 Exhibit 10.1 

LSC COMMUNICATIONS, INC. 
 2016 PERFORMANCE INCENTIVE
PLAN 
 (as adopted by the Board of Directors on April 6, 2017 and approved by the stockholders on May 18, 2017) 

 

	I.	General 

 1. Plan. To provide incentives to officers, other employees and
other persons providing services to LSC Communications, Inc. (the “Company”) through rewards based upon the ownership or performance of the common stock, par value $0.01 per share, of the Company (“common stock”) or other
performance measures, the Committee hereinafter designated may grant cash or bonus awards, stock options, stock appreciation rights (“SARs”), restricted stock, stock units or combinations thereof, to eligible participants, on the terms and
subject to the conditions stated in this Amended and Restated 2016 Performance Incentive Plan (the “Plan”). This Amended and Restated 2016 Performance Incentive Plan (i) replaces the Existing Company Plans for awards granted on or
after the Effective Date and (ii) amends and restates the Company’s 2016 Performance Incentive Plan in its entirety effective as of the Effective Date. In addition, to provide incentives to members of the Board of Directors (the
“Board”) who are not employees of the Company (“non-employee directors”), such non-employee directors are eligible to receive awards as set forth in Article V of the Plan. For purposes of the Plan, references to employment by or
service to the Company also means employment by or service to a direct or indirect majority-owned subsidiary of the Company and employment by or service to any other entity designated by the Board or the Committee in which the Company has a direct
or indirect equity interest. Capitalized terms not defined herein shall have the meanings specified in the applicable award agreement. 

2. Eligibility. Officers and other employees of, and other persons providing services to the Company (“participants”)
shall be eligible, upon selection by the Committee, to receive cash or bonus awards, stock options, SARs, restricted stock and stock units, either singly or in combination, as the Committee, in its discretion, shall determine. In addition,
non-employee directors shall receive awards on the terms and subject to the conditions stated in the Plan. 
 3. Limitation on
Shares to be Issued. Subject to adjustment as provided in Section 5 of this Article I, 3,500,000 shares of common stock shall be available under the Plan, reduced by the aggregate number of shares of common stock which become subject to
outstanding bonus awards, stock options, SARs which are not granted in tandem with or by reference to a stock option (“free-standing SARs”), restricted stock awards and stock unit awards. Shares subject to a grant or award under the Plan
(including shares awarded under the Plan prior to the date of this amendment and restatement) which are not issued or delivered, by reason of the expiration, termination, cancellation or forfeiture of all or a portion of the grant or award or the
settlement of the grant or award in cash shall again be available for future grants and awards under the Plan; provided, however, that for purposes of this sentence, stock options and SARs granted in tandem with or by reference to a stock
option granted prior to the grant of such SARs (“tandem SARs”) shall be treated as one grant. Shares tendered or withheld upon exercise of an option, vesting of restricted stock or stock units, settlement of an SAR or upon any other event
to pay exercise price or tax withholding, or shares purchased by the Company using the proceeds of the exercise 

 
a stock option, shall not be available for future issuance under the Plan. In addition, upon exercise of an SAR, the total number of shares remaining available for issuance under the Plan shall
be reduced by the gross number of shares for which the SAR is exercised. 
 For the purpose of complying with Section 162(m) of
the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations thereunder, the maximum number of shares of common stock with respect to which options or SARs or a combination thereof may be granted during any
calendar year to any person shall be 1,500,000, subject to adjustment as provided in Section 5 of this Article I; provided, however, that for purposes of this sentence, stock options and tandem SARs shall be treated as one grant. If the
Plan becomes effective, no new grants shall be made under any equity plan of the Company that is in effect as of the date immediately prior to the date of stockholder approval of the Plan (the “Existing Company Plans”) and all such
Existing Company Plans shall be terminated, provided, however, that such termination shall have no effect on any outstanding awards granted under any Existing Company Plan. 

Shares of common stock to be issued may be treasury shares reacquired by the Company or authorized and unissued shares, or a combination of
both. 
 4. Administration of the Plan. The Plan shall be administered by a Committee designated by the Board (the
“Committee”), provided that the Board may designate a separate committee, also meeting the requirements set forth in the following sentence, to administer Article V hereof. Each member of the Committee shall be a director that the Board
has determined to be (i) an “outside director” within the meaning of Section 162(m) of the Code, (ii) a “Non-Employee Director” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended
(the “Exchange Act”) and (iii) “independent” within the meaning of the rules of the principal stock exchange on which the common stock is traded. The Committee shall, subject to the terms of the Plan, select eligible
participants for grants and awards; determine the form of each grant and award, either as cash, bonus awards, stock options, SARs, restricted stock awards, stock unit awards or a combination thereof; and determine the number of shares or units
subject to the grant or award, the fair market value of the common stock or units when necessary, the timing and conditions of vesting, exercise or settlement, whether dividends or dividend equivalents accrue under any award, and all other terms and
conditions of each grant and award, including, without limitation, the form of instrument evidencing the grant or award. Notwithstanding the foregoing and subject to Article V, all stock option awards, SARs, restricted stock awards and stock unit
awards, other than awards that are subject to performance-based vesting conditions over a performance period of at least one year, shall have a minimum vesting period of at least three years from the date of grant (such vesting may, in the
discretion of the Committee, occur in full at the end of such period or may occur in specified installments over such period, provided that no more than 40% of any particular award may vest by the end of the first year following the date of grant
and no more than 80% of any particular award may vest by the end of the second year following the date of grant); provided, however, that the Committee may provide for early vesting upon the death, permanent and total disability, retirement
or involuntary termination of service of the award recipient. Notwithstanding the foregoing, up to 5% of the shares available for grant under the Plan may be granted with a minimum vesting schedule that is shorter than that mandated in this
Section 4 of Article I. The Committee may establish rules and regulations for the administration of the Plan, interpret the Plan, and impose, 

  
 -2- 

 
incidental to a grant or award, conditions with respect to competitive employment or other activities not inconsistent with the Plan. All such rules, regulations, interpretations and conditions
shall be conclusive and binding on all parties. Notwithstanding anything in this Plan to the contrary and subject to Section 5 of this Article I, to the extent required by the New York Stock Exchange, or any other stock exchange on which shares
of Common Stock are traded, the Committee will not amend, replace, cancel or surrender in exchange for cash or other consideration (in each case that has the effect of reducing the exercise price) any previously granted option or SAR in a
transaction that constitutes a repricing, without the approval of the stockholders of the Company. 
 Each grant and award shall be
evidenced by a written instrument and no grant or award shall be valid until an agreement is executed by the Company and such grant or award shall be effective as of the effective date set forth in the agreement. The Committee may delegate some or
all of its power and authority hereunder to the chief executive officer or other executive officer of the Company as the Committee deems appropriate; provided, however, that the Committee may not delegate its power and authority with regard
to (i) the selection for participation in the Plan of (A) a person who is a “covered employee” within the meaning of Section 162(m) of the Code or who, in the Committee’s judgment, is likely to be a covered employee at
any time during the period a grant or award hereunder to such participant would be outstanding, (B) an officer or other person subject to Section 16 of the Exchange Act or (C) a person who is not an employee of the Company or
(ii) decisions concerning the time, pricing or amount of a grant or award to a participant, officer or other person described in clause (i) above. A majority of the Committee shall constitute a quorum. The acts of the Committee shall be
either (i) acts of a majority of the members of the Committee present at any meeting at which a quorum is present or (ii) acts approved in writing by all of the members of the Committee without a meeting. 

Notwithstanding anything to the contrary contained herein, the Board may, in its sole discretion, at any time and from time to time, grant
Awards or administer the Plan. In any such case, the Board will have all of the authority and responsibility granted to the Committee herein. 

5. Adjustments. In the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination,
exchange of shares, liquidation, spin-off or other similar change in capitalization or event affecting the Company or its common stock, or any distribution to holders of the Company’s common stock other than a regular cash dividend, the number,
class and kind of securities (including, for this purpose, securities of any other entity that is a party to such transaction) available under the Plan, the specific share limitations otherwise set forth in the Plan, the number, class and kind of
securities (including, for this purpose, securities of any other entity that is a party to such transaction) subject to each outstanding bonus award, the number, class and kind of securities (including, for this purpose, securities of any other
entity that is a party to such transaction) subject to each outstanding stock option and the purchase price per security and the terms of each outstanding SAR shall be appropriately adjusted by the Committee, such adjustments to be made in the case
of outstanding stock options and SARs without an increase in the aggregate purchase price or base price. For purposes of the Plan, the fair market value of the common stock on a specified date shall be the closing market price of the common stock on
such date, or, if no such trading in the common stock occurred on such date, then on the next preceding date when such trading occurred, or as otherwise determined by the Committee. 

  
 -3- 

 6. Effective Date and Term of Plan. The Plan shall be submitted to the stockholders
of the Company for approval at the next meeting of stockholders held following the Board’s adoption of the Plan and, if approved, shall become effective on the date of such stockholder approval (the “Effective Date”). The Plan shall
terminate on the date on which shares are no longer available for grants or awards under the Plan, unless terminated prior thereto by action of the Board; provided, however that if the Plan itself has not previously terminated, Section 1
of Article V shall terminate on the date that is ten years from the date of stockholder approval of the Plan. No further grants or awards shall be made under the Plan after termination, but termination shall not affect the rights of any participant
under any grants or awards made prior to termination. 
 7. Amendments. The Plan may be amended or terminated by the
Board in any respect except that no amendment may be made without stockholder approval if stockholder approval is required by applicable law, rule or regulation, including Section 162(m) of the Code, or such amendment would increase (subject to
Section 5 of this Article I) the number of shares available under the Plan or would amend the prohibition on repricing of awards set forth in Section 4 of this Article I or otherwise permit the repricing of awards granted hereunder. No
amendment may impair the rights of a holder of an outstanding grant or award without the consent of such holder. 
 8.
Indemnification. No member of the Board, Committee or any person to whom the Committee delegates its powers, responsibilities or duties in writing, including by resolution (each such person, a “Covered Person”), will have any
liability to any person (including any grantee) for any action taken or omitted to be taken or any determination made with respect to the Plan or any award, except as expressly provided by statute. Each Covered Person will be indemnified and held
harmless by the Company against and from: 
 (a) any loss, cost, liability or expense (including attorneys’ fees) that may be imposed
upon or incurred by such Covered Person in connection with or resulting from any action, suit or proceeding to which such Covered Person may be a party or in which such Covered Person may be involved by reason of any action taken or omitted to be
taken under the Plan or any award agreement, in each case, in good faith and 
 (b) any and all amounts paid by such Covered Person, with
the Company’s approval, in settlement thereof, or paid by such Covered Person in satisfaction of any judgment in any such action, suit or proceeding against such Covered Person, provided that the Company will have the right, at its own expense,
to assume and defend any such action, suit or proceeding and, once the Company gives notice of its intent to assume the defense, the Company will have sole control over such defense with counsel of the Company’s choice. 

The foregoing right of indemnification will not be available to a Covered Person to the extent that a court of competent jurisdiction in a final judgment or
other final adjudication, in either case, not subject to further appeal, determines that the acts or omissions of such Covered Person giving rise to the indemnification claim resulted from such Covered Person’s bad faith, fraud or willful
misconduct. The foregoing right of indemnification will not be exclusive of any other 

  
 -4- 

 
rights of indemnification to which Covered Persons may be entitled under the Company’s articles of incorporation or bylaws, pursuant to any individual indemnification agreements between such
Covered Person and the Company, as a matter of law, or otherwise, or any other power that the Company may have to indemnify such persons or hold them harmless. 
  

	II.	Bonus Awards 

 1. Form of Award. Bonus awards, whether performance awards
or fixed awards, may be made to eligible participants in the form of (i) cash, whether in an absolute amount or as a percentage of compensation, (ii) stock units, each of which is substantially the equivalent of a share of common stock but
for the power to vote and, if the Committee so determines, in its sole discretion, the entitlement to an amount equal to dividends or other distributions otherwise payable on a like number of shares of common stock, (iii) shares of common stock
issued to the participant but forfeitable and with restrictions on transfer in any form as hereinafter provided or (iv) any combination of the foregoing. 

2. Performance Awards. (a) Awards may be made in terms of a stated potential maximum dollar amount, percentage of
compensation or number of units or shares, with such actual amount, percentage or number to be determined by reference to the level of achievement of corporate, sector, business unit, division, individual or other specific performance goals over a
performance period of not less than one nor more than ten years, as determined by the Committee. 
 (b) Performance
awards will be determined based on the attainment of written objective performance goals approved by the Committee for a performance period established by the Committee (i) while the outcome for that performance period is substantially
uncertain and (ii) no more than 90 days after the commencement of the performance period to which the performance goal relates or, if the performance period is less than one year, the number of days which is equal to 25% of the relevant
performance period. At the same time as the performance goals are established, the Committee will prescribe a formula to determine the amount of the performance award that may be payable based upon the level of attainment of the performance goals
during the performance period. 
 (c) Following the completion of each performance period, the Committee will have the sole
discretion to determine whether the applicable performance goals, including the corporate financial target under the Company’s Annual Incentive Plan, have been met with respect to a given grantee and, if they have, will so certify in writing
and ascertain the amount of the applicable performance award. No performance award will be paid for such performance period until such certification is made by the Committee. The amount of the performance award actually paid to a given grantee may
be less (but not more) than the amount determined by the applicable performance goal formula, at the discretion of the Committee. The amount of the performance award determined by the Committee for a performance period will be paid to the grantee at
such time as determined by the Committee in its sole discretion after the end of such performance period. 
 (d) In no event
shall any participant receive a payment with respect to any performance award if the minimum threshold performance goals requirement applicable to the payment is not achieved during the performance period. 

