Holders, shall be entitled to take the relevant action with respect to the Corporate Units or the Treasury 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, 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.

manner, and (b) such originally executed instructions or directions shall be signed by an authorized representative of the party providing such instructions or directions. 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. The party providing electronic instructions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Agent, including without limitation the risk of the Agent acting on

Security Register, 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 any other provision of this Agreement or any Global Certificate, where this Agreement or any Global Certificate provides for
notice of any event (including any notice of redemption or repurchase) to a Holder of a Global Certificate (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depository (or its designee) pursuant to the standing
instructions from the Depository or its designee, including by electronic mail in accordance with Applicable Procedures.

Contract Agent, on behalf of the Holders of Corporate Units, has, on the date hereof, delivered to the Securities Intermediary the Notes underlying the Applicable Ownership Interests in Notes by delivering such Notes indorsed in blank. 

Upon the formation of a Treasury Unit pursuant to Section 3.13, 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 1/20th or 5% undivided beneficial ownership interest in a Treasury Security with a principal amount at maturity equal to $1,000,
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, such Holder’s interest in the Treasury Security forming
a part of such Treasury Unit to the Collateral Agent, 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 Obligations of the Holder under each Purchase Contract to purchase shares of Common Stock. 
 Prior to the purchase and
delivery of shares of Common Stock under each Purchase Contract, such Purchase Contract shall not 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 3.13 and Section 3.14 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 of such Certificates, and the Purchase Contract Agent in accordance with such Issuer Order shall authenticate, execute on behalf of
the Holders and deliver such Certificates. 
 The Certificates shall be executed on behalf of the Company by an Authorized Officer of the
Company. The signature of any such Authorized Officer on the Certificates may be manual or facsimile. 
 Certificates bearing the manual 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 facsimile 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. 

  
 28 

 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 signatory of the Purchase Contract Agent by manual 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 authenticate, execute on behalf of the Holders, and deliver,
in lieu of such definitive Certificates, temporary Certificates which are in substantially the form set forth in Exhibit A or Exhibit B 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 or Treasury 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 authenticate, execute on behalf of the Holder, 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 it may prescribe, 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 and Treasury 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, and the Purchase Contract Agent shall 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, of like tenor, and evidencing a like number of Corporate Units or Treasury Units, as the case may be. 

  
 29 

 At the option of the Holder, Certificates may be exchanged for other Certificates, of any
authorized denominations and evidencing a like number of Corporate Units or Treasury 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 authenticate, execute on behalf of the Holder, and deliver to the Holder the Certificates which the Holder making the exchange is
entitled to receive. 
 All Certificates issued upon any registration of transfer or exchange of a Certificate shall evidence the ownership
of the same number of Corporate Units or Treasury 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 or Treasury 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, other than any exchanges not involving any transfer to a person other than the Holder. 
 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 and deliver any Certificate in exchange for any other
Certificate presented or surrendered for registration of transfer or for exchange on or after any Early Settlement Date or any date on which the Fundamental Change Early Settlement Right is exercised with respect to such Certificate, any Termination
Date or the Business Day immediately preceding the Purchase Contract Settlement 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: 
 (i) if the Purchase Contract Settlement Date or
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 

  
 30 

 (ii) if a Termination Event, Early Settlement, or Fundamental Change Early
Settlement shall have occurred prior to the Purchase Contract Settlement Date, or a Cash Settlement shall have occurred, transfer the Notes, the Treasury Securities, or the Applicable Ownership Interests in the Treasury Portfolio, as the case may
be, underlying such Certificate, in each case subject to the applicable conditions and in accordance with the applicable provisions of Section 3.15 and Article 5. 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 initially issued in the form of one or more fully registered Global Certificates, to be delivered to the Depository or its custodian by, or on behalf of, the Company. The Company hereby designates DTC as the
initial Depository. The Company has entered into a letter of representations with DTC in the form provided by DTC and the Purchase Contract Agent in each of its capacities is hereby authorized to act in accordance with such letter and Applicable
Procedures. Such Global Certificates shall initially be registered on the Security Register in the name of Cede & Co., the nominee of the Depository, and no Beneficial Owner will receive a definitive Certificate representing such Beneficial
Owner’s interest in such Global Certificate, except as provided in Section 3.09. The Purchase Contract Agent shall enter into an agreement with the Depository 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 3.09: 

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

(ii) the Company shall be entitled to deal with the Depository for all purposes of this Agreement (including, without
limitation, making Contract Adjustment Payments 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 Depository 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 3.09; 
 (iii) 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 

(iv) except as set forth in the proviso of clause (ii) of this Section 3.06, the rights of the Beneficial Owners
shall be exercised only through the Depository and shall be limited to those established by law and agreements between such Beneficial Owners and the Depository or the Depository Participants. 

The Depository will make book-entry transfers among Depository Participants and receive and transmit Contract Adjustment Payments to such
Depository Participants. Transfers of securities evidenced by Global Certificates shall be made through the facilities of the Depository, and any cancellation of, or increase or decrease in the number of, such securities (including the creation of
Treasury Units and the recreation of Corporate Units pursuant to Section 3.13 and Section 3.14 respectively) shall be accomplished by making appropriate annotations on the Schedule of Increases and Decreases set forth in such Global
Certificate. 

  
 31 

 Section 3.07. Notices to Holders. Whenever a notice or other communication to
the Holders is required to be given under this Agreement, the Company or the Company’s agent shall give such notices and communications to the Holders and, with respect to any Units registered in the name of the Depository or the nominee of the
Depository, the Company or the Company’s agent shall, except as set forth herein, have no obligations to the Beneficial Owners. 

Section 3.08. Appointment of Successor Depository. If the Depository elects to discontinue its services as securities depository
with respect to the Units, the Company may, in its sole discretion, appoint a successor Depository with respect to the Units, as long as such successor Depository constitutes a “clearing agency” registered under Section 17A of the
Exchange Act. 
 Section 3.09. Definitive Certificates. 

If: 
 (i) the
Depository notifies the Company that it is unwilling or unable to continue its services as securities depository with respect to the Units and no successor Depository has been appointed pursuant to Section 3.08 within 90 days after the
Company’s receipt of such notice; 
 (ii) the Depository ceases to be a “clearing agency” registered under
Section 17A of the Exchange Act when the Depository is required to be so registered to act as the Depository and the Company receives notice of such cessation, and no successor Depository has been appointed pursuant to Section 3.08 within
90 days after the Company’s receipt of such notice or the Company’s becoming aware of such cessation; or 
 (iii)
any Event of Default with respect to the Notes, or any event that after notice or lapse of time would constitute an Event of Default with respect to the Notes, has occurred and is continuing, or the Company has failed to perform any of its
obligations under this Agreement, the Units or the Purchase Contracts, and any Beneficial Owner requests that its beneficial interest be exchanged for a definitive Certificate; 

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 Depository, accompanied by registration instructions, the Company shall cause definitive Certificates to be
delivered to Beneficial Owners in accordance with instructions provided by the Depository; provided that in the case of clause (iii) only the beneficial interests of the Beneficial Owners so requesting shall be exchanged for definitive
Certificates, and the aggregate number of Units represented by the Global Certificate will be reduced accordingly, in accordance with Applicable Procedures and standing arrangements between the Purchase Contract Agent and the Depository. 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. 

  
 32 

 Section 3.10. Mutilated, Destroyed, Lost and Stolen Certificates. If any
mutilated Certificate is surrendered to the Purchase Contract Agent or its agent at the Corporate Trust Office, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on
behalf of the Holder, and deliver to the Holder in exchange therefor, a new Certificate, evidencing the same number of Corporate Units or Treasury Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding. 

If there shall be delivered to the Company and the Purchase Contract Agent (i) evidence to their satisfaction of the destruction, loss or
theft of any Certificate, and (ii) such indemnity as may be required by them to hold each of them and any agent of any of them harmless, 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 authenticate, execute on behalf of the Holder, 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 or Treasury 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, 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 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: 
 (i) if the Purchase Contract Settlement Date with
respect to such lost, stolen, destroyed or mutilated Certificate has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Units evidenced by such Certificate; and 

(ii) if a Termination Event with respect to such mutilated, destroyed, lost or stolen Certificate shall have occurred prior to
the Purchase Contract Settlement Date, transfer the Notes, the Treasury Securities or the Applicable Ownership Interests in the Treasury Portfolio, as the case may be, underlying such Certificate, subject to the applicable conditions and in
accordance with the applicable provisions of Section 3.15 and Article 5. 
 Upon the issuance of any new Certificate under this
Section, 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 (including, without
limitation, the fees and expenses of the Purchase Contract Agent) connected therewith. 

  
 33 

 Every new Certificate issued pursuant to this Section 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. 

The provisions of this Section 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 3.11. Persons Deemed Owners. Prior to
due presentment of a Certificate for registration of transfer, the Company and the Purchase Contract Agent, and any agent of the Company or the Purchase Contract Agent, may treat the Person in whose name such Certificate is registered as the owner
of the Units evidenced thereby for purposes of (subject to any applicable record date) any payment or distribution with respect to the Notes underlying the Applicable Ownership Interests in Notes, on the Applicable Ownership Interests in the
Treasury Portfolio (as specified in clause (A)(ii) and (B)(ii) of the definition of Applicable Ownership Interests in the Treasury Portfolio) or payment of Contract Adjustment Payments and performance of the Purchase Contracts and for all other
purposes whatsoever in connection with such Units (subject to the proviso contained in clause (ii) of Section 3.06), 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 notice to the contrary. 

None of the Purchase Contract Agent or the Securities Registrar shall have any responsibility or obligation to any Beneficial Owner in Units
represented by a Global Certificate or other Person with respect to the accuracy of the records of the Depository 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 Depository) 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 Depository or its nominee in the case of a Global Certificate). The rights of Beneficial Owners in the Units
underlying a Global Certificate shall be exercised only through the Depository subject to its Applicable Procedures. The Purchase Contract Agent and the Securities Registrar shall be entitled to rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its members, participants and any Beneficial Owners. The Purchase Contract Agent and the Securities Registrar shall be entitled to deal with the Depository, 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 making of any payment or delivery hereunder 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 contained in clause (ii) of Section 3.06). None of
the Purchase Contract Agent or the Securities Registrar shall have any responsibility or liability for any acts or omissions of the Depository with respect to any Units underlying such Global Certificate, for the records of the Depository, including

  
 34 

 
records in respect of beneficial ownership interests in respect of Units underlying such Global Certificate, for any transactions between the Depository and any agent member or between or among
the Depository, any such agent member and/or any Holder or Beneficial Owner in any Units underlying such Global Certificate, or for any transfers of beneficial interests in any Units underlying such Global Certificate. 

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 Depository (or its nominee), as a Holder, with respect to such Global
Certificate, or impair, as between such Depository and the related Beneficial Owner, the operation of customary practices governing the exercise of rights of the Depository (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 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 3.12.
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
Notes underlying the Applicable Ownership Interests in Notes, the Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, after the occurrence of a Termination Event or pursuant to a Cash Settlement, 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 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 3.12, except as expressly permitted by this Agreement. All cancelled
Certificates held by the Purchase Contract Agent shall be disposed of in accordance with its customary practices. 
 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 3.13. Creation of Treasury Units by Substitution of Treasury Securities. (a) Subject to the conditions set forth in
this Agreement, a Holder of Corporate Units may, at any time from and after the date of this Agreement, other than during a Blackout Period or after a Successful Remarketing or a Special Event Redemption, effect a Collateral Substitution and
separate the Notes underlying the Pledged Applicable Ownership Interests in Notes in respect of such Holder’s Corporate Units by substituting for such Pledged Applicable Ownership Interests in Notes for which Collateral Substitution is being
made, Treasury Securities in an aggregate 

  
 35 

 
principal amount at maturity equal to the aggregate principal amount of the Notes underlying the Pledged Applicable Ownership Interests in Notes; provided that Holders may make Collateral
Substitutions only in integral multiples of 20 Corporate Units. To effect such substitution, the Holder must: 
 (1) Transfer
to the Collateral Agent, for credit to the Collateral Account, Treasury Securities or security entitlements with respect thereto having an aggregate principal amount at maturity equal to the aggregate principal amount of the Notes underlying the
Pledged Applicable Ownership Interests in Notes for which such Collateral Substitution is made; and 
 (2) 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 C hereto, whereupon the Purchase Contract Agent shall promptly provide an instruction to such effect
to the Collateral Agent, substantially in the form of Exhibit F hereto. 
 Upon confirmation that the Treasury Securities described in
clause (1) above or security entitlements with respect thereto have been credited to the Collateral Account and receipt of the instruction to the Collateral Agent described in clause (2) above, the Collateral Agent shall promptly release
such Pledged Applicable Ownership Interests in Notes from the Pledge by directing the Securities Intermediary by a notice, substantially in the form of Exhibit G hereto, to Transfer the Notes underlying such Pledged Applicable Ownership Interests in
Notes to the Purchase Contract Agent for distribution to such Holder, free and clear of the Pledge created hereby. 
 The substituted
Treasury Securities will be pledged to the Company through the Collateral Agent to secure such Holder’s obligation to purchase shares of Common Stock under the related Purchase Contract. 

Upon credit to the Collateral Account of Treasury Securities 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 Notes underlying the appropriate Pledged Applicable Ownership Interests in Notes to the Purchase Contract Agent for
distribution to such Holder, free and clear of the Pledge created hereby. 
 Upon receipt of the Notes underlying such Pledged Applicable
Ownership Interests in Notes, the Purchase Contract Agent shall promptly: 
 (i) cancel the related Corporate Units; 

(ii) Transfer the Notes to the Holder; and 

(iii) deliver Treasury Units in book-entry form, or if applicable, authenticate, execute on behalf of such Holder 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. 

  
 36 

 Holders who elect to separate the Notes by substituting Treasury Securities for Applicable
Ownership Interest in Notes shall be responsible for any taxes, governmental charges or other fees or expenses (including, without limitation, fees and expenses payable to the Collateral Agent) attributable to 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 this Section 3.13 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 with the Securities Intermediary, any distributions on the Notes underlying the Applicable Ownership Interests in
Notes 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 that may be required
by the Purchase Contract Agent and the Company. 
 (c) Except as provided for in this Section 3.13, or in connection with a Cash
Settlement, 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 Applicable Ownership Interests in Notes or Applicable Ownership Interests in the Treasury Portfolio, as the case may be, and the Purchase Contract comprising such Corporate Units may be
acquired, and may be transferred and exchanged, only as a Corporate Unit. 
 Section 3.14. Recreation of Corporate Units.
(a) Subject to the conditions set forth in this Agreement, a Holder of Treasury Units may effect a Collateral Substitution and recreate Corporate Units at any time from and after the date of this Agreement, other than during a Blackout Period
or after a Successful Remarketing or a Special Event Redemption; provided that Holders of Treasury Units may only recreate Corporate Units in integral multiples of 20 Treasury Units. To recreate Corporate Units, the Holder must: 

(1) Transfer to the Collateral Agent for credit to the Collateral Account Notes having an aggregate principal amount equal to
the aggregate principal amount at maturity of the Pledged Treasury Securities to be released; and 
 (2) Transfer the related
Treasury Units to the Purchase Contract Agent accompanied by a notice to the Purchase Contract Agent, substantially in the form of Exhibit C hereto, whereupon the Purchase Contract Agent shall promptly provide an instruction to such effect to the
Collateral Agent, substantially in the form of Exhibit H hereto. 
 Upon confirmation that the Notes described in clause (1) above have
been credited to the Collateral Account and receipt of the instruction from the Purchase Contract Agent described in clause (2) above, the Collateral Agent shall promptly release such Pledged Treasury Securities from the Pledge by directing the
Securities Intermediary by a notice, substantially in the form of Exhibit I hereto, to Transfer such Pledged Treasury Securities to the Purchase Contract Agent for distribution to such Holder, free and clear of the Pledge created hereby. 

  
 37 

 The substituted Notes will be pledged to the Company through the Collateral Agent to secure
such Holder’s obligation to purchase shares of Common Stock under the related Purchase Contract. 
 Upon credit to the Collateral
Account of Notes delivered by a Holder of Treasury Units and receipt of the related instruction from the Collateral Agent, the Securities Intermediary shall promptly Transfer the Pledged Treasury Securities to the Purchase Contract Agent for
distribution to such Holder, free and clear of the Pledge created hereby. 
 Upon receipt of such Treasury Securities, the Purchase Contract
Agent shall promptly: 
 (i) cancel the related Treasury Units; 

(ii) transfer the Treasury Securities to the Holder; and 

(iii) deliver Corporate Units in book-entry form or, if applicable, authenticate, execute on behalf of such Holder and deliver
Corporate Units in the form of a Corporate 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 Treasury Units. 

Holders who elect to recreate Corporate Units shall be responsible for any taxes, governmental charges or other fees or expenses (including,
without limitation, fees and expenses payable to the Collateral Agent), attributable to 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) Except as provided in this Section 3.14 or in connection with a Cash Settlement, 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 obligations of the Holder of
such Treasury Unit in respect of the interest in the Treasury Security and Purchase Contract composing such Treasury Unit may be acquired, and may be transferred and exchanged, only as a Treasury Unit. 

Section 3.15. Transfer of Collateral Upon Occurrence of Termination Event. (a) Upon receipt by the Collateral Agent of
written notice pursuant to Section 5.07 from the Company or the Purchase Contract Agent that a Termination Event has occurred, the Collateral Agent shall promptly release all Collateral from the Pledge and shall promptly instruct the Securities
Intermediary to Transfer: 
 (i) any Notes underlying Pledged Applicable Ownership Interests in Notes or security
entitlements with respect thereto or Applicable Ownership Interests in the Treasury Portfolio; 
 (ii) any Pledged Treasury
Securities; 

  
 38 

 (iii) any payments made by Holders (or the Permitted Investments, if any, of
such payments) pursuant to Section 5.02(b)(ix) or 5.03; and 
 (iv) any Proceeds and all other payments the Collateral
Agent receives in respect of the foregoing, 
 to the Purchase Contract Agent for the benefit of the Holders for distribution to such Holders, in accordance
with their respective interests, free and clear of the Pledge created hereby; provided, however, if any Holder or Beneficial Owner shall be entitled to receive Notes in an aggregate principal amount of less than $1,000, or greater than
$1,000 but not in an integral multiple of $1,000, the Purchase Contract Agent shall request, on behalf of such Holder or Beneficial Owner, that the Company issue, and promptly following such request the Company shall issue, Notes in denominations of
$50, or integral multiples thereof, in exchange for Notes in denominations of $1,000 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 its Pledged Treasury Securities, any securities having a principal amount at maturity of less than $1,000, the Purchase Contract Agent shall dispose of such Applicable Ownership Interests in the Treasury Portfolio or Pledged
Treasury Securities for cash and deliver to such Holder cash in lieu of delivering the Applicable Ownership Interests in the Treasury Portfolio or Pledged Treasury Securities, as the case may be. 

(b) Notwithstanding anything to the contrary in Section 3.15(a), if such Termination Event shall result from the Company 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 Notes underlying Pledged Applicable Ownership Interests in Notes, Applicable Ownership Interests in the
Treasury Portfolio, Pledged Treasury Securities and payments by Holders (or the Permitted Investments purchased with such payments) pursuant to Section 5.02 or 5.03 and Proceeds and all other payments received by the Collateral Agent in respect
of the foregoing, as the case may be, as provided by this Section 3.15, 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 this Section 3.15, and shall deliver or cause to be delivered such opinion 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 10 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 Notes underlying Pledged Applicable Ownership Interests in Notes, Applicable Ownership Interests in the Treasury Portfolio, Pledged Treasury Securities and the payments by Holders (or
the Permitted Investments, if any, of such payments) pursuant to Section 5.02 or 5.03 and Proceeds and all other payments received by the Collateral Agent in respect of the foregoing, as the case may be, as provided in this Section 3.15,
then the Purchase Contract Agent shall within 15 days after 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 Notes underlying Pledged Applicable Ownership Interests in Notes, Applicable Ownership Interests in the Treasury Portfolio, Pledged Treasury Securities and the payments by Holders
(or the Permitted Investments, if any, purchased with such payments) pursuant to Section 5.02 or 5.03 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 this
Section 3.15.

Agent of the Notes underlying Pledged Applicable Ownership Interests in Notes, the appropriate Applicable Ownership Interests in the Treasury Portfolio and/or the Pledged Treasury Securities, as the case may be, pursuant to this Section 3.15,
the Purchase Contract Agent shall request transfer instructions with respect to such Notes, Applicable Ownership Interests in the Treasury Portfolio and/or Pledged Treasury Securities, as the case may be, from each Holder by written request,

Units or Treasury Units, as the case may be, to such Holder by book-entry transfer, or other appropriate procedures, in accordance with such instructions and, in the case of the Notes underlying Pledged Applicable Ownership Interests in Notes, in

the Applicable Ownership Interests in the Treasury Portfolio or Pledged Treasury Securities, as the case may be, underlying such Corporate Units of Treasury 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 or Treasury Units or surrender of the Corporate Units Certificate or Treasury Units Certificate or the receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such
Corporate Units Certificate or Treasury Units Certificate has been destroyed, lost or stolen, together with any indemnity 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

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. 

Section 3.17. Substitutions. Whenever a Holder has the right to substitute Treasury Securities or Notes underlying Applicable
Ownership Interests in Notes, 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.

