such lower amount as the Company may choose in its sole and absolute discretion) and the Holder of such Physical Note entitled to such payment has delivered to the Paying Agent or the Trustee, no later than the time set forth in the immediately
following sentence, a written request that the Company make such payment by wire transfer to an account of such Holder within the United States, by wire transfer of immediately available funds to such account; and (ii) in all other cases, by
check mailed to the address of the Holder of such Physical Note entitled to such payment as set forth in the Register. To be timely, such written request must be so delivered no later than the Close of Business on the following date: (x) with
respect to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular Record Date; (y) with respect to any cash Conversion Consideration, the relevant Conversion Date; and (z) with respect to any other
payment, the date that is fifteen (15) calendar days immediately before the date such payment is due.

 Section 2.05.    ACCRUAL OF
INTEREST; DEFAULTED AMOUNTS; WHEN PAYMENT DATE IS NOT A BUSINESS DAY. 

(A)    Accrual of Interest. Each Note will accrue interest at a rate per annum equal to 6.50% (the “Stated
Interest”), plus any Special Interest that may accrue pursuant to Section 7.03. Stated Interest on each Note will (i) accrue from, and including, the most recent date to which Stated Interest has been paid or duly
provided for (or, if no Stated Interest has theretofore been paid or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated Interest will begin to accrue in such circumstance)
to, but excluding, the date of payment of such Stated Interest; and (ii) be, subject to Sections 4.02(D), 4.03(E) and 5.02(D) (but without duplication of any payment of interest), payable semi-annually in arrears on
each Interest Payment Date, beginning on the first Interest Payment Date set forth in the certificate representing such Note, to the Holder of such Note as of the Close of Business on the immediately preceding Regular Record Date. Special Interest
will accrue from the dates and during the periods specified in Section 7.03 and at the rates specified in such section. Stated Interest, and, if applicable, Special Interest, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. 

(B)    Defaulted Amounts. If the Company fails to pay any amount (a “Defaulted Amount”) payable on
a Note on or before the due date therefor as provided in the Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise
entitled to such payment; (ii) to the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per annum at which Stated Interest accrues, from, and including, such
due date to, but excluding, the date of payment of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment date selected by the Company to the Holder of such Note as of the Close of
Business on a special record date selected by the Company, provided that such special record date must be no more than fifteen (15), nor less than ten (10), calendar days before such payment date; and (iv) at least fifteen
(15) calendar days before such special record date, the Company will send notice to the Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and Default Interest to be paid on
such payment date. 
 (C)    Delay of Payment when Payment Date is Not a Business Day. If the due date for a
payment on a Note as provided in the Indenture is not a Business Day, then, notwithstanding anything to the contrary in the Indenture or the Notes, such payment may be made on the immediately following Business Day and no interest will accrue on
such payment as a result of the related delay. Solely for purposes of the immediately preceding sentence, a day on which the applicable place of payment is authorized or required by law or executive order to close or be closed will be deemed not to
be a “Business Day.” 
 Section 2.06.    REGISTRAR, PAYING AGENT
AND CONVERSION AGENT. 
 (A)    Generally. The Company will
maintain (i) an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States where
Notes may be presented for payment (the “Paying Agent”); and (iii) an office or agency in the continental 

  
 - 17 - 













 
United States where Notes may be presented for conversion (the “Conversion Agent”). If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, then the
Trustee will act as such. For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent. 

(B)    Duties of the Registrar. The Registrar will keep a record (the “Register”) of the names and
addresses of the Holders, the Notes held by each Holder and the transfer, exchange, repurchase, Redemption and conversion of Notes. Absent manifest error, the entries in the Register will be conclusive and the Company and the Trustee may treat each
Person whose name is recorded as a Holder in the Register as a Holder for all purposes. The Register will be in written form or in any form capable of being converted into written form reasonably promptly. 

(C)    Co-Agents; Company’s Right to Appoint Successor Registrars, Paying
Agents and Conversion Agents. The Company may appoint one or more co-Registrars, co-Paying Agents and co-Conversion Agents,
each of whom will be deemed to be a Registrar, Paying Agent or Conversion Agent, as applicable, under the Indenture. Subject to Section 2.06(A), the Company may change any Registrar, Paying Agent or Conversion Agent
(including appointing itself or any of its Subsidiaries to act in such capacity) without notice to any Holder. The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to the
Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions of the Indenture that relate to such Note Agent. 

(D)    Initial Appointments. The Company appoints the Trustee as the initial Paying Agent, the initial Registrar
and the initial Conversion Agent. 
 Section 2.07.    PAYING AGENT AND
CONVERSION AGENT TO HOLD PROPERTY IN TRUST. 

The Company will require each Paying Agent or Conversion Agent that is not the Trustee to agree in writing that such Note Agent will
(A) hold in trust for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery due on the Notes; and (B) notify the Trustee of any default by the Company in making any such payment
or delivery. The Company, at any time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as applicable, all money and other property held by it to the Trustee, after which payment
or delivery, as applicable, such Note Agent (if not the Company or any of its Subsidiaries) will have no further liability for such money or property. If the Company or any of its Subsidiaries acts as Paying Agent or Conversion Agent, then
(A) it will segregate and hold in a separate trust fund for the benefit of the Holders or the Trustee all money and other property held by it as Paying Agent or Conversion Agent; and (B) references in the Indenture or the Notes to the
Paying Agent or Conversion Agent holding cash or other property, or to the delivery of cash or other property to the Paying Agent or Conversion Agent, in each case for payment or delivery to any Holders or the Trustee or with respect to the Notes,
will be deemed to refer to cash or other property so segregated and held separately, or to the segregation and separate holding of such cash or other property, respectively. Upon the occurrence of any event pursuant to clause
(ix) or (x) of Section 7.01(A) with respect to the Company (or with respect to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or
Conversion Agent, as applicable, for the Notes. 

  
 - 18 - 













 Section 2.08.    HOLDER LISTS. 

If the Trustee is not the Registrar, the Company will furnish to the Trustee, no later than seven (7) Business Days before each Interest
Payment Date, and at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may reasonably require, of the names and addresses of the Holders. 

Section 2.09.    LEGENDS. 

(A)    Global Note Legend. Each Global Note will bear the Global Note Legend (or any similar legend, not
inconsistent with the Indenture, required by the Depositary for such Global Note). 
 (B)    Other Legends. A
Note may bear any other legend or text, not inconsistent with the Indenture, as may be required by applicable law or by any securities exchange or automated quotation system on which such Note is traded or quoted. 

(C)    Acknowledgement and Agreement by the Holders. A Holder’s acceptance of any Note bearing any legend
required by this Section 2.09 will constitute such Holder’s acknowledgement of, and agreement to comply with, the restrictions set forth in such legend. 

Section 2.10.    TRANSFERS AND EXCHANGES; CERTAIN
TRANSFER RESTRICTIONS. 
 (A)    Provisions Applicable to All Transfers and
Exchanges. 
 (i)    Subject to this Section 2.10, Physical Notes and
beneficial interests in Global Notes may be transferred or exchanged from time to time and the Registrar will record each such transfer or exchange in the Register. 

(ii)    Each Note issued upon transfer or exchange of any other Note (such other Note being referred to as
the “old Note” for purposes of this Section 2.10(A)(ii)) or portion thereof in accordance with the Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the same
benefits under the Indenture, as such old Note or portion thereof, as applicable. 
 (iii)    The
Company, the Guarantors, the Trustee and the Note Agents will not impose any service charge on any Holder for any transfer, exchange or conversion of Notes, but the Company, the Guarantors, the Trustee, the Registrar and the Conversion Agent may
require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Notes, other than exchanges pursuant to Section 2.11,
2.16 or 8.05 not involving any transfer. 
 (iv)    Notwithstanding anything to the
contrary in the Indenture or the Notes, a Note may not be transferred or exchanged in part unless the portion to be so transferred or exchanged is in an Authorized Denomination. 

  
 - 19 - 













 (v)    The Trustee will have no obligation or duty to
monitor, determine or inquire as to compliance with any transfer restrictions imposed under the Indenture or applicable law with respect to any Note Security, other than to require the delivery of such certificates or other documentation or evidence
as expressly required by the Indenture and to examine the same to determine substantial compliance as to form with the requirements of the Indenture. 

(vi)    Each Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any,
required by Section 2.09. 
 (vii)    Upon satisfaction of the requirements of
the Indenture to effect a transfer or exchange of any Note, the Company will cause such transfer or exchange to be effected as soon as reasonably practicable but in no event later than the second (2nd) Business Day after the date of such
satisfaction. 
 (B)    Transfers and Exchanges of Global Notes. 

(i)    Subject to the immediately following sentence, no Global Note may be transferred or exchanged in
whole except (x) by the Depositary to a nominee of the Depositary; (y) by a nominee of the Depositary to the Depositary or to another nominee of the Depositary; or (z) by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary. No Global Note (or any portion thereof) may be transferred to, or exchanged for, a Physical Note; provided, however, that a Global Note will be exchanged, pursuant to customary procedures, for
one or more Physical Notes if: 
 (1)    (x) the Depositary notifies the Company or the Trustee that the
Depositary is unwilling or unable to continue as depositary for such Global Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and, in each case, the Company fails to
appoint a successor Depositary within ninety (90) days of such notice or cessation; 
 (2)    an
Event of Default has occurred and is continuing and the Company, the Trustee or the Registrar has received a written request from the Depositary, or from a holder of a beneficial interest in such Global Note, to exchange such Global Note or
beneficial interest, as applicable, for one or more Physical Notes; or 
 (3)    the Company, in its sole
discretion, permits the exchange of any beneficial interest in such Global Note for one or more Physical Notes at the request of the owner of such beneficial interest. 

(ii)    Upon satisfaction of the requirements of the Indenture to effect a transfer or exchange of any
Global Note (or any portion thereof): 
 (1)    the Trustee will reflect any resulting decrease of the
principal amount of such Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if such 

  
 - 20 - 













 
notation results in such Global Note having a principal amount of zero, the Company may (but is not required to) instruct the Trustee to cancel such Global Note pursuant to
Section 2.14); 
 (2)    if required to effect such transfer or exchange, then
the Trustee will reflect any resulting increase of the principal amount of any other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other Global Note; 

(3)    if required to effect such transfer or exchange, then the Company will issue, execute and deliver,
and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Global Note bearing each legend, if any, required by Section 2.09; and 

(4)    if such Global Note (or such portion thereof), or any beneficial interest therein, is to be
exchanged for one or more Physical Notes, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in
Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Global Note to be so exchanged; (y) are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant to
customary procedures); and (z) bear each legend, if any, required by Section 2.09. 

(iii)    Each transfer or exchange of a beneficial interest in any Global Note will be made in accordance
with the Depositary Procedures. 
 (C)    Transfers and Exchanges of Physical Notes. 

(i)    Subject to this Section 2.10, a Holder of a Physical Note may
(x) transfer such Physical Note (or any portion thereof in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in an Authorized Denomination) for one or more other Physical Notes
in Authorized Denominations having an aggregate principal amount equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted by the Depositary Procedures, transfer such
Physical Note (or any portion thereof in an Authorized Denomination) in exchange for a beneficial interest in one or more Global Notes; provided, however, that, to effect any such transfer or exchange, such Holder must surrender such
Physical Note to be transferred or exchanged to the office of the Registrar, together with any endorsements or transfer instruments reasonably required by the Company, the Trustee or the Registrar. 

(ii)    Upon the satisfaction of the requirements of the Indenture to effect a transfer or exchange of any
Physical Note (such Physical Note being referred to as the “old Physical Note” for purposes of this Section 2.10(C)(ii)) of a Holder (or any portion of such old Physical Note in an Authorized Denomination): 

(1)    such old Physical Note will be promptly cancelled pursuant to
Section 2.14; 

  
 - 21 - 













 (2)    if such old Physical Note is to be so transferred
or exchanged only in part, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized
Denominations and have an aggregate principal amount equal to the principal amount of such old Physical Note not to be so transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required
by Section 2.09; 
 (3)    in the case of a transfer: 

(a)    to the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or
such portion thereof) to be so transferred in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global Notes by notation on the “Schedule of Exchanges of Interests in the
Global Note” forming part of such Global Note(s), which increase(s) are in Authorized Denominations and aggregate to the principal amount to be so transferred, and which Global Note(s) bear each legend, if any, required by
Section 2.09; provided, however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no Global Notes bearing each legend, if any, required by
Section 2.09 then exist, because any such increase will result in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary or otherwise), then the
Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate
principal amount equal to the principal amount to be so transferred; and (y) bear each legend, if any, required by Section 2.09; and 

(b)    to a transferee that will hold its interest in such old Physical Note (or such portion thereof) to
be so transferred in the form of one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that
(x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; (y) are registered in the name of such transferee; and (z) bear each legend, if any, required by
Section 2.09; and 
 (4)    in the case of an exchange, the Company will issue,
execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to
the principal amount to be so exchanged; (y) are registered in the name of the Person to whom such old Physical Note was registered; and (z) bear each legend, if any, required by Section 2.09.

 (D)    Transfers of Notes Subject to Redemption, Repurchase or
Conversion. Notwithstanding anything to the contrary in the Indenture or the Notes, the Company, the Guarantors, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has been
surrendered for conversion, except to the extent that any portion of such Note is not subject to conversion; (ii) is subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to
Section 4.02(F), except to the extent that any portion of such Note is not subject to such notice or the Company fails to pay the applicable Fundamental Change Repurchase Price when due; or (iii) has been selected for
Redemption pursuant to a Redemption Notice, except to the extent that any portion of such Note is not subject to Redemption or the Company fails to pay the applicable Redemption Price when due. 

Section 2.11.    EXCHANGE AND CANCELLATION OF NOTES
TO BE CONVERTED OR TO BE REPURCHASED PURSUANT TO A REPURCHASE UPON
FUNDAMENTAL CHANGE OR REDEMPTION. 
 (A)    Partial
Conversions of Physical Notes and Partial Repurchases of Physical Notes Pursuant to a Repurchase Upon Fundamental Change or Redemption. If only a portion of a Physical Note of a Holder is to be converted pursuant to Article 5 or
repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, as soon as reasonably practicable after such Physical Note is surrendered for such conversion or repurchase, as applicable, the Company will cause such Physical Note
to be exchanged, pursuant and subject to Section 2.10(C), for (i) one or more Physical Notes that are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical
Note that is not to be so converted or repurchased, as applicable, and deliver such Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal to the principal amount to be so converted or repurchased, as
applicable, which Physical Note will be converted or repurchased, as applicable, pursuant to the terms of this Indenture; provided, however, that the Physical Note referred to in this clause (ii) need not be issued at any
time after which such principal amount subject to such conversion or repurchase, as applicable, is deemed to cease to be outstanding pursuant to Section 2.17. 

