case as applicable, by this First Supplemental Indenture and to the extent expressly permitted hereunder. 
 Section 2.02. Form of
Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby expressly
incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this First Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. 

Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the
provisions of the Indenture as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated
quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the Officer
executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any
particular Notes are subject. 
 Each Global Note shall represent such principal amount of the outstanding Notes as shall be specified
therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be
increased or reduced to reflect repurchases, cancellations, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented
thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with the Indenture. Payment of principal (including the Fundamental Change
Repurchase Price, if applicable) of, and accrued and unpaid interest on, a Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is
provided for herein.

 Section 2.03. Date and Denomination of Notes; Payments of Interest and Defaulted
Amounts. (a) The Notes shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the date of its authentication and shall bear interest from the
date specified on the face of such Note. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial
months, on the basis of the number of days actually elapsed in a 30-day month. 
 (b) The Person in
whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment
Date. The principal amount of any Note (x) in the case of any Physical Note, shall be payable at the office or agency of the Company maintained by the Company for such purposes in the contiguous United States, which shall initially be the
Corporate Trust Office of the Trustee and (y) in the case of any Global Note, shall be payable by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Company shall pay interest (i) on any
Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding
Physical Notes having an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or, upon application by such a Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer in
immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary or (ii) on any Global Note by wire transfer of
immediately available funds to the account of the Depositary or its nominee. 
 (c) Section 2.13 of the Base Indenture shall not apply to
the Notes. Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes plus one percent, subject to the enforceability thereof under
applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the
Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time
the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts 

  
 13 








 
or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date
of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such special record date and the Trustee, in the name and at the expense of
the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder not less than 10 days prior to such special record date. Notice of the proposed payment of such
Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such
special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(c). 

(ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of
any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the
Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

Section 2.04. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The last sentence of
the first paragraph of Section 2.07 of the Base Indenture and the second paragraph of Section 2.07 of the Base Indenture shall not apply to the Notes. 

(b) No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or
the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the
name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer. 

Notwithstanding anything to the contrary in the Indenture, none of the Company, the Trustee, the Registrar or any co-Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for
conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not validly withdrawn) in accordance with Article 12. 

(c) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the third
paragraph of Section 2.04(d) all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of
beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture and the procedures of the Depositary
therefor. 

  
 14 








 (d) Notwithstanding any other provisions of the Indenture (other than the provisions set forth in
this Section 2.04(d)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding
paragraph. 
 The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially,
each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. 

Section 2.14(b) of the Base Indenture shall not apply to the Notes. If (i) the Depositary notifies the Company at any time that the
Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor
depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests through the Depositary that its beneficial interest therein be issued
as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a
Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each
beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee
such Global Notes shall be canceled. 
 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section
2.04(d) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding
paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives 

  
 15 








 
Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures
and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to
reflect such reduction or increase. 
 None of the Company, the Trustee or any agent of the Company or the Trustee shall have any
responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership
interests. 
 (e) Any Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at
any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities
Act in a transaction that results in such Note no longer being a “restricted security” (as defined under Rule 144 as promulgated under the Securities Act). The Company shall cause any Note that is repurchased or owned by it to be
surrendered to the Trustee for cancellation in accordance with Section 2.12 of the Base Indenture (as amended by Section 2.06 of this First Supplemental Indenture). 

Section 2.05. Mutilated, Destroyed, Lost or Stolen Notes. The second sentence of Section 2.08 of the Base Indenture shall not
apply to the Notes. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or the Paying Agent upon the issuance of any substitute Note as provided in Section 2.08
of the Base Indenture, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note
being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted
in accordance with Article 11 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same
(without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or
indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the
Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with
respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with
respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

  
 16 








 Section 2.06. Cancellation of Notes Paid, Converted, Etc. Section 2.12 of the
Base Indenture is hereby amended with respect to the Notes by (i) replacing the first sentence thereof with the sentence: “The Company shall cause all Notes surrendered for the purpose of payment, repurchase, registration of transfer or
exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation” and (ii) inserting at the end of the
fourth sentence thereof the phrase “, except as expressly permitted by any of the provisions of the Indenture”. 

