This Amendment of Investor Rights Agreement (this “Amendment”) is entered into and made effective as of the 6th day of December, 2013 (the “Effective Date”), by and among RiceBran Technologies (f/k/a NutraCea), a California corporation (“RBT”), AF Bran Holdings-NL LLC (“AFBH-NL”) and AF Bran Holdings LLC (“AFBH”), in each case, a Delaware limited liability company (AFBH-NL and AFBH being referred to collectively as “AF” or “Investor”), Industria Riograndese de Oleos Vegetais Ltda, a limited liability company organized under the laws of the Federative Republic of Brazil  (“Irgovel”) and Nutra SA, LLC, a Delaware limited liability company (the “Company”).  The Company, RBT, Irgovel and Investor are sometimes referred herein collectively as the “Parties.”

WHEREAS, the Parties have entered into various agreements regarding AF’s investments into the Company and the operation and control of the Company and Irgovel (collectively the “Investment Agreements”), including but not limited to (i) an Investor Rights Agreement (the “IRA”) dated as of December 29, 2010, (ii) a Membership Interest Purchase Agreement (the “MIPA”) dated as of December 29, 2010 (as amended on January 18, 2011 and as further amended pursuant to the Amendment of Investment Agreements dated October 31, 2013), and (iii) a Second Amended and Restated Limited Liability Company Agreement for Nutra SA, LLC dated as of December 24, 2012 (as amended pursuant to the Amendment of Investment Agreements);

WHEREAS, the Parties desire to amend the IRA to delete and terminate Section 5 (Conversion Rights) and Section 6 (Roll Up Rights) of the IRA and to waive any associated rights or obligations under either or both Sections;

NOW, THEREFORE, in consideration of the foregoing premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

1.             Amendment to IRA; Waiver.

(a)            Section 5 (Conversion Rights). Section 5 (Conversion Rights) of the IRA is hereby deleted in its entirety and all rights of AF thereunder (“Conversion Rights”) are terminated and shall have no further force or effect. Without limiting the foregoing, AF specifically waives and releases any existing rights it may have to exercise any such Conversion Rights.

(b)            Section 6 (Roll Up Rights). Section 6 (Roll Up Rights) of the IRA is hereby deleted in its entirety and all rights of AF thereunder (“Roll Up Rights”) are terminated and shall have no further force or effect. Without limiting the foregoing, AF specifically waives and releases any existing rights it may have to exercise any such Roll Up Rights.

(c)            Investment Agreements. AF agrees and acknowledges that the termination of the Conversion Rights and Roll Up Rights as set forth herein shall supersede and amend any and all corresponding provisions of the Investment Agreements establishing a right of AF to exchange Units (as defined in the MIPA) of Investor in the Company for stock or membership interests in any current or future affiliates of RBT or any Global Holding Company (as defined in the IRA).

2.             No Further Amendment.  The Parties acknowledge and agree that there are no other amendments, changes, waivers or modifications to the IRA or other Investment Agreements other than as set forth in this Amendment, and all other terms of the Investment Agreements remain in full force and effect except as expressly modified or waived herein.  The Parties agree that except as expressly set forth herein, this Amendment shall not be construed as a waiver by any Party of any of its other rights or obligations under the Investment Agreements.

3.             Counterparts.  This Amendment may be executed in any number of counterparts with the same effect as if the Parties had all signed the same document.  All counterparts shall be construed together and shall constitute one agreement. This Amendment, to the extent executed and delivered by means of a photographic, photostatic, facsimile or similar reproduction of such signed writing using a facsimile machine or electronic mail shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.  At the request of any Party or to any such agreement or instrument, each other Party or party thereto shall re execute original forms thereof and deliver them to all other Parties.  No Party shall raise the use of a facsimile machine or electronic mail to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or electronic mail as a defense to the formation or enforceability of a contract and each such Party forever waives any such defense.

4.             Headings.  The article and section headings of this Amendment are for convenience of reference only and shall not be deemed to alter or affect the meaning or interpretation of any provision hereof.

5.             Effectiveness.  This Amendment shall be effective and binding upon all parties to the Investment Agreements upon the written consent of the Parties.

6.             Entire Agreement.  This Amendment constitutes the entire agreement among the Parties with respect to the amendment and waiver of the Investment Agreements with respect to the subject matter hereof.

                                (i)           
The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor
Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall
be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed
to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee
of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements
satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company
shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than
10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of
the proposed payment. The Company shall promptly notify the Trustee of such special record date and the Trustee, in the name and
at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date
therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in the Note Register, not less
than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record
date therefor having been so mailed, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant
to the following clause (ii) of this Section 2.05(c).

 

                                (ii)           
The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements
of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon
such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee
of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.06. Execution, Authentication
and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature
of its Chief Executive Officer, President, Chief Financial Officer, Treasurer, Secretary or any of its Executive or Senior Vice
Presidents.

 

At any time and from time to time after
the execution and delivery of this Supplemental Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance
with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder.

 

Only such Notes as shall bear thereon a
certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually
or by facsimile by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section
2.10 of the Base Indenture), shall be entitled to the benefits of the Indenture or be valid or obligatory for any purpose.
Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence
that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits
of the Indenture.

 

In case any Officer of the Company who
shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and
delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed
of as though the person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on
behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company,
although at the date of the execution of this Supplemental Indenture any such person was not such an Officer.

 

Section 2.07. Exchange and Registration
of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office
a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section
4.02 of the Base Indenture, the “Note Register”) in which, subject to such reasonable regulations as
it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in
written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby
initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein
provided. The Company may appoint one or more co-Note Registrars in accordance with Section
4.02 of the Base Indenture.

 

    	17

    	 

    

 

Upon surrender for registration of transfer
of any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in
this Section 2.07, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such
restrictive legends as may be required by the Indenture.

 

Notes may be exchanged for other Notes
of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such
office or agency maintained by the Company pursuant to Section 4.02 of
the Base Indenture. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not
contemporaneously outstanding.

