 RECITALS 

WHEREAS, the Company and Executive entered into the Agreement; 
 WHEREAS, the Company and Executive desire to amend the Agreement to be as set forth herein. 
 NOW,
THEREFORE, in compliance with Section 16 of the Agreement and in consideration of the mutual promises and covenants set forth herein and in the Agreement and Statement of Work, the Client and the Company hereby agree as follows: 
 Section 4.1 of the Agreement is hereby amended to read in its entirety: 
 “Salary. As compensation for the proper and satisfactory performance of all duties to be performed by Executive hereunder, Company shall pay to Executive a base salary of $285,000.00 per year,
less applicable withholdings (the “Base Salary”). Until the receipt of gross proceeds from equity or debt or other financing obtained by Company of at least Five Million Dollars ($5,000,000) in the aggregate after July 7, 2009, eighty
percent (80%) of the Base Salary or $9,500 for each applicable semi-monthly pay period, less applicable withholdings, shall be paid in accordance with the Company’s regularly established payroll practice. The remaining $2,375 for each
applicable semi-monthly pay period, less applicable withholdings and applicable withholdings, shall be paid in the event of (i) a receipt of gross proceeds from equity or debt or other financing obtained by Company of at least Five Million
Dollars ($5,000,000) in the aggregate after July 7, 2009, (ii) a termination of Executive’s employment under the Agreement by the

 
Company without Cause or (iii) a termination of Executive’s employment under the Agreement by Executive for Good Reason but in no event later than March 15 of the year following
the year of each such applicable semi-monthly pay period. After the receipt of gross proceeds from equity or debt or other financing obtained by Company of at least Five Million Dollars ($5,000,000) in the aggregate after July 7, 2009, the Base
Salary shall be paid in accordance with the Company’s regularly established payroll practice. In the event Executive’s employment under this Agreement is terminated by either party, for any reason, Executive will be entitled to receive
such amount of his salary earned as provided in this Section through the date of such termination.” 
 Section 4.2 of the Agreement is
hereby amended to read in its entirety: 
 Incentive Compensation. 
  

	 	(a)	Discretionary Incentive Compensation. Executive may be granted incentive compensation in the Company’s discretion. If Company, in its sole and absolute
discretion, grants Executive incentive compensation, the terms, amount and payment of such incentive compensation will be determined solely by Company. Such incentive compensation may be payable in either cash or stock of the Company or any
combination thereof at the election of the Company, in its sole discretion, and pursuant to terms and conditions established by the Board of Directors of the Company. 

  

	 	(b)	Debt or Equity Financing. In the event the Company receives aggregate gross proceeds not less than $5,000,000 from debt or equity financings after July 7,
2009 and prior to December 31, 2010 (excluding proceeds from funds managed by Vision Capital Advisors, LLC), Executive shall receive incentive compensation set forth in Section 4.2 (c) below for raising such additional debt or equity
financing provided that Executive is employed with the Company at the time of such receipt of gross proceeds. 

  

	 	(c)	 Calculation. In the event the Company receives aggregate gross proceeds not less than $5,000,000 from equity financings after July 7, 2009
and prior to December 31, 2010 (excluding proceeds from funds managed by Vision Capital Advisors, LLC), such compensation will be initially based on a percentage of Executive’s Base Salary listed in Table 1 below taking into account the
amount raised, the pre-money valuation and the date by which such amount is raised. In the event the Company receives aggregate gross proceeds not less than $5,000,000 from straight debt financings after July 7, 2009 and prior to
December 31, 2010 (excluding proceeds from funds managed by Vision Capital Advisors, LLC), such compensation will be initially based on a percentage of Executive’s Base Salary listed in the $42.5M pre-money valuation row in Table 1 below
and the date by which such amount is raised.

	 	 
In the event the Company receives aggregate gross proceeds not less than $5,000,000 from convertible debt financings after July 7, 2009 and prior to December 31, 2010 (excluding
proceeds from funds managed by Vision Capital Advisors, LLC), such compensation will be initially based on a percentage of Executive’s Base Salary listed in Table 1 below taking into account the amount raised, the pre-money valuation and the
date by which such amount is raised assuming conversion of such convertible debt. In the event such converted pre-money valuation is unknown, the Board of Directors of the Company will determine the appropriate percentage of Executive’s Base
Salary upon which the incentive compensation, if any, will be initially based. Any incentive compensation payable by the Company pursuant to this Section 4.2(c) will be paid, as determined by the Board of Directors of the Company, in its sole
discretion, in either (i) cash or (ii) a combination of cash and up to the percentage of such incentive compensation in Incentive Stock Options issued pursuant to the Company’s 2008 Stock Incentive Plan in lieu of cash as set forth in
Table 1 below with the value of such options determined by the Black Scholes valuation method used by the Company to value stock options in its audited financial statements. Any incentive compensation payable pursuant to this Section 4.2(c) in
cash will be paid to Executive as soon as administratively practicable following the applicable date set forth in Table 1 below but in no event later than March 15, 2011. Any incentive compensation payable pursuant to this Section 4.2(c)
in stock options will be granted to Executive at the first meeting of the Compensation Committee of the Board of Directors following the applicable date set forth in Table 1 below but in no event later than March 15, 2011.

	 	(d)	 Sale Bonus. In the event of the liquidation, dissolution or winding up of the affairs of the Company (including in connection with a permitted
sale of all or substantially all of the Company’s assets or in connection with a liquidation, dissolution or winding up of the affairs of the Company described in Section 4 of the Certificate of Designation of the Relative Rights and
Preferences of the Series B-1 Convertible

	 	 
Participating Preferred Stock of the Company), whether voluntary or involuntary, the Company shall pay Executive 2.5% of the Series B-1 Liquidation Preference Amount (as defined in such
Certificate of Designation) after an amount equal to the original purchase price of the Company’s Series B-1 Preferred Stock then outstanding is paid to the holders of such Series B-1 Preferred Stock (the “Sale Bonus”); provided that
Executive is employed with the Company sixty (60) days prior to such liquidation, dissolution or winding up. The Sale Bonus will be paid in cash to Executive as soon as administratively practicable following the date of such liquidation,
dissolution or winding up of the affairs of the Company but in no event later than March 15 of the year following the year in which such liquidation, dissolution or winding up occurs or the year in which Executive employment is terminated,
whichever is earlier.” 

 Section 4.3 of the Agreement is hereby amended to read in its entirety: 
 Stock Options and Warrants. Executive may be granted stock options from time to time in the discretion of the Company subject to the terms
and conditions of a Company approved stock option plan and pursuant to the stock option agreement under which such options are granted. The Company shall grant Executive stock options pursuant to the Stock Option Agreement attached hereto as Exhibit
A. The Company shall grant Executive warrants to purchase shares of the Company’s Common Stock pursuant to the warrant agreement set forth in Exhibit B attached hereto. Prior to the completion of any future financings, the Board will convene
for purposes of increasing the number of stock options through additional issuances to the target percentage of 4.0% of the outstanding as converted securities of the Company (including common stock plus convertible preferred stock of the Company on
an as converted basis), post such new financing and increasing the amount of warrants through additional issuances to the target percentage of 5% of the issued and outstanding warrants of the Company, post such new financing.” 
 Section 7.2 of the Agreement is hereby amended to read in its entirety: 
 “Termination Without Cause By Company/Severance. Company may terminate Executive’s employment under this Agreement without Cause at any time. In the event of such termination, Executive will
receive the Standard Entitlements plus the following Severance Pay: (a) twelve (12) months of Executive’s Base Salary then in effect on the date of termination; provided, however, that for purposes of this Section 7.2 (and any
other section in this Agreement that refers to this Section 7.2), “Base Salary” will mean the greater of the Executive’s base salary then in effect or $285,000, and twelve (12) months of Executive’s health care benefits
then in effect on the date of termination provided the cost to the Company of such health care benefits does not exceed the cost in effect on the date of termination (the “Severance Pay”) and (b) the vesting of any stock options held
by Executive at the time of such termination will accelerate as to the number of shares that otherwise would have vested and been exercisable as of the date that is

 
twenty-four (24) months from the date of termination. The Severance Pay will be payable upon termination. Executive’s receipt of the Severance Benefits will be contingent upon:
(x) Executive’s compliance with all surviving provisions of this Agreement as specified in subparagraph 15.7 below; (y) Executive’s execution of a full general release in a form provided by the Company, releasing all claims,
known or unknown, that Executive may have against Company arising out of or any way related to Executive’s employment or termination of employment with Company; and (z) Executive’s agreement to act as a consultant for Company for up
to a maximum of sixty (60) calendar days immediately following the date of termination, without additional compensation, if requested to do so by Company. The Severance Benefits described herein will be paid or will commence, as applicable, as
soon as administratively practicable but within ten (10) calendar days following the Executive’s “separation from service” within the meaning of Section 409A of the Code. 
 Section 7.4(c) of the Agreement is hereby amended to read in its entirety: 
 “(c) 280G. If, due to the benefits provided under subparagraph 7.4(a) above and/or any other benefits, Executive is subject to any excise tax due to characterization of any amounts payable under
subparagraph 7.4(a) and/or any other benefits as excess parachute payments pursuant to Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), the Company, in its sole discretion, may elect to reduce the amounts
payable under subparagraph 7.4(a) and/or any other benefits in order to avoid any “excess parachute payment” under Section 280G(b)(1) of the Code; provided, however, that any such reduction shall be made in the order that least
diminishes the economic value of such payments and benefits.” 
 The Company and Executive hereby acknowledge and consent to the foregoing
amendments to the Agreement as set forth herein. 
 Except as amended herein, all other terms and provisions of the Agreement shall remain in
full force and effect. 
 This Amendment shall be effective upon its execution by the Company and Executive. 
 This Amendment may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. In
the event that any signature is delivered by facsimile or electronic transmission, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect
as if such facsimile or electronic signature were the original thereof. 
 IN WITNESS WHEREOF, the parties have duly executed this Amendment as
of the date first written above.

