Re: Confirmatory Employment Letter
Dear Bruce:
This letter agreement (the “Agreement”) is entered into between Bruce C. Felt (“you”) and Domo, Inc. (the “Company” or “we”), effective as of June 15, 2018 (the “Effective Date”), to confirm the terms and conditions of your employment with the Company as of the Effective Date.  This Agreement supersedes and replaces any and all employment terms, compensation, or benefits you may have had or to which you may have been entitled prior to the Effective Date.
		
	1.
	Title; Position.  You will continue to serve as the Company’s Chief Financial Officer.  You also will continue to report to the Company’s Chief Executive Officer and will perform the duties and responsibilities customary for such position and such other related duties as are lawfully assigned by the Company’s Chief Executive Officer.  While you render services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company.  You may engage in civic and not‐for-profit activities as long as such activities do not interfere with the performance of your duties under this Agreement.  By signing this Agreement, you confirm that you have no contractual commitments or other legal obligations that would prohibit you from performing your duties for the Company.

		
	2.
	Base Salary.  As of the Effective Date, your annual base salary will be $375,000, which will be payable, less any applicable withholdings, in accordance with the Company’s normal payroll practices.  Your annual base salary will be subject to review and adjustment from time to time by our Board or its Compensation Committee (the “Committee”), as applicable, in its sole discretion.

		
	3.
	Annual Bonus.  For the Company’s 2019 fiscal year, you will have the opportunity to earn a target annual cash bonus equal to $187,500, based on achieving performance objectives established by the Board or Committee, as applicable, in its sole discretion and payable upon achievement of those objectives as determined by the Committee.  Unless determined otherwise by the Board or Committee, as applicable, any such bonus will be subject to your continued 

employment through and until the date of payment.  Your annual bonus opportunity and the applicable terms and conditions may be adjusted from time to time by our Board or the Committee, as applicable, in its sole discretion.
		
	4.
	Equity Awards.  You will be eligible to receive awards of stock options, restricted stock units or other equity awards pursuant to any plans or arrangements the Company may have in effect from time to time.  The Board or Committee, as applicable, will determine in its sole discretion whether you will be granted any such equity awards and the terms of any such award in accordance with the terms of any applicable plan or arrangement that may be in effect from time to time.

		
	5.
	Employee Benefits.  You will continue to be eligible to participate in the benefit plans and programs established by the Company for its employees from time to time, subject to their applicable terms and conditions, including without limitation any eligibility requirements. The Company reserves the right to modify, amend, suspend or terminate the benefit plans and programs it offers to its employees at any time.

		
	6.
	Travel Expenses. During your employment with the Company while your primary place of residence is in California, you will be eligible to be reimbursed by the Company for any and all Travel Expenses (as defined below), provided that you timely submit supporting receipts and/or documentation in form and substance reasonably acceptable to the Company, in accordance with the Company’s reimbursement policy (the “Reimbursement Policy”), as in effect from time to time.  Such reimbursements will be paid to you at such time or times as specified in the Reimbursement Policy.  In no event, however, will any reimbursement occur later than the fifteenth (15) day of the third month following the later of (i) the end of the Company’s fiscal year in which such Travel Expenses are incurred or (ii) the end of the calendar year in which such Travel Expenses are incurred.  “Travel Expenses” will include ordinary and reasonable expenses incurred by you for you and your family to travel from your personal residence in California to the Company’s Utah headquarters, including expenses for first class airfare for your spouse, lodging in close proximity to the Company’s Utah headquarters, and a rental car.  Your airfare will be an upgradable coach seat for such travel, with any exceptions from time to time as determined in your reasonable discretion, as appropriate.

In addition, to the extent any reimbursement for Travel Expenses that you receive is taxable to you, you will receive a “gross-up” payment equal to the applicable federal and state taxes on such reimbursement payment, as estimated by the Company in good faith, at the same time as the applicable reimbursement is made.
		
	7.
	Severance.  You will be eligible to enter into a Change in Control and Severance Agreement (the “Severance Agreement”) applicable to you based on your position within the Company.  The Severance Agreement will specify the severance payments and benefits you may become entitled to receive in connection with certain qualifying terminations of your employment with 

the Company.  These protections will supersede all other severance payments and benefits to which you otherwise may be entitled, or may become entitled in the future, under any plan, program or policy that the Company may have in effect from time to time.  For purposes of clarification, any severance benefits or arrangements that may have applied to you before the Effective Date no longer will apply and you will have no rights or entitlements under any such plans, programs, agreements or arrangements.
		
	8.
	Confidentiality Agreement. As an employee of the Company, you will continue to have access to certain confidential information of the Company and you may, during the course of your employment, develop certain information or inventions that will be the property of the Company.  To protect the interests of the Company, your acceptance of this Agreement confirms that the terms of the Company’s At‐Will Employment, Confidential Information, Invention Assignment, Nonsolicitation, and Arbitration Agreement you previously signed with the Company (the “Confidentiality Agreement”) still apply.

		
	9.
	At-Will Employment.  This Agreement does not imply any right to your continued employment for any period with the Company or any of its affiliates.  Your employment with the Company will continue to be “at will.” It is for no specified term, and may be terminated by you or the Company at any time, with or without cause or advance notice.

		
	10.
	Protected Activity Not Prohibited.  Nothing in this Agreement or in any other agreement between you and the Company, as applicable, will in any way limit or prohibit you from engaging for a lawful purpose in any Protected Activity.  For purposes of this Agreement, “Protected Activity” means filing a charge, complaint, or report with, or otherwise communicating, cooperating, or participating in any investigation or proceeding that may be conducted by, any state, federal, or local governmental agency or commission, including the U.S. Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (the “Government Agencies”).  You understand that in connection with such Protected Activity, you are permitted to disclose documents or other information as permitted by law, and without giving notice to, or receiving authorization from, the Company.  Notwithstanding the foregoing, you agree to take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Company confidential information under the Confidentiality Agreement to any parties other than the Government Agencies.  You further understand that “Protected Activity” does not include the disclosure of any Company attorney-client privileged communications.  Any language in the Confidentiality Agreement regarding your right to engage in Protected Activity that conflicts with, or is contrary to, this paragraph is superseded by this Agreement.  In addition, pursuant to the Defend Trade Secrets Act of 2016, you are notified that an individual will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made in confidence to a federal, state, or local government official (directly or indirectly) or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) is made in a complaint or other document filed in a lawsuit 

or other proceeding, if (and only if) such filing is made under seal.  In addition, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the individual’s attorney and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.
		
	11.
	Miscellaneous.  This Agreement, together with the Confidentiality Agreement, the Severance Agreement and any outstanding equity awards granted to you by the Company under its 2011 Equity Incentive Plan and the applicable award agreements thereunder, constitute the entire agreement between you and the Company regarding the material terms and conditions of your employment, and they supersede and replace all prior negotiations, representations or agreements between you and the Company.  This Agreement may be modified only by a written agreement signed by you and a duly authorized officer of the Company.

the Base Indenture of holders of multiple series of Securities voting together as a single class, the consent of Holders of the
Notes voting as a separate class shall also be required and the same threshold shall apply. The provisions of this Supplemental
Indenture shall supersede, with respect to the Notes, any conflicting provisions in the Base Indenture.

in writing, the Security Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to
the account of the Depositary or its nominee, in accordance with the procedures of the Depositary. The third paragraph of Section
2.07 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this ‎Section 2.04(b) and ‎Section
2.04‎(c), and any reference in the Base Indenture to such paragraph of Section 2.07 shall, with respect to the Notes, be deemed

of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Issuer shall deposit with the Trustee
an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory
to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Issuer shall fix a
special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior
to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment.
The Issuer shall promptly notify the Trustee in writing of such special record date and the Trustee, in the name and at the expense
of the Issuer, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be
mailed, first-class postage prepaid, to each Holder at its address as it appears in the Security Register, not less than 10 days
prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor
having been so mailed, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor
Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following
clause (ii) of this ‎Section 2.04‎(c).

 

(ii)         The
Issuer may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities
exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may
be required by such exchange or automated quotation system, if, after notice given by the Issuer to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.05. Exchange and Registration
of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The third paragraph of Section 2.08 of the Base Indenture shall,
with respect to the Notes, be superseded in its entirety by this ‎Section 2.05‎(a), and any reference in the Base Indenture
to such paragraph of Section 2.08 shall, with respect to the Notes, be deemed to refer instead to this ‎Section 2.05‎(a),
as the context may require. Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Issuer pursuant to Section
3.02 of the Base Indenture. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee
shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers
not contemporaneously outstanding. All Notes surrendered upon any exchange or transfer provided for in the Indenture shall be promptly
cancelled and disposed of by the Trustee in accordance with the Trustee’s customary procedures and the record retention requirements
of applicable securities laws. Upon request, the Trustee shall certify to the Issuer as to such cancellation.

 

(b)          The
fifth paragraph of Section 2.08 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this ‎Section
2.05‎(b), and any reference in the Base Indenture to such paragraph of Section 2.08 shall, with respect to the Notes, be deemed
to refer instead to this ‎Section 2.05‎(b), as the context may require. No service charge shall be imposed by the Issuer,
the Trustee, the Security Registrar, any co-Security Registrar or the Paying Agent for any exchange or registration of transfer
of Notes, but the Issuer 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 new Notes issued upon such exchange or registration
of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

 

(c)          The
sixth paragraph of Section 2.08 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section
2.05‎(c), and any reference in the Base Indenture to such paragraph of Section 2.08 shall, with respect to the Notes, be deemed
to refer instead to this Section 2.05‎(c), as the context may require. None of the Issuer, the Trustee or the Security Registrar
shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is
surrendered for conversion, such portion thereof surrendered for conversion; or (ii) any Notes, or a portion of any Note, surrendered
for repurchase (and not withdrawn) in accordance with ‎Article 15 or
(iii) any Notes selected for redemption in accordance with ‎Article
16, except the unredeemed portion of any Note being redeemed in part.

 

All Notes issued upon any registration of
transfer or exchange of Notes in accordance with the Indenture shall be the valid obligations of the Issuer, evidencing the same
debt, and entitled to the same benefits under the Indenture as the Notes surrendered upon such registration of transfer or exchange.

 

(d)          So
long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the
second paragraph of ‎Section 2.05(e) all Notes shall be represented by one or more Notes in global form (each, a “Global
Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial
interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but
not the Trustee or the Custodian) in accordance with the Indenture and the procedures of the Depositary therefor and shall be settled
in same-day funds.

 

    	 	16	 

     

    

 

The Depositary shall be a clearing agency
registered under the Exchange Act. The Issuer 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.

 

The ninth and tenth paragraphs of Section
2.08 of the Base Indenture shall be superseded by this paragraph of Section 2.05‎(d), and any reference in the Base Indenture
to such paragraphs of such Section 2.08 thereof shall be deemed to refer instead to this paragraph of Section 2.05‎(d). At
such time as all interests in a Global Note have been converted, canceled, repurchased, redeemed 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, redeemed 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 Issuer, the Trustee or any agent
of the Issuer 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.

 

(e)          The
eighth paragraph of Section 2.08 of the Base Indenture shall be superseded by this ‎Section 2.05(e), and any reference in the
Base Indenture to such paragraph of such Section 2.08 thereof shall be deemed to refer instead to this ‎Section 2.05(e).