Section 2.07. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding
Section 2.01, reopen the Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, the issue price and interest accrued prior to the issue date of such
additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a
separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to
cover such matters, in addition to those required by Section 11.04 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether
such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements,
including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance
with Section 2.06 and such Notes shall no longer be considered outstanding under the Indenture upon their repurchase.

such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.03: 

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental Change
Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including
the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and 

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the
Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal (including the Fundamental Change
Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid
interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent
by 11:00 a.m., New York City time, on such date. 
 (c) If the Company shall act as its own Paying Agent, it will, on or before each due date
of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such
principal (including the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make

amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with
respect to such sums or amounts. 
 (e) Section 8.06 of the Base Indenture shall not apply to the Notes. All references in the Base Indenture

the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid
interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price, if applicable), interest or consideration due upon conversion has become
due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon
cease. 
 Section 4.04. Reports. (a) The Company shall file with the Trustee, within 15 days after the same are required to
be filed with the SEC, copies of any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule

at the time such documents are filed via the EDGAR system. The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with its covenants under this Section 4.04(a) or with respect to
any reports or other documents filed with the SEC or the SEC’s EDGAR system or any other website. 
 (b) Delivery of the reports and
documents described in subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information
contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). 

Section 4.05. Statements as to Defaults. The Company shall deliver to the Trustee, within 30 days after the occurrence of any

now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated
maturity, upon required repurchase, upon declaration of acceleration or otherwise, and such acceleration or failure to pay is not cured, waived, rescinded, stayed or annulled or such indebtedness is not discharged, as applicable, within a period of

custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days. 

Section 5.03. Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body), then, and in each and every such case (other than an Event of Default specified in Section 5.02(i) or Section 5.02(j) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of the Notes
shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100%
of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in the Indenture
or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 5.02(i) or Section 5.02(j) with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and
accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable. 
 The immediately
preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been
obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due
otherwise than by acceleration (with interest on overdue 

  
 22 








 
installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes plus one
percent at such time) and amounts due to the Trustee pursuant to Section 7.07 of the Base Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (2) any and all existing
Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such declaration of acceleration, shall have been cured or waived pursuant to
Section 5.09 and (3) all sums paid or advanced by the Trustee and the compensation expenses and disbursements of the Trustee and its agents and counsel have been paid, then and in every such case (except as provided in the immediately
succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and
annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; but no such waiver or rescission and annulment shall
extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any
Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when
required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 

Section 5.04. Additional Interest. Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the
Company elects, the sole remedy for an Event of Default relating to (a) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the TIA any documents or reports that the Company is required to file with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act or (b) the Company’s failure to comply with its obligations as set forth in Section 4.04(a) of this First Supplemental Indenture shall after the occurrence of such an Event of
Default consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to (x) 0.25% per annum of the principal amount of the Notes outstanding for each day during the 90-day
period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and ending on, but excluding, the earlier of (A) the date on which such Event of Default is no longer
continuing and (B) the 91st day following the date on which such an Event of Default first occurs, and (y) 0.50% per annum of the principal amount of the Notes outstanding for each day during the 90-day
period on which such Event of Default is continuing beginning on, and including, the 91st day following the date on which such an Event of Default first occurs and ending on, but excluding, the date on which such Event of Default is no longer
continuing. If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st day after such Event of Default (if such Event of Default is not cured
or waived prior to such 181st day), the Notes shall be immediately subject to acceleration as provided in Section 5.03. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any


  
 23 








 
other Event of Default. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 5.04 or the Company elected to make
such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 5.03. 

In order to elect to pay Additional Interest as the sole remedy during the first 180 days after the occurrence of any Event of Default
described in the immediately preceding paragraph, the Company shall notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the
failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 5.03. If Additional Interest is payable on the Notes, the Company shall provide an Officer’s Certificate to the Trustee on or
before the Regular Record Date for each Interest Payment Date such Additional Interest is payable setting forth the accrual period and the amount of such Additional Interest in reasonable detail. The Trustee may provide a copy of such Officer’s
Certificate or other notice received from the Company relating to Additional Interest to any Holder upon request. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume
without inquiry that no such Additional Interest is payable. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether any Additional Interest is payable, or with respect to the nature, extent or
calculation of the amount of any Additional Interest owed, or with respect to the method employed in such calculation of any Additional Interest. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall
deliver to the Trustee an Officer’s Certificate setting forth the particulars of such payment. 
 Section 5.05. Payments of
Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 5.02 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes,
the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes plus one percent at such time, and, in addition thereto, such
further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.07 of the Base Indenture. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of the Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

