heading “Bloomberg VWAP” on Bloomberg page “MARA <EQUITY> AQR” (or, if such page is not available, its

(50%) of all classes of common equity of the surviving, continuing or acquiring company or other transferee, as applicable, or the parent
thereof, in substantially the same proportions vis-à-vis each other as immediately before such transaction will be deemed not
to be a Fundamental Change pursuant to this clause (B);


 


(C)
the Company’s stockholders approve any plan or proposal for the liquidation or dissolution of the Company; or


 


(D)

listed on any of The New York Stock Exchange, The Nasdaq Capital Market, The Nasdaq Global Market or The Nasdaq Global Select Market
(or any of their respective successors), or that will be so listed when issued or exchanged in connection with such transaction or event,
and such transaction or event constitutes a Common Stock Change Event whose Reference Property consists of such consideration.


 


For
the purposes of this definition, (x) any transaction or event described in both clause (A) and in clause (B)(i) or (ii)
above (without regard to the proviso in clause (B)) will be deemed to occur solely pursuant to clause (B) above (subject
to such proviso); and (y) whether a Person is a “beneficial owner,” whether shares are “beneficially owned,”
and percentage beneficial ownership, will be determined in accordance with Rule 13d-3 under the Exchange Act.

“Last
Reported Sale Price” of the Common Stock for any Trading Day means the closing sale price per share (or, if no closing sale
price is reported, the average of the last bid price and the last ask price per share or, if more than one in either case, the average
of the average last bid prices and the average last ask prices per share) of Common Stock on such Trading Day as reported in composite
transactions for the principal U.S. national or regional securities exchange on which the Common Stock is then listed. If the Common
Stock is not listed on a U.S. national or regional securities exchange on such Trading Day, then the Last Reported Sale Price will be
the last quoted bid price per share of Common Stock on such Trading Day in the over-the-counter market as reported by OTC Markets Group

average of the mid-point of the last bid price and the last ask price per share of Common Stock on such Trading Day from a nationally

nor the Conversion Agent will have any duty to determine the Last Reported Sale Price.

the sending of a Redemption Notice will constitute a Make-Whole Fundamental Change only with respect to the Notes called (or deemed called
pursuant to Section 4.03(J)) 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:

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 a Fundamental
Change (other than an Exempted Fundamental Change), to, but excluding, the related Fundamental Change Repurchase Date); and


 




    	-6-

rule or usage or the Depositary. Each Note will be dated as of the date of its authentication.


 


Except
to the extent otherwise provided in a Company Order delivered to the Trustee in connection with the issuance and authentication thereof,
the Notes will be issued initially in the form of one or more Global Notes. Global Notes may be exchanged for Physical Notes, and Physical
Notes may be exchanged for Global Notes, only as provided in Section 2.10.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. A duly appointed authenticating agent
may authenticate Notes whenever the Trustee may do so under this Indenture, and a Note authenticated as provided in this Indenture by
such an agent will be deemed, for purposes of this Indenture, to be authenticated by the Trustee. Each duly appointed authenticating

agent was validly appointed to undertake.

plus any Additional Interest and Special Interest that may accrue pursuant to Sections 3.04 and 7.03, respectively. 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. Stated Interest, and, if applicable, Additional Interest and Special Interest, on the Notes will be computed on
the basis of a 360-day year comprised of twelve 30-day months.


 


(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 this 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.


 




    	-16-



     


    

 


(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 this Indenture
is not a Business Day, then, notwithstanding anything to the contrary in this 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 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.”

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 and will be entitled to receive compensation therefor in accordance
with this Indenture and any other agreement between the Trustee and the Company. For the avoidance of doubt, the Company or any of its
Subsidiaries may act as Registrar, Paying Agent or Conversion Agent without prior notice to Holders.


 


(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.


 


(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 and co-Conversion Agents, each of whom will be deemed to be a Registrar, Paying Agent or
Conversion Agent, as applicable, under this 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
this Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions
of this Indenture that relate to such Note Agent.


 




    	-17-



     


    

 


(D)
Initial Appointments. The Company appoints the Trustee as (and the Trustee’s office in the continental United States as
the location of) the initial Paying Agent, the initial Registrar and the initial Conversion Agent.


 


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 this 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 clause (viii) or (ix) 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.


 


Section
2.09. Legends.


 


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


 


(B)
Non-Affiliate Legend. Each Note will bear the Non-Affiliate Legend.


 


(C)
Restricted Note Legend. Subject to Section 2.12,


 


(i)
each Note that is a Transfer-Restricted Security will bear the Restricted Note Legend; and


 




    	-18-



     


    

 


(ii)
if a Note is issued in exchange for, in substitution of, or to effect a partial conversion of, another Note (such other Note being referred
to as the “old Note” for purposes of this Section 2.09(C)(ii)), including pursuant to Section 2.10(B), 2.10(C),
2.11 or 2.13, then such Note will bear the Restricted Note Legend if such old Note bore the Restricted Note Legend at the
time of such exchange or substitution, or on the related Conversion Date with respect to such conversion, as applicable; provided,
however, that such Note need not bear the Restricted Note Legend if such Note does not constitute a Transfer-Restricted Security
immediately after such exchange or substitution, or as of such Conversion Date, as applicable.


 


(D)
Other Legends. A Note may bear any other legend or text, not inconsistent with this 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.


 


(E)
Acknowledgment 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 acknowledgment of, and agreement to comply with, the restrictions set forth in such legend.


 


(F)
Restricted Stock Legend.


 


(i)
Each Conversion Share will bear the Restricted Stock Legend if the Note upon the conversion of which such Conversion Share was issued
was (or would have been had it not been converted) a Transfer-Restricted Security at the time such Conversion Share was issued; provided,
however, that such Conversion Share need not bear the Restricted Stock Legend if the Company determines, in its reasonable discretion,
that such Conversion Share need not bear the Restricted Stock Legend.


 


(ii)
Notwithstanding anything to the contrary in this Section 2.09(F), a Conversion Share need not bear a Restricted Stock Legend if
such Conversion Share is issued in an uncertificated form that does not permit affixing legends thereto, provided the Company
takes measures (including the assignment thereto of a “restricted” CUSIP number) that it reasonably deems appropriate to
enforce the transfer restrictions referred to in the Restricted Stock Legend.


 


Section
2.10. Transfers and Exchanges; Certain Transfer Restrictions.


 


(A)
Provisions Applicable to All Transfers and Exchanges.


 


(i)
Generally. 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 of Physical Notes in the Register.


 


(ii)
Transferred and Exchanged Notes Remain Valid Obligations of the Company. 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 this Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the
same benefits under this Indenture, as such old Note or portion thereof, as applicable.


 




    	-19-



     


    

 


(iii)
No Services Charge; Transfer Taxes. 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 Section 2.11, 2.17 or 8.05 not involving any transfer.