  
 -5- 

 (e) If the Committee desires that compensation payable pursuant to performance
awards be “qualified performance-based compensation” within the meaning of Section 162(m) of the Code, then with respect to such performance awards, for any calendar year (i) the maximum compensation payable pursuant to any such
performance awards granted during such year, to the extent payment thereunder is determined by reference to shares of common stock (or the fair market value thereof), shall not exceed 900,000 shares of common stock (or the fair market value
thereof), subject to adjustment as set forth in Section 5 of Article I, and (ii) the maximum compensation payable pursuant to any such performance awards granted during such year, to the extent payment is not determined by reference to
shares of common stock, shall not exceed $9,000,000. The limits set forth in this Section (e) of Article II shall be proportionately increased for performance periods that are longer than 12 months. 

(f) The Committee may provide in any agreement evidencing a performance award under the Plan that the Committee shall retain
sole discretion to reduce the amount of or eliminate any payment otherwise payable to a participant with respect to any performance award. If so provided in any agreement evidencing a performance award, the Committee may exercise such discretion by
establishing conditions for payments in addition to the performance goals, including the achievement of financial, strategic or individual goals, which may be objective or subjective, as it deems appropriate. 

(g) For purposes of the Plan, “performance goals” means the objectives established by the Committee which shall be
satisfied or met during the applicable performance period as a condition to a participant’s receipt of all or a part of a performance-based award under the Plan. The performance goals shall be tied to one or more of the following business
criteria, determined with respect to the Company or the applicable sector, business unit or division: net sales; cost of sales; gross profit; earnings from operations; earnings before interest, taxes, depreciation and amortization; earnings before
income taxes; earnings before interest and taxes; cash flow measures; return on equity; return on assets; return on net assets employed; return on capital; working capital; leverage ratio; stock price measures; enterprise value; safety measures; net
income per common share (basic or diluted); EVATM (Economic Value Added, which represents the cash operating earnings of the Company after deducting a charge for capital employed); cost reduction objectives or, in the case of awards not intended
to be “qualified performance-based compensation” within the meaning of Section 162(m) of the Internal Revenue Code, any other similar criteria established by the Plan Committee for the applicable performance period. The Committee may
provide in any agreement evidencing a performance award under the Plan that the Committee shall amend or adjust the performance goals or other terms or conditions of an outstanding award in recognition of unusual or nonrecurring events. If the
Committee desires that compensation payable pursuant to any award subject to performance goals be “qualified performance-based compensation” within the meaning of Section 162(m) of the Code, the performance goals (i) shall be
established by the Committee no later than 90 days after the beginning of the applicable performance period (or such other time designated by the Internal Revenue 

  
 -6- 

 
Service) and (ii) shall satisfy all other applicable requirements imposed under Treasury Regulations promulgated under Section 162(m) of the Code, including the requirement that such
performance goals be stated in terms of an objective formula or standard. 
 3. Fixed Awards. Awards may be made which are not
contingent on the achievement of specific objectives, but are contingent on the participant’s continuing in the Company’s employ for a period specified in the award. 

4. Rights with Respect to Restricted Shares. If shares of restricted common stock are subject to an award, the participant shall
have the right, unless and until such award is forfeited or unless otherwise determined by the Committee at the time of grant, to vote the shares and to receive dividends thereon from the date of grant and the right to participate in any capital
adjustment applicable to all holders of common stock; provided, however, that (i)distributions with respect to shares of common stock and (ii) regular cash dividends with respect to shares of restricted common stock, in each case,
whether subject to time-based or performance-based vesting conditions, shall be deposited with the Company and shall be subject to the same restrictions as the shares of restricted common stock with respect to which any such distribution or dividend
was made. 
 During the restriction period, the shares subject to a restricted stock award shall be held in book entry form, with the
restrictions, terms and conditions duly noted, or alternatively a certificate or certificates representing restricted shares shall be registered in the holder’s name or the name of a nominee of the Company and may bear a legend, in addition to
any legend which may be required under applicable laws, rules or regulations, indicating that the ownership of the shares of common stock represented by such certificate is subject to the restrictions, terms and conditions of the Plan and the
agreement relating to the shares of restricted common stock. All such certificates shall be deposited with the Company, together with stock powers or other instruments of assignment (including a power of attorney), each endorsed in blank with a
guarantee of signature if deemed necessary or appropriate, which would permit transfer to the Company of all or a portion of the shares of common stock subject to the award in the event such award is forfeited in whole or in part. Upon termination
of any applicable restriction period, including, if applicable, the satisfaction or achievement of applicable objectives, and subject to the Company’s right to require payment of any taxes, the requisite number of shares of common stock shall
be delivered to the holder of such award. 
 5. Rights with Respect to Stock Units. If stock units are credited to a
participant pursuant to an award, then, except as otherwise provided by the Committee in its sole discretion, amounts equal to dividends and other distributions otherwise payable on a like number of shares of common stock after the crediting of the
units (unless the record date for such dividends or other distributions precedes the date of grant of such award) shall be credited to a notional account for the participant and shall be subject to the same vesting conditions as the related stock
unit award and interest may be credited on the account at a rate determined by the Committee. The Committee may grant awards of stock units in such amounts and subject to such terms and conditions as the Committee may determine. A grantee of a stock
unit will have only the rights of a general unsecured creditor of the Company, until delivery of shares, cash or other securities or property is made as specified in the applicable award agreement. On the delivery date specified in the award
agreement, the grantee of each stock unit not previously forfeited or terminated will receive one share of common stock, cash or other securities or property equal in value to a share of common stock or a combination thereof, as specified by the
Committee. 

  
 -7- 

 6. Events Upon Vesting. At the time of vesting of an award made pursuant to this Article
II, (i) the award (and any dividend equivalents, other distributions and interest which have been credited), if in units, shall be paid to the participant either in shares of common stock equal to the number of units, in cash equal to the fair
market value of such shares, or in such combination thereof as the Committee shall determine, (ii) the award, if a cash bonus award, shall be paid to the participant either in cash, or in shares of common stock with a then fair market value equal to
the amount of such award, or in such combination thereof as the Committee shall determine and (iii) shares of restricted common stock issued pursuant to an award shall be released from the restrictions. 

 

	III.	Stock Options 

 1. Options for Eligible Participants. Options to purchase
shares of common stock may be granted to such eligible participants as may be selected by the Committee. These options may, but need not, constitute “incentive stock options” under Section 422 of the Code. To the extent that the
aggregate fair market value (determined as of the date of grant) of shares of common stock with respect to which options designated as incentive stock options are exercisable for the first time by an optionee during any calendar year (under the Plan
or any other plan of the Company, or any parent or subsidiary) exceeds the amount (currently $100,000) established by the Code, such options shall not constitute incentive stock options. No incentive stock options may be granted under the Plan after
the earlier of the tenth anniversary of (a) the date the Plan is approved by the Board or (b) the effective date of the Plan. 

2. Number of Shares and Purchase Price. The number of shares of common stock subject to an option and the purchase price per
share of common stock purchasable upon exercise of the option shall be determined by the Committee; provided, however, that the purchase price per share of common stock shall not be less than 100% of the fair market value of a share of common
stock on the date of grant of the option; provided, further, that if an incentive stock option shall be granted to any person who, on the date of grant of such option, owns capital stock possessing more than ten percent of the total combined
voting power of all classes of capital stock of the Company (or of any parent or subsidiary) (a “Ten Percent Holder”), the purchase price per share of common stock shall be the price (currently 110% of fair market value) required by the
Code in order to constitute an incentive stock option. 
 3. Exercise of Options. The period during which options
granted hereunder may be exercised shall be determined by the Committee; provided, however, that no stock option shall be exercised later than ten years after its date of grant; provided further, that if an incentive stock option shall
be granted to a Ten Percent Holder, such option shall not be exercisable more than five years after its date of grant. The Committee may, in its discretion, establish performance measures which shall be satisfied or met as a condition to the grant
of an option or to the exercisability of all or a portion of an option. The Committee shall determine whether an option shall become exercisable in cumulative or non-cumulative installments and in part or in full at any time. An exercisable option,
or portion thereof, may be exercised only with respect to whole shares of common stock. 

  
 -8- 

 An option may be exercised (i) by giving written notice to the Company (or following other
procedures designated by the Company) specifying the number of whole shares of common stock to be purchased and accompanied by payment therefor in full (or arrangement made for such payment to the Company’s satisfaction) either (A) in
cash, (B) in previously owned whole shares of common stock (for which the optionee has good title free and clear of all liens and encumbrances) having a fair market value, determined as of the date of exercise, equal to the aggregate purchase
price payable by reason of such exercise, (C) by authorizing the Company to withhold whole shares of Common Stock that would otherwise be delivered having a fair market value, determined as of the date of exercise, equal to the aggregate
purchase price payable by reason of such exercise, (D) in cash by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise, (E) to the extent expressly authorized by the Committee, via
a cashless exercise arrangement with the Company or (F) a combination of (A) and (B), (ii) if applicable, by surrendering to the Company any SARs which are canceled by reason of the exercise of the option and (iii) by executing
such documents as the Company may reasonably request. The Committee shall have the sole discretion to disapprove of an election pursuant to clause (D). Any fraction of a share of common stock which would be required to pay such purchase price shall
be disregarded and the remaining amount due shall be paid in cash by the optionee. No shares of common stock shall be delivered until the full purchase price therefor has been paid. 

4. No Dividend Equivalent Rights. No dividend equivalents shall be paid or shall accrue with respect to any shares of common
stock subject to an option.  
  

	IV.	Stock Appreciation Rights 

 1. Grants. Free-standing SARs entitling the
grantee to receive cash or shares of common stock having a fair market value equal to the appreciation in market value of a stated number of shares of common stock from the date of grant to the date of exercise of such SARs, or in the case of tandem
SARs, from the date of grant of the related stock option to the date of exercise of such tandem SARs, may be granted to such participants as may be selected by the Committee. The holder of a tandem SAR may elect to exercise either the option or the
SAR, but not both. Tandem SARs shall be automatically canceled upon exercise of the related stock option. 
 2. Number of
SARs and Base Price. The number of SARs subject to a grant shall be determined by the Committee. Any tandem SAR related to an incentive stock option shall be granted at the same time that such incentive stock option is granted. The base price of
a tandem SAR shall be the purchase price per share of common stock of the related option. The base price of a free-standing SAR shall be determined by the Committee; provided, however, that such base price shall not be less than 100% of the
fair market value of a share of common stock on the date of grant of such SAR. 
 3. Exercise of SARs. The agreement relating
to a grant of SARs may specify whether such grant shall be settled in shares of common stock (including restricted shares of common stock) or cash or a combination thereof. Upon exercise of an SAR, the grantee shall be paid the excess of the then
fair market value of the number of shares of common stock to which the SAR relates over the base price of the SAR. Such excess shall be paid in cash or in shares of common 

  
 -9- 

 
stock having a fair market value equal to such excess or in such combination thereof as the Committee shall determine. The period during which SARs granted hereunder may be exercised shall be
determined by the Committee; provided, however, no SAR shall be exercised later than ten years after the date of its grant; and provided, further, that no tandem SAR shall be exercised if the related option has expired or has been
canceled or forfeited or has otherwise terminated. The Committee may, in its discretion, establish performance measures which shall be satisfied or met as a condition to the grant of an SAR or to the exercisability of all or a portion of an SAR. The
Committee shall determine whether an SAR may be exercised in cumulative or non-cumulative installments and in part or in full at any time. An exercisable SAR, or portion thereof, may be exercised, in the case of a tandem SAR, only with respect to
whole shares of common stock and, in the case of a free-standing SAR, only with respect to a whole number of SARs. If an SAR is exercised for restricted shares of common stock, the restricted shares shall be issued in accordance with Section 4 of
Article II and the holder of such restricted shares shall have such rights of a stockholder of the Company as determined pursuant to such Section. Prior to the exercise of an SAR for shares of common stock, including restricted shares, the holder of
such SAR shall have no rights as a stockholder of the Company with respect to the shares of common stock subject to such SAR. 
 A tandem
SAR may be exercised (i) by giving written notice to the Company (or following other procedures designated by the Company) specifying the number of whole SARs which are being exercised, (ii) by surrendering to the Company any options which
are canceled by reason of the exercise of such SAR and (iii) by executing such documents as the Company may reasonably request. A free-standing SAR may be exercised (i) by giving written notice to the Company specifying the whole number of
SARs which are being exercised and (ii) by executing such documents as the Company may reasonably request. 
 4. No Dividend
Equivalent Rights. No dividend equivalents shall be paid or shall accrue with respect to any shares of common stock subject to a SAR.  
  