(B)    Cancellation of Notes that Are Converted and Notes that Are Repurchased Pursuant to a Repurchase Upon
Fundamental Change or Redemption. 
 (i)    Physical Notes. If a Physical Note (or any portion
thereof that has not theretofore been exchanged pursuant to Section 2.11(A)) of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then,
promptly after the later of the time such Physical Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.17 and the time such Physical Note is surrendered for such conversion or repurchase, as
applicable, (1) such Physical Note will be cancelled pursuant to Section 2.14; and (2) in the case of a partial conversion or repurchase, as applicable, the Company will issue, execute and deliver to such Holder,
and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and 

  
 - 23 - 













 
have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased, as applicable; (y) are registered in the name of such
Holder; and (z) bear each legend, if any, required by Section 2.09. 

(ii)    Global Notes. If a Global Note (or any portion thereof) is to be converted pursuant to
Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, promptly after the time such Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.17, the
Trustee will reflect a decrease of the principal amount of such Global Note in an amount equal to the principal amount of such Global Note to be so converted or repurchased, as applicable, by notation on the “Schedule of Exchanges of Interests
in the Global Note” forming part of such Global Note (and, if the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to Section 2.14). 

Section 2.12.    REPLACEMENT NOTES. 

If a Holder of any Note claims that such Note has been mutilated, lost, destroyed or wrongfully taken, then the Company will issue, execute and
deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a replacement Note upon surrender to the Trustee of such mutilated Note, or upon delivery to the Trustee of evidence of such loss,
destruction or wrongful taking reasonably satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Note, the Company and the Trustee may require the Holder thereof to provide such security or indemnity that
is reasonably satisfactory to the Company and the Trustee to protect the Company and the Trustee from any loss that any of them may suffer if such Note is replaced. 

Every replacement Note issued pursuant to this Section 2.12 will be an additional obligation of the Company and will
be entitled to all of the benefits of the Indenture equally and ratably with all other Notes issued under the Indenture. 

Section 2.13.    REGISTERED HOLDERS; CERTAIN RIGHTS
WITH RESPECT TO GLOBAL NOTES. 
 Only the Holder of a Note
will have rights under the Indenture as the owner of such Note. Without limiting the generality of the foregoing, Depositary Participants will have no rights as such under the Indenture with respect to any Global Note held on their behalf by the
Depositary or its nominee, or by the Trustee as its custodian, and the Company, the Guarantors, the Trustee and the Note Agents, and their respective agents, may treat the Depositary as the absolute owner of such Global Note for all purposes
whatsoever; provided, however, that (A) the Holder of any Global Note may grant proxies and otherwise authorize any Person, including Depositary Participants and Persons that hold interests in Notes through Depositary
Participants, to take any action that such Holder is entitled to take with respect to such Global Note under the Indenture or the Notes; and (B) the Company and the Trustee, and their respective agents, may give effect to any written
certification, proxy or other authorization furnished by the Depositary. 

  
 - 24 - 













 Section 2.14.    CANCELLATION. 

The Company may at any time deliver Notes to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent will
forward to the Trustee each Note duly surrendered to them for transfer, exchange, payment or conversion. The Trustee will promptly cancel all Notes so surrendered to it in accordance with its customary procedures. Without limiting the generality of
Section 2.03(B), the Company may not originally issue new Notes to replace Notes that it has paid or that have been cancelled upon transfer, exchange, payment or conversion. 

Section 2.15.    NOTES HELD BY THE COMPANY
OR ITS AFFILIATES. 
 Without limiting the generality of Section 2.17, in
determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates will be deemed not to be outstanding; provided,
however, that, for purposes of determining whether the Trustee is protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded. 

Section 2.16.    TEMPORARY NOTES. 

Until definitive Notes are ready for delivery, the Company may issue, execute and deliver, and, upon receipt of a Company Order, the Trustee
will authenticate, in each case in accordance with Section 2.02, temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for
temporary Notes. The Company will promptly prepare, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, definitive Notes in exchange for temporary Notes. Until so
exchanged, each temporary Note will in all respects be entitled to the same benefits under the Indenture as definitive Notes. 

Section 2.17.    OUTSTANDING NOTES. 

(A)    Generally. The Notes that are outstanding at any time will be deemed to be those Notes that, at such time,
have been duly executed and authenticated, excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to the Trustee for cancellation in accordance with
Section 2.14; (ii) assigned a principal amount of zero by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such Note; (iii) paid in full
(including upon conversion) in accordance with the Indenture; or (iv) deemed to cease to be outstanding to the extent provided in, and subject to, clause (B), (C) or (D) of this Section 2.17.

 (B)    Replaced Notes. If a Note is replaced pursuant to Section 2.12, then such
Note will cease to be outstanding at the time of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held by a “bona fide purchaser” under applicable law. 

(C)    Maturing Notes and Notes Called for Redemption or Subject to Repurchase. If, on a Redemption Date, a
Fundamental Change Repurchase Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Redemption Price, Fundamental Change Repurchase Price or principal amount, respectively, together, in each case, with the aggregate


  
 - 25 - 













 
interest, in each case due on such date, then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions thereof) to be redeemed or repurchased, or that
mature, on such date will be deemed, as of such date, to cease to be outstanding, except to the extent provided in Sections 4.02(D), 4.03(E) or 5.02(D); and (ii) the rights of the Holders of such Notes (or such portions
thereof), as such, will terminate with respect to such Notes (or such portions thereof), other than the right to receive the Redemption Price, Fundamental Change Repurchase Price or principal amount, as applicable, of, and accrued and unpaid
interest on, such Notes (or such portions thereof), in each case as provided in the Indenture. 
 (D)    Notes to Be
Converted. At the Close of Business on the Conversion Date for any Note (or any portion thereof) to be converted, such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due,
pursuant to Section 5.03(B) or Section 5.02(D), upon such conversion) be deemed to cease to be outstanding, except to the extent provided in Section 5.02(D) or
Section 5.08. 
 (E)    Cessation of Accrual of Interest. Except as provided in
Sections 4.02(D), 4.03(E) or 5.02(D), interest will cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this Section 2.17, to cease to be outstanding, unless
there occurs a default in the payment or delivery of any cash or other property due on such Note. 

Section 2.18.    REPURCHASES BY THE COMPANY. 

The Company may, from time to time, repurchase Notes in open market purchases or in negotiated transactions without delivering prior notice to
Holders. 
 Section 2.19.    CUSIP AND ISIN NUMBERS. 

The Company may use one or more CUSIP or ISIN numbers to identify any of the Notes, and, if so, the Company and the Trustee will use such CUSIP
or ISIN number(s) in notices to Holders; provided, however, that (i) the Trustee makes no representation as to the correctness or accuracy of any such CUSIP or ISIN number; and (ii) the effectiveness of any such notice will
not be affected by any defect in, or omission of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN number(s) identifying any Notes. 

Article 3.     COVENANTS 

Section 3.01.    PAYMENT ON NOTES.

Repurchase Date or Interest Payment Date, and on the Maturity Date or any other date on which any cash amount is due on the Notes, the Company will deposit, or will cause there to be deposited, with the Paying Agent cash, in funds immediately
available on such date, sufficient to pay the cash amount due on the applicable Notes on such date. The Paying Agent will return to the Company, as soon as practicable, any money not required for such purpose.

 (A)    Generally. The Company will send to the Trustee copies of all reports that
the Company is required to file with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act within fifteen (15) calendar days after the date that the Company is required to file the same (after giving effect to all applicable grace
periods under the Exchange Act); provided, however, that the Company need not send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by the SEC.
Any report that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be sent to the Trustee at the time such report is so filed via the EDGAR system (or such successor). Upon the written request of any
Holder, the Trustee will provide to such Holder a copy of any report that the Company has sent the Trustee pursuant to this Section 3.02(A), other than a report that is deemed to be sent to the Trustee pursuant to the
preceding sentence. The Company will also comply with all of its obligations under Section 314(a)(1) of the Trust Indenture Act. 

(B)    Trustee’s Disclaimer. The Trustee need not determine whether the Company has filed any material via the
EDGAR system (or such successor). The sending or filing of reports pursuant to Section 3.02(A) is for informational purposes only and the Trustee’s receipt of such reports will not be deemed to actual or constitute
constructive notice to the Trustee of any information contained, or determinable from information contained, therein, including the Company’s compliance with any of its covenants under the Indenture (as to which the Trustee is entitled to
conclusively rely on Officer’s Certificates). 
 Section 3.03.    COMPLIANCE AND
DEFAULT CERTIFICATES. 
 (A)    Annual Compliance Certificate. Within ninety
(90) days after December 31, 2020 and each fiscal year of the Company ending thereafter, the Company will deliver an Officer’s Certificate to the Trustee stating (i) that the signatory thereto has supervised a review of the
activities of the Company and its Subsidiaries during such fiscal year with a view towards determining whether any Default or Event of Default has occurred; and (ii) whether, to such signatory’s knowledge, a Default or Event of Default has
occurred or is continuing (and, if so, describing all such Defaults or Events of Default and what action the Company is taking or proposes to take with respect thereto). 

(B)    Default Certificate. If a Default or Event of Default occurs, then the Company will, within thirty
(30) days after its first occurrence, deliver an Officer’s Certificate to the Trustee describing the same and what action the Company is taking or proposes to take with respect thereto. 

Section 3.04.    STAY, EXTENSION AND USURY LAWS.

 To the extent that it may lawfully do so, the Company (A) agrees that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, 

  
 - 27 - 













 
any stay, extension or usury law (wherever or whenever enacted or in force) that may affect the covenants or the performance of the Indenture; and (B) expressly waives all benefits or
advantages of any such law and agrees that it will not, by resort to any such law, hinder, delay or impede the execution of any power granted to the Trustee by the Indenture, but will suffer and permit the execution of every such power as though no
such law has been enacted. 
 Section 3.05.    ACQUISITION OF NOTES
BY THE COMPANY AND ITS AFFILIATES. 
 Without
limiting the generality of Section 2.17, Notes that the Company or any of its Subsidiaries have purchased or otherwise acquired will be deemed to remain outstanding (except to the extent provided in
Section 2.15) until such time as such Notes are delivered to the Trustee for cancellation. 

Section 3.06.    FURTHER INSTRUMENTS AND ACTS. 

At the Trustee’s request, the Company will execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to more effectively carry out the purposes of this Supplemental Indenture. 

Section 3.07.    EXISTENCE. 

Subject to Article 6, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate
existence. 
 Section 3.08.    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 Article VII of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder. 

Article 4.     REPURCHASE AND REDEMPTION 

Section 4.01.    NO SINKING FUND. 

No sinking fund is required to be provided for the Notes. 

Section 4.02.    RIGHT OF HOLDERS TO REQUIRE
THE COMPANY TO REPURCHASE NOTES UPON A FUNDAMENTAL CHANGE. 

(A)    Right of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change. Subject to the other
terms of this Section 4.02, if a Fundamental Change occurs, then each Holder will have the right (the “Fundamental Change Repurchase Right”) to require the Company to repurchase such Holder’s Notes (or
any portion thereof in an Authorized Denomination) on the Fundamental Change Repurchase Date for such Fundamental Change for a cash purchase price equal to the Fundamental Change Repurchase Price. 

  
 - 28 - 













 (B)    Repurchase Prohibited in Certain Circumstances. If the
principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (including a rescission as a result of the payment of the
related Fundamental Change Repurchase Price, and any related interest pursuant to the proviso to Section 4.02(D), on such Fundamental Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant
to this Section 4.02; and (ii) the Company will cause any Notes theretofore surrendered for such Repurchase Upon Fundamental Change to be returned to the Holders thereof (or, if applicable with respect to Global Notes,
cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary Procedures). 

(C)    Fundamental Change Repurchase Date. The Fundamental Change Repurchase Date for any Fundamental Change will
be a Business Day of the Company’s choosing that is no more than thirty five (35), nor less than twenty (20), Business Days after the date the Company sends the related Fundamental Change Notice pursuant to
Section 4.02(E). 
 (D)    Fundamental Change Repurchase Price. The Fundamental Change
Repurchase Price for any Note to be repurchased upon a Repurchase Upon Fundamental Change following a Fundamental Change is an amount in cash equal to the principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding,
the Fundamental Change Repurchase Date for such Fundamental Change; provided, however, that if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, then (i) the
Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Repurchase Upon Fundamental Change, to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid
interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Fundamental Change Repurchase Date is
before such Interest Payment Date); and (ii) the Fundamental Change Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Fundamental Change Repurchase Date. For the avoidance of doubt, if an
Interest Payment Date is not a Business Day within the meaning of Section 2.05(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued
and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day to Holders as of the Close of Business on the immediately preceding
Regular Record Date; and (y) the Fundamental Change Repurchase Price will include interest on Notes to be repurchased from, and including, such Interest Payment Date. 

(E)    Fundamental Change Notice. On or before the twentieth (20th) calendar day after the effective date of a
Fundamental Change, the Company will send to each Holder, the Trustee, the Conversion Agent (if other than the Trustee) and the Paying Agent a notice of such Fundamental Change (a “Fundamental Change Notice”). 

Such Fundamental Change Notice must state: 

(i)    briefly, the events causing such Fundamental Change; 

  
 - 29 - 













 (ii)    the effective date of such Fundamental Change;

 (iii)    the procedures that a Holder must follow to require the Company to repurchase its Notes
pursuant to this Section 4.02, including the deadline for exercising the Fundamental Change Repurchase Right and the procedures for submitting and withdrawing a Fundamental Change Repurchase Notice; 

(iv)    the Fundamental Change Repurchase Date for such Fundamental Change; 

(v)    the Fundamental Change Repurchase Price per $1,000 principal amount of Notes for such Fundamental
Change (and, if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to
Section 4.02(D)); 
 (vi)    the name and address of the Paying Agent and the
Conversion Agent; 
 (vii)    the Conversion Rate in effect on the date of such Fundamental Change Notice
and a description and quantification of any adjustments to the Conversion Rate that may result from such Fundamental Change (including pursuant to Section 5.07); 

(viii)    that Notes for which a Fundamental Change Repurchase Notice has been duly tendered and not duly
withdrawn must be delivered to the Paying Agent for the Holder thereof to be entitled to receive the Fundamental Change Repurchase Price; 

(ix)    that Notes (or any portion thereof) that are subject to a Fundamental Change Repurchase Notice that
has been duly tendered may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with the Indenture; and 

(x)    the CUSIP and ISIN numbers, if any, of the Notes. 

Neither the failure to deliver a Fundamental Change Notice nor any defect in a Fundamental Change Notice will limit the Fundamental Change
Repurchase Right of any Holder or otherwise affect the validity of any proceedings relating to any Repurchase Upon Fundamental Change. 

(F)    Procedures to Exercise the Fundamental Change Repurchase Right. 