 


(iv)
Transfers and Exchanges Must Be in Authorized Denominations. Notwithstanding anything to the contrary in this 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)
Trustee’s Disclaimer. The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with
any transfer restrictions imposed under this Indenture or applicable law with respect to any Security, other than to require the delivery
of such certificates or other documentation or evidence as expressly required by this Indenture and to examine the same to determine
substantial compliance as to form with the requirements of this Indenture.


 


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


 


(vii)
Settlement of Transfers and Exchanges. Upon satisfaction of the requirements of this 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.


 


(viii)
Interpretation. For the avoidance of doubt, and subject to the terms of this Indenture, as used in this Section 2.10, an
“exchange” of a Global Note or a Physical Note includes (x) an exchange effected for the sole purpose of removing any Restricted
Note Legend affixed to such Global Note or Physical Note; and (y) if such Global Note or Physical Note is identified by a “restricted”
CUSIP number, an exchange effected for the sole purpose of causing such Global Note or Physical Note to be identified by an “unrestricted”
CUSIP number.


 


(ix)
Neither the Trustee nor any Note Agent will have any responsibility for any action taken or not taken by the Depositary.


 


(B)
Transfers and Exchanges of Global Notes.


 


(i)
Certain Restrictions. 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:


 




    	-20-



     


    

 


(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)
Effecting Transfers and Exchanges. Upon satisfaction of the requirements of this 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 2.15);


 


(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;


 


(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


 


(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 (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount
of such Global Note to be so exchanged; (y) are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant
to customary procedures); and (z) bear each legend, if any, required by Section 2.09.


 




    	-21-



     


    

 


(iii)
Compliance with Depositary Procedures. 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)
Requirements for Transfers and Exchanges. 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:


 


(1)
surrender such Physical Note to be transferred or exchanged to the office of the Registrar, together with any endorsements or transfer
instruments reasonably required by the Company, the Trustee or the Registrar; and


 


(2)
deliver such certificates, documentation or evidence as may be required pursuant to Section 2.10(D).


 


(ii)
Effecting Transfers and Exchanges. Upon the satisfaction of the requirements of this 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 2.15;


 


(2)
if such old Physical Note is to be so 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 so transferred
or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by Section 2.09;


 




    	-22-



     


    

 


(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), 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)
Requirement to Deliver Documentation and Other Evidence. If a Holder of any Note that is identified by a “restricted”
CUSIP number or that bears a Restricted Note Legend or is a Transfer-Restricted Security requests to:


 


(i)
cause such Note to be identified by an “unrestricted” CUSIP number;


 


(ii)
remove such Restricted Note Legend; or


 


(iii)
register the transfer of such Note to the name of another Person,


 


then
the Company, the Trustee and the Registrar may refuse to effect such identification, removal or transfer, as applicable, unless there
is delivered to the Company, the Trustee and the Registrar such certificates or other documentation or evidence as the Company, the Trustee
and the Registrar may reasonably require in order for the Company to determine that such identification, removal or transfer, as applicable,
complies with the Securities Act and other applicable securities laws; provided, however, that no such certificates, documentation
or evidence need be so delivered on and after the Free Trade Date with respect to such Note unless the Company determines, in its reasonable
discretion, that such Note is not eligible to be offered, sold or otherwise transferred pursuant to Rule 144 or otherwise without any
requirements as to volume, manner of sale, availability of current public information or notice under the Securities Act.


 




    	-23-



     


    

 


(E)
Transfers of Notes Subject to Redemption, Repurchase or Conversion. Notwithstanding anything to the contrary in this 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 any portion of such
Note is not subject to Redemption or 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, Redemptions 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 or Redemption, then, as soon as
reasonably practicable after such Physical Note is surrendered for such conversion, Redemption 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,
redeemed 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, redeemed or repurchased, as applicable, which Physical Note will be converted,
redeemed or repurchased, as applicable, pursuant to the terms of this 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, Redemption
or repurchase, as applicable, is deemed to cease to be outstanding pursuant to Section 2.18.


 


(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
2.18 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 2.15; and (2) in the case of a partial conversion, Redemption 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, redeemed or repurchased; (y) are registered in the name of such Holder; and (z)
bear each legend, if any, required by Section 2.09.


 




    	-24-



     


    

 


(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 subject to Redemption, then, promptly after the time such Note (or such portion) is deemed
to cease to be outstanding pursuant to Section 2.18, 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 2.15).


 


Section
2.12. Removal of Transfer Restrictions.


 


Without
limiting the generality of any other provision of this Indenture (including Section 3.04), the Restricted Note Legend affixed
to any Note will be deemed, pursuant to this Section 2.12 and the footnote to such Restricted Note Legend, to be removed therefrom
upon the Company’s delivery to the Trustee of notice, signed on behalf of the Company by one (1) of its Officers, to such effect
(and, for the avoidance of doubt, such notice need not be accompanied by an Officer’s Certificate or an Opinion of Counsel in order
to be effective to cause such Restricted Note Legend to be deemed to be removed from such Note unless a new Note is to be authenticated
in connection therewith). If such Note bears a “restricted” CUSIP or ISIN number at the time of such delivery, then, upon
such delivery, such Note will be deemed, pursuant to this Section 2.12 and the footnotes to the CUSIP and ISIN numbers set forth
on the face of the certificate representing such Note, to thereafter bear the “unrestricted” CUSIP and ISIN numbers identified
in such footnotes; provided, however, that if such Note is a Global Note and the Depositary thereof requires a mandatory
exchange or other procedure to cause such Global Note to be identified by “unrestricted” CUSIP and ISIN numbers in the facilities
of such Depositary, then (i) the Company will effect such exchange or procedure as soon as reasonably practicable; and (ii) for purposes
of Section 3.04 and the definition of Freely Tradable, such Global Note will not be deemed to be identified by “unrestricted”
CUSIP and ISIN numbers until such time as such exchange or procedure is effected.


 


Section
2.13. 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 may
require the Holder thereof to provide such security or indemnity that is satisfactory to the Company to protect the Company and the Trustee
and that is reasonably satisfactory to the Trustee to protect from any loss that any of them may suffer if such Note is replaced.


 




    	-25-



     


    

 


Every
replacement Note issued pursuant to this Section 2.13 will be an additional obligation of the Company and will be entitled to
all of the benefits of this Indenture equally and ratably with all other Notes issued under this Indenture.


 


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


 


Only
the Holder of a Note will have rights under this Indenture as the owner of such Note. Without limiting the generality of the foregoing,
Depositary Participants will have no rights as such under this 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 this 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
2.15. Cancellation.


 


Without
limiting the generality of Section 3.07, 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
2.16. Notes Held by the Company or its Affiliates.


 


Without
limiting the generality of Sections 3.07 and 2.18, in determining whether the Holders of the required aggregate principal amount
of Notes have concurred in any direction, waiver or consent or other action under this Indenture, 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 or other action under this Indenture, only Notes that a Responsible
Officer of the Trustee knows are so owned will be so disregarded.


