pursuant to dissenters rights), in connection with such transaction or event, consists of shares of common stock or other corporate common
equity interests (exclusive of depositary receipts representing shares of common stock or other corporate common equity interests) listed

(without regard to the proviso in clause (B)) will be deemed to occur solely pursuant to clause (B) above (subject

principal U.S. national or regional securities exchange on which the Common Stock is then listed. If the Common Stock is not listed on

per share of Common Stock on such Trading Day in the over-the-counter market as reported by OTC Markets Group Inc. or a similar organization.
If the Common Stock is not so quoted on such Trading Day, then the Last Reported Sale Price will be the 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 recognized independent investment
banking firm selected by the Company, which may include any of the Initial Purchasers. Neither the Trustee nor the Conversion Agent will

occurs during the Make-Whole Fundamental Change Conversion Period for both a Make-Whole Fundamental Change occurring pursuant to clause
(A) of the definition of “Make-Whole Fundamental Change” and a Make-Whole Fundamental Change resulting from such
Redemption pursuant to clause (B) of such definition, then, notwithstanding anything to the contrary in Section 5.07,

Change Conversion Period for the Make-Whole Fundamental Change with the earlier Make-Whole Fundamental Change Effective Date; and (y) the

in accordance with Section 2.02(A); and (3) the Company delivers a Company Order to the Trustee that (a) requests
the Trustee to authenticate such Note; and (b) sets forth the name of the Holder of such Note and the date as of which such Note

Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. A duly appointed authenticating agent may

agent was validly appointed to undertake.

on a Redemption Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration
for, any Physical Note no later than the time the same is due as provided in this Indenture as follows: (i) if the principal amount
of such Physical Note is at least five million dollars ($5,000,000) (or such lower amount as the Company may choose in its sole and absolute
discretion) and the Holder of such Physical Note entitled to such payment has delivered to the Paying Agent or the Trustee, no later than
the time set forth in the immediately following sentence, a written request that the Company make such payment by wire transfer to an
account of such Holder within the United States, by wire transfer of immediately available funds to such account; and (ii) in all
other cases, by check mailed to the address of the Holder of such Physical Note entitled to such payment as set forth in the Register.
To be timely, such written request must be so delivered no later than the Close of Business on the following date: (x) with respect
to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular Record Date; (y) with respect to
any cash Conversion Consideration, the relevant Conversion Date; and (z) with respect to any other payment, the date that is fifteen

of Interest; Defaulted Amounts; When Payment Date is Not a Business Day.


 


(A)            Accrual
of Interest. Each Note will accrue interest at a rate per annum equal to 6.0% (the “Stated Interest”), 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(F) 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.


 






    - 16 -


    


    

 






 


(B)          Defaulted
Amounts. If the Company fails to pay any amount (a “Defaulted Amount”) payable on a Note on or before the due date
therefor as provided in 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.


 


(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

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.”


 


Section 2.06.    Registrar,

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


 


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


 


(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, except that the Registrar, Paying
Agent or Conversion Agent with respect to any Global Note must at all times be a Person that is eligible to act in that capacity under
the Depositary Procedures. 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.

(D)          Initial
Appointments. The Company appoints the Trustee as 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, then 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 the other provisions of this Indenture,


 


(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 2.12, 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 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, 2.16 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.


 


(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:


 


(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;


 






    - 20 -


    


    

 


(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, then the Company may (but is not required to) instruct the Trustee to cancel such Global Note pursuant to Section 2.14);


 


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


 


(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.


 


(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.


 






    - 21 -


    


    

 


(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 2.14;


 


(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;


 


(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 that is to be so transferred but that is not effected by notation as provided
above; and (y) bear each legend, if any, required by Section 2.09; and


 






    - 22 -


    


    

 


(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 to determine that such identification, removal or transfer, as applicable, complies with the Securities Act and
other applicable securities laws; provided, however, that, without limiting Section 2.10(E), no such
certificates, documentation or evidence (other than, in the case of the following clause (w), a written request in the form
contemplated by Section 2.10(E)) need be so delivered (w) in connection with any transfer pursuant to Rule 144 on or and
after the date that is six (6) months after the Last Original Issue Date of such Note if the requirements of
Rule 144(c) and (i) are then satisfied with respect to the Company; (x) in connection with any transfer of a
beneficial interest in a Global Note pursuant to Rule 144A; (y) in connection with any transfer of such Note to the
Company or one of its Subsidiaries; or (z) in connection with any transfer of such Note pursuant to an effective registration
statement under the Securities Act.


