as provided in clause (i) or (ii) below:

 

(i)            
The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor

or any co-Note Registrar shall be required to exchange under this Section 2.05 or register a transfer of (i) any Notes surrendered

through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer
set forth herein) and the Applicable Procedures of the Depositary therefor.

 

(c)              Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c)

to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject
to the restrictions on transfer set forth in this Section 2.05(c) (including the legend set forth below), unless such restrictions

by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c)
and Section 2.05(d), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever

Company shall promptly notify the Trustee in writing after a registration statement, if any, with respect to the Notes or any shares of
the Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

 

Notwithstanding any other provisions of this Indenture
(other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except
(i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary
or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of
portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on
behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures
of the Depositary and in compliance with this Section 2.05(c).

 

The Depositary shall be a clearing agency registered
under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note.
Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary,
and deposited with the Trustee as custodian for Cede & Co.

 

If (i) the Depositary notifies the Company at
any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not
appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor
depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and
a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall
execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of
Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal
amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the
case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an
aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon
delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

 

    11

     

    

 

Physical Notes issued in exchange for all or a
part of the Global Notes pursuant to this Section 2.05(c) shall be registered in such names and in such authorized denominations
as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee in writing.
Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are
so registered.

 

At such time as all interests in a Global Note
have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in
accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation,
if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee who
receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of
such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian,
be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the
Custodian, at the direction of the Trustee, to reflect such reduction or increase.

 

None of the Company the Trustee or any agent of
the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership
interests.

 

(d)             
Until the date (the “Common Stock Resale Restriction Termination Date”) that is the later of (1) the date that
is one year after the issuance date of the relevant shares of the Common Stock or such shorter period of time as permitted by Rule 144
under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any
stock certificate representing shares of the Common Stock issued upon conversion of a Note shall bear a legend in substantially the following
form (unless the Note or such shares of the Common Stock has been transferred pursuant to a registration statement that has become or
been declared effective under the Securities Act and that continues to be effective at the time of such transfer or such shares of the
Common Stock have been transferred pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force
under the Securities Act, or unless otherwise agreed by the Company with written notice thereof to the Trustee and any transfer agent
for shares of the Common Stock):

 

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

 

(1)           
REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING
OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

 

(2)           
AGREES FOR THE BENEFIT OF BRAEMAR HOTELS & RESORTS INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE
OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE ISSUE
DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y)
SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

 

(A)        
TO THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

 

(B)         
PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

 

(C)         
TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

 

(D)         
PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM
THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

 

    12

     

    

 

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE
WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS
OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.

 

Any such shares of the Common Stock as to which
such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such
shares of the Common Stock for exchange in accordance with the procedures of the transfer agent for shares of the Common Stock, be exchanged
for a new certificate or certificates for a like aggregate number of shares of the Common Stock, which shall not bear the restrictive
legend required by this Section 2.05(d). The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance
with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in
any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Note) other
than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when
expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof.

 

Section 2.06.         
Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen,
the Company in its discretion may execute, and upon receipt of a Company Order the Trustee or an authenticating agent appointed by the
Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution
for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case, the applicant for
a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution,
and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable,
to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

 

The Trustee or such authenticating agent may authenticate
any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable,
such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note
Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to
cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of
the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen.
In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in
accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead
of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof
except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company,
to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of
them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction,
loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent of the destruction,
loss or theft of such Note and of the ownership thereof.

 

Every substitute Note issued pursuant to the provisions
of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all
the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all
other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the
foregoing provisions are exclusive with respect to the replacement, payment, conversion, redemption or repurchase of mutilated, destroyed,
lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement, payment, conversion, redemption or repurchase of negotiable instruments or other
securities without their surrender.

 

Section 2.07.          Temporary
Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent
appointed by the Trustee shall, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed).
Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such
omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such
temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the
Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and
thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency
maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and
deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by
the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered
hereunder.

 

    13

     

    

 

Section 2.08.         
Cancellation of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment,
repurchase, conversion, redemption, registration of transfer of Notes or exchange of Notes for other Notes or in accordance with Article
14, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates),
to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it, and no Notes shall
be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose
of canceled Notes in accordance with its customary procedures and shall deliver a certificate of such disposition to the Company, at the
Company’s written request.

 

Section 2.09.         
CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that
any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such
notice and that reliance may be placed only on the other identification numbers printed on the Notes, and any such notices shall not be
affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP”
numbers.

 

Section 2.10.         
Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section
2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other
than differences in the issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal
amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income
tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company
shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate
and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request.
In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered
to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or
public tender or exchange offer or through counterparties pursuant to private agreements, including by cash-settled swaps or other cash-settled
derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives)
to be surrendered to the Trustee for cancellation in accordance with Section 2.08.

 

Section 2.11.         
Ranking. The obligations of the Company arising under or in connection with this Indenture and every outstanding
Note issued under this Indenture from time to time constitute and shall constitute a general unsecured senior obligation of the Company,
ranking equally with existing and future senior unsecured indebtedness of the Company and ranking senior in right of payment to any existing
and future indebtedness of the Company that is expressly made subordinate to the Notes by the terms of such indebtedness.

Section 3.01.         
Satisfaction and Discharge of the Indenture. When (i) the Company shall deliver to the Trustee for cancellation all
Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in substitution for which
other Notes shall have been authenticated and delivered or paid pursuant to Section 2.06) and not theretofore canceled, or (ii)
all such Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable (whether on the

and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, an amount of cash and/or (in the case

been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered
or paid pursuant to Section 2.06) not theretofore canceled or delivered to the Trustee for cancellation, including principal and
interest due, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then the Indenture
shall cease to be of further effect with respect to the Notes (except as to (i) rights hereunder of Holders to receive all amounts owing
upon the Notes and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (ii) the rights, obligations and immunities of the Trustee under the Indenture), and the Trustee, on written
demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
herein provided for relating to the satisfaction and discharge of the entire indebtedness on the Notes have been complied with, and at
the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture with respect
to the Notes; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly
incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably
and properly rendered by the Trustee in connection with the Indenture or the Notes.

Section 3.02.          Deposited
Monies to Be Held in Trust by Trustee. Subject to Section 4.04(d) hereof, all monies and shares of the Common Stock, if
any, deposited with the Trustee pursuant to Section 3.01 hereof shall be held in trust for the sole benefit of the Holders of
the Notes, and such monies and shares of the Common Stock shall be applied by the Trustee to the payment, either directly or through
any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Notes for the payment or
settlement of which such monies or shares of the Common Stock have been deposited with the Trustee, of all sums or amounts due and to
become due thereon for principal and interest, if any.

 

Section 3.03.          Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of the Indenture with respect to the Notes,
all monies and shares of the Common Stock, if any, then held by any Paying Agent (if other than the Trustee) with respect to the Notes
shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released
from all further liability with respect to such monies and shares of the Common Stock.

 

Section 3.04.         
Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of the Common Stock in accordance
with Section 3.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be revived and reinstated as though
no deposit had occurred pursuant to Section 3.01 until such time as the Trustee or the Paying Agent is permitted to apply all such
money and shares of the Common Stock in accordance with Section 3.02; provided, however, that if the Company makes any payment
of interest on, principal of or payment or delivery in respect of any Note following the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or shares of the Common Stock, if
any, held by the Trustee or Paying Agent.

PARTICULAR COVENANTS OF THE COMPANY

 

Section 4.01.         
Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal (including
the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the
respective times and in the manner provided herein and in the Notes.

 

Section 4.02.         
Maintenance of Office or Agency. The Company will maintain in the continental United States an office or agency where
the Notes may be surrendered for registration of transfer of Notes or exchange of Notes for other Notes or for presentation for payment
or repurchase (“Paying Agent”) or for conversion in accordance with Article 14 (“Conversion Agent”)
and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by
the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the
office or agency of the Trustee in the Borough of Manhattan, The City of New York.

 

The Company may also from time to time designate
as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in the continental United States for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The
terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

 

The Company hereby initially designates the Trustee
as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency in the continental
United States where Notes may be surrendered for registration of transfer of Notes or exchange of Notes for other Notes or for presentation
for payment or repurchase or for conversion in accordance with Article 14.

 

Section 4.03.         
Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy
in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be
a Trustee hereunder.

 

Section 4.04.         
Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company
will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section 4.04:

 

(i)            
that it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and the Fundamental
Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the
Notes;

 

    15

     

    

 

(ii)           
 that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including the
Redemption Price and the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the
same shall be due and payable; and

 

(iii)          
that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee
all sums so held in trust.

 

The Company shall, on or before each due date of
the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest
on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Redemption Price and the Fundamental
Change Purchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received
by the Paying Agent by 11:00 a.m., New York City time, on such date.

 

(b)             
If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption
Price and the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate
and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price and
the Fundamental Change Purchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee
in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Redemption
Price and the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become
due and payable.

 

(c)             
Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining
a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts
held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by
the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the
Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

 

(d)             
Any money and shares of the Common Stock deposited with the Trustee or any Paying Agent, or then held by the Company, in trust
for the payment of the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, accrued
and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal
(including the Redemption Price and the Fundamental Change Purchase Price, if applicable), interest or consideration due upon conversion
has become due and payable shall, subject to applicable escheat laws, be paid to the Company on request of the Company contained in an
Officers’ Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money and shares of the Common Stock, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that prior to the Trustee or such Paying Agent making any such repayment, the Company shall publish in a newspaper
of general circulation in New York City or publish such information on the Company’s website or through such other public medium
as the Company deems appropriate at that time, a notice that such money and shares of the Common Stock remain unclaimed and that, after
a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money
and shares of the Common Stock then remaining will be repaid or delivered to the Company.

 

Section 4.05.         
Existence. Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve
and keep in full force and effect its existence.

 

Section 4.06.         
Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to Section 13 or
15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of the Common Stock issuable upon conversion
thereof will, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities
Act, promptly furnish to the Holders, beneficial owners and prospective purchasers of the Notes and of any shares of the Common Stock
delivered upon conversion of the Notes, upon their written request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act to facilitate the resale of the Notes and such shares of the Common Stock pursuant to Rule 144A. The Company
shall take such further action as any Holder or beneficial owner of such Notes may reasonably request to the extent from time to time
required to enable such Holder or beneficial owner to sell such Notes or shares of the Common Stock in accordance with Rule 144A, as
such rule may be amended from time to time.

 

(b)              The
Company shall file with the Trustee, within 15 days after the same are required to be filed with the Commission, copies of any
documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act
(giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company
files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be filed with the
Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system (or such successor
thereto); provided, however, that the Trustee shall have no responsibility whatsoever to determine if such filing has occurred.

 

    16

     

    

 

(c)             
Delivery of the reports and documents described in subsection (b) above to the Trustee is for informational purposes only, and
the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is
entitled to conclusively rely on an Officers’ Certificate). The Trustee shall not be obligated to monitor or confirm, on a continuing
basis or otherwise, the Company’s compliance with such covenants or with respect to any reports or other documents filed with the
SEC or EDGAR or any website under the Indenture or participate in any conference calls.

 

(d)              If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original
issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant
to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than
reports on Form 8-K), or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates
or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions
pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes.
Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for
each day during such period for which the Company’s failure to file has occurred and is continuing or the Notes are not otherwise

after the last date of original issuance of the Notes (unless such Legend Removal Deadline falls between a Regular Record Date and an
Interest Payment Date, in which case the Legend Removal Deadline shall be the 10th day following the relevant Interest Payment Date),
the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding
until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted
CUSIP and the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were
the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities
laws or the terms of this Indenture or the Notes.

 

(f)              
Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest
on the Notes.

 

Section 4.07.         
Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall 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
or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this
Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and
covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee,
but will suffer and permit the execution of every such power as though no such law had been enacted.

 

Section 4.08.         
Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 days after
the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2021) an Officers’ Certificate
stating (1) that a review has been conducted of the activities of the Company, its Subsidiaries and of the Company and their respective
performance under this Indenture and (2) that the Company has fulfilled all obligations under this Indenture (such compliance to be determined
without regard to any period of grace or requirement of notice provided under this Indenture) or specifying any Event of Default and the
nature thereof.

 

In addition, the Company shall deliver to the Trustee
within 30 days after an Officer of the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’
Certificate setting forth the details of such Default or Event of Default, its status and the action that the Company is taking or proposing
to take in respect thereof.

 

Section 4.09.          Additional
Interest Notice. If Additional Interest is payable by the Company pursuant to Section 4.06 or Section 6.03,
the Company shall deliver to the Trustee at least ten (10) calendar days prior to the applicable payment date an Officers’
Certificate to that effect stating (a) the amount of such Additional Interest that is payable and (b) the date on which such
interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a
certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional
Interest directly to the Persons entitled to them, the Company shall deliver to the Trustee promptly following such payment an
Officers’ Certificate setting forth the particulars of such payment.

 

    17

     

    

 

Section 4.10.         
Covenant to Take Certain Actions. Before taking any action which would cause an adjustment to the Conversion Rate
such that the Conversion Price per share of the Common Stock issuable upon conversion of the Notes would be less than the par value of
shares of the Common Stock, the Company shall take all corporate actions that may, in the opinion of its counsel, be necessary so it may
validly and legally issue shares of the Common Stock at such adjusted Conversion Rate.

or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive days.

 

Section 6.02.          Acceleration; Rescission and Annulment.

 

(a)             
If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether
it shall be voluntary or involuntary or be 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), then, and in each and every such case (other than an Event of Default
specified in Section 6.01(j) or Section 6.01(k) with respect to the Company (and not solely with respect to a Significant
Subsidiary of the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or
the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice in writing to the Company (and to the
Trustee if given by the Holders), may declare 100% of the principal of, and accrued and unpaid interest, if any, on all the Notes to be
due and payable immediately.

 

(b)             
If an Event of Default specified in Section 6.01(j) or Section 6.01(k) with respect to the Company (and not solely
with respect to a Significant Subsidiary of the Company) occurs and is continuing, the principal of, and accrued and unpaid interest,
if any, on all Notes shall be immediately due and payable.