 


Section
2.17. 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 this Indenture as definitive Notes.


 




    	-26-



     


    

 


Section
2.18. 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 2.15; (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 (including
upon conversion) in accordance with this Indenture; (iv) deemed to cease to be outstanding to the extent provided in, and subject to,
clause (B), (C) or (D) of this Section 2.18; or (v) deemed not to be outstanding pursuant to Section 2.16.


 


(B)
Replaced Notes. If a Note is replaced pursuant to Section 2.13, 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, 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 this 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(B) 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) or Section 5.08.

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.

(B)
Trustee’s Disclaimer. The Trustee will not be responsible for determining whether the Company has filed any material via
the EDGAR system (or such successor) or for the timeliness of its content. The sending or filing of reports, information and documents
pursuant to Section 3.02(A) is for informational purposes only and the information and the Trustee’s receipt of the foregoing

on a continuing basis or otherwise, the Company’s compliance with its covenants under this Indenture or with respect to any reports
or other documents filed with the SEC via the EDGAR system (or any successor thereto) or any other website, or to participate in any
conference calls.


 


Section
3.03. Rule 144A Information.


 


If
the Company is not subject to Section 13 or 15(d) of the Exchange Act at any time when any Notes or shares of Common Stock issuable upon
conversion of the Notes are outstanding and constitute “restricted securities” (as defined in Rule 144), then the Company
(or its successor) will promptly provide, to the Trustee and, upon written request, to any Holder, beneficial owner or prospective purchaser
of such Notes or shares, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate
the resale of such Notes or shares pursuant to Rule 144A. The Company (or its successor) will take such further action as any Holder

Issue Date of any Note,


 


(1)
the Company fails to timely file any report (other than Form 8-K reports) that the Company is required to file with the SEC pursuant
to Section 13 or 15(d) of the Exchange Act (after giving effect to all applicable grace periods thereunder); or

Freely Tradable.


 


(ii)
In addition, Additional Interest will accrue on a Note on each day on which such Note is not Freely Tradable on or after the De-Legending
Deadline Date for such Note.


 




    	-29-



     


    

 


(B)
Amount and Payment of Additional Interest. Any Additional Interest that accrues on a Note pursuant to Section 3.04(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 Additional Interest accrues
and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof; provided, however,
that in no event will Additional Interest, together with any Special Interest, accrue on any day on a Note at a combined rate per annum
that exceeds one half of one percent (0.50%). For the avoidance of doubt, any Additional Interest that accrues on a Note will be in addition
to the Stated Interest that accrues on such Note and, subject to the proviso of the immediately preceding sentence, in addition to any
Special Interest that accrues on such Note.


 


(C)
Notice of Accrual of Additional Interest; Trustee’s Disclaimer. The Company will send written notice to the Holder of each
Note, and to the Trustee, of the commencement and termination of any period in which Additional Interest accrues on such Note. In addition,
if Additional Interest accrues on any Note, then, no later than five (5) Business Days before each date on which such Additional 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 Additional Interest on such Note on such date of payment; and (ii) the amount of such Additional Interest that is
payable on such date of payment. The Trustee will have no duty to determine whether any Additional Interest is payable or the amount
thereof.


 


(D)
Exclusive Remedy. The accrual of Additional Interest will be the exclusive remedy available to Holders for the failure of their
Notes to become Freely Tradable.


 


Section
3.05. Compliance and Default Certificates.


 


(A)
Annual Compliance Certificate. Within ninety (90) days after December 31, 2021 and each fiscal year of the Company ending thereafter,

of the activities of the Company and its Subsidiaries during such fiscal year with a view towards determining whether any Default or
Event of Default has occurred; and (ii) whether, to such signatory’s knowledge, a Default or Event of Default has occurred or is
continuing (and, if so, describing all such Defaults or Events of Default and what action the Company is taking or proposes to take with
respect thereto).


 


(B)
Default Certificate. If a Default or Event of Default occurs, then the Company will promptly deliver an Officer’s Certificate
to the Trustee describing the same and what action the Company is taking or proposes to take with respect thereto.


 


Section
3.06. Stay, 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 this 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 this Indenture,
but will suffer and permit the execution of every such power as though no such law has been enacted.

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 (including as a result
of the payment of the related Fundamental Change Repurchase Price, and any related interest pursuant to the proviso to the first sentence
of Section 4.02(D), 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).


 


(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 as 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.


 




    	-31-



     


    

 


(E)
Fundamental Change Notice. On or before the twentieth (20th) calendar day after the occurrence of a Fundamental Change, the Company
will send to each Holder in writing, with a copy to the Trustee, the Paying Agent and the Conversion Agent a notice of such Fundamental
Change (a “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;


 


(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 the first sentence of Section 4.02(D));


 


(vi)
the name and 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 for the Holder thereof to be entitled to receive the Fundamental Change Repurchase Price;


 




    	-32-



     


    

 


(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 this 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 (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.


 


(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)).


 




    	-33-



     


    

 


(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 (or, if applicable with respect to
any Global Note, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial
interest in such Note in accordance with the Depositary Procedures).


 


(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 the first sentence of Section 4.02(D) on any Note to be repurchased
pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is delivered or
such Depositary Procedures are complied with pursuant to the first sentence of this Section 4.02(G).


 


(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 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 the same manner,
at the same time and otherwise in compliance with the requirements for an offer made by the Company as provided in this Section
4.02 that would have satisfied the requirements of this Section 4.02 if conducted directly by the Company.


 




    	-34-



     


    

 


(I)
No Requirement to Conduct an Offer to Repurchase Notes if the Fundamental Change Results in the Notes Becoming Convertible into an
Amount of Cash Exceeding the Fundamental Change Repurchase Price. Notwithstanding anything to the contrary in this Section 4.02,
the Company will not be required to send a Fundamental Change Notice pursuant to Section 4.02(E), or offer to repurchase or repurchase
any Notes pursuant to this Section 4.02, in connection with a Fundamental Change occurring pursuant to clause (B)(ii) (or
pursuant to clause (A) that also constitutes a Fundamental Change occurring pursuant to clause (B)(ii)) of the definition
thereof, if (i) such Fundamental Change constitutes a Common Stock Change Event whose Reference Property consists entirely of cash in
U.S. dollars; (ii) immediately after such Fundamental Change, the Notes become convertible, pursuant to Section 5.09(A) and, if
applicable, Section 5.07, into consideration that consists solely of U.S. dollars in an amount per $1,000 aggregate principal
amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per $1,000 aggregate principal amount of Notes (calculated
assuming that the same includes the maximum amount of accrued interest payable as part of the related Fundamental Change Repurchase Price);
and (iii) the Company timely sends the notice relating to such Fundamental Change required pursuant to Section 5.01(C)(i)(3)(b).
For the avoidance of doubt, the maximum amount of accrued interest referred to in clause (I)(ii) above will be determined (x)
by assuming that the Fundamental Change Repurchase Date occurs on the latest possible date permitted for the applicable Fundamental Change
pursuant to Section 4.02(E) and Section 4.02(C); and (y) without regard to the proviso to the first sentence of Section
4.02(D).