  
 24 








 Section 5.06. Application of Monies Collected by Trustee. Any monies or property
collected by the Trustee pursuant to this Article 5, or after an Event of Default any money or property distributable with respect to the Notes, shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution
of such monies or property, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

First, to the payment of all amounts due the Trustee under Section 7.07 of the Base Indenture; 

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any
cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon
such overdue payments at the rate borne by the Notes at such time, plus one percent, such payments to be made ratably to the Persons entitled thereto; 

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal
and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the
whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over
interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change
Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder,
if any, to the Company. 
 Section 5.07. Proceedings by Holders. Section 6.06 of the Base Indenture shall not apply to the
Notes. Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no
Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously
shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 
 (b) Holders of
at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

  
 25 








 (c) such Holders shall have offered to the Trustee such security or indemnity reasonably
satisfactory to it against any loss, liability or expense to be incurred therein or thereby; 
 (d) the Trustee for 60 days after its receipt
of such notice, request and offer of such security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 

(e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the
Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 5.09, 

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that
no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and
enforcement of this Section 5.07, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision of the Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as
the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the
respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be
impaired or affected without the consent of such Holder. 
 Section 5.08. Remedies Cumulative and Continuing. Except as provided
in the last paragraph of Section 2.05, all powers and remedies given by this Article 5 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and
remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of
any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence
therein; and, subject to the provisions of Section 5.07, every power and remedy given by this Article 5 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or
by the Holders. 

  
 26 








 Section 5.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders.
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the
payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 5.02, (ii) a failure by the Company to
pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of each Holder of an
outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 5.09, said Default or Event of Default shall for all purposes of the Notes and the Indenture
be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 

Section 5.10. Notice of Defaults. Section 7.05 of the Base Indenture is hereby amended with respect to the Notes by inserting
immediately prior to the words “any Note” in the third line thereof the phrase “, or a Default or Event of Default in respect of the payment or delivery of the consideration due upon conversion in respect of,”. 

Section 5.11. Undertaking to Pay Costs. All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 5.11 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the
principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the
enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 11.

of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in the Indenture or the Notes
following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such
holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of the Indenture. 

Section 7.05. Company-Owned Notes. Notes that are owned as described in Section 2.10 of the Base Indenture that have been
pledged in good faith may be regarded as outstanding for the purposes of such Section 2.10 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is
not the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon
request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons;
and, subject to Section 7.01 of the Base Indenture, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding
for the purpose of any such determination.

 Section 7.06. Revocation of Consents; Future Holders Bound. At any time prior to (but
not after) the evidencing to the Trustee, as provided in Section 7.02, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in the Indenture in connection with such action, any
Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at the Corporate Trust Office of the Trustee and upon proof of holding as
provided in Section 7.03, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note
and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon
registration of transfer thereof.

the Base Indenture, and all references in the Base Indenture to such Sections and amendment and waiver provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to Section 9.02 and Section 9.03,
as applicable, and the supplemental indenture provisions set forth therein. 

  
 32 








 Section 9.02. Supplemental Indentures Without Consent of Holders. The Company and the
Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes: 

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

(b) to provide for the assumption by a Successor Company of the obligations of the Company under the Indenture pursuant to Article 10; 

(c) to add guarantees with respect to the Notes; 

(d) to provide for the issuance of additional Notes; 

(e) to secure the Notes;

 (i) to
comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA; or 
 (j) to conform the
provisions of the Indenture or the Notes to the “Description of Notes” section of the Prospectus Supplement. 
 Upon the written
request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall
not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 9.02 may be executed by the Company and the Trustee without the
consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 9.03. 

