​
DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934
​
General
​
Catalyst Bancorp, Inc. (“Catalyst” or, the “Company”) is authorized to issue 35,000,000 shares of capital stock, of which 30,000,000 are shares of common stock, par value $.01 per share, and 5,000,000 are shares of serial preferred stock, par value $.01 per share. As of December 31, 2021, there were 5,290,000 shares of Company common stock issued and outstanding and no shares of Company preferred stock issued and outstanding. The Company’s common stock is registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended, and is listed on the Nasdaq Capital Market under the symbol “CLST”.
​
The following description of our common stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to our articles of incorporation and bylaws, each of which is incorporated by reference as an exhibit to the Annual Report on Form 10-K of which this Exhibit 4.1 is a part, and to applicable provisions of law.
​
Common Stock
​
Dividends.  Catalyst can pay dividends if, as and when declared by its board of directors, subject to compliance with limitations which are imposed by law. The holders of our common stock are entitled to receive and share equally in such dividends as may be declared by our board of directors out of funds legally available therefor. If we issue preferred stock, the holders thereof may have a priority over the holders of the common stock with respect to dividends.
​
Voting Rights.  The holders of our common stock possess exclusive voting rights in Catalyst. They elect our board of directors and act on such other matters as are required to be presented to them under Louisiana law or our articles of incorporation or as are otherwise presented to them by the board of directors. Except as discussed below under “Restrictions on Acquisitions of Catalyst and Related Anti-Takeover Provisions,” each holder of common stock is entitled to one vote per share and does not have any right to cumulate votes in the election of directors. If we issue preferred stock, holders of the preferred stock may also possess voting rights.
​
Liquidation.  In the event of any liquidation, dissolution or winding up of Catalyst, the holders of our common stock would be entitled to receive, after payment or provision for payment of all our debts and liabilities, (including payments with respect to the liquidation account of Catalyst) all of the assets of Catalyst available for distribution.
​
Preemptive Rights.  Holders of our common stock are not entitled to preemptive rights with respect to any shares which may be issued in the future. Our common stock is not subject to any required redemption.
​
Preferred Stock
​
Our authorized preferred stock may be issued with such preferences and designations as the board of directors may from time to time determine. Our board of directors can, without shareholder approval, issue preferred stock with voting, dividend, liquidation and conversion rights which could dilute the voting strength of the holders of the common stock and may assist management in impeding an unfriendly takeover or attempted change in control.
​
Restrictions on Acquisitions of Catalyst and Related Anti-Takeover Provisions
 ​
Articles of Incorporation and Bylaws and Louisiana Law.  Certain provisions of our articles of incorporation and bylaws and Louisiana law which deal with matters of corporate governance and rights of shareholders might be deemed to have a potential anti-takeover effect. Provisions in our articles of incorporation and bylaws provide, among other things,

 ​
		●	that our board of directors is divided into classes with only one-third of our directors standing for reelection each year;

​
		●	that no person shall directly or indirectly acquire or offer to acquire beneficial ownership of more than 10% of the issued and outstanding shares of any class of voting securities of Catalyst;

​
		●	that special meetings of shareholders may be called by shareholders who beneficially own at least 50% of the outstanding voting shares of Catalyst;

​
		●	that shareholders generally must provide us advance notice of shareholder proposals and director nominations and provide certain specified related information; and

​
		●	the authority to issue shares of authorized but unissued common stock and preferred stock and to establish the terms of any one or more series of preferred stock, including voting rights, without additional shareholder approval.

 ​
The provisions noted above as well as others provided under Louisiana law and federal banking law and regulation may have the effect of discouraging a future takeover attempt which is not approved by our board of directors but which individual shareholders may consider to be in their best interests or in which shareholders may receive a substantial premium for their shares over the then current market price. As a result, shareholders who might wish to participate in such a transaction may not have an opportunity to do so. The provisions may also render the removal of our board of directors or management more difficult. Furthermore, such provisions could render us being deemed less attractive to a potential acquiror and/or could result in our shareholders receiving a lesser amount of consideration for their shares of our common stock than otherwise could have been available either in the market generally and/or in a takeover.
​
A more detailed discussion of these and other provisions of our articles of incorporation and bylaws is set forth below.
​
Board of Directors.  Our articles of incorporation and bylaws provide that our board of directors is divided into three classes of directors each and that the members of each class be elected for a term of three years and until their successors are elected and qualified, with one class being elected annually. Holders of our common stock do not have cumulative voting in the election of directors.
 ​
Under our articles of incorporation, subject to the rights of the holders of any class or series of stock having preference over our common stock, any vacancy occurring in our board of directors, including any vacancy created by reason of an increase in the number of directors, may be filled by a majority vote of the remaining directors, whether or not a quorum is present. Any director so chosen to fill a vacancy will hold office until the term of the class to which he was appointed shall expire and until his or her successor is elected and qualified.
 ​
Our articles of incorporation also provide that, subject to the rights of the holder of any class or series of stock having preference over our common stock, any director may be removed by shareholders without cause by the affirmative vote of at least 75% of all outstanding shares entitled to vote in the election of directors, and may be removed with cause only upon the vote of at least a majority of the total votes eligible to be cast by shareholders. Cause for removal will be deemed to exist only if the director in question:
​
		●	declared of unsound mind by a court of competent jurisdiction;

​
		●	convicted of a felony or an offense punishable by imprisonment for a term of more than one year by a court of competent jurisdiction; or

​
		●	deemed liable by a court of competent jurisdiction for gross negligence or misconduct in the performance of duties to Catalyst.

Limitation on Voting Rights.  Article 10.A of our articles of incorporation provides that no person shall directly or indirectly offer to acquire or acquire the beneficial ownership of (i) more than 10% of the issued and outstanding shares of any class of an equity security of Catalyst, or (ii) any securities convertible into, or exercisable for, any equity securities of Catalyst if, assuming conversion or exercise by such person of all securities of which such person is the beneficial owner which are convertible into, or exercisable for, such equity securities (but of no securities convertible into, or exercisable for, such equity securities of which such person is not the beneficial owner), such person would be the beneficial owner of more than 10% of any class of an equity security of Catalyst. The term “person” is broadly defined to prevent circumvention of this restriction.
 ​
The foregoing restrictions do not apply to (i) any offer with a view toward public resale made exclusively to Catalyst by underwriters or a selling group acting on its behalf, (ii) any tax-qualified employee benefit plan or arrangement established by us and any trustee of such a plan or arrangement, and (iii) any other offer or acquisition approved in advance by the affirmative vote of two-thirds of our entire board of directors. In the event that shares are acquired in violation of Article 10.A, all shares beneficially owned by any person in excess of 10% shall be considered “Excess Shares” and shall not be counted as shares entitled to vote and shall not be voted by any person or counted as voting shares in connection with any matters submitted to shareholders for a vote, and the board of directors may cause such Excess Shares to be transferred to an independent trustee for sale on the open market or otherwise, with the expenses of such trustee to be paid out of the proceeds of sale.
​
Authorized Shares.  Article 4 of our articles of incorporation authorizes the issuance of 35,000,000 shares of stock, of which 5,000,000 shares shall be shares of serial preferred stock, and 30,000,000 shall be common stock. The shares of common stock and preferred stock were authorized in an amount greater than the amount issued and outstanding in order to provide our board of directors with as much flexibility as possible to effect, among other transactions, financings, acquisitions, stock dividends, stock splits and employee stock options. However, these additional authorized shares may also be used by the board of directors consistent with its fiduciary duty to deter future attempts to gain control of Catalyst. The board of directors also has sole authority to determine the terms of any one or more series of preferred stock, including voting rights, conversion rates, and liquidation preferences. As a result of the ability to fix voting rights for a series of preferred stock, the board has the power, to the extent consistent with its fiduciary duty, to issue a series of preferred stock to persons friendly to management in order to attempt to block a post-tender offer merger or other transaction by which a third party seeks control, and thereby assist management to retain its position.
 ​
Special Meetings of Shareholders and Shareholder Nominations and Proposals.  Article 9.B of the articles of incorporation provides that special meetings of shareholders may only be called by (i) the President, (ii) a majority of the board of directors, and (iii) by persons who beneficially own an aggregate of at least 50% of the outstanding voting shares, except as may otherwise be provided by law. The articles of incorporation also provide that any action permitted to be taken at a meeting of shareholders may be taken without a meeting if a consent in writing, setting forth the action so taken, is given by the holders of all outstanding shares entitled to vote and filed with the secretary of Catalyst.
 ​
Article 9.D of our articles of incorporation provides that only such business as shall have been properly brought before an annual meeting of shareholders shall be conducted at the annual meeting.
 ​
To be properly brought before an annual meeting, business must be specified in the notice of the meeting, or any supplement thereto, given by or at the direction of the board of directors, or otherwise properly brought before the meeting by a shareholder. For business to be properly brought before an annual meeting by a shareholder, the shareholder must have given timely notice thereof in writing to Catalyst’s secretary. To be timely, a shareholder’s notice must be delivered to or mailed and received at Catalyst’s principal executive offices not later than 120 days prior to the anniversary date of the mailing of proxy materials by Catalyst in connection with the immediately preceding annual meeting of shareholders, or, in the case of the Company’s first annual meeting of shareholders, by December 15, 2021. Catalyst’s articles of incorporation also require that the notice must contain certain information in order to be considered. The board of directors may reject any shareholder proposal not made in accordance with the articles of incorporation. The presiding officer of an annual meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with our articles of incorporation, and if he should so determine, he shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

 ​
Article 6.F. of our articles of incorporation provide that, subject to the rights of the holders of any class or series of stock having a preference over the common stock as to dividends or upon liquidation, all nominations for election to the board of directors, other than those made by the board or a committee thereof, shall be made by a shareholder who has complied with the notice provisions in such Article 6.F. Written notice of a shareholder nomination must include certain specified information and must be communicated to the attention of the secretary and either delivered to, or mailed and received at, Catalyst’s principal executive offices not later than (a) with respect to an annual meeting of shareholders, 120 days prior to the anniversary date of the mailing of proxy materials by Catalyst in connection with the immediately preceding annual meeting of shareholders; or, in the case of the Company’s first annual meeting of shareholders, by December 15, 2021.
​
Amendment of Articles of Incorporation and Bylaws.  Article 12 of our articles of incorporation generally provides that any amendment of the articles of incorporation must be first approved by a majority of the board of directors and then by the holders of a majority of the shares of Catalyst entitled to vote in an election of directors, except that the approval of 75% of the shares entitled to vote in an election of directors is required for any amendment to Articles 6 (directors), 7 (preemptive rights), 8 (indemnification), 9 (meetings of shareholders and shareholder proposals), 10 (restrictions on offers and acquisitions) and 12 (amendments).
 ​
Our bylaws may be amended by a majority of the board of directors or by the affirmative vote of a majority of the total shares entitled to vote in an election of directors, except that the affirmative vote of at least 75% of the total shares entitled to vote in an election of directors shall be required to amend, adopt, alter, change or repeal any provision inconsistent with certain specified provisions of the bylaws.

Trustee, which notice will identify each owner of a beneficial interest to be exchanged, the aggregate principal amount of each such beneficial interest and the CUSIP of the relevant Global Security; 

(B) the Company, in accordance with Section 2.04 of the Base Indenture, will promptly execute, and, upon receipt of a Company Request,
the Trustee, in accordance with Section 2.04 of the Base Indenture, will promptly authenticate and deliver to each such beneficial owner, Physical Securities registered in such beneficial owner’s name having an aggregate principal amount
equal to the aggregate principal amount of its exchanged beneficial interest and bearing any legends that such Physical Securities are required to bear under the Indenture and any applicable law; and 

(C) the Security Registrar, in accordance with the Applicable Procedures, will cause the principal amount of each relevant Global Security to
be decreased by the aggregate principal amount of the beneficial interests so exchanged. If all of the beneficial interests in a Global Security are so exchanged, such Global Security will be deemed surrendered to the Trustee for cancellation,
and the Trustee will cause such Global Security to be cancelled in accordance with the Applicable Procedures. 
 In each of the cases
described in clauses (1), (2) and (3) above, the Company may rely on the Depositary to provide all names of beneficial owners and their respective principal amounts beneficially owned and may issue Physical Securities registered in the names
and amounts so provided by the Depositary. 
 (e) Physical Securities. Except to the extent otherwise provided in
Section 2.03(a) hereof, Physical Securities may be transferred or exchanged in accordance with Section 2.05 of the Base Indenture. 