 

All Notes presented or surrendered for
registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note
Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in
form satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

 

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

 

None of the Company, the Trustee, the Note
Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion
or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any Notes, or
a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15
or (iii) any Notes, or a portion of any Note, selected for redemption in accordance with Article 16.

 

All Notes issued upon any registration
of transfer or exchange of Notes in accordance with the Indenture shall be the valid obligations of the Company, evidencing the
same debt, and entitled to the same benefits under the 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 2.07(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 the Indenture (including the
restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

 

    	18

    	 

    

 

(c)           
Notwithstanding any other provisions of the Indenture (other than the provisions set forth in this Section 2.07(c)), a
Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee
of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form
made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written
notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in
compliance with this Section 2.07(c).

 

The Depositary shall be a clearing agency
registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect
to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co.,
as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

 

If (i) the Depositary notifies the Company
at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary
is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a
successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is
continuing and a beneficial owner of any Note requests that its beneficial interest therein be 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 2.07(c) shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in
whose names such Physical Notes are so registered.

 

At such time as all interests in a Global
Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the
Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time
prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased
or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part
of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions
existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement
shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction
or increase.

 

    	19

    	 

    

 

None of the Company, the Trustee 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.

 

(d)           
Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate
of the Company (or any Person who was an Affiliate of the Company at any time during the three months preceding) may not be resold
by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption
from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case
may be, no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). 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
2.10.

 

Section 2.08. Mutilated, Destroyed, Lost
or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may
execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver,
a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note,
or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note
shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may
be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable,
to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership
thereof.

 

The Trustee or such authenticating agent
may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee,
the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the
Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company
may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection
therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the
old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has
been surrendered for required repurchase or is about to be converted in accordance with Article 14 shall become mutilated or be
destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the
payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note),
as the case may be, if the applicant for such 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.

 

    	20

    	 

    

 

Every substitute Note issued pursuant to
the provisions of this Section 2.08 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) the 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, redemption, 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, redemption, conversion
or repurchase of negotiable instruments or other securities without their surrender.

 

Section 2.09. 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 of the Base Indenture and
the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate
principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor.
Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations
under the Indenture as Physical Notes authenticated and delivered hereunder.

 

Section 2.10. Cancellation of Notes Paid,
Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, redemption, 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 controlled Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee
shall be canceled promptly by it, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any
of the provisions of the Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and,
after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request
in a Company Order.

 

    	21

    	 

    

 

Section 2.11. 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 2.12. Additional Notes; Repurchases.
The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen the Indenture and issue additional
Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue price and interest
accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any
such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional
Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the
Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion
of Counsel to cover such matters, in addition to those required by Section
13.07 of the Base Indenture, as the Trustee shall reasonably request; provided, however, that for the avoidance of doubt,
nothing herein shall impose an obligation on the Trustee to so require such documents to cover any additional matters. 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 2.10.

Satisfaction and Discharge

 

Section 3.01. Satisfaction and Discharge.
Article XI of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth in this Section 3.01 shall, with
respect to the Notes, supersede in its entirety Article XI of the Base Indenture, and all references in the Base Indenture to Article
XI thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this
Section 3.01 and the applicable provisions set forth in this Section 3.01, respectively. The Indenture shall upon request of the
Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when (a) (i) all Notes theretofore
authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid
as provided in Section 2.08 and (y) Notes for whose payment money has theretofore been deposited in trust or segregated and held
in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.01(d)) have
been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as
applicable, after the Notes have become due and payable, whether on the Maturity Date, any Redemption 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 the Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and
an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge
of the Indenture have been complied with. Notwithstanding the satisfaction and discharge of the Indenture, the obligations of the
Company to the Trustee under Section 7.07 of the Base Indenture shall survive.

Particular Covenants of the Company

 

Section 4.01. Provisions as to Paying
Agent. This Section 4.01 shall supersede Section 4.03 of the Base
Indenture, and any reference in the Base Indenture to Section 4.03 thereof shall be deemed to refer instead to this  Section
4.01.  (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 4.01:

 

                                 (i)           
that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and
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 Redemption Price and 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 Redemption Price and 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 Redemption
Price and 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.

 

    	23

    	 

    

 

(b)           
If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption
Price and 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
Redemption Price and 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 Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and
unpaid interest on, the Notes when the same shall become due and payable.

 

(c)           
Anything in this Section 4.01 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining
a satisfaction and discharge of the 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 4.01, such sums or amounts to
be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to
the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums
or amounts.

 

(d)           
Any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by the Company, in trust
for the payment of the principal (including the Redemption Price and 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 Redemption Price and 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 shares of Common Stock, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such
money and shares of Common Stock remain unclaimed and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money and shares of Common Stock then remaining will be repaid
or delivered to the Company.

Section 4.02. Existence. Subject
to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence.

 

Section 4.03. Reports. (a) The Company
shall file with the Trustee, within 15 days after the same are required to be filed with the Commission, copies of any documents
or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving
effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files
with the Commission via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section
4.03 at the time such documents are filed via the EDGAR system.

 

(b)           
Delivery of the reports and documents described in subsection Section 4.03 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).

 

Section 4.04. 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 the 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 4.05. Compliance Certificate;
Statements as to Defaults. In addition to Section 4.06 of the Base Indenture, 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 4.06. Further Instruments and
Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as
may be reasonably necessary or proper to carry out more effectively the purposes of the Indenture.

Defaults and Remedies

 

Section 6.01. Applicability of Article
VI of the Base Indenture. Article VI of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth
in this Article 6 shall, with respect to the Notes, supersede in its entirety Article VI of the Base Indenture, and all references
in the Base Indenture to Article VI thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be
deemed to be references to this Article 6 and the applicable provisions set forth in this Article 6, respectively.

