 (e) Denominations. Pursuant to
Sections 301 and 302 of the Base Indenture, the Securities will be issued only in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. 

Section 2.02 Forms.

 12 








 (c) Global Securities. Each Global Security will represent the aggregate principal
amount of the then Outstanding Securities endorsed thereon and provide that it represents such aggregate principal amount of the then Outstanding Securities, which aggregate principal amount may, from time to time, be reduced or increased to reflect
transfers, exchanges, conversions or purchases by the Company. 
 Only the Trustee, or the Custodian holding such Global Security for
the Depository, at the direction of the Trustee, may endorse a Global Security to reflect the amount of any increase or decrease in the aggregate principal amount of the then Outstanding Securities represented thereby, and whenever the Holder of a
beneficial interest in a Global Security delivers instructions to the Trustee to increase or decrease the aggregate principal amount of the then Outstanding Securities represented by a Global Security in accordance with the Indenture and the
Applicable Procedures, the Trustee, or the Custodian holding such Global Security for the Depository, at the direction of the Trustee, will endorse such Global Security to reflect such increase or decrease in the aggregate principal amount of the
then Outstanding Securities represented thereby. None of the Trustee, the Company or any agent of the Trustee or the Company will have any responsibility or bear any liability for any aspect of the records relating to or payments made on account of
the ownership of any beneficial interest in a Global Security or with respect to maintaining, supervising or reviewing any records relating to such beneficial interest. 

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect
to any Global Security held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Security, and Cede & Co., or such other person designated by the Depository as its nominee, may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the

and the Security Registrar. 
 At such time as all interests in a Global Security have been purchased, converted, cancelled or
exchanged for Securities in certificated form, such Global Security shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depository and the Custodian for the Global

Procedures and the provisions of the Indenture, and each Global Security may be transferred only as a whole and only (A) by the Depository to a nominee of the Depository, (B) by a nominee of the Depository to the Depository or to another
nominee of the Depository, or (C) by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. 

(c) Holders Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any interest (subject to Section 307 of the Base
Indenture) on such Security at the Maturity Date, in connection with a Fundamental Change, upon any conversion and for all other purposes whatsoever, including delivery of shares of Common Stock on conversion, for distribution of notices to such

withdraw any Securities surrendered for purchase prior to the Fundamental Change Expiration Time; and 
 (10) the procedures that Holders
must follow to require the Company to purchase their Securities. 
 No failure of the Company to give the foregoing notices and no defect
therein shall limit the purchase rights of the Holders of Securities or affect the validity of the proceedings for the purchase of the Securities pursuant to this Section 3.02. 

(c) Notwithstanding the foregoing, there shall be no purchase of any Securities pursuant to this Section 3.02 if the principal amount of
the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date

(3) the principal amount, if any, of each Security that remains subject to the Fundamental Change Purchase Notice, which must be such that the
principal amount not to be purchased equals $1,000 or an integral multiple of $1,000 in excess thereof; 
 provided, however, that if the
Securities are Global Securities, the notice must comply with Applicable Procedures of the Depository. 
 The Paying Agent will promptly
return to the respective Holders thereof any Physical Securities with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.04. 

Section 3.05 Deposit of Fundamental Change Purchase Price. One Business Day prior to the Fundamental Change Purchase Date, the
Company shall deposit with the Paying Agent 

  
 20 








 
(or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately
available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash
sufficient to pay the Fundamental Change Purchase Price of the Securities for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture on the Fundamental Change Purchase Date, then as of such
Fundamental Change Purchase Date, (a) such Securities will cease to be Outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Securities is made or such Securities have been delivered to the Paying
Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery or book-entry transfer of such Securities). 

Section 3.06 Securities Purchased in Whole or in Part. Any Security that is to be purchased, whether in whole or in part, shall be
surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Securities, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or
Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 

Section 3.07 Covenant To Comply with Applicable Laws upon Purchase of Securities. In connection with any offer to purchase
Securities under Section 3.02, the Company shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or
any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws applicable to the Company in connection with such purchase offer, in each case, so as to permit the rights and obligations
under Section 3.02 to be exercised in the time and in the manner specified in Section 3.02. 
 Section 3.08 Repayment to
the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.05 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to
purchase as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company. 

ARTICLE 4 
 CONVERSION

 Section 4.01 Right To Convert. (a) Subject to and upon compliance with the provisions of the Indenture, each Holder
shall have the right, at such Holder’s option, to convert 

  
 21 








 
its Securities, or any portion of its Securities such that the principal amount that remains Outstanding of each Security that is not converted in full equals $1,000 or an integral multiple of
$1,000 in excess thereof, into the Settlement Amount determined in accordance with Section 4.03(a) hereof, (x) prior to the Close of Business on the Business Day immediately preceding October 1, 2020, only upon satisfaction of one or
more of the conditions described in Section 4.01(b) hereof, and (y) on or after October 1, 2020, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date. 

(b) (1) A Holder may surrender Securities for conversion during any fiscal quarter commencing after June 30, 2014 (and only during such
fiscal quarter) if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter
is greater than or equal to 130% of the Conversion Price in effect on each Trading Day. 
 (2) A Holder may surrender Securities for
conversion during the five Business Day period after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Securities, as determined following a request by a
Holder in accordance with the procedures set forth in this Section 4.01(b)(2), for each Trading Day of such Measurement Period was less than 98% of the product of (i) the Conversion Rate in effect on such Trading Day and (ii) the Last
Reported Sale Price of the Common Stock on such Trading Day. The Trading Price shall be determined by the Bid Solicitation Agent pursuant to this Section 4.01(b)(2) and the definition of “Trading Price” set forth in Section 1.02
hereof. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company in accordance with the definition of Trading Price,
along with the appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price of the Securities unless the Company has requested such determination; and the
Company shall have no obligation to make such request (or, if the Company is the Bid Solicitation Agent, to determine the Trading Price of the Securities) unless a Holder of a Security provides it with reasonable evidence that the Trading Price per
$1,000 principal amount of Securities would be less than 98% of the product of (i) the Conversion Rate in effect on the next Trading Day and (ii) the Last Reported Sale Price of the Common Stock on such Trading Day. At such time, the
Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine (or, if the Company is the Bid Solicitation Agent, the Company shall determine) the Trading Price per $1,000 principal amount of the Securities beginning on
the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Securities for a Trading Day is greater than or equal to 98% of the product of (i) the Conversion Rate in effect on such Trading Day
and (ii) the Last Reported Sale Price of the Common Stock on such Trading Day. Whenever the condition to conversion set forth in this Section 4.01(b)(2) has been met, but was not met on the immediately preceding Trading Day, the Company
will so notify the Holders and the Trustee. If, at any time after the condition to conversion set forth in this Section 4.01(b)(2) has been met, the condition to conversion set forth in this Section 4.01(b)(2) ceases to be met, the Company
will so notify the Holders and the Trustee on the first Trading Day on which such condition ceases to be met. 

  
 22 








 (3) If the Company elects to (x) issue to all or substantially all holders of the Common
Stock rights, options or warrants entitling them for a period of not more than 45 calendar days after the date of such issuance to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Last Reported
Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance; or (y) distribute to all or substantially all holders of the Common Stock the
Company’s assets, debt securities or rights to purchase the Company’s securities, which distribution has a per-share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common
Stock on, and including, the Trading Day immediately preceding the date of announcement for such distribution, then, the Company must deliver notice of such issuance or distribution, and of the Ex-Dividend Date for such issuance or distribution, to
the Holders at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Holders may surrender their Securities for conversion at any time during the period beginning on the 25th Scheduled Trading Day
immediately prior to the Ex-Dividend Date for such issuance or distribution and ending on the earlier of (a) the Close of Business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution or (b) its
announcement that such issuance or distribution will not take place, even if the Securities are not otherwise convertible at such time; provided, however, that Holders may not convert their Securities pursuant to this
Section 4.01(b)(3) if the Company provides that Holders shall participate, at the same time and upon the same terms as holders of the Common Stock, and as a result of holding the Securities, in the relevant issuance or distribution without
having to convert their Securities as if they held a number of shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such issuance or distribution multiplied by the principal amount (expressed in
thousands) of Securities held by such Holder on the Ex-Dividend Date for such issuance or distribution. 
 (4) If (i) a Make-Whole
Fundamental Change occurs or (ii) the Company is a party to (a) a consolidation, merger, binding share exchange, pursuant to which the Common Stock would be converted into cash, securities or other assets or (b) a sale, conveyance,
transfer or lease of all or substantially all of the assets of the Company and its Subsidiaries, on a consolidated basis, to another person (other than any of the Company’s Subsidiaries), the Securities may be surrendered for conversion at any
time from or after the date that is 25 Scheduled Trading Days prior to the anticipated Fundamental Change Effective Date or the anticipated effective date of such sale, conveyance, transfer or lease, as the case may be (or, if later, the Business
Day after the Company gives notice of such transaction) until the Close of Business (i) if such transaction is a Fundamental Change, on the Business Day immediately preceding the Fundamental Change Purchase Date, and, (ii) otherwise, on
the 35th Business Day immediately following the effective date for such transaction. The Company will notify the Holders of any such transaction: 

(A) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 35 Scheduled
Trading Days prior to the anticipated effective date of such transaction; or 

  
 23 








 (B) if the Company does not have knowledge of such transaction at least 35 Scheduled Trading Days
prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such
transaction. 
 (c) Notwithstanding any other provision of the Securities or this Indenture, no Holder of Securities will be entitled to
receive Common Stock following conversion of such Securities to the extent that receipt of such Common Stock would cause such Holder to exceed the ownership limits contained in the Company’s charter. 

