Any Global Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not

 Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends

rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special
limitations or restrictions to which any particular Notes are subject. 
 Each Global Note shall represent such principal
amount of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding
Notes represented thereby may from time to time be increased or reduced to reflect PIK Payments, repurchases, cancellations, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase

than $2,000,000 either by check mailed to each Holder or, upon application by such a Holder to the Note Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within
the United States, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or
its nominee. 
 If the Company elects to pay the Interest Amount in shares of Common Stock, the number of such shares to be
issued shall be the number determined by dividing (x) the Interest Amount due or to be converted (as applicable), by (y) the Last Reported Sale Price as of the date on which the Interest Amount was calculated. Such shares shall be issued
and delivered on the applicable Interest Payment Date. In order to pay the Interest Amount in shares of Common Stock, the Company shall deliver a notice (an “Interest Payment Notice”) to the Trustee no later than the 15th calendar
day immediately prior to the Regular Record Date preceding such Interest Payment Date, which notice shall state the total Interest Amount to be paid on the Interest Payment Date and the number of shares of Common Stock to be issued in satisfaction
thereof. The Trustee, on behalf of the Company, shall promptly upon receipt of the Interest Payment Notice, and in no event later than the 10th calendar day immediately prior to the Regular Record Date preceding such Interest Payment Date, deliver a
corresponding notice prepared by the Company (which may be the same as the Interest Payment Notice) to the Holders.

 (c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder
on the relevant payment date but shall accrue interest per annum at the then-applicable rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and
such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or
their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the

the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date
of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such
Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly
notify the Trustee in writing of such special record date at least five (5) Business Days before such notice is to be sent to the Holders, and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Amounts and the special record date therefor to be sent to each Holder not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor
having been so sent, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to
the following clause (ii) of this Section 2.03(c). 
 (ii) The Company may make payment of any
Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such
exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so
signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer
of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such person
was not such an Officer. 
 Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer;
Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the
“Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable

 16 













 
Company Order, 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 Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and
duly executed, by the Holder thereof or its 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

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 Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The
transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the
restrictions on transfer set forth herein) and the procedures of the Depositary therefor. 
 (c) Notwithstanding any other
provisions of this Indenture, a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by
the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately
succeeding paragraph. 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially
appoints The Depository Trust Company to act as Depositary with respect to any Global Notes. Initially, each Global Note, if any, shall be issued to the Depositary, 

  
 17 













 
registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. 

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as
depositary for the Global Notes and a successor depositary is not appointed by the Company 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 Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal
amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a
portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled. 

Physical Notes issued in exchange for all or a part of the Global Note, pursuant to this Section 2.05(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, or, in the case of clause (iii) of the immediately preceding paragraph, the
relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

At such time as all interests in a Global Note have been converted, canceled, repurchased, redeemed 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, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of
such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note,
by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
 None of the
Company, the Trustee, the Paying Agent, the Conversion Agent or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership
interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Members of, or participants in, the Depositary shall have no rights under this Indenture with respect to any Global Note
held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for
all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any 

  
 18 













 
written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and Participants, the operation of customary practices governing the exercise
of the rights of a Holder of any Note. 
 (d) RESERVED. 

(e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of
the Company (or any Person who was an Affiliate of the Company at any time during the three months immediately preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless the resale is registered under the Securities
Act or conducted pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as defined under
Rule 144). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.08. 

(f) Notwithstanding anything contained herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible
for ascertaining whether any transfer complies with the registration provisions of or exemptions from the Securities Act, applicable state securities laws or other applicable federal or state laws. 

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 receipt of a Company Order the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not
contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the
Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case
of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon
the receipt of a Company Order and 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 payment or conversion shall furnish
to the Company, to the 

  
 19 













 
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, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee
or an authenticating agent appointed by the Trustee shall, upon 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 shall execute and deliver to the Trustee or such
authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to
Section 4.02 and the Trustee or such authenticating agent upon receipt of a Company Order 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 upon receipt of a Company Order, 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 cancelled Notes in accordance with its customary procedures. The Trustee shall deliver copies of such cancelled Notes to the Company, at the Company’s written request in a Company
Order. 

  
 20 













 Section 2.09. CUSIP Numbers. The Company in issuing the
Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the
Trustee in writing of any change in the “CUSIP” numbers. 
 Section 2.10. Additional Notes;
Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than
differences in the issue date, the issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that such additional Notes shall not reduce the amount of Exchange
Notes subject to Mandatory Conversion in Section 14.02. If any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number.
Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in
addition to those required by Section 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. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08, and upon receipt
of a Company Order, the Trustee and no one else shall cancel all Notes so surrendered and such Notes shall no longer be considered outstanding under this Indenture upon their surrender to the Trustee. 

Section 2.11. Issuance of PIK Notes; Payment of PIK Interest. If the Company determines to pay PIK
Interest in respect of the Notes, subject to any restrictions as set forth in the Form of Note in Exhibit A to this Indenture, the Company may elect to either increase the outstanding principal amount of the Notes or issue additional Notes (the
“PIK Notes”) under this Indenture having the same terms as the Notes (in each case, a “PIK Payment”). The Company shall make a PIK Payment (x) with respect to Notes represented by one or more Global
Notes, by increasing the principal amount of the outstanding Global Notes by an amount equal to the amount of PIK Interest due and payable (rounded up to the nearest whole U.S. dollar) and (y) with respect to Notes represented by Physical
Notes, by issuing PIK Notes in physical form in an amount equal to the amount of PIK Interest due and payable (rounded up to the nearest whole U.S. dollar). In order to pay PIK Interest pursuant to this Section 2.11, the Company shall deliver a
notice (a “PIK Notice”) to the Trustee no later than the 15th calendar day immediately prior to the Regular Record Date preceding such Interest Payment Date, which notice shall state the total amount of interest to be paid on the
Interest Payment Date and the amount of such interest to be paid as PIK Interest in accordance with the terms of the Notes. The Trustee, on behalf of the Company, shall promptly upon receipt of the PIK Notice, and in no event later than the 10th
calendar day immediately prior to the Regular Record Date preceding such Interest Payment 

  
 21 













 
Date, deliver a corresponding notice prepared by the Company (which may be the same as the PIK Notice) to the Holders. 

(b) Any PIK Notes issued in physical form will be issued with the designation “PIK Notes” on the face of such PIK
Notes, and shall be in minimum denominations of $1.00 and integral multiples thereof. Any PIK Notes ranking pari passu with the Notes may be created and issued from time to time by the Company without notice to or consent of the Holders and shall be
consolidated with and form a single class with the Notes and shall have the same terms as to status or otherwise as the Notes. All PIK Notes issued pursuant to a PIK Payment shall mature on the same Maturity Date as the originally issued Notes and
shall be governed by, and subject to the terms, provisions and conditions of, this Indenture and shall have the same rights and benefits as the Notes. Trustee shall authenticate and deliver such PIK Notes in physical form for original issuance to
the Holders thereof on the relevant Record Date, as shown by the records of the Note Register of such Holders. 
 (c)
Following an increase in the principal amount of the outstanding Global Notes as a result of a PIK Payment, the Global Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in
physical form will be distributed to Holders, dated as of the applicable Interest Payment Date and will bear interest on the principal amount of such PIK Note from and after the Interest Payment Date in respect of which such PIK Payment was made.

