The Company shall at all times when any Securities are outstanding maintain an office or agency in The City of New York, which may be the
office of the Trustee in such city, to act as Paying Agent, Conversion Agent, Security Registrar and Bid Solicitation Agent with respect to the Securities. If the Company fails to maintain a Security Registrar, Paying Agent, Conversion Agent or Bid

Section 3.5 of the Base Indenture for purposes of the Securities. 
 The Company shall not be required to transfer or exchange any
Security surrendered for conversion. 
 2.05 OUTSTANDING SECURITIES. 

If the Paying Agent (other than the Company) holds on an Option Purchase Date, Redemption Date, Fundamental Change Repurchase Date or Maturity
Date, money sufficient to pay the aggregate Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, as the case may be, with respect to all Securities to be redeemed, purchased or paid upon Purchase at
Holder’s Option, Redemption, Repurchase Upon Fundamental Change or maturity, as the case may be, in each case plus, if applicable, accrued and unpaid interest, if any, payable as herein provided upon Purchase at Holder’s Option,
Redemption, Repurchase Upon Fundamental Change or maturity, then (unless there shall be a Default in the payment of such aggregate Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal amount, or of such accrued
and unpaid interest), except as otherwise provided herein, on and after such date such Securities shall be 

  
 -10- 

 
deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed paid whether or not such Securities are delivered to the Paying Agent.
Thereafter, all rights of the Holders with respect to such Securities shall terminate with respect to such Securities, other than the right to receive the Option Purchase Price, Redemption Price, Fundamental Change Repurchase Price or principal
amount, as the case may be, plus, if applicable, such accrued and unpaid interest, in accordance with this Indenture. 
 If a Security is
converted in accordance with Article X, then, from and after the Conversion Date for such conversion, such Security shall cease to be outstanding, and interest, if any, shall cease to accrue on such Security unless there
shall be a Default in the payment or delivery of the Conversion Consideration payable hereunder upon such conversion; provided, however, that an exchange in lieu of conversion in accordance with Section 10.14
shall not be deemed to be a conversion for purposes of this paragraph. 
 For purposes of the Securities, this
Section 2.05 shall supersede and modify the definition of “Outstanding” under the Base Indenture to the extent this Section 2.05 is inconsistent or conflicts with such definition. 

2.06 INTEREST PAYMENT AND RECORD DATES. 

The Interest Payment Dates for the Securities shall be May 1 and November 1 of each calendar year, beginning with, and including,

registered, as shown on the Security Registrar’s books, at the close of business on the Regular Record Date immediately preceding such Interest Payment Date. Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities, the first paragraph of Section 3.07 of the Base Indenture shall not apply to the Securities.

immediately available on such date, sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Purchase Date or Fundamental Change Repurchase Date, as the case may be, in a timely manner which
permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, 

  
 -11- 

 
Maturity Date, Redemption Date, Option Purchase Date or Fundamental Change Repurchase Date, as the case may be. For purposes of the Securities, the terms “at or prior to 10:00 A.M., New
York City time, on” shall be deemed to replace the first instance of the words “on or before” in the first paragraph, and the words “on or prior to” in the second paragraph, of Section 10.03 of the Base Indenture. 

2.09 BOOK-ENTRY PROVISIONS FOR GLOBAL
SECURITIES. 
 (A) The Global Securities initially shall (i) be registered in the name of the Depositary for the
Securities or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear legends as required by this Supplemental Indenture. 

Members of, or participants in, the Depositary for the Securities (“Participants”) shall have no rights under this Indenture
with respect to any Global Security held on their behalf by such Depositary, or the Trustee as its custodian, or under the Global Security, and such Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as
the absolute owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification,
proxy or other authorization furnished by such Depositary or impair, as between such Depositary and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 

(B) Transfers of Global Securities shall be limited to transfers in whole, but not in part, to the Depositary for the Securities, its
successors or their respective nominees. Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, the ninth (9th) paragraph of Section 3.05 of the Base Indenture shall not apply to the
Securities. Beneficial interests in a Global Security, as identified by such Depositary and the Participants, may be exchanged for Physical Securities, in registered form, in exchange for their beneficial interests in Global Securities only if
(i) such Depositary notifies the Company that such Depositary is unwilling or unable to continue as depositary for such Global Security and a successor Depositary is not appointed by the Company within ninety (90) days after receiving such
notice; (ii) such Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and a successor Depositary is not appointed by the Company within ninety (90) days after becoming aware that the
Depositary has so ceased to be a “clearing agency” registered under Section 17A of the Exchange Act; (iii) the Company, in its sole discretion, determines that such Global Security shall be exchangeable for Physical Securities,
in registered form, and the Company notifies the Trustee of the same; or (iv) an Event of Default with respect to the Securities represented by such Global Security shall have occurred and be continuing. This Section 2.09(B) shall
replace the ninth (9th) and tenth (10th) paragraphs of Section 3.05 of the Base Indenture for purposes of the Securities. 

(C) In connection with the transfer of a Global Security in its entirety to beneficial owners pursuant to
Section 2.09(B), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon written instructions from the Company authenticate and
deliver, to each beneficial owner, identified by the Depositary or the Participants, of such Global Security, in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized
denominations. 

  
 -12- 

 (D) The Holder of any Global Security may grant proxies and otherwise authorize any
Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Securities. 

2.10 RANKING. 

The indebtedness of the Company arising under or in connection with this Supplemental Indenture and every outstanding Security issued under
this Supplemental Indenture from time to time constitutes and will constitute a senior unsecured obligation of the Company, ranking equally with other existing and future senior unsecured indebtedness of the Company and ranking senior to any
existing or future subordinated indebtedness of the Company. 
 2.11 ADDITIONAL
SECURITIES. 
 The Company may, without the consent of the Holders and notwithstanding Sections 2.01
and 2.02 hereof, reopen the Securities and issue, in an unlimited aggregate principal amount, additional Securities hereunder with the same terms and conditions (except for any difference in the issue price therefor and interest accrued
prior to the date of issuance thereof) and with the same CUSIP number as the Securities initially issued hereunder, which additional Securities will form the same series with the Securities initially issued hereunder, provided that such
additional Securities constitute the same issue as the Securities initially issued hereunder for U.S. federal income tax purposes. The Securities initially issued hereunder and any such additional Securities will rank equally and ratably and would
be treated as a single series of debt securities for all purposes under the Indenture.

any Securities pursuant to a Redemption if the principal amount of the Securities has been accelerated pursuant to Section 6.02 and such acceleration shall not have been rescinded on or before the applicable Redemption

upon Redemption on all Securities to be redeemed on such Redemption Date. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose.

Company or the Trustee so requires, 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 its attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in
aggregate principal amount equal to the portion of such Security not submitted for Redemption.

payable as herein provided upon a Purchase at Holder’s Option; 
 (iv) that Securities must be surrendered, or
transferred by book-entry transfer, to the Paying Agent to collect payment of the Option Purchase Price (except that, if the Option Purchase Date is after a Regular Record Date and on or before the immediately following Interest Payment Date, then

will cease to accrue, and all rights of the Holders with respect to such Securities shall terminate, other than the right to receive, in accordance herewith, the consideration payable as herein provided upon a Purchase at Holder’s Option; and

 (ix) the CUSIP number or numbers, as the case may be, of the Securities. 

At the Company’s request, upon reasonable prior notice, the Trustee shall mail such Option Purchase Notice in the Company’s name and
at the Company’s expense; provided, however, that the form and content of such Option Purchase Notice shall be prepared by the Company. 

No failure of the Company to give an Option Purchase Notice shall limit any Holder’s right to exercise its rights to require the Company

 -20- 

 (C) Subject to the provisions of this Section 3.12, the
Company shall pay, or cause to be paid, the Option Purchase Price with respect to each Security subject to Purchase at Holder’s Option to the Holder thereof as promptly as practicable, but in no event later than the later of the applicable
Option Purchase Date and the time such Security (together with all necessary endorsements) is surrendered or transferred, by book-entry, to the Trustee or the Paying Agent (except that, if the Option Purchase Date is after a Regular Record Date and
on or before the immediately following Interest Payment Date, then accrued and unpaid interest on such Securities to, but excluding, such Interest Payment Date will be paid, on such Interest Payment Date, to the Holder(s) of record of such
Securities at the close of business on such Regular Record Date without any requirement to surrender or transfer such Securities to the Paying Agent). 

(D) Prior to 10:00 A.M., New York City time on the applicable Option Purchase Date, the Company shall deposit with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 10.03 of the Base Indenture) money, in funds immediately available on the applicable Option Purchase Date, sufficient to pay the
consideration payable as herein provided for all of the Securities that are to be purchased by the Company on such Option Purchase Date pursuant to such Purchase at Holder’s Option. The Paying Agent shall return to the Company, as soon as

 (E) Once the Purchase Notice has been duly delivered in accordance with this
Section 3.12, the Securities to be purchased pursuant to the Purchase at Holder’s Option shall, on the applicable Option Purchase Date, become due and payable in accordance herewith, and, on and after such date (unless
there shall be a Default in the payment of the consideration payable as herein provided upon a Purchase at Holder’s Option), except as otherwise herein provided, such Securities shall cease to bear interest, and all rights of the Holders with
respect to such Securities shall terminate, other than the right to receive, in accordance herewith, the such consideration. 

(F) Securities with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.12
may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.12 or if there shall be a

 (G) If any Security
subject to Purchase at Holder’s Option shall not be paid in accordance herewith, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the
principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. 
 (H) Any Security
which is to be submitted for Purchase at Holder’s Option only in part shall be delivered pursuant to this Section 3.12 (with, if the Company or the Trustee so requires, 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 its attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the
Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not submitted for
Purchase at Holder’s Option. 

  
 -21- 

 (I) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities to the contrary, there shall be no purchase of any Securities pursuant to this Section 3.12 if the principal amount of the Securities has been accelerated pursuant to Section 6.02 and such
acceleration shall not have been rescinded on or before the applicable Option Purchase Date. The Paying Agent will promptly return to the respective Holders thereof any Securities tendered to it for Purchase at Holder’s Option during the
continuance of such an acceleration. 
 (J) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities to the contrary, if the option granted to Holders to require the purchase of the Securities on the applicable Option Purchase Date is determined to constitute a tender offer, the Company shall comply with all applicable tender offer rules
under the Exchange Act, including Rule 13e-4 and Regulation 14E thereunder, and with all other applicable laws, and will file a Schedule TO or any other schedules required under the Exchange Act or any
other applicable laws. 
 3.13 REPURCHASE AT OPTION OF
HOLDER UPON A FUNDAMENTAL CHANGE. 
 (A) In the event any
Fundamental Change shall occur, each Holder of Securities shall have the right (the “Fundamental Change Repurchase Right”), at such Holder’s option, to require the Company to repurchase all of such Holder’s Securities (or
portions thereof that are integral multiples of $1,000 in principal amount), on a date selected by the Company (the “Fundamental Change Repurchase Date”), which Fundamental Change Repurchase Date shall be no later than thirty five
(35) days, nor earlier than twenty (20) Business Days, after the date the Fundamental Change Notice (as defined below) is mailed in accordance with Section 3.13(B), at a price, payable in cash, equal to the
Fundamental Change Repurchase Price for such Securities, upon: 
 (i) delivery to the Trustee or any Paying Agent, by such
Holder, at any time prior to the close of business on the Business Day immediately preceding the applicable Fundamental Change Repurchase Date, of a Purchase Notice, in the form set forth in the Securities or any other form of written notice

 (ii) delivery or book-entry transfer to the Trustee or a Paying Agent, at
any time after delivery of such Purchase Notice, of such Securities (together with all necessary endorsements), such delivery or transfer being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor (except that, if
the Fundamental Change Repurchase Date is after a Regular Record Date and on or before the immediately following Interest Payment Date, then accrued and unpaid interest on such Securities to, but excluding, such Interest Payment Date will be paid,
on such Interest Payment Date, to the Holder(s) of record of such Securities at the close of business on such Regular Record Date without any requirement to surrender such Securities to the Paying Agent). 