 

Section 6.03.         
Additional Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the
Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set
forth in Section 4.06(b) (a “Reporting Event of Default”) shall after the occurrence of such an Event of Default
consist exclusively of the right to receive additional interest (the “Additional Interest”) on the Notes at a rate
equal to (i) 0.25% per annum of the principal amount of the Notes outstanding the first 90 days of the 180-day period on which such Event
of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum
of the Outstanding principal amount of the Notes for the last 90 days of such 180-day period as long as such Event of Default is continuing
beginning on and including the 91st day after such Event of Default. If the Company so elects, such Additional Interest shall be payable
in the same manner and on the same dates as the stated interest payable on the Notes; provided that in no event shall Additional Interest
pursuant to this Section 6.03 accrue at a rate, in the aggregate, in excess of 0.50% per annum regardless of the number of events
or circumstances giving rise to the requirement to pay such Additional Interest pursuant to this Section 6.03. On the 181st day
after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations as set forth
in Section 4.06(b) is not cured or waived prior to such 181st day), the Notes shall be immediately subject to acceleration as provided
in Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance
with this Section 6.03 or the Company elects to make such payment but does not pay the Additional Interest when due, the Notes
shall be immediately subject to acceleration as provided in Section 6.02. If the Company elects to pay additional interest in accordance
with this Section 6.03, the Company shall deliver to the Trustee an Officer’s Certificate (upon which the Trustee may rely
conclusively) to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional
Interest is payable. Unless and until the Trustee receives such Officer’s Certificate, the Trustee may assume without inquiry that
no such Additional Interest is payable and the Trustee shall not have any duty to verify the Company’s calculations of Additional
Interest.

 

In order to elect to pay the Additional Interest
as the sole remedy during the first 180 days after the occurrence of a Reporting Event of Default, the Company must notify all Holders
of Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the Company’s failure
to timely give such notice, the Notes will be immediately subject to acceleration as provided in Section 6.02.

 

Section 6.04.          Payments
of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 6.01 shall have
occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole
amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if
any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any
amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so
due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other
obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of
the Company or any other obligor upon the Notes, wherever situated. Until such demand by the Trustee, the Company may pay the
principal and interest, if any, on the Notes to the registered Holders, whether or not the Notes are overdue.

 

    19

     

    

 

In the event there shall be pending proceedings
for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code,
or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar
official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other
obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors
or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant
to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file
and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in
case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may
deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee and its counsel) and of the Holders allowed in such judicial proceedings relative to the Company
or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property
payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section
7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized
by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent
to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses,
advances and disbursements, including counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred
by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements
out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall
be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled
to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

 

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

 

All rights of action and of asserting claims under
this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production
thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought
in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee and its counsel, be for the ratable benefit of the Holders of the Notes.

 

In any proceedings brought by the Trustee (and
in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee
shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any
such proceedings.

 

In case the Trustee shall have proceeded to enforce
any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section
6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely
to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding,
be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders
and the Trustee shall continue as though no such proceeding had been instituted.

 

Section 6.05.          Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 6
shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation
of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

 

First, to the payment of all amounts due
the Trustee under Section 7.06;

 

Second, in case the principal of the outstanding
Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default
in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the
extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such
payments to be made ratably to the Persons entitled thereto;

 

Third, in case the principal of the
outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including,
if applicable, the payment of the Redemption Price and the Fundamental Change Purchase Price and any cash due upon conversion) then
owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that
such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time,
and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment
of such principal (including, if applicable, the Redemption Price and the Fundamental Change Purchase Price and the cash due upon
conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any
installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such
principal (including, if applicable, the Redemption Price the Fundamental Change Purchase Price and any cash due upon conversion)
and accrued and unpaid interest; and

 

    20

     

    

 

Fourth, to the payment of the remainder,
if any, to the Company.

 

Section 6.06.         
Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the
Redemption Price and the Fundamental Change Purchase Price) or interest when due, or the right to receive payment or delivery of the consideration
due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver,
trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

 

(a)             
such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as
herein provided;

 

(b)              Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee
to institute such action, suit or proceeding in its own name as Trustee hereunder;

 

(c)             
such Holder or Holders shall have offered to the Trustee such indemnity or security reasonably satisfactory to it against any costs,
liabilities or expenses to be incurred in compliance with such request;

 

(d)             
the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute
any such action, suit or proceeding; and

 

(e)             
during such 60-day period, no direction that is inconsistent with such written request shall have been given to the Trustee by
the Holders of a majority of the aggregate principal amount of the Notes then outstanding pursuant to Section 6.09,

 

it being understood and intended, and being expressly covenanted by
the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right
in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any
other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances
are unduly prejudicial to such Holder), or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce
any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except
as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

 

Notwithstanding any other provision of this Indenture
and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including
the Fundamental Change Purchase Price, the Redemption Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the
consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this
Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates
against the Company shall not be impaired or affected without the consent of such Holder.

 

Section 6.07.         
Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement
of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce
any other legal or equitable right vested in the Trustee by this Indenture or by law.

 

Section 6.08.         
Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, all powers and
remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and
not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings
or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any continuing Default or continuing
Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or
any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6
or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee
or by the Holders.

 

    21

     

    

 

Section 6.09.          Direction
of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of
the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee
with respect to the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture,
and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee
may refuse to follow any direction that it determines in good faith is unduly prejudicial to the rights of any other Holder or that would
involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding
determined in accordance with Section 8.04 may on behalf of the Holders of all of the Notes waive any past Default or Event of
Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal
(including the Redemption Price or the Fundamental Change Purchase Price) of, the Notes when due that has not been cured, (ii) a failure
by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect
of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an
outstanding Note affected. Upon any such waiver, the Company, the Trustee and the Holders of the Notes shall be restored to their former
positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any
right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09,
said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing;
but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

 

Section 6.10.         
Notice of Defaults. The Trustee shall, within 90 days after a Responsible Officer has received written notice of
the occurrence and continuance of a Default, send to all Holders as the names and addresses of such Holders appear upon the Note Register,
notice of all such Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of
such notice; provided that, except in the case of a Default in the payment of the principal of (including the Redemption Price and the
Fundamental Change Purchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or
delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the board
of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interests of the Holders.

 

Section 6.11.         
Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including
reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith
of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted
by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the

CONCERNING THE TRUSTEE

 

Section 7.01.         
Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the
curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically
set forth in this Indenture. In the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights
and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person’s own affairs; provided that if an Event of Default occurs and is continuing,
the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any
of the Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against all losses
and expenses that might be incurred by it in compliance with such request or direction.

 

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

 

(a)          
prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

 

(i)            the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee
shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and

 

    22

     

    

 

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

 

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

 

(c)          
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with
the direction of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined
as provided in Section 8.04 relating to the time, method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

 

(d)          
whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording
protection to, the Trustee shall be subject to the provisions of this Section 7.01;

 

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

 

(f)           
in the absence of specific written investment direction from the Company, all cash received by the Trustee shall be placed in a
non-interest bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses
incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or the failure
of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely
written investment direction, and the Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence
of such specific written investment direction from the Company; and

 

(g)          
in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent or transfer agent hereunder,
the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar,
Paying Agent, Conversion Agent or transfer agent.

 

None of the provisions contained in this Indenture
shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of
its duties or in the exercise of any of its rights or powers.

 

Section 7.02.         
Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01:

 

(a)          
the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement, instrument,

and to have been signed or presented by the proper party or parties;

any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers’ Certificate

to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company or the Company;

 

(c)          
the Trustee may consult with counsel of its selection and require an Opinion of Counsel and any advice of such counsel or Opinion
of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith
and in accordance with such advice or Opinion of Counsel;

 

(d)          
the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee,
in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or
investigation;

 

(e)          
the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through
agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any
agent, custodian, nominee or attorney appointed by it with due care hereunder;

 

(f)           
the permissive rights of the Trustee enumerated herein shall not be construed as duties;

 

    23

     

    

 

(g)          
 in no event shall the Trustee be liable for any indirect, special, consequential or punitive loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless
of the form of action;

 

(h)          
the Trustee shall not be charged with knowledge of any Default, Event of Default or any other default with respect to the Notes,
unless written notice from the Company or any Holder of the Notes of such Default or Event of Default shall have been received by a Responsible
Officer of the Trustee;

 

(i)           
the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder;

 

(j)           
the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture; and

 

(k)           Unless a Responsible Officer of the Trustee has received an Officer’s Certificate with respect thereto, the Trustee may assume
that no Additional Interest is owed on the Notes.

 

Section 7.03.         
No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s
certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness
of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall
not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

 

Section 7.04.         
Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion
Agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would
have if it were not the Trustee, Paying Agent, Conversion Agent or Note Registrar.

 

Section 7.05.         
Monies and Shares of the Common Stock to Be Held in Trust. All monies and shares of the Common Stock received by
the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money and
shares of the Common Stock held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money or shares of the Common Stock received by it hereunder except
as may be agreed from time to time by the Company and the Trustee.

 

Section 7.06.         
Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and
the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between
the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements
and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder
(including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ)
except any such expense, disbursement or advance as shall have been caused by its negligence, willful misconduct or bad faith. The Company
also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection
herewith and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without
negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors or employees, or such authenticating agent,
as the case may be, and arising out of or in connection with the acceptance or administration of this Indenture or in any other capacity
hereunder, including the reasonable costs and expenses of defending themselves against any claim of liability in the premises. The obligations
of the Company under this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property
held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of
the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this Section 7.06 shall
not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company under this Section 7.06
shall survive the satisfaction and discharge of this Indenture and the earlier resignation or removal or the Trustee. The Company need
not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in
this Section 7.06 shall extend to the officers, directors and employees of the Trustee.

 

Without prejudice to any other rights available
to the Trustee under applicable law, when the Trustee and any authenticating agent incur expenses or render services after an Event of
Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended
to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

 

Section 7.07.          Officers’
Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking
or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in
the absence of negligence, willful misconduct and bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of
negligence, willful misconduct and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken
or omitted by it under the provisions of this Indenture upon the faith thereof.

 

    24

     

    

 

Section 7.08.         
Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes
reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the
purposes of this Section 7.08, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 7.08, it shall resign immediately in the manner and with the effect hereinafter specified in
this Article 7.

 

Section 7.09.         
Resignation or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation
to the Company. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument,
in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and
one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment within 60 days,
the resigning Trustee may, upon 10 Business Days’ notice to the Company, petition at the expense of the Company any court of competent
jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least
six months may, subject to the provisions of Section 6.11, on behalf of himself or herself and all others similarly situated, petition
any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper
and prescribe, appoint a successor trustee.

 

(b)          
In case at any time any of the following shall occur:

 

(i)           
the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after
written request therefor by the Company or by any such Holder, or

 

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

 

then, in either case, the Company may by a Board Resolution remove
the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy
of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions
of Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself
or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

 

(c)          
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with
Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee
unless within 10 days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed
or any Holder, upon the terms and conditions and otherwise as in Section 7.09(b) provided, may, at the expense of the Company,
petition any court of competent jurisdiction for an appointment of a successor trustee.

 

(d)          
Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section
7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10.

 

Section 7.10.            
Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon
the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect
as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an
instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the
Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for
the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06.

 

    25

     

    

 

No successor trustee shall accept appointment as
provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions
of Section 7.08.

 

Upon acceptance of appointment by a successor trustee
as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of
the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders at their addresses as they
shall appear on the Note Register. If the Company fails to mail such notice within 10 days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

 

Section 7.11.         
Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee
(including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any
paper or any further act on the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding
to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the
provisions of Section 7.08.

 

In case at the time such successor to the Trustee
shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor
to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor
trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor
to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor
trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it
is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right
to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee
shall apply only to its successor or successors by merger, conversion or consolidation.

 

Article

CONCERNING THE HOLDERS

 

Section 8.01.         
Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the aggregate
principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or
waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage
have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by Holders in person or
by agent or proxy appointed in writing. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes,
the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for determining
Holders entitled to take such action. The record date if one is selected shall be not more than 15 days prior to the date of commencement
of solicitation of such action.

 

Section 8.02.         
Proof of Execution by Holders. Subject to the provisions of Section 7.01 and Section 7.02, proof of
the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules
and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall
be proved by the Note Register or by a certificate of the Note Registrar.

 

Section 8.03.          Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion
Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat
it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other
writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account
of the principal of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for
all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall
be affected by any notice to the contrary. All such payments or deliveries so made to any Holder for the time being, or upon its order,
shall be valid, and, to the extent of the sums or shares of the Common Stock so paid or delivered, effectual to satisfy and discharge
the liability for monies payable or shares deliverable upon any such Note. Notwithstanding anything to the contrary in this Indenture
or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the Company,
without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s
right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of this Indenture.

 

Section 8.04.          Company-Owned
Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in
any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary of the
Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the
Company or any Subsidiary of the Company shall be disregarded and deemed not to be outstanding for the purpose of any such
determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such
direction, consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so
disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section
8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such
Notes and that the pledgee is not the Company, a Subsidiary of the Company or a Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any Subsidiary of the Company. In the case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request
of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes,
if any, known by the Company to be owned or held by or for the account of any of the above-described Persons; and, subject to Section
7.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set
forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

 

    26

     

    

 

Section 8.05.         
Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee,
as provided in Section 8.01, of the taking of any action by the Holders of the percentage of the aggregate principal amount of
the Notes specified in this Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included
in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust
Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid,
any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners
of such Note and of any Notes issued in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether
any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of
transfer thereof.

impair the right of any Holder of Notes to receive payment of principal of, and interest, if any, on, its Notes, or the right to
receive payment of cash and, if applicable, shares of the Common Stock or other consideration, together with cash in lieu thereof in respect
of any fractional shares, due upon conversion of its Notes on or after the due dates therefor or to institute suit for the enforcement
of any such payment or delivery, as the case may be, with respect to such Holder’s Notes;

 

(i)              
modify the ranking provisions of the Indenture in a manner that is adverse to the rights of the Holders of the Notes; or

 

(j)              
make any change to the provisions of this Article 10 that requires each Holder’s consent or in the waiver provisions
in Section 6.09 if such change is adverse to the rights of Holders of the Notes.