 (c) Each
Corporate Units Certificate evidencing Applicable Ownership Interests in Notes or Applicable Ownership Interests in the Treasury Portfolio delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of any other
Corporate Units Certificate shall carry the right to accrued and unpaid interest or distributions, and to accrued interest or distributions, which were carried by Applicable Ownership Interests in Notes or Applicable Ownership Interests in the

(3) Fundamental Change Early Settlement of the underlying Purchase Contract is properly effected pursuant to Section 5.05(b)(ii) or (4) a Collateral Substitution is properly effected pursuant to Section 3.13, in each case on a

Date shall be payable on such Payment Date notwithstanding such Cash Settlement, Early Settlement, Fundamental Change Early Settlement or Collateral Substitution, and such payment or distributions shall, subject to receipt thereof by the Purchase
Contract Agent, be payable to the Person in whose name the Corporate Units Certificate (or one or more Predecessor Corporate Units Certificates) was registered at the close of business on the Record Date. 

(e) Except as otherwise expressly provided in Section 4.01(d), in the case of any Corporate Unit with respect to which Cash Settlement,
Early Settlement or Fundamental Change Early Settlement of the underlying Purchase Contract is properly effected, or with respect to which a Collateral Substitution is properly effected, payments attributable to the Notes underlying Applicable
Ownership Interests in Notes or distributions on Applicable Ownership Interests in the Treasury Portfolio, as the case may be, that would otherwise be payable or made after the applicable Settlement Date or the date of the Collateral Substitution,
as the case may be, shall not be payable hereunder to the Holder of such Corporate Units; provided, however, that to the extent that such Holder continues to hold Separate Notes or Applicable Ownership Interests in the Treasury Portfolio that

(3) the Pledged Treasury Securities, shall be credited to the Collateral Account to be invested as directed in writing by the Company (if applicable) in Permitted Investments until the Purchase Contract Settlement Date, and such payments (or
the proceeds of such Permitted Investments, if applicable) shall be transferred to the Company on the Purchase Contract Settlement Date as provided in Sections 5.02 and 5.03 hereof to the extent necessary to satisfy the Holder’s obligation
pursuant to Section 5.01 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 distribution to
the applicable Holders for distribution to such Holders in accordance with their respective interests pursuant to Section 11.02, free and clear of the Pledge created hereby. If the Company fails to deliver investment instructions by 10:30 a.m.

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. 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. The Collateral Agent and the Securities Intermediary shall have no liability in respect of losses
incurred as a result of the failure of the Company to provide timely written investment direction. 

  
 42 

 (b) All payments received by the Securities Intermediary in respect of (1) the Notes,
(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 hereunder or that are otherwise not

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 Notes underlying Pledged Applicable Ownership Interests in Notes 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 Notes underlying Pledged Applicable Ownership Interests in Notes, including either notice of any meeting at which holders of the Notes are entitled to vote or the solicitation of
consents, waivers or proxies of holders of the Notes, 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, to execute and deliver to the Purchase Contract Agent such proxies and other instruments in respect of such Notes underlying Pledged Applicable Ownership Interests in Notes as are prepared
by the Company and delivered to the Purchase Contract Agent with respect to the Notes underlying Pledged Applicable Ownership Interests in Notes. 

(b) Upon receipt of notice of any meeting at which holders of Notes are entitled to vote or upon any solicitation of consents, waivers or
proxies of holders of Notes, the Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage prepaid, to the Holders of Corporate Units a notice: 

(i) containing such information as is contained in the notice or solicitation; 

(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 Notes entitled to vote) shall be entitled to instruct the Purchase Contract Agent as to the exercise of the voting rights pertaining to such Notes underlying
the Applicable Ownership Interests in Notes 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 received by the
Purchase Contract Agent at least six days prior to such meeting, the Purchase Contract Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum aggregate
principal amount of Notes (rounded down to the nearest integral multiple of $1,000) as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of Corporate Units, the Purchase Contract Agent
shall abstain from voting the Notes underlying Applicable Ownership Interests in Notes 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 as to the exercise of such voting rights in order to enable the Purchase Contract Agent to vote such Notes. 

  
 43 

 (c) The Holders of Corporate Units and the Holders of Treasury Units, in their capacity as
such Holders, shall have no voting or other rights in respect of the Common Stock. 
 Section 4.04. Payments and Deliveries 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 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 Intermediary shall use commercially reasonable efforts to deliver such payment to the Purchase Contract Agent no later than 10:00 a.m. (New York City time) on the next succeeding
Business Day. In connection with the Transfer of any Treasury 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 the
repayment of principal with respect to financial assets credited to the Collateral Account (other than, for the avoidance of doubt, interest on the Notes or distributions on the Applicable Ownership Interests in the Treasury Portfolio (as specified
in clause (A)(ii) or (B)(ii) of the definition thereof)) 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 Officers’ Certificate of the Company so directing, promptly deliver such payments to the Securities Intermediary for credit to the Collateral Account or, if the Obligations have become due and payable, 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. 

ARTICLE 5 
 THE PURCHASE
CONTRACTS 
 Section 5.01. Purchase of Shares of Common Stock. (a) Each Purchase Contract shall obligate the Holder of the
related Unit to purchase, and the Company to issue and deliver, on the Purchase Contract Settlement Date at a price equal to the Stated Amount (the “Purchase Price”), a number of shares of Common Stock equal to the Settlement Rate,
together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 5.09, unless an Early Settlement Date, 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, subject to Section 5.05(b)(ii). 
 The “Settlement Rate” is
determined as follows: 
 (i) If the Applicable Market Value is equal to or greater than the Threshold Appreciation Price,
the Settlement Rate will be 0.6354 shares of Common Stock (such Settlement Rate, subject to adjustment as provided in Section 5.05(a), being referred to as the “Minimum Settlement Rate”); 

  
 44 

 (ii) if the Applicable Market Value is less than the Threshold Appreciation
Price but greater than $64.24 (subject to adjustment, as set forth in Section 5.05(a)(vii)(1), the “Reference Price”), the Settlement Rate will be a number of shares of Common Stock equal to the Stated Amount, divided by
the Applicable Market Value, rounded to the nearest 1/10,000th of a share; and 
 (iii) if the Applicable Market Value is
less than or equal to the Reference Price, the Settlement Rate will be 0.7783 shares of Common Stock (such Settlement Rate, subject to adjustment as provided in Section 5.05(a), being referred to as the “Maximum Settlement
Rate”). 
 The Maximum Settlement Rate, Minimum Settlement Rate and the Applicable Market Value (as defined below) are subject to
adjustment as provided in Section 5.05 (and, in the case of each Fixed Settlement Rate, shall be rounded upward or downward to the nearest 1/10,000th of a share). 

The “Applicable Market Value” means, as determined by the Company, the average VWAP of the Common Stock on each Trading Day
during the Market Value Averaging Period, subject to Section 5.05(b)(i); provided that if 20 Trading Days for the Common Stock have not occurred during the period from, and including, the first day of the Market Value Averaging Period
to, and including the second scheduled Trading Day immediately prior to the Purchase Contract Settlement Date, all remaining Trading Days in the Market Value Averaging Period shall be deemed to occur on that second scheduled Trading Day immediately
prior to the Purchase Contract Settlement Date, and the daily VWAP for each of those remaining Trading Days will be the daily VWAP on such second scheduled Trading Day or, if such day is not a Trading Day, the Closing Price of the Common Stock as of
such day. 
 The “VWAP” means, in respect of Common Stock, for the relevant Trading Day, the per share volume weighted
average price on the principal exchange or quotation system on which the Common Stock is listed or admitted for trading as displayed under the heading Bloomberg VWAP on Bloomberg page SR <Equity> AQR (or its equivalent successor if such page
is not available) in respect of the period from the scheduled open of trading on the relevant Trading Day until the scheduled close of trading on the relevant Trading Day (or if such volume weighted-average price is unavailable, the market price of
one share of Common Stock on such Trading Day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by the Company). 

The “Market Value Averaging Period” means the 20 consecutive Trading Days beginning on and including the 21st scheduled Trading Day immediately preceding the Purchase Contract Settlement Date. 

  
 45 

 The “Closing Price” per share of Common Stock means, on any date of
determination, the closing sale price or, if no closing sale price is reported, the last reported sale price per share of Common Stock on the principal U.S. securities exchange on which the Common Stock is listed, or if the Common Stock is not so
listed on a U.S. securities exchange, the average of the last quoted bid and ask prices for the Common Stock in the over-the-counter market as reported by OTC Markets
Group Inc. or similar organization, or, if those bid and ask prices are not available, the market value of the Common Stock on that date as determined by a nationally recognized independent investment banking firm retained by the Company for this
purpose. 
 A “Trading Day” means, for purposes of determining a VWAP or Closing Price, a day (i) on which the
principal exchange or quotation system on which the Common Stock is listed or admitted for trading is scheduled to be open for business and (ii) on which there has not occurred or does not exist a Market Disruption Event. 

A “Market Disruption Event” means any of the following events: 

(1) any suspension of, or limitation imposed on, trading by the principal exchange or quotation system on which the Common
Stock is listed or admitted for trading during the one-hour period prior to the close of trading for the regular trading session on such exchange or quotation system (or for purposes of determining VWAP any
period or periods prior to 1:00 p.m. New York City time aggregating one half hour or longer) and whether by reason of movements in price exceeding limits permitted by the relevant exchange or quotation system or otherwise relating to the Common
Stock or in futures or option contracts relating to the Common Stock on the relevant exchange or quotation system; or 
 (2)
any event (other than a failure to open or, except for purpose of determining VWAP, a closure as described below) that disrupts or impairs the ability of market participants during the one-hour period prior to
the close of trading for the regular trading session on the principal exchange or quotation system on which the Common Stock is listed or admitted for trading (or for purposes of determining VWAP any period or periods prior to 1:00 p.m. New York
City time aggregating one half hour or longer) in general to effect transactions in, or obtain market values for, the Common Stock on the relevant exchange or quotation system or futures or options contracts relating to the Common Stock on any
relevant exchange or quotation system; or 
 (3) the failure to open of the principal exchange or quotation system on which
futures or options contracts relating to the Common Stock are traded or, except for purposes of determining VWAP, the closure of such exchange or quotation system prior to its respective scheduled closing time for the regular trading session on such
day (without regard to after hours or other trading outside the regular trading session hours) unless such earlier closing time is announced by such exchange or quotation system at least one hour prior to the earlier of the actual closing time for
the regular trading session on such day and the submission deadline for orders to be entered into such exchange or quotation system for execution at the actual closing time on such day. 

  
 46 

 (b) Each Holder of a Corporate Unit or a Treasury Unit, by its acceptance of such Unit shall
be deemed to have: 
 (i) irrevocably appointed the Purchase Contract Agent as its attorney-in-fact to enter into and perform the related Purchase Contract and this Agreement on its behalf and in the name of and on behalf of such Holder (including, without limitation, the execution of
Certificates on behalf of such Holder); 
 (ii) agreed to be bound by the terms and provisions of such Unit, including, but
not limited to, the terms and provisions of the Purchase Contract and this Agreement, for so long as such Holder remains a Holder of such Unit; 

(iii) consented to, and agreed to be bound by, the Pledge of such Holder’s right, title and interest in and to its
applicable portion of the Collateral, including the Pledged Applicable Ownership Interests in Notes, the Pledged Applicable Ownership Interests in the Treasury Portfolio or the Pledged Treasury Securities, as the case may be, pursuant to this
Agreement, and the delivery of such Collateral by the Purchase Contract Agent to the Collateral Agent; and 
 (iv) agreed
that to the extent and in the manner provided herein, but subject to the terms hereof, on the Purchase Contract Settlement Date, Proceeds of the Pledged Applicable Ownership Interests in Notes, the Pledged Applicable Ownership Interests in the
Treasury Portfolio or the Pledged Treasury Securities, as applicable, equal to the Purchase Price shall be paid by the Collateral Agent to the Company in satisfaction of such Holder’s obligations under the Purchase Contract included in such
Unit. 
 (c) Reserved. 
 (d)
Upon registration of transfer of a Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee) by the terms of this Agreement and the Purchase Contracts underlying such Certificate and the
transferor shall be released from the obligations under this Agreement and the Purchase Contracts underlying the Certificate so transferred. The Company covenants and agrees, and each Holder of a Certificate, by its acceptance thereof, likewise
shall be deemed to have covenanted and agreed, to be bound by the provisions of this paragraph. 
 (e) Promptly after the calculation of the
Settlement Rate and the Applicable Market Value, the Company shall give the Purchase Contract Agent notice thereof. All calculations and determinations of the Settlement Rate and the Applicable Market Value and any adjustments to the Reference Price
or the Threshold Appreciation Price shall be made by the Company or its agent based on their good faith calculations, and the Purchase Contract Agent shall have no responsibility with respect thereto. 

(f) If a Market Disruption Event occurs on any scheduled Trading Day during the Market Value Averaging Period, the Company shall give the
Holders and the Purchase Contract Agent notice thereof on the calendar day on which such event occurs. 

  
 47 

 Section 5.02. Remarketing. 

(a) Optional Remarketing. (i) Unless a Termination Event or a Special Event Redemption has occurred, the Company may elect, at its
option, to, on one or more occasions as specified here, engage the Remarketing Agent(s), pursuant to the terms of the Remarketing Agreement, to remarket the aggregate Notes underlying the aggregate Applicable Ownership Interests in Notes that are
components of Corporate Units, along with any Separate Notes, the holders of which have elected to participate in such remarketing pursuant to the Indenture and Section 5.02(d), over a period of five sequential Business Days selected by the
Company (any such five-Business Day period, an “Optional Remarketing Period”) that falls during the Optional Remarketing Window. 

(ii) The Company shall request that the Depository notify the Depository Participants holding Corporate Units, Treasury Units
and Separate Notes of the Company’s election to conduct an Optional Remarketing no later than fifteen calendar days prior to the first day of any Optional Remarketing Period, and the Company shall provide a copy of such request to the Purchase
Contract Agent, Collateral Agent and Custodial Agent. 
 (iii) If the Company elects to conduct an Optional Remarketing, by
4:00 p.m. (New York City time) on the Business Day immediately preceding the first day of the related Optional Remarketing Period, the Purchase Contract Agent shall notify the Remarketing Agent(s) in writing of the aggregate principal amount of
Notes underlying the Pledged Applicable Ownership Interests in Notes that are a part of the Corporate Units to be remarketed, and the Custodial Agent shall notify in writing the Remarketing Agent(s) of the aggregate principal amount of Separate
Notes (if any) to be remarketed pursuant to Section 5.02(d). Pursuant to the Remarketing Agreement, upon receipt of such notices from the Purchase Contract Agent and the Custodial Agent, the Remarketing Agent(s) will use its commercially
reasonable efforts to remarket such Notes at the applicable Remarketing Price. 
 (iv) Reserved. 

(v) Reserved. 

(vi) If the Remarketing Agent(s) is able to remarket the Notes being remarketed for at least the applicable Remarketing Price
in any Optional Remarketing in accordance with the Remarketing Agreement (a “Successful Optional Remarketing”), the Collateral Agent shall cause the Securities Intermediary to Transfer to the Remarketing Agent(s) the remarketed
Notes underlying the Pledged Applicable Ownership Interests in Notes upon confirmation of deposit to the Collateral Account of proceeds of such Successful Optional Remarketing attributable to such Notes underlying the Pledged Applicable Ownership
Interests in Notes, and the Custodial Agent shall Transfer the remarketed Separate Notes to the Remarketing Agent(s) upon confirmation of deposit to the account established by the Custodial Agent for the purpose of receiving such proceeds (the
“Separate Notes Account”) of receipt of proceeds of such Successful Optional Remarketing attributable to such Separate Notes. Settlement shall occur on the Remarketing Settlement Date. Upon deposit in the Collateral Account of such
proceeds attributable to the remarketed Notes underlying the Pledged Applicable Ownership Interest in Notes, the Collateral Agent shall (A) unless the Remarketing Treasury Portfolio shall consist of Cash, (x) instruct the Securities
Intermediary to apply an amount equal to the Remarketing Treasury Portfolio Purchase Price to purchase the Remarketing Treasury Portfolio from the dealer identified 

  
 48 

 
by the Quotation Agent pursuant to the definition of “Remarketing Treasury Portfolio Purchase Price” (the amount and issue of the Treasury Securities constituting the Remarketing
Treasury Portfolio to be determined by the Remarketing Agent(s), who shall provide such information to the Collateral Agent and the Quotation Agent, who will then determine, and notify the Collateral Agent of, the Remarketing Treasury Portfolio
Purchase Price) and (y) credit to the Collateral Account the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A) of such term), (B) if the Remarketing Treasury Portfolio shall consist of Cash, credit
to the Collateral Account Cash in an amount equal to the Remarketing Treasury Portfolio Purchase Price 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 Remarketing Settlement Date to such Holders pro rata in accordance with their interests. With respect to any Separate Notes remarketed, upon receipt of proceeds of such
Successful Optional Remarketing attributable to the remarketed Separate Notes, the Custodial Agent shall remit the proceeds of such Separate Notes sold in the Successful Optional Remarketing received from the Remarketing Agent(s) pro rata to
the holders of such Separate Notes on the Remarketing Settlement Date in accordance with the instructions provided in the form of Exhibit K. 

(vii) If there is a Successful Optional Remarketing, the Company shall cause a notice of the Successful Optional Remarketing to
be published no later than 9:00 a.m., New York City time, on the Business Day immediately following the Optional Remarketing Date. This notice shall include the Reset Rate. This notice shall be validly published by making a timely release to any
appropriate news agency, including Bloomberg Business News and the Dow Jones News Service. 
 (viii) Following the occurrence
of a Successful Optional Remarketing, the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) of such term) will be substituted as Collateral for the Pledged Applicable Ownership Interests in Notes and will
be held by the Collateral Agent in accordance with the terms hereof to secure the Obligations of each Holder of Corporate Units, and the Holders of Corporate Units and the Collateral Agent shall have such security interests, rights and obligations
with respect to the Applicable Ownership Interests in the Treasury Portfolio (as defined in clause (A)(i) of such term) as the Holder of Corporate Units and the Collateral Agent had in respect of the Pledged Applicable Ownership Interests in
Notes and the underlying Notes, subject to the Pledge thereof. Unless the context otherwise requires, any reference in this Agreement or the Certificates to the Pledged Applicable Ownership Interests in Notes shall thereupon be deemed to be a
reference to such Applicable Ownership Interests in the Treasury Portfolio (as defined in clause (A)(i) of such term). 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 (as defined in clause (A)(i) of such term) for the Pledged Applicable Ownership Interests in Notes as
Collateral. 

  
 49 

 (ix) Following a Successful Optional Remarketing, the Remarketing Agent(s)
shall remit (1) the proceeds attributable to the remarketed Notes underlying the Pledged Applicable Ownership Interest in Notes to the Collateral Agent and (2) the proceeds attributable to the remarketed Separate Notes to the Custodial
Agent for the benefit of the Holders of Separate Notes that had their Notes remarketed. 
 (x) If, in spite of its
commercially reasonable efforts, the Remarketing Agent(s) cannot remarket the Notes 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 failed (a “Failed Optional Remarketing”). Promptly after a Failed Optional Remarketing and receipt of notice thereof from the Company, the
Custodial Agent will return Separate Notes that were to be subject to such Optional Remarketing to the appropriate holders pursuant to the instructions provided in the form of Exhibit K. 

(xi) If the Company elects to remarket the Notes in any Optional Remarketing Period during the Optional Remarketing Window and
a Successful Optional Remarketing has not occurred on or prior to the last day of such Optional Remarketing Period, the Company shall cause notice of the Failed Optional Remarketing to be provided to the Custodial Agent, the Collateral Agent and the
Purchase Contract Agent and to be published no later than 9:00 a.m., New York City time, on the Business Day immediately following the last date of the Optional Remarketing Period. Any such notice shall be validly published by making a timely
release to any appropriate news agency, including Bloomberg Business News and the Dow Jones News Service. 
 (xii) The
Company will pay the Remarketing Fee in connection with any Successful Optional Remarketing. Holders whose Notes are part of a Successful Optional Remarketing will not be responsible for payment of the Remarketing Fee. 

(xiii) At any time and from time to time during any Optional Remarketing Period, prior to the announcement of a Successful
Optional Remarketing, the Company has the right to postpone such Optional Remarketing in the Company’s sole and absolute discretion. 

