restrictions on transfer set forth in this Section 2.05(c) (including those contained in the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder
of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any
sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
 Until the date (the “Resale Restriction
Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such
later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear
the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have 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 sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by
the Company in writing, with notice thereof to the Trustee): 
 THIS SECURITY AND THE COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS
SECURITY HAVE 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 

  
 17 








 (2)    AGREES FOR THE BENEFIT OF TEEKAY CORPORATION (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 HEREOF 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, OR 

(B)    PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C)    TO 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. 
 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. 

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on
the Form of Assignment and Transfer has been checked. 
 The Trustee and the Note Registrar 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 Note or any beneficial interest therein (including any transfers between or among
Depositary participants, members or beneficial owners 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. 

  
 18 








 Any Note (or security issued in exchange or substitution therefor) (i) as to which such
restrictions on transfer shall have expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to
be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Note for
exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this
Section 2.05(c) and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so surrender any Global Note as to which any of the conditions set forth in clause (i) through (iii)
of the immediately preceding sentence have been satisfied, 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 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 exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph. 

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for
Cede & Co. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as
depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days or
(iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be exchanged for a Physical Note, the Company shall execute, and the Trustee,
upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver, at the Company’s expense, (x) in the case of clause (iii), a Physical Note to such beneficial
owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related
Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be
canceled. 

  
 19 








 Physical 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, at the Company’s expense, such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon
receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical
Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase. 
 None of the Company, the Trustee, any Agent or any of their respective
agents shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary. 

None of the Trustee or any Agent shall have any responsibility or obligation to any beneficial owner of an interest in a Global Note, a member
of, or a participant in, the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant member thereof, with respect to any ownership interest in the Notes or with respect to the
delivery to any participant, member, beneficial owner or other person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount or delivery of any Notes (or other security or property) under or with
respect to such Notes. 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). 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 and each Agent 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 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 pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such Common Stock has been issued upon conversion of a Note that
has transferred pursuant to a 

  
 20 








 
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 pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to 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 TEEKAY CORPORATION (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 SERIES OF NOTES UPON THE CONVERSION OF WHICH THIS SECURITY
WAS ISSUED 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, OR 

(B)    PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 

(C)    TO 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. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN
ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMPANY’S COMMON STOCK 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. 

  
 21 








 Any such Common Stock (i) as to which such restrictions on transfer shall have expired in
accordance with their terms, (ii) that 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
(iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, 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
this Section 2.05(d). 
 (e)    Any Note or Common Stock issued upon the conversion or exchange of a Note that is
repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under
the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as
defined under Rule 144). The Company shall cause any Note that is repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) or owned by it to be surrendered to the Trustee for cancellation in accordance with
Section 2.08. 
 Section 2.06    Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall
become mutilated or be destroyed, lost or stolen, the Company shall execute, and upon Company Order 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. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of
such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, or any Agent upon the issuance of any substitute Note, but the Company
may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the
Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 14 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 

  
 22 








 
authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and,
in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Agent 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, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with
respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

Section 2.07    Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the
Trustee or an authenticating agent appointed by the Trustee shall, upon Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the
form of the Physical 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 Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such
authenticating agent Physical 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 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 Physical 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 Physical 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, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee
for cancellation. All Notes delivered to the Trustee for cancellation shall be canceled promptly by it, and no Notes shall be authenticated in exchange therefor 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. 

  
 23 








 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;
Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than
differences in the issue price and interest accrued prior to the issue date of such additional Notes and, if applicable, the initial Interest Payment Date) in an unlimited aggregate principal amount; provided that if any such additional Notes
are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a
Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 16.05, as the Trustee shall reasonably request. In
addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or
through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to
cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08 and such Notes shall no longer be considered outstanding under this Indenture upon their repurchase. 

ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01    Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an
Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes theretofore
authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company
has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Fundamental Change Repurchase Date or Redemption Date, upon conversion or otherwise, cash or cash,
shares of Common Stock or a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation, sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and
(b) the Company has delivered to the Trustee an Officers’ 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. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 

  
 24 








 ARTICLE 4 

PARTICULAR COVENANTS OF THE COMPANY 

Section 4.01    Payment of Principal and Interest. The Company covenants and agrees that it will cause to be
paid the principal (including the Fundamental Change Repurchase Price or Redemption Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the
Notes. 
 Section 4.02    Maintenance of Office or Agency. The Company will maintain in the Borough of
Manhattan, The City of New York, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation 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 (other than the type contemplated by Section 16.04) may be served. The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 

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

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, and Conversion Agent and the Corporate Trust Office
as the office or agency in the Borough of Manhattan, The City of New York, where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion and where notices and demands to or
upon the Company in respect of the Notes and this Indenture may be made. 
 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 Agents. (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 or Redemption Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 

  
 25 








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

(iii)    that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith
pay to the Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal (including the Fundamental
Change Repurchase Price or Redemption Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price or Redemption
Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such
deposit must be received by the Paying Agent by 10:00 a.m., New York City time, on such date. 
 (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 or Redemption Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate
and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price or 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 or Redemption Price, if applicable) of, 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 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 applicable abandoned property law, any money and shares of Common Stock deposited with the Trustee, any
Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price or Redemption Price, if applicable) of, accrued and unpaid interest on and the consideration due upon conversion
of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price or Redemption Price, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to
the Company on request of the Company contained in an Officers’ Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as


  
 26 








 
an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and shares of Common Stock, and
all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may (but shall not be obligated to) at the expense of
the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such money and shares of
Common Stock remain unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid or delivered
to the Company. 
 Section 4.05    Existence. Subject to Article 11, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 4.06    Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not
subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the
meaning of Rule 144(a)(3) under the Securities Act, upon written request, promptly provide to any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon conversion of such 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 shares of Common Stock pursuant to Rule 144A. 

(b)    The Company shall file with the Trustee, within 15 days after the same are required to be filed with the
Commission, 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 (giving effect to any grace period provided by Rule
12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this
Section 4.06(b) at the time such documents are filed via the EDGAR system, it being understood that the Trustee shall not be responsible for determining whether such filings have been made. 

(c)    Delivery of the reports and documents described above to the Trustee is for informational purposes only, and the
Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of the Company’s
covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). 

(d)    If, at any time during the six-month period beginning on, and including,
the date that is six months after the last date of original issuance of the Notes, 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), or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the
three months 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 at the 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 by Holders other than the Company’s Affiliates (or Holders that have
been the Company’s Affiliates at any time during the three months preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes. As used in this Section 4.06(d), documents or reports that the
Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the
Exchange Act. 
 (e)    If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c)
has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months
preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes, 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 in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP and the Notes are freely tradable
by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months preceding) (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the
Notes). 
 (f)    Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the
same manner and to the same Persons as regular interest on the Notes. 
 (g)    The Additional Interest that is payable
in accordance with Section 4.06 (d) or Section 4.06 (e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. The Trustee shall
have no duty to verify the Company’s determination of whether Additional Interest is due or the Company’s calculations as to the amount of Additional Interest. 