 ARTICLE 3 

SATISFACTION AND DISCHARGE 

Section 3.01. Satisfaction and Discharge. This Indenture and the Notes shall upon request of the Company
contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute such instruments reasonably requested by the Company, acknowledging satisfaction and discharge of this Indenture
and the Notes, when (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the
Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Fundamental Change Repurchase Date, upon
conversion or otherwise, cash or cash, shares of Common Stock or a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation, sufficient to pay all of the outstanding Notes and all other sums due and payable
under this Indenture by the Company; and the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of
this Indenture and the Notes 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. PIK Interest
shall be considered paid on the Interest Payment Date after any PIK Notice has been delivered to Holders. In respect of such Interest Payment Date and PIK Payment, the Trustee shall either receive (i) a Company Order, pursuant to
Section 2.11, to increase the balance of any Global Note to reflect such PIK Interest or (ii) a PIK Note duly executed by the Company together with a Company Order, pursuant to Section 2.11, requesting the authentication of such PIK
Note by the Trustee. 
 Section 4.02. Maintenance of Office or Agency. The Company will maintain in the
contiguous United States 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”). 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 and surrenders may be made or served at the Corporate Trust Office. 

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 contiguous United States 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 as the office or agency in the contiguous United States, where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion. The Corporate Trust Office
shall not be a place for service of legal process on the Company. 
 Section 4.03. Appointments to Fill Vacancies in
Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee
hereunder. 
 Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying
Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the
Fundamental Change Repurchase Price, if applicable) of, and 

  
 23 













 
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. The
Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Article 3). Upon the occurrence of any Event of Default under Section 6.01(j) or Section 6.01(k), the Trustee shall automatically be the Paying
Agent. 
 (c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the
purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this
Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all
further liability but only with respect to such sums or amounts. 
 (d) Subject to applicable abandoned property laws, any
money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on and the consideration
due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Repurchase Price, if applicable), interest or consideration due upon conversion has become due and payable shall be paid to
the Company on request of the Company contained in an Officers’ Certificate, or 

  
 24 













 
(if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease. 

Section 4.05. Existence. Subject to Article 11, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of any Significant Subsidiary. 

Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not
subject to Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the
meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes,
the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or
beneficial owner of such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may
be amended from time to time. 
 (b) The Company shall file with the Trustee, within 15 days after the same are required to
be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this
Section 4.06(b) at the time such documents are filed via the EDGAR system; provided, that the Trustee shall have no obligation to monitor whether such filings have been made or the content thereof. 

(c) Delivery of the reports and documents described in subsection (b) 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 Officers’ Certificate). 
 (d) If, at any time
during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is
required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K),
or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of
restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal
amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is 

  
 25 













 
continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time
during the three months immediately preceding). As used in this Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of the Exchange Act does not include
documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act. 

(e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed, the
Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months
immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the
Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP and the Notes are
freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities
laws or the terms of this Indenture or the Notes. 
 (f) Additional Interest will be payable in arrears on each Interest
Payment Date following accrual in the same manner as regular interest on the Notes. 
 (g) The Additional Interest that is
payable in accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03. 

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

Section 4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do
so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law 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, 2019) an Officers’ Certificate stating


  
 26 













 
whether 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, specifying each
such failure and the nature thereof. 
 In addition, the Company shall deliver to the Trustee, as soon as possible, and in
any event within 30 days after the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposing to take
in respect thereof. 
 Section 4.09. Further Instruments and Acts. Upon request of the Trustee, the
Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

(h) default by the Company or any Significant Subsidiary (or any group of Subsidiaries that, taken together, would constitute a

its foreign currency equivalent), individually or in the aggregate of the Company and/or any such Significant Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being
declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, and in the case of
clause (i) and (ii), such acceleration shall not have been rescinded or annulled or such failure to pay or default shall not have been cured or waived, or such indebtedness is not paid or discharged, as the case may be, within 30 days of
becoming due and payable; 
 (i) a final judgment or judgments for the payment of $15,000,000 (or its foreign currency

(j) the Company or any Significant Subsidiary (or any group of Subsidiaries that, taken together, would constitute a

 28

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; 

(k) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary (or any group

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 90 consecutive days; or 
 (l) the occurrence
of an Event of Default as such term is defined and as set forth in the Voluntary Indenture. 
 Section 6.02.
Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(j) or
Section 6.01(k) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding 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 on, all the
Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event of
Default specified in Section 6.01(j) or Section 6.01(k) with respect to the Company or any of its Significant Subsidiaries occurs, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall
automatically be immediately due and payable without any declaration or other act of the Holders or any act on the part of the Trustee. 

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the
Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to
the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time, plus one percent) 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 

  
 29 













 
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 (including PIK Notes), by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such
declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to
or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or
Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required
or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes. 

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

Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause
(a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest,
if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, plus one percent, and, in addition thereto, such further amount as shall be sufficient to cover any amounts


  
 30 













 
due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. 

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other
obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property
of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any
demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if
any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its
or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under
Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in
the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and
including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any
such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled
to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. 

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

  
 31 













 All rights of action and of asserting claims under this Indenture, or under
any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit
of the Holders of the Notes. 
 In any proceedings brought by the Trustee (and in any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such
proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings
shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in
every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the
Holders and the Trustee shall continue as though no such proceeding had been instituted. 
 Section 6.05.
Application of Monies Collected by Trustee. Any monies or property collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the
distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid: 

First, to the payment of all amounts due the Trustee under this Indenture; 

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

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

  
 32 













 
aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and 

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

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

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

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

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

Notwithstanding any other provision of this Indenture and any provision of any Note, each Holder shall have the right, which
is absolute and unconditional, to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the
consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or


  
 33 













 
delivery, as the case may be, and such rights shall not be impaired without the consent of such Holders. 

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 of the aggregate principal amount of the Notes at the time outstanding (including any PIK Notes) determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or
with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights
of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such directions are unduly prejudicial to such Holder) or that would involve the Trustee in personal liability, unless the
Trustee is offered indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction; provided, however, that the Trustee may take any other action
deemed necessary by the Trustee that is not inconsistent with such direction. 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 pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in
respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be
restored to their former positions and rights 

  
 34 













 
hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall
have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent
or other Default or Event of Default or impair any right consequent thereon. 
 Section 6.10. Notice of
Defaults. The Trustee shall, within 90 days after it obtains knowledge of the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Holders 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 a Responsible Officer
of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 

Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by
its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by
it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party
litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding 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, if applicable) on or after the due date
expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 14. 

ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of
Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In the event an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such
person’s own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders
unless such Holders 

  
 35 













 
have offered to the Trustee indemnity or security satisfactory to it in its reasonable discretion against any loss, liability or expense 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: 

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this
Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee;
and 
 (ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such
certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture
(but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (b) the
Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 

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

(d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of,
or affording protection to, the Trustee shall be subject to the provisions of this Section; 
 (e) the Trustee shall not be
liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any
co-Note Registrar with respect to the Notes; 

  
 36 













 (f) if any party fails to deliver a notice relating to an event the fact of
which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a Responsible Officer of the Trustee had
actual knowledge of such event; 
 (g) 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 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, Bid Solicitation
Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer agent and
to each agent, custodian, and other Person employed to act hereunder. 
 None of the provisions contained in this Indenture
shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. The Trustee will be under no obligation to exercise
any of its rights and powers under this Indenture at the request or direction of the Holders unless such Holder has offered to the Trustee security or indemnity satisfactory to it in its reasonable discretion against any loss, liability or expense.

 (a) the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement,

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 

  
 37 













 
discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it
shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation; 

(e) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or
through a co-trustee, 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;

reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 

(h) the Trustee shall not be responsible for monitoring the performance of other persons or for the failure of others to
perform their duties; 
 (i) the Holders will not direct the Trustee to take action contrary to this Indenture, the Notes or

and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as
so authorized in any such certificate previously delivered and not superseded; and 
 (k) the Trustee shall not be required
to give any bond or surety in respect of the execution of the trusts and powers under this Indenture. 
 In no event shall
the Trustee be liable for any special, punitive, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action. The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of
Default or (2) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or actually received by a Responsible Officer at the Corporate Trust Office of the Trustee from the Company, a Paying Agent,
any Holder or any agent of any Holder, referencing this Indenture and stating that it is a “notice of default”. 

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 

  
 38 













 
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, Bid Solicitation Agent or
Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would
have if it were not the Trustee, Paying Agent, Conversion Agent, Bid Solicitation Agent or Note Registrar. 