 


(J)
Compliance with Applicable Securities Laws. To the extent applicable, the Company will comply, in all material respects, with
all U.S. 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 this Indenture; provided, however, that, to the extent that the Company’s
obligations pursuant to this Section 4.02 conflict with any law or regulation that is applicable to the Company and enacted after
the Issue Date, the Company’s compliance with such law or regulation will not be considered to be a Default of such obligations;
rather, the Company will be deemed to be in compliance with such obligations if the Company complies with its obligation to effect Repurchases
Upon a Fundamental Change in accordance with this Section 4.02, modified as necessary by the Company in good faith to permit compliance
with such law or regulation.


 


(K)
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.


 




    	-35-



     


    

 


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


 


(A)

2024.


 


(B)
Right to Redeem the Notes on or After December 6, 2024. Subject to the terms of this Section 4.03, the Company has the
right, at its election, to redeem all, or any portion (subject to the Partial Redemption Limitation set forth in Section 4.03)
in an Authorized Denomination, of the Notes, at any time, and from time to time, on a Redemption Date on or after December 6, 2024 and
on or before the twenty first (21st) 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 that Note pursuant to clause (B) of the definition thereof.


 


(C)
Partial Redemption Limitation. If the Company elects to redeem fewer than all of the outstanding Notes, at least one hundred million
dollars ($100,000,000) aggregate principal amount of Notes must be outstanding and not subject to Redemption as of the Redemption Notice
Date for such Redemption (such requirement, the “Partial Redemption Limitation”).


 


(D)
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 (including a rescission as a result of the payment of the related Redemption
Price, and any related interest pursuant to the proviso to Section 4.03(E), 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 (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 interests in such
Notes in accordance with the Depositary Procedures).


 


(E)
Redemption Date. The Redemption Date for any Redemption will be a Business Day of the Company’s choosing that is no more
than forty five (45), nor less than twenty five (25), Scheduled Trading Days after the Redemption Notice Date for such Redemption (it
being understood, for the avoidance of doubt, that such Redemption Notice Date will be at least four (4) Scheduled Trading Days before
the first VWAP Trading Day of the Observation Period relating to such Redemption date pursuant to clause (B) of the definition
of Observation Period); provided, however, that if, in accordance with Section 5.03(A)(i)(3), the Company has elected
to settle all conversions for Notes called for Redemption with a Conversion Date that occurs during the related Redemption Conversion
Period by Physical Settlement, then the Company may instead elect to choose a Redemption Date that is a Business Day no more than sixty
(60), nor less than thirty (30), calendar days after such Redemption Notice Date.


 




    	-36-



     


    

 


(F)
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 as 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.


 


(G)
Redemption Notice. To call any Notes for Redemption, the Company must send to each Holder of such Notes, the Trustee, the Conversion
Agent and the Paying Agent a written notice of such Redemption (a “Redemption Notice”).


 


Such
Redemption Notice must state:


 


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


 


(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 second (2nd) Scheduled Trading 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 during the related Redemption Conversion
Period; and


 




    	-37-



     


    

 


(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, the Conversion Agent and
the Paying Agent. At the Company’s written request, the Trustee will give the Redemption Notice in the Company’s name and
at its expense, provided that the Company delivers to the Trustee, at least five Business Days in the case of Physical Notes and five
calendar days in the case of Global Notes prior to the Redemption Notice Date (unless the Trustee agrees to a shorter period), an Officer’s
Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in
this Section 4.03(G).


 


(H)
Selection, Conversion and Transfer 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.


 


(I)
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 (or portion thereof) 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.


 


(J)
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 twenty second (22nd) Scheduled Trading Day (or, if, in accordance with Section 5.03(A)(i)(3),
the Company has elected to settle all conversions of Notes with a Conversion Date that occurs during the related Redemption Conversion
Period, 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 during the related Redemption Conversion Period (subject to extension of the
Redemption Conversion Period pursuant to Section 4.03(G)(v)), 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. The Trustee will have no obligation
to make any determination in connection with the foregoing.

Article
5. Conversion


 


Section
5.01. Right to Convert.


 


(A)
Generally. Subject to the provisions of this Article 5, each Holder may, at its option, convert such Holder’s Notes
into Conversion Consideration.


 


(B)
Conversions in Part. Subject to the terms of this 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 Sale Price Condition. Before the Close of Business on the Business Day immediately before September
1, 2026, a Holder may convert its Notes during any calendar quarter (and only during such calendar quarter) commencing after the calendar
quarter ending on March 31, 2022, 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.


 


(2)
Conversion upon Satisfaction of Note Trading Price Condition. Before the Close of Business on the Business Day immediately before
September 1, 2026, a Holder may convert its Notes during the five (5) consecutive Business Days immediately after any ten (10) consecutive
Trading Day period (such ten (10) 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 this Indenture as the “Trading Price Condition.”


 


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. 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 notify the Holders, the Trustee and the Conversion Agent of the
same.

(3)
Conversion upon Specified Corporate Events.


 


(a)
Certain Distributions. If, before the Close of Business on the Business Day immediately before September 1, 2026, 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 sixty (60) calendar days
after the date such distribution is announced, 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


 


(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 Company in good faith, 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 twenty five (25) Scheduled Trading Days before the Ex-Dividend Date for such distribution (or, if later
in the case of any such separation of rights issued pursuant to a stockholder rights plan or the occurrence of any such triggering event
under a stockholder rights plan, no later than the Business Day after the Company becomes aware that such separation or triggering event
has occurred or will occur); 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; provided, however, that the Notes will not become convertible pursuant to clause (y)
above (but the Company will be required to send notice of such distribution pursuant to clause (x) above) on account of such distribution
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,
in such distribution 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 record date for such distribution; and (ii) the aggregate principal
amount (expressed in thousands) of Notes held by such Holder on such date; provided, further, that if the Company is then
otherwise permitted to settle conversions of Notes by Physical Settlement (and, for the avoidance of doubt, the Company has not elected
another Settlement Method to apply, including pursuant to Section 5.03(A)(i)(1)), then the Company may instead elect to provide
such notice at least ten (10) Scheduled Trading Days before such Ex-Dividend Date, in which case (x) the Company must settle all conversions
of Notes with a Conversion Date occurring on or after the date the Company provides such notice and on or before the Business Day immediately
before the Ex-Dividend Date for such distribution (or any earlier announcement by the Company that such distribution will not take place)
by Physical Settlement; and (y) such notice must state that all such conversions will be settled by Physical Settlement.