	V.	Awards to Non-Employee Directors 

 1. Annual Grants to Non-Employee
Directors. On the date of the Company’s 2017 annual meeting of stockholders, and on the date of each subsequent annual meeting prior to the termination of this Section 1, the Company shall make an award under the Plan to each
individual who is, immediately following such annual meeting, a non-employee director. Awards granted pursuant to this Section 1 of Article V shall be in the form of stock options, restricted stock, stock units or SARs. The form of such awards,
and the number of shares subject to each such award, shall be determined by a committee meeting the requirements for the Committee described above in Section 4 of Article I in the exercise of its sole discretion. Notwithstanding anything to the
contrary set forth elsewhere in the Plan, an award granted to a non-employee director pursuant to this Section 1 of Article V shall have a minimum vesting period of one year from the date of grant and is subject to the limits on compensation in
Section 3 of this Article V. 
 2. Elective Options for Non-Employee Directors. Each non-employee director may from time
to time elect, in accordance with procedures to be specified by the Committee, to receive in lieu of all or part of any annual base cash retainer fee for services as a director of the Company, any fees for attendance at meetings of the Board or any
committee of the Board and 

  
 -10- 

 
any fees for serving as a member or chairman of any committee of the Board that would otherwise be payable to such non-employee director (“Fees”), an option to purchase shares of common
stock, which option shall have a value (as determined in accordance with the Black-Scholes stock option valuation method) as of the date of grant of such option equal to the amount of such Fees and which shall be subject to all of the terms and
conditions set forth in Article III of the Plan. Notwithstanding anything to the contrary set forth elsewhere in the Plan, an option granted to a non-employee director pursuant to this Section 2 of Article V shall become exercisable in full on
the first anniversary of the date of grant. 
 3. Limits on Compensation to Non-Employee Directors. No non-employee director
of the Company may be granted (in any calendar year) compensation with a value in excess of $900,000, with the value of any equity-based awards based on the accounting grant date value of such award. 

 

	VI.	Other 

 1. Non-Transferability of Options and Stock Appreciation Rights. No
option or SAR shall be transferable other than (i) by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company or (ii) as otherwise set forth in the agreement relating to such
option or SAR. Each option or SAR may be exercised during the participant’s lifetime only by the participant or the participant’s guardian, legal representative or similar person or the permitted transferee of the participant. Except as
permitted by the second preceding sentence, no option or SAR may be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar
process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of any option or SAR, such award and all rights thereunder shall immediately become null and void. 

2. Tax Withholding. The Company shall have the right to require, prior to the issuance or delivery of any shares of common stock or the
payment of any cash pursuant to a grant or award hereunder, payment by the holder thereof of any federal, state, local or other taxes which may be required to be withheld or paid in connection therewith. An agreement may provide that (i) the Company
shall withhold whole shares of common stock which would otherwise be delivered to a holder, having an aggregate fair market value determined as of the date the obligation to withhold or pay taxes arises in connection therewith (the “Tax
Date”), or withhold an amount of cash which would otherwise be payable to a holder, in the amount necessary to satisfy any such obligation or (ii) the holder may satisfy any such obligation by any of the following means: (A) a cash payment to
the Company, (B) delivery to the Company of previously owned whole shares of common stock (which the holder has held for at least six months prior to the delivery of such shares or which the holder purchased on the open market and for which the
holder has good title, free and clear of all liens and encumbrances) having an aggregate fair market value determined as of the Tax Date, equal to the amount necessary to satisfy any such obligation, (C) authorizing the Company to withhold
whole shares of common stock which would otherwise be delivered having an aggregate fair market value determined as of the Tax Date or withhold an amount of cash which would otherwise be payable to a holder, equal to the amount necessary to satisfy
any such liability, (D) in the case of the exercise of an 

  
 -11- 

 
option, a cash payment by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise or (E) any combination of (A), (B) and (C); provided,
however, that the Committee shall have sole discretion to disapprove of an election involving clause (D). An agreement relating to a grant or award hereunder may not provide for shares of common stock to be withheld having an aggregate fair
market value in excess of the minimum amount of taxes required to be withheld. Any fraction of a share of common stock which would be required to satisfy such an obligation shall be disregarded and the remaining amount due shall be paid in cash by
the holder. 
 3. Acceleration Upon Change in Control. If while (i) any performance award or fixed award granted under Article II is
outstanding, (ii) any stock option granted under Article III of the Plan or SAR granted under Article IV of the Plan is outstanding or (iii) any award made to non-employee directors pursuant to Article V (“nonemployee director
awards”) is outstanding: 
 (a) any “person,” as such term is defined in Section 3(a)(9) of the Exchange
Act, as modified and used in Section 13(d) and 14(d) thereof (but not including (i) the Company or any of its subsidiaries, (ii) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any of
its subsidiaries, (iii) an underwriter temporarily holding securities pursuant to an offering of such securities, or (iv) a corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions
as their ownership of stock of the Company) (hereinafter a “Person”) is or becomes the beneficial owner, as defined in Rule 13d-3 of the Exchange Act, directly or indirectly, of securities of the Company (not including in the securities
beneficially owned by such Person any securities acquired directly from the Company or its affiliates, excluding an acquisition resulting from the exercise of a conversion or exchange privilege in respect of outstanding convertible or exchangeable
securities) representing 50% or more of the combined voting power of the Company’s then outstanding securities; or 

(b) during any period of two (2) consecutive years beginning on the date that stockholders approve the Plan, individuals
who at the beginning of such period constitute the Board and any new director (other than a director designated by a Person who has entered into any agreement with the Company to effect a transaction described in Clause (a), (c) or (d) of
this Section) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the
period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or 

(c) a merger or consolidation of the Company with any other corporation (hereinafter, a “Corporate Transaction”) is
consummated, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting
securities of the surviving or acquiring entity), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company, at least 50% of the combined voting power of the voting
securities of the Company or such surviving or acquiring entity outstanding 

  
 -12- 

 
immediately after such merger or consolidation, or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no Person acquires
more than 50% of the combined voting power of the Company’s then outstanding securities; or 
 (d) the stockholders of
the Company approve a plan of complete liquidation of the Company or for the consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets, 

(any of such events being hereinafter referred to as a “Change in Control”), then unless the Committee determines otherwise or as otherwise provided
in the applicable award agreement, if a grantee’s Employment is terminated by the Company or any successor entity thereto without Cause, or the grantee resigns his or her Employment for Good Reason, in either case, on or within two
(2) years after a Change in Control, (i) each award granted to such grantee prior to such Change in Control will become fully vested (including the lapsing of all restrictions and conditions) and, as applicable, exercisable, and
(ii) any shares deliverable pursuant to restricted stock units will be delivered promptly (but no later than 15 days) following such grantee’s termination of Employment. As of the Change in Control date, any outstanding performance awards
shall be deemed earned at the greater of the target level and, to the extent determinable, the actual performance level at the date of the Change in Control with respect to all open performance periods and will cease to be subject to any
further performance conditions but will continue to be subject to time-based vesting following the Change in Control in accordance with the original performance period. In connection with such Change in Control, the Board (as constituted prior to
the Change in Control) may, in its discretion: 
 (i) require that shares of capital stock of the corporation resulting from
or succeeding to the business of the Company pursuant to such Change in Control, or a parent corporation thereof, be substituted for some or all of the shares of common stock subject to an outstanding award, with an appropriate and equitable
adjustment to such award as determined by the Committee in accordance with Section 5 of Article I; and/or 
 (ii)
require outstanding awards, in whole or in part, to be surrendered to the Company by the holder, and to be immediately cancelled by the Company, and to provide for the holder to receive (a) a cash payment in an amount equal to (1) in the
case of an option or an SAR, the number of shares of common stock then subject to the portion of such option or SAR surrendered multiplied by the excess, if any, of the fair market value of a share of common stock as of the date of the Change in
Control, over the exercise price or base price per share of common stock subject to such option or SAR, (2) in the case of a restricted stock award, stock unit award or bonus award denominated in shares of common stock, the number of shares of
common stock then subject to the portion of such award surrendered, multiplied by the fair market value of a share of common stock as of the date of the Change in Control, and (3) in the case of a bonus award denominated in cash, the value of
the bonus award then subject to the portion of such award surrendered; (b) shares of capital stock of the corporation resulting from or succeeding to the business of the Company pursuant to such Change in

  
 -13- 

 
Control, or a parent corporation thereof, having a fair market value not less than the amount determined under clause (a) above; or (c) a combination of the payment of cash pursuant to
clause (a) above and the issuance of shares pursuant to clause (b) above. 
 4. Section 409A. All awards made under
the Plan that are intended to be “deferred compensation” subject to Section 409A will be interpreted, administered and construed to comply with Section 409A, and all awards made under the Plan that are intended to be exempt from
Section 409A will be interpreted, administered and construed to comply with and preserve such exemption. The Board and the Committee will have full authority to give effect to the intent of the foregoing sentence. To the extent necessary to give
effect to this intent, in the case of any conflict or potential inconsistency between the Plan and a provision of any award or award agreement with respect to an award, the Plan will govern. Without limiting the generality of this Section, with
respect to any award made under the Plan that is intended to be “deferred compensation” subject to Section 409A: 

(a) any payment due upon a grantee’s termination of employment will be paid only upon such grantee’s separation from
service from the Company within the meaning of Section 409A; 
 (b) Any payment due upon a Change in Control of the
Company will be paid only if such Change in Control constitutes a “change in ownership” or “change in effective control” within the meaning of Section 409A, and in the event that such Change in Control does not constitute a
“change in the ownership” or “change in the effective control” within the meaning of Section 409A, such award will vest upon the Change in Control and any payment will be delayed until the first compliant date under
Section 409A; 
 (c) any payment to be made with respect to such award in connection with the grantee’s separation from service
from the Company within the meaning of Section 409A (and any other payment that would be subject to the limitations in Section 409A(a)(2)(B) of the Code) will be delayed until six months after the grantee’s separation from service (or
earlier death) in accordance with the requirements of Section 409A; 
 (d) if any payment to be made with respect to such award would
occur at a time when the tax deduction with respect to such payment would be limited or eliminated by Section 162(m) of the Code, such payment may be deferred by the Company under the circumstances described in Section 409A until the
earliest date that the Company reasonably anticipates that the deduction or payment will not be limited or eliminated; 
 (e) to the extent
necessary to comply with Section 409A, any other securities, other awards or other property that the Company may deliver in lieu of shares in respect of an award will not have the effect of deferring delivery or payment beyond the date on which
such delivery or payment would occur with respect to the shares that would otherwise have been deliverable (unless the Committee elects a later date for this purpose in accordance with the requirements of Section 409A); 

  
 -14- 

 (f) with respect to any required consent under an applicable award agreement, if such consent has
not been effected or obtained as of the latest date provided by such award agreement for payment in respect of such award and further delay of payment is not permitted in accordance with the requirements of Section 409A, such award or portion
thereof, as applicable, will be forfeited and terminate notwithstanding any prior earning or vesting; 
 (g) if the award includes a
“series of installment payments” (within the meaning of Section 1.409A-2(b)(2)(iii) of the Treasury Regulations), the grantee’s right to the series of installment payments will be treated as a right to a series of separate
payments and not as a right to a single payment; 
 (h) if the award includes “dividend equivalents” (within the meaning of
Section 1.409A-3(e) of the Treasury Regulations), the grantee’s right to the dividend equivalents will be treated separately from the right to other amounts under the award; and 

(i) for purposes of determining whether the grantee has experienced a separation from service from the Company within the meaning of
Section 409A, “subsidiary” will mean a corporation or other entity in a chain of corporations or other entities in which each corporation or other entity, starting with the Company, has a controlling interest in another corporation or
other entity in the chain, ending with such corporation or other entity. For purposes of the preceding sentence, the term “controlling interest” has the same meaning as provided in Section 1.414(c)-2(b)(2)(i) of the Treasury
Regulations, provided that the language “at least 20 percent” is used instead of “at least 80 percent” each place it appears in Section 1.414(c)-2(b)(2)(i) of the Treasury Regulations. 

5. Restrictions on Shares. Each grant and award made hereunder shall be subject to the requirement that if at any time the
Company determines that the listing, registration or qualification of the shares of common stock subject thereto upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is
necessary or desirable as a condition of, or in connection with, the delivery of shares thereunder, such shares shall not be delivered unless such listing, registration, qualification, consent, approval or other action shall have been effected or
obtained, free of any conditions not acceptable to the Company. The Company may require that certificates evidencing shares of common stock delivered pursuant to any grant or award made hereunder bear a legend indicating that the sale, transfer or
other disposition thereof by the holder is prohibited except in compliance with the Securities Act of 1933, as amended, and the rules and regulations thereunder. 

6. No Right of Participation or Employment. No person (other than non-employee directors to the extent provided in Article V)
shall have any right to participate in the Plan. Neither the Plan nor any grant or award made hereunder shall confer upon any person any right to employment or continued employment by the Company, any subsidiary or any affiliate of the Company or
affect in any manner the right of the Company, any subsidiary or any affiliate of the Company to terminate the employment of any person at any time without liability hereunder. 

7. Rights as Stockholder. No person shall have any right as a stockholder of the Company with respect to any shares of common
stock or other equity security of the Company which is subject to a grant or award hereunder unless and until such person becomes a stockholder of record with respect to such shares of common stock or equity security. 