 INDENTURE dated as of March 19, 2010 between KNIGHT CAPITAL GROUP, INC., a Delaware
corporation, as issuer (the “Company”, as more fully set forth in Section 1.01) and DEUTSCHE BANK TRUST COMPANY AMERICAS, as trustee (the “Trustee”, as more fully set forth in Section 1.01). 
 W I T N E S S E T H: 
 WHEREAS, for its lawful corporate purposes, the Company has duly authorized the issuance of its 3.50% Cash Convertible Senior Subordinated Notes due 2015 (the “Notes”), initially in an aggregate principal amount not to

outstanding Notes represented thereby may from time to time be increased or reduced to reflect repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in
the amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with this Indenture. Payment of
principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining
Holders eligible to receive payment is provided for herein. 
 Section 2.03. Date and Denomination of Notes; Payments of
Interest and Defaulted Amounts. (a) The Notes shall be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the date of its authentication and shall
bear interest from the date specified on the face of the form of Note attached as Exhibit A hereto. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months (other than Additional Interest
payable pursuant to Section 4.06(d), which will accrue immediately upon the requirement to pay such Additional Interest as described in Section 4.06(d)). 
 (b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Interest Record Date with respect to any Interest Payment Date shall be
entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office or agency of the Company maintained by the Company for such purposes, which shall initially be the Corporate Trust Office. The Company
shall pay interest (i) on any Physical Notes (A) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to
Holders having an aggregate principal amount of more than $5,000,000, either by check mailed to the Holders of these Notes at their address as it appears in the Note Register or upon application by a Holder to the Note Registrar not later than the
relevant Interest Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary
or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee. 
  

 13 

 (c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant
payment date by virtue of its having been such Holder but shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date to, but excluding,
the date on which such Defaulted Amounts shall have been paid by the Company, at its election in each case, as provided in clause (i) or (ii) below: 
 (i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their
respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of
the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same
time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the
proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted
Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the
Trustee of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be mailed, first-class postage prepaid,
to each Holder at its address as it appears in the Note Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so mailed, such
Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause
(ii) of this Section 2.03(c). 
 (ii) The Company may make payment of any Defaulted Amounts in any
other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated
quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Section 2.04. Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by
the manual or facsimile signature of any of its Officers. 
  

 14 

 At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and
deliver such Notes, without any further action by the Company hereunder. 
 Only such Notes as shall bear thereon a certificate
of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee as provided by
Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence
that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture. 
 In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed
of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such
persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such Person was not such an Officer. 
 Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause
to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable
period of time. The Trustee is hereby appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-Note Registrars in accordance with
Section 4.02. 
 Upon surrender for registration of transfer of any Note to the Note Registrar or any co-Note Registrar,
and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of
any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 
 Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the
Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing
registration numbers not contemporaneously outstanding. 
  

 15 

 All Notes presented or surrendered for registration of transfer or for exchange, repurchase
or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly
executed, by the Holder thereof or its attorney-in-fact duly authorized in writing. 
 No service charge shall be charged to the
Holder for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a
result of the name of the Holder of the new Notes issued upon such exchange being different from the name of the Holder of the old Notes surrendered for such exchange. 
 None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 14. 
 All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of
the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. 
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall be represented by one or more Notes in global form without interest
coupons (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note,
shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. 
 (c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c)
(collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or
otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c), the term
“transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
 Until the date (the “Resale Restriction Termination Date”) that is the later of (1) one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 under the
Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof) shall bear a
legend in substantially the following form (unless such Notes have been transferred pursuant to a

  

 16 

 
registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee): 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER
(THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
 (1) REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE
MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND 
 (2) AGREES FOR THE BENEFIT OF THE COMPANY THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE
YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

 (A) TO KNIGHT CAPITAL GROUP, INC. (THE “COMPANY”) OR ANY SUBSIDIARY THEREOF, OR 

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR 
 (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 
 (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
 PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH
(2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN
COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
  

 17 

 No transfer of any Note prior to the Resale Restriction Termination Date will be registered
by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked. 
 Any Note (or
security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions
of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c). The Company shall promptly notify the Trustee upon the
occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Notes has been declared effective under the Securities Act. 
 Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may
not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a
beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(c). 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to
act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for the
Depositary. 
 If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to
continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within
90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of the Notes requests that its Notes be issued as Physical Notes, the Company will execute, and the Trustee, upon receipt of an
Officers’ Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and deliver Physical Notes to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount
equal to the principal amount of such beneficial owner’s interest in such Global Note. 
 Physical Notes issued in exchange
for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 
  

 18 

 At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest
in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal
amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such
Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
 None of
the Company, the Trustee and any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests of a Global Note or maintaining,
supervising or reviewing any records relating to such beneficial interests. 
 (d) The Company shall not permit any of its
“affiliates” (as defined in Rule 144 under the Securities Act) to resell any of the Notes that upon resale would constitute “restricted securities” under Rule 144 that have been reacquired by any of them. 
 Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen,
the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
 The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security
or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be
converted in accordance with Article 13 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of
the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the

  

 19 

 
Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or
expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof. 
 Every substitute Note issued pursuant to the provisions
of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall
be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and
owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender. 
 Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an
authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the
form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the
Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company will execute and deliver to the Trustee or such
authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to
Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense
and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

 Section 2.08. Cancellation of Notes Paid, Converted, Etc. All Notes surrendered for the purpose of payment,
repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to
the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary
procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the
indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. 
  

 20 

 Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee
in writing of any change in the “CUSIP” numbers. 
 Any Notes that are, when issued, Restricted Securities shall be
issued with a restricted CUSIP number. Until such time as the Company notifies the Trustee to remove the restrictive legend specified in Section 2.05(c) from the Notes, the restricted CUSIP shall be the CUSIP number for the Notes. At such time
as the Company notifies the Trustee to remove the restrictive legend specified in Section 2.05(c) from the Notes, such legend shall for all purposes of this Indenture and the Notes (including this Section 2.09) be deemed removed from any
Global Note and an unrestricted CUSIP number for the Notes shall be deemed to be the CUSIP number for the Notes. 
 Section
2.10. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, issue additional Notes hereunder with the same terms (except for the date on which interest begins to accrue in
respect of such additional Notes) and with the same CUSIP number (or different CUSIP numbers) as the Notes initially issued hereunder in an unlimited aggregate principal amount; provided that such additional Notes must be part of the same
issue as the Notes initially issued hereunder for U.S. federal income tax purposes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order and an Officers’ Certificate and Opinion of
Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. Such additional Notes shall be considered outstanding (as defined in
Section 1.01) for all purposes under this Indenture. The Company may also from time to time repurchase the Notes in open market purchases or negotiated transactions without giving prior notice to Holders. Any Notes repurchased by the Company
shall be cancelled pursuant to Section 2.08 (and, if not cancelled upon repurchase, shall be deemed to be cancelled) and be deemed to be no longer outstanding under this Indenture. 
 ARTICLE 3 
 SATISFACTION AND
DISCHARGE 
 Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company
contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes
theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06 and (y) Notes for whose payment money has theretofore been
deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or

  

 21 

 
discharged from such trust, as provided in Section 4.04(d)) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to
Holders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash sufficient to pay all of the outstanding Notes and all other sums due and
payable under this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive. 
 ARTICLE 4 
 PARTICULAR COVENANTS OF THE COMPANY 
 Section 4.01. Payment of Principal and Interest. The Company covenants and agrees that it will cause to be paid the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on,
each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. 
 Section 4.02.
Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or
repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of Manhattan, The City of New York (if other than the Corporate Trust Office). 
 The Company may also from time to time designate as co-Note Registrars one or more other offices or agencies where the Notes may be
presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The
terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable. 
 The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office and the office or agency of the Trustee in the
Borough of Manhattan, The City of New York, each shall be considered as one such office or agency of the Company for each of the aforesaid purposes. 
  

 22 

 Section 4.03. Appointments to Fill Vacancies in Trustee’s Office. The Company,
whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder. 
 Section 4.04. Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company
will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04: 
 (i) that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental Change
Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes; 
 (ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and
unpaid interest on, the Notes when the same shall be due and payable; and 
 (iii) that at any time during the
continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust. 
 The Company shall, on or before each due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such
principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action;
provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date. 
 (b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid
interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so
becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued
and unpaid interest on, the Notes when the same shall become due and payable. 
 (c) Anything in this Section 4.04 to the
contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the
Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the
Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts. 
  

 23 

 (d) Any money deposited with the Trustee or any Paying Agent, or then held by the Company,
in trust for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the Fundamental
Change Repurchase Price, if applicable) or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officers’ Certificate, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid or delivered to the Company. 
 Section 4.05. Existence. Subject to Article 11, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 4.06. Rule 144A Information Requirement and Annual Reports. (a) At any time the Company is not subject to Sections 13 or
15(d) of the Exchange Act, the Company shall, so long as any of the Notes shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and shall,
upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Notes the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes pursuant to
Rule 144A under the Securities Act. The Company shall take such further action as any Holder or beneficial owner of such Notes may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such
Notes in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time. 
 (b) The Company
shall file with the Trustee within 15 days after the same are required to be filed with the Commission, copies of any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange
Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that the Company files with the Commission via the Commission’s EDGAR system (or any successor thereto) shall be deemed to be
filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system. 
 (c) Delivery of the reports and documents described in subsection (b) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). 
  

