Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a
result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer. 

None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to
exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, or (ii) any Notes, or a portion of any Note,
surrendered for repurchase (and not withdrawn) in accordance with Article 15. 
 All Notes issued upon any registration of transfer or
exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or
exchange. 
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject
to the fourth paragraph from the end of Section 2.05(c), all 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


  
 15 













 
any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance
with the second immediately succeeding paragraph. 
 The Depositary shall be a clearing agency registered under the Exchange Act. The
Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the
Depositary, and deposited with the Trustee as custodian for Cede & Co. 
 If (i) the Depositary notifies the Company at any
time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed 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 written certification, proxy or other authorization furnished by the Depositary or


  
 16 













 
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 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. 

  
 17 













 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. 

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. 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 

  
 18 













 
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 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 terminate and 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. 

  
 20 













 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 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 

  
 21 













 
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 (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 

  
 22 













 
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 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, 2020) an Officers’ Certificate stating whether the signers thereof have


  
 23 













 
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 or the Collateral Agent, 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, or as the Collateral Agent may reasonably request, in order to grant, preserve,
protect and perfect the validity and priority of the security interests and Liens created, or intended to be created, by the Security Documents in the Collateral to the extent required thereunder and subject to the Subordination Agreement. 

Section 4.10. After-Acquired Property. From and after the date hereof and subject to certain limitations set forth in the
Security Documents and the Subordination Agreement, if the Company acquires any property which is of a type constituting Collateral under the Junior Lien Security Agreement or any other Security Document, it shall, to the extent necessary and
required by the Junior Lien Security Agreement or any other Security Document, as soon as practicable after the acquisition thereof execute and deliver such security instruments, mortgages, surveys, title insurance policies, financing statements and
such certificates and Opinions of Counsel as are reasonably necessary to vest in the Collateral Agent a perfected security interest in such after-acquired property to the extent such security interest can be perfected by filing a UCC financing
statement and to have such after-acquired property added to the Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such after-acquired property to the same extent and with the same
force and effect but in each case subject to the Subordination Agreement. 
 Section 4.11. Maintenance of Collateral. The
Company shall (i) at all times maintain, preserve and protect all property material to the conduct of its business and keep such property in good repair, working order and condition (other than wear and tear occurring in the ordinary course of

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 equivalent) or more (excluding any

 25 













 (j) the Company or any Significant Subsidiary (or any group of Subsidiaries that, taken

bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of

its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or 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. 

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 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


  
 26 













 
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 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,


  
 27 













 
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. 

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. 

  
 28 













 Section 6.05. Application of Monies Collected by Trustee. Subject to the
Subordination Agreement, 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 and to the Collateral Agent under this Indenture and the Security Documents; 

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

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

  
 29 













 (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 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 

  
 30 













 
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 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 and to the Collateral Agent 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 

  
 31 













 
the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in
its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to
exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it in its 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 gross negligence and willful misconduct on the part of the Trustee, the Trustee may conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or
opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not
confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (b) the Trustee shall not be liable
for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; 

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

(e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters
relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes; 

(f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to
the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless a Responsible Officer of the Trustee had actual knowledge of such event; 

  
 32

 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

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 payment of any amounts due under this Section 7.06 shall not be subordinate
to any other liability or indebtedness of the Company and in order to secure the Company’s payment obligations in this Section 7.06 the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee
other than money or property held in trust to pay principal of and interest on particular Notes, subject to the Subordination Agreement. 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. 

  
 35 













 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 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, 

  
 36 













 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, upon 30 days’ prior written notice, remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company
of such nomination the Company objects thereto, in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment
of a successor trustee. 
 (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the
provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 

Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request
of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the
benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 
 No successor
trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at
the written direction and at the expense of the Company shall 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 

  
 37 













 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 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. 

Section 7.13. Security Documents; Subordination Agreement. By their acceptance of the Notes, each of the Holders hereby
(a) authorizes and direct the Trustee and Collateral Agent, as the case may be, to execute and deliver the Subordination Agreement and any other Security Documents in which the Trustee or the Collateral Agent, as applicable, is named as a
party, including any Security Documents executed after the date hereof and (b) agrees that it will be bound by and will take no actions contrary to the provisions of the Subordination Agreement. It is hereby expressly acknowledged and agreed
that, in doing so, the Trustee and Collateral Agent are (a) expressly authorized to make the representations attributed to Holders in any such agreements and (b) not responsible for the terms or contents of such agreements, or for the
validity or enforceability thereof, or the sufficiency thereof for any purpose. Whether or not so expressly stated therein, in entering into, or taking (or forbearing from) any action under the Subordination Agreement or any other Security
Documents, the Trustee and the Collateral Agent each shall have all of the rights, benefits, immunities, indemnities and other protections granted to it under this Indenture, the Security Documents and the Subordination Agreement (in addition to
those that may be granted to it under the terms of such other agreement or agreements). In the event of any conflict or inconsistency between the provisions of the Subordination Agreement, on the one hand, and this Indenture, the Notes, the Exchange
Agreement or any other Security Document, or any other document, agreement or other instrument executed and delivered pursuant to this Indenture, the Notes, the Exchange Agreement or any other Security Document, on the other hand, the provisions of
the Subordination Agreement shall control.