(d) If any delivery of shares of Common Stock owed to a Holder upon conversion of Securities is not made, in whole or in part, as a result of
the limitations described in Section 4.01(c), the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such shares as promptly as practicable after any such converting Holder gives notice to
the Company that such delivery would not result in it being the beneficial or constructive owner of more than 7.5% (by number or value) of the shares of Common Stock outstanding at such time. 

Section 4.02 Conversion Procedures. 

(a) Each Security shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures
of the Depository. 
 (b) To exercise the conversion privilege with respect to a beneficial interest in a Global Security, the Holder must
complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Conversion Agent, and pay the funds,
if any, required by Section 4.02(f) and any taxes or duties if required pursuant to Section 4.02(g), and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depository. 

To exercise the conversion privilege with respect to any Physical Securities, the Holder of such Physical Securities shall: 

(1) complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “Conversion
Notice”) or a facsimile of the Conversion Notice; 
 (2) deliver the Conversion Notice, which is irrevocable, and the Security to
the Conversion Agent; 
 (3) if required, furnish appropriate endorsements and transfer documents, 

  
 24 








 (4) if required, make any payment required under Section 4.02(f); and 

(5) if required, pay all transfer or similar taxes as set forth in Section 4.02(g). 

If, upon conversion of a Security, any shares of Common Stock are to be issued to a person other than the Holder of such Security, the related Conversion
Notice shall include such other person’s name and address. 
 If a Security is subject to a Fundamental Change Purchase Notice, such
Security may not be converted unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04 hereof prior to the relevant Fundamental Change Expiration Time. 

For any Security, the first Business Day on which the Holder of such Security satisfies all of the applicable requirements set forth
above with respect to such Security and on which conversion of such Security is not otherwise prohibited under this Indenture shall be the “Conversion Date” with respect to such Security. 

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) surrendered for conversion at the
Close of Business on the applicable Conversion Date; provided, however, that the person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as
of the Close of Business on (i) such Conversion Date (in the case of Physical Settlement) or (ii) the last Trading Day of the applicable Cash Settlement Averaging Period (in the case of Combination Settlement) except to the extent required
by Section 4.04 hereof. At the Close of Business on the Conversion Date for a Security, the converting Holder shall no longer be the Holder of such Security. 

(c) Endorsement. Any Securities surrendered for conversion shall, unless shares of Common Stock issuable on conversion are to be
issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney. 

(d) Physical Securities. If any Securities in a denomination greater than $1,000 shall be surrendered for partial conversion,
the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge, new Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of
the surrendered Securities that is in an authorized denomination. 
 (e) Global Securities. Upon the conversion of a
beneficial interest in Global Securities, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities
effected through any Conversion Agent other than the Trustee. 
 (f) Interest Due Upon Conversion. If Securities are converted
after the Close of Business on a Regular Record Date for the payment of interest, Holders of such Securities at the Close of Business on such Regular Record Date will receive the interest payable on such


  
 25 








 
Securities on the corresponding Interest Payment Date notwithstanding the conversion. If a Holder converts a Security after the Close of Business on a Regular Record Date but prior to the Open of
Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Security with an amount of cash equal to the amount of interest that will be payable on such Security on the corresponding Interest
Payment Date; provided, however, that a Holder need not make such payment (1) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental
Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date and the Holder converts its Security after the Close of Business on such Regular Record Date and on or prior to the Open of Business
on such 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 Security. For the avoidance of doubt, all Holders of Securities on the Regular Record
Date immediately preceding the Maturity Date and any Fundamental Change Purchase Date described in the preceding sentence will receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether
their Securities have been converted following such Regular Record Date. 
 (g) Taxes Due upon Conversion. If a Holder
converts a Security, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be issued in
a name other than the Holder’s name, in which case the Holder will pay that tax. 
 Section 4.03 Settlement Upon
Conversion. 
 (a) Settlement Amount. Subject to this Section 4.03, if a Holder converts a Security, the Company
shall pay or deliver to such Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, solely cash, solely shares of Common Stock or a combination of cash and Common Stock (the “Settlement
Amount”), at the Company’s election, as set forth in this Section 4.03. 
 (1) The Company shall pay or deliver,
as the case may be, the Settlement Amount on the third Trading Day immediately following the last Trading Day of the Cash Settlement Averaging Period; provided, that; 

(A) if the Company elects to fulfill its conversion obligation solely in shares of Common Stock, the Company shall deliver such Common Stock
on the third Trading Day immediately following the relevant Conversion Date; and 
 (B) if prior to the relevant Conversion Date, the Common
Stock has been replaced by Reference Property consisting solely of cash, pursuant to Section 4.07, the Company shall pay such cash on the third Trading Day immediately following the relevant Conversion Date. Notwithstanding the foregoing, if
any information required to calculate the conversion obligation is not available as of the applicable settlement date, the Company will deliver the additional shares of Common Stock resulting from such adjustment on the third Trading Day after the
earliest Trading Day on which such calculation can be made. 

  
 26 








 (2) All conversions during the Final Conversion Period will be settled in the same relative
proportions of cash and/or shares of Common Stock (the “Settlement Method”). 
 (3) Prior to the first day of the Final
Conversion Period, the Company will elect (or be deemed to have elected) the same Settlement Method for all conversions occurring on any given Conversion Day. Except for any conversions that occur during the Final Conversion Period, the Company need
not elect the same Settlement Method with respect to conversions that occur on different Conversion Dates. 
 (4) With respect to each
Conversion Date occurring prior to the Final Conversion Period, the Company shall deliver a notice (each, a “Settlement Notice”) of the relevant Settlement Method not later than the Close of Business on the second Trading Day
following the related Conversion Date. With respect to each Conversion Date occurring during the Final Conversion Period, the Company shall, prior to the Final Conversion Period, deliver a single Settlement Notice that shall apply to all conversions
occurring during the Final Conversion Period. Each such Settlement Notice shall specify whether the Company shall satisfy its conversion obligation by (i) delivering solely shares of Common Stock (“Physical Settlement”),
(ii) paying solely cash (“Cash Settlement”) or (iii) paying and delivering, as the case may be, a combination of cash and shares of Common Stock (“Combination Settlement”). In the case of an election that
provides for Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount. If the Company does not deliver a Settlement Notice within the time periods specified above, or if the Company provides a Settlement
Notice within the time periods specified above and elects Combination Settlement but the Settlement Notice does not specify a Specified Dollar Amount, the Company will be deemed to have elected Combination Settlement with a Specified Dollar Amount
of $1,000. Notwithstanding the foregoing, if the Company shall have made a Physical Settlement Election, then the Company shall no longer be required to provide the notices specified in this Section 4.03(a)(4) and the Company shall be required
to satisfy all conversion obligations resulting from conversions of notes subsequent to the Physical Settlement Election Date entirely in shares of Common Stock. 

(5) The Settlement Amount in respect of any conversion shall be computed as follows: 

(A) if the Company elects to satisfy its conversion obligation in respect of such conversion through Physical Settlement, the Company will
deliver to the converting Holder a number of shares of Common Stock equal to (1) (i) the aggregate principal amount of Securities to be converted, divided by (ii) $1,000, multiplied by (2) the then-applicable
Conversion Rate on the date the converting Holder becomes a record owner of Common Stock pursuant to the last paragraph of Section 4.02(b); 

(B) if the Company elects to satisfy its conversion obligation in respect of such conversion through Cash Settlement, the Company shall pay to
the converting Holder cash in an amount per $1,000 principal amount of Securities being converted equal to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Cash Settlement Averaging Period; and


  
 27 








 (C) if the Company elects to satisfy its conversion obligation in respect of such conversion
through Combination Settlement, the Company shall pay and deliver to the converting Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement Amount equal to the sum of the Daily Settlement
Amounts for each of the 20 consecutive Trading Days during the related Cash Settlement Averaging Period. 
 (6) The “Daily
Settlement Amount” for each of the 20 consecutive Trading Days of the applicable Cash Settlement Averaging Period, will consist of: 

(A) cash equal to the lesser of (i) a dollar amount per Security to be received upon conversion as specified by the Company in the
Settlement Notice (the “Specified Dollar Amount”), if any, divided by 20 (such quotient being referred to as the “Daily Measurement Value”) and (ii) the Daily Conversion Value; and 

(B) to the extent the Daily Conversion Value for such Trading Day exceeds the Daily Measurement Value for such Trading Day, a number of shares
of Common Stock equal to (i) the difference between the Daily Conversion Value and the Daily Measurement Value, divided by (ii) the Daily VWAP of the Common Stock for such Trading Day. 