 

It shall not be necessary for any act or consent
of Holders under this Section 10.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient
if such act or consent shall approve the substance thereof. The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the Holders on
such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture,
whether or not such Holders remain Holders after such record date; provided that, unless such consent shall have become effective by virtue
of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent previously
given shall automatically and without further action by any Holder be canceled and of no further effect.

 

Upon the written request of the Company, and upon
the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.05, the Trustee shall
join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated
to, enter into such supplemental indenture.

 

Holders do not need under this Section 10.02
to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof.
After any such supplemental indenture becomes effective, the Company shall send to the Holders a notice briefly describing such supplemental
indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity
of the supplemental indenture.

 

Section 10.03.       
Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of
this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights,
limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter
be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

 

Section 10.04.        Notation
on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of
this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform,
in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental
indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated upon receipt of a Company
Order, by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in
exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

Section 10.05.       
Trustee to Sign Amendments. The Trustee shall sign any amendment, supplement or waiver authorized pursuant hereto
if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any
amendment, supplement or waiver, the Trustee shall receive and shall be fully protected in relying upon, in addition to the documents
required by Section 17.05, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended
or supplemental indenture is authorized or permitted by this indenture.

Section 11.01.        Company May Consolidate, Merge, etc., on Certain Terms. Subject to the provisions of Section 11.02, the Company
shall not amalgamate or consolidate with, merge with or into, or convey, transfer or lease all or substantially all of its properties
and assets to another Person, unless:

 

(a)             
the Company shall be the surviving Person or the resulting, surviving or transferee Person (the “Successor Entity”),
and if not the Company, shall be an entity organized and existing under the laws of the United States of America, any State thereof or
the District of Columbia, and the Successor Entity (if not the Company) shall expressly assume, by supplemental indenture, executed and
delivered to the Trustee, in form satisfactory to the Trustee, all of the obligations of the Company under the Notes and the Indenture
as applicable to the Notes (and, if such Successor Entity is not a corporation, then such Successor Entity will cause a corporate co-issuer
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia to become a co-obligor
on the Notes); and

 

(b)             
immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under
the Indenture.

 

Section 11.02.        Successor
Entity to Be Substituted. In case of any such amalgamation, consolidation, merger, conveyance, transfer or lease and upon the
assumption by the Successor Entity, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the due and punctual payment of the principal of (including any Fundamental Change Purchase Price), the Redemption Price

punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance
of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Entity (if not the Company) shall
succeed to and, shall be substituted for the Company and may exercise every right and power of, the Company under the Indenture, with
the same effect as if it had been named herein as the party of the first part. Such Successor Entity, if a successor to the Company,
thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable
hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor
Entity instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered
by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Entity thereafter shall cause to
be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such
Notes had been issued at the date of the execution hereof. In the event of any such amalgamation, consolidation, merger, conveyance or
transfer (but not in the case of a lease), the Person named as the “Company” in the first paragraph of this Indenture (or
any successor that shall thereafter have become such in the manner prescribed in this Article 11) may be dissolved, wound up and
liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and
maker of the Notes and from its obligations under this Indenture and the Notes.

 

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

 

Section 11.03.        Opinion of Counsel to Be Given to Trustee. In the case of any such amalgamation, merger, consolidation, conveyance,
transfer or lease, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel stating that any such amalgamation,
consolidation, merger, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection
with such transaction, such supplemental indenture, complies with the provisions of this Article 11.

CONVERSION OF NOTES

 

Section 14.01.       
Right to Convert. (a) Subject to and upon compliance with the
provisions of the Indenture, each Holder shall have the right, at such Holder’s option, to convert its Notes, or any portion of
its Notes such that the principal amount that remains outstanding of each Note that is not converted in full equals $1,000 or an integral
multiple of $1,000 in excess thereof, for the Settlement Amount determined in accordance with Section 14.04(a) hereof, prior to
the Close of Business on the Business Day immediately preceding the Maturity Date.

 

(b)             
(1) If the Company calls any or all Notes for Optional Redemption pursuant to Article 16 hereof prior to the Close of Business
on the Business Day immediately preceding the Maturity Date, then a Holder may surrender all or any portion of its Notes for conversion
at any time prior to the Close of Business on the Scheduled Trading Day prior to the relevant Redemption Date. After that time, the right
to convert on account of the Company’s delivery of a Redemption Notice shall expire, unless the Company defaults in the payment
of the Redemption Price, in which case a Holder of Notes may convert its Notes until the Redemption Price has been paid or duly provided
for.

 

(2)            
If, prior to the Close of Business on the Business Day immediately preceding the Maturity Date, the Company elects to:

 

(A)         
issue to all or substantially all holders of shares of the Common Stock any rights, options or warrants entitling them for a period
of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock
at a price per share that is less than the average of the Last Reported Sale Prices per share of the Common Stock for the 10 consecutive
Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance (taking into
account any consideration received by the Company as described in Section 14.05(b)); or

 

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

 

then, in either case, the Company must notify the Holders
at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice,
Holders may surrender all or any portion of their Notes for conversion at any time until the earlier of 5:00 p.m., New York City time,
on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and the Company’s announcement
that such issuance or distribution will not take place. Holders of the Notes will not, however, have the right to convert pursuant to
this subsection (b)(2) if they participate, at the same time and upon the same terms, as holders of shares of the Common Stock in any
of the transactions described above without having to convert their Notes as if they held a number of shares of the Common Stock equal
to the applicable Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance or distribution
multiplied by the principal amount (expressed in thousands) of Notes held by such holder on the Ex-Dividend Date for such issuance or
distribution.

 

(3)             If
(A) a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the Close of Business on the Business Day immediately
preceding the Maturity Date, regardless of whether a Holder has the right to require the Company to purchase the Notes in accordance
with the provisions of Article 15, or (B) the Company is a party to a consolidation, merger, binding share conversion, or transfer
or lease of all or substantially all of its assets (other than a merger effected solely to change the Company’s jurisdiction
of incorporation that does not otherwise constitute a Fundamental Change or a Make-Whole Fundamental Change), in each case, pursuant
to which the shares of the Common Stock would be converted into cash, securities or other assets, all or any portion of a
Holder’s Notes may be surrendered for conversion at any time from or after the effective date of the transaction or event
until 35 Trading Days after such effective date or, if such transaction or event also constitutes a Fundamental Change, until the
related Fundamental Change Purchase Date. The Company will notify the Holders, the Trustee and the Conversion Agent (if other than
the Trustee) no later than the effective date of such transaction or event.

 

    30

     

    

 

(c)              Notwithstanding any other provision of the Notes or this Indenture, no Holder of Notes will be entitled to receive shares of the
Common Stock following conversion of such Notes to the extent that receipt of such shares of the Common Stock would cause such Holder
to exceed the ownership limits contained in the Company’s charter, unless such Holder has been exempted from such limit in the Board
of Directors’ sole discretion in accordance with the Company’s charter.

 

(d)             
If any delivery of shares of the Common Stock owed to a Holder upon conversion of Notes is not made, in whole or in part, as a
result of the limitations described in Section 14.01(c), the Company’s obligation to make such delivery shall not be extinguished
and the Company shall deliver such shares as promptly as practicable after any such converting Holder gives notice to the Company that
such delivery would not result in a violation of the ownership limit contained in the Company’s charter.

 

(e)             
Neither the Trustee nor the Conversion Agent shall be responsible for monitoring compliance with Section 14.01(c) or (d)
and, absent written direction from the Company to the contrary, may assume that any conversion complies with the limitations set forth
therein.

 

Section 14.02.       
Exchange in Lieu of Conversion. (a) When a Holder surrenders its Notes for conversion, the Company may, at its election,
cause such Notes to be delivered, on or prior to the Business Day immediately following the relevant Conversion Date, to one or more financial
institutions designated by the Company (each, a “Designated Institution”) for exchange in lieu of conversion (an “Exchange
Election”). In order to accept any Notes surrendered for conversion for exchange in lieu of conversion, the Designated Institution(s)
must agree to timely pay or deliver, as the case may be, in exchange for such Notes, cash, shares of the Common Stock or a combination
of cash and shares of the Common Stock, at the Company’s election, that would otherwise be due upon conversion as described in Section
14.03 and Section 14.04 below or such other amount agreed to by the Holder and the Designated Institution(s) (the “Conversion
Consideration”). If the Company makes an Exchange Election, the Company shall, by the Close of Business on the Business Day
following the relevant Conversion Date, notify in writing the Trustee, the Conversion Agent (if other than the Trustee) and the Holder
surrendering Notes for conversion that it has made such Exchange Election, and the Company shall notify the Designated Institution(s)
of the relevant deadline for delivery of the Conversion Consideration and the type of Conversion Consideration to be paid and/or delivered,
as the case may be. The Conversion Agent shall be entitled to conclusively rely upon the Company’s instruction in connection with
effecting any Exchange Election and shall have no liability for such Exchange Election outside of its control.

 

(b)             
Any Notes delivered to the Designated Institution(s) shall remain outstanding, subject to the applicable procedures of the Depositary.
If the Designated Institution(s) agree(s) to accept any Notes for exchange but does not timely pay and/or deliver, as the case may be,
the related Conversion Consideration, or if such Designated Institution does not accept such Notes for exchange, the Company shall pay
or deliver, as the case may be, the relevant Conversion Consideration in accordance with the provisions of Section 14.03 and Section
14.04 as if the Company had not made the Exchange Election.

 

(c)             
For the avoidance of doubt, in no event will the Company’s designation of any Designated Institution(s) pursuant to this
Section 14.03 require such Designated Institution(s) to accept any Notes for exchange (unless such Designated Institution has separately
made an agreement with the Company). The Company may, but will not be obligated to, enter into a separate agreement with any Designated
Institution that would compensate it for any such transaction.

 

Section 14.03.       
Conversion Procedure.

 

(a)             
Settlement of Accrued Interest and Deemed Payment of Principal. If a Holder converts a Note, the Company will not adjust
the Conversion Rate to account for any accrued and unpaid interest on such Note and the Company’s delivery of cash and the number
of shares of the Common Stock into which a Note is convertible, together with any cash payment for any fractional shares of the Common
Stock, will be deemed to satisfy and discharge in full 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; provided, however, that if a Holder converts a Note after a Regular
Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will still be obligated to pay the
interest due on such Interest Payment Date to the Holder of such Note on such Regular Record Date (provided the Holder makes the interest
payment upon conversion if so required by Section 14.03(h)).

 

As a result, except as otherwise provided in
the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect to a converted Note will be deemed
to be paid in full rather than canceled, extinguished or forfeited. Upon a conversion of Notes into cash, and, if applicable, shares
of the Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion.

 

    31

     

    

 

(b)             
Notices. Upon receipt of a Notice of Conversion (as contemplated below), the Conversion Agent shall promptly notify the
Company.

 

(c)              
Settlement Location. Each Note shall be convertible at the office of the Conversion Agent and, if applicable, in accordance
with the Applicable Procedures.

 

(d)             
Notice. To exercise the conversion privilege with respect to a beneficial interest in a Global Note, the Holder must complete
the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, furnish appropriate
endorsements and transfer documents if required by the Company or the Conversion Agent, and pay the funds, if any, required by Section
14.03(h) and any taxes or duties if required pursuant to Section 14.03(i), and the Conversion Agent must be informed of the
conversion in accordance with the customary practice of the Depositary.

 

To exercise the conversion privilege with respect
to any Physical Notes, the Holder of such Physical Notes shall:

 

(1)            
complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “Notice
of Conversion”) or a facsimile of the Notice of Conversion;

 

(2)            
deliver the Notice of Conversion, which is irrevocable, and the Note to the Conversion Agent;

 

(3)            
if required, furnish appropriate endorsements and transfer documents;

 

(4)            
if required, make any payment required under Section 14.03(h); and

 

(5)            
if required, pay all transfer or similar taxes as set forth in Section 14.03(i).

 

If, upon conversion of a Note, any shares of the
Common Stock are to be issued to a person other than the Holder of such Note, the related Notice of Conversion shall include such other
person’s name and address.

 

If the Company calls the Notes for redemption pursuant
to Article 16, Holders may convert their Notes at any time prior to the Close of Business on the Scheduled Trading Day immediately
preceding the Redemption Date. After that time, Holders will no longer have the right to convert their Notes on account of the Company’s
delivery of the relevant Redemption Notice, unless the Company defaults in the payment of the Redemption Price, in which case a Holder
of the Notes may convert its Notes until the Redemption Price has been paid or duly provided for.

 

If a Note is subject to a Fundamental Change Purchase
Notice, such Note may not be converted unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 15.04
prior to the relevant Fundamental Change Expiration Time.

 

For any Note, the first Business Day on which the
Holder of such Note satisfies all of the applicable requirements set forth above with respect to such Note and on which conversion of
such Note is not otherwise prohibited under this Indenture shall be the “Conversion Date” with respect to such Note.

 

Each conversion shall be deemed to have been effected
as to any such Notes (or portion thereof) surrendered for conversion at the Close of Business on the applicable Conversion Date, and the
Person in whose name the certificate for any shares of the Common Stock delivered upon conversion is registered shall be treated as a
stockholder of record as of the Close of Business on the last Trading Day of the relevant Observation Period. In no event will a Holder
be entitled to receive any dividend or other distribution with respect to any shares of the Common Stock issued on conversion of such
Holder’s Notes if the last Trading Day of the relevant Observation Period is after the Record Date for such dividend or distribution.