 24 

 (d) If, at any time during the six-month period beginning on, and including, the date which
is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable
(after giving effect to all applicable grace periods thereunder (provided that in addition to any such applicable grace periods thereunder, the Company shall have 14 days, in the aggregate, to cure all such missed filings) and other than
reports on Form 8-K), the Company shall pay Additional Interest on the Notes in the form of a one-time payment of 0.50% on the principal amount of the Notes then outstanding. The Additional Interest payable pursuant to this subsection (d) shall
be payable on the Interest Payment Date immediately succeeding the late filing. As used in this Section 4.06(d), documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of
the Exchange Act does not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of the Exchange Act. 
 (e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed or the Notes are not otherwise freely tradable by Holders other than the
Company’s Affiliates (without restrictions pursuant to the terms of this Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the Notes at a rate equal
to 0.50% per annum of the principal amount of Notes outstanding until the Notes are freely tradable by Holders other than the Company’s Affiliates (without restrictions pursuant to the terms of this Indenture or the Notes). Any Additional
Interest payable pursuant to this subsection (e) shall be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes, and will be in addition to any Additional Interest that may accrue
at the Company’s election as the sole remedy relating to the failure to comply with its reporting obligations pursuant to Section 6.03. When the Notes become freely tradable as described above, accrued and unpaid Additional Interest
payable pursuant to this subsection (e) to, but excluding, the date on which the Notes become freely tradable shall be paid in cash on the next Interest Payment Date. 
 (f) If Additional Interest is payable by the Company pursuant to subsection (d) or (e) of this Section 4.06, the Company
shall deliver to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible
Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it,
the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment. 
 Section
4.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may
affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder,
delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  

 25 

 Section 4.08. Compliance Certificate; Statements as to Defaults. The Company shall
deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2010) an Officers’ Certificate stating whether or not the signers thereof have knowledge of any
failure by the Company during the previous fiscal year to comply with all conditions and covenants then required to be performed under this Indenture and, if so, specifying each such failure and the nature thereof. 
 In addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the Company becomes aware
of the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or is proposing to take in respect thereof.

 Section 4.09. Further Instruments and Acts. Upon reasonable request of the Trustee, the Company will execute and
deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
 ARTICLE 5 
 LISTS OF HOLDERS
AND REPORTS BY THE COMPANY AND THE TRUSTEE 
 Section 5.01. Lists of Holders. The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee, semi-annually, not more than 15 days after each Interest Record Date
in each year beginning with September 1, 2010, and at such other times as the Trustee may request in writing, within 30 days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to
enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the Holders as of a date not more than 15 days (or such other date as the Trustee may
reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished so long as the Trustee is acting as Note Registrar. 
 Section 5.02. Preservation and Disclosure of Lists. The Trustee shall preserve, in as current a form as is reasonably practicable,
all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in Section 5.01 or maintained by the Trustee in its capacity as Note Registrar, if so acting. The Trustee may destroy any
list furnished to it as provided in Section 5.01 upon receipt of a new list so furnished. 
 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 Section 6.01. Events of Default. The following events shall be “Events of Default” with respect to the Notes:

 (a) default in any payment of interest on any Note when due and payable, and the default continues for a period of 30 days
(whether or not such payment is prevented by the provisions of Article 16); 
  

 26 

 (b) default in the payment of principal of any Note when due and payable on the Maturity
Date, upon required repurchase in connection with a Fundamental Change or upon acceleration (whether or not such payment is prevented by the provisions of Article 16); 
 (c) failure by the Company to comply with its obligation to convert the Notes into cash in accordance with this Indenture upon exercise of a Holder’s conversion right and such failure continues for a
period of five days or more (whether or not the payment due upon conversion of such Notes into cash is prevented by the provisions of Article 16); 
 (d) failure by the Company to issue a Fundamental Change Company Notice in accordance with Section 14.01(c) for a period of five Business Days after such notice becomes due or notice of a specified

 (e)
failure by the Company to comply with its obligations under Article 11; 
 (f) failure by the Company for 60 days after written
notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding has been received by the Company to comply with any of its other agreements contained in the Notes or this Indenture; 
 (g) default by the Company or any Significant Subsidiary with respect to any mortgage, agreement or other instrument under which there is
outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed in excess of $40 million in the aggregate of the Company and/or any such Significant Subsidiary, whether such indebtedness now exists or shall hereafter be
created, (i) resulting in the acceleration of such indebtedness or (ii) constituting a failure to pay the principal or interest of any such indebtedness when due and payable at its stated maturity; provided that no Event of Default
shall be deemed to occur if (x) in the case of clause (i), such acceleration ceases or shall have been cured, waived, rescinded or annulled or such indebtedness for money borrowed shall have been paid or otherwise discharged, in each case,
within 30 days after the date of such acceleration, or (y) in the case of clause (ii), such defaulted payment shall have been made or the obligation to make such defaulted payment shall have been waived or extended, in each case, within 30 days
of such failure to pay; 
 (h) a final judgment for the payment of $40 million or more (excluding any bonded amounts or amounts
covered by insurance) rendered against the Company or any Significant Subsidiary, which judgment is not discharged or stayed within 60 days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or
(ii) the date on which all rights to appeal have been extinguished; 
 (i) the Company or any Significant Subsidiary shall
commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any Federal or State bankruptcy, insolvency or other similar law now
or hereafter in effect or seeking the appointment of a trustee, receiver,

  

 27 

 
liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due;
or 
 (j) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking
liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any Federal or State bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a
trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a
period of 30 consecutive days. 
 Section 6.02. Acceleration; Rescission and Annulment. In case one or more Events of
Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order,
rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company, and subject to
Section 6.03), unless the unpaid principal amount of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in
accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may, and the Trustee at the request of such Holders shall, declare 100% of the unpaid principal amount of, and accrued and unpaid
interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary
notwithstanding. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company occurs and is continuing, 100% of the principal of, and accrued and unpaid interest on, all Notes shall be automatically
and immediately due and payable. 
 This provision, however, is subject to the conditions that if, at any time after the
principal amount of the Notes shall have been so declared due and payable, (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Defaults under this
Indenture, other than the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and interest on, the Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant
to Section 6.09, then the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default (except for any Default or Event of
Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes or (ii) a failure to pay the cash due upon conversion of the
Notes) with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. 
  

 28 

 Section 6.03. Additional Interest. Notwithstanding anything in this Indenture or in
the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall after the occurrence of such an
Event of Default consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to: 
 (a)
0.25% per annum of the principal amount of the Notes outstanding for each day during the 60-day period beginning on, and including, the occurrence of such an Event of Default during which such Event of Default is continuing; and 
 (b) 0.50% per annum of the principal amount of the Notes outstanding for each day during the 120-day period beginning on, and
including, the 61st day following, and including, the occurrence of such an Event of Default during which such Event of Default is continuing. 
 Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). If the
Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest on the Notes. On the 181st day after such Event of Default (if the Event of Default relating to the Company’s failure
to comply with its obligations as set forth in Section 4.06(b) is not cured or waived prior to such 181st day), the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay
Additional Interest following an Event of Default in accordance with this Section 6.03, the Notes shall be subject to acceleration as provided in Section 6.02. Nothing contained in this Section 6.03 shall affect the rights of Holders
of Notes in the event of the occurrence of any other Event of Default. 
 In order to elect to pay Additional Interest as the
sole remedy during the first 180 days after the occurrence of any Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b), the Company must notify all Holders of the Notes, the
Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02. 
 Section 6.04. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of
Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any
overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to
pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final
decree and may enforce the same against the Company and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated. 
  

 29 

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

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the
possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery
of judgment shall, after provision for the payment of the reasonable compensation, out-of-pocket expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. 
  

 30 

 In any proceedings brought by the Trustee (and in any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such
proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall
have been discontinued or abandoned because of waiver or rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and
the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though
no such proceeding had been instituted. 
 Section 6.05. Application of Monies Collected by Trustee. Any monies collected
by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid: 
 First, to the payment of all amounts due the
Trustee under Section 7.06; 
 Second, in case the principal of the outstanding Notes shall not have become due and be
unpaid, to the payment of interest on, and cash due upon conversion of, the Notes in default in the chronological order of the date the payments of such interest and cash due upon conversion became due, as the case may be, with interest (to the
extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto; 
 Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid, to the payment of
the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and the cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and,
to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid
upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over
principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due
upon conversion) and accrued and unpaid interest; and 
 Fourth, to the payment of the remainder, if any, to the Company.

 Section 6.06. Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if
applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment of the cash due upon conversion, no Holder of any Note

  

 31 

 
shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this
Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless: 
 (a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided; 
 (b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder; 
 (c) such Holders shall have offered to the
Trustee such security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby; 
 (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 
 (e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the
Holders of a majority in principal amount of the Notes outstanding within such 60-day period pursuant to Section 6.09, 
 it being
understood and intended, and being expressly covenanted by the Holder of every Note with every other Holder and the Trustee, that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for
the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either
at law or in equity. 
 Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any
Holder to receive payment of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest on, and (z) the cash due upon conversion of, such Note, on or after the respective
due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such
Holder. 
 Section 6.07. Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy
or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by
this Indenture or by law. 
  

 32 

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

Section 6.09. Direction of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority in aggregate
principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any
trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal
liability. Prior to taking any action under this Indenture, the Trustee will be entitled to indemnification as provided for in Section 7.01 hereof. 
 The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, determined in accordance with Section 8.04 and including, without limitation, consents obtained in
connection with a repurchase of, or tender offer or exchange offer for, Notes, may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of
accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.01, (ii) a failure by the Company to pay
the cash due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such
waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent
thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be
not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
 Section 6.10. Notice of Defaults. The Trustee shall, within 90 days after the occurrence and continuance of a Default of which a Responsible Officer has knowledge, mail to all Holders, as the names
and addresses of such Holders appear upon the Note Register, notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a
Default in the payment of the

  

 33 

 
principal (including the Fundamental Change Repurchase Price, if applicable) of, the cash due upon conversion or, or accrued and unpaid interest on, any of the Notes, the Trustee shall be
protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. 
 Section 6.11. Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any
Holder for the enforcement of the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, the cash due upon conversion of, or accrued and unpaid interest, if any, on any Note on or after the due date expressed

 ARTICLE 7 
 CONCERNING THE TRUSTEE

 Section 7.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such
Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own
grossly negligent failure to act or its own willful misconduct, except that: 
 (a) prior to the occurrence of an Event of
Default and after the curing or waiving of all Events of Default that may have occurred: 
 (i) the duties and
obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no
implied covenants or obligations shall be read into this Indenture against the Trustee; and 
  

 34 

 (ii) in the absence of bad faith and willful misconduct on the part of the
Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture;
but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein); 
 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in
ascertaining the pertinent facts; 
 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken
by it in good faith in accordance with the direction of the Holders of not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 8.04 relating to the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 
 (d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of
this Section; 
 (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to
receive or any other matters relating to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to the Notes; 
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to
the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred, unless such Responsible Officer of the Trustee had actual knowledge of such event; 
 (g) in the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest
bearing trust account, and in no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon or for losses incurred as a result of the liquidation of any such investment prior to its maturity date or
the failure of the party directing such investments prior to its maturity date or the failure of the party directing such investment to provide timely written investment direction, and the Trustee shall have no obligation to invest or reinvest any
amounts held hereunder in the absence of such written investment direction from the Company; and 
  

