by the successor trustee as provided in Section 9.11. 
 (e) Notwithstanding the
replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 9.06 shall continue for the benefit of the retiring Trustee. 
 Section 9.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 9.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amount then due it pursuant to the provisions of Section 9.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a
lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 9.06. 

No successor trustee shall accept appointment as provided in this Section 9.11 unless, at the time of such acceptance, such successor trustee
shall be qualified under the provisions of Section 9.08 and be eligible under the provisions of Section 9.09. 
 Upon acceptance of
appointment by a successor trustee as provided in this Section 9.11, the Company (or the former trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the holders
of Notes at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten (10) calendar days after acceptance of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company. 
 Section 9.12. Succession by Merger. Any corporation into which the Trustee may
be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate
trust business of the Trustee (including any trust created by this Indenture), shall be the 

  

 66 

 
successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided
that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 9.08 and eligible under the provisions of
Section 9.09. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the
Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of the successor
trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Indenture; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes
in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
 Section
9.13. Preferential Collection of Claims. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the
collection of the claims against the Company (or any such other obligor). 
 ARTICLE 10 
 THE NOTEHOLDERS 
 Section 10.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request,
the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of Noteholders, or (c) by a combination
of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such
solicitation a date as the record date for determining holders entitled to take such action. The record date shall be not more than fifteen calendar days prior to the date of commencement of solicitation of such action. 
 Section 10.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 9.01 and 9.02, proof of the execution of any
instrument by a Noteholder or its 

  

 67 

 
agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as
shall be satisfactory to the Trustee. The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar. 
 Section 10.03. Absolute Owners. The Company, the Trustee, any Paying Agent, any conversion agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to be, and may treat it
as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving
payment of or on account of the principal of, premium, if any, and interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any conversion agent nor any Note
Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability
for monies payable upon any such Note. 
 Section 10.04. Company-Owned Notes Disregarded. In determining whether the holders of the
requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or any Affiliate of the Company or any other
obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction,
consent, waiver or other action, only Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 10.04 if
the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Company, any other obligor on the Notes or any Affiliate of the Company or any such other obligor. In the case
of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing
and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons, and, subject to Section 9.01, the Trustee shall be entitled to accept such Officers’ Certificate as
conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 
 Section 10.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 10.01, of the taking of any action by the holders of
the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note which is shown by the evidence to be included in the Notes the holders of which have consented to 

  

 68 

 
such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 10.02, revoke
such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in exchange
or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor. 
 ARTICLE 11 
 SUPPLEMENTAL INDENTURES 
 Section 11.01. Supplemental Indentures Without Consent of Noteholders. The Company, when authorized by the resolutions of the Board of Directors,
and the Trustee may, from time to time, and at any time enter into an indenture or indentures supplemental without the consent of the holders of the Notes hereto for one or more of the following purposes: 
 (a) make provision with respect to the conversion rights of the holders of Notes and the repurchase obligations of the Company in connection with a
Fundamental Change pursuant to the requirements of Section 15.06; 
 (b) to convey, transfer, assign, mortgage or pledge to the Trustee,
as security for the Notes, any property or assets; 
 (c) to evidence the succession of another Person to the Company, or successive
successions, and the assumption by the successor Person of the covenants, agreements and obligations of the Company pursuant to Article 12; 
 (d) to add to the covenants of the Company such further covenants, restrictions or conditions as the Board of Directors and the Trustee shall consider to be for the benefit of the holders of Notes, and to make the occurrence, or the
occurrence and continuance, of a default in any such additional covenants, restrictions or conditions a default or an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set
forth; provided that in respect of any such additional covenant, restriction or condition, such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the
case of other defaults) or may provide for an immediate enforcement upon such default or may limit the remedies available to the Trustee upon such default; 
 (e) surrender any right or power herein conferred upon the Company; 
 (f) to cure any ambiguity or to
correct or supplement any provision contained herein or in any supplemental indenture that may be defective or inconsistent with any other provision contained herein or in any supplemental indenture provided that such 

  

 69 

 
action does not adversely affect the interests of the holders of the Notes in any material respect; 
 (g) add or modify any provisions herein with respect to matters or questions arising hereunder which the Company may deem necessary or desirable and that
shall not be inconsistent with the provisions of this Indenture; provided, that such change or modification pursuant to this clause (g) does not, in the good faith determination of the Board of Directors (as evidenced by a resolution of
the Board of Directors), adversely affect the interests of the holders of the Notes in any material respect; 
 (h) increase the Conversion
Rate; provided, however, that such increase in the Conversion Rate shall not adversely affect the interests of the holders of the Notes (after taking into account tax and other consequences of such increase); 
 (i) make any changes or modifications necessary in connection with the registration of the Notes under the Securities Act as contemplated in the
Registration Rights Agreement; provided that such change or modification pursuant to this clause (i) does not adversely affect the interests of the holders of the Notes in any material respect; 
 (j) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Notes; or 
 (k) to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to effect or maintain the qualification of this
Indenture under the Trust Indenture Act, or under any similar federal statute hereafter enacted. 
 Upon the written request of the Company,
accompanied by a copy of the resolutions of the Board of Directors certified by its Secretary or Assistant Secretary authorizing the execution of any supplemental indenture, the Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained and to accept the conveyance, transfer and assignment of any property thereunder, but the Trustee shall not be obligated
to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this Section 11.01 may be executed by the Company and the Trustee without the consent of the holders of any of the Notes at the time outstanding,
notwithstanding any of the provisions of Section 11.02. 
 Section 11.02. Supplemental Indenture With Consent of Noteholders.

 70 

 
any time, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided that no such supplemental indenture shall, without the consent of the holder of each Note so
affected: 
 (i) extend the fixed maturity of any Note; 
 (ii) reduce the rate or extend the time for payment of interest on any Note; 
 (iii) reduce the principal amount of any Note or premium, if any, on any Note; 
 (iv) reduce any amount payable on redemption or repurchase of any Note;

 (x) affect the right of a
holder to convert any Note or to reduce the cash or number of shares of Common Stock, if any, or any other property receivable upon conversion pursuant to the terms set forth herein, including Section 15.06; 
 (xi) modify any of the provisions of this Section 11.02 or Section 8.07, except to increase any such percentage or to provide

 Upon the written request of the
Company, accompanied by a copy of the resolutions of the Board of Directors certified by the Company’s Secretary or Assistant Secretary authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of
evidence of the consent of Noteholders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
 It shall not be necessary for the consent of the Noteholders under this Section 11.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance
thereof. 
 Section 11.03. Effect of Supplemental Indenture. Any supplemental indenture executed pursuant to the provisions of this
Article 11 shall comply with the Trust Indenture Act, as then in effect, provided that this Section 11.03 shall not require such supplemental indenture or the Trustee to be qualified under the Trust Indenture Act prior to the time, if
ever, such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to such supplemental
indenture that any such qualification is required prior to the time, if ever, such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act. Upon the execution of
any supplemental indenture pursuant to the provisions of this Article 11, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Notes shall thereafter be determined, exercised and enforced hereunder, subject in all respects to such modifications and amendments and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 Section
11.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 11 may bear a notation in form approved by the Trustee as to any matter provided for in
such 

  

 72 

 
supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the
Trustee pursuant to Section 16.11) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. 
 Section 11.05. Evidence of Compliance of Supplemental Indenture to be Furnished to Trustee. Prior to entering into any supplemental indenture pursuant to this Article 11, the Trustee shall be provided with an Officers’
Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 11 and is otherwise authorized or permitted by this Indenture. 
 ARTICLE 12 
 CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 
 Section 12.01. Company May Consolidate on Certain Terms. Subject to the provisions of Section 12.02, the Company shall not, in a single transaction or a series of related transactions, consolidate or merge
with or into any other Person or Persons (whether or not affiliated with the Company), nor shall the Company sell, convey, transfer or lease the property and assets of the Company substantially as an entirety, to any other Person (whether or not
affiliated with the Company), unless: (i) the Company is the continuing corporation, or the resulting, surviving or transferee Person (if other than the Company) is a corporation or limited liability company organized and existing under the
laws of the United States of America, any state thereof or the District of Columbia; (ii) upon any such consolidation, merger, sale, conveyance, transfer or lease, the due and punctual payment of the principal of, and premium, if any, and
interest on all of the Notes, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or satisfied by the Company, shall be expressly assumed by a supplemental indenture reasonably
satisfactory in form to the Trustee and all of the obligations of the Company under the Registration Rights Agreement shall be expressly assumed by a supplemental agreement, in each case, executed and delivered to the Trustee by the Person (if other
than the Company) formed by such consolidation, or into which the Company shall have been merged, or by the Person that shall have acquired or leased such property, and such supplemental indenture shall provide for the applicable conversion rights
set forth in Section 15.06; (iii) immediately after giving effect to the transaction described above, no default or Event of Default, has occurred and is continuing; and (iv) the Company has delivered to the Trustee the Officers’
Certificate and Opinion of Counsel, if any, requested pursuant to Section 12.03. 
  

 73 

 Section 12.02. Successor to be Substituted. In case of any such consolidation, merger, sale,
conveyance, transfer or lease in which the Company is not the continuing corporation and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the
Trustee, of the due and punctual payment of the principal of, and premium, if any, and interest on all of the Notes, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or
satisfied by the Company, and by supplemental agreement, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of all of the obligations of the Company under the Registration Rights Agreement, such successor
Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of this first part, and Advanced Medical Optics, Inc. shall be discharged from its obligations under the Notes, this
Indenture and the Registration Rights Agreement. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of Advanced Medical Optics, Inc. any or all of the Notes, issuable hereunder that
theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the
Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes that such
successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance, transfer or lease, upon compliance with this Article 12
the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time
thereafter and such Person shall be discharged from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture. 
 In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

 Section 12.03. Opinion of Counsel to be Given Trustee. Prior to execution of any supplemental indenture pursuant to this Article
12, if so requested by the Trustee, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies
with the provisions of this Article 12. 
  

 74 

 ARTICLE 13 
 SATISFACTION AND DISCHARGE OF INDENTURE 
 Section 13.01. Discharge of Indenture. When (a) the Company shall deliver to the Trustee for cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in
substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable, or are
by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Company shall deposit with the Trustee, in
trust, funds sufficient to pay at maturity or upon redemption all of the Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and
delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and premium, if any, and interest due or to become due to such date of maturity or redemption date, as the case may be, accompanied by a
verification report, as to the sufficiency of the deposited amount, from an independent certified accountant or other financial professional satisfactory to the Trustee, and if the Company shall also pay or cause to be paid all other sums payable
hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (4) remaining rights of registration of transfer, substitution and exchange and conversion of Notes, (5) rights hereunder of Noteholders to
receive payments of principal of and premium, if any, and interest on the Notes and the other rights, duties and obligations of Noteholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and
(iii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section 16.05 and at the cost
and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly
incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. 
 Section 13.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 13.04, all monies deposited with the Trustee pursuant to
Section 9.05, shall be held in trust for the sole benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent),
to the holders of the particular Notes for the payment or redemption of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest. Moneys so held in trust shall not
be subject to the provisions of Article 4. All moneys deposited with the Trustee pursuant to Section 9.05 (and held by it or any Paying Agent) for the payment of Notes subsequently converted shall be returned to the Company upon 

  

 75 

 
request. The Trustee is not responsible to anyone for interest on any deposited funds except as agreed in writing. 
 Section 13.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any Paying Agent
(other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies. 
 Section 13.04. Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for
payment of the principal of, premium, if any, or interest on Notes and not applied but remaining unclaimed by the holders of Notes for two years after the date upon which the principal of, premium, if any, or interest on such Notes, as the case may
be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the Notes shall thereafter look only to the
Company for any payment that such holder may be entitled to collect unless an applicable abandoned property law designates another Person. 
 Section 13.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 13.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.01 until such time as the Trustee or the Paying
Agent is permitted to apply all such money in accordance with Section 13.02; provided that if the Company makes any payment of principal of or premium, if any, or interest on any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 14 
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
OFFICERS AND DIRECTORS 
 Section 14.01. Indenture and Notes Solely Corporate
Obligations. No recourse for the payment of the principal of or, premium, if any, or interest on any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the
Company in this Indenture or in any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, member, manager, employee, agent, officer, director or
subsidiary, as such, past, present or future, of the Company or any of the Company’s subsidiaries or of any successor thereto, either directly or through the Company or any of the Company’s subsidiaries or any successor thereto, whether by
virtue of any constitution, statute or rule of law, or by the 