 

If (i) the Depositary notifies the Issuer
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, (iii) a beneficial owner of any Global Note requests that its beneficial
interest therein be issued as a Physical Note and the Issuer, in its sole discretion, so permits or (iv) an Event of Default with
respect to the Notes has occurred and is continuing and a beneficial owner of any Global Note requests that its beneficial interest
therein be issued as a Physical Note, the Issuer shall execute, and the Trustee, upon receipt of an Officer’s Certificate,
an Issuer Order and an Opinion of Counsel for the authentication and delivery of Notes, shall authenticate and deliver (x) in the
case of clause (iii) or (iv), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such
Global 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.

 

    	 	17	 

     

    

 

Physical Notes issued in exchange for all
or a part of the Global Note pursuant to this ‎Section 2.05(e) 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, or, in the case of clause (iii)
of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication,
the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

 

(f)           Any
Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the Issuer
(or any Person who was an Affiliate of the Issuer at any time during the three months preceding) may not be resold by such Affiliate
(or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration
requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being
a “restricted security” (as defined under Rule 144 under the Securities Act). The Issuer shall cause any Note that
is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with ‎Section 2.07.

 

Section 2.06. Mutilated, Destroyed, Lost
or Stolen Notes. The first sentence of the second paragraph of Section 2.09 of the Base Indenture shall be superseded by this
 ‎Section 2.06, and any reference in the Base Indenture to such sentence of such Section 2.09 thereof shall be deemed to refer
instead to this ‎Section 2.06. No service charge shall be imposed by the Issuer, the Trustee, the Security Registrar, any co-Security
Registrar or the Paying Agent upon the issuance of any substitute Note, but the Issuer 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.

 

Section 2.07. Cancellation of Notes Paid,
Converted, Etc. Section 2.10 of the Base Indenture shall be superseded by this ‎Section 2.07, and any reference in the
Base Indenture to such Section 2.10 thereof shall be deemed to refer instead to this ‎Section 2.07. The Issuer shall cause
all Notes surrendered for the purpose of payment, repurchase, redemption, registration of transfer or exchange or conversion (for
the avoidance of doubt, other than pursuant to Section 14.12), if surrendered to any Person other than the Trustee (including any
of the Issuer’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 except for Notes surrendered for registration of transfer or exchange, no
Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of the Indenture. The Trustee
shall dispose of cancelled Notes in accordance with its customary procedures and the record retention requirements of applicable
securities laws. Upon request, the Trustee shall certify to the Issuer as to such cancellation.

 

    	 	18	 

     

    

 

Section 2.08. CUSIP Numbers. The
Issuer 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. The Issuer shall promptly notify the Trustee in writing
of any change in the “CUSIP” numbers.

 

Section 2.09. Additional Notes; Repurchases.
The last paragraph of Section 2.03 of the Base Indenture shall be superseded by this ‎Section 2.09, and any reference in the
Base Indenture to such paragraph thereof shall be deemed to refer instead to this ‎Section 2.09. The Issuer may, without the
consent of the Holders and notwithstanding ‎Section 2.02, reopen the Indenture and issue additional Notes under the Indenture
with the same terms and with the same CUSIP number as the Notes initially issued hereunder (other than differences in the issue
price, issue date 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 securities
law or federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such
additional Notes, the Issuer shall deliver to the Trustee an Issuer Order, an Officer’s Certificate and an Opinion of Counsel,
such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section
11.05 of the Base Indenture, as the Trustee shall reasonably request. In addition, the Issuer may, to the extent permitted
by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Issuer), repurchase Notes in the open
market or otherwise, with or without notice to Holders, whether by the Issuer or its Subsidiaries or through a private or public
tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives.
The Issuer 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 2.07 and such Notes shall no longer be considered
Outstanding under the Indenture upon their repurchase.

Section 3.01. Applicability of
Article 10 of the Base Indenture.

 

(a)          Section
10.01 of the Base Indenture shall not apply to the Notes. Instead the provisions set forth in this ‎Article 3 shall,
with respect to the Notes, supersede in their entirety Section 10.01 of the Base Indenture, and all references in the Base Indenture
to Section 10.01 thereof and the provisions therein, as the case

Section 3.02. Satisfaction and Discharge.
The Indenture shall upon request of the Issuer contained in an Officer’s Certificate cease to be of further effect, and the
Trustee, at the expense of the Issuer, shall execute such instruments reasonably requested by the Issuer acknowledging satisfaction
and discharge of the Indenture, when (a) (i) all Notes theretofore authenticated and delivered (other than Notes which have been
destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section
2.09 of the Base Indenture) have been delivered to the Trustee for cancellation; or (ii) the Issuer has deposited with the
Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any
Redemption Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or cash, shares of Common Stock or
a combination thereof, as applicable, solely to satisfy the Issuer’s Conversion Obligation, sufficient to pay all of the
Outstanding Notes and all other sums due and payable under the Indenture by the Issuer; and (b) the Issuer has delivered to the
Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for
relating to the satisfaction and discharge of the Indenture have been complied with. Notwithstanding the satisfaction and discharge
of the Indenture, the obligations of the Issuer to the Trustee under Section
6.06 of the Base Indenture shall survive.

Particular Covenants of the Issuer

 

Section 4.01. Paying Agent and Conversion
Agent. The Issuer hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian and Conversion

4.02, and any reference in the Base Indenture to such Section 10.04 shall, with respect to the Notes, be deemed to refer instead
to this ‎Section 4.02, as the context may require. Notwithstanding anything in the Base Indenture to the contrary, any money
and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment
of the principal (including the Redemption Price and the Fundamental Change Repurchase 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 Repurchase Price, if applicable), interest or consideration due upon conversion
has become due and payable shall be paid to the Issuer on request of the Issuer contained in an Officer’s Certificate, or
(if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured
general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect
to such trust money and shares of Common Stock, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided,
however, that the Issuer shall, at its sole expense, cause to be published once, in a newspaper published in the English
language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York,

Section
4.03. Annual Compliance Certificate. Within 120 days after the end of each fiscal year of the Issuer ending after
the date hereof, the Issuer will deliver to the Trustee a written statement covering the previous fiscal year, signed by two of

to the Notes, be superseded in its entirety by this ‎Section 4.03,

to receive confidential treatment by the Commission, any correspondence with the Commission and any redacted material). Any such
document or report that the Issuer files with the Commission via the Commission’s EDGAR system shall be deemed to be filed

in the immediately preceding paragraph 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 Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively
rely on an Officer’s Certificate).

 

Section 4.05. Stay, Extension and Usury
Laws. The Issuer 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 Issuer 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 the Indenture; and the Issuer
(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 4.06. Further Instruments and
Acts. Upon request of the Trustee, the Issuer will execute and deliver such further instruments and do such further acts as
may be reasonably necessary or proper to carry out more effectively the purposes of the Indenture.

 

Section 4.07. Additional Amounts.

 

(a)          If
the Issuer amalgamates, consolidates with, merges with or into, or sells, conveys, transfers or leases its property and assets
substantially as an entirety to, any Person and the resulting, surviving or transferee Person is not organized and validly existing
under the laws of the United States of America, any state thereof or the District of Columbia (such Person or any successor thereto,
the “Surviving Entity”), then all payments and deliveries made by, or on behalf
of, the Surviving Entity under or with respect to the Notes, including, but not limited to, payments of principal (including, if
applicable, the Fundamental Change Repurchase Price and the Redemption Price), payments of interest and deliveries of cash, Common
Stock or other Reference Property (together with payment of cash in lieu of any fractional shares of Common Stock) upon conversion,
shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental
charges of whatever nature (“Taxes”) imposed or levied by or within the jurisdiction,
excluding the United States, in which the Surviving Entity is, for tax purposes, organized or resident or doing business or through
which payment is made or deemed made by or on behalf of the Surviving Entity for purposes of the tax law of that jurisdiction (or
any political subdivision or taxing authority thereof or therein) (each, as applicable, a “Relevant Taxing Jurisdiction”),
unless such withholding or deduction is required by law or by regulation or governmental policy having the force of law. In the
event that any such withholding or deduction is so required, the Surviving Entity shall pay to the Holder of each Note such additional
amounts (the “Additional Amounts”) as may be necessary to ensure that the
net amount received by the beneficial owners after such withholding or deduction (and after deducting any Taxes imposed or levied
by a Relevant Taxing Jurisdiction on the Additional Amounts) shall equal the amounts that would have been received by such beneficial
owners had no such withholding or deduction been required; provided that no Additional Amounts will be payable for or on
account of:

 

(A)         any
Taxes to the extent such Taxes would not have been imposed but for:

 

(1)         the
existence of any present or former connection between the Holder or such beneficial owners of such Note and the Relevant Taxing
Jurisdiction, including, without limitation, being or having been a national, domiciliary or resident of such Relevant Taxing Jurisdiction
or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having
or having had a permanent establishment therein, but excluding the mere holding or enforcement of such Note or the receipt of payments
thereunder;

 

(2)         the
presentation of such Note (in cases in which presentation is required) more than 30 days after the later of the date on which the
payment of the principal of (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) and interest
on such Note or the delivery of cash, Common Stock and other Reference Property (together with payment of cash in lieu of any fractional
shares of Common Stock) upon conversion of such Note became due and payable pursuant to the terms thereof or was made or duly provided
for; or

 

    	 	22	 

     

    

 

(3)         the
failure of the Holder or such beneficial owners, to the extent they were legally entitled to do so, to comply with a timely request
from the Surviving Entity to provide certification, information, documents or other evidence concerning such Holder’s or
such beneficial owners’ nationality, residence, identity or connection with the Relevant Taxing Jurisdiction, or to make
any declaration or satisfy any other reporting requirement relating to such matters, if and to the extent that due and timely compliance
with such request is required by statute, regulation, treaty or administrative practice of the Relevant Taxing Jurisdiction in
order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise been payable to such
Holder or beneficial owners;

 

(B)         any
estate, inheritance, gift, sale, transfer, excise, personal property or similar Taxes;

 

(C)         any
Taxes to the extent such Taxes result from the presentation of any Note for payment (where presentation is required for payment)
and the payment can be made without such withholding or deduction by the presentation of the Note for payment to at least one other
Paying Agent in a member state of the European Union;

 

(D)         any
Taxes that are payable otherwise than by withholding from payments under or with respect to the Notes;

 

(E)         any
Taxes required by sections 1471 through 1474 of the United States Internal Revenue Code of 1986, as amended (“FATCA”),
any current or future Treasury Regulations or rulings promulgated thereunder, any law, regulation or other official guidance enacted
in any jurisdiction implementing FATCA, any intergovernmental agreement between the United States and any other jurisdiction to
implement FATCA or any law enacted by such other jurisdiction to give effect to such agreement, or any agreement with the U.S.
Internal Revenue Service under FATCA; or

 

(F)         any
combination of Taxes referred to in the preceding clauses (A) through (E).

 

Furthermore, Additional Amounts shall not
be paid for any Taxes with respect to any payment of the principal of (including the Fundamental Change Repurchase Price and the
Redemption Price, if applicable) and interest on such Note or the delivery of cash, Common Stock or other Reference Property (together
with payment of cash in lieu of any fractional shares of Common Stock) upon conversion of such Note to a Holder, if the Holder
is a fiduciary, partnership or Person other than the sole beneficial owner of that payment to the extent that such payment would
be required to be included in the income under the laws of the Relevant Taxing Jurisdiction, for tax purposes, of a beneficiary
or settlor with respect to the fiduciary, a partner or member of that partnership or a beneficial owner who would not have been
entitled to such Additional Amounts had that beneficiary, settlor, partner, member or beneficial owner been the Holder thereof.