  
 -15- 

 8. Awards Subject to Clawback. The awards and any cash payment or securities
delivered pursuant to an award are subject to forfeiture, recovery by the Company or other action pursuant to the applicable award agreement or any clawback or recoupment policy which the Company may adopt from time to time, including without
limitation any such policy which the Company may be required to adopt under the Dodd-Frank Wall Street Reform and Consumer Protection Act and implementing rules and regulations thereunder, or as otherwise required by law. 

9. Nonassignability; No Hedging. Unless otherwise provided in an award agreement, no award (or any rights and obligations thereunder)
granted to any person under the Plan may be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of or hedged in violation of the Company policy on hedging, in any manner (including through the use of any cash-settled
instrument), whether voluntarily or involuntarily and whether by operation of law or otherwise, other than by will or by the laws of descent and distribution, and all such awards (and any rights thereunder) will be exercisable during the life of the
grantee only by the grantee or the grantee’s legal representative. Notwithstanding the foregoing, the Committee may permit, under such terms and conditions that it deems appropriate in its sole discretion, a grantee to transfer any award to any
person or entity that the Committee so determines. Any sale, exchange, transfer, assignment, pledge, hypothecation, or other disposition in violation of the provisions of this Section or Company policy will be null and void and any award which is
hedged in any manner will immediately be forfeited. All of the terms and conditions of the Plan and the award agreements will be binding upon any permitted successors and assigns. 

10. Right of Offset. The Company will have the right to offset against its obligation to deliver shares (or other property or cash)
under the Plan or any award agreement any outstanding amounts (including, without limitation, travel and entertainment or advance account balances, loans, repayment obligations under any awards, or amounts repayable to the Company pursuant to tax
equalization, housing, automobile or other employee programs) that the grantee then owes to the Company and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or agreement. Notwithstanding the foregoing, if
an award provides for the deferral of compensation within the meaning of Section 409A of the Code, the Committee will have no right to offset against its obligation to deliver shares (or other property or cash) under the Plan or any award
agreement if such offset could subject the grantee to the additional tax imposed under Section 409A of the Code in respect of an outstanding award. 

11. Governing Law. The Plan, each grant and award hereunder and the related agreement, and all determinations made and actions
taken pursuant thereto, to the extent not otherwise governed by the Code or the laws of the United States, shall be governed by the laws of the State of Delaware and construed in accordance therewith without giving effect to principles of conflicts
of laws. 
 12. Foreign Participants. Notwithstanding any provision of the Plan to the contrary the Committee may, with a view
to both promoting achievement of the purposes of the Plan and complying with (i) provisions of laws in countries outside the United States in which the Company or its subsidiaries operate or have employees and (ii) the rules of any foreign stock

  
 -16- 

 
exchange upon which the common stock may be listed, determine which persons outside the United States shall be eligible to participate in the Plan on such terms and conditions different from
those specified in the Plan as may in the judgment of the Committee be necessary or advisable and, to that end, the Committee may establish sub-plans, modified option exercise procedures and other terms and procedures. 

13. Insider Limits. Notwithstanding any other provision of the Plan, (i) the maximum number of shares of common stock which
may be reserved for issuance to insiders (as defined in the Ontario Securities Act) under the Plan, together with any other previously established or proposed incentive plan, shall not exceed 10% of the outstanding shares of common stock,
(ii) the maximum number of shares of common stock which may be issued to insiders under the Plan, together with any other previously established or proposed incentive plan, within any one year period shall not exceed 10% of the outstanding
shares of common stock, and (iii) the maximum number of shares of common stock which may be issued to any one insider and his or her associates under the Plan, together with any other previously established or proposed incentive plan, within a
one-year period, shall not exceed 5% of the outstanding shares of common stock. 
 14. Waiver of Jury Trial. Each
grantee waives any right it may have to trial by jury in respect of any litigation based on, arising out of, under or in connection with the Plan. 

15. Waiver of Claims. Each grantee of an award recognizes and agrees that before being selected by the Committee to receive an award
the grantee has no right to any benefits under the Plan. Accordingly, in consideration of the grantee’s receipt of any award hereunder, the grantee expressly waives any right to contest the amount of any award, the terms of any award agreement,
any determination, action or omission hereunder or under any award agreement by the Committee, the Company or the Board, or any amendment to the Plan or any award agreement (other than an amendment to the Plan or an award agreement to which his or
her consent is expressly required by the express terms of an award agreement). Nothing contained in the Plan, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship
between the Company and any grantee. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974 (ERISA), as amended. 

16. Severability; Entire Agreement. If any of the provisions of the Plan or any award agreement is finally held to be invalid, illegal
or unenforceable (whether in whole or in part), such provision will be deemed modified to the extent, but only to the extent, of such invalidity, illegality or unenforceability and the remaining provisions will not be affected thereby; provided that
if any of such provisions is finally held to be invalid, illegal, or unenforceable because it exceeds the maximum scope determined to be acceptable to permit such provision to be enforceable, such provision will be deemed to be modified to the
minimum extent necessary to modify such scope in order to make such provision enforceable hereunder. The Plan and any award agreements contain the entire agreement of the parties with respect to the subject matter thereof and supersede all prior
agreements, promises, covenants, arrangements, communications, representations and warranties between them, whether written or oral with respect to the subject matter thereof. 

  
 -17- 

 17. No Liability With Respect to Tax Qualification or Adverse Tax Treatment.
Notwithstanding anything to the contrary contained herein, in no event will the Company be liable to a grantee on account of an award’s failure to (a) qualify for favorable United States or foreign tax treatment or (b) avoid adverse
tax treatment under United States or foreign law, including, without limitation, Section 409A. 
 18. No Third-Party
Beneficiaries. Except as expressly provided in an award Agreement, neither the Plan nor any award agreement will confer on any person other than the Company and the grantee of any award any rights or remedies thereunder. The exculpation and
indemnification provisions of Section 1.8 will inure to the benefit of a Covered Person’s estate and beneficiaries and legatees. 

19. Successors and Assigns of the Company. The terms of the Plan will be binding upon and inure to the benefit of the Company and any
successor entity, including as contemplated by Section 6.3. 
 20. Approval of Plan. The Plan and all grants and awards
made hereunder shall be null and void if the adoption of the Plan is not approved by the affirmative vote of a majority of the shares of common stock present in person or represented by proxy at the next meeting of stockholders following the
Board’s adoption of the Plan.

under the Base Indenture. The Notes shall be designated as the “1.875% Convertible Senior Notes due 2024.” The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is initially limited to
$289,000,000, subject to Section 3.07 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 12.02 or Section 13.04 hereof or
Section 3.4, Section 3.5, Section 3.6 or Section 9.6 of the Base Indenture (as amended, if applicable, by this Second Supplemental Indenture). 

Section 3.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne by such
Notes shall be substantially in the respective forms set forth in Exhibit A, notwithstanding anything in the Base Indenture to the contrary, the terms and provisions of which shall constitute, and are hereby expressly incorporated in and made a part
of the Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of the 

  
 12 

 
Indenture, expressly agree to such terms and provisions and to be bound thereby; provided, however, that to the extent any provision of the Notes conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 
 Any Global Note may be endorsed with or
have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of the Indenture as may be required by the Depositary, or as may be required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any
special limitations or restrictions to which any particular Notes are subject. 
 Any of the Notes may have such letters, numbers or other
marks of identification and such notations, legends or endorsements as the Officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, or as
may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to
conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject. 
 Each Global Note shall
represent such principal amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal
amount of Outstanding Notes represented thereby may from time to time be increased or reduced to reflect repurchases, cancellations, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any
increase or decrease in the amount of Outstanding Notes represented thereby shall be made on the Schedule of Exchanges of Notes to such Global Note 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 the Indenture. 
 Section 3.03. Date and
Denomination of Notes; Payment of Interest. (a) The Notes shall be issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples of $1,000 in excess thereof. Each Note shall be dated
the date of its authentication and shall bear interest from the date specified on the face of such Note. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month. Section 3.10 of the Base Indenture shall, with respect to
the Notes, be superseded in its entirety by this Section 3.03(a), and any reference in the Base Indenture to such Section 3.10 shall, with respect to the Notes, be deemed to refer instead to this Section 3.03(a). 

(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 Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. The principal amount of any Note (x) in the case of any Physical Note, shall be
payable through the Paying Agent at the office or agency designated by the Company maintained for such 

  
 13 

 
purpose in the continental United States of America, which shall initially be the Corporate Trust Office, and (y) in the case of any Global Note, shall be payable by wire transfer of
immediately available funds in accordance with the wire transfer instructions supplied by the Depositary or its nominee from time to time to the Trustee and the Paying Agent (if other than the Trustee). The Company shall pay or cause the Paying
Agent to pay interest (i) on any Physical Notes through the Paying Agent (A) by check mailed to the Holder of these Notes at its address as it appears in the Note Register and (B) to a Holder holding Physical Notes having an aggregate
principal amount of more than $5,000,000, at the application by such Holder in writing to the Company and the Paying Agent (which application shall remain in effect until the Holder provides written notice to the contrary) by wire transfer of
immediately available funds to that Holder’s account within the United States supplied by such Holder from time to time to the Trustee and the Paying Agent (if other than the Trustee) not later than the relevant Regular Record Date, or
(ii) on any Global Notes by wire transfer of immediately available funds in accordance with the wire transfer instructions supplied by the Depositary or its nominee from time to time to the Trustee or the Paying Agent (if other than the
Trustee). The Company shall pay the principal amount of and interest on any Note in money of the United States that at the time of payment is legal tender for payment of public and private debts. Section 3.7(a) of the Base Indenture shall, with
respect to the Notes, be superseded in its entirety by this Section 3.03(b), and any reference in the Base Indenture to such Section 3.7(a) shall, with respect to the Notes, be deemed to refer instead to this Section 3.03(b). 

Section 3.04. Exchange and Registration of Transfer of Notes; Depositary. (a) No service charge shall be imposed by
the Company, the Trustee, the Security Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company or the Trustee may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue
or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or
registration of transfer. Section 3.5(f) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this first paragraph of Section 3.04(a), and any reference in the Base Indenture to such Section 3.5(f) shall, with
respect to the Notes, be deemed to refer instead to this first paragraph of Section 3.04(a). 
 None of the Company, the Trustee or the
Security Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any
Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 13. 

(b)    So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law,
subject to the first paragraph of Section 3.04(d), all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer
and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture (including the restrictions
on transfer set forth herein) and the Applicable Procedures of the Depositary therefor. 

  
 14 

 (c)    Notwithstanding any other provisions of the Indenture (other than the
provisions set forth in this Section 3.04(c)), a Global Note shall not be transferred, in 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 exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the first
paragraph of Section 3.04(d). 
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints
The Depository Trust Company to act as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with
the Trustee as custodian for Cede & Co. 
 Section 3.5(i) of the Base Indenture shall, with respect to the Notes, be superseded in
its entirety by this Section 3.04(c), and any reference in the Base Indenture to such Section 3.5(i) shall, with respect to the Notes, be deemed to refer instead to this Section 3.04(c). 

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

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 3.04(d) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered. 

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 Applicable Procedures of the Depositary and the provisions of the Indenture. 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 

  
 15 

 
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 the Schedule of Exchanges of Notes
to 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, the Paying Agent or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Note
or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 3.5(h) of the Base
Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 3.04(d), and any reference in the Base Indenture to such Section 3.5(h) shall, with respect to the Notes, be deemed to refer instead to this Section 3.04(d).

 (e)    The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for
cancellation in accordance with Section 3.06. 
 Section 3.05. Mutilated, Destroyed, Lost and Stolen Notes.
(a) Section 3.6(c), Section 3.6(d) and Section 3.6(f) of the Base Indenture shall, with respect to the Notes, be superseded in their entirety by Section 3.05(b), and any reference in the Base Indenture to such Section 3.6(c), Section 3.6(d) or
Section 3.6(f) shall, with respect to the Notes, be deemed to refer instead to Section 3.05(b). 
 (b)    No service
charge shall be imposed by the Company, the Trustee, the Security Registrar or the Paying Agent upon the issuance of any substitute Note as provided in Section 3.6 of the Base Indenture, but the Company may require a Holder to pay a sum
sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became
mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 12 shall become mutilated or be destroyed,
lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as
the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for
any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent, of the
destruction, loss or theft of such Note and of the ownership thereof. 
 To the extent permitted by law, all Notes shall be held and owned
upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender. 

