execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding. 

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the

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

None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of
(i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not
withdrawn) in accordance with Article 15. 
 All Notes issued upon any registration of transfer or exchange of Notes in accordance with this
Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth
paragraph from the end of Section 2.05(c), all 

  
 17 








 
Notes shall be represented by one or more Notes in global form, without interest coupons (each, a “Global Note”) registered in the name of the Depositary or the nominee of the

(including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. 
 (c) Notwithstanding any other
provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated

Depositary and in compliance with this Section 2.05(c). 
 The Depositary shall be a clearing agency registered under the Exchange Act.
The Company initially appoints The Depository Trust Company to act as 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

 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 issued as a
Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a
Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each
beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee
such Global Notes shall be canceled. 
 Physical Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and
authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

  
 18 








 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. 
 Neither the
Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining,
supervising or reviewing any records relating to such beneficial ownership interests. 
 (d) The Company shall cause any Note that is
repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 
2.08. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration
number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of
the ownership thereof. 
 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, the Note Registrar, any co-Note Registrar or the Paying
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 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 

  
 19 








 
payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them
harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion
Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 Every substitute Note
issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note
shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent
permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall
preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their
surrender. 
 Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company
may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized
denomination, and substantially in the form of the 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 will 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 shall be canceled promptly by it, and no Notes shall be authenticated in exchange thereof 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 

  
 20 








 
such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order. If the Company shall acquire any of the Notes, such
acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 

Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if
then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will 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 and with the same CUSIP number as the Notes initially issued hereunder 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 will have one or more separate CUSIP numbers. Prior to the
issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to
those required by Section 17.05, 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. 

ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained
in an Officer’s 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 (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust
or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with
the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date or upon conversion or otherwise, cash and shares of Common Stock (solely to satisfy
the Company’s Conversion Obligation, if applicable), sufficient to pay or convert all of the outstanding Notes and to pay all other sums due and payable under 

  
 21 








 
this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive.

 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, 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 United States of
America or the District of Columbia, 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 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. 
 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 United States of America or the District of Columbia, 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, Custodian and Conversion Agent and the Corporate
Trust Office and the office or agency of the Trustee in Minneapolis, Minnesota, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 

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. 

  
 22 








 Section 4.04. Provisions as to Paying Agent. (a) If
the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section
4.04: 
 (i) that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental
Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 

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

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

  
 23 








 (d) Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including
the Fundamental Change Repurchase Price, if applicable) or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and shares of
Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease. 
 Section 4.05.
Existence. Subject to Article 11, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 

Section 4.06. Annual Reports. 

(a) 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(a) as of the time such documents are filed via the EDGAR system; provided,
however, that the Trustee shall have no obligation to determine whether such filing has occurred. 
 (b) Delivery of the reports and
documents described in subsection (a) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information
contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate). 

Section 4.07. 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 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 (beginning with the fiscal year ending on December 31, 2014) an Officer’s Certificate
indicating 

  
 24 








 
whether or not the signers thereof have knowledge of any failure by the Company to comply with all conditions and covenants then required to be performed under this Indenture and, if so,
describing each such failure and its status. 
 In addition, the Company shall deliver to the Trustee within 30 days after the Company
becomes aware of the occurrence of any Event of Default or Default, an Officer’s 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 with respect
thereto. 
 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. 

ARTICLE 5 

LISTS OF HOLDERS 

Section 5.01. Lists of Holders. The Company covenants and agrees that it will furnish or cause to be
furnished to the Trustee, semi-annually, not more than 15 days after each June 15 and December 15 in each year beginning with December 15, 2014, and at such other times as the Trustee may request in writing, within 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 and
Disclosure of Lists. The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in Section 5.01
or maintained by the Trustee in its capacity as Note Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished. 

ARTICLE 6 

DEFAULTS AND REMEDIES 

Section 6.01. Events of Default. The following events shall be “Events of Default”
with respect to the Notes: 
 (a) default for a period of 30 days in payment of any interest when due and payable on the Notes; 

  
 25 








 (b) default in the payment of principal of the Notes when due and payable on the Maturity Date or
upon any required repurchase upon the occurrence of a Fundamental Change, when the same becomes due and payable; 
 (c) failure by the
Company to issue a Fundamental Change Company Notice in accordance with Section 15.02(c) or a Make-Whole Adjustment Event Company Notice in accordance with Section 14.03(b), in each case when due, and such failure continues for a period of
five calendar days from the relevant due date; 
 (d) failure by the Company to comply with its obligation to convert the Notes in
accordance with this Indenture upon exercise of a Holder’s conversion right and such failure continues for a period of five Business Days following the scheduled settlement date; 

(e) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any
indebtedness for money borrowed by the Company or any Significant Subsidiary of the Company, whether such indebtedness exists on the date of this Indenture or is created hereafter, if such default (i) is caused by a failure to pay at its stated
maturity the principal of any such debt prior to the expiration of any grace period provided in such indebtedness as of the date of such default (a “payment default”) or (ii) results in such indebtedness becoming or being
declared due and payable, and in the case of (i) and (ii) above, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a payment default or the maturity
of which has been so accelerated aggregates $10.0 million or more unless such payment default is cured or waived or such acceleration is rescinded, stayed or annulled within 30 days after the date of such payment default or acceleration; 

(f) default in the Company’s performance of any of its other covenants or agreements in respect of the Notes contained in this Indenture
or the Notes for 60 days after written notice of such default has been received from the Trustee by the Company or from the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by the Company and the Trustee to comply;

 (g) the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or
other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or
other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other
proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or 

(h) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation,
reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other 

  
 26 








 
similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any
substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 60 consecutive days. 