 




    	-40-



     


    

 


(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 (other than a merger or other business combination
transaction that is effected solely to change the Company’s jurisdiction of incorporation and that does not constitute a Fundamental
Change or a Make-Whole Fundamental Change), 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 (other than an Exempted Fundamental Change), to, but excluding, the related
Fundamental Change Repurchase Date); provided, however, that if the Company does not provide the notice referred to in
the immediately following sentence by the Business Day after 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, the Business Day after such effective
date to, but excluding, the date the Company provides such notice. No later than the Business Day after such effective date, the Company
will send written 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.


 


(4)
Conversion upon Redemption. If the Company calls any Note for Redemption before the Close of Business on the Business Day immediately
before September 1, 2026, then the Holder of such Note may convert such Note at any time during the related Redemption Conversion Period.


 


(5)
Conversions During Free Convertibility Period. On or after September 1, 2026, a Holder may convert its Notes at any time until
the Close of Business on the second (2nd) Scheduled Trading Day immediately before the Maturity Date regardless of the conditions set
forth in sub-paragraphs (1), (2), (3) or (4) of this Section 5.01(C)(i).


 


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).


 


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


 


(1)
Notes may be surrendered for conversion during a period where the Notes are convertible pursuant to Section 5.01(C) only after
the Open of Business and before the Close of Business on 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 second (2nd) Scheduled Trading 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 this Indenture; and


 




    	-41-



     


    

 


(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
this Indenture (or a third party fails to make such payment in lieu of the Company in accordance with Section 4.02(H)).


 


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) 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(B) or 5.02(D), upon such conversion) 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.


 




    	-42-



     


    

 


(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 Conversion Agent,
at the time of such surrender, an amount of cash equal to the amount of such interest referred to in clause (i) above; provided,
however, that the Holder surrendering such Note for conversion need not deliver such cash (w) if such Note is called (or deemed,
pursuant to Section 4.03(J), to be called) for Redemption and such Conversion Date occurs during the related Redemption Conversion
Period; (x) if such Conversion Date occurs after the Regular Record Date immediately before the Maturity Date; (y) 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 (z) to the extent of any overdue interest or interest that has accrued on any overdue interest. 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. 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).


 


(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 or delivery 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 Conversion Agent 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 (and, in any event, no later
than the date the Conversion Agent receives such Note or notice) notify the Company and the Trustee of such occurrence, together with
any other information reasonably requested by the Company, and will cooperate with the Company to determine the Conversion Date for such
Note.


 


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(B)(i)(1) (a “Physical Settlement”); (y) solely cash as provided in Section
5.03(B)(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(B)(i)(3) (a “Combination Settlement”).


 




    	-43-



     


    

 


(i)
The Company’s Right to Elect Settlement Method. The Company will have the right to elect the Settlement Method applicable
to any conversion of a Note; provided, however, that:


 


(1)
subject to clause (3) below, all conversions of Notes with a Conversion Date that occurs on or after September 1, 2026 will be
settled using the same Settlement Method, and the Company will send written notice of such Settlement Method to Holders, the Trustee
and the Conversion Agent no later than the Open of Business on September 1, 2026;


 


(2)
subject to clause (3) below, if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion
Date occurs before September 1, 2026, 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;


 


(3)
if any Notes are called for Redemption, then (a) the Company will specify, in the related Redemption Notice sent pursuant to Section
4.03(G), the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs during the related
Redemption Conversion Period; and (b) if such Redemption Date occurs on or after September 1, 2026, then such Settlement Method must
be the same Settlement Method that, pursuant to clause (1) above, applies to all conversions of Notes with a Conversion Date that
occurs on or after September 1, 2026;


 


(4)
the Company will use the same Settlement Method for all conversions of Notes with the same Conversion Date (and, for the avoidance of
doubt, the Company will not be obligated to use the same Settlement Method with respect to conversions of Notes with different Conversion
Dates, except as provided in clause (1) or (3) above);


 


(5)
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); and


 


(6)
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


 


(7)
the Settlement Method will be subject to Sections 4.03(E), 5.09(A)(2), 5.01(C)(i)(3)(a) and 5.07(D).


 




    	-44-



     


    

 


(ii)
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 irrevocably (1) 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 (2) irrevocably eliminate any one or more (but not all) Settlement Methods (including eliminating or electing Combination Settlement
with a particular Specified Dollar Amount or a range of Specified Dollar Amounts) with respect to all conversions of Notes with a Conversion
Date that occurs on or after the date such notice is sent to Holders; provided that the Settlement Method so elected pursuant
to clause (1) above, or the Settlement Method(s) remaining after any elimination pursuant to clause (2) above, as applicable,
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(A)). Such notice, if sent, must set forth
the Settlement Method so elected, or the Settlement Method(s) so eliminated, as applicable, 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. Upon any such irrevocable election pursuant to clause (1) above, the Default Settlement Method will automatically be
deemed to be set to the Settlement Method so elected; and upon any such irrevocable election pursuant to clause (2) above, the
Company will, if needed, simultaneously change the Default Settlement Method to a Settlement Method that is consistent with such irrevocable
election. Notwithstanding anything to the contrary in the preceding sentences of this paragraph, no such change in the Default Settlement
Method or irrevocable election will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note
pursuant to this Section 5.03(A). For the avoidance of doubt, such an irrevocable election, if made, will be effective without
the need to amend this 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).


 


(B)
Conversion Consideration.


 


(i)
Generally. Subject to Sections 5.03(B)(ii), 5.03(B)(iii) and 5.09(A)(2), 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.


 




    	-45-



     


    




 


(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(B)(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 applicable 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.


 


(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, the Conversion Agent nor the Paying Agent will have any duty to make any such determination.


 


(C)
Delivery of the Conversion Consideration. Except as set forth in Sections 5.05(D), 5.07(D) and 5.09, 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.


 


(D)
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 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.


 




    	-46-



    	 



    

 


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, unreserved and not
outstanding 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. To the extent the Company delivers shares of Common Stock
held in its treasury in settlement of the conversion of any Notes, each reference in this Indenture or the Notes to the issuance of shares
of Common Stock in connection therewith will be deemed to include such delivery, mutatis mutandis.


 


(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 (except that any Conversion Share delivered by a designated financial institution pursuant to Section 5.08 need
not 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 use commercially reasonable efforts to 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 5.09 will apply), then
the Conversion Rate will be adjusted based on the following formula:


 











 




    	-47-



    	 



    

 


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 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.


 


If
any dividend or distribution of the type described in this Section 5.05(A)(i) is declared, but not so paid, then the Conversion
Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would then be in effect had such dividend or distribution not been declared.


 


(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 Sections 5.05(A)(iii)(1)
and 5.05(F) will apply) entitling such holders, for a period of not more than sixty (60) calendar days after the date such
distribution is announced, 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.


 




    	-48-



    	 



    

 


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, options 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.


 


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 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 Company in good faith.


 


(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);


 




    	-49-



    	 



    

 


(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, as to which Section 5.05(A)(v)
will apply; and


 


(z)
a distribution solely pursuant to a Common Stock Change Event, as to which Section 5.09 will apply,


 


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 Company in good faith), 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.


