(c)

per annum at the rate borne by the Notes from, and including, such relevant payment date, and such Defaulted Amounts together with
such interest thereon shall be paid by the Company, at its election in each case, as provided in clauses (i) or (ii) below:

 

(i)                
The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective
Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the 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 in writing 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 sent 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 sent, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes)
are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause
(ii) of this Section 2.03(c).

 

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

 

    16

     

    

 

(iii)             
The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Defaulted
Amounts, or with respect to the nature, extent, or calculation of the amount of Defaulted Amounts owed, or with respect to the
method employed in such calculation of the Defaulted Amounts.

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 this 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 an Officer of the Company, although
at the date of the execution of this Indenture any such Person was not such an Officer.

 

Section

or procedures as it may prescribe, the Company shall provide for the registration of Notes and transfers of Notes. Such register

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. 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

No service charge shall be imposed
by the Company, the Trustee, the Note Registrar or any co-Note Registrar for any registration of transfer or exchange of Notes,

charge required by law or permitted pursuant to this Indenture.

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, surrendered for redemption in accordance with Article 16.

 

All Notes issued upon any registration
of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the
same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or
exchange.

(including the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written
consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be
bound by all such restrictions on transfer. As used in this Section 2.05(b) and Section 2.05(c), the term “transfer”
encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

 

Until the date (the “Resale
Restriction Termination Date”) that is the later of (1) the date that is one year after the Issue Date, or such shorter
period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if
any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor
or substitution thereof, other than Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth
in Section 2.05(c), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred
pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to
be effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar
provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to
the Trustee):

 

THIS SECURITY AND THE COMMON STOCK,
IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY
ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

 

(1)       REPRESENTS
THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A
UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

 

(2)       AGREES
FOR THE BENEFIT OF ROYAL CARIBBEAN CRUISES LTD. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER
THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE
DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO
AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW EXCEPT:

 

    19

     

    

 

(A)      TO
THE COMPANY OR ANY SUBSIDIARY THEREOF;

 

(B)      PURSUANT
TO AN EFFECTIVE REGISTRATION STATEMENT OF THE COMPANY THAT COVERS THE RESALE OF THIS SECURITY OR SUCH COMMON STOCK;

 

(C)      TO
A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT (IF AVAILABLE); OR

 

(D)      PURSUANT
TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.

 

PRIOR TO THE REGISTRATION OF ANY
TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH
LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER
IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY
OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

 

No transfer of any Note prior
to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment
and Transfer has been checked.

 

On any Resale Restriction Termination
Date, the Company shall, at its option, deliver to the Trustee a certificate in the form of Exhibit B hereto executed by an Officer
of the Company, and upon the Trustee’s receipt of such certificate the restrictive legend required by this Section 2.05(b)
shall be deemed removed from any Global Notes representing such Notes without further action on the part of Holders. If the Company
delivers such a certificate to Trustee, the Company shall: (i) notify Holders of the Notes that the restrictive legend required
by this Section 2.05(b) has been removed or deemed removed; and (ii) instruct the Depositary to change the CUSIP number for the
Notes to the unrestricted CUSIP number for the Notes. It is understood that the Depositary of any Global Note may require a mandatory
exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such
Depositary. For the avoidance of doubt, for Notes that are not in certificated form, the Notes shall continue to bear Additional
Interest pursuant to this paragraph until such time as they are identified by an unrestricted CUSIP number in the facilities of
the Depositary or any successor depositary for the Notes, as a result of completion of the Depositary’s mandatory exchange
process or otherwise.

  

    20

     

    

 

 

Any Note (or security issued in
exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their terms,
(ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under
the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the
exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender
of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new
Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section
2.05(b) and shall not be assigned a restricted CUSIP number.

 

The Company shall be entitled
to instruct the Custodian in writing to so surrender any Global Note as to which such restrictions on transfer shall have expired
in accordance with their terms for exchange, and, upon such instruction, the Custodian shall so surrender such Global Note for
exchange; and any new Global Note so exchanged therefor shall not bear the restrictive legend specified in this Section 2.05(b)
and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Resale
Restriction Termination Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock
issued upon conversion of the Notes has been declared effective under the Securities Act.

 

Notwithstanding any other provisions
of this Indenture (other than the provisions set forth in this Section 2.05(b)), 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 Applicable Procedures and in compliance with this Section 2.05(b).

 

The Depositary shall be a clearing
agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as the “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.

 

    21

     

    

 

If:

 

(a)              
the Depositary (i) 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 or (ii) ceases to be a clearing agency registered
under the Exchange Act and a successor depositary is not appointed within 90 days; or

 

(b)              
there has occurred and is continuing an Event of Default and a beneficial owner of any Note requests through the Depositary
that its beneficial interest therein be issued in a Certificated Note,

 

the Company shall execute, and the
Trustee, upon receipt of an Officer’s Certificate, an Opinion of Counsel and a Company Order for the authentication and delivery
of Notes, shall authenticate and deliver Certificated 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.

 

Certificated Notes issued in exchange
for all or a part of the Global Note pursuant to this Section 2.05(b) 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 Certificated Notes to the Persons in whose names
such Certificated 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 Applicable 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 Certificated Notes, converted, canceled,
repurchased or transferred to a transferee who receives Certificated Notes therefor or any Certificated Note is exchanged or transferred
for part of such Global Note, the principal amount of such Global Note shall, in accordance with the Applicable Procedures and
instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and
an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect
such reduction or increase.

 

Neither the Company, the Trustee
nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records
relating to such beneficial ownership interests. Neither the Company nor the Trustee shall have any responsibility or liability
for any act or omission of the Depositary.

 

    22

     

    

 

(c)              
Until the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of
a Note shall bear a legend in substantially the following form (unless the Note or such Common Stock has been transferred pursuant
to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective
at the time of such transfer, or pursuant to the exemption from registration provided by Rule 144 or any similar provision then
in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee and
any transfer agent for the Common Stock):

 

THIS SECURITY HAS NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE
TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE
ACQUIRER:

 

(1)       REPRESENTS
THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A
UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

 

(2)       AGREES
FOR THE BENEFIT OF ROYAL CARIBBEAN CRUISES LTD. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER
THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE
DATE OF THE NOTE UPON THE CONVERSION OF WHICH SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER
THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW EXCEPT:

 

(A)       TO
THE COMPANY OR ANY SUBSIDIARY THEREOF;

 

(B)       PURSUANT
TO AN EFFECTIVE REGISTRATION STATEMENT OF THE COMPANY THAT COVERS THE RESALE OF THIS SECURITY OR SUCH COMMON STOCK;

 

(C)       TO
A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT (IF AVAILABLE); OR

 

    23

     

    

 

(D)       PURSUANT
TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.

 

PRIOR TO THE REGISTRATION OF ANY
TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT FOR THE COMMON STOCK RESERVE THE RIGHT TO REQUIRE
THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT
THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION
IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

 

(d)              
Any such Common Stock (i) as to which such restrictions on transfer shall have expired in accordance with their terms, (ii)
that has been transferred pursuant to a registration statement that has become or been declared effective under the Securities
Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of the certificates
representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock,
be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear
the restrictive legend required by Section 2.05(c).

 

(e)              
Any Note that is repurchased or owned by an Affiliate of the Company (or any Person who was an Affiliate of the Company
at any time during the three months immediately preceding) may not be resold by such Affiliate 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 no longer being a “restricted security” (as defined under Rule 144 under the Securities Act). The Trustee
shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between
or among members of, or participants in, the Depositary or beneficial owners of interests in any Global Note) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly
required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof.

 

(f)               
Neither the Trustee nor any agent of the Trustee shall have any responsibility for any actions taken or not taken by the
Depositary.

 

    24

     

    

 

Section
2.06.      Mutilated, Destroyed, Lost or Stolen Notes.
In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its
written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing
a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and
in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to
the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be reasonably 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 reasonably require. Upon the issuance of any substitute Note, the
Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental
charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or
is about to mature, is subject to Tax Redemption 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 reasonably
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, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying
Agent or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

 

Every substitute Note issued pursuant
to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall
be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately
with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the
express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase
of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments
or other securities without their surrender.

 

    25

     

    

 

Section
2.07.      Temporary Notes.
Pending the preparation of Certificated 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 Certificated 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 Certificated Notes. Without unreasonable delay,
the Company shall execute and deliver to the Trustee or such authenticating agent Certificated Notes (other than any Global Note)
and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office
or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and
deliver in exchange for such temporary Notes an equal aggregate principal amount of Certificated Notes. Such exchange shall be
made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects
be entitled to the same benefits and subject to the same limitations under this Indenture as Certificated Notes authenticated
and delivered hereunder.

 

Section
2.08.      Cancellation of Notes Paid, Converted, Etc.
The Company shall cause all Notes surrendered for the purpose of payment, redemption, repurchase (but excluding Notes repurchased
pursuant to cash-settled swaps or other derivatives that are not physically settled), registration of transfer or exchange or
conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or
Affiliates), to be delivered to the Trustee for cancellation, and such Notes shall no longer be considered outstanding for purposes
of this Indenture upon their payment, redemption, repurchase, registration of transfer or exchange or conversion. All Notes delivered
to the Trustee shall be canceled promptly by it in accordance with its customary procedures. No Notes shall be authenticated in
exchange for any Notes cancelled, except as expressly permitted by any of the provisions of this Indenture. The Trustee shall
dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver evidence of such
disposition to the Company, at the Company’s written request in a Company Order. If the Company or any of the Company’s
Subsidiaries shall acquire any of the Notes, such acquisition shall not operate as a purchase or satisfaction of the indebtedness
represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

 

Section
2.09.      CUSIP Numbers.
The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall
use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such
notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such
notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly
notify the Trustee in writing of any change in the “CUSIP” numbers.

 

Section
2.10.      Additional Notes; Purchases.
(a) The Company may, from time to time, without the consent of, or notice to, the Holders, reopen this Indenture and issue
additional Notes under this Indenture with the same terms as the Notes issued on the Issue Date (other than differences in the
issue date, the issue price and interest accrued prior to the issue date of such additional Notes and, if applicable, the initial
Interest Payment Date and restrictions on transfer in respect of such additional Notes) in an unlimited aggregate principal amount;
provided that if any such additional Notes are not fungible with the Notes issued on the Issue Date for U.S. federal income tax
or securities law purposes, such additional Notes shall have one or more separate CUSIP numbers. Such Notes issued on the Issue
Date and the additional Notes shall rank equally and ratably and shall be treated as a single series for all purposes under this
Indenture. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s
Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition
to those required by Section 17.06, as the Trustee shall reasonably request.

 

    26

     

    

 

(b)              
The Company may, to the extent permitted by law and without the consent of Holders, 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 private or public tenders or exchange offers or through counterparties to private agreements, including
by cash-settled swaps or other derivatives. The Company shall cause any Notes so purchased (but excluding Notes repurchased pursuant
to cash-settled swaps or other derivatives that are not physically settled) to be surrendered to the Trustee for cancellation in
accordance with Section 2.08, and they will no longer be considered outstanding under this Indenture upon their repurchase.

 

Article

Satisfaction And Discharge

 

Section
3.01.      Satisfaction and Discharge.
This Indenture and the Notes shall upon request of the Company contained in an Officer’s Certificate cease to be of further
effect (except as set forth in the last paragraph of this Section 3.01), and the Trustee, at the expense and direction of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when:

 

(i)                
either:

 

(A)       all
Notes theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been deposited in trust with
the Trustee or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust,
as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or

 

(B)       the
Company has deposited with the Trustee or delivered to Holders, as applicable, after all of the outstanding Notes have (I) become
due and payable, whether at the Maturity Date, upon a Tax Redemption or at any Fundamental Change Repurchase Date, and/or (II)
have been converted (and the related Settlement Amounts have been determined), cash or, solely to satisfy the Company’s Conversion
Obligations, cash and/or shares of Common Stock (or if applicable, reference property), as applicable, sufficient to pay all of
the outstanding Notes and/or satisfy all conversions, as the case may be, and pay all other sums due and payable under this Indenture
by the Company; and

 

    27

     

    

 

(ii)             
the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all
conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

 

Notwithstanding the satisfaction and discharge of
this Indenture, the obligations of the Company to the Trustee under Section 7.06 and, if cash or shares of Common Stock shall have
been deposited with the Trustee pursuant to Section 3.01(i)(B), Section 4.04 shall survive such satisfaction and discharge.

 

Article

Particular Covenants of the Company

 

Section
4.01.      Payment of Principal, Settlement Amounts and Interest.
The Company shall pay or cause to be paid the principal (including the Redemption Price and the Fundamental Change Repurchase
Price, if applicable) of, the Settlement Amounts owed on conversion of, and interest on the Notes on the dates and in the manner
provided in the Notes. Principal, Settlement Amounts and interest shall be considered paid on the date due if the Paying Agent,
if other than the Company, holds as of 10:00 a.m., New York City time, on the due date money deposited by the Company in immediately
available funds and designated for and sufficient to pay all principal, Settlement Amounts and interest then due. Unless such
Paying Agent is the Trustee, the Company will promptly notify the Trustee in writing of any failure to take such action.

 

The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal (including the Redemption Price
and the Fundamental Change Repurchase Price, if applicable) and overdue Settlement Amounts owed on conversion to the extent they
include cash, at the rate equal to the interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition

period), at the same rate to the extent lawful.

 

Section
4.02.      Maintenance of Office or Agency.
The Company shall at all times maintain an office or agency in the continental United States (which may be an office of the Trustee
or an Affiliate of the Trustee) where Notes may be presented or surrendered for registration of transfer or exchange or for payment,
redemption or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where
notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company shall give prompt
written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

 

    28

     

    

 

The Company may also from time
to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations. Further, if at any time there shall be no such office or agency in the continental
United States where the Notes may be presented or surrendered for payment, the Company shall forthwith designate and maintain such
an office or agency in the continental United States, in order that the Notes shall at all times be payable in the continental
United States. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change
in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent”
include any such additional or other offices or agencies, as applicable.

 

The Company hereby appoints the
Trustee as Paying Agent, Note Registrar, Custodian and Conversion Agent and designates the Corporate Trust Office of the Trustee
as one such office or agency of the Company.

 

The Company reserves the right
to vary or terminate the appointment of any Note Registrar, Paying Agent or Conversion Agent, and Bid Solicitation Agent; act as
the Paying Agent or Bid Solicitation Agent; appoint additional Paying Agents or Conversion Agents; or approve any change in the
office through which any Note Registrar or Paying Agent or Conversion Agent acts.

 

Section
4.03.      Appointments to Fill Vacancies in Trustee’s Office.
The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, shall appoint, in the manner provided in
Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

 

Section
4.04.      Provisions as to Paying Agent.
(a) If the Company shall appoint a Paying Agent other than the Trustee, the Company shall cause such Paying Agent to execute
and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section
4.04:

 

(i)                
that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and
the Fundamental Change Repurchase Price, if applicable) of, the Settlement Amounts owed on conversion to the extent they include
cash, 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 written 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, the Settlement Amounts owed on conversion
to the extent they include cash, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and

 

    29

that at any time during the continuance of an Event of Default, upon request of the Trustee, it shall forthwith pay to the
Trustee all sums so held in trust.

 

(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, the Settlement Amounts owed on conversion to the extent they
include cash, 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), cash portion of the Settlement Amounts 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, the Settlement Amounts owed on
conversion to the extent they include cash, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

 

(c)              
Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining
a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums
or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to
be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to
the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or
amounts.

 

(d)              
Subject to any applicable escheat laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company,
in trust for the payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable)
of, the Settlement Amounts owed on conversion to the extent they include cash, and accrued and unpaid interest on, any Note and
remaining unclaimed for two years after such principal (including the Redemption Price and the Fundamental Change Repurchase Price,
if applicable), the Settlement Amounts owed on conversion to the extent they include cash, or interest has become due and payable
shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and
all liability of the Company as trustee thereof, shall thereupon cease.

Section
4.06.      Rule 144A Information Requirement; Reporting; and Additional Interest.
(a) For as long as any Notes are outstanding hereunder, at any time the Company is not subject to Sections 13 and 15(d)
of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issued upon conversion of the
Notes shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities
Act, promptly provide to the Trustee and will, upon written request, provide to any Holder, beneficial owner or prospective purchaser
of such Notes or any shares of Common Stock issued upon conversion of the Notes, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or such Common Stock, as the case may be, pursuant
to Rule 144A under the Securities Act. The Company shall take such further action as any Holder or beneficial owner of such Notes
or such Common Stock, as the case may be, may reasonably request to the extent from time to time required to enable such Holder
or beneficial owner to sell such Notes or such Common Stock, as the case may be, in accordance with Rule 144A under the Securities
Act, as such rule may be amended from time to time.