Section 6.02. Acceleration; Rescission and Annulment. In case 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(g) or Section 6.01(h) with respect to the Company), unless the principal of all of the
Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company (and
to the Trustee if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest, if any, 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 in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 6.01(g) or Section 6.01(h) with respect to the Company occurs and is continuing,
100% of the principal of, and accrued and unpaid interest on, all Notes shall be automatically and immediately due and payable. 
 This
provision, 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, and on such principal at the rate borne by the Notes) 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 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. 

  
 27 








 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 relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(a) shall,
for the first 180 days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at an annual rate equal to (x) 0.25% of the principal amount of the Notes outstanding during
the first 90 days after which such Event of Default occurs and is continuing and (y) 0.50% of the principal amount of the Notes outstanding for the following 90 days beginning on the 91st day after which such Event of Default occurs and is
continuing. Additional Interest payable pursuant to this Section 6.03 shall be payable in the same manner and on the same dates as regular interest on the Notes. Additional Interest payable pursuant to this Section 6.03 upon the
Company’s election shall accrue from and including the date on which such Event of Default relating to the Company’s failure to file first occurs to, but excluding, the 180th day thereafter (or such earlier date on which such Event of
Default is cured or waived). On the 181st 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 181st day), the Notes will be subject to acceleration as provided
in Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elects to make such payment but does not pay the Additional Interest when
due, the Notes shall 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 180 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 180-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 

Notwithstanding the foregoing, in no event shall the amount of Additional Interest the Company elects to pay pursuant to this
Section 6.03 exceed 0.50% per annum regardless of the number of events that give rise to the obligation or election to pay any such Additional Interest. 

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 it, 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. 

  
 28 








 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 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 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 the 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. 

  
 29 








 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 such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in
such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted. 

Section 6.05. Application of Monies Collected by Trustee. Any monies collected by the Trustee

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 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

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

(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 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 in 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 (but subject to the provisions of Article 13), the right
of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest 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. 

  
 31 








 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 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 in 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 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
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) 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 deliver 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. 

  
 32 








 Section 6.10. Notice of Defaults. The Trustee shall,
within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, send to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of all Defaults known to a
Responsible Officer, 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,
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 the Trustee in good
faith determines that the withholding of such notice is in the interests of the Holders. 
 Section 6.11.
Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right
or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10%
in principal amount of the Notes at the time outstanding 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 with respect to the Notes being repurchased as provided in this Indenture) 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 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 case an Event of Default has occurred that
has not been cured or waived 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 their 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 

  
 33 








 
Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or
direction. 
 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:

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 
 (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 in 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; 

  
 34 








 (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 such Responsible Officer of the Trustee had actual knowledge of
such event; 
 (g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a
non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses, costs, fees or other charges incurred thereon or for losses incurred as a result of the liquidation of any
such investment prior to its maturity date or the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall
have no obligation to invest or reinvest any amounts held hereunder in the absence of such written investment direction from the Company; and 

(h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion 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, or transfer agent. 

None of the provisions contained in this Indenture shall require the Trustee to incur any personal financial liability or risk its own funds
in the performance of any of its duties or in the exercise of any of its rights or powers. 

Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01:

 (a) the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, Note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

(c) the Trustee may consult with counsel of its selection and require an Opinion of Counsel and any advice of such counsel or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(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


  
 35 








 
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) in no event shall the Trustee be liable for any consequential, indirect, special
or punitive 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; 

(h) 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; 

(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, and each agent, custodian and other Person employed to act hereunder; 

(j) the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder; and 

(k) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized
at such time to take specified actions pursuant to this Indenture. 
 Section 7.03. No Responsibility
for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated
and delivered by the Trustee in conformity with the provisions of this Indenture. 
 Section 7.04.
Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same
rights it would have if it were not the Trustee, Paying Agent, Conversion Agent or Note Registrar. 

  
 36 








 Section 7.05. Monies and Shares of Common Stock to Be Held
in Trust. All monies and shares of Common Stock received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common Stock held by the Trustee in
trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money or shares of Common Stock received by it hereunder except as may be agreed in writing
from time to time by the Company and the Trustee. 
 Section 7.06. Compensation and Expenses of
Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements
and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (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 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 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 (whether asserted by the Company, a Holder or any other Person) 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(g) or Section 6.01(h) occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws. 

  
 37 








 Section 7.07. Officer’s Certificate as Evidence.
Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct and bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officer’s Certificate delivered to the Trustee, and such Officer’s Certificate, in the absence of gross negligence, willful misconduct and 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. 

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 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 sending notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have
been so appointed and have accepted appointment within 60 days after the sending of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition, at the
Company’s expense, any court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on
behalf of himself or herself and all others similarly situated, petition, at the Company’s expense, 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 

  
 38 








 (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 may, on behalf of himself or herself and all others similarly situated, petition, at the Company’s expense, 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. 

(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, at the Company’s expense, 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. 

  
 39 








 No successor trustee shall accept appointment as provided in this Section 7.10 unless at the
time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of
appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall send or cause to be sent notice of the succession of such
trustee hereunder to the Holders at their addresses as they shall appear on the Note Register. If the Company fails to send such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such
notice to be sent at the expense of the Company. 
 Section 7.11. Succession by Merger, Etc. Any
corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing
of any paper or any further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or
other entity shall be eligible under the provisions of Section 7.08. 
 In case at the time such successor to the Trustee shall succeed to
the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by
such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may
authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates 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 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 

  
 40 








 
(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 in 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 fix, but shall not be required to, in advance of such solicitation, a date as the record date for
determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 

Section 8.02. Proof of Execution by Holders. Subject to the provisions of Section 7.01,
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; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All
such payments or deliveries so made to any Holder 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 

  
 41 








 
or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this
Indenture. 
 Section 8.04. Company-Owned Notes Disregarded. In determining whether the Holders of
the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with 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 a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee
taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to
be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in 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.