  
 16 

 Section 3.06. Cancellation of Notes Paid, Converted, Etc. (a) Section 3.9
of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by Section 3.06(b), and any reference in the Base Indenture to such Section 3.9 shall, with respect to the Notes, be deemed to refer instead to Section
3.06(b). 
 (b)    The Company shall cause all Notes surrendered for the purpose of payment, repurchase, registration of
transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee
shall, upon receipt of a written request in a Company Order, be canceled promptly by it. Except for any Notes surrendered for registration of transfer or exchange, or as otherwise expressly permitted by any of the provisions of the Indenture, no
Notes shall be authenticated in exchange for any Notes surrendered to the Trustee for cancellation. The Trustee shall cancel Notes in accordance with its customary procedures and, after such cancellation, shall deliver a certificate of such
cancellation to the Company, at the Company’s written request in a Company Order. 
 Section 3.07. Additional
Notes; Repurchases. The Company may, without notice to or the consent of the Holders and notwithstanding Section 3.01, reopen this Second Supplemental Indenture and issue additional Notes hereunder with the same terms as the Notes initially
issued hereunder (other than differences in the issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with
the Notes initially issued hereunder for U.S. federal income tax purposes (as determined by the Company in good faith based on the advice of tax counsel) or securities law purposes, such additional Notes shall have a separate CUSIP number. Prior to
the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover those matters required by
Section 1.2(b) of the Base Indenture. In addition, the Company may, to the extent permitted by law, directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether
by the Company or its Subsidiaries or through a privately negotiation transaction or a public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case, without prior
notice to the Holders. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 3.06(b) and, upon
receipt of a Company Order as set forth in Section 3.06(b), the Trustee shall cancel all Notes so surrendered and such Notes shall no longer be considered Outstanding under the Indenture upon their repurchase. 

Section 3.08. Payment of Defaulted Amounts. Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the
relevant payment date 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, and such Defaulted Amounts together with such
interest thereon shall be paid by the Company, at its election in each case, as provided in clause (a) or (b) below: 

(a)    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 

  
 17 

 
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 15 days after the receipt by the Trustee of such notice), 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 10 days and not
less than 5 days prior to the date of the proposed payment, and not less than 5 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 (to be prepared by the Company) of such Defaulted Amounts and the special record date therefor to be sent electronically or 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 sent,
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
(b) of this Section 3.08. 
 (b)    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 3.7(b) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 3.08, and any
reference in the Base Indenture to such Section 3.7(b) shall, with respect to the Notes, be deemed to refer instead to this Section 3.08. 

Section 3.09. 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 shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

ARTICLE 4

Article IV or any Sections thereof and satisfaction and discharge provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 4 and the satisfaction and discharge provisions set forth in this
Article 4. Article XIII of the Base Indenture shall not apply to the Notes. 
 Section 4.02. Satisfaction and
Discharge. This Second Supplemental Indenture (and the Base Indenture with respect to the Notes) 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 instruments prepared by the Company acknowledging satisfaction and discharge of the Indenture, when (x) (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and
which have been replaced, paid or converted as provided in Section 3.05 hereof and Section 3.6 of the Base Indenture) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered

Trust Money. Subject to the provisions of Section 5.03, all cash deposited with the Trustee pursuant to Section 4.02 shall be held in trust and applied by it, in accordance with the provisions of the Notes and the Indenture, to
the payment or satisfaction, as the case may be, either directly or through a Paying Agent (including the Company, if acting as Paying Agent), to the Persons entitled thereto, of the principal and interest or the Company’s Conversion
Obligation, as applicable, for whose payment or satisfaction, as the case may be, such cash has been deposited with the Trustee as contemplated by Section 4.02. Notwithstanding any references herein to delivery by the Company to the Conversion
Agent of shares of Common Stock to be further distributed to applicable Holders of the Notes, it shall be acceptable if such shares of Common Stock are distributed to Holders via an alternate method which is usual and customary with respect to
securities similar to the Notes. 
 ARTICLE 5 

PARTICULAR COVENANTS OF THE COMPANY

 19 

 The Company shall also maintain an office or agency (the “Conversion Agent”) in
the continental United States of America where the Notes may be surrendered for conversion. The Company shall 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 such required office or agency or shall fail to furnish the Trustee with the address thereof, such surrenders may be made at the Corporate Trust Office or the office or agency of the Trustee in the continental United
States of America. The Company hereby initially designates the Trustee as the Conversion Agent and the Corporate Trust Office of the Trustee in the continental United States of America as the office or agency where Notes may be surrendered for
conversion. The Company may also from time to time designate one or more additional conversion agents 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 for such purposes in accordance with this Section 5.01. The Company shall 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 term “Conversion Agent” includes any such additional or other offices or agencies, as applicable. 

The Company shall maintain a Place of Payment in the continental United States of America at all times at which any Note is Outstanding. The
Company shall notify Holders, the Trustee and the Paying Agent and Conversion Agent (if other than the Trustee) within one Business Day of any change in the Place of Payment or any change in the location of the Conversion Agent. 

Section 5.02. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary
to avoid or fill a vacancy in the office of Trustee, shall appoint, in the manner provided in Section 6.10 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder. 

Section 5.03. Provisions as to Paying Agent. (a) Section 10.3(c)(3) of the Base Indenture is hereby amended
with respect to the Notes by replacing the words “such default” therein with “Event of Default”. 

(b)    Subject to any unclaimed property laws, any money deposited with the Trustee or any Paying Agent, or any money and
shares of Common Stock then held by the Company, in trust for the payment of the principal of, accrued and unpaid interest on and the consideration due upon conversion of any Note and remaining unclaimed for two years after such principal, interest
or consideration due upon conversion 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 with
respect to such trust money and shares of Common Stock, shall thereupon cease. Section 10.3(e) of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 5.03(b), and any reference in the Base Indenture to
such Section 10.3(e) shall, with respect to the Notes, be deemed to refer instead to this Section 5.03(b). 

  
 20 

 Section 5.04. Reports. (a) Section 7.4 of the Base Indenture
shall, with respect to the Notes, be superseded in its entirety by this Section 5.04, and any reference in the Base Indenture to such Section 7.4 shall, with respect to the Notes, be deemed to refer instead to this Section 5.04.

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 thereof shall be deemed to be filed with the
Trustee for purposes of this Section 5.04 at the time such documents are filed via the EDGAR system or such successor. If the Notes become convertible into Reference Property consisting in whole or in part of shares of Capital Stock of any
parent company of the Company pursuant to Section 12.07 hereof and such parent company provides a full and unconditional guarantee of the Notes, the filing with the Trustee of the reports that such parent company is required to file with the
Commission as described in this Section 5.04(b) shall be deemed to satisfy the foregoing requirements of this Section 5.04(b). The Trustee shall have no obligation whatsoever as to the filing, timeliness or content of such reports. 

(c)    Delivery of any documents or reports 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

or other law that would prohibit or forgive the Company from paying all or any portion of the principal (including the Fundamental Change Repurchase Price, if applicable) of or interest on the Notes as contemplated herein, wherever enacted, now or
at any time hereafter in force, or that may affect the covenants or the performance of the Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will
not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. Section 5.15 of the Base
Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 5.05, and any reference in the Base Indenture to such Section 5.15 shall, with respect to the Notes, be deemed to refer instead to this

covenants then required to be performed under the Indenture and, if so, specifying each such failure and the nature thereof. 
 In addition,

 Section 6.03. Acceleration; Rescission and Annulment. If one or more Events of
Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order,
rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company or any of its Significant
Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding, by notice in writing to the Company
(and to the Trustee if given by Holders), may declare 100% of the principal 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, notwithstanding anything contained in the Indenture or in the Notes to the contrary. If an Event of Default specified in Section 6.02(i) or Section 6.02(j) with respect to the Company or any of its Significant
Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall automatically become due and payable immediately. 

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have
been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that
payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 6.7 of the Base Indenture, and if (1) rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that
shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.08, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate
principal amount of the Notes then Outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default
shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of
Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment
of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case
may be, the consideration due upon conversion of the Notes. 
 Section 6.04. Additional Interest. Notwithstanding anything in
the Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default 

  
 24 

 
relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company is required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or (ii) the Company’s failure to comply with its obligations as set forth in Section 5.04 shall, for the first 180 days 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 0.25% per annum of the principal amount of the Outstanding Notes for each day during the first 90 days after the occurrence of such an Event
of Default on which such Event of Default is continuing, beginning on, and including, the date on which such an Event of Default first occurs, and at a rate equal to 0.50% per annum of the principal amount of the Outstanding Notes for each day from
the 91st day after the occurrence of such an Event of Default until the 180th day following the occurrence of such an Event of Default on which such Event of Default is continuing. If the Company so elects, such Additional Interest shall be payable
in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 181st
day), such Additional Interest shall cease to accrue and the Notes shall be immediately subject to acceleration as provided in Section 6.03. The provisions of this paragraph shall not affect the rights of Holders of Notes in the event of the
occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 314(a)(1) of the Trust Indenture Act or Section 5.04. In the event the Company does not elect to pay Additional
Interest following such an Event of Default in accordance with this Section 6.04 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided
in Section 6.03. 
 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 described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, and the Trustee and the Paying Agent in writing, 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 6.03. 

Section 6.05. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause
(a) or (b) of Section 6.02 shall have occurred, the Company shall, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any
overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 6.7 of the Base Indenture. If the
Company shall fail to pay such amounts forthwith, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or
final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the
Notes, wherever situated. 
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision
of the Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings. 

  
 25 

 Section 6.06. Application of Monies Collected by Trustee. Any monies or property
collected by the Trustee pursuant to this Article 6 or Article V of the Base Indenture (as amended by this Second Supplemental Indenture with respect to the Notes) with respect to the Notes shall be applied in the following order, at the date or
dates fixed by the Trustee for the distribution of such monies or property, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid (or in accordance with Applicable
Procedures, with respect to Global Notes): 
 First, to the payment of all amounts due the Trustee, including for reimbursement of
expenses of its agents and counsel pursuant to Section 6.7(2) of the Base Indenture, under Section 6.7 of the Base Indenture; 

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

Third, in case the principal of the Outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment
of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion if applicable), 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 accrued and unpaid 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 any 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 any cash due upon conversion) and accrued and unpaid interest; and 
 Fourth, to the payment
of the remainder, if any, to the Company. 
 Section 6.07. 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 or delivery of the consideration due upon conversion, no Holder of any Note shall have any right
by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or
other similar official, or for any other remedy hereunder, unless: 
 (a)    such Holder previously shall have given to
the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided; 

  
 26 

 (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 such security or indemnity, shall have neglected or refused to institute any such action, suit or proceeding; and 

(e)    no written direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been
given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.08, 

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that
no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, 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) (it being understood that the
Trustee shall have no duty to determine whether or not such actions prejudice such Holders). For the protection and enforcement of this Section 6.07, each and every Holder and the Trustee shall be entitled to such relief as can be given either
at law or in equity. 
 Notwithstanding any other provision of the Indenture and any provision of any Note, the right of any Holder to
receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion
of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against
the Company shall not be impaired or affected without the consent of such Holder. 
 Section 6.08. 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 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 6.02, (ii) a failure by the Company to pay or deliver, as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10
cannot 

  
 27 

 
be modified or amended without the consent of each Holder of an Outstanding Note affected. The consent to any such waiver may be obtained, without limitation, in connection with a repurchase of,
or tender or exchange offer for, Notes. 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 6.08, said Default or Event of Default shall for all purposes of the Notes and
the Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Section 5.12(a)(1) of the Base Indenture is hereby
amended with respect to the Notes by inserting immediately prior to the word “satisfactory” the word “reasonably”. 

Section 6.09. Notice of Defaults. If a Default hereunder occurs and is continuing with respect to the Notes and is
known to a Responsible Officer of the Trustee, the Trustee shall send to all Holders of Notes, as their names and addresses appear in the Note Register, notice of such Default within 90 days after a Responsible Officer of the Trustee becomes aware
of such Default, unless such Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable) or
interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as the Trustee in good faith determines that the withholding of
such notice is in the interest of the Holders of Notes. Section 6.2 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this Section 6.09, and any reference in the Base Indenture to such
Section 6.2 shall, with respect to the Notes, be deemed to refer instead to this Section 6.09. 
 Section 6.10.
Undertaking to Pay Costs. All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any
right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;
provided that the provisions of this Section 6.10 (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, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the
Fundamental Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance
with the provisions of Article 12.

1.4(a), Section 1.4(b) and Section 1.4(c) of the Base Indenture shall, with respect to the Notes, be superseded in their entirety by this Article 8, and any reference in the Base Indenture to such Section 1.4(a), Section 1.4(b) or Section 1.4(c)
shall, with respect to the Notes, be deemed to refer instead to this Article 8. 
 Section 8.02. Action by
Holders. Whenever in the Indenture it is provided that the Holders of a specified percentage of the aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or
waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (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, 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, but shall not be
required to, fix in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the date of commencement of
solicitation of such action.

authenticating agent, any Paying Agent, any Conversion Agent and any Security Registrar may deem the Person in whose name a Note shall be registered upon the Note Register (which, for the avoidance of doubt shall initially be Cede & Co. in
the case of a Note held through the Depositary) 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 Security Registrar) for the purpose of receiving payment of or on account of the principal (including any Fundamental Change Repurchase Price) of and (subject to Section 3.03 and Section 3.08) 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 Security Registrar shall be affected by any notice to the contrary. All such
payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or shares of Common Stock so paid or delivered, effective to satisfy and discharge the liability for monies payable or
shares deliverable upon any such Note. Notwithstanding anything to the contrary in the Indenture (including, without limitation, Section 3.8 of the Base 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 the Indenture. 