Section 2.04 Payments on the Securities. 

  
 11 

 (a) In General. Each Security will accrue interest at a rate equal to 5.50% per
annum from the most recent date to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, the Issue Date. Interest on a Security will cease to accrue upon the earliest of the Maturity Date, subject
to the provisions of Article 3 hereof, any Fundamental Change Purchase Date or Redemption Date for such Security, and subject to the provisions of Article 4 hereof, any Conversion Date for such Security. Interest on any Security will be payable
semi-annually in arrears on each Interest Payment Date, beginning September 15, 2022, to the Holder of such Security as of the Close of Business on the Regular Record Date immediately preceding the applicable Interest Payment Date. As
provided in Section 2.03 of the Base Indenture, interest will be computed on the basis of a 360-day year comprised of twelve 30-day months and, for a partial month,
on the basis of the number of days actually elapsed in a 30-day month. Pursuant to Section 6.04 hereof, in certain circumstances, the Company may be obligated to pay Holders Supplementary Interest. 

The Securities will mature on the Maturity Date, and on the Maturity Date, each Holder of a then Outstanding Security will be entitled on such
date to receive $1,000 in cash for each $1,000 in principal amount of then Outstanding Securities held, together with accrued and unpaid interest to, but not including, the Maturity Date on such then Outstanding Securities (except that accrued and
unpaid interest will be paid on the Maturity Date to Holders of record on the related Regular Record Date). 
 Notwithstanding anything to
the contrary, if the Maturity Date or any Interest Payment Date, Fundamental Change Purchase Date or Redemption Date or any Conversion Date falls, or if any payment, delivery, notice or other action by the Company is otherwise due, on a day that 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 immediately following Business Day with the same force and effect as if taken on such date, and no additional interest will accrue
and no Default shall occur on account of such delay. 
 (b) Method of Payment. The Company will pay the principal of, the
Fundamental Change Purchase Price for, and any cash portion of the Settlement Amount with respect to, any Physical Security to the Holder of such Security in cash at the designated office of the Paying Agent in the borough of Manhattan in The City
of New York, New York, prior to 11:00 a.m. on the relevant payment or settlement date, as the case may be. The Company will pay any interest on any Physical Security to the Holder of such Security (i) if such Holder holds $5,000,000 or
less aggregate principal amount of Securities, by check mailed to such Holder’s registered address, and (ii) if such Holder holds more than $5,000,000 aggregate principal amount of Securities, (A) by check mailed to such Holder’s
registered address or, (B) if such Holder delivers to the Security Registrar a written request that the Company make such payments by wire transfer to an account of such Holder within the United States, for each interest payment corresponding
to each Regular Record Date occurring during the period beginning on the date on which such Holder delivered such request and ending on the date, if any, on which such Holder delivers to the Security Registrar a written instruction to the contrary,
by wire transfer of immediately available funds to the account specified by such Holder. 
 The Company will pay the principal of, interest
on, the Fundamental Change Purchase Price or Redemption Price for, and any cash portion of the Settlement Amount with respect to, any Global Security to the Depositary by wire transfer of immediately available funds on the relevant payment date in
accordance with Applicable Procedures. 
 (c) Defaulted Payments. The Company shall pay any interest on the Securities that is
payable, but is not punctually paid or duly provided for, on the applicable Interest Payment Date, in accordance with Section 2.03 of the Base Indenture. Interest on any such interest amounts not paid or provided for shall accrue interest at
the rate of interest for the Securities. 
 ARTICLE 3 

REDEMPTIONS AND PURCHASES 

Section 3.01 Right of the Company to Redeem the Securities.  

(a) The Securities shall not be redeemable by the Company prior to the Maturity Date, except as described in this Article 3, and no sinking
fund is provided for the Securities. 
 (b) Subject to the terms of Section 3.01 through Section 3.06, on or after March 20,

 12 

 Section 3.02 Notice of Redemption.  

(a) To call any Securities for Redemption pursuant to Section 3.01, the Company shall fix a date for Redemption (a “Redemption
Date”) and the Company shall send or cause to be sent a notice of such Redemption (a “Notice of Redemption”) not less than 30 nor more than 45 Scheduled Trading Days prior to the Redemption Date to each Holder of Securities
so to be redeemed at its last address as the same appears on the Note Register; provided, however, that if the Company shall give a Notice of Redemption, it shall also give a written notice of the Redemption and Redemption Date to the Trustee and
the Paying Agent (if other than the Trustee). The Company shall issue a press release through such national newswire service as the Company then uses containing the information set forth in the Notice of Redemption. A Redemption Date must be a
Business Day of the Company’s choosing that is no more than 45, nor less than 30, Scheduled Trading Days after the Redemption Notice Date. 

(b) A Notice of Redemption, if delivered in the manner provided herein, shall be conclusively presumed to have been given duly, whether or not
the Holder receives such notice. In any case, failure to deliver such Notice of Redemption or any defect in the Notice of Redemption to the Holder of any Security designated for Redemption shall not affect the validity of the proceedings for the
redemption of any other Security. 
 (c) Each Notice of Redemption shall specify: 

(i) that the Securities have been called for Redemption, briefly describing the Company’s Redemption rights under the
Indenture; 
 (ii) the Redemption Date for such Redemption; 

(iii) the Redemption Price per $1,000 principal amount of Securities for such Redemption (and the amount, manner and timing of
any interest payment payable pursuant to Section 3.01); 
 (iv) the place or places where such Securities are to be
surrendered for payment of the Redemption Price; 
 (v) in case any Security 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 Security, a new Security in principal amount equal to the unredeemed portion thereof shall be issued; 

(vi) that Securities called for Redemption must be delivered to the Paying Agent (in the case of Physical Securities) or the
Applicable Procedures must be complied with (in the case of beneficial interests in Global Securities) for the Holder thereof to be entitled to receive the Redemption Price; 

(vii) that on the Redemption Date, the Redemption Price shall become due and payable upon each Security to be redeemed, and
that, unless the Company defaults in the payment of the Redemption Price, the interest thereon, if any, shall cease to accrue on and after the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date that is
prior to the Redemption Date to receive interest payable pursuant to Section 3.01); 
 (viii) that Holders may
surrender their Securities called for Redemption for conversion at any time on or after the Redemption Notice Date to the Close of Business on the second Scheduled Trading Day immediately preceding the Redemption Date or, if the Company fails to pay
the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price; 
 (ix) the
procedures a converting Holder must follow to convert its Securities called for Redemption and, if the Company chooses to elect a Settlement Method for any such exchanges, the relevant Settlement Method; 

  
 13 

 (x) the Conversion Rate and, if applicable, the number of shares of Common
Stock added to the Conversion Rate in accordance with Section 4.06; and 
 (xi) the CUSIP, ISIN or other similar
numbers, if any, assigned to such Securities. 
 A Notice of Redemption shall be irrevocable. In the case of a Redemption, a Holder may
convert any or all of its Securities called for Redemption at any time on or after the Redemption Notice Date to the Close of Business on the second Scheduled Trading Day immediately preceding the Redemption Date or, if the Company fails to pay the
Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price. 
 Section 3.03 Payment of
Securities Called for Redemption.  
 (a) If any Notice of Redemption has been given in respect of the Securities in accordance
with Section 3.02, the Securities shall become due and payable on the applicable Redemption Date at the place or places stated in the Notice of Redemption and at the applicable Redemption Price. On presentation and surrender of the Securities
at the place or places stated in the Notice of Redemption, the Securities shall be paid and redeemed by the Company at the applicable Redemption Price. 

(b) Prior to 11:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee (or other Paying Agent
appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) an amount of cash sufficient to pay the Redemption Price of all of the Securities to be redeemed
on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Securities to be redeemed shall be made on the Redemption Date for such Securities. The Trustee (or other Paying Agent appointed by the Company) shall,
promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price. 

Section 3.04 Selection, Conversion and Transfer of Securities to be Redeemed in Part.  

(a) If less than all Securities then outstanding are called for Redemption, then: 

(i) the Securities to be redeemed shall be selected by the Trustee as follows: (1) in the case of Global Securities, in
accordance with the Applicable Procedures; and (2) in the case of Physical Securities, by lot or pro rata; and 
 (ii)
if only a portion of a Security is subject to Redemption and such Security is converted in part, then the converted portion of such Security will be deemed to be from the portion of such Security that was subject to the Redemption. 

In the event of any Redemption, the Company shall not be required to (x) issue, register the transfer of or exchange any Securities
during the 15 calendar day period prior to the relevant Redemption Notice Date or (y) register the transfer of or exchange any Securities so selected for Redemption, in whole or in part, except the unredeemed portion of any Securities being
redeemed in part. 
 Section 3.05 Restrictions on Redemption. The Company may not redeem any Securities on any date if the
principal amount of the Securities 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 (or, if the Company fails to pay the Redemption Price, such later
date on which the Company pays the Redemption Price) (except in the case of an acceleration resulting from a Default by the Company in the payment of the Redemption Price with respect to such Securities). 

Section 3.06 Increased Conversion Rate Applicable to Securities Called for Redemption Surrendered for Conversion in Connection with a
Notice of Redemption. If a Holder of Securities called for Redemption elects to convert its Securities in connection with a Notice of Redemption pursuant to Section 4.01(b)(5) and Section 3.01, the Conversion Rate shall be increased by
a number of Additional Shares as provided in Section 4.06. 
 Section 3.07 Purchase at Option of Holders upon a Fundamental
Change. (a) If a Fundamental Change occurs, then each Holder shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Securities, or any portion thereof such that the
principal amount that remains outstanding of each Security that is not purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof, on a date (the “Fundamental Change Purchase Date”) specified by the

  
 14 

 
Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice, at a purchase price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon, if any, to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if the Company purchases a
Security on a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the Interest Payment Date corresponding to such Regular Record Date, the Company shall instead pay the full amount of accrued and unpaid interest
on such Security on the Interest Payment Date to the Holder of record of such Security as of such Regular Record Date and the Fundamental Change Purchase Price shall be equal to 100% of the principal amount of the Securities to be purchased. 

Purchases of Securities under this Section 3.07 shall be made, at the option of the Holder thereof, upon: 

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

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

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

(1) if certificated, the certificate numbers of such Securities; 

(2) the portion of the principal amount of such Securities, which must be such that the principal amount that is not to be purchased of each
Security that is not to be purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof; and 
 (3) that such
Securities are to be purchased by the Company pursuant to the applicable provisions of the Securities and the Indenture. 
 Notwithstanding
anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.07 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice
at any time prior to the Fundamental Change Expiration Time by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.09. 

If a Holder has already delivered a Fundamental Change Purchase Notice with respect to a Security, such Holder may not surrender such Security
for conversion until such Holder has validly withdrawn such Fundamental Change Purchase Notice (or, in the case of a Global Security, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with the terms of
Section 3.09. If a Holder has already delivered a Fundamental Change Purchase Notice, such Holder’s right to withdraw such notice and convert the Securities that are subject to repurchase will terminate at the Close of Business on the
Business Day immediately preceding the relevant Fundamental Change Purchase Date. 
 The Paying Agent shall promptly notify the Company of
the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. 
 (b) On or before the 20th calendar
day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Securities, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a notice (the “Fundamental Change
Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global Securities,
in accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall issue a press release or publish the information on the Company’s website or
through such other public medium as the Company may use at that time. 

  
 15 

 Each Fundamental Change Company Notice shall specify: 

(1) the events causing the Fundamental Change; 

(2) the date of the Fundamental Change; 

(3) the last date on which a Holder of Securities may exercise the purchase right pursuant to this Article 3; 

(4) the Fundamental Change Purchase Price; 

(5) the Fundamental Change Purchase Date; 

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

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

(8) that the Securities with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the
Holder withdraws the Fundamental Change Purchase Notice in accordance with the terms of the Indenture, if applicable; and 
 (9) the
procedures that Holders must follow to require the Company to purchase their Securities. 
 No failure of the Company to give the foregoing
notices and no defect therein shall limit the purchase rights of the Holders of Securities or affect the validity of the proceedings for the purchase of the Securities pursuant to this Section 3.07. 

