provisions contained herein:


 


(1) “including” means including, without limitation;


 


(2) “may” is not mandatory and shall not create any limitation;


 


(3) all references to $, dollars, cash payments or money refer to United States currency; and


 


(4) unless the context requires otherwise, all references to payments of interest on the Notes will include any Special Interest
payable pursuant to Section 6.04 hereof and additional interest payable pursuant to Section 2.04 hereof.


 





Section 1.05 Acts of Holders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by the Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an
agent duly appointed in writing; and, except as herein otherwise expressly provided, such action will become effective when such
instrument or instruments are delivered to the Trustee and to the Company. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing appointing any such agent will be sufficient for any purpose
of this Supplemental


 


Indenture and conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Section 1.05.


 






    	7



    	 



    

 


The fact and date of the execution by any
person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a
notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such
instrument or writing acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity
other than such signer’s individual capacity, such certificate or affidavit will also constitute sufficient proof of such
signer’s authority. The fact and date of the execution of any such instrument or writing, or the authority of the person
executing the same, may also be proved in any other manner that the Trustee deems sufficient.


 


The ownership of the Notes shall be proved
by the Register.


 


Any request, demand, authorization, direction,
notice, consent, waiver or other Act of the Holder of any Note will bind every future Holder of the same Note and the Holder of
every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done,
omitted or suffered to be done by the Trustee, the Company, the Paying Agent, the Conversion Agent or the Registrar in reliance
thereon, whether or not notation of such action is made upon such Note.


 


If the Company will solicit from the Holders
any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant
to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Company will have no obligation to do so. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date,
but only the Holders of record at the Close of Business on such record date will be deemed to be Holders for the purposes of determining
whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes will be computed as
of such record date; provided that no such authorization, agreement or consent by the Holders on such record date will be
deemed effective unless it will become effective pursuant to the provisions of this Supplemental Indenture not later than six months
after the record date.


 





Article

THE NOTES


 


Article 2 (The Securities) of the Base Indenture
is hereby amended and restated in full, with respect to the Notes, to read as follows:


 


Section 2.01 Notes Designation, Amount
and Issuance of Notes. The Notes will be designated as “Variable Interest Convertible Senior Notes due 2020.”
The aggregate principal amount of Notes that initially may be authenticated and delivered under this Supplemental Indenture is
limited to $258,750,000. From time to time, the Company may, without the consent of the Holders, issue additional Notes under
the Indenture with the same terms (except for original issuance date and, possibly, the initial interest accrual date and initial
Interest Payment Date) and with the same CUSIP numbers as the Notes issued on the Issue Date in an unlimited aggregate principal
amount; provided, however, that if such additional Notes are not fungible with the Notes issued on the Issue Date for federal
income tax purposes, they will have a separate CUSIP number. From time to time, the Company may issue and execute, and the Trustee
may authenticate, Notes delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to
Sections 2.09, 2.10, 2.11, 3.06 and 9.02(c) hereof. The registered Holder of a Note will be deemed as the owner of the Note for
all purposes under the Indenture.

or endorsements required by any applicable law (or regulation promulgated thereunder), stock exchange rule or usage, or any insertions,
omissions or other variations otherwise permitted or required by the Indenture. Whenever any such notation, legend or endorsement,
or any such insertion, omission or other variation is applicable to a Note, the Company will provide such notation, legend or endorsement,
or such insertion, omission or other variation to the Trustee in writing.


 


Each Note will bear a Trustee’s certificate
of authentication substantially in the form set forth in Exhibit A hereto.


 


Notes that are Global Notes will bear the
Global Notes Legend and the “Schedule of Exchanges of Interests in the Global Note” attached thereto.


 


The terms and provisions contained in the
Notes will constitute, and are hereby expressly made, a part of the Indenture and, to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be
bound thereby. However, to the extent that any provision of any Note conflicts with the express provisions of the Indenture, the
provisions of the Indenture will govern and control.


 


(b) Initial and Subsequent Notes. The Notes initially will be issued in global form, registered in the name of Cede &
Co., as the nominee of the Depositary, and deposited with the Trustee, at its Corporate Trust Office, as custodian for the Depositary.
Except to the extent provided in Section 2.09(c) hereof, all Notes will be represented by one or more Global Notes.


 


(c) Global Notes. Each Global Note will represent the aggregate principal amount of then outstanding Notes endorsed thereon
and provide that it represents such aggregate principal amount of then outstanding Notes, which aggregate principal amount may,
from time to time, be reduced or increased to reflect transfers, exchanges, conversions, redemptions or repurchases by the Company.


 


Only the Trustee, or the custodian holding
such Global Note for the Depositary, at the direction of the Trustee, may endorse a Global Note to reflect the amount of any increase
or decrease in the aggregate principal amount of then outstanding Notes represented thereby, and whenever the Holder of a Global
Note delivers instructions to the Trustee to increase or decrease the aggregate principal amount of then outstanding Notes represented
by a Global Note in accordance with Section 2.09 hereof, the Trustee, or the custodian holding such Global Note for the Depositary,
at the direction of the Trustee, will endorse such Global Note to reflect such increase or decrease in the aggregate principal
amount of then outstanding Notes represented thereby. None of the Trustee, the Company or any agent of the Trustee or the Company
will have any responsibility or bear any liability for any aspect of the records relating to, or payments made on account of, the
ownership of any beneficial interest in a Global Note or with respect to maintaining, supervising or reviewing any records relating
to such beneficial interest.

Neither any member of, or participant in,
the Depositary (collectively, the “Agent Members”) nor any other person on whose behalf an Agent Member may
act will have any rights under the Indenture with respect to any Global Note or under such Global Note, and the Company, the Trustee
and any agent of the Company or the Trustee, may, for all purposes, treat the Depositary, or its nominee, if any, as the absolute
owner and Holder of such Global Note.


 


The Holder of a Global Note may grant proxies
and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take
any action that Holders are entitled to take under the Indenture or the Notes, and, notwithstanding the foregoing, nothing herein
will prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary,
its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such persons
governing the exercise of the rights of a Holder of any interest in any Note.


 


Neither the Trustee nor any of its agents
shall have any responsibility or liability for any actions taken or not taken by the Depositary.


 





Section 2.03 Denomination of Notes. The Notes will be
issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples of $1,000 in excess
thereof.


  


Section
2.04 Payments.


 


(a) General.


 


(i) Payment at Maturity. Unless earlier paid or deemed paid pursuant to any of Sections 3.05 or 9.03 hereof, the Notes
will mature on April 15, 2020 (the “Maturity Date”) and, on the Maturity Date, the Company will pay each Holder
of Notes $1,000 in cash for each $1,000 principal amount of Notes held, together with accrued and unpaid interest (including any
applicable Dividend Pass-Through Payment) on such Notes to, but not including, the Maturity Date.


 


(ii) Payment of Interest. The Notes will bear cash interest at a rate of 1.75% per annum (the “Fixed Interest”),
with an additional cash payment payable on the Notes on each Interest Payment Date equal to the product of (i) the amount of cash
dividends per share actually paid by the Company on the outstanding Common Stock during the prior three-month period ending on
the Regular Record Date for such interest payment and (ii) the applicable Conversion Rate on such Regular Record Date (the “Dividend
Pass-Through Payment,” together with the Fixed Interest, the “Total Interest”). Notwithstanding the
foregoing, however, (A) the amount payable on each Interest Payment Date, other than the initial Interest Payment Date, will be
the higher of (i) the Total Interest and (ii) 5.50% per annum (the “Floor Interest Rate”) and (B) the interest
payable on the initial Interest Payment Date will be based solely on the Floor Interest Rate. The Fixed Interest or the Floor Interest
Rate, as applicable, on the Notes will accrue from the Issue Date or from the most recent date to which interest has been paid
or duly provided for, to the date the principal amount of such Note is paid or deemed paid, as the case may be, pursuant to clause
(i) of this Section 2.04(a) or any of Sections 3.05 or 9.03 hereof.


 






    	10



    	 



    

 


In addition, if the Notes would otherwise
constitute “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Internal Revenue
Code of 1986, as amended, on each Interest Payment Date on or after April 15, 2019, the Company will pay additional interest on
a Note in an amount equal to the amount required to be paid to prevent such Note from being treated as an applicable high yield
discount obligation.


 


Interest (including any applicable Dividend
Pass-Through Payment) will be payable quarterly in arrears in cash on January 15, April 15, July 15 and October 15 of each year
(each, an “Interest Payment Date”), beginning April 15, 2014, to the Holder of each such Note as of the Close
of Business on the January 1, April 1, July 1 or October 1, as the case may be, immediately preceding the applicable Interest Payment
Date (each such date, a “Regular Record Date”), regardless of whether such Note is converted or repurchased
after such Regular Record Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.


 


Payments of the Fundamental Change Repurchase
Price, principal and interest (including any Dividend Pass-Through Payment, if applicable) that are not made when due will accrue
interest at an annual rate equal to the then-applicable interest rate plus one percent from the applicable payment date.


 


(iii) Method of Payment. The Company will pay the principal of, the Fundamental Change Repurchase Price for, and the interest
(including any applicable Dividend Pass-Through Payment) on, any Global Note to the Depositary by wire transfer of immediately
available funds on the relevant payment date.


 


The Company will pay the principal of, the
Fundamental Change Repurchase Price for, and any interest (including any applicable Dividend Pass-Through Payment) due on the Maturity
Date on, any Definitive Note in cash to the applicable Holder of such Note at the office of the Paying Agent on the relevant payment
date.


 


The Company will pay interest (including
any applicable Dividend Pass-Through Payment) on any Definitive Note (except such interest due on the Maturity Date) to the applicable
Holder of such Note (i) if such Holder holds $5,000,000 or less aggregate principal amount of Notes, by check mailed to such Holder’s
registered address, and (ii) if such Holder holds more than $5,000,000 aggregate principal amount of Notes, (A) by check mailed
to such Holder’s registered address or, (B) if such Holder delivers to the Registrar a written request that the Company make
such payments by wire transfer to an account of such Holder within the United States, for each such interest payment corresponding
to each Regular Record Date occurring during the period beginning on the date on which such Holder delivered such request and ending
on the date, if any, on which such Holder delivers to the Registrar a written instruction to the contrary, by wire transfer of
immediately available funds to the account specified by such Holder.

(b) Interest Rights Preserved. Subject to the provisions of Sections 2.09 and 2.10 hereof, to the extent applicable,
each Note delivered under the Indenture upon registration of transfer of, or in exchange for, or in lieu of, any other Note will
carry any rights to the payment and accrual of interest that were carried by the relevant surrendered Note, Notes, or portion(s)
thereof.


 


Section
2.05 Execution and
Authentication.


 


(a) In General. A Note will be valid only if executed by the Company and authenticated by the Trustee.