$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

written reports in duplicate of 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 sent as provided in Section 9.02.

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.

 44 








 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 the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes.

that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

  
 45 








 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.

It shall be sufficient if such consent approves 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, with respect to
amendments that do not require the consent of Holders, 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. Every amendment to this Indenture or the Notes shall be set forth in a supplemental indenture hereto that complies with the Trust Indenture Act as then in
effect. 
 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

(a) the surviving Person formed by such consolidation or into which the Company is merged or the Person to which the Company’s assets are
so transferred (the “Successor Company”), if not the Company, shall either be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor

and conditions of this Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and 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

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, 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 

  
 48 








 
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. 
 In case of any such consolidation, merger, sale, conveyance, lease or transfer, such
changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 
Section 11.03. Opinion of Counsel to Be Given to Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as

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.

exchange thereof, accepts and agrees to be bound by such provisions. 
 The payment of the principal of and interest on all Notes
(including, but not limited to, the Fundamental Change Repurchase Price in accordance with Article 15, but excluding the settlement of the Conversion Obligation in accordance with Article 14) issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full in cash or other payment satisfactory to the holders of all Senior Debt, whether outstanding at the date of this Indenture or thereafter incurred.


  
 49 








 No provision of this Article 13 shall prevent the occurrence of any Default or Event of Default
hereunder. 
 Section 13.02. Payment to Holders. No payment shall be made with respect to the
principal of or interest on the Notes (including, but not limited to, the Fundamental Change Repurchase Price in accordance with Article 15, but excluding the settlement of the Conversion Obligation in accordance with Article 14), except payments
and distributions made by the Trustee as permitted by the first or second paragraph of Section 13.05, if: 
 (i) a
default in the payment of principal, premium, interest or other amounts due on any Senior Debt, or in respect of any redemption or repurchase obligation under any Senior Debt, occurs and is continuing (or, in the case of Senior Debt for which there
is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Senior Debt) (a “Payment Default”); or 

(ii) a default, other than a Payment Default, on any Senior Debt occurs and is continuing that then permits holders of such
Senior Debt (or any Representative) to accelerate its maturity (a “Non-Payment Default”) and a Responsible Officer of the Trustee receives at the Corporate Trust Office a written notice of the default (a “Payment Blockage
Notice”) from the Company or a Representative of Senior Debt. 
 Notwithstanding the foregoing, following the delivery of a Payment
Blockage Notice to a Responsible Officer of the Trustee, no new Payment Blockage Notice may be delivered and no new period of payment blockage with respect to the Notes may begin until both (i) 360 consecutive days have elapsed since the
Company’s receipt of the first Payment Blockage Notice and (ii) all scheduled payments of principal of and interest with respect to the Notes that have come due have been paid in full in cash. No default that existed or was continuing on
the date of delivery to the Trustee of any Payment Blockage Notice with respect to the Senior Debt whose holders delivered the Payment Blockage Notice may be made the basis of a subsequent Payment Blockage Notice by the holders of such Senior Debt,
whether or not within a period of 360 consecutive days. 
 The Company may and shall resume payments on the Notes upon: 

(i) in the case of a Payment Default, the date upon which the default is cured or waived or ceases to exist, and 

(ii) in the case of a Non-Payment Default, on the earlier to occur of (A) the date on which such default is cured or
waived or otherwise ceases to exist, or (B) 179 days after the date on which the applicable Payment Blockage Notice is received unless the maturity of such Senior Debt has been accelerated, in which case no payment or distribution may be made
on the Notes until such default is cured or waived or such Senior Debt is discharged or paid in full. 

  
 50 








 In the event of any distribution to creditors of the Company: 

(i) in any liquidation or dissolution of the Company (whether voluntary or involuntary); 

(ii) in bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property;

 (iii) in an assignment for the benefit of creditors; or 

(iv) in any marshaling of the Company’s assets and liabilities, 

all amounts due or to become due upon all Senior Debt shall first be paid in full in cash, or other payments satisfactory to the holders of
Senior Debt before any payment of cash, property or securities (subject to Section 13.06) is made on account of the principal of or interest on the Notes as set forth above (except, to the extent required by applicable law, payments made
pursuant to Article 3 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such events set forth in (i)-(iv) above), to which the Holders of the Notes or the Trustee would be entitled, except for the
provision of this Article 13, shall (except as aforesaid) be paid by the Company, or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders or by the Trustee under
this Indenture if received by them or it, directly to the holders of Senior Debt (pro rata to such holders on the basis of the respective amounts of Senior Debt held by such holders, or as otherwise required by law or a court order) or their
representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Debt may have been issued, as their respective interests may appear, to the extent necessary to pay all
Senior Debt in full in cash, or other payment satisfactory to the holders of Senior Debt, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt, before any payment or distribution is made to the Holders
of the Notes or to the Trustee. 
 For purposes of this Article 13, the words, “cash, property or securities” shall not be deemed
to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other entity provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided
in this Article 13 with respect to the Notes to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the Senior Debt is assumed by the new entity, if any, resulting from any reorganization or readjustment, and
(ii) the rights of the holders of Senior Debt (other than leases which are not assumed by the Company or the new entity, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the sale, conveyance, lease or transfer of all or substantially all its property


  
 51 








 
to another Person upon the terms and conditions provided for in Article 11 shall not be deemed a liquidation or dissolution or reorganization for the purposes of this Section 13.02 if such
other Person shall, as a part of such consolidation, merger, sale, conveyance, lease or transfer, comply with the conditions stated in Article 11. 