(i)    Delivery of Fundamental Change Repurchase Notice and Notes to Be Repurchased. To exercise its
Fundamental Change Repurchase Right for a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent: 

(1)    before the Close of Business on the Business Day immediately before the related Fundamental Change
Repurchase Date (or such later time as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and 

  
 - 30 - 













 (2)    such Note, duly endorsed for transfer (if such
Note is a Physical Note) or by book-entry transfer (if such Note is a Global Note). 
 The Paying Agent will promptly deliver to the Company
a copy of each Fundamental Change Repurchase Notice that it receives. 
 (ii)    Contents of
Fundamental Change Repurchase Notices. Each Fundamental Change Repurchase Notice with respect to a Note must state: 

(1)    if such Note is a Physical Note, the certificate number of such Note; 

(2)    the principal amount of such Note to be repurchased, which must be an Authorized Denomination; and

 (3)    that such Holder is exercising its Fundamental Change Repurchase Right with respect to such
principal amount of such Note; 
 provided, however, that if such Note is a Global Note, then such Fundamental Change
Repurchase Notice must comply with the Depositary Procedures (and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this
Section 4.02(F)). 
 (iii)    Withdrawal of Fundamental Change Repurchase
Notice. A Holder that has delivered a Fundamental Change Repurchase Notice with respect to a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any time before the
Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date. Such withdrawal notice must state: 

(1)    if such Note is a Physical Note, the certificate number of such Note; 

(2)    the principal amount of such Note to be withdrawn, which must be an Authorized Denomination; and

 (3)    the principal amount of such Note, if any, that remains subject to such Fundamental Change
Repurchase Notice, which must be an Authorized Denomination; 
 provided, however, that if such Note is a Global Note, then
such withdrawal notice must comply with the Depositary Procedures (and any such withdrawal notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)).

 Upon receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly
deliver a copy of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note 

  
 - 31 - 













 
(or such portion thereof in accordance with Section 2.11, treating such Note as having been then surrendered for partial repurchase in the amount set forth in such
withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to any Global Note, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the
applicable beneficial interest in such Note in accordance with the Depositary Procedures). 
 (G)    Payment of the
Fundamental Change Repurchase Price. Without limiting the Company’s obligation to deposit the Fundamental Change Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the
Fundamental Change Repurchase Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon Fundamental Change to be paid to the Holder thereof on or before the later of (i) the applicable Fundamental Change Repurchase
Date; and (ii) the date (x) such Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the repurchase, and the delivery to the Paying Agent, of such Holder’s
beneficial interest in such Note to be repurchased are complied with (in the case of a Global Note). For the avoidance of doubt, interest payable pursuant to the proviso to Section 4.02(D) on any Note to be repurchased
pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is delivered or such Depositary Procedures are complied with pursuant to the first sentence of this
Section 4.02(G). 
 (H)    Third Party May Conduct Repurchase Offer In Lieu of the
Company. Notwithstanding anything to the contrary in this Section 4.02, the Company will be deemed to satisfy its obligations under this Section 4.02 if (i) one or more third parties
conduct any Repurchase Upon Fundamental Change and related offer to repurchase Notes otherwise required by this Section 4.02 in a manner that would have satisfied the requirements of this
Section 4.02 if conducted directly by the Company and (ii) an owner of a beneficial interest in any Note repurchased by such third party or parties will not receive a lesser amount (as a result of taxes, additional
expenses or for any other reason) than such owner would have received had the Company repurchased such Note. 

(I)    No Requirement to Conduct an Offer to Repurchase Notes if the Fundamental Change Results in the Notes Becoming
Convertible into an Amount of Cash Exceeding the Fundamental Change Repurchase Price. Notwithstanding anything to the contrary in this Section 4.02, the Company will not be required to send a Fundamental Change Notice
pursuant to Section 4.02(E), or offer to repurchase or repurchase any Notes pursuant to this Section 4.02, in connection with a Fundamental Change occurring pursuant to clause (B)(ii) (or
pursuant to clause (A) that also constitutes a Fundamental Change occurring pursuant to clause (B)(ii)) of the definition thereof, if (i) such Fundamental Change constitutes a Common Stock Change Event whose Reference
Property consists, entirely or in part, of cash in U.S. dollars; (ii) immediately after such Fundamental Change, the Notes become convertible, pursuant to Section 5.09(A) and, if applicable,
Section 5.07, into consideration that includes such cash in an amount per $1,000 aggregate principal amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per $1,000 aggregate principal amount of
Notes (calculated assuming that the same includes accrued and unpaid interest to, but excluding, the latest possible Fundamental Change Repurchase Date for such Fundamental Change); and (iii) the Company timely sends the notice relating to such
Fundamental Change required pursuant to Section 5.01(C)(i)(3)(b) and includes, in such notice, a statement that the Company is relying on this Section 4.02(I). 

  
 - 32 - 













 (J)    Compliance with Applicable Securities Laws. To the extent
applicable, the Company will comply, in all material respects, with all federal and state securities laws in connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and 14e-1 under the Exchange Act and filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change in the manner set forth in the Indenture;
provided, however, that, to the extent that the Company’s obligations pursuant to this Section 4.02 conflict with any law or regulation that is applicable to the Company and enacted after the Issue Date,
the Company’s compliance with such law or regulation will not be considered to be a Default of such obligations. 

(K)    Repurchase in Part. Subject to the terms of this Section 4.02, Notes may be
repurchased pursuant to a Repurchase Upon Fundamental Change in part, but only in Authorized Denominations. Provisions of this Section 4.02 applying to the repurchase of a Note in whole will equally apply to the repurchase
of a permitted portion of a Note. 
 (L)    The Paying Agent. For purposes of this
Section 4.02, the Paying Agent may be any agent, depositary, tender agent, paying agent or other agent appointed by the Company to accomplish the purposes set forth herein. 

Section 4.03.    RIGHT OF THE COMPANY TO
REDEEM THE NOTES. 
 (A)    No Right to Redeem Before
July 5, 2023. The Company may not redeem the Notes at its option at any time before July 5, 2023. 

(B)    Right to Redeem the Notes on or after July 5, 2023. Subject to the terms of this
Section 4.03, the Company has the right, at its election, to redeem all, or any portion in an Authorized Denomination, of the Notes, at any time, and from time to time, on a Redemption Date on or after July 5, 2023 and
on or before the twentieth (20th) Scheduled Trading Day immediately before the Maturity Date, for a cash purchase price equal to the Redemption Price, but only if the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty
percent (130%) of the Conversion Price on (i) each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the Trading Day immediately before the
Redemption Notice Date for such Redemption; and (ii) the Trading Day immediately before such Redemption Notice Date. For the avoidance of doubt, the calling of any Notes for Redemption will constitute a Make-Whole Fundamental Change with
respect to such Notes pursuant to clause (B) of the definition thereof. 
 (C)    Redemption Prohibited
in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or before the Redemption Date (including a rescission as a result of the payment of the related Redemption Price,
and any related interest pursuant to the proviso to Section 4.03(E), on such Redemption Date), then (i) the Company may not call for Redemption or otherwise redeem any Notes pursuant to this
Section 4.03; and (ii) the Company will cause any Notes theretofore surrendered for such Redemption to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for
book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interests in such Notes in accordance with the Depositary Procedures). 

  
 - 33 - 













 (D)    Redemption Date. The Redemption Date for any Redemption
will be a Business Day of the Company’s choosing that is no more than forty five (45), nor less than twenty five (25), Scheduled Trading Days after the Redemption Notice Date for such Redemption; provided, however, that if,
in accordance with Section 5.03(A)(i)(3), the Company has elected to settle all conversions of Notes with a Conversion Date that occurs on or after such Redemption Notice Date and on or before the Business Day immediately
before the Redemption Date by Physical Settlement, then the Company may instead elect to choose a Redemption Date that is a Business Day no more than sixty (60), nor less than thirty (30), calendar days after such Redemption Notice Date. 

(E)    Redemption Price. The Redemption Price for any Note called for Redemption is an amount in cash equal to the
principal amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption; provided, however, that if such Redemption Date is after a Regular Record Date and on or before the
next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Redemption, to receive, on or, at the Company’s election, before such Interest Payment
Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Redemption Date is
before such Interest Payment Date); and (ii) the Redemption Price will not include accrued and unpaid interest on such Note to, but excluding, such Redemption Date. For the avoidance of doubt, if an Interest Payment Date is not a Business Day
within the meaning of Section 2.05(C) and such Redemption Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest
Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day to Holders as of the Close of Business on the immediately preceding Regular Record Date; and (y) the Redemption Price will include
interest on Notes to be redeemed from, and including, such Interest Payment Date. 
 (F)    Redemption Notice. To
call any Notes for Redemption, the Company must send to each Holder of such Notes, the Trustee and the Paying Agent a written notice of such Redemption (a “Redemption Notice”) containing the information set forth in the Redemption
Notice. 
 Such Redemption Notice must state: 

(i)    that such Notes have been called for Redemption, briefly describing the Company’s Redemption
right under the Indenture; 
 (ii)    the Redemption Date for such Redemption; 

(iii)    the Redemption Price per $1,000 principal amount of Notes for such Redemption (and, if the
Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso to Section 4.03(E)); 

  
 - 34 - 













 (iv)    the name and address of the Paying Agent and the
Conversion Agent; 
 (v)    that Notes called for Redemption may be converted at any time before the
Close of Business on the Business Day immediately before the Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price in full);

 (vi)    the Conversion Rate in effect on the Redemption Notice Date for such Redemption and a
description and quantification of any adjustments to the Conversion Rate that may result from such Redemption (including pursuant to Section 5.07); 

(vii)    the Settlement Method that will apply to all conversions of Notes with a Conversion Date that
occurs on or after such Redemption Notice Date and on or before the Business Day before such Redemption Date; and 

(viii)    the CUSIP and ISIN numbers, if any, of the Notes. 

On or before the Redemption Notice Date, the Company will send a copy of such Redemption Notice to the Trustee and the Paying Agent. 

(G)    Selection and Conversion of Notes to Be Redeemed in Part. If less than all Notes then outstanding are called
for Redemption, then: 
 (i)    the Notes to be redeemed will be selected by the Company as follows:
(1) in the case of Global Notes, in accordance with the Depositary Procedures; and (2) in the case of Physical Notes, pro rata, by lot or by such other method the Company considers fair and appropriate; and 

(ii)    if only a portion of a Note is subject to Redemption and such Note is converted in part, then the
converted portion of such Note will be deemed to be from the portion of such Note that was subject to Redemption. 

(H)    Payment of the Redemption Price. Without limiting the Company’s obligation to deposit the Redemption
Price by the time proscribed by Section 3.01(B), the Company will cause the Redemption Price for a Note (or portion thereof) subject to Redemption to be paid to the Holder thereof on or before the applicable Redemption
Date. For the avoidance of doubt, interest payable pursuant to the proviso to Section 4.03(E) on any Note (or portion thereof) subject to Redemption must be paid pursuant to such proviso. 

(I)    Special Provisions for Partial Calls. If the Company elects to redeem less than all of the outstanding Notes
pursuant to this Section 4.03, and the Holder of any Note, or any owner of a beneficial interest in any Global Note, is reasonably not able to determine, before the Close of Business on the twenty second (22nd) Scheduled
Trading Day (or, if, in accordance with Section 5.03(A)(i)(3), the Company has elected to settle all conversions of Notes with a Conversion Date that occurs on or after the Redemption Notice Date for such Redemption and on
or before the Business Day immediately before the Redemption Date by Physical Settlement, 

  
 - 35 - 













 
the tenth (10th) calendar day) immediately before the Redemption Date for such Redemption, whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such Redemption,
then such Holder or owner, as applicable, will be entitled to convert such Note or beneficial interest, as applicable, at any time before the Close of Business on the Business Day immediately before such Redemption Date, and each such conversion
will be deemed to be of a Note called for Redemption for purposes of this Section 4.03 and Sections 5.01(C)(i)(4) and 5.07; 

Article 5.     CONVERSION 

Section 5.01.    RIGHT TO CONVERT. 

(A)    Generally. Subject to the provisions of this Article 5, each Holder may, at its option, convert such
Holder’s Notes into Conversion Consideration. 
 (B)    Conversions in Part. Subject to the terms of the
Indenture, Notes may be converted in part, but only in Authorized Denominations. Provisions of this Article 5 applying to the conversion of a Note in whole will equally apply to conversions of a permitted portion of a Note. 

(C)    When Notes May Be Converted. 

(i)    Generally. Subject to Section 5.01(C)(ii), a Note may be converted
only in the following circumstances: 
 (1)    Conversion upon Satisfaction of Common Stock Sale Price
Condition. A Holder may convert its Notes during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on September 30, 2020 if the Last Reported Sale Price per share of Common Stock
exceeds one hundred and thirty percent (130%) of the Conversion Price for each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the last Trading Day
of the immediately preceding calendar quarter. 
 (2)    Conversion upon Satisfaction of Note Trading
Price Condition. A Holder may convert its Notes during the five (5) consecutive Business Days immediately after any ten (10) consecutive Trading Day period (such ten (10) consecutive Trading Day period, the “Measurement
Period”) if the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was less than ninety eight
percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence is referred to in the Indenture as the
“Trading Price Condition.” 
 The Trading Price will be determined by the Bid Solicitation Agent pursuant to this
Section 5.01(C)(i)(2) and the definition of “Trading Price.” The Bid 

  
 - 36 - 













 
Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination in writing and provided the names
and contact information of the nationally recognized securities dealers selected by the Company, and the Company will have no obligation to make such request (or seek bids itself) unless a Holder provides the Company with reasonable evidence that
the Trading Price per $1,000 principal amount of Notes would be less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock and the Conversion Rate. If a Holder provides such evidence, then the
Company will (if acting as Bid Solicitation Agent), or will instruct the Bid Solicitation Agent to, determine the Trading Price of the Notes, in accordance with the bids solicited by the Bid Solicitation Agent, beginning on the next Trading Day and
on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the
Conversion Rate on such Trading Day. If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the same. If, on any Trading Day after
the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on
such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the same. 

(3)    Conversion upon Specified Corporate Events. 