 

    	 	23	 

     

    

 

(b)          Any
reference in the Indenture or the Notes in any context to the delivery of cash, Common Stock or other Reference Property (together
with payment of cash in lieu of any fractional shares of Common Stock) upon conversion of any Note or the payment of principal
of (including the Fundamental Change Repurchase Price and the Redemption Price, if applicable) and interest on, any Note or any
other amount payable with respect to such Note, shall be deemed to include payment of Additional Amounts to the extent that, in
such context, Additional Amounts are, were or would be payable in respect thereof pursuant to this Section 4.07.

 

(c)          As
a condition to receiving any Additional Amounts, each Holder entitled to any Additional Amounts shall cooperate with the Surviving
Entity and the Trustee in complying with any timely request from the Surviving Entity to provide any certification, information,
documents or other evidence to confirm such Holder’s nationality, residence, identity or connection with the Relevant Taxing
Jurisdiction (or to make any declaration or satisfy any other reporting requirement relating to such matters), if and to the extent
that due and timely compliance with such request is required by statute, regulation, treaty or administrative practice of the Relevant
Taxing Jurisdiction in order to reduce or eliminate any withholding or deduction as to which Additional Amounts would have otherwise
been payable to such Holder. Each Holder entitled to any Additional Amounts shall cooperate with the Surviving Entity and the Trustee
in determining the applicable withholding tax rate and the amount of Additional Amounts payable in respect thereof to assist the
Surviving Entity or Trustee in determining the applicable withholding tax rate and the amount of Additional Amounts payable in
respect thereof. The Issuer shall furnish to the Trustee documentation reasonably satisfactory to the Trustee evidencing payment
of any Taxes so deducted or withheld and the amount of any Additional Amounts payable thereon. Copies of such documentation will
be made available by the Trustee to the relevant Holders upon written request to the Trustee.

 

(d)          The
obligations under this Section 4.07 shall survive any termination or discharge of the Indenture and any transfer by a Holder or
beneficial owner of its Notes.

Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being
declared due and payable without such indebtedness having been discharged or the acceleration of payment of such indebtedness having
been cured, rescinded, waived or annulled within 30 days after written notice of such acceleration having been received by the
Issuer or such Significant Subsidiary or (ii) constituting a failure to pay the principal or interest of any such debt when due
and payable (after any applicable grace period) at its stated maturity (or, if later, at the expiration of any grace period provided

    	 	25	 

     

    

 

(h)          a
final judgment for the payment of $35,000,000 (or its foreign currency equivalent) or more (excluding any amounts covered by insurance)
in the aggregate rendered against the Issuer or any Subsidiary of the Issuer, which judgment is not discharged or stayed within
60 days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on

(i)           the

similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar
official of the Issuer or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such

(j)           an

official of the Issuer or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other
proceeding shall remain undismissed and unstayed for a period of 60 consecutive days.

 

Section 6.03. Acceleration; Rescission
and Annulment. 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 6.02(i) or ‎Section 6.02(j) with respect to the Issuer
or any of its Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, either
the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding, determined in accordance with Section
7.04 of the Base Indenture, or the Trustee by notice in writing to the Issuer (and to the Trustee if given by Holders),
may, subject to the provisions of the Indenture, declare 100% of the principal of, and accrued and unpaid interest, if any, on
all the Outstanding Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically
be immediately due and payable. If an Event of Default specified in ‎Section 6.02(i) or ‎Section 6.02(j) with respect to
the Issuer or any Significant Subsidiary occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if
any, on, all Outstanding Notes shall become and shall automatically be immediately due and payable.

 

    	 	26	 

     

    

 

The immediately preceding paragraph, however,
is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable,
and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided,
the Issuer shall pay or deliver, as the case may be, or shall deposit with the Trustee an amount of cash and/or shares of Common
Stock (or other Reference Property) sufficient to pay all installments of accrued and unpaid interest upon all Notes, all amounts
of consideration due upon the conversion of any and all Notes that had been converted, and the principal of any and all Notes that
shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest, to
the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes
at such time plus one percent) and amounts due to the Trustee pursuant to Section
6.06 of the Base Indenture, and if (1) rescission would not conflict with any judgment or decree of a court of competent
jurisdiction and (2) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of
and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured
or waived pursuant to ‎Section 6.10, then and in every such case (except as provided in the immediately succeeding sentence)
the Holders of a majority in aggregate principal amount of the Notes then Outstanding, by written notice to the Issuer and to the
Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences
and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every
purpose of the Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default
or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver
or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of
the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid
interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case
may be, the consideration due upon conversion of the Notes.

 

Section 6.04. Additional Interest.
Notwithstanding anything in the Indenture or in the Notes to the contrary, to the extent the Issuer elects, the sole remedy for
an Event of Default relating to the Issuer’s failure to comply with its obligations as set forth in ‎Section 4.04 (the
 “Reporting Obligations”) shall for the first 180 days after the occurrence of such an Event of Default (which,
for the avoidance of doubt, shall not commence until the notice described in Section 6.02(f) has been given, and the related 90-day
period described in Section 6.02(f) has passed) consist exclusively of the right to receive Additional Interest on the Notes at
a rate equal to (x) 0.25% per annum of the principal amount of the Notes Outstanding for each day during the first 90-day
period after the occurrence of such Event of Default and (y) 0.50% per annum of the principal amount of the Notes Outstanding for
each day from the 91st day until the 180th day following the occurrence of such Event of Default, in each case, during which such
Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs.

 

If the Issuer so elects to pay Additional
Interest, any such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable
on the Notes. On the 181st day after such Event of Default (if the Event of Default relating to the Issuer’s failure to comply
with the Reporting Obligations is not cured or waived prior to such 181st day), the Notes shall be immediately subject to acceleration
as provided in ‎Section 6.03. The provisions of this ‎Section 6.04 will not affect the rights of Holders of Notes in the
event of the occurrence of any Event of Default other than the Issuer’s failure to comply with its Reporting Obligations.
In the event the Issuer does not elect to pay Additional Interest following an Event of Default relating to the Reporting Obligations
in accordance with this ‎Section 6.04 or the Issuer elected 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 6.03.

 

    	 	27	 

     

    

 

In order to elect to pay Additional Interest
as the sole remedy during the first 180 days after the occurrence of any Event of Default relating to the failure by the Issuer
to comply with the Reporting Obligations, in accordance with this ‎Section 6.04, the Issuer must notify in writing all Holders
of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period (which,
for the avoidance of doubt, shall not commence until the notice described in Section 6.02(f) has been given, and the related 90-day
period described in Section 6.02(f) has passed). Upon the failure to timely give such notice, the Notes shall be immediately
subject to acceleration as provided in ‎Section 6.03.

 

Section 6.05. Payments of Notes on Default;
Suit Therefor. Subject to ‎Section 6.03, if an Event of Default described in clause ‎(a) or ‎(b) of ‎Section
6.02 shall have occurred, the Issuer 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 plus one percent, and, in addition thereto, such further
amount as shall be sufficient to cover any amounts due to the Trustee under Section
6.06 of the Base Indenture. If the Issuer 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 Issuer 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 Issuer
or any other obligor upon the Notes, wherever situated.

 

In the event there shall be pending proceedings
for the bankruptcy or for the reorganization of the Issuer 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 Issuer or such other obligor, the property of the
Issuer or such other obligor, or in the event of any other judicial proceedings relative to the Issuer or such other obligor upon
the Notes, or to the creditors or property of the Issuer 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 6.05, 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, its agents and counsel) and of
the Holders allowed in such judicial proceedings relative to the Issuer 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
6.06 of the Base Indenture; 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 agents and counsel fees, and including
any other amounts due to the Trustee under Section 6.06 of the Base Indenture,
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.

 

    	 	28	 

     

    

 

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 the 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, its agents and 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 the 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 the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant
to ‎Section 6.10 or any rescission and annulment pursuant to ‎Section 6.03 or for any other reason or shall have been determined
adversely to the Trustee, then and in every such case the Issuer, 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 Issuer, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

 

Section 6.06. Application of Monies Collected
by Trustee. Any monies or property collected by the Trustee pursuant to this ‎Article 6 with respect to the Notes shall
be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies or property, 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 6.06 of the Base Indenture;

 

    	 	29	 

     

    

 

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, plus one percent, 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
the Redemption Price and the Fundamental Change Repurchase Price, if applicable, 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, plus
one percent, 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 the Redemption Price and the Fundamental Change Repurchase Price, if applicable, 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 the Redemption Price and the Fundamental Change Repurchase Price, if applicable, and any cash due
upon conversion) and accrued and unpaid interest; and

 

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

 

Section 6.07. Proceedings by Holders.
Except to enforce the right to receive payment of principal (including the Redemption Price and the Fundamental Change Repurchase
Price, if applicable) 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 the Indenture to institute any suit,
action or proceeding in equity or at law upon or under or with respect to the 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
Holders shall have offered to the Trustee such security or indemnity reasonably satisfactory to the Trustee against any cost, loss,
liability or expense (including fees and expenses of its counsel) to be incurred therein or thereby;

 

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

 

    	 	30	 

     

    

 

(e)          no
direction that, in the opinion of the Trustee, 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 within such 60-day period pursuant to
 ‎Section 6.10,

 

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 the Indenture to affect, disturb
or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder,
or to enforce any right under the 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 6.07, 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 the
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 Redemption Price and the Fundamental Change Repurchase 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 the 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 Issuer shall not be impaired or affected without the consent of
such Holder.

 

Section 6.08. 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 the
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 the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal
or equitable right vested in the Trustee by the Indenture or by law.

 

Section 6.09. Remedies Cumulative and
Continuing. Except as provided in the last paragraph of Section 2.09
of the Base Indenture and ‎Section 6.04, 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 the 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 Default
or 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 6.07, 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.

 

    	 	31	 

     

    

 

Section 6.10. 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 7.04 of the
Base Indenture 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 the 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 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
7.04 of the Base Indenture 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 and the Fundamental Change Repurchase Price, if applicable) of, the Notes when due that has not been cured
pursuant to the provisions of ‎Section 6.02, (ii) a failure by the Issuer 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 Issuer, 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 6.10, said Default or Event of Default shall for
all purposes of the Notes and the 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 6.11. Notice of Defaults.
The Issuer shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the occurrence of any Event
of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status
and the action that the Issuer is taking or proposing to take in respect thereof. The Trustee shall, within 90 days after the occurrence
and continuance of a Default of which a Responsible Officer has actual knowledge, mail to all Holders as the names and addresses
of such Holders appear upon the Security Register (in the case of Physical Notes) or deliver to all Holders in accordance with
the procedures of the Depositary (in the case of Global Notes) notice of all 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 Repurchase 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 Trustee in good faith determines that the withholding
of such notice is in the interests of the Holders. This ‎Section 6.11 shall supersede Section 5.11 of the Base Indenture and
any reference in the Base Indenture to such Section 5.11 thereof shall be deemed to refer instead to this ‎Section 6.11. The
proviso set forth in Section 315(b) of the Trust Indenture Act shall not apply with respect to the Notes.