Section 9.03. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 7) of the
Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 7 and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange
offer for, Notes), the Company and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the 

  
 33 








 
purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying in any manner the rights of the
Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall: 

(a) reduce the amount of Notes whose Holders must consent to an amendment; 

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

(c) reduce the principal of or extend the Maturity Date of any Note; 

(d) make any change that adversely affects the conversion rights of any Notes;

 (f)
make any Note payable in money, or at a place of payment, other than that stated in the Note; 
 (g) change the ranking of the Notes; or 

(h) make any change in this Article 9 that requires each Holder’s consent or in the waiver provisions in Section 5.03 or
Section 5.09. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as
aforesaid and subject to Section 9.06 of the Base Indenture, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities
under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Holders do not need under this Section 9.03 to approve the particular form of any proposed supplemental indenture. It shall be sufficient
if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all
the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 
 Section 9.04.
Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 9, the Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights,

 ARTICLE 10 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 10.01. Applicability of Article 5 of the Base Indenture. Article 5 of the Base Indenture shall not apply to the Notes.
Instead, the consolidation, merger, sale, conveyance and lease provisions set forth in this Article 10 shall, with respect to the Notes, supersede in their entirety such Article 5 of the Base Indenture, and all references in the Base Indenture to
such Article and the Company successor provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 10 and the consolidation, merger, sale, conveyance and lease provisions set forth in this
Article 10, respectively. 
 Section 10.02. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of
Section 10.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless: 

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the
Company under the Notes and the Indenture; and 
 (b) immediately after giving effect to such transaction, no Default or Event of Default
shall have occurred and be continuing under the Indenture. 
 For purposes of this Section 10.02, the sale, conveyance, transfer or
lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all
of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 10.03. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on
all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the
Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be 

  
 35 








 
substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in
its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and
subject to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by an
Officer of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal
rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation,
merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 10 the Person named as the “Company” in the first paragraph of this First Supplemental Indenture (or any successor that shall
thereafter have become such in the manner prescribed in this Article 10) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of
the Notes and from its obligations under the Indenture and the Notes. 
 In case of any such consolidation, merger, sale, conveyance,
transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 

Section 10.04. Opinion of Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall
be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental
indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 10. 

ARTICLE 11 

CONVERSION OF NOTES 

Section 11.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 11, each Holder
of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions
described in Section 11.01(b), at any time prior to the close of business on the Business Day immediately preceding January 1, 2022 and (ii) regardless of the conditions described in Section 11.01(b), on or after January 1, 2022 and
prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 40.0400 shares of Common Stock (subject to adjustment as provided in this Article 11, the
“Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 11.02, the “Conversion Obligation”). 

  
 36 








 (b) (i) Prior to the close of business on the Business Day immediately preceding January 1,
2022, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading
Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale
Price of the Common Stock on each such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set
forth in this First Supplemental Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the
definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company
has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder provides
the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Conversion Rate
on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as the Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000
principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common
Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as
provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company
fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of
the Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If,
at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion
Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee). 

  
 37 








 (ii) If, prior to the close of business on the Business Day immediately preceding
January 1, 2022, the Company elects to: 
 (A) issue to all or substantially all holders of the Common Stock any rights,
options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last
Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(B) distribute to all or substantially all holders of the Common Stock the Company’s assets, securities or rights to
purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement
for such distribution, 
 then, in either case, the Company shall notify all Holders of the Notes, the Trustee and the Conversion Agent (if other than the
Trustee) at least 60 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, a Holder may surrender all or any portion of its Notes for
conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Company’s
announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time. 

(iii) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the
close of business on the Business Day immediately preceding January 1, 2022, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 12.02, or if the Company is a party to a
consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets that occurs prior to the close of business on the Business Day immediately preceding January 1, 2022, in each case, pursuant to which
the Common Stock would be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 60 Scheduled Trading Days prior to the anticipated
effective date of the transaction or event (or, if later, the earlier of (x) the Business Day after the Company gives notice of such transaction or event and (y) the actual effective date of such transaction or event) until 35 Trading Days
after the actual effective date of such transaction or event or, if such transaction or event also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the
Conversion Agent (if other than the Trustee) (x) as promptly as practicable following the date the Company publicly announces such transaction or event but in no event less than 60 Scheduled Trading Days prior to the anticipated effective date
of such 

  
 38 








 
transaction or event or (y) if the Company does not have knowledge of such transaction or event at least 60 Scheduled Trading Days prior to the anticipated effective date of such transaction
or event, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction or event, but in no event later than the actual effective date of such transaction or event. 

(iv) Prior to the close of business on the Business Day immediately preceding January 1, 2022, a Holder may surrender all
or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on March 31, 2017 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for
at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each
applicable Trading Day. If the sale price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). 