(a)    Certain Distributions. If the Company elects to: 

(I)    distribute, to all or substantially all holders of Common Stock, any rights, options or warrants
(other than rights issued pursuant to a stockholder rights plan) entitling them, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price
per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced
(determined in the manner set forth in the third paragraph of Section 5.05(A)(ii)); or 

(II)    distribute, to all or substantially all holders of Common Stock, assets or securities of the
Company or rights to purchase the Company’s securities, which distribution per share of Common Stock has a value, as reasonably determined by the Board of Directors, exceeding fifteen percent (15%) of the Last Reported Sale Price per share of
Common Stock on the Trading Day immediately before the date such distribution is announced, 

  
 - 37 - 













 then, in either case, (x) the Company will send notice of such distribution, and of
the related right to convert Notes, to Holders, the Trustee and the Conversion Agent at least twenty five (25) Scheduled Trading Days before the Ex-Dividend Date for such distribution; and (y) once
the Company has sent such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend Date and the Company’s
announcement that such distribution will not take place; provided, however, that the Notes will not become convertible pursuant to clause (y) above (but the Company will be required to send notice of such distribution pursuant to
clause (x) above) on account of such distribution if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder, in such distribution without having to convert such
Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the record date for such distribution; and (ii) the aggregate principal amount (expressed in
thousands) of Notes held by such Holder on such record date; provided, further, that if the Company is then otherwise permitted to settle conversions of Notes by Physical Settlement (and, for the avoidance of doubt, the Company has not
elected another Settlement Method to apply, including pursuant to Section 5.03(A)(i)(1)), then the Company may instead elect to provide such notice at least ten (10) Scheduled Trading Days before such Ex-Dividend Date, in which case (x) the Company must settle all conversions of Notes with a Conversion Date occurring on or after the date the Company provides such notice and on or before the Business Day
immediately before the Ex-Dividend Date for such distribution (or any earlier announcement by the Company that such distribution will not take place) by Physical Settlement; and (y) such notice must state
that all such conversions will be settled by Physical Settlement. 
 (b)    Certain Corporate
Events. If a Fundamental Change, Make-Whole Fundamental Change (other than a Make-Whole Fundamental Change pursuant to clause (B) of the definition thereof) or Common Stock Change Event occurs (other than (i) a merger or other
business combination transaction that is effected solely to change the Company’s jurisdiction of incorporation or (ii) an internal reorganization among the Company and one or more of its wholly owned Subsidiaries or a parent entities of
the Company (in each case, direct or indirect) such that, following such reorganization, such Subsidiaries or parent entities directly or indirectly own 100% of the Company’s outstanding equity and, in the case of each of clauses (i) and
(ii) of this Section 1.01(A)(i)(1)(b), that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and (y) results in a reclassification, conversion or exchange of outstanding Common Stock
solely into shares of Common 

  
 - 38 - 













 
Stock of the surviving entity and such common stock becomes Reference Property, then, in each case, Holders may convert their Notes at any time from, and including, the effective date of such
transaction or event to, and including, the thirty fifth (35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change (other than an Exempted Fundamental Change), to, but excluding, the related
Fundamental Change Repurchase Date); provided, however, that if the Company does not provide the notice referred to in the immediately following sentence by such effective date, then the last day on which the Notes are convertible
pursuant to this sentence will be extended by the number of Business Days from, and including, such effective date to, but excluding, the date the Company provides such notice. No later than such effective date, the Company will send notice to the
Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such transaction or event, such effective date and the related right to convert Notes. 

(4)    Conversion upon Redemption. If the Company calls any Note for Redemption, then the Holder of
such Note may convert such Note at any time before the Close of Business on the Business Day immediately before the related Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until
such time as the Company pays such Redemption Price in full). 
 (5)    Conversions During Free
Convertibility Period. A Holder may convert its Notes at any time from, and including, April 1, 2025 until the Close of Business on the Scheduled Trading Day immediately before the Maturity Date. 

For the avoidance of doubt, the Notes may become convertible pursuant to any one or more of the preceding
sub-paragraphs of this Section 5.01(C)(i) and the Notes ceasing to be convertible pursuant to a particular sub-paragraph of this
Section 5.01(C)(i) will not preclude the Notes from being convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i). 

(ii)    Limitations and Closed Periods. Notwithstanding anything to the contrary in the Indenture or
the Notes: 
 (1)    Notes may be surrendered for conversion only after the Open of Business and before
the Close of Business on a day that is a Business Day; 
 (2)    in no event may any Note be converted
after the Close of Business on the Scheduled Trading Day immediately before the Maturity Date; 

(3)    if the Company calls any Note for Redemption pursuant to Section 4.03,
then the Holder of such Note may not convert such Note after the Close of Business on the Business Day immediately before the applicable Redemption Date, except to the extent the Company fails to pay the Redemption Price for such Note in accordance
with the Indenture; and 

  
 - 39 - 













 (4)    if a Fundamental Change Repurchase Notice is
validly delivered pursuant to Section 4.02(F) with respect to any Note, then such Note may not be converted, except to the extent (a) such Note is not subject to such notice; (b) such notice is withdrawn in
accordance with Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with the Indenture. 

Section 5.02.    CONVERSION PROCEDURES. 

(A)    Generally. 

(i)    Global Notes. To convert a beneficial interest in a Global Note that is convertible pursuant
to Section 5.01(C), the owner of such beneficial interest must (1) comply with the Depositary Procedures for converting such beneficial interest (at which time such conversion will become irrevocable); and (2) pay
any amounts due pursuant to Section 5.02(D) or Section 5.02(E). 

(ii)    Physical Notes. To convert all or a portion of a Physical Note that is convertible pursuant
to Section 5.01(C), the Holder of such Note must (1) complete, manually sign and deliver to the Conversion Agent the conversion notice attached to such Physical Note or a facsimile of such conversion notice;
(2) deliver such Physical Note to the Conversion Agent (at which time such conversion will become irrevocable); (3) furnish any endorsements and transfer documents that the Company or the Conversion Agent may require; and (4) pay any
amounts due pursuant to Section 5.02(D) or Section 5.02(E). 

(B)    Effect of Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion
thereof) to be converted, such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant to Section 5.03(B) or 5.02(D), upon such conversion) be
deemed to cease to be outstanding (and, for the avoidance of doubt, no Person will be deemed to be a Holder of such Note (or such portion thereof) as of the Close of Business on such Conversion Date), except to the extent provided in
Section 5.02(D). 
 (C)    Holder of Record of Conversion Shares. The Person in whose
name any share of Common Stock is issuable upon conversion of any Note will be deemed to become the holder of record of such share as of the Close of Business on (i) the Conversion Date for such conversion, in the case of Physical Settlement;
or (ii) the last VWAP Trading Day of the Observation Period for such conversion, in the case of Combination Settlement. 

(D)    Interest Payable upon Conversion in Certain Circumstances. If the Conversion Date of a Note is after a
Regular Record Date and before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such conversion (and, for the avoidance of doubt,
notwithstanding anything set forth in the proviso to this sentence), to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest
Payment Date (assuming, solely for these purposes, that such Note 

  
 - 40 - 













 
remained outstanding through such Interest Payment Date); and (ii) the Holder surrendering such Note for conversion must deliver to the Conversion Agent, at the time of such surrender, an
amount of cash equal to the amount of such interest referred to in clause (i) above; provided, however, that the Holder surrendering such Note for conversion need not deliver such cash (w) if the Company has specified a
Redemption Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; (x) if such Conversion Date occurs after the Regular Record Date immediately before the Maturity Date;
(y) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; or (z) to the extent of any overdue interest or
interest that has accrued on any overdue interest. For the avoidance of doubt, as a result of, and without limiting the generality of, the foregoing, if a Note is converted with a Conversion Date that is after the Regular Record Date immediately
before the Maturity Date, then the Company will pay, as provided above, the interest that would have accrued on such Note to, but excluding, the Maturity Date. For the avoidance of doubt, if the Conversion Date of a Note to be converted is on an
Interest Payment Date, then the Holder of such Note at the Close of Business on the Regular Record Date immediately before such Interest Payment Date will be entitled to receive, on or, at the Company’s election, before such Interest Payment
Date, the unpaid interest that has accrued on such Note to, but excluding, such Interest Payment Date, and such Note, when surrendered for conversion, need not be accompanied by any cash amount pursuant to the first sentence of this
Section 5.02(D). 
 (E)    Taxes and Duties. If a Holder converts a Note, the Company
will pay any documentary, stamp or similar issue or transfer tax or duty due on the issue or delivery of any shares of Common Stock upon such conversion; provided, however, that if any tax or duty is due because such Holder requested
such shares to be registered in a name other than such Holder’s name, then such Holder will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Conversion Agent may refuse to deliver any such shares to
be issued in a name other than that of such Holder. 
 (F)    Conversion Agent to Notify Company of Conversions.
If any Note is submitted for conversion to the Conversion Agent or the Conversion Agent receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly (and, in any event, no later than the date the Conversion Agent
receives such Note or notice) notify the Company and the Trustee of such occurrence, together with any other information reasonably requested by the Company, and will cooperate with the Company to determine the Conversion Date for such Note. 

Section 5.03.    SETTLEMENT UPON CONVERSION. 

(A)    Settlement Method. Upon the conversion of any Note, the Company will settle such conversion by paying or
delivering, as applicable and as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(1) (a
“Physical Settlement”); (y) solely cash as provided in Section 5.03(B)(i)(2) (a “Cash Settlement”); or (z) a combination of cash and shares of Common Stock, together, if applicable,
with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(3) (a “Combination Settlement”). 

  
 - 41 - 













 (i)    The Company’s Right to Elect Settlement
Method. The Company will have the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that: 

(1)    all conversions of Notes with a Conversion Date that occurs on or after April 1, 2025 will be
settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than the Open of Business on April 1, 2025; 

(2)    subject to clause (3) below, if the Company elects a Settlement Method with respect to
the conversion of any Note whose Conversion Date occurs before April 1, 2025, then the Company will send notice of such Settlement Method to the Holder of such Note, the Trustee and the Conversion Agent (if other than the Trustee) no later than
the Close of Business on the Business Day immediately after such Conversion Date; 
 (3)    if any Notes
are called for Redemption, then (1) the Company will specify, in the related Redemption Notice sent pursuant to Section 4.03(F), the Settlement Method that will apply to all conversions of Notes with a Conversion Date
that occurs on or after the related Redemption Notice Date and before the related Redemption Date; and (2) if such Redemption Date occurs on or after April 1, 2025, then such Settlement Method must be the same Settlement Method that,
pursuant to clause (1) above, applies to all conversions of Notes with a Conversion Date that occurs on or after April 1, 2025; 

(4)    the Company will use the same Settlement Method for all conversions of Notes with the same
Conversion Date (and, for the avoidance of doubt, the Company will not be obligated to use the same Settlement Method with respect to conversions of Notes with different Conversion Dates, except as provided in clause (1) or (3)
above); 
 (5)    if the Company does not timely elect a Settlement Method with respect to the conversion
of a Note, then the Company will be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default); 

(6)    if the Company timely elects Combination Settlement with respect to the conversion of a Note but
does not timely notify the Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the
failure to timely send such notification will not constitute a Default or Event of Default); and 

(7)    the Settlement Method will be subject to Sections 4.03(D), 5.09(A)(2) and
5.01(C)(i)(3)(a). 

  
 - 42 - 













 (ii)    The Company’s Right to
Irrevocably Fix the Settlement Method. The Company will have the right, exercisable at its election by sending notice of such exercise to the Holders (with a copy to the Trustee and the Conversion Agent (if other than the Trustee)), to
irrevocably fix the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders, provided that (x) such Settlement Method must be a Settlement
Method that the Company is then permitted to elect (for the avoidance of doubt, including pursuant to, and subject to, the other provisions of this Section 5.03(A)); (y) no such irrevocable election will affect any
Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to the other provisions of this Section 5.03(A); and (z) upon any such irrevocable election, the Default Settlement
Method will automatically be deemed to be set to the Settlement Method so fixed. Such notice, if sent, must set forth the applicable Settlement Method and expressly state that the election is irrevocable and applicable to all conversions of Notes
with a Conversion Date that occurs on or after the date such notice is sent to Holders. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the Indenture or the Notes, including pursuant to
Section 8.01(G) (it being understood, however, that the Company may nonetheless choose to execute such an amendment at its option). 

(iii)    Requirement to Publicly Disclose the Fixed or Default Settlement Method. If the Company
changes the Default Settlement Method pursuant to clause (x) of the proviso to the definition of such term or irrevocably fixes the Settlement Method pursuant Section 5.03(A)(ii), then the Company will either
post the Default Settlement Method or fixed Settlement Method, as applicable, on its website or disclose the same in a Current Report on Form 8-K (or any successor form) that is filed with the SEC. 

(B)    Conversion Consideration. 

(i)    Generally. Subject to Section 5.03(B)(ii) and
Section 5.03(B)(iii), the type and amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be as follows: 

(1)    if Physical Settlement applies to such conversion, a number of shares of Common Stock equal to the
Conversion Rate in effect on the Conversion Date for such conversion; 
 (2)    if Cash Settlement
applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each VWAP Trading Day in the Observation Period for such conversion; or 

(3)    if Combination Settlement applies to such conversion, consideration consisting of (a) a number
of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in
such Observation Period. 

  
 - 43 - 













 (ii)    Cash in Lieu of Fractional Shares. If
Physical Settlement or Combination Settlement applies to the conversion of any Note and the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such conversion is not a whole number, then such
number will be rounded down to the nearest whole number and the Company will deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such
fraction and (2) (x) the Daily VWAP on the Conversion Date for such conversion (or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on the
last VWAP Trading Day of the Observation Period for such conversion, in the case of Combination Settlement. 

(iii)    Conversion of Multiple Notes by a Single Holder. If a Holder converts more than one
(1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures) be computed based on
the total principal amount of Notes converted on such Conversion Date by such Holder. 

(iv)    Notice of Calculation of Conversion Consideration. If Cash Settlement or Combination
Settlement applies to the conversion of any Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter send notice
to the Trustee and the Conversion Agent of the same and the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such determination. 

(C)    Delivery of the Conversion Consideration. Except as set forth in Sections 5.05(A) and
5.09, the Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such conversion, on or before
the second (2nd) Business Day immediately after the last VWAP Trading Day of the Observation Period for such conversion; and (ii) if Physical Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after
the Conversion Date for such conversion; provided however, if Physical Settlement applies with respect to a conversion of any Note with a Conversion Date that is after the regular Record Date immediately before the Maturity Date, then, solely for
the purposes of such conversion, the Company will pay or deliver, as applicable, the consideration due upon such conversion no later than the Maturity Date (or, if the Maturity Date is not a Business Day, the next Business Day) and the Conversion
Date will instead be deemed to be the second Business Day immediately before the Maturity Date. 
 (D)    Deemed
Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a Holder converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and,
except as provided in Section 5.02(D), the Company’s delivery of the Conversion Consideration due in respect of such conversion will be deemed to fully satisfy and discharge the Company’s obligation to pay the
principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding the Conversion Date. As a result, except as provided in Section 5.02(D), any accrued and unpaid interest on a converted Note will be
deemed to be paid in full rather than cancelled, 

  
 - 44 - 













 
extinguished or forfeited. In addition, subject to Section 5.02(D), if the Conversion Consideration for a Note consists of both cash and shares of the Common Stock, then
accrued and unpaid interest that is deemed to be paid therewith will be deemed to be paid first out of such cash. 