 

Subject to the provisions of Section 14.07(b)
and Section 14.08(a), the Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of its Conversion
Obligation no later than the second Trading Day immediately following the last Trading Day of the relevant Observation Period.

 

If any shares of the Common Stock are due to exchanging
Holders, the Company shall issue or cause to be issued, and the Company shall deliver to such Holder, or such Holder’s nominee or
nominees, certificates or a book-entry transfer through the Depositary, as the case may be, for the full number of shares of the Common
Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

 

(e)              
Endorsement. Any Notes surrendered for conversion shall, unless shares of the Common Stock issuable on conversion are to
be issued in the same name as the registration of such Notes, be duly endorsed by, or be accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the Holder or its duly authorized attorney.

 

    32

     

    

 

(f)               Physical Notes. If any Notes in a denomination greater than $1,000 shall be surrendered for partial conversion, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of the Notes so surrendered, without charge, new Notes in
authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Notes.

 

(g)              Global
Notes. Upon the conversion of a beneficial interest in Global Notes, the Conversion Agent shall make a notation in its records as
to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes
effected through any Conversion Agent other than the Trustee.

 

(h)             
Interest Due Upon Conversion. If a Holder converts a Note after the Close of Business on a Regular Record Date but prior
to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Note with
an amount of cash equal to the amount of interest that will be payable on such Note on the corresponding Interest Payment Date (regardless
of whether the exchanging Holder was the Holder of record on the corresponding Regular Record Date); provided, however, that a Holder
need not make such payment (1) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; (2) if
the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment
Date; (3) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding
Interest Payment Date; or (4) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect
to such Note. Therefore, for the avoidance of doubt, all record Holders of Notes on the Regular Record Date immediately preceding the
Maturity Date, any Redemption Date, any Issuer Conversion Date or Fundamental Change Purchase Date described in the preceding sentence
will receive the full interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their
Notes have been converted following such Regular Record Date.

 

(i)             Taxes Due upon Conversion. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or
transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests
that any shares be issued in a name other than the Holder’s name, in which case the Holder will pay that tax.

 

Section 14.04.       
Settlement Upon Conversion.

 

(a)             
Subject to this Section 14.04, Section 14.07 and Section 14.08, upon conversion of any Note, the Company shall
pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash
(“Cash Settlement”), shares of the Common Stock, together with cash, if applicable, in lieu of delivering any fractional
share of the Common Stock in accordance with subsection (j) of this Section 14.04 (“Physical Settlement”) or
a combination of cash and shares of the Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of
the Common Stock in accordance with subsection (j) of this Section 14.04 (“Combination Settlement”), at its
election, as set forth in this Section 14.04.

 

(1)            
All conversions for which the relevant Conversion Date occurs at any time prior to the Close of Business on the Business Day immediately
preceding the Maturity Date, and all conversions for which the relevant Conversion Date occurs on or after the Company’s issuance
of a Redemption Notice or an Issuer Conversion Notice with respect to the Notes and prior to the related Redemption Date or Issuer Conversion
Date, as the case may be, shall be settled using the same Settlement Method.

 

(2)            
Except for any conversions for which the relevant Conversion Date occurs on or after the Company’s issuance of a Redemption
Notice or Issuer Conversion Notice and prior to the related Redemption Date or Issuer Conversion Date, as the case may be, the Company
shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation
to use the same Settlement Method with respect to conversions with different Conversion Dates.

 

(3)             If,
in respect of any Conversion Date (or one of the periods described in the third immediately succeeding set of parentheses, as the
case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method
in respect of such Conversion Date (or such period, as the case may be), the Company shall deliver such Settlement Notice to
converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than the Close of Business on the
Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion
Date occurs after the date of issuance of a Redemption Notice or an Issuer Conversion Notice with respect to the Notes and prior to
the related Redemption Date or Issuer Conversion Date, as the case may be, in the Redemption Notice or Issuer Conversion Notice). If
the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company
shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected
Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes
shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of
Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of
Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does
not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount
per $1,000 principal amount of Notes shall be deemed to be $1,000.

 

    33

     

    

 

(4)            
The cash, shares of the Common Stock or combination of cash and shares of the Common Stock in respect of any conversion of Notes
(the “Settlement Amount”) shall be computed as follows:

 

(A)         
if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall
deliver to the converting Holder in respect of each $1,000 principal amount of Notes being converted a number of shares of the Common
Stock equal to the Conversion Rate in effect on the Conversion Date;

 

(B)         
if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall
pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of
the Daily Conversion Values for each of the 40 consecutive Trading Days during the related Observation Period; and

 

(C)         
if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination
Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted,
a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive Trading Days during the related Observation
Period.

 

(5)            
The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company
promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily
Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of the Common Stock,
the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily
Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of the Common Stock. The
Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

 

(b)             
Subject to Section 14.04(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder
shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds
equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.04(h)
and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth
in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent
and state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder
wishes the certificate or certificates for any shares of the Common Stock to be delivered upon settlement of the Conversion Obligation
to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer
documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if
required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section
14.04(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article
14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof
if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn
such Fundamental Change Repurchase Notice in accordance with Section 15.03. If more than one Note shall be surrendered for conversion
at any one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

 

(c)             
A Note shall be deemed to have been converted immediately prior to the Close of Business on the Conversion Date. If the Company
elects Physical Settlement with respect to any conversion of the Notes, the Company shall deliver the consideration due in respect of
conversion on the second Business Day immediately following the relevant Conversion Date (provided that, with respect to any conversion
following the Regular Record Date immediately preceding the Maturity Date where Physical Settlement is applicable, the Company shall settle
any such conversion on the Maturity Date). If the Company elects (or is deemed to have elected) Cash Settlement or Combination Settlement
with respect to any conversion of Notes, except as set forth in Section 14.07(b) and Section 14.08(a), the Company shall
pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the second Business Day immediately
following the last Trading Day of the Observation Period. If any shares of the Common Stock are due to a converting Holder, the Company
shall issue or cause to be issued, and deliver (if applicable) to the Conversion Agent or to such Holder, or such Holder’s nominee
or nominees, the full number of shares of the Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary,
in satisfaction of the Company’s Conversion Obligation.

 

(d)              
In case any Physical Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate
and deliver to or upon the written order of the Holder of the Physical Note so surrendered a new Physical Note or Notes in
authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Physical Note, without
payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient
to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be
imposed in connection therewith as a result of the name of the Holder of the new Physical Notes issued upon such conversion being
different from the name of the Holder of the old Physical Notes surrendered for such conversion.

 

    34

     

    

 

(e)             
If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on
the issue of any shares of the Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued
in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver
the certificates representing the shares of the Common Stock being issued in a name other than the Holder’s name until the Trustee
receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

 

(f)              
Except as provided in Section 14.05, no adjustment shall be made for dividends on any shares of Common Stock issued upon
the conversion of any Note as provided in this Article 14.

 

(g)             
Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make
a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in
writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

 

(h)             
Upon conversion, other than upon exercise of the Issuer Conversion Option, a Holder shall not receive any separate cash payment
for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall
be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not
including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion
Date, other than a conversion upon exercise of the Issuer Conversion Option, shall be deemed to be paid in full rather than cancelled,
extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of the Common Stock, accrued and unpaid interest
will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after
the Close of Business on a Regular Record Date, Holders of such Notes as of the Close of Business on such Regular Record Date will receive
the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered
for conversion during the period from the Close of Business on any Regular Record Date to the open of business on the immediately following
Interest Payment Date, however, must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided
that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Redemption Date or Issuer Conversion Date that is after a Regular Record Date and on or prior to the
Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Repurchase
Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment
Date; or (4) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note.
Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date shall
receive the full interest payment due on the Maturity Date in cash regardless of whether their Notes have been converted following such
Regular Record Date.

 

(i)              
The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record
as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical
Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation
by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered
for conversion.

 

(j)              
The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu
of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in
the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case of
Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number
of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the
relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

 

Section 14.05.       
Adjustment of Conversion Rate. The Conversion Rate will be adjusted as described in this Section 14.05, except
that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of (x) a share split
or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the shares of the Common
Stock and as a result of holding the Notes, in any of the transactions described below without having to convert their Notes, as if they
held a number of shares of the Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in
thousands) of Notes held by such Holder.

 

    35

     

    

 

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

 

 

where,

 

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

 

Any adjustment made under this Section 14.05(a)
shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately
after the Open of Business on the effective date for such share split or share combination, as applicable. If any dividend or distribution
of the type described in this Section 14.05(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted,
effective as of the date the Board of Directors determines not to pay such dividend or distribution to the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared.

 

(b)             
If the Company issues to all or substantially all holders of the shares of the Common Stock any rights, options or warrants (other
than rights issued pursuant to a stockholder rights plan prior to separation of the relevant rights) entitling them, for a period of not
more than 45 calendar days after the date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share
that is less than the average of the Last Reported Sale Prices per share of the Common Stock for the 10 consecutive Trading Day-period
ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate will be
increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate
    in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
	 	 	 
	CR1	=	the Conversion Rate in effect
    immediately after the Open of Business on such Ex-Dividend Date;
	 	 	 
	OS0	=	the number of shares of Common
    Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;

 

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

 

	Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the
average of the Last Reported Sale Prices per share of the Common Stock over the 10 consecutive Trading Day-period ending on, and including,
the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 

Any increase made under this Section
14.05(b) will be made successively whenever any such rights, options or warrants are issued and shall become effective
immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or
warrants are not exercised prior to their expiration or shares of the Common Stock are not delivered upon the expiration of such
rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the
increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of
shares of the Common Stock actually delivered. If such rights, options or warrants are not so issued, or if such rights, options or
warrants are not exercised prior to their expiration, the Conversion Rate shall be decreased to be the Conversion Rate that would
then be in effect if such Record Date for such issuance had not occurred.

 

    36

     

    

 

For purposes of this Section 14.05(b) and
Section 14.01(b)(2)(A), in determining whether any rights, options or warrants entitle the holders of the shares of the Common
Stock to subscribe for or purchase shares of the Common Stock at a price per share less than such average of the Last Reported Sale Prices
per share of the Common Stock for the 10 consecutive Trading Day-period ending on the Trading Day immediately preceding the date of announcement
for such issuance, and in determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account
any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof,
the value of such consideration, if other than cash, to be determined by the Board of Directors.

 

(c)             
If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company
or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the shares of
the Common Stock, excluding: (1) dividends or distributions, rights, options or warrants as to which an adjustment was effected pursuant
to Section 14.05(a) or Section 14.05(b); (2) dividends or distributions paid exclusively in cash as to which an adjustment
was effected pursuant to Section 14.05(d); and (3) Spin-Offs as to which the provisions set forth below in this Section 14.05(c)
shall apply; then the Conversion Rate shall be increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate
    in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect
    immediately after the Open of Business on such Ex-Dividend Date;
	 	 	 
	SP0	=	the average of the Last Reported
    Sale Prices per share of the Common Stock over the 10 consecutive Trading Day-period ending on, and including, the Trading Day immediately
    preceding the Ex-Dividend Date for such distribution;

 

	FMV	=	and the fair market value
                                            (as determined by the Board of Directors in good faith) of the shares of the Company’s
                                            Capital Stock, evidences of the Company’s indebtedness, other assets, or property of
                                            the Company or rights, options or warrants to acquire the Company’s Capital Stock or
                                            other securities distributed with respect to each outstanding share of Common Stock on the
                                            Ex-Dividend Date for such distribution.

 

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

 

Any increase made under the portion of this Section
14.05(c) above will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such
distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared.

 

With respect to an adjustment pursuant to this
Section 14.05(c) where there has been a payment of a dividend or other distribution on the shares of the Common Stock of shares
of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary of the Company or other business unit
of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation
of the distribution) on a United States national securities exchange (a “Spin-Off”), the Conversion Rate will be increased
based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate
    in effect immediately prior to the end of the Valuation Period (as defined below);
	 	 	 
	CR1	=	the Conversion Rate in effect
    immediately after the end of the Valuation Period;

 

	FMV0	=	the average of the
    Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of shares of the Common Stock applicable
    to one share of the Common Stock over the first 10 consecutive Trading Day-period after, and including, the Ex-Dividend Date of the
    Spin-Off (the “Valuation Period”);
	 	 	 
	MP0	=	and the average of the Last
    Reported Sale Prices per share of the Common Stock over the Valuation Period.

 

    37

     

    

 

The increase in the Conversion Rate made under
the preceding paragraph of this Section 14.05(c) will be determined as of the Close of Business on the last Trading Day of the
Valuation Period, but will be given effect immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off; provided that
in respect of any conversion of Notes, for any Trading Day that falls within the relevant Observation Period for such conversion and within
the Valuation Period, references within this Section 14.05(c) to 10 consecutive Trading Days shall be deemed replaced with such
lesser number of Trading Days as have elapsed from, and including the Ex-Dividend Date for such Spin-Off to, and including, such Trading
Day in determining the applicable Conversion Rate as of such Trading Day. If any dividend or distribution that constitutes a Spin-Off
is declared but not so paid or made, the Conversion Rate shall be immediately decreased, effective as of the date the Board of Directors
determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared or announced. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease
in the Conversion Rate, no adjustment to the Conversion Rate will be made (other than with respect to the Company’s right to readjust
the Conversion Rate).

 

For purposes of the second adjustment set forth
in this Section 14.05(c), (i) the Last Reported Sale Price of any Capital Stock or similar equity interest shall be calculated
in a manner analogous to that used to calculate the Last Reported Sale Price per share of the Common Stock in the definition of “Last
Reported Sale Price” set forth in Section 1.01, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading
Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner
analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption
Event has occurred) for the shares of the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period
will be determined based on whether a day is a Trading Day for both the shares of the Common Stock and such Capital Stock or similar equity
interest.