If such Securities are held in book-entry form through the Depositary, the Purchase Notice, and each withdrawal of any Purchase Notice, shall
comply with applicable procedures of the Depositary. 
 Upon such delivery of Securities to the Company (if it is acting as its own Paying
Agent) or such Paying Agent, such Holder shall be entitled to receive from the Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit evidencing such delivery. 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, any Holder that has delivered
the Purchase Notice contemplated by this Section 3.13(A) to the Trustee or any Paying Agent shall have the right to withdraw such Purchase Notice by delivery, at any time prior to the close of business on the Business Day
immediately preceding the applicable Fundamental Change Repurchase Date, of a written notice of withdrawal to the Trustee or any Paying Agent, which notice shall contain the information specified in Section 3.13(B)(xi).

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

 (B) Within fifteen (15) Business Days after the occurrence of a Fundamental Change, the Company shall mail, or cause to be
mailed, to each Holder of the Securities, at its address shown on the Security Registrar’s books, and to beneficial owners as required by applicable law, a notice (the “Fundamental Change Notice”) of the occurrence of such
Fundamental Change and the Fundamental Change Repurchase Right arising as a result thereof. The Company shall deliver a copy of the Fundamental Change Notice to the Trustee and shall cause a copy to be published at the expense of the Company in a
press release disseminated through Dow Jones & Company, Inc. or Bloomberg Business News or other similarly broad public medium that is customary for such press releases. 

Each Fundamental Change Notice shall state: 

(i) the events causing the Fundamental Change; 

(ii) the date of such Fundamental Change; 

(iii) the Fundamental Change Repurchase Date; 

  
 -23- 

 (iv) the date by which the Fundamental Change Repurchase Right must be
exercised; 
 (v) the Fundamental Change Repurchase Price; 

(vi) the names and addresses of the Paying Agent and the Conversion Agent; 

(vii) a description of the procedures which a Holder must follow to exercise the Fundamental Change Repurchase Right; 

(viii) that Securities must be surrendered, or transferred by book-entry transfer, to the Paying Agent to collect payment of
the Fundamental Change Repurchase Price (except that, if the Fundamental Change Repurchase Date is after a Regular Record Date and on or before the immediately following Interest Payment Date, then accrued and unpaid interest on such Securities to,
but excluding, such Interest Payment Date will be paid, on such Interest Payment Date, to the Holder(s) of record of such Securities at the close of business on such Regular Record Date without any requirement to surrender or transfer such
Securities to the Paying Agent); 
 (ix) that the Fundamental Change Repurchase Price for any Security as to which a Purchase
Notice has been given and not withdrawn will be paid as promptly as practicable, but in no event later than the later of such Fundamental Change Repurchase Date or the time of delivery of the Security as described in clause
(viii) above (except that, if the Fundamental Change Repurchase Date is after a Regular Record Date and on or before the immediately following Interest Payment Date, then accrued and unpaid interest on such Securities to, but
excluding, such Interest Payment Date will be paid, on such Interest Payment Date, to the Holder(s) of record of such Securities at the close of business on such Regular Record Date and the Fundamental Change Repurchase Price will not include such
accrued and unpaid interest); 
 (x) that, except as otherwise provided herein, on and after such Fundamental Change
Repurchase Date (unless there shall be a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change), interest on Securities subject to Repurchase Upon Fundamental Change will cease to accrue, and
all rights of the Holders with respect to such Securities shall terminate, other than the right to receive, in accordance herewith, the consideration payable as herein provided upon Repurchase Upon Fundamental Change; 

(xi) that a Holder will be entitled to withdraw its election in the Purchase Notice if the Trustee or any Paying Agent
receives, at any time prior to the close of business on the Business Day immediately preceding the applicable Fundamental Change Repurchase Date, a letter or telegram, telex or facsimile transmission (receipt of which is confirmed and promptly
followed by a letter) setting forth (I) the name of such Holder, (II) a statement that such Holder is withdrawing its election to have Securities purchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase
Upon Fundamental Change, (III) the certificate number(s) of such 

  
 -24- 

 
Securities to be so withdrawn, if such Securities are in certificated form, (IV) the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an
integral multiple thereof and (V) the principal amount, if any, of the Securities of such Holder that remain subject to the Purchase Notice delivered by such Holder in accordance with this Section 3.13, which amount
must be $1,000 or an integral multiple thereof; 
 (xii) the Conversion Rate and any adjustments to the Conversion Rate that
will result from such Fundamental Change; 
 (xiii) that Securities with respect to which a Purchase Notice is given by a
Holder may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.13 or if there shall be a
Default in the payment of the consideration payable as herein provided upon a Repurchase Upon Fundamental Change; and 

(xiv) the CUSIP number or numbers, as the case may be, of the Securities. 

At the Company’s request, upon reasonable prior notice, the Trustee shall mail such Fundamental Change Notice in the Company’s name
and at the Company’s expense; provided, however, that the form and content of such Fundamental Change Notice shall be prepared by the Company. 

No failure of the Company to give a Fundamental Change Notice shall limit any Holder’s right to exercise a Fundamental Change Repurchase
Right. 
 (C) Subject to the provisions of this Section 3.13, the Company shall pay, or cause to be paid, the
Fundamental Change Repurchase Price with respect to each Security as to which the Fundamental Change Repurchase Right shall have been exercised to the Holder thereof as promptly as practicable, but in no event later than the later of the Fundamental
Change Repurchase Date and the time such Security (together with all necessary endorsements) is surrendered or transferred, by book-entry, is surrendered to the Paying Agent (except that, if the Fundamental Change Repurchase Date is after a Regular
Record Date and on or before the immediately following Interest Payment Date, then accrued and unpaid interest on such Securities to, but excluding, such Interest Payment Date will be paid, on such Interest Payment Date, to the Holder(s) of record
of such Securities at the close of business on such Regular Record Date without any requirement to surrender or transfer such Securities to the Paying Agent). 

(D) Prior to 10:00 A.M., New York City time on a Fundamental Change Repurchase Date, the Company shall deposit with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 10.03 of the Base Indenture) money, in funds immediately available on the Fundamental Change Repurchase Date, sufficient to pay the
consideration payable as herein provided for all of the Securities that are to be repurchased by the Company on such Fundamental Change Repurchase Date pursuant to the Repurchase Upon Fundamental Change. The Paying Agent shall return to the Company,
as soon as practicable, any money not required for that purpose. 

  
 -25- 

 (E) Once the Fundamental Change Notice and the Purchase Notice have been duly given in
accordance with this Section 3.13, the Securities to be repurchased pursuant to a Repurchase Upon Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable in accordance herewith, and, on
and after such date (unless there shall be a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change), except as otherwise herein provided, such Securities shall cease to bear interest, and all
rights of the Holders with respect to such Securities shall terminate, other than the right to receive, in accordance herewith, such consideration. 

(F) Securities with respect to which a Purchase Notice has been duly delivered in accordance with this Section 3.13
may be converted pursuant to Article X, if otherwise convertible in accordance with Article X, only if such Purchase Notice has been withdrawn in accordance with this Section 3.13 or if there shall be a
Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change. 
 (G) If any Security
shall not be paid upon surrender thereof for Repurchase Upon Fundamental Change, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the
principal amount of such Security, and such Security shall continue to be convertible pursuant to Article X. 
 (H) Any Security
which is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this Section 3.13 (with, if the Company or the Trustee so requires, 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 its attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the
Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not duly submitted
for Repurchase Upon Fundamental Change. 
 (I) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities to the contrary, there shall be no purchase of any Securities pursuant to this Section 3.13 if the principal amount of the Securities has been accelerated pursuant to Section 6.02 and such
acceleration shall not have been rescinded on or before the applicable Fundamental Change Repurchase Date. The Paying Agent will promptly return to the respective Holders thereof any Securities tendered to it for Repurchase Upon Fundamental Change
during the continuance of such an acceleration. 
 (J) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or
the Securities to the contrary, if the option granted to Holders to require the repurchase of the Securities upon the occurrence of a Fundamental Change is determined to constitute a tender offer, the Company shall comply with all applicable tender
offer rules under the Exchange Act, including Rule 13e-4 and Regulation 14E thereunder, and with all other applicable laws, and will file a Schedule TO or any other schedules required under the
Exchange Act or any other applicable laws.

and payable at the Maturity Date, upon any Option Purchase Date, Fundamental Change Repurchase Date, Redemption Date or redemption, or otherwise; 

  
 -28- 

 (ii) the Company fails to pay any interest on the Securities when due and

 (v) the Company fails to comply with Article V; 

(vi) the Company fails to perform or observe any of its other covenants or warranties in the Base Indenture or this
Supplemental Indenture or in the Securities for a period, and such failure continues for the period, and after the notice, specified below; 

(vii) the default by the Company or any of its Subsidiaries in the payment of principal or interest on any mortgage, agreement
or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any Indebtedness for money borrowed in excess of ten million dollars ($10,000,000) (or its foreign currency equivalent) in the aggregate of the
Company and/or any of its Subsidiaries, whether such Indebtedness now exists or shall hereafter be created; 
 (viii) the
Company or any of its Significant Subsidiaries or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company, pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar
law now or hereafter in effect or otherwise, either:

(B) consents to the entry of an order for relief against it in an involuntary case, 

(C) consents to the appointment of a Custodian of it or for all or substantially all of its property, or 

(D) makes a general assignment for the benefit of its creditors; or 

(ix) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against the Company or any of its Significant Subsidiaries or any group of Subsidiaries that in the aggregate
would constitute a 

  
 -29- 

 
Significant Subsidiary of the Company in an involuntary case or proceeding, or adjudicates the Company or any of its Significant Subsidiaries or any group of Subsidiaries that in the aggregate
would constitute a Significant Subsidiary of the Company insolvent or bankrupt, 
 (B) appoints a Custodian of the Company or

(C) orders the winding up or liquidation of the Company or any of its Significant Subsidiaries or any group of Subsidiaries
that in the aggregate would constitute a Significant Subsidiary of the Company, 
 and, in the case of each of the foregoing clauses (A),
(B) and (C) of this Section 6.01(ix), the order or decree remains unstayed and in effect for at least ninety (90) consecutive days. 

Each of the foregoing events shall constitute an Event of Default regardless of the reason for such event or whether it is voluntary or
involuntary or is 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. 

A Default under clause (vi) above is not an Event of Default until (I) the Trustee provides written notice to the
Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding provide written notice to the Company and the Trustee, of the Default and (II) the Default is not cured within ninety
(90) days after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” If the Holders of at least twenty five percent (25%) in aggregate
principal amount of the outstanding Securities request the Trustee to give such notice on their behalf, the Trustee shall do so. 
 
6.02 ACCELERATION. 
 Except as provided in Section 6.12, if an Event of Default
(excluding an Event of Default specified in Section 6.01(viii) or (ix) with respect to the Company (but including an Event of Default specified in Section 6.01(viii) or
(ix) solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company)) occurs and is continuing, the Trustee by written
notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding by written notice to the Company and the Trustee, may declare the Securities to be immediately due and
payable in full. Upon such declaration, the principal of, and any accrued and unpaid interest on, all Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(viii) or
(ix) with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(viii) or 

  
 -30- 

 (ix) solely with respect to a Significant Subsidiary of the Company or any group of Subsidiaries that
in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the principal of, and accrued and unpaid interest on, all the Securities shall ipso facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder. 
 The Holders of not less than a majority in principal amount of the outstanding
Securities may on behalf of the Holders of all the Securities waive any past default hereunder with respect to the Securities and its consequences, except a default (1) in the payment of the principal of or interest on any Security; or
(2) in respect of a covenant or provision hereof which cannot, under Article IX, be modified or amended without the consent of the Holder of each outstanding Security affected. Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto. 