Section 5.04.    RESERVE; STATUS OF COMMON STOCK
ISSUED UPON CONVERSION; COMPLIANCE WITH SECURITIES LAWS. 

(A)    Stock Reserve. At all times when any Notes are outstanding, the Company will reserve, out of its authorized
but unissued and unreserved shares of Common Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes, assuming (x) Physical Settlement will apply to such conversion; and (y) the
Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section 5.07. To the extent the Company delivers shares of Common Stock held in its treasury in
settlement of the conversion of any Notes, each reference in the Indenture or the Notes to the issuance of shares of Common Stock in connection therewith will be deemed to include such delivery, mutatis mutandis. 

(B)    Status of Conversion Shares; Listing. Each Conversion Share, if any, delivered upon conversion of any Note
will be a newly issued or treasury share (except that any Conversion Share delivered by a designated financial institution pursuant to Section 5.08 need not be a newly issued or treasury share) and will be duly and validly
issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such
Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company use will cause each Conversion Share, when delivered
upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system. 

Section 5.05.    ADJUSTMENTS TO THE CONVERSION RATE.

 (A)    Events Requiring an Adjustment to the Conversion Rate. The Conversion Rate will be adjusted from
time to time as follows: 
 (i)    Stock Dividends, Splits and Combinations. If the Company issues
solely 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 stock split or a stock combination of the Common Stock (in each case excluding an issuance solely
pursuant to a Common Stock Change Event, as to which Section 5.09 will apply), then the Conversion Rate will be adjusted based on the following formula: 

 

					
	 CR1 = CR0 ×
	 	 OS1
	  	
	 	OS0	  	


  
 - 45 - 














					
	where:	 		  	
			
	CR0	 	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately before the Open of Business on the effective
date of such stock split or stock combination, as applicable;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or effective date, as applicable;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as applicable, without giving effect to such dividend,
distribution, stock split or stock combination; and
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination.

 For the avoidance of doubt, any adjustment to the Conversion Rate pursuant to this
Section 5.05(A)(i) will become effective as of the time set forth in the definition of CR1 above. If any dividend, distribution, stock split or stock
combination of the type described in this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to
pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced. 

(ii)    Rights, Options and Warrants. If the Company distributes, to all or substantially all
holders of Common Stock, rights, options or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which Sections 5.05(A)(iii)(1) and 5.05(F) will apply) entitling such holders, for a
period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of
Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula: 

 

					
	CR1 = CR0 ×	 	 OS + X
	  	
	 	OS + Y	  	

  

					
	where:	 		  	
			
	CR0	 	=	  	the Conversion Rate in effect immediately before 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;


  
 - 46 - 














					
			
	OS	 	=	  	the number of shares of Common Stock outstanding immediately before 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	 	=	  	a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten
(10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced.

 Any adjustment to the Conversion Rate pursuant to this Section 5.05(A)(ii) will be
made successively whenever any such rights, options or warrants are distributed and, for the avoidance of doubt, will become effective as of the time set forth in the definition of CR1
above. To the extent such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been
made on the basis of only the rights, options or warrants, if any, actually distributed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such
rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the
number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants. 
 For purposes of this
Section 5.05(A)(ii) and Section 5.01(C)(i)(3)(a)(I), in determining whether any rights, options or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at a
price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date the distribution of such
rights, options or warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and
any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Board of Directors. 

(iii)    Spin-Offs and Other Distributed Property. 

(1)    Distributions Other than Spin-Offs. If the Company distributes shares of its Capital Stock,
evidences of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding: 

(u)    dividends, distributions, rights, options or warrants for which an adjustment to the Conversion
Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(i) or 5.05(A)(ii); 

  
 - 47 - 













 (v)    dividends or distributions paid exclusively in
cash for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv); 

(w)    rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent
provided in Section 5.05(F); 
 (x)    Spin-Offs for which an adjustment to
the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iii)(2); 

(y)    a distribution solely pursuant to a tender offer or exchange offer for shares of Common Stock, as
to which Section 5.05(A)(v) will apply; and 
 (z)    a distribution solely
pursuant to a Common Stock Change Event, as to which Section 5.09 will apply, 
 then the
Conversion Rate will be increased based on the following formula: 
  

					
	CR1 = CR0 ×	  	 SP
	  	
	  	SP – FMV 	  	

  

					
	where:
			
	CR0	 	=	  	the Conversion Rate in effect immediately before 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;
			
	SP	 	=	  	the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before such
Ex-Dividend Date; and
			
	FMV	 	=	  	the fair market value (as determined by the Board of Directors), as of such Ex-Dividend Date, of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or
warrants distributed per share of Common Stock pursuant to such distribution.


  
 - 48 - 













 For the avoidance of doubt, any adjustment to the Conversion Rate pursuant to this
Section 5.05(A)(iii)(2) will become effective as of the time set forth in the definition of CR1 above. However, if FMV is equal to or greater than
SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as
holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number of shares
of Common Stock equal to the Conversion Rate in effect on such record date. 
 To the extent such distribution is not so paid or made, the
Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid. 

(2)    Spin-Offs. If the Company distributes or dividends shares of Capital Stock of any class or
series, or similar equity interests, of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock (other than solely pursuant to (x) a Common Stock Change Event, as
to which Section 5.09 will apply; or (y) a tender offer or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply), and such Capital Stock or equity interests are
listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), then the Conversion Rate will be increased
based on the following formula: 
  

					
	CR1 = CR0 ×	 	 FMV + SP 
	  	
	 	 SP
	  	

  

					
	where:
			
	CR0	 	=	  	the Conversion Rate in effect immediately before 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 such Ex-Dividend Date;
			
	FMV	 	=	  	the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital Stock or equity interests distributed in such Spin-Off over the ten (10) consecutive Trading Day period (the
“Spin-Off Valuation Period”) beginning on, and including, such Ex-Dividend Date (such average to be determined as if references to Common Stock in the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event
were instead references to such Capital Stock or equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in such Spin-Off; and
			
	SP	 	=	  	the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the Spin-Off Valuation Period.


  
 - 49 - 













 The adjustment to the Conversion Rate pursuant to this
Section 5.05(A)(iii)(2) will be calculated as of the Close of Business on the last Trading Day of the Spin-Off Valuation Period but will be given effect immediately after the Open of
Business on the Ex-Dividend Date for the Spin-Off, with retroactive effect. If a Note is converted and the Conversion Date (in the case of Physical Settlement) or any
VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs during the Spin-Off Valuation Period, then, notwithstanding anything to the contrary in
the Indenture or the Notes, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Spin-Off Valuation Period. 

To the extent any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not
made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid. 

(iv)    Cash Dividends or Distributions. If any cash dividend or distribution is made to all or
substantially all holders of Common Stock, then the Conversion Rate will be increased based on the following formula: 
  

					
	CR1 = CR0 ×	 	 SP
	  	
	 	SP – D 	  	

  

					
	where:
			
	CR0	 	=	  	the Conversion Rate in effect immediately before 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 such Ex-Dividend Date;
			
	SP	 	=	  	the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date; and
			
	D	 	=	  	the cash amount distributed per share of Common Stock in such dividend or distribution;


  
 - 50 - 













 provided, however, that if D is equal to or greater than SP,
then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as
holders of Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. 

To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate
that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid. 

(v)    Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment
in respect of a tender offer or exchange offer for shares of Common Stock (other than solely pursuant to an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under the
Exchange Act), and the value (determined as of the Expiration Time by the Board of Directors) of the cash and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per share of
Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be
increased based on the following formula: 
  

					
	CR1 = CR0 ×	 	 AC + (SP × OS1)
	  	
	 	SP × OS0	  	

  

					
	where:	 		  	
			
	CR0	 	=	  	the Conversion Rate in effect immediately before the time (the “Expiration Time”) such tender or exchange offer expires;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the Expiration Time;
			
	AC	 	=	  	the aggregate value (determined as of the Expiration Time by the Board of Directors) of all cash and other consideration paid for shares of Common Stock purchased or exchanged in such tender or exchange offer;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
			
	SP	 	=	  	the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading
Day immediately after the Expiration Date;


  
 - 51 - 













 provided, however, that the Conversion Rate will in no event be adjusted down
pursuant to this Section 5.05(A)(v), except to the extent provided in the immediately following paragraph. The adjustment to the Conversion Rate pursuant to this Section 5.05(A)(v) will be
calculated as of the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period but will be given effect immediately after the Expiration Time, with retroactive effect. If a Note is converted and the Conversion Date (in
the case of Physical Settlement) or any VWAP Trading Day of the applicable Observation Period (in the case of Cash Settlement or Combination Settlement) occurs on the Expiration Date or during the Tender/Exchange Offer Valuation Period, then,
notwithstanding anything to the contrary in the Indenture or the Notes, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Tender/Exchange Offer Valuation Period.

 To the extent such tender or exchange offer is announced but not consummated (including as a result of the Company being precluded from
consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then
be in effect had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer. 

(B)    No Adjustments in Certain Cases. 

(i)    Where Holders Participate in the Transaction or Event Without Conversion. Notwithstanding
anything to the contrary in Section 5.05(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to
Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in
Section 5.05(A)(v)) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having to convert
such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date; and (ii) the aggregate principal amount (expressed in thousands)
of Notes held by such Holder on such date. 

  
 - 52 - 













 (ii)    Certain Events. The Company will not be
required to adjust the Conversion Rate except as provided in Section 5.05 or Section 5.07. Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account
of: 
 (1)    except as otherwise provided in Section 5.05, the sale of shares
of Common Stock for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price; 

(2)    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 such plan; 

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

(4)    the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or
exchangeable security of the Company outstanding as of the Issue Date; 
 (5)    solely a change in the
par value of the Common Stock; or 
 (6)    accrued and unpaid interest on the Notes. 

(C)    Adjustment Deferral. If an adjustment to the Conversion Rate otherwise required by this Article 5
would result in a change of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5, the Company may, at its election, defer such adjustment, except that all such deferred
adjustments must be given effect immediately upon the earliest of the following: (i) when all such deferred adjustments would result in a change of at least one percent (1%) to the Conversion Rate; (ii) the Conversion Date (in the case of
Physical Settlement) of, or any VWAP Trading Day of an Observation Period (in the case of Cash Settlement or Combination Settlement) for, any Note; (iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; (iv) the date
the Company calls any Notes for Redemption; and (v) April 1, 2025. 
 (D)    Adjustments Not Yet
Effective. Notwithstanding anything to the contrary in the Indenture or the Notes, if: 
 (i)    a
Note is to be converted pursuant to Physical Settlement or Combination Settlement; 
 (ii)    the record
date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to Section 5.05(A) has occurred on or before the Conversion Date for such conversion (in the case of Physical
Settlement) or on or before any VWAP Trading Day in the Observation Period for such conversion (in the case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date
or VWAP Trading Day, as applicable; 

  
 - 53 - 













 (iii)    the Conversion Consideration due upon such
conversion includes any whole shares of Common Stock (in the case of Physical Settlement) or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement); and 

(iv)    such shares are not entitled to participate in such event (because they were not held on the
related record date or otherwise), 
 then, solely for purposes of such conversion, the Company will, without duplication, give effect to such adjustment on
such Conversion Date (in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement). In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is
before the first date on which the amount of such adjustment can be determined, then the Company will delay the settlement of such conversion until the second (2nd) Business Day after such first date. 

(E)    Conversion Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event.
Notwithstanding anything to the contrary in the Indenture or the Notes, if: 
 (i)    a Conversion Rate
adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A); 

(ii)    a Note is to be converted pursuant to Physical Settlement or Combination Settlement; 

(iii)    the Conversion Date for such conversion (in the case of Physical Settlement) or any VWAP Trading
Day in the Observation Period for such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record date; 

(iv)    the Conversion Consideration due upon such conversion includes any whole shares of Common Stock (in
the case of Physical Settlement) or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement), in each case based on a Conversion Rate that is adjusted for such dividend
or distribution; and 
 (v)    such shares would be entitled to participate in such dividend or
distribution (including pursuant to Section 5.02(C)), 
 then (x) in the case of Physical Settlement, such Conversion Rate
adjustment will not be given effect for such conversion and the shares of Common Stock issuable upon such conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or distribution, but there will be
added, to the Conversion Consideration otherwise due upon such conversion, the same kind and amount of consideration that would have been delivered in such 

  
 - 54 - 













 
dividend or distribution with respect to such shares of Common Stock had such shares been entitled to participate in such dividend or distribution; and (y) in the case of Combination
Settlement, the Conversion Rate adjustment relating to such Ex-Dividend Date will be made for such conversion in respect of such VWAP Trading Day, but the shares of Common Stock issuable with respect to such
VWAP Trading Day based on such adjusted Conversion Rate will not be entitled to participate in such dividend or distribution.  

(F)    Stockholder Rights Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at
the time of such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under
the Indenture upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to
Section 5.05(A)(iii)(1) on account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to
readjustment in accordance with such Section if such rights expire, terminate or are redeemed. 
 (G)    Limitation
on Effecting Transactions Resulting in Certain Adjustments. The Company will not engage in or be a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or
Section 5.07 to an amount that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock. 

(H)    Equitable Adjustments to Prices. Whenever any provision of the Indenture requires the Company to calculate
the average of the Last Reported Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), or to calculate Daily VWAPs over an Observation Period, the
Company will make proportionate adjustments, if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A)(i) that becomes effective, or any event requiring such an adjustment
to the Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during such period or Observation Period, as applicable. 

(I)    Calculation of Number of Outstanding Shares of Common Stock. For purposes of
Section 5.05(A), the number of shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock; and
(ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury). 

(J)    Calculations. All calculations with respect to the Conversion Rate and adjustments thereto will be made to
the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward). 
 (K)    Certain Notices.
(i) Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section 5.05(A), the Company will promptly send notice to the Holders, the 

  
 - 55 - 













 
Trustee and the Conversion Agent (if other than the Trustee) containing (1) a brief description of the transaction or other event on account of which such adjustment was made; (2) the
Conversion Rate in effect immediately after such adjustment; and (3) the effective time of such adjustment. 

Section 5.06.    VOLUNTARY ADJUSTMENTS. 

(A)    Generally. To the extent permitted by law and applicable stock exchange rules, the Company, from time to
time, may (but is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any
income tax imposed on holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event; (ii) such increase is in effect for a
period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such period. 

(B)    Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant
to Section 5.06(A), then, no later than the first Business Day of the related twenty (20) Business Day period referred to in Section 5.06(A), the Company will send notice to each Holder, the
Trustee and the Conversion Agent of such increase, the amount thereof and the period during which such increase will be in effect. 

Section 5.07.    ADJUSTMENTS TO THE CONVERSION RATE
IN CONNECTION WITH A MAKE-WHOLE FUNDAMENTAL CHANGE. 