  

 76 

 
enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes. 
 ARTICLE 15 
 CONVERSION OF NOTES 
 Section 15.01. Right to Convert. 
 (a) Subject to and upon compliance with the provisions of this
Indenture, on or prior to the Trading Day immediately preceding the Maturity Date, the holder of any Note not previously redeemed or repurchased shall have the right, at such holder’s option, to convert the principal amount of the Note, or any
portion of such principal amount which is a multiple of $1,000, into cash or, as provided herein, cash and Common Stock, at the Conversion Rate in effect at such time, by surrender of the Note so to be converted in whole or in part, together with
any required funds, under the circumstances and in the manner described in this Article 15; provided, however, that at any time prior to the close of business on the Trading Day preceding July 1, 2014, holders may convert their
Notes only upon occurrence of one of the following events: 
 (i) during the five Business Days immediately following any five
consecutive Trading-Day period in which the Trading Price per $1,000 principal amount of the Notes for each day of such five Trading-Day period was less than 98% of the product of the Closing Sale Price of a share of Common Stock and the Conversion
Rate in effect on each such Trading Day; 
 (ii) as provided in Section (b) of this Section 15.01; or 
 (iii) if a Fundamental Change occurs, at any time beginning 15 calendar days prior to the date announced by the Company as the anticipated
effective date of the Fundamental Change and until and including the date which is 15 calendar days after the date that is the Effective Date (subject to expiration of such conversion right if any holder has submitted any or all of its Notes for
repurchase as set forth under Section 3.05); or 
 (iv) during any fiscal quarter after the fiscal quarter ending
September 30, 2006, the Closing Sale Price of the shares of Common Stock for any 20 or more consecutive Trading Days in any 30 consecutive Trading-Day period ending on the last trading day of the immediately preceding fiscal quarter exceeds
130% of the Conversion Rate in effect on the last Trading Day of the immediately preceding calendar quarter. 
  

 77 

 Notes and portions of Notes that are to be redeemed pursuant to Article 3 shall be convertible by the
Holder thereof until 5:00 p.m., New York City Time, on the Trading Day preceding the Redemption Date. 
 The Trustee (or other conversion
agent appointed by the Company) shall, on behalf of the Company, determine on a daily basis during the time period specified in Section 15.01(a)(i) whether the Notes shall be convertible as a result of the occurrence of an event specified in
clause (i) above and, if the Notes shall be so convertible, the Trustee (or other conversion agent appointed by the Company) shall promptly deliver to the Company and the Trustee (if the Trustee is not the conversion agent) written notice
thereof. 
 The Trustee (or other conversion agent appointed by the Company) shall have no obligation to determine the Trading Price under
Section 15.01(a)(i) unless the Company has requested that the Trustee make such a determination; and the Company shall have no obligation to make such request unless so requested in writing by a holder that provides the Company with reasonable
evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Closing Sale Price of a share of Common Stock and the Conversion Rate then in effect. If a holder submits such a request, the Company
shall instruct the Trustee (or other conversion agent) to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or
equal to 98% of the product of the Closing Sale Price of a share of Common Stock and the Conversion Rate then in effect for five consecutive Trading Days; provided that the Trustee shall be under no duty or obligation to make the calculations
described in Section 15.01(a)(i) hereof or to determine whether the Notes are convertible pursuant to such section. For the avoidance of doubt, the Company shall make the calculations described in Section 15.01(a)(i) using the Trading
Price provided by the Trustee. If, at any point after the trading price condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the Closing Sale Price of shares of Common Stock and the
Conversion Rate then in effect, the Company shall notify the holders of Notes. 
 The Trustee shall be entitled at its sole discretion to
consult with the Company and to request the assistance of the Company in connection with the Trustee’s duties and obligations pursuant to Section 15.01(a)(i) hereof (including without limitation the calculation or determination of the
Closing Sale Price and the Trading Price), and the Company agrees, if requested by the Trustee, to cooperate with, and provide assistance to, the Trustee in carrying out its duties under this Section 15.01; provided, however, that
nothing contained herein shall be construed to relieve the Trustee of its duties pursuant to Section 15.01(a)(i) hereof. 
  

 78 

 (b) In addition, if: 
 (i) (A) the Company distributes to all holders of Common Stock rights or warrants entitling them (for a period expiring within 45 calendar
days of the record date for the determination of the stockholders entitled to receive such distribution) to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Sale Price of a share of Common
Stock for the ten Trading Days immediately preceding, but not including, the declaration date for such distribution, or (B) the Company distributes to all holders of Common Stock, cash or other assets, debt securities or rights to purchase its
securities, where the Fair Market Value of such distribution per share of Common Stock exceeds 10% of the Closing Sale Price of a share of Common Stock on the Trading Day immediately preceding the declaration date for such distribution, then, in
either case, the holders shall have the right to convert Notes at any time on and after the date that the Company gives notice to the holders of such distribution, which shall be not less than 20 calendar days prior to the Ex-Dividend Time for such
distribution, until the earlier of 5:00 p.m., New York City time, on the Business Day immediately preceding, but not including, the Ex-Dividend Time or the date the Company publicly announces that such distribution will not take place;
provided that a holder of a Note may not convert its Notes pursuant to this Section 15.01(b)(i) if the holder will otherwise participate in such distribution without conversion as a result of holding the Notes; or 
 (ii) the Company consolidates with or merges with or into another Person or is a party to a binding share exchange or conveys, transfers,
sells, leases or otherwise disposes of all or substantially all of its properties and assets in each case pursuant to which the Common Stock would be converted into cash, securities and/or other property that does not also constitute a Fundamental
Change, then the holders shall have the right to convert Notes at any time beginning fifteen calendar days prior to the date announced by the Company as the anticipated effective date of the transaction and until and including the date that is
fifteen calendar days after the date that is the actual effective date of such transaction. The Company will notify holders of Notes at least 20 days prior to the anticipated effective date of such transaction. Upon conversion, holders of the Notes
will receive the Conversion Value as determined pursuant to clause (i) of the third paragraph of Section 15.02. The Board of Directors shall determine the anticipated effective date of the transaction, and such determination shall be
conclusive and binding on the holders and shall be publicly announced by the Company and posted on its web site not later than two Business Day prior to such 15th day. 
 “Ex-Dividend Time” means, with respect to any distribution on
shares of Common Stock, the first date on which the shares of Common Stock trade regular way on the principal securities market on which the shares of Common Stock are then traded without the right to receive such distribution. 
  

 79 

 (c) Whenever the Notes shall become convertible pursuant to this Section 15.01, the Company or, at
the Company’s request, the Trustee in the name and at the expense of the Company, shall notify the holders of the event triggering such convertibility in the manner provided in Section 16.03, and the Company shall also publicly announce
such information and publish it on the Company’s web site. Any notice so given shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. 
 (d) A Note in respect of which a holder has delivered a Repurchase Notice exercising such holder’s right to require the Company to repurchase such
Note pursuant to Section 3.05 or 3.06 may be converted only if such Repurchase Notice is withdrawn in accordance with Section 3.08 prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Repurchase Date or the
Fundamental Change Repurchase Date, as applicable. 
 (e) A holder of Notes is not entitled to any rights of a holder of Common Stock until
such holder has converted his Notes and received upon conversion thereof shares of Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article 15. 
 Section 15.02. Exercise of Conversion Right; No Adjustment for Interest or Dividends. In order to exercise the conversion right with
respect to any Note in certificated form, the Company must receive at the office or agency of the Company maintained for that purpose in the City of New York or, at the option of such holder, the Corporate Trust Office, such Note with the original
or facsimile of the form entitled “Conversion Notice” on the reverse thereof, duly completed and manually signed, together with such Notes duly endorsed for transfer, accompanied by the funds, if any, required by this
Section 15.02. Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued, and shall be accompanied
by transfer or similar taxes, if required pursuant to Section 15.07. 
 In order to exercise the conversion right with respect to any
interest in a Global Note, the beneficial holder must complete, or cause to be completed, the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program; deliver, or cause to be delivered, by
book-entry delivery an interest in such Global Note; furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or conversion agent; and pay the funds, if any, required by this Section 15.02 and any
transfer taxes if required pursuant to Section 15.07. 
 If the Company is required to issue shares of Common Stock upon settlement in
accordance with Section 15.12, as promptly as practicable after satisfaction of the requirements for conversion set forth above, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name
other than that of the Noteholder (as if such transfer were a transfer of the Note or Notes (or portion 

  

 80 

 
thereof) so converted), and in accordance with the time periods set forth herein, the Company shall issue and shall deliver to such Noteholder at the office
or agency maintained by the Company for such purpose pursuant to Section 6.02, a certificate or certificates for the number of full shares of Common Stock (if any) issuable upon the conversion of such Note or portion thereof as determined by
the Company in accordance with the provisions of Section 15.12 (or in the case of Notes submitted for conversion in connection with a Fundamental Change pursuant to Section 15.01(a)(iii)) on or after the record date for receiving
distributions in connection with the Fundamental Change, or if earlier, the Effective Date, the Conversion Value pursuant to Section 15.12 shall be determined based on the kind and amount of cash, securities and other assets or property that a
holder of a number of shares of Common Stock equal to the Conversion Rate would have owned or been entitled to receive in such transaction; and provided further that (i) if the determination date is the record date, the holder shall
receive the Conversion Value on the Effective Date, (ii) in the case of Notes submitted for conversion in connection with a Fundamental Change pursuant to Section 15.01(a)(iii), if the Make Whole Amount is payable pursuant to
Section 15.13, cash in respect of any accrued but unpaid interest to, but excluding, the Conversion Date, payable on the date the other consideration due is payable and (iii) a check or cash in respect of any fractional interest in respect
of a share of Common Stock arising upon such conversion, calculated by the Company as provided in Section 15.03. The cash, and, if applicable, a certificate or certificates for the number of full shares of Common Stock into which the Notes are
converted (and cash in lieu of fractional shares) will be delivered to a converting holder after satisfaction of the requirements for conversion set forth above, in accordance with Section 15.12. 
 Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in
this Section 15.02 have been satisfied as to such Note (or portion thereof) or, if later, the Determination Date (the “Conversion Date”), and the Person in whose name any certificate or certificates for shares of Common Stock
shall be issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; provided that any such surrender on any date when the stock transfer books of the Company shall be
closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion
Rate in effect on the Conversion Date. 
 Any Note or portion thereof surrendered for conversion during the period from 5:00 p.m., New York
City time, on the Record Date for any interest payment date to 5:00 p.m., New York City time, on the Business Day preceding the applicable interest payment date shall be accompanied by payment, in immediately available funds or other funds
acceptable to the Company, of an amount equal to the interest otherwise payable on such interest payment date on the principal amount being converted; provided that no such payment need be made (1) if a holder converts its Notes in
connection with a 

  

 81 

 
redemption and the Company has specified a redemption date that is after a Record Date and on or prior to the corresponding interest payment date,
(2) if a holder converts its Notes in connection with a Fundamental Change and the Company has specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the corresponding interest payment date or (3) to
the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. Except as otherwise provided above in this Article 15, no payment or other adjustment shall be made for interest accrued on any
Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article 15. If a holder exercises its conversion right pursuant to Section 15.01(a)(iii) and the Make Whole Amount is payable pursuant to
Section 15.13, such holder shall be entitled to accrued and unpaid interest on the converted Notes to, but excluding, the Conversion Date, which interest shall be payable in cash. In addition, notwithstanding the foregoing, in the case of Notes
submitted for conversion in connection with a Fundamental Change, such Notes shall continue to represent the right to receive the Make Whole Amount, if any, payable pursuant to Section 15.13, until such Make Whole Amount is so paid. 