6.03 OTHER REMEDIES. 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, if an Event of Default occurs
and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities or to enforce the performance of any provision of the Securities or this Indenture.

 The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative. 
 6.04 WAIVER OF PAST DEFAULTS. 

Subject to Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding
may, by notice to the Trustee, waive any past Default or Event of Default and its consequences, other than (A) a Default or Event of Default in the payment of the principal of, or interest on, any Security (whether upon maturity, Repurchase
Upon Fundamental Change, Redemption or Purchase at Holder’s Option or upon the due date for an installment of interest or otherwise), (B) a Default or Event of Default arising from a failure by the Company to convert any Securities in
accordance with this Indenture, (C) the Company’s failure to repurchase any Securities when required pursuant to the terms of this Indenture or (D) any Default or Event of Default in respect of any provision of this Indenture or the
Securities which, under Section 9.02, cannot be modified or amended without the consent of the Holder of each outstanding Security affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this Supplemental Indenture, the Base Indenture and the Securities, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.
This Section 6.04 shall be in lieu of Trust Indenture Act § 316(a)(1)(B), and, as permitted by the Trust Indenture Act, Trust Indenture Act § 316(a)(1)(B) is hereby expressly excluded from this Indenture. 

  
 -31- 

 6.05 CONTROL BY
MAJORITY. 
 The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the
time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, or that
the Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability, unless the Trustee is offered indemnity satisfactory to it in its sole discretion against all losses and expenses
caused by taking or not taking any action; provided, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. This Section 6.05 shall be in lieu of Trust
Indenture Act § 316(a)(1)(A), and, as permitted by the Trust Indenture Act, Trust Indenture Act § 316(a)(1)(A) is hereby expressly excluded from this Indenture. 

6.06 LIMITATION ON SUITS. 

Except as provided in Section 6.07, a Holder may not institute any proceeding under this Indenture, or for the
appointment of a receiver or a trustee, or for any other remedy under this Indenture unless: 
 (i) the Holder gives to the
Trustee written notice of a continuing Event of Default; 
 (ii) the Holders of at least twenty five percent (25%) in
aggregate principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy; 

(iii) such Holder or Holders offer and, if requested, provide to the Trustee indemnity reasonably satisfactory to the Trustee
against all related losses or expenses; 
 (iv) the Trustee does not comply with the request within sixty (60) days
after receipt of such notice, request and offer of indemnity; and 
 (v) during such sixty (60) day period, the Holders
of a majority in aggregate principal amount of the Securities then outstanding do not give the Trustee a direction inconsistent with the request. 

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 

6.07 RIGHTS OF HOLDERS TO RECEIVE
PAYMENT. 
 Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary,
the right of any Holder to receive payment of all amounts due with respect to the Securities, on or after the respective due dates as provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of the Holder. 

  
 -32- 

 Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities to the contrary, the right of any Holder to convert the Security in accordance with this Indenture, or to bring suit for the enforcement of such right, shall not be impaired or affected without the consent of the Holder. 

6.08 COLLECTION SUIT BY TRUSTEE. 

If an Event of Default specified in Section 6.01(viii) or (ix) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount due with respect to the Securities, including any unpaid and accrued interest. 

6.09 TRUSTEE MAY FILE PROOFS OF
CLAIM. 
 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee, any predecessor Trustee and the Holders allowed in any judicial proceedings relative to the Company or its creditors or properties. 

The Trustee may collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making
of such payments directly to the Holders, to pay the Trustee any amount due 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 6.07 of the Base Indenture. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding. 
 6.10 PRIORITIES. 

If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order: 

 

			
	First :	  	 to the Trustee for amounts due under Section 6.07 of the Base Indenture;

 

	Second :	  	 to Holders for all amounts due and unpaid on the Securities, without preference or priority of any kind, according to the amounts due and
payable on the Securities; and
  

	Third :	  	 to the Company.
  

  
 -33- 

 The Trustee, upon prior written notice to the Company, may fix a record date and payment
date for any payment by it to Holders pursuant to this Section 6.10. At least fifteen (15) days before each such record date, the Trustee shall mail to each Holder and the Company a written notice that states such
record date and payment date and the amount of such payment. 
 6.11 UNDERTAKING FOR
COSTS. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than ten percent (10%) in aggregate principal amount of the outstanding Securities. 

6.12 FAILURE TO COMPLY WITH
SECTION 4.02. 
 (A) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities to the contrary, if: 
 (i) an Event of Default occurs pursuant to Section 6.01(vi)
solely as a result of the Company failure to comply with Section 4.02 (such Event of Default, a “Reporting Event of Default”); and 

(ii) on or before the close of business on the date on which such Reporting Event of Default first occurs, the Company
notifies, in writing, each Holder and the Trustee and Paying Agent that it elects the provisions of this Section 6.12 to apply with respect to such Reporting Event of Default (such notice, the “Reporting Event of
Default Election Notice”), 
 then: 

(I) the sole remedy for such Reporting Event of Default during the period consisting of the three hundred and sixty five
(365) calendar days after the date such Reporting Event of Default occurs shall consist exclusively of the payment of additional interest (“Additional Interest”) on each Security, payable semiannually in arrears at a rate of
0.50% per annum on the principal amount of each Security; 
 (II) such Additional Interest shall accrue and be payable in the
same manner, and on the same dates, as the stated interest payable on the Securities; and 
 (III) the Securities shall be
subject to acceleration on account of such Reporting Event of Default as provided in Section 6.02 only if (A) such Reporting Event of Default is not cured by the calendar day following the first three hundred and sixty
five (365) calendar days after the date such Reporting Event of Default occurs or (B) the Company shall fail to pay when due, in accordance with this Indenture, any unpaid Additional Interest that has accrued on account of such Reporting
Event of Default. 

  
 -34- 

 (B) For avoidance of doubt, if the Company fails to provide, in accordance with
Section 6.12(A)(ii), the Reporting Event of Default Election Notice in respect of a Reporting Event of Default, then the Securities shall be subject to acceleration on account of such Reporting Event of Default as provided in
Section 6.02. 
 (C) Each references in this Supplemental Indenture, the Base Indenture or the Securities to
interest shall be deemed to include any and all Additional Interest to the extent provided for pursuant to this Section 6.12; provided, however, that Additional Interest shall accrue in addition to, and in no
event shall this Section 6.12(C) be deemed to reduce the Company’s obligation to pay, the stated interest and Contingent Interest, if any, on any Security. 

(D) For the avoidance of doubt, this Section 6.12 shall not affect the rights of Holders in the event of the
occurrence of any Event of Default other than a Reporting Event of Default. 
 VII. TRUSTEE 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, Section 6.05 of the Base Indenture shall
be deemed to be replaced in its entirety with the following paragraph: 
 Section 6.05 Notice of Default. If a Default or Event
of Default occurs and is continuing and is known to the Trustee, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within fifteen (15) days after it occurs; provided, however, that, except in
the case of a Default or Event of Default in payment of the principal of, or interest on, any Security when due, or in the payment of any conversion, redemption or repurchase obligation under this Indenture with respect to any Security, the Trustee
may withhold such notice if it believes doing so is in the interests of the Holders. 
 Notwithstanding anything in this Supplemental Indenture, the Base
Indenture or the Securities to the contrary, for all purposes with respect to the Securities, (A) the clause “and filed with the Commission and each stock exchange, if any, on which the Securities are listed” in the third (3rd)
paragraph of Section 6.06 of the Base Indenture shall be deemed to be deleted; and (B) the clause “Section 5.01(6) or (7)” in the penultimate paragraph of Section 6.07 of the Base Indenture shall be deemed to be
replaced with the clause “Section Section 6.01(viii) or (ix) of the Supplemental Indenture.” 

VIII. DISCHARGE OF SUPPLEMENTAL INDENTURE 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, Article IV of the Base Indenture shall not
apply to the Securities. 
 8.01 TERMINATION OF THE
OBLIGATIONS OF THE COMPANY. 
 This Supplemental Indenture shall cease to be
of further effect if (a) either (i) all outstanding Securities (other than Securities replaced pursuant to Section 3.06 of the Base 

  
 -35- 

 
Indenture) have been delivered to the Trustee for cancellation or (ii) all outstanding Securities have become due and payable at their scheduled maturity or upon Purchase at Holder’s
Option, Repurchase Upon Fundamental Change, Redemption or conversion, and in either case the Company irrevocably deposits, prior to the applicable due date, with the Trustee or the Paying Agent cash (and, if applicable in accordance with Article
X with respect to such Securities that have become due upon conversion, shares of Common Stock) sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 3.06 of the Base
Indenture) on the Maturity Date, Option Purchase Date, Fundamental Change Repurchase Date, Redemption Date or the date on which the consideration due upon conversion is, in accordance with Article X, due, as the case may be; (b) the
Company pays to the Trustee all other sums payable hereunder by the Company; (c) no Default or Event of Default with respect to the Securities shall exist on the date of such deposit; (d) such deposit will not result in a breach or
violation of, or constitute a Default or Event of Default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound; and (e) the Company has delivered to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for herein relating to the satisfaction and discharge of this Supplemental Indenture have been complied with; provided, however, that
Sections 2.02, 2.03, 2.04, 2.05, 2.09, 3.13, 4.01 and Articles VIII and X of this Supplemental Indenture, and Sections 3.06, 5.15, 6.07 and 10.03 of the Base Indenture, shall
survive any discharge of this Supplemental Indenture until such time as the Securities have been paid in full and there are no Securities outstanding. 
 
8.02 APPLICATION OF TRUST MONEY. 
 The Trustee shall hold in trust
all money deposited with it pursuant to Section 8.01 and shall apply such deposited money through the Paying Agent and in accordance with this Indenture to the payment of amounts due on the Securities. 

8.03 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any money in accordance with Sections 8.01 and 8.02 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture and the Securities shall be revived and
reinstated as though no deposit had occurred pursuant to Sections 8.01 and 8.02; provided, however, that if the Company has made any payment of amounts due with respect to any Securities because of the reinstatement of
its obligations, then the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. 

IX. AMENDMENTS 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, Article IX of the Base Indenture
(excluding Section 9.01(7) of the Base Indenture, which shall continue to apply to the Base Indenture) shall not apply to the Securities. 

  
 -36- 

 9.01 WITHOUT CONSENT OF

 The Company and the Trustee may amend or supplement this Indenture or the Securities without notice to or the
consent of any Holder:

Section 163(f)(2)(B) of the Internal Revenue Code; 
 (ix) to conform, as necessary, the Indenture and the form or terms
of the Securities to the description thereof contained under the caption “Description of the Debentures” in the prospectus supplement, dated October 21, 2009, of the Company in the form filed with the Commission on October 23,
2009 (File No. 333-160214); and 
 (x) to make other changes to the Indenture or
forms or terms of the Securities, provided that no such change, individually or in the aggregate with all other such changes, has or will have a material adverse effect on the interests of the Holders. 

9.02 WITH CONSENT OF HOLDERS. 

The Company may amend or supplement this Indenture or the Securities with the written consent of the Holders of at least a majority in
aggregate principal amount of the outstanding Securities (voting as a single class). Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the outstanding Securities may, by notice to the Trustee, waive
compliance by the Company with any provision of this Indenture or the Securities without notice to any other Holder. 