(A)    Generally. If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note
occurs during the related Make-Whole Fundamental Change Conversion Period, then, subject to this Section 5.07, the Conversion Rate applicable to such conversion will be increased by a number of shares (the
“Additional Shares”) set forth in the table below corresponding (after interpolation as provided in, and subject to, the provisions below) to the Make-Whole Fundamental Change Effective Date and the Stock Price of such Make-Whole
Fundamental Change:

 If such Make-Whole Fundamental Change Effective Date or Stock Price is not set forth in the
table above, then: 
 (i)    if such Stock Price is between two Stock Prices in the table above or the
Make-Whole Fundamental Change Effective Date is between two dates in the table above, then the number of Additional Shares will be determined by straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower
Stock Prices in the table above or the earlier and later dates in the table above, based on a 365- or 366-day year, as applicable; and 

(ii)    if the Stock Price is greater than $125.00 (subject to adjustment in the same manner as the Stock
Prices set forth in the column headings of the table above are adjusted pursuant to Section 5.07(B)), or less than $13.50 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the
Conversion Rate. 
 Notwithstanding anything to the contrary in the Indenture or the Notes, in no event will the Conversion Rate be
increased to an amount that exceeds 74.0740 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is
required to be adjusted pursuant to Section 5.05(A). 
 For the avoidance of doubt, but subject to
Section 4.03(I), (x) the sending of a Redemption Notice will constitute a Make-Whole Fundamental Change only with respect to the Notes called for Redemption pursuant to such Redemption Notice, and not with respect to any
other Notes; and (y) the Conversion Rate applicable to the Notes not so called for Redemption will not be subject to increase pursuant to this Section 5.07 on account of such Redemption Notice. 

(B)    Adjustment of Stock Prices and Number of Additional Shares. The Stock Prices in the first row (i.e.,
the column headers) of the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted as a result of the operation of
Section 5.05(A). The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the
Conversion Rate is adjusted pursuant to Section 5.05(A). 
 (C)    Notice of the Occurrence
of a Make-Whole Fundamental Change. The Company will notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of each Make-Whole Fundamental Change occurring pursuant to (i) clause (A) of the definition
thereof in accordance with Section 5.01(C)(i)(3)(b) and (ii) clause (B) of the definition thereof in accordance with Section 4.03(F). 

Section 5.08.    EXCHANGE IN LIEU OF CONVERSION.

 Notwithstanding anything to the contrary in this Article 5, and subject to the terms of this
Section 5.08, if a Note is submitted for conversion, the Company may elect to arrange to have 

  
 - 57 - 













 
such Note exchanged in lieu of conversion by a financial institution designated by the Company. To make such election, the Company must send notice of such election to the Holder of such Note,
the Trustee and the Conversion Agent (if other than the Trustee) before the Close of Business on the Business Day immediately following the Conversion Date for such Note. If the Company has made such election, then: 

(A)    no later than the Business Day immediately following such Conversion Date, the Company must deliver (or cause to be
delivered) such Note, together with delivery instructions for the Conversion Consideration due upon such conversion (including wire instructions, if applicable), to a financial institution designated by the Company that has agreed to deliver such
Conversion Consideration in the manner and at the time the Company would have had to deliver the same pursuant to this Article 5; 

(B)    if such Note is a Global Note, then (i) such designated institution will send written confirmation to the
Company promptly after wiring the cash Conversion Consideration, if any, and delivering any other Conversion Consideration, due upon such conversion to the Holder of such Note; and 

(C)    such Note will not cease to be outstanding by reason of such exchange in lieu of conversion; 

provided, however, that if such financial institution does not accept such Note or fails to timely deliver such Conversion Consideration, then
the Company will be responsible for delivering such Conversion Consideration in the manner and at the time provided in this Article 5 as if the Company had not elected to make an exchange in lieu of conversion. The Company, the Conversion
Agent and the Holders surrendering the Notes for conversion will cooperate to cause such Notes to be delivered to the designated financial institution and the Conversion Agent will be entitled to conclusively rely on the Company’s instructions
in connection with effecting any exchange election and will have no liability for such exchange election outside of its control. Any Notes exchanged by the designated financial institution will remain outstanding, notwithstanding the surrender of
such Notes and will be subject to the Depositary Procedures. 
 Section 5.09.    EFFECT OF
COMMON STOCK CHANGE EVENT. 
 (A)    Generally. If
there occurs any: 
 (i)    recapitalization, reclassification or change of the Common Stock (other than
(x) changes solely resulting from a subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock splits and stock combinations that do not
involve the issuance of any other series or class of securities); 
 (ii)    consolidation, merger,
combination or binding or statutory share exchange involving the Company; 
 (iii)    sale, lease or
other transfer of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any Person; or 

  
 - 58 - 













 (iv)    other similar event, 

and, as a result of which, the Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other
property, or any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash or property, the “Reference Property,” and the amount and kind of Reference Property that
a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other property), a
“Reference Property Unit”), then, notwithstanding anything to the contrary in the Indenture or the Notes, 

(1)    from and after the effective time of such Common Stock Change Event, (I) the Conversion
Consideration due upon conversion of any Note, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions)
were instead a reference to the same number of Reference Property Units; (II) for purposes of Section 4.03, each reference to any number of shares of Common Stock in such Section (or in any related definitions) will
instead be deemed to be a reference to the same number of Reference Property Units; and (III) for purposes of the definition of “Fundamental Change” and “Make-Whole Fundamental Change,” the terms “Common Stock” and
“common equity” will be deemed to mean the common equity (including depositary receipts representing common equity), if any, forming part of such Reference Property; 

(2)    if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect
Physical Settlement in respect of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event and will pay the cash due upon such conversions no later than the second (2nd) Business Day after the
relevant Conversion Date; and 
 (3)    for these purposes, (I) the Daily VWAP of any Reference
Property Unit or portion thereof that consists of a class of common equity securities will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg page for such class of securities in such
definition; and (II) the Daily VWAP of any Reference Property Unit or portion thereof that does not consist of a class of common equity securities, and the Last Reported Sale Price of any Reference Property Unit or portion thereof that does not
consist of a class of securities, will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). 

If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of stockholder
election, then the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock. The Company will notify
Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

 At or before the effective time of such Common Stock Change Event, the Company and the
resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture pursuant to
Section 8.01(F), which supplemental indenture will (x) provide for subsequent conversions of Notes in the manner set forth in this Section 5.09; (y) provide for subsequent adjustments to the
Conversion Rate pursuant to Section 5.05(A) in a manner consistent with this Section 5.09; and (z) contain such other provisions, if any, that the Company reasonably determines are appropriate
to preserve the economic interests of the Holders and to give effect to the provisions of this Section 5.09(A). If the Reference Property includes shares of stock or other securities or assets (other than cash) of a Person
other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions, if any, that the Company reasonably determines are appropriate to preserve
the economic interests of the Holders. 
 (B)    Notice of Common Stock Change Events. The Company will provide
notice of each Common Stock Change Event to Holders, the Trustee and the Conversion Agent no later than the second (2nd) Business Day after the effective date of such Common Stock Change Event. 

(C)    Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms
are consistent with this Section 5.09. 
 Section 5.10.    RESPONSIBILITY
OF THE TRUSTEE. 
 The Trustee and any other Conversion Agent will not at any time be under
any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent
or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent will not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, monitoring the Company’s Common Stock trading price or of any securities, property or cash that may at any time be issued or delivered upon the conversion
of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent will be responsible for any failure of the Company to issue, transfer or deliver any shares of
Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article
5. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent will be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to
Section 5.09 relating either to the kind or amount of shares of Common Stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such
Section 5.09 or to any adjustment to be made with respect thereto, but, subject to Section 7.1 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any
such provisions, and will be protected in relying upon, the Officer’s Certificate (which the Company will be obligated to file with the Trustee prior to the execution 

  
 - 60 - 













 
of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent will be responsible for determining whether any event contemplated by
Section 5.01(C) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in
Section 5.01(C) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely. 

Article 6.    SUCCESSORS 

Section 6.01.    WHEN THE COMPANY MAY MERGE,
ETC. 
 (A)    Generally. The Company will not consolidate with or merge with or into, or
(directly, or indirectly through one or more of its Subsidiaries) sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to
another Person (a “Business Combination Event”), unless: 
 (i)    the resulting,
surviving or transferee Person either (x) is the Company or (y) if not the Company, is (1) a corporation or (2) if such Business Combination Event constitutes an Exempted Fundamental Change, a corporation, partnership, limited
liability company or similar entity (in each case, the “Successor Entity”) duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that expressly assumes (by
executing and delivering to the Trustee, at or before the effective time of such Business Combination Event, a supplemental indenture pursuant to Section 8.01(E)) all of the Company’s obligations under the Indenture
and the Notes; and 
 (ii)    immediately after giving effect to such Business Combination Event, no
Default or Event of Default will have occurred and be continuing. 
 (B)    Delivery of Officer’s Certificate
and Opinion of Counsel to the Trustee. Before the effective time of any Business Combination Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such Business
Combination Event (and, if applicable, the related supplemental indenture) comply with Section 6.01(A); and (ii) all conditions precedent to such Business Combination Event provided in the Indenture have been
satisfied. 
 Section 6.02.    SUCCESSOR ENTITY SUBSTITUTED. 

At the effective time of any Business Combination Event that complies with Section 6.01, the Successor Entity (if not
the Company) will succeed to, and may exercise every right and power of, the Company under the Indenture and the Notes with the same effect as if such Successor Entity had been named as the Company in the Indenture and the Notes, and, except in the
case of a lease, the predecessor Company will be discharged from its obligations under the Indenture and the Notes. 

  
 - 61 - 













 Section 6.03.    WHEN THE GUARANTOR
MAY MERGE, ETC. 
 (A)    Generally. The Guarantor will not
consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Guarantor and its Subsidiaries, taken as a whole, to another Person (a
“Guarantor Business Combination Event”), unless: 
 (i)    the resulting, surviving or
transferee Person either (x) is the Guarantor or (y) if not the Guarantor, is a Person (the “Successor Guarantor Entity”) duly organized and existing under the laws of the United States of America, any State thereof or the
District of Columbia that expressly assumes (by executing and delivering to the Trustee, at or before the effective time of such Guarantor Business Combination Event, a supplemental indenture pursuant to Section 8.01(E))
all of the Guarantor’s obligations under the Notes or under the Indenture with respect to the Notes; and 

(ii)    immediately after giving effect to such Guarantor Business Combination Event, no Default or Event
of Default will have occurred and be continuing. 
 (B)    Delivery of Officer’s Certificate and
Opinion of Counsel to the Trustee. Before the effective time of any Guarantor Business Combination Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such Guarantor
Business Combination Event (and, if applicable, the related supplemental indenture) comply with Section 6.03(A); and (ii) all conditions precedent to such Guarantor Business Combination Event provided in the Indenture
have been satisfied. 
 (C)    Successor Guarantor Entity Substituted. At the effective time of any Guarantor
Business Combination Event that complies with Section 6.03(A) the Successor Guarantor Entity (if not the Guarantor) will succeed to, and may exercise every right and power of, the Guarantor under the Indenture and the Notes
with the same effect as if such Successor Guarantor Entity had been named as the Guarantor in the Indenture and the Notes, and, except in the case of a lease, the predecessor Guarantor will be discharged from its obligations under the Notes and
under the Indenture with respect to the Notes. 
 Section 6.04.    EXCLUSION FOR
ASSET TRANSFERS WITH WHOLLY OWNED SUBSIDIARIES. 

Notwithstanding anything to the contrary in this Article 6, this Article 6 will not apply to any transfer of assets between or
among the Company and any one or more of its Wholly Owned Subsidiaries not effected by merger or consolidation. 
 Article
7.    DEFAULTS AND REMEDIES 
 Section 7.01.    EVENTS OF
DEFAULT. 
 (A)    Definition of Events of Default. “Event of Default” means
the occurrence of any of the following: 
 (i)    a default in the payment when due (whether at maturity,
upon Redemption, Repurchase Upon Fundamental Change or otherwise) of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, any Note; 

  
 - 62 - 













 (ii)    a default for thirty (30) consecutive days
in the payment when due of interest on any Note; 
 (iii)    the Company’s failure to deliver, when
required by the Indenture, a Fundamental Change Notice, or a notice pursuant to Section 5.01(C)(i)(3), if (in the case of any notice other than a notice pursuant to Section 5.01(C)(i)(3)(a)) such
failure is not cured within five (5) Business Days after its occurrence; 
 (iv)    a default in the
Company’s obligation to convert a Note in accordance with Article 5 upon the exercise of the conversion right with respect thereto, if such default is not cured within five (5) Business Days after its occurrence;

obligations under Section 6.03; 
 (vi)    a default in any of the
Company’s obligations or agreements, or in the Guarantor’s obligations or agreements, under the Indenture or the Notes (other than a default set forth in clause (i), (ii), (iii), (iv) or
(v) of this Section 7.01(A)) where such default is not cured or waived within sixty (60) days after notice to the Company by the Trustee, or to the Company and the Trustee by Holders of at least twenty five
percent (25%) of the aggregate principal amount of Notes then outstanding, which notice must specify such default, demand that it be remedied and state that such notice is a “Notice of Default”; 

(vii)    a default by the Company or the Guarantor with respect to any one or more mortgages, agreements or
other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least one hundred fifty million dollars ($150,000,000) (or its foreign currency equivalent) in the aggregate of
the Company or the Guarantor, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default: 

(1)    constitutes a failure to pay the principal of such indebtedness when due and payable at its stated
maturity, upon required repurchase, upon declaration of acceleration or otherwise, in each case after the expiration of any applicable grace period; or 

(2)    results in such indebtedness becoming or being declared due and payable before its stated maturity,

 in each case where such default is not cured or waived within thirty (30) days after notice to the Company by the Trustee or to the
Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding; 

(viii)    the Guarantee ceases to be in full force and effect or the Guarantor denies or disaffirms in
writing its obligations under its Guarantee; 

  
 - 63 - 













 (ix)    the Company, the Guarantors, or any of their
respective Significant Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either: 

(1)    commences a voluntary case or proceeding; 

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

(3)    consents to the appointment of a custodian of it or for any substantial part of its property; 

(4)    makes a general assignment for the benefit of its creditors; or 

(5)    consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it;
or 
 (x)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that
either: 
 (1)    is for relief against the Company, the Guarantor or any of their respective Significant
Subsidiaries in an involuntary case or proceeding; or 
 (2)    appoints a custodian of the Company, the
Guarantor, or any of their respective Significant Subsidiaries, or for any substantial part of the property of the Company, the Guarantors, or any of their respective Significant Subsidiaries; 

(3)    orders the winding up or liquidation of the Company, the Guarantor, or any of their respective
Significant Subsidiaries, 
 and, in each case under this Section 7.01(A)(x), such order or decree remains unstayed
and in effect for at least sixty (60) days. 
 (B)    Cause Irrelevant. Each of the events set forth in
Section 7.01(A) will constitute an Event of Default regardless of the cause thereof or whether voluntary or involuntary or 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. 
 Section 7.02.    ACCELERATION. 