Upon the conversion of an interest in a Global Note, the Trustee (or other conversion agent appointed by the Company), or the Custodian at the
direction of the Trustee (or other conversion agent appointed by the Company), shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversions of Notes effected through any conversion agent other than the Trustee. 
 Except with respect to a conversion of a Note in
connection with a Fundamental Change pursuant to which a Make Whole Amount will be payable, upon the conversion of a Note, the accrued but unpaid interest and accrued Tax Original Issue Discount attributable to the period from the issue date of the
Note to the Conversion Date, with respect to the converted Note, shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the holder thereof through delivery of cash and, if applicable, shares of Common
Stock (together with the cash payment, if any in lieu of fractional shares) in exchange for the Note being converted pursuant to the provisions hereof; and the cash and Fair Market Value of any shares of Common Stock (together with any such cash
payment in lieu of fractional shares) shall be treated as delivered, to the extent thereof, first in exchange for and in satisfaction of our obligation to pay the principal amount of the converted Note, the accrued but unpaid interest, and accrued
Tax Original Issue Discount through the Conversion Date from the issue date, and the balance, if any, the cash and the Fair Market Value of any Common Stock (and any such cash payment) shall be treated as issued in exchange for and in satisfaction
of the right to convert the Note being converted pursuant to the provisions hereof. 
 In case any Note of a denomination greater than $1,000
shall be surrendered for partial conversion, and subject to Section 2.04, the Company shall execute and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without 

  

 82 

 
charge to the holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered
Note. 
 Section 15.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip certificates
representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be issuable upon conversion shall be computed on
the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of any Note or Notes, the Company shall
make an adjustment and payment therefor in cash to the holder of Notes at a price equal to the Closing Sale Price on the last Trading Day immediately preceding the Conversion Date. 
 Section 15.04. Conversion Rate. The initial Conversion Rate for the Notes is 16.7771 shares of Common Stock per each $1,000 principal amount of
the Notes (herein called the “Conversion Rate”), subject to adjustment as provided in Section 15.05. 
 Section 15.05.
Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: 
 (a) In case the
Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the
Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction, 
 (i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed
for the determination of stockholders entitled to receive such dividend or other distribution plus the total number of shares of Common Stock constituting such dividend or other distribution; and 
 (ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for
such determination, 
 such increase to become effective immediately after the opening of business on the day following the date fixed for such
determination. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares
of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 15.05(a) is declared but not 

  

 83 

 
so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not
been declared. 
 (b) In case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling
them (for a period expiring within forty-five calendar days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a price per share less than the
Closing Sale Price on the Business Day immediately preceding the date of announcement of such issuance of such rights or warrants, 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 date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction, 
 (i) the numerator of which shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the total number of additional
shares of Common Stock offered for subscription or purchase, and 
 (ii) the denominator of which shall be the sum of the
number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the number of shares that the aggregate offering price of the total number of
shares so offered would purchase at such Current Market Price. 
 Such adjustment shall be successively made whenever any such rights or
warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants; provided, that no adjustment to the
Conversion Rate shall be made if the holder will otherwise participate in such distribution without conversion as a result of holding the Notes. To the extent that shares of Common Stock are not delivered after the expiration of such rights or
warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common
Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive
such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price
of such shares of Common Stock, there shall be taken into account any consideration received by the 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. 
  

 84 

 (c) In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of
Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case the outstanding shares of Common Stock
shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or
reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 
 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of Common Stock shares of any class of capital stock of the Company or
evidences of its indebtedness or assets (including securities, but excluding (i) any dividends or distributions referred to in Section 15.05(a), (ii) any rights or warrants referred to in Section 15.05(b), (iii) any
dividends or distributions paid exclusively in cash, or (iv) any dividends or distributions in connection with a reclassification, consolidation, merger, binding share exchange or sale to which Section 15.06 applies (any of the foregoing
hereinafter in this Section 15.05(d)) called the “Securities”)), then, in each such case (unless the Company elects to reserve such Securities for distribution to the Noteholders upon the conversion of the Notes so that any
such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such Securities which such holder would have received if such holder had converted its
Notes into Common Stock immediately prior to the record date) the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the record date with respect to such
distribution by a fraction, 
 (i) the numerator of which shall be the Current Market Price on such Record Date; and

 (ii) the denominator of which shall be the Current Market Price on such record date less the Fair Market Value (as
determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) on the record date of the portion of the Securities so distributed applicable to one share of Common Stock,

 such adjustment to become effective immediately prior to the opening of business on the day following such record date; provided that if the then
Fair Market Value (as so determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the record date, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Noteholder shall have the right to receive upon conversion the amount of Securities such holder would have received had such holder converted each Note on the record date. If 

  

 85 

 
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 Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 15.05(d) 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 on the applicable record date. 
 If the dividend or distribution requiring an adjustment pursuant to this clause (d) consists of capital stock of any class or series, or similar equity interests, of a Subsidiary or other business unit of the
Company, for purposes of making such adjustment, (i) the Current Market Price shall be based on the average of the Closing Sale Prices of such securities for the ten Trading Days 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 national or regional exchange or market on which such securities are then listed or quoted, and (ii) the Fair Market Value of
such securities shall be determined as provided herein, measured for the same period. 
 Rights or warrants distributed by the Company to all
holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or
events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to
have been distributed for purposes of this Section 15.05 (and no adjustment to the Conversion Rate under this Section 15.05 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 15.05(d). If any such right or warrant, including any such existing rights or warrants distributed prior
to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and
each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders
thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of
calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 15.05 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any
holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or
repurchase price received by a holder or holders of Common Stock with 

  

 86 

 
respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such
redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been
issued. 
 No adjustment of the Conversion Rate shall be made pursuant to this Section 15.05(d) in respect of rights or warrants
distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Company for distribution to holders of Notes upon conversion by such holders of Notes to Common Stock.

 For purposes of this Section 15.05(d) and Section 15.05(a) and (b), any dividend or distribution to which this
Section 15.05(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of
indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 15.05(d) with respect to such dividend or distribution shall then be made)
immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 15.05(a) and 15.05(b) with respect to such dividend or
distribution shall then be made), except (A) the record date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”,
“the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Section 15.05(a) and 15.05(b) and (B) any shares of
Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 15.05(a). 
 (e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (including any quarterly cash dividend, but
excluding (x) any quarterly cash dividend distributed on or after August 1, 2014, on the Common Stock to the extent the aggregate cash dividend per share of Common Stock in any Fiscal Quarter does not exceed the greater of (A) the
amount per share of Common Stock of the next preceding quarterly cash dividend on the Common Stock to the extent that such preceding quarterly dividend did not require any adjustment of the Conversion Rate pursuant to this Section 15.05(e) (as
adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 1.25% of the average of the Closing Sale Price of a share of Common Stock over the ten consecutive Trading Days immediately preceding the date of declaration of such
dividend calculated at the time of the declaration of each distribution during such quarter, (y) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, and
(z) any dividend or distribution in connection with a reclassification, consolidation, merger, 

  

 87 

 
binding share exchange or sale to which Section 15.06 applies), then, in such case, the Conversion Rate shall be increased so that the same shall equal
the rate determined by multiplying the Conversion Rate in effect on the applicable record date by a fraction, 
 (i) the
numerator of which shall be the Current Market Price on such record date; and 
 (ii) the denominator of which shall be the
Current Market Price on such record date less (x) the amount of the excess distribution in the case of a quarterly dividend on or after August 1, 2014, or (y) the full amount of cash so distributed (and not excluded as provided above)
in all other cases, in each of (x) and (y), as applicable to one share of Common Stock, 
 such adjustment to be effective immediately prior to the
opening of business on the day following the record date; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the record date, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion the amount of cash such holder would have received had such holder converted each Note on the record date. If 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 any adjustment is required to be made as
set forth in this Section 15.05(e) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the quarterly cash dividend permitted to be excluded
pursuant hereto. If an adjustment is required to be made as set forth in this Section 15.05(e) above as a result of a distribution that is not a quarterly dividend, such adjustment shall be based upon the full amount of the distribution.

 Notwithstanding the foregoing, adjustments to the Conversion Rate resulting from any quarterly cash dividends may not cause the Conversion
Rate (as adjusted for any other adjustment in this Section 15.05) to exceed 21.8103 per $1,000 principal amount of Notes. 
 (f) In
case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of
consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the
“Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding 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 Expiration Time by a fraction, 
  

 88 

 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined
as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged 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 (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, and 
 (ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time multiplied by the Closing Sale Price of a share of Common Stock on the Trading Day
next succeeding the Expiration Time, 
 such adjustment to become effective immediately prior to the opening of business on the day following the Expiration
Time. If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate
shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. 
 (g) For
purposes of this Section 15.05, the following terms shall have the meaning indicated: 
 (i) “Current Market
Price” shall mean the average of the daily Closing Sale Prices per share of Common Stock over the ten consecutive Trading Days ending on the earlier of such date of determination and the day before the “ex” date with
respect to the issuance, distribution, subdivision or combination requiring such computation. For purpose of this paragraph, the term “ex” date, (1) when used 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 Sale Price was obtained without the right to receive such issuance or distribution, and (2) when used 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. 
 If another issuance, distribution, subdivision or combination to which Section 15.05 applies occurs during the period applicable for
calculating “Current Market Price” pursuant to the definition in the preceding paragraph, “Current Market Price” shall be calculated for such period in a manner determined by the Board of Directors to reflect the
impact of such issuance, 

  

 89 

 
distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such period. 
 (ii) “Fair Market Value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s-length
transaction. 
 (iii) “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 for or converted into any combination of cash,
securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
 (h) The Company may make such increases in the Conversion Rate, in addition to those required by Section 15.05(a)-(f) as the Board of Directors
considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for
income tax purposes. 
 To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any
amount for any period of time if the period is at least twenty (20) Business Days, the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the
Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes a notice of the increase, and such notice shall state the
increased Conversion Rate and the period during which it will be in effect. 
 (i) No adjustment in the Conversion Rate shall be required
unless such adjustment would require an increase or decrease of at least one percent (1%) in such rate; provided that any adjustments that by reason of this Section 15.05(i) are not required to be made shall be carried forward and
the Company shall make such carry forward adjustments, regardless of whether the aggregate adjustment is less than 1%, within one year of the first such adjustment carry forward, upon redemption, upon a Fundamental Change or at maturity. All
calculations under this Article 15 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock
pursuant to a Company plan for reinvestment of dividends or interest or for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities. To the extent the Notes
become convertible into cash, assets, property or securities (other than capital stock of the Company), no adjustment need be made thereafter as to the cash, 

  

 90 

 
assets, property or such securities. Interest will not accrue on any cash into which the Notes are convertible. 
 (j) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any conversion agent other than the
Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such
Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such
certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the
Conversion Rate to the holder of each Note at his last address appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty (20) calendar days after execution thereof. Failure to deliver such notice shall
not affect the legality or validity of any such adjustment. 
 (k) In any case in which this Section 15.05 provides that an adjustment
shall become effective immediately after (1) a record date for an event, (2) the date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 15.05(a), (3) a date fixed for
the determination of stockholders entitled to receive rights or warrants pursuant to Section 15.05(b), or (4) the Expiration Time for any tender or exchange offer pursuant to Section 15.05(f), (each, an “Adjustment
Determination Date”), the Company may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Note converted after such Adjustment Determination Date and before
the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the cash and, if applicable, Common Stock
issuable upon such conversion before giving effect to such adjustment and (y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.03. For purposes of this Section 15.05(k), the term
“Adjustment Event” shall mean: 
 (i) in any case referred to in clause (1) hereof, the occurrence of
such event, 
 (ii) in any case referred to in clause (2) hereof, the date any such dividend or distribution is paid or
made, 
 (iii) in any case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and

  

 91 

 (iv) in any case referred to in clause (4) hereof, the date a sale or exchange of
Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable. 
 (l) For purposes of this
Section 15.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. 
 (m) No adjustment to the Conversion Rate shall be made pursuant to this Section 15.05 if the holders of the Notes may participate in the transaction that would otherwise give rise to adjustment pursuant to this Section 15.05.

 Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. 
 (a) If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a
subdivision or combination to which Section 15.05(c) applies), (ii) any consolidation, merger, binding share exchange or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to
receive capital stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of all or substantially all of the properties and assets of the Company
to any other Person as a result of which holders of Common Stock shall be entitled to receive capital stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the
successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing for the
conversion and settlement of Notes as set forth in this Indenture. 
 (b) Notwithstanding the provisions of Section 15.12, and subject
to the provisions of Section 15.01 and 15.02, the Conversion Value with respect to each $1,000 principal amount of Notes tendered for conversion on or after the second Trading Day immediately preceding the effective date of any such transaction
shall be calculated (as provided in (d) below) based on the kind and amount of shares of capital stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, binding
share exchange, combination, sale or conveyance by a holder of Common Stock holding, immediately prior to the transaction, a number of shares of Common Stock equal to the Conversion Rate (plus Additional Shares, to the extent that the holder is
entitled to Additional Shares in accordance with Section 15.13 upon conversion) immediately prior to such transaction (the “Exchange Property”) assuming such holder of Common Stock did not exercise his rights of election, if
any, as to the kind or amount of capital stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, 

  

 92 

 
consolidation, merger, binding share exchange, combination, sale or conveyance (provided that, if the kind or amount of capital stock, other
securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, binding share exchange, combination, sale or conveyance is not the same for each share of Common Stock in respect of which
such rights of election shall not have been exercised (“non-electing share”), then for the purposes of this Section 15.06 the kind and amount of stock, other securities or other property or assets (including cash) receivable
upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non-electing share shall be determined based on the weighted average of the types and amounts of consideration received by the holders of Common
Stock that affirmatively made such an election). 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 15. 
 (c) The Conversion Value in respect of any Notes tendered for conversion on or after the second Trading Day immediately preceding the effective date of
any such transaction shall be equal to the average of the daily values of the Exchange Property pertaining to such Notes as determined in the next sentence (the “Exchange Property Value”) for each of the ten consecutive Trading Days
(appropriately adjusted to take into account the occurrence during such period of stock splits and similar events) beginning on the later of (A) the second Trading Day immediately following the day the Notes are tendered for conversion and
(B) the effective date of such transaction (the “Exchange Property Weighted Average Price”). For the purpose of determining the value of any Exchange Property: 
 (i) Any shares of common stock of the successor or purchasing corporation or any other corporation that are included in the Exchange
Property shall be valued as set forth in Section 15.12 as if such shares were “Common Stock” using the procedures set forth in the definition of “Closing Sale Price” in Section 1.01; and 
 (ii) Any other property (other than cash) included in the Exchange Property shall be valued in good faith by the Board of Directors or by
a New York Stock Exchange member firm selected by the Board of Directors. 
 (d) The Company shall deliver such Conversion Value to holders
of Notes so converted as follows: 
 (i) An amount equal to the Principal Return, determined as set forth in
Section 15.12(b)(i); and 
 (ii) If the Conversion Value of the Notes so converted is greater than the Principal Return,
an amount of Exchange Property, determined as set forth in the next succeeding paragraph, equal to such aggregate Conversion Value less the Principal Return (the “Net Exchange Property Amount”). 
  

 93 

 The amount of Exchange Property to be delivered shall be determined by dividing the Net Exchange Property
Amount by the Exchange Property Weighted Average Price. If the Exchange Property includes more than one kind of property, the amount of Exchange Property of each kind to be delivered shall be in the proportion that the Exchange Property Value of
such kind of Exchange Property bears to the Exchange Property Value of all the Exchange Property. If the foregoing calculations would require the Company to deliver a fractional share or unit of Exchange Property to a holder of Notes being
converted, the Company shall deliver cash in lieu of such fractional share or unit based on its Exchange Property Weighted Average Price. 
 (e) Notwithstanding clauses (b), (c) and (d) above, if the Notes are tendered for conversion prior to the effective date of any such transaction pursuant to Section 15.01(a)(iii) above, and the Principal Return and Net Share
Amount, if any, have been determined, but have not been delivered prior to the effective date of such transaction, then the Company shall (i) pay the Principal Return in cash and (ii) instead of delivering the Net Share Amount, if
applicable, deliver an amount of Exchange Property that a holder of Common Stock holding, immediately prior to the transaction, a number of shares of Common Stock equal to the Net Share Amount, would receive, assuming such holder of Common Stock did
not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount
of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance is not the same for each non–electing share, then for the purposes of this Section 15.06 the kind
and amount of securities, cash or other property receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non–electing share shall be determined based on the weighted average of the types
and amounts of consideration received by the holders of Common Stock that affirmatively made such an election). If the foregoing calculations would require the Company to deliver a fractional share or unit of Exchange Property to a holder of Notes
being converted, the Company shall deliver cash in lieu of such fractional share or unit based on the Exchange Property Value (as so determined). 
 (f) Notwithstanding clauses (b), (c), (d) and (e) above, if Notes are tendered for conversion at a time when neither of the ten day weighted averaging periods contemplated in clause (c) or clause (e) applies in full to
the determination of the Conversion Value, then the Conversion Value and the amount of cash and Exchange Property comprising the Principal Return and the Net Share Amount will be determined proportionally, with the weighted average amount relating
to the portion of the ten day period falling prior to the effective date being valued as contemplated by clause (e) and with the weighted average amount relating to the portion of that period falling on or after the effective date being valued
as contemplated by clause (c). 
  

 94 

 (g) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each
holder of Notes, at its address appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty (20) calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture. 
 (h) The above provisions of this Section shall similarly apply to successive reclassifications,
changes, consolidations, mergers, combinations, sales and conveyances. 
 (i) If this Section 15.06 applies to any event or occurrence,
Section 15.05 shall not apply. 
 Section 15.07. Taxes on Shares Issued. The issue of stock certificates, if any, on
conversion of Notes shall be made without charge to the converting Noteholder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required to pay any such tax which may be
payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the
Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
 Section 15.08. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. The Company
shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes as required by this Indenture from time to time as such
Notes are presented for conversion. 
 Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount
that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable, if any, upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel,
be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 
 The
Company covenants that all shares of Common Stock which may be issued upon conversion of Notes will upon issue be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or
approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then permitted by the rules and
interpretations of the Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 
  

 95 

 The Company further covenants that, if at any time the Common Stock shall be listed on The New York Stock
Exchange or any other national securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on
such exchange or automated quotation system, all Common Stock issuable upon conversion of the Notes; provided that if the rules of such exchange or automated quotation system permit the Company to defer the listing of such Common Stock until
the first conversion of the Notes in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such exchange or automated quotation
system at such time. 
 Section 15.09. Responsibility of Trustee. The Trustee and any other conversion agent shall not at any time be
under any duty or responsibility to any holder of Notes to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such
adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other conversion agent shall not be accountable with respect to the validity or
value (or the kind or amount) of any shares of Common Stock, or of any capital stock, other securities or other assets or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other
conversion agent make no representations with respect thereto. Neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 15. Without limiting the generality of the
foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.06 relating either to the kind
or amount of shares of capital stock or other securities or other assets or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.06 or to any adjustment to be made
with respect thereto, but, subject to the provisions of Section 9.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall
be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the accuracy of the
method employed in calculating the Trading Price or whether any facts exist which may require any adjustment of the Trading Price. 
  

 96 

 Section 15.10. Notice to Holders Prior to Certain Actions. In case: 
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant
to Section 15.05; or 
 (b) the Company shall authorize the granting to the holders of all or substantially all of its Common Stock of
rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or 
 (c) of any reclassification or
reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or
merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 
 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company, 
 the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his address appearing on the Note Register provided for in Section 2.05 of this Indenture, as promptly as possible
but in any event at least ten calendar days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record
is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution,
reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. 
 Section 15.11. Stockholder Rights
Plans. If the rights provided for in the Company’s stockholder rights agreement dated June 24, 2002 or in any future rights plan adopted by the Company have separated from the shares of Common Stock in accordance with the provisions of
the applicable stockholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Notes, if any, the Conversion Rate will be adjusted as provided in
Section 15.05(d). 
  

 97 

 Section 15.12. Settlement Upon Conversion. 
 (a) (i) Upon conversion of any Note, subject to Sections 15.01, 15.02, 15.06 and this Section 15.12, the Company shall satisfy its obligation upon
conversion (the “Conversion Obligation”) by payment and delivery of cash and, if applicable as provided herein, shares of Common Stock, the aggregate value of which (the “Conversion Value”) shall be equal to the sum
of the Daily Settlement Amounts for each of the 10 Trading Days during the Related Observation Period. 
 (ii)
“Observation Period “ with respect to any Note means the ten consecutive Trading-Day period beginning on and including the second Trading Day immediately following the Conversion Date. 
 (iii) The “Daily Settlement Amounts,” for any Trading Day in Observation Period, shall equal one-tenth (1/10) of the
product of (x) the applicable Conversion Rate on such Trading Day; and (y) the Volume Weighted Average Price per share of the Common Stock on such Trading Days (appropriately adjusted to take into account the occurrence during such period
of stock splits and similar events). The “Volume Weighted Average Price” per share of the Common Stock on any Trading Day will be the volume weighted average price on the New York Stock Exchange or, if the Common Stock is not listed
on the New York Stock Exchange, on the principal U.S. securities exchange or over-the-counter market on which the Common Stock is then listed or traded, from 9:30 a.m. to 4:00 p.m. (New York City time) on that Trading Day as displayed by Bloomberg
(Bloomberg key strokes: EYE Equity VAP) (or if such volume weighted average price is not available, the market value of one share on such Trading Day as the Board of Directors determine in good faith using a volume weighted method). 
 (b) The Company shall deliver the Conversion Value of the Notes surrendered for conversion to converting holders as follows: 
 (i) an amount in cash (the “Principal Return”) equal to the lesser of (A) the aggregate Conversion Value of the
Notes to be converted and (B) the aggregate principal amount of the Notes to be converted; 
 (ii) if the aggregate
Conversion Value of the Notes to be converted is greater than the Principal Return, an amount in whole shares of Common Stock (the “Net Shares”), determined pursuant to Section 15.12(c), equal to such aggregate Conversion Value
less the Principal Return (the “Net Share Amount”); and 
 (iii) an amount in cash in lieu of any fractional
shares of Common Stock. 
  