Section 7.05. Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied
as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability
for interest on any money received by it hereunder except as may be agreed from time to time by the Company and the Trustee. The Trustee shall not be obligated to take possession of any Common Stock, whether upon conversion, in respect of Interest
Amounts, or in connection with any discharge of this Indenture pursuant to Article 3 hereof, but shall satisfy its obligation as Conversion Agent or Paying Agent by working through the stock transfer agent of the Company from time to time as
directed by the Company. 
 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, 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
and including reasonable attorneys’ fees in connection with enforcement of its rights to indemnity herein) except any such expense, disbursement or advance as shall have been caused by its gross negligence, or willful misconduct as determined
by a final non-appealable order of a court of competent jurisdiction. 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, fee, cost, loss, tax, claim, action or expense incurred without gross negligence, or willful misconduct as
determined by a final non-appealable order of a court of competent jurisdiction 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 third-party claims and claims involving the Company, and including the costs and expenses of defending
themselves against any claim of liability in the premises. The obligations of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be
secured by a senior lien 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 or other property, funds held in trust herewith for the benefit of
the Holders of particular Notes. The Trustee’s right to receive 

  
 39 













 
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 of the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The
indemnification provided in this Section 7.06 shall extend to the officers, directors, agents and employees of the Trustee. 

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(j) or Section 6.01(k) occurs, the expenses and the compensation for the services are intended to constitute expenses of
administration under any bankruptcy, insolvency or similar laws. 
 Section 7.07. Officers’
Certificate and Opinion of Counsel 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 or willful misconduct on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers’ Certificate and Opinion of Counsel delivered to the Trustee, and such Officers’ Certificate and Opinion of Counsel, in the absence of gross negligence or willful misconduct
on the part of the Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 

Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, 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 delivering notice thereof to the Holders. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60
days after the giving of such notice of resignation to the Holders, the resigning Trustee may at the expense of the Company, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the
appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, subject to the provisions of Section 6.11, on behalf of himself or herself
and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it 

  
 40 













 
may deem proper and prescribe, appoint a successor trustee, and the Company shall bear the expense associated with such appointment. 

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

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall
fail to resign after written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee
shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, 
 then, in either case, the Company may by a Board Resolution remove the
Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to
the provisions of Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

 (c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding (including any PIK
Notes), as determined in accordance with Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination
the Company objects thereto, in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a successor
trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the
provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 

Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless,
on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such
successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such
successor trustee all such rights and powers. 

  
 41 













 
Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for
funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such
successor trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of appointment by a
successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee
hereunder to the Holders. If the Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be delivered 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 to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be
less than three Business Days after the date any officer that the Company has 

  
 42 













 
indicated to the Trustee should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking
any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 

ARTICLE 8 

CONCERNING THE HOLDERS 

Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified
percentage of the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any
such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, or
(b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a
meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for
determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 

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 (including any Fundamental Change Repurchase
Price) 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. The sole registered holder of a Global Note shall be the Depositary or its nominee. All such payments or deliveries so made to any Holder for the time being, or upon its order, shall be
valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this
Indenture or the Notes following an Event of Default, any holder of a beneficial interest in a Global Note may directly enforce against the Company, without the 

  
 43 













 
consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note in certificated
form in accordance with the provisions of this Indenture. 
 Section 8.04. Company-Owned Notes
Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any
Subsidiary thereof or by any Affiliate of the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or
an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01, the
Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 

Section 8.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the
evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note
that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02,
revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in
exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer
thereof.

authorized representatives or have, before or after the meeting, waived notice. 
 Section 9.03. Call of Meetings by

 45 













 
Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent

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

 Upon the written request of the Company, the Trustee is hereby authorized to
join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into
any supplemental indenture that affects the Trustee’s own rights, duties, liabilities or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 10.01 may be executed by the Company and the
Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 

Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as
provided in Article 8) of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding (including any PIK Notes, and determined in accordance with Article 8 and including, without limitation, consents obtained
in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors, at the Company’s expense, may from time to time and at any time enter into an indenture or
indentures supplemental hereto with the Trustee for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as

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

Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture
pursuant to the provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights,

limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject
in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 10.04. Notation on Notes. Notes authenticated and delivered after the execution of any
supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Company as to any matter provided for in such supplemental indenture. If the Company or the Trustee

executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

 Section 10.05. Evidence of Compliance of Supplemental Indenture to Be Furnished Trustee. In

 ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

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

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a
corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations
of the Company under the Notes and this Indenture; 
 (b) the Company delivers an Officer’s Certificate and Opinion of
Counsel to the Trustee stating that such consolidation, merger or sale, conveyance, transfer or lease and any supplemental indenture comply with this Indenture and that all conditions precedent set forth in this Indenture have been complied with;
and 
 (c) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be
continuing under this Indenture. 
 For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all
or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the
properties and assets of the Company on a 

  
 49 













 
consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person. 

Section 11.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale,
conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the
Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company,
such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been
named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall
deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to
be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person
named as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and liquidated at any time thereafter and,
except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes. 

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not
in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 11.03. Opinion of
Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any
such consolidation, merger, sale, conveyance, transfer or lease, as the case may be, and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with the provisions of
this Article 11, and which Opinion of Counsel shall state that the Notes and such supplemental indenture are valid and binding obligations of the Successor Company.

in any supplemental indenture or in any Note, nor because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or
future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or

ARTICLE 14 

CONVERSION OF NOTES 

Section 14.01. Voluntary Conversion. (a) Subject to and upon compliance with the provisions of this
Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion of such Note (i) subject to satisfaction of the conditions described in Section 14.01(b), at any time prior to the close of
business on the Business Day immediately preceding January 1, 2024 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), on or after
January 1, 2024 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 0.12103 (subject to adjustment as provided in this Article 14, the
“Applicable Conversion Rate”) per $1.00 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.03, the “Conversion Obligation”), equivalent to the Conversion
Price. 
 (b) (i) Prior to the close of business on the Business Day immediately preceding
January 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at any time during the five consecutive Business Day period immediately following any twenty consecutive Trading Day period (the “Measurement
Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of
the product of the Last Reported Sale Price of the Common Stock on each such Trading Day and the Applicable Conversion Rate on each such Trading Day (the “Trading Price Condition”). The Trading Prices shall be determined by the Bid
Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three


  
 51 













 
independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation
Agent shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination in writing (and provided the Bid Solicitation Agent of the names and contact information for such
dealers) and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product
of the Last Reported Sale Price of the Common Stock on such Trading Day and the Applicable Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent in writing to determine the Trading Price per $1,000
principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common
Stock and the Applicable Conversion Rate. 
 If the Company does not instruct the Bid Solicitation Agent to determine the
Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent in writing to obtain bids and the Bid Solicitation Agent fails to make such
determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate on each Trading Day
of such failure. 
 If on any date of determination of the Trading Price (i) the Bid Solicitation Agent cannot
reasonably obtain at least one bid for $2,000,000 principal amount of Notes from an independent nationally recognized securities dealer, (ii) if the Company has failed to request the Bid Solicitation Agent to obtain bids when required or
(iii) if the Company requested the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent has failed to obtain such bids, then, in each case, the Notes shall be convertible under the Trading Price Condition for the next 5
consecutive Business Days following such date of determination. The Company shall determine the Trading Price of the Notes and whether the Trading Price Condition has been met, and, if so, the Company shall so notify the Holders, the Trustee, the
Conversion Agent and the Bid Solicitation Agent. 
 If, at any time after the Trading Price Condition has been met, the
Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Closing Sale Price of the Common Stock and the applicable Applicable Conversion Rate for such date, the Company shall so notify the Holders,
the Trustee, the Conversion Agent and the Bid Solicitation Agent. 
 If the Trading Price condition set forth above has been
met, the Company shall so notify the Holders in writing, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount
of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion 

  
 52 













 
Rate for such date, the Company shall so notify the Holders of the Notes in writing, the Trustee and the Conversion Agent (if other than the Trustee). 