(A)    Automatic Acceleration in Certain Circumstances. If an Event of Default set forth in
Section 7.01(A)(ix) or 7.01(A)(x) occurs with respect to the Company or the Guarantor (and not solely with respect to a Significant Subsidiary of the Company or the Guarantor), then the principal amount of, and all
accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any Person. 

(B)    Optional Acceleration. Subject to Section 7.03, if an Event of Default (other than
an Event of Default set forth in Section 7.01(A)(ix) or 7.01(A)(x) with respect to the Company 

  
 - 64 - 













 
or the Guarantor and not solely with respect to a Significant Subsidiary of the Company or the Guarantor) occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at
least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding to
become due and payable immediately. 
 (C)    Rescission of Acceleration. Notwithstanding anything to the
contrary in the Indenture or the Notes, the Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind any acceleration of the Notes and its
consequences if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal
of, or interest on, the Notes that has become due solely because of such acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto. 

Section 7.03.    SOLE REMEDY FOR A FAILURE
TO REPORT. 
 (A)    Generally. Notwithstanding anything to the contrary in the
Indenture or the Notes, the Company may elect that the sole remedy for any Event of Default pursuant to Section 7.01(A)(vi) arising from the Company’s failure to comply with Section 3.02
(including the Company’s obligations under Section 314(a)(1) of the Trust Indenture Act) (a “Reporting Event of Default”) will, for each of the first three hundred and sixty five (365) calendar days on which a
Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant to
Section 7.02 on account of the relevant Reporting Event of Default from, and including, the three hundred and sixty sixth (366th) calendar day on which a Reporting Event of Default has occurred and is continuing or if the
Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease to accrue on any Notes from, and including, such three hundred and sixty sixth (366th) calendar day (it being understood that interest
on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.05(B)). 

(B)    Amount and Payment of Special Interest. Any Special Interest that accrues on a Note pursuant to
Section 7.03(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof
for the first one hundred and eighty (180) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof. However, in no event will Special Interest accrue
on any day on a Note at a combined rate per annum that exceeds 0.50%. For the avoidance of doubt, any Special Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note. 

(C)    Notice of Election. To make the election set forth in Section 7.03(A), the Company
must send to the Holders, the Trustee and the Paying Agent, before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly describes the report(s) that the Company failed to file with the SEC; (ii) states
that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) 

  
 - 65 - 













 
briefly describes the periods during which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account of such Reporting
Event of Default. 
 (D)    Notice to Trustee and Paying Agent; Trustee’s Disclaimer. If Special Interest
accrues on any Note, then, no later than five (5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the
Company is obligated to pay Special Interest on such Note on such date of payment; and (ii) the amount of such Special Interest that is payable on such date of payment. The Trustee will have no duty to determine whether any Special Interest is
payable or the amount thereof. 
 (E)    No Effect on Other Events of Default. No election pursuant to this
Section 7.03 with respect to a Reporting Event of Default will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other Reporting Event of Default. 

Section 7.04.    OTHER REMEDIES. 

(A)    Trustee May Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue
any available remedy to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of the Indenture or the Notes. 

(B)    Procedural Matters. The Trustee may maintain a proceeding even if it does not possess any of the Notes or
does not produce any of them in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default will not impair the right or remedy or constitute a waiver of, or acquiescence in, such
Event of Default. All remedies will be cumulative to the extent permitted by law. 
 Section 7.05.    WAIVER
OF PAST DEFAULTS. 
 An Event of Default pursuant to clause (i), (ii),
(iv) or (vi) of Section 7.01(A) (that, in the case of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent of each affected Holder), and a
Default that could lead to such an Event of Default, can be waived only with the consent of each affected Holder. Each other Default or Event of Default may be waived, on behalf of all Holders, by the Holders of a majority in aggregate principal
amount of the Notes then outstanding. If an Event of Default is so waived, then it will cease to exist. If a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur. However, no
such waiver will extend to any subsequent or other Default or Event of Default or impair any right arising therefrom. 

Section 7.06.    CONTROL BY MAJORITY. 

Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law, the Indenture or the Notes, or that,


  
 - 66 - 













 
subject to Section 7.1 of the Base Indenture, the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the Trustee is
offered and if requested, provided security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction (it being understood that the Trustee does
not have an affirmative duty to determine whether any direction is prejudicial to any Holder). 

Section 7.07.    LIMITATION ON SUITS. 

No Holder may pursue any remedy with respect to the Indenture or the Notes (except to enforce (x) its rights to receive any payment or
delivery, as applicable, of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or interest on, any Notes; or (y) the Company’s obligations to convert any Notes pursuant to Article 5), unless: 

(A)    such Holder has previously delivered to the Trustee notice that an Event of Default is continuing; 

(B)    Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a
request to the Trustee to pursue such remedy; 
 (C)    such Holder or Holders offer and, if requested, provide to the
Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such request; 

(D)    the Trustee does not comply with such request within sixty (60) calendar days after its receipt of such
request and such offer of security or indemnity; and 
 (E)    during such sixty (60) calendar day period, Holders
of a majority in aggregate principal amount of the Notes then outstanding do not deliver to the Trustee a direction that is inconsistent with such request. 

A Holder of a Note may not use the Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another
Holder. The Trustee will have no duty to determine whether any Holder’s use of the Indenture complies with the preceding sentence. 

Section 7.08.    ABSOLUTE RIGHT OF HOLDERS TO
RECEIVE PAYMENT AND CONVERSION CONSIDERATION AND TO INSTITUTE SUIT FOR THE
ENFORCEMENT OF SUCH RIGHT. 
 Notwithstanding anything to the contrary in the
Indenture or the Notes (but without limiting Section 8.01), the right of each Holder of a Note to receive payment or delivery, as applicable, of the principal of, or the Redemption Price or Fundamental Change Repurchase
Price for, or any interest on, or the Conversion Consideration due pursuant to Article 5 upon conversion of, such Note on or after the respective due dates therefor provided in the Indenture and the Notes, or to bring suit for the enforcement
of any such payment or delivery after such respective due dates, will not be impaired or affected without the consent of such Holder. 

  
 - 67 - 













 Section 7.09.    COLLECTION SUIT BY
TRUSTEE. 
 The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to
clause (i), (ii) or (iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or
Redemption Price or Fundamental Change Repurchase Price for, or interest on, or Conversion Consideration due pursuant to Article 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted
Amounts, and such further amounts sufficient to cover the costs and expenses of collection, including compensation provided for in Section 7.7 of the Base Indenture. 

Section 7.10.    TRUSTEE MAY FILE PROOFS OF
CLAIM. 
 The Trustee has the right to (A) file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes) or its creditors or property and (B) collect, receive and
distribute any money or other property payable or deliverable on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the making of such payments directly to
the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant to
Section 7.7 of the Base Indenture. To the extent that the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured
by a lien on, and will be 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 in the Indenture will be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes 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 7.11.    PRIORITIES. 

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7: 

First:    to the Trustee and its agents and attorneys for amounts due under Section 7.7 of the
Base Indenture, including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second:     to Holders for unpaid amounts or other property due on the Notes, including the
principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or any interest on, or any Conversion Consideration due upon conversion of, the Notes, ratably, and without preference or priority of any kind, according to such
amounts or other property due and payable on all of the Notes; and 

  
 - 68 - 













 Third:    to the Company or such other Person as
a court of competent jurisdiction directs. 
 The Trustee may fix a record date and payment date for any payment or delivery to the Holders
pursuant to this Section 7.11, in which case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the Trustee a notice
stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable. 

Section 7.12.    UNDERTAKING FOR COSTS. 

In any suit for the enforcement of any right or remedy under the Indenture or the Notes or in any suit against the Trustee for any action taken
or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking to pay the costs of such suit, and (B) assess reasonable costs (including reasonable attorneys’
fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided, however, that this Section 7.12 does not apply to
any suit by the Trustee, any suit by a Holder pursuant to Section 7.08 or any suit by one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding. 

Section 7.13.    TRUSTEE’S OBLIGATION TO PROVIDE
NOTICE OF DEFAULTS TO HOLDERS. 
 If a Default or Event of
Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, then the Trustee will send Holders a notice of such Default or Event of Default within ninety (90) days after it occurs or, if it is not actually
known to the Trustee at such time, promptly (and in any event within ten (10) Business Days) after it becomes actually known to a Responsible Officer of the Trustee; provided, however, that, except in the case of a Default or
Event of Default in the payment of the principal of, or interest on, any Note, the Trustee may withhold such notice if and for so long as it in good faith determines that withholding such notice is in the interests of the Holders. 

Article 8.     AMENDMENTS, SUPPLEMENTS AND WAIVERS 

Section 8.01.    WITHOUT THE CONSENT OF HOLDERS.

 Notwithstanding anything to the contrary in Section 8.02, the Company, the Guarantor and the Trustee may

(L)    comply with any requirement of the SEC in connection with effecting or maintaining the qualification of the
Indenture, or any supplemental indenture thereto, under the Trust Indenture Act, as then in effect; or

any other change to the Indenture or the Notes that does not, individually or in the aggregate with all other such changes, adversely affect the rights of the Holders, as such, in any material respect.

“Description of Notes” section and pricing term sheet referred to in Section 8.01(I).

 Section 8.02.    WITH THE CONSENT
OF HOLDERS. 
 (A)    Generally. Subject to Sections 8.01, 7.05
and 7.08 and the immediately following sentence, the Company, the Guarantor and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement the Indenture or
the Notes or waive compliance with any provision of the Indenture or the Notes. Notwithstanding anything to the contrary in the foregoing sentence, but subject to Section 8.01, without the consent of each affected Holder,
no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may: 

(i)    reduce the principal, or extend the stated maturity, of any Note; 

(ii)    reduce the Redemption Price or Fundamental Change Repurchase Price for any Note or change the times
at which, or the circumstances under which, the Notes may or will be redeemed or repurchased by the Company; 

(iii)    reduce the rate, or extend the time for the payment of interest on any Note; 

(iv)    make any change that adversely affects the conversion rights of any Note; 

(v)    impair the rights of any Holder set forth in Section 7.08 (as such section
is in effect on the Issue Date); 
 (vi)    change the ranking of the Notes or the Guarantee; 

(vii)     release the Guarantee of the Guarantor or modify or amend the terms and conditions of the
obligations of the Guarantor, as guarantor of the Notes, in any manner that is adverse to the rights of the Holders, as such, other than any elimination of the Guarantee in accordance with the Indenture; 

(viii)    make any Note payable in money, or at a place of payment, other than that stated in the Indenture
or the Note; 
 (ix)    reduce the amount of Notes whose Holders must consent to any amendment,
supplement, waiver or other modification; or 
 (x)    make any direct or indirect change to any
amendment, supplement, waiver or modification provision of the Indenture or the Notes that requires the consent of each affected Holder. 

For the avoidance of doubt, pursuant to clauses (i), (ii), (iii) and (iv) of this
Section 8.02(A), no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may change the amount or type of consideration due on any Note (whether on an Interest
Payment Date, Redemption Date, Fundamental Change Repurchase Date or the Maturity Date or upon conversion, or otherwise), or the date(s) or time(s) such consideration is payable or deliverable, as applicable, without the consent of each affected
Holder. 
 (B)    Holders Need Not Approve the Particular Form of any Amendment. A consent of any Holder pursuant
to this Section 8.02 need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver. 

  
 - 71 - 













 Section 8.03.    NOTICE OF
AMENDMENTS, SUPPLEMENTS AND WAIVERS. 
 As soon as reasonably practicable
after any amendment, supplement or waiver pursuant to Section 8.01 or 8.02 becomes effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement
or waiver in reasonable detail and (B) states the effective date thereof; provided, however, that the Company will not be required to provide such notice to the Holders if such amendment, supplement or waiver is included in a
periodic report filed by the Company with the SEC within four (4) Business Days of its effectiveness. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of such amendment, supplement or
waiver. 
 Section 8.04.    REVOCATION, EFFECT AND SOLICITATION
OF CONSENTS; SPECIAL RECORD DATES; ETC. 

(A)    Revocation and Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver
will bind (and constitute the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting Holder’s Note, subject to the right of any Holder of a Note to revoke (if not
prohibited pursuant to Section 8.04(B)) any such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement or waiver becomes effective. 

(B)    Special Record Dates. The Company may, but is not required to, fix a record date for the purpose of
determining the Holders entitled to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8. If a record date is fixed, then, notwithstanding anything to the contrary in
Section 8.04(A), only Persons who are Holders as of such record date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of
whether such Persons continue to be Holders after such record date; provided, however, that no such consent will be valid or effective for more than one hundred and twenty (120) calendar days after such record date. 

(C)    Solicitation of Consents. For the avoidance of doubt, each reference in the Indenture or the Notes to the
consent of a Holder will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes. 

(D)    Effectiveness and Binding Effect. Each amendment, supplement or waiver pursuant to this Article 8
will become effective in accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder of such Note (or such portion). 

Section 8.05.    NOTATIONS AND EXCHANGES. 

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder
of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in


  
 - 72 - 













 
exchange for such Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Note that reflects the changed
terms. The failure to make any appropriate notation or issue a new Note pursuant to this Section 8.05 will not impair or affect the validity of such amendment, supplement or waiver. 

Section 8.06.    TRUSTEE TO EXECUTE SUPPLEMENTAL
INDENTURES. 
 The Trustee will execute and deliver any amendment or supplemental indenture authorized pursuant to this
Article 8; provided, however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental indenture that adversely affects the Trustee’s rights, duties,
liabilities or immunities. In executing any amendment or supplemental indenture, the Trustee will be entitled to receive, and (subject to Sections 7.1 and 7.2 of the Base Indenture) will be fully protected in relying on, an Officer’s
Certificate and an Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted by the Indenture; and (B) in the case of the Opinion of Counsel, such amendment or
supplemental indenture is valid, binding and enforceable against the Company in accordance with its terms. 
 Article 9.
    GUARANTEES 
 Section 9.01.    GUARANTEES. 

(A)    Subject to the provisions of this Article 9, the Guarantor hereby fully, unconditionally and irrevocably
guarantees, as primary obligor and not merely as surety, on a joint and several basis, to each Holder of the Notes and the Trustee the due and punctual payment of the principal of, any interest on, and any Conversion Consideration for, the Notes
will be promptly paid in full when due whether at maturity, by acceleration, on a Fundamental Change Repurchase Date, upon Redemption or otherwise and interest on the overdue principal of, any interest on, or any Conversion Consideration for, the
Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee under the Notes, or under the Indenture with respect to the Notes, will promptly be paid or delivered in full or performed, as applicable, in each case in
accordance with the Indenture and the Notes (collectively, the “Guarantee Obligations”) in each case subject to Section 9.02. The Guarantor agrees that the Guarantee Obligations will rank equally in right
of payment with other indebtedness of the Guarantor, except to the extent such other indebtedness is subordinate to the Guarantee Obligations, in which case the obligations of the Guarantor under the Guarantee will rank senior in right of payment to
such other indebtedness, and except for claims of creditors that are mandatorily preferred by law, in which case the obligations of the Guarantor under the Guarantee will rank junior in right of payment to such claims. 