 




    	-50-



    	 



    

 


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 (x) a Common Stock Change Event, as to which Section 5.09 will apply; or (y) a tender offer
or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply), 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:


 





 


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, the Ex-Dividend Date for such Spin-Off (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.


 




    	-51-



    	 



    

 


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 such Spin-Off, then, solely for purposes of determining the Conversion Consideration
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.


 


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.


 




    	-52-



    	 



    

 


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.


 


(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 (other than solely pursuant to an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under the Exchange
Act (or any successor rule)), and the value (determined as of the Expiration Time by the Company in good faith) 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 of the time such tender or exchange offer expires (the “Expiration Time”), of all cash and
    other consideration paid for shares of Common Stock purchased or exchanged in such tender or exchange offer (such aggregate value
    to be determined, other than with respect to cash, by the Company in good faith);


 


	 	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;


 




    	-53-



    	 



    

 


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. 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.


 


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.


 




    	-54-



    	 



    

 


(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)
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;


 


(2)
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;


 


(3)
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;


 


(4)
the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or exchangeable security of the Company
outstanding as of the Issue Date;


 


(5)
solely a change in the par value of the Common Stock; or


 


(6)
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 an aggregate 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 effective date of a Fundamental
Change or a Make-Whole Fundamental Change Effective Date; (iv) any Redemption Notice Date; and (v) September 1, 2026.


 


(D)
Adjustments Not Yet Effective. Notwithstanding anything to the contrary in this 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;


 




    	-55-



    	 



    

 


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


 


(E)
Conversion Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event. Notwithstanding anything
to the contrary in this 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) includes any whole shares of Common Stock
or due in respect of such VWAP Trading Day (in the case of Combination Settlement) includes any whole or fractional shares of Common
Stock, in each case 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 of Common Stock 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.


 




    	-56-



    	 



    

 


(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 this 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.


 


(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 this Indenture requires the Company to calculate the Last Reported
Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily Cash Amounts or the Daily Share Amounts over a period of multiple
days (including over an Observation Period and the period, if any, for determining the Stock Price for purposes of a Make-Whole Fundamental
Change), the Company will, acting in good faith and in a commercially reasonable manner, make appropriate adjustments, if any, to each
to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate
where the Ex-Dividend Date, effective date, or Expiration Date of the event occurs, at any time during such period.


 


(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 Section
5.05(A), 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.


 




    	-57-



    	 



    

 


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; and (ii) such increase is irrevocably in effect for a period of at least twenty (20) Business Days.


 


(B)
Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to Section 5.06(A),
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, 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:

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 straight-line interpolation between the numbers
of Additional Shares set forth for the higher and lower Stock Prices in the table above or the earlier and later dates in the table above,
based on a 365- or 366-day year, as applicable; and


 




    	-58-



    	 



    

 


(ii)
if the Stock Price is greater than $350.00 (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 $55.40 (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 this Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds
18.0505 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).


 


For
the avoidance of doubt, but subject to Section 4.03(J), (x) the sending of a Redemption Notice will constitute a Make-Whole Fundamental
Change only with respect to the Notes called (or deemed 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, except to the limited extent described in Section 4.03(J).


 


(B)
Adjustment of Stock Prices and Number of 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 5.05(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 connection with a Common Stock Change Event that also constitutes a Make-Whole Fundamental Change, then, pursuant to Section 5.09,
conversions of Notes will thereafter be settled no later than the second (2nd) Business Day after the relevant Conversion Date.

Section
5.08. Exchange in Lieu of Conversion.


 


Notwithstanding
anything to the contrary in this Article 5, and subject to the terms of this Section 5.08, if a Note is submitted for conversion,
the Company may elect to arrange to have such Note exchanged in lieu of conversion by a financial institution designated by the Company.
To make such election, the Company must send written notice of such election to the Holder of such Note, the Trustee and the Conversion
Agent before the Close of Business on the Business Day immediately following the Conversion Date for such Note. If the Company has made
such election, then:


 


(A)
no later than the Business Day immediately following such Conversion Date, the Company must deliver (or cause the Conversion Agent to
deliver) such Note, together with delivery instructions for the Conversion Consideration due upon such conversion (including wire instructions,
if applicable), to a financial institution designated by the Company that has agreed to deliver such Conversion Consideration (or such
other amount agreed to by such Holder and such financial institution) in the manner and at the time the Company would have had to deliver
the same pursuant to this Article 5;


 


(B)
if such Note is a Global Note, then (i) such designated institution will send written confirmation to the Conversion Agent promptly after
wiring the cash Conversion Consideration (or such other cash amount agreed to by such Holder and such financial institution), if any,
and delivering any other Conversion Consideration (or such other consideration agreed to by such Holder and such financial institution),
due to the Holder of such Note; and (ii) the Conversion Agent will as soon as reasonably practicable thereafter contact such Holder’s
custodian with the Depositary to confirm receipt of the same; and


 


(C)
such Note will not cease to be outstanding by reason of such exchange in lieu of conversion;


 


provided,
however, that if such financial institution does not accept such Note or fails to timely deliver such Conversion Consideration
(or such other amount agreed to by such Holder and such financial institution), then the Company will be responsible for delivering the
Conversion Consideration otherwise due upon conversion in the manner and at the time provided in this Article 5 as if the Company
had not elected to make an exchange in lieu of conversion. The Conversion Agent will be entitled to conclusively rely upon the Company’s
instruction in connection with effecting such exchange election and will have no liability in respect of such exchange election.


 


Section
5.09. 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;


 


(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; or


 


(iv)
other similar event,


 




    	-60-



    	 



    

 


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 this Indenture or the Notes,


 


(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 definitions of
“Fundamental Change” and “Make-Whole Fundamental Change,” references to “Common Stock” and the Company’s
“common equity” will be deemed to mean the 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 second (2nd) Business Day after the relevant Conversion Date (which cash will, for the avoidance
of doubt, be in an amount, per $1,000 principal amount of any Note being converted, equal to the product of (x) the Conversion Rate applicable
to such conversion (including any increase thereto pursuant to Section 5.07) and (y) the amount of cash constituting the Reference
Property Unit); 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, the Trustee and the Conversion
Agent (if other than the Trustee) in writing of such weighted average as soon as practicable after such determination is made.


 




    	-61-



    	 



    

 


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 5.09; (y) provide for subsequent adjustments to the Conversion Rate pursuant to
Section 5.05(A) in a manner consistent with this Section 5.09; and (z) contain such other provisions, if any, that the
Company reasonably determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions
of this Section 5.09(A). If the Reference Property includes shares of stock or other securities or assets (other than cash) 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, if any, that the Company reasonably determines are appropriate to preserve the economic
interests of the Holders.


 


(B)
Notice of Common Stock Change Events. The Company will provide notice of each Common Stock Change Event to Holders, the Trustee
and the Conversion Agent no later than the Business Day after the effective date of such Common Stock Change Event.