Section 11.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Subject to this Section 11.02, Section 11.03(b) and Section 11.07(a), upon conversion of any Note, the Company shall pay or deliver,
as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any
fractional share of Common Stock in accordance with subsection (j) of this Section 11.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering
any fractional share of Common Stock in accordance with subsection (j) of this Section 11.02 (“Combination Settlement”), at its election, as set forth in this Section 11.02. 

(i) All conversions for which the relevant Conversion Date occurs on or after January 1, 2022 shall be settled using the
same Settlement Method. 
 (ii) Except for any conversions for which the relevant Conversion Date occurs on or after
January 1, 2022, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different
Conversion Dates. 
 (iii) If, in respect of any Conversion Date (or the period described in the third immediately succeeding
set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company,
through the Trustee, shall deliver such Settlement Notice to converting Holders no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant
Conversion Date occurs on or after 

  
 39 








 
January 1, 2022, no later than January 1, 2022). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company
shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal
amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per
$1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such
Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. 
 (iv) The
cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the
Company shall deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date; 

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company
shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 50 consecutive Trading Days during the related Observation
Period; and 
 (C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of
such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of
the 50 consecutive Trading Days during the related Observation Period. 
 (v) The Daily Settlement Amounts (if applicable)
and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the
case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion
Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

  
 40 








 (b) Subject to Section 11.02(e), before any Holder of a Note shall be entitled to convert a Note
as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such
Holder is not entitled as set forth in Section 11.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a
facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the
certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate
endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date
to which such Holder is not entitled as set forth in Section 11.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 11 on the Conversion Date for such conversion. No Notice
of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change
Repurchase Notice in accordance with Section 12.03. 
 If more than one Note shall be surrendered for conversion at one time by the
same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 11.03(b) and Section 11.07(a), the Company shall pay or deliver, as the case may be, the consideration due in
respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last Trading Day of the relevant
Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver (if applicable) to the Conversion Agent or to such Holder, or
such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion Obligation. 

  
 41 








 (d) In case any Note shall be surrendered for partial conversion, the Company shall execute and
the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered
Note (or, in the case of a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby), without payment of any service charge
by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in
connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion. 

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to
deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately
preceding sentence. 
 (f) Except as provided in Section 11.04, no adjustment shall be made for dividends on any shares of Common Stock
issued upon the conversion of any Note as provided in this Article 11. 
 (g) Upon the conversion of an interest in a Global Note, the
Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected
through any Conversion Agent other than the Trustee. 
 (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued
and unpaid interest, if any, except as set forth below, and the Company shall not adjust the Conversion Rate to account for any accrued and unpaid interest on the Notes. The Company’s settlement of the full Conversion Obligation shall be deemed
to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but excluding, the relevant
Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of
the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full
amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on
the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for conversions following the Regular
Record Date immediately 

  
 42 








 
preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately
following the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on
the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date in cash regardless of whether their Notes have been converted following such Regular Record Date. 

(i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record as of the
close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related
Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 

(j) The Company shall not issue any fractional shares of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of
delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation
Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares of Common Stock that shall be issued upon conversion thereof shall be computed on
the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional share of Common Stock remaining after such computation shall be paid in cash. 

Section 11.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.
(a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described
below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes
to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the
Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof,
the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). 

  
 43 








 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change
pursuant to Section 11.01(b)(iii), the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 11.02; provided, however,
that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any
conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000
principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business
Day following the Conversion Date. The Company shall notify the Holders of Notes and the Trustee of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days
after such Effective Date. 
 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be
determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be
paid) per share of Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of
Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading
Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate
that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in Section 11.04) or expiration date of the event
occurs during such five consecutive Trading Day period. 
 (d) The Stock Prices set forth in the column headings of the table below shall be
adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which
is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted
in the same manner and at the same time as the Conversion Rate as set forth in Section 11.04. 
 (e) The following table sets forth the
number of Additional Shares by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 11.03 for each Stock Price and Effective Date set forth below:

 The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case: 

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in
the table, the number of Additional Shares by which the Conversion Rate shall be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier
and later Effective Dates, as applicable, based on a 365-day year; 
 (ii) if the
Stock Price is greater than $100.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the
Conversion Rate; and 
 (iii) if the Stock Price is less than $18.50 per share (subject to adjustment in the same manner as
the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 54.0540 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 11.04. 
 (f) Nothing in this Section 11.03 shall prevent
an adjustment to the Conversion Rate pursuant to Section 11.04 in respect of a Make-Whole Fundamental Change. 
 Section 11.04.
Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes
participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any
of the transactions described in this Section 11.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of
Notes held by such Holder. 