 

Subject to Section 14.11, for the purposes
of this Section 14.05(c), rights, options or warrants distributed by the Company to all holders of shares of the Common Stock entitling
them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which
rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed
to be transferred with such shares of the Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances
of shares of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.05(c), (and no adjustment
to the Conversion Rate under this Section 14.05(c) will be required) until the occurrence of the earliest Trigger Event, whereupon
such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion
Rate shall be made under this Section 14.05(c). If any such right, option or warrant, distributed prior to the Issue Date is subject
to events, upon the occurrence of which such right, option or warrant becomes exercisable to purchase different securities, evidences
of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution
and Ex-Dividend Date of such deemed distribution (in which case the original right, option or warrant shall be deemed to terminate and
expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights,
options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was
counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.05(c)
was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by
any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or
warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution
or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received
by holders of shares of the Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such
rights, options or warrants), made to all holders of shares of the Common Stock as of the date of such redemption or purchase, and (2)
in the case of such rights, options or warrants which shall have expired or been terminated without exercise by any holders thereof, the
Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

 

For purposes of Section 14.05(a), Section
14.05(b) and this Section 14.05(c), if any dividend or distribution to which this Section 14.05(c) applies includes
one or both of:

 

(A)         
a dividend or distribution of shares of the Common Stock to which Section 14.05(a) also applies (the “Clause A
Distribution”); or

 

(B)          a
dividend or distribution of rights, options or warrants to which Section 14.05(b) also applies (the “Clause B
Distribution”), then (i) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 14.05(c) applies (the “Clause C
Distribution”) and any Conversion Rate adjustment required to be made under this Section 14.05(c) with respect to
such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C
Distribution and any Conversion Rate adjustment required by Section 14.05(b) with respect thereto shall then be made, except
that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause B Distribution and the Clause A
Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (B) any shares of the Common Stock
included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to
the Open of Business on such Ex-Dividend Date” within the meaning of Section 14.05(b), and (iii) the Clause A
Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may
be, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B
Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution, and (B) any shares of the Common
Stock included in the Clause A distribution shall not be deemed to be “outstanding immediately prior to the Open of Business
on such Ex-Dividend Date or such effective date” within the meaning of Section 14.05(a).

 

    38

     

    

 

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

 

 

where,

 

	CR0	=	the Conversion Rate
    in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect
    immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
	 	 	 
	SP0	=	the Last Reported Sale Price
    per share of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

 

	C	=	the amount in cash per share that the Company distributes to holders of the shares of Common Stock.

 

Any increase made pursuant to this Section 14.05(d)
shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If such dividend
or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not
to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had
not been declared.

 

If “C” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder shall receive, for
each $1,000 principal amount of Notes it holds, at the same time and upon the same terms as holders of the shares of the Common Stock,
the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion
Rate in effect on the Record Date for such cash dividend or distribution.

 

(e)              
If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the shares of the
Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds
the Last Reported Sale Price per share of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges
may be made pursuant to such tender or exchange offer (the “Offer Expiration Date”), the Conversion Rate shall be adjusted
based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate
    in effect immediately prior to the Close of Business on the Offer Expiration Date;
	 	 	 
	CR0	=	the Conversion Rate in effect
    immediately after the Close of Business on the Offer Expiration Date;

 

	AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common
Stock purchased in such tender offer or exchange offer;

 

	OS0	=	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);

 

    39

     

    

 

	OS1	=	the number of shares
    of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after
    giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and
	 	 	 
	SP1	=	the average of the Last Reported
    Sale Prices per share of Common Stock over the 10 consecutive Trading Day-period commencing on, and including, the Trading Day next
    succeeding the Offer Expiration Date.

 

The adjustment to the applicable Conversion Rate
under the preceding paragraph of this Section 14.05(e) will be given effect at the Open of Business on the Trading Day next succeeding
the Offer Expiration Date. For purposes of determining the applicable Conversion Rate in respect of any conversion of Notes, for any Trading
Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including,
the Trading Day next succeeding the Offer Expiration Date, references within this Section 14.05(e) to “10” or “10th”
shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Offer Expiration Date and such Trading Day
in determining the Conversion Rate as of such Trading Day.

 

(f)              
Except as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any
securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such
convertible or exchangeable securities.

 

(g)             
Notwithstanding anything to the contrary in this Article 14, the Conversion Rate shall not be adjusted:

 

(i)           
on account of stock repurchases that are not tender offers referred to in Section 14.05(e), including structured or derivative
transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors or otherwise;

 

(ii)           
upon the issuance of any shares of the 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 the Common Stock
under any plan;

 

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

 

(iv)         
upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible
security not described in the preceding clause (iii) and outstanding as of the date the Notes were first issued;

 

(v)          
for a change in the par value of the shares of the Common Stock;

 

(vi)         
for accrued and unpaid interest on the Notes, if any; or

 

(vii)        
for an event otherwise requiring an adjustment under this Indenture if such event is not consummated.

 

(h)             
All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest
one-ten thousandth (1/10,000th) of a share.

 

(i)              
For purposes of this Section 14.05, the number of shares of the Common Stock at any time outstanding shall not include shares
of the Common Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares
of the Common Stock held in the treasury of the Company or the Company, as the case may be, but shall include shares of the Common Stock
issuable in respect of scrip certificates issued in lieu of fractions of shares of the Common Stock.

 

(j)              
Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion
Agent if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief
statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’
Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry
that the last Conversion Rate of which it has knowledge is still in effect.

 

Section 14.06.       
Discretionary and Voluntary Adjustments.

 

(a)               Discretionary
Adjustments. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices over a
span of multiple days, the Company will make appropriate adjustments to account for any adjustment to the Conversion Rate that
becomes effective, or any event requiring an adjustment to the Conversion Rate where the Effective Date, Ex-Dividend Date, Record
Date or Offer Expiration Date of the event occurs, at any time during the period when such Last Reported Sale Prices are to be
calculated.

 

    40

     

    

 

(b)             
Voluntary Adjustments. To the extent permitted by applicable law and subject to the listing standards of the NYSE (if the
Company is then listed on the NYSE), the Company is permitted to increase the Conversion Rate of the Notes by any amount for a period
of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. Subject
to the listing standards of the NYSE (if the Company is then listed on the NYSE), the Company may also (but is not required to) increase
the Conversion Rate to avoid or diminish income tax to holders of shares of the Common Stock or rights to purchase shares of the Common
Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

 

Section 14.07.       
Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes, Notices
of Redemption or Issuer Conversion Notices. (a) If (i) the Effective Date of a Make-Whole Fundamental Change occurs prior to the
Maturity Date, (ii) the Company gives a Redemption Notice or (iii) the Company gives an Issuer Conversion Notice with respect to any or
all of the Notes as provided for in Article 16 and, in the case of clauses (i) and (ii), a Holder elects to convert its Notes in
connection with such Make-Whole Fundamental Change or during the related Redemption Period, as the case may be, the Company shall, under
certain circumstances, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of the
Common Stock (the “Additional Shares”), as described in this Section 14.07. A conversion of Notes shall be deemed
for these purposes to be “in connection with” a Make-Whole Fundamental Change if the relevant Conversion Date occurs during
the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on
the Business Day immediately prior to the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change
that would have been a Fundamental Change but for the exclusion in section (i) of clause (2) of the definition thereof, the 35th Trading
Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental
Change Period”). A conversion of Notes will be deemed for these purposes to be “in connection with” a Redemption
Notice or Issuer Conversion Notice, as the case may be, if the relevant Conversion Date occurs during the Redemption Period or prior to
the Issuer Conversion Date, respectively.

 

(b)             
Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, during a Redemption Period or prior
to an Issuer Conversion Date, the Company shall fulfill its Conversion Obligation in accordance with Section 14.03; provided, however,
that if, at the effective time of a Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change, the
Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the
Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Share Price for
the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate
(including any adjustment for Additional Shares), multiplied by such Share Price. In such event, the Conversion Obligation shall
be paid to Holders in cash on the Business Day following the Conversion Date. The Company shall notify the Holders of Notes of the Effective
Date of any Make-Whole Fundamental Change no later than such Effective Date.

 

(c)             
The number of Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Notes in
connection with a Make-Whole Fundamental Change, Redemption Notice or Issuer Conversion Notice shall be determined by reference to the
table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective or the date of the Redemption Notice
(in each case, the “Effective Date”) and the price (the “Share Price”) paid (or deemed to be paid)
per share of Common Stock in the Make-Whole Fundamental Change or determined with respect to the Redemption Notice, as the case may be.
If the holders of the shares of Common Stock receive in exchange for their shares of Common Stock only cash in a Make-Whole Fundamental
Change described in clause (2) of the definition of Fundamental Change, the Share Price will be the cash amount paid per share of Common
Stock. Otherwise, the Share Price will be the average of the Last Reported Sale Prices per share of Common Stock over the five Trading
Day-period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change or
the Redemption Notice, as the case may be. In the event a conversion in connection with a Redemption Notice would also be deemed to be
in connection with a Make-Whole Fundamental Change, a Holder of the Notes to be converted shall be entitled to a single increase to the
Conversion Rate with respect to the first to occur of (i) the applicable date of the Redemption Notice, (ii) the applicable date of the
Issuer Conversion Notice or (iii) the Effective Date of the applicable Make-Whole Fundamental Change, and the later event will be deemed
not to have occurred for purposes of such converted Notes.

 

(d)             
The Share Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate
of the Notes is otherwise required to be adjusted. The adjusted Share Prices shall equal the Share Prices applicable immediately prior
to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment
giving rise to the Share Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate is required to be adjusted
as set forth in Section 14.05.

 

    41

     

    

 

(e)          
 The following table sets forth the number of Additional Shares by which the Conversion Rate shall be increased per $1,000 principal
amount of Notes pursuant to this Section 14.07 for each Share Price and Effective Date set forth below:

 

	 	 	Share

The exact Share Prices and Effective Dates may
not be set forth in the table above, in which case:

 

(i)            
If the Share Price is between two Share Prices in the table or the Effective Date is between two Effective Dates in the table,
the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between
the number of Additional Shares set forth for the next higher and next lower Share Prices and the earlier and later Effective Dates, as
applicable, based on a 365-day year.

 

(ii)           
If the Share Price is greater than $13.00 per share (subject to adjustment in the same manner as the Share Prices set forth in
the column headings of the table above pursuant to Section 14.07(d) hereof), the Conversion Rate shall not be increased.

 

(iii)          
If the Share Price is less than $5.07 per share (subject to adjustments in the same manner as the Share Prices set forth in the
column headings of the table above pursuant to Section 14.07(d) hereof), the Conversion Rate shall not be increased.

 

Notwithstanding the foregoing, in no event will
the Conversion Rate be increased on account of a Make-Whole Fundamental Change to exceed 197.2386 shares of the Common Stock per $1,000
principal amount of Notes, subject to adjustments in the same manner as the Conversion Rate is required to be adjusted as set forth in
Section 14.05 hereof.

 

Section 14.08.       
Effect of Recapitalizations, Reclassifications and Changes of the Shares of the Common Stock.

 

(a)          
In the case of:

 

(i)            any
recapitalization, reclassification or change of the shares of Common Stock (other than a change in par value, or from par value to no
par value, or from no par value to par value, or as a result of a split, subdivision or combination for which an adjustment was made
pursuant to Section 14.05(a));

 

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

 

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

 

(iv)         
any statutory share exchange involving the Company;

 

in each case, as a result of which the shares of Common Stock
would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination
thereof) (any such event, a “Merger Event” and any such stock, other securities, other property or assets
(including cash or any combination thereof), “Reference Property”) then the Company or the successor or
purchasing entity, as the case may be, will execute with the Trustee a supplemental indenture providing that, at and after the
effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes based on a number of shares of
Common Stock equal to the applicable Conversion Rate will, without the consent of the Holders, be changed into a right to convert
each $1,000 principal amount of Notes based on a number of Units of Reference Property equal to the applicable Conversion Rate and,
prior to or at the effective time of such Merger Event, the Company or the successor or purchasing person, as the case may be, shall
execute with the Trustee a supplemental indenture providing for such change in the right to convert each $1,000 principal amount of
Notes. However, at and after the effective time of such Merger Event:

 

    42

     

    

 

(A)         
the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be,
in respect of its Conversion Obligation in accordance with Section 14.04; and

 

(B)         
(i) any amount payable in cash upon conversion of the Notes in accordance with Section 14.04 shall continue to be payable
in cash, (ii) any shares of the Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance
with Section 14.04 shall instead be deliverable in the type and amount of Reference Property that a holder of that number of shares
of the Common Stock would have received in such Merger Event and (iii) the Daily VWAP shall be calculated based on the value of a unit
of Reference Property that a holder of one share of the Common Stock would have received in such Merger Event; provided, however, that
if the holders of shares of the Common Stock receive only cash in such Merger Event, then for all conversions that occur after the effective
date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal aggregate amount of Notes shall be solely
cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant
to Section 14.07), multiplied by the Share Price in such Merger Event and (y) settlement will occur on the second Business Day
immediately following the Conversion Date.

 

If the Merger Event causes the shares of the Common
Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part
upon any form of shareholder election), the amount and type of Reference Property that a holder of shares of the Common Stock would have
been entitled to receive in such Merger Event (and for which the Notes will be convertible) will be deemed to be the weighted average
of the types and amounts of consideration actually received by the holders of shares of the Common Stock. The Company shall notify, in
writing, the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the weighted average as soon as practicable
after such determination is made.

 

The Company shall not become a party to any Merger
Event unless its terms are consistent with this Section 14.08. Such supplemental indenture described in the second immediately
preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article
14 in the judgment of the Board of Directors or the board of directors of the successor person. If, in the case of any such Merger
Event, the Reference Property receivable thereupon by a holder of shares of the Common Stock includes shares of stock, securities or other
property or assets (including cash or any combination thereof) of a person other than the successor or purchasing person, as the case
may be, in such Merger Event, then such supplemental indenture shall also be executed by such other person.

 

(b)             
The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such
Holder as it appears on the register of the Notes maintained by the Note Registrar, within 20 days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section
14.08 shall similarly apply to successive Merger Events.