  
 -37- 

 Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the
Securities to the contrary, without the consent of each Holder of each outstanding Security affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not: 

(a) reduce the principal amount of or change the Maturity Date of any Security; 

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

(c) reduce any amount payable upon repurchase or redemption of any Security or change the time at which or circumstances under
which the Securities may or shall be repurchased or redeemed; 
 (d) impair the right of any Holder to institute suit for the
enforcement of any payment on, or with respect to, or of the conversion of, any Security; 
 (e) change the currency in which
any Security is payable; 
 (f) impair the right of any Holder to convert any Security in accordance with Article X or
reduce the number of shares of Common Stock or any other property receivable upon conversion in accordance with Article X; 

(g) modify the Redemption provisions of this Indenture in a manner adverse to the Holders; 

(h) reduce the quorum or voting requirements under this Indenture (including reducing the percentage in aggregate principal
amount of outstanding Securities whose holders must consent to a waiver of compliance with any provision of this Indenture or the Securities or a waiver of any Default or Event of Default); 

(i) change the Company’s obligation to maintain an office or agency in the places and for the purposes specified in
Section 2.03;

(l) reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a
modification to or amendment of any provision of this Indenture or the Securities. 

  
 -38- 

 Promptly after an amendment, supplement or waiver under Section 9.01
or this Section 9.02 becomes effective, the Company shall mail, or cause to be mailed, to Holders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to mail such notice shall
not in any way impair or affect the validity of such amendment, supplement or waiver. 
 It shall not be necessary for the consent of the
Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

9.03 COMPLIANCE WITH TRUST INDENTURE ACT.

 Every amendment, waiver or supplement to this Indenture or the Securities shall comply with the Trust Indenture Act as then in effect.

 9.04 REVOCATION AND EFFECT OF CONSENTS.

 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its
terms and thereafter binds every Holder. 
 After an amendment, supplement or waiver becomes effective with respect to the Securities, it
shall bind every Holder unless such amendment, supplement or waiver makes a change that requires, pursuant to Section 9.02, the consent of each Holder affected. In that case, the amendment, supplement or waiver shall bind
each Holder of a Security who has consented to it and, provided that notice of such amendment, supplement or waiver is reflected on a Security that evidences the same debt as the consenting Holder’s Security, every subsequent Holder of a
Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. 
 9.05
NOTATION ON OR EXCHANGE OF SECURITIES. 
 If
an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security as directed and prepared by the
Company about the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. 

9.06 TRUSTEE PROTECTED. 

The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article IX; provided,
however, that the Trustee need not sign any amendment, 

  
 -39- 

 
supplement or waiver authorized pursuant to this Article IX that adversely affects the Trustee’s rights, duties, liabilities or immunities. The Trustee shall be entitled to receive
and conclusively rely upon an Opinion of Counsel as to legal matters and an Officers’ Certificate as to factual matters that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture. 

X. CONVERSION 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, Article XIII shall not apply to the
Securities. 
 10.01 CONVERSION PRIVILEGE. 

(A) Subject to the provisions of Article III and this Article X, the Securities shall be convertible, in integral multiples
of $1,000 principal amount, into cash, shares of Common Stock or a combination of cash and shares of Common Stock in accordance with this Article X and as set forth below if any of the following conditions are satisfied: 

(i) Conversion Based on Satisfaction of Sale Price Condition. Prior to August 1, 2029, the Securities may be
surrendered for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after December 31, 2009 if the Last Reported Sale Price per share of the Common Stock for at least twenty (20) Trading Days during the
period of thirty (30) consecutive Trading Days ending on the last Trading Day of the preceding fiscal quarter is greater than or equal to one hundred and thirty percent (130%) of the Conversion Price on each such Trading Day. 

(ii) Conversion Upon Satisfaction of Trading Price Condition. Prior to August 1, 2029, the Securities may be
surrendered for conversion during the five (5) Business Day period after any ten (10) consecutive Trading Day period (such ten (10) 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 of Securities in accordance with the procedures set forth in the immediately following paragraph, for each Trading Day of such Measurement Period was less than
ninety five percent (95%) of the product of the Last Reported Sale Price per share of the Common Stock and the Conversion Rate on each such Trading Day (such condition, the “Trading Price Condition”). 

The Bid Solicitation Agent 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 unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Securities would be less than ninety five
percent (95%) of the product of the Last Reported Sale Price per share of the Common Stock and the applicable Conversion Rate. 

At such time, the Company shall instruct the Bid Solicitation Agent to determine the Trading Price of the Securities beginning
on the next Trading Day and 

  
 -40- 

 on each successive Trading Day until the Trading Price per $1,000 principal amount of Securities is greater
than or equal to ninety five percent (95%) of the product of the Last Reported Sale Price per share of the Common Stock and the applicable Conversion Rate. If the Trading Price Condition has been satisfied, the Company shall so notify Holders. If,
at any time after the Trading Price Condition has been satisfied, the Trading Price per $1,000 principal amount of Securities on a Trading Day is equal to or greater than ninety five percent (95%) of the product of the Last Reported Sale Price per
share of the Common Stock and the applicable Conversion Rate for such Trading Day, then the Company shall so notify Holders. 
 (iii)
Conversion Upon Certain Distributions. If, prior to August 1, 2029, the Company elects to: 
 (a) issue to all or
substantially all holders of the Common Stock rights entitling them to purchase, for a period expiring within sixty (60) days after the date of the distribution, shares of Common Stock at less than the average of the Last Reported Sale Prices
per share of the Common Stock for the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement of such issuance; or 

(b) distribute to all or substantially all holders of Common Stock assets or debt securities of the Company or rights to
purchase securities of the Company, 
 then, in each case, (I) the Company must notify Holders at least thirty (30) Scheduled
Trading Days prior to the Ex-Dividend Date for such distribution; and (II) the Securities may be surrendered for conversion at any time from the time the Company has given such notice until the earlier of
(x) 5:00 p.m., New York City time, on the Business Day immediately prior to the Ex-Dividend Date of such issuance or distribution and (y) the Company’s announcement that such issuance or
distribution will not take place. 
 (iv) Conversion Upon Occurrence of Certain Corporate Events. If, prior to the close of business
on the Business Day immediately preceding August 1, 2029: 
 (a) a Fundamental Change or a Make-Whole Fundamental Change
occurs; or 
 (b) the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or
substantially all of its assets, pursuant to which the Common Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other assets, 

then, in each case, (I) the Company shall notify Holders and the Trustee as promptly as practicable following (x) the date the
Company publicly announces such transaction, but in no event fewer than thirty (30) Scheduled Trading Days prior to the anticipated effective date of such transaction, and (y) the effective date of such transaction, but in any event,
within five (5) days after the effective date of such transaction; and (II) the 

  
 -41- 

 
Securities may be surrendered for conversion at any time from, and including, the thirtieth (30th) Scheduled Trading Day prior to the anticipated effective date of such transaction to, and
including, the thirty fifth (35th) Trading Day following such effective date or, if such transaction also constitutes a Fundamental Change, the Fundamental Change Repurchase Date for such Fundamental Change; provided, however, that if
the Company announces a transaction that causes the Securities to become convertible pursuant to this Section 10.01(A)(iv), but the transaction is not consummated, then on the date the Company announces that the transaction
will not occur, the Securities will cease to be convertible pursuant to this Section 10.01(A)(iv) on account of such transaction. 

(v) Conversion Based upon Notice of Redemption. If the Company calls any of the Securities for Redemption, then the
Securities may be surrendered for conversion at any time prior to the close of business on the second (2nd) Business Day immediately preceding the applicable Redemption Date. 

(vi) Conversion on or after August 1, 2029. The Securities may be surrendered for conversion at any
time from, and including, August 1, 2029 until the close of business of the second (2nd) Business Day immediately preceding the Maturity Date. 

(B) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, no Securities may be
surrendered for conversion after the close of business on the second (2nd) Business Day immediately preceding the Maturity Date. 

(C) The initial Conversion Rate shall be 25.5076 shares of Common Stock per $1,000 principal amount of Securities. The Conversion Rate
shall be subject to adjustment in accordance with Sections 10.05 through 10.13. 
 (D) A Holder may convert a portion of
the principal amount of a Security if such portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of
such Security. 
 10.02 CONVERSION PROCEDURE AND PAYMENT
UPON CONVERSION. 
 (A) To convert a Security, a Holder must satisfy the requirements of paragraph
9 of the Securities. If a Security is tendered for conversion in accordance with this Article X, then: 
 (i) the
Company shall deliver, through the Conversion Agent, the following to the Holder of such Security: 
 (a) if Physical
Settlement applies to such conversion, a number of shares of Common Stock equal to the product of the principal amount of such Security (expressed in thousands) and the Conversion Rate in effect on the Conversion Date of such conversion;
provided, however, that if such product is not a whole number, then the Company will pay a cash amount in lieu of issuing any fractional share, which cash amount shall be based on the VWAP per share of Common Stock on such Conversion Date;

  
 -42- 

 (b) if Cash Settlement applies to such conversion, a cash amount equal to
the product of the principal amount of such Security (expressed in thousands) and the Conversion Value applicable to such conversion; and 

(c) if Combination Settlement applies to such conversion, 

(I) a cash amount equal to the lower of (x) the Fixed Cash Amount applicable to such conversion and (y) the
Conversion Value applicable to such conversion; and 
 (II) a number of shares of Common Stock, if any, equal to the
sum, for each Trading Day in the Observation Period applicable to such conversion, of one-twentieth (1/20th) of a fraction (a) whose numerator is the excess, if any, of (1) the product
of the Conversion Rate in effect on such Trading Day and the VWAP per share of Common Stock on such Trading Day over (2) the Fixed Cash Amount applicable to such conversion and (b) whose denominator is such VWAP per share of
Common Stock; provided, however, that if such sum is not a whole number, then the Company will pay a cash amount in lieu of issuing any fractional share, which cash amount shall be based on the VWAP per share of Common Stock on the final
Trading Day of such Observation Period; 
 (ii) except as provided in Section 10.10 or
Section 10.13(G), the Conversion Consideration due upon such conversion shall be delivered by the Company as follows: (1) if Physical Settlement applies to such conversion, on the third (3rd) Trading Day following the
Conversion Date of such conversion (or, if earlier, the Maturity Date); and (2) in all other cases, on the third (3rd) Trading Day following the final Trading Day of the Observation Period applicable to such conversion; 

(iii) if Physical Settlement applies to such conversion, then the person in whose name the certificate representing the shares
of Common Stock constituting the Conversion Consideration due upon such conversion shall be treated as a stockholder of record of such shares as of the close of business on the Conversion Date of such conversion; 

(iv) if Combination Settlement applies to such conversion, then the person in whose name the certificate representing the
shares of Common Stock, if any, constituting the Conversion Consideration due upon such conversion shall be treated as a stockholder of record of such shares, without duplication, as follows: as of the close of business on each Trading Day (the
“relevant trading day”) during the Observation Period applicable to such conversion, such person shall be treated as a stockholder of record of a number of shares of Common Stock equal to the sum, for 

  
 -43- 

 
each Trading Day in such Observation Period occurring on or before such relevant trading day, of one-twentieth (1/20th) of a fraction (A) whose
numerator is the excess, if any, of (1) the product of the Conversion Rate in effect on such Trading Day and the VWAP per share of Common Stock on such Trading Day over (2) the Fixed Cash Amount applicable to such conversion and
(B) whose denominator is such VWAP per share of Common Stock (except that if such sum is not a whole number, then the fractional portion of such sum shall be ignored); and 

(v) on and after the Conversion Date for such conversion, all rights of the Holder(s) of such Security with respect to such
Security shall terminate, other than the right to receive the Conversion Consideration due upon such conversion in accordance with this Indenture. 

