The
Securities

 

Section 2.01. Form
and Dating. The Securities and the Trustee’s certificate of authentication shall be substantially in the form set forth
in Exhibit A, which is incorporated in and forms a part of this Indenture. The Securities may have notations, legends or endorsements
required by law, stock exchange rule or usage; provided that such notations, legends or endorsements are in a form reasonably
acceptable to the Company. Each Security shall be dated the date of its authentication.

 

The Securities shall
be issued initially in the form of one or more global securities, substantially in the form set forth in Exhibit A (each Security
in such form, a “Global Security”), deposited with the Trustee, as custodian for the Depositary, registered
in the name of the Depositary or a nominee thereof, duly executed by the Company and authenticated by the Trustee as hereinafter
provided and bearing the legends set forth in Exhibits B-1A and B-2. The aggregate principal amount of each Global Security may
from time to time be increased or decreased by adjustments made on the records of the Trustee, upon the occurrence of which the
Trustee shall make a corresponding adjustment on the “Schedule of Exchanges of Interests in the Global Security” attached
thereto, as hereinafter provided.

 

Securities issued in
exchange for interests in a Global Security pursuant to Section 2.15 may be issued in the form of permanent certificated Securities
in registered form in substantially the form set forth in Exhibit A (each, a “Physical Security”) and, if applicable,
bearing any legends required by Section 2.17.

 

Section 2.02. Execution
and Authentication. One duly authorized Officer shall sign the Securities for the Company by manual or facsimile signature.

 

A Security’s
validity shall not be affected by the failure of an Officer whose signature is on such Security to hold, at the time the Security
is authenticated, the same office at the Company.

 

A Security shall not
be valid until duly authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Security
has been authenticated under this Indenture.

 

Upon a Company Order,
the Trustee shall authenticate Securities for original issue in the aggregate principal amount of $172,500,000. The aggregate principal
amount of Securities outstanding at any time may not exceed $172,500,000, subject to the immediately succeeding paragraph and except
for Securities authenticated and delivered in lieu of lost, destroyed or wrongfully taken Securities pursuant to Section 2.07.

 

The Company may, without
the consent of Holders of the Securities, increase the aggregate principal amount of Securities by issuing additional Securities,
(“Additional Securities”) in the future with the same CUSIP number and on the same terms and conditions as the
Securities initially issued hereunder, except for any difference in the issue price and interest accrued prior to the issue date
of the Additional Securities; provided that if any such Additional Securities are not fungible with the Securities initially
issued hereunder for United States federal income tax purposes, such Additional Securities shall have a separate CUSIP number.
The Securities initially issued hereunder and any such Additional Securities shall rank equally and ratably and shall be treated
as a single series of debt securities for all purposes under this Indenture.

 

    	-8-

    	 

    

 

Upon a Company Order,
the Trustee shall authenticate Securities, including Securities not bearing the Security Private Placement Legend, to be issued
to the transferees when sold pursuant to an effective registration statement under the Securities Act as set forth in Section 2.16(b)
or when not otherwise required under this Indenture to bear the Security Private Placement Legend.

 

The Trustee shall act
as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture
to authentication by the Trustee includes authentication by such authenticating agent. An authenticating agent so appointed has
the same rights as a Securities Agent to deal with the Company and its Affiliates.

 

The Securities shall
be issuable only in registered form without interest coupons and only in denominations of $1,000 principal amount and any integral
multiple thereof.

 

Section 2.03. Registrar,
Paying Agent and Conversion Agent. The Company shall maintain, or shall cause to be maintained, (i) an office or agency in
The Borough of Manhattan, The City of New York, where Securities may be presented for registration of transfer or for exchange
(“Registrar”), (ii) an office or agency in The Borough of Manhattan, The City of New York, where Securities
may be presented for payment (“Paying Agent”) and (iii) an office or agency in the Borough of Manhattan, The
City of New York, where Securities may be presented for conversion (“Conversion Agent”). The Registrar shall
keep a register of the Securities and of their transfer and exchange. The Company may appoint or change one or more co-registrars,
one or more additional paying agents and one or more additional conversion agents without notice and may act in any such capacity
on its own behalf. The term “Registrar” includes any co-registrar; the term “Paying Agent”
includes any additional paying agent; and the term “Conversion Agent” includes any additional conversion agent.

 

The Company shall enter
into an appropriate agency agreement with any Securities Agent not a party to this Indenture. Such agency agreement shall implement
the provisions of this Indenture that relate to such Securities Agent. The Company shall notify the Trustee of the name and address
of any Securities Agent not a party to this Indenture. The Company may change any Securities Agent without notice to any Holder.
If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such.

 

The Company initially
appoints the Trustee as Paying Agent, Registrar and Conversion Agent.

Section 2.04. Paying
Agent to Hold Money in Trust. Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all moneys
held by the Paying Agent for the payment of the Securities, and shall notify the Trustee of any Default by the Company in making
any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee.
The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds so paid
by it. Upon payment over to the Trustee, the Paying Agent shall have no further liability for such money. If the Company acts as
Paying Agent, it shall segregate and hold as a separate trust fund all money held by it as Paying Agent.

 

Section 2.05. Holder
Lists. The Trustee shall 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, or shall cause to be furnished,
to the Trustee before each Interest Payment 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 appearing in the security
register of the Registrar.

 

Section 2.06. Transfer
and Exchange. Subject to Sections 2.15 and 2.16 hereof, when Securities are presented to the Registrar with a request to register
their transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar
shall register the transfer or make the exchange if its requirements for such transaction are met. To permit registrations of transfer
and exchanges, the Trustee shall authenticate Securities at the Registrar’s request or upon the Trustee’s receipt of
a Company Order therefor. The Company, the Registrar or the Trustee, as the case may be, shall not be required to register the
transfer of or exchange any Security for which a Repurchase Notice has been delivered, and not withdrawn, in accordance with this
Indenture, except if the Company has defaulted in the payment of the Fundamental Change Repurchase Price with respect to such Security
or to the extent that a portion of such Security is not subject to such Repurchase Notice.

 

No service charge shall
be made for any transfer, exchange or conversion of Securities, but the Company may require payment of a sum sufficient to cover
any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of
Securities, other than exchanges pursuant to Sections 2.07, 2.10, 3.02, 9.04 or 10.02, in each case, not involving any transfer.

 

Section 2.07. Replacement
Securities. If the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the
Company shall issue and the Trustee shall authenticate, at the Holder’s expense, a replacement Security upon surrender to
the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss, destruction or theft of the Security
satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Security, if required by the
Trustee or the Company, indemnity (including in the form of a bond) must be provided by the Holder that is reasonably satisfactory
to the Trustee and the Company to indemnify and hold harmless the Company, the Trustee or any Securities Agent from any loss that
any of them may suffer if such Security is replaced.

 

In case any such mutilated,
lost, destroyed or wrongfully taken Security has become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay the amounts due in respect of such Security as provided hereunder.

 

    	-10-

    	 

    

 

Every replacement Security
is an additional obligation of the Company only as provided in Section 2.08.

 

Section 2.08. Outstanding
Securities. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those converted,
those cancelled by it, those delivered to it for cancellation, those reductions in the amount of a Global Security effected by
the Trustee hereunder, and those described in this Section 2.08 as not outstanding. Except to the extent provided in Section 2.09,
a Security does not cease to be outstanding because the Company or one of its Subsidiaries or Affiliates holds the Security.

 

If a Security is replaced
pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it, or a court holds, that
the replaced Security is held by a protected purchaser.

 

If the Paying Agent
(in the case of a Paying Agent other than the Company) holds on a Fundamental Change Repurchase Date or the Maturity Date, money
sufficient to pay the aggregate Fundamental Change Repurchase Price or principal amount (plus accrued and unpaid interest, if any),
as the case may be, with respect to all Securities to be repurchased or paid on such Fundamental Change Repurchase Date or the
Maturity Date, as the case may be, in each case, payable as herein provided on such Fundamental Change Repurchase Date or the Maturity
Date, then (unless there shall be a Default in the payment of such aggregate Fundamental Change Repurchase Price or principal amount,
or of such accrued and unpaid interest), except as otherwise provided herein, on and after such date such Securities shall be deemed
to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed to be paid
whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall
terminate with respect to such Securities, other than the right to receive the Fundamental Change Repurchase Price or principal
amount, as the case may be, plus, if applicable, such accrued and unpaid interest, in accordance with this Indenture.

 

If a Security is converted
in accordance with Article 10 then, from and after the time of such conversion on the Conversion Date, such Security shall cease
to be outstanding, and interest, if any, shall cease to accrue on such Security unless there shall be a Default in the payment
or delivery of the consideration payable and/or deliverable hereunder upon such conversion (except that any such Security will
remain outstanding for the purpose of receiving any interest or other amounts due following such conversion as set forth in this
Indenture).

 

Section 2.09. Securities
Held by the Company or an Affiliate. In determining whether the Holders of the required aggregate principal amount of Securities
have concurred in any direction, waiver or consent, Securities owned by the Company or any of its Subsidiaries or Affiliates shall
be considered as though not outstanding, except that, for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows are
so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be considered to be outstanding
for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of the Trustee, the pledgee’s right so
to concur with respect to such Securities and that the pledgee is not, and is not acting at the direction or on behalf of, the
Company, any other obligor on the Securities, an Affiliate of the Company or an Affiliate of any such other obligor. In case of
a dispute as to whether the pledgee has established the foregoing, any decision by the Trustee taken upon the advice of counsel
shall provide full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an
Officers’ Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for
the account of any of the above described Persons; and, subject to Section 7.01 and Section 7.02, the Trustee shall be entitled
to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities
not listed therein are outstanding for the purpose of any such determination.

 

    	-11-

    	 

    

 

Section 2.10. Temporary
Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall, upon receipt
of a Company Order therefor, authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive
Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay,
the Company shall prepare and the Trustee, upon receipt of a Company Order therefor, shall authenticate definitive Securities in
exchange for temporary Securities. Until so exchanged, each temporary Security shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities, and such temporary Security shall be exchangeable for definitive Securities in accordance
with the terms of this Indenture.

 

Section 2.11. Cancellation.
The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, Paying Agent and Conversion
Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee
shall promptly cancel all Securities surrendered for transfer, exchange, payment, conversion or cancellation in accordance with
its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee
for cancellation or that any Holder has converted pursuant to Article 10. All cancelled Securities held by the Trustee shall be
disposed of in accordance with its customary procedure for the disposal of cancelled securities, and certification of such disposal
shall be delivered by the Trustee to the Company unless the Company shall, by a Company Order, direct that cancelled Securities
be returned to it.

 

Section 2.12. Defaulted
Amounts. If, and to the extent, the Company defaults in a payment on the Securities (including any payments of the Fundamental
Change Repurchase Price, principal or interest), the Company shall pay interest on such amounts in cash, to the extent not prohibited
by applicable statute or case law, on such defaulted amounts at the then-applicable interest rate provided in the Securities plus
one percent (1%) from the required payment date. The Company may pay the defaulted amounts (plus interest on such defaulted amounts)
to the Persons who are Holders on a subsequent special record date. The Company shall fix such special record date and payment
date. At least fifteen (15) calendar days before the special record date, the Company shall deliver to Holders a notice that states
the special record date, payment date and amount of interest to be paid. Upon the due payment in full, interest shall no longer
accrue on such defaulted interest pursuant to this Section 2.12.

 

    	-12-

    	 

    

 

Section 2.13. Cusip
Numbers. The Company in issuing the Securities may use one or more “CUSIP” numbers, and, if so, the Trustee shall
use the CUSIP numbers in notices as a convenience to Holders; provided, however, that no representation is hereby
deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers printed on the notice or on the Securities;
and provided further that reliance may be placed only on the other identification numbers printed on the Securities,
and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company
shall promptly notify the Trustee of any change in the CUSIP numbers.

 

Section 2.14. Deposit
of Moneys. Prior to 11:00 A.M., New York City time, on each Interest Payment Date, the Maturity Date or any Fundamental Change
Repurchase Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust in accordance with Section 2.04) money, in funds immediately available on such date, sufficient to make cash
payments, if any, due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date, as the case
may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, the Maturity
Date or such Fundamental Change Repurchase Date, as the case may be.

 

If any Interest Payment
Date, the Maturity Date or any Fundamental Change Repurchase Date falls on a date that is not a Business Day, the payment due on
such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date, as the case may be, shall be postponed
until the next succeeding Business Day, and no interest or other amount shall accrue as a result of such postponement.

 

Section 2.15. Book-Entry
Provisions for Global Securities. (a)  Global Securities initially shall (i) be registered in the name of the Depositary,
its successors or their respective nominees, (ii) be delivered to the Trustee as custodian for the Depositary, its successors or
their respective nominees, as the case may be, and (iii) bear the legends such Global Securities are required to bear under Section
2.17.

 

Members of, or participants
in, the Depositary (“Participants”) shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may be
treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for
all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and Participants, the operation of customary practices governing the exercise of the rights
of a Holder of any Security.

 

    	-13-

    	 

    

 

(b)          Transfers
of Global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective
nominees. In addition, one or more Physical Securities shall be transferred to each owner of a beneficial interest in a Global
Security, as identified by the Depositary, in exchange for its beneficial interest in the Global Securities if (i) the Depositary
notifies the Company that the Depositary is unwilling or unable to continue as depositary for any Global Security, or the Depositary
ceases to be a “clearing agency” registered under Section 17A of the Exchange Act, and, in either case, a successor
Depositary is not appointed by the Company within ninety (90) days of such notice or cessation or (ii) an Event of Default has
occurred and is continuing and the Registrar has received a written request from the beneficial owner of the relevant Securities
to issue Physical Securities. For the avoidance of doubt, if any event described in clause (i) of the immediately preceding sentence
occurs, any owner of a beneficial interest in any Global Security will be entitled to receive one or more Physical Securities in
exchange for its beneficial interest or interests in the Global Securities, and if any event described in clause (ii) of the immediately
preceding sentence occurs, only the beneficial owner that has made a written request to the Registrar will be entitled to receive
one or more Physical Securities in exchange for its beneficial interest or interests in the Global Securities. The Company may
also exchange beneficial interests in a Global Security for one or more Physical Securities registered in the name of the owner
of beneficial interests if the Company and the owner of such beneficial interests agree to so exchange.

 

(c)          In
connection with the transfer of a Global Security in its entirety to beneficial owners pursuant to Section 2.15(b), such Global
Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall
upon written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depositary in exchange
for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations.

 

(d)          During
the period of one (1) year after the last date on which any of the Securities are originally issued, any Physical Security delivered
in exchange for an interest in a Global Security pursuant to Section 2.15(b) shall, except as otherwise provided by Section 2.16,
bear the Security Private Placement Legend.

 

(e)          The
Holder of any Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may
hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Securities.

 

(f)          The
Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on the transfer
of any interest in any Securities imposed under this Indenture or under applicable law (including any transfers between or among
Participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and
other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this
Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

 

(g)          Neither
the Trustee nor any Securities Agent shall have any responsibility for any actions taken or not taken by the Depositary.

 

Section 2.16. Special
Transfer Provisions. (a)  Notwithstanding any other provisions of this Indenture, but except as provided in Section
2.15(b), a Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee
of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary.

(b)          Upon
the transfer, exchange or replacement of Securities not bearing the Security Private Placement Legend, unless the Company notifies
the Registrar otherwise, the Registrar shall deliver Securities that do not bear the Security Private Placement Legend. Upon the
transfer, exchange or replacement of Securities bearing the Security Private Placement Legend, the Registrar shall deliver only
Securities that bear the Security Private Placement Legend unless (i) the requested transfer, exchange or replacement is after
the Resale Restriction Termination Date, (ii) there is delivered to the Trustee and the Company an opinion of counsel reasonably
satisfactory to the Company and addressed to the Company to the effect that neither such legend nor the related restrictions on
transfer are required in order to maintain compliance with the provisions of the Securities Act or (iii) such Security has been
sold pursuant to an effective registration statement under the Securities Act and the Holder selling such Securities has delivered
to the Registrar a notice in the form of Exhibit C hereto. Upon any transfer or exchange of a beneficial interest in the Securities
in connection with which the Security Private Placement Legend will be removed in accordance with this Indenture (including, without
limitation, an exchange of a Global Security in whole in accordance with the applicable procedures), the Trustee shall increase
the principal amount of the Global Security that does not constitute a Restricted Security by the principal amount of such transfer
or exchange and likewise reduce the principal amount of the Global Security that does constitute a Restricted Security.

 

(c)          By
its acceptance of any Security or share of Common Stock bearing the Security Private Placement Legend or the Common Stock Private
Placement Legend, each holder thereof acknowledges the restrictions on transfer of such security set forth in this Indenture and
in the Security Private Placement Legend or Common Stock Private Placement Legend, as applicable, and agrees that it will transfer
such security only as provided in this Indenture and as permitted by applicable law.

 

The Registrar shall
retain copies of all letters, notices and other written communications received pursuant to Section 2.15 or this Section 2.16.
The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any
reasonable time upon the giving of reasonable written notice to the Registrar.

 

(d)          Any
Securities that are purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate
unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities
Act in a transaction that results in such Securities no longer being Restricted Securities.

 

(e)          The
Company may, to the extent permitted by law, purchase the Securities in the open market or by tender offer at any price or by private
agreement without giving prior notice to Holders. The Company may, at its option and to the extent permitted by law, reissue, resell
or surrender to the Trustee for cancellation any Securities the Company purchases in this manner, in the case of a re-issuance
or resale, so long as such Securities do not constitute Restricted Securities upon such re-issuance or resale. Securities surrendered
to the Trustee for cancellation may not be reissued or resold and shall be promptly cancelled pursuant to Section 2.11.

 

    	-15-

    	 

    

 

Section 2.17. Restrictive
Legends. Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the “Security
Private Placement Legend”) as set forth in Exhibit B-1A on the face thereof until the later of (i) the date that is one
year after the last date of original issuance of such Securities, or such shorter period of time as permitted by Rule 144 under
the Securities Act or any successor provision thereto, and (ii) such later date, if any, as may be required by applicable law (such
date, the “Resale Restriction Termination Date”). Each certificate representing shares of Common Stock issued
upon conversion of any Security, shall, upon issuance, if such shares constitute Restricted Securities at their time of issuance,
bear the legend (the “Common Stock Private Placement Legend”) as set forth in Exhibit B-1B on the face thereof
until the Resale Restriction Termination Date.

 

Each Global Security
shall also bear the legend as set forth in Exhibit B-2.

 

Article
3

Redemption and Repurchase

 

Section 3.01. No
Redemption. The Securities shall not be redeemable at the option of the Company prior to the Maturity Date, and no sinking
fund is provided for the Securities.

 

Section 3.02. Repurchase
at Option of Holder Upon a Fundamental Change. (a)  If a Fundamental Change occurs, each Holder of Securities shall
have the right (the “Fundamental Change Repurchase Right”), at such Holder’s option, to require the Company
to repurchase (a “Repurchase Upon Fundamental Change”) all of such Holder’s Securities (or portions thereof
that are integral multiples of $1,000 in principal amount), on a date selected by the Company (the “Fundamental Change
Repurchase Date”), which shall be no later than thirty five (35) Business Days, and no earlier than twenty (20) Business
Days, after the date the Fundamental Change Notice is delivered in accordance with Section 3.02(b), at a price, payable in cash,
equal to one hundred percent (100%) of the principal amount of the Securities (or portions thereof) to be so repurchased, plus
accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change
Repurchase Price”), upon:

 

(i)          delivery
to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the
Fundamental Change Notice, no later than the Close of Business on the Business Day immediately preceding the Fundamental Change
Repurchase Date, of a Repurchase Notice, in the form set forth in the Securities or any other form of written notice substantially
similar thereto, in each case, duly completed and signed, with appropriate signature guarantee, stating:

 

(A)         the
certificate number(s) of the Securities that the Holder will deliver to be repurchased, if such Securities are Physical Securities;

 

(B)         the
principal amount of Securities to be repurchased, which must be $1,000 or an integral multiple thereof; and

 

(C)         that
such principal amount of Securities are to be repurchased pursuant to the terms and conditions specified in this Section 3.02;
and

 

(ii)         delivery
to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the
Fundamental Change Notice, at any time after the delivery of such Repurchase Notice, of such Securities (together with all necessary
endorsements) with respect to which the Fundamental Change Repurchase Right is being exercised;

 

    	-16-

    	 

    

 

provided, however, that if such Fundamental
Change Repurchase Date is after a Record Date for the payment of an installment of interest and on or before the related Interest
Payment Date, then the full amount of accrued and unpaid interest, if any, to, but excluding, such Interest Payment Date shall
be paid on such Interest Payment Date to the Holder of record of such Securities at the Close of Business on such Record Date
(without any surrender of such Securities by such Holder), and the Fundamental Change Repurchase Price shall not include any accrued
but unpaid interest. 

If such Securities
are held in book-entry form through the Depositary, the delivery of any Securities, Repurchase Notice, Fundamental Change Notice
or notice of withdrawal pursuant to the second immediately succeeding paragraph shall comply with applicable procedures of the
Depositary.

 

Upon such delivery
of Securities to the Company (if it is acting as its own Paying Agent) or such Paying Agent, such Holder shall be entitled to receive,
upon request, from the Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit evidencing such delivery.

 

Notwithstanding anything
herein to the contrary, any Holder that has delivered the Repurchase Notice contemplated by this Section 3.02(a) to the Company
(if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Fundamental Change
Notice shall have the right to withdraw such Repurchase Notice by delivery, at any time prior to the Close of Business on the Business
Day immediately preceding the Fundamental Change Repurchase Date (or, if there shall be a Default in the payment of the Fundamental
Change Repurchase, at any time during which such Default is continuing), of a written notice of withdrawal to the Company (if acting
as its own Paying Agent) or the Paying Agent, which notice shall be delivered in accordance with, and contain the information specified
in, Section 3.02(b)(x).

 

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

 

(b)          Within
ten (10) days after the occurrence of a Fundamental Change, the Company shall deliver, or cause to be delivered, to all Holders
of the Securities, and to beneficial owners as required by applicable law, a notice (the “Fundamental Change Notice”)
of the occurrence of such Fundamental Change and the Fundamental Change Repurchase Right arising as a result thereof. The Company
shall deliver a copy of the Fundamental Change Notice to the Trustee and publically release, through a reputable national United
States newswire service, a notice of the Fundamental Change. Each Fundamental Change Notice shall state:

 

(i)          the

Security on the principal amount of such Security, and such Security shall be convertible pursuant to Article 10 if any Repurchase
Notice with respect to such Security is withdrawn pursuant to this Section 3.02.

 

(h)          Any
Security that is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this Section

the other provisions of this Section 3.02, the Company will not be required to make a Fundamental Change purchase offer upon a
Fundamental Change if (i) a third party makes the Fundamental Change purchase offer in the manner, at the times and otherwise in
compliance with the requirements set forth in this Section 3.02 as if made by the Company and such third party purchases all Securities
properly tendered and not withdrawn under such Fundamental Change purchase offer, or (ii) if the Company’s obligations under
the Indenture are discharged pursuant to Article 8 on or promptly following the Fundamental Change. A Fundamental Change purchase
offer pursuant to this Section 3.02 may be made in advance of a Fundamental Change and may be conditional upon the occurrence of
a Fundamental Change if a definitive agreement is in place for the Fundamental Change at the time the Fundamental Change purchase
offer is made.

date money sufficient to pay the amount then due with respect to the Securities (unless there shall be a Default in the payment
of such amounts to the respective Holder(s)). The Company will pay, in money of the United States that at the time of payment is
legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which amounts shall
be paid (a) in the case of a Global Security, by wire transfer of immediately available funds to the account designated by the
Depositary or its nominee; (b) in the case of a Physical Security that is held by a Holder of more than five million dollars ($5,000,000)

surrendered for registration of transfer or exchange, payment or conversion. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain,
or fail to cause to maintain, any such required office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations and surrenders may be made or served at the Corporate Trust Office of the Trustee. The Company will maintain,

be at the principal office of the Company located in the United States.

 

The Company may also
from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations; provided, however, that no such designation
or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan,
The City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

to the Exchange Act (after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act); provided,
however, that each such report will be deemed to be so provided to the Trustee if the Company files such report with the
SEC through the SEC’s EDGAR database no later than the time such report is required to be filed with the SEC pursuant to
the Exchange Act (taking into account any applicable grace periods provided thereunder).

 

(c)          Delivery
of such reports, information and documents to the Trustee pursuant to this Section 4.03 is for informational purposes only, and

Trustee is entitled to rely exclusively on an Officers’ Certificates).

 

Section 4.04. Compliance
Certificate. The Company shall deliver to the Trustee, within one hundred and twenty (120) calendar days after the end of

such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Existence. Subject to Article 5, the Company will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence, in accordance with its organizational documents, and the rights (charter and statutory),
licenses and franchises of the Company; provided, however, that the Company shall not be required to preserve any such
right, license or franchise if in the judgment of the Board of Directors, such preservation or existence is not in the best interest
of, or is not material to the conduct of, the business of the Company.

 

Section 4.07. Notice
of Default. Within thirty (30) calendar days of the Company’s becoming aware of the occurrence of any Default or Event

after the last date of original issuance of the Securities, the Company fails to timely file any document or report that the Company
is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all
applicable grace periods thereunder and other than current reports on Form 8-K), or the Securities are not otherwise freely tradable
by Holders that are not the Company’s Affiliates and that were not the Company’s Affiliates within the three immediately
preceding months (as a result of restrictions pursuant to United States securities law the terms of this Indenture or the Securities),
the Company shall pay Additional Interest on the applicable Securities at a rate of one-half of one percent (0.50%) per annum
of the principal amount of Securities outstanding for each day during such period for which the Company’s failure to file
has occurred and is continuing or the applicable Securities are not otherwise freely tradable by Holders, other than the Company’s
Affiliates or Holders that were Affiliates of the Company within the three (3) immediately preceding months.

and that were not the Company’s Affiliates within the three (3) immediately preceding months (as a result of restrictions
pursuant to United States securities laws or the terms of this Indenture or the Securities), as of the three hundred and seventy-fifth

at a rate equal to one-half of one percent (0.50% ) per annum of the principal amount of Securities outstanding for each day after
the three hundred and seventy fifth (375th) day after the last date of original issuance of the Securities until i) the Security
Private Placement Legend has been removed, ii) the Securities are assigned an unrestricted CUSIP number and iii) the Securities
are otherwise freely tradable (without restrictions pursuant to United States securities law or the terms of this Indenture or
the Securities) by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company within the
three (3) immediately preceding months.

 

    	-23-

    	 

    

 

(c)          Notwithstanding
the foregoing, if the restrictive legend on the Securities has not been removed, the Securities are not assigned an unrestricted
CUSIP number or the Securities are not otherwise freely tradable by Holders that are not Affiliates and that were not Affiliates
within the three (3) immediately preceding months (as a result of restrictions pursuant to United States securities law or the
terms of this Indenture or the Securities), the Company may elect to designate an effective shelf registration statement for the
resale of the Securities and any Common Stock issuable upon conversion of the Securities. Additional interest shall not accrue
or be payable under this Section 4.09 for each day on which such registration statement remains effective and usable by Holders
for the resale of the Securities and any Common Stock. Any such registration will be effected on terms customary for convertible
notes generally offered in reliance upon Rule 144A under the Securities Act.

 

(d)          Additional
Interest payable in accordance with Section 4.09(a) and Section 4.09(b) shall be payable in arrears on each Interest Payment Date
for the Securities in the same manner as regular interest on the Securities and will be in addition to any Additional Interest
accruing pursuant to Section 6.02(b).

the event that the Company is required to pay Additional Interest to Holders of Securities (whether pursuant to this Section 4.09
or Section 6.02(b)), the Company shall provide written notice (“Additional Interest Notice”) to the Trustee
of its obligation to pay Additional Interest no later than fifteen (15) calendar days prior to the proposed payment date for the
Additional Interest. Each Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Company
on such payment date. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine the amount
of Additional Interest, or with respect to the nature, extent or calculation of the amount of Additional Interest owed, or with
respect to the method employed in such calculation of the Additional Interest.

Successors

 

Section 5.01. When
Company May Merge, Etc.   The Company shall not consolidate with, or merge with or into, or sell, transfer, lease, convey
or otherwise dispose of all or substantially all of the consolidated property or assets of the Company to another Person,
whether in a single transaction or series of related transactions, unless (i) the Company is the continuing corporation or
such other Person is a corporation organized and existing under the laws of the United States, any state of the United States
or the District of Columbia, and such other corporation assumes by supplemental indenture all of the obligations of the
Company under the Securities and this Indenture and (ii) immediately after giving effect to such transaction or series
of transactions, no Default or Event of Default shall exist.

 

For purposes of this
Section 5.01, the sale, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets
of one or more Subsidiaries of the Company to another Person, which properties or assets, if held by the Company instead of such
Subsidiaries, would constitute all or substantially all of the properties or assets of the Company on a consolidated basis, shall
be deemed to be the sale, transfer, lease, conveyance or other disposition of all or substantially all of the consolidated properties
or assets of the Company to another Person.

 

    	-24-

    	 

    

 

The Company shall deliver
to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing effect and
an Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence of Defaults and Events of Default)
stating that the proposed transaction and such supplemental indenture will, upon consummation of the proposed transaction, comply
with this Indenture.

 

This Section 5.01 shall
not apply to any sale, transfer, lease, conveyance or other disposition of assets between or among the Company and its Subsidiaries.

 

Section 5.02. Successor
Substituted. In case of any such consolidation, merger or any sale, transfer, lease, conveyance or other disposition of all
or substantially all of the consolidated property or assets of the Company and upon the assumption by the successor Person, by
supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual
payment of the principal of and accrued and unpaid interest on all of the Securities, the due and punctual payment of the Fundamental
Change Repurchase Price with respect to all Securities repurchased on each Fundamental Change Repurchase Date, the due and punctual
delivery or payment, as the case may be, of any consideration due upon conversion of the Securities and the due and punctual performance
of all of the covenants and conditions of this Indenture and the Securities to be performed by the Company, such successor Person
shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first
part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of the Company
any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any
Securities that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication,
and any Securities that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose.
All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued
at the date of the execution hereof. In the event of any such consolidation, merger or any sale, transfer, conveyance or other
disposition (but not in the case of a lease), upon compliance with this Article 5 the Person named as the “Company”
in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this
Article 5 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall
be released from its liabilities as obligor and maker of the Securities and its obligations under this Indenture shall terminate.

 

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

written notice on their behalf, the Trustee shall do so. When a Default is cured, it ceases to exist for all purposes under this
Indenture.

 

The conversion of the
Securities pursuant to the terms hereof shall not be a Default or Event of Default under clause (f) above.

 

Section 6.02. Acceleration.
(a) If an Event of Default (excluding an Event of Default specified in Section 6.01(h) or (i) with respect to the Company,
but including an Event of Default specified in Section 6.01(h) or (i) solely with respect to a Significant Subsidiary of the Company
or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) has occurred and
is continuing, either the Trustee, by written notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate
principal amount of the Securities then outstanding, by written notice to the Company and the Trustee, may declare the Securities
to be immediately due and payable in full. Upon such declaration, the principal of, and any accrued and unpaid interest on, all
Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(h) or (i) with respect to the
Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(h) or (i) solely with respect
to a Significant Subsidiary of the Company or any group of its Subsidiaries that in the aggregate would constitute a Significant
Subsidiary of the Company) occurs, the principal of, and accrued and unpaid interest on, all the Securities shall ipso facto
become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders
of a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may rescind or
annul an acceleration and its consequences if (i) the rescission would not conflict with any order or decree, (ii) all existing
Events of Default, except the nonpayment of principal or interest that has become due solely because of the acceleration, have
been cured or waived and (iii) all amounts due to the Trustee under Section 7.06 have been paid.

(b)          Notwithstanding
the foregoing, for the first one hundred and eighty (180) days immediately following an Event of Default relating to failure to
comply with Section 4.03(b), (which will be the sixtieth (60th) day after written notice is provided to the Company of the Default
pursuant to the last paragraph of Section 6.01, unless such failure is cured or waived on or before such sixtieth (60th) day),
the sole remedy for any such Event of Default shall, at the Company’s election, be the accrual of Additional Interest on
the Securities at a rate per year equal to one-half of one percent (0.50%) of the outstanding principal amount of Securities, payable
semi-annually at the same time and in the same manner as regular interest payable on the Securities. Such Additional Interest shall
accrue on all outstanding Securities from, and including, the date on which such Event of Default first occurs to, and including,
the one hundred and eighty-first (181st) day thereafter (or such earlier date on which such Event of Default shall have been cured
or waived). In addition to the accrual of such Additional Interest, on and after the one hundred and eighty-first (181st) day immediately
following such Event of Default if the Company elected to pay Additional Interest pursuant to this Section 6.02(b) such Additional
Interest will cease to accrue and, if such Event of Default has not been cured or waived prior to such one hundred and eighty-first
(181st) day, the Holders or the Trustee may accelerate the Securities as provided in Section 6.02(a) above. Additional Interest
payable in accordance with this Section 6.02(b) shall be payable in arrears on each Interest Payment Date for the Securities in
the same manner as regular interest on the Securities and will be in addition to any Additional Interest accruing pursuant to Section
4.09(a) or Section 4.09(b).

 

Section 6.03. Other
Remedies. Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities
or to enforce the performance of any provision of the Securities or this Indenture.

 

The Trustee may maintain
a proceeding even if it does not possess any of the Securities or does not produce any of them 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 shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative.

 

Section 6.04. Waiver
of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities
then outstanding may, by notice to the Trustee, waive any past Default or Event of Default and its consequences, other than a Default
or Event of Default (a) in the payment of the principal of, or interest on, any Security, or in the payment of the Fundamental
Change Repurchase Price, (b) arising from a failure by the Company to convert any Securities in accordance with this Indenture
or (c) in respect of any provision of this Indenture or the Securities which, under Section 9.02, cannot be modified or amended
without the consent of the Holder of each outstanding Security affected. When a Default or an Event of Default is waived or cured,
it is cured and ceases to exist for all purposes under this Indenture.

 

    	-28-

    	 

    

 

Section 6.05. Control
by Majority. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred
on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, is unduly prejudicial
to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity reasonably
satisfactory to it; provided that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent
with such direction.

 

Section 6.06. Limitation
on Suits. Except with respect to any proceeding instituted in accordance with Section 6.07, a Holder shall not have any right
to institute any proceeding under this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under
this Indenture unless:

 

(a)          the
Holder gives the Trustee written notice of a continuing Event of Default;

 

(b)          the
Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding make a written request
to the Trustee to pursue the remedy;

 

(c)          the
Holder or Holders offer and, if requested, provide to the Trustee indemnity that is reasonably satisfactory to the Trustee against
any loss, liability or expense to or of the Trustee in connection with pursuing such remedy; and

 

(d)          the
Trustee fails to comply with the request within sixty (60) days after receipt of such notice, request and offer of reasonable indemnity,
and during such sixty (60) day period, the Holders of a majority in aggregate principal amount of the Securities then outstanding
do not give the Trustee a direction that is inconsistent with the request.

 

A Holder may not use
this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

 

Section 6.07. Rights
of Holders to Receive Payment and to Convert Securities. Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of all amounts (including any principal, interest or the Fundamental Change Repurchase Price) due
with respect to the Securities, on or after the respective due dates as provided herein, or to bring suit for the enforcement of
any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

 

In addition, notwithstanding
any other provision of this Indenture, the right of any Holder to convert a Security in accordance with this Indenture, or to bring
suit for the enforcement of such right, shall not be impaired or affected without the consent of the Holder.

 

    	-29-

    	 

    

 

Section 6.08. Collection
Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) has occurred and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the Company for the whole amount due with respect to
the Securities, including any unpaid and accrued interest.

 

Section 6.09. Trustee
May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee, any predecessor Trustee and the Holders allowed in any judicial proceedings relative
to the Company or its creditors or properties.

 

The Trustee may collect
and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or similar official in any judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly
to the Holders, to pay the Trustee any amount due 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 7.06.

 

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

 

Section 6.10. Priorities.
If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

 

	 	First:	to the Trustee for amounts due under Section 7.06;

 

	 	Second:	to Holders for all amounts due and unpaid on the Securities, without preference or priority of any kind, according to the amounts due and payable on the Securities; and

 

	 	Third:	the balance, if any, to the Company.

 

The Trustee, upon prior
written notice to the Company, may fix a record date and payment date for any payment by it to Holders pursuant to this Section
6.10. At least fifteen (15) days before each such record date, the Trustee shall deliver to each Holder and the Company a written
notice that states such record date and payment date and the amount of such payment.

 

Section 6.11. Undertaking
for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit
other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys’ fees, 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.07 or a suit by Holders of more than ten percent (10%) in aggregate principal amount of the outstanding Securities.

Trustee

 

Section 7.01. Duties
of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise

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

Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,

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

 

(ii)         the
Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received
by it pursuant to Section 6.05; and

 

(iii)        this
paragraph does not limit the effect of Section 7.01(b).

law and shall be invested by the Trustee pursuant to the written instructions of the Company reasonably satisfactory to the Trustee.

 

(f)          No
provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability

grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured
to it.

 

    	-31-

    	 

    

 

Section 7.02. Rights
of Trustee. (a) Subject to Section 7.01, the Trustee may conclusively rely on any document believed by it to be genuine and
to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document;
if, however, the Trustee shall determine to make such further inquiry or investigation, it shall be entitled during normal business
hours to examine the relevant books, records and premises of the Company, personally or by agent or attorney upon reasonable prior
notice, at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry
or investigation.

 

(b)          Before
the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel (or both an Officers’
Certificate and an Opinion of Counsel). The Trustee shall not be liable for any action it takes or omits to take in good faith
in reliance on such Officers’ Certificate or Opinion of Counsel.

(f)          The
Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within
its discretion, rights or powers conferred upon it by this Indenture; provided that the Trustee’s action does not
constitute willful misconduct or negligence.

 

(g)          The
Trustee shall have no duty to inquire as to the performance of the Company with respect to the covenants contained in Article 4
if the Trustee is not also acting as Paying Agent. In addition, the Trustee shall not be deemed to have knowledge of an Event of
Default except any Default or Event of Default of which a Responsible Officer of the Trustee who shall have direct responsibility
for the administration of this Indenture shall have received written notification or obtained actual knowledge. Delivery of reports,
information and documents to the Trustee under Article 4 (other than Sections 4.04 and 4.07) is for informational purposes only
and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein
or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely on Officers’ Certificates).

 

    	-32-

    	 

    

 

(h)          The
Trustee shall be under no obligation to exercise any of the rights or powers vested by this Indenture at the request or demand
of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee security or indemnity reasonably
satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request
or demand.

 

(i)          The
rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation, its right to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other
Person employed to act hereunder.

 

(j)          The
Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals or titles of
officers (or both names and titles) authorized at such time to take specified actions pursuant to this Indenture, which Officers’
Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so
authorized in any such certificate previously delivered and not superseded.

 

(k)          The
Trustee will not be liable for any indirect, special, consequential, punitive or exemplary damages.

 

Section 7.03. Individual
Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or any of its Affiliates with the same rights the Trustee would have if it were not Trustee. Any
Securities Agent may do the same with like rights. The Trustee, however, must comply with Section 7.09.

 

Section 7.04. Trustee’s
Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities; the Trustee
shall not be accountable for the Company’s use of the proceeds from the Securities; and the Trustee shall not be responsible
for any statement in the Securities other than its certificate of authentication.

 

Section 7.05. Notice
of Defaults. If a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant
to the provisions of this Indenture, or as to which a Responsible Officer of the Trustee who shall have direct responsibility for
the administration of this Indenture shall have actual knowledge, then the Trustee shall deliver to each Holder a notice of the
Default or Event of Default within ninety (90) days after receipt of such notice or after acquiring such knowledge, as applicable,
unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of
a Default or Event of Default in payment or delivery of any amounts due (including principal, interest, the Fundamental Change
Repurchase Price or the consideration due upon conversion) with respect to any Security, the Trustee may withhold such notice if,
and so long as it in good faith determines that, withholding such notice is in the best interests of Holders.

 

Section 7.06. Compensation
and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as shall be agreed
upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.
The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it pursuant to, and
in accordance with, any provision hereof, except for any such expenses as shall have been caused by the Trustee’s own negligence,
bad faith or willful misconduct. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee’s
agents and counsel. The Trustee shall provide the Company with reasonable notice of any expense not in the ordinary course of business.

 

    	-33-

    	 

    

 

The Company shall indemnify
each of the Trustee, each predecessor Trustee and their respective agents for, and hold each of them harmless against, any and
all loss, liability, damage, claim or expense (including the reasonable fees and expenses of counsel and taxes other than those
based upon the income of the Trustee) incurred by it in connection with the acceptance or administration of this trust and the
performance of its duties hereunder, including, without limitation, in connection with enforcing the provisions of this Section
7.06, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder
or any other Person) or liability in connection with the exercise or performance of any of its powers and duties hereunder. The
Company need not pay for any settlement made without its consent. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnification; provided that failure to give such notice shall not relieve the Company of its obligations
under this Section 7.06. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the
Trustee through the Trustee’s negligence, bad faith or willful misconduct.

 

To secure the Company’s
payment obligations in this Section 7.06, the Trustee shall have a lien prior to the Securities on all money or property held or
collected by the Trustee, except that held in trust to pay amounts due on particular Securities.

 

After the resignation
or removal of the Trustee under the Indenture, the indemnity and expense reimbursement provisions of Section 7.06 will continue
in effect for the benefit of such retiring or removed Trustee and its agents in respect of any actions taken or omitted to be taken
by any of them while the retiring or removed Trustee was acting as Trustee. The indemnity obligations of the Company with respect
to the Trustee provided for in this Section 7.06 shall survive any termination of this Indenture.

 

When the Trustee incurs
expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) occurs, the expenses and the compensation
for the services are intended to constitute expenses of administration under any Bankruptcy Law.

 

Section 7.07. Replacement
of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee’s acceptance of appointment as provided in this Section 7.07.

 

The Trustee may resign
by so notifying the Company in writing thirty (30) days prior to such resignation. The Holders of a majority in aggregate principal
amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and the Company in writing and may
appoint a successor Trustee with the Company’s consent. The Company may remove the Trustee if:

 

(a)          the
Trustee fails to comply with Section 7.09;

 

(b)          the
Trustee is adjudged a bankrupt or an insolvent;

 

    	-34-

    	 

    

 

(c)          a
receiver or other public officer takes charge of the Trustee or its property; or

 

(d)          the
Trustee becomes incapable of acting.

 

If the Trustee resigns
or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee.

 

If a successor Trustee
does not take office within thirty (30) days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company’s
expense), the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the outstanding Securities
may petition any court of competent jurisdiction for the appointment of a successor Trustee.

 

If the Trustee fails
to comply with Section 7.09, the Company or any Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

 

A successor Trustee
shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties
of the Trustee under this Indenture. The successor Trustee shall deliver a notice of its succession to Holders. The retiring Trustee
shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section
7.06.

 

Section 7.08. Successor
Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor
Trustee, if such successor corporation is otherwise eligible hereunder.

 

Section 7.09. Eligibility;
Disqualification. There shall at all times be a Trustee hereunder that (i) is an entity organized and doing business under
the laws of the United States of America or of any state thereof or the District of Columbia, (ii) is subject to supervision or
examination by federal or state authorities and (iii) has a combined capital and surplus of at least fifty million dollars ($50,000,000)
as set forth in its most recent published annual report of condition.

Discharge of Indenture

 

Section 8.01. Termination
of the Obligations of the Company. This Indenture shall cease to be of further effect, and the Trustee shall execute instruments
acknowledging satisfaction and discharge of this Indenture, if (a) either (i) all outstanding Securities (other than Securities
replaced pursuant to Section 2.07) have been delivered to the Trustee for cancellation or (ii) all outstanding Securities have
become due and payable at their scheduled maturity, upon conversion or upon Repurchase Upon Fundamental Change, and in either case
the Company irrevocably deposits, prior to the applicable due date, with the Trustee or the Paying Agent (if the Paying Agent is
not the Company or any of its Affiliates) cash or, in the case of conversion, shares of Common Stock (and cash in lieu of any fractional
shares) sufficient to satisfy all obligations due and owing on all outstanding Securities (other than Securities replaced pursuant
to Section 2.07) on the Maturity Date, the relevant settlement date of any conversion or the Fundamental Change Repurchase Date,
as the case may be; (b) the Company pays to the Trustee all other sums payable hereunder by the Company; (c) no Default or Event
of Default with respect to the Securities shall exist on the date of such deposit under clause (a)(ii) above; (d) such deposit
under clause (a)(ii) above shall not result in a breach or violation of, or constitute a Default or Event of Default under, this
Indenture; and (e) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating
that all conditions precedent provided for herein relating to the satisfaction and discharge of this Indenture have been complied
with; provided, however, that Sections 2.03, 2.04, 2.05, 2.08, 4.01, 4.02, 4.05, 7.02, 7.06, 7.07, 7.08, 7.09, 13.04,
13.08 and 13.13, and Articles 8 and 13shall survive any discharge of this Indenture until such time as the Securities have been
paid in full and there are no Securities outstanding; provided further, however, that Section 7.06 shall also survive after
the Securities are paid in full and there are no Securities outstanding.

 

Section 8.02. Application
of Trust Money. The Trustee shall hold in trust all money deposited with it pursuant to Section 8.01 and shall apply such deposited
money through the Paying Agent and in accordance with this Indenture to the payment of amounts due on the Securities.

 

Section 8.03. Repayment
to Company. The Trustee and the Paying Agent shall promptly notify the Company of, and pay to the Company upon the request
of the Company, any excess money held by them at any time. The Trustee or the Paying Agent, as the case may be, shall provide written
notice to the Company of any money that has been held by it and has, for a period of two (2) years, remained unclaimed for the
payment of the principal of, or any accrued and unpaid interest on, the Securities. Subject to applicable law, the Trustee and
the Paying Agent shall pay to the Company upon the written request of the Company any money held by them for the payment of the
principal of, or any accrued and unpaid interest on, the Securities that remains unclaimed for two (2) years; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Company,
cause to be published (in no event later than five (5) days after the Company requests repayment) once in a newspaper of general
circulation in the City of New York or cause to be delivered to each Holder, notice stating that such money remains unclaimed and
that, after a date specified therein, which shall not be less than thirty (30) days from the date of such publication or delivery,
any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled
to the money must look to the Company for payment as general creditors, subject to applicable law, and all liability of the Trustee
and the Paying Agent with respect to such money and payment shall, subject to applicable law, cease.

 

Section 8.04. Reinstatement.
If the Trustee or Paying Agent is unable to apply any money in accordance with Sections 8.01 and 8.02 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the obligations of the Company under this Indenture and the Securities shall be revived and reinstated as though
no deposit had occurred pursuant to Sections 8.01 and 8.02 until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Sections 8.01 and 8.02; provided, however, that if the Company has made any payment
of amounts due with respect to any Securities because of the reinstatement of its obligations, then the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

add to the covenants of the Company described in this Indenture for the benefit of Holders or to surrender any right or power conferred
upon the Company;

 

(f)          to
add events of default with respect to the Securities;

 

(g)          to
add circumstances under which the Company will pay additional interest on the Securities;

 

(h)          to
make any change that does not adversely affect any outstanding Security;

 

(i)          to
make provision with respect to adjustments to the Conversion Rate as required by this Indenture or to increase the Conversion Rate
in accordance with this Indenture; or

 

(j)          to
comply with the requirement of the SEC in connection with any qualification of this Indenture under the TIA.

 

In addition, the Company
and the Trustee may enter into a supplemental indenture without the consent of Holders of the Securities to (i) cure any ambiguity,
defect, omission or inconsistency in this Indenture in a manner that does not, individually or in the aggregate with all other
changes, adversely affect the rights of any Holder in any respect or (ii) to conform the Indenture or the Securities to the description
thereof contained in the Offering Memorandum under the heading “Description of the Notes.”

Section 9.02. With
Consent of Holders. The Company may amend or supplement this Indenture or the Securities with the consent of the Holders of
at least a majority in aggregate principal amount of the outstanding Securities (including, without limitation, consents obtained
from Holders in connection with a purchase of, or tender or exchange offer for, Securities). Subject to Sections 6.04 and 6.07,
the Holders of a majority in aggregate principal amount of the outstanding Securities may, by notice to the Trustee, waive by consent
(including, without limitation, consents obtained from Holders in connection with a purchase of, or tender or exchange offer for,
Securities) compliance by the Company with any provision of this Indenture or the Securities without notice to any other Holder.
Notwithstanding the foregoing or anything herein to the contrary, without the consent of the Holder of each outstanding Security
affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not:

 

(a)          change
the stated maturity of the principal of, or the payment date of any installment of interest on, any Security;

 

(b)          reduce
the principal amount of, or any interest on, any Security;

 

(c)          change
the place, manner or currency of payment of principal of, or any interest on, any Security;

 

(d)          impair
the right to institute suit for the enforcement of any delivery or payment on, or with respect to, or due upon the conversion of,
any Security;

 

(e)          reduce
any amount payable upon repurchase of any Security or change the time at which or circumstances under which the Securities may
or shall be repurchased (in each case including pursuant to Section 3.02);

 

(f)          adversely
affect the right of Holders to convert Securities in accordance with Article 10;

 

(g)          reduce
the percentage in aggregate principal amount of outstanding Securities whose Holders must consent to a modification to or amendment
of any provision of this Indenture or the Securities; or

 

(h)          modify
the provisions of this Indenture with respect to modification and waiver (including waiver of a Default or an Event of Default),
except to increase the percentage required for modification or waiver or to provide for the consent of each affected Holder.

 

Promptly after an amendment,
supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall deliver, or cause to be delivered,
to Holders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to deliver such notice
shall not in any way impair or affect the validity of such amendment, supplement or waiver.

 

It shall not be necessary
for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or
waiver, but it shall be sufficient if such consent approves the substance thereof.

 

    	-38-

    	 

    

  

Section 9.03. Revocation
and Effect of Consents. 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 Security or portion of a Security that evidences the same debt as the consenting
Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder
may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the
date the amendment, supplement or waiver becomes effective.

 

After an amendment,
supplement or waiver becomes effective with respect to the Securities, it shall bind every Holder unless such amendment, supplement
or waiver makes a change that requires, pursuant to Section 9.02, the consent of each Holder affected. In that case, the amendment,
supplement or waiver shall bind each Holder of a Security who has consented to it and, provided that notice of such amendment,
supplement or waiver is reflected on a Security that evidences the same debt as the consenting Holder’s Security, every subsequent
Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

 

Nothing in this Section
9.03 shall impair the Company’s rights pursuant to Section 9.01 to amend this Indenture or the Securities without the consent
of any Holder in the manner set forth in, and permitted by, such Section 9.01.

 

Section 9.04. Notation
on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require
the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security as directed
and prepared by the Company about the changed terms and return it to the Holder. Alternatively, if the Company so determines, the
Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

 

Section 9.05. Trustee
Protected. The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article 9; provided,
however, that the Trustee need not sign any amendment, supplement or waiver authorized pursuant to this Article 9 that adversely
affects the Trustee’s rights, duties, liabilities or immunities. The Trustee shall be entitled to receive and conclusively
rely upon an Opinion of Counsel as to legal matters and an Officers’ Certificate as to factual matters that any supplemental
indenture, amendment or waiver is permitted or authorized pursuant to this Indenture.

 

Section 9.06. Effect
of Supplemental Indentures. Upon the due execution and delivery of any supplemental indenture in accordance with this Article
9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture
for all purposes, and, except as set forth in Sections 9.02 and 9.03, every Holder of Securities shall be bound thereby.

 

Article
10

Conversion

 

Section 10.01. Conversion
Privilege. (a)  Subject to Section 3.02 and Section 10.02 and the settlement provisions of Section 10.15(c), the
Securities shall be convertible at any time prior to the Close of Business on the Business Day immediately preceding the Maturity
Date into shares of Common Stock and cash in lieu of fractional shares of Common Stock as described in Section 10.03 and in accordance
with this Article 10.

 

    	-39-

    	 

    

 

(b)          A
Holder may convert a portion of the principal amount of a Security if such portion is $1,000 principal amount or an integral multiple
of $1,000 principal amount. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion
of a portion of such Security.

 

Section 10.02. Conversion
Procedure and Payment Upon Conversion. (a)  To convert its Security, a Holder of a Physical Security must (i) complete
and manually sign the Conversion Notice, with appropriate signature guarantee or facsimile of the Conversion Notice, and deliver
the completed Conversion Notice to the Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii) furnish
appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (iv) pay all transfer or similar
taxes if required pursuant to Section 10.04 and (v) pay funds equal to interest payable in on the next Interest Payment Date required
by Section 10.02(c). If a Holder holds a beneficial interest in a Global Security, to convert such Security, the Holder must comply
with clauses (iv) and (v) above and the Depositary’s procedures for converting a beneficial interest in a Global Security.
A Holder’s valid election to convert its Security is irrevocable.

 

Upon conversion of
a Holder’s Security, the Company shall deliver to each converting Holder, through the Conversion Agent, a number of shares
of Common Stock equal to (i) (A) the aggregate principal amount of Securities to be converted, divided by (B) $1,000, multiplied
by (ii) the Conversion Rate in effect on the relevant Conversion Date (provided that the Company shall deliver cash
in lieu of fractional shares as described in Section 10.03). Settlement shall occur on the third (3rd) Business Day immediately
following the relevant Conversion Date.

 

(b)          Each
conversion shall be deemed to have been effected as to any Securities surrendered for conversion at the Close of Business on the
applicable Conversion Date, and the Person in whose name the shares of Common Stock shall be issuable upon such conversion shall
become the holder of record of such shares as of the Close of Business on such Conversion Date. Prior to such time, a Holder receiving
shares of Common Stock upon conversion shall not be entitled to any rights relating to such shares of Common Stock, including,
among other things, the right to vote and receive dividends and notices of shareholder meetings. On and after the Close of Business
on the Conversion Date with respect to a conversion of a Security pursuant hereto, all rights of the Holder of such Security shall
terminate, other than the right to receive the consideration deliverable or payable upon conversion of such Security as provided
herein and accrued but unpaid interest, if any, on such Security as provided herein.

 

    	-40-

    	 

    

 

(c)          Except
as provided in the Securities or in this Article 10, no payment or adjustment will be made for accrued interest on a converted
Security, and accrued interest, if any, will be deemed to be paid by the consideration paid to the Holder upon conversion. Such
accrued interest, if any, shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. If any Holder surrenders
a Security for conversion after the Close of Business on the Record Date for the payment of an installment of interest but prior
to the Open of Business on the next Interest Payment Date, then, notwithstanding such conversion, the full amount of interest payable
with respect to such Security on such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record
of such Security at the Close of Business on such Record Date; provided, however, that such Security, when surrendered
for conversion, must be accompanied by payment in cash to the Conversion Agent on behalf of the Company of an amount equal to the
full amount of interest payable on such Interest Payment Date on the Security so converted; provided further, however,
that such payment to the Conversion Agent described in the immediately preceding proviso in respect of a Security surrendered for
conversion shall not be required with respect to a Security that (i) is surrendered for conversion after the Close of Business
on the Record Date immediately preceding the Maturity Date or (ii) is surrendered for conversion after the Close of Business on
a Record Date for the payment of an installment of interest and on or prior to the Open of Business on the related Interest Payment
Date, where, pursuant to Section 3.02, the Company has specified, with respect to a Fundamental Change, a Fundamental Change Repurchase
Date that is after such Record Date but on or prior to such Interest Payment Date; provided further that, if the
Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of interest on such Security,
then in no event shall the Holder of such Security who surrenders such Security for conversion be required to pay such defaulted
interest or the interest that shall have accrued on such defaulted interest pursuant to Section 2.12 or otherwise (it being understood
that nothing in this Section 10.02(c) shall affect the Company’s obligations under Section 2.12).

 

(d)          If
a Holder converts more than one Security at the same time, the full number of shares of Common Stock issuable upon such conversion
(and, as a result, the amount of cash deliverable in lieu of any fractional share of Common Stock) shall be based on the total
principal amount of all Securities converted.

 

(e)          Upon
surrender of a Security that is converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal
amount to the unconverted portion of the Security surrendered.

 

Section 10.03. Cash
in Lieu of Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Security.
Instead, the Company shall pay cash in lieu of fractional shares based on the Closing Sale Price of the Common Stock on the applicable
Conversion Date (or, if such Conversion Date is not a Trading Day, the Closing Sale Price of the Common Stock on the Trading Day
immediately preceding such Conversion Date).

 

Section 10.04. Taxes
on Conversion. If a Holder converts its Security, the Company shall pay any documentary, stamp or similar issue or transfer
tax or duty due on the issue, if any, of Common Stock upon the conversion. However, such Holder shall pay any such tax or duty
that is due because such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver
a certificate representing the Common Stock to be issued in a name other than such Holder’s name until the Conversion Agent
receives a sum sufficient to pay any tax or duty which will be due because such shares are to be issued in a name other than such
Holder’s name.

 

Section 10.05. Company
to Provide Common Stock. The Company shall at all times reserve out of its authorized but unissued Common Stock or Common Stock
held in its treasury enough shares of Common Stock to permit the conversion, in accordance herewith, of all of the Securities (assuming,
for such purposes, that at the time of computation of such number of shares, all such Securities would be converted by a single
Holder). The shares of Common Stock due upon conversion of a Global Security shall be delivered by the Company in accordance with
the Depositary’s customary practices.

 

    	-41-

    	 

    

 

All shares of Common
Stock issued upon conversion of the Securities shall be validly issued, fully paid and non-assessable and shall be free of preemptive
or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company.

 

The Company shall comply
with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities and shall list
such shares on each national securities exchange or automated quotation system on which the shares of Common Stock are listed on
the applicable Conversion Date.

 

Section 10.06. Adjustment
of Conversion Rate. The Conversion Rate shall be subject to adjustment from time to time, without duplication, upon the occurrence
of any of the following events:

 

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

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or share combination, as the case may be;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such dividend or distribution, or immediately after the Open of Business on the effective date of such share split or share combination, as the case may be;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex Date for such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or share combination, as the case may be; and
	 	 	 
	OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, or such share split or share combination, as the case may be.

 

Any adjustment made
under this Section 10.06(a) shall become effective immediately after the Open of Business on the Ex 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 the case may be.
If any dividend or distribution of the type described in this Section 10.06(a) is declared but not so paid or made, then the Conversion
Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution,
to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

 

    	-42-

    	 

    

 

(b)          If
the Company distributes to all or substantially all holders of the Common Stock any rights, options or warrants entitling them,
for a period expiring not more than sixty (60) days immediately following the record date of such distribution, to purchase or
subscribe for shares of Common Stock, at a price per share less than the average of the Closing Sale Prices of the Common Stock
over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such
distribution, the Conversion Rate shall be increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such distribution;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on the Ex Date for such distribution;
	 	 	 
	X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	 	 	 
	Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such distribution.

 

Any increase made under
this Section 10.06(b) shall be made successively whenever any such rights, options or warrants are distributed and shall become
effective immediately after the Open of Business on the Ex Date for such distribution. To the extent that shares of Common Stock
are not delivered after expiration of such rights, options or warrants, the Conversion Rate shall be readjusted, effective as of
the date of such expiration, to the Conversion Rate that would then be in effect had the increase with respect to the distribution
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 distributed, the Conversion Rate shall be decreased, effective as of the date the
Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such record
date for such distribution had not occurred.

 

    	-43-

    	 

    

 

In determining whether
any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average
of the Closing Sale Prices for the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the
date of announcement for such distribution, and in determining the aggregate offering price of such shares of Common Stock, there
shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable
on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.
Except in the case of a readjustment of the Conversion Rate pursuant to the immediately preceding paragraph, the Conversion Rate
shall not be decreased pursuant to this Section 10.06(b).

 

(c)          If
the Company distributes shares of its Capital Stock, evidences of its indebtedness or other of its assets, securities or property
or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of Common
Stock, but excluding (i) dividends or distributions as to which an adjustment was effected pursuant to Section 10.06(a) or
Section 10.06(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section
10.06(d), and (iii) Spin-Offs to which the provisions set forth in the latter portion of this Section 10.06(c) shall apply
(any of such shares of Capital Stock, indebtedness or other assets, securities or property or rights, options or warrants to acquire
its Capital Stock or other securities, the “Distributed Property”), then, in each such case the Conversion Rate
shall be increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such distribution;
	 	 	 
	SP0	=	the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the Ex Date for such distribution; and
	 	 	 
	FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property distributable with respect to each outstanding share of Common Stock as of the Close of Business on the Ex Date for such distribution.

 

If the Board of Directors
determines “FMV” for purposes of this Section 10.06(c) by reference to the actual or when issued trading market for
any securities, it must in doing so consider the prices in such market over the same period used in computing the Closing Sale
Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the
Ex Date for such distribution.

 

    	-44-

    	 

    

 

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, provision shall be made for each Holder of a Security to receive, for each $1,000 principal
amount of Securities it holds, at the same time and upon the same terms as the holders of the Common Stock, the amount and kind
of Distributed Property 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 increase made under
the portion of this Section 10.06(c) above shall become effective immediately after the Open of Business on the Ex Date for such
distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased, effective as of the date the
Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such dividend
or distribution had not been declared.

 

With respect to an
adjustment pursuant to this Section 10.06(c) where there has been a payment of a dividend or other distribution on the Common Stock
of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of
the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation
of the transaction) on a United States national securities exchange (a “Spin-Off”), the Conversion Rate shall
be increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the Close of Business on the last Trading Day of the Valuation Period (as defined below);
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Valuation Period;
	 	 	 
	FMV0	=	the average of the Closing 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 ten (10) consecutive Trading Days immediately following, and including, the Ex Date for a Spin-Off (the “Valuation Period”); and
	 	 	 
	MP0	=	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.

 

    	-45-

    	 

    

 

The increase to the
Conversion Rate under the preceding paragraph shall be given effect immediately after the Close of Business on the last Trading
Day of the Valuation Period; provided that, for purposes of determining the Conversion Rate, in respect of any conversion
during the Valuation Period, the reference within the portion of this Section 10.06(c) related to Spin-Offs to ten (10) consecutive
Trading Days shall be deemed replaced with such lesser number of consecutive Trading Days as have elapsed between the Ex Date for
such Spin-Off and the relevant Conversion Date, except that if such Conversion Date occurs on or after the Ex Date for the Spin-Off
and on or prior to the record date for the Spin-Off and the converting Holder would be treated as the record holder of shares of
the Common Stock as of the related Conversion Date as described under Section 10.02(b) based on an adjusted Conversion Rate for
such Ex Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment for such
Ex Date will not be made for such converting Holder and such Holder shall be treated as if such Holder were the record owner of
the shares of the Common Stock on an un-adjusted basis and participate in the Spin-Off.

 

Subject in all respects
to Section 10.14, rights, options or warrants distributed by the Company to all holders of its Common Stock entitling the holders
thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under
certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger
Event”): (i) are deemed to be transferred with such Common Stock; (ii) are not exercisable; and (iii) are also issued
in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.06(c)
(and no adjustment to the Conversion Rate under this Section 10.06(c) will be required) until the occurrence of the earliest Trigger
Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any
is required) to the Conversion Rate shall be made under this Section 10.06(c). If any such right, option or warrant, including
any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the
occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness
or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and
record date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights,
options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution)
of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect
thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 10.06(c) was made, (i) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased
without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give
effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share
redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants
(assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such
redemption or repurchase, and (ii) in the case of such rights, options or warrants that shall have expired or been terminated without
exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued.

 

    	-46-

    	 

    

 

Except in the case
of a readjustment of the Conversion Rate pursuant to the last sentence of either the fourth or seventh paragraph of this Section
10.06(c), the Conversion Rate shall not be decreased pursuant to this Section 10.06(c).

 

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

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex Date for such dividend or distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex Date for such dividend or distribution;
	 	 	 
	SP0	=	the last reported Closing Sale Price of the Common Stock on the Trading Day immediately preceding the Ex Date for such dividend or distribution; and
	 	 	 
	C	=	the amount in cash per share of Common Stock the Company distributes to holders of its Common Stock.

 

Such increase shall
become effective immediately after the Close of Business on the record date for such dividend or distribution.

 

Notwithstanding the
foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in
lieu of the foregoing increase, provision shall be made for each Holder of a Security to receive, for each $1,000 principal amount
of Securities it holds, at the same time and upon the same terms as holders of the Common Stock, the amount of cash such Holder
would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Ex Date for
such cash dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective
as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then
be in effect if such dividend or distribution had not been declared.

 

Except in the case
of a readjustment of the Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the Conversion Rate
shall not be decreased pursuant to this Section 10.06(d).

 

(e)          If
the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock, if
the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Closing 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 or exchange offer, the Conversion Rate shall be increased based on the following formula:

 

    	-47-

    	 

    

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the Close of Business on the last Trading Day of the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	 	 	 
	AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer);
	 	 	 
	OS1	=	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer); and
	 	 	 
	SP1	=	the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 

The increase to the
Conversion Rate under this Section 10.06(e) shall occur at the Close of Business on the last Trading Day of the ten (10) consecutive
Trading Day period commencing on, and including, the Trading Date next succeeding the date such tender or exchange offer expires;
provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten (10) Trading
Days immediately following and including the date that any such tender or exchange offer expires, references in this Section 10.06(e)
to ten (10) consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have
elapsed between the date such tender or exchange offer expires and the relevant Conversion Date. If the Company or one of its Subsidiaries
is obligated to purchase the Common Stock pursuant to any such tender or exchange offer but the Company or such Subsidiary is permanently
prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the Conversion Rate shall be
immediately decreased to the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

 

    	-48-

    	 

    

 

Except in the case
of a readjustment of the Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the Conversion Rate
shall not be decreased pursuant to this Section 10.06(e).

 

(f)          In
addition to the foregoing adjustments in subsections (a), (b), (c), (d) and (e) above, the Company may, from time to time and to
the extent permitted by law, increase the Conversion Rate by any amount for a period of at least twenty (20) Business Days or any
longer period as may be permitted or required by law, if the Board of Directors has made a determination, which determination shall
be conclusive, that such increase would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable
during such period. The Company shall give notice to the Trustee and cause notice of such increase to be delivered to each Holder
of Securities at such Holder’s address as the same appears on the registry books of the Registrar, at least fifteen (15)
days prior to the date on which such increase commences.

 

(g)          All
calculations under this Article 10 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be.
Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th.

 

Section 10.07. No
Adjustment. The Conversion Rate shall not be adjusted for any transaction or event other than for any transaction or event
described in this Article 10. Without limiting the foregoing, the Conversion Rate shall not be adjusted:

 

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

 

(ii)         upon
the issuance of any shares of Common Stock, restricted stock or restricted stock units, non-qualified stock options, incentive
stock options or any other options or rights (including stock appreciation rights) to purchase shares of Common Stock pursuant
to any present or future employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its
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 clause (ii) above and outstanding as of the date the Securities were first issued;

 

(iv)        for
accrued and unpaid interest, if any;

 

(v)         upon
the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction
that is not a tender offer or exchange offer of the nature described in Section 10.06(e);

 

    	-49-

    	 

    

 

(vi)        for
the sale or issuance of new shares of Common Stock or securities convertible into or exercisable for shares of Common Stock for
cash, including at a price per share less than the fair market value thereof or otherwise, except as described in Section 10.06;
or

 

(vii)       solely
for a change in the par value of shares of Common Stock.

 

No adjustment in the
Conversion Rate pursuant to Section 10.06(a) through (e) shall be required unless the cumulative adjustments would require an increase
or decrease of at least one percent (1%) of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion
Rate); provided, however, that any adjustments to the Conversion Rate which by reason of this paragraph are not required
to be made shall be carried forward and taken into account in any subsequent adjustment to the Conversion Rate; provided
further that all such carried forward adjustments shall be made with respect to the affected Securities on any Conversion
Date with respect to the Securities. The Company may not take any action pursuant to Section 10.01 to adjust the Conversion Rate
if that action would cause a reduction of the Conversion Price to less than the par value per share of the Common Stock.

 

No adjustment to the
Conversion Rate need be made pursuant to Section 10.06 for a transaction (other than for share splits or share combinations pursuant
to Section 10.06(a)) if the Company makes provision for each Holder to participate in the transaction, at the same time and upon
the same terms as holders of Common Stock participate in such transaction, without conversion, as if such Holder held a number
of shares of Common Stock equal to the Conversion Rate in effect on the record date or effective date, as applicable, of the transaction
(without giving effect to any adjustment pursuant to Section 10.06 on account of such transaction), multiplied by principal
amount (expressed in thousands) of Securities held by such Holder.

 

Section 10.08. Other
Adjustments. Whenever any provision of this Indenture requires the computation of an average of the Closing Sale Prices over
a period of multiple Trading Days, the Board of Directors, in its good faith determination, shall appropriately adjust such average
to account for any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the effective date, ex-dividend
date or expiration date of such event occurs at any time on or after the first Trading Day of such period and on or prior to the
last Trading Day of such period.

 

Section 10.09. Adjustments
for Tax Purposes. Except as prohibited by law the Company may (but is not obligated to) increase the Conversion Rate, in addition
to those required by Section 10.06 hereof, as it determines to be advisable in order that any stock dividend, subdivision of shares,
distribution of rights to purchase stock or securities or distribution of securities convertible into or exchangeable for stock
made by the Company or to its shareholders will not be taxable to the recipients thereof or in order to avoid or diminish any such
taxation.

 

Section 10.10. Notice
of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing
on the Registrar’s books a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating
the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness
of such adjustment.

 

    	-50-

    	 

    

 

Section 10.11. Notice
of Certain Transactions. In the event that:

 

(a)          the
Company takes any action, or becomes aware of any event, that would require an adjustment in the Conversion Rate,

 

(b)          the
Company takes any action that would require a supplemental indenture pursuant to Section 10.12, or

 

(c)          there
is a dissolution or liquidation of the Company,

 

the Company shall promptly mail to Holders
at the addresses appearing on the Registrar’s books and the Trustee a written notice stating the proposed record date, Ex
Date, effective date and expiration date, as applicable, of the transaction referred to in clause (a), (b) or (c) of this Section
10.11. If the transaction (A) is not a Spin-Off, but would require an adjustment to the Conversion Rate pursuant to Section 10.06(c),
or (B) would require an adjustment to the Conversion Rate pursuant to Section 10.06(d), the Company will use commercially reasonable
efforts to mail the notice at least fifteen (15) Business Days immediately prior to the Ex Date applicable to the transaction,
and, if the transaction (A) is a Spin-Off that would require an adjustment to the Conversion Rate pursuant to Section 10.06(c)
or (B) would require an adjustment to the Conversion Rate pursuant to Section 10.06(e), the Company will use commercially reasonable
efforts to mail the notice at least five (5) Business Days prior to the Ex Date or expiration date applicable to the transaction,
as the case may be.

 

Section 10.12. Effect
of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege. If the Company:

 

(a)          reclassifies
the Common Stock (other than a change only in par value, or from par value to no par value, or from no par value to par value,
or a change as a result of a subdivision or combination of Common Stock to which Section 10.06(a) applies);

 

(b)          is
party to a consolidation, merger or binding share exchange; or

 

(c)          sells,
transfers, leases, conveys or otherwise disposes of all or substantially all of the consolidated property or assets of the Company,

 

in each case, pursuant to which the Common
Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other property
(any such event, a “Merger Event”), each $1,000 principal amount of converted Securities will, from and after
the effective time of such Merger Event, be convertible into the same kind, type and proportions of consideration that a holder
of a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to such Merger Event would have
received in such Merger Event (“Reference Property”) and, prior to or at the effective time of such Merger Event,
the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture
permitted under Section 9.01(a) providing for such change in the right to convert the Securities.

 

    	-51-

    	 

    

 

If the Merger Event
causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined
based in part upon any form of stockholder election), then (i) the Reference Property into which the Securities 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 and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph
shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify
Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after
such determination is made.

 

The supplemental indenture
referred to in the first sentence of this Section 10.12 shall provide for adjustments to the Conversion Rate that shall be as nearly
equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 10 and for the delivery
of cash by the Company in lieu of fractional securities or property that would otherwise be deliverable to holders upon Conversion
as part of the Reference Property, with such amount of cash determined by the Board of Directors in a manner as nearly equivalent
as may be practicable to that used by the Company to determine the Closing Sale Price of the Common Stock. The provisions of this
Section 10.12 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances
or dispositions.

 

The Company shall not
become a party to any Merger Event unless its terms are consistent with this Section 10.12.

 

None of the foregoing
provisions shall affect the right of a Holder to convert its Securities into shares of Common Stock (and cash in lieu of any fractional
share) as set forth in Section 10.01 and Section 10.02 prior to the effective date of such Merger Event.

 

In the event the Company
shall execute a supplemental indenture pursuant to this Section 10.12, the Company shall promptly file with the Trustee an Officers’
Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities
upon the conversion of their Securities after any such Merger Event and any adjustment to be made with respect thereto.

 

Section 10.13. Trustee’s
Disclaimer. The Trustee has no duty to determine when an adjustment under this Article 10 should be made, how it should be
made or what such adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment, and shall
be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with
the Trustee pursuant to Section 10.10 hereof. The Trustee makes no representation as to the validity or value of any securities
or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the failure by the Company to comply
with any provisions of this Article 10.

 

The Trustee shall not
be under any responsibility to determine the correctness of the application of any supplemental indenture (executed pursuant to
Section 10.12) to an adjustment under this Article 10, but may accept as conclusive evidence of the correctness thereof, and shall
be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with
the Trustee pursuant to Section 10.12 hereof.

 

    	-52-

    	 

    

 

Section 10.14. Rights
Distributions Pursuant to Shareholders’ Rights Plans. To the extent that the Company adopts a rights plan (i.e.,
a poison pill) and such plan is in effect upon conversion of any Security or a portion thereof, the Company shall make provision
such that each Holder thereof shall receive, in addition to, and concurrently with the delivery of, the shares of Common Stock
due upon conversion, the rights described in such plan, unless the rights have separated from the Common Stock before the time
of conversion, in which case the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all
holders of Common Stock, Distributed Property as described in Section 10.06(c), subject to readjustment in the event of the expiration,
termination or redemption of such rights.

 

Section 10.15. Increased
Conversion Rate Applicable to Certain Securities Surrendered in Connection with Make-Whole Fundamental Changes. (a)  Notwithstanding
anything herein to the contrary, the Conversion Rate applicable to each Security that is surrendered for conversion, in accordance
with this Article 10, at any time during the period (the “Make-Whole Conversion Period”) from, and including,
the effective date (the “Effective Date”) of a Make-Whole Fundamental Change (which Effective Date the Company
shall disclose in the written notice referred to in Section 10.15(e)) (A) to, and including, the Close of Business on the date
that is thirty (30) Business Days after the later of (i) such Effective Date and (ii) the date the Company delivers to Holders
the relevant notice of the Effective Date or (B) if such Make-Whole Fundamental Change also constitutes a Fundamental Change, to,
and including, the Close of Business on the Fundamental Change Repurchase Date corresponding to such Fundamental Change, shall
be increased to an amount equal to the Conversion Rate that would, but for this Section 10.15, otherwise apply to such Security
pursuant to this Article 10, plus an amount equal to the Make-Whole Applicable Increase.

 

(b)          As
used herein, “Make-Whole Applicable Increase” shall mean, with respect to a Make-Whole Fundamental Change, the
amount, set forth in the following table, which corresponds to the Effective Date and the Applicable Price of such Make-Whole Fundamental
Change:

provided, however,
that:

 

(i)          if
the actual Applicable Price of such Make-Whole Fundamental Change is between two (2) Applicable Prices listed in the table above
in the row immediately below the title “Applicable Price” or if the actual Effective Date of such Make-Whole Fundamental
Change is between two Effective Dates listed in the table under the column titled “Effective Date”, then the Make-Whole
Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Make-Whole Applicable
Increases set forth for such higher and lower Applicable Prices, or for such earlier and later Effective Dates based on a three
hundred and sixty five (365) or three hundred and sixty six (366) day year, as applicable;

 

(ii)         if
the actual Applicable Price of such Make-Whole Fundamental Change is greater than $26.00 per share (subject to adjustment in the
same manner as the Applicable Prices pursuant to Section 10.15(b)(iii)), or if the actual Applicable Price of such Make-Whole Fundamental
Change is less than $6.50 per share (subject to adjustment in the same manner as the Applicable Prices pursuant to Section 10.15(b)(iii)),
then the Make-Whole Applicable Increase shall be equal to zero (0);

 

(iii)        if
an event occurs that requires, pursuant to this Article 10 (other than solely pursuant to this Section 10.15), an adjustment to
the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each Applicable Price set forth
in the table above under the title “Applicable Price” shall be deemed to be adjusted so that such Applicable Price,
at and after such time, shall be equal to the product of (A) such Applicable Price as in effect immediately before such adjustment
to such Applicable Price and (B) a fraction the numerator of which is the Conversion Rate in effect immediately before such adjustment
to the Conversion Rate and the denominator of which is the Conversion Rate to be in effect, in accordance with this Article 10,
immediately after such adjustment to the Conversion Rate;

 

(iv)        each
Make-Whole Applicable Increase amount set forth in the table above shall be adjusted in the same manner, for the same events and
at the same time as the Conversion Rate is required to be adjusted pursuant to Section 10.06 through Section 10.14; and

 

(v)         in
no event shall the Conversion Rate applicable to any Security be increased pursuant to this Section 10.15 to the extent, but only
to the extent, such increase shall cause the Conversion Rate applicable to such Security to exceed 153.8461 shares per $1,000 principal
amount (the “Maximum Conversion Rate”); provided, however, that the Maximum Conversion Rate shall
be adjusted at the same time and in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted
pursuant to this Article 10.

 

(c)          Subject
to Section 10.12, upon surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, the Company shall
satisfy its conversion obligation by delivering shares of Common Stock (together with cash in lieu of any fractional share) in
accordance with Section 10.02; provided, however, that if at the effective time of a Make-Whole Fundamental Change
described in clause (c) of the definition of Change in Control the consideration for the Common Stock is composed entirely of cash,
for any conversion of Securities following the Effective Date of such Make-Whole Fundamental Change, the conversion obligation
shall be calculated based solely on the Applicable Price for the transaction and shall be deemed to be an amount equal to, per
$1,000 principal amount of converted Securities, the Conversion Rate (including any Make-Whole Applicable Increase), multiplied
by such Applicable Price.

 

    	-54-

    	 

    

 

(d)          As
used herein, “Applicable Price” shall have the following meaning with respect to a Make-Whole Fundamental Change:
(i) if such Make-Whole Fundamental Change is a transaction or series of transaction described in clause (c) of the definition of
Change in Control and the consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights)
for shares of the Common Stock in such Make-Whole Fundamental Change consists solely of cash, then the “Applicable Price”
with respect to such Make-Whole Fundamental Change shall be equal to the cash amount paid per share of Common Stock in such Make-Whole
Fundamental Change and (ii) in all other circumstances, the “Applicable Price” with respect to such Make-Whole Fundamental
Change shall be equal to the average of the Closing Sale Prices per share of Common Stock for the five (5) consecutive Trading
Days immediately preceding, but excluding, the Effective Date of such Make-Whole Fundamental Change, which average shall be appropriately
adjusted by the Board of Directors, in its good faith determination, to account for any adjustment, pursuant hereto, to the Conversion
Rate that shall become effective, or any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the record
date of such event occurs, at any time during such five (5) consecutive Trading Days.

 

(e)          The
Company shall deliver to each Holder, in accordance with Section 13.01, written notice of the Effective Date of the Make-Whole
Fundamental Change within ten (10) days of such Effective Date. Each such notice shall also state that, in connection with such
Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Securities
entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods
during which Securities must be surrendered in order to be entitled to such increase, including, without limitation, the last day
of the Make-Whole Conversion Period).

 

(f)          For
avoidance of doubt, the provisions of this Section 10.15 shall not affect or diminish the Company’s obligations, if any,
pursuant to Article 3 with respect to a Make-Whole Fundamental Change that also constitutes a Fundamental Change.

 

(g)          Nothing
in this Section 10.15 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.06 in respect of a Make-Whole Fundamental
Change.

Article
11

Concerning the Holders

 

Section 11.01. Action
by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount
of the Securities may take any action (including the making of any demand or request, the giving of any notice, consent or waiver
or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage
have joined therein may be evidenced (i) by any instrument or any number of instruments of similar tenor executed by Holders in
person or by agent or proxy appointed in writing, (ii) by the record of the Holders voting in favor thereof at any meeting of Holders
duly called and held in accordance with the provisions of Article 12, (iii) by a combination of such instrument or instruments
and any such record of such a meeting of Holders, or (iv) in the case of a Global Security, in accordance with the procedures of
the Depositary. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Securities, the Company
or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining
Holders entitled to take such action. The record date if one is selected shall be not more than fifteen (15) days prior to the
date of commencement of solicitation of such action.

 

Section 11.02. Proof
of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and Section 12.05, proof of the execution
of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations
as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Securities shall
be proved by the security register of the Registrar or by a certificate of the Registrar. The record of any Holders’ meeting
shall be proved in the manner provided in Section 12.06.

 

Section 11.03. Persons
Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any
Registrar may deem the Person in whose name a Security shall be registered upon the security register of the Registrar to be, and
may treat it as, the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation
of ownership or other writing thereon made by any Person other than the Company or any Registrar) for the purpose of receiving
payment of or on account of the principal of and (subject to Section 2.12 and Section 4.01) accrued and unpaid interest on such

of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Securities
held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting
of Holders duly called pursuant to the provisions of Section 12.02 or Section 12.03 may be adjourned from time to time by the Holders
of a majority of the aggregate principal amount of Securities represented at the meeting, whether or not constituting a quorum,
and the meeting may be held as so adjourned without further notice.

for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate
of all votes cast at the meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote
by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice
of the meeting and showing that said notice was delivered as provided in Section 12.02. The record shall show the principal amount
of the Securities voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

 

Any record so signed

1.          Interest.
Emerald Oil, Inc., a Montana corporation (the “Company”), promises to pay interest on the principal amount of
this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on April
1 and October 1 of each year, with the first payment to be made on October 1, 2014. Interest on the Securities will accrue on the
principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has
been paid, from, and including, March 24, 2014, in each case to, but excluding, the next Interest Payment Date or the Maturity
Date, as the case may be. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay,
in cash, interest on any overdue amount (including, to the extent permitted by applicable law, overdue interest) at the rate provided
for in Section 2.12. of the Indenture (as defined below). In certain circumstances, Additional Interest will be payable in accordance
with Section 4.09(a), Section 4.09(b) and Section 6.02(b) of the Indenture and any reference to “interest” shall be
deemed to include any such Additional Interest.

 

2.          Maturity.
The Securities will mature on April 1, 2019.

 

3.          Method
of Payment. Except as provided in the Indenture, the Company will pay interest on the Securities to the Persons who are Holders
of record of Securities at the Close of Business on the Record Date set forth on the face of this Security immediately preceding
the applicable Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect the principal amount plus,
if applicable, accrued and unpaid interest, if any, or the Fundamental Change Repurchase Price, payable as herein provided on the
Maturity Date or Fundamental Change Repurchase Date, as applicable.

 

4.          Paying
Agent, Registrar, Conversion Agent. Initially, U.S. Bank National Association (the “Trustee”) will act as
Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without prior
notice.

 

5.          Indenture.
The Company issued the Securities under an Indenture dated as of March 24, 2014 (the “Indenture”) between the
Company and the Trustee. The Securities are subject to all terms set forth in the Indenture, and Holders are referred to the Indenture
for a statement of such terms. The Securities are unsecured senior obligations of the Company. Terms used herein without definition
and which are defined in the Indenture have the meanings assigned to them in the Indenture. In the event of any inconsistency between
the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control.

 

6.          No
Redemption. The Securities are not redeemable at the option of the Company prior to the Maturity Date, and no sinking fund
is provided for the Securities.

 

    	4

    	 

    

 

7.          Repurchase
at Option of Holder Upon a Fundamental Change. Subject to the terms and conditions of the Indenture, in the event of a Fundamental
Change, each Holder of the Securities shall have the right, at the Holder’s option, to require the Company to repurchase
such Holder’s Securities including any portion thereof which is $1,000 in principal amount or any integral multiple thereof
on the Fundamental Change Repurchase Date at a price payable in cash equal to the Fundamental Change Repurchase Price.

 

8.          Conversion.
The Securities shall be convertible into shares of Common Stock in accordance with Article 10 of the Indenture. To convert a Security,
a Holder must satisfy the requirements of Section 10.02(a) of the Indenture. A Holder may convert a portion of a Security if the
portion is $1,000 principal amount or an integral multiple of $1,000 principal amount.

 

Upon conversion of
a Security, the Holder thereof shall be entitled to receive the shares of Common Stock payable upon conversion in accordance with
Article 10 of the Indenture, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the
Indenture.

 

9.          Denominations,
Transfer, Exchange. The Securities are in registered form, without coupons, in denominations of $1,000 principal amount and
integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as
provided in the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer
documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment
of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in connection with certain transfers
or exchanges as set forth in the Indenture. The Company or the Trustee, as the case may be, shall not be required to register the
transfer or exchange of any Security which a Repurchase Notice has been delivered, and not withdrawn, in accordance with the Indenture,
except the unrepurchased portion of Securities being repurchased in part.

 

10.         Persons
Deemed Owners. The registered Holder of a Security will be treated as its owner for all purposes. Only registered Holders of
Securities shall have the rights under the Indenture.

 

11.         Amendments,
Supplements and Waivers. The Indenture contains provisions permitting the Company and the Trustee in certain circumstances,
without the consent of the Holders of the Securities, and in certain other circumstances, with the consent of the Holders of at
least a majority in aggregate principal amount of the outstanding Securities, to amend or supplement the Indenture or the Securities.

 

12.         Defaults
and Remedies. Subject to certain exceptions, if an Event of Default occurs and is continuing, the Trustee by notice to the
Company or the Holders of at least twenty five percent (25%) in principal amount of the Securities then outstanding by notice to
the Company and the Trustee may declare the principal of, and any accrued and unpaid interest on, all Securities to be due and
payable immediately. If any of certain bankruptcy or insolvency-related Events of Default occurs and is continuing, the principal
of, and accrued and unpaid interest on, all the Securities shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder. Subject to certain exceptions, the Holders of a majority
in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may rescind or annul an acceleration
and its consequences if certain conditions specified in the Indenture are satisfied.

in its individual or any other capacity, may make loans to, accept deposits from, and perform services for, the Company or its
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.

 

14.         Authentication.
This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent in accordance
with the Indenture.

 

15.         Abbreviations.