(7) In the case of Cash Settlement or Combination Settlement, the Settlement Amount shall be determined by the Company promptly following the
last day of the Cash Settlement Averaging Period. Promptly after such determination of the Settlement Amount and the amount of cash deliverable in lieu of fractional shares (if any), the Company shall notify the Trustee and the Conversion Agent of
the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent shall be entitled to rely exclusively on the
notice given by the Company and shall have no responsibility for any such determination. 
 (8) At any time prior to the Final Conversion
Period, the Company may, in its sole discretion and without the consent of the Holders, make an irrevocable Physical Settlement Election. Such Physical Settlement Election shall become effective upon delivery by the Company of a Physical Settlement
Election Notice to the Trustee and each of the Holders. Simultaneously with the giving of such Physical Settlement Election Notice, the Company shall disseminate a press release through Dow Jones & Company, Inc. or Bloomberg Business News
announcing such Physical Settlement Election or publish such information in The Wall Street Journal or another newspaper of general circulation in the City of New York or on the Company’s website. From and after the Physical Election Settlement
Date, the Company shall settle all conversion obligations as though it had elected Physical Settlement in accordance with the provisions of Section 4.03. 

(b) Fractional Shares. Notwithstanding the foregoing, the Company will not issue fractional shares of Common Stock as part of the
Settlement Amount due with respect to any converted Security in respect of which shares of Common Stock are deliverable. Instead, if any such Settlement Amount includes a fraction of a share of Common Stock, the Company will, in lieu of delivering
such fraction of a share of Common Stock, pay an amount of cash equal to the product of (i) such fraction of a share and (ii) the Daily VWAP of the Common Stock on the 

  
 28 








 
relevant Conversion Data (in the case of Physical Settlement) or on the last Trading Day of the applicable Cash Settlement Averaging Period (in the case of Combination Settlement), subject in
each case to the following paragraph. 
 If a Holder surrenders more than one Security for conversion on a single Conversion Date, the
Company will calculate the amount of cash and the number of shares of Common Stock due with respect to such Securities as if such Holder had surrendered for conversion one Security having an aggregate principal amount equal to the sum of the
principal amounts of each of the Securities surrendered for conversion by such Holder on such Conversion Date. 
 (c) Settlement of
Accrued Interest and Deemed Payment of Principal. If a Holder converts a Security, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Security and the Company’s delivery of the amount of
cash and the number of shares of Common Stock, if any, into which a Security is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such
Security to, but excluding, the Conversion Date; provided, however, that if a Holder converts a Security after a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will still
be obligated to pay the interest due on such Interest Payment Date to the Holder of such Security on such Regular Record Date (provided the Holder makes the interest payment upon conversion if so required by Section 4.02(f)). 

As a result, except as otherwise provided in the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect
to a converted Security will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, if the Settlement Amount for any Security includes both cash and shares of the Common Stock, accrued and unpaid interest will be
deemed to be paid first out of the amount of cash delivered upon such conversion. In no event will a Holder be entitled to receive any dividend or other distribution with respect to any Common Stock issued on conversion of such Holder’s
Securities if the applicable Conversion Date is after the Regular Record Date for such dividend or distribution. Prior to the settlement of any conversion in accordance with this Section 4.03, a Holder shall not be the owner of any Common Stock
issuable upon conversion of such Holder’s Securities. 
 (d) Notices. Whenever a Conversion Date occurs with respect to a
Security, the Conversion Agent will (provided it has received a Conversion Notice from the Depository or the Holder), as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the
Company and the Trustee, if it is not then the Conversion Agent, notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Securities converted on such Conversion Date and the names of the
Holders that converted Securities on such Conversion Date. 
 Section 4.04 Adjustment of Conversion Rate. The Conversion
Rate will be adjusted as described in this Section 4.04, except that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of a share split or share combination), at the same time and
upon the same terms as holders of the Common Stock and as 

  
 29 








 
a result of holding the Securities, in any of the transactions described below without having to convert their Securities, as if they held a number of shares of Common Stock equal to the
applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder. 
 (a) If
the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate will be adjusted based on
the following formula: 
  

					
	 CR1
	  	=	  	CR0 x         OS1    
		  		  	                   OS0

 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or combination,
as applicable;
			
	 CR1
	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such effective date;
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date, as applicable, before giving effect to such dividend, distribution, share split or share
combination; and
			
	 OS1
	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.

 Any adjustment made under this Section 4.04(a) shall become effective immediately after the Open of
Business on the Ex-Dividend Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this
Section 4.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution to the Conversion Rate that would then
be in effect if such dividend or distribution had not been declared. 
 (b) If the Company issues to all or substantially all holders of the
Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the
Last Reported Sale Prices of the Common Stock for the 10 

  
 30 








 
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate will be increased based on the
following formula: 
  

					
	CR1	  	=	  	CR0 x         OS0 + X    
		  		  	                   OS0 + Y

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive
Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 4.04(b) will be made successively whenever any such rights, options
or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common
Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or
warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if such rights, options or warrants are not exercised prior to their expiration,
the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. 

For purposes of this Section 4.04(b) and Section 4.01(b)(3) hereof, in determining whether any rights, options or warrants entitle
the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading
Day immediately preceding the date of announcement for such issuance, and in 

  
 31 








 
determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options 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. 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,
options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding: 

(1) dividends or distributions, rights options or warrants as to which an adjustment was effected pursuant to Section 4.04(a) hereof or
Section 4.04(b) hereof; 
 (2) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to
Section 4.04(d) hereof; and 
 (3) Spin-Offs as to which the provisions set forth below in this Section 4.04(c) shall apply; 

then the Conversion Rate shall be increased based on the following formula: 
  

					
	CR1	  	=	  	CR0 x    
        SP0        
		  		  	                SP0 - FMV

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors) of the shares of the Company’s Capital Stock, evidences the Company’s indebtedness, other assets, or property of the Company or rights, options or warrants to
acquire the Company’s Capital Stock or other securities distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

 If “FMV” (as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, each Holder of Securities shall receive, in respect of each $1,000 

  
 32 








 
principal amount of Securities it holds, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Company’s Capital Stock, evidences of the
Company’s indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that such Holder would have received as if such Holder owned a number of shares of
Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. 
 Any increase made under the portion of
this Section 4.04(c) will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared. 
 With respect to an adjustment pursuant to this
Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary of the Company or other
business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a United States national securities exchange (a
“Spin-Off”), the Conversion Rate will be increased based on the following formula: 
  

					
	CR1	  	=	  	CR0 x       FMV0 +
MP0  
		  		  	                        MP0

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such Spin-Off;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period after, and
including, the effective date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(c)
will be made immediately after the Open of Business on the day after the last Trading Day of the Valuation Period, but will be given effect as of the Open of Business on the Ex-Dividend Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off
is less than 10 Trading Days prior to, and including, the end of the Cash Settlement Averaging Period in respect 

  
 33 








 
of any conversion, references within this Section 4.04(c) to 10 Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values in respect of that
conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Cash Settlement Averaging Period. For purposes of determining the
applicable Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 4.04(c) related to “Spin-Offs” to 10 Trading Days
shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the relevant Conversion Date. 

For purposes of the second adjustment set forth in this clause 4.04(c), (i) the Last Reported Sale Price of any Capital Stock or similar
equity interest shall be calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock in the definition of “Last Reported Sale Price” set forth in Section 1.02 hereof, (ii) whether a
day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a
day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based
on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest. 
 Subject to
Section 4.04(g), for the purposes of this Section 4.04(c), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock
(either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock;
(2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this
Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or 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 4.04(c). If any such right, option or warrant, distributed prior to the Issue Date are subject to events, upon the occurrence of which such rights, options 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 Ex-Dividend Date of such deemed distribution (in which case the original rights,
options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options 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 4.04(c) was made, (1) in the
case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, upon such final  

  
 34 








 
redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted
to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to such
rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants
which 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. 