  
 45 








 (a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on
shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 
  





 
 where, 
  

	CR0    =	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on
the Effective Date of such share split or share combination, as applicable; 

  

	CR’    =	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date; 


 

	OS0    =	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and 


 

	OS’    =	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination. 


Any adjustment made under this Section 11.04(a) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of
the type described in this Section 11.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company issues to all or
substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase Common Stock at a price per share
that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion
Rate shall be increased based on the following formula: 
  
 



 
 where, 

  
 46 









	CR0    =	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance; 


 

	CR’    =	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date; 


 

	OS0    =	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date; 


 

	X       =	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and 

  

	Y       =	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants. 


Any increase made under this Section 11.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective
immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the
Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock
actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance
had not occurred. 
 For purposes of this Section 11.04(b) and for the purpose of Section 11.01(b)(ii)(A), in determining whether any
rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and
including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company
for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,
options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section
11.04(a) or Section 11.04(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section 11.04(d) shall apply, and (iii) Spin-Offs as to which the provisions set forth below in this Section 11.04(c)
shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate
shall be increased based on the following formula: 

  
 47 








 



 
 where, 
  

	CR0       =	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution; 


 

	CR’      =	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date; 


 

	SP0       =	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and 

  

	FMV    =	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for
such distribution. 

 Any increase made under the portion of this Section 11.04(c) above shall become effective immediately after the open of
business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such
distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing
increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property
such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines
the “FMV” (as defined above) of any distribution for purposes of this Section 11.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same
period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for
such distribution. 
 With respect to an adjustment pursuant to this Section 11.04(c) where there has been a payment of a dividend or other
distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading
on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 

  
 48 








 



 
 where, 
  

	CR0       =	the Conversion Rate in effect immediately prior to the end of the Valuation Period; 

  

	CR’       =	the Conversion Rate in effect immediately after the end of the Valuation Period; 

  

	FMV0    =	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the
definition of Last Reported Sale Price as set forth in Section 1.02 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and 

  

	MP0      =	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period. 

 The increase to
the Conversion Rate under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable,
if the relevant Conversion Date occurs during the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or
Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed replaced with
such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such Trading Day in determining the Conversion Rate as of such
Trading Day. If the Ex-Dividend Date for such Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect
of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph will be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have
elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the last Trading Day of such Observation Period. 

For purposes of this Section 11.04(c) (and subject in all respect to Section 11.11), rights, options or warrants distributed by the
Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the
occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the
Common Stock, shall be deemed not to have been distributed 

  
 49 








 
for purposes of this Section 11.04(c) (and no adjustment to the Conversion Rate under this Section 11.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such
rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 11.04(c). If any such right, option or warrant, including any such
existing rights, options or warrants distributed prior to the date hereof, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other
assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which
case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or
warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 11.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate
shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though
it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants),
made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate
shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes of Section 11.04(a), Section 11.04(b) and
this Section 11.04(c), if any dividend or distribution to which this Section 11.04(c) is applicable also includes one or both of: 
 (A) a
dividend or distribution of shares of Common Stock to which Section 11.04(a) is applicable (the “Clause A Distribution”); or 

(B) a dividend or distribution of rights, options or warrants to which Section 11.04(b) is applicable (the “Clause B
Distribution”), 
 then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 11.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 11.04(c) with respect to such
Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 11.04(a) and Section
11.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed
to be the Ex-Dividend Date of the Clause C Distribution and (II) 

  
 50 








 
any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 11.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date”
within the meaning of Section 11.04(b). 
 (d) If any cash dividend or distribution is made to all or substantially all holders of the Common
Stock, the Conversion Rate shall be adjusted based on the following formula: 
  
 



 
 where, 
  

	CR0    =	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution; 


 

	CR’    =	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution; 


 

	SP0    =	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and 


 

	C      =	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock. 


