If the purchases by all Participants in an Offering would otherwise cause the aggregate number of Shares to be sold under the Plan to exceed the number specified in this Section 3, the Company shall make to each Participant in that Offering a pro rata allocation in a uniform and nondiscriminatory manner of the remaining number of Shares which may be sold under the Plan. 
4.    Eligibility and Participation. To be eligible to participate in the Plan for a given Purchase Period, an employee must be an Eligible Employee on the first day of such Purchase Period. An Eligible Employee may elect to participate in the Plan by filing an election form with the Company (or its agent) before the Offering Date for a Purchase Period that authorizes regular payroll deductions from Eligible Compensation beginning with the first payday in such Purchase Period and continuing until the Plan is terminated or the Eligible Employee withdraws from the Plan, modifies his or her authorization, or ceases to be an Eligible Employee, as hereinafter provided. 
5.    Amount of Common Stock Each Eligible Employee May Purchase. 
5.1.    Purchase Amounts and Limitations. Subject to the provisions of this Plan, each Participant shall be offered the right to purchase on the Purchase Date the maximum number of whole Shares that can be purchased with the balance in the Participant’s Recordkeeping Account at the per Share price specified in Section 5.2. Notwithstanding the foregoing, no Participant shall be entitled to: 
(a)    the right to purchase Shares under this Plan and all other employee stock purchase plans (within the meaning of Code § 423(b)), if any, of the Company and its Affiliates that accrues at a rate which in the aggregate exceeds $25,000 of Fair Market Value (determined on the Offering Date of a Purchase Period when the right is granted) for each calendar year in which such right is outstanding at any time; or 
3

(b)    purchase Shares in excess of 25,000 Shares per Offering (or such other maximum Share limit as established by the Committee in its sole discretion), with such limit subject to adjustment from time to time as provided in Section 14.1. 
5.2.    Purchase Price. Unless a different purchase price is established by the Committee for an Offering prior to the commencement of the applicable Purchase Period, the purchase price of each Share sold pursuant to this Plan will be the lesser of (i) 85% of the Fair Market Value of such Share on the Offering Date of the applicable Purchase Period, or (ii) 85% of the Fair Market Value of such Share on the Purchase Date (such lesser price, the “Purchase Price”). In no event shall the Purchase Price be less than the lesser of (i) 85% of the Fair Market Value of such Share on the Offering Date of the applicable Purchase Period, or (ii) 85% of the Fair Market Value of such Share on the Purchase Date. 
6.    Method of Participation. 
6.1.    Notice and Date of Grant. The Company shall give notice to each Eligible Employee of the opportunity to purchase Shares pursuant to this Plan and the terms and conditions of such Offering. The Company contemplates that for tax purposes, the Offering Date for a Purchase Period will be considered the date of the grant of the right to purchase such Shares. 
6.2.    Contribution Elections. Each Eligible Employee who desires to participate in the Plan for a Purchase Period shall signify his or her election to do so by completing an election with the Company (or its agent) in a manner approved by the Committee. An Eligible Employee may elect to have any whole percent of Eligible Compensation (that is, 1%, 2%, 3%, etc.) withheld as a payroll deduction, but not exceeding 10% per pay period (or such other maximum percentage as the Committee may establish from time to time prior to the commencement of an Offering). An election to participate in the Plan and to authorize payroll deductions as described herein must be made prior to the Offering Date of a Purchase Period in accordance with the rules set by the Committee for the Purchase Period, and shall be effective beginning with the first payday in the Purchase Period immediately following the filing of such election. Any election submitted shall remain in effect until the Plan is terminated or such Participant withdraws from the Plan, modifies his or her authorization, or ceases to be an Eligible Employee, as hereinafter provided. 
6.3    Additional Contributions. If specifically provided by the Committee in connection with an Offering (including for purposes of complying with applicable local law), in addition to or instead of making contributions by payroll deductions, a Participant may make additional contributions to his or her Recordkeeping Account through the payment by cash or check prior to a Purchase Date. A Participant may make such additional contributions into his or her Recordkeeping Account only if the Participant has not already had the maximum permitted amount withheld during the Offering through payroll deductions, subject to the limitations set forth in Section 5.1. 
6.4.    Offering Terms and Conditions. Each Offering shall consist of a single Purchase Period and shall be in such form and shall contain such terms and conditions as the Committee shall deem 
4

appropriate, consistent with the terms of the Plan. The Committee may provide for separate Offerings for different Designated Affiliates, and the terms and conditions of the separate Offerings, including the applicable Purchase Period, need not be consistent. Any Offering shall comply with the requirement of Code § 423 that all Participants shall have the same rights and privileges for such Offering. The terms and conditions of any Offering shall be incorporated by reference into the Plan and treated as part of the Plan. 
7.    Recordkeeping Accounts. 
7.1.    Crediting Payroll Deduction Contributions. The Company (or its agent) shall maintain a Recordkeeping Account for each Participant. Payroll deductions pursuant to Section 6 will be credited to such Recordkeeping Accounts on or within a reasonable amount of time following each payday. 

7.2.    No Interest Payable. No interest will be credited to a Participant’s Recordkeeping Account (unless required under local law). 
7.3.    No Segregation of Accounts. The Recordkeeping Account is established solely for accounting purposes, and all amounts credited to the Recordkeeping Account will remain part of the general assets of the Company and need not be segregated from other corporate funds (unless required under local law). 
7.4.    Additional Contributions. A Participant may not make any separate cash payment into a Recordkeeping Account, except as may be permitted in accordance with Section 6.3, and any such additional contributions will be credited to the Recordkeeping Accounts within a reasonable amount of time following receipt by the Company. 
8.    Right to Adjust Participation; Withdrawals from Recordkeeping Account. 
8.1.    Withdrawal from Plan. A Participant may at any time withdraw from the Plan by complying with the rules set by the Committee. If a Participant withdraws from the Plan, the Company will pay to the Participant in cash the entire balance in such Participant’s Recordkeeping Account and no further deductions will be made from the Participant’s Eligible Compensation during such Purchase Period. A Participant who withdraws from the Plan will not be eligible to reenter the Plan until the next succeeding Purchase Period, and any such reentry shall be through the enrollment process described in Section 6.2. 
8.2.    Adjusting Level of Participation. A Participant may adjust his or her rate of payroll deduction contributions to the Plan as follows: 
(a)    A Participant may, by written notice during an Enrollment Period, direct the Company to increase or decrease his or her rate of payroll deduction contributions, with such change to be effective as of the first day of the next Purchase Period. 
5

(b)    A Participant may, by written notice that complies with the rules set by the Committee, direct the Company to decrease his or her rate of payroll deduction contributions during a Purchase Period to 0%, which shall be considered a suspension of contributions and shall become effective as soon as reasonably practicable. Any Participant who has decreased his or her rate of payroll deductions to 0% and does not increase such rate of payroll deductions from 0% to at least 1% in accordance with Section 8.2(a) during the next Enrollment Period will be withdrawn from the Plan effective as of the first day of that next Purchase Period. 
8.3.    Submission of Notices. Notification of a Participant’s election to withdraw from the Plan as provided in Section 8.1 or to change his or her rate of payroll deductions as provided in Section 8.2 shall be made by completing an updated election or notice with the Company (or its agent) in a manner approved by the Committee. The Committee may promulgate rules regarding the time and manner for submitting any such updated election or notice, which may include a requirement that the election or notice be on file for a reasonable period before it will be effective. 
8.4.    Adjustments by the Company. To the extent necessary to comply with Code § 423(b)(8) or Section 5.1, a Participant’s payroll deduction contributions to the Plan may be decreased by the Company to 0% at any time during a Purchase Period. 
9.    Termination of Employment. 
9.1.    Refund of Recordkeeping Account. If the employment of a Participant is terminated for any reason, including death, disability, or retirement, the entire balance in the Participant’s Recordkeeping Account will be refunded in cash to the Participant within 30 days after the date of termination of employment. For purposes of the Plan, a Participant will not be deemed to have terminated employment while the Participant is on sick leave, military leave or other leave of absence approved by the Company. Where the period of leave exceeds 90 days and the Participant’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship shall be deemed to have terminated on the ninety-first day of such leave. Unless determined otherwise by the Committee in a manner that is permitted by, and in compliance with Code § 423, a Participant whose employment transfers between entities through a termination with an immediate rehire (with no break in service) by the Company or a Designated Affiliate shall not be treated as a termination under the Plan. 

9.2.    Designation of Beneficiary. If permitted by the Committee, a Participant may file a beneficiary designation for who is to receive the Participant’s Recordkeeping Account or Share subaccount, if any, following the death of a Participant. If no beneficiary is named, the beneficiary shall be the Participant’s spouse, or if none, the Participant’s estate. All beneficiary designations will be in such form and manner as the Committee may designate from time to time. 
6

10.    Purchase of Shares. 
10.1.    Number of Shares Purchased. As of each Purchase Date, the balance in each Participant’s Recordkeeping Account will be used to purchase the maximum number of whole Shares (subject to the limitations of Section 5.1) at the Purchase Price determined in accordance with Section 5.2, unless the Participant has filed an appropriate form with the Company in advance of that date to withdraw from the Plan in accordance with Section 8.1. Any amount remaining in a Participant’s Recordkeeping Account that represents the Purchase Price for any fractional share will be carried over in the Participant’s Recordkeeping Account to the next Purchase Period. Any amount remaining in a Participant’s Recordkeeping Account that represents the Purchase Price for any whole Shares that could not be purchased by reason of the limitations of Section 5.1 or under the circumstances described in Section 3 will be refunded to the Participant. 
10.2.    Conversion of Foreign Currency. In circumstances where payroll deductions have been taken from a Participant’s Eligible Compensation in a currency other than United States dollars, Shares shall be purchased by converting the balance in the Participant’s Recordkeeping Account to United States dollars at the exchange rate in effect for payroll purposes for the month in which the Purchase Date occurs as determined by the Company’s finance department or at such other exchange rate determined by the Committee or its delegate for this purpose, and such dollar amount shall be used to purchase Shares as of the Purchase Date. 
10.3.    Crediting of Shares. Promptly after the end of each Purchase Period, the number of Shares purchased by all Participants as of the applicable Purchase Date shall be issued and delivered to an agent selected by the Company. Delivery of the shares to the agent shall be effected by an appropriate book-entry in the stock register maintained by the Company’s transfer agent or delivery of a certificate. The agent will hold the Shares for the benefit of all Participants who have purchased Shares and will maintain a Share subaccount for each Participant reflecting the number of Shares credited to each Participant. Each Participant will be entitled to direct the voting by the agent of all Shares credited to such Participant’s Share subaccount, and the agent may reinvest any dividends paid on Shares credited to a Participant’s Share subaccount in additional Shares in accordance with such rules as the Committee may prescribe. Each Participant may also direct the agent to sell any or all of the Shares credited to the Participant’s Share subaccount and distribute the net proceeds of such sale to the Participant. 
10.4    Withdrawal of Shares from Share Subaccount. Except for sales through the agent as provided in Section 10.3, a Participant may not withdraw Shares or otherwise transfer Shares from the Participant’s Share subaccount. 
11.    Rights as a Shareholder. A Participant shall not be entitled to any of the rights or privileges of a shareholder of the Company with respect to Shares offered for purchase under the Plan, including the right to vote or direct the voting or to receive any dividends that may be declared by the Company, until (i) the Participant actually has paid the Purchase Price for such Shares and (ii) such Shares have been issued and delivered, as provided in Section 10.3. 
7

12.    Rights Not Transferable. A Participant’s rights under this Plan are exercisable only by the Participant during his or her lifetime, and may not be sold, pledged, assigned, transferred or disposed of in any manner other than by will or the laws of descent and distribution. Any attempt to sell, pledge, assign, transfer or dispose of the same shall be void and without effect. The amounts credited to a Recordkeeping Account may not be sold, pledged, assigned, transferred or disposed of in any way, and any attempted sale, pledge, assignment, transfer or other disposition of such amounts will be void and without effect. 

13.    Administration of the Plan. 
13.1.    Authority of the Committee. This Plan shall be administered by the Committee. Subject to the express provisions of the Plan and applicable law, and in addition to other express powers and authorizations conferred on the Committee by the Plan, the Committee shall have full power and authority to: 
(a)    Determine when each Purchase Period under this Plan shall occur, and the terms and conditions of each related Offering (which need not be identical); 
(b)    Designate from time to time which Affiliates of the Company shall be eligible to participate in the Plan; 
(c)    Construe and interpret the Plan and establish, amend and revoke rules, regulations and procedures for the administration of the Plan. The Committee may, in the exercise of this power, correct any defect, omission or inconsistency in the Plan, in such manner and to the extent it may deem necessary, desirable or appropriate to make the Plan fully effective; 
(d)    Exercise such powers and perform such acts as the Committee may deem necessary, desirable or appropriate to promote the best interests of the Company and its Designated Affiliates and to carry out the intent that the Offerings made under the Plan are treated as qualifying under Code § 423(b); 
(e)    As more fully described in Section 18, to adopt such rules, procedures and sub-plans as may be necessary, desirable or appropriate to permit participation in the Plan by employees who are foreign nationals or employed outside the United States by a non-U.S. Designated Affiliate, and to achieve tax, securities law and other compliance objectives in particular locations outside the United States; and 
(f)    Adopt and amend, as the Committee deems appropriate, a Plan rule specifying that Shares purchased by a Participant during a Purchase Period may not be sold by the Participant for a specified period of time after the Purchase Date on which the Shares were purchased by the Participant, and establish such procedures as the Committee may deem necessary to implement such rule. 
8

13.2.    Interpretations and Decisions by the Committee. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive, and binding upon all persons, including the Company, any Affiliate, any Participant and any Eligible Employee. 
13.3.    Delegation by the Committee. Subject to the terms of the Plan and applicable law, the Committee may delegate ministerial duties associated with the administration of the Plan to such of the Company’s officers, employees or agents as the Committee may determine. 
13.4.    Indemnification. No member of the Board or Committee shall be liable for any action taken or determination made in good faith with respect to the Plan. In addition to such other rights of indemnification as they may have as members of the Board or officers or employees of the Company or a Designated Affiliate, members of the Board and Committee and any officers or employees of the Company or Designated Affiliate to whom authority to act for the Committee is delegated shall be indemnified by the Company from and against any and all liabilities, costs and expenses incurred by such persons as a result of any act or omission to act in connection with the performance of such person’s duties, responsibilities and obligations under the Plan if such person has acted in good faith and in a manner that he or she reasonably believes to be in, or not opposed to, the best interests of the Company. 
14.    Changes in Capitalization and Corporate Transactions. 
14.1.    Adjustments. In the event of any change in the Common Stock of the Company by reason of a stock dividend, stock split, reverse stock split, corporate separation, recapitalization, merger, consolidation, combination, exchange of shares and the like, the Committee shall make such equitable adjustments as it deems appropriate in the aggregate number and class of Shares or other securities available under this Plan, the Share limitation referred to in Section 5.1(b) of the Plan, and the number, class and Purchase Price of Shares or other securities subject to purchase under any pending Offering. 
 
14.2.    Corporate Transactions. In the event of a Corporate Transaction, each right to acquire Shares on any Purchase Date that is scheduled to occur after the date of the consummation of the Corporate Transaction may be continued or assumed or an equivalent right may be substituted by the surviving or successor corporation or a parent or subsidiary of such corporation. If such surviving or successor corporation or parent or subsidiary thereof refuses to continue, assume or substitute for such outstanding rights, then the Board may, in its discretion, either terminate the Plan or shorten the Purchase Period then in progress by setting a new Purchase Date for a specified date before the date of the consummation of the Corporate Transaction. Each Participant shall be notified in writing, prior to any new Purchase Date, that the Purchase Date for the existing Offering has been changed to the new Purchase Date and that the Participant’s right to acquire Shares will be exercised automatically on the new Purchase Date unless prior to such date the Participant’s employment has been terminated 
9

or the Participant has withdrawn from the Plan. In the event of a dissolution or liquidation of the Company, any Offering and Purchase Period then in progress will terminate immediately prior to the consummation of such action, unless otherwise provided by the Board. 
15.    Amendment or Suspension of Plan. The Committee, in its sole discretion, may at any time suspend this Plan or amend it in any respect, but no such amendment may, without shareholder approval, increase the number of shares reserved under this Plan, or effect any other change in the Plan that would require shareholder approval under applicable law or regulations or the rules of any securities exchange on which the Shares may then be listed, or to maintain compliance with Code § 423. No such amendment or suspension shall adversely affect the rights of Participants pursuant to Shares previously acquired under the Plan. During any suspension of the Plan, no new Offering or Purchase Period shall begin and no Eligible Employee shall be offered any new right to purchase Shares under the Plan or any opportunity to elect to participate in the Plan, and any existing payroll deduction authorizations shall be suspended, but any such right to purchase Shares previously granted for a Purchase Period that began prior to the Plan suspension shall remain subject to the other provisions of this Plan and the discretion of the Board and the Committee with respect thereto. 
16.    Effective Date and Term of Plan. The Plan will become effective on the date it is approved by the shareholders of the Company, which approval must be within 12 months of the date the Plan is adopted by the Board. The Plan and all rights of Participants hereunder shall terminate (i) at any time, at the discretion of the Committee, or (ii) upon the completion of any Offering under which the limitation on the total number of Shares to be issued during the entire term of the Plan, as determined in accordance with Section 3, has been reached. Except as otherwise determined by the Board, upon termination of this Plan, the Company shall pay to each Participant cash in an amount equal to the entire remaining balance in such Participant’s Recordkeeping Account. 
17.    Governmental Regulations and Listing. All rights granted or to be granted to Eligible Employees under this Plan are expressly subject to all applicable laws and regulations and to the approval of all governmental authorities required in connection with the authorization, issuance, sale or transfer of the Shares reserved for this Plan, including, without limitation, there being a current registration statement of the Company under the Securities Act of 1933, as amended, covering the Shares purchasable on the Purchase Date applicable to such Shares. If applicable, all such rights hereunder are also similarly subject to effectiveness of an appropriate listing application to a national securities exchange covering the Shares issuable under the Plan upon official notice of issuance. 
18.    Rules for Foreign Jurisdictions. The Committee may adopt rules, procedures or subplans relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures. Without limiting the generality of the foregoing, the Committee is specifically authorized to adopt rules and procedures regarding handling of payroll deductions, payment of interest, conversion of local currency, payroll tax, the definition of Eligible Compensation, withholding procedures and handling of stock certificates that vary with local requirements. 
10

19.    Miscellaneous. 
19.1.    Effect on Employment Status. This Plan shall not be deemed to constitute a contract of employment between the Company or any Designated Affiliate and any Participant, nor shall it interfere with the right of the Company (or any Affiliate) to terminate the employment of any Participant and treat him or her without regard to the effect that such treatment might have upon him or her under this Plan. 
19.2.    Governing Law. This Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the State of Delaware. 

19.3.    Electronic Documentation and Signatures. Any reference in the Plan to election or enrollment forms, notices, authorizations or any other document to be provided in writing shall include the provision of any such form, notice, authorization or document by electronic means, including through the Company’s intranet or with the Company’s agent, and any reference in the Plan to the signing of any document shall include the authentication of any such document provided in electronic form, in each case in accordance with procedures established by the Committee. 
19.4.    Book-Entry and Electronic Transfer of Shares. Any reference in this Plan to the issuance or transfer of a stock certificate evidencing Shares shall be deemed to include, in the Committee’s discretion, the issuance or transfer of such Shares in book-entry or electronic form. Uncertificated Shares shall be deemed delivered for all purposes of this Plan when the Company or its agent shall have provided to the recipient of the Shares a notice of issuance or transfer by electronic mail (with proof of receipt) or by United States mail, and have recorded the issuance or transfer in its records. 
19.5.    Registration of Share Accounts and Certificates. Any Share account contemplated by Section 10.3 and certificate to be issued to a Participant shall be registered in the name of the Participant, or jointly in the name of the Participant and another person, as the Participant may direct on an appropriate form filed with the Company or the agent. 
19.6.    Code § 409A. The Plan is exempt from the application of Code § 409A and any ambiguities herein will be interpreted to so be exempt from Code § 409A. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Committee determines that an option granted under the Plan may be subject to Code § 409A or that any provision in the Plan would cause an option under the Plan to be subject to Code § 409A, the Committee may amend the terms of the Plan and/or of an outstanding Offering under the Plan, or take such other action as the Committee determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Code § 409A, but only to the extent any such amendments or actions by the Committee would not violate Code § 409A. Notwithstanding the foregoing, the Company and the Committee shall have no liability to a Participant or any other party if the option to purchase Shares under the Plan that is intended to be exempt from or compliant with Code § 409A is not exempt or compliant or for any action taken by the Committee with respect thereto. The Company 
11

makes no representations that the option to purchase Shares under the Plan is compliant with Code § 409A. 
19.7.    Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability shall not affect the remaining parts of the Plan and the Plan shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.

on such record date, and no other Holders, shall be entitled to take the relevant action with respect to the Corporate Units, the Treasury Units or the Cash Settled Units, as the case may be, whether or not such Holders remain Holders after such
record date; provided that no such action shall be effective hereunder unless taken prior to or on the applicable Expiration Date by Holders of the requisite number of Outstanding Units on such record date. Nothing contained in this paragraph
shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by
any Person be cancelled and be of no effect), and nothing contained in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite number of Outstanding Units on the date such action is taken. Promptly after
any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Purchase Contract Agent in writing and
to each Holder in the manner set forth in Section 1.06. 
 With respect to any record date set pursuant to this
Section 1.04(e), the Company may designate any date as the “Expiration Date” and from time to time may change the Expiration Date to any later day; provided that no such change shall be effective
unless notice of the proposed new Expiration Date is given to the Purchase Contract Agent in writing, and to each Holder in the manner set forth in Section 1.06, prior to or on the existing Expiration Date. If an Expiration
Date is not designated with respect to any record date set pursuant to this Section 1.04, the Company shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect
thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

the Agent in a timely manner, and (b) such originally executed instructions or directions shall be signed by an authorized officer (in the case of an instruction or direction from the Company) or an authorized representative of the party
providing such instructions or directions (in all other cases). If the party elects to give the Agent e-mail or facsimile instructions (or instructions by a similar electronic method) and the Agent in its
discretion elects to act upon such instructions or directions, the Agent’s understanding of such instructions or directions, vis a vis such party, shall be deemed controlling. The Agent shall not be liable, vis a vis such party, for any losses,
costs or expenses arising directly or indirectly from the Agent’s reliance upon and compliance with such instructions or directions notwithstanding whether such instructions or directions conflict or are inconsistent with a subsequent written
instruction or direction or the subsequent written instruction or direction is never received. Each of the Agents shall have no duty or obligation to verify or confirm that the person who sent such instructions or directions is, in fact, a person
authorized to give instructions or directions on behalf of the Company; and each such Agent shall have no liability for any losses, liabilities, costs or expenses incurred or sustained by the Company as a result of such reliance upon or compliance
with such notices, instructions, directions or other communications. The Company agrees to assume all risks arising out of the use of such electronic methods to submit notices, instructions, directions or other communications to the Agents,
including without limitation the risk of any such entity acting on unauthorized instructions, and the risk of interception and misuse by third parties. The Company shall use all reasonable efforts to ensure that any such notices, instructions,
directions or other communications transmitted to the Agents pursuant to this Agreement are complete and correct. Any such notices, instructions, directions or other communications shall be conclusively deemed to be valid instructions from the
Company to the Agents, as the case may be, for the purposes of this Agreement.

Facsimile, documents executed, scanned and transmitted electronically and electronic signatures, including those created or transmitted through a software
platform or application, shall be deemed original signatures for purposes of this Agreement and all other related documents and all matters and agreements related thereto, with such facsimile, scanned and electronic signatures having the same legal
effect as original signatures. The parties agree that this Agreement or any other related document or any instrument, agreement or document necessary for the consummation of the transactions contemplated by this Agreement or the other related
documents or related hereto or thereto (including, without limitation, addendums, amendments, notices, instructions, communications with respect to the delivery of securities or the wire transfer of funds or other communications) (“Executed
Documentation”) may be accepted, executed or agreed to through the use of an electronic signature in accordance with applicable laws, rules and regulations in effect from time to time applicable to the effectiveness and
enforceability of electronic signatures. Any Executed Documentation accepted, executed or agreed to in conformity with such laws, rules and regulations will be binding on all parties hereto to the same extent as if it were physically executed
and each party hereby consents to the use of any third party electronic signature capture service providers as may be reasonably chosen by a signatory hereto or thereto. When the Purchase Contract Agent, the Collateral Agent, the Custodial
Agent and the Securities Intermediary acts on any Executed Documentation sent by electronic transmission, the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary will not be responsible or liable for
any losses, costs or expenses arising directly or indirectly from its reliance upon and compliance with such Executed Documentation, notwithstanding that such Executed Documentation (a) may not be an authorized or authentic communication of the
party involved or in the form such party sent or intended to send (whether due to fraud, distortion or otherwise) or (b) may conflict with, or be inconsistent with, a subsequent written instruction or communication; it being understood and
agreed that the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary shall conclusively presume that Executed Documentation that purports to have been sent by an authorized officer of a Person has been
sent by an authorized officer of such Person. The party providing Executed Documentation through electronic transmission or otherwise with electronic signatures agrees to assume all risks arising out of such electronic methods, including, without
limitation, the risk of the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary acting on unauthorized instructions and the risk of interception and misuse by third parties.

 Section 1.06. Notice to Holders; Waiver. Where this Agreement provides

not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed
to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Purchase Contract Agent, but such filing shall not be a condition precedent to the validity of any action taken
in reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to
give such notice by mail, then such notification as shall be made with the approval of the Purchase Contract Agent shall constitute a sufficient notification for every purpose hereunder. 

Notwithstanding the foregoing or any other provision of this Agreement to the contrary, whenever notice is required to be given with respect to a Unit
represented by a Global Certificate, such notice shall be sufficiently given if given to the Depositary for such Global Certificate (or its designee) pursuant to customary procedures of such Depositary.

PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, RELATING TO OR IN CONNECTION WITH THIS AGREEMENT, THE UNITS, THE PURCHASE CONTRACTS OR THE TRANSACTIONS

Section 3.13(a), Section 3.14(a), Section 3.15(a) or Section 8.05. 

The Certificates shall be issuable only in registered form (which, for the avoidance of doubt, in the case of Global Certificates, shall be registered in the
name of the Depositary or its nominee) and only in denominations of a single Corporate Unit, Treasury Unit or Cash Settled Unit and any integral multiple thereof.

 Section 3.02. Rights and Obligations Evidenced by the Certificates. Each
Corporate Units Certificate shall evidence the number of Corporate Units specified therein, with each such Corporate Unit representing (1) the ownership by the Holder thereof of the Pledged Applicable Ownership Interests in Mandatory
Convertible Preferred Stock or the Pledged Applicable Ownership Interests in the Treasury Portfolio, as the case may be, in respect of such Holder’s Corporate Unit and (2) the rights and obligations of the Holder thereof and the Company
under one Purchase Contract. The Purchase Contract Agent is hereby authorized, as attorney-in-fact for, and on behalf of, the Holder of each Corporate Unit, to pledge,
pursuant to Article 11 hereof, the Applicable Ownership Interest in Mandatory Convertible Preferred Stock, or the Applicable Ownership Interest in the Treasury Portfolio, forming a part of such Corporate Unit to the
Collateral Agent, for the benefit of the Company, and to grant to the Collateral Agent, as agent of and for the benefit of the Company, a security interest in the right, title and interest of such Holder in such Applicable Ownership Interest in
Mandatory Convertible Preferred Stock or such Applicable Ownership Interest in the Treasury Portfolio to secure the obligation of the Holder under each Purchase Contract to purchase shares of Common Stock. To effect such Pledge and grant such
security interest, the Transfer Agent, has, on the date hereof, delivered to the Purchase Contract Agent, on behalf of the Holders of Corporate Units, the Applicable Ownership Interests in Mandatory Convertible Preferred Stock. 

Upon the formation of a Treasury Unit pursuant to Section 3.12(a), each Treasury Units Certificate shall evidence the number of
Treasury Units specified therein, with each such Treasury Unit representing (1) the ownership by the Holder thereof of a 1/10 undivided beneficial ownership interest in one Treasury Security, subject to the Pledge of such interest by such
Holder pursuant to this Agreement, and (2) the rights and obligations of the Holder thereof and the Company under one Purchase Contract. The Purchase Contract Agent is hereby authorized, as attorney-in-fact for, and on behalf of, the Holder of each Treasury Unit, to pledge, pursuant to Article 11 hereof, such Holder’s interest in the Treasury Security forming a
part of such Treasury Unit to the Collateral Agent, as agent of and for the benefit of the Company, and to grant to the Collateral Agent, for the benefit of the Company, a security interest in the right, title and interest of such Holder in such
Treasury Security to secure the obligation of the Holder under each Purchase Contract to purchase shares of Common Stock. 
 Upon the formation of a Cash
Settled Unit pursuant to Section 3.13(a), each Cash Settled Units Certificate shall evidence the number of Cash Settled Units specified therein, with each such Cash Settled Unit representing (1) the ownership by the
Holder thereof of $100 Cash, subject to the Pledge of such Cash by such Holder pursuant to this Agreement, and (2) the rights and obligations of the Holder thereof and the Company under one Purchase Contract. The Purchase Contract Agent is
hereby authorized, as attorney-in-fact for, and on behalf of, the Holder of each Cash Settled Unit, to pledge, pursuant to Article 11 hereof,
such Holder’s Cash forming a part of such Cash Settled Unit to the Collateral Agent, as agent of and for the benefit of the Company, and to grant to the Collateral Agent, for the benefit of the Company, a security interest in the right, title
and interest of such Holder in such Cash to secure the obligation of the Holder under each Purchase Contract to purchase shares of Common Stock. 

  
 29 

 The Purchase Contracts shall not, prior to the settlement thereof, entitle the Holder of a Unit to any of
the rights of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or distributions or to consent or to receive notice as a shareholder in respect of the meetings of
shareholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as a shareholder of the Company. 

Section 3.03. Execution, Authentication; Delivery and Dating. Subject to the provisions of
Section 3.12(a), Section 3.13(a), Section 3.14(a) and Section 3.15(a) hereof, upon the execution and delivery of this Agreement, and at any time
and from time to time thereafter, the Company may deliver Certificates executed by the Company to the Purchase Contract Agent for authentication, execution on behalf of the Holders and delivery, together with its Issuer Order for authentication,
execution on behalf of the Holders as their attorney-in-fact and delivery, together with its Issuer Order for authentication, of such Certificates, and the Purchase
Contract Agent in accordance with such Issuer Order shall authenticate, execute on behalf of the Holders as their attorney-in-fact and deliver such Certificates. 

The Certificates shall be executed on behalf of the Company by its Chief Executive Officer, its President, its Chief Financial Officer, any one of its Vice
Presidents, or its Treasurer or one of its Assistant Treasurers. The signature of any of these officers on the Certificates may be manual, electronic or facsimile. 

Certificates bearing the manual, electronic or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the
Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. 

No Purchase Contract evidenced by a Certificate shall be valid until such Certificate has been executed on behalf of the Holder by the manual or electronic
signature of an authorized signatory of the Purchase Contract Agent, as such Holder’s attorney-in-fact. Such signature by an authorized signatory of the Purchase
Contract Agent shall be conclusive evidence that the Holder of such Certificate has entered into the Purchase Contracts evidenced by such Certificate. 

Each Certificate shall be dated the date of its authentication. 

No Certificate shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose unless there appears on such Certificate a
certificate of authentication substantially in the form provided for herein executed by an authorized officer of the Purchase Contract Agent by manual or electronic signature, and such certificate of authentication upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. 
 Section 3.04.
Temporary Certificates. Pending the preparation of definitive Certificates, the Company may execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall, upon receipt of an Issuer Order, authenticate,
execute on behalf of the Holders as their attorney-in-fact, and deliver, in lieu of such definitive Certificates, temporary Certificates which are in substantially the
form set forth in Exhibit A, Exhibit B or Exhibit C 

  
 30 

 
hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be
required by the rules of any securities exchange on which the Corporate Units, Treasury Units or Cash Settled Units, as the case may be, are listed (if any), or as may, consistently herewith, be determined by the officers of the Company executing
such Certificates, as evidenced by their execution of the Certificates. 
 If temporary Certificates are issued, the Company will cause definitive
Certificates to be prepared without unreasonable delay. After the preparation of definitive Certificates, the temporary Certificates shall be exchangeable for definitive Certificates upon surrender of the temporary Certificates at the Corporate
Trust Office, at the expense of the Company and without charge to the Holder. Upon surrender for cancellation of any one or more temporary Certificates, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract
Agent shall, upon receipt of an Issuer Order, authenticate, execute on behalf of the Holder as their attorney-in-fact, and deliver in exchange therefor, one or more
definitive Certificates of like tenor and denominations and evidencing a like number of Units as the temporary Certificate or Certificates so surrendered. Until so exchanged, the temporary Certificates shall in all respects evidence the same
benefits and the same obligations with respect to the Units evidenced thereby as definitive Certificates. 
 Section 3.05.
Registration; Registration of Transfer and Exchange. The Purchase Contract Agent shall keep at the Corporate Trust Office a register (the “Security Register”) in which, subject to such reasonable regulations as are
then customary and standard, the Purchase Contract Agent shall provide for the registration of Certificates and of transfers of Certificates (the Purchase Contract Agent, in such capacity, the “Security Registrar”). The Security
Registrar shall record separately the registration and transfer of the Certificates evidencing Corporate Units, Treasury Units and Cash Settled Units. 

Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office, the Company shall execute and deliver to the Purchase Contract
Agent in its capacity as transfer agent, and the Purchase Contract Agent shall, upon receipt of an Issuer Order, authenticate, execute on behalf of the designated transferee or transferees, and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of any authorized denominations, like tenor, and evidencing a like number of Corporate Units, Treasury Units or Cash Settled Units, as the case may be. 

At the option of the Holder and upon written notice to the Company and the Purchase Contract Agent, Certificates may be exchanged for other Certificates, of
any authorized denominations and evidencing a like number of Corporate Units, Treasury Units or Cash Settled Units, as the case may be, upon surrender of the Certificates to be exchanged at the Corporate Trust Office. Whenever any Certificates are
so surrendered for exchange, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall, upon receipt of an Issuer Order, authenticate, execute on behalf of the Holder as their attorney-in-fact, and deliver to the Holders the Certificates which the Holder making the exchange is entitled to receive. 