For purposes of Section 4.04(a) hereof, Section 4.04(b) hereof and this Section 4.04(c), if any dividend or distribution to
which this Section 4.04(c) applies includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which
Section 4.04(a) hereof also applies (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights,
options or warrants to which Section 4.04(b) hereof also applies (the “Clause B Distribution”), 
 then (i) such dividend
or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate
adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion
Rate adjustment required by Section 4.04(b) hereof with respect thereto shall then be made, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause B Distribution and the Clause A Distribution, if any,
shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to the
Open of Business on such Ex-Dividend Date” within the meaning of Section 4.04(b) hereof, and (iii) the Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the
case may be, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution, and
(B) any shares of Common Stock included in the Clause A distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date” within the meaning of
Section 4.04(a) hereof. 
 (d) If any cash dividend or distribution is made to all or substantially all holders of the
Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds $0.77 (the “Dividend Threshold Amount”) for such quarter, the Conversion Rate shall be increased based on the
following formula: 
  

					
	CR1	  	=	  	CR0 x       (SP0 - T)  
		  		  	                (SP0 – C)


  
 35 








 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution
			
	T	  	=	  	the dividend threshold amount; and
			
	C	  	=	  	the amount in cash per share that the Company distributes to holders of the Common Stock

 The Dividend Threshold Amount is subject to adjustment on an inversely proportional basis whenever the
Conversion Rate is adjusted other than adjustments made pursuant to this Section 4.04(d). If an adjustment is required to be made as set forth in this Section 4.04(d) as a result of a distribution that is not a regular quarterly dividend,
the Dividend Threshold Amount will be deemed to be zero with respect to that particular adjustment. 
 If “C” (as defined above)
is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Securities it holds, at the
same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for
such cash dividend or distribution. Such increase shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be
decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (e) If
the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds
the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Offer Expiration Date”), the Conversion Rate
shall be increased based on the following formula: 
  

					
	CR1	  	=	  	CR0 x         AC + (SP1 x OS1)    
		  		  	                         OS0 x SP1


  
 36 








 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Close of Business on the Offer Expiration Date;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Close of Business the Offer Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or
exchange in such tender offer or exchange offer);
			
	OS1	  		  	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange
in such tender or exchange offer); and
			
	SP1	  		  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date.

 The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(e)
will be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. If the Trading Day next succeeding the Offer Expiration Date is less than 10 Trading Days prior to, and including, the end of the Cash
Settlement Averaging Period in respect of any conversion, references within this Section 4.04(e) to 10 Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values in respect of that conversion, with
such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the last Trading Day of such Cash Settlement Averaging Period. For purposes of determining the
applicable Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this Section 4.04(e) to 10 Trading Days shall be deemed replaced with
such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the relevant Conversion Date. 

(f) Special Settlement Provisions. Notwithstanding anything to the contrary herein with respect to converted Securities as to
which Combination Settlement is applicable, if a Holder converts a Security and the Daily Settlement Amount for any Trading Day during the Cash Settlement Averaging Period applicable to such Security: 

(1) is calculated based on a Conversion Rate adjusted on account of any event described in Sections 4.04(a) through (e) hereof; and 

(2) includes any shares of Common Stock that, but for this provision, would entitle their holder to participate in such event; 

  
 37 








 then, although the Company will otherwise treat such Holder as the holder of record of such shares of Common
Stock on the last Trading Day of such Cash Settlement Averaging Period, the Company will not permit such Holder to participate in such event on account of such shares of Common Stock. 

In addition, if a Holder converts a Security to which Combination Settlement is applicable and: 

(1) the record date, effective date or Offer Expiration Date for any event that requires an adjustment to the Conversion Rate under any of
Sections 4.04(a) through (e) hereof occurs: 
 (a) on or after the first Trading Day of such Cash Settlement Averaging
Period; and 
 (b) on or prior to the last Trading Day of such Cash Settlement Averaging Period; and 

(2) the Daily Settlement Amount for any Trading Day in such Cash Settlement Averaging Period that occurs on or prior to such record date,
effective date or Offer Expiration Date: 
 (a) includes shares of the Common Stock that do not entitle their holder to
participate in such event; and 
 (b) is calculated based on a Conversion Rate that is not adjusted on account of such event;

 then on account of such conversion, the Company will, on such record date, effective date or Offer Expiration Date, treat such Holder, as a result of
having converted such Securities, as though it were the record holder of a number of shares of Common Stock equal to the total number of shares of Common Stock that: 

(1) are deliverable as part of the Daily Settlement Amount: 

(a) for a Trading Day in such Cash Settlement Averaging Period that occurs on or prior to such record date, effective date or
Offer Expiration Date; and 
 (b) is calculated based on a Conversion Rate that is not adjusted for such event; and 

(2) if not for this provision, would not entitle such Holder to participate in such event. 

  
 38 








 In addition, and notwithstanding anything to the contrary herein, with respect to any Securities
as to which Physical Settlement is applicable, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Securities on or after such Ex-Dividend Date and on or prior to the
related Regular Record Date would be treated as the record holder of shares of Common Stock as of the related Conversion Date in accordance with the provisions of the last paragraph of Section 4.02(b) based on an adjusted Conversion Rate for
such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such Holder will be treated as
if such Holder were the record owners of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

(g) Poison Pill. Whenever a Holder converts a Security, to the extent that the Company has a rights plan in effect, the Holder
converting such Security will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion, the rights under the rights plan unless the rights have separated from the Common Stock, in which case, and only
in such case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as
described in Section 4.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such rights. 

(h) Deferral of Adjustments. Notwithstanding anything to the contrary herein, except on and after the first Trading Day of any
Cash Settlement Averaging Period with respect to a Security and on or prior to the last Trading Day of such Cash Settlement Averaging Period, the Company will not be required to adjust the Conversion Rate unless such adjustment would require an
increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and provided,
further, that any such adjustment of less than one percent that has not been made shall be made upon the occurrence of (i) the Effective Date for any Make-Whole Fundamental Change, (ii) the first Trading Day of any Cash Settlement
Averaging Period and (iii) if the Company elects to satisfy its conversion obligation solely in shares of Common Stock, upon any conversion of Securities. In addition, the Company shall not account for such deferrals when determining whether
any of the conditions to conversion have been satisfied or what number of shares of Common Stock a Holder would have held on a given day had it converted its Securities. 

(i) Limitation on Adjustments. Except as stated in this Section 4.04, the Company will not adjust the Conversion Rate for
the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. If, however, the application of
the formulas in Sections 4.04(a) through (e) hereof would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a
result of a reverse share split, share combination or readjustment). 

  
 39 








 In addition, notwithstanding anything to the contrary herein, the Conversion Rate will not be
adjusted: 
 (1) on account of stock repurchases that are not tender offers referred to in Section 4.04(e) hereof, including structured
or derivative transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors or otherwise; 
 (2)
upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of
Common Stock under any plan; 
 (3) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant
to any present or future employee, director or consultant benefit plan, program or agreement of or assumed by the Company or any of its Subsidiaries; 

(4) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in the preceding clause (3) and outstanding as of the date the Securities were first issued; 
 (5) for a change
in the par value of the Common Stock; 
 (6) for accrued and unpaid interest on the Securities, if any; or 

(7) for an event otherwise requiring an adjustment under this Indenture if such event is not consummated. 

(j) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the
treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock 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. 
 Section 4.05 Discretionary and Voluntary Adjustments. 

(a) Discretionary Adjustments. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale
Prices, the Daily VWAPs or any function thereof over a span of multiple days (including during a Cash Settlement Averaging Period), the Company will make appropriate adjustments to each to account for any adjustment to the Conversion Rate that
becomes effective, or any event requiring an adjustment to the Conversion Rate where the Effective Date, Ex-Dividend Date or Offer Expiration Date of the event occurs, at any time during the period when such Last Reported Sale Prices, the Daily
VWAPs or function thereof is to be calculated. 

  
 40 








 (b) Voluntary Adjustments. To the extent permitted by applicable law, the Company
is permitted to increase the Conversion Rate of the Securities by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. The Company may also (but is
not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar
event. 
 Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change.

 (a) Increase in the Conversion Rate. If a Make-Whole Fundamental Change occurs and a Holder elects to convert its
Securities in connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, increase the Conversion Rate for the Securities so surrendered for conversion by a number of additional shares of Common Stock (the
“Additional Shares”), as described in this Section 4.06. A conversion of Securities shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the relevant
Conversion Notice is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on the Business Day immediately prior to the related
Fundamental Change Purchase Date or, if such Make-Whole Fundamental Change is not a Fundamental Change, the 35th Business Day immediately following the Effective Date for such Make-Whole Fundamental Change. 