 






    - 23 -


    


    

 


(E)          Certain
De-Legending Procedures. If a Holder of any Note or share of Common Stock issued upon conversion of any Note, or an owner of a beneficial
interest in any Global Note, or in a global certificate representing any share of Common Stock issued upon conversion of any Note, transfers
such Note or share in compliance with Rule 144 and delivers to the Company a written request, certifying that it is not, and has
not been at any time during the preceding three (3) months, an Affiliate of the Company, to reissue such Note or share without a
Restricted Note Legend or Restricted Stock Legend, as applicable, then the Company will cause the same to occur (and, if applicable, cause
such Note or share to thereafter be represented by an “unrestricted” CUSIP or ISIN number in the facilities of the related
depositary), and will use its commercially reasonable efforts to cause such occurrence within two (2) Trading Days of such request.


 


(F)          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 or to Be Repurchased Pursuant to a Repurchase Upon Fundamental Change or Redemption.


 


(A)         Partial
Conversions of Physical Notes and Partial Repurchases of Physical Notes Pursuant to a Repurchase Upon Fundamental Change or Redemption.
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
or repurchase, as applicable, the Company will cause such Physical Note to be exchanged, pursuant and subject to Section 2.10(C),
for (i) one or more Physical Notes that are in Authorized Denominations and have an aggregate principal amount equal to the principal
amount of such Physical Note that is not to be so converted or repurchased, as applicable, and deliver such Physical Note(s) to such
Holder; and (ii) a Physical Note having a principal amount equal to the principal amount to be so converted or repurchased, as applicable,
which Physical Note will be converted or repurchased, as applicable, pursuant to the terms of 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 or repurchase, as applicable, is deemed to cease to be outstanding pursuant to Section 2.17.


 


(B)          Cancellation
of Notes that Are Converted and Notes that Are Repurchased Pursuant to a Repurchase Upon Fundamental Change or Redemption.


 






    - 24 -


    


    

 


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


 


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


 


Section 2.12.     Replacement
Notes.


 


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


 


Every replacement Note issued
pursuant to this Section 2.12 will be an additional obligation of the Company and will be entitled to all of the benefits
of this Indenture equally and ratably with all other Notes issued under this Indenture, whether or not the lost, destroyed or wrongfully
taken Note will at any time be enforceable by anyone.


 


Section 2.13.     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.


 






    - 25 -


    


    

 


Section 2.14.     Cancellation.


 


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


 


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


 


Without limiting the generality
of Section 2.17, in determining whether the Holders of the required aggregate principal amount of Notes have concurred in
any direction, waiver, 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, consent or other action, only Notes that a Responsible Officer of the Trustee knows are so owned will be
so disregarded.


 


Section 2.16.    Temporary
Notes.


 


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


 


Section 2.17.     Outstanding
Notes.


 


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


 






    - 26 -


    


    

 


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


 


(C)          Maturing
Notes and Notes Called for Redemption or Subject to Repurchase. If, 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 Section 4.02(D),
4.03(F) 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.


 


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


 


Section 2.18.     Repurchases
by the Company.


 


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


 


Section 2.19.     CUSIP
and ISIN Numbers.


 


The Company may use one or
more CUSIP or ISIN numbers to identify any of the Notes, and, if so, the Company and the Trustee will use such CUSIP or ISIN number(s) in
notices to Holders; provided, however, that (i) the Trustee makes no representation as to the correctness or accuracy
of any such CUSIP or ISIN number; and (ii) the effectiveness of any such notice will not be affected by any defect in, or omission
of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN number(s) identifying
any Notes.

Article 3.     Covenants


 


Section 3.01.     Payment
on Notes.


 


(A)          Generally.
The Company will pay or cause to be paid all the principal of, the Fundamental Change Repurchase Price and Redemption Price for, interest
on, and other amounts due with respect to, the Notes on the dates and in the manner set forth in this Indenture.


 


(B)          Deposit
of Funds. Before 11:00 A.M., New York City time, on each Redemption Date, Fundamental Change Repurchase Date or Interest Payment Date,
and on the Maturity Date or any other date on which any cash amount is due on the Notes, the Company will deposit, or will cause there
to be deposited, with the Paying Agent cash, in funds immediately available on such date, sufficient to pay the cash amount due on the
applicable Notes on such date. The Paying Agent will return to the Company, as soon as practicable, any money not required for such purpose.


 


Section 3.02.     Exchange
Act Reports.