  
 31 

 All Certificates issued upon any registration of transfer or exchange of a Certificate shall evidence the
ownership of the same number of Corporate Units, Treasury Units or Cash Settled Units, as the case may be, and be entitled to the same benefits and subject to the same obligations under this Agreement as the Corporate Units, Treasury Units or Cash
Settled Units, as the case may be, evidenced by the Certificate surrendered upon such registration of transfer or exchange. 
 Every Certificate presented
or surrendered for registration of transfer or exchange shall (if so required by the Purchase Contract Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Purchase Contract Agent
duly executed by the Holder thereof or its attorney duly authorized in writing. 
 No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company and the Purchase Contract Agent may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or
exchange of Certificates and any other fees and expenses incurred by the Company or the Purchase Contract Agent (including, without limitation, the fees of expenses of their respective counsel), other than any exchanges pursuant to
Section 3.04, Section 3.06 and Section 8.05 not involving any transfer. 

Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall
not be obligated to authenticate, execute on behalf of the Holder as their attorney-in-fact and deliver any Certificate in exchange for any other Certificate presented
or surrendered for registration of transfer or for exchange on or after the Business Day immediately preceding the earliest to occur of any Early Settlement Date with respect to such Certificate, any Fundamental Change Early Settlement Date with
respect to such Certificate, the Purchase Contract Settlement Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate
registration or transfer instructions from such Holder, the Purchase Contract Agent shall: 
 (a) if the Purchase Contract Settlement Date,
an Early Settlement Date or a Fundamental Change Early Settlement Date with respect to such other Certificate (or portion thereof) has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the
Units evidenced by such other Certificate (or portion thereof) on the applicable settlement date; and 
 (b) if a Termination Event, Early
Settlement, or Fundamental Change Early Settlement shall have occurred prior to the Purchase Contract Settlement Date, Transfer the Applicable Ownership Interests in Mandatory Convertible Preferred Stock, the Cash, the Treasury Security or the
Applicable Ownership Interests in the Treasury Portfolio, as the case may be, underlying each Unit evidenced by such Certificate, in each case subject to the applicable conditions and in accordance with the applicable provisions of
Section 3.16(a) and Article 5 hereof. 

  
 32 

 The Purchase Contract Agent shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Agreement or under applicable law with respect to any transfer of any interest in any Certificate (including any transfers between or among Beneficial Owners of interests in any Global
Certificate) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Agreement, and to examine the same to determine
substantial compliance as to form with the express requirements hereof. 
 Section 3.06. Book-entry Interests. The
Certificates will be issued in the form of one or more fully registered Global Certificates, to be delivered to the Depositary or its custodian by, or on behalf of, the Company. The Company hereby designates DTC as the initial Depositary. Such
Global Certificates shall initially be registered on the Security Register in the name of Cede & Co., the nominee of the Depositary, and no Beneficial Owner will receive a definitive Certificate representing such Beneficial Owner’s
interest in such Global Certificate, except as provided in Section 3.08. The Purchase Contract Agent shall enter into an agreement with the Depositary in form and substance satisfactory to the Purchase Contract Agent if so
requested by the Company. Following the issuance of such Global Certificates and unless and until definitive, and fully registered Certificates have been issued to Beneficial Owners pursuant to Section 3.08: 

(a) the provisions of this Section 3.06 shall be in full force and effect; 

(b) the Company and the Purchase Contract Agent shall be entitled to deal with the Depositary for all purposes of this Agreement (including,
without limitation, making Contract Adjustment Payments, providing notices and receiving approvals, votes or consents hereunder) as the Holder of the Units and the sole holder of the Global Certificates and shall have no obligation to the Beneficial
Owners; provided that a Beneficial Owner may directly enforce against the Company, without any consent, proxy, waiver or involvement of the Depositary of any kind, such Beneficial Owner’s right to receive a definitive Certificate
representing the Units beneficially owned by such Beneficial Owner, as set forth in Section 3.08; 
 (c) to the
extent that the provisions of this Section 3.06 conflict with any other provisions of this Agreement, the provisions of this Section 3.06 shall control; and 

(d) except as set forth in the proviso of clause (b) of this Section 3.06, the
rights of the Beneficial Owners shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such Beneficial Owners and the Depositary or the Depositary Participants. The Depositary will make
book-entry transfers among Depositary Participants and receive and transmit payments of Contract Adjustment Payments to such Depositary Participants. 

Transfers of securities evidenced by Global Certificates shall be made through the facilities of the Depositary, and any cancellation of, or increase or
decrease in the number of, such securities (including the creation of Treasury Units, the creation of Cash Settled Units and the recreation of Corporate Units pursuant to Section 3.12(a),
Section 3.13(a) and Section 3.14(a) or Section 3.15(a), respectively) shall be accomplished by the Purchase Contract Agent in its capacity as paying agent making
appropriate annotations on the Schedule of Increases and Decreases set forth in such Global Certificate. 

  
 33 

 Section 3.07. Appointment of Successor Depositary. If the Depositary
elects to discontinue its services as securities depositary with respect to the Units, the Company may, in its sole discretion, appoint a successor Depositary with respect to the Units. 

Section 3.08. Definitive Certificates. 

If: 
 (a) the Depositary notifies the Company
that it is unwilling or unable to continue its services as securities depositary with respect to the Units and no successor Depositary has been appointed pursuant to Section 3.07 within 90 days after such notice; 

(b) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act when the Depositary is
required to be so registered to act as the Depositary and so notifies the Company, and no successor Depositary has been appointed pursuant to Section 3.07 within 90 days after such notice; 

(c) to the extent permitted by the Depositary, the Company determines in its discretion that the Global Certificates shall be exchangeable for
definitive Certificates and Beneficial Owners elect to withdraw their interests in the Global Certificates; or 
 (d) a Beneficial Owner
seeking to exercise or enforce its rights under the Corporate Units, Treasury Units or Cash Settled Units requests to exchange such Beneficial Owner’s interest in the Global Certificates for definitive Certificates; 

then (x) definitive Certificates shall be prepared by the Company with respect to such Units and delivered to the Purchase Contract Agent, together with
an Issuer Order for authentication, and (y) upon surrender of the Global Certificates representing the Units by the Depositary, accompanied by registration instructions, the Company shall cause definitive Certificates to be delivered to
Beneficial Owners in accordance with instructions provided by the Depositary. The Company and the Purchase Contract Agent shall not be liable for any delay in delivery of such instructions and may conclusively rely on and shall be authorized and
protected in relying on, such instructions. Each definitive Certificate so delivered shall evidence Units of the same kind and tenor as the Global Certificate (or beneficial interests in a Global Certificate) so surrendered in respect thereof. 

Section 3.09. Mutilated, Destroyed, Lost and Stolen Certificates. If any mutilated Certificate is surrendered to the
Purchase Contract Agent, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall, upon receipt of an Issuer Order, authenticate, execute on behalf of the Holder as their attorney-in-fact, and deliver to the Holder in exchange therefor, a new Certificate, evidencing the same number of Corporate Units, Treasury Units or Cash Settled Units, as
the case may be, and bearing a Certificate number not contemporaneously outstanding. 
 If there shall be (i) delivered to the Company and the Purchase
Contract Agent evidence to their satisfaction of the destruction, loss or theft of any Certificate, and (ii) furnished to the Company and the Purchase Contract Agent such security and/or indemnity satisfactory to the Purchase Contract Agent and
the Company to hold each of them and any agent of any of them harmless 

  
 34 

 
against any and all related loss, liability, cost, claim and expense, then, in the absence of notice to the Company or the Purchase Contract Agent that such Certificate has been acquired by a
protected purchaser, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall, upon receipt of an Issuer Order, authenticate, execute on behalf of the Holder as their
attorney-in-fact, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Certificate, a new Certificate, evidencing the same number of Corporate Units,
Treasury Units or Cash Settled Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding. 
 Notwithstanding the
foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to authenticate, execute on behalf of the Holder as its attorney-in-fact, and deliver to the Holder, with respect to such mutilated, destroyed, lost or stolen Certificate, a new Certificate on or after the Business Day immediately preceding the earliest of any
Early Settlement Date with respect to such lost, stolen, destroyed or mutilated Certificate, any Fundamental Change Early Settlement Date with respect to such lost, stolen, destroyed or mutilated Certificate, the Purchase Contract Settlement Date or
the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Purchase Contract
Agent shall: 
 (a) if the Purchase Contract Settlement Date, an Early Settlement Date or a Fundamental Change Early Settlement Date with
respect to such lost, stolen, destroyed or mutilated Certificate has occurred, deliver (or cause to be delivered) the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Units evidenced by such Certificate; and

 (b) if a Termination Event, Fundamental Change Early Settlement or an Early Settlement with respect to such lost, stolen, destroyed or
mutilated Certificate shall have occurred prior to the Purchase Contract Settlement Date, transfer the Applicable Ownership Interests in Mandatory Convertible Preferred Stock, the Treasury Security, the Applicable Ownership Interests in the Treasury
Portfolio or the Cash, as the case may be, underlying each Unit evidenced by such Certificate, in each case subject to the applicable conditions and in accordance with the applicable provisions of Section 3.16(a) and
Article 5 hereof. 
 Upon the issuance of any new Certificate under this Section 3.09, the Company and
the Purchase Contract Agent may require the payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other fees and expenses incurred by the Company or the Purchase
Contract Agent (including, without limitation, the fees and expenses of their respective counsel) in connection therewith. 
 Every new Certificate issued
pursuant to this Section 3.09 in lieu of any destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Units evidenced thereby,
whether or not the destroyed, lost or stolen Certificate (and the Units evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and
proportionately with any and all other Certificates delivered hereunder. 

  
 35 

 The provisions of this Section 3.09 are exclusive and shall preclude, to the
extent lawful, all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. 

Section 3.10. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Company,
the Collateral Agent, and the Purchase Contract Agent and any agent of the Company, the Collateral Agent or the Purchase Contract Agent, may treat the Person in whose name such Certificate is registered as the absolute owner of the Units evidenced
thereby for purposes of any payment or distribution with respect to the Applicable Ownership Interests in Mandatory Convertible Preferred Stock, on the Treasury Security, on the Applicable Ownership Interests in the Treasury Portfolio or payment of
Contract Adjustment Payments (in each case, subject to any Record Date or other applicable record date) and for purposes of performance of the Purchase Contracts and for all other purposes whatsoever in connection with such Units (subject to the
proviso in Section 3.06(b)), whether or not such payment, distribution, or performance shall be overdue and notwithstanding any notice to the contrary, and neither the Company nor the Purchase Contract Agent, nor any agent of the Company
or the Purchase Contract Agent, shall be affected by, or incur any liability as a result of, notice to the contrary. 
 Neither the Purchase Contract Agent
nor the Security Registrar shall have any responsibility or obligation to any Beneficial Owner of Units represented by a Global Certificate or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any agent
member, with respect to any ownership interest in the Units or with respect to the delivery to any agent member, Beneficial Owner or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such
Units. All notices and communications to be given to the Holders and all payments to be made to Holders pursuant to the Units and this Agreement shall be given or made only to or upon the order of the registered holders (which shall be the
Depositary or its nominee in the case of a Global Certificate). The rights of Beneficial Owners of the Units underlying a Global Certificate shall be exercised only through the Depositary subject to its applicable procedures. The Purchase Contract
Agent and the Security Registrar shall be entitled to conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any Beneficial Owners. The Purchase Contract
Agent and the Security Registrar shall be entitled to deal with the Depositary, and any nominee thereof, that is the registered holder of any Global Certificate for all purposes of this Agreement relating to such Global Certificate (including the
payment of Contract Adjustment Payments and the giving of instructions or directions by or to the Beneficial Owner in any Units underlying such Global Certificate) as the sole Holder of such Global Certificate and shall have no obligations to the
Beneficial Owners thereof (subject to the proviso in Section 3.06(b)). Neither the Purchase Contract Agent nor the Security Registrar shall have any responsibility or incur any liability for any acts or omissions of the Depositary with
respect to any Units underlying such Global Certificate, for the records of the Depositary, including records in respect of beneficial ownership interests in respect of Units underlying such Global Certificate, for any transactions between the
Depositary and any agent member or between or among the Depositary, any such agent member and/or any Holder or Beneficial Owner of any Units underlying such Global Certificate, or for any transfers of beneficial interests in any Units underlying
such Global Certificate. 

  
 36 

 Notwithstanding the foregoing, with respect to any Global Certificate, nothing contained herein shall
prevent the Company, the Purchase Contract Agent or any agent of the Company or the Purchase Contract Agent, from giving effect to any written certification, proxy or other authorization furnished by the Depositary (or its nominee), as a Holder,
with respect to such Global Certificate, or impair, as between such Depositary and the related Beneficial Owner, the operation of customary practices governing the exercise of rights of the Depositary (or its nominee) as Holder of such Global
Certificate. None of the Company, the Purchase Contract Agent or any agent of the Company or the Purchase Contract Agent will have any responsibility or incur any liability for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Certificate or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Section 3.11. Cancellation. All Certificates surrendered for delivery of shares of Common Stock on or after the Purchase
Contract Settlement Date or in connection with an Early Settlement or a Fundamental Change Early Settlement or for delivery of the Mandatory Convertible Preferred Stock underlying the Applicable Ownership Interests in Mandatory Convertible Preferred
Stock, the Applicable Ownership Interests in the Treasury Portfolio or the Cash proceeds of the Treasury Security, as the case may be, after the occurrence of a Termination Event, an Early Settlement or a Fundamental Change Early Settlement, a
Collateral Substitution, or upon the registration of transfer or exchange of a Unit, shall, if surrendered to any Person other than the Purchase Contract Agent, be delivered to the Purchase Contract Agent along with appropriate written instructions
regarding the cancellation thereof and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Purchase Contract Agent for cancellation any Certificates previously authenticated, executed and
delivered hereunder that the Company may have acquired in any manner whatsoever, and all Certificates so delivered shall, upon an Issuer Order, be promptly cancelled by the Purchase Contract Agent. No Certificates shall be authenticated, executed on
behalf of the Holder and delivered in lieu of or in exchange for any Certificates cancelled as provided in this Section 3.11, except as expressly permitted by this Agreement. All cancelled Certificates held by the Purchase
Contract Agent shall be disposed of in accordance with its then customary practices. With respect to any Certificates that it has acquired, the Purchase Contract Agent may be entitled to conclusively rely on such Issuer Order as it relates to the
ownership by the Company of such Certificate. 
 If the Company or any Affiliate of the Company shall acquire any Certificate, such acquisition shall not
operate as a cancellation of such Certificate unless and until such Certificate is delivered to the Purchase Contract Agent for cancellation. 

Section 3.12. Creation of Treasury Units by Substitution of Treasury Security. (a) Subject to the conditions set forth
in this Agreement, and subject to the limitations on a Collateral Substitution in connection with an Optional Remarketing as set forth under Section 5.02(a)(i) below, a Holder of Corporate Units may, at any time from and
after the date of this Agreement, other than during a Blackout Period, effect a Collateral Substitution and separate the shares of Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible
Preferred Stock in respect of such Corporate Units by substituting for such Holder’s Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock for which Collateral Substitution is being made, Treasury Securities;

  
 37 

 
provided that Holders may make Collateral Substitutions only in integral multiples of 10 Corporate Units. To effect such substitution, the Holder must: 

(i) Transfer to the Collateral Agent, for credit to the Collateral Account, one Treasury Security and/or security entitlements
with respect thereto for every 10 Corporate Units with respect to which such substitution is being made (such amount shall, following receipt by the Company from the Purchase Contract Agent of a copy of the instruction from the Holder to the
Purchase Contract Agent in the form of Exhibit D, be calculated by the Company and provided to the Purchase Contract Agent in writing at such time it receives a copy of such notice from the Purchase Contract Agent); and 

(ii) Transfer the related Corporate Units to the Purchase Contract Agent accompanied by a notice to the Purchase Contract
Agent, substantially in the form of Exhibit D hereto, whereupon the Purchase Contract Agent shall (in accordance with instructions provided for in the aforementioned notice from Holders and upon completion of the
requirements of Section 3.12(a)(i) above) promptly provide an instruction to such effect to the Collateral Agent, substantially in the form of Exhibit G hereto. 

Upon confirmation that the Treasury Securities described in clause ((i)) above or security entitlements with respect thereto have been credited to the
Collateral Account and receipt of the written instruction to the Collateral Agent described in clause ((ii)) above, the Collateral Agent shall release such Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock from the
Pledge by directing the Securities Intermediary by a notice, substantially in the form of Exhibit H hereto, to Transfer the shares of Mandatory Convertible Preferred Stock underlying such Pledged Applicable Ownership
Interests in Mandatory Convertible Preferred Stock to the Purchase Contract Agent for distribution to such Holder as instructed by such Holder to the Purchase Contract Agent in accordance with the terms provided for herein, free and clear of the
Pledge created hereby. Notwithstanding anything to the contrary herein, the Securities Intermediary and the Collateral Agent shall take no action to release such Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock from
the Pledge unless and until the direction is provided by the Purchase Contract Agent substantially in the form of Exhibit G hereto. 

Upon credit to the Collateral Account of the Treasury Securities and/or security entitlements with respect thereto delivered by a Holder of Corporate Units
and receipt of the related instruction from the Collateral Agent, the Securities Intermediary shall promptly Transfer the shares of Mandatory Convertible Preferred Stock underlying the appropriate Pledged Applicable Ownership Interests in Mandatory
Convertible Preferred Stock to the Purchase Contract Agent for distribution to such Holder as instructed by such Holder to the Purchase Contract Agent in accordance with the terms provided for herein, free and clear of the Pledge created hereby.

 Upon receipt of the shares of Mandatory Convertible Preferred Stock underlying such Pledged Applicable Ownership Interests in Mandatory Convertible
Preferred Stock, the Purchase Contract Agent shall promptly: 
 (A) cancel the related Corporate Units; 

  
 38 

 (B) Transfer such shares of Mandatory Convertible Preferred Stock to the
Holder (such shares of Mandatory Convertible Preferred Stock shall constitute Separate Shares of Mandatory Convertible Preferred Stock and be tradable as separate securities, independent of the concurrently created Treasury Units) in book-entry
form, to the extent a Global Preferred Share is registered in the name of the Depositary or its nominee; and 
 (C) cause
the Collateral Agent to deliver Treasury Units in book-entry form, or if applicable, cause the Collateral Agent to deliver the Treasury Units to the Purchase Contract Agent, upon receipt of which the Purchase Contract Agent shall authenticate,
execute on behalf of such Holder as their attorney-in-fact and deliver Treasury Units in the form of a Treasury Units Certificate executed by the Company in accordance
with Section 3.03 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Corporate Units. 
 Holders
who elect to separate the shares of Mandatory Convertible Preferred Stock by substituting Treasury Securities for Applicable Ownership Interests in Mandatory Convertible Preferred Stock shall be responsible for any taxes, governmental charges or
other fees or expenses (including, without limitation, the reasonable fees and expenses payable to the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary and their respective counsel), in respect of
such Collateral Substitution, and neither the Company nor the Purchase Contract Agent nor the Collateral Agent nor the Securities Intermediary shall be responsible for any such taxes, governmental charges or other fees or expenses. 

(b) In the event a Holder making a Collateral Substitution pursuant to Section 3.12(a) fails to effect a book-entry
transfer of the Corporate Units or fails to deliver Corporate Units Certificates to the Purchase Contract Agent after depositing Treasury Securities and/or security entitlements with respect thereto with the Collateral Agent, any distributions on
the shares of Mandatory Convertible Preferred Stock underlying the Applicable Ownership Interests in Mandatory Convertible Preferred Stock constituting a part of such Corporate Units, shall be held in the name of the Purchase Contract Agent or its
nominee in trust for the benefit of such Holder, until such Corporate Units are so transferred or the Corporate Units Certificate is so delivered, as the case may be, or such Holder provides evidence satisfactory to the Company and the Purchase
Contract Agent that such Corporate Units Certificate has been destroyed, lost or stolen, together with any indemnity and/or security that may be required by the Purchase Contract Agent and the Company. 

(c) Except as described in Section 5.02, Section 3.12(a),
Section 3.13(a) or in connection with an Early Settlement, a Fundamental Change Early Settlement or a Termination Event, for so long as the Purchase Contract underlying a Corporate Unit remains in effect, such Corporate
Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder in respect of the Mandatory Convertible Preferred Stock and the Purchase Contract comprising such Corporate Units may be acquired, and may be
transferred and exchanged, only as a Corporate Unit and in the manner provided for in Exhibit D attached hereto. 

  
 39 

 Section 3.13. Creation of Cash Settled Units by Substitution of Cash.
(a) Subject to the conditions set forth in this Agreement, a Holder of Corporate Units may, at any time from and after the date the Company gives a Notice of a Final Remarketing as set forth in Section 5.02(b)(ii)

at such time that the Company receives a copy of such notice from the Purchase Contract Agent); and

Upon receipt of the shares of Mandatory Convertible Preferred Stock underlying such Pledged Applicable Ownership Interests in Mandatory Convertible Preferred

payable to the Purchase Contract Agent, the Collateral Agent, the Custodial Agent, the Securities Intermediary and their respective counsel), in respect of such Collateral Substitution, and neither the Company nor the Purchase Contract Agent shall
be responsible for any such taxes, governmental charges or other fees or expenses. 
 (b) In the event a Holder making a Collateral
Substitution pursuant to Section 3.13(a) fails to effect a book-entry transfer of the Corporate Units or fails to deliver Corporate Units Certificates to the Purchase Contract Agent after depositing Cash with the Collateral
Agent, any distributions on the shares of Mandatory Convertible Preferred Stock underlying the Applicable Ownership Interests in Mandatory Convertible Preferred Stock constituting a part of such Corporate Units, shall be held in the name of the
Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until such Corporate Units are so transferred or the Corporate Units Certificate is so delivered, as the case may be, or such Holder provides evidence satisfactory to
the Company and the Purchase Contract Agent that such Corporate Units Certificate has been destroyed, lost or stolen, together with any indemnity or security that may be required by the Purchase Contract Agent and the Company.

notice to the Purchase Contract Agent, substantially in the form of Exhibit D hereto, whereupon the Purchase Contract Agent, upon completion of the requirements of Section 3.14(a)(i) above, shall (in accordance with
the instructions provided for in the aforementioned notice from the Holder) promptly provide an instruction to the Collateral Agent substantially in the form of Exhibit K hereto. 

Upon confirmation that the shares of Mandatory Convertible Preferred Stock described in clause ((i)) above or security entitlements with respect thereto

their respective counsel), in respect of the recreation, and neither the Company nor the Purchase Contract Agent nor the Collateral Agent shall be responsible for any such taxes, governmental charges or other fees or expenses. 

(b) Except as provided in Section 5.02 or in Section 3.14(a) or in connection with an Early
Settlement, a Fundamental Change Early Settlement or a Termination Event, for so long as the Purchase Contract underlying a Treasury Unit remains in effect, such Treasury Unit shall not be separable into its constituent parts and the rights and

receives a copy of such notice from the Purchase Contract Agent); and 
 (ii) Transfer the related Cash Settled Units to the
Purchase Contract Agent accompanied by a notice to the Purchase Contract Agent, substantially in the form of Exhibit D hereto, whereupon the Purchase Contract Agent, upon completion of the requirements of

 (b) Except as provided
in Section 5.02 or in Section 3.15(a) or in connection with a Fundamental Change Early Settlement or a Termination Event, for so long as the Purchase Contract underlying a Cash Settled Unit remains
in effect, such Cash Settled Unit shall not be separable into its constituent parts and the rights and obligations of the Holder of such Cash Settled Unit in respect of the interest in the Cash and the Purchase Contract comprising such Cash Settled
Unit may be acquired, and may be transferred and exchanged, only as a Cash Settled Unit. 
 Section 3.16. Transfer of Collateral
Upon Occurrence of Termination Event. (a) Upon the occurrence of a Termination Event, the Company shall notify the Purchase Contract Agent and the Collateral Agent in writing of the occurrence thereof and request that the Collateral
Agent request the Securities Intermediary to release the Collateral from the Pledge. Upon receipt by the Collateral Agent of such written notice or written notice pursuant to Section 5.05 hereof from the Company that a
Termination Event has occurred, the Collateral Agent shall promptly release all Collateral from the Pledge by directing the Securities Intermediary to Transfer all (in accordance with the instructions provided for in the aforementioned notice from

 45 

 
shall issue fractional shares of Mandatory Convertible Preferred Stock, each with a liquidation preference of $100, or integral multiples thereof, in exchange for whole shares of Mandatory
Convertible Preferred Stock or integral multiples thereof; and provided further, if any Holder shall be entitled to receive, with respect to its Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, any securities
having a principal amount at maturity of less than the minimum denominations thereof, the Purchase Contract Agent shall dispose of such Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities for Cash and deliver to such
Holder Cash in lieu of delivering the Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, upon receipt of and in accordance with instructions to be separately provided by such Holder. 

(b) Notwithstanding anything to the contrary in Section 3.16(a), if such Termination Event shall result from the
Company’s becoming a debtor under the Bankruptcy Code, and if the Collateral Agent shall for any reason fail promptly to effectuate the release and Transfer of all shares of Mandatory Convertible Preferred Stock underlying Pledged Applicable
Ownership Interests in Mandatory Convertible Preferred Stock, Applicable Ownership Interests in the Treasury Portfolio, Pledged Cash, Pledged Treasury Securities and payments by Holders (or the Permitted Investments of such payments) pursuant to
Section 5.02 and Proceeds and all other payments received by the Collateral Agent in respect of the foregoing, as the case may be, as provided by Section 3.16(a), the Company shall use its best
efforts to obtain an opinion of a nationally recognized law firm to the effect that, notwithstanding the Company’s being the debtor in such a bankruptcy case, the Collateral Agent will not be prohibited from releasing or Transferring the
Collateral as provided in Section 3.16(a), and shall deliver or cause to be delivered such opinion addressed to the Collateral Agent within ten days after the occurrence of such Termination Event, and if (A) the
Company shall be unable to obtain such opinion within ten days after the occurrence of such Termination Event or (B) the Collateral Agent shall continue, after delivery of such opinion, to refuse to effectuate the release and Transfer of all
shares of Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, Applicable Ownership Interests in the Treasury Portfolio, Pledged Cash, Pledged Treasury Securities and the
payments by Holders (or the Permitted Investments of such payments) pursuant to Section 5.02 hereof and Proceeds and all other payments received by the Collateral Agent in respect of the foregoing, as the case may be, as
provided in Section 3.16(a), then the Purchase Contract Agent shall within fifteen days after its receipt of written notice from the Company of the occurrence of such Termination Event commence an action or proceeding in
the court having jurisdiction of the Company’s case under the Bankruptcy Code seeking an order requiring the Collateral Agent to effectuate the release and transfer of all shares of Mandatory Convertible Preferred Stock underlying Pledged
Applicable Ownership Interests in Mandatory Convertible Preferred Stock, Applicable Ownership Interests in the Treasury Portfolio, Pledged Cash, Pledged Treasury Securities and the payments by Holders (or the Permitted Investments of such payments)
pursuant to Section 5.02 hereof and Proceeds and all other payments received by the Collateral Agent in respect of the foregoing, or as the case may be, as provided by Section 3.16(a). 

 

  
 46 

 (c) Upon receipt by the Purchase Contract Agent of written notice from the Company pursuant

instructions with respect to such Mandatory Convertible Preferred Stock, Applicable Ownership Interests in the Treasury Portfolio, Pledged Cash or Pledged Treasury Securities, as the case may be, from each Holder by written request, substantially in
the form of Exhibit F hereto, mailed to such Holder at its address as it appears in the Security Register.

book-entry transfer, or other appropriate procedures, in accordance with such instructions and, in the case of the shares of Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred
Stock, in accordance with the terms of the Certificate of Designations. In the event a Holder of Corporate Units, Treasury Units or Cash Settled Units fails to deliver transfer instructions or effect such transfer or delivery, the shares of
Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, the Applicable Ownership Interests in the Treasury Portfolio, the applicable Treasury Securities or Pledged Cash, as
the case may be, underlying such Corporate Units, Treasury Units or Cash Settled Units, as the case may be, and any distributions thereon, shall be held in the name of the Purchase Contract Agent or its nominee in trust for the benefit of such
Holder, until the earlier to occur of: 
 (i) the transfer of such Corporate Units, Treasury Units or Cash Settled Units or
surrender of the Corporate Units Certificate, Treasury Units Certificate or Cash Settled Units Certificate or the receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such Corporate Units Certificate,
Treasury Units Certificate or Cash Settled Units Certificate has been destroyed, lost or stolen, together with any indemnity and/or security that may be required by the Purchase Contract Agent and the Company; and 

(ii) the expiration of the time period specified by the applicable law governing abandoned property in the state in which the
Purchase Contract Agent holds such property. 
 Notwithstanding the foregoing, upon written instruction from the Company, the Purchase Contract Agent shall
deliver to the Company any funds or property held for two years, in which event the Company shall have sole responsibility for compliance with all applicable escheat laws with respect to all funds or property returned to it pursuant to this
sentence.

 Section 3.17. No Consent to Assumption. Each Holder of a Unit, by
acceptance thereof, shall be deemed expressly to have (a) withheld any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its trustee, receiver, liquidator or a
person or entity performing similar functions in the event that the Company becomes a debtor under the Bankruptcy Code or subject to other similar state or Federal law providing for reorganization or liquidation and (b) agreed with the Company,
the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary that the transaction contemplated by the Purchase Contract constitutes a “swap agreement” within the meaning of Section 101 (53B)
of the Bankruptcy Code and that each such Holder shall constitute a “swap participant” within the meaning of Section 101 (53C) of the Bankruptcy Code. 

Section 3.18. Substitutions. Whenever a Holder has the right to substitute Cash or shares of Mandatory Convertible
Preferred Stock underlying Applicable Ownership Interests in Mandatory Convertible Preferred Stock, as the case may be, or security entitlements for any of them for financial assets held in the Collateral Account, such substitution shall not
constitute a novation of the security interest created hereby.

Treasury Portfolio that formerly comprised a part of such Holder’s Corporate Units, such Holder shall be entitled to receive dividends, if any, on such Separate Shares of Mandatory Convertible Preferred Stock or distributions on such Applicable
Ownership Interests in the Treasury Portfolio.

 Section 4.02. Payments Prior to or on Purchase Contract Settlement Date.
(a) Subject to the provisions of Section 5.02, Section 5.04 and Section 5.06(a), and except as provided in Section 4.02(b) below, if no
Termination Event shall have occurred, all payments received by the Securities Intermediary in respect of (1) the proceeds received in a Successful Remarketing attributable to the shares of Mandatory Convertible Preferred Stock underlying
Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, (2) the Pledged Applicable Ownership Interests in the Treasury Portfolio and (3) the Pledged Treasury Securities, shall be credited to the Collateral Account,
to be invested as directed in writing by the Company in Permitted Investments until the Purchase Contract Settlement Date, and such payments (or proceeds of such Permitted Investments, if applicable), shall be transferred to the Company on the
Purchase Contract Settlement Date as provided in Section 5.02 hereof to the extent necessary to satisfy the Holder’s obligation pursuant to Section 5.01 hereof to pay the Purchase Price to
settle the Purchase Contracts. Any balance thereafter remaining in the Collateral Account shall be released from the Pledge and transferred to the Purchase Contract Agent for the benefit of the applicable Holders as their attorney-in-fact for distribution to such Holders in accordance with their respective interests pursuant to Section 11.02 hereof, free and clear of the Pledge created
hereby. The Company shall instruct the Collateral Agent in writing as to the specific Permitted Investments in which any payments made under this Section 4.02(a) shall be invested, provided, however, that if the
Company fails to deliver such instructions by 10:30 a.m. (New York City time) on the day such payments are received by the Securities Intermediary, the Collateral Agent shall instruct the Securities Intermediary to invest such payments in the
Permitted Investments (if any), which have been designated by the Company in writing from time to time in a standing instruction to the Securities Intermediary which shall be effective until revoked or superseded. If no such standing instruction
exists, such funds shall remain uninvested with no liability for interest therein. In no event shall the Collateral Agent or the Securities Intermediary be liable for the selection of Permitted Investments or for investment losses incurred thereon;
provided, further, however, that all Permitted Investments shall mature on or prior to the Purchase Contract Settlement Date. In no event shall the Collateral Agent or the Securities Intermediary be liable for the selection of
Permitted Investments or for any losses, fees, taxes or other charges arising from any investment, reinvestment or liquidation of Permitted Investments made hereunder. Neither the Collateral Agent nor the Securities Intermediary shall have any
liability in respect of losses, fees, taxes or other charges incurred based on acting or omitting to act under this Section 4.02(a) pursuant to any direction of the Company or as a result of the failure of the Company to
provide timely written investment direction. Any interest or other income received on such investment and reinvestment of the funds shall become part of the Collateral Account and any losses, fees, taxes or other charges incurred on such investment
and reinvestment of the funds shall be debited against the Collateral Account. For the avoidance of doubt, no such losses, fees, taxes or other charges shall affect the Company’s obligations under Article 5 and
Holders’ obligations shall remain subject to Section 5.02(i). It is agreed and understood that the entity serving as Purchase Contract Agent, Collateral Agent or Securities Intermediary may earn fees associated with
the investments outlined above in accordance with the terms of such investments. In no event shall the Purchase Contract Agent, Securities Intermediary or the Collateral Agent be deemed an investment manager or adviser in respect of any selection of
investments hereunder. It is understood and agreed that the Purchase Contract 

  
 50 

 
Agent, Securities Intermediary or the Collateral Agent or their respective affiliates are permitted to receive additional compensation that could be deemed to be in the Purchase Contract
Agent’s, Securities Intermediary’s or the Collateral Agent’s economic self-interest for (1) serving as investment adviser, administrator, shareholder servicing agent, custodian or sub custodian with respect to certain of the
investments, (2) using affiliates to effect transactions in certain investments and (3) effecting transactions in investments. 

(b) All payments received by the Securities Intermediary in respect of (1) the Mandatory Convertible Preferred Stock, (2) the
Applicable Ownership Interests in the Treasury Portfolio and (3) the Treasury Securities or security entitlements with respect thereto, that, in each case, have been released from the Pledge pursuant hereto shall be transferred to the Purchase
Contract Agent for the benefit of the applicable Holders for distribution to such Holders in accordance with their respective interests and the terms of this Agreement. 

(c) Reserved. 