 


(b) Execution. A Note will be deemed to have been executed by the Company when an Officer signs such Note on behalf of
the Company. The Officer’s signature may be manual or facsimile, and the validity of such Officer’s signature will
not turn on whether such signatory remains an Officer at the time the Trustee authenticates such Note.


 


(c) Authentication. A Note will be deemed authenticated when an authorized signatory of the Trustee manually signs the
certificate of authentication on such Note. An authorized signatory of the Trustee will manually sign the certificate of authentication
on a Note only if (i) the Company delivers such Note to the Trustee, (ii) such Note is validly executed by the Company in accordance
with Section 2.05(b) hereof, and (iii) the Company delivers, before or with such Note, a Company Order setting forth (A) a request
that the Trustee authenticate such Note; (B) the principal amount of such Note; (C) the name of the Holder of such Note, (D) the
date on which such Note is to be authenticated; and (E) any insertions, omissions or other variations, notations, legends or endorsements
permitted under Section 2.02 hereof and applicable to such Note. If the Company Order also specifies that the Trustee must deliver
such Note to the Holder or the Depositary, the Trustee will promptly deliver such Note in accordance with such Company Order.


 


The Trustee may appoint an authenticating
agent. If the Trustee appoints an authenticating agent and such authenticating agent is acceptable to the Company, such authenticating
agent may authenticate a Note whenever the Trustee may authenticate such Note. For purposes of this provision, each reference in
this Supplemental Indenture to authentication by the Trustee will be deemed to include authentication by an authenticating agent,
and an authenticating agent will have the same rights to deal with the Company as the Trustee would have if it were performing
the duties that the authentication agent was validly appointed to undertake.


 


Section
2.06 Registrar,
Paying Agent and Conversion Agent.


 


(a) General. The Company will maintain an office or agency in the continental United States where Notes may be presented
for registration of transfer or for exchange (the “Registrar”), an office or agency where the Notes may be presented
for payment or repurchase (the “Paying Agent”), an office or agency where the Notes may be presented for conversion
(the “Conversion Agent”) and an office or agency where notices and demands to, or upon, the Company with respect
to the Notes and the Indenture may be served.


 






    	12



    	 



    

 


The Registrar will keep a register for the
recordation of, and will record, the names and addresses of Holders, the Notes held by each Holder and the transfer, exchange,
repurchase, and conversion of Notes (the “Register”). The entries in the Register will be conclusive, and the
parties may treat each person whose name is recorded in the Register pursuant to the terms hereof as a Holder hereunder for all
purposes of the Indenture. The Register will be in written form or in any form capable of being converted into written form within
a reasonably prompt period of time.


 


The Company may have one or more registrars,
one or more paying agents, one or more conversion agents and one or more places where notices and demands to, or upon, the Company
with respect to the Notes and the Indenture may be served. Before appointing any Registrar, Paying Agent or Conversion Agent that
is not otherwise a party to this agreement, the Company will enter into an appropriate agency agreement with such Registrar, Paying
Agent or Conversion Agent, as the case may be, which agency agreement will implement the provisions of the Indenture that relate
to such replacement or additional registrar, paying agent or conversion agent, as the case may be. The term Registrar includes
any additional registrars named pursuant to this Supplemental Indenture. The term Paying Agent includes any additional paying agent
named pursuant to this Supplemental Indenture. The term Conversion Agent includes any additional conversion agent named pursuant
to this Supplemental Indenture.


 


(b) Initial Designations. The Company initially appoints the Trustee as each of the Registrar, the Paying Agent and the
Conversion Agent, and the Notes initially may be presented for registration of transfer or for exchange, payment, repurchase, and
conversion to the Trustee, in its capacity as the Registrar, Paying Agent or Conversion Agent, as the case may be, at the Corporate
Trust Office. Notices and demands to, or upon, the Company with respect to the Notes and the Indenture may be served at the Corporate
Trust Office.


 


(c) Removal, Resignation and Replacement. The Company may remove any Registrar, Paying Agent or Conversion Agent by delivering
written notice to the Trustee and to such Registrar, Paying Agent or Conversion Agent; provided, however, that no
such removal will become effective unless (i) after such removal, at least one Registrar, Paying Agent and Conversion Agent will
remain; (ii) a successor has accepted appointment as Registrar, Paying Agent or Conversion Agent, as the case may be, the Company
and such successor have entered into an agency agreement in accordance with Section 2.06(a) hereof, and the Company has delivered
written notice of such appointment and a copy of such agency agreement to the Trustee, or (iii) the Company has delivered written
notice to the Trustee that the Trustee will serve as the successor Registrar, Paying Agent or Conversion Agent, as the case may
be, in accordance with Section 2.06(e) hereof; and provided, further, that the right to effect any such change or
removal in no way relieves the Company of its obligation to maintain a Registrar, Paying Agent and Conversion Agent in the continental
United States. The Company may also change the place where notices and demands to, or upon, the Company with respect to the Notes
and the Indenture may be served, or reduce the number of such places; provided, however, that the right to effect
any such change or reduction in no way relieves the Company of its obligation to maintain a place in the continental United States
where notices and demands to, or upon, the Company with respect to the Notes and the Indenture may be served.


 






    	13



    	 



    

 


In addition, the Registrar, Paying Agent
or Conversion Agent may resign at any time by delivering written notice of such resignation to each of the Company and the Trustee;
provided, however, that if the Trustee is serving as Registrar, Paying Agent or Conversion Agent, the Trustee may
resign from such capacity only if it also resigns as Trustee in accordance with Section 7.8 of the Base Indenture. If, after any
such resignation, at least one Registrar, Paying Agent and Conversion Agent does not remain, the Trustee will immediately be deemed
to serve such empty office or agency in accordance with Section 2.06(d) hereof.


 


(d) Failure to Maintain an Office or Agency. If the Company fails to maintain in the continental United States, a Registrar,
Paying Agent, Conversion Agent or place where notices and demands to, or upon, the Company with respect to the Notes and the Indenture
may be served, the Trustee will act as the Registrar, Paying Agent, Conversion Agent, or place, as the case may be, and the office
where the Notes may be presented for registration of transfer or for exchange, presented for payment, repurchased or surrendered
for conversion, or place where notices and demands to, or upon, the Company with respect to the Notes and the Indenture may be
served, as the case may be, will be the Corporate Trust Office. In each such case, the Trustee will be entitled to compensation
for such action pursuant to Section 7.7 of the Base Indenture.


 


(e) Notices. Promptly upon the effectiveness of any removal or subsequent appointment of a Registrar, Paying Agent or
Conversion Agent, or upon any change in the location of the office of any Registrar, Paying Agent or Conversion Agent, or of the
place where notices and demands to, or upon, the Company with respect to the Notes and the Indenture may be served, the Company
will deliver to the Trustee notice of such removal, appointment or change in location, as the case may be, which notice will include
a brief description of the removal, appointment or change in location, as the case may be, and list the name and address of each
continuing (and newly appointed, if applicable) Registrar, Paying Agent and Conversion Agent and place where notices and demands
to, or upon, the Company with respect to the Notes and the Indenture may be served.


 





Section 2.07 Money and Securities Held in Trust.
Except as otherwise provided herein, by no later than 10:00 a.m., New York City time, on each due date for a payment on any Note,
the Company will deposit with the Paying Agent an amount of money in immediately available funds, if deposited on the due date,
sufficient to make such payment when due.


  


The Company will require that each Paying
Agent (other than the Trustee, if the Trustee is a Paying Agent) agree in writing that it will (i) segregate all money and securities
it holds for making payments with respect to the Notes; (ii) hold such money and securities in trust for the benefit of Holders;
and (iii) notify the Trustee, in writing, as promptly as practicable, if the Company defaults in making any payment on the Notes.


 


If any such payment default has occurred
and is continuing, the Paying Agent will, upon receiving a written request from the Trustee, forthwith pay to the Trustee all of
the money and securities it holds in trust. In addition, at any time, the Company may require a Paying Agent to pay all money and
securities that it holds for making payments with respect to the Notes to the Trustee and to account for any money and securities
it has disbursed. After delivering all of such money and securities to the Trustee pursuant to this Section 2.07, the Paying Agent
will have no further liability for such money and securities.

Section 2.08 Holder Lists. The Trustee will preserve
in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If
the Trustee is not the Registrar, the Company shall furnish to the Trustee, promptly after each Regular Record Date, and at such
other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require
of the names and addresses of Holders.

(iii) No service charge will be imposed on any Holder of a Definitive Note or any owner of a beneficial interest in a Global Note

in connection with such registration of transfer or exchange.


 


(iv) Unless the Company specifies otherwise, none of the Company, the Trustee or the Registrar will be required to exchange or
register a transfer of any Note (i) surrendered for conversion, except to the extent that any portion of such Note has not been
surrendered for conversion, or (ii) subject to a Fundamental Change Repurchase Notice validly delivered pursuant to Section 3.03
hereof, except to the extent any portion of such Note is not subject to a Fundamental Change Repurchase Notice.


 


(v) The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Note (including
any transfers between or among Depositary participants 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 Supplemental Indenture, and to examine the same to determine substantial compliance as to form with
the express requirements hereof.

Note will be at any time enforceable by anyone, and will be entitled to all benefits of (and will be subject to all the limitations
set forth in) the Indenture equally and proportionately with any and all other Notes duly issued hereunder.


 


The provisions of this Section are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Notes.


 





Section 2.11 Temporary Notes. Until Definitive Notes
are ready for delivery, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee will, upon
written request of the Company, authenticate and deliver temporary Notes (printed or lithographed) (“Temporary Notes”).
Temporary Notes will be issuable in any authorized denomination, and substantially in the form of Definitive 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 will 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 Definitive Notes. Without unreasonable delay
the Company will prepare, execute and deliver to the Trustee or such authenticating agent Definitive 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 2.06 hereof and the Trustee or such authenticating agent will authenticate
and deliver, in exchange for such Temporary Notes, Definitive Notes having an aggregate principal amount equal to such Temporary
Notes. Until so exchanged, the Temporary Notes will, in all respects, be entitled to the same benefits and subject to the same
limitations under the Indenture as Definitive Notes authenticated and delivered hereunder.


  





Section 2.12 Cancellation. At any
time, the Company may deliver Notes to the Trustee for cancellation. Whenever any Note is surrendered to the Registrar, Conversion
Agent or Paying Agent for registration of transfer, exchange, conversion, repurchase, or payment, the Registrar, Conversion Agent
or Paying Agent, as the case may be, will promptly forward such Note to the Trustee. Upon receipt of any such Note, the Trustee,
in its customary manner, will promptly cancel and dispose of such Note and deliver a certificate of such cancellation to the Company
upon written request of the Company. The Company may not issue new Notes to replace Notes that it has repurchased, paid or delivered
to the Trustee for cancellation or that a Holder has converted pursuant to Article 9 hereof.