(b) Final Remarketing. (i) Unless a Termination Event, a Successful Optional Remarketing or a Special Event Redemption has
previously occurred, in order to dispose of the Notes underlying Pledged Applicable Ownership Interests in Notes of any Holders of Corporate Units who have not notified the Purchase Contract Agent of their intention to effect a Cash Settlement as
provided in Section 5.03(a)(i), or who have so notified the Purchase Contract Agent but failed to make such payment as required by Section 5.03(a)(ii), the Company shall engage the Remarketing Agent(s), pursuant to the terms of the
Remarketing Agreement, to remarket such Notes, along with any Separate Notes, the holders of which have elected to participate in a Final Remarketing pursuant to Section 5.02(d), over a period of one or more days selected by the Company that
fall during the Final Remarketing Period. 
 (ii) The Company shall request that the Depository notify the Depository
Participants holding Corporate Units, Treasury Units and Separate Notes of the Final Remarketing no later than fifteen calendar days prior to the first day of the Final Remarketing Period, and the Company shall provide a copy of such request to the
Purchase 

  
 50 

 
Contract Agent, Collateral Agent and Custodial Agent. In such notice, the Company shall set forth the dates of the Final Remarketing Period, the applicable procedures for holders of Separate
Notes to participate in the Final Remarketing, the applicable procedures for Holders of Corporate Units to create Treasury 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 and any other applicable procedures, including the procedures that must be followed by a holder of a Separate Note in the case of a Failed Remarketing if
such holder of Separate Notes wishes to exercise its Put Right. 
 (iii) The Purchase Contract Agent, based on the notices
specified pursuant to Section 5.03(a)(iv), 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
principal amount of Notes underlying the Pledged Applicable Ownership Interests in Notes that are to be remarketed, and the Custodial Agent shall notify in writing the Remarketing Agent(s) of the aggregate principal amount of Separate Notes (if any)
to be remarketed pursuant to Section 5.02(d). Upon receipt of notice 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 shall, on each Remarketing Date
in the Final Remarketing Period, use commercially reasonable efforts to remarket, as provided in the Remarketing Agreement, such Notes and such Separate Notes at the applicable Remarketing Price. 

(iv) Reserved. 

(v) If the Remarketing Agent(s) is able to remarket such Notes and the Separate Notes (if any) for at least the Remarketing
Price for a Final Remarketing in any Final Remarketing in accordance with the Remarketing Agreement (a “Successful Final Remarketing”), the Collateral Agent shall cause the Securities Intermediary to Transfer to the Remarketing
Agent(s) the remarketed Notes underlying the Pledged Applicable Ownership Interests in Notes upon confirmation of deposit to the Collateral Account of proceeds of such Successful Final Remarketing attributable to such Notes, and the Custodial Agent
shall Transfer the remarketed Separate Notes to the Remarketing Agent(s) upon confirmation of deposit to the Separate Notes Account of proceeds of such Successful Final Remarketing attributable to such Separate Notes. Settlement shall occur on the
Remarketing Settlement Date. Upon deposit in the Collateral Account of such proceeds attributable to the remarketed Notes underlying the Pledged Applicable Ownership in Notes, the Collateral Agent shall, on the Purchase Contract Settlement Date
instruct the Securities Intermediary to (1) remit to the Company a portion of such proceeds equal to the aggregate principal amount of remarketed Notes underlying Pledged Applicable Ownership Interests in Notes 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 (2) promptly remit the balance of such proceeds to the Purchase Contract Agent for payment
to the Holders of such Corporate Units, whereupon the Purchase Contract Agent shall make such payment on the Purchase Contract Settlement Date to such Holders pro rata in accordance with their interests. In addition, on the Purchase Contract
Settlement Date, the Securities Intermediary shall deliver to the Collateral Agent for distribution to 

  
 51 

 
the Holders of Corporate Units who have elected Cash Settlement, and paid the Purchase Price as required by Section 5.03(a)(ii), the Notes underlying the Applicable Ownership Interest in
Notes underlying such Corporate Units. With respect to any Separate Notes remarketed, upon receipt of proceeds attributable to remarketed Separate Notes, the Custodial Agent shall remit such proceeds of the Successful Final Remarketing received from
the Remarketing Agent(s) pro rata to the holders of such Separate Notes on the Purchase Contract Settlement Date in accordance with the instructions provided in the form of Exhibit K. 

(vi) Following a Successful Final Remarketing, the Remarketing Agent(s) shall remit (1) the proceeds attributable to the
remarketed Notes underlying the Pledged Applicable Ownership Interest in Notes to the Collateral Agent for application as set forth above and (2) the proceeds attributable to the remarketed Separate Notes to the Custodial Agent for the benefit
of the Holders of Separate Notes that had their Notes remarketed. 
 (vii) If there is a Successful Final Remarketing, the
Company shall cause a notice of the Successful Final Remarketing to be provided to the Purchase Contract Agent, Collateral Agent and Custodial Agent and to be published no later than 9:00 a.m., New York City time, on the Business Day immediately
following the Final Remarketing Date. This notice shall include the Reset Rate. This notice shall be validly published by making a timely release to any appropriate news agency, including Bloomberg Business News and the Dow Jones News Service. 

(viii) In connection with any Successful Final Remarketing, the Company shall cause all accrued and unpaid interest to be paid
to the Holders of the Notes, as of the relevant Record Date (as defined in the Indenture) (whether or not such Notes were remarketed in such Successful Final Remarketing), on the Purchase Contract Settlement Date in Cash. 

(ix) If, in spite of its commercially reasonable efforts, the Remarketing Agent(s) cannot remarket the Notes during the Final
Remarketing Period at a price equal to or greater than the applicable Remarketing Price or a condition precedent set forth in the Remarketing Agreement is not fulfilled, the Remarketing will be deemed to have failed (a “Failed Final
Remarketing”). 
 Following a Failed Final Remarketing, as of the Purchase Contract Settlement Date, each Holder of any Pledged
Applicable Ownership Interests in Notes, unless such Holder has (A) provided written notice in substantially the form of Exhibit M hereto prior to 4:00 p.m. (New York City time) on the Business Day immediately preceding the Purchase Contract
Settlement Date of its intention to settle the related Purchase Contract with separate cash, (B) surrendered the Certificate evidencing the Corporate Units (if they are in certificated form) or the related Book-Entry Interests, to the Purchase
Contract Agent prior to 4:00 p.m., New York City time, on the Business Day immediately preceding the Purchase Contract Settlement Date and (C) on or prior to the Business Day immediately preceding the Purchase Contract Settlement Date delivered
the Purchase Price in Cash to the Securities Intermediary for deposit in the Collateral 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 

  
 52 

 
of 20 Corporate Units), shall be deemed to have exercised such Holder’s Put Right with respect to the Notes underlying such Pledged Applicable Ownership Interests in Notes and to have
elected to apply the proceeds of the Put Price against 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 Holders’
Obligations under such Purchase Contracts. Following such application, each such Holder’s Obligations will be deemed to be satisfied in full, and the Collateral Agent shall cause the Securities Intermediary to release the Notes underlying such
Pledged Applicable Ownership Interests in Notes from the Collateral Account and shall promptly transfer such Notes to the Company. 
 Upon
(x) receipt by the Collateral Agent of a notice from the Purchase Contract Agent in substantially the form of Exhibit N hereto promptly after the receipt by the Purchase Contract Agent of a notice from a Holder of Corporate Units that such
Holder has 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 exercise of such Holder’s Put Right, 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 O 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 in 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 consistent with the instructions of the Company with respect to Cash Settlement,
(Y) promptly release from the Pledge the Notes underlying the Applicable Ownership Interest in Notes related to the Corporate Units as to which such Holder has paid such separate cash and (Z) promptly Transfer all such Notes to the
Purchase Contract Agent for distribution to such Holder, in each case, free and clear of the Pledge created hereby, whereupon the Purchase Contract Agent shall Transfer such Notes 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 Notes, and any interest payment thereon, 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 Notes and interest payments thereon, if any, are held. 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)(ix), as the case may be, to the Company, and (B) release any amounts in excess of such amount earned from such Permitted
Investments (if any) 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)(ix), as adjusted to reflect the
period of time that each such Holder’s cash was invested in such Permitted Investments. For the avoidance of doubt, nothing in this Section 5.02(b)(ix) shall prevent holders of Separate Notes from exercising their Put Right after a Failed
Final Remarketing. 
 (x) The Company has the right to postpone the Final Remarketing in the Company’s sole and absolute
discretion on any day prior to the last three Business Days of the Final Remarketing Period. 

  
 53 

 (xi) If a Successful Remarketing has not occurred on or prior to the last
day of the Final Remarketing Period, the Company shall cause a notice of the Failed Remarketing to be provided to the Purchase Contract Agent, Collateral Agent and Custodial Agent and to be published no later than 9:00 a.m., New York City time, on
the Business Day immediately following the last day of the Final Remarketing Period. This notice shall be validly published by making a timely release to any appropriate news agency, including Bloomberg Business News and the Dow Jones News Service.

 (xii) The Company will pay the Remarketing Fee in connection with any Successful Final Remarketing. Holders whose Notes
are part of a Successful Final Remarketing will not be responsible for payment of the Remarketing Fee. 
 (xiii) Following
the occurrence of a Successful Final Remarketing, proceeds attributable to the remarketed Notes underlying the Pledged Applicable Ownership in Notes will be substituted as Collateral for the Pledged Applicable Ownership Interests in Notes and will
be held by the Collateral Agent in accordance with the terms hereof to secure the Obligations of each Holder of Corporate Units, and the Collateral Agent shall have such security interests, rights and obligations with respect to such proceeds as the
Collateral Agent had in respect of the Pledged Applicable Ownership Interests in Notes. 
 (c) Reserved. 

(d) At any time following notice by the Company of a Remarketing, other than during a Blackout Period, holders of Separate Notes may elect to
have their Separate Notes remarketed in such Remarketing in the same manner as the Notes included in Corporate Units by delivering their Separate Notes along with a notice of this election, substantially in the form of Exhibit K attached hereto, to
the Custodial Agent. The Custodial Agent shall hold the Separate Notes in an account separate from the Collateral Account in which any Pledged Applicable Ownership Interests in Notes and/or any Pledged Treasury Securities shall be held. Holders
electing to have their Separate Notes remarketed shall also have the right to withdraw the election, other than during a Blackout Period, by written notice to the Collateral Agent, substantially in the form of Exhibit L 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 during the Optional Remarketing Period, each holder of Separate Notes that
elects to have its Notes remarketed shall receive for each $1,000 principal amount of Notes, the Remarketing Price Per Note. In the event of a Successful Remarketing during the Final Remarketing Period, each holder of Separate Notes that elects to
have its Notes remarketed shall receive its pro rata portion of the proceeds of such Successful Remarketing attributable to remarketed Separate Notes pursuant to 5.02(b)(v), which shall be, for each $1,000 principal amount of Notes, at least
equal to $1,000 in cash. Any accrued and unpaid interest on such Notes shall be paid in cash by the Company on the Purchase Contract Settlement Date. 

(e) For the avoidance of doubt, the right of each holder of the Notes underlying the aggregate Applicable Ownership Interests in Notes that
are components of Corporate Units (who, in the case of a Final Remarketing, have not elected Cash Settlement, and paid the Purchase Price in Cash to the Securities Intermediary, pursuant to Section 5.03) and the Separate Notes, the holders of
which have elected to participate in any Remarketing, to have such Notes remarketed 

  
 54 

 
during the Applicable Remarketing Period and sold on the Optional Remarketing Date or Final Remarketing Date, as the case may be, shall be subject to the conditions that (i) (1) the
Remarketing Agent(s) conducts an Optional Remarketing, or (2) in the case of a 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 the Optional Remarketing Date or Final Remarketing Date, as the case may be, (iii) the Remarketing Agent(s) is able to find a purchaser or purchasers for such Notes at the applicable Remarketing Price based on the Reset Rate and
(iv) each condition precedent to settlement of the remarketed Notes set forth in the Remarketing Agreement is satisfied or waived. 

(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 Notes to be remarketed in any Remarketing 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 Act). 
 Section 5.03. Cash Settlement; Payment of Purchase Price. (a) (i) Unless (1) a Termination
Event has occurred, (2) a Holder effects an Early Settlement or a Fundamental Change Early Settlement of the underlying Purchase Contract or (3) a Successful Optional Remarketing or a Special Event Redemption has occurred, each Holder of
Corporate Units shall have the right, subject to the conditions set forth below, to satisfy such Holder’s Obligations on the Purchase Contract Settlement Date with separate cash. Each Holder of Corporate Units who intends to pay separate cash
to satisfy such Holder’s Obligations under the Purchase Contract on the Purchase Contract Settlement Date must so notify the Purchase Contract Agent by presenting and surrendering at the Corporate Trust Office (1) the Certificate
evidencing the Corporate Units (if they are in certificated form) or the related Book-Entry Interests, and (2) a “Notice to Settle with Cash” substantially in the form of Exhibit E hereto completed and executed as indicated, in
each case, at any time on or after the date the Company gives notice of a Final Remarketing and prior to 4:00 p.m. (New York City time) on the second Business Day immediately preceding the first day of the Final Remarketing Period. Corporate Units
Holders may only effect such a Cash Settlement pursuant to this Section 5.03(a) in integral multiples of 20 Corporate Units. 

(ii) A Holder of a Corporate Unit who has so notified the Purchase Contract Agent of its intention to effect a Cash Settlement
in accordance with Section 5.03(a)(i) above shall pay the Purchase Price to the Securities Intermediary for deposit in the Collateral Account prior to 4:00 p.m. (New York City time) on the first Business Day immediately preceding the first day
of the Final Remarketing Period, in Cash by certified or cashier’s check or wire transfer in immediately available funds payable to or upon the order of the Securities Intermediary. 

(iii) If a Holder of a Corporate Unit fails to notify the Purchase Contract Agent of its intention to make a Cash Settlement in
accordance with Section 5.03(a)(i), or does notify the Purchase Contract Agent as provided in Section 5.03(a)(i) of its intention to pay the Purchase Price with separate cash but fails to make such payment as required by
Section 5.03(a)(ii), such Holder shall be deemed to have consented to the disposition of the Notes underlying the Pledged Applicable Ownership Interests in Notes pursuant to any Remarketing occurring in the Final Remarketing Period as set forth
in Section 5.02(b). 

  
 55 

 (iv) Promptly after 4:00 p.m. (New York City time) on the first Business Day
immediately preceding the first day of the Final Remarketing Period, the Purchase Contract Agent, based on notices received by the Purchase Contract Agent pursuant to Section 5.03(a)(i) and notice from the Securities Intermediary regarding cash
received by it prior to such time, shall notify the Collateral Agent of the aggregate principal amount of Notes to be remarketed in any Remarketing occurring in the Final Remarketing Period in a notice substantially in the form of Exhibit J hereto.

 (v) Upon (1) receipt by the Collateral Agent of a notice in the form of Exhibit J from the Purchase Contract Agent
(delivered pursuant to clause (iv) above) after the receipt by the Purchase Contract Agent of a notice in the form of Exhibit E from a Holder of Corporate Units that such Holder has elected, in accordance with Section 5.03(a)(i), to effect
a Cash Settlement and (2) the payment by such Holder of the Purchase Price in accordance with Section 5.03(a)(ii) above, then the Collateral Agent shall: 

(A) if the Company so requests, and the Collateral Agent and Securities Intermediary consent thereto, instruct the Securities
Intermediary promptly to invest any such Cash in Permitted Investments consistent with the instructions of the Company as provided for below in this Section 5.03(a)(v); 

(B) release from the Pledge the Notes underlying the Applicable Ownership Interest in Notes related to the Corporate Units as
to which such Holder has effected a Cash Settlement; and 
 (C) instruct the Securities Intermediary to Transfer all such
Notes to the Purchase Contract Agent for distribution to such Holder, in each case free and clear of the Pledge created hereby, whereupon the Purchase Contract Agent shall promptly Transfer such Notes 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 Notes, and any interest payment thereon, 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 Notes and interest payments thereon, if any, are held. 

The Company shall instruct the Collateral Agent in writing as to the type of Permitted Investments (if any) in which any such Cash shall be
invested; provided, however, that if the Company fails to deliver such written instructions by 12:00 p.m. (New York City time) on the day such Cash is received by the Collateral Agent or to be reinvested by the Securities Intermediary,
the Collateral Agent may instruct the Securities Intermediary to invest such Cash 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 Collateral Agent which
shall be effective until revoked or superseded. If no such standing instruction exists, such Cash shall remain uninvested. In no event shall the Collateral Agent or Securities Intermediary be liable for the selection of Permitted Investments or for
investment losses incurred thereon. The Collateral Agent and Securities Intermediary shall have no liability in respect of losses incurred as a result of the failure of the Company to provide timely written investment direction. 

  
 56 

 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 Cash Settlement has been effected as provided in this Section 5.03, as the case may be, and (B) release any amounts in excess of such amount earned from such Permitted Investments to the Purchase Contract Agent for
distribution to the Holders who have effected Cash Settlement, pro rata in proportion to the amount paid by such Holders under Section 5.03(a)(ii), as adjusted to reflect the period of time that each such Holder’s cash was invested
in such Permitted Investments. 
 (b) 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 Notes 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 during the period from, and including, the fifth Business Day immediately preceding the Purchase Contract Settlement Date to, and including, the Business Day immediately preceding 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 may be invested in 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 Cash shall remain uninvested. 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 either the related Pledged Treasury Securities or the related Pledged Applicable Ownership Interests in the Treasury Portfolio and the Proceeds from such Permitted Investments is in excess of the
aggregate Purchase Price, 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 Holders of the related Treasury
Units or Corporate Units, as applicable. 
 (c) 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 Cash Settlement 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. 

(d) The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates in
respect thereof to the Holder of the related Units unless the Company shall have received payment of the aggregate Purchase Price for the Common Stock to be purchased thereunder in the manner set forth herein. 

  
 57 

 Section 5.04. Issuance of Shares of Common Stock. Unless a Termination Event, an
Early Settlement or a Fundamental Change Early Settlement shall have occurred, subject to Section 5.05(b), 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 or 5.03, 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 or their designees (such certificates for shares of Common Stock, together with any dividends or distributions for which a record date and
payment date for such dividend or distribution has occurred on or after the Purchase Contract Settlement Date, being hereinafter referred to as the “Purchase Contract Settlement Fund”) to which the Holders are entitled hereunder.

 Subject to the foregoing, following book-entry transfer of a Unit or surrender of a Certificate, as the case may be, to the Purchase
Contract Agent on or after the Purchase Contract Settlement Date, Early Settlement Date or the date on which the Fundamental Change Early Settlement Right is exercised, 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) 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 5.09 and, in the case of a settlement on the Purchase Contract Settlement Date, any dividends or distributions with respect to
such shares constituting part of the Purchase Contract Settlement Fund, but without any interest thereon, and the number of Units represented by the Global Certificate shall be appropriately reduced in accordance with Applicable Procedures and
standing arrangements between the Depository and the Purchase Contract Agent, 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 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 or the beneficial owner thereof, no such registration or
transfer shall be made unless and until the Person requesting such registration or transfer shall have paid to 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. 

  
 58 

 Section 5.05. Adjustment of each Fixed Settlement Rate. (a) Each Fixed
Settlement Rate shall be subject to the following adjustments: 
 (i) 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 Fixed Settlement Rate shall be adjusted based on the following formula: 

SR1 = SR0
x (OS1 / OS0) 

where, 
 SR0 = the Fixed 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
Fixed Settlement Rate in effect immediately after the close of business on such Record Date or such Effective Date, as the case may be; 
 OS0 = the number of shares of Common Stock outstanding immediately prior to the close of business on such Record Date or 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 (i) shall become
effective as of the close of business on (x) the Record Date for such dividend or other distribution or (y) 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 
 (ii) If the Company distributes to 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 Closing Price of the Common Stock on the Business Day immediately preceding the date of the time of announcement of such issuance, the Fixed Settlement Rate shall be increased based on the following formula: 

SR1 = SR0
x (OS0 + X) / ( OS0 + Y)

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

SR1 = the Fixed Settlement Rate in effect immediately after the close of business on
such Record Date; 

  
 59 

 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 announcement for the issuance of such rights, options or warrants. 
 If any right, option or warrant
described in this clause (ii) 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 Fixed Settlement Rate shall be readjusted, as of the date of such expiration, to the Fixed Settlement Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made
on the basis of delivery or issuance of only the number of shares of Common Stock actually delivered. 
 For purposes of this
clause (ii), in determining whether any rights, options or warrants entitle the holders thereof to subscribe for or purchase shares of the Common Stock at a price per share of Common Stock less than the Closing Price of the Common Stock on the
Business Day immediately preceding the date of the time of announcement of such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration the Company
receives 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 Fixed Settlement Rate made under this clause (ii) 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. 

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

SR1 = SR0
x SP0 / (SP0 - FMV) 

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

  
 60 

 SR1 = the Fixed 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. 

Notwithstanding the foregoing, if “FMV” (as defined above) exceeds
“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 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 will be listed on a U.S. national securities exchange (a “Spin-Off”), then the Fixed Settlement Rate shall instead be increased based on the following formula: 

SR1 = SR0
x (FMV0 + MP0) / MP0 

where, 
 SR0 = the Fixed Settlement Rate in effect immediately prior to the end of the Valuation Period; 

SR1 = the Fixed Settlement Rate in effect immediately after the end of the Valuation
Period; 
 FMV0 = the average of the closing price 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 third Trading Day immediately following the
Ex-Dividend Date for such dividend or distribution with respect to the Common Stock on the NYSE or such other U.S. national or regional exchange or market that is at that time the principal exchange or market
for the Common Stock (the “Valuation Period”); and 
 MP0 = the
average of the Closing Price of the Common Stock over the Valuation Period. 

  
 61 

 The adjustment to the Fixed Settlement Rate under this clause (iii)(2) shall occur on the
last day of the Valuation Period; provided that if a Holder elects to early settle the Purchase Contracts, 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, or the Business Day immediately preceding the Purchase Contract Settlement Date, as the case may be, in determining the applicable Fixed Settlement Rate. 

If any dividend or distribution described in this clause (c) is declared but not so paid or made, the new Fixed 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. 