(h)    If Additional Interest is payable by the Company pursuant to Section 4.06 (d) or Section 4.06 (e), the
Company shall deliver to the Trustee an Officers’ 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 and promptly after any such
Additional Interest ceases to accrue and be payable, the Company shall deliver to the Trustee an Officers’ Certificate to that effect. 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. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’
Certificate setting forth the particulars of such payment. 
 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 or other law that
would prohibit or forgive the Company from paying all or any portion of the principal of 

  
 28 








 
or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company
(to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law had been enacted. 

Section 4.08    Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee
within 120 days after the end of each fiscal year of the Company (commencing with the fiscal year ending on December 31, 2018) an Officers’ Certificate stating whether the signers thereof have knowledge of any Default under this Indenture
and, if so, specifying each such Default and the nature thereof. 
 In addition, the Company shall deliver to the Trustee, as soon as
possible, and in any event within 30 days after the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or
proposing to take in respect thereof. 
 Section 4.09    Further Instruments and Acts. Upon request of the
Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 

Section 4.10    Additional Amounts. (a) All payments made by the Company under or with respect to the
Notes shall be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (hereinafter “Taxes”) imposed or levied by or on behalf
of the Republic of the Marshall Islands or any jurisdiction from or through which payment on the notes is made, or any political subdivision thereof, or any authority or agency thereof having power to tax (a “Taxing Jurisdiction”), unless
the Company is required to withhold or deduct Taxes by law or by the interpretation or administration thereof. If the Company is so required to withhold or deduct any amount of interest for or on account of Taxes from any payment made under or with
respect to the Notes, the Company shall pay such additional amounts of interest (“Additional Amounts”) as may be necessary so that the net amount received by each Holder (including Additional Amounts) after such withholding or deduction
shall not be less than the amount the Holder would have received if such Taxes had not been withheld or deducted; provided, however, that the Company will not pay any Additional Amounts in connection with any Taxes that are imposed due to any of the
following (“Excluded Additional Amounts”): 
 (i)    the Holder or beneficial owner has some connection with
the Taxing Jurisdiction other than merely holding the Notes or receiving principal or interest payments on the Notes (such as citizenship, nationality, residence, domicile, or existence of a business, a permanent establishment, a dependent agent, a
place of business or a place of management present or deemed present within the Taxing Jurisdiction); 
 (ii)     any
tax imposed on, or measured by net income; 

  
 29 








 (iii)    the Holder or beneficial owner fails to comply with any
certification, identification or other reporting requirements concerning its nationality, residence, identity or connection with the Taxing Jurisdiction, if (A) such compliance is required by applicable law, regulation, administrative practice
or treaty as a precondition to exemption from all or a part of the Tax, (B) the Holder or beneficial owner is able to comply with such requirements without undue hardship, and (C) at least 30 calendar days prior to the first payment date
with respect to which such requirements under the applicable law, regulation, administrative practice or treaty shall apply, the Company has notified such Holder that such Holder will be required to comply with such requirements; 

(iv)    the Holder fails to present (where presentation is required) its Note within 30 calendar days after the Company
has made available to the Holder a payment of principal or interest, provided that the Company will pay Additional Amounts which a Holder would have been entitled to had the Note owned by such Holder been presented on any day (including the last
day) within such 30-day period; or 
 (v)    any estate, inheritance, gift,
value added, use or sales Taxes or any similar Taxes. 
 (b)    The Company shall also (1) make such withholding or
deduction and (2) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Company shall furnish to the Trustee and the Holders of the Notes, within 30 days after the date the payment of any
Taxes are due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Company. 

(c)    The Company shall indemnify and hold harmless each Holder for the amount (other than Excluded Additional Amounts)
of (1) any Taxes not withheld or deducted by the Company and levied or imposed and paid by such Holder as a result of payments made under or with respect to the Notes, (2) any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, and (3) any Taxes imposed with respect to any reimbursement under clause (1) or (2) of this paragraph (c) of this Section 4.10. 

(d)    At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if
the Company is aware that it will be obligated to pay Additional Amounts with respect to such payment, the Company shall deliver to the Trustee an Officers’ Certificate stating the fact that such Additional Amounts will be payable, the amounts
so payable and such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date. Whenever in this Indenture or the Notes there is mentioned, in any context, the payment of principal (and premium,
if any), interest or any other amount payable under or with respect to any Note, such mention (except where expressly mentioned) shall be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.10 to the
extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

 Section 4.11    Anti-Money Laundering, Terrorism and Economic
Sanctions. 
 (a)    The Company covenants and represents that neither it nor any of its Affiliates, Subsidiaries,
directors or officers are the target or subject of any sanctions enforced by the U.S. Government, (including, without limitation, the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”) or the U.S. Department
of State), the United Nations Security Council, the European Union, Her Majesty’s Treasury, or other relevant sanctions authority (collectively “Sanctions”). 

(b)    The Company covenants and represents that neither it nor any of its Affiliates, Subsidiaries, directors or officers
will directly or indirectly use any repayments/reimbursements made pursuant to this Indenture (i) to fund or facilitate any activities of or business with any person who, at the time of such funding or facilitation, is the subject or target of
Sanctions, (ii) to fund or facilitate any activities of or business with any country or territory that is the target or subject of sanctions, or (iii) in any other manner that will result in a violation of Sanctions by any Person.

30 days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably
require of the names and addresses of the Holders as of a date not more than 15 days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no
such list need be furnished so long as the Trustee is acting as Note Registrar. 
 Section 5.02    Preservation

(g)    default by the Company or any Subsidiary of the Company with respect to any mortgage, agreement or other instrument
under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $50,000,000 (or its foreign currency equivalent) in the aggregate of the Company and/or any such Subsidiary,
whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and

 32 








 Section 6.02    Acceleration; Rescission and Annulment. If one or
more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court
or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its
Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the outstanding Notes by notice to
the Company and the Trustee, may, and the Trustee at the request of Holders of at least 25% in aggregate principal amount of the outstanding Notes shall, declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due
and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default
specified in Section 6.01(i) or Section 6.01(j) with respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and
shall automatically be immediately due and payable. 
 The immediately preceding paragraph, however, is subject to the conditions that if,
at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of
accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 7.06, and if
(1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid
interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of
a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its
consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any
subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default
resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price or Redemption Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when
required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 

Section 6.03    Additional Interest. 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 

  
 33 








 
relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall after the occurrence of such an Event of Default consist exclusively of the right
to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during the 60-day period on which such Event of Default is
continuing beginning on, and including, the date on which such an Event of Default first occurs. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to
Section 4.06(d) or Section 4.06(e). If the Company so elects, such Additional Interest shall be payable in the same manner, to the same Persons and on the same dates as the stated interest payable on the Notes. On the 61st day after such
Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 61st day), the Notes shall be immediately subject to acceleration as provided in Section 6.02. The provisions of this
paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 4.06(b). In the event the Company does
not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to
acceleration as provided in Section 6.02. 
 In order to elect to pay Additional Interest as the sole remedy during the first 60 days
after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 60-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 

Section 6.04    Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause
(a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest,
if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes 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 moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any
other obligor upon the Notes, wherever situated. 
 In the event there shall be pending proceedings for the bankruptcy or for the
reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, 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 or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon
the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be 

  
 34 








 
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 or any other obligor on the Notes, its or their creditors,
or its or their 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, 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 pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 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. 