Section 2.13 Outstanding Notes. At any time, Notes outstanding
are limited to all Notes authenticated by the Trustee except (i) those cancelled by it, (ii) those delivered to it for cancellation
and (iii) those deemed not outstanding under Sections 3.05 and 9.02 hereof and clauses (a) and (b) of this Section 2.13.


  


(a) If a Note is replaced pursuant to Section 2.10 hereof, such Note will cease to be outstanding at the time of its replacement
unless the Trustee and the Company receive proof satisfactory to them that such Note is held by a bona fide purchaser.


 


(b) In addition, if the Company or an Affiliate of the Company holds a Note, such Note will be disregarded and deemed not to
be outstanding for purposes of determining whether the Holders of the requisite aggregate principal amount of Notes have given
or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, except that for
the purposes of determining whether the Trustee shall be protected in conclusively relying on any such request, demand, authorization,
direction, notice, consent or waiver, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be
so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee’s right to deliver any such request, demand, authorization, direction, notice, consent
or waiver with respect to the Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate
of the Company or of such other obligor. Subject to the foregoing, only Notes outstanding at the time of any such determination
will be considered in such determination (including determinations pursuant to Articles 6 and 9 hereof).


 





Section 2.14 Persons Deemed Owners.
Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving
the payment of the principal, the Fundamental Change Repurchase Price of, and interest, if any, on, such Note, for the purpose
of conversion of such Note and for all other purposes whatsoever with respect to such Note, and none of the Company, the Trustee
or any agent of the Company or the Trustee will be affected by any notice to the contrary.


 


Section 2.15 Repurchases. The Company may, from time
to time, at its option, repurchase Notes in open market purchases or in negotiated transactions without delivering prior notice
to Holders.


  


Section
2.16 CUSIP and ISIN
Numbers.


 


(a) The Company in issuing the Notes may use “CUSIP” or “ISIN” numbers (if then generally in use). The
Company will promptly notify the Trustee in writing of any change in the CUSIP or ISIN numbers.


 






    	20



    	 



    

 


(b) In addition, if, when any shares of Common Stock are issued upon conversion of a Note, CUSIP and ISIN numbers are generally
in use, the Company will use CUSIP and ISIN numbers with respect to such shares of Common Stock.


 


(c) Whenever any of the CUSIP numbers with respect to the Notes or the shares of Common Stock issuable upon conversion of the
Notes changes, ceases to be used, or begins to be used, the Company will deliver prompt written notice of such change, cessation,
or beginning to each of the Trustee and the Holders.

at such Holder’s option, to require the Company to repurchase for cash all, or any portion, of its Notes in principal amount
equal to $1,000 or an integral multiple of $1,000 on the Fundamental Change Repurchase Date for such Fundamental Change for an
amount of cash equal to the corresponding Fundamental Change Repurchase Price.

and such Dividend Pass-Through Payment will be calculated based on the amount of cash dividends per share actually paid by the
Company on the outstanding Common Stock during the period commencing on the most recent prior Record Date and ending on the Fundamental
Change Repurchase Date and will be pro rated by multiplying the amount otherwise payable by a fraction, the numerator of which
is the number of days during the period from and including the most recent prior Record Date to, but excluding, the Fundamental
Change Repurchase Date and the denominator of which is 90) and the Floor Interest Rate) to, but excluding, such Fundamental Change
Repurchase Date; provided, however, that if a Fundamental Change Repurchase Date occurs after a Regular Record Date,
but on or prior to the corresponding Interest Payment Date, the Company will pay the full amount of such accrued and unpaid interest
on such Notes on such Interest Payment Date to the Holder of such Notes as of the Close of Business on the corresponding Regular
Record Date and the Fundamental Change Repurchase Price will equal 100% of the principal amount of such Notes.


 


(c) Fundamental Change Repurchase Date. The “Fundamental Change Repurchase Date” means, for any Fundamental
Change, the date specified by the Company in the Fundamental Change Notice for such Fundamental Change, which date will be not

or cause to be delivered, to each Holder (and to any beneficial owners of a Global Note, as required by applicable law), the Trustee
and the Paying Agent written notice of the occurrence of such Fundamental Change and the resulting fundamental change repurchase
right (the “Fundamental Change Notice,” and the date of such mailing or delivery, the “Fundamental
Change Notice Date”). Simultaneously with sending any Fundamental Change Notice to the Holders, the Trustee and the Paying
Agent, the Company will publish a notice containing the same information as the Fundamental Change Notice on its website or through
such other public medium as the Company may use at such time.


 


For any Fundamental Change, the Fundamental

(A) the events causing such Fundamental Change;


 


(B) the effective date of such Fundamental Change;

    	22

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


 


(K) the procedures for withdrawing a Fundamental Change Repurchase Notice;


 


(L) that if a Note or portion of a Note is subject to a validly delivered Fundamental Change Repurchase Notice, unless the Company
defaults in paying the Fundamental Change Repurchase Price for such Note or portion of a Note, interest, if any, on such Note or
portion of a Note will cease to accrue on and after the Fundamental Change Repurchase Date; and


 


(M) the CUSIP and ISIN number(s) of the Notes.


 


(b) Failure or Defect. Notwithstanding anything provided elsewhere in the Indenture, neither the failure of the Company
to deliver a Fundamental Change Notice nor a defect in a Fundamental Change Notice delivered by the Company will limit the repurchase
rights of any Holder under this Article 3 or impair or otherwise affect the validity of any proceedings relating to the repurchase
of any Note pursuant to this Article 3.


 


Section
3.03 Fundamental
Change Repurchase Notice.


 


(a) General. To exercise its repurchase rights under Section 3.01(a) hereof with respect to any Fundamental Change, a

Order, the Trustee, in accordance with Section 2.05 hereof, will promptly authenticate and deliver, to the surrendering Holder,
a new Note or Notes of any authorized denomination or denominations requested by such Holder in aggregate principal amount equal

(a) General. Notwithstanding anything to the contrary in this Article 3, the Company will not purchase any Notes under
this Article 3 if, as of the Fundamental Change Repurchase Date, the principal amount of the Notes has been accelerated, such acceleration

the Fundamental Change Repurchase Price.


 


(b) Deemed Withdrawals. If, on any Fundamental Change Repurchase Date, (i) a Fundamental Change Repurchase Notice for
a Note has been validly tendered in accordance with Section 3.03 hereof and has not been validly withdrawn in accordance with Section

    	30



    	 



    

 


The Company will, so long as any of the
Notes are outstanding, deliver to the Trustee, within 30 days of becoming aware of any Default or Event of Default, an Officer’s
Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect
thereto.


 


Section
6.02 Acceleration.


 


(a) Automatic Acceleration in Certain Circumstances. If an Event of Default specified in Sections 6.01(ix) or 6.01(x)
hereof occurs with respect to the Company (but not any of the Significant Subsidiaries), the principal amount of, and all accrued
and unpaid interest (including any applicable Dividend Pass-Through Payment), if any, on, all of the then outstanding Notes will
immediately become due and payable without any further action or notice by any party.


 


(b) Optional Acceleration. If any Event of Default (other than an Event of Default specified in Sections 6.01(ix) or
6.01(x) hereof with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding may declare the principal amount of, and all accrued and unpaid interest, if any, on all then
outstanding Notes (calculated at the greater of the Total Interest (with the date of acceleration treated as an Interest Payment
Date for purposes of calculating the Dividend Pass-Through Payment payable as a component thereof and such Dividend Pass-Through
Payment shall be calculated based on the amount of cash dividends per share actually paid by the Company on the outstanding Common
Stock during the period commencing on the most recent prior Record Date and ending on the date of acceleration and will be pro
rated by multiplying the amount otherwise payable by a fraction, the numerator of which is the number of days during the period
from and including the most recent prior Record Date to, but excluding, the date of acceleration and the denominator of which is
the number of days in the three-month period ending on the Record Date for the next scheduled interest payment) and the Floor Interest
Rate) to be immediately due and payable by delivering written notice to the Company, and upon such declaration, the principal amount
of, and all accrued and unpaid interest (including any Dividend Pass-Through Payment), if any, on all then outstanding Notes will
immediately become due and payable.


 


(c) Rescission of Acceleration. Notwithstanding anything to the contrary in the Indenture, the Holders of a majority
of the aggregate principal amount of the then outstanding Notes may, on behalf of the Holders of all of the then outstanding Notes,
rescind any acceleration of the Notes and its consequences hereunder by delivering written notice to the Company and the Trustee
if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) any and all
existing Events of Default, other than the nonpayment of the principal of, the Fundamental Change Repurchase Price for, or any
interest on, the Notes that has become due solely as a result of acceleration, have been cured or waived. No such rescission will
affect any subsequent Default.


 






    	31



    	 



    

 





Section 6.03 Other Remedies. If an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, accrued and unpaid interest
(including any applicable Dividend Pass-Through Payment), if any, or payment of the Fundamental Change Repurchase Price for, the
Notes or to enforce the performance of any provision of the Notes or the Indenture regarding any other matter.





 


The Trustee may maintain a proceeding even
if it does not possess any of the Notes or does not produce any of the Notes in the proceeding. A delay or omission by the Trustee
or any Holder in exercising any right or remedy accruing upon an Event of Default will not impair the right or remedy or constitute
a waiver of or acquiescence in the Event of Default. Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in Section 2.10 or at the Company’s election with respect to a Reporting
Event of Default pursuant to Section 6.04, no remedy is exclusive of any other remedy. All available remedies are cumulative.


 


Section
6.04 Sole Remedy
for Failure to Report.


 


(a) General. Notwithstanding anything to the contrary in the Notes or in the Indenture, the Company may elect that the
sole remedy for any Event of Default specified in Section 6.01(vi) hereof relating to the Company’s failure to comply with
the reporting obligations under Section 4.02 hereof (a “Reporting Event of Default”) will, for the period beginning
on the date on which such Reporting Event of Default first occurred (taking into account the 60 day grace period set forth in Section
6.01(vi) hereof) and ending on the earlier of (A) the date on which such Reporting Event of Default is cured or validly waived
in accordance with Section 6.05 hereof and (B) the 365th day immediately following the date on which such Reporting Event of Default
first occurred, consist exclusively of the right to receive additional interest (the “Special Interest”) on
the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes for the first 90 days and at a rate equal to
0.50% per annum of the principal amount of the Notes from the 91st day until the 365th day. If the Company elects, the Special
Interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 365th day
immediately following, and including, the date on which such Reporting Event of Default first occurred, if the Special Interest
has not previously ceased to accrue, the Special Interest will cease to accrue.