Section 4.03. Notice and Voting. (a) Subject to Section 4.03(b) hereof, the Purchase
Contract Agent shall exercise, or refrain from exercising, any and all voting and other consensual rights pertaining to the Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred
Stock or any part thereof for any purpose not inconsistent with the terms of this Agreement. Upon receipt of any notices and other communications in respect of any Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership
Interests in Mandatory Convertible Preferred Stock, including either notice of any meeting at which holders of the Mandatory Convertible Preferred Stock are entitled to vote or the solicitation of consents, waivers or proxies of holders of the
Mandatory Convertible Preferred Stock, the Collateral Agent shall use commercially reasonable efforts to send promptly to the Purchase Contract Agent such notice or communication, and as soon as reasonably practicable after receipt of a written
request therefor from the Purchase Contract Agent acting as attorney-in-fact for the Holders, to execute and deliver to the Purchase Contract Agent such proxies and
other instruments in respect of such Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock (in commercially reasonable form and substance) as are prepared by the Company and
delivered to the Collateral Agent for delivery to the Purchase Contract Agent with respect to the Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock. 

(b) Upon receipt of notice of any meeting at which holders of Mandatory Convertible Preferred Stock are entitled to vote or upon any
solicitation of consents, waivers or proxies of holders of Mandatory Convertible Preferred Stock, the Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage pre-paid, to
the Holders of Corporate Units a notice: 
 (i) containing such information as is contained in the notice or solicitation;

  
 51 

 (ii) stating that each Holder on the record date set by the Purchase
Contract Agent therefor (which, to the extent possible, shall be the same date as the record date set by the Company for determining the holders of shares of Mandatory Convertible Preferred Stock entitled to vote) shall be entitled to instruct the
Purchase Contract Agent in writing as to the exercise of the voting rights pertaining to the Mandatory Convertible Preferred Stock underlying Applicable Ownership Interests in Mandatory Convertible Preferred Stock that are a component of their
Corporate Units; and 
 (iii) stating the manner in which such instructions may be given. 

Upon the written request of the Holders of Corporate Units on such record date (which must be received by the Purchase Contract Agent at least six days prior
to such meeting) or the expiration date of any consent solicitation, the Purchase Contract Agent shall endeavor insofar as practicable to vote or cause to be voted or to consent with respect to, in accordance with the instructions set forth in such
requests, the maximum aggregate number of shares of Mandatory Convertible Preferred Stock as to which any particular voting or consenting instructions are received. In the absence of specific instructions from the Holder of Corporate Units, the
Purchase Contract Agent shall abstain from voting or consenting with respect to the Mandatory Convertible Preferred Stock underlying Applicable Ownership Interests in Mandatory Convertible Preferred Stock that are a component of such Corporate
Units. The Company hereby agrees, if applicable, to solicit Holders of Corporate Units to timely instruct the Purchase Contract Agent in writing as to the exercise of such voting or consenting rights in order to enable the Purchase Contract Agent to
vote or consent with respect to such Mandatory Convertible Preferred Stock as the attorney-in-fact for the Holders. Notwithstanding anything in this Agreement to the
contrary, in the event that such Mandatory Convertible Preferred Stock are held by or through DTC or another Depositary, the exercise of a Holder’s right to vote shall occur in conformity with the Applicable Procedures and standing arrangements
between DTC or such Depositary and the Company or the Purchase Contract Agent.

Person holding a beneficial interest in such Global Certificate may be considered to be a “Holder” of Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests Mandatory Convertible Preferred Stock for
purposes of voting on the matters relating thereto (for example, such Person holding a beneficial interest in such Global Certificate may consent to any waiver or amendment directly without requiring the participation of DTC or its nominee); it
being understood that if such Person holding a beneficial interest in such Global Certificate is authorized pursuant to an official DTC proxy, or if the Purchase Contract Agent receives evidence satisfactory to the Purchase Contract Agent (in its
sole discretion) that (a) such Person holds the beneficial interests in such Global Certificate that it purports to vote (such evidence of ownership may include a securities position or participant list or other information obtained from DTC)
and (b) such beneficial interest in such Global Certificate shall remain so owned for purposes of such vote, then the Purchase Contract Agent may recognize such Person for purposes of voting. 

  
 52 

 (e) In connection with any vote of the Holders as required under the terms hereof, the
Purchase Contract Agent may at the expense of the Company appoint an independent third party solicitation agent (the “Solicitation Agent”) to conduct any solicitation of consents as required under the terms hereof. The
Solicitation Agent shall report the results of any such solicitation taken under the terms hereof to the Purchase Contract Agent to enable the Purchase Contract Agent to exercise the voting rights of such Holders as the attorney-in-fact for such Holders. In the absence of gross negligence or willful misconduct by the Purchase Contract Agent, the Purchase Contract Agent may conclusively rely
and shall be fully protected in acting or refraining from acting upon the results provided to it by such Solicitation Agent. 

Section 4.04. Payments to Purchase Contract Agent. The Securities Intermediary shall use commercially reasonable efforts to
deliver any payments required to be made by it to the Purchase Contract Agent hereunder to the account designated by the Purchase Contract Agent for such purpose not later than 10:00 a.m. (New York City time) on the Business Day such payment is
received by the Securities Intermediary; provided, however, that if such payment is received by the Securities Intermediary on a day that is not a Business Day or after 10:00 a.m. (New York City time) on a Business Day, then the Securities

Securities to the Purchase Contract Agent hereunder, the Collateral Agent shall cause such Transfer to be made at the Corporate Trust Office. 

Section 4.05. Payments Held In Trust. If the Purchase Contract Agent or any Holder shall receive any payments on account of
financial assets credited to the Collateral Account and not released therefrom in accordance with this Agreement, the Purchase Contract Agent or such Holder shall hold such payments as trustee of an express trust for the benefit of the Company and,
upon receipt of an Officer’s Certificate of the Company so directing, promptly deliver such payments to the Securities Intermediary for credit to the Collateral Account or to the Company for application to the Obligations of the applicable
Holder or Holders, and the Purchase Contract Agent and Holders shall acquire no right, title or interest in any such payments of principal amounts so received.

 55 

 (a) Optional Remarketing. (i) Unless a Termination Event has occurred, the
Company may elect, at its option, to engage the Remarketing Agent(s), pursuant to the terms of the Remarketing Agreement, to remarket the aggregate number of shares of Mandatory Convertible Preferred Stock underlying the aggregate Applicable
Ownership Interests in Mandatory Convertible Preferred Stock that are components of Corporate Units, along with any Separate Shares of Mandatory Convertible Preferred Stock, the holders of which have elected to participate in such Remarketing

Window. 
 (ii) The Company shall issue a press release and notify the Purchase Contract Agent and the Custodial Agent in
writing and request that the Depositary notify the Depositary Participants holding Corporate Units, Treasury Units and Separate Shares of Mandatory Convertible Preferred Stock as to the dates and procedures to be followed in any Optional Remarketing
no later than fifteen (15) calendar days prior to the first day of an Optional Remarketing Period, and the Company shall provide a copy of such request to the Purchase Contract Agent, the Collateral Agent and the Custodial Agent. 

(iii) If the Company elects to conduct an Optional Remarketing, by 11:00 a.m. (New York City time) on the Business Day
immediately preceding the first day of an Optional Remarketing Period, the Company shall notify (i) the Purchase Contract Agent in writing of the aggregate number of shares of Mandatory Convertible Preferred Stock underlying the Pledged
Applicable Ownership Interests in Mandatory Convertible Preferred Stock that are a part of the Corporate Units to be remarketed and (ii) the Custodial Agent in writing of the aggregate number of Separate Shares of Mandatory Convertible
Preferred Stock (if any) to be remarketed pursuant to Section 5.02(d) below, and upon receipt of such written notice, (i) the Purchase Contract Agent shall notify in writing the Remarketing Agent(s) identified in such
notice of the aggregate number of shares of Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock that are a part of the Corporate Units to be remarketed, and
(ii) the Custodial Agent shall notify in writing the Remarketing Agent(s) identified in such notice of the aggregate number of Separate Shares of Mandatory Convertible Preferred Stock (if any) to be remarketed pursuant to
Section 5.02(d) below. The Company shall, and pursuant to, and subject to the terms of, the Remarketing Agreement, upon receipt of such notices from the Purchase Contract Agent and the Custodial Agent, the Company shall
cause the Remarketing Agent(s) pursuant to the Remarketing Agreement to, use its reasonable best efforts to remarket such shares of Mandatory Convertible Preferred Stock. For the avoidance of doubt, and without limiting the generality of the
foregoing, the Company and its Board of Directors shall accept the terms of a Successful Optional Remarketing if the Closing Price of the Common Stock at the time of any scheduled, proposed or purported Optional Remarketing Date is above the
Threshold Appreciation Price. The Company shall use commercially reasonable efforts to cooperate with the Purchase Contract Agent in connection with any Optional Remarketing and shall notify the Purchase Contract Agent in writing promptly upon
becoming aware of the expected Remarketing Date in connection with such Optional Remarketing. 

  
 56 

 (iv) If the Remarketing Agent(s) is able to remarket such Mandatory
Convertible Preferred Stock for at least the applicable Remarketing Price in any Optional Remarketing in accordance with the Remarketing Agreement (a “Successful Optional Remarketing”), the Company shall notify the Collateral Agent
and the Custodial Agent thereof in writing and upon receipt of such notice, the Collateral Agent shall cause the Securities Intermediary to transfer to the Remarketing Agent(s) the remarketed Mandatory Convertible Preferred Stock underlying the
Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock upon confirmation of deposit to the Collateral Account of proceeds of such Successful Optional Remarketing attributable to such Mandatory Convertible Preferred Stock
underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, and the Custodial Agent shall transfer the remarketed Separate Shares of Mandatory Convertible Preferred Stock to the Remarketing Agent(s) upon
confirmation of deposit to the separate account established by the Custodial Agent for the purpose of receiving such proceeds (the “Separate Account”), of receipt of proceeds of such Successful Optional Remarketing attributable to
such Separate Shares of Mandatory Convertible Preferred Stock. Settlement shall occur on the Optional Remarketing Settlement Date. Upon deposit in the Collateral Account of such proceeds attributable to the remarketed Mandatory Convertible Preferred
Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, the Collateral Agent shall, upon receipt of written instructions from the Company, (A) instruct the Securities Intermediary to apply an amount
equal to the Treasury Portfolio Purchase Price to purchase the Treasury Portfolio from the Quotation Agent (the amount and issue of the U.S. Treasury securities (or principal or interest strips thereof) constituting the Treasury Portfolio to be
determined by the Remarketing Agent(s), who shall provide such information to the Collateral Agent and the Quotation Agent, and the Quotation Agent will then determine, and notify the Collateral Agent of, the Treasury Portfolio Purchase Price), and
(B) credit to the Collateral Account the Applicable Ownership Interests in the Treasury Portfolio, and (C) promptly remit any remaining portion of such proceeds to the Purchase Contract Agent for payment to the Holders of Corporate Units,
whereupon the Purchase Contract Agent shall make such payment on the Optional Remarketing Settlement Date to the Holders whose Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible
Preferred Stock were remarketed pro rata in accordance with their respective interests. With respect to any Separate Shares of Mandatory Convertible Preferred Stock remarketed, upon receipt of proceeds of such Successful Optional Remarketing
attributable to the remarketed Separate Shares of Mandatory Convertible Preferred Stock, the Custodial Agent shall remit such proceeds of such Separate Shares of Mandatory Convertible Preferred Stock sold in the Successful Optional Remarketing
received from the Remarketing Agent(s) pro rata to holders of such Separate Shares of Mandatory Convertible Preferred Stock on the Optional Remarketing Settlement Date in accordance with the instructions by such holders provided in the form
of Exhibit M 
  

  
 57 

 (v) Following the occurrence of a Successful Optional Remarketing, the
Applicable Ownership Interests in the Treasury Portfolio will be substituted as Collateral for the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock and will be held by the Collateral Agent in accordance with the terms
hereof to secure the Obligation of each Holder of Corporate Units, and the Holders of Corporate Units and the Collateral Agent shall have such respective rights, obligations and security interests with respect to the Applicable Ownership Interests
in the Treasury Portfolio as the Holder of Corporate Units and the Collateral Agent had in respect of the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, subject to the Pledge thereof. Any reference in this Agreement
or the Certificates to the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock shall thereupon be deemed to be a reference to such Applicable Ownership Interests in the Treasury Portfolio. The Company may cause to be made
in any Corporate Units Certificates thereafter to be issued such change in phraseology and form (but not in substance) as may be appropriate to reflect the substitution of the Applicable Ownership Interests in the Treasury Portfolio for the Pledged
Applicable Ownership Interests in Mandatory Convertible Preferred Stock as Collateral. 
 (vi) Following a Successful
Optional Remarketing, the Remarketing Agent(s) shall remit (1) the proceeds attributable to the remarketed Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock to
the Collateral Agent and (2) the proceeds attributable to the remarketed Separate Shares of Mandatory Convertible Preferred Stock to the Custodial Agent for the benefit of the holders of Separate Shares of Mandatory Convertible Preferred Stock
that had their Separate Shares of Mandatory Convertible Preferred Stock remarketed. 
 (vii) If, in spite of its reasonable
best efforts, the Remarketing Agent(s) cannot remarket the Mandatory Convertible Preferred Stock as set forth above during the Optional Remarketing Period at a price not less than the applicable Remarketing Price or a condition precedent set forth
in the Remarketing Agreement is not fulfilled, the Optional Remarketing will be deemed to have been unsuccessful (an “Unsuccessful Optional Remarketing”). Promptly after receipt of written notice from the Company of an Unsuccessful
Optional Remarketing, the Custodial Agent will return Separate Shares of Mandatory Convertible Preferred Stock that were to be subject to the Optional Remarketing to the appropriate holders thereof in accordance with the instructions by such holders
provided in the form of Exhibit M. 
 (viii) If the Company elects to remarket the Mandatory Convertible Preferred
Stock during the Optional Remarketing Period and a Successful Optional Remarketing has not occurred on or prior to the last day of the Optional Remarketing Period, the Company shall cause a notice of the Unsuccessful Optional Remarketing to be
provided in writing to the Custodial Agent, the Collateral Agent and the Purchase Contract Agent and to be published before the open of business on the Business Day immediately following the last date of the Optional Remarketing Period. This notice
shall be validly published by making a timely release to any appropriate news agency, including, without limitation, Bloomberg Business News and the Dow Jones News Service. The Company shall similarly cause a notice of a Successful Optional
Remarketing to be provided in writing to the Custodial Agent, the Collateral Agent and the Purchase Contract Agent and to be published before the open of business on the Business Day immediately following the date of such Successful Optional
Remarketing, 

  
 58 

 
and the Company shall request the Depositary to notify its participants holding Separate Shares of Mandatory Convertible Preferred Stock, if any, of the modified terms established for the
Mandatory Convertible Preferred Stock during the Optional Remarketing on the Business Day following the date on which the Mandatory Convertible Preferred Stock was successfully remarketed (and a copy of this request shall be provided to the
Custodial Agent, the Collateral Agent and the Purchase Contract Agent). 
 (b) Final Remarketing. (i) Unless a Termination Event
or a Successful Optional Remarketing has occurred, in order to remarket the Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock of any Holders of Corporate Units, the
Company shall engage the Remarketing Agent(s), and the Company shall, and the Company shall cause the Remarketing Agent(s) pursuant to the terms of the Remarketing Agreement to, use its reasonable best efforts to remarket such Mandatory Convertible
Preferred Stock, along with any Separate Shares of Mandatory Convertible Preferred Stock, the holders of which have elected to participate in the Final Remarketing pursuant to Section 5.02(d) below, during the Final
Remarketing Period. For the avoidance of doubt, and without limiting the generality of the foregoing, the Company and its Board of Directors shall accept the terms of a Successful Final Remarketing if the Closing Price of the Common Stock at the
time of any scheduled, proposed or purported Final Remarketing Date is above the Threshold Appreciation Price. 
 (ii) The
Company shall substantially contemporaneously notify the Purchase Contract Agent and the Custodial Agent in writing, issue a press release, and request that the Depositary notify the Depositary Participants holding Corporate Units, Treasury Units
and Separate Shares of Mandatory Convertible Preferred Stock of the Final Remarketing no later than October 20, 2023 (each, a “Notice of a Final Remarketing”) (and the Company shall also provide a copy of such notice to the
Depositary to the Custodial Agent, the Collateral Agent and the Purchase Contract Agent). In such notice, the Company shall set forth: the dates of the Final Remarketing Period; the applicable procedures for holders of Separate Shares of Mandatory
Convertible Preferred Stock to participate in the Final Remarketing; the applicable procedures for Holders of Corporate Units to create Treasury Units or Cash Settled Units; the applicable procedures for Holders of Treasury Units to recreate
Corporate Units; the applicable procedures for Holders of Corporate Units to effect Early Settlement with respect to their Purchase Contracts; that, following a Remarketing Failure, no shares of Common Stock will be delivered upon automatic
conversion of the shares of the Mandatory Convertible Preferred Stock that remain outstanding following the Purchase Contract Settlement Date and each such share of Mandatory Convertible Preferred Stock will be automatically transferred to the
Company on or around March 1, 2024 without any payment of cash or shares of Common Stock thereon; the applicable procedures for Holders of Treasury Units or Cash Settled Units to recreate Corporate Units following the Final Remarketing Period
in the case of a Remarketing Failure in order for their Separate Shares of Mandatory Convertible Preferred Stock to be automatically delivered to the Company in satisfaction of such Holder’s obligations under the related Purchase Contracts, as
described in Section 5.02(b)(viii) below; and any other applicable procedures, including the procedures that must be followed by a holder of Corporate Units in the case of an Unsuccessful Final Remarketing if such Holder
wishes not to have the Mandatory Convertible Preferred Stock underlying its Applicable Ownership Interests in Mandatory Convertible Preferred Stock automatically delivered to the Company in satisfaction of such Holder’s obligations under the
related Purchase Contracts, as described in Section 5.02(b)(viii) below. 
  

  
 59 

 (iii) The Purchase Contract Agent, after receipt of and based on the notices
specified in Section 5.02(a)(iii) (which shall be delivered similarly in respect of the Final Remarketing), shall notify the Remarketing Agent(s) in writing, promptly after 4:00 p.m., New York City time on the Business Day immediately preceding
the first day of the Final Remarketing Period, of the aggregate number of shares of Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock that are to be remarketed, and
the Custodial Agent shall notify in writing the Remarketing Agent(s) of the aggregate number of Separate Shares of Mandatory Convertible Preferred Stock (if any) to be remarketed pursuant to Section 5.02(d) below. Pursuant
to, and subject to the terms of, the Remarketing Agreement, upon receipt of such notices from the Purchase Contract Agent and the Custodial Agent, in each case, as set forth in this Section 5.02(b)(iii), the Remarketing Agent(s) will use its
reasonable best efforts to remarket such shares of Mandatory Convertible Preferred Stock. The Company shall use commercially reasonable efforts to cooperate with the Purchase Contract Agent in connection with the Final Remarketing and shall notify
the Purchase Contract Agent in writing promptly upon becoming aware of the expected Remarketing Date in connection with the Final Remarketing. 

(iv) The Company may postpone the Final Remarketing in its absolute discretion on any day prior to the last Business Day of the
Final Remarketing Period. The Company will promptly furnish notice of any such postponement to the Purchase Contract Agent and the Depositary and shall request that the Depositary notify the Depositary Participants holding Corporate Units, Treasury
Units and Separate Shares of Mandatory Convertible Preferred Stock 
 (v) If the Remarketing Agent(s) is able to remarket
such Mandatory Convertible Preferred Stock and the Separate Shares of Mandatory Convertible Preferred Stock (if any) for at least the applicable Remarketing Price in any Final Remarketing in accordance with the Remarketing Agreement (a
“Successful Final Remarketing”), the Company shall notify the Collateral Agent and the Custodial Agent in writing thereof, and the Collateral Agent shall, upon receipt of such written instructions from the Company, cause the
Securities Intermediary to Transfer to the Remarketing Agent(s) the remarketed Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock upon confirmation of deposit to the
Collateral Account of proceeds of such Successful Final Remarketing attributable to such Mandatory Convertible Preferred Stock, and the Custodial Agent shall Transfer the remarketed Separate Shares of Mandatory Convertible Preferred Stock to the
Remarketing Agent(s) upon confirmation of deposit into the Separate Account of proceeds of such Successful Final Remarketing attributable to such Separate Shares of Mandatory Convertible Preferred Stock. Settlement shall occur on the Remarketing

  
 60 

 
Settlement Date. Upon deposit in the Collateral Account of such proceeds attributable to the remarked Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests
in Mandatory Convertible Preferred Stock, the Collateral Agent shall, on the Purchase Contract Settlement Date, in consultation with the Purchase Contract Agent and upon the written direction of the Company, instruct the Securities Intermediary to
remit to the Company a portion of such proceeds equal to $1,000 multiplied by the aggregate number of such shares of Mandatory Convertible Preferred Stock to satisfy in full the Obligations of Holders of the related Corporate Units to pay the
Purchase Price for the shares of Common Stock under the related Purchase Contracts, and promptly remit the balance of such proceeds to the Purchase Contract Agent for payment to the Holders of Corporate Units whose Mandatory Convertible Preferred
Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock were remarketed, whereupon the Purchase Contract Agent shall make such payment on the Remarketing Settlement Date to such Holders pro rata in
accordance with their respective interests. With respect to any Separate Shares of Mandatory Convertible Preferred Stock remarketed, upon receipt of proceeds attributable to the remarketed Separate Shares of Mandatory Convertible Preferred Stock,
the Custodial Agent shall remit such proceeds of the Successful Final Remarketing received from the Remarketing Agent(s) pro rata to holders of such Separate Shares of Mandatory Convertible Preferred Stock on the Remarketing Settlement Date
in accordance with the instructions provided by such holders in the form of Exhibit M. 
 (vi) Following the
occurrence of a Successful Final Remarketing where the Remarketing Settlement Date occurs prior to the Purchase Contract Settlement Date, a portion of the proceeds from the Successful Final Remarketing equal to $1,000 multiplied by the
aggregate number of shares of Mandatory Convertible Preferred Stock underlying Corporate Units that were remarketed will be substituted as Collateral for the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock and will be
held by the Collateral Agent in accordance with the terms hereof to secure the Obligation of each Holder of Corporate Units, and the Holders of Corporate Units and the Collateral Agent shall have such respective rights, obligations and security
interests with respect to such Cash as the Holder of Corporate Units and the Collateral Agent had in respect of the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, subject to the Pledge thereof. Any reference in this
Agreement or the Certificates to the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock shall thereupon be deemed to be a reference to such amount of Cash. The Company may cause to be made in any Corporate Units
Certificates thereafter to be issued such change in phraseology and form (but not in substance) as may be appropriate to reflect the substitution of such Cash for the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock as
Collateral. Neither the Company, the Purchase Contract Agent, the Custodial Agent, the Securities Intermediary nor anyone else shall be required to invest the portion of such Cash pledged to the Company. The remaining proceeds from the Successful
Remarketing of such shares of Mandatory Convertible Preferred Stock underlying Corporate Units that were remarketed shall be remitted to the Collateral Agent for distribution pro rata to such Holders in accordance with their respective
interests pursuant to instructions provided by the Remarketing Agent to the Collateral Agent.

attributable to the remarketed Separate Shares of Mandatory Convertible Preferred Stock to the Custodial Agent for the benefit of the holders of Separate Shares of Mandatory Convertible Preferred Stock that had their Mandatory Convertible Preferred
Stock remarketed.

the Mandatory Convertible Preferred Stock during the Final Remarketing Period at a price equal to or greater than the applicable Remarketing Price or (2) the Final Remarketing has not occurred on or prior to the last day of the Final
Remarketing Period, or the Remarketing Settlement Date has not occurred as set forth in the Remarketing Agreement, because a condition precedent set forth in the Remarketing Agreement is not fulfilled or otherwise, the Remarketing will be deemed to
have been unsuccessful (an “Unsuccessful Final Remarketing”). The Company shall cause a notice of the Unsuccessful Final Remarketing to be provided in writing to the Custodial Agent, the Collateral Agent and the Purchase Contract
Agent and to be published before the open of business on the Business Day immediately following the last date of the Final Remarketing Period. This notice shall be validly published by making a timely release to any appropriate news agency,
including, without limitation, Bloomberg Business News and the Dow Jones News Service. The Company shall similarly cause a notice of a Successful Final Remarketing to be provided in writing to the Custodial Agent, the Collateral Agent and the
Purchase Contract Agent and to be published before the open of business on the Business Day immediately following the date of such Successful Final Remarketing. 

Following an Unsuccessful Final Remarketing, on December 1, 2023, (A) the Company shall pay each Holder all accrued and unpaid Contract Adjustment
Payments to, but excluding, the December 1, 2023 Contract Adjustment Payment Date, and (B) immediately following such payments (to the extent applicable), as of the Purchase Contract Settlement Date, each Holder of any Pledged Applicable

 62 

 
Account by certified or cashier’s check or wire transfer in immediately available funds payable to or upon the order of the Securities Intermediary (which settlement may only be effected in
integral multiples of 10 Corporate Units), shall be deemed to have automatically delivered the shares of Mandatory Convertible Preferred Stock underlying such Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock in full
satisfaction of such Holder’s obligation to pay the aggregate Purchase Price for the shares of Common Stock to be issued under the related Purchase Contracts. Following such automatic delivery, each such Holder’s Obligations, including to
pay the Purchase Price for the shares of Common Stock, will be deemed to be satisfied in full, and the Collateral Agent shall, upon receipt of written instructions from the Company, cause the Securities Intermediary to release the Mandatory
Convertible Preferred Stock underlying such Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock from the Collateral Account and shall promptly transfer such shares of Mandatory Convertible Preferred Stock to the Company.

 Upon (x) receipt by the Collateral Agent of the direction and instruction from the Purchase Contract Agent in substantially the form of
Exhibit Q hereto promptly after the receipt by the Purchase Contract Agent of a notice from a Holder of Corporate Units that such Holders have elected, in accordance with the first sentence of the immediately preceding
paragraph, to settle the related Purchase Contract with separate cash, and (y) payment by such Holder to the Securities Intermediary of the Purchase Price in accordance with the first sentence of the immediately preceding paragraph, in lieu of
the automatic delivery described in such sentence, the Securities Intermediary shall give the Purchase Contract Agent and the Collateral Agent notice of the receipt of such payment in substantially the form of Exhibit R
hereto and the Collateral Agent shall, and is hereby authorized to, or to cause the Securities Intermediary to (X) deposit the separate cash received from such Holder to the Collateral Account and, if the Company so requests and the Collateral
Agent and Securities Intermediary consent thereto, invest such separate cash received in Permitted Investments, (Y) promptly release from the Pledge the Mandatory Convertible Preferred Stock underlying the Applicable Ownership Interests in
Mandatory Convertible Preferred Stock related to the Corporate Units as to which such Holder has paid such separate cash and (Z) promptly Transfer all such shares of Mandatory Convertible Preferred Stock to the Purchase Contract Agent for
distribution to such Holder as instructed by such Holder to the Purchase Contract Agent in accordance with the terms provided for herein, in each case, free and clear of the Pledge created hereby, whereupon the Purchase Contract Agent shall Transfer
such shares of Mandatory Convertible Preferred Stock in accordance with written instructions provided by the Holder thereof or, if no such instructions are given to the Purchase Contract Agent by the Holder, the Purchase Contract Agent shall hold
such shares of Mandatory Convertible Preferred Stock in the name of the Purchase Contract Agent or its nominee in trust for the benefit of such Holder until the expiration of the time period specified in the relevant abandoned property laws of the
state where such shares of Mandatory Convertible Preferred Stock are held, after which time such shares of Mandatory Convertible Preferred Stock shall be delivered to the Company on request of the Company contained in an Officer’s Certificate.
On the Purchase Contract Settlement Date, the Collateral Agent shall, and is hereby authorized to, (A) instruct the Securities Intermediary to remit to the Company the separate cash amount or such portion of the proceeds of such Permitted
Investments as is equal to the aggregate Purchase Price under all Purchase Contracts in respect of which separate cash has been paid as provided in this Section 5.02(b)(viii), as the case may be, to the Company, and
(B) release any amounts in excess of the aggregate Purchase Price to the Purchase Contract Agent for distribution to the Holders who have paid such separate cash pro rata in proportion to the amount paid by such Holders under this
Section 5.02(b)(viii), as adjusted to reflect the period of time that each such Holder’s cash was invested in such Permitted Investments. 

  
 63 

 Following an Unsuccessful Final Remarketing, as of the Purchase Contract Settlement Date, each Holder of
Treasury Units shall be deemed to have elected to apply a portion of the Cash constituting such Holder’s Pro Rata Portions of the Treasury Unit Collateral equal to the aggregate Purchase Price for the shares of Common Stock to be issued under
the related Purchase Contracts to satisfy such Holder’s obligation to pay such aggregate Purchase Price in full satisfaction of such Holder’s Obligations under such Purchase Contracts. Following such application, each such Holder’s
Obligations, including to pay the Purchase Price for the shares of Common Stock, will be deemed to be satisfied in full, and the Collateral Agent shall, upon receipt of written instructions from the Company, cause the Securities Intermediary to
release such Cash from the Collateral Account and shall promptly transfer such Cash to the Company. Thereafter, (i) the Collateral Agent shall promptly remit the remaining Cash constituting the Holder’s Pro Rata Portions of the Treasury
Unit Collateral in excess of the aggregate Purchase Price for the shares of Common Stock to be issued under such Purchase Contracts to the Purchase Contract Agent for payment to the Holder of the Treasury Units to which such Pro Rata Portions of the
Treasury Unit Collateral relate and (ii) the Company shall notify the Depositary and provide written instructions to the Depositary for announcement and distribution of such excess payments to the applicable Depositary Participants (with a copy
of such notice and instruction to the Purchase Contract Agent). 
 Following an Unsuccessful Final Remarketing, as of the Purchase Contract Settlement Date,
each Holder of Cash Settled Units shall be deemed to have elected to apply the Cash component of such Holder’s Cash Settled Units to satisfy such Holder’s obligation to pay the aggregate Purchase Price for the shares of Common Stock to be
issued under the related Purchase Contracts in full satisfaction of such Holder’s Obligations under such Purchase Contracts. Following such application, each such Holder’s Obligations, including to pay the Purchase Price for the shares of
Common Stock, will be deemed to be satisfied in full, and the Collateral Agent shall, upon receipt of written instructions from the Company, cause the Securities Intermediary to release such Cash from the Collateral Account and shall promptly
transfer such Cash to the Company. 
 (c) In connection with an Optional Remarketing or the Final Remarketing, the Dividend Rate (as such
term is defined in the Certificate of Designations) on all shares of Mandatory Convertible Preferred Stock (whether or not remarketed) may be increased by the Company to the Increased Dividend Rate and dividends thereafter shall be payable on
March 1, 2024 (or, at the Company’s election in consultation with the Remarketing Agent(s) in connection with a Successful Optional Remarketing, on each of December 1, 2023 and March 1, 2024) when, as and if declared by the Board
of Directors. In addition, pursuant to the terms of the Certificate of Designations, the Minimum Conversion Rate on all shares of Mandatory Convertible Preferred Stock (whether or not remarketed) shall be increased by the Company to the Increased
Minimum Conversion Rate if the Closing Price on the pricing date of a Successful Remarketing is less than or equal to the Initial Price. The Increased Rates shall be fixed rates, subject to adjustment as set forth in this Agreement and the
Certificate of Designations, determined by the Board of Directors after consultation with the Remarketing Agents, as the 

  
 64 

 
rate(s) the Mandatory Convertible Preferred Stock should bear and the terms the Mandatory Convertible Preferred Stock should include in order for the proceeds in connection with such Remarketing
to equal (A) in the case of a Final Remarketing, at least $1,000 multiplied by the number of shares of Mandatory Convertible Preferred Stock being remarketed and (B) in the case of an Optional Remarketing, at least the sum of (1)
100% of the Treasury Portfolio Purchase Price and (2) the Separate Shares Purchase Price. Notwithstanding the foregoing, in no event shall the Increased Minimum Conversion Rate exceed the Maximum Conversion Rate. Neither the Minimum Conversion
Rate nor the Dividend Rate (as such term is defined in the Certificate of Designations) shall be decreased, nor the Maximum Conversion Rate changed, in connection with a Successful Remarketing. These modifications shall become effective if the
Remarketing is successful, without the consent of the Holders, upon the Remarketing Settlement Date. If a Successful Remarketing occurs, the Company will request the Depositary to notify the Depositary Participants holding shares of Mandatory
Convertible Preferred Stock of any Increased Rate and Dividend Payment Date (if applicable) for the Mandatory Convertible Preferred Stock on the Business Day following the date of the Successful Remarketing. 

(d) Prior to 4:00 p.m., New York City time, on the second Business Day immediately preceding an Applicable Remarketing Period, other than
during a Blackout Period, holders of Separate Shares of Mandatory Convertible Preferred Stock may elect to have their Separate Shares of Mandatory Convertible Preferred Stock remarketed in such Remarketing in the same manner as the Mandatory
Convertible Preferred Stock underlying Applicable Ownership Interests in Mandatory Convertible Preferred Stock by delivering their Separate Shares of Mandatory Convertible Preferred Stock along with a notice of this election, substantially in the
form of Exhibit M attached hereto, to the Custodial Agent. After such time, such election shall become an irrevocable election to have such Separate Shares of Mandatory Convertible Preferred Stock remarketed in all
Remarketings to occur in the Applicable Remarketing Period. The Custodial Agent shall hold the Separate Shares of Mandatory Convertible Preferred Stock in an account separate from the collateral account in which the Mandatory Convertible Preferred
Stock underlying Applicable Ownership Interests in Mandatory Convertible Preferred Stock shall be held. Holders electing to have their Separate Shares of Mandatory Convertible Preferred Stock remarketed shall also have the right to withdraw the
election by written notice to the Collateral Agent, substantially in the form of Exhibit N hereto, at any time prior to 4:00 p.m., New York City time, on the second Business Day immediately preceding the first day of the
Applicable Remarketing Period. In the event of a Successful Remarketing, proceeds from the Remarketing attributable to holders of Separate Shares of Mandatory Convertible Preferred Stock that elected to have their Mandatory Convertible Preferred
Stock remarketed (which shall be, for the avoidance of doubt, an amount per share of such Mandatory Convertible Preferred Stock greater than or equal to the applicable Remarketing Price Per Share or $1,000, as the case may be) shall be remitted by
the Remarketing Agent(s) for the benefit of such holders on the applicable Remarketing Settlement Date. 
 (e) For the avoidance of doubt,
the right of each holder of the Mandatory Convertible Preferred Stock underlying the aggregate Applicable Ownership Interests in Mandatory Convertible Preferred Stock that are components of Corporate Units and the Separate Shares of Mandatory
Convertible Preferred Stock, the holders of which have elected to participate in any Remarketing, to have such Mandatory Convertible Preferred Stock remarketed and sold on any Remarketing Date shall be subject to the conditions that (i)(1) the
Remarketing 

  
 65 

 
Agent(s) conducts an Optional Remarketing, or (2) in the case of the Final Remarketing, that no Successful Optional Remarketing has occurred, each pursuant to the terms of this Agreement,
(ii) a Termination Event has not occurred prior to such Remarketing Date, (iii) the Remarketing Agent(s) is able to find a purchaser or purchasers for such Mandatory Convertible Preferred Stock at or above the applicable Remarketing Price
or more based on the Increased Rates, if any, and (iv) such purchaser or purchasers deliver the purchase price therefor to the Remarketing Agent(s) as and when required. 