 98 

 (c) The number of Net Shares to be paid will be equal to the sum of the Daily Net Share amount for each
day of the Observation Period. The “Daily Net Share Amount” shall be equal to one-tenth (1/10) of the Net Share Amount divided by the Volume Weighted Average Price on such Trading Day. Any cash payment for fractional shares
also will be based on the Daily Net Share Amounts. 
 (d) The Conversion Value, Principal Return, Net Share Amount and the number of Net
Shares will be determined by the Company at the end of the ten consecutive trading period beginning on the second Trading Day immediately following the day the Notes are tendered for conversion (the “Determination Date”);
provided that with respect to any Notes surrendered for conversion pursuant to Section 15.01(a)(iii), the Determination Date shall be the last Trading Day in the period on which the applicable Stock Price is determined (pursuant to the
definition thereof) in connection with the determination of Additional Shares, if any, to be added to the Conversion Rate. 
 (e) Payment of
the cash and Net Share Amount, if any, in satisfaction of the Conversion Obligation shall be made by the Company promptly following the Determination Date, but in no event later than three Business Days thereafter (the “Conversion Settlement
Date”) by paying in cash the Principal Return (together with any cash in lieu of fractional shares) to the holder of a Note surrendered for conversion, or such holder’s nominee or nominees, and issue, or cause to be issued, and deliver
to the Conversion Agent or to such holder, or such holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock equal to the Net Share Amount, if any, to which such
holder shall be entitled as part of such Conversion Obligation. 
 Section 15.13. Fundamental Change Make Whole Amount. 
 (a) Subject to the provisions hereof, if a Noteholder elects to convert its Notes pursuant to Section 15.01(a)(iii) following the occurrence of a
Fundamental Change that occurs on or prior to August 1, 2014, the Company will increase the applicable Conversion Rate for the Notes so surrendered for conversion at any time during the period that is 15 calendar days prior to the date
announced by the Company as the anticipated effective date for the Fundamental Change and until and including the date that is 15 calendar days after the Effective Date such that the Holder will be entitled to receive, in addition to the cash and
Common Stock, if applicable, it is entitled to receive pursuant to Section 15.12, a number of shares of Common Stock as set forth in Section 15.13(b) (the “Make Whole Amount”). 
 (b) The number of Additional Shares will be determined by reference to the table in paragraph (e) below and is based on the date on which the
Fundamental Change becomes effective (the “Effective Date”) and the price paid per share of the Common Stock in the Fundamental Change transaction (the “Stock Price”). If holders of the Common Stock receive only
cash in the Fundamental Change Transaction, the Stock Price will equal the cash amount paid per share. In all other cases, the Stock Price will 

  

 99 

 
equal and the average of the Closing Sale Price of the Common Stock over the ten Trading Day period ending on the Trading Day immediately preceding the
Effective Date. 
 (c) The Stock Prices set forth in the first row of the table below shall be adjusted as of any date on which the
Conversion Rate of the Notes is adjusted pursuant to Section 15.13 (and other than any increase to the Conversion Rate for a Fundamental Change as set forth in this Section 15.13). The adjusted Stock Prices will equal the Stock Prices
applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and (ii) the denominator of which is
the Conversion Rate as so adjusted. 
 (d) The number of Additional Shares will be adjusted in the same manner and for the same events as the
Conversion Rate is adjusted pursuant to Section 15.05. 
 (e) The following table sets forth the Stock Price and number of Additional
Shares issuable per $1,000 principal amount of Notes:

 (f) If the exact Stock Price and Effective Date are not set forth on the table above, then:

 (i) If the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates
in the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day
year. 
 (ii) If the Stock Price is in excess of $125.00 per share, subject to adjustment, the Company shall not increase the
Conversion Rate by any Additional Shares. 
  

 100 

 (iii) If the Stock Price is less than $45.85 per share, subject to adjustment, the
Company shall not increase the Conversion Rate by any Additional Shares. 
 (g) Notwithstanding the foregoing, in no event will the total
number of shares of Common Stock issuable upon conversion of a Note (after giving effect to the make-whole adjustment required by this Section 15.13) exceed 21.8103 per $1,000 principal amount of Notes, subject to adjustment in the same
manner and for the same events as the Conversion Rate may be adjusted pursuant to Section 15.05. 
 (h) Settlement of Notes converted
upon Fundamental Change shall be as set forth in Section 15.06. If the Company is required to increase the Conversion Rate by Additional Shares of Common Stock as a result of the Fundamental Change: 
 (i) If the last day of the applicable Observation Period related to Notes surrendered for conversion is prior to the third Trading Day
preceding the Effective Date of the Fundamental Change, the Company will settle such conversion as set forth in Section 15.12 by delivering the amount of cash and shares of Common Stock, if any, based on the applicable Conversion Rate then in
effect without regard to the number of Additional Shares of Common Stock to be added to the Conversion Rate, on the third Trading Day immediately following the last day of the applicable Observation Period. In addition, as soon as practicable
following the Effective Date of the Fundamental Change, the Company will deliver the increase in such amount of cash and Exchange Property deliverable in lieu of shares of Common Stock, if any, as if the Conversion Rate had been increased by such
number of Additional Shares of Common Stock during the relevant Observation Period and based upon the related Volume Weighted Average Prices during such Observation Period. If such increased amount results in an increase to the amount of cash to be
paid to holders of the Notes, the Company will pay such increase in cash, and if such increased settlement amount results in an increase to the number of shares of Common Stock, the Company will deliver such increase by delivering the Exchange
Property based on such increased number of shares of Common Stock; and 
 (ii) If the last day of the applicable Observation
Period related to Notes surrendered for conversion is on or following the third scheduled Trading Day preceding the effective date of the Fundamental Change, the Company will settle such conversion in accordance with Section 15.12 based on the
Conversion Rate as increased by the additional shares of Common Stock on the later to occur of (x) the Effective Date of the transaction and (y) the third Trading Day immediately following the last day of the applicable Observation Period.

 FORM OF REVERSE OF NOTE 
 ADVANCED MEDICAL OPTICS, INC. 
 3.25% CONVERTIBLE SENIOR SUBORDINATED NOTE DUE 2026 
 This note is one of a duly authorized issue of notes of the Company, designated as its 3.25% Convertible Senior Subordinated Notes due 2026 (herein
called the “Notes”), limited in aggregate principal amount to $500,000,000, issued and to be issued under and pursuant to an Indenture dated as of June 13, 2006, (herein called the “Indenture”), between the Company and U.S.
Bank National Association, as trustee (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the Notes. Defined terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture. 
 If an Event of Default occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be declared to be
due and payable by either the Trustee or the holders of at least 25% in aggregate principal amount of the Notes then outstanding, and, upon said declaration the same shall be due and payable, (a) immediately if there shall no longer be a Senior
Credit Facility or (b) if the Senior Credit Facility is in effect, immediately upon the earlier to occur of (i) the date indebtedness under the Senior Credit Facility is declared accelerated and (ii) the fifth Business Day after
written notice of the declaration of such acceleration has been given to the agents under the Senior Credit Facility, in the manner, with the effect and subject to the conditions provided in the Indenture. 
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of a majority in aggregate principal amount of
the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of
the holders of the Notes, subject to exceptions set forth in Section 11.02 of the Indenture. Subject to the provisions of the Indenture, the holders of a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf
of the holders of all of the Notes, waive any past default or Event of Default, subject to exceptions set forth in the Indenture. Upon any such waiver, said default shall for all purposes of this Note and the Indenture be deemed to have been cured
and to be not continuing, but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
 The
indebtedness evidenced by the Notes is, to the extent and in the manner provided in the Indenture, contractually subordinated in right of payment or satisfaction to the prior payment or satisfaction in full in cash of all Senior Indebtedness of the
Company, whether outstanding at the date of the Indenture or thereafter incurred, and this 

  

 A-7 

 
Note is issued subject to the provisions of the Indenture with respect to such subordination. Each holder of this Note, by accepting the same, agrees to and
shall be bound by such provisions and authorizes the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and appoints the Trustee his attorney-in-fact for such purpose. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Company and the holder of the Notes,
the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture
prescribed. 
 Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 
 The Notes are issuable in fully registered form, without coupons, in denominations of $1,000 principal amount and any multiple of $1,000. At the office
or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment or other
governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations. 
 At any time on or after August 4, 2014 and prior to maturity, the Notes may be redeemed at the option of the Company, in whole or in part, upon
mailing a notice of such redemption not less than 30 calendar days but not more than 60 calendar days before the redemption date to each holder of Notes, all as provided in the Indenture, in cash at a redemption price equal to 100% of the principal
amount of Notes being redeemed and accrued and unpaid interest to, but excluding, the redemption date; provided that if the redemption date is after a record date and on or prior to the corresponding interest payment date, the accrued and
unpaid interest shall be payable to the holder of record of this Note on the preceding January 15 or July 15, as the case may be. The Company may not redeem any Notes if a default in the payment of interest on the Notes has occurred and is
continuing. 
 The Notes are not subject to redemption through the operation of any sinking fund. 
 If a Fundamental Change occurs at any time prior to maturity of the Notes, this Note will be subject to a repurchase in cash, at the option of the
holder, on a Fundamental Change Repurchase Date, specified by the Company, that is not less than 20 Business Days nor more than 35 Business Days after notice thereof, at a repurchase price equal to 100% of the principal amount hereof, together with
accrued and unpaid interest on this Note to, but excluding, the Fundamental Change Repurchase Date, if any; provided that 

  

 A-8 

 
if such Fundamental Change Repurchase Date falls after a record date and on or prior the corresponding interest payment date, the accrued and unpaid interest
shall be payable to the holder of record of this Note on the preceding January 15 or July 15, as the case may be. The Notes submitted for repurchase must be $1,000 in principal amount or whole multiples thereof. The Company shall mail to
all holders of record of the Notes (and to beneficial owners as required by applicable law) a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the 10th Business Day after the
occurrence of such Fundamental Change. For a Note to be so redeemed at the option of the holder, the holder must deliver to the Paying Agent in accordance with the terms of the Indenture, the Repurchase Notice containing the information specified by
the Indenture, together with such Note, duly endorsed for transfer, or (if the Notes are Global Notes) book-entry transfer of the Note, prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change
Repurchase Date. 
 Subject to the terms and conditions of the Indenture, each holder shall have the right, at such holder’s option, to
require the Company to repurchase all or any portion of the Notes held by such holder, on August 1, 2014, August 1, 2017, and August 1, 2021, at a repurchase price in cash equal to 100% of the principal amount of this Note, together
with any accrued and unpaid interest on this Note to, but excluding, the Repurchase Date. The accrued and unpaid interest shall be payable to the holder of record of this Note on the preceding January 15 or July 15, as the case may be. To
exercise such right, a holder shall deliver to the Paying Agent the Repurchase Notice containing the information specified by the Indenture, together with the Note, duly endorsed for transfer, or (if the Notes are Global Notes) book-entry transfer
of the Note, at any time from 9:00 a.m., New York City time, on the date that is 20 Business Days prior to the applicable Repurchase Date to 5:00 p.m., New York City time, on the Business Day immediately preceding the applicable Repurchase Date.

 Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal at any time
prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date or the Repurchase Date, as applicable, all as provided in the Indenture. 
 If on the Fundamental Change Repurchase Date or the Repurchase Date the Paying Agent holds money sufficient to pay the repurchase price of the Notes that
holders have elected to require the Company to repurchase in accordance with the Indenture, then, on the Fundamental Change repurchase Date or the Repurchase Date, as the case may be, such Notes will cease to be outstanding, interest will cease to
accrue and all other rights of the holders of such Notes will terminate, other than the right to receive the repurchase price upon delivery or book entry transfer of the Note. This will be the case whether or not book entry transfer of the Note has
been made or the Notes has been delivered to the Paying Agent. 
  