(iv) If any regular, quarterly Cash dividend or distribution is made to all or substantially all holders of Common Stock during
any quarterly fiscal period exceeds $0.65 per share (the “Reference Dividend”), the Fixed Settlement Rate shall be increased based on the following formula: 

SR1 = SR0
x [(SP0 - T) / (SP0 - C)] 

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

SR1 = the Fixed Settlement Rate in effect immediately after the close of business on
such Record Date; 
 SP0 = the Closing Price of the Common Stock on the Record Date
for such distribution; 
 C = the amount in Cash per share the Company distributes to holders of Common Stock; and 

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. 
 Notwithstanding the foregoing, if “C” (as defined above) exceeds “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 Fixed Settlement Rate is adjusted, other than
pursuant to this clause (iv). 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. 

  
 62 

 If any dividend or distribution described in this clause (iv) is declared but not so
paid or made, the new Maximum Settlement Rates 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. 
 (v) 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 Fixed Settlement Rate shall be increased based on the following formula: 

SR1 = SR0
x [(FMV + (SP1 x OS1)] / (SP1 x
OS0) 
 where, 

SR0 = the Fixed Settlement Rate in effect immediately prior to the close of business on
the Trading Day on which such tender or exchange offer expires; 
 SR1 = the Fixed
Settlement Rate in effect immediately after the close of business on the Trading Day immediately following the date 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 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; 
 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 for the Trading Day next succeeding the
date such tender or exchange offer expires. 

  
 63 

 The adjustment to the Fixed Settlement Rate under this clause (iv) shall occur at the
close of business on the Trading Day on which such tender or exchange offer expires. 
 (vi) Reserved. 

(vii) (1) If any adjustments are made to each Fixed Settlement Rates pursuant to this Section 5.05(a), an adjustment
shall also be made to the Reference Price and the Threshold Appreciation Price solely to determine which of the clauses of the definition of Settlement Rate in Section 5.01(a) will be applicable to determine the Settlement Rate with respect to
the Purchase Contract Settlement Date or any Fundamental Change Early Settlement Date. Such adjustment shall be made by multiplying the Reference Price by a fraction, the numerator of which is the Maximum Settlement Rate immediately before such
adjustment and the denominator of which shall be the Maximum Settlement Rate immediately after such adjustment and by multiplying the Threshold Appreciation Price by a fraction, the numerator of which is the Minimum Settlement Rate immediately
before such adjustment and the denominator of which shall be the Minimum Settlement Rate immediately after such adjustment (rounded, in each case, to the nearest $0.0001). In addition, if any adjustment to the Fixed Settlement Rates becomes
effective, or any effective date, expiration time, Ex Date or record date for any stock split or reverse stock split, tender or exchange offer, issuance, dividend or distribution (relating to a required Fixed 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 Early Settlement or Fundamental Change Early Settlement, the relevant Early
Settlement Date or the date on which the Fundamental Change Early Settlement Right is exercised 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 Fixed Settlement Rates and/or the number of shares of Common Stock deliverable upon settlement of the Purchase Contract, in each case, consistent with the methodology used to determine the
anti-dilution adjustments set forth above in paragraphs (a)(i) to (a)(v) of this Section 5.05. If any adjustment to the Fixed Settlement Rates becomes effective, or any effective date, expiration time, Ex Date or record date for any stock
split or reverse stock split, tender or exchange offer, issuance, dividend or distribution (relating to a required Fixed Settlement Rate adjustment) occurs, during the period used to determine the Stock Price or any other averaging 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 above in paragraphs (a)(i) to (a)(v) of this Section 5.05. 

(2) No adjustment to the Fixed Settlement Rates will be made pursuant to this Section 5.05(a) if Holders participate, as a
result of holding the Units 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 a number of shares of the Common Stock per Unit 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. 

  
 64 

 (viii) All adjustments to the Fixed Settlement Rate shall be calculated by
the Company to the nearest 1/10,000th of a share of Common Stock. No adjustment to the Fixed Settlement Rates shall be required unless such adjustment would require an increase or decrease of at least one percent in one or both Fixed Settlement
Rates; provided, that if any adjustment is not required to be made because it would not change one or both of the Fixed Settlement Rates by at least one percent, the adjustment shall be carried forward and taken into account in any subsequent
adjustment; provided further that notwithstanding whether or not such one percent threshold shall have been met, all such adjustments under this Section 5.05(a) shall be made no 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 of the Purchase
Contracts pursuant to Section 5.01, Section 5.05(b)(ii) or Section 5.08. 
 (ix) The Company may increase the
Fixed Settlement Rates, in addition to those required by this Section 5.05(a), if the Board of Directors deems it advisable in order to avoid or diminish any income tax to any holders of 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. Any such discretionary adjustment must be in effect for at least 20 Business Days, and the Company
shall deliver written notice of the amount of such increase and the number of days for which it will be in effect to the Holders and Purchase Contract Agent at least 15 days prior to such adjustment taking effect. 

(x) To the extent the Company has a shareholder rights plan involving the issuance of share purchase rights or other similar
rights (the “Rights”) to all or substantially all holders of the Common Stock in effect upon settlement of a Purchase Contract, a Holder shall be entitled to receive upon settlement of any Purchase Contract, in addition to the
shares of Common Stock issuable upon settlement of such Purchase Contract, the related Rights for the Common Stock under the shareholder rights plan, unless prior to such settlement, such Rights under the shareholder rights plan have separated from
the Common Stock, in which case each Fixed Settlement Rate shall be adjusted at the time of separation as if the Company made a distribution to all holders of the Common Stock as provided in Section 5.05(a)(iii), subject to readjustment in the
event of the expiration, termination or redemption of the Rights. 
 (b) (i) 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 the Company would otherwise be required to deliver hereunder. An “Exchange Property Unit” is the kind and amount of common stock, other securities, other property or assets (including cash or any combination thereof)
receivable in such Reorganization Event (without any interest thereon, and without any right to dividends or distributions thereon that have a record date that is prior to the applicable Settlement Date) per share of Common Stock by a holder of
Common Stock that is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a “Constituent
Person”), or an Affiliate of a Constituent Person to the extent such Reorganization Event provides for different treatment of Common Stock held by a Constituent Person and/or the Affiliates of a

  
 65 

 
Constituent Person, on the one hand, and non-Affiliates of a Constituent Person, on the other hand. 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 such transaction, the Exchange Property Unit that Holders of the Corporate Units or Treasury Units would have been entitled to receive
shall 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 merger or the Person which acquires the assets of the Company shall execute and deliver to the Purchase Contract Agent an agreement supplemental hereto providing
that the Holder of each Unit that remains Outstanding after the Reorganization Event (if any) shall have the rights provided by this Section 5.05(b). 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 Fixed Settlement Rates, which, for events subsequent to the effective date of such Reorganization Event, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 5.05. The provisions of this Section 5.05(b)(i) shall similarly apply to successive Reorganization Events. 

When the Company executes a supplemental agreement pursuant to this Section 5.05(b)(i), the Company shall promptly file with the Purchase
Contract Agent an Officers’ Certificate and an Opinion of Counsel briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise an Exchange Property Unit after any such Reorganization
Event, any adjustments to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental agreement
to be mailed to each Holder within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental agreement. The Company shall not become a party to any Reorganization Event unless its
terms are consistent with this Section 5.05(b)(i). 
 In connection with any Reorganization Event, the Reference Dividend shall be
subject to adjustment as described in clause (A), clause (B) or clause (C) below, as the case may be. 
 (A) In the case of a
Reorganization Event in which the Exchange Property Unit (determined, as appropriate, as set forth above and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock (the “Merger Common
Stock”), the Reference Dividend at and after the effective time of such Reorganization Event will be equal to (x) the Reference Dividend immediately prior to the effective time of such Reorganization Event, divided by
(y) the number of shares of Merger Common Stock that a holder of one share of Common Stock would receive in such Reorganization Event (such quotient rounded to the nearest $0.0001). 

(B) In the case of a Reorganization Event in which the Exchange Property Unit (determined, as appropriate, as set forth above and excluding
any dissenters’ appraisal rights) is composed in part of shares of Merger Common Stock, the Reference Dividend at and after the effective time of such Reorganization Event will be equal to (x) the Reference Dividend immediately prior to
the effective time of such Reorganization Event, multiplied by (y) the Merger Valuation Percentage for such Reorganization Event (such product rounded to the nearest $0.0001). 

  
 66 

 (C) For the avoidance of doubt, in the case of a Reorganization Event in which the Exchange
Property Unit (determined, as appropriate, as set forth above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other than shares of common stock, the Reference Dividend at and after the effective time of
such Reorganization Event will be equal to zero. 
 For purposes of calculating the “value” of an Exchange Property Unit, or any
cash, securities or other property included therein, for purposes of (I) this Section 5.05(b)(i) and (II) the definitions of “Merger Valuation Percentage” and “Fundamental Change,” (x) the value of any cash
shall be the face amount thereof, (y) the value of any common stock shall be (A) in the case of clause (I) above, the average of the volume-weighted average prices of such common stock on each Trading Day during the Market Value
Averaging Period (subject to Section 5.05(a)(vii)(1)) and (B) in the case of clause (II) above, the Closing Price of such common stock (determined as if references in the definition of “Closing Price” to “Common
Stock” referred instead to such common stock) on the relevant effective date (or, if such day is not a Trading Day, the immediately following Trading Day) and (z) the value of any other property, including securities other than any such
common stock, included in the Exchange Property Unit, shall be the fair market value of such property over the Market Value Averaging Period, in the case of clause (I) above, or on the applicable effective date (or, if such day is not a Trading
Day, the immediately following Trading Day), in the case of clause (II) above (in each case, as determined in good faith by the Board of Directors, whose determination shall be described in a Board Resolution). 

(ii) If a Fundamental Change occurs prior to the 20th Business Day preceding the Purchase Contract Settlement Date, then
following such Fundamental Change, each Holder of a Purchase Contract shall have the right (“Fundamental Change Early Settlement Right”) to accelerate and settle (“Fundamental Change Early Settlement”) such Purchase
Contract, upon the conditions set forth below, on the Fundamental Change Early Settlement Date at the Settlement Rate determined as if the Applicable Market Value equaled the Stock Price (as defined below), plus an additional make-whole amount of
shares of Common Stock (the “Make-Whole Shares”), subject to adjustment under Section 5.05(a)(vii), and receive payment of cash in lieu of any fraction of a share, as provided in Section 5.09; provided that no Fundamental
Change Early Settlement will be permitted pursuant to this Section 5.05(b)(ii) unless, at the time such Fundamental Change Early Settlement is effected, there is an effective Registration Statement with respect to any securities 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, (A) the Company shall, promptly after the date on which the Holder attempts to effect a Fundamental Change Early Settlement, so notify such Holder, and (B) the Company agrees to use its commercially
reasonable efforts to (x) have in effect throughout the Fundamental Change Exercise Period 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 for so long as there is a material business transaction or
development that has not yet been publicly disclosed (but in no event for a period longer than 90 days), the Company will not be required to file such Registration 

  
 67 

 
Statement or provide such a Prospectus, and a Fundamental Change Early Settlement Right will not be available, until the Company has publicly disclosed such transaction or development;
provided that the Company shall use 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 or a Blackout Period is continuing, the Holder’s exercise of such right shall be void unless
and until such a Registration Statement is effective and no Blackout Period is continuing. The Fundamental Change Exercise Period shall be extended by the number of days during such period on which no such Registration Statement is effective or a
Blackout Period is continuing (provided that the Fundamental Change Exercise Period shall not be extended beyond the fourth Business Day preceding the Purchase Contract Settlement Date) and the Fundamental Change Early Settlement Date shall
be postponed to the third Business Day following the end of the Fundamental Change Exercise Period. If, but for the proviso contained 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 all Holders of Units on the Purchase Contract Settlement Date the applicable number of Make-Whole Shares in addition to a number of shares equal to the Settlement Rate, determined
as if the Applicable Market Value were equal to the relevant Stock Price. 
 The Company shall provide written notice to Holders of Units
and the Purchase Contract Agent of the completion of a Fundamental Change within 10 Business Days after the Effective Date (as hereinafter defined) of a Fundamental Change, which shall specify (i) an early settlement date (subject to
postponement, as set forth above, the “Fundamental Change Early Settlement Date”), which shall be at least 10 days after the date of the notice but no later than the earlier of (A) 20 days after the date of such notice and
(B) one Business Day prior to the Purchase Contract Settlement Date, on which date the Company will deliver shares of Common Stock to Holders who exercise the Fundamental Change Early Settlement Right, (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 cash, securities and other consideration receivable by
the Holder upon 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. 
 Corporate Units Holders and Treasury Units Holders may
only effect Fundamental Change Early Settlement pursuant to this Section 5.05(b)(ii) in integral multiples of 20 Corporate Units or Treasury Units, as the case may be; provided that if Applicable Ownership Interests in the Treasury
Portfolio have replaced Applicable Ownership Interests in Notes as a component of the Corporate Units, Corporate Units Holders may only effect Fundamental Change Early Settlement pursuant to this Section 5.05(b)(ii) in such integral multiples
of Corporate Units as may be determined the Company or, in the case of a Remarketing, by the Remarketing Agent upon a successful Remarketing. 

  
 68 

 In order to exercise the Fundamental Change Early Settlement Right 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 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 period, subject to extension as set forth above, the “Fundamental Change Exercise
Period”) a notice of such election in the form attached thereto and 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 Fundamental Change Early Settlement on the reverse thereof duly completed, and payment of the Purchase Price for each Purchase Contract being settled in immediately available funds. 

In the event that Units are held by or through DTC or another Depository, the exercise of the right to effect Fundamental Change Early
Settlement shall occur in conformity with the Applicable Procedures and standing arrangements between DTC or such Depository and the Purchase Contract Agent. 

Upon receipt of any 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, and notify the Collateral Agent that all the conditions necessary for a Fundamental Change Early Settlement by a Holder of Units 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 notice from the Purchase Contract Agent set forth in the preceding paragraph, the Collateral Agent
shall release from the Pledge, (1) the Notes underlying the Pledged Applicable Ownership Interests in Notes or the Pledged Applicable Ownership Interests in the Treasury Portfolio, as the case may be, in the case of a Holder of Corporate Units,
or (2) the Pledged Treasury Securities, in the case of a Holder of Treasury Units, in each case relating to the Units containing the Purchase Contracts as to which such Holder has elected to effect Fundamental Change Early Settlement, and shall
instruct the Securities Intermediary to Transfer all such Pledged Applicable Ownership Interests in the Treasury Portfolio (and the related Applicable Ownership Interests in the Treasury Portfolio as specified in clause (A)(ii) or B(ii) of the
definition thereof, as the case may be) or Notes underlying Pledged Applicable Ownership Interests in Notes or Pledged Treasury Securities, as the case may be, to the Purchase Contract Agent for distribution to such Holder, in each case free and
clear of the Pledge created hereby. 
 If a Holder exercises the Fundamental Change Early Settlement Right in accordance with the provisions
of this Section 5.05(b)(ii), the Company will deliver (or will cause the Purchase Contract Agent 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: 
 (A) a number of shares of Common Stock (or Exchange Property Units, if applicable)
equal to the Settlement Rate determined pursuant to the first paragraph of this Section 5.05(b)(ii) plus the applicable Make-Whole Shares determined as set forth in Section 5.05(b)(iii); 

  
 69 

 (B) the amount of any accrued and unpaid Contract Adjustment Payments
(including any deferred Contract Adjustment Payments and Compounded Contract Adjustment Payments thereon) to, but excluding, the Fundamental Change Early Settlement Date, unless the date on which the Fundamental Change Early Settlement Right is
exercised occurs following any Record Date and prior to the related scheduled Contract Adjustment Payment Date, and the Company is not deferring the related Contract Adjustment Payment, in which case the Company shall instead pay all accrued and
unpaid Contract Adjustment Payments to the Holder as of such Record Date; 
 (C) the Notes, the Applicable Ownership
Interests in the Treasury Portfolio or Treasury Securities, as the case may be, related to each Unit with respect to which the Holder is effecting a Fundamental Change Early Settlement, free and clear of the Pledge created hereby; and 

(D) if so required under the Securities Act, a Prospectus as contemplated by this Section 5.05(b)(ii). 

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 the Purchase Contract Agent shall execute on behalf of the Holder, 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. 

(iii) The number of Make-Whole Shares per Purchase Contract deliverable upon a Fundamental Change Early Settlement will be
calculated by the Company and will 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 such Fundamental Change.
The “Stock Price” in such Fundamental Change will be: 
 (A) if holders of Common Stock receive only cash in a
Fundamental Change described in clause (b) of the definition of Fundamental Change, the cash amount paid per share of the Common Stock; and 

(B) otherwise, the average of the Closing Prices of the Common Stock over the 20 Trading Day period ending on the Trading Day
immediately preceding the Effective Date of such Fundamental Change. 

  
 70 

 The Stock Prices set forth in the second row of the table (i.e., the column headers)
shall be adjusted upon the occurrence of those events set forth in Section 5.05(a) requiring anti-dilution adjustments to the Fixed Settlement Rates. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the applicable Fixed Settlement Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the same Fixed Settlement Rate as so
adjusted. Each of the Make-Whole Shares amounts in the table will be subject to adjustment in the same manner and at the same time as the Fixed Settlement Rates as set forth under Section 5.05(a).

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

 (1) if the Stock Price is between two Stock Prices on the table or the Effective Date is between two Effective Dates on
the table, the amount of Make-Whole Shares will be determined by straight line interpolation between the Make-Whole Share amounts set forth for the higher and lower Stock Prices and the earlier and later Effective Dates based on a 365-day or 366-day year, as applicable; 
 (2) if
the Stock Price is in excess of $175.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the second row of the table as set forth above), then the Make-Whole Share amount will be zero; and 

(3) if the Stock Price is less than $15.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in
the second row of the table as set forth above), (the “Minimum Stock Price”), then the Make-Whole Share amount will be determined as if the Stock Price equaled the Minimum Stock Price, using straight line interpolation, as set forth
in clause (1) above, if the Effective Date is between two Effective Dates on the table. 
 (c) Except as described in
Section 5.05(a) and (b) above, the Fixed Settlement Rates shall not be adjusted: 
 (1) 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; 
 (2) 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; 

(3) 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; 

  
 71 

 (4) for a change in the par value or no par value of the Common Stock; or

 (5) for accumulated and unpaid Contract Adjustment Payments. 

(d) All calculations and determinations pursuant to this Section 5.05 shall be made by the Company or its agent in good faith and the
Purchase Contract Agent shall have no responsibility with respect to such calculations and determinations. 
 Section 5.06. Notice
of Adjustments and Certain Other Events. (a) Whenever the Fixed Settlement Rates are adjusted as herein provided, the Company shall, as soon as practicable following the occurrence of an event that requires an adjustment pursuant to
Section 5.05 (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware): 
 (i)
compute each adjusted Fixed Settlement Rate in accordance with Section 5.05 and prepare and transmit to the Purchase Contract Agent an Officers’ Certificate setting forth each adjusted Fixed Settlement Rate, the method of calculation
thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and 
 (ii)
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 each Fixed Settlement Rate was determined
and setting forth each adjusted Fixed Settlement Rate. 
 (b) 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 each Fixed 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 Officers’ Certificate delivered pursuant to Section 5.06(a)(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 Officers’ 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 5.07. Termination Event; Notice. 

(a) The Purchase Contracts and all obligations and rights of the Company and the Holders thereunder, including the Holders’ obligation
and right to purchase and receive shares of Common Stock and to receive accrued and unpaid Contract Adjustment Payments (including any deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon)), 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 

  
 72 

 
Contract Settlement Date, a Termination Event shall have occurred. In the event of such a termination of the Purchase Contracts as a result of a Termination Event, Holders of such Purchase
Contracts will not have a claim in bankruptcy under the Purchase Contract with respect to the Company’s issuance of shares of Common Stock or the right to receive Contract Adjustment Payments. 

(b) Upon and after the occurrence of a Termination Event, the Units shall thereafter represent the right to receive the Notes (or security
entitlements with respect thereto) underlying the Applicable Ownership Interests in Notes, the Treasury Securities 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 3.15. Upon the occurrence of a Termination Event, (i) the Company shall promptly 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 3.15, release the Notes (or security entitlements with respect thereto) underlying the Pledged
Applicable Ownership Interests in Notes or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of Applicable Ownership Interest in the Treasury Portfolio, as the case may be)
forming a part of each Corporate Unit or the Treasury Securities forming a part of each Treasury Unit, as the case may be, and any other Collateral from the Pledge. 

Section 5.08. Early Settlement. (a) Subject to and upon compliance with the provisions of this Section 5.08, at the
option of the Holder thereof, Purchase Contracts underlying Units may be settled early (“Early Settlement”) at any time prior to 4:00 p.m., New York City time, on the second Business Day immediately preceding the Purchase
Contract Settlement Date, other than during a Blackout Period in the case of Corporate Units; provided that no Early Settlement will be permitted unless, at the time such Early Settlement is effected, there is an effective Registration
Statement with respect to any securities 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, (A) the Company shall, promptly after the date on which the Holder attempts to effect an Early Settlement, so notify such Holder, and (B) the Company agrees to use
its commercially reasonable efforts to (i) have in effect on 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 file such Registration Statement or 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 shall use 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 right to effect Early Settlement 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.

