number. The restrictive legend set forth above and affixed on any Note will be deemed, in accordance with the terms of the certificate representing such Note, to be removed therefrom upon the Company’s delivery to the Trustee of written notice
to such effect, without further action by the Company, the Trustee, the Holder(s) thereof or any other Person; at such time, such Note will be deemed to be assigned an unrestricted CUSIP number as provided in the certificate representing such Note,
it being understood that the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such Depositary. Without limiting the
generality of any other provision of this Indenture, the Trustee will be entitled to receive an instruction letter from the Company before taking any action with respect to effecting any such mandatory exchange or other process. The Company and the
Trustee reserve the right to require the delivery of such legal opinions, certifications or other evidence as may reasonably be required in order to determine that any proposed transfer of any Note is being made in compliance with the Securities Act
and applicable state securities laws. 
 The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note
as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall
not bear the restrictive legend specified in this Section 2.05(c) and shall not be assigned (or deemed assigned) a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale Restriction Termination Date
and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. 

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), 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 transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner)
by written notice given to the Trustee by or on behalf of the Depositary in accordance with Applicable Procedures and in compliance with this Section 2.05(c). 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as the “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. 

  
 19 

 If: 

(x)    the Depositary (i) 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 or (ii) ceases to be a clearing agency registered under the Exchange Act and in either event the Company fails to appoint a successor depositary within
90 days; or 
 (y)    there has occurred and is continuing an Event of Default and the Depositary notifies the Trustee
of its decision to exchange the Global Note for Certificated Notes, 
 the Company shall execute, and the Trustee, upon receipt of an Officer’s
Certificate, an Opinion of Counsel and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver Certificated 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. 

Certificated Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) 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, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Certificated Notes
to the Persons in whose names such Certificated Notes are so registered. 
 At such time as all interests in a Global Note have been
converted, canceled, redeemed, purchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with Applicable 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 Certificated Notes, converted, canceled, redeemed, purchased or transferred to a transferee who receives Certificated Notes therefor or any Certificated Note is
exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the Applicable 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. 

Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability to any beneficial
owner of a Global Note, member of, or participant in, the Depositary or other Person 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. Neither the Company nor the Trustee shall have any responsibility or liability for any act or omission of the Depositary. All notices and communications to be given to the Holders and all
payments to be made to Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered Holders (which shall be the Depositary or its nominee in the case of a Global Note).

  
 20 

 
The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall
be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. 

(d)    Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon
conversion of a Note shall bear a legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that
continues to be effective at the time of such transfer or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee and any transfer agent for the Common Stock): 

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY
NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 

(1)    REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL
BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 

(2)    AGREES FOR THE BENEFIT OF CARBONITE, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL,
PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE NOTE UPON THE CONVERSION OF WHICH THIS SECURITY WAS DELIVERED OR SUCH
SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW EXCEPT: 

(A)    TO THE COMPANY OR ANY SUBSIDIARY THEREOF; 

(B)    PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS EFFECTIVE UNDER THE SECURITIES
ACT AT THE TIME OF SUCH TRANSFER; 
 (C)    TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT; OR 
 (D)    PURSUANT TO AN
EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

  
 21 

 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE,
THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 

(e)    Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms
may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate
number of shares of Common Stock, which shall not bear the restrictive legend required by Section 2.05(d). 
 (f)    Any
Note that is repurchased or owned by an 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 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 under the Securities Act). The Trustee
shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any
transfers between or among members of, or participants in, the Depositary or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and
to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

(g)    Neither the Trustee nor any agent of the Trustee shall have any responsibility for any actions taken or not taken
by the Depositary. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed,
lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 

  
 22 

 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver
the same upon the receipt of such security and/or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the
Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note 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 14 or redeemed in accordance with Article 16 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 and/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. 
 Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact
that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be
subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute
existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 

Section 2.07. Temporary Notes. Pending the preparation of Certificated Notes, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the
form of the Certificated Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the
Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Certificated Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such
authenticating agent Certificated Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant

  
 23 

 
to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Certificated Notes.
Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as
Certificated Notes authenticated and delivered hereunder. 
 Section 2.08. Cancellation of Notes Paid, Converted, Etc. The Company shall
cause all Notes surrendered for the purpose of payment, repurchase (but excluding Notes repurchased pursuant to cash-settled swaps or other derivatives), redemption, registration of transfer or conversion, if surrendered to any Person other than the
Trustee (including any of the Company’s agents or Subsidiaries), to be surrendered to the Trustee for cancellation, and such Notes shall no longer be considered outstanding for purposes of this Indenture upon their payment, repurchase,
redemption, registration of transfer or conversion. All Notes delivered to the Trustee shall be canceled promptly by it. No Notes shall be authenticated in exchange for any Notes cancelled, except as expressly permitted by any of the provisions of
this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company
Order. If the Company or any of its Subsidiaries shall acquire any of the Notes, such acquisition shall not operate as a purchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee
for cancellation. 
 Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then
generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the
“CUSIP” numbers. 
 Section 2.10. Additional Notes; Purchases. (a) The Company may, from time to time, without the
consent of, or notice to, the Holders, issue additional Notes under this Indenture with the same terms and with the same CUSIP number as the Notes issued on the Issue Date (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 issued on the Issue Date for U.S. federal income tax or
securities law purposes, such additional Notes shall have a separate CUSIP number. Such Notes issued on the Issue Date and the additional Notes shall rank equally and ratably and shall be treated as a single series for all purposes under this
Indenture. 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 17.06, as the Trustee shall reasonably request. 
 (b)    The
Company may, to the extent permitted by law and without the consent of Holders, 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

  
 24 

 
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 (but excluding Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08, and they will no longer be considered outstanding
under this Indenture upon this repurchase. 
 Section 2.11. Ranking. The Notes constitute a senior general unsecured obligation of
the Company, ranking equally in right of payment with all existing and future unsubordinated indebtedness of the Company and ranking senior in right of payment to all existing and future indebtedness of the Company that is expressly made subordinate
to the Notes by the terms of such indebtedness. 
 ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture and the Notes shall upon request of the Company contained in an
Officer’s Certificate cease to be of further effect (except as set forth in the last paragraph of this Section 3.01), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge
of this Indenture and the Notes, when: 
 (i)    either: 

(A)    all Notes theretofore authenticated and delivered (other than (x) Notes which have been
destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust with the Trustee or segregated and held in trust by the Company and
thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or 

(B)    the Company has deposited with the Paying Agent or delivered to Holders, as applicable, after all of
the outstanding Notes have (i) become due and payable, whether at the Maturity Date, any Redemption Date or any Fundamental Change Repurchase Date, and/or (ii) have been converted (and the related Settlement Amounts have been determined),
cash or cash and/or shares of Common Stock (solely to satisfy the Company’s Conversion Obligations), as applicable, sufficient to pay all of the outstanding Notes and/or satisfy all conversions, as the case may be, and pay all other sums due
and payable under this Indenture by the Company; and 
 (ii)    the Company has delivered to the Trustee
an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 

  
 25 

 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee
under Section 7.06 and, if cash or shares of Common Stock shall have been deposited with the Paying Agent pursuant to Section 3.01(i)(B), Section 4.04 shall survive such satisfaction and discharge. 

ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01. Payment of Principal and Interest. The Company shall pay or cause to be paid the principal (including the Fundamental
Change Repurchase Price and Redemption Price, if applicable) of, the Settlement Amounts owed on conversion, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, Settlement Amounts and interest shall be
considered paid on the date due if the Paying Agent, if other than the Company, holds as of 11:00 a.m., New York City time, on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all
principal, Settlement Amounts and interest then due; provided, however, that to the extent any such deposit is received by the Trustee (or applicable Paying Agent) after 11:00 a.m., New York City time on any such due date, such deposit
will be deemed deposited on the next Business Day. Unless such Paying Agent is the Trustee, the Company will promptly notify the Trustee in writing of any failure to take such action. 

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal (including
the Fundamental Change Repurchase Price and Redemption Price, if applicable) and overdue Settlement Amounts owed on conversion to the extent they include cash, at the rate equal to the interest rate on the Notes to the extent lawful; it shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at the same rate to the extent lawful. 

Section 4.02. Maintenance of Office or Agency. The Company shall maintain an office or agency (which may be an office of the Trustee
or an Affiliate of the Trustee) where Notes may be presented or surrendered for registration of transfer or exchange or for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the
Trustee. 
 The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

  
 26 

 The Company hereby appoints the Trustee as Paying Agent, Note Registrar, Custodian and Conversion
Agent and designates the Corporate Trust Office of the Trustee as one such office or agency of the Company. In acting hereunder and in connection with the Notes, the Paying Agent, Note Registrar, Custodian and Conversion Agent shall act solely as an
agent of the Company, and will not thereby assume any obligation towards or relationship of agency or trust for or with any Holder. 

Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a
vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the
Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

(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 and the Redemption Price, if applicable) of, the Settlement Amounts owed on conversion to the extent they include cash, 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 written notice of any failure by the Company to
make any payment of the principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, the Settlement Amounts owed on conversion to the extent they include cash, 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. 

(b)    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 and Redemption Price, if applicable) of, the Settlement Amounts owed on conversion to the extent they include cash, 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 and the Redemption 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 any payment of the principal (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) of, the Settlement Amounts owed
on conversion to the extent they include cash, or accrued and unpaid interest on, the Notes when the same shall become due and payable. 

(c)    Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose
of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this
Section 4.04, such 

  
 27 

 
sums or 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. 
 (d)    Subject to any
applicable escheat laws, any money deposited with 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 and the Redemption Price, if applicable) of,
the Settlement Amounts owed on conversion to the extent they include cash, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price and Redemption
Price, if applicable), the Settlement Amounts owed on conversion to the extent they include cash, or interest 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 all liability of the Company as trustee thereof, shall thereupon cease. 
 Section 4.05. [Reserved].

 Section 4.06. Rule 144A Information Requirement; Reporting; and Additional Interest. (a) For as long as any Notes are
outstanding hereunder, at any time the Company is not subject to Sections 13 and 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issued upon conversion of the Notes shall, at such time,
constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon written request, provide to any Holder, beneficial owner or prospective purchaser of such
Notes or any shares of Common Stock issued upon conversion of the Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or such Common Stock, as the case may be,
pursuant to Rule 144A under the Securities Act. 
 (b)    The Company shall file with the Trustee within 15 days after
the same are required to be filed with the Commission (after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any successor rule under the Exchange Act), copies of any
documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act. Notwithstanding the foregoing, the Company shall in no event be required to file with, or otherwise provide or
disclose to, the Trustee or any Holder any information for which the Company is requesting (assuming such request has not been denied), or has received, confidential treatment from the Commission. Any such document or report that the Company files
with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be filed with the Trustee and the Holders for purposes of this Section 4.06(b) as of the time such documents are filed via the EDGAR system (or
such successor). 
 (c)    Delivery of the reports, information and documents described in Section 4.06(b) to the
Trustee is for informational purposes only, and the Trustee’s receipt of such shall not 

  
 28 

 
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). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with the covenants or with
respect to any reports or other documents filed with the Commission or the Commission’s EDGAR system or any website under this Indenture or participate in any conference calls. 

(d)    Subject to Section 4.06(f) and Section 6.03(b), if, at any time during the
six-month period beginning on, and including, the date that is six months after the Issue Date, the Company fails to timely file any document or report that it is required to file with the Commission pursuant
to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or the Notes are not otherwise freely
tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities
laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes outstanding at a rate of 0.50% per annum of the principal amount of the Notes outstanding
for each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise freely tradable during such period by Holders other than the Company’s Affiliates (or Holders that have
been the Company’s Affiliates at any time during the three immediately preceding months) without restrictions pursuant to Rule 144. 

(e)    Subject to Section 4.06(f) and Section 6.03(b), if, and for so long as, the restrictive legend on the Notes
specified in Section 2.05(c) has not been removed (or deemed removed pursuant to this Indenture and the certificate representing the Note), the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable pursuant
to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding without restrictions pursuant to U.S. securities law or the terms of this
Indenture or the Notes as of the 365th day after the Issue Date, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the restrictive legend on the Notes
has been removed (or deemed removed pursuant to this Indenture and the certificate representing such Note), the Notes are assigned an unrestricted CUSIP and the Notes are freely tradable by such Holders. The restrictive legend on the Notes shall be
deemed removed pursuant to the terms of this Indenture as provided in Section 2.05(c), and, at such time, the Notes will, pursuant to, and subject to the provisions of, such Section, be deemed assigned an unrestricted CUSIP number. However, for the
avoidance of doubt, Global Notes will continue to bear Additional Interest pursuant to this paragraph until such time as they are identified by an unrestricted CUSIP in the facilities of the Depositary therefor, as a result of completion of such
Depositary’s mandatory exchange process or otherwise. 
 (f)    Additional Interest will be payable in arrears on
each Interest Payment Date following accrual in the same manner as regular interest on the Notes and shall be in addition to any Additional Interest that may accrue, at the Company’s election, as the sole remedy relating

to the failure to comply with the Company’s obligations under Section 4.06(b). In no event, however, will Additional Interest accrue on any day (taking into consideration any Additional
Interest payable as described in Section 4.06(d), Section 4.06(e) or Section 6.03(a)) at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

(g)    If Additional Interest is payable by the Company pursuant to Section 4.06(d), Section 4.06(e) or Section 6.03(a),
the Company shall deliver to the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a
Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. 

Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. 

Section 4.08. Compliance Certificate; Statements as to Defaults. 

(a)    The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year (beginning with the year
ended December 31, 2017), an Officer’s Certificate stating whether the signers thereof have knowledge of any Default that occurred during the previous year. Delivery of such reports and documents to the Trustee is for informational
purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein 

(b)    The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee an Officer’s
Certificate within 30 days after an Officer of the Company becomes aware of any event that would constitute a Default or Event of Default, the status and what action the Company is taking or proposes to take with respect thereto.

every such case (other than an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company), either the Trustee by notice in writing to the Company, or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the Notes to be due and
payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable. If an Event of Default specified in Section 6.01(h) or Section 6.01(i) with respect to the Company 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. 

Section 6.03. Additional Interest. 

(a)    Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the
sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall, after the occurrence 

  
 32 

 
of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes (subject to Section 4.06(f) and Section 6.03(b)) at a rate equal to: 

(i)    0.25% per annum of the principal amount of the Notes outstanding for each day during the period
beginning on, and including, the date on which such Event of Default first occurred and ending on the earlier of (x) the date on which such Event of Default is cured or validly waived and (y) the 90th day immediately following, and
including, the date on which such Event of Default first occurred and 
 (ii)    if such Event of Default
has not been cured or validly waived prior to the 91st day immediately following, and including, the date on which such Event of Default first occurred, 0.50% per annum of the principal amount of the Notes outstanding for each day during the period
beginning on, and including, the 91st day immediately following, and including, the date on which such Event of Default first occurred and ending on the earlier of (x) the date on which such Event of Default is cured or validly waived and
(y) the 180th day immediately following, and including, the date on which such Event of Default first occurred. 

(b)    Any Additional Interest payable pursuant to Section 6.03(a) above shall be in addition to any Additional Interest
that may accrue pursuant to Sections 4.06(d) and 4.06(e). Notwithstanding anything in this Indenture to the contrary, in no event, however, shall Additional Interest accrue on any day (taking into consideration any Additional Interest payable
pursuant to Section 6.03(a) above, together with Additional Interest payable pursuant to Sections 4.06(d) and 4.06(e)) at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay
such Additional Interest. 
 (c)    If the Company so elects, the Additional Interest payable pursuant to Section
6.03(a) above shall be payable in the same manner and on the same dates as the stated interest payable on the Notes and will accrue on all Notes then outstanding from, and including, the date on which the Event of Default relating to the
Company’s failure to comply with its obligations as set forth in Section 4.06(b) first occurs to, but not including, the 181st day thereafter (or such earlier date on which such Event of Default is cured or validly waived by the Holders of a
majority in principal amount of the Notes then outstanding). On the 181st day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) is not cured or
validly waived prior to such 181st day), such Additional Interest will cease to accrue and the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest following an
Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) in accordance with this Section 6.03, or the Company elects to make such payment but does not pay the Additional Interest
when due, the Notes shall immediately be subject to acceleration as provided in Section 6.02. For the avoidance of doubt, the provisions of this Section 6.03 shall not affect the rights of Holders in the event of the occurrence of any
other Event of Default. 
 (d)    In order to elect to pay Additional Interest as the sole remedy during the first 180
days after the occurrence of an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b), the Company must notify in writing all 

  
 33 

 
Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) of such election on or before the close of business on the date on which such Event of Default first occurs.
Upon the Company’s failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. The Company may elect to pay Additional Interest with respect to multiple Events of Default in a
single written notification. 
 Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in
clause (a), (b) or (c) of Section 6.01 shall have occurred and the Notes have become due and payable pursuant to Section 6.02, 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 (including the Fundamental Change Repurchase Price and Redemption Price, if applicable), satisfaction of the Conversion Obligation with respect to all Notes that have been
converted, and interest, if any, with (to the extent that payment of such interest shall be legally enforceable) interest on any such overdue amounts, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as
shall be sufficient to cover any amounts due to the Trustee under Section 7.06. 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 monies 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 the
event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company under Bankruptcy Law, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken possession of the Company, the property of the Company, or in the event of any other judicial proceedings relative to the Company, or to the creditors or property of the
Company, the Trustee, irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim
or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it
may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceedings relative to the Company, its creditors, or its property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee
under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses,
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees,
and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, 

  
 34 

 
advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the
possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery
of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this 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. 