(ii) If, prior to the close of business on the Business Day immediately preceding January 1, 2024, the
Company elects to: 
 (A) issue to all or substantially all holders of the Common Stock any rights, options
or warrants (other than pursuant to a stockholder rights plan in respect of which the stockholder rights have not separated from the shares of Common Stock) entitling them, for a period of not more than 45 calendar days after the announcement date
of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the
Trading Day immediately preceding the date of announcement of such issuance; or 
 (B) distribute cash, debt
securities (or other evidence of indebtedness) or other assets or securities (including, for the avoidance of doubt, any rights, options or warrants that are not described in clause (i) above, but excluding dividends or distributions described
in Section 14.04(c), which distribution has a per share value exceeding 10% of the Closing Sale Price of Common Stock as of the Trading Day immediately preceding the declaration date for such distribution, 

then, in either case, the Company shall notify in writing all Holders of the Notes, the Trustee and the Conversion Agent (if
other than the Trustee) either (x) at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution or (y) at least 10 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution; provided that, if the Company provides such notice in accordance with this clause (y) but not in accordance with the immediately preceding clause (x),
notwithstanding anything to the contrary in Section 14.02 or any other provision of this Indenture, the Company shall be required to settle all conversions of Notes with a Conversion Date occurring during the period from, and including, the
date of such notice to, and including, the Ex-Dividend Date for such distribution using Physical Settlement and the Company shall so notify the Holders in such notice. Once the Company has given such notice,
Holders may surrender their Notes for conversion at any time until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date and the Company’s announcement that
such issuance or distribution will not take place. A Holder may not convert any of its Notes under this subsection (b)(ii) if the Company provides that Holders of the Notes shall participate, at the same time and upon the same terms as holders of
Common Stock and as a result of holding the Notes, in the relevant distribution described above without having to convert their Notes as if they held a number of shares of Common Stock equal to the Applicable Conversion Rate on the record date for
the distribution multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 

(iii) If (A) a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental
Change occurs prior to the close of business on the Business 

  
 53 













 
Day immediately preceding January 1, 2024, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or (B) the Company
is a party to a consolidation, merger, binding share exchange, or sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of its assets that occurs prior to the close of business on the Business Day immediately
preceding January 1, 2024, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, then all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after
the date that is 35 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the earlier of (x) the Business Day after the Company gives notice of such transaction and (y) the actual effective date
of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the close of business on the related Fundamental Change Repurchase Date. The Company
shall give notice to Holders, the Trustee and the Conversion Agent (if other than the Trustee) (x) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 35 Scheduled Trading Days
prior to the anticipated effective date of such transaction or (y) if the Company does not have knowledge of such transaction at least 35 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business
Day of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction; provided that, notwithstanding the foregoing, in no event shall
the Company be required to provide such notice to the Holders before the earlier of such time as the Company or its affiliates (x) have publicly disclosed or acknowledged the circumstances giving rise to such transaction or event and
(y) are required to publicly disclose under applicable law or the rules of any securities exchange on which the Common Stock is then listed or admitted for trading the circumstances giving rise to such transaction or event. 

(iv) Notwithstanding anything to the contrary in this Section 14.01, prior to the close of business on the
Business Day immediately preceding January 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at the Applicable Conversion Rate, at any time during any calendar quarter commencing after the calendar quarter ending on
June 30, 2019 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the
last Trading Day of the immediately preceding calendar quarter is greater than or equal to 110% of the Conversion Price on each applicable Trading Day. Provided that no Mandatory Conversions pursuant to Section 14.02 are occurring during a
particular calendar quarter, the Company shall determine at the end of the immediately preceding calendar quarter whether the Notes may be surrendered for conversion in accordance with this clause Section 14.01(b)(iv) and shall notify the
Holders, the Conversion Agent and the Trustee if the Notes become convertible in accordance with this clause (iv). Such notice shall be delivered no later than no later than the open of business on the sixth Business Day of the month immediately
after the end of the immediately preceding calendar quarter. 

  
 54 













 (v) Notwithstanding anything to the contrary in this
Indenture: (a) the maximum amount a converting holder is entitled to convert within any one calendar quarter, pursuant to Section 14.01(b)(i) and Section 14.01(b)(iv), shall not exceed 30% of the original aggregate principal amount of
the Note(s) held by such converting holder (“Voluntary Conversion Limitation”) and upon delivery of any Conversion Notice (including through the applicable procedures of the Depositary), such converting holder shall be deemed to
represent and warrant that such limitation is not exceeded; and (b) conversions pursuant to this Section 14.01(b)(i) and Section 14.01(b)(iv) may not occur within the same calendar quarter as a Mandatory Conversion. The Trustee and
the Conversion Agent shall have no obligation to monitor the Voluntary Conversion Limitation and shall have no liability for any conversions made by holders exceeding the Voluntary Conversion Limitation. 

Section 14.02. Mandatory Conversion. For fifteen consecutive months, the first month beginning on April 3,
2019 and the last month ending on June 30, 2020 (each, a “Mandatory Conversion Month”), provided that, if the average Daily VWAP for the last 5 Trading Days ending on, and including, the last Trading Day of the
applicable Mandatory Conversion Month is greater than or equal to the Trigger Price, the Company shall convert $1,666,666 of aggregate outstanding amount of the Notes, together with the payment of the accrued and unpaid interest (“Mandatory
Conversion”), on a pro rata basis, to the Holders in whose name any Note is registered on the Note Register at the close of business on the date of the Mandatory Conversion Notice, into shares of Common Stock (plus cash in lieu of
fractional shares of Common Stock in accordance with Section 14.03) at a conversion rate of 0.15129 (the “Mandatory Conversion Rate”, together with the Applicable Conversion Rate, the “Indenture Conversion
Rates”) per $1.00 principal amount of Exchange Notes (including PIK Notes). The Company shall deliver to the Holders of the Exchange Notes, the Trustee and the Conversion Agent (if other than the Trustee) a notice of the conversion
of the Exchange Notes no later than the open of business on the third Business Day of the month immediately after the end of the immediately preceding Mandatory Conversion Month (a “Mandatory Conversion Notice”), which notice shall
specify that the Mandatory Conversion shall occur on a pro rata basis on the sixth Business Day following the date of such notice (the “Mandatory Conversion Date”); provided that, all Mandatory Conversions shall be suspended during
the period beginning on the date a Change of Control Offer is made and continuing to, and including, the applicable Change of Control Settlement Date, and shall resume after the Change of Control Settlement Date. The Mandatory Conversion Notice
shall state that the Mandatory Conversion is occurring, the Mandatory Conversion Rate, and the Mandatory Conversion Price in effect on the Mandatory Conversion Date, and any election by the Company to pay the interest in cash, shares of common stock
or as a PIK Payment. 
 In case of a Physical Note subject to Mandatory Conversion, the Holder shall surrender its Note on
the Conversion Date for payment, and the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Physical Note so surrendered a new Physical Note or Notes in authorized denominations in
an aggregate principal amount equal to the unconverted portion of the surrendered Physical Note. The Company shall have no obligation to pay shares of Common Stock or accrued and unpaid interest until the Holder has surrendered its Notes for
payment. 