  
 73 

 (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 second Business Day immediately preceding the Purchase
Contract Settlement Date, other than during a Blackout Period in the case of Corporate Units, such Certificate to the Purchase Contract Agent at the Corporate Trust Office, duly endorsed for transfer to the Company or in blank with the form of
Election to Settle Early in the form attached thereto duly completed and accompanied by payment (payable to the Company in immediately available funds) in an amount (the “Early Settlement Amount”) equal to: 

(i) (A) the Stated Amount, multiplied by (B) the number of Purchase Contracts with respect to which the Holder has
elected to effect Early Settlement in accordance with this Section 5.08, plus 
 (ii) if the Early Settlement
Date occurs during the period from the close of business on any Record Date next preceding any Contract Adjustment Payment Date to the opening of business on such Contract Adjustment Payment Date, an amount equal to the Contract Adjustment Payments
payable on such Contract Adjustment Payment Date, unless the Company elected to defer 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 Depository. 

If the foregoing requirements are first satisfied with respect to Purchase Contracts underlying any Units 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 such Certificate and 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 confirm in writing. The Purchase Contract
Agent shall then notify the Collateral Agent that (A) such Holder has elected to effect an Early Settlement, which notice shall set forth the number of such Purchase Contracts as to which such Holder has elected to effect 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 Early Settlement Amount. 

Upon receipt by the Collateral Agent of the notice from the Purchase Contract Agent set forth in the preceding paragraph, the Collateral Agent
shall release from the Pledge, (1) in the case of a Holder of Corporate Units, the Notes underlying the Pledged Applicable Ownership Interests in Notes, 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 

  
 74 

 
Holder of Treasury Units, Pledged Treasury Securities, in each case relating to the Units containing the 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 (and the related Applicable Ownership Interests in the Treasury Portfolio as specified in clause (A)(ii) or (B)(ii)
of the definition thereof, as the case may be) or Notes underlying such Pledged Applicable Ownership Interests in Notes or Pledged Treasury Securities, as the case may be, to the Purchase Contract Agent for distribution to such Holder, 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 5.08 in integral multiples of 20 Corporate Units or 20 Treasury Units, as the case may be; provided that if Applicable Ownership Interests in the Treasury Portfolio have replaced Applicable Ownership Interests in Notes as a
component of the Corporate Units, Corporate Units Holders may only effect Early Settlement pursuant to this Section 5.08 in such integral multiples of Corporate Units as may be determined the Company or, in the case of a Remarketing, by the
Remarketing Agent upon a successful Remarketing. 
 (c) Upon Early Settlement of Purchase Contracts by a Holder of the related Units, on the
applicable Settlement Date: 
 (i) such Holder shall be entitled to receive, and the Company will deliver to the Purchase
Contract Agent for delivery to such Holder, a number of shares of Common Stock (or in the case of an Early Settlement following a Reorganization Event, a number of Exchange Property Units) equal to the applicable Minimum Settlement Rate as in effect
on the Early Settlement Date for each Purchase Contract as to which Early Settlement is effected, subject to adjustment under Section 5.05(a)(vii), together with payment in lieu of any fraction of a share, as provided in Section 5.09; 

(ii) such Holder shall be entitled to receive, and the Securities Intermediary will deliver to the Purchase Contract Agent for
delivery to such Holder, the Notes, the Applicable Ownership Interest in the Treasury Portfolio or the Treasury Securities, as the case may be, related to the Corporate Units or Treasury Units free and clear of the Company’s security interest;
and 
 (iii) the Holder will be entitled to receive, and the Company shall be obligated to pay, any accrued and unpaid
Contract Adjustment Payments (including any accrued and unpaid deferred Contract Adjustment Payments and Compounded Contract Adjustment Payments thereon) to, but excluding, the Contract Adjustment Payment Date immediately preceding the Early
Settlement Date. 
 Upon any Early Settlement, the Holder’s right to receive future Contract Adjustment Payments and any accrued and
unpaid Contract Adjustment Payments for the period since the most recent Contract Adjustment Payment Date (including any accrued and unpaid deferred Contract Adjustment Payments and Compounded Contract Adjustment Payments thereon) will terminate.

 (d) Reserved. 

  
 75 

 (e) Upon Early Settlement of any Purchase Contracts, and subject to receipt of shares of
Common Stock or Exchange Property Units from the Company and the Notes, the Applicable Ownership Interests in the Treasury Portfolio or 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: 

(i) transfer to the Holder (or its designee) the Notes, the Applicable Ownership Interests in the Treasury Portfolio or
Treasury Securities, as the case may be, related to such Units, 
 (ii) deliver to the Holder (or its designee) a certificate
or certificates for the full number of shares of Common Stock or Exchange Property Units deliverable upon such Early Settlement, together with payment in lieu of any fraction of a share, as provided in Section 5.09, and 

(iii) if so required under the Securities Act, deliver a Prospectus for the shares of Common Stock or other securities
deliverable upon such Early Settlement as contemplated by Section 5.08(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, 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 5.09. 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. If Certificates evidencing more than one Purchase Contract shall be surrendered for
settlement at one time by the same Holder, the number of full shares of Common Stock which shall be delivered upon settlement shall be computed on the basis of the aggregate number of Purchase Contracts evidenced by the Certificates so surrendered.
Instead of any fractional share of Common Stock that would otherwise be deliverable upon settlement of any Purchase Contracts on the Purchase Contract Settlement Date, or upon Early Settlement or Fundamental Change Early Settlement, the Company,
through the Purchase Contract Agent, shall make a cash payment 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, in the case of any Early Settlement or Fundamental Change Early Settlement, the Closing Price of the Common Stock on the Trading Day immediately
preceding the relevant Settlement Date). 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 5.09 in a timely manner. 

  
 76 

 Section 5.10. 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 that the Company shall not be required to pay any such tax or taxes which 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 or Beneficial Owner 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 or Beneficial Owner, 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 either has been paid or is not payable. 

Section 5.11. Contract Adjustment Payments. (a) Subject to the provisions of this Section 5.11 and Section 5.12,
the Company shall pay, on each Contract Adjustment Payment Date, the Contract Adjustment Payments payable in respect of each Purchase Contract to the Person in whose name the relevant Certificate is registered at the close of business on the Record
Date relating to such Contract Adjustment Payment Date. The Contract Adjustment Payments will be payable at the office of the Purchase Contract Agent or its agent, which agent shall maintain an office in the continental United States of America for
that purpose; provided that, subject to any applicable laws and regulations, as long as the Units are in global form, the Contract Adjustment Payments shall be payable in accordance with Applicable Procedures of the Depository. If the
book-entry system for the Units has been terminated, the Contract Adjustment Payments will be payable by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or, if such
Person so requests and designates an account in writing to the Purchase Contract Agent at least five Business Days prior to the Contract Adjustment Payment Date, by wire transfer to such account. If any date on which Contract Adjustment Payments are
to be made is not a Business Day, then payment of the Contract Adjustment Payments payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay). Contract
Adjustment Payments payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. The Contract Adjustment Payments will accrue from the
date of this Agreement. For the avoidance of doubt, subject to the Company’s right to defer Contract Adjustment Payments pursuant to Section 5.12, each Holder on any Record Date shall be entitled to receive the full Contract Adjustment
Payment due on the related Contract Adjustment Payment Date regardless of whether such Holder elects to settle the relevant Purchase Contract early (whether pursuant to Section 5.05(b)(ii) or Section 5.08) following such Record Date. 

(b) Upon the occurrence of a Termination Event, the Company’s obligation to pay future Contract Adjustment Payments (including any
accrued and unpaid 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 and deferred Contract Adjustment Payments (including Compounded Contract Adjustment
Payments thereon), that was carried by the Purchase Contracts underlying such other Certificates. 

  
 77 

 (d) The Company’s obligations (collectively, the “CAP Obligations”)
with respect to Contract Adjustment Payments and deferred Contract Adjustment Payments (including Compounded Contract Adjustment Payments thereon), if any, shall be subordinated and junior in right of payment to any existing and future Priority
Indebtedness of the Company, including the Notes. The CAP Obligations shall rank on a parity with all other indebtedness and obligations of the Company that are so subordinated. 

In the case of any 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, all obligations of the Company to holders of Priority Indebtedness of the
Company, including the Notes, shall be entitled to be paid in full before any payment shall be made on account of the CAP Obligations. In the event of any such proceeding, after payment in full of all sums owing with respect to Priority Indebtedness
of the Company, the Holders of the Units, together with the holders of any obligations of the Company ranking on a parity with the CAP Obligations, shall be entitled to be paid from the remaining assets of the Company the amounts at the time due and
owing on account of the CAP Obligations and such obligations ranking on a parity with the CAP Obligations before any payment or other distribution, whether in cash, property or otherwise, shall be made on account of any capital stock or any
obligations of the Company ranking junior to the CAP Obligations. In addition, in the event of any such proceeding, if any payment or distribution of assets of the Company of any kind or character whether in cash, property or securities, including
any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the CAP Obligations shall be received by the Purchase Contract Agent or the
Holders of the Units in respect of the CAP Obligations before all Priority Indebtedness of the Company is paid in full, such payment or distribution shall be held in trust for the benefit of and shall be paid over to the holders of such Priority
Indebtedness of the Company or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Priority Indebtedness of the Company may have been issued, ratably, for
application to the payment of all Priority Indebtedness of the Company remaining unpaid until all such Priority Indebtedness of the Company shall have been paid in full, after giving effect to any concurrent payment or distribution to the holders of
such Priority Indebtedness of the Company. Nothing in the provisions of Section 5.11(d) through (n) shall apply to claims of, or payments to, the Purchase Contract Agent under or pursuant to Section 7.07. 

The subordination provisions of this sub-section (d) and
sub-section (l) below shall not be applicable to amounts at the time due and owing with respect to the CAP Obligations for the payment of which funds have been deposited in trust for the benefit of the
Holders; nor shall such provisions impair any rights, interests, or powers of any secured creditor of the Company in respect of any security the creation of which is not prohibited by the provisions of this Agreement, the Units or the Purchase
Contracts. 

  
 78 

 The Company shall give written notice to the Purchase Contract Agent within 10 Business Days
after the occurrence of (i) any 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, (ii) any “Event of Default” described in Section 801(d) or (e)] of the Base Indenture, or
(iii) any event specified in the first sentence of the second paragraph of Section 5.11(d). The Purchase Contract Agent, subject to the provisions of Section 7.01, shall be entitled to assume that, and may act as if, no such event
referred to in the preceding sentence has occurred unless a Responsible Officer of the Purchase Contract Agent has received at the Corporate Trust Office from the Company or any one or more holders of Priority Indebtedness of the Company or any
trustee or representative therefor (who shall have been certified or otherwise established to the satisfaction of the Purchase Contract Agent to be such a holder or trustee or representative) written notice thereof. Upon any distribution of assets
of the Company referred to in the provisions of Section 5.11(d) through (n), the Purchase Contract Agent and Holders of the Units shall be entitled to rely upon any order or decree of a court of competent jurisdiction in which proceedings
relating to any event specified in the first sentence of this paragraph are pending for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Priority Indebtedness of the Company, the amount thereof
or payable thereon, the amount or amounts paid or distributed thereon, and all other facts pertinent thereto or to the provisions of Section 5.11(d) through (n), and the Purchase Contract Agent, subject to the provisions of Article 7, and
the Holders of the Units shall be entitled to rely upon a certificate of the liquidating trustee or agent or other person making any distribution to the Purchase Contract Agent or to the Holders of the Units for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Priority Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to the
provisions of Section 5.11(d) through (n). In the absence of any such liquidating trustee, agent or other person, the Purchase Contract Agent shall be entitled to rely upon a written notice by a Person representing himself to be a holder of
Priority Indebtedness of the Company (or a trustee or representative on behalf of such holder) as evidence that such Person is a holder of such Priority Indebtedness (or is such a trustee or representative). In the event that the Purchase Contract
Agent determines, in good faith, that further evidence is required with respect to the right of any Person, as a holder of Priority Indebtedness of the Company, to participate in any payment or distribution pursuant to the provisions of
Section 5.11(d) through (n), the Purchase Contract Agent may request such Person to furnish evidence to the reasonable satisfaction of the Purchase Contract Agent as to the amount of such Priority Indebtedness of the Company held by such
Person, as to the extent to which such Person is entitled to participation in such payment or distribution, and as to other facts pertinent to the rights of such Person under the provisions of Section 5.11(d) through (n), and if such evidence
is not furnished, the Purchase Contract Agent may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

(e) Nothing contained in the provisions of Section 5.11(d) through (n) or elsewhere in this Agreement, the Units or the Purchase
Contracts is intended to or shall impair, as between the Company and the Holders of the Units, the obligation of the Company, which is absolute and unconditional, to satisfy the CAP Obligations when, where and as the same shall become due and
payable, all in accordance with the terms of this Agreement, the Units and the Purchase Contracts, or is intended to or shall affect the relative rights of such Holders and creditors of the Company other than the holders of the Priority Indebtedness
of the Company, nor shall anything herein or therein prevent the Purchase Contract Agent or the Holder of any Unit from exercising all remedies otherwise permitted by applicable law upon a failure of the Company to satisfy the CAP Obligations,
subject to the rights, if any, under the provisions of Section 5.11(d) through (n) of the holders of Priority Indebtedness of the Company in respect of cash, property, or securities of the Company received in respect of the CAP Obligations
upon the exercise of any such remedy. 

  
 79 

 (f) With respect to the holders of Priority Indebtedness of the Company, the Purchase
Contract Agent undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in the provisions of Section 5.11(d) through (n), and no implied covenants or obligations with respect to the holders of
Priority Indebtedness of the Company shall be read into this Agreement, the Units or the Purchase Contracts against the Purchase Contract Agent. The Purchase Contract Agent shall not be deemed to owe any fiduciary duty to the holders of Priority
Indebtedness of the Company. 
 (g) Notwithstanding any of the provisions of Section 5.11(d) through (n) or any other provisions
of this Agreement, the Units or the Purchase Contracts, the Purchase Contract Agent shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of any payment of moneys to or by the Purchase Contract
Agent unless and until a Responsible Officer of the Purchase Contract Agent shall have received at the Corporate Trust Office written notice thereof from the Company or from one or more holders of Priority Indebtedness of the Company or from any
trustee therefor or representative thereof who shall have been certified by the Company or otherwise established to the reasonable satisfaction of the Purchase Contract Agent to be such a holder or trustee or representative; and, prior to the
receipt of any such written notice, the Purchase Contract Agent, subject to the provisions of Section 7.01, shall be entitled in all respects to assume that no such facts exist; provided, however, that, if prior to the fifth
Business Day preceding the date upon which by the terms hereof any such moneys may become payable for any purpose, the Purchase Contract Agent shall not have received with respect to such moneys the notice provided for in this sub-section (g), then, anything herein contained to the contrary notwithstanding, the Purchase Contract Agent shall have full power and authority to receive such moneys and/or apply the same to the purpose for which
they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such date; provided, further, no such application shall affect the obligations under the provisions of
Section 5.11(d) through (n) of the Persons receiving such moneys from the Purchase Contract Agent. 
 (h) Anything in this
Agreement, the Units or the Purchase Contracts to the contrary notwithstanding, any deposit of moneys by the Company with the Purchase Contract Agent or any other agent (whether or not in trust) for any payment of the CAP Obligations shall, except
as provided in sub-section (g) above, be subject to the provisions of Section 5.11(d). 

(i) Subject to the payment in full of all Priority Indebtedness of the Company, including the Notes, the Holders of the Units shall be
subrogated to the rights of the holders of such Priority Indebtedness of the Company to receive payments or distributions of assets of the Company applicable to such Priority Indebtedness of the Company until the CAP Obligations shall be paid in
full, and none of the payments or distributions to the holders of such Priority Indebtedness to which the holders of the Units or the Purchase Contract Agent would be entitled except for the provisions of Section 5.11(d) through (n) or of
payments over pursuant to the provisions of Section 5.11(d) through (n) to the holders of such Priority Indebtedness of the Company by the Holders of the Units or the Purchase Contract Agent shall, as among the

  
 80 

 
Company, its creditors other than the holders of such Priority Indebtedness of the Company, and the Holders of such Units, be deemed to be a payment by the Company to or on account of such
Priority Indebtedness of the Company; it being understood that the provisions of Section 5.11(d) through (n) are and are intended solely for the purpose of defining the relative rights of the Holders of the Units, on the one hand, and the
holders of the Priority Indebtedness of the Company, on the other hand. 
 (j) No right of any present or future holders of any Priority
Indebtedness of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such
holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Agreement, the Units or the Purchase Contracts, regardless of any knowledge thereof with which any such holder may have or be otherwise charged. The
holders of Priority Indebtedness of the Company may, at any time or from time to time and in their absolute discretion, change the manner, place or terms of payment, change or extend the time of payment of, or renew or alter, any such Priority
Indebtedness of the Company, or amend or supplement any instrument pursuant to which any such Priority Indebtedness of the Company is issued or by which it may be secured, or release any security therefor, or exercise or refrain from exercising any
other of their rights under the Priority Indebtedness of the Company including, without limitation, the waiver of default thereunder, all without notice to or assent from the Holders of the Units or the Purchase Contract Agent and without affecting
the obligations of the Company, the Purchase Contract Agent or the Holders of the Units under Section 5.11(d) through (n). 
 (k) Each
Holder of a Unit, by his acceptance thereof, authorizes and expressly directs the Purchase Contract Agent on his behalf to take such action as may be necessary or appropriate to effectuate, as between the Holders of such Units and the holders of
Priority Indebtedness of the Company, the subordination provided in Section 5.11(d) through (n). If, in the event of any proceeding or other action relating to the Company referred to in the first sentence of the second paragraph of
Section 5.11(d), a proper claim or proof of debt in the form required in such proceeding or action is not filed by or on behalf of the Holders of the Units with respect to the CAP Obligations prior to fifteen days before the expiration of the
time to file such claim or claims, then the holder or holders of Priority Indebtedness of the Company shall have the right to file and are hereby authorized to file an appropriate claim with respect to the CAP Obligations for and on behalf of the
Holders of such Units. 
 (l) In the event and during the continuation of any default in the payment of principal of or interest on any
Priority Indebtedness of the Company, or in the event that any event of default with respect to any Priority Indebtedness of the Company shall have occurred and be continuing and shall have resulted in such Priority Indebtedness of the Company
becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured, waived or remedied or shall have ceased to exist and such
acceleration shall have been rescinded or annulled or all amounts due on such Priority Indebtedness of the Company are paid in full in cash or other permitted consideration, or in the event any judicial proceeding shall be pending with respect to
any such default in payment or such event or default (unless and until all amounts due on such Priority Indebtedness of the Company are paid in full in cash or other permitted consideration), then no payment or distribution of any kind or character,
whether in cash, properties or securities shall be made by the Company on account of the CAP Obligations. 

  
 81 

 In the event that, notwithstanding the foregoing, the Company shall make any payment to the
Purchase Contract Agent or the Holder of any Unit in respect of the CAP Obligations prohibited by the foregoing provisions of this sub-section (l), and if such fact shall, at or prior to the time of such
payment, have been made known to the Purchase Contract Agent or, as the case may be, such Holder, then and in such event payment shall be paid over and delivered forthwith to the Company. 

(m) The Purchase Contract Agent shall be entitled to all of the rights set forth in Section 5.11(d) through (n) in respect of any
Priority Indebtedness of the Company at any time held by it in its individual capacity and with respect to any amounts owed to the Purchase Contract Agent pursuant to Section 7.07 to the same extent as any other holder of such Priority
Indebtedness of the Company, and nothing in this Agreement, the Units or the Purchase Contracts shall be construed to deprive the Purchase Contract Agent of any of its rights as such holder. 

(n) The failure of the Company to make a payment with respect to the CAP Obligations by reason of any provision in Section 5.11(d)
through (n) shall not be construed as preventing the occurrence of a default under this Agreement, the Units or the Purchase Contracts. 

Section 5.12. 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 (i) which an effective Fundamental Change Early Settlement has occurred, the Fundamental Change Early Settlement Date or
(ii) which 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 a rate equal to 7.5% per annum, compounded on each Contract Adjustment Payment Date to, but excluding, the Contract Adjustment Payment Date on which such deferred Contract
Adjustment Payments are paid (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 sub-section (c) below. 