 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 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 

  
 39 













 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.

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

Collateral Agent, as applicable, shall not be obligated to, but may in its discretion, enter into any supplemental indenture or amendment that affects the Trustee’s and the Collateral Agent’s, as applicable, own rights, duties, liabilities

(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 or any amendments to the Security Documents or the Subordination Agreement with the Trustee and
the Collateral Agent, as applicable, 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 the provisions of any Security Document or the

 43 













 Upon the written request of the Company, and upon the filing with the Trustee and the
Collateral Agent, as applicable, of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee and the Collateral Agent, as applicable, shall join with the Company in the execution of such supplemental indenture
or any amendment to any Security Document or the Subordination Agreement unless such supplemental indenture or amendment affects the Trustee’s or Collateral Agent’s own rights, duties, liabilities or immunities under this Indenture, the
Security Documents, the Subordination Agreement or otherwise, in which case the Trustee or the Collateral Agent may in its discretion, but shall not be obligated to, enter into such supplemental indenture or amendment. 

Holders do not need under this Section 10.02 to approve the particular form of any proposed supplemental indenture or amendment. It shall
be sufficient if such Holders approve the substance thereof. After any such supplemental indenture or amendment becomes effective, the Company shall deliver to the Holders a notice briefly describing such supplemental indenture or amendment.
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 or amendment. 

Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture or amendment
pursuant to the provisions of this Article 10, this Indenture or the related Security Document or the Subordination Agreement 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 Collateral Agent, 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 or amendment shall be and be deemed to be part of the terms and conditions of this Indenture or amendment 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 shall so
determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed
by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 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 addition to the
documents required by Section 17.05, the Trustee and the Collateral Agent shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture or amendment executed pursuant hereto

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: 

  
 44 













 (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 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. 

  
 45 













 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. 
 ARTICLE 12 

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

ARTICLE 13 

[INTENTIONALLY OMITTED] 

ARTICLE 14 

CONVERSION OF NOTES 

Section 14.01. 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 0.4445 (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 independent 

  
 46 













 
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 (A) 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, (B) if the Company has failed to request the Bid Solicitation Agent to obtain bids when required or (C) 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 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 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:


  
 47 













 (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 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 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 

  
 48 













 
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, on and after July 1, 2020, but 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 a calendar quarter, but only during
that 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. 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. 

(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 (“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. The Trustee and
the Conversion Agent shall have no obligation to monitor the Conversion Limitation and shall have no liability for any conversions made by holders exceeding the Conversion Limitation. 

Section 14.02. [Intentionally Omitted]. 

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. 

  
 49 













 (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 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. 

  
 50 













 (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 (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. 
 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 

  
 51 













 
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. 

(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, 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 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 

  
 52 













 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. 
 (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 

  
 53 













 
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; 
 (ii) if the Stock Price is greater than $5.00 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 $0.8262 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. 

  
 54 













 Notwithstanding the foregoing, in no event shall the Applicable Conversion Rate per $1.00
principal amount of Notes exceed 1.21 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 Applicable Conversion Rate. The Applicable Conversion
Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Applicable Conversion Rate if Holders of the Notes participate (other than in the case of
(x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this
Section 14.05, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Applicable Conversion Rate, 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 Applicable Conversion Rate shall be adjusted based on the following formula: 
  
 



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

					
	CR’	  	=	  	the Applicable Conversion Rate 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 
  

					
	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 Applicable Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to
the Applicable Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

  
 55 













 (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 Applicable Conversion Rate shall be increased
based on the following formula: 
  
 



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

 

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

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

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

 Y = the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options
or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of
such rights, options or warrants. 
 Any increase made under this Section 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 Applicable Conversion Rate shall be decreased to the Applicable Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been
made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Applicable Conversion Rate shall be decreased to the Applicable Conversion Rate that would then
be in effect if such Ex-Dividend Date for such issuance had not occurred. 
 For purposes of this
Section 14.05(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. 