 35 

 (h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent,
Conversion Agent, Bid Solicitation Agent or transfer agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 7 shall also be afforded to such Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid
Solicitation Agent or transfer agent. 
 None of the provisions contained in this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. 
 Section 7.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 7.01: 
 (a) the Trustee may conclusively rely and shall be fully protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, Note, coupon
or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company; 
 (c) the Trustee may consult with counsel and require an Opinion of Counsel and any advice of such counsel or Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
 (d) the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered
to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that may be incurred therein or thereby; 
 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation;

  

 36 

 (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents, custodians, nominees or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent, custodian, nominee or attorney appointed by it with due care
hereunder; and 
 (g) the permissive rights of the Trustee enumerated herein shall not be construed as duties. 
 In no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action other than any such loss or damage caused by the Trustee’s willful misconduct or gross negligence. The Trustee shall
not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or
Event of Default shall have been given to the Trustee by the Company or by any Holder of the Notes. 
 Section 7.03. No
Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any
Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
 Section 7.04.
Trustee, Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent, Bid Solicitation Agent (if other than the Company) or Note Registrar, in its individual or
any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee, Paying Agent, Conversion Agent, Bid Solicitation Agent (if other than the Company) or Note Registrar. 
 Section 7.05. Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied as herein provided, be held
in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as may be agreed from time to time by the Company and the Trustee. 
 Section 7.06.
Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company, and the Company will pay or reimburse the Trustee upon its request for all
reasonable out-of-pocket expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity thereunder (including the reasonable

  

 37 

 
compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as shall have been
caused by its gross negligence, willful misconduct or bad faith. The Company also covenants to indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents and
any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers, directors, agents or
employees, or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending
themselves against any claim of liability in connection with the exercise or performance of any of its powers or duties hereunder, except those attributable to its negligence, willful misconduct or bad faith. The obligations of the Company under
this Section 7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or property
held or collected by the Trustee, except, subject to the effect of Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s right to receive payment of any amounts due under this
Section 7.06 shall not be subordinate to any other liability or indebtedness of the Company. The obligation of the Company under this Section 7.06 shall survive the satisfaction and discharge of this Indenture and the earlier resignation
or removal or the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The indemnification provided in this Section 7.06 shall extend to the officers, directors, agents
and employees of the Trustee. 
 Without prejudice to any other rights available to the Trustee under applicable law, when the
Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 6.01(i) or Section 6.01(j) occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any bankruptcy, insolvency or similar laws. 
 Section 7.07. Officers’
Certificate as Evidence. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to
taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness and bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 7.08. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined
capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
  

 38 

 Section 7.09. Resignation or Removal of Trustee. (a) The Trustee may at any time
resign by giving written notice of such resignation to the Company and by mailing notice thereof to the Holders at their addresses as they shall appear on the Note Register. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee
shall have been so appointed and have accepted appointment within sixty days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any
court of competent jurisdiction for the appointment of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 6.11, on behalf of himself and all
others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the following shall occur: 
 (i) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign
after written request therefor by the Company or by any such Holder, or 
 (ii) the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 
 then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of
Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with
Section 8.04, may at any time remove the Trustee and nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the Company objects thereto, in which
case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as in Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
  

 39 

 (d) Any resignation or removal of the Trustee and appointment of a successor trustee
pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. 
 Section 7.10. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights
and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights
and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of
Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06. 
 No successor
trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08. 
 Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee,
at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders at their addresses as they shall appear on the Note Register. If the Company fails to mail
such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
 Section 7.11. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate
trust business of the Trustee (including the administration of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided
that in the case of any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of Section 7.08. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any

  

 40 

 
successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the
successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to
adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
 Section 7.12. Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions
from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of,
the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer that the Company has indicated to the Trustee
should receive such application actually receives such application, unless any such officer shall have consented in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the
Trustee shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be taken or omitted. 
 ARTICLE 8 
 CONCERNING THE HOLDERS

 Section 8.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage
in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the
Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, including through an
electronic system for tabulating consents operated by the Depositary for the Notes (such action becoming effective, except as herein otherwise expressly provided, when such instruments or evidence of electronic consents are delivered to the Trustee
and the Company), or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Notes, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as
the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of solicitation of such action. 
  

 41 

 Section 8.02. Proof of Execution by Holders. Subject to the provisions of
Section 7.01, Section 7.02 and Section 9.05, proof of the execution of any instrument by a Holder or its agent or proxy and proof of the holding by any Person of any of the Notes shall be sufficient if made in accordance with such
reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any
Holders’ meeting shall be proved in the manner provided in Section 9.06. 
 Section 8.03. Who Are Deemed Absolute
Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the
absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or
on account of the principal of and (subject to Section 2.03) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent
nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge
the liability for monies payable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the
Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the
provisions of this Indenture. 
 Section 8.04. Notes Disregarded. In determining whether the Holders of the requisite
aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Company shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any
such direction, consent, waiver or other action only Notes that a Responsible Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this
Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company or a Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company
shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01,
the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination. 
  

 42 

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

Holders shall be by written ballot on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the outstanding principal amount of the Notes held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the
meeting. A record in duplicate of the proceedings of each meeting of Holders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken
thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the principal amount of the
Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
 Any record so
signed and verified shall be conclusive evidence of the matters therein stated. 
 Section 9.07. No Delay of Rights by
Meeting. Nothing contained in this Article 9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in
the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes. 
 ARTICLE 10 
 SUPPLEMENTAL INDENTURES 
 Section 10.01. Supplemental Indentures Without Consent of Holders. The Company, when authorized by the resolutions of the Board of
Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes: 
 (a) to cure any ambiguity, mistake, omission, defect or inconsistency that does not adversely affect Holders of the Notes; 
 (b) to provide for the assumption by a Successor Company of the obligations of the Company under this Indenture pursuant to Article 11;

 (c) to add guarantees with respect to the Notes; 
 (d) to secure the Notes; 
 (e) to add to the covenants for the benefit of the Holders or surrender any right or power conferred upon the Company; 
 (f) to make any change that does not adversely affect the rights of any Holder; 
  

 45 

 (g) to add additional events of default with respect to the Notes; 
 (h) provide for Global Notes in addition to, or in place of, Physical Notes; or 
 (i) to conform the provisions of this Indenture or the Notes to the “Description of notes” section of the Offering Memorandum.

 Upon the written request of the Company, the Trustee is hereby authorized to join with the Company in the execution of any
such supplemental indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by
the provisions of this Section 10.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of Section 10.02. 
 Section 10.02. Supplemental Indentures with Consent of Holders. With the consent (evidenced as provided in Article 8) of the Holders
of at least a majority in aggregate principal amount of the Notes then outstanding (determined in accordance with Article 8 and including, without limitation, consents obtained in connection with a repurchase of, or tender offer or exchange offer
for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the
consent of each Holder of an outstanding Note affected, no such supplemental indenture shall: 
 (a) reduce the principal amount
of Notes whose Holders must consent to an amendment or waiver; 
 (b) reduce the rate of or extend the stated time for payment
of interest on any Note; 
 (c) reduce the principal of or extend the Maturity Date of any Note; 
 (d) make any change that adversely affects the conversion rights of any Notes; 
 (e) reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the Holders the Company’s

 (f) make any Note payable in a money other than that stated in the Note; 
 (g) change the ranking of the Notes;

  

 46 

 (h) impair the right of any Holder to receive payment of principal of, and interest on, such
Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Note; or 
 (i) make any change to the subordination provisions of this Indenture if such change would adversely affect the rights of Holders. 
 Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject
to Section 10.05, the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 
 Holders do not
need under this Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company
shall mail to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

 Section 10.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the
provisions of this Article 10, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the
Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be
part of the terms and conditions of this Indenture for any and all purposes. 
 Section 10.04. Notation on Notes. Notes
authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 10 may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental
indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 17.10) and delivered in exchange for the Notes
then outstanding, upon surrender of such Notes then outstanding. 
 Section 10.05. Evidence of Compliance of Supplemental
Indenture to Be Furnished to Trustee. In addition to the documents required by Section 17.05, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed
pursuant hereto complies with the requirements of this Article 10 and is permitted or authorized by this Indenture.

 ARTICLE 11 
 CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 
 Section 11.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 11.02, the Company shall not
consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of its assets to another Person, unless: 
 (a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States of
America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, all of the obligations of the Company under the Notes and this Indenture; and 
 (b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this
Indenture. 
 In the case of a sale, conveyance, transfer or lease to one or more of the Company’s Subsidiaries of all or substantially all
of the Company’s assets, the Notes will remain convertible into cash based on the Daily VWAP of the Common Stock, subject to the provisions described in Section 13.06. 
 Section 11.02. Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or
lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid
interest on all of the Notes, the due and punctual payment of any cash due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor
Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, except in the case of a lease of all or substantially all of the Company’s properties and assets.
Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and
delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee
for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had
been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company” in the
first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 11 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person
shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture. 
  