  
 35 








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

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price or Redemption Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the
overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole
amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price or Redemption Price and the cash due upon conversion) and interest without preference or priority of
principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the
Fundamental Change Repurchase Price or Redemption Price and any cash due upon conversion) and accrued and unpaid interest; and 

Fourth, to the payment of the remainder, if any, to the Company. 

Section 6.06    Proceedings by Holders. Except to enforce the right to receive payment of principal
(including, if applicable, the Fundamental Change Repurchase Price or Redemption Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue
of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other
similar official, or for any other remedy hereunder, unless: 
 (a)    such Holder previously shall have given to the
Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 

  
 36 








 (b)    Holders of at least 25% in aggregate principal amount of the Notes
then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder; 

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

(e)    no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given
to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09, 

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that
no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and
enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder to receive payment or delivery,
as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price or Redemption Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such
Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the
Company shall not be impaired or affected without the consent of such Holder. 
 Section 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. 

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 

  
 37 








 
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. The Holders of a
majority of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 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 the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) 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 it determines is in conflict with any rule of law or this Indenture, is unduly prejudicial to
the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may on behalf of the
Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase
Price or Redemption Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or
(iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders
of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default
hereunder shall have been waived as permitted by this Section 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, the Trustee shall, within 90 days after a Responsible Officer is deemed to have actual knowledge of a Default, send to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of such Default, unless such
Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Fundamental Change Repurchase Price or Redemption Price, if
applicable), or accrued and unpaid interest on, any of the Notes 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 Responsible
Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

  
 38 








 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 determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the
Fundamental Change Repurchase Price or Redemption Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon
conversion, in accordance with the provisions of Article 14. 
 ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.01    Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of
Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In the event an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such
person’s own affairs; provided that if an Event of Default occurs and is continuing, 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 or security reasonably satisfactory to the Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or direction. The Trustee shall have no
liability for failing to act if it has not received indemnity or security reasonably satisfactory to it, any instruction or notice required by or contemplated by the Notes or this Indenture, or any legal opinion required to be delivered to the
Trustee or for which the Trustee has a right to request as contemplated by this Indenture or the Notes. 
 No provision of this Indenture
shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct, except that: 

(a)    prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may
have occurred: 
 (i)    the duties and obligations of the Trustee shall be determined solely by the express provisions
of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the
Trustee; and 

  
 39 








 (ii)    in the absence of bad faith and willful misconduct on the part of the
Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture;
but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 

(b)    the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers
of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 

(c)    the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in
accordance with the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 8.04 relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 

(d)    whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the
liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section; 
 (e)    the
Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes; 
 (f)    if any party fails to deliver a
notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a
Responsible Officer of the Trustee had actual knowledge of such event; 
 (g)    all cash received by the Trustee shall
be placed in a non-interest bearing trust account, and all cash shall remain uninvested unless otherwise agreed in writing by the Company and the Trustee; and 

(h)    in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid
Solicitation Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or
transfer agent. 

  
 40 








 None of the provisions contained in this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. The Trustee shall not be required to give any bond or surety in respect of the performance of
its powers or duties hereunder.

parties;

(d)    the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the
Company and shall incur no liability of any kind by reason of such inquiry or investigation; 
 (e)    the Trustee may
execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any
agent, custodian, nominee or attorney appointed by it with due care hereunder; 
 (f)    the permissive rights of the
Trustee enumerated herein shall not be construed as duties; 
 (g)    the Trustee shall be under no obligation to
exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee
against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 

(h)    the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and
reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 

  
 41 








 (i)    the rights, privileges, protections, immunities and benefits given to
the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, each Agent and each other agent, custodian and other Person employed to act
hereunder; 
 (j)    the Trustee may request that the Company deliver an Officers’ Certificate setting forth the
names of individuals and/or titles of Officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any
person specified as so authorized in any such certificate previously delivered and not superseded; and 
 (k)    the
Trustee shall not be obligated to take possession of any Common Stock, whether upon conversion or in connection with any discharge of this Indenture pursuant to Article 3 hereof, but shall satisfy its obligation as Conversion Agent by working
through the stock transfer agent of the Company from time to time as directed by the Company. 
 In no event shall the Trustee be liable for
any consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. The Trustee shall not be charged
with knowledge of any Default or 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 the Trustee by the Company or by any Holder of the Notes. 
 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 and the Agents assume no
responsibility for the correctness of the same. The Trustee and the Agents make no representations as to the validity or sufficiency of this Indenture or of the Notes or of any Common Stock. The Trustee and the Agents shall not be accountable for
the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. Neither the Trustee nor any Agent will be accountable for the use or
application by the Company of the Notes or the proceeds thereof, or for any funds received and disbursed in accordance with this Indenture. The Trustee and the Agents shall have no responsibility or liability with respect to any information,
statement or recital in the Offering Memorandum or other disclosure material prepared or distributed with respect to the issuance of the Notes. 

Section 7.04    Trustee or Agents May Own Notes. The Trustee or any Agent, 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 or such Agent. 

Section 7.05    Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for
interest on any money received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 

  
 42 








 Section 7.06    Compensation and Expenses of Trustee. The Company
covenants and agrees to pay to the Trustee, in any capacity under this Indenture, from time to time, and the Trustee shall be entitled to, reasonable 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 own gross negligence, willful misconduct or bad faith. The Company also covenants to indemnify the
Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its officers, directors, employees and agents and any authenticating agent for, and to hold them harmless against, any loss,
claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith 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 of liability in the premises. 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. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier
resignation or removal or 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. 
 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(i) or Section 6.01(j) 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    Officers’ 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 gross negligence, willful misconduct or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to
the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct or bad faith 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. 