(c) Notwithstanding the foregoing, there shall be no purchase of any Securities pursuant to this Section 3.07 if the principal amount of
the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental
Change Purchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Physical Securities held by it during the acceleration of the Securities (except in the case of an acceleration
resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Securities) and shall deem to be cancelled any instructions for book-entry transfer of the Securities in compliance with the
procedures of the Depositary, in which case, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn. 

(d) Notwithstanding anything to the contrary in this Section 3.07, the Company shall not be required to repurchase, or to make an offer
to repurchase, Securities upon a Fundamental Change if: 
 (1) a third party makes the offer in the manner, at the times, and
otherwise in compliance with the requirements set forth in the Indenture applicable to an offer by the Company to repurchase Securities upon a Fundamental Change and such third party purchases all Securities validly tendered and not withdrawn upon
such offer in the manner and otherwise in compliance with such requirements; or 
 (2) pursuant to clause (2) of the
definition thereof (or a Fundamental Change pursuant to clause (1) which also results in a Fundamental Change pursuant to clause (2)), if (i) such Fundamental Change results in the Securities becoming convertible (pursuant to the
provisions described in Section 4.07(a)) into an amount of cash per Security that is greater than (x) the Fundamental Change Purchase Price (assuming the maximum amount of accrued interest would be payable based on the latest possible
Fundamental Change Purchase Date), plus (y) to the extent that the 35th Trading Day immediately following the Effective Date of such Fundamental Change is after a Regular Record Date and on or prior to the Business Day immediately
following the corresponding Interest Payment Date, the full amount of interest payable per Security on such Interest Payment Date and (ii) the Company provides timely notice of the Holders’ right to convert their Securities based on such
Fundamental Change as described in Section 4.01(b)(4) (the requirements set forth in clauses (i) and (ii) of this Section 3.07(d)(2), the “Adequate Cash Conversion Provisions”). 

  
 16 

 Section 3.08 Effect of Fundamental Change Purchase Notice. Upon receipt by
the Paying Agent of a Fundamental Change Purchase Notice specified in Section 3.07, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is
withdrawn in accordance with Section 3.09) thereafter be entitled to receive solely the Fundamental Change Purchase Price in cash with respect to such Security (and any previously accrued and unpaid interest on such Security). Such
Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the applicable Fundamental Change Purchase Date (provided the conditions in Section 3.07 have been
satisfied) and (y) the time of delivery or book-entry transfer of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.07, subject in each case to extensions to comply with applicable law. 

Section 3.09 Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in
whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the Fundamental Change Expiration Time, specifying: 

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

(2) if Physical Securities have been issued, the certificate numbers of the withdrawn Securities; and 

(3) the principal amount, if any, of each Security that remains subject to the Fundamental Change Purchase Notice, which must be such that the
principal amount not to be purchased equals $1,000 or an integral multiple of $1,000 in excess thereof; 
 provided, however, that if the
Securities are Global Securities, the notice must comply with Applicable Procedures of the Depositary. 
 The Paying Agent will promptly
return to the respective Holders thereof any Physical Securities with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.09. 

Section 3.10 Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m., New York City time, on the Fundamental Change
Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in
immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying
Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Securities for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with the Indenture on the Fundamental Change Purchase Date,
then as of such Fundamental Change Purchase Date, (a) such Securities will cease to be Outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Securities is made or such Securities have been delivered
to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest upon delivery or book-entry
transfer of such Securities). 
 Section 3.11 Securities Purchased in Whole or in Part. Any Security that is to be
purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Securities, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is
not purchased. Any Holder whose Securities are purchased pursuant to this Article 3 shall receive payment of the Fundamental Change Purchase Price on the later of (i) the Fundamental Change Purchase Date or (ii) the time of book-entry
transfer or the delivery of the Securities so purchased. 
 Section 3.12 Covenant To Comply with Applicable Laws upon Purchase of
Securities. In connection with any offer to purchase Securities under Section 3.07, the Company shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with any
other U.S. federal or state securities laws applicable to the Company in connection with such purchase offer, in each case, so as to permit the rights and obligations under Section 3.07 to be exercised in the time and in the manner specified in
Section 3.07. 
 Section 3.13 Repayment to the Company. To the extent that the aggregate amount of cash deposited by
the Company pursuant to Section 3.10 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the
Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company.

 ARTICLE 4 

CONVERSION 

Section 4.01 Right To Convert. (a) Subject to and upon compliance with the provisions of the Indenture, each Holder shall
have the right, at such Holder’s option, to convert its Securities, or any portion of its Securities such that the principal amount that remains Outstanding of each Security that is not converted in full equals $1,000 or an integral multiple of
$1,000 in excess thereof, into the Settlement Amount determined in accordance with Section 4.03(a) hereof, (x) prior to the Close of Business on the Business Day immediately preceding December 15, 2026, only upon satisfaction of one
or more of the conditions described in Section 4.01(b) hereof, and (y) on or after December 15, 2026, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date. 

(b) (1) A Holder may surrender Securities for conversion during any calendar quarter commencing after June 30, 2022 (and only during such
calendar quarter) 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 the last Trading Day of the immediately preceding calendar
quarter is greater than or equal to 110% of the Conversion Price in effect on each applicable Trading Day. 
 (2) A Holder may surrender all
or a portion of its Securities for conversion during the five Business Day period after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Securities, as
determined following a request by a Holder in accordance with the procedures set forth in this Section 4.01(b)(2), for each Trading Day of such Measurement Period was less than 98% of the product of (i) the Last Reported Sale Price of the
Common Stock on such Trading Day and (ii) the Conversion Rate in effect on such Trading Day. The Trading Price shall be determined by the Bid Solicitation Agent pursuant to this Section 4.01(b)(2) and the definition of “Trading
Price” set forth in Section 1.02 hereof. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company in
accordance with the definition of Trading Price, along with the appropriate contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price of the Securities unless
the Company has requested such determination; and the Company shall have no obligation to make such request (or, if the Company is the Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price of the Securities)
unless a Holder of at least $5.0 million in aggregate principal amount of notes requests in writing that it make such a determination and provides it with reasonable evidence that the Trading Price per $1,000 principal amount of Securities
would be less than 98% of the product of (i) the Last Reported Sale Price of the Common Stock on such Trading Day and (ii) the Conversion Rate in effect on such Trading Day. At such time, the Company shall instruct the Bid
Solicitation Agent (if other than the Company) to determine (or, if the Company is the Bid Solicitation Agent, the Company shall determine) the Trading Price per $1,000 principal amount of the Securities beginning on the next Trading Day and on each
successive Trading Day until the Trading Price per $1,000 principal amount of Securities for a Trading Day is greater than or equal to 98% of the product of (i) the Last Reported Sale Price of the Common Stock on such Trading Day and
(ii) the Conversion Rate in effect on such Trading Day. Whenever the condition to conversion set forth in this Section 4.01(b)(2) has been met, but was not met on the immediately preceding Trading Day, the Company will so notify the
Holders and the Trustee. If, at any time after the condition to conversion set forth in this Section 4.01(b)(2) has been met, the condition to conversion set forth in this Section 4.01(b)(2) ceases to be met, the Company will so
notify the Holders and the Trustee on the first Trading Day on which such condition ceases to be met. 
 (3) If, prior to the Close of
Business on the Business Day immediately preceding December 15, 2026, the Company elects to (x) issue to all or substantially all holders of the Common Stock rights, options or warrants entitling them for a period of not more than 45
calendar days after the date of such issuance to subscribe for or purchase shares of the Common Stock, at a price per share 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 (taking into account any consideration received by the Company as described in Section 4.04(b)); or (y) distribute to all or substantially
all holders of the Common Stock the Company’s assets, debt securities or rights to purchase the Company’s securities, which distribution (excluding for this purpose a distribution required to avoid the imposition of tax on undistributed
income) has a per-share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of
announcement for such distribution, then, the Company must deliver notice of such issuance or 

  
 18 

 
distribution, and of the Ex-Dividend Date for such issuance or distribution, to the Holders at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Holders may surrender their Securities for conversion at any time during the period beginning on the 30th Scheduled Trading Day immediately prior to the Ex-Dividend Date for such issuance or distribution and ending on the earlier of (a) the Close of Business on the Business Day immediately preceding the Ex-Dividend Date
for such issuance or distribution or (b) the Company’s announcement that such issuance or distribution will not take place, even if the Securities are not otherwise convertible at such time; provided, however, that Holders
may not convert their Securities pursuant to this Section 4.01(b)(3) if the Company provides that Holders shall participate, at the same time and upon the same terms as holders of the Common Stock, and as a result of holding the Securities, in
the relevant issuance or distribution without having to convert their Securities as if they held a number of shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such
issuance or distribution multiplied by the principal amount (expressed in thousands) of Securities held by such Holder on the Ex-Dividend Date for such issuance or distribution. 

(4) If, prior to the Close of Business on the Business Day immediately preceding December 15, 2026, (i) a Make-Whole Fundamental Change
occurs or (ii) the Company is a party to (a) a consolidation, merger or binding share exchange, pursuant to which the Common Stock would be converted into cash, securities or other assets or (b) a sale, conveyance, transfer or lease
of all or substantially all of the assets of the Company and its Subsidiaries, on a consolidated basis, to another Person (other than any of the Company’s Subsidiaries), the Securities may be surrendered for conversion at any time from or after
the Open of Business on the Business Day immediately following the day the Company publicly announces such transaction (even if such transaction has not yet occurred) until the earlier of (i) the Close of Business on the 35th trading day
immediately following the actual effective date of such transaction or, if such transaction or event is a Fundamental Change (other than a Fundamental Change for which the Company validly invokes the Adequate Cash Conversion Provisions), until the
Close of Business on the Business Day immediately preceding the related Fundamental Change Purchase Date and (ii) the second Scheduled Trading Day immediately preceding the Maturity Date. The Company will notify the Holders of any such
transaction as promptly as practicable following the date the Company publicly announces such transaction and the Company will use commercially reasonable efforts to notify Holders in writing prior to such effective date, if practicable.

If a Holder has already delivered a Fundamental Change Repurchase Notice with respect to a Security, such Holder may not surrender such
Security for conversion until such Holder has validly withdrawn such Fundamental Change Repurchase Notice (or, in the case of a Global Security, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with the
terms of Section 3.09. If a Holder has already delivered a Fundamental Change Repurchase Notice, such Holder’s right to withdraw such notice and convert the Securities that are subject to repurchase will terminate at the Close of Business
on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date. 
 (5) (A) If the Company calls any Security for
Redemption pursuant to Section 3.01, the Holder may convert such Security (or a portion thereof) called for Redemption at any time from, and including, the Redemption Notice Date until the Close of Business on the second Scheduled Trading Day
immediately preceding the related Redemption Date, or, if the Company fails to pay the Redemption Price, such later date on which the Company pays or duly provides for the Redemption Price. If the Company has designated a Redemption Date pursuant to
Section 3.02, a Holder that complies with the requirements for conversion described herein shall be deemed to have delivered a notice of its election not to have its Securities so redeemed. 

(B) If the Company elects to redeem less than all of the outstanding Securities pursuant to Section 3.02, and the Holder of any Security
(or any owner of a beneficial interest in any Global Security) is reasonably not able to determine, before the Close of Business on the 26th Scheduled Trading Day immediately before the related Redemption Date, whether such Security or beneficial
interest, as applicable, is to be redeemed pursuant to such Redemption (and, as a result thereof, convertible in accordance with the provisions of the Indenture), then such Holder or owner, as applicable, shall be entitled to convert such Security
or beneficial interest, as applicable, at any time before the Close of Business on the second Scheduled Trading Day immediately preceding such Redemption Date, unless the Company defaults in the payment of the Redemption Price, in which case such
Holder or owner, as applicable, shall be entitled to convert such Security or beneficial interest, as applicable, until the Redemption Price has been paid or duly provided for, and each such conversion shall be deemed to be of a Security called for
Redemption for the purposes of this Section 4.01(b)(5), Section 4.06 and Section 3.02. 
 (c) Notwithstanding any other
provision of the Securities or the Indenture, no Holder of Securities will be entitled to receive Common Stock following conversion of such Securities to the extent that receipt of such Common Stock would cause such Holder to exceed the ownership
limitations contained in the Company’s charter. 