 


(A)          Generally.
The Company will send to the Trustee copies of all reports that the Company is required to file with the SEC pursuant to Section 13(a) or
15(d) of the Exchange Act within fifteen (15) calendar days after the date that the Company is required to file the same (after giving
effect to all applicable grace periods under the Exchange Act); provided, however, that the Company need not send to the
Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by
the SEC. Any report that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be sent
to the Trustee at the time such report is so filed via the EDGAR system (or such successor). Delivery of reports, information and documents
to the Trustee is for informational purposes only and receipt of such reports and documents shall not constitute constructive notice of
any information contained therein or determinable from information contained therein, including the Company’s compliance with any
of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).
The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with the
covenants under this Indenture or the Notes or with respect to any reports or other documents filed with the SEC through the EDGAR system
or any website under this Indenture. Upon the request of any Holder, the Trustee will provide to such Holder a copy of any report that
the Company has sent the Trustee pursuant to this Section 3.02(A), other than a report that is deemed to be sent to the Trustee
pursuant to the preceding sentence.


 


(B)          Trustee’s
Disclaimer. The Trustee need not determine whether the Company has filed any material via the EDGAR system (or such successor). The
sending or filing of reports pursuant to Section 3.02(A) will not be deemed to constitute constructive notice to the
Trustee of any information contained, or determinable from information contained, therein, including the Company’s compliance with
any of its covenants under this Indenture.


 


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 Conversion Shares 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.


 






    - 28 -


    


    

 


Section 3.04.     Additional
Interest.


 


(A)          Accrual
of Additional Interest. If, on any day occurring on or after the date that is six (6) months after the Last Original Issue Date
of any Note,


 


(i)            the
Company has not satisfied the reporting conditions (including, for the avoidance of doubt, the requirement for current Form 10 information)
set forth in Rule 144(c) and (i)(2) under the Securities Act; or


 


(ii)           such
Note is not otherwise Freely Tradable,


 


then Additional Interest will accrue
on such Note for such day.


 


(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
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 that accrues pursuant to Section 7.03, accrue on any day on a Note at a combined rate per
annum that exceeds one percent (1.00%). 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 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 one hundred and twenty (120) days after December 31, 2022 and each fiscal year of the Company
ending thereafter, the Company will deliver an Officer’s Certificate to the Trustee stating (i) that the signatory thereto
has supervised a review 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).


 






    - 29 -


    


    

 


(B)          Default
Certificate. If a Default or Event of Default occurs, then the Company will, within thirty (30) days after its first occurrence, 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 3.07.     Acquisition
of Notes by the Company and its Affiliates.


 


Without limiting the generality
of Section 2.17, Notes that the Company or any of its Subsidiaries have purchased or otherwise acquired will be deemed to
remain outstanding (except to the extent provided in Section 2.15) until such time as such Notes are delivered to the Trustee
for cancellation. The Company will use commercially reasonable efforts to prevent any of its controlled Affiliates from acquiring any
Note (or any beneficial interest therein).


 


Article 4.     Repurchase
and Redemption


 


Section 4.01.     No
Sinking Fund.


 


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


 


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


 


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


 


(B)          Repurchase
Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not been
rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (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).


 






    - 30 -


    


    

 


(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.


 


(E)          Fundamental
Change Notice. On or before the twentieth (20th) calendar day after the effective date of a Fundamental Change, the Company will send
to each Holder, the Trustee and the Paying 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;


 






    - 31 -


    


    

 


(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;


 


(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.


 






    - 32 -


    


    

 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 


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


 






    - 33 -


    


    

 


(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 (i) one or more third parties conduct
any Repurchase Upon Fundamental Change and related offer to repurchase Notes otherwise required by this Section 4.02 in a
manner that would have satisfied the requirements of this Section 4.02 if conducted directly by the Company; and (ii) an
owner of a beneficial interest in any Note repurchased by such third party or parties will not receive a lesser amount (as a result of
withholding or similar taxes) than such owner would have received had the Company repurchased such Note.


 


(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 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 accrued and unpaid interest to, but excluding, the latest possible Fundamental Change Repurchase Date
for such Fundamental Change); and (iii) the Company timely sends the notice relating to such Fundamental Change required pursuant
to Section 5.01(C)(i)(3)(b) and includes, in such notice, a statement that the Company is relying on this Section 4.02(I).


 


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


 






    - 34 -


    


    

 


(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.


 


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


 


(A)         No
Right to Redeem Before May 20, 2025. The Company may not redeem the Notes at its option at any time before May 20, 2025.