(b) Cash Mergers. Notwithstanding anything to the contrary herein, if the consideration paid to holders of the Common Stock in
any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is comprised entirely of cash, then, for any conversion of Securities following the Effective Date of such Make-Whole Fundamental Change, the
payment and delivery obligations upon the conversion of a Security shall be calculated based solely on the Stock Price for such Make-Whole Fundamental Change and shall, for each $1,000 principal amount of Securities converted, be deemed to be an
amount of cash equal to the product of (i) the Conversion Rate in effect on the applicable Conversion Date (as increased by any number of Additional Shares required by this Section 4.06) multiplied by (ii) such Stock Price. In
such event, the Company will pay such amount of cash to a converting Holder on the third Business Day following the applicable Conversion Date. Otherwise, the Company will settle any conversion of the Securities following the Effective Date for a
Make-Whole Fundamental Change in accordance with Section 4.02 hereof (but subject to Section 4.07 hereof). 
 (c)
Determining the Number of Additional Shares. The number of Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Securities in connection with a Make-Whole Fundamental Change shall be
determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the
“Stock Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change 


  
 41 








 
described in clause (2) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported
Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. 

(d) Interpolation and Limits. The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A,
in which case: 
 (1) If the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective
Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as
applicable, based on a 365-day year. 
 (2) If the Stock Price is greater than $130.00 per share (subject to adjustment in the same manner
as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased. 

(3) If the Stock Price is less than $59.84 per share (subject to adjustments in the same manner as the Stock Prices set forth in the column
headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased. 

Notwithstanding the foregoing, in no event will the Conversion Rate be increased on account of a Make-Whole Fundamental Change to exceed
16.7112 shares of Common Stock per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04 hereof. 

(4) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be adjusted as of any date on which the
Conversion Rate of the Securities is otherwise required to be adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner and
at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04. 
 (e) Notices. The
Company shall notify the Holders of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. 

(a) Merger Events. In the case of: 

(1) any recapitalization, reclassification or change of the Common Stock (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a split, subdivision or combination for which an adjustment was made pursuant to Section 4.04(a) hereof); 

  
 42 








 (2) any consolidation, merger or combination involving the Company; 

(3) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an
entirety; or 
 (4) any statutory share exchange; 

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets
(including cash or any combination thereof) (any such event, a “Merger Event,” any such stock, other securities, other property or assets, “Reference Property,” and the amount of kind of Reference Property that a
holder of one share of Common Stock (i) is entitled to receive in the applicable Merger Event or (ii) if as a result of the applicable Merger Event, each share of Common Stock is converted into the right to receive more than a single type
of consideration (determined based in part upon any form of stockholder election), the per-share of Common Stock weighted average of the types and amounts of Reference Property received by the holders of Common Stock that affirmatively make such an
election, a “Unit of Reference Property”) then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities based on a number of shares of the Common Stock equal to the applicable
Conversion Rate will, without the consent of the Holders, be changed into a right to convert each $1,000 principal amount of Securities based on a number of Units of Reference Property equal to the applicable Conversion Rate and, prior to or at the
effective time of such Merger Event, 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 such change in the right to convert each $1,000 principal amount of Securities; provided, however, that (i) any amount payable in cash upon conversion of
the Securities in accordance with Sections 4.03 and 4.06 hereof shall continue to be payable in cash, (ii) the number of shares of Common Stock that the Company would have been required to deliver upon conversion of the Securities in accordance
with Sections 4.03 and 4.06 hereof shall instead be deliverable in Units of Reference Property and (iii) the Daily VWAP and the Last Reported Sale Price will, to the extent reasonably possible, be calculated based on the value of a Unit of
Reference Property and the definitions of Trading Day and Market Disruption Event shall be determined by reference to the components of a Unit of Reference Property. 

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election) as contemplated by the preceding paragraph such that a Unit of Reference Property is comprised of the per-share of Common Stock weighted average of the types and amounts
of consideration received by the holders of the Common Stock in the Merger Event that affirmatively make such an election, the Company shall notify Holders of the weighted average as soon as practicable after such determination is made. 

  
 43 








 The Company shall not become a party to any Merger Event unless its terms are consistent with
this Section 4.07. Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the
Board of Directors or the board of directors of the successor person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets
(including cash or any combination thereof) of a person other than the successor or purchasing person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other person. 

(b) Notice of Supplemental Indentures. The Company shall cause notice of the execution of such supplemental indenture to be
mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Security Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events. 

Section 4.08 Stock Issued Upon Conversion. 

(a) Reservation of Shares. To the extent necessary to satisfy its obligations under this Indenture, prior to issuing any shares
of Common Stock, the Company will reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Securities. 

(b) Certain other Covenants. The Company covenants that all shares of Common Stock that may be issued upon conversion of
Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the
Holder or due to a change in registered owner). 
 The Company shall list or cause to have quoted any shares of Common Stock to be
issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 

Section 4.09 Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or
responsibility to any Holder of Securities to determine or calculate the Conversion Rate, to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or
the appropriateness of 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 other securities or property that may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and the 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 

  
 44 








 
Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections,
immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its
capacity as Conversion Agent. 
 Section 4.10 Notice to Holders. 

(a) Notice to Holders Prior to Certain Actions. The Company shall deliver notices of the events specified below at the times
specified below and containing the information specified below unless, in each case, (i) pursuant to this Indenture, the Company is already required to deliver notice of such event containing at least the information specified below at an
earlier time or, (ii) the Company, at the time it is required to deliver a notice, does not have knowledge of all of the information required to be included in such notice, in which case, the Company shall (A) deliver notice at such time
containing only the information that it has knowledge of at such time (if it has knowledge of any such information at such time), and (B) promptly upon obtaining knowledge of any such information not already included in a notice delivered by
the Company, deliver notice to each Holder containing such information. In each case, the failure by the Company to give such notice, or any defect therein, shall not affect the legality or validity of such event. 

(1) Issuances, Distributions, and Dividends and Distributions. If the Company (A) announces any issuance of any rights,
options or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04(b) hereof; (B) authorizes any distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(c) hereof
(including any separation of rights from the Common Stock described in Section 4.04(g) hereof); or (C) announces any dividend or distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(d) hereof,
then the Company shall deliver to the Holders, as promptly as possible, but in any event at least 15 calendar days prior to the applicable Ex-Dividend Date, notice describing such issuance, distribution, dividend or distribution, as the case may be,
and stating the expected Ex-Dividend Date and record date for such issuance, distribution, dividend or distribution, as the case may be. In addition, the Company shall deliver to the Holders notice if the consideration included in such issuance,
distribution, dividend or distribution, or the Ex-Dividend Date or record date of such issuance, distribution, dividend or distribution, as the case may be, changes. 

(2) Voluntary Increases. If the Company increases the Conversion Rate pursuant to Section 4.05(b), the Company shall
deliver notice to the Holders at least 15 calendar days prior to the date on which such increase will become effective, which notice shall state the date on which such increased will become effective and the amount by which the Conversion Rate will
be increased. 
 (3) Dissolutions, Liquidations and Winding-Ups. If there is a voluntary or involuntary dissolution,
liquidation or winding-up of the Company, the Company shall deliver notice to the Holders at promptly as possible, but in any event at least 15 calendar days prior to the earlier of (i) the date on which such dissolution, liquidation or
winding-up, as the case may 

  
 45 








 
be, is expected to become effective or occur, and (ii) 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 dissolution, liquidation or winding-up, as the case may be, which notice shall state the expected effective date and record date for such event, as applicable, and the amount and kind of property
that a holder of one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company shall deliver an additional notice to holders, as promptly as practicable, whenever the expected effective date or record
date, as applicable, or the amount and kind of property that a holder of one share of the Common Stock is expect to be entitled to receive in such event, changes. 

(b) Notices After Certain Actions and Events. Whenever an adjustment to the Conversion Rate becomes effective pursuant to
Sections 4.04, 4.05 or 4.06 hereof, the Company will (i) file with the Trustee an Officers’ Certificate stating that such adjustment has become effective, the Conversion Rate, and the manner in which the adjustment was computed and
(ii) deliver notice to the Holder’s stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to give any such notice, or any defect therein, shall not affect the validity of any
such adjustment. 
 ARTICLE 5 

PARTICULAR COVENANTS OF THE COMPANY 

Section 5.01 Inapplicable Covenants Made in the Base Indenture. The Holders will not have the benefit of the Covenants set forth
in Section 1008 of the Base Indenture. 
 Section 5.02 Payment of Principal, Interest and Fundamental Change Purchase
Price. This Section 5.02 shall replace Section 1001 of the Base Indenture in its entirety. 
 The Company covenants and agrees
that it will cause to be paid the principal of (including the Fundamental Change Purchase Price), and accrued and unpaid interest, if any, on each of the Securities at the places, at the respective times and in the manner provided herein and in the
Securities. 
 Section 5.03 Maintenance of Office or Agency. This Section 5.03 replaces Section 1002 of the Base
Indenture in its entirety and references in the Base Indenture to Section 1002 of the Base Indenture shall be deemed replaced with references to this Section 5.03. 