 

    	 	32	 

     

    

 

Section 6.12. Undertaking to Pay Costs.
All parties to the 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 the 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 6.12 (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 aggregate more than 10% in principal amount of the Notes at the time Outstanding determined in accordance with Section
7.04 of the Base Indenture, or to any suit instituted by any Holder for the enforcement of the payment of the principal
of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Redemption Price and the Fundamental
Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the
enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions
of ‎Article 14.

setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice
of such meeting within 20 days after receipt of such request, then the Issuer or such Holders may determine the time and the place

in ‎Section 9.02.

 

Section 9.04. Qualifications for Voting.

or counted at any meeting in respect of any Note challenged as not Outstanding and ruled by the chairman of the meeting to be not
Outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in

by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice

the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Issuer and the other to
the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

 

Any record so signed and verified shall
be conclusive evidence of the matters therein stated.

 

Section 9.07. No Delay of Rights by Meeting.
Nothing contained in this ‎Article 9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting
of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of
any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of the Indenture or

Upon the written request of the Issuer,
the Trustee is hereby authorized to join with the Issuer in the execution of any such supplemental indenture, to make any further
appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its
discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under the Indenture
or otherwise.

 

Any supplemental indenture authorized by
the provisions of this ‎Section 10.02 may be executed by the Issuer and the Trustee without the consent of the Holders of any
of the Notes at the time Outstanding, notwithstanding any of the provisions of ‎Section 10.03.

 

Section 10.03. Supplemental Indentures
with Consent of Holders. With the consent (evidenced as provided in Article
7 of the Base Indenture) of the Holders of at least a majority of the aggregate principal amount of the Notes then Outstanding
(determined in accordance with Article 7 of the Base Indenture
and including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes),
the Issuer, when authorized by the resolutions of the Board of Directors and the Trustee, at the Issuer’s expense, may from
time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying
in any manner the rights of the Holders; provided, however, that, without the consent of each Holder of an Outstanding
Note affected, no such supplemental indenture shall:

 

(a)          reduce
the amount of Notes whose Holders must consent to an amendment;

 

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

 

(c)          reduce
the principal of or extend the Maturity Date of any Note;

 

(d)          make
any change that adversely affects the conversion rights of any Notes;

 

(e)          reduce
the Redemption Price or the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the Holders
the Issuer’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions
or otherwise;

 

(f)           make
any Note payable in a currency other than that stated in the Note and in the Indenture or at a place of payment other than a place
located in the contiguous United States;

 

(g)          change
the ranking of the Notes in any manner adverse to Holders;

 

(h)          impair
the right of any Holder to receive payment of principal and interest on such Holder’s Notes on or after the due dates therefor
or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;

 

(i)           change
the provisions of Section 4.07 in any manner adverse to Holders; or

 

(j)           make

6.03 or ‎Section 6.10, except to increase any such percentage or to
provide that other provisions of the Indenture cannot be modified or waived without the consent of the Holders of each Outstanding
Note affected thereby.

 

    	 	37	 

     

    

 

Upon the written request of the Issuer,
and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to ‎Section 10.06, the
Trustee shall join with the Issuer in the execution of such supplemental indenture unless such supplemental indenture affects the
Trustee’s own rights, duties or immunities under the 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
10.03 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 Issuer shall mail 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 10.04. Effect of Supplemental
Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this ‎Article 10, the 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 the Indenture of the Trustee, the Issuer 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 the Indenture for any and all purposes.

 

Section 10.05. 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 Issuer’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Issuer 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 the Indenture contained in any such supplemental indenture may, at the Issuer’s
expense, be prepared and executed by the Issuer, authenticated 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 10.06. Evidence of Compliance
of Supplemental Indenture to Be Furnished to Trustee. In addition to the documents required by Section
11.05 of the Base Indenture, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this ‎Article 10 and is
permitted or authorized by the Indenture.

Consolidation, Merger, Sale, Conveyance and Lease

 

Section 11.01. Applicability of Article
9 of the Base Indenture.

 

(a)          Article
9 of the Base Indenture shall not apply to the Notes. Instead the provisions set forth in this ‎Article 11 shall, with respect
to the Notes, supersede in their entirety Article 9 of the Base Indenture, and all references in the Base Indenture to Article
9 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this
 ‎Article 11 or the applicable provisions set forth in this ‎Article 11, respectively.

 

Section 11.02. Issuer May Consolidate,
Etc. on Certain Terms. Subject to the provisions of ‎Section 11.03, the Issuer shall not consolidate with, merge with or
into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless:

 

(a)          the
resulting, surviving or transferee Person (the “Successor Company”), if not the Issuer, shall be (1) a corporation
organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, or (2) a
corporation or entity treated as a corporation for U.S. federal income tax purposes organized and validly existing under the laws
of the Islands of Bermuda, the Cayman Islands, Canada, Guernsey, Jersey, the Republic of Ireland, Luxembourg, the Netherlands,
Switzerland, France, Germany or the United Kingdom, and the Successor Company (if not the Issuer) shall expressly assume, by supplemental
indenture all of the obligations of the Issuer under the Notes and the Indenture (including, for the avoidance of doubt, the obligation
to pay Additional Amounts, as set forth in Section 4.07); and

 

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

 

For purposes of this ‎Section 11.02,
the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of
the Issuer to another Person, which properties and assets, if held by the Issuer instead of such Subsidiaries, would constitute
all or substantially all of the properties and assets of the Issuer on a consolidated basis, shall be deemed to be the sale, conveyance,
transfer or lease of all or substantially all of the properties and assets of the Issuer to another Person.

 

Section 11.03. Successor Company to Be
Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the
Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of
the due and punctual payment of the principal of and accrued and unpaid interest on all of the Notes, the due and 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 the Indenture to be performed by the Issuer, such Successor Company (if not the Issuer) shall
succeed to and, except in the case of a lease of all or substantially all of the Issuer’s properties and assets, shall be
substituted for the Issuer, with the same effect as if it had been initially named herein as the party. Such Successor Company
thereupon may cause to be signed, and may issue either in its own name or in the name of the Issuer any or all of the Notes issuable
hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such
Successor Company instead of the Issuer and subject to all the terms, conditions and limitations in the 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 Issuer to the Trustee for authentication, and any Notes that such Successor Company
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 the Indenture as the Notes theretofore or thereafter issued in accordance with the terms
of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation,
merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this ‎Article 11 the Person named
as the “Issuer” in the first paragraph of this Supplemental 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 the Indenture and the Notes.

 

    	 	39	 

     

    

 

In case of any such consolidation, merger,
sale, 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 11.04. Opinion of Counsel to
Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee
shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, 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. Conversion Privilege.
(a) Subject to and upon compliance with the provisions of this ‎Article 14, each Holder of a Note shall have the right, at
such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral
multiple thereof) of such Note (i) subject to satisfaction of the conditions described in ‎Section 14.01(b), at any time prior
to the close of business on the Business Day immediately preceding February 15, 2026 under the circumstances and during the periods
set forth in ‎Section 14.01(b), and (ii) regardless of the conditions described in ‎Section 14.01(b), on or after February
15, 2026 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial
conversion rate of 9.2123 shares of Common Stock (subject to adjustment as provided in this
‎Article 14, the “Conversion Rate”)
per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of ‎Section 14.02, the
 “Conversion Obligation”). Neither the Trustee nor the Conversion Agent (if other than the Trustee) shall have
any duty to determine or verify the Issuer’s determination of whether any of the conditions described in ‎‎Section
14.01(b) have been satisfied.

 

    	 	40	 

     

    

 

(b)          (i)
Prior to the close of business on the Business Day immediately preceding February 15, 2026, a Holder may surrender all or any portion
of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day
period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined
following a request by Holders of at least $1,000,000 principal amount of Notes in accordance with this subsection (b)(i), for
each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock
and the Conversion Rate on each such Trading Day. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant
to this subsection (b)(i) and the definition of Trading Price set forth in this Supplemental Indenture. The Issuer shall provide
written notice to the Bid Solicitation Agent (if other than the Issuer) of the three independent nationally recognized securities
dealers selected by the Issuer pursuant to the definition of Trading Price, along with appropriate contact information for each,
and shall direct such securities dealers to provide bids to the Bid Solicitation Agent (if other than the Issuer). The Bid Solicitation
Agent (if other than the Issuer) shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless
the Issuer has requested such determination, and the Issuer shall have no obligation to make such request (or, if the Issuer is
acting as Bid Solicitation Agent, the Issuer shall have no obligation to determine the Trading Price per $1,000 principal amount
of Notes) unless Holders of at least $1,000,000 principal amount of Notes provide the Issuer with reasonable evidence that the
Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the
Common Stock and the Conversion Rate for each Trading Day during the Measurement Period, at which time the Issuer shall instruct
the Bid Solicitation Agent (if other than the Issuer) to determine, or if the Issuer is acting as Bid Solicitation Agent, the Issuer
shall determine, the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive
Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the
Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Issuer is not acting as Bid Solicitation Agent,
and the Issuer does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes
when obligated as provided in the preceding sentence, or if the Issuer instructs the Bid Solicitation Agent to obtain bids and
the Bid Solicitation Agent fails to make such determination, or (y) the Issuer is acting as Bid Solicitation Agent and the Issuer
fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading Price
per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the
Common Stock and the Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been
met, the Issuer shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time
after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater
than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date,
the Issuer shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee).

 

    	 	41	 

     

    

 

(ii)          If,
prior to the close of business on the Business Day immediately preceding February 15, 2026, the Issuer elects to:

 

(A)         issue
to all or substantially all holders of the Common Stock any rights, options or warrants (other than any issuance of any rights,
options or warrants under a stockholder rights plan that are (x) transferable with shares of Common Stock, including shares of
Common Stock delivered upon conversion, and (y) not exercisable until the occurrence of a triggering event; provided that
such rights, options or warrants will be deemed issued under this subclause (A) upon the separation of such rights, options or
warrants from the Common Stock, or upon the occurrence of such triggering event) 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 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; or

 

(B)         distribute
to all or substantially all holders of the Common Stock the Issuer’s assets, securities (other than a distribution of the
Common Stock as to which an adjustment was effected pursuant to ‎Section 14.04(a)) or rights to purchase securities of the
Issuer (other than (x) rights described in the immediately preceding subclause (A) or (y) any issuance of any rights, options or
warrants issued under a stockholder rights plan that are (1) transferable with shares of Common Stock, including shares of Common
Stock delivered upon conversion, and (2) not exercisable until the occurrence of a triggering event), which distribution has a
per share value, as reasonably determined by the Board of Directors, exceeding 10% of the average of the Last Reported Sale Prices
of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding
the date of announcement for such distribution,

 

then, in either case, the Issuer shall notify all
Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 30 Scheduled Trading Days prior
to the Ex-Dividend Date for such issuance or distribution. Once the Issuer has given such notice, a Holder may surrender all or
any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately
preceding the Ex-Dividend Date for such issuance or distribution and (2) the Issuer’s announcement that such issuance or
distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time. Notwithstanding the
two immediately preceding sentences, Holders of the Notes will not be permitted to so surrender their Notes for conversion if such
Holders are entitled to participate (solely as a result of holding the Notes), at the same time and upon the same terms as holders
of the Common Stock, in such issuance or distribution without having to convert their Notes as if they held a number of shares
of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held
by such Holder.