 


(b) Limitation on Remedy. If (i) a Reporting Event of Default occurs and the Company elects that the sole remedy with
respect to such Reporting Event of Default will be the payment of Special Interest and (ii) on the 365th day immediately following,
and including, the date on which such Reporting Event of Default first occurred, such Reporting Event of Default has not been cured
or validly waived in accordance with Section 6.05 hereof, then the Notes will become subject to acceleration under Section 6.02(b)
hereof on account of such Reporting Event of Default.


 


(c) Company Election Notice. To elect to pay the Special Interest as the sole remedy for a Reporting Event of Default,
the Company must deliver written notice of such election to the Holders, the Paying Agent and the Trustee prior to the date that
is 60 days after the notice of such Reporting Event of Default is given to the Company by the Trustee or Holders of at least 25%
in principal amount of outstanding Notes. The Trustee and the Paying Agent shall not at any time be under any duty or responsibility
to any Holder to determine the Special Interest, or with respect to the nature, extent, or calculation of the amount of Special
Interest owed, or with respect to the method employed in such calculation of the Special Interest.


 






    	32



    	 



    

 


If a Reporting Event of Default occurs and
the Company fails to timely deliver such notice for such Reporting Event of Default, the Notes will be subject to acceleration
under Section 6.02(b) hereof on account of such Reporting Event of Default.


 


(d) Other Events of Default. Notwithstanding anything to the contrary herein, if the Company elects to pay the Special
Interest with respect to any Reporting Event of Default, the Company’s election will not affect the rights of any Holder
with respect to any other Event of Default. For the avoidance of doubt, in no event will the Company be obligated to pay the Special
Interest at a rate greater than 0.50% per annum on the principal amount of then outstanding Notes, regardless of the number of
events or circumstances giving rise to requirements to pay such Special Interest.


 





Section 6.05 Waiver of Past Defaults.
If an Event of Default described in Sections 6.01(i), 6.01(ii), 6.01(iv) or 6.01(vi) (which, in the case of Section 6.01(vi) only,
relates to a covenant that cannot be amended without the consent of each affected Holder) or a Default that would lead to such
an Event of Default occurs and is continuing, such Event of Default or Default may be waived only with the consent of each affected
Holder. Every other Event of Default or Default may be waived, and any acceleration of the Notes and the consequences thereof following
any such Event of Default may be rescinded, by the Holders of a majority of the aggregate principal amount of then outstanding
Notes. Whenever any Event of Default is so waived, it will cease to exist, and whenever any Default is so waived, it will be deemed
cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent
or other Default or Event of Default or impair any consequent right.


 


Section 6.06 Control by Majority.
At any time, the Holders of a majority of the aggregate principal amount of then outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on
the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture
or, subject to Section 7.1 of the Base Indenture, that the Trustee determines to be unduly prejudicial to the rights of any other
Holder or that would involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee will be entitled
to indemnification satisfactory to it against all losses and expenses caused by taking or not taking such action.


 


Section 6.07 Limitation on Suits.
Except (i) to enforce its rights to receive the principal of, the Fundamental Change Repurchase Price for, or interest, if any,
on, a Note, or (ii) following the failure of the Company to comply with its obligations under Article 9 to convert any Note, no
Holder may pursue a remedy with respect to the Indenture or the Notes unless:


 


(a) such Holder has previously delivered to the Trustee written notice that an Event of Default has occurred and is continuing;


 






    	33



    	 



    




 


(b) the Holders of not less than 25% of the aggregate principal amount of then outstanding Notes have made to the Trustee a
written request that the Trustee institute the proceedings with respect to such Event of Default in its own name as Trustee under
the Indenture;


 


(c) such Holder or Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs,
expenses and liabilities which might be incurred by the Trustee in compliance with such request;


 


(d) the Trustee has failed to institute any such proceeding for 60 days after its receipt of such written notice, request and
offer of indemnity; and


 


(e) no direction, in the opinion of the Trustee, inconsistent with such written request has been given to the Trustee during
such 60-day period by Holders of a majority in principal amount of the Notes.


 


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


 


Section 6.08 Rights of Holders to Receive
Payment. Notwithstanding any other provision of the Indenture, the right of any Holder to receive payment of the principal
of, the Fundamental Change Repurchase Price for, accrued and unpaid interest (including any applicable Dividend Pass-Through Payment),
if any, on, and any consideration due under Article 9 upon conversion of, its Note, on or after the respective due date, or to
bring suit for the enforcement of any such payment and/or delivery on or after the respective due date, will not be impaired or
affected without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof.


 


Section 6.09 Collection Suit by Trustee.
If an Event of Default specified in Section 6.01(i), 6.01(ii) or 6.01(iv) hereof occurs and is continuing, the Trustee is authorized
to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of,
the Fundamental Change Repurchase Price for, and interest, if any, on, the Notes, and such further amount as is sufficient to cover
the costs and expenses of collection provided for under Section 7.7 of the Base Indenture.


 


Section 6.10 Trustee May File Proofs
of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable
to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money
or other property payable or deliverable on any such claims, and any Custodian in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee, and in the event that the Trustee consents to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 of the Base Indenture.
To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due to the Trustee under Section 7.7 of the Base Indenture out of the estate in any such proceeding, will
be denied for any reason, payment of the same will be secured by a lien on, and will be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation
or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee
to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment
or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of
any Holder in any such proceeding.


 






    	34



    	 



    

 


Section 6.11 Priorities. Any money and property collected
by the Trustee pursuant to this Article 6 shall be applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money and property to Holders, upon presentation of the Notes and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:


 







FIRST: to the Trustee, its agents and attorneys
for amounts due under Section 7.7 of the Base Indenture, including payment of all compensation, expenses and liabilities incurred,
and all advances made, by the Trustee and the costs and expenses of collection;


 


SECOND: to the Holders, for any amounts
due and unpaid on the principal of, the Fundamental Change Repurchase Price for, accrued and unpaid interest (including any applicable
Dividend Pass-Through Payment), if any, on, and any cash in lieu of fractional shares due upon the conversion of, any Note, without
preference or priority of any kind, according to such amounts due and payable on all of the Notes; and


 


THIRD: the balance, if any, to the Company
or to such other party as a court of competent jurisdiction directs.


 





Section 6.12 Undertaking for Costs. In any suit for the
enforcement of any right or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it
as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.12 does not apply to a suit by the Company, the Trustee, a suit by a Holder pursuant to Section 6.08 hereof
or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

SATISFACTION AND DISCHARGE


 


Article 8 (Satisfaction and Discharge; Defeasance)

Section 7.01 Discharge of Liability on Notes. When (a)(i)
the Company delivers to the Trustee all outstanding Notes (other than Notes replaced pursuant to Section 2.10 hereof) for cancellation
or (ii) all outstanding Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date,
or upon conversion or otherwise, and the Company irrevocably deposits with the Trustee or delivers to the Holders, as applicable,
cash or U.S. government obligations and/or shares of Common Stock and cash (in lieu of fractional shares of Common Stock) (solely
to satisfy amounts due and owing as a result of conversions of the Notes), sufficient to pay all amounts due and owing on all outstanding
Notes (other than Notes replaced pursuant to Section 2.10 hereof), (b) the Company pays all other sums payable by it under the
Indenture with respect to the then outstanding Notes and (c) upon demand of the Company, the Company delivers to the Trustee an
Officer’s Certificate and an Opinion of Counsel, each stating that all of the applicable conditions precedent to the discharge
of the Indenture described in this section have been satisfied, then, subject to Section 7.7 of the Base Indenture, the Indenture
will cease to be of further effect with respect to the Notes and the Holders and the Trustee will acknowledge the satisfaction
and discharge of the Indenture with respect to the Notes.


 


Notwithstanding the satisfaction and discharge
of the Indenture, (i) any obligation of the Company to any Holder under Article 9 hereof with respect to the conversion of any
Note or to the Trustee under Section 7.7 of the Base Indenture with respect to compensation or indemnity, and (ii) any obligation
of the Trustee with respect to money deposited with the Trustee under this Article 7 and Section 10.2 of the Base Indenture, will
survive.

including shares of the Common Stock, to the Company, the Trustee and the Paying Agent will have no further liability to any Holder
with respect to such cash and securities, including shares of Common Stock, and any Holder entitled to the payment of such cash
or securities, including shares of Common Stock, under the Notes or the Indenture must look to the Company for payment as a general
creditor of the Company.

With the written consent of the Holders of at least a majority of the aggregate principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a repurchase of, or tender offer or exchange offer for, Notes),
by Act of such Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, may amend
or supplement the Indenture or the Notes, or waive any past Default or Event of Default or compliance with any provision of the

It will not be necessary for the consent

sufficient if such consent approves the substance of such proposed amendment or modification.


 





Section 8.03 Execution of Supplemental
Indentures. Upon the request of the Company, the Trustee will sign any supplemental indenture authorized pursuant to this Article
8 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee under the Indenture.
If the supplemental indenture adversely affects the Trustee’s rights, duties, liabilities or immunities under the Indenture,
then the Trustee may, but need not, sign such supplemental indenture. In executing any such supplemental indenture, the Trustee
will be provided with, and, subject to the provisions of Section 7.1 of the Base Indenture, will be fully protected in conclusively
relying upon, an Officer’s Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized and

hereof becomes effective, the Company will promptly deliver written notice to the Trustee, which notice will briefly describe such
amendment or supplement to the Indenture and state the effective date of such amendment or supplement. The Company, or the Trustee,
at the direction of the Company, will then promptly deliver a copy of such notice to each Holder. The failure to deliver such notice
to each Holder, or any defect in such notice, will not impair or affect the validity of such amendment or supplement to the Indenture.


 


Section 8.05 Effect of Supplemental Indentures. Upon
the execution of any supplemental indenture under this Article 8:


 


(a) the Indenture will be modified in accordance therewith;

    	38



    	 



    

 


(c) every Holder of Notes theretofore, or thereafter, authenticated and delivered hereunder will be bound thereby.


 


Section
8.06 Revocation
and Effect of Consents, Waivers and Actions.


 


(a) Revocation. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing
consent by the Holder, and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting
Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder, or subsequent Holder, may
revoke the consent as to its Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment,
supplement or waiver becomes effective.


 


(b) Regular Record Dates. The Company may, but is not obligated to, fix a record date for the purpose of determining
the Holders entitled to give their consent or take any other action described above or required, or permitted, to be taken pursuant
to the Indenture. If a record date is fixed, then those persons who were Holders at such record date (or their duly designated
proxies), and only those persons, will be entitled to give such consent, to revoke any consent previously given or to take any
such action, regardless of whether such persons continue to be Holders after such record date. No such consent will be valid or
effective for more than 120 days after such record date.