The Settlement Method applicable to each conversion of a Security shall be determined in accordance with
Section 10.02(B). 
 (B) If a Security is tendered for conversion in accordance with this Article X,
then, unless the Conversion Date of such conversion is on or after the Irrevocable Net Share Settlement Election Date, if any, the Company shall, no later than the second (2nd) Scheduled Trading Day immediately after such Conversion Date, provide
notice (the “Settlement Method Election Notice”) to the Holder of such Security and the Conversion Agent, through the Trustee, of whether the Conversion Consideration due upon such conversion shall be determined pursuant to
Section 10.02(A)(i)(a) (a “Physical Settlement”), Section 10.02(A)(i)(b) (a “Cash Settlement”) or Section 10.02(A)(i)(c) (a
“Combination Settlement”), which notice shall also state, in the case of Combination Settlement, the maximum amount of cash (excluding cash, if any, payable in lieu of any fractional share) due upon such conversion per $1,000
principal amount of such Security (such maximum cash amount per $1,000 principal amount, the “Fixed Cash Amount”); provided, however, that: 

(i) if the Company is required to provide a Settlement Method Election Notice for such conversion pursuant to this
Section 10.02(B) and fails to do so in accordance with this Section 10.02(B), then Combination Settlement, with an Fixed Cash Amount equal to one thousand dollars ($1,000), shall apply to such
conversion; 
 (ii) unless the Company shall have theretofore made an Irrevocable Net Share Settlement Election, the Company
may, prior to August 1, 2029, deliver a one-time notice (the “Free Convertibility Period Settlement Method Election Notice”) to Holders, the Trustee and the Conversion Agent, irrevocably
designating the Settlement Method that shall apply to each and every conversion of a Security whose Conversion Date occurs on or after August 1, 2029; if the Company so provides a Free Convertibility Period Settlement Method Election Notice,
then (I) the Company cannot thereafter rescind such notice; and (II) the Company need not, and may not, provide a Settlement Method Election Notice with respect to any conversion of a Security whose Conversion Date occurs on or after
August 1, 2029; 
 (iii) if, on August 1, 2029, the Company has not theretofore made an Irrevocable Net Share
Settlement Election and has not theretofore provided a Free 

  
 -44- 

 
Convertibility Period Settlement Method Election Notice in accordance with clause (ii) above, then (I) Combination Settlement, with a Fixed Cash Amount equal to one
thousand dollars ($1,000), shall apply to each and every conversion of any Security whose Conversion Date is on or after August 1, 2029; and (II) the Company need not, and may not, provide a Settlement Method Election Notice with respect
to any conversion of a Security whose Conversion Date occurs on or after August 1, 2029; and 
 (iv) the Company shall
have the right, in its sole discretion and without the consent of any Holder, to irrevocably elect (an “Irrevocable Net Share Settlement Election”), by notice to Holders, the Trustee and the Conversion Agent, promptly at any time
prior to August 1, 2029, that Combination Settlement, with an Fixed Cash Amount equal to one thousand dollars ($1,000), apply to each and every conversion of any Security whose Conversion Date is on or after the date (the “Irrevocable
Net Share Settlement Election Date”) the Company provides such notice, which election, once given, shall be irrevocable; provided, however, that the Company shall have the right to irrevocably renounce its right to make an
Irrevocable Net Share Settlement Election by notifying Holders, the Trustee and the Conversion Agent at any time prior to the earlier of the (A) August 1, 2029 and (B) the Company’s exercise of the Irrevocable Net Share
Settlement Election, in which case no Irrevocable Net Share Settlement Election is permitted to be made after such notice; if the Company has duly made an Irrevocable Net Share Settlement Election, then the Company need not, and may not, thereafter
provide a Settlement Method Election Notice in respect of any conversion of a Security or a Free Convertibility Period Settlement Method Election Notice. 

Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, if the Conversion Dates of two
(2) or more conversions of any Securities occur on the same Trading Day, then the same Settlement Method shall apply to each of such conversions. 

(C) Upon conversion of a Security in accordance with this Article X, the Holder of such Security shall not be entitled to receive,
on account of such conversion, any separate cash payment for accrued and unpaid interest, except as provided in the immediately following sentence. If a Holder surrenders a Security for conversion after 5:00 p.m., New York City time, on a Regular
Record Date and prior to the immediately following Interest Payment Date, then, notwithstanding such conversion, the interest payable with respect to such Security on such Interest Payment Date shall be paid on such Interest Payment Date to the
Holder of record of such Security at the close of business on such Regular Record Date; provided, however, that such Security, when surrendered for conversion, must be accompanied by payment to the Conversion Agent on behalf of the Company of
an amount equal to the interest payable on such Interest Payment Date on the portion of such Security to be so converted, except that no such payment is required if either (i) the Company shall have specified a Redemption Date or Fundamental
Change Repurchase Date that is after such Regular Record Date and on or prior to such Interest Payment Date; or (ii) the Conversion Date for such conversion is after the Regular Record Date that immediately precedes the Maturity Date;
provided further, however, that, if the Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of 

  
 -45- 

 
interest on such Security, then in no event shall the Holder of such Security who surrenders such Security for conversion be required to pay such defaulted interest or the interest that shall
have accrued on such defaulted interest (it being understood that nothing in this Section 10.02(C) shall affect the Company’s obligations under Section 4.01(B)). Notwithstanding anything in
this Supplemental Indenture, the Base Indenture or the Securities to the contrary, the final paragraph of Section 3.07 of the Base Indenture shall not apply to the Securities. 

(D) If a Holder converts more than one Security at the same time, the number of full shares of Common Stock issuable, if any, upon such
conversion shall be based on the total principal amount of all Securities converted. 
 (E) Upon surrender of a Security that is
converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered. 

(F) If the last day on which a Security may be converted is not a Business Day, then the Security may be surrendered to that Conversion
Agent on the next succeeding day that is a Business Day. 
 (G) The Company’s delivery of the Conversion Consideration due upon
any conversion of a Security will be deemed to satisfy in full the Company’s obligation to pay (A) the principal amount of such Security; and (B) accrued and unpaid interest to, but excluding, the Conversion Date of such conversion.
As a result, accrued and unpaid interest to, but excluding, such Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. 

10.03 TAXES ON CONVERSION. 

If a Holder converts its Security, the Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if
any, of shares of Common Stock upon such conversion, unless the tax is due because such Holder requests any such shares to be issued in a name other than such Holder’s name, in which case such holder shall pay such tax. Nothing herein shall
preclude any tax withholding required by law or regulation. 
 10.04 COMPANY TO
PROVIDE STOCK. 
 The Company shall at all times reserve out of its authorized but unissued Common Stock or
Common Stock held in its treasury enough shares of Common Stock to permit the conversion, in accordance herewith, of all of the Securities into shares of Common Stock. 

All shares of Common Stock which may be issued upon conversion of the Securities shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim. 

The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities
and shall list such shares on each national securities exchange or automated quotation system on which the Common Stock is listed. 

  
 -46- 

 10.05 ADJUSTMENT OF
CONVERSION RATE. 
 The Conversion Rate shall be subject to adjustment from time to time as follows: 

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

											
	CR1	 	=    CR0	 		 	x  	 	OS1	 	
	 	OS0	 	

 where, 

					
			
	CR0	 	=	 	the Conversion Rate in effect immediately prior to the Ex-Dividend Date of such dividend or distribution, or the effective date of such share split or combination, as applicable;
			
	CR1	 	=	 	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date or effective date, as applicable;
			
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to such Ex-Dividend Date or effective date, as applicable; and
			
	OS1	 	=	 	the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or share combination.

 Such adjustment shall become effective immediately after the opening of business on such
Ex-Dividend Date or the effective date, as applicable. 
 (b) If the Company
distributes to all or substantially all holders of Common Stock any rights or warrants entitling them, for a period expiring within sixty (60) calendar days after the declaration date of such distribution, to subscribe for or purchase shares of
Common Stock, at a price per share less than the Last Reported Sale Price per share of Common Stock on the Trading Day immediately preceding the declaration date of such distribution, then the Conversion Rate shall be adjusted based on the following
formula (provided that the Conversion Rate will be readjusted to the extent that such rights or warrants are not exercised prior to their expiration): 
  

											
	CR1  	 	=	 	CR0	 	x  	 	OS0 + X	 	
	 	OS0 + Y	 	

 where, 
  

					
	CR0	 	=	 	the Conversion Rate in effect immediately prior the Ex-Dividend Date for such distribution;

  
 -47- 

					
			
	CR1	 	=	 	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	 	=	 	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and
			
	Y	 	=	 	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale Prices per share of Common Stock over the ten
(10) consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

 To the extent such rights or warrants are not exercised prior to their expiration or termination, the Conversion Rate shall be
readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. If such
rights or warrants are not so issued, then the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the date fixed for the determination of shareholders entitled to receive such rights or warrants had
not been fixed. For the purposes of this Section 10.05(b) in determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the Last Reported Sale Price per
share of Common Stock on the Trading Day immediately preceding the declaration date of such distribution, and in determining the aggregate exercise price payable for such shares of Common Stock, there shall be taken into account any consideration
received by the Company for such rights or warrants and any amount payable upon exercise thereof, with the value of such consideration, if other than cash, as shall be determined in good faith by the Board of Directors. 

For the purposes of this Section 10.05(b) (and subject to Section 10.12), if (1) the Company
distributes any rights or warrants to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances); and (2) until the occurrence of a
specified event or events (each a “Trigger Event”), such rights or warrants are (a) are deemed to be transferred with such shares of Common Stock; (b) are not exercisable; and (3) are also issued in respect of future
issuances of Common Stock, then such rights or warrants shall be deemed not to have been distributed for purposes of this Section 10.05(b) (and no adjustment to the Conversion Rate pursuant to this
Section 10.05(b) shall be required on account of such distribution) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate
adjustment (if any is required) to the Conversion Rate shall be made pursuant to this Section 10.05(b). If any such rights or warrants, including any such existing 

  
 -48- 

 rights or warrants distributed prior to the date of this Supplemental Indenture, are subject to events, upon
the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of Indebtedness or other assets, then, for purposes of this Section 10.05(b), the date of the occurrence of each
such event shall be deemed to be the date of distribution and record date with respect to the distribution of new rights or warrants (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof).
In addition, in the event of any distribution (or deemed distribution) of rights 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 10.05(b) was made, (1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise
by any Holders thereof, the Conversion Rate shall be readjusted upon such final purchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a distribution to each holder of Common Stock of cash in an amount
equal to the redemption or purchase price received by such holder with respect to such rights or warrants, and (2) in the case of such rights 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. 
 (c) If the Company distributes
shares of its Capital Stock, evidences of the Company’s Indebtedness, other assets or property of the Company or rights or warrants to acquire the Company’s Capital Stock or other securities of the Company to all or substantially all
holders of Common Stock, excluding: 
 (1) dividends or distributions and rights or warrants as to which an adjustment is
required pursuant to Section 10.05(a), Section 10.05(b) or Section 10.05(d); and 

(2) a Spin-Off to which the provisions set forth below in this
Section 10.05(c) shall apply, 
 then the Conversion Rate will be adjusted 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;

  
 -49- 

					
	SP0	 	=	 	the average of the Last Reported Sale Prices per share of Common Stock over the ten (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 Capital Stock, evidences of Indebtedness, assets, property, rights or warrants distributed with respect to each outstanding share of Common Stock on
the Ex-Dividend Date for such distribution.