The Company will maintain in the Borough of Manhattan, The City of New York, an office of the Paying Agent, an office of the Security
Registrar and an office or agency where Securities may be surrendered for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 

  
 46 








 The Company may also from time to time designate coregistrars one or more other offices or
agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of
any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 

The Company hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian, Conversion Agent and the Corporate
Trust Office, which shall be in the continental United States, shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 

With respect to any Global Security, the Corporate Trust Office of the Trustee or any Paying Agent shall be the Place of Payment where
such Global Security may be presented or surrendered for payment or conversion or for registration of transfer or exchange, or where successor Securities may be delivered in exchange therefor; provided, however, that any such payment,
conversion, presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depository for such Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with the
provisions of this Indenture. 
 Section 5.04 Appointments to Fill Vacancies in Trustee’s Office. The Company,
whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 608 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 5.05 Provisions as to Paying Agent. This Section 5.05 shall replace Section 1003 of the Base Indenture in its
entirety and references in the Base Indenture to Section 1003 of the Base Indenture shall be deemed replace with references to this Section 5.05. 

(a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.05: 
 (1) that it
will hold all sums held by it as such agent for the payment of the principal of, accrued and unpaid interest, if any, on, and the Fundamental Change Purchase Price for, the Securities in trust for the benefit of the holders of the Securities; 

(2) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal of, accrued and unpaid
interest, if any, on, or the Fundamental Change Purchase Price for, the Securities when the same shall be due and payable; and 
 (3) that
at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 

  
 47 








 The Company shall, one Business Day prior to each due date of the principal of, accrued and
unpaid interest, if any, on, and Fundamental Change Purchase Price for, the Securities, deposit with the Paying Agent a sum sufficient to pay such principal, accrued and unpaid interest, or Fundamental Change Purchase Price, as the case may be, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action. 
 (b) If the
Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price for, the Securities, set aside, segregate and hold in trust for the
benefit of the holders of the Securities a sum sufficient to pay such principal, accrued and unpaid interest, if any, on or Fundamental Change Purchase Price, as the case may be, so becoming due and will promptly notify the Trustee in writing of any
failure to take such action and of any failure by the Company to make any payment of the principal of, accrued and unpaid interest on, or Fundamental Change Purchase Price for, the Securities when the same shall become due and payable. 

(c) Anything in this Section 5.05 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a
satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 5.05, such sums to be held by the
Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums. 

Section 5.06 Reports. This Section 5.06 will replace Section 703 of the Base Indenture in its entirety. 

The Company will file with the Trustee, within 15 days after it is required to file the same with the SEC, copies of the quarterly and annual
reports and of the information, documents and other reports, if any, that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and to otherwise comply with Section 314(a) of the Trust Indenture Act. Any
such report, information or document that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be delivered to the Trustee for the purposes of this Section 5.06 at the time of such filing through
the EDGAR system (or such successor thereto). 
 Delivery of any such reports, information and documents to the Trustee shall be for
informational purposes only, and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 

  
 48 








 Section 5.07 Statements as to Defaults. The Company shall deliver to the Trustee, as
soon as possible, and in any event within thirty days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default, its status and
the action that the Company proposes to take with respect thereto. Such Officers’ Certificate shall also comply with any additional requirements set forth in Section 102 of the Base Indenture. 

Section 5.08 Supplementary Interest Notice. If Supplementary Interest is payable by the Company pursuant to Section 6.04
hereof, the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount of such Supplementary Interest that is payable and (b) the date on which such interest is payable. Unless and until a
Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Supplementary Interest is payable. If the Company has paid Supplementary Interest directly to the
Persons entitled to them, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 

Section 5.09 Covenant to Take Certain Actions. Before taking any action which would cause an adjustment to the Conversion Rate
such that the Conversion Price per share of Common Stock issuable upon conversion of the Securities would be less than the par value of the Common Stock, the Company shall take all corporate actions that may, in the opinion of its counsel, be
necessary so it may validly and legally issue shares of Common Stock at such adjusted Conversion Rate.

 49 








 (e) Each reference in the Base Indenture to Section 502 is, with respect to the Securities,
hereby deemed replaced by a reference to Section 6.03 hereof. 
 (f) Section 602 of the Base Indenture is amended with respect to
the Securities to add the following sentence immediately following the last sentence of Section 602: “In the event an Event of Default has occurred and is continuing, the Trustee shall be required in the exercise of its powers under the
Indenture to use the degree of care that a prudent person would use in the conduct of its own affairs.” 
 Section 6.02 Events
of Default. Each of the following events (and only the following events) shall be an “Event of Default” wherever used with respect to the Securities: 

(a) default in any payment of interest on any Security when due and payable, and the default continues for a period of thirty days; 

(b) default in the payment of the principal of any Security (including the Fundamental Change Purchase Price) when due and payable on the
Maturity Date, upon required repurchase, upon declaration of acceleration or otherwise; 
 (c) failure by the Company to comply with its

 (f) failure by the Company for 60 days after written notice from the Trustee or the Holders of at least 25% in principal
amount of the Securities then Outstanding (a copy of which notice, if given by Holders, must also be given to the Trustee) has been received by the Company to comply with any of its other agreements contained in the Securities or this Indenture
(other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section 6.02 specifically provided for or that is not applicable to the Securities), which notice shall state that it is a “Notice of
Default” hereunder; 
 (g) failure by the Company to pay beyond any applicable grace period, or the acceleration of, indebtedness
of the Company or any of the Company’s Subsidiaries in an aggregate amount greater than $10,000,000 (or its foreign currency equivalent at the time); 

(h) the Company or any Significant Subsidiary of the Company shall commence a voluntary case or other proceeding seeking the liquidation,
reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator,
custodian or other similar official of the Company or such Significant 

  
 50 








 
Subsidiary of the Company or any substantial part of the Company’s or such Significant Subsidiary of the Company’s property, or shall consent to any such relief or to the appointment of
or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or 

(i) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary of the Company seeking
liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary of the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a
trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary of the Company or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and
unstayed for a period of thirty consecutive days. 
 Section 6.03 Acceleration; Rescission and Annulment. If one or more Events
of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any
order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(h) or Section 6.02(i) with respect to the Company (and not solely with
respect to a Significant Subsidiary of the Company)), unless the principal of all of the Securities shall have already become due and payable, either the Trustee or the holders of at least 25% in aggregate principal amount of the Securities then
Outstanding, by notice in writing to the Company (and to the Trustee if given by the Holders), may declare 100% of the principal of, and accrued and unpaid interest, if any, on all the Securities to be due and payable immediately. If an Event of
Default specified in Section 6.02(h) or Section 6.02(i) with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company) occurs and is continuing, the principal of, and accrued and unpaid interest, if
any, on all Securities shall be immediately due and payable. 
 Section 6.04 Supplementary Interest. 

(a) Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default
relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that it is required to file with the Commission pursuant to Section 13 or 15(d) of
the Exchange Act, or (ii) the Company’s failure to comply with Section 5.06 hereof (a “Reporting Event of Default”), will consist exclusively of the right to receive additional interest on the Securities (the
“Supplementary Interest”) at a rate per year equal to (i) 0.25% per annum of the Outstanding principal amount of the Securities for the first 90 days of the 180-day period on which such Event of Default is continuing
beginning on, and including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum of the Outstanding principal amount of the Securities for the last 90 days of such 180-day period as long as such Event of
Default is continuing. If the Company so elects, such Supplemental Interest will be payable in the same manner and on the same dates as the stated interest payable on the Securities. On the 181st day


  
 51 








 
after such Event of Default (if the Reporting Event of Default is not cured or waived prior to such 181st day), the Securities will be subject to acceleration pursuant to Section 6.03. The
provisions of this Section 6.04 will not affect the rights of Holders of Securities in the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Company does not elect to pay the Supplemental
Interest following an Event of Default in accordance with this Section 6.04 or the Company elected to make such payment but do not pay the Supplemental Interest when due, the Securities will be immediately subject to acceleration as provided in
Section 6.03. 
 (b) In order to elect to pay the Supplemental Interest as the sole remedy during the first 180 days after the
occurrence of an Reporting Event of Default, the Company must notify all Holders of Securities, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the Company’s failure to timely give such
notice, the Securities will be immediately subject to acceleration as provided in Section 6.03. 
 Section 6.05 Waiver of Past
Defaults. The Holders of a majority in aggregate principal amount of the Securities then Outstanding, by written notice to the Company and to the Trustee, may waive (including by way of consents obtained in connection with a repurchase of, or
tender or exchange offer for, the Securities) all past Defaults or Events of Default with respect to the Securities (other than a Default or an Event of Default resulting from nonpayment of principal or interest, a failure to deliver consideration
due upon conversion or any other provisions that requires the consent of each affected Holder to amend) and rescind any such acceleration with respect to the Securities and its consequences if (i) rescission would not conflict with any judgment
or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of, and interest on, the Securities that have become due solely by such declaration of acceleration have been
cured or waived. 
 Section 6.06 Control by Majority. At any time, the Holders of a majority of the aggregate principal amount
of the then Outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow
any direction that conflicts with law or this Indenture or, subject to the Trustee’s duties under Article 6 of the Base Indenture and the Trust Indenture Act, that the Trustee determines to be unduly prejudicial to the rights of a Holder
or to the Trustee, or that would potentially involve the Trustee in personal liability unless the Trustee is offered indemnity or security reasonably satisfactory to it against any loss, liability or expense to the Trustee that may result from the
Trustee’s instituting such proceeding as the Trustee. Prior to taking any action hereunder, the Trustee will be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such
action. 
 Section 6.07 Limitation on Suits. Subject to Section 6.08 hereof, no Holder may pursue a remedy with respect to
this Indenture or the Securities unless: 
 (a) such Holder has previously delivered to the Trustee written notice that an Event of Default
has occurred and is continuing; 