 

    30

     

    

 

(b)              
The Company shall furnish to the Trustee within 15 days after the same are required to be filed with the Commission (after
giving effect to any grace period provided by Rule 12b-25 under the Exchange Act or any successor rule under the Exchange Act or
any special order of 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 (excluding any such information, documents or reports, or portions thereof,
subject to confidential treatment and any correspondence with the Commission). Any such document or report that the Company files
with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be furnished to the Trustee
for purposes of this Section 4.06(b) as of the time such documents are filed via the EDGAR system (or such successor).

 

(c)              
Delivery of the reports, information and documents described in Section 4.06(a) and (b) to the Trustee is for informational
purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with any of the Company’s
covenants under this Indenture or the Notes (as to which the Trustee is entitled to conclusively rely on an Officer’s Certificate).
The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with
the covenants or with respect to any reports or other documents filed with the Commission or the Commission’s EDGAR system
(or any successor thereto) or posted on any website or to participate in any conference calls.

 

(d)              
Subject to Section 6.03(b), if, at any time during the six-month period beginning on, and including, the date that is six
months after the Issue Date, the Company fails to timely file any document or report that it is required to file with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (other than Current Reports on Form 8-K), after giving effect
to all applicable grace period thereunder, or the Notes are not otherwise freely tradable by Holders other than the Company’s
Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding (as a result
of restrictions pursuant to U.S. federal securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional
Interest on the Notes from, and including, the first date after the conclusion of the six-month period described above on which
such failure to file occurs or the first date the Notes are not otherwise freely tradable as described above by Holders other than
the Company’s Affiliates or Holders that were Affiliates of the Company at any time during the three months immediately preceding
without restriction pursuant to U.S. federal securities laws or the terms of this Indenture or the Notes, whichever is earlier,
until the earlier of (i) the one-year anniversary of the Issue Date and (ii) the date on which such failure to file has been cured
(if applicable) and the Notes are otherwise freely tradable by Holders other than the Company’s Affiliates or Holders that
were Affiliates of the Company at any time during the three months immediately preceding without restriction pursuant to U.S. federal
securities laws or the terms of this Indenture or the Notes. Such Additional Interest shall accrue on the Notes at a rate equal
to 0.50% per annum of the principal amount of the Notes outstanding for each day during such period described in the preceding
sentence.

 

    31

     

    

 

(e)              
Subject to Section 4.06(f) and Section 6.03(b), if, and for so long as, the restrictive legend on the Notes specified in
Section 2.05(b) has not been removed (or deemed removed), the Notes are assigned a restricted CUSIP number or the Notes are not
otherwise freely tradable as described in Section 4.06(d) by Holders other than the Company’s Affiliates or Holders that
were Affiliates of the Company at any time during the three months immediately preceding without restrictions pursuant to U.S.
federal securities law or the terms of this Indenture or the Notes as of the 385th day after the Issue Date, the Company shall
pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the
restrictive legend on the Notes specified in Section 2.05(b) has been removed (or deemed removed), the Notes are assigned an unrestricted
CUSIP number and the Notes are freely tradable as described in Section 4.06(d) by Holders other than the Company’s Affiliates
or Holders that were Affiliates of the Company at any time during the three months immediately preceding without restrictions pursuant
to U.S. federal securities laws or the terms of this Indenture or the Notes. The restrictive legend on the Notes shall be deemed
removed pursuant to the terms of this Indenture upon notice by the Company to the Trustee and delivery of the documents required
pursuant to this Indenture, and, at such time, the Notes will be automatically assigned an unrestricted CUSIP. However, for the
avoidance of doubt, for Notes that are not in certificated form, the Notes shall continue to bear Additional Interest pursuant
to this Section 4.06(e) until such time as such Notes are identified by an unrestricted CUSIP in the facilities of the Depositary
as a result of completion of the Depositary’s mandatory exchange process or otherwise.

 

(f)               
Additional Interest, which shall constitute the sole remedy relating to the failure to comply with the Company’s obligations
under this Section 4.06, shall be payable in arrears on each Interest Payment Date following accrual in the same manner as regular
interest on the Notes and shall be in addition to any Additional Interest that may accrue, at the Company’s election, pursuant
to Section 6.03. In no event, however, shall Additional Interest accrue on any day (taking into consideration any Additional Interest
payable as described in Section 4.06(d), Section 4.06(e) or Section 6.03(a)) at a rate in excess of 0.50% per annum, regardless
of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

 

(g)              
If Additional Interest is payable by the Company pursuant to Section 4.06(d), Section 4.06(e) or Section 6.03(a), the Company
shall deliver to the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Additional Interest that
is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee
receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest
is payable.

 

    32

     

    

 

(h)              
To the extent that any reports or other information required by this Section 4.06 is not furnished within the time periods
specified in this Section 4.06 and such reports or other information is subsequently furnished, the Company will be deemed to have
satisfied its obligations with respect thereto and any Default or Event of Default with respect thereto shall be deemed to have
been cured.

 

Section
4.07.      Additional Amounts.

 

(a)              
All payments made by or on behalf of the Company (including any successor entity), under or with respect to the Notes will
be made free and clear of and without withholding or deduction for, or on account of, any present or future tax, duty, levy, impost,
assessment or other governmental charge (including penalties, interest and additions to tax related thereto, and, for the avoidance
of doubt, including any withholding or deduction for or on account of the foregoing) (“Taxes”) unless the withholding
or deduction of such Taxes is then required by law. If the Company or any other applicable withholding agent is required by law
to withhold or deduct any amount for, or on account of, any Taxes imposed or levied by or on behalf of (1) any jurisdiction (other
than the United States) in which the Company is or was incorporated, engaged in business, organized or resident for tax purposes
or any political subdivision thereof or therein or (2) any jurisdiction from or through which any payment is made by or on behalf
of the Company (including, without limitation, the jurisdiction of any Paying Agent) or any political subdivision thereof or therein
(each of (1) and (2), a “Tax Jurisdiction”) in respect of any payments under or with respect to the Notes, including,
without limitation, payments of principal, Redemption Price, purchase price, payments upon conversion, interest or premium, the
Company will pay such additional amounts (the “Additional Amounts”) as may be necessary in order that the net
amounts received and retained in respect of such payments by each beneficial owner of Notes after such withholding or deduction
will equal the respective amounts that would have been received and retained in respect of such payments in the absence of such
withholding or deduction; provided, however, that no Additional Amounts will be payable with respect to:

 

(i)                
any Taxes, to the extent such Taxes would not have been imposed but for the Holder or the beneficial owner of the Notes
(or a fiduciary, settlor, beneficiary, partner of, member or shareholder of, or possessor of a power over, the relevant Holder,
if the relevant Holder is an estate, trust, nominee, partnership, limited liability company or corporation) being or having been
a citizen or resident or national of, or incorporated, engaged in a trade or business in, being or having been physically present
in or having a permanent establishment in, the relevant Tax Jurisdiction or having or having had any other present or former connection
with the relevant Tax Jurisdiction, other than any connection arising solely from the acquisition, ownership or disposition of
Notes, the exercise or enforcement of rights under such Note or this Indenture, or the receipt of payments in respect of such Note;

 

    33

     

    

 

(ii)             
any Taxes, to the extent such Taxes were imposed as a result of the presentation of a Note for payment (where presentation
is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent
that the Holder would have been entitled to Additional Amounts had the Note been presented on the last day of such 30 day period);

 

(iii)           
any estate, inheritance, gift, sale, transfer, personal property or similar Taxes;

 

(iv)            
any Taxes payable other than by deduction or withholding from payments under, or with respect to, the Notes;

 

(v)              
any Taxes to the extent such Taxes would not have been imposed or withheld but for the failure of the Holder or beneficial
owner of the Notes, following the Company’s reasonable written request addressed to the Holder at least 60 days before any
such withholding or deduction would be imposed, to comply with any certification, identification, information or other reporting
requirements, whether required by statute, treaty, regulation or administrative practice of a Tax Jurisdiction, as a precondition
to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Tax Jurisdiction (including, without
limitation, a certification that the Holder or beneficial owner is not resident in the Tax Jurisdiction), but in each case, only
to the extent the Holder or beneficial owner is legally eligible to provide such certification or documentation;

 

(vi)            
any Taxes imposed in connection with a Note presented for payment (where presentation is permitted or required for payment)
by or on behalf of a Holder or beneficial owner of the Notes to the extent such Taxes could have been avoided by presenting the
Note to, or otherwise accepting payment from, another paying agent;

 

(vii)         
any Taxes imposed on or with respect to any payment by the Company to the Holder of the Notes if such holder is a fiduciary
or partnership or any person other than the sole beneficial owner of such payment to the extent that such Taxes would not have
been imposed on such payments had such Holder been the sole beneficial owner of such Note;

 

(viii)       
any Taxes that are imposed pursuant to current Section 1471 through 1474 of the Code or any amended or successor version
that is substantively comparable and not materially more onerous to comply with, any regulations promulgated thereunder, any official
interpretations thereof, any intergovernmental agreement between a non-U.S. jurisdiction and the United States (or any related
law or administrative practices or procedures) implementing the foregoing or any agreements entered into pursuant to current Section
1471(b)(1) of the Code (or any amended or successor version described above); or

 

    34

     

    

 

(ix)            
any combination of clauses (i) through (viii) above.

 

(b)              
In addition to the foregoing, the Company will also pay and indemnify the Holder for any present or future stamp, issue,
registration, value added, court or documentary Taxes, or any other excise or property taxes, charges or similar levies (including
penalties, interest and additions to tax related thereto) which are levied by any jurisdiction on
the execution, delivery, issuance, or registration of the Notes, this Indenture, or any other document referred to therein, or
the receipt of any payments with respect thereto, or enforcement of the Notes (limited, solely in the case of Taxes attributable
to the receipt of any payments, to any such Taxes imposed in a Tax Jurisdiction that are not excluded under clauses (i) through
(iii) or (v) through (ix) above or any combination thereof).

 

(c)              
If the Company becomes aware that it will be obligated to pay Additional Amounts with respect to any payment under or with
respect to the Notes, the Company will deliver to the Trustee on a date that is at least 30 days prior to the date of that payment
(unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment date, in which case the Company
shall notify the Trustee promptly thereafter) an Officer’s Certificate stating the fact that Additional Amounts will be payable
and the amount estimated to be so payable. The Officer’s Certificates must also set forth any other information reasonably
necessary to enable the Paying Agent to pay Additional Amounts to holders on the relevant payment date. The Company will provide
the Trustee with documentation reasonably satisfactory to the trustee evidencing the payment of such Additional Amounts. The Trustee
shall be entitled to rely absolutely on an Officer’s Certificate as conclusive proof that such payments are necessary.

 

(d)              
The Company will make all withholdings and deductions (within the time period) required by law and will remit the full amount
deducted or withheld to the relevant Tax authority in accordance with applicable law. The Company will use its reasonable efforts
to obtain Tax receipts from each Tax authority evidencing the payment of any Taxes so deducted or withheld. The Company will furnish
to the Trustee (or to a Holder of the Notes upon request), within 60 days after the date the payment of any Taxes so deducted or
withheld is made, certified copies of Tax receipts evidencing payment by the Company, or if, notwithstanding the Company’s
efforts to obtain receipts, receipts are not obtained, other evidence of payments by the Company.

 

(e)              
Whenever in this Indenture or the Notes there is mentioned, in any context, the payment of amounts based upon the principal
amount of the notes or of principal, interest or of any other amount payable under, or with respect to the Notes, such mention
shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts
are, were or would be payable in respect thereof.

 

    35

     

    

 

(f)               
This Section 4.07 will survive any termination, defeasance or discharge of this Indenture, any transfer by a holder or beneficial
owner of its Notes, and will apply, mutatis mutandis, to any jurisdiction in which any successor person to the Company is
incorporated, engaged in business, organized or resident for tax purposes, or any jurisdiction from or through which payment is
made under or with respect to the Notes by or on behalf of such person and, in each case, any political subdivision thereof or
therein.

 

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

 

Section
4.09.      Compliance Certificate; Statements as to Defaults.

 

(a)              
The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year (beginning with the year ended
December 31, 2020), an Officer’s Certificate stating whether the signers thereof have knowledge of any Default that occurred
during the previous year and is then continuing, if so, specifying each such failure and the nature thereof.

 

(b)              
The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee an Officer’s Certificate within
30 days after an Officer of the Company becomes aware of the occurrence of any event that would constitute a Default or Event of
Default, specifying each such event, the status thereof and what action the Company is taking or proposes to take with respect
thereto.

 

    36

     

    

 

Section
4.10.      Further Instruments and Acts.
Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

 

Section
4.11.      No Rights as Shareholders.
Holders of Notes, as such, will not have any rights as shareholders of the Company (including, without limitation, voting rights
and rights to receive any dividends or other distributions on Common Stock).

In case one or more Events of Default shall have occurred and be continuing (other than an Event of Default specified in Section
6.01(h) with respect to the Company, any of the Company’s Significant Subsidiaries or any group of the Company’s Subsidiaries
that, taken together, would constitute a Significant Subsidiary), either the Trustee by notice in writing to the Company, or the
Holders of at least 30% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company and the
Trustee, may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the Notes to be due and payable
immediately, and upon any such declaration the same shall become and shall be immediately due and payable. If an Event of Default
specified in Section 6.01(h) with respect to the Company, any of the Company’s Significant Subsidiaries or any group of
the Company’s Subsidiaries that, taken together, would constitute a Significant Subsidiary, 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.

 

    38

     

    

 

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 and on such principal at the rate borne by the Notes at such time) and amounts
due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of
competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal
of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured
or waived pursuant to Section 6.09 and all amounts owing to the Trustee have been paid, then and in every such case (except as
provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding,
by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and
rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding
anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event
of Default resulting from (i) the nonpayment of the principal (including the Redemption Price or the Fundamental Change Repurchase
Price, if applicable) of, or accrued and unpaid interest on, any Notes or (ii) a failure to pay or deliver, as the case may be,
the consideration due upon conversion of the Notes.

 

Section
6.03.      Additional Interest.

 

(a)              
Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy
for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b)
shall, after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the
Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the period beginning
on, and including, the date on which such Event of Default first occurred and ending on the earlier of (x) the date on which such
Event of Default is cured or validly waived in accordance with this Indenture and (y) the 180th day immediately following, and
including, the date on which such Event of Default first occurred; and (ii) if such Event of Default has not been cured or validly
waived prior to the 181st day immediately following, and including, the date on which such Event of Default first occurred, 0.50%
per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the 181st
day immediately following, and including, the date on which such Event of Default first occurred and ending on the earlier of (x)
the date on which the Event of Default is cured or validly waived and (y) the 360th day immediately following, and including, the
date on which such Event of Default first occurred (in addition to any Additional Interest that may accrue as a result of a registration
default pursuant to Sections 4.06(d) and 4.06(e)). For the avoidance of doubt, the first 180-day period described in this Section
6.03 shall not commence until expiration of the 60 day period referenced in Section 6.01(f).

 

    39

     

    

 

(b)              
Any Additional Interest payable pursuant to Section 6.03(a) shall be in addition to any Additional Interest that may accrue
pursuant to Sections 4.06(d) and 4.06(e). Notwithstanding anything in this Indenture to the contrary, in no event, however, shall
Additional Interest accrue on any day (taking into consideration any Additional Interest payable pursuant to Section 6.03(a), together
with Additional Interest payable pursuant to Sections 4.06(d) and 4.06(e)) at a rate in excess of 0.50% per annum, regardless of
the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

 

(c)              
If the Company elects to pay Additional Interest pursuant to Section 6.03(a), such Additional Interest shall be payable
in the same manner and on the same dates as the stated interest payable on the Notes and will accrue on all Notes then outstanding
from, and including, the date on which the Event of Default relating to the Company’s failure to comply with its obligations
as set forth in Section 4.06(b) first occurs to, but not including, the 361st day thereafter (or such earlier date on which such
Event of Default is cured or waived by the Holders of a majority in principal amount of the Notes then outstanding). On the 361st
day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations
as set forth in Section 4.06(b) is not cured or waived prior to such 361st day), such Additional Interest will cease to accrue
and the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional
Interest following an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section
4.06(b) in accordance with this Section 6.03, or the Company elects to make such payment but does not pay the Additional Interest
when due, the Notes shall immediately be subject to acceleration as provided in Section 6.02. For the avoidance of doubt, the provisions
of this Section 6.03 shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. In no
event shall Additional Interest payable pursuant to the foregoing election accrue at a rate per year in excess of the applicable
rate specified in Section 6.03(b), regardless of the number of events or circumstances giving rise to requirements to pay such
Additional Interest pursuant to this Section 6.03.

 

(d)              
In order to elect to pay Additional Interest as the sole remedy during the first 360 days after the occurrence of an Event
of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b), the Company
must notify, in writing, all Holders of the Notes, the Trustee and the Paying Agent (if other than the Trustee) of such election
on or before the close of business on the date on which such Event of Default first occurs. Upon the Company’s failure to
timely give such notice or pay Additional Interest, the Notes shall be immediately subject to acceleration as provided in in Section
6.02. The Company may elect to pay Additional Interest with respect to multiple Events of Default in a single written notification.