 Such adjustment shall become effective immediately after the opening of business on such
Ex-Dividend Date. If the Board of Directors determines the FMV by reference to the actual or when-issued trading market for any securities, then, in doing so, it must consider the prices in such market over
the same period used in computing SP0. Notwithstanding the foregoing, if FMV is equal to or greater than SP0, then, in lieu of the
foregoing adjustment, adequate provision shall be made so that each Holder shall receive on the date on which such Capital Stock, evidences of Indebtedness, assets, property, rights or warrants are distributed to holders of Common Stock, for each
$1,000 principal amount of Securities, the amount of such Capital Stock, evidences of Indebtedness, assets, property, rights or warrants a person who was a holder of record, on the record date for such distribution, of a number of shares of Common
Stock equal to the Conversion Rate then in effect would have been entitled to receive pursuant to such distribution. 
 With respect to an adjustment
pursuant to this Section 10.05(c) where there has been a payment of a dividend or other distribution on Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a
Subsidiary or other business unit of the Company (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 end of the Valuation Period applicable to such Spin-Off;
			
	CR1	 	=	 	the Conversion Rate in effect immediately after the end of such Valuation Period;
			
	FMV0	 	=	 	the average of the Last Reported Sale Prices per share of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined for purposes of the definition of Last
Reported Sale Price as if such Capital Stock or similar equity interest were Common Stock) over the first ten (10) consecutive Trading Day period after, and including, the effective date of such Spin-Off (the
“Valuation Period”); and

  
 -50- 

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

 The adjustment to the Conversion Rate pursuant to the immediately preceding formula shall occur on the last day of the
Valuation Period; provided that in respect of any conversion during such Valuation Period, references with respect to the ten (10) Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the
effective date of such Spin-Off and the Conversion Date of such conversion in determining the applicable Conversion Rate. 

(d) If any cash dividend or distribution is made to all or substantially all holders of Common Stock, the Conversion Rate will 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 per share of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	 	=	 	the amount in cash per share the Company distributes to holders of Common Stock.

 In the case of an adjustment pursuant to this Section 10.05(d), such adjustment shall become
effective immediately after the opening of business on such Ex-Dividend Date; provided, however, that if C is equal to or greater than SP0, then,
in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive on the date on which such cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal
amount of Securities, the amount of cash a person who was a holder of record, on the record date for such dividend or distribution, of a number of shares of Common Stock equal to the Conversion Rate then in effect would have been entitled to receive
pursuant to such dividend or distribution. 

  
 -51- 

 (e) If the Company or any of the Company’s Subsidiaries makes 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 Common Stock exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day
next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate will 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 tenth (10th) Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the tenth (10th) Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires;
			
	AC	 	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased in such tender or exchange offer;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for purchase or exchange in such offer); and
			
	SP1	 	=	  	the average of the Last Reported Sale Price per share of Common Stock over the ten (10) consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires.

 The adjustment to the Conversion Rate pursuant to this Section 10.05(e) shall occur on the tenth
(10th) Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the ten (10) Trading Days immediately following, and including, the
expiration date of such tender or exchange offer, references with respect to the ten (10) Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer
and the Conversion Date of such conversion in determining the applicable Conversion Rate. If the Company is, or one of the 

  
 -52- 

 
Company’s Subsidiaries is, obligated to purchase Common Stock pursuant to any such tender or exchange offer but is permanently prevented by applicable law from effecting any such purchase or
all such purchases are rescinded, then the Conversion Rate shall be readjusted to be the conversion rate that would be in effect if such tender or exchange offer had not been made. 

(f) Notwithstanding anything in this Section 10.05 to the Contrary, if any dividend or distribution subject to
Section 10.05(a), Section 10.05(c) or Section 10.05(d) is declared but not so paid or made, then the Conversion Rate shall be readjusted to the Conversion Rate that would then be
in effect if such dividend or distribution had not been declared. 
 (g) In addition to the foregoing adjustments in subsections (a),
(b), (c), (d) and (e) above, the Company may, subject to any applicable stock exchange listing requirements, increase the Conversion Rate by any amount for a period of at least twenty (20) Business Days
if the Board of Directors determines that such increase would be in the Company’s best interest. The Company shall 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, subject to any applicable stock exchange listing requirements. 

10.06 NO ADJUSTMENT. 

No adjustment in the Conversion Rate pursuant to this Article X shall be required unless the adjustment would require a change of at
least one percent (1%) in the Conversion Rate; provided, however, that the Company shall carry forward any adjustments that are less than one percent (1%) of the Conversion Rate and make such carried-forward adjustments on each
Conversion Date, and each Trading Day during any Observation Period relating to any Conversion Date. 
 No adjustment to the Conversion Rate
need be made pursuant to Section 10.05 for a transaction if Holders are to participate in the transaction without conversion on a basis and with notice that the Board of Directors determines in good faith to be fair and
appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. 
 Except as expressly
provided in this Article X, the Company shall 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 Common
Stock or such convertible or exchangeable securities; provided, however, that if the application of the Conversion Rate adjustment provisions of Section 10.05 would result in a decrease in the Conversion Rate or
reduce the Conversion Price below the par value per share of Common Stock, then no adjustment to the Conversion Rate shall be made (other than as a result of a share combination). 

Notwithstanding anything to the contrary in Section 10.05, the Conversion Rate shall not be adjusted pursuant to
Section 10.05 on account of a transaction if Holders participate, as a 

  
 -53- 

 
result of holding Securities, in such transaction without having to convert such Securities, as if each Holder held a number of shares of Common Stock equal to the product of the principal amount
of Securities held by such Holder (expressed in thousands) and the Conversion Rate then in effect. 
 10.07
OTHER ADJUSTMENTS. 
 In the event that, as a result of an adjustment made pursuant to this Article
X, the Holder of any Security thereafter surrendered for conversion shall become entitled to receive any shares of Capital Stock other than shares of Common Stock, thereafter the Conversion Rate of such other shares so receivable upon conversion
of any Security shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in this Article X. 

10.08 NOTICE OF ADJUSTMENT. 

Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Security
Registrar’s books a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the
correctness of such adjustment. 
 10.09 EQUITABLE ADJUSTMENTS. 

Notwithstanding the Conversion Rate adjustment provisions set forth in this Article X, if any Conversion Rate adjustment becomes
effective, or any Ex-Dividend Date relating to a required Conversion Rate adjustment occurs, during the period beginning on a Conversion Date with respect to a conversion and ending on the close of business on
the last Trading Day of the corresponding Observation Period, if any, the Board of Directors will make adjustments to the Conversion Rate or the amount of cash or number of shares of Common Stock issuable upon such conversion, as may be necessary or
appropriate to effect the intent of the such Conversion Rate adjustment provisions to avoid unjust or inequitable results, as determined in good faith by the Board of Directors, so long as such adjustments benefit the applicable Holder. Any
adjustment made pursuant to this Section 10.09 shall apply in lieu of the adjustment or other term that would otherwise be applicable. 

10.10 EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS,
MERGERS, BINDING SHARE EXCHANGES OR SALES ON CONVERSION PRIVILEGE. 

In the case of any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination or a change in par value), a consolidation, merger or combination involving the Company, a sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety, or any
statutory share exchange, in each case, as a result of which the Common Stock would be converted into, or exchanged for, or constitute solely the right to receive, stock, other securities or other property or assets (including cash or any
combination thereof), then, the Company shall, as a condition precedent to such transaction, execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee providing that, at the 

  
 -54- 

 
effective time of such transaction, the right to convert the Securities shall be changed into a right to convert each $1,000 principal amount of Securities into the kind and amount of shares of
stock, other securities or other property or assets (including cash or any combination thereof) (the “Reference Property”) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such
transaction would have received on account of such transaction, assuming such holder is entitled to participate in such transaction on the basis of holding such shares; provided, however, that, at and after the effective time of such
transaction, upon any conversion of a Security, (A) any portion of the Conversion Consideration due upon such conversion that would have been payable in cash pursuant to Section 10.02(A)(i) had such transaction not
occurred shall continue to be payable in cash, (B) any portion of the Conversion Consideration due upon such conversion that would have been payable in shares of Common Stock pursuant to Section 10.02(A)(i) had such
transaction not occurred shall instead be payable in such Reference Property and (C) the VWAP per share of Common Stock shall, for these purposes, be calculated based on the value of a unit of Reference Property that a holder of one
(1) share of Common Stock would have been entitled to receive in such transaction. 
 Except as provided in
Section 10.13(G), if the Reference Property in respect of such transaction consists solely of cash and the effective time of the such transaction occurs on or before the third Business Day after the last Trading Day in any
Observation Period applicable to the conversion of any Security (in the event Physical Settlement does not apply to such conversion) or on or before the third Business Day after the Conversion Date of such conversion (in the event Physical
Settlement applies to such conversion), then (i) the Conversion Consideration due upon such conversion shall consist of cash in an amount, per $1,000 principal amount of such Security, equal to the product of (A) the amount of cash paid
per share of Common Stock pursuant to such transaction and (B) the Conversion Rate on the Conversion Date for such conversion; and (ii) such consideration shall be paid no later than the third (3rd) Business Day after the later of such
Conversion Date and such effective date. 
 If such transaction causes the Common Stock to be converted into the right to receive more than
a single type of consideration (determined based in part upon any form of stockholder election), then the Reference Property into which the Securities shall be convertible shall be deemed to be the weighted average of the types and amounts of
consideration actually received by the holders of Common Stock, subject to the Company’s (or its successor’s) right, pursuant to Section 10.02(A)(i), to deliver, in lieu of Reference Property, cash or a
combination of cash and Reference Property. 
 The Company shall not become a party to any such transaction unless the terms of such
transaction are consistent with this Section 10.10. 
 The supplemental indenture referred to in the first
sentence of this Section 10.10 shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article X.
The foregoing, however, shall not in any way affect the right a Holder of a Security may otherwise have, pursuant to Section 10.12, to receive rights or warrants upon conversion of a Security. If the Reference Property
includes shares of stock or other securities and property of a Person other than the successor or purchasing Person, as the case may be, in such transaction, then such supplemental indenture shall also be executed by such other Person and shall
contain such 

  
 -55- 

 additional provisions to protect the interests of the Holders of the Securities as the Board of Directors in
good faith shall reasonably determine necessary by reason of the foregoing. The provisions of this Section 10.10 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers,
leases, conveyances or dispositions. 
 In the event the Company shall execute a supplemental indenture pursuant to this
Section 10.10, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities upon the
conversion of their Securities after such transaction and any adjustments to the Conversion Rate to be made on account of such Transaction. 
 
10.11 TRUSTEE’S DISCLAIMER. 
 The Trustee has no duty to determine when an
adjustment under this Article X should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the
Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.08 hereof. The Trustee makes no representation as to the validity or value of any securities or
assets issued or delivered upon conversion of Securities, and the Trustee shall not be responsible for the failure by the Company to comply with any provisions of this Article X. 

The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture
executed pursuant to Section 10.10, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is
obligated to file with the Trustee pursuant to Section 10.10 hereof. 
 10.12
RIGHTS DISTRIBUTIONS PURSUANT TO STOCKHOLDERS’ RIGHTS PLANS. 