  
 56 













 (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 Applicable Conversion Rate shall be increased based on the following formula: 
  





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

 

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

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

 

					
	FMV	  	=	  	the fair market value (as determined 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 Applicable Conversion Rate shall be decreased to the Applicable Conversion Rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as
defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1.00 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 Applicable Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of
this Section 14.05(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. 

  
 57 













 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 Applicable Conversion Rate shall be increased based on the following formula: 

 
 



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

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

 FMV0 = the average of the Last Reported Sale Prices of
the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if
references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and 
 MP0 = the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period. 

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

  
 58 













 
no adjustment to the Applicable Conversion Rate 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 Applicable Conversion Rate 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 Applicable Conversion Rate 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 Applicable Conversion
Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Applicable Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may
be, as though it were a cash distribution, equal to the per share 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 Applicable Conversion Rate
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 Applicable Conversion Rate 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 Applicable Conversion
Rate 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 Applicable Conversion Rate shall
be adjusted based on the following formula: 

  
 59 













 



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

 

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

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

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

 Any increase 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 Applicable Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Applicable Conversion Rate that would then be in effect if such dividend
or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the
foregoing increase, each Holder of a Note shall receive, for each $1.00 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 Applicable Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. 

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

 
 



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

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


  
 60 














					
	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;

 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 Applicable Conversion Rate 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 Applicable Conversion
Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days
immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number
of Trading Days as have elapsed between the expiration date of such tender or exchange offer and such Trading Day in determining the Applicable Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the date such
tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph
and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer
expires to, and including, the last Trading Day of such Observation Period. 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 Applicable
Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the
related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 14.03(i) based on an adjusted Applicable Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Applicable Conversion Rate adjustment provisions in this Section 14.05, the Applicable Conversion Rate adjustment relating to such
Ex-Dividend Date shall not be made for such 

  
 61 













 
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 Applicable
Conversion Rate for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. 

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

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

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

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

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

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

(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 

  
 62 













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

  
 63 













 (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 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 

  
 64 













 
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. 
 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 

  
 65 













 
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: 

(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. 

  
 66 













 (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
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 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), 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 

  
 67 













 
Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15. 

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

(i) delivery to the Paying Agent 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. 
 (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 

  
 68 













 
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


  
 69 













 
instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case
may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
 Section 15.03.
Withdrawal of Fundamental Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent 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 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 

  
 70 













 
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. 
 ARTICLE 16 

COLLATERAL 

Section 16.01. Security Documents. 

The due and punctual payment of the principal of, premium and interest on the Notes when and as the same shall be due and payable, whether on
an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium and interest on the Notes and payment and performance of all other obligations of the Company, shall be
secured by a pledge of a perfected security interest in the Collateral in favor of the Collateral Agent on its behalf and on behalf of the Trustee and the Holders as provided in the Security Documents, which define the terms of the Liens that secure
the obligations of the Company, subject to the terms of the Subordination Agreement. The Trustee and the Company hereby acknowledge and agree that the Collateral Agent holds the Collateral in trust for the benefit of the Holders and pursuant to the
terms of the Security Documents and the Subordination Agreement. Each Holder, by accepting a Note, consents and agrees to the terms of the Security Documents (including the provisions providing for the possession, use, release and foreclosure of
Collateral) and the Subordination Agreement, in each case, as the same may be in effect or may be amended from time to time in accordance with their respective terms and this Indenture and the Subordination Agreement, and authorizes and directs the
Collateral Agent to enter into the Security Documents and the Subordination Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith. Subject to the Subordination Agreement, the Company shall deliver to the
Collateral Agent copies of all documents required to be filed pursuant to the Security Documents, and will do or cause to be done all such acts and things as may be reasonably required by the next sentence of this Section 16.01, to assure and
confirm to the Collateral Agent the security interest in the Collateral contemplated hereby, by the Security Documents or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this
Indenture and of the Notes secured hereby, according to the intent and purposes herein expressed. The Company shall take any and all actions and make all filings (including the filing of Uniform Commercial Code financing statements, continuation
statements and amendments thereto) required to cause the Security Documents to 

  
 71 













 
create and maintain, as security for the obligations of the Company, a valid and enforceable perfected (to the extent such security interest can be perfected by filing a UCC financing statement)
Lien and security interest in and on all of the Collateral (subject to the terms of the Subordination Agreement and the Security Documents), in favor of the Collateral Agent for the benefit of the Holders. 

Section 16.02. Release of Collateral. 