 


(c) Binding Effect. After an amendment, supplement or waiver becomes effective, it will bind every applicable Holder.
Any amendment or supplement will become effective in accordance with the terms of the supplemental indenture relating thereto,
which will become effective upon the execution thereof by the Trustee.


 





Section 8.07 Notation on, or Exchange of, Notes. If any
amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of such Note to deliver such Note
to the Trustee. The Trustee may place an appropriate notation on such Note about the changed terms and return it to the Holder.
Alternatively, if the Company or the Trustee so determines, the Company, in exchange for the Note, will issue and the Trustee will
authenticate a new Note that reflects the changed terms.


  


Article
9

CONVERSIONS


 


Section
9.01 Right to Convert.


 


(a) In General. Subject to, and upon compliance with, the provisions of this Article 9, until the Close of Business on
the Business Day immediately preceding the Maturity Date, a Holder may, at its option, convert all of its Notes, or any portion
of its Notes having a principal amount equal to $1,000 or an integral multiple of $1,000 in excess thereof, into a number of shares
of Common Stock and an amount of cash in lieu of fractional shares of Common Stock, all as determined in accordance with Section
9.03 hereof. Notes may not be converted after the Close of Business on the Business Day immediately preceding the Maturity Date.


 


(b) Closed Periods. Notwithstanding anything to the contrary in the Indenture, if a Holder tenders a Fundamental Change
Repurchase Notice with respect to its Notes in accordance with Article 3 hereof, such Notes may not be converted except to the
extent (A) such Notes are not subject to such Fundamental Change Repurchase Notice; (B) such Fundamental Change Repurchase Notice
is withdrawn in accordance with Article 3 hereof; or (C) the Company fails to pay the Fundamental Change Repurchase Price for such
Notes in accordance with Section 3.08 hereof.


 






    	39



    	 



    

 


Section
9.02 Conversion
Procedures.


 


(a) General. To exercise its conversion right with respect to a beneficial interest in a Global Note, the owner of such
beneficial interest must (i) comply with the Applicable Procedures for converting such beneficial interest; (ii) pay any funds
equal to interest payable on the next Interest Payment Date that such Holder is required to pay under clause (d) of this Section
9.02; and (iii) pay any transfer or similar taxes or duties that such Holder is required to pay under the proviso to clause (e)
of this Section 9.02.


 


To exercise its conversion right with respect
to a Definitive Note, the Holder of such Note must (i) complete and manually sign the conversion notice in the form of Attachment
1 to the Note, or a facsimile of such conversion notice (such notice, or such facsimile, the “Conversion Notice”);
(ii) deliver such signed and completed Conversion Notice, which is irrevocable, and such Note to the Conversion Agent at its office;
(iii) furnish any endorsements and transfer documents that the Company, Conversion Agent, Trustee or Transfer Agent may require;
(iv) pay any funds equal to interest payable on the next Interest Payment Date that such Holder is required to pay under clause
(d) of this Section 9.02; and (v) pay any transfer or similar taxes or duties that such Holder is required to pay under the proviso
to clause (e) of this Section 9.02.


 


The first Business Day on which a Holder
satisfies the foregoing requirements with respect to a Note and on which conversion of such Note is not otherwise prohibited under
the Indenture will be the “Conversion Date” for such Note.


 


The conversion of any Note will be deemed
to occur at the Close of Business on the Conversion Date for such Note, and any converted Note or portion thereof will cease to
be outstanding upon conversion.


 


(b) Holder of Record. If a Holder surrenders the entire principal amount of a Note for conversion, such person will no
longer be the Holder of such Note as of the Close of Business on the Conversion Date for such Note.


 


Upon the conversion of a Note, the person
in whose name such shares of Common Stock will be registered will become the holder of record of such shares of Common Stock at
the Close of Business on the Conversion Date for such Note.


 


(c) Conversions in Part. If a Holder surrenders only a portion of the principal amount of a Definitive Note for conversion,
promptly after the Conversion Date for such portion, the Company will, in accordance with Section 2.05 hereof, execute and deliver
to the Trustee, and the Trustee will, upon receipt of a Company Order, in accordance with Section 2.05 hereof, authenticate and
deliver to such Holder a new Definitive Note in an authorized denomination, having a principal amount equal to the aggregate principal
amount of the unconverted portion of the Definitive Note surrendered for conversion and bearing registration numbers not contemporaneously
outstanding.


 






    	40



    	 



    

 


Upon the conversion of any beneficial interest
in a Global Note, the Conversion Agent will promptly request that the Trustee make a notation on the “Schedule of Increases
and Decreases of Global Note” of such Global Note to reduce the principal amount represented by such Global Note by the principal
amount of the converted beneficial interest. If all of the beneficial interests in a Global Note are so converted, such Global
Note will be deemed surrendered to the Trustee for cancellation, and the Trustee will cause such Global Note to be cancelled in
accordance with the Applicable Procedures.


 


(d) Reimbursement of Interest upon Conversion. If a Holder converts a Note after the Close of Business on a Regular Record
Date, but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must
accompany such Note with an amount of cash equal to the amount of interest, if any, that will be payable on such Note on the corresponding
Interest Payment Date; provided, however, that a Holder need not make such payment (A) for conversions following
the Regular Record Date immediately preceding the Maturity Date; (B) 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 and the Holder converts its Note after the Close of Business on such Regular Record Date and on or prior to the Open of Business
on such Interest Payment Date; or (C) to the extent of any overdue interest (including any applicable Dividend Pass-Through Payment),
if any such overdue interest exists at the time of conversion with respect to such Note.


 


(e) Taxes and Duties. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer
tax due on the issue of any shares of the Common Stock upon the conversion; provided, however, that if any tax is
due because the converting Holder requested that shares of Common Stock be issued in a name other than its own, such Holder will
pay any such documentary, stamp or similar issue or transfer tax and the Conversion Agent, until having received a sum sufficient
to pay such tax, may refuse to deliver any certificates representing the shares of Common Stock being issued in a name other than
that of such Holder.


 


(f) Notices. Whenever a Conversion Date occurs with respect to a Note, the Conversion Agent will, as promptly as possible,
and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee
notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Notes converted
on such Conversion Date and the names of the Holders that converted Notes on such Conversion Date.


 


Section
9.03 Conversion
Obligation.


 


(a) Conversion Obligation. Except as set forth in Sections 9.07 and 9.08 hereof, if a Holder surrenders all or a portion
of a Note for conversion, the Company will deliver to such Holder, on the third Business Day immediately following the Conversion
Date for such Note, (i) a number of shares of Common Stock equal to the product of (A)(x) the aggregate principal amount of such
Note to be converted divided by (y) $1,000 and (B) the Conversion Rate in effect on such Conversion Date, rounded down to
the nearest whole number, and (ii) an amount of cash equal to the product of (A) the fraction of a share of Common Stock eliminated
by such rounding and (B) the Last Reported Sale Price of the Common Stock on such Conversion Date (or if such Conversion Date is
not a Trading Day, the immediately preceding Trading Day).


 






    	41



    	 



    

 


(b) Conversion of Multiple Notes by a Single Holder. If a Holder converts more than one Note on a single Conversion Date,
the number of shares of Common Stock that the Company will deliver to the converting Holder, and the amount of cash that the Company
will pay to such Holder in lieu of fractional shares of Common Stock, will be computed based on the total principal amount of Notes
converted on such Conversion Date by such Holder.


 


(c) Settlement of Accrued Interest and Deemed Payment of Principal. If a Holder converts a Note, the Company will not
make any separate cash payment or adjust the Conversion Rate to account for any accrued and unpaid interest (including any applicable
Dividend Pass-Through Payment) on the Note, and the Company’s delivery of the number of shares of Common Stock and the amount
of cash that the Company will pay to such Holder in lieu of fractional shares of Common Stock, if any, into which a Note is convertible
will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of such Note and accrued and
unpaid interest (including any applicable Dividend Pass-Through Payment), if any, on, such Note to, but excluding, the Conversion
Date; provided, however, that if a Holder converts a Note after the Close of Business on a Regular Record Date and
prior to the Open of Business on the corresponding Interest Payment Date, the Company will still be obligated to pay the interest
due on such Interest Payment Date to the Holder of such Note as of the Close of Business on such Regular Record Date.


 


As a result, except as otherwise provided
in the proviso to the immediately preceding sentence, any accrued and unpaid interest (and any applicable Dividend Pass-Through
Payment) with respect to a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited.


 


Section
9.04 Common Stock
Issued upon Conversion.


 


(a) Prior to issuing of any shares of Common Stock under this Article 9, and from time to time thereafter as may be necessary,
the Company will reserve out of its authorized but unissued shares of Common Stock a number of shares of Common Stock sufficient
to permit the conversion of the Notes.


 


(b) Any shares of Common Stock delivered upon the conversion of the Notes will be newly issued shares or treasury shares, duly
and validly issued, fully paid, nonassessable, free from preemptive rights and free of any lien or adverse claim (except to the
extent of any lien or adverse claim created by the action or inaction of the Holder or other person to whom such shares of Common
Stock will be delivered). In addition, the Company will endeavor to comply promptly with all federal and state securities laws
regulating the offer and delivery of any shares of Common Stock issuable upon conversion of the Notes. The Company will also use
commercially reasonable efforts to cause any shares of Common Stock issuable upon conversion of a Note to be listed on whatever
stock exchange(s) the Common Stock is listed on the date the converting Holder becomes a record holder of such Common Stock.


 






    	42



    	 



    

 


Section 9.05 Adjustment of Conversion Rate. The Company
will adjust the Conversion Rate from time to time as described in this Section 9.05.


  


(a) Stock Dividends and Share Splits. If the Company issues shares of Common Stock as a dividend or distribution on shares
of the outstanding Common Stock, or if the Company effects a share split of the Common Stock or a share combination of the Common
Stock, the Conversion Rate will be adjusted based on the following formula:


 





 


Where:


 





	CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the Effective Date of such share split or share combination, as applicable;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such Effective Date;
	 	 	 
	OS0	= 	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such Effective Date; and
	 	 	 
	OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination. 







 


If any dividend or distribution of the type described in this
Section 9.05(a) is declared, but not so paid or made, the Conversion Rate will be immediately readjusted, effective as of the date
that 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 or announced.


 


Any adjustment made under this clause (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.


 


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


 






    	43



    	 



    

 





 


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;
	 	 	 
	OS	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;
	 	 	 
	X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	 	 	 
	Y	=	the number of shares of Common Stock equal to the quotient of (i) the aggregate price payable to exercise such rights, options or warrants, divided by (ii) the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.







 


Any increase made under this Section 9.05(b) will be made successively
whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the
Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights,
options or warrants, including because the issued rights, options or warrants were not exercised, the Conversion Rate will 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 will be immediately decreased to the Conversion Rate that would then be in effect
if the Ex-Dividend Date for such issuance had not occurred.