 

(c)             
If the Notes become convertible into Reference Property, the Company shall notify the Trustee and issue a press release containing
the relevant information, disclose the relevant information in a Current Report on Form 8-K or post such information on the Company’s
website.

 

Section 14.09.       
Certain Covenants. (a) The Company covenants that all shares of the Common Stock that may be issued upon conversion
of Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and
shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder or due to a change
in registered owner).

 

(b)             
The Company covenants that, if any shares of the Common Stock to be provided for the purpose of conversion of Notes hereunder require
registration with or approval of any governmental authority under any federal or state law before such shares of the Common Stock may
be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be.

 

(c)             
The Company further covenants that it shall list or cause to have quoted any shares of the Common Stock to be issued upon conversion
of the Notes on each national securities exchange or over-the-counter or other domestic market on which the shares of the Common Stock
are then listed or quoted.

 

(d)             
To the extent necessary to satisfy its obligations under this Indenture, prior to issuing any shares of the Common Stock, the Company
will reserve out of its authorized but unissued shares of the Common Stock a sufficient number of shares of the Common Stock to permit
the conversion of the Notes.

 

    43

     

    

 

(e)             
 The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury,
sufficient shares of the Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion
(assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder).

 

Section 14.10.       
Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility
to any Holder of Notes to determine or calculate the Conversion Rate, to determine whether any facts exist which may require any adjustment
of the Conversion Rate, to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein
or in any supplemental indenture provided to be employed, in making the same or to make any determinations with respect to the ownership
limit in the Company’s charter. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity
or value (or the kind or amount) of any shares of the Common Stock or of any other securities or property that may at any time be issued
or delivered upon the conversion of any Notes; and the Trustee and the Conversion Agent make no representations with respect thereto.
Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares
of the Common Stock or stock certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion
or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 14. The rights, privileges,
protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent.

 

Section 14.11.       
Poison Pill. Whenever a Holder converts a Note, to the extent that the Company has a rights plan in effect, the Holder
converting such Note will receive, in addition to any shares of the Common Stock otherwise received in connection with such conversion,
the rights under the rights plan unless the rights have separated from the shares of the Common Stock, in which case, and only in such
case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of the shares of the
Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as described in Section
14.05(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

 

Section 14.12.       
Ownership Limit. Notwithstanding any other provision of the Notes, no Holders of Notes shall be entitled to convert
such Notes for shares of the Common Stock to the extent that receipt of such shares would cause such Holder (or any other Person) to exceed
the ownership limit contained in Section 2.9 of the Articles of Amendment and Restatement of the Charter dated as of November 8, 2013,
filed with the State Department of Assessments and Taxation of Maryland, as amended to the date hereof and as may be further amended,
supplemented or restated from time to time. The Trustee shall have no obligation for monitoring ownership limits upon the transfer or
exchange of Notes.

 

Section 14.13.       
Deferral of Adjustments. Notwithstanding anything to the contrary herein, the Company will not be required to adjust
the Conversion Rate unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any
such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and
provided, further, that any such adjustment of less than one percent that has not been made shall be made upon the occurrence of (i) the
Effective Date for any Make-Whole Fundamental Change; (ii) the Company’s giving of a Redemption Notice pursuant to Article 16;
and (iii) any conversion of Notes. In addition, the Company shall not account for such deferrals when determining whether any of the conditions
to conversion have been satisfied or what number of shares of the Common Stock a Holder would have held on a given day had it converted
its Notes.

 

Section 14.14.       
Limitation on Adjustments. Except as stated in Section 14.05, the Company will not adjust the Conversion Rate
for the issuance of shares of shares of the Common Stock or any securities convertible into or exchangeable for shares of shares of the
Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. If, however, the application
of the formulas in Sections 14.04(a) through (e) would result in a decrease in the Conversion Rate, then, except to the
extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse
share split, share combination or readjustment).

 

Section 14.15.       
Notice to Holders. The Notice to Holders Prior to Certain Actions. (a) The Company shall deliver notices of
the events specified below at the times specified below and containing the information specified below unless, in each case, (i) pursuant
to the Indenture, the Company is already required to deliver notice of such event containing at least the information specified below
at an earlier time or, (ii) the Company, at the time it is required to deliver a notice, does not have knowledge of all of the information
required to be included in such notice, in which case, the Company shall (A) deliver notice at such time containing only the information
that it has knowledge of at such time (if it has knowledge of any such information at such time), and (B) promptly upon obtaining knowledge
of any such information not already included in a notice delivered by the Company, deliver notice to each Holder containing such information.
In each case, the failure by the Company to give such notice, or any defect therein, shall not affect the legality or validity of such
event.

 

(i)             Issuances,
Distributions, and Dividends and Distributions. If the Company: (A) announces any issuance of any rights, options or warrants
that would require an adjustment in the Conversion Rate pursuant to Section 14.05(b); (B) authorizes any distribution that
would require an adjustment in the Conversion Rate pursuant to Section 14.05(c) hereof (including any separation of rights
from the shares of the Common Stock described in Section 14.11); or (C) announces any dividend or distribution that would
require an adjustment in the Conversion Rate pursuant to Section 14.05(d), then the Company shall deliver to the Holders, as
promptly as possible, but in any event at least 15 calendar days prior to the applicable Ex-Dividend Date, notice describing such
issuance, distribution, dividend or distribution, as the case may be, and stating the expected Ex-Dividend Date and Record Date for
such issuance, distribution, dividend or distribution, as the case may be. In addition, the Company shall deliver to the Holders
notice if the consideration included in such issuance, distribution, dividend or distribution, or the Ex-Dividend Date or Record
Date of such issuance, distribution, dividend or distribution, as the case may be, changes.

 

    44

     

    

 

(ii)          
Voluntary Increases. If the Company increases the Conversion Rate pursuant to Section 14.06(b), the Company shall
deliver notice to the Holders at least 15 calendar days prior to the date on which such increase will become effective, which notice shall
state the date on which such increased will become effective and the amount by which the Conversion Rate will be increased.

 

(iii)          
Dissolutions, Liquidations and Winding-Ups. If there is a voluntary or involuntary dissolution, liquidation or winding-up
of the Company, the Company shall deliver notice to the Holders as promptly as possible, but in any event at least 15 calendar days prior
to the earlier of (i) the date on which such dissolution, liquidation or winding-up, as the case may be, is expected to become effective
or occur, and (ii) the date as of which it is expected that holders of shares of the Common Stock of record shall be entitled to convert
their shares of the Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up, as the
case may be, which notice shall state the expected effective date and Record Date for such event, as applicable, and the amount and kind
of property that a holder of one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company
shall deliver an additional notice to holders, as promptly as practicable, whenever the expected effective date or Record Date, as applicable,
or the amount and kind of property that a holder of one share of the Common Stock is expected to be entitled to receive in such event,
changes.

 

(b)             
Notices After Certain Actions and Events. Whenever an adjustment to the Conversion Rate becomes effective pursuant to Section
14.05, 14.06 or 14.07 hereof, the Company will (i) file with the Trustee an Officers’ Certificate stating that
such adjustment has become effective, the Conversion Rate, and the manner in which the adjustment was computed and (ii) deliver notice
to the Holders stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure
to give any such notice, or any defect therein, shall not affect the validity of any such adjustment.

 

Section 14.16.       
Issuer Conversion.

 

(a)             
Issuer Conversion Date. On or after May 18, 2021, the Company may, at its option, elect to convert the principal amount
of the Notes in whole or in part (the “Issuer Conversion Option”) into cash, shares of the Common Stock or a combination
thereof, determined in accordance with Section 14.16(a), if the Last Reported Sale Price per share of the Common Stock has been
at least 130% of the Conversion Price then in effect for at least 20 Trading Days (whether or not consecutive) during any 30 consecutive
Trading Day-period (including the last Trading Day of such period) ending on, and including, the Trading Day immediately preceding the
date on which the Company provides Issuer Conversion Notice in accordance with Section 14.04(a). The Conversion Rate is subject
to adjustment in connection with the exercise of the Issuer Conversion Option, pursuant to Section 14.16(b), however the determination
of whether the Issuer Conversion Option is currently exercisable shall be made without giving effect to such adjustment.

 

(b)             
Issuer Conversion Notice; Selection of Notes. (i) In case the Company elects to exercise its Issuer Conversion Option to
convert all or, as the case may be, any part of the Notes pursuant to Section 14.16(a), it shall fix a date for conversion (each,
an “Issuer Conversion Date”) and it or, at its written request received by the Trustee not less than 20 Scheduled Trading
Days prior to the Issuer Conversion Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name
of and at the expense of the Company, shall give or cause to be given a notice of such Issuer Conversion (a “Issuer Conversion
Notice”) not less than 10 nor more than 15 Scheduled Trading Days prior to the Issuer Conversion Date mailed by first class
mail, postage prepaid or, in the case of any Global Notes, in accordance with the procedures of the Depositary for providing notices,
to each Holder of Notes so to be converted as a whole or in part at its last address as the same appears on the Note Register; provided,
however, that, if the Company shall give such notice, it shall also give written notice of the Issuer Conversion Date to the Trustee.
The Issuer Conversion Date must be a Business Day and may not fall on or after the date that is 180 calendar days immediately prior to
the Maturity Date. At the Company’s request, an Issuer Conversion Notice shall be given by the Trustee, in the name and at the expense
of the Company, with the notice information required under Section 14.16(b)(iii) delivered to the Trustee at least two Business
Days before such notice is to be given to the Holders (unless a shorter period shall be acceptable to the Trustee). The election of the
Company to convert any Notes pursuant to Section 14.16 shall be evidenced by a Board Resolution. The Company shall not less than
20 days prior to the Issuer Conversion Date fixed by the Company (unless a shorter notice period shall be satisfactory to the Trustee),
notify the Trustee in writing of such Issuer Conversion Date and of the principal amount of Notes to be converted. The Company shall furnish
the Trustee with an Officers’ Certificate evidencing compliance with the conditions to such conversion no later than the date the
Issuer Conversion Notice is given pursuant to this Section 14.16(b).

 

    45

     

    

 

(ii)           
 The Issuer Conversion Notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice. In any case, failure to give such Issuer Conversion Notice or any defect in the Issuer
Conversion Notice to the Holder of any Note designated for conversion as a whole or in part shall not affect the validity of the proceedings
for the conversion of any other Note.

 

(iii)          
Each Issuer Conversion Notice shall specify:

 

(A)         
the Issuer Conversion Date;

 

(B)         
the CUSIP or similar number or numbers of the Notes being converted, and that no representation is made as to the correctness or
accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes;

 

(C)         
that on and after the Issuer Conversion Date interest on the Notes to be converted will cease to accrue and the Notes will cease
to be outstanding;

 

(D)         
the name and address of each Paying Agent and Conversion Agent and the place or places where such Notes are to be surrendered;

 

(E)          
that the Notes subject to the Issuer Conversion Option may still be voluntarily converted pursuant to Section 14.07 on or
prior to the Close of Business on the Business Day immediately preceding the Issuer Conversion Date; and

 

(F)          
the Conversion Rate then in effect, the Settlement Method and the Specified Dollar Amount.

 

(c)           Notwithstanding the foregoing, the Company may only exercise its Issuer Conversion Option pursuant to Section 14.16(a) if,
as evidenced by an Officers’ Certificate, all of the conditions listed below (the “Equity Conditions”) are satisfied
on each day during the period (x) commencing on the Issuer Conversion Notice Date and (y) ending on the Issuer Conversion Date (the “Equity
Conditions Measuring Period”). The Equity Conditions are as follows:

 

(i)            
any shares of the Common Stock issuable upon conversion of the Notes and held by a non-Affiliate of the Company shall be eligible
for sale under applicable federal or state securities laws, either (x) without the need for registration under any applicable federal
or state securities laws or (y) by way of a re-sale registration statement filed by the Company and declared effective on or before the
date on which the Company provides an Issuer Conversion Notice to the Holders;

 

(ii)          
during the Equity Conditions Measuring Period, the Common Stock is listed or traded on the NYSE, the NYSE American, or Nasdaq (or
any of their respective successors) (each, an “Eligible Market”) and shall not have been suspended from trading on
such exchange or market (other than suspensions of not more than two Trading Days and occurring prior to the applicable date of determination
due to business announcements by the Company) nor shall delisting or suspension by such exchange or market been threatened or pending
either (A) in writing by such exchange or market or (B) by falling below the then effective minimum listing maintenance requirements of
such exchange or market;

 

(iii)         
any applicable shares of the Common Stock to be issued upon Issuer Conversion may be issued in full without violating the rules
or regulations of the NYSE or any other applicable Eligible Market on which the Common Stock delivered upon conversion is then listed
or trading; and

 

(iv)         
prior to the date of the applicable Issuer Conversion Notice Date , to the extent any Notes have been delivered to the Company
for conversion in accordance with the terms of the Notes, the Company shall have delivered and paid the number of shares of the Common
Stock and the amount of cash due upon conversion of such Notes to the Holders in accordance with Section 14.04, and no other Default
or Event of Default under the Indenture shall have occurred and be continuing.

 

(d)           Each
Holder of a Note, by the Holder’s acceptance thereof, agrees to take the following actions prior to the Issuer Conversion Date
if deemed necessary by the Company or, in the case of Notes represented by global notes, if required by DTC or any successor
Depositary: (i) surrendering the converted Note to the Conversion Agent, (ii) furnishing appropriate endorsements and transfer
documents if required by the Registrar or the Conversion Agent, (iii) if the Note is held in book-entry form, completing and
delivering to the Depositary appropriate instructions pursuant to the Depositary’s book-entry conversion programs, (iv) paying
the funds, if any, required by Section 6.03 and, if required, all taxes or duties, if any, and (v) any other action necessary
to effectuate the Issuer Conversion Option as may be reasonably requested by the Company. In the event that a Holder does not take
any of the actions set forth in the immediately preceding sentence prior to the Issuer Conversion Date, each Holder of a Note, by
the Holder’s acceptance thereof, authorizes and directs the Company to take any action on the Holder’s behalf to effect
the Issuer Conversion Option and appoints the Company such Holder’s attorney-in-fact for any and all such purposes. Such
appointment as attorney-in-fact is coupled with an interest and is irrevocable so long as any Note is outstanding. In order to
resell shares received upon conversion of the Notes under any re-sale registration statement filed in connection with any exercise
of the Issuer Conversion Option, Holders may be required to provide certain documentation as a selling stockholder. In the event a
Holder does not provide such required information, the Holder will not be eligible to resell its shares received upon conversion of
the Notes pursuant to such re-sale registration statement.