 48 

 In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes
in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 Section 11.03. Opinion of Counsel to Be Given Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the
provisions of this Article 11. 
 ARTICLE 12 
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS 
 Section 12.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or accrued and
unpaid interest on any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, or
because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and
understood that this Indenture and the Notes are solely corporate obligations, and that no personal liability whatsoever shall attach to, or be incurred by, any incorporator, stockholder, employee, agent Officer or director, as such, past, present
or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, because of the incurring of the indebtedness hereby authorized or under or by reason of any of the obligations,
covenants, promises or agreements contained in this Indenture or in any of the Notes, or to be implied herefrom or therefrom, and that all liability, if any, of that character against every such incorporator, stockholder, employee, agent, Officer
and director is, by the acceptance of the Notes and as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes expressly waived and released. 
 ARTICLE 13 
 CONVERSION OF
NOTES 
 Section 13.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of
this Article 13, each Holder shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of its Notes (i) subject to satisfaction
of the conditions described in Section 13.01(b),

  

 49 

 
at any time prior to the close of business on the Business Day immediately preceding December 15, 2014 under the circumstances and during the periods set forth in Section 13.01(b), and
(ii) irrespective of the conditions described in Section 13.01(b), on or after December 15, 2014 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, into an
amount of cash based on the sum of the Daily Conversion Values of such Notes for each of the 40 consecutive Trading Days during the relevant Observation Period (subject to the settlement provisions of Section 13.02, the “Conversion
Obligation”). 
 (b) (i) Prior to the close of business on the Business Day immediately preceding December 15,
2014, the Notes may be surrendered for conversion into cash during the five Business Day period immediately after any ten consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal
amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock
and the applicable Conversion Rate. The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. If the Company is not then acting as the Bid
Solicitation Agent, the Company shall provide written notice to the Bid Solicitation Agent of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate
contact information for each. The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination; and the Company shall have no obligation
to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price of the Notes) unless a Holder of a Note provides the Company with reasonable evidence that the Trading
Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. Promptly (but in any event within 2 Business Days) after the Company shall
have received such evidence, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price of the Notes beginning
on the next Trading Day and on each successive Trading Day until the Trading Price per Note is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. If (x) the
Company is not acting as Bid Solicitation Agent, and the Company does not, when it is required to, instruct the Bid Solicitation Agent to obtain bids, or if the Company gives such instruction to the Bid Solicitation Agent, and the Bid Solicitation
Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and the Company fails to make such determination, then, in each case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be
less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on each Trading Day of such failure. If the Trading Price condition set forth above has been met, the Company shall so notify the
Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of
the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee). 
  

 50 

 (ii) Prior to the close of business on the Business Day immediately
preceding December 15, 2014, if the Company elects to: 
 (A) issue to all or substantially all holders of
its Common Stock rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance to subscribe for or purchase shares of its Common Stock, at a price per share less than the
average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 
 (B) distribute to all or substantially all holders of its Common Stock the Company’s assets, debt securities or rights
to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date
of announcement for such distribution, 
 then, in either case, the Company shall notify all Holders of the Notes, the Trustee
and the Conversion Agent (if other than the Trustee) at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, the Notes may be surrendered for conversion into cash at
any time until the earlier of (1) the close of business on the Business Day immediately preceding such Ex-Dividend Date and (2) the Company’s announcement that such issuance or distribution will not take place, even if the Notes are
not otherwise convertible at such time. 
 (iii) Prior to the close of business on the Business Day immediately
preceding December 15, 2014, if a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to
Section 14.01, or if 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 cash, securities or other
assets, and that does not also constitute a Fundamental Change, the Notes may be surrendered for conversion into cash at any time from and after the effective date of such transaction until 30 Trading Days after such effective date or, if such
transaction also constitutes a Fundamental Change, until the Scheduled Trading Day immediately prior to the related Fundamental Change Repurchase Date. The Company shall notify Holders, Trustee and Conversion Agent (if other than the Trustee) of the
occurrence of any such transaction or event no later than the effective date thereof. 
 (iv) Prior to the close
of business on the Business Day immediately preceding December 15, 2014, the Notes may be surrendered for conversion into cash during any fiscal quarter commencing after June 30, 2010 (and only during such fiscal quarter), if the

  

 51 

 
Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the
preceding fiscal quarter is greater than or equal to 150% of the applicable Conversion Price on each applicable Trading Day. The Conversion Agent, on behalf of the Company, shall determine at the beginning of each fiscal quarter commencing after
June 30, 2010 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Company and the Trustee if the Notes become convertible in accordance with this clause (iv). 
 Section 13.02. Conversion Procedure; Payment upon Conversion. (a) Except as provided in Section 13.03(b), upon conversion
of any Note, on the third Scheduled Trading Day immediately following the last Trading Day of the relevant Observation Period, the Company shall pay to converting Holders, in respect of each $1,000 principal amount of Notes being converted, cash in
an amount equal to the Settlement Amount. Notwithstanding the foregoing, if any information required in order to calculate the amount of cash payable upon conversion will not be available as of the applicable settlement date, the Company shall
deliver the additional conversion consideration, if any, resulting from that adjustment on the third Scheduled Trading Day after the earliest Trading Day on which such calculation can be made. The Settlement Amount shall be determined by the Company
promptly following the last Trading Day of the Observation Period. Promptly after such determination of the Settlement Amount, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Settlement Amount. The
Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination. 
 (b)
Before any Holder of a Note shall be entitled to convert the same as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to
interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 13.02(g) and, if required, all transfer or similar taxes, if any, as required by Section 13.02(d) and (ii) in the case of
a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”), (2) surrender such
Physical Note, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents,
(4) if required, pay all transfer or similar taxes, if any, as required by Section 13.02(d) and (5) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth
in Section 13.02(g). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 13 on the Conversion Date for such conversion. No Note may be surrendered for conversion by a Holder
thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Note and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 14.02. 
 If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such
Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
  

 52 

 (c) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in subsection (b) above. 
 (d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so
surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or
Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being
different from the name of the Holder of the old Notes surrendered for such conversion. 
 (e) [Intentionally Omitted]

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

(g) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth
below. The Company’s payment of cash in respect of the Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the
Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, if Notes are converted
after the close of business on an Interest Record Date, Holders of such Notes as of the close of business on such Interest Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the
conversion. Notes surrendered for conversion during the period from the close of business on any Interest Record Date to the opening of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of
interest payable on the Notes so converted; provided that no such payment shall be required (1) for conversions following the Interest Record Date immediately preceding the Maturity Date; (2) if the Company has specified a
Fundamental Change Repurchase Date that is after an Interest Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest
exists at the time of conversion with respect to such Note. 
 (h) Upon a conversion of Notes, the Person surrendering such
Notes for conversion shall no longer be a Holder of such Notes. 
 Section 13.03. Adjustment to Cash Due Upon Conversion Upon
a Make-Whole Fundamental Change. (a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, pay a
“Cash Make-Whole Premium” by increasing the

  

 53 

 
Conversion Rate for the Notes so surrendered for conversion, as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole
Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Scheduled Trading Day immediately
prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b) of the definition thereof, the 30th Trading Day
immediately following the Effective Date of such Make-Whole Fundamental Change). 
 (b) Upon conversion of Notes in connection
with a Make-Whole Fundamental Change pursuant to Section 13.01(b)(iii), the Company shall pay solely cash, based on the Conversion Rate as increased to reflect the Cash Make-Whole Premium pursuant to the table set forth below, in accordance
with Section 13.02. The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

 (c) The amount, if any, by which the Conversion Rate is increased to reflect the Cash Make-Whole Premium in connection with a
Make-Whole Fundamental Change shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (as used in such table, the “Effective Date”) and the price
(as used in such table, the “Stock Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described
in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share, in which case the cash due upon conversion shall be paid to Holders on the third Scheduled Trading Day following the Conversion
Date. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the ten Trading Day period ending on, and including, the Scheduled Trading Day immediately preceding the Effective Date of the Make-Whole
Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to
the Conversion Rate where the Ex-Dividend Date of the event occurs, during such ten consecutive Trading Day period. 
 (d) The
Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to
such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The
Conversion Rate adjustment amounts set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 13.04. 
  

 54 

 (e) The following table sets forth the amount, if any, by which the applicable Conversion
Rate shall be increased pursuant to this Section 13.03 for each Stock Price and Effective Date set forth below: 
  

																																	
	 	 	Stock Price
	 Effective Date

 The exact Stock
Prices and Effective Dates may not be set forth in the table above, in which case: 
 (i) if the Stock Price is
between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the amount of the Conversion Rate adjustment shall be determined by a straight-line interpolation between the amount of the Conversion Rate
adjustment set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year; 
 (ii) if the Stock Price is greater than $60.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection
(d) above), no adjustment to the Conversion Rate shall be made; and 
 (iii) if the Stock Price is less than
$15.75 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no adjustment to the Conversion Rate shall be made. 
 Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 63.4920 per $1,000 principal amount of Notes, subject to adjustment in the
same manner as the Conversion Rate pursuant to Section 13.04. 
 (f) Nothing in this Section 13.03 shall prevent an
adjustment to the Conversion Rate pursuant to Section 13.04 in respect of a Make-Whole Fundamental Change.

 Section 13.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted
from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate, at the same time and upon the same terms as holders of the
Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 13.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the applicable Conversion
Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 
 (a) If the Company
exclusively issues shares of Common Stock as a dividend or distribution on shares of its Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula: 
  

							
		 	CR’ = CR0 ×	 	OS’
 OS0
	  	
		 	 	  	

 where, 
  

					
	CR0	 	    =    	  	the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the opening of business
on the effective date of such share split or share combination, as applicable;
			
	CR’	 	=	  	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date or effective date;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the opening of business on such Ex-Dividend Date or effective date; and
			
	OS’	 	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Any adjustment made under this Section 13.04(a) shall become effective immediately after the opening of business on the Ex-Dividend Date for such
dividend or distribution, or immediately after the opening of business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 13.04(a) is declared but not so paid
or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared. 
 (b) If the Company issues to all or substantially all holders of its Common Stock any rights, options
or warrants entitling them for a period of not more than 45 calendar days after the announcement date of such issuance to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Last Reported Sale
Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

  

							
		 	CR’ = CR0 ×	 	OS0 + X
 OS0 + Y
	  	
		 	 	  	

 where, 
  

					
	CR0	 	    =    	  	the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such issuance;
			
	CR’	 	=	  	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date;

  

 56 

					
	OS0	 	    =    	  	the number of shares of Common Stock outstanding immediately prior to the opening of business on such Ex-Dividend Date;
			
	X	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale
Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 13.04(b) shall become effective immediately after the opening of business on the Ex-Dividend Date for such
issuance. To the extent such rights, options or warrants are not exercised prior to their expiration or termination, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the
issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the
Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred. 
 For purposes of
this Section 13.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10
consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any
consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property or rights, options or
warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions, rights, options or warrants as to which an adjustment was effected pursuant to
Section 13.04(a) or Section 13.04(b), (ii) dividends or distributions paid exclusively in cash, and (iii) Spin-Offs as to which the provisions set forth below in this Section 13.04(c) shall apply (any of such shares of
Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased
based on the following formula: 
  

							
		 	CR’ = CR0 ×	 	      SP0      
 SP0 - FMV
	  	
		 	 	  	

 where, 
  

					
	CR0	 	    =    	  	the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such distribution;

  

 57 

					
	CR’	 	    =    	  	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date;
			
	SP0	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for
such distribution; and
			
	FMV	 	=	  	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for
such distribution.