(f) The Company agrees to use its commercially reasonable efforts to ensure that, if required by applicable law, a Registration Statement,
including a prospectus, under the Securities Act with regard to the full amount of the Mandatory Convertible Preferred Stock to be remarketed in each Remarketing in each case shall be effective with the Securities and Exchange Commission in a form
that may be used by the Remarketing Agent(s) in connection with such Remarketing (unless such registration statement is not required under the applicable laws and regulations that are in effect at that time or unless the Company conducts any
Remarketing in accordance with an exemption under the securities laws). 
 (g) Holders whose shares of Mandatory Convertible Preferred Stock
are remarketed will not be responsible for the payment of any Remarketing Fee. 
 (h) In the case of a Treasury Unit or a Corporate Unit (if
Applicable Ownership Interests in the Treasury Portfolio have replaced the Applicable Ownership Interests in Mandatory Convertible Preferred Stock as a component of such Corporate Unit), if the Pledged Treasury Securities or the appropriate Pledged
Applicable Ownership Interests in the Treasury Portfolio held by the Securities Intermediary mature prior to the Purchase Contract Settlement Date, the principal amount of the Treasury Securities or the appropriate Pledged Applicable Ownership
Interests in the Treasury Portfolio received by the Securities Intermediary shall be placed in the Collateral Account. On the Purchase Contract Settlement Date, an amount equal to the Purchase Price for all related Purchase Contracts shall be
remitted to the Company as payment of such Holder’s Obligations under such Purchase Contracts without receiving any instructions from the Holder. In the event the sum of the Proceeds from the related Pledged Treasury Securities or the related
Pledged Applicable Ownership Interests in the Treasury Portfolio is in excess of the aggregate Purchase Price, (i) the Collateral Agent shall cause the Securities Intermediary to distribute such excess, when received by the Securities
Intermediary, to the Purchase Contract Agent for the benefit of the Holder of the related Treasury Units or Corporate Units, as applicable and (ii) the Company shall notify the Depositary and provide written instructions to the Depositary for
announcement and distribution of such excess payments to the applicable Depositary Participants (with a copy of such notice and instruction to the Purchase Contract Agent). 

(i) The obligations of the Holders to pay the Purchase Price are non-recourse obligations and, except
to the extent satisfied by Early Settlement, Fundamental Change Early Settlement or settlement with separate cash pursuant to Section 5.02(b)(viii) or terminated upon a Termination Event, are payable solely out of the
proceeds of any Collateral pledged to secure the obligations of the Holders, and in no event will Holders be liable for any deficiency between the proceeds of the disposition of Collateral and the Purchase Price. 

  
 66 

 (j) The Company shall not be obligated to issue any shares of Common Stock in respect of a
Purchase Contract or deliver any certificates thereof to the Holder of the related Units unless the Company shall have received, subject to Section 5.02(i), payment for the Common Stock to be purchased thereunder in the
manner herein set forth. 
 Section 5.03. Issuance of Shares of Common Stock. Unless a Termination Event, an Early
Settlement or a Fundamental Change Early Settlement shall have occurred, on the Purchase Contract Settlement Date, upon the Company’s receipt of the aggregate Purchase Price payable on all Outstanding Units in accordance with
Section 5.02, the Company shall issue and deposit with the Purchase Contract Agent, for the benefit of the Holders of the Outstanding Units, one or more certificates representing newly-issued shares of Common Stock
registered in the name of the Purchase Contract Agent (or its nominee) as custodian for the Holders to which the Holders are entitled hereunder; provided, that, in case such Common Stock is to be delivered through the facilities of DTC or
another Depositary, the Company shall cause the transfer agent for the Common Stock to deliver beneficial interests in such Common Stock on behalf of the Purchase Contract Agent through such facilities to the Holders entitled thereto. 

Subject to the foregoing, following book-entry transfer of a Unit or upon presentation and surrender of a Certificate, if in certificated form, to the
Purchase Contract Agent on or after the Purchase Contract Settlement Date, Early Settlement Date or the Fundamental Change Early Settlement Date, as the case may be, together with settlement instructions thereon duly completed and executed, the
Holder of the relevant Unit shall on the applicable settlement date (or, if later, the date of such book-entry transfer of the Unit or such surrender of the Certificate shall be entitled to receive forthwith in exchange therefor book-entry transfer
of beneficial interests in, or a certificate representing that number of newly-issued whole shares of Common Stock which such Holder is entitled to receive pursuant to the provisions of this Article 5 (after taking into
account all Units then held by such Holder), together with cash in lieu of fractional shares as provided in Section 5.07 and, in the case of a settlement on the Purchase Contract Settlement Date, any dividends or distributions with respect to
such shares of Common Stock for which a record date and payment date occurred on or after the Purchase Contract Settlement Date, and the number of Units represented by the Global Certificate shall be appropriately reduced in accordance with
Applicable Procedures and standing arrangements between the Depositary and the Purchase Contract Agent or the Company, or the Certificate so surrendered shall forthwith be cancelled, as the case may be. Such shares shall be registered in the name
of, or book-entry interests therein shall be transferred to, the Holder or the Holder’s designee as specified in the settlement instructions set forth on the reverse of the Certificate provided by the Holder to the Purchase Contract Agent. If
any shares of Common Stock issued in respect of a Purchase Contract are to be registered in the name of, or beneficial interests therein are transferred to, a Person other than the Person in whose name the Certificate evidencing such Purchase
Contract is registered (but excluding any Depositary or nominee thereof) or the beneficial owner, no such registration or transfer shall be made unless and until the Person requesting such registration or transfer has paid the Company the amount of
any transfer and other taxes (including any applicable stamp taxes) required by reason of such registration in a name other than that of, or transfer to a Person other than, the registered Holder of the Certificate evidencing such Purchase Contract
or beneficial owner thereof or has established to the satisfaction of the Company that such tax either has been paid or is not payable. 

  
 67 

 Section 5.04. Fundamental Change Early Settlement. 

(a) If a Fundamental Change occurs prior to the Purchase Contract Settlement Date, then, following the occurrence of a Fundamental Change, each
Holder of a Unit, subject to the conditions described in this Section 5.04, shall have the right (a “Fundamental Change Early Settlement Right”) to settle (a “Fundamental Change Early
Settlement”) its Purchase Contract early on the Fundamental Change Early Settlement Date at the Settlement Rate determined as if the Applicable Market Value equaled the Stock Price, plus an additional number of shares of Common Stock
(such additional number, the “Make-Whole Shares”), subject to adjustment under Section 5.11, and receive payment of Cash in lieu of any fraction of a share, as provided in
Section 5.07; provided that no Fundamental Change Early Settlement will be permitted pursuant to this Section 5.04(a) unless, at the time such Fundamental Change Early Settlement is
effected, there is an effective Registration Statement with respect to any shares of Common Stock to be issued and delivered in connection with such Fundamental Change Early Settlement, if such a Registration Statement is required (in the view of
counsel, which need not be in the form of a written opinion, for the Company) under the Securities Act. If such a Registration Statement is so required, the Company covenants and agrees to use its commercially reasonable efforts to (x) have in
effect a Registration Statement covering the Common Stock and other securities, if any, to be delivered in respect of the Purchase Contracts being settled and (y) provide a Prospectus in connection therewith, in each case in a form that may be
used in connection with such Fundamental Change Early Settlement (it being understood that if there is a material business transaction or development that has not yet been publicly disclosed, the Company will not be required to provide such a
Prospectus, and the right to effect Fundamental Change Early Settlement will not be available, until the Company has publicly disclosed such transaction or development, provided that the Company will use its commercially reasonable efforts to
make such disclosure as soon as it is commercially reasonable to do so). 
 In the event that a Holder seeks to exercise its Fundamental Change Early
Settlement Right and a Registration Statement is required to be effective in connection with the exercise of such right but no such Registration Statement is then effective, the Holder’s exercise of such right shall be void unless and until
such a Registration Statement shall be effective, but such Holder shall receive consideration calculated as described in this Section 5.04(a) when such Registration Statement becomes effective; provided that the
Fundamental Change Early Settlement Date shall not be so postponed beyond the Purchase Contract Settlement Date. If, but for the proviso in the immediately preceding sentence, the Fundamental Change Early Settlement Date would occur on or
after the Purchase Contract Settlement Date, the Company shall deliver to any Holder on the Purchase Contract Settlement Date the applicable number of Make-Whole Shares in addition to a number of shares of Common Stock equal to the Settlement Rate,
determined as if the Applicable Market Value were equal to the Stock Price. 
 If a Holder elects a Fundamental Change Early Settlement of some or all of
its Purchase Contracts, such Holder shall be entitled to receive, on the Fundamental Change Early Settlement Date, the aggregate amount of any accrued and unpaid Contract Adjustment Payments (including deferred Contract Adjustment Payments and
Compounded Contract Adjustment Payments thereon), with respect to such Purchase Contracts to, but excluding, the Fundamental Change Settlement Date (except when the Fundamental Change Early Settlement Date falls after any Record Date and prior to
the next succeeding Contract Adjustment Payment Date, in which case 

  
 68 

 
Contract Adjustment Payments shall be payable to the Person in whose name a Certificate is registered at the close of business on such Record Date relating to the next succeeding Contract
Adjustment Payment Date), payable in the manner set forth in Section 5.09(e)(i). The Company shall pay such amount as a credit against the amount otherwise payable by such Holder to effect such Fundamental Change Early
Settlement. 
 The Company shall provide each Holder and the Purchase Contract Agent with written notice of a Fundamental Change as soon as practicable
after becoming aware of the occurrence of such Fundamental Change but in any after no later than five Business Days after the Effective Date of such Fundamental Change, which shall specify: 

(i) the date on which such Fundamental Change Early Settlement shall occur (such date, the “Fundamental Change Early
Settlement Date”) which shall be at least 10 Business Days after the Effective Date of such Fundamental Change but, subject to the foregoing, no later than the earlier of (x) 20 Business Days after the Effective Date of such Fundamental
Change and (y) one Business Day prior to (i) the first day of the commencement of an Optional Remarketing Period, or (ii) if the Company has not specified an Optional Remarketing Period or the Optional Remarketing is not successful,
the first day of the commencement of the Final Remarketing Period or, if the Final Remarketing is not successful, the Purchase Contract Settlement Date; 

(ii) the date by which Holders must exercise the Fundamental Change Early Settlement Right; 

(iii) the applicable Settlement Rate and number of Make-Whole Shares; 

(iv) the amount and kind (per share of Common Stock) of the Cash, securities and other consideration receivable by the Holder
upon Fundamental Change Early Settlement; and 
 (v) the amount of accrued and unpaid Contract Adjustment Payments (including
any deferred Contract Adjustment Payments and Compounded Contract Adjustment Payments thereon), if any, that will be paid upon settlement to Holders exercising the Fundamental Change Early Settlement Right and the method by which the Company will
pay such Contract Adjustment Payments. 
 Notwithstanding the foregoing, if the Final Remarketing Period begins less than ten Business Days following the
occurrence of a Fundamental Change, the notice will specify the Purchase Contract Settlement Date as the Fundamental Change Early Settlement Date. 

Corporate Units Holders and Treasury Units Holders may only effect Fundamental Change Early Settlement pursuant to this
Section 5.04(a) in integral multiples of 10 Corporate Units or Treasury Units, as the case may be. Other than the provisions relating to timing of notice and settlement, which shall be as set forth above, the provisions of
Section 5.01(a) shall apply with respect to a Fundamental Change Early Settlement pursuant to this Section 5.04(a). 

  
 69 

 In order to exercise the right to effect a Fundamental Change Early Settlement with respect to any Purchase
Contracts, the Holder of the Certificate evidencing Units shall deliver to the Purchase Contract Agent at the Corporate Trust Office, during the period beginning on the date the Company delivers written notice that a Fundamental Change has occurred
and ending at 4:00 p.m., New York City time, on the second Business Day immediately preceding the Fundamental Change Early Settlement Date, such Certificate evidencing its Corporate Units or Treasury Units if they are held in certificated form, duly
endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds) in an amount equal to the aggregate
Purchase Price corresponding to the number of Purchase Contracts with respect to which the Holder has elected to effect Fundamental Change Early Settlement. In the event that Units are held by or through DTC or another Depositary, the exercise of
the right to effect Fundamental Change Early Settlement shall occur in conformity with the Applicable Procedures and the standing arrangements between DTC or such Depositary and the Purchase Contract Agent or the Company. 

Upon receipt of such Certificate and payment of such funds, the Purchase Contract Agent shall pay the Company from such funds the related Purchase Price
pursuant to the terms of the related Purchase Contracts, the Company shall promptly notify the Purchase Contract Agent in writing of its receipt of the related Purchase Price, and upon receipt of such written confirmation, the Purchase Contract
Agent shall then provide to the Collateral Agent a notice in writing, substantially in the form of Exhibit O hereto, that all the conditions necessary for a Fundamental Change Early Settlement by such Holder have been satisfied pursuant to
which the Purchase Contract Agent has received from such Holder, and paid to the Company as confirmed in writing by the Company, the related Purchase Price. 

Upon receipt by the Collateral Agent of the written notice from the Purchase Contract Agent set forth in the immediately preceding paragraph, the Collateral
Agent shall release from the Pledge, (1) the Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock or the Pledged Applicable Ownership Interests in the Treasury
Portfolio or (2) the applicable Treasury Securities corresponding to the number of Purchase Contracts as to which such Holder of Treasury Units has elected to effect a Fundamental Change Early Settlement, and shall instruct the Securities
Intermediary to Transfer all such Pledged Applicable Ownership Interests in the Treasury Portfolio or Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock or applicable
Proceeds of the Treasury Securities, as the case may be, to the Purchase Contract Agent or Transfer Agent, as applicable, for distribution to such Holder in accordance with the terms provided for herein, in each case free and clear of the Pledge
created hereby. 
 If a Holder properly effects an effective Fundamental Change Early Settlement in accordance with the provisions of this
Section 5.04(a), the Company will deliver (or will cause and instruct the Purchase Contract Agent in writing to deliver) to the Holder on the Fundamental Change Early Settlement Date for each Purchase Contract with respect
to which such Holder has elected Fundamental Change Early Settlement: 
 (i) a number of shares of Common Stock (or Exchange
Property Units, if applicable) equal to the Settlement Rate determined as if the Applicable Market Value equaled the Stock Price plus the Make-Whole Shares, if any; 

  
 70 

 (ii) the shares of Mandatory Convertible Preferred Stock, the Applicable
Ownership Interests in the Treasury Portfolio or applicable Proceeds of the Treasury Securities underlying the Corporate Units or Treasury Units, as the case may be, with respect to which the Holder is effecting a Fundamental Change Early
Settlement, free and clear of the Pledge created hereby; and 
 (iii) if so required under the Securities Act, a Prospectus
as contemplated by this Section 5.04(a). 
 For the avoidance of doubt, any accrued and unpaid Contract Adjustment Payments
(including any deferred Contract Adjustment Payments and Compounded Contract Adjustment Payments thereon) with respect to such Purchase Contract to, but excluding, the Fundamental Change Early Settlement Date shall be due and payable by the Company
on the Fundamental Change Early Settlement Date for such Purchase Contract, subject to Section 5.09(e)(i). 
 The Corporate Units
or the Treasury Units of the Holders who do not elect Fundamental Change Early Settlement in accordance with the foregoing will continue to remain outstanding and be subject to settlement on the Purchase Contract Settlement Date in accordance with
the terms hereof. In the event that Fundamental Change Early Settlement is effected with respect to Purchase Contracts underlying less than all the Units evidenced by a Certificate, upon such Fundamental Change Early Settlement, the Company shall
execute and upon receipt of an Issuer Order, the Purchase Contract Agent shall execute on behalf of the Holder as its attorney-in-fact, authenticate and deliver to the
Holder thereof, at the expense of the Company, a Certificate evidencing the Units as to which Fundamental Change Early Settlement was not effected. 

(b) The number of Make-Whole Shares per Purchase Contract deliverable upon a Fundamental Change Early Settlement shall be calculated by the
Company and shall be determined by reference to the table below, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”) and the Stock Price in the such Fundamental Change. The
“Stock Price” shall be: 
 (i) in the case of a Fundamental Change described in clause (ii) of the
definition thereof where the holders of the Common Stock receive only Cash in the Fundamental Change, the Cash amount paid per share of the Common Stock; and 

(ii) in all other cases, the average of the Closing Prices of the Common Stock for the 10 consecutive Trading Days immediately
prior to but not including the Effective Date. 
 The Stock Prices set forth in the first row of the table (i.e., the column headers) shall be adjusted upon
the occurrence of any event requiring an anti-dilution adjustment to the Maximum Settlement Rate pursuant to Section 5.11 in a manner inversely proportional to the adjustments to the Maximum Settlement Rate. Each of the
Make-Whole Share amounts in the table will be subject to adjustment in the same manner and at the same time as the Maximum Settlement Rate as set forth in Section 5.11.

 The actual Stock Price and Effective Date applicable to a Fundamental Change may not be set forth on the table, in which case:

 (i) if the actual Stock Price is between two Stock Prices on the table or the actual Effective Date is between two
Effective Dates on the table, the amount of Make-Whole Shares shall be determined by a straight-line interpolation between the Make-Whole Share amounts set forth for the two Stock Prices and the two Effective Dates on the table based on a 365-day year, as applicable; 
 (ii) if the Stock Price exceeds $60.00 per share (subject
to adjustment in the same manner as the Stock Prices set forth in the table above), then the Make-Whole Share amount shall be zero; and 

(iii) if the Stock Price is less than $10.00 per share (subject to adjustment in the same manner as the Stock Prices set forth
in the table above) (the “Minimum Stock Price”), then the Make-Whole Share amount shall be determined as if the Stock Price equaled the Minimum Stock Price, using straight-line interpolation, as described above, if the actual
Effective Date is between two Effective Dates on the table. 
 Notwithstanding the foregoing, in no event will the total number of shares of Common Stock
issuable upon settlement of a Purchase Contract exceed 5.0843 shares per Purchase Contract (subject to adjustment in the same manner and at the same time as the Maximum Settlement Rate as set forth in Section 5.11). 

(c) All calculations and determinations pursuant to this Article 5 shall be made by the Company or its agent in good
faith, and the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary shall have no responsibility for making, verifying or confirming such calculations or determinations or otherwise with respect to such
calculations or determinations under this Agreement or otherwise, and may conclusively presume that such calculations and determinations are correct and conform to the requirements of this Agreement. 

Section 5.05. Termination Event; Notice. The Purchase Contracts and all obligations and rights of the Company and the
Holders thereunder, including, without limitation, the rights of the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments (including any deferred Contract Adjustment Payments and Compounded Contract Adjustment
Payments thereon), and the rights and obligations of Holders to purchase Common Stock, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Purchase Contract Agent or the Company, if, prior
to or on the Purchase Contract Settlement Date, a Termination Event shall have occurred. 

  
 72 

 Upon and after the occurrence of a Termination Event, the Units shall thereafter represent the right to
receive the shares of Mandatory Convertible Preferred Stock underlying the Applicable Ownership Interests in Mandatory Convertible Preferred Stock, the Treasury Securities, the Cash or the Applicable Ownership Interests in the Treasury Portfolio, as
the case may be, forming part of such Units, and any other Collateral, in each case, in accordance with the provisions of Section 3.16(a) hereof. Upon the occurrence of a Termination Event, (i) the Company shall
promptly but in no event later than two Business Days thereafter give written notice to the Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register and (ii) the Collateral Agent
shall, in accordance with Section 3.16(a) hereof, and the instructions provided for in the aforementioned notice from the Company, release the shares of Mandatory Convertible Preferred Stock underlying the Pledged
Applicable Ownership Interests in Mandatory Convertible Preferred Stock or the Applicable Ownership Interests in the Treasury Portfolio forming a part of each Corporate Unit, the Pro Rata Portion of the Treasury Unit Collateral forming a part of
each Treasury Unit or the Cash forming a part of each Cash Settled Unit, as the case may be, and any other Collateral from the Pledge. 

Section 5.06. Early Settlement. (a) Subject to and upon compliance with the provisions of this
Section 5.06(a), at the option of the Holder thereof, at any time prior to 4:00 p.m., New York City Time, on the Scheduled Trading Day immediately preceding the first day of the Market Value Averaging Period, other than
during a Blackout Period, Purchase Contracts underlying Units may be settled early (“Early Settlement”); provided that no Early Settlement will be permitted pursuant to this Section 5.06(a) unless,
at the time such Early Settlement is effected, there is an effective Registration Statement with respect to the shares of Common Stock and other securities, if any, to be issued and delivered in connection with such Early Settlement, if such a
Registration Statement is required (in the view of counsel, which need not be in the form of a written opinion, for the Company) under the Securities Act. If such a Registration Statement is so required, the Company (A) shall, promptly after
the date on which the Company is notified by the Purchase Contract Agent that the Holder has attempted an Early Settlement, so notify such Holder, and (B) covenants and agrees to use its commercially reasonable efforts to (i) have in
effect a Registration Statement covering those shares of Common Stock and other securities, if any, to be delivered in respect of the Purchase Contracts being settled and (ii) provide a Prospectus in connection therewith, in each case in a form
that may be used in connection with such Early Settlement (it being understood that if there is a material business transaction or development that has not yet been publicly disclosed, the Company will not be required to provide such a Prospectus,
and the right to effect Early Settlement will not be available, until the Company has publicly disclosed such transaction or development, provided that the Company will use its commercially reasonable efforts to make such disclosure as soon
as it is commercially reasonable to do so). 
 (b) In order to exercise the right to effect Early Settlement with respect to any Purchase
Contracts, the Holder of the Certificate evidencing Units (in the case of Certificates in definitive certificated form) shall deliver, at any time prior to 4:00 p.m., New York City time, on the Scheduled Trading Day immediately preceding the first
day of the Market Value Averaging Period, other than during a Blackout Period, such Certificate to the Purchase Contract Agent at 

  
 73 

 
the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment
(payable to the Company in Cash in immediately available funds) in an amount (the “Early Settlement Amount”) equal to the sum of: 

(i) the aggregate Purchase Price for the number of Purchase Contracts with respect to which the Holder has elected to effect
Early Settlement, plus, 
 (ii) if the Early Settlement Date with respect to any Purchase Contracts occurs during the
period from the close of business on any Record Date to the open of business on the related Contract Adjustment Payment Date, an amount equal to the Contract Adjustment Payments payable on such Contract Adjustment Payment Date with respect to such
Purchase Contracts, unless the Company has elected to defer the Contract Adjustment Payments which would otherwise be payable on such Contract Adjustment Payment Date. 

In the case of Book-Entry Interests, each Beneficial Owner electing Early Settlement must deliver the Early Settlement Amount to the Purchase Contract Agent
along with a facsimile of the Election to Settle Early form duly completed, make book-entry transfer of such Book-Entry Interests and comply with the applicable procedures of the Depositary by the applicable time set forth above in this
Section 5.06(a). In addition, so long as the Units are evidenced by one or more Global Certificates deposited with the Depositary, procedures for Early Settlement will also be governed by the Applicable Procedures and the
standing arrangements between the Depositary and the Purchase Contract Agent or the Company. 
 Except as provided in
Section 5.09(d), no payment shall be made upon Early Settlement of any Purchase Contract on account of any Contract Adjustment Payments (other than deferred Contract Adjustment Payments and any Compounded Contract
Adjustment Payments thereon) accrued on such Purchase Contract or on account of any dividends on the Common Stock issued upon such Early Settlement. If the foregoing requirements are first satisfied with respect to Purchase Contracts underlying any
Units at or prior to 4:00 p.m., New York City time, on a Business Day, such day shall be the “Early Settlement Date” with respect to such Units and if such requirements are first satisfied at or after 4:00 p.m., New York City time,
on a Business Day or on a day that is not a Business Day, the Early Settlement Date with respect to such Units shall be the next succeeding Business Day. 

Upon the receipt of (i) such Certificate, (ii) a duly completed Election to Settle Early form and (iii) the Early Settlement Amount from the
Holder, the Purchase Contract Agent shall pay to the Company such Early Settlement Amount, the receipt of which payment the Company shall promptly confirm in writing. Upon written confirmation of such payment by the Company to the Purchase Contract
Agent, the Purchase Contract Agent shall then provide to the Collateral Agent a notice in writing, substantially in the form of Exhibit O hereto, that (A) such Holder has elected to effect an Early Settlement, and
(B) the Purchase Contract Agent has received from such Holder, and paid to the Company as confirmed in writing by the Company, the related Purchase Price. 

  
 74 

 Upon receipt by the Collateral Agent of the written notice from the Purchase Contract Agent set forth in the
preceding paragraph, within two Business Days following the Early Settlement Date, the Collateral Agent shall release from the Pledge, (1) in the case of a Holder of Corporate Units, the shares of Mandatory Convertible Preferred Stock
underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock, or the Pledged Applicable Ownership Interests in the Treasury Portfolio, as the case may be, relating to the Purchase Contracts to which Early Settlement
is effected, or (2) in the case of a Holder of Treasury Units, the Proceeds of the applicable Pro Rata Portions of the Treasury Securities corresponding to the number of Purchase Contracts as to which such Holder has elected to effect Early
Settlement, and shall instruct the Securities Intermediary to Transfer all such Pledged Applicable Ownership Interests in the Treasury Portfolio or shares of Mandatory Convertible Preferred Stock underlying such Pledged Applicable Ownership
Interests in Mandatory Convertible Preferred Stock or Proceeds of the Treasury Securities, as the case may be, to the Purchase Contract Agent for distribution to such Holder in accordance with the terms provided for herein, in each case free and
clear of the Pledge created hereby. 
 Holders of Corporate Units and Treasury Units may only effect Early Settlement pursuant to this
Section 5.06(a) in integral multiples of 10 Corporate Units or 10 Treasury Units, as the case may be. 
 Upon Early Settlement of
the Purchase Contracts, the rights of the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments (including any deferred Contract Adjustment Payments and Compounded Contract Adjustment Payments thereon) with
respect to such Purchase Contracts shall immediately and automatically terminate, except as provided in Section 5.09(d). 

(c) Upon Early Settlement of Purchase Contracts by a Holder of the related Units, on the applicable settlement date, the Company shall issue,
and the Holder shall be entitled to receive, and the Company will deliver to the transfer agent for the Common Stock for delivery to such Holder, a number of shares of Common Stock equal to 85% of the Settlement Rate calculated as set forth in
Section 5.01(a) for each Purchase Contract as to which Early Settlement is effected, as if the Applicable Market Value for such purpose were equal to the average of the Daily VWAPs of the Common Stock during the Early
Settlement Averaging Period (subject to Section 5.12). 
 (d) No later than the close of business on the second
Business Day after the last Trading Day of the Early Settlement Averaging Period, the Company shall cause the shares of Common Stock issuable upon Early Settlement of Purchase Contracts to be issued and delivered, accompanied with a payment in
respect of the aggregate deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon), if any, through the Contract Adjustment Payment Date immediately preceding such Early Settlement Date, payable as set forth
in Section 5.09(e)(i). 
 (e) Upon Early Settlement of any Purchase Contracts, and subject to receipt of shares of
Common Stock from the Company and the Mandatory Convertible Preferred Stock, the Applicable Ownership Interests in the Treasury Portfolio or the applicable Proceeds of the Treasury Securities, as the case may be, from the Securities Intermediary, as
applicable, the Purchase Contract Agent shall on the applicable settlement date, in accordance with the instructions provided by the Holder thereof on the applicable form of Election to Settle Early on the reverse of the Certificate evidencing the
related Units: 

  
 75 

 (i) transfer to the Holder (or its designee) the Mandatory Convertible
Preferred Stock, the Applicable Ownership Interests in the Treasury Portfolio or the applicable Proceeds of the Treasury Securities related to such Units, as the case may be, 

(ii) deliver to the Holder (or its designee) a certificate or certificates for the full number of shares of Common Stock
issuable upon such Early Settlement, and 
 (iii) if so required under the Securities Act, deliver a Prospectus for the
shares of Common Stock issuable upon such Early Settlement as contemplated by Section 5.06(a). 
 (f) In the event
that Early Settlement is effected with respect to Purchase Contracts underlying less than all the Units evidenced by a Certificate, upon such Early Settlement the Company shall execute and the Purchase Contract Agent shall execute on behalf of the
Holder as its attorney-in-fact, and upon receipt of an Issuer Order, authenticate and deliver to the Holder thereof, at the expense of the Company, a Certificate
evidencing the Units as to which Early Settlement was not effected. 
 Section 5.07. No Fractional Shares. No fractional
shares or scrip representing fractional shares of Common Stock shall be issued or delivered upon settlement on the Purchase Contract Settlement Date, or upon Early Settlement or Fundamental Change Early Settlement of any Purchase Contracts. Instead
of any fractional share of Common Stock that would otherwise be deliverable upon settlement on the Purchase Contract Settlement Date or upon Early Settlement or Fundamental Change Early Settlement of any Purchase Contracts, the Company, through the
Purchase Contract Agent, shall make a Cash payment to the Holder in respect of such fractional interest in an amount equal to the percentage of a whole share represented by such fractional share multiplied by the Closing Price of the Common
Stock on the Trading Day immediately preceding the Purchase Contract Settlement Date (or (x) in the case of any Early Settlement, the Closing Price of the Common Stock on the Trading Day immediately preceding the relevant date for delivery of
the shares of Common Stock issuable upon such Early Settlement and (y) in the case of a Fundamental Change Early Settlement, the Closing Price of the Common Stock on the Trading Day immediately preceding the relevant Fundamental Change Early
Settlement Date). If, however, a Holder surrenders for settlement more than one Purchase Contract on the same date, then the number of full shares of Common Stock issuable pursuant to such Purchase Contracts shall be computed based upon the
aggregate number of Purchase Contracts surrendered on such date, or if the Corporate Units are held in global book-entry form, based on such other aggregate number of Purchase Contracts being surrendered by the Holder on the same date as the
Depositary may otherwise require. The Company shall provide the Purchase Contract Agent from time to time with sufficient funds and instructions to permit the Purchase Contract Agent to make all cash payments required by this Section 5.07 in a
timely manner. 

  
 76 

 Section 5.08. Charges and Taxes. The Company will pay all stock transfer
and similar taxes attributable to the initial issuance and delivery of the shares of Common Stock pursuant to the Purchase Contracts; provided, however, that the Company shall not be required to pay any such tax or taxes that may be payable
in respect of any exchange of or substitution for a Certificate evidencing a Unit or any issuance of a share of Common Stock in a name other than that of the registered Holder of a Certificate surrendered in respect of the Units evidenced thereby,
other than in the name of the Purchase Contract Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Certificates unless or until the Person or Persons requesting the transfer or
issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 

Section 5.09. Contract Adjustment Payments. (a) Subject to Section 5.09(d), the Company
shall pay, on each Contract Adjustment Payment Date, the Contract Adjustment Payments payable in respect of each Purchase Contract for the period from and including the immediately preceding Contract Adjustment Payment Date on which Contract
Adjustment Payments were paid (or if none, April 19, 2021) to but excluding such Contract Adjustment Payment Date to the Person in whose name a Certificate is registered at the close of business on the Record Date relating to such Contract
Adjustment Payment Date. Contract Adjustment Payments shall be payable in cash, by delivery of shares of Common Stock or through any combination of cash and shares of Common Stock, as set forth in Section 5.09(e)(i).
Contract Adjustment Payments on Global Certificates payable in cash shall be made by wire transfer of immediately available funds to the Depositary on or prior to 10:00 a.m., New York City time, on the relevant Contract Adjustment Payment Date. If
the book-entry system for the Units has been terminated, Contract Adjustment Payments payable in cash shall be payable at the designated corporate trust office of the Purchase Contract Agent in the contiguous United States maintained for that
purpose on or prior to 10:00 a.m., New York City time, on the relevant Contract Adjustment Payment Date or, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on
the Security Register as of the Record Date, or by wire transfer to the account designated by such Person by a prior written notice to the Purchase Contract Agent, given at least ten calendar days prior to the Contract Adjustment Payment Date.
Contract Adjustment Payments payable for any period will be computed (x) for any full quarterly period on the basis of a 360-day year of twelve 30-day months and
(y) for any period shorter than a full quarterly period, on the basis of a 30-day month and, for any period less than a month, on the basis of the actual number of days elapsed in a 30-day month. The Contract Adjustment Payments will accrue from April 19, 2021. 
 (b) Upon the
occurrence of a Termination Event, the Company’s obligation to pay future Contract Adjustment Payments and any deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon) shall cease. 

(c) Each Certificate delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of (including as a result of
a Collateral Substitution or the recreation of Corporate Units) any other Certificate shall carry the right to accrued and unpaid Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon), which right was carried by
the Purchase Contracts underlying such other Certificates. 
 (d) In the case of any Unit with respect to which Early Settlement or
Fundamental Change Early Settlement of the underlying Purchase Contract (if applicable) is effected on a date that is after any Record Date and on or prior to the open of business on the related Contract Adjustment Payment Date, Contract Adjustment
Payments and deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon) otherwise payable on such Contract Adjustment Payment Date shall be payable on such Contract Adjustment Payment Date notwithstanding such
Early Settlement or Fundamental Change Early Settlement, and such Contract Adjustment Payments and deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon) shall be paid to the Person in whose name the
Certificate evidencing such Unit is registered at the close of business on such Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Unit with respect to which Early Settlement of the
underlying Purchase Contract is effected, Contract Adjustment Payments that would otherwise have accrued after the most recent Contract Adjustment Payment Date with respect to such Purchase Contract shall not be payable. 