In the event of the acceleration of the Notes because of an Event of Default, no payment or distribution shall be made to the Trustee or any
Holder of Notes in respect of the principal of or interest on the Notes (including, but not limited to, the Fundamental Change Repurchase Price in accordance with Article 15, but excluding the settlement of the Conversion Obligation in accordance
with Article 14), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 13.05 until all Senior Debt has been paid in full in cash or other payment satisfactory to the holders of Senior
Debt or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt of such acceleration. 

In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character,
(including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Notes before all Senior Debt is paid in full, in cash or other payment satisfactory to the holders of
Senior Debt, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of Senior Debt, such payment or distribution shall be held in trust for the benefit of and shall be paid
over or delivered to the holders of Senior Debt or their Representative or Representatives, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Debt remaining unpaid to the extent
necessary to pay all Senior Debt in full, in cash or other payment satisfactory to the holders of Senior Debt or their Representative, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Debt. 

Nothing in this Section 13.02 shall apply to claims of, or payments to, the Trustee under or pursuant to Sections 6.05 and 7.06. This
Section 13.02 shall be subject to the further provisions of Sections 13.05 and 13.06. 

Section 13.03. Subrogation of the Notes. Subject to the payment in full, in cash or other payment
satisfactory to the holders of Senior Debt, of all Senior Debt, the rights of the Holders of the Notes shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Debt pursuant to the provisions of this
Article 13 (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company to substantially the same extent as the Notes are subordinated and is entitled to
like rights of subrogation) to the rights of the holders of Senior Debt to receive payments or distributions applicable to the Senior Debt until the principal of and interest on the Notes shall be paid in full in cash; and, for the purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt to which the Holders of the Notes or the Trustee would be entitled except for the provisions of this Article 13, and no payment over pursuant to the provisions of this
Article 13, to or for the benefit of the holders of Senior Debt by 

  
 52 








 
Holders of the Notes or the Trustee, shall, as between the Company, its creditors other than holders of Senior Debt, and the Holders of the Notes, be deemed to be a payment by the Company to or
on account of the Senior Debt; and no payment or distribution to or for the benefit of the Holders of the Notes pursuant to the subrogation provisions of this Article 13, which would otherwise have been paid to the holders of Senior Debt shall be
deemed to be a payment by the Company to or for the account of the Notes. It is understood that the provisions of this Article 13 are and are intended solely for the purposes of defining the relative rights of the Holders of the Notes, on the one
hand, and the holders of the Senior Debt, on the other hand. 
 Nothing contained in this Article 13 or elsewhere in this Indenture or in
the Notes is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Debt, and the Holders of the Notes, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Notes
the principal of and interest on the Notes as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Notes and creditors of the Company other than
the holders of the Senior Debt. 
 Upon any payment or distribution of assets of the Company referred to in this Article 13, the Trustee,
subject to the provisions of Section 7.01, and the Holders of the Notes shall be entitled to conclusively rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation
or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Notes, for the
purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article
13. 
 Section 13.04. Authorization to Effect Subordination. Each Holder of a Note by the
Holder’s acceptance thereof authorizes and directs the Trustee on the Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 13 and appoints the Trustee to act as
the Holder’s attorney-in-fact for any and all such purposes. 
 Section 13.05. Notice to
Trustee. The Company shall give prompt written notice in the form of an Officer’s Certificate to a Responsible Officer of the Trustee and to any Paying Agent of any fact known to the Company that would prohibit the making of any payment of
monies to or by the Trustee or any Paying Agent in respect of the Notes pursuant to the provisions of this Article 13. Notwithstanding the provisions of this Article 13 or any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any payment of monies to or by the Trustee in respect of the Notes pursuant to the provisions of this Article 13, unless and until a Responsible Officer of the Trustee shall
have received written notice thereof at the applicable Corporate Trust Office from the Company (in the form of an Officer’s Certificate) or a Representative or a holder or holders of Senior Debt or from any trustee thereof; and before the
receipt of any such written notice, the Trustee, subject to the provisions of Section 7.01, shall be entitled in all respects to assume that 

  
 53 








 
no such facts exist; provided that, if on a date not less than one Business Day prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including,
without limitation, the payment of the principal of or interest on any Note) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 13.05, then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or
after such prior date. Notwithstanding anything in this Article 13 to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Article 3, and any such payment shall not be subject to the
provisions of this Article 13; provided that, at the time of any such deposit, such deposit and payment were permitted under this Article 13 without giving effect to the first clause this sentence; provided further that, if the Trustee shall
receive any such notice on the date upon which, by the terms hereof, such monies shall be payable, the Trustee may, in its reasonable discretion, waive the foregoing proviso. 

The Trustee, subject to the provisions of Section 7.01, shall be entitled to conclusively rely on the delivery to it of a written notice
by a Representative or a Person representing himself to be a holder of Senior Debt (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Debt. In the event that the Trustee
determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article 13, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article 13, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

Section 13.06. No Impairment of Conversion Right. For the purposes of this Article 13 only, the
settlement of the Company’s Conversion Obligation pursuant to this Indenture (including, without limitation, the Cash Settlement of any applicable Early Conversion Payment and the payment of cash in lieu of fractional shares upon settlement of
the Base Conversion Amount, in each case subject to the provisions of Section 14.02(a)) shall not be deemed to constitute a payment or distribution on account of the principal or interest on the Notes or on account of the repurchase or other
acquisition of Notes. 
 Nothing contained in this Article 13 or elsewhere in this Indenture or in the Notes is intended to or shall impair,
as among the Company, its creditors other than holders of Senior Debt and the Holders, the right, which is absolute and unconditional, of the Holder of any Note to convert such Note in accordance with Article 14. 

Section 13.07. Senior Debt Entitled to Rely. The holders of Senior Debt shall have the right to rely
upon this Article 13, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. 