 A-9 

 Subject to and in compliance with the provisions of the Indenture, on or prior to the Trading Day
immediately preceding July 1, 2014, the holder hereof has the right, at its option, to convert each $1,000 principal amount of this Note into cash or, as provided in the Indenture, cash and shares of Common Stock, equal to the conversion rate
of 16.7771 shares of Common Stock (a conversion price of approximately $59.61 per share), subject to adjustment from time to time as provided in the Indenture, upon surrender of this Note (if in certificated form) with the form entitled
“Conversion Notice” on the reverse hereof duly completed and manually signed, to the Company at the office or agency of the Company maintained for that purpose in the City of New York in accordance with the terms of the Indenture, or at
the option of such holder, the Corporate Trust Office, together with any funds required pursuant to the terms of the Indenture, and, unless the shares issuable on conversion, if any, are to be issued in the same name as this Note, duly endorsed by,
or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by such holder’s duly authorized attorney; provided, however, that at any time prior to the close of business on the
trading Day preceding July 1, 2014, holders may convert their Notes only upon the occurrence of specified events set forth in the Indenture. The Company will notify the holder thereof of any event triggering the right to convert the Notes prior
to July 1, 2014, as specified above in accordance with the Indenture. In order to exercise the conversion right with respect to any interest in a Global Note, the holder must complete the appropriate instruction form pursuant to the
Depositary’s book-entry conversion program, deliver by book-entry delivery an interest in such Global Note, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or conversion agent, and pay the
funds, if any, required pursuant to the terms of the Indenture. 
 In the event the holder surrenders this Note for conversion in connection
with a Fundamental Change occurring prior to August 1, 2014, the Company will increase the applicable Conversion Rate by the Make Whole Amount as and when provided in the Indenture. 
 No adjustment in respect of interest on any Note converted or dividends on any shares issued upon conversion of such Note will be made upon any
conversion except as set forth in the next sentence. If this Note (or portion hereof) is surrendered for conversion during the period from the 5:00 p.m., New York City time, on any applicable Record Date for the payment of interest to 5:00 p.m., New
York City time, on the Business Day preceding the corresponding interest payment date, this Note (or portion hereof being converted) must be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an
amount equal to the interest otherwise payable on such interest payment date on the principal amount being converted; provided that no such payment shall be required (1) if the holder surrenders this Note for conversion in connection
with a redemption and the Company has specified a Redemption Date that is after a Record Date and on or prior to the corresponding interest payment date, (2) if the holder surrenders this Note in connection with a Fundamental Change and the
Company has specified a Fundamental Change Repurchase 

  

 A-10 

 
Date that is after a Record Date and on or prior to the corresponding interest payment date or (3) to the extent of any overdue interest, if any exists
at the time of conversion with respect to this Note. Notwithstanding the foregoing, in the case of Notes submitted for conversion in connection with a Fundamental Change as set forth in the Indenture, such Notes shall continue to represent the right
to receive the Make Whole Amount, if any, payable pursuant to the Indenture until such Make Whole Amount is so paid. 
 No fractional shares
will be issued upon any conversion, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion.

 A Note in respect of which a holder is exercising its right to require repurchase may be converted only if such holder validly withdraws
its election to exercise such right to require repurchase in accordance with the terms of the Indenture. 
 Any Notes called for redemption,
unless surrendered for conversion by the holders thereof on or before 5:00 p.m., New York City time, on the Trading Day preceding the Redemption Date, may be deemed, to the fullest extent required by law, to be redeemed from the holders of such
Notes for an amount equal to the applicable redemption price, together with accrued but unpaid interest to, but excluding, the date fixed for redemption, by one or more investment banks or other purchasers who may agree with the Company (i) to
purchase such Notes from the holders thereof and convert them into cash and, if applicable, shares of Common Stock, and (ii) to make payment for such Notes as aforesaid to the Trustee in trust for the holders. 
 Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer
set forth in the Indenture, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal
amount and bearing such restrictive legends as may be required by this Indenture. No service charge shall be made to any holder for any registration of, transfer or exchange of Notes, but the Company may require payment by the holder of a sum
sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes. 
 The Company, the Trustee, any Paying Agent, any conversion agent and any Note Registrar may deem the Person in whose name this Note shall be registered upon the Note Register to be, and may treat it as, the absolute
owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on
account of the principal of, premium, if any, and interest on this Note, for conversion of this Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any conversion agent nor 

  

 A-11 

 
any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be
valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any this Note. 
 No recourse for the payment of the principal of or any premium or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the
Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, member, manager, employee, agent, officer, director or subsidiary, as
such, past, present or future, of the Company or of any successor thereto, either directly or through the Company or any of the Company’s subsidiaries or of any successor thereto, whether by virtue of any constitution, statute or rule of law or
by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as consideration for, the execution of the Indenture and the issue of
this Note. 
 In addition to the rights provided to holders of Notes under the Indenture, holders shall have all the rights set forth in the
Registration Rights Agreement dated as of June 13, 2006, between the Company and the Initial Purchasers named therein (the “Registration Rights Agreement”).

Registration Statement shall be on Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by such Holders in accordance with the methods of distribution elected by the Holders and set forth in the

(180) calendar days after the Issue Date (the “Effectiveness Deadline Date”), and to keep the Initial Shelf Registration Statement (or any Subsequent Shelf Registration Statement) continuously effective under the

 (b) If the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during
the Effectiveness Period (other than because all Registrable Securities registered thereunder shall have been resold pursuant thereto or shall have otherwise ceased to be Registrable Securities), the Company shall use its reasonable best efforts to
obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within thirty (30) days of such cessation of effectiveness amend the Shelf Registration Statement in a manner reasonably expected to obtain
the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration Statement covering all of the securities that as of the date of such filing are Registrable Securities (a “Subsequent Shelf
Registration Statement”). If a Subsequent Shelf Registration Statement is filed, the Company shall use its reasonable best efforts to cause the Subsequent Shelf Registration Statement to become effective as promptly as is practicable after
such filing and to keep such Registration Statement (or subsequent Shelf Registration Statement) continuously effective until the end of the Effectiveness Period. 
 (c) The Company shall supplement and amend the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration
Statement, if required by the Securities Act or as necessary to name an Election Holder as a selling securityholder pursuant to Section 2(d) below. 
 (d) Each Holder agrees that if such Holder wishes to sell Registrable Securities pursuant to a Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(d) and
Section 3(i) of this Agreement. Following the date that the Initial Shelf Registration Statement is declared effective, each Holder that is not an Election Holder wishing to sell Registrable Securities pursuant to a Shelf Registration Statement
and related Prospectus agrees to deliver an Election and Questionnaire to the Company at least fifteen (15) Business Days prior to any intended distribution of Registrable Securities under the Shelf Registration Statement. From and after the
date the Initial Shelf Registration Statement is declared effective, the Company shall, as promptly as practicable after the date an Election and Questionnaire is delivered to the Company in accordance with the provisions of Section 8(d)8(d),
and in any event upon the later of (1) fifteen (15) Business Days after such date or (2) fifteen (15) Business Days after the expiration of any Deferral Period in effect when the Election and Questionnaire is delivered or put
into effect within fifteen (15) Business Days of such delivery date: 
 (i) if required by applicable law, file with the
Commission a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or
file any other required document so that the Holder delivering such Election and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver
such Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable best efforts to cause such post-effective
amendment to be declared effective under the 

  

 5 

 
Securities Act as promptly as is practicable, but in any event by the date (the “Amendment Effectiveness Deadline Date”) that is
forty-five (45) days after the date such post-effective amendment is required by this clause to be filed by the Company in accordance with this clause (i); 
 (ii) provide such Holder copies of any documents filed pursuant to Section 2(d)(i); and 
 (iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed
pursuant to Section 2(d)(i); 
 provided, that if such Election and Questionnaire is delivered during a Deferral Period, the Company shall so
inform the Holder delivering such Election and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance with Section 3(i). Notwithstanding anything
contained herein to the contrary, (i) the Company shall be under no obligation to name any Holder that is not an Election Holder as a selling securityholder in any Registration Statement or related Prospectus and (ii) the Amendment
Effectiveness Deadline Date shall be extended by up to fifteen (15) Business Days from the expiration of a Deferral Period if such Deferral Period shall be in effect on the Amendment Effectiveness Deadline Date. 
 (e) The parties hereto agree that the Holders of Notes that are Registrable Securities will suffer damages, and that it would not be feasible to
ascertain the extent of such damages with precision, if, other than as permitted hereunder, 
 (i) the Initial Shelf
Registration Statement has not been filed on or prior to the Filing Deadline Date, 
 (ii) the Initial Shelf Registration
Statement has not been declared effective under the Securities Act on or prior to the Effectiveness Deadline Date, or 
 (iii)
the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period pursuant to Section 3(i) hereof. 
 Each event described in any of the foregoing clauses (i) through (iii) is individually referred to herein as an “Event.” For purposes of this Agreement, each Event set forth above shall begin and end on the dates
set forth in the table set forth below: 
  

					
	 Type of
Event by
Clause
	  	 Beginning Date
	  	 Ending Date

			
	(i)	  	Filing Deadline Date	  	the date the Initial Shelf Registration Statement is filed
			
	(ii)	  	Effectiveness Deadline Date	  	the date the Initial Shelf Registration Statement becomes effective under the Securities Act
			
	(iii)	  	the date on which the aggregate duration of Deferral Periods in any period exceeds the number of days permitted by Section 3(i)	  	termination of the Deferral Period that caused the limit on the aggregate duration of Deferral Periods to be exceeded

  

 6 

 Commencing on (and including) any date that an Event has begun and ending on (but excluding) the next
date on which there are no Events that have occurred and are continuing (a “Damages Accrual Period”), the Company shall pay, as additional interest and not as a penalty, to Record Holders of Notes that are Registrable Securities an
amount accruing, for each day in the Damages Accrual Period, in respect of any Note, at a rate per annum equal to (A) 0.25% of the aggregate principal amount of such Note to and including the 90th calendar day of the Damages Accrual Period and
(B) 0.50% of the aggregate principal amount of such Note from and after the 91st calendar day of the Damages Accrual Period (the “Additional Interest Amount”). Notwithstanding the foregoing, no Additional Interest Amount shall
accrue as to any Note that is a Registrable Security from and after the date such Note is no longer a Registrable Security. The rate of accrual of the Additional Interest Amount with respect to any period shall not exceed the rate provided for in
this paragraph notwithstanding the occurrence of multiple concurrent Events. Following the cure of all Events relating to any particular Note, the accrual of the Additional Interest Amount with respect to such Note shall cease. 
 The Additional Interest Amount shall accrue from the first day of the applicable Damages Accrual Period, and shall be payable on each Damages Payment
Date during the Damages Accrual Period (and on the Damages Payment Date next succeeding the end of the Damages Accrual Period if the Damages Accrual Period does not end on a Damages Payment Date) to the Record Holders of Notes that are Registrable
Securities entitled thereto; provided, that any Additional Interest Amount accrued with respect to any Note or portion thereof redeemed by the Company on a redemption date, or repurchased by the Company on a repurchase date in connection with
a Fundamental Change, in either case that is after a Damages Payment Date and before the next Record Date, shall, in any such event, be paid on the applicable redemption date or repurchase date, as the case may be, instead to the Holder who
submitted such Note or portion thereof for redemption on the applicable redemption date or repurchase on the applicable repurchase date; provided, further, that any Additional Interest Amount accrued with respect to any Note or portion
thereof converted into Underlying Common Stock in connection with a Fundamental Change shall be paid on the conversion date instead to the Holder that submitted such Note or portion thereof for conversion. The Trustee shall be entitled, on behalf of
registered holders of Notes, to seek any available remedy for the enforcement of this Agreement, including for the payment of such Additional Interest Amount. Notwithstanding the foregoing, the parties agree that the sole damages payable for a
violation of the terms of this Agreement with respect to which the Additional Interest Amount is expressly provided shall be such Additional Interest 

  

 7 

 
Amount. Nothing shall preclude any Holder from pursuing or obtaining specific performance or other equitable relief with respect to this Agreement.