Upon conversion of any Security or a portion thereof, the Company shall make provision for the Holder thereof, to the extent such Holder is to
receive any shares of Common Stock upon such conversion, to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable hereunder upon such conversion, the rights described in the Rights Agreement
or any other stockholders’ rights plan the Company may have in effect at such time, unless such rights have separated from the Common Stock at the time of such conversion, in which case the Conversion Rate shall be adjusted upon such separation
in accordance with Section 10.05(c). 
 10.13 INCREASED CONVERSION
RATE APPLICABLE TO CERTAIN SECURITIES SURRENDERED IN CONNECTION WITH MAKE-WHOLE
FUNDAMENTAL CHANGES. 
 (A) Notwithstanding anything in this Supplemental Indenture, the Base
Indenture or the Securities to the contrary, if a Make-Whole Fundamental Change occurs prior to November 1, 2017, then the Conversion Rate applicable to each Security to be converted, in accordance with this Article X, shall, if the
applicable Conversion Notice therefor is received by the Conversion Agent at any time from, and including, the Scheduled Trading Day following the effective date of such Make-Whole Fundamental Change to, and including, the thirty fifth (35th) 

  
 -56- 

 Trading Day immediately following the effective date of such Make-Whole Fundamental Change (or, if such
Make-Whole Fundamental Change constitutes a Fundamental Change, until the close of business on the Business Day immediately preceding the applicable Fundamental Change Repurchase Date), be increased to an amount equal to the Conversion Rate that
would, but for this Section 10.13, otherwise apply to such Security pursuant to this Article X, plus an amount equal to the Make-Whole Applicable Increase. 

For avoidance of doubt, the Conversion Consideration due upon a conversion of a Security to which this Section 10.13
applies shall be determined in accordance with Section 10.02(A)(i), based on the Conversion Rate as adjusted pursuant to this Section 10.13 (and any other applicable provisions of this
Indenture), and paid in accordance with Section 10.02(A)(ii). 
 (B) As used herein, “Make-Whole
Applicable Increase” shall mean, with respect to a Make-Whole Fundamental Change, the amount, set forth in the following table, which corresponds to the date such Make-Whole Fundamental Change occurs or becomes effective (the
“Effective Date”) and the Stock Price applicable to such Make-Whole Fundamental Change:

 provided, however, that: 

(i) if the actual Stock Price of such Make-Whole Fundamental Change is between two (2) prices listed in the table above
under the row titled “Stock Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two dates listed in the table above in the column immediately below the title “Effective Date,” then the
Make-Whole Applicable Increase for such Make-Whole Fundamental Change shall be determined by straight-line interpolation between the Make-Whole Applicable Increases set forth for the higher and lower Stock Price amounts and the earlier and later
Effective Dates, based on a three hundred and sixty five (365) or three hundred and sixty six (366) day year, as applicable; 

(ii) if the actual Stock Price of such Make-Whole Fundamental Change is greater than $125.00 per share (subject to adjustment
as provided in Section 10.13(B)(iii)), or if the actual Stock Price of such Make-Whole Fundamental Change is less than $29.04 per share (subject to adjustment as provided in Section 10.13(B)(iii)),
then the Make-Whole Applicable Increase shall be equal to zero (0); 
 (iii) if an event occurs that requires, pursuant to
this Article X (other than solely pursuant to this Section 10.13), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, (A) each price set 

  
 -57- 

 
forth in the table above under the column titled “Stock Price” shall be deemed to be adjusted so that such price, at and after such time, shall be equal to the product of (1) such
price as in effect immediately before such adjustment to such price and (2) a fraction whose numerator is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate to be
in effect, in accordance with this Article X, immediately after such adjustment to the Conversion Rate; and (B) each Make-Whole Applicable Increase amount set forth in the table above shall be adjusted in the same manner as the
Conversion Rate is adjusted pursuant to this Article X (excluding adjustments solely pursuant to this Section 10.13); and 

(iv) in no event shall the total number of shares of Common Stock issuable upon conversion of any Security exceed 34.4356
shares per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate; 
 (C) As used
herein, “Stock Price” shall have the following meaning with respect to a Make-Whole Fundamental Change: (a) if the holders of Common Stock receive only cash in such Make-Whole Fundamental Change, then the Stock Price with
respect to such Make-Whole Fundamental Change shall be the cash amount paid per share of Common Stock; (b) otherwise, the Stock Price with respect to such Make-Whole Fundamental Change shall be the average of the Last Reported Sale Prices per
share of Common Stock over the five (5) Trading Day period ending on the Trading Day preceding the Effective Date of such Make-Whole Fundamental Change. 

(D) At least thirty (30) calendar days before the anticipated effective date of each proposed Make-Whole Fundamental Change, the
Company shall mail to each Holder, in accordance with Section 1.06 of the Base Indenture, written notice of the anticipated effective date of such proposed Make-Whole Fundamental Change. Each such notice shall also state that, in connection
with such Make-Whole Fundamental Change, if consummated, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Securities entitled as provided herein to such increase (along with a description of how such increase
shall be calculated and the time periods during which Securities must be surrendered in order to be entitled to such increase). No later than the third (3rd) Business Day after the Effective Date of each Make-Whole Fundamental Change, the Company
shall mail to Holders, in accordance with Section 1.06 of the Base Indenture, written notice of such Effective Date and the Make-Whole Applicable Increase applicable to such Make-Whole Fundamental Change. 

(E) For avoidance of doubt, the provisions of this Section 10.13 shall not affect or diminish the
Company’s obligations, if any, pursuant to Article IV with respect to a Make-Whole Fundamental Change. 
 (F) Nothing in
this Section 10.13 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.05 in respect of a Make-Whole Fundamental Change. 

(G) If a Make-Whole Fundamental Change occurs and the consideration for the Common Stock in such Make-Whole Fundamental Change is
comprised entirely of cash, then, notwithstanding anything to the contrary in the second paragraph of Section 10.10, (i) the 

  
 -58- 

 
Conversion Consideration due in respect of each conversion of a Security following the Effective Date of such Make-Whole Fundamental Change shall be deemed to be a cash amount equal to the
applicable Conversion Rate (including any adjustment pursuant to this Article X) multiplied by the Stock Price applicable to such Make-Whole Fundamental Change; and (ii) the Conversion Consideration shall be determined and paid, to each
Holder that converts a Security, in cash on the third (3rd) Business Day following the Conversion Date of such conversion. 

10.14 EXCHANGE IN LIEU OF CONVERSION. 

(A) Notwithstanding anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, if a Holder surrenders
any Security for conversion, the Company may, but is not obligated to, direct the Conversion Agent to surrender, on or prior to the second (2nd) Business Day following the Conversion Date of such conversion, such Security to a financial institution
designated by the Company (which may not be an Affiliate of the Company; provided that, for purposes of this Section 10.14, an “Affiliate” shall include any Person with direct or indirect ownership of ten
percent (10%) or more of the equity of the Company or the power to directly or indirectly vote more than ten percent (10%) of the securities having ordinary voting power for the election of directors of the Company) (a “Financial
Institution”) for exchange in lieu of conversion. In order to accept any Securities surrendered for conversion, such designated institution must agree to deliver, in exchange for such Securities, the Conversion Consideration due upon such
conversion in accordance with this Indenture. By the close of business on the second (2nd) Business Day immediately following such Conversion Date, the Company shall notify such Holder, the Trustee and the Conversion Agent that the Company has
directed the designated financial institution to make an exchange in lieu of such conversion, and such financial institution shall be required to notify the Conversion Agent, no later than the close of business on the second (2nd) Business Day
immediately following such Conversion Date, of the Settlement Method applicable to such conversion, which Settlement Method must comply with the terms of this Indenture. 

(B) In order to accept such Security surrendered for conversion, the Financial Institution must agree to deliver, in exchange for such
Security, the Conversion Consideration due upon such conversion as prescribed by Section 10.02(A)(i) (it being understood that such Financial Institution shall be permitted to provide a Settlement Method Election Notice
with respect to such conversion in accordance with Section 10.02(B), if the Company is permitted to provide such a Settlement Method Election Notice pursuant to Section 10.02(B)). 

(C) If such Financial Institution so accepts any such Security to be converted, then it shall deliver the Conversion Consideration due
upon such conversion to the Conversion Agent, and the Conversion Agent shall deliver such Conversion Consideration to the applicable Holder, in each case within the time frames prescribed by Section 10.02(A)(ii). Each
Security so exchanged by such designated institution shall remain outstanding. 
 (D) If such Financial Institution agrees to accept
such Security for exchange but does not timely deliver the related consideration, or if such Financial Institution does not accept such Security for exchange, then the Company shall deliver, as soon as practicable, the applicable Conversion
Consideration as if the Company had not made an exchange election. 

  
 -59- 

 (E) The Company shall not provide to the Financial Institution, directly or indirectly,
any of such Conversion Consideration to be delivered by the Financial Institution in exchange for such Security. 
 (F) In no event
shall the Company’s designation of a Financial Institution pursuant to this Section 10.14 require such Financial Institution to accept any Securities for exchange. The Company shall not be obligated to pay any
consideration to, or otherwise enter into any agreement or arrangement with, a Financial Institution for or with respect to such designation pursuant to this Section 10.14. 

XI. TAX TREATMENT

 (2) to treat the Securities as debt instruments that

(4) to treat the delivery of Common Stock or cash (including cash delivered in lieu of a fractional share) to a Holder of a
Security upon conversion of such Security, as a contingent payment (in an amount equal to the sum of the fair market value of such Common Stock and any cash received (as determined in good faith by the Board of Directors of the Company)) under
Treasury Regulation section 1.1275-4(b). 
 11.02 COMPARABLE
YIELD AND PROJECTED PAYMENT SCHEDULE. 
 (a)
Solely for purposes of applying Treasury Regulation section 1.1275-4 to the Securities: 

(1) for U.S. federal income tax purposes, the Company shall accrue interest with respect to outstanding Securities as original
issue discount according to the “noncontingent bond method,” as set forth in Treasury Regulation section 1.1275-4(b), using a comparable yield of 8.25%, compounded semiannually, and the projected
payment schedule as determined by the Company; and 

  
 -60- 

 (2) the Company shall file with the Trustee promptly following the end of
each calendar year (A) a written notice specifying the amount of original issue discount for U.S. federal income tax purposes accrued on outstanding Securities as of the end of such year and (B) such other specific information relating to
such original issue discount that the Company determines to be relevant under the Internal Revenue Code of 1986, as amended from time to time, including the amount of any adjustment made under the noncontingent bond method to account for the amount
of any difference between the amount of an actual payment and the amount of a projected payment. 
 Holders that wish to obtain the
projected payment schedule may do so by submitting a written request to the Company (to the attention of Investor Relations) at 520 Madison Avenue, New York, New York 10022.

 [REVERSE OF SECURITY] 

JEFFERIES GROUP, INC. 

3.875% Convertible Senior Debenture due 2029 

1. Interest. Jefferies Group, Inc., a Delaware corporation (the “Company”), promises to pay interest on the
principal amount of this Security at the rate per annum shown above. The Company will pay interest, payable semi-annually in arrears, on May 1 and November 1 of each year, with the first payment to be made on May 1, 2010.
Interest on the Securities will accrue on the principal amount from, and including, the most recent date to which interest has been paid or provided for or, if no interest has been paid, from, and including, October 26, 2009, in each case to,
but excluding, the next Interest Payment Date or Maturity Date, as the case may be. Interest will be computed on the basis of a 360-day year composed of twelve 30-day
months. 
 In addition, if the Contingent Interest Trading Price of a Security for each of the five (5) Trading Days (the
“Contingent Interest Measurement Period”) ending on the third (3rd) Trading Day immediately preceding the first day of any six (6) month period (each a “Contingent Interest Period”) from and including an
Interest Payment Date to but excluding the next Interest Payment Date, commencing with the six (6) month period beginning on November 1, 2017, is equal to or greater than one thousand two hundred dollars ($1,200.00) per one thousand
dollars ($1,000) principal amount of the Securities, then the Company shall pay contingent interest (“Contingent Interest”) to the Holders. 