  
 77 

 (e) (i) Subject to the limitations described below, the Company may pay any Contract
Adjustment Payment (including Compounded Contract Adjustment Payments thereon or any portion of any Contract Adjustment Payment), whether or not for a current Contract Adjustment Payment Date or in respect of any prior Contract Adjustment Payment
Date, as determined in its sole discretion: 
 (A) in cash; 

(B) by delivery of shares of Common Stock; or 

(C) through any combination of cash and shares of Common Stock. 

(ii) Each Contract Adjustment Payment shall be made in cash, except to the extent the Company timely elects to make all or any
portion of such Contract Adjustment Payment in shares of Common Stock. To the extent the Company does not elect to defer such Contract Adjustment Payment, the Company shall give notice to the Depositary and Holders of any such election and the
portion of such Contract Adjustment Payment that will be made in cash and the portion that will be made in Common Stock no later than eight Scheduled Trading Days prior to the Contract Adjustment Payment Date for such Contract Adjustment Payment.

 (iii) Any shares of Common Stock issued in payment or partial payment of a Contract Adjustment Payment shall be valued for
such purpose at the applicable Five-Day Average Price, multiplied by 97%. 

(iv) No fractional shares of Common Stock shall be delivered by the Company to Holders in payment or partial payment of a
Contract Adjustment Payment. A cash adjustment shall be paid by the Company to each Holder that would otherwise be entitled to receive a fraction of a share of Common Stock based on (x) the Five-Day
Average Price and (y) the aggregate number of Units held by such Holder (or if the Units are held in global book-entry form, based on the applicable procedures of the Depositary for determining such number of Units). 

  
 78 

 (v) To the extent that the Company, in its reasonable judgment, determines
that a Registration Statement is required in connection with the issuance of, or for resales of, Common Stock issued as a Contract Adjustment Payment, including Contract Adjustment Payments paid in connection with a Fundamental Change Early
Settlement, the Company shall, to the extent such a Registration Statement is not currently filed and effective, use its reasonable best efforts to file and maintain the effectiveness of such a Registration Statement until the earlier of such time
as all such shares of Common Stock have been resold thereunder and such time as all such shares are freely tradable under Rule 144 by non-Affiliates of the Company without registration. To the extent
applicable, the Company shall also use its reasonable best efforts to have such shares of Common Stock qualified or registered under applicable state securities laws, if required, and approved for listing on the NYSE (or if the Common Stock is not
then listed on the NYSE, on the principal other U.S. national or regional securities exchange on which the Common Stock is then listed). 

(f) The Contract Adjustment Payments are unsecured and will rank subordinate and junior in right of payment to all of the Company’s
existing and future Indebtedness. 
 Section 5.10. Deferral of Contract Adjustment Payments. 

(a) The Company has the right at any time, and from time to time, to defer payment of all or part of the Contract Adjustment Payments in
respect of each Purchase Contract by extending the period for payment of Contract Adjustment Payments to any subsequent Contract Adjustment Payment Date (an “Extension Period”), but not beyond the Purchase Contract Settlement Date
(or, with respect to Purchase Contracts for which (i) an effective Fundamental Change Early Settlement has occurred, the Fundamental Change Early Settlement Date or (ii) an effective Early Settlement has occurred, the Contract Adjustment
Payment Date immediately preceding the Early Settlement Date). Prior to the expiration of any Extension Period, the Company may further extend such Extension Period to any subsequent Contract Adjustment Payment Date, but not beyond the Purchase
Contract Settlement Date (or any applicable Fundamental Change Early Settlement Date or Contract Adjustment Payment Date immediately preceding the Early Settlement Date, as the case may be). 

If the Company so elects to defer Contract Adjustment Payments, the Company shall pay additional Contract Adjustment Payments on such deferred installments of
Contract Adjustment Payments at the annual rate then in effect for Contract Adjustment Payments, compounding on each succeeding Contract Adjustment Payment Date, to, but excluding, the date such deferred installments are paid in full (the accrued
additional Contract Adjustment Payments thereon, being referred to herein as the “Compounded Contract Adjustment Payments”). The Company may pay any such deferred Contract Adjustment Payments (including Compounded Contract
Adjustment Payments thereon) on any scheduled Contract Adjustment Payment Date to the Holder on the related Record Date, subject to subsection (c) below. 

At the end of each Extension Period, including as the same may be extended as provided above, or, in the event of an effective Early Settlement or Fundamental
Change Early Settlement, on the date shares of Common Stock are delivered in respect of such Early Settlement or the Fundamental Change Early Settlement Date, as the case may be, the Company shall pay all deferred Contract Adjustment Payments
(including Compounded Contract Adjustment Payments thereon) then due in the manner set forth in Section 5.09(a) (in the case of the end of an Extension Period), in the manner set forth in
Section 5.06(b) (in the case of an Early Settlement) or in the manner set forth in Section 5.04 (in the case of a Fundamental Change Early Settlement) to the extent such amounts are not deducted
from the amount otherwise payable by the Holder in the case of any Early Settlement or any Fundamental Change Early Settlement. In the event of an Early Settlement, the Company shall pay all deferred Contract Adjustment Payments (including
Compounded Contract Adjustment Payments thereon) then payable, if any, on the Purchase Contracts being settled early through the Contract Adjustment Payment Date immediately preceding the applicable Early Settlement Date. In the event of a
Fundamental Change Early Settlement, the Company shall pay all deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon) due on the Purchase Contracts being settled on the Fundamental Change Early Settlement
Date to, but excluding, such Fundamental Change Early Settlement Date. 

  
 79 

 Upon termination of any Extension Period and the payment of all deferred Contract Adjustment Payments
(including Compounded Contract Adjustment Payments thereon) and all accrued and unpaid Contract Adjustment Payments then due, the Company may commence a new Extension Period; provided that such Extension Period, together with all extensions
thereof, may not extend beyond the Purchase Contract Settlement Date (or any applicable Early Settlement Date or Fundamental Change Early Settlement Date). Except in the case of an Early Settlement or Fundamental Change Early Settlement, no Contract
Adjustment Payments shall be due and payable during an Extension Period except at the end thereof. 
 (b) The Company shall give written
notice to the Purchase Contract Agent (and the Purchase Contract Agent shall promptly thereafter give notice thereof to Holders of Purchase Contracts) of its election to extend any period for the payment of Contract Adjustment Payments, the expected
length of any such Extension Period and any extension of any Extension Period, at least five Business Days before the earlier of (i) the Record Date for the Contract Adjustment Payment Date on which Contract Adjustment Payments would have been
payable except for the election to begin or extend the Extension Period or (ii) the date the Purchase Contract Agent is required to give notice to any securities exchange or to Holders of Purchase Contracts of such Record Date or such Contract
Adjustment Payment Date. 
 (c) The Company shall give written notice to the Purchase Contract Agent (and the Purchase Contract Agent shall
promptly thereafter give notice thereof to Holders of Purchase Contracts) of the end of an Extension Period or its election to pay any portion of the deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon)
on a Contract Adjustment Payment Date prior to the end of an Extension Period, at least five Business Days before the earlier of (i) the Record Date for the Contract Adjustment Payment Date on which such Extension Period shall end or such
payment of deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon) shall be made or (ii) the date the Purchase Contract Agent is required to give notice to any securities exchange or to Holders of
Purchase Contracts of such Record Date or such Contract Adjustment Payment Date. 

  
 80 

 (d) In the event the Company exercises its option to defer the payment of Contract
Adjustment Payments, then, until all deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon) have been paid, the Company shall not (1) declare or pay any dividends on, or make any distributions on, or
redeem, purchase or acquire, or make a liquidation payment with respect to, any shares of the Company’s capital stock (including the Mandatory Convertible Preferred Stock), (2) make any payment of principal of, or interest or premium, if any,
on, or repay, repurchase or redeem any of the Company’s debt securities that rank on parity with, or junior to, the Contract Adjustment Payments, or (3) make any guarantee payments under any guarantee by the Company of securities of any of
its Subsidiaries if the Company’s guarantee ranks on parity with, or junior to, the Contract Adjustment Payments; provided that the foregoing does not apply to: 

(i) purchases, redemptions or other acquisitions of the Company’s capital stock in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors, agents or consultants or a stock purchase or dividend reinvestment plan, or the satisfaction of the Company’s obligations pursuant to
any contract or security outstanding on the date that the Contract Adjustment Payment is deferred requiring the Company to purchase, redeem or acquire its capital stock; 

(ii) any payment, repayment, redemption, purchase, acquisition or declaration of dividends described in clause (i) as a
result of a reclassification of the Company’s capital stock, or the exchange or conversion of all or a portion of one class or series of the Company’s capital stock, for another class or series of the Company’s capital stock; 

(iii) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange
provisions of the Company’s capital stock or the security being converted or exchanged; 
 (iv) dividends or
distributions paid or made in the Company’s capital stock (or rights to acquire the Company’s capital stock), or repurchases, redemptions or acquisitions of capital stock in connection with the issuance or exchange of capital stock (or of
securities convertible into or exchangeable for shares of the Company’s capital stock); 
 (v) redemptions, exchanges or
repurchases of, or with respect to, any rights outstanding under a shareholder rights plan outstanding on the date that the Contract Adjustment Payment is deferred or the declaration or payment thereunder of a dividend or distribution of or with
respect to rights in the future; 
 (vi) payments on any trust preferred securities, subordinated debentures, junior
subordinated debentures or junior subordinated notes, or any guarantees of any of the foregoing, in each case, that rank equal in right of payment with the Contract Adjustment Payments, so long as the amount of payments made on account of such
securities or guarantees and the Purchase Contracts is paid on all such securities and guarantees and the Purchase Contracts then outstanding on a pro rata basis in proportion to the full payment to which each series of such securities,
guarantees or Purchase Contracts is then entitled if paid in full; provided that, for the avoidance of doubt, the Company shall not make Contract Adjustment Payments in part; or 

  
 81 

 (vii) any payment of deferred interest or principal on, or repayment,
redemption or repurchase of, parity or junior securities that, if not made, would cause the Company to breach the terms of the instrument governing such parity or junior securities. 

Section 5.11. Anti-dilution Adjustments. The Maximum Settlement Rate shall be subject to the following adjustments: 

(a) If the Company issues Common Stock as a dividend or distribution on the Common Stock to all or substantially all holders of the Common
Stock, or the Company effects a share split or share combination, the Maximum Settlement Rate shall be adjusted based on the following formula: 
  

 
 where, 
 SR0 = the Maximum Settlement Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution or immediately prior to the open of business on the
effective date for such share split or share combination, as the case may be; 
 SR1 = the
Maximum Settlement Rate in effect immediately after the close of business on such Record Date or immediately after the open of business on such effective date, as the case may be; 

OS = the number of shares of Common Stock outstanding immediately prior to the close of business on such Record Date or immediately prior to the open
of business on such effective date, as the case may be, in each case, prior to giving effect to such event; and 
 OS1 = the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such event. 

Any adjustment made pursuant to this clause ((a)) shall become effective as of the close of business on the Record Date for such dividend or other
distribution or as of the open of business on the effective date for such share split or share combination becomes effective, as applicable. If any dividend or distribution in this clause ((a)) is declared but not so paid or made, the new
Maximum Settlement Rate shall be readjusted, on the date that the Board of Directors determines not to pay or make such dividend or distribution, to the Maximum Settlement Rate that would then be in effect if such dividend or distribution had not
been declared. 
 (b) If the Company distributes to all or substantially all holders of Common Stock any rights, options or warrants
entitling them for a period of not more than 45 calendar days after the date of distribution thereof to subscribe for or purchase Common Stock, in any case at an exercise price per share of Common Stock less than the average of the Closing Prices of
the Common Stock for the 10 consecutive Trading Days ending on, and including, the Trading Day immediately preceding the date of the announcement of such distribution, the Maximum Settlement Rate shall be increased based on the following formula:

  
 82 

 

 
 where, 
 SR0 = the Maximum Settlement Rate in effect immediately prior to the close of business on the Record Date for such distribution; 

SR1 = the Maximum Settlement Rate in effect immediately after the close of business on such
Record Date; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to
the close of business on the Record Date for such distribution; 
 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 quotient of (A) the aggregate price payable to exercise such rights, options
or warrants divided by (B) the average of the Closing Prices of the Common Stock for the 10 consecutive Trading Days ending on, and including, the Trading Day immediately preceding the date of the announcement of the distribution of such
rights, options or warrants. 
 If any right, option or warrant described in this clause ((b)) is not exercised or converted prior to the expiration of
the exercisability or convertibility thereof (and as a result no additional shares of Common Stock are delivered or issued pursuant to such rights, options or warrants), the new Maximum Settlement Rate shall be readjusted, as of the date of such
expiration, to the Maximum Settlement Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery or issuance of only the number of shares of Common Stock
actually delivered. 
 For purposes of this clause ((b)), in determining whether any rights, options or warrants entitle the holders thereof to
subscribe for or purchase shares of Common Stock at a price per share of Common Stock less than the average of the Closing Prices of the Common Stock for the 10 consecutive Trading Days ending on, and including, the Trading Day immediately preceding
the date of the announcement of the distribution of such rights, options or warrants, and in determining the aggregate price payable to exercise such rights, options or warrants, 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, with the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors. 

Any increase to the Maximum Settlement Rate made under this clause ((b)) shall be made successively whenever any such rights, options or warrants are
issued and shall become effective immediately after the close of business on the Record Date for such distribution. 

  
 83 

 (c) (1) If the Company distributes shares of capital stock, evidences of indebtedness
or other assets or property of the Company or rights, options or warrants to acquire the Company’s capital stock or other securities to all or substantially all holders of Common Stock (excluding (i) any dividend, distribution or issuance
as to which an adjustment was effected pursuant to clause ((a)) or ((b)) above, (ii) any dividend or distribution paid exclusively in Cash, and (iii) any Spin-Off to which the
provisions in clause (c)(2) below apply), the Maximum Settlement Rate shall be increased based on the following formula: 
  

 
 where, 
 SR0 = the Maximum Settlement Rate in effect immediately prior to the close of business on the Record Date for such distribution; 

SR1 = the Maximum Settlement Rate in effect immediately after the close of business on such Record
Date; 
 SP0 = the Closing Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and 
 FMV = the fair market value (as determined in good faith by the
Board of Directors), on the Record Date for such dividend or distribution, of the shares of capital stock, evidences of indebtedness, assets or property so distributed, expressed as an amount per share of Common Stock. 

An adjustment to the Maximum Settlement Rate made pursuant to this Section 5.11(c)(1) shall become effective as of the close of
business on the Record Date for such distribution. 
 Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Purchase Contract shall receive, for each Purchase Contract, at the same time and upon the same terms as
holders of shares of Common Stock, the amount of such distributed shares of capital stock, evidences of indebtedness or other assets or property that such Holder would have received if such Holder owned a number of shares of Common Stock equal to
the Maximum Settlement Rate on the Record Date for such dividend or distribution. 
 (2) However, if the Company distributes to all or
substantially all holders of Common Stock, capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit, in each case, that is, or when issued, will be, listed or admitted for trading on a
U.S. national securities exchange (a “Spin-Off”), then the Maximum Settlement Rate shall instead be increased based on the following formula: 

 
 

 

  
 84 

 where, 

SR0 = the Maximum Settlement Rate in effect immediately prior to the end of the Valuation
Period; 
 SR1 = the Maximum Settlement Rate in effect immediately after the end of the
Valuation Period; 
 FMV0 = the
average of the closing prices of the capital stock or similar equity interests distributed to holders of Common Stock applicable to one share of Common Stock over each of the 10 consecutive Trading Days commencing on, and including, the Ex-Dividend Date for such dividend or distribution (the “Valuation Period”); and 
 MP0 = the average of the Closing Prices of the Common Stock over the Valuation Period. 
 The adjustment to
the Maximum Settlement Rate under this clause (c)(2) shall occur at the close of business on the last Trading Day of the Valuation Period; provided that if a Holder elects to early settle the Purchase Contracts
pursuant to Section 5.04 or Section 5.06, or the Purchase Contract Settlement Date occurs, in either case, during the Valuation Period, references with respect to 10 Trading Days shall be
deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the date on which such Holder elected its early
settlement right pursuant to Section 5.04 or Section 5.06, or the Business Day immediately preceding the Purchase Contract Settlement Date, as the case may be, in determining the applicable
Maximum Settlement Rate. 
 If any dividend or distribution described in this clause (c) is declared but not so paid or made, the
new Maximum Settlement Rate shall be readjusted, as of the date the Board of Directors determines not to pay or make such dividend or distribution, to the Maximum Settlement Rate that would then be in effect if such dividend or distribution had not
been declared. 
 (d) If any Cash dividend or distribution is made to all or substantially all holders of Common Stock other than a regular,
quarterly Cash dividend that does not exceed $0.22 per share (the “Reference Dividend”), the Maximum Settlement Rate shall be increased based on the following formula: 

 
 

 
 where, 
 SR0 = the Maximum Settlement Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution; 

SR1 = the Maximum Settlement Rate in effect immediately after the close of business on such Record
Date; 
 SP0 = the Closing Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; 

  
 85 

 T = the Reference Dividend; provided that if the dividend or distribution is not a regular quarterly
Cash dividend, the Reference Dividend shall be deemed to be zero; and 
 C = the amount in Cash per share the Company distributes to all or substantially
all holders of Common Stock. 
 Any increase to the Maximum Settlement Rate made pursuant to this Section 5.11(d) shall become
effective as of the close of business on the Record Date for such dividend or distribution. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than
“SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Purchase Contract shall receive, for each Purchase Contract, at the same time and upon the same terms as
holders of shares of Common Stock, the amount of distributed Cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Settlement Rate on the Record Date for such cash dividend or
distribution. 
 The Reference Dividend shall be subject to an inversely proportional adjustment whenever the Maximum Settlement Rate is adjusted, other
than pursuant to this clause ((d)). For the avoidance of doubt, the Reference Dividend shall be zero in the case of a Cash dividend that is not a regular quarterly dividend. 

If any dividend or distribution described in this clause ((d)) is declared but not so paid or made, the new Maximum Settlement Rate
shall be readjusted, as of the date the Board of Directors determines not to pay or make such dividend or distribution, to the Maximum Settlement Rate that would then be in effect if such dividend or distribution had not been declared. 

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock to the extent
that the Cash and value of any other consideration included in the payment per share of Common Stock validly tendered or exchanged exceeds the Closing Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender or exchange offer, the Maximum Settlement Rate shall be increased based on the following formula: 
  

 
 where, 
 SR0 = the Maximum Settlement Rate in effect immediately prior to the close of business on the Trading Day immediately following the date on which such tender or exchange offer expires; 

SR1 = the Maximum Settlement Rate in effect immediately after the close of business on
the Trading Day immediately following the date on which such tender or exchange offer expires; 
 FMV = the fair market value (as determined in good
faith by the Board of Directors, whose good faith determination shall be conclusive), at the close of business on the Trading Day immediately following the date on which such tender or exchange offer expires, of the aggregate value of all Cash and
any other consideration paid or payable for shares validly tendered or exchanged and not withdrawn as of the expiration date; 

  
 86 

 OS0 = the number of shares of Common Stock
outstanding immediately prior to the last time tenders or exchanges may be made pursuant to such tender or exchange offer (prior to giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer); 

OS1 = the number of shares of Common Stock outstanding immediately after the last time tenders
or exchanges may be made pursuant to such tender or exchange offer (after giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer); and 

SP1 = the Closing Price of the Common Stock on the Trading Day next succeeding the date such
tender or exchange offer expires. 
 The adjustment to the Maximum Settlement Rate under this Section 5.11(e) shall occur at the
close of business on the Trading Day immediately following the date on which such tender or exchange offer expires. 
 (f) To the extent that
the Company has a shareholders rights plan involving the issuance of share purchase rights or other similar rights to all or substantially all holders of the Common Stock in effect upon settlement of a Purchase Contract, the Holder thereof will
receive, in addition to the Common Stock issuable upon settlement of such Purchase Contract, the related rights for the Common Stock under the shareholders rights plan, unless, prior to any settlement of such Purchase Contract, the rights have
separated from the Common Stock, in which case the Maximum Settlement Rate shall be adjusted at the time of separation as if the Company made a distribution to all holders of Common Stock as described in clause (c)(1)
above, subject to readjustment in the event of the expiration, termination or redemption of the rights under the shareholder rights plan. 

(g) The Company may increase the Maximum Settlement Rate if the Board of Directors deems it advisable to avoid or diminish any income tax to
holders of the Common Stock resulting from any dividend or distribution of shares (or rights to acquire shares) or from any event treated as a dividend or distribution for income tax purposes or for any other reasons. 

(h) Adjustments to the Maximum Settlement Rate shall be calculated by the Company to the nearest ten thousandth of a share. No adjustment to
the Maximum Settlement Rate shall be required unless the adjustment would require an increase or decrease of at least one percent in the Maximum Settlement Rate. If any adjustment is not required to be made because it would not change the Maximum
Settlement Rate by at least one percent, then the adjustment shall be carried forward and taken into account in any subsequent adjustment. All adjustments shall be made not later than the Purchase Contract Settlement Date, any Early Settlement Date,
any Fundamental Change Early Settlement Date and the time at which the Company is required to determine the relevant Settlement Rate or amount of Make-Whole Shares (if applicable) in connection with any settlement with respect to the Purchase
Contracts. 
 (i) No adjustment to the Maximum Settlement Rate shall be made if Holders participate, as a result of holding the Purchase
Contracts and without having to settle the Purchase Contracts that form part of the Units, in the transaction that would otherwise give rise to an adjustment as if they held, per Purchase Contract, a number of shares of Common Stock equal to the
Maximum Settlement Rate, at the same time and upon the same terms as the holders of Common Stock participate in the transaction. 

  
 87 

 (j) Except as described in Section 5.11(a), ((b)),
(c), ((d)) and ((e)) above, the Maximum Settlement 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 options, restricted stock or other awards in connection with any employment contract,
executive compensation plan, benefit plan or other similar arrangement with or for the benefit of any one or more employees, officers, directors, consultants or independent contractors or the exercise of such options or other awards; 

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security outstanding as of the date the Units were first issued; 
 (iv) for a change in the par value or no par
value of the Common Stock; or 
 (v) for accrued and unpaid Contract Adjustment Payments. 

(k) If an adjustment is made to the Maximum Settlement Rate, an adjustment also shall be made to the Reference Price on an inversely
proportional basis solely to determine which of the clauses of the definition of Settlement Rate shall be applicable to determine the Settlement Rate with respect to the Purchase Contract Settlement Date, any Early Settlement Date or any Fundamental
Change Early Settlement Date. 
 (l) If any adjustment to the Maximum Settlement Rate becomes effective, or any effective date, expiration
date, Ex-Dividend Date or Record Date for any stock split or reverse stock split, tender or exchange offer, issuance, dividend or distribution (relating to a required Maximum Settlement Rate adjustment)
occurs, during the period beginning on, and including, (i) the open of business on a first Trading Day of the Market Value Averaging Period or (ii) in the case of an Early Settlement or Fundamental Change Early Settlement, the relevant
Early Settlement Date or the Fundamental Change Early Settlement Date and, in each case, ending on, and including, the date on which the Company delivers shares of Common Stock under the related Purchase Contract, the Company shall make appropriate
adjustments to the Maximum Settlement Rate, the Reference Price and/or the number of shares of Common Stock deliverable upon settlement with respect to the Purchase Contract, in each case, consistent with the methodology used to determine the
anti-dilution adjustments set forth in this Section 5.11. If any adjustment to the Maximum Settlement Rate becomes effective, or any effective date, expiration date, Ex-Dividend Date
or Record Date for any stock split or reverse stock split, 

  
 88 

 
tender or exchange offer, issuance, dividend or distribution (in each case, relating to a required Maximum Settlement Rate adjustment) occurs, during the period used to determine the Applicable
Market Value, Stock Price, the Five-Day Average Period or any other averaging or similar period hereunder, the Company shall make appropriate adjustments to the applicable prices, consistent with the
methodology used to determine the anti-dilution adjustments set forth in this Section 5.11. 
 (m) (i)
Whenever the Maximum Settlement Rate is adjusted as herein provided, the Company shall, as promptly as practicable following the occurrence of an event that requires an adjustment pursuant to this Section 5.11 (or if the
Company is not aware of such occurrence, as soon as practicable after becoming so aware): 
 (A) compute the adjusted Maximum
Settlement Rate in accordance with this Section 5.11 and prepare and transmit to the Purchase Contract Agent an Officer’s Certificate setting forth the adjusted Maximum Settlement Rate, the method of calculation
thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and 
 (B)
provide a written notice to the Holders of the Units and the Purchase Contract Agent of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Maximum Settlement Rate was determined
and setting forth the adjusted Maximum Settlement Rate. 
 (ii) The Purchase Contract Agent shall not at any time be under
any duty or responsibility to any Holder to determine whether any facts exist which may require any adjustment of the Maximum Settlement Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect
to the method employed in making the same. The Purchase Contract Agent shall be fully authorized and protected in relying on any Officer’s Certificate delivered pursuant to Section 5.11(m)(i) and any adjustment
contained therein and the Purchase Contract Agent shall not be deemed to have knowledge of any adjustment unless and until it has received such Officer’s Certificate. The Purchase Contract Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at the time be issued or delivered with respect to any Purchase Contract; and the Purchase Contract Agent makes no representation
with respect thereto. The Purchase Contract Agent shall not be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock pursuant to a Purchase Contract or to comply with any of the duties, responsibilities
or covenants of the Company contained in this Article 5. 
 Section 5.12. Reorganization Events.
The following events are defined as “Reorganization Events”: 
 (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; 

  
 89 

 (iii) any sale, lease or other transfer to another Person of the
consolidated assets of the Company and its Subsidiaries substantially as an entirety; or 
 (iv) any statutory exchange of
the Common Stock; 
 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) (“Exchange Property”). 
 Following the effective date of a Reorganization Event, the
Settlement Rate shall be determined by reference to the value of an Exchange Property Unit, and the Company shall deliver, upon settlement of any Purchase Contract, a number of Exchange Property Units equal to the number of shares of Common Stock
that it would otherwise be required to deliver. In the event holders of Common Stock (other than any Constituent Person or Affiliate thereof) have the opportunity to elect the form of consideration to be received in any Reorganization Event, the
Exchange Property Unit that Holders of the Units are entitled to receive will be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock. 

In the event of such a Reorganization Event, the Person formed by such consolidation or surviving such merger or, if other than the Company, the Person which
acquires the Company’s assets and those of the Company’s Subsidiaries substantially as an entirety, shall execute and deliver to the Purchase Contract Agent an agreement providing that the holder of each Unit that remains outstanding after
the Reorganization Event (if any) will have the rights described in the preceding paragraph and expressly assuming all of the Company’s obligations under the Purchase Contracts, this Agreement, the Mandatory Convertible Preferred Stock and the
Remarketing Agreement. Such supplemental agreement shall provide for adjustments to the amount of any securities constituting all or a portion of an Exchange Property Unit and/or adjustments to the Maximum Settlement Rate, which, for events
subsequent to the effective date of such Reorganization Event, will be as nearly equivalent as may be practicable, as determined by the Company in its sole commercially reasonable discretion, to the adjustments provided for under
Section 5.11 (it being understood that any such adjustment may be zero and that no such adjustments shall be required with respect to any portion of the Exchange Property that consists of cash). 

In connection with any Reorganization Event, the Company shall also adjust the Reference Dividend based on the number of shares of common stock comprising an
Exchange Property Unit and (if applicable) the value of any non-stock consideration comprising an Exchange Property Unit. If an Exchange Property Unit is composed solely of
non-stock consideration, the Reference Dividend shall be zero. 
 The provisions described in this
Section 5.12 shall similarly apply to successive Reorganization Events.

 ARTICLE 6 

RIGHTS AND REMEDIES OF HOLDERS 

Section 6.01. Unconditional Right of Holders to Receive Contract Adjustment Payments and to Purchase Shares of Common Stock.
Each Holder of a Unit shall have the right, which is absolute and unconditional, (a) subject to Article 5, to receive each Contract Adjustment Payment and deferred Contract Adjustment Payment with respect to
the Purchase Contract comprising part of such Unit on the respective Contract Adjustment Payment Date for such Unit pursuant to the terms hereof and (b) except upon and following a Termination Event, to purchase shares of Common Stock pursuant
to such Purchase Contract and, in each such case, to institute suit for the enforcement of any such right to receive Contract Adjustment Payments and the right to purchase shares of Common Stock, and such rights shall not be impaired without the
consent of such Holder. 
 Section 6.02. Restoration of Rights and Remedies. If any Holder has instituted any proceeding
to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding,
the Company, the Purchase Contract Agent, the Collateral Agent, the Custodial Agent, the Securities Intermediary and such Holder shall be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies
of such Holder shall continue as though no such proceeding had been instituted. 
 Section 6.03. Rights and Remedies
Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates in the last paragraph of Section 3.09, no right or remedy herein conferred
upon or reserved to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 6.04. Delay or Omission Not Waiver. No delay or omission of any Holder to exercise any right upon a default or
remedy upon a default shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article 6 or by law to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by such Holders. 
 Section 6.05. Undertaking for Costs. All parties to this Agreement agree,
and each Holder of a Unit, by its acceptance of such Unit shall be deemed to have agreed, that any court of competent jurisdiction may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any
suit against the Purchase Contract Agent for any action taken, suffered or omitted by it as Purchase Contract Agent, 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 costs against any party litigant in such suit, having due regard to the merits and good faith of the claims or 

  
 91 

 
defenses made by such party litigant; provided that the provisions of this Section 6.05 shall not apply to any suit instituted by the Purchase Contract Agent, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the Outstanding Units, or to any suit instituted by any Holder for the enforcement of the obligation to pay Contract Adjustment Payments on or after
the Contract Adjustment Payment Date therefor in respect of any Unit held by such Holder, or for enforcement of the right to purchase shares of Common Stock under the Purchase Contracts constituting part of any Unit held by such Holder. 

Section 6.06. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of
this Agreement; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the
Purchase Contract Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted. 

ARTICLE 7 
 THE
PURCHASE CONTRACT AGENT 
 Section 7.01. Certain Duties and Responsibilities. 

(a) The Purchase Contract Agent hereby appointed by the Company: 

(i) undertakes to perform, with respect to the Units, such duties and only such duties as are specifically set forth in this
Agreement and the Remarketing Agreement to be performed by the Purchase Contract Agent and no implied covenants or obligations shall be read into this Agreement or the Remarketing Agreement against the Purchase Contract Agent; and 

(ii) may conclusively rely, in the absence of bad faith on its part, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the Purchase Contract Agent and conforming to the requirements of this Agreement or the Remarketing Agreement, as applicable, but in the case of any certificates or opinions
which by any provision hereof are specifically required to be furnished to the Purchase Contract Agent, the Purchase Contract Agent shall be under a duty to examine the same to determine whether or not they conform to the requirements of this
Agreement or the Remarketing Agreement, as applicable (but need not confirm or investigate the accuracy of the mathematical calculations or other facts, statements, opinions, conclusions or matters stated therein). 

(b) No provision of this Agreement or the Remarketing Agreement shall be construed to relieve the Purchase Contract Agent from liability for
its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that: 

  
 92 

 (i) this Section 7.01(b) shall not be construed to
limit the effect of Section 7.01(a) or Section 7.01(c); 
 (ii) the
Purchase Contract Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be conclusively determined by a court of competent jurisdiction that the Purchase Contract Agent was grossly negligent
in ascertaining the pertinent facts; and 
 (iii) the Purchase Contract Agent shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority of the aggregate stated amount of the Outstanding Certificates, relating to the time, method and place of conducting any proceeding for
any right or remedy available to the Purchase Contract Agent, or exercising any power conferred upon the Purchase Contract Agent, under this Agreement with respect to the Units. 

(c) No provision of this Agreement, the Remarketing Agreement, the Certificate of Designations or any Certificate shall require the Purchase
Contract Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity and/or security against such risk or liability is not reasonably assured to it. 
 (d) Whether
or not therein expressly so provided, every provision of this Agreement, the Remarketing Agreement, the Certificate of Designations and any Certificate relating to the conduct or affecting the liability of or affording protection to the Purchase
Contract Agent shall be subject to the provisions of this Section 7.01. 
 (e) The Purchase Contract Agent is
authorized to execute and deliver the Remarketing Agreement in its capacity as Purchase Contract Agent. The rights, privileges, protections, immunities and benefits afforded to the Purchase Contract Agent and each Indemnitee under this Agreement,
including, without limitation, its and their rights to be compensated, reimbursed and indemnified, shall also extend to and cover the Purchase Contract Agent and each Indemnitee with respect to the role of the Purchase Contract Agent as Purchase
Contract Agent under, including action taken, omitted to be taken or suffered by the Purchase Contract Agent pursuant to the Remarketing Agreement, the Certificate of Designations, any Certificate or any notice or instruction entered into by the
Purchase Contract Agent under the terms of this Agreement. 
 (f) The Purchase Contract Agent shall be under no duty to afford the Collateral
any greater degree of care than it gives to its own similar property. In acting hereunder, the Purchase Contract Agent shall act solely as the attorney-in-fact and the
agent for the Holders hereunder (and not as a fiduciary). 
 (g) None of the Purchase Contract Agent, the Collateral Agent, the Custodial
Agent nor the Securities Intermediary shall be responsible for any calculations under this Agreement or with respect to the Units. 

  
 93 

 (h) The Purchase Contract Agent may hold Common Stock but, for the avoidance of doubt, will
not be required to issue shares of Common Stock. 
 (i) The Purchase Contract Agent shall not at any time be under any duty or responsibility
to any Holder to determine the Settlement Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Settlement 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 in this Agreement or in any supplemental agreement hereunder provided to be employed, in making the same. The Purchase Contract Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the settlement of any Purchase Contract; and the Purchase Contract Agent make no
representations with respect thereto. The Purchase Contract Agent shall not 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 Purchase Contract for the purpose of settlement or to comply with any of the duties, responsibilities or covenants of the Company contained in this Agreement. Without limiting the generality of the foregoing, the Purchase Contract
Agent shall not be under any responsibility to (a) determine whether a supplemental agreement needs to be entered into or (b) determine the correctness of any provisions contained in any supplemental agreement, in each case, entered into
pursuant to Section 5.12 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the settlement of their Purchase Contract pursuant to Article 5 or to any adjustment to be
made with respect thereto, but may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officer’s Certificate (which the
Company shall be obligated to file with the Purchase Contract Agent prior to the execution of any such supplemental agreement) with respect thereto. 