  
 55 













 On the Mandatory Conversion Date, the Company shall deliver an
Officers’ Certificate to the Trustee and the Conversion Agent (if other than the Trustee), stating that all of the conditions listed below (the “Equity Conditions”) are satisfied on each day during the period
(x) commencing on, and including, the date of the Mandatory Conversion Notice and (y) ending on, and including, the Mandatory Conversion Date. The Equity Conditions are as follows: 

(i) either (1) all shares of Common Stock issuable upon conversion of the Exchange Notes and held by a non-Affiliate of the Company shall be eligible for sale without the need for registration under any applicable federal or state securities laws or (2) a shelf registration statement registering the resale of
the shares of Common Stock issuable upon conversion of the Exchange Notes has been filed by the Company and been declared effective by the SEC or is automatically effective and is available for use, and the Company expects such shelf registration
statement to remain effective and available for use from the Mandatory Conversion Date until thirty days following the Mandatory Conversion Date; 

(ii) the Common Stock to be delivered on such conversion is listed or traded on The New York Stock Exchange, The NASDAQ Global
Select Market, The NASDAQ Global Market, The NASDAQ Capital Market, or any of their respective successors (each, an “Eligible Market”) and shall not then be suspended from trading on such Eligible Market; 

(iii) at or prior to the settlement date of the Mandatory Conversion, for any Exchange Notes validly surrendered for conversion
prior to the Mandatory Conversion Date in accordance with the terms of this Indenture, the Company shall have delivered and paid the number of shares of Common Stock and the amount of cash due upon conversion of the Exchange Notes to the Holders of
such Exchange Notes in accordance with Section 14.02; 
 (iv) shares of Common Stock to be issued upon conversion may be
issued in full without violating the rules or regulations of The New York Stock Exchange or any other applicable Eligible Market on which the Common Stock delivered upon conversion is then listed or trading; and 

(v) no Event of Default shall have occurred and be continuing. 

For the avoidance of doubt, subject to the satisfaction of the conditions set forth in this Section 14.02, $1,666,666
aggregate principal amount of Exchange Notes (including PIK Notes) shall convert each month for fifteen consecutive months on a pro rata basis. Simultaneously with the execution of this Indenture, the Company has issued $43,000,000 in aggregate
principal amount of 5.0% Voluntary Convertible Senior Notes due 2024 (CUSIP 29266S AC0) (the “Voluntary Notes”) pursuant to the Indenture between the Company and the Trustee, dated April 3, 2019 (the “Voluntary
Indenture”). Upon the completion of (i) the last Mandatory Conversion on or about July 13, 2020, or (ii) on July 13, 2020, if the Company does not elect to make the last Mandatory Conversion on or before
July 20, 2020 (such date, as applicable, the “Exchange Trigger Date”), the Company shall permit any Notes that remain outstanding to be exchanged into Voluntary Notes (the “New Voluntary Notes”). The Company
shall use commercially reasonable efforts to assure that the exchange will be accomplished in a manner, such that the New Voluntary Notes will be DTC eligible and otherwise fungible (including with respect to transferability and the payment of
interest) with the then outstanding Voluntary Notes 

  
 56 













 
so as to bear the same CUSIP number (CUSIP 29266S AC0) as the Voluntary Notes issued on the date hereof. Without limiting the foregoing, the Company will use commercially reasonable efforts
to timely comply with all applicable laws, including without limitation, applicable securities laws, in order to ensure that any such exchange may take place on or after the Exchange Trigger Date. 

Notwithstanding anything to the contrary in this Indenture, the total principal amount of the Exchange Notes (including PIK
Notes) subject to Mandatory Conversion shall not exceed $25,000,000. 
 Section 14.03. Conversion Procedure;
Settlement Upon Conversion. 
 (a) Subject to this Section 14.03, Section 14.04(b) and
Section 14.08(a), upon conversion of any Note pursuant to Section 14.01, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1.00 principal amount of Notes being converted, cash
(“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.03 (“Physical
Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.03
(“Combination Settlement”), at its election, as set forth in this Section 14.03. 
 (i)
All conversions for which the relevant Conversion Date occurs on or after January 1, 2024 shall be settled using the same Settlement Method. 

(ii) Except for any conversions for which the relevant Conversion Date occurs on or after January 1, 2024,
the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates. 

(iii) If, in respect of any Conversion Date (or one of the periods described in the third immediately
succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the
Company shall deliver such Settlement Notice to converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in
the case of any conversions for which the relevant Conversion Date occurs on or after January 1, 2024, no later than January 1, 2024). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately
preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar
Amount per $1.00 principal amount of Notes shall be equal to $1.00. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the
Specified Dollar Amount per $1.00 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its 

  
 57 













 
Conversion Obligation but does not indicate a Specified Dollar Amount per $1.00 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1.00 principal amount of
Notes shall be deemed to be $1.00. 
 (iv) The cash, shares of Common Stock or combination of cash and shares
of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows: 

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical
Settlement, the Company shall deliver to the converting Holder in respect of each $1.00 principal amount of Notes being converted a number of shares of Common Stock equal to the Applicable Conversion Rate in effect on the Conversion Date plus cash
in lieu; 
 (B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by
Cash Settlement, the Company shall pay to the converting Holder in respect of each $1.00 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive Trading Days during
the related Observation Period; and 
 (C) if the Company elects (or is deemed to have elected) to satisfy
its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1.00 principal amount of Notes being converted, a Settlement Amount equal to the sum of the
Daily Settlement Amounts for each of the 25 consecutive Trading Days during the related Observation Period plus cash in lieu. 

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

(b) Subject to Section 14.03(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 14.03(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 

  
 58 













 
(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 14.03(h). The Trustee (and if different, the Conversion Agent) shall notify
the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change
Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03. Notwithstanding anything to the contrary, no holder may deliver a Notice of
Conversion (i) during the period of time commencing on the first day of a Mandatory Conversion Calendar Quarter and the open of business on the third Business Day of such Mandatory Conversion Calendar Quarter or (ii) during a Mandatory
Conversion Calendar Quarter in which the Company has delivered a Mandatory Conversion Notice. 
 If more than one Note shall
be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted
thereby) so surrendered. 
 (c) A Note shall be deemed to have been converted immediately prior to the close of business on
the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.04(b) and Section 14.08(a), the Company shall pay or deliver, as
the case may be, the consideration due in respect of the Conversion Obligation on the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second Business Day immediately
following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to a converting Holder, the Company shall issue or cause to be issued, and deliver to the stock transfer
agent or to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion
Obligation. 
 (d) In case any Physical 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 Physical Note so surrendered a new Physical Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the
surrendered Physical Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar
governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Physical Notes issued upon such conversion being different from the name of the Holder of the old Physical Notes
surrendered for such conversion. 

  
 59 













 (e) If a Holder submits a Note for conversion, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case
the Holder shall pay that tax. The stock transfer 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 14.05, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 14. 

(g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall
make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee. 

(h) Upon conversion, except as set forth in Section 14.02, a Holder shall not receive any separate cash payment for
accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid
interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or
forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted
after the close of business on a Regular Record Date, 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 (including a PIK Payment, if applicable) 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,
however, must be accompanied by funds equal to the amount of interest payable on the Notes so converted (regardless of whether a PIK Payment will be made or shares of common stock will be issued, and in the event of a PIK Payment or distribution of
shares of common stock, the interest payable will be the cash equivalent of any PIK Payment); provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any
Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date shall receive the
full interest payment due on the Maturity Date in cash regardless of whether their Notes have been converted following such Regular Record Date. 

(i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of
record as of the close of business on the relevant 

  
 60 













 
Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to
satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 

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

Section 14.04. Increased Applicable Conversion Rate Applicable to Certain Notes Surrendered in Connection with
Make-Whole Fundamental Changes. (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date, and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the
Company shall, under the circumstances described below, increase the Applicable Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described
below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date
of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the
proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). 

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to
Section 14.01(b)(iii), the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.03; provided, however, that
if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion
of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1.00 principal amount of
converted Notes equal to the Applicable Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day
following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five
Business Days after such Effective Date. 

  
 61 













 (c) The number of Additional Shares, if any, by which the Applicable
Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (in each case, the “Effective Date”), and the price
paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “Stock Price”). If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental
Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five
Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith
determination, to account for any adjustment to the Applicable Conversion Rate that becomes effective, or any event requiring an adjustment to the Applicable Conversion Rate where the Ex-Dividend Date,
Effective Date (as such term is used in Section 14.05) or expiration date of the event occurs during such five consecutive Trading Day period. 