 


(B)          Right
to Redeem the Notes on or After May 20, 2025. 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 described in Section 4.03(C))
in an Authorized Denomination, of the Notes, at any time, and from time to time, on a Redemption Date on or after May 20, 2025 and
on or before the 40th Scheduled Trading Day immediately before the Maturity Date, for a cash purchase price equal to the Redemption
Price, but only if (1) the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the
Conversion Price on (x) 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 (y) the
Trading Day immediately before such Redemption Notice Date and (2) the Liquidity Conditions have been satisfied. For the avoidance
of doubt, the calling of any Notes for Redemption will constitute a Make-Whole Fundamental Change with respect to such Notes pursuant
to clause (B) of the definition thereof.


 


(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 as a result of the payment of the related Redemption Price, and any related interest
pursuant to the proviso to the first sentence of Section 4.03(F), 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 sixty-five
(65), nor less than forty-five (45), Scheduled Trading Days after the Redemption Notice Date for such Redemption.


 






    - 35 -


    


    

 


(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 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 the first sentence of Section 4.03(F));


 


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


 


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


 


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


 


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


 


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


 






    - 36 -


    


    

 





 


On or before the Redemption
Notice Date, the Company will send a copy of such Redemption Notice to the Trustee and the Paying Agent.


 


(H)            Selection
and Conversion of Notes to Be Redeemed in Part.


 


(i)             If
less than all Notes then outstanding are called for Redemption, then the Notes to be redeemed will be selected 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 Trustee considers fair and appropriate.


 


(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 the first sentence of Section 4.03(F) 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 forty-second (42nd) Scheduled Trading Day immediately before the Redemption Date for such Redemption, whether
such Note or beneficial interest, as applicable, is to be redeemed pursuant to such Redemption, then such Holder or owner, as applicable,
will be entitled to convert such Note or beneficial interest, as applicable, at any time before the Close of Business on the Business
Day immediately before such Redemption Date, and each such conversion will be deemed to be of a Note called for Redemption for purposes
of this Section 4.03, Sections 5.01(C)(i)(4) and 5.07, and the definition of “Make-Whole Fundamental Change.”


 


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 Common Stock Sale Price Condition. A Holder may convert its Notes during any calendar quarter (and only during
such calendar quarter) commencing after the calendar quarter ending on June 30, 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. Neither the Trustee nor the Conversion Agent shall be responsible to determine whether such common stock sale
price condition has been satisfied.


 


(2)            Conversion
upon Satisfaction of Note Trading Price Condition. A Holder may convert its Notes during the five (5) consecutive Business Days
immediately after any 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. Neither the Trustee nor the
Conversion Agent shall be responsible to determine whether the Trading Price Condition has been satisfied.

(3)            Conversion
Upon Specified Corporate Events.


 


(a)            Certain
Distributions. If, before November 15, 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 record
date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the
Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading
Day immediately before the date such distribution is announced (determined in the manner set forth in the third paragraph of Section 5.05(A)(ii));
or


 


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


 


then, in either case, (x) the Company
will send notice of such distribution, and of the related right to convert Notes, to Holders, the Trustee and the Conversion Agent at
least forty-five (45) 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,
as soon as reasonably practicable 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 record date.


 






    - 39 -


    


    

 


(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 such effective date, then the last day on which the Notes are convertible pursuant to this sentence will be extended
by the number of Business Days from, and including, such effective date to, but excluding, the date the Company provides such notice.
No later than the second (2nd) Business Day after the effective date of any Fundamental Change, Make-Whole Fundamental Change or Common
Stock Change Event, the Company will send notice to the Holders, the Trustee and the Conversion Agent of such transaction or event, such
effective date and, if applicable, the related right to convert Notes.


 


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


 


(5)            Conversions
During Free Convertibility Period. A Holder may convert its Notes at any time from, and including, November 15, 2026 until the
Close of Business on the second (2nd) Scheduled Trading Day immediately before the Maturity Date.


 


For the avoidance of doubt, the Notes
may become convertible pursuant to any one or more of the preceding sub-paragraphs of this Section 5.01(C)(i) and the
Notes ceasing to be convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will not preclude the
Notes from being convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i).


 






    - 40 -


    


    

 


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


 


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


 


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


 


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


 


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


 


Section 5.02.     Conversion
Procedures.


 


(A)          Generally.


 


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


 


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


 


(B)           Effect
of Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion thereof) 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).


 






    - 41 -


    


    

 


(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 the last VWAP Trading Day of the Observation Period
for such conversion.