(a) Subject to Sections 16.02(b) and (c) hereof, the Liens securing the Notes will be automatically released, and the Trustee (subject to
its receipt of an Officers’ Certificate and Opinion of Counsel as provided below) shall execute documents evidencing such release, or instruct the Collateral Agent to execute, as applicable, the same at the Company’s sole cost and expense,
under one or more of the following circumstances: 
 (A) in whole, upon satisfaction and discharge of this Indenture as set
forth under Article 3; 
 (B) in part, as to any property or asset constituting Collateral: 

(1) that is sold or otherwise disposed of to a Person that is not the Company, or 

(2) otherwise in accordance with, and as expressly provided for under the Subordination Agreement; or 

(C) as described under Section 10.01. 

(b) With respect to any release of Collateral, upon receipt of an Officers’ Certificate and an Opinion of Counsel each stating that all
conditions precedent under this Indenture and the Security Documents and the Subordination Agreement, as applicable, to such release have been met and that it is proper for the Trustee or Collateral Agent to execute and deliver the documents
requested by the Company in connection with such release, and any necessary or proper instruments of termination, satisfaction, discharge or release prepared by the Company, the Trustee or Collateral Agent, as applicable, shall execute, deliver or
acknowledge (at the Company’s expense) such instruments or releases to evidence the release and discharge of any Collateral permitted to be released pursuant to this Indenture or the Security Documents or the Subordination Agreement. Neither
the Trustee nor the Collateral Agent shall be liable for any such release undertaken in reliance upon any such Officers’ Certificate or Opinion of Counsel, and, except as otherwise provided in the Subordination Agreement, the Trustee and the
Collateral Agent shall not be under any obligation to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction, discharge or termination, unless and until it receives such Officers’
Certificate and Opinion of Counsel. 
 (c) At any time when a Default or Event of Default has occurred and is continuing and the maturity of
the Notes has been accelerated (whether by declaration or otherwise), no release of Collateral pursuant to the provisions of this Indenture or the Security Documents shall be effective as against the Holders, except as otherwise provided in the
Subordination Agreement. 
 Section 16.03. Suits to Protect the Collateral. Subject to the provisions of Article 3 hereof, the
Security Documents and the Subordination Agreement, the Trustee, at the direction of Holders of a majority of the aggregate principal amount of the Notes outstanding, shall or shall direct the Collateral Agent to take all actions in order to: 

  
 72 













 (a) enforce any of the terms of the Security Documents and the Subordination Agreement; and

 (b) collect and receive any and all amounts payable in respect of the obligations of the Company hereunder. 

Subject to the provisions of the Security Documents and the Subordination Agreement, the Trustee and the Collateral Agent shall have power to
institute and to maintain such suits and proceedings to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Security Documents or this Indenture, and such suits and proceedings to preserve or
protect its interests and the interests of the Holders in the Collateral. Nothing in this Section 16.03 shall be considered to impose any such duty or obligation to act on the part of the Trustee or the Collateral Agent. 

Section 16.04. Authorization of Receipt of Funds by the Trustee Under the Collateral Documents. Subject to the provisions of the
Subordination Agreement, the Trustee is authorized to receive any funds for the benefit of the Holders distributed under the Security Documents, and to make further distributions of such funds to the Holders according to the provisions of this
Indenture. 
 Section 16.05. Purchaser Protected. In no event shall any purchaser in good faith of any property purported to be
released hereunder be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to
see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted by this Article 16 to be sold be under any obligation to ascertain or inquire
into the authority of the Company to make any such sale or other transfer. 
 Section 16.06. Powers Exercisable by Receiver or
Trustee. In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 16 upon the Company with respect to the release, sale or other disposition of such property may be
exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or of any Officer or Officers thereof required by the provisions of this Article 16;
and if the Trustee shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee. 

Section 16.07. [Reserved]. 

Section 16.08. Collateral Agent. (a) The Trustee and each of the Holders by acceptance of the Notes hereby designates and
appoints the Collateral Agent as its agent under this Indenture, the Security Documents and the Subordination Agreement and the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Collateral Agent to take
such action on its behalf under the provisions of this Indenture, the Security Documents and the Subordination Agreement and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this
Indenture, the Security Documents and the Subordination Agreement, and consents and agrees to the terms of the Subordination Agreement and each Security Document, as the same may be in effect or may be amended, restated, supplemented or otherwise
modified from time to time in accordance with their respective terms. The Collateral Agent agrees to act as such on the express conditions contained in this Section 16.08. The provisions of this Section 16.08 are solely for the benefit of
the Collateral Agent and none of the Trustee nor any of the Holders shall have any rights as a third party beneficiary of any of the provisions contained herein other than as expressly provided in Section 16.03. Each Holder agrees that any
action taken by the Collateral Agent in accordance with the provision of this Indenture, the Subordination Agreement and the Security Documents, and the exercise by the Collateral Agent of any 