 


(C)
Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent with
this Section 5.09.


 


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 (directly, or indirectly through one or more of its
Subsidiaries) 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 pursuant to Section 8.01(E)) all of the Company’s obligations under this 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 this Indenture have been satisfied.


 




    	-62-



    	 



    

 


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 this Indenture and the Notes with the same effect as if
such Successor Corporation had been named as the Company in this Indenture and the Notes, and, except in the case of a lease, the predecessor
Company will be discharged from its obligations under this Indenture and the Notes.


 


Section
6.03. Exclusion for Asset Transfers with Wholly Owned Subsidiaries.


 


Notwithstanding
anything to the contrary in this Article 6, this Article 6 will not apply to any transfer of assets between or among the
Company and any one or more of its Wholly Owned Subsidiaries not effected by merger or consolidation.


 


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:

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

Section 5.01(C)(i)(3), or (z) a notice of a Make Whole Fundamental Change (other than a Make-Whole Fundamental Change pursuant
to clause (B) of the definition thereof) pursuant to the provisions referred to in Section 5.07(C), and, in the case of
clause (x) only, such failure is not cured within five (5) days after its occurrence;

(vi)
a default in any of the Company’s obligations or agreements under this Indenture or the Notes (other than a default set forth in

or waived within sixty (60) days after written 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”;


 




    	-63-



    	 



    

 


(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 fifty million
dollars ($50,000,000) (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


 


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


 


in
each case where such default is not cured or waived within thirty (30) 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;


 


(viii)
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)

is for relief against the 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;

    	-64-



    	 



    




 


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


 


(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)(viii) or 7.01(A)(ix)
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 further
action or notice by any Person.


 


(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)(viii) or 7.01(A)(ix) 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 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 this 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.


 




    	-65-



    	 



    

 


Section
7.03. Sole Remedy for a Failure to Report.


 


(A)
Generally. Notwithstanding anything to the contrary in this 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 will, for each of the first two hundred and seventy (270) 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 two hundred and seventy first (271st) 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 two hundred and seventy first (271st) calendar day
(it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.05(B)).


 


(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; provided, however,
that in no event will Special Interest, together with any Additional Interest, accrue on any day on a Note at a combined rate per annum
that exceeds one half of one percent (0.50%). 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 and, subject to the proviso of the immediately preceding sentence, in addition to any
Additional 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, before the date on which each Reporting Event of Default first occurs, a written 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 this Indenture
or the Notes.


 




    	-66-



    	 



    

 


(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.


 


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.


 


Subject
to the last sentence of this paragraph, 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, this Indenture or the Notes,
or that the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability. Prior
to taking any action under this Indenture, the Trustee is entitled to 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 this 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 written 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;


 




    	-67-



    	 



    

 


(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 this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another
Holder. The Trustee will have no duty to determine whether any Holder’s use of this Indenture complies with the preceding sentence.


 


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


 


Notwithstanding
anything to the contrary in this Indenture or the Notes (but without limiting Section 8.01), the right of each Holder of a Note
to bring suit for the enforcement of any 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 this Indenture and the Notes, 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 this 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.

Section
7.11. Priorities.


 


The
Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7:


 


First:
to the Trustee, the other Note Agents and each of their agents and attorneys for amounts due under Section 10.06, including payment
of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the Note Agents and the costs
and expenses of collection;


 


Second:
to Holders for unpaid amounts or other property due on the Notes, including the principal of, or the Redemption Price or Fundamental
Change Repurchase Price for, or any interest on, or any Conversion Consideration due upon conversion of, the Notes, ratably, and without
preference or priority of any kind, according to such amounts or other property due and payable on all of the Notes; and


 


Third:
to the Company or such other Person as a court of competent jurisdiction directs.


 


The
Trustee may fix a record date and payment date for any payment or delivery to the Holders pursuant to this Section 7.11, in which
case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record
date, to each Holder and the Trustee a notice stating such record date, such payment date and the amount of such payment or nature of
such delivery, as applicable.


 


Section

In
any suit for the enforcement of any right or remedy under this Indenture or the Notes or in any suit against the Trustee for any action
taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking
to pay the costs of such suit; and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party
in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided,
however, that this Section 7.12 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section
7.08 or any suit by one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding.

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 this Indenture or the Notes or waive compliance with any provision of this Indenture or the Notes. Notwithstanding anything
to the contrary in the foregoing sentence, but subject to Section 8.01, without the consent of each affected Holder, no amendment
or supplement to this Indenture or the Notes, or waiver of any provision of this 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 this 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 this 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 this Indenture or the Notes, or waiver of any provision of this 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.


 




    	-71-



    	 



    

 


Section
8.03. Notice of Amendments, Supplements and Waivers.


 


As
soon as reasonably practicable after any amendment, supplement or waiver pursuant to Section 8.01 or 8.02 becomes effective,
the Company will 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; provided, however, that the Company will not be required
to provide such notice to the Holders if such amendment, supplement or waiver is included in a periodic report filed by the Company with
the SEC within four (4) Business Days of its effectiveness. 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, notwithstanding anything to the contrary in Section 8.04(A), 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 this 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.


 


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 be entitled to receive, and (subject to Sections 10.01 and 10.02) will be fully protected in
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 this 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.


 


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


 


(A)
all Notes then outstanding (other than Notes replaced pursuant to Section 2.13) 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 2.13);


 


(C)
the Company has paid all other amounts payable by it under this Indenture; 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 this Indenture have been satisfied;


 


provided,
however, that Article 10 and Section 11.01 will survive such discharge and, until no Notes remain outstanding, Section
2.15 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.


 




    	-73-



    	 



    

 


At
the Company’s request, the Trustee will acknowledge the satisfaction and discharge of this Indenture.


 


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 this 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 of which a Responsible Officer of the Trustee has written notice or actual knowledge,
the Trustee will 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; provided
that the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction
of any of the Holders unless such Holders have offered, and if requested, provided, to the Trustee indemnity or security satisfactory
to Trustee against any loss, liability or expense that might be incurred by it in compliance with such request or direction.


 




    	-74-



    	 



    

 


(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 this Indenture, and the Trustee need perform only those
duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations will be read into this
Indenture against the Trustee; and


 


(ii)
in the absence of bad faith or willful misconduct 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 this Indenture. However, the Trustee will examine the certificates and opinions to determine
whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations
or other facts stated therein).


 


(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 this Indenture will require the Trustee to expend or risk its own funds or incur any liability in the performance of
any of its duties under this Indenture, or in the exercise of any of its rights or powers, if it has reasonable grounds to believe that
repayment of such funds or adequate indemnity against such liability is not reasonably assured to it.


 


(D)
Each provision of this 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)
No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability in the performance of
any of its duties or in the exercise of any of its rights or powers.


 


(F)
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.


 


(G)
Whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee will be subject to the provisions of this Section 10.01.