  
 19 

 (d) If any delivery of shares of Common Stock owed to a Holder upon conversion of Securities
is not made, in whole or in part, as a result of the limitations described in Section 4.01(c), the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such shares as promptly as practicable
after any such converting Holder gives notice to the Company that such delivery would not result in it exceeding the ownership limitations in the Company’s charter. 

Section 4.02 Conversion Procedures. 

(a) Each Security shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures
of the Depositary. 
 (b) To exercise the conversion privilege with respect to a beneficial interest in a Global Security (which conversion
request is irrevocable), the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or
the Conversion Agent, and pay the funds, if any, required by Section 4.02(f) and any taxes or duties if required pursuant to Section 4.02(g), and the Conversion Agent must be informed of the conversion in accordance with the customary
practice of the Depositary. 
 To exercise the conversion privilege with respect to any Physical Securities, the Holder of such Physical
Securities shall: 
 (1) complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the
“Conversion Notice”) or a facsimile of the Conversion Notice; 
 (2) deliver the Conversion Notice, which is irrevocable,
and the Security to the Conversion Agent; 
 (3) if required, furnish appropriate endorsements and transfer documents, 

(4) if required, make any payment required under Section 4.02(f); and 

(5) if required, pay all transfer or similar taxes as set forth in Section 4.02(g). 

If, upon conversion of a Security, any shares of Common Stock are to be issued to a Person other than the Holder of such Security, the related Conversion
Notice shall include such other Person’s name and address. 
 If a Security is subject to a Fundamental Change Purchase Notice, such
Security may not be converted unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.09 hereof prior to the relevant Fundamental Change Expiration Time, except to the extent that a portion of such Holder’s
Security is not subject to such Fundamental Change Purchase Notice. If a Holder has already delivered a Fundamental Change Repurchase Notice, such Holder’s right to withdraw such notice and convert the Securities that are subject to repurchase
will terminate at the Close of Business on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date. If the Company has designated a Redemption Date pursuant to Section 3.02, a Holder that complies with the
requirements for conversion set forth in this Section 4.02(b) shall be deemed to have delivered a notice of its election not have its Securities so redeemed. 

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

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) surrendered for conversion at the Close
of Business on the applicable Conversion Date; provided, however, that the Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of
the Close of Business on (i) such Conversion Date (in the case of Physical Settlement) or (ii) the last VWAP Trading Day of the applicable Observation Period (in the case of Combination Settlement) except to the extent required by
Section 4.04 hereof. At the Close of Business on the Conversion Date for a Security, the converting Holder shall no longer be the Holder of such Security. 

  
 20 

 (c) Endorsement. Any Securities surrendered for conversion shall, unless shares
of Common Stock issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or
its duly authorized attorney. 
 (d) Physical Securities. If any Securities in a denomination greater than $1,000 shall be
surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge, new Securities in authorized denominations in an aggregate principal amount
equal to the unconverted portion of the surrendered Securities. 
 (e) Global Securities. Upon the conversion of a beneficial
interest in Global Securities, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected
through any Conversion Agent other than the Trustee. 
 (f) Interest Due Upon Conversion. If a Holder converts a Security after
the Close of Business on a Regular Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Security with an amount of cash equal to the amount of interest
payable on such Security on the corresponding Interest Payment Date (regardless of whether the converting Holder was the Holder of record on the corresponding Regular Record Date); provided, however, that a Holder need not make such
payment (1) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has issued a Notice of Redemption with respect to such Security being converted for redemption on a Redemption
Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date
and on or prior to the corresponding Interest Payment Date; or (4) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security. 

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

 Section 4.03 Settlement Upon Conversion. 

(a) Settlement Amount. Subject to this Section 4.03 and Section 4.06(b), if a Holder converts a Security, the Company
shall pay or deliver to such Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, solely cash, solely shares of Common Stock (together with cash in lieu of fractional shares as provided herein) or a
combination of cash and Common Stock (the “Settlement Amount”), at the Company’s election, as set forth in this Section 4.03. 

(1) Except as described under Sections 4.06 and 4.07, the Company shall pay or deliver, as the case may be, the Settlement Amount on: 

(A) if the Company elects to fulfill its conversion obligation by Cash Settlement or Combination Settlement, the second
Business Day immediately following the last VWAP Trading Day of the Observation Period; and 
 (B) if the Company elects to
fulfill its conversion obligation by Physical Settlement, the second Business Day following the relevant Conversion Date for any conversion occurring prior to the Regular Record Date immediately preceding the Maturity Date, or on the Maturity Date
for any conversion occurring on or after the Regular Record Date immediately preceding the Maturity Date. 
 (2) All conversions
(i) during the Final Conversion Period, (ii) occurring after the date of issuance of a Notice of Redemption pursuant to Section 3.02 and prior to the Close of Business on the second Scheduled Trading Day immediately preceding the
related Redemption Date, and (iii) following the Company’s irrevocable election of a Settlement Method pursuant to Section 4.03(a)(4), will be settled using the same Settlement Method (including the same relative proportion of cash
and/or shares of the Common Stock). 
 (3) Except for (i) any conversions for which the relevant Conversion Date occurs during the Final
Conversion Period, (ii) any conversions occurring after the date of issuance of a Notice of Redemption pursuant to Section 3.02 and prior to the Close of Business on the second Scheduled Trading Day immediately preceding the related
Redemption Date, and (iii) any conversion following the Company’s irrevocable election of a Settlement Method, in each case, the Company will elect (or be deemed to have elected) the same Settlement Method for all conversions occurring on
any given Conversion Date; provided that the Company need not elect the same Settlement Method with respect to conversions that occur on different Conversion Dates. 

  
 21 

 (4) Subject to the Company’s irrevocable election of a Settlement Method as described
in this Section 4.03(a)(4), if the Company elects a Settlement Method, the Company shall deliver notice (each, a “Settlement Notice”) to Holders so converting through the Trustee of the relevant Settlement Method not later than
the Close of Business on the second Trading Day following the related Conversion Date, or in the case of any conversions for which the relevant Conversion Date occurs during the Final Conversion Period, no later than the 35th Scheduled Trading Day prior to the Maturity Date, or in the case of any conversion occurring after the date of issuance of a Notice of Redemption pursuant to Section 3.02 and prior to the Close
of Business on the second Scheduled Trading Day immediately preceding the related Redemption Date, in such Notice of Redemption. With respect to each Conversion Date occurring during the Final Conversion Period, the Company shall, prior to the
Final Conversion Period, deliver a single Settlement Notice that shall apply to all conversions occurring during the Final Conversion Period. Each such Settlement Notice shall specify whether the Company shall satisfy its conversion obligation
by (i) delivering solely shares of Common Stock (together with cash in lieu of fractional shares as provided herein) (“Physical Settlement”), (ii) paying solely cash (“Cash Settlement”) or (iii) paying and
delivering, as the case may be, a combination of cash and shares of Common Stock (“Combination Settlement”). In the case of an election that provides for Combination Settlement, the relevant Settlement Notice shall indicate the
Specified Dollar Amount. If the Company does not deliver a Settlement Notice within the time periods specified above, the Company will no longer have the right to elect Cash Settlement or Physical Settlement with respect to that Conversion Date
and will be deemed to have elected Combination Settlement with a Specified Dollar Amount of $1,000. If the Company provides a Settlement Notice within the time periods specified above and elects Combination Settlement but the Settlement Notice does
not specify a Specified Dollar Amount, the Company will be deemed to have elected Combination Settlement with a Specified Dollar Amount of $1,000 per $1,000 of principal amount of Securities. By notice to the Holders and the Trustee, the Company may
prior to the Close of Business on the Scheduled Trading Day immediately preceding the Final Conversion Period, at the Company’s option, irrevocably elect to satisfy its conversion obligation with respect to the Securities through Combination
Settlement with a Specified Dollar Amount of $1,000 for all Conversion Dates occurring subsequent to the delivery of such notice and for which another Settlement Method does not otherwise apply. If the Company irrevocably elects Combination
Settlement with an ability to continue to set the Specified Dollar Amount, the Company will, after the date of such election, notify the Trustee and the Conversion Agent (if other than the Trustee) and either post the fixed Settlement Method on its
website or disclose the same in a Current Report on Form 8-K (or any successor form) that is filed with the SEC. 

(5) The Settlement Amount in respect of any conversion shall be computed as follows: 

(A) if the Company elects Physical Settlement, the Company will deliver to the converting Holder a number of shares of Common
Stock equal to (1) (i) the aggregate principal amount of Securities to be converted, divided by (ii) $1,000, multiplied by (2) the then-applicable Conversion Rate on the date the converting Holder becomes a record owner of Common
Stock pursuant to the last paragraph of Section 4.02(b) (plus cash in lieu of any fractional shares); 
 (B) if the
Company elects Cash Settlement, the Company shall pay to the converting Holder cash in an amount per $1,000 principal amount of Securities being converted equal to the sum of the Daily Conversion Values for each of the 25 consecutive VWAP Trading
Days during the related Observation Period; and 
 (C) if the Company elects (or is deemed to have elected) Combination
Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder, as the case may be, in respect of each $1,000 principal amount of Securities being converted, a Settlement Amount equal to the sum of the Daily Settlement
Amounts for each of the 25 consecutive VWAP Trading Days during the related Observation Period (plus cash in lieu of any fractional shares). 

(6) The “Daily Settlement Amount” for each of the 25 consecutive VWAP Trading Days of the applicable Observation Period, will
consist of: 
 (A) cash equal to the lesser of (i) a dollar amount per Security to be received upon conversion as
specified by the Company in the Settlement Notice (or deemed specified as set forth above) (the “Specified Dollar Amount”), if any, divided by 25 (such quotient being referred to as the “Daily Measurement
Value”) and (ii) the Daily Conversion Value; and 

  
 22 

 (B) to the extent the Daily Conversion Value for such Trading Day exceeds
the Daily Measurement Value for such Trading Day, a number of shares of Common Stock equal to (i) the difference between the Daily Conversion Value and the Daily Measurement Value, divided by (ii) the Daily VWAP of the Common Stock
for such VWAP Trading Day. 
 (7) In the case of Cash Settlement or Combination Settlement, the Settlement Amount or Daily Conversion Values
shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination, the Company shall notify the Trustee and the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion
Values, as the case may be, and the amount of cash deliverable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent shall be entitled to rely exclusively on the notice given by the Company and shall have no
responsibility for any such determination. 
 (b) Fractional Shares. Notwithstanding the foregoing, the Company will not issue
fractional shares of Common Stock with respect to any converted Security in respect of which shares of Common Stock are deliverable. Instead, if any such shares of Common Stock includes a fraction of a share of Common Stock, the Company will, in
lieu of delivering such fraction of a share of Common Stock, pay an amount of cash equal to the product of (i) such fraction of a share and (ii) the Daily VWAP of the Common Stock on the relevant Conversion Date (in the case of Physical
Settlement) or on the last VWAP Trading Day of the applicable Observation Period (in the case of Combination Settlement), subject in each case to the following paragraph. 