 

Section 6.02. Events of Default.
Each of the following events shall be an “Event of Default” with respect to the Notes:

 

(a)

Section 6.03. 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 6.02(i) or Section 6.02(j) with respect to the Company or any of
its Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, 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 of the Base Indenture, 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 the Indenture or in the Notes
to the contrary notwithstanding. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company
or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if
any, on, all Notes shall become and shall automatically be immediately due and payable.

 

    	27

    	 

    

 

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 plus one percent at such time) and amounts due to the Trustee pursuant
to Section 7.07 of the Base Indenture, 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
the 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, waived or otherwise remedied pursuant to Section 6.10, then and
in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal
amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of
Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the 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 Redemption
Price and 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 6.04. Additional Interest.
Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for
an Event of Default relating to (i) the failure by the Company to file with the Trustee pursuant to Section 314(a)(1) of the Trust
Indenture Act any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in Section 4.03
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 (a) 0.25% per annum of the principal amount of the Notes outstanding for the first 90 days of the 180-day
period during which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default
first occurs and (b) 0.50% per annum of the principal amount of the Notes outstanding for the last 90 days of such 180-day period
as long as such Event of Default is continuing. 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 181st day after such Event of Default (if the
Event of Default relating to the Company’s failure to file is not cured or waived prior to such 181st day), the Notes shall
be immediately subject to acceleration as provided in Section 6.03. In the event the Company does not elect to pay Additional Interest
following an Event of Default in accordance with this Section 6.04 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 6.03.

 

    	28

    	 

    

 

In order to elect to pay Additional Interest
as the sole remedy during the first 180 days after the occurrence of any Event of Default described in the immediately preceding
paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning
of such 180-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as
provided in Section 6.03.

 

Section 6.05. 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 plus one percent at such time, and, in addition thereto, such further amount as shall be sufficient to cover
any amounts due to the Trustee under Section 7.07 of the Base Indenture.
If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express
trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment
or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged
or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes,
wherever situated.

 

In the event there shall be pending proceedings
for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States
Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator
or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the
Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor
upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the
principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand pursuant to the provisions of this Section 6.05, 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
7.07 of the Base Indenture; 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 7.07 of the Base Indenture,
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.

 

    	29

    	 

    

 

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 the 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 the 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 the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver
pursuant to Section 6.10 or any rescission and annulment pursuant to Section 6.03 or for any other reason or shall have been determined
adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination
in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers
of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

 

Section 6.06. Application of Monies Collected
by Trustee. Any monies collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the
following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several
Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

 

    	30

    	 

    

 

First, to the payment of all amounts
due the Trustee under Section 7.07 of the Base Indenture;

 

Second, in case the principal of
the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion
of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case
may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate
borne by the Notes at such time, 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 Redemption Price and 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 Redemption Price and 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 Redemption Price and 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 6.07. Proceedings by Holders.
Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price and 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 the Indenture to institute any suit,
action or proceeding in equity or at law upon or under or with respect to the 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 Holders shall have offered to the Trustee such security or indemnity reasonably satisfactory to it against any loss,
liability or expense to be incurred therein or thereby;

 

    	31

    	 

    

 

(d)           
the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused
to institute any such action, suit or proceeding; and

 

(e)           
no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the
Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period
pursuant to Section 6.10,

 

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 the 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 the 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 6.07, 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
the Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x)
the principal (including the Redemption Price and 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 the Indenture, or to institute suit for the enforcement of any such payment or delivery,
as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent
of such Holder.

 

Section 6.08. Proceedings by Trustee.
In case of an Event of Default, the Trustee may in its discretion (and subject to the provisions of Sections 7.01 and 7.07 of the
Base Indenture) proceed to protect and enforce the rights vested in it by the 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 the Indenture or in aid of the exercise
of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture
or by law.

 

Section 6.09. Remedies Cumulative and
Continuing. Except as provided in the last paragraph of Section 2.08, 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 the 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 6.07, 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.

 

    	32

    	 

    

 

Section 6.10. Direction of Proceedings
and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of the Notes at
the time outstanding determined in accordance with Section 8.04 of the
Base Indenture 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 the Indenture, (b) the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such direction, and (c) the Trustee may demand security or indemnity
reasonably satisfactory to it in accordance with Sections 7.01 and 7.03 of the Base Indenture. The Trustee may refuse to follow
any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal
liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance
with Section 8.04 of the Base Indenture 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 Redemption Price and 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 6.10,
said Default or Event of Default shall for all purposes of the Notes and the 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 6.11. Notice of Defaults.
The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge,
mail to all Holders as the names and addresses of such Holders appear upon the Note Register, notice of all Defaults known to a
Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that,
except in the case of a Default in the payment of the principal of (including the Redemption Price and 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 committee of Responsible Officers
of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

 

Section 6.12. Undertaking to Pay Costs.
All parties to the 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 the 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 6.12 (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 of the Base Indenture, 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 Redemption Price and 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 in accordance with the provisions of Article 14.

the aggregate principal amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting may
be held as so adjourned without further notice.

 

Section 9.06. Voting. The vote upon
any resolution submitted to any meeting of Holders shall be by written ballot on which shall be subscribed the signatures of the
Holders or of their representatives by proxy and the outstanding aggregate principal amount of the Notes held or represented by
them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting
for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate
of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote
by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice
of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the aggregate principal
amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of
the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to
the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

 

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

 

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

Section 10.01. Supplemental Indentures
Without Consent of Holders. This Section 10.01 shall supersede Section
9.01 of the Base Indenture, and any reference in the Base Indenture to Section 9.01 thereof shall be deemed to refer instead to
this  Section 10.01.  The Company and the Trustee, at the
Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for one
or more of the following purposes:

 

(a)          
to cure any ambiguity, omission, defect or inconsistency that does not adversely affect Holders of the Notes;

 

(b)          
to provide for the assumption by a Successor Company of the obligations of the Company under the Indenture pursuant to
Article 11;

 

(c)          
to add guarantees with respect to the Notes;

 

(d)          
to secure the Notes;

 

(e)          
to add to the covenants or Events of Default of the Company for the benefit of the Holders or surrender any right or power

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

 

(h)          
to conform the provisions of the Indenture or the Notes to the “Description of notes” section of the Prospectus
Supplement; or

 

(i)           
evidence and provide for the appointment under the Indenture of a successor trustee.