  
 54 








 Section 13.08. Reinstatement. To the extent the payment
of or distribution in respect of any Senior Debt (whether by or on behalf of the Company as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to
any receiver, trustee in bankruptcy, liquidating trustee, agent or similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, such
receiver, trustee in bankruptcy, liquidating trustee, agent or similar Person, the Senior Debt or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred. 

Section 13.09. Action by Holders of Senior Debt. The holders of the Senior Debt may, at any time and
from time to time, without the consent of or notice to the Trustee or the Holders, without incurring responsibility to the Holders and without impairing or releasing the subordination provided in this Indenture or the obligations of the Holders
hereunder to the holders of the Senior Debt, do any one or more of the following: 
 (i) change the manner, place or terms of
payment or extend the time of payment of, or renew or alter, the Senior Debt or any instrument evidencing the same or any agreement under which any Senior Debt is outstanding or secured; 

(ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise secured; 

(iii) release any Person liable in any manner for the collection of Senior Debt; 

(iv) exercise or refrain from exercising any rights against the Company or any other Person; and 

(v) take any other action in the reasonable business judgment of the holders of Senior Debt. 

Section 13.10. Limitation on Incurring Senior Subordinated Indebtedness. The Company will not,
directly or indirectly, incur, or suffer to exist, any indebtedness that by its terms would expressly rank senior in right of payment to the Notes and subordinate in right of payment to any of its Senior Debt. 

For the purposes of this Section 13.10, “incur” means, with respect to any indebtedness or other obligation of any Person, to
create, issue, incur (including by conversion, exchange or otherwise), assume, guarantee or otherwise become liable in respect of such indebtedness or other obligation or the recording, as required pursuant to GAAP or otherwise, of any such
indebtedness or other obligation on the balance sheet of such Person (and “incurrence,” “incurred” and “incurring” shall have meanings correlative to the foregoing). Indebtedness of


  
 55 








 
any Person or any of its subsidiaries acquired by the Company or existing at the time such Person becomes a Subsidiary of the Company (or is merged into or consolidated with the Company or any
Subsidiary of the Company), whether or not such indebtedness was incurred in connection with, as a result of, or in contemplation of, such Person becoming a Subsidiary of the Company (or being merged into or consolidated with the Company or any
Subsidiary of the Company), shall be deemed incurred at the time any such Person becomes a Subsidiary or merges into or consolidates with the Company or any Subsidiary of the Company. 

Section 13.11. Trustee Not Fiduciary for Holders of Senior Debt. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of Senior Debt and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Notes or to the Company or to any other person cash, property or
securities to which any holders of Senior Debt shall be entitled by virtue of this Article 13 or otherwise. With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are
specifically set forth in this Article 13 and no implied covenants or obligations with respect to holders of Senior Debt shall be read into this Indenture against the Trustee. 

ARTICLE 14

CONVERSION OF NOTES 

Section 14.01. Conversion Privilege. 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 a multiple thereof) of such Note at any time prior to the close of
business on the Scheduled Trading Day immediately preceding the Maturity Date at an initial conversion rate of [            ] 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 the settlement provisions of Section 14.02, the “Conversion Obligation”). 

Section 14.02. Conversion Procedure; Settlement Upon Conversion. 

(a) Upon conversion of any Note, the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of Notes being
converted, (x) a number of shares of Common Stock equal to the Conversion Rate, together with a cash payment, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (the
“Base Conversion Amount”) and (y) for conversions where an Early Conversion Payment is due upon conversion, the Early Conversion Settlement Amount, on the third Scheduled Trading Day immediately following the relevant
Conversion Date, unless (i) such Conversion Date occurs following the Regular Record Date immediately preceding the Maturity Date, in which case the Company shall make such delivery (and payment, if applicable) of the Base Conversion Amount on
the Maturity Date, (ii) a Make-Whole Adjustment Event described in clause (b) of the definition of Fundamental Change occurs in which the Reference Property following such Make-Whole Adjustment Event is composed entirely of cash, in which
case the 

  
 56 








 
Company shall make payment of the Make-Whole Cash Settlement Amount on the tenth Business Day following the Conversion Date or (iii) the Company elects Physical Settlement of the Early
Conversion Payment, in which case the Company shall deliver the Base Conversion Amount and the Early Conversion Settlement Amount on the third Scheduled Trading Day following the last Trading Day of the applicable Averaging Period. In respect of any
conversions for which an Early Conversion Payment is due, the Company, through the Trustee, shall deliver a notice (the “Settlement Notice”) to converting Holders electing Cash Settlement or Physical Settlement of the Early Conversion
Settlement Amount no later than the close of business on the Trading Day immediately following the relevant Conversion Date. If the Company does not notify such Holders prior to the deadline set forth in the immediately preceding sentence, the
Company shall be deemed to have elected Physical Settlement in respect of such Early Conversion Settlement Amount. 
 (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 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 not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03. 

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

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that the Holder has complied with the requirements set forth in subsection (b) above. 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 

  
 57 








 
payment of a sum sufficient to cover any transfer tax or other 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 the shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be
issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s
name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence. 

(f) Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares 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 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 upon conversion rather than cancelled, extinguished or forfeited. Notwithstanding the
foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding
Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be
accompanied by funds equal to the amount of interest payable on the principal amount of the Notes so converted on such Interest Payment Date; provided, however, that no such payment shall be required (1) 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 succeeding the corresponding Interest Payment Date; (2) to the extent of any Defaulted Amounts, if any Defaulted Amounts
exist at the time of conversion with respect to such Note; or (3) for conversions following the close of business on the Regular Record Date immediately preceding the Maturity Date. The Company shall not be required to convert Notes not
accompanied by funds equal to the amount of interest payable on such Notes required by this subsection (h). 
 (i) The Person in whose name
the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date. Upon a conversion of Notes, such Person shall no longer
be a Holder of such Notes surrendered for conversion. 