  
 29 

 Section 8.04. Revocation of Consents; Future Holders Bound. At any time prior to (but
not after) the evidencing to the Trustee, as provided in Section 8.02, of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in the 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 8.05, 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. 
 Section 8.05. Proof of Execution by Holders. Subject to the provisions of Section 6.1 and
Section 6.3 of the Base Indenture and Section 9.05 hereof, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed
by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the Note Register or by a certificate of the Security Registrar. The record of any Holders’ meeting shall be proved in the manner
provided in Section 9.06.

of Holders to take any action specified in Section 9.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the Holders, setting forth the time and the place of such meeting and in general terms
the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 8.02, shall be sent to Holders of such Notes at their addresses as they shall appear on the Note Register. Such notice shall also be
sent to the Company. Such notices shall be sent not less than 20 nor more than 90 days prior to the date fixed for the meeting.

the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice. 

Section 9.03. Call of Meetings by Company or Holders. In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 25% of the aggregate principal amount of the Notes then Outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable detail the action proposed to
be taken at the meeting (and if the Notes are not Global Notes, have provided the Trustee adequate funds to cover the costs of distributing such notice), and the Trustee shall not have sent the notice of such meeting within 20 days after receipt of
such request (and, if applicable, sufficient funds to cover such costs), then the Company or such Holders may determine the time and the place for such meeting and may call such meeting to take any action authorized in Section 9.01, by sending

vote at any meeting of Holders a Person shall (a) be a Holder of one or more Notes on the record date pertaining to such meeting or (b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more Notes on the
record date pertaining to such meeting. The only Persons who shall be entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel and any representatives of the Trustee and its
counsel and any representatives of the Company and its counsel. 
 Section 9.05. Regulations. Notwithstanding any
other provisions of the Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders, in regard to proof of the holding of Notes and of the appointment of proxies, and in regard to the appointment
and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall think fit. 

The Trustee may, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders as provided in Section 9.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the
meeting may be elected by vote of the Holders of a majority in aggregate principal amount of the Notes represented at the meeting and entitled to vote at the meeting. 

  
 31 

 Subject to the proviso immediately succeeding clause (iii) of the definition of
“Outstanding” in the Base Indenture, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented by him or her; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Note challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes
held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 9.02 or Section 9.03 may be adjourned from time
to time by the Holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice. 

Section 9.06. Voting. The vote upon any resolution submitted to any meeting of 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 aggregate 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 aggregate 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 the Indenture or of the Notes. 
 ARTICLE 10 

SUPPLEMENTAL INDENTURES 

Section 10.01. Applicability of Article IX of the Base Indenture. Section 9.1 and Section 9.2 of
the Base Indenture shall not apply to the Notes. Instead, the supplemental indenture provisions set forth in this Article 10 shall, with respect to the Notes, supersede in their entirety Section 9.1 and Section 9.2 of the Base Indenture,
and all references in the Base Indenture to such Sections and amendment and waiver provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to the corresponding Sections of this Article 10 and the
supplemental indenture provisions set forth therein. 

  
 32 

 Section 10.02. Supplemental Indentures Without Consent of Holders. The Company, when
authorized by Board Resolutions 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, omission, defect or inconsistency; 

(b)    to provide for the assumption by a Successor Company of the Company’s obligations under the Indenture and the
Notes, in accordance with the provisions of Article 11 (including pursuant to the last sentence of Section 11.03); 

(c)    to add guarantees with respect to the Notes; 

(d)    to secure the Notes; 

(e)    to add to the covenants or Events of Default of the Company for the benefit of the Holders or surrender any right
or power conferred upon the Company hereunder; 
 (f)    to make any change that does not adversely affect the rights of
any Holder (as determined (which determination shall be binding) by the Board of Directors); 
 (g)    in connection
with any Merger Event, to provide that the Notes are convertible into Reference Property, subject to the provisions of Section 12.02, and make such related changes to the terms of the Notes to the extent expressly required by
Section 12.07; 
 (h)    to comply with any requirement of the Commission in connection with the qualification of
the Indenture under the Trust Indenture Act; 
 (i)    to conform the provisions of the Indenture or the Notes to the
“Description of Notes” section of the Prospectus Supplement; 
 (j)    to provide for a successor trustee
pursuant to the provisions of Article VI of the Base Indenture or to otherwise comply with any requirements of the Indenture; 

(k)    to provide for the issuance of additional Notes, to the extent that the Company deems such supplemental indenture
necessary or advisable in connection with such issuance; provided that no such supplemental indenture shall impair or adversely affect the rights or interests of any Holder (as determined (which determination shall be binding) by the Board of
Directors); provided further that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax or securities law purposes, such additional Notes shall have one or more separate CUSIP
numbers; 
 (l)    to increase the Conversion Rate; 

(m)    to provide for additional rights and benefits for the Holders; or 

  
 33 

 (n)    to provide for the addition of a
co-obligor under the Notes pursuant to the penultimate paragraph of Section 11.02. 
 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, 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, liabilities or immunities under the Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section 10.02 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 10.03. 

Section 10.03. Supplemental Indentures with Consent of Holders. With the consent of the Holders of at least a
majority of the aggregate principal amount of the Notes then Outstanding (including, without limitation, consent, obtained in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by Board Resolutions
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 the Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided, however, that, without the written consent of each Holder of an Outstanding Note affected thereby, no such
supplemental indenture shall: 
 (a)    reduce the amount of Notes whose Holders must consent to an amendment; 

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

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

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

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

(f)    make any Note payable in a currency other than that stated in the Note; 

(g)    make any Note payable at a Place of Payment, other than in the continental United States of America; 

(h)    change the ranking of the Notes; 

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

  
 34 

 (j)    make any change in this Article 10 that requires each Holder’s
consent or in the waiver provisions in Section 6.03 or Section 6.08. 
 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 9.3 of the Base Indenture, 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, liabilities or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. For the
avoidance of doubt, Holders may approve any amendment in accordance with Article 8 hereof or by written consent. 
 Holders do not need
under this Section 10.03 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall
send to the Holders a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders, or any defect in the notice, shall not impair or affect the validity of the supplemental indenture. 

ARTICLE 11 

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 

Section 11.01. Applicability of Article VIII of the Base Indenture. Article VIII of the Base Indenture shall
not apply to the Notes. Instead, the consolidation, merger, sale, conveyance and lease provisions set forth in this Article 11 shall, with respect to the Notes, supersede in their entirety such Article VIII of the Base Indenture, and all references
in the Base Indenture to such Article VIII and Company successor provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 11 and the consolidation, merger, sale, conveyance and lease
provisions set forth in this Article 11. 
 Section 11.02. Company May Consolidate, Etc. on Certain Terms. Subject to the
provisions of Section 11.03, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person, unless: 

(a)    the resulting, surviving or transferee Person (the “Successor Company”), if not the 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 the Indenture; 
 (b)    immediately after giving effect to such
transaction, no Default or Event of Default shall have occurred and be continuing under the Indenture; and 
 (c)    if
the Company is not the Successor Company, the Successor Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel as conclusive evidence, each stating that such consolidation, merger, sale, conveyance,
transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such 

  
 35 

 
transaction, such supplemental indenture, complies with the provisions of this Article 11, and an Opinion of Counsel that any such supplemental indenture is the valid and binding
obligation of the Successor Company, subject to customary exceptions. 
 Notwithstanding anything to the contrary herein, following an
acquisition of 100% of the Common Stock by a Person that is a corporation for U.S. federal income tax purposes in a transaction in which holders of the Common Stock receive as consideration stock of that corporation, the Company may convert into a
limited liability company organized and existing under the laws of the United States of America, any state thereof or the District of Columbia (provided that a co-obligor of the Notes is a corporation
organized or existing under such laws) that is wholly owned by that corporation if the conditions set forth in clauses (a), (b) and (c) above are otherwise satisfied. 

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

Section 11.03. 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 (if not the Company), by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid
interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of the Indenture to be
performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s properties and assets, shall be substituted for, and may exercise every right
and power of, the Company, with the same effect as if it had been named herein as the party of the first part. 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
the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the 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 the Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in
the case of a lease), upon compliance with this Article 11, the Person named as the “Company” in the first paragraph of this Second Supplemental Indenture (or any successor that shall thereafter have become such in the manner prescribed in
this Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and

  
 36 

 
from its obligations under the Indenture and the Notes. 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. 
 ARTICLE 12 

CONVERSION OF NOTES 

Section 12.01. Conversion Privilege. (a) Subject to and upon compliance with the provisions of this Article 12,
each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple of $1,000 principal amount in excess thereof; provided
that the remaining principal amount of such Note after such conversion is $1,000 or an integral multiple of $1,000 in excess thereof) of such Note (i) subject to satisfaction of the conditions described in Section 12.01(b), at any time prior to
the close of business on the Business Day immediately preceding September 1, 2023 under the circumstances and during the periods set forth in Section 12.01(b), and (ii) regardless of the conditions described in Section 12.01(b), on or
after September 1, 2023 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 16.3713 shares of Common Stock (subject to adjustment as
provided in this Article 12, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 12.02, the “Conversion Obligation”). 

(b)    (i) Prior to the close of business on the Business Day immediately preceding September 1, 2023, a Holder may
surrender to the Conversion Agent all or any portion of its Notes for conversion at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the
Trading Price per $1,000 principal amount of Notes, as determined following a written request by a Holder of Notes in accordance with this subsection (b)(i) and the definition of “Trading Price” in Section 2.01(c), 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 on each such Trading Day and the applicable Conversion Rate on each such Trading Day (the “Trading Price Condition”). 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 Second Supplemental Indenture. Any such determination shall be conclusive absent manifest
error. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along
with appropriate contact information for each and the Company shall direct such securities dealers to provide the required information to the Bid Solicitation Agent. The Bid Solicitation Agent (if other than the Company) shall have no obligation to
determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request (or, if the Company is acting as the Bid Solicitation
Agent, the Company shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading
Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the applicable Conversion Rate on such Trading Day, 

  
 37 

 
at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company) in writing to determine, or if the Company is acting as the Bid Solicitation Agent, the Company
shall determine, the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product
of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. If (x) the Company is not acting as the Bid Solicitation Agent, and the Company does not instruct the Bid Solicitation Agent to determine the Trading Price
per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company so instructs the Bid Solicitation Agent to obtain bids 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 when obligated as provided in the preceding sentence, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be
less than 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on each Trading Day of such failure. If the Trading Price Condition has been met, the Company shall so notify the Holders, and the
Trustee and the Conversion Agent (if other than the Trustee) in writing. If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the
Last Reported Sale Price of the Common Stock and the applicable Conversion Rate for such Trading Day, the Company shall so notify the Holders of the Notes, and the Trustee and the Conversion Agent (if other than the Trustee) in writing. 

(ii)    If, prior to the close of business on the Business Day immediately preceding September 1,
2023, the Company elects to: 
 (A)    issue to all or substantially all holders of the Common Stock any
rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of
the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or 

(B)    distribute to all or substantially all holders of the Common Stock the Company’s assets,
securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined (which determination shall be binding) by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the
Common Stock on the Trading Day preceding the date of announcement of 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) in writing at least 80 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has
given such notice, a Holder may surrender all or any portion of its Notes for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the
Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise
convertible at such time. 

  
 38 

 (iii)    If a transaction or event that constitutes a
Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business Day immediately preceding September 1, 2023, regardless of whether a Holder has the right to require the Company to repurchase the Notes
pursuant to Section 13.02, 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 that occurs prior to the close of business on the Business Day
immediately preceding September 1, 2023, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, all or any portion of a Holder’s Notes may be surrendered for conversion at any time from
or after the date that is 80 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Company gives notice of such transaction) until 35 Trading Days after the actual effective date
of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. Subject to the immediately succeeding sentence, the Company shall notify Holders, and the Trustee and the
Conversion Agent (if other than the Trustee) in writing, as promptly as practicable following the date the Company publicly announces such transaction (and in no event less than 80 Scheduled Trading Days prior to the anticipated effective date of
such transaction). However, if the Company does not have knowledge of such transaction at least 80 Scheduled Trading Days prior to the anticipated effective date of such transaction, the Company shall notify Holders, and the Trustee and the
Conversion Agent (if other than the Trustee) in writing, within two Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such
transaction. 
 (iv)    Prior to the close of business on the Business Day immediately preceding
September 1, 2023, a Holder may surrender all or any portion of its Notes for conversion at any time during any calendar quarter commencing after the calendar quarter ending on September 30, 2017 (and only during such calendar quarter), if
the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than
or equal to 130% of the Conversion Price on each applicable Trading Day. 
 Section 12.02. Conversion Procedure; Settlement
Upon Conversion. 
 (a)    Subject to this Section 12.02, Section 12.03(b) and Section 12.07(a),
upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock,
together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 12.02 (“Physical Settlement”) or a combination of cash and shares of Common
Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 12.02 (“Combination Settlement”), at its election, as set forth in this
Section 12.02. 

  
 39 

 (i)    All conversions for which the relevant Conversion Date
occurs on or after September 1, 2023 shall be settled using the same Settlement Method. 