 

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

 

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

 

Section 10.02. Supplemental Indentures
with Consent of Holders. This Section 10.02 shall supersede Section
9.02 of the Base Indenture, and any reference in the Base Indenture to Section 9.02 thereof shall be deemed to refer instead to
this  Section 10.02. With the consent (evidenced as provided
in Article VIII of the Base Indenture) of the Holders of at least
a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article
VIII of the Base Indenture and including, without limitation, consents obtained in connection with a repurchase of, or tender
or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors, and the Trustee, at the
Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or any supplemental
indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the consent of
each Holder of an outstanding Note affected, no such supplemental indenture shall:

 

    	37

    	 

    

 

(a)           
reduce the amount of Notes whose Holders must consent to an amendment;

 

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

 

(c)

(e)           
reduce the Redemption Price or the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse
to the Holders the Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the
covenants, definitions or otherwise;

 

(f)           
make any Note payable in a currency, or at a place of payment, other than that stated in the Note;

 

(g)           
comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture
Act;

 

(h)           
change the ranking of the Notes;

 

(i)           
impair the right of any Holder to receive payment of principal and interest on such Holder’s Notes on or after the
due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes; or

 

(j)           
make any change in this Article 10 that requires each Holder’s consent or in the waiver provisions in Section 6.03
or Section 6.10.

 

Upon the written request of the Company,
and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section
9.05 of the Base Indenture, the Trustee shall join with the Company in the execution of such supplemental indenture unless
such supplemental indenture affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in
which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

 

    	38

    	 

    

 

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

Consolidation, Merger, Sale, Conveyance and Lease

 

Section 11.01. Applicability of Article
X of the Base Indenture. Article X of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth in
this Article 11 shall, with respect to the Notes, supersede in its entirety Article X of the Base Indenture, and all references
in the Base Indenture to Article X thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be
deemed to be references to this Article 11 and the applicable provisions set forth in this Article 11, respectively. In addition,
Section 4.05 of the Base Indenture shall be deemed deleted with respect to the Notes.

 

Section 11.02. Company May Consolidate,
Etc. on Certain Terms. Subject to the provisions of Section 11.03, the Company shall not consolidate with, merge with or into,
or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless:

 

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

 

(b)           
immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing
under the 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 11.03. Successor Corporation
to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by
the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee,
of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes, the due and punctual delivery
or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all
of the covenants and conditions of the 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 the 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 the Indenture as the Notes theretofore or thereafter issued in accordance
with the terms of the 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 Supplemental 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 the Indenture and the Notes.

 

    	39

    	 

    

 

In case of any such consolidation, merger,
sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter
to be issued as may be appropriate.

 

Section 11.04. Opinion of Counsel to
Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee
shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such
transaction, such supplemental indenture, complies with the provisions of this Article 11.

Conversion of Notes

 

Section 14.01. Conversion Privilege.
(a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right, at such
Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral
multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 14.01(b), at any time prior to
the close of business on the Business Day immediately preceding June 15, 2020 under the circumstances and during the periods set
forth in Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), at any time on or after June 15,
2020 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 66.0262 shares of Common Stock (subject to adjustment as provided in this
Article 14, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance
with, the settlement provisions of Section 14.02, the “Conversion Obligation”).

 

(b)           
(i) Prior to the close of business on the Business Day immediately preceding June 15, 2020, a Holder may surrender all
or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive
Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes,
as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the
Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate
on each such Trading Day. 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 Supplemental Indenture. The Company shall provide written notice to the
Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company pursuant to the
definition of Trading Price, along with appropriate contact information for each. 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 and provided
the Bid Solicitation Agent with the names of at least three nationally recognized securities 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 would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion
Rate, at which time the Company shall instruct the Bid Solicitation Agent 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 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 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
Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company
shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading
Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal
to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall
so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee).

(ii)           
If, prior to the close of business on the Business Day immediately preceding June 15, 2020, the Company elects to:

 

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

 

                                                                   (B)           
distribute to all or substantially all holders of the Common Stock the Company’s assets, securities or rights to purchase
securities of the Company (excluding for this purpose a distribution solely in the form of cash required to preserve the Company’s
status as a REIT), which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10%
of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution,

 

then, in either case, the Company shall notify all Holders of
the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 30 Scheduled Trading Days prior to the Ex-Dividend
Date for such issuance or distribution. Once the Company has given such notice, a Holder may surrender all or any portion of its
Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend
Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take
place, in each case, even if the Notes are not otherwise convertible at such time.

 

                                                
(iii)           
If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close
of business on the Business Day immediately preceding June 15, 2020, regardless of whether a Holder has the right to require the
Company to repurchase the Notes pursuant to Section 15.02, or if the Company is a party to a consolidation, merger, binding share
exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the Common Stock would
be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion
at any time from or after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction
(or, if later, the Business Day after the Company gives notice of such transaction) until 35 Trading Days after the actual effective
date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase
Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable
following the date the Company publicly announces such transaction but in no event less than 30 Scheduled Trading Days prior to
the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of such transaction at least
30 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.

(iv)           
Prior to the close of business on the Business Day immediately preceding June 15, 2020, a Holder may surrender all or any
portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on December
31, 2013 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days
(whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately
preceding calendar quarter (as reported to the Conversion Agent by the Company) is greater than or equal to 130% of the Conversion
Price on each applicable Trading Day. Upon receipt of and on the basis of such report from the Company, the Conversion Agent, on
behalf of the Company, shall determine at the beginning of each calendar quarter commencing after December 31, 2013 whether the
Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Company and the Trustee if the
Notes become convertible in accordance with this clause (iv).