  
 73 













 
rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture, the Security
Documents and the Subordination Agreement, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor
shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee or any Holder, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this
Indenture, the Security Documents and the Subordination Agreement or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to
the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship between independent contracting parties. 
 (b) The Collateral Agent may perform any of its
duties under this Indenture, the Security Documents or the Subordination Agreement by or through receivers, agents, employees, attorneys-in-fact or with respect to any
specified Person, such Person’s Affiliates, and the respective officers, directors, employees, agents, advisors and attorneys-in-fact of such Person and its
Affiliates (a “Related Person”), and shall be entitled to advice of counsel concerning all matters pertaining to such duties, and shall be entitled to act upon, and shall be fully protected in taking action in reliance upon any advice or
opinion given by legal counsel. The Collateral Agent shall not be responsible for the negligence or willful misconduct of any receiver, agent, employee, attorney-in-fact
or Related Person that it selects as long as such selection was made with due care. 
 (c) None of the Collateral Agent or any of its
respective Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful
misconduct) or under or in connection with any Security Document or the Subordination Agreement or the transactions contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of
the Trustee or any Holder for any recital, statement, representation, warranty, covenant or agreement made by the Company, or any Officer or Related Person thereof, contained in this Indenture or in any certificate, report, statement or other
document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture, the Security Documents or the Subordination Agreement, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Indenture, the Security Documents or the Subordination Agreement to perform its obligations hereunder or thereunder. The Collateral Agent shall not be liable for any amount in excess of the value of the Collateral. None of the
Collateral Agent or any of its respective Related Persons shall be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this
Indenture, the Security Documents or the Subordination Agreement. 
 (d) The Collateral Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication or document believed by it to be genuine and correct and to
have been signed, sent, or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel to the Company), independent accountants and other experts and advisors selected by the
Collateral Agent. The Collateral Agent 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. The Collateral Agent shall be fully justified in failing or refusing to take any action 

  
 74 













 
under this Indenture, the Security Documents or the Subordination Agreement unless it shall first have received indemnity or security satisfactory to it. Whenever reference is made in this
Indenture, the Security Documents or the Subordination Agreement to any action by, consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or
to be (or not to be) suffered or omitted by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the
Collateral Agent, it is understood that in all cases the Collateral Agent shall be fully justified in failing or refusing to take any such action under this Indenture if it shall not have received such advice or concurrence of the Trustee, acting at
the direction of the required Holders of the Notes (acting in accordance with the Indenture and other transaction documents, with such direction to be binding upon all of the Holders), as it deems appropriate. This provision is intended solely for
the benefit of the Collateral Agent and its successors and permitted assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto. 

(e) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless a
Responsible Officer of the Collateral Agent shall have received written notice from the Trustee or the Company referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default.”
The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 or the Holders of a majority in aggregate principal amount of the Securities (subject to
this Section 16.08 and the Subordination Agreement). 
 (f) The Collateral Agent may resign as Collateral Agent at any time upon at
least 60 day’s written notice to the Holders and Trustee (which may be extended up to 90 days upon reasonable request by the Company) and may be removed at any time with or without cause by the holders of a majority in the aggregate principal
amount of the outstanding Notes, with any such resignation or removal to become effective only upon the appointment of a successor Collateral Agent under this Section. If the Collateral Agent shall provide notice of its resignation or be removed as
Collateral Agent, then the holders of a majority in the aggregate principal amount of the outstanding Notes or the Company may (and if no such successor shall have been appointed within 45 days of the Collateral Agent’s date of notice of
resignation or removal, the Collateral Agent or the Company may) appoint a successor Collateral Agent which successor agent shall, in the case of any appointment by the Collateral Agent, be reasonably acceptable to the Holders of a majority in the
aggregate principal amount of the outstanding Notes, and the former Collateral Agent’s rights, powers and duties as Collateral Agent shall be terminated, without any other or further act or deed on the part of such former Collateral Agent
(except that the resigning Collateral Agent shall deliver all Collateral then in its possession to the successor Collateral Agent and shall execute and deliver to the successor Collateral Agent such instruments of assignment and transfer and other
similar documents as such successor Collateral Agent shall deem necessary or advisable. After any retiring Collateral Agent’s resignation or removal as Collateral Agent, the provisions of this Indenture and the Junior Lien Security Agreement
shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent. In the event that a successor Collateral Agent is not appointed within the time period specified in this Section following the provision
of a notice of resignation or removal of the Collateral Agent, the Collateral Agent, the Company representing at least 10% of the principal amount of the Notes may petition a court of competent jurisdiction for the appointment of a successor
Collateral Agent. In the event that the Collateral Agent is required to acquire title to an asset, or take any managerial action of any kind in regard thereto, in order to perform any obligation under any Security Document, which in the Collateral
Agent’s sole determination may cause the Collateral Agent to incur potential liability under any environmental law, the Collateral Agent reserves the right, instead of taking such action, to resign as the Agent. 