 

    40

     

    

 

Section
6.04.      Payments of Notes on Default; Suit Therefor.
If an Event of Default described in Section 6.01 (a), (b) or (c) shall have occurred and the Notes have become due and payable
pursuant to Section 6.02, the Company shall, upon demand of the Trustee (acting at the written direction of the Holders of a majority
in principal amount of the then outstanding Notes), 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 (including the Redemption Price or the Fundamental Change Repurchase Price,
if applicable), satisfaction of the Conversion Obligation with respect to all Notes that have been converted, and interest, if
any, with (to the extent that payment of such interest shall be legally enforceable) interest on any such overdue amounts, at
the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts
due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee,
in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due
and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other
obligor upon the Notes and collect the monies 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 under Bankruptcy Law, 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, the property of the Company, or in the event of any other judicial proceedings
relative to the Company, or to the creditors or property of the Company, the Trustee, irrespective of whether the Trustee shall
have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest,
if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents
and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the
Holders allowed in such judicial proceedings relative to the Company, its creditors, or its property, and to collect and receive
any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts
due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian
or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses,
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee
any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including
any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that
such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be
denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or otherwise.

 

    41

     

    

 

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

 

All rights of action and of asserting
claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes,
or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for
the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for
the ratable benefit of the Holders of the Notes.

 

In any proceedings brought by
the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall
be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders
of the Notes parties to any such proceedings.

 

In case the Trustee shall have
proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any
waiver, rescission or annulment pursuant to Section 6.09 or for any other reason or shall have been determined adversely to the
Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding,
be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the
Holders, and the Trustee shall continue as though no such proceeding had been instituted.

 

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

 

FIRST:          to the payment of all
amounts due the Trustee, including its agents and counsel, under this Indenture;

 

SECOND:     to the payment of the
amounts then due and unpaid for principal of, the Redemption Price (if applicable) and then Fundamental Change Repurchase Price
(if applicable) of, and/or satisfaction of the Conversion Obligation with respect to all Notes that have been converted, and interest
on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority
of any kind, according to the amounts due and payable on such Notes; and

 

    42

     

    

 

THIRD:         to the Company.

 

Section
6.06.      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 and/or delivery of the consideration due upon conversion,
no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit,
action or proceeding in equity or at law upon or under or with respect to this Indenture , or for the appointment of a receiver,
trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

 

(a)              
such Holder has previously given the Trustee written notice that an Event of Default is continuing;

 

(b)             
the Holders of at least 30% in aggregate principal amount of the then outstanding Notes have requested the Trustee in writing
to pursue the remedy;

 

(c)              
such Holders have offered the Trustee security or indemnity satisfactory to the Trustee against any loss, liability, claim
or expense;

 

(d)              
the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of such security or
indemnity; and

 

(e)              
the Holders of a majority in principal amount of the then outstanding Notes have not given the Trustee a direction that,
in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

 

A Holder may not use this Indenture
to prejudice the rights of another Holder or to obtain a preference or priority over another Holder, it being understood that the
Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are unduly prejudicial
to other Holders.

 

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

 

Section
6.07.      Proceedings by Trustee.
In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit
in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant
or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law.

 

    43

     

    

 

Section
6.08.      Remedies Cumulative and Continuing.
Except as provided in the last paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to
the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers
and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance
or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder
of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or
power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject
to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may
be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

 

Section
6.09.      Direction of Proceedings and Waiver of Defaults by Majority of Holders.

 

(a)              
The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding 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 (i) such direction shall not
be in conflict with any rule of law or with this Indenture, and (ii) the Trustee may take any other action deemed proper by the
Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that conflicts with any rule
of law or with this Indenture, it determines is unduly prejudicial to the rights of any other Holder (it being understood that
the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders)
or that would involve the Trustee in personal liability.

 

(b)             
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 hereunder and rescind any acceleration with respect to the Notes
and its consequences hereunder except:

 

(i)               
a default in the payment of the principal (including any Redemption Price and any Fundamental Change Repurchase Price, if
applicable) of, or accrued and unpaid interest, if any, on the Notes;

 

(ii)              
a failure by the Company to deliver the consideration due upon conversion of the Notes; or

 

(iii)             
with respect to any other provision that requires the consent of each affected Holder pursuant to Section 10.02 to amend;

 

provided
that, in the case of the rescission of any acceleration with respect to the Notes, (1) the rescission would not conflict
with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default (other than the nonpayment
of the principal of and interest on the Notes that have become due solely by such declaration of acceleration) have been cured
or waived and all amounts owing to the Trustee have been paid.

 

    44

     

    

 

Whenever any Default or Event of Default hereunder
shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes
and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

 

Section
6.10.      Notice of Defaults.
If a Default occurs and is continuing and a Responsible Officer of the Trustee has received written notice of the Default, the
Trustee shall deliver to all Holders as the names and addresses of such Holders appear upon the Note Register notice of such Default
within 90 days after it occurs. Except in the case of a Default in the payment of principal of (including the Redemption Price
and the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, if any, on any Note or a Default in
the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if
and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

 

Section
6.11.      Undertaking to Pay Costs.
All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that
any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of
an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted
by law) shall not apply to any suit institute d 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, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (including, but not limited to, the Redemption Price and the Fundamental
Change Repurchase Price with respect to the Notes being redeemed or repurchased as provided in this Indenture) or accrued and
unpaid interest, if any, on any Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement
of the payment or delivery of consideration due upon conversion.

 

Article
7

Concerning the Trustee

 

Section
7.01.      Duties and Responsibilities of Trustee.

 

(a)              
Subject to Section 7.01(c), the duties and obligations of the Trustee shall be determined solely by the express provisions
of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically
set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee.

 

    45

     

    

 

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

 

(c)              
In the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person’s own affairs.

 

(d)              
No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action,
its own grossly negligent failure to act or its own willful misconduct, except that:

this subsection shall not be construed to limit the effect of subsection (a) and (b) of this Section;

 

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

 

(iii)            
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance
with the written direction of the Company or the Holders of not less than a majority of the aggregate principal amount of the Notes
at the time outstanding determined as provided in Article 8 relating to the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

 

(iv)           
no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not assured
to it.

 

 

 

Section
7.02.      Certain Rights of the Trustee.

 

(a)

faith to be genuine and to have been signed or presented by the proper party or parties.

 

    46

to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company.

 

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

The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document,
but the Trustee, in its discretion (but shall have no obligation), may make such further inquiry or investigation into such facts
or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled,
at a reasonable time on any Business Day, to examine the books, records and premises of the Company, personally or by agent or
attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation.

(i)                
In no event shall the Trustee be liable for any special, indirect, punitive or consequential loss or damage of any kind

damage and regardless of the form of action.

 

(j)                
The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either
(1) a Default or Event of Default under Section 6.01(a) or (b) of this Indenture has occurred or (2) written notice of such Default
or Event of Default shall have been given to a Responsible Officer of the Trustee by the Company or by any Holder of the Notes
at the Corporate Trust Office of the Trustee and such notice references the Notes and this Indenture. In the absence of receipt
of such notice, the Trustee may conclusively assume that there is no Default or Event of Default.

 

    47

     

    

 

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

prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed)
may, in the absence of bad faith on its part, conclusively rely upon an Officer’s Certificate.

 

(m)            
If any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice
to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such
event occurred.

 

(n)            
The rights and protections afforded to the Trustee under this Indenture, including, without limitation, its right to be
indemnified, shall also be afforded to the Trustee in each of its capacities hereunder, and each agent, custodian and other Person
employed to act hereunder.

Subject to this Article 7, if an Event of Default occurs and is continuing, the Trustee shall be under no obligation to
exercise any of the trust or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to
this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against
any loss, liability, claim and expense which might be incurred by it in compliance with such request or direction.

 

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

Section
7.04.      Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note
Registrar May Own Notes. The Trustee, any Paying
Agent, any Conversion Agent, the Custodian, Bid Solicitation Agent or Note Registrar, in its individual or any other capacity,

time by the Company and the Trustee.

appointed by or any agent of the Trustee, by reason of taking possession of any Common Stock or any part thereof or any other reason
or on any basis whatsoever, be liable to account for anything expect actual receipts or be liable for any loss or damage arising
from a realization of the Common Stock or any part thereof or from any act, default or omission in relation to the Common Stock
or any part thereof or from any exercise or non-exercise by it of any power, authority or discretion conferred upon it in relation
to the Common Stock or any part thereof unless such loss or damage shall be caused by its own fraud or gross negligence. The Trustee
shall not have any responsibility or liability arising from the fact that the Common Stock may be held in safe custody by a custodian.
The Trustee assumes no responsibility for the validity, sufficiency or enforceability of the Common Stock purported to be created
by any document. In addition, the Trustee has no duty to monitor the performance by the Company of its obligations to the Trustee
nor is the Trustee obliged (unless indemnified and/or secured (including by way of prefunding to its satisfaction) to take any
other action which may involve the Trustee in any personal liability or expense).

 

Section
7.06.      Compensation and Expenses of Trustee.
The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall receive such compensation for
all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation
of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay
or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture in any capacity hereunder (including the reasonable compensation and

disbursement or advance as shall have been caused by its gross negligence or willful misconduct. 

 

The Company covenants and agrees to indemnify
the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and
its agents and any authenticating agent for, and to hold them harmless from and against and reimburse the Trustee for, any claims,
obligations, losses, liabilities, expenses (including attorneys’ fees and expenses), damages, injuries (to person, property,
or natural resources), penalties, stamp or other similar taxes, actions, suits, judgments of whatever kind or nature regardless
of their merit, demanded, asserted, claimed or incurred by or against either of them directly or indirectly relating to, or arising
from, claims against the Trustee incurred without gross negligence or willful misconduct on the part of the Trustee, its officers,
directors, agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection
with the acceptance or administration of this Indenture and the enforcement of this Indenture (including this Section 7.06) or
in any other capacity hereunder, including the costs and expenses of defending themselves against any claim (whether asserted by
the Company, a Holder or any other Person) of liability in the premises. The obligations of the Company under this Section 7.06
to compensate or indemnify the Trustee and to pay or reimburse the Trustee shall be secured by a senior claim to which the Notes
are hereby made subordinate on all money or property held or collected by the Trustee, except, subject to the effect of Section
6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment
of any amounts due under this Section 7.06 shall not be made expressly subordinate to any other liability or indebtedness of the
Company. The obligations of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture,
final payment of the Notes and the earlier resignation or removal of the Trustee. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall
extend to the officers, directors, agents and employees of the Trustee.

 

    49

     

    

 

Without prejudice to any other rights available
to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses or render services
after an Event of Default specified in Section 6.01(h) occurs with respect to the Company, the expenses and the compensation for
the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

 

Section
7.07.       [Reserved] 

 

Section
7.08.      Eligibility of Trustee.
There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act (as
if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000.
If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or
examining authority, then for the purposes of this Section 7.08, the combined capital and surplus of such Person shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article 7.

 

Section
7.09.      Resignation or Removal of Trustee.
The Trustee may at any time resign by giving 30 days prior written notice of such resignation to the Company and by mailing notice
thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation,
the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of
Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If
no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice
of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders,
petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor trustee, or any
Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11,
on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such
court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

 

    50

     

    

 

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

 

(i)               
the Trustee shall fail to comply with Section 7.13 within a reasonable time after written request therefor by the Company
or by any Holder who has been a bona fide Holder of a Note or Notes for at least six (6) months;

 

(ii)              
the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after
written request therefor by the Company or by any such Holder, or

 

(iii)             
the Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or
of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs
for the purpose of rehabilitation, conservation or liquidation,

 

then, in any such case, the Company may by a Board
Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board
of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee,
or, subject to the provisions of Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months
may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction, at the expense of the
Company, for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

 

(b)              
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time, with 30 days
prior written notice to the Trustee and the Company, remove the Trustee and nominate a successor trustee that shall be deemed appointed
as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto. If no successor
trustee shall have been so appointed and have accepted appointment within 30 days after removal of the Trustee by the Holders,
the Trustee may, at the expense of the Company, upon ten Business Days’ notice to the Company and the Holders, petition any
court of competent jurisdiction for the appointment of a successor trustee.

 

(c)              
Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this
Section 7.09 shall become effective upon (i) payment of all fees and expenses owing to the Trustee and (ii) acceptance of appointment
by the successor trustee as provided in Section 7.10.

 

    51

     

    

 

Section
7.10.      Acceptance by Successor Trustee.
Any successor trustee appointed as provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein;
but, nevertheless, on the written request of the Company or of the successor trustee, the predecessor trustee shall, upon payment
of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such
successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the
Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are
hereby made subordinate on all money or property held or collected by such trustee as such pursuant to this Indenture, except
for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions
of Section 7.06.

 

No successor trustee shall accept appointment
as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions
of Section 7.08.

 

Upon acceptance of appointment by a successor
trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense
of the Company shall send or cause to be sent notice of the succession of such trustee hereunder to the Holders at their addresses
as they shall appear on the Note Register. If the Company fails to mail such notice within ten days after acceptance of appointment
by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

 

Section
7.11.      Succession by Merger, Etc.
Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any
corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any
corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the
administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper
or any further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding
to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible
under the provisions of Section 7.08.

 

In case at the time such successor
to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent
appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall
not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate
such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases
such certificates of authentication shall have the full force which it is anywhere in the Notes or in this Indenture provided that
the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate
of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to
its successor or successors by merger, conversion or consolidation.

 

    52

     

    

 

Section
7.12.      Trustee’s Application for Instructions from the Company.
Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be
taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at
the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture
and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable
for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the
date specified in such application (which date shall not be less than three Business Days after the date any Officer actually
receives such application, unless any such Officer shall have consented in writing to any earlier date), unless, prior to taking
any such action (or the date of effectiveness in the case of any omission), the Trustee shall have received written instructions
in accordance with this Indenture in response to such application specifying the action to be taken or omitted.

 

Section
7.13.      Conflicting Interests of Trustee.
If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of this Indenture.

 

Article

Concerning the Holders

 

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

 

Section
8.02.      Proof of Execution by Holders.
Subject to the provisions of Section 7.01 and Section 7.02, proof of the execution of any instrument by a Holder or its agent
or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee
or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate
of the Note Registrar.

 

    53

     

    

 

Section
8.03.      Who Are Deemed Absolute Owners.
The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the
Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such
Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by
any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal
of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes;
and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be affected
by any notice to the contrary. The sole registered holder of a Global Note shall be the Depositary or its nominee. All such payments
or deliveries so made to any Holder, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock
so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable upon any such
Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder of a beneficial
interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or
any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note
in certificated form in accordance with the provisions of this Indenture.

 

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

 

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

any amendment, supplement or waiver that adversely affects the Trustee’s own rights, duties or immunities under this Indenture
or otherwise.

 

Any amendment, supplement or waiver
to this 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.
Except as provided in Section 10.01 and in this Section 10.02, the Company and the Trustee may from time to time and at any time
amend or supplement this Indenture and the Notes with the consent (evidenced as provided in Article 8) of the Holders of at least
a majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including,
without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes) and any existing
Default or Event of Default (other than (i) a Default or Event of Default in the payment of the principal (including any Redemption
Price and any Fundamental Change Repurchase Price, if applicable ) of, or accrued and unpaid interest, if any, on the Notes, except
a payment default resulting from an acceleration that has been rescinded, and (ii) a Default or Event of Default as a result of
a failure by the Company to deliver the consideration due upon conversion of the Notes) or compliance with any provision of this
Indenture or the Notes may be waived with the consent (evidenced as provided in Article 8) of the Holders of at least a majority
of the aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without
limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes); provided, however,
that, without the consent of each Holder of an outstanding Note affected, no such amendment shall:

 

(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;

(e)

Upon the written request of the Company,
and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee
shall join with the Company in the execution of such amendment, supplement or waiver unless such amendment, supplement or waiver
adversely affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee
may in its discretion, but shall not be obligated to, enter into such amendment, supplement or waiver.

 

Holders do not need under this Section 10.02
to approve the particular form of any proposed amendment, supplement or waiver of this Indenture. It shall be sufficient if such
Holders approve the substance thereof. After any such amendment, supplement or waiver becomes effective, the Company shall send
to the Holders a notice briefly describing such amendment, supplement or waiver, unless a Current Report on Form 8-K (or successor
form thereto) is filed by the Company describing the amendment, supplement or waiver. 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 amendment, supplement or waiver.

 

Section
10.03.    Effect of Amendment, Supplement and Waiver.
Upon the execution of any amendment, supplement or waiver of this Indenture pursuant to the provisions of this Article 10, this

provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter
provided for in such amendment, supplement or waiver. If the Company or the Trustee shall so determine, new Notes so modified
as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any
such amendment, supplement or waiver may, at the Company’s expense, be prepared and executed by the Company, authenticated
by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.11) and delivered in exchange
for the Notes then outstanding, upon surrender of such Notes then outstanding. Failure to make the appropriate notation or issue
a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Consolidation, Merger and Sale

 

Section
11.01.    Company May Consolidate, Etc. on Certain Terms.