 

                                                  
(v)           
If the Company calls any or all of the Notes for redemption pursuant to Article 16 prior to the close of business on the
Business Day immediately preceding June 15, 2020, then a Holder may surrender all or any portion of its Notes for conversion at
any time prior to the close of business on the Scheduled Trading Day prior to the Redemption Date, even if the Notes are not otherwise
convertible at such time. After that time, the right to convert shall expire, unless the Company defaults in the payment of the
Redemption Price, in which case a Holder of Notes may convert its Notes until the Redemption Price has been paid or duly provided
for.

 

Section 14.02. Conversion Procedure;
Settlement Upon Conversion.

 

    	43

    	 

    

 

(a)           
Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall pay
or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted,
cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering
any fractional share of Common Stock in accordance with subsection (j) of this Section 14.02 (“Physical Settlement”)
or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share
of Common Stock in accordance with subsection (j) of this Section 14.02 (“Combination Settlement”), at its
election, as set forth in this Section 14.02.

 

                                                 (i)           
All conversions for which the relevant Conversion Date occurs on or after June 15, 2020, and all conversions for which the
relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to
the related Redemption Date, shall be settled using the same Settlement Method.

 

                                                 (ii)           
Except for any conversions for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption
Notice with respect to the Notes but prior to the related Redemption Date, and any conversions for which the relevant Conversion
Date occurs on or after June 15, 2020, 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, through the Trustee, shall deliver
such Settlement Notice to converting Holders no later than the close of business on the Trading Day immediately following the relevant
Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs (x) subject to clause (y), after
the date of issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date, in such Redemption
Notice or (y) on or after June 15, 2020, no later than June 15, 2020). 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 $1,000 principal amount of Notes shall be equal to $1,000. Such Settlement Notice shall specify
the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate
the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination
Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount
of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000.

 

    	44

    	 

    

 

                                                
(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 (or cause its stock transfer agent to deliver) to the converting Holder in respect of each $1,000 principal amount
of Notes being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date;

 

                                                                   (B)           
if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company
shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal
to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Observation Period; and

 

                                                                   (C)           
if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion
by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of
Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading
Days during the related Observation Period.

 

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

 

(b)           
Subject to Section 14.02(e), before any Holder of a Note
shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures
of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date
to which such Holder is not entitled as set forth in Section 14.02(h) and (ii) in the case of a Physical Note (1) complete, manually
sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile
thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the
principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or
certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2)
surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents),
at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required,
pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section
14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article
14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder
thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has
not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03.

 

    	45

    	 

    

 

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 provided in Section
14.03 and Section 14.07 below, the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion
Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement,
or on the third Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement
Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued by its stock
transfer agent, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates
or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled
in satisfaction of the Company’s Conversion Obligation. Prior to the issuance of Common Stock, the Company shall give the
Conversion Agent notice of the number of shares of Common Stock being so issued and the method by which the issuance shall take
place. Any required funds due to a converting Holder in connection with a Cash Settlement or Combination Settlement shall be delivered
to the Paying Agent. For the avoidance of doubt, neither the Conversion Agent nor the Trustee shall have any responsibility for
the issuance by the Company of shares of Common Stock.

 

(d)           
In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate
and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations
in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge
by the converting Holder but, if required by the Company or Trustee, with payment by the converting Holder of a sum sufficient
to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be
imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different
from the name of the Holder of the old Notes surrendered for such conversion.

 

    	46

    	 

    

 

(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 Company (or if the
stock certificates are delivered by the Company to the Conversion Agent for further delivery to the converting Holder, the Conversion
Agent) may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s
name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately
preceding sentence.

 

(f)           
Except as provided in Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon
the conversion of any Note.

 

(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 on the corresponding Interest
Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on
any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds
equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1)
for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a
Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; (3) if the Company
has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately
following the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist
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 regardless
of whether their Notes have been converted following such Regular Record Date.

 

    	47

    	 

    

 

(i)           
The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be
treated as a stockholder of record as of the close of business on the relevant Conversion Date (if the Company elects to satisfy
the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company
elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes,
such Person shall no longer be a Holder of such Notes surrendered for conversion.

 

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

 

Section 14.03. Increased Conversion Rate
Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes. (a) If a Make-Whole Fundamental
Change occurs or becomes effective 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 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).

 

(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 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental
Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental
Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change,
the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an
amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional
Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the
third Business Day following the Conversion Date. The Company shall notify the Holders of Notes 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.

 

    	48

    	 

    

 

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

 

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

 

(e)           
The following table sets forth the number of Additional Shares by which the Conversion Rate shall be increased per $1,000
principal amount of Notes pursuant to this Section 14.03 for each Stock Price and Effective Date set forth below:

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

 

    	49

    	 

    

 

                               (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 $22.50 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion
Rate; and

 

                               (iii)           
if the Stock Price is less than $13.17 per share (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

 

Notwithstanding the foregoing, in no event
shall the Conversion Rate per $1,000 principal amount of Notes exceed 75.9301 shares of Common Stock, subject to adjustment in
the same manner as the Conversion Rate pursuant to Section 14.04.

 

(f)           
Nothing in this Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 14.04 in respect of
a Make-Whole Fundamental Change.

 

Section 14.04. Adjustment of Conversion
Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except
that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case
of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders
of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without
having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by
the principal amount (expressed in thousands) of Notes held by such Holder.