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the
Applicable Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Applicable
Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Applicable Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be
adjusted in the same manner and at the same time as the Applicable Conversion Rate as set forth in Section 14.05. 
 (e)
The following table sets forth the number of Additional Shares of Common Stock by which the Applicable Conversion Rate shall be increased per $1.00 principal amount of Notes pursuant to this Section 14.04 for each Stock Price and Effective Date
set forth below:

 The exact Stock Price and Effective Date may not be set forth in the table above, in which
case: 
 (i) if the Stock Price is between two Stock Prices in the table 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 Stock Prices and the earlier and later
Effective Dates, as applicable, based on a 365-day year; 

  
 62 













 (ii) if the Stock Price is greater than $40.00 per share
(subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Applicable Conversion Rate; and 

(iii) if the Stock Price is less than $6.61 per share (subject to adjustment in the same manner as the Stock
Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Applicable Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Applicable Conversion Rate per $1.00 principal amount of Notes exceed 0.1512 shares of
Common Stock, subject to adjustment in the same manner as the Applicable Conversion Rate pursuant to Section 14.05. 

(f) Nothing in this Section 14.04 shall prevent an adjustment to the Applicable Conversion Rate pursuant to
Section 14.05 in respect of a Make-Whole Fundamental Change. 
 Section 14.05. Adjustment of Indenture
Conversion Rates. The Indenture Conversion Rates 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 Indenture Conversion Rates if Holders
of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the
Notes, in any of the transactions described in this Section 14.05, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Indenture Conversion Rates, multiplied by the principal amount
(expressed in thousands) of Notes held by such Holder. 
 (a) If the Company issues shares of Common Stock as a dividend or
distribution on shares of the Common Stock, or if the Company effects a share split or share combination, the Indenture Conversion Rates shall be adjusted based on the following formula: 

 
 



 
 where, 
  

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

			
	 CR’
	  	 =
	  	 the Indenture Conversion Rates in effect immediately after the open of business on such
Ex-Dividend Date or Effective Date, as the case may be;

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



  
 63 














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


 Any adjustment made under this Section 14.05(a) shall become effective immediately after the open of
business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or
distribution of the type described in this Section 14.05(a) is declared but not so paid or made, the Indenture Conversion Rates shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend
or distribution, to the Indenture Conversion Rates that would then be in effect if such dividend or distribution had not been declared. 

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling
them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the
Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Indenture Conversion Rates shall be increased based on the following formula: 

 
 



 
 where, 
  

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

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

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

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

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


 Any increase made under this Section 14.05(b) shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after
the expiration of such rights, options or warrants, the Indenture 

  
 64 













 
Conversion Rates shall be decreased to the Indenture Conversion Rates that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Indenture Conversion Rates shall be decreased to the Indenture Conversion Rates that would then be in
effect if such Ex-Dividend Date for such issuance had not occurred. 
 For purposes
of this Section 14.05(b) and for the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the
Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of
such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than
cash, to be determined in good faith by the Board of Directors. 
 (c) If the Company distributes shares of its Capital
Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends,
distributions or issuances as to which an adjustment was effected pursuant to Section 14.05(a) or Section 14.05(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section 14.05(d)
shall apply, (iii) except as otherwise provided in Section 14.12, rights issued under a stockholder rights plan of the Company, (iv) distributions of Reference Property in exchange for or upon conversion of the Common Stock in a Share
Exchange Event and (v) Spin-Offs as to which the provisions set forth below in this Section 14.05(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to
acquire Capital Stock or other securities, the “Distributed Property”), then the Indenture Conversion Rates shall be increased based on the following formula: 

 
 



 
 where, 
  

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

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

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



  
 65 














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


 Any increase made under the portion of this Section 14.05(c) above shall become effective immediately
after the open of business on the Ex-Dividend Date for such distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate; provided that if such
distribution is not so paid or made, the Indenture Conversion Rates shall be decreased to the Indenture Conversion Rates that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as
defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1.00 principal amount
thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock
equal to the Indenture Conversion Rates in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of
this Section 14.05(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock
over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution. 

With respect to an adjustment pursuant to this Section 14.05(c) where there has been a payment of a dividend or other
distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading
on a U.S. national securities exchange (a “Spin-Off”), the Indenture Conversion Rates shall be increased based on the following formula: 

 
 



 
 where, 
  

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

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

			
	 FMV0
	  	 =
	  	 the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the
Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity
interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”);
and



  
 66 














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


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

For purposes of this Section 14.05(c) (and subject in all respect to Section 14.12), rights, options or warrants
distributed by the Company to all or substantially all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances),
which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also
issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.05(c) (and no adjustment to the Indenture Conversion Rates under this Section 14.05(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 Indenture Conversion Rates shall be made
under this Section 14.05(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options
or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and
Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise
by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect
thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Indenture Conversion Rates under this Section 14.05(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 purchase (x) the Indenture Conversion Rates shall be readjusted 

  
 67 













 
as if such rights, options or warrants had not been issued and (y) the Indenture Conversion Rates 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 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 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
Indenture Conversion Rates shall be readjusted as if such rights, options and warrants had not been issued. 
 For purposes
of Section 14.05(a), Section 14.05(b) and this Section 14.05(c), if any dividend or distribution to which this Section 14.05(c) is applicable also includes one or both of: 

(A) a dividend or distribution of shares of Common Stock to which Section 14.05(a) is applicable (the “Clause A
Distribution”); or 
 (B) a dividend or distribution of rights, options or warrants to which Section 14.05(b)
is applicable (the “Clause B Distribution”), 
 then, in either case, (1) such dividend or distribution, other than
the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.05(c) is applicable (the “Clause C Distribution”) and any Indenture Conversion Rates adjustment
required by this Section 14.05(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 Indenture
Conversion Rates adjustment required by Section 14.05(a) and Section 14.05(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend
Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A
Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of
Section 14.05(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.05(b). 

(d) If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, the Indenture
Conversion Rates shall be adjusted based on the following formula: 
  
 



 
 where, 
  

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



  
 68 














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

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

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


 Any increase pursuant to this Section 14.05(d) shall become effective immediately after the open of
business on the Ex-Dividend Date for such dividend or distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate; provided that if such dividend or
distribution is not so paid, the Indenture Conversion Rates shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Indenture Conversion Rates that would then be in
effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above),
in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1.00 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have
received if such Holder owned a number of shares of Common Stock equal to the Indenture Conversion Rates on the Ex-Dividend Date for such cash dividend or distribution. 

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to
the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on,
and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Indenture Conversion Rates shall be increased based on the following formula: 

 
 



 
 where, 
  

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

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

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



  
 69 














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

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

			
	 SP’
	 	 =
	  	 the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on,
and including, the Trading Day next succeeding the date such tender or exchange offer expires.