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or
abandoned because of any waiver, rescission or a annulment pursuant to Section 6.09 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall,
subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding
had been instituted. 
 Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to
this Article 6 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, 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 7.06; 
 SECOND:    to the payment of the amounts then due and unpaid for principal of, the
Fundamental Change Repurchase Price (if applicable) of, the Redemption Price (if applicable) of, and/or satisfaction of the Conversion Obligation with respect to all Notes that have been converted, and interest on the Notes in respect of which or
for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes; and 

  
 35 

 THIRD:    to the Company. 

Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the
Fundamental Change Repurchase Price and the Redemption Price) or interest when due, or the right to receive payment and/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 this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture or the Notes, or for the appointment of a receiver, trustee, liquidator, custodian or other similar
official, or for any other remedy hereunder, unless: 
 (a)    such Holder has previously given the Trustee written
notice that an Event of Default is continuing; 
 (b)    the Holders of at least 25% in principal amount of the then
outstanding Notes have requested the Trustee in writing to pursue the remedy; 
 (c)    such Holders have offered the
Trustee security and/or indemnity satisfactory to the Trustee against any loss, liability or expense; 
 (d)    the
Trustee has not complied with such request within 60 days after the receipt thereof and the offer of such security or indemnity; and 

(e)    the Holders of a majority in principal amount of the then outstanding Notes have not given the Trustee a direction
that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder, it
being understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial to other Holders. 

Notwithstanding any other provision of this Indenture and any provision of any Note, (i) the contractual right of any Holder to receive
payment or delivery, as the case may be, of (x) principal (including the Fundamental Change Repurchase Price and Redemption Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) consideration due upon
conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, and (ii) the contractual right of any Holder to institute suit for the enforcement of any such payment or delivery, as
the case may be, on or after such respective dates, shall, in each case, not be amended without the consent of such Holder. 
 Section 6.07.
Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and
enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any
power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

  
 36 

 Section 6.08. Remedies Cumulative and Continuing. Except as provided in the last paragraph of
Section 2.06, all powers and remedies given by this Article 6 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 this Indenture, and no delay or omission of the Trustee or of any Holder of any of the
Notes to exercise any right or power accruing upon any Default or Event of Default 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 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders. 

Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. 

(a)    The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding shall have the
right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided, however, that (i) such
direction shall not be in conflict with any rule of law or with this Indenture, and (ii) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any
direction that conflicts with any rule of law or with this Indenture, it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Trustee will be under no obligation to exercise
any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity and/or security satisfactory to it against any loss, liability or expense that might be
incurred by it in compliance with such request or direction. 
 (b)    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 rescind any acceleration with respect to the Notes and its consequences hereunder except: 

(i)    a default in the payment of the principal (including any Fundamental Change Repurchase Price or
Redemption Price, if applicable) of, or accrued and unpaid interest, if any, on the Notes; or 
 (ii)    
a failure by the Company to deliver the consideration due upon conversion of the Notes; 
 provided that, in the case of the rescission of any
acceleration with respect to the Notes, (1) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default (other than the nonpayment of the principal of and
interest on the Notes that have become due solely by such declaration of acceleration) have been cured or waived. 

  
 37 

 Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09,
said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right
consequent thereon. 
 Section 6.10. Notice of Defaults. If a Default occurs and is continuing and is known to a Responsible
Officer of the Trustee, the Trustee shall send to all Holders as the names and addresses of such Holders appear upon the Note Register notice of such Default within 90 days after it occurs. Except in the case of a Default in the payment of principal
of (including the Fundamental Change Repurchase Price and Redemption Price, if applicable) or accrued and unpaid interest, if any, on any Note or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be
protected in withholding such notice if and so long as a committee of trust officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 6.11. Undertaking to Pay Costs. All parties to this 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 this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (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 (including, but not limited to, the Fundamental Change Repurchase Price with respect to the Notes being purchased as provided in this Indenture and Redemption Price, if applicable) or accrued and unpaid interest, if any, on any Note on
or after the due date expressed or provided for in such Note or to any suit for the enforcement of the payment or delivery of consideration due upon conversion.

Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event of Default shall have been given to a
Responsible Officer of the Trustee by the Company or by any Holder of the Notes at the Corporate Trust Office of the Trustee and such notice references the Company, the Notes and this Indenture;

co-Note Registrar with respect to the Notes; 
 (l)    if any party fails to
deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred,
unless such Responsible Officer of the Trustee had actual knowledge of such event; 
 (m)    in the absence of written
investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or
for investment losses, fees, taxes or other charges incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity
date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction
from the Company;

satisfactory to the Trustee against any loss, liability and expense which might be incurred by it in compliance with such request or direction; and 

(p)    the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and

 Section 7.03.
No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any

 41 

 Section 7.04. Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own
Notes. The Trustee, any Paying Agent, any Conversion Agent, the Custodian, Bid Solicitation Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were
not the Trustee, Paying Agent, Conversion Agent, Custodian, Bid Solicitation Agent or Note Registrar. 
 Section 7.05. Monies and
Shares of Common Stock to Be Held in Trust. All monies and shares of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common
Stock held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law or as expressly provided herein. The Trustee shall be under no liability for interest on any money or shares of Common Stock
received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 
 Section 7.06. Compensation and
Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity hereunder (including the reasonable compensation and the expenses and disbursements of its agents and
counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been caused by its negligence or willful misconduct. The Company also covenants to provide indemnification reasonably satisfactory
to the Trustee (which for purposes of this Section 7.06 shall include its officers, directors, employees and agents) in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents
and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without negligence or willful misconduct on the part of the Trustee, its officers, directors, agents or employees, or such
agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this Indenture or in any other capacity hereunder, including the costs and expenses of defending themselves against any
claim (whether asserted by the Company, a Holder or any other Person) of liability in the premises (including, without limitation, any and all reasonable attorneys’ fees and expenses). The obligations of the Company under this Section 7.06
to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the
Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall not be
subordinate to any other liability or indebtedness of the Company and to secure the Company’s payment obligations of the Company in this Section 7.06, the Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee, in its capacity as 

  
 42 

 
the Trustee, other than money or property held in trust to pay principal of and interest, if any, on particular Notes. The obligation of the Company under this Section 7.06 shall survive the
satisfaction and discharge of this Indenture, final payment of the Notes and the earlier resignation or removal of the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.
The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee and to any successor Trustee hereunder. 

Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating
agent incur expenses or render services after an Event of Default specified in Section 6.01(h) or Section 6.01(i) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws. 
 Section 7.07. Officer’s Certificate as Evidence. Except as otherwise provided in
Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate delivered to the
Trustee, and such Officer’s Certificate, in the absence of negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the
faith thereof. 
 Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person
that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section 7.08, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article 7. 
 Section 7.09. Resignation or Removal of Trustee. The Trustee may at any time resign by giving
written notice of such resignation to the Company and by mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor
trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, at the expense of the Company, upon ten Business Days’ notice to the Company and the Holders,
petition any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of
himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

  
 43 

 (a)    In case at any time any of the following shall occur: 

(i)    the Trustee shall fail to comply with Section 7.13 within a reasonable time after written
request therefor by the Company or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months; 

(ii)    the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and
shall fail to resign after written request therefor by the Company or by any such Holder, or 

(iii)    the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed
by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 6.11, any Holder who has been a bona fide holder of a
Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 

(b)    The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove
the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto. If no successor trustee shall have been so appointed
and have accepted appointment within 30 days after removal of the Trustee by the Holders, the Trustee may, at the expense of the Company, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent
jurisdiction for the appointment of a successor trustee. 
 (c)    Any resignation or removal of the Trustee and
appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon (i) payment of all fees and expenses owing to the Trustee and (ii) acceptance of appointment by the successor
trustee as provided in Section 7.10. 
 Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as
provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein;

  
 44 

 
but, nevertheless, on the written request of the Company or of the successor trustee, the predecessor trustee shall, upon payment of any amounts then due it pursuant to the provisions of
Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or
property held or collected by such trustee as such pursuant to this Indenture, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor
trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of appointment by a successor trustee as provided in
this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall send or cause to be sent notice of the succession of such trustee hereunder to the Holders at their addresses as
they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 

Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate
trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided
that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08. 