 


For purposes of this Section 9.05(b), in
determining whether any rights, options or warrants entitle holders of the Common Stock to subscribe for, or purchase, shares of
Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive
Trading Day period ending on the Trading Day immediately preceding the date of announcement for an issuance, and in determining
the aggregate offering price of such shares of Common Stock, there will be taken into account any consideration received by the
Company for such rights, options or warrants and any amount payable on exercise thereof, the value of such consideration, if other
than cash, to be determined by the Board of Directors.


 






    	44



    	 



    

 


(c) Spin-Offs and Other Distributed Property.


 


(i) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the
Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all
holders of the Common Stock, excluding:


 


(A) dividends, distributions, rights, options or warrants as to which an adjustment was effected pursuant to Section 9.05(a)
hereof or Section 9.05(b) hereof, as applicable;


 


(B) dividends or distributions paid exclusively in cash;


 


(C) distributions of Reference Property in a transaction described in Section 9.08(a); and


 


(D) Spin-Offs for which the provisions set forth in Section 9.05(c)(ii) hereof will apply,


 


then the Conversion Rate will be increased based on the following
formula:


 





 


Where:


 





	CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
	 	 	 
	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 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 Company’s Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets, property of the Company, or rights, options or warrants to acquire the Company’s Capital Stock or other securities distributed with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution.







 






    	45



    	 



    

 


Notwithstanding the foregoing, if “FMV”
(as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, each
Holder will receive, for each $1,000 principal amount of Notes held on the Record Date for the distribution, at the same time and
upon the same terms as holders of the Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness,
assets, property of the Company, or rights, options or warrants to acquire Capital Stock or other securities that such Holder would
have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record
Date for such distribution.


 


Any foregoing increase made under the portion
of this clause (c) above will 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 will be decreased to be the Conversion Rate that would then be
in effect if such distribution had not been declared.


 


(ii) With respect to an adjustment pursuant to this Section 9.05(c) where there has been a payment of a dividend or other distribution
on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary
or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed
or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), the
Conversion Rate will be increased based on the following formula:


 








  


Where:


 





	CR0	= 	the Conversion Rate in effect immediately prior to the Close of Business on the last Trading Day of the Valuation Period for such Spin-Off;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Valuation Period for such Spin-Off; 
	 	 	 
	FMV0	= 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period after, and including, the Effective Date of the Spin-Off (the “Valuation Period”); and
	 	 	 
	MP0	= 	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.  







 


If, however, the Conversion Date for a Note
occurs after the Record Date for a Spin-Off, but on or prior to the first Trading Day of the Valuation Period for such Spin-off,
the Conversion Date will be postponed until the Business Day immediately following such Trading Day (and the definition of “FMV0”
will be modified pursuant to the immediately following proviso); and provided, further, that if the Conversion Date
for a Note occurs after the first Trading Day of the Valuation Period for a Spin-Off, but during the Valuation Period, the reference
in the above definition of “FMV0” to “10” will be deemed replaced with such lesser number of
Trading Days as have elapsed from, and including, the Effective Date of such Spin-Off to, but excluding, such Conversion Date.


 






    	46



    	 



    

 


(d) Tender Offers or Exchange Offers. If the Company or any of the Subsidiaries makes a payment in respect of a tender
offer or exchange offer for the Common Stock (other than an odd lot tender offer), to the extent that the cash and value of any
other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of the Common Stock
on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange
offer (such last date, the “Expiration Date”), the Conversion Rate will be increased based on the following
formula:


 








  


Where:


 





	CR0	=	the Conversion Rate in effect immediately prior to the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date;
	 	 	 
	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 purchased in such tender offer or exchange offer; 
	 	 	 
	OS0	= 	the number of shares of Common Stock outstanding immediately prior to the expiration time on the Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);
	 	 	 
	OS1	=	the number of shares of Common Stock outstanding immediately after the expiration time on the Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer); and
	 	 	 
	SP1	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the Expiration Date.  







 






    	47



    	 



    

 


Any increase made under this clause (d)
will become effective immediately after the Close of Business on the 10th Trading Day immediately following, and including, the
Trading Day next succeeding the Expiration Date. If, however, the Conversion Date for a Note occurs on or after the Expiration
Date and on or prior to the Trading Day next succeeding the Expiration Date, the Conversion Date for such Note will be postponed
until the first Business Day immediately following such Trading Day (and the reference in the above definition of “SP1”
to “10” and the references in the above definitions of “CR0” and “CR1”
to “10th” will be modified pursuant to the immediately following proviso); provided, further, that if
the Conversion Date for a Note occurs after the first Trading Day during the 10 Trading Days immediately following, and including,
the Trading Day next succeeding the Expiration Date, but on or prior to the last Trading Day of such period, the reference in the
above definition of “SP1” to “10” and the references in the above definitions of “CR0”
and “CR1” to “10th” shall be deemed replaced with references to such lesser number of Trading
Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding such Conversion
Date.


 


(e) Notwithstanding the foregoing, in any case in which the foregoing subsections (a) through (d) of this Section 9.05 require
that an adjustment be made to the Conversion Rate, in lieu of the adjustment, the Company may, at its option, distribute to Holders
of Notes, concurrently with the distribution to the Holders of the Common Stock (and without having to convert), such shares of
the Common Stock, rights, options, warrants, any shares of the Capital Stock (other than Common Stock), evidences of indebtedness
or other non-cash assets (or the fair market value, as reasonably determined by the Board of Directors, of the foregoing in cash)
that such Holders of Notes would have been entitled to receive had such Notes been converted immediately prior to the Record Date
relating to the event that would have caused such adjustment.


 


(f) Successive Adjustments. After an adjustment to the Conversion Rate under this Article 9, any subsequent event requiring
an adjustment under this Article 9 will cause an adjustment to the Conversion Rate as so adjusted, without duplication.


 


(g) Shareholder Rights Plans. To the extent that the Company has a rights plan in effect when a Holder converts a Note,
the Company will deliver to such Holder, in addition to each share of Common Stock otherwise issuable to such Holder upon conversion
of such Note, any rights that, under the rights plan, would be applicable to a share of Common Stock, unless prior to the Conversion
Date for such Note, the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate
will be adjusted pursuant to Section 9.05(c)(i) as if, at the time of such separation, the Company had distributed to all Holders
of the Common Stock shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,
options or warrants to acquire the Company’s Capital Stock or other securities as described in Section 9.05(c)(i), subject
to readjustment in the event of the expiration or termination of such rights.


 


(h) Other Adjustments. Whenever any provision of this Supplemental Indenture requires the calculation of the Last Reported
Sale Price or a function thereof over a span of multiple days, the Company will make appropriate adjustments to the Last Reported
Sale Price or such function thereof 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, Effective Date or expiration date of the event occurs at any time
during the period when the Last Reported Sale Prices or functions thereof are to be calculated. In addition, if the Ex-Dividend
Date or the expiration date for any event requiring an adjustment to the Conversion Rate occurs before the date on which the Last
Reported Sale Price or function thereof is to be calculated, but the event does not give rise to an adjustment to the Conversion
Rate until after such date, the Company will make an appropriate adjustment to the relevant calculation to account for such event.


 






    	48



    	 



    

 


(i) Restrictions on Adjustments. Except as provided in this Section 9.05, the Company will not adjust the Conversion
Rate for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common
Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. Without limiting the
foregoing, the Conversion Rate will not be adjusted:


 


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


 


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


 


(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in the preceding clause and outstanding as of the Issue Date;


 


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


 


(v) for accrued and unpaid interest (including any applicable Dividend Pass-Through Payment).


 


(j) Deferral of Adjustments. Adjustments to the applicable Conversion Rate will be calculated to the nearest 1/10,000th
of a share, with five one-hundred-thousandths rounded upward (e.g., 0.76545 would be rounded up to 0.7655).


 


(k) Calculation of Adjustments. No adjustment to the Conversion Rate will be required unless the adjustment would require
an increase or decrease of at least 1% of the Conversion Rate; provided, however, that if an adjustment is not made
because the adjustment does not change the Conversion Rate by at least 1%, then such adjustment will be carried forward and taken
into account in any future adjustment. Notwithstanding the foregoing, (i) upon any conversion of the Notes and (ii) annually, on
the anniversary of the original Issue Date, the Company will give effect to all adjustments that it has otherwise deferred pursuant
to the immediately preceding sentence, and those adjustments will no longer be carried forward and taken into account in any future
adjustment.


 






    	49



    	 



    

 


(l) Certain Definitions.


 


(A) For purposes of this Section 9.05, the term “Effective Date” will mean the first date on which the shares
of the Common Stock trade on the applicable exchange or in the applicable market, regular way, reflecting the relevant share split
or share combination, as applicable.


 


(B) For purposes of this Section 9.05, the term “Ex-Dividend Date” will mean the first date on which the
shares of the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive
the issuance, dividend or distribution in question.


 


(C) For purposes of this Section 9.05, the term “Record Date” means, with respect to any dividend, distribution
or other transaction or event in which the holders of the Common Stock have the right to receive any cash, securities or other
property or in which Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities
or other property, the date fixed for determination of holders of the Common Stock entitled to receive such cash, securities or
other property (whether such date is fixed by the Board of Directors, statute, contract or otherwise).


 


Section
9.06 Voluntary Adjustments.


 


(a) Best Interest Increases. Subject to the limitations of Section 9.06(d) hereof, the Company may, from time to time,
to the extent permitted by law, increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase
is in the best interest of the Company, (ii) such increase is in effect for a period of at least 20 Business Days, and (iii) during
such period, such increase is irrevocable.


 


(b) Tax-Related Increases. Subject to the limitations of Section 9.06(d) hereof and to the extent permitted by law, the
Company may (but is not required to) increase the Conversion Rate to avoid, or diminish, any income tax imposed on holders of the
Common Stock or rights to purchase shares of the Common Stock as a result of any dividend or distribution of shares (or rights
to acquire shares) or similar event treated as such for U.S. federal income tax purposes.


 


(c) Notices. Whenever the Board of Directors determines that the Company will increase the Conversion Rate pursuant to
this Section 9.06, the Company will deliver to the Trustee and each Holder written notice of such increase at least 15 Business
Days before such increase will take effect.


 


(d) Voluntary Actions. The Company will not take any voluntary action that would result in an adjustment to the Conversion
Rate pursuant to Sections 9.05, 9.06 and 9.07 without complying, if applicable, with the stockholder approval rules of The New
York Stock Exchange or any similar rule of any stock exchange on which the Common Stock is listed at the relevant time. In accordance
with such listing standards, this restriction will apply at any time when the Notes are outstanding, regardless of whether the
Company then has a class of securities listed on The New York Stock Exchange.

Section
9.07 Adjustments
upon Certain Fundamental Changes.


 


(a) General. If a Fundamental Change (determined after giving effect to the paragraph immediately following clause (iv)
of the definition thereof, but without regard to the exclusion in clause (ii) of the definition thereof) occurs (a “Make-Whole
Fundamental Change”), and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change,
the Company will, in the circumstances described in this Section 9.07, increase the Conversion Rate for such Notes by the number
of additional shares of Common Stock (the “Additional Shares”) described in this Section 9.07. For purposes
of this Section 9.07, a conversion of Notes will be deemed to be “in connection with” a Make-Whole Fundamental Change
if the Conversion Notice for such Notes is received by the Conversion Agent during the period beginning on, and including, the
Make-Whole Fundamental Change Effective Date and ending on, and including, (A) if such Make-Whole Fundamental Change is also a
Fundamental Change, the later of (x) the Close of Business on the Business Day immediately prior to the related Fundamental Change
Repurchase Date and (y) the Close of Business on the 35th Business Day immediately following the date the Company delivers notice
to each Holder of such Make-Whole Fundamental Change pursuant to this Section 9.07, and (B) if such Make-Whole Fundamental Change
is not a Fundamental Change, the Close of Business on the 35th Business Day immediately following the date the Company delivers
notice to each Holder of such Make-Whole Fundamental Change pursuant to this Section 9.07.


 


The Company will notify Holders of the anticipated
effective date of any Make-Whole Fundamental Change and issue a press release announcing such anticipated effective date no later
than 10 Business Days immediately prior to such anticipated effective date; provided, however, that if the Company
does not have knowledge of such Make-Whole Fundamental Change or its anticipated effective date at such time, the Company will
issue such press release as promptly as practicable following the date on which the Company becomes aware of such Make-Whole Fundamental
Change and its anticipated effective date, but in no event later than 5 Business Days immediately following the actual effective
date of such Make-Whole Fundamental Change.


 


(b) Determination of Additional Shares. The number of Additional Shares by which the Conversion Rate will be increased
if a Holder converts a Note in connection with a Make-Whole Fundamental Change will be determined by reference to the table below,
and will be based on the Make-Whole Fundamental Change Effective Date and the Stock Price paid (or deemed paid) per share of our
Common Stock in the Make-Whole Fundamental Change. For any Make-Whole Fundamental Change, the “Make-Whole Fundamental
Change Effective Date” will mean the effective date of such Make-Whole Fundamental Change.


 


(c) Adjustment of Stock Prices and Additional Shares. The Stock Prices set forth in the first row (i.e., the column headers)
of the table below will be adjusted on each date on which the Conversion Rate must be adjusted pursuant to Section 9.05. The adjusted
Stock Prices will equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, (i) the numerator
of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment, and (ii)
the denominator of which is the Conversion Rate in effect immediately after the adjustment. The numbers of Additional Shares set
forth in the table below will be adjusted in the same manner, at the same time and for the same events for which the Conversion
Rate is adjusted pursuant to Section 9.05 hereof.

(d) Additional Shares Table. The following table sets forth the number of Additional Shares by which the Conversion Rate
will be increased per $1,000 principal amount of Notes for a Holder that converts a Note in connection with a Make-Whole Fundamental
Change having such Make-Whole Fundamental Change Effective Date and Stock Price.

(e) Use of Additional Shares Table. If the Stock Price and/or Make-Whole Fundamental Change Effective Date for a Make-Whole
Fundamental Change are not set forth in the table above, then:


 


		(1)	if the Stock Price is between two Stock Prices in the table or the Make-Whole Fundamental Change Effective Date is between
two Make-Whole Fundamental Change Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will
be increased for a Holder that converts a Note in connection with such Make-Whole Fundamental Change will be determined by a straight-line
interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices listed in the table and the
earlier and later Make-Whole Fundamental Change Effective Dates listed in the table, as applicable, based on a 365-day year;



 


		(2)	if the Stock Price is greater than $56.00, subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table, no Additional Shares will be added to the Conversion Rate; and



 


		(3)	if the Stock Price is less than $21.73, subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table, no Additional Shares will be added to the Conversion Rate.



 


Notwithstanding the foregoing, in no event will the Conversion
Rate be increased as a result of this Section 9.07 to exceed 46.0193 shares of Common Stock per $1,000 principal amount of Notes,
subject to adjustment in the same manner, at the same time and for the same events for which the Conversion Rate must be adjusted
as set forth in Section 9.05 hereof.


 






    	52



    	 



    

 


(f) Settlement or Conversion. Except as provided in Section 9.08 hereof, if a Holder converts a Note in connection with
a Make-Whole Fundamental Change, the Company will settle such conversion by delivering, on the third Business Day immediately following
the Conversion Date for such Note, a number of shares of Common Stock and an amount of cash in lieu of fractional shares of Common
Stock in accordance with Section 9.03 hereof; provided, however, that notwithstanding anything to the contrary in
Section 9.03 hereof, if a Holder converts a Note in connection with a Make-Whole Fundamental Change described in clause (ii) of
the definition of Fundamental Change in which the holders of the Common Stock receive only cash in consideration for their shares
of Common Stock, the Company will settle such conversion by delivering to such Holder, on the third Business Day immediately following
the Conversion Date for such Note, an amount of cash, for each $1,000 principal amount of such Note converted, equal to the product
of (i) the Conversion Rate on the Conversion Date applicable to such Note (including any Additional Shares added to such Conversion
Rate pursuant to this Section 9.07) and (ii) the Stock Price for such Make-Whole Fundamental Change.


 


Section
9.08 Effect of Recapitalization,
Reclassification, Consolidation, Merger or Sale.


 


(a) General. If any of the following events occur:


 


		(1)	any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination
or change only in par value or from par value to no par value or no par value to par value);



 


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



 


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



 


		(4)	any statutory share exchange;



 


in each case, as a result of which the Common Stock would be
converted into, or exchanged for, Capital Stock, other securities, other property or assets (including cash or any combination
thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the
right to convert each $1,000 principal amount of Notes into shares of Common Stock and cash in lieu of fractional shares of Common
Stock will be changed into the right to convert each $1,000 principal amount of Notes into the kind and amount of shares of stock,
other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of
Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive in
exchange for its shares of Common Stock upon such Merger Event (the “Reference Property”, together with an amount
of cash in lieu of any fractional units of Reference Property based on the value of a Unit of Reference Property). Prior to or
at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute
with the Trustee a supplemental indenture pursuant to Section 8.03 hereof providing for such change in the right to convert each
$1,000 principal amount of Notes.


 






    	53



    	 



    

 


If the Merger Event causes the Common Stock to be converted
into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of
shareholder election), then the Reference Property into which the Notes will be convertible shall be deemed to be the weighted
average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election.
The Company shall notify Holders of such weighted average as soon as practicable after such determination is made.


 


As promptly as practicable after executing a supplemental indenture
in accordance with Section 9.08(a) hereof, the Company will (i) file with the Trustee an Officer’s Certificate briefly describing
the reasons therefor, the composition of a Unit of Reference Property for such Merger Event, any adjustment to be made with respect
thereto and that all conditions precedent under the Indenture to such Merger Event have been complied with; and (ii) cause to be
sent to each Holder, at the address of such Holder as it appears in the register of the Notes maintained by the Registrar, a notice
of the execution of such supplemental indenture and the composition of a Unit of Reference Property for such Merger Event; provided
that the failure to deliver such notice to any Holder will not affect the validity or legality of such supplemental indenture.


 


(b) Successive Merger Events. If more than one Merger Event occurs, this Section 9.08 will apply successively to each
Merger Event.


 


(c) Compliance Covenant. The Company will not become a party to any Merger Event unless its terms are consistent with
this Section 9.08.


 


Section
9.09 Notice to Holders
Prior to Certain Actions.


 


(a) In case of any Merger Event then the Company shall cause to be filed with the Trustee and the Conversion Agent (if other
than the Trustee) and to be sent to each Holder at its address appearing on the Register, as promptly as possible but in any event
at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken
for the purpose of such action by the Company or one of the Subsidiaries or, if a record is not to be taken, the date as of which
the holders of Common Stock of record are to be determined for the purposes of such action by the Issuer or one of the Subsidiaries,
(ii) the date on which such Merger Event is expected to become effective or occur, (iii) the Conversion Rate in effect as of the
date the Company delivers such notice, (iv) the composition of a Unit of Reference Property for such Merger Event and (v) if applicable,
the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such Merger Event. Failure to give such notice, or any defect therein, shall not
affect the legality or validity of such action by the Company or one of the Subsidiaries.


 


(b) Whenever the Company adjusts the Conversion Rate pursuant to Section 9.05 (other than the issuance of dividends in the form
of Common Stock), the Company will promptly deliver to each Holder a written notice, which notice will include (i) a brief description
of the event requiring adjustment to the Conversion Rate pursuant to Section 9.05, (ii) the effective date of such adjustment,
(iii) the Conversion Rate in effect after such adjustment is made and (iv) and the manner of computing such adjustment. On the
same day the Company delivers such notice to each Holder, the Company will deliver to the Trustee, the Paying Agent and the Conversion
Agent an Officer’s Certificate that includes all of the information contained in such notice, which Officer’s Certificate
each of the Trustee, the Paying Agent and the Conversion Agent may treat as conclusive evidence that the adjustment specified in
such Officer’s Certificate is correct and will be in effect as of the effective date specified in such Officer’s Certificate.
The failure to deliver such notice will not affect the legality or validity of any such adjustment.


 






    	54



    	 



    

 


Section 9.10 No Responsibility of Trustee. The Trustee
and the Conversion Agent will not have any duty or responsibility to any Holder to determine whether any facts exist that require
an adjustment 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 in making the same. Neither the Trustee nor the Conversion Agent will be responsible for
any failure of the Company to deliver the number of shares of Common Stock and any amount of cash in lieu of fractional shares
of Common Stock due upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities
or covenants of the Company contained in this Article 9. Without limiting the generality of the foregoing, neither the Trustee
nor the Conversion Agent will be under any responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 9.08 hereof, including with respect to the calculation of the amount of cash and the
number of Units of Reference Property, if any, receivable by Holders upon the conversion of their Notes after any Merger Event,
and each, subject to the provisions of Article 6, may accept as conclusive evidence of the correctness of any such provisions,
and will be protected in relying upon, the Officer’s Certificate (which the Company will be obligated to file with the Trustee
prior to the execution of any such supplemental indenture) with respect thereto.


 







Article
10

MISCELLANEOUS


 


Article 10 (Miscellaneous) of the Base Indenture
is hereby supplemented, with respect to the Notes, to add the following:


 





Section 10.01 No Personal Liability of
Shareholders, Employees, Officers or Directors. None of the Company’s, or of any successor entity’s, direct or
indirect shareholders, employees, officers or directors, as such, past, present or future, shall have any personal liability in
respect of the Company’s obligations under the Indenture of the Notes solely by reason of his, her or its status as such
shareholder, employee, officer or director.


 


Section 10.02 Calculations. Except
as otherwise provided in this Supplemental Indenture, the Company or our agents will be responsible for making all calculations
called for under the Notes and this Supplemental Indenture. These calculations include, but are not limited to, determinations
of the Last Reported Sale Price of the Common Stock or any other security, accrued interest (including any applicable Dividend
Pass-Through Payment) payable on the Notes and the Conversion Rate in effect on any Conversion Date. Neither the Trustee nor the
Conversion Agent will be responsible for making any such calculations.


 






    	55



    	 



    

 







The Company or its agents will make these
calculations in good faith and, absent manifest error, its calculations will be final and binding on all Holders. The Company or
its agents will provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee
and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent
verification. If any Holder requests from the Trustee a copy of such schedule, the Trustee will promptly forward a copy of such
schedule to such Holder.


 





Section 10.03 Legal Holidays. If the Maturity Date or
any Interest Payment Date, Fundamental Change Repurchase Date, or Conversion Date is not a Business Day, then any action to be
taken on such date need not be taken on such date, but may be taken on the immediately following Business Day with the same force
and effect as if taken on such date, and no interest will accrue (and no additional Dividend Pass-Through Payment will be made)
for the period from and after such date.

[FORM OF REVERSE OF NOTE]


 


VECTOR GROUP LTD.


 


Variable Interest Convertible Senior Notes
due 2020


 


This Note is one of a duly authorized issue
of notes of Vector Group Ltd. (the “Company”), designated as its Variable Interest Convertible Senior Notes
due 2020 (the “Notes”), all issued or to be issued under and pursuant to an indenture dated as of November 20,
2012 (the “Base Indenture”), between the Company and Wells Fargo Bank, National Association (the “Trustee”),
as supplemented by the Second Supplemental Indenture, dated as of the Issue Date (the “Supplemental Indenture”
and the Base Indenture as supplemented by the Supplemental Indenture, the “Indenture”), between the Company
and 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. Capitalized terms
used herein and not defined herein have the meanings ascribed to them in the Indenture, and the terms of the Notes include those
stated in the Indenture and those incorporated into the Indenture.


 


1. Interest.


 


This Note will bear cash interest at a rate
of 1.75% per annum (the “Fixed Interest”), with an additional cash payment payable on the Notes on each Interest
Payment Date equal to the product of (A) the amount of cash dividends per share actually paid by the Company on the outstanding
Common Stock during the prior three-month period ending on the Record Date for such interest payment and (B) the applicable conversion
rate on such Record Date (the “Dividend Pass-Through Payment,” together with the Fixed Interest, the “Total
Interest”). Notwithstanding the foregoing, however, (A) the amount payable on each Interest Payment Date, other than
the initial Interest Payment Date, will be the higher of (i) the Total Interest and (ii) 5.50% per annum (the “Floor Interest
Rate”) and (B) the initial Interest Payment Date will be based solely on the Floor Interest Rate. The Fixed Interest
or the Floor Interest Rate, as applicable, on this Note will accrue from the Issue Date or from the most recent date to which interest
has been paid or provided for. Each payment of the Fixed Interest or the Floor Interest Rate, as applicable, on this Note will
include interest accrued for the period commencing on and including the immediately preceding Interest Payment Date (or, if none,
the Issue Date) through the day before the applicable Interest Payment Date.


 


In addition, if the Notes would otherwise
constitute “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Internal Revenue
Code of 1986, as amended, on each Interest Payment Date on or after April 15, 2019, the Company will pay additional interest on
a Note in an amount equal to the amount required to be paid to prevent such Note from being treated as an applicable high yield
discount obligation.


 


Payments of the Fundamental Change Repurchase
Price, principal and interest (including any Dividend Pass-Through Payment, if applicable) that are not made when due will accrue
interest at an annual rate equal to the then-applicable interest rate plus one percent from the applicable payment date.


 






    	1



    	 



    

 


Pursuant to Section 6.04 of the Indenture,
in certain circumstances, the Company will pay Special Interest on this Note.


 


2. Method of Payment.


 


The Company will promptly make all payments
on this Note on the dates and in the manner provided herein and in the Indenture. Payments on Notes represented by a Global Note
(including principal and interest (including any Dividend Pass-Through Payment, if applicable)) will be made by wire transfer of
immediately available funds to the accounts specified by Depositary. The Company will pay principal of, and any Fundamental Change
Repurchase Price for, Definitive Notes at the office or agency designated by the Company for such purpose. Interest (including
any Dividend Pass-Through Payment) on Definitive Notes will be made by check or by wire transfer, as described in Section 2.04,
except that any payment of interest due on the Maturity Date will be made at the office or agency designated by the Company for
such purpose. All payments on this Note will be made in money of the United States that at the time of payment is legal tender
for payment of public and private debts.


 


3. Paying Agent, Conversion Agent and Registrar.


 


Initially, Wells Fargo Bank, National Association
will act as the Trustee, Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion
Agent or Registrar; provided that the Company will maintain at least one Paying Agent, Conversion Agent and Registrar in
the continental United States. The Company or any of the Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion
Agent or Registrar.


 


4. Repurchase By the Company at the Option of the Holder upon a Fundamental Change.


 


At the option of the Holder, and subject
to the terms and conditions of the Indenture, upon the occurrence of a Fundamental Change, each Holder will have the right, at
its option, to require the Company to repurchase for cash all of its Notes, or any portion of its Notes having a principal amount
equal to $1,000 or an integral multiple of $1,000 in excess thereof, at a Fundamental Change Repurchase Price equal to 100% of
the principal amount of Notes to be purchased plus accrued and unpaid interest (calculated at the greater of the Total Interest
(with the Fundamental Change Repurchase Date treated as an Interest Payment Date for purposes of calculating the Dividend Pass-Through
Payment payable as a component thereof and such Dividend Pass-Through Payment will be calculated based on the amount of cash dividends
per share actually paid by the Company on the outstanding Common Stock during the period commencing on the most recent prior Record
Date and ending on the Fundamental Change Repurchase Date and will be pro rated by multiplying the amount otherwise payable by
a fraction, the numerator of which is the number of days during the period from and including the most recent prior Record Date
to, but excluding, the Fundamental Change Repurchase Date and the denominator of which is 90) and the Floor Interest Rate) to,
but excluding, the Fundamental Change Repurchase Date, unless the Fundamental Change Repurchase Date occurs after a Regular Record
Date and on or before the Interest Payment Date corresponding to such Regular Record Date, in which case such accrued and unpaid
interest, if any, on the Notes will be paid to the Holders of such Notes as of the Close of Business on such Regular Record Date
and the Fundamental Change Repurchase Price will equal 100% of the principal amount of such Notes. To exercise its purchase right,
a Holder must comply with the procedures set forth in Article 3 of the Supplemental Indenture.


 






    	2



    	 



    

 


5. No Redemption at the Option of the Company.


 


The Company may not redeem the Notes prior
to the Maturity Date. The Notes are not subject to redemption through the operation of any sinking fund or otherwise.


 


6. Conversion.


 


Subject to, or upon, compliance with the
provisions set forth in the Indenture, a Holder of this Note has the right, at such Holder’s option, to convert the principal
amount hereof or any portion of such principal amount that is equal to $1,000 or an integral multiple of $1,000 in excess thereof,
into (i) a number of shares of Common Stock equal to the product of (A) the Conversion Rate in effect on the applicable Conversion
Date and (B) the principal amount of Notes converted divided by $1,000, rounded down to the nearest whole number, and (ii)
an amount of cash equal to the product of (A) the fraction of a share of Common Stock eliminated by such rounding and (B) the Last
Reported Sale Price of the Common Stock on such Conversion Date.


 


7. Denominations; Transfer; Exchange.


 


The Notes are in fully registered form,
without coupons, in denominations of $1,000 of principal amount and integral multiples of $1,000 in excess thereof. A Holder may
transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.


 


8. Amendment, Supplement and Waiver.


 


Subject to certain exceptions, the Indenture
permits the Indenture and the Notes to be amended or supplemented with the written consent of the Holders of at least a majority
in aggregate principal amount of the then outstanding Notes. In certain circumstances, the Company and the Trustee may also amend
or supplement the Indenture or the Notes without the consent of any Holder. Subject to certain exceptions, the Indenture permits
the waiver of certain Events of Default or the noncompliance with certain provisions of the Indenture and of the Notes with the
written consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes.


 


9. Defaults and Remedies.


 


Subject to the following paragraph, if an
Event of Default specified in the Indenture occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount
of the Notes then outstanding may declare all the Notes to be due and payable immediately by delivering notice to the Company.
In addition, certain specified Events of Default will cause the Notes to become immediately due and payable without the Holders
taking any action.


 






    	3



    	 



    

 


If the Company so elects, the sole remedy
for an Event of Default relating to the Company’s failure to comply with the reporting obligations under Section 4.02 of
the Indenture will, for the 365 days after the occurrence of such Event of Default, consist exclusively of the right to receive
Special Interest on the principal amount of the Notes.


 


Holders may not enforce the Indenture or
the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives
indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority of the principal amount of the
then outstanding Notes may direct the Trustee in its exercise of any trust or power. Subject to certain exceptions, the Trustee
may withhold from Holders notice of any continuing Event of Default or Default (except in payment on any Notes or the failure to
convert Notes in accordance with the Indenture) if it determines in good faith that withholding notice is in their interest.


 


10. Persons Deemed Owners.


 


The Holder of this Note will be treated
as the owner of this Note for all purposes.


 


11. Unclaimed Money or Notes.


 


The Trustee and the Paying Agent will return
to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Notes
that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled
to the money or securities must look to the Company for payment as general creditors, unless an applicable abandoned property law
designates another person.


 


12. Trustee Dealings with the Company.


 


The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company
or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not the
Trustee.


 


13. Calculations in Respect of Notes.


 


Except as otherwise provided in the Indenture,
the Company or its agents will be responsible for making all calculations called for under the Notes and the Indenture. These calculations
include, but are not limited to, determinations of the Last Reported Sale Price of the Common Stock or any other security, accrued
interest (including any applicable Dividend Pass-Through Payment) payable on the Notes and the Conversion Rate in effect on any
Conversion Date.


 


The Company will make all these calculations
in good faith and, absent manifest error, its calculations will be final and binding on all Holders.


 






    	4



    	 



    

 


14. No Recourse Against Others.


 


A director, officer, employee or stockholder,
as such, of the Company will not have any liability for any obligations of the Company under the Notes or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and
releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.


 


15. Authentication.


 


This Note will not be valid until an authorized