  
 52 








 (b) the Holders of at least 25% of the aggregate principal amount of the then Outstanding
Securities deliver to the Trustee a written request that the Trustee pursue a remedy with respect to such Event of Default; 
 (c) such
Holder or Holders have offered and, if requested, provided to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or other expense of compliance with such written request; 

(d) the Trustee has not complied with such written request within 60 days after receipt of such written request and offer of indemnity; and

 (e) during such 60-day period, the Holders of a majority of the aggregate principal amount of the then Outstanding Securities did not
deliver to the Trustee a direction inconsistent with such written request. 
 A Holder may not use this Indenture to prejudice the rights of
any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of this Indenture by a Holder is unduly prejudicial to such other
Holders. 
 Section 6.08 Rights of Holders to Receive Payment and to Convert. Notwithstanding anything to the contrary elsewhere
in this Indenture, the right of any Holder to receive payment of the principal of, interest on, Fundamental Change Purchase Price for, its Securities, on or after the respective due date, and to convert its Securities and receive payment or delivery
of the consideration due with respect to such Securities in accordance with Article 4 hereof, or to bring suit for the enforcement of any such payment or conversion rights, will not be impaired or affected without the consent of such Holder and will
not be subject to the requirements of Section 6.07 hereof. 
 Section 6.09 Collection of Indebtedness; Suit for Enforcement by
Trustee. If an Event of Default specified in Section 6.02(a), 6.02(b) or 6.02(c) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the
whole amount of principal of, interest on, Fundamental Change Purchase Price for, and the amount of cash or the combination of cash and shares of Common Stock, if any, as the case may be, due upon the conversion of, the Securities, as the case may
be, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be
due under Section 606 of the Base Indenture. 
 Section 6.10 Trustee May Enforce Claims Without Possession of Securities.
All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such
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 in respect of which such judgment has been recovered. 

  
 53 








 Section 6.11 Trustee May File Proofs of Claim. The Trustee is authorized to file such
proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law
or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under Section 606 of the Base Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 606 of the Base Indenture out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is paid out of, any and all
distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be
deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.12 Restoration of Rights and
Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 Section 6.13 Rights and
Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 306 of the Base Indenture, no right or remedy herein conferred upon or reserved to
the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 6.14 Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence 

  
 54 








 
therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee
(subject to the limitations contained in this Indenture) or by the Holders, as the case may be. 
 Section 6.15 Priorities. If
the Trustee collects any money pursuant to this Article 6, it will pay out the money in the following order: 
 FIRST: to the Trustee, its
agents and attorneys for amounts due under Section 606 of the Base Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, Fundamental Change Purchase Price
for, and any cash due upon conversion of, any Security, without preference or priority of any kind, according to such amounts due and payable on all of the Securities; and 

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs. 

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.15. If the Trustee so fixes
a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment. 

Section 6.16 Undertaking for Costs. All parties to this Indenture agree, and each Holder, by such Holder’s acceptance of a
Security, 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, 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, however, that the provisions of this Section 6.16 shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of,
accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price for, any Security on or after the due date expressed or provided for in this Indenture or to any suit for the enforcement of the right to convert any Security in
accordance with the provisions of Article 4 hereof. 
 Section 6.17 Waiver of Stay, Extension and Usury Laws. The Company
covenants that, to the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time
hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company, to the extent that it may lawfully do so, hereby 

  
 55 








 
expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the
Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted. 
 Section 6.18
Notices from the Trustee. Notwithstanding anything to the contrary in the Base Indenture, including Section 601 of the Base Indenture, and subject to Section 602(10) of the Base Indenture, whenever a Default or an Event of Default
occurs and is continuing and is known to the Trustee, the Trustee must deliver notice of such Default or Event of Default to the Holders within 90 days after the date on which such Default or Event of Default first occurred. Except in the case of a
Default in the payment of the principal of, interest on, or Fundamental Change Purchase Price for, any Security or of a Default in the payment or delivery, as the case may be, of the consideration due upon conversion of a Security, the Trustee shall
be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in
the interests of the Holders. 
 ARTICLE 7 

SATISFACTION AND DISCHARGE 

Section 7.01 Inapplicability of Provisions of Base Indenture; Satisfaction and Discharge of the Indenture. Article 14 of the Base
Indenture shall not apply with respect to the Securities. The provisions set forth in this Article 7 shall, with respect to the Securities, supersede in their entirety Article 4 of the Base Indenture. 

When (a) the Company shall deliver to the Security Registrar for cancellation all Securities theretofore authenticated (other than any
Securities that have been destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Securities not theretofore canceled or
delivered to the Trustee for cancellation shall have become due and payable (whether on the Maturity Date, on any Fundamental Change Purchase Date, upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to
the Holders, as applicable, an amount of cash or the combination of cash and shares of Common Stock, if any, as the case may be (solely to settle amounts due with respect to outstanding conversions), sufficient to pay all amounts due on all of such
Securities (other than any Securities that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) not theretofore canceled or delivered to the
Trustee for cancellation, including principal and interest due, accompanied, except in the event the Securities are due and payable solely in cash at the Maturity Date or upon an earlier Fundamental Change Purchase Date, by a verification report as
to the sufficiency of the deposited amount from an independent certified accountant or other financial professional reasonably 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 (i) rights hereunder of Holders to receive all amounts owing upon the Securities and the other rights, duties and obligations of Holders, as beneficiaries hereof
with respect to the amounts, if any, so 

  
 56 








 
deposited with the Trustee and (ii) 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 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs
or expenses thereafter reasonably and properly incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this
Indenture or the Securities. 
 Section 7.02 Deposited Monies to Be Held in Trust by Trustee. Subject to Section 7.04
hereof, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 7.01 hereof shall be held in trust for the sole benefit of the Holders of the Securities, and such monies and shares of Common Stock 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 Securities for the payment or settlement of which such monies or shares of
Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any. 

Section 7.03 Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies and shares of
Common Stock, if any, then held by any Paying Agent (if 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 and shares of Common Stock. 
 Section 7.04 Return of Unclaimed Monies. Subject to the requirements of
applicable law, any monies and shares of Common Stock deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Securities and not applied but remaining unclaimed by the Holders of the Securities for two years
after the date upon which the principal of or interest, if any, on such Securities, 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 shares of Common Stock; and the Holder shall thereafter look only to the Company for any payment or delivery that such Holder may be entitled to collect unless an applicable abandoned property law designates
another person. 
 Section 7.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of
Common Stock in accordance with Section 7.02 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 the Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with
Section 7.02; provided, however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Security following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent. 

  
 57 








 ARTICLE 8 

SUPPLEMENTAL INDENTURES 

Section 8.01 Supplemental Indentures Without Consent of Holders. Section 901 of the Base Indenture shall not apply with
respect to the Securities, and this Section 8.01 shall replace Section 901 of the Base Indenture in its entirety. 
 Without the
consent of any Holder, the Company (when authorized by a Board Resolution) and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following
purposes: 
 (a) to conform the terms of this Indenture or the Securities to the description thereof in the Preliminary Prospectus
Supplement, as supplemented by the issuer free writing prospectus related to the offering of the Securities filed by the Company with the Commission pursuant to Rule 433 under the Securities Act of 1933 on March 20, 2014; 

(b) to evidence the succession by a Successor Company and to provide for the assumption by a Successor Company of the Company’s
obligations under the Indenture; 
 (c) to add guarantees with respect to the Securities; 

(d) to secure the Securities; 

(e) to add to the Company’s covenants such further covenants, restrictions or conditions for the benefit of the Holders (or any other
holders) or surrender any right or power conferred upon the Company by the Indenture; 
 (f) to cure any ambiguity, omission, defect or
inconsistency in this Indenture or the Securities, including to eliminate any conflict with the Trust Indenture Act, or to make any other change that does not adversely affect the rights of any Holder in any material respect; 

(g) to provide for a successor Trustee; 

(h) to comply with the Applicable Procedures of the Depository; or 

(i) to comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act. 