 


(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 (v) if the Company has specified a Redemption Date
that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; (w) if such
Conversion Date occurs after the Regular Record Date immediately before the Maturity Date; (x) if the Company has specified a Fundamental
Change Repurchase Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment
Date; or (y) to the extent of any overdue interest or interest that has accrued on any overdue interest. 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) solely cash as provided in Section 5.03(B)(i)(1) (a “Cash Settlement”);
or (y) 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)(2) (a “Combination Settlement”).


 


(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 November 15, 2026 will be
settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders, with a copy to the Trustee
and the Conversion Agent no later than the Open of Business on November 15, 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 November 15, 2026, then the Company will send notice of such Settlement Method to the Holder of such Note, with
a copy to the Trustee 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 on or after the related Redemption
Notice Date and on or before the Business Day before the related Redemption Date; and (b) if such Redemption Date occurs
on or after November 15, 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 November 15, 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


 






    - 43 -


    


    

 


(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, with a copy to the Trustee and the Conversion Agent, 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).


 


(ii)           The
Company’s Right to Irrevocably Fix or Eliminate the Settlement Methods. 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 (1) irrevocably
fix the Settlement Method that will apply to all conversions of Notes with a Conversion Date that occurs on or after the date such notice
is sent to Holders; or (2) irrevocably eliminate any one or more (but not all) Settlement Methods (including eliminating Combination
Settlement with a particular Specified Dollar Amount or range of Specified Dollar Amounts for all conversions of Notes with a Conversion
Date that occurs on or after the date such notice is sent to Holders); provided, in each case, that (v) in no event will the
Company elect (whether directly or by eliminating all other Settlement Methods) Combination Settlement with a Specified Dollar Amount
that is less than $1,000 per $1,000 principal amount of Notes; (w) 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)); (x) no such irrevocable election or Default Settlement
Method change will affect any Settlement Method theretofore elected (or deemed to be elected) with respect to any Note pursuant to this
Indenture (including pursuant to Section 8.01(G) or this Section 5.03(A)); (y) 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 fixed; and (z) 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. Such notice,
if sent, must set forth the applicable Settlement Method(s) so elected or eliminated, as applicable, and the Default Settlement Method
applicable immediately after such election and expressly state that the election is irrevocable and applicable to all conversions of Notes
with a Conversion Date that occurs on or after the date such notice is sent to Holders. For the avoidance of doubt, such an irrevocable
election, if made, will be effective without the need to amend 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).


 


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


 






    - 44 -


    


    

 


(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
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


 


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


 


(ii)            Cash
in Lieu of Fractional Shares. If 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) the Daily VWAP on the last
VWAP Trading Day of the Observation Period for such conversion.


 


(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 any Note is to be converted, then the Company will determine the Conversion Consideration
due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter send notice
to the Trustee and the Conversion Agent of the same and the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion
Agent will have any duty to make any such determination.


 


(C)           Delivery
of the Conversion Consideration. Except as set forth in Sections 5.05(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 on the second (2nd) Business Day immediately
after the last VWAP Trading Day of the Observation Period for such conversion.


 


(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.


 






    - 45 -


    


    

 


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 and not outstanding but unissued
shares of Common Stock that are not reserved for other purposes) a number of shares of Common Stock equal to the product of (i) the
aggregate principal amount (expressed in thousands) of all then-outstanding Notes (assuming the Initial Purchasers exercise the Shoe Option
in full); and (ii) the Conversion Rate for the Notes (assuming, for these purposes, that 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 authorized, 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:


 






    - 46 -


    


    

 





 


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


 


(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 record date of
such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last
Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day
immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula:


 





 


where:


 


	 	CR0	=	the Conversion
Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;
	 	 	 	 
	 	CR1	=	the Conversion
Rate in effect immediately after the Open of Business on such Ex-Dividend Date;



 






    - 47 -


    


    

 


		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.



 


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 increase
to the Conversion Rate for such distribution been made on the basis of only the rights, options or warrants, if any, actually distributed.
In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including
as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that
would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the number
of shares of Common Stock actually delivered upon exercise of such rights, option or warrants.


 


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
and in a commercially reasonable manner.


 


(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);


 






    - 48 -


    


    

 


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


 


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


 


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


 


(y)           a
distribution solely pursuant to a tender offer or exchange offer for shares of Common Stock, 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 and in a commercially reasonable manner), 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, and without having to convert its Notes, 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.


 






    - 49 -


    


    

 


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.



 






    - 50 -


    


    

 


Notwithstanding anything to the contrary
in this Section 5.05(A)(iii)(2), if any VWAP Trading Day of the Observation Period for a Note to be converted 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.


 


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, and without having to convert its Notes, 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.