  
 43 








 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, 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. 
 Section 7.09    Resignation or Removal of Trustee.
(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and by giving notice thereof to the Holders in accordance with Section 16.03. 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 60 days after the giving of such notice of resignation to the Holders, the resigning Trustee may, 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 (or since the date of this Indenture) may, subject to the provisions of
Section 6.11, on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee. 
 (b)    In case at any time any of the following shall occur: 

(i)    the Trustee shall 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 
 (ii)    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 either 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 (or since the date of this Indenture) may, on behalf of himself or herself 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. 

  
 44 








 (c)    The Holders of a majority in aggregate principal amount of the Notes
at the time outstanding, as determined in accordance with Section 8.04, 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, in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment
of a successor trustee. 
 (d)    Any resignation or removal of the Trustee and appointment of a successor trustee
pursuant to any of the provisions of this Section 7.09 shall become effective upon 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; but, nevertheless,
on the written request of the Company or of the successor trustee, the trustee ceasing to act 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, 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 give or cause to be given notice of the succession of such trustee hereunder to the Holders in accordance with
Section 16.03. If the Company fails to give such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be given 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. 

  
 45 








 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 shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate 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. 
 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 to the Company 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 that the Company has indicated to the Trustee should receive such application 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. 

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 (a) 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 (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) 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. 

  
 46 








 Section 8.02    Proof of Execution by Holders. Subject to the
provisions of Section 7.01, Section 7.02 and Section 9.05, 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. The record of any Holders’ meeting shall be proved in the
manner provided in Section 9.06. 
 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 under this Indenture; 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. The sole registered Holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, 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 Physical Note 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, by any Subsidiary thereof or by any Affiliate of the Company or any Subsidiary thereof shall be
disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action
only Notes 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, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to
such right, any decision or indecision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and
identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officers’ Certificate as
conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

  
 47 








 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 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.

 Any meeting of Holders shall be valid without notice if the Holders of all Notes then outstanding
are present in person or by proxy or if notice is waived before or after the meeting by the Holders of all Notes then outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the
meeting, waived notice. 
 Section 9.03    Call of Meetings by Company or Holders. In case at any time the
Company, pursuant to a Board Resolution, or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not have given the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and the place for such
meeting and may call such meeting to take any action authorized in Section 9.01, by giving notice thereof as provided in Section 9.02. 

Section 9.04    Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall

Persons who shall be entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its counsel and any representatives of the Company
and its counsel. 
 Section 9.05    Regulations. Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment and duties of inspectors of votes, the

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting shall be elected by vote of the Holders of a majority in aggregate principal amount of the outstanding Notes represented at the meeting and entitled to vote at the meeting. 

Subject to the provisions of Section 8.04, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each
$1,000 principal amount of Notes held or represented by him or her; provided, however, that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting
to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of
Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not

all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the
aggregate principal amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to
the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 

Any record so signed and verified shall be conclusive evidence of the matters therein stated. 

Section 9.07    No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be deemed or
construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to

this Indenture pursuant to Article 11; 
 (c)    to add guarantees with respect to the Notes;

(e)    to add to the covenants or Events of Default of the Company for the benefit of the Holders or surrender any right
or power conferred upon the Company; 
 (f)    to make any change that does not adversely affect the rights of any
Holder; 

  
 50 








 (g)    in connection with any Merger Event, provide that the notes are
convertible into Reference Property, subject to the provisions of Section 14.02, and make such related changes to the terms of the Notes to the extent expressly required by Section 14.07; or 

(h)    to conform the provisions of this Indenture or the Notes to the “Description of Notes” section of the
Offering Memorandum. 
 Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by the
provisions of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 10.02    Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in
Article 8) of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or
tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental
hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided,
however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall:

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

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

(g)    change the ranking of the Notes; 

  
 51

interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes; or 

(i)    make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in
Section 6.02 or Section 6.09. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the
consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be
sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall send to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such
notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture. 

Section 10.03    Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant
to the provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee,
the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to
be part of the terms and conditions of this Indenture for any and all purposes. 
 Section 10.04    Notation on
Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such
supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 16.10) and delivered in exchange for
the Notes then outstanding, upon surrender of such Notes then outstanding. 
 Section 10.05    Evidence of
Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by Section 16.05, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements of this Article 10 and is permitted or authorized by this Indenture.

 ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01    Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of
Section 11.02, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless: 

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

(b)    immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be
continuing under this Indenture; and 
 (c)    the Company delivers to the Trustee an Officers’ Certificate and
Opinion of Counsel certifying that all conditions in this Indenture to such transaction (and the execution of any supplemental indenture) have been satisfied. 

For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of
one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated
basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 11.02    Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale,
conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued
and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company,
with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable
hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes
that such Successor Company thereafter shall cause to be signed and delivered to the 

  
 53 








 
Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with
the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (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 (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any
time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes. 

Section 11.03    Opinion of Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance,
transfer or lease shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption
and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11. 

ARTICLE 12 

IMMUNITY OF INCORPORATORS, SHAREHOLDERS, OFFICERS AND DIRECTORS 

Section 12.01    Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the
principal of or accrued and unpaid interest on 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 successor corporation, either directly or through the Company or any successor corporation, 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 execution of this Indenture and the issue of the Notes. 

ARTICLE 13 

REDEMPTION 

Section 13.01    Optional Redemption. The Notes shall not be redeemable by the Company at its option prior to
January 15, 2021. On or after January 15, 2021, the Company may redeem (an “Optional Redemption”) for cash all, but not less than all, of the then outstanding Notes, at its option and 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), including the Trading Day immediately preceding the date on which the Company provides a
Redemption Notice, during any 30 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date on which the Company provides the Redemption Notice in accordance with Section 13.02. The Conversion Rate
with respect to Notes converted after the Company gives notice of an Optional Redemption may be increased as described in Section 14.03. 

  
 54 








 Section 13.02    Notice of Optional Redemption. (a) In case
the Company exercises its Optional Redemption right to the Notes pursuant to Section 13.01, it shall fix a date for redemption (each, a “Redemption Date”) and it or, at its written request received by the Trustee not less than
35 Scheduled Trading Days prior to the Redemption Date (or such shorter period of time as may be acceptable to the Trustee), accompanied by the form of the Redemption Notice described below, the Trustee, in the name of and at the expense of the
Company, shall deliver or cause to be delivered a notice of such Optional Redemption (a “Redemption Notice”) not less than 30 nor more than 50 Scheduled Trading Days prior to the Redemption Date to the Trustee, the Paying Agent and
each Holder of Notes so to be redeemed. The Company may not give a notice of Redemption during the final 30 Scheduled Trading Days prior to the Maturity Date. 