Any increase made under this Section 11.04(d) shall become effective immediately after the open of business on the
Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to
make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms
as holders of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such
cash dividend or distribution. 
 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for
the Common Stock (other than an odd lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock
over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based
on the following formula: 

  
 51 








 



 
 where, 
  

	CR0    =	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;


  

	CR’    =	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;


  

	AC    =	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer; 


 

	OS0    =	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or
exchange in such tender or exchange offer); 

  

	OS’    =	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of 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 of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.


 The increase to the Conversion Rate under this Section 11.04(e) shall occur at the close of business on the 10th Trading Day immediately
following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion
Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be
deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for
which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next
succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the


  
 52 








 
expiration date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the date such
tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph
and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer
expires to, and including, the last Trading Day of such Observation Period. 
 (f) Notwithstanding this Section 11.04 or any other
provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such
Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 11.02(i) based on an
adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 11.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in
the related dividend, distribution or other event giving rise to such adjustment. 
 (g) Except as stated herein, the Company shall not
adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable
securities. 
 (h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 11.04, and to
the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at
least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of
the Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or
distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note
a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

(i) Notwithstanding anything to the contrary in this Article 11, the Conversion Rate shall not be adjusted: 

  
 53 








 (i) upon the issuance of any shares of Common Stock pursuant to any present or
future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

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

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued; 

(iv) upon the repurchase of any shares of Common Stock pursuant to an open-market share purchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the kind described in Section 11.04(e) above; 

(v) solely for a change in the par value of the Common Stock; or 

(vi) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 11 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. However,
the Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments (1) when all such deferred adjustments would result in an aggregate change of at least 1% to the Conversion
Rate, (2) upon conversion of any Note (x) if Cash Settlement or Combination Settlement is applicable to such conversion, on each Trading Day in the Observation Period for such conversion and (y) if Physical Settlement is applicable to
such conversion, on the relevant Conversion Date and (3) on each anniversary of the original issue date of the Notes, in each case, without duplication and regardless of whether the aggregate adjustment is less than 1%. 

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if
not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly
after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall deliver such notice of such
adjustment of the Conversion Rate to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

  
 54 








 (l) For purposes of this Section 11.04, the number of shares of Common Stock at any time
outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include
shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

Section 11.05. Adjustments of Prices. Whenever any provision of the Indenture requires the Company to calculate the Last Reported
Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change),
the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the
Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts are to be calculated. 
 Section 11.06. Shares to Be Fully Paid. The Company shall provide, free
from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming delivery of
the maximum number of Additional Shares pursuant to Section 11.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable). 

Section 11.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination), 
 (ii) any consolidation, merger, combination or similar transaction involving the Company, 

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s
Subsidiaries substantially as an entirety or 
 (iv) any statutory share exchange, 

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including
cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert
such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of 

  
 55 








 
shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each
“unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event,
the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 9.02(h) providing for such change in the right to convert each $1,000 principal amount of Notes;
provided, however, that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of
Notes in accordance with Section 11.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 11.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company
would have been required to deliver upon conversion of the Notes in accordance with Section 11.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been
entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of
Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common
Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of
Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 11.03), multiplied by the price paid per share of Common Stock in such
Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The Company shall 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. 
 Such
supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 11. If, in the
case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such
Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider
necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 12. 

  
 56 








 (b) When the Company executes a supplemental indenture pursuant to subsection (a) of this
Section 11.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property
after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such
supplemental indenture to be delivered to each Holder within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

(c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 11.07. None of the
foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 11.01 and Section 11.02
prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to successive Merger
Events. 
 Section 11.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon
conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of
the SEC, secure such registration or approval, as the case may be. 
 (c) The Company further covenants that if at any time the Common Stock
shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon
conversion of the Notes. 
 Section 11.09. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at
any time be under any duty or responsibility to any Holder 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 shall
not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the


  
 57 








 
Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the
Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 11.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such
Section 11.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any
such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the
Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 11.01(b) 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 11.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company
agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 11.01(b). Without limiting the foregoing, the Trustee (including in
its capacities as Conversion Agent, Paying Agent or Registrar) shall have no responsibility to determine the Trading Price, any Settlement Amount, the Conversion Rate or whether any adjustments to the Conversion Rate are required, or whether the
Notes are convertible. 
 Section 11.10. Notice to Holders Prior to Certain Actions. In case of any: 

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 11.04 or
Section 11.11; 
 (b) Merger Event; or 

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its
Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of the Indenture), the Company shall
cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice
stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined
for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, 

  
 58 








 
liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up. 