  
 82 

 (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 one Business Day before the earlier of (i) the Record Date for the 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 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 (other than on the Purchase Contract Settlement Date) or its election to pay any portion of the deferred Contract Adjustment Payments (including Compounded Contract
Adjustment Payments thereon) on a Payment Date prior to the end of an Extension Period, at least one Business Day before the earlier of (i) the Record Date for the 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 Payment Date. 
 (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 its capital 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 ranking on a parity with the CAP Obligations or ranking junior to the CAP Obligations, or (3) make any guarantee payments under any guarantee by the Company of securities of any of its subsidiaries in the case of a guarantee ranking
on a parity with the CAP Obligations or ranking junior to the CAP Obligations; 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 (1) above
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, or in connection with the settlement of stock purchase contracts outstanding on the date that the Contract Adjustment Payment is deferred; 

  
 83 

 (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 the Company’s capital stock in connection with the issuance or exchange of the Company’s capital stock (or of securities
convertible into or exchangeable for shares of the Company’s capital stock) and distributions in connection with the settlement of stock purchase contracts outstanding on the date that the Contract Adjustment Payment is deferred; 

(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, ranking on a parity with the CAP Obligations, 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 

(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 5.13. Special Event Treasury Portfolio. Upon the occurrence of a Special Event Redemption prior to the Purchase Contract
Settlement Date, the Collateral Agent shall cause the Securities Intermediary to Transfer the Notes underlying the Pledged Applicable Ownership in Notes to the Indenture Trustee for payment of the Special Event Redemption Price attributable to such
Notes. The Collateral Agent shall, or in the event the Notes underlying the Pledged Applicable Ownership Interests in Notes are registered in the name of the Purchase Contract Agent, the Purchase Contract Agent shall, direct the Indenture Trustee to
pay the Special Event Redemption Price therefor payable on the Special Event Redemption Date, on or prior to 12:30 p.m., New York City time, by check or wire transfer in immediately available funds at such place and to such account as may be
designated by the Collateral Agent. Upon deposit in the Collateral Account of such Special Event Redemption Price, the Collateral Agent will (x) instruct the Securities Intermediary to apply an amount equal to the sum of the Special Event
Redemption Amounts for all such Notes underlying the Pledged Applicable Ownership in Notes to purchase the Special Event Treasury Portfolio from the dealer identified by the Quotation Agent pursuant to the definition of “Special Event Treasury
Portfolio Purchase Price” (the amount and issue of the Treasury Securities (or principal or interest stripes thereof) to be determined by the Company, who shall provide such information to the Collateral Agent and the Quotation Agent, who will
then 

  
 84 

 
determine, and notify the Collateral Agent of, the Special Event Treasury Portfolio Purchase Price), (y) credit to the Collateral Account the Applicable Ownership Interests in the Special Event
Treasury Portfolio (as specified in clause (B) of such term) and (z) promptly remit the remaining portion of such Special Event Redemption Price attributable to Notes underlying the Pledged Applicable Ownership in the Notes to the Purchase
Contract Agent for payment to the Holders of Corporate Units. Following the occurrence of a Special Event Redemption Date prior to the Purchase Contract Settlement Date, the Applicable Ownership Interests in the Treasury Portfolio (as specified in
clause (B)(i) of such term) will be substituted as Collateral for the Pledged Applicable Ownership Interests in Notes and will be held by the Collateral Agent in accordance with the terms hereof to secure the Obligations of each Holder of Corporate
Units, and the Holders of Corporate Units and the Collateral Agent shall have such security interests, rights and obligations with respect to the Applicable Ownership Interests in the Treasury Portfolio (as defined in clause (B)(i) of such term) as
the Holders of Corporate Units and the Collateral Agent had in respect of the Pledged Applicable Ownership in Notes and the Underlying Notes, subject to the Pledge thereof. Unless the context otherwise requires, any reference in this Agreement or
the Certificates to the Pledged Applicable Ownership Interests in Notes shall thereupon be deemed to be a reference to such Applicable Ownership Interests in the Treasury Portfolio (as defined in clause (B)(i) of such term). 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
(as defined in clause (B)(i) of such term) for the Pledged Applicable Ownership Interests in Notes as Collateral.

enforcement of any interest on any Notes owed pursuant to such Holder’s Applicable Ownership Interests in Notes or Contract Adjustment Payments on or after the respective 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 (including, without limitation, by effecting an Early Settlement or Fundamental Change Early Settlement in

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, but will suffer and permit the execution of every such power as though no
such law had been enacted.

Agent” for the purposes of this Section 7.07 shall include any predecessor Purchase Contract Agent and the Purchase Contract Agent in each of its capacities hereunder and each agent, custodian and other person employed to act hereunder;

Purchase Contract Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case,
(i) the Company by a Board Resolution may remove 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 and all others similarly situated, petition any

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. 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, 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 any court of competent jurisdiction for the appointment of a successor Purchase Contract Agent.

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.

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, 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.

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. Anything contained in this Agreement to the contrary notwithstanding, in no event shall the Purchase Contract Agent or its officers, directors, employees or agents be liable under this Agreement or
the Remarketing Agreement for (i) indirect, special, punitive, or consequential loss or damage of any kind whatsoever, including lost profits, whether or not the likelihood of such loss or damage was known to the Purchase Contract Agent and

civil or military disturbances; terrorist acts; sabotage; epidemics; riots; interruptions, loss or malfunctions of utilities; labor disputes; or acts of civil or military authority or governmental actions, in each case, which delay, restrict or
prohibit the providing of services contemplated by this Agreement; it being understood that the Purchase Contract Agent shall use commercially reasonable efforts which are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under such circumstances.

corporation expressly assumes all of the Company’s responsibilities and liabilities under the Purchase Contracts, the Corporate Units, the Treasury Units, this Agreement, the Remarketing Agreement (if any) and the Indenture by one or more

that is a Plan or that used assets of a Plan to acquire such Book-Entry Interest) constitutes assets of any Plan or (ii) (1) its acquisition, holding and disposition of the Units, shares of Common Stock issuable upon settlement of the
Purchase Contract or Notes, as applicable, will not violate ERISA’s fiduciary standards or other requirements under ERISA, the Code or Similar Laws, or result in a non-exempt prohibited transaction under

ARTICLE 15 
 THE COLLATERAL
AGENT, THE CUSTODIAL AGENT AND 
 THE SECURITIES INTERMEDIARY 

Section 15.01. Appointment, Powers and Immunities. 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 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. The Collateral
Agent, the Custodial Agent and Securities Intermediary shall: 

  
 105 

 (a) have no duties or responsibilities except those expressly set forth in this Agreement
and no implied covenants 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 (to which the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the case may be, is not a party) beyond the specific terms hereof; 

(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, except as expressly required hereby, 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, subject to Section 15.08); 
 (d) not be responsible for any action taken or omitted to be taken by it hereunder or
under any other document or instrument referred to or provided for herein or in connection herewith or therewith, except for its own gross negligence or willful misconduct; and 

(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. 
 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. 

No provision of this Agreement shall require the Collateral Agent, the Custodial Agent or the Securities Intermediary to expend or risk its
own funds or otherwise incur any liability in the performance of any of its duties 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 (i) such direction shall not conflict with the provisions of any law or of this Agreement or involve the
Collateral Agent in personal liability and (ii) the Collateral Agent shall be indemnified to its satisfaction as provided herein. Nothing contained in this Section 15.02 shall 

  
 106 

 
impair the right of the Collateral Agent in its discretion 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. 

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) believed by it in good faith to be genuine 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. As to any discretionary action or matters not expressly provided for by this Agreement, each 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 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), 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. 

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 hereunder, or suffering to exist any state of events, such
matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of bad faith on the part of the Collateral Agent, the Custodial Agent or the Securities Intermediary, be deemed to be conclusively proved and
established by an Officers’ Certificate 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 in reliance thereon. 

(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 that it reasonably believes to be genuine. 

Section 15.05. Merger, Conversion, Consolidation or Succession to Business. Any Person or national association 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 or national association resulting from any merger, conversion or consolidation to which the

  
 107 

 
Collateral Agent, the Custodial Agent or the Securities Intermediary shall be a party, or any Person or national association succeeding to all or substantially all of the corporate trust business
of the Collateral Agent (including the administration of this Agreement), the Custodial Agent or the Securities Intermediary shall be the successor of the Collateral Agent, the Custodial Agent or the Securities Intermediary 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 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 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. 

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 directors,
officers, agents and employees (collectively, the “Pledge Indemnitees”), from and against any and all losses, damages, claims, liabilities, and expenses (including reasonable fees and out of pocket expenses of outside counsel)
(collectively, “Losses” and individually, a “Loss”) that may be imposed on, incurred by, or 

  
 108 

 
asserted against, the Pledge Indemnitees or any of them for following any instructions or other directions upon which any of the Collateral Agent, the Custodial Agent or the Securities
Intermediary is entitled to 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 with respect to the
specific Loss against which indemnification is sought; and 
 (c) in addition to and not in limitation of paragraph (b) of this
Section 15.08, 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 powers and duties under this Agreement, provided the Collateral Agent, the Custodial Agent or the Securities
Intermediary has not acted with gross negligence or engaged in willful misconduct 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, reasonable 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 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. In such
event, 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 reasonably 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 or an indemnity reasonably satisfactory to it sufficient to hold it harmless from and against any and all loss, liability or reasonable
out-of-pocket expense which it may incur by reason of its acting. 

  
 109 

 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 personal liability. 
 Section 15.10. Resignation of Collateral Agent, the Custodial Agent and the
Securities Intermediary. 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; 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 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 Holders of a majority of the Units. 
 The
Purchase Contract Agent shall promptly notify the Company upon the transmission of notice as contemplated by clause (iii) of Section 15.10 and any removal of the Collateral Agent, the Custodial Agent or the Securities Intermediary pursuant
to clause (iii) of this Section 15.10. Upon any such resignation or removal under this Section 15.10, the Company shall have the right to appoint a successor Collateral Agent, Custodial Agent or Securities Intermediary, as the case
may be, which shall not be an Affiliate of the Purchase Contract Agent. If no successor Collateral Agent, Custodial Agent or Securities Intermediary shall have been so appointed and shall have accepted such appointment within 45 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 or a national banking association (which has an office or agency in the continental United States of America) 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 

  
 110 

 
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 reliance upon the advice of, such agents or advisors selected in good faith. The appointment of agents pursuant to
this Section 15.11 shall be subject to prior written consent of the Company, which consent shall not be unreasonably withheld. 

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, 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. 
 Section 15.14. Expenses, Etc. The Company agrees to
reimburse the Collateral Agent, the Custodial Agent and the Securities Intermediary for: 
 (a) all reasonable costs, fees and out-of-pocket 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 (excluding taxes that are based on or measured by income
in whole or in part (including franchise taxes)) and (ii) any modification, supplement or waiver of any of the terms of this Agreement; 

  
 111 

 (b) all reasonable costs, fees and out-of-pocket 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; 

(c) all transfer, stamp, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect
of this Agreement 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; 

(d) all reasonable fees and out-of-pocket expenses of any
agent or advisor appointed by the Collateral Agent and consented to by the Company under Section 15.11; and 
 (e) any other out-of-pocket costs and expenses (excluding taxes) reasonably incurred by the Collateral Agent, the Custodial Agent and the Securities Intermediary in connection with the
performance of their duties hereunder. 
 Section 15.15. Force Majeure. In no event shall any of the Collateral Agent, Custodial
Agent and Securities Intermediary be responsible or liable for any failure or delay in the performance of its obligations under this Agreement arising out of or caused by circumstances beyond its control, including, without limitation, acts of God;
earthquake; fires; floods; wars; civil or military disturbances; terrorist acts; sabotage; epidemics; riots; interruptions, loss or malfunctions of utilities; or acts of civil or military authority or governmental actions, in each case, which delay,
restrict or prohibit the providing of services contemplated by this Agreement; it being understood that the Collateral Agent, Custodial Agent and Securities Intermediary shall use commercially reasonable efforts which are consistent with accepted
practices in the banking industry to resume performance as soon as practicable under such circumstances. 
 ARTICLE 16 

MISCELLANEOUS 

Section 16.01. 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, the Purchase Contract 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. 

  
 112

Event, the Company shall deliver written notice to the Purchase Contract Agent, the Collateral Agent and the Securities Intermediary within a reasonable amount of time and to the extent permitted by law.

information that identifies each person establishing a relationship or opening an account. The parties to this Agreement agree that they will provide to the Agent such information as it may request, from time to time, in order for the Agent to
satisfy the requirements of the USA PATRIOT Act, including but not limited to the name, address, tax identification number and other information that will allow it to identify the individual or entity who is establishing the relationship or opening
the account and may also ask for formation documents such as articles of incorporation or other identifying documents to be provided.

All capitalized terms used herein 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 (as defined below), 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 Notes or the Applicable Ownership Interest in the
Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of Applicable Ownership Interest in the Treasury Portfolio, as the case may be), as the case may be, constituting part of each Corporate Unit evidenced hereby have
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 of interest on the Pledged Applicable Ownership Interests in Notes or distributions with respect to the Applicable Ownership
Interests in the Treasury Portfolio (as specified in clause (A)(ii) o (B)(ii) of the definition of Applicable Ownership Interests in the Treasury Portfolio, as the case may be), 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. Interest on the Notes underlying the Applicable Ownership Interests in Notes or 

  
 A-2 

 
distributions on the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(ii) or (B)(ii) of the definition of Applicable Ownership Interests in the Treasury
Portfolio, as the case may be), as the case may be, forming part of the Corporate Units evidenced hereby, which are payable on each Payment Date (or, in the case of distributions on the Applicable Ownership Interests in the Treasury Portfolio (as
specified in clause (A)(ii) or (B)(ii) of the definition of Applicable Ownership Interests in the Treasury Portfolio, as the case may be), which is payable on the maturity date thereof), shall, subject to receipt thereof by the Purchase
Contract Agent, be paid to the Person in whose name this Corporate Units Certificate (or a Predecessor Corporate Units Certificate) is registered at the close of business on the Record Date for the relevant Payment Date. 

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 shares of Common Stock, 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 Notes underlying the Pledged Applicable Ownership Interests in Notes
equal to the principal amount thereof or the proceeds of the Pledged Applicable Ownership Interests in the Treasury Portfolio, as the case may be, pledged to secure the Holder’s Obligations under such Purchase Contract.

least five Business Days prior to the relevant Payment Date, by wire transfer to such account. All payments with respect to Global Certificates will be made by wire transfer of immediately available funds to the Depositary. 

Each Purchase Contract evidenced hereby obligates each Holder and Beneficial Owner to agree, for U.S. federal, state and local income tax
purposes (unless otherwise required by any taxing authority) (i) to treat each Beneficial Owner of a Corporate Unit as the owner, separately, of each of the applicable Purchase Contract and the applicable interests in the Collateral, including
the Notes underlying the Applicable Ownership Interests in Notes or the Applicable Ownership Interests in the Treasury Portfolio, as the case may be, (ii) to treat the Notes as indebtedness, (iii) to allocate, as of the date hereof, 100%
of the purchase price for a Corporate Unit to the Applicable Ownership Interests in Notes and 0% to each Purchase Contract, which will establish each Beneficial Owner’s initial tax basis in each Purchase Contract as $0 and each Beneficial
Owner’s initial tax basis in each Applicable Ownership Interest in Notes as $50, and (iv) in all events, not to take any position for U.S. federal, state or local income tax purposes that is inconsistent with or contrary to the above
covenants.

 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 6.75% per year of the Stated Amount, computed on the basis of a 360-day year
consisting of twelve 30-day months. Such Contract Adjustment Payments shall be payable 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 Priority Indebtedness, including the Notes. 
 If the book-entry
system for the Corporate Units has been terminated, the Contract Adjustment Payments will be payable by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register or, if such
Person so requests and designates an account in writing to the Purchase Contract Agent at least five Business Days prior to the relevant Payment Date, by wire transfer to such account. 

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 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 the Purchase Contract and Pledge Agreement, dated as of February 16, 2021 (as may
be supplemented from time to time, the “Purchase Contract and Pledge Agreement”), among the Company and U.S. Bank National Association, as Purchase Contract Agent and
attorney-in-fact for the Holders of Corporate Units and Treasury Units from time to time, as Collateral Agent, as Custodial Agent, and as Securities Intermediary, 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 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. The Settlement Rate is subject to adjustment as described in the Purchase Contract and Pledge Agreement. 

No fractional shares of Common Stock will be issued upon settlement of any Purchase Contracts, as provided in Section 5.09 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 shares of Common Stock equal to the Minimum Settlement Rate, in the case of an Early Settlement,
or the Settlement Rate plus the applicable number of Make-Whole Shares (determined, in each case, as set forth in the Purchase Contract and Pledge Agreement), in the case of a Fundamental Change Early Settlement. 

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 purchased pursuant to each Purchase Contract evidenced hereby by effecting a Cash Settlement, an Early Settlement, a Fundamental Change Early Settlement, from
the proceeds of the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of Applicable Ownership Interest in the Treasury Portfolio, as the case may be), from the proceeds of a
Final Remarketing of the Notes underlying the Pledged Applicable Ownership Interests in Notes or from the exercise of a Holder’s Put Right. Unless a Termination Event has occurred, a Holder of Corporate Units who (1) does not make an
effective Cash Settlement in the manner and by the time provided in Section 5.02(b)(ix) or 5.03(a) of the Purchase Contract and Pledge Agreement, (2) does not, in the manner and at the times provided in the Purchase Contract and Pledge
Agreement, make an effective Early Settlement and (3) does not, in the manner and at the times provided in the Purchase Contract and Pledge Agreement, make an effective Fundamental Change Early Settlement, shall pay the Purchase Price, as
described in the Purchase Contract and Pledge Agreement, for the shares of Common Stock to be delivered under the related Purchase Contract (1) in the case of a 

  
 A-6 

 
Successful Final Remarketing, from the proceeds of the sale of the Notes underlying the Pledged Applicable Ownership Interests in Notes held by the Collateral Agent in the Final Remarketing,
(2) in the case of a Successful Optional Remarketing or a Special Event Redemption, from the proceeds at maturity of the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or B(i) of the definition of
Applicable Ownership Interest in the Treasury Portfolio, as the case may be) or (3) in the case of a Failed Remarketing, from the proceeds of the exercise of a Holder’s Put Right, as described below. 

As provided in the Purchase Contract and Pledge Agreement, upon the occurrence of a Failed Final Remarketing, as of the Purchase Contract
Settlement Date, each Holder of any Pledged Applicable Ownership Interests in Notes, unless such Holder has elected Cash Settlement and delivered cash in accordance with Section 5.02(b)(ix) of the Purchase Contract and Pledge Agreement, shall
be deemed to have exercised such Holder’s Put Right with respect to the Notes underlying such Applicable Ownership Interests in Notes and to have elected to apply the Proceeds of the Put Price therefor against 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 Holders’ Obligations under such Purchase Contracts. 

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, as described in the Purchase Contract and Pledge Agreement, for the shares of Common Stock to be purchased thereunder in the manner set forth in the Purchase
Contract and Pledge Agreement. 
 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, shall immediately and automatically terminate, without the necessity of any notice or action by any
Holder, the Purchase Contract Agent or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. 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 Notes underlying the Pledged
Applicable Ownership Interests in Notes or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of such term, as the case may be) forming a part of each Corporate Unit, and all
other Collateral, from the Pledge. A Corporate Unit shall thereafter represent the right to receive the Notes underlying the Applicable Ownership Interest in the Notes or the Applicable Ownership Interests in the Treasury Portfolio forming a part of
such Corporate Units 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 shall exercise the voting and any other consensual rights pertaining to the Notes underlying the Pledged Applicable Ownership Interests in Notes to the extent instructed in writing by the Holders.
Upon receipt of notice of any meeting at which holders of Notes are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of Notes, the Purchase Contract Agent shall, as soon as practicable thereafter, mail, first
class, postage prepaid, to the Corporate Units Holders the notice required by the Purchase Contract and Pledge Agreement. 

  
 A-7 

 Subject to the provisions of the Purchase Contract and Pledge Agreement, upon the occurrence
of a Successful Optional Remarketing and receipt in the Collateral Account of the proceeds thereof, the Collateral Agent shall instruct the Securities Intermediary to apply an amount equal to the Remarketing Treasury Portfolio Purchase Price to
purchase the Treasury Portfolio. 
 Following the occurrence of a Successful Optional Remarketing or a Special Event Redemption, the Holders
of Corporate Units and the Collateral Agent shall have such security interests, rights and obligations with respect to the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of
such term, as the case may be) as the Holder of Corporate Units and the Collateral Agent had in respect of Applicable Ownership Interests in Notes and the underlying Notes, subject to the Pledge thereof as provided in the Purchase Contract and
Pledge Agreement and any reference herein to the Notes or Applicable Ownership Interests in Notes shall be deemed to be a reference to the Treasury Portfolio or the Applicable Ownership Interests in the Treasury Portfolio, as the case may be. 

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
with an aggregate principal amount at maturity equal to the aggregate principal amount of Notes underlying the Applicable Ownership Interests in Notes, thereby creating Treasury Units, shall be responsible for any 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
Applicable Ownership Interest in Notes, or Applicable Ownership Interest in the Treasury Portfolio, as the case may be, and the Purchase Contract constituting such Corporate Units may be acquired, and may be transferred and exchanged, only as a
Corporate Unit. 
 Subject to, and in compliance with, the terms and conditions 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 obligation under the Purchase Contract shall be referred to as a
“Treasury Unit.” Subject to certain exceptions in the Purchase Contract and Pledge Agreement, a Holder may make such Collateral Substitution only in integral multiples of 20 Corporate Units for 20 Treasury 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 as provided in the Purchase Contract and Pledge Agreement in integral multiples of 20 Corporate Units, or if Applicable Ownership
Interests in the Treasury Portfolio have replaced the Applicable Ownership Interests in Notes as a component of the Corporate Units, in such integral multiples of Corporate Units as may be determined the Company or, in the case of a Remarketing, by
the Remarketing Agent upon a successful Remarketing. 