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or
in the name of the successor trustee; and in all such cases such certificates of authentication shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of authentication of the Trustee shall
have; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger,
conversion or consolidation. 

  
 45 

 Section 7.12. Trustee’s Application for Instructions from the Company. Any application by the
Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the
Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any
action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer actually
receives such application, unless any such Officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written
instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 
 Section 7.13.
Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of this Indenture. 
 Section 7.14 Limitation on Trustee’s Liability. Except as
provided in this Article, in accepting the trusts hereby created, the entities acting as Trustee are acting solely as Trustee hereunder and not in their individual capacity and, except as provided in this Article, all Persons having any claim
against the Trustee by reason of the transactions contemplated by this Indenture or any Note shall look only to the Company for payment or satisfaction thereof 

ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the
aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (i) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or (ii) by the record of
the Holders voting in favor thereof at any meeting of Holders duly called and held, or (iii) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the
taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if
one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action.
 Section 8.02.
Proof of Execution by Holders. Subject to the provisions of Section 7.01 and Section 7.02, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable
rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. 

  
 46 

 Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any
Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and
notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.03) accrued
and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary.
All such payments or deliveries so made to any Holder, or upon its order, shall be valid, and, to the extent 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 this 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 this Indenture.

 Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes
have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Affiliate of the Company shall be disregarded (from both the numerator and the denominator) and deemed not to be
outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible
Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 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 or any Affiliate of the Company. 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, 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 8.05. Revocation of Consents; Future Holders Bound. At any
time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this 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 its Corporate Trust Office and upon proof of holding as

  
 47 

 
provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such
Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor 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.

Notes, on or after the respective due dates expressed or provided for in this Indenture or the Notes); or

waiver unless such amendment, supplement or waiver adversely affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into
such amendment, supplement or waiver. 
 Holders do not need under this Section 10.02 to approve the particular form of any proposed
amendment, supplement or waiver of this Indenture. It shall be sufficient if such Holders approve the substance thereof. After any such amendment, supplement or waiver becomes effective, the Company shall send to the Holders a notice briefly

performed by the Company, such Successor Company (if not the Company) shall succeed to, and may exercise every right and power of and be substituted for, the Company, with the same effect as if it had been named herein as the party of the first
part, and the Company shall be discharged from its obligations under the Notes and this Indenture, except in the case of a lease. 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 

  
 51 

 
delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee
shall authenticate and shall deliver, or cause to be authenticated and delivered, any 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 this Indenture as the Notes theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, transfer or disposition (but not in the case of a lease), upon
compliance with this Article 11, the Person named as the “Company” in the first paragraph of this Indenture shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the
Notes. 
 Section 11.02. Opinion of Counsel to Be Given to Trustee. If a supplemental indenture is required in connection with
this Article 11, 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 complies with the provisions of this Article 11. 
 ARTICLE 12 

IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND

 Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal
of or accrued and unpaid interest on, or the payment or delivery of consideration due upon conversion of, any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement
of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or
Subsidiary, as such, past, present or future, of the Company or of any of its successor corporations or other entities, either directly or through the Company or any of its successor corporations or other entities, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the

 CONVERSION OF NOTES 

Section 14.01. Conversion Privilege. 

(a)    Subject to and upon compliance with the provisions of this Article 14, 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 14.01(b), at any time prior to the
close of business on the Business Day immediately preceding January 1, 2022 under the circumstances and during the periods set forth in Section 14.01(b); 

(ii)    on or after January 1, 2022, at any time 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 38.7034 shares of Common Stock (subject to
adjustment as provided in Section 14.04 and, if applicable, Section 14.03, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion
Obligation”). 
 (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 (that is $1,000 principal amount or an integral multiple thereof) for conversion at any time during the five Business Day period after any five consecutive Trading Day
period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with the procedures described below in 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 and the Conversion Rate on each such Trading Day, subject to compliance with the following procedures concerning the
Bid Solicitation Agent’s obligation to make a Trading Price determination. 
 (A)    The Bid
Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of the 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 of at least $1,000,000 in aggregate principal amount of Notes requests in writing that the
Company makes such a determination and provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the
Conversion Rate on such Trading Day. At the time of such request, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the
Trading Price per $1,000 principal amount of the Notes beginning on the Trading Day following the receipt of such evidence 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 on such Trading Day. 

  
 53 

 (B)    If the Trading Price condition has been met, the
Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading Price condition 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 on such Trading Day, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing.

 (C)    If the Company does not, when it is required to, instruct the Bid Solicitation Agent to (or, if
the Company is acting as Bid Solicitation Agent, it does not) obtain bids, or if the Company gives such instruction to the Bid Solicitation Agent and the Bid Solicitation Agent fails to make such determination (or, if the Company is acting as Bid
Solicitation Agent, it fails to make such determination), then, in either case, the Trading Price per $1,000 principal amount of the 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. 
 (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 (other than pursuant to a stockholders rights plan, so long as such rights have not separated from the shares of Common Stock) entitling them, for a period of not more
than 60 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 (other than pursuant to a stockholders rights plan, so long as such rights have not separated from the shares of Common Stock), 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 immediately preceding the date of announcement of 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 40
Scheduled Trading Days prior to the Ex-Dividend Date of such issuance or distribution. Once the Company has given such notice, the Holders may surrender all or any portion of their Notes (that is $1,000 in
principal amount or an integral multiple thereof) 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. 

  
 54 

 A Holder of the Notes may not convert its Notes pursuant to this Section 14.01(b)(ii) if such
Holder otherwise participates in such issuance or distribution (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding Notes, without
having to convert its Notes as if such Holder held a number of shares of Common Stock equal to (x) the applicable Conversion Rate multiplied by (y) the principal amount (expressed in thousands) of Notes held by such Holder. 

(iii)    If, prior to the close of business on the Business Day immediately preceding January 1, 2022:

 (A)    a Fundamental Change occurs; 

(B)    a Make-Whole Fundamental Change occurs; or 

(C)    the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of
all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole (other than with one of the Company’s Wholly Owned Subsidiaries, unless such transaction also constitutes a Fundamental Change or
Make-Whole Fundamental Change), in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, 
 then, in each
case, the Holders may surrender all or any portion of their Notes (that is $1,000 in principal amount or an integral multiple thereof) for conversion at any time from or after the date that such transaction is effective until the earlier of (x) 35
trading days after the date that such transaction is effective or, if such transaction also constitutes a fundamental change, until the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date and
(y) the second Scheduled Trading Day immediately preceding the Maturity Date. 
 The Company shall notify Holders, the Trustee and the
Conversion Agent (if other than the Trustee) as promptly as practicable following the date the Company publicly announces such transaction, but in no event later than the date that any such transaction is effective. 

(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 (that is $1,000 in principal amount or an integral multiple thereof) for conversion during any calendar quarter commencing after the calendar quarter ending on June 30, 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. 

  
 55 

 (v)    If the Company calls any or all of the Notes for
redemption pursuant to Article 16, then a Holder may surrender all or any portion of its Notes for conversion at any time prior to the close of business on the second Scheduled Trading Day prior to the Redemption Date. After that time, the right to
convert on account of the Company’s delivery of the Redemption Notice shall expire, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert all or any portion of its Notes until the close
of business on the Business Day immediately preceding the date on which the Redemption Price has been paid or duly provided for. 

Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

(a)    Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company
shall, at its election, pay or deliver, as the case may be, to the converting Holder, in full satisfaction of its Conversion Obligation, cash (“Cash Settlement”), shares of the Common Stock (“Physical Settlement”)
or a combination of cash and shares of the Common Stock (“Combination Settlement”), as set forth in this Section 14.02. 