(ii)    Except for any conversions for which the relevant Conversion Date occurs on or after
September 1, 2023, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different
Conversion Dates. 
 (iii)    If, in respect of any Conversion Date (or, in the case of any conversions
for which the relevant Conversion Date occurs on or after September 1, 2023), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or all such
conversions, as the case may be), the Company shall deliver such Settlement Notice to converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) in writing, no later than the close of business on the Trading Day immediately
following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs on or after September 1, 2023, no later than September 1, 2023). If the Company does not elect a Settlement Method
prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement for such conversion (or, in the case of conversions for which the relevant Conversion
Date occurs on or after September 1, 2023, for all such conversions) and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of
Notes shall be equal to $1,000. Each Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000
principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation for a conversion (or, in the case of conversions for which the relevant Conversion Date occurs on or after
September 1, 2023, for all such conversions), but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be
$1,000. For the avoidance of doubt, if the Company does not elect a Settlement Method on or prior to September 1, 2023 for all conversions for which the relevant Conversion Date occurs on or after September 1, 2023, the Company shall be
deemed to have elected Combination Settlement with a Specified Dollar Amount per $1,000 principal amount of Notes equal to $1,000 for all such conversions. 

  
 40 

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

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

(B)    if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash
Settlement, the Company shall pay through the Conversion Agent to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 70
consecutive Trading Days during the related Observation Period; and 
 (C)    if the Company elects (or
is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1,000 principal amount of Notes being converted, a
Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 70 consecutive Trading Days during the related Observation Period. 

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

(b)    Subject to Section 12.02(e), before any Holder of a Note shall be entitled to convert a Note as set forth above,
such Holder shall (i) in the case of a Global Note, comply with the Applicable 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 12.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a
facsimile thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted, (2) surrender such Notes, duly endorsed to the Company or in blank
(and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable
on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 12.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 12 on the Conversion
Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly
withdrawn such Fundamental Change Repurchase Notice in accordance with Section 13.03. 

  
 41 

 If more than one Note shall be surrendered for conversion at one time by the same Holder, the
Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 

(c)    A Note shall be deemed to have been converted immediately prior to the close of business on the date that the
Holder has complied with the requirements set forth in subsection (b) above (the “Conversion Date”). Except as set forth in Section 12.03(b) and Section 12.07(a), the Company shall pay or deliver, as the case may be, the
consideration due in respect of the Conversion Obligation no later than the third Scheduled Trading Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or no later than the third Scheduled Trading Day
immediately following the last Trading Day of the relevant Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to
such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s
Conversion Obligation. 
 (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 residual balance 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 documentary, stamp or similar issue or transfer tax or similar
governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the residual balance Notes issued upon such conversion being different from the name of the Holder of the old Notes
surrendered for such conversion. 
 (e)    If a Holder submits a Note for conversion, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case
the Holder shall pay that tax. The Company or the Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Company receives a sum sufficient to
pay any tax that is due by such Holder in accordance with the immediately preceding sentence. 
 (f)    Except as
provided in Section 12.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 12. 

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

  
 42 

 (h)    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 settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid
interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or
forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are
converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date
notwithstanding the conversion. However, Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds
equal to the amount of interest payable on the Notes so converted; provided that no such payment shall be required (1) for Notes converted after the close of business on the Regular Record Date immediately preceding the Maturity Date and
before the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business
Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Notes. Therefore, for the avoidance of doubt, all
Holders at the close of business on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date regardless of whether their Notes have been converted following such Regular Record
Date. 
 (i)    The Person in whose name any shares of Common Stock shall be issuable upon conversion shall become the
holder of record of such shares as of the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if
the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion. 

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

 Section 12.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes. (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change,
the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A
conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent during the period from, and including, the
Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental
Change but for the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change
Period”). 
 (b)    Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change
pursuant to Section 12.01(b)(iii), the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 12.02; provided,
however, that if, at the Effective Date of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole
Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and
shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation
shall be paid to Holders in cash on the third Scheduled Trading Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than the Trustee) 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 number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by
reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share
of the Common Stock in the Make-Whole Fundamental Change. If all the holders of the Common Stock receive in exchange for their Common Stock 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. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day
immediately preceding the Effective Date of the Make-Whole Fundamental Change. 
 (d)    The Stock Prices set forth in
the column headings of the table in subsection (e) below shall be adjusted as of any date on which the Conversion Rate 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 

  
 44 

 
prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table in
subsection (e) below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 12.04. 

(e)    The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall
be increased per $1,000 principal amount of Notes pursuant to this Section 12.03 for each hypothetical Stock Price and Effective Date set forth below:

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

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

(ii)    if the Stock Price is greater than $200.00 per share (subject to adjustment in the same manner as
the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and 

(iii)    if the Stock Price is less than $46.10 per share (subject to adjustment in the same manner as the
Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate. 

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 21.6918 shares of Common Stock, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 12.04. 
 Section 12.04. 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 (other than in
the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, 

  
 45 

 
in any of the transactions described in this Section 12.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to (i) the applicable
Conversion Rate, multiplied by (ii) the principal amount of Notes held by such Holder, divided by $1,000. 

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

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the
Effective Date of such share split or share combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date, as applicable;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date, as applicable; and
			
	OS1	  	=	  	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 12.04(a) shall become effective immediately after the open of business
on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or
distribution of the type described in this Section 12.04(a) is declared that results in an adjustment under this Section 12.04(a) but is not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of
Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

(b)    If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants
entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices
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: 

 
 

 

  
 46 

 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;
			
	X	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading
Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

 Any increase made under this Section 12.04(b) shall be made successively whenever any such rights, options or
warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the
expiration of such rights, options or warrants, 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 12.04(b) and for the
purpose of Section 12.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share that is less than such average of the Last Reported Sale
Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of 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
(which determination shall be binding) by the Board of Directors. 
 (c)    If the Company distributes shares of its
Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding:
(i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 12.04(a) or Section 12.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to
Section 12.04(d), and (iii) Spin-Offs as to which the 

  
 47 

 
provisions set forth below in this Section 12.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire
Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula: 
  

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
			
	SP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend
Date for such distribution; and
			
	FMV	  	=	  	the fair market value (as determined (which determination shall be binding) by the Board of Directors) of the Distributed Property with respect to each outstanding share of the Common Stock on the
Ex-Dividend Date for such distribution.

 Any increase made under the portion of this Section 12.04(c) above shall become effective immediately after
the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if
such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the
foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed
Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors
determines the “FMV” (as defined above) of any distribution for purposes of this Section 12.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the 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, and including, the Trading Day immediately preceding the Ex-Dividend Date
for such distribution. 
 With respect to an adjustment pursuant to this Section 12.04(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 

  
 48 

 
of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”),
the Conversion Rate shall be increased based on the following formula: 
  
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	FMV0	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of
Last Reported Sale Price as set forth in Section 2.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
			
	MP0	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 The increase to the Conversion Rate under the preceding paragraph shall occur on the last Trading Day of the
Valuation Period; provided that (i) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, the reference to “10” in the preceding
paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such Conversion Date in
determining the Conversion Rate and (ii) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that occurs during the relevant Observation Period for such conversion and
during the Valuation Period, the reference to “10” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date for such Spin-Off and such Trading Day in the Valuation Period in determining the Conversion Rate as of such Trading Day. If the Ex-Dividend Date for such Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” in the preceding paragraph and this
paragraph shall be deemed replaced, for purposes of calculating the applicable Conversion Rate solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the last Trading Day of such Observation Period. 

If any such payment or distribution that constitutes a Spin-Off is declared but not made, and such
payment or distribution has resulted in an adjustment to the Conversion Rate pursuant to the portion of this Section 12.04(c) related to Spin-Offs, the Conversion Rate shall be re-adjusted, effective as of the
date the Board of Directors determines not to make such payment or distribution, to be the Conversion Rate that would then be in effect if such payment or distribution had not been declared. 

  
 49 

 For purposes of this Section 12.04(c) (and subject in all respects to Section 12.11),
rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, 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 12.04(c) (and no adjustment to the Conversion Rate under this Section 12.04(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
12.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Second Supplemental Indenture, are subject to events, upon the occurrence of which such rights, options or
warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and
Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise
by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect
thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 12.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been
redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall
then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of
Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such
rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 

For purposes of Section 12.04(a), Section 12.04(b) and this Section 12.04(c), if any dividend or distribution to which this Section 12.04(c)
is applicable also includes one or both of: 
 (A)    a dividend or distribution of shares of Common Stock to which
Section 12.04(a) is applicable (the “Clause A Distribution”); or 
 (B)    a dividend or distribution
of rights, options or warrants to which Section 12.04(b) is applicable (the “Clause B Distribution”), 
 then, in either case,
(1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 12.04(c) is applicable (the “Clause C Distribution”)
and any Conversion Rate adjustment required by this Section 12.04(c) with respect to such Clause C Distribution shall then be made, 

  
 50 

 
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 12.04(a)
and Section 12.04(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 open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 12.04(a) or “outstanding immediately prior to the open of
business on such Ex-Dividend Date” within the meaning of Section 12.04(b). The adjustments to the Conversion Rate made pursuant to the provisions of this paragraph shall be made without duplication. 

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

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	  	=	  	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	  	=	  	the amount in cash per share the Company distributes to all or substantially all holders of the Common Stock.

 Any increase pursuant to this Section 12.04(d) shall become effective immediately after the open of business
on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines
not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or
greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the
same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the
Ex-Dividend Date for such cash dividend or distribution. 
 (e)    If the
Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the
average of 

  
 51 

 
the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer (such last date, the “Expiration Date”), the Conversion Rate shall be increased based on the following formula: 

 
 

 
 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date;
			
	CR1	  	=	  	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 Expiration Date;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined (which determination shall be binding) 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 Expiration Date (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange
offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
and
			
	SP1	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

 The increase to the Conversion Rate under this Section 12.04(e) shall occur at the close of business on the
10th consecutive Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date; provided that (i) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant
Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date, references in the preceding paragraph to “10” or “10th” shall be deemed replaced with
such lesser number of Trading Days as have elapsed between the Expiration Date and such Conversion Date in determining the applicable Conversion Rate and (ii) in respect of any conversion of Notes for which Cash Settlement or Combination
Settlement is applicable, for any Trading Day that occurs during the relevant Observation Period for such conversion and during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date, references
in this Section 12.04(e) to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as 

  
 52 

 
have elapsed between the Expiration Date and such Trading Day in determining the applicable Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the Expiration
Date is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references in the preceding paragraph to “10” or “10th” and this paragraph shall be
deemed replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading Day of such
Observation Period. 
 (f)    Notwithstanding this Section 12.04 or any other provision of the Indenture or the
Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or
prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 12.02(i) based on an adjusted Conversion Rate for such
Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this Section 12.04, the Conversion Rate adjustment relating to such Ex-Dividend
Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other
event giving rise to such adjustment. 
 (g)    If the application of the formulas set forth in this Section 12.04
would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (other than as a result of a reverse share split or share combination). Except as set forth in this Second Supplemental Indenture, the Company
shall not adjust the Conversion Rate. 
 (h)    In addition to those adjustments required by clauses (a), (b), (c), (d)
and (e) of this Section 12.04, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the
Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors determines (which determination shall be binding) that such increase would be in the Company’s best interest. In addition, to the extent permitted
by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, 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 of Common Stock (or rights to acquire shares of Common Stock) or similar event. 

(i)    Notwithstanding anything to the contrary in this Article 12, the 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 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; 

  
 53 

 (iii)    upon the issuance of any shares of the Common Stock
pursuant to the warrant transactions entered into concurrently with the issuance of the Existing Convertible Notes, the Amazon Warrants or any other 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)    solely for a change in the par value of the Common Stock; 

(v)    for accrued and unpaid interest, if any; or 

(vi)    for guarantees issued in respect of any outstanding securities of the Company. 

(j)    All calculations and other determinations under this Article 12 shall be made by the Company (except as explicitly
otherwise provided herein) and all calculations of the Conversion Rate shall be made to the nearest one-ten thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment to the
Conversion Rate under the Indenture unless the adjustment would result in a change of at least 1% in the then-applicable Conversion Rate. However, the Company shall carry forward any adjustment to the Conversion Rate that is less than 1% of the
then-applicable Conversion Rate, take such carried-forward adjustments into account in any subsequent adjustment, and make such carried-forward adjustments, regardless of whether the aggregate adjustment is less than 1% of the then-effective
Conversion Rate, (i) annually on the anniversary of the date of this Second Supplemental Indenture, (ii) on the Conversion Date for any Notes (in the case of Physical Settlement), (iii) on each Trading Day during any Observation Period
related to any conversion of the Notes (in the case of Cash Settlement or Combination Settlement) and (iv) on the Effective Date of any Fundamental Change or Make-Whole Fundamental Change. 