Section 8.02 Supplemental Indentures With Consent of Holders. Section 902 of the Base Indenture shall not apply with respect
to the Securities, and this Section 8.02 shall replace Section 902 of the Base Indenture in its entirety. 
 With the consent of
the Holders of not less than a majority in principal amount of the Outstanding Securities affected by such supplemental indenture, including without limitation, consents obtained in connection with a purchase of, or tender or exchange offer for,
Securities 

  
 58 








 
and by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may 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 of modifying in any manner the rights of the Holders under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby: 
 (a) reduce the
percentage in aggregate principal amount of Securities Outstanding necessary to waive any past Default or Event of Default; 
 (b) reduce
the rate of interest on any Security or change the time for payment of interest on any Security; 
 (c) reduce the principal of any Security
or change the Maturity Date; 
 (d) change the place or currency of payment on any Security; 

(e) make any change that impairs or adversely affects the conversion rights of any Securities; 

(f) reduce the Fundamental Change Purchase Price of any Security or amend or modify in any manner adverse to the rights of the Holders of the
Securities the Company’s obligation to pay the Fundamental Change Purchase Price, whether through an amendment or waiver of provisions in the covenants, definitions related thereto or otherwise; 

(g) impair the right of any Holder of Securities to receive payment of principal of, and interest, if any, on, its Securities, or the right to
receive payment of the amount of cash or the combination of cash and shares of Common Stock, if any, as the case may be, due upon conversion of its Securities on or after the due dates therefore or to institute suit for the enforcement of any such
payment or delivery, as the case may be, with respect to such Holder’s Securities; 
 (h) modify the ranking provisions of this
Indenture in a manner that is adverse to the rights of the Holders of the Securities; or 
 (i) make any change to the provisions of this
Article 8 that requires each Holder’s consent or in the waiver provisions in Section 6.05 of this Supplemental Indenture if such change is adverse to the rights of Holders of the Securities. 

It shall not be necessary for any Act or consent of Holders under this Section 8.02 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such Act or consent shall approve the substance thereof. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; 

  
 59 








 
provided that, unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any
such consent previously given shall automatically and without further action by any Holder be cancelled and of no further effect. 

Section 8.03 Notice of Amendment or Supplement. After an amendment or supplement under this Article 8 becomes effective, the
Company shall mail to the Holders a notice briefly describing such amendment or supplement. However, the failure to give such notice to all the Holders, or any defect in the notice, shall not impair or affect the validity of the amendment or
supplement. 
 ARTICLE 9 

SUCCESSOR COMPANY 

Section 9.01 Consolidation, Merger and Sale of Assets. 

(a) The provisions in Articles 8 of the Base Indenture shall not apply with respect to the Securities, and this Article 9 supersedes the
entirety thereof. 
 (b) In addition, the reference to “Article Eight” in Section 1004 of the Base Indenture is, with respect
to the Securities, deemed replaced with a reference to this Article 9. 
 Section 9.02 Company May Consolidate, Etc. on Certain
Terms. Subject to the provisions of Section 9.04, the Company shall not amalgamate or consolidate with, merge with or into or convey, transfer or lease its properties and assets substantially as an entirety to another Person, unless: 

(a) the Company shall be the surviving Person or the resulting, surviving or transferee Person (the “Successor Company”), if
not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental
indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all of the obligations of the Company under the Securities and this Indenture as applicable to the Securities; and 

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this
Indenture. 
 Section 9.03 Successor Corporation to Be Substituted. In case of any such amalgamation, consolidation, merger,
conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of (including
any Fundamental Change Purchase Price), accrued and unpaid interest and accrued and unpaid Supplementary Interest, if any, on all of the Securities, the due and punctual delivery or payment, as the case may be, of any consideration due upon

punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company under this Indenture, such Successor Company shall succeed to and be substituted for,
and may exercise every right and power of, the Company under this Indenture, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own
name or in the name of the Company any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company 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 Securities that previously shall have been signed and delivered by
the officers of the Company to the Trustee for authentication, and any Securities that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have
the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event
of any such amalgamation, consolidation, merger, conveyance or transfer (but not in the case of a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in
the manner prescribed in this Article 9 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Securities and from its
obligations under this Indenture. 
 In case of any such amalgamation, consolidation, merger, conveyance, transfer or lease, such changes in
phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate. 

Section 9.04 Opinion of Counsel to Be Given to Trustee. In the case of an such amalgamation, merger, consolidation, conveyance,
transfer or lease the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel stating that any such amalgamation, consolidation, merger, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 9.

Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded,
the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. 
 Section 10.05
Benefits of Supplemental Indenture. Notwithstanding anything to the contrary in Section 110 of the Base Indenture, nothing in this Supplemental Indenture or in the Securities, expressed or implied, will give to any Person, other than the
parties hereto, any Paying Agent, any Conversion Agent, any Authenticating Agent, any Security Registrar or their successors hereunder or the Holders of the Securities, any benefit or any legal or equitable right, remedy or claim under this

each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder upon the request
of that Holder at the sole cost and expense of the Company. 
 Whenever the Company is required to calculate the Conversion Rate, the
Company will do so to the nearest 1/10,000th of a share of Common Stock. 
 Section 10.07 Execution in Counterparts. This
Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument.

 62 








 
date it is required to deliver such notice to the Holders, deliver a copy of such notice to the Trustee, the Paying Agent, the Security Registrar and the Conversion Agent. Each notice to the
Trustee, the Paying Agent, the Security Registrar and the Conversion Agent shall be sufficiently given if in writing and mailed, first-class postage prepaid to the address most recently sent by the Trustee, the Paying Agent, the Security Registrar
or the Conversion Agent, as the case may be, to the Company. 
 Section 10.09 Ratification of Base Indenture. The Base
Indenture, as supplemented by this Supplemental Indenture, is in all respects ratified and confirmed, and this Supplemental Indenture shall be deemed part of the Base Indenture in the manner and to the extent herein provided. For the avoidance of
doubt, each of the Company and each Holder of Securities, by its acceptance of such Securities, acknowledges and agrees that all of the rights, privileges, protections, immunities and benefits afforded to the Trustee under the Base Indenture are
deemed to be incorporated herein, and shall be enforceable by the Trustee hereunder, in each of its capacities hereunder as if set forth herein in full.

all of the provisions contained in the Base Indenture in respect of the rights, privileges, immunities, powers and duties of the Trustee shall be applicable in respect of the Securities and of this Supplemental Indenture as fully and with like
effect as if set forth in full herein. 
 Section 10.11 No Recourse Against Others. No director, officer, employee, incorporator
or stockholder of the Company shall have any liability for any obligations of the Company under the Securities, the Indenture or any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a
Security, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.

Senior Debt Indenture dated as of March 25, 2014 (herein called the “Base Indenture”), as further supplemented by the First Supplemental Indenture, dated as of March 25, 2014 (herein called the “Supplemental
Indenture” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”) by and between the Company and The Bank of New York Mellon Trust Company, herein called the “Trustee”, and
reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are,
and are to be, authenticated and delivered. This Security is not subject to redemption at the option of the Company prior to the Maturity Date and does not benefit from a sinking fund. 

As provided in and subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change, the Holder of this Security will
have the right, at such Holder’s option, to require the Company to purchase this Security, or any portion of this Security such that the principal amount of this Security that is not purchased equals $1,000 or an integral multiple of $1,000 in
excess thereof, on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price for such Fundamental Change Purchase Date. 

As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at its option (i) during certain periods
and upon the occurrence of certain conditions specified in the Indenture, prior to the Close of Business on the Business Day immediately preceding October 1, 2020, and (ii) on or after October 1, 2020, at any time prior to the Close
of Business on the second Scheduled Trading Day immediately preceding the Stated Maturity, to convert this Security or a portion of this Security such that the principal amount of this Security that is not converted equals $1,000 or an integral
multiple of $1,000 in excess thereof, into an amount of cash, shares of Common Stock or a combination of cash and shares of Common Stock, as the case may be, determined in accordance with Article 4 of the Supplemental Indenture. 

As provided in and subject to the provisions of the Indenture, the Company will make all payments in respect of the Fundamental Change

at the time of payment is legal tender for payment of public and private debts. 
 The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be effected under the Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified 

  
 A-4 








 
percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture
and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to
the Security, the Holders of not less than 25% in principal amount of the Securities at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the
Trustee indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding,
for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or interest hereon or amounts due
upon conversion on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of (including the Fundamental Change Purchase Price), interest on and the