 


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.


 






    - 51 -


    


    

 


(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), and the value (determined as of the Expiration Time by the Company in good faith and in a commercially reasonable manner) 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 (determined as of the time (the “Expiration Time”) such tender or exchange offer expires by the
Company in good faith and in a commercially reasonable manner) of all cash and other consideration paid for shares of Common Stock purchased
or exchanged in such tender or exchange offer;



 


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



 


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



 


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



 






    - 52 -


    


    

 


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), if any VWAP Trading
Day of the Observation Period for a Note to be converted 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.


 


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


 


(B)           No
Adjustments in Certain Cases.


 


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


 


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


 


(1)             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;


 






    - 53 -


    


    

 


(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 a change of at least one percent (1%) to the Conversion
Rate; (ii) the Conversion Date of, or any VWAP Trading Day of an Observation Period for, any Note; (iii) the date a Fundamental
Change or Make-Whole Fundamental Change occurs; (iv) the date the Company calls any Notes for Redemption; and (v) November 15,
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 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 any VWAP Trading Day in the Observation Period for such conversion, but an adjustment to the Conversion Rate for
such event has not yet become effective as of such VWAP Trading Day;


 


(iii)           the
Conversion Consideration due in respect of such VWAP Trading Day 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 VWAP Trading Day. In such case, if the date on which the
Company is otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such
adjustment can be determined, then the Company will delay the settlement of such conversion until the second (2nd) Business Day after
such first date.


 


(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:


 






    - 54 -


    


    

 


(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 Combination Settlement;


 


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


 


(iv)          the
Conversion Consideration due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock based on a Conversion
Rate that is adjusted for such dividend or distribution; and


 


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


 


then, the Conversion Rate adjustment relating
to such Ex-Dividend Date will be made for such conversion in respect of such VWAP Trading Day, but the shares of Common Stock issuable
with respect to such VWAP Trading Day based on such adjusted Conversion Rate will not be entitled to participate in such dividend or distribution.


 


(F)           Stockholder
Rights Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such conversion, the
Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently
with the delivery of, the Conversion Consideration otherwise payable under 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 potential readjustment in accordance with the last paragraph of Section 5.05(A)(iii)(1).


 


(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 average of the Last Reported
Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to the Conversion
Rate), or to calculate the Daily VWAPs, the Daily Conversion Values, the Daily Cash Amounts or the Daily Share Amounts over an Observation
Period, the Company will, if appropriate, make proportionate adjustments to such calculations to account for any adjustment to the Conversion
Rate that becomes effective, or any event requiring such an adjustment to the Conversion Rate where the Ex-Dividend Date, effective date
or Expiration Date, as applicable, of such event occurs, at any time during such period or Observation Period, as applicable.


 






    - 55 -


    


    

 


(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.


 


Section 5.06.     Voluntary
Adjustments.


 


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


 


(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:


 


	 	 	Stock

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


 


(ii)            if
the Stock Price is greater than $4.50 (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 $1.33 (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 751.8796 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.


 


(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 (i) occurring pursuant to clause (A) of the definition thereof in accordance with
Section 5.01(C)(i)(3)(b); and (ii) occurring pursuant to clause (B) of the definition thereof in accordance
with Section 4.03(G).

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 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 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, if any, and delivering any other Conversion Consideration, due upon such conversion 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, then the Company will be responsible
for delivering such Conversion Consideration 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.


 


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


 






    - 58 -


    


    

 


(iv)          other
similar event,


 


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 refer to the common equity (including depositary receipts
representing common equity), if any, forming part of such Reference Property;


 


(2)            if
such Reference Property Unit consists entirely of cash, then (I) each conversion of any Note with a Conversion Date that occurs on
or after the effective date of such Common Stock Change Event will be settled entirely in cash in an amount, per $1,000 principal amount
of such Note being converted, equal to the product of (x) the Conversion Rate in effect on such Conversion Date (including, for the
avoidance of doubt, any increase to such Conversion Rate pursuant to Section 5.07, if applicable); and (y) the amount
of cash constituting such Reference Property Unit; and (II) the Company will settle each such conversion no later than the tenth
(10th) Business Day after the relevant Conversion Date; and


 


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


 






    - 59 -


    


    

 


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 of such
weighted average as soon as practicable after such determination is made.


 


At or before the effective
time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common
Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture pursuant
to Section 8.01(F), which supplemental indenture will (x) provide for subsequent conversions of Notes in the manner set
forth in this Section 5.09; (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 in the manner provided in Section 5.01(C)(i)(3)(b).