 

(a)              
The Company shall not consolidate with or merge with or into or otherwise combine with another Person, or sell, lease or
otherwise transfer or dispose of all or substantially all of the Company’s and its Subsidiaries’ consolidated assets,
taken as a whole, to another Person other than one of the Company’s Wholly-Owned Subsidiaries, unless:

 

(i)               
the Company is the surviving Person or the resulting, surviving or transferee Person (if not the Company) (the “Successor
Company”) is a Person organized and existing under the laws of any Permitted Jurisdiction, and such Person (if not the
Company) expressly assumes by supplemental indenture all of the Company’s obligations under the Notes and this Indenture;
and

 

(ii)              
immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing
under this Indenture.

 

    58

     

    

 

(b)              
Upon any such consolidation, merger, combination or sale, lease or other transfer or disposition 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
and/or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance
of all of the covenants and conditions of this Indenture and the Notes to be performed by the Company, such Successor Company shall
succeed to, and may exercise every right and power of and be substituted for, the Company, with the same effect as if it had been
named herein as the party of the first part, and the Company shall be discharged from its obligations under the Notes and this
Indenture, except in the case of a lease of all or substantially all assets. Such Successor Company thereupon may cause to be signed,
and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of
the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate
and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by
an Officer of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to
be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as
though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, combination
or sale, transfer or disposition (but not in the case of a lease), upon compliance with this Article 11, the Person named as the
 “Company” in the first paragraph of this Indenture shall be released from its liabilities as obligor and maker of the

(c)              
For purposes of the foregoing, any sale, lease or other transfer or disposition of the assets of one or more of the Company’s
Subsidiaries that would, if the Company had held such assets directly, have constituted the sale, lease or other transfer or disposition
of all or substantially all of the Company’s consolidated assets, taken as a whole, will be treated as such under this Indenture.

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 in an Authorized Denomination 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 March 15, 2023 under the circumstances and during the periods set forth in Section 14.01(b);

 

(ii)             
on or after March 15, 2023, at any time prior to the close of business on the second Scheduled Trading Day immediately preceding
the Maturity Date;

 

in each case, at an initial conversion rate of 13.8672
shares of Common Stock (subject to adjustment as provided in Section 14.04 and, if applicable, Section 14.03, the “Conversion
Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 14.02, the “Conversion
Obligation”). Notwithstanding the foregoing, under no circumstances may the Conversion Price be less than the par value
per share of Common Stock.

 

    60

     

    

 

 

(b)              
(i) Prior to the close of business on the Business Day immediately preceding March 15, 2023, a Holder may surrender all
or any portion of its Notes in an Authorized Denomination for conversion at any time during the five Business Day period after
any ten 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 the procedures and conditions described
in 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 per share of the Common Stock and the Conversion Rate on each such Trading Day, subject to compliance with the following
procedures and conditions concerning the Bid Solicitation Agent’s obligation to make a Trading Price determination.

 

(A)            
The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000
principal amount of the Notes unless the Company has requested such determination, and the Company shall have no obligation to
make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the
Trading Price) unless a Holder of at least $1,000,000 in aggregate principal amount of Notes requests in writing that the Company
makes such a determination and 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 per share of the Common Stock and the Conversion
Rate on such Trading Day. At such time, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine,
or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount
of the Notes beginning on the Trading Day following the receipt of such evidence 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 per share
of the Common Stock and the Conversion Rate on such Trading Day.

 

(B)             
If the Trading Price condition has been met, the Company shall promptly so notify the Holders, the Trustee and the Conversion
Agent (if other than the Trustee) in writing. If, at any time after the Trading Price condition 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 per share of
the Common Stock and the Conversion Rate on such Trading Day, the Company shall promptly so notify the Holders, the Trustee and
the Conversion Agent (if other than the Trustee) in writing.

 

(C)             
If the Company does not, when it is required to, instruct the Bid Solicitation Agent to (or, if the Company is acting as
Bid Solicitation Agent, it does not) obtain bids, or if the Company gives such instruction to the Bid Solicitation Agent and the
Bid Solicitation Agent fails to make such determination (or, if the Company is acting as Bid Solicitation Agent, it fails to make
such determination), then, in either case, the Trading Price per $1,000 principal amount of the Notes shall be deemed to be less
than 98% of the product of the Last Reported Sale Price per share of the Common Stock and the Conversion Rate on each Trading Day
of such failure.

 

    61

     

    

 

(ii)             
If, prior to the close of business on the Business Day immediately preceding March 15, 2023, the Company elects to:

 

(A)            
issue to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a
shareholder rights plan in connection with the initial adoption by the Company, so long as such rights have not separated from
the shares of Common Stock and are not exercisable until the occurrence of a triggering event) 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 per share 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, options
or warrants to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board
of Directors, exceeding 10% of the Last Reported Sale Price per share of the Common Stock on the Trading Day immediately preceding
the date of announcement of such distribution,

 

then, in either case, the Company shall notify all
Holders of the Notes at least 50 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution; provided,
however, that if the Company elects Physical Settlement for conversions that occur during the period from the date the Company
provides such notice to the date the related conversion right expires, the Company shall provide notice at least 10 Scheduled Trading
Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, the Holders may surrender
all or any portion of their Notes in an Authorized Denomination 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.

 

No Holder may convert any of its
Notes pursuant to this Section 14.01(b)(ii) if such Holder otherwise participates in such issuance or distribution, at the same
time and upon the same terms as holders of Common Stock and as a result of holding the Notes, without having to convert its Notes,
as if it held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed
in thousands) of Notes held by such Holder.

 

    62

     

    

 

(iii)           
If, prior to the close of business on the Business Day immediately preceding March 15, 2023:

 

(A)            
a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs; or

 

(B)             
the Company is a party to a consolidation, merger or other combination, statutory share exchange, or sale, lease or other
transfer or disposition of all or substantially all of the Company’s and the Company’s Subsidiaries’ consolidated
assets, taken as a whole to any Person other than one of the Company’s Wholly-Owned Subsidiaries (in each case, other than
solely for the purpose of changing the Company’s jurisdiction of organization that (I) does not constitute a Fundamental
Change or a Make-Whole Fundamental Change and (II) results in a reclassification, conversion or exchange of outstanding shares
of our Common Stock solely into shares of common stock of the surviving entity and such common stock becomes reference property
for the Notes) that occurs, in each case, pursuant to which the Common Stock would be converted into cash, securities or other
assets (including any combination thereof),

 

all or any portion of a Holder’s Notes in an
Authorized Denomination may be surrendered for conversion at any time (x) from or after the effective date of such transaction
until 35 Trading Days after the actual effective date of such transaction or, (y) if such transaction also constitutes a Fundamental
Change, until the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date (other
than, for purposes of this clause (y), a Fundamental Change in connection with which the Company validly invokes the Adequate Cash
Conversion Provisions, in which case the conversion period shall be that specified in clause (x)).

 

The Company shall notify Holders,
the Trustee and the Conversion Agent (if other than the Trustee) in writing as promptly as practicable following the date the Company
publicly announces such transaction and will use commercially reasonable efforts to provide such notice, if practicable, no later
than the actual effective date of such transaction.

 

(iv)            
Prior to the close of business on the Business Day immediately preceding March 15, 2023, a Holder may surrender all or any
portion of its Notes in an Authorized Denomination for conversion at any time during any calendar quarter commencing after the
calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the Last Reported Sale Price of the Common
Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the
last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each
applicable Trading Day.

 

    63

     

    

 

(v)              
If the Company calls the Notes for redemption pursuant to Section 16.01, Holders may exchange any or all of their Notes
called for redemption at any time from, and including, the date of the Notice of Tax Redemption until the close of business on
the second Scheduled Trading Day immediately preceding the Tax Redemption Date, or, if the Company fails to pay the Redemption
Price, such later date on which the Company pays or duly provides for the Redemption Price.

 

(c)              
Notwithstanding any other provision of this Indenture or the Notes, no Holder of the Notes will be entitled to receive shares
of Common Stock upon conversion of such Notes to the extent (but only to the extent) that such receipt would cause a violation
of the Ownership Limitation. Any purported delivery of shares of Common Stock upon conversion of Notes will be void and have no
effect to the extent (but only to the extent) that such delivery would result in a violation of the Ownership Limitation. If any
delivery of shares of Common Stock owed to a Holder upon conversion of Notes is not made, in whole or in part, as a result of the
limitations described in this paragraph, the Company’s obligation to make such delivery shall not be extinguished, and the
Company shall deliver such shares as promptly as practicable after the applicable Holder gives notice to the Company and the Company
determines that such delivery would not result in a violation of the Ownership Limitation.

 

Section
14.02.  Conversion Procedure; Settlement Upon Conversion.

 

(a)              
Subject to this Section 14.02, Section 14.03(b) and Section 14.07(a), upon conversion of any Note, the Company shall, at
its election, pay or deliver, as the case may be, to the converting Holder, in full satisfaction of its Conversion Obligation,
cash (“Cash Settlement”), shares of the Common Stock, together with cash, if applicable, in lieu of delivering
any fractional share of Common Stock in accordance with Section 14.02(i) (“Physical Settlement”), or a combination
of cash and shares of the Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common
Stock in accordance with Section 14.02(i) (“Combination Settlement”), as set forth in this Section 14.02.

 

(i)                
All conversions for which the relevant Conversion Date occurs on or after March 15, 2023 and all conversions occurring after
the date the Company issues a Notice of Tax Redemption, and prior to the close of business on the second Scheduled Trading Day
immediately preceding the related Tax Redemption Date, shall be settled using the same Settlement Method (including the same relative
proportion of cash and/or shares of the Common Stock). Except for any conversions for which the relevant Conversion Date occurs
on or after March 15, 2023 or after the date of the issuance of a Notice of Tax Redemption and prior to the close of business on
the second Scheduled Trading Day immediately preceding the related Tax Redemption Date, the Company shall use the same Settlement
Method (including the same relative proportion of cash and/or shares of the Common Stock) 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. By notice to Holders of the Notes, the Company may, prior to March 15, 2023, at its option, irrevocably elect
a Settlement Method and/or a Specified Dollar Amount (or a minimum Specified Dollar Amount), or eliminate the right to elect a
Settlement Method, for all Conversion Dates occurring subsequent to delivery of such notice.

 

    64

     

    

 

(ii)             
If the Company elects a Settlement Method, the Company shall deliver notice to Holders through the Conversion Agent of such
Settlement Method the Company has selected no later than the close of business on the Trading Day immediately following the related
Conversion Date (or (A) in the case of any conversions for which the relevant Conversion Date occurs on or after March 15, 2023,
no later than March 15, 2023 or (B) in the case of any conversions occurring after the date of issuance of a Notice of Tax Redemption
and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Tax Redemption Date, in
such Notice of Tax Redemption). If the Company does not timely elect a Settlement Method, the Company shall no longer have the
right to elect Cash Settlement or Physical Settlement with respect to that Conversion Date 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. If the Company has timely elected Combination Settlement in respect of any conversion but does
not timely notify the Conversion Agent of the Specified Dollar Amount per $1,000 principal amount of Notes, the Specified Dollar
Amount shall be deemed to be $1,000.

 

(iii)           
The cash, shares of Common Stock or combination of cash and shares of Common Stock payable or deliverable by the Company
in respect of any conversion of Notes (the “Settlement Amount”) shall be computed by the Company as follows:

 

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

 

(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 40 consecutive VWAP 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, to the converting Holder 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
40 consecutive VWAP Trading Days during the related Observation Period (plus cash in lieu of any fractional share of Common Stock
issuable upon conversion).

 

    65

     

    

 

If more than one Note shall be surrendered
for conversion at any 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 so surrendered.

 

(iv)            
The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the
Company promptly following the last VWAP Trading Day of the related Observation Period. Promptly after such determination of the
Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and, if applicable, the amount of cash payable in
lieu of 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, if applicable, the amount of
cash payable in lieu of 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)              
(i) To convert a beneficial interest in a Global Note (which conversion is irrevocable), the holder of such beneficial interest
must:

 

(A)            
comply with the Applicable Procedures;

 

(B)             
if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set forth in Section 14.02(d)
and Section 14.02(e); and

 

(C)             
if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled
as set forth in Section 14.02(g); and

 

(ii)             
To convert a Certificated Note, the Holder must:

 

(A)            
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”) and such Note to the Conversion Agent;

 

(B)             
if required, furnish appropriate endorsements and transfer documents;

 

    66

     

    

 

(C)             
if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set forth in Section 14.02(d)
and Section 14.02(e); and

 

(D)            
if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled
as set forth in Section 14.02(g).

 

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
or, if notice on such date is not feasible given the nature of the conversion, promptly thereafter.

 

If a Holder has already delivered
a Fundamental Change Repurchase Notice with respect to a Note, such Holder may not surrender such Note for conversion until such
Holder has validly withdrawn such Fundamental Change Repurchase Notice (or, in the case of a Global Note, has complied with the
Applicable Procedures with respect to such a withdrawal) in accordance with the terms of Section 15.03. If a Holder has already
delivered a Fundamental Change Repurchase Notice, such Holder’s right to withdraw such notice and convert the Notes that
are subject to repurchase will terminate at the close of business on the Business Day immediately preceding the relevant Fundamental
Change Repurchase Date.

 

(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 Section 14.02(b).

 

Subject to the next paragraph
and the provisions of Section 14.03(b) and Section 14.07(a), the Company shall pay or deliver, as the case may be, the Settlement
Amount due in respect of the Conversion Obligation on:

 

(i)              
the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement; or

 

(ii)             
the second Business Day immediately following the last VWAP Trading Day of the relevant Observation Period, if the Company
elects Cash Settlement or if the Company elects or is deemed to elect Combination Settlement.

 

If any shares of Common Stock
are due to converting Holders, the Company shall issue or cause to be issued, and deliver to such Holder, or such Holder’s
nominee or nominees, certificates or a book-entry transfer through the Depositary, as the case may be, for the full number of shares
of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

 

(d)              
In case any Certificated Note shall be surrendered for partial conversion, in an Authorized Denomination, the Company shall
execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder so surrendered a new Note or
Notes in Authorized Denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without
payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient
to cover any 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.

 

    67

     

    

 

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

 

(f)               
Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian of the Global Note at the direction of
the Trustee, shall make a notation in the books and records of the Trustee and Depositary 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.

 

(g)              
Upon conversion of a Note, the converting Holder shall not receive any separate cash payment representing accrued and unpaid
interest, if any, except as set forth in the paragraph below. The Company’s payment or delivery, as the case may be, of the
Settlement Amount upon conversion of any Note 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 canceled,
extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid
interest shall be deemed to be paid first out of the cash paid upon such conversion.

 

Notwithstanding the immediately
preceding paragraph, if Notes are converted after the close of business on a Regular Record Date for the payment of interest, but
prior to the open of business on the immediately following Interest Payment Date, Holders of such Notes at the close of business
on such Regular Record Date shall 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 on the corresponding Interest Payment Date (regardless of whether the converting
Holder was the Holder of record on the corresponding Regular Record Date); provided that no such payment need be made:

 

    68

     

    

 

(i)              
if the Notes are surrendered for conversion following the Regular Record Date immediately preceding the Maturity Date;

 

(ii)             
if the Company has called the Notes for Tax Redemption on a Tax Redemption Date that is after a Regular Record Date and
on or prior to the Business Day immediately following the corresponding Interest Payment Date;

 

(iii)            
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

 

(iv)            
to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

 

Therefore, for the avoidance of
doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date, any Fundamental Change Repurchase
Date and any Tax Redemption as described in clauses (ii) and (iii) above shall receive and retain the full interest payment due
on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been converted following
such Regular Record Date.

 

(h)              
The Person in whose name any shares of Common Stock delivered upon conversion is registered shall become the holder of record
of such shares as of the close of business on (i) the relevant Conversion Date if the Company elects Physical Settlement or (ii)
the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement.
Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion; provided that
(a) the converting Holder shall have the right to receive the Settlement Amount due upon conversion and (b) in the case of a conversion
between a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the close of business on
such Regular Record Date shall have the right to receive the interest payable on such Interest Payment Date, in accordance with
Section 14.02(g).

 

(i)                
The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash
in lieu of any fractional share of Common Stock issuable upon conversion in an amount based on (i) the Daily VWAP on the relevant
Conversion Date if the Company elects Physical Settlement or (ii) the Daily VWAP on the last VWAP Trading Day of the relevant Observation
Period if the Company elects or is deemed to elect Combination Settlement. For each Note surrendered for conversion, if the Company
has elected (or is deemed to elect) 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, if applicable,
any fractional share remaining after such computation shall be paid in cash.