 

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

 

  

 

where,

 

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

 

    	50

    	 

    

 

 

		CR' 	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;

 

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

 

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

 

Any adjustment made under this Section 14.04(a) shall become
effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after
the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution
of the type described in this Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted,
effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

 

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

 

 

 

where,

 

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

 

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

 

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

 

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

 

    	51

    	 

    

 

		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 14.04(b) shall be made
successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of
business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration
of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect
had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate
shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

 

For purposes of this Section 14.04(b) and
for the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe
for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for
the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement
for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account
any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion
thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

 

(c)           
If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the
Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of
the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section
14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected
pursuant to Section 14.04(d), and (iii) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply
(any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire
Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased
based on the following formula:

 

 

  

where,

 

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

 

    	52

    	 

    

 

 

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

 

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

 

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

 

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

 

With respect to an adjustment pursuant
to this Section 14.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital
Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company,
that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”),
the Conversion Rate shall be increased based on the following formula:

 

 

 

where,

 

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

 

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

 

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

 

    	53

    	 

    

 

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

 

The adjustment to the Conversion Rate under the preceding paragraph
shall occur on the last Trading Day of the Valuation Period; provided that in respect of any conversion of Notes during
the Valuation Period, references in the portion of this Section 14.04(c) related to Spin-Offs with respect to 10 Trading Days shall
be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off
and the Conversion Date in determining the Conversion Rate. 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 in the
preceding paragraph to 10 Trading Days will 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 14.04(c) (and
subject in all respect to Section 14.11), rights, options or warrants
distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s
Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until
the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such
shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock,
shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Conversion Rate under
this Section 14.04(c) will be required) until the occurrence of
the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate
adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right, option or
warrant, including any such existing rights, options or warrants distributed prior to the date of this Supplemental Indenture,
are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed
to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which
case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of
the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or
any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted
for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was
made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise
by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights,
options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution,
deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such
holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or
purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise
by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

 

    	54

    	 

    

 

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

 

(A)a dividend or distribution of shares
of Common Stock to which Section 14.04(a) is applicable (the “Clause A Distribution”); or

 

(B)a dividend or distribution of rights,
options or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”),

 

then, in either case, (1) such dividend or
distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution
to which this Section 14.04(c) is applicable (the “Clause
C Distribution”) and any Conversion Rate adjustment required by this Section 14.04(c) with respect to such Clause C
Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow
the Clause C Distribution and any Conversion Rate adjustment required by Section 14.04(a) and Section 14.04(b) with respect thereto
shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution
and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common
Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately
prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding
immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.04(b).

 

(d)           
If any cash dividend or distribution is made to all or substantially all holders of the Common Stock, other than a regular,
monthly (or other regular dividend period the Company has at the time) cash dividend that does not exceed $0.07833 per share (or
proportionally adjusted for any change in the Company’s regular monthly dividend period) (the “Initial Dividend
Threshold”), the Conversion Rate shall be adjusted based on the following formula:

 

 

 

    	55

    	 

    

 

where,

 

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

 

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

 

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

 

		T 	=	the Initial Dividend Threshold; provided that if the dividend or distribution is not a regular cash dividend, the
Initial Dividend Threshold shall be deemed to be zero; and

 

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

 

The Initial Dividend Threshold shall be subject to adjustment
in a manner inversely proportional to adjustments to the Conversion Rate; provided that no adjustment shall be made to the
Initial Dividend Threshold for any adjustment to the Conversion Rate pursuant to this Section 14.04(d).

 

Any increase pursuant to this Section 14.04(d)
shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution.
If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of
Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common
Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to
the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

 

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

 

 

 

    	56

    	 

    

 

where,

 

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

 

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

 

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

 

		OS0 	=	the number of shares of Common Stock outstanding immediately prior to the 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 adjustment to the Conversion Rate under this Section 14.04(e)
shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next
succeeding the date such tender or exchange offer expires; provided that in respect of any conversion of Notes within the
10 Trading Days immediately following, and including, the expiration date of any tender or exchange offer, references in this Section
14.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between
the date that such tender or exchange offer expires and the Conversion Date in determining the Conversion Rate. 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 in the preceding paragraph to
10 Trading Days 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.

 

(f)           
Notwithstanding this Section 14.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment
becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on
or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion
Date as described under Section 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding
the Conversion Rate adjustment provisions in this Section 14.04, the Conversion Rate adjustment relating to such Ex-Dividend Date
shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of
the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving
rise to such adjustment.

 

    	57

    	 

    

 

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

 

(h)           
In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.04, and to the extent
permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities
are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business
Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the
extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities
are then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to
holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock
(or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of
the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Note Register
a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall
state the increased Conversion Rate and the period during which it will be in effect.

 

(i)           
Except as described above in this Article 14, the Conversion Rate shall not be adjusted:

 

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

 

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

 

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

 

    	58

    	 

    

 

                                (iv)          
solely for a change in the par value of the Common Stock or a change in the Company’s jurisdiction of incorporation;

 

                                (v)           
for accrued and unpaid interest, if any; or

 

                                (vi)          
for an event otherwise requiring an adjustment, as described herein if such event is not consummated.

 

(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
such adjustment would require a change of at least 1% in the Conversion Rate. However, the Company shall carry forward any adjustments
that are less than 1% of the Conversion Rate and make such carried forward adjustment, regardless of whether the aggregate adjustment
is less than 1%, on the Conversion Date for any Notes and on each Trading Day of any Observation Period for any converted Notes.

 

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

 

(l)           
For purposes of this Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares
of Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution
on shares of Common Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of
scrip certificates issued in lieu of fractions of shares of Common Stock.

 

Section 14.05. Adjustments of Prices.
Whenever any provision of the 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 Conversion Rate that becomes effective, or any event requiring an adjustment
to the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period when the Last Reported Sale
Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

 

    	59

    	 

    

 

Section 14.06. Shares to Be Fully Paid.
The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient
shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming
that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical
Settlement is applicable).

 

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

 

(a)           
In the case of:

 

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

 

                                (ii)          
any consolidation, merger or combination involving the Company,

 

                                (iii)         
any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries
substantially as an entirety or

 

                                (iv)         
any statutory share exchange,

 

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

 

    	60

    	 

    

 

If the Merger Event causes the Common Stock
to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part
upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed
to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively
make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration
actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding
paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders
of the Common Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs
after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of Notes
shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional
Shares pursuant to Section 14.03), multiplied by the price paid per share of Common Stock in such Merger 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 Merger Event, the Reference Property
includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other
than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall
also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the
Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including, to the extent required
by the Board of Directors and practicable, the provisions providing for the repurchase rights set forth in Article 15.