 All of the Company’s obligations set forth in this Section 2(e) to pay any Additional Interest Amount that is outstanding with
respect to any Note that is a Registrable Security at the time such Note ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such Note have been satisfied in full (notwithstanding termination of
this Agreement pursuant to Section 8(l)8(l) hereof). 
 The parties hereto agree that the Additional Interest Amount provided for in
this Section 2(e) constitutes a reasonable estimate of the damages that may be incurred by Holders of Notes that are Registrable Securities by reason of the failure of the Shelf Registration Statement to be filed or declared effective or
available for effecting resales of Notes that are Registrable Securities in accordance with the provisions hereof. 
 SECTION 3 .
Registration Procedures. In connection with the registration obligations of the Company under Section 2 hereof, during the Effectiveness Period the Company shall: 
 (a) Upon the request of any Holder, the Company shall promptly deliver the Election and Questionnaire to such Holders of Registrable Securities. No
Holder shall be entitled to be named as a selling securityholder in the Registration Statement as of its effective date, and no Holder shall be entitled to use the Prospectus forming a part thereof for resales of Registrable Securities at any time,
unless such Holder has returned a completed and signed Election and Questionnaire to the Company by the deadline for response set forth therein. 
 (b) Before filing any Registration Statement or Prospectus or any amendments or supplements thereto with the Commission (other than any supplements that do nothing more substantive than name one or more Election Holders as selling
securityholders), furnish to the Initial Purchasers and the Special Counsel of such offering, if any, copies of all documents proposed to be filed at least three (3) Business Days prior to the filing of such Registration Statement or amendment
thereto or Prospectus or supplement thereto. 
 (c) Subject to Section 3(i) hereof, prepare and file with the Commission such amendments
and post-effective amendments to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable period specified in Section 2(a) hereof; cause the related Prospectus to be
supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and use its reasonable best efforts to comply with the provisions of the
Securities Act applicable to it with respect to the disposition of all securities covered by such Registration Statement during the Effectiveness Period in accordance with the intended methods of disposition by the sellers thereof set forth in such
Registration Statement as so amended or such Prospectus as so supplemented. 
 (d) As promptly as practicable give notice to the Election
Holders, (i) when any Prospectus or Registration Statement has been filed with the Commission and, with respect to a Registration Statement, when the same has been declared effective (at which time, the Company shall also, upon the request of
any Holder of Registrable Securities that is not then an Election Holder, promptly send an Election and Questionnaire to such Holder); provided, however, that the 

  

 8 

 
Company shall not be required by this clause (i) to notify any Election Holder of the filing of a supplement to any Prospectus that does nothing more
substantive than name one or more other Election Holders as selling securityholders, (ii) of any request, following the effectiveness of the Initial Shelf Registration Statement under the Securities Act, by the Commission or any other federal
or state governmental authority for amendments or supplements to any Registration Statement or related Prospectus or for additional information related thereto, (iii) of the issuance by the Commission or any other federal or state governmental
authority of any stop order suspending the effectiveness of any Registration Statement or the initiation or threatening of any proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (v) of the occurrence of, but not the nature of or
details concerning, a Material Event (provided, that no notice by the Company shall be required pursuant to this clause (v) in the event that the Company either promptly files a supplement to update the Prospectus or a Current Report on
Form 8-K or other appropriate Exchange Act report that is incorporated by reference into the Registration Statement, which, in any case, contains the requisite information with respect to such Material Event that results in such Registration
Statement no longer containing any untrue statement of a material fact or omitting to state a material fact necessary to make the statement contained therein not misleading) and (vi) of the determination by the Company that a post-effective
amendment to a Registration Statement will be filed with the Commission, which notice may, at the discretion of the Company (or as required pursuant to Section 3(i)), state that it constitutes a Deferral Notice, in which event the provisions of
Section 3(i) shall apply. 
 (e) Use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a
Registration Statement or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which they have been qualified for sale, in either case, as promptly
as practicable, and provide prompt notice to each Election Holder and the Initial Purchasers of the withdrawal of any such order. 
 (f) As
promptly as practicable, furnish to each Election Holder, the Special Counsel and the Initial Purchasers, upon request and without charge, at least one (1) conformed copy of the Registration Statement and any amendment thereto, including
exhibits filed with any Registration Statement or amendment, unless such documents are available on the Electronic Data Gathering, Analysis, and Retrieval system of the Commission (“EDGAR”). 
 (g) During the Effectiveness Period, deliver to each Election Holder, in connection with any sale of Registrable Securities pursuant to a Registration
Statement, without charge, as many copies of the Prospectus or Prospectuses relating to such Registrable Securities (including each preliminary Prospectus) and any amendment or supplement thereto as such Election Holder may reasonably request; and
the Company hereby consents (except during such periods that a Deferral Notice is outstanding and has not been revoked) to the use of such Prospectus or each amendment or supplement thereto, by each Election Holder in connection with any offering
and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto in the manner set forth therein. 
  

 9 

 (h) Prior to any public offering of the Registrable Securities pursuant to a Registration Statement, use
its reasonable best efforts to register or qualify or cooperate with the Election Holders and the Special Counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Election Holder reasonably requests in writing (which request may be included in the Election and Questionnaire); prior to any
public offering of the Registrable Securities pursuant to the Shelf Registration Statement, use its reasonable best efforts to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness Period in
connection with such Election Holder’s offer and sale of Registrable Securities pursuant to such registration or qualification (or exemption therefrom) and do any and all other acts or things reasonably necessary or advisable to enable the
disposition in such jurisdictions of such Registrable Securities in the manner set forth in the relevant Registration Statement and the related Prospectus; provided, that the Company will not be required to (i) qualify as a foreign
corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Agreement or (ii) take any action that would subject it to general service of process in suits or to taxation in any
such jurisdiction where it is not then so subject. 
 (i) Upon (w) the issuance by the Commission of a stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of proceedings with respect to the Shelf Registration Statement under Section 8(d) or 8(e) of the Securities Act, (x) the occurrence of any event or the existence of any
fact (a “Material Event”) as a result of which any Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the
statements therein not misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, (y) the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction or the initiation or threatening of any proceeding for such purpose or (z) the occurrence or existence of any pending corporate development that, in the reasonable discretion of the Company, makes it appropriate to suspend the
availability of the Shelf Registration Statement and the related Prospectus: 
 (i) in the case of clause (x) above,
subject to the next sentence, as promptly as practicable, prepare and file, if necessary pursuant to applicable law, a post-effective amendment to such Registration Statement or a supplement to the related Prospectus or any document incorporated
therein by reference or file any other required document that would be incorporated by reference into such Registration Statement and Prospectus so that such Registration Statement does not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the statements therein not misleading, and such Prospectus does not contain any untrue statement of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, and, in the case of a
post-effective 

  

 10 

 
amendment to a Registration Statement, subject to the next sentence, use its reasonable best efforts to cause it to be declared effective as promptly as is
practicable, and 
 (ii) give notice to the Election Holders that the availability of the Shelf Registration Statement is
suspended (a “Deferral Notice”) and, upon receipt of any Deferral Notice, each Election Holder agrees not to sell any Registrable Securities pursuant to the Registration Statement until such Election Holder’s receipt of copies
of the supplemented or amended Prospectus provided for in clause (i) above, or until it is advised in writing by the Company that the Prospectus may be used, and has received copies of any additional or supplemental filings that are
incorporated or deemed incorporated by reference in such Prospectus (except to the extent available on EDGAR), and such Holder will either (X) destroy any Prospectuses, other than permanent file copies, then in such Holder’s possession
that have been replaced by the Company with more recently dated prospectuses or (Y) deliver to the Company (at the Company’s expense) all copies in such Holder’s possession, other than permanent file copies then in such Holder’s
possession, of the Prospectus covering such Registrable Securities, current at the time of receipt of such notice. 
 The Company will use
its reasonable best efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (w) and (y) above, as promptly as is practicable, (y) in the case of clause (x) above, as soon as, in the sole
judgment of the Company, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of the Company or, if necessary to avoid unreasonable burden or expense, as soon as practicable thereafter and (z) in the
case of clause (z) above, as soon as in the reasonable discretion of the Company, such suspension is no longer appropriate. Any period during which the availability of the Shelf Registration Statement and any Prospectus is suspended
(the “Deferral Period”) shall, without incurring any obligation to pay the Additional Interest Amount pursuant to Section 2(e), not exceed 45 calendar days in any 90 calendar-day period (or 60 calendar days in any 90
calendar-day period in the event of a Material Event pursuant to which the Company has delivered a second notice as permitted below) or 120 calendar days in any 360 calendar-day period; provided, that in the case of a Material Event relating
to an acquisition or a probable acquisition, financing, recapitalization, business combination or other similar transaction, the Company may, without incurring any obligation to pay the Additional Interest Amount pursuant to Section 2(e),
deliver to Election Holders a second notice to the effect set forth above, which shall have the effect of extending the Deferral Period by up to an additional 15 calendar days, or such shorter period of time as is specified in such second notice.

 (j) Not later than the effective date of the Registration Statement, the Company shall cause the Indenture to be qualified under the TIA;
in connection with such qualification, the Company shall cooperate with the Trustee under the Indenture and the Holders (as defined in the Indenture) to effect such changes to the Indenture as may be required for such Indenture to be so qualified in
accordance with the terms of the TIA; and the Company shall execute, and shall use commercially reasonable efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required
to be filed with the Commission to enable such Indenture to be so qualified in a timely manner. In the event that any such amendment or modification referred to in this Section 3(j) involves the appointment of a 

  

 11 

 
new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 
 (k) If requested in writing in connection with a disposition of Registrable Securities in an aggregate amount of at least $5 million pursuant to a
Registration Statement, make reasonably available for inspection during normal business hours by a representative for the Election Holders of such Registrable Securities, any broker-dealers, attorneys and accountants retained by such Election
Holders, and any attorneys or other agents retained by a broker-dealer engaged by such Election Holders, all relevant financial and other records and pertinent corporate documents and properties of the Company and its subsidiaries, and cause the
appropriate officers, directors and employees of the Company and its subsidiaries to make reasonably available for inspection during normal business hours on reasonable notice all relevant information reasonably requested by such representative for
the Election Holders, or any such broker-dealers, attorneys or accountants in connection with such disposition, in each case, as is customary and reasonably necessary for similar “due diligence” examinations; provided, that such
persons shall first agree in writing with the Company that any non-public information shall be kept confidential by such persons and shall be used solely for the purposes of exercising rights under this Agreement, unless (w) disclosure of such
information is required by court or administrative order or is necessary to respond to inquiries of regulatory authorities, (x) disclosure of such information is required by law (including any disclosure requirements pursuant to federal
securities laws in connection with the filing of any Registration Statement or the use of any prospectus referred to in this Agreement), (y) such information becomes generally available to the public other than as a result of a disclosure or
failure to safeguard by any such person or (z) such information becomes available to any such person from a source other than the Company and such source is not bound by a confidentiality agreement, and provided, further, that the
foregoing inspection and information gathering shall, to the greatest extent possible, be coordinated on behalf of all the Election Holders and the other parties entitled thereto by Special Counsel. Any person legally compelled to disclose any such
confidential information made available for inspection shall provide the Company with prompt prior written notice of such requirement so that the Company may seek a protective order or other appropriate remedy. 
 (l) Comply in all material respects with all applicable rules and regulations of the Commission and make generally available to its securityholders
earning statements (which need not be audited) satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) for a 12-month period commencing on the first day
of the first fiscal quarter of the Company commencing after the effective date of a Registration Statement. 
 (m) Cooperate with each
Election Holder to facilitate the timely preparation and delivery of certificates representing Registrable Securities sold or to be sold pursuant to a Registration Statement, which certificates shall not bear any restrictive legends, and cause such
Registrable Securities to be in such denominations as are permitted by the Indenture and registered in such names as such Election Holder may request in writing at least two (2) Business Days prior to any sale of such Registrable Securities.