Section 11.11. Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes, each
share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each
case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the
provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section
11.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 
 ARTICLE 12 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 12.01. Intentionally Omitted.  

Section 12.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any
time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal thereof that is equal to $1,000 or an integral multiple of $1,000,
on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100%
of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date
falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such
Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 12. 

(b) Repurchases of Notes under this Section 12.02 shall be made, at the option of the Holder thereof, upon: 

  
 59 








 (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering
interests in Global Notes, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental
Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Trustee (or, if at any time the Trustee is not serving as the Paying Agent, such corporate office or agency as shall be designated
by the Paying Agent), or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase
Price therefor. 
 The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 

(i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

 (iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and the
Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate
Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change
Repurchase Notice contemplated by this Section 12.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the second Business Day immediately preceding
the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 12.03. 

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of
withdrawal thereof. 
 (c) On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company
shall provide to all Holders of Notes and the Trustee, the Conversion Agent (in the case of a Conversion Agent other than the Trustee) and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental
Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. Simultaneously with providing such notice, the Company shall
publish a notice containing the information set 

  
 60 








 
forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public
medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing
the Fundamental Change; 
 (ii) the date of the Fundamental Change; 

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 12; 

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 

(vii) if applicable, the Conversion Rate and any adjustments to the Conversion Rate; 

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be
converted only if the Holder validly withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and 

(ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 12.02. 
 At the Company’s request together
with an Officer’s Certificate requesting that the Trustee give such notice together with the notice to be given at least ten Business Days prior to the date the notice is to be sent (unless a shorter period shall be satisfactory to the
Trustee), the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying 

  
 61 








 
Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by
the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled,
and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 

Section 12.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be
withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Trustee (or, if at any time the Trustee is not serving as the Paying Agent, such corporate office or agency as shall be
designated by the Paying Agent) in accordance with this Section 12.03 at any time prior to the close of business on the second Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is
being submitted, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original Fundamental
Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that
if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 
 Section 12.04. Deposit of
Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in
Section 4.03) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price.
Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not validly withdrawn prior to the close of business on the second Business Day immediately
preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions in Section 12.02) and (ii) the time of book-entry
transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 12.02 by mailing checks for the amount payable to the Holders of such Notes entitled
thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall,
promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 

  
 62 








 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee
(or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have been
properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the
Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price and, if applicable, accrued and unpaid
interest). 
 (c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 12.02, the Company shall execute and
the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered (or, in the case of a Global Note, the Trustee, or the Custodian at the
direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby). 

Section 12.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the
Company will, if required: 
 (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 
 (b) file a Schedule TO or any other
required schedule under the Exchange Act; and 
 (c) otherwise comply with all federal and state securities laws in connection with any offer
by the Company to repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 12 to be exercised in the time and in
the manner specified in this Article 12. 
 ARTICLE 13 

No REDEMPTION 

Section 13.01. No Redemption. Article 3 of the Base Indenture shall not apply to the Notes. The Notes shall not be redeemable by
the Company prior to the Maturity Date, and no sinking fund is provided for the Notes.

 [FORM OF REVERSE OF NOTE] 

Horizon Global Corporation 
 2.75%
Convertible Senior Note due 2022 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.75% Convertible
Senior Notes due 2022 (the “Notes”), limited to the aggregate principal amount of $125,000,000 all issued or to be issued under and pursuant to the First Supplemental Indenture dated as of February 1, 2017 (the “First
Supplemental Indenture”), between the Company and Wells Fargo Bank, National Association (the “Trustee”), which amends and supplements the Indenture dated as of February 1, 2017 between the Company and the Trustee (the
“Base Indenture” and, as amended and supplemented by the First Supplemental Indenture and from time to time with respect to the Notes, the “Indenture”) to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate
principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture. 

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by
either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set
forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in
respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect
of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 

  
 A-5 








 No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the
consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as the case may be, herein prescribed. 

The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the
office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations,
without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new
Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 
 The
Notes are not subject to redemption through the operation of any sinking fund or otherwise. 
 Upon the occurrence of a Fundamental Change,
the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change
Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder
hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to
convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted
from time to time as provided in the Indenture.