  
 58 








 (j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes
(including upon Physical Settlement of any applicable Early Conversion Payment) and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion with respect to each of the Base Conversion Amount and, if
applicable, the Early Conversion Settlement Amount based on the Closing Sale Price of the Common Stock on the relevant Conversion Date. For purposes of determining cash payments in lieu of fractional shares pursuant to this subjection (j), the
principal amount of Notes being converted by the relevant Holder shall be aggregated. 
 Section 14.03.
Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Adjustment Events. (a) If the “Effective Date” (as defined below) of a Make-Whole Adjustment Event occurs prior to the Maturity
Date and a Holder elects to convert its Notes in connection with such Make-Whole Adjustment Event, 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 Adjustment Event if the relevant Notice
of Conversion is received by the Conversion Agent beginning with, and including, the Effective Date of the Make-Whole Adjustment Event up to, and including, the Scheduled Trading Day immediately prior to the related Fundamental Change Repurchase
Date (or, in the case of a Make-Whole Adjustment Event that would have been a Fundamental Change but for the exception provided by subclause (B) in clause (b) of the definition thereof, the 30th Scheduled Trading Day immediately following
the Effective Date of such Make-Whole Adjustment Event). 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole
Adjustment Event pursuant to Section 14.01, the Company shall deliver shares of Common Stock, including the Additional Shares, in accordance with Section 14.02; provided, however, that if, at the effective time of a
Make-Whole Adjustment Event described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Adjustment Event is composed entirely of cash, for any conversion of Notes following the Effective
Date of such Make-Whole Adjustment Event, the Conversion Obligation shall be calculated based solely on the Share 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 Share Price (the “Make-Whole Cash Settlement Amount”). The Company shall notify the Holders of Notes and the Trustee of the Effective Date
of any Make-Whole Adjustment Event and issue a press release describing the Make-Whole Adjustment Event and the Holders’ rights to any Additional Shares no later than such Effective Date (the “Make-Whole Adjustment Event Company
Notice”). 
 (c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by
reference to the table below, based on the date on which the Make-Whole Adjustment Event occurs or becomes effective (the “Effective Date”) and the price 

  
 59 








 
(the “Share Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Adjustment Event. If the holders of the Common Stock receive only cash in exchange
for their Common Stock in a Make-Whole Adjustment Event described in clause (b) of the definition of Fundamental Change, the Share Price shall be the cash amount paid per share. Otherwise, the Share Price shall be the average of the Closing
Sale Prices of the Common Stock over the ten Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date. The Board of Directors shall make appropriate adjustments to the Share Price, in its good faith
determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, during such ten consecutive Trading Day period.

 (d) The Share Prices set forth in the first row of the table below (i.e. column headers) shall be adjusted as of any date on which the
Conversion Rate of the Notes is otherwise adjusted. The adjusted Share Prices shall equal the Share 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 Share 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 as the
Conversion Rate as set forth in Section 14.04. 
 (e) The following table sets forth the Share Price paid (or deemed paid) per share of the
Common Stock and the number of Additional Shares per $1,000 principal amount of Notes pursuant to this Section 14.03 by which the Conversion rate shall be increased for each Share Price and Effective Date set forth below: 

 
  

																											
	 	  	Share Price
	Effective Date	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]	  	$[    ]

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

(i) if the Share Price is between two Share Prices in the table above or the Effective Date is between two Effective Dates in
the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Share Prices and the earlier and later Effective Dates, as applicable, based
on a 365-day year; 
 (ii) if the Share Price is greater than
$[            ] per share (subject to adjustment in the same manner as the Share Prices set forth in the column headers of the table above pursuant to subsection (d) above), the
Conversion Rate shall not be adjusted; and 

  
 60 








 (iii) if the Share Price is less than
$[            ] per share (subject to adjustment in the same manner as the Share Prices set forth in the column headers of the table above pursuant to subsection (d) above the
Conversion Rate shall not be adjusted. 
 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon
conversion exceed [            ] per $1,000 principal amount of Notes, 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 Adjustment Event. 
 Section 14.04. Adjustment of Conversion Rate. The Conversion Rate
shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or
share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes, as if
they held a number of shares of Common Stock equal to (i) the Conversion Rate, multiplied by (ii) the principal amount of Notes held by such Holder, divided by $1,000. 

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





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record 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 the case may be;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the effective date of such share split or share combination, as
the case may be;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split
or share combination, as the case may be; and


  
 61 









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

 Any adjustment made under this Section 14.04(a) shall become effective immediately after the close of business on the
Record Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this
Section 14.04(a) is declared that results in an adjustment to the Conversion Rate under this Section 14.04(a) but is not so paid or made, or the outstanding shares of Common Stock are not split or combined, as the case may be, the
Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such split or combination, to the Conversion Rate that would then be in effect if such
dividend or distribution or share split or share combination had not been declared or announced. 
 (b) If the Company distributes to all or
substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days from the declaration date of such distribution, to subscribe for or purchase shares of the Common Stock at a
price per share that is less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration date of such distribution, the
Conversion Rate shall be increased based on the following formula: 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such distribution;
			
	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 Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the declaration date for such distribution.


  
 62 








 Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options
or warrants are distributed and shall become effective immediately after the close of business on the Record Date for such distribution. 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 distribution 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 distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Record Date for such distribution had not been
fixed. 
 For purposes of this Section 14.04(b), in determining whether any rights, options or warrants entitle the holders to
subscribe for or purchase shares of the Common Stock at less than such average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the declaration
date for such distribution, 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, with 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 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, or distributions (including share splits) as to which an adjustment was effected pursuant to Section 14.04(a) or (b), (ii) Spin-Offs to which the provisions set forth below in this Section 14.04(c) shall
apply and (iii) dividends or distributions paid in cash as to which an adjustment was effected pursuant to Section 14.04(d) (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or
warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 

 
 



 
 where, 
  

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


  
 63 









					
	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 Record Date for such distribution.

 Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the close of
business on the Record 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, upon
conversion, in respect of each $1,000 principal amount thereof, the amount 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 Record 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 Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Record Date
for such distribution. 
 With respect to an adjustment pursuant to this Section 14.04(c) where there has been a 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, which Capital Stock or similar equity interest will be quoted or listed for trading on
a U.S. national securities exchange after its distribution (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV	  	=	  	the average of the Closing 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 Closing 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 immediately following, and including, the Ex-Dividend Date of the
Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.


  
 64 








 The adjustment to the Conversion Rate under the preceding paragraph shall occur at the close of business on the
last Trading Day of the Valuation Period; provided that in respect of any conversion during the Valuation Period, references in the portion of this Section 14.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced
with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate. 

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 its 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 Record 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 (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), any dividend or distribution to which this Section 14.04(c) is applicable that also includes one or both of: 

  
 65 








 (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 (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 Record Date of the Clause A Distribution and the Clause B Distribution shall be deemed to be
the Record 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 close of business on the Record Date
for such distribution or immediately after the open of business on the effective date of such share split or share combination, as the case may be” within the meaning of Section 14.04(a) or “outstanding immediately prior to the close
of business on the Record Date for such distribution” within the meaning of Section 14.04(b). 
 (d) If the Company pays any cash
dividend or distribution to all or substantially all holders of the Common Stock, the Conversion Rate shall be increased based on the following formula: 
  





 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution;
			
	CR’	  	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution;
			
	SP0	  	=	  	the average of the Closing 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 dividend or distribution;
and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of its Common Stock.


  
 66 








 Any increase pursuant to this Section 14.04(d) shall become effective immediately after the close of
business on the Record Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or
distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, upon conversion, for each $1,000 principal amount of Notes, 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 Record Date for such cash dividend or distribution. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock, to the
extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period immediately following, 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 “Expiration Date”), the Conversion Rate shall be increased based on the following
formula: 
  
 



 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date;
			
	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 Expiration Date;
			
	FMV	  	=	  	the aggregate value, on the Expiration Date, of all cash and the fair market value (as determined by the Board of Directors) of any other consideration paid or payable for shares of Common Stock validly tendered or exchanged as of
the Expiration Date;
			
	OS’	  	=	  	the number of shares of Common Stock outstanding immediately after the time (the “Expiration Time”) that the tender or exchange offer expires (after giving effect to such tender offer or exchange offer);
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the Expiration Time (prior to giving effect to such tender offer or exchange offer); and


  
 67 









					
	SP’	  	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

 The adjustment 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 Expiration Date; provided that in respect of any conversion within the 10 Trading Days immediately following, and including, the Expiration Date, references in
this Section 14.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Expiration Date and the Conversion Date in determining the Conversion Rate. 

(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 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) If the application of the formulas in clauses (a), (b), (c),
(d) and (e) of this Section 14.04 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse share split or share combination). In no event will the
Company adjust the Conversion Rate (or take any action that would result in an adjustment to the Conversion Rate) to the extent that the adjustment would reduce the Conversion Price below the par value per share of its Common Stock. 

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

(i) 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, the Company from time to time may (but is not required to) 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, so long as the increase is irrevocable during such period. In addition, 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 (or rights to acquire shares) of Common Stock or similar event to the extent permitted by applicable law. Whenever the Conversion Rate is increased pursuant to either of
the preceding two sentences, the Company shall send to the Holder of each 

  
 68 








 
Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the
increased Conversion Rate and the period during which it will be in effect. 
 (j) 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 the Company; 
 (iii) ordinary course repurchases of
Common Stock, including structured or derivative transactions; 
 (iv) pursuant to a stock repurchase program approved by the
Company’s Board of Directors (but, for the avoidance of doubt, excluding transactions described in Section 14.04(g) as to which an adjustment to the Conversion Rate has been made); 

(v) for any accrued and unpaid interest; 

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

(vii) 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; 

(k) 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 (1/10,000) of a share. 
 (l) The Company will not be required to make an adjustment in the Conversion Rate unless the
adjustment would require an increase or decrease of at least 1% of the Conversion Rate. However, the Company will carry forward any adjustment that is less than 1% of the Conversion Rate, take such carried–forward adjustments into account in
any subsequent adjustment, and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1%, on the Conversion Date for any affected Notes, unless such adjustment has already been made. 

(m) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if
not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the


  
 69 








 
Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the
last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on
which each adjustment becomes effective and shall send such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the
legality or validity of any such adjustment. 
 (n) For purposes of this Section 14.04, the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable
in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 14.05.
Adjustments of Prices. Whenever any provision of this Indenture requires the Company to calculate the Closing Sale Prices or the Share Price for purposes of a Make-Whole Adjustment Event over a span of multiple days, 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 Record Date of the event occurs, at any time during the
period when such Closing Sale Prices or Share Prices 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 that at the time of computation of such number of shares, all such Notes would be converted by a single Holder). 

Section 14.07. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock. 

(a) In the event of: 

(i) any reclassification of the Common Stock (other than changes resulting from a subdivision or combination), 

(ii) a consolidation, merger or combination or binding share exchange involving the Company or 

(iii) any sale or conveyance to a third party of all or substantially all of the consolidated assets of the Company and the
Company’s Subsidiaries. 
 in each case, in which holders of the outstanding Common Stock are entitled to stock, other securities or other property or
assets (including cash or any combination thereof) for their 

  
 70 








 
Common Stock (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 type 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 any 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(i) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, that at and after the effective time of the
Merger Event the number of shares of Common Stock otherwise deliverable upon conversion of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of
shares of Common Stock would have received in such Merger Event. 
 For purposes of this Section 14.07, if the Merger Event causes the
Common Stock to be converted into the right to receive more than a single type of consideration because the holders of the Common Stock have the right to elect the type of consideration they receive, then (i) the Reference Property into which
the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, 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. The Company shall notify Holders and the Trustee of such weighted average as soon as
practicable after such determination is made. 
 Such supplemental indenture described in the second immediately preceding paragraph shall
provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 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) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of
this Section 14.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property
after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly send notice thereof to all Holders. The Company shall cause notice of the execution of such
supplemental indenture to be sent to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such
supplemental indenture. 