Section 7.02. Notice of Default. Within 90 calendar days after the occurrence of any default by the Company hereunder of
which a Responsible Officer of the Purchase Contract Agent has received written notice thereof and such notice references the Company, the Units and this Agreement, the Purchase Contract Agent shall transmit by mail to the Holders, as their names
and addresses appear in the Security Register, notice of such default hereunder, unless such default shall have been cured or waived; provided that, except for a default in any payment obligation hereunder, the Purchase Contract Agent shall
be protected in withholding such notice if and for so long as a Responsible Officer of the Purchase Contract Agent in good faith determines that the withholding of such notice is in the interests of Holders of the Units. 

Section 7.03. Certain Rights of Purchase Contract Agent. 

Subject to the provisions of Section 7.01: 

(a) the Purchase Contract Agent may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by

request, instruction or order signed in the name of such Beneficial Owner by an authorized representative of such Beneficial Owner and certifying to the Purchase Contract Agent that such Person is a Beneficial Owner under the terms of this
Agreement; the Purchase Contract Agent shall have the right to require that any directions, instructions or notices provided to it be signed by an authorized representative of such Beneficial Owner, be provided on corporate letterhead or contain a
medallion signature guarantee, or contain such other evidence as may be reasonably requested by it, to establish the identity and/or signatures thereon; in acting hereunder, in the absence of gross negligence or willful misconduct by the Purchase
Contract Agent, the Purchase Contract Agent shall be fully authorized and protected in relying upon any such request, instruction, direction and certification received by a Beneficial Owner hereunder; 

(d) whenever in the administration of this Agreement, the Remarketing Agreement, the Certificate of Designation or the Certificates, the
Purchase Contract Agent shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting to take any action hereunder or thereunder, the Purchase Contract Agent (unless other evidence be herein specifically
prescribed in this Agreement) may, in the absence of bad faith, conclusively rely upon an Officer’s Certificate or an Opinion of Counsel; 

(e) the Purchase Contract Agent may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be
full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, or inquire as to the performance by the Company of any of its covenants in this
Agreement, but the Purchase Contract Agent may make reasonable further inquiry or investigation into such facts or matters related to the execution, delivery and performance of the Purchase Contracts as it may see fit, and shall incur no liability
or additional liability of any kind by reason of such inquiry or investigation; 
 (g) the Purchase Contract Agent may execute any of the
powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys, custodians or nominees or an Affiliate of the Purchase Contract Agent and the Purchase Contract Agent shall not be responsible for any misconduct or
negligence on the part of any agent, attorney, custodian or nominee or an Affiliate appointed with due care by it hereunder; 
 (h) the
Purchase Contract Agent shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement at the request or direction of any of the Holders pursuant to this Agreement, unless such Holders shall have offered to the
Purchase Contract Agent security and/or indemnity satisfactory to the Purchase Contract Agent against the costs, expenses, claims and liabilities which might be incurred by it in compliance with such request or direction; 

  
 95 

 (i) the Purchase Contract Agent shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and believed by it to be authorized or within the rights or powers conferred upon it by this Agreement; 

(j) the rights, privileges, protections, immunities and benefits given to the Purchase Contract Agent, including, without limitation, its right
to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Purchase Contract Agent in each of its capacities hereunder, and to each officer, director, employee of the Purchase Contract Agent and each agent,
custodian and other Person employed, in any capacity whatsoever, by the Purchase Contract Agent to act hereunder and shall survive the resignation or removal of the Purchase Contract Agent and the termination for any reason of this Agreement and the
termination, satisfaction and discharge of the Units and the Purchase Contracts; 
 (k) the Purchase Contract Agent shall not be deemed to
have notice or be charged with knowledge of any Fundamental Change, Termination Event or any default hereunder unless a Responsible Officer of the Purchase Contract Agent has received written notice from the Company or any Holder of such Fundamental
Change, Termination Event or default at the Corporate Trust Office of the Purchase Contract Agent, and such notice references the Company, the Units and this Agreement and, in the case of a default, identifies such default; 

(l) the Purchase Contract Agent may request that the Company deliver a certificate setting forth the names of individuals and/or titles of
officers authorized at such time to take specified actions pursuant to this Agreement along with specimen signatures, which Officer’s Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person
specified as so authorized in any such certificate previously delivered and not superseded; 
 (m) anything in this Agreement
notwithstanding, in no event shall the Purchase Contract Agent be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Purchase Contract Agent has
been advised as to the likelihood of such loss or damage and regardless of the form of action; 
 (n) the Purchase Contract Agent shall not
be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its reasonable control, including strikes, work stoppages, accidents, acts of war or
terrorism, civil or military disturbances, pandemics, epidemics, recognized public emergencies, quarantine restrictions, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer
(software and hardware) services, hacking, cyber-attacks, or other use or infiltration of the Purchase Contract Agent’s technological infrastructure exceeding authorized access, or the unavailability of the Federal Reserve Bank wire or
facsimile or other wire or communication facility, it being understood that the Purchase Contract Agent shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable
under the circumstances; 

  
 96 

 (o) the Purchase Contract Agent shall not be required to give any bond or surety in respect
of the performance of its powers or duties hereunder; 
 (p) the duties of the Purchase Contract Agent hereunder and under the Remarketing
Agreement and under any other document or instrument referred to or provided for herein or in connection herewith are solely ministerial and administrative in nature; 

(q) the Purchase Contract Agent shall not be required to initiate or conduct any litigation or collection proceedings hereunder and shall have
no responsibilities with respect to any default hereunder, in each case, except as expressly set forth herein; 
 (r) the permissive right of
the Purchase Contract Agent to take or refrain from taking action hereunder shall not be construed as a duty; and 
 (s) as to any
discretionary action or matters not expressly provided for by this Agreement, the Purchase Contract Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder in accordance with instructions given by the Company
or the Holders, as the case may be; provided, however, it is understood that in all cases the Purchase Contract Agent shall be fully justified in failing or refusing to take any such action under this Agreement if it shall not have
received such direction from the Company or the Holders (acting in accordance with this Agreement); this provision is intended solely for the benefit of the Purchase Contract Agent and its successors and permitted assigns and is not intended to and
will not entitle the other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto. 

Section 7.04. Not Responsible for Recitals or Issuance of Units. The recitals contained herein, in the Remarketing
Agreement, and in the Certificates shall be taken as the statements of the Company, and the Purchase Contract Agent assumes no responsibility for their accuracy or validity. The Purchase Contract Agent makes no representations as to the validity or
sufficiency of either this Agreement or of the Units or the Pledge or the Collateral or the Remarketing Agreement or any other agreement, document or instrument referred to or provided for herein or in connection herewith and shall have no
responsibility for perfecting or maintaining the perfection of any security interest in the Collateral nor for making any calculations hereunder. The Purchase Contract Agent shall not be accountable for the use or application by the Company of the
proceeds in respect of the Purchase Contracts or for funds received and disbursed in accordance with this Agreement. The Purchase Contract Agent shall have no responsibility or liability with respect to any information, statement or recital in any
offering memorandum, prospectus, prospectus supplement or other disclosure material prepared or distributed with respect to the issuance of the Units. 

Section 7.05. May Hold Units. Any Security Registrar or any other agent of the Company, or the Purchase Contract Agent, in
their individual or any other capacity, may become the owner or pledgee of Units and may otherwise deal with the Company, the Collateral Agent or any other Person with the same rights it would have if it were not Security Registrar or such other
agent, or the Purchase Contract Agent. The Company may become the owner or pledgee of Units. 

  
 97 

 Section 7.06. Money Held in Custody. Money or other property held by the
Purchase Contract Agent in custody hereunder need not be segregated from the Purchase Contract Agent’s other funds except to the extent required by law or provided herein; provided, however, that when the Purchase Contract Agent holds
Cash as a component of the Treasury Portfolio, a Corporate Unit, a Treasury Unit or a Cash Settled Unit, such Cash shall be held in a segregated account hereunder. The Purchase Contract Agent shall be under no obligation to invest or pay interest on
any money received by it hereunder except as otherwise expressly provided hereunder or agreed in writing with the Company. If no standing instruction exists at the time any funds are received by the Purchase Contract Agent, the Securities
Intermediary or the Collateral Agent, such funds shall remain uninvested without liability for interest or other compensation thereon. The Collateral Agent shall not be responsible for or have a duty to ascertain or inquire into any representation
or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Collateral Agent’s liens thereon, or any certificate prepared by the Company in connection therewith, nor shall the
Collateral Agent be responsible or liable to the Company for any failure to monitor or maintain any portion of the Collateral. Beyond the exercise of reasonable care in the custody thereof and except as otherwise specifically set forth herein, the
Collateral Agent shall not have any duty as to any of the Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights
pertaining thereto and the Collateral Agent (A) shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee
selected by a Collateral Agent in good faith and with reasonable care, and (B) shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment
substantially equal to that which such Collateral Agent accords its own property. 
 Section 7.07. Compensation and
Reimbursement. 
 The Company agrees: 
 (a)
to pay to the Purchase Contract Agent compensation for all services rendered by it hereunder and under the Remarketing Agreement as the Company and the Purchase Contract Agent shall from time to time agree in writing; 

(b) to reimburse the Purchase Contract Agent upon its request for all reasonable expenses, disbursements and advances incurred or made by the
Purchase Contract Agent in accordance with any provision of this Agreement and the Remarketing Agreement (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or
advance as may be caused by its gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final, non-appealable decision); 

  
 98 

 (c) to indemnify the Purchase Contract Agent and any predecessor Purchase Contract Agent
(collectively, with the Purchase Contract Agent and its affiliates, officers, directors, employees, representatives and agents, the “Indemnitees”) for, and to hold each Indemnitee harmless against, any liabilities, obligations,
losses, damages, penalties, claims, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including reasonable fees and expenses of outside counsel) (including reasonable fees and expenses of counsel)
including taxes (other than taxes based upon, measured by or determined by the income of the Purchase Contract Agent) incurred without gross negligence, bad faith or willful misconduct on its part (as determined by a final, non-appealable judgment of a court of competent jurisdiction), arising out of or in connection with this Agreement, including the acceptance, performance or administration of its duties hereunder or under the
Remarketing Agreement, and the Indemnitees’ reasonable costs and expenses (including reasonable fees and expenses of counsel) of enforcing this Agreement and the Remarketing Agreement and defending themselves against any claim (whether asserted
by the Company, a Holder or any other Person) or liability in connection with the exercise or performance of any of the Purchase Contract Agent’s powers or duties hereunder or thereunder; provided that the Purchase Contract Agent shall
promptly notify the Company of any third-party claim of which a Responsible Officer has received written notice and which may give rise to the indemnity hereunder and give the Company the opportunity to control the defense of such claim with counsel
reasonably satisfactory to the applicable Indemnitee. Each Indemnitee may have separate counsel and the Company shall pay the fees and expenses of such counsel. Failure by the Purchase Contract Agent to so notify the Company shall not relieve the
Company of its obligations hereunder. Any settlement which affects the Purchase Contract Agent may not be entered into without the written consent of the Purchase Contract Agent, unless the Purchase Contract Agent is given a full and unconditional
release from liability with respect to the claims covered thereby and such settlement does not include a statement or admission of fault, culpability or failure to act by or on behalf of the Purchase Contract Agent; and 

(d) to pay or reimburse the Purchase Contract Agent for transfer, stamp, documentary or other similar taxes, assessments or charges levied by
any governmental or revenue authority in respect of this Agreement or any other document referred to herein. 
 When the Purchase Contract Agent incurs
expenses or renders services in connection with an insolvency, receivership, conservatorship, reorganization, readjustment of debt, marshaling of assets and liabilities or similar proceedings or any liquidation or
winding-up of or relating to the Company as a whole, whether voluntary or involuntary, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are
intended to constitute expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law. “Purchase Contract Agent” for purposes of this Section shall include any predecessor Purchase Contract
Agent; provided, however, that the gross negligence or willful misconduct of any Purchase Contract Agent hereunder shall not affect the rights of any other Purchase Contract Agent hereunder. 

The provisions of this Section 7.07 shall survive the resignation or removal of the Purchase Contract Agent and the termination for
any reason of this Agreement, and the termination, satisfaction and discharge of the Units and the Purchase Contracts. 

  
 99 

 Section 7.08. Corporate Purchase Contract Agent Required; Eligibility.
There shall at all times be a Purchase Contract Agent hereunder which shall be a Person organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to

 100

the Purchase Contract Agent, or (ii) any Holder who has been a bona fide Holder of a Unit for at least six months may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the
removal of the Purchase Contract Agent and the appointment of a successor Purchase Contract Agent. 
 (e) If the Purchase Contract Agent
shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Purchase Contract Agent for any cause, the Company, by a Board Resolution, shall promptly appoint a successor Purchase Contract Agent and shall
comply with the applicable requirements of Section 7.10(a). If no successor Purchase Contract Agent shall have been so appointed by the Company and accepted appointment in the manner required by
Section 7.10(a), any Holder who has been a bona fide Holder of a Unit for at least six months, on behalf of itself and all others similarly situated, or the Purchase Contract Agent may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor Purchase Contract Agent. 
 (f) The Company shall give, or
shall direct such successor Purchase Contract Agent in writing to give, notice of each resignation and each removal of the Purchase Contract Agent and each appointment of a successor Purchase Contract Agent by mailing written notice of such event by
first-class mail, postage prepaid, to all Holders as their names and addresses appear in the applicable Security Register. Each notice shall include the name of the successor Purchase Contract Agent and the address of its Corporate Trust Office.

 Section 7.10. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor
Purchase Contract Agent, every such successor Purchase Contract Agent so appointed shall execute, acknowledge and deliver to the Company and to the retiring Purchase Contract Agent an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Purchase Contract Agent shall become effective and such successor Purchase Contract Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of
the retiring Purchase Contract Agent; but, on the request of the Company or the successor Purchase Contract Agent, such retiring Purchase Contract Agent shall, upon payment of amounts owed to it pursuant to Section 7.07 hereof, execute and
deliver an instrument transferring to such successor Purchase Contract Agent all the rights, powers and trusts of the retiring Purchase Contract Agent and duly assign, transfer and deliver to such successor Purchase Contract Agent all property and
money held by such retiring Purchase Contract Agent hereunder. 
 (b) Upon request of any such successor Purchase Contract Agent, the Company
shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Purchase Contract Agent all such rights, powers and agencies referred to in Section 7.10.

Agent shall be qualified and eligible under this Article 7. 

  
 101 

 Section 7.11. Merger, Conversion, Consolidation or Succession to Business.
Any Person into which the Purchase Contract Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Purchase Contract Agent shall be a party, or any
Person succeeding to all or substantially all the corporate trust business of the Purchase Contract Agent, shall be the successor of the Purchase Contract Agent hereunder, provided that such Person shall be otherwise qualified and eligible
under this Article 7, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Certificates shall have been authenticated and executed on behalf of the Holders,
but not delivered, by the Purchase Contract Agent then in office, any successor by merger, conversion or consolidation to such Purchase Contract Agent may adopt such authentication and execution and deliver the Certificates so authenticated and
executed with the same effect as if such successor Purchase Contract Agent had itself authenticated and executed such Units. 

Section 7.12. Preservation of Information; Communications to Holders. (a) The Purchase Contract Agent shall preserve,
in as current a form as is reasonably practicable, the names and addresses of Holders received by the Purchase Contract Agent in its capacity as Security Registrar. 

(b) If three or more Holders (herein referred to as “Applicants”) apply in writing to the Purchase Contract Agent, and furnish
to the Purchase Contract Agent reasonable proof that each such Applicant has owned a Unit for a period of at least six months preceding the date of such application, and such application states that the Applicants desire to communicate with other
Holders with respect to their rights under this Agreement or under the Units and is accompanied by a copy of the form of proxy or other communication which such Applicants propose to transmit, then the Purchase Contract Agent shall mail to all the
Holders copies of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Purchase Contract Agent of the materials to be mailed and of payment, or provision for the payment, of
the reasonable expenses of such mailing. 
 Section 7.13. No Obligations of Purchase Contract Agent. Except to the extent
otherwise expressly provided in this Agreement, the Purchase Contract Agent assumes no obligations and shall not be subject to any liability under this Agreement, the Remarketing Agreement or any Purchase Contract in respect of the obligations of
the Holder of any Unit thereunder. The Company agrees, and each Holder of a Certificate, by its acceptance thereof, shall be deemed to have agreed, that the Purchase Contract Agent’s execution of the Certificates on behalf of the Holders shall
be solely as agent and attorney-in-fact for the Holders, and that the Purchase Contract Agent shall have no obligation to perform such Purchase Contracts on behalf of
the Holders, except to the extent expressly provided in Article 5 hereof. 
 Section 7.14. Tax
Compliance. (a) The Purchase Contract Agent shall comply in accordance with the terms hereof with any reasonable written direction received from the Company with respect to the execution or certification of any required documentation
and the application of such requirements to particular payments or Holders or in other particular circumstances, and may for purposes of this Agreement conclusively rely on any such direction in accordance with the provisions of
Section 7.01(a) hereof.    The Company shall be responsible for preparing any correspondence in response to inquiries received by the Company or the Purchase Contract Agent from any Holder or the
Depositary with respect to any tax matters hereunder and shall directly communicate with such Holder or the Depositary with respect to any such tax matters. 

  
 102

compliance with such requirements, and shall make such records available, on written request, to the Company or its authorized representative within a reasonable period of time after receipt of such request.

to enable the Company to comply with applicable tax laws (inclusive of rules, regulations and interpretations promulgated by competent authorities) in effect from time to time related to this Agreement, the Units or the Purchase Contracts. The
Company agrees to provide the Purchase Contract Agent with timely and sufficient information, upon which the Purchase Contract Agent shall be entitled to conclusively rely, in order to enable the Purchase Contract Agent to so assist the Company.

 Section 7.15. Acknowledgement of Appointment. The Company hereby acknowledges the appointment of U.S. Bank National
Association (“U.S. Bank”) to act as Purchase Contract Agent on behalf of the Holders hereunder and under the Remarketing Agreement or the Certificates, as applicable, and as their attorney-in-fact hereunder and under the Remarketing Agreement and the Certificates, as applicable. The Company accepts the authorizations, appointments, acknowledgments and other actions taken by the
Purchase Contract Agent in accordance with this Agreement, the Remarketing Agreement and the Certificates.

ARTICLE 9 

CONSOLIDATION, MERGER, SALE, CONVEYANCE, TRANSFER OR DISPOSITION 

Section 9.01. Covenant Not To Consolidate, Merge, Sell, Convey, Transfer or Dispose Property except under Certain Conditions.
The Company shall not merge or consolidate with any other Person or sell or convey all or substantially all of its assets to any Person, unless: 

(a) either the Company shall be the surviving Person, or the successor entity (if other than the Company) shall be a corporation duly organized
and existing under the laws of the United States of America, any state thereof or the District of Columbia and such corporation shall expressly assume all of the Company’s responsibilities and liabilities under the Purchase Contracts, the
Corporate Units, the Treasury Units, the Cash Settled Units, this Agreement (including the Pledge provided for herein), and the Remarketing Agreement (if any) by one or more supplemental agreements, in form reasonably satisfactory to
the Purchase Contract Agent and the Collateral Agent, executed and delivered to the Purchase Contract Agent and the Collateral Agent by such corporation; and 

(b) the Company or such successor corporation, as the case may be, shall not, immediately after such merger or consolidation, or such sale or
conveyance, be in default in the performance of any of its obligations or covenants under any of the foregoing agreements. 

Section 9.02. Rights and Duties of Successor Corporation. In case of any such merger, consolidation, sale or conveyance,
and upon any such assumption by a successor corporation in accordance with Section 9.01, such successor corporation shall succeed to and be substituted for the Company with the same effect as if it had been named in
the Purchase Contracts, the Corporate Units, the Treasury Units, the Cash Settled Units, this Agreement (including the Pledge provided for herein), and the Remarketing Agreement (if any), as the Company and (other than in the case of a lease)
the Company shall be relieved of any further obligation under the Purchase Contracts, the Corporate Units, the Treasury Units, the Cash Settled Units, this Agreement (including the Pledge provided for herein), and the Remarketing
Agreement (if any). Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of NiSource Inc. any or all of the Certificates evidencing Units issuable hereunder which theretofore shall
not have been signed by the Company and delivered to the Purchase Contract Agent; and, upon the order of such successor corporation, instead of the Company, and subject to all the terms, conditions and limitations in this Agreement
prescribed, the Purchase Contract Agent shall authenticate and execute on behalf of the Holders as their 

  
 106 

 
attorney-in-fact and deliver any Certificates which previously shall have been signed and delivered by the officers
of the Company to the Purchase Contract Agent for authentication and execution, and any Certificate evidencing Units which such successor corporation thereafter shall cause to be signed and delivered to the Purchase Contract Agent for that
purpose. All the Certificates issued shall in all respects have the same legal rank and benefit under this Agreement as the Certificates theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such
Certificates had been issued at the date of the execution hereof. In case of any such merger, consolidation, sale or conveyance such change in phraseology and form (but not in substance) may be made in the Certificates evidencing Units
thereafter to be issued as may be appropriate. 
 Section 9.03. Officer’s Certificate and Opinion of Counsel
Given to Purchase Contract Agent. The Purchase Contract Agent, subject to Section 7.01 and Section 7.03, shall receive an Officer’s Certificate and an Opinion of Counsel and
may rely thereon as conclusive evidence that any such merger, consolidation, sale or conveyance, and any such assumption, complies with the provisions of this Article 9 and that all conditions precedent to the
consummation of any such merger, consolidation, sale or conveyance have been met. 
 ARTICLE 10 

COVENANTS 

Section 10.01. Performance under Purchase Contracts. The Company covenants and agrees for the benefit of the Holders from
time to time of the Units that it will duly and punctually perform its obligations under the Purchase Contracts in accordance with the terms of the Purchase Contracts and this Agreement. 

Section 10.02. Maintenance of Office or Agency. The Company will maintain in the contiguous United States an office
or agency where Certificates may be presented or surrendered for acquisition of shares of Common Stock upon settlement of the Purchase Contracts on the Purchase Contract Settlement Date, or upon Early Settlement or Fundamental Change Early
Settlement and for transfer of Collateral upon occurrence of a Termination Event, where Certificates may be surrendered for registration of transfer or exchange, or for a Collateral Substitution and where notices and demands to or upon
the Company in respect of the Units and this Agreement may be served. The Company will give prompt written notice to the Purchase Contract Agent of the location, and any change in the location, of such office or agency. The Company initially
designates the Corporate Trust Office of the Purchase Contract Agent as such office of the Company. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Purchase Contract
Agent with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Company hereby appoints the Purchase Contract Agent as its agent to receive all such
presentations, surrenders, notices and demands. 
 The Company may also from time to time designate one or more other offices or agencies where Certificates
may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the 

  
 107 

 
contiguous United States for such purposes. The Company will give prompt written notice to the Purchase Contract Agent of any such designation or rescission and of any change in the
location of any such other office or agency. The Company hereby designates as the place of payment for the Units the Corporate Trust Office and appoints the Purchase Contract Agent at the Corporate Trust Office as paying agent in such
city. 
 Section 10.03. Company to Reserve Common Stock. The Company shall at all times prior to the Purchase Contract
Settlement Date reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock the full number of shares of Common Stock issuable against tender of payment in respect of all Purchase Contracts
constituting a part of the Units evidenced by Outstanding Certificates (including the maximum number of Make-Whole Shares). 

Section 10.04. Covenants as to Common Stock; Listing. (a) The Company covenants that all shares of Common Stock which
may be issued against tender of payment in respect of, or in respect of any Contract Adjustment Payment on, any Purchase Contract constituting a part of the Outstanding Units will, upon issuance, be duly authorized, validly issued,
fully paid and nonassessable. The Company shall comply, in all material respects, with all applicable securities laws regulating the offer, issuance and delivery of shares of Common Stock upon settlement of, or in respect of any Contract
Adjustment Payment on, Purchase Contracts and will issue such shares of Common Stock as freely-tradable shares, except to the extent holders thereof are underwriters (within the meaning of the Securities Act) or Affiliates of the Company.

 (b) The Company further covenants that, if at any time the Common Stock shall be listed on the NYSE or any other national securities
exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated
quotation system, all Common Stock issuable upon settlement of, or issuable in respect of Contract Adjustment Payments on, Purchase Contracts; provided, however, that, if the rules of such exchange or automated quotation system permit
the Company to defer the listing of such Common Stock until the earlier of (i) the date on which any Purchase Contract is first settled in accordance with the provisions of this Agreement and (ii) the first payment of any Contract
Adjustment Payment in shares of Common Stock, the Company covenants to list such Common Stock issuable upon the earlier of (x) settlement of the Purchase Contracts and (y) the first payment of any Contract Adjustment Payment in shares of
Common Stock, in accordance with the requirements of such exchange or automated quotation system no later than at such time. 
 (c)
The Company shall use its commercially reasonable efforts to effect the listing of the Corporate Units on the NYSE within 30 days of the date of the initial issuance of the Corporate Units. 

Section 10.05. ERISA. Each Holder from time to time of the Units hereby represents that (a) the Holder is not
purchasing the Units (and securities underlying the Units) with, or on behalf of, the assets of any Plan or (b) (i) the purchase, holding and disposition of the Units (and securities underlying the Units) satisfies ERISA’s fiduciary
standards and other requirements under ERISA, the Code or other similar requirements under any applicable laws, (ii) the 

  
 108 

 
purchase, holding and disposition of the Units (and the securities underlying the Units) will not result in a non-exempt prohibited transaction under
Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable laws; and (iii) neither the Company nor any of its Subsidiaries nor the Underwriters, are or will be deemed to be a fiduciary with
respect to any Plan. 
 Section 10.06. Tax Treatment. The Company covenants and agrees, for United States federal income

deduct and withhold from any payment or distribution (or deemed distribution) made with respect to a Purchase Contract or any share of or Applicable Ownership Interest in Mandatory Convertible Preferred Stock (or the delivery of shares of Common
Stock and/or cash upon conversion of Mandatory Convertible Preferred Stock or settlement of a Purchase Contract) or with respect to the Applicable Ownership Interests in the Treasury Portfolio or the Treasury Securities such amounts as are required

governmental entity, such deducted or withheld amounts shall be treated for all purposes as having been paid (or delivered) to the applicable Holder. In the event the Company, the Purchase Contract Agent, the Collateral Agent, the Custodial Agent,
the Remarketing Agent or the Securities Intermediary previously remitted any amounts to a governmental entity on account of taxes required to be deducted or withheld in respect of any payment or distribution (or deemed distribution) or delivery with
respect to a Purchase Contract or any share of Mandatory Convertible Preferred Stock with respect to an applicable Holder, the Company, the Purchase Contract Agent, the Collateral Agent, the Custodial Agent, the Remarketing Agent or the Securities
Intermediary, as applicable, shall be entitled to offset any such amounts against any amounts otherwise payable or deliverable to the applicable Holder hereunder or under any other instrument or agreement. 

Section 10.08. Remarketing Agreement. On or prior to the date that is 20 days prior to the first day of the Final

against, all of such Person’s right, title and interest in and to the Collateral, whether now existing or hereafter arising, to secure the prompt and complete payment and performance when due (whether at stated maturity, by acceleration

provision of this Agreement, the Company shall terminate any UCC financing statements that have been filed that relate to such Collateral, and take any other action that the Purchase Contract Agent or any Holder reasonably requests, to evidence the
termination of the Pledge, in each case, at the sole expense of the Company.

 ARTICLE 12 

ADMINISTRATION OF COLLATERAL 

Section 12.01. Initial Deposit of Mandatory Convertible Preferred Stock. (a) Prior to or concurrently with the
execution and delivery of this Agreement, the Company shall cause the Transfer Agent to transfer, on behalf of the Purchase Contract Agent, through the applicable procedures of the Depositary, for credit to the Collateral Account, the
Applicable Ownership Interests in Mandatory Convertible Preferred Stock and the shares of Mandatory Convertible Preferred Stock underlying such Applicable Ownership Interests in Mandatory Convertible Preferred Stock or security entitlements relating
thereto and the Securities Intermediary shall indicate by book-entry that a security entitlement with respect to such Applicable Ownership Interests in Mandatory Convertible Preferred Stock (and the shares of Mandatory Convertible Preferred
Stock underlying such Applicable Ownership Interests in Mandatory Convertible Preferred Stock) has been credited to the Collateral Account. 

(b) The Collateral Agent may, but shall not be obligated to, at any time or from time to time cause any or all securities or other
property underlying any financial assets credited to the Collateral Account to be registered in the name of the Securities Intermediary, the Collateral Agent or their respective nominees. 

Section 12.02. Establishment of Collateral Account. The Securities Intermediary hereby confirms that: 

(a) the Securities Intermediary has established the Collateral Account; 

(b) the Collateral Account is a securities account and a “securities account” as defined in Article 1(b) of the Hague Securities
Convention; 
 (c) subject to the terms of this Agreement, the Securities Intermediary shall identify in its records the Collateral Agent as
the entitlement holder entitled to exercise the rights that comprise any financial asset credited to the Collateral Account; 
 (d) all
property delivered to the Securities Intermediary pursuant to this Agreement, including any Cash, Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities and the Permitted Investments, shall be credited promptly to the
Collateral Account; 
 (e) all securities or other property underlying any financial assets credited to the Collateral Account shall be
(i) registered in the name of the Purchase Contract Agent and indorsed, without recourse or representation, to the Securities Intermediary or in blank, (ii) registered in the name of the Securities Intermediary or
(iii) credited to another securities account maintained in the name of the Securities Intermediary. In no case shall any financial asset credited to the Collateral Account be registered in the name of the Purchase Contract Agent (in its
capacity as such) or any Holder or specially indorsed to the Purchase Contract Agent (in its capacity as such) or any Holder, unless such financial asset has been further indorsed to the Securities Intermediary or in blank; and 

(f) the Securities Intermediary is an “intermediary” (as defined in Article 1(c) of the Hague Securities Convention). 

In addition, the Securities Intermediary hereby confirms and agrees that (i) it is a “securities intermediary” (as defined in Section 8-102(a)(14) of the UCC) in respect of the Collateral Account, and that all properties (except for Cash) credited to the Collateral Account shall be treated as “financial assets” (as defined
in Section 8-102(a)(9) of the UCC), and (ii) with respect to all Cash held, credited, or carried by, in or to the Collateral Account, the Securities Intermediary shall maintain such Collateral
Account as a “deposit account” within the meaning of Section 9-102 of the UCC. The Securities Intermediary confirms that it is acting as a bank within the meaning of Article 9 of the UCC with
respect to any Cash that may be held, credited, or carried by or in the Collateral Account. 
 Section 12.03. Treatment as Financial
Assets. Each item of property (whether investment property, financial asset, security or instrument, but other than Cash) credited to the Collateral Account shall be treated as a financial asset. 

Section 12.04. Sole Control by Collateral Agent. Except as provided in Section 15.01, at all
times prior to the termination of the Pledge, the Collateral Agent shall have sole control of the Collateral Account, and the Securities Intermediary shall take instructions and directions, and comply with entitlement orders, with
respect to the Collateral Account or any financial asset or Cash credited thereto solely from the Collateral Agent as set forth in this Agreement. If at any time the Securities Intermediary shall receive an entitlement order from the
Collateral Agent (acting on the written instruction of the Company) or a written instruction directing the disposition of funds in the Collateral Account issued by the Collateral Agent (acting on the written instruction of the Company) and relating
to the Collateral Account, the Securities Intermediary shall comply with such entitlement order or instruction without further consent by the Purchase Contract Agent or any Holder or any other Person. Except as otherwise permitted
under this Agreement, until termination of the Pledge, the Securities Intermediary shall not comply with any entitlement orders issued by the Purchase Contract Agent or any Holder. 

  
 111 

 Section 12.05. Jurisdiction. The Collateral Account, and the rights and
obligations of the Securities Intermediary, the Collateral Agent, the Purchase Contract Agent and the Holders with respect thereto, shall be governed by the laws of the State of New York. Regardless of any provision in any other
agreement, for the purposes of the UCC the Securities Intermediary’s jurisdiction is the State of New York. As permitted by Article 4 of the Hague Securities Convention, the parties hereto agree that the law of the State of New York shall
govern each of the issues specified in Article 2(1) of the Hague Securities Convention. In addition, to the extent that any agreements between the Securities Intermediary and any other Person governing the Collateral Account (collectively,
the “Account Agreements”) do not provide that the laws of the State of New York shall govern all of the issues specified in Article 2(1) of the Hague Securities Convention, each Account Agreement is hereby amended to provide that
the law applicable to all of the issues specified in Article 2(1) of the Hague Securities Convention shall be the laws of the State of New York. The Securities Intermediary represents that each Account Agreement (a) is governed by the laws of
the State of New York and (b) if any Account Agreement expressly provides that a law is applicable to all the issues specified in Article 2(1) of the Hague Securities Convention, that law is the laws of the State of New York. At the time of its
entry into the governing law provisions of this Agreement, the Securities Intermediary had an office located in the United States that was not a temporary office and that engaged in a business or other regular activity of maintaining securities
accounts. 

  
 112 

 Section 12.06. No Other Claims. Except for the interest of the Collateral
Agent and of the Purchase Contract Agent and the Holders in the Collateral Account, the Securities Intermediary (without having conducted any investigation) does not know of any interest in the Collateral Account or in any Cash or
financial asset credited thereto. If a Responsible Officer of the Securities Intermediary receives written notice that any Person asserts any lien, encumbrance or adverse claim (including any writ, garnishment, judgment, warrant of
attachment, execution or similar process) against the Collateral Account or in any Cash or financial asset carried therein, the Securities Intermediary shall promptly notify the Collateral Agent and the Purchase Contract Agent, and the
Purchase Contract Agent shall notify the Company. 
 Section 12.07. Investment and Release. 

(a) All proceeds of financial assets from time to time credited to the Collateral Account shall be invested and reinvested as provided
in this Agreement. At all times prior to termination of the Pledge, no property shall be released from the Collateral Account except in accordance with this Agreement. 