  
 75 













 (g) Except as otherwise explicitly provided herein or in the Security Documents or the
Subordination Agreement, neither the Collateral Agent nor any of its respective officers, directors, employees or agents or other Related Persons shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay
in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be
accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be responsible for any act or failure to act hereunder,
except for its own gross negligence or willful misconduct. 
 (h) The Collateral Agent is authorized and directed to (i) enter into the
Security Documents to which it is party, whether executed on or after the Issue Date, (ii) enter into the Subordination Agreement, (iii) make the representations of the Holders set forth in the Security Documents and Subordination
Agreement, (iv) bind the Holders on the terms as set forth in the Security Documents and the Subordination Agreement and (v) perform and observe its obligations under the Security Documents to which it is a party and the Subordination
Agreement. 
 (i) If at any time or times the Trustee shall receive (i) by payment, foreclosure, realization, set-off or otherwise, any proceeds of Collateral or any payments with respect to the obligations of the Company arising under, or relating to, this Indenture, except for any such proceeds or payments received by the
Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article 6, the Trustee shall promptly turn the same
over to the Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Collateral Agent such proceeds to be applied by the Collateral Agent pursuant to the terms of this Indenture, the Security Documents
and the Subordination Agreement. 
 (j) The Collateral Agent is each Holder’s agent for the purpose of perfecting the Holders’
security interest in assets which, in accordance with Article 9 of the Uniform Commercial Code can be perfected only by possession. Should the Trustee obtain possession of any such Collateral, upon request from the Company, the Trustee shall notify
the Collateral Agent thereof and promptly shall deliver such Collateral to the Collateral Agent or otherwise deal with such Collateral in accordance with the Collateral Agent’s instructions. 

(k) Neither the Trustee nor the Collateral Agent shall have any obligation whatsoever to the Trustee or any of the Holders to assure that the
Collateral exists or is owned by the Company or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or
enforced or are entitled to any particular priority, or to determine whether all of the Company’s property constituting collateral intended to be subject to the Lien and security interest of the Security Documents and the Subordination
Agreement has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability, ownership, transferability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or
under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture, any Security Document or the Subordination Agreement
other than pursuant to the instructions of the Trustee acting upon Holder direction or the Holders of a majority in aggregate principal amount of the Notes or as otherwise provided in the Security Documents or the Subordination Agreement, it being
understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent makes no representation or warranty and shall have no other duty or liability whatsoever to the Trustee or any Holder as to
any of the foregoing. 

  
 76 













 (l) If the Company or any Guarantor (i) incurs any obligations in respect of First Lien
Obligations at any time when no Subordination Agreement is in effect or at any time when Indebtedness constituting First Lien Obligations entitled to the benefit of an existing Subordination Agreement is concurrently retired, and (ii) delivers
to the Collateral Agent an Officers’ Certificate and Opinion of Counsel so stating (and confirming that the execution and delivery thereof complies with the terms of this Indenture) and requesting the Collateral Agent to enter into an
intercreditor agreement (on substantially the same terms as the Subordination Agreement) in favor of a designated agent or representative for the holders of the First Lien Obligations so incurred, the Collateral Agent shall (and is hereby authorized
and directed to) enter into such intercreditor agreement (at the sole expense and cost of the Company, including legal fees and expenses of the Collateral Agent and its counsel), bind the Holders on the terms set forth therein and perform and
observe its obligations thereunder. 
 (m) If the Company or any Guarantor incurs any obligations secured on a junior priority basis to the
Notes and delivers to the Collateral Agent an Officers’ Certificate and Opinion of Counsel so stating (and confirming that the execution and delivery thereof complies with the terms of this Indenture) and requesting the Collateral Agent to
enter into an intercreditor agreement (on terms that are customary for such financings as determined by the Company in good faith reflecting the subordination of such Liens to the Liens securing the obligations of the Company) in favor of a
designated agent or representative for the holders of the Indebtedness, which is secured on a junior priority basis to the obligations of the Company, so incurred, the Collateral Agent shall (and is hereby authorized and directed to) enter into such
intercreditor agreement (at the sole expense and cost of the Company, including legal fees and expenses of the Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations thereunder. 