 

Section
14.03.  Increase in Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change or
a Tax Redemption. (a) If (i) the Event Effective
Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (ii) the Company delivers a Notice of Tax Redemption
and, in either case a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change or Notice of Tax
Redemption, the Company shall, under the circumstances described in this Section 14.03, 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 in this Section 14.03. 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 (or, in the case of a Global Note, the relevant notice
of conversion in accordance with the Applicable Procedures) is received by the Conversion Agent during the period from the open
of business on the Event Effective Date of the Make-Whole Fundamental Change to the close of business on the Business Day immediately
preceding 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 (A) the proviso in clause (b) of the definition thereof or (B) the Adequate Cash Conversion Provisions,
the 35th Trading Day immediately following the Event Effective Date of such Make-Whole Fundamental Change). A conversion of Notes
will be deemed for these purposes to be “in connection with” such Notice of Tax Redemption if the relevant Notice
of Conversion of the Notes (or, in the case of a Global Note, the relevant notice of conversion in accordance with the Applicable
Procedures) is received by the Conversion Agent during the period from the open of business on the date of the Notice of Tax Redemption
to the close of business on the second Scheduled Trading Day immediately preceding the related Tax Redemption Date or, if the
Company fails to pay the Redemption Price, such later date on which we pay the Redemption Price.

 

    69

     

    

 

(b)              
Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or Notice of Tax Redemption, the
Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement
in accordance with Section 14.02 (after giving effect to any increase in the Conversion Rate required by this Section 14.03); provided,
however, that, if the consideration for the Common Stock in any Make-Whole Fundamental Change described in clause (b) of
the definition of Fundamental Change is composed entirely of cash, for any conversion of Notes following the Event 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 (i) the Conversion Rate (including
any increase to reflect the Additional Shares as described in this Section 14.03), multiplied by (ii) such Stock Price.
In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the second Business Day following the
Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing
of the Event Effective Date of any Make-Whole Fundamental Change and, no later than five Business Days after such Event Effective
Date, (A) issue a press release announcing such Event Effective Date or disclose the Event Effective Date in a Current Report on
Form 8-K and (B) post the Event Effective Date on the Company’s website (the “Make-Whole Fundamental Change Company
Notice”).

 

    70

     

    

 

(c)              
The number of Additional Shares, if any, by which the Conversion Rate shall be increased in connection Make-Whole Fundamental
Change or Notice of Tax Redemption shall be determined by reference to the table below, based on:

 

(i)              
in the case of a Make-Whole Fundamental Change the date on which the Make-Whole Fundamental Change occurs or becomes effective
or, in the case of a Tax Redemption, the date of the Notice of Tax Redemption (the “Event Effective Date”) and

 

(ii)             
in the case of a Make-Whole Fundamental Change, the price paid (or deemed to be paid) per share of the Common Stock in the
Make-Whole Fundamental Change, as described in the succeeding paragraph or, in the case of a Tax Redemption, the average of the
Last Reported Sale Prices per share of Common Stock over the five Trading Day period ending on, and including, the Trading Day
immediately preceding the date of such Notice of Tax Redemption, as the case may be (in each case, the “Stock Price”).

 

If the holders of the Common Stock receive 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 per share of the Common
Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Event 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 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 is otherwise adjusted. The adjusted Stock Prices shall equal (i) the Stock Prices applicable immediately prior to such adjustment,
multiplied by (ii) 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 Event Effective Date set forth below:

The exact Stock Price or Event
Effective Date may not be set forth in the table above, in which case:

 

(i)              
if the Stock Price is between two Stock Prices in the table or the Event Effective Date is between two Event Effective Dates
in the table, the number of Additional Shares by which the Conversion Rate shall be increased 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
Event Effective Dates in the table above, as applicable, based on a 365- or 366-day year, as the case may be;

 

(ii)             
if the Stock Price is greater than $350.00 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above), the Conversion Rate shall not be increased; and

 

(iii)            
if the Stock Price is less than $57.69 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the column headings of the table above), the Conversion Rate shall not be increased.

 

Notwithstanding the foregoing,
in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 17.3340 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 a
share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result
of holding the Notes, in any of the transactions described in this Section 14.04, without having to convert their Notes, as if
they held a number of shares of Common Stock equal to (i) the Conversion Rate, multiplied by (ii) the principal amount
(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:

 

	CR1 = CR0 × 	OS1 	 
	OS0	 

 

where,

 

    72

     

    

 

	 	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;

 

	 	CR1	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or effective date, as applicable;

 

	 	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective
date, as applicable, before giving effect to such dividend, distribution, share split or share combination; and

 

	 	OS1	=	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 Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share 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:

 

	CR1 = CR0 × 	OS0
    + X	 
	OS0 + Y	 

 

where,

 

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

 

	 	CR1	=	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;

 

    73

     

    

 

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

 

		Y	=	the number of shares of Common Stock equal to (i) the aggregate price payable to exercise such rights, options or warrants, divided
by (ii) the average of the Last Reported Sale Prices per share 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 such rights, options or warrants are not
exercised prior to their expiration or shares of Common Stock are not delivered after the exercise or 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,
effective as of the date the Company’s Board of Directors determines not to issue such rights, options or warrants, 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 Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders of Common Stock to subscribe
for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices per share 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, 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)             
rights issued under a shareholder rights plan (except as set forth in this Section 14.04(c));

 

    74

     

    

 

(iii)           
dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 14.04(d);

 

(iv)           
any dividends and distributions in connection with a Specified Corporate Event described in Section 14.07; and

 

(v)            
Spin-Offs as to which the provisions set forth in this Section 14.04(c) shall apply

 

(any of such shares of Capital Stock,
evidences of indebtedness, assets, property, rights, options or warrants to acquire Capital Stock or other securities of the Company,
the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

 

	CR1 = CR0 × 	      SP0      	 
	SP0 – FMV	 

 

where,

 

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

 

		CR1	=	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 per share 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 so distributed 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, effective as of the date the Company’s
Board of Directors determines not to pay or make such distribution, to be 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
that 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.

 

    75

     

    

 

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:

 

	CR1 = CR0 × 	FMV0
    + MP0	 
	MP0	 

 

where,

 

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

 

		CR1	=	the Conversion Rate in effect immediately after the end of the Valuation Period;

 

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

 

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

 

The increase to the Conversion
Rate under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period; provided
that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date
occurs during the Valuation Period, the references to “10” in the preceding paragraph shall be deemed to be replaced
with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in
determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement
is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation
Period, the references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of
Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate
as of such Trading Day. In addition, if the Ex-Dividend Date for such Spin-Off is after the 10th Trading Day immediately preceding,
and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th”
in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion, with such lesser
number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading
Day of such Observation Period. If such Spin-Off does not occur, the Conversion Rate shall be decreased, effective as of the date
the Company’s Board of Directors determines not to consummate such Spin-Off, to be the Conversion Rate that would then be
in effect if such distribution had not been declared, effective as of the date on which the Board of Directors determines not to
consummate such Spin-Off.

 

    76

     

    

 

For purposes of this Section 14.04(c)
(and subject in all respect to Section 14.11), rights, options or warrants distributed by the Company to all holders of the Common
Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially
or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger
Event”):

 

(i)              
are deemed to be transferred with such shares of the Common Stock;

 

(ii)             
are not exercisable; and

 

(iii)            
are also issued in respect of future issuances of the Common Stock,

 

shall be deemed not to have been distributed for purposes
of this Section 14.04(c) (and no adjustment to the Conversion Rate under this Section 14.04(c) will be required) until the occurrence
of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate
adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.04(c). If any such right, option or
warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to
events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences
of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution
and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options
or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition,
in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of
the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution
amount for which an adjustment to the Conversion Rate under this Section 14.04(c) was made:

 

(A)            
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

 

    77

     

    

 

(B)             
in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders
thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

 

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

 

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

 

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

 

then:

 

(A)            
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

 

(B)             
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, the Conversion Rate
shall be adjusted based on the following formula:

 

	CR1 = CR0 × 	    SP0    	 	 
	SP0 − C	 

 

    78

     

    

 

where,

 

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

 

		CR1	=	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 per share of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such
dividend or distribution; and

 

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

 

Any increase made 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 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 in effect immediately prior to the open of business on the Ex-Dividend
Date for such cash dividend or distribution.

 

(e)              
If the Company or any of its Subsidiaries makes 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 per share 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 (such date, the “Expiration Date”), the Conversion Rate shall be increased based on the following
formula:

 

	CR1 = CR0 × 	AC + (SP1 × OS1)	 
	OS0 × SP1

 

where,

 

		CR0	=	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including,
the Trading Day next succeeding the Expiration Date;

 

    79

     

    

 

		CR1	=	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including,
the Trading Day next succeeding the Expiration Date;

 

		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 time (the “Expiration Time”) 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);

 

		OS1	=	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to the purchase of
all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

 

		SP1	=	the average of the Last Reported Sale Prices per share of the Common Stock over the 10 consecutive Trading Day period commencing
on, and including, the Trading Day next succeeding the Expiration Date.

 

The increase to the Conversion
Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and including,
the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion
of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately
following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10”
or “10th” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have
elapsed between such Expiration Date of such tender or exchange offer and the Conversion Date in determining the Conversion Rate
and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading
Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following,
and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10”
or “10th” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have
elapsed between the Expiration Date of such tender or exchange offer and such Trading Day in determining the Conversion Rate as
of such Trading Day. In addition, if the Trading Day next succeeding the Expiration Date of any tender or exchange offer is after
the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes,
references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced,
solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading
Day next succeeding the Expiration Date of such tender or exchange offer to, and including, last Trading Day of such Observation
Period.

In the event that the Company
or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer,
but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases
are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such
tender offer or exchange offer had not been made or had been made only in respect of the purchases that have been effected.

 

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

 

(g)              
All calculations and other determinations under this Article 14 shall be made by the Company and all adjustments to the
Conversion Rate shall be made to the nearest one-ten thousandth (1/10,000th) of a share. Notwithstanding anything in this Article
14 to the contrary, the Company shall not be required to adjust the Conversion Rate unless the adjustment would result in an increase
or decrease of at least 1.0% to the Conversion Rate. However, the Company shall carry forward, and take into account in any future
adjustment, any adjustments that are less than 1.0% of the Conversion Rate, and make such carried-forward adjustments, regardless
of whether the aggregate amount of such adjustments is less than 1.0% (a) on the effective date of any Fundamental Change or the
Event Effective Date of a Make-Whole Fundamental Change, (b) on the Conversion Date for any Notes (in the case of Physical Settlement),
(c) on each VWAP Trading Day of any Observation Period (in the case of cash settlement or combination settlement) and (d) on the
date of a Notice of Tax Redemption. In no event shall the Conversion Rate be adjusted such that the Conversion Price shall be
less than the par value per share of the Common Stock.

 

(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 the Relevant Stock Exchange, 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 the Relevant Stock Exchange, the Company may also (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 shares of 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 send 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.

 

    81

     

    

 

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

 

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

 

(k)              
The Company shall not adjust the Conversion Rate except as stated in this Indenture, including, for the avoidance of doubt,
for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the
right to purchase shares of Common Stock or such convertible or exchangeable securities. In addition, notwithstanding anything
to the contrary in this Article 14, the Conversion Rate shall not be adjusted:

 

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

 

(ii)               
upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit plan or program of or assumed by the Company or any of its direct or indirect
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 Issue Date;

 

    82

     

    

 

(iv)              
for ordinary course of business stock repurchases that are not tender offers referred to in Section 14.04(e), including
structured or derivative transactions or pursuant to a stock repurchase program approved by the Board of Directors;

 

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

 

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

 

Section
14.05.    Adjustments of Prices.
Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the
Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including, without limitation, an Observation
Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change or a Tax Redemption), the
Board of Directors shall make appropriate adjustments, in good faith, 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, Event Effective
Date or expiration 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.

 

Section
14.06.    Shares to Be Fully Reserved.
The Company shall reserve, on or prior to the date of this Indenture, and from time to time as may be necessary, out of its authorized
but unissued shares, 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, and including the maximum number of Additional Shares that could
be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change).

 

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 a change to par value, or from par value
to no par value, or changes resulting from a subdivision or combination);

 

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

 

(iii)              
any sale, lease or other transfer or disposition to a third party (other than to any of the Company’s Wholly-Owned
Subsidiaries) of all or substantially all of the Company’s and its Subsidiaries’ consolidated assets, taken as a whole;
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 “Specified Corporate Event” and any such stock, other securities, other property
or assets (including cash or any combination thereof), “Reference Property” and the amount of Reference Property
that a holder of one share of the Common Stock immediately prior to such Specified Corporate Event would have been entitled to
receive upon the occurrence of such Specified Corporate Event, a “Unit of Reference Property”), then the Company,
or the successor or purchasing Person, as the case may be, will execute with the Trustee, without the consent of the Holders,
a supplemental indenture providing that, at and after the effective time of the Specified Corporate Event, the right to convert
each $1,000 principal amount of Notes for shares of Common Stock will be changed into a right to convert such principal amount
of Notes for the kind and amount of Reference Property that a holder of a number of shares of the Common Stock equal to the Conversion
Rate immediately prior to such Specified Corporate Event would have been entitled to receive upon such Specified Corporate Event;
provided, however, that at and after the effective time of such Specified Corporate Event:

 

    83

     

    

 

(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 Units of Reference Property that a holder of that number of
shares of Common Stock would have received in such Specified Corporate Event and (III) the Daily VWAP shall be calculated based
on the value of a Unit of Reference Property; provided, however, that if the holders of Common Stock receive only cash
in such Specified Corporate Event, then for all conversions that occur after the effective date of such Specified Corporate Event
(x) the consideration due upon conversion of each $1,000 principal aggregate 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 Specified Corporate Event and (y) the Company shall
satisfy the Conversion Obligation by paying such cash to the converting Holder on the second Business Day immediately following
the Conversion Date.

 

If the Specified Corporate 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 shareholder election), then the Reference Property into which the Notes shall be convertible
shall be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock. The
Company shall notify, in writing, the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the weighted
average as soon as practicable after such determination is made.

 

    84

     

    

 

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 the Reference Property in respect of any such Specified
Corporate Event includes shares of stock, other securities or other property or assets (other than cash) (including any combination
thereof) of an entity other than the Company or the successor or purchasing Person, as the case may be, in such Specified Corporate
Event, then such other entity, if it is a party to such Specified Corporate Event, shall also execute such supplemental indenture,
and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the
right of Holders to require the Company to repurchase their Notes upon a Fundamental Change in accordance with Article 15, as
the Board of Directors shall reasonably consider necessary by reason of the foregoing.

 

(b)              
In the event the Company shall execute a supplemental indenture pursuant to Section 14.07(a), the Company shall furnish
to the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or
other assets (including any combination thereof) that will comprise the Reference Property after any such Specified Corporate
Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly
send notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be sent
to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 Business Days after execution
thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

 

(c)              
If the Notes become convertible into Reference Property, the Company shall notify the Trustee in writing and (i) issue
a press release containing the relevant information or disclose the relevant information in a Current Report on Form 8-K and (ii)
post such information on the Company’s website.

 

(d)              
The Company shall not become a party to any Specified Corporate Event unless its terms are consistent with this Section
14.07. None of the foregoing provisions shall affect the right of a Holder 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 Specified Corporate Event.

 

(e)              
The above provisions of this Section shall similarly apply to successive Specified Corporate Events.

 

    85

     

    

 

Section
14.08.    Certain Covenants.

 

(a)              
The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be duly authorized, fully paid
and non-assessable and free from all preemptive or similar rights of any securityholder of the Company and, except for any transfer
taxes payable by the Company or a Holder, as the case may be, pursuant to Sections 14.02(d) and 14.02(e), free from all documentary,
stamp or similar issue or transfer taxes, liens and charges as the result of any action by the Company.

 

(b)              
The Company covenants that if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares may be validly
issued upon conversion, the Company shall, to the extent then permitted by the rules and interpretations of the Commission, secure
such registration or approval, as the case may be.

 

(c)              
The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange
or automated quotation system, the Company shall 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 4.07 relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes
after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions,
and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to furnish to 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
(if other than the Trustee) 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 (if other than the Trustee) may conclusively rely, and
the Company agrees to deliver such notices to the Trustee and the Conversion Agent (if other than the Trustee) immediately after
the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b). The parties hereto agree
that all notices to the Trustee or the Conversion Agent under this Article 14 shall be in writing or as otherwise provided herein.

 

    86

     

    

 

Section
14.10.    [Reserved]

 

Section
14.11.    Shareholder Rights Plans.
If the Company has a rights plan in effect upon conversion of the Notes into Common Stock, Holders that convert their Notes shall
receive, in addition to any shares of Common Stock received in connection with such conversion, the appropriate number of rights
under the rights plan, if any, and any certificate representing the share of 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 rights plan, as the same may be amended from time
to time. However, if prior to any conversion, the rights have separated from the shares of Common Stock in accordance with the
provisions of the applicable rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed
to all or substantially all holders of shares of Common Stock, Distributed Property pursuant to Section 14.04(c), subject to readjustment
in the event of the expiration, termination or redemption of such rights.