 The increase to the Indenture Conversion Rates under this Section 14.05(e) shall occur at
the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which
Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to
“10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and the Conversion Date in determining the
Indenture Conversion Rates and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the
10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and such Trading Day in determining the Indenture Conversion Rates as of such Trading Day. In addition, if the Trading Day next succeeding the
date such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding
paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange
offer expires to, and including, the last Trading Day of such Observation Period. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. If the Company or any of its Subsidiaries is obligated to purchase
Common Stock pursuant to any such tender offer or exchange offer, but the Company or any of its Subsidiaries is ultimately prevented by applicable law from effecting all or any portion of such purchases or all or any portion of such purchases are
rescinded, the Conversion Rate shall immediately be readjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchase of Common Stock that had
been effected. 
 (f) Notwithstanding this Section 14.05 or any other provision of this Indenture or the Notes, if a
Indenture Conversion Rates adjustment becomes effective on any Ex-Dividend Date, 

  
 70 













 
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 14.03(i) based on an adjusted Indenture Conversion Rates for such Ex-Dividend Date, then, notwithstanding
the Indenture Conversion Rates adjustment provisions in this Section 14.05, the Indenture Conversion Rates adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder.
Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 

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

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.05, and to the
extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Indenture Conversion Rates by any amount for a
period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on
which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Indenture Conversion Rates to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in
connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Indenture Conversion Rates is increased pursuant to either of the preceding two sentences, the Company
shall deliver to the Holder of each Note a notice of the increase at least 15 days prior to the date the increased Indenture Conversion Rates takes effect, and such notice shall state the increased Indenture Conversion Rates and the period during
which it will be in effect. 
 (i) Notwithstanding anything to the contrary in this Article 14, the Indenture Conversion
Rates shall not be adjusted: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present
or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

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

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

  
 71 













 (iv) solely for a change in the par value of the Common
Stock; or 
 (v) for accrued and unpaid interest, if any. 

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the
nearest one-ten thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion
Rate; provided that the Company shall 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%, (i) on the Conversion Date for any Notes, (ii) on each Trading Day of the Conversion Period in respect of any Notes, and (iii) on any Fundamental Change effective date, unless such
adjustment has already been made. 
 (k) Whenever the Indenture Conversion Rates is adjusted as herein provided, the Company
shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Indenture Conversion Rates after such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Indenture Conversion Rates and may assume without
inquiry that the last Indenture Conversion Rates 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 Indenture Conversion Rates setting forth the
adjusted Indenture Conversion Rates and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Indenture Conversion Rates to each Holder. Failure to deliver such notice shall not affect the
legality or validity of any such adjustment. 
 (l) For purposes of this Section 14.05, the number of shares of Common
Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but
shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

Section 14.06. Adjustments of Prices. Whenever any provision of this Indenture requires the Company to
calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a
Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Applicable Conversion Rate that becomes effective, or any event requiring an adjustment to the Applicable
Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the
Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 
 Section 14.07. 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


  
 72 













 
are presented for conversion (assuming delivery of the maximum number of Additional Shares pursuant to Section 14.04 and that at the time of computation of such number of shares, all such
Notes would be converted by a single Holder and that Physical Settlement were applicable). 
 Section 14.08. Effect
of Recapitalizations, Reclassifications and Changes of the Common Stock. 
 (a) In the case of: 

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a
subdivision or combination or a change of par value or to no par value), 
 (ii) any consolidation, merger,
combination or similar transaction involving the Company, 
 (iii) any sale, assignment, conveyance, lease or
other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety or 

(iv) any statutory share exchange, 

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or
assets (including cash or any combination thereof) (any such event, a “Share Exchange Event”), then, at and after the effective time of such Share Exchange Event, the right to convert each $1.00 principal amount of Notes shall be
changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock
equal to the Applicable Conversion Rate immediately prior to such Share Exchange 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 Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or purchasing
Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1.00 principal amount of Notes; provided, however, that
at and after the effective time of the Share Exchange Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with
Section 14.03 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.03 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to
deliver upon conversion of the Notes in accordance with Section 14.03 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such
Share Exchange Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a
single type of consideration (determined based in 

  
 73 













 
part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and
amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the
holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of
the Common Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) the consideration due upon conversion of each
$1.00 principal amount of Notes shall be solely cash in an amount equal to the Applicable Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.04), multiplied by the price
paid per share of Common Stock in such Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The
Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other
adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If, in the case of any Share Exchange 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 Share Exchange Event, then such supplemental indenture shall also be executed by such other Person and shall
contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in
Article 15. 
 (b) When the Company executes a supplemental indenture pursuant to subsection (a) of this
Section 14.08, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property
after any such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution
of such supplemental indenture to be delivered to each Holder within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 

(c) The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this
Section 14.08. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, as set forth
in Section 14.01 and Section 14.03 prior to the effective date of such Share Exchange Event. 
 (d) The above
provisions of this Section shall similarly apply to successive Share Exchange Events. 

  
 74 













 Section 14.09. Certain Covenants. (a) The Company
covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and
interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c) The Company further
covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated
quotation system, any Common Stock issuable upon conversion of the Notes. 
 Section 14.10. 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 Applicable Conversion Rate (or any adjustment thereto) or whether any facts exist that may
require any adjustment (including any increase) of the Applicable 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 14.08 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 14.08 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 Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither
the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has
delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively
rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). 

Section 14.11. Notice to Holders Prior to Certain Actions. In case of any: 

  
 75 













 (a) action by the Company or one of its Subsidiaries that would require an
adjustment in the Applicable Conversion Rate pursuant to Section 14.05 or Section 14.12; 
 (b) Share Exchange
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 delivered to each Holder, as promptly as possible but in any event at least 20 days prior to the
applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders
of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Share Exchange 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 Share Exchange 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, Share Exchange Event, dissolution, liquidation or winding-up. 

Section 14.12. Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon
conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear
such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common
Stock in accordance with the provisions of the applicable stockholder rights plan, the Applicable Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock
Distributed Property as provided in Section 14.05(c), subject to readjustment in the event of the expiration or termination of such rights. 

Section 14.13. Ownership Limitation. 

(a) Notwithstanding the provisions of Section 14.01, during any period of time in which a Holder’s “beneficial
ownership” (as determined in accordance with Rule 13d-3 of the Exchange Act) of Common Stock is less than 9.5%, the Holder shall not have the right to voluntarily convert, and the Company shall not effect
a Mandatory Conversion, of all or any portion of the Notes, and shall not be entitled to receive shares of Common Stock in exchange therefore, if (but only to the extent that) upon and after giving effect to such conversion (and issuance of any
shares of Common Stock in satisfaction of any Fundamental Change or Make-Whole Fundamental Change, as the case may be), and taking into account the method of settlement elected by (or deemed to have been elected by) the Company under
Section 14.03, such Holder (together with such Holder’s Affiliated Parties (including shares held by any “group” of which the Holder or any of its Affiliates and any other persons or entities whose


  
 76 













 
beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (the “Affiliated Parties”) (including
shares held by any “group” of which the Holder or any of its Affiliated Parties is a member)) would have beneficial ownership of more than 9.5% of the total number of shares of Common Stock then issued and outstanding
(the “Ownership Limitation”); provided, that, a Holder may, at its option and upon not less than sixty-one (61) days’ prior notice to the Company, elect to
increase the Ownership Limitation up to 19.99% of the total number of shares of Common Stock then issued and outstanding. Any such increase will not be effective until the 61st day after such notice is delivered to the Company. The Company hereby
covenants and agrees not to adopt any shareholder rights plan or take any other action which would have the effect of restricting or adversely affecting the Holder’s election to change such threshold percentage. When submitting any Conversion
Notice through the applicable procedures of the Depositary, such holder shall be deemed to represent and warrant that such conversion will not result in a breach of the Ownership Limitation. 

The Trustee and the Conversion Agent shall have no obligation to monitor a Holder’s beneficial ownership of Common Stock
or the Ownership Limitation and shall have no liability for conversions made by beneficial owners exceeding the Ownership Limitation. 

(b) For the avoidance of doubt, if a Holder, pursuant to Section 14.01(a), or the Company, pursuant to Section 14.02,
purports to convert the Principal Amount of any Notes into shares of Common Stock hereunder and any delivery otherwise owed to such Holder hereunder is not made, in whole or in part, as a result of the Ownership Limitation or any other limitation
set forth herein, then the Holder’s rights under the relevant Notes, or portion thereof, pursuant to which such delivery was not made will not be extinguished and, instead such Notes, or portion thereof, will be deemed to have never been
converted. 
 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 at any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1.00 or an integral multiple of $1.00,
on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change
Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record
as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. 