(i)    All conversions for which the relevant Conversion Date occurs on or after January 1, 2022 and
all conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice and prior to the Scheduled Trading Day immediately preceding the related Redemption Date shall be settled using the same
Settlement Method (including the same relative proportion of cash and/or shares of the Common Stock). Except for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice, but prior to the
Scheduled Trading Day immediately preceding the related Redemption Date, and any conversions for which the relevant Conversion Date occurs on or after January 1, 2022, the Company shall use the same Settlement Method (including the same
relative proportion of cash and/or shares of the Common Stock) 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. 
 (ii)    If the Company elects a Settlement Method, the Company shall deliver notice to Holders
through the Conversion Agent (if other than the Trustee) of such Settlement Method the Company has selected no later than the close of business on the second Trading Day immediately following the related Conversion Date, or in the case of any
conversions for which the relevant Conversion Date occurs (x) on or after the date of issuance of a Redemption Notice and prior to the Scheduled Trading Day immediately preceding the related Redemption Date, in such Redemption Notice or
(y) on or after January 1, 2022, no later than January 1, 2022. If the Company does not timely elect a Settlement Method, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement with respect to that
Conversion Date 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. If the Company has timely
elected Combination Settlement in respect of any conversion but does not timely notify the converting Holders of the Specified Dollar Amount per $1,000 principal amount of Notes, or the Company is deemed to have elected Combination Settlement, the
Specified Dollar Amount shall be deemed to be $1,000. 

  
 56 

 (iii)    The cash, shares of Common Stock or combination of
cash and shares of Common Stock payable or deliverable by the Company in respect of any conversion of Notes (the “Settlement Amount”) shall be computed by the Company 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 on the Conversion Date (plus cash in lieu of any
fractional share of Common Stock issuable upon conversion); 
 (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 30 consecutive VWAP Trading Days during the related relevant 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 and deliver, as the case may be, to the converting Holder 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 30 consecutive VWAP Trading Days during the related Observation Period (plus cash in lieu of any fractional share of Common Stock issuable upon conversion). 

If more than one Note shall be surrendered for conversion at any 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 hereby) so surrendered. 

(iv)    The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall
be determined by the Company promptly following the last VWAP Trading Day of the related Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and, if applicable,
the amount of cash payable in lieu of 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, if applicable, the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 

(b)    (i) To convert a beneficial interest in a Global Note (which conversion is irrevocable), the holder of such
beneficial interest must: 
 (A)    comply with the Applicable Procedures; 

  
 57 

 (B)    if required, pay funds equal to all documentary, stamp
or similar issue or transfer tax owed as set forth in Section 14.02(d) and Section 14.02(e); and 

(C)    if required, pay funds equal to any interest payable on the next Interest Payment Date to which such
Holder is not entitled as set forth in Section 14.02(g); and 
 (ii)    To convert a Certificated Note,
the Holder must: 
 (A)    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”) and such Note to the Conversion Agent; 

(B)    if required, furnish appropriate endorsements and transfer documents; 

(C)    if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set
forth in Section 14.02(d) and Section 14.02(e); and 
 (D)    if required, pay funds equal to any
interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(g). 
 The Trustee
(and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion or, if notice on such date is not feasible given the nature of the conversion, promptly
thereafter. 
 If a Holder has already delivered a Fundamental Change Repurchase Notice with respect to a Note, such Holder may not
surrender such Note for conversion until such Holder has validly withdrawn such Fundamental Change Repurchase Notice (or, in the case of a Global Note, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with
the terms of Section 15.03. If a Holder has already delivered a Fundamental Change Repurchase Notice, such Holder’s right to withdraw such notice and convert the Notes that are subject to repurchase will terminate at the close of business
on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date. 
 (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 Section 14.02(b) above. 

  
 58 

 Subject to the provisions of Section 14.03(b) and Section 14.07(a), the Company shall pay or
deliver, as the case may be, the Settlement Amount due in respect of the Conversion Obligation on: 

(i)    the third Business Day immediately following the relevant Conversion Date, if the Company elects
Physical Settlement; or 
 (ii)    the third Business Day immediately following the last VWAP Trading Day
of the relevant Observation Period, if the Company elects Cash Settlement or if the Company elects or is deemed to elect Combination Settlement. 

If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to such Holder, or
such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary, as the case may be, for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s
Conversion Obligation. 
 (d)    In case any Certificated Note shall be surrendered for partial conversion, in $1,000
principal amount or an integral multiple thereof, the Company shall execute and upon receipt of a Company Order, the Trustee shall authenticate and deliver to or upon the written order of the Holder so surrendered a new Note or Notes in authorized
denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, 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 issuance of any shares of Common Stock upon conversion of such Note, 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)    Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian of the Global Note at the
direction of the Trustee, shall make a notation in the books and records of the Trustee and Depositary 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. 
 (g)    Upon conversion of a Note, the converting Holder
shall not receive any separate cash payment representing accrued and unpaid interest, if any, except as set forth in the paragraph below. The Company’s payment or delivery, as the case may be, of the Settlement Amount upon conversion of any
Note 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 not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but
not including, the relevant Conversion Date shall be deemed to be paid in full rather than canceled, 

  
 59 

 
extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the cash paid upon
such conversion. 
 Notwithstanding the immediately preceding paragraph, if Notes are converted after the close of business on a Regular
Record Date for the payment of interest, but prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes shall 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 on the corresponding Interest Payment Date (regardless of whether the converting Holder was the Holder of record on the corresponding Regular Record Date); provided that no such
payment need be made: 
 (i)    if the Notes are surrendered for conversion following the Regular Record
Date immediately preceding the Maturity Date; 
 (ii)    if the Company has specified a Redemption Date
that is after a Regular Record Date and on or prior to the second Scheduled Trading Day immediately following the corresponding Interest Payment Date; 

(iii)    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 

(iv)    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, any Redemption Date as described in clause (ii) above and any Fundamental Change Repurchase Date as described in clause (iii) above shall receive and retain the full interest payment due on the Maturity Date or other
applicable Interest Payment Date regardless of whether their Notes have been converted following such Regular Record Date. 

(h)    The Person in whose name any shares of Common Stock delivered upon conversion is registered shall become the holder
of record of such shares as of the close of business on (i) the relevant Conversion Date if the Company elects Physical Settlement or (ii) the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to
elect Combination Settlement. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion; provided that (a) the converting Holder shall have the right to receive the Settlement Amount due
upon conversion and (b) in the case of a conversion between a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the close of business on such Regular Record Date shall have the right to receive the
interest payable on such Interest Payment Date, in accordance with Section 14.02(g). 

  
 60 

 (i)    The Company shall not issue any fractional share of Common Stock upon
conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion in an amount based on (i) the Daily VWAP on the relevant Conversion Date if the Company elects Physical Settlement or
(ii) the Daily VWAP on the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement. For each Note surrendered for conversion, if the Company has elected (or is deemed to elect)
Combination Settlement, the full number of shares 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, if applicable, any fractional share
remaining after such computation shall be paid in cash. 
 Section 14.03. Increase in Conversion Rate Upon Conversion in Connection with a
Make-Whole Fundamental Change or Redemption Notice. (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or the Company gives a Redemption Notice with respect to any or all of the Notes pursuant
to Section 16.02 and, in either case, a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or Redemption Notice, 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 Conversion Date occurs during the period from the Effective Date of the Make-Whole Fundamental Change to the close of business on 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”). A conversion of Notes shall be deemed for these purposes to be “in connection with” a Redemption Notice if the relevant
Conversion Date occurs during the period from the date of the Redemption Notice to (i) the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date or (ii) if the Company fails to pay the Redemption
Price on the Redemption Date, the close of business on the Business Day immediately preceding the date on which the Redemption Price has been duly paid or duly provided for. 

(b)    Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or in connection with a
Redemption Notice, the Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02; provided, however, that, if the
consideration for the Common Stock in any Make-Whole Fundamental Change described in clause (b) of the definition of 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 (i) the Conversion Rate
(including any increase to reflect the Additional Shares as described in this Section 14.03), multiplied by (ii) such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the

  
 61 

 
third Business Day following the Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole
Fundamental Change no later than five Business Days after such Effective Date (the “Make-Whole Fundamental Change Company Notice”). 

(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: (x) the date on which the Make-Whole Fundamental Change occurs or becomes effective, or the date of the Redemption Notice, as the case may be (in each case, the “Effective Date”), and
(y) the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or with respect to the Optional Redemption, as the case may be (the “Stock Price”). If the holders of the Common Stock
receive 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 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the date of the Redemption Notice, as the case
may be. 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 of the event occurs, during such five 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 is otherwise adjusted. The adjusted Stock Prices shall equal (i) the Stock Prices applicable immediately prior to such adjustment, multiplied by (ii) 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 14.04. 
 (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 14.03 for each Stock Price and Effective Date set forth below:

 The exact Stock Price and Effective Date 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 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 $120.00 per share (subject to adjustment in the same manner as
the Stock Prices set forth in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate; and 

(iii)    if the Stock Price is less than $19.50 per share (subject to adjustment in the same manner as the
Stock Prices set forth in the column headings of the table 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 51.2820 shares of Common
Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 14.04. 
 (f)    Nothing
in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of a Make-Whole Fundamental Change. 