(b) In the event that any shares of Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory
Convertible Preferred Stock are to be released from the Pledge following a Termination Event, Collateral Substitution, Successful Remarketing, Early Settlement or Fundamental Change Early Settlement (a “Released Share”), and the
Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock are represented by a physical certificate in the name of the Purchase Contract Agent held by the Collateral Agent (the “Pledged Convertible Preferred
Share”), such release and delivery shall be evidenced by an endorsement by the Collateral Agent on the certificate held by the Collateral Agent reflecting a reduction in the number of shares of Mandatory Convertible Preferred Stock
represented by such Pledged Convertible Preferred Share equal in amount (the “Reduced Balance”) to the number of the Released Shares. The Collateral Agent shall confirm any such Reduced Balance by sending via electronic mail or
otherwise delivering a photocopy of such endorsement made on the Pledged Convertible Preferred Share evidencing such Reduced Balance to the Transfer Agent at the address of the Transfer Agent provided for notices to the Transfer Agent in this
Agreement (or at such other address as the Transfer Agent shall provide to the Collateral Agent). Upon receipt of such confirmation, the Transfer Agent shall instruct the Custodial Agent in writing to increase the balance of a Global Preferred Share
held by the Custodial Agent in an amount equal to the Reduced Balance by an endorsement made by the Custodial Agent on such Global Preferred Share to reflect such increase. In the event that a share of Mandatory Convertible Preferred Stock is
transferred to the Collateral Agent pursuant to Section 3.14(a) or Section 3.15(a) (a “Subjected Share”) in connection with the recreation of Corporate Units, such transfer shall
be evidenced by an endorsement by the Collateral Agent on the Pledged Convertible Preferred Share held by the Collateral Agent reflecting an increase in the balance of such Pledged Convertible Preferred Share equal in amount (the “Increased
Balance”) to the number of such Subjected Shares. The Collateral Agent shall confirm any such Increased Balance by sending via electronic mail or otherwise delivering a photocopy of such endorsement made on the Pledged Convertible Preferred
Share evidencing such Increased Balance to the Transfer Agent at the address of the Transfer Agent provided for notices to the Transfer Agent (or at such other address as the Transfer Agent shall provide to the Collateral Agent). Upon receipt of
such confirmation, the Transfer Agent shall instruct the Custodial Agent in writing to decrease the balance of the Global Preferred Share held by the Custodial Agent in an amount equal to the Increased Balance by an endorsement made by the Custodial
Agent on such Global Preferred Share to reflect such decrease. The release and delivery of any Released Share in the case where the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock are represented by a Global Preferred
Share shall be effected by a transfer of such Released Share to an account at the Depositary specified by the holder of such Released Share to the Purchase Contract Agent and Collateral Agent and otherwise in accordance with the terms of the
relevant provision of this Agreement. 

  
 113 

 Section 12.08. Treasury Securities. Promptly following receipt of the
Treasury Securities in substitution of any Mandatory Convertible Preferred Stock underlying Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock upon creation of Treasury Units, the Collateral Agent shall notify the
Company of such receipt of Treasury Securities. 
 Section 12.09. Statements and Confirmations. The Securities
Intermediary shall promptly send copies of all statements, confirmations and other correspondence concerning the Collateral Account and any Cash or financial assets credited thereto simultaneously to each of the Purchase Contract Agent and
the Collateral Agent at their addresses for notices under this Agreement. The requirements of this Section 12.09 shall be performed by the Securities Intermediary by granting online read only access to the Collateral
Account to the extent requested. 
 Section 12.10. Tax Allocations. To the extent required by law, the Purchase Contract Agent
shall timely report all items of income, gain, expense and loss recognized in the Collateral Account to the Internal Revenue Service in the manner required by law. None of the Securities Intermediary, the Collateral Agent and the
Custodial Agent shall have any tax reporting duties hereunder. 
 Section 12.11. No Other Agreements. The Securities
Intermediary, acting solely in its capacity as Securities Intermediary, has not entered into, and prior to the termination of the Pledge shall not enter into, any agreement with any other Person relating to the Collateral Account or any Cash
or financial assets credited thereto, including, without limitation, any agreement to comply with entitlement orders of any Person other than the Collateral Agent. 

Section 12.12. Powers Coupled with an Interest. The rights and powers granted in this Agreement to the Collateral
Agent have been granted in order to perfect its security interests in the Collateral Account, are powers coupled with an interest and will be affected neither by the bankruptcy of the Purchase Contract Agent or any Holder nor by the lapse
of time. The obligations of the Securities Intermediary under this Agreement shall continue in effect until the termination of the Pledge. 

Section 12.13. Waiver of Lien Waiver of Set-off. The Securities Intermediary waives
any security interest, lien or right to make deductions or set-offs that it may now have or hereafter acquire in or with respect to the Collateral Account, any Cash or financial asset credited thereto
or any security entitlement in respect thereof. Neither the Cash or financial assets credited to the Collateral Account nor the security entitlements in respect thereof will be subject to deduction,
set-off, banker’s lien, or any other right in favor of any person other than the Company.

execute and deliver such further documents and do such other acts and things as the Company may reasonably request in order to maintain the Pledge, and the perfection and priority thereof, and to confirm the rights of the Collateral
Agent hereunder. The Purchase Contract Agent shall have no liability to any Holder for the maintenance of the Pledge or the perfection or priority hereof or for executing any documents or for taking any such acts requested by the Company
hereunder, except for liability for its own grossly negligent acts, its own grossly negligent failure to act or its own willful misconduct. 

(e) The Collateral Agent, the Securities Intermediary and the Custodial Agent shall be entitled to all of the rights, protections, privileges

 ARTICLE 14 

REPRESENTATIONS AND WARRANTIES TO COLLATERAL AGENT; HOLDER COVENANTS 

Section 14.01. Representations And Warranties. Each Holder from time to time, acting through the Purchase Contract Agent as
attorney-in-fact (it being understood that the Purchase Contract Agent shall not be liable for any representation or warranty made by or on behalf of a Holder),
hereby represents and warrants to the Collateral Agent and the Company (with respect to such Holder’s interest in the Collateral), which representations and warranties shall be deemed repeated on each day a Holder effects a
Transfer of Collateral, that:

in the Transfer of the Collateral, including the Collateral Agent and the Securities Intermediary, gives the notices and takes the action required of it hereunder and under applicable law for perfection of that interest and assuming the
establishment and exercise of control pursuant to Article 12 hereof); and 

  
 116

ARTICLE 15 
 THE
COLLATERAL AGENT, THE CUSTODIAL AGENT AND THE SECURITIES INTERMEDIARY 
 It is hereby agreed as follows: 

Section 15.01. Appointment, Powers and Immunities. The Company hereby appoints U.S. Bank to act on its behalf as the
Collateral Agent, the Custodial Agent and the Securities Intermediary hereunder, and the Company hereby (i) authorizes each of the Collateral Agent, the Custodial Agent and the Securities Intermediary to take such actions on its behalf and to
exercise such powers on its behalf as are delegated to the Collateral Agent, the Custodial Agent and the Securities Intermediary by the terms hereof and (ii) authorizes and directs the Collateral Agent to take such actions as from time to time
shall be required of the Collateral Agent under the terms of this Agreement and the Certificate of Designations. The Collateral Agent, the Custodial Agent and the Securities Intermediary each hereby agrees to act in its respective capacity as such

Agreement. The Collateral Agent, the Custodial Agent and the Securities Intermediary shall act solely as agent for the Company hereunder (and not as a fiduciary), shall not assume any obligation or relationship of agency or

  
 117 

 
trust for or with any of the Holders, except for the obligations owed by a pledgee of property to the owner of the property under this Agreement and applicable law, and shall have such powers as
are specifically vested in the Collateral Agent, the Custodial Agent and the Securities Intermediary, as the case may be, by the terms of this Agreement. Each Agent’s duties hereunder and under the other documents executed in connection
herewith are solely ministerial and administrative in nature. The Collateral Agent, the Custodial Agent and Securities Intermediary shall: 

(a) have no duties, responsibilities, covenants or obligations except those expressly set forth in this Agreement and no implied covenants,
functions, responsibilities, duties, liabilities or obligations shall be inferred from this Agreement against the Collateral Agent, the Custodial Agent or the Securities Intermediary, nor shall the Collateral Agent, the Custodial Agent
or the Securities Intermediary be bound by the provisions of any agreement by any party hereto beyond the specific terms hereof and none of the Collateral Agent, the Custodial Agent or the Securities Intermediary shall have any fiduciary duty
to the Holders or any other Person, and in acting hereunder, the Collateral Agent, Custodial Agent and Securities Intermediary shall act solely as an agent of the Company and will not thereby assume any obligations towards or relationship of

 (b) not be responsible for any recitals contained in this
Agreement, or in any certificate or other document referred to or provided for in, or received by it under, this Agreement or the Units, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement (other than as against the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be), the Units, any Collateral or any other document referred to or provided for herein or therein or for any
failure by the Company or any other Person (except the Collateral Agent, the Custodial Agent or Securities Intermediary, as the case may be) to perform any of its obligations hereunder or thereunder or, for the perfection, priority or
maintenance of any security interest created hereunder; 
 (c) not be required to initiate or conduct any litigation or collection
proceedings hereunder (except pursuant to directions furnished under Section 15.02 hereof, subject to Section 15.08 hereof); 

(d) not be responsible or liable for any action taken or omitted to be taken by it hereunder or under any other document or instrument referred

by a court of competent jurisdiction; 
 (e) not be required to advise any party as to selling or retaining, or taking or refraining
from taking any action with respect to, any securities or other property deposited hereunder; 

  
 118 

 (f) not incur any liability for not performing any act or fulfilling any duty, obligation or
responsibility hereunder by reason of any occurrence beyond the control of the Collateral Agent, the Custodial Agent or the Securities Intermediary (including but not limited to any act or provision of any present or future law or regulation or
governmental authority, any act of God or war, civil unrest, local or national disturbance or disaster, any act of terrorism, or the unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility); and 

(g) the obligations of the Purchase Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary under this
Agreement are several and not joint. 
 Subject to the foregoing, during the term of this Agreement, the Collateral Agent, the Custodial Agent and the
Securities Intermediary shall take all reasonable action in connection with the safekeeping and preservation of the Collateral hereunder as determined by industry standards. The Collateral Agent, the Securities Intermediary and the Custodial
Agent shall not be responsible for and make no representation as to the existence, genuineness, value or protection of any Collateral, for the legality, effectiveness or sufficiency of any security document, or for the creation, perfection, filing,
priority, sufficiency or protection of any liens securing the Mandatory Convertible Preferred Stock and the Collateral. 
 The Collateral Agent, the
Custodial Agent and the Securities Intermediary shall only be responsible for transferring money, securities or other property in accordance with the terms herein to the extent that such money, securities or other property is credited to the
Collateral Account. 
 No provision of this Agreement or any Certificate shall require the Collateral Agent, the Custodial Agent or the Securities
Intermediary to expend or risk its own funds or otherwise incur any liability, financial or otherwise, in the performance of any of its duties or the exercise of any of its rights or powers hereunder. In no event shall the Collateral
Agent, the Custodial Agent or the Securities Intermediary be liable for any amount in excess of the Value of the Collateral. 

Section 15.02. Instructions of the Company. The Company shall have the right, by one or more written instruments executed
and delivered to the Collateral Agent, to direct the time, method and place of conducting any proceeding for the realization of any right or remedy available to the Collateral Agent, or of exercising any power conferred on the
Collateral Agent, or to direct the taking or refraining from taking of any action authorized by this Agreement; provided, however, that (a) such direction shall not conflict with the provisions of any law or of this Agreement or
involve the Collateral Agent in personal liability and (b) the Collateral Agent shall be indemnified and/or provided with security to its satisfaction as provided herein. Nothing contained in this Section 15.02
shall impair the right of the Collateral Agent to take any action or omit to take any action which it deems proper and which is not inconsistent with such direction. None of the Collateral Agent, the Custodial Agent or the Securities
Intermediary has any obligation or responsibility to file UCC financing or continuation statements or amendments or to take any other actions to create, preserve or maintain the security interest in the Collateral. 

Section 15.03. Reliance by Collateral Agent, Custodial Agent and Securities Intermediary. Each of the Securities
Intermediary, the Custodial Agent and the Collateral Agent (solely for purposes of this paragraph, the “Agents”) shall be entitled to rely conclusively upon any certification, order, judgment, opinion, notice or other written
communication (including, without limitation, any thereof by e-mail or similar electronic means, telecopy or facsimile) 

  
 119 

 
believed by it in good faith to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons (without being required to determine the correctness of any
fact stated therein) and consult with and conclusively rely upon advice, opinions and statements of legal counsel and other experts selected by the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be, in each
case, at the expense of the Company. As to any matters not expressly provided for by this Agreement, the Collateral Agent, the Custodial Agent and the Securities Intermediary shall in all cases be fully protected in acting, or in refraining from
acting, hereunder in accordance with instructions given by the Company or the Holders, as the case may be, or by another Agent, as the case may, be in accordance with the terms of this Agreement; provided, however, it is understood
that in all cases the Agent shall be fully justified in failing or refusing to take any such action under this Agreement if it shall not have received such direction from the Company or the Holders (acting in accordance with this Agreement) or from
another Agent (acting in accordance with this Agreement), as such Agent deems appropriate. This provision is intended solely for the benefit of the Agents and their successors and permitted assigns and is not intended to and will not entitle the
other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto. 
 In each case that the Collateral Agent,
the Custodial Agent or the Securities Intermediary may or is required hereunder to take any action, including without limitation to make any determination or judgment, to give consents, to exercise rights, powers or remedies, to release or
sell Collateral or otherwise to act hereunder, the Collateral Agent, the Custodial Agent or Securities Intermediary may seek direction from the Company. The Collateral Agent, the Custodial Agent or Securities Intermediary shall not be
liable with respect to any action taken or omitted to be taken by it in accordance with the direction from the Company. Unless direction or otherwise is expressly provided herein, if the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall request direction from the Company with respect to any action, the Collateral Agent, the Custodial Agent or the Securities Intermediary shall be entitled to refrain from such action unless and until such
agent shall have received direction from the Company, and the agent shall not incur liability to any Person by reason of so refraining. 

Section 15.04. Certain Rights. (a) Whenever in the administration of the provisions of this Agreement the Collateral Agent,
the Custodial Agent or the Securities Intermediary shall deem it necessary or desirable that a matter be proved or established prior to taking, or omitting to take, or suffering any action to be taken hereunder, such matter (unless other evidence in
respect thereof be herein specifically prescribed) may, in the absence of gross negligence, bad faith or willful misconduct on the part of the Collateral Agent, the Custodial Agent or the Securities Intermediary, be deemed to be conclusively proved
and established by an Officer’s Certificate, and delivered to the Collateral Agent, the Custodial Agent or the Securities Intermediary and such certificate, in the absence of bad faith on the part of the Collateral Agent, the Custodial Agent or
the Securities Intermediary, shall be full warrant to the Collateral Agent, the Custodial Agent or the Securities Intermediary for any action taken, suffered or omitted by it under the provisions of this Agreement upon the faith thereof. 

(b) The Collateral Agent, the Custodial Agent or the Securities Intermediary shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, entitlement order, approval or other paper or document. 

  
 120 

 (c) The authorizations, rights, privileges, protections and benefits given to each of the
Collateral Agent, the Custodial Agent or the Securities Intermediary are extended to, and shall be enforceable by, each such Collateral Agent, the Custodial Agent or the Securities Intermediary, under any document to which it is a party (as
applicable). In the event any claim of inconsistency between this Agreement and the terms of any other document arises with respect to the duties, liabilities and rights of the Collateral Agent, the Custodial Agent or the Securities Intermediary,
the terms of this Agreement shall control. 
 Section 15.05. Merger, Conversion, Consolidation or Succession to Business.
Any Person into which the Collateral Agent, the Custodial Agent or the Securities Intermediary may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to
which the Collateral Agent, the Custodial Agent or the Securities Intermediary shall be a party, or any Person succeeding to all or substantially all of the corporate trust business of the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall be the successor of the Collateral Agent, the Custodial Agent or the Securities Intermediary, provided such Person shall be otherwise qualified and eligible under this Article 15
hereunder without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto except where an instrument of transfer or assignment is required by law to effect such succession,
anything herein to the contrary notwithstanding. 
 Section 15.06. Rights in Other Capacities. The Collateral Agent, the
Custodial Agent and the Securities Intermediary and their affiliates may (without having to account therefor to the Company) accept deposits from, lend money to, make their investments in and generally engage in any kind of banking,
trust or other business with the Company, the Purchase Contract Agent, any other Person interested herein and any Holder (and any of their respective subsidiaries or affiliates) as if it were not acting as the Collateral Agent, the Custodial
Agent or the Securities Intermediary, as the case may be, and the Collateral Agent, the Custodial Agent, the Securities Intermediary and their affiliates may accept fees and other consideration from the Company, the Purchase Contract
Agent and any Holder without having to account for the same to the Company; provided that each of the Collateral Agent, the Custodial Agent and the Securities Intermediary covenants and agrees with the Company that it shall not
accept, receive or permit there to be created in favor of itself and shall take no affirmative action to permit there to be created in favor of any other Person, any security interest, lien or other encumbrance of any kind in or upon the
Collateral other than the lien created by the Pledge. 
 Section 15.07. Non-reliance on
the Collateral Agent, Custodial Agent and Securities Intermediary. None of the Collateral Agent, the Custodial Agent and the Securities Intermediary shall be required to keep itself informed as to the performance or
observance by the Purchase Contract Agent or any Holder of this Agreement, the Units or any other document referred to or provided for herein or therein or to inspect the properties or books of the Purchase Contract Agent or any
Holder. None of the Collateral Agent, the Custodial Agent or the Securities Intermediary shall have any duty or responsibility to provide the Company with any credit or other information concerning the affairs, financial condition or business
of the Purchase Contract Agent or any Holder (or any of their respective affiliates) that may come into the possession of the Collateral Agent, the Custodial Agent or the Securities Intermediary or any of their respective affiliates.

  
 121 

 Section 15.08. Compensation And Indemnity. The Company agrees to: 

(a) pay the Collateral Agent, the Custodial Agent and the Securities Intermediary from time to time such compensation as shall be agreed in
writing between the Company and the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be, for all services rendered by them hereunder; 

(b) indemnify and hold harmless the Collateral Agent, the Custodial Agent, the Securities Intermediary and each of their respective affiliates,
directors, officers, agents and employees (collectively, the “Pledge Indemnitees”), from and against any and all claims (whether asserted by the Company, the Purchase Contract Agent or any other Person), liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs and reasonable expenses (including reasonable fees and expenses of counsel) (collectively, “Losses” and individually, a “Loss”) that
may be imposed on, incurred by, or asserted against, the Pledge Indemnitees or any of them for following any instructions, acting upon any notices or other directions (which shall include an instruction, notice or direction not to act)
upon which any of the Collateral Agent, the Custodial Agent or the Securities Intermediary is entitled to conclusively rely pursuant to the terms of this Agreement, provided that the Collateral Agent, the Custodial Agent or the
Securities Intermediary has not acted with gross negligence or engaged in willful misconduct (as adjudicated by a court of competent jurisdiction in a final, non-appealable decision) with respect to the
specific Loss against which indemnification is sought; and 
 (c) in addition to and not in limitation of
Section 15.08(b), indemnify and hold the Pledge Indemnitees and each of them harmless from and against any and all Losses that may be imposed on, incurred by or asserted against, the Pledge Indemnitees or any of them
in connection with or arising out of the Collateral Agent’s, the Custodial Agent’s or the Securities Intermediary’s acceptance or performance of its rights, powers and duties under this Agreement, including but not
limited to the rights and powers set forth in Section 15.09, provided the Collateral Agent, the Custodial Agent or the Securities Intermediary has not acted with gross negligence or engaged in willful misconduct (as
adjudicated by a court of competent jurisdiction in a final, non-appealable decision) with respect to the specific Loss against which indemnification is sought, including the Pledge Indemnitee’s
reasonable out-of-pocket costs and expenses of defending themselves against any claim or liability (whether asserted by the Company, any holder of Units, or otherwise)
in connection with the exercise or performance of any of the Collateral Agent’s, the Custodial Agent’s or Securities Intermediary’s powers or duties hereunder or thereunder or of enforcing the provisions of this Section 15.08 and
Section 15.14. 
 The provisions of this Section 15.08 and Section 15.14 shall survive the
resignation or removal of the Collateral Agent, the Custodial Agent or the Securities Intermediary and the termination of this Agreement. 

Section 15.09. Failure to Act. In the event that, in the good faith belief of the Collateral Agent, the Custodial Agent or
the Securities Intermediary, an ambiguity in the provisions of this Agreement arises or any actual dispute between or conflicting claims by or among the parties hereto or any other Person with respect to any funds or property deposited
hereunder has been asserted in writing, then at its sole option, each of the Collateral Agent, the Custodial Agent and 

  
 122 

 
the Securities Intermediary shall be entitled, after prompt notice to the Company and the Purchase Contract Agent, to refuse to comply with any and all claims, demands or instructions with
respect to such property or funds so long as such dispute or conflict shall continue, and the Collateral Agent, the Custodial Agent and the Securities Intermediary, as the case may be, shall not be or become liable in any way to any of the
parties hereto for its failure or refusal to comply with such conflicting claims, demands or instructions. The Collateral Agent, the Custodial Agent and the Securities Intermediary shall be entitled to refuse to act until either: 

(a) such conflicting or adverse claims or demands shall have been finally determined by a court of competent jurisdiction or settled by
agreement between the conflicting parties as evidenced in a writing satisfactory to the Collateral Agent, the Custodial Agent or the Securities Intermediary; or 

(b) the Collateral Agent, the Custodial Agent or the Securities Intermediary shall have received security and/or an indemnity satisfactory to
it sufficient to hold it harmless from and against any and all loss, claim, liability or reasonable out-of-pocket expense which it may without gross negligence or
willful misconduct incur by reason of its acting. 
 The Collateral Agent, the Custodial Agent and the Securities Intermediary may in addition elect
to commence an interpleader action or seek other judicial relief or orders as the Collateral Agent, the Custodial Agent or the Securities Intermediary may deem necessary. Notwithstanding anything contained herein to the contrary, none
of the Collateral Agent, the Custodial Agent or the Securities Intermediary shall be required to take any action that is in its opinion contrary to law or to the terms of this Agreement, or which would in its opinion subject it or any of its
officers, employees or directors to liability. 
 Section 15.10. Resignation of Collateral Agent, the Custodial Agent and the
Securities Intermediary. (a) Subject to the appointment and acceptance of a successor Collateral Agent, Custodial Agent or Securities Intermediary as provided below: 

(i) the Collateral Agent, the Custodial Agent or the Securities Intermediary may resign at any time by giving notice thereof
to the Company and the Purchase Contract Agent as attorney-in-fact for the Holders; 

(ii) the Collateral Agent, the Custodial Agent or the Securities Intermediary may be removed at any time by the Company upon
written notice thereof; and 
 (iii) if the Collateral Agent, the Custodial Agent or the Securities Intermediary fails to
perform any of its material obligations hereunder in any material respect for a period of not less than 20 calendar days after receiving written notice of such failure by the Purchase Contract Agent and such failure shall be
continuing, the Collateral Agent, the Custodial Agent and the Securities Intermediary may be removed by the Purchase Contract Agent, acting at the direction of the Holders of a majority in number of the Outstanding Units. 

  
 123 

 The Purchase Contract Agent shall promptly notify the Company upon the transmission of notice as
contemplated by Section 15.10(a)(iii) and any removal of the Collateral Agent, the Custodial Agent or the Securities Intermediary pursuant to Section 15.10(a)(iii). Upon any such resignation
or removal, the Company shall have the right to appoint a successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be. If no successor Collateral Agent, Custodial Agent or Securities Intermediary shall have been
so appointed and shall have accepted such appointment within 45 calendar days after the retiring Collateral Agent’s, Custodial Agent’s or Securities Intermediary’s giving of notice of resignation or the Company’s or
the Purchase Contract Agent’s giving notice of such removal, then the retiring or removed Collateral Agent, Custodial Agent or Securities Intermediary may petition any court of competent jurisdiction, at the expense of the Company, for
the appointment of a successor Collateral Agent, Custodial Agent or Securities Intermediary. The Collateral Agent, the Custodial Agent and the Securities Intermediary shall each be a bank, banking corporation or a national banking
association which has an office (or an agency office) in New York City with a combined capital and surplus of at least $50,000,000. Upon the acceptance of any appointment as Collateral Agent, Custodial Agent or Securities Intermediary
hereunder by a successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, such successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, Custodial Agent or Securities Intermediary, as the case may be, and the retiring Collateral Agent, Custodial Agent or Securities Intermediary,
as the case may be, shall take all appropriate action, subject to payment of any amounts then due and payable to it hereunder, to transfer any money and property held by it hereunder (including the Collateral) to such successor. The
retiring Collateral Agent, Custodial Agent or Securities Intermediary shall, upon such succession, be discharged from its duties and obligations as Collateral Agent, Custodial Agent or Securities Intermediary hereunder. After any retiring
Collateral Agent’s, Custodial Agent’s or Securities Intermediary’s resignation hereunder as Collateral Agent, Custodial Agent or Securities Intermediary, the provisions of this Article 15 shall
continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Collateral Agent, the Custodial Agent or the Securities Intermediary. Any resignation or removal of the
Collateral Agent, the Custodial Agent or the Securities Intermediary hereunder, at a time when such Person is also acting as the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be, shall be deemed for all
purposes of this Agreement as the simultaneous resignation or removal of the Collateral Agent, the Securities Intermediary or the Custodial Agent, as the case may be. 

Section 15.11. Right to Appoint Agent or Advisor. The Collateral Agent shall have the right to appoint agents or advisors
in connection with any of its duties hereunder, and the Collateral Agent shall not be liable for any action taken or omitted by, or in conclusive reliance upon the advice of, such agents or advisors selected in good faith. 

Section 15.12. Survival. The provisions of this Article 15 shall survive termination of this
Agreement and the resignation or removal of the Collateral Agent, the Custodial Agent or the Securities Intermediary. 

Section 15.13. Exculpation. Anything contained in this Agreement to the contrary notwithstanding, in no event shall the
Collateral Agent, the Custodial Agent or the Securities Intermediary or their officers, directors, employees or agents be liable under this Agreement for indirect, special, punitive, or consequential loss or damage of any kind
whatsoever, including, but not limited to, lost profits, goodwill, reputation, business opportunity or anticipated saving, whether or not the likelihood of such loss or damage was known to the Collateral Agent, the Custodial Agent or the
Securities Intermediary, or any of them and regardless of the form of action. 

  
 124 

 Section 15.14. Expenses, Etc. The Company agrees to reimburse the Collateral
Agent, the Custodial Agent and the Securities Intermediary for: 
 (a) all reasonable out-of-pocket costs and expenses of the Collateral Agent, the Custodial Agent and the Securities Intermediary (including, without limitation, the reasonable fees and expenses of counsel to the
Collateral Agent, the Custodial Agent and the Securities Intermediary), in connection with (i) the negotiation, preparation, execution and delivery or performance of this Agreement and (ii) any modification, supplement or waiver of
any of the terms of this Agreement; 
 (b) all costs, fees and expenses of the Collateral Agent, the Custodial Agent and the Securities
Intermediary (including, without limitation, reasonable fees and expenses of counsel) in connection with (i) any enforcement or proceedings resulting or incurred in connection with causing any Holder to satisfy its obligations
under the Purchase Contracts forming a part of the Units and (ii) the enforcement of this Section 15.14 and Section 15.08; 

(c) all transfer, stamp, documentary or other similar taxes, assessments or charges (including any interest and penalties thereon or in
connection therewith) levied by any governmental or revenue authority in respect of this Agreement or any other document referred to herein and all costs, expenses, taxes, assessments and other charges incurred in connection with any
filing, registration, recording or perfection of any security interest contemplated hereby; and 
 (d) all reasonable fees and
expenses of any agent or advisor appointed by the Collateral Agent.

Agent may reasonably require, of the names and addresses of the Holders of Units as of a date not more than 15 calendar days prior to the delivery thereof, and (ii) at such other times as the Purchase Contract Agent may request in
writing, within 30 calendar days after the receipt by the Company of any such request, a list of similar form and content as of a date not more than 15 calendar days prior to the time such list is furnished, excluding from any such list
names and addresses previously received by the Purchase Contract Agent. 
 Section 16.02. Preservation of Information;
Communications to Holders. The Purchase Contract Agent shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list furnished to the Purchase Contract Agent

Section 16.01(a) upon receipt of a new list so furnished. 

  
 125 

 Section 16.03. Defaults, Waiver. The Holders of a majority of the
Outstanding Purchase Contracts voting together as one class may, by vote or consent, on behalf of all of the Holders, waive any past default by the Company and its consequences, except a default: 

(a) in the payment on any Purchase Contract, or 

(b) in respect of a provision hereof which under Section 8.02 cannot be modified or amended without the consent of
the Holder of each Outstanding Purchase Contract affected. 
 Upon such waiver, any such default shall cease to exist, and any default by the Company
arising therefrom shall be deemed to have been cured, for every purpose of this Agreement, but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 16.04. Purchase Contract Agent’s Knowledge of Defaults. The Purchase Contract Agent shall not be
deemed to have notice or be charged with knowledge of any Fundamental Change, Termination Event or any default hereunder unless a Responsible Officer of the Purchase Contract Agent has received written notice from the Company or any Holder of such
Fundamental Change, Termination Event or default at the Corporate Trust Office of the Purchase Contract Agent, and such notice references the Company, the Units and this Agreement and identifies such default. 

Section 16.05. Security Interest Absolute. All rights of the Collateral Agent and security interests hereunder, and all
obligations of the Holders from time to time hereunder pursuant to the Pledge, shall be absolute and unconditional irrespective of: 
 (a)
any lack of validity or enforceability of any provision of the Purchase Contracts or the Units or any other agreement or instrument relating thereto; 

(b) any change in the time, manner or place of payment of, or any other term of, or any increase in the amount of, all or any of the
obligations of Holders of the Units under the related Purchase Contracts, or any other amendment or waiver of any term of, or any consent to any departure from any requirement of, this Agreement or any Purchase Contract or any other
agreement or instrument relating thereto; or 
 (c) any other circumstance which might otherwise constitute a defense available to, or
discharge of, a borrower, a guarantor or a pledgor. 
 Section 16.06. Notice of Termination Event. Upon the occurrence of
a Termination Event, the Company shall deliver written notice to the Purchase Contract Agent, the Collateral Agent and the Securities Intermediary. 

  
 126 

 Section 16.07. U.S.A. Patriot Act. In order to comply with the laws, rules,
regulations and executive orders in effect from time to time applicable to banking institutions, including, without limitation, those relating to the funding of terrorist activities and money laundering, including Section 326 of the USA PATRIOT

Contract Agent, the Collateral Agent, the Custodial Agent and the Securities Intermediary to comply with Applicable AML Law.

Series A Corporate Units 
 This Corporate Units
Certificate certifies that [______] is the registered Holder of the number of Corporate Units set forth above [For inclusion in Global Certificates only—or such other number of Corporate Units reflected in the Schedule of Increases or Decreases
in Global Certificate attached hereto], which number, taken together with the number of all other Outstanding Corporate Units and the number of all Outstanding Treasury Units and Outstanding Cash Settled Units, shall not exceed 8,625,000. Each
Corporate Unit consists of (i) an Applicable Ownership Interest in Mandatory Convertible Preferred Stock or an Applicable Ownership Interest in the Treasury Portfolio, subject to the Pledge thereof by such Holder pursuant to the Purchase
Contract and Pledge Agreement and (ii) the rights and obligations of the Holder under one Purchase Contract with the Company. 
 All capitalized terms
used herein without definition herein and that are defined in the Purchase Contract and Pledge Agreement (as defined on the reverse hereof) have the meaning set forth therein. 

In the event of any inconsistency between the provisions of this Corporate Units Certificate and the provisions of the Purchase Contract and Pledge Agreement,
the provisions of the Purchase Contract and Pledge Agreement shall govern and control. 
 Pursuant to the Purchase Contract and Pledge Agreement, the
Applicable Ownership Interest in Mandatory Convertible Preferred Stock or the Applicable Ownership Interest in the Treasury Portfolio, as the case may be, constituting part of each Corporate Unit evidenced hereby has been pledged to the Collateral
Agent, for the benefit of the Company, to secure the obligations of the Holder under the Purchase Contract comprising part of such Corporate Unit. 
 All
payments, if any, with respect to the Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock or all payments with respect to the Pledged Applicable Ownership Interests in
the Treasury Portfolio, as the case may be, constituting part of the Corporate Units shall be paid on the dates and in the manner set forth in the Purchase Contract and Pledge Agreement. 

The Company shall pay, on each Contract Adjustment Payment Date, in respect of each Purchase Contract forming part of a Corporate Unit evidenced hereby, an
amount (the “Contract Adjustment Payments”) equal to 7.75% per year of the Stated Amount for the period from and including the immediately preceding Contract Adjustment Payment Date on which Contract Adjustment Payments were paid
(or if none, April 19, 2021) to but excluding such Contract Adjustment Payment Date. Such Contract Adjustment Payments shall be payable in cash, shares of Common Stock or a combination thereof, at the Company’s election, to the Person in
whose name this Corporate Units Certificate is registered at the close of business on the Record Date for such Contract Adjustment Payment Date. The Company may, at its option, defer such Contract Adjustment Payments as described in the Purchase
Contract and Pledge Agreement. The Contract Adjustment Payments are unsecured and will rank subordinate and junior in right of payment to all of the Company’s existing and future Indebtedness. 

  
 A-2 

 Each Purchase Contract evidenced hereby obligates the Holder of this Corporate Units Certificate to
purchase, and the Company to sell, on the Purchase Contract Settlement Date at a Purchase Price equal to the Stated Amount, a number of newly-issued shares of Common Stock of the Company, equal to the Settlement Rate, unless on or prior to the
Purchase Contract Settlement Date there shall have occurred a Termination Event, an Early Settlement or a Fundamental Change Early Settlement with respect to such Purchase Contract, all as provided in the Purchase Contract and Pledge Agreement. The
Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby, if not paid earlier, shall be paid on the Purchase Contract Settlement Date by application of payment received in the Final Remarketing of
the shares of Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock equal to $1,000 per each such share thereof or the Proceeds of the Pledged Applicable Ownership
Interests in the Treasury Portfolio, as the case may be, pledged to secure the obligations under such Purchase Contract of the Holder of the Corporate Units of which such Purchase Contract is a part. 