 

    46

     

    

 

(e)             
Upon conversion pursuant to an Issuer Conversion Option, interest on the Notes or portion of Notes so converted shall cease to
accrue and such Notes shall cease to be outstanding and cease to be entitled to any benefit under the Indenture, and the Holders thereof
shall have no right in respect of such Notes except the cash, shares of the Common Stock or combination thereof, as applicable, to which
they are entitled pursuant to Section 14.04(a) and this Section 14.16.

 

(f)               The Trustee and the Conversion Agent have no duty to verify whether the Equity Conditions have been satisfied and may conclusively
rely on the Officers’ Certificate delivered in connection therewith.

 

Section 14.17.       
Restrictions on Issuer Conversion. The Company may not convert any Notes pursuant to its Issuer Conversion Option
on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration
has not been rescinded, on or prior to the Issuer Conversion Date (except in the case of an acceleration resulting from a Default by the
Company in the payment of the Conversion Price with respect to such Notes).

REPURCHASE OF NOTES AT OPTION OF HOLDERS

 

Section 15.01.       
[Reserved.]

 

Section 15.02.       
Purchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs, then each Holder shall
have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Notes, or any portion
thereof such that the remaining principal amount of each Note that is not purchased in full equals $1,000 or an integral multiple of $1,000
in excess thereof, on a date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than
20 calendar days or more than 35 calendar days following the date on which the Company delivers the Fundamental Change Company Notice,
at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but excluding,
the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if the Company
purchases a Note on a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the Interest Payment Date
corresponding to such Regular Record Date, the Company shall instead pay such accrued and unpaid interest on such Note on the Interest
Payment Date to the Holder of record of such Note as of such Regular Record Date.

 

Purchases of Notes under this Section 15.02
shall be made, at the option of the Holder thereof, upon:

 

(i)            
if the Notes to be purchased are Physical Notes, delivery to the Paying Agent by the Holder of a duly completed notice (the “Fundamental
Change Purchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A and of
the Notes, duly endorsed for transfer, on or before the Close of Business on the Business Day immediately preceding the Fundamental Change
Purchase Date, subject to extensions to comply with applicable law (the “Fundamental Change Expiration Time”); and

 

(ii)           
if the Notes to be purchased are Global Notes, delivery of the Notes, by book-entry transfer, in compliance with the Applicable
Procedures and the satisfaction of any other requirements of the Depositary in connection with tendering beneficial interests in a Global
Note for purchase, by the Fundamental Change Expiration Time.

 

The Fundamental Change Purchase Notice in respect
of any Notes to be purchased shall state:

 

(i)            
if certificated, the certificate numbers of such Notes;

 

(ii)           
the portion of the principal amount of such Notes, which must be such that the principal amount that is not to be purchased of
each Note that is not to be purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof; and

 

(iii)          
that such Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Indenture.

 

Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 15.02 shall have
the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the Fundamental Change Expiration
Time by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 15.04.

 

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

 

    47

     

    

 

(b)             
 On or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the
Notes, the Trustee, the Conversion Agent and the Paying Agent (in the case of any Conversion Agent or Paying Agent other than the Trustee)
a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase
right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global
Notes, in accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change
Company Notice, the Company shall publish a press release containing this information or publish this information on the Company’s
website or through such other public medium as the Company may use at that time.

 

Each Fundamental Change Company Notice shall specify:

 

(i)            
the events causing the Fundamental Change;

 

(ii)           
the date of the Fundamental Change;

 

(iii)          
the last date on which a Holder of Notes may exercise the purchase right pursuant to this Article 15;

 

(iv)          
the Fundamental Change Purchase Price;

 

(v)           
the Fundamental Change Purchase Date;

 

(vi)          
the name and address of the Paying Agent and the Conversion Agent, if applicable;

 

(vii)         
the applicable Conversion Rate and any adjustments to the applicable Conversion Rate;

 

(viii)        
that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only
if the Holder withdraws the Fundamental Change Purchase Notice in accordance with this Indenture;

 

(ix)           
that the Holder shall have the right to withdraw any Notes surrendered for purchase prior to the Fundamental Change Expiration
Time; and

 

(x)            
the procedures that Holders must follow to require the Company to purchase their Notes.

 

No failure of the Company to give the foregoing
notices and no defect therein shall limit the purchase rights of the Holders of Notes or affect the validity of the proceedings for the
purchase of the Notes pursuant to this Section 15.02.

 

Notwithstanding anything herein to the contrary,
the Company shall not be required to deliver a Fundamental Change Company Notice or to purchase any Notes upon the occurrence of a Fundamental
Change if the Company has delivered a Redemption Notice for all of the Notes in accordance with Section 16.02, unless and until
there is a default in the payment of the Redemption Price.

 

(c)             
Notwithstanding the foregoing, there shall be no purchase of any Notes pursuant to this Section 15.02 if the principal amount
of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except
in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect
to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration
of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase
Price with respect to such Notes) and shall deem to be canceled any instructions for book-entry transfer of the Notes in compliance with
the procedures of the Depositary, in which case, upon such return or cancellation, as the case may be, the Fundamental Change Purchase
Notice with respect thereto shall be deemed to have been withdrawn.

 

Section 15.03.       
Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of a Fundamental Change Purchase Notice
specified in Section 15.02, the Holder of the Note in respect of which such Fundamental Change Purchase Notice was given shall
(unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 15.04) thereafter be entitled to receive
solely the Fundamental Change Purchase Price in cash with respect to such Note (and any previously accrued and unpaid interest on such
Note). Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later
of (x) the applicable Fundamental Change Purchase Date (provided the conditions in Section 15.02 have been satisfied) and (y) the
time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 15.02,
subject in each case to extensions to comply with applicable law.

 

Section 15.04.       
Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole
or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company
Notice at any time prior to the Fundamental Change Expiration Time, specifying:

 

    48

     

    

 

(a)              
 the principal amount of the Notes with respect to which such notice of withdrawal is being submitted;

 

(b)             
if Physical Notes have been issued, the certificate numbers of the withdrawn Notes; and

 

(c)             
the principal amount, if any, of each Note that remains subject to the Fundamental Change Purchase Notice, which must be such that
the principal amount not to be purchased equals $1,000 or an integral multiple of $1,000 in excess thereof;

 

provided, however, that if the Notes are Global Notes, the notice must
comply with Applicable Procedures.

 

The Paying Agent will promptly return to the respective
Holders thereof any Physical Notes with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the
provisions of this Section 15.04.

 

Section 15.05.       
Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m., New York City time, on the Fundamental Change
Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is
acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if
deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Notes or portions thereof that are
to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase
Price of the Notes that have been properly surrendered for purchase and not validly withdrawn and for which a Fundamental Change Purchase
Notice has been tendered and not withdrawn in accordance with this Indenture on the Fundamental Change Purchase Date, then as of such
Fundamental Change Purchase Date, (a) such Notes will cease to be outstanding and interest will cease to accrue thereon (whether or not
book-entry transfer of such Notes is made or whether or not such Notes have been delivered to the Paying Agent) and (b) all other rights
of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously
accrued and unpaid interest thereon upon delivery or book-entry transfer of such Notes).

 

Section 15.06.       
Notes Purchased in Whole or in Part. Any Note that is to be purchased, whether in whole or in part, shall be surrendered
at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Notes, due endorsement by,
or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s
attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such
Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount
equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased.

 

Section 15.07.       
Covenant to Comply with Applicable Laws Upon Purchase of Notes. In connection with any offer to purchase Notes under
Section 15.02, the Company shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender
offer and other applicable rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule
under the Exchange Act and (iii) otherwise comply with all U.S. federal and state securities laws applicable to the Company in connection
with such purchase offer, in each case, so as to permit the rights and obligations under Section 15.02 to be exercised in the time
and in the manner specified in Section 15.02. To the extent that the provisions of any securities laws or regulations enacted or
adopted after the date on which the Notes are first issued conflict with the provisions of this Indenture relating to the obligations
of the Company to purchase the Notes upon a Fundamental Change, the Company will comply with the applicable securities laws and regulations
and will not be deemed to have breached its obligations under such provisions of this Indenture by virtue of such conflict. In such event,
the Company shall deliver to the Trustee an Opinion of Counsel to the effect that the purchase of the Notes complies with applicable securities
laws and regulations.

 

Section 15.08.       
Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section
15.05 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase
as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return
any such excess to the Company.

postage prepaid or, in the case of any Global Notes, in accordance with the procedures of the Depositary for providing notices, to

however, that, if the Company shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The
Redemption Date must be a Business Day and may not fall on or after the date that is 180 calendar days immediately prior to the
Maturity Date. At the Company’s request, a Redemption Notice shall be given by the Trustee, in the name and at the expense of
the Company, with the notice information required under Section 16.02(c) delivered to the Trustee at least two Business Days
before such notice is to be given to the Holders (unless a shorter period shall be acceptable to the Trustee). The election of the

than 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice period shall be satisfactory to the
Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Notes to be redeemed. The Company
shall furnish the Trustee with an Officers’ Certificate evidencing compliance with the conditions to such redemption no later

or not the Holder receives such notice. In any case, failure to give such Redemption Notice or any defect in the Redemption Notice to
the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption
of any other Note.

 

(c)          
Each Redemption Notice shall specify:

 

(i)            
the Redemption Date;

Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued.

 

A Redemption Notice shall be irrevocable.

 

(d)             
If the Company redeems fewer than all of the outstanding Notes, the Notes to be redeemed shall be selected by the Trustee (in principal
amounts of $1,000 or integral multiples of $1,000 in excess thereof) by lot or pro rata basis, and in accordance with Applicable Procedures.
If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of the Note submitted
for conversion shall be deemed (so far as may be possible) to be the portion selected for redemption.

Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unredeemed
portion of the Note surrendered, without payment of any service charge.

 

Section 16.04.       
Restrictions on Redemption. The Company may not redeem any Notes on any date if the principal amount of the Notes
has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the

Section 17.03.        
Addresses for Notices, Demands, etc. Any notice or demand that by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders on the Company shall be in writing and shall be deemed to have been sufficiently
given or made, for all purposes if given or served by facsimile, electronic transmission or by being deposited postage prepaid by registered
or certified mail in a post office letter box or by overnight courier addressed (until another address is filed by the Company with the
Trustee), to 14185 Dallas Parkway, Suite 1100, Dallas, Texas 75254. Any notice, direction, request or demand hereunder to or upon the
Trustee shall be deemed to have been sufficiently given or made, for all purposes, if given or served by being deposited postage prepaid
by registered or certified mail in a post office letter box or by overnight courier addressed to the Corporate Trust Office.

 

The Trustee, by notice to the Company, may designate
additional or different addresses for subsequent notices or communications.

 

Any notice or communication sent to a Holder shall
be mailed to it by first class mail, postage prepaid, overnight courier or, in the case of a securities depositary, by electronic transmission,
at its address as it appears on the Note Register and shall be sufficiently given to it if so mailed within the time prescribed.

 

Failure to mail a notice or communication to a
Holder or any defect in it shall not affect its sufficiency with respect to other Holders. If a notice or communication is mailed in the
manner provided above, it is duly given, whether or not the addressee receives it.

 

The Trustee agrees to accept and act upon
instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar
unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons
designated to give such instructions or directions and containing specimen signatures of such designated persons, which such
incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. Any communication
sent to the Trustee by way of a digital signature must be by a digital signature provider specified in writing to the Trustee by an
Officer of the Company. If the Issuer elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar
electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such
instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or
indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict
or are inconsistent with a subsequent written instruction. The Issuer agrees to assume all risks arising out of the use of such
electronic methods to submit instructions and directions to the Trustee, including without limitation the risk of the Trustee acting
on unauthorized instructions, and the risk of interception and misuse by third parties.

with accepted practices at the Depositary.

Section 17.10.       
Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf
and subject to its direction in the authentication and delivery of Notes in connection with the original issuance thereof and transfers
and exchanges of Notes hereunder, including under Section 2.04, Section 2.05, Section 2.06, Section 2.07,
Section 10.04 and Section 15.05 as fully to all intents and purposes as though the authenticating agent had been expressly
authorized by this Indenture and those sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication
and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee”
and a certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement
hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at all times be a Person
eligible to serve as trustee hereunder pursuant to Section 7.08.

 

Any corporation or other entity into which any
authenticating agent may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from
any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation or other entity succeeding
to all or substantially all the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor entity or other entity is otherwise eligible under this Section 17.10, without the execution or filing
of any paper or any further act on the part of the parties hereto or the authenticating agent or such successor entity or other entity.

 

Any authenticating agent may at any time resign
by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating
agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation
or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible under this Section 17.10,
the Trustee may promptly appoint a successor authenticating agent, shall give written notice of such appointment to the Company and shall
mail notice of such appointment to all Holders as the names and addresses of such Holders appear on the Note Register.

 

The Company agrees to pay to the authenticating
agent from time to time reasonable compensation for its services although the Company may terminate the authenticating agent, if it determines
such agent’s fees to be unreasonable. The Company agrees to indemnify the authenticating agent as provided in Section 7.06.

 

The provisions of Section 7.02, Section
7.03, Section 7.04, Section 8.03 and this Section 17.10 shall be applicable to any authenticating agent.