 

    	 	42	 

     

    

 

(iii)         If
a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business
on the Business Day immediately preceding February 15, 2026, regardless of whether a Holder has the right to require the Issuer
to repurchase the Notes pursuant to ‎Section 15.02, or if the Issuer is a party to a Share Exchange Event (each such Fundamental
Change, Make-Whole Fundamental Change or Share Exchange Event, a “Corporate Event”), the Issuer shall notify
Holders, the Trustee and the Conversion Agent (if other than the Trustee) by mail or electronic delivery (such notice, a “Corporate
Event Notice”) as promptly as practicable following the date the Issuer publicly announces such Corporate Event or, in
the case that no public announcement is made, the occurrence of such Corporate Event. Upon receiving notice or otherwise becoming
aware of a transaction or event that would, if consummated, constitute a Corporate Event, the Issuer shall use commercially reasonable
efforts to announce or cause the announcement of such Corporate Event in time to deliver the related Corporate Event Notice at
least 30 Scheduled Trading Days prior to the anticipated effective date for such Corporate Event; provided that in no event
shall the Issuer be required to provide such Corporate Event Notice to the Holders before the earliest of such time as the Issuer
or its Affiliates (a) have publicly disclosed or acknowledged the circumstances giving rise to such Corporate Event, (b) are required
to publicly disclose under applicable law or the rules of any stock exchange on which the Common Stock is then listed the circumstances
giving rise to such Corporate Event and (c) have a reasonable basis to determine the anticipated effective date of such Corporate
Event. Upon the Issuer’s delivery of a Corporate Event Notice, a Holder may surrender all or a portion of its Notes for conversion
at any time until the 35th Trading Day immediately following the effective date of such Corporate Event or, if such Corporate Event
constitutes a Fundamental Change, the Business Day immediately preceding the related Fundamental Change Repurchase Date.

 

(iv)         Prior
to the close of business on the Business Day immediately preceding February 15, 2026, a Holder may surrender all or any portion
of its Notes for conversion at any time during any calendar quarter (and only during such calendar quarter) commencing after the
calendar quarter ending on June 30, 2019, if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether
or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately
preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day. The Issuer
shall determine at the beginning of each calendar quarter commencing after June 30, 2019 whether the Notes may be surrendered for
conversion in accordance with this clause ‎(iii) and shall notify the Holders, the Trustee and the Conversion Agent (if other
than the Trustee) by mail or electronic delivery if the Notes become convertible in accordance with this clause ‎(iii).

 

(v)          If
the Issuer calls any or all of the Notes for redemption pursuant to ‎Article 16 prior to 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
immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such time. After that time, the right
to convert on account of the Issuer’s delivery of a Redemption Notice shall expire, unless the Issuer 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.

Section 14.02. Conversion Procedure;
Settlement Upon Conversion.

 

(a)          Subject
to this ‎Section 14.02, ‎Section 14.03(b) and ‎Section 14.07(a), upon conversion of any Note, the Issuer 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 Common Stock, together with cash, if applicable, in lieu of delivering any
fractional share of Common Stock in accordance with subsection ‎(j) of this ‎Section 14.02 (“Physical Settlement”)
or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share
of Common Stock in accordance with subsection ‎(j) of this ‎Section 14.02 (“Combination Settlement”),
at its election, as set forth in this ‎Section 14.02.

 

(i)           All
conversions for which the relevant Conversion Date occurs on or after February 15, 2026, and all conversions for which the relevant
Conversion Date occurs after the Issuer’s issuance of a Redemption Notice with respect to the Notes and prior to the related
Redemption Date, shall be settled using the same Settlement Method.

 

(ii)          Except
for any conversions for which the relevant Conversion Date occurs after the Issuer’s issuance of a Redemption Notice with
respect to the Notes but prior to the related Redemption Date and any conversions for which the relevant Conversion Date occurs
on or after February 15, 2026, the Issuer shall use the same Settlement Method for all conversions with the same Conversion Date,
but the Issuer shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion
Dates.

 

(iii)         If,
in respect of any Conversion Date, the Issuer elects to deliver a notice (the “Settlement Notice”) of the relevant
Settlement Method in respect of such Conversion Date, the Issuer shall deliver such Settlement Notice in writing to the Holders
with a copy to 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 (x) after the date of issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date,
in such Redemption Notice or (y) on or after February 15, 2026, no later than February 15, 2026). If the Issuer does not elect
a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Issuer shall no longer have the
right to elect Cash Settlement or Physical Settlement with respect to such conversion and the Issuer 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 Issuer 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.

 

    	 	44	 

     

    

 

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

 

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

 

(B)         if
the Issuer elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Issuer 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 20 consecutive Trading Days during the related Observation Period; and

 

(C)         if
the Issuer elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination
Settlement, the Issuer 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 20 consecutive Trading Days during the related
Observation Period.

 

(v)         The
Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Issuer 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 Common Stock,
the Issuer 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 Common Stock.
The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

 

    	 	45	 

     

    

 

(b)          Subject
to ‎Section 14.02(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 14.02(h) and any taxes payable as described in ‎Section 14.02‎(d)
or ‎Section 14.02(e) (and therefore such Holder must allow for sufficient
time to comply with the Depositary’s procedures if such Holder wishes to exercise its conversion rights) 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 or by facsimile 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 Common Stock to be delivered upon
settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Issuer 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 14.02(h) and any taxes payable as described in ‎Section
14.02‎(d) or ‎Section 14.02(e). The Trustee (and if different, the Conversion Agent) shall notify the Issuer 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 Issuer 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 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 date (the “Conversion Date”)
that the Holder has complied with the requirements set forth in subsection ‎(b) above. Except as set forth in ‎Section
14.03(b) and ‎Section 14.07(a), the Issuer 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 relevant Conversion Date, if the Issuer elects Physical
Settlement (provided that for any Notes converted after the close of business on the Regular Record Date immediately preceding
the Maturity Date, the Issuer shall deliver the consideration due in respect of the Conversion Obligation on the Maturity Date),
or on the second Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement
Method. If any shares of Common Stock are due to converting Holders, the Issuer shall issue or cause to be issued, and deliver
to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through
the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Issuer’s
Conversion Obligation.

 

(d)          In
case any Note shall be surrendered for partial conversion, the Issuer shall execute and the Trustee shall authenticate and deliver
to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate
principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting
Holder but, if required by the Issuer 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 Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered
for such conversion.

 

    	 	46	 

     

    

 

(e)          If
a Holder submits a Note for conversion, the Issuer shall pay any documentary, stamp or similar issue or transfer tax due on the
issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests any 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 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 14.04, 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 Issuer shall notify the Trustee in writing
of any conversion of Notes effected through any Conversion Agent other than the Trustee.

 

(h)          Upon
conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below,
and the Issuer shall not adjust the Conversion Rate for any accrued and unpaid interest on any converted Notes. The Issuer’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 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 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 shall 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 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 Issuer has specified a Redemption Date that is after a Regular
Record Date and on or prior to the Business Day immediately following the date on which the corresponding interest payment is made;
(3) if the Issuer 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 date on which the corresponding interest payment is made; 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 or any Redemption Date shall receive the
full interest payment due on the Maturity Date or such Redemption Date, as applicable, regardless of whether their Notes have been
converted following such Regular Record Date.

 

    	 	47	 

     

    

 

(i)           The
Person in whose name any shares of Common Stock delivered upon conversion is registered shall be deemed to be the holder of record
of such shares as of the close of business on the relevant Conversion Date (in the case of Physical Settlement) or the last Trading
Day of the relevant Observation Period (in the case of 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 as of the time immediately prior to the close
of business on the Conversion Date.

 

(j)           The
Issuer 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 Issuer has elected (or is deemed to have
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 14.03. Increased Conversion Rate
Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.  (a) If a Make-Whole Fundamental
Change occurs or becomes effective prior to the Maturity Date and a Holder elects to convert its Notes in connection with such
Make-Whole Fundamental Change, the Issuer shall, under the circumstances described below, increase the Conversion Rate for the
Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”),
as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole
Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective
Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change
Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso
in subclause (x) of clause (b) 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”).

 

For the avoidance of doubt, if a Holder
converts its Notes and the Conversion Date is prior to the Effective Date of a Make-Whole Fundamental Change, then, whether or
not such Make-Whole Fundamental Change occurs, such Holder shall not be entitled to an increased Conversion Rate in connection
with such Make-Whole Fundamental Change.

 

(b)          Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to ‎Section 14.01(b)(iii), the
Issuer shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement
in accordance with ‎Section 14.02; provided, however, that if, at the effective time of a Make-Whole Fundamental
Change described in clause (b) 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 Stock 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 pursuant to
this ‎Section 14.03), multiplied by such Stock Price. In such event, the Conversion Obligation shall be determined and
paid to Holders in cash on the second Business Day following the Conversion Date. The Issuer shall notify the Trustee, the Conversion
Agent (if other than the Trustee) and the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change.

 

    	 	48	 

     

    

 

(c)          The
number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”)
and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole
Fundamental Change, which Stock Price will be the cash amount paid per share in a Make-Whole Fundamental Change described in clause
(b) of the definition of Fundamental Change if the Holders of Common Stock receive solely cash in exchange for the Common Stock.
Otherwise, the Stock Price for a Make-Whole Fundamental Change shall be the average of the Last Reported Sale Prices of the 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. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith
determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment
to the Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in ‎Section 14.04) or expiration date
of the event occurs during such five consecutive Trading Day period.

 

(d)          The
Stock 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 adjusted. The adjusted Stock Prices shall equal the Stock 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 Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares as set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set
forth in ‎Section 14.04.

 

(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 14.03 for each Stock Price and Effective Date set forth below:

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

 

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

 

(ii)         if
the Stock Price is greater than $750.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate;
and

 

(iii)        if
the Stock Price is less than $83.50 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

 

Notwithstanding the foregoing, in no event
shall the Conversion Rate per $1,000 principal amount of Notes exceed 11.9760 shares of Common Stock, subject to adjustment in
the same manner as the Conversion Rate pursuant to ‎Section 14.04.

 

(f)          Despite
the occurrence of a Make-Whole Fundamental Change, nothing in this ‎Section 14.03 shall prevent an adjustment to the Conversion
Rate pursuant to ‎Section 14.04 to the extent applicable.

 

Section 14.04. Adjustment of Conversion
Rate. The Conversion Rate shall be adjusted from time to time by the Issuer if any of the following events occurs, except that
the Issuer shall not make any adjustments to the Conversion Rate if Holders of the Notes 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 Common Stock and solely as a result of holding the Notes, in any of the transactions described in this ‎Section 14.04,
without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied
by the principal amount (expressed in thousands) of Notes held by such Holder.