 


(H)
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 (except in its capacity as Paying Agent pursuant to the terms
of this Indenture) or any records maintained by any co-Note Registrar with respect to the Notes.


 




    	-75-



    	 



    

 


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


 


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


 


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.


 


(B)
Before the Trustee acts or refrains from acting, it may require, and may conclusively rely on, 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 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 this Indenture.


 


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


 


(F)
The Trustee need not exercise any rights or powers vested in it by this Indenture at the request or direction of any Holder unless such
Holder has offered, and if requested, provided 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, incidental or consequential loss or damage (including
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 Trustee will not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or
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 the Trustee will incur no liability or additional liability of any kind by reason of such inquiry or investigation.


 




    	-76-



    	 



    

 


(I)
The Trustee will not be deemed to have notice of any Default or Event of Default unless written notice of any event that is a Default
or Event of Default is received by a Responsible Officer of the Trustee at the corporate trust office of the Trustee, and such notice
references the Notes and this Indenture;


 


(J)
The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended
to, and will be enforceable by, the Trustee in each of its capacities under this Indenture.


 


(K)

at such time to take specified actions pursuant to this Indenture.

(M)
The Trustee will not be required to give any bond or surety in respect of the execution of the trusts and powers under this Indenture.


 


(N)
Neither the Trustee nor any Agent will have any responsibility or liability for any actions taken or not taken by the Depositary.


 


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 the same rights and duties as the trustee
under this Section 10.03.


 


Section
10.04. Trustee’s Disclaimer.


 


The
Trustee will not be (A) responsible for, and makes no representation as to, the validity or adequacy of this 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 this Indenture; (C) responsible for the use or application of any money received by any Paying Agent
other than the Trustee; and (D) responsible for any statement or recital in this Indenture, the Notes or any other document relating
to the sale of the Notes or this Indenture, other than the Trustee’s certificate of authentication.


 


Section
10.05. Notice of Defaults.


 


If
a Default or Event of Default occurs and is continuing of which a Responsible Officer of the Trustee has received written notice, 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 twenty (20) Business Days) after it becomes known to a Responsible Officer;
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, or a default in the payment or delivery of the Conversion Consideration, the Trustee may withhold such notice if and for
so long as it in good faith determines that withholding such notice is in the interests of the Holders.


 




    	-77-



    	 



    

 


Section
10.06. Compensation and Indemnity.


 


(A)
The Company will, from time to time, pay the Trustee and the Note Agents reasonable compensation for its acceptance of this Indenture
and services under this Indenture and the Notes as the Company and the Trustee will from time to time agree in writing. 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 this Indenture, including the reasonable compensation, disbursements and expenses of the Trustee’s
agents and counsel.


 


(B)
The Company will indemnify the Trustee (in each of its capacities) and its directors, officers, employees and agents, in their capacities
as such, against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration
of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including 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 this Indenture, except to the extent any such loss,
liability or expense may be attributable to its negligence or willful misconduct, as determined by a final, non-appealable order of 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), except to the extent
the Company is materially prejudiced by such failure. The Company will defend such claim, and the Trustee will cooperate in such defense.
If the Trustee is advised by counsel that it may have defenses available to it that are in conflict with the defenses available to the
Company, or that there is an actual or potential conflict of interest, then the Trustee may retain separate counsel, and the Company
will pay the reasonable fees and expenses of such counsel (including the reasonable fees and expenses of counsel to the Trustee incurred
in evaluating whether such a conflict exists). The Company need not pay for any settlement of any such claim made without its consent,
which consent will not be unreasonably withheld.


 


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


 


(E)
If the Trustee incurs expenses or renders services after an Event of Default pursuant to clause (viii) or (ix) 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)
Notwithstanding anything to the contrary in this Section 10.07, 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 this Indenture by so notifying the Company. The Holders
of a majority in aggregate principal amount of the Notes then outstanding may remove the Trustee by so notifying the Trustee and the
Company in writing. 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;


 


(iii)
a custodian or public officer takes charge of the Trustee or its property; or


 


(iv)
the Trustee becomes incapable of acting.


 


(C)
If the Trustee resigns or is removed, or if a vacancy exists in the office of the Trustee for any reason, then (i) the Company will promptly
appoint a successor Trustee; and (ii) at any time within one (1) year after the successor Trustee takes office, the Holders of a majority
in aggregate principal amount of the Notes then outstanding may appoint a successor Trustee to replace such successor Trustee appointed
by the Company.


 


(D)
If a successor Trustee does not take office within sixty (60) days after the retiring Trustee resigns or is removed, then the retiring
Trustee, the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the Notes then outstanding may petition
any court of competent jurisdiction for the appointment of a successor Trustee.


 


(E)
If the Trustee, after written request by a Holder of at least six (6) months (or, such lesser period since the Issue Date), fails to
comply with Section 10.09, then such Holder may petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.


 


(F)
A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company, upon which notice
the resignation or removal of the retiring Trustee will become effective and the successor Trustee will have all the rights, powers and
duties of the Trustee under this Indenture. The successor Trustee will send notice of its succession to Holders. The retiring Trustee
will, upon payment of all amounts due to it under this Indenture, promptly transfer all property held by it as Trustee to the successor
Trustee, which property will, for the avoidance of doubt, be subject to the lien provided for in Section 10.06(D).

10.08. Successor Trustee by Merger, Etc.


 


Any
organization or entity into which the Trustee may be merged or converted or with which it may be consolidated, or any organization or
entity resulting from any merger, conversion or consolidation to which the Trustee will be a party, or any organization or entity succeeding
to all or substantially all of the corporate trust business of the Trustee, will be the successor of the Trustee hereunder, provided
such organization or entity will be otherwise qualified and eligible under this Article 10, without the execution or filing of
any paper or any further act on the part of any of the parties hereto.


 


Section
10.09. Eligibility; Disqualification.

The
Company or the Trustee, by notice to the other, may designate additional or different addresses (including facsimile numbers and electronic
addresses) for subsequent notices or communications.


 


All
notices and communications (other than those sent to Holders) will be deemed to have been duly given: (A) at the time delivered by hand,
if personally delivered; (B) five (5) Business Days after being deposited in the mail, postage prepaid, if mailed; (C) when receipt acknowledged,
if transmitted by facsimile, electronic transmission or other similar means of unsecured electronic communication; and (D) the next Business
Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery.

guaranteeing next day delivery, to its address shown on the Register; provided, however, that a notice or communication
to a Holder of a Global Note may, but need not, instead be sent pursuant to the Depositary Procedures (in which case, such notice will
be deemed to be duly sent or given in writing). The failure to send a notice or communication to a Holder, or any defect in such notice
or communication, will not affect its sufficiency with respect to any other Holder.


 


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 this Indenture or the Notes, (A) whenever any provision of this 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;
and (B) whenever any provision of this Indenture requires a party to send notice to more than one receiving party, and each receiving
party is the same Person acting in different capacities, then only one such notice need be sent to such Person.