  
 71 








 (c) The above provisions of this Section shall similarly apply to successive Merger Events. 

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 and not subject to further call or assessment 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 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 Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to
Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any
adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. 

  
 72 








 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 sent to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable
date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common
Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such 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. 

Section 14.11. Stockholder Rights Plans. If the Company adopts a stockholder rights plan providing
that each share of Common Stock issued upon conversion of the Notes, at any time prior to the distribution of separate certificates representing the rights, 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, then no adjustment to the
Conversion Rate shall be made as a result of the issuance of such rights, the distribution of separate certificates representing rights, the exercise or redemption of rights in accordance with any stockholder rights agreement, or the termination or
invalidation of such rights, and Holders shall receive the appropriate number of rights, if any, under the stockholder rights plan upon conversion. If at any time prior to conversion, however, the rights have separated from the shares of Common
Stock in accordance with the provisions of the applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Notes, the Conversion Rate shall be adjusted
at the time of separation as if the Company distributed to all or substantially all holders of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, other assets or property or rights, options or warrants to acquire its
Capital Stock or other 

  
 73 








 
securities as provided in Section 14.04(c) (and shall be further adjusted consistent with such Section 14.04(c) in the event of certain events affecting such rights following any
separation from the Common Stock), 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. Intentionally Omitted.

 Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a
Fundamental Change occurs prior to the Maturity Date, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof that
is equal to $1,000 or a 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 45 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 15.02 shall be made, at the option of the Holder thereof, upon: 

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase
Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are 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 on or before the close of business on the
Business Day immediately preceding the Fundamental Change Repurchase Date (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes,
in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 

  
 74 








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

 (i) the portion of the principal amount of Notes to be repurchased, which must in multiples of $1,000; 

(ii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;
and 
 (iii) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 

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 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental
Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.03. 
 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) Within 10 calendar days of 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. Such notice shall be by first class mail or, in the case of Global Notes, 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:

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;

converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; 

(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 15.02. 
 At the Company’s written request,
the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any 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 15.03. Withdrawal of Fundamental Change Repurchase Notice. A Fundamental Change Repurchase
Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 15.03 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, which shall be in multiples of $1,000, 

  
 76 








 (ii) if Physical Notes have been issued, the certificate numbers of the Notes 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 multiples of $1,000; 
 provided,
however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary. 
 
Section 15.04. Deposit of Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside,
segregate and hold in trust as provided in Section 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be 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 with respect to such Note (provided the Holder has satisfied the conditions in
Section 15.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 15.02 by sending checks for
the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account
of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to Notes that have been properly surrendered for repurchase and not
validly withdrawn, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying
Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price). 

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.02, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 

  
 77

Repurchase of Notes. In connection with any repurchase offer, the Company will, if required, comply with:

13e-4, Rule 14e-1 under the Exchange Act; and 
 (b) any other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of such Notes as a result of a Fundamental Change,

including under Section 2.04, 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 time terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall send notice of such
appointment to all Holders as the names and addresses of such Holders appear on the Note Register. 
 The Company agrees to pay to the
authenticating agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines such agent’s fees to be unreasonable. 

The provisions of Section 7.02, Section 7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be applicable
to any authenticating agent. 
 If an authenticating agent is appointed pursuant to this Section, the Notes may have endorsed thereon, in
addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 

                          
                          , 

as Authenticating Agent, certifies that this is one of the Notes described in the within-named Indenture.

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

Trustee 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 written request of that Holder
at the sole cost and expense of the Company.

Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 FORM OF REVERSE OF NOTE 

Solazyme, Inc. 

[            ]% Convertible Senior Subordinated Note due 2019 

This Note is one of a duly authorized issue of Notes of the Company, designated as its
[            ]% Convertible Senior Subordinated Notes due 2019 (the “Notes”), limited to the aggregate principal amount of
$[            ] (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the Underwriter pursuant to the exercise of its option to
purchase additional Notes as set forth in the Underwriting Agreement) all issued or to be issued under and pursuant to an Indenture dated as of [            ], 2014 (the
“Indenture”), between the Company and Wells Fargo Bank, National Association (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. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, and
interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to
the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will
make all payments and deliveries in respect of the Fundamental Change Repurchase Price 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 (but subject to Article 13 of the Indenture) shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case

 The Notes are issuable in registered form without coupons in denominations of $1,000 principal
amount and multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of
other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the
name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange. 

The Notes are not subject to redemption through the operation of any sinking fund or otherwise. 

To the extent provided in the Indenture, this Note and all Notes are subordinated to Senior Debt. To the extent provided in the Indenture,
Senior Debt must be paid in full before the Notes may be paid. The Company agrees, and each Holder by accepting a Note agrees, to the subordination provisions contained in the Indenture and authorizes the Trustee to give it effect and appoints the
Trustee as attorney-in-fact for such purpose. 
 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 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 Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or
a multiple thereof, into shares of Common Stock at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. For conversions where the Conversion Date occurs prior to
[            ] (other than conversions deemed in connection with a Make-Whole Adjustment Event), the Company shall also pay or deliver the Early Cash Settlement Amount as set forth
in the Indenture. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined.