(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. 
 (c)    Each Redemption Notice 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 Business Day immediately preceding the Redemption Date; 

(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; and 
 (viii)    the CUSIP, ISIN or other similar numbers, if
any, assigned to such Notes. 
 Substantially concurrently with the issuance of a Redemption Notice, the Company will issue a press release containing the
information contained in such notice and make such information available on its website. A Redemption Notice shall be irrevocable. 

Section 13.03    Payment of Notes Called for Redemption. (a) If any Redemption Notice has been given in
respect of the Notes in accordance with Section 13.02, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice 

  
 55 








 
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. The Redemption Price shall be calculated by the Company, or the Company shall cause the Redemption Price to be calculated on its behalf. 

(b)    No later than 10:00 a.m. Eastern 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. 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 and interest on Notes redeemed
shall cease to accrue on and after the Redemption Date and all rights of the Holders of such Notes shall terminate (other than the right to receive the applicable Redemption Price). 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. 

Section 13.04    Restrictions on Redemption. The Company may not redeem any Notes on any date if there has
been an Event of Default as a result of which 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). 

ARTICLE 14 

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 July 15, 2022 under the circumstances and during the periods set forth in
Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), at any time on or after July 15, 2022 and prior to the close of business on the second Business Day immediately preceding the Maturity Date,
in each case, at an initial conversion rate of 85.4701 shares of Common Stock (subject to adjustment as provided in this Article 14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with,
the settlement provisions of Section 14.02, the “Conversion Obligation”). 
 (b)    (i) Prior to
the close of business on the Business Day immediately preceding July 15, 2022, a Holder may surrender all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading
Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the
Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on each such Trading Day and the Conversion Rate 

  
 56 








 
on each such Trading Day. The Trading Prices shall be determined by the Company pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture and the Bid
Solicitation Agent (if other than the Company) shall have no obligation to determine any Trading Prices. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally
recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each and shall direct such securities dealers to provide the required information to the Bid
Solicitation Agent. The Bid Solicitation Agent shall have no obligation to obtain bids unless the Company has requested that the Bid Solicitation Agent do so, and the Company shall have no obligation to make such request or to determine the Trading
Price of the Notes unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock
on such Trading Day and the Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent to obtain bids (in accordance with the definition of Trading Price set forth in this Indenture), and the Company
shall determine the Trading Price per $1,000 principal amount of Notes, in each case, beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes, as determined by the Company, is
greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If the Company does not instruct the Bid Solicitation Agent (if other than the Company) to obtain bids when obligated as
provided in the preceding sentence, if the Company instructs the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent fails to obtain bids, or the Company fails to determine the Trading Price when obligated as provided in the
preceding sentence, then, in each case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such
failure. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Bid Solicitation Agent (if other than the Company), the Trustee and the Conversion Agent (if other than the Trustee). If, at any time
after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for
such date, the Company shall so notify the Holders of the Notes, the Bid Solicitation Agent (if other than the Company), the Trustee and the Conversion Agent (if other than the Trustee) in writing. None of the Trustee, the Bid Solicitation Agent or
the Conversion Agent shall have any duty to determine or verify the Company’s determination of whether the Trading Price condition set forth above has been met. 

(ii)    If, prior to the close of business on the Business Day immediately preceding July 15, 2022, the Company
elects to: 
 (A)    issue to all or substantially all holders of the Common Stock any rights, options or warrants
entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices
of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

  
 57 








 (B)    distribute to all or substantially all holders of the Common Stock
the Company’s assets, securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on
the Trading Day preceding the date of announcement for such distribution, 
 then, in either case, the Company shall notify all Holders of the Notes, the
Trustee and the Conversion Agent (if other than the Trustee) in writing at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such
notice, a Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for
such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time. None of the Trustee, the Bid Solicitation
Agent or the Conversion Agent shall have any duty to determine or verify the Company’s determination of whether an issuance or distribution as described in this clause (ii) has occurred. 

(iii)    If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior
to the close of business on the Business Day immediately preceding July 15, 2022, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a
consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, then in each case all or any
portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 35 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Company
gives notice of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify
Holders, the Trustee and the Conversion Agent (if other than the Trustee) (x) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 35 Scheduled Trading Days prior to the
anticipated effective date of such transaction or (y) if the Company does not have knowledge of such transaction at least 35 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date
upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction. None of the Trustee, the Bid Solicitation Agent or the Conversion Agent shall have any
duty to determine or verify the Company’s determination of whether Fundamental Change or a Make-Whole Fundamental Change has occurred. 

(iv)    Prior to the close of business on the Business Day immediately preceding July 15, 2022, a Holder may
surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on March 31, 2018 (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. The 

  
 58 








 
Company, shall determine at the beginning of each calendar quarter commencing after March 31, 2018 whether the Notes may be surrendered for conversion in accordance with this clause
(iv) and shall notify the Conversion Agent and the Trustee if the Notes become convertible in accordance with this clause (iv). None of the Trustee, the Bid Solicitation Agent or the Conversion Agent shall have any duty to determine or verify
the Company’s determination of whether the condition described in this described in this clause (iv) has occurred. 

(v)    If the Company gives a Redemption Notice with respect to an Optional Redemption of the Notes pursuant to Article
13, 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 Business Day prior to the Redemption Date, even if the Notes are not otherwise convertible at such time. After
that time, the right to convert shall expire pursuant to this clause, 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 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 pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if
applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with
cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Combination Settlement”), at its election, as set forth in this Section 14.02.

 (i)    All conversions (i) for which the relevant Conversion Date occurs on or after July 15, 2022 or
(ii) after the Company has given a Redemption Notice pursuant to Article 13 shall, in each case, be settled using the same Settlement Method. 

(ii)    Except as provided in clause (i) above, the Company shall use the same Settlement Method for all conversions
with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates. 

(iii)    If, in respect of any Conversion Date (or the period described in the third immediately succeeding set of
parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the
Trustee, shall deliver such Settlement Notice to converting Holders no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or (i) in the case of any conversions for which the relevant
Conversion Date occurs on or after July 15, 2022, no later than July 15, 2022 and (ii) in the case of any conversion of Notes after the Company has given a Redemption Notice pursuant to Article 13, the date such Redemption Notice is
given). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the 

  
 59 








 
Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion
Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant
Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified
Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. 

(iv)    Subject to Section 14.01(j), the cash, shares of Common Stock or combination of cash and shares of Common
Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 

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

(B)    if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the
Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive Trading Days during the related
Observation Period; and 
 (C)    if the Company elects (or is deemed to have elected) to satisfy its Conversion
Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily
Settlement Amounts for each of the 25 consecutive Trading Days during the related Observation Period. 
 (v)    The
Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts
or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily
Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no
responsibility for any such determination. 
 (b)    Subject to Section 14.02(e), before any Holder of a Note shall
be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest
Payment Date to which such Holder is not entitled as set forth in Section 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver 

  
 60 








 
an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion
Agent and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the
Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish
appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.02(h). 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. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such
Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.02. 