The amount of Contingent Interest payable per $1,000 principal amount of Securities in respect of any Contingent Interest Period, if
applicable, shall be equal to 0.375%, per annum, of the average Contingent Interest Trading Price per $1,000 principal amount of the Securities during the applicable Contingent Interest Measurement Period. Contingent Interest shall accrue from, and
including, the first day of the applicable Contingent Interest Period through, but excluding, the Interest Payment Date at the end of such Contingent Interest Period, and Contingent Interest shall be payable to Holders in the same manner as regular
cash interest. Regular cash interest shall continue to accrue at the per annum rate of 3.875% on the principal amount of the Securities whether or not Contingent Interest is paid. 

The Company shall instruct the Bid Solicitation Agent to determine the daily Contingent Interest Trading Prices of the Securities during each
Contingent Interest Measurement Period during which any Securities are outstanding. Upon determining that the Securities shall begin to accrue Contingent Interest during a Contingent Interest Period, the Company shall, on or before the start of such
Contingent Interest Period, provide notice to the Trustee setting forth the amount of Contingent Interest per $1,000 principal amount of Securities and disseminate a press release through a public medium that is customary for such press releases.

 The “Contingent Interest Trading Price” of a Security on any Trading Day means the average of the secondary market bid
quotations per Security obtained by the Bid Solicitation Agent for five million dollars ($5,000,000) principal amount of the Securities at approximately 3:30 p.m., New York City time, on such Trading Day from three (3) independent nationally

  
 A-3 

 
recognized securities dealers selected by the Company, which may include one or more of the Underwriters, provided, however, that if at least three (3) such bids cannot reasonably be
obtained by the Bid Solicitation Agent, but two (2) such bids can reasonably be obtained by the Bid Solicitation Agent, then the average of such two (2) bids shall be used, and if only one (1) such bid can be obtained by the Bid
Solicitation Agent, then that one (1) bid shall be used; provided further that if the Bid Solicitation Agent cannot reasonably obtain at least one (1) bid for five million dollars ($5,000,000) principal amount of the Securities from
a nationally recognized securities dealer or if, in the Company’s reasonable judgment, the bid quotations are not indicative of the secondary market value of the Securities, then the Contingent Interest Trading Price of a Security shall be
determined by the Board of Directors based on a good faith estimate of the fair value of the Securities. 
 Contingent Interest, if any,
shall accrue and be payable in the same manner, and on the same dates, as the stated interest payable on the Securities. 
 Notwithstanding
anything in this Supplemental Indenture, the Base Indenture or the Securities to the contrary, the Company may unilaterally increase the amount of Contingent Interest the Company may pay or pay interest or other amounts the Company is not obligated
to pay; provided, however, that the Company shall have no obligation to do so. 
 2. Maturity. The Securities will mature
on November 1, 2029. 
 3. Method of Payment. Except as provided in the Indenture (as defined below), the Company will pay
interest on the Securities to the persons who are Holders of record of Securities at the close of business on the Regular Record Date set forth on the face of this Security next preceding the applicable Interest Payment Date. Except as provided in
the Indenture, Holders must surrender Securities to a Paying Agent to collect the principal amount, Redemption Price, Option Purchase Price, or Fundamental Change Repurchase Price of the Securities, as the case may be. The Company will pay, in money
of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which amounts shall be paid (A) in the case this Security is in global form, by
wire transfer of immediately available funds to the account designated by the Depositary for the Securities or its nominee; (B) in the case of a Security that is held, other than global form, by a Holder of more than five million dollars
($5,000,000) in aggregate principal amount of Securities, either by check mailed to such Holder or, upon application by such Holder to the Security Registrar not later than the relevant Regular Record Date (or, in the case of a payment of principal,
not later than fifteen (15) Business Days prior to the due date thereof), by wire transfer in immediately available funds to such Holder’s account within the United States, which application shall remain in effect until such Holder
notifies, in writing, the Security Registrar to the contrary; and (C) in the case of a Security that is held, other than global form, by a Holder of five million dollars ($5,000,000) or less in aggregate principal amount of Securities, by
mailing a check to the address of such Holder set forth in the Security Registrar’s books. 
 4. Paying Agent, Security
Registrar, Conversion Agent. Initially, The Bank of New York Mellon (the “Trustee”) will act as Paying Agent, Security Registrar, Bid Solicitation Agent and Conversion Agent. The Company may change any Paying Agent, Security
Registrar, Bid Solicitation Agent or Conversion Agent without notice.

 5. Indenture. The Company issued the Securities under an indenture dated as of
October 26, 2009 (the “Base Indenture”) between the Company and the Trustee, as amended, supplemented or otherwise modified by the First Supplemental Indenture (the “Supplemental Indenture”), dated as of
October 26, 2009, between the Company and the Trustee (the Base Indenture, as amended, supplemented or otherwise modified by the Supplemental Indenture, the “Indenture”). The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of such terms. The Securities
are general unsecured senior obligations of the Company limited to three hundred and forty five million dollars ($345,000,000), except as otherwise provided in the Indenture (except for Securities issued in substitution for destroyed, mutilated,
lost or stolen Securities). Terms used herein without definition and which are defined in the Indenture have the meanings assigned to them in the Indenture. 

6. Provisional and Optional Redemption. 

The Company shall have the right, at the Company’s option, at any time, and from time to time, on a Redemption Date on or after
November 1, 2012 and before November 1, 2017, to redeem (a “Provisional Redemption”) all or any part of the Securities at a price, payable in cash, equal to the Redemption Price, if the Last Reported Sale Price per share
of Common Stock for twenty (20) or more Trading Days in a period of thirty (30) consecutive Trading Days ending on the Trading Day prior to the date the Company provides the notice of Provisional Redemption pursuant to
Section 3.06 of the Supplemental Indenture exceeds one hundred and thirty percent (130%) of the Conversion Price in effect on the applicable Trading Day. 

The Company shall have the right, at the Company’s option, at any time, and from time to time, on a Redemption Date on or after
November 1, 2017, to redeem (an “Optional Redemption”) all or any part of the Securities at a price payable in cash equal to the Redemption Price. 

7. Purchase by the Company at the Option of the Holder. Subject to the terms and conditions of the Indenture, the Company shall
become obligated to purchase, at the option of each Holder, the Securities held by such Holder on November 1, 2017, November 1, 2019 and November 1, 2024 (each, an “Option Purchase Date”) at the Option Purchase Price,
payable in cash, upon the due delivery, in accordance with the Indenture, of a Purchase Notice containing the information set forth in the Indenture, and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the
Indenture. 
 8. Repurchase at Option of Holder Upon a Fundamental Change. Subject to the terms and conditions of the Indenture,
in the event of a Fundamental Change, each Holder of the Securities shall have the right, at the Holder’s option, to require the Company, upon the Holder’s satisfaction of certain conditions set forth in the Supplemental Indenture, to
repurchase such Holder’s Securities on a date selected by the Company (the “Fundamental Change Repurchase Date”), which Fundamental Change Repurchase Date shall be no later than thirty five (35) days, nor earlier than
twenty (20) Business Days, after the date the Fundamental Change Notice is mailed in accordance with Section 3.13(B) of the Supplemental Indenture, at a price, payable in cash, equal to the Fundamental Change
Repurchase Price for such Securities. 

  
 A-5 

 9. Conversion. 

The Securities are convertible during the times, and upon the conditions, set forth in Article X of the Supplemental Indenture.

 To convert a Security, a Holder must (1) complete and manually sign the Conversion Notice on the back of such Security, or a
facsimile of such Conversion Notice; (2) deliver such Conversion Notice, which is irrevocable, and such Security to the Conversion Agent; (3) if required, furnish appropriate endorsements and transfer documents; (4) if required, pay
all transfer or similar taxes; and (5) if required pursuant to Section 10.02(C) of the Supplemental Indenture, pay funds equal to interest payable on such Security the next Interest Payment Date; provided,
however, that if such Security is represented by a Global Security, then, in lieu of clauses (1), (2) and (3), such Holder must comply with the Depositary’s procedures for the same. 

A Holder may convert a portion of a Security if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount.

 Each conversion of a Security will be settled pursuant to Physical Settlement, Cash Settlement or Combination Settlement in accordance
with the Indenture. 
 The initial Conversion Rate is 25.5076 shares of Common Stock per $1,000 principal amount of Securities, subject to
adjustment in the event of certain circumstances as specified in the Indenture. The Company will pay cash in lieu of any fractional share. If a Holder surrenders a Security for conversion after 5:00 p.m., New York City time, on a Regular Record Date
and prior to the immediately following Interest Payment Date, then, notwithstanding such conversion, the interest payable with respect to such Security on such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record
of such Security at the close of business on such Regular Record Date; provided, however, that such Security, when surrendered for conversion, must be accompanied by payment to the Conversion Agent on behalf of the Company of an amount equal
to the interest payable on such Interest Payment Date on the portion of such Security to be so converted, except that no such payment is required if either (i) the Company shall have specified a Redemption Date or Fundamental Change Repurchase
Date that is after such Regular Record Date and on or prior to such Interest Payment Date; or (ii) the Conversion Date for such conversion is after the Regular Record Date that immediately precedes the Maturity Date; provided further,
however, that, if the Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of interest on such Security, then in no event shall the Holder of such Security who surrenders such Security for
conversion be required to pay such defaulted interest or the interest that shall have accrued on such defaulted interest (it being understood that nothing in this paragraph shall affect the Company’s obligations under
Section 4.01(B) of the Supplemental Indenture). 
 10. Tax Agreements. Each Holder and beneficial
holder of a Security by its purchase of a Security is deemed to make certain agreements relating to the tax treatment of such Security. See Article XI of the Indenture. 

  
 A-6 

 11. Denominations, Transfer, Exchange. The Securities are in registered form,
without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Security Registrar may
require a Holder, among other things, to furnish appropriate endorsements and transfer documents. 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 similar governmental charge that may be imposed in connection with certain transfers or exchanges. The Company or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security for which a Purchase
Notice has been delivered, and not withdrawn, in accordance with the Indenture, except the unrepurchased portion of Securities being repurchased in part. The Company is not required to effect any transfer or exchange of Securities in certain
situations, as set forth in the Indenture. 
 12. Persons Deemed Owners. The registered Holder of a Security may be treated as
the owner of such Security for all purposes. 
 13. Defaults and Remedies. The Securities may become immediately due and payable
in full after the occurrence of an Event of Default if certain conditions are satisfied, as provided in Article VI of the Supplemental Indenture. 

14. Trustee Dealings with the Company. The Trustee under the Indenture, or any banking institution serving as successor Trustee
thereunder, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for, the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. 

15. No Recourse Against Others. No past, present or future director, officer, employee or stockholder, as such, of the Company
shall have any liability for any obligations of the Company under the Securities or the Indenture or for 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 the issue of the Securities. 

16. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent in accordance with the Indenture. 
 17. Abbreviations. Customary abbreviations may be used in the name of
a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

 THE COMPANY WILL FURNISH TO ANY HOLDER UPON WRITTEN REQUEST AND WITHOUT CHARGE A COPY OF THE BASE INDENTURE OR THE SUPPLEMENTAL
INDENTURE. REQUESTS MAY BE MADE TO:

forms or terms of the Securities, provided that no such change, individually or in the aggregate with all other such changes, has or will have a material adverse effect on the interests of the Holders. 

Terms used herein without definition that are defined in the Original Indenture or the First Supplemental Indenture shall have the respective

of, the Company under this Indenture with the same effect as if such Surviving Person had been named as the Company herein. When a Surviving Person duly assumes all of the obligations of the Company pursuant hereto and pursuant to the Securities,
the predecessor shall be relieved of the performance and observance of all obligations and covenants of this Indenture and the Securities, including but not limited to the obligation to make payment of the principal of and interest, if any, on all