  
 A-8 

 Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Notes
underlying the Pledged Applicable Ownership Interests in Notes or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of such term, as the case may be) underlying such Units
shall be released from the Pledge as provided in the Purchase Contract and Pledge Agreement and the Holder shall be entitled to receive a number of shares of Common Stock equal to the Minimum Settlement Rate for each Purchase Contract as to which
Early Settlement is effected. 
 Upon the occurrence of a Fundamental Change, a Holder of Corporate Units may effect Fundamental Change
Early Settlement of the Purchase Contracts underlying such Corporate Units pursuant to the terms of the Purchase Contract and Pledge Agreement in integral multiples of 20 Corporate Units, or if the Applicable Ownership Interests in the Treasury
Portfolio have replaced the Applicable Ownership Interests in Notes as a component of the Corporate Units, in such integral multiples of Corporate Units as may be determined the Company or, in the case of a Remarketing, by the Remarketing Agent upon
a successful Remarketing. Upon Fundamental Change Early Settlement of Purchase Contracts by a Holder of the related Corporate Units, the Notes underlying the Pledged Applicable Ownership Interests in Notes or the Applicable Ownership Interests in
the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of such term, as the case may be) underlying such Corporate Units shall be released from the Pledge as provided in the Purchase Contract and Pledge Agreement and
the Holder shall be entitled to receive a number of shares of Common Stock or other consideration specified in the Purchase Contract and Pledge Agreement on account of each Purchase Contract that forms a part of a Corporate Unit as to which
Fundamental Change Early Settlement is effected equal to the sum of the applicable Settlement Rate and the applicable number of Make-Whole Shares (determined, in each case, as set forth 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 and the Purchase Contract and Pledge Agreement on its behalf and in its name as its attorney-in-fact; agrees to be bound by the terms and provisions of the Corporate Unit evidenced hereby (including, but not limited to, the terms and provisions of the
Purchase Contract forming part of such Unit, and the Purchase Contract and Pledge Agreement) for so long as it remains a Holder of such Unit; consents to, and agrees to be bound by, the Pledge of the Applicable Ownership Interests in Notes and the
underlying Notes or the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of Applicable Ownership Interest in the Treasury Portfolio, as the case may be), as the case may be,
underlying this Corporate Units Certificate pursuant to the Purchase Contract and Pledge Agreement; and expressly withholds any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise of the Purchase Contract forming
part of the Corporate Unit evidenced hereby by the Company or its trustee, receiver, liquidator or any person or entity 

  
 A-9 

 
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.
The Holder further covenants and agrees that, to the extent and in the manner provided in the Purchase Contract and Pledge Agreement, any payments with respect to the Notes underlying the Pledged Applicable Ownership Interests in Notes (other than
interest payments thereon) or the Proceeds of the Applicable Ownership Interests in the Treasury Portfolio (as specified in clause (A)(i) or (B)(i) of the definition of Applicable Ownership Interest in the Treasury Portfolio, as the case may
be), as the case may be, on the Purchase Contract Settlement Date in an amount equal to the aggregate Purchase Price, as described in the Purchase Contract and Pledge Agreement, 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. 
 Subject to certain
exceptions, the provisions of the Purchase Contract and Pledge Agreement may be amended with the consent of the Holders of not less than a majority of the Outstanding Units. 

The Corporate Units and Purchase Contracts shall be governed by, and construed in accordance with, the laws of the State of New York (without
regard to conflicts of laws principles thereof). 
 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 and 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 (subject to the applicable record date) any payment or distribution with respect to the Notes underlying the Applicable Ownership Interests in Notes, the Applicable Ownership Interests in the Treasury Portfolio (as specified in
clause (A)(ii) or (B)(ii) of the definition thereof, as the case may be) or payment of Contract Adjustment Payments and performance of the Purchase Contracts and for all other purposes whatsoever in connection with the Corporate Units, whether
or not such payment, distribution, or performance shall be overdue and notwithstanding any notice to the contrary, and neither the Company or the Purchase Contract Agent, nor any agent of the Company or the Purchase Contract Agent, shall be affected
by notice to the contrary. A copy of the Purchase Contract and Pledge Agreement is available for inspection at the offices of the Purchase Contract Agent.

Treasury Units 
 This
Treasury Units Certificate certifies that [Cede & Co.] 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, shall not exceed [[3,200,000]Units (as
increased by the number of Units, if any, with respect to which the underwriters in the Units offering exercise their over-allotment option)]]. Each Treasury Unit consists of (i) a 1/20th or 5% undivided beneficial ownership interest in a
Treasury Security having a principal amount at maturity equal to $1,000, 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 pursuant to which (A) the Holder will agree to purchase from the Company, and the Company will agree to sell to the Holder, on the Purchase Contract Settlement Date (unless a Termination Event, an
Early Settlement or a Fundamental Change Early Settlement has occurred), for the Stated Amount in cash, a number of shares of Common Stock equal to the Settlement Rate, subject to anti-dilution adjustments and (B) the Company will pay the
Holder quarterly Contract Adjustment Payments, subject to the Company’s right to defer such Contract Adjustment Payments. 
 All
capitalized terms used herein 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 (as defined below), the provisions of the Purchase Contract and Pledge Agreement shall govern and control. 
 Pursuant to
the Purchase Contract and Pledge Agreement, the Treasury Securities underlying each Treasury Unit evidenced hereby have 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. 
 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 shares of Common Stock 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 the proceeds from the Treasury Securities at maturity pledged to
secure the Holder’s Obligations under such Purchase Contract. 

  
 B-2 

 Each Purchase Contract evidenced hereby obligates each Holder and Beneficial Owner to agree,
for U.S. federal, state and local income tax purposes (unless otherwise required by any taxing authority), to treat each Beneficial Owner of a Treasury Unit as the owner, separately of each of the applicable Purchase Contract and the applicable
interests in the Treasury Securities. 
 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 6.75% per year of the Stated Amount, computed on the basis of a 360-day year
consisting of twelve 30-day months. Such Contract Adjustment Payments shall be payable 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 Priority Indebtedness, including the Notes. 
 If the book-entry
system for the Treasury Units has been terminated, the Contract Adjustment Payments will be payable by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register or, if such Person
so requests and designates an account in writing to the Purchase Contract Agent at least five Business Days prior to the relevant Payment Date, by wire transfer to such account. 

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 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 February 16, 2021 (as may be
supplemented from time to time, the “Purchase Contract and Pledge Agreement”) among the Company and U.S. Bank National Association, as Purchase Contract Agent and
attorney-in-fact for the Holders of Corporate Units and Treasury Units from time to time, as Collateral Agent, as Custodial Agent and as Securities Intermediary, 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 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 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. The Settlement Rate is subject to adjustment as described in the Purchase Contract and Pledge Agreement. 

No fractional shares of Common Stock will be issued upon settlement of any Purchase Contracts, as provided in Section 5.09 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 shares of Common Stock equal to the Minimum Settlement Rate, in the case of an Early Settlement,
or the Settlement Rate plus the applicable number of Make-Whole Shares (determined, in each case, as set forth in the Purchase Contract and Pledge Agreement), in the case of a Fundamental Change Early Settlement. 

In accordance with the terms of the Purchase Contract and Pledge Agreement, the Holder of this Treasury Unit Certificate shall pay the
Purchase Price for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby either 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 Pledged Treasury Securities underlying such Holder’s Treasury Unit equal to the Purchase Price for such Purchase Contract to the purchase of the Common Stock. A Holder of Treasury Units who does not, in the manner
and at the times provided in the Purchase Contract and Pledge Agreement, make an effective Early Settlement or Fundamental Change Early Settlement, shall pay the Purchase Price, as described in the Purchase Contract and Pledge Agreement, for the
shares of Common Stock to be issued under the related Purchase Contract from the proceeds of the Pledged Treasury Securities. 
 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, as described in the Purchase
Contract and Pledge Agreement, for the shares of Common Stock to be purchased thereunder in the manner set forth in the Purchase Contract and Pledge Agreement. 

  
 B-5 

 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, shall immediately and automatically terminate, without the necessity of any notice or action
by any Holder, the Purchase Contract Agent or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall give written notice to the
Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register. Upon the occurrence of a Termination Event, the Collateral Agent shall release the Treasury Securities underlying each
Treasury Unit, and all other Collateral, 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 Notes for
Treasury Securities, thereby recreating Corporate Units, shall be responsible for any 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 interest in the Treasury Security and the Purchase Contract constituting such Treasury Unit may be acquired, and may be transferred and
exchanged, only as a Treasury Unit. 
 Subject to, and in compliance with, the terms and conditions set forth in the Purchase Contract and
Pledge Agreement, the Holder of Treasury Units may effect a Collateral Substitution. From and after such substitution, each Unit for which Pledged Applicable Ownership Interests in Notes secure the Holder’s obligation under the Purchase
Contract shall be referred to as a “Corporate Unit.” Subject to certain exceptions described in the Purchase Contract and Pledge Agreement, a Holder may make such Collateral Substitution only in integral multiples of 20 Treasury Units for
20 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 as provided in the Purchase Contract and Pledge Agreement in integral multiples of 20 Treasury Units.

 Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Pledged Treasury Securities underlying such Units shall
be released from the Pledge as provided in the Purchase Contract and Pledge Agreement and the Holder shall be entitled to receive a number of shares of Common Stock equal to the Minimum Settlement Rate for each Purchase Contract as to which Early
Settlement is effected. 

  
 B-6 

 Upon the occurrence of a Fundamental Change, a Holder of Treasury Units may effect
Fundamental Change Early Settlement of the Purchase Contracts underlying such Treasury Units pursuant to the terms of the Purchase Contract and Pledge Agreement in integral multiples of 20 Treasury Units. Upon Fundamental Change Early Settlement of
Purchase Contracts by a Holder of the related Treasury Units, the Pledged Treasury Securities underlying such Treasury Units shall be released from the Pledge as provided in the Purchase Contract and Pledge Agreement and the Holder shall be entitled
to receive a number of shares of Common Stock or other consideration specified in the Purchase Contract and Pledge Agreement on account of each Purchase Contract that forms a part of a Treasury Unit as to which Fundamental Change Early Settlement is
effected equal to the sum of the Settlement Rate and the applicable number of Make-Whole Shares (determined, in each case, as set forth 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 and the Purchase Contract and Pledge Agreement on its behalf and in its name as its attorney-in-fact; agrees to be bound by the terms and provisions of the Treasury Unit evidenced hereby (including, but not limited to, the terms and provisions of the Purchase
Contract forming part of such Unit, and the Purchase Contract and Pledge Agreement) for so long as it remains a Holder of such Unit; consents to, and agrees to be bound by, the Pledge of the Pledged Treasury Securities underlying this Treasury Units
Certificate pursuant to the Purchase Contract and Pledge Agreement; and expressly withholds any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise of the Purchase Contract forming part of the Treasury Unit evidenced
hereby by the Company or its trustee, receiver, liquidator or any 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. The Holder further covenants and agrees, that, to the extent and in the manner provided in the Purchase Contract and Pledge Agreement, payments in respect to the aggregate principal amount at maturity of the Pledged
Treasury Securities on the Purchase Contract Settlement Date equal to the aggregate Purchase Price, as described in the Purchase Contract and Pledge Agreement, 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. 
 Subject to certain exceptions, the provisions of the
Purchase Contract and Pledge Agreement may be amended with the consent of the Holders of not less than a majority of the Outstanding Units. 

  
 B-7 

 The Purchase Contracts shall be governed by, and construed in accordance with, the laws of
the State of New York (without regard to conflicts of laws principles thereof). 
 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 and 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 (subject to the applicable record date) any payment of Contract Adjustment Payments and performance of the Purchase Contracts and for all other purposes whatsoever in connection with the Treasury Units, whether or
not such payment, distribution, or performance shall be overdue and notwithstanding any notice to the contrary, and neither the Company or the Purchase Contract Agent, nor any agent of the Company or the Purchase Contract Agent, shall be affected by
notice to the contrary. A copy of the Purchase Contract and Pledge Agreement is available for inspection at the offices of the Purchase Contract Agent.

to at least the applicable Remarketing Price and that in the reasonable discretion of the Remarketing Agent will enable it to remarket all of the Remarketed Notes at no less than the applicable Remarketing Price in such Remarketing; provided that
such Reset Rate shall not exceed the maximum interest rate permitted by applicable law. 
 (e) If, by 4:00 p.m., New York City time, on the
applicable Remarketing Date, (i) the Remarketing Agent is unable to Remarket all of the Remarketed Notes, at a price not less than the applicable Remarketing Price pursuant to the terms and conditions hereof or (ii) the Remarketing did not
occur on such Remarketing Date because one of the conditions set forth in Section 6 hereof was not satisfied, the Remarketing Agent shall advise by telephone (and promptly deliver a notice in writing thereafter to) the Depository, the Purchase
Contract Agent, the Collateral Agent and the Company. Whether or not there has been a Failed Remarketing will be determined in the sole reasonable discretion of the Remarketing Agent. In the event of a Failed Remarketing, the applicable interest
rate on the Notes will not be reset and will continue to be the Coupon Rate set forth in the Supplemental Indenture. 
 (f) In the event of
a Successful Remarketing, by approximately 4:30 p.m., New York City time, on the applicable Remarketing Date, the Remarketing Agent shall advise, by telephone: 

(i) the Depository, the Purchase Contract Agent, the Trustee, the Collateral Agent, the Custodial Agent and the Company (and
promptly deliver a notice in writing to such Persons thereafter) of the Reset Rate with respect to the Notes and the aggregate principal amount of Remarketed Notes sold in such Remarketing; 

  
 P-5 

 (ii) each purchaser (or the Depository Participant thereof) of Remarketed
Notes of the Reset Rate and the aggregate principal amount of Remarketed Notes such purchaser is to purchase; 
 (iii) each
such purchaser (if other than a Depository Participant) to give instructions to its Depository Participant to pay the purchase price on the Remarketing Settlement Date in same day funds against delivery of the Remarketed Notes purchased through the
facilities of the Depository; and 
 (iv) each such purchaser (or Depository Participant thereof) that the Remarketed Notes
will not be delivered until the Remarketing Settlement Date and (if applicable) that if such purchaser wishes to trade the Remarketed Notes that it has purchased prior to the second Business Day preceding the Remarketing Settlement Date, such
purchaser will have to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. 
 The
Remarketing Agent shall also, if required by the Securities Act, deliver, in conformity with the requirements of the Securities Act, to each purchaser a Prospectus in connection with the Remarketing. 

(g) The proceeds from a Successful Remarketing (i) with respect to the Notes underlying the Applicable Ownership Interests in Notes that
are components of the Corporate Units and (ii) with respect to the Separate Notes, in each case, shall be applied in accordance with Section 5.02 of the Purchase Contract and Pledge Agreement. 

(h) It is understood and agreed that the Remarketing Agent shall not have any obligation whatsoever to purchase any Remarketed Notes, whether
in the Remarketing or otherwise, and shall in no way be obligated to provide funds to make payment upon surrender of Remarketed Notes for Remarketing or to otherwise expend or risk its own funds or incur or to be exposed to financial liability in
the performance of its duties under this Agreement. Neither the Company nor the Remarketing Agent shall be obligated in any case to provide funds to make payment upon surrender of the Remarketed Notes for Remarketing.

interest, mortgage, pledge, lien, claim, encumbrance or equitable right. 
 (c) The execution, delivery and performance of this Agreement
and the Indenture and compliance by the Company with its obligations under this Agreement and the Indenture do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of or

lease or any other agreement or instrument, to which the Company or any subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any subsidiary is subject (except for such
conflicts, breaches or defaults or liens, charges or encumbrances that would not have a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or bylaws of the Company or any subsidiary, or any
applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any subsidiary or any of their respective properties,
assets or operations.

company” which is required to be registered under the Investment Company Act of 1940, as amended. 
 (e) If the Registration Covenants

thereto, each Registration Statement relating to the Remarketed Notes conformed in all material respects with the requirements of the Securities Act, the Trust Indenture Act, and the rules and regulations of the Commission (the “Rules and
Regulations”), and did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and, as of the time immediately prior to
the time of the first sale of Remarketed Notes to investors during the Applicable Remarketing Period (the “Applicable Time”) and each time each Registration Statement is amended, each Registration Statement as then amended, and,
each time 

  
 P-7 

 
the Prospectus is amended, on the date of each supplement thereto, reflect the terms of the Remarketed Notes and the terms of offering thereof, and any other material reflected in such
supplement, in the form in which it is first filed with the Commission pursuant to Rule 424 of the Securities Act (the “Supplement”), the Prospectus as then amended or supplemented, will conform in all material respects with the
requirements of the Securities Act, the Trust Indenture Act and the Rules and Regulations and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading, except that none of the foregoing applies to statements in or omissions from any such documents based upon information furnished to the Company in
writing by the Remarketing Agent, directly or indirectly, expressly for use therein, or to the part of the Registration Statement that constitutes the Indenture Trustee’s Statement of Eligibility under the Trust Indenture Act. The foregoing
representations and warranties are given on the basis that any statement contained in any document incorporated by reference into the Registration Statement shall be deemed not to be contained in the Registration Statement if the statement has been
modified or superseded by any statement in a subsequently filed document incorporated by reference into the Registration Statement or in the Registration Statement or in any amendment or supplement thereto. 

(g) If the Registration Covenants are applicable, as of the Applicable Time, the Disclosure Package, when taken together as a whole, does not
contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The foregoing sentence does not apply
to statements in or omissions from the Disclosure Package based upon information furnished to the Company by the Remarketing Agent, directly or indirectly, expressly for use therein or to the part of the Registration Statement that constitutes the
Indenture Trustee’s Statement of Eligibility under the Trust Indenture Act and is given on the basis that any statement contained in any document incorporated by reference into the Disclosure Package shall be deemed not to be contained in the
Disclosure Package if the statement has been modified or superseded by any statement in a subsequently filed document incorporated by reference into the Disclosure Package or in the Registration Statement or in any amendment or supplement thereto.

 (h) If the Registration Covenants are applicable, each Issuer Free Writing Prospectus does not include any information that conflicts
with the information contained in the Registration Statement, including any document incorporated therein and any Supplement deemed to be a part thereof, that has not been superseded or modified (including, if applicable, pursuant to any such Issuer
Free Writing Prospectus). 
 (i) If the Registration Covenants are applicable and the Registration Statement is an “automatic shelf
registration statement” on Form S-3ASR, the Company has not been and is not an “ineligible issuer” as defined in Rule 405 under the Securities Act at the times specified in the Securities Act in
connection with the Remarketing. 
 (j) If the Registration Covenants are applicable and the Registration Statement is an “automatic
shelf registration statement” on Form S-3ASR, (i) at each time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) made
any offer relating to the Remarketed Notes in reliance on the exemption of Rule 163 under the Securities Act and (ii) at each Representation Date, the Company is a “well- known seasoned issuer” as defined in Rule 405 under the
Securities Act, and the Company has not received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the use of the automatic shelf registration form. 

  
 P-8 

 (k) No default or event of default, and no event that with the passage of time or the giving
of notice or both would become an event of default, has occurred and is continuing, under any of the Transaction Documents. 
 (l) In
connection with any Remarketing conducted in accordance with Rule 144A of the Securities Act or any other exemption from registration thereunder, any preliminary offering memorandum or any communication, document or material relating to the Notes
that would, if the Remarketing were conducted as a public offering pursuant to a registration statement filed under the Securities Act, constitute a “free writing prospectus,” as defined in Rule 405 under the Securities Act (including the
documents incorporated or deemed incorporated by reference in any such document or materials) (the “Private Placement Marketing Materials”), and any further amendments or supplements to the Private Placement Remarketing Materials do
not and will not as of their respective dates of distribution to investors (and as amended or supplemented, as of such date), contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not misleading. The foregoing sentence does not apply to statements in or omissions from the Private Placement Marketing Materials based upon and in conformity with written
information furnished to the Company by the Remarketing Agent, directly or indirectly, expressly for use therein. 
 Section 4. FEES. 