 If the Board of Directors determines the “FMV” (as defined above) of any
distribution for purposes of this Section 13.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the closing sale prices in such market over the same period used in computing the Last
Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution. Notwithstanding the foregoing, if “FMV” (as defined above) is
equal to or greater than “SP0” (as defined above),
in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount of
Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for the distribution.

 Any increase made under the portion of this Section 13.04(c) above shall become effective immediately after the opening
of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared. 
 With respect to an adjustment pursuant to this Section 13.04(c) where there has been a payment of a dividend
or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, where such Capital Stock or similar equity interest is
listed or quoted (or will be listed or quoted upon consummation of the spin-off) on a national securities exchange or reasonably comparable non-U.S. equivalent (a “Spin-Off”), the Conversion Rate shall be increased based on the
following formula: 
  

							
		 	CR’ = CR0 ×	 	FMV0 + MP0

 MP0
	  	
		 	 	  	

 where, 
  

					
	CR0	 	    =    	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;

  

 58 

					
	CR’	 	    =    	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	 	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock
(determined for purposes of the definition of Last Reported Sale Price as if such Capital Stock or similar equity interest were the Common Stock) over the first 10 consecutive Trading-Day period after, and including, the Ex-Dividend Date of the
Spin-Off (the “Valuation Period”); and
			
	MP0	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last day of the Valuation Period; provided that in respect of any conversion during the Valuation Period,
references in the portion of this Section 13.04(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in
determining the applicable Conversion Rate in respect of such lesser number of Trading Days. 
 For purposes of this
Section 13.04(c) (and subject in all respect to Section 13.09), rights, options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital
Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with
such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.04(c) (and no
adjustment to the Conversion Rate under this Section 13.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate
adjustment (if any is required) to the Conversion Rate shall be made under this Section 13.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are
subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be
deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise
by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect
thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 13.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have
been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate
shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders
of Common Stock

  

 59 

 
with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or
purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been
issued. 
 For purposes of Section 13.04(a), Section 13.04(b) and this Section 13.04(c), if any dividend or
distribution to which this Section 13.04(c) is applicable also includes one or both of: 
 (A) a dividend or distribution
of shares of Common Stock to which Section 13.04(a) is applicable (the “Clause A Distribution”); or 
 (B)
a dividend or distribution of rights, options or warrants to which Section 13.04(b) is applicable (the “Clause B Distribution”), 
 then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 13.04(c) is applicable (the “Clause C
Distribution”) and any Conversion Rate adjustment required by this Section 13.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to
immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 13.04(a) and Section 13.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the
“Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B
Distribution shall be deemed not to be “outstanding immediately prior to the opening of business on such Ex-Dividend Date or effective date” within the meaning of Section 13.04(a) or “outstanding immediately prior to the opening
of business on such Ex-Dividend Date” within the meaning of Section 13.04(b). 
 (d) If the Company pays any cash
dividend or distribution to all or substantially all holders of the Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  

							
		 	CR’ = CR0 ×	 	    SP0    
 SP0 - C
	  	
		 	 	  	

 where, 
  

					
	CR0	 	    =    	  	the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR’	 	=	  	the Conversion Rate in effect immediately after the opening of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	 	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

  

 60 

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

 The adjustment to the Conversion Rate pursuant to this Section 13.04(d) shall become effective immediately after the opening of business on the Ex-Dividend Date for such dividend or distribution.
Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares
of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such
cash dividend or distribution. If such dividend or distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for the Common Stock, other than
an odd-lot offer, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the 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 shall be increased based on the following formula: 
  

							
		 	CR’ = CR0 ×	 	AC + (SP’ × OS’)
 OS0 × SP’
	  	
		 	 	  	

 where, 
  

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

  

 61 

					
	SP’	 	    =    	  	the average of the Last Reported Sale Prices of the Common Stock over the 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 under this Section 13.04(e) shall occur at the close of
business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days immediately
following, and including, the expiration date of any tender or exchange offer, references in this Section 13.04(e) with respect to 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 in determining the applicable Conversion Rate in respect of such lesser number of Trading Days. 
 (f) In addition to those adjustments required by subsections (a), (b), (c), (d) and (e) of this Section 13.04, and to the extent permitted by applicable law, the Company from time to time
may (but is not required to) increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, the Company may (but
is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar
event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall mail to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least one day prior
to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 
 (g) Notwithstanding anything to the contrary in this Article 13, the applicable Conversion Rate shall not be adjusted: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any such plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or
future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries; 
 (iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection
and outstanding as of the date the Notes were first issued; 
 (iv) for a change in the par value of the Common
Stock; 
  

 62 

 (v) except as described above in subsections (a) through (e) of
this Section 13.04, for ordinary course of business stock repurchases, including, but not limited to, structured or derivative transactions, pursuant to a stock repurchase program approved by the Board of Directors; or 
 (vi) for accrued and unpaid interest, if any. 
 (h) All calculations and other determinations under this Article 13 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. No adjustment to the
applicable Conversion Rate shall be required unless the adjustment would require an increase or decrease of at least 1% of the applicable Conversion Rate. If the adjustment is not made because the adjustment does not change the applicable Conversion
Rate by 1% or more, then the adjustment that is not made shall be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to affected Notes
(i) on the Conversion Date for any Notes and (ii) on each of the 40 consecutive Trading Days beginning on, and including, the 42nd Scheduled Trading Day immediately preceding the Maturity Date. 
 (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent
if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly
after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
 (j) For purposes of this Section 13.04, the number of shares of Common Stock at any time outstanding shall not include shares held in
the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock. 
 Section 13.05. Adjustments of Prices. Whenever any provision of this Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs or the Daily Conversion Values over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole
Fundamental Change), the Company shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the
event occurs, at any time during the period from which such Last Reported Sale Prices, the Daily VWAPs or the Daily Conversion Values are to be calculated. 
  

 63 

 Section 13.06. Effect of Recapitalizations, Reclassifications and Changes of the Common
Stock. 
 (a) In the case of: 
 (i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination), 
 (ii) any consolidation, merger or combination involving the Company, 
 (iii) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the
Company and the Company’s Subsidiaries, or 
 (iv) any binding share exchange, 
 in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities or other property or assets
(including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, upon conversion the Settlement Amount shall continue to be paid in solely cash;
provided, however, that the Daily VWAP shall be calculated based on the value of a unit of the amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of one
share of Common Stock immediately prior to such Merger Event would have owned or been entitled to receive upon the occurrence of such transaction (the “Reference Property”, with each “unit of Reference Property”
meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing
Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(f) providing for such change in the right to convert each $1,000 principal amount of Notes. 
 For purposes of the foregoing, if the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more
than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property used to determine the amount of cash into which the Notes will be convertible shall be deemed to be the
weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer
to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after
such determination is made. 
 Such supplemental indenture described in the second immediately preceding paragraph shall provide
for adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 13 in the judgment of the Board of Directors or the board of directors of the successor or purchasing Person. If, in the case of any
Merger Event, the Reference Property includes securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in

  

 64 

 
such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes
as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable the provisions providing for the repurchase rights set forth in Article 14.

 (b) In the event the Company shall execute a supplemental indenture pursuant to Section 13.06(a), the Company shall
promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash, securities or other property or asset that will comprise the Reference Property after any such Merger Event, any
adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed
to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

 (c) The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 13.06.
None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash as set forth in Section 13.01 and Section 13.02 prior to the effective date of such Merger Event. 
 (d) The above provisions of this Section shall similarly apply to successive Merger Events. 
 Section 13.07. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or
responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with
respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any securities or property or cash upon the surrender of any Note for the purpose of conversion or to
comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 13.06 relating either to the kind or amount of securities or property (including cash) receivable by Holders upon the conversion of their
Notes after any event referred to in such Section 13.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with

  

 65 

 
respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 13.01(b) has occurred that makes the Notes
eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 13.01(b) with respect to the commencement or termination of such conversion
rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as
shall be provided for in Section 13.01(b). 
 Section 13.08. Notice to Holders Prior to Certain Actions. In case of
any: 
 (a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to
Section 13.04 or Section 13.09; or 
 (b) Merger Event; or 
 (c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries; 
 then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed
with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record
are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or
any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up. 
 Section 13.09. Stockholder Rights Plans. To the extent that the Company has a rights plan in effect prior to any conversion of the
Notes and the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all
holders of Common Stock, shares of Capital Stock of the Company, evidences of indebtedness, assets, property, rights, options or warrants as provided in Section 13.04(c), subject to readjustment in the event of the expiration, termination or
redemption of such rights. 
 Section 13.10. Exchange in Lieu of Conversion. Notwithstanding anything herein to the
contrary, when a Holder surrenders Notes for conversion, the Company may direct the Conversion Agent to surrender, on or prior to the second Business Day immediately following the applicable Conversion Date (assuming for purposes of this
Section 13.10, and for the purpose of determining the related Observation Period, that the date such Holder surrenders such Notes

  

 66 

 
for conversion is the Conversion Date for such Notes), such Notes to a financial institution designated by the Company for exchange in lieu of conversion. In order to accept any Notes
surrendered for conversion, the designated financial institution must agree to pay to the Conversion Agent for payment to such Holder, in exchange for such Notes, all of the cash due upon conversion, as provided under this Article 13. By the
close of business on the second Business Day immediately following the applicable Conversion Date, the Company will notify the Holder surrendering Notes for conversion that it has directed the designated financial institution to make an exchange in
lieu of conversion. 
 If the designated financial institution accepts any such Notes, it will pay the cash due upon conversion
to the Conversion Agent, and the Conversion Agent will pay such cash to such Holder on the third Scheduled Trading Day immediately following the last Trading Day of the applicable Observation Period. Any Notes exchanged by the designated institution
will remain outstanding. If the designated financial institution agrees to accept any Notes for exchange but does not timely deliver the related cash, or if such designated financial institution does not accept the Notes for exchange, the Company
shall convert the Notes and pay the cash due on the third Scheduled Trading Day immediately following the last day of the applicable Observation Period, in accordance with this Article 13 (based on such assumed Conversion Date as described above).