Section 14.04. 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 a share split or share combination), 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 14.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to (i) the Conversion
Rate, multiplied by (ii) the principal amount (expressed in thousands) of Notes held by such Holder. 

(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;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or effective date, as applicable;

  
 63 

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

 Any adjustment made under this Section 14.04(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 14.04(a) is declared that results in an adjustment under this Section 14.04(a) but is 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
(other than pursuant to a stockholders rights plan) entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less
than the average of the Last Reported Sale Prices 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, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to (i) the aggregate price payable to exercise such rights, options or warrants, divided by (ii) 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.

  
 64 

 Any increase made under this Section 14.04(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 14.04(b) and Section
14.01(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 over the 10
consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of 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 Company in good faith. 

(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 (including share splits) as to which an adjustment was
effected pursuant to Section 14.04(a) or Section 14.04(b); 
 (ii)    rights issued pursuant to
a stockholders rights plan of the Company (other than pursuant to Section 14.11); 

(iii)    dividends or distributions paid exclusively in cash as to which an adjustment was effected
pursuant to Section 14.04(d); 
 (iv)    distributions of Reference Property in connection with a
Specified Corporate Event described below under Section 14.07; and 
 (v)    Spin-Offs as to which
the provisions set forth below in this Section 14.04(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 of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 

 
 

 

  
 65 

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date
for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined by the Company in good faith) of the Distributed Property so distributed 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 14.04(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 be the Conversion Rate that would then be in effect if
such dividend or 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 that 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. 
 With respect to an adjustment
pursuant to this Section 14.04(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: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;

  
 66 

					
	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 1.01 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, the 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 of such Spin-Off and the 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, the 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 of
such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, 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 shall be deemed replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last VWAP Trading Day of such Observation Period. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or
made, the Conversion Rate shall be immediately decreased, effective as of the on which the Board of Directors determines not to pay or make such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared or announced. 
 For purposes of this Section 14.04(c) (and subject in all respect to
Section 14.11), 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 for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will
be required) until the 

  
 67 

 
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 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, 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 14.04(c) was made: 

(A)    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 

(B)    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 14.04(a), Section 14.04(b) and this Section 14.04(c), any dividend or distribution to which this Section 14.04(c) is applicable that also includes one or both of: 

(i)    a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the
“Clause A Distribution”); or 
 (ii)    a dividend or distribution of rights, options or
warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”), 
 then: 

(A)    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 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(c) with respect to such Clause C
Distribution shall then be made; and 

  
 68 

 (B)    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 14.04(a) and Section 14.04(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) 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 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(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 increased 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;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

 Any increase made pursuant to this Section 14.04(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 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
shares 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. 

  
 69 

 (e)    If the Company or any of its Subsidiaries makes a payment in respect
of a tender or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the 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 (such date, the “Expiration
Date”), the Conversion Rate shall be increased based on the following formula: 
  
 

 
 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 Expiration Date;
			
	CR1	  	=	  	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 Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Company in good faith) 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 Expiration Date (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange
offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

 The increase to the Conversion Rate under this Section 14.04(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 

  
 70 

 
have elapsed between such Expiration Date of such tender or exchange offer and the 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 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 Expiration Date 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, with such lesser
number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date of such tender or exchange offer to, and including, last VWAP Trading Day of such Observation Period. 

In the event that the Company or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or
exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion Rate that
would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that have been effected. 

(f)    Notwithstanding anything to the contrary in this Section 14.04 or any other provision of this 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 14.02(h) based on an adjusted Conversion Rate for such
Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 14.04, 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)    All calculations and other determinations under this Article 14 shall be
made by the Company and all adjustments to the Conversion Rate shall be made to the nearest one-ten thousandth (1/10,000th) of a share. 

(h)    In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04,
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, the Company may
also (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 shares of Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights
to acquire shares of Common Stock) or 

  
 71 

 
similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall send to the Holder of each Note at its last address appearing on the
Note Register 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)    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. 

(j)    [Reserved.] 

(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 send
such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(l)    For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not
include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. 
 (m)    If, in connection with any adjustment to
the Conversion Rate as set forth in Section 14.03 or this Section 14.04, a Holder shall be deemed for U.S. federal tax purposes to have received a distribution and the Company determines it is required to collect withholding tax with
respect to any such deemed distribution, the Company may withhold from cash payments of interest in accordance with the provisions of Section 2.03 hereof or from cash and Common Stock, if any, otherwise deliverable to a Holder upon a conversion
of Securities in accordance with the provisions of Section 14.02 hereof or repurchase of a Security in accordance with the provisions of Article 15 hereof. 

Section 14.05. Adjustments of Prices. Whenever any provision of this 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, without limitation, an Observation Period and the period, if any, for determining the Stock Price for purposes of a
Make-Whole Fundamental Change or Optional Redemption), the Company shall make appropriate adjustments in its good faith judgment to each to account for any adjustment to 

  
 72 

 
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 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 14.06. Shares to Be Fully Reserved. The Company shall reserve, on or prior to the date of this Indenture, and from time to time as may be
necessary, out of its authorized but unissued shares, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming 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 is applicable, and including the maximum number of Additional Shares that could be included in the Conversion Rate for a conversion in connection with a
Make-Whole Fundamental Change). 
 Section 14.07. 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 in par
value or resulting from a subdivision or combination); 
 (ii)    any consolidation, merger or
combination involving the Company; or 
 (iii)    any sale, lease or other transfer to a third party of
all or substantially all of the Company’s and its Subsidiaries’ consolidated assets, taken as a whole; 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 “Specified Corporate Event” and any such stock, other securities, other property or assets (including cash or any combination thereof), “Reference Property” and
the amount of Reference Property that a holder of one share of the Common Stock immediately prior to such Specified Corporate Event would have been entitled to receive upon the occurrence of such Specified Corporate Event, a “Unit of
Reference Property”), then the Company, or the successor or purchasing corporation, as the case may be, will execute with the Trustee, without the consent of the Holders, a supplemental indenture providing that, at and after the effective
time of the Specified Corporate Event, the right to convert each $1,000 principal amount of Notes will be changed into a right to convert such principal amount of Notes into the kind and amount of Reference Property that a holder of a number of
shares of the Common Stock equal to the Conversion Rate immediately prior to such Specified Corporate Event would have been entitled to receive upon such Specified Corporate Event; provided, however, that at and after the effective
time of such Specified Corporate 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 14.02; and 

  
 73 

 (B)    (I) any amount payable in cash upon conversion of the
Notes in accordance with Section 14.02 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 14.02 shall
instead be deliverable in Units of Reference Property that a holder of that number of shares of Common Stock would have received in such Specified Corporate Event and (III) the Daily VWAP shall be calculated based on the value of a Unit of
Reference Property; provided, however, that if the holders of Common Stock receive only cash in such Specified Corporate Event, then for all conversions that occur after the effective time of such Specified Corporate Event (x) the
consideration due upon conversion of each $1,000 principal aggregate 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 14.03), multiplied by the price paid per share of Common Stock in such Specified Corporate Event and (y) the Company shall satisfy the Conversion Obligation by paying such cash to the converting Holder on the third Business
Day immediately following the Conversion Date. 
 If the Specified Corporate 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 the Reference Property used to calculate the Daily VWAP shall be deemed to be based on: (A) the
weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; and (B) if no holder of Common Stock affirmatively make such an election, the types and amounts of
consideration actually received by the holder of Common Stock. The Company shall notify, in writing, the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the weighted average of the types and amounts of consideration
received by the holders of Common Stock that affirmatively make such an election as soon as reasonably 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 14. If the Reference Property in respect of any Specified Corporate Event includes shares of stock, securities or other property or assets (including any
combination thereof) of a company other than the Company or the successor or purchasing corporation, as the case may be, in such Specified Corporate Event, then such other company shall also execute such supplemental indenture, and such supplemental
indenture shall contain such additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to repurchase their Notes in connection with a Fundamental Change in accordance with Article 15, as the
Board of Directors shall reasonably consider necessary by reason of the foregoing. 
 (b)    In the event the Company
shall execute a supplemental indenture pursuant to Section 14.07(a), 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 other assets
(including any combination thereof) that will comprise the Reference Property after any such 

  
 74 

 
Specified Corporate Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly send notice thereof to all Holders. The
Company shall cause notice of the execution of such supplemental indenture to be sent to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture. 
 (c)    [Reserved]. 