  
 77 













 (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 or tender agent appointed by the
Company to facilitate the repurchase (the “Tender 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 or Tender Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent or the principal
office of the Tender Agent located in the contiguous United States as notified by the Tender Agent to Holders and the Trustee, as the case may be, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures
of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor. 

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

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

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1.00 or an integral
multiple thereof; and 
 (iii) that the Notes are to be repurchased by the Company pursuant to the applicable
provisions of the Notes and this Indenture; 
 provided, however, that if the Notes are Global Notes, the Fundamental Change
Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent or Tender Agent, as the case may be, 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 or Tender Agent, as the case may be, in accordance
with Section 15.03. 
 The Paying Agent or Tender Agent, as the case may be, shall promptly notify the Company of the
receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 

  
 78 













 (c) On or before the fifth (5th) Business Day after the occurrence of the
effective date of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee, Conversion Agent (in the case of a Conversion Agent other than the Trustee) and the Paying Agent (in the case of a Paying Agent other than the
Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of
Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall
publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public
medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 
 (i) the
events causing the Fundamental Change and whether such Fundamental Change is a Make-Whole Adjustment Event; 

(ii) the date of the Fundamental Change; 

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

(iv) the Fundamental Change Repurchase Price; 

(v) the Fundamental Change Repurchase Date; 

(vi) the name and address of the Paying Agent or Tender Agent, as the case may be, and the Conversion Agent, if
applicable; 
 (vii) if applicable, the Applicable Conversion Rate and any adjustments to the Applicable
Conversion Rate; 
 (viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has
been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and 

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights
or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02. 
 At the
Company’s request, delivered at least two Business Days prior to the Fundamental Change Company Notice is to be sent, 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 or Tender Agent, as the case may be, 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) 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 or the principal office of the Tender
Agent located in the contiguous United States as notified by the Tender Agent, as the case may be, to Holders and the Trustee 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, 
 (ii) if Physical Notes have been issued,
the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and 

(iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change
Repurchase Notice, which portion must be in principal amounts of $1.00 or an integral multiple of $1.00; 
 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 or Tender Agent, as the case may be, 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 or Tender Agent, as the case may be, appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental
Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions in Section 15.02) and (ii) the time of book-entry transfer or the delivery of
such Note to the Trustee (or other Paying Agent or Tender Agent, as the case may be, appointed by the Company) by the Holder thereof in the manner required by Section 15.02 by mailing checks for the amount payable to the Holders of


  
 80 













 
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 or
Tender Agent, as the case may be, appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect to the Notes that have
been properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or
the Notes have been delivered to the Trustee or Paying Agent or Tender Agent, as the case may be,) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price
and, if applicable, accrued and unpaid interest). 
 (c) Upon surrender of a Physical 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 Physical Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Physical Note
surrendered. 
 Section 15.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection
with any repurchase offer, the Company will, if required: 
 (a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act; 

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

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

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 corporation or other entity into which any authenticating agent may be merged or converted or with which it may be
consolidated, or any corporation or other entity resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding to the corporate trust business of any
authenticating agent, shall be the successor of the authenticating agent hereunder, if such successor corporation or other entity is otherwise eligible under this Section 17.10, without the execution or filing of any paper or any further act on
the part of the parties hereto or the authenticating agent or such successor corporation or other entity. 
 Any
authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such
authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible under this Section, the Trustee may appoint a successor
authenticating agent (which may be the Trustee), shall give written notice of such appointment to the Company and shall deliver notice of such appointment to all Holders. 

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.

Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired. 

Section 17.13. Waiver of Jury Trial. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

Section 17.14. Force Majeure. In no event shall the Trustee be responsible or liable for any failure or
delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military
disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts that
are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

Section 17.15. Calculations. The Company shall be responsible for making all calculations called for under the
Notes. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes and the
Applicable Conversion Rate of the Notes. The Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company shall provide a schedule of
its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without


  
 85 













 
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. 

Section 17.16. Withholding Taxes. If the Company or one of its withholding agents is required by applicable
law to withhold any taxes as a result of an adjustment to the Applicable Conversion Rate, the Company may, at its option, withhold or cause to be withheld such amount from any concurrent or subsequent payments of cash or shares of Common Stock on
the Notes, and such withheld amounts will be treated as having been paid with respect to such Notes provided such amounts are timely paid over to the applicable governmental authority in accordance with applicable law. If the Company or one of its
withholding agents is required by applicable law to withhold any taxes in connection with any payments of cash or shares of Common Stock on the Notes, the Company may, at its option, withhold or cause to be withheld such amount from such payments,
and such withheld amounts will be treated as having been paid with respect to such Notes provided such amounts are timely paid over to the applicable governmental authority in accordance with applicable law. For purposes of any set off against
shares of Common Stock paid on the Notes, each share of Common Stock will be deemed to have a value equal to the Daily VWAP of the Common Stock on the date such withholding is required to be performed by the Company or its withholding agent. 

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

 [FORM OF REVERSE OF NOTE] 

Endologix, Inc. 
 5.0% Mandatory
Convertible Senior Note due 2024 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its
5.0% Mandatory Convertible Senior Notes due 2024 (the “Notes”), limited to the aggregate principal amount of $[            ], all issued or to be issued under and pursuant
to an Indenture dated as of April [    ], 2019 (the “Indenture”), between the Company and Wilmington Trust, 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. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture. 

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be
declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain
exceptions set forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all
payments and deliveries in respect of conversions, the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date (if applicable) 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. 

Each Holder shall have the right to receive payment or delivery, as the case may be, of (x) the principal (including the
Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money, or
shares of Common Stock, or through an increase of the principal amount of the outstanding Notes or the issuance of paid-in-kind Notes, as the case may be, herein
prescribed. 

  
 A-5 













 The Notes are issuable in registered form without coupons in minimum
denominations of $1.00 principal amount and integral multiples in excess 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. 

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 $1.00 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. 

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon
the occurrence of certain conditions specified in the Indenture, prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1.00 or an integral multiple thereof, into
cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, at the Applicable Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

You must check one, and only one, of the following two boxes: 

☐  The undersigned is requesting registration in a name other than that of the converting holder. The converting holder
acknowledges sole responsibility for the payment of any taxes that may be owing by reason thereof. If any taxes are payable upon transfer, they have already been paid.

 To avoid the application of “backup withholding” under U.S. federal income tax law, each converting
holder (or other payee) should complete, sign, and deliver an Internal Revenue Service (“IRS”) Form W-9 (in the case of a U.S. person or a resident alien) or an IRS Form W-8BEN or other appropriate IRS Form W-8 (in the case of a foreign holder). IRS Forms W-9 and
W-8 are available on the IRS’s website at http://www.irs.gov/. Failure to include a properly completed IRS Form W-9 or applicable IRS Form W-8 may result in the application of U.S. backup withholding. 
 In addition, Notes surrendered for
conversion during the period from the Close of Business on any Record Date to the Open of Business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted,
except as specified below. THE INDENTURE REQUIRES THIS CASH PAYMENT EVEN IF THE INTEREST PAYABLE ON THE IMMEDIATELY FOLLOWING INTEREST PAYMENT DATE IS PAYABLE IN PIK NOTES OR SHARES OF COMMON STOCK. IN THIS EVENT, EVEN THOUGH THE HOLDER HAS
REMITTED A CASH PAYMENT WITH THE CONVERSION NOTICE, THE HOLDER WILL NOT RECEIVE ANY CASH AS THE INTEREST PAYMENT BUT WILL RECEIVE ONLY PIK NOTES OR SHARES OF COMMON STOCK. However, such payment need not be made: (i) if the conversion
follows the Record Date immediately preceding the Maturity Date; (ii) if the Issuer has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the first Business Day immediately following the
corresponding Interest Payment Date; or (iii) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such Note. Where payment is owed, no conversion will occur before this payment has
been received by the Issuer. Wiring instructions for any such payment of funds may be obtained by contacting the Trustee at svilhauer@WilmingtonTrust.com.