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes
shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c)    A Note shall be deemed to have been converted immediately prior to the close of business on the date (the
“Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.03(b) Section 14.07(a) and Section 14.07(a), the Company shall pay or
deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second Business Day
immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the
Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the 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 Note shall be surrendered for partial conversion, the
Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted
portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar
governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such
conversion. 
 (e)    If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar
issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued 

  
 61 








 
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 or refuse to instruct the stock transfer agent to deliver the
certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding
sentence. 
 (f)    Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares of
Common Stock issued upon the conversion of any Note as provided in this Article 14. 
 (g)    Upon the conversion of an
interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of
any conversion of Notes effected through any Conversion Agent other than the Trustee. 
 (h)    Upon conversion, a
Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the
principal amount of the Note and accrued and unpaid interest, if any, to, but 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 cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion.
Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date and prior to the open of business on the corresponding Interest Payment Date, Holders of such Notes as of the close of business on such
Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any
Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required
(1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the Business Day immediately following
the corresponding Interest Payment Date; (3) 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 (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note or to the extent of any Additional Amounts. Therefore, for the avoidance of doubt, all Holders of record on
the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date regardless of whether their Notes have been converted following such Regular Record Date. 

(i)    The Person in whose name the certificate for any shares of Common Stock shall be issuable upon conversion shall be
treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if


  
 62 








 
the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes
surrendered for conversion. 
 (j)    The Company shall not issue any fractional share of Common Stock upon conversion
of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for
the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued upon
conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash. 

Section 14.03    Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole
Fundamental Changes or a Notice of Redemption. (a) If (i) a Make-Whole Fundamental Change occurs or becomes effective prior to the Maturity Date or (ii) the Company gives a Redemption Notice pursuant to Article 13, and in each 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 Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date
(or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole
Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). A conversion of Notes will be deemed for these purposes to be “in connection with” a Redemption Notice if the relevant Notice of Conversion is
received by the Conversion Agent from, and including, the date the Redemption Notice is given (the “Redemption Notice Date”), until the close of business on the second Business Day preceding the Redemption Date. 

(b)    Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or a Redemption Notice as
described in clause (a) above, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.02; provided, however,
that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any
conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000
principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the second


  
 63 








 
Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole
Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

(c)    The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by
reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) or the Redemption Notice Date, as the case may be, and the price (the “Stock
Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or on the Redemption Notice Date, as the case may be. If the holders of the Common Stock receive in exchange for their Common Stock only
cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices
of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or the Redemption Notice Date, 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, Effective Date (as such term is used in Section 14.04) or expiration date of the event occurs during such five consecutive Trading Day period. 

(d)    The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the
Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to
such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as
the Conversion Rate as set forth in Section 14.04. 
 (e)    The following table sets forth the number of
Additional Shares of Common Stock 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 or Redemption Notice Date, as applicable, set forth
below:

 The exact Stock Prices and Effective Dates or Redemption Notice Dates, as applicable, may not be
set forth in the table above, in which case: 
 (i)    if the Stock Price is between two Stock Prices in the table above
or the Effective Date or Redemption Notice Date, as applicable, is between two specified dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for
the higher and lower Stock Prices and the earlier and later specified dates, as applicable, based on a 365-day year; 

(ii)    if the Stock Price is greater than $35.00 per share (subject to adjustment in the same manner as the Stock Prices
set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii)    if the Stock Price is less than $9.75 per share (subject to adjustment in the same manner as the Stock Prices set
forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 102.5641 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 (x) a share split or share combination or (y) a
tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes,
as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

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

					
	 CR’ = CR0 ×
  
	 	 OS’
	 	
	 	OS0	 	

 where, 
  

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


  
 65 









					
	CR’	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date, before giving effect to such dividend, distribution,
share split or share combination; and
			
	OS’	  	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 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 but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b)    If the
Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase 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, the Conversion Rate shall be increased based on the following formula: 
  

							
	 	 	CR’ = CR0 × 	 	OS0+X	 	 
	 	 	 	OS0+Y	 	 

  

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


  
 66 








 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 the 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 for
the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale
Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common
Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined
by the Board of Directors. 
 (c)    If the Company distributes shares of its Capital Stock, evidences of its
indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances
as to which an adjustment was provided for pursuant to Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash, as to which the provisions set forth in Section 14.04(d) shall apply, and
(iii) 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, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
  

							
	 	 	CR’ = CR0 × 	 	SP0	 	 
	 	 	 	SP0 - FMV	 	 

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the
Ex-Dividend Date for such distribution;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution;

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

 Any increase made under the portion of this Section 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 the Conversion Rate that would then be in effect
if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the
foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed
Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors
determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market
over the same period used in computing the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the
Ex-Dividend Date for such distribution. 
 With respect to an adjustment pursuant to this
Section 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: 
  

							
	 	 	CR’ = CR0 × 	 	FMV0+MP0	 	 
	 	 	 	MP0	 	 

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of
Last Reported Sale Price as set forth in Section 1.01 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


  
 68 









					
			
	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 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 reference to “10” in the preceding paragraph shall be
deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such 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 reference to “10” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. 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 to be 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 such Spin-Off to, and including, the last Trading Day of such Observation Period. 
 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 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, (1) in the
case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options
or warrants had not been issued and 

  
 69 








 
(y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal
to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock
as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such
rights, options and warrants had not been issued. 
 For purposes of Section 14.04(a), Section 14.04(b) and this
Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of: 

(A)    a dividend or distribution of shares of Common Stock to which Section 14.04(a) is applicable (the
“Clause A Distribution”); or 
 (B)    a dividend or distribution of rights, options or warrants to
which Section 14.04(b) is applicable (the “Clause B Distribution”), 
 then, in either case, (1) such dividend or distribution,
other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 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 (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion
Rate adjustment required by Section 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, other than a
regular, quarterly cash dividend that does not exceed $0.055 per share per quarter (the “Initial Dividend Threshold”), the Conversion Rate shall be adjusted based on the following formula: 

 

							
	 	 	CR’ = CR0 × 	 	SP0-T	 	 
	 	 	 	SP0-C	 	 

 where, 
  

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


  
 70 









					
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	T	  	=	  	the Initial Dividend Threshold; provided that if the dividend or distribution is not a regular quarterly cash dividend, the Initial Dividend Threshold shall be deemed to be zero; and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

 The Initial Dividend Threshold shall be subject to adjustment in a manner inversely proportional to
adjustments to the Conversion Rate; provided that no adjustment shall be made to the Initial Dividend Threshold for any adjustment to the Conversion Rate pursuant to this Section 14.04(d). Any increase 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 be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.
Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of 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. 