In the event of a Successful Remarketing of the Remarketed Notes, the Company shall pay the Remarketing Agent a remarketing fee to be agreed upon in writing
by the Company and the Remarketing Agent prior to any such Remarketing (the “Remarketing Fee”). 
 Section 5. COVENANTS OF THE
ISSUER. 
 The Company covenants and agrees as follows: 

(a) If and to the extent the offering of the Remarketed Notes in the Remarketing is required (in the view of counsel for the Company) to be
registered under the Securities Act as in effect at the time of the Remarketing, the Company shall (Section 5(a) of this Agreement, the “Registration Covenants”): 

(i) if the Registration Statement is an “automatic shelf registration statement” on Form S-3ASR and if, at any time prior to the Remarketing Settlement Date, the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf
registration statement form, then (A) promptly notify the Remarketing Agent, (B) promptly file a new registration statement or post-effective amendment on the proper form relating to the Remarketed Notes, in a form satisfactory to the
Remarketing Agent, (C) use its best efforts to cause such registration statement or post-effective amendment to be declared effective and (D) promptly notify the Remarketing Agent of such effectiveness; take all other action necessary or
appropriate to 

  
 P-9

has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be; 

(ii) pay the required Commission filing fees relating to the Remarketed Notes within the time required by Rule 456(b)(1) of the
Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act; 

(iii) prepare the Prospectus, file any such Prospectus pursuant to the Securities Act within the period required by the
Securities Act and the rules and regulations thereunder and use commercially reasonable efforts to cause, if not already effective, the Registration Statement to be declared effective by the Commission prior to the applicable Remarketing Date (it
being understood that, for so long as there is a material business transaction or development that has not yet been publicly disclosed, other than in connection with an Optional Remarketing, the Company will not be required to file such Registration
Statement or provide such a Prospectus until the Company has publicly disclosed such transaction or development); 
 (iv)
file with the Commission any amendment to the Registration Statement or the Prospectus or any supplement to the Prospectus that may, in the reasonable judgment of the Company, be required by the Securities Act or requested by the Commission; 

(v) advise the Remarketing Agent promptly after it receives notice thereof, of the time when, (A) prior to the Remarketing
Settlement Date, any amendment to the Registration Statement has been filed or becomes effective or, (B) before, on or after the Remarketing Settlement Date, any supplement to the Prospectus or any amended Prospectus has been filed, and in each
such case excluding documents filed under the Exchange Act incorporated by reference and in each case of (A) and (B) furnish the Remarketing Agent with copies of such notice; 

(vi) file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the
Commission pursuant to Section 13(a) or (c), 14 or 15(d) of the Exchange Act subsequent to the Commencement Date and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Remarketed Notes
(including in circumstances where such requirement may be satisfied pursuant to Rule 172), and during such same period to advise the Remarketing Agent, promptly after it receives notice thereof, (A) of the time when any amendment to any
Registration Statement has become effective or any supplement to any Prospectus or any amended Prospectus has been filed, (B) of the issuance by the Commission of any stop order or of any order preventing or suspending the use of the
Prospectus, (C) of the suspension of the qualification of the Remarketed Notes for offering or sale in any jurisdiction, (D) of the initiation or threatening of any proceeding or examination for any such purpose or pursuant to
Section 8A of the Securities Act, or (E) of any request by the Commission for the amending or supplementing of any Registration Statement or Prospectus or for additional information; and in the event of the issuance of any such stop order
or of any such order preventing or suspending the use of any Prospectus or suspending any such qualification, use promptly its best efforts to obtain its withdrawal; 

  
 P-10 

 (vii) if reasonably requested by the Remarketing Agent, prepare a final term
sheet for the Remarketed Notes, containing solely a description of the Remarketed Notes, in a form agreed to with the Remarketing Agent, and file such final term sheet and all other Issuer Free Writing Prospectuses required to be filed by the
Company with the Commission pursuant to Rule 433(d) under the Securities Act within the time required by such Rule; 
 (viii)
furnish promptly to the Remarketing Agent such copies of the following documents in such quantities as the Remarketing Agent shall reasonably request: (a) conformed copies of the Registration Statement as originally filed with the Commission
and each amendment thereto (in each case excluding exhibits); (b) the Preliminary Prospectus and any amendment or supplement thereto; (c) the Prospectus and any amendment or supplement thereto; (d) any Issuer Free Writing Prospectus and
any amendment or supplement thereto, and (e) any document incorporated by reference in the Prospectus (excluding exhibits thereto); and, if at any time when delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a)
under the Securities Act) is required in connection with the Remarketing, any event or development shall have occurred as a result of which (1) the Prospectus as then amended or supplemented would include any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities
Act) is delivered, not misleading, or (2) if for any other reason it shall be necessary, in the reasonable judgment of the Company, during such same period to amend or supplement the Prospectus or to file under the Exchange Act any document
incorporated by reference in the Prospectus in order to comply with the Securities Act or the Exchange Act, or (3) if it shall be necessary during such same period to amend or supplement an Issuer Free Writing Prospectus in order for the Issuer
Free Writing Prospectus, as so amended or supplemented, not to conflict with the information then contained in the Registration Statement, then in each case notify the Remarketing Agent and, upon its request, file such document and prepare and
furnish without charge to the Remarketing Agent and to any dealer in securities as many copies as the Remarketing Agent may from time to time reasonably request of an amended or supplemented Prospectus that will correct such statement or omission or
effect such compliance or an amended or supplemented Issuer Free Writing Prospectus that will not conflict with the Registration Statement; 

(ix) during the time between the applicable Commencement Date and the Remarketing Settlement Date, prior to filing with the
Commission (a) any amendment to the Registration Statement or supplement to the Prospectus or (b) any Prospectus pursuant to Rule 424 under the Securities Act, furnish a copy thereof to the Remarketing Agent; and not file any such
amendment or supplement that shall be reasonably disapproved by the Remarketing Agent; 

  
 P-11 

 (x) as soon as practicable, but in any event not later than eighteen months,
after the date of a Successful Remarketing, to make generally available to its security holders an earnings statement of the Company (which need not be audited) complying with Section 11(a) of the Securities Act and the rules and regulations
thereunder (including, at the option of the Company, Rule 158 under the Securities Act); and 
 (xi) take such action as the
Remarketing Agent may reasonably request in order to qualify the Remarketed Notes for offer and sale under the securities or “blue sky” laws of such jurisdictions as the Remarketing Agent may reasonably request and will continue such
qualifications in effect so long as required for distribution of the Remarketed Notes; provided that in no event shall the Company be required to qualify as a foreign corporation in a jurisdiction in which it is not so qualified, to file a general
consent to service of process in any jurisdiction or to submit to any requirements which it deems unduly burdensome. 
 (b) The Company
shall pay: (i) the costs incident to the preparation and printing of the Registration Statement, if any, any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Prospectus and any other Remarketing Materials and any amendments or
supplements thereto; (ii) the costs of distributing the Registration Statement, if any, any Prospectus and any other Remarketing Materials and any amendments or supplements thereto; (iii) any fees and expenses of qualifying the Remarketed
Notes under the securities laws of the several jurisdictions as provided in Section 5(a)(xi) and of preparing, printing and distributing a Blue Sky Memorandum, if any (including any related reasonable fees and expenses of counsel to the
Remarketing Agent); (iv) any fees charged by investment rating agencies for rating of the Remarketed Notes; (v) all other costs and expenses incident to the performance of the obligations of the Company hereunder and the Remarketing Agent
hereunder; and (vi) the reasonable fees and expenses of counsel to the Remarketing Agent in connection with the review by the Financial Industry Regulatory Authority, Inc. of the Remarketed Notes. 

(c) The Company shall furnish the Remarketing Agent with such information and documents as the Remarketing Agent may reasonably request in
connection with the transactions contemplated hereby, and to make reasonably available to the Remarketing Agent and any accountant, attorney or other advisor retained by the Remarketing Agent such information, and such access to the appropriate
officers, employees and accountants of the Company, that parties would customarily require, and reasonably requested by the Remarketing Agent, in connection with a due diligence investigation conducted in accordance with applicable securities laws.

 (d) Between the applicable Commencement Date and the applicable Remarketing Settlement Date, the Company will not, without the prior
written consent of the Remarketing Agent (which consent may be withheld at the reasonable discretion of the Remarketing Agent), directly or indirectly, sell, offer, contract to sell or grant any option to sell, or otherwise dispose of, any debt
securities which mature more than one year after the applicable Remarketing Settlement Date of the Company similar to the Remarketed Notes. 

(e) The Company represents and agrees that, unless it obtains the prior written consent of the Remarketing Agent, which consent shall not be
unreasonably withheld, and the Remarketing Agent represents and agrees that, unless it obtains the prior written consent of the Company, it has not made and will not make any offer relating to the Remarketed Notes that would constitute an Issuer
Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Act), required to be filed by the Company with the Commission or

  
 P-12 

 
retained by the Company under Rule 433; provided that, if prepared and used in accordance with Section 5(f) of this Agreement, such prior written consent shall be deemed given with
respect to any final term sheet. Any such free writing prospectus consented to in writing by the Company or the Remarketing Agent, as the case may be, is hereinafter referred to as a “Permitted Free Writing Prospectus”. The Company
represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus” (as defined in Rule 433 of the Securities Act), and has complied and will comply with the
requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping. 

(f) The Company will prepare a final term sheet relating to the Remarketed Notes, containing only information that describes the final terms
of the Remarketed Notes after providing the Remarketing Agent and its legal counsel with a reasonable opportunity to review and comment on such final term sheet (such final term sheet to be in form and substance as last reviewed by the Remarketing
Agent and the Company), and will file such final term sheet within the period required by Rule 433(d) of the Securities Act following the date such final terms have been established for the Remarketed Notes. Any such final term sheet is an Issuer
Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement.

subsidiaries taken as a whole, in the reasonable judgment of the Remarketing Agent, so material and adverse as to make it impracticable or inadvisable to proceed with the completion of the Remarketing on the terms and in the manner contemplated in
the Disclosure Package (a “Material Adverse Change”). 
 (c) The representations and warranties of the Company contained
herein shall be true and correct in all material respects on and as of the applicable Remarketing Date and Remarketing Settlement Date, and the Company shall have performed in all material respects all covenants and agreements contained herein and
in the Purchase Contract and Pledge Agreement to be performed on its part at or prior to such date.

 (iii) for the period from the Commencement Date to
such Remarketing Settlement Date, there has not occurred any Material Adverse Change; 
 (iv) the representations and
warranties of the Company in Section 3 of this Agreement are true and correct in all material respects on and as of the applicable Remarketing Settlement Date.

subsidiaries included or incorporated by reference in the Registration Statement or the Remarketing Materials, containing statements and information of the type ordinarily included in accountants’ “comfort letters” with respect to
certain financial information contained in the Remarketing Materials, if any. 
 (f) Each of counsel for the Company and the Company’s
General Counsel shall have furnished to the Remarketing Agent their opinion letter with respect to the Remarketed Notes, addressed to the Remarketing Agent and dated the applicable Remarketing Settlement Date, addressing such matters with respect to
the Notes as are set forth in such counsels’ opinion letters furnished pursuant to Section 7(a)(ii) of the Underwriting Agreement, adapted as necessary to relate to the securities being remarketed hereunder and to the Remarketing

adaptations being reasonably acceptable to the Remarketing Agent. 

  
 P-14

Date, there shall not have occurred any of the following: (i) trading in the Company’s common stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock
Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, or (iii) any outbreak or
material escalation of hostilities or other calamity or crisis if the effect of any such event described in this clause (iii) on the financial markets of the United States, in the reasonable judgment of the Remarketing Agent, makes it
impracticable or inadvisable to proceed with the consummation of the Remarketing on the terms and in the manner contemplated in the Disclosure Package and the Prospectus. 

Section 7. INDEMNIFICATION. 
 (a)
The Company agrees to indemnify and hold harmless the Remarketing Agent, its directors and officers and each person, if any, who controls the Remarketing Agent within the meaning of Section 15 of the Securities Act or Section 20 of the

necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any Registration Statement, Issuer Free Writing Prospectus, the Prospectus or any amendment or
supplement thereto, any related preliminary prospectus supplement (or contained in any Registration Statement after it first becomes effective but prior to the date of a Successful Remarketing or in any prospectus forming a part thereof during such
period), or any Private Placement Marketing Materials, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

 (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred by such Company Indemnified
Party, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or
omission, or any such alleged untrue statement or omission; provided that any such settlement is effected with the written consent of the Company; and 

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably
incurred by such Company Indemnified Party in investigating, preparing for or defending against any subpoena or litigation, or any proceeding, subpoena or investigation by any governmental agency or body, whether commenced or threatened, or any
loss, claim, damage, liability or action whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

(b) The Remarketing Agent agrees to indemnify and hold harmless the Company, its directors and officers, and each person, if any, who controls
the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act (each, a “Remarketing Agent Indemnified Party”) against any and all loss, liability, claim, damage and expense
described in the indemnity contained in Section 7(a) hereof, to which such Remarketing Agent Indemnified Party may become subject under the Securities Act, the Securities Exchange Act, other federal or state statutory law or regulation or
otherwise, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in any Registration Statement, Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto,
any related preliminary prospectus supplement (or contained in any Registration Statement after it first becomes effective but prior to the date of a Successful Remarketing or in any prospectus forming a part thereof during such period), or any
Private Placement Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by the Remarketing Agent expressly for use therein. The indemnity agreement of the Remarketing Agent contained in this
Section 7(b) shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling person. 

(c) Each Company Indemnified Party or Remarketing Agent Indemnified Party (in any such case, an “Indemnified Party”) shall
give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it, if a claim in respect thereof is to be made against the indemnifying party under Section 7(a) or 7(b) hereof, but failure to so
notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure, provided that
the failure to notify such indemnifying party shall not relieve such indemnifying party from any liability that it may have to an Indemnified Party otherwise than under Section 7(a) or 7(b) above. Counsel to the Indemnified Parties shall be
selected as follows: counsel to the Company Indemnified Parties shall be selected by the Remarketing Agent, and counsel to the Remarketing Agent Indemnified Parties shall be selected by the Company. An indemnifying party may, jointly with any other
indemnifying party similarly notified, participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of an Indemnified Party) also be
counsel to such Indemnified Party, and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the indemnifying party will not 

  
 P-16 

 
be liable to such Indemnified Party under this Section 7 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than
reasonable costs of investigation. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Company Indemnified Parties and the
fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Remarketing Agent Indemnified Parties, in each case in connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the Indemnified Parties, settle or compromise or consent to the entry of any judgment with respect
to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or
Section 8 hereof (whether or not the Indemnified Parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnified Party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any Indemnified Party. 

(d) If at any time an Indemnified Party shall have requested an indemnifying party to reimburse such Indemnified Party for fees and expenses
of counsel as contemplated by this Section 7, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) hereof effected without its written consent if (i) such settlement
is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered
into and (iii) such indemnifying party shall not have reimbursed such Indemnified Party in accordance with such request prior to the date of such settlement 

Section 8. CONTRIBUTION. 
 If the indemnification
provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an Indemnified Party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such Indemnified Party as a result of such losses, liabilities, claims, damages and expenses incurred by such Indemnified Party, as incurred, in such proportion as is appropriate to reflect the relative
fault of the Company, on the one hand, and of the Remarketing Agent, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and the Remarketing Agent, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by the Remarketing Agent, on the other hand, and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and the Remarketing Agent agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other
method of allocation that does not take account of the equitable considerations referred to above in this Section 8. The aggregate 

  
 P-17 

 
amount of losses, liabilities, claims, damages and expenses incurred by an Indemnified Party and referred to above in this Section 8 shall be deemed to include any legal or other expenses
reasonably incurred by such Indemnified Party in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any
such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each officer and director of the Remarketing Agent, and each person, if any, who controls the Remarketing Agent within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Remarketing Agent, and each officer and director of the Company, and each person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The remedies provided for in Section 7 and this Section 8 are not exclusive and shall not limit any
rights or remedies which may otherwise be available to any Indemnified Party at law or in equity. 
 Section 9. RESIGNATION AND REMOVAL OF THE
REMARKETING AGENT. 
 The Remarketing Agent may, upon 30 days’ prior written notice, resign and be discharged from its duties and obligations
hereunder, and the Company may remove the Remarketing Agent by written notice at any time, in the case of a resignation, delivered to the Company and the Purchase Contract Agent and, in the case of a removal, delivered to the Remarketing Agent and
the Purchase Contract Agent; provided, however, that no such resignation nor any such removal shall become effective until the Company shall have appointed at least one nationally recognized broker-dealer as a successor Remarketing
Agent and such successor Remarketing Agent shall have entered into a remarketing agreement with the Company, in which it shall have agreed to conduct the Remarketing in accordance with the Purchase Contract and Pledge Agreement in all material
respects. 
 In any such case, the Company will use commercially reasonable efforts to appoint a successor Remarketing Agent and enter into such a
remarketing agreement with such person as soon as reasonably practicable. 
 Section 10. DEALING IN SECURITIES. 

The Remarketing Agent, when acting as the Remarketing Agent or in its individual or any other capacity, may, to the extent permitted by law, buy, sell, hold
and deal in any of the Remarketed Notes, Corporate Units, Treasury Units or any of the securities of the Company (collectively, the “Securities”), but shall not be obligated to purchase any of the Remarketed Notes for its own
account. The Remarketing Agent may exercise any vote or join in any action which any beneficial owner of such Securities may be entitled to exercise or take pursuant to the Indenture with like effect as if it did not act in any capacity hereunder.

  
 P-18 

 Section 11. REMARKETING AGENT’S PERFORMANCE; DUTY OF CARE. 

The duties and obligations of the Remarketing Agent shall be determined solely by the express provisions of the Transaction Documents. No implied covenants or
obligations of or against the Remarketing Agent shall be read into any of the Transaction Documents. In the absence of bad faith, willful misconduct or gross negligence on the part of the Remarketing Agent, the Remarketing Agent may conclusively
rely upon any document furnished to it, as to the truth of the statements expressed in any of such documents. The Remarketing Agent shall be protected in acting upon any document or communication reasonably believed by it to have been signed,
presented or made by the proper party or parties. The Remarketing Agent shall have no obligation to determine whether there is any limitation under applicable law on the Reset Rate on the Notes or, if there is any such limitation, the maximum
permissible Reset Rate on the Notes, and it shall rely solely upon written notice from the Company (which the Company agrees to provide prior to the third Business Day before the applicable Remarketing Date) as to whether or not there is any such
limitation and, if so, the maximum permissible Reset Rate. The Remarketing Agent, acting under this Agreement, shall incur no liability to the Company or to any holder of Remarketed Notes in its individual capacity or as Remarketing Agent for any
action or failure to act, on its part in connection with a Remarketing or otherwise, except if such liability is (a) judicially determined to have resulted from its failure to comply with the terms of this Agreement or bad faith, gross
negligence or willful misconduct on its part or (b) determined pursuant to Section 7 or 8 of this Agreement. The provisions of this Section 11 shall survive the termination of this Agreement and shall survive the resignation or
removal of the Remarketing Agent pursuant to this Agreement. 
 Section 12. TERMINATION. 

This Agreement shall automatically terminate (a) as to the Remarketing Agent on the effective date of the resignation or removal of the Remarketing Agent
pursuant to Section 9 of this Agreement and (b) on the earlier of (i) the occurrence of a Termination Event and (ii) the Business Day immediately following the Purchase Contract Settlement Date. Notwithstanding any termination of
this Agreement, in the event there has been a Successful Remarketing, the obligations set forth in Section 4 hereof shall survive and remain in full force and effect until all amounts payable under said Section 4 hereof shall have been
paid in full. 
 Section 13. REIMBURSEMENT OF REMARKETING AGENT’S EXPENSES. 

If this Agreement shall be terminated pursuant to Section 12 or if the settlement of the Remarketed Notes does not occur in connection with a Successful
Remarketing because of any of the events referred to in Section 6(h), then the Company shall not then be under any liability to the Remarketing Agent except as provided in Section 5(b), 7 and 8; but, if for any other reason the settlement
of the Remarketed Notes does not occur in connection with a Successful Remarketing, the Company will reimburse the Remarketing Agent for all out-of-pocket expenses,
including fees and disbursements of counsel, reasonably incurred by the Remarketing Agent in making preparations for the settlement of the Remarketed Notes, but the Company shall then be under no further liability to the Remarketing Agent with
respect to such failed settlement of the Remarketed Notes except as provided in Sections 5(b), 7 and 8. 

  
 P-19 

 Section 14. USA PATRIOT ACT. 

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)), the Remarketing Agent is required to obtain, verify and record information that identifies its respective clients, including the Company, which information may include the name and address of its respective clients, as well
as other information that will allow the Remarketing Agent to properly identify its clients. 
 Section 15. NO FIDUCIARY DUTY. 

The Company hereby acknowledges that (a) the transactions contemplated under this Agreement are arm’s-length
commercial transactions between the Company, on the one hand, and the Remarketing Agent and any affiliate through which it may be acting, on the other hand, (b) the Remarketing Agent is not acting as a fiduciary of the Company and (c) the
Company’s engagement of the Remarketing Agent in connection with the Remarketing is as an independent contractor and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in
connection with the Remarketing (irrespective of whether the Remarketing Agent has advised or is currently advising the Company on related or other matters, and the Remarketing Agent shall have no responsibility or liability to the Company with
respect to the transactions contemplated hereby except the obligations expressly set forth in this Agreement). The Company agrees that it will not claim that the Remarketing Agent has rendered advisory services of any nature or respect, or owe a
fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

removal of the Remarketing Agent pursuant to this Agreement or the termination and cancellation of this Agreement. 
 Section 19. GOVERNING LAW.

provision of this Agreement shall be held or deemed to be or shall, in fact, be invalid, inoperative or unenforceable as applied in any particular case in any or all jurisdictions because it conflicts with any provisions of any constitution,

shall constitute one and the same agreement. Delivery by telecopier or other form of electronic communication of an executed counterpart of a signature page to this Amendment shall be effective as delivery of an original executed counterpart of this
Amendment, it being understood and agreed that the words “execution,” “signed,” “signature,” and words of similar import in, or with respect to, any Loan Document shall be deemed to include electronic signatures or the
keeping of records in electronic form (including, without limitation, the execution by means of “DocuSign”, or other similar platform or service approved by the Administrative Agent), each of which shall be of the same effect, validity and
enforceability as manually executed signatures or a paper-based recordkeeping system, as the case may be, to the extent and as 

  

					
		  		  	THE SHERWIN-WILLIAMS COMPANY
		  	3	  	Amendment No. 14 to Credit Agreement

accordance with, the laws of the State of New York. 
 SECTION 7.  WAIVER OF JURY TRIAL. EACH PARTY HERETO
HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AMENDMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 

SECTION 8.  Jurisdiction; Consent to Service of Process.

or proceeding arising out of or relating to this Amendment, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding
