In any case where several matters are required

Section 1.4 Acts of Holders; Record Dates.

 

Any request, demand, authorization, direction,
notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied
in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed
in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the Company. The Trustee shall promptly deliver to
the Company copies of all such instrument or instruments delivered to the Trustee. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument
or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

 

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

 

The ownership of Securities shall be proved
by the Security Register.

 

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

 

    8

     

    

 

The Company may set any day as a record
date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request,
demand, authorization, direction, vote, notice, consent, waiver or other action provided or permitted by this Indenture to be given,
made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction
referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities
of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not
such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken
on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series
on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any
action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series
on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee
in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6.

 

The Trustee may set any day as a
record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.2, (iii) any request to
institute proceedings referred to in Section 5.7(2) or (iv) any direction referred to in Section 5.12, in each case with
respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration,
request or direction, whether or not such Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent
the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of
no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the
requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after
any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to
each Holder of Securities of the relevant series in the manner set forth in Section 1.6.

 

With respect to any record date set pursuant
to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from
time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective
unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities
of the relevant series in the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall
be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject
to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall
be later than the 180th day after the applicable record date.

 

Without limiting the foregoing, a Holder
entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part
of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

 

Section 1.5 Notices, etc., to Trustee
and Company.

 

Any request, demand, authorization, direction,
notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished
to, or filed with,

 

(1)              
the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or
filed in writing and delivered in person or mailed by first-class mail (registered or certified, return receipt requested), email
or other electronic methods, or overnight air courier guaranteeing next day delivery, (or by facsimile transmissions, provided
that oral confirmation of receipt shall have been received) to or with the Trustee at its Corporate Trust Office, Attention: Omeros
Corporation Administrator, or

 

    9

     

    

 

(2)              
the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, personally delivered or sent via overnight courier to the Company
addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address
previously furnished in writing to the Trustee by the Company, Attention: Chief Financial Officer.

 

(3)               the
Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf,
facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received
an incumbency certificate listing Persons designated to give such instructions or directions and containing specimen
signatures of such designated persons, which incumbency certificate shall be amended and replaced whenever a Person is to be
added or deleted from the listing. If the Company elects to give the Trustee e-mail or facsimile instructions (or
instructions by a similar electronic method), the Trustee’s understanding of such instructions shall be deemed
controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the
Trustee’s reliance upon and compliance with such instructions notwithstanding that such instructions may conflict or
are inconsistent with a subsequent written instruction. The Company agrees to assume all risks arising out of the use of such
electronic methods to submit instructions and directions to the Trustee, including the risk of the Trustee acting on
unauthorized instructions, and the risk of interception and misuse by third parties.

 

Section 1.6 Notice to Holders; Waiver.

 

Where this Indenture provides for notice
to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and
mailed, first-class postage prepaid, or delivered by hand or overnight courier to each Holder affected by such event, at its address
as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice; provided, however, that notices given to Holders of any Global Note may
be given through the facilities of the Depositary therefor (and notice provided in such manner will be deemed to be “written”
notice and to satisfy any requirement in this Indenture or the Notes to “mail” notice to the applicable Holder). Neither
the failure to mail or deliver by hand or overnight courier any notice, nor any defect in any notice so mailed or delivered by
hand or overnight courier, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.
Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance
upon such waiver.

 

In case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall
be made as acceptable to the Trustee shall constitute a sufficient notification for every purpose hereunder.

 

Section 1.7 Conflict with Trust Indenture
Act.

 

If any provision hereof limits, qualifies
or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern
this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the
Trust Indenture Act, which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or to be excluded, as the case may be.

Redemption Date or Stated Maturity of any Security or the last date on which a Holder has the right to convert a Security at a

Section 3.3 Execution, Authentication,
Delivery and Dating.

 

The Securities shall be executed on behalf
of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief Executive Officer, its principal financial
officer, its President or one of its Vice Presidents, attested by its Treasurer, its Secretary or one of its Assistant Treasurers
or Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile.

 

Securities bearing the manual or facsimile
signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that
such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

 

At any time and from time to time after
the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee
for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have
been established by or pursuant to one or more Board Resolutions as permitted by Section 2.1 and Section 3.1, in authenticating
such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee
shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying upon, a copy of such Board Resolution,
the Officers’ Certificate setting forth the terms of the series and an Opinion of Counsel, with such Opinion of Counsel stating,

 

(1)              
if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.1, that
such form has been established in conformity with the provisions of this Indenture;

 

(2)              
if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.1, that
such terms have been established in conformity with the provisions of this Indenture; and

 

    23

     

    

 

 

(3)              
 that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject
to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable
in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar
laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

 

If such form or terms have been so established,
the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will
affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee.

 

Notwithstanding the provisions of Section
3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be
necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion
of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series
if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to
be issued.

 

Each Security shall be dated the date of
its authentication.

 

No Security shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication
substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security
shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9, for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture.

 

Neither the Company nor the Trustee shall
have any responsibility for any defect in the CUSIP number that appears on any Security, check, advice of payment or redemption
notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service
for convenience of reference and that neither the Company nor the Trustee shall be liable for any inaccuracy in such numbers.

 

The Trustee shall not have any responsibility
for any acts or failures to act by the Depositary.

 

Section 3.4 Temporary Securities.

 

Pending the preparation of definitive
Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

 

    24

     

    

 

If temporary Securities of any series are
issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation
of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities
of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment
for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series,
the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities
of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of
such series and tenor.

 

Section 3.5 Registration; Registration
of Transfer and Exchange.

 

The Company shall cause to be kept at the
Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the
Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities
and transfers of Securities as herein provided.

 

Upon surrender for registration of transfer
of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities
of the same series, of any authorized denominations and of like tenor and aggregate principal amount.

 

At the option of the Holder, Securities
of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate
principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making
the exchange is entitled to receive.

 

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

 

Every Security presented or surrendered
for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied
by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder
thereof or its attorney duly authorized in writing.

 

    25

     

    

 

No service charge shall be made for any
registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, Section 9.6 or Section 11.7 not involving any transfer.

 

If the Securities of any series (or of any
series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of
or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning
at the opening of business 15 days before the day of the sending of a notice of redemption of any such Securities selected for
redemption under Section 11.3 and ending at the close of business on the day of such mailing or electronic transmission, or (B)
to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion
of any Security being redeemed in part.

 

The provisions of clauses (1), (2), (3)
and (4) below shall apply only to Global Securities:

 

(1)              
Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for
such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each
such Global Security shall constitute a single Security for all purposes of this Indenture.

 

(2)              
Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities
registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling
or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange
Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) there shall
exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated
by Section 3.1.

 

(3)              
Subject to clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and
all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary
for such Global Security shall direct.

 

(4)              
Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global
Security or any portion thereof, whether pursuant to this Section, Section 3.4, Section 3.6, Section 9.6 or Section 11.7 or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the
name of a Person other than the Depositary for such Global Security or a nominee thereof.

 

(5)              
Notwithstanding anything herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible for ascertaining
whether any transfer complies with the registration provisions of or exemptions from the Securities Act, applicable state securities
laws or other applicable federal or state laws.

 

    26

     

    

 

Section 3.6 Mutilated, Destroyed,
Lost and Stolen Securities.

 

If any mutilated Security is surrendered
to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of
the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

 

If there shall be delivered to the Company
and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or
indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice
to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the
Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series
and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

 

In case any such mutilated, destroyed, lost
or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new
Security, pay such Security.

 

Upon the issuance of any new Security under
this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

 

Every new Security of any series issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series
duly issued hereunder.

 

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

 

Section 3.7 Payment of Interest; Interest
Rights Preserved.

 

Except as otherwise provided as contemplated
by Section 3.1 with respect to any series of Securities or in a supplemental indenture with respect to any series of Securities,
interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest.

 

    27

     

    

 

Any interest on any Security of any series
which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been
such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or
(2) below:

 

(1)              
 The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series
(or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect
of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in
this clause provided. Thereupon the Company shall fix a Special Record Date for the payment of such Defaulted Interest, which shall
be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section
1.6, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities
of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (2).

 

(2)              
The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner
of payment shall be deemed practicable by the Trustee.

 

Subject to the foregoing provisions of this
Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other
Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

 

Section 3.8 Persons Deemed Owners.

 

Prior to due presentment of a Security for
registration of transfer or exchange or at maturity, the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal
of and any premium and (subject to Section 3.7) any interest on such Security and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected
by notice to the contrary.

 

    28

     

    

 

Section 3.9 Cancellation.

 

All Securities surrendered for payment,
redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired
in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall
be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled
as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall
be disposed of in accordance with its customary procedures.

 

Section 3.10 Computation of Interest.

 

Except as otherwise specified as contemplated
by Section 3.1 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day
year of twelve 30-day months.

Section 5.2 Acceleration of
Maturity; Rescission and Annulment.

 

Unless the Board Resolution, supplemental
indenture or Officers’ Certificate establishing such series provides otherwise, if an Event of Default (other than an Event
of Default specified in Section 5.1(5) or Section 5.1(6)) with respect to Securities of any series at the time Outstanding occurs
and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities
of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified
by the terms thereof), and premium, if any, together with accrued and unpaid interest, if any, thereon, to be due and payable immediately,
by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal
amount (or specified amount), and premium, if any, together with accrued and unpaid interest, if any, thereon, shall become immediately
due and payable. If an Event of Default specified in Section 5.1(5) or Section 5.1(6)) with respect to Securities of any series
at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series
are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms
thereof), and premium, if any, together with accrued and unpaid interest, if any, thereon, shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.

 

At any time after such a declaration of
acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due
has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if

 

(1)              
the Company has paid or deposited with the Trustee a sum sufficient to pay

 

		(A)	all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel;

 

		(B)	all overdue interest on all Securities of that series,

 

		(C)	the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration
of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, and

 

		(D)	to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor
in such Securities.

 

(2)              
all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities
of that series that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section
5.13.

 

    32

     

    

 

No such rescission shall affect any subsequent
default or impair any right consequent thereon.

 

Section 5.3 Collection of Indebtedness
and Suits for Enforcement by Trustee.

 

The Company covenants that if

 

(1)              
default is made in the payment of any interest on any Security when such interest becomes due and payable and such default
continues for a period of 30 days, or

 

(2)              
default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, the Company
will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor
in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 

If an Event of Default with respect to Securities
of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights
of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper remedy.

 

Section 5.4 Trustee May File Proofs of
Claim.

 

In case of any judicial proceeding relative
to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered,
by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order
to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to
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 other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to 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 6.7.

 

No provision of this Indenture 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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a
member of a creditors’ or other similar committee.

 

    33

     

    

 

Section 5.5 Trustee May Enforce Claims
Without Possession of Securities.

 

All rights of action and claims under this
Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the
production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Securities in respect of which such judgment has been recovered.

 

Section 5.6 Application of Money Collected.

 

Any money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution
of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon
of the payment if only partially paid and upon surrender thereof if fully paid:

 

FIRST: To the payment of all amounts due
the Trustee under Section 6.7;

 

SECOND: To the payment of the amounts then
due and unpaid for principal of and any premium, if any, and interest on the Securities in respect of which or for the benefit
of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable
on such Securities for principal and any premium, if any, and interest, respectively; and

 

THIRD: The balance, if any, to the Company
or any other Person or Persons entitled thereto.

 

Section 5.7 Limitation on Suits.

 

No Holder of any Security of any series
shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment
of a receiver or trustee, or for any other remedy hereunder, unless

 

(1)              
such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities
of that series;

 

(2)              
the Holders of at least 25% in aggregate principal amount of the Outstanding Securities of that series shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

 

(3)              
such Holder or Holders have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs,
expenses, losses and liabilities to be incurred in compliance with such request;

 

    34

     

    

 

(4)              
 the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such
proceeding; and

 

(5)              
no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders
of a majority in principal amount of the Outstanding Securities of that series;

 

it being understood and intended that no one or more of such
Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture (it being understood that the Trustee shall not have an affirmative
duty to ascertain whether or not any such direction is unduly prejudicial to any other Holder), except in the manner herein provided
and for the equal and ratable benefit of all of such Holders.

 

Section 5.8 Unconditional Right of Holders
to Receive Principal, Premium and Interest and to Convert.

 

Notwithstanding any other provision in this
Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal
of and any premium and (subject to Section 3.7) interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), to convert such Securities in accordance with Article 14 to the
extent that such right to convert is applicable to such Security, and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

 

Section 5.9 Restoration of Rights and
Remedies.

 

If the Trustee or any Holder has instituted
any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination
in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had
been instituted.

 

Section 5.10 Rights and Remedies Cumulative.

 

Except as otherwise provided with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right
or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

 

    35

     

    

 

Section 5.11 Delay or Omission Not
Waiver.

 

No delay or omission of the Trustee or of
any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or
remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the
Trustee (subject to the limitations contained in this Indenture) or by the Holders, as the case may be.

 

Section 5.12 Control by Holders.

 

The Holders of a majority in principal amount
of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities
of such series, provided that such direction shall not be in conflict with any rule of law or with this Indenture and the Trustee
shall not have determined that the action so directed would be unjustly prejudicial to Holders of Securities of that series, or
any other series, not taking part in such direction; and the Trustee may take any other action deemed proper by the Trustee that
is not inconsistent with such direction or this Indenture.

 

Section 5.13 Waiver of Past Defaults.

 

The Holders of not less than a majority
in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series
waive any past default hereunder with respect to such series and its consequences, except

 

(1)              
a default in the payment of the principal of or any premium or interest on any Security of such series as and when the same
shall become due and payable by the terms thereof, otherwise than by acceleration (unless such default has been cured and a sum
sufficient to pay all matured installments of interest, principal and premium, if any, has been deposited with the Trustee), or

 

(2)              
to the extent such right is applicable to such Security, a failure by the Company on request to convert any Security into
Common Stock; or

 

(3)              
in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of
the Holder of each Outstanding Security of such series affected.

 

Upon any such waiver, such default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

 

Section 5.14 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, suffered or omitted by it as
Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided
that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking
or to make such an assessment in any suit instituted by the Company or in any suit for the enforcement of the right to
convert any Security in accordance with Article 14.

 

    36

     

    

 

Section 5.15 Waiver of Usury, Stay or
Extension Laws.

 

The Company covenants (to the extent that
it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit
or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 

Article

THE TRUSTEE

 

Section 6.1 Certain Duties and Responsibilities.

 

The Trustee, prior to the occurrence of
an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Indenture .and no implied covenants or obligations shall be read
into this Indenture against the Trustee. In the event an Event of Default has occurred, is continuing and is known to a Responsible
Officer, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care
and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs.

 

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

Section 6.4 Not Responsible for Recitals
or Issuance of Securities.

 

The recitals contained herein and in the
Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither
the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations
as to the validity, sufficiency or priority of this Indenture or of the Securities. Neither the Trustee nor any Authenticating
Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.

 

Section 6.5 May Hold Securities and Act
as Trustee under Other Indentures.

 

The Trustee, any Authenticating Agent, any
Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the
owner or pledgee of Securities and, subject to Section 6.8 and Section 6.13, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

 

Subject to the limitations imposed by the
Trust Indenture Act, nothing in this Indenture shall prohibit the Trustee from becoming and acting as trustee under other indentures
under which other securities, or certificates of interest of participation in other securities, of the Company are outstanding
in the same manner as if it were not Trustee hereunder.

 

Section 6.6 Money Held in Trust.

 

Money held by the Trustee in trust hereunder
need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest
on any money received by it hereunder except as otherwise agreed with the Company.

 

Section 6.7 Compensation and Reimbursement.

 

The Company agrees:

 

(1)              
to pay to the Trustee from time to time as shall be agreed to in writing between the Company
and the Trustee reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express trust);

 

(2)              
except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation
and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable
to its willful misconduct or negligence as adjudicated by a court of competent jurisdiction; and

 

    41

     

    

 

(3)              
 to indemnify the Trustee or any predecessor Trustee in any capacity under this Indenture and any other document or transaction
entered into in connection herewith and their agents and any authentication agent for, and to hold it harmless against, any loss,
claim (whether asserted by the Company, any Holder or any other Person), damage, liability or expense incurred without negligence
or willful misconduct (as finally adjudicated by a court of competent jurisdiction) on the part of the Trustee, its officers, directors,
agents or employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance
or administration of this trust or in any other capacity hereunder, and the performance of its duties hereunder or the exercise
of its rights and powers, including the costs and expenses (including reasonable attorneys’ fees and expenses and court costs)
of defending itself against any action, claim or liability or suit brought to enforce the Trustee’s right to indemnification
in connection with the exercise or performance of any of its powers or duties hereunder. The obligations of the Company under this
Section 6.7 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances
shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by
the Trustee, except, subject to the effect of Section 5.6, funds held in trust herewith for the benefit of the Holders of particular
Notes. The Trustee’s right to receive payment of any amounts due under this Section 6.7 shall not be subordinate to any other
liability or indebtedness of the Company. The obligation of the Company under this Section 6.7 shall survive the satisfaction and
discharge of this Indenture and the earlier resignation or removal of the Trustee. The indemnification provided in this Section
6.7 shall extend to the officers, directors, agents and employees of the Trustee.

 

When the Trustee incurs expenses or renders
services after an Event of Default specified in Section 5.1(5) or Section 5.1(6) hereof occurs, the expenses and the compensation
for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration
under any applicable bankruptcy, insolvency, reorganization or similar law.

 

Section 6.8 Conflicting Interests.

 

If the Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act and there is an Event of Default under the Securities of that series, the
Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions
of, the Trust Indenture Act and this Indenture. To the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed
to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series.

 

Section 6.9 Corporate Trustee Required;
Eligibility.

 

There shall at all times be one (and
only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of
one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such
and has (or if the Trustee is a member of a bank holding company system, its bank holding company has) a combined capital and
surplus of at least $50,000,000. If any such Person or bank holding company publishes reports of condition at least annually,
pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and
to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person or bank holding company
shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If
at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this
Article.

 

The Trustee shall have no responsibility
or liability for the action or inaction of a successor trustee.

 

    42

     

    

 

Section 6.10 Resignation and Removal;
Appointment of Successor.

and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by
the successor Trustee in accordance with the applicable requirements of Section 6.11.

 

The Trustee may resign at any time with
respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance
by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

 

The Trustee may be removed at any time with
respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series, delivered to the Trustee and to the Company.

 

If at any time:

 

(1)              
the Trustee shall fail to comply with Section 6.8 after written request therefor by the Company or by any Holder who has
been a bona fide Holder of a Security for at least six months, or

 

(2)              
the Trustee shall cease to be eligible under Section 6.9 and shall fail to resign after written request therefor by the
Company or by any such Holder, or

 

(3)              
the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or
of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs
for the purpose of rehabilitation, conservation or liquidation,

 

then, in any such case, (A) the Company by a Board Resolution
may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who has been a bona fide Holder
of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

 

    43

     

    

 

If the Trustee shall resign, be removed
or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities
of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to
the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities
of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within 45 days after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment
in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to
the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.11, the retiring Trustee may petition, or any Holder who has been a bona fide Holder of a Security of such
series for at least six months may petition, on behalf of himself and all others similarly situated, any court of competent jurisdiction
for the appointment of a successor Trustee with respect to the Securities of such series.

 

The Company shall give notice of each resignation
and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect
to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.6. Each notice
shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate
Trust Office.

 

Section 6.11 Acceptance of Appointment
by Successor.

 

In case of the appointment hereunder of
a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of
the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

 

    44

     

    

 

In case of the appointment hereunder
of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee
and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental or other instrument hereto wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee
all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by
more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such
Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate
and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture or other instrument the resignation or removal of the retiring Trustee shall become effective to
the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested
with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such
retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor
Trustee relates.

 

Upon request of any such successor Trustee,
the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee
all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

 

No successor Trustee shall accept its appointment
unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

 

Section 6.12 Merger, Conversion, Consolidation
or Succession to Business.

 

Any corporation into which the Trustee may
be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation
to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of
the Trustee (including the administration of the trust created by this Indenture), shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any
paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities. In the event that any Securities shall not have been authenticated by such predecessor Trustee,
any such successor Trustee may authenticate and deliver such Securities in either its own name or that of such predecessor Trustee,
with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee.

 

    45

     

    

 

Section 6.13 Preferential
Collection of Claims Against Company.

 

If and when the Trustee shall be or become
a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of claims against the Company (or any such other obligor).

 

Section 6.14 Appointment of Authenticating
Agent.

 

The Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of, subject to the
direction of the Trustee, to authenticate and deliver Securities of such series issued upon original issue and upon exchange, registration
of transfer or partial redemption thereof or pursuant to Section 3.6, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever
reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate
of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent
shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having
(or if the Authenticating Agent is a member of a bank holding company system, its bank holding company has) a combined capital
and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

 

Any corporation into which an Authenticating
Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall
be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

 

An Authenticating Agent may resign at
any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency
of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which
shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.6 to all
Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

 

    46

     

    

 

The Company agrees to pay to each Authenticating
Agent from time to time reasonable compensation for its services under this Section.

 

If an appointment with respect to one or
more series is made pursuant to this Section 6.12, the Securities of such series may have endorsed thereon, in lieu of the Trustee’s
certificate of authentication, an alternative certificate of authentication in the following form:

 

This is one of the Securities of the series
designated therein referred to in the within-mentioned Indenture.

A supplemental indenture which changes or
eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or
more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of
any other series.

 

It shall not be necessary for any Act of
Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such Act shall approve the substance thereof.

COVENANTS

 

Section 10.1 Payment of Principal, Premium
and Interest.

Section 10.2 Maintenance of Office or
Agency.

 

The Company will maintain in each Place
of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that
series may be surrendered for conversion and where notices and demands to or upon the Company in respect of the Securities of that

The Company may also from time to time designate
one or more other offices or agencies where the Securities of one or more series 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 each Place of Payment for Securities of
any series 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.

 

Section 10.3 Money for Securities Payments
to be Held in Trust.

 

If the Company shall at any time act
as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or
any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be
paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

Whenever the Company shall have one or more

on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided
by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

 

The Company will cause each Paying Agent
for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions
of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or
any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series,
upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

 

The Company may at any time, for the purpose
of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon
the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying
Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

of or any premium or interest on any Security of any series and remaining unclaimed for a period ending on the earlier of the date
that is ten Business Days prior to the date such money would escheat to the State or two years after such principal, premium or
interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

 

Section 10.4 Statement by Officers as
to Default.

 

The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’
Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance
and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the
nature and status thereof of which they may have knowledge. The fiscal year of the Company currently ends on December 31; and

instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.1(19), Section
9.1(2) or Section 9.1(7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend
to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

 

Article

REDEMPTION OF SECURITIES

 

Section 11.1 Applicability of Article.

 

Securities of any series that are redeemable
before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated
by Section 3.1 for such Securities) in accordance with this Article.

 

Section 11.2 Election to Redeem; Notice
to Trustee.

 

The election of the Company to redeem any
Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 3.1 for such Securities.
In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption
affecting only a single Security), the Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless
a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of
Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance
with such restriction.

 

    55

     

    

 

Section 11.3 Selection by Trustee
of Securities to Be Redeemed.

 

If less than all the Securities of any series
are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption
affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by lot in
accordance with the applicable procedures of the Depositary, or on a pro-rata basis, provided that the unredeemed portion of the
principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination)
for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption
in accordance with the preceding sentence.

 

If any Security selected for partial redemption
is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted
portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities that have been
converted during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such
selection.

 

The Trustee shall promptly notify the Company
in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption
as aforesaid, the principal amount thereof to be redeemed.

 

The provisions of the two preceding paragraphs
shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole
or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be
in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security.

 

For all purposes of this Indenture, unless
the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities
redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

 

Section 11.4 Notice of Redemption.

 

Notice of redemption shall be given by first-class
mail, postage prepaid, or electronically sent not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter
period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address appearing in
the Security Register.

 

All notices of redemption shall state:

 

(1)           
the Redemption Date,

 

(2)           
the Redemption Price (including accrued interest, if any),

 

    56

     

    

 

(3)           
 if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed,
the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities
to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed,
the principal amount of the particular Security to be redeemed,

 

(4)           
in case any Security is to be redeemed in part only, that on and after the Redemption Date, upon surrender of such Security,
the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal
amount thereof remaining unredeemed,

 

(5)           
that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and,
if applicable, that interest thereon will cease to accrue on and after said date,

 

(6)           
the place or places where each such Security is to be surrendered for payment of the Redemption Price,

 

(7)           
if applicable, the conversion price or the conversion rate, as the case may be, the date on which the right to convert the
principal of the Securities or the portions thereof to be redeemed will terminate, and the place or places where such Securities
may be surrendered for conversion,

 

(8)           
that the redemption is for a sinking fund, if such is the case, and

 

(9)           
the CUSIP number or numbers and/or common codes of the Security being redeemed; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any
notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and
any such redemption shall not be affected by any defect in or omission of such numbers.

 

Notice of redemption of Securities to be
redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the
name and at the expense of the Company and shall be irrevocable.

 

Section 11.5 Deposit of Redemption Price.

 

On or prior to any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 10.3) an amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date, in which case interest shall be deposited in accordance with Section 3.7) accrued
interest on, all the Securities which are to be redeemed on that date.

 

If any Security called for redemption
is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the
redemption of such Security shall (subject to the right of any Holder of such Security to receive interest as provided in the
last paragraph of Section 3.7) be paid to the Company on Company Request, or if then held by the Company, shall be discharged
from such trust.

 

    57

     

    

 

Section 11.6 Securities Payable on Redemption
Date.

 

Notice of redemption having been given as
aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein
specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest)
such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice,
such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided,
however, that, unless otherwise specified as contemplated by Section 3.1, installments of interest whose Stated Maturity is on
or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered
as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.7.

 

If any Security called for redemption shall
not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption
Date at the rate prescribed therefor in the Security.

 

Section 11.7 Securities Redeemed in Part.

 

Any Security which is to be redeemed only
in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by,
or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or
its attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of
the principal of the Security so surrendered.

The Company may elect, at its option at
any time, to have Section 13.2 or Section 13.3 applied to any Securities or any series of Securities, as the case may be, designated
pursuant to Section 3.1 as being defeasible pursuant to such Section 13.2 or Section 13.3, in accordance with any applicable requirements

Section 13.2 Defeasance and Discharge.

 

Upon the Company’s exercise of
its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated
or discharged hereunder:

 

(1)           
the rights of Holders of such Securities to receive, solely from the trust fund described in Section 13.4 and as more fully
set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments
are due,

 

(2)           
the Company’s obligations with respect to such Securities under Section 3.4, Section 3.5, Section 3.6, Section 10.2
and Section 10.3, and, if applicable, Article 14,

 

(3)           
the rights, powers, trusts, duties and immunities of the Trustee hereunder, and

 

(4)           
this Article.

 

Subject to compliance with this Article,
the Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the prior exercise
of its option (if any) to have Section 13.3 applied to such Securities.

 

Section 13.3 Covenant Defeasance.

 

Upon the Company’s exercise of its
option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be,

 

(1)           
the Company shall be released from its obligations under any covenants provided pursuant to Section 3.1(19), Section 9.1(2)
or Section 9.1(7) for the benefit of the Holders of such Securities and

 

(2)           
the occurrence of any event specified in Section 5.1(4) (with respect to any such covenants provided pursuant to Section
3.1(19), Section 9.1(2) or Section 9.1(7)) and the occurrence of any other Event of Default specified pursuant to Section 3.1 shall
be deemed not to be or result in an Event of Default, in each case with respect to such Securities or any series of Securities
as provided in this Section on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter called “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit
to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section
(to the extent so specified in the case of Section 5.1(4) and the occurrence of any Event of Default specified pursuant to Section
3.1), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference
in any such Section to any other provision herein or in any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.

 

    60

     

    

 

Section 13.4 Conditions to Defeasance
or Covenant Defeasance.

the application of Section 13.2 or Section 13.3 to any Securities or any series of Securities, as the case may be:

funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to,
the benefits of the Holders of such Securities,

firm of independent public accountants, investment bankers or appraisers expressed in a written certification thereof delivered
to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and
discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance
with the terms of this Indenture and such Securities.

 

(2)

		(B)	since the date of this instrument, there has been a change in the applicable Federal income tax law,

 

    61

     

    

 

in either case (A) or (B) to the effect that, and based thereon
such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes
as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal
income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge
were not to occur.

 

(3)           
For Securities denominated in United States dollars, in the event of an election to have Section 13.3 apply to any Securities
or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect

The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither such Securities
nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit.

that this condition shall not be deemed satisfied until after such 90th day).

 

(6)           
Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of
the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act).

 

(7)           
Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this
Indenture or any other agreement or instrument to which the Company is a party or by which it is bound.

 

(8)           
Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment
company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration
thereunder.

 

(9)           
The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that
all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with.

Section 13.5 Deposited Money, U.S. Government
Obligations and Foreign Government Obligations to be Held in Trust; Miscellaneous Provisions.

 

Subject to the provisions of the last
paragraph of Section 10.3, all money, U.S. Government Obligations and Foreign Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 13.6, the
Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 13.4 in
respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting
as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other
funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the U.S. Government Obligations or Foreign Government Obligations deposited pursuant to
Section 13.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by
law is for the account of the Holders of Outstanding Securities. Anything in this Article to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company Request any money, U.S. Government Obligations
or Foreign Government Obligations held by it as provided in Section 13.4 with respect to any Securities which, in the opinion
of a nationally recognized firm of independent public accountants, investment bankers or appraisers expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities.

 

Section 13.6 Reinstatement.

 

If the Trustee or the Paying Agent is unable
to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture
and such Securities from which the Company has been discharged or released pursuant to Section 13.2 or Section 13.3 shall be revived
and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the
Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 13.5 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest
on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of
the Holders of such Securities to receive such payment from the money so held in trust.

CONVERSION OF SECURITIES

 

Section 14.1 Applicability of Article.

 

The provisions of this Article shall be
applicable to the Securities of any series which are convertible into shares of Common Stock of the Company, and the issuance of
such shares of Common Stock upon the conversion of such Securities, except as otherwise specified as contemplated by Section 3.1
for the Securities of such series or in a supplemental indenture for the Securities of such series.

 

    63

     

    

 

 

Section 14.2 Exercise of Conversion
Privilege.

 

In order to exercise a conversion privilege,
the Holder of a Security of a series with such a privilege shall surrender such Security to the Conversion Agent at the office
or agency maintained for that purpose pursuant to Section 10.2, accompanied by a duly executed conversion notice to the Company
substantially in the form set forth in Section 2.6 stating that the Holder elects to convert such Security or a specified portion
thereof or convert such Securities in accordance with the procedure of the Depositary. Such notice shall also state, if different
from the name and address of such Holder, the name or names (with address) in which the certificate or certificates for shares
of Common Stock, which shall be issuable on such conversion, shall be issued. Securities surrendered for conversion shall (if so
required by the Company or the Trustee) be duly endorsed by or accompanied by instruments of transfer in forms satisfactory to
the Company and the Trustee duly executed by the Holder or its attorney duly authorized in writing. As promptly as practicable
after the receipt of such notice and of any payment required pursuant to a Board Resolution and, subject to Section 3.3, set forth,
or determined in the manner provided, in an Officers’ Certificate, or established in one or more indentures supplemental
hereto setting forth the terms of such series of Security, and the surrender of such Security in accordance with such reasonable
regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or agency at which such Security
is surrendered, to such Holder or on its written order, a certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of such Security (or specified portion thereof), in accordance with the provisions of such Board Resolution,
Officers’ Certificate or supplemental indenture, and cash as provided therein in respect of any fractional share of such
Common Stock otherwise issuable upon such conversion. Such conversion shall be deemed to have been effected immediately prior to
the close of business on the date on which such notice and such payment, if required, shall have been received in proper order
for conversion by the Company and such Security shall have been surrendered as aforesaid (unless such Holder shall have so surrendered
such Security and shall have instructed the Company to effect the conversion on a particular date following such surrender and
such Holder shall be entitled to convert such Security on such date, in which case such conversion shall be deemed to be effected
immediately prior to the close of business on such date) and at such time the rights of the Holder of such Security as such Security
Holder shall cease and the person or persons in whose name or names any certificate or certificates for shares of Common Stock
of the Company shall be issuable upon such conversion shall be deemed to have become the Holder or Holders of record of the shares
represented thereby. Except as set forth above and subject to the final paragraph of Section 3.7, no payment or adjustment shall
be made upon any conversion on account of any interest accrued on the Securities (or any part thereof) surrendered for conversion
or on account of any dividends on the Common Stock of the Company issued upon such conversion. In the case of any Security which
is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to or
on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of the same series, of authorized
denominations, in aggregate principal amount equal to the unconverted portion of such Security.

 

    64

     

    

 

Section 14.3 No Fractional
Shares.

 

No fractional share of Common Stock of the
Company shall be issued upon conversions of Securities of any series. If more than one Security shall be surrendered for conversion
at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis
of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered.
If, except for the provisions of this Section 14.3, any Holder of a Security or Securities would be entitled to a fractional share
of Common Stock of the Company upon the conversion of such Security or Securities, or specified portions thereof, the Company shall
pay to such Holder an amount in cash equal to the current market value of such fractional share computed, (i) if such Common Stock
is listed or admitted to unlisted trading privileges on a national securities exchange or market, on the basis of the last reported
sale price regular way on such exchange or market on the last trading day prior to the date of conversion upon which such a sale
shall have been effected, or (ii) if such Common Stock is not at the time so listed or admitted to unlisted trading privileges
on a national securities exchange or market, on the basis of the average of the bid and asked prices of such Common Stock in the
over-the-counter market, on the last trading day prior to the date of conversion, as reported by the National Quotation Bureau,
Incorporated or similar organization if the National Quotation Bureau, Incorporated is no longer reporting such information, or
if not so available, the fair market price as determined by the Board of Directors. For purposes of this Section, “trading
day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday other than any day on which the Common Stock is not
traded on the Nasdaq Global Market, or if the Common Stock is not traded on the Nasdaq Global Market, on the principal exchange
or market on which the Common Stock is traded or quoted.

 

Section 14.4 Adjustment of Conversion
Price or Conversion Rate.

 

The conversion price or conversion rate,
as the case may be, of Securities of any series that is convertible into Common Stock of the Company shall be adjusted for any
stock dividends, stock splits, reclassifications, combinations or similar transactions in accordance with the terms of the supplemental
indenture or Board Resolutions setting forth the terms of the Securities of such series. Whenever the conversion price or conversion
rate, as the case may be, is adjusted, the Company shall compute the adjusted conversion price or conversion rate, as the case
may be, in accordance with terms of the applicable Board Resolution or supplemental indenture and shall prepare and deliver to
the conversion agent and Trustee an Officers’ Certificate setting forth the adjusted conversion price or conversion rate,
as the case may be, and setting forth a brief statement in reasonable detail the facts upon which such adjustment is based, and
such certificate shall forthwith be filed at each office or agency maintained for the purpose of conversion of Securities pursuant
to Section 10.2 and, if different, with the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion
price or conversion rate, as the case may be, to be mailed, first class postage prepaid or electronically, to each Holder of Securities
of such series at its address appearing on the Security Register and to any conversion agent other than the Trustee.

Section 14.5 Notice of Certain Corporate
Actions.

 

In case:

 

(1)              
 the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out
of its retained earnings (other than a dividend for which approval of any shareholders of the Company is required) that would require
an adjustment pursuant to Section 14.4; or

 

(2)              
the Company shall authorize the granting to all or substantially all of the holders of its Common Stock of rights, options
or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights (other than any such grant
for which approval of any shareholders of the Company is required); or

 

(3)              
of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares
of Common Stock, or of any consolidation, merger or share exchange to which the Company is a party and for which approval of any
shareholders of the Company is required), or of the sale of all or substantially all of the assets of the Company; or

 

(4)              
of the voluntary or involuntary dissolution, liquidation or winding up of the Company;

 

then the Company shall cause to be filed with the conversion
agent and the Trustee, and shall cause to be mailed or electronically distributed to all Holders at their last addresses as they
shall appear in the Security Register, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to
the applicable record date hereinafter specified, a notice stating

 

(i)       the
date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record
is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights,
options or warrants are to be determined, or (ii) the date on which such reclassification, consolidation, merger, share exchange,
sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders
of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up.

 

Section 14.6 Reservation of Shares of
Common Stock.

 

The Company shall at all times reserve and
keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the
conversion of Securities, the full number of shares of Common Stock of the Company then issuable upon the conversion of all outstanding
Securities of any series that has conversion rights.

 

Section 14.7 Payment of Certain Taxes
upon Conversion.

 

Except as provided in the next
sentence, the Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of its
Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issue and delivery of shares of its Common Stock in a name other
than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and
until the person requesting such issue has paid to the Company the amount of any such tax, or has established, to the
satisfaction of the Company, that such tax has been paid.

 

    66

     

    

 

Section 14.8 Nonassessability.

 

The Company covenants that all shares of
its Common Stock that may be issued upon conversion of Securities will upon issue in accordance with the terms hereof be duly and
validly issued and fully paid and nonassessable.

 

Section 14.9 Provision in Case of Consolidation,
Merger or Sale of Assets.

 

In case of any consolidation or merger
of the Company with or into any other Person, any merger of another Person with or into the Company (other than a merger
which does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of
the Company) or any conveyance, sale, transfer or lease of all or substantially all of the assets of the Company, the Person
formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute
and deliver to the Trustee a supplemental indenture providing that the Holder of each Security of a series then Outstanding
that is convertible into Common Stock of the Company shall have the right thereafter (which right shall be the exclusive
conversion right thereafter available to said Holder), during the period such Security shall be convertible, to convert such
Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer or lease by a holder of the number of shares of Common Stock of the Company into which such
Security might have been converted immediately prior to such consolidation, merger, conveyance, sale, transfer or lease,
assuming such holder of Common Stock of the Company (i) is not a Person with which the Company consolidated or merged with or
into or which merged into or with the Company or to which such conveyance, sale, transfer or lease was made, as the case may
be (a “Constituent Person”), or an Affiliate of a Constituent Person and (ii) failed to exercise his rights of
election, if any, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash and other property receivable
upon such consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the
Company held immediately prior to such consolidation, merger, conveyance, sale, transfer or lease by others than a
Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised
(“Non-electing Share”), then for the purpose of this Section 14.9 the kind and amount of securities, cash and
other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by the holders of each
Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing
Shares). Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article
or in accordance with the terms of the supplemental indenture or Board Resolutions setting forth the terms of such
adjustments. The above provisions of this Section 14.9 shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers or leases. Notice of the execution of such a supplemental indenture shall be given by the
Company to the Holder of each Security of a series that is convertible into Common Stock of the Company as provided in
Section 1.6 promptly upon such execution. Neither the Trustee nor any conversion agent, if any, shall be under any
responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to
the kind or amount of shares of stock or other securities or property or cash receivable by Holders of Securities of a series
convertible into Common Stock of the Company upon the conversion of their Securities after any such consolidation, merger,
conveyance, transfer, sale or lease or to any such adjustment, but may accept as conclusive evidence of the correctness of
any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect thereto, which the Company
shall cause to be furnished to the Trustee upon request.

 

    67

     

    

 

Section 14.10 Duties of Trustee Regarding
Conversion.

 

Neither the Trustee nor any conversion agent
shall at any time be under any duty or responsibility to any Holder of Securities of any series that is convertible into Common
Stock of the Company to determine whether any facts exist which may require any adjustment of the conversion price or conversion
rate, as the case may be, or with respect to the nature or extent of any such adjustment when made, or with respect to the method
employed, whether herein or in any supplemental indenture, any resolutions of the Board of Directors or written instrument executed
by one or more officers of the Company provided to be employed in making the same. Neither the Trustee nor any conversion agent
shall be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock of the Company,
or of any securities or property, which may at any time be issued or delivered upon the conversion of any Securities and neither
the Trustee nor any conversion agent makes any representation with respect thereto. Subject to the provisions of Section 6.1, neither
the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares
of its Common Stock or stock certificates or other securities or property upon the surrender of any Security for the purpose of
conversion or to comply with any of the covenants of the Company contained in this Article 14 or in the applicable supplemental
indenture, resolutions of the Board of Directors or written instrument executed by one or more duly authorized officers of the
Company.

 

Section 14.11 Repayment of Certain Funds
upon Conversion.

 

Any funds which at any time shall have been
deposited by the Company or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of,
and premium, if any, and interest, if any, on any of the Securities (including, but not limited to, funds deposited for the sinking
fund referred to in Article 12 hereof and funds deposited pursuant to Article 13 hereof) and which shall not be required for such
purposes because of the conversion of such Securities as provided in this Article 14 shall after such conversion be repaid to the
Company by the Trustee upon the Company’s written request.

 

Section 14.12 Waiver of Jury Trial.

 

EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

 

    68

     

    

 

Section 14.13 Force Majeure.

 

In no event shall the Trustee be responsible
or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly,
forces beyond its control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances,
nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer
(software and hardware) services, or other unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication
facility; it being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the
banking industry to resume performance as soon as practicable under the circumstances.

 

Section 14.14 USA PATRIOT Act.

 

The parties hereto acknowledge that in accordance
with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of
terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity
that establishes a relationship or opens an account with the Trustee. The parties to this Indenture agree that they will provide
the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

 

Section 14.15 Calculations

 

Except
as otherwise provided in this Indenture or any supplemental indenture hereto, the Company shall be responsible for making all calculations
called for under this Indenture or any supplemental indenture hereto. The Company shall make any calculations in good faith and,
absent manifest error, the Company’s calculations shall be final and binding on all Holders. The Company shall provide a
schedule of its calculations to each of the Trustee and the conversion agent, and each of the Trustee and conversion agent may
rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee shall promptly
forward the Company’s calculations to any Holder upon the written request therefor.

clause (D) of the definition thereof, but without regard to the proviso to clause (B)(ii) of such definition);

subject to Section 4.03(I), the sending of a Redemption Notice will constitute a Make-Whole Fundamental Change only
with respect to the Notes called for Redemption pursuant to such Redemption Notice and not with respect to any other Notes.

 

“Make-Whole
Fundamental Change Conversion Period” has the following meaning:

 

(A)            in
the case of a Make-Whole Fundamental Change pursuant to clause (A) of the definition thereof, the period from, and
including, the Make-Whole Fundamental Change Effective Date of such Make-Whole Fundamental Change to, and including, the thirty-fifth
(35th) Trading Day after such Make-Whole Fundamental Change Effective Date (or, if such Make-Whole Fundamental Change also constitutes

the case of a Make-Whole Fundamental Change pursuant to clause (B) of the definition thereof, the period from, and
including, the Redemption Notice Date for the related Redemption to, and including, the Business Day immediately before the related
Redemption Date;

 

provided, however, that if

called) for Redemption occurs during the Make-Whole Fundamental Change Conversion Period for both a Make-Whole Fundamental Change
occurring pursuant to clause (A) of the definition of “Make-Whole Fundamental Change” and a Make-Whole
Fundamental Change resulting from such Redemption pursuant to clause (B) of such definition, then, notwithstanding
anything to the contrary in Section 5.07, solely for purposes of such conversion, (x) such Conversion Date will
be deemed to occur solely during the Make-Whole Fundamental Change Conversion Period for the Make-Whole Fundamental Change with
the earlier Make-Whole Fundamental Change Effective Date; and (y) the Make-Whole Fundamental Change with the later Make-Whole
Fundamental Change Effective Date will be deemed not to have occurred.

by such an agent will be deemed, for purposes of the Indenture, to be authenticated by the Trustee. Each duly appointed authenticating

(A)            Accrual
of Interest. Each Note will accrue interest at a rate per annum equal to 5.25% (the “Stated Interest”),
plus any Special Interest that may accrue pursuant to Section 7.03. Stated Interest on each Note will (i) accrue
from, and including, the most recent date to which Stated Interest has been paid or duly provided for (or, if no Stated Interest
has theretofore been paid or duly provided for, the date set forth in the certificate representing such Note as the date from,
and including, which Stated Interest will begin to accrue in such circumstance) to, but excluding, the date of payment of such
Stated Interest; and (ii) be, subject to Sections 4.02(D), 4.03(E) and 5.02(D) (but without
duplication of any payment of interest), payable semi-annually in arrears on each Interest Payment Date, beginning on the first
Interest Payment Date set forth in the certificate representing such Note, to the Holder of such Note as of the Close of Business
on the immediately preceding Regular Record Date (whether or not a Business Day). Stated Interest, and, if applicable, Special
Interest, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

 

    	 	- 16 -	 

     

    

 

(B)            Defaulted
Amounts. If the Company fails to pay any amount (a “Defaulted Amount”) payable on a Note on or before the
due date therefor as provided in the Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such
Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise entitled to such payment; (ii) to
the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal
to the rate per annum at which Stated Interest accrues, from, and including, such due date to, but excluding, the date of payment
of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment
date selected by the Company to the Holder of such Note as of the Close of Business on a special record date selected by the Company,
provided that such special record date must be no more than fifteen (15), nor less than ten (10), calendar days before such
payment date; and (iv) at least fifteen (15) calendar days before such special record date, the Company will send notice to
the Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and
Default Interest to be paid on such payment date.

 

(C)            Delay
of Payment when Payment Date is Not a Business Day. If the due date for a payment on a Note as provided in the Indenture is
not a Business Day, then, notwithstanding anything to the contrary in the Indenture or the Notes, such payment may be made on the
immediately following Business Day and no interest will accrue on such payment as a result of the related delay. Solely for purposes
of the immediately preceding sentence, a day on which the corporate trust office of the Trustee (or, if the Trustee is not acting
as the Paying Agent, the applicable place of payment) is authorized or required by law or executive order to close or be closed
will be deemed not to be a “Business Day.”

 

Section 2.06.       Registrar,
Paying Agent and Conversion Agent.

 

(A)            Generally.
The Company will maintain (i) an office or agency in the continental United States where Notes may be presented for registration
of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States
where Notes may be presented for payment (the “Paying Agent”); and (iii) an office or agency in the continental
United States where Notes may be presented for conversion (the “Conversion Agent”). If the Company fails to
maintain a Registrar, Paying Agent or Conversion Agent, then the Trustee will act as such. For the avoidance of doubt, the Company
or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent.

 

(B)            Duties
of the Registrar. The Registrar will keep a record (the “Register”) of the names and addresses of the Holders,
the Notes held by each Holder and the transfer, exchange, repurchase, Redemption and conversion of Notes. Absent manifest error,
the entries in the Register will be conclusive and the Company and the Trustee may treat each Person whose name is recorded as
a Holder in the Register as a Holder for all purposes. The Register will be in written form or in any form capable of being converted
into written form reasonably promptly.

 

    	 	- 17 -	 

     

    

 

(C)            Co-Agents;
Company’s Right to Appoint Successor Registrars, Paying Agents and Conversion Agents. The Company may appoint one or
more co-Registrars, co-Paying Agents or co-Conversion Agents, each of whom will be deemed to be a Registrar, Paying Agent or Conversion
Agent, as applicable, under the Indenture. Subject to Section 2.06(A), the Company may change any Registrar, Paying
Agent or Conversion Agent (including appointing itself or any of its Subsidiaries to act in such capacity) without notice to any
Holder. The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any,
not a party to the Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will
implement the provisions of the Indenture that relate to such Note Agent.

 

(D)            Initial
Appointments. The Company appoints the Trustee as the initial Paying Agent, the initial Registrar and the initial Conversion
Agent and the Trustee’s office in the United States as the place where Notes may be presented for payment.

 

Section 2.07.       Paying
Agent and Conversion Agent to Hold Property in Trust.

 

The Company will require
each Paying Agent or Conversion Agent that is not the Trustee to agree in writing that such Note Agent will (A) hold in trust
for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery due on the
Notes; and (B) notify the Trustee of any default by the Company in making any such payment or delivery. The Company, at any
time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as
applicable, all money and other property held by it to the Trustee, after which payment or delivery, as applicable, such Note Agent
(if not the Company or any of its Subsidiaries) will have no further liability for such money or property. If the Company or any
of its Subsidiaries acts as Paying Agent or Conversion Agent, then (A) it will segregate and hold in a separate trust fund
for the benefit of the Holders or the Trustee all money and other property held by it as Paying Agent or Conversion Agent; and
(B) references in the Indenture or the Notes to the Paying Agent or Conversion Agent holding cash or other property, or to
the delivery of cash or other property to the Paying Agent or Conversion Agent, in each case for payment or delivery to any Holders
or the Trustee or with respect to the Notes, will be deemed to refer to cash or other property so segregated and held separately,
or to the segregation and separate holding of such cash or other property, respectively. Upon the occurrence of any event pursuant
to in clause (ix) or (x) of Section 7.01(A) with respect to the Company (or with respect
to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or Conversion
Agent, as applicable, for the Notes.

 

Section 2.08.       Holder
Lists.

 

If the Trustee is not
the Registrar, the Company will furnish to the Trustee, no later than seven (7) Business Days before each Interest Payment
Date, and at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may reasonably
require, of the names and addresses of the Holders; provided, that no such list needs to be furnished by the Company to
the Trustee for so long as the Trustee is acting as the Security Registrar.

 

Section 2.09.       Legends.

 

(A)            Global
Note Legend. Each Global Note will bear the Global Note Legend (or any similar legend, not inconsistent with the Indenture,
required by the Depositary for such Global Note).

 

    	 	- 18 -	 

     

    

 

(B)            Other
Legends. A Note may bear any other legend or text, not inconsistent with the Indenture, as may be required by applicable law
or by any securities exchange or automated quotation system on which such Note is traded or quoted.

 

(C)            Acknowledgement
and Agreement by the Holders. A Holder’s acceptance of any Note bearing any legend required by this Section 2.09
will constitute such Holder’s acknowledgement of, and agreement to comply with, the restrictions set forth in such legend.

 

Section 2.10.       Transfers
and Exchanges; Certain Transfer Restrictions.

 

(A)            Provisions
Applicable to All Transfers and Exchanges.

 

(i)            Subject
to this Section 2.10, Physical Notes and beneficial interests in Global Notes may be transferred or exchanged from
time to time and the Registrar will record each such transfer or exchange in the Register.

 

(ii)           Each
Note issued upon transfer or exchange of any other Note (such other Note being referred to as the “old Note” for purposes
of this Section 2.10(A)(ii)) or portion thereof in accordance with the Indenture will be the valid obligation of the
Company, evidencing the same indebtedness, and entitled to the same benefits under the Indenture, as such old Note or portion thereof,
as applicable.

 

(iii)          The
Company, the Trustee and the Note Agents will not impose any service charge on any Holder for any transfer, exchange or conversion
of Notes, but the Company, the Trustee, the Registrar and the Conversion Agent 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
Notes, other than exchanges pursuant to Sections 2.11, 2.16 or 8.05 not involving any transfer.

 

(iv)          Notwithstanding
anything to the contrary in the Indenture or the Notes, a Note may not be transferred or exchanged in part unless the portion to
be so transferred or exchanged is in an Authorized Denomination.

 

(v)           The
Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any transfer restrictions imposed
under the Indenture or applicable law with respect to any Note Security, other than to require the delivery of such certificates
or other documentation or evidence as expressly required by the Indenture and to examine the same to determine substantial compliance
as to form with the requirements of the Indenture.

 

(vi)          Each
Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any, required by Section 2.09.

 

(vii)         Upon
satisfaction of the requirements of the Indenture to effect a transfer or exchange of any Note, the Company will cause such transfer
or exchange to be effected as soon as reasonably practicable but in no event later than the second (2nd) Business Day after the
date of such satisfaction.

 

    	 	- 19 -	 

     

    

 

(B)         Transfers
and Exchanges of Global Notes.

 

(i)           Subject
to the immediately following sentence, no Global Note may be transferred or exchanged in whole except (x) by the Depositary
to a nominee of the Depositary; (y) by a nominee of the Depositary to the Depositary or to another nominee of the Depositary;
or (z) by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. No Global
Note (or any portion thereof) may be transferred to, or exchanged for, a Physical Note; provided, however, that a
Global Note will be exchanged, pursuant to customary procedures, for one or more Physical Notes if:

 

(1)            (x) the
Depositary notifies the Company or the Trustee that the Depositary is unwilling or unable to continue as depositary for such Global
Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange
Act and, in each case, the Company fails to appoint a successor Depositary within ninety (90) days of such notice or cessation;

 

(2)            an
Event of Default has occurred and is continuing and the Company, the Trustee or the Registrar has received a written request from
the Depositary, or from a holder of a beneficial interest in such Global Note, to exchange such Global Note or beneficial interest,
as applicable, for one or more Physical Notes; or

 

(3)            the
Company, in its sole discretion, permits the exchange of any beneficial interest in such Global Note for one or more Physical Notes
at the request of the owner of such beneficial interest.

 

(ii)          Upon
satisfaction of the requirements of the Indenture to effect a transfer or exchange of any Global Note (or any portion thereof):

 

(1)            the
Trustee will reflect any resulting decrease of the principal amount of such Global Note by notation on the “Schedule of Exchanges
of Interests in the Global Note” forming part of such Global Note (and, if such notation results in such Global Note having
a principal amount of zero, the Company may (but is not required to) instruct the Trustee to cancel such Global Note pursuant to
Section 2.14);

 

(2)            if
required to effect such transfer or exchange, then the Trustee will reflect any resulting increase of the principal amount of any
other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other
Global Note or in accordance with its customary procedures;

 

(3)            if
required to effect such transfer or exchange, then the Company will issue, execute and deliver, and the Trustee will authenticate,
in each case in accordance with Section 2.02, a new Global Note bearing each legend, if any, required by Section 2.09;
and

 

    	 	- 20 -	 

     

    

 

(4)            if
such Global Note (or such portion thereof), or any beneficial interest therein, is to be exchanged for one or more Physical Notes,
then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02,
one or more Physical Notes that are in Authorized Denominations (not to exceed, in the aggregate, the principal amount of such
Global Note to be so exchanged), are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant
to customary procedures) and bear each legend, if any, required by Section 2.09.

 

(iii)          Each
transfer or exchange of a beneficial interest in any Global Note will be made in accordance with the Depositary Procedures.

 

(C)          Transfers
and Exchanges of Physical Notes.

 

(i)            Subject
to this Section 2.10, a Holder of a Physical Note may (x) transfer such Physical Note (or any portion thereof
in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in
an Authorized Denomination) for one or more other Physical Notes in Authorized Denominations having an aggregate principal amount
equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted
by the Depositary Procedures, transfer such Physical Note (or any portion thereof in an Authorized Denomination) in exchange for
a beneficial interest in one or more Global Notes; provided, however, that, to effect any such transfer or exchange,
such Holder must surrender such Physical Note to be transferred or exchanged to the office of the Registrar, together with any
appropriate endorsements or transfer instruments reasonably required by the Company, the Trustee or the Registrar.

 

(ii)          Upon
the satisfaction of the requirements of the Indenture to effect a transfer or exchange of any Physical Note (such Physical Note
being referred to as the “old Physical Note” for purposes of this Section 2.10(C)(ii)) of a Holder (or
any portion of such old Physical Note in an Authorized Denomination):

 

(1)            such
old Physical Note will be promptly cancelled pursuant to Section 2.14;

 

(2)            if
such old Physical Note is to be transferred or exchanged only in part, then the Company will issue, execute and deliver, and the
Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are
in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such old Physical Note not
to be transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required
by Section 2.09;

 

    	 	- 21 -	 

     

    

 

(3)          in
the case of a transfer:

 

(a)            to
the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred
in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global
Notes by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note(s) or
in accordance with its customary procedures, which increase(s) are in Authorized Denominations and aggregate to the principal
amount to be so transferred, and which Global Note(s) bear each legend, if any, required by Section 2.09; provided,
however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no
Global Notes bearing each legend, if any, required by Section 2.09 then exist, because any such increase will result
in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary
or otherwise), then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance
with Section 2.02, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate principal
amount equal to the principal amount to be so transferred; and (y) bear each legend, if any, required by Section 2.09;
and

 

(b)            to
a transferee that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred in the form of
one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance
with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal
amount equal to the principal amount to be so transferred; (y) are registered in the name of such transferee; and (z) bear
each legend, if any, required by Section 2.09; and

 

(4)            in
the case of an exchange, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance
with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal
amount equal to the principal amount to be so exchanged; (y) are registered in the name of the Person to whom such old Physical
Note was registered; and (z) bear each legend, if any, required by Section 2.09.

 

(D)         Transfers
of Notes Subject to Redemption, Repurchase or Conversion. Notwithstanding anything to the contrary in the Indenture or the
Notes, the Company, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has
been surrendered for conversion, except to the extent that any portion of such Note is not subject to conversion; (ii) is
subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to Section 4.02(F),
except to the extent that any portion of such Note is not subject to such notice or the Company fails to pay the applicable Fundamental
Change Repurchase Price when due; or (iii) has been selected for Redemption pursuant to a Redemption Notice, except to the
extent that the Company fails to pay the applicable Redemption Price when due.

Section 2.11.      Exchange
and Cancellation of Notes to Be Converted, Redeemed or Repurchased.

 

(A)         Partial
Conversions and Repurchases of Physical Notes. If only a portion of a Physical Note of a Holder is to be converted pursuant
to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, as soon as reasonably practicable
after such Physical Note is surrendered for such conversion or repurchase, the Company will cause such Physical Note to be exchanged,
pursuant and subject to Section 2.10(C), for (i) one or more Physical Notes that are in Authorized Denominations
and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased,
as applicable, and deliver such Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal
to the principal amount to be so converted or repurchased, as applicable, which Physical Note will be converted or repurchased,
as applicable, pursuant to the terms of the Indenture; provided, however, that the Physical Note referred to in this
clause (ii) need not be issued at any time after which such principal amount subject to such conversion or repurchase, as
applicable, is deemed to cease to be outstanding pursuant to Section 2.17.

 

(B)         Cancellation
of Converted, Redeemed and Repurchased Notes.

 

(i)            Physical
Notes. If a Physical Note (or any portion thereof that has not theretofore been exchanged pursuant to Section 2.11(A))
of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change
or Redemption, then, promptly after the later of the time such Physical Note (or such portion) is deemed to cease to be outstanding
pursuant to Section 2.17 and the time such Physical Note is surrendered for such conversion or repurchase, as applicable,
(1) such Physical Note will be cancelled pursuant to Section 2.14; and (2) in the case of a partial conversion
or repurchase, the Company will issue, execute and deliver to such Holder, and the Trustee will authenticate, in each case in accordance
with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal
amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased; (y) are registered
in the name of such Holder; and (z) bear each legend, if any, required by Section 2.09.

 

(ii)           Global
Notes. If a Global Note (or any portion thereof) is to be converted pursuant to Article 5 or repurchased pursuant
to a Repurchase Upon Fundamental Change or Redemption, then, promptly after the time such Note (or such portion) is deemed to cease
to be outstanding pursuant to Section 2.17, the Trustee will reflect a decrease of the principal amount of such Global
Note in an amount equal to the principal amount of such Global Note to be so converted, redeemed or repurchased, as applicable,
by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if
the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to Section 2.14).

 

    	 	- 23 -	 

     

    

 

Section 2.12.     Replacement
Notes.

 

If a Holder of any
Note claims that such Note has been mutilated, lost, destroyed or wrongfully taken, then the Company will issue, execute and deliver,
and the Trustee will authenticate, in each case in accordance with Section 2.02, a replacement Note upon surrender
to the Trustee of such mutilated Note, or upon delivery to the Trustee of evidence of such loss, destruction or wrongful taking
reasonably satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Note, the Company
and the Trustee will require the Holder thereof to provide such security or indemnity that is reasonably satisfactory to the Company
and the Trustee to protect the Company and the Trustee from any loss that any of them may suffer if such Note is replaced.

 

Every replacement Note
issued pursuant to this Section 2.12 will be an additional obligation of the Company and will be entitled to all of
the benefits of the Indenture equally and ratably with all other Notes issued under the Indenture.

 

Section 2.13.     Registered
Holders; Certain Rights with Respect to Global Notes.

 

Only the Holder of
a Note will have rights under the Indenture as the owner of such Note. Without limiting the generality of the foregoing, Depositary
Participants will have no rights as such under the Indenture with respect to any Global Note held on their behalf by the Depositary
or its nominee, or by the Trustee as its custodian, and the Company, the Trustee and the Note Agents, and their respective agents,
may treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever; provided, however,
that (A) the Holder of any Global Note may grant proxies and otherwise authorize any Person, including Depositary Participants
and Persons that hold interests in Notes through Depositary Participants, to take any action that such Holder is entitled to take
with respect to such Global Note under the Indenture or the Notes; and (B) the Company and the Trustee, and their respective
agents, may give effect to any written certification, proxy or other authorization furnished by the Depositary.

 

Section 2.14.     Cancellation.

 

Without limiting the
generality of Section 3.06, the Company may at any time deliver Notes to the Trustee for cancellation. The Registrar,
the Paying Agent and the Conversion Agent will forward to the Trustee each Note duly surrendered to them for transfer, exchange,
payment or conversion. The Trustee will promptly cancel all Notes so surrendered to it in accordance with its customary procedures.
Without limiting the generality of Section 2.03(B), the Company may not originally issue new Notes to replace Notes
that it has paid or that have been cancelled upon transfer, exchange, payment or conversion.

 

Section 2.15.     Notes
Held by the Company or its Affiliates.

 

Without limiting the
generality of Section 3.06, in determining whether the Holders of the required aggregate principal amount of Notes
have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates will be deemed not to be
outstanding; provided, however, that, for purposes of determining whether the Trustee is protected in relying on
any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded.

 

    	 	- 24 -	 

     

    

 

Section 2.16.     Temporary
Notes.

 

Until definitive Notes
are ready for delivery, the Company may issue, execute and deliver, and the Trustee will authenticate, in each case in accordance
with Section 2.02, temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have
variations that the Company considers appropriate for temporary Notes. The Company will promptly prepare, issue, execute and deliver,
and the Trustee will authenticate, in each case in accordance with Section 2.02, definitive Notes in exchange for temporary
Notes. Until so exchanged, each temporary Note will in all respects be entitled to the same benefits under the Indenture as definitive
Notes.

 

Section 2.17.     Outstanding
Notes.

 

(A)        Generally.
The Notes that are outstanding at any time will be deemed to be those Notes that, at such time, have been duly executed and authenticated,
excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to the Trustee
for cancellation in accordance with Section 2.14; (ii) assigned a principal amount of zero by notation on the
“Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such Note; (iii) paid
in full in accordance with the Indenture; or (iv) deemed to cease to be outstanding to the extent provided in, and subject
to, clause (B), (C) or (D) of this Section 2.17.

 

(B)         Replaced
Notes. If a Note is replaced pursuant to Section 2.12, then such Note will cease to be outstanding at the time
of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held by
a “bona fide purchaser” under applicable law.

 

(C)         Maturing
Notes and Notes Called for Redemption or Subject to Repurchase. If, by 10:00 a.m. New York City time on a Redemption Date,
a Fundamental Change Repurchase Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Redemption
Price, Fundamental Change Repurchase Price or principal amount, respectively, together, in each case, with the aggregate interest,
in each case due on such date, then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions
thereof) to be redeemed or repurchased, or that mature, on such date will be deemed, as of such date, to cease to be outstanding,
except to the extent provided in Sections 4.02(D), 4.03(E) or 5.02(D); and (ii) the rights of the
Holders of such Notes (or such portions thereof), as such, will terminate with respect to such Notes (or such portions thereof),
other than the right to receive the Redemption Price, Fundamental Change Repurchase Price or principal amount, as applicable, of,
and accrued and unpaid interest on, such Notes (or such portions thereof), in each case as provided in the Indenture.

 

(D)         Notes
to Be Converted. At the Close of Business on the Conversion Date for any Note (or any portion thereof) to be converted, such
Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant
to Section 5.03(D) or Section 5.02(D), upon such conversion) be deemed to cease to be outstanding,
except to the extent provided in Section 5.02(D).

 

    	 	- 25 -	 

     

    

 

(E)        Cessation
of Accrual of Interest. Except as provided in Sections 4.02(D), 4.03(E) or 5.02(D), interest will
cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this Section 2.17,
to cease to be outstanding, unless there occurs a default in the payment or delivery of any cash or other property due on such
Note.

 

Section 2.18.     Repurchases
by the Company.

 

Without limiting the
generality of Section 2.14, the Company may, from time to time, repurchase Notes in open market purchases or in negotiated
transactions without delivering prior notice to Holders.

 

Section 2.19.     CUSIP
and ISIN Numbers.

 

The Company may use
one or more CUSIP or ISIN numbers to identify any of the Notes, and, if so, the Company and the Trustee will use such CUSIP or
ISIN number(s) in notices to Holders; provided, however, that (i) the Trustee makes no representation as
to the correctness or accuracy of any such CUSIP or ISIN number; and (ii) the effectiveness of any such notice will not be
affected by any defect in, or omission of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change
in the CUSIP or ISIN number(s) identifying any Notes. Neither the Trustee nor any Note Agent will have any responsibility
or liability for any actions taken or not taken by the Depositary.

 

Article 3.     Covenants

 

Section 3.01.     Payment
on Notes.

 

(A)        Generally.

15(d) of the Exchange Act within fifteen (15) calendar days after the date that the Company is required to so file the same
(after giving effect to all applicable grace periods under the Exchange Act); provided, however, that the Company
need not send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied,

(B)          Trustee’s
Disclaimer. The Trustee need not determine whether the Company has filed any material via the EDGAR system (or such successor).
Delivery of such material and the sending or filing of reports pursuant to Section 3.02(A) will not be deemed
to constitute constructive notice to the Trustee of any information contained, or determinable from information contained, therein,
including the Company’s compliance with any of its covenants under the Indenture (as to which the Trustee is entitled to
rely exclusively on Officer’s Certificates). The Trustee will not be obligated to monitor or confirm, on a continuing basis
or otherwise, the Company’s compliance with such covenants or obligations under the Exchange Act to file reports.

 

Section 3.03.     Compliance
and Default Certificates.

 

(A)        Annual
Compliance Certificate. Within ninety (90) days after December 31, 2020 and each fiscal year of the Company ending thereafter,

during such fiscal year with a view towards determining whether any Default or Event of Default has occurred; and (ii) whether,

Extension and Usury Laws.

 

To the extent that
it may lawfully do so, the Company (A) agrees that it will not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law (wherever or whenever enacted or in force) that may
affect the covenants or the performance of the Indenture; and (B) expressly waives all benefits or advantages of any such
law and agrees that it will not, by resort to any such law, hinder, delay or impede the execution of any power granted to the Trustee
by the Indenture, but will suffer and permit the execution of every such power as though no such law has been enacted.

 

Section 3.05.     Corporate
Existence.

 

Subject to Article 6,
the Company will cause to preserve and keep in full force and effect:

 

(A)         its
corporate existence in accordance with the organizational documents of the Company; and

 

(B)         the
material rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries;

 

    	 	- 27 -	 

     

    

 

provided, however, that the
Company need not preserve or keep in full force and effect any such license or franchise if the Board of Directors determines that
(x) the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken
as a whole; and (y) the loss thereof is not, individually or in the aggregate, materially adverse to the Holders.

 

Section 3.06.     Restriction
on Acquisition of Notes by the Company and its Affiliates.

 

The Company will promptly
deliver to the Trustee for cancellation in accordance with its customary provisions all Notes that the Company or any of its Subsidiaries

Article 4.     Repurchase
and Redemption

 

Section 4.01.     No
Sinking Fund.

 

No sinking fund is
required to be provided for the Notes.

 

Section 4.02.     Right
of Holders to Require the Company to Repurchase Notes upon a Fundamental Change.

 

(A)         Right
of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change. Subject to the other terms of this Section 4.02,
if a Fundamental Change occurs, then each Holder will have the right (the “Fundamental Change Repurchase Right”)
to require the Company to repurchase such Holder’s Notes (or any portion thereof in an Authorized Denomination) on the Fundamental
Change Repurchase Date for such Fundamental Change for a cash purchase price equal to the Fundamental Change Repurchase Price.

 

(B)         Repurchase
Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not
been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (except in the case
of an acceleration resulting solely from the failure to pay the related Fundamental Change Repurchase Price, on such Fundamental
Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant to this Section 4.02; and
(ii) the Company will cause any Notes theretofore surrendered for such Repurchase upon Fundamental Change to be returned to
the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company,
the Trustee or the Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary Procedures).

 

    	 	- 28 -	 

     

    

 

(C)         Fundamental
Change Repurchase Date. The Fundamental Change Repurchase Date for any Fundamental Change will be a Business Day of the Company’s
choosing that is no more than thirty-five (35), nor less than twenty (20), Business Days after the date the Company sends the related
Fundamental Change Notice pursuant to Section 4.02(E).

 

(D)         Fundamental
Change Repurchase Price. The Fundamental Change Repurchase Price for any Note to be repurchased upon a Repurchase Upon Fundamental
Change following a Fundamental Change is an amount in cash equal to the principal amount of such Note plus accrued and unpaid interest
on such Note to, but excluding, the Fundamental Change Repurchase Date for such Fundamental Change; provided, however,
that if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date,
then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such
Repurchase Upon Fundamental Change, to receive, on or, at the Company’s election, before such Interest Payment Date, the
unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these
purposes, that such Note remained outstanding through such Interest Payment Date, if such Fundamental Change Repurchase Date is
before such Interest Payment Date); and (ii) the Fundamental Change Repurchase Price will not include accrued and unpaid interest
on such Note to, but excluding, such Fundamental Change Repurchase Date. For the avoidance of doubt, if an Interest Payment Date
is not a Business Day within the meaning of Section 2.05(C) and such Fundamental Change Repurchase Date occurs
on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding,
such Interest Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day to Holders at
of the Close of Business on the immediately preceding Regular Record Date; and (y) the Fundamental Change Repurchase Price
will include interest on Notes to be repurchased from, and including, such Interest Payment Date, all subject to the Depositary
Procedures (in the case of a Global Note).

 

(E)          Fundamental
Change Notice. On or before the twentieth (20th) calendar day after the effective date of a Fundamental Change, the Company
will (x) send to each Holder, the Trustee and the Paying Agent a notice of such Fundamental Change (a “Fundamental
Change Notice”) and (y) substantially contemporaneously therewith, issue a press release through such national newswire
service as the Company then uses (or publish the same through such other widely disseminated public medium as the Company then
uses, including its website) containing the information set forth in the Fundamental Change Notice.

 

Such Fundamental Change
Notice must state:

 

(i)            briefly,
the events causing such Fundamental Change;

 

(ii)           the
effective date of such Fundamental Change;

 

(iii)          the
procedures that a Holder must follow to require the Company to repurchase its Notes pursuant to this Section 4.02,
including the deadline for exercising the Fundamental Change Repurchase Right and the procedures for submitting and withdrawing
a Fundamental Change Repurchase Notice;

 

(iv)          the
Fundamental Change Repurchase Date for such Fundamental Change;

 

    	 	- 29 -	 

     

    

 

(v)           the
Fundamental Change Repurchase Price per $1,000 principal amount of Notes for such Fundamental Change (and, if such Fundamental
Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing
of the interest payment payable pursuant to the proviso to Section 4.02(D));

 

(vi)          the
name and (if Physical Notes are outstanding) the address of the Paying Agent and the Conversion Agent;

 

(vii)         the
Conversion Rate in effect on the date of such Fundamental Change Notice and a description and quantification of any adjustments
to the Conversion Rate that may result from such Fundamental Change (including pursuant to Section 5.07);

 

(viii)        that
Notes for which a Fundamental Change Repurchase Notice has been duly tendered and not duly withdrawn must be delivered to the Paying
Agent (or, in the case of a Global Note, in accordance with the Depositary Procedures) for the Holder thereof to be entitled to
receive the Fundamental Change Repurchase Price;

 

(ix)           that
Notes (or any portion thereof) that are subject to a Fundamental Change Repurchase Notice that has been duly tendered may be converted
only if such Fundamental Change Repurchase Notice is withdrawn in accordance with the Indenture; and

 

(x)             the
CUSIP and ISIN numbers, if any, of the Notes.

 

Neither the failure
to deliver a Fundamental Change Notice nor any defect in a Fundamental Change Notice will limit the Fundamental Change Repurchase
Right of any Holder or otherwise affect the validity of any proceedings relating to any Repurchase Upon Fundamental Change.

 

(F)          Procedures
to Exercise the Fundamental Change Repurchase Right.

 

(i)          Delivery
of Fundamental Change Repurchase Notice and Notes to Be Repurchased. To exercise its Fundamental Change Repurchase Right for
a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent:

 

(1)            before
the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or such later time
as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and

 

(2)            such
Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer via the Depositary Procedures (if
such note is a Global Note).

 

The Paying Agent will promptly
deliver to the Company a copy of each Fundamental Change Repurchase Notice that it receives.

 

    	 	- 30 -	 

     

    

 

(ii)          Contents
of Fundamental Change Repurchase Notices. Each Fundamental Change Repurchase Notice with respect to a Note must state:

 

(1)            if
such Note is a Physical Note, the certificate number of such Note;

 

(2)            the
principal amount of such Note to be repurchased, which must be an Authorized Denomination; and

 

(3)            that
such Holder is exercising its Fundamental Change Repurchase Right with respect to such principal amount of such Note;

 

provided, however,
that if such Note is a Global Note, then such Fundamental Change Repurchase Notice must comply with the Depositary Procedures (and
any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy
the requirements of this Section 4.02(F)).

 

(iii)       Withdrawal
of Fundamental Change Repurchase Notice. A Holder that has delivered a Fundamental Change Repurchase Notice with respect to
a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent
at any time before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date.
Such withdrawal notice must state:

 

(1)            if
such Note is a Physical Note, the certificate number of such Note;

 

(2)            the
principal amount of such Note to be withdrawn, which must be an Authorized Denomination; and

 

(3)            the
principal amount of such Note, if any, that remains subject to such Fundamental Change Repurchase Notice, which must be an Authorized
Denomination;

 

provided, however,
that if such Note is a Global Note, then such withdrawal notice must comply with the Depositary Procedures (and any such withdrawal
notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)).

 

Upon receipt of any such withdrawal
notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly deliver a copy of such withdrawal
notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof in
accordance with Section 2.11, treating such Note as having been then surrendered for partial repurchase in the amount
set forth in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof.

 

(G)        Payment
of the Fundamental Change Repurchase Price. Without limiting the Company’s obligation to deposit the Fundamental Change
Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the Fundamental Change Repurchase
Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon Fundamental Change to be paid to the Holder
thereof on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such
Note is delivered to the Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the repurchase,
and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be repurchased are complied with
(in the case of a Global Note). For the avoidance of doubt, interest payable pursuant to the proviso to Section 4.02(D) on
any Note to be repurchased pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso, subject to the
Depositary Procedures (in the case of a Global Note).

 

    	 	- 31 -	 

     

    

 

(H)        Third
Party May Conduct Repurchase Offer In Lieu of the Company. Notwithstanding anything to the contrary in this Section 4.02,
the Company will be deemed to satisfy its obligations under this Section 4.02 if (i) one or more third parties
conduct any Repurchase Upon Fundamental Change and related offer to repurchase Notes otherwise required by this Section 4.02
in a manner that would have satisfied the requirements of this Section 4.02 if conducted directly by the Company; and
(ii) an owner of a beneficial interest in any Note repurchased by such third party or parties will not receive a lesser amount
(as a result of taxes, additional expenses or for any other reason) than such owner would have received had the Company repurchased
such Note.

 

(I)         Compliance
with Applicable Securities Laws. To the extent applicable, the Company will comply with all federal and state securities laws
in connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and 14e-1 under the Exchange
Act and filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change
in the manner set forth in the Indenture.

 

(J)         Repurchase
in Part. Subject to the terms of this Section 4.02, Notes may be repurchased pursuant to a Repurchase Upon Fundamental
Change in part, but only in Authorized Denominations. Provisions of this Section 4.02 applying to the repurchase of
a Note in whole will equally apply to the repurchase of a permitted portion of a Note.

 

Section 4.03.     Right
of the Company to Redeem the Notes.

 

(A)        No
Right to Redeem Before August 15, 2023. The Company may not redeem the Notes at its option at any time before August 15,
2023.

 

(B)        Right
to Redeem the Notes on or After August 15, 2023. Subject to the terms of this Section 4.03, the Company has
the right, at its election, to redeem all, or any portion in an Authorized Denomination, of the Notes, at any time, and from time
to time, on a Redemption Date on or after August 15, 2023 and on or before the fiftieth (50th) Scheduled Trading Day immediately
before the Maturity Date, for a cash purchase price equal to the Redemption Price, but only if the Last Reported Sale Price per
share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price on (i) each of at least twenty
(20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the Trading
Day immediately before the Redemption Notice Date for such Redemption; and (ii) the Trading Day immediately before such Redemption
Notice Date. For the avoidance of doubt, the calling of any Notes for Redemption will constitute a Make-Whole Fundamental Change
with respect to such Notes pursuant to clause (B) of the definition thereof.

 

    	 	- 32 -	 

     

    

 

(C)          Redemption
Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not
been rescinded on or before the Redemption Date (except in the case of an acceleration resulting solely from the failure to pay
the related Redemption Price, on such Redemption Date), then (i) the Company may not call for Redemption or otherwise redeem
any Notes pursuant to this Section 4.03; and (ii) the Company will cause any Notes theretofore surrendered for
such Redemption to be returned to the Holders thereof.

 

(D)         Redemption
Date. The Redemption Date for any Redemption will be a Business Day of the Company’s choosing that is no more than seventy-five
(75), nor less than fifty-five (55), Scheduled Trading Days after the Redemption Notice Date for such Redemption; provided,
however, that if, in accordance with Section 5.03(A)(iii), the Company has elected to settle all conversions
of Notes with a Conversion Date that occurs on or after such Redemption Notice Date and on or before the Business Day immediately
before the Redemption Date by Physical Settlement, then the Company may instead elect to choose a Redemption Date that is a Business
Day no more than forty-five (45), nor less than fifteen (15), calendar days after such Redemption Notice Date.

 

(E)         Redemption
Price. The Redemption Price for any Note called for Redemption is an amount in cash equal to the principal amount of such Note
plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption; provided, however,
that if such Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, then (i) the
Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Redemption, to
receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued
on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding
through such Interest Payment Date, if such Redemption Date is before such Interest Payment Date); and (ii) the Redemption
Price will not include accrued and unpaid interest on such Note to, but excluding, such Redemption Date. For the avoidance of doubt,
if an Interest Payment Date is not a Business Day within the meaning of Section 2.05(C) and such Redemption Date
occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid interest on Notes to,
but excluding, such Interest Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day
to Holders at of the Close of Business on the immediately preceding Regular Record Date; and (y) the Redemption Price will
include interest on Notes to be redeemed from, and including, such Interest Payment Date.

 

(F)          Redemption
Notice. To call any Notes for Redemption, the Company must (x) send to each applicable Holder of such Notes, the Trustee
and the Paying Agent a written notice of such Redemption (a “Redemption Notice”) and (y) substantially
contemporaneously therewith, issue a press release through such national newswire service as the Company then uses containing the
information set forth in the Redemption Notice.

 

Such Redemption Notice
must state:

 

(i)            that
the Notes have been called for Redemption, briefly describing the Company’s Redemption right under the Indenture;

 

    	 	- 33 -	 

     

    

 

(ii)           the
Redemption Date for such Redemption;

 

(iii)          the
Redemption Price per $1,000 principal amount of Notes for such Redemption (and, if the Redemption Date is after a Regular Record
Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to
the proviso to Section 4.03(E));

 

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

 

(v)            that
Notes called for Redemption may be converted at any time before the Close of Business on the Business Day immediately before the
Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such
time as the Company pays such Redemption Price in full);

 

(vi)           the
Conversion Rate in effect on the Redemption Notice Date for such Redemption and a description and quantification of any adjustments
to the Conversion Rate that may result from such Redemption (including pursuant to Section 5.07);

 

(vii)          the
Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after such Redemption Notice
Date and before such Redemption Date; and

 

(viii)         the
CUSIP and ISIN numbers, if any, of the Notes.

 

On or before the Redemption
Notice Date, the Company will send a copy of such Redemption Notice to the Trustee and the Paying Agent. If the Trustee will send
the Redemption Notice to Holders, the Company will send notice of such redemption to the Trustee at least three (3) Business
Days prior to the Redemption Notice Date.

 

(G)         Selection
and Conversion of Notes to Be Redeemed in Part. If less than all Notes then outstanding are called for Redemption, then:

 

(i)             the
Notes to be redeemed will be selected by the Company as follows: (1) in the case of Global Notes, in accordance with the Depositary
Procedures; and (2) in the case of Physical Notes, pro rata, by lot or by such other method the Company considers fair and
appropriate; and

 

(ii)            if
only a portion of a Note is subject to Redemption and such Note is converted in part, then the converted portion of such Note will
be deemed to be from the portion of such Note that was subject to Redemption.

 

(H)          Payment
of the Redemption Price. Without limiting the Company’s obligation to deposit the Redemption Price by the time proscribed
by Section 3.01(B), the Company will cause the Redemption Price for a Note subject to Redemption to be paid to the
Holder thereof on or before the applicable Redemption Date. For the avoidance of doubt, interest payable pursuant to the proviso
to Section 4.03(E) on any Note (or portion thereof) subject to Redemption must be paid pursuant to such proviso.

 

    	 	- 34 -	 

     

    

 

 

(I)            Special
Provisions for Partial Calls. If the Company elects to redeem less than all of the outstanding Notes pursuant to this Section 4.03,
and the Holder of any Note, or any owner of a beneficial interest in any Global Note, is reasonably not able to determine, before
the Close of Business on the fifty-second (52nd) Scheduled Trading Day (or, if, in accordance with Section 5.03(A)(iii),
the Company has elected to settle all conversions of Notes with a Conversion Date that occurs on or after the Redemption Notice
Date for such Redemption and on or before the Business Day immediately before the Redemption Date by Physical Settlement, the tenth
(10th) calendar day) immediately before the Redemption Date for such Redemption, whether such Note or beneficial interest, as applicable,
is to be redeemed pursuant to such Redemption, then such Holder or owner, as applicable, will be entitled to convert such Note
or beneficial interest, as applicable, at any time before the Close of Business on the Business Day immediately before such Redemption
Date, and each such conversion will be deemed to be of a Note called for Redemption for purposes of this Section 4.03
and Sections 5.01(C)(i)(4) and 5.07.

Section
5.01. Right to

(B)           Conversions
in Part. Subject to the terms of the Indenture, Notes may be converted in part, but only in Authorized Denominations. Provisions
of this Article 5 applying to the conversion of a Note in whole will equally apply to conversions of a permitted portion
of a Note.

 

(C)          When
Notes May Be Converted.

 

(i)            Generally.
Subject to Section 5.01(C)(ii), a Note may be converted only in the following circumstances:

 

(1)           Conversion
upon Satisfaction of Common Stock Sale Price Condition. A Holder may convert its Notes during any calendar quarter commencing
after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the Last Reported Sale
Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price for each of at least twenty
(20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the last
Trading Day of the immediately preceding calendar quarter. The Company will determine at the beginning of each calendar quarter
commencing after the quarter ending September 30, 2020 whether the Notes may be surrendered for conversion in accordance with
this clause and will notify the Holders of the Notes, the Trustee and the Conversion Agent if the Notes become convertible in accordance
with this clause, provided that failure to give such notice will not be considered a Default or form the basis for an Event of
Default for any purpose under this Indenture.

 

    	 	- 35 -	 

     

    

 

(2)           Conversion
upon Satisfaction of Note Trading Price Condition. A Holder may convert its Notes during the five (5) consecutive Business
Days immediately after any five (5) consecutive Trading Day period (such five (5) consecutive Trading Day period, the
“Measurement Period”) if the Trading Price per $1,000 principal amount of Notes, as determined following a request
by a Holder in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was less than ninety-eight
percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate
on such Trading Day. The condition set forth in the preceding sentence is referred to in the Indenture as the “Trading
Price Condition.” Neither the Trustee nor any agent will have any obligation to make any calculation or to determine
whether the Notes may be surrendered for conversion, or to notify the Company, the Depositary or any Holder if the Notes have become
convertible.

 

The Trading Price will be determined
by the Bid Solicitation Agent pursuant to this Section 5.01(C)(i)(2) and the definition of “Trading Price.”
The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless the
Company has requested such determination in writing, and the Company will have no obligation to make such request (or seek bids
itself) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes
would be less than ninety-eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock and the
Conversion Rate. If a Holder provides such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct
the Bid Solicitation Agent to, determine the Trading Price of the Notes beginning on the next Trading Day and on each successive
Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety-eight percent (98%)
of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading
Day. If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders, the Trustee and
the Conversion Agent of the same within one Business Day following the Trading Day on which such Trading Price Condition is met.
If, on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal
amount of Notes is greater than or equal to ninety-eight percent (98%) of the product of the Last Reported Sale Price per share
of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will promptly notify the Holders,
the Trustee and the Conversion Agent of the same, and thereafter, neither the Company nor the Bid Solicitation Agent will be required
to solicit bids again until another qualifying request is made as provided above.

 

(3)            Conversion
upon Specified Corporate Events.

 

(a)           Certain
Distributions. If the Company elects to:

 

(I)            distribute,
to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued pursuant to a stockholder
rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence of a
triggering event, except that such rights will be deemed to be distributed under this clause (I) upon their separation
from the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than forty-five
(45) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per
share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced (determined in
the manner set forth in the third paragraph of Section 5.05(A)(ii)); or

 

    	 	- 36 -	 

     

    

 

(II)            distribute,
to all or substantially all holders of Common Stock, assets or securities of the Company or rights to purchase the Company’s
securities, which distribution per share of Common Stock has a value, as reasonably determined by the Board of Directors, exceeding
ten percent (10%) of the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before the date such
distribution is announced,

 

then, in either case, (x) the
Company will send notice of such distribution, and of the related right to convert Notes, to Holders, the Trustee and the Conversion
Agent at least fifty-five (55) Scheduled Trading Days before the Ex-Dividend Date for such distribution; and (y) once the
Company has sent such notice, Holders may convert their Notes at any time until the earlier of the Close of Business on the Business
Day immediately before such Ex-Dividend Date and the Company’s announcement that such distribution will not take place.

 

(b)            Certain
Corporate Events. If a Fundamental Change, Make-Whole Fundamental Change (other than a Make-Whole Fundamental Change pursuant
to clause (B) of the definition thereof) or Common Stock Change Event occurs, then, in each case, Holders may convert
their Notes at any time from, and including, the effective date of such transaction or event to, and including, the thirty-fifth
(35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change, to, but excluding,
the related Fundamental Change Repurchase Date); provided, however, that if the Company fails to provide the notice
referred to in the immediately following sentence by such effective date, then the last day on which the Notes are convertible
pursuant to this sentence will be extended by the number of Business Days from, and including, such effective date to, but excluding,
the date the Company provides such notice. No later than such effective date, the Company will send notice to the Holders, the
Trustee and the Conversion Agent of such transaction or event, such effective date and the related right to convert Notes.

 

    	 	- 37 -	 

     

    

 

(4)           Conversion
upon Redemption. If the Company calls any Note for Redemption, then the Holder of such Note may convert such Note at any time
before the Close of Business on the Business Day immediately before the related Redemption Date (or, if the Company fails to pay
the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price
in full).

 

(5)           Conversions
During Free Convertibility Period. A Holder may convert its Notes at any time from, and including, November 17, 2025 until
the Close of Business on the second (2nd) Scheduled Trading Day immediately before the Maturity Date.

 

For the avoidance of doubt, the
Notes may become convertible pursuant to any one or more of the preceding sub-paragraphs of this Section 5.01(C)(i) and
the Notes ceasing to be convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will not
preclude the Notes from being convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i). Neither the
Trustee nor any Agent will have any obligation to (i) monitor the Last Reported Sale Price, make any calculation or determine
whether the Notes may be surrendered for conversion, or (ii) notify the Company, the Depositary or any Holders of the Notes
if the Notes have become convertible.

 

(ii)           Limitations
and Closed Periods. Notwithstanding anything to the contrary in the Indenture or the Notes:

 

(1)           Notes
may be surrendered for conversion only after the Open of Business and before the Close of Business on a day that is a Business
Day;

 

(2)           in
no event may any Note be converted after the Close of Business on the second (2nd) Scheduled Trading Day immediately before the
Maturity Date;

 

(3)           if
the Company calls any Note for Redemption pursuant to Section 4.03, then the Holder of such Note may not convert such
Note after the Close of Business on the Business Day immediately before the applicable Redemption Date, except to the extent the
Company fails to pay the Redemption Price for such Note in accordance with the Indenture; and

 

(4)           if
a Fundamental Change Repurchase Notice is validly delivered pursuant to Section 4.02(F) with respect to any Note,
then such Note may not be converted, except to the extent (a) such Note is not subject to such notice; (b) such notice
is withdrawn in accordance with Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase
Price for such Note in accordance with the Indenture.

Section 5.02. Conversion
Procedures.

 

(A)          Generally.

 

(i)            Global
Notes. To convert a beneficial interest in a Global Note that is convertible pursuant to Section 5.01(C), the owner
of such beneficial interest must (1) comply with the Depositary Procedures for converting such beneficial interest (at which
time such conversion will become irrevocable); and (2) pay any amounts due pursuant to Section 5.02(D) or
Section 5.02(E).

 

(ii)           Physical
Notes. To convert all or a portion of a Physical Note that is convertible pursuant to Section 5.01(C), the Holder
of such Note must (1) complete, manually sign and deliver to the Conversion Agent the conversion notice attached to such Physical
Note or a facsimile of such conversion notice; (2) deliver such Physical Note to the Conversion Agent (at which time such
conversion will become irrevocable); (3) furnish any endorsements and transfer documents that the Company or the Conversion
Agent may require; and (4) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E).

 

(B)          Effect
of Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion thereof), such Note (or such
portion thereof) will be deemed to cease to be outstanding (and, for the avoidance of doubt, no Person will be deemed to be a Holder
of such Note (or such portion thereof) as of the Close of Business on such Conversion Date), except to the extent provided in Section 5.02(D).

 

(C)          Holder
of Record of Conversion Shares. The Person in whose name any share of Common Stock is issuable upon conversion of any Note
will be deemed to become the holder of record of such share as of the Close of Business on (i) the Conversion Date for such
conversion, in the case of Physical Settlement; or (ii) the last VWAP Trading Day of the Observation Period for such conversion,
in the case of Combination Settlement.

 

(D)          Interest
Payable upon Conversion in Certain Circumstances. If the Conversion Date of a Note is after a Regular Record Date and before
the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will
be entitled, notwithstanding such conversion (and, for the avoidance of doubt, notwithstanding anything set forth in the proviso
to this sentence), to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that
would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note
remained outstanding through such Interest Payment Date); and (ii) the Holder surrendering such Note for conversion must deliver
to the Company, at the time of such surrender, an amount of cash equal to the amount of such interest referred to in clause (i) above
(regardless of whether such Holder was the Holder of record as of the Close of Business on such Regular Record Date); provided,
however, that the Holder surrendering such Note for conversion need not deliver such cash (v) if the Company has specified
a Redemption Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment
Date; (w) if such Conversion Date occurs after the Regular Record Date immediately before the Maturity Date; (x) if the
Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or before the Business
Day immediately after such Interest Payment Date; or (y) to the extent of any overdue interest or interest that has accrued
on any overdue interest, to the extent the same exists at the time of conversion with respect to such Note. For the avoidance of
doubt, as a result of, and without limiting the generality of, the foregoing, if a Note is converted with a Conversion Date that
is after the Regular Record Date immediately before the Maturity Date, then the Company will pay, as provided above, the interest
that would have accrued on such Note to, but excluding, the Maturity Date, notwithstanding such conversion. For the avoidance of
doubt, if the Conversion Date of a Note to be converted is on an Interest Payment Date, then the Holder of such Note at the Close
of Business on the Regular Record Date immediately before such Interest Payment Date will be entitled to receive, on such Interest
Payment Date, the unpaid interest that has accrued on such Note to, but excluding, such Interest Payment Date, and such Note, when
surrendered for conversion, need not be accompanied by any cash amount pursuant to the first sentence of this Section 5.02(D).

 

    	 	- 39 -	 

     

    

 

(E)           Taxes
and Duties. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax or duty
due on the issue of any shares of Common Stock upon such conversion; provided, however, that if any tax or duty is
due because such Holder requested such shares to be registered in a name other than such Holder’s name, then such Holder
will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the transfer agent for the Common
Stock may refuse to deliver any such shares to be issued in a name other than that of such Holder.

 

(F)           Conversion
Agent to Notify Company of Conversions. If any Note is submitted for conversion to the Conversion Agent or the Conversion Agent
receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly notify the Company and the Trustee
of such occurrence, together with any other information reasonably requested by the Company.

 

Section 5.03. Settlement
upon Conversion.

 

(A)          Settlement
Method. Upon the conversion of any Note, the Company will settle such conversion by paying or delivering, as applicable and
as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of
fractional shares as provided in Section 5.03(D)(i)(1) (a “Physical Settlement”); (y) solely
cash as provided in Section 5.03(D)(i)(2) (a “Cash Settlement”); or (z) a combination
of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(D)(i)(3) (a
“Combination Settlement”).

 

The Company will have
the right to elect the Settlement Method applicable to any conversion of a Note; provided, however, that:

 

(i)            subject
to clause (iii) below, all conversions of Notes with a Conversion Date that occurs on or after November 17, 2025
will be settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders and the
Conversion Agent no later than the Open of Business on November 17, 2025;

 

(ii)           subject
to clause (iii) below, if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion
Date occurs before November 17, 2025, then the Company will send notice of such Settlement Method to the Holder of such Note
and the Conversion Agent no later than the Close of Business on the Business Day immediately after such Conversion Date;

 

    	 	- 40 -	 

     

    

 

(iii)          notwithstanding
anything to the contrary in clause (i) or (ii) above, if any Notes are called for Redemption, then (1) the
Company will specify, in the related Redemption Notice sent pursuant to Section 4.03(F) (and, in the case of a
Redemption of less than all outstanding Notes, in a notice simultaneously sent to all Holders of Notes not called for Redemption),
the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the related Redemption
Notice Date and before the related Redemption Date; and (2) if such Redemption Date occurs on or after November 17, 2025,
then such Settlement Method must be the same Settlement Method that, pursuant to clause (i) above, applies to all conversions
of Notes with a Conversion Date that occurs on or after November 17, 2025;

 

(iv)          the
Company will use the same Settlement Method for all conversions of Notes with a Conversion Date that occurs on the same day (and,
for the avoidance of doubt, the Company will not be obligated to use the same Settlement Method with respect to conversions of
Notes whose Conversion Dates occur on different days, except as provided in clause (i) or (iii) above);

 

(v)           if
the Company does not timely elect a Settlement Method with respect to the conversion of a Note, then the Company will be deemed
to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not
constitute a Default or Event of Default);

 

(vi)          if
the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the Holder
of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to
be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to timely send such notification will
not constitute a Default or Event of Default); and

 

(vii)         the
Settlement Method will be subject to Sections 4.03(D) and 5.08(A)(2).

 

(B)          The
Company’s Right to Irrevocably Fix the Settlement Method. The Company will have the right, exercisable at its election
by sending notice of such exercise to the Holders (with a copy to the Trustee and the Conversion Agent), to (i) irrevocably
fix the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the date such
notice is sent to Holders; or (ii) irrevocably elect Combination Settlement to apply to all conversions of Notes with a Conversion
Date that occurs on or after the date such notice is sent to Holders, and eliminate a Specified Dollar Amount or range of Specified
Dollar Amounts that will apply to such conversions, provided, in each case, that (w) the Settlement Method(s) so
elected pursuant to clause (i) or (ii) above must be a Settlement Method or Settlement Method(s), as applicable,
that the Company is then permitted to elect (for the avoidance of doubt, including pursuant to, and subject to, the other provisions
of this Section 5.03); (x) no such irrevocable election will affect any Settlement Method theretofore elected
(or deemed to be elected) with respect to any Note pursuant to this Indenture (including pursuant to Section 8.01(G) or
this Section 5.03); (y) upon any such irrevocable election pursuant to clause (i) above, the Default
Settlement Method will automatically be deemed to be set to the Settlement Method so fixed; and (z) upon any such irrevocable
election pursuant to clause (ii) above, the Company will, if needed, simultaneously change the Default Settlement Method
to Combination Settlement with a Specified Dollar Amount that is consistent with such irrevocable election. Such notice, if sent,
must set forth the applicable Settlement Method and expressly state that the election is irrevocable and applicable to all conversions
of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders. For the avoidance of doubt, such
an irrevocable election, if made, will be effective without the need to amend the Indenture or the Notes, including pursuant to
Section 8.01(G) (it being understood, however, that the Company may nonetheless choose to execute such an amendment
at its option).

 

    	 	- 41 -	 

     

    

 

(C)          Requirement
to Publicly Disclose the Fixed or Default Settlement Method. If the Company changes the Default Settlement Method pursuant
to clause (x) of the proviso to the definition of such term or irrevocably fixes the Settlement Method(s) pursuant
to Section 5.03(B), then the Company will either post the Default Settlement Method or fixed Settlement Method(s),
as applicable, on its website or disclose the same in a Current Report on Form 8-K (or any successor form) that is filed with
or furnished to the SEC.

 

(D)          Conversion
Consideration.

 

(i)            Generally.
Subject to Section 5.03(D)(ii) and Section 5.03(D)(iii), the type and amount of consideration (the
“Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be
as follows:

 

(1)           if
Physical Settlement applies to such conversion, a number of shares of Common Stock equal to the Conversion Rate in effect on the
Conversion Date for such conversion;

 

(2)            if
Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each VWAP Trading
Day in the Observation Period for such conversion; or

 

(3)            if
Combination Settlement applies to such conversion, consideration consisting of (a) a number of shares of Common Stock equal
to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such conversion; and (b) an
amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period.

 

(ii)           Cash
in Lieu of Fractional Shares. If Physical Settlement or Combination Settlement applies to the conversion of any Note and the
number of shares of Common Stock deliverable pursuant to Section 5.03(D)(i) upon such conversion is not a whole
number, then such number will be rounded down to the nearest whole number and the Company will deliver, in addition to the other
consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such
fraction and (2) (x) the Daily VWAP on the Conversion Date for such conversion (or, if such Conversion Date is not a
VWAP Trading Day, the immediately preceding VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on
the last VWAP Trading Day of the Observation Period for such conversion, in the case of Combination Settlement.

 

(iii)          Conversion
of Multiple Notes by a Single Holder. If a Holder converts more than one (1) Note on a single Conversion Date, then the
Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and
practicable under, the Depositary Procedures) be computed based on the total principal amount of Notes converted on such Conversion
Date by such Holder.

 

    	 	- 42 -	 

     

    

 

(iv)          Notice
of Calculation of Conversion Consideration. If Cash Settlement or Combination Settlement applies to the conversion of any Note,
then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the
applicable Observation Period and will promptly thereafter send notice to the Trustee and the Conversion Agent of the same and
the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such
determination.

 

(E)           Delivery
of the Conversion Consideration. Except as set forth in Sections 5.05(D) and 5.08(A)(2), the Company will
pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder as follows: (i) if
Cash Settlement or Combination Settlement applies to such conversion, on or before the second (2nd) Business Day immediately after
the last VWAP Trading Day of the Observation Period for such conversion; and (ii) if Physical Settlement applies to such conversion,
on or before the second (2nd) Business Day immediately after the Conversion Date for such conversion; provided, however,
that if Physical Settlement applies to the conversion of any Note with a Conversion Date that is after the Regular Record Date
immediately before the Maturity Date, then, solely for purposes of such conversion, (x) the Company will pay or deliver, as
applicable, the Conversion Consideration due upon such conversion no later than the Maturity Date (or, if the Maturity Date is
not a Business Day, the next Business Day); and (y) the Conversion Date will instead be deemed to be the second (2nd) Business
Day immediately before the Maturity Date.

 

(F)           Deemed
Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a Holder converts a Note,
then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as
provided in Section 5.02(D), the Company’s delivery of the Conversion Consideration due in respect of such conversion
will be deemed to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest,
if any, on, such Note to, but excluding the Conversion Date. As a result, except as provided in Section 5.02(D), any
accrued and unpaid interest on a converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited.
In addition, subject to Section 5.02(D), if the Conversion Consideration for a Note consists of both cash and shares
of the Common Stock, then accrued and unpaid interest that is deemed to be paid therewith will be deemed to be paid first out of
such cash.

 

Section 5.04. Reserve
and Status of Common Stock Issued upon Conversion.

 

(A)          Stock
Reserve. At all times when any Notes are outstanding, the Company will reserve, out of its authorized but unissued and unreserved
shares of Common Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes, assuming
(x) Physical Settlement will apply to such conversion; and (y) the Conversion Rate is increased by the maximum amount
pursuant to which the Conversion Rate may be increased pursuant to Section 5.07.

 

    	 	- 43 -	 

     

    

 

(B)          Status
of Conversion Shares; Listing. Each Conversion Share, if any, delivered upon conversion of any Note will be a newly issued
or treasury share and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any
lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such
Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange,
or quoted on any inter-dealer quotation system, then the Company will cause each Conversion Share, when delivered upon conversion
of any Note, to be admitted for listing on such exchange or quotation on such system.

 

Section
5.05. Adjustments
to the Conversion Rate.

 

(A)          Events
Requiring an Adjustment to the Conversion Rate. The Conversion Rate will be adjusted from time to time as follows:

 

(i)            Stock
Dividends, Splits and Combinations. If the Company issues solely shares of Common Stock as a dividend or distribution on all
or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock
(in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which Section 5.08 will apply),
then the Conversion Rate will be adjusted based on the following formula:

 

 

where:

 

		CR0	= 	the Conversion Rate in effect immediately before
the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately before the Open of Business on
the effective date of such stock split or stock combination, as applicable;

 

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

 

		OS0	=       	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective
date, as applicable, without giving effect to such dividend, distribution, stock split or stock combination; and

 

		OS1	= 	the number of shares of Common Stock outstanding
immediately after giving effect to such dividend, distribution, stock split or stock combination.

 

For the avoidance of doubt, an
adjustment pursuant to this Section 5.05(A)(i) will become effective as set forth in the definition of CR1
above. If any dividend, distribution, stock split or stock combination of the type described in this Section 5.05(A)(i) is
declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board
of Directors determines not to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion
Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced.

 

    	 	- 44 -	 

     

    

 

(ii)           Rights,
Options and Warrants. If the Company distributes, to all or substantially all holders of Common Stock, rights, options or warrants
(other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which the provisions set forth
in Sections 5.05(A)(iii)(1) and 5.05(F) will apply) entitling such holders, for a period of not more than
forty-five (45) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at
a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion
Rate will be increased based on the following formula:

 

 

where:

 

		CR0	=	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;

 

		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		OS	=	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date;

 

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

 

		Y	=	a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options
or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced.

 

For the avoidance of doubt, an
adjustment pursuant to this Section 5.05(A)(ii) will become effective as set forth in the definition of CR1
above. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including
as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion
Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery
of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants. To the extent
such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would
then be in effect had the Ex-Dividend Date for the distribution of such rights, options or warrants not occurred.

 

    	 	- 45 -	 

     

    

 

For purposes of this Section 5.05(A)(ii) and
Section 5.01(C)(i)(3)(a)(I), in determining whether any rights, options or warrants entitle holders of Common Stock
to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale
Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately
before the date of the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable
to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such
rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be
determined by the Board of Directors.

 

(iii)          Spin-Offs
and Other Distributed Property.

 

(1)           Distributions
Other than Spin-Offs. If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets
or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all
or substantially all holders of the Common Stock, excluding:

 

(u)            dividends,
distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required (or would be required without
regard to Section 5.05(C)) pursuant to Section 5.05(A)(i) or 5.05(A)(ii);

 

(v)            dividends
or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is required (or would be required without
regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv);

 

(w)            rights
issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 5.05(F);

 

(x)             Spin-Offs
for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C))
pursuant to Section 5.05(A)(iii)(2);

 

(y)             a
distribution solely pursuant to a tender offer or exchange offer for shares of Common Stock for which an adjustment to the Conversion
Rate is required (or would be required without regard to Section 5.05(C)), pursuant to Section 5.05(A)(v);
and

 

(z)              a
distribution solely pursuant to a Common Stock Change Event, as to which Section 5.08 will apply,

 

    	 	- 46 -	 

     

    

 

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

 

 

 

where:

 

		CR0	=	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;

 

		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		SP	=	the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on,
and including, the Trading Day immediately before such Ex-Dividend Date; and

 

		FMV	=	the fair market value (as determined by the Board of Directors), as of such Ex-Dividend Date, of the shares of Capital Stock,
evidences of indebtedness, assets, property, rights, options or warrants distributed per share of Common Stock pursuant to such
distribution;

 

provided, however,
that if FMV is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each
Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at
the same time and on the same terms as holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness,
assets, property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date,
a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

 

For the avoidance of doubt, an
adjustment pursuant to this Section 5.05(A)(iii)(1) will become effective as set forth in the definition of CR1
above. To the extent such distribution is not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that
would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid.

 

(2)           Spin-Offs.
If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interests, of or relating
to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock (other
than solely pursuant to (i) a Common Stock Change Event, as to which Section 5.08 will apply; or (ii) a tender
offer or exchange offer for shares of Common Stock for which an adjustment to the Conversion Rate is required (or would be required
without regard to Section 5.05(C)), pursuant to Section 5.05(A)(v)), and such Capital Stock or equity interests
are listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange
(a “Spin-Off”), then the Conversion Rate will be increased based on the following formula:

 

    	 	- 47 -	 

     

    

 

 

where:

 

		CR0	=	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Spin-Off Valuation Period
for such Spin-Off;

 

		CR1	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Spin-Off Valuation Period;

 

		FMV	=	the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital Stock or equity interests
distributed in such Spin-Off over the ten (10) consecutive Trading Day period (the “Spin-Off Valuation Period”)
beginning on, and including, such Ex-Dividend Date (such average to be determined as if references to Common Stock in the definitions
of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references to such Capital Stock or equity interests);
and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in
such Spin-Off; and

 

		SP	=	the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the Spin-Off Valuation Period.

 

For the avoidance of doubt, an
adjustment pursuant to this Section 5.05(A)(iii)(2) will become effective as set forth in the definition of CR1
above. Notwithstanding anything to the contrary in this Section 5.05(A)(iii)(2), (i) if any VWAP Trading Day of
the Observation Period for a Note whose conversion will be settled pursuant to Cash Settlement or Combination Settlement occurs
during the Spin-Off Valuation Period for such Spin-Off, then, solely for purposes of determining the Conversion Rate for such VWAP
Trading Day for such conversion, such Spin-Off Valuation Period will be deemed to consist of the Trading Days occurring in the
period from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such VWAP Trading Day; and (ii) if the
Conversion Date for a Note whose conversion will be settled pursuant to Physical Settlement occurs during the Spin-Off Valuation
Period for a Spin-Off, then, solely for purposes of determining the Conversion Consideration due for such conversion, such Spin-Off
Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Ex-Dividend Date
for such Spin-Off to, and including, such Conversion Date.

 

    	 	- 48 -	 

     

    

 

To the extent any dividend or
distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or paid, the Conversion
Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only
the dividend or distribution, if any, actually made or paid.

 

(iv)          Cash
Dividends or Distributions. If any cash dividend or distribution is made to all or substantially all holders of Common Stock,
then the Conversion Rate will be increased based on the following formula:

 

 

where:

 

		CR0	=	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution;

 

		CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		SP	=	the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date; and

 

		D	=	the cash amount distributed per share of Common Stock in such dividend or distribution;

 

provided, however,
that if D is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each
Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution,
at the same time and on the same terms as holders of Common Stock, the amount of cash that such Holder would have received if such
Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record
date.

 

For the avoidance of doubt, an
adjustment pursuant to this Section 5.05(A)(iv) will become effective as set forth in the definition of CR1
above. To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to
the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution,
if any, actually made or paid.

 

    	 	- 49 -	 

     

    

 

 

(v)          Tender
Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange
offer for shares of Common Stock, and the value (determined as of the Expiration Time by the Board of Directors) of the cash and
other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per share
of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders
or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased
based on the following formula:

 

 

where:

 

		CR0	=	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Tender/Exchange Offer
Valuation Period for such tender or exchange offer;

 

		CR1	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Tender/Exchange Offer
Valuation Period;

 

		AC	=	the aggregate value (as determined by the Board of Directors as of the time (the “Expiration Time”) such
tender or exchange offer expires) of all cash and other consideration paid for shares of Common Stock purchased or exchanged in
such tender or exchange offer;

 

		OS0	=	the number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock
accepted for purchase or exchange in such tender or exchange offer);

 

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

 

		SP	=	the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period
(the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading Day immediately after
the Expiration Date;

 

provided, however,
that the Conversion Rate will in no event be adjusted down pursuant to this Section 5.05(A)(v), except to the extent
provided in the immediately following paragraph. For the avoidance of doubt, an adjustment pursuant to this Section 5.05(A)(v) will
become effective as set forth in the definition of CR1 above. Notwithstanding anything to the contrary in this
Section 5.05(A)(v), (i) if any VWAP Trading Day of the Observation Period for a Note whose conversion will be
settled pursuant to Cash Settlement or Combination Settlement occurs during the Tender/Exchange Offer Valuation Period for such
tender or exchange offer, then, solely for purposes of determining the Conversion Rate for such VWAP Trading Day for such conversion,
such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including,
the Trading Day immediately after the Expiration Date for such tender or exchange offer to, and including, such VWAP Trading Day;
and (ii) if the Conversion Date for a Note whose conversion will be settled pursuant to Physical Settlement occurs during
the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely for purposes of determining the Conversion
Consideration for such conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring
in the period from, and including, the Trading Day immediately after the Expiration Date to, and including, such Conversion Date.

 

    	 	- 50 -	 

     

    

 

To the extent such tender or
exchange offer is announced but not consummated (including as a result of the Company being precluded from consummating such tender
or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer
are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been
made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such
tender or exchange offer.

 

(B)          No
Adjustments in Certain Cases.

 

(i)           Where
Holders Participate in the Transaction or Event Without Conversion. Notwithstanding anything to the contrary in Section 5.05(A),
the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring
an adjustment pursuant to Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or
a tender or exchange offer of the type set forth in Section 5.05(A)(v)) if each Holder participates, at the same time
and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event
without having to convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the
product of (i) the Conversion Rate in effect on the related record date; and (ii) the aggregate principal amount (expressed
in thousands) of Notes held by such Holder on such date.

 

(ii)          Certain
Events. The Company will not be required to adjust the Conversion Rate except as provided in Section 5.05 or Section 5.07.
Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account of:

 

(1)          stock
repurchases, including structured or derivative transactions, pursuant to a stock repurchase program approved by the Board of Directors,
in each case that are not tender or exchange offers referred to in Section 5.05(A)(v);

 

(2)          except
as otherwise provided in Section 5.05, the sale of shares of Common Stock for a purchase price that is less than the
market price per share of Common Stock or less than the Conversion Price;

 

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

 

(4)          the
issuance of any shares of Common Stock or options or 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;

 

    	 	- 51 -	 

     

    

 

(5)          the
issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or exchangeable security of the Company
not described in clause (4) above and outstanding as of the Issue Date;

 

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

 

(7)          accrued
and unpaid interest on the Notes.

 

(C)          Adjustment
Deferral. If an adjustment to the Conversion Rate otherwise required by this Article 5 would result in a change
of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5,
the Company may, at its election, defer such adjustment, except that all such deferred adjustments must be given effect immediately
upon the earliest of the following: (i) when all such deferred adjustments would result in a change of at least one percent
(1%) to the Conversion Rate; (ii) the Conversion Date of, or any VWAP Trading Day of an Observation Period for, any Note;
(iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; (iv) the date the Company calls any Notes
for Redemption; and (v) November 17, 2025.

 

(D)          Adjustments
Not Yet Effective. Notwithstanding anything to the contrary in the Indenture or the Notes, if:

 

(i)            a
Note is to be converted pursuant to Physical Settlement or Combination Settlement;

 

(ii)           the
record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to Section 5.05(A) has
occurred on or before the Conversion Date for such conversion (in the case of Physical Settlement) or on or before any VWAP Trading
Day in the Observation Period for such conversion (in the case of Combination Settlement), but an adjustment to the Conversion
Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable;

 

(iii)          the
Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due in respect of such VWAP Trading Day
(in the case of Combination Settlement) includes any whole shares of Common Stock; and

 

(iv)          such
shares are not entitled to participate in such event (because they were not held on the related record date or otherwise),

 

then, solely for purposes of such conversion,
the Company will, without duplication, give effect to such adjustment on such Conversion Date (in the case of Physical Settlement)
or such VWAP Trading Day (in the case of Combination Settlement). In such case, if the date on which the Company is otherwise required
to deliver the consideration due upon such conversion is before the first date on which the amount of such adjustment can be determined,
then the Company will delay the settlement of such conversion until the second (2nd) Business Day after such first date.

 

    	 	- 52 -	 

     

    

 

(E)          Conversion
Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event. Notwithstanding anything to the
contrary in the Indenture or the Notes, if:

 

(i)           a
Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A);

 

(ii)          a
Note is to be converted pursuant to Physical Settlement or Combination Settlement;

 

(iii)         the
Conversion Date for such conversion (in the case of Physical Settlement) or any VWAP Trading Day in the Observation Period for
such conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record
date;

 

(iv)         the
Conversion Consideration due upon such conversion (in the case of Physical Settlement) or due with respect to such VWAP Trading
Day (in the case of Combination Settlement) includes any whole shares of Common Stock based on a Conversion Rate that is adjusted
for such dividend or distribution; and

 

(v)          such
shares would be entitled to participate in such dividend or distribution (including pursuant to Section 5.02(C)),

 

then (x) in the case of Physical Settlement,
such Conversion Rate adjustment will not be given effect for such conversion, and the shares of Common Stock issuable upon such
conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or distribution, but there
will be added, to the consideration otherwise due upon such conversion, the same kind and amount of consideration that would have
been delivered in such dividend or distribution with respect to such shares had such shares been entitled to participate in such
dividend or distribution; and (y) in the case of Combination Settlement, the Conversion Rate adjustment relating to such Ex-Dividend
Date will be made for such conversion in respect of such VWAP Trading Day, but the shares of Common Stock issuable with respect
to such VWAP Trading Day based on such adjusted Conversion Rate will not be entitled to participate in such dividend or distribution.

 

(F)          Stockholder
Rights Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such conversion,
the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to,
and concurrently with the delivery of, the Conversion Consideration otherwise payable under the Indenture upon such conversion,
the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in
which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 5.05(A)(iii)(1) on
account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in
such Section to all holders of the Common Stock, subject to readjustment in accordance with such Section if such rights
expire, terminate or are redeemed.

 

    	 	- 53 -	 

     

    

 

(G)          Limitation
on Effecting Transactions Resulting in Certain Adjustments. The Company will not engage in or be a party to any transaction
or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section 5.07
to an amount that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common
Stock.

 

(H)          Equitable
Adjustments to Prices. Whenever any provision of the Indenture requires the Company to calculate the average of the Last Reported
Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to
the Conversion Rate), or to calculate Daily VWAPs over an Observation Period, the Company will make proportionate adjustments,
if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A)(i) that
becomes effective, or any event requiring such an adjustment to the Conversion Rate where the Ex-Dividend Date or effective date,
as applicable, of such event occurs, at any time during such period or Observation Period, as applicable.

 

(I)           Calculation
of Number of Outstanding Shares of Common Stock. For purposes of Section 5.05(A), the number of shares of Common
Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions
of shares of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company
pays any dividend or makes any distribution on shares of Common Stock held in its treasury).

 

(J)           Calculations. All calculations with respect to the
Conversion Rate and adjustments thereto will be made to the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths
rounded upward).

 

(K)          Notice
of Conversion Rate Adjustments. Upon the effectiveness of any adjustment to the Conversion Rate pursuant to the Indenture,
the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing (i) a brief description
of the transaction or other event on account of which such adjustment was made; (ii) the Conversion Rate in effect immediately
after such adjustment; and (iii) the effective time of such adjustment. In the absence of such a notice, each of the Trustee
and the Conversion Agent may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion
Rate of which it has knowledge remains in effect

 

(L)          Compliance
with Stock Exchange Listing Standards. Notwithstanding anything to the contrary, the Company will not engage in any transaction,
or take any action, that would require an increase to the Conversion Rate pursuant to Section 5.05 without complying
with the applicable stockholder approval rules of The Nasdaq Global Market.

 

Section 5.06.      Voluntary
Adjustments.

 

(A)         Generally.
To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but is not required to)
increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in
the best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on holders of Common Stock
or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common
Stock or any similar event; (ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) such
increase is irrevocable during such period.

 

    	 	- 54 -	 

     

    

 

(B)          Notice
of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to this Section 5.06,
then, no later than the first Business Day of the related twenty (20) Business Day period referred to in Section 5.06(A),
the Company will send notice to each Holder (with a copy to the Trustee and the Conversion Agent) of such increase, the amount
thereof and the period during which such increase will be in effect.

 

Section 5.07.      Adjustments
to the Conversion Rate in Connection with a Make-Whole Fundamental Change.

 

(A)         Generally.
If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note occurs during the related Make-Whole
Fundamental Change Conversion Period, then, subject to this Section 5.07, the Conversion Rate applicable to such conversion
will be increased by a number of shares (the “Additional Shares”) set forth in the table below corresponding
(after interpolation as provided in, and subject to, the provisions below) to the Make-Whole Fundamental Change Effective Date
and the Stock Price of such Make-Whole Fundamental Change:

 

	 	 	Stock
    Price	 
	Make-Whole

If such Make-Whole
Fundamental Change Effective Date or Stock Price is not set forth in the table above, then:

 

(i)           if
such Stock Price is between two Stock Prices in the table above or the Make-Whole Fundamental Change Effective Date is between
two dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between
the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table or the earlier and later dates in
the table above, as applicable, based on a 365- or 366-day year, as applicable; and

 

(ii)          if
the Stock Price is greater than $110.00 (subject to adjustment in the same manner as the Stock Prices set forth in the column headings
of the table above are adjusted pursuant to Section 5.07(B)), or less than $14.50 (subject to adjustment in the same
manner), per share, then no Additional Shares will be added to the Conversion Rate.

 

Notwithstanding anything
to the contrary in the Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds 68.9655
shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at
the same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant to Section 5.05(A).

 

    	 	- 55 -	 

     

    

 

For the avoidance of
doubt, but subject to Section 4.03(I), (x) the sending of a Redemption Notice will constitute a Make-Whole Fundamental
Change only with respect to the Notes called for Redemption pursuant to such Redemption Notice, and not with respect to any other
Notes; and (y) the Conversion Rate applicable to the Notes not so called for Redemption will not be subject to increase pursuant
to this Section 5.07 on account of such Redemption Notice.

 

(B)          Adjustment
of Stock Prices and Additional Shares. The Stock Prices in the first row (i.e., the column headers) of the table set
forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events
for which, the Conversion Price is adjusted as a result of the operation of Section 5.05(A). The numbers of Additional
Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time
and for the same events for which, the Conversion Rate is adjusted pursuant to Section 5.07(A).

 

(C)          Notice
of the Occurrence of a Make-Whole Fundamental Change. The Company will notify the Holders, the Trustee and the Conversion Agent
of each Make-Whole Fundamental Change occurring pursuant to clause (A) of the definition thereof in accordance with
Section 5.01(C)(i)(3)(b).

 

(D)         Settlement
of Cash Make-Whole Fundamental Changes. For the avoidance of doubt, if holders of Common Stock receive solely cash in a Make-Whole
Fundamental Change, then, pursuant to Section 5.08, conversions of Notes will thereafter be settled no later than the
second (2nd) Business Day after the relevant Conversion Date.

 

Section 5.08.      Effect
of Common Stock Change Event.

 

(A)         Generally.
If there occurs any:

 

(i)           recapitalization,
reclassification or change of the Common Stock (other than (x) changes solely resulting from a subdivision or combination
of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock
splits and stock combinations that do not involve the issuance of any other series or class of securities);

 

(ii)          consolidation,
merger, combination or binding or statutory share exchange involving the Company; or

 

(iii)         sale,
lease or other transfer of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any
Person,

 

and, as a result of which, the Common Stock
is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other property, or
any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash
or property, the “Reference Property,” and the amount and kind of Reference Property that a holder of one (1) share
of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement
not to issue or deliver a fractional portion of any security or other property), a “Reference Property Unit”),
then, notwithstanding anything to the contrary in the Indenture or the Notes,

 

    	 	- 56 -	 

     

    

 

(1)          from
and after the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon conversion of any
Note, and the conditions to any such conversion, will be determined in the same manner as if each reference to any number of shares
of Common Stock in this Article 5 (or in any related definitions) were instead a reference to the same number of Reference
Property Units; (II) for purposes of Section 4.03, each reference to any number of shares of Common Stock in such
Section (or in any related definitions) will instead be deemed to be a reference to the same number of Reference Property
Units; and (III) for purposes of the definition of “Fundamental Change” and “Make-Whole Fundamental Change,”
the terms “Common Stock” and “common equity” will be deemed to mean the common equity (including depositary
receipts representing common equity), if any, forming part of such Reference Property;

 

(2)          if
such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Physical Settlement in respect
of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event and will pay the
cash due upon such conversions no later than the tenth (10th) Business Day after the relevant Conversion Date; and

 

(3)          for
these purposes, (i) the Daily VWAP of any Reference Property Unit or portion thereof that consists of a class of common equity
securities will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg
page for such class of securities in such definition; and (ii) the Daily VWAP of any Reference Property Unit or portion
thereof that does not consist of a class of common equity securities, and the Last Reported Sale Price of any Reference Property
Unit or portion thereof that does not consist of a class of securities, will be the fair value of such Reference Property Unit
or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars,
the face amount thereof).

 

If the Reference Property
consists of more than a single type of consideration to be determined based in part upon any form of stockholder election, then
the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration
actually received, per share of Common Stock, by the holders of Common Stock. The Company will notify Holders (with a copy to the
Trustee and the Conversion Agent) of such weighted average as soon as practicable after such determination is made.

 

At or before the effective
time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such
Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture
pursuant to Section 8.01(F), which supplemental indenture will (x) provide for subsequent conversions of Notes
in the manner set forth in this Section 5.08; (y) provide for subsequent adjustments to the Conversion Rate pursuant
to Section 5.07(A) in a manner consistent with this Section 5.08; and (z) contain such other
provisions as the Company reasonably determines are appropriate to preserve the economic interests of the Holders and to give effect
to the provisions of this Section 5.08(A). If the Reference Property includes shares of stock or other securities or
assets of a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such
supplemental indenture will contain such additional provisions the Company reasonably determines are appropriate to preserve the
economic interests of the Holders.

 

    	 	- 57 -	 

     

    

 

(B)          Notice
of Common Stock Change Events. The Company will provide notice of each Common Stock Change Event in the manner provided in
Section 5.01(C)(i)(3)(b).

 

(C)          Compliance
Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent with this Section 5.08.

 

Article 6.     Successors

 

Section 6.01.      When
the Company May Merge, Etc.

 

(A)         Generally.
The Company will not consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series
of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to another Person
(a “Business Combination Event”), unless:

 

(i)           the
resulting, surviving or transferee Person either (x) is the Company or (y) if not the Company, is a corporation (the
“Successor Corporation”) duly organized and existing under the laws of the United States of America, any State
thereof or the District of Columbia that expressly assumes (by executing and delivering to the Trustee, at or before the effective
time of such Business Combination Event, a supplemental indenture in form satisfactory to the Trustee pursuant to Section 8.01(E))
all of the Company’s obligations under the Indenture and the Notes; and

 

(ii)          immediately
after giving effect to such Business Combination Event, no Default or Event of Default will have occurred and be continuing.

 

(B)          Delivery
of Officer’s Certificate and Opinion of Counsel to the Trustee. Before the effective time of any Business Combination
Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such
Business Combination Event (and, if applicable, the related supplemental indenture) comply with Section 6.01(A); and
(ii) all conditions precedent to such Business Combination Event provided in the Indenture have been satisfied.

 

Section 6.02.      Successor
Corporation Substituted.

 

At the effective time
of any Business Combination Event that complies with Section 6.01, the Successor Corporation (if not the Company) will
succeed to, and may exercise every right and power of, the Company under the Indenture and the Notes with the same effect as if
such Successor Corporation had been named as the Company in the Indenture and the Notes, and, except in the case of a lease, the
predecessor Company will be discharged from its obligations under the Indenture and the Notes.

Article 7.     Defaults
and Remedies

 

Section 7.01.      Events
of Default.

 

(A)         Definition
of Events of Default. “Event of Default” means the occurrence of any of the following:

 

(i)           a
default in the payment when due (whether at maturity, upon Redemption or Repurchase Upon Fundamental Change or otherwise) of the
principal of, or the Redemption Price or Fundamental Change Repurchase Price for, any Note;

 

(ii)          a
default in the payment when due of interest on any Note that continues for thirty (30) days;

 

(iii)         the
Company’s failure to deliver, when required by the Indenture, a Fundamental Change Notice, or a notice pursuant to Section 5.01(C)(i)(3)(b) if
(in the case of any notice other than a notice pursuant to Section 5.01(C)(i)(3)(b)) such failure is not cured within
three (3) Business Days after its occurrence;

 

(iv)         a
default in the Company’s obligation to convert a Note in accordance with Article 5 upon the exercise of the conversion
right with respect thereto, and such default is not cured within three (3) Business Days after its occurrence;

 

(v)          a
default in the Company’s obligations under Article 6;

 

(vi)         a
default in any of the Company’s obligations or agreements under the Indenture or the Notes (other than a default set forth
in clause (i), (ii), (iii), (iv) or (v) of this Section 7.01(A)) where
such default is not cured or waived within sixty (60) days after notice to the Company by the Trustee, or to the Company and the
Trustee by Holders of at least twenty-five percent (25%) of the aggregate principal amount of Notes then outstanding, which notice
must specify such default, demand that it be remedied and state that such notice is a “Notice of Default”;

 

(vii)        a
default by the Company or any of its Subsidiaries with respect to any one or more mortgages, agreements or other instruments under
which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least twenty-five
million dollars ($25,000,000) (or its foreign currency equivalent) in the aggregate of the Company or any of its Subsidiaries,
whether such indebtedness exists as of the Issue Date or is thereafter created, where such default:

 

(1)          constitutes
a failure to pay the principal of such indebtedness when due and payable at its stated maturity, upon required repurchase, upon
declaration of acceleration or otherwise, in each case after the expiration of any applicable grace period; or

 

    	 	- 59 -	 

     

    

 

(2)          results
in such indebtedness becoming or being declared due and payable before its stated maturity,

 

unless, in each case, such principal
is paid (or the indebtedness with respect thereto is discharged) or such payment of such principal is waived or is otherwise no
longer due and payable or such acceleration is rescinded or annulled, in which case the Event of Default by reason of the failure
to pay such principal when due will (unless the Notes have theretofore been accelerated) be deemed not to have occurred;

 

(viii)       one
or more final judgments being rendered against the Company or any of its Subsidiaries for the payment of at least twenty-five million
dollars ($25,000,000) (or its foreign currency equivalent) in the aggregate (excluding any amounts covered by insurance), where
such judgment is not discharged or stayed within sixty (60) days after (i) the date on which the right to appeal the same
has expired, if no such appeal has commenced; or (ii) the date on which all rights to appeal have been extinguished;

 

(ix)          the
Company or any of its Significant Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either:

 

(1)          commences
a voluntary case or proceeding;

 

(2)          consents
to the entry of an order for relief against it in an involuntary case or proceeding;

 

(3)          consents
to the appointment of a custodian of it or for any substantial part of its property;

 

(4)          makes
a general assignment for the benefit of its creditors;

 

(5)          takes
any comparable action under any foreign Bankruptcy Law; or

 

(6)          generally
is not paying its debts as they become due; or

 

(x)           a
court of competent jurisdiction enters an order or decree under any Bankruptcy Law that either:

 

(1)          is
for relief against Company or any of its Significant Subsidiaries in an involuntary case or proceeding;

 

(2)          appoints
a custodian of the Company or any of its Significant Subsidiaries, or for any substantial part of the property of the Company or
any of its Significant Subsidiaries;

 

(3)          orders
the winding up or liquidation of the Company or any of its Significant Subsidiaries; or

 

(4)          grants
any similar relief under any foreign Bankruptcy Law,

 

and, in each case under this
Section 7.01(A)(x), such order or decree remains unstayed and in effect for at least sixty (60) days.

 

    	 	- 60 -	 

     

    

 

(B)          Cause
Irrelevant. Each of the events set forth in Section 7.01(A) will constitute an Event of Default regardless
of the cause thereof or whether voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or
order of any court or any order, rule or regulation of any administrative or governmental body.

 

Section 7.02.      Acceleration.

 

(A)         Automatic
Acceleration in Certain Circumstances. If an Event of Default set forth in Section 7.01(A)(ix) or 7.01(A)(x) occurs
with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount
of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any
declaration or further action or notice by any Person, including the Trustee or any Holder.

 

(B)          Optional
Acceleration. Subject to Section 7.03, if an Event of Default (other than an Event of Default set forth in Section 7.01(A)(ix) or
7.01(A)(x) with respect to the Company and not solely with respect to a Significant Subsidiary of the Company) occurs
and is continuing, then the Trustee, by written notice to the Company, or Holders of at least twenty-five percent (25%) of the
aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount
of, and all accrued and unpaid interest on, all of the Notes then outstanding to become due and payable immediately.

 

(C)          Rescission
of Acceleration. Notwithstanding anything to the contrary in the Indenture or the Notes, the Holders of a majority in aggregate
principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind
any acceleration of the Notes and its consequences if (i) such rescission would not conflict with any judgment or decree of
a court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal of, or interest
on, the Notes that has become due solely because of such acceleration) have been cured or waived. No such rescission will affect
any subsequent Default or impair any right consequent thereto.

 

Section 7.03.      Sole
Remedy for a Failure to Report.

 

(A)         Generally.
Notwithstanding anything to the contrary in the Indenture or the Notes, the Company may elect that the sole remedy for any Event
of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the
Company’s failure to comply with Section 3.02 (including Section 314(a)(1) of the Trust Indenture Act)
will, for each of the first one hundred and eighty (180) calendar days on which a Reporting Event of Default has occurred and is
continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an election, then
(i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant Reporting Event
of Default from, and including, the one hundred and eighty-first (181st) calendar day on which a Reporting Event of Default has
occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special
Interest will cease to accrue on any Notes from, and including, such one hundred and eighty-first (181st) calendar day (it being
understood that interest on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.05(B)).

 

    	 	- 61 -	 

     

    

 

(B)          Amount
and Payment of Special Interest. Any Special Interest that accrues on a Note pursuant to Section 7.03(A) will
be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal
to one quarter of one percent (0.25%) of the principal amount thereof for the first ninety (90) days on which Special Interest
accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof. Special
Interest will accrue at the rates set forth in the preceding sentence during the continuance of a reporting Event of Default regardless
of the number of reporting Events of Default giving rise to the accrual of Special Interest. For the avoidance of doubt, any Special
Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note.

 

(C)          Notice
of Election. To make the election set forth in Section 7.03(A), the Company must send to the Holders, the Trustee
and the Paying Agent, on or before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly
describes the report(s) that the Company failed to file with the SEC; (ii) states that the Company is electing that the
sole remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) briefly describes the
periods during which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject
to acceleration on account of such Reporting Event of Default.

 

(D)         Notice
to Trustee and Paying Agent; Trustee’s Disclaimer. If Special Interest accrues on any Note, then, no later than five
(5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver an Officer’s
Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Special Interest on such
Note on such date of payment; and (ii) the amount of such Special Interest that is payable on such date of payment. The Trustee
will have no duty to determine whether any Special Interest is payable or the amount thereof.

 

(E)          No
Effect on Other Events of Default. No election pursuant to this Section 7.03 with respect to a Reporting Event
of Default will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other
Reporting Event of Default.

 

Section 7.04.      Other Remedies.

 

(A)         Trustee
May Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue any available remedy
to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of the Indenture
or the Notes.

 

(B)          Procedural
Matters. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them
in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default
will not impair the right or remedy or constitute a waiver of, or acquiescence in, such Event of Default. All remedies will be
cumulative to the extent permitted by law.

 

    	 	- 62 -	 

     

    

 

Section 7.05.      Waiver
of Past Defaults.

 

An Event of Default
pursuant to clause (i), (ii), (iv) or (vi) of Section 7.01(A) (that, in
the case of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent
of each affected Holder), and a Default that could lead to such an Event of Default, can be waived only with the consent of each
affected Holder. Each other Default or Event of Default may be waived, on behalf of all Holders, by the Holders of a majority in
aggregate principal amount of the Notes then outstanding. If an Event of Default is so waived, then it will cease to exist. If
a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur.
However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any right arising therefrom.

 

Section 7.06.      Control by Majority.

 

Holders of a majority
in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any proceeding
for exercising 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, the Indenture or the Notes, or that, subject to Section 10.01, the
Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the
Trustee is offered security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that
may result from the Trustee’s following such direction.

 

Section 7.07.      Limitation on Suits.

 

No Holder may pursue
any remedy with respect to the Indenture or the Notes (except to enforce (x) its rights to receive the principal of, or the
Redemption Price or Fundamental Change Repurchase Price for, or interest on, any Notes; or (y) the Company’s obligations
to convert any Notes pursuant to Article 5), unless:

 

(A)         such
Holder has previously delivered to the Trustee notice that an Event of Default is continuing;

 

(B)          Holders
of at least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a request to the Trustee
to pursue such remedy;

 

(C)          such
Holder or Holders offer and, if requested, provide to the Trustee security and indemnity satisfactory to the Trustee against any
loss, liability or expense to the Trustee that may result from the Trustee’s following such request;

 

(D)         the
Trustee does not comply with such request within sixty (60) calendar days after its receipt of such request and such offer of security
or indemnity; and

 

(E)          during
such sixty (60) calendar day period, Holders of a majority in aggregate principal amount of the Notes then outstanding do not deliver
to the Trustee a direction that is inconsistent with such request.

 

A Holder of a Note
may not use the Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it
being understood that the Trustee will not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial
to any other Holder).

 

    	 	- 63 -	 

     

    

 

Section 7.08.      Absolute
Right of Holders to Receive Payment and Conversion Consideration and to Institute Suit for the Enforcement of Such Right.

 

Notwithstanding anything
to the contrary in the Indenture or the Notes, the right of each Holder of a Note to receive payment or delivery, as applicable,
of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or any interest on, or the Conversion
Consideration due pursuant to Article 5 upon conversion of, such Note on or after the respective due dates therefor
provided in the Indenture and the Notes, or to bring suit for the enforcement of any such payment or delivery after such respective
due dates, will not be impaired or affected without the consent of such Holder.

 

Section 7.09.      Collection
Suit by Trustee.

 

The Trustee will have
the right, upon the occurrence and continuance of an Event of Default pursuant to clause (i), (ii) or (iv) of
Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the
total unpaid or undelivered principal of, or Redemption Price or Fundamental Change Repurchase Price for, or interest on, or Conversion
Consideration due pursuant to Article 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any
Default Interest on any Defaulted Amounts, and such further amounts sufficient to cover the costs and expenses of collection, including
compensation provided for in Section 10.06.

 

Section 7.10.      Trustee
May File Proofs of Claim.

 

The Trustee has the
right to (A) 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 and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the
Notes) or its creditors or property and (B) collect, receive and distribute any money or other property payable or deliverable
on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee
consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable
compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to
the Trustee pursuant to Section 10.06. To the extent that the payment of any such compensation, expenses, disbursements,
advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured
by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders
may be entitled to receive in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise).
Nothing in the Indenture will be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such proceeding.

(H)            evidence
or provide for the acceptance of the appointment, under the Indenture, of a successor Trustee;

Section 8.02.       With
the Consent of Holders.

 

(A)            Generally.
Subject to Sections 8.01, 7.05 and 7.08 and the immediately following sentence, the Company and the Trustee
may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement
the Indenture or the Notes or waive compliance with any provision of the Indenture or the Notes. Notwithstanding anything to the
contrary in the foregoing sentence, but subject to subject to Section 8.01, without the consent of each affected Holder,
no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may:

 

(i)               reduce
the principal, or extend the stated maturity, of any Note;

 

(ii)              reduce
the Redemption Price or Fundamental Change Repurchase Price for any Note or change the times at which, or the circumstances under
which, the Notes may or will be redeemed or repurchased by the Company;

 

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

 

(iv)            make
any change that adversely affects the conversion rights of any Note;

 

(v)             impair
the rights of any Holder set forth in Section 7.08 (as such section is in effect on the Issue Date);

 

(vi)            change
the ranking of the Notes;

 

(vii)           make
any note payable in money, or at a place of payment, other than that stated in the Indenture or the Note;

 

(viii)          reduce
the amount of Notes whose Holders must consent to any amendment, supplement, waiver or other modification; or

 

(ix)             make
any direct or indirect change to any amendment, supplement, waiver or modification provision of the Indenture or the Notes that
requires the consent of each affected Holder.

 

For the avoidance of
doubt, pursuant to clauses (i), (ii), (iii) and (iv) of this Section 8.02(A),
no amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may change
the amount or type of consideration due on any Note (whether on an Interest Payment Date, Redemption Date, Fundamental Change Repurchase
Date or the Maturity Date or upon conversion, or otherwise), or the date(s) or time(s) such consideration is payable
or deliverable, as applicable, without the consent of each affected Holder.

 

(B)            Holders
Need Not Approve the Particular Form of any Amendment. A consent of any Holder pursuant to this Section 8.02
need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver.

 

    	 	- 67 -	 

     

    

 

Section 8.03.       Notice
of Amendments, Supplements and Waivers.

 

Promptly after any
amendment, supplement or waiver pursuant to Section 8.01 or 8.02 becomes effective, the Company will (or, in
the case of an amendment or supplement pursuant to Section 8.01(I), the Company may, at its election) send to the Holders
and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable detail and (B) states
the effective date thereof. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity
of such amendment, supplement or waiver.

 

Section 8.04.       Revocation,
Effect and Solicitation of Consents; Special Record Dates; Etc.

 

(A)            Revocation
and Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver will bind (and constitute the
consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting
Holder’s Note, subject to the right of any Holder of a Note to revoke (if not prohibited pursuant to Section 8.04(B))
any such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement
or waiver becomes effective.

 

(B)            Special
Record Dates. The Company may, but is not required to, fix a record date for the purpose of determining the Holders entitled
to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8.
If a record date is fixed, then, only Persons who are Holders as of such record date (or their duly designated proxies) will be
entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons
continue to be Holders after such record date; provided, however, that no such consent will be valid or effective
for more than one hundred and twenty (120) calendar days after such record date.

 

(C)            Solicitation
of Consents. For the avoidance of doubt, each reference in the Indenture or the Notes to the consent of a Holder will be deemed
to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes.

 

(D)            Effectiveness
and Binding Effect. Each amendment, supplement or waiver pursuant to this Article 8 will become effective in accordance
with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder
of such Note (or such portion).

 

Section 8.05.       Notations
and Exchanges.

 

If any amendment, supplement
or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder of such Note
to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note
and return such Note to such Holder. Alternatively, at its discretion, the Company may, in exchange for such Note, issue, execute
and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Note that reflects
the changed terms. The failure to make any appropriate notation or issue a new Note pursuant to this Section 8.05 will
not impair or affect the validity of such amendment, supplement or waiver.

 

    	 	- 68 -	 

     

    

 

Section 8.06.       Trustee
to Execute Supplemental Indentures.

 

The Trustee will execute
and deliver any amendment or supplemental indenture authorized pursuant to this Article 8; provided, however,
that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental
indenture that adversely affects the Trustee’s rights, duties, liabilities or immunities. In executing any amendment or supplemental
indenture, the Trustee will receive, and (subject to Sections 10.01 and 10.02) will be fully protected in conclusively
relying on, an Officer’s Certificate and an Opinion of Counsel stating that (A) the execution and delivery of such amendment
or supplemental indenture is authorized or permitted by the Indenture; and (B) in the case of the Opinion of Counsel, such
amendment or supplemental indenture is valid, binding and enforceable against the Company in accordance with its terms.

 

Article 9.       Satisfaction
and Discharge

 

Section 9.01.       Termination
of Company’s Obligations.

 

The Indenture will
be discharged, and will cease to be of further effect as to all Notes issued under the Indenture, when:

 

(A)            all
Notes then outstanding (other than Notes replaced pursuant to Section 2.12) have (i) been delivered to the Trustee
for cancellation; or (ii) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the
Maturity Date, upon conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed;

 

(B)            the
Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with respect to Conversion
Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered
to the Holders, cash (or, with respect to Notes to be converted, Conversion Consideration) sufficient to satisfy all amounts or
other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.12);

 

(C)            the
Company has paid all other amounts payable by it under the Indenture with respect to the Notes; and

 

(D)            the
Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions
precedent to the discharge of the Indenture with respect to the Notes have been satisfied;

 

provided, however, that Article 10
and Section 11.01 will survive such discharge and, until no Notes remain outstanding, Section 2.14 and
the obligations of the Trustee, the Paying Agent and the Conversion Agent with respect to money or other property deposited with
them will survive such discharge.

 

At the Company’s
request, the Trustee will acknowledge the satisfaction and discharge of the Indenture with respect to the Notes.

 

For the avoidance of
doubt, the Notes will not be defeasible.

 

    	 	- 69 -	 

     

    

 

Section 9.02.       Repayment
to Company.

 

Subject to applicable
unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the Company if there exists
(and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held
by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on which such payment
or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further
liability to any Holder with respect to such cash, Conversion Consideration or other property, and Holders entitled to the payment
or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor
of the Company.

 

Section 9.03.       Reinstatement.

 

If the Trustee, the
Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to Section 9.01
because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or
otherwise prohibits such application, then the discharge of the Indenture pursuant to Section 9.01 will be rescinded;
provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to
the Holders thereof, then the Company will be subrogated to the rights of such Holders to receive such cash or other property from
the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable.

 

Article 10.       Trustee

 

Section 10.01.       Duties
of the Trustee.

 

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

 

(B)            Except
during the continuance of an Event of Default:

 

(i)            the
duties of the Trustee will be determined solely by the express provisions of the Indenture, and the Trustee need perform only those
duties that are specifically set forth in the Indenture and no others (including permissive rights), and no implied covenants or
obligations will be read into the Indenture against the Trustee; and

 

(ii)           in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel that are provided to the Trustee and
conform to the requirements of the Indenture. However, the Trustee will examine the certificates and opinions to determine whether
or not they conform as to form to the requirements of the Indenture (but need not confirm or investigate the accuracy of any mathematical
calculations or other facts stated therein).

 

    	 	- 70 -	 

     

    

 

(C)           The
Trustee may not be relieved from liabilities for its negligence or willful misconduct, except that:

 

(i)            this
paragraph will not limit the effect of Section 10.01(B);

 

(ii)           the
Trustee will 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;

 

(iii)          the
Trustee will 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 7.06; and

 

(iv)          no
provision of the Indenture will require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers.

 

(D)           Each
provision of the Indenture that in any way relates to the Trustee is subject to paragraphs (A), (B) and (C) of
this Section 10.01, regardless of whether such provision so expressly provides.

 

(E)           The
Trustee will not be liable for interest on any money received by it, except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds, except to the extent required by law.

 

Section 10.02.       Rights
of the Trustee.

 

(A)            The
Trustee may conclusively rely on any document that it believes to be genuine and signed or presented by the proper Person, and
the Trustee need not investigate any fact or matter stated in such document, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee determines to make such further
inquiry or investigation, it will be entitled to examine the books, records and premises of the Company, personally or by agent
or attorney at the sole cost of the Company and will incur no liability or additional liability of any kind by reason of such inquiry
or investigation (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

 

(B)            Before
the Trustee acts or refrains from acting, it may require an Officer’s Certificate, an Opinion of Counsel or both. The Trustee
will not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion
of Counsel. The Trustee may consult with counsel; and the written or verbal advice of such counsel, or any Opinion of Counsel,
will constitute full and complete authorization of the Trustee to take or omit to take any action in good faith in reliance thereon
without liability.

 

(C)            The
Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any such agent
appointed with due care.

 

(D)           The
Trustee will not be liable for any action it takes or omits to take in good faith and that it believes to be authorized or within
the rights or powers vested in it by the Indenture.

 

    	 	- 71 -	 

     

    

 

(E)           Unless
otherwise specifically provided in the Indenture, any demand, request, direction or notice from the Company will be sufficient
if signed by an Officer of the Company.

 

(F)          The
Trustee need not exercise any rights or powers vested in it by the Indenture at the request or direction of any Holder unless such
Holder has offered the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense that it
may incur in complying with such request or direction.

 

(G)          The
Trustee will not be responsible or liable for any punitive, special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

 

(H)          The
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,
are extended to, and will be enforceable by, the Trustee in each of its capacities hereunder and each Note Agent employed to act
hereunder.

 

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

 

(J)           Under
no circumstances will the Trustee be liable in its individual capacity for the obligations evidenced by the Notes.

 

(K)          The
Trustee will have no obligation to pursue any action that is not in accordance with applicable law.

 

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

 

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

 

(N)          The
Trustee will not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a Default is sent to the Trustee at the Corporate
Trust Office of the Trustee, and such notice references the Notes.

 

Section 10.03.       Individual
Rights of the Trustee.

 

The Trustee, in its
individual or any other capacity, may become the owner or pledgee of any Note and may otherwise deal with the Company or any of
its Affiliates with the same rights that it would have if it were not Trustee; provided, however, that if the Trustee
acquires a “conflicting interest” (within the meaning of Section 310(b) of the Trust Indenture Act), then
it must eliminate such conflict within ninety (90) days or resign as Trustee. Each Note Agent will have that same rights and duties
as the trustee under this Section 10.03.

 

    	 	- 72 -	 

     

    

 

Section 10.04.       Trustee’s
Disclaimer.

 

The Trustee will not
be (A) responsible for, and makes no representation as to, the validity, adequacy or enforceability of the Indenture or the
Notes; (B) accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon
the Company’s direction under any provision of the Indenture; (C) responsible for the use or application of any money
received by any Paying Agent other than the Trustee; (D) responsible for any statement or recital in the Indenture, the Notes
or any other document relating to the sale of the Notes or the Indenture, other than the Trustee’s certificate of authentication;
and (E) liable in its individual capacity for the obligations evidenced by the Notes.

 

Section 10.05.       Notice
of Defaults.

 

If a Default or an
Event of Default occurs with respect to the Notes and is continuing and is actually known to the Trustee, then the Trustee will
send Holders a notice of such Default or Event of Default within ninety (90) days after it occurs or, if it is not known to the
Trustee at such time, promptly (and in any event within ten (10) business days) after it becomes known to a Responsible Officer
of the trustee; provided, however, that, except in the case of a Default or Event of Default in the payment of the
principal of, or interest on, any Note, the Trustee may withhold such notice if and for so long as a Responsible Officer if the
Trustee in good faith determines that withholding such notice is in the interests of the Holders.

 

Section 10.06.       Compensation
and Indemnity.

 

(A)            The
Company will, from time to time, pay the Trustee (acting in any capacity hereunder) compensation as agreed to by the Company and
the Trustee in writing for its acceptance of the Indenture and services under the Indenture. The Trustee’s compensation will
not be limited by any law on compensation of a trustee of an express trust. In addition to the compensation for the Trustee’s
services, the Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses
incurred or made by it under the Indenture, including the reasonable compensation, disbursements and expenses of the Trustee’s
agents and counsel.

 

(B)            The
Company will indemnify the Trustee in any capacity under the Indenture and any other document or transaction entered into in connection
herewith and their agents and any authentication agent for and to hold it harmless against any and all costs, damages, losses,
liabilities, fees or expenses incurred on the part of the Trustee, its officers, directors, agents or employees, and arising out
of or in connection with the acceptance or administration of its duties under the Indenture, including the costs and expenses of
enforcing the Indenture against the Company (including reasonable counsel fees and expenses and court costs in connection with
the enforcement of this Section 10.06) and 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 or duties under the
Indenture, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct,
as finally adjudicated by a court of competent jurisdiction. The Trustee will promptly notify the Company of any claim for which
it may seek indemnity, but the Trustee’s failure to so notify the Company will not relieve the Company of its obligations
under this Section 10.06(B). The Company will defend such claim, and the Trustee will cooperate in such defense. The
Trustee may retain separate counsel, and the Company will pay the reasonable fees and expenses of such counsel.

 

    	 	- 73 -	 

     

    

 

(C)           The
obligations of the Company under this Section 10.06 will survive the resignation or removal of the Trustee and the
satisfaction and discharge of the Indenture.

 

(D)           To
secure the Company’s payment obligations in this Section 10.06, the Trustee will have a lien prior to the Notes
on all money or property held or collected by the Trustee, except that held in trust to pay principal of, or interest on, particular
Notes, which lien will survive the discharge of the Indenture.

 

(E)            If
the Trustee incurs expenses or renders services after an Event of Default pursuant to clause (ix) or (x) of
Section 7.01(A) occurs, then such expenses and the compensation for such services (including the fees and expenses
of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

 

Section 10.07.       Replacement
of the Trustee.

 

(A)            A
resignation or removal of the Trustee, and the appointment of a successor Trustee, will become effective only upon such successor
Trustee’s acceptance of appointment as provided in this Section 10.07.

 

(B)            The
Trustee may resign at any time and be discharged from the trust created by the Indenture by so notifying the Company. The Holders
of a majority in aggregate principal amount of the Notes then outstanding may remove the Trustee upon 30 days written notice to
the Trustee and the Company. The Company may remove the Trustee if:

 

(i)            the
Trustee fails to comply with Section 10.09;

 

(ii)            the
Trustee is adjudged to be bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy
Law;

If the Trustee is then
acting as the Depositary’s custodian for the Notes, then, at the reasonable request of the Company to the Trustee, the Trustee
will cause any notice prepared by the Company to be sent to any Holder(s) pursuant to the Depositary Procedures, provided
such request is evidenced in a Company Order delivered, together with the text of such notice, to the Trustee at least two (2) Business
Days before the date such notice is to be so sent. For the avoidance of doubt, such Company Order need not be accompanied by an
Officer’s Certificate or Opinion of Counsel. The Trustee will not have any liability relating to the contents of any notice
that it sends to any Holder pursuant to any such Company Order.

 

If a notice or communication
is mailed or sent in the manner provided above within the time prescribed, it will be deemed to have been duly given, whether or
not the addressee receives it.

 

Notwithstanding anything
to the contrary in the Indenture or the Notes, whenever any provision of the Indenture requires a party to send notice to another
party, no such notice need be sent if the sending party and the recipient are the same Person acting in different capacities.

or document by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set

such court. Each of the Company, the Trustee and each Holder (by its acceptance of any Note) irrevocably and unconditionally waives

help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies
each person or legal entity that establishes a relationship or opens an account with the Trustee. The Company agrees to provide
the Trustee with such information as it may request to enable the Trustee to comply with the U.S.A. PATRIOT Act.

 

Section 11.12.       Calculations.

 

Except as otherwise
provided in the Indenture, the Company will be responsible for making all calculations called for under the Indenture or the Notes,