 


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


 


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 Qualified Successor Entity
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.


 






    - 60 -


    


    

 


(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.


 


Section 6.02.      Qualified
Successor Entity Substituted.


 


At the effective time of any
Business Combination Event that complies with Section 6.01, the Qualified Successor Entity (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 Qualified
Successor Entity 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:


 


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


 


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


 


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


 


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


 


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


 






    - 61 -


    


    

 


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


 


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

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


 






    - 62 -


    


    

 


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


 


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


 


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


 


and, in each case under this Section 7.01(A)(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.


 






    - 63 -


    


    

 


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 one hundred and eighty (180) calendar days on which a Reporting
Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company
has made such an election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of
the relevant Reporting Event of Default from, and including, the one hundred and eighty first (181st) calendar day on which a Reporting
Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and
(ii) Special Interest will cease to accrue on any Notes from, and including, such one hundred and eighty first (181st) calendar
day (it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.05(B)).


 


(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
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 that accrues pursuant to Section 3.04(A), accrue on any day on a Note at a combined
rate per annum that exceeds one percent (1.00%). 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 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.


 






    - 64 -


    


    

 


(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.


 


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, subject to Section 10.01, the Trustee determines may be unduly prejudicial
to the rights of other Holders or may involve the Trustee in liability, unless the Trustee is offered security and indemnity satisfactory
to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction.


 


Section 7.07.      Limitation
on Suits.


 


No Holder may pursue any remedy
with respect to 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;


 


(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


 






    - 65 -


    


    

 


(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 (senior to the rights of Holders) 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.

suit; and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party in such suit, having

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 change 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.


 


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.


 






    - 69 -


    


    

 


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
the Trustee concludes 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 2.12) have (i) been delivered to the Trustee for
cancellation; or (ii) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the Maturity Date,
upon conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed;


 


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


 


(C)            the
Company has paid all other amounts payable by it under 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 Section 2.10(E),
Article 10 and Section 11.01 will survive such discharge and, until no Notes remain outstanding, Section 2.14
and the obligations of the Trustee, the Paying Agent and the Conversion Agent with respect to money or other property deposited with them
will survive such discharge.


 


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


 






    - 71 -


    


    

 


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, 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.


 


(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.


 


(C)            The
Trustee may not be relieved from liabilities for its negligence, bad faith 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; and


 






    - 72 -


    


    

 


(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.


 


(D)            Each
provision of this Indenture that in any way relates to the Trustee is subject to clauses (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.


 


(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)            Unless
a Responsible Officer of the Trustee has received notice from the Company that Additional Interest is owing on the Notes or that the Company
has elected to pay Special Interest on the Notes, the Trustee may assume no Additional Interest or Special Interest, as applicable, is
payable.


 


(H)            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, including as Note Agent.


 


(I)          
   The Trustee will not be charged with knowledge of any document or agreement other than
this Indenture and 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 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.


 






    - 73 -


    


    

 


(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 of the Company.


 


(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 the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense that it may incur in
complying with such request or direction.


 


(G)            The
Trustee will not be responsible or liable for any punitive, special, indirect or consequential loss or damage (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
permissive rights of the Trustee set forth in this Indenture will not be construed as duties imposed on the Trustee.


 


(I)            The
Trustee will not be required to give any bond or surety in respect of the execution or performance of this Indenture or otherwise.


 


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 and is known to a Responsible Officer of the Trustee, then the Trustee will send Holders a notice of such Default
or Event of Default within ninety (90) days after it occurs or, if it is not known to a Responsible Officer of the Trustee at such time,
promptly (and in any event within ten (10) 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, 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.
The Trustee will not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless written notice thereof
has been received by a Responsible Officer, and such notice references the Notes and this Indenture and states on its face that a Default
or Event of Default has occurred.

Section 10.06.    Compensation
and Indemnity.


 


(A)            The
Company will, from time to time, pay the Trustee reasonable compensation for its acceptance of this Indenture and services under this
Indenture, as separately agreed by the Company and the Trustee. 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
is attributable to its negligence, bad faith or willful misconduct, as determined by a final decision 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, 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.

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,

by the Company or the Trustee to the other will be deemed to have been duly given if in writing and delivered in person or by first class
mail (registered or certified, return receipt requested), facsimile transmission, electronic transmission or other similar means of unsecured
electronic communication or overnight air courier guaranteeing next day delivery, or to the other’s address, which initially is
as follows:

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.


 






    - 77 -


    


    

 


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.