(n) No provision of this Indenture, the Subordination Agreement or any Security Document shall require the Collateral Agent (or the Trustee) to
expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of
Holders (or the Trustee in the case of the Collateral Agent) if it shall not have received indemnity satisfactory to the Collateral Agent against potential costs and liabilities incurred by the Collateral Agent relating thereto. Notwithstanding
anything to the contrary contained in this Indenture, the Subordination Agreement or the Security Documents, in the event the Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies to acquire
title, control or possession of the Collateral, the Collateral Agent shall not be required to commence any such action or exercise any remedy or to inspect or conduct any studies of any property under the mortgages or take any such other action if
the Collateral Agent has determined that the Collateral Agent may incur personal liability as a result of the presence at, or release on or from, the Collateral or such property, of any hazardous substances unless the Collateral Agent has received
security or indemnity from the Holders in an amount and in a form all satisfactory to the Collateral Agent in its sole discretion, protecting the Collateral Agent from all such liability. The Collateral Agent shall at any time be entitled to cease
taking any action described in this paragraph (n) if it no longer reasonably deems any indemnity, security or undertaking from the Company or the Holders to be sufficient. 

(o) The Collateral Agent (i) shall not be liable for any action taken or omitted to be taken by it in connection with this Indenture, the
Subordination Agreement and the Security Documents or instrument referred to herein or therein, except to the extent that any of the foregoing are found by a final, non-appealable judgment of a court of
competent jurisdiction to have resulted from its own gross negligence or willful misconduct, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Company (and money held
in trust by the Collateral Agent need not be segregated from other funds except to the extent required by law) and (iii) may consult 

  
 77 













 
with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken,
omitted or suffered by it in good faith and in accordance with the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act. 

(p) Neither the Collateral Agent nor the Trustee shall be liable for delays or failures in performance resulting from acts beyond its control.
Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or
other disasters. Neither the Collateral Agent nor the Trustee shall be liable for any indirect, special, punitive, incidental or consequential damages (included but not limited to lost profits) whatsoever, even if it has been informed of the
likelihood thereof and regardless of the form of action. 
 (q) The Collateral Agent does not assume any responsibility for any failure or
delay in performance or any breach by the Company under this Indenture, the Subordination Agreement and the Security Documents. The Collateral Agent shall not be responsible to the Holders or any other Person for any recitals, statements,
information, representations or warranties contained in this Indenture, the Subordination Agreement or any Security Document or in any certificate, report, statement, or other document referred to or provided for in, or received by the Collateral
Agent under or in connection with, this Indenture, the Subordination Agreement or any Security Document; the execution, validity, genuineness, effectiveness or enforceability of the Subordination Agreement and any Security Documents of any other
party thereto; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral, or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority of any Lien therein; the
validity, enforceability or collectability of any obligations of the Company; the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any obligor; or for any failure of any obligor to
perform its Obligations under this Indenture, the Subordination Agreement and the Security Documents. The Collateral Agent shall have no obligation to any Holder or any other Person to ascertain or inquire into the existence of any Default or Event
of Default, the observance or performance by any obligor of any terms of this Indenture, the Subordination Agreement and the Security Documents, or the satisfaction of any conditions precedent contained in this Indenture, the Subordination Agreement
and any Security Documents. The Collateral Agent shall not be required to initiate or conduct any litigation or collection or other proceeding under this Indenture, the Subordination Agreement and the Security Documents unless expressly set forth
hereunder or thereunder. The Collateral Agent shall have the right at any time to seek instructions from the Holders with respect to the administration of the Security Documents and the Subordination Agreement. 

(r) The parties hereto and the Holders hereby agree and acknowledge that the Collateral Agent shall not assume, be responsible for or otherwise
be obligated for any liabilities, claims, causes of action, suits, losses, allegations, requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs (including but not limited to,
any remediation, corrective action, response, removal or remedial action, or investigation, operations and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, pursuant to any
environmental law as a result of this Indenture, the Subordination Agreement, the Security Documents or any actions taken pursuant hereto or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that in the exercise of
its rights under this Indenture, the Subordination Agreement and the Security Documents, the Collateral Agent may hold or obtain indicia of ownership primarily to protect the security interest of the Collateral Agent in the Collateral and that any
such actions taken by the Collateral Agent shall not be construed as or otherwise constitute any participation in the management of such Collateral. 