 

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

 

 

 

where,

 

    	 	50	 

     

    

 

	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 share combination, as applicable;
	 	 	 
	CR'	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and
	 	 	 
	OS'	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 

Any adjustment made under this ‎Section 14.04(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 14.04(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 Issuer issues to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant
to a stockholder rights plan) 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 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 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 issuance;
	 	 	 
	CR'	=	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;

 

    	 	51	 

     

    

 

	X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
	 	 	 
	Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices 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 14.04(b) shall 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 such rights, options or warrants expire without delivery of
shares of Common Stock, the Conversion Rate shall be decreased 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 Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased
to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

 

For purposes of this ‎Section 14.04(b)
and for the purpose of ‎Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders
to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common
Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement
for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account
any consideration received by the Issuer 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 Issuer distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Issuer or rights,
options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock,
excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to ‎Section 14.04(a), ‎Section
14.04(b) or Section 14.04‎(e),
(ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to ‎Section 14.04(d),
and (iii) Spin-Offs as to which the specific provisions set forth below in this ‎Section 14.04(c) shall apply (any of such
shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital
Stock or other securities, the “Distributed Property”), 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;

 

    	 	52	 

     

    

 

	CR'	=	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 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; and
	 	 	 
	FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

 

Any increase made under the portion of this
 ‎Section 14.04(c) above shall 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 the Conversion Rate that would then be in
effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common
Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder
owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

 

With respect to an adjustment pursuant to
this ‎Section 14.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of
Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the
Issuer, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”),
the Conversion Rate shall instead be adjusted based on the following formula:

 

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
	 	 	 
	CR'	=	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 the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in ‎Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and

 

    	 	53	 

     

    

 

	MP0	=	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 

The adjustment to the Conversion Rate under the preceding paragraph
shall occur on the last Trading Day of the Valuation Period; provided that in respect of any conversion of Notes during
the Valuation Period, references in the portion of this ‎Section 14.04(c) related to Spin-Offs to a “10 consecutive Trading
Day period” shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the
Ex-Dividend Date of such Spin-Off to and including the Conversion Date in determining the Conversion Rate. If the Ex-Dividend Date
of the Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect
of a conversion of Notes, references in the preceding paragraph to a “10 consecutive Trading Day period” shall be deemed
to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and
including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period. 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 or make 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 purposes of this ‎Section 14.04(c)
(and subject in all respects to ‎Section 14.11), rights, options
or warrants distributed by the Issuer to all holders of the Common Stock entitling them to subscribe for or purchase shares of
the Issuer’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options
or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred
with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the
Common Stock, shall be deemed not to have been distributed for purposes of this ‎Section 14.04(c) (and no adjustment to the
Conversion Rate under this ‎Section 14.04(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 14.04(c). If any such right, option or warrant, including any such existing
rights, options or warrants distributed prior to the date of this Supplemental Indenture, are subject to events, upon the occurrence
of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other
assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend
Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall
be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any
distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described
in the immediately 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 14.04(c) was made, (1) in the case of any such rights, options
or warrants that 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 a holder or
holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options
or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights,
options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall
be readjusted as if such rights, options and warrants had not been issued.

 

    	 	54	 

     

    

 

For purposes of ‎Section 14.04(a),
 ‎Section 14.04(b) and this ‎Section 14.04(c), if any dividend
or distribution to which this ‎Section 14.04(c) is applicable also includes one or both of:

 

(A)         a
dividend or distribution of shares of Common Stock to which ‎Section 14.04(a) is applicable (the “Clause A Distribution”);
or

 

(B)         a
dividend or distribution of rights, options or warrants to which ‎Section 14.04(b) is applicable (the “Clause B Distribution”),

 

then, in either case, (1) 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 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment
required by this ‎Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution
and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required
by ‎Section 14.04(a) and ‎Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Issuer
(I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend
Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution
shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date”
within the meaning of ‎Section 14.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend
Date” within the meaning of ‎Section 14.04(b).

 

(d)          If
any cash dividend or distribution is made to all or substantially all holders of the Common Stock (other than a distribution as
to which an adjustment to the Conversion Rate was effected pursuant to ‎Section 14.04‎(e)),
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;
	 	 	 
	CR'	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

 

    	 	55	 

     

    

 

	SP0	=	the Last Reported Sale Price of the 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 the Issuer distributes to all or substantially all holders of the Common Stock.

 

Any increase to the Conversion Rate pursuant
to this ‎Section 14.04(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 be the Conversion Rate that would then be
in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined
above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder
of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares
of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common
Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution.

 

(e)          If
the Issuer or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of
the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the
Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer,
the Conversion Rate shall be increased based on the following formula:

 

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	 	 	 
	CR'	=	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
	 	 	 
	AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
	 	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

 

    	 	56	 

     

    

 

	OS'	=	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
	 	 	 
	SP'	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.

 

The increase to the Conversion Rate under this ‎Section
14.04(e) shall occur at the close of business on the 10th Trading
Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided
that in respect of any conversion of Notes within the 10 Trading Days immediately following, and including, the Trading Day next
succeeding the date such tender or exchange offer expires, references in this ‎Section 14.04(e) with respect to “10”
or “10th” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such
tender or exchange offer expires and the Conversion Date in determining the Conversion Rate. In addition, if the Trading Day next
succeeding the date such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the
end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph to “10” or
 “10th” shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading
Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and
including, the last Trading Day of such Observation Period. If the Issuer or one of its Subsidiaries is obligated to purchase Common
Stock pursuant to any such tender or exchange offer but the Issuer, or such Subsidiary, is permanently prevented by applicable
law from effecting any such purchase or all such purchases are rescinded, the Conversion Rate shall be decreased to the Conversion
Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases
that have been effected.

 

(f)          Notwithstanding
this ‎Section 14.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective
on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related
Record Date would be deemed to be the record holder of the shares of Common Stock as of the related Conversion Date as described
under ‎Section 14.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion
Rate adjustment provisions in this ‎Section 14.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not
be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares
of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such
adjustment.

 

(g)          Except
as stated herein, the Issuer 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.

 

    	 	57	 

     

    

 

(h)          In
addition to those adjustments required by clauses ‎(a), ‎(b), ‎(c), ‎(d) and ‎(e) of this ‎Section 14.04,
and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Issuer’s
securities are then listed, the Issuer from time to time may increase the Conversion Rate 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 Issuer’s best interest. In addition,
to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Issuer’s
securities are then listed, the Issuer may (but is not required to) increase the Conversion Rate to avoid or diminish any income
tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common
Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either
of the preceding two sentences, the Issuer shall mail to the Holder of each Note at its last address appearing on the Security
Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice
shall state the increased Conversion Rate and the period during which it will be in effect.

 

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

 

(i)          upon
the sale by the Issuer of shares of Common Stock at a price below the Conversion Price or otherwise;

 

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

 

(iii)        upon
the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee,
director or consultant benefit plan or program of or assumed by the Issuer or any of the Issuer’s 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 clause ‎(iii) of this subsection and outstanding as of the date the Notes were first issued or, in
the case of notes, bonds or debentures that are convertible into shares of Common Stock, issued after the date the Notes were first
issued (other than any such issuance described in ‎Section 14.04‎(c)
or ‎Section 14.04‎(e)
above for which an adjustment shall be made pursuant to such provisions);

 

(v)         for
a third-party tender offer by any party other than a tender offer by one or more of the Issuer’s Subsidiaries as described
in ‎Section 14.04‎(e)
above;

 

(vi)        upon
the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program (including pursuant to structured
or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives) or other buy-back
transaction, in each case that does not constitute a tender offer as described in ‎Section
14.04‎(e) above;

 

    	 	58	 

     

    

 

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

 

(viii)      for
accrued and unpaid interest, if any.

 

(j)          Notwithstanding
anything to the contrary in the Indenture, the Issuer shall not be required to make an adjustment pursuant to clauses ‎(a),
 ‎(b), ‎(c), ‎(d) or ‎(e) of this ‎Section 14.04 unless such adjustment would result in a change of at least
1% in the then-effective Conversion Rate. However, the Issuer shall carry forward any adjustment that is less than 1% of the Conversion
Rate and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward
adjustments shall be made upon the earliest to occur of the following: (1) when all such carried-forward adjustments would result
in an aggregate change of at least 1% to the Conversion Rate, (2) (x) the Conversion Date for any Notes (in the case of Physical
Settlement) and (y) each Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement), (3)
the effective date of any Fundamental Change or Make-Whole Fundamental Change and (4) February 15, 2026. All calculations and other
determinations under this ‎Article 14 shall be made by the Issuer and shall be made to the nearest one-ten thousandth (1/10,000th)
of a share.

 

(k)          Whenever
the Conversion Rate is adjusted as herein provided, the Issuer shall promptly file with the Trustee (and the Conversion Agent if
not the Trustee) an Officer’s 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
Officer’s 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. Promptly after delivery of such
certificate, the Issuer shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion
Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate
to each Holder at its last address appearing on the Security Register. Failure to deliver such notice shall not affect the legality
or validity of any such adjustment.

 

(l)          For
purposes of this ‎Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common
Stock held in the treasury of the Issuer so long as the Issuer does not pay any dividend or make any distribution on shares of
Common Stock held in the treasury of the Issuer, but shall include shares of Common Stock issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock.

 

(m)          The
Issuer or the Paying Agent may deduct withholding taxes due with respect to the Notes from payments of cash and Common Stock on
the Notes. In the case of any such amounts withheld from Common Stock delivered upon conversion of the Notes, such Common Stock
shall be valued based on the arithmetic average of the Daily VWAP for each Trading Day in the relevant Observation Period.

 

Section 14.05. Adjustments of Prices. Whenever any provision
of the Indenture requires the Issuer to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock
Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account
for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where
the Ex-Dividend Date, Effective Date (as such term is used in ‎Section 14.04) or expiration date of the event occurs, at any
time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement
Amounts are to be calculated.

 

    	 	59	 

     

    

 

Section 14.06. Shares to Be Fully Paid.
The Issuer shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient
shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming
delivery of the maximum number of Additional Shares pursuant to ‎Section 14.03 and that at the time of computation of such
number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

 

Section 14.07. Effect of Recapitalizations,
Reclassifications and Changes of the Common Stock.

 

(a)          In
the case of:

 

(i)          any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

 

(ii)         any
consolidation, merger or combination involving the Issuer,

 

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

 

(iv)        any
statutory share exchange or any similar transaction,

 

in each case, as a result of which the 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 “Share Exchange Event”), then, at and after the effective time of such Share Exchange
Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount
of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination
thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Share Exchange
Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference
Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to
receive) upon such Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Issuer or the
successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under ‎Section
10.02(k) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however,
that at and after the effective time of the Share Exchange Event (A) the Issuer (or, if applicable, any successor to the Issuer)
shall have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes
in accordance with ‎Section 14.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with ‎Section
14.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Issuer would have been required to deliver
upon conversion of the Notes in accordance with ‎Section 14.02 shall instead be deliverable in the amount and type of Reference
Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Share Exchange Event
and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

 

    	 	60	 

     

    

 

If the Share Exchange Event causes the Common
Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in
part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be
deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock, and
(ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred
to in clause (i) attributable to one share of Common Stock. If the holders of the Common Stock receive only cash in such Share
Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange
Event (A) the consideration due upon conversion of each $1,000 principal 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
14.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (B) the Issuer shall satisfy
the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant Conversion
Date. The Issuer shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average
as soon as practicable after such determination is made.

 

Such supplemental indenture described in
the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent
as reasonably practicable (as determined by the Issuer in good faith) to the adjustments provided for in this ‎Article 14.
If, in the case of any Share Exchange Event, the Reference Property 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 corporation, as the case may be,
in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person and shall contain such
additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider
necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in ‎Article 15.

 

(b)          When
the Issuer executes a supplemental indenture pursuant to subsection ‎(a) of this ‎Section 14.07, the Issuer shall promptly
file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities
or property or asset that will comprise a unit of Reference Property after any such Share Exchange Event, any adjustment to be
made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to
all Holders. The Issuer shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at its
address appearing on the Security Register provided for in the Indenture, within 20 days after execution thereof. Failure to deliver
such notice shall not affect the legality or validity of such supplemental indenture.