 

If an authenticating agent is appointed pursuant
to this Section 17.10, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an
alternative certificate of authentication in the following form:

 

	
                                                                                            ,

the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signature and Records Act or any
other similar state laws based on the Uniform Electronic Transactions Act. The Trustee shall have the right to accept and act upon any

to this Indenture assumes all risks arising out of the use of electronic signatures and electronic methods to send Notices to the Trustee,
including without limitation the risk of the Trustee acting on an unauthorized Notice 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 a Notice in the form of
an original document bearing a manual signature be delivered to the Trustee in lieu of, or in addition to, any such electronic Notice.

by law) the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired.

 

Section 17.13.        Waiver
of Jury Trial. EACH OF THE COMPANY, THE HOLDERS BY ACCEPTANCE OF THE NOTES AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 

Section 17.14.       
Force Majeure. In no event shall the Trustee be responsible or liable for any failure or delay in the performance
of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation,
strikes, work stoppages, accidents, pandemics, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes
or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it
being understood that the Trustee shall use reasonable efforts that are consistent with accepted practices in the banking industry to
resume performance as soon as practicable under the circumstances.

 

Section 17.15.

called for under the Notes. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices per share
of the Common Stock, accrued interest payable on the Notes and the Conversion Rate of the Notes. The Company shall make all these calculations
in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company
shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent
is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will
forward the Company’s calculations to any Holder of Notes upon the written request of that Holder. Neither the Trustee nor the Conversion
Agent shall be responsible for making any calculations under the Notes or under this Indenture, and neither shall have any duty to monitor
the price of the shares of the Common Stock or otherwise be charged with knowledge of when the Notes are convertible.

 

Section 17.16.       
USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee,
like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify,
and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee.
The parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee
to satisfy the requirements of the USA PATRIOT Act.

 

Section 17.17.       
Foreign Account Tax Compliance Act (FATCA). In order to comply with applicable tax laws, rules and regulations
(inclusive of directives, guidelines and interpretations promulgated by competent authorities) in effect from time to time (“Applicable
Law”), the Company agrees (i) to provide to the Trustee sufficient information about Holders or other applicable parties and/or
transactions (including any modification to the terms of such transactions) so the Trustee can determine whether it has tax related obligations
under Applicable Law, and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under the Indenture
to the extent necessary to comply with Applicable Law for which the Trustee shall not have any liability.

[FORM OF REVERSE OF NOTE]

 

BRAEMAR HOTELS & RESORTS INC.

4.50% Convertible Senior Notes due 2026

 

This Note is one of a duly authorized issue of
Notes of the Company, designated as its 4.50% Convertible Senior Notes due 2026 (the “Notes”), initially limited to
the aggregate principal amount of $86,250,000 all issued or to be issued under and pursuant to an Indenture dated as of May 18, 2021 (the
 “Indenture”), among the Company and U.S. Bank National Association (the “Trustee”), to which Indenture
and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited
aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined
in this Note shall have the respective meanings set forth in the Indenture.

 

In case certain Events of Default shall have occurred
and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate
principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and
subject to the conditions and certain exceptions set forth in the Indenture.

 

Subject to the terms and conditions of the Indenture,
the Company will make all payments and deliveries in respect of the Fundamental Change Purchase Price on the Fundamental Change Purchase
Date, the Redemption Price on any Redemption Date and the principal amount on the Maturity Date, as the case may be, to the Holder who
surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the
United States that at the time of payment is legal tender for payment of public and private debts.

 

The Indenture contains provisions permitting the
Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances,
with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced
as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein.
It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the
Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture
and its consequences.

 

No reference herein to the Indenture and no provision
of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver,
as the case may be, the principal (including the Redemption Price and the Fundamental Change Purchase Price, if applicable) of, accrued
and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and
in the lawful money herein prescribed.

 

The Notes are issuable in registered form without
coupons in minimum denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred
to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate
principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or
Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result
of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes
surrendered for such exchange.

 

The Notes shall be redeemable at the Company’s
option in accordance with the terms and conditions specified in the Indenture.

 

Upon the occurrence of a Fundamental Change, the
Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or
any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price
equal to the Fundamental Change Purchase Price.

 

Subject to the provisions of the Indenture, the
Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture,
prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion
thereof that is $1,000 or an integral multiple thereof, for cash and, if applicable, shares of the Common Stock, if any, together with

AMENDMENT NO. 6

TO

THIRD AMENDED AND RESTATED

AGREEMENT OF LIMITED PARTNERSHIP

OF

BRAEMAR HOSPITALITY LIMITED PARTNERSHIP

 

May 18, 2021

 

This Amendment No. 6
to the Third Amended and Restated Agreement of Limited Partnership of Braemar Hospitality Limited Partnership (this “Amendment”)
is made as of May 18, 2021, by Braemar OP General Partner LLC, a Delaware limited liability company, as general partner (the “General
Partner”) of Braemar Hospitality Limited Partnership, a Delaware limited partnership (the “Partnership”),
pursuant to the authority granted in Section 11.1 of the Third Amended and Restated Agreement of Limited Partnership of Braemar
Hospitality Limited Partnership, dated March 7, 2017‎, as amended by Amendment No. 1 thereto dated as of April 23,
2018, Amendment No. 2 thereto dated as of November 20, 2018, Amendment No. 3 thereto dated as of December 3, 2019,
Amendment No. 4 thereto dated as of January 24, 2020, and Amendment No. 5 thereto dated as of April 2, 2021 (the “Partnership
Agreement”), for the purposes of documenting the issuance of convertible debt and providing for the potential conversion
of such debt into equity of the Partnership and issuance of additional Partnership Interests in the form of Common Partnership Units upon
such conversion. Capitalized terms used and not defined herein shall have the meanings set forth in the Partnership Agreement.

 

WHEREAS, the Board of
Directors of Braemar Hotels & Resorts Inc. (the “Company”) adopted resolutions establishing a
pricing committee (the “Pricing Committee”) at a meeting ‎held on May 6, 2021, and the duly authorized Pricing
Committee adopted resolutions on May ‎‎13, 2021 authorizing the issuance of $86,250,000 in aggregate principal amount
of‎ the Company's 4.50% Convertible ‎Senior ‎Notes due 2026 (including an additional $11,250,000 ‎principal amount issued upon the exercise of the initial
 ‎purchaser's option ‎to ‎purchase additional notes in full)‎ (the “REIT Convertible
Notes”) and providing that the Company intends to loan to the Partnership the proceeds from the offering of the REIT
Convertible Notes received by the Company on substantially the same terms as the REIT Convertible Notes (the “Partnership Corresponding Convertible
Debt”);‎

 

WHEREAS, Section 11.1(e) of
the Partnership Agreement permits the General Partner, ‎with the approval of the Limited Partners holding more than 50% of the Common
Percentage ‎Interests of the Limited Partners, to amend the Partnership Agreement for any purpose not ‎specifically addressed
otherwise in such Section 11.1(e);‎

 

    Page 1 

     

    

 

WHEREAS, the General Partner,
together with Ashford OP Limited Partner, as the ‎holder of more than 50% of the Common Percentage Interests of the Limited Partners
of the ‎Partnership, have determined to amend the Partnership Agreement to provide for the conversion of the Partnership Corresponding
Convertible Debt and the issuance of additional Partnership Interests in the form of Common Partnership Units upon the conversion of all
or any portion of the outstanding principal amount of the Partnership Corresponding Convertible Debt, which shall occur simultaneously
with any conversion of any REIT Convertible Notes into REIT Common Shares; and

 

WHEREAS, the General Partner
desires to so amend the Partnership Agreement as of the date first set forth above.

 

NOW, THEREFORE, in consideration
of the premises and for other good and valuable consideration, the receipt and sufficiency of which hereby are acknowledged, the General
Partner hereby amends the Partnership Agreement as follows:

 

1.            Article I
is amended to add the following defined terms in their respective alphabetical order ‎within Article I:‎

 

“Partnership
Corresponding Convertible Debt” shall mean the loan made by the Company‎, directly or through one or more Affiliates‎,
to the Partnership using proceeds received by the Company from the REIT Convertible Notes, as determined by the General Partner.‎

 

“REIT
Convertible Notes” shall mean the 4.50% Convertible Senior ‎Notes due 2026 issued by the Company as of the effective
date of this Amendment which are convertible into REIT Common Shares.

 

2.            Section 4.3
is amended to add new Section 4.3(f) to read in its entirety as follows:

 

(f)            Conversion/Redemption
of Partnership Corresponding Convertible Debt.

 

(i)            In
connection with the issuance by the Company of the REIT Convertible Notes, the Company, directly or through one or more Affiliates, as
determined appropriate by the General Partner, ‎shall loan the proceeds received by the Company from the issuance of such REIT Convertible
Notes to the Partnership which such loan shall constitute the Partnership Corresponding Convertible Debt. In connection with the conversion
of any REIT Convertible Notes into REIT Common Shares, the Partnership shall convert the necessary corresponding portion of
the Partnership Corresponding Convertible Debt ‎into Common Partnership Units and issue such Common Partnership Units to the Company,
or one or more of its Affiliates, as applicable. The number of Common Partnership Units into which such Partnership Corresponding Convertible
Debt is convertible shall be equal to the number of REIT Common Shares ‎into which such REIT Convertible Notes are then being converted,
determined based upon application of the Conversion Factor in effect on such date. Upon the conversion by the Company of any REIT Convertible
Notes into REIT Common Shares, the Company, directly or through one or more Affiliates, shall be ‎deemed to have made Capital
Contributions to the Partnership in the aggregate amount of the principle and interest converted into REIT Common Shares, as
determined by the General Partner.‎ In connection with the redemption or repurchase by the Company of any REIT Convertible Notes the
proceeds of which were used to advance any portion of the Partnership Corresponding Convertible Debt, the Partnership shall ‎provide
cash to the Company or one or more of its Affiliates for such purpose which shall be equal to the ‎applicable redemption or repurchase
price, plus all then accumulated and unpaid interest to, but excluding, the redemption or repurchase date, and a corresponding portion
of such Partnership Corresponding Convertible Debt shall ‎be deemed concurrently satisfied with respect to each REIT Convertible Note
so redeemed or repurchased by ‎the Company. ‎

 

    Page 2 

     

    

 

(ii)            The
Partners intend that the conversion feature of the Partnership Corresponding ‎Convertible Debt will be treated as ‎a noncompensatory
option within the ‎meaning of Section 1.721-‎‎2(f) of the Treasury Regulations. The Partners ‎recognize that
a conversion of any Partnership Corresponding Convertible Debt ‎into Common Partnership Units ‎would be an event described in
Exhibit B‎ as ‎requiring a revaluation of the Partnership’s ‎assets to their fair market values. ‎Notwithstanding
anything in this Agreement to the ‎contrary (including, without ‎limitation, Exhibit B), upon the conversion of any
 ‎ Partnership Corresponding ‎Convertible Debt to Common Partnership Units, the Capital Accounts of the ‎Partners (including
the ‎converting Partner) shall be adjusted immediately after ‎the conversion of the ‎ Partnership Corresponding Convertible
Debt to reflect a ‎revaluation of the Partnership’s assets to their fair market ‎values on the date of ‎adjustment.
In determining the Capital Accounts of the Partners ‎‎(including the ‎converting Partner) for purposes of the preceding sentence,
the ‎Partnership shall ‎specially allocate any unrealized income, gain, loss or deduction in the ‎‎Partnership’s
assets (that has not been previously reflected in the Partners’ ‎Capital ‎Accounts) among the Partners (including the converting
Partner) in ‎‎accordance with Section 1.704-1(b)(2)(iv)(s) of the Treasury Regulations in such ‎a manner so ‎as
to properly reflect the Partners’ relative rights and entitlements to ‎distributions under ‎this Agreement (and, for purposes
of clarification, is intended ‎to result in a Capital ‎Account balance for the converting Partner with respect to ‎the Common
Partnership Units acquired ‎pursuant to the conversion of ‎Partnership Corresponding Convertible Debt that equals the amount that
would ‎be ‎distributed to such Partner with respect to such Common Partnership Units if ‎immediately after the ‎conversion
of such Partnership Corresponding Convertible ‎Debt all of the assets of the Partnership were sold for their ‎respective fair
market ‎values, the liabilities of ‎the Partnership were paid in full, and liquidating ‎distributions were made pursuant to
 ‎Section 10.4 (assuming distributions to the ‎holders of Common Partnership Units were made in accordance with their
 ‎respective Common Percentage Interests)‎ (the “Conversion Target Account”)). ‎If, after making the allocations
 ‎described in the preceding sentence, the ‎converting Partner’s Capital Account still does ‎not reflect the Conversion
Target ‎Account, then the Partnership’s capital will be ‎reallocated between the existing ‎Partners and the converting
Partner so that the ‎converting Partner’s Capital ‎Account reflects the Conversion Target Account (a ‎‎“Conversion
Capital Account ‎Reallocation”). Any increase or reduction in the Capital ‎Accounts of the existing ‎Partners that
occurs as a result of a Conversion Capital ‎Account Reallocation ‎shall be allocated among the existing Partners in a manner similar
to ‎Section 5.1. ‎In the event of any Conversion Capital Account Reallocation, corrective ‎‎allocations of
gross income and gain or gross loss or deductions subsequent to the ‎‎Conversion Capital Account Reallocation will first be allocated
to the Partners ‎until the ‎Conversion Capital Account Reallocations are eliminated in accordance ‎with Section 1.704-1(b)(4)(x) of
the Treasury ‎Regulations as determined by the ‎General Partner in its reasonable ‎discretion..‎

3.            Except
as modified herein, all terms and conditions of the Partnership Agreement shall remain in full force and effect, which terms and conditions
the General Partner hereby ratifies and confirms.

 

4.            This
Amendment shall be construed and enforced in accordance with and governed by the laws of the state of Delaware, without regard to conflicts
of law.

 

5.            If
any provision of this Amendment is or becomes invalid, illegal or unenforceable in any respect, the validity, legality and enforceability
of the remaining provisions contained herein shall not be affected thereby.