 

Article
15

Purchase of Notes at Option of Holders

 

Section
15.01.    [Reserved] 

 

Section
15.02.    Repurchase at Option of Holders Upon a Fundamental Change.
(a) If a Fundamental Change occurs at any time prior to the Maturity Date, each Holder shall have the right, at such Holder’s
option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount
thereof that is equal to an Authorized Denomination, on the date (the “Fundamental Change Repurchase Date”)
specified by the Company that is not less than 20 nor more than 35 calendar days following the date of the Fundamental Change
Company Notice (subject to extension to comply with applicable law), at a repurchase price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon to, but not including, 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 purchased pursuant to this Article 15.

 

    87

     

    

 

(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 Certificated Notes, or
in compliance with the Applicable 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 Certificated Notes, to the Paying Agent on or before the close of business on the
Business Day immediately preceding the Fundamental Change Repurchase Date (together with all necessary endorsements for transfer)
at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance
with the Applicable Procedures, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change
Repurchase Price therefor.

 

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

 

A.       in
the case of Certificated Notes, the certificate numbers of the Notes to be delivered for repurchase;

 

B.       the
portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple of $1,000 in excess thereof;
and

 

C.       that
the Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

 

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

 

If a Holder has already delivered
a Fundamental Change Repurchase Notice with respect to a Note, such Holder may not surrender such Note for conversion until such
Holder has validly withdrawn such Fundamental Change Repurchase Notice (or, in the case of a Global Note, has complied with the
Applicable Procedures with respect to such a withdrawal) in accordance with the terms of Section 15.03.

 

    88

     

    

 

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 Business Day after the occurrence of a Fundamental Change, the Company shall provide to all Holders
of Notes and the Trustee and the Paying Agent (if other than the Trustee) a written notice (the “Fundamental Change Company
Notice”) of the occurrence of the Fundamental Change and of the repurchase right at the option of the Holders arising
as a result thereof. Each Fundamental Change Company Notice shall specify:

 

(i)                
the events causing the Fundamental Change;

 

(ii)               
the Event Effective Date of the Fundamental Change;

 

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

 

(iv)              
the Fundamental Change Repurchase Price;

 

(v)               
the Fundamental Change Repurchase Date;

 

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

 

(vii)             
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 this Indenture (or, in the
case of a Global Note, complies with the Applicable Procedures with respect to such a withdrawal); and

 

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

 

Simultaneously with providing
such Fundamental Change Company Notice, the Company shall (A) issue a press release containing such information or disclose the
information in a Current Report on Form 8-K and (B) post such information on the Company’s website.

 

At the Company’s written
request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however,
that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. In such a case, the Company
shall deliver such notice to the Trustee at least three Business Days prior to the date that the notice is required to be given
to the Holders (unless a shorter notice period shall be agreed to by the Trustee), together with an Officer’s Certificate
requesting that the Trustee give such notice.

 

    89

     

    

 

Such notice shall be delivered
to the Trustee, to the Paying Agent (if other than the Trustee) and to each Holder at its address shown in the Note Register (and
to the beneficial owner as required by applicable law) or, in the case of Global Notes, in accordance with the Applicable Procedures.

 

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.

 

(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 Certificated 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 Applicable Procedures 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.

 

(e)              
Notwithstanding anything to the contrary in this Section 15.02, the Company shall not be required to repurchase, or to
make an offer to repurchase, Notes upon a Fundamental Change:

 

(i)                
if a third party makes such an offer in the same manner, at the same time, and otherwise in compliance with the requirements
for an offer made by the Company set forth in this Indenture and such third party purchases all Notes properly surrendered and
not validly withdrawn under its offer in the same manner, at the same time, and otherwise in compliance with the requirements
for an offer made by the Company set forth in this Indenture; or

 

(ii)               
pursuant to clause (b) of the definition thereof (or a Fundamental Change pursuant to clause (a) that also results in a
Fundamental Change pursuant to clause (b)), if (i) such Fundamental Change results in the Notes becoming convertible (pursuant
to the provisions described in Section 14.07) into an amount of cash per Note that is greater (A) than the Fundamental Change

(a) The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting

City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be purchased
at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds by the Trustee (or other Paying Agent appointed
by the Company), payment for Notes surrendered for repurchase (and not validly withdrawn prior to the close of business on the
Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change
Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in Section 15.02) and (ii)

promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental
Change Repurchase Price.

 

(b)              
If by 10:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed
by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be purchased on such Fundamental
Change Repurchase Date or any applicable extension thereof, then, with respect to Notes that have been properly surrendered for
repurchase and have not been validly withdrawn:

 

    91

     

    

 

(i)                
such Notes shall cease to be outstanding and interest shall cease to accrue on such Notes on such Fundamental Change Repurchase
Date or any applicable extension thereof (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

 

(ii)               
all other rights of the Holders of such Notes will terminate on the Fundamental Change Repurchase Date (other than (x)
the right to receive the Fundamental Change Repurchase Price and (y) if the Fundamental Change Repurchase Date falls after a Regular
Record Date but on or prior to the related Interest Payment Date, the right of the Holder on such Regular Record Date to receive
the accrued and unpaid interest to, but not including, the Fundamental Change Repurchase Date).

 

(c)              
Upon surrender of a Note that is to be repurchased in part pursuant to Section 15.02, the Company shall execute and the

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. To the extent that any securities
laws and regulations conflict with the provisions of this Indenture with respect to the repurchase of Notes, the Company shall

Redemption Only for Taxation Reasons

 

Section
16.01.    No Redemption Except for Taxation Reasons.
The Notes may be redeemed, in whole but not in part (a “Tax Redemption”), at the Company’s discretion
at the Redemption Price, if (w) on the next date on which any amount would be payable in respect of the Notes, the Company is
or would be required to pay Additional Amounts, (x) the Company cannot avoid any such payment obligation by taking reasonable
measures available (including, for the avoidance of doubt, appointment of a new Paying Agent but excluding reincorporation or
reorganization of the Company), and (y) the requirement arises as a result of:

 

    92

     

    

 

(a)              
any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the relevant Tax Jurisdiction
which change or amendment is announced and becomes effective after the date of the Offering Memorandum (or if the applicable Tax
Jurisdiction became a Tax Jurisdiction on a date after the date of the Offering Memorandum, after such later date); or

 

(b)              
any change in, or amendment to, the official application, administration or interpretation of such laws, regulations or
rulings (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published practice),
which change or amendment is announced and becomes effective after the date of the Offering Memorandum (or if the applicable Tax
Jurisdiction became a Tax Jurisdiction on a date after the date of the Offering Memorandum, after such later date) (each of the
foregoing clauses (a) and (b), a “Change in Tax Law”).

 

Section
16.02.    Notice of Tax Redemption.

 

(a)              
In the event that the Company exercises its Tax Redemption right pursuant to Section 16.01, it shall fix a date for redemption
(the “Tax Redemption Date”) and it or, at its written request received by the Trustee not less than five Business
Days prior to the date on which notice is sent to the Holders (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 cause to be mailed a notice (which notice shall be
irrevocable) of such Tax Redemption (a “Notice of Tax Redemption”) not less than 10 nor more than 60 days prior
to the Tax Redemption Date to each Holder of Notes so to be redeemed at its last address as the same appears on the Note Register;
provided, however, that if the Company shall give a Notice of Tax Redemption, it shall also give a written notice
of the Tax Redemption Date to the Trustee and the Paying Agent. The Tax Redemption Date must be a Business Day. The Company shall
not give any such notice of redemption earlier than 60 days prior to the earliest date on which the Company would be obligated
to make such payment of Additional Amounts if a payment in respect of the Notes was then due and at the time such notice is given,
the obligation to pay Additional Amounts must remain in effect. Simultaneously with providing a Notice of a Tax Redemption, the
Company will (i) issue a press release containing the relevant information or disclose the relevant information in a Current Report
on Form 8-K and (ii) post such information on its website. Prior to the mailing of any Notice of Tax Redemption of the Notes pursuant
to the foregoing, the Company shall deliver to the Trustee (i) an opinion of independent tax counsel of recognized standing qualified
under the laws of the relevant Tax Jurisdiction (which counsel shall be reasonably acceptable to the Trustee) to the effect that
there has been a Change in Tax Law which would entitle the Company to redeem the Notes hereunder. In addition, before the Company
mails a Notice of Tax Redemption, it shall deliver to the Trustee (i) an Officer’s Certificate to the effect that it cannot
avoid its obligation to pay Additional Amounts by the Company taking reasonable measures available to it. The Trustee shall accept
and shall be entitled to rely on such Officer’s Certificate and Opinion of Counsel as sufficient evidence of the existence
and satisfaction of the conditions as described above, in which event it will be conclusive and binding on all of the Holders.

 

    93

     

    

 

(b)              
Each Notice of Tax Redemption shall specify: the Tax Redemption Date;

 

(i)                
the Redemption Price;

 

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

 

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

 

(iv)             
that Holders may surrender their Notes called for redemption for conversion at any time from the date of the Notice of
Tax Redemption to the close of business on the second Scheduled Trading Day immediately preceding the Tax Redemption Date or,
if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption
Price;

 

(v)               
the procedures an exchanging Holder must follow to convert its Notes called for redemption and, if the Company chooses
to elect a Settlement Method for any such conversions, the relevant Settlement Method;

 

(vi)              
that Holders have the right to elect not to have their Notes redeemed by delivering to the Trustee written notice to that
effect not later than the 10th calendar day prior to the Tax Redemption Date;

 

(vii)             
that Holders who wish to elect not to have their Notes redeemed must satisfy the requirements set forth herein and in this
Indenture;

 

(viii)            
that, on and after the Tax Redemption Date, Holders who elect not to have their Notes redeemed will not receive any Additional
Amounts on any payments with respect to such Notes solely as a result of such Change in Tax Law (whether upon exchange, prepayment,
maturity or otherwise, and whether in cash, shares of Common Stock or otherwise), and all subsequent payments with respect to
the Notes will be subject to the deduction or withholding of such applicable Tax Jurisdiction taxes required by law to be deducted
or withheld as a result of such Change in Tax Law; and

 

(ix)              
the Conversion Rate and, if applicable, the number of shares of Common Stock added to the Conversion Rate in accordance
with Section 16.06.

 

A Notice of Tax Redemption shall be irrevocable.
In the case of a Tax Redemption, a Holder may convert any or all of its Notes called for redemption at any time from the date
of the Notice of Tax Redemption to the close of business on the second Scheduled Trading Day immediately preceding the Tax Redemption
Date or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the
Redemption Price.

Section
16.03.    Payment of Notes Called for Tax Redemption.

 

(a)              
If any Notice of Tax Redemption has been given in respect of the Notes in accordance with Section 16.02, the Notes shall
become due and payable on the Tax Redemption Date at the place or places stated in the Notice of Tax Redemption and at the applicable
Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Notice of Tax Redemption, the
Notes shall be paid and redeemed by the Company at the applicable Redemption Price.

 

Section
16.04.    Holders’ Right to Avoid Redemption.
Notwithstanding anything to the contrary in this Article 16, if the Company has given a Notice of Tax Redemption as described
in Section 16.02, each Holder of Notes shall have the right to elect that such Holder’s Notes will not be subject to the
Tax Redemption. If a Holder elects that its Notes shall not be subject to a Tax Redemption, the Company shall not be required
to pay Additional Amounts with respect to payments made in respect of such Notes following the Tax Redemption Date, and all subsequent
payments in respect of such Notes shall be subject to any Tax required to be withheld or deducted under the laws of an applicable
Tax Jurisdiction. The obligation to pay Additional Amounts to any electing Holder for payments made in periods prior to the Tax
Redemption Date shall remain subject to the exceptions set forth under Section 4.07. Holders must exercise their option to elect
to avoid a Tax Redemption by written notice (a “No Redemption Notice”) to the Trustee no later than the 10th
calendar day prior to the Tax Redemption Date; provided that a Holder that complies with the requirements for conversion of its
Notes as described in Article 14 before the close of business on the second Scheduled Trading Day immediately preceding the Tax
Redemption Date (or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides
for the Redemption Price) shall be deemed to have validly delivered a No Redemption Notice.

 

Section
16.05.    Restrictions on Tax 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 this Indenture, and such acceleration has not been rescinded, on or prior to the Tax Redemption Date (or, if the
Company fails to pay the Redemption Price, such later date on which the Company pays the Redemption Price) (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).

 

Section
16.06.    Mutatis Mutandis.
The above provisions will apply, mutatis mutandis, to any successor of the Company with respect to a Change in Tax Law occurring
after the time such Person becomes successor to the Company.

 

Section
16.07.    No Sinking Fund.

hereunder, including under Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section 10.04 and Section 15.04 as fully to
all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those Sections
to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating
agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes
for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person eligible to serve
as trustee hereunder pursuant to Section 7.08.

of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor corporation or
other entity.

 

Any authenticating agent may at any time
resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency

such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible
under this Section, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice
of such appointment to the Company and shall mail notice of such appointment to all Holders as the names and addresses of such
Holders appear on the Note Register.

 

The Company agrees to pay to the authenticating
agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent,
if it determines such agent’s fees to be unreasonable.

Section
17.14.    Waiver of Jury Trial; Submission to Jurisdiction.

action, or proceeding that may be brought in connection with this Indenture or the Notes, including such actions, suits or proceedings

(the “Authorized Agent”), upon whom process may be served in any suit, action or proceeding arising out of
or based upon this Indenture or the Notes or the transactions contemplated herein which may be instituted in any state or Federal
court in the City of New York, by any Holder or the Trustee, and expressly accepts the non-exclusive jurisdiction of any such
court in respect of any such suit, action or proceeding. The Company’s General Counsel has hereby accepted such appointment
and has agreed to act as said agent for service of process, and the Company agrees to take any and all action, including the filing
of any and all documents that may be necessary to continue such respective appointment in full force and effect as aforesaid.
Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company.
Notwithstanding the foregoing, any action involving the Company arising out of or based upon this Indenture or the Notes may be
instituted by any Holder or the Trustee in any other court of competent jurisdiction. The Company expressly consents to the jurisdiction
of any such court in respect of any such action and waives any other requirements of or objections to personal jurisdiction with
respect thereto.

OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

Section
17.16.  Calculations. Except
as otherwise provided herein, the Company shall be responsible for making all calculations called for under the Notes or this
Indenture. These calculations include, but are not limited to, determinations of the Stock Price or Trading Price, the Last Reported
Sale Prices per share of the Common Stock, the Redemption Price, the Fundamental Change Repurchase Price, the Conversion Price,

to each of the Trustee and the Conversion Agent (if other than the Trustee), and each of the Trustee and Conversion Agent is entitled
to rely conclusively upon the accuracy of such calculations without independent verification. The Trustee will forward the Company’s

event shall the Trustee or the Conversion Agent be charged with knowledge of or have any duty to monitor Stock Price or Observation
Period. Neither the Trustee nor the Conversion Agent shall have any responsibility for calculations or determinations of amounts,
determining whether events requiring or permitting conversion have occurred, determining whether any adjustment is required to
be made with respect to conversion rights and, if so, how much, or for the delivery of shares of Common Stock.

In order to comply with laws, rules, regulations
and executive orders in effect from time to time applicable to banking institutions, including those relating to the funding of
terrorist activities and money laundering (“Applicable AML Laws”), the Trustee is required to obtain verify
and record certain information relating to individuals and entities which maintain a business relationship with the Trustee. Accordingly,
the Company agrees to provide to the Trustee upon its request from time to time such identifying information and documentation
as may be available for the Company in order to enable the Trustee to comply with Applicable AML Laws.

 

Section
17.18.  FATCA. In order to
enable the Company and the Trustee to comply with its obligation with respect to this Indenture and the Notes under FATCA (inclusive
of official interpretations of FATCA promulgated by competent authorities), any applicable agreement entered into pursuant to
Section 1471(b) of the Code and/or any applicable intergovernmental agreement entered into in order to implement FATCA, each of
the Company and the Trustee each agree (i) to provide to one another such reasonable information that is within its possession
and is reasonably requested by the other to assist the other in determining whether it has tax related obligations under FATCA,
and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under this Indenture to the extent
necessary to comply with FATCA. The terms of this section shall survive the termination of this Indenture.

[FORM OF REVERSE OF NOTE]

 

ROYAL CARIBBEAN CRUISES LTD.

4.250% Convertible Senior Note due 2023

 

This Note is one of
a duly authorized issue of Notes of the Company, designated as its 4.250% Convertible Senior Notes due 2023 (the “Notes”),
issued under and pursuant to an Indenture, dated as of June 9, 2020 (the “Indenture”), between the Company and
The Bank of New York Mellon Trust Company, N.A., as trustee (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. The Notes represent the aggregate principal amount of outstanding
Notes from time to time endorsed hereon and the aggregate principal amount of outstanding Notes represented hereby may from time
to time be increased or reduced to reflect purchases, cancellations, conversions or transfers permitted by the Indenture.