 

    	 	61	 

     

    

 

(c)          The
Issuer shall not become a party to any Share Exchange Event unless its terms are consistent with this ‎Section 14.07. None
of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into cash, shares of Common Stock
or a combination of cash and shares of Common Stock, as applicable, as set forth in ‎Section 14.01 and ‎Section 14.02 prior
to the effective date of such Share Exchange Event.

 

(d)          The
above provisions of this Section shall similarly apply to successive Share Exchange Events.

 

Section 14.08. Certain Covenants.
(a) The Issuer covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable
by the Issuer and free from all taxes, liens, charges and preemptive rights with respect to the issue thereof.

 

(b)          The
Issuer covenants that, if any shares of 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 Common Stock may be validly
issued upon conversion, the Issuer 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
Issuer further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated
quotation system the Issuer will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated
quotation system, any Common Stock issuable upon conversion of the Notes.

 

Section 14.09. Responsibility of Trustee.
The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine
the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase)
of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect
to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. 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 Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any
Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Issuer to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Issuer contained in this Article. Neither the Trustee nor any other
Conversion Agent shall have any duty or responsibility whatsoever to determine compliance with the conversion procedures, or to
make or confirm any calculations with respect to the settlement provisions, of ‎Section 14.02. Without limiting the generality
of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture entered into pursuant to ‎Section 14.07 relating either to the kind
or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes
after any event referred to in such ‎Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 6.02 of the Base Indenture, may accept (without
any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officer’s Certificate (which the Issuer shall be obligated to file with the Trustee prior to the execution of any
such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining
whether any event contemplated by ‎Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer
eligible therefor until the Issuer has delivered to the Trustee and the Conversion Agent the notices referred to in ‎Section
14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion
Agent may conclusively rely, and the Issuer agrees to deliver such notices to the Trustee and the Conversion Agent immediately
after the occurrence of any such event or at such other times as shall be provided for in ‎Section 14.01(b). The rights, benefits
and privileges of the Trustee set forth in the Base Indenture shall be applicable to the Conversion Agent, and the provisions set
forth in Section 6.01 of the Base Indenture relating to the Trustee shall apply to the Conversion Agent.

 

    	 	62	 

     

    

 

Section 14.10. Notice to Holders Prior
to Certain Actions. In case of any:

 

(a)          action
by the Issuer or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to ‎Section 14.04
or ‎Section
14.11;

 

(b)          Share
Exchange Event; or

 

(c)          voluntary
or involuntary dissolution, liquidation or winding-up of the Issuer or any of its Subsidiaries;

 

then, in each case (unless notice of such event is otherwise
required pursuant to another provision of the Indenture), the Issuer shall cause to be filed with the Trustee and the Conversion
Agent (if other than the Trustee) and to be mailed (or delivered electronically in accordance with the procedures of the Depositary
in the case of Global Notes) to each Holder at its address appearing on the Security Register, as promptly as possible but in any
event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to
be taken for the purpose of such action by the Issuer or one of its Subsidiaries or, if a record is not to be taken, the date as
of which the holders of Common Stock of record are to be determined for the purposes of such action by the Issuer or one of its
Subsidiaries, or (ii) the date on which such Share Exchange Event, dissolution, liquidation or winding-up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange
their Common Stock for securities or other property deliverable upon such Share Exchange Event, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Issuer or one
of its Subsidiaries, Share Exchange Event, dissolution, liquidation or winding-up.

 

Section 14.11. Stockholder Rights Plans.
If the Issuer has a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued
upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the
Common Stock issued upon such conversion shall bear such legends, if any, in each case, as may be provided by the terms of any
such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the
rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan,
the Conversion Rate shall be adjusted at the time of separation as if the Issuer distributed to all or substantially all holders
of the Common Stock Distributed Property as provided in ‎Section 14.04(c), subject to readjustment in the event of the expiration,
termination or redemption of such rights.

 

Section 14.12. Exchange in Lieu of Conversion.

 

    	 	63	 

     

    

 

(a)          Notwithstanding
any other provision of this Article 14, when a Holder surrenders a Note for conversion and the Conversion Date for such Note occurs
prior to February 15, 2026, the Issuer may, at its election, direct the Conversion Agent to surrender, on or prior to the Scheduled
Trading Day immediately preceding the first Trading Day of the applicable Observation Period (or if the Issuer has elected Physical
Settlement, on or prior to the Business Day immediately following the relevant Conversion Date), such Note to a financial institution
designated by the Issuer for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated
financial institution must agree to pay and/or deliver, as the case may be, in exchange for such Notes, all of the cash, shares
of Common Stock or a combination thereof due upon conversion, all in accordance with Section 14.02. By the close of business on
the Scheduled Trading Day immediately preceding the first Trading Day of the applicable Observation Period (or, if the Issuer has
elected Physical Settlement, by the close of business on the Business Day immediately following the relevant Conversion Date),
the Issuer shall notify the Holder surrendering Notes for conversion that the Issuer has directed the designated financial institution
to make an exchange in lieu of conversion.

 

(b)          If
the designated financial institution accepts any such Notes, it will pay and/or deliver, as the case may be, the cash, shares of
Common Stock or a combination thereof due upon conversion to the Conversion Agent, and the Conversion Agent shall pay and/or deliver
such cash and/or shares of Common Stock to such Holder on the second Business Day immediately following the last Trading Day of
the applicable Observation Period (or, if the Issuer has elected Physical Settlement, on the second Business Day immediately following
the relevant Conversion Date). Any Notes exchanged by the designated financial institution will remain outstanding, subject to
the applicable procedures of the Depositary. If the designated financial institution agrees to accept any Notes for exchange but
does not timely pay and/or deliver the related cash, shares of Common Stock or a combination thereof, as the case may be, or if
such designated financial institution does not accept the Notes for exchange, the Issuer shall convert the Notes and pay and/or
deliver, as the case may be, the cash, shares of Common Stock or a combination thereof due upon conversion on the second Business
Day immediately following the last Trading Day of the applicable Observation Period (or, if the Issuer has elected Physical Settlement,
on the second Business Day immediately following the relevant Conversion Date) as set forth in Section 14.02. The Issuer’s
designation of a financial institution to which the Notes may be submitted for exchange does not require the financial institution
to accept any Notes (unless the financial institution has separately made an agreement with the Issuer to do so). The Issuer may,
but will not be obligated to, enter into a separate agreement with any designated financial institution that would compensate it
for any such transaction.

Section 15.01. Intentionally Omitted.

 

    	 	64	 

     

    

 

Section 15.02. Repurchase at Option of
Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time, each Holder shall have the right, at such
Holder’s option, to require the Issuer to repurchase for cash all of such Holder’s Notes, or any portion thereof that
is equal to $1,000 or an integral multiple of $1,000 in excess thereof, on the date (the “Fundamental Change Repurchase
Date”) specified by the Issuer that is not less than 20 calendar days or more than 35 calendar days following the date
of the Fundamental Change Issuer Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued
and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase
Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest
Payment Date to which such Regular Record Date relates, in which case the Issuer shall instead pay the full amount of accrued and
unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal
to 100% of the principal amount of Notes to be repurchased pursuant to this ‎Article 15. The Fundamental Change Repurchase
Date shall be subject to postponement to the extent required by applicable tender offer rules under the Exchange Act.

 

(b)          Repurchases
of Notes under this ‎Section 15.02 shall be made, at the option of the Holder thereof, upon:

 

(i)          delivery
to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the
form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance
with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case
prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

 

(ii)         delivery
of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental Change Repurchase
Notice (together with all necessary endorsements for transfer) at the address set forth in the Fundamental Change Issuer Notice,
or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each
case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

 

The Fundamental Change Repurchase Notice
in respect of any Notes to be repurchased shall state:

 

(i)          in
the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

 

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

 

(iii)        that
the Notes are to be repurchased by the Issuer pursuant to the applicable provisions of the Notes and the Indenture;

 

provided, however, that if the Notes are Global
Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

 

    	 	65	 

     

    

 

Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this ‎Section 15.02 shall
have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business
on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal
to the Paying Agent in accordance with ‎Section 15.03.

 

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

 

(c)          On
or before the 20th calendar day after the occurrence of the effective date of a Fundamental Change, the Issuer shall provide to
all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the
 “Fundamental Change Issuer Notice”) of the occurrence of the effective date of the Fundamental Change and of
the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall
be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures
of the Depositary. Each Fundamental Change Issuer 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 may exercise the repurchase right pursuant to this ‎Article 15;

 

(iv)        the
Fundamental Change Repurchase Price;

 

(v)         the
Fundamental Change Repurchase Date (which may be subject to postponement by the Issuer to the extent required by applicable tender
offer rules under the Exchange Act);

 

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

 

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

 

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

 

(ix)         the
procedures that Holders must follow to require the Issuer to repurchase their Notes.

 

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

 

    	 	66	 

     

    

 

At the Issuer’s written request given
at least two Business Days in advance, the Trustee shall give such notice in the Issuer’s name and at the Issuer’s
expense; provided, however, that, in all cases, the text of such Fundamental Change Issuer Notice shall be prepared
by the Issuer.

 

(d)          Notwithstanding
the foregoing, no Notes may be repurchased by the Issuer on any date at the option of the Holders upon a Fundamental Change if
the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date
(except in the case of an acceleration resulting from a Default by the Issuer in the payment of the Fundamental Change Repurchase
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 Issuer in the
payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of
the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or
cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

 

(e)          Notwithstanding
the foregoing, the Issuer shall not be required to repurchase, or to make an offer to repurchase, the Notes upon a Fundamental
Change if (i) a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements
for an offer made by the Issuer as set forth in this ‎Article 15 and (ii) such third party purchases all of the Notes validly
surrendered and not validly withdrawn under such offer in the same manner, at the same time and otherwise in compliance with the
requirements for an offer made by the Issuer as set forth in this ‎Article 15.

 

Section 15.03. Withdrawal of Fundamental
Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written
notice of withdrawal delivered to the Paying Agent at the address set forth in the Fundamental Change Issuer Notice in accordance
with this ‎Section 15.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental
Change Repurchase Date, specifying:

 

(i)          the
principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which portion must be in principal
amounts of $1,000 or an integral multiple of $1,000,

 

(ii)         if
Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted,
and

 

(iii)        the
principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion
must be in principal amounts of $1,000 or an integral multiple of $1,000;

 

provided, however, that if the Notes are Global
Notes, the notice must comply with appropriate procedures of the Depositary.

 

    	 	67	 

     

    

 

Section 15.04. Deposit of Fundamental
Change Repurchase Price. (a) The Issuer shall deposit with the Paying Agent (or if the Issuer is acting as its own Paying Agent,
set aside, segregate and hold in trust as provided in Section 3.04 of
the Base Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of
money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject
to receipt of funds and/or Notes by the Paying Agent, payment for Notes surrendered for repurchase (and not withdrawn prior to
the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date) will be made on the later
of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions in ‎Section 15.02) and
(ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Issuer)
by the Holder thereof in the manner required by ‎Section 15.02 by mailing checks for the amount payable to the Holders of such
Notes entitled thereto as they shall appear in the Security Register; provided, however, that payments to the Depositary
shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee, in accordance with
the procedures of the Depositary. The Paying Agent shall, promptly after such payment and upon written demand by the Issuer, return
to the Issuer any funds in excess of the Fundamental Change Repurchase Price.

 

(b)          If
by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Paying Agent holds money sufficient to make payment
on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then, with respect
to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn, (i) such Notes shall cease
to be Outstanding, (ii) interest shall cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been
made or the Notes have been delivered to the Paying Agent) and (iii) all other rights of the Holders of such Notes shall terminate
(other than the right to receive the Fundamental Change Repurchase Price).

 

(c)          Upon
surrender of a Note that is to be repurchased in part pursuant to ‎Section 15.02, the Issuer shall execute and the Trustee
shall upon the receipt of an Officer’s Certificate, an Issuer Order and an Opinion of Counsel, authenticate and deliver to
the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

 

Section 15.05. Covenant to Comply
with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer, the Issuer shall, if required:

 

(a)          comply
in all material respects with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act;

 

(b)          file
a Schedule TO or any other required schedule under the Exchange Act; and

 

(c)          otherwise
comply in all material respects with all federal and state securities laws in connection with any offer by the Issuer to repurchase
the Notes;

 

in each case, so as to permit the rights and
obligations under this ‎Article 15 to be exercised in the time and in the manner specified in this ‎Article 15.

Optional Redemption

 

Section 16.01. Applicability of Article
12 of the Base Indenture. Article 12 of the Base Indenture shall not apply to the Notes. Instead the provisions set forth in
this ‎Article 16 shall, with respect to the Notes, supersede in its entirety Article 12 of the Base Indenture, and all references
in the Base Indenture to Article 12 thereof and the provisions therein, as the case may be, shall, with respect to the Notes, be
deemed to be references to this ‎Article 16 or the applicable provisions set forth in this ‎Article 16, respectively.

 

Section 16.02. Optional Redemption.
No sinking fund is provided for the Notes. The Notes shall not be redeemable by the Issuer prior to May 20, 2023. On or after
May 20, 2023, the Issuer may redeem (an “Optional Redemption”) for cash all or part of the Notes, at the Redemption
Price, if the Last Reported Sale Price 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 Issuer provides the Redemption
Notice in accordance with ‎Section 16.03.

 

Section 16.03. Notice of Optional
Redemption; Selection of Notes. (a) In case the Issuer exercises its Optional Redemption right to redeem all or, as the case
may be, any part of the Notes pursuant to ‎Section 16.02, it shall fix a date for redemption (each, a “Redemption
Date”) and it or, at its written request received by the Trustee not less than 45 calendar days prior to the Redemption
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
Issuer, shall provide notice of such Optional Redemption (a “Redemption Notice”) not less than 35 nor more than
60 calendar days prior to the Redemption Date by mail or electronic delivery to each Holder of Notes so to be redeemed as a whole
or in part at its last address as the same appears on the Note Register; provided, however, that, if the Issuer 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.

 

(b)          The
Redemption 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 Redemption Notice by mail 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;

 

(ii)         the
Redemption Price;

 

(iii)        that on
the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that interest thereon,
if any, shall cease to accrue on and after the Redemption Date;

 

    	 	69	 

     

    

 

(iv)        the
place or places where such Notes are to be surrendered for payment of the Redemption Price;

 

(v)         that
Holders may surrender their Notes for conversion at any time prior to the close of business on the Scheduled Trading Day immediately
preceding the Redemption Date;

 

(vi)        the
procedures a converting Holder must follow to convert its Notes and the Settlement Method and Specified Cash Amount, if applicable;

 

(vii)       the
Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with ‎Section
14.03;

 

(viii)      the
CUSIP, ISIN or other similar numbers, if any, assigned to such Notes; and

 

(ix)         in
case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and on and after the 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
fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of a Global
Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro
rata basis or by another method the Trustee considers to be fair and appropriate. 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.

 

(e)          In
the event of any redemption in part, the Issuer shall not be required to register the transfer of or exchange any Note so selected
for redemption, in whole or in part, except the unredeemed portion of any Note being redeemed in part.

 

Section 16.04. Payment of Notes
Called for Redemption. (a) If any Redemption Notice has been given in respect of the Notes in accordance with ‎Section
16.03, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and
at the applicable Redemption Price. On presentation and surrender of the Notes at the place or places stated in the Redemption
Notice, the Notes shall be paid and redeemed by the Issuer at the applicable Redemption Price.

 

(b)          Prior
to the open of business on the Redemption Date, the Issuer shall deposit with the Paying Agent or, if the Issuer or a Subsidiary
of the Issuer is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 6.05 of the Base Indenture
an amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price
of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes
to be redeemed shall be made on the Redemption Date for such Notes. The Paying Agent shall, promptly after such payment and upon
written demand by the Issuer, return to the Issuer any funds in excess of the Redemption Price.

 

    	 	70	 

     

    

 

Section 16.05. Restrictions on
Redemption. The Issuer may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance
with the terms of the Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the
case of an acceleration resulting from a Default by the Issuer in the payment of the Redemption Price with respect to such Notes).

Section 17.04. Legal Holidays. In
any case where any Interest Payment Date, Fundamental Change Repurchase Date or Maturity Date is not a Business Day, then any action
to be taken on such date need not be taken on such date, but may be taken on the next succeeding Business Day with the same force

Section 17.05. No Security Interest Created.
Nothing in the Indenture or in the Notes, expressed or implied, shall be construed to constitute a security interest under the
Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction.

 

Section 17.06. Benefits of Indenture.
Nothing in the Indenture or in the Notes, expressed or implied, shall give or be construed to give to any Person, other than the

condition or provision contained in the Indenture; all such covenants, conditions and provisions being for the sole benefit of
the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Security Registrar and their successors
and of the Holders of the Notes.

 

Section 17.07. Table of Contents, Headings,
Etc. The article and section headings and the table of contents in this Supplemental Indenture are for convenience only and

Section 17.08. 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 2.05, Section
2.06, Section 2.09 and Section
2.11 of the Base Indenture and ‎Section 10.05 and ‎Section
15.04 of this Supplemental Indenture as fully to all intents and purposes as though the authenticating agent had been expressly
authorized by the Indenture and those Sections to authenticate and deliver Notes. For all purposes of the 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
6.09 of the Base Indenture.

 

    	 	72	 

     

    

 

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 the corporate trust business of any authenticating agent, shall be the successor of the authenticating agent hereunder,
if such successor corporation or other entity is otherwise eligible under this ‎Section 17.08, 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 corporation or
other entity.

 

Any authenticating agent may at any time
resign by giving written notice of resignation to the Trustee and to the Issuer. 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 Issuer. 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, the Trustee may appoint a successor authenticating agent (which may be the Trustee), shall give written notice
of such appointment to the Issuer and shall mail notice of such appointment to all Holders as the names and addresses of such Holders
appear on the Note Register.

 

The Issuer agrees to pay to the authenticating
agent from time to time reasonable compensation for its services although the Issuer may terminate the authenticating agent, if
it determines such agent’s fees to be unreasonable.

 

The provisions of Section
6.03, Section 6.04, Section 6.06, Section
6.07 and Section 7.03 of the Base Indenture and this ‎Section 17.08 shall be applicable to any authenticating agent.

pursuant to this ‎Section 17.08, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication,
an alternative certificate of authentication in the following form:

 

__________________________,

as Authenticating Agent, certifies that this is one of the Notes described

in the within-named Indenture.

 

By:_______________________,

Authorized Officer  

 

Section 17.09. Execution in Counterparts.
This Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original; but such counterparts
shall together constitute but one and the same instrument. The exchange of copies of this Supplemental Indenture and of signature
pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the
parties hereto and may be used in lieu of an original Supplemental Indenture for all purposes. Signatures of the parties hereto
transmitted by facsimile or PDF transmission shall be deemed to be their original signatures for all purposes.

Section 17.10. Separability. In case
any one or more of the provisions contained in this Supplemental Indenture or in the Notes shall for any reason be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions
of this Supplemental Indenture or of the Notes, but this Supplemental Indenture and the Notes shall be construed as if such invalid
or illegal or unenforceable provision had never been contained herein or therein.

 

Section 17.11. Waiver of Jury Trial.
EACH OF THE ISSUER 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 SUPPLEMENTAL INDENTURE, THE NOTES OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

 

Section 17.12. 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, 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 17.13. Calculations. Except
as otherwise provided herein, the Issuer shall be responsible for making all calculations called for under the Notes. These calculations
include, but are not limited to, determinations of the Stock Price, the Last Reported Sale Prices of the Common Stock, the Daily
VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes, any Additional Interest
payable on the Notes and the Conversion Rate of the Notes. The Issuer shall make all these calculations in good faith and, absent
manifest error, the Issuer’s calculations shall be final and binding on Holders of Notes. The Issuer 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 Issuer’s calculations without independent verification. The Trustee shall forward
the Issuer’s calculations to any Holder of Notes upon the request of that Holder at the sole cost and expense of the Issuer.

 

Section 17.14. No Personal Liability
of Directors, Officers, Employees and Stockholders. No past, present or future director, officer, employee, incorporator or
stockholder of the Issuer, as such, will have any liability for any obligations of the Issuer under the Indenture or the Notes
or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting any Note, each Holder
waives and releases all such liability, and such waiver and release are part of the consideration for the issuance of Notes.

 

Section 17.15. 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 the 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 17.16. Ratification of Base
Indenture.

 

(a)          Except
as amended hereby with respect to the Notes, the Base Indenture, as amended and supplemented by this Supplemental Indenture, is
in all respects ratified and confirmed, and this Supplemental Indenture shall be deemed part of the Base Indenture in the manner
and to the extent herein and therein provided.

the next scheduled Interest Payment Date until May 15, 2026. Interest is payable semi-annually in arrears on each May 15 and November

[FORM OF REVERSE OF NOTE]

 

INTERCEPT PHARMACEUTICALS, INC.

2.00% Convertible Senior Note due 2026

 

This Note is one of a duly authorized issue
of Notes of the Issuer, designated as its 2.00% Convertible Senior Notes due 2026 (the “Notes”), limited to
the aggregate principal amount of $230,000,000, all issued or to be issued under and pursuant to an Indenture dated as of July
6, 2016 (the “Base Indenture”), as amended and supplemented by the Second Supplemental Indenture dated as of
May 14, 2019 (herein called the “Supplemental Indenture”; the Base Indenture, as amended and supplemented by
the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the “Indenture”),
by and between the Issuer 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 Issuer 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 Issuer will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental
Change Repurchase Date or the Redemption Price on any Redemption Date (if applicable) 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 Issuer shall 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 Issuer 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 Issuer, which is absolute and unconditional,
to pay or deliver, as the case may be, the principal (including the Redemption Price and the Fundamental Change Repurchase 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 or shares of Common Stock, as the case may be, herein prescribed.

 

     A-5

     

    

 

The Notes are issuable in registered form
without coupons in minimum denominations of $1,000 principal amount and multiples of $1,000 in excess thereof. At the office or
agency of the Issuer 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 Issuer 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 Issuer’s
option on or after May 20, 2023 in accordance with the terms and subject to the 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 Issuer to repurchase for cash all of such Holder’s
Notes or any portion thereof (in principal amounts of $1,000 or multiples of $1,000 in excess thereof) on the Fundamental Change
Repurchase Date at a price equal to the Fundamental Change Repurchase 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 Business Day immediately preceding the Maturity Date, to convert any Notes
or portion thereof that is $1,000 or a multiple thereof, into cash, shares of Common Stock or a combination of cash and shares
of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in
the Indenture.