If a Holder surrenders more than one Security for conversion on a single Conversion Date, the Company will calculate the amount of cash and
the number of shares of Common Stock due with respect to such Securities as if such Holder had surrendered for conversion one Security having an aggregate principal amount equal to the sum of the principal amounts of each of the Securities
surrendered for conversion by such Holder on such Conversion Date. 
 (c) Settlement of Accrued Interest and Deemed Payment of
Principal. Subject to Section 4.02(f), if a Holder converts a Security, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Security and the Company’s delivery of the amount of cash
and the number of shares of Common Stock, if any, into which a Security is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Security
to, but excluding, the Conversion Date; provided, however, that if a Holder converts a Security after the Close of Business on a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the
Company will still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Security on such Regular Record Date. As a result of the foregoing, and Section 4.02(f), the Company will pay accrued and unpaid
interest on the Maturity Date on all Securities converted after the Regular Record Date immediately preceding the Maturity Date to the holders of record of such Securities on such Regular Record Date, and converting Holders will not be required to
pay the Company equivalent amounts. 
 As a result, except as otherwise provided in the proviso to the first sentence of the immediately
preceding paragraph, any accrued and unpaid interest with respect to a converted Security will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, except as otherwise provided in the proviso to the first
sentence of the immediately preceding paragraph, if the Settlement Amount for any Security includes both cash and shares of the Common Stock, accrued and unpaid interest will be deemed to be paid first out of the amount of cash delivered upon such
conversion. Except as otherwise provided herein, in no event will a Holder be entitled to receive any dividend or other distribution with respect to any Common Stock issued on conversion of such Holder’s Securities if the applicable Conversion
Date is after the Regular Record Date for such dividend or distribution. Prior to any conversion in accordance with this Section 4.03, a Holder shall not be the owner of any Common Stock issuable upon conversion of such Holder’s
Securities. 
 (d) Notices. Whenever a Conversion Date occurs with respect to a Security, the Conversion Agent will, as promptly
as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, notice that a Conversion Date has occurred, which notice will state
such Conversion Date, the principal amount of Securities converted on such Conversion Date and the names of the Holders that converted Securities on such Conversion Date. 

Section 4.04 Adjustment of Conversion Rate. The Conversion Rate will be adjusted as described in this Section 4.04,
except that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and as a
result of holding the Securities, in any of the transactions described below without having to convert their Securities, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal
amount (expressed in thousands) of Securities held by such Holder. 

  
 23 

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

 

							
	 CR1
	  	 =
	  	 CR0 x
	  	OS1
		  		  		  	OS0

 where, 
  

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

 Any adjustment made under this Section 4.04(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. If any dividend or
distribution of the type described in this Section 4.04(a) is declared but not so paid or made, or any share split or share combination of the type described in this Section 4.04(a) is announced but the outstanding shares of the Common
Stock are not split or combined, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding shares of the
Common Stock, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or share combination had not been announced. 

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period
of not more than 45 calendar days after the date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share 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 will be increased based on the following formula: 

 

							
	 CR1
	  	 =
	  	 CR0 x
	  	    OS0 + X    
		  		  		  	OS0 + Y

 where, 
  

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

  
 24 

 
					
	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 4.04(b) will be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or warrants are not
exercised prior to their expiration or shares of Common Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase
with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if no such rights,
options or warrants are exercised prior to their expiration, the Conversion Rate shall be decreased to be 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 4.04(b) and Section 4.01(b)(3) hereof, in determining whether any rights, options or
warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than such average of the Last Reported Sale Prices 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 the Common Stock, there shall be taken into account any consideration
received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,
options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding: 

(1) dividends, distributions, rights options or warrants as to which an adjustment was effected pursuant to Section 4.04(a) hereof or
Section 4.04(b) hereof; 
 (2) rights issued under a shareholders rights plan (except as described in Section 4.04(g)); 

(3) dividends or distributions paid exclusively in cash; 

(4) dividends or distributions in connection with a Merger Event, as described under Section 4.07(a); and 

(5) Spin-Offs as to which the provisions set forth below in this Section 4.04(c) shall apply; 

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

							
	 CR1
	  	 =
	  	 CR0 x
	  	        SP0        
		  		  		  	SP0 - FMV

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
	SP0	  	=	  	the average of the Last Reported Sale Prices 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 shares of the Company’s Capital Stock, evidences the Company’s indebtedness, other assets, or property of the Company or rights, options or warrants to
acquire the Company’s Capital Stock or other securities distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

  
 25 

 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 Securities shall receive, in respect of each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of the Common
Stock, the amount and kind of the Company’s Capital Stock, evidences of the Company’s indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that
such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. 

Any increase made under the portion of this Section 4.04(c) will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.
 With respect to an adjustment pursuant to this Section 4.04(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 of the Company or other business unit of the Company, and such Capital Stock or
similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate
will be increased based on the following formula: 
  

							
	 CR1
	  	 =
	  	 CR0 x
	  	FMV0 + MP0
		  		  		  	MP0

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such Spin-Off;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of Last Reported
Sale Price per share as set forth in Section 1.02 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
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 The adjustment to the applicable Conversion Rate under the preceding paragraph of this
Section 4.04(c) will be made immediately after the Open of Business on the day after the last Trading Day of the Valuation Period, but will be given effect as of the Open of Business on the Ex-Dividend
Date for the Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of
the Observation Period in respect of any conversion, references within this Section 4.04(c) to 10 Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values in respect of that conversion, 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. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Ex-Dividend Date for any
Spin-Off, references within the portion of this Section 4.04(c) related to “Spin-Offs” to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from,
and including, the Ex-Dividend Date for such Spin-Off to, and including, the relevant Conversion Date.

 For purposes of the second adjustment set forth in this clause 4.04(c), (i) the Last
Reported Sale Price of any Capital Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock in the definition of “Last Reported Sale Price” set
forth in Section 1.02 hereof, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a
manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be
included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest. 

Subject to Section 4.04(g), for the purposes of this Section 4.04(c), rights, options or warrants distributed by the Company to all
holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or
events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have
been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this Section 4.04(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 4.04(c). If any such right, option or warrant, distributed prior to the Issue Date 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 of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without
exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto
that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been
redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall
then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock
with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights,
options or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 

For purposes of Section 4.04(a) hereof, Section 4.04(b) hereof and this Section 4.04(c), if any dividend or distribution to
which this Section 4.04(c) applies includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which
Section 4.04(a) hereof also applies (the “Clause A Distribution”); or 
 (B) a dividend or distribution of rights,
options or warrants to which Section 4.04(b) hereof also applies (the “Clause B Distribution”), 
 then (i) such dividend or
distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate
adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion
Rate adjustment required by Section 4.04(b) hereof with respect thereto shall then be made, except that, if determined by the Company, (A) the “Ex-Dividend Date” of the Clause B
Distribution and the Clause A Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the
Clause B Distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 4.04(b) hereof, and (iii) the
Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may be, except that, if determined by the Company, (A) the
“Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution, if any, shall be deemed to be the Ex-Dividend Date of the Clause C Distribution,
and (B) any shares of Common Stock included in the Clause A distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective
date” within the meaning of Section 4.04(a) hereof. 

  
 27 

 (d) If any cash dividend or distribution is made to all or substantially all holders of the
Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds the dividend threshold amount (the “DTA”) for such quarter, the Conversion Rate shall be adjusted based on the
following formula: 
  

							
	 CR1
	  	 =
	  	 CR0 x
	  	        SP0        
		  		  		  	SP0 – C

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
			
	DTA	  	=	  	the dividend threshold amount, which shall initially be $0.62 per quarter; and
	C	  	=	  	the amount in cash per share that the Company distributes to holders of the Common Stock in excess of the DTA

 The DTA is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is
adjusted other than adjustments made pursuant to this Section 4.04(d). If an adjustment is required to be made as set forth in this Section 4.04(d) as a result of a distribution that is not a regular, periodic dividend, the DTA will be
deemed to be zero with respect to that particular adjustment. Notwithstanding the foregoing, if at any time dividends are distributed other than on a quarterly basis, the DTA shall be appropriately adjusted and shall apply to such dividends. 

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 shall receive, for each $1,000 principal amount of Securities it holds, 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 had owned a number of shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. Any increase made pursuant to this Section 4.04(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, effective as of the date the Board
of Directors or a committee thereof determines not to make or pay such dividend or distribution, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer 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 Price 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 “Offer Expiration Date”), the Conversion Rate shall be increased based on the
following formula: 
  

							
	 CR1
	  	 =
	  	 CR0 x
	  	AC + (SP1 x OS1)
		  		  		  	OS0 x SP1

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the Close of Business on the Offer Expiration Date;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Close of Business on the Offer Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange
offer;

  
 28 

					
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or
exchange in such tender offer or exchange offer);
			
	OS1	  	    	  	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange
in such tender or exchange offer); and
			
	SP1	  	    	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Offer Expiration Date.

 The adjustment to the applicable Conversion Rate under the preceding paragraph of this
Section 4.04(e) will be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. If the Trading Day next succeeding the Offer Expiration Date is less than 10 Trading Days prior to, and including, the
end of the Observation Period in respect of any conversion, references within this Section 4.04(e) to 10 Trading Days shall be deemed replaced, solely in respect of such conversion, for purposes of calculating the affected Daily Conversion
Values in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the last Trading Day of such Observation Period. For
purposes of determining the applicable Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this Section 4.04(e) to 10 Trading Days
shall be deemed replaced, solely in respect of such conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the relevant Conversion Date.

 (f) Special Settlement Provisions. Notwithstanding anything to the contrary herein, with respect to any Securities as to which
Physical Settlement is applicable, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Securities on or prior to the related
Regular Record Date would be treated as the record holder of shares of Common Stock in accordance with the provisions of the last paragraph of Section 4.02(b) as of a date on or after such Ex-Dividend
Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such
Holder will 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) Poison Pill. Whenever a Holder converts a Security, to the extent that the Company has a shareholders rights plan in effect,
the Holder converting such Security will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion, the rights under the shareholders rights plan unless the rights have separated from the Common Stock,
in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights,
options or warrants as described in Section 4.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such rights. 

(h) Deferral of Adjustments. Notwithstanding anything to the contrary herein, the Company will not be required to adjust the
Conversion Rate unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in
any subsequent adjustment, and provided, further, that any such adjustment of less than one percent that has not been made shall be made upon the occurrence of (i) the Effective Date for any Make-Whole Fundamental Change,
(ii) on each VWAP Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement), (iii) on the Conversion Date for any Securities (in the case of Physical Settlement) and (iv) on the date of a Notice of
Redemption. In addition, the Company shall not account for such deferrals when determining whether any of the conditions to conversion have been satisfied or what number of shares of Common Stock a Holder would have held on a given day had it
converted its Securities. 
 (i) Limitation on Adjustments. Except as stated in this Section 4.04, the Company will not
adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable
securities. If, however, the application of the formulas in Sections 4.04(a) through (e) hereof would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the
Conversion Rate will be made (other than as a result of a reverse share split, share combination or readjustment). 

  
 29 

 In addition, notwithstanding anything to the contrary herein, the Conversion Rate will not
be adjusted: 
 (1) on account of stock repurchases that are not tender offers referred to in Section 4.04(e) hereof, including
structured or derivative transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors or otherwise; 

(2) 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 Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 

(3) 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, program or agreement of or assumed by the Company or any of its Subsidiaries; 
 (4) upon the issuance
of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding clause (3) and outstanding as of the date the Securities were first issued; 

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

(6) for accrued and unpaid interest on the Securities, if any; or 

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

(j) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the
treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock. 
 (k) Withholding on Adjustments. If, in connection with any adjustment to the Conversion
Rate as set forth in this Section 4.04, a Holder shall be deemed for U.S. federal tax purposes to have received a distribution and the Company reasonably believes it is required to collect withholding tax with respect to any such deemed
distribution, the Company may withhold from cash payments of interest in accordance with the provisions of Section 2.04 hereof or from cash and Common Stock, if any, otherwise deliverable to a Holder upon a conversion of Securities in
accordance with the provisions of Section 4.03 hereof or repurchase or redemption of a Security in accordance with the provisions of Article 3 hereof. 

Section 4.05 Other Adjustments. 

(a) Adjustments of Prices. Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices, the
Daily VWAPs or any function thereof over a span of multiple days (including, without limitation, an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change or a Redemption), the Company will
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 Effective Date,
Ex-Dividend Date or Offer Expiration Date of the event occurs, at any time during the period when such Last Reported Sale Prices, the Daily VWAPs or function thereof is to be calculated. 