 

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

 

    	61

    	 

    

 

(c)           
The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 14.07. None
of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into cash, shares of Common Stock
or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 14.01 and Section 14.02 prior to the
effective date of such Merger Event.

 

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

 

(e)           
In connection with any Merger Event, the Initial Dividend Threshold shall be subject to adjustment as described in clause
(i), clause (ii) or clause (iii) below, as the case may be.

 

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

 

                                (ii)          
In the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above and
excluding any dissenters’ appraisal rights) is composed in part of shares of Merger Common Stock, the Initial Dividend Threshold
at and after the effective time of such Merger Event will be equal to (x) the Initial Dividend Threshold immediately prior to
the effective time of such Merger Event, multiplied by (y) the Merger Valuation Percentage for such Merger Event (such
product rounded down to the nearest cent).

 

                                (iii)         
For the avoidance of doubt, in the case of a Merger Event in which the Reference Property (determined, as appropriate, pursuant
to subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other than
shares of common stock, the Initial Dividend Threshold at and after the effective time of such Merger Event will be equal to zero.

 

Section 14.08. Certain Covenants.
(a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable
by the Company and free from all taxes, liens and charges (other than those created by the Holder) 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.

 

    	62

    	 

    

 

(c)           
The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange
or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange
or automated quotation system, any Common Stock issuable upon conversion of the Notes.

 

Section 14.09. Responsibility of Trustee.
The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine
the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase)
of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect
to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and
any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares
of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any
Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality
of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any
event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of
Section 7.01 of the Base Indenture, 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 14.10. Notice to Holders Prior
to Certain Actions. In case of any:

 

(a)           
action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section
14.04 or Section 14.11;

 

    	63

    	 

    

 

(b)           
Merger Event; or

 

(c)           
voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

 

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

 

Section 14.11. Stockholder Rights Plans.
If the Company 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 so that
the Holders would not be entitled to receive any rights in respect of Common Stock, if any, issuable upon conversion of the Notes,
the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders
of the Common Stock Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration,
termination or redemption of such rights.

 

Section 14.12. Limit on Issuance of Shares
of Common Stock Upon Conversion. Notwithstanding anything to the contrary in the Indenture, if an event occurs that would result
in an increase in the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules or listing
standards of any national or regional securities exchange that are applicable to the Company, the Company will, at its option,
either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess of such limitations or
pay cash in lieu of delivering any shares of Common Stock otherwise deliverable upon conversions in excess of such limitations
based on the Daily VWAP for each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering shares
of Common Stock, the Company pays cash pursuant to this Section 14.12.

 

    	64

    	 

    

 

Section 14.13. Ownership Limit. Notwithstanding
any other provision of the Indenture or the Notes, no Holder of Notes shall be entitled to convert such Notes into shares of Common
Stock to the extent that receipt of such shares would cause such Holder (or any other Person) to exceed the ownership limitations
contained in Section 4.07 of the Articles of Amendment and Restatement of the Company dated as of July 5, 2011, filed with the
State Department of Assessments and Taxation of Maryland, as amended on July 2, 2013 and as amended, supplemented or restated from
time to time.

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

 

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

 

                                (i)           
delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”)
in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in
compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in
each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date;
and

 

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

 

    	65

    	 

    

 

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 $1,000 or an integral multiple thereof; and

 

                                (iii)         
that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and the Indenture;

 

provided, however, that if the Notes are Global
Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

 

Notwithstanding anything herein to the
contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 15.02
shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close
of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of
withdrawal to the Paying Agent in accordance with Section 15.03.

 

The Paying Agent shall promptly notify
the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

 

(c)           
On or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Company shall
provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a
notice (the “Fundamental Change Company Notice”) of the occurrence of the effective date of the Fundamental
Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such
notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable
procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information
set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such
information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental
Change Company Notice shall specify:

 

                                (i)           
the events causing the Fundamental Change;

 

                                (ii)          
the date of the Fundamental Change;

 

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

 

                                (iv)         
the Fundamental Change Repurchase Price;

 

    	66

    	 

    

 

                                (v)          
the Fundamental Change Repurchase Date;

 

                                (vi)         
the name and address of the Paying Agent and the Conversion Agent, if applicable;

 

                                (vii)        
if applicable, the Conversion Rate and any adjustments to the Conversion Rate;

 

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

 

(d)           
Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon
a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded,
on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the
Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders
thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from
a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions
for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled,
and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall
be deemed to have been withdrawn.

 

Section 15.03. Withdrawal of Fundamental
Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written
notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 15.03 at any time
prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

 

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

 

    	67

    	 

    

 

                                (ii)          
if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is
being submitted, and

 

                                (iii)         
the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which
portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

 

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

 

Section 15.04. Deposit of Fundamental
Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or
if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.01) on or prior
to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of
the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by
the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior
to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the
later of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions in Section 15.02)
and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company)
by the Holder thereof in the manner required by Section 15.02 by
mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register;
provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds
to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the
Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

 

(b)           
If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed
by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be 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) and (iii)
all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase
Price).

 

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

 

    	68

    	 

    

 

Section 15.05. Covenant to Comply with
Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the Company will, if required:

 

(a)           
comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then
be applicable;

 

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

 

(c)           
otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the
Notes;

 

in each case, so as to permit the rights
and obligations under this Article 15 to be exercised in the time and in the manner specified in this Article 15.

Redemption to Preserve REIT Status

 

Section 16.01. Applicability of Article
III of the Base Indenture. Article III of the Base Indenture shall not apply to the Notes. Instead, the provisions set forth
in this Article 16 shall, with respect to the Notes, supersede
in its entirety Article III of the Base Indenture, and all references in the Base Indenture to Article III thereof and the provisions
therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article
16 and the applicable provisions set forth in this Article 16,
respectively.