 


The Trustee shall not have
any duty to confirm that the person sending any notice, instruction or other communication by electronic transmission (including by e-mail,
facsimile transmission, web portal or other electronic methods) is, in fact, a person authorized to do so. Electronic signatures believed
by the Trustee to comply with the ESIGN Act of 2000 or other applicable law (including electronic images of handwritten signatures and
digital signatures provided by DocuSign, Orbit, Adobe Sign or any other digital signature provider acceptable to the Trustee) shall be
deemed original signatures for all purposes. Each other party assumes all risks arising out of the use of electronic signatures and electronic
methods to send communications to the Trustee, including without limitation the risk of the Trustee acting on an unauthorized communication,
and the risk of interception or misuse by third parties. Notwithstanding the foregoing, the Trustee may in any instance and in its sole
discretion require that an original document bearing a manual signature be delivered to the Trustee in lieu of, or in addition to, any
such electronic communication.


 


All notices or communications
required to be made to a Holder pursuant to this Indenture must be made in writing and will be deemed to be duly sent or given in writing
if mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier 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.


 


Section 11.02.    Delivery

by the Company to the Trustee to take any action under this Indenture (other than the initial authentication of Notes under this Indenture),

Officer’s Certificate in form and substance reasonably satisfactory to the Trustee that complies with Section 11.03
and states that, in the opinion of the signatory thereto, all conditions precedent and covenants, if any, provided for in this Indenture
relating to such action have been satisfied; and


 


(B)            an
Opinion of Counsel in form and substance reasonably satisfactory to the Trustee that complies with Section 11.03 and states
that, in the opinion of such counsel, all such conditions precedent and covenants, if any, have been satisfied.


 


Section 11.03.    Statements
Required in Officer’s Certificate and Opinion of Counsel.


 


Each Officer’s Certificate
(other than an Officer’s Certificate pursuant to Section 3.05) or Opinion of Counsel with respect to compliance with
a covenant or condition provided for in this Indenture will include:


 


(A)            a
statement that the signatory thereto has read such covenant or condition;


 


(B)            a
brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained therein
are based;


 


(C)            a
statement that, in the opinion of such signatory, he, she or it has made such examination or investigation as is necessary to enable him,
her or it to express an informed opinion as to whether or not such covenant or condition has been satisfied; and


 


(D)            a
statement as to whether, in the opinion of such signatory, such covenant or condition has been satisfied.


 


Section 11.04.    Rules by
the Trustee, the Registrar, the Paying Agent and the Conversion Agent.

rules for action by or at a meeting of Holders. The Registrar, Paying Agent and Conversion Agent each may make reasonable rules and
set reasonable requirements for its functions.

director, officer, employee, incorporator or stockholder of the Company, as such, will have any liability for any obligations of the Company
under this Indenture or the Notes or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting
any Note, each Holder waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of
the Notes.


 


Section 11.06.    Governing
Law; Waiver of Jury Trial.


 


THIS INDENTURE AND THE NOTES,
AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS INDENTURE OR THE NOTES, WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE

courts of the United States of America located in the City of New York or the courts of the State of New York, in each case located in
the City of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the non-exclusive
jurisdiction of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail (to the
extent allowed under any applicable statute or rule of court) to such party’s address set forth in Section 11.01
will be effective service of process for any such suit, action or proceeding brought in any such court. Each of the Company, the Trustee
and each Holder (by its acceptance of any Note) irrevocably and unconditionally waives any objection to the laying of venue of any suit,
action or other proceeding in the Specified Courts and irrevocably and unconditionally waives and agrees not to plead or claim any such
suit, action or other proceeding has been brought in an inconvenient forum.


 


Section 11.08.    No
Adverse Interpretation of Other Agreements.


 


Neither this Indenture nor
the Notes may be used to interpret any other indenture, note, loan or debt agreement of the Company or its Subsidiaries or of any other
Person, and no such indenture, note, loan or debt agreement may be used to interpret this Indenture or the Notes.


 


Section 11.09.    Successors.


 


All agreements of the Company
in this Indenture and the Notes will bind its successors. All agreements of the Trustee in this Indenture will bind its successors.

in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee, like all financial institutions, in order to help fight the
funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity

as it may request to enable the Trustee to comply with the U.S.A. PATRIOT Act.

a schedule of its calculations to the Trustee and the Conversion Agent, and each of the Trustee and the Conversion Agent may rely conclusively
on the accuracy of the Company’s calculations without independent verification. The Trustee will promptly forward a copy of each
such schedule to a Holder upon its written request therefor. The Trustee will not be responsible for verifying such calculations.