(d)    The Company shall not become a party to any Specified Corporate Event unless its terms are consistent with this
Section 14.07. 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 14.01 and Section 14.02 prior to the effective date of such Specified Corporate Event. 
 (e)    The
above provisions of this Section shall similarly apply to successive Specified Corporate Events. 
 Section 14.08. Certain Covenants. 

(a)    The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be duly authorized,
fully paid and non-assessable and free from all preemptive or similar rights of any securityholder of the Company and, except for any transfer taxes payable by the Company or a Holder, as the case may be,
pursuant to Sections 14.02(d) and 14.02(e), free from all transfer or similar taxes, liens, charges and adverse claims as the result of any action by the Company. 

(b)    The Company shall comply with all federal and state securities laws regulating the offer and delivery of shares of
Common Stock upon conversion of the Notes, including that if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state
law before such shares may be validly issued upon conversion, the Company shall, to the extent then permitted by the rules and interpretations of the Commission, 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 shall 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 14.09. 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 

  
 75 

 
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 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 14.07 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 14.07 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 7.01, 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 14.01(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 14.01(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 14.01(b). The parties hereto agree that all notices to the Trustee or the Conversion Agent under this Article 14 shall be in writing. 

Section 14.10. 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 14.04 or Section 14.11; 
 (b)    Specified Corporate Event or any consolidation, merger, sale,
assignment, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article 11; or 

(c)    voluntary or involuntary dissolution, liquidation or winding-up of the
Company; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause
to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be sent to each Holder at its address appearing on the Note Register, 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 Specified Corporate Event, any consolidation, merger, sale, assignment, lease, conveyance or other transfer
or disposition of all or substantially all assets in accordance with 

  
 76 

 
Article 11, or any dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Specified Corporate Event, consolidation, merger, sale, assignment, lease, conveyance or other transfer or disposition of
all or substantially all assets in accordance with Article 11, dissolution, liquidation or winding-up; provided, however, that if on such date, the Company does not have knowledge of such event
or the adjusted Conversion Rate cannot be calculated, the Company shall deliver such notice as promptly as practicable upon obtaining knowledge of such event or information sufficient to make such calculation, as the case may be, and in no event
later than the effective date of such adjustment. 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, Specified Corporate Event, or any
consolidation, merger, sale, assignment, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article 11, dissolution, liquidation or winding-up. 

Section 14.11. Stockholder Rights Plans. To the extent that the Company has a rights plan in effect upon conversion of the Notes into Common
Stock, Holders that convert their Notes shall receive, in addition to any shares of Common Stock received in connection with such conversion, the appropriate number of rights under the rights plan, if any, and any certificate representing the share
of 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 rights plan, as the same may be amended from time to time. However, if prior to any conversion, the rights have
separated from the shares of Common Stock in accordance with the provisions of the applicable 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 shares of
Common Stock, Distributed Property pursuant to Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

ARTICLE 15 

PURCHASE OF NOTES AT OPTION OF HOLDERS

 Section 15.01. Intentionally Omitted. 

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior to the
Maturity Date, 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 amount thereof that is equal to $1,000 or an integral
multiple of $1,000 thereof, on the date (the “Fundamental Change Repurchase Date,” which definition reflects postponement, if any, permitted by the last sentence of this Section 15.02(a)) specified by the Company that is not less
than 20 nor 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 

  
 77 

 
of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be purchased pursuant to this Article 15. The Fundamental
Change Repurchase Date shall be subject to postponement in order to allow the Company to comply with applicable law. 

(b)    Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon: 

(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 Certificated Notes, or in compliance with the Applicable 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 Certificated Notes, to the Paying Agent on or before the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the
Notes are Global Notes, in compliance with the Applicable Procedures, 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: 

A.    in the case of Certificated Notes, the certificate numbers of the Notes to be delivered for
repurchase; 
 B.    the portion of the principal amount of Notes to be repurchased, which must be $1,000
or an integral multiple of $1,000; and 
 C.    that the Notes are to be purchased by the Company
pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Fundamental Change Repurchase Notice must comply with the Applicable Procedures. 
 Notwithstanding anything herein to the contrary, any
Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02 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 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 15.03. 

If a Holder has already delivered a Fundamental Change Repurchase Notice with respect to a Note, such Holder may not surrender such Note for
conversion until such Holder has validly 

  
 78 

 
withdrawn such Fundamental Change Repurchase Notice (or, in the case of a Global Note, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with the terms
of Section 15.03. 
 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 Business Day after the occurrence of a
Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (if other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the Fundamental Change
and of the repurchase right at the option of the Holders arising as a result thereof. Each Fundamental Change Company Notice shall specify: 

(i)    the events causing the Fundamental Change; 

(ii)    the date the Fundamental Change became effective; 

(iii)    the last date on which a Holder may exercise the repurchase right pursuant to this Article 15;

 (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 other than the Trustee); 

(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 withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture (or, in the case of a Global Note, complies with the Applicable Procedures with respect to such a
withdrawal); and 
 (ix)    the procedures that Holders must follow to require the Company to repurchase
their Notes. 
 At the Company’s written request, 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. In such a case, the Company shall deliver such notice to the Trustee at least two
Business Days prior to the date that the notice is required to be given to the Holders (unless a shorter notice period shall be agreed to by the Trustee), together with an Officer’s Certificate requesting that the Trustee give such notice. 

  
 79 

 Such notice shall be delivered to the Trustee, to the Paying Agent (if other than the Trustee)
and to each Holder at its address shown in the Note Register (and to the beneficial owner as required by applicable law) or, in the case of Global Notes, in accordance with the Applicable Procedures. 

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 15.02. 

(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 Agent will promptly return to the respective Holders thereof any Certificated 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 Applicable Procedures 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. 

(e)    Notwithstanding the foregoing, the Company shall not be required to repurchase, or to make an offer to repurchase,
the Notes upon a Fundamental Change: 
 (i)     if a third party makes such an offer in the manner and at
the times required and otherwise in compliance with the requirements for an offer made by the Company pursuant to this Article 15 and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer on the
Fundamental Change Repurchase Date; or 
 (ii)    pursuant to clause (2) of the definition of
“Fundamental Change” (or a Fundamental Change pursuant to clause (1) of such definition which also results in a Fundamental Change pursuant to clause (2) of such definition) if (x) such Fundamental Change results in the
Notes becoming convertible (pursuant to the provisions described in clause 14.07) into an amount of cash per Note that is greater than the Fundamental Change Repurchase Price (assuming the maximum amount of accrued interest would be payable based on
the latest possible Fundamental Change Repurchase Date) and (2) the Company provides timely notice of the Holders’ right to convert their Notes based on such Fundamental Change as described under Section 14.01. 

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part)
by means of a written notice of withdrawal delivered to the Paying Agent in accordance with this Section 15.03 at any time 

  
 80 

 
prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

(a)    the principal amount of the Notes with respect to which such notice of withdrawal is being
submitted, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000, 

(b)    if Certificated Notes have been issued, the certificate number of the Notes in respect of which such
notice of withdrawal is being submitted, and 
 (c)    the principal amount, if any, of such Notes 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 withdrawal notice must comply with the Applicable Procedures. 

Section 15.04. Deposit of Fundamental Change Repurchase Price. (a) The Company shall 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 4.04) 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 purchased at the appropriate Fundamental Change Repurchase Price; provided, however, that to the extent any such deposit is received by the Trustee (or applicable Paying Agent)
after 11:00 a.m., New York City time on any Fundamental Change Repurchase Date, such deposit will be deemed deposited on the next Business Day. Subject to receipt of funds 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 Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date
with respect to such Note (provided the Holder has satisfied the conditions in Section 15.02) 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 15.02, 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. 
 (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 purchased on such Fundamental Change Repurchase Date, then, with respect
to Notes that have been properly tendered and not validly withdrawn: 
 (i)    such Notes shall cease to
be outstanding and interest shall 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 

(ii)    all other rights of the Holders of such Notes will terminate on the Fundamental Change Repurchase
Date (other than (x) the right to receive the Fundamental 

  
 81 

 
Change Repurchase Price and (y) if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment Date, the right of the Holder on
such Regular Record Date to receive the accrued and unpaid interest to, but not including, the Fundamental Change Repurchase Date). 

(c)    Upon surrender of a Note that is to be purchased in part pursuant to Section 15.02, the Company shall execute
and upon receipt of a Company Order, the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unpurchased portion of the Note surrendered, without payment of any service
charge. 
 Section 15.05. 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 that may then be applicable; 

(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 15 to be exercised in the time and in the manner
specified in this Article 15. To the extent that any securities laws or regulations conflict with the provisions of this Indenture relating to the Company’s obligations to repurchase Notes in connection with a Fundamental Change, the Company
shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Indenture by virtue of such conflict. 