(B)    To evidence its Guarantee set forth in this Section 9.01, the Guarantor hereby agrees
that this Indenture (or a supplement thereto) shall be executed on behalf of the Guarantor by an Officer of the Guarantor. 

(C)    The Guarantor hereby agrees that its Guarantee set forth in this Section 9.01 hereof
shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. 

  
 - 73 - 













 (D)    If an Officer whose signature is on this Indenture (or a
supplement thereto) or any notation of Guarantee no longer holds that office at the time the Trustee authenticates a Note, the Guarantee of such Note shall be valid nevertheless. 

(E)    The Guarantor further agrees (to the extent permitted by law) that the Guarantee Obligations may be extended or
renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Section 9.01 notwithstanding any extension or renewal of any Guarantee Obligation. 

(F)    The Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guarantee
Obligations and also waives notice of protest for nonpayment. The Guarantor waives notice of any default under the Notes or the Guarantee Obligations. 

(G)    The Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment when due (and not a
guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guarantee Obligations. 

(H)    Except as set forth in Section 9.02, the obligations of the Guarantor hereunder shall not
be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guarantee Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any
defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guarantee Obligations or otherwise. Without limiting the generality of the foregoing, the Guarantee
Obligations of the Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company, the Guarantor or any other
person under this Indenture, the Notes or any other agreement or otherwise; (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration or otherwise; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any
other agreement; (d) the release of any security held by any Holder for the Guarantee Obligations; (e) any change in the ownership of the Company; (f) any Default, failure or delay, willful or otherwise, in the performance of the
Guarantee Obligations or (g) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of the Guarantor or would otherwise operate as a discharge of the Guarantor as
a matter of law or equity. 
 (I)    The Guarantor agrees that its Guarantee herein shall remain in full force and
effect until payment in full of all the Guarantee Obligations or the Guarantor is released from its Guarantee in compliance with Section 6.01 or Section 10.01 hereof. The Guarantor further agrees
that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, or interest on any of the Guarantee Obligations is rescinded or must otherwise be restored
by any Holder upon the bankruptcy or reorganization of the Company or otherwise. 

  
 - 74 - 













 (J)    In furtherance of the foregoing and not in limitation of any
other right which any Holder has at law or in equity against the Guarantor by virtue hereof, upon the failure of the Company to pay any of the Guarantee Obligations when and as the same shall become due, whether at maturity, by acceleration, upon a
Fundamental Change Repurchase Date, by Redemption or otherwise, the Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee on behalf of the
Holders an amount equal to the sum of (i) the unpaid amount of such Guarantee Obligations then due and owing and (ii) accrued and unpaid interest on such Guarantee Obligations then due and owing (but only to the extent not prohibited by
law) (including interest accruing after the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the Company or the Guarantor whether or not a claim for postfiling or post-petition
interest is allowed in such proceeding). 
 (K)    The Guarantor further agrees that, as between the Guarantor, on the
one hand, and the Holders, on the other hand, (x) the maturity of the Guarantee Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Guarantee herein, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Guarantee Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of the Guarantee Obligations, the Guarantee Obligations (whether or not due
and payable) shall forthwith become due and payable by the Guarantor for the purposes of this Guarantee. 
 (L)    The
Guarantor also agrees to pay any and all fees, costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee or the Holders in enforcing any rights under this Section 9.01. 

(M)    The Guarantor hereby agrees that to the extent that the Guarantor shall have paid more than its proportionate share
of any payment made on the obligations under the Guarantee, the Guarantor shall be entitled to seek and receive contribution from and against the Company who has not paid its proportionate share of such payment. The provisions of this
Section 9.01(M) shall in no respect limit the obligations and liabilities of the Guarantor to the Trustee and the Holders and the Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed
by the Guarantor hereunder. 
 (N)    Subrogation. Notwithstanding any payment or payments made by the Guarantor
hereunder, the Guarantor shall not be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Company or guarantee or right of offset held by the Trustee or any Holder for the payment of the Guarantee Obligations, nor
shall the Guarantor seek or be entitled to seek any contribution or reimbursement from the Company in respect of payments made by the Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the
Guarantee Obligations are paid in full. If any amount shall be paid to the Guarantor on account of such subrogation rights at any time when all of the Guarantee Obligations shall not have been paid in full, such amount shall be held by the Guarantor
in trust for the Trustee and the Holders, segregated from other funds of the Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned over to the Trustee in the exact form received by the Guarantor (duly indorsed by the Guarantor to
the Trustee, if required), to be applied against the Guarantee Obligations. 

  
 - 75 - 













 Section 9.02.    LIMITATION ON
GUARANTOR LIABILITY. 
 The Guarantor and, by its acceptance of a Note, each Holder of a Note hereby
confirms that it is the intention of all such parties that in no event shall any Guarantee Obligations under the Guarantee constitute or result in a fraudulent transfer or conveyance for purposes of, or result in a violation of, any United States
federal, or applicable United States state, fraudulent transfer or conveyance or similar law. To effectuate the foregoing intention, in the event that the Guarantee Obligations, if any, in respect of the Notes would, but for this sentence,
constitute or result in such a fraudulent transfer or conveyance or violation, then the liability of the applicable Guarantor under its Guarantee in respect of the Notes shall be reduced to the extent necessary to eliminate such fraudulent transfer
or conveyance or violation under the applicable fraudulent transfer or conveyance or similar law. 
 Article 10.
    SATISFACTION AND DISCHARGE 
 Section 10.01.    TERMINATION OF
COMPANY’S OBLIGATIONS. 
 The Indenture and the Guarantee will be discharged, and will
cease to be of further effect, as to all Notes issued under the Indenture, when: 
 (A)    all Notes then outstanding
(other than Notes replaced pursuant to Section 2.12) have (i) been delivered to the Trustee for cancellation; or (ii) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the
Maturity Date, upon conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed; 

(B)    the Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with
respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash (or, with respect to Notes to be converted, Conversion Consideration)
sufficient to satisfy all amounts or other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.12); 

(C)    the Company has paid all other amounts payable by it under the Indenture with respect to the Notes; and 

(D)    the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that
the conditions precedent to the discharge of the Indenture with respect to the Notes have been satisfied; 
 provided, however, that Article
VII of the Base Indenture and Section 11.01 will survive such discharge and, until no Notes remain outstanding, Section 2.14 and the obligations of the Trustee, the Paying Agent and the Conversion
Agent with respect to money or other property deposited with them will survive such discharge. 
 At the Company’s written request, the
Trustee will acknowledge the satisfaction and discharge of the Indenture as to the Notes. 

  
 - 76 - 













 Section 10.02.    REPAYMENT TO
COMPANY. 
 Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will
promptly notify the Company if there exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two
(2) years after the date on which such payment or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion
Consideration or other property, and Holders entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company. 

Section 10.03.    REINSTATEMENT. 

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to
Section 10.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or otherwise prohibits such application, then the discharge of the Indenture
pursuant to Section 10.01 will be rescinded; provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company will be
subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable. 

Article 11.     MISCELLANEOUS 

Section 11.01.    NOTICES.

and delivered in person or by first class mail (registered or certified, return receipt requested), facsimile transmission, electronic transmission or other similar means of unsecured electronic communication or overnight air courier guaranteeing

The Company, the Guarantor or the Trustee, by notice to the others, may designate additional or different addresses (including facsimile
numbers and electronic addresses) for subsequent notices or communications. 
 All notices and communications (other than those sent to
Holders) will be deemed to have been duly given: (A) at the time delivered by hand, if personally delivered; (B) five (5) Business Days after being deposited in the mail, postage prepaid, if mailed; (C) when receipt acknowledged, if

notice or communication to a Holder of a Global Note may, but need not, instead be sent pursuant to the Depositary Procedures (in which case, such notice will be deemed to be duly sent or given in writing). The failure to send a notice or
communication to a Holder, or any defect in such notice or communication, will not affect its sufficiency with respect to any other Holder. 

If the Trustee is then acting as the Depositary’s custodian for the Notes, then, at the reasonable request of the Company to the Trustee,
the Trustee will cause any notice prepared by the Company to be sent to any Holder(s) pursuant to the Depositary Procedures, provided such request is evidenced in a Company Order delivered, together with a copy of such notice to be sent, to
the Trustee at least two (2) Business Days before the date such notice is to be so sent. For the avoidance of doubt, such Company Order need not be accompanied by an Officer’s Certificate or Opinion of Counsel. The Trustee will not have
any liability relating to the contents of any notice that it sends to any Holder pursuant to any such Company Order. 

  
 - 78 - 













 If a notice or communication is mailed or sent in the manner provided above within the time
prescribed, it will be deemed to have been duly given, whether or not the addressee receives it. 
 Notwithstanding anything to the contrary
in the Indenture or the Notes, (A) whenever any provision of the Indenture requires a party to send notice to another party, no such notice need be sent if the sending party and the recipient are the same Person acting in different capacities;
and (B) whenever any provision of the Indenture requires a party to send notice to more than one receiving party, and each receiving party is the same Person acting in different capacities, then only one such notice need be sent to such Person.

 Section 11.02.    DELIVERY OF OFFICER’S
CERTIFICATE AND OPINION OF COUNSEL AS TO CONDITIONS PRECEDENT. 

Upon any request or application by the Company to the Trustee to take any action under the Indenture (provided no Opinion of Counsel need be

Section 11.03 and states that, in the opinion of the signatory thereto, all conditions precedent and covenants, if any, provided for in the Indenture relating to such action have been satisfied; and 

(B)    an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee that complies with
Section 11.03 and states that, in the opinion of such counsel, all such conditions precedent and covenants, if any, have been satisfied.

TRUSTEE, THE REGISTRAR AND THE PAYING AGENT. 

The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set
reasonable requirements for its functions. 
 Section 11.05.    NO PERSONAL
LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS. 

No past, present or future director, officer, employee, incorporator or stockholder of the Company or the Guarantor, as such, will have any
liability for any obligations of the Company or the Guarantor under the Indenture, the Notes or the Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting any Note, each Holder waives
and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes. 

Section 11.06.    GOVERNING LAW; WAIVER OF JURY
TRIAL. 
 THE INDENTURE, THE GUARANTEE AND THE NOTES, AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO
THE INDENTURE, THE GUARANTEE OR THE NOTES, WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EACH OF THE COMPANY, THE GUARANTOR, THE TRUSTEE AND EACH HOLDER (BY ITS ACCEPTANCE OF ANY NOTE) IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE, THE NOTES, THE GUARANTEES OR THE TRANSACTIONS CONTEMPLATED BY THE INDENTURE, THE NOTES OR THE
GUARANTEE.

Any legal suit, action or proceeding arising out of or based upon the Indenture or the transactions contemplated by the Indenture may be
instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York, in each case located in the City of New York (collectively, the “Specified Courts”), and each
party irrevocably submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail (to the extent allowed under any
applicable statute or rule of court) to such party’s address set forth in Section 11.01 will be effective service of process for any such suit, action or proceeding brought in any such court. Each of the Company, the
Guarantor, the Trustee and each Holder (by its acceptance of any Note) irrevocably and unconditionally waives any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally
waives and agrees not to plead or claim any such suit, action or other proceeding has been brought in an inconvenient forum.

 Section 11.08.    NO ADVERSE
INTERPRETATION OF OTHER AGREEMENTS. 
 Neither the Indenture nor the Notes
may be used to interpret any other indenture, note, loan or debt agreement of the Company or its Subsidiaries or of any other Person, and no such indenture, note, loan or debt agreement may be used to interpret the Indenture or the Notes.

All agreements of the Company in the Indenture and the Notes will bind its successors. All agreements of the Trustee in the Indenture will bind
its successors. 
 Section 11.10.    FORCE MAJEURE. 

The Trustee and each Note Agent will not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility
under the Indenture or the Notes by reason of any occurrence beyond its control (including any act or provision of any present or future law or regulation or governmental authority, act of God or war, civil unrest, local or national disturbance or
disaster, act of terrorism or unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility). 

Section 11.11.    U.S.A. PATRIOT ACT. 

The Company acknowledges that, in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee, like all financial institutions, in
order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The Company
agrees to provide the Trustee with such information as it may request to enable the Trustee to comply with the U.S.A. PATRIOT Act. 

Section 11.12.    CALCULATIONS. 

The Company will be responsible for making all calculations called for under the Indenture or the Notes, including determinations of the Last
Reported Sale Price, the Daily Conversion Value, the Daily Cash Amount, the Daily Share Amount, accrued interest on the Notes and the Conversion Rate. 

The Company will make all calculations in good faith, and, absent manifest error, its calculations will be final and binding on all Holders.
The Company will provide a schedule of its calculations to the Trustee, the Conversion Agent and any Holder upon written request therefor, and each of the Trustee and the Conversion Agent may rely conclusively on the accuracy of the Company’s
calculations without independent verification. 
 Section 11.13.    SEVERABILITY; ENTIRE
AGREEMENT. 
 If any provision of the Indenture or the Notes is invalid, illegal or unenforceable, then the validity,
legality and enforceability of the remaining provisions of the Indenture or the Notes will not in any way be affected or impaired thereby. The Base Indenture, this Supplemental Indenture and the exhibits hereto and thereto set forth the entire
agreement and understanding of the parties related to this transaction and supersedes all prior agreements and understandings, oral or written.

The parties may sign any number of copies of the Indenture. Each signed copy will be an original, and all of them together represent the same

paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means, provided that, notwithstanding anything herein to the contrary, the Trustee is not under any
obligation to agree to accept electronic signatures in any form or in any format unless agreed to by it pursuant to reasonable procedures approved by such parties.

meanings ascribed to them in the Indenture. 
 The Indenture sets forth the rights and obligations of the Company, the Guarantor, the
Trustee and the Holders and the terms of the Notes. Notwithstanding anything to the contrary in this Note, to the extent that any provision of this Note conflicts with the provisions of the Indenture, the provisions of the Indenture will control.

in respect of, or by reason of, such obligations or their creation. By accepting any Note, each Holder waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes. 

14.    Authentication. No Note will be valid until it is authenticated by the Trustee. A Note will be deemed to be
duly authenticated only when an authorized signatory of the Trustee (or a duly appointed authenticating agent) manually signs the certificate of authentication of such Note.