(k)    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 send
such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Note Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 

(l)    For purposes of this Section 12.04, the number of shares of Common Stock at any time outstanding shall not
include shares of Common Stock held in the treasury of the 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 of Common Stock
issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 

  
 54 

 Section 12.05. Adjustments of Prices. Whenever any provision of the Indenture
requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable, the period for
determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an
adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the
Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 
 Section 12.06. Shares to Be Fully
Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are
presented for conversion (assuming delivery of the maximum number of Additional Shares pursuant to Section 12.03 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that
Physical Settlement were applicable). 
 Section 12.07. Effect of Recapitalizations, Reclassifications and Changes of the Common
Stock. 
 (a)    In the case of: 

(i)    any recapitalization, reclassification or change of the Common Stock (other than changes resulting
from a subdivision or combination), 
 (ii)    any consolidation, merger or combination involving the
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 statutory
share exchange, 
 in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or
assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a
right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the
Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference
Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the

  
 55 

 
case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.02(g) providing for such change in the right to convert each $1,000 principal amount of Notes;
provided, however, that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of
Notes in accordance with Section 12.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 12.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company
would have been required to deliver upon conversion of the Notes in accordance with Section 12.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been
entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 

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 into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of
Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common
Stock receive only cash in such Merger Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of
Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to and during the time periods set forth under Section 12.03), multiplied by the
price paid per share of Common Stock in such Merger Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Scheduled Trading Day immediately following the relevant Conversion Date.
The Company shall notify Holders, and the Trustee and the Conversion Agent (if other than the Trustee) in writing, of such weighted average as soon as practicable after such determination is made. 

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that
shall be as nearly equivalent as is possible to the adjustments provided for in Section 12.04 and Section 12.05. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets
(including cash or any combination thereof) of a Person other than the Company or the successor or purchasing corporation, as the case may be, in 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 the provisions providing for the purchase rights set
forth in Article 13. Following any Merger Event, each reference herein to a share of Common Stock and the Common Stock shall be deemed to refer to a unit of Reference Property and the Reference Property, respectively, subject to the provisions of
such supplemental indenture. 

  
 56 

 (b)    When the Company executes a supplemental indenture pursuant to
subsection (a) of this Section 12.07, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a
unit of Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly send notice thereof to all Holders. The Company shall cause notice
of the execution of such supplemental indenture to be sent to each Holder, at its address appearing on the Note Register provided for in the Indenture, within 20 Business 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 12.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common
Stock, as applicable, as set forth in Section 12.01 and Section 12.02 prior to the effective date of such Merger Event. 

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

Section 12.08. Certain Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes
shall be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(b)    The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes
hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company shall, to the extent then permitted by the rules and
interpretations of the Commission, secure such registration or approval, as the case may be. 
 (c)    The Company
further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company shall list and keep listed, so long as the Common Stock shall be so listed on such exchange or
automated quotation system, any Common Stock issuable upon conversion of the Notes; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the
first conversion of the Notes into Common Stock or a combination of cash and Common Stock in accordance with the provisions of this Second Supplemental Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes
in accordance with the requirements of such automated quotation system or exchange at such time. 
 Section 12.09. Responsibility of
Trustee. The Trustee and any 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 Conversion Agent shall not be accountable with respect to the validity or value 

  
 57 

 
(or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any
Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any 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 12.07(a) relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 12.07(a) or to any adjustment to be made with respect thereto, but, subject to
the provisions of Section 6.3 of the Base Indenture, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate
(which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event
contemplated by Section 12.01(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 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 promptly after the Trustee or the Conversion
Agent (if other than the Trustee) receives a request to convert the Notes under Section 12.01(b). The Company shall promptly respond in writing to a request from the Conversion Agent to the Company to confirm if the condition in Section 12.01(b)(iv)
has been met. 
 Section 12.10. [Reserved]. 

Section 12.11. Stockholder Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes into
Common Stock (or a combination of cash and Common Stock), each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock
issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights
have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all
holders of the Common Stock Distributed Property as provided in Section 12.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

 ARTICLE 13 

REPURCHASE OF NOTES AT OPTION OF
HOLDERS 
 Section 13.01. [Reserved].  

Section 13.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any
time prior to the Maturity Date, 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 thereof that is equal to $1,000 or an integral multiple of
$1,000 in excess thereof, on the 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 (the “Fundamental Change Repurchase
Date”) at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase
Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay on the applicable
Interest Payment Date the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant
to this Article 13. The Fundamental Change Repurchase Date shall be subject to postponement to comply with applicable law. 

(b)    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, the Conversion Agent (in the case of a Conversion Agent other than the Trustee) and the Paying Agent (in the case of a Paying Agent other than the Trustee) in writing, 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. In the case of Physical Notes, such notice
shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the Applicable Procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the
information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in New York City or publish such information on the Company’s website or through such other public medium as the Company 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 13;

 (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 Conversion Rate and any adjustments to the Conversion Rate; 

  
 59 

 (viii)    that the Notes with respect to which a Fundamental
Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture, if applicable; 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 13.02. 
 At the Company’s request, the
Paying Agent 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 Fundamental Change Company Notice shall be prepared by the Company. 

(c)    Repurchases of Notes under this Section 13.02 shall be made, at the option of the Holder thereof, upon: 

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

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

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

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

 (ii)    the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an
integral multiple of $1,000 in excess thereof; and 
 (iii)    that the Notes are to be repurchased by
the Company pursuant to the applicable provisions of the Notes and the Indenture; 
 provided, however, that if the Notes are Global Notes,
the Fundamental Change Repurchase Notice must comply with Applicable Procedures. 

  
 60 

 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 13.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately
preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 13.03. 

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

(e)    Notwithstanding the foregoing, the Company shall not be required to purchase, or to make an offer to purchase, any
Notes upon a Fundamental Change if a third party makes such an offer in the same manner, at the same time, for the same or greater price and otherwise in compliance with the requirements for an offer made by the Company as set forth in this Article
13 and such third party purchases all Notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time, for the same or greater price and otherwise in compliance with the requirements for an offer made by the
Company as set forth in this Article 13. 
 (f)    To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Article 13 relating to the Company’s obligation to repurchase the Notes upon a Fundamental Change, the Company shall comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under such provisions of this Article 13 by virtue of such conflict. 
 Section 13.03.
Withdrawal of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with this
Section 13.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 

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

  
 61 

 (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 in excess thereof; 

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

Section 13.04. Deposit of Fundamental Change Repurchase Price. (a) The Company shall deposit with the 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 10.3 of the Base Indenture (as modified hereby) prior to the Fundamental Change Repurchase Date (or, if the
Company is acting as its own Paying Agent, on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date) an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change
Repurchase Price. Subject to receipt of funds and/or Notes by the Paying Agent appointed by the Company, payment for Notes properly surrendered for repurchase (and not validly withdrawn prior to the close of business on the Business Day immediately
preceding the Fundamental Change Repurchase Date) shall be made on the later of (i) the Fundamental Change Repurchase Date (provided the Holder has satisfied the conditions in Section 13.02) and (ii) the time of book-entry
transfer or the delivery of such Note to the Paying Agent appointed by the Company by the Holder thereof in the manner required by Section 13.02 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 Paying Agent 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 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, with respect to the Notes that have been properly surrendered for repurchase and have
not been validly withdrawn, (i) such Notes shall cease to be Outstanding, (ii) interest shall cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Paying
Agent) and (iii) all other rights of the Holders of such Notes shall terminate (other than the right to receive the Fundamental Change Repurchase Price). 

(c)    Upon surrender of a Physical Note that is to be repurchased in part pursuant to Section 13.02, the Company
shall execute and the Trustee shall authenticate and deliver to the Holder a residual balance Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

 Section 13.05. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In
connection with any repurchase offer, the Company shall, 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 other required schedule under the Exchange Act; 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 13 to be exercised in the time and in the manner
specified in this Article 13. 
 Section 13.06. Paying Agent. For purposes of this Article 13, the Paying Agent may be any
agent, depositary, tender agent, paying agent or other agent appointed by the Company, in each case with an office or agency in the continental United States of America, to accomplish the purposes set forth herein. The Company shall notify Holders,
the Trustee and the Conversion Agent (if other than the Trustee) within one Business Day of any change in the location of the Paying Agent designated for purposes of this Article 13.

ARTICLE 15 

MISCELLANEOUS PROVISIONS 

Section 15.01. Governing Law; Jurisdiction. This Second Supplemental Indenture and the Notes shall be governed by, and construed
in accordance with, the laws of the State of New York. 
 The Company irrevocably and unconditionally waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with the Indenture brought in the courts of the State of New York or the
courts of the United States located in The Borough of Manhattan, New York City, New York and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in
any such court has been brought in an inconvenient forum. 
 Section 15.02. No Security Interest Created. Nothing in the
Indenture or in the Notes, expressed or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction. 

  
 63 

 Section 15.03. Benefits of Supplemental Indenture. Nothing in this Second
Supplemental Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Second
Supplemental Indenture. 
 Section 15.04. Effect of Headings and Table of Contents. The Article and Section headings herein and
the Table of Contents are for convenience only and shall not affect the construction hereof. 
 Section 15.05. Execution in
Counterparts. This Second Supplemental Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. The
exchange of copies of this Second Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Second Supplemental Indenture as to the parties hereto and may be used in lieu
of the original Second Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 

Section 15.06. Separability Clause. In case any provision in this Second Supplemental Indenture or in the Notes shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

Section 15.07. Legal Holidays. In any case where any Interest Payment Date, Fundamental Change Repurchase Date or Maturity Date
shall not be a Business Day or shall be a day on which banking institutions in the Place of Payment are authorized or obligated by law to close or be closed, then (notwithstanding any other provision of the Indenture or of the Notes) any payment to
be made with respect to the Notes need not be made at such Place of Payment on such date, but may be made on the next succeeding day that is both a Business Day and is not a day on which banking institutions in such Place of Payment are authorized
or obligated by law to close or be closed, with the same force and effect as if made on such Interest Payment Date, Fundamental Change Repurchase Date or Maturity Date; provided that no interest shall accrue on the amount then payable for the
period from and after such Interest Payment Date, Fundamental Change Repurchase Date or Maturity Date, as the case may be. Section 1.13 of the Base Indenture shall, with respect to the Notes, be superseded in its entirety by this
Section 15.07, and any reference in the Base Indenture to such Section 1.13 shall, with respect to the Notes, be deemed to refer instead to this Section 15.07. 

Section 15.08. Calculations. The Company shall be responsible for making all calculations called for under the Notes, except where
noted herein. These calculations include, but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, the Daily VWAPs, the Daily Conversion Values, the Daily Settlement Amounts, accrued interest payable on the Notes
and the Conversion Rate of the Notes. The Company shall make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders of Notes. The Company shall provide a schedule of its
calculations to each of the Trustee and the Conversion Agent, and each of the Trustee and Conversion Agent is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee shall
forward the Company’s calculations to any Holder of Notes upon the request of such Holder at the sole cost and expense of the Company. 

  
 64 

 Section 15.09. Conflict With Trust Indenture Act. If any provision hereof limits,
qualifies or conflicts with another provision hereof which is required to be included in this Second Supplemental Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision hereof limits,
qualifies or conflicts with the duties imposed by Section 318(c) of the Trust Indenture Act, such imposed duties shall control. If any provision of this Second Supplemental Indenture limits, qualifies or conflicts with a provision of the Trust
Indenture Act that is required under the Trust Indenture Act to be a part of and govern this Second Supplemental Indenture, such provision of the Trust Indenture Act shall control. If any provision of this Second Supplemental Indenture modifies or
excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Second Supplemental Indenture as such provision of the Trust Indenture Act is so modified or excluded, as
the case may be. 
 Section 15.10. Successors and Assigns. All covenants and agreements in this Second Supplemental Indenture by
the Company shall bind its successors and assigns, whether so expressed or not. 
 Section 15.11. Waiver of Jury Trial. EACH OF
THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS SECOND SUPPLEMENTAL INDENTURE, THE NOTES OR THE
TRANSACTIONS CONTEMPLATED HEREBY. 
 Section 15.12. Official Acts by Successor Corporation. Any act or proceeding by any
provision of the Indenture authorized or required to be done or performed by any board, committee or Officer of the Company shall and may be done and performed with like force and effect by the like board, committee or officer of any corporation or
other entity that shall at the time be the lawful sole successor of the Company.

DIRECTORS 
 Section 16.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the
principal of or accrued and unpaid interest on any Note, nor 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 Second Supplemental Indenture or in
any supplemental indenture hereto or in any Note, nor 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

 [FORM OF REVERSE OF NOTE] 

Atlas Air Worldwide Holdings, Inc. 

1.875% Convertible Senior Note due 2024 

This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.875% Convertible Senior Notes due 2024 (the
“Notes”), limited to the aggregate principal amount of $289,000,000 all issued or to be issued under and pursuant to the Second Supplemental Indenture dated as of May 23, 2017 (the “Second Supplemental
Indenture”), between the Company and Wilmington Trust, National Association (the “Trustee”), which amends and supplements the Indenture dated as of June 3, 2015 between the Company and the Trustee (the “Base
Indenture” and, as amended and supplemented by the Second Supplemental Indenture and from time to time with respect to the Notes, the “Indenture”) to which Indenture and all indentures supplemental thereto reference is
hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount,
subject to certain conditions specified in the Indenture. Capitalized terms used in this Note and not defined in this Note shall have the respective meanings set forth in the Indenture. 

In case certain Events of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by
either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set
forth in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company shall make all payments and deliveries in
respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect
of the Note. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. 

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the
Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures
modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may on
behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the
Fundamental Change Repurchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as
the case may be, herein prescribed. 

  
 A-5 

 The Notes are issuable in registered form without coupons in minimum denominations of $1,000
principal amount and integral multiples of $1,000 in excess 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 of $1,000 in excess thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

 Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the
occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple
of $1,000 in excess thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