ARTICLE 16 

OPTIONAL REDEMPTION 

Section 16.01. Optional Redemption. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company prior to
April 5, 2020. On or after April 5, 2020, the Company may redeem (an “Optional Redemption”) for cash all or any portion of the Notes, at the Redemption Price, if the Last Reported Sale Price of the Common Stock has been at
least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive), during any 30 consecutive Trading Day period ending on the Trading Day immediately preceding the date on which the Company provides the
Redemption Notice in accordance with Section 16.02. 
 Section 16.02. Notice of Optional Redemption; Selection of Notes. (a) In case
the Company exercises its Optional Redemption right to redeem all or any portion of the Notes pursuant to Section 16.01, it shall fix a date for redemption (each, a “Redemption Date”) and the Company or, at its written request
received by the Trustee not less than two Scheduled Trading Days prior to the date of the Redemption Notice (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall
deliver or cause to 

  
 82 

 
be delivered a notice of such Optional Redemption (a “Redemption Notice”) not less than 40 nor more than 55 Scheduled Trading Days prior to the Redemption Date to each Holder of
Notes so to be redeemed as a whole or in part, the Trustee and the Paying Agent (if other than the Trustee). The Redemption Date must be a Business Day, and the Company may not specify a Redemption Date that falls on or after the 32nd Scheduled
Trading Day immediately preceding the Maturity Date as determined by the Company. 
 (b)    The Redemption Notice, if
delivered in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption Notice to
the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. 

(c)    Each Redemption Notice shall be irrevocable and may not be conditional and shall specify: 

(i)    the Redemption Date; 

(ii)    the Redemption Price; 

(iii)    that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and
that interest thereon, if any, shall cease to accrue on and after the Redemption Date; 
 (iv)    the place or places
where such Notes are to be surrendered for payment of the Redemption Price; 
 (v)    that Holders may surrender their
Notes for conversion at any time prior to the close of business on the second Scheduled Trading Day immediately preceding the Redemption Date (unless the Company fails to pay the Redemption Price, in which case a Holder may convert such Notes until
the close of business on the Business Day immediately preceding the date on which the Redemption Price has been paid or duly provided for); 

(vi)    the procedures a converting Holder must follow to convert its Notes and the Settlement Method and Specified Cash
Amount, if applicable; 
 (vii)    the Conversion Rate and, if applicable, the number of Additional Shares added to the
Conversion Rate in accordance with Section 14.03; 
 (viii)    the CUSIP, ISIN or other similar numbers, if any,
assigned to such Notes; and 
 (ix)    in case any Note is to be redeemed in part only, the portion of the principal
amount thereof to be redeemed and on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued. 

  
 83 

 (d)    If fewer than all of the outstanding Notes are to be redeemed, the
Trustee shall select the Notes or portions thereof of a Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or integral multiples of $1,000 in excess thereof) by lot, on a pro rata basis or by another method
the Trustee considers to be fair and appropriate or as required by the rules and procedures of the applicable Depositary. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note
submitted for conversion shall be deemed (so far as may be possible) to be the portion selected for redemption. 
 Section 16.03. Payment of Notes
Called for Redemption. (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 16.02, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption
Notice and at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price. 

(b)    Prior to 11:00 a.m., New York City time, on the Redemption Date, the Company shall deposit with the Paying Agent
or, if the Company or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 4.04 an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to
pay the Redemption Price of all of the Notes to be redeemed on such Redemption Date; provided, however, that to the extent any such deposit is received by the Trustee (or applicable Paying Agent) after 11:00 a.m., New York City time on any
such due date, such deposit will be deemed deposited on the next Business Day. Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes. 

The Paying Agent shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the
Redemption Price and any amounts due and owing to the Trustee or Paying Agent. 
 (c)    Upon surrender of a Note that
is to be redeemed in part pursuant to this Article 16, the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the
unredeemed portion of the Note surrendered, without payment of any service charge. 
 Section 16.04. Restrictions on Redemption. The Company may
not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an
acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers and exchanges of Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06, Section 2.07,
Section 10.04, Section 15.04 and Section 16.03 as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication executed on behalf of the
Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve as trustee
hereunder pursuant to Section 7.08. 
 Any corporation or other entity into which any authenticating agent may be merged or converted
or with which it may be consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding to all or substantially
all the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section 17.11, without the execution or
filing of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 

Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at
any time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall mail notice of such
appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 

  
 87 

 The Company agrees to pay to the authenticating agent from time to time reasonable compensation
for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 7.06, Section 8.03 and this Section 17.11
shall be applicable to any authenticating agent.

and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all
purposes. 
 Section 17.13. Severability. In the event any provision of this Indenture or in the Notes shall be invalid, illegal or
unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired. 

Section 17.14. Waiver of Jury Trial; Submission of Jurisdiction. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY
SUBMITS TO THE JURISDICTION OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING

 Section 17.15. Force Majeure. In no event shall the Trustee be responsible or liable for any failure
or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military
disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that
are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

Section 17.16. Calculations. Except as otherwise provided herein, the Company shall be responsible for making all calculations called for under
the Notes or this Indenture. These calculations include, but are not limited to, determinations of the Stock Price or Trading Price, the Last Reported Sale Prices of the Common Stock, the Daily VWAPs, the Daily Conversion Values, the Daily
Settlement Amounts, accrued interest payable on the Notes and the Conversion Rate of the Notes. The Company shall make all these calculations in good faith and, absent manifest error, such calculations shall be final and binding on Holders of Notes.
The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of such calculations without independent
verification. The Trustee will forward the Company’s calculations to any Holder of Notes upon the written request of that Holder at the sole cost and expense of the Company. In no event shall the Trustee or the Conversion Agent be charged with
knowledge of or have any duty to monitor Stock Price or Measurement Period. Neither the Trustee nor the Conversion Agent shall have any responsibility for calculations or determinations of amounts, determining whether events requiring or permitting
conversion have occurred, determining whether any adjustment is required to be made with respect to conversion rights and, if so, how much, or for the delivery of shares of Common Stock. 

Section 17.17. U.S.A. Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the
Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or
opens an account with the Trustee. The parties to this Indenture agree that they will provide the Trustee with such information as is required to satisfy the requirements of the U.S.A. Patriot Act. 

Section 17.18. Tax Withholding. Notwithstanding any other provision of this Indenture, the Company or the Trustee, as the case may be,
shall be entitled to make a deduction or withholding from any payment which it makes under this Indenture for or on account of any present or future taxes, duties or charges if and to the extent so required by any applicable law and any current or
future regulations or agreements thereunder or official interpretations thereof or any law implementing an intergovernmental approach thereto or by virtue of the relevant Holder failing to satisfy any certification or other requirements in respect
of the Notes, in which event the Company or the Trustee, as the case may be, shall make such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted and shall
have no obligation to gross up any payment hereunder or pay any additional amount as a result of such withholding tax.

 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly
executed as of the date first written above.

 Exhibit A-5 

 [FORM OF REVERSE OF NOTE] 

CARBONITE, INC. 
 2.50% Convertible
Senior Note due 2022 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.50% Convertible Senior
Notes due 2022 (the “Notes”), limited to the aggregate principal amount of $143,750,000 all issued under and pursuant to an Indenture dated as of April 4, 2017 (the “Indenture”), between the Company and U.S.
Bank National Association, as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities
thereunder of the Trustee, the Conversion Agent, 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. The Notes represent that
aggregate principal amount of outstanding Notes from time to time endorsed hereon and the aggregate principal amount of outstanding Notes represented hereby may from time to time be increased or reduced to reflect purchases, cancellations,
conversions or transfers permitted by the Indenture. 
 In case an Event of Default, as defined in the Indenture, 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, the Redemption Price 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. Upon conversion
of any Note, the Company shall, at its election, pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock. 

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. 
 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 the principal (including the Fundamental Change Repurchase Price and
the Redemption Price, if applicable) of or the consideration due upon conversion of, as the case may be, and accrued and unpaid interest on this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed. 

  
 Exhibit A-6 

 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 shall not be redeemable at the Company’s option prior to April 5, 2020. On or after April 5, 2020, the Notes may be
redeemed by the Company, subject to the satisfaction of certain conditions and in accordance with the terms specified in the Indenture. 

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, at the
Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 
 Terms used in this Note and
defined in the Indenture are used herein as therein defined.