 The Company’s designation of a financial institution to which the Notes may be submitted for exchange does not require
the financial institution to accept any Notes (unless the financial institution has separately made an agreement with the Company). The Company may, but is not obligated to, enter into a separate agreement with the designated financial institution
that would compensate it for any such transactions. 
 ARTICLE 14 
 REPURCHASE OF NOTES AT OPTION OF HOLDERS 
 Section 14.01. Repurchase at Option of Holders upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior
to the Maturity Date, then each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion of the principal amount thereof, that is equal to $1,000 or an
integral multiple of $1,000, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company
Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to but excluding the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless
the Fundamental Change Repurchase Date is after an Interest Record Date but on or prior to the Interest Payment Date to which such Interest Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid
interest to Holders of record on such Interest Record Date and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 14. 
  

 67 

 (b) Repurchases of Notes under this Section 14.01 shall be made, at the option of the
Holder thereof, upon: 
 (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering
interests in Global Notes, if the Notes are Global Notes, in each case on or before the close of business on the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date; and 
 (ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent (together with all necessary endorsements
for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes to the Paying Agent, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case on or before the close of
business on the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date. 
 The Fundamental Change
Repurchase Notice in respect of any Notes to be repurchased shall state: 
 (i) in the case of Physical Notes,
the certificate numbers of the Notes to be delivered for repurchase; 
 (ii) the portion of the principal amount
of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and 
 (iii) that the Notes are
to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture; 
 provided, however, that
if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 14.01 shall have the right to withdraw, in whole or in part, such
Fundamental Change Repurchase Notice at any time prior to the close of business on the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance
with Section 14.02. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change
Repurchase Notice or written notice of withdrawal thereof. 
 (c) On or before the 20th calendar day after the occurrence of the
effective date of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”)
of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. Such notice shall be by first class mail or, in the case of Global Notes, in accordance with the
applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall

  

 68 

 
publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the
Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 
 (ii) the date of
the Fundamental Change; 
 (iii) the last date on which a Holder may exercise the repurchase right pursuant to
this Article 14; 
 (iv) the Fundamental Change Repurchase Price; 
 (v) the Fundamental Change Repurchase Date; 
 (vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 
 (vii) if applicable, the applicable Conversion Rate and any adjustments to the applicable Conversion Rate; 
 (viii) if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a
Holder may be converted into cash only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and 
 (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes
pursuant to this Section 14.01. 
 At the Company’s request, the Trustee shall give such notice in the Company’s
name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. 
 (d) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such
acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such
Notes). The Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the
Fundamental Change Repurchase Price with respect to such Notes) and shall deem to be cancelled any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary, in which case, upon such return or
cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
  

 69 

 Section 14.02. Withdrawal of Fundamental Change Repurchase Notice. (a) A
Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 14.02 at any time prior to the
close of business on the Scheduled Trading Day immediately preceding the Fundamental Change Repurchase Date, specifying: 
 (i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted, 
 (ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted, and 
 (iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice,
which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that if the Notes
are Global Notes, the notice must comply with appropriate procedures of the Depositary. 
 Section 14.03. Deposit of
Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in
Section 4.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price.
Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the close of business on the Scheduled Trading Day immediately
preceding the Fundamental Change Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in Article 14) and (ii) the time
of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Article 14 by mailing checks for the amount payable to the Holders of such Notes
entitled thereto as they shall appear in the Note Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee
shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price. 
 (b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or
portions thereof that are to be repurchased on such Fundamental Change Repurchase Date, then (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has
been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price). 
  

 70 

 (c) Upon surrender of a Note that is to be repurchased in part pursuant to
Section 14.01, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered. 
 Section 14.04. Covenant to Comply with Applicable Laws upon Repurchase of Notes. In connection with any repurchase offer pursuant to
a Fundamental Change Repurchase Notice, the Company will, if required: 
 (a) comply with the provisions of Rule 13e-4, Rule
14e-1 and any other tender offer rules under the Exchange Act; 
 (b) file a Schedule TO or any successor or similar schedule;
and 
 (c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase
the Notes; 
 in each case, so as to permit the rights and obligations under this Article 14 to be exercised in the time and in the manner
specified in this Article 14. 
 ARTICLE 15 
 NO REDEMPTION 
 Section 15.01. No Redemption.
The Notes shall not be redeemable by the Company prior to Maturity, and no sinking fund is provided for the Notes. 
 ARTICLE 16

 SUBORDINATION OF NOTES 
 Section 16.01. Notes Subordinate to Senior Indebtedness. The Company covenants and agrees, and each Holder of a Note, whether upon
original issue or upon registration of transfer, assignment or exchange thereof, by its acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article 16, the indebtedness represented
by the Notes and the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Settlement Amount due upon conversion of, and accrued and unpaid interest on, all Notes and all other amounts and claims owing
on and with respect to each and all of the Notes and all obligations of the Company under this Indenture (collectively, the “Subordinated Obligations”) are hereby expressly made subordinate and junior in right of payment to the
prior payment in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, of all Senior Indebtedness, and that said subordination is for the benefit of the holders of Senior Indebtedness and they and or each of them
severally may enforce such subordination. The Notes will rank pari passu in right of payment with all other Senior Subordinated Indebtedness of the Company and senior in right of payment to all Subordinated Indebtedness of the Company.

  

 71 

 Section 16.02. Payment Over of Proceeds upon Dissolution, Etc. In the event of (a)
any dissolution, insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets,
whether voluntary or involuntary, or (b) any winding up, liquidation or dissolution of the Company, whether voluntary or involuntary, or (c) any assignment for the benefit of creditors of the Company or any other marshalling of assets and
liabilities of the Company, then in any such event, upon any payment or distribution of the assets or securities of the Company, the holders of Senior Indebtedness shall be entitled to receive payment in full, in cash or other payment satisfactory
to the holders of Senior Indebtedness, of all amounts due or to become due on or in respect of all Senior Indebtedness before the Holders are entitled to receive any payment or distribution on account of the Subordinated Obligations, and to that end
the holders of Senior Indebtedness or their representative or representatives or the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, shall be entitled to receive
from the liquidating trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, ratably according to the aggregate amounts remaining unpaid on account of the
Senior Indebtedness held or represented by each, to the extent necessary to make payment in full in cash of all Senior Indebtedness remaining unpaid, for application to the payment thereof, any payment or distribution of any kind or character,
whether in cash, property or securities, which may be payable or deliverable in respect of the Subordinated Obligations in any such case, proceeding, dissolution, liquidation or other winding up or event, assignment or marshalling. 
 The consolidation of the Company with, or the merger of the Company with or into, or sale, conveyance, transfer or lease of all or
substantially all of its assets to another Person, or the liquidation or dissolution of the Company following the sale, conveyance, transfer or lease of all or substantially all of its assets to another Person, in each case, upon the terms and
conditions set forth in Article 11, shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshaling of assets and liabilities of the Company for the purposes of this
Section 16.02 if, as a part of such consolidation, merger, sale, conveyance, transfer or lease, as the case may be, the Person formed by such consolidation or into which the Company is merged, or which acquires by sale, conveyance or transfer
or lease all or substantially all of the Company’s assets, as the case may be, complies with the conditions set forth in Article 11. 
 Section 16.03. No Payment When Senior Indebtedness in Default. 
 (a) The Company
may not make any payment of or distribution with respect to the Subordinated Obligations, nor may the Company acquire any Notes, if: 
 (i) a payment default with respect to any Senior Indebtedness has occurred and is continuing with respect thereto; or 
  

 72 

 (ii) a default (other than a default referred to in the preceding clause
(i)) with respect to any Designated Senior Indebtedness has occurred and is continuing that permits holders of such Designated Senior Indebtedness to accelerate the maturity thereof and either such default is the subject of judicial proceedings or
the Trustee or the Company receives a written notice that blocks payment under the Notes (a “Payment Blockage Notice”) from a holder of more than $15 million principal amount of Designated Senior Indebtedness (or a representative of
holders who collectively hold more than $15 million principal amount of Designated Senior Indebtedness). 
 (b) If the Trustee
or the Company receives a Payment Blockage Notice, then a similar notice received within nine months thereafter relating to the same default on the same issue of Designated Senior Indebtedness shall not be effective for purposes of this
Section 16.03. 
 (c) The Company may resume payments of and distributions with respect to the Subordinated Obligations,
and may acquire Notes, if and when: 
 (i) in the case of any default referred to in Section 16.03(a)(i),
such default is cured or waived or ceases to exist; or 
 (ii) in the case of any default referred to in
Section 16.03(a)(ii), the earlier of (A) the date such default is cured, waived or ceases to exist, and (B) the date that is 179 days after the receipt by the Trustee or the Company of the Payment Blockage Notice, 
 in each case, so long as this Indenture otherwise permits the payment or acquisition at that time. 
 (d) If any Notes are declared due and payable prior to their stated maturity as a result of an Event of Default, then the Company shall
promptly notify holders of Senior Indebtedness of such acceleration and the Company may not make any payment on, or distribution with respect to, the Subordinated Obligations until the earlier of (i) the date that is 120 calendar days after such
acceleration occurs, and (ii) the payment in full in cash of all Senior Indebtedness, but in either case, only if this Indenture otherwise permits such payment or distribution at that time. 
 (e) In the event that, notwithstanding the foregoing provisions, any payment or distribution of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or otherwise), prohibited by this Article 16, shall be received by the Trustee or the Holders before all Senior Indebtedness is paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness or their representative or representatives,
or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution, or provision therefor,
to or for the holders of such Senior Indebtedness. 
  