If the book-entry system for the Corporate Units has been terminated, the Contract Adjustment Payments paid in cash will be payable, at the option of the
Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or by wire transfer to the account designated by such Person by prior written notice to the Purchase
Contract Agent, given at least ten calendar days prior to the Contract Adjustment Payment Date. 
 Each Purchase Contract evidenced hereby obligates the
Holder and the Beneficial Owner to agree, for United States federal income tax purposes, to (i) treat the Beneficial Owner’s acquisition of the Corporate Units as an acquisition of the Mandatory Convertible Preferred Stock and Purchase
Contract constituting each Corporate Unit, (ii) treat the Applicable Ownership Interests in Mandatory Convertible Preferred Stock as equity of the Company (iii) allocate, as of the date hereof, 100% of the purchase price for a Corporate
Unit to the Applicable Ownership Interests in Mandatory Convertible Preferred Stock and 0% to each Purchase Contract, which will establish the Beneficial Owner’s initial tax basis in each Purchase Contract as $0 and the Beneficial Owner’s
initial tax basis in each Applicable Ownership Interest in Mandatory Convertible Preferred Stock as $100 and (iv) treat the Beneficial Owner as the owner of the applicable interests in the Collateral Account, including the Mandatory Convertible
Preferred Stock. 
 Reference is hereby made to the further provisions set forth on the reverse hereof, which further provisions shall for all purposes have
the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the Purchase Contract Agent by manual
or electronic signature, this Corporate Units Certificate shall not be entitled to any benefit under the Purchase Contract and Pledge Agreement or be valid or obligatory for any purpose.

 (REVERSE OF CORPORATE UNITS CERTIFICATE) 

Each Purchase Contract evidenced hereby is governed by a Purchase Contract and Pledge Agreement, dated as of April 19, 2021 (as may be supplemented from
time to time, the “Purchase Contract and Pledge Agreement”), between the Company and U.S. Bank National Association, as Purchase Contract Agent (in such capacity, including its successors thereunder, the “Purchase Contract
Agent”), and as Collateral Agent, Custodial Agent and Securities Intermediary (in such capacities, including its successors thereunder, the “Collateral Agent”), to which Purchase Contract and Pledge Agreement and
supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Purchase Contract Agent, the Collateral Agent, the Company, and the
Holders and of the terms upon which the Corporate Units Certificates are, and are to be, executed and delivered. 
 Each Purchase Contract evidenced hereby
obligates the Holder of this Corporate Units Certificate to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount, a number of shares of Common Stock equal to the Settlement Rate, unless an
Early Settlement, a Fundamental Change Early Settlement or a Termination Event with respect to the Unit of which such Purchase Contract is a part shall have occurred. 

No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in Section 5.07 of the
Purchase Contract and Pledge Agreement. 
 Each Purchase Contract evidenced hereby that is settled through Early Settlement or Fundamental Change Early
Settlement shall obligate the Holder of the related Corporate Units to purchase at the Purchase Price, and the Company to sell, a number of newly-issued shares of Common Stock determined pursuant to the Purchase Contract and Pledge Agreement. 

In accordance with the terms of the Purchase Contract and Pledge Agreement, unless a Termination Event shall have occurred, the Holder of this Corporate Units
Certificate shall pay the Purchase Price for the shares of Common Stock to be purchased pursuant to each Purchase Contract evidenced hereby by effecting an Early Settlement or, if applicable, a Fundamental Change Early Settlement or from the
proceeds of the Applicable Ownership Interests in the Treasury Portfolio or from the proceeds of the Final Remarketing of the Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible
Preferred Stock. 
 As provided in the Purchase Contract and Pledge Agreement, upon the occurrence of an Unsuccessful Final Remarketing as of the Purchase
Contract Settlement Date, each Holder of any Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock shall be deemed to have automatically delivered the related Mandatory Convertible Preferred Stock to the Company in
satisfaction of such Holder’s obligations under the related Purchase Contracts, as described in Section 5.02(b)(viii) of the Purchase Contract and Pledge Agreement, unless such Holder elects otherwise. 

The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder
unless it shall have received payment of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder in the manner set forth in the Purchase Contract and Pledge Agreement. 

  
 A-6 

 Each Purchase Contract evidenced hereby and all obligations and rights of the Company and the Holder
thereunder, including, without limitation, the rights of the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments, shall terminate if a Termination Event shall occur. Upon the occurrence of a Termination
Event, the Company shall give written notice to the Purchase Contract Agent, the Collateral Agent and to the Holders, at their addresses as they appear in the Security Register. Upon and after the occurrence of a Termination Event, the Collateral
Agent shall release the Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in Mandatory Convertible Preferred Stock or the Applicable Ownership Interests in the Treasury Portfolio forming a part of each
Corporate Unit from the Pledge. A Corporate Unit shall thereafter represent the right to receive the Mandatory Convertible Preferred Stock underlying the Applicable Ownership Interest in Mandatory Convertible Preferred Stock or the Applicable
Ownership Interests in the Treasury Portfolio in accordance with the terms of the Purchase Contract and Pledge Agreement. 
 Under the terms of the Purchase
Contract and Pledge Agreement, the Purchase Contract Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in
Mandatory Convertible Preferred Stock, but only to the extent instructed in writing by the Holders. Upon receipt of notice of any meeting at which holders of Mandatory Convertible Preferred Stock are entitled to vote or upon any solicitation of
consents, waivers or proxies of holders of Mandatory Convertible Preferred Stock, the Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage pre-paid, to the Holders of
Corporate Units the notice required by the Purchase Contract and Pledge Agreement. 
 The Corporate Units Certificates are issuable only in registered form
and only in denominations of a single Corporate Unit and any integral multiple thereof. The transfer of any Corporate Units Certificate will be registered and Corporate Units Certificates may be exchanged as provided in the Purchase Contract and
Pledge Agreement. A Holder who elects to substitute Treasury Securities or Cash for the Mandatory Convertible Preferred Stock thereby creating Treasury Units or Cash Settled Units, shall be responsible for any taxes, governmental charges or other
fees or expenses payable in connection therewith. Except as provided in the Purchase Contract and Pledge Agreement, such Corporate Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Corporate
Unit in respect of the Mandatory Convertible Preferred Stock and Purchase Contract constituting such Corporate Unit may be transferred and exchanged only as a Corporate Unit. 

Subject to, and in compliance with, the conditions and terms set forth in the Purchase Contract and Pledge Agreement, the Holder of Corporate Units may effect
a Collateral Substitution. From and after such Collateral Substitution, each Unit for which Pledged Treasury Securities secure the Holder’s obligations under the Purchase Contract shall be referred to as a “Treasury Unit”, and
each Unit for which Pledged Cash secures the Holder’s obligations under the Purchase Contract shall be referred to as a “Cash Settled Unit”. A Holder may make such Collateral Substitution only in integral multiples of 10
Corporate Units for 10 Treasury Units or 10 Cash Settled Units, as the case may be. 

  
 A-7 

 Subject to and upon compliance with the provisions of, and certain exceptions described in, the Purchase
Contract and Pledge Agreement, at the option of the Holder thereof, Purchase Contracts underlying Units may be settled early by effecting an Early Settlement or a Fundamental Change Early Settlement as provided in the Purchase Contract and Pledge
Agreement. 
 Upon registration of transfer of this Corporate Units Certificate, the transferee shall be bound (without the necessity of any other action on
the part of such transferee, except as may be required by the Purchase Contract Agent pursuant to the Purchase Contract and Pledge Agreement), under the terms of the Purchase Contract and Pledge Agreement and the Purchase Contracts evidenced hereby
and the transferor shall be released from the obligations under the Purchase Contracts evidenced by this Corporate Units Certificate. The Company covenants and agrees, and the Holder, by its acceptance hereof, likewise covenants and agrees, to be
bound by the provisions of this paragraph. 
 The Holder of this Corporate Units Certificate, by its acceptance hereof, irrevocably appoints the Purchase
Contract Agent to enter into and perform the related Purchase Contracts forming part of the Corporate Units evidenced hereby, the Purchase Contract and Pledge Agreement and the Remarketing Agreement identified therein, as the same may be amended,
amended and restated, supplemented or otherwise modified or replaced from time to time (the “Remarketing Agreement”), on its behalf and in its name as its
attorney-in-fact and the Holder of this Corporate Units Certificate hereby authorizes the Purchase Contract Agent to take such actions on its behalf and to exercise such
powers as are delegated to the Purchase Contract Agent by the terms of the Purchase Contract and Pledge Agreement, the Remarketing Agreement, or under any other document or instrument referred to or provided for herein or in connection herewith;
expressly withholds any consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code, agrees to be bound by the terms and
provisions thereof and the Corporate Units evidenced hereby (including, but not limited to, the terms and provisions of the Purchase Contract and Pledge Agreement) for so long as it remains of a Holder of such Unit, covenants and agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract and Pledge Agreement, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract and Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Applicable Ownership Interests in Mandatory Convertible Preferred Stock and the underlying Mandatory Convertible
Preferred Stock or the Applicable Ownership Interests in the Treasury Portfolio, as the case may be, underlying this Corporate Units Certificate pursuant to the Purchase Contract and Pledge Agreement. The Holder further covenants and agrees that, to
the extent and in the manner provided in the Purchase Contract and Pledge Agreement, but subject to the terms thereof, any payments with respect the Mandatory Convertible Preferred Stock underlying the Pledged Applicable Ownership Interests in
Mandatory Convertible Preferred Stock or the Proceeds of the Applicable Ownership Interests in the Treasury Portfolio, as the case may be, on the Purchase Contract Settlement Date equal to the aggregate Purchase Price for the related Purchase
Contracts shall be paid by the Collateral Agent to the Company in satisfaction of such Holder’s obligations under the related Purchase Contracts and such Holder shall acquire no right, title or interest in such payments. The Holder of this
Corporate Units Certificate hereby accepts the authorizations, appointments, acknowledgments and other actions taken by the Purchase Contract Agent in accordance with the Purchase 

  
 A-8 

 
Contract and Pledge Agreement, the Remarketing Agreement or any other document or instrument referred to or provided for or in connection with the Purchase Contract and Pledge Agreement. Upon
U.S. Bank’s receipt of any initial direction, notice or instruction hereunder, any further instruction, notice or direction that U.S. Bank is required to make to U.S. Bank in its other capacities under the terms of this Agreement shall be
deemed by the Holder of this Corporate Units Certificate as being made by U.S. Bank in such other capacities without any further action by U.S. Bank in such other capacities. 

Subject to certain exceptions, the provisions of the Purchase Contract and Pledge Agreement may be amended with the consent of the Holders of a majority of
the Purchase Contracts. 
 The Purchase Contracts shall be governed by, and construed in accordance with, the laws of the State of New York, without giving
effect to the conflicts of law provisions thereof to the extent a different law would govern as a result. 
 The Purchase Contracts shall not, prior to the
settlement thereof, entitle the Holder to any of the rights of a holder of shares of Common Stock. 
 Prior to due presentment of this Certificate for
registration of transfer, the Company, the Purchase Contract Agent and any agent of the Company or the Purchase Contract Agent may treat the Person in whose name this Corporate Units Certificate is registered as the owner of the Corporate Units
evidenced hereby for the purpose of receiving payments of Contract Adjustment Payments (subject to any applicable record date), performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any payments in respect
thereof be overdue and notwithstanding any notice to the contrary, and neither the Company, the Purchase Contract Agent nor any such agent shall be affected by notice to the contrary.

Series A Treasury Units 
 This Treasury Units
Certificate certifies that [______] is the registered Holder of the number of Treasury Units set forth above [For inclusion in Global Certificates only—or such other number of Treasury Units reflected in the Schedule of Increases or Decreases
in Global Certificate attached hereto], which number, taken together with the number of all other Outstanding Treasury Units and the number of all Outstanding Corporate Units and Outstanding Cash Settled Units, shall not exceed 8,625,000. Each
Treasury Unit consists of (i) an undivided beneficial ownership interest in a Treasury Security, subject to the Pledge of such Treasury Security by such Holder pursuant to the Purchase Contract and Pledge Agreement, and (ii) the rights and
obligations of the Holder under one Purchase Contract with the Company. 
 All capitalized terms used herein without definition herein and that are defined
in the Purchase Contract and Pledge Agreement (as defined on the reverse hereof) have the meaning set forth therein. 
 In the event of any inconsistency
between the provisions of this Treasury Units Certificate and the provisions of the Purchase Contract and Pledge Agreement, the provisions of the Purchase Contract and Pledge Agreement shall govern and control. 

Pursuant to the Purchase Contract and Pledge Agreement, the Treasury Security underlying each Treasury Unit evidenced hereby has been pledged to the
Collateral Agent, for the benefit of the Company, to secure the obligations of the Holder under the Purchase Contract comprising part of such Treasury Unit. 

The Company shall pay, on each Contract Adjustment Payment Date, in respect of each Purchase Contract forming part of a Treasury Unit evidenced hereby, an
amount (the “Contract Adjustment Payments”) equal to 7.75% per year of the Stated Amount for the period from and including the immediately preceding Contract Adjustment Payment Date on which Contract Adjustment Payments were paid
(or if none, April 19, 2021) to but excluding such Contract Adjustment Payment Date. Such Contract Adjustment Payments shall be payable in cash, shares of Common Stock or a combination thereof, at the Company’s election, to the Person in
whose name this Treasury Units Certificate is registered at the close of business on the Record Date for such Contract Adjustment Payment Date. The Company may, at its option, defer such Contract Adjustment Payments as described in the Purchase
Contract and Pledge Agreement. The Contract Adjustment Payments are unsecured and will rank subordinate and junior in right of payment to all of the Company’s existing and future Indebtedness. 

Each Purchase Contract evidenced hereby obligates the Holder of this Treasury Units Certificate to purchase, and the Company to sell, on the Purchase Contract
Settlement Date at a Purchase Price equal to the Stated Amount, a number of newly issued shares of Common Stock of the Company, equal to the Settlement Rate, unless on or prior to the Purchase Contract Settlement Date there shall have occurred a
Termination Event, an Early Settlement or a Fundamental 

  
 B-2 

 
Change Early Settlement with respect to such Purchase Contract, all as provided in the Purchase Contract and Pledge Agreement. The Purchase Price for the shares of Common Stock purchased pursuant
to each Purchase Contract evidenced hereby, if not paid earlier, shall be paid on the Purchase Contract Settlement Date by application of the proceeds from the Treasury Security pledged to secure the obligations under such Purchase Contract of the
Holder of the Treasury Units of which such Purchase Contract is a part. 
 Contract Adjustment Payments paid in cash will be payable at the office of the
Purchase Contract Agent in New York City, except that Contract Adjustment Payments with respect to Global Certificates will be made by wire transfer of immediately available funds to the Depositary. If the book-entry system for the Treasury Units
has been terminated, the Contract Adjustment Payments paid in cash will be payable, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or
by wire transfer to the account designated by such Person by prior written notice to the Purchase Contract Agent, given at least ten calendar days prior to the Contract Adjustment Payment Date. 

Each Purchase Contract evidenced hereby obligates the Holder and the Beneficial Owner to agree, for United States federal income tax purposes, to
(i) treat the Beneficial Owner’s acquisition of the Treasury Units as an acquisition of the Treasury Security and Purchase Contracts constituting the Treasury Units and (ii) treat the Beneficial Owner as the owner of the applicable
Treasury Security. 
 Reference is hereby made to the further provisions set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the Purchase Contract Agent by
manual or electronic signature, this Treasury Units Certificate shall not be entitled to any benefit under the Purchase Contract and Pledge Agreement or be valid or obligatory for any purpose.

 (REVERSE OF TREASURY UNITS CERTIFICATE) 

Each Purchase Contract evidenced hereby is governed by a Purchase Contract and Pledge Agreement, dated as of April 19, 2021 (as may be supplemented from
time to time, the “Purchase Contract and Pledge Agreement”), between the Company and U.S. Bank National Association, as Purchase Contract Agent (in such capacity, including its successors thereunder, the “Purchase Contract
Agent”), and as Collateral Agent, Custodial Agent and Securities Intermediary (in such capacities, including its successors thereunder, the “Collateral Agent”), to which Purchase Contract and Pledge Agreement and
supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Purchase Contract Agent, the Collateral Agent, the Company and the
Holders and of the terms upon which the Treasury Units Certificates are, and are to be, executed and delivered. 
 Each Purchase Contract evidenced hereby
obligates the Holder of this Treasury Units Certificate to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount, a number of newly issued shares of Common Stock equal to the Settlement
Rate, unless an Early Settlement, a Fundamental Change Early Settlement or a Termination Event with respect to the Units of which such Purchase Contract is a part shall have occurred. 

No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in Section 5.07 of the
Purchase Contract and Pledge Agreement. 
 Each Purchase Contract evidenced hereby that is settled through Early Settlement or Fundamental Change Early
Settlement shall obligate the Holder of the related Treasury Units to purchase at the Purchase Price and the Company to sell, a number of newly issued shares of Common Stock determined pursuant to the Purchase Contract and Pledge Agreement. 

In accordance with the terms of the Purchase Contract and Pledge Agreement, unless a Termination Event shall have occurred, the Holder of this Treasury Units
Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby by effecting an Early Settlement or, if applicable, a Fundamental Change Early Settlement of each such Purchase
Contract or by applying the proceeds of the Treasury Security underlying such Holder’s Treasury Unit equal to the Purchase Price for such Purchase Contract to the purchase of the Common Stock. 

The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder
unless it shall have received payment of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder in the manner set forth in the Purchase Contract and Pledge Agreement. 

Each Purchase Contract evidenced hereby and all obligations and rights of the Company and the Holder thereunder, including, without limitation, the rights of
the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments, shall terminate if a Termination Event shall occur. Upon the occurrence of a Termination Event, the Company shall give written notice to the Purchase
Contract Agent and to the Holders, at their addresses as they 

  
 B-6 

 
appear in the Security Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Treasury Security underlying each Treasury Unit from the Pledge. A
Treasury Unit shall thereafter represent the right to receive the Treasury Security underlying such Treasury Unit, in accordance with the terms of the Purchase Contract and Pledge Agreement. 

The Treasury Units Certificates are issuable only in registered form and only in denominations of a single Treasury Unit and any integral multiple thereof.
The transfer of any Treasury Units Certificate will be registered and Treasury Units Certificates may be exchanged as provided in the Purchase Contract and Pledge Agreement. A Holder who elects to substitute Mandatory Convertible Preferred Stock for
the Treasury Security, thereby recreating Corporate Units, shall be responsible for any taxes, governmental charges or other fees or expenses payable in connection therewith. Except as provided in the Purchase Contract and Pledge Agreement, such
Treasury Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Treasury Unit in respect of the Treasury Security and the Purchase Contract constituting such Treasury Unit may be transferred and
exchanged only as a Treasury Unit. 
 Subject to, and in compliance with, the conditions and terms set forth in the Purchase Contract and Pledge Agreement,
the Holder of Treasury Units may effect a Collateral Substitution. From and after such Collateral Substitution, each Unit for which Pledged Convertible Preferred Shares secure the Holder’s obligations under the Purchase Contract shall be
referred to as a “Corporate Unit”. A Holder may make such Collateral Substitution only in integral multiples of 10 Treasury Units for 10 Corporate Units. 

Subject to and upon compliance with the provisions of, and certain exceptions described in, the Purchase Contract and Pledge Agreement, at the option of the
Holder thereof, Purchase Contracts underlying Units may be settled early by effecting an Early Settlement or a Fundamental Change Early Settlement as provided in the Purchase Contract and Pledge Agreement. 

Upon registration of transfer of this Treasury Units Certificate, the transferee shall be bound (without the necessity of any other action on the part of such
transferee, except as may be required by the Purchase Contract Agent pursuant to the Purchase Contract and Pledge Agreement), under the terms of the Purchase Contract and Pledge Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contracts evidenced by this Treasury Units Certificate. The Company covenants and agrees, and the Holder, by its acceptance hereof, likewise covenants and agrees, to be bound by
the provisions of this paragraph. 
 The Holder of this Treasury Units Certificate, by its acceptance hereof, irrevocably appoints the Purchase Contract
Agent to enter into and perform the related Purchase Contracts forming part of the Treasury Units evidenced hereby, the Purchase Contract and Pledge Agreement and the Remarketing Agreement identified therein, as the same may be amended, amended and
restated, supplemented or otherwise modified or replaced from time to time (the “Remarketing Agreement”), on its behalf and in its name as its
attorney-in-fact, and the Holder of this Treasury Units Certificate hereby authorizes the Purchase Contract Agent to take such actions on its behalf and to exercise such
powers as are delegated to the Purchase Contract Agent by the 

  
 B-7 

 
terms of the Purchase Contract and Pledge Agreement, the Remarketing Agreement, or under any other document or instrument referred to or provided for herein or in connection herewith; expressly
withholds any consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code, agrees to be bound by the terms and provisions
thereof and the Treasury Units evidenced hereby (including, but not limited to, the terms and provisions of the Purchase Contract and Pledge Agreement) for so long as it remains of a Holder of such Unit, covenants and agrees to perform its
obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract and Pledge Agreement, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract and Pledge Agreement on its behalf as its attorney-in-fact, and consents to the Pledge of the Treasury Security underlying this Treasury Units Certificate pursuant to the Purchase Contract and Pledge Agreement. The
Holder further covenants and agrees, that, to the extent and in the manner provided in the Purchase Contract and Pledge Agreement, but subject to the terms thereof, payments in respect of the Treasury Security on the Purchase Contract Settlement
Date equal to the aggregate Purchase Price for the related Purchase Contracts shall be paid by the Collateral Agent to the Company in satisfaction of such Holder’s obligations under the related Purchase Contracts and such Holder shall acquire
no right, title or interest in such payments. The Holder of this Treasury Units Certificate hereby accepts the authorizations, appointments, acknowledgments and other actions taken by the Purchase Contract Agent in accordance with the Purchase
Contract and Pledge Agreement, the Remarketing Agreement or any other document or instrument referred to or provided for or in connection with the Purchase Contract and Pledge Agreement. Upon U.S. Bank’s receipt of any initial direction, notice
or instruction hereunder, any further instruction, notice or direction that U.S. Bank is required to make to U.S. Bank in its other capacities under the terms of this Agreement shall be deemed by the Holder of this Treasury Units Certificate as
being made by U.S. Bank in such other capacities without any further action by U.S. Bank in such other capacities. 
 Subject to certain exceptions, the
provisions of the Purchase Contract and Pledge Agreement may be amended with the consent of the Holders of a majority of the Purchase Contracts. 
 The
Purchase Contracts shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to the conflicts of law provisions thereof to the extent a different law would govern as a result. 

The Purchase Contracts shall not, prior to the settlement thereof, entitle the Holder to any of the rights of a holder of shares of Common Stock. 

Prior to due presentment of this Certificate for registration of transfer, the Company, the Purchase Contract Agent and any agent of the Company or the
Purchase Contract Agent may treat the Person in whose name this Treasury Units Certificate is registered as the owner of the Treasury Units evidenced hereby for the purpose of receiving payments of Contract Adjustment Payments (subject to any
applicable record date), performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any payments in respect thereof be overdue and notwithstanding any notice to the contrary, and neither the Company, the Purchase
Contract Agent nor any such agent shall be affected by notice to the contrary.

Series A Cash Settled Units 
 This Cash Settled
Units Certificate certifies that [_____] is the registered Holder of the number of Cash Settled Units set forth above [For inclusion in Global Certificates only—or such other number of Cash Settled Units reflected in the Schedule of Increases
or Decreases in Global Certificate attached hereto], which number, taken together with the number of all other Outstanding Cash Settled Units and the number of all Outstanding Corporate Units and Outstanding Treasury Units, shall not exceed
8,625,000. Each Cash Settled Unit consists of (i) $100 in Cash, subject to the Pledge thereof by such Holder pursuant to the Purchase Contract and Pledge Agreement, and (ii) the rights and obligations of the Holder under one Purchase Contract
with the Company. 
 All capitalized terms used herein without definition herein and that are defined in the Purchase Contract and Pledge Agreement (as
defined on the reverse hereof) have the meaning set forth therein. 
 Pursuant to the Purchase Contract and Pledge Agreement, the Cash underlying each Cash
Settled Unit evidenced hereby has been pledged to the Collateral Agent, for the benefit of the Company, to secure the obligations of the Holder under the Purchase Contract comprising part of such Cash Settled Unit. 

The Company shall pay, on each Contract Adjustment Payment Date, in respect of each Purchase Contract forming part of a Cash Settled Unit evidenced hereby, an
amount (the “Contract Adjustment Payments”) equal to 7.75% per year of the Stated Amount for the period from and including the immediately preceding Contract Adjustment Payment Date on which Contract Adjustment Payments were paid
(or if none, April 19, 2021) to but excluding such Contract Adjustment Payment Date. Such Contract Adjustment Payments shall be payable in cash, shares of Common Stock or a combination thereof, at the Company’s election, to the Person in
whose name this Cash Settled Units Certificate is registered at the close of business on the Record Date for such Contract Adjustment Payment Date. The Company may, at its option, defer such Contract Adjustment Payments as described in the Purchase
Contract and Pledge Agreement. The Contract Adjustment Payments are unsecured and will rank subordinate and junior in right of payment to all of the Company’s existing and future Indebtedness. 

Each Purchase Contract evidenced hereby obligates the Holder of this Cash Settled Units Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a Purchase Price equal to the Stated Amount, a number of newly issued shares of Common Stock of the Company, equal to the Settlement Rate, unless on or prior to the Purchase Contract Settlement Date there shall have
occurred a Termination Event, an Early Settlement or a Fundamental Change Early Settlement with respect to such Purchase Contract, all as provided in the Purchase Contract and Pledge Agreement. The Purchase Price for the shares of Common Stock
purchased pursuant to each Purchase Contract evidenced hereby shall be paid on the Purchase Contract Settlement Date by application of the Cash pledged to secure the obligations under such Purchase Contract of the Holder of the Cash Settled Units of
which such Purchase Contract is a part. 

  
 C-2 

 Contract Adjustment Payments paid in cash will be payable at the office of the Purchase Contract Agent in
New York City, except that Contract Adjustment Payments with respect to Global Certificates will be made by wire transfer of immediately available funds to the Depositary. If the book-entry system for the Cash Settled Units has been terminated, the
Contract Adjustment Payments paid in cash will be payable, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or by wire transfer to the
account designated by such Person by prior written notice to the Purchase Contract Agent, given at least ten calendar days prior to the Contract Adjustment Payment Date. 

Each Purchase Contract evidenced hereby obligates the Holder and the Beneficial Owner to agree, for United States federal income tax purposes, to
(i) treat the Beneficial Owner’s acquisition of the Cash Settled Units as an acquisition of the Cash and Purchase Contracts constituting the Cash Settled Units and (ii) treat the Beneficial Owner as the owner of the Cash. 

Reference is hereby made to the further provisions set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if
set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the Purchase Contract Agent by manual or electronic
signature, this Cash Settled Units Certificate shall not be entitled to any benefit under the Purchase Contract and Pledge Agreement or be valid or obligatory for any purpose.

 (REVERSE OF CASH SETTLED UNITS CERTIFICATE) 

Each Purchase Contract evidenced hereby is governed by a Purchase Contract and Pledge Agreement, dated as of April 19, 2021 (as may be supplemented from
time to time, the “Purchase Contract and Pledge Agreement”), between the Company and U.S. Bank National Association, as Purchase Contract Agent (in such capacity, including its successors thereunder, the “Purchase Contract
Agent”), and as Collateral Agent, Custodial Agent and Securities Intermediary (in such capacities, including its successors thereunder, the “Collateral Agent”), to which Purchase Contract and Pledge Agreement and
supplemental agreements thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Purchase Contract Agent, the Collateral Agent, the Company and the
Holders and of the terms upon which the Cash Settled Units Certificates are, and are to be, executed and delivered. 
 Each Purchase Contract evidenced
hereby obligates the Holder of this Cash Settled Units Certificate to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount, a number of newly issued shares of Common Stock equal to the
Settlement Rate, unless an Early Settlement, a Fundamental Change Early Settlement or a Termination Event with respect to the Unit of which such Purchase Contract is a part shall have occurred. 

No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as provided in Section 5.07 of the
Purchase Contract and Pledge Agreement. 
 Each Purchase Contract evidenced hereby that is settled through Fundamental Change Early Settlement shall
obligate the Holder of the related Cash Settled Units to purchase at the Purchase Price and the Company to sell, a number of newly issued shares of Common Stock determined pursuant to the Purchase Contract and Pledge Agreement. 

In accordance with the terms of the Purchase Contract and Pledge Agreement, unless a Termination Event shall have occurred, the Holder of this Cash Settled
Units Certificate shall pay the Purchase Price for the shares of Common Stock to be purchased pursuant to each Purchase Contract evidenced hereby by effecting, if applicable, a Fundamental Change Early Settlement of each such Purchase Contract or by
applying the Cash underlying such Holder’s Cash Settled Unit equal to the Purchase Price for such Purchase Contract to the purchase of the Common Stock. 

The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder
unless it shall have received payment of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder in the manner set forth in the Purchase Contract and Pledge Agreement. 

Each Purchase Contract evidenced hereby and all obligations and rights of the Company and the Holder thereunder, including, without limitation, the rights of
the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments, shall terminate if a Termination Event shall occur. Upon the occurrence of a Termination Event, the Company shall give written notice to the Purchase
Contract Agent and the Holders, at their addresses as they appear in the Security Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Cash underlying each Cash Settled Unit from the Pledge. A Cash
Settled Unit shall thereafter represent the right to receive the Cash underlying such Cash Settled Unit, in accordance with the terms of the Purchase Contract and Pledge Agreement. 

  
 C-6 

 The Cash Settled Units Certificates are issuable only in registered form and only in denominations of a
single Cash Settled Unit and any integral multiple thereof. The transfer of any Cash Settled Units Certificate will be registered and Cash Settled Units Certificates may be exchanged as provided in the Purchase Contract and Pledge Agreement. A
Holder who elects to substitute Mandatory Convertible Preferred Stock for the Cash, thereby recreating Corporate Units, shall be responsible for any taxes, governmental charges or other fees or expenses payable in connection therewith. Except as
provided in the Purchase Contract and Pledge Agreement, a Cash Settled Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Cash Settled Unit in respect of the Cash and the Purchase Contract
constituting such Cash Settled Unit may be transferred and exchanged only as a Cash Settled Unit. 
 Subject to, and in compliance with, the conditions and
terms set forth in the Purchase Contract and Pledge Agreement, the Holder of Cash Settled Units may effect a Collateral Substitution. From and after such Collateral Substitution, each Unit for which Pledged Convertible Preferred Shares secure the
Holder’s obligations under the Purchase Contract shall be referred to as a “Corporate Unit”. A Holder may make such Collateral Substitution only in integral multiples of 10 Cash Settled Units for 10 Corporate Units. 

Subject to and upon compliance with the provisions of, and certain exceptions described in, the Purchase Contract and Pledge Agreement, at the option of the
Holder thereof, Purchase Contracts underlying Units may be settled early by effecting a Fundamental Change Early Settlement as provided in the Purchase Contract and Pledge Agreement. 

Upon registration of transfer of this Cash Settled Units Certificate, the transferee shall be bound (without the necessity of any other action on the part of
such transferee, except as may be required by the Purchase Contract Agent pursuant to the Purchase Contract and Pledge Agreement), under the terms of the Purchase Contract and Pledge Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contracts evidenced by this Cash Settled Units Certificate. The Company covenants and agrees, and the Holder, by its acceptance hereof, likewise covenants and agrees, to be bound
by the provisions of this paragraph. 
 The Holder of this Cash Settled Units Certificate, by its acceptance hereof, irrevocably appoints the Purchase
Contract Agent to enter into and perform the related Purchase Contracts forming part of the Cash Settled Units evidenced hereby, the Purchase Contract and Pledge Agreement and the Remarketing Agreement identified therein, as the same may be amended,
amended and restated, supplemented or otherwise modified or replaced from time to time (the “Remarketing Agreement”), on its behalf and in its name as its
attorney-in-fact, and the Holder of this Cash Settled Units Certificate hereby authorizes the Purchase Contract Agent to take such actions on its behalf and to exercise
such powers as are delegated to the Purchase Contract Agent by the terms of the Purchase Contract and Pledge Agreement, the Remarketing Agreement, or under 

  
 C-7 

 
any other document or instrument referred to or provided for herein or in connection herewith; expressly withholds any consent to the assumption (i.e., affirmance) of the Purchase Contracts by
the Company or its trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code, agrees to be bound by the terms and provisions thereof and the Cash Settled Units evidenced hereby (including, but not limited to, the
terms and provisions of the Purchase Contract Agreement) for so long as it remains of a Holder of such Unit, covenants and agrees to perform its obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract and
Pledge Agreement, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract and Pledge Agreement on its behalf as its attorney-in-fact, and
consents to the Pledge of the Cash underlying this Cash Settled Units Certificate pursuant to the Purchase Contract and Pledge Agreement. The Holder further covenants and agrees, that, to the extent and in the manner provided in the Purchase
Contract and Pledge Agreement, but subject to the terms thereof, on the Purchase Contract Settlement Date an amount of Pledged Cash equal to the aggregate Purchase Price for the related Purchase Contracts shall be paid by the Collateral Agent to the
Company in satisfaction of such Holder’s obligations under such Purchase Contracts. The Holder of this Cash Settled Units Certificate hereby accepts the authorizations, appointments, acknowledgments and other actions taken by the Purchase
Contract Agent in accordance with the Purchase Contract and Pledge Agreement, the Remarketing Agreement or any other document or instrument referred to or provided for or in connection with the Purchase Contract and Pledge Agreement. Upon U.S.
Bank’s receipt of any initial direction, notice or instruction hereunder, any further instruction, notice or direction that U.S. Bank is required to make to U.S. Bank in its other capacities under the terms of this Agreement shall be deemed by
the Holder of this Cash Settled Units Certificate as being made by U.S. Bank in such other capacities without any further action by U.S. Bank in such other capacities. 

Subject to certain exceptions, the provisions of the Purchase Contract and Pledge Agreement may be amended with the consent of the Holders of a majority of
the Purchase Contracts. 
 The Purchase Contracts shall be governed by, and construed in accordance with, the laws of the State of New York, without giving
effect to the conflicts of law provisions thereof to the extent a different law would govern as a result. 
 The Purchase Contracts shall not, prior to the
settlement thereof, entitle the Holder to any of the rights of a holder of shares of Common Stock. 
 Prior to due presentment of this Certificate for
registration of transfer, the Company, the Purchase Contract Agent and any agent of the Company or the Purchase Contract Agent may treat the Person in whose name this Cash Settled Units Certificate is registered as the owner of the Cash Settled
Units evidenced hereby for the purpose of receiving payments of Contract Adjustment Payments (subject to any applicable record date), performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any payments in respect
thereof be overdue and notwithstanding any notice to the contrary, and neither the Company, the Purchase Contract Agent nor any such agent shall be affected by notice to the contrary. 

A copy of the Purchase Contract and Pledge Agreement is available for inspection at the Corporate Trust Office of the Purchase Contract Agent during regular
business hours.