 

Section 16.02. Redemption to Preserve
REIT Status. No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Company prior to the Maturity
Date except to the extent, and only to the extent, necessary to preserve the Company’s status as a REIT. If the Company determines
that it is necessary to redeem the Notes prior to the Maturity Date to preserve its status as a REIT, the Company may redeem (a
“Redemption”) for cash all or part of the Notes as necessary to preserve REIT status, at the Redemption Price.

 

Section 16.03. Notice of Redemption;
Selection of Notes. (a) In case the Company exercises its Redemption right to redeem all or, as the case may be, any part of
the Notes pursuant to Section 16.01, it shall fix a date for redemption (each, a “Redemption Date”) and it or,
at its written request received by the Trustee not less than 55 calendar days prior to the Redemption Date (or such shorter period
of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall mail or electronically
deliver or cause to be mailed or electronically delivered a notice of such Redemption (a “Redemption Notice”)
not less than 45 nor more than 60 calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed as a whole
or in part at its last address as the same appears on the Note Register; provided, however, that, if the Company
shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The Redemption Date must be a
Business Day.

 

    	69

    	 

    

 

(b)           
The Redemption Notice, if mailed or electronically delivered in the manner herein provided, shall be conclusively presumed
to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by
mail or electronic delivery or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole
or in part shall not affect the validity of the proceedings for the redemption of any other Note.

 

(c)           
Each Redemption Notice shall specify:

 

                                (i)           
the Redemption Date;

 

                                (ii)          
the Redemption Price;

 

                                (iii)         
that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that interest
thereon, if any, shall cease to accrue on and after the Redemption Date;

 

                                (iv)         
the place or places where such Notes are to be surrendered for payment of the Redemption Price;

 

                                (v)           that Holders
may surrender their Notes for conversion at any time prior to the close of business on the third Scheduled Trading Day immediately
preceding the Redemption Date;

 

                                (vi)         
the procedures a converting Holder must follow to convert its Notes and the Settlement Method and Specified Dollar Amount, if
applicable;

 

                                (vii)        
the Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with
Section 14.03;

 

                                (viii)       
the CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and

 

                                (ix)          
in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and on and after the
Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be
issued.

 

A Redemption Notice shall be irrevocable.

 

(d)           
If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of
a Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on
a pro rata basis or by another method the Trustee considers to be fair and appropriate. If any Note selected for partial
redemption is submitted for conversion in part after such selection, the portion of the Note submitted for conversion shall be
deemed (so far as may be possible) to be the portion selected for redemption.

 

    	70

    	 

    

 

Section 16.04. Payment of Notes Called
for Redemption. (a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 16.03, the Notes
shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable
Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes
shall be paid and redeemed by the Company at the applicable Redemption Price.

 

(b)           
Prior to the open of business on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company
or a Subsidiary of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 7.06 of
the Base Indenture an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the
Redemption Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent,
payment for the Notes to be redeemed shall be made promptly after the later of:

 

                                (i)           
the Redemption Date for such Notes; and

 

                                (ii)          
the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof
in the manner required by this Section 16.04.

 

The Paying Agent shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

 

Section 16.05. Restrictions on Redemption.
The Company may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the
terms of the Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of
an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Notes).

be deemed to include Additional Interest if, in such context, Additional Interest is, was or would be payable pursuant to such
Section 6.04, and any express mention of the payment of Additional Interest in any provision therein shall not be construed as
excluding Additional Interest in those provisions thereof where such express mention is not made.

 

Any Defaulted Amounts shall accrue interest
per annum at the rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law,
from, and including, the relevant payment date to, but excluding, the date on which such Defaulted Amounts shall have been paid
by the Company, at its election, in accordance with Section 2.05(c) of the Supplemental Indenture.

 

The Company shall pay the principal of

the Company for that purpose. The Company has initially designated the Trustee as its Paying Agent and Note Registrar in respect
of the Notes and its agency in the Borough of Manhattan, The City of New York, as a place where Notes may be presented for payment

[FORM OF REVERSE OF NOTE]

 

American Realty Capital Properties, Inc.

3.75% Convertible Senior Note due 2020

 

This Note is one of a duly authorized issue
of Notes of the Company, designated as its 3.75% Convertible Senior Notes due 2020 (the “Notes”), limited to
the aggregate principal amount of $350,000,000 (as increased by an amount equal to the aggregate principal amount of any additional
Notes purchased by the Underwriters pursuant to the exercise of their over-allotment option as set forth in the Underwriting Agreement)
all issued or to be issued under and pursuant to an Indenture dated as of July 29, 2013 (the “Base Indenture”),
as amended and supplemented by the Second Supplemental Indenture dated as of December 10, 2013 (herein called the “Supplemental
Indenture”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, and as it may be further
amended or supplemented from time to time with respect to the Notes, the “Indenture”), by and between the Company
and U.S. Bank National Association (the “Trustee”) to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount,
subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall
have the respective meanings set forth in the Indenture.

 

In case certain Events of Default shall
have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders
of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable,
in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

 

Subject to the terms and conditions of
the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the
Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders
a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United
States that at the time of payment is legal tender for payment of public and private debts.

 

The Indenture contains provisions permitting
the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances,
with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes
as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default
or Event of Default under the Indenture and its consequences.

 

    	A-5

    	 

    

 

No reference herein to the Indenture and
no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional,
to pay or deliver, as the case may be, the principal (including the Fundamental Change Repurchase Price, if applicable) of, accrued
and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the
rate and in the lawful money herein prescribed.

 

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

 

The Notes shall be redeemable only in accordance
with the terms and conditions specified in the Indenture.

 

Upon the occurrence of a Fundamental Change,
the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s
Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase
Date at a price equal to the Fundamental Change Repurchase Price.

 

Subject to the provisions of the Indenture,
the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified
in the Indenture, prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes
or portion thereof that is $1,000 or an integral multiple thereof, into cash, shares of Common Stock or a combination of cash
and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as
provided in the Indenture.