(e)    If the Company or any of its Subsidiaries make 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, the Conversion Rate shall be increased based on the following formula: 

 

							
	 	 	 CR’ = CR0 × 
	  	AC+(SP’×OS’)	  	 
	 	 	  	    OS0×SP’	  	 

 where, 
  

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


  
 71 









					
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the expiration of such tender or exchange offer (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer);
			
	OS’	  	=	  	the number of shares of Common Stock outstanding immediately after the expiration of such tender or exchange offer (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer); and
			
	SP’	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 The increase to the Conversion Rate under this Section 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 have elapsed between the expiration date of such tender or exchange offer and such Conversion Date in determining the Conversion Rate and (y) in respect of any
conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the
Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the
expiration date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the date such tender or exchange offer expires is after the 10th Trading
Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in
respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and including, the last Trading Day of such Observation
Period. 
 (f)    Notwithstanding this Section 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(i) based on an adjusted Conversion 

  
 72 








 
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)    Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common
Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 

(h)    In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04,
and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a
period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on
which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a
dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall give to the Holder of
each Note in accordance with Section 16.03 a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be
in effect. 
 (i)    Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be
adjusted: 
 (i)    upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for
the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

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

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

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

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

  
 73 








 (j)    All calculations and other determinations under this Article 14 shall
be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. 

(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 Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the
Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume 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 give
such notice of such adjustment of the Conversion Rate to each Holder in accordance with Section 16.03. 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 of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

Section 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 an Observation Period and the period for determining the Stock Price), the Board of
Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the
Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts are to be calculated. 
 Section 14.06    Shares to Be Fully Paid. The Company
shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion
(assuming delivery of the maximum number of Additional Shares pursuant to Section 14.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were
applicable). 
 Section 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 resulting from a
subdivision or combination), 

  
 74 








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

 in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets
(including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to
convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion
Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a
holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a
supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of the Merger Event
(A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.02, (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 the units of Reference Property and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property, and (C) the conditions to conversion under Sections
14.01(b)(i) or (iv) and the conditions to Optional Redemption in Section 13.01, will be determined as if each reference to a share of Common Stock were instead a reference to a unit of Reference Property. 

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of
Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common
Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of
Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.03), multiplied by the price paid per share of Common


  
 75 








 
Stock in such Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant
Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that
shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any
combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions
to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15. 

(b)    When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.07, the
Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Merger Event,
any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly give notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be
given to each Holder in accordance with Section 16.03 within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

(c)    The Company shall not become a party to any Merger Event unless its terms are consistent with this
Section 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 Article 14
and Section 14.02 prior to the effective date of such Merger Event. 
 (d)    The above provisions of this Section
shall similarly apply to successive Merger Events. 
 (e)    In connection with any Merger Event, the Initial Dividend
Threshold shall be subject to adjustment as described in clause (i), clause (ii) or clause (iii) below, as the case may be. 

(i)    In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection
(a) above and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock (the “Merger Common Stock”), the Initial Dividend Threshold at and after the effective time of such Merger Event will
be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, divided by (y) the number of shares of Merger Common Stock that a holder of one share of Common Stock would receive in such
Merger Event (such quotient rounded down to the nearest cent). 

  
 76 








 (ii)    In the case of a Merger Event in which the Reference Property
(determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed in part of shares of Merger Common Stock, the Initial Dividend Threshold at and after the effective time of such
Merger Event will be equal to (x) the Initial Dividend Threshold immediately prior to the effective time of such Merger Event, multiplied by (y) the Merger Valuation Percentage for such Merger Event (such product rounded down to the
nearest cent). 
 (iii)    For the avoidance of doubt, in the case of a Merger Event in which the Reference Property
(determined, as appropriate, pursuant to subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other than shares of common stock, the Initial Dividend Threshold at and after the
effective time of such Merger Event will be equal to zero. 
 Section 14.08    Certain Covenants.
(a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to
the issue thereof. 
 (b)    The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted
by the rules and interpretations of the 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 will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes. 

Section 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 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 

  
 77 








 
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 conclusively relying upon, the Officers’ Certificate
and Opinion of Counsel (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). 

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)    Merger Event; or 

(c)    voluntary or involuntary dissolution, liquidation or winding-up of the
Company or any of its Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this
Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be given to each Holder in accordance with Section 16.03, as promptly as possible but in any event at least 20 days
prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which
the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or
winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company
or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear
such

legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the
rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially
all holders of the Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

ARTICLE 15 

REPURCHASE OF NOTES AT OPTION OF HOLDERS 

Section 15.01    Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change
occurs at any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on
the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase
Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such
Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. 

(b)    Repurchases of Notes under this Section 15.01 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 Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the
Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and 

(ii)    delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the
Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of
the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 

The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state: 

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

  
 79 








 (ii)    the portion of the principal amount of Notes to be repurchased, which
must be $1,000 or an integral multiple thereof; and 
 (iii)    that the Notes are to be repurchased by the Company
pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the
Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.01 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 15.02, in the case of Physical Notes, or through the
applicable procedures of the Depositary, in the case of Global Notes. 
 The Paying Agent shall promptly notify the Company of the receipt
by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 
 (c)    On or before the
20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the
“Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice
shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the
information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that
time. Each Fundamental Change Company Notice shall specify: 
 (i)    the events causing the Fundamental Change; 

(ii)    the date of the Fundamental Change; 

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

(iv)    the Fundamental Change Repurchase Price; 

(v)    the Fundamental Change Repurchase Date; 

  
 80 








 (vi)    the name and address of the Paying Agent and the Conversion Agent, if
applicable; 
 (vii)    if applicable, the Conversion Rate and any adjustments to the Conversion Rate as a result of the
Fundamental Change; 
 (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; and 

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.01. 
 At the Company’s 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. 

(d)    Notwithstanding the foregoing, the Company will not be required to repurchase, or to make an offer to repurchase or
notice thereof, the Notes upon a Fundamental Change if (i) it has given a Redemption Notice with respect to the Notes in accordance with Article 13, unless it defaults in making payments with respect to such redemption, or (ii) a third
party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above and such third party purchases all Notes properly surrendered and not validly
withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by the Company as set forth above. Such third party’s failure to repurchase the Notes will not relieve the
Company of its obligation to effect a repurchase as set forth above. 
 (e)    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 Physical Notes held by
it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer
of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have
been withdrawn. 
 Section 15.02    Withdrawal of Fundamental Change Repurchase Notice. (a) A
Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in 

  
 81 








 
accordance with this Section 15.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

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

(ii)    if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of
withdrawal is being submitted, and 
 (iii)    the principal amount, if any, of such Note that remains subject to the
original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 

Section 15.03    Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the
Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or prior to 10:00 a.m., New York City time, on the Fundamental
Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by
the Company), payment for Notes surrendered for repurchase (and not 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 (provided the Holder has satisfied the conditions in Section 15.01) 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 15.01 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 10:00 a.m. New York City time, on the Fundamental
Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with
respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn in accordance with the provisions of this Indenture, (i) such Notes will cease to be outstanding, (ii) interest will cease to
accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than (x) the
right to receive the Fundamental Change Repurchase Price and (y) if 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, the right of
the Holder of record on such Regular Record Date to receive the related interest payment). 

  
 82 








 (c)    Upon surrender of a Note that is to be repurchased in part pursuant to
Section 15.01, the Company shall execute and, upon Company Order, the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

 Section 15.04    Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any
repurchase upon a Fundamental Change, the Company will, if required: 
 (a)    comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 

(b)    file a Schedule TO or any other required schedule under the Exchange Act; and 

(c)    otherwise comply with all federal and state securities laws in connection with any offer by the Company to
repurchase the Notes; 
 in each case, so as to permit the rights and obligations under this Article 15 to be exercised in the time and in the manner
specified in this Article 15.

Section 16.04    Governing Law; Jurisdiction; Service of Process. THIS INDENTURE AND EACH NOTE SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

appoint a successor agent for this purpose reasonably acceptable to the Trustee, and provide written notice of such appointment to the Trustee in the manner provided herein. The Company agrees to take any and all actions as may be necessary to

Section 2.05, Section 2.06, Section 2.07, Section 10.04 and Section 15.04 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

appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 

  
 86 








 The Company agrees to pay to the authenticating agent from time to time reasonable compensation

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 7.06, Section 8.03 and this Section 16.10
shall be applicable to any authenticating agent.

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 16.13    Waiver of Jury Trial. 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. 

Section 16.14    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

 Section 16.15    Calculations. Except as otherwise provided
herein, the Company shall be responsible for making all calculations called for under the Notes. These calculations include, but are not limited to, determinations of the Trading Price of the Notes, 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, the
Company’s 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 the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of Notes upon the request of that Holder at the sole cost and expense of the
Company. 
 Section 16.16    USA PATRIOT Act. The parties hereto acknowledge that in accordance with
Section 326 of the USA PATRIOT Act, the Trustee (in all capacities), 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 it may request in order for the Trustee to satisfy the
requirements of the USA PATRIOT Act. 
 Section 16.17    Conversion of Currency. The Company covenants and
agrees that the following provisions shall apply to conversion of currency in the case of the Notes and this Indenture in the event the Company is in default under the terms of this Indenture: 

(a)    If for the purpose of obtaining judgment in, or enforcing the judgment of, any court in any country, it becomes
necessary to convert into a currency (the “judgment currency”) an amount due in U.S. Dollars, then the conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which the judgment is given or the
order of enforcement is made, as the case may be (unless a court shall otherwise determine). 
 (b)    If there is a
change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given or an order of enforcement is made, as the case may be (or such other date as a court shall determine), and the date of receipt of the
amount due, the Company will pay such additional amount (or, as the case may be, be refunded such lesser amount), if any, as may be necessary so that the amount paid in the judgment currency when converted at the rate of exchange prevailing on the
date of receipt will produce the amount in U.S. Dollars originally due. 
 (c)    In the event of the winding-up of the Company at any time while any amount of damages owing under the Notes of this Indenture, or any judgment or order rendered in respect thereof, shall remain outstanding, the Company shall indemnify
and hold the Holders and the Trustee harmless against any deficiency arising or resulting from any variation in rates of exchange between (1) the date as of which the equivalent of the amount in U.S. Dollars due or contingently due under the
Notes and this Indenture (other than under this Subsection (c)) is calculated for the purposes of such winding-up and (2) the final date for the filing of proofs of claim in such winding-up. For the purpose of this Subsection (c), the final date for the filing of 

  
 88 








 
proofs of claim in the winding-up of the Company shall be the date fixed by the liquidator or otherwise in accordance with the relevant provisions of
applicable law as being the latest practicable date as at which liabilities of the Company may be ascertained for such winding-up prior to payment by the liquidator or otherwise in respect thereto. 

(d)    The obligations contained in Subsections (b) and (c) of this Section 16.17 shall constitute separate and
independent obligations of the Company from its other obligations under the Notes and this Indenture, shall give rise to separate and independent causes of action against the Company, shall apply irrespective of any waiver or extension granted by
any Holders or the Trustee or any of them from time to time and shall continue in full force and effect notwithstanding any judgment or order or the filing of any proof of claim in the winding-up of the
Company for a liquidated sum in respect of amounts due hereunder (other than under subsection (c) above) or under any such judgment or order. Any such deficiency as aforesaid shall be deemed to constitute a loss suffered by the Holders or the
Trustee, as the case may be, and no proof or evidence of any actual loss shall be required by the Company or the liquidator or otherwise or any of them which shall be liable for such deficiency. In the case of Subsection (c) above, the amount
of such deficiency shall not be deemed to be reduced by any variation in rates of exchange occurring between the said final date and the date of any liquidating distribution. 

(e)    The term “rate(s) of exchange” shall mean the rate of exchange pursuant to the Noon Day Buying Rate
quoted by the Federal Reserve Bank of New York or, if such rate is not then available therefrom, the WM/Reuters Intraday Spot Rate quoted by WM/Reuters or any similar rate of exchange quoted by a successor exchange rate service at 12:00 noon (New
York City time) for the purchase of, or conversion into, U.S. Dollars from the judgment currency other than U.S. Dollars referred to in subsections (a) and (c) above and includes any premiums and costs of exchange payable. 

(f)    The Trustee shall have no duty or liability with respect to monitoring or enforcing this Section 16.17 and
shall have no liability to the Holders due to fluctuations in currency rates.

 [FORM OF REVERSE OF NOTE] 

Teekay Corporation. 
 5.000%
Convertible Senior Note due 2023 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 5.000%
Convertible Senior Notes due 2023 (the “Notes”) issued or to be issued under and pursuant to an Indenture dated as of January 26, 2018 (the “Indenture”), between the Company and The Bank of New York Mellon (the
“Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and
the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective
meanings set forth in the Indenture. 
 In case certain Events of Default shall have occurred and be continuing, the principal of, and
interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to
the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will
make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent
to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the
Fundamental Change Repurchase Price or Redemption Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or shares
of Common Stock or a combination thereof, as the case may be, herein prescribed. 

  
 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 are subject to redemption at the option of the Company on or after January 15, 2021 as provided in Article 13 of 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 Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of
Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