  
 78 













 (s) Upon the receipt by the Collateral Agent of a written request of the Company signed by
one Officer of the Company (a “Security Document Order”), the Collateral Agent is hereby authorized to execute and enter into, and shall execute and enter into, without the further consent of any Holder or the Trustee, any Security
Document in form satisfactory to the Collateral Agent to be executed after the Issue Date. Such Security Document Order shall (i) state that it is being delivered to the Collateral Agent pursuant to, and is a Security Document Order referred to
in, this Section 12.08(s), and (ii) instruct the Collateral Agent to execute and enter into such Security Document. Any such execution of a Security Document shall be at the direction and expense of the Company, upon delivery to the
Collateral Agent of an Officers’ Certificate and Opinion of Counsel stating that all conditions precedent to the execution and delivery of the Security Document have been satisfied. The Holders, by their acceptance of the Securities, hereby
authorize and direct the Collateral Agent to execute such Security Documents. The Collateral Agent shall have no liability with respect to signing such document presented to it in accordance with this paragraph. 

(t) Subject to the provisions of the applicable Security Documents and the Subordination Agreement, each Holder, by acceptance of the Notes,
agrees that the Collateral Agent shall execute and deliver the Subordination Agreement and the Security Documents to which it is a party and all agreements, documents and instruments incidental thereto, and act in accordance with the terms thereof.
For the avoidance of doubt, the Collateral Agent shall have no discretion under this Indenture, the Subordination Agreement or the Security Documents and shall not be required to make or give any determination, consent, approval, request or
direction without the written direction of the Holders of a majority in aggregate principal amount of the then outstanding Notes or the Trustee (acting at the direction of such majority), as applicable. 

(u) After the occurrence of an Event of Default, the Trustee (acting at the direction of Holders of a majority in aggregate principal amount of
Notes outstanding) shall direct the Collateral Agent in connection with any action required or permitted by this Indenture, the Security Documents or the Subordination Agreement. 

(v) The Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed under the

the provisions of Section 6.10 hereof and the other provisions of this Indenture. 
 (w) Subject to the terms of the Security Documents
and the Subordination Agreement, in each case that the Collateral Agent may or is required hereunder or under any other Notes Documentation to take any action (an “Action”), including without limitation to make any determination, to give
consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any other Security Documents or the Subordination Agreement, the Collateral Agent will only do so upon direction and receiving
indemnity satisfactory to it from the Holders of a majority in aggregate principal amount of the then outstanding Notes. The Collateral Agent shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with the
direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. Subject to the terms of the Security Documents and the Subordination Agreement, until the Collateral Agent receives direction from the Holders of a
majority in aggregate principal amount of the then outstanding Notes with respect to any Action, the Collateral Agent shall be entitled to refrain from such Action unless and until the Collateral Agent shall have received direction from the Holders
of a majority in aggregate principal amount of the then outstanding Notes, and the Collateral Agent shall not incur liability to any Person by reason of so refraining.

Collateral Agent or the Trustee be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture
(including without limitation the filing or continuation of any Uniform Commercial Code financing or continuation statements or similar documents or instruments), nor shall the Collateral Agent or the Trustee be responsible for, and neither the
Collateral Agent nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Security Documents or the Subordination Agreement or the security interests or Liens intended to be created thereby. 

(y) Before the Collateral Agent acts or refrains from acting in each case at the request or direction of the Company, it may require an
Officers’ Certificate and an Opinion of Counsel, which shall conform to the provisions of Section 17.05. The Collateral Agent shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or
opinion. 
 (z) Notwithstanding anything to the contrary contained herein, the Collateral Agent shall act pursuant to the instructions of the
Holders and the Trustee solely with respect to the Security Documents, the Subordination Agreement and the Collateral.

Collateral Agent determines adversely affects it or otherwise subjects it to personal liability, including without limitation agreements to indemnify any contractual counterparty.

 82 













 
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

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

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. 
 If an authenticating agent is appointed pursuant to this Section 17.10, the Notes may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
  

	
	                            ,
	 as Authenticating Agent, certifies that this is one of the Notes described

the exhibits hereto set forth the entire agreement and understanding of the parties related to this transaction and supersedes all prior agreements and understandings, oral or written. 

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 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 

  
 84 













 
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% Voluntary
Convertible Senior Secured Note due 2024 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 5.0%
Voluntary Convertible Senior Secured 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 February [__], 2020 (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. 
 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 

  
 A-5 













 
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.

CASH PAYMENT INSTRUCTIONS 

  
 2 













 The undersigned directs that any cash payment owed for fractional shares (and, if
applicable, for any accrued but unpaid interest which may be payable under certain limited circumstances) be wired in accordance with the wire instructions set forth below: 

Bank:    ___________________________________________ 

Address: _________________________________________ 
 Name of
Account: ________________________________ 
 ABA No.: ________________________________________ 

Account No.: _____________________________________ 
 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.