 

In case an Event of
Default relating to a bankruptcy (or similar proceeding) with respect to the Company or any of the Company’s Significant
Subsidiaries or any group of the Company’s Subsidiaries that, taken together, would constitute a Significant Subsidiary shall
have occurred, the principal of, and interest on, all Notes shall automatically become immediately due and payable, in the manner
and with the effect set forth in the Indenture. In case any other Event 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 30% 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 Redemption Price on the Tax
Redemption Date and 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. Upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be,
cash, shares of Common Stock or a combination of cash and shares of Common Stock.

 

Subject to the terms
and conditions of the Indenture, Additional Amounts will be paid in connection with any payments made and deliveries caused to
be made by the Company or any successor under or with respect to the Indenture and the Notes, including, but not limited to, payments
of principal (including, if applicable, the Redemption Price and the Fundamental Change Prepayment Price), payments of interest
and payments of cash and/or deliveries of Common Stock (together with payments of cash in lieu of fractional Common Stock) upon
exchange, to ensure that the net amount received by the beneficial owner after such withholding or deduction (and after deducting
any taxes on the Additional Amounts) will equal the amount that would have been received by such beneficial owner had no such withholding
or deduction been required.

 

    Exhibit A-6

     

    

 

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

 

No reference herein
to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Redemption Price and 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 minimum denominations of $1,000 principal amount and integral multiples of $1,000 in excess
thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations
provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations,
without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any
transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued
upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

 

The Notes are not subject
to redemption through the operation of any sinking fund or otherwise. Under certain circumstances specified in the Indenture, the
Notes will be subject to redemption by the Company at the Redemption Price.

 

Upon the occurrence
of a Fundamental Change, the Holder has the right, at such Holder’s option exercised in the manner specified in the Indenture,
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 of $1,000 in excess 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 second Scheduled Trading Day immediately preceding the Maturity
Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof, into cash, shares
of Common Stock or a combination of each and shares of Common Stock, at the Company’s election, at the Conversion Rate specified
in the Indenture, as adjusted from time to time as provided in the Indenture.

FIVE STAR SENIOR LIVING INC.

 

AMENDED AND RESTATED 2014 EQUITY COMPENSATION
PLAN

 

EFFECTIVE JUNE 9, 2020

 

 

		1.	PURPOSE

 

The purpose of this Amended and Restated 2014 Equity Compensation
Plan (the "Plan") is to encourage employees, officers, directors and other individuals (whether or not employees) who
render services to Five Star Senior Living Inc. (the "Company") and its Subsidiaries (as hereinafter defined), to continue
their association with the Company and its Subsidiaries by providing opportunities for them to participate in the ownership of
the Company and in its future growth through the granting of options to acquire the Company's stock ("Options"), stock
awards, including stock to be transferred subject to restrictions ("Stock Awards") and other rights, including Stock
Appreciation Rights (as defined in Section 6), to receive compensation in amounts determined by the value of the Company's stock
("Other Rights"). The term "Subsidiary" as used in the Plan means a corporation or other business entity of
which the Company owns, directly or indirectly through an unbroken chain of ownership, fifty percent or more of the total combined
voting power of all classes of stock, in the case of a corporation, or fifty percent or more of the total combined interests by
value, in the case of any other type of business entity.

 

		2.	ADMINISTRATION OF THE PLAN

 

The Plan shall be administered by the Compensation Committee
of the Company's Board of Directors (the "Board") or by the Board itself. The Compensation Committee shall from time
to time determine to whom awards shall be granted under the Plan, whether Options granted shall be incentive stock options ("ISOs")
or nonqualified stock options ("NSOs"), the terms of the Options (including vesting provisions) and the number of shares
of Common Stock (as hereinafter defined) that may be granted under Options, and the number of shares subject to (and other terms
of) Stock Awards or Other Rights. The Compensation Committee shall report to the Board the names of individuals to whom Options,
Stock Awards or Other Rights are to be granted, the number of shares covered and the terms and conditions of each grant. The determinations
and actions described in this Section 2 and elsewhere in the Plan may be made by the Compensation Committee or by the Board, as
the Board shall direct in its discretion, and references in the Plan to the Compensation Committee shall be understood to refer
to the Board in any such case. The Compensation Committee shall have the authority to adopt, amend and rescind such rules and regulations
as, in its opinion, may be advisable in the administration of the Plan. All questions of interpretation and application of such
rules and regulations of the Plan and of awards granted hereunder shall be subject to the determination of the Compensation Committee
in its discretion, which determination shall be final and binding. The Plan is intended to be administered in such a manner as
to permit those Options granted hereunder and specially designated under Section 5 hereof as an ISO to qualify as incentive stock
options as described in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), and shall be construed
in a manner consistent with that interpretation. For so long as Section 16 of the Securities Exchange Act of 1934, as amended from
time to time (the "Exchange Act"), is applicable to the Company, each member of the Committee shall be a "non-employee
director" or the equivalent within the meaning of Rule 16b-3 under the Exchange Act, and shall meet such other requirements
as the Board may determine to be necessary or appropriate.

 

With respect to persons subject to Section 16 of the Exchange
Act ("Insiders"), transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3 or
its successor under the Exchange Act. To the extent any provision of the Plan or action by the Committee fails to so comply, it
shall be deemed to be modified so as to be in compliance with such Rule, or, if such modification is not possible, it shall be
deemed to be null and void, to the extent permitted by law and deemed advisable by the Committee.

 

    	 	 	 

     

    

 

		3.	STOCK SUBJECT TO THE PLAN

 

The total number of shares of capital stock of the Company that
may be subject to Options, Stock Awards and Other Rights under the Plan shall be 2,907,259 shares of the Company's common stock,
par value $0.01 per share (the "Common Stock"), inclusive of shares of Common Stock subject to awards outstanding on
the Restatement Effective Date (as defined below). All of shares of capital stock of the Company available under the Plan may be
granted as ISOs. Shares issued under the Plan may be from authorized but unissued shares of Common Stock. The maximum number of
shares of Common Stock subject to ISOs that may be granted to any Optionee in the aggregate in any calendar year shall not exceed
100,000 shares. The limits set forth in this Section 3 shall be subject to adjustment in accordance with the provisions of Section
10. Awards (including those issued under the Plan prior to the Restatement Effective Date) that fail to vest or, if applicable,
are not fully exercised prior to the award's expiration or termination shall again become available for grant under the terms of
the Plan.

 

		4.	ELIGIBILITY

 

The individuals who shall be eligible to receive Option grants,
Stock Awards and Other Rights under the Plan shall be employees, officers, directors and other individuals who render services
to the management, operation or development of the Company or a Subsidiary and who have contributed or may be expected to contribute
to the success of the Company or a Subsidiary. ISOs shall not be granted to any individual who is not (i) an employee of the Company
or (ii) an employee of a Subsidiary who is treated as an employee of the Company for purposes of Section 422 of the Code. The term
 "Optionee," as used in the Plan, refers to any individual to whom an Option has been granted.

 

		5.	TERMS AND CONDITIONS OF OPTIONS

 

Every Option shall be evidenced by a written Stock Option Agreement
in such form as the Compensation Committee shall approve from time to time, specifying the number of shares of Common Stock that
may be purchased pursuant to the Option, the time or times at which the Option shall become exercisable in whole or in part, whether
the Option is intended to be an ISO or an NSO and such other terms and conditions as the Compensation Committee shall approve,
and containing or incorporating by reference the following terms and conditions.

 

		(a)	Duration. Each Option shall expire not later than ten years from its date of grant; provided, however, that no
ISO granted to an employee who owns (directly or under the attribution rules of Section 424(d) of the Code) stock possessing more
than ten percent of the total combined voting power of all classes of stock of the Company or any Subsidiary shall expire later
than five years from its date of grant.

 

		(b)	Exercise Price. The exercise price per share for each Option shall be at least 100 percent of the Fair Market
Value (as hereinafter defined) of the shares on the date on which the Compensation Committee awards the Option, which shall be
considered the date of grant of the Option for purposes of fixing the price; and provided, further, that the price with respect
to an ISO granted to an employee who at the time of grant owns (directly or under the attribution rules of Section 424(d) of the
Code) stock representing more than ten percent of the voting power of all classes of stock of the Company or of any Subsidiary
shall be at least 110 percent of the Fair Market Value of the shares on the date of grant of the ISO. For purposes of the Plan,
the "Fair Market Value" of a share of Common Stock at any particular date shall be determined according to the following
rules: (i) if the Common Stock is not at the time listed or admitted to trading on a stock exchange or the NASDAQ, the Fair Market
Value shall be the closing price of the Common Stock on the date in question in the over-the-counter market, as such price is reported
in a publication of general circulation selected by the Board and regularly reporting the price of the Common Stock in such market,
including any market that is outside of the United States; provided, however, that if the price of the Common Stock is not so reported,
the Fair Market Value shall be determined in good faith by the Board, which may take into consideration (1) the price paid for
the Common Stock in the most recent trade of a substantial number of shares known to the Board to have occurred at arm's length
between willing and knowledgeable investors, (2) an appraisal by an independent party or (3) any other method of valuation undertaken
in good faith by the Board, or some or all of the above as the Board shall in its discretion elect; or (ii) if the Common Stock
is at the time listed or admitted to trading on any stock exchange, including any market that is outside of the United States,
or the NASDAQ, then the Fair Market Value shall be the closing sale price of the Common Stock on the date in question on the principal
exchange or the NASDAQ, as the case may be, on which the Common Stock is then listed or admitted to trading. If no reported sale
of Common Stock takes place on the date in question on the principal exchange or the NASDAQ, as the case may be, then the most
recent previous reported closing sale price of the Common Stock (or, in the Board's discretion, the reported closing asked price)
of the Common Stock on such date on the principal exchange or the NASDAQ, as the case may be, shall be determinative of Fair Market
Value. Without limitation of the authority of the Compensation Committee under Section 10 hereof, unless approved by the Company's
stockholders, no Option shall be settled, canceled, forfeited, exchanged or surrendered in exchange or otherwise in consideration
for either (A) a new Option or SAR (as defined below) with an exercise price that is less than that of such settled, canceled,
forfeited, exchanged or surrendered Option (B) a Stock Award or Other Right with an intrinsic value at issuance in an amount greater
than the excess of the Fair Market Value of the Common Stock over the exercise price per share applicable to the Option or (C)
in exchange for a payment in cash in an amount greater than the excess of the Fair Market Value of the Common Stock over the exercise
price per share applicable to the Option.

 

 

    	 	2	 

     

    

 

		(c)	Method of Exercise. To the extent that it has become exercisable under the terms of the Stock Option Agreement,
an Option may be exercised from time to time by notice acceptable to the Chief Executive Officer of the Company, or his delegate,
stating the number of shares with respect to which the Option is being exercised and accompanied by payment of the exercise price
(and any applicable withholding tax) in cash or check payable to the Company or, if the Stock Option Agreement so provides, other
payment or deemed payment described in this Section 5(c). Such notice shall be delivered in person to the Chief Executive Officer
of the Company, or his delegate, or shall be sent by registered mail, return receipt requested, to the Chief Executive Officer
of the Company, or his delegate, in which case delivery shall be deemed made on the date such notice is deposited in the mail.

 

Alternatively, payment of the exercise price
may be made:

 

		(i)	In whole or in part in shares of Common Stock already owned by the Optionee or to be received upon exercise of the Option;
provided, however, that such shares are fully vested and free of all liens, claims and encumbrances of any kind; and provided,
further, that the Optionee may not make payment in shares of Common Stock that he acquired upon the earlier exercise of any ISO
(or other "incentive stock option"), unless he has held the shares for at least two years after the date the ISO was
granted and at least one year after the date the ISO was exercised. If payment is made in whole or in part in shares of Common
Stock, then, in the case of certificated shares, the Optionee shall deliver to the Company stock certificates registered in his
name representing a number of shares of Common Stock legally and beneficially owned by him, fully vested and free of all liens,
claims and encumbrances of every kind and having a Fair Market Value on the date of delivery that is not greater than the exercise
price, such stock certificates to be duly endorsed, or accompanied by stock powers duly endorsed, by the record holder of the shares
represented by such stock certificates. The Compensation Committee may approve comparable procedures to those set forth in the
preceding sentence in the event of shares held in book-entry form. If the exercise price exceeds the Fair Market Value of the shares
for which stock certificates are delivered, the Optionee shall also deliver cash or a check payable to the order of the Company
in an amount equal to the amount of that excess or, if the Stock Option Agreement so provides, his promissory note as described
in paragraph (2) of this Section 5(c); or

  

		(ii)	To the extent permitted under applicable law, by payment in cash of the par value of the Common Stock to be acquired and by
payment of the balance of the exercise price in whole or in part by delivery of the Optionee's recourse promissory note, in a form
specified by the Company, secured by the Common Stock acquired upon exercise of the Option and such other security as the Compensation
Committee may require.

 

In the case of an exercise pursuant to clause (1)
or (2) above, the Company may require the Optionee to pay to the Company in cash or by check, the amount of any withholding tax
due in connection with the exercise. At the time specified in an Optionee's notice of exercise, the Company shall, without issue
or transfer tax to the Optionee, in the discretion of the Company, either (A) register the Optionee's ownership of such shares
in book-entry form or (B) deliver to him at the main office of the Company, or such other place as shall be mutually acceptable,
a stock certificate for the shares as to which his Option is exercised. If the Optionee fails to pay for or to accept delivery
of all or any part of the number of shares specified in his notice upon tender of delivery thereof, his right to exercise the Option
with respect to those shares shall be terminated, unless the Company otherwise agrees.

 

		(d)	Exercisability. An Option may be exercised so long as it is outstanding from time to time in whole or in part,
to the extent and subject to the terms and conditions that the Compensation Committee in its discretion may provide in the Stock
Option Agreement. Such terms and conditions shall include provisions for exercise within twelve (12) months after his or her death
or disability (within the meaning of Section 22(e)(3)) of the Code, provided that no Option shall be exercisable after the expiration
of the maximum term of the Option. Except as the Compensation Committee in its discretion may otherwise provide in the Stock Option
Agreement, an Option shall cease to be exercisable upon the expiration of ninety (90) days following the termination of the Optionee's
employment with, or his other provision of services to, the Company or a subsidiary, subject to the expiration of the maximum term
of the Option and Section 10 hereof.

 

 

    	 	3	 

     

    

 

		(e)	Notice of ISO Stock Disposition. The Optionee must notify the Company promptly in the event that he sells, transfers,
exchanges or otherwise disposes of any shares of Common Stock issued upon exercise of an ISO before the later of (i) the second
anniversary of the date of grant of the ISO and (ii) the first anniversary of the date the shares were issued upon his exercise
of the ISO.

 

		(f)	No Rights as Stockholder. An Optionee shall have no rights as a stockholder with respect to any shares covered
by an Option until the date of either registration of the Optionee's ownership of such shares in book-entry form or the issuance
of a stock certificate to him for the shares. No adjustment shall be made for dividends or other rights for which the record date
is earlier than the date the stock certificate is issued (or ownership is registered by book-entry), other than as required or
permitted pursuant to Section 10.

 

		(g)	Transferability of Options. Options shall not be transferable by the Optionee otherwise than by will or under
the laws of descent and distribution, and shall be exercisable during his or her lifetime only by the Optionee, except that the
Compensation Committee may specify in a Stock Option Agreement that pertains to an NSO that the Optionee may transfer such NSO
to a member of the Immediate Family of the Optionee, to a trust solely for the benefit of the Optionee and the Optionee's Immediate
Family, or to a partnership or limited liability company whose only partners or members are the Optionee and members of the Optionee's
Immediate Family. "Immediate Family" shall mean, with respect to any Optionee, such Optionee's child, stepchild, grandchild,
parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or
sister-in-law, and shall include adoptive relationships.

 

		6.	STOCK APPRECIATION RIGHTS

 

The Committee may grant Stock Appreciation Rights ("SARs")
in respect of such number of Common Stock subject to the Plan as it shall determine, in its discretion, and may grant SARs either
separately or in connection with Options, as described in the following sentence. An SAR granted in connection with an Option may
be exercised only to the extent of the surrender of the related Option, and to the extent of the exercise of the related Option
the SAR shall terminate. Common Stock covered by an Option that terminates upon the exercise of a related SAR shall cease to be
available under the Plan. The terms and conditions of an SAR related to an Option shall be contained in the Stock Option Agreement,
and the terms of an SAR not related to any Option shall be contained in an SAR Agreement. The base value per share for share subject
to an SAR shall be at least 100 percent of the Fair Market Value of the shares on the date on which the Compensation Committee
awards the SAR. Without limitation of the authority of the Compensation Committee under Section 10 hereof, unless approved by the
Company's stockholders, no SAR shall be settled, canceled, forfeited, exchanged or surrendered in exchange or otherwise in consideration
for (A) a new SAR or Option with a base value per share or exercise price that is less than that of such settled, canceled, forfeited,
exchanged or surrendered SAR, (B) a Stock Award or Other Right with an intrinsic value at issuance in an amount greater than the
excess of the Fair Market Value of the Common Stock over the exercise price per share applicable to the Option or (C) in exchange
for a payment in cash in an amount greater than the excess of the Fair Market Value of the Common Stock over the base value per
share applicable to the SAR. Upon exercise of an SAR, the Optionee shall be entitled to receive from the Company an amount equal
to the excess of the Fair Market Value, on the exercise date, of the number of shares of Common Stock as to which the SAR is exercised,
over the exercise price for those shares under a related Option or, if there is no related Option, over the base value stated in
the SAR Agreement. Any amount payable by the Company upon exercise of an SAR shall be paid in the form of cash or other property
(including Common Stock), as provided in the Stock Option Agreement or SAR Agreement governing the SAR.