 (n) Provide a CUSIP number from Standard & Poor’s CUSIP Bureau for all Registrable Securities covered by each Registration
Statement not later than the effective date of 

  

 12 

 
such Registration Statement and provide the Trustee and the transfer agent for the Common Stock with printed certificates for the Registrable Securities that
are in a form eligible for deposit with The Depository Trust Company. 
 (o) The Company will use its best efforts to cause the Underlying
Common Stock issuable upon conversion of the Securities to be listed on the New York Stock Exchange or other stock exchange or trading system on which the Common Stock primarily trades on or prior to the effective date of the Registration Statement
hereunder. 
 (p) Reasonably cooperate and assist in any filings required to be made with the National Association of Securities Dealers,
Inc. 
 (q) Upon the filing of the Initial Shelf Registration Statement, announce the same, by release to Reuters Economic Services and
Bloomberg Business News and by delivery of written notice by first class mail to the Holders at their addresses set forth in the Note Register of the Note Registrar. 
 (r) Upon the effectiveness of the Initial Shelf Registration Statement, announce the same, by release to Reuters Economic Services and Bloomberg Business News. 
 SECTION 4 . Holder’s Obligations. Each Holder agrees, by acquisition of the Registrable Securities, that no Holder shall be entitled to sell
any of such Registrable Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto, unless such Holder has furnished the Company with an Election and Questionnaire as required pursuant to Section 2(d) hereof
(including the information required to be included in such Election and Questionnaire) and the information set forth in the next sentence. Each Election Holder agrees to furnish promptly to the Company all information required to be disclosed in
order to make the information previously furnished to the Company by such Election Holder not misleading and any other information regarding such Election Holder and the distribution of such Registrable Securities as the Company may from time to
time reasonably request. Any sale of any Registrable Securities by any Holder shall constitute a representation and warranty by such Holder that the information relating to such Holder and its plan of distribution is as set forth in the Prospectus
delivered by such Holder in connection with such disposition, that such Prospectus does not as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its plan of distribution and that such
Prospectus does not as of the time of such sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the statements in such Prospectus, in the light of the circumstances under which
they were made, not misleading. 
 SECTION 5 . Registration Expenses. The Company shall bear all fees and expenses incurred in
connection with the performance by the Company of its obligations under Section 2 and 3 of this Agreement whether or not any Registration Statement is declared effective. Such fees and expenses shall include, without limitation, (a) all
registration and filing fees (including, without limitation, fees and expenses (x) with respect to filings required to be made with the National Association of Securities Dealers, Inc. and (y) of compliance with federal and state
securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of the Special Counsel in connection with Blue Sky qualifications of the Registrable Securities under the laws of such jurisdictions as Election Holders of
a majority of the Registrable Securities 

  

 13 

 
being sold pursuant to a Registration Statement may designate), (b) printing expenses (including, without limitation, expenses of printing certificates
for Registrable Securities in a form eligible for deposit with The Depository Trust Company), (c) duplication expenses relating to copies of any Registration Statement or Prospectus delivered to any Holders hereunder, (d) fees and
disbursements of counsel for the Company in connection with the Shelf Registration Statement, (e) reasonable fees and disbursements of the Trustee and its counsel and of the Note Registrar and Transfer Agent for the Common Stock and
(f) any Securities Act liability insurance obtained by the Company in its sole discretion. In addition, the Company shall pay the internal expenses of the Company (including, without limitation, all salaries and expenses of officers and
employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing by the Company of the Registrable Securities on any securities exchange on which similar securities of
the Company are then listed, if any listing is made, and the fees and expenses of any person, including special experts, retained by the Company. Notwithstanding the provisions of this Section 5, each Holder of Registrable Securities shall pay
its selling expenses, including any underwriting discount and commissions, and its registration expenses to the extent required by applicable law. 
 SECTION 6 . Indemnification and Contribution. 
 (a) Indemnification by the Company. The Company agrees to indemnify
and hold harmless each Election Holder, each person, if any, who controls any Election Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each Affiliate of any Election Holder within
the meaning of Rule 405 under the Securities Act that is a broker-dealer from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) caused by any (i) untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any amendment thereof, caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) untrue statement or alleged untrue statement of a material fact contained in the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements thereto) at the time of sale, caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the
statements therein in light of the circumstances under which they were made not misleading, except in each of (i) and (ii) above insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any Holder furnished to the Company in writing by such Holder expressly for use therein. 
 (b) Indemnification by Holders. Each Holder, severally and not jointly, agrees to indemnify and hold harmless the Company and its directors, officers and each person, if any, who controls the Company (within
the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) or any other Holder, to the same extent as the foregoing indemnity from the Company to such Holder, but only with reference to information relating
to such Holder furnished to the Company in writing by such Holder expressly for use in the Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of any Holder hereunder be greater in amount than the
dollar amount of the proceeds received by 

  

 14 

 
such Holder upon the sale of the Registrable Securities pursuant to the Registration Statement giving rise to such indemnification obligation. 
 (c) Conduct of Indemnification Proceedings. In case any proceeding (including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to Section 6(a) or 6(b) hereof, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the
“indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any
such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between
them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more
than one separate firm (in addition to any local counsel at its standard non-premium rates) for all such indemnified parties and that all such fees and expenses shall be promptly reimbursed. Such firm shall be designated in writing by, in the case
of parties indemnified pursuant to Section 6(a), the Holders of a majority (with Holders of Notes deemed to be the Holders, for purposes of determining such majority, of the number of shares of Underlying Common Stock into which such Notes are
or would be convertible as of the date on which such designation is made) of the Registrable Securities covered by the Registration Statement held by Holders that are indemnified parties pursuant to Section 6(a) and, in the case of parties
indemnified pursuant to Section 6(b), the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the
plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment that is indemnifiable pursuant to Section 6(a) or 6(b), as the case may be.
Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this
paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such settlement; provided, that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party, prior to the
date of such settlement, (1) reimburses such indemnified party in accordance with such request for the amount of such fees and expenses of counsel as the indemnifying party believes in good faith to be reasonable, and (2) provides written
notice to the indemnified party that the indemnifying party disputes in good faith the reasonableness of the unpaid balance of such fees and expenses. No indemnifying party shall, without the prior written consent of the indemnified party, effect
any 

  

 15 

 
settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. 
 (d) Contribution. To the extent that the indemnification provided for in Section 6(a) or 6(b) is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under Section 6(a) or 6(b), as applicable, in lieu of indemnifying such indemnified party thereunder, shall contribute to
the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one
hand and the indemnified party or parties on the other hand or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering and sale of the Notes to the Initial
Purchasers made pursuant to the Purchase Agreement (before deducting expenses) of the Registrable Securities to which such losses, claims, damages or liabilities relate. The relative benefits received by any Holder shall be deemed to be equal to the
value of receiving Registrable Securities that are registered under the Securities Act. The relative fault of the Holders on the one hand and the Company on the other hand shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Holders or by the Company, and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Holders’ respective obligations to contribute pursuant to this Section 6(d) are several in proportion to the respective number of Registrable Securities they have sold
pursuant to a Registration Statement, and not joint. 
 The parties hereto agree that it would not be just and equitable if contribution
pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding this Section 6, no indemnifying party that is a selling Holder shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable Securities sold by it and distributed to the public were offered to the public exceeds the amount of any damages that such indemnifying party has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. 
  

 16 

 (e) The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to an indemnified party at law or in equity, hereunder, under the Purchase Agreement or otherwise. 
 (f) The indemnity and contribution provisions contained in this Section 6 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of
any Holder, any person controlling any Holder or any Affiliate of any Holder or by or on behalf of the Company, their officers or directors or any person controlling the Company and (iii) the sale of any Registrable Securities by any Holder.

 SECTION 7 . Information Requirements. The Company covenants that, if at any time before the end of the Effectiveness Period the
Company is not subject to the reporting requirements of the Exchange Act, it will cooperate with any Holder and take such further reasonable action as any Holder may reasonably request in writing (including, without limitation, making such
reasonable representations as any such Holder may reasonably request), all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 and Rule 144A under the Securities Act and customarily taken in connection with sales pursuant to such exemption. Upon the written request of any Holder, the Company shall deliver to such Holder a written statement as
to whether it has complied with such filing requirements, unless such a statement has been included in the Company’s most recent report filed pursuant to Section 13 or Section 15(d) of Exchange Act. Notwithstanding the foregoing,
nothing in this 07 shall be deemed to require the Company to register any of its securities (other than the Common Stock) under any section of the Exchange Act. 
 SECTION 8 . Miscellaneous. 
 (a) No Conflicting Agreements. The Company is not, as of the date
hereof, a party to, nor shall it, on or after the date of this Agreement, enter into, any agreement with respect to its securities that conflicts with the rights granted to the Holders in this Agreement. The Company represents and warrants that the
rights granted to the Holders hereunder do not in any way conflict with the rights granted to the holders of the Company’s securities under any other agreements. 
 (b) Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if the Company fails to perform any of its obligations hereunder and that the Initial Purchasers and the
Holders from time to time may be irreparably harmed by any such failure, and accordingly agree that the Initial Purchasers and such Holders, in addition to any other remedy to which they may be entitled at law or in equity and without limiting the
remedies available to the Election Holders under Section 2(e) hereof, shall be entitled to compel specific performance of the obligations of the Company under this Agreement in accordance with the terms and conditions of this Agreement, in any
court of the United States or any State thereof having jurisdiction. 
 (c) Amendments and Waivers. Except as provided in the next
paragraph, the provisions of this Agreement, including the provisions of this sentence, may not be amended, 

  

 17 

 
modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written
consent of Holders of a majority of the then outstanding Underlying Common Stock constituting Registrable Securities (with Holders of Notes deemed to be the Holders, for purposes of this Section, of the number of outstanding shares of Underlying
Common Stock into which such Notes are or would be convertible as of the date on which such consent is requested). Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders whose securities are being sold pursuant to a Registration Statement and that does not affect the rights of other Holders may be given by Holders of a majority of the Registrable Securities being sold by such
Holders pursuant to such Registration Statement; provided that the provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the immediately preceding sentence. Notwithstanding the
foregoing two sentences, this Agreement may be amended by written agreement signed by the Company and the Initial Purchasers, without the consent of the Holders of Registrable Securities, to cure any ambiguity or to correct or supplement any
provision contained herein that may be defective or inconsistent with any other provision contained herein, or to make such other provisions in regard to matters or questions arising under this Agreement that shall not adversely affect the interests
of the Holders of Registrable Securities. Each Holder of Registrable Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or thereafter shall be bound by any such amendment, modification, supplement,
waiver or consent effected pursuant to this Section 8(b)8(c), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or consent appears on the Registrable Securities or is delivered to such
Holder. 
 To the extent that any Notes remain outstanding, upon a merger or consolidation or sale, conveyance, transfer or lease of all or
substantially all of the properties and assets of the Company in which the person (if other than the Company) formed by such consolidation or into which the Company is merged or the person who acquires by sale, conveyance, transfer or lease all or
substantially all of the properties and assets of the Company assumes the Company’s obligations under the Indenture and the Notes, the Company shall procure the assumption of its obligations under this Agreement by such person, and this
Agreement may be amended, modified or supplemented without the consent of any Holders to provide for such assumption of the Company’s obligations hereunder. Without the consent of each Holder of Notes, no amendment or modification may change
the provisions relating to the payment of the Additional Interest Amount. 
 (d) Notices. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand delivery, by telecopier, by courier guaranteeing overnight delivery or by first-class mail, return receipt requested, and shall be deemed given (i) when made, if made by hand
delivery, (ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after being deposited with such courier, if made by overnight courier or (iv) on the date indicated on the notice of receipt, if made by

 (e) Approval of Holders. Whenever the consent or approval of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable Securities held by the Company or its Affiliates
(other than the Initial Purchasers or subsequent Holders if such subsequent Holders are deemed to be such Affiliates solely by reason of their holdings of such Registrable Securities) shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage. 
 (f) Successors and Assigns. Any person who purchases any Registrable
Securities from the Initial Purchasers shall be deemed, for purposes of this Agreement, to be an assignee of the Initial Purchasers. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties
and shall inure to the benefit of and be binding upon each Holder of any Registrable Securities, provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of
the terms of the Indenture. If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of the terms of this Agreement, and

efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction, it being intended that all of the rights and privileges of the parties shall
be enforceable to the fullest extent permitted by law. 
 (k) Entire Agreement. This Agreement is intended by the parties as a final
expression of their agreement and, is intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted by the Company
with respect to the Registrable Securities. Except as provided in the Purchase Agreement, there are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein, with respect to the registration rights
granted by the Company with respect to the Registrable Securities. This Agreement supersedes all prior agreements and undertakings among the parties with respect to such registration rights. No party hereto shall have any rights, duties or
obligations other than those specifically set forth in this Agreement. 
 (l) Termination. This Agreement and the obligations of the
parties hereunder shall terminate upon the end of the Effectiveness Period, except for any liabilities or obligations under Section 4, 5, 6 or 9 hereof and the obligations to make payments of and provide for the Additional Interest Amount under