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

  
 30 

 Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a
Make-Whole Fundamental Change or Notice of Redemption. 
 (a) Increase in the Conversion Rate. If (i) the Effective Date
of a Make-Whole Fundamental Change occurs prior to the Maturity Date, or (ii) the Company delivers a Notice of Redemption with respect to any or all of the Securities pursuant to Section 3.02, and, in either case, a Holder elects to
convert its Securities in connection with such Make-Whole Fundamental Change or Notice of Redemption, the Company shall, under certain circumstances, increase the Conversion Rate for the Securities so surrendered for conversion by a number of
additional shares of Common Stock (the “Additional Shares”), as described in this Section 4.06. A conversion of Securities shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental
Change if the relevant Conversion Notice is received by the Conversion Agent during the period from, and including, the Open of Business on the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on the
Business Day immediately prior to the related Fundamental Change Purchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for (x) subclause (i) of clause (2) of the definition thereof
or (y) the Adequate Cash Conversion Provisions, the 35th Trading Day immediately following the Effective Date for such Make-Whole Fundamental Change). A conversion of Securities called for Redemption pursuant to Section 3.01 shall be
deemed for these purposes to be “in connection with” a Notice of Redemption if the relevant Conversion Date occurs during the period from the Open of Business on the Redemption Notice Date to the Close of Business on the second Scheduled
Trading Day immediately preceding the related Redemption Date or, if the Company fails to pay the Redemption Price, such later date on which the Company pays the Redemption Price. For the avoidance of doubt, the Company shall increase the Conversion
Rate pursuant to this Section 4.06 in connection with a Notice of Redemption only with respect to conversions of Securities called (or deemed called, as provided in Section 4.01(b)(5)(B)) for redemption, and not of Securities not called
for redemption. Accordingly, if the Company elects to redeem less than all of the outstanding Securities pursuant to Section 3.02, Holders of Securities not called for Redemption shall not be entitled to an increased Conversion Rate for
conversions of such Securities. 
 (b) Cash Mergers. Notwithstanding anything to the contrary herein, if the consideration paid
for the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is comprised entirely of cash, then, for any conversion of Securities following the Effective Date of such Make-Whole
Fundamental Change, the Settlement Amount shall be calculated based solely on the Stock Price for such Make-Whole Fundamental Change and shall, for each $1,000 principal amount of Securities converted, be deemed to be an amount of cash equal to the
product of (i) the Conversion Rate in effect on the applicable Conversion Date (as increased by any number of Additional Shares required by this Section 4.06) multiplied by (ii) such Stock Price. In such event, the Company
will determine the Settlement Amount and pay such amount of cash to a converting Holder on the second Business Day following the applicable Conversion Date. Otherwise, the Company will settle any conversion of the Securities following the
Effective Date for a Make-Whole Fundamental Change or a Notice of Redemption in accordance with Section 4.02 hereof (but subject to Section 4.07 hereof). 

(c) Determining the Number of Additional Shares. The number of Additional Shares, if any, by which the Conversion Rate will be
increased for a Holder that converts its Securities in connection with a Make-Whole Fundamental Change or a Notice of Redemption shall be determined by reference to the table attached as Schedule A hereto, based on: 

(1) in the case of a Make-Whole Fundamental Change, the date on which the Make-Whole Fundamental occurs or becomes effective
or, in the case of a Redemption, the date of the Notice of Redemption (as used in this Section 4.06(c) only, the “Effective Date”); and 

(2) in the case of a Make-Whole Fundamental Change, the price paid (or deemed to be paid) per share of the Common Stock in the
Make-Whole Fundamental Change, as described in Schedule A, or, in the case of a Redemption, the average of the Last Reported Sale Prices per share of the Common Stock over the five consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of such Notice of Redemption, as the case may be (in each case, the “Stock Price”). 

(d) Interpolation and Limits. The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in
which case: 
 (1) If the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the
table, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and
later Effective Dates, as applicable, based on a 365-day year. 

  
 31 

 (2) If the Stock Price is greater than $47.50 per share (subject to adjustment in the same
manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased. 

(3) If the Stock Price is less than $31.54 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased. 

Notwithstanding the foregoing, in no event will the Conversion Rate be increased on account of a Make-Whole Fundamental Change or Notice of
Redemption to exceed 31.7057 shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04 hereof. 

(4) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be adjusted as of any date on which the
Conversion Rate of the Securities is otherwise required to be 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 set forth in such table shall be adjusted in the
same manner and at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04. 
 (e)
Notices. The Company shall notify the Holders of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. 

(a) Merger Events. In the case of: 

(1) any recapitalization, reclassification or change of the Common Stock (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a split, subdivision or combination for which an adjustment is made pursuant to Section 4.04(a) hereof); 

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

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

and, 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 “Merger Event,” any such stock, other securities, other property or assets, “Reference Property,” and the amount of kind of Reference Property that a
holder of one share of Common Stock (i) is entitled to receive in the applicable Merger Event or (ii) if, as a result of the applicable Merger Event, each share of Common Stock is converted into the right to receive more than a single type
of consideration (determined based in part upon any form of stockholder election), the per-share of Common Stock weighted average of the types and amounts of Reference Property received by the holders of
Common Stock that affirmatively make such an election, a “Unit of Reference Property”) then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities based on a number of shares of
the Common Stock equal to the applicable Conversion Rate will, without the consent of the Holders, be changed into a right to convert each $1,000 principal amount of Securities based on a number of Units of Reference Property equal to the applicable
Conversion Rate and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture
Act as in force at the date of execution of such supplemental indenture) providing for such change in the right to convert each $1,000 principal amount of Securities; provided, however, that the Company shall continue to determine the
form of consideration to be paid or delivered, as the case may be, pursuant to Section 4.03 and (i) any amount payable in cash upon conversion of the Securities in accordance with 

  
 32 

 
Sections 4.03 and 4.06 hereof shall continue to be payable in cash, (ii) the number of shares of Common Stock that the Company would have been required to deliver upon conversion of the
Securities in accordance with Sections 4.03 and 4.06 hereof shall instead be deliverable in Units of Reference Property and (iii) the Daily VWAP will, to the extent reasonably possible, be calculated based on the value of a Unit of Reference
Property and the definitions of Trading Day and Market Disruption Event shall be determined by reference to the components of a Unit of Reference Property; provided, further, that if the holders receive only cash in such Merger Event,
(i) the consideration due shall be solely in 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 4.06), multiplied by the price paid per share of
Common Stock in such Merger Event and (ii) settlement will occur on the second Business Day immediately following the Conversion Date. 

If the Merger 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) as contemplated by the preceding paragraph such that a Unit of Reference Property is comprised of the per-share of Common Stock
weighted average of the types and amounts of consideration actually received by the holders of the Common Stock in the Merger Event, the Company shall notify Holders of the weighted average as soon as practicable after such determination is made.

 The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 4.07. Such
supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the
board of directors of the successor Person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash or
any combination thereof) of a Person other than the successor or purchasing Person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person. 

(b) Notice of Supplemental Indentures. The Company shall cause notice of the execution of any supplemental indenture entered into
pursuant to Section 4.07(a) above to be either mailed to each Holder at the address of such Holder as it appears on the register of the Securities maintained by the Security Registrar or sent electronically to each Holder in accordance with
Applicable Procedures, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to
successive Merger Events. 
 Section 4.08 Stock Issued Upon Conversion. 

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

(b) Certain other Covenants. The Company covenants that all shares of Common Stock that may be issued upon conversion of Securities
shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other
than those created by the Holder or due to a change in registered owner). 
 The Company shall list or cause to have quoted any shares of
Common Stock to be issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is
then listed or quoted. 
 Section 4.09 Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any
time be under any duty or responsibility to any Holder of Securities to determine or calculate the Conversion Rate, to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such
adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. 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 other securities or property that may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and the Conversion Agent make no
representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or
property or cash upon the surrender of any Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections,
immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its
capacity as Conversion Agent. 

  
 33 

 Section 4.10 Notice to Holders. 

(a) Notices After Certain Actions and Events. Whenever an adjustment to the Conversion Rate becomes effective pursuant to Sections
4.04, 4.05 or 4.06 hereof, the Company will (i) file with the Trustee an Officers’ Certificate stating that such adjustment has become effective, the Conversion Rate, and the manner in which the adjustment was computed and
(ii) deliver notice to the Holder’s stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to give any such notice, or any defect therein, shall not affect the validity
of any such adjustment. 
 ARTICLE 5 

PARTICULAR COVENANTS OF THE COMPANY 

Section 5.01 Payment of Principal, Interest, Redemption Price and Fundamental Change Purchase Price. This
Section 5.01 shall replace Section 4.01 of the Base Indenture in its entirety. 
 The Company covenants and agrees that it will
cause to be paid the principal of (including the Redemption Price and the Fundamental Change Purchase Price), and accrued and unpaid interest, if any, on each of the Securities at the places, at the respective times and in the manner provided herein
and in the Securities. 
 Each of the Company and the Trustee agrees to cooperate and to provide the other, at the request of the other,
with such information as each may have in its possession to enable the determination of whether any payments pursuant to the Indenture are subject to the withholding requirements described in Section 1471(b) of the US Internal Revenue Code of
1986 (the “Code”) or otherwise imposed pursuant to Sections 1471 through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof. 

Section 5.02 Maintenance of Office or Agency. This Section 5.02 replaces Section 4.02 of the Base Indenture in its
entirety and references in the Base Indenture to Section 4.02 of the Base Indenture shall be deemed replaced with references to this Section 5.02. 

The Company will maintain in the Borough of Manhattan, The City of New York, an office of the Paying Agent, an office of the Security
Registrar and an office or agency where Securities may be surrendered for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Securities and the Indenture may be served. The
Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York. 

The Company may also from time to time designate coregistrars one or more other offices or agencies where the Securities may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms
“Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 
 The
Company hereby initially designates the Trustee as the Paying Agent, Security Registrar, Custodian, Conversion Agent and the Corporate Trust Office, which shall be in the continental United States, shall be considered as one such office or agency of
the Company for each of the aforesaid purposes. 
 With respect to any Global Security, the Corporate Trust Office of the Trustee or any
Paying Agent shall be the Place of Payment where such Global Security may be presented or surrendered for payment or conversion or for registration of transfer or exchange, or where successor Securities may be delivered in exchange therefor;
provided, however, that any such payment, conversion, presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depositary for such Global Security shall be deemed to have been effected at the Place of
Payment for such Global Security in accordance with the provisions of the Indenture.

 Section 5.03 Appointments to Fill Vacancies in Trustee’s Office. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 5.04 Provisions as to Paying Agent. This Section 5.04 shall replace Section 4.03 of the Base Indenture in
its entirety and references in the Base Indenture to Section 4.03 of the Base Indenture shall be deemed replace with references to this Section 5.04. 

(a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.04: 
 (1) that it
will hold all sums held by it as such agent for the payment of the principal of, accrued and unpaid interest, if any, on, and the Fundamental Change Purchase Price for, the Securities in trust for the benefit of the holders of the Securities; 

(2) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal of, accrued and unpaid
interest, if any, on, or the Fundamental Change Purchase Price for, the Securities when the same shall be due and payable; and 
 (3) that at
any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 

The Company shall, on or before each due date of the principal of, accrued and unpaid interest, if any, on, and Fundamental Change Purchase
Price for, the Securities, deposit with the Paying Agent a sum sufficient to pay such principal, accrued and unpaid interest, or Fundamental Change Purchase Price, as the case may be, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of any failure to take such action, provided that, if such deposit is made on the due date, such deposit must be received by the Paying Agent by 10:00 a.m., New York City time, on such date. 

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, accrued and unpaid interest, if
any, on, or Fundamental Change Purchase Price for, the Securities, set aside, segregate and hold in trust for the benefit of the holders of the Securities a sum sufficient to pay such principal, accrued and unpaid interest, if any, on or Fundamental
Change Purchase Price, as the case may be, so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal of, accrued and unpaid interest on,
or Fundamental Change Purchase Price for, the Securities when the same shall become due and payable. 
 (c) Anything in this
Section 5.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of the Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by
the Company or any Paying Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying
Agent shall be released from all further liability with respect to such sums. 
 Section 5.05 Reports. This
Section 5.05 will replace Section 5.03 of the Base Indenture in its entirety. 
 The Company will file with the Trustee, within 15
days after it is required to file the same with the SEC, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that it is required to file with the SEC pursuant to Section 13 or 15(d) of
the Exchange Act, and to otherwise comply with Section 314(a) of the Trust Indenture Act. Any such report, information or document that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed
to be delivered to the Trustee for the purposes of this Section 5.05 at the time of such filing through the EDGAR system (or such successor thereto). 

  
 35 

 Delivery of any such reports, information and documents to the Trustee shall be for
informational purposes only, and the Trustee’s receipt of such reports, information and documents shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein,
including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 

Section 5.06 Statements as to Defaults. The Company shall deliver to the Trustee, as soon as possible, and in any event
within thirty days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default, its status and the action that the Company proposes
to take with respect thereto. Such Officers’ Certificate shall also comply with any additional requirements set forth in Section 13.06 of the Base Indenture. 

Section 5.07 Supplementary Interest Notice. If Supplementary Interest is payable by the Company pursuant to Section 6.04
hereof, the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount of such Supplementary Interest that is payable and (b) the date on which such interest is payable. Unless and until a
Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Supplementary Interest is payable. If the Company has paid Supplementary Interest directly to the
Persons entitled to them, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 

Section 5.08 Covenant to Take Certain Actions. Before taking any action which would cause an adjustment to the Conversion
Rate such that the Conversion Price per share of Common Stock issuable upon conversion of the Securities would be less than the par value of the Common Stock, the Company shall take all corporate actions that may, in the opinion of its counsel, be
necessary so it may validly and legally issue shares of Common Stock at such adjusted Conversion Rate. 
 ARTICLE 6 

REMEDIES 

Section 6.01 Amendments to the Base Indenture. 

(a) The Holders shall not have the benefit of Article VI of the Base Indenture and, with respect to the Securities, this Article 6
supersedes Article VI of the Base Indenture in its entirety. 
 (b) The references to Section 6.01(a)(4) and
Section 6.01(a)(5) in Section 7.06(c) of the Base Indenture is, with respect to the Securities, hereby deemed replaced by a reference to Section 6.02(h) and Section 6.02(i) hereof, respectively. 

(c) The reference to Section 6.01(a)(3) in Section 11.03(b) of the Base Indenture is, with respect to the Securities, hereby deemed
replaced by a reference to Section 6.02(c) hereof. 
 Section 6.02 Events of Default. Each of the following events (and
only the following events) shall be an “Event of Default” wherever used with respect to the Securities: 
 (a) failure to
pay the principal of any Security (including the Fundamental Change Purchase Price) when due and payable on the Maturity Date, upon required repurchase, upon Redemption, upon declaration of acceleration or otherwise; 

(b) failure to pay interest when due and such failure continues for 30 days; 

(c) failure to observe or perform any other covenant contained in the Securities or the Indenture and such failure continues for 60 days after

 (f) failure by the Company to issue a notice in accordance with the provisions of

 (g) failure
by the Company to pay beyond any applicable grace period, or the acceleration of, indebtedness of the Company or any of the Company’s Subsidiaries in an aggregate amount greater than $55.0 million (or its foreign currency equivalent at the
time); 
 (h) the Company shall commence a voluntary case or other proceeding seeking the liquidation, reorganization or other relief with
respect to the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any substantial
part of the Company’s property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the
benefit of creditors, or shall fail generally to pay its debts as they become due; and 
 (i) an involuntary case or other proceeding shall
be commenced against the Company seeking liquidation, reorganization or other relief with respect to the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of the Company or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of thirty 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(h) or Section 6.02(i)), unless the principal of all of the Securities shall have already become due and payable, either
the Trustee or the holders of at least 25% in aggregate principal amount of the Securities, by notice in writing to the Company (and to the Trustee if given by the Holders), may declare the unpaid principal of and accrued interest, if any, due and
payable immediately. If an Event of Default specified in Section 6.02(h) or Section 6.02(i) occurs and is continuing, then all unpaid principal amounts and accrued interest, if any, shall immediately become due and payable, without
any action by the Trustee or any Holder of Securities. 
 Section 6.04 Supplementary Interest. 

(a) Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating
to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that it is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act, or (ii) the Company’s failure to comply with Section 5.05 hereof (a “Reporting Event of Default”), will, for the first 365 days after the occurrence of such an Event of Default, consist exclusively of
the right to receive additional interest on the Securities (the “Supplementary Interest”) at a rate equal to (i) 0.25% per annum of the Outstanding principal amount of the Securities for each day during the 185-day period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum of the Outstanding principal amount of
the Securities for each day during the 180-day period on which such Event of Default is continuing beginning on, and including the 186th day on which such
Event of Default is continuing. If the Company so elects, such Supplemental Interest will be payable in the same manner and on the same dates as the stated interest payable on the Securities. On the 366th day after such Event of Default (if the
Reporting Event of Default is not cured or waived prior to such 366th day), the Securities will be subject to acceleration pursuant to Section 6.03. The provisions of this Section 6.04 will not affect the rights of Holders of Securities in
the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Company does not elect to pay the Supplemental Interest following an Event of Default in accordance with this Section 6.04 or
the Company elected to make such payment but do not pay the Supplemental Interest when due, the Securities will be immediately subject to acceleration as provided in Section 6.03. 

(b) In order to elect to pay the Supplemental Interest as the sole remedy during the first 365 days after the occurrence of an Reporting Event
of Default, the Company must notify all Holders of Securities, the Trustee and the Paying Agent of such election prior to the beginning of such 365-day period. Upon the Company’s failure to timely give
such notice, the Securities will be immediately subject to acceleration as provided in Section 6.03. 

  
 37 

 Section 6.05 Waiver of Past Defaults. The Trustee may withhold notice to
the Holders of Securities of any Default or Event of Default, except a Default or Event of Default relating to the payment of principal or interest or the failure to deliver the consideration due upon conversion, if it determines that withholding
such notice is in the Holders’ interest. The Holders of a majority in principal amount of the Securities may waive any Default or Event of Default with respect to the Securities and its consequences, except a continuing Default or Event of
Default in the payment of principal or interest on the Securities or the failure to deliver the consideration due upon conversion. Any such waiver shall cure such Default or Event of Default. 

Section 6.06 Control by Majority. At any time, the Holders of a majority of the aggregate principal amount of the then
Outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee, with respect to the Securities, provided that:

 (a) the Trustee may refuse to follow any direction that conflicts with law or the Indenture; 

(b) the Trustee may take any other action deemed proper by it which is not inconsistent with such direction; and 

(c) subject to the Trustee’s duties under the Trust Indenture Act, the Trustee need not take any action that might involve it in personal
liability or might be unduly prejudicial to the Holders not involved in the proceeding. 
 Prior to taking any action hereunder, the Trustee
will be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action. 

Section 6.07 Limitation on Suits. A Holder of the Securities will only have the right to institute a proceeding under the
Indenture or to appoint a receiver or trustee, or to seek other remedies if: 
 (a) the Holder has delivered to the Trustee written notice
that an Event of Default has occurred and is continuing with respect to the Securities; 
 (b) the Holders of at least 25% of the aggregate
principal amount of the Securities have made written request, and such Holders have offered indemnity to the Trustee satisfactory to the Trustee to institute such proceedings as Trustee; and 

(c) the Trustee does not institute such proceeding, and does not receive from the Holders of a majority in the aggregate principal amount of
the Outstanding Securities other conflicting directions within 60 days after such notice, request and offer. 
 A Holder may not use the
Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of the Indenture by a Holder is
unduly prejudicial to such other Holders. 
 Section 6.08 Rights of Holders to Receive Payment and to Convert. Notwithstanding
anything to the contrary elsewhere in the Indenture, the right of any Holder to receive payment of the principal of, interest on, Fundamental Change Purchase Price for, its Securities, on or after the respective due date, and to convert its
Securities and receive payment or delivery of the consideration due with respect to such Securities in accordance with Article 4 hereof, or to bring suit for the enforcement of any such payment or conversion rights, will not be impaired or affected
without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof. 
 Section 6.09
Collection of Indebtedness; Suit for Enforcement by Trustee. If an Event of Default specified in Section 6.02(a), 6.02(b) or 6.02(c) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own
name and as trustee of an express trust against the Company for the whole amount of principal of, interest on, Fundamental Change Purchase Price for, and the amount of cash or the combination of cash and shares of Common Stock, if any, as the case
may be, due upon the conversion of, the Securities, as the case may be, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, as well as any other amounts that may be due under Section 7.06 of the Base Indenture. 

Section 6.10 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims
under the Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall
be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders in respect of which such judgment has been recovered. 

  
 38 

 Section 6.11 Trustee May File Proofs of Claim. The
Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its
property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 of the Base Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 of the Base Indenture out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and
is paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.12 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under the Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such
proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding
had been instituted. 
 Section 6.13 Rights and Remedies Cumulative. Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.07 of the Base Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 6.14 Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to
the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in the Indenture) or by the Holders, as the case may be. 

Section 6.15 Priorities. If the Trustee collects any money pursuant to this Article 6, it will pay out the money in the
following order: 
 FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.06 of the Base Indenture, including
payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, Fundamental Change Purchase Price
for, and any cash due upon conversion of, any Security, without preference or priority of any kind, according to such amounts due and payable on all of the Securities; and 

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs. 

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.15. If the Trustee so
fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment.

  
 39 

 Section 6.16 Undertaking for Costs. All parties to the Indenture agree, and
each Holder, by such Holder’s acceptance of a Security, 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, 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, however, that the provisions of this Section 6.16 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 aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price for, any Security on or after the due date expressed or provided for in the Indenture or to any suit for the enforcement of
the right to convert any Security in accordance with the provisions of Article 4 hereof. 
 Section 6.17 Waiver of Stay,
Extension and Usury Laws. The Company covenants that, to the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury
law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been
enacted. 
 Section 6.18 Notices from the Trustee. Notwithstanding anything to the contrary in the Base Indenture, whenever
a Default occurs and is continuing and in the case of a payment Default is known to the Trustee, or for all other Defaults for which a Responsible Officer of the Trustee received written notice at the Corporate Trust Office, the Trustee must deliver
notice of such Default to the Holders within 90 days after the date on which such Default first occurred. Except in the case of a Default in the payment of the principal of, interest on, or Fundamental Change Purchase Price for, any Security or of a
Default in the payment or delivery, as the case may be, of the consideration due upon conversion of a Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders. 

ARTICLE 7 

SATISFACTION AND DISCHARGE 

Section 7.01 Inapplicability of Provisions of Base Indenture; Satisfaction and Discharge of the Indenture. Article XI of the
Base Indenture shall not apply with respect to the Securities. The provisions set forth in this Article 7 shall, with respect to the Securities, supersede in their entirety Article XI of the Base Indenture. The references to
Section 11.05 in Section 4.03(c) and Section 7.05 of the Base Indenture are, with respect to the Securities, hereby deemed replaced by a reference to Section 7.03 hereof. 

When (a) the Company shall deliver to the Security Registrar for cancellation all Securities theretofore authenticated (other than any
Securities that have been destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Securities not theretofore canceled or
delivered to the Trustee for cancellation shall have (1) become due and payable (whether on the Maturity Date, on any Fundamental Change Purchase Date or Redemption Date, upon conversion or otherwise) and/or (2) been converted (and the
related Settlement Amounts have been determined) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, an amount of cash or the combination of cash and shares of Common Stock, if any, as the case may be
(solely to settle amounts due with respect to outstanding conversions), sufficient to pay all amounts due on all of such Securities (other than any Securities that shall have been mutilated, destroyed, lost or stolen and in lieu of or in
substitution for which other Securities shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation and/or settle all conversions, as the case may be, including principal and interest due,
accompanied, except in the event the Securities are due and payable solely in cash at the Maturity Date or upon an earlier Fundamental Change Purchase Date, by a verification report as to the sufficiency of the deposited amount from a firm of
nationally recognized independent certified accountants or other financial professionals, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then the Indenture shall cease to be of further effect
(except as to (i) rights hereunder of Holders to receive all amounts owing upon the Securities and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee
and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of the Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee, including
the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with the Indenture or the Securities. 

  
 40 

 Section 7.02 Deposited Monies to Be Held in Trust by Trustee. Subject to
Section 7.04 hereof, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 7.01 hereof shall be held in trust for the sole benefit of the Holders of the Securities, and such monies and shares of
Common Stock shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Securities for the payment or settlement of which
such monies or shares of Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any. 

Section 7.03 Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of the Indenture, all monies and shares
of Common Stock, if any, then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with
respect to such monies and shares of Common Stock. 
 Section 7.04 Return of Unclaimed Monies. Subject to the requirements
of applicable law, any monies and shares of Common Stock deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Securities and not applied but remaining unclaimed by the Holders of the Securities for two
years after the date upon which the principal of or interest, if any, on such Securities, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall
thereupon cease with respect to such monies and shares of Common Stock; and the Holder shall thereafter look only to the Company for any payment or delivery that such Holder may be entitled to collect unless an applicable abandoned property law
designates another person. 
 Section 7.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money
or shares of Common Stock in accordance with Section 7.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the
Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in
accordance with Section 7.02; provided, however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Security following the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent.

With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities affected by such supplemental
indenture, including without limitation, consents obtained in connection with a purchase of, or tender or exchange offer for, Securities and by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board
Resolution, and the Trustee may 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 of modifying in any manner the

(k) modify any of the above provisions. 

It shall not be necessary for any Act or consent of Holders under this Section 8.02 to approve the particular form of any proposed

any indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders
remain Holders after such record date; provided that, unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent
previously given shall automatically and without further action by any Holder be cancelled and of no further effect. 
 Section 8.03
Notice of Amendment or Supplement. After an amendment or supplement under this Article 8 becomes effective, the Company shall send to the Holders a notice briefly describing such amendment or supplement, unless a Current Report on

 ARTICLE 9 

MISCELLANEOUS 

Section 9.01 Effect on Successors and Assigns. Notwithstanding Section 2.09 of the Base Indenture, all agreements of the
Company, the Trustee, the Security Registrar, the Paying Agent and the Conversion Agent in the Indenture and the Securities will bind their respective successors. 

Section 9.02 Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL
INDENTURE AND THE SECURITIES. 
 Section 9.03 No Security Interest Created. Nothing in the Indenture or in the Securities,
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 9.04 Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust
Indenture Act that is required under such Act to be a part of and govern the Indenture, the latter provision shall control. If any provision of the Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified
or excluded, the latter provision shall be deemed to apply to the Indenture as so modified or to be excluded, as the case may be. 

Section 9.05 Benefits of Supplemental Indenture. Notwithstanding anything to the contrary in Section 2.09 of the Base
Indenture, nothing in this Supplemental Indenture or in the Securities, expressed or implied, will give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any Authenticating Agent, any Security Registrar or their
successors hereunder or the Holders of the Securities, any benefit or any legal or equitable right, remedy or claim under this Supplemental Indenture. 

Section 9.06 Amendments to Base Indenture. 

(a) Section 7.02 of the base indenture is, with respect to the Securities, hereby modified by deleting all text beginning with and following
full paragraph (j) in such Section 7.02 and replacing it with the below text: 
 (j) Whenever in the administration
of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may request and, in the
absence of bad faith on its part, conclusively rely upon an Officers’ Certificate or Opinion of Counsel and the Trustee shall not be liable for any action it takes or omits in good faith in reliance on such Officers’ Certificate of Opinion
of Counsel; 

  
 43 

 (k) In no event shall the Trustee be responsible or liable for special,
indirect, punitive or consequential loss or damages of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of
action; and 
 (l) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree
in writing with the Company. 
 In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of
Default except (1) any Event of Default occurring pursuant to Sections 6.01(a)(1) and 6.01(a)(2) or (2) any Default or Event of Default of which a Responsible Officer of the Trustee shall have received written notification at the Corporate
Trust Office in the manner set forth in this Indenture. Delivery of reports, information and documents to the Trustee under Section 5.03 is for informational purposes only and the information and the Trustee’s receipt of the foregoing
shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee is entitled to
rely exclusively on an Officers’ Certificate). 
 (b) The second paragraph of Section 13.03 of the Base Indenture is, with respect
to the Securities, hereby deemed replaced by the below paragraph: 
 The Trustee and the Conversion Agent shall have the
right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to the Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the
Trustee and the Conversion Agent an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency
certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee and the Conversion Agent Instructions using Electronic Means and the Trustee and the Conversion Agent
in its discretion elects to act upon such Instructions, the Trustee’s and the Conversion Agent’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee and the Conversion Agent
cannot determine the identity of the actual sender of such Instructions and that the Trustee and the Conversion Agent shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency
certificate provided to the Trustee and the Conversion Agent have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and the Conversion Agent
and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. Neither the Trustee nor
the Conversion Agent shall be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s or Conversion Agent’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or
are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee and the Conversion Agent, including without limitation the risk
of the Trustee and the Conversion Agent acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of
transmitting Instructions to the Trustee and the Conversion Agent and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in
connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee and the Conversion Agent immediately upon learning
of any compromise or unauthorized use of the security procedures. “Electronic Means” shall mean the following communications methods: e-mail, facsimile transmission, secure electronic
transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee and the Conversion Agent, or another method or system specified by the Trustee and the Conversion Agent as available for use in
connection with its services hereunder.
 Section 9.07 Calculations. Except as otherwise provided in the Indenture, the
Company shall be responsible for making all calculations called for under the Securities. These calculations include, but are not limited to, determinations of the Stock Price or Trading 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 Securities and the Conversion Rate. The Company shall make all these calculations in good faith and, absent manifest error, the
Company’s calculations shall be final and binding on Holders of Securities, the Trustee and the Conversion Agent. The Company shall provide a schedule of its calculations to each of the Trustee and the Conversion Agent, and each of the
Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder upon the request of that
Holder at the sole cost and expense of the Company. 

  
 44 

 Whenever the Company is required to calculate the Conversion Rate, the Company will do so to
the nearest 1/10,000th of a share of Common Stock. 
 Section 9.08 Execution in Counterparts and Electronic Execution. This
Supplemental Indenture may be executed in any number of counterparts, each of which shall be deemed to be an original, but such counterparts shall, together, constitute one and the same instrument. The words “execution,” signed,”
“signature,” and words of like import in this Indenture or in any other certificate, agreement or document related to this Indenture or in the Securities shall include images of manually executed signatures transmitted by facsimile or
other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic
records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or
use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, and any other
applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code. This Supplemental Indenture shall be valid, binding, and enforceable against a party only when executed and
delivered by an authorized individual on behalf of the party by means of (i) any electronic signature permitted by the federal Electronic Signatures in Global and National Commerce Act, state enactments of the Uniform Electronic Transactions
Act, and/or any other relevant electronic signatures law, including relevant provisions of the Uniform Commercial Code/UCC (collectively, “Signature Law”); (ii) an original manual signature; or (iii) a faxed, scanned, or
photocopied manual signature. Each electronic signature or faxed, scanned, or photocopied manual signature shall for all purposes have the same validity, legal effect, and admissibility in evidence as an original manual signature. Each party hereto
shall be entitled to conclusively rely upon, and shall have no liability with respect to, any faxed, scanned, or photocopied manual signature, or other electronic signature, of any party and shall have no duty to investigate, confirm or otherwise
verify the validity or authenticity thereof. For avoidance of doubt, original manual signatures shall be used for execution or indorsement of writings when required under the UCC or other Signature Law due to the character or intended character of
the writings. 
 Section 9.09 Notices. The Company or the Trustee, by notice given to the other in the manner provided in
Section 13.03 of the Base Indenture, may designate additional or different addresses for subsequent notices or communications. 

Notwithstanding anything to the contrary in the Base Indenture, whenever the Company is required to deliver notice to the Holders, the Company
will, by the date it is required to deliver such notice to the Holders, deliver a copy of such notice to the Trustee, the Paying Agent, the Security Registrar and the Conversion Agent. Each notice to the Trustee, the Paying Agent, the Security
Registrar and the Conversion Agent shall be sufficiently given if in writing and mailed, first-class postage prepaid to the address most recently sent by the Trustee, the Paying Agent, the Security Registrar or the Conversion Agent, as the case may
be, to the Company. 
 Section 9.10 Ratification of Base Indenture. The Base Indenture, as supplemented and as amended,
with respect to the Securities, 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 provided. For the
avoidance of doubt, each of the Company and each Holder of Securities, by its acceptance of such Securities, acknowledges and agrees that all of the rights, privileges, protections, immunities and benefits afforded to the Trustee under the Base
Indenture are deemed to be incorporated herein, and shall be enforceable by the Trustee hereunder, in each of its capacities hereunder as if set forth herein in full. 

Section 9.11 The Trustee. The recitals in this Supplemental Indenture are made by the Company only and not by the Trustee,
and all of the provisions contained in the Base Indenture in respect of the rights, privileges, immunities, powers and duties of the Trustee shall be applicable in respect of the Securities and of this Supplemental Indenture as fully and with like
effect as set forth in full herein. 
 Section 9.12 No Recourse Against Others. No director, officer, employee,
incorporator or stockholder of the Company shall have any liability for any obligations of the Company under the Securities, the Indenture or any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder,
by accepting a Security, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.

BLACKSTONE MORTGAGE TRUST, INC. 

5.50% Convertible Senior Notes due 2027 

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued under a
Senior Debt Indenture dated as of November 25, 2013 (herein called the “Base Indenture”), and as further supplemented by the Fourth Supplemental Indenture, dated as of March 29, 2022 (herein called the
“Supplemental Indenture” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”) by and between the Company and The Bank of New York Mellon Trust Company, N.A., herein called the
“Trustee”, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the
terms upon which the Securities are, and are to be, authenticated and delivered. This Security is not subject to redemption at the option of the Company prior to the Maturity Date except in accordance with the Indenture and does not benefit
from a sinking fund. 
 As provided in and subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change, the
Holder of this Security will have the right, at such Holder’s option, to require the Company to purchase this Security, or any portion of this Security such that the principal amount of this Security that is not purchased equals $1,000 or an
integral multiple of $1,000 in excess thereof, on the Fundamental Change Purchase Date at a price equal to the Fundamental Change Purchase Price for such Fundamental Change Purchase Date. 

As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at its option (i) 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 December 15, 2026, and (ii) on or after December 15, 2026, at any time prior to the
Close of Business on the second Scheduled Trading Day immediately preceding the Stated Maturity, to convert this Security or a portion of this Security such that the principal amount of this Security that is not converted equals $1,000 or an
integral multiple of $1,000 in excess thereof, into an amount of cash, shares of Common Stock or a combination of cash and shares of Common Stock, as the case may be, determined in accordance with Article 4 of the Supplemental Indenture. 

As provided in and subject to the provisions of the Indenture, the Company will make all payments in respect of the Redemption Price, the
Fundamental Change Purchase Price for, and the principal amount of, this Security to the Holder that surrenders this Security to the Paying Agent to collect such payments in respect of this Security. The Company will pay cash amounts in money
of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be effected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at
the time Outstanding, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by
the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security. 
 As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee
written notice of a continuing Event of Default with respect to the Security, the Holders of not less than 25% in principal amount of the Securities at the time Outstanding shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this
Security for the enforcement of any payment of principal hereof or interest hereon or amounts due upon conversion on or after the respective due dates expressed herein. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of (including the Fundamental Change Purchase Price), interest on and the amount of cash, shares of Common Stock or combination of cash and shares of
Common Stock, as the case may be, due upon conversion of, this Security at the time, place and rate, and in the coin and currency, herein prescribed. 

 As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or its attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Securities are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000 in excess
thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Securities are exchangeable for a like aggregate principal amount of Securities and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same. 
 Prior to due presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or Trustee may treat the Person in whose name the Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary. 
 No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other similar governmental charge payable in connection therewith. 

All defined terms used in this Security that are defined in the Indenture shall have the meanings assigned to them in the Indenture. If
any provision of this Security limits, qualifies or conflicts with a provision of the Indenture, such provision of the Indenture shall control.