 73 

 Section 16.04. Payment Permitted If No Default. Nothing contained in this Article 16
or any other provision relating to subordination elsewhere in this Indenture or in any of the Notes shall prevent the Company, at any time except in the circumstances described in Section 16.02 or Section 16.03, from making any payment on,
or distribution with respect to, the Subordinated Obligations as provided in this Indenture. No provision contained in this Indenture or the Notes shall affect the Company’s obligation, which is absolute and unconditional, to pay the Notes when
due (whether on an Interest Payment Date (solely in respect of interest due), at maturity, on a Fundamental Change Repurchase Date or upon conversion). The subordination provisions set forth in this Article 16 do not prevent the occurrence of any
Default or Event of Default. 
 Section 16.05. Subrogation to Rights of Holders of Senior Indebtedness. Subject to the
payment in full of all Senior Indebtedness in cash, and until the Notes are paid in full, the Holders shall be subrogated (equally and ratably with the holders of all other Senior Subordinated Indebtedness) to the rights of the holders of such
Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness to the extent that payments and distributions otherwise payable to Holders have been applied to the payment of Senior
Indebtedness as provided by this Article 16. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders or the Trustee would be entitled, except
for the provisions of this Article 16, and no payments over pursuant to the provisions of this Article 16 to the holders of Senior Indebtedness by Holders or the Trustee, shall, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders, be deemed to be a payment or distribution by the Company to or on account of the Notes. 
 Section
16.06. Provisions Solely to Define Relative Rights. The provisions of this Article 16 are and are intended solely for the purpose of defining the relative rights of the Holders on the one hand and the holders of Senior Indebtedness on the
other hand. Nothing contained in this Article 16 or elsewhere in this Indenture or in the Notes is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders, the obligation of the
Company, which is absolute and unconditional, to pay to the Holders the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Settlement Amount due upon conversion of, and accrued and unpaid interest on, the Notes, as
the case may be, as provided in this Indenture as and when the same shall become due and payable in accordance with their terms; (b) affect the relative rights against the Company of the Holders and any creditors of the Company other than the
holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Note from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 16 of the
holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder. If the Company fails, as a result of this Article 16, to pay to the Holders the principal (including the
Fundamental Change Repurchase Price, if applicable) of, the Settlement Amount due upon conversion of, or any accrued and unpaid interest on, the Notes, as the case may be, as provided in this Indenture as and when the same shall become due and
payable in accordance with their terms, such failure shall nevertheless constitute a Default or an Event of Default. 
 Section
16.07. Trustee To Effectuate Subordination. Each Holder of a Note by its acceptance thereof authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in
this Article 16 and appoints the Trustee its attorney-in-fact for any and all such purposes. 
  

 74 

 Section 16.08. No Waiver of Subordination Provisions. No right of any present or
future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by
any such holder, or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 
 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders, without incurring responsibility to the Holders and without impairing or releasing the subordination provided in this Article 16 or the obligations hereunder of the Holders to the
holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew, exchange, increase or alter, Senior Indebtedness, or otherwise amend, modify or
supplement in any manner or waive any term relating to Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness or any security thereof or guarantee thereof is outstanding, including, without
limitation, any modifications to interest rates or fees or dates of payment of interest, fees or principal or to financial or other covenants or events of default, as well as any release of any collateral, or other waiver or forbearance;
(ii) sell, exchange, release, surrender, realize upon, enforce or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior
Indebtedness; (iv) exercise or refrain from exercising any rights against the Company and any other Person; (v) apply any and all sums received from time to time to the Senior Indebtedness; provided that if any Senior Indebtedness
is amended to provide that it shall be subordinated to any other Senior Indebtedness, such amended Senior Indebtedness shall no longer be considered Senior Indebtedness for purposes of this Indenture. 
 The provisions of this Article 16 shall continue to be effective or be reinstated, as the case may be, if at any time any payment of the
Senior Indebtedness is rescinded or must otherwise be returned by the holder thereof upon the insolvency, bankruptcy or reorganization of the Company or otherwise, all as though such payment had not been made. 
 Section 16.09. Amendments to Subordination Provisions. Any Senior Indebtedness will continue to be Senior Indebtedness and will be
entitled to the benefits of the subordination provisions set forth in this Article 16 irrespective of any amendment, modification or waiver of any of such subordination provisions. 
 Section 16.10. Notice to Trustee. The Company shall give prompt written notice to a Responsible Officer of the Trustee of any fact
known to the Company that would prohibit the making of any payment to or by the Trustee in respect of the Notes. Notwithstanding the provisions of this Article 16 or any other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts which would prohibit the making of any payment to or distribution by the Trustee in respect of the Notes, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from
the Company or a holder of

  

 75 

 
Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 7.01, shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 16.10 at least one Business Day prior to the date upon which by the terms hereof any
money may become payable for any purpose, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received
and shall not be affected by any notice to the contrary which may be received by it within one Business Day prior to such date. 
 Subject to the provisions of Section 7.01, the Trustee shall be entitled to rely conclusively on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee therefor) to
establish that such notice has been given by a holder of Senior Indebtedness (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to this Article 16 (although the Trustee is not obligated to make such determination), the Trustee may request such Person to furnish evidence to the reasonable satisfaction
of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 16,
and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 Section 16.11. Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the
Company referred to in this Article 16, the Trustee, subject to the provisions of Section 7.01, and the Holders shall be entitled to conclusively rely upon any order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of
creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 16. 
 Section 16.12. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness and (subject to Section 16.10 hereof) shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders or to the Company or to any other Person cash, property or
securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 16 or otherwise. 
 Section
16.13. Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 16 with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 16 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.06. 
  

 76 

 Section 16.14. Article Applicable to Paying Agents. In case at any time any Paying
Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article 16 shall in such case (unless the context otherwise requires) be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article 16 in addition to or in place of the Trustee; provided, however, that Section 16.13 shall not apply
to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
 Section 16.15. No Senior
Subordinated Indebtedness. The Company shall not create, incur, issue, assume, guarantee or otherwise become liable with respect to any indebtedness that is subordinate or junior in right of payment to the Senior Indebtedness and senior in right
of payment to the Subordinated Obligations. For this purpose, unsecured indebtedness will not be deemed subordinate or junior to indebtedness secured by a lien merely because it is unsecured, and Senior Indebtedness will not be deemed subordinate or
junior to any other Senior Indebtedness merely because it has a junior priority with respect to the same collateral.

called for under the Notes. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, the Trading Price of the Notes, accrued interest payable on the Notes and the Conversion Rate of the
Notes. The Company shall make all these calculations in good faith and, absent manifest error,

of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of Notes upon the
request of that Holder at the sole cost and expense of the Company.

 KNIGHT
CAPITAL GROUP, INC., a corporation duly organized and validly existing under the laws of the State of Delaware (the “Company,” which term includes any successor corporation or other entity under the Indenture referred to on the

forth in the Purchase Agreement)), in accordance with the rules and procedures of the Depositary, on March 15, 2015, and interest thereon as set forth below. 
 This Note shall bear interest at the rate of 3.50% per year from March 19, 2010, or from the most recent date on which interest had been paid or provided for to, but excluding, the next
scheduled Interest Payment Date until March 15, 2015. Interest is payable semi-annually in arrears on each March 15 and September 15, commencing on September 15, 2010, to Holders of record at the close of business on the

payable pursuant to Section 4.06(d), which will accrue immediately upon the requirement to pay such Additional Interest as described in Section 4.06(d)). 
 Additional Interest will be payable as set forth in Section 4.06(d), Section 4.06(e) and Section 6.03 of the within-mentioned Indenture, and any reference to interest on, or in respect of,
any Note therein shall be deemed to include Additional Interest if, in such context, Additional Interest is, was or would be payable pursuant to any of such Section 4.06(d), Section 4.06(e) or Section 6.03 and any express mention of
the payment of Additional Interest in any provision therein shall not be construed as excluding Additional Interest in those provisions thereof where such express mention is not made. 
 Any Defaulted Amounts shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable
law, from, and including, the relevant payment date to, but excluding, the date on which such Defaulted Amounts shall have been paid by the Company, at its election, in accordance with Section 2.03(c) of the Indenture. 
 The Company shall pay the principal of and interest on this Note, so long as such Note is a Global Note, in immediately available funds to
the Depositary or its nominee, as the case may be, as the registered Holder of such Note. As provided in and subject to the provisions of the Indenture, the Company shall pay the principal of any Notes (other than Notes that are Global Notes) at the

 [FORM OF REVERSE OF NOTE] 
 KNIGHT CAPITAL GROUP, INC. 
 3.50% Cash Convertible Senior
Subordinated Note due 2015 
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 3.50% Cash
Convertible Senior Subordinated Notes due 2015 (the “Notes”), limited to the aggregate principal amount of $325,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Notes purchased by the
Initial Purchasers pursuant to the exercise of their option to purchase additional Notes as set forth in the Purchase Agreement) all issued or to be issued under and pursuant to an Indenture dated as of March 19, 2010 (the
“Indenture”), between the Company and Deutsche Bank Trust Company Americas (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the
Indenture. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of,
and interest on, all Notes may be declared due and payable, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions and certain exceptions set forth in the Indenture. 
 Subject to the terms and conditions
of the Indenture, the Company will make all payments and deliveries in respect of (a) the Fundamental Change Repurchase Price and (b) the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a
Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 
 The Notes are subordinated to all Senior Indebtedness and are pari passu in right of payment to all Senior Subordinated
Indebtedness of the Company and senior in right of payment to all Subordinated Indebtedness of the Company. Each holder of this Note, whether upon original issue or upon registration of transfer, assignment or exchange thereof, by accepting the
same, agrees to the subordination provisions set forth in Article 16 of the Indenture and authorizes the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and appoints the
Trustee his attorney-in-fact for any and all such purposes. 
 The Indenture contains provisions permitting the Company and the
Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority
in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
  

 A-6 

 No reference herein to the subordination provisions of the Indenture and no provision of
this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay (i) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (ii) accrued and unpaid
interest on, and (iii) the cash due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed. 
 The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof,
and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the
Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the
name of the Holder of the old Notes surrendered for such exchange. 
 The Notes are not subject to redemption through the
operation of any sinking fund or otherwise. 
 Upon the occurrence of a Fundamental Change, the Holder has the right, at such
Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to
the Fundamental Change Repurchase Price. 
 Subject to the provisions of the Indenture, the Holder hereof has the right, at its
option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion
thereof that is $1,000 or an integral multiple thereof, into cash at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 
 Terms used in this Note and defined in the Indenture are used herein as therein defined.