 

		7.	STOCK AWARDS

 

The Compensation Committee may grant or award Stock Awards in
respect of such number of shares of Common Stock, and subject to such terms or conditions (if any), as it shall determine and specify
in a Stock Award Agreement, and may award shares of Common Stock which are not subject to vesting or forfeiture conditions. The
Compensation Committee may provide in a Stock Option Agreement for an Option to be exercisable for Common Stock subject to forfeiture
conditions and restrictions on transfer ("Restricted Stock").

 

    	 	4	 

     

    

 

A holder of Restricted Stock shall have all of the rights of
a stockholder of the Company, including the right to vote the shares and the right to receive any cash dividends, unless the Compensation
Committee shall otherwise determine. Unless a grantee's Restricted Stock Agreement provides to the contrary, unvested shares of
Restricted Stock granted under the Plan shall not be transferred without the written consent of the Compensation Committee. In
addition, at the time of termination for any reason of a grantee's employment or other service relationship with the Company or
a Subsidiary, the Company shall have the right, in the case of unvested Restricted Stock, (1) to cause the forfeiture of such shares
of Restricted Stock for no consideration (2) to purchase all or any of such shares of Restricted Stock at a price equal to the
lower of (a) the price paid to the Company for such shares of Restricted Stock or (b) the Fair Market Value of such shares of Restricted
Stock at the time of repurchase, (3) to waive vesting requirements, (4) to permit continued vesting based on such criteria as the
Compensation Committee shall determine or (5) to provide for such other treatment as the Compensation Committee shall determine
and set forth in the applicable agreement.. Nothing in the Plan shall be construed to give any person the right to require the
Company to purchase any Common Stock granted as Restricted Stock.

 

Certificates representing Restricted Stock shall be imprinted
with a legend to the effect that the shares represented may not be sold, exchanged, transferred, pledged, hypothecated or otherwise
disposed of except in accordance with the terms of the Restricted Stock Agreement. If shares of Restricted Stock are held in book
entry form, statements evidencing those shares shall include a similar legend. If the Compensation Committee so determines, the
holder of Restricted Stock may be required to deposit certificates representing the Restricted Stock with the President, Treasurer,
Secretary or other officer of the Company or with an escrow agent designated by the Compensation Committee, together with a stock
power or other instrument of transfer appropriately endorsed in blank.

 

		8.	METHOD OF GRANTING OPTIONS, STOCK AWARDS AND OTHER RIGHTS

 

The grant of Options, Stock Awards and Other Rights shall be
made by action of the Compensation Committee; provided, however, that if an individual to whom a grant has been made fails to execute
and deliver to the Compensation Committee a Stock Option Agreement, Stock Award Agreement or agreement with respect to an Other
Award within thirty days after it is submitted to him, the Option, Stock Award or Other Award granted under the agreement shall
be voidable by the Company at its election, without further notice to the grantee.

 

		9.	REQUIREMENTS OF LAW

 

The Company shall not be required to transfer Common Stock or
to sell or issue any shares upon the exercise of any Option or SAR or Other Award if the issuance of such shares will result in
a violation by the recipient or the Company of any provisions of any law, statute or regulation of any governmental authority.
Specifically, in connection with the Securities Act of 1933, as amended from time to time (the "Securities Act"), the
Company shall not be required to issue shares unless the Compensation Committee has received evidence satisfactory to it to the
effect that the holder of the Restricted Stock or the Option or SAR or Other Award will not transfer such shares except pursuant
to a registration statement in effect under the Securities Act or unless an opinion of counsel satisfactory to the Company has
been received by the Company to the effect that registration is not required. Any determination in this connection by the Compensation
Committee shall be conclusive. The Company shall not be obligated to take any other affirmative action in order to cause the transfer
of Common Stock to comply with any law or regulations of any governmental authority, including, without limitation, the Securities
Act or applicable state securities laws.

 

		10.	CHANGES IN CAPITAL STRUCTURE

 

In the event that the outstanding shares of Common Stock are
hereafter changed for a different number or kind of shares or other securities of the Company, by reason of a reorganization, recapitalization,
exchange of shares, stock split, combination of shares or dividend payable in shares or other securities or in the event of a similar
corporate event, a corresponding adjustment shall be made by the Compensation Committee in the number and kind of shares or other
securities covered by outstanding Options, Stock Awards and Other Rights and for which Options, Stock Awards and Other Rights may
be granted under the Plan. Any such adjustment in outstanding Options shall be made without change in the total price applicable
to the unexercised portion of the Option, but the price per share specified in each Stock Option Agreement shall be correspondingly
adjusted; provided, however, that no adjustment shall be made with respect to an ISO that would constitute a modification as defined
in Section 424 of the Code without the consent of the holder. Any such adjustment made by the Compensation Committee shall be conclusive
and binding upon all affected persons, including the Company and all award recipients.

 

If while unexercised Options remain outstanding under the Plan
the Company merges or consolidates with a wholly-owned subsidiary for the purpose of reincorporating itself under the laws of another
jurisdiction, the Optionees will be entitled to acquire shares of common stock of the reincorporated Company upon the same terms
and conditions as were in effect immediately prior to such reincorporation (unless such reincorporation involves a change in the
number of shares or the capitalization of the Company, in which case proportional adjustments shall be made as provided above)
and the Plan, unless otherwise rescinded by the Board, will remain the Plan of the reincorporated Company.

 

    	 	5	 

     

    

 

Except as otherwise provided in the preceding paragraph, if
the Company or a subsidiary is merged or consolidated with another corporation, whether or not the Company is the surviving entity,
or if the Company is liquidated or sells or otherwise disposes of all or substantially all of its assets to another entity while
unexercised awards remain outstanding under the Plan, or if other circumstances occur in which the Compensation Committee in its
sole and absolute discretion deems it appropriate for the provisions of this paragraph to apply (in each case, an "Applicable
Event"), then: (a) in the discretion of the Compensation Committee, each holder of an outstanding award under the plan shall
be entitled, upon exercise or vesting of the award (as applicable), to receive in lieu of shares of Common Stock, such stock or
other securities or property as he or she would have received had he exercised or vesting in the award immediately prior to the
Applicable Event; or (b) the Compensation Committee may, in its sole and absolute discretion, cancel all outstanding and unexercised
awards as of the effective date of any such Applicable Event; or (c) the Compensation Committee may, in its sole discretion, convert
some or all awards under the Plan into awards to purchase (or with respect to) the stock or other securities of the surviving corporation
pursuant to an Applicable Event; or (d) the Compensation Committee may, in its sole and absolute discretion, cause the outstanding
and unexercised awards to be cancelled in exchange for a payment in cash equal to the value (if any) of the shares subject to such
award (less any applicable exercise or base price), pursuant to an Applicable Event; provided, however, that notice of any cancellation
pursuant to clause (b) above shall be given to each holder of an Option or SAR not less than thirty days preceding the effective
date of such Applicable Event. The Compensation Committee may, in its sole discretion, provide for a combination of the foregoing
treatments and/or for different treatment hereunder of different awards and there is no requirement for all awards of the same
type to receive the same treatment hereunder. Notwithstanding the foregoing, immediately upon the occurrence of a "Change
in Control" or "Termination Event" (as each is defined on Exhibit A hereto) all awards issued and outstanding under
the Plan shall become fully vested and exercisable (as the case may be), whether or not the holder of the award experiences a termination
of employment or service in connection with the Change in Control.

 

Except as expressly provided to the contrary in this Section
10 or as otherwise determined by the Compensation Committee, the issuance by the Company of shares of stock of any class for cash
or property or for services, either upon direct sale, upon the exercise of rights or warrants, upon conversion of shares or obligations
of the Company convertible into such shares or other securities or otherwise, shall not affect the number, class or price of shares
of Common Stock then subject to outstanding Options, Stock Awards or Other Rights.

 

		11.	FORFEITURE FOR DISHONESTY, VIOLATION OF AGREEMENTS OR TERMINATION FOR CAUSE

 

Notwithstanding any provision of the Plan to the contrary, if
the Compensation Committee determines, after full consideration of the facts, that:

 

		(a)	the Optionee (or holder of a Stock Award or Other Right) has been engaged in fraud, embezzlement or theft in the course of
his or her employment by or involvement with the Company or a Subsidiary, has made unauthorized disclosure of trade secrets or
other proprietary information of the Company or a Subsidiary or of a third party who has entrusted such information to the Company
or a Subsidiary, or has been convicted of a felony, or crime involving moral turpitude or any other crime which reflects negatively
upon the Company; or

 

		(b)	the Optionee (or holder of a Stock Award or Other Right) has violated the terms of any employment, noncompetition, nonsolicitation,
confidentiality, nondisclosure or other similar agreement with the Company to which he is a party; or

 

		(c)	the employment or involvement with the Company or a Subsidiary of the Optionee (or holder of a Stock Award or Other Right)
was terminated for "cause," as defined in any employment agreement with the Optionee (or holder of a Stock Award or Other
Right), if applicable, or if there is no such agreement, as determined by the Compensation Committee, which may determine that
 "cause" includes among other matters the willful failure or refusal of the Optionee (or holder of a Stock Award or Other
Right) to perform and carry out his or her assigned duties and responsibilities diligently and in a manner satisfactory to the
Compensation Committee;

 

then the recipient's right to exercise an Option or SAR shall
terminate as of the date of such act (in the case of (a) or (b)) or such termination (in the case of (c)), the recipient shall
forfeit all unexercised Options and SARS (or the holder shall forfeit all Other Rights) and the Company shall have the right to
repurchase all or any part of the shares of Common Stock acquired by the recipient upon any previous exercise of any Option or
SAR (or any previous acquisition by the holder of a Stock Award, whether then vested or unvested), at a price equal to the lower
of (a) the amount paid to the Company upon such exercise or acquisition, or (b) the Fair Market Value of such shares at the time
of repurchase. If an Optionee or holder of a SAR whose behavior the Company asserts falls within the provisions of the clauses
above has exercised or attempts to exercise an Option or SAR prior to consideration of the application of this Section 11 or prior
to a decision of the Compensation Committee, the Company shall not be required to recognize such exercise until the Compensation
Committee has made its decision and, in the event any exercise shall have taken place, it shall be of no force and effect (and
shall be void ab initio) if the Compensation Committee makes an adverse determination; provided, however, that if the Compensation
Committee finds in favor of the recipient then the recipient will be deemed to have exercised the Option or SAR as of the date
he or she originally gave notice of his or her attempt to exercise or actual exercise, as the case may be. The decision of the
Compensation Committee as to the cause of an Optionee's (or holder of a Stock Award or Other Right) discharge and the damage done
to the Company shall be final, binding and conclusive. No decision of the Compensation Committee, however, shall affect in any
manner the finality of the discharge of such Optionee (or holder of a Stock Award or Other Right) by the Company. For purposes
of this Section 11, reference to the Company shall include any Subsidiary. Notwithstanding anything herein to the contrary, the
Compensation Committee may provide, either in an award agreement or separately, that the provisions of this Section 11 shall not
apply following a change in control of the Company (as defined by the Compensation Committee).

 

    	 	6	 

     

    

 

		12.	MISCELLANEOUS

 

		(a)	No Guarantee of Employment or Other Service Relationship. Neither the Plan nor any Stock Option Agreement, Stock
Award Agreement or agreement with respect to an Other Award shall give an employee the right to continue in the employment of the
Company or a Subsidiary or give the Company or a Subsidiary the right to require an employee to continue in employment.

 

Neither the Plan nor any Stock Option Agreement, Stock
Award Agreement or agreement with respect to an Other Award shall give a director or other service provider the right to continue
to perform services for the Company or a Subsidiary or give the Company or a Subsidiary the right to require the director or service
provider to continue to perform services.

 

		(b)	Tax Withholding. To the extent required by law, the Company shall withhold or cause to be withheld income and
other taxes with respect to any income recognized by a recipient by reason of the exercise or vesting of an Option or Stock Award,
or payments with respect to Other Rights, and as a condition to the receipt of any Option, Stock Award or Other Right the Optionee
shall agree that if the amount payable to him by the Company and any Subsidiary in the ordinary course is insufficient to pay such
taxes, then he shall upon the request of the Company pay to the Company an amount sufficient to satisfy its tax withholding obligations.

 

Without limiting the foregoing, the Compensation Committee
may in its discretion permit any Optionee's (or holder of a Stock Award or Other Right) withholding obligation to be paid in whole
or in part in the form of shares of Common Stock by withholding from the shares to be issued or by accepting delivery from the
Optionee (or holder of a Stock Award or Other Right) of shares already owned by him. The Fair Market Value of the shares for such
purposes shall be determined as set forth in Section 5(b). An Optionee (or holder of a Stock Award or Other Right) may not make
any such payment in the form of shares of Common Stock acquired upon the exercise of an ISO until the shares have been held by
him for at least two years after the date the ISO was granted and at least one year after the date the ISO was exercised. If payment
of withholding taxes is made in whole or in part in shares of Common Stock, the Optionee (or holder of a Stock Award or Other Right)
shall deliver to the Company stock certificates registered in his name representing shares of Common Stock legally and beneficially
owned by him, fully vested and free of all liens, claims and encumbrances of every kind, duly endorsed or accompanied by stock
powers duly endorsed by the record holder of the shares represented by such stock certificates. The Compensation Committee may
approve comparable procedures to those set forth in the preceding sentence in the event of shares held in book-entry form. If the
Optionee (or holder of a Stock Award or Other Right) is subject to Section 16(a) of the Exchange Act, his ability to pay his withholding
obligation in the form of shares of Common Stock shall be subject to such additional restrictions as may be necessary to avoid
any transaction that might give rise to liability under Section 16(b) of the Exchange Act.

 

		(c)	Use of Proceeds. The proceeds from the issuance of shares pursuant to the exercise of Options shall constitute
general funds of the Company.

 

		(d)	Certain Vesting Rules. Notwithstanding anything in the Plan to the contrary, the Compensation Committee shall have the
authority to (1) grant awards hereunder to members of the Board that are, to the extent determined by the Compensation Committee,
vested upon grant and (2) accelerate awards upon a termination of a participant’s employment or service (which the Compensation
Committee may do in its discretion); any such acceleration provisions may be (but are not required to be) set forth in an award
agreement (which may, without limitation, provide for accelerated vesting upon the death of a participant or upon a change in control
or similar event).

		(e)	Construction. All masculine pronouns used in this Plan shall include both sexes; the singular shall include the
plural and the plural the singular unless the context otherwise requires. The titles of the sections of the Plan are included for
convenience only and shall not be construed as modifying or affecting their provisions. Any reference herein to a statutory or
regulatory provision includes the provision as amended, supplemented, or replaced.

 

		(f)	Governing Law. This Plan shall be governed by and construed in accordance with the laws of the State of Maryland,
without regard to the principles of conflict of laws.

 

		13.	EFFECTIVE DATE, DURATION, AMENDMENT AND TERMINATION OF PLAN

 

The Plan was originally effective as of the date of the Company's
2014 Annual Meeting of Stockholders, and this amendment and restatement shall be effective as of the date of the Company's 2020
Annual Meeting of Stockholders (the "Restatement Effective Date") subject to approval by the holders of a majority of
the outstanding shares of capital stock present, or represented, and entitled to vote thereon (voting as a single class) at a duly
held meeting of the stockholders of the Company. Awards of Options, Other Rights or Stock Awards that are conditioned upon the
approval of the Plan by the stockholders may be granted prior to approval. The Compensation Committee may grant Options, Stock
Awards or Other Rights under the Plan from time to time until the close of business on June 9, 2030. The Board may at any time
amend the Plan; provided, however, that without approval of the Company's stockholders there shall be no: (a) change in the number
of shares of Common Stock that may be issued under the Plan, except by operation of the provisions of Section 10, either to any
one participant or in the aggregate; (b) change in the class of persons eligible to receive Options, Stock Award or Other Rights;
or (c) other change in the Plan that requires stockholder approval under applicable law or regulation. No amendment shall adversely
affect outstanding Options (or Stock Awards or Other Rights) without the consent of the Optionee (or holder of the Stock Award
or Other Right). The Plan may be terminated at any time by action of the Board, but any such termination will not terminate any
Option, Stock Award or Other Right then outstanding without the consent of the Optionee or the holder of such Stock Award or Other
Right.
